Weights may be determined for combining tests so that the composite has maximum reliability, but the calculation of these weights by means of the original equations is cumbersome. It is shown that the desired weighted composite is the first principal axis of a matrix closely related to the intercorrelation matrix. Thus, simple and straightforward procedures are available for calculating the weights. 相似文献

In order to explain the diverging well‐being outcomes of workaholism, this study aimed to examine the motivational orientations that may fuel the two main components of workaholism (i.e. working excessively and working compulsively). Drawings on Self‐Determination Theory, both autonomous and controlled motivation were suggested to drive excessive work, which therefore was expected to relate positively to both well‐being (i.e. vigor) and ill‐health (i.e. exhaustion). Compulsive work, in contrast, was hypothesised to originate exclusively out of controlled motivation and therefore to only associate positively with ill‐being. Structural equation modeling in a heterogeneous sample of Belgian white‐collar workers (N= 370) confirmed that autonomous motivation associated positively with excessive work, which then related positively to vigor. Controlled motivation correlated positively with compulsive work, which therefore related positively with exhaustion. The hypothesised path from controlled motivation to exhaustion through excessive work was not corroborated. In general, the findings suggest that primarily compulsive work yields associations with ill‐being, since it may stem from a qualitatively inferior type of motivation. 相似文献

Generic price terms such as cheap, not expensive, not cheap, and expensive are used frequently in marketing, but little is known about how consumers interpret them. In typical consumer contexts, in which lower prices are preferred, we find that not cheap means essentially the same as expensive (i.e., not cheap = expensive). In contrast, not expensive does not mean the same as cheap, in that cheap is associated with lower prices (i.e., cheap < not expensive). As an implication, in a consumer survey we find different response distributions for rating scales that are anchored with endpoint labels of not expensive versus expensive as compared to cheap versus expensive or cheap versus not cheap (the latter two are equivalent). Furthermore, although cheap is associated with lower prices than not expensive, this does not necessarily translate into higher preferences for options that are described as cheap (vs. not expensive), because cheap may also evoke negative quality perceptions. Finally, we demonstrate an interesting reversal in the way price terms are interpreted: when higher prices are preferred, cheap is equal to not expensive (i.e., cheap = not expensive), whereas not cheap is associated with lower prices than expensive (i.e., not cheap < expensive). 相似文献

There is scant research on how the parenting practices of custodial grandmothers affect the psychological adjustment of grandchildren in their care. Yet, the findings from a handful of prior studies suggest the relevance of the Family Stress Model (FSM) to these caregivers. The present study further tested the FSM with baseline data from 343 custodial grandmothers (Mage?=?58.5 years) enrolled in a clinical trial of the efficacy of interventions for improving the well-being of their families. Not only was this “help-seeking” sample atypical of prior FSM studies, but also unique to the present study was our addition of multiple parenting practices, self-reported and clinical ratings of grandmothers’ distress, and reports of grandchildren’s internalizing and externalizing difficulties from grandchildren and grandmothers. Mplus 7.31 was used to test a model where the effect of grandmother distress on grandchildren’s internalizing and externalizing difficulties was hypothesized to be indirect through five distinct parenting practices. The findings regarding both the measurement and structural models fit the observed data well, and invariance was largely found across grandchildren’s gender and age (4–7 vs. 8–12). Although grandchildren’s self-reported internalizing and externalizing difficulties were unrelated to grandmothers’ distress and parenting practices, the grandmothers’ reports of these outcomes were generally related to their own distress and parenting practices as hypothesized. However, considerable variation was found across the five parenting practices in terms of their relationships to the other FSM constructs. We conclude that data from multiple informants and measures of assorted parenting practices are essential to future research and practice. 相似文献

This document presents the Bonn PRINTEGER Consensus Statement: Working with Research Integrity—Guidance for research performing organisations. The aim of the statement is to complement existing instruments by focusing specifically on institutional responsibilities for strengthening integrity. It takes into account the daily challenges and organisational contexts of most researchers. The statement intends to make research integrity challenges recognisable from the work-floor perspective, providing concrete advice on organisational measures to strengthen integrity. The statement, which was concluded February 7th 2018, provides guidance on the following key issues:

Conclusion From the small sample of achievements that I have had time to mention, we can only conclude that automation is here to stay. Nor is there any doubt that more powerful automata will be built. A great many of the higher human abilities will be given to machines. The great rush to automation is sure to stimulate psychologists to learn more about the human symbolic processes being mimicked by the machines. And the computers, which are the ultimate cause of the feverish scramble toward automation, are providing both the framework for describing complex models of behavior and also the means for testing these models. With both the means and the motivation at hand, psychologists are sure to make rapid progress in understanding complex human behavior.Operated with support from the United States Army, Navy, and Air Force. 相似文献
