Opis:
This theoretical article presents a case for a new approach to the teaching of word recognition in English as a foreign language to young learners in Polish early years education, arguing that there is a need for greater attention to explicit instruction in alphabetic principles, selected phonics and decoding skills. Research in first language (L1) English and foreign language (L2) development of word recognition skills is outlined. Differences between the orthographies of Polish and English are highlighted. Approaches used in L1 early reading instruction are contrasted with those commonly applied in L2 settings. The need for more explicit instruction is rationalized on the basis of a brief description of impressions from 20 hours of classroom observation. The second part of the paper presents some principles for the design of materials to introduce alphabetic principles of English and elements of phonics to support word recognition, with examples. The ability to recognize words rapidly and with ease is a key skill, which, unless mastered early, could potentially have a negative impact on the whole of a child’s language education.

Opis:
The article examines the possibilities of fostering young L2 learner print awareness via teaching for conversing about and reflecting on writing. In order to achieve this goal the present author conducted the qualitative research on a group of 2nd-graders engaged in the performance of a series of open-ended L2 written tasks accompanied by L1 cues. The analysis of collected data shows that drawing children’s conscious attention to writing might encourage the constructive transferability of linguistic skills from L1 to L2, thus being conducive to the development of logical thinking necessary for the enhancement of their print awareness.

Opis:
This scoping review explores the causal relationship between morphological instruction and reading development in young L2 learners by synthesizing 12 primary studies published between 2004 and 2019 (N = 1,535). These studies focused on reading English as the target language and involved participants between kindergarten and Grade 12 from four countries (China, Egypt, Singapore, and the USA). Findings suggested that (a) morphological instruction led to consistent and positive gains in L2 children’s morphological awareness and vocabulary knowledge, and the effect sizes (Cohen’s ds) ranged from small to large; and (b) the relationship between morphological instruction and other outcomes such as phonological awareness, word reading accuracy, word reading fluency, spelling, and reading comprehension was inconclusive. Notably, transfer effects of L2 English morphological instruction on novel word learning in English or on reading development in an additional language were only examined and observed in four primary studies. Discussion was provided regarding future instructional and research design.

The aims of the study were to identify the fungi associated with the decay of thin roots (1-5 mm) of 1, 3 and 15-year-old Fraxinus excelsior plants and to estimate the pathogenicity of certain fungi. In total, 400 fungal isolations were performed from which 334 cultures were obtained. Altogether, 26 species of fungi were identified. The following species were most frequently obtained, independently of plant age and origin: Alternaria alternata, Chaetomium globosum, Cryptosporiopsis sp., Fusarium oxysporum, F. solani and Cylindrocarpon destructans. The last three of these were then used in an inoculation test. F. oxysporum caused the death of over 80% of 2-month-old seedlings grown in boxes containing perlite and kept in a growth chamber.

Opis:
Phytochemicals, proximate, minerals and anti-nutrient compositions of young cocoyam (Colocasia esculenta) leaves were determined using standard methods. Qualitative and quantitative analyses for phytochemicals confirmed the presence of bioactive constituents such as alkaloids, flavonoids and saponins in appreciable amounts, while terpenes, cardiac glycocides and tannins were only present in trace concentrations. Mineral analysis revealed that K recorded the highest content - with 214.00 ± 2.11 mg/100g, followed by Ca - 157.10 ± 1.47 mg/100g, Mg - 63.00 ± 0.58 mg/100g, P - 32.00 ± 0.61 mg/100g, while Fe had the lowest value - 0.10 ± 0.14 mg/100g. Proximate composition analysis of C. esculenta leaves indicated that CHO, protein and crude fibre were present in high quantities (35.22, 17.10 and 16.41 % respectively), while fat was at the lowest content (8.82%). Anti-nutritional factor analysis of young leaves of C. esculenta indicated that phytates was present in huge quantity - 11.03 ± 0.12mg/g, followed by oxalates - 7.62 ± 0.14 mg/g, while tannins recorded the lowest anti-nutritional contents - 0.12 ± 0.06 mg/g. This study has also revealed that the young leaves of C. esculenta contain appreciable levels of bioactive components (phytochemicals such as as alkaloids, flavonoids and saponins; minerals K, Ca, Mg, P and Fe) and appreciable amounts of CHO, protein and crude fibre. The results of anti-nutrients analysis showed high contents of phytate and oxalate. The last is probably responsible for the itching effect and also interferes with the utilization of essential nutrients. Thus, young leaves of C. esculenta provide appreciable quantities of nutrients and thus can rival other conventional vegetables normally consumed in Nigeria.

Opis:
The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.

Opis:
In the Kolbuszowa Plateau forest areas, aggregations of brambles were observed most often in young forest plantations and forest clear cuts. In the 20 plantations that we examined, 11 bramble species were found. The most common bramble species in young forest plantations were Rubus plicatus, R. nessensis, R. hirtus, R. idaeus and more rarely R. gracilis, R. ambrosius and R. apricus. The largest bramble aggregations occurred in plantations located in mixed pine-oak forests, subcontinental lime-oakhornbeam forests and drained black alder forests. In young forest plantations the Rubus species were accompanied by species characteristic for the Vaccinio-Piceetea, Querco-Fagetea, Epilobietea angustifolii, Molinio-Arrhenatheretea and Nardo-Callunetea associations. There are three groups of bramble species which occur in young forest plantations: I – species with thin, prostrate and rooting stems (R. hirtus, R. apricus, R. pedemontanus), the negative impact of which on tree seedlings could have been very significant if the bramble specimens or diaspores had been present at the moment of tree planting; II – species with strong, poorly branched and arched stems (R. plicatus, R. gracilis, R. ambrosius, R. glivicensis), which negative influence on tree seedlings depends on the capability of the species to produce a big, dense bush in a short period of time thereby increasing shade; III – species with erect and relatively sparsely growing stems (R. idaeus), which are not a threat for the young forest plantations. Species with intermediate features (e.g. R. nessensis) may have a negative impact on young plantations generating a large, dense aggregation, however in most cases their populations only grow sparsely and do not hinder the growth of tree seedlings.

In the paper the density, height, diameter, slenderness and vitality of the 17 year−old pine young−growth stands depending on the basal area of the shelterwood (four thinning variants: G1−G4). The studies were carried out in eleven 70−90 year−old pine stands heavily damaged in the 80s of the past century by the nun moth (Lymantria monacha L.). With the development of the overstorey the growth, the vitality and the stability of young stands declined. In addition, a decrease in the survival of the young−growth stands under the dense canopy (variant G4) was recorded. A long−term maintenance of young stands under the shelter of the canopy in the areas of low annual precipitation (below 600 mm) requires the reduction of the dbh basal area to the level of at least 15 m3/ha before attaining the age of 15 years.

Opis:
Mineral nutrition of apricot is very specific and depends on different factors such as soil fertility, soil pH, weather conditions, cultivars, rootstocks, fertilizers, age of trees etc. For these reasons, during 2008 and 2009 we evaluate nutrient status of five apricot cultivars (Vera, Aleksandar, Biljana, Harcot, Roxana) at 120 days after full bloom (DAFB) grown on acidic soil in the region of ýaþak (Western Serbia). The results showed no statistically significant variations in the N, K and Ca content of apricot leaves among cultivars, as opposed to significant differences in the content of P, Mg, Fe, Mn, Cu, Zn and B. The ȈDOP index revealed that the average content of all macro- and micronutrients was below the optimum, except that of P in both years and that of Mn and Cu in the first year of the study. The insufficient nutrient supply of the test apricot cultivars requires adjustment of fertiliser types and application rates to this soil type according to foliar analysis.
Odżywianie mineralne moreli jest bardzo specyficzne i zależy od różnych czynników, takich jak: żyzność gleby, pH gleby, warunki pogodowe, odmiany, kłącza, nawozy, wiek drzew, itp. Z tych powodów, w latach 2008 i 2009 oceniamy poziom odżywienia pięciu odmian moreli (Vera, Aleksandar, Biljana, Harcot, Roxana) w 120 dni po pełni kwitnienia (DAFB), hodowanych na glebie kwaśnej w regionie ýaþak (Serbia Zachodnia). Wyniki nie wykazywały statystycznie istotnych odchyleń w zawartości N, K i Ca w liściach moreli różnych odmian, w przeciwieństwie do znaczących różnic w zawartości P, Mg, Fe, Mn, Cu, Zn i B. Wskaźnik ȈDOP wykazał, że średnia zawartość wszystkich makro- i mikroskładników odżywczych była poniżej optymalnej, oprócz P w obu latach oraz Mn i Cu w pierwszym roku badań. Niedostateczne zaopatrzenie w składniki odżywcze testowych odmian moreli wymaga dostosowania typów nawozów i zastosowanych dawek do typu gleby, zgodnie z analizą liści.

Opis:
Biostimulants offer a novel approach for the regulation of crucial physiological processes in plants. Recently, it has been observed that the application of biostimulants on both seeds and plants may ameliorate to some extent the negative effects of abiotic stresses such as drought, heat, salinity, and others. In the climate conditions of Bulgaria, the early developmental stages of warm climate crops, like maize, often occur under suboptimal temperatures. Although the mitigation of abiotic stress is perhaps the most frequently cited benefit of biostimulant formulations, little is known about their influence on chilling-stressed plants. The aim of our study was to evaluate the effects of a biostimulant from the group of protein hydrolysates on both the growth and the photosynthetic performance of chilling-exposed young maize plants grown in controlled environment. Here, we report that application of a protein hydrolysate increased the performance of chilled maize plants, as demonstrated by leaf gas exchange, photosynthetic pigment content, and chlorophyll fluorescence, but did not affect their growth. Nevertheless, based on the better preserved photosynthetic performance of the biostimulant-treated maize plants exposed to chilling, we assume that under subsequent favorable conditions their growth would recover more quickly as compared to the untreated ones.
Zastosowanie biostymulantów jest nowatorskim sposobem regulacji procesów fizjologicznych w roślinach. W ostatnich latach dowiedziono również, że ich aplikacja, zarówno na nasiona jak i części wegetatywne może w pewnym zakresie niwelować negatywne skutki stresów abiotycznych, między innymi suszy, zasolenia czy zbyt wysokiej temperatury. W warunkach klimatycznych Bułgarii wczesne fazy rozwoju roślin uprawnych pochodzących z cieplejszych stref klimatycznych, na przykład kukurydzy, odbywają się w okresach panowania temperatur suboptymalnych. Mimo, że łagodzenie negatywnych skutków stresu jest jednym z najczęściej podawanych korzystnych efektów działania biostymulantów, wiedza na temat ich wpływu na rośliny poddane stresowi chłodu jest wciąż niewystarczająca. Celem badań była ocena działania biostymulantów z grupy hydroli- zatów białkowych na wzrost i przebieg procesu fotosyntezy kukurydzy uprawianej w warunkach obniżonej temperatury. Aplikacja hydrolizatów białkowych miała pozytywny wpływ na wymianę gazową, zawartość barwników fotosyntetycznych i sprawność aparatu fotosyntetycznego mierzoną parametrami fluorescencji chlorofilu a, ale nie wpłynęła na wzrost roślin. Na podstawie uzyska -nych wyników można przypuszczać, że ze względu na sprawniejszy przebieg procesu fotosyntezy, rośliny kukurydzy poddane działaniu zbyt niskiej temperatury we wczesnych etapach rozwoju i potraktowane biostymulantami będą rosły lepiej po ustąpieniu suboptymalnych temperatur w porównaniu z roślinami nie poddanymi działaniu biostymulantów.

Opis:
Root−feeding insects are an increasingly studied group of herbivores, whose impact on plant productivity and are some of the most damaging forest pests in Europe. Due to the mass feeding on the roots of seedlings and older trees in young plantation and stands, Melolonthinae larvae are classified as pests, which are the most dangerous on the land dedicated to afforestation. The research was located in the Wyszków Forest District (52°43'15' N; 21°39'03' E) on the mixed coniferous and mixed deciduous forest habitats. This study evaluated sawdust traps as the method for assessing abundance of Melolonthinae larvae in Scots pine plantations established artificially from open nursery, container production, and from natural regeneration. In spring 2015 i) ‘small sawdust pits’ in rows between seedlings, and ii) pits without soil in adjacent inter−rows as control were prepared. In spring and autumn 2016, and in spring 2017 sawdust and soil from both variants of pits were sieved and Melolonthinae larvae were counted and compared. The obtained results were analyzed in two ways. The first analysis compared the occurrence of grubs in small pits with or without sawdust, while the other one analysed influence of the time of making small pits, independently for the variant with or without sawdust. The final stage was to compare the number of Melolonthinae larvae in small pits between the origin of the seedlings. We found a greater number of grubs in spring assessment than in autumn. Both kinds of small pits showed higher number of Melolonthinae larvae when compared to traditional method of ‘great pits’. The number of Melolonthinae larvae was significantly higher on the plots with container seedlings than the others. The conceptual assumptions of this alternative and environmentally safe method of ‘sawdust traps’ seems to be optimistic.

Opis:
In this qualitative study the author focuses on age effects on young learners’ L2 development by comparing the L2 learning processes of six young learners in an instructed setting: three who had started learning English as L2 at age 6/7 and three who had started at age 9/10. Both earlier and later young beginners were followed for three years (during their second, third and fourth year of learning English). The participants’ L2 development was measured through their oral output elicited by a two-part speaking task administered each year. Results of the analyses are interpreted taking into account each learners’ individual characteristics (learning ability, attitudes and motivation, self-concept) and the characteristics of the context in which they were learning their L2 (attitudes of school staff and parents to early L2 learning, home support, in-class and out-of-class exposure to L2, socio-economic status). The findings show that earlier and later young beginners follow different trajectories in their L2 learning, which reflects different interactions which age enters into with the other variables.

Opis:
The aim of this work was to evaluate the occurrence and harmfulness of Brachyderes incanus to young Scots pine (Pinus sylvestris L.) plantations on forest areas burned during the forest fire in 1992. The development of B. incanus outbreak had place 4 to 5 years after fire and was connected with the diminishing of macronutrients content in soil. The population of B. incanus is characterised by fast increasing or decreasing the number of individuals. During two years (two generations), the number of beetles increased from 1−2 individuals/tree (at one observation) to 50−80 individuals/tree. Also during two years, the number of beetles diminished to very low level (lower than one individual/tree at one observation). The outbreak of B. incanus in the mentioned above forest areas had place in 1999−2001.

Opis:
Teleosauridae was a group of largely marine Mesozoic crocodylomorphs, typically considered as akin to "marine gavi-als" due to their elongate, tubular, polydont rostra that are indicative of a piscivorous diet. Here we show that these extinct crocodylomorphs were more anatomically, and perhaps ecologically, varied than previously thought. We report the first evidence of denticles in a teleosaurid tooth, revealed by scanning electron microscopic (SEM) analysis of a tooth from the holotype of "Steneosaurus" obtusidens. These denticles are cryptic, because they are microscopic, not contiguous along the carinae (instead forming short series), and are detectable only using SEM. This incipient denticle morphology is similar to that recently discovered in a closely related group of marine crocodylomorphs, the Metriorhynchidae. In particular, the denticulation morphology of "Steneosaurus" is similar to that of the geosaurin metriorhynchid Torvo-neustes, indicating that these two taxa may have employed similar feeding styles and that "S."obtusidens may have been a nearshore ecological analogue to the more offshore, fast-swimming geosaurins. Previous authors have considered "S." obtusidens andMachimosaurus to be durophagous, but the discovery of denticulated teeth indicates that they had a more varied diet and feeding style, and included flesh slicing as part of their feeding toolkit. It is currently unknown how extensive denticulate carinae may be in Teleosauridae, and we hypothesise that cryptic denticles may also be present in other marine crocodylomorphs once they are subjected to SEM study.

Opis:
Motivation has been widely considered one of the most influential variables in the field of second language learning. Motivation may vary throughout the years, even within the duration of a single language class, and this might occur due to different factors, such as the choice of tasks or the activity type (i.e., collaborative or individual). These two factors have not been investigated in depth with young learners in foreign language settings, and from a task-based perspective. Thus, this paper addresses this gap, and explores the potential changes in motivation of 64 Spanish young learners of English as a foreign language who worked on a number of dictogloss tasks in pairs and individually over the span of a school year. Data was collected several times by means of different tools that measured students’ general and more specific task motivation, as well as their attitudes towards individual/pair work. The findings revealed that, overall, these children’s motivation was high and consolidated with time, while their level of anxiety decreased. Their attitudes towards the dictogloss were positive from the beginning to the end of the school year, and more so when they carried out the task in pairs. These findings support the benefits of collaborative work, and the dictogloss, as an appropriate task that engages children in their learning of a foreign language.

Opis:
The aim of this paper is to offer a comprehensive review of Polish research on translations of children’s and young adult literature. In the first part, I outline which disciplines are represented by Polish researchers who specialise in this subdiscipline, and then I present in chronological order the development of research from the 1960s, through the fertile period of the turn of the millennium, to the most recent years. Furthermore, I outline the general trends and orientations visible in research on this type of translation, placing particular attention on Polish researchers’ references to general research in Translation Studies.
L’obiettivo del presente articolo è quello di offrire un’ampia rassegna degli studi polacchi sulle traduzioni di letteratura per l’infanzia e l’adolescenza. Nella prima parte l’autrice specifica quali sono le discipline della scienza rappresentate dagli studiosi che si occupano di tale subdisciplina, per poi passare in rassegna cronologica lo sviluppo delle ricerche, dalla fase iniziale negli anni Sessanta fino ai tempi più recenti. Vengono individuate inoltre tendenze generali e ambiti di ricerca che si possono notare negli studi su tale tipologia di traduzioni, con un’attenzione particolare nei confronti dei richiami, da parte degli studiosi polacchi, alle ricerche inerenti alla scienza della traduzione.

Opis:
The paper outlines the publishing history of Henryk Sienkiewicz’s Quo Vadis in Italian editions for children and young adults in the 20th century. The research conducted so far has shown that Sienkiewicz’s novel was part of Italian publications for a young readership as early as at the beginning of the 20th century, and that the book was frequently republished and reedited by numerous publishing houses over the following decades. The paper aims to present the strategies applied by Italian publishers as they recast Sienkiewicz’s work into versions specifically targeting young readers. Sienkiewicz’s Roman narrative proved a source of easy revenue for many publishing houses. Discreditable translatory practices were, at least at the beginning of the 20th century, mainly the domain of Milanese publishers whose efforts also focused on reworkings of Quo Vadis for children and young adults after the Second World War. The paper discusses examples that vividly illustrate the commercialisation of literature and publishers’ responses to the changes of the Italian publishing market in the second half of the 20th century. The findings of a study that used quantitative methods to analyse the corpus of 18 Italian editions of Quo Vadis are presented as well.
L’articolo abbozza la storia delle edizioni italiane per ragazzi e adolescenti di Quo vadis di Henryk Sienkiewicz nel XX secolo. Sulla base delle ricerche finora svolte, è stato accertato che l’opera di Sienkiewicz comparve nell’offerta editoriale italiana rivolta ai giovani lettori già dall’inizio del Novecento, e poi per molti decenni fu volentieri riproposta da numerose case editrici. L’obiettivo dell’articolo è quello di indicare le strategie degli editori italiani che, pensando ai giovani lettori, portarono alla realizzazione di nuove versioni dell’opera di Sienkiewicz. La trama romana del romanzo di Sienkiewicz si rivelò una fonte di facile guadagno per molte case editrici e in ambito di pratiche traduttive ingloriose si distinsero, almeno all’inizio del Novecento, gli editori milanesi, offrendo, soprattutto dopo la Seconda guerra mondiale, anche rifacimenti e riadattamenti di Quo vadis per il giovane pubblico. Gli esempi riportati nel testo illustrano anche il processo di commercializzazione della letteratura e le risposte degli editori all’evoluzione del mercato editoriale italiano nella seconda metà del XX secolo. L’articolo presenta anche i risultati della ricerca sul corpus di 18 edizioni italiane di Quo vadis con l’applicazione dei metodi quantitativi selezionati.

Opis:
Patterns of nutrinal behaviour that are shaped in childhood and during adolescence are mostly continued later on in adult life. The risk of developing many chronic diseases is to a large degree dependent on these patterns. The aim of this study was to assess the relationship between dietary habits and body image perception among Polish adolescents and young adults. The study group covered 14,511 adolescents/young adults: 10,081 children attending high schools and secondary schools and 4,428 university students. More than 87% of school children and students admitted that they snacked in between meals everyday, and 1/3 mentioned that they ate meals at night. As many as 41.40% of schoolchildren and 46.70% of students experienced the feeling of overeating at least several times a week. Analysis of the respondents BMI showed that students were considerably more obese and overweight compared to schoolchildren. Fear of gaining weight was mentioned by 9.90% of respondents including 6.90% of those with normal body structure, 1.40% with underweight or overweight and 0.40% of those obese. As many as 54% of the total respondents described their body structure as being normal, 23.7% as slim, 13.9% reported being overweight, 6% thin whilst 1.7% considered themselves obese. A comprehensive analysis of the study data, including attempts at dieting or gaining weight, indicated that approximately ¾ of obese respondents had undertaken attempts in the past to reduce their body weight. The importance of physical activity and healthy eating habits should be given due attention not only to prevent obesity but also other eating disorders.
