This article presents a longitudinal examination of the association between children's experiences of child maltreatment (CM) and intimate partner violence (IPV), alone and in combination, with children's academic performance. Integrated, administrative data from the Minnesota Departments of Education and Human Services were used to obtain a sample of 2,914 children. Data provided an opportunity to study comparisons of single (CM or IPV) and combined experiences (CM-IPV), longitudinally observe the impact of these experiences on academic functioning, and make comparisons to the general population. Results revealed significant differences in school attendance and math and reading performance by adverse experience. Children exposed to CM and IPV, individually or in combination, underperformed at school. IPV-exposed children had the poorest outcomes. Findings highlight the need for dedicated screening for adverse childhood experiences, particularly IPV exposure, and devoting greater educational and social service resources as a means of promoting future school achievement and adult functioning.  相似文献

This research tests whether the effects of assessments of presidential performance on the senate voting decision are largest for out-party incumbents and smaller for out-party incumbents and candidates in open-seat contests, a pattern suggested by the restricted in-party culpability thesis. Analysis of data from the 1988–1990–1992 Pooled Senate Election Study reveals that the effects of appraisals of presidential performance are greatest in open-seat contests and those with in-party incumbents, contrary to the restricted in-party culpability thesis. For incumbents of the out-party and candidates in open-seat contests, the effects of assessments of presidential performance are principally a function of the competitiveness of the contest. Assessments of presidential performance shape the voting decision in contests with in-party incumbents regardless of the level of electoral competitiveness.  相似文献

Coalition governments are the norm in parliamentary democracies. Yet, despite the predominance of this type of government, political scientists have only recently started to investigate how voters approach elections when a coalition government is the likely outcome. Such elections present additional uncertainty and complexity for voters compared with elections in plurality systems, where party choice translates more directly into a choice of government. These factors have lead to the assumption that strategic voting is unlikely to occur in systems that produce coalition governments. In this introductory article to the special issue on Voters and Coalition Governments, we consider whether voters have the capacity to anticipate specific coalition outcomes and propose a framework for understanding the conditions that lead to strategic voting in both plurality and proportional systems.  相似文献

Whereas the classic literature on strategic voting has focused on the dilemma faced by voters who prefer a candidate for whom they expect has little chance of winning a seat, we consider the dilemma faced by voters in PR systems who do not expect their preferred party to be in government. We develop hypotheses relating to strategic voting over multi-party governments that we test using the New Zealand Election Study (NZES) campaign study of 2002. We find evidence that expectations play a role in structuring vote choice. While there is clear evidence of wishful thinking there is also evidence that voters respond to expectations about government formation. These expectations may mobilize voters and lead them to defect from their first preference.  相似文献

Just over a decade since the failed referendum of 1998, statehood for the Northern Territory (NT) is back on the political agenda. The achievement of statehood would be a first for Australian federalism, where no new state has been created or admitted since Federation. Following a discussion of the concept of statehood and how it might be achieved, it traces the political development of the NT. The article then examines the implications of NT statehood for the Australian federation and finds that statehood would facilitate constitutional change in the federation by lowering the threshold required for success in a national referendum. Statehood may also raise questions about the equal representation in the Senate of less populous states. However, statehood would have no effect upon financial arrangements with the Commonwealth, the standing of the Northern Territory at COAG meetings, or the legal standing of the other states.  相似文献

The adoption of the civil service system is the most comprehensive reform of the personnel system in the history of the People's Republic of China. The reformers want to establish a highly qualified and professional administrative corps. Elements of the reform include a merit‐based performance evaluation system that rewards good employees and punishes poor ones, open and fair competition in recruitment and promotion to assure the quality of government officials, and a system based on law that provides continuity and consistency for government policies. The article summarizes case studies of implementation challenges such as recruitment, examinations, selection and promotion, performance evaluation, training, job rotation and salary systems. The cases provide snapshots of some of the most difficult issues involved in reforming China's civil service. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Traumatic cardiac ventricular ruptures in children are rare. Only a single case of left ventricular rupture due to child abuse has been reported. We report a child who sustained a fatal left ventricular apical rupture. It appeared to have resulted from hydrostatic forces resulting from abusive blunt thoracic injury. That he was being abused was previously missed when he was presented to the emergency department with facial pyoderma. It was not noted that he also had lip and oral mucosal injury, sites not affected by staph toxins. As a result, his underlying, abusive and secondarily infected, facial flow type scald burn was not appreciated. Within a week thereafter his fatal injury occurred, accompanied by extensive and obvious associated abusive injuries. Postmortem high‐detail whole body computed tomography scanning aided the autopsy. Although rare, ventricular rupture from abusive blunt thoracic injury can occur.  相似文献

Forensic casework from past‐conflicts relies on the corrected historical Trotter data for stature estimation in Fordisc. For roughly 10 years’, stature estimation using this data has produced point estimates for the tibia that are on average 1.25 inches less than the other long bones. This issue was identified after applying the equations derived from Fordisc to the USS Oklahoma commingled assemblage. Reevaluation of Fordisc revealed that a correction factor of 20 mm, instead of 10 mm, was mistakenly applied to the Trotter tibia data. Historical forensic anthropology reports written at the Defense POW/MIA Accounting Agency were utilized to identify that the overcorrection is isolated to Fordisc 3 with an error rate of 5% of known antemortem statures falling outside of the prediction intervals that relied on the tibia. Further evaluation of the Oklahoma sample indicates the 10 mm correction is still producing point estimates less than the other long bones.  相似文献
