The implementation of the Surface Mining Control and Reclamation Act (SMCRA) of 1977 in coal producing states is guided by a partial preemption policy approach t h a t establishes a balance between federal and state decision-making authority. The usefulness of this approach is assessed by analyzing state enforcement actions in relation the institutional capacity of states to shoulder regulatory responsibilities and the propensity of the federal Office of Surface Mining (OSM) t o oversee state enforcement actions and, if necessary, to undertake corrective action. Our results indicated that state administration of SMCRA was canstrained by the lack of effective federal oversight but was largely unaffected by interstate differences in political, economic, or administrative characteristics.  相似文献

The circumferences of the four intact cardiac valves were measured during 397 coroner's autopsies using an obturator cone to assess the value of this measurement in the postmortem diagnosis of cardiac disease. Valve sizes of cases with cardiac and noncardiac causes of death were compared using logistic regression to assess the effects of confounding variables including sex, age, height, build and the presence of chronic obstructive airways disease. Mitral valve enlargement was found to be significantly associated with cardiac death, as were build, age, and sex. Measurement of the mitral valve at autopsy can help distinguish cardiac from noncardiac causes of death.  相似文献

Among a number of widely used risk assessment instruments with adult sexual offenders, the Minnesota Sex Offender Screening Tool-Revised (MnSOST-R) has been subject to relatively few evaluation studies. Only two independent research groups have published replication studies in the peer-reviewed literature with data not provided by the MnSOST-R's developers, and the results regarding the accuracy of predicting sexual recidivism have been mixed. In this article, important differences between the Barbaree et al. and Langton et al. studies are presented. Analyses reported for the various subsets comprising these two samples indicate that coding discrepancies in the Barbaree et al. study account for the different findings, with a moderate level of predictive accuracy using the Receiver Operating Characteristic curve ultimately found for the MnSOST-R in both data sets.  相似文献

This study of 784 inmates in a boot camp in a southern state was designed to determine what elements from life-course theory distinguished between graduates, dropouts, and dismissals from the program in this facility. Multinomial logistic regression analysis showed that several social bonds—such as employment, income, marital status—and personal assets like self-efficacy differentiated graduates from dropouts and dismissals from that program. In contrast, selling drugs, illegal income, and carrying a weapon also were associated with graduation.Lack of self-control, drug use, and peer association differentiated dropouts from graduates, whereas history of being abused, emotional problems, and suicidal attempts distinguished dismissals from graduates. The implications of these findings for further research and current decision-making are discussed.  相似文献

The goal of this study was to evaluate the contribution of family characteristics (family conflict and cohesion) and abuse characteristics (age at which abuse occurred, abuse severity, and relationship to perpetrator) to resilience (self-acceptance, ability to engage in positive relationships with others, and environmental mastery) in a sample of one hundred and 77 university women who had experienced childhood sexual abuse (CSA). The respondents completed a questionnaire that focused on childhood experiences including family environment in childhood, characteristics of the abuse they had experienced in addition to degree of current resilience defined as their level of well-being (self-acceptance, ability to engage in positive relationships with others, and environmental mastery). The results indicated that family characteristics accounted for 13–22% of the variance in the well-being outcomes. In contrast, abuse characteristics accounted for 3% or less of the variance in the well-being outcomes. The clinical implications of these findings are discussed.  相似文献

Contemporary democracies show considerable differences in the issue composition of their protest politics, which tends to remain relatively stable over time. In countries like Germany or the Czech Republic, the vast majority of protests have been mobilised around sociocultural issues, such as human rights, peace, nuclear power or the environment, and only a tiny portion of protest has focused on economic issues. At the opposite extreme, protest in France or Poland usually has a strongly economic character and voices demands relating to material redistribution and social policy. What lies behind the cross-country differences in national protest agendas? In this article, the national protest agenda depends on what issues mainstream political parties are contesting: the content and strength of the master-issue dimension. In reference to the literature on the multidimensional political space and niche political parties, one should expect that there is a substitutive effect; where the stronger a specific master-issue dimension is in party politics, the less salient that issue dimension is in protest politics. This substitutive effect results from the tendency of electoral politics to reduce political conflict to a single-dimension equilibrium, which decreases the importance of other issues and relegates the contest over secondary, niche issues to the realm of policy-seeking strategies, with protest being a common type of this political strategy. In party systems where single-dimension equilibrium does not exist and the master-issue dimension is weaker, the same dynamics result in a more convergent relationship between party and protest politics and a greater similarity between the protest- and party-system agendas. To investigate this theory, the national protest agendas in four countries are examined. The Czech Republic, Hungary, Poland and Slovakia show four combinations of two crucial factors that are not available in the old Western democracies: the content and the strength of the master-issue dimension. The study draws on an original dataset of protest events organised in the four countries between 1993 and 2010, and on qualitative and quantitative data on issue dimensions of party politics obtained from studies on party politics and expert surveys. The results show that in the Czech Republic, where the master-issue dimension has remained strongly economic, protest has been predominantly sociocultural. In Poland between 1993 and 2001 and Hungary between 1993 and 2006, the master-issue dimensions are strongly sociocultural, while protest is predominantly economic. There is no single-dimension equilibrium in party politics in Slovakia or in post-2001 Poland and mainstream parties compete on both economic and sociocultural issues. Consequently, the substitutive dynamics between party and protest politics is weaker and the issue agendas in party and protest arenas are here more alike.  相似文献
