Opis:
The main purpose of the article is to establish the level of knowledge about fertility among female students of the University of Zielona Góra. The presented analyses used part of the empirical material from the project “The role of fertility assumptions in the formation of procreative intentions” carried out on a representative sample of full-time female students of the University of Zielona Góra. The respondents have the highest level of fertility knowledge related to changes in women’s reproductive abilities with age. However, it should be noted that their awareness in this aspect is rather medium. For the most part, they correctly identify the age at which the woman is most fertile and the age at which her ability to conceive is significantly reduced. However, the vast majority of respondents are convinced that the process of reducing the ability of women to become pregnant begins later than in reality. As for the other two dimensions of fertility knowledge – the dimension related to estimating the chances of getting pregnant and the dimension related to infertility – the women are characterised by their low or average level. Most of the respondents overestimate the chances of pregnancy of a young woman (up to 25 years old), who had unprotected intercourse at the time of ovulation and a woman who, aged 25–30, had unprotected intercourse regularly during a period of one year. More than half of female students are aware of the scale of infertility in Poland, but at the same time most of them overestimate the effectiveness of in vitro fertilisation. The results obtained are similar to those obtained by researchers from other countries. Therefore, it is necessary to postulate including to the educational program the knowledge about the specificity of the human body, which is characterised by limited ability to conceive a child and changes in the fertility level of women appearing with age.

Opis:
The connection between fertility of parents and their children has been investigated many times over the past century. It seems to be insignificant among pre-transitional populations, but becomes more important over time, especially in developed countries. Following Pearson’s example, it was widely adopted to use simple correlation analyses in such studies. In this study we will present how to use more advanced statistical models and methods to determine the occurrence and strength of examined relationships. Thus, we aim to investigate the intergenerational transmission of fertility in contemporary populations (in the case of the motherdaughter relation in Austria) using the zero-inflated Poisson regression model. Using this model in fertility analysis allows us to treat childlessness as a qualitatively different state with possibly different determinants than parenthood (regardless of the number of children). Bayesian inference in this study enables us to obtain covariates’ distributions as well as distributions of covariates’ nonlinear functions (including their uncertainty) and allows us to incorporate our prior knowledge.

Opis:
This study analyses and compares the fertility behaviour and childbearing plans of Polish migrant families in Ireland and those of their counterparts – families in Poland. The study has a comparative and explanatory character and applies both quantitative and qualitative methods. The analysis is based on the author’s own data collected from an online survey of Polish family units in Ireland in 2014 and compared with secondary data on families in Poland retrieved from the 2011 Gender and Generation Survey (GGS). My research reveals fertility postponement and fewer families with children among migrant families; nonetheless, migrant parents have more children than their counterparts in Poland. The results highlight the significance of socio-economic and institutional contexts. The study also reveals a dichotomisation of fertility strategies within the migrant population, with distinct differences in the number of children, transition age to parenthood, and further fertility intentions between migrants who became parents in Poland and those who did so after the move. The results also provide insights into the childbearing motivations and fertility patterns of recent Polish migrants and contribute to the discussion of migrants’ fertility in general.

The text aims at describing spatial distribution of people aged 60+ in Poland between 1991–2011 and showing correlation between aging of society and fertility. The analysis revels that in those regions of Poland where the number of people aged 60+ is highest, the fertility rate is lowest, however important differences between regions and in time were observed. Therefore no common and unvarying pattern was observed.

Opis:
The article describes the variation of fertility in Poland by voivodships in the period 1990–2009, separately for urban and rural areas. The analysis is based on the total fertility rate, the age-specific fertility rates (fertility patterns), and a median age of childbearing and their change over time. These variables are used to identify groups of similar voivodships. The underlying changes, whereby the peak in the age-specific fertility is shifted towards older age groups, demonstrate patterns of fertility transformation, which can be observed in several areas of Poland. It has been shown that the changes in fertility by voivodships were not homogeneous as to the intensity, but similar to the direction. A similar trend has been observed for changes in the total fertility rate. However, these considerations do not allow to believe that in all voivodships timing of fertility was a decisive factor of observed changes. In some voivodships the quantum effects were more important. This suggests that the transformation of fertility in different areas of Poland was not driven by the same determinants.

Opis:
Long-run impact of economic growth on fertility trends is ambiguous and sensitive for in-time variations. Noticeably, over last decades, economic growth has led to significant falls in total fertility rates in many countries. However, recently, in high-income economies a kind of ‘fertility rebound’ emerged (Gold-stein, 2009; Luci and Thevenon, 2011; Day, 2012), which supports the hypothesis that reversal trends in total fertility rates are mainly attributed to economic growth. The paper unveils the relationship between total fertility rate changes and economic growth in 18 selected countries with fertility rebound observed, over the period 1970–2011, and detects the GDP-threshold at which the fertility rebound emerged. To report on the relationship we deploy longitudinal data analysis assuming non-linearity between examined variables. The data applied are exclusively derived from World Development Indicators 2013. Our main findings support the hypothesis on U-shaped relationship between the total fertility rate and economic growth in analyzed countries in 1970-2011. Along with the previous, we project the minimum level of GDP per capita (GDP-threshold) when the fertility rebound takes place.

Opis:
Osoba ludzka jest istotą płciową. Seksualność, związana z płodnością, jest jedną z podstawowych sfer życia małżeńskiego. Chociaż seksualność i płodność towarzyszą mężczyznom i kobietom przez całe życie, pierwsze lata życia małżeńskiego są szczególnym czasem ich doświadczania. Ten czas jest zwykle związany z pozytywnymi przeżyciami, które właściwie kształtują i rozwijają związek i wyrażają go w pełni jego bogactwa. Jednak seksualność może być również źródłem kryzysów, które pojawiają się na różnych płaszczyznach życia w pierwszych latach małżeństwa, a zwłaszcza po urodzeniu pierwszego dziecka. Towarzyszenie małżeństwom w przezwyciężaniu różnych kryzysów jest jednym z ważnych zadań, jakie papież Franciszek zaleca Kościołowi w swojej adhortacji apostolskiej Amoris laetitia. Celem niniejszej pracy jest próba dostrzeżenia roli i znaczenia poradni rozpoznawania płodności w towarzyszeniu parom małżeńskim w sytuacjach kryzysowych związanych ze sferą seksualności i płodności w pierwszych latach życia małżeńskiego.
A human person is a sexual being. Sexuality, connected with fertility in its very nature, is one of the fundamental spheres of married life. Although sexuality and fertility accompany men and women throughout their whole lives, the fi rst years of married life are a special time of experiencing those phenomena. This time is usually connected with positive experiences, which properly shape and develop the couple’s relationship, and express it in the fullness of its wealth. However, the sexual relationship may also be the source of multi-fi eld crises which arise in the fi rst years of married life, and particularly after the birth of the couple’s fi rst child. Accompanying married couples in overcoming various crises is one of the important tasks which Pope Francis gives to the Church in the Apostolic Exhortation Amoris Laetitia. The aim of the present paper is to try to see the role and meaning of the centers teaching fertility awareness in accompanying married couples in crises connected with the sphere of sexuality and fertility during the fi rst years of married life.

Opis:
Aim of the study: The aim of this study was to estimate some basic data related to the fertility in the chosen groups of Polish and Czech women. We have tried to acquire and analyze the attitudes and beliefs of these women in motherhood and the desire to have children. These data enable to verify the interdisciplinary hypothesis explaining the decline of birth rate and low fertility in European countries. Materials and methods: The authors performed the survey by means of a questionnaire formulated after a comprehensive discussion of possible reasons of birth rate decline. They have tried through the questions of the survey to verify the hypothesis that the decline is the result of the cumulative mental changes occurring in contemporary societies. The questionnaire completed 90 Polish women students pursuing complementary studies of nursing in Higher School of Applied Sciences in Nysa, during the academic year 2012/2013. The questionnaire also completed 53 Czech women students pursuing part-time studies and training at the Tomas Bata University in Zlin (the Czech Republic). Results: The above surveyed 90 Polish women gave birth to 132 children, so fertility rates is 1.46. The average age at the birth of the first child was 24.7 years, of the second child 27.5 and of the third child 31.7 years. The surveyed 53 Czech women gave birth to 86 children, so fertility rates is 1.62. The average age at birth of the first child was 24.7 years, of the second child 27.2 and of the third child 27,5 years. The authors present also convictions, beliefs and attitudes of the women under study. Conclusions: The multifaceted and interdisciplinary hypothesis (theoretical model) formulated at the outset of our work, can be useful for attempts to estimate the pro-family attitudes in different populations of women. The results in the light of compliance with the proposed theoretical model allow for the formulation of proposals for action, which would counteract the decline in birth rates.
Cel pracy: Celem pracy była ocena podstawowych danych dotyczących płodności w wybranych grupach kobiet w Polsce i Czechach. Próbowaliśmy także analizować postawy i przekonania tych kobiet odnośnie macierzyństwa i chęci posiadania dzieci. Dane te pozwalają na sprawdzenie interdyscyplinarnej hipotezy wyjaśniającej spadek liczby urodzeń i niskiej dzietności w krajach europejskich. Materiał i metody: Badania przeprowadzono za pomocą kwestionariusza sformułowanego po dokładnym omówieniu możliwych przyczyn spadku liczby urodzeń. Jedną z nich jest kumulacja zmian psychicznych zachodzących we współczesnych społeczeństwach. Ankietę wypełniło dziewięćdziesiąt Polek, studentek uzupełniających studiów pielęgniarskich Wyższej Szkoły Zawodowej w Nysie, w roku akademickim 2012/2013. Ankieta została również przeprowadzona wśród pięćdziesięciu trzech studentek z Czech. Były to kobiety, które studiują w niepełnym wymiarze czasu na Uniwersytecie Tomasza Baty w Zlinie. Wyniki: Ankietowane Polki urodziły łącznie 132 dzieci, zatem współczynnik dzietności w tej grupie wynosi 1,46. Średni wiek ankietowanej w momencie narodzin pierwszego dziecka wynosił 24,7 lat, w momencie narodzin drugiego dziecka: 27,5 i trzeciego dziecka: 31,7 lat. Badane kobiety z Czech urodziły 86 dzieci, więc współczynnik dzietności wynosi 1,62. Średni wiek urodzenia pierwszego dziecka w tej grupie kobiet to 24,7 lat, drugiego dziecka 27,2 i trzeciego dziecka 27,5 lat. Autorzy przedstawiają również przekonania i postawy kobiet objętych badaniem, odnośnie macierzyństwa. Wnioski: Wielopłaszczyznowa i interdyscyplinarna hipoteza (model teoretyczny), sformułowana na początku pracy, opisująca spadek liczby urodzeń, może być przydatna do prób oszacowania prorodzinnych postaw w różnych populacjach kobiet. Wyniki w świetle zgodności z proponowanym modelem teoretycznym pozwalają na formułowanie wniosków dotyczących działań, które mogłyby przeciwdziałać spadkowi liczby urodzeń.

Soil fertility evaluation has been considered as a most effective tool for sustainable planning of a particular region. This study was conducted to determine the soil fertility status of the Agricultural Research Station, Pakhribas, Dhankuta, Nepal. The total 60 soil samples were collected randomly at a depth of 0-20 cm by using the soil sampling auger. For identification of soil sampling points A GPS device was used. The collected samples were analyzed for their texture, pH, OM, N, P₂O₅, K₂O, Ca, Mg, S, B, Fe, Zn, Cu and Mn status following standard methods in the laboratory of Soil Science Division, Khumaltar. The Arc-GIS 10.1 software was used for soil fertility maps preparation. The observed data revealed that soil was dark yellowish brown (10YR 4/4) and yellowish brown (10YR 5/6) in colour, and single grained, granular and sub-angular blocky in structure. The sand, silt and clay content were 56.61±0.97%, 27.62±0.56% and 15.77±0.58%, respectively and categorized as loam, sandy loam and sandy clay loam in texture. The soil was very acidic in pH (4.66±0.07) and very low in available sulphur (0.53±0.11mg/kg), available boron (0.24±0.07mg/kg). The organic matter (1.34±0.07%), total nitrogen (0.09±0.003mg/kg), available calcium (605.70±31.40mg/kg), available magnesium (55.96±4.67mg/kg) and available zinc (0.54±0.22mg/kg) were low in status. Similarly, available potassium (115.98±9.19 mg/kg) and available copper (1.13±0.09 mg/kg) were medium in status. Furthermore, available manganese (36.31±2.82mg/kg) was high, whereas available phosphorus (105.07±9.89 mg/kg) and available iron (55.80±8.89 mg/kg) were very high in status. The soil fertility management practice should be adopted based on the determined status in the field for the sustainable production of crops. The future research strategy should be built based on the soil fertility status of the research farm.

Opis:
Demographic changes are one of the indicators of sustainable development, expressed by the value of the natural increase in the human population, resulting directly from the fertility level, which is the subject of this article. Human fertility is a complex potential conditioned by the environmental, social, and economic factors. The multi-dimensional relations of fertility that may affect its level, constitute an unlimited field of research, study, and analysis. The inter-disciplinary scope of fertility research conducted by the authors has shown that fertility is an issue that, in its historical, social, political, and medical aspects, has the potential of contributing to societal development and raising the standard of living. The aim of this article is to answer the question: whether and how the fertility of an individual has an impact on the idea of sustainable development. To achieve this, the available literature was analysed and synthesised, as well as supplemented with information provided by experts in the field. The article incorporates presentations of selected fertility determining factors, methods of measuring fertility potential, and diverse contexts, such as the impact of fertility on history and its relationship with the freedom of the human individual. Moreover, the authors present the relationship between the fertility of an individual, and the assumptions and postulates of the idea of sustainable development.
Jednym ze wskaźników zrównoważonego rozwoju są zmiany demograficzne wyrażane wartością przyrostu naturalnego populacji ludzkiej, którego stan wynika bezpośrednio z poziomu płodności (fertility) będącej przedmiotem rozważań niniejszego artykułu. Płodność człowieka jest złożonym potencjałem uwarunkowanym czynnikami środowiska przyrodniczego, społecznego i gospodarczego. Wielowymiarowe powiązania płodności, które mogą wpłynąć na jej stan, stanowią nieograniczone pole badań, studiów i analiz. Interdyscyplinarny zakres badań płodności, przeprowadzony przez autorów, pokazał, że płodność jest zagadnieniem, które zarówno w aspekcie historycznym, społecznym, politycznym i medycznym jest potencjałem przyczyniającym się do rozwoju społeczeństw i poziomu ich życia. Celem artykułu jest odpowiedź na pytanie: czy i w jaki sposób płodność jednostki ma znaczenie dla idei zrównoważonego rozwoju. By to osiągnąć, przeprowadzono analizę oraz syntezę dostępnego piśmiennictwa uzupełnioną o informacje przekazane przez ekspertów z przedmiotowego zakresu. W pracy zostały zaprezentowane: wybrane czynniki warunkujące płodność, sposoby mierzenia potencjału płodności oraz zróżnicowane konteksty, takie jak wpływ płodności na historię i jej powiązania z wolnością jednostki ludzkiej. Ponadto autorzy przedstawili powiązania między płodnością jednostki a założeniami oraz postulatami idei zrównoważonego rozwoju.

Opis:
The cross-sectional association between female labour force participation rates and fertility in developed countries shifted from negative to positive during the 1980s. Ever since then, researchers have applied different statistical approaches; therefore, the present study re-evaluates the results by applying a distinct strategy to the data from2000 to 2020 for 32 countries belonging to the Organization for Economic Co-operation and Development (OECD). Specifically, the data analysis discussed here implemented the so-called „unified“ model, thereby extending the analysis beyond the limitations of the fixed effects (FE) method; namely, by decomposing coefficients within (time-series) and between (cross-sectional) countries‘ effects, the study increased the explanatory power of our statistical model on the relation between fertility level and female labour force participation rate. Eventually, the selected statistical approach has shown the potential to offer a better interpretation of results in comparison to previous studies. Finally, this study confirmed the persistence of a negative trend in a time-series association between labour force participation and fertility.

Opis:
This paper presents a theoretic synthesis of determinants of fertility decline in Poland in the post-war period. The differences in fertility determinants between the communist and post-communist periods are of particular interest. First, we present the changes in the number of births and their direct determinants: the number of women in reproductive age, forming lasting heterosexual relationships and the quantum and timing of fertility. The births’ decline in Poland is attributed to both quantum and timing effects and changes of union formation. In the second part, we discuss indirect determinants of fertility change by referring to main theoretical approaches to nuptiality and fertility, and by making use of research conducted in Poland. In the last section, we present a conceptual model distinguishing fertility determinants operating on the interconnected levels of production and reproduction system (the macro level), labour market and family (the meso level), and work and family social roles (the micro level). By showing how different factors operated differently in the Polish People’s Republic (until 1989) and during the post-communist transition, we analyse links between these determinants and importance of each of them.

Opis:
Breast cancer is the most common cancer among females worldwide. The mean age of breast cancer patients is > 60 yrs old, and it is seldom found in women < 40 yrs old (6.5%) and in very young women < 35 yrs old (0.6%). In young females, fertility and all its aspects are an additional therapeutic challenge. Before initiating treatment, the oncologist should offer effective contraception to be applied throughout the therapy, bearing in mind that fertility preservation is of utmost importance. When it comes to breast cancer in pregnancy, the attending physician should use a therapy which is safe for both the mother and the foetus. Chemotherapy, radiotherapy, hormonal therapy and immunotherapy can, to a lesser or greater degree, damage the ovarian function resulting in amenorrhea in women < 50 yrs (33–76%). However, owing to fertility preservation strategies, more and more pregnancies are successful, even in breast cancer survivors.

Opis:
Współcześnie, mierząc się ze spadkiem współczynników płodności oraz gwałtownym starzeniem się społeczeństw, kraje Unii Europejskiej są zmuszone do tego, by zredefiniować kwestie demograficzne swoich państw i odpowiedzieć na kluczowe pytania dotyczące imigrantów. Artykuł ma na celu zbadanie wpływu różnych grup etnicznych na europejską demografię oraz kształtujące się obecnie trendy w oparciu o zmienne gospodarcze, społeczne, ekonomiczne i finansowe. Przy użyciu danych z raportów OECD oraz Eurostatu, jak również case studies dla Francji i USA autorzy analizują kształtujące się obecnie trendy demograficzne, by przekonać się, że współczynnik płodności imigrantów jest znacznie wyższy niż urodzonych w tym kraju obywateli. To właśnie podstawowa różnica etniczna, która może mieć znaczący wpływ na demografię całej Europy.
Nowadays, countries of the European Union are facing a rapid decline in their fertility indicators. This factor, combined with ageing of societies, stimulates a need to redefine the demography, as well as answer key questions regarding the inflow of immigrants. This paper aims to ascertain the influence of various ethnic groups on European demography and the contemporary trends by using a set of economic, social, and financial variables. Utilizing data from OECD and Eurostat reports, as well as case studies of France and the US, the authors proceed to analyze the current demographic tendencies in order to find out whether immigrants and their offspring in France or the US might tend to be much more fertile than the countries’ native citizens. This turns out to be a major ethnic difference, which may have a significant impact on the demography of Europe as a whole.

From the 1990s. we note the considerable decrease in the fertility rate in Poland and the rise in the proportion of persons aged 60 years and more in population. The article is to demonstrate the dynamics of changes of both processes and to correlation between the two processes. For the description of the changes in the value of the fertility rate and the share of persons aged over 60 years we use a linear function of the trend, and to describe the relationship of both processes multiple linear regression.

Opis:
The aging of population is largely caused by falling fertility. To find out how fertility affects the share of the elderly people in the population, four variants of the UN World Population Prospects 2010 for Poland and Europe were examined, as well as selected indicators of population aging. The relatively high fertility and comparatively short life expectancy in Poland until the end of 1980s explain why its population aged much more slowly than other populations in Europe. In the last two decades the share of the elderly people kept increasing, mostly because of the deep decline in the number of births. For almost a decade now Poland has been one of the demographically old countries, although the aging process is relatively less pronounced in Poland than in Italy or Germany. In the medium variant of the UN forecast Polish fertility will be growing for the next few decades, but its level will not be high enough to ensure the minimum population replacement. Only in the high variant its growth will lead to rates of population reproduction higher than the minimum level. This situation might take place as early as the first half of the 2020s. The analysis of particular indicators illustrating the progress of demographic aging leads to a conclusion that even high fertility will not rejuvenate the age structure of Polish population, but it may considerably slow down the process of its aging.

Opis:
Political demography links demographic findings with public policies aimed at achieving state goals. Current challenge of population aging causes threat to internal financial stability and well-being of the elderly. Aging also questions countries’ international position due to possibly reduced financial capability to maintain geopolitical power, and in extreme situation of lowest low fertility also due to continuous, unstoppable decline in the population size. In case of Poland, aging alone would result in almost doubling expenditure on pensions and healthcare. To respond to social and geopolitical challenges, the government should primarily focus on policies aimed at stimulating births. To foster pronatalist policies, factors affecting fertility may be grouped into five categories: economic, cultural, psychological, infrastructural and unplanned. All these factors influence childbearing behaviour simultaneously. Some of them constitute barriers to fertility (which need to be eliminated) and the others facilitate fertility (and they need to be strengthened). The barriers include financial constraints, individualistic values, financial insecurity, union instability, insufficient support network and lack of family-friendly employment. Identified facilitators in turn include pension system linking benefits with number of children (family pension system) and family-oriented aspirations and values with religion as a vital ingredient. Father commitment to family life impacts both as facilitator and by eliminating barriers.

Research background: The decreasing fertility rate is a serious problem for policymakers as it affects the pension system as well as private consumption and savings. It seems reasonable to analyze whether fiscal policy may mitigate the low birthrate problem. Purpose of the article: In this paper we strive to answer the question whether fiscal incentives spur fertility if parents are rational. Methods: A theoretical economic model of utility maximization is applied to analyze the impact of fiscal policy on fertility. The conclusions are based on the analysis of comparative statics simulation calibrated for actual data from Poland. Findings & Value added: The results indicate that a substantial fertility effect can be obtained by raising subsidies for children or general benefits for families.

Opis:
Having a home of one’s own was enumerated by Hobcraft and Kiernan (1995) as one of the five pre-conditions for the entry to parenthood in industrialised eco- nomies. The importance of home ownership for the decision to become a parent has not been investigated for Poland, however. This article aims at filling partly this gap through examining the relationship between home ownership and first birth among Polish women born 1971–1981. This research issue is considered to be important due to a decline in the number of dwellings completed each year as well as the enormous increase in housing prices that were observed in Poland after 1989. Our empirical findings point out a strong and positive relationship between home ownership and entry to motherhood. More in-depth analyses show that this result is mostly to be attributed to the fact that parents-to-be condition the realisation of their childbearing plan made in the past on becoming a home owner. It is to be noted, that rental accommodation is a far less attractive option for persons planning a child, as is the residence at parents’ dwelling. These results are largely consistent with empirical findings of other researchers investigating this issue in other industrialised economies and suggest that difficulties with a home purchase are one of the reasons for fertility postponement in Poland.

Opis:
A field experiment was carried out in two vegetation seasons in the years 2012 and 2013 on very light soil at Kruszyn Krajeński, in the vicinity of Bydgoszcz, Poland. The aim of the study was to characterize morphological achenes and determine the fertility potential and real of cup plant (Silphium perfoliatum L.) plants derived from micropropagation grown under irrigation. Low fertility real of cap plant resulted from the participation of infertile fruit-achenes it means devoid of the seeds. Due to the fact that this plant is entered on the list of invasive species, this property may be desirable during plantation establishment. As a result, the plant will not be so easy to penetrate into the ecosystem and will not pose a threat to native biodiversity.

Opis:
Significant progress in oncology over the past years resulted in a noticeable improvement of mean survival rates of patients treated for malignant tumors. Particularly rewarding is the treatment of tumors in the pediatric and juvenile age group. A sizeable proportion of patients subjected to oncologic treatment, i.e. chemotherapy, radiotherapy and surgery, experience a limited procreative potential as a sequel of administered therapy. Among chemotherapeutics, some of the most toxic compounds are alkylating agents, e.g. cyclophosphamide, chlorambucil, melphalan and procarbazine. Severity of negative effects of cytostatics on the patients’ fertility depends largely on administered dose and patient’s age at the time of treatment. In the case of radiotherapy, severity of limitation of procreative potential correlates with total absorbed dose of radiation, irradiated body area and, as in the case of chemotherapy, on the patient’s age. Induced iatrogenic infertility is a tremendous problem for survivors, adversely affecting their quality of life. Apart of inherited genetic syndromes, no evidence is available suggesting that oncologic treatment instituted in the past in the parents might increase the risk of cancer or congenital malformations in their offspring. Thanks to the development of novel procreation-enhancing techniques, several options are currently available enabling preservation of procreative potential of oncologic patients. Prior to institution of antitumor therapy, persons who wish to preserve fertility should be offered cryopreservation of embryos, oocytes, sperm or of a sample of gonadal tissue, transposition of ovaries or hormonal suppression of oogenesis and spermatogenesis. Implementation of these techniques should provide young people with a chance to raise their own children.
Dzięki znacznemu postępowi w dziedzinie onkologii w ciągu kilku lat istotnie wzrósł średni czas przeżycia pacjentów leczonych z powodu nowotworów złośliwych, a szczególnie duże powodzenie odnotowuje się w leczeniu nowotworów wieku dziecięcego i młodzieńczego. Niemała liczba młodych osób przechodzących w przeszłości leczenie onkologiczne, w postaci chemioterapii, radioterapii, leczenia chirurgicznego, ma ograniczone możliwości prokreacyjne ze względu na zastosowaną terapię. Wśród chemioterapeutyków do najbardziej toksycznych substancji należą związki alkilujące, tj. cyklofosfamid, chlorambucyl, melfalan i prokarbazyna, przy czym stopień negatywnego oddziaływania cytostatyków na płodność pacjentów zależy w dużej mierze od zastosowanej dawki leku oraz wieku chorego. W przypadku radioterapii ograniczenie zdolności prokreacyjnych związane jest z całkowitą pochłoniętą dawką promieniowania, z polem napromieniania oraz, podobnie jak w przypadku chemioterapii, z wiekiem pacjenta. Wyindukowana jatrogennie bezpłodność stanowi olbrzymi problem dla ozdrowieńców, znacząco obniża ich jakość życia. Poza dziedzicznymi zespołami genetycznymi nie ma dowodów na to, że zastosowana w przeszłości u rodziców terapia przeciwnowotworowa zwiększa ryzyko raka albo wad wrodzonych u potomstwa. Dzięki rozwojowi technik wspomaganego rozrodu istnieje obecnie wiele metod pozwalających zachować zdolności rozrodcze u pacjentów onkologicznych. Przed rozpoczęciem terapii przeciwnowotworowej u osób pragnących zachować płodność należy zaproponować zamrożenie zarodków, oocytów, nasienia, fragmentu tkanki gonadalnej, transpozycję jajników lub hormonalną supresję oogenezy i spermatogenezy. Stosując ww. techniki, daje się tym młodym ludziom szansę na uzyskanie własnego potomstwa.

Opis:
In the developed countries, the age of becoming pregnant and giving birth to the first child is constantly delayed. This trend is also present in Poland. Many women postpone their decision about becoming mothers and some of them do not decide to have a child at all. An important question concerns reasons for postponing the decision or resignation from motherhood. The study was conducted in a group of 247 women aged 20 to 46 years (M = 29.67, SD = 4.54). The participants filled in the Polish version of Attitudes to Fertility and Childbearing Scale (AFCS), which enables the assessment of attitudes in terms of the three components: Importance for the future, Hindranceat present and Female identity. Higher average scores on Hindrance at present were obtained mainly by those women who were younger, single or living in an informal relationship, and those who studied and worked at the same time. The component Importance for the future was relevant for instance for married women. Female identity appeared important for married women living in rural areas. No statistically significant differences were found for level of education or financial status.
W krajach wysokorozwiniętych wiek zajścia w ciążę i urodzenia pierwszego dziecka stale się wydłuża. Tendencja ta obecna jest również w Polsce. Kobiety odkładają decyzję o zostaniu matkami, część z nich w ogóle nie decyduje się na dziecko. Pojawia się pytanie o przyczyny odkładania decyzji lub rezygnacji z macierzyństwa. W badaniach wzięło udział 247 kobiet w wieku 20–46 lat (M = 29,67; SD = 4,54). Uczestniczki wypełniły polskojęzyczną wersję Skali do Badania Postaw Wobec Płodności i Posiadania Dzieci, która pozwala na ocenę postaw w zakresie trzech wymiarów: Płodność – istotna w przyszłości, Płodność – przeszkoda w chwili obecnej oraz Płodność – tożsamość kobiety. Wyższe średnie wyniki w wymiarze Płodność – przeszkoda w chwili obecnej uzyskiwały przede wszystkim młodsze, wolne lub pozostające w nieformalnym stałym związku, łączące pracę i studia kobiety. Płodność – istotna w przyszłości była ważna m.in. dla uczestniczek pozostających w związkach małżeńskich. Płodność – tożsamość kobiety okazała się ważna dla kobiet mieszkających na wsi i pozostających w związku małżeńskim. Sytuacja finansowa, podobnie jak wykształcenie nie okazały się czynnikami, które w istotny statystycznie sposób różnicowałyby badane kobiety w zakresie postaw wobec płodności i posiadania dzieci.

Opis:
Research background: The phenomenon of low fertility in Poland is a vital subject of demographic analysis. In recent years, not only have there been changes in procreative and family models, but also in the age structure of society. This is particularly significant in the context of population ageing, which is becoming increasingly evident and brings numerous challenges such as increased burden on healthcare systems, a decrease in the active workforce, and the need to secure adequate retirement funds. Despite the desire to have children, many individuals refrain from making such a decision, and the reasons for this choice are diverse. Therefore, it was essential to conduct an analysis of the factors determining fertility in Poland, considering both the economic and social aspects. Understanding how the economic situation, labour market conditions, and changes in social structure impact on the decision-making process regarding childbearing is essential. Purpose of the paper: The objective of this article was to analyse fertility rates in Poland for the period 2004-2020. The conducted research identified the factors influencing the observed state of low generational replacement and determining their intensity. Methodology/Methods/Data sources: The data used in this article were sourced from the Central Statistical Office and covered the years 2004-2020. The study was based on literature concerning demography and econometrics. Three statistical methods were applied in the analysis of fertility in Poland: the Classical Method of Least Squares (CMLS) model, the Fixed Effects (FE) estimator, and the Random Effects (RE) estimator. Fertility analysis was conducted at regional level by dividing Poland into 16 administrative units (voivodeships). A panel model was employed for the analysis, and the results were subjected to Wald, Breusch-Pagan, and Hausman tests to compare the outcomes obtained from different models. Findings: The results of the analysis indicate that the economic situation and the labour market significantly influence the decision to have children in Poland. The trend of low fertility, although showing some increase, is still characteristic of the country compared to other EU nations. The analysis of the factors determining fertility is vital for understanding the decisions of young generations of Poles regarding parenthood.
Tło badań: Zjawisko niskiej dzietności w Polsce stanowi kluczowy obiekt analiz demograficznych. W ostatnich latach obserwuje się nie tylko zmiany w modelach prokreacyjnych i rodzinnych, ale także w strukturze wiekowej społeczeństwa. Jest to szczególnie istotne w kontekście starzenia się populacji, które staje się coraz bardziej widoczne. Starzejące się społeczeństwo niesie za sobą liczne wyzwania, takie jak wzrost obciążenia systemów opieki zdrowotnej, zmniejszenie aktywnej siły roboczej i konieczność zabezpieczenia odpowiednich środków na emerytury. Mimo że wiele osób pragnie mieć potomstwo, powstrzymują się od podjęcia takiej decyzji, a przyczyny tego wyboru są zróżnicowane. W związku z tym istotne jest przeprowadzenie analizy czynników determinujących dzietność w Polsce, z uwzględnieniem aspektów zarówno ekonomicznych, jak i społecznych. Konieczne jest zrozumienie, w jaki sposób sytuacja ekonomiczna, warunki na rynku pracy oraz zmiany w strukturze społecznej wpływają na proces podejmowania decyzji dotyczących posiadania dzieci. Cel artykułu: Artykuł ma na celu analizę dzietności w Polsce w okresie 2004-2020. Wykonane badania umożliwią identyfikację czynników wpływających na obserwowany stan niskiej zastępowalności pokoleń oraz określenie ich intensywności. Metodologia/Metody/Źródła danych: Dane wykorzystane w artykule pochodzą z Głównego Urzędu Statystycznego i obejmują lata 2004-2020. Praca opiera się na literaturze z zakresu demografii i ekonometrii. W analizie dzietności w Polsce zastosowano trzy metody statystyczne: model Klasycznej Metody Najmniejszych Kwadratów (KMNK), estymator o efektach ustalonych (FE) oraz estymator o efektach losowych (RE). Następnie przeprowadzono analizę dzietności w przekroju regionalnym, dzieląc Polskę na 16 jednostek administracyjnych (województw). Do analizy wykorzystano model panelowy, a wyniki poddano testom Walda, Breuscha-Pagana i Hausmana w celu porównania rezultatów uzyskanych z różnych modeli. Wyniki/Wnioski: Wyniki analizy wskazują, że sytuacja ekonomiczna i rynek pracy mają znaczący wpływ na decyzję o posiadaniu dzieci w Polsce. Trend niskiej dzietności, chociaż obserwuje się pewien jej wzrost, wciąż jest charakterystyczny dla kraju w porównaniu z innymi państwami UE. Analiza czynników determinujących dzietność jest istotna dla zrozumienia decyzji młodego pokolenia Polaków w kwestii posiadania potomstwa.

Opis:
Previous studies identified large differences between countries in the extent to which childbearing intentions are realised. Failure to realise an intention to become a parent was found to be particularly common in the post-socialist countries. In this paper we examine whether similarly low rates of realisation of fertility intentions can be found in Poland. We use two waves of the Polish Generations and Gender Survey (GGS-PL), conducted in 2010/2011 and 2014/2015. We first describe fertility intentions of Polish women and men as declared at the survey’s first wave. Next, we examine whether the short-term childbearing intentions expressed at wave 1 were followed by an actual birth by the second round of the data collection. For the respondents who did not get a child between waves 1 and 2, we analyse the stability of their fertility plans. We find that approximately 35% of the respondents who at wave 1 intended to have a child in the next three years actually had one by wave 2. Both realization and stability of fertility intentions varied markedly by gender and parity.

The analysis is based on data from the first wave of the Generations and Gender Survey GGS-PL. The results show: a) positive and statistically significant effect of employment on the risk of having a first and a second child, b) negative, although weak impact of the length of statutory maternity leave on the risk of having a second child. The results cast in doubt the effectiveness of the new reform that introduces the possibility of taking longer maternity leaves in order to boost fertility.

Opis:
In the 1990s, fertility was dropping rapidly in Poland. According to the GUS and the UN projections, low fertility may continue in the next decades. The procre- ative behaviour changes irreversibly affect the age structure of population. If the fertility level as low as it is today continued, the number of births would be ultimately reduced by almost half compared with the present numbers. However, the structure of population would be changing gradually. First the number of the pre-school children would change and then of those at school age. The high variant of the UN World Population Prospects is the only one where the number of the children aged 0–4 years is growing to the year 2020. If fertility does not change their number will, however, drop dramatically from ca 1.8 million that we have today to below 1 million in 2050. Decreasing fertility may distort the demographic structure in the long term by re- ducing the share of children and contributing to a relatively overrepresented proportion of old persons. Because of fertility falling from the 1990s and the appearance of baby boomers and baby busters, the size of the working-age population (15–64 years) will grow smaller after 2015. The aging process will also continue. The median age will grow to approx. 50 years in 2050. The dependency ratio will also increase and there will be 70 working-age persons per 100 persons aged 15–64 years, instead of slightly more than 40 that we have today.

Problem identification: The desire for motherhood is one of the top priorities for most female young cancer survivors. The risk of infertility after cancer therapy is an important concern with several physical and emotional consequences. This comprehensive literature review aims to summarize and contextualize recent research that has been carried out on female fertility after cancer, suggesting future research and clinical directions. Literature search: Searches included the keywords “cancer”, “female”, “adults”, and “fertility”. Studies were selected if focused on infertility issues in female cancer survivors. Data synthesis: Eight themes were identified: the effects of anticancer treatments on fertility; fertility preservation methods; international recommendations regarding infertility risk; health professionals’ attitudes towards fertility preservation; patient’s concerns regarding the risk of infertility; patients' information needs; and the impact of the risk of infertility in patient’s quality of life. Conclusions: Psycho-oncologists should be integrated in the oncofertility teams to assess patients’ needs before cancer treatment initiation.

This study was conducted to determine the fertility difference between silvofishery pond and conventional pond in Legonkulon, Subang, West Java. Sampling methods was used by collecting samples four times in the composite from five sampling points at six stations (three stations at silvofishery ponds and three stations at conventional ponds). The data were analyzed with comparative descriptive method. The results showed that average abundance of phytoplankton in the silvofishery pond is higher (1935 ind/l) than in the conventional pond (494 ind/l). Average abundance of zooplankton in the silvofishery pond found lower (383 individuals/L) than conventional pond (963 ind/l). Makrozoobenthos average abundance is not significantly different between silvofishery pond and conventional pond with average abundance of each 1162 and 1306 individuals/m2 respectively. Silvofishery pond with a composition of 20% mangrove and 80% ponds increased fertility of plankton and makrozoobenthos.

The aim of this article is to take a closer look at national Israeli policies in the domain of population growth. Demography plays a powerful role in understanding the Israeli society and the changes it has experienced over time. The “demographic struggle” presents the constant effort of the Jewish population to maintain, regardless of the costs, the numerical majority of the Jews in Israel. The central means to achieve the demographic dominance are the immigration policies and fertility rate, therefore the control over these factors of social life is of primary importance to the Israeli authorities. The methods of managing and influencing the two demographic indicators are discussed in the article in details, since the differences between the Arab and Jewish communities in this area are crucial. The article presents also briefly the role of demography in constituting ethnic democracy in Israel

Global climate change is a fact that affects all components of the environment. The main aim of this research was to conduct the retrospective monitoring of soils in the Trans-Ural Steppe Zone (Russia) and the analysis in changing of key climatic parameters for the periods 1937-1982 and 1982-2019. We investigated average temperatures and precipitation (monthly and annual) using archived data from a nearby weather station, as well as data from NASA and weather forecast websites. We identified a decrease of soil fertility and an increase in alkalinisation processes over the past 37 years for the studied area. Comparison of these periods showed an increasing the average monthly and annual air temperatures (on 1.4°C) and a decrease in the amount of precipitation in the summer (on 4.4 mm) period. We found that a more arid climate accelerates the rate of soil salinization due to the active evaporation of groundwater. Nevertheless, in some areas there were found the soil desalinization due to the change in the hydrologic regime and lowering of the groundwater level. In general, the climate changing in the studied region is consistent with global warming trend. Increased average annual temperature and reduced precipitation in summer period contribute to aridization of the region. Such conditions will more restrict soil fertility due to development of salinization and desertification processes.

Opis:
Polybrominated diphenyl ethers (PBDEs) are used as flame retardants. Due to their widespread use in many consumer products, PBDEs can be found in food as well as in the environment. Their presence has also been found in the human serum, human adipose tissue and human breast milk. Results of experimental studies suggest that the presence of PBDE in the environment is not neutral to our health. In rats and mice exposed to PBDE disturbances in thyroid hormone homeostasis and reproductive system such as changes in reproductive organs weight and disorders in sperm motility and motion were found. In rodents, pre- and postnatal exposure to PBDE can cause neurobehavioral effects. Also in humans disturbances in thyroid hormone system, weight of reproductive organs and concentrations of sex hormones associated with PBDEs serum concentrations were found. Exposure to PBDEs during pregnancy may lead to slower mental and psychomotor development in infants. In this paper the results of previous animal a nd human studies are reviewed.

Opis:
Rice is the main crop in the irrigated agriculture zone of the Aral Sea region of Kazakhstan. The rice culture is hygrophytic and requires a large amount of irrigation water as well as a washing irrigation regime, which contributes to the leaching of salts from rice paddies. In the rice crop rotation, an active process of salt accumulation in the soil occurs after the rice stage. This happens because of the secondary soil salinization. The aim of the research was to study the salt tolerance and soil desalting properties of the new varieties of melilot during cultivation in the rice crop rotation in the irrigated area of the Aral Sea region of Kazakhstan. The research conducted in the Research and Development Center for the Microbiology and Virology showed that the cultivation of the “Arkas” variety of white melilot and the “Saraichik” variety of dentated melilot on saline soils in the rice crop rotation in the Aral Sea region of Kazakhstan leads to the soil desalination. According to the results of the research, the content of salt solid residue in the arable layer (0–30 cm) was lower under the “Saraichik” variety of dentated melilot than under the “Arkas” variety of white melilot. The level of groundwater rises and the process of salinization intensifies during the cultivation of crops. The transition from subsaline soils to the soils with a high degree of salinization occurs. The rates of development and growth are slow during the first year in melilot varieties; however, despite the low indicator values, the harvest results in a single mowing were high (229–309 kg/ha of herbage and 57.2–74.3 c/ha of hay). The “Saraichik” variety has large leaves, branching stems and high foliage. The “Saraichik” dentated melilot has a beneficial feature. This variety is able to use groundwater with high salt content more efficiently for its growth and development. It should be noted that the melilot yield of the first year was harvested in the region without irrigation, and it grew using the moisture reserve accumulated in the soil during the previous year from the watering of the previous culture, i.e. rice. Therefore, the results of the study demonstrated that “Arkas” white melilot and “Saraichik” dentated melilot are promising cultures that can be introduced into the rice crop rotation in the areas with saline soils in rice field systems of the Aral Sea region of Kazakhstan.

Opis:
Parity progression ratios (PPR's) have been extensively described in literature on demography and have played an important role in fertility, unlike the idea of calculating projected parity progression ratios proposed by Brass (1985). However, we decided to use this method in our paper to analyse future fertility trends, firstly by assessing age-specific parity progression ratios for women in childbearing ages, and then by comparing these ratios with ratios at the end of women's reproductive life, as well as by comparing the latter with the completed PPR's. More specifically, the aim of this study is to adopt a modified Brass method to calculate the projected parity progression ratios using the age-period fertility data sourced from the Human Fertility Database (HFD). We progress to use the observed and predicted age-specific PPR's to examine parity progressions in Poland as a case study.

W Polsce na przełomie XX i XXI w. można zaobserwować istotne zmiany w przebiegu procesu reprodukcji ludności, dlatego celem podjętego postępowania jest rozpoznanie zmian we współczynnikach dzietności kobiet w miastach 100-tysiecznych i większych według liczby mieszkańców i regionów w latach 1999-2012 oraz kierunku i kształtu tendencji rozwojowych analizowanych współczynników. Dla zrealizowania postawionego celu zastosowano metodę indeksową i dekompozycji szeregów czasowych. Dzietność została określona przez współczynniki dzietności ogólnej kobiet. Analiza wykazała zmiany w kształtowaniu się poziomów współczynników dzietności w poszczególnych grupach miast ze względu na liczbę mieszkańców i regionów statystycznych. Największe zmiany zauważono w grupie miast 500-tysięcznych i większych według liczby mieszkańców oraz w miastach regionu północnego i południowo-zachodniego. Tendencje zmian najlepiej opisują we wszystkich stosowanych podziałach funkcje wielomianu trzeciego stopnia.

For fulfilling the put purpose an index method and a method of the disintegration of time series were applied. The fertility was determined by coefficients of the total fertility of women. Analysis demonstrated changes in the forming oneself of levels of rates of the fertility in individual groups of cities on account of the population and statistical regions. The biggest changes were noticed in the group of cities of 500 thousand and more residents and in cities of the north and south-western region. Tendencies of changes best are describing third degree functions of the polynomial in all applied divisions.

Opis:
Together with fast economic growths in recent decades and subsequent environmental pollutions, fertility rates have declined dramatically in China. Considering fertility intention is an essential predictor for fertility rate, we examine the effect of air pollution on fertility intentions in China. Using data from the China General Social Survey (CGSS) collected in 2010 and 2013, we find a negative and significant impact of air pollution on people’s fertility intentions. More importantly, after we restrict the sample to people who have been living in current places for a long period of time, the estimated effect of air pollution decreases but remains significant, indicating existence of endogeneity of air pollution on fertility intentions. For the government to take measures to raise fertility rates in China, it is important to take into account the factor of air pollution.
Wraz z szybkim wzrostem gospodarczym w ostatnich dziesięcioleciach i późniejszym zanieczyszczeniem środowiska, wskaźniki dzietności w Chinach dramatycznie spadły. Biorąc pod uwagę, że intencja płodności jest podstawowym predyktorem współczynnika dzietności, badamy wpływ zanieczyszczenia powietrza na intencje dzietności w Chinach. Korzystając z danych z China General Social Survey (CGSS), zebranych w 2010 i 2013 r., wskazujemy na negatywny i znaczący wpływ zanieczyszczenia powietrza na intencje ludzi w zakresie płodności. Co ważniejsze, po ograniczeniu próby do osób, które mieszkają w obecnych miejscach od dłuższego czasu, szacowany wpływ zanieczyszczenia powietrza maleje, ale pozostaje znaczący, wskazując na istnienie endogeniczności zanieczyszczenia powietrza na intencje płodności. Stwierdzamy, że aby rząd mógł podjąć działania mające na celu podniesienie współczynnika dzietności w Chinach, konieczne jest uwzględnienie czynnika zanieczyszczenia powietrza.

Opis:
The article is a follow-up and an extension to previously published papers by Holzer-Żelażewska & Holzer (1997) and Holzer-Żelażewska & Tymicki (2009). Fristly, we have added new cohorts to the cohort analysis based on the individual data from births registration for the years 2009–2015. Secondly, we have extended the scope of the study by taking into account the context of postponement and recuperation to analyses of cohort fertility of Polish women. The approach applied to the fertility postponement and recuperation on the cohort data refers to the method which was originally proposed by Frejka (2011) and Lesthaeghe (2001) and further developed by Sobotka et al. (Sobotka et al., 2011). This method allows for calculation of fertility postponement and recuperation measures with respect to a benchmark cohort chosen as the one that first experiences an onset of the increase in the mean age of motherhood at first birth. The results show the remarkable changes in the fertility patterns in Poland. The main driving forces behind the change in fertility patterns in Poland are related to the postponement of first births along with a relatively good recuperation. The magnitude of recuperation for Polish cohorts dropped significantly for second births and was almost non-existent for third and higher births. Therefore, the pattern of fertility in Poland observed till 2015 could be characterized by postponement and recuperation of first births along with a significant decrease in second births with perpetual postponement of third and higher births.

Opis:
Jednym z podstawowych mierników płodności kobiet jest cząstkowy współczynnik (drugiej kategorii) płodności ogólnej kobiet rodzących dziecko kolejności p. Szacowanie współczynników płodności możliwe jest na podstawie bieżącej rejestracji ruchu naturalnego ludności. Większym problemem, z uwagi na ruchy wędrówkowe ludności, jest jednak uzyskanie oszacowań dla danych regionalnych oraz dla kohort, które nie były objęte jeszcze rejestracją bieżącą. Estymacja współczynników płodności odbywa się dla wielu szczegółowych przekrojów. Sprawia to. że nawet przy kilkusettysięcznej ogólnopolskiej próbie współczynnik wyznaczany jest dla stosunkowo niewielkiej domeny kobiet urodzonych w danym roku i zamieszkujących w określonym województwie. Rozkład płodności kohorty kobiet w czasie jest rozkładem o silnej prawostronnej asymetrii i o zazwyczaj gładkim przebiegu. W wyniku badania reprezentacyjnego uzyskany rozkład będzie jednak zaburzany na skutek losowego mechanizmu doboru jednostek. Tym samym pojawia się konieczność wygładzenia rozkładu tak, aby zniwelować wpływ składnika losowego w ostatecznym obrazie rozkładu płodności. Celem pracy jest weryfikacja możliwości zastosowania metod wygładzania dla tablic płodności i ocena wpływu wygładzania na efektywność estymacji.

Opis:
NaProTECHNOLOGY is a new field of medicine specializing in the promotion of human procreation. Its foundation is a teaching system called the Creighton Model Fertility Care System. It is based on the ability to observe and record biological biomarkers, enabling spouses to recognize and understand the naturally occurring cycle of fertility and infertility. The spouses can use their acquired knowledge both for achiving pregnancy and avoiding pregnancy. The system also enables them to broaden their knowledge to better understand sexuality and deepen their mutual love. It also plays an important role in diagnosing and treating reproductive health according to the natural cycle of women. NaProTECHNOLOGY is involved in building a "new culture of life" through integral concern for human fertility by restoring natural procreation and respecting the principles of responsible parenthood.

Opis:
This research examines the gendered consequences of the international low-fertility agenda, as it has been realized in an era of a globalized labor market, by documenting some of the ways that families in rural Bangladesh have shifted filial responsibilities between daughters and sons. Such shifts are occurring in a context of new demographic and economic realities that have been largely shaped by national policies and pressure from international organizations. Using qualitative interview data, this study examines how, in the context of declining family size, male labor migration, and increasing life expectancy, women and girls are expected to take on a larger share of filial responsibilities. While sons’ responsibilities narrow to include economic contributions through wage earning and remittances, expectations for daughters are expanding and may include earning a wage, as well as caring for both natal and marital relatives. This paper also seeks to problematize the conflation of fertility decline, poverty reduction, and women’s well-being by arguing that women’s empowerment is not a natural result of smaller families.

Opis:
In the last 20 years the United States, in contrast to European Union countries, has not experienced a reduction in fertility. The socio-economic determinants of fertility of women are widely discussed in the literature. Fertility of women in the United States is determined by many factors, including religion, education, income, place of birth, ethnicity, immigration status, marital status and age. The presented paper reviews results of selected studies published in the last 40 years in demographic journals and focuses on the relationship between religion, income, education and immigration status and fertility of women in the United States.

Opis:
Soil is essential for food production, and there is need practice sustainable soil management. This study was aimed to evaluate physical and chemical properties of soils and their management in three farming communities; Sangasumi (SGS), Gangkoen (GGK) and Gangbuen (GGB) of Southern Adamawa State, Nigeria. The intent is to encourage optimum land use planning and increase the efficiency in the use of soil resources. In the work, a digital Terrain Model (DTM) was generated from the map of the study area, and three elevation ranges were identified; 660-780m - representing the upper-slope in SGS, 540-660m - representing the middle-slope in GGK and 420-540m - representing the lower-slope in GGB, respectively. Three slope positions were delineated using the Geographic Information System (GIS) and their coordinates were obtained by means of a Handheld Geographic Positioning System (GPS). Three profile pits were dug on each of the locations and soil samples were collected in each of the identified horizon of the pits. Standard laboratory procedures were then used to determine soil physical and chemical properties. Herein, results for particle size analysis indicated that the soils were predominantly sand, ranging between 51% to 91% across the pedons and %sand was positively correlated with bulk density. Moreover, soil pH in each sample was slightly acidic to neutral (6.1-6.5 to 6.6-7.3), while organic carbon and total nitrogen levels were low (<1%, <0.15%) and available phosphorus levels were medium (10-20ppm). In contrast, magnesium was high (>1), sodium recorded up to 0.60cmol/kg, potassium was also high (>0.3) and %base saturation were generally medium to high (50-80 to >80). Results suggest the soils have potentials for arable farming. However, soil erosion hazards had affected parts of the fields; this lead to reduction in soil fertility and crop yields. Addition of organic and inorganic fertilizers and control of soil erosion will greatly improve soil fertility losses and increase crop yields.

The main aim of the article is to analyze the demographic situation of the Czech Republic and to present the prospects for Czech demography in the coming years. The text is divided into sections related to the most important components of the demographic situation - population size and factors that influenced it in the past (e.g. the baby boom phenomenon), live births, the structure of the aging society in the Czech Republic (there are more people aged 65+ than in the age group 0-14), deaths (caused largely by cancer and cardiovascular diseases). An important part of the analysis is the problem of external migration. The article was prepared on the basis of data from the Statistical Yearbook (Statisticka Rocenka Česke Republiký), published by Český Statistický Úřad (CSU). The text ends with conclusions and recommendations on demography. The author believes that the demographic problems of the Czech Republic are part of the overall demographic problems of the European Union, such as the low fertility rate (TFR), which is still far from the simple replacement of the generations. The result is an ageing European population, which will have a negative impact on the economy, social systems and external policies.

Opis:
Introduction: Ulcerative colitis is one of the most interesting nosological entities of gastroenterology and internal medicine. This chronic autoimmune disorder of the digestive system, along with Crohn's disease, is a type of idiopathic inflammatory bowel disease. It mainly affects people during their peak reproductive age, i.e., 15 to 30 years old. It is characterized by diffuse mucosal inflammation of the large intestine, which is limited to the colon and shows alternating periods of exacerbations and remissions. Purpose: To review the world literature regarding the impact of the disease on fertility, the course of pregnancy, and consecutively, the outcome of pregnancy.Materials and methods: An extensive review of the recent national and international literature in electronic databases (Pubmed, Google Scholar) and in scientific journals was accomplished through the use of appropriate keywords. Results: The majority of women will have a chance of conceiving. For about 25% of them, conception will be achieved in the course of the disease and it will progress normally, resulting in a healthy fetal outcome. Infertility only occurs among men while they are taking medicines, whereas among women it occurs after surgery for ileoanal anastomosis. During periods of flare-ups, there is a possibility of spontaneous abortion, premature labor and birth of an infant with low birth weight. The majority of pharmaceutical formulations can be used safely both before and after pregnancy without causing any birth defects.

Opis:
Polska, podobnie jak cała Europa, doświadcza kryzysu demograficznego. Rozmiary, natężenie i rozmieszczenie zjawisk depopulacyjnych jest przestrzennie zróżnicowane, zarówno pomiędzy poszczególnymi krajami europejskimi, jak i wewnątrz poszczególnych państw. W Polsce obszarem o najgorszych warunkach wzrostu liczby ludności jest województwo opolskie, zwłaszcza w zakresie dzietności kobiet i skali migracji zewnętrznych. Splot tych zjawisk (a także uniwersalny proces starzenia się populacji) prowadzi wprost do zapaści demograficznej. Świadomość tego zagrożenia spowodowała opracowanie specjalnego programu „naprawczego” wkomponowanego w Regionalny Program Operacyjny na lata 2014-2020, z instytucjonalnym i finansowym wsparciem niezbędnych działań.
Poland, likewise the whole Europe, is experiencing demographical crisis. Size, intensity and placement of depopulational phenomenas are spatially differentiated, as well as among particular European states, but also inside particular countries. Opole Province is the region with the worst growth conditions for population in Poland – especially in women fertility and outside migration scale scope. Confluence of those events (together with universal process of population’s aging) leads straight to demographical deprivation. Awareness of this threat caused that the special “repairing” program was developed, which was incorporated in Regional Operational Program for the period 2014-2020, with institutional and financial support of essential actions.

Recenzowana monografia autorstwa lubelskiej teolog i psycholog, Urszuli Dudziak, stanowi interdyscyplinarne stadium familiologiczne i pastoralne eksplorujące trzy obszary badawcze o pryncypialnym znaczeniu dla duszpasterstwa rodzin: „płciowości i seksualności”, „płodności i prokreacji”, „starzenia się i umierania” człowieka. Celem podjętych w rozprawie badań literaturowych było wypracowanie integralnej syntezy antropologicznej ludzkiego biologizmu rozpatrywanego w ścisłym związku z pozostałymi sferami osobowymi. Autorka kompetentnie posłużyła się metodą monograficzną, wykorzystując metodologię badań teoretycznopoznawczych i szeroko czerpiąc z wyników nauk pomocniczych teologii pastoralnej. Całość opracowania jest dobrym przykładem personologii pastoralnej, która założenia chrześcijańskiej antropologii personalistycznej przekłada na język praktyki pastoralnej Kościoła katolickiego ukierunkowanej na integralny rozwój osoby ludzkiej w trzech szczególnych etapach jej życia: poczęcia i narodzin, aktualizacji zdolności prokreacyjnych i przekazywania daru życia, starzenia się i umierania.
The reviewed monograph by Urszula Dudziak, a theologian and psychologist from Lublin, is an interdisciplinary familiological and pastoral case study exploring three research areas of paramount importance for the pastoral care of families namely “gender and sexuality”, “fertility and procreation”, and “ageing and dying” of the human being. The aim of the literature research undertaken in the dissertation was to develop an integral anthropological synthesis of human biologism considered in close relation to other personal spheres. The author competently used the monographic method, utilising the methodology of theoretical-cognitive research and drawing extensively on the results of the auxiliary sciences of pastoral theology. The study as a whole is a remarkable example of pastoral personology which translates the assumptions of Christian personalist anthropology into the language of the pastoral practice of the Catholic Church aimed at the integral development of the human person at three particular stages of his or her life namely conception and birth, actualisation of procreative abilities as well aspassing on the gift of life, ageing and dying.

The objective of the study was to determine the effect of replacing triticale (high rumen degradable starch) with maize grain (low rumen degradable starch) during the transition period and the first 120 days of lactation on metabolic and hormonal profile indices, milk production and fertility performance in cows. Forty-eight Holstein-Friesian dairy cows were divided into 4 groups: TT (2.5 kg triticale grain/cow per day supplemented from 14 days prepartum to day 120 postpartum), TM (2.5 kg triticale grain/cow per day supplemented from day 14 before parturition to calving, and then 2.5 kg maize grain to 120 days of lactation), MT (2.5 kg maize grain/cow per day supplemented from day 14 before parturition to calving, and then 2.5 kg triticale grain to 120 days of lactation), MM (2.5 kg maize grain/cow per day supplemented from 14 days prepartum to day 120 postpartum). Blood samples were collected 3 weeks and 1 week before calving and on days 14, 56 and 70 of lactation, and they were analyzed in terms of concentrations of glucose, insulin, leptin, insulin-like growth factor I, nonesterified fatty acids, triglycerides, cholesterol, blood urea nitrogen and activities of aspartate aminotransferase and gamma glutamyl transpeptidase. Milk samples were collected twice a day at weekly intervals and analyzed for fat, protein and lactose. Milk yield and individual dry mater intake were recorded at weekly intervals. Body condition was estimated 3 weeks before calving, on parturition day and on days 14, 56 and 120 of lactation. Replacing triticale grain with maize grain in the transition period and during lactation positively affected fertility of lactating cows. An increased first service conception rate and shortening of the days open period was observed in MM and TM groups in comparison to those found in group MT (P ≤ 0.05). The lowest number of services per conception was recorded in groups MM and TM (P ≤ 0.05). Although the impact of milk production and the most of the blood indices were not significantly affected by this treatment, the results of the study suggest that maize grain in the transition period and lactation might be a more effective energy source for dairy cows than triticale grain.

The shape of the contemporary family keeps changing in both these countries, but the speed of changes is different. In Poland, changes in family formation have occurred much more slowly than in Spain, where the family is not only heterosexual marriage, but also homosexual marriage.

Anthocyanin spot on the leaves of red clover is inherited independently of light spot and uniform leaf colour. The gene determining anthocyanin spot is probably localized on the other chromosome than the gene determining light spot on the leaves. A short flower tube is also determined by a single recessive gene of a pleiotropic action. It simultaneously causes reduction of pistil style, thickening of the endothecium layer in anthers - entails their indehiscence, pollen grain-agglutination and often deformation, no division of part of pollen grains into a vegetative and generative cells as well as germination of single grains in pollen sacks. The changes in the structure of endothecium and pollen grains cause almost complete male and female infertility of plants with short flower tubes.

The issues of soil fertility preservation are relevant in all countries of the world. Concrete actions, technological and organisational solutions allowing to overcome this complex and continuous phenomenon by using exclusively agroengineering approaches are proposed. The preservation of the structure of agricultural soils requires urgent adoption of technological and organisational decisions in the following areas: maximum limitation of immobilisation of nitrogen in the soil after introduction of organic residues into the soil; development of technological methods and tools for the soil cultivation, aimed at loosening the surface layer of the soil with a minimum area of its contact with the airborne environment; improvement of the fundamentals of aggregation of agricultural machines, taking into account the maximum permissible slipping of wheeled energy facilities at the level of 15%, and a conceptual approach to their ballasting with respect to the requirements of the tire ecophilicity; application of a soil structure indicator when determining the ploughing frequency by means of ploughs with skimmers or their twotier analogs; wide practical application of the controlled traffic farming system; adoption of a legislative document on specific conformity of the land users for the level of soil fertility for agricultural purposes.

BIRTH REGISTRATION DATA
Opis:
Various aspects of Polish migration to the United Kingdom (UK) have been explored by academic and other researchers to date. However, analysis of the reproductive behaviour of Polish migrants in the UK is still scarce, despite the fact that children born to Polish mothers constitute a large and growing share of all children born in the UK. In this paper the author examines fertility trends of Polish migrants through an analysis of birth registration data. The first part of the paper reviews relevant hypotheses relating to migrants’ fertility behaviour. Literature on children to Polish migrants in Germany, Sweden and the UK is also reviewed. The second part of this paper draws on analysis of births to Polish migrants in the UK and provides an overview of birth trends for this migrant group. The author shows that the proportion of births to Polish mothers is increasing in the UK and that the increase in these births has been substantial in all UK countries. Analysis of the data also shows that an increasing proportion of children are born to two Polish parents and that Polish fathers are not likely to have children with non-Polish partners. In the final part of the paper the author discusses these trends and provides potential socio-economic implications of Polish migrants’ reproductive behaviour for demographic trends, the labour market and public services.

Opis:
Being more sensitive to economic fluctuations, childbearing postponement increased during the second demographic transition and was accompanied by a moderate decline in the number of children per woman and the progressive rise of mother’s age at first birth. Under the hypothesis that recessions have a marked influence on population dynamics, the present study investigates spatial changes in mother’s age at birth in Greece with the aim to assess the differential impact of economic crisis along the urban-rural gradient. The percent composition of births by mother's age class – considered a gross indicator of fertility under a changing socioeconomic context – was studied at 4 spatial scales (the whole country, administrative regions, prefectures and metropolitan areas or specific economic districts) over an economic cycle from expansion to recession (1980–2016). While stimulating childbearing postponement observed since the early 1980s, empirical results of this study indicate that the 2007 recession was quite neutral on fertility trends in Greece, consolidating the traditional divide between urban and rural areas.

Opis:
Changing gender roles are increasingly considered as a driving factor of both fertility decline in European countries and its recovery in some of these countries. The fertility decline is attributed to the first stage of the gender revolution when increasing women’s labour force participation is accompanied by some progress in gender equality in the public sphere while in the family life a gender asymmetry remains. During the second stage of the gender revolution the progress towards new roles of men and women in the private sphere takes place – they both are considered as economic providers and careers and share work and family responsibilities (e.g. McDonald 2000b, Goldscheider, Bernhardt, Lappegård 2015, Esping-Andersen, Billari 2015). The article compares on-going changes in gender roles in Poland and Norway, two countries which are at different stages of this process, and their interplay with fertility (mean number of children and intensions about the second and third child). Attitudes towards gender equality are studied by taking into account views on this issue on one side and sharing care and housework on the other. Data come from the first round of the Generations and Gender Survey. The study has been performed for respondents aged 20–44, living together with a partner and children under 14 years of age. The descriptive analyses showed that Poles are not only less advanced in gender role changes in two gender dimensions studied: their views on gender roles are more traditional than Norwegian ones, women’s share in family duties is higher contrary to men who contribute less to family responsibilities than women and men in Norway. There is also a higher variation of views and practices among Poles. In Poland and Norway, egalitarian men participate more in family duties than those who declare traditional views, while egalitarian women are less burdened by home work and care. However, in Norway there is remarkably more egalitarian women with low and medium share of domestic duties in parallel to more numerous egalitarian men who take a great share of family responsibilities. More egalitarian respondents have fewer children than the traditional ones in both countries. However, the mean number of children among this group of respondents in Norway is higher than in Poland. Moreover, women in both countries are less inclined to declare intensions to have a second or third child when they participate more in care and domestic duties. This relationship has been found for men in Norway as well.

Opis:
Modern technologies make it possible to obtain a lot of diverse information about the soil properties using satellite images, but field studies are also required to create or refine digital soil maps. To create a digital soil map scaled 1:25 000 in 2016, a classical field study was conducted with the laying of soil sections in places with the same coordinates as in the mapping of 1982. It allowed to carry out retrospective monitoring of transformation of morphogenetic and agrochemical properties of soils of the southern forest-steppe of the Republic of Bashkortostan (Russia) for the 34-year period of farm use. Thus, the correction and digitization of the soil map allowed to establish that arable land occupies 69.792 ha (67.9%) in the structure of agricultural land (102 811 ha). The monitoring showed deterioration of the main characteristics of arable soil fertility: the diminishing of humus-accumulative horizons, significant decrease of humus content (p ≤ 0.05), a small but reliable acidification of the medium reaction and reducing labile phosphorus. Losses of organic matter occurred mainly in the most fertile soils; their proportion decreased from 55.9% of the total area of agricultural land to 12.4%.

Opis:
The intention of the analysis is to indicate socioeconomic determinants of fertility for Poland. The analysis is made with respect to the labour market structures, living conditions, gender norms and appreciated values. Logistic regression models of first and second birth order were used, based on the 2006–2010 Polish Labour Force Survey data. Despite registered rebound in TFRs, there is no evidence to prove the Hypothesis of Fertility Positive Turn holds for Poland. Incompatibility of paid-work and childcare points the premises of the positive turn have not been fulfilled yet. Instead, the stability hypothesis seems to have some evidence as models show significant relation of marital status, household status and the labour market situation of the partner to fertility.
Niniejsza analiza ma na celu wskazanie socjoekonomicznych determinant dzietności dla Polski. Analiza uwzględnia wpływ struktur rynku pracy, warunków życia, podziału ról ze względu na płeć i cenionych wartości. Zaprezentowano modele regresji logistycznej urodzeń pierwszego i drugiego dziecka, przygotowane na podstawie danych BAEL za lata 2006–2010. Pomimo zaobserwowanego odbicia w poziomie współczynnika dzietności, nie ma podstaw, by sądzić, że hipoteza o pozytywnym odbiciu współczynnika dzietności (the Hypothesis of Fertility Positive Turn) jest spełniona dla Polski. Trudności w łączeniu pracy zarobkowej i opieki nad dzieckiem wskazują, że przesłanki tej hipotezy nie zostały jeszcze spełnione. Wydaje się natomiast, że hipoteza o stabilizacji (the Stability Hypothesis) lepiej tłumaczy decyzję o urodzeniu i wychowaniu dziecka, jako że modele wskazują na istotną statystycznie relację między dzietnością a stanem cywilnym, faktem zamieszkania w domu rodziców i statusem męża/partnera na rynku pracy.

Opis:
Soil acidification, fertility depletion, food insecurity, and environmental pollution all are consequences of the extensive use of chemical fertilizers (CF) in intensively managed plantations. Recent studies have shown that incorporating organic manure (OM) to partially replace CF can help to maintain productivity and soil health. There are no reports on integrated fertilizer management of Zanthoxylum armatum, for optimal ecological services and economic profitability. A pot experiment with Z. armatum was performed to investigate the possibility of incorporating OM in reducing CF use, enhancing soil fertility, and increasing plant growth. For this, seven treatments were designed: NPK, PK, NP, NK, OM, MNPK (50%NPK+50%OM), and control (CK, no fertilizer application). The results showed that NPK application significantly (P < 0.05) increased plant growth, soil nitrate-N, ammonium-N and available K compared to CK. However conventional CF application induced soil acidification. OM application raised the soil pH from 5.50 (CK) to 6.58 and significantly enhanced soil fertility by increasing alkali-hydrolysable N (2.3 times), ammonium-N (1.4 times), available P (4.3 times), the activity of invertase (1.5 times), catalase (2.8 times), acid phosphatase (1.5 times), and count of soil culturable microbes (2.9 times) compared to CK. Conversely, sole OM application did not result in optimum plant growth. Integrating OM with NPK (MNPK), on the other hand, not only provided the highest growth comprehensive value (0.84), but also substantially higher soil fertility comprehensive value (0.71) than traditional CF treatments. Correlation analysis also indicated a positive and significant correlation between soil microbes, enzyme activities and available nutrients. Therefore, OM+NPK could be an optimum measure to get maximum benefits regarding soil fertility, growth of Z. armatum, fertilizer savings and sustainable agroecology.

Opis:
Обсуждая пространственную дифференциацию рождаемости, обычно внимание сосредоточивается на сопоставлении изменяющихся величин коэффициента теоретической рождаемости или коэффициента рождений. В статье была предпринята попытка проверить постоянность расположения регионов в отношении к уровню рождаемости и определить на основе распределения рождаемости, в каких возрастных группах выступают самые большие различия между административными единицами занимающими крайние позиции в отношении к рождаемости. Анализ — несмотря на высокую лабильность воеводств — выделил стабильную группу регионов с самой низкой рождаемостью (опольское и нижнесилезское воеводства). Одновременно было подтверждено, что несмотря на ассимиляцию распределения рождаемости повышается дифференциация склонности иметь детей в крайних группах возраста — женщины-подростки и женщины в возрасте выше 35 лет.
Mówiąc o przestrzennym zróżnicowaniu dzietności, z reguły uwaga skupiona jest na porównaniu zmieniających się wartości współczynnika dzietności teoretycznej lub współczynnika urodzeń. W artykule podjęto się sprawdzenia stałości uporządkowania regionów z punktu widzenia poziomu dzietności oraz ustalenia na podstawie rozkładów płodności, w jakich grupach wieku występują największe różnice pomiędzy jednostkami administracyjnymi zajmującymi ekstremalne pozycje pod względem dzietności. Z analizy —mimo wysokiej labilności województw — wyłoniła się stabilna grupa regionów o najniższej dzietności (województwa opolskie i dolnośląskie). Jednocześnie stwierdzono, że pomimo upodabniania się rozkładów płodności rośnie zróżnicowanie skłonności do posiadania potomstwa w grupach wieku ekstremalnych — kobiet nastoletnich oraz tych po 35. roku życia.
While spoken about spatial distribution of total fertility rates (TFR), generally attention is paid to changes in level of (total) fertility rates and/or birth rates. In the paper attention is paid to stability of ranking of Polish regions defined in terms of TFR values, and to changes in fertility distribution among regions with extreme TFR levels. Age groups with the largest fertility differences are sought. Despite high liability group of "losers" could be found (regions with low TFR - Opolskie and Dolnośląskie Voivodships). In spite of fact that fertility distribution are becoming more and more similar, growing differences are observed when analyzed fertility of teenagers and females aged 35+

Opis:
The aim of this study was to evaluate the fertility response of dairy cows with anovulation type I on repeated low doses of GnRH agonist buserelin. The study was conducted on 83 anovulatory and 60 cyclic Polish Holstein Friesian cows. Anovulation type I was defined as small ovaries with follicles of ≤ 5 mm in diameter and without corpus luteum on two examinations in a 7-10 day interval between 50–60 days after parturition. Cows from the experimental group (n=58) received 0.4 μg of buserelin i.m. once a day for 5 consecutive days. Cows from the negative control group (n = 25) received saline. Sixty cyclic cows receiving no treatment served as positive controls. Intervals from calving to estrus and from calving to conception, pregnancy rate 30-35 days and 260 days after AI, and pregnancy loss were calculated. The anovulatory cows had a substantially prolonged calving to conception interval, decreased pregnancy rate and increased pregnancy loss and culling rate compared to cyclic herd mates. The average calving to conception interval was significantly (p<0.05) shorter in treated cows compared to non-treated anovulatory cows (153.7 days vs 209.3 days). In conclusion, repeated low doses of GnRH analogue buserelin led to a significant shortening of calving to conception interval. More clinical trials are needed to determine the practical usefulness of this method for the treatment of anovulation type I in dairy cows.

Progressive decline in fertility and sperm quality has been reported over the last few decades, especially in industrialized nations. It has been proposed that exposure to factors that induce damage in DNA of spermatogenic cells may significantly contribute to impaired fertility. Here, the 32P-postlabelling method was used to analyze the levels of bulky DNA adducts in sperm cells in a group of 179 volunteers, either healthy subjects or patients with an impaired fertility. The levels of DNA adducts were 1.35-fold higher in the infertile group as compared to healthy individuals (P = 0.012). Similarly, a significant negative correlation between the levels of DNA adducts and measures of semen quality (sperm concentration and motility) has been observed (P Ł 0.001). In addition, the levels of bulky DNA adducts in sperm cells positively correlates with amounts of leukocytes in semen, which were significantly higher in semen of infertile subjects.

Reciprocal translocations, very frequently identified in pigs, are the cause of fertitlity decrease. The aim of this work was to provide an objective assessment of the real effect of reciprocal translocation (7;13) on the fertility of carriers and associated economic effects. The experiment has shown that fertility, expressed as a mean litter size, decreased by 48% in comparison to that of the control group. On the basis of simulation account, financial losses incurred a translocation - as a result of using carrying boar in a commercial herd were estimated at about 8,000 USD for natural mating and at about 162,000 USD for artificial insemination. The results obtained show the need for introducing a system for cytogenetic control of boars producing small litters into the Polish swine improvement programme.

Postponing motherhood is a widespread phenomenon across developed countries, however only few studies look into very late motherhood in post-socialist countries using individual level data. In this study, I look at the context of the first childbirth in Poland in the midst of the political transformation of 1989. Employing sequence analysis I reconstructed life trajectories of women who experienced the transition to adulthood during the late 1980’s and the early 1990’s and have just completed their fertility histories. Individual data from the 2011 GGS-PL and the 2011 FAMWELL Survey were used. Comparing paths of mothers’ lives, I searched for differences in educational, professional and conjugal careers between women who gave birth before the age of 30 and after the age of 35. The results show how various life careers crisscross over the life course leading women to late motherhood.

Opis:
The article presents both theoretical and empirical aspects of studies on fertility intentions in the context of factors shaping fecundity. In most contemporary societies couples declare their preference for two children. These declarations stand in opposition to registered total fertility rates, both period and cohort rates, which rarely reach value of 2 in Europe. The gap between fertility intentions and their realization might be partially explained by the impact of reproductive ageing (biological factors) which may play an increasingly significant role due to postponement of childbearing. A natural pattern of a decrease in fecundity over age might influence on reproductive outcome of women who postpone to conceive a child, and consequently results in an increased risk of involuntary childlessness or lower parity progression ratios. The data coming from the Generations and Gender Survey in Poland (GGS-PL) makes it possible to check the main hypothesis about an age-specific decrease in fecundity, which is manifested by a prolonged waiting time to pregnancy. The data were collected via the retrospective questions included into the GGS-PL questionnaire. Results show that there is a significant increase in waiting time to pregnancy among women older than 34 years. This finding supports theoretical predictions concerning the age-related decrease in fecundity. Its relevance is discussed by referring to explanations of the gap between fertility intentions and completed fertility in terms of voluntary and involuntary childlessness, as well as biological factors related to reproductive ageing.

Opis:
The paper aims to show the way in which pension systems affect fertility rates. The author outlines the history of pension systems and traces changes in fertility. The article includes a brief overview of demographic theories and tells the reader why these approaches are inadequate in explaining fertility trends. In his analysis, Zwierzchowski makes use of the overlapping generations model (OLG) to show why and under what circumstances pensions may discourage people from having children. After further theoretical research, the author concludes that the negative influence of pension systems on fertility could be neutralized by the introduction of a public assistance program targeted at parents. The costs of such a program could be covered by those who do not have children, Zwierzchowski says. While today’s welfare state systems cover some of the costs of bringing up children, it is unclear to what extent this assistance neutralizes the negative impact of pension systems on fertility, Zwierzchowski notes.

Due to the rapidly progressing demographic changes, the aging of the Polish society is becoming increasingly important challenge for the economics. One consequence of the growth in the number of elderly people in society is a greater demo-graphic burden, that without significant reforms may lead to a deterioration of the economic situation throughout the country. The aim of this article is to present four areas (health care, labor market, lifelong learning, family policy), which should address the most important changes, aimed at reducing the burden of aging population on the economy. Data published by the Central Statistical Office of Poland and literature studies were used to the analyze.

Opis:
Amongst various and diverse organisms, earthworms (Annelida: Oligochaeta) are the most important components of soil biota when it comes to soil formation and maintenance of soil structure and fertility. The presence of earthworms modifies the soil quality of the environment due to their burrowing and casting. This affects the activities of other organisms. Thus, they are also termed “ecosystem engineers”. However, while we begin to understand the role of surface casts, it is still unclear to what extent plants utilize subsurface casts. This work is a study of the floral community structure as influenced by surface cast so as to determine the functional groups of earthworms in the natural forest zone of Onigambari Forest Reserve. This reserve is located at latitude 07°25’N and longitude 3°53’E within the low and semi-deciduous forest belt of Nigeria. It is divided into two: natural and plantation forests. Herein, the simple random sampling technique was used to select 10 geo-referenced plots (15m × 15m each). Three 1.0m × 1.0m square quadrats were randomly laid on each plot to give 30 sampling points surveyed for data collection. Data were collected on floral composition, relative importance values (RIV), earthworm composition and diversity, and physicochemical components of the soil. Twenty eight herbaceous plants were enumerated. Andropogon gayanus had the highest relative importance value (RIV) of (20.499), while Acroceras zizanoides and Platostoma africanum had the least RIV (1.1782) amongst other four. Seven earthworm species were enumerated, with Eisenia fetida having the highest RIV (28.571), while Octoclasion cyaneam and Lumbricum rubellus had the least. The species richness of earthworms was high (0.8061) and evenly distributed (0.8405), but with a low diversity (H’ = 1.772). There are two functional groups of earthworm in the natural forest zone, seven were surface dwelling, while only Lumbricus terrestris was sub-surface dwelling. The health of flora and soil of the natural forest zone of Onigambari forest reserve is low. Prevention of outside influence on the forest zone, seeding and deposition of organic waste matter to the soil are strategies that would enhance abundance and diversity of earthworms in the natural forest zone.

Opis:
A survey on the role of soil organic matter (SOM) in tropical soil productivity was carried out with the objective of highlighting on the effects and benefits of organic matter on soil biophysical chemical properties and yield of crops in the tropics. It was revealed that tropical soils are inherently low in fertility due to predominance of kaolinitic clays. The soils are low in CEC, OM, available P and base saturation. Inorganic fertilizers are scarce and costly in addition to negative effects on soil causing acidification and induced micronutrients deficiencies. Organic matter contain a wide range of macro and micro nutrients. On mineralization, these nutrients are released, in addition to contributing of organic matter to the soil. This manure also improves physical properties and ultimately increase crop yield on a sustainable basis.

Opis:
According to literature of the problem, the disturbances of reproductiveness of human in various parasitic infections are discussed. The mechanisms disturbing the proper functioning of the hosts's reproductive system are not sufficiently understood. They may remain in association not only with a direct or indirect effect of the parasite on the host's endocrinal glands and sexual organs, but also with the host's overall reaction to stress or toxic influences. Parasite's activity may lead to abortion or a significant decrease in fetal body weight. Embryo or fetus may be also damaged in an intrauterine infection.

This article aims to identify the impact of labour market variables on fertility and family decision‑making in Poland. The paper begins with a general overview of an effect of the increased labour market participation of women on family formation. The second section briefly examines the influence of access to the labour market, high unemployment, labour migration and lower quality jobs on the family. Next, the author discusses conditions for work and family reconciliation in Poland (working hours, flexible forms of employment, full or part-time work). The article concludes with a brief information on how Poles perceive potential obstacles to parenthood related to the labour market.

Opis:
The observed decline in fertility in developed countries raises the question about the possibility of implementing a pronatalist government policy. In particular, possible policies involve modification of: income taxes, consumption taxes and the introduction of subsidies on children. The effectiveness of the listed fiscal policy instruments is debatable and it can be considered from theoretical or empirical point of view. The present work mainly focuses on the first approach, making a synthesis of existing economic theory in terms of the postulated effects of the fiscal instruments used to stimulate the number of children in families. The survey pinpoints two prevalent classes of models: the life cycle with taxpayer having children and multi-period overlapping generation models. The predictions of the models have been criticized, especially in the context of several simplifying assumptions undermining the practical utility of the results. Based on the literature review it can be seen that regardless of the context of redistribution of wealth, the fiscal instruments should affect the number of children in households. Additionally the effective pronatalist policy is not unique and in most cases, it should cover more than one fiscal policy instrument stimulating increase of birth rate.

Opis:
Potbelly style sculpture is a type of sculpture from the Middle or Late Preclassic Period found on the Pacific Coast. It consists of stone sculptures of the head alone, as well as the full body, which are characterized by chubby facial features and pudgy bellies. Th is style persisted during the Classic period in Teotihuacan and other areas, even though it was provided with more iconographic attributes. Mysteriously, the potbelly style disappeared in postclassical times. It is suggested that the physical features and quite possibly the meanings of the potbelly sculptures lived on in figures of monkeys during the Postclassic period as its physical representation and its symbolic complex were similar to those in earlier sculptures. The monkey was represented as potbellied and it was associated with fertility, excess, death, pulque, and possibly decapitation, among other aspects. Sexual excess was specially attributed to monkey, as is seen in codices which associate it with the transgressor and excrement, and depict it with a posture related to immorality. The negative side of the sign of the day of Ozomatli tended toward immoral sexual behavior. In the same way, the ape was conceived of as a women’s seductive and animal lover. This realm of sexual excess was shared by potbellied figures, at least in Teotihuacan and Mayan area.

drugie przejście demograficzne
Opis:
Od trzech dekad wskaźnik dzietności w Polsce utrzymuje się poniżej poziomu prostej zastępowalności pokoleń, a długoterminowe prognozy demograficzne nie zapowiadają rychłej poprawy w tym obszarze. Podejmowane w ostatnich latach w ramach polityki prorodzinnej działania okazały się mało efektywne. Dotyczy to również wprowadzonego w 2016 roku programu „Rodzina 500+”. Po początkowym wzroście wskaźnika dzietności w latach 2016-2017, ponownie nastąpił jego spadek. W artykule podjęto próbę odpowiedzi na pytanie, dlaczego program, definiowany jako pronatalistyczny, mimo zapowiedzi jego twórców, nie przynosi oczekiwanych rezultatów. Analizując przyczyny tego zjawiska, uwzględniono zarówno uwarunkowania demograficzne, wynikające m.in. z malejącej liczebności kobiet w wieku rozrodczym, jak również czynniki społeczno-kulturowe, w tym będące efektem drugiego przejścia demograficznego, zmiany w realizowanych modelach rodziny i dzietności, które znajdują odzwierciedlenie w preferencjach i postawach wobec prokreacji.
For three decades, the fertility rate in Poland has been below the level of simple replacement of generations, and long-term demographic forecasts do not indicate any immediate improvement in this respect. The measures taken in recent years as part of a pro-family policy have proved to be ineffective. This also applies to the “Family 500+” programme introduced in 2016. After an initial increase noted between 2016 and 2017, the fertility rate dropped again. The article attempts to answer the question as to why the programme, defined as a pronatalistic one, does not yield the expected results despite the announcements of its creators. The analysis of the causes of this phenomenon takes into account both demographic conditions, resulting from the decreasing number of women of reproductive age, and socio-cultural factors, including those resulting from the second demographic transition, changes in family and fertility models, which are reflected in preferences and attitudes towards procreation.

Opis:
This study is an assessment of the impact of the nuptiality component on the change in the fertility process, which is part of the demographic transition in Rwanda. It focusses on indicators such as age of first marriage, rates of divorce, separation, marriage dissolution, widowhood, polygamy, and number of unmarried people, for their impact on the change in total fertility rate (TFR) in Rwanda. Further, the study examines nuptiality level and behaviour in Rwanda. It is based on the investigation and interpretation of data from various reports of the National Institute Statistics of Rwanda (NISR) and the World Bank (WB), as well as data from experiments conducted by the researcher. The study concluded that, according to most of the reports, these indicators of nuptiality did contribute to the change of TFR during the demographic transition in Rwanda. Further, it recommended that the public statistical institution (NISR) should conduct a study on homosexuality and its impact on TFR in Rwanda. This study consists of four sections: section 1 - introduction; section 2 - literature review; section 3 - data and methods; section 4 - analytical methods, results and conclusion.

Opis:
In the progeny of a hybrid obtained after crossing local Polish and local Bulgarian white clover genotypes one octoploid (2n=64) plant was selected. In view of difficulties to obtain seeds, the octoploid plant was vegetatively propagated. The progeny of the octoploid obtained as a result of self- and cross-pollination of cloned plants was examined and compared to related tetraploids with respect to morphological characters, fertility and embryo sac structure. Vegetative and generative organs of the octoploid were slightly larger than those of tetraploids. The number of flowers per head was larger in the octoploid than in tetraploid plants. The spontaneous octoploid appeared to have a low fertility after both cross- and self- pollination. It was most probably caused by low pollen viability, by decline of megasporocyte and megagametocyte in the process of ontogenesis and by a smaller ovule number per ovary. Seeds of octoploids were partially underdeveloped and only 23.85% of them gave rise to seedlings.

Opis:
Ciąża szyjkowa jest najrzadszą formą ciąży pozamacicznej. Wskutek oddziaływania wydzielanych przez trofoblast enzymów proteolitycznych na ścianę dużych naczyń krwionośnych, ciąża szyjkowa prowadzi do masywnych krwotoków zagrażających życiu. Metody leczenia zachowującego płodność obejmują ogólnoustrojowe lub lokalne podawanie leków cytotoksycznych. Według piśmiennictwa leczenie z ogólnoustrojowym zastosowaniem leków cytotoksycznych jest nieskuteczne, gdy stężenie HCG w surowicy krwi jest wyższe niż 10000IU/ml. W prezentowanym opisie przedstawiono przypadek skutecznego leczenia zachowawczego z zachowaniem płodności u kobiety z ciążą szyjkową, u której stężenie HCG w surowicy krwi wynosiło 74000IU/ml. Efekt kliniczny uzyskano stosując dożylnie metotrexat oraz prostaglandyny.
Cervical pregnancy is the rarest form of ectopic pregnancy. Resulting from the interaction of the trophoblast-released proteolytic enzymes on the wall of large blood vessels cervical pregnancy may lead to massive, life-threatening haemorrhages. Methods of treatment preserving fertility encompass systemic or local administration of cytotoxic drugs. According to the literature, treatment with systemic application of cytotoxic drugs is ineffective when level of serum hCG is higher than 10000IU/ml. This report presents a case of effective conservative treatment preserving fertility in a woman with cervical pregnancy who had level of serum hCG 74000IU/ml. Clinical effectiveness was achieved by intravenous methotrexate and prostaglandin injections.

In this way, it influences the growth of private consumption and contributes to the stimulation of the economic growth. However, the main goal of the program is to improve the fertility rate and social conditions of large families. In particular, the elimination of the phenomenon of extreme poverty. The article will attempt to answer the question to what extent the main objectives of the program have so far been implemented. In addition, possible changes to the design of the program will be considered so that it can meet its objectives more effectively.

These processes create negative consequences for all areas of social life. Therefore, there are necessary appropriate actions of family policy. The main aim of this article is to show the statistical data connected with these processes which be the basis for discussion about family policy and its actions. The first group of actions is connected with support for polish families and parents which lead to decisions to have a child. While the second group is focused on the elderly and their needs. Only multifaceted government actions can be effective in the current demographic situation in Poland.

Male fertility restoration of F1 crosses between male sterile lines (P lines) and restorers (R) was studied in 2000. Pollen fertility of 50 F1 crosses derived by crossing 10 P lines to 5 restorers was estimated. The degree of male sterility/fertility was assessed by visual anther score of single plants on a 1-9 scale, restorer indices and visual pollen shedding scores of plots on a 1-9 scale. @Abstract = Coefficients of correlation between the above fertility traits were calculated. The analysis of variance showed that the degree of male fertility of F1 crosses strongly depends on a restorer genotype, a P line genotype as well as on the P ´ R interaction. The restorer and P line genotypes were a major source of variation.A considerable range of pollen fertility was evident in the single crosses. The mean restorer index of F1 crosses ranged from 3,4 to 98,7%. The P lines under study were divided into three groups on the basis of mean restorer indices of their crosses with five restorers: easy, medium and difficult to restore. All the restorers tested, provide a sufficient restoration of male fertility of the F1 crosses with majority of the P lines. The new restorer, 330 R appeared to be more effective in restoration of pollen fertility than the other currently used lines

Demographic changes are one of most important elements that have influence on functioning states on many levels. Changes in numbers and structure of population have specific effects – social and economic, but most importantly at security of state. In Poland situation is special, because over the 20 years can be observed very unfavorable changes in population, which in long term perspective can lead to reducing the defense potential. The purpose of the article is to analyze demographic changes in Poland between 2001-2020 years in terms of their importance for national security. Used time period was selected due to changes that began in the 21st century. In the research process the following methods and techniques were used: analysis and criticism of literature and other sources, statistical analysis. Layout of the article shows the course of the research process. At the beginning demography and national security definitions aspects were analyzed. Next, observed demographic changes between 2001 and 2020 were described. Later, impact of identified changes at national security were analyzed. The article ends with a summary and indication of the key conclusions.

Opis:
Three profile pits were sunk along a toposequence of basaltic soils in Ikom, Cross River State to determine their morphological and physicochemical properties. The profile pits were morphologically described and thirteen (13) soil samples were collected from different horizons of the profiles for physicochemical analysis. Morphologically, the soils were deep and well drained with no concretions. The colour of the surface soils varied between dark reddish gray (5YR4/2) and dark brown (7.5YR 3/2) to dark reddish brown (5YR 3/4), while that of the subsurface varied between red (2.5YR 4/6) to reddish brown (2.5YR 4/4). The soils had sub-angular blocky structure of different grades and classes with predominantly clayey texture in the Ap horizons and very gravelly clayey texture in the Crtg horizons. The chemical analysis revealed that exchangeable Ca2+ was the most dominant cation amongst the exchangeable bases. The soils were low in total nitrogen, organic carbon, available phosphorus and very high in base saturation. The study showed that the soils are moderately fertile and as such, a lot has to be done to improve their fertility status through the application of organic and inorganic fertilizers with good management practices such as mulching with crop residue after harvest, sowing of crops at low density per hectare, conservative tillage, strip cropping, crop rotation and shifting cultivation to ensure sustainable productivity.

Opis:
Demographic factors have sometimes occupied center-stage in the discussion of the sources of economic growth. In the 18th century, Thomas Malthus made the pessimistic forecast that GDP growth per capita would fall due to a continued rapid increase in world population. There is a straightforward accounting relationship when identifying the sources of economic growth: Growth Rate of GDP = Growth Rate of Population + Growth Rate of GDP per capita, where GDP per capita is simply GDP divided by population. This article examines the interconnection between economic development and the demographic policy of Azerbaijan. The article analyzes various approaches of the impact of demographic factors on the economic development of a country. The following demographic factors have been identified and described as significant for the economic development: fertility dynamics, mortality dynamics, population size and gender and age structure.

Opis:
Education is one of the most important determinants of fertility. The vast majority of previous research on the effect of educational level on reproductive behavior concerns women, while a couple perspective on fertility, although seems natural, is often omitted. Couples’ fertility might be influenced by individual (absolute) characteristics of both partners as well as by their joint (relative) characteristics. The aim of this study is to analyse childlessness and fertility by couples’ educational profile which is a combination of both partners’ educational levels. Different levels of educational exogamy are considered. Based on the two waves of Polish Generations and Gender Survey (GGS-PL) couples who completed their reproduction as well as those who are still in their reproductive ages are analysed. Among homogamous profiles the level of education negatively influences couples fertility, which means that highly educated have the lowest number of children. However, the level of (definite) childlessness is one of the highest among those who are low educated. Family size of heterogamous unions are similar among older generations, but for younger couples hypogamy limits the number of children as compared to hypergamy. This finding suggest that young couples in which women are more educated than their partners encounter more difficulties in combing work and family than unions in which a man is more educated than a woman.

Opis:
The article provides an assessment of soil fertility indicators of agricultural lands in the northern forest-steppe of the Republic of Bashkortostan within the Iglinsky region (Russian Federation). The content of humus, mobile phosphorus, exchangeable potassium, the thickness of the humus horizon, granulometric composition, morphological properties and soil washout were studied. It was revealed that the soil-forming process occurs on rocks of different ages and genesis, such as diluvial carbonate and carbonate-free clays and heavy loams, limestone eluvium, sandstone eluvium and alluvial deposits, which determine the diversity of the soil cover. In the study area, water erosion processes are developing, influenced by anthropogenic and natural factors such as planar and linear washout on slopes with a steepness of more than 2-3° and high ploughing of agricultural land. In terms of humus content, low-humus and medium-humus soils are widespread, accounting for 45.5 and 40%, respectively. The soil map was corrected and digitised to identify the main types and subtypes of soils, indicating the varieties at a scale of 1: 25,000. Digitised maps, taking into account the current state of soil fertility, are used to develop projects for inter-farm and intra-farm land management of organisations of the agro-industrial complex, state cadastral valuation of agricultural land, determination of land tax and development of measures to improve soil fertility.

Opis:
SFMToolbox is an ArcGIS Python toolbox developed in ArcGIS Desktop (ArcMap) to perform preprocessing tasks for the automatic creation of maps of soil fertility parameters. Through SFMToolbox, users can automatically produce 12 soil fertility parameter maps as a batch at one time. It is easy to use, where users can only provide input; the output files are automatically created from the name of the sample point and saved in the defined workspace. During the execution of the tools, various processes, such as Inverse Distance Weighted (IDW) – a technique of interpolation, reclassification, adding color, merging, projection, area calculation, and legend are done automatically for all 12 parameters at the same time. The SFMToolbox was validated as part of the following case study: village – Kashipur, tehsil – Balrampur, district – Balrampur, state – Uttar Pradesh, Country – India. The results show that the user can quickly generate maps and save time, improve accuracy, and reduce human intervention and ensure uniformity among maps. This toolbox also applied to Cycle II data from the Government of India’s Soil Health Card (SHC) scheme and timely produced 12-parameters soil nutrient maps for 630 districts in a uniform format. The toolbox may be used by public and private organizations to make timely decisions on agricultural and environmental issues.
