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.

Recent research indicates that segregation is, in addition to many other undesirable consequences, negatively associated with social capital, in particular, generalized trust within a community. This study investigates whether an individual's residential neighborhood and the stereotypes associated with this neighborhood affect others’ trusting behavior as a specific form of social exchange. Using an anonymous trust game experiment in the context of five districts of the German capital, Berlin, we show that trusting is contingent on others’ residential neighborhood rather than on deliberate assessments of trustworthiness. Participants show significantly greater trust toward individuals from positively stereotyped neighborhoods with favorable sociodemographic characteristics than to persons from negatively stereotyped neighborhoods with unfavorable sociodemographics. Importantly, when stereotypes and sociodemographic factors point in opposite directions, participants’ trust decisions reflect stereotype content.

Self-reported measures of health are generally treated as weak measures of respondents' objective health status. On the other hand, most surveys use self-reported health to measure health status and to determine the effects of a range of other socio-economic characteristics of the local environment on individual health. It is therefore of interest to the public health research community to verify the validity of self-reported health data. We do this by analyzing data from a longitudinal household panel survey: the German Socio-Economic Panel Study (SOEP). In 2006, and again in 2008, hand grip strength was measured as part of the SOEP. The hand grip data can be compared with other indicators of health and well-being from the SOEP survey. In a first step, we examine short-term mortality outcomes predicted by changes in hand grip strength. Then we compare the predictive power of the results with those of a subjective indicator of well-being: overall life satisfaction. We find that both measures are related to mortality risk. However, the effects are quite independent. Thus we argue that changes in hand grip strength and overall life satisfaction capture two different aspects of health status and its changes. We therefore test this hypothesis by correlating the indicators with other survey-based health measures that were also taken in the SOEP in 2006 and 2008.

Promoting translational research as a means to overcoming chasms in the translation of knowledge through successive fields of research from basic science to public health impacts and back is a central challenge for research managers and policymakers. Organizational leaders need to assess baseline conditions, identify areas needing improvement, and to judge the impact of specific initiatives to sustain or improve translational research practices at their institutions. Currently, there is a lack of such an assessment tool addressing the specific context of translational biomedical research. To close this gap, we have developed a new survey for assessing the organizational climate for translational research. This self-assessment tool measures employees' perceptions of translational research climate and underlying research practices in organizational environments and builds on the established Survey of Organizational Research Climate, assessing research integrity. Using this tool, we show that scientists at a large university hospital (Charité Berlin) perceive translation as a central and important component of their work. Importantly, local resources and direct support are main contributing factors for the practical implementation of translation into their own research practice. We identify and discuss potential leverage points for an improvement of research climate to foster successful translational research.

Nach dem Erhebungsjahr 2006 wurde 2008 zum zweiten Mal die Stärke der Handgreifkraft bei einem Teilsample der SOEP Befragten ermittelt. Dieser Biomarker ist ein Indikator für die gesamte Muskelkraft und ist gut geeignet, um gesundheitliche Einschränkungen und Krankheiten festzustellen. Im SOEP ergänzt die Hand-Greifkraftmessung in sinnvoller Weise die verschiedenen subjektiven und generischen Gesundheitsindikatoren. Für die erste Greifkraftmessung 2006 wurden 5528 Personen rekrutiert, wovon 5.307 am Greifkrafttest teilnahmen. 4.105 der 5.307 getesteten Personen wurden 2008 wiederholt getestet. 1.437 Personen wurden erstmalig zur Greifkraftmessung herangezogen. Die Verweigerungsraten für die Greifkraft sind mit 4 % (2006) und 0 % (2008) sehr gering und geben keine Hinweise auf systematische Verzerrungen. Für 3.434 Personen liegen für beide Jahre vollständige Angaben für die linke und die rechte Hand vor, für 53 weitere Personen liegen vollständige Angaben wenigstens für die 'dominante' Hand vor. Der Bericht dokumentiert die Struktur der SOEP-TeilnehmerInnen der Handgreifkraftmessung der Jahre 2006 und 2008 und stellt deskriptive Ergebnisse der Handgreifkraftmessungen dar. Die 'Verlaufsdaten' ermöglichen zudem eine Einschätzung der Qualität der Daten und ermöglichen einen Ausblick auf die weiteren Greifkraftmessungen im Befragungsjahr 2010 und folgenden Wiederholungsmessungen.

Ever since Georg Simmel’s seminal works, social relations have been a central building block of sociological theory. In relational sociology, social identities are an essential concept and supposed to emerge in close interaction with other identities, discourses and objects. To assess this kind of relationality, existing research capitalises on patterns of meaning making that are constitutive for identities. These patterns are often understood as forms of declarative knowledge and are reconstructed, using qualitative methods, from denotative meanings as they surface: for example, in stories and narratives. We argue that this approach to some extent privileges explicit and conceptual knowledge over tacit and non-conceptual forms of knowledge. We suggest that affect is a concept that can adequately account for such implicit and bodily meanings, even when measured on the level of linguistic concepts. We draw on affect control theory (ACT) and related methods to investigate the affective meanings of concepts (lexemes) denoting identities in a large survey. We demonstrate that even though these meanings are widely shared across respondents, they nevertheless show systematic variation reflecting respondents’ positions within the social space and the typical interaction experiences associated with their identities. In line with ACT, we show, first, that the affective relations between exemplary identities mirror their prototypical, culturally circumscribed and institutionalised relations (for example, between role identities). Second, we show that there are systematic differences in these affective relations across gender, occupational status and regional culture, which we interpret as reflecting respondents’ subjective positioning and experience vis-à-vis a shared cultural reality.

Nacaps, the National Academics Panel Study, is a new longitudinal study of doctoral candidates and doctorate holders in Germany funded by the Federal Ministry of Education and Research (BMBF). The project aims at providing nationwide cross-sectional and longitudinal data on doctoral students and doctorate holders in Germany regarding their study conditions as well as their career trajectories within and outside of academia. The Nacaps study series apply a panel design to multiple cohorts. In 2019, all doctoral students registered at 53 doctorate-granting higher education institutions as off 01.12.2018 were invited to a first survey. Further panel waves follow at yearly intervals. Topics of the survey are e.g. the kind and structure of doctoral studies, motives for conducting doctoral studies, the mentoring situation, working and employment conditions, plans for career paths after the doctorate, international mobility, as well as individual characteristics of respondents. By covering these topics and by considering important indicators on young scholars, the Nacaps data provide important knowledge for national reporting (e.g. the federal report on young academics called “Bundesbericht wissenschaftlicher Nachwuchs”), for local steering, as well as for numerous further stakeholders. Moreover, the data offer an opportunity to investigate scientific research questions in the field of academic careers.

The Covid-19 pandemic initially led to high demands for scientific expertise, while at the same time scientific results, for example in the form of preprints, being widely and sometimes critically discussed in public almost as soon as they were published. It is an open question how Scientists react and adopt to the changed situation. With data from the (German) Scientists Survey, it is possible to map the scientists' involvement in the pandemic - across academic positions and disciplines. Our results show that scientists from all disciplines are involved in corona-related research, have started or acquired projects and already published with relation to COVID-19. Social Sciences are even more involved than e.g. life science. Gender effects emerge I such a way that women actually less rapidly adopt to the new situation.

Promoting biomedical translation from bench to bedside and back in organizational settings is a central challenge for research managers and policymakers. For this, organizational leaders need to assess baseline conditions, identify areas needing improvement, and to judge the impact of specific initiatives to sustain or improve translational research practices at their institutions. Currently, there is a lack of such an assessment tool addressing the specific context of translational biomedical research. To close this gap, we have developed and tested a new survey for assessing the organizational climate for translational research. This self-assessment tool measures employees’ perceptions of translational climate and underlying research practices in organizational environments and builds on the established Survey of Organizational Research Climate. Having implemented the new survey in practice, we show that scientists at a large university hospital (Charité Berlin) perceive translation as a central and important component of their work. Importantly, local resources and direct support are main contributing factors for the practical implementation of translation into their own research practice. We identify and discuss potential leverage points for an improvement of research climate to foster successful translational research.

Absolventen von Hochschulen finden heutzutage beim Berufseinstieg einen flexibilisierten Arbeitsmarkt vor. Nur einer Minderheit gelingt die Platzierung in unbefristeten Beschäftigungsverhältnissen. Es bestehen Mobilitätsbarrieren zwischen befristeten und unbefristeten Beschäftigungsverhältnissen. Absolventen in flexibilisierten Beschäftigungsverhältnissen sind zudem hinsichtlich der Qualitäten der Jobs im Vergleich zu unbefristet Beschäftigten benachteiligt. Die Flexibilisierung des Arbeitsmarkts bewirkt eine Verschiebung der Determinanten beruflichen Erfolgs. Bestimmte berufliche Wertorientierungen und soziales Kapital ("Kontakte") sind wichtig für beruflichen Erfolg. Schlüsselqualifikationen zeigen einen nur geringen Einfluss.Auch unter Akademikern sind Frauen gegenüber Männern beruflich benachteiligt. Der Bericht bereichert die Forschung zum Gender Wage Gap um den Einfluss geschlechtsspezifischer Orientierungen.Vorliegendes Papier ist die Dokumentation eines von der Hans-Böckler Stiftung geförderten Online-Panels. Panelteilnehmer sind Absolventen und Studierende kurz vor ihrem Abschluss. Die Studie verfolgte den Berufseinstieg der Absolventen über zwei Jahre und erfasste deren aktuelle Situation (Suche/Erwerbstätigkeit etc.).

When conducting quantitative surveys, it is crucial to choose a research design that is tailored both to the target group and to the particular context. According to the literature, personalized salutations in survey invitations have a beneficial effect on response rate and consequently on data quality. However, in our case, the 2019/20 cohort of the DZHW Scientist Survey, it remained to be determined which personalized salutation is most suitable to the specific target group of scientists in Germany and whether there are differences according to subgroups such as academic status or gender. We argue that for many survey studies this question of specific tailoring for a target population arises. Also, because personalization necessitates a significantly increased effort for the collection and preparation of address data, it can be decisive to know whether or not there is an advantage over simple non-personalized forms of address. In the case of scientists in Germany we tested three different personalized forms of address at the beginning of the field phase with 20.000 invitees. Each of the three is associated with different social signals and requirements for address data, and compared with the benchmark of the non-personalized, but ingroup signalling salutation “Dear Colleague”. We find that, for all three status groups - professors, postdocs, and predocs - personalized salutations are associated with significantly higher response rates. However, the exact preferences for one form of personalization or another vary between these subgroups. The results from the experiment allowed us to precisely tailor salutations to subgroups for the remainder of the field phase, and to maximize the final overall response in the survey.
Working conditions in the science system have long been complained about as insecure and lacking in perspective. It is an open question who could benefit from more secure employment. While a widespread rhetoric in political debates and some economic approaches suspect that greater job security undermines scientist’s motivation, efforts and performance, psychological approaches on work and motivation see increasing satisfaction on the part of scientists as a driver for the development of higher performance potential. We are investigating the relationship between contract situation, satisfaction and performance in science on the basis of a representative sample of 4,134 postdocs from all universities in Germany. The results show positive effects of secure employment on both satisfaction and output. However, the output effect is only partly mediated by satisfaction. In contrast to earlier studies, relevant contextual characteristics of the work situation are controlled for, so that the effect of the secure employment is more clearly carved out. The study refutes negative attributions of permanent positions on work results and thus the hammock argument. Thus, all parties may benefit from stable jobs for researchers.

Soziologische Handlungstheorien stoßen an eine Grenze, wenn sie für die Erklärung sozialer Varianz nur die bewussten Wahrnehmungen und expliziten Situationsinterpretationen von Individuen heranziehen und präreflexive und implizite Wahrnehmungsprozesse und Sinnstiftungen ausschließen. Sie können dann nicht die feinen Unterschiede erklären, die sich im Geschmack, im Gefühl für die Situation oder in kulturellen Praktiken der alltäglichen Lebensführung offenbaren. Mit der Affektsteuerungstheorie liegt eine Theorie vor, die implizite Wahrnehmungen in Form affektiver Bedeutungen zur Grundlage individueller Handlungserklärungen macht und damit geeignet ist, soziokulturelle Varianz im Handeln auch auf dieser Ebene zu erklären. Allerdings haben sich bisherige Studien zu affektiven Bedeutungen überwiegend auf internationale Kulturvergleiche beschränkt und affektive Bedeutungen für ganze Sprachgemeinschaften und Nationen untersucht, sich aber nicht systematisch für innergesellschaftliche soziokulturelle Gruppen wie Schichten und Milieus interessiert. Die Arbeit schließt diese Forschungslücke und untersucht, inwiefern sich in affektiven Bedeutungen auch innergesellschaftliche kulturelle und soziale Differenzen spiegeln. Dafür wird das Konzept der affektiven Bedeutungen zunächst in einen kulturtheoretischen Rahmen eingeordnet, der soziale Varianz im Handeln mit den Wahrnehmungen der Akteure erklärt. Es wird dafür argumentiert, Prozesse affektiver Wahrnehmungen als einen kulturellen Mechanismus zu betrachten, der zwischen sozialer Struktur und individuellem Handeln vermittelt und so soziale Varianz im individuellen Handeln zu erklären vermag. Affektive Bedeutungen erweisen sich dabei als Bestandteile verkörperter Kultur, die in Form impliziter assoziativer Bedeutungen durch Situationswahrnehmungen und -interpretationen handlungswirksam werden. Drei empirische Studien liefern grundlegende Befunde für eine soziokulturelle Stratifizierung affektiver Bedeutungen und unterstützen damit die These, dass affektive Wahrnehmung ein kultureller Mechanismus zur Generierung interindividueller Varianz im sozialen Handeln darstellt. Die erste Studie weist anhand eines soziale stratifizierten bundesweiten Samples mit 2849 Befragten zunächst nach, dass affektive Bedeutungen in den drei Kerndimensionen Evaluation. Potency und Activity in hohem Maß gesellschaftlich geteilt werden. Vor dem Hintergrund der geteilten Bedeutungen zeigen sich jedoch schichtspezifische Unterschiede, die eine soziale Stratifizierung der affektiven Bedeutungen demonstrieren. Eine weitere Studie eruiert systematische Unterschiede in den affektiven Bedeutungen zwischen verschieden Lebensführungstypen. Die soziale Lage dieser Lebensführungstypen spiegelt sich sowohl in ihrem Selbstbild als auch in ihrem Weltbild, d.i. die affektiven Bedeutungen relevanter sozialer Konzepte und Identitäten. Eine dritte Studie liefert Befunde für die Handlungswirksamkeit affektiver Wahrnehmungen und damit verbundener Identifikationsprozesse. Am Beispiel der Parteiidentifikation wird gezeigt, dass über affektive Bedeutungen gemessene Parteiidentifikationen die spätere Wahlentscheidung in hohem Maß bestimmen. Darüber hinaus zeigt diese Studie, dass Parteiidentifikationen eng mit dahinterstehenden politischen Weltbildern verbunden sind, die sich ebenfalls über affektive Bedeutungen messen lassen. Insgesamt zeigt sich, dass affektive Wahrnehmung als ein kultureller Mechanismus individueller und situationsbezogener Handlungserklärung verstanden werden kann. Affektive Bedeutungen sind ein geeigneter Zugang zu solchen Wahrnehmungen, da sie sich als sozial und kulturell strukturiert erweisen und die soziale Lage sowie die damit verbundenen differenzierten Erfahrungshintergründe der Individuen spiegeln. Die Arbeit macht einen konzeptuellen Vorschlag, wie affektive Bedeutungen vor dem Hintergrund sozialer Ungleichheit in einer modernen kulturtheoretischen Handlungserklärung zu verorten sind. Empirisch erweitert sie die bisherige Forschung zu affektiven Bedeutungen zum einen durch sozial stratifizierte affektive Wörterbücher und eine methodische Perspektive, wie innergesellschaftliche Differenzen in den affektiven Wahrnehmungen systematisch zu untersuchen sind.
