The social development model (SDM) is a theory of behavior that has proven useful in explaining the etiology of delinquency, violence, and substance use among adolescents as well as early antisocial behavior among pre-adolescents. A further test of the model is its generalizability across population groups. A section of the SDM representing prosocial influences in the etiology of problem behavior was compared for boys and girls and for children from low- and non low-income families using three waves of child, parent and teacher survey data on a sample of 851 elementary school students. Multiple group structural equation modeling was used to assess differences across groups in both measurement of model constructs and hypothesized structural paths between constructs. The results indicate overall similarity in the reliability of measurement models and validity of structural models.  相似文献

巨额财产来源不明罪的设立 ,对打击犯罪曾经起过积极作用。但随着经济的发展和时间的推移 ,腐败分子巨额财产来源不明的现象却屡禁不止、愈演愈烈 ,重要原因之一是由于刑法规定的该罪的量刑幅度畸轻。这不仅违背了罪刑相适应的原则 ,放纵了犯罪 ,而且为执法者徇私枉法开了方便之门。建议立法机构比照贪污、受贿罪的量刑进行修改 ,提高法定刑、增加量刑档次。  相似文献

由于职业的特殊性 ,警察的心理素质对其工作有着特殊的重要性。近年来 ,对警察心理素质的日益关注使得许多单位在选拔警察时都加强了对其心理素质的考核 ,但人们在热衷于心理测试的同时 ,却对测试中的公正性缺乏足够的关注。通过对访谈与测验两种测试方式在公正性上的比较 ,探讨警察心理测试技术中的公正性问题颇具现实意义。  相似文献

The purpose of this article is to reconsider the claim made recently by Mondak and Sanders that political tolerance ought to be thought to be a dichotomous rather than continuous variable. Using data from both Russia and the United States, I demonstrate that those Mondak and Sanders regard as uniquely tolerant are most likely no more than people who were given insufficient opportunity to express their intolerance. Even if such a phenomenon of “absolute tolerance” exists (all ideas expressed in all ways are to be tolerated), it is sufficiently rare that few practical implications are indicated for those doing empirical work on political tolerance and intolerance. * I appreciate the valuable comments of Jeffcry Mondak on an earlier version of this paper.  相似文献

This article assesses the privatisation of the electricity sector in two Caribbean countries, Jamaica and Trinidad and Tobago, to determine if they have been successful and whether they have contributed benefits to the respective societies. Two general methods are applied in assessing the success of the divestments; attainment of governments' stated objectives and commonly used utility performance metrics together with social and customer focus indicators. The results indicate that the stated objectives were broadly achieved, and the privatisation and its attempts brought benefits to the consumers and the society in general. The short to medium term benefits were accrued through lower labour costs per unit of electricity, higher performance of plant and operations and business led decision‐making. Long‐term benefits are accrued through the reduction or elimination of electricity supply deficits. However, although the basic privatisations were successful, the absence of an adequate regulatory framework in one case may have reduced the quantum of benefits through failure to enforce continuous improvement in the privatised generation company, and reductions in worker rents in the public distribution company. Further, benefits were reduced by long divestment processes, accompanying strategic drift, opportunity costs from delayed sale proceeds and efficiency enhancement, and the costs to sustain interim operations.

目的 基于二维超声剪切波测量联合血清肝纤维化和肝功能指标,探讨肝豆状核变性(hepatolenticular degeneration,HLD)患者中医证型与肝纤维化程度的相关性。方法 将89例HLD患者根据中医临床辨证分型分为痰瘀互结组(44例)、湿热内蕴组(33例)、肝肾阴虚组(12例)。比较二维超声剪切波测量指标和血清肝纤维化指标\[透明质酸酶(hyaluronidase,HA)、层黏连蛋白、Ⅳ型胶原、Ⅲ型前胶原N端肽\]、肝功能指标(血清天冬氨酸氨基转移酶、丙氨酸氨基转移酶、总胆红素)水平,并进行相关性分析。结果 3组患者门静脉内径比较,差异无统计学意义(P>0.05)。与痰瘀互结组比较,湿热内蕴和肝肾阴虚组剪切波速度均显著降低(P<0.05);与湿热内蕴组比较,肝肾阴虚组剪切波速度显著降低(P<0.05),脂肪衰减系数显著减小(P<0.05)。与痰瘀互结组比较,肝肾阴虚组HA水平显著降低(P<0.05),其他生化指标各证型组之间比较,差异均无统计学意义(P>0.05)。3种证型患者剪切波速度与HA存在正相关(P<0.05)。鉴别痰瘀互结证与湿热内蕴证、痰瘀互结证与肝肾阴虚证时,以剪切波速度的诊断价值最高;鉴别湿热内蕴证与肝肾阴虚证时,以脂肪衰减系数的诊断价值最高。结论 HLD的肝肾阴虚、湿热内蕴、痰瘀互结证型中的肝纤维化程度存在显著差异,以痰瘀互结证的肝纤维化程度更明显,与剪切波速度、脂肪衰减系数、HA密切相关。  相似文献

《侵权责任法》仅列举了侵权补充责任的数类适用情形,缺乏统一的客观适用标准,亦未明确具体的适用规则.责任分担是责任成立的后续命题,不应再以责任构成原理为立论基点,而应以外部被侵权人受偿及内部各侵权人终局责任分担为考量因素.按份、连带责任的终局责任分担困境及不真正连带责任全额赔偿的僵化,使得补充责任不可或缺.由该正当性可推知,侵权补充责任应适用于“具有全部原因力的直接作为侵权+过失不作为侵权”之一般情形.补充责任人应承担与过错、原因力相当的补充责任,并可向直接责任人全额追偿.  相似文献

缓刑在不同的刑事诉讼阶段所表现的主要特性是不同的,因而对其性质进行分阶段的界定也就有了现实的依据和合理性。从决定是否对犯罪分子宣告缓刑的意义上来说,缓刑有刑罚裁量的性质;从对犯罪分子具体适用缓刑的各项规定的意义上来说,缓刑又具有刑罚执行的性质。缓刑,兼具刑罚裁量和刑罚执行两重性质。在明确缓刑具有刑罚执行的法律性质的前提下,认定缓刑考验期满后再犯相应之罪的犯罪分子为累犯,就有了理论以及法律上的合理性。此种处置,从一般预防和特殊预防的角度来看,既符合中国社会重视行为人主观意志的现实,又能更好发挥刑罚预防犯罪的功能,也是符合我国现行刑事政策和法律规定的。  相似文献

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

  • Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
  • Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
  • These metrological principles also apply to individuation of unique objects in general.
