Aim Understanding interrelations between the factors predicting students’ aggressive behavior is a priority for bullying-prevention programs. Our study explores two possible mechanisms linking school disciplinary structure and students’ aggression. We test students’ moral disengagement and bullying by teachers as mediational pathways from school au...

This article looks into methodological issues in the assessment of bullying, providing cross-national bullying statistics and discussing the possible causes of essential variation in prevalence rate estimates. Individual- and school-level characteristics of bullying are described based on the results of a large-scale representative survey of school...

Objectives To measure the effects of peer influence and peer selection on drinking behavior in adolescence through a rigorous statistical approach designed to unravel these interrelated processes. Methods We conducted systematic searches of electronic databases, thesis collections and conference proceedings to identify studies that used longitudin...

School tracking is defined as the placement of students into different school types, hierarchically structured by performance. In the majority of OECD countries, tracking takes place at the age of 15 or 16. In Russia, similarly, students are sorted into “academic” (high school) and “non-academic” (vocational training) tracks after Grade 9, at the a...

Introduction Alcohol consumption is a considerable public health problem that is especially harmful to young people. To develop effective prevention programmes targeted at adolescents, it is important to understand the social mechanisms triggering alcohol consumption. Among such mechanisms, peer influence plays an important role. The effects of pee...

The project "Women Data Science Leaders in Russia" aims to increase gender diversity and women's participation in the Russian data science community by means of developing online courses and video materials that present female role models for female students, in order to change the stereotypes that affect the perception of the data science field.

This paper uses representative student data from St. Petersburg, Russia to analyze school segregation by parental socioeconomic status and student academic performance. The proposed systematic segregation indices account for ordinal variables and take expected segregation into account. We decompose segregation by school type, school, and classes an...

We apply social network analysis to examine school choice in the second-largest Russian city Saint-Petersburg. We use online data (“digital footprints”) of between-schools comparisons on a large school information resource shkola-spb.ru. This resource allows to identify clusters of city schools that have been compared to each other more often and t...

Sixty-two semi-structured interviews with students of grades 9-11 in 15 schools and a survey of 2,376 ninth-graders from 55 schools were used to identify Russian teenagers' perceptions of popularity and assess gender differences in the factors of popularity. It transpires that 40-50% of school students reject the very notion of "popular" as inequal...

This article explores the relationship between educational outcomes and anti-school attitudes at different levels of social organization in schools. Data were collected in St. Petersburg, Russia (104 schools, 7300 students) and analyzed using multi-level regression models that included three levels: individual, clique of friends and school. A cliqu...

The authors examine the digital divides of the first and second levels and analyze the use of educational resources by Russian schoolchildren. Several specialized educational resources for schoolchildren are described. The first level digital divide is understood as unequal access to the Internet among different social groups; the second level digi...

Working-class educational paths tend to be associated with elevated drinking. Little research has examined whether disproportionate alcohol use among vocationally oriented youth begins before or after the start of their vocational education. The present study analyzes a large sample of Russian middle-school students (N = 1269; mean age = 14.9), com...

This study investigates whether antipathy in the middle-school classroom has anything to do with ethnic status, migration history or academic achievements. The objective of this study is to examine whether or not these criteria lead adolescents to exclude certain peers from their social circle. The data for analysis was collected during a survey of...

The present study examines structural and socio-psychological factors affecting attitudes towards quitting profession among school teachers. We explore effects of perceived workplace difficulties, employment opportunities, self-efficacy beliefs, and emotional attachment to teaching profession. The survey was conducted among public secondary school...

In this paper we explore motivational structure of students taking a challenging university course. The participants were second-year undergraduate students majoring in Economics, Sociology, Management and Humanities, enrolled in the Data Science minor. Using expectancy-value theory as a framework, we aim (1) to analyze gender differences in motiva...

Academic help-seeking and help-providing in school setting streamlines learning process and advances social competencies among students. Little research has examined differential patterns of help-seeking among students of ethnic minority and non-minority status. The present study conceptualizes school help-providing as remedial exchange of social c...

This study analyses the relationship between aggressive behavior of adolescents and their social status among peers. The data was collected in 2013–2014 in four vocational schools of St Petersburg (in total 418 students, mean age 17–18 years old). For comprehensive study of adolescents environment all second year students were surveyed. It was demo...

Through the last 25 post-Soviet years with the rise of economic inequality, Russian school system became highly stratified, and numerous studies have demonstrated that so called 'elite∗ schools (i.e. schools with advanced curriculum - gymnasiums, lyceums, specialized schools) are very different from schools with standard curriculae. The differences...

In this study, we analyze self-reported development experience of adolescents involved in various extracurricular activities. We surveyed a large number of students (9th grade) across several regions of the Russian Federation: St. Petersburg and the Leningrad region, Tomsk and Tomsk region, and Pskov. The total number of respondents was 3367. The s...

Data on ethnic diversity and ethnicity/migration correlation among primary and secondary school students is presented in the article for the first time ever. The study is based on polls held among 21,320 school students in 365 schools of five regions of Russia (Moscow Oblast, Saint Petersburg, Leningrad Oblast, Tomsk, and Pskov). The most part of s...

The paper presents the results of a large-scale study on the scope of extracurricular education services and an assessment of the potential role of education outside the classroom and informal education in solving children's socialization issues. The study was carried out by questioning students as consumers of education services. A new instrument...

This article analyzes student pro-school/anti-school attitudes on different levels and explores their relation to educational outcomes. We examine the individual level, school level, and clique level predictors (clique is defined as a tight social group within a class social network). Cliques were identified using special software called Kliquefind...

This study investigates how the sociometric popularity of schoolchildren is related to individual academic achievements in a context of different levels of academic culture and educational aspirations in the classroom. The sample includes 5058 students in 270 classes from 98 schools in St. Petersburg. To examine class-level effects, we employ multi...

Currently, three genotypes of hepatitis delta virus (HDV) are described. The most common, genotype I, has a worldwide distribution; in contrast, genotype II has been found previously only in Japan and Taiwan, while genotype III is found exclusively in South America. Considering the high prevalence of HDV in Northern Siberia (Russia), restriction fr...

Hepatitis delta virus antigen was isolated from a patient by reverse transcription and polymerase chain reaction. Gel-purified cDNA was cloned in E. coli expression vectors. High expression of the recombinant HDAg in bacteria was observed. The minor and major forms of HDV antigens were simultaneously expressed in bacterial strains carrying SupE mut...

Genome RNA of hepatitis Delta virus (HDV) was isolated from the blood sera of 4 independently infected patients. The genome fragment of 901-1265 was obtained for each isolate by the RT-PCR. The resultant sequences showed that all isolates belonged to HDV genotype I. Russian isolates were shown to be closely related to an Italian one (98.1-97.5% and...

Three Russian enzyme immunoassay kits for the detection of antibodies to hepatitis D virus (delta virus) in the blood serum were compared. Labsystems test kit was the control. Two of the examined kits were found sufficiently sensitive and specific, comparable with those of the imported agent.

Patients with HBsAg-positive hepatitis were screened for antibodies to HDV and HCV. The incidence of anti-HDV was 12.5% in a sample of 265 patients. The values differed appreciably in men and women, patients with chronic and acute hepatitis, narcomaniacs and subjects taking no narcotics. Antibodies to HDV were more incident in anti-HCV-positive tha...

Human recombinant interleukin 2 produced by Escherichia coli gives rise to oligomeric forms that are stable to complete denaturation. The appearance of these forms is preceded by the formation of oligomers sensitive to reduction. These processes depend on the cell status and seem to be associated with aggregation of the reaction product.

A new class of cellular proteins named "molecular chaperones" has been described recently. Chaperones prevent from improper interactions either within or between polypeptide chains, which could produce incorrect structures. Chaperones assist in assembly or disassembly of oligomeric structures and in protein transport across membranes. There are thr...

The expression of the human IL-2 recombinant gene in E. coli cells was studied. The processes which take place during thermo-induced expression and effect the state of the product were investigated. Experimental data on the membrane localisation of IL-2, the formation of aggregates (inclusion bodies) and polymers were obtained. It was determined th...
