生态位在企业人才安全内涵探讨的应用

在探讨人才安全的涵义时,通过引入生态位原理,系统分析了企业人才安全的运行机理和基本内涵,指出企业人才安全就是企业人才系统与管理系统相匹配,从而达到企业和人才都能发展的动态平衡状态。并依据人才安全的运行机理,设计出切实可行的企业人才安全评价指标体系,然后运用模糊综合评判方法对实例进行验证,得出对企业人才安全的评价。     

黑龙江省煤炭城市土地利用综合效益时空变异分析

定量分析和评价煤炭城市土地利用综合效益并确定其空间分布,为煤炭城市集约合理利用土地提供科学依据。以黑龙江省煤炭城市为例,以影响城市土地利用综合效益的土地投入效益、土地利用效益、土地产出效益和土地生态效益为要素层,构建黑龙江省煤炭城市土地利用综合效益评价指标体系,运用最优组合赋权法确定指标权重,采取多目标综合评价法,对2002—2007年土地利用综合效益进行定量分析。结果表明,黑龙江省煤炭城市6年间土地利用综合效益呈上升趋势。土地投入效益、土地利用效益、土地产出效益和土地生态效益对土地利用综合效益影响存在一定的差异,土地利用协调度呈现先上升后下降的趋势,土地利用协调度的下降将成为土地利用综合效益进一步增长的障碍。

消费者对可追溯牛肉的认知及其影响因素分析——基于结构方程模型

利用针对北京市城区消费者的402份调查问卷数据,运用结构方程模型,分析了消费者对可追溯牛肉的认知及其影响因素。结果显示,消费者对可追溯牛肉的认知水平较低,但消费者在信息强化后对可追溯牛肉安全性的评价较高;信息搜集和经济文化因素显著影响消费者对可追溯牛肉的认知水平,风险感知、牛肉重要性和经济文化因素显著影响消费者对可追溯牛肉的认知内容,但认知水平并不显著影响认知内容。最后提出相关对策建议。     

Identifying significant characteristics of organic milk consumers: a CART analysis of an artefactual field experiment

The organic dairy category is one of the fastest growing categories of organic foods in the US. Organic milk consumers generally cite perceived health benefits and lower risk of food contamination, as well as perceived superior quality and environmental sustainability of organic farming methods, as the major motivations for preference of organic over conventional milk. While the attributes of organic milk that are valued by consumers are fairly well-known, more ambiguity exists regarding the demographic characteristics of the typical organic milk consumer. This research makes use of experimental data from 148 adult participants and use a Classification and Regression Tree (CART) analysis, a nonparametric modelling approach, to identify how Willingness-to-Pay (WTP) for organic milk varies with the demographic profile of experiment participants. The study finds that perceived taste of organic milk, concern for the risk of consuming conventional milk, being a primary shopper, and the quantity of milk consumed are the major factors that separate experiment participants into groups with high and low WTP for organic milk.     

Compulsory schooling laws and school crime

Extensive literature demonstrates that compulsory schooling laws improve educational attainment, well-being, civic involvement, and labour market outcomes. However, at-risk youth incapacitated to schools may impact the learning environment and school safety. The purpose of this article is to study whether raising the minimum dropout age (MDA) requirement above 16 increases crime committed within US public high schools. A difference-in-difference estimation exploits changes in state-level MDA laws over time and indicates that schools in states that raise their MDA requirement to 18 incur more overall crime relative to schools in states that do not, while no effect on overall crime is identified when the MDA requirement is raised to 17. Furthermore, these effects persist for 4 years after passage and more intensely in metropolitan areas. Coupling this research with existing literature suggests that when the MDA requirement is raised to 18, only a small portion of the observed reduction in juvenile crime is displaced to schools. Analysis by category of crime reveals schools incur more physical attacks, no change in illegal drug and property crimes, and fewer violent crimes in states that raise their MDA requirement to 18, while illegal drug crimes increase in states that raise their MDA requirement to 17.     

Why Any Seatbelt Mandate is an Infinitely Iterated Prisoner’s Dilemma: A Health Economics Perspective

Abstract

Among the most controversial of public health measures are those that restrict people’s freedom of choice presumably for the purpose of protecting their own health and safety. Mandatory use of automobile seatbelts can inspire allusions to the “tyranny of health” and the ‘health police.” This study revisits state seatbelt legislation, which is in force in all but one state of the USA. In modeling seatbelt mandates as indefinitely repeated Prisoner’s Dilemma (PD) games, the study qualifies and overcomes the limitations of conventional interest group and expressive voting theories. It indicates why and how utility-maximizing players, particularly carmakers, insurance companies, consumer advocates and regulators, may choose to cooperate, even in instances where mutual defection would bring each of them higher payoffs. The study suggests why state seatbelt mandates endure, despite ongoing concerns that they undermine individual autonomy or that their social costs outweigh the benefits of law-enforcement. The evolution and mediating effects of reputation and reciprocity in otherwise highly contestable healthcare decisions are consequently explored. Finally, the study identifies the implications of indefinitely repeated games on the continuing nature of strategic relationships and for mitigating conflict over traffic safety regulation, regardless of time and place.
