The article presents a research project investigating the biographical experiences of upward mobility and class reproduction. The project involved biographical-narrative interviews with academics, artists, and business managers who had experienced intergenerational upward mobility over the course of their lives or who were following in the career paths of at least one of their parents. The article focuses on methodological aspects. Drawing on the principles of reflexive sociology, particular attention is given to the role of the researchers’ positionality throughout the research process and the need to continuously contextualize it in the course of teamwork. Given the focus of the research on class and biography, it is important to consider class in a rigorous manner as a key category influencing the situation of the biographical interview, the interpretation of the collected material, the emotional labor of the researchers, and the dynamics of the research team.
The primary objective of this article is to demonstrate the impact of collective identities and communitarian elements on the processes of law application in contemporary Central Europe. The analyses are conducted against the backdrop of a dispute resolved nearly a decade ago by the Latvian Constitutional Court, which, in essence, represented a clash between the language of individual rights and the language of community interests. To verify the hypothesis concerning the influence of values defined as communitarian on final Judicial decisions – with particular emphasis on the reasoning underlying these decisions – the Latvian dispute, serving as the point of departure, is situated within a broader regional context and examined through the lens of Martin Loughlin’s concept of ‘invisible constitution’.

This article explores how Brexit has reversed migration trends shaped by Poland’s 2004 EU accession, focusing on young adults aged 19–34. Using data from the Polish Labour Force Survey (2015–2019) and the Migrant Selectivity Index (MSI), it traces shifts in the socio-demographic profiles of Polish migrants. Key findings include a masculinisation of migration flows, a decline in tertiary-educated migrants, and growing mobility among individuals with intermediate education from ru ral areas—patterns resembling pre-accession dynamics. These changes reflect labour market realignments, with Germany surpassing the UK as the top destination. The study argues that Brexit not only disrupted post-accession migration but reactivated older selectivity mechanisms, reshaping human capital flows within the EU. By quantifying selectivity, it offers new insights into how geopolitical shifts affect labour mobility, regional development, and transnational skill distribution.
The same dataset can be analysed in different justifiable ways to answer the same research question, potentially challenging the robustness of empirical science1,2,3. In this crowd initiative, we investigated the degree to which research findings in the social and behavioural sciences are contingent on analysts’ choices. We examined a stratified random sample of 100 studies published between 2009 and 2018, in which, for one claim per study, at least five reanalysts independently reanalysed the original data. The statistical appropriateness of the reanalyses was assessed in peer evaluations, and the robustness indicators were inspected along a range of research characteristics and study designs. We found that 34% of the independent reanalyses yielded the same result (within a tolerance region of ±0.05 Cohen’s d) as the original report; with a four times broader tolerance region, this indicator increased to 57%. Of the reanalyses conducted, 74% reached the same conclusion as the original investigation, 24% yielded no effects or inconclusive results and 2% reported the opposite effect. This exploratory study indicates that the common single-path analyses in social and behavioural research should not be simply assumed to be robust to alternative analyses4. Therefore, we recommend the development and use of practices to explore and communicate this neglected source of uncertainty.

Background: Citizenship behaviors are crucial in fostering social progress. This study examined the psychometric properties of the Chinese version of the Citizenship Behavior Questionnaire-30-General Version (CBQ-30-GV) among Taiwanese university students. It also examined the association of citizenship behaviors with depression and perceived stress.
Methods: A total of 1000 university students participated in an online survey. To evaluate the factor structure of the CBQ-30-GV, five competing models were examined using confirmatory factor analysis (CFA). Furthermore, internal consistency was assessed, and concurrent validity was examined by analyzing the correlations between CBQ-30-GV scores and subjective well-being, as measured using the Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment Well-being (PERMA)-Profiler. Moreover, the correlations of citizenship behaviors with depression (measured using the Center for Epidemiological Studies Depression Scale) and perceived stress (measured using the Perceived Stress Scale) were investigated using Pearson correlations.
Results: The findings supported a bifactor structure for the CBQ-30-GV, comprising seven specific factors and a general factor, with satisfactory model fit. The CBQ-30-GV demonstrated adequate internal consistency, and all seven specific and general factor scores were significantly and positively correlated with PERMA-Profiler scores (r = 0.080 to 0.490; p < 0.001). The general factor and the majority of specific factor scores of the CBQ-30-GV were significantly and negatively associated with depression (r = –0.426 to –0.135; p < 0.001) and perceived stress (r = –0.346 to –0.165; p < 0.001), whereas the factor scores for political activity and activity for change exhibited either positive or nonsignificant associations with depression and perceived stress.
Conclusions: These findings confirm the bifactor structure of the CBQ-30-GV and its acceptable internal reliability and concurrent validity. They indicate that most of the CBQ-30-GV specific factor scores negatively correlated with depression and perceived stress.
