Opis:
The subject of the article covers issues related to the presence of neoliberal educational messages in school practice. The study contains an analysis of the teacher’s narrative, the purpose of which was to identify and describe elements that fit into neoliberal assumptions of education. The reconstruction of everyday school life (micro level) enabled the manifestations of instrumentalisation of education, rivalry and competitive aspects in the teacher’s work and the practice of forming homo oeconomicus at school. Commodification of an individual in free market conditions is reflected in a profit-maximizing school, i.e., achieving high results in external examinations owing to an educational process organized effectively, and minimizing costs by, for example, selecting students and by eliminating the “maladjusted” from schools. In the text, I outline a portrait of a teacher functioning professionally, who builds his profession on the foundation of neoliberal assumptions about education. I analyze the teacher’s understanding of school education, which is present in the teacher’s narratives, as a space for a specific market game and competition, defining the effectiveness of school work by high level of students’ examination results and the original concept of working with a supervised class reduced to the implementation of a business project.

Opis:
In this study seasonal and inter-annual patterns as well as trend in the total precipitable water vapour (TPW) over Malaysia, based on a 30-year data from MERRA-2, have been evaluated using least square regression method. Indicator TPW revealed a pair of minima in February/August and maxima in May/November with highest and lowest long-term means found in East Malaysia. Long-term seasonal variability of TPW exhibited latitudinal dependency in both the NEM and SWM seasons. Indicator TPW showed respective southeast-northwest and southwest-northeast spatial distribution in West and East Malaysia, with the highest statistically significant positive trend found in the former.

Opis:
Considered the most dangerous type of thunderstorm, supercell thunderstorms appear in strictly defined meteorological conditions in the troposphere. Predicting their location is particularly problematic in an environment of strong vertical wind shear and low instability. An example of such a situation is the supercell that contributed to the development of the tornado on July 10, 2020 at 18:10 CEST in Ustronie Morskie. On that day, two dangerous supercells were also created, which, at the peak of activity, passed over Lubusz and Masovian Provinces. The tornado in Ustronie Morskie was formed on the wavy front, while the supercell developing in Lubusz and Mazovia Land was observed on the cold front. Large hail and damaging wind gusts associated with the downburst in the west of the country took place in higher atmospheric instability than the other cases. The MLCAPE was over 200 J kg–1 higher than that for peak activity of the other storms discussed in the paper. This could have been crucial for the formation of the largest hail recorded on July 10, 2020 in Poland. The highest values of wind shear and storm relative helicity occurred on the coast which could have influenced the formation of a tornado despite the low values of atmospheric instability. The hook echo radar signature in Mazovia Land developed with a similar MLCAPE as the tornado on the coast (nearly 500 J kg–1). On the other hand, the MUCAPE and SBCAPE was much higher there (approx. 500 J kg–1 more), and so was the LCL level. This proves a higher humidity deficit in the lower troposphere in the place where the hook echo passes. With regard to the ESTOFEX and Skywarn Polska convection outlook, the tornado was the most difficult phenomenon to predict. Hail and damaging wind gusts not related to rotation coincided to a greater extent with the convective outlook.

Opis:
Variability of air temperature inversions over Cracow in relation to the atmospheric circulationTemperature inversion is a phenomenon in which air temperature increases with altitude. The studies on air temperature inversions in Cracow were based on various data and methods e.g. data from standard and automatic meteorological stations, radiosonde observations, lidar and sodar measurements. They showed the annual and diurnal variability of temperature inversions, but most of them did not investigate the multi-annual trends in the occurrence of temperature inversions. Due to the relationship between meteorological conditions and air quality, it is important to study the multi-annual, annual and diurnal variability of air temperature inversions. The main aim of this article is to determine the multi-annual variability of air temperature inversions in Cracow and its relation to synoptic situation. Moreover, the annual and diurnal variability of temperature inversions is shown. The study is based on data derived from NCEP - NCAR reanalysis and the classification of synoptic situation types by T. Niedźwiedź. In this paper two parameters of inversions are presented – frequency and intensity. The study confirmed that the frequency and intensity of inversions have annual and diurnal variation. Multi-annual changes in the numbers of days with temperature inversion were also observed – a statistically significant increase in the 1000 – 925 hPa layer as well as in the intensity of temperature inversions – a statistically significant increase in the 1000 – 925 hPa, 1000 – 850 hPa and 925 – 850 hPa layers. It was proved that a very strong relationship exists between the days with temperature inversion and the anticyclonic situation, especially with the air-flow from south, south-west and south-east.

Opis:
Pine wood nematode (Bursaphelenchus xylophilus) (Aphelenchida: Parasitaphelencidae) is one of the most harmful agents in coniferous forests. The most important vectors of pine wood nematode are considered to be some Monochamus species (Col.: Cerambycidae), which had been forest insects with secondary importance before the appearance of B. xy- lophilus. However, the continuous spreading of the nematode has changed this status and necessitated detailed biological and climatological investigation of the main European vec- tor, Monochamus galloprovincialis. The potential distribution area of M. galloprovincialis involves those areas where the risk of the appearance of pine wood nematode B. xylophilus is significant. The main objective of our analysis was to obtain information about the in- fluencing effects of North Atlantic Oscillation (NAO) on the potential European range of B. xylophilus and its vector species M. galloprovincialis based on the connection between the mean temperature of July in Europe, the distribution of day-degrees of the vector and the NAO index. Our assessment was based on fundamental biological constants of the nematode and the cerambycid pest as well as the ECMWF ERA5 Global Atmospheric Rea- nalysis dataset. Our hypothesis was built on the fact that the monthly mean temperature had to exceed 20°C in the interest of an efficient expansion of the nematode. In addition, the threshold temperature of the vector involved in the calculations was 12.17°C, while the accumulated day-degree (DD) had to exceed the annual and biennial 370.57°DD for univoltine and semivoltine development, respectively. Our finding that a connection could be found between a mean temperature in July above 20°C and NAO as well as between the accumulated day-degrees and NAO can be the basis for further investigations for a reliable method to forecast the expansion of pine wood nematode and its vector species in a given year.

Opis:
The limitation in approachability to rainfall data sources with an appropriate spatial-temporal distribution is a significant challenge in different parts of the world. The development of general circulation models and mathematical algorithms has led to the generation of various rainfall products as new sources with the potential to overcome the shortage in datascarce basins. In this study, the performance of the PERSIANN-CCS and CMORPH satellite-based rainfall product, as well as the ERA5 and ERA-Interim reanalysis, was evaluated based on detection skill and quantitative metrics in a daily, monthly and seasonal time scales in the Dez basin located in the southwest of Iran. The basin has a wide topographic variation and scattered rain gauge stations. Overall results denote that the ERA5 dataset has the best performance in all statistic verification than other rainfall products. Based on the daily evaluation of all rainfall products, the false alarm rate (FAR) is higher than 0.5, so none of the datasets could capture the temporal variability of rainfall occurrence. This study has covered the western parts of the Zagros steep slopes in which the topographic conditions have a significant effect on the activity of rainfall systems. On a monthly scale, the mean value of the correlation coefficient (CC) for ERA5, ERA-Interim, PER-SIANN-CCS, and CMORPH was equal to 0.86, 0.85, 0.51, 0.39, respectively. The results of seasonal evaluation suggested that all datasets have better rainfall estimation in autumn and winter, and the capability of all datasets dramatically decreased in the spring. The current paper argues that the ERA5 reanalysis typically outperforms ERA-Interim and can be considered as a reliable rainfall source in the future hydrological investigation in the southwest of Iran.

Opis:
When designing structures, it is often necessary to re-analyse a structure that is different in some parts from the original one. As real structures are often complex, their analysis is therefore very challenging. In such cases, reanalysis methods are advantageously used. The aim of this paper is to approach the problem of solving the constructions using reanalysis method in which the time taken in solving algebraic equations is reduced. In particular, the purpose of this work is to demonstrate on a chosen system the time savings and the advantages of the chosen direct efficient reanalysis method for a given design problem. A basic condition for meeting these criteria is the modernization of computational procedures in the mechanics of compliant solids.

Artykuł jest wstępem do zbioru prezentowanych w tym numerze tekstów na temat różnych sposobów i możliwości powtórnego wykorzystania materiałów pochodzących z jakościowych badań społecznych. Zastanawiamy się, jak taka powtórna analiza wpływa na pogłębienie refleksji metodologicznej na temat działalności badawczej w terenie, statusu samych danych i kontekstów ich wytwarzania oraz tworzonej na ich podstawie wiedzy socjologicznej. Próbujemy również podsumować sześć lat działalności Archiwum Danych Jakościowych przy IFiS PAN oraz opisać zmiany, jakie dokonały się w tym czasie w podejściu do dzielenia się materiałami badawczymi zarówno u nas w kraju, jak i za granicą.
The article is an introduction to the collection of texts presented in this issue on various prospects and opportunities for re-using data from qualitative social research. We reflect on how such re-analyses influence the deeper thinking about methodological issues connected to research activity in the field, the status of the data and the contexts of their production and the character of sociological knowledge created on their basis. We are also trying to summarise the six years of activity of the Qualitative Data Archive at the IFiS PAN and describe the changes that have taken place at this time in the approach to sharing research data both in Poland and abroad.

Opis:
This article discusses the theoretical and methodological arguments for the archivization of qualitative data in the social sciences, particularly sociology. These arguments are preceded by the presentation of selected research and documentary undertakings (including film) that consist in a return to specific persons and places (or data) after an interval of some years by the same researchers or their successors. Ethnographic revisits are a specific kind of such return. The author reviews and systematizes revisitations in the conviction that the theoretical tools and methodological approaches that have been worked out there—with the characteristic autoreflexiveness of contemporary anthropology—can be used at least in part in new qualitative analyses of sociological data in archives, including the Qualitative Data Archive of the Polish Academy of Sciences’ Institute of Philosophy and Sociology.
