跨界行为对创造力影响的跨层次双刃剑效应

本文从资源的视角,在团队和个体两个层面探究了跨界行为分别对团队创造力和个体创造力的影响以及中介机制和边界条件。采用多阶段-多来源的方式收集数据。研究结果表明在团队层面上,团队跨界行为会提高团队创造力,但在个体层面上,员工跨界行为通过增加员工的角色压力对个体创造力产生不利影响。角色宽度自我效能感调节了上述关系,相比于角色宽度自我效能感较高的员工,角色宽度自我效能感较低的员工实施了跨界行为后更容易产生角色压力,对个体创造力的负向影响更强。     

Item Selection With Collaborative Filtering in On-The-Fly Multistage Adaptive Testing

An important design feature in the implementation of both computerized adaptive testing and multistage adaptive testing is the use of an appropriate method for item selection. The item selection method is expected to select the most optimal items depending on the examinees’ ability level while considering other design features (e.g., item exposure and item bank utilization). This study introduced collaborative filtering (CF) as a new method for item selection in the on-the-fly assembled multistage adaptive testing framework. The user-based CF (UBCF) and item-based CF (IBCF) methods were compared to the maximum Fisher information method based on the accuracy of ability estimation, item exposure rates, and item bank utilization under different test conditions (e.g., item bank size, test length, and the sparseness of training data). The simulation results indicated that the UBCF method outperformed the traditional item selection methods regarding measurement accuracy. Also, the IBCF method showed the most superior performance in terms of item bank utilization. Limitations of the current study and the directions for future research are discussed.

The Measurement of Engagement and Burnout: A Two Sample Confirmatory Factor Analytic Approach

This study examines the factorial structure of a new instrument to measure engagement, the hypothesized `opposite' of burnout in a sample of university students (N=314) and employees (N=619). In addition, the factorial structure of the Maslach-Burnout Inventory-General Survey (MBI-GS) is assessed and the relationship between engagement and burnout is examined. Simultaneous confirmatory factor analyses in both samples confirmed the original three-factor structure of the MBI-GS (exhaustion, cynicism, and professional efficacy) as well as the hypothesized three-factor structure of engagement (vigor, dedication, and absorption). Contrary to expectations, a model with two higher-order factors – burnout and engagement – did not show a superior fit to the data. Instead, our analyses revealed an alternative model with two latent factors including: (1) exhaustion and cynicism (core of burnout); (2) all three engagement scales plus efficacy. Both latent factors are negatively related and share between 22% and 38% of their variances in both samples. Despite the fact that slightly different versions of the MBI-GS and the engagement questionnaire had to be used in both samples the results were remarkably similar across samples, which illustrates the robustness of our findings.     

A real‐world MCDA application: evaluating software

A real‐world multi‐criteria decision aid (MCDA) application on software evaluation is presented in this paper. The decision process concerned a big Italian company faced with the management of a call for tenders for a very important software acquisition. The decision aiding process is extensively presented and discussed, mainly as far as its products are concerned, i.e. –the problem situation; –the problem formulation; –the evaluation model; –the final recommendation. The results of the experience are discussed using the comments of the client of the study. Copyright © 2000 John Wiley & Sons, Ltd.     

The person response function as a tool in person-fit research

Item responses that do not fit an item response theory (IRT) model may cause the latent trait value to be inaccurately estimated. In the past two decades several statistics have been proposed that can be used to identify nonfitting item score patterns. These statistics all yieldscalar values. Here, the use of the person response function (PRF) for identifying nonfitting item score patterns was investigated. The PRF is afunction and can be used for diagnostic purposes. First, the PRF is defined in a class of IRT models that imply an invariant item ordering. Second, a person-fit method proposed by Trabin & Weiss (1983) is reformulated in a nonparametric IRT context assuming invariant item ordering, and statistical theory proposed by Rosenbaum (1987a) is adapted to test locally whether a PRF is nonincreasing. Third, a simulation study was conducted to compare the use of the PRF with the person-fit statistic ZU3. It is concluded that the PRF can be used as a diagnostic tool in person-fit research.The authors are grateful to Coen A. Bernaards for preparing the figures used in this article, and to Wilco H.M.

Re-Conceiving God and Humanity in Light of Today's Evolutionary-Ecological Consciousness

The anthropocentric orientation of traditional understandings of Christian faith and life, further accentuated by the existentialist terms in which theology was articulated in mid-century by Tillich and others, produced theologies no longer appropriate in today's world of evolutionary and ecological thinking about human existence and its embeddedness in the web of life on planet Earth. This problem can be addressed with the help of several new concepts that enable us to understand both humanity-in-the-world and God in ways in keeping with these present conceptions, thus providing a more intelligible and illuminating way of understanding Christian faith and life today.     

What laypeople think the Big Five trait labels mean

We asked what laypeople think the commonly used Big Five trait labels mean, and how well their beliefs match the content of standard Big Five scales. Study 1 established participants’ familiarity with the Big Five trait labels. In Studies 2 and 3, participants described persons high on the traits using a free response format. Responses were sorted into categories (facets), each of which earned a centrality index defined as the proportion of responses for the given trait that fell into that category. Studies 2 and 3 converged well. Comparisons with four standard Big Five inventories revealed substantial commonality but also notable areas of non-overlap consisting of content identified by laypeople that was not represented in the standard scales, as well as content in the standard scales that was not mentioned by laypeople.     

Efficient search under constraints and not working memory resources supports creative action emergence in a convergent motor task

Creative (original and functional) solutions to problems can be facilitated by guiding search behavior. According to cognitive models, when solving convergent tasks (tasks with few solutions), high available working memory (WM) resources and capacity can guide creative solution emergence via repeated (persistent) search within a solution subcategory. However, no clear associations have been found of WM capacity on creative outcomes when tasks require the individual to enact solutions in divergent doing tasks. This study further tested constraints on WM resources on search behavior and creative outcomes in a convergent doing task. Novices to combat sports were asked to repeatedly strike a target with the intent to achieve an individualized target force. In order to manipulate available WM resources, every ten strikes, participants were asked to recall and then retain a sequence of 5 digits (high load group: n = 21) or 2 digits (low load group: n = 21). The task constraints favored the functionality (or appropriateness) of a qualitatively distinct, non-obvious solution. Functionality was assessed using the force registered for each strike. Originality was assessed in terms of how infrequently actions occurred. Finally, search behavior was quantified based on changes in which limb was used and changes in which part of the limb was used from one strike to the next. There were no significant effects of WM load on creativity outcomes, solution search, or task success. Rather, task success was related to efficient search and creativity. Future research should focus on constraints (other than WM resources) that promote efficient search.
