Welfare is the largest expenditure category in all advanced democracies. Consequently, much literature has studied partisan effects on total and policy-specific welfare expenditure. Yet, these results cannot be trusted: The methodological standard is to apply time-series cross-section-regressions to annual observation data. But governments hardly change annually. Thus, the number of observations is artificially inflated, leading to incorrect estimates. While this problem has recently been acknowledged, it has not been convincingly resolved. We propose Mixed-Effects Models as a solution, which allow decomposing variance into different levels and permit complex cross-classification data structures. We argue that Mixed-Effects models combine the strengths of existing methodological approaches while alleviating their weaknesses. Empirically, we study partisan effects on total and on disaggregated expenditure in 23 OECD-countries, 1960-2012, using several measures of party preferences.

We cannot imagine a political system without opposition. Despite this crucial position in politics, political science has largely neglected to study oppositions. Attempting to fill this gap, this article analyses the institutional opportunities of parliamentary oppositions. It offers a parsimonious framework by distinguishing two dimensions of opposition influence: Some institutions enable oppositions to control governments, while others offer opportunities to present alternatives. A comparison of oppositions’ opportunities in 21 democracies shows that countries fall into four groups along these dimensions: In majoritarian democracies, weak control mechanisms are countered by excellent opportunities to publicize alternatives. Consociational democracies are characterized by strong control mechanisms, but provide only weak opportunities to present alternatives. Moreover, in Southern Europe, control mechanisms and opportunities to present alternatives are weak, while both are pronounced in Nordic Europe. The results are summarized in three indices that can easily be applied in future research examining oppositions and their power.

Cryopreservation attracts attention as a practice grounded in high expectations: current life is suspended for future use—to generate life, to save life, and to resurrect life. But what happens when high expectations in cryobanking give way to looming uselessness and the risk of failure? Based on ethnographic insights into the case of umbilical cord blood (CB) banking in Germany, this contribution investigates the liminal state of “non-failure.” Averting failure amid a lack of success in this field requires putting effort into the construction of value. The resulting practices and dynamics overflow generic stories of commercialization and instrumentalization of biological material and are best grasped as an expanded version of the recently coined notion of “cryovalue.” The long-term availability of cryopreserved CB facilitates the steady yield of social and economic capital beyond and after promise. Moreover, the value construction is reoriented from CB itself toward the socio-technical cryo-arrangements in which it is embedded. In exemplifying how it expands the understanding of the diversity of valuation and valorization practices, continuities, and economic endurance in cryoeconomies and bioeconomies, the paper advocates the study of their ambivalent and allegedly uneventful sites.

Studies of occupational sex segregation rely on the sociocultural model to explain why some occupations are numerically dominated by women and others by men. This model argues that occupational sex segregation is driven by norms about gender-appropriate work, which are frequently conceptualized as gender-typed skills: work-related tasks, abilities, and knowledge domains that society views as either feminine or masculine. The sociocultural model thus explains the primary patterns of occupational sex segregation, which conform to these norms: Requirements for feminine (masculine) skills increase with women’s (men’s) representation in the occupation. However, the model does not adequately explain cases of segregation that deviate from these norms or investigate the ways in which feminine and masculine skills co-occur in occupations. The present study fills these gaps by evaluating two previously untested explanations for deviations from the sociocultural model. The findings show that requirements for physical strength (a masculine skill) increase with women’s representation in professional occupations because physical strength skills co-occur with substantially higher requirements for feminine skills that involve helping and caring for others. These results indicate that the sociocultural model, and more generally explanations for how gender norms drive occupational sex segregation, can be improved by examining patterns of gender-typed skill co-occurrence.

The commulative thesis investigates the relationship between perceived loneliness and political participation. the results of four published papers indicate that loneliness causes distrust and sense of alienation, which leads to political demobilization as well as polarization.
