A motivated information processing perspective on the antecedents of empowering leadership

Empowering leadership is an important influence on team effectiveness. This makes the question of what the antecedents of team empowering leadership are an important issue to consider. To address this question, we propose a motivated information processing perspective that holds that engaging in empowering leadership is based on social information processing, and that there are individual differences in how elaborate that information processing is. We argue that a key consideration in shifting control from the leader to the team is the extent to which empowering leadership is driven by leaders’ consideration of their trust in the team (i.e., an instance of social information processing), and that leader need for closure (a trait capturing the disposition to carefully consider decisions and actions) moderates the relationship between leader trust in team and empowering leadership. A survey of N = 156 work teams supported these hypotheses.     

A Monte Carlo study comparing PIV,ULS and DWLS in the estimation of dichotomous confirmatory factor analysis

We conducted a Monte Carlo study to investigate the performance of the polychoric instrumental variable estimator (PIV) in comparison to unweighted least squares (ULS) and diagonally weighted least squares (DWLS) in the estimation of a confirmatory factor analysis model with dichotomous indicators. The simulation involved 144 conditions (1,000 replications per condition) that were defined by a combination of (a) two types of latent factor models, (b) four sample sizes (100, 250, 500, 1,000), (c) three factor loadings (low, moderate, strong), (d) three levels of non‐normality (normal, moderately, and extremely non‐normal), and (e) whether the factor model was correctly specified or misspecified. The results showed that when the model was correctly specified, PIV produced estimates that were as accurate as ULS and DWLS. Furthermore, the simulation showed that PIV was more robust to structural misspecifications than ULS and DWLS.     

The influence of between and within-person hope among emergency responders on daily affect in a stress and coping model

This study reports on daily hope, coping, stress, and affect among 84 fire service members who completed a 21-day diary. Multilevel modeling showed that between-person hope was related to higher positive affect. Three-way interactions were found for within-person hope, stress, and daily coping in the prediction of daily affect. When under high stress and if low in hope, more emotion–expression coping predicted higher next day positive affect whereas if high in hope, more problem-focused coping predicted more positive affect. Within-person hope, stress, and emotion–expression coping interacted to predict negative affect. Findings for the prediction of negative affect necessitate further research to determine if the nature of coping under low hope and low stress is qualitatively distinct from high hope states.     

J.S. Mill's Canons of Induction: From True Causes to Provisional Ones

In this essay, my aim is twofold: to clarify how the late Mill conceived of the certainty of inductive generalisations and to offer a systematic clarification of the limited domain of application of Mill's Canons of Induction. I shall argue that Mill's views on the certainty of knowledge changed over time and that this change was accompanied by a new view on the certainty of the inductive results yielded by the Canons of Induction. The key message of the later editions of The System of Logic as conceived by the late Mill was no longer that by the Canons of Induction we can establish scientific certainty and true causes, but rather that the Canons are useful in establishing causal laws in a provisional way.

Examining antecedents and outcomes of part‐time working nurses' motives to search and not to search for a full‐time position

Grounded in self‐determination theory, this study sought to examine the antecedents and outcomes of part‐time working nurses' (n = 404) motives for searching and not searching for full‐time employment. After controlling for various background variables, autonomous motivation and economic motivation to search for a full‐time job related positively to job search intensity, controlled motivation to search related negatively to experienced positive experiences of part‐time work, whereas autonomous motivation not to search related negatively to job search intensity and positively to positive experiences from part‐time work. Finally, experienced managerial autonomy support toward part‐time work and negative feedback from colleagues regarding part‐time work were established as contextual antecedents of part‐time nurses' autonomous and controlled motives to search and not to search.     

A Computationally More Efficient and More Accurate Stepwise Approach for Correcting for Sampling Error and Measurement Error

Over the last decade or two, multilevel structural equation modeling (ML-SEM) has become a prominent modeling approach in the social sciences because it allows researchers to correct for sampling and measurement errors and thus to estimate the effects of Level 2 (L2) constructs without bias. Because the latent variable modeling software Mplus uses maximum likelihood (ML) by default, many researchers in the social sciences have applied ML to obtain estimates of L2 regression coefficients. However, one drawback of ML is that covariance matrices of the predictor variables at L2 tend to be degenerate, and thus, estimates of L2 regression coefficients tend to be rather inaccurate when sample sizes are small. In this article, I show how an approach for stabilizing covariance matrices at L2 can be used to obtain more accurate estimates of L2 regression coefficients. A simulation study is conducted to compare the proposed approach with ML, and I illustrate its application with an example from organizational research.     

How Children Determine the Size of 3D Structures: Investigating Factors Influencing Strategy Choice

This study explores changes in students’ strategies as they solve different types of volume problems. Fifth graders were presented with pictures showing 3D objects and a unit cube; they determined how many cubes made up the object and explained their responses. We examined whether children transferred strategies across problem types, varying in terms of (a) availability of grids that divided objects into individual unit cubes, (b) order of items, (c) object shape, and (d) availability of the unit cube. Children's strategy choices varied systematically with object and task characteristics. They were more likely to use conceptually appropriate strategies when presented with grids. With non-gridded objects, they were more likely to treat a 3D object as a collection of 2D faces. Presenting gridded items first increased the use of conceptually appropriate strategies on the non-gridded items. We discuss findings in the context of Siegler's theory of strategy choice and address educational implications.     

When the half-full glass is appraised as half empty and memorised as completely empty: Mood-congruent true and false recognition in depression is modulated by salience

Since the 1980s a large body of empirical effort has been devoted to mood-congruent memory (MCM) biases in clinical depression. Whereas there is broad, albeit not unequivocal, evidence that depressive patients retain negative-valenced memory items better than neutral material, few studies have investigated false memories in depression. In a pilot study we gathered support for both enhanced true and false memory for emotional material in depression. The present study aimed to extend these preliminary findings. In view of investigations suggesting that arousing and meaningful stimuli have facilitated access to memory, personal salience was considered a moderator for MCM. In the present study 21 depressed and 22 healthy participants were presented six false memory lists dealing with neutral, negative, and positive themes. At recognition, each item had to be appraised for its degree of valence subsequent to an old–new judgement. Pre-categorised and subjective valence did not discriminate groups. However, relative to controls depressed patients showed both more veridical as well as false recognition for items that concurrently elicited higher salience ratings in patients. In contrast, group differences in recognition performance did not significantly affect salience ratings. Results indicate that salience modulates MCM and may account for discrepancies in the literature.
