Previous research dismisses the possibility that populist, male-dominated parties could positively affect gender equality. Yet, evidence from Eastern Europe points at the opposite: Center-rightist formations, led by notable men, have effectively nominated women to office. What can explain such a puzzling phenomenon? This study argues that i) the centralized structure and practices in these populist parties make it possible to avoid the reluctance of gatekeepers to let female candidates run; and that ii) regardless of ideological or cultural predispositions, supporters loyally approve the nomination decisions made by their charismatic leader. We analyze data on three populist parties in Bulgaria and Poland. Our findings confirm that these formations elected more women than the leftist parties because of strategies to nominate female candidates higher on the list. Voters were also more likely to favor female candidates in the open-list system in Poland.

Polymeric surfaces suitable for cell culture (DR/Pec) were constructed from diazoresin (DR) and pectin (Pec) in a form of ultrathin films using the layer-by-layer (LbL) technique. The surfaces were functionalized with insulin using diazonium chemistry. Such functionalized surfaces were used to culture human mesenchymal stem cells (hMSCs) to assess their suitability for bone tissue engineering and regeneration. The activity of insulin immobilized on the surfaces (DR/Pec/Ins) was compared to that of insulin dissolved in the culture medium. Human MSC grown on insulin-immobilized DR/Pec surfaces displayed increased proliferation and higher osteogenic activity. The latter was determined by means of alkaline phosphatase (ALP) activity, which increases at early stages of osteoblasts differentiation. Insulin dissolved in the culture medium did not stimulate cell proliferation and its osteogenic activity was significantly lower. Addition of recombinant human bone morphogenetic protein 2 (rhBMP-2) to the culture medium further increased ALP activity in hMSCs indicating additive osteogenic action of immobilized insulin and rhBMP-2.

Though the concept of choice is essential to democracy, little is known about how citizens make sense of the diversity of policies offered by political elites. Research has found that institutional arrangements such as low electoral thresholds and multiple party competitors are associated with greater policy choice. Other work emphasises non‐institutional factors. No research, however, examines what the voters think. In this article these alternative explanations are assessed in terms of whether citizens believe parties to provide choice over policy. Evidence from 25 democracies reveals that electoral and party systems have no direct effect. Choice perceptions are instead affected by non‐policy factors: social heterogeneity and individual political dispositions. This result contrasts with analyses showing a strong connection between electoral rules and the diversity of messages communicated by parties during campaigns. The article also shows how choice perceptions matter for political behaviour. Overall, study findings imply that the promise of institutions for fostering representation is weaker than previously assumed.
