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.

     

应用型本科艺术设计人才培养“底线”与“顶线”的思考 ——以徐州工程学院为例

在我国积极推进高校“应用型”本科院校改革与建设的过程中,科学发展观是决定其成败的关键问题。而建立科学发展 观的前提是理清高校日常教学工作与教育内容所依据和参考的标准——“底线”与“顶线”问题。而在以徐州工程学院艺术设 计专业为代表的“应用型”学科的发展过程中,由于院校间的差异,存在着制度和内容各不相同的“底线”与“顶线”问题。为此, 在应用型本科艺术设计专业办学过程中理清两条线各自的定位与标准,对于科学推进应用型高校本科层次艺术设计专业的教 育教学改革,提升应用型艺术设计人才培养水平有着十分重要的作用。     

泡沫增强聚合物体系配方研究

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”。

价差期权的合约设计、定价与实证分析——基于冶炼价差期权的应用

研究价差期权的合约设计及其定价方法,对于提高我国各类经济实体的风险管理水平以及我国衍生品市场的未来发展具有重要意义.依据我国螺纹钢与铁矿石等冶炼价差的统计特征,借鉴国外价差期权定价方法,对冶炼价差期权的实际价值、理论价格进行了测算,结果表明:在冶炼价差期权中,螺纹钢与铁矿石的价差、钢坯与铁矿石的价差的绝对变化幅度更大,对应的价差期权的实际价值更大,对应的套保需求会更大;与铁矿石有关的价差(螺纹钢与铁矿石、钢坯与铁矿石)期权的套保效果更好.建议先行推出螺纹钢与铁矿石、钢坯与铁矿石这两种冶炼价差期权.     

Lena Finkle’s magic arc: hybrid influences in the Russian American graphic novel

ABSTRACT

The article examines Anya Ulinich’s graphic narrative Lena Finkle’s Magic Barrel and the novel’s use of visual culture from both the author’s Russian and US American backgrounds. The article interrogates the use of history and timelines, Russian art history and Russian art education in Ulinich’s text. It also analyzes other literary constructs that influenced Ulinich’s novel: US American comics/graphic novels and their use of stereotype, and novels by Russian-speaking Jewish American writers, with their thematized Jewishness.     

Multiphase experiments in practice: A look back

Multiphase experiments are introduced and an overview of their design and analysis as it is currently practised is given via an account of their development since 1955 and a literature survey. Methods that are available for designing and analysing them are outlined, with an emphasis on making explicit the role of the model in their design. The availability of software and its use is described in detail. Overall, while multiphase designs have been applied in areas such as plant breeding, plant pathology, greenhouse experimentation, product storage, gene expression studies, and sensory evaluation, their deployment has been limited.     

A Bayesian sequential design with binary outcome

Several researchers have proposed solutions to control type I error rate in sequential designs. The use of Bayesian sequential design becomes more common; however, these designs are subject to inflation of the type I error rate. We propose a Bayesian sequential design for binary outcome using an alpha‐spending function to control the overall type I error rate. Algorithms are presented for calculating critical values and power for the proposed designs. We also propose a new stopping rule for futility. Sensitivity analysis is implemented for assessing the effects of varying the parameters of the prior distribution and maximum total sample size on critical values. Alpha‐spending functions are compared using power and actual sample size through simulations. Further simulations show that, when total sample size is fixed, the proposed design has greater power than the traditional Bayesian sequential design, which sets equal stopping bounds at all interim analyses. We also find that the proposed design with the new stopping for futility rule results in greater power and can stop earlier with a smaller actual sample size, compared with the traditional stopping rule for futility when all other conditions are held constant. Finally, we apply the proposed method to a real data set and compare the results with traditional designs.
