Federal initiatives since 1996 have intensified the efforts of states to achieve adoption for children in foster care. For many waiting children, the path to adoption is long. The authors offer an economic analysis of adoption from foster care, with an emphasis on the reasons why achieving the goal of adoption for all waiting children may be so difficult. The authors then estimate the determinants of adoptions from foster care across the states using data for fiscal years 1996 and 1997. Adoption assistance subsidy rates stand out as the most important determinant of adoptions from foster care, followed by use of alternatives (e.g., intercountry adoption). Adoptive matching on the basis of race does not appear to prevent adoptions from foster care in the aggregate, leaving flaws in the matching process, such as a lack of information and difficulty using the Interstate Compact on the Placement of Children (ICPC), as a primary reason why children wait.  相似文献

Norm setting has been shown to be a crucial element of effective drug education. The purpose of this study was to examine the degree to which a videotape describing concepts and methods for establishing positive norms would enhance standard training. Participants included 35 teachers and 64 health education students who were randomly assigned to the standard training condition or the video-enhanced training. Participants completed pretest and posttest measures of beliefs, attitudes, and knowledge concerning prevention methods. Both the standard and the video-based instruction produced improved understanding of norms and norm setting prevention methods. However, the video-based instruction resulted in several notable improvements beyond what was achieved in standard instruction. Video training can be an important tool as research-based drug abuse prevention achieves wide-scale dissemination. It offers a way of standardizing training and has the potential to increase the fidelity with which prevention programs are implemented.  相似文献

Prior studies have paid attention to the influence of domestic experience on internationalization, for which domestic experience primarily refers to the accumulation of internationalization knowledge from industrial peers or partners at home. We argue that the commonalities and differences between international experience and domestic cross-regional experience have not been fully incorporated in previous frameworks in the literature. Thus, in untangling the commonalities, we purposively differentiate domestic experience into two dimensions, i.e., repetition-based experience and diversity-based experience, to investigate the contingent role of making domestic cross-regional investments in shaping the relationship between international experience and the speed of internationalization. We expect that these two dimensions of domestic experience will moderate the relationship between international experience and the speed of internationalization in a different way. More specifically, repetition-based experience has a negative moderating effect while diversity-based experience has a positive moderating effect. Further, considering the differences between international investments and domestic investments, we expect that the joint impacts of international experience and domestic cross-regional experience on internationalization speed are contingent on whether firms have sufficient resources to support multiple learning or whether institutions between the home country and foreign country is similar enough for cross-context application. We expect that financial slack and institutional distance between prior foreign entries' country and the home country play significant three-way moderating roles in setting boundaries for the relationship between domestic experience and international experience. Based on the analysis of 302 Chinese publicly listed firms from 2001 to 2014, the dynamic panel data regression results support our hypotheses. Overall, our simultaneous consideration of commonalities and differences between domestic investments and international investments sheds light on how MNCs learn from both international and domestic investments to speed up their foreign expansions.  相似文献

In this article we examine what affects the board of directors’ involvement in the advice to management, with emphasis on the influence of crises on the board advisory tasks performance. Based on a survey of 881 small Norwegian firms, we analyse responses from CEOs in order to determine whether and to what extent the board is actively involved in the governance process during crises through providing advice. The study has two major contributions to board research in general and research of into small firms in particular. The first is the go beyond the “usual suspects” of board size, CEO duality, and board independence when looking for determinants of board involvement in advice. The second contribution is a clearer understanding of board involvement during crises. Our results show that board member diversity becomes particularly important during crises, since this provides the CEO and firm access to a more diverse pool of competences and experiences. We also find that crises moderate the effects of incentive on the board’s involvement in advice. This evidence sheds new light on the determinants of directors’ involvement in board tasks, suggesting that directors’ incentive to perform certain board tasks vary according to the contingent situation the firm is experiencing.  相似文献

CCA-treated wood is widely used in the fabrication of outdoor decks and playground equipment. Because arsenic can be removed from the surface of CCA-treated wood both by physical contact and by leaching, it is important to determine whether children who play on such structures may ingest arsenic in quantities sufficient to be of public health concern. Based on a review of existing studies, it is estimated that arsenic doses in amounts of tens of micrograms per day may be incurred by children having realistic levels of exposure to CCA-treated decks and playground structures. The most important exposure pathway appears to be oral ingestion of arsenic that is first dislodged from the wood by direct hand contact, then transferred to the mouth by children's hand-to-mouth activity. The next most important pathway appears to be dermal absorption of arsenic, while ingestion of soil that has become contaminated by leaching from CCA-treated structures appears to be of lesser importance, except possibly in the case of children with pica. Considerable uncertainty, however, is associated with quantitative estimates of children's arsenic exposure from CCA-treated wood. Priorities for refining estimates of arsenic dose include detailed studies of the hand-to-mouth transfer of arsenic, studies of the dermal and gastrointestinal absorption of dislodgeable arsenic, and studies in which doses of arsenic to children playing in contact with CCA-treated wood are directly determined by measurement of arsenic in their urine, hair, and nails.  相似文献

Resistance training (RT) improves overall health, but the psychological effects of RT in healthy old adults have not been tested. The aim of this study was to investigate a sample of 65–70-year-old healthy and physically active women to assess their sense of coherence, health-related quality of life, hope, and affect, before and after taking part in a 24-week RT intervention (N = 14), compared to controls (N = 18). Findings showed a significant increase in hope (p = 0.013) and a significant decrease in negative affect (p = 0.002). Starting RT after age 65 does not appear to negatively impact on women’s psychological health but seems to be associated with important psychological health benefits.  相似文献

The present research investigated how temporal distance affects imitation of gestures during a conversation. According to construal level theory, psychological closeness (vs. distance) leads to preference for more pictorial and embodied (vs. symbolic and amodal) forms of communication as well as to greater context sensitivity. We thus hypothesized that people are more sensitive to the contextual meaning of gestures and show more imitation of meaningful (vs. meaningless) gestures when primed with temporal closeness (compared to distance). Participants (N = 91) were assigned to the role of a job interviewer for an internship that would begin in 1 week (vs. in 1 year) and interacted with an ostensible applicant who displayed various meaningful and meaningless gestures. When the internship was to start in 1 week, participants imitated meaningful gestures more often than meaningless gestures. When the internship was to start in 1 year, participants imitated both gesture types equally frequently. This finding indicates that people are more likely to embody verbal statements of an interaction partner when feeling psychologically close to the subject of the conversation.  相似文献
