Investigating Leader Role Congruity and Counterproductive Work Behavior

The present study sought to examine the role of fulfilled vs. unfulfilled expectations in work-related and non-work domains. Specifically, we examined how congruence and incongruence between implicit leadership theories across multiple categories of leaders (typical, ideal, and effective leaders) and characteristics recognized on one’s supervisor affect leader-member exchange (LMX), work-family conflict, and subsequent counter-productive work behavior. We tested our hypotheses using polynomial regression and response surface modeling. The results of this study showed that congruence between implicit leadership theories (ILT’s) of typical, ideal, and effective leaders and supervisor recognition, as well as incongruity between ILT’s of ideal leaders and characteristics recognized in one’s supervisor, significantly impacts perceived LMX quality with supervisors. Incongruity between ILT’s of typical and ideal leaders and supervisor recognition was also associated with higher ratings of work-family conflict (WFC). Finally, the results showed support for a significant indirect effect of congruence between ILTs of typical and ideal leaders and characteristics recognized in one’s supervisor on CWB through WFC. These results add meaningful depth to literature on congruent implicit theories in two ways: (a) we add to existing knowledge of outcomes associated with congruence on ILT’s, and, (b) we examine these associations using ILT’s across multiple categories of leaders. Implications are also discussed.     

Variations in Expected Affect in Young and Middle-Aged Adults

Expected positive and negative affects were measured in three samples of college students and in three samples of middle-aged adults. For each of the samples, negative affect decreased with age. The pattern of the effect was the same for the three samples and for the Expected Balance Scale (Staats, 1987, 1989) and the PANAS (Watson, Clark, & Tellegen, 1988). The higher negative affect in college students, in comparison to that in their middle-aged friends or parents, is contrary to popular stereotypes. This specific and differential decrease in negative affect is not consistent with theories proposing only a general decrement in emotionality with increasing age. An explanation in terms of stress appraisal, coping, and management is suggested.     

Examining the Role of Similarity Coefficients and the Value of Behavioural Themes in Attempts to Link Serial Arson Offences

When relying on crime scene behaviours to link serial crimes, linking accuracy may be influenced by the measure used to assess across‐crime similarity and the types of behaviours included in the analysis. To examine these issues, the present study compared the level of linking accuracy achieved by using the simple matching index (S) to that of the commonly used Jaccard's coefficient (J) across themes of arson behaviour. The data consisted of 42 crime scene behaviours, separated into three behavioural themes, which were exhibited by 37 offenders across 114 solved arsons. The results of logistic regression and receiver operating characteristic analysis indicate that, with the exception of one theme where S was more effective than J at discriminating between linked and unlinked crimes, no significant differences emerged between the two similarity measures. In addition, our results suggest that thematically unrelated behaviours can be used to link crimes with the same degree of accuracy as thematically related behaviours, potentially calling into the question the importance of theme‐based approaches to behavioural linkage analysis.

Circular interpretation of regression coefficients

The interpretation of the effect of predictors in projected normal regression models is not straight-forward. The main aim of this paper is to make this interpretation easier such that these models can be employed more readily by social scientific researchers. We introduce three new measures: the slope at the inflection point (b_c), average slope (AS) and slope at mean (SAM) that help us assess the marginal effect of a predictor in a Bayesian projected normal regression model. The SAM or AS are preferably used in situations where the data for a specific predictor do not lie close to the inflection point of a circular regression curve. In this case b_c is an unstable and extrapolated effect. In addition, we outline how the projected normal regression model allows us to distinguish between an effect on the mean and spread of a circular outcome variable. We call these types of effects location and accuracy effects, respectively. The performance of the three new measures and of the methods to distinguish between location and accuracy effects is investigated in a simulation study. We conclude that the new measures and methods to distinguish between accuracy and location effects work well in situations with a clear location effect. In situations where the location effect is not clearly distinguishable from an accuracy effect not all measures work equally well and we recommend the use of the SAM.     

Individual differences: Factors affecting employee utilization of flexible work arrangements

This study investigated individual and organizational factors that predict an individual’s choice to use flexible work arrangements (FWAs). Survey data was collected from 144 employees in two different organizations. The results revealed several significant predictors of FWAs: tenure, hours worked per week, supervisory responsibilities, perceptions of workgroup use and personal lifestyle. Individuals with longer tenure in the organization, who had supervisory responsibilities, had coworkers in their immediate workgroup who used FWAs or had personal lifestyle preferences were more likely to use the programs than those with less tenure, who did not have supervisory responsibilities, did not perceive their workgroup used FWAs or did not have personal lifestyle preferences.     

Fungible Weights in Multiple Regression

Every set of alternate weights (i.e., nonleast squares weights) in a multiple regression analysis with three or more predictors is associated with an infinite class of weights. All members of a given class can be deemed fungiblebecause they yield identical SSE (sum of squared errors) and R ² values. Equations for generating fungible weights are reviewed and an example is given that illustrates how fungible weights can be profitably used to evaluate parameter sensitivity in multiple regression.

The differential effects of age and first grade schooling on the development of infralogical and logico-mathematical concrete operations

Using the “between-grade levels” regression discontinuity design, this study examined the hypothesized differential sensitivity of logico-mathematical (LM) and infralogical (IL) operational tasks to the effects of chronological age and first grade schooling in a sample of 580 1st and 2nd grade Israeli children. The results indicate that the development of logico-mathematical operational skills (classification, class inclusion and transitivity) is mainly attributable to schooling. In contrast, the effect of schooling on the development of conservation of mass, liquid quantity and number (clearly an infralogical task) is negligible; acquisition of conservation is almost exclusively due to maturation and out-of-school experiences. The results support the theoretical predictions derived from French-Swiss research of the last two decades and are inconsistent with claims regarding the specificity of schooling effects to tasks that are taught in school.     

EPQ信度概化的跨文化比较及其启示

对中国7种主要的心理学杂志,于1998-2008年间发表的与EPQ有关的研究报告或论文做信度概化分析,并与Caruso等人对其他国家的EPQ信度概化分析结果作比较。分析结果表明：中外心理量表使用者都存在严重的“信度引入”的状况;分量表的分数的标准差是信度系数最重要的预测变量;但其他预测变量有所不同。提供的启示是：使用心理量表时一定要报告当前样本的信度系数;不符合心理量表特性要求而增加项目,不一定能提高测验结果的信度。
