Differentiated leader–member exchange,justice climate,and performance: Main and interactive effects

Leaders form different quality leader–member exchange (LMX) relationships with their subordinates. This variable treatment termed LMX differentiation can have negative effects on individuals' behavior and attitudes. In this study, we examined the cross-level main effect of justice climate on task performance and the moderating role of justice climate on the relationship between LMX differentiation and task performance. We tested these two hypotheses using a field study of 90 subordinates nested under 27 supervisors. Procedural justice climate, not distributive justice climate, was found to positively influence subordinate task performance. Further, distributive justice climate, not procedural justice climate, was found to moderate the LMX differentiation–task performance relationship; such that the relationship was positive when distributive justice climate was high and negative when distributive justice climate was low. Findings and future directions are discussed.     

＂Inspire Confidence, Stay Relevant＂

(Continued from the last issue)However,I did not feel I had made the right choice and the next time I saw her I apologized.She said to me I had done nothing wrong and said "it’s not your fault teacher,it’s my fault my English is too poor." But I still insisted that I had made a mistake.Yes,I had corrected her,but at what cost? The experience obviously embarrassed her,and her peers by the third time she repeated the word incorrectly had been shaking their heads.She may have left the classroom being able to pronounce the word correctly but what about the damage to her confidence? I thought about it for literally hours.I feared that perhaps next time she might not want to stand up,or shout out the answer in class in case she might be humiliated again.In her mind it was her own incompetence but for me it was my own ignorance.     

Model Uncertainty and Bayesian Model Averaged Benchmark Dose Estimation for Continuous Data

The benchmark dose (BMD) approach has gained acceptance as a valuable risk assessment tool, but risk assessors still face significant challenges associated with selecting an appropriate BMD/BMDL estimate from the results of a set of acceptable dose‐response models. Current approaches do not explicitly address model uncertainty, and there is an existing need to more fully inform health risk assessors in this regard. In this study, a Bayesian model averaging (BMA) BMD estimation method taking model uncertainty into account is proposed as an alternative to current BMD estimation approaches for continuous data. Using the “hybrid” method proposed by Crump, two strategies of BMA, including both “maximum likelihood estimation based” and “Markov Chain Monte Carlo based” methods, are first applied as a demonstration to calculate model averaged BMD estimates from real continuous dose‐response data. The outcomes from the example data sets examined suggest that the BMA BMD estimates have higher reliability than the estimates from the individual models with highest posterior weight in terms of higher BMDL and smaller 90th percentile intervals. In addition, a simulation study is performed to evaluate the accuracy of the BMA BMD estimator. The results from the simulation study recommend that the BMA BMD estimates have smaller bias than the BMDs selected using other criteria. To further validate the BMA method, some technical issues, including the selection of models and the use of bootstrap methods for BMDL derivation, need further investigation over a more extensive, representative set of dose‐response data.     

Moral conformity in online interactions: rational justifications increase influence of peer opinions on moral judgments

Over the last decade, social media has increasingly been used as a platform for political and moral discourse. We investigate whether conformity, specifically concerning moral attitudes, occurs in these virtual environments apart from face-to-face interactions. Participants took an online survey and saw either statistical information about the frequency of certain responses, as one might see on social media (Study 1), or arguments that defend the responses in either a rational or emotional way (Study 2). Our results show that social information shaped moral judgments, even in an impersonal digital setting. Furthermore, rational arguments were more effective at eliciting conformity than emotional arguments. We discuss the implications of these results for theories of moral judgment that prioritize emotional responses.     

The Development of Cross-Cultural Talent

正I believe that there are many different elements to an outstanding education today.But the element that may be the most new,the most different from what constituted an outstanding education in the past,is the need to help today’s talents to become cross-cultural talents.     

In search of message design best practices: The Silver Anvil Award winners archive

We investigated specific award-winning public relations efforts to derive best practices that bridge industry practices with academic research and pedagogy. The data for this project were the winning entries for the annual Public Relations Society of America's (PRSA) Silver Anvil Award, which is considered the top award recognizing excellence in public relations. We found, however, that the archive of award winners does not provide sufficiently definitive information about what defines any public relations discourse genre or why any genre as used is “excellent.” This archival research provides us with a key rationale for employing rhetorical, narrative, and linguistic theories prospectively to guide public relations message design and planning, theories which hitherto have been used to judge campaigns post hoc or retrospectively.     

Using the contradiction paradigm to assess ageism

Ageism is an important topic in our society, considering the burgeoning older adult population. Ageism is often measured using explicit questionnaires; however, given the impact of social desirability, implicit measures of ageism have been developed. In this study, the contradiction paradigm, an implicit measure of stereotypes (Lassonde, under review) was used to measure age-related stereotypes in passages describing older adults. Participants read passages with target sentences more slowly when these sentences described behaviors that were inconsistent rather than consistent with age-related stereotypes. Participants also completed a series of self-report questionnaires measuring ageism. Results demonstrated that reading times using the contradiction paradigm were not related to outcomes on the self-report questionnaires. A comparison of the contradiction paradigm to a social desirability scale revealed that it was not vulnerable to social desirability. This confirms the contradiction paradigm's use as an implicit measure of age-related stereotypes. Although there is no clear relation between the contradiction paradigm and popular explicit measures, a next important step would be to determine the point in which implicit knowledge and intentional behavioral responses interact.     

Tilting at windmills: a cynical assemblage of the crises of knowledge

The essay offers one piece of a larger conjunctural analysis, in an effort to contribute to a better story of the contemporary organic crisis. It considers three elements of the complexity of the ‘crises’ of knowledge: First, it explores the increasingly felt social perception that knowledge (and the forms of authority that accompany it) has become less determined and determining, less identifiable, less effective, more troubled. It argues that one must think about these developments historically and contextually, rather than going along with the panic that has surrounded their increasing visibility in recent political events. Second, it considers some of the attacks on the university as well as some of the recent changes in the political economy and institutional forms of the academy. Finally, it argues that academics have failed to examine their own contributions to the crises of knowledge, failed to consider the ways their own cultures and practices can be located within rather than against the crises of knowledge.
