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.     

西部地区社会保障体系的模式设计与理论创新

西部地区的经济发展需要社会保障制度为其构筑一道“安全网”。回顾西部地区社会保障的发展历史,从社会保障中几个重要指标出发对西部地区社会保障制度作出绩效评估、分析其原因,并且提出西部地区建立覆盖城乡居民的社会保障体系的基本框架、实现路径、步骤与措施。     

我国新型农村养老保险制度的SWOT分析

文章从新农保的“新”字入题,试图借鉴管理学SWOT研究分析方法,从我国当前新型农村养老保险制度发展所面临的发展机遇、环境挑战、自身优势以及存在的问题四个方面内容展开探讨,并在此基础之上,从优化制度运行环境与制度自身完善两个方面对如何推动“新农保”制度建设提出了对策和建议。     

食品安全风险行政规制的信息工具选择

信息工具选择和运用直接关系到食品安全风险行政规制的效果.食品安全风险行政规制中信息工具的应用涵盖了信息收集渠道、信息公示平台、安全信息管理以及事后监管机制等.同时,食品安全风险行政规制信息工具存在具有信息来源与收集路径的单一性、信息流通的内部性、信息控制与公布的主体的多重性和相对人权利救济的滞后性等缺陷.为此,需要有针对性地拓展网络信息的收集路径;严格信息流通的责任制度;加强信息工具与其他工具的组合运用;完善风险信息发布的相对人救济机制,并引入预防性诉讼和公益诉讼制度.     

“异域”之异表现在哪里?——解析萨伏伊《异域》

萨伏伊在《异域》里把美国南方视为一个不同于美国北方的“异域”,从系统力量之异、种族关系之异和种族心理之异的角度展现“异域”之异,揭露黑人的悲剧人生和白人种族主义制度的非人性和非理性.政治之异、司法之异和大众媒体之异显示了美国社会系统力量的冲突和内耗,抨击了不合理社会制度的反人类性和反文明性.种族情结、种族疏离和信用危机引发的种族关系之异严重威胁着社会稳定和人身安全,恶化了美国的种族关系;身份焦虑、歧视焦虑和越界焦虑通常会深化美国社会的种族心理之异,加剧黑人的双重意识危机,妨碍美国多元化社会的建立和发展.     

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.     

农村养老服务供给侧改革的研究理路与实现方式

农村养老服务是国家和社会为了满足农村老年人的基本生活需求而为其提供的经济供养、生活照料、医疗卫生护理及精神慰藉等服务的总称.伴随人口老龄化进程的加快,农村养老服务需求日益增加,并因农村老年群体分异而出现了需求分化现象,但从农村养老服务供给结构的布局上看,无论是供给内容、供给主体还是供给模式都不能有效满足农村老年人的养老需求,存在着供需失衡的结构性困境.为推进农村养老服务供给侧改革,可从坚持政府的核心供给地位、引导社会组织参与提供养老服务、激发市场供给的活力和鼓励家庭养老的优先供给四个方面做文章.
