We use matched employee–employer records from the teacher labor market to explore the effects of late teacher hiring on student achievement. Hiring teachers after the school year starts reduces student achievement by 0.042 SD in mathematics and 0.026 SD in reading. This reflects, in part, a temporary disruption effect in the first year. In mathematics, but not in reading, late‐hired teachers remain persistently less effective, evidence of negative selection in the teacher labor market. Late hiring concentrates in schools that disproportionately serve disadvantaged student populations, contributing to challenges in ensuring an equitable distribution of educational resources for all students.  相似文献

Conclusions The history of U.S. and Canadian risk assessments for dioxin is an increasingly familiar tale of debates within the scientific community played out in the political arena. Uncertainty among scientists creates the possibility of large disparities between different governments' policies. However, the pattern of differences that emerges reflects the context in which science policy decisions are made within each agency and within each country. The political environment has implications not just for how mandated science is received, but for how it is conducted.Many features of the dioxin case are consistent with observations by others. In the cases of formaldehyde, alachlor, alar, and amaranth, EPA relied on mathematical models to assess the risks of potential carcinogens, while Health and Welfare Canada relied on the more traditional safety factor approach.35 This body of evidence is suggestive of national styles of transscience. Features of the U.S. style include explicit rationales for regulatory decisions, reliance on consistent and explicit risk assessment principles, and public debate over scientific aspects of public policy. The Canadian style is exemplified by closed decisionmaking, case-by-case review, and the absence of public discussion of the scientific basis for government decisions.The differences between FDA and EPA in this case study suggest an important caveat, however. The U.S. style is most clearly reflected in the implementation of the non-discretionary environmental, health and safety statutes passed by the U.S. Congress since 1970. More closed and traditional styles of regulatory decisionmaking may survive within the U.S. as vestiges of a more deferential past.Even less than pure science, trans-science is not a universal enterprise. When scientists do reach agreement, it can be a powerful force that can even overcome political and national differences (Haas, 1989). However, when science is uncertain, as is typically the case in assessing the risks of toxic chemicals, there is more room for political factors to shape the way different countries interpret science in making policy decisions.  相似文献

This study explores the extent to which women interested in careers in criminal justice tend to express interest in the female-role—compatible specialties within the field as compared to men and as compared to more traditionally male specialties. A sample of 288 criminal justice students was surveyed and the data revealed that females did express higher interest in female-role—compatible specialties both as compared to the males surveyed and as compared to their interest in most of the traditionally male positions. The results are especially noteworthy in that occupational areas recently opened to women (most especially police patrol officer) were of relatively low interest to those women as compared to traditionally female areas.  相似文献

In this article, we introduce and utilize a new dataset that provides battle- and war- level Loss Exchange Ratios (LERs) for combatant states involved in multilateral wars between 1816 and 1990.The battle-level data provide an alternative to the widely used, but problematic, HERO/CDB-90 data set on battle outcomes. To demonstrate the utility of the new data, we weigh in on the debate over democratic military effectiveness arguments by replicating models by Reiter and Stam (2002, 2009) and Downes (2009), finding that, when effectiveness is measured using LERs, democracies do not have an edge over their non-democratic counterparts.  相似文献

In Bangladesh, dramatic social and economic changes are transforming historical forms of patriarchy with various impacts on pathways to women's empowerment. We hypothesised contemporary resources would be more strongly associated with women's empowerment, as reflected in their influence in family decisions. In cross-sectional analysis, we found the contemporary resources of employment and membership in NGOs were most strongly and consistently associated with women's influence in family decisions. Education was only modestly associated, as were customary resources, including age and fertility. Programmatic efforts to enhance women's empowerment should consider the rapidly changing environment and the importance of women's economic participation.  相似文献

This review of the literature aims to guide practitioners concerned with ameliorating the psychosocial effects for rural-dwelling children from homes where methamphetamine is used or produced. Although a substantial body of research exists regarding the environmental dangers and physical health risks to children from methamphetamine-affected homes, there is a paucity of research regarding child psychosocial outcomes. This article summarizes the published literature examining family contexts and psychological and behavioral consequences for children. Implications of this body of knowledge for child welfare practitioners, limitations of the studies reviewed, and future research directions are discussed.  相似文献

Some research suggests that the risk of physical aggression by an intimate partner is related to marital status, but this relationship may vary across cultures and by gender. In the present study, we systematically examine the relationship between marital status and physical partner aggression by gender across 19 countries. Logistic and multilevel regression confirmed previous findings of lower rates of physical aggression for legally married versus cohabiting and separated/divorced women and men across most, but notably, not all countries. Single status was associated with higher risk in some countries and lower in others reflecting possible cultural differences in risk for different marital statuses. For example, single women had significantly lower rates of victimization than did married women in India where violence against wives is often accepted. The variation in the cross-cultural findings highlights the importance of examining both men and women and considering the cultural context when interpreting the relationship between partner aggression and marital status.  相似文献

ABSTRACT

To succeed, the Housing Choice Voucher (HCV) program must be attractive to rental property owners. When landlords refuse to accept subsidized renters, lease-up rates decline, administrative costs increase, and options become limited to high-poverty neighborhoods where owners are most desperate. This article examines what motivates landlords’ decisions to accept subsidized tenants. We use 127 interviews with a random and field sample of landlords, combined with administrative data from the U.S. Department of Housing and Urban Development on property ownership in Baltimore, Maryland, Dallas, Texas, and Cleveland, Ohio. We find that landlords’ perspectives on the HCV program, including rents, tenants, and inspections, are highly dependent on context; landlords weigh the costs and benefits of program participation against the counterfactual tenant that a landlord might otherwise rent to in the open market. We argue that policymakers can boost landlord participation by better understanding how landlords think about their alternatives within each local context. Finally, we consider what drives nonparticipation in the program. Our results show that the majority of landlords who refuse voucher holders had accepted them previously. We suggest that policy reform should be dually focused on improving bureaucratic inefficiencies that deter landlord participation, and providing training and education to landlords.  相似文献
