Career studies literature suggests that careers become more boundaryless and more global. Students, the agents of the choice of career, are not a homogeneous cohort anymore. We add to the discussion the students' typology proposition for the career choice to further develop the graduate employability discourse. We make the first attempt to develop a student global vs local career taxonomy to contribute into understanding of graduate employability and career decision making. Our contribution offers a two-dimensional taxonomy, with one dimension being a type of student and another dimension being a career destination. The conceptual taxonomy is empirically tested with data from more than 400 business and economics students. We show that a global career choice would prevail above a local career choice for each of the student types. Our findings contribute into deeper understanding of career decision making and broadens our comprehension of the variety of global vs local careers for graduate employability. The study develops the future research agenda for career development researchers and multinational corporations' (MNC) practitioners and practical agenda for teaching and learning in universities.

A descriptive bibliometric analysis of works on artificial intelligence (AI) in science education is provided in this article to help readers understand the state of the field's research at the time. This study's main objective is to give bibliometric data on publications regarding AI in science education printed in periodicals listed in the Scopus database between 2002 and 2023 end of May. The data gathered from publications scanned and published within the study's parameters was subjected to descriptive bibliometric analysis based on seven categories: number of articles and citations per year, countries with the most publications, most productive author, most significant affiliation, funding institutions, publication source and subject areas. Most of the papers were published between 2016 and 2022. The United States of America, United Kingdom, and China were the top-3 most productive nations, with the United States of America producing the most publications. The number of citations to the publications indexed in Scopus database increased in a progressive way and reached to maximum number in 2022 with 178 citations. Most productive author on this topic was Salles, P. with four publications. Moreover, Carnegie Mellon University, University of Memphis, and University of Southern California have the maximum number of publications as affiliations. The National Science Foundation was the leader funding institution in terms of number of publications produced. In addition, "Proceedings Frontiers in Education Conference Fie" have the highest number of publications by year as a publication source. Distribution of the publications by subject area was analyzed. The subject areas of the publications were computer sciences, social sciences, science education, technology and engineering education respectively. This study presents a vision for future research and provides a global perspective on AI in science education.

Communication style refers to the distinct ways individuals exhibit verbal, paraverbal, and nonverbal communication patterns in social interactions. It involves receiving, interpreting, and delivering feedback and messages. Factors like culture and personality affect communication styles, and tools like communication styles inventory (CSI) help evaluate and improve individuals' communication skills. Cultural differences significantly impact communication styles, so it's important to adapt and validate measurement instruments for diverse cultural settings, such as adapting CSI for the Russian context. This study aims to adapt CSI for use in the Russian context. The research follows a quantitative approach, collecting data from 407 undergraduate and graduate students across different universities. CSI is a questionnaire assessing six distinct communication patterns with 96 items. The researchers conducted exploratory and confirmatory factor analyses to examine CSI's validity and reliability in the Russian context. The analyses yielded an eight-factor model explaining 59.5% of the total variance. Although two factors from the original scale were preserved, other factors were newly named. The confirmatory factor analysis tested the relationship between the original sub-dimensions and the new dimensions, resulting in a better-adapted model with significant relationships between items and factors. The findings indicate the scale's suitability for different cultures and sample groups, supporting its validity and reliability. Further research should adapt the scale to other cultures and utilize it in studies in the Russian context.

Atmospheric precipitation acts as a significant pathway for pollutants from the atmosphere to the Earth’s surface, and analyzing urban precipitation data on intensity, fallout regime, transfer patterns, and solid particle content helps identify pollution sources. For the first time in the Moscow megacity, the levels of soluble forms of potentially hazardous elements (PHEs) in atmospheric precipitation were studied during the whole summer season of May–September 2019. The concentrations of Al, As, B, Ba, Be, Bi, Cd, Ce, Co, Cu, Fe, La, Li, Mn, Ni, P, Pb, Rb, Sb, Sn, Sr, and Zn were determined using inductively coupled plasma mass spectrometry and atomic emission spectroscopy methods. The research underscores the crucial role of atmospheric precipitation in washing PHEs out of the atmosphere. In May and September, concentrations of PHEs surpass the warm-season average. Notable contamination in May stems from elevated traffic during vacations, extensive burning of plant debris and wood, and pollen transport. Summer months are characterized by reduced forest and agricultural fires, traffic, and increased vegetation, leading to lower PHE concentrations, especially in July, with typical amount of precipitation contributing to pollutant dispersion. Elevated PHE levels in September are observed due to increased traffic load, biomass burning, and the expansion of unvegetated soil areas. Rainwater is enriched with Sb, Pb, Cd, Zn, Cu, B, Bi, P, and Sr, sourced from vehicle emissions, soil particles, industry, construction dust, biomass burning, and forest fires. Moderate enrichment with Ba, Mn, Ni, Co, and Sn also occurs episodically. Regression analysis highlights solid particles’ role as a major PHE source in rainwater, with the longer antecedent dry periods and the higher acidity level of rain intensifying the accumulation of PHEs. Long-range transport plays a lesser role, with Southern and Northern Europe, Western Siberia, and the central part of European Russia contributing meaningfully.

For the first time, polycyclic aromatic hydrocarbons (PAH) contamination of the soil cover of Ulan-Ude, the capital of the Republic of Buryatia, was studied. The content of 16 individual polyarenes was analyzed in the upper horizon of background chestnut and urban soils, sampled during soil and geochemical survey in July–August 2022. The average concentration of total PAHs in the soil cover of Ulan-Ude was 735 ng/g, which was 8 times as much as the concentration in the background soils (87 ng/g). The PAH amount in the soil of various functional zones decrease in the following order: railway transport > motor traffic > industrial > one-story residential > multi-story residential > recreational. At the same time, the amount of PAHs in the railway transport zone was 2.6–5.2 times higher than in other functional zones, which indicates that railway transport is the most powerful source of PAHs in the city. Contamination of soils with polyarenes in all functional zones is determined primarily by medium- (46%) and high-molecular-weight (41%) compounds. Among PAHs with low molecular weight, phenanthrene prevailed (9% of the total PAHs), but medium-molecular-weight fluoranthene (18%) and pyrene (13%) showed higher share; high-molecular-weight compounds dominated by benzo(ghi)perylene (12%), benzo(b)fluoranthene (10%), indeno(1,2,3-cd)pyrene (8%) and benzo(a)pyrene (6%). The total amount of 16 PAHs in the soil cover of the city varied within the range of 17–9 540 ng/g. The highest levels of pollution (3 226–9 540 ng/g) were recorded at 9 sampling points (4% of the city), which form the most contrasting local PAH anomalies. In more than half of the territory of Ulan-Ude, the total amount of PAHs did not exceed 500 ng/g. The indicator ratios of individual PAHs made it possible to determine the dominant types of sources, which include railway transport and coal combustion. The contribution to the environmental hazard of soil contamination with PAHs in Ulan-Ude was mainly made by benzo(a)pyrene (64%) and, to a lesser extent, by benzo(b)fluoranthene (9.6%), indeno(1,2,3-cd)pyrene (7.2%), dibenzo(ah)anthracene (6.5%) and benzo(a)anthracene (6.1%).

The concept of "Classroom climate" has a broad semantics. It covers the quality of interaction not only between students and teachers, but also with classmates at the managerial, social, emotional and academic levels. It is shown that students' subjective perception of the classroom climate carries their behavior, psychological well-being and success in teaching students, as well as their personal characteristics, the development of abilities and giftedness. The use of an evidence-based approach in education improves the quality of psychological tools used in different regions of the Russian Federation and other countries. The article reflects the standardization of the questionnaire "Climate in the classroom" in the Republic of Belarus. The study sample consisted of 425 school students from different regions of the Republic of Belarus (Minsk, Rogachev and Zhlobin) aged 10-18 years (54,35% female). The average age was 15±1 years (median=15 years). Using confirmatory factor analysis, the six-factor structure of the questionnaire was statistically validated, and its structure demonstrated satisfactory alignment with the empirical data. The Cronbach's alpha coefficient confirms the internal consistency of the scales, with their mutual correlations being at a moderate level. The magnitude and direction of the relationships are consistent with the expected outcomes. The convergent and differential validity of the questionnaire scales has been tested on the scales of the Multidimensional Life Satisfaction Scale (SHUJI) and academic performance. The questionnaire is recommended to school psychologists and teachers for psychological and pedagogical support of students from different age groups to create a favorable school environment.

Abstract The Light-oxygen-voltage-sensing domain (LOV) superfamily, found in enzymes and signal transduction proteins, plays a crucial role in converting light signals into structural signals, mediating various biological mechanisms. While time-resolved spectroscopic studies have revealed the dynamics of the LOV-domain chromophore’s electronic structures, understanding the structural changes in the protein moiety, particularly regarding light-induced dimerization, remains challenging. Here, we utilize time-resolved X-ray liquidography to capture the light-induced dimerization of Avena sativa LOV2. Our analysis unveils that dimerization occurs within milliseconds after the unfolding of the A’α and Jα helices in the microsecond time range. Notably, our findings suggest that protein-protein interactions (PPIs) among the β-scaffolds, mediated by helix unfolding, play a key role in dimerization. In this work, we offer structural insights into the dimerization of LOV2 proteins following structural changes in the A’α and Jα helices, as well as mechanistic insights into the protein-protein association process driven by PPIs.

Soil mapping of urban areas is required for solving many applied problems. However, its methodology is still under development. The lack of information about urban soils and the inconsistence of their classifications are the main difficulties, as well as the intricate soil cover patterns in cities and towns. The research was aimed to compile the soil map for the drainage basin of the small urban river Setun at a scale that could reflect its soil cover heterogeneity. Some new approaches to the differentiation of urban and semi-urban soils in accordance with recent ideas on their systematic and land use variants have been proposed. The concept of pedo-urbo-mosaics, which implements the soil cover pattern theory in relation to urbanized territory, has been used for delineating mapping units. The compilation methodology involved the use of open spatial data and GIS technologies. The subdivision of the basin into mapping units was performed using ©OpenStreetMap data and Yandex Maps Web mapping service. Spatial analysis in GIS allowed for mapping the territory with a moderate urbanization rate on a large scale, obtaining a more adequate and detailed spatial representation of the area than in the case of applying the traditional approach. The map, at a scale of 1:60,000 contains 16 natural/semi-natural soils and technogenic superficial formations, as well as 11 pedo-urbo-mosaics. The study may be of methodological interest as an experience in soil mapping of urbanized areas using GIS.

Abstract Understanding protein structure and kinetics under physiological conditions is crucial for elucidating complex biological processes. While time-resolved (TR) techniques have advanced to track molecular actions, their practical application in biological reactions is often confined to reversible photoreactions within limited experimental parameters due to inefficient sample utilization and inflexibility of experimental setups. Here, we introduce serial X-ray liquidography (SXL), a technique that combines time-resolved X-ray liquidography with a fixed target of serially arranged microchambers. SXL breaks through the previously mentioned barriers, enabling microgram-scale TR studies of both irreversible and reversible reactions of even a non-photoactive protein. We demonstrate its versatility in studying a wide range of biological reactions, highlighting its potential as a flexible and multi-dimensional assay framework for kinetic and structural characterization. Leveraging X-ray free-electron lasers and micro-focused X-ray pulses promises further enhancements in both temporal resolution and minimizing sample quantity. SXL offers unprecedented insights into the structural and kinetic landscapes of molecular actions, paving the way for a deeper understanding of complex biological processes.

Obstetric pathology (pregnancy loss at different gestational ages; premature delivery of morphologically normal foetus due to pre-/eclampsia or placental insufficiency), along with thrombotic complications are the main clinical manifestations of antiphospholipid syndrome (APS). Among arterial thromboses in APS, cerebral vascular thromboses in the form of strokes or transient ischaemic attacks. Patients with APS have a well known increased risk of thrombosis associated with pregnancy or conditions accompanied by hyperestrogenemia. More than half of thrombotic complications in women with APS occur during gestation or hyperestrogenemia. Most studies of pregnancy in APS have focused on women with recurrent fetal loss, and data on pregnancy outcomes in patients with other clinical phenotypes of APS, such as thrombotic APS, are limited. We present a case report of a patient with reliable thrombotic APS (with recurrent ischaemic cerebral circulatory disorders) and highly positive levels of antiphosphrolipid antibodies with a favourable pregnancy outcome.

BackgroundThe molecular effects of intermediate and long-term exposure to air pollution and temperature, such as those on extracellular microRNA (ex-miRNA) are not well understood but may have clinical consequences.ObjectivesTo assess the association between exposure to ambient air pollution and temperature and ex-miRNA profiles.MethodsOur study population consisted of 734 participants in the Normative Aging Study (NAS) between 1999 and 2015. We used high-resolution models to estimate four-week, eight-week, twelve-week, six-month, and one-year moving averages of PM2.5, O3, NO2, and ambient temperature based on geo-coded residential addresses. The outcome of interest was the extracellular microRNA (ex-miRNA) profile of each participant over time. We used a longitudinal quantile regression approach to estimate the association between the exposures and each ex-miRNA. Results were corrected for multiple comparisons and ex-miRNAs that were still significantly associated with the exposures were further analyzed using KEGG pathway analysis and Ingenuity Pathway Analysis.ResultsWe found 151 significant associations between levels of PM2.5, O3, NO2, and ambient temperature and 82 unique ex-miRNAs across multiple quantiles. Most of the significant results were associations with intermediate-term exposure to O3, long-term exposure to PM2.5, and both intermediate and long-term exposure to ambient temperature. The exposures were most often associated with the 75th and 90th percentile of the outcomes. Pathway analyses of significant ex-miRNAs revealed their involvement in biological pathways involving cell function and communication as well as clinical diseases such as cardiovascular disease, respiratory disease, and neurological disease.ConclusionOur results show that intermediate and long-term exposure to all our exposures of interest were associated with changes in the ex-miRNA profile of study participants. Further studies on environmental risk factors and ex-miRNAs are warranted.

В статье, посвященной образу действий и коммуникации людей в общественных местах российского города XVIII в. (на рынках, в кабаках, в банях, на постоялых дворах, и др.), основное внимание уделено поведению людей в храмах. В них проходили события местного значения (свадьбы, крестины, отпевания и др.), а также осуществлялась коммуникация власти с подданными (принесение присяг, чтение указов и проч.). Церковное пространство показано как место социальной и гендерной напряженности, усугубленной в петровское время «реформой благочестия». Единство православного сообщества нарушалось старообрядцами, иноземцами иных конфессий, сторонниками и противниками петровских реформ, «неблагочестивыми» православными, сталкивавшимися в храме. Церковное пространство оказывалось перенасыщенным людскими впечатлениями, эмоциями и информацией. Однако, хотя некоторые здесь и осмеливались выражать недовольство властью, но лишь эмоционально, потому назвать церковное пространство публичным в том смысле, который ему придал Ю. Хабермас, по мнению автора, невозможно.

In this paper, we consider the possibility of using inexpensive and effective sorption materials based on plant raw materials, such as fruit rind, vegetable waste, fallen leaves, and the use of phytosorbents for the purification of sewage containing heavy metals and petroleum products. The use of vegetable waste for the manufacture of sorbents is a priority for solving environmental problems. It is suggested to use residual biomass as a sorption material, which is formed after extraction of lipids from C. sorokiniana microalgae and duckweed Lemna minor. To increase the sorption capacity, it was proposed to thermally modify the residual biomass. The optimum heat treatment conditions were 450 °C for 20 minutes with limited access to oxygen. The obtained biomass allows one to extract ions of heavy metals with efficiency of 91-93% for ions of lead, cadmium, zinc and copper. To increase the sorption capacity (A, mg/g) of the residual biomass, heat treated waste from the agro-industrial complex and chitosan were proposed as additives. The addition of chitosan makes it possible to obtain a sorption material in the form of granules, which is convenient to use. For the sorption materials obtained, microstructural studies were carried out, which allowed us to substantiate the sorption properties of the materials. The physical and mechanical properties of sorbents, such as abrasion, grindability, allow us to offer new materials for use on an industrial scale. In the article, a technological scheme for obtaining sorption materials from residual biomass is given.
