Opis:
This article presents the results of the numerical investigation of the thermal stratification in the hot water storage tank. The exchanger consists of three tube coils that are immersed in the storage tank of hot water. Two coils—lower and upper—are designed to warm the water in the tank using the water as a heating medium. Another coil—uses the refrigerant for the waste heat transfer. The temperature stratification device is mounted in the thermal storage tank. The device’s task is to improve the thermal stratification level of heated water. The performed numerical simulations allowed us to obtain the temperature and velocity fields in the storage tank under the conditions of the work of coils filled with water. Calculations were made in the case of the use of the stratification device under the operating conditions of the 10.2478/amst-2019-0015upper and lower coils with water.

Opis:
The main aim of the analysis is to determine to what extent preference for specific musical genres is related to social position. The study was based on data from a survey conducted in 2019 on a random sample of Poles. The explained phenomena are six genres representing broad spectrum of musical tastes: classical music, jazz, rock, rap, pop, and disco polo. The results of the analysis indicate that the diversity of musical tastes does not come down to one dimension. Family socialization, educational level, and, in part, class position exert the highest impact not only on preferences of classical music but also on liking jazz, rock and disco polo. The class effect appears almost negligent in preference for pop and rap which lead us to general conclusion that cultural stratification does not cover all forms of activity having a selective effect. Musical preferences turn out to be extremely strongly connected with parent’s cultural capital and respondents’ level of education.

Opis:
The Dogons - it is one of the today better known tribes of the West Africa. Getting known their culture has been recently associate only with perfect investigations of French ethnologists concentrated around Marcel Griaule. The author, for the first time, encountered the Dogon Tribe over 30 years ago. The multiple returns (often to the very same places) have made possible to observe their culture within the space of many years. The author has got to know many representatives of this tribe, some of them fleetingly, but with some of them he has been in touch until today. Atmo Domno - an inhabitant of a village called Yougo Na can be rated among the second group. However, Atmo Domno was not an "ordinary" Dogon. By virtue of his birth, he belongs to a group of Dogons highly positioned within the social hierarchy, who decide about not only the village Yougo Na life, but also of whole tribe, as Atmo is a member of a group of so called "Impure". In the Dogon Tribe the "Impure" take care of rituals connected with death, they prepare deceased for the funeral and bury him, they make the offerings, eat sacrificed animals, build solitude huts for women, etc. The status of "Impure" is necessary to run for position of Olubaru - the leader of a secret association Awa. As opposed - the "Pure' innenomo can not do any rituals connected with death, make offerings or even hunt. But, on the other hand, the status of "Pure" in required for being a Hogona. With time, Atmo became a Binukedine (leader) of his clan, but he resigned at the moment of becoming Olubaru in the association Awa in Yougo Na, which means to have one of the highest religious statuses in Dogon Tribe. Olubaru from this village will have an unquestionable influence inter alia on: look and course of the forth- coming holiday of Sigui. Unfortunatel y, Amo had faint chance to live till this next holiday, as it will start around year 2028. Atmo Doumbo died in 2000. During my stay in Yougo Na in 2006, I was shown a several years old boy named Hamidou, in whose body lived a soul of nani Atmo, after his death, and who becomes the next "Impure".

They set up, as a one-time „selection act”, the trajectory of a career and the whole future life of young Chinese. At the same time, they are an example of the entanglement of the testing process in politics and of the enormous (and overwhelming) social pressure on young people.

The results demonstrate the absolutely nuclear role of language in that community, in all target groups. The case of Almería, very probably, shows a universal pattern of sociolinguistic behaviour. In principle, it confirms the theoretical and methodological hypothesis developed in Australia. They also highlight the relevance of interdisciplinary-based research, from which valuable descriptive results can be obtained for the disciplines involved.

Monitoring of surgical outcome is increasingly important part of governance of surgical activity. The aim of the study. POSSUM scoring system was applied prospectively to determine how it performed in predicting morbidity and mortality in patients undergoing emergency laparotomy in our hospital, a group known to be at high risk of complications and death. Material and methods. A total of 100 cases of emergency laparotomies were studied in patients admitted in general surgery department during the period of May 2008 to August 2010. The study group consisted of the following cases. Duodenal perforation (37 cases), intestinal obstruction (27 cases), gastric perforation (8 cases), ileal perforation (8 cases), appendicular perforation (7 cases), blunt trauma (4 cases) and others (9 cases). They were scored using POSSUM scoring system. Physiological scoring was done at the time of admission and operative scoring was done intraoperatively. They were followed up for the first 30 day post operative period for any complications and the outcome was noted. The observed morbidity and mortality rates were compared with the POSSUM predicted morbidity and mortality rates. Results. 15 patients died (mortality rate of 15%). The POSSUM predicted mortality was 20 deaths. O:E ratio of 0.71 was obtained. There was no statistically significant difference between the observed and predicted mortality rates (χ2=1.72, p=0.974). 71 patients experienced complications. The POSSUM predicted morbidity was 61 patients. O:E ratio of 1.19 was obtained. There was no statistically significant difference between the observed and predicted morbidity rates (χ2=1.594, p=0.991). Conclusions. POSSUM scoring is an accurate predictor of mortality and morbidity following emergency laparotomy and is a valid means of assessing adequacy of care provided to the patient. POSSUM can be used for surgical audit to assess and improve the quality of surgical care and helps in better outcome to the patient

Opis:
Konceptualną ramą badań nad ruchliwością jest teoria modernizacji. Stwierdza się w niej, że wzrost otwartości jest dominującą tendencją, która wynika z postępującej liberalizacji i rozwoju gospodarki rynkowej. Wbrew tym oczekiwaniom bariery ruchliwości okazują się na ogół stabilne. Ustalenia te dotyczyły głównie zachodnich demokracji. Nasza analiza jest kontynuacją tego podejścia w odniesieniu do Polski. Opierając się na danych z lat 1982–2016 wskazujemy, że po pierwsze, dokonuje się systematyczne obniżenie wpływu wykształcenia na pozycję zawodową, co przeciwdziała zwiększaniu się ruchliwości międzypokoleniowej. Po drugie, tendencja ta nie obniżyła jednak tzw. względnych szans ruchliwości, chociaż mogło to być bardziej związane z przekształceniami struktury zawodowej niż ze wzrostem otwartości barier społecznych. Po trzecie, za stabilnym charakterem wzorów ruchliwości przemawia utrzymywanie się nierówności edukacyjnych. Po czwarte, okazuje się, że w odróżnieniu od badań w innych krajach, w przypadku Polski, wyższe wykształcenie nie osłabia, ale raczej wzmacnia znaczenie dziedziczenia pozycji rodziców.
This paper deals with changes in the “openness” of Polish society over a 35-year period, focusing primarily on relative mobility, with some attention to changes in absolute mobility. We disentangle intergenerational occupational association into four interrelated parts: (i) relative mobility defined by the effect of social origin on destination, (ii) the relationship between social origin and education, (iii) the net effect of education on destination, and (iv) the compositional effect of education reflected in the rising share of more educated categories in the social structure. We show that changes in social fluidity were neither systematic nor easily interpretable. While our results reveal a consistently declining association between education and occupational position, unidirectional change could not be identified in the social origin-education link and in relative mobility in terms of the association between origin and destination. The origin-destination association generally increased at higher (rather than lower) educational levels.

Opis:
Among the phenomena that characterize modern society it is possible to note the appearance of complex political, occupational, and sectorial systems of status and the weakening of the ‘class’ factor in its ideological meaning. The main result of this development was the steadily increasing conflictbetween, on the one hand, the trends of economic development and the new centers of power and, on the other hand, the mobility of new groups. All the groups competed among themselves over the additions of income, accessibility to economic resources, and positions of influencein the government system as well as over the creation of autonomous frameworks. An important part in these sectorial formations is related to the positioning of education in the entire stratifiedsystem. The statement that the extension of education has not resulted in the reduction of social gaps in the professional field,especially between employees, is correct, yet conversely it did drive a process of change in the evaluation of different subjects and a change in the perception of education as a necessary state of specialization. This aspect constitutes an important factor in the processing of the stratifiedmap and in the formation of the class awareness. The education systems, which are the main organizations to inculcate education, can determine who is qualifiedand who is not qualifiedto filldifferent employment roles; they have become the main device for the achievement of social and economic status.

The article presents four perspectives on the family. In the intergenerational perspective a family is an institution of biological and cultural reproduction. Family in the perspective of the life cycle is a dynamically changing structure of “problems to solve” associated with life cycle: socialization, mating, parenting and post reproductive phase. Each phase substantially changes the structure of interests, available resources and the nature of social relationships. Family in the system of social stratification is associated with the distribution of scarce resources. The family as a system of social interaction is a complex dynamic unit which stabilizes the basic structure of the moral code (attitudes of loyalty and trust).

In this article, the Cum Di(x,z) Rule (i=3,4) for obtaining approximately optimum strata boundaries has been applied, taking into account a single-study variable along with two concomitant variables serving as the basis of the stratification variables. The relative efficiency of the proposed methods has been demonstrated theoretically and empirically by comparing them to a selection of already-existing methods in a simulation study with the use of the proportional allocation method.

Opis:
The problem of the complexity of social stratification in Sub-Saharan Africa, leading often to the title "exclusion" is not always noticed in recent literature, either ethnological or socio-political. It goes far beyond the fashionable topics of tribalism, ethnicity, or even the problem of creation of the people in the countries of this continent. That shows like "hidden meaning" of the first phenomenon that does not fit tightly to the theory of the modem state. During a recent survey in Mali among the Dogon community, in years 2008-2009, the problem of exclusion outlined very clearly. It is known as principle of conduct concerning, inter alia, to marry. Today, the "races" among whom are looking for a wife not just blacksmith, artisans groups belonging to scheduled castes (basket-maker, vesicle etc.) but also the descendants of former slaves. Violation of the ban results in finding a group of "hybrids" - hassobe. The common history and community of residence for hundreds of years, as it turns out, does not even today to a homogeneous ethnic group.

Opis:
Most stratification research concerns solely the economically active population and omits inactive seniors. Retirees are often treated as a separate and rather homogeneous social category. However, this approach is only partially valid. Retirees can still be differentiated in regard to their objective and subjective well-being, which is linked to their former occupations. Using large EU-SILC datasets for Central European countries, this article focuses on the effect of pre-retirement socio-occupational category on the well-being of retirees. The category is found to be an important explanatory variable after controlling for age, sex, marital status, and other characteristics. However, there are substantial differences among countries. While in Czechia, retirees are most homogeneous in regard to their objective and subjective well-being across socio-occupational categories, the differences are considerably larger in Hungary and Poland, and on a similar level as in our benchmark country, Austria.

Opis:
The basic aim of the task is to compile a temperature stratification system in an accumulation tank. The range of the thesis concerns the shape and dimensions of a stratification system for an accumulation tank. Thermal stratification is a process that comprises the maintaining of temperature stratification at different levels of an accumulation tank which reduce to a minimum the process of temperature equalization. It results from the fact that the thermal stratification in a tank significantly increases the installation efficiency and improves the process of energy storing. It is connected with a thermodynamic element quality, that is the higher the temperature, the higher the energy, and, thus, the thermosdynamic element quality. In this phenomenon, thanks to the same amount of accumulated thermal energy and average temperature, as in a fully mixed tank, the user has a higher temperature in the upper part of the tank at his disposal. It has significant importance in the case when there is a low-temperature heating medium that transfers heat to the accumulation tank. Such a situation occurs when heat is absorbed from synthetic freons used in cooling and air-conditioning systems.

Opis:
Several event layers have been identified in lacustrine deposits in the AErI Basin of Anatolia (E Türkiye). Sedimentological and palaeontological data newly indicate a storm-induced origin for some of them. The sedimentary structures in three sections, a few tens of metres apart from each other laterally, such as hummocky cross-stratification, wave-generated cross-bedding, parallel bedding, erosional surfaces, and graded bedding, which are considered characteristic of tempestites, are clearly present. Additionally, fining-upwards units and biogenic escape structures located at different levels of these sections indicate a similar origin. The vertical variations in layer thickness, grain size, and sedimentary structures in these sedimentary sections indicate fluctuating hydrodynamic conditions during deposition, while lateral decrease in the size and wavelength of the structures reflects deepening. This interpretation of storm-induced deposition is compatible with regional palaeoclimatological and palaeogeographical data, and is supported by evidence of Quaternary storm-induced sedimentation in adjacent lacustrine basins in the region.

Opis:
In his article, the author outlines the values preferred by teachers and those aspiring to the profession. The presented data point to a very broad convergence between what teachers and students indicated with regard to their attitude towards values. Although one can observe certain, rather subtle, differences (related to, among others, the socio-demographic characteristics of those surveyed), they are of secondary importance and do not cause the axiological bases for the functioning of both groups to differ. What is significant is also the placement of such values as safety, responsibility and children. These values have a static character, connected with necessity and, at the same time, with the need to maintain one’s property. They proved to be slightly more appreciated by teachers than by students. The research shows one essential yet weak correlation: two values, wisdom and honesty, find a slightly wider acknowledgement among teachers than among their future colleagues. The same can be said of the case when the same values are chosen as primary. In this context, referring everything that takes place in the social space to distant, better times seems to be justified. No matter how it was in the real historical dimension, it appears justified to assert that it is undoubtedly better to live in an environment where the majority of those representing a given professional group (especially one as important for the social structure as teachers) recognise the importance of wisdom and honesty.

Opis:
This article outlines developments in empirical research on social stratification in the four countries constituting currently the Visegrád Group (V4). Sociology has been developing, if unevenly, as a discipline in these countries since the 19th or early 20th century. Empirical research on social stratification, based on data collected in large surveys, started here by the mid-1960s, first in Poland, then in Hungary, and later in the former Czechoslovakia. In spite of the ideological pressure of the communist regimes in all of these countries, the conditions for sociological studies were much better in Poland and Hungary than in Czechoslovakia, where such research was frozen for a long time after the communist putsch of 1948 and again after the Soviet occupation in 1968. After 1990, this kind of research enjoyed an energetic new start in all the post-communist countries, as they opened fully to the West and integrated into international networks. In addition, comparative research within the V4 region started with the challenging project “Social Stratification in Eastern Europe after 1989.” Many national surveys were conducted and East-West cooperation intensified. Currently, most empirical research on social stratification occurs on a national or bilateral basis, or is developed within larger European projects.

Opis:
The problem of estimating a proportion of objects with particular attribute in a finite population is considered. This paper shows an example of the application of estimation fraction using new proposed sample allocation in a population divided into two strata. Variance of estimator of the proportion which uses proposed sample allocation is compared to variance of the standard one. In the paper an application of sample allocation described in Sieradzki & Zieliński [2017] is presented."

While Industrial Revolution helped England to become a great power in the world, capitalism created a huge gap between the middle classes and working classes. Observing the condition of the society, Marx and Engels created their famous claim of class struggle in The Communist Manifesto. They emphasized the gap between two classes and how to revolt against the capitalist system by the working class. This paper ventures to study the class issue in the Victorian society from the perspective of the Marxist literary theory. It analyses how the capitalist system makes working class people’s life miserable while it enriches the lives of middle class people. In this respect, Elizabeth Gaskell’s novel Mary Barton will be studied together with the links between the novel and The Communist Manifesto.

Opis:
This paper presents findings on the changes in social stratification in Poland, with particular attention given to mobility and marital choices. The author begins with an overview of the concept of social mobility, i.e. shifting of individuals or other categories in social space, including its definitions, indicators, patterns and mechanisms. Next, based on a set of empirical data, the author discusses the patterns of mobility and martial choices in the aftermath of 1989 transition in Poland. Special attention is given to the analysis of the openness of Polish society, opportunities for intergenerational mobility and its consequences.

Opis:
The article discusses the issue regarding the reconstruction of social structure of the early Scythian populations from the forest-steppe area of the Dnieper river, in the period between the second half of 6th–4th/3rd century BC, on the basis of funeral materials. As a result of the analysis of the most important elements of burial rites implemented by the discussed population groups, and based on records of ancient authors (The Histories by Herodotus), it has been established that the most valuable sources are the size and complexity of the funerary structure and covering embankment as well as quantitative and qualitative diversity of included inventory. The classification developed on the basis of 198 burials, by means of statistical inference methods, has led to the separation of several classes of graves that can be combined with different social strata. These layers included nomadic higher spheres (leaders of local communities, leaders of “military teams” and tribal aristocracy) and elites of local settled tribes, average members of the population divided into its wealthy representatives and the so-called “simple Scythians” and lower layers of (“the poor”) and people with limited rights (domestic slaves?).
