论英语专业教学中学生非智力因素的培养

非智力因素是保证成功进行各种活动的必要心理条件。在英语专业课程学习中,学生的非智力因素能够直接转化为学习动机,把学习当作自觉行为。教师应注重学生兴趣、情感、意志、性格等非智力因素的培养,讲究教学艺术,建立宽松互动的学习环境,使学生的非智力因素在学习中起到重要作用。     

俄语学习过程中的干扰问题研究

干扰是俄语学习及进一步提高俄语水平的重要制约因素。俄语学习者已获得的知识、技能、学习方法和态度会对学习俄语产生消极影响。干扰产生的原因主要有语间干扰、语内干扰和文化干扰,学习者要区别对待,有针对性地采取有效措施消除干扰。

知识缺失还是知识自负？知识水平对公众食品安全信心的影响研究

通过对中国10个城市成年受访者的调查,发现公众对当前食品安全问题的感知风险水平较高,反映其对食品安全形势较担忧,且对政府食品安全管理部门存在信任危机。不过公众的感知控制力较高,普遍认为自己有保障自身食品安全的能力,因此在日常的食品消费中仍然有较高的信心。研究证实中国公众在食品安全的知识层面存在着知识自负现象,公众自我评估的主观知识水平显著高于实际拥有的客观知识水平,且真正对公众食品安全信心产生影响的是公众的主观知识水平。这说明传统缺失模型所倡导的以科普、辟谣为主要形式的致力于教育公众、提升公众客观知识水平的行动能够取得的效果可能非常有限;而公众的主观知识水平和感知控制力的提升能有效提振公众的食品安全信心。     

Coherent decision analysis with inseparable probabilities and utilities

This article explores the extent to which a decision maker's probabilities can be measured separately from his/her utilities by observing his/her acceptance of small monetary gambles. Only a partial separation is achieved: the acceptable gambles are partitioned into a set of belief gambles, which reveals probabilities distorted by marginal utilities for money, and a set of preference gambles, which reveals utilities reciprocally distorted by marginal utilities for money. However, the information in these gambles still enables us to solve the decision maker's problem: his/her utility-maximizing decision is the one that avoids arbitrage (i.e., incoherence or Dutch books).     

A Population Approach to Analysis of Variance Models

Several authors have contributed to what can now be considered a rather complete theory for analysis of variance in cases with orthogonal factors. By using this theory on an assumed basic reference population, the orthogonality concept gives a natural definition of independence between factors in the population. By looking upon the treated units in designed experiments as a formal sample from a future population about which we want to make inference, a natural parametrization of expectations and variances connected to such experiments arises. This approach seems to throw light upon several controversial questions in the theory of mixed models. Also, it gives a framework for discussing the choice of conditioning in models

The Big Five personality factors and team performance: implications for selecting successful product design teams

In the pursuit of faster product development, product design teams are a growing phenomenon in many organizations. In order to be successful, these teams must be composed of people who work well together. However, despite the benefit of selecting the optimal combination of team members, this topic has received little attention. Personality has been identified as a potentially helpful selection variable in the determination of optimal team composition. This study examines the relationships between the ‘Big Five’ personality factors (Conscientiousness, Extraversion, Neuroticism, Agreeableness, and Openness to Experience) and objective team performance for three-member product design teams. In addition to this, the potential incremental contribution of personality to the variance in team performance over that accounted for by established selection measures such as general cognitive ability was investigated. In the short duration of the study, it became apparent that some teams were capable of success, and some were not. Successful teams were characterized by higher levels of general cognitive ability, higher extraversion, higher agreeableness, and lower neuroticism than their unsuccessful counterparts. In successful teams, the heterogeneity of conscientiousness was negatively related to increments in product performance. Implications for the selection of product design teams and future directions for research are discussed.     

制造企业服务业务扩展及其认知因素研究

制造企业的竞争越来越激烈,几乎所有的企业都要面对快速反应多变市场和应对价格压力的要求,面对越来越小的产品利润空间和越来越复杂的客户需求,本文从对工业服务管理文献分析和制造企业的调查研究入手,揭示了制造企业从纯粹的产品生产者向客户支持方案提供者发展的转移趋势.通过对瑞士和德国30多家机器和设备制造企业进行的调查研究,说明了服务业务对制造企业在开发财务、营销和战略机会上的重要作用,并对转移过程中服务业务的扩展过程进行了总结.结合具体企业实践,本文对制约制造企业扩展服务业务中在管理动机上的认知因素进行了分析和研究.结合中国加入WTO后,中国制造企业将全面融入国际竞争的背景,本文期望对中国制造企业的发展和竞争地位的提高提供理论和实践上的指导.     

论概率安全评价中的组织风险因素

核电站组织风险已经成为核电站安全运行重要的影响因素,在概率安全评价中考虑组织风险因素是核电安全研究的重要课题。文章在建立组织风险因素与PSA之间转换的概念框架的基础上,对组织风险因素进行分类。分类后的组织风险因素受人员行为形成因子的影响,其影响在人因可靠性分析中进行分析。计算和评估这些人员行为形成因子对于事故后操纵员的影响可以计算组织因素对核电站安全的影响。
