Personality types and motivational characteristics of academics versus professionals in industry in the same occupational discipline

The present study suggests that individuals belonging to different job categories—academics versus professionals in industry—differ in personality types and in motivational characteristics even though they are of the same occupational discipline. Subjects were 49 academics and 45 professionals in industry of two disciplines: engineering and management sciences. Holland's 6 personality types and 18 motivational characteristics measured in terms of Vroom's expectancy theory of motivation were used as the discriminant variables. Results indicate that academics are discriminated from professionals in industry by scoring significantly higher on the Artistic type and significantly lower on the Enterprising type even when the discipline is controlled. The distinction between the two groups is much deeper when motivational factors are examined: Academics are motivated by the opportunity for scientific contribution, for autonomy, and for the high status attained in their job. By contrast, professionals in industry are highly motivated by the opportunity for exercising power.     

Expected performance at the human/computer interface as a function of user proficiency and system power

How do managers expect the proficiency of users and the power of the computers to determine overall performance? Five different models are proposed: (a) a matching model in which optimal performance is achieved when the power of the system is judged to be compatible with the proficiency of the user, (b) an averaging model in which expected performance is the average of the values of user proficiency and system power, (c) a multiplying model in which performance is the product of the values of user proficiency and system power, (d) a human/computer ratio model in which performance is determined by the ratio of system power over total effort, and (e) a computer/human ratio model in which performance is determined by the ratio of user proficiency over total effort. The applicability of these models was assessed by having managers and students of management predict performance in human/computer systems from information about the user's proficiency with computers and the power of the system. Participants rated 16 combinations of user proficiency and system power from a 4 × 4 factorial design. The pattern of ratings indicated that 51 per cent used a multiplying model and 25 percent used an averaging model; whereas, only 6 percent used the matching model and 4 percent used a ratio model. The remaining 14 percent did not follow any model clearly. Implications of these results were discussed for the design of the human/ computer interface, training and selection of users, and the cost-benefit tradeoffs for investment in user training versus equipment acquisition.     

Integrative bargaining in a competitive market

The behavioral decision theory literature was used to identify the determinants of negotiation success in an integrative bargaining, free-market exercise. This study provides a novel methodology for studying negotiation. Specifically, buyers and sellers were allowed to engage in negotiations with as many competitors as possible in a fixed time period. The results suggest that integrative bargaining behavior increases and the market converges toward a Nash equilibrium as negotiators gain experience. In addition, the results suggest that (1) positively framed negotiators (“What will be my net profit from the transaction?”) complete more transactions than negatively framed negotiators (“What will be my expenses on this transaction?”), (2) negotiators who are given moderately difficult profit constraints in order to be allowed to complete a transaction achieve more profitable transactions than negotiators without such constraints, and (3) both framing and the existence of constraints affect the total profitability of the negotiator.     

A five-dimensional model of individual differences in social exchange styles

An evolutionary psychology framework was used to develop a five-factor model of individual differences in the domain of social exchange that built on a prior two-factor model (Leybman, Zuroff, Fournier, Kelly, & Martin, 2011). Two studies examined the factor structure of the revised Social Exchange Styles Questionnaire (SESQ-II), the reliability and validity of its five scales, and the relationship between social exchange styles (SESs) and social support. Principal components and principal factor analyses of the SESQ-II in 226 undergraduates found five social exchange dimensions: Tracking, Fairness, Individualism, Benefit-Seeking, and Overinvestment. These scales showed good internal consistency and retest reliability. Multiple regression analyses demonstrated that SESs, while distinct from other personality variables, had expected relationships with several variables and predicted social support patterns.     

中国内地大学生时间管理倾向的时代变迁：1999~2020

根据社会生态系统理论, 历时系统和宏观系统可能对个体时间管理倾向的发展具有重要意义, 但间接证据表明我国大学生时间管理倾向的发展趋势不明朗, 且相关研究缺乏从社会宏观视角的切入。基于此局限, 运用横断历史元分析的方法对1999到2020年间采用青少年时间管理倾向量表(ATMDI)的215篇文献进行分析(N = 103876)。结果发现：(1)我国大学生时间管理倾向水平总体呈缓慢下降趋势, 其中时间价值感保持稳定, 时间监控观和时间效能感呈下降趋势; (2)来自社会经济因素(GDP、居民消费水平、城镇化率)、就业因素(城镇登记失业率、普通高校毕业生人数)和网络因素(互联网普及率、网民每周互联网使用时长)的7项社会指标能显著预测大学生时间管理倾向的下降; (3)我国大学生时间管理倾向在性别和高校所在地上的差异不显著。研究结果为我国大学生时间管理倾向的时代变迁提供了证据支持, 从社会宏观因素的视角扩宽了大学生时间管理倾向的影响机制模型。     

Measurement invariance tests of the Impression Management sub-scale of the Balanced Inventory of Desirable Responding

The Impression Management (IM) subscale of the Balanced Inventory of Desirable Responding (Paulhus, 1988) has been used as a proxy for common method variance in anonymous settings and as a cause of faking on personality testing in confidential settings. This study uses confirmatory factor analysis to conduct measurement invariance/equivalence tests (also known as multiple group analysis) on the IM subscale in a quasi-experiment in anonymous and confidential data collection settings. Using Brown’s (2006) bottom-up approach to Cheung and Rensvold’s (1999) model testing steps and Cheung and Rensvold’s (2002) statistical tests, the IM sub-scale was determined to have equal form, equal factor loadings, equal indicator error variances, equal factor variance, and an equal factor covariance in both 1-factor and 2-factor models in both data collection settings. Mean scale scores were significantly higher in the confidential group than in the anonymous group. These results suggest that using the IM sub-scale as a cause of faking and as a proxy for common method variance (CMV) is likely to be acceptable because the psychometric properties of the instrument are invariant across testing conditions.     

Faceted Classification: Management and Use

The paper discusses issues related to the use of faceted classifications in an online environment. The author argues that knowledge organization systems can be fully utilized in information retrieval only if they are exposed and made available for machine processing. The experience with classification automation to date may be used to speed up and ease the conversion of existing faceted schemes or the creation of management tools for new systems. The author suggests that it is possible to agree on a set of functional requirements for supporting faceted classifications online that are equally relevant for the maintenance of classifications, the creation of classification indexing tools, or the management of classifications in an authority file. It is suggested that a set of requirements for analytico-synthetic classifications may be put forward to improve standards for the use and exchange of knowledge organization systems.

What would you have as a last supper? Thoughts about death influence evaluation and consumption of food products

Terror Management Theory posits that after thinking about their own deaths, people take sides with and defend their culture by either increasing their support for worldview-consistent examples, decreasing support for worldview-threatening examples, or both. We tested the hypothesis that mortality salience leads to an increased preference for products from one’s own culture as compared to products from a foreign culture in terms of evaluation and consumption. In a product test, participants sampled local and foreign soft drinks (Study 1) or local and foreign chocolates (Study 2). As expected, relative to a control condition, mortality salience led to more accentuated evaluative preferences for local as compared to foreign products. Furthermore, the preference for the local product in terms of actual consumption was greater under mortality salience. Independent from cultural worldview defense effects mortality salience led to more impulsive behavior as indicated by an increased correspondence between eating behavior and an implicit measure tapping into impulsive processes in Study 2.
