构建职场排斥三方互动的理论模型——社会平衡理论的视角

职场排斥是一个多方互动的过程, 不仅牵涉到被排斥员工, 其他参与方对于职场排斥的产生和发展也能起到关键的作用。然而, 以往的研究大多采用被排斥者的视角, 研究职场排斥对其造成的影响, 未能全面揭示职场排斥的互动过程。从社会平衡理论的视角出发, 职场排斥可被视为被排斥者、排斥者及第三方互动的结果, 排斥者特点、第三方道德判断、排斥者与第三方交互作用都将影响职场排斥的发生及发展。由此, 职场排斥的理论视角能够得到有效拓展, 管理实践也能从中获得抑制职场排斥行为的启示。     

Deterministic blockmodelling of signed and two-mode networks: A tutorial with software and psychological examples

Deterministic blockmodelling is a well-established clustering method for both exploratory and confirmatory social network analysis seeking partitions of a set of actors so that actors within each cluster are similar with respect to their patterns of ties to other actors (or, in some cases, other objects when considering two-mode networks). Even though some of the historical foundations for certain types of blockmodelling stem from the psychological literature, applications of deterministic blockmodelling in psychological research are relatively rare. This scarcity is potentially attributable to three factors: a general unfamiliarity with relevant blockmodelling methods and applications; a lack of awareness of the value of partitioning network data for understanding group structures and processes; and the unavailability of such methods on software platforms familiar to most psychological researchers. To tackle the first two items, we provide a tutorial presenting a general framework for blockmodelling and describe two of the most important types of deterministic blockmodelling applications relevant to psychological research: structural balance partitioning and two-mode partitioning based on structural equivalence. To address the third problem, we developed a suite of software programs that are available as both Fortran executable files and compiled Fortran dynamic-link libraries that can be implemented in the R software system. We demonstrate these software programs using networks from the literature.     

Aggregating conclusive and inconclusive information: Data and a model based on the assessment of threat

This study examined the process of combining conclusive and inconclusive information using a Naval threat assessment simulation. On each of 36 trials, participants interrogated 10 pieces of information (e.g., speed, direction, bearing, etc.) about “targets” in a simulated radar space. The number of hostile, peaceful, and inconclusive cues was factorially varied across targets. Three models were developed to understand how inconclusive information is used in the judgment of threat. According to one model, inconclusive information is ignored and the judgment of threat is based only on the conclusive information. According to a second model, the amount of dominant conclusive information is normalized by all of the available information. Finally, according to a third model, inconclusive information is partitioned under the assumption that it equally represents both dominant and non‐dominant evidence. In Experiment 1, the data of novices (i.e., civilians) were best described by a model that assumes a partitioning of inconclusive evidence. This result was replicated in a second experiment involving variation of the global threat context. In a third experiment involving experts (i.e., Canadian Navy officers), the data of half of the participants were best described by the partitioning model and the data of the other half were best described by the normalizing model. In Experiments 1 and 2, the presence of inconclusive information produced a “dilution effect”, whereby hostile (peaceful) targets were judged as less hostile (peaceful) than the predictions of the Partitioning model. The dilution effect was not evident in the judgments of the Navy officers. Copyright © 2009 Crown in the right of Canada. Published by John Wiley & Sons, Ltd.     

The Influence of an Acute Bout of Whole Body Vibration on Human Postural Control Responses

The use of vibrating platforms has become increasingly available, and popular at sports and rehabilitation institutes. Given the discrepancies in the literature regarding whole body vibration (WBV) and human reflexive responses, the purpose of this study was to examine the acute effects of WBV on postural response latencies, as well as associated electromyography measures of the lower extremities during balance perturbations. Reflexive responses during backward and forward balance perturbations were examined before, after, and 10 min after a bout of WBV. The findings suggest that following an acute bout of whole body vibration, muscle activity of the lower extremities is decreased during a reflexive response to an unexpected perturbation, and may be associated with faster reaction time.     

Conversation with 2017 American Academy of Religion Excellence in Teaching award winner Lynn Neal

This conversation between the 2017 American Academy of Religion Excellence in Teaching award winner Lynn Neal and the editors of Teaching Theology and Religion continues an occasional series of interviews that has previously featured Jonathan Z. Smith, Stephen Prothero, Mary Pierce Brosmer, Mary Elizabeth Mullino Moore, and the 2016 Teaching award winner Joanne Maguire Robinson. The exchange takes as its point of departure the AAR teaching statement that Professor Neal submitted. Topics discussed include introductory courses, active learning assignments, religious intolerance and privatization, student learning outcomes, different levels of student skills and preparation, augmenting assignments through the production of video interviews with scholars, and finding conversation partners for reflecting on teaching under the life balance stresses of the academy today.     

Teamwork and flow proneness mitigate the negative effect of excess challenge on flow state

Flow theory postulates that flow experience is the most intense under high-challenge/high-skill conditions, whereas an excess of challenge is aversive. This study explores potential moderators that may offset the negative impact of overly high challenge on flow state. The literature suggests that a situational factor, teamwork, and a dispositional factor, flow proneness, may moderate the relationship between challenge and flow state. We tested these moderators with Hong Kong Chinese students whose optimal condition for experiencing flow was biased toward low-challenge/high-skill. A total of 128 participants played puzzles in three challenge levels both alone and in pairs. Although challenge level was negatively associated with flow state, dyadic (team) game (compared with solitary game) and flow proneness mitigated the negative relationship between challenge and flow state. These findings shed light on factors that promote enjoyment in challenging activities even among people in cultures that are prudent about challenges.     

Supervisor Support for Employee Performance in Australia: Mediating Role of Work‐Life Balance,Job, and Life Attitude

Drawing on the job‐demands resources model, we investigated the relationship between supervisor support and employee performance and the mediating effects of work‐life balance (WLB), job and life satisfaction, and organizational commitment in a sample of 305 financial‐sector employees in Sydney, Australia. Results reveal that supervisor support is positively related to employee performance, WLB, job and life satisfaction, and organizational commitment. In turn, WLB, job and life satisfaction, and organizational commitment are positively linked to employee performance. The findings indicate a significant mediation between supervisor support and employee performance only through WLB and organizational commitment. Implications for theory and practice are discussed.

Age effects on the control of dynamic balance during step adjustments under temporal constraints

This study investigated the age effects on the control of dynamic balance during step adjustments under temporal constraints. Fifteen young adults and 14 older adults avoided a virtual white planar obstacle by lengthening or shortening their steps under free or constrained conditions. In the anterior–posterior direction, older adults demonstrated significantly decreased center of mass velocity at the swing foot contact under temporal constraints. Additionally, the distances between the ‘extrapolated center of mass’ position and base of support at the swing foot contact were greater in older adults than young adults. In the mediolateral direction, center of mass displacement was significantly increased in older adults compared with young adults. Consequently, older adults showed a significantly increased step width at the swing foot contact in the constraint condition. Overall, these data suggest that older adults demonstrate a conservative strategy to maintain anterior–posterior stability. By contrast, although older adults are able to modulate their step width to maintain mediolateral dynamic balance, age-related changes in mediolateral balance control under temporal constraints may increase the risk of falls in the lateral direction during obstacle negotiation.
