Many have questioned whether voters are able to hold incumbent officials electorally accountable through a retrospective voting strategy. We examine U.S. Senate elections from 1962 to 1990 in forty-one states, explaining which incumbents ran for reelection and their success in seeking reelection. We find that an incumbent's deviation from her state party platform decreases the probability that she will run for reelection and win if she runs. Furthermore, the electoral mechanism is found to be more efficient when voters are better informed. Finally, we find that our divergent party platform model provides a better fit than the median voter model. 相似文献

The effects of maternal expressiveness and children's gender on children's nonverbal expressiveness were assessed in two settings. In the laboratory, 30 boys and 30 girls of kindergarten age were unobtrusively videotaped while talking about happy, sad, and fearful experiences and while experiencing three social situations designed to elicit happy, disappointed, and apprehensive feelings. Videotapes were rated for emotion expression, using global ratings and EMFACS codes. In school, teachers rated these children's expression of four discrete emotions. In both the laboratory and school settings children were more positively expressive than negatively so, and positive and negative expressiveness were unrelated. In the laboratory children's positive expressiveness was consistent across the three social situations, but negative expressiveness varied across affective context. In both settings, children of low-expressive mothers were more positively expressive than children of high-expressive mothers, who tended to be more negatively expressive than children of low-expressive mothers. The difference in negative expression appeared most striking for anger. Gender was not predictive of children's expressiveness in either setting 相似文献

Much of the extensive empirical literature on insurance markets has focused on whether adverse selection can be detected. Once detected, however, there has been little attempt to quantify its welfare cost or to assess whether and what potential government interventions may reduce these costs. To do so, we develop a model of annuity contract choice and estimate it using data from the U.K. annuity market. The model allows for private information about mortality risk as well as heterogeneity in preferences over different contract options. We focus on the choice of length of guarantee among individuals who are required to buy annuities. The results suggest that asymmetric information along the guarantee margin reduces welfare relative to a first‐best symmetric information benchmark by about £127 million per year or about 2 percent of annuitized wealth. We also find that by requiring that individuals choose the longest guarantee period allowed, mandates could achieve the first‐best allocation. However, we estimate that other mandated guarantee lengths would have detrimental effects on welfare. Since determining the optimal mandate is empirically difficult, our findings suggest that achieving welfare gains through mandatory social insurance may be harder in practice than simple theory may suggest. 相似文献

This study examines the attribution of responsibility for the problematic response to Hurricane Katrina in the fall of 2005.
Based on social identity theory, the study compared the attribution with racism and non-racism factors (situational vs. dispositional
attributions) between African American and European American students (n = 505). As hypothesized, African American identity was related to greater racism attribution, even after controlling for
demographics, faith factors, and cognitive-emotional reactions to the hurricanes. European American identity was associated
with more executive-responsibility attributions, but the effect vanished after adjusting other factors. The study underscores
the importance of acknowledging group identity rather than an overarching American identity in exploring the race effect after
a national collective trauma. The consequential implications for disaster planning, future research investigation, and social
service delivery are discussed. 相似文献

ABSTRACTFor patients with disability who require funded supports to leave hospital, the introduction of the National Disability Insurance Scheme (NDIS) represents opportunity and challenges. At a time of major reform, timely and supported discharge is reliant on overcoming interface complexities. The purpose of this study was to examine the NDIS participant pathway timeframes against discharge expectations for hospitalised adults with spinal cord injury (SCI) or acquired brain injury (ABI) and interrogate delays for the two groups. Administrative data on 54 participants (ABI?=?18 and SCI?=?36) were analysed. Both groups experienced delays to discharge and significant variability in timeframes between NDIS pathway processes and extent of delays. Group differences were identified regarding inefficiencies across the continuum, with type of support a factor to investigate further. This study has uncovered critical points in the NDIS pathway that could impact discharge of participants and where collaboration and adaptive strategies could be targeted to improve processes.IMPLICATIONS
Ensuring the National Disability Insurance Scheme (NDIS) pathway operates effectively in the hospital setting is critical to the timely discharge of people with complex needs who require funded supports.
Monitoring implementation of the NDIS in the health setting is important to avert interface problems that impede timely discharge and access.

AbstractObjective: The current study examined the role of family influences on the vaccine behavior of emerging adults. Participants: In Spring 2017, we conducted anonymous online surveys of undergraduate students (n?=?608) at a large, public university in the mid-Atlantic. Methods: Logistic regression was used to examine associations between family factors and students’ awareness of the HPV vaccine, vaccine receipt, and vaccine intentions. Family factors included sex communication, religiosity, parental monitoring, family structure, and parents’ birthplace. Results: More comprehensive family sex communication is associated with less uncertainty regarding HPV vaccine receipt and greater likelihood of being already vaccinated. More frequent family religiosity and more parental monitoring are associated with greater likelihood of having decided against vaccination rather than already being vaccinated. Significant gender and racial disparities exist. Conclusion: Further research, policy, and programmatic intervention are needed to reduce disparities and to improve emerging adults’ compliance with HPV vaccine recommendations. 相似文献

AbstractObjective: Cocaine use is increasing. Comorbidities and diagnostic sequencing are needed among college students to inform treatment of cocaine use disorder (CUD). Method: Using electronic medical records from the psychiatric clinic at the student health care center of a large, public university from 2005 to 2015, patients diagnosed with CUD were identified. Their top mental health conditions were identified and assessed to see whether the first diagnosis of these conditions was made (1) before, (2) at the same time as, or (3) after the first diagnosis of CUD. Results: Among the 50 CUD patients, their most common mental health comorbidities were alcohol use disorder, anxiety, depression, and cannabis use disorder. Anxiety and depression were likely to be diagnosed before CUD; alcohol and cannabis use disorders were likely to be diagnosed concurrently with CUD. Conclusion: Diagnostic sequencing can be used to inform screening, workup, and treatment for patients with CUD. 相似文献

Injection drug users are at high risk for homelessness and human immunodeficiency virus (HIV) infection. This study sought to examine incidence rates and the social and economic antecedents of homelessness of impoverished inner-city injection drug users. Of the 569 participants, from a nontreatment sample who participated HIV prevention study, interviewed at baseline, 324 (57%) were reinterviewed 5.2 months later. At baseline 48% of the participants reported that they had been homeless in the past 10 years. Of the 324, 18% reported that at both interviews they had been homeless within the prior 6 months, 12% reported homelessness at baseline but not at follow-up, and 8% reported homelessness at follow-up but not at baseline. At baseline personal social support network characteristic of size of material aid and size of sex network was found to be associated with self-reports of homelessness. Baseline reports of presence of mother in personal network, size of material aid network, and network density were found to be associated with reports of homelessness at follow-up. These result suggest the need for alternative approaches to addressing issues of homelessness injection drug users. 相似文献

(Dis)respecting versus (Dis)liking: Status and Interdependence Predict Ambivalent Stereotypes of Competence and Warmth 总被引:1,自引:0,他引:1
As Allport (1954) implied, the content of stereotypes may be systematic, and specifically, ambivalent. We hypothesize two clusters of outgroups, one perceived as incompetent but warm (resulting in paternalistic prejudice) and one perceived as competent but not warm (resulting in envious prejudice). Perceived group status predicts perceived competence, and perceived competition predicts perceived (lack of) warmth. Two preliminary surveys support these hypotheses for 17 outgroups. In-depth analyses of prejudice toward particular outgroups support ambivalent prejudice: Paternalistic prejudice toward traditional women, as well as envious prejudice toward career women, results in ambivalent sexism (Glick & Fiske, 1996). Envious prejudice toward Asians results in perceived competence but perceived lack of social skills. Ambivalent content reflects systematic principles. 相似文献

Alcoholic beverage consumption among high school students has shifted from beer to liquor. The current longitudinal study examined the effects of beverage-specific alcohol use on drinking behaviors among urban youth. Data included 731 adolescents who participated in Project Northland Chicago and reported consuming alcohol in 7th grade. Logistic regression tested the effects of beverage-specific use on consequences (e.g., alcohol use in the past month, week, heavy drinking, and ever drunkenness). Compared to wine users, adolescents who reported drinking hard liquor during their last drinking occasion had increased odds of alcohol use during the past month (OR = 1.44; 95% CI = 1.01-2.05), past week (OR = 3.37; 95% CI = 1.39-8.18), and ever drunkenness (OR = 1.56; 95% CI = 1.07-2.29). Use of hard liquor was associated with increased risk of alcohol-related consequences. Early selection of certain alcoholic beverages (e.g., hard liquor) may result in negative health outcomes and problematic alcohol use over time. 相似文献
