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.     

Produktdesign und Semi-Statische Absicherung von Turbo-Zertifikaten

Zusammenfassung  Turbo-Zertifikate geh?ren derzeit zu den beliebtesten strukturierten Produkten für Privatanleger. Sie lassen sich als Spezialformen von Barrier-Optionen auffassen. In Bezug auf das Produktdesign ist das Verh?ltnis von Kursschranke und Basispreis von Bedeutung. Unter Ausnutzung der Put-Call-Symmetrie wird gezeigt, dass eine geeignete Wahl der Ausstattungsmerkmale dem Emittenten eine semi-statische überabsicherung in Standard-Optionen erm?glicht, die bezüglich einer ganzen Modellklasse gültig ist. Im Gegensatz zu der in der Praxis g?ngigen Preisstellung kann eine Absicherung der Zahlungsverpflichtungen im Allgemeinen nicht unabh?ngig von der Volatilit?t erfolgen.

Product design and semi-static hedging of turbo-certificates

Summary  Turbo-Certificates are one of the most popular structured equity products for private investors in Germany. They can be regarded as special forms of barrier options. For the design of these products, the relation between the barrier level and the strike price is especially important. By using the put-call-symmetry, we show that by a certain choice of these parameters, the issuer is able to obtain an almost static (super-) hedge in standard option contracts which is valid for a general class of models. It turns out that in contrast to the pricing rule which is often used in practice, the issuer can neither hedge a single certificate nor a portfolio of certificates independent of the volatility.

     

供应链绩效评价指标体系与评价方法研究

供应链管理(SCM)与现行企业模式有较大区别,其绩效评价指标体系的建立与评价方法也就有其特殊性,目前这方面的研究还略显不足。本文在综合分析现有的SCM评价指标体系的基础上,初步建立了一套适合我国SCM绩效评价的指标体系。同时,给出了SCM绩效评价的多级动态模糊综合评价方法。

在分析了聚合物驱提高采收率技术在实际应用中的局限性基础上,提出了采用就地起泡形成泡沫的泡沫增强聚合物体系以减小聚合物沿大通道窜流的问题。为了有效确定该体系的配方,实验中采用了均匀设计实验方法安排实验,并运用DPS数据处理软件对实验数据进行了二次多项式逐步回归处理,找出了影响该体系性能的主要因素。     

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”。

An access network design problem with end-to-end QoS constraints

In this paper, we present an access network design problem with end-to-end quality of service (QoS) requirement. The problem can be conceptualized as a two-level hierarchical location-allocation problem on the tree topology with nonlinear side constraints. The objective function of the nonlinear mixed integer programming model minimizes the total cost of switch and fiber cable, while satisfying demand within the prescribed level of QoS. By exploiting the inherent structure of the nonlinear QoS constraints, we develop linearization techniques for finding an optimal solution. Also, we devise an effective exact optimal algorithm within the context of disjunctive constraint generation. We present promising computational results that demonstrate the effectiveness of the proposed solution procedure.     

Policy instrument affordances: a framework for analysis

The present study uses the concept of technological efficacy derived from ecological psychology and design studies to offer an alternative way of analyzing how policy instruments affect change. Reasoning from this, the paper outlines a framework for analyzing policy instruments in terms of their affordances. We define affordances as the means through which an instrument exerts influence on its intended target audience. Using this approach, we contend that policy instruments may be analyzed as interfaces that organize social relations and create structures of opportunity and/or restrict possibilities for action. We argue that explicating the pathways through which instruments afford or constrain action is a central task for policy analysis. Our proposed framework of analysis builds on the idea that instruments yield effects by facilitating action and learning. We further contend that the actions that an instrument can facilitate or inhibit are determined by specific affordance modalities of the instrument in conjunction with contingencies of the actor and the policy environment. Examples from research policy are used to illustrate some of these effects.
