In many countries, important features of municipal government (such as the electoral system, mayors' salaries, and the number of councillors) depend on whether the municipality is above or below arbitrary population thresholds. Several papers have used a regression discontinuity design (RDD) to measure the effects of these threshold‐based policies on political and economic outcomes. Using evidence from France, Germany, and Italy, we highlight two common pitfalls that arise in exploiting population‐based policies (compound treatment and sorting), and we provide guidance for detecting and addressing these pitfalls. Even when these problems are present, population‐threshold RDD may be the best available research design for studying the effects of certain policies and political institutions. 相似文献

Having an adult mentor during adolescence has been found to predict academic success. Building on previous work, the present study examined interactions between the type of mentor (i.e., kin, teacher, friend, or community), the time that mentor became important (i.e., before, during, or after high school), and the ethnicity of the protégé in predicting educational attainment in young adulthood. Analyses used Waves III and IV of the National Longitudinal Study of Adolescent Health (N = 2,409). Participants’ ages ranged from 18 to 27 (M = 21.75, SD = 1.79). The sample was 56.7 % female and nationally representative of ethnic diversity. Analyses showed that having a teacher-mentor was more predictive of educational attainment than having other types of mentors and that overall, having a mentor after high school predicts the most educational attainment. Kin- and community-mentors appeared to be more important to educational attainment during and before high school, respectively. Findings were consistent across ethnic groups. Overall, results highlight the value of teacher-mentors throughout childhood, adolescence, and early adulthood and our study further suggests that different types of mentors may be particularly useful at specific points in development. 相似文献

The primary aim of this study was to compare the willingness of sexually abused (n = 22) and non–sexually abused (n = 36) late adolescent women to self-disclose both general and sexual information to strangers and intimate partners. Results, based on a sample of college women, indicate that those who were sexually abused in childhood are less likely than nonabused counterparts to be highly disclosing of sexual and general information to intimate partners. Avoiding extensive disclosure of personal information to intimate partners may serve to keep survivors of abuse at a relatively safe distance from their own dysphoric feelings and suggests that mistrust of others is an ongoing issue for this population. 相似文献

Accident investigation is frequently cited as the cornerstone of an effective occupational health and safety program. We suggest that the literature on accident investigation is based on a model of witnesses as neutral and accurate recording devices. The literature on eyewitness testimony and criminal investigation offers strikingly different conclusions. We review these findings and point to their implication for research on accident investigation in occupational health and safety contexts. 相似文献
