An important empirical literature evaluates whether voters are rational by examining how electoral outcomes respond to events outside the control of politicians, such as natural disasters or economic shocks. The argument is that rational voters should not base electoral decisions on such events, so evidence that these events affect electoral outcomes is evidence of voter irrationality. We show that such events can affect electoral outcomes, even if voters are rational and have instrumental preferences. The reason is that these events change voters' opportunities to learn new information about incumbents. Thus, identifying voter (ir)rationality requires more than just identifying the impact of exogenous shocks on electoral fortunes. Our analysis highlights systematic ways in which electoral fortunes are expected to change in response to events outside incumbents' control. Such results can inform empirical work attempting to identify voter (ir)rationality.  相似文献

Due to the lack of family drug treatment courts, families are often torn apart when a parent has a substance abuse problem. Children of substance abusers are often abused and neglected. However, children in these tough living situations fear seeking help because they do not want to be the reason that their family is torn apart and they are placed in the foster care system. This Note proposes a federal statute that requires all states to implement family drug treatment courts. These courts allow families to stay intact while providing the parent with the help that he or she needs.  相似文献

The Mozambique Eyecare Project was an international partnership to implement and research eye health education in Mozambique and the Africa region. An optometry degree was developed at Universidade Lúrio, Mozambique. In addition, existing eye health workers were upskilled with training. Researchers from various disciplines evaluated the project and its potential for impact on eye health in the region. The body of evidence generated from the research provides useful lessons for development programmes in general, as well as specific lessons for delivering eye health education and service delivery models for low-income settings.  相似文献

The public administration literature once devoted great effort to identify the determinants of administrative intensity in organizations. While this literature has received some renewed attention, there remain questions about what aspects of organizational environments generate growth in administrative intensity, particularly as related to political oversight and external accountability mechanisms. This article aims to expand current theory on the determinants of administrative personnel and costs using data on four‐year public universities in the United States from 1998 to 2011, as this setting has received considerable criticism for perceived administrative bloat. Findings suggest that which political party is in control substantially influences both administrative costs and total personnel. These administrative levels, in turn, have a curvilinear relationship with student outcomes.  相似文献

Abstract

Across multiple African countries, discrepancies between administrative data and independent household surveys suggest official statistics systematically exaggerate development progress. We provide evidence for two distinct explanations of these discrepancies. First, governments misreport to foreign donors, as in the case of a results-based aid programme rewarding reported vaccination rates. Second, national governments are themselves misled by frontline service providers, as in the case of primary education, where official enrolment numbers diverged from survey estimates after funding shifted from user fees to per pupil government grants. Both syndromes highlight the need for incentive compatibility between data systems and funding rules.  相似文献

Runaway and homeless youth often have a constellation of background behavioral, emotional, and familial problems that contribute to stress and maladaptive behaviors, which, in turn, can lead to self-harming and suicidal behaviors. The current study examined the roles of stress and maladaptive behaviors as mediators between demographic and psychosocial background characteristics and self-injurious outcomes through the lens of the stress process paradigm. The model was tested in a sample of runaway and homeless youth from Los Angeles County (N = 474, age 12–24, 41 % female, 17 % White, 32.5 % African American, 21.5 % Hispanic/Latino). Background variables (gender, age, sexual minority status, parental drug use history, and emotional distress) predicted hypothesized mediators of maladaptive behaviors and recent stress. In turn, it was hypothesized that the mediators would predict self-harming behaviors and suicide attempts in the last 3 months. Females and LGBT (lesbian, gay, bisexual, transgender) youth were more likely to have self-harmed and attempted suicide; younger participants reported more self-harming. The mediating constructs were associated more highly with self-harming than suicide attempts bivariately, although differences were modest. Maladaptive behaviors and recent stress were significant predictors of self-harm, whereas only recent stress was a significant predictor of suicide attempts. All background factors were significant predictors of recent stress. Older age, a history of parental drug use, and greater emotional distress predicted problem drug use. Males, younger participants, and participants with emotional distress reported more delinquent behaviors. Significant indirect effects on self-harming behaviors were mediated through stress and maladaptive behaviors. The hypothesized paradigm was useful in explaining the associations among background factors and self-injurious outcomes and the influence of mediating factors on these associations.  相似文献

Protective and risk factors associated with rates of early sexual debut and risky sexual behaviors for a sample of low-income adolescent boys were examined using bioecological theory framed by a resiliency perspective. Protective processes examined include a close mother–son and father–son relationship, parental monitoring and family routines, as well as the adolescent boy’s academic achievement, expectations, and school recognition. The risk factors assessed were delinquent behaviors, if the adolescent was born to a teenage mother, family structure, monthly family income, risky neighborhood environments, family of origin welfare receipt, and maternal education. Waves one (1999) and two (2001) of Welfare, Children, and Families: A Three-City Study were used (N = 528; Wave 1 ages 10–14 years). Associations between early sexual debut and risky sexual behaviors with individual, family, school, and neighborhood protective and risk factors were addressed through a series of d-probit and Ordinary Least Squares multiple regression techniques. When protective and risk factors were addressed independently, academic achievement and parental monitoring protected adolescent boys from early sexual debut and risky sexual behaviors while drug and alcohol use and school problems placed them at risk for these behaviors. However, when the model is assessed together, early parental monitoring and academic achievement were shown to protect boys’ early sexual debut and risky sexual behaviors by reducing their delinquent behaviors, specifically early drug and alcohol use and school problems.

Using a sample of 7,881 African American (915 males and 1,073 females) and White (2,864 males and 3,029 females) adolescents from Waves 1 and 3 of the National Longitudinal Study of Adolescent Health, this study examined the psychosocial consequences that obese adolescents encounter as they reach young adulthood. Results indicate that obesity among adolescent females is associated with a lower status attainment in young adulthood than normal weight adolescent females. In addition, obese adolescent females have more depressive symptoms in young adulthood than normal weight females, even after controlling for prior depressive symptoms in adolescence. Obesity status among adolescent males is not associated with poorer psychosocial outcomes in young adulthood. We did not find evidence of an interaction between obesity status and race, indicating no significant differences in psychosocial outcomes for obese White compared to obese African American adolescents.
