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.     

基于情感体验的交互式包装设计与评价

包装不仅是商品的载体,也是品牌信息和情感体验的载体,是商品与消费者之间的信息沟通桥梁及商品体验营销的实现手段。以某护肤品包装设计为例,阐述了基于情感体验的本能层、行为层、反思层上的具体设计实践。同时,选取情感互动性、方便性、功能性、效率性、识别性5个评价指标,使用模糊综合评判法构建包装设计评价模型,对两个设计方案进行评价。方案一的评价结果为“良”,方案二的评价结果为“优”。

美国早期融合教育师资在线培养经验及启示

“办好公平而有质量的教育”是我国当前教育发展的主题,融合教育作为沟通普通教育和特殊教育的桥梁,是新时期 基础教育扩优提质计划的重要组成部分,亦是确保学前教育普及普惠的应有之义,其发展的关键在于培养高质量的融合 教育师资。通过对美国西南地区某研究型公立大学开发的一套早期融合教育师资在线培养课程进行解读,进而探究我国 学前融合教育教师培养路径。首先,从教学形式、教育对象和课程目标三方面分析该在线培养课程与同类型的线下课程 之间的差异：其次,总结该早期融合教育师资在线培养课程的特点;最后,结合该早期融合教育师资在线培养课程建设案 例,从教育对象、教育过程、课程评价和社会影响四方面,就创新我国学前融合教育人才培养方式的问题形成相应启示与 建议。     

健全粮食安全利益保障体系的机制设计与政策建议

发挥经济激励对国家粮食安全的保障作用至关重要。经过多年来的实践探索,我国基本建立起多维立体的涉粮激励政策体系,形成了稳定粮农收入、优化营商环境、调动产区积极性和保障消费者可得性的政策框架,但仍存在种粮农民利润空间压缩、粮油加工业后劲潜力不足、粮食主产区高产穷县等问题。针对粮食安全利益保障水平较低背后成因,探索构建以实现“产得出、运得到、买得起”为目标、协调粮食产业链利益相关主体关系、充分释放经济效益在保障粮食安全中作用的机制,并提出健全粮食安全利益保障体系的对策建议:一是优化补贴政策,强化政策保本功能;二是加快发展农业社会化服务,实现经营增效;三是协调产业链主体关系;四是逐步健全主产区利益补偿机制;五是健全应急储备及市场调节机制。     

考虑组织成本的两阶段竞赛机制研究

在企业招聘实践中,招聘成本是企业管理者在制定招聘策略时所考虑的重要因素之一。为保证招聘效果并控制成本,企业管理者将选择不同成本的人才测评方法,分阶段地筛选应聘者,选择测评方法和确定各阶段应聘者人数成为企业管理者主要的决策问题。在此管理背景下,进行两阶段竞赛机制的研究,并将节约组织成本作为竞赛设计者目标的一部分。分别修改竞赛者总努力最大化和最高努力最大化这两个传统目标,得到两个修正后的优化目标。当竞赛者能力分布函数为幂函数时,通过模型分析和数值模拟。研究结果表明,两个优化目标下的最优竞赛机制具有共同性质,即针对确定的奖励选择竞赛筛选方法时,单位组织成本不能过大;在确定筛选方法后,如果奖励与单位组织成本的比值过小,或低能力者占竞赛者的大部分,那么应仅允许两名竞赛者进入复试。另外,对于以竞赛者最高努力最大化为目标的竞赛,如果高能力者相对较多时,第二阶段的最优竞赛人数也为2。

Decision settings analysis – a tool for analysis and design of human activity systems

The paper describes a methodology to be used for analysis and design of human activity systems. The methodology is based on an analysis of the decision settings whereas most other decision analysis methodologies are analysing the process. The decision concept is analysed and discussed. A distinction between programmed and programmable as well as non-programmed and non-programmable decisions is proposed. A classification of different information types for decision making is presented. A methodology based on a systemic and systematic analysis of the information requirements of an organization is proposed. This methodology also indicates organizational discrepancies and information imbalances. The methodology focuses the settings of the decisions on all levels of organizations. The methodology can be regarded as a dynamic, learning system. The author proposes further research on the individuals decision making abilities.     

Designing and integrating composite networks for monitoring multivariate gaussian pollution fields

Networks of ambient monitoring stations are used to monitor environmental pollution fields such as those for acid rain and air pollution. Such stations provide regular measurements of pollutant concentrations. The networks are established for a variety of purposes at various times so often several stations measuring different subsets of pollutant concentrations can be found in compact geographical regions. The problem of statistically combining these disparate information sources into a single 'network' then arises. Capitalizing on the efficiencies so achieved can then lead to the secondary problem of extending this network. The subject of this paper is a set of 31 air pollution monitoring stations in southern Ontario. Each of these regularly measures a particular subset of ionic sulphate, sulphite, nitrite and ozone. However, this subset varies from station to station. For example only two stations measure all four. Some measure just one. We describe a Bayesian framework for integrating the measurements of these stations to yield a spatial predictive distribution for unmonitored sites and unmeasured concentrations at existing stations. Furthermore we show how this network can be extended by using an entropy maximization criterion. The methods assume that the multivariate response field being measured has a joint Gaussian distribution conditional on its mean and covariance function. A conjugate prior is used for these parameters, some of its hyperparameters being fitted empirically.
