The right-wing PVV and the left-wing SP are seen as populist parties who are fierce ideological adversaries in the Dutch political spectrum. We study the similarities and differences in municipal contexts that explain their electoral success. Results of the 2010 national elections at the municipality level are analyzed for nearly all (N=403) Dutch municipalities. Hypotheses are formulated based on integrated group threat theory and relative deprivation theory. Results indicate similarities but also clear differences in the contexts in which SP and PVV thrive. PVV is more successful in municipalities with more immigrants and a higher average perception of unsafety, SP thrives more under local socioeconomic deprivation.

LAY SUMMARY Initiation rituals have existed in the military for a very long time. The goal of these traditions is generally to introduce (new) military personnel to the organization, to learn about hierarchies, practices, and norms, and to make sure personnel are committed to and identify with the armed forces. However, hazing can also occur. Hazing refers to initiation activities that are abusive and include harassment and humiliation. These activities can cause severe mental and physical harm to the health and well-being of military personnel. Hazing can also negatively affect the functioning and effectiveness of individuals and entire units in times of peace and war. Many military organizations and scholars agree that hazing is dangerous and unethical. However, hazing still exists. This scoping review was conducted to gain more insight into what is known about hazing in the military, why it occurs, and what may be done to prevent it. Findings show that more research is needed, and military organizations may have to rethink their approaches to hazing if they want to prevent it and protect personnel from harm.

Objective: This study assessed the effect of a default nudge to reduce sedentary behaviour at work over time. Design and main outcome measures: A field study was conducted at a governmental organisation. In the present study, the default setting of sit–stand desks (SSDs) was changed from sitting to standing height during a two-week intervention. Stand-up working rates were calculated based on observations that were done prior to, during, two weeks after and two months after the intervention. Additionally, a pre-measure survey (n = 606) and post-measure survey (n = 354) were completed. Intention and social norms concerning stand-up working were compared for the 183 employees who completed both pre- and post-assessments (45.4% female, Mage = 44.21). Results: Stand-up working rates raised from 1.82% in the baseline to 13.13% during the intervention. After the nudge was removed the percentage was 10.01% after two weeks and 7.78% after two months. A multilevel analysis indicated a significant increase in both intention and social norms after the nudge intervention. Conclusions: This study shows that a default nudge can increase stand-up working rates in offices with SSDs at least until two months after the nudge intervention.

A method is presented for long-term monitoring of vital signs tested during physical exercise. The system is based on reflective photoplethysmography (PPG), whose main component is a micro-optoelectronic sensor. The sensor is sealed within a biocompatible otoplastic housing so that it can be placed in the external auditory canal. The electronic device has a Bluetooth connection which enables to record/visualize the PPG signal on a personal computer or SmartPhone. This technology was tested indoors with a subject running on a treadmill at different speeds. The PPG signal was recorded together with an ECG used as a reference, and with an accelerometer to monitor and record motor activity. Theaccelerometer data were later used to reduce motion artifacts in the PPG signal. The results show that the system has potential to monitor cardiac activity at moderate speed (up to 4 km/h), but with increasing speed (i.e. running) the motion artifacts dominate the PPG. Therefore, additional studies on signal processing are needed to actively reduce motion artifacts, including the accelerometer data.

AbstractLittle is known about the conditions under which paternal incarceration is harmful to children and the mechanisms that explain this. This study addressed the family relationship context in the associations between paternal incarceration and adolescents' internalizing and externalizing problem behaviors. Using data from the Future of Families and Child Wellbeing Study, a moderated mediation model was specified where paternal incarceration predicted adolescents' internalizing and externalizing problem behaviors through family relationship quality, and where the mediating role of family relationship quality was moderated by pre-incarceration family relationship characteristics. Using latent profile analyses, three pre-incarceration family clusters were identified ("Cohesive"; "Fragmented"; "Disharmonious"). Analyses indicated that the association between paternal incarceration and family relationship quality differed across pre-incarceration family clusters and that decreased father-mother relationship quality mediated the negative association between paternal incarceration and adolescents' internalizing and externalizing problem behaviors among "Cohesive" and "Fragmented", but not among "Disharmonious" family clusters. The findings suggest that adolescents with more harmonious pre-incarceration family relationships are most vulnerable to the negative consequences of paternal incarceration. The study demonstrates the need to consider the family relationship context to understand the intergenerational consequences of incarceration.
