Coumarin, a simple, commodity chemical isolated from beans in 1820, has, to date, only yielded one solid state structure. Here, we report a rich polymorphism of coumarin grown from the melt. Four new metastable forms were identified and their crystal structures were solved using a combination of computational crystal structure prediction algorithms and X-ray powder diffraction. With five crystal structures, coumarin has become one of the few rigid molecules showing extensive polymorphism at ambient conditions. We demonstrate the crucial role of advanced electronic structure calculations including many-body dispersion effects for accurate ranking of the stability of coumarin polymorphs and the need to account for anharmonic vibrational contributions to their free energy. As such, coumarin is a model system for studying weak intermolecular interactions, crystallization mechanisms, and kinetic effects. [less ▲]

Background: Sleep problems are common among university students. Poor sleep is associated with impaired daily functioning, increased risk of psychiatric symptoms, and somatic complaints such as pain. Previous results suggest that poor sleep exacerbates pain, which in turn negatively affects sleep. The purpose of the present study was to determine prevalence rates, comorbidity, and role of depression as a factor of moderating the relationship between sleep and physical complaints in German university students. Samples and methods: In total, 2443 German university students (65% women) completed a web survey. Self-report measures included the Pittsburg Sleep Quality Index, three modules of the Patient Health Questionnaire, and a questionnaire on the functional somatic syndromes (FSSs). Results: More than one-third (36.9%) reported poor sleep as assessed by the Pittsburgh Sleep Quality Index. Somatoform syndrome was identified in 23.5%, and the prevalence of any FSS was 12.8%. Self-reported sleep quality, sleep onset latency, sleep disturbances, use of sleep medications, and daytime dysfunctioning were significant predictors of somatoform syndrome, whereas sleep efficiency and sleep duration influenced somatic complaints indirectly. Moderate correlations were found between stress, anxiety, somatoform syndrome, depression, and overall sleep quality. The effect of somatic complaints on sleep quality was associated with the severity of depression. Anxiety shows direct effects on somatization and depression but only indirect associations with sleep quality. [less ▲]

Children and their parents have become a focal point of debates on ‘new social risks’ and the strong need for ‘new public policies’ in many European welfare states. Policy-related elites, along with UNICEF, the OECD, and the EU, have converged in defining such risks. They outlined parenting support measures, rules, and procedures to better safeguard children and to activate their potential, promote their well-being, and ensure equal opportunities. Parents are expected to offer their children ‘grade A’ parenting. However, they are increasingly suspected of failing to meet public expectations. Hence, agencies advocating children’s best interest are intervening in parenting practices at an increasingly earlier age on the grounds of potential risks. The boundaries between what has been seen as ‘family’ or ‘private’ versus ‘public affairs’ are being redrawn by discourses as well as by ‘evidence-based’ measures to intervene and tackle child-related risks. Contributors to this special issue from Belgium, England, France, Germany, the Netherlands, and Sweden are scrutinizing this ‘turn to parenting’. They analyse which parenting practices are now ‘in the spotlight’ and report on recent forms of support for parents. Whereas debates on ‘new risks’ and the need for ‘child-centred social investments’ have converged, parenting support measures still vary across countries both quantitatively and qualitatively. Such variations result from path-dependent institutional settings, public sentiments, and policy ‘cultures’. This issue offers an excellent opportunity to study parenting support policies in countries representing different ‘worlds’ of family policy. It highlights different ideas on the child’s proper status in society and on good parenting along with variations in the influence of experts on parenting and practitioners’ attitudes towards it – especially the parenting practiced by mothers from different backgrounds.

In the last decade, the issue of online deliberation (or web-deliberation) has gained an important visibility among the scholars in the domain of political science, political philosophy, political communication as well as software designers. It corresponds not only to a topic of analysis – that can be broadly defined as the quantitative and qualitative assessment of the political and public debates online - but also to a democratic model of e-democracy, that aims to shape the different political usage of the web according to the deliberative values. A pertinent way to analyze this broad phenomenon is to subdivide its analysis in three sections which content is partly based on updated findings of my book Promises and Limits of web-deliberation. The first section refers to the deliberative theory on which the empirical research is based. The second section deals with the complex issue of operationalizing the deliberative theory. The last section provides an overview of the online deliberative empirical studies that were conducted this last decade by distinguishing three broad research fields: i) The studies that aim at measuring the usage of the political web-debates and the characteristics of the users; ii) The studies that identify and compare the social and political actors that offer possibilities of online debates; iii) The studies assessing the quality of deliberation in different discursive online settings and the ones aiming at defining the factors that could explain variations in web-deliberation.

Disciplinary and regulatory governmental proceedings intersect, for instance when disciplinary rules and judiciary norms operate on the basis of suspicion and there-fore just happen to disenfranchise certain groups of people. The case study of Luxembourg’s practice of expulsion before the Second World War offers insights into the administration of ‘undesirable foreigners’ which was based on identifying women who supposedly infringed bourgeois moral gender order. Women from abroad of dubious reputation could become a double threat to bourgeois norms and values. Based on extensive research on archival funds, this article seeks to shed light on the intersecting quality of gendering foreigners and ethnicizing prostitutes in a self-reinforcing bureaucratic procedure leading to deportation.
