近代尚力思潮是中国先进知识分子的觉醒和呐喊,对中国社会的发展进程、振兴中华民族体魄曾产生极其深远的影响,而现代尚力精神则是近代尚力思想的继承与发展,对现代文明社会因科技异化与社会物化而引发的"新文弱"群体扩大化将起到积极的影响.  相似文献

A 60 bp sequence variation hotspot in the canine mitochondrial DNA hypervariable region 1 was evaluated for its use in forensic investigations. Nineteen haplotypes containing 18 single nucleotide polymorphisms were observed among laboratory-generated and GenBank-derived domestic dog sequences representing five regional localities in the U.S. Samples from the different localities were highly variable with the levels of intra-population variability being similar among the populations studied. AMOVA further confirmed that there was no significant genetic structuring of the populations. Assays using these haplotypes were robust, canid specific and portend a rapid method for correctly excluding individual dogs as noncontributors of forensic evidence. Species-specificity of the primers was confirmed by means of in-tube polymerase chain reaction of human and cat DNA and in-silico assessment of the genomes of several animal species. Breed-specific fragments were not detected among the common haplotypes but there is evidence that this assay may be capable of differentiating domestic dog, wolf, and coyote sequences.  相似文献

Literature on political support broadly offers three micro-level models: socio-economic status, democratic process evaluations, and political performance evaluations explain people's differences in satisfaction with democracy. While tests show that these explanations complement each other, we do not know how. We combine for the first time all three models into one common longitudinal framework by explicitly considering aspects of time. We argue that relatively stable factors, such as socio-economic status, only explain general levels, whereas more time-sensitive factors, such as evaluations, explain differences between citizens at specific points in time. The results of latent growth curve modelling applied to nine-wave panel data support our general hypothesis of a common longitudinal framework. These results also show that economic evaluations play a prominent role as do some (but not all) electoral results. The findings have theoretical and methodological implications, and they offer a new perspective on the meaning of ’satisfaction with democracy’.  相似文献

所谓弱势群体,是指在市场经济条件下,社会成员中处于竞争弱势的阶层和群体。由于种种原因,他们在创造财富、就业竞争方面缺乏能力,在经济收入、社会地位、权益保护等方面得不到社会应有的保障。这个群体主要由残疾人、下岗失业人员、城镇贫困人群、农民工等组成。关注弱势群体是公安工作一项重要任务,也是实现社会治安综合治理的重要方面,关注弱势群体是目前公安工作中应当重视的问题。  相似文献

Abstract

Germany’s family policy responded to the European Union’s Barcelona targets by expanding publicly funded childcare, especially for children under the age of three, throughout the country. While overall nearly 33 per cent of all children in that age group had access to public childcare by 2015, there is still a large difference between the situation in the eastern and the western part of the country. This paper documents and explains this development of two persistently different childcare regimes in the two parts of the country. It shows that supply factors such as local administrative capacity and resources interact with demand factors such as parental need and demands for public childcare to produce the divergent development. It then discusses the conceptual challenges involved in engaging in this type of subnationally comparative analysis.  相似文献

强镇扩权的核心内容是通过放权赋予试点镇与县级政府相同的经济社会管理权限,但从其权力下放过程来看,县镇之间的权力配置和运作与现实需要、制度文本之间均存在着偏差。引发权力下放中县镇权力配置、运行偏差的原因不仅有放权的法律限度、更有其利益动机及其所契入的地方治理权力架构等。优化强镇扩权背景下县镇两级权力配置及其运行,是一项系统工程,应以完善的分权制度安排为主要手段,以必要的监督约束机制为补充,改善包括分权逻辑、放权原则、考核体制机制在内的整体性制度设计。  相似文献

近十年内我国新型毒品滥用问题的总体变化趋势   总被引:7,自引:0,他引:7  
近年来,我国毒品滥用的种类发生了很大变化。在海洛因大量滥用的同时,冰毒、摇头丸、氯胺酮(俗称K粉)等新型毒品从沿海地区迅速向全国蔓延,大有取代传统毒品海洛因成为吸毒者最主要消费品之势。为引起广泛关注,揭开隐蔽的面纱,文章就滥用新型毒品的人数、吸食群体的年龄结构、新型毒品的种类及吸食场所等方面论述了我国近10年(2001-2010年)来新型毒品变化的总体趋势,并针对这些问题提出了预防、控制、打击等相关对策建议。  相似文献

This article investigates the relationship between universities and academic spin-offs, with special emphasis on the antecedent conditions of, and the nature of the linkages that the spin-offs form, as well as the means for sustaining them. The present research uses an instrumental case study approach, and is also an instance of a collective case study as four companies of various size and activities have been studied together. The preliminary results indicate that the network relations are characterized by a small number of strong ties to universities, with a high degree of trust and informality. Although fruitful for the transfer of complex knowledge, the strength of the ties also make them difficult to substitute, which may lead to problems as the spin-offs are highly dependent on continued basic research support. This may in turn lead to implications for policy at university, as well as higher levels.  相似文献
