This study examined age differences in eyewitness testimony. Children, three and six years of age, and adults interacted with an unfamiliar man for 5 minutes. Four or five days later, the witnesses answered objective and suggestive questions, recalled what happened, and tried to identify the confederate from a target-present photo line-up. The adults and 6-year-olds did not differ in their ability to answer objective questions or identify the confederate, but 6-year-olds were more suggestible than adults and recalled less about the event. Compared to the older age groups, the 3-year-olds answered fewer objective questions correctly, recalled little about what happened, and identified the confederate less frequently. In addition, they were the most suggestible. The experiment extends our knowledge of children's ability to provide accurate eyewitness reports to a very young age group and to a situation in which participants are not merely bystander witnesses but instead directly interact with the confederate.  相似文献

Using data from the Child Care Supplement to the Fragile Families and Child Wellbeing Study, we test associations between the quality of child care and state child care policies. These data, which include observations of child care and interviews with care providers and mothers for 777 children across 14 states, allow for comparisons across a broader range of policy regimes and care settings than earlier research on this topic. Using multilevel linear and logistic models, we found that more generous subsidy policies (that is, greater investment, higher income eligibility) were positively associated with the quality of care in nonprofit child care centers, as well as with the use of center care. The stringency of regulations (that is, teacher education requirements, teacher‐child ratios/thresholds) was also associated with both quality and type of care, but in more complex ways. Higher teacher training requirements were positively associated with the quality of both family child care and nonprofit centers, while more stringent regulations decreased the number of children attending center care. No links were found between state policies and the quality of for‐profit center care. The implications for policy makers, advocates, and policy analysts are discussed. © 2007 by the Association for Public Policy Analysis and Management  相似文献

This article explores the conditions that allow judicial councils and impeachment juries to promote judicial autonomy. In theory, these bodies intervene in the appointment and removal of judges in order to reduce executive control over court composition, thereby promoting judicial independence. Using the case of Argentina at the federal and the subnational levels, this study demonstrates that competitive politics enhances the capacity of judicial councils and impeachment juries to bolster judicial autonomy. Interparty competition provides incentives for the executive to develop a meaningful system of checks and balances, which includes an independent judiciary that can check executive power. In contrast, monolithic party control—defined as a prolonged period of unified government under a highly disciplined party—permits the executive to maintain a monopoly on power and thereby control judicial appointments and removals.  相似文献

This study examines the psychosocial risks associated with body weight (BMI) and body image in a southeastern, rural Lumbee American Indian community. A total of 134 adolescents (57% female) were surveyed over 2 years at ages of 13 and 15 years. On average, boys (55%) were more likely to be overweight or obese than were girls (31%). BMI was related to a variety of weight control efforts including onset and frequency of smoking, dieting, and body dissatisfaction. Body dissatisfaction was associated with peer relations, self-esteem, anxiety, depression, and somatization in adolescence. Longitudinally, psychological health, peer competence, and ethnic identity were associated with positive body image. In boys, early ethnic identification was associated with the development of later body image. Implications of findings for ethnic- and gender-specific interventions are discussed.On faculty at Tulane University.

Suicide by self-inflicted blunt force injury is rare. The authors report a case of a 48-year-old man who initially appeared to have died of a homicidal beating. The pertinent autopsy findings consisted of blunt force closed head injury combined with numerous cutaneous abrasions and contusions of the entire body. Further inquiries confirmed a medical history of paranoid schizophrenia and a previous attempt at suicide. This case represents an extreme example of severe blunt trauma sustained during fatal self-mutilation and masquerading as a homicide. It also underscores the importance of correlating a thorough background investigation with autopsy findings in determining the appropriate manner of death.  相似文献
