Abstract In recent years, church burnings in the South have attracted a great deal of attention. Many commentators have charged that they are a product of strained race relations throughout the South, and particularly of severe racial tensions in Southern rural areas. In this study we evaluate these claims. We begin by mapping the spatial coordinates of recorded church burnings from 1990 to 1997, and find that church arsons indeed are concentrated in the South. Church burnings, however, are a more urban phenomenon than popular media accounts would suggest. Our analysis then explores the influence of contextual factors (population and locale, racial composition and inequality, so‐cioeconomic conditions, local religious ecology, and patterns of reported crime) on church burnings in counties located in the study region. Logistic regression models confirm that church arsons are most likely to occur in small metropolitan statistical areas (MSAs) and non‐MSA counties containing a city of at least 10,000 residents. Church burnings also are especially likely in counties with a higher percentage of black residents, a larger number of churches relative to the rest of the state, and a higher arson rate. We conclude by discussing the implications of these findings for future research and public policy. 相似文献

分别用P_(204),P_(507),PSO—Ⅱ单独萃取混合氯化稀土,得到了萃取稀土的最佳条件,并对P_(204)与PSO—Ⅱ、P_(507)与PSO—Ⅱ,协同萃取稀土元素进行了初步探讨,发现P_(204)与PSO—Ⅱ,P_(507)与PSO—Ⅱ两者在萃取混合氯化稀土的试验条件下,均无协同效应。 相似文献

Many studies have provided evidence that, in birds, inexperienced breeders have a lower probability of breeding successfully. This is often explained by lack of skills and knowledge, and sometimes late laying dates in the first breeding attempt. There is growing evidence that in many species with deferred reproduction, some prebreeders attend breeding places, acquire territories and form pairs. Several behavioural tactics assumed to be associated with territory acquisition have been described in different species. These tactics may influence the probability of recruiting in the breeding segment of the population, age of first breeding, and reproductive success in the first breeding attempt. Here we addressed the influence of behaviour ('squatting') during the prebreeding period on demographic parameters (survival and recruitment probability) in a long-lived colonial seabird species: the kittiwake. We also investigated the influence of behaviour on reproductive trajectory. Squatters have a higher survival and recruitment probability, and a higher probability of breeding successfully in the first breeding attempt in all age-classes where this category is represented. The influence of behaviour is mainly expressed in the first reproduction. However, there is a relationship between breeding success in the first occasion and subsequent occasions. The influence of breeding success in the first breeding attempt on the rest of the trajectory may indirectly reflect the influence of behaviour on breeding success in the first occasion. The shape of the reproductive trajectory is influenced by behaviour and age of first breeding. There is substantial individual variation from the mean reproductive trajectory, which is accounted for by heterogeneity in performance among individuals in the first attempt, but there is no evidence of individual heterogeneity in the rate of change over time in performance in subsequent breeding occasions 相似文献

Finding optimal, or at least good, maintenance and repair policies is crucial in reliability engineering. Likewise, describing life phases of human mortality is important when determining social policy or insurance premiums. In these tasks, one searches for distributions to fit data and then makes inferences about the population(s). In the present paper, we focus on bathtub‐type distributions and provide a view of certain problems, methods and solutions, and a few challenges, that can be encountered in reliability engineering, survival analysis, demography and actuarial science. 相似文献

"十五"期间,河南高等教育事业取得突飞猛进的发展,但与广大人民群众"有学上"、"有好学上"的需求仍有一定差距,服务河南经济社会发展的能力还不够强,根源主要在于河南高等教育优质资源比较匮乏,突出表现在重点大学、重点学科和重点实验室较少方面.推动河南高等教育高水平发展,必须有针对性地加大"三重"建设力度,在学科建设等五个方面狠下工夫. 相似文献

以《中庸》为个案 ,从宋明道学的视野来观察船山的《四书》诠释。可以认为 :船山读《中庸》说 ,其中以未发说和戒慎说为其核心。船山有关《中庸》的讲法 ,可以说是“接着”程朱讲的 ,但不是“照着”程朱讲的 ;他不是传统意义上的程朱学派 ,但受到程朱学派的较大影响。船山虽然并不承认自己为程朱学派的一员 ,但顺承程朱《中庸》解说的脉络 ,延续程朱《中庸》诠释的问题性 ,吸取程朱许多的理学观念和诠释学资源 ,同时又针对朱子本人及朱门后学的论点而提出自己的诠释主张。船山的《中庸》解释是明清之际儒学经典诠释的一部分 相似文献

企业诚信不仅是良好市场经济秩序的基础,同时也是经济高质量发展的重要内容.本文以国家税务总局公布的2014—2018年上市公司纳税诚信状况作为企业诚信的衡量指标,考察企业诚信经营对企业全要素生产率的影响.研究发现,诚信企业的全要素生产率显著高于非诚信企业;企业诚信会通过促进研发创新以及优化内部控制来提高企业全要素生产率.异质性分析表明,企业诚信对低市场化进程地区企业、国有企业全要素生产率的促进作用更为显著.研究结论不仅为推进我国企业诚信建设提供经验证据,也为企业转型升级、实现高质量发展提供路径参考. 相似文献
