Agency has received much attention in recent historical institutionalist theorizing of change processes, but remains largely disconnected from questions about mechanisms that stabilize institutions. To help fill this lacuna, the paper presents bricolage as one key mechanism through which actors stabilize an institutional setup. It suggests that institutions may be defended by keeping intact the institutional logic on which the incumbent coalition is based, but rearrange the salience of the ideational and institutional elements that make up the existing institutional setup. The empirical relevance of the argument is supported through a case analysis of a 1980-reform that could have changed the face of German corporatism, but never was, namely the policy of collective equity funds (Tariffonds). Through process tracing, we explain the fate of the reform with the effectiveness of a last-minute intervention based on a bricolage of the extant institutional logic.

Background and aims
Although large-scale population studies have linked the use of classic psychedelics (lysergic acid diethylamide, psilocybin, or mescaline) to reduced odds of physical health problems, mental health problems, and criminal behavior, the roughly 35 million adults in the United States who have used classic psychedelics are nonetheless stigmatized in the American job market. Various federal organizations in the United States automatically reject applicants on the sole basis of prior psychedelic use, thereby practicing an open form of legal discrimination against these applicants. The present study investigates whether this discrimination can be justified based on associations between lifetime classic psychedelic use and motivationally-based workplace absenteeism.

Methods
Using pooled cross-sectional data from the National Survey on Drug Use and Health (2013–2019) on 193,320 employed adults in the United States, this study tests whether lifetime classic psychedelic use predicts the number of workdays employees skipped in the last month (i.e., motivationally-based workplace absenteeism).

Results
After adjusting for sociodemographics, physical health indicators, and other substance use, no significant association between lifetime classic psychedelic use and motivationally-based workplace absenteeism is found.

Conclusion
This study builds on classic psychedelic research that is just beginning to take work-specific outcomes into account and offers empirical justification for the elimination of arbitrary drug-based recruitment policies in the workplace.

Contact restrictions and distancing measures are among the most effective non-pharmaceutical measures to stop the spread of the SARS-CoV2 virus. Yet, research has only begun to understand the wider social consequences of these interventions. This study investigates how individuals' social networks have changed since the outbreak of the pandemic and how this is related to individuals' socio-economic positions and their socio-demographic characteristics. Based on a large quota sample of the German adult population, we investigate the loss and gain of strong and weak social ties during the pandemic. While about one third of respondents reported losing of contact with acquaintances, every fourth person has lost contact to a friend. Forming new social ties occurs less frequently. Only 10-15% report having made new acquaintances (15%) or friends (10%) during the pandemic. Overall, more than half of our respondents did not report any change, however. Changes in social networks are linked to both socio-demographic and socio-economic characteristics, such as age, gender, education, and migration background, providing key insights into a yet underexplored dimension of pandemic-related social inequality.

Research on differentiated integration (DI) in the European Union has burgeoned in recent years. However, we still know little about citizens’ attitudes towards the phenomenon. In this article, we argue that at the level of individual citizens, liberal economic values increase support for DI. Stronger preferences for equality, in contrast, make opposition to the concept more likely. Similarly, concerns about discriminatory differentiation at the member state level lead citizens to oppose DI. We test the theoretical claims by analysing survey data on citizens’ attitudes towards a ‘multi-speed Europe’. Supporters of DI, indeed, are marked by liberal economic attitudes. In contrast to general EU support, we do not find robust correlations with socio-demographic variables. Moreover, the data reveal striking differences amongst macro-regions: support for DI has become much lower in Southern European states. We attribute this opposition to negative repercussions of the Eurozone crisis.

In Germany, studies have shown that official coronavirus disease 2019 (COVID-19) vaccination coverage estimated using data collected directly from vaccination centers, hospitals, and physicians is lower than that calculated using surveys of the general population. Public debate has since centered on whether the official statistics are failing to capture the actual vaccination coverage. The authors argue that the topic of one’s COVID-19 vaccination status is sensitive in times of a pandemic and that estimates based on surveys are biased by social desirability. The authors investigate this conjecture using an experimental method called the item count technique, which provides respondents with the opportunity to answer in an anonymous setting. Estimates obtained using the item count technique are compared with those obtained using the conventional method of asking directly. Results show that social desirability bias leads some unvaccinated individuals to claim they are vaccinated. Conventional survey studies thus likely overestimate vaccination coverage because of misreporting by survey respondents.

Despite questions having a long-standing history in theoretical linguistics, the interface between empirically grounded corpus linguistics of questioning behaviour and analytically driven pragmatic theory of question structure and context has received significantly less attention. This paper aims to contribute to this field of research by showing that a four-way categorisation into question types, namely, pure questioning, assertive questioning, rhetorical questioning and challenge questioning, allows us to capture and represent questions in over two million words in natural language argumentative dialogue. In this type of dialogue questioning has been claimed to serve as the engine that drives the shape and development of a discourse. Our investigation covers three genres of argumentative discourse in which questions play a key role, namely political debates, moral dilemmas and sessions of participatory deliberative democracy. Through deep algorithmic analysis of the data, we test a variety of hypotheses from argumentation and linguistic theory, clearly demonstrating for the first time that (particular types of) questions directly catalyse argument structure and that the illocutionary consequences of non-canonical questions are much more varied than previously thought.
