高校社团对基层团组织的功能替代

在新时期里,高校基层团组织的传统工作模式受到了前所未有的挑战,其功能也呈现出明显弱化的迹象;而学生社团则在高校中蓬勃发展,甚至对团组织起到了某种程度上的“功能替代”作用。一种功能互补的趋势正在悄然形成中。     

在华韩国跨国公司内部贸易研究

随着中韩贸易的快速发展.韩固对华投资也大幅增长.韩国在华跨国公司内部贸易发挥着日重重要的作用.韩国跨国公司将交易从外部市场转移到内部市场,产生了诸如垄断先进技术,损害我国经济利益以及降低引进资本投资的关联效应等诸多问题.对此,应从控制跨国公司转移价格的实施、利用竞争机制合理有效地诱导跨国公司技术转移、规范投资领域、加强监管等方面对韩国跨国公司的内部贸易采取相应对策.

农村外出劳动力回流迁移的影响因素和回流效应

文章分析农村外出劳动力回流迁移的影响因素.农村外出劳动力在城市就业、经济收入和社会保障的排斥影响他们的回流,同时回流迁移也受到家庭生活、家庭劳动力状况、家庭农业活动和农地状况等因素的影响.外出劳动力的回流迁移是“被动回流”和“主动回流”相结合的过程、是个体决策和家庭决策的综合过程.文章提出劳动力回流迁移具有“回流效应”,回流带来人力资本的补偿、促进流出地非农经济的发展和带来创业的增长.劳动力回流作为城镇化过程中内生的逆迁移流,构成乡城迁移和劳动力市场平衡的补充机制,与乡城迁移一起促进城镇化和城乡平衡发展.文章提出在城镇化过程中需要支持“迁移效应”和“回流效应”机制共同发挥作用.     

A balancing act in urban social-ecology: human appreciation,ponds and dragonflies

Green spaces in cities provide cultural ecosystems services (CES) such as nature connection, wildlife interaction and aesthetic appreciation which can improve aspects of human well-being. Recognising these benefits, researchers are now examining the complex relationship between humans and nature in urban social-ecology. Most studies investigate people’s appreciation and valuation of different green space features and their contribution to urban biodiversity. Recommendations arising from such studies are best practices to achieve a balance between landscape aesthetic and ecological objectives, but many knowledge gaps still exist. In a social-ecological project in Greater London, appreciation of ponds and dragonflies in urban green spaces, and the environmental factors determining dragonfly diversity were investigated. We found ponds and their appearance were valued by people as enhancing their green space experience. The preference for wild-looking ponds was moderate. Dragonflies were enjoyed for their colour and high visibility, especially by those who had basic dragonfly knowledge. Species richness of dragonflies was positively associated with habitat heterogeneity in and around a pond. However, people were unable to relate a heterogeneous pond to more dragonfly species. For the first time, some factors that influence the human appreciation-ponds-dragonflies (HPD) relationship in an urban context are revealed. To fully realise the CES potential of ponds and dragonflies in Greater London, a HPD framework is proposed. The framework underpins strategies that foster cultural sustainability for ponds and dragonfly conservation.     

Parameter estimation of the censored δ-shock model on uniform interval

The censored δ-shock model is a special kind of shock model and it has very important research values in the reliability theory. In this paper, we discuss the parameter estimation of the censored δ-shock model when the inter-arrival times between two successive shocks follows uniform distribution on [a, b]. With the maximum likelihood estimation, we obtain the parameter estimator and expectation of estimator and lifetime of the model. By numerical simulation, we get the empirical result on the estimator of δ and the relationship between δ and other parameters.     

Single-stage sampling procedure of the t best populations under heteroscedasticity

Given k( ? 3) independent normal populations with unknown means and unknown and unequal variances, a single-stage sampling procedure to select the best t out of k populations is proposed and the procedure is completely independent of the unknown means and the unknown variances. For various combinations of k and probability requirement, tables of procedure parameters are provided for practitioners.
