Dr. Ambrasat erforscht die Karrieren und Arbeitsbedingungen von Wissenschaftlern und Hochschulabsolventen in Deutschland, insbesondere wie soziale Beziehungen, Beschäftigungssicherheit und Zufriedenheit ihre berufliche Entwicklung beeinflussen. Aktuell leitet er das Projekt TransferSurvey (2025–2029), das untersucht, wie wissenschaftliche Erkenntnisse in die Praxis transferiert werden. Seine Arbeiten basieren auf großen Längsschnittstudien (DBKH-Studie, Nacaps, Scientist Survey) und kombinieren quantitative Befragungen mit qualitativen Analysen. Für Forschungseinrichtungen, Hochschulen und Forschungspolitik liefert er evidenzbasierte Erkenntnisse zur Optimierung von Arbeitsbedingungen, Nachwuchsförderung und Wissenstransfer.

We investigate intrasocietal consensus and variation in affective meanings of concepts related to authority and community, two elementary forms of human sociality. Survey participants (n = 2,849) from different socioeconomic status (SES) groups in German society provided ratings of 909 social concepts along three basic dimensions of affective meaning. Results show widespread consensus on these meanings within society and demonstrate that a meaningful structure of socially shared knowledge emerges from organizing concepts according to their affective similarity. The consensus finding is further qualified by evidence for subtle systematic variation along SES differences. In relation to affectively neutral words, high-status individuals evaluate intimacy-related and socially desirable concepts as less positive and powerful than middle- or low-status individuals, while perceiving antisocial concepts as relatively more threatening. This systematic variation across SES groups suggests that the affective meaning of sociality is to some degree a function of social stratification.

The concept of habitus refers to socially stratified patterns of perception, classification, and thinking that are supposed to bring about specific lifestyles. Until now, research on the links between stratification and lifestyles has accounted for the habitus mainly in conceptual and theoretical terms, and studies directly measuring habitus and its association with stratification and lifestyles are rare. The present study conceptualizes the habitus as an individual‐level pattern of meaning making and suggests an operationalization that is commonly used in identity research. Using survey data of 3,438 respondents, the study investigates associations between different lifestyles and patterns of meaning making. Results show, first, that self‐related meanings vary systematically across lifestyle categories and mirror respondents' stratification position. Second, the meanings of various social concepts also vary significantly across lifestyle categories and partly reflect descriptive lifestyle characteristics. In sum, the study presents a plausible operationalization of (parts of) the habitus and advances our understanding of its mediating position between stratification and lifestyles.

The introduction of structured doctoral programs (SDPs) is changing the conditions of doctoral training in Europe and worldwide. SDPs were introduced to reorganize doctoral training to make it more transparent and to improve the quality of doctoral training and supervision. This article suggests a conceptual framework to assess the outcome of these goals against the backdrop of existing pathways toward the doctorate, namely, the doctoral status group research assistants, scholarship holders, and external candidates. Based on empirical data from the large longitudinal study on doctoral candidates in Germany, ProFile, we describe the amount of structuration and formalization within those status groups and compare it to the structure of SDPs. Results reveal that traditional status groups already structure the context of doctoral training remarkably. In front of this backdrop, SDPs change the landscape in the expected way by improved transparency, course offers, and increased exchange with the supervisor. However, the effects of SDP membership vary between traditional status groups; thus, not all status groups profit to the same degree. We conclude that the structure of doctoral training has diversified through the introduction of SDPs and provides an outlook on the changes that can be expected if the number of SDPs increases.
