Unequal policy responsiveness in the Netherlands

Scholars have long recognized that equality in policy responsiveness is potentially undermined by the existence of economic inequality. However, there is still a lack of empirical research testing whether and how this actually occurs, especially outside of the USA. This study takes up the question whether unequal representation also exists in a country that is in some ways a least-likely case, namely the Netherlands. It does so by linking public opinion to policy on 291 potential policy changes between 1979 and 2012. This reveals, first, that policy responsiveness is much stronger for high incomes than for low or median incomes. Second, an exploration of the underlying causal mechanisms finds support for the role of political participation of wealthier versus poorer citizens, while the socioeconomic background of parliamentarians relative to the broader public does not seem to matter. Corporate lobbying may also contribute to unequal responsiveness.NWO406-15-089Institutions, Decisions and Collective Behaviou

Can verbal suggestions strengthen the effects of a relaxation intervention?

Short stress management interventions such as relaxation therapy have demonstrated preliminary effectiveness in reducing stress-related problems. A promising tool to strengthen the effectiveness of relaxation-based interventions is the use of verbal suggestions, as previous research provided evidence that verbal suggestions can induce positive outcome expectancies, facilitate adaptive responses to stress and improve health outcomes. The present experimental proof-of-concept study aimed to investigate the effects of a brief relaxation intervention and specifically the role of verbal suggestions on stress-related outcomes assessed by self-report questionnaires and psychophysiological data. 120 participants (mean age = 22.1 years) were randomized to one of four intervention conditions: a brief relaxation intervention plus verbal suggestions condition, a brief relaxation intervention only condition, a verbal suggestions only condition, and a control condition. Afterwards, participants were subjected to a psychosocial stress challenge to assess reactivity to a stressful event. Immediately after both relaxation interventions (with and without verbal suggestions), lower self-reported state anxiety was found compared to the control condition, but no differences were observed in response to the stressor. The verbal suggestions only condition did not impact state anxiety. No significant effects were found for verbal suggestion interventions on cortisol, alpha amylase, heart rate and skin conductance. This is the first study investigating the role of verbal suggestions in the effectiveness of a brief relaxation intervention. Although this experimental proof-of-concept study provides support for the effectiveness of a brief relaxation intervention in lowering state anxiety directly after the intervention, the effects did not impact the response to a subsequent stressor and we did not observe any evidence for the add-on effectiveness of verbal suggestions. The effectiveness of brief relaxation interventions on stress responses should be investigated further in future research by incorporating interventions that are tailored to the specific stress challenge and various types of verbal suggestions

Degrees of influence: educational inequality in policy representation

Education plays an important role in the political, social and economic divisions that have recently characterised Western Europe. Despite the many analyses of education and its political consequences, however, previous research has not investigated whether government policy caters more to the preferences of the higher educated than to the preferences of the lower educated. We address this question using an original dataset of public opinion and government policy in the Netherlands. This data reveals that policy representation is starkly unequal. The association between support for policy change and actual change is much stronger for highly educated citizens than for low and middle educated citizens, and only the highly educated appear to have any independent influence on policy. This inequality extends to the economic and cultural dimensions of political competition. Our findings have major implications for the educational divide in Western Europe, as they reflect both a consequence and cause of this divide.NWO406‐15‐089Institutions, Decisions and Collective Behaviou

Superconductor-insulator transition driven by local dephasing

We consider a system where localized bound electron pairs form an array of "Andreev"-like scattering centers and are coupled to a fermionic subsystem of uncorrelated electrons. By means of a path-integral approach, which describes the bound electron pairs within a coherent pseudospin representation, we derive and analyze the effective action for the collective phase modes which arise from the coupling between the two subsystems once the fermionic degrees of freedom are integrated out. This effective action has features of a quantum phase model in the presence of a Berry phase term and exhibits a coupling to a field which describes at the same time the fluctuations of density of the bound pairs and those of the amplitude of the fermion pairs. Due to the competition between the local and the hopping induced non-local phase dynamics it is possible, by tuning the exchange coupling or the density of the bound pairs, to trigger a transition from a phase ordered superconducting to a phase disordered insulating state. We discuss the different mechanisms which control this occurrence and the eventual destruction of phase coherence both in the weak and strong coupling limit.Comment: 16 pages, 5 figures, submitted to PRB (05-Feb04
