民国时期国家为了强化对基层的控制与管理,陆续将现代的警察体系引入到乡村基层,以图改革中国传统的乡村治安体系。然限于警力缺乏等因素,这就导致了民国时期基层警察体系最为明显的一个特征便是存在名目繁多的警察之补助组织,这种状况的存在一方面反映了国家向基层政治的渗透,另一方面也反映了民国时期国家对基层控制之薄弱。  相似文献

A mutational spectrum measures the frequency of mutations at particular base pairs along a given DNA sequence under the influence of a particular treatment. Such spectra have been measured for several genes, in various organisms and under different treatments. This article presents a method of analysis based on the statistical discrimination between mutable base pairs and stable base pairs. The coefficients of the discriminant function characterize the mutational spectrum induced by a given treatment on a given sequence. These coefficients can be interpreted by the user without specialized statistical knowledge.  相似文献

国际直接投资的优势互补理论研究   总被引:1,自引:0,他引:1  
文章分析和借鉴了西方国际直接投资理论和竞争优势理论 ,提出了兼顾投资方与吸资方的国际直接投资理论系统。它的目标是取得新组合的竞争优势。国际直接投资理论系统分别由反映双方投资目标 (原因 )、条件及对象的优势要素互补系统 (静态系统 )、竞争优势实现系统 (动态系统 )和优势环境系统 (环境系统 )组成 ,三个系统互为条件和补充 ,是统一的整体。  相似文献

This article presents a general overview of "voluntary improvements" as one form of voluntary social provision within the Spanish social security system. To this end, the article analyses different forms of voluntary improvements from both a legal and a jurisprudential perspective. Particular attention is given to problems that are a major source of conflict. In line with employment practice, voluntary improvements are articulated through collective bargaining. Although intended to encourage private initiative in matters of social provision, such improvements are nonetheless guided by the social security system, not least as a means to control both funding and procedure.  相似文献

家长式领导和组织价值观对成员知识活动的影响机理   总被引:2,自引:0,他引:2  
根据知识基础的组织理论,从微观层面探索家长式领导和组织价值观对个体知识活动的影响机理。在理论上构建中介、交互和附加3种竞争性模型,提出家长式领导、组织价值观和个体知识活动三者之间的假设关系;采用问卷方式对191名医生进行调查,并采用层级回归分析对以上假设进行检验。实证结果表明,家长式领导和组织价值观对个体知识活动均产生影响,但二者地位取决于知识活动类型。对个体的知识创造活动,领导行为与价值观的影响是替代关系;对个体知识回避活动,二者是互补关系;对个体知识挪用活动,则相互独立。此外,家长式领导的威权领导与组织价值观的成员成长对知识活动同时存在消极和积极影响的悖论效应。  相似文献

We describe a quantitative methodology to characterize the vulnerability of U.S. urban centers to terrorist attack, using a place-based vulnerability index and a database of terrorist incidents and related human casualties. Via generalized linear statistical models, we study the relationships between vulnerability and terrorist events, and find that our place-based vulnerability metric significantly describes both terrorist incidence and occurrence of human casualties from terrorist events in these urban centers. We also introduce benchmark analytic technologies from applications in toxicological risk assessment to this social risk/vulnerability paradigm, and use these to distinguish levels of high and low urban vulnerability to terrorism. It is seen that the benchmark approach translates quite flexibly from its biological roots to this social scientific archetype.  相似文献

Past research has established that complementary stereotypes of men and women serve to justify the gendered division of labour as well as the division of labour in society at large. This paper is concerned with the essentialist lay theories for the origin of group differences (i.e. belief in genetic determinism vs. belief in social determinism) which may moderate the justificatory effect of complementary gender stereotypes. We present data from an experimental study conducted in Greece, in which genetic vs. social deterministic lay theories for group differences and complementary vs. non-complementary accounts of gender differences were crossed. In these data, complementary accounts of gender increased participants’ justificatory responses only when a genetic deterministic context was made salient; on the contrary, the social deterministic context appeared to buffer the justificatory function of complementary accounts of gender. The results extend the literatures on the justificatory effects of complementary stereotypes as well as on essentialism, and point to the importance of the historical context in which particular ideas and lay theories for intergroup differences are embedded.  相似文献

This qualitative study investigated the use of folk medicine by families for people with intellectual disability in the Philippines. Workers from Negros Occidental who support people with intellectual disability participated in semi-structured interviews. Findings show families seek the intervention of a folk healer before seeking primary healthcare support and a prosperous cultural use of folk medicine exists across the Philippines. Intellectual impairment is perceived by some Filipinos to be caused by supernatural forces. Socio-cultural constructs of intellectual disability probably influence health outcomes for this populace. If primary healthcare tools and resources for people with intellectual disability that are developed in higher-income nations are to have the potential to be transferred into other settings, understanding of attitudes towards alternative medicine is needed.  相似文献
