Child Health in Elementary School Following California's Paid Family Leave Program

We evaluate changes in elementary school children health outcomes following the introduction of California's Paid Family Leave (PFL) program, which provided parents with paid time off following the birth of a child. Our health outcomes—overweight, ADHD, and hearing‐related problems—are characterized by diagnosis rates that only pick up during early elementary school. Moreover, our health outcomes have been found to be negatively linked with many potential implications of extended maternity leave—increased breastfeeding, prompt medical checkups at infancy, reduced prenatal stress, and reduced non‐parental care during infancy. Using the Early Childhood Longitudinal Studies (ECLS) within a difference‐in‐differences framework, our results suggest improvements in health outcomes among California elementary school children following PFL's introduction. Furthermore, the improvements are driven by children from less advantaged backgrounds, which is consistent with the notion that California's PFL had the greatest effect on leave‐taking duration after childbirth mostly for less advantaged mothers who previously could not afford to take unpaid leave.     

Security Providers: Obstacles to Effectiveness in Democracies

To usefully discuss security, one must analyze the security providers states utilize to enhance international and domestic security. These are the armed forces, police, and intelligence agencies. This paper analyzes the implications of democratization on the requirements—posited as strategies, resources, and coordination institutions—these providers require in order to achieve the goals civilian leaders set for them. In analyzing case studies of how nations implement six different tasks, it becomes clear that the absence, or weakness, in any of the requirements leads to serious weakness in implementation. Two findings from the case studies are particularly important for policy. First, presidents, who are elected directly and for fixed terms, may ignore or even abolish institutions, including national security councils, that are created to coordinate policy. Second, as civilians are in control, if they lack clear incentives they are not willing to provide the necessary requirements for the security providers.     

Centers of Gravity: Regional Powers,Democracy, and Trade

Classic studies on hegemonic stability and power transition suggest that concentration of capabilities favoring a single state can promote economic cooperation and discourage militarized conflict. However, tests of these arguments have been primarily limited to examining temporal variation in global capability distributions and corresponding levels of system-wide cooperation; few have examined the impact of capability concentration at the region level. In this article, we contend that concentration of regional military capabilities corresponds to lower trade costs for states throughout a region and to an incentive for weaker states to de-prioritize expenditure on the military, freeing resources that can be used to promote trade. As a result, this condition promotes higher levels of trade, particularly within the region. We also argue that democratic regional powers are better able to foster confidence in the sustainability of cooperation; thus, the trade-enhancing impact of concentrated regional capabilities is stronger when the predominant state is more democratic. We find evidence in support of our expectations in statistical models examining state trade between 1960 and 2007.     

What encourages households to adopt rice as a new crop? Understanding gender roles and perceptions in households in northern Namibia

This article investigates how the introduction of new crops influences intra-household decision-making among the Ovambo in northern Namibia where women are responsible for crop farming, while men are engaged in livestock farming. It examines gender relations that underlie daily activities. The findings of the study show that women try new crops on their own or with the help of their children and do not negotiate with their husband, mothers, or brothers over household resources such as land, labour, and the cash of other family members. Women avoid conflicts with family members, but may have an increased perception of contribution to the household if they succeed in introducing new crops.     

The evaluation of five electrophoretic phenotyping systems for routine screening of bloodstains

The performance of the polymorphic marker systems group-specific component (GC), phosphoglucomutase-1 (PGM), alpha-2-HS-glycoprotein (A2HS), haptoglobin (Hp), and erythrocyte acid phosphatase (EAP) was evaluated on control bloodstains. The major factors considered were: sensitivity of the test system; stability of the marker; laboratory economics of each test; and distinguishing power (Dp) of the system. GC was considered to be the most suitable marker for routine screening because of its high stability and Dp, and the sensitivity of the immunoblotting detection method. PGM and A2HS were the next most valuable markers followed by Hp. EAP could only be considered useful when large amounts of relatively fresh bloodstain were available.     

The Development of Future Orientation is Associated with Faster Decline in Hopelessness during Adolescence

Hopelessness is implicated in multiple psychological disorders. Little is known, however, about the trajectory of hopelessness during adolescence or how emergent future orientation may influence its trajectory. Parallel process latent growth curve modelling tested whether (i) trajectories of future orientation and hopelessness and (ii) within-individual change in future orientation and hopelessness were related. The study was comprised of 472 adolescents [52% female, 47% Caucasian, 47% received free lunch] recruited at ages 12–13 who completed measures of future orientation and hopelessness at five annual assessments. The results indicate that a general decline in hopelessness across adolescence occurs quicker for those experiencing faster development of future orientation, when controlling for age, sex, low socio-economic status in addition to stressful life events in childhood and adolescence. Stressful childhood life events were associated with worse future orientation at baseline and negative life events experienced during adolescence were associated with both an increase in the trajectory of hopelessness as well as a decrease in the trajectory of future orientation. This study provides compelling evidence that the development of future orientation during adolescence is associated with a faster decline in hopelessness.     

Intra-Campaign Changes in Voting Preferences: The Impact of Media and Party Communication

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.
