略论保险利益对道德危险的防范作用

保险利益是保险法中防范道德危险最直接、最有效的法律制度,不过其作用的发挥受到该制度具体内容的影响。要以对道德危险的防范为中心,探讨保险利益内涵的法律界定方式、该原则的效力范围以及人身保险中保险利益等颇具争议性的问题。通过对比国外立法经验和考查我国现行法律规定的不足,为我国保险法的完善提出建议。     

产品生命周期的研究

产品生命周期是指一代产品进入市场后需求存续变化的周期,而不是指需求量、销量波动变化的周期。我们应当研究细分市场的产品生命周期,根据市场某种特性质变的界面来划分产品生命周期的阶段,才更具有营销意义。现行流行的划分产品周期阶段的四种方法。缺乏理论依据,在应用中有较大的随意性。为此,提出了综合判断法,根据多个判据的组合,定位了产品生命周期阶段之间的界面,并提出了对应的营销策略。     

Hong Kong parents' perceptions of the transference of food preparation skills

Food preparation skills among young adults are associated with healthy food choices, better diets and a greater likelihood of an independent, healthy adult life. This study conducted in Hong Kong aimed to investigate parents' perceptions of cooking skills; to explore the transference of cooking skills in the home setting; to identify parents' expectations regarding the transference of cooking skills; and to inform the development of educational initiatives for developing healthy eating habits. A questionnaire survey was conducted to collect information of the subjects' cooking experience, attitudes about cooking skills, cooking habits at home, family meal habits, transference of cooking culture in the family and the factors influencing the choice of ingredients and cooking. It was administered to 1009 Hong Kong parents (of students aged between 11 and 18, studying in 15 secondary schools). The collected data were analysed using the Statistical Package for the Social Sciences (version 12.0, SPSS, Inc., Chicago, IL, USA) and cross‐tabulation analyses were used to compare the responses of the parents by gender, employment status and income. The results show that parents valued cooking as important life skills for both boys and girls. Parents generally perceived their cooking skills either good (41.9%) or mediocre (54.5%), yet children are rarely taught these skills in the home. Family meals prepared primarily with fresh ingredients are still an important part of the daily routine, and mothers are dominating the roles in food choice decision, cooking and buying the ingredients for family meals. Mothers and schools are expected to be the major channel to teach children cooking skills. Findings suggest that parents are well‐disposed towards providing food and nutrition education at home, but need more support (50% reported that home should be a primary support for learning cooking skills; 36% indicated that the school should have a responsibility to teach children to cook starting in elementary school). Schools may do well to collaborate with families in food literacy education initiatives. Developing individuals' cooking skills paves the way for long‐term health benefits and the well‐being of the local population.     

基于核电发展的铀资源供需趋势及对策分析

在世界核电复苏以及我国积极发展核电的背景下,铀资源供需平衡已经成为国内外关注的焦点。而我国铀资源供需前景不容乐观,铀供给的安全将是我国核电可持续发展的制约因素之一。根据对世界铀资源供需现状及前景分析,应加强我国铀资源供给能力的对策,努力完善我国闭式核燃料循环技术和充分利用国外铀市场。     

企业核心能力生命周期的特性

核心能力在企业发展的过程中是动态发展的,并且存在一个从培育、形成、提高到再生或者衰退的生命周期过程。核心能力是企业取得长期竞争优势的源泉。因此,企业决策者在企业发展过程中必须对核心能力生命周期的各个阶段的特性予以清楚地了解,以便企业根据特性通过具体的运作来实现核心能力的维护和提升,从而达到核心能力持续成长的目的。

经济周期定期方法与研究进展

经济波动一直是宏观经济分析与预测中的经典问题,而经济周期拐点的及时识别对政府前瞻性经济政策的制定和企业投资经营战略的调整具有重要意义。鉴于我国目前尚没有权威机构对经济周期进行实时监测和发布,因而在划分经济周期和拐点识别时,往往局限于一种方法,不同方法有效性的比较缺乏一个基准参考。文章对国内外研究经济周期及其周期拐点定期的方法进行梳理和分析,依据经济周期定期方法的研究脉络,对主流的方法进行评述,并对我国经济周期定期进行展望,希望能在分析中国宏观经济波动特征和经济走势预测方面提供一些方法论参考和借鉴。     

中国上市银行信贷行为的周期性研究

文章基于中国上市银行1998-2013年的数据,采用固定效应模型,对16家中国上市银行信贷行为的周期性进行了研究。研究表明,中国上市银行的信贷行为表现为阶段顺周期性和阶段逆周期性;银行规模对其周期性也有较大影响,规模较小银行或同一银行在规模较小阶段其信贷的逆周期性更显著。由于当前我国政府对宏观经济及银行行为的干预程度较大,银行监管当局所制定监管政策的针对性及有效性将受到很大削弱,因此文章建议政府的宏观经济调控政策与银行的监管政策必须相互协调,这是未来防范经济危机与金融危机,促进中国经济健康持续发展,保持中国金融系统稳健经营的必然选择。     

产业集群的人才集聚机制研究

在产业集群的经济增长作用日益突出的今天,集群内的人才集聚现象也越来越受到学者们的关注。文章基于成本收益理论以及人口迁移中的“推－拉理论”等,对产业集群作用下的人才集聚现象进行了分析,并进一步阐述了产业集群内的产业链与人才链的耦合效应以及产业集群生命周期阶段人才集聚的演化过程,得出由于在产业集群的外部经济效应和知识溢出效应等自身诸多特征的作用下人才集聚得以实现,并且产业集群生命周期的不同阶段人才集聚对经济的贡献是有所差异的基本结论。这一结论将会给地方政府在制定区域人才开发政策时提供不同的视角,以便有针对性地遵循产业生命周期阶段来进行人才结构的调整与升级,保证人才集聚的持续性与区域经济的可持续发展。
