Correction for Range Restriction in Meta‐Analysis Revisited: Improvements and Implications for Organizational Research 下载免费PDF全文
In this study, we present a more accurate method for correcting for range restriction (Case V) that expands upon Bryant and Gokhale's (1972) method. We further present detailed steps to incorporate the Case V method into Schmidt and Hunter's (2015) psychometric meta‐analysis methods (both individual correction and artifact distribution approaches). We then evaluate the accuracy of the Case V method vis‐à‐vis existing methods. Monte‐Carlo simulation results indicate that the Case V method provides very accurate estimates for the mean true score correlation and reasonably accurate estimates for the true standard deviation. More important, Case V almost always provides more accurate results than alternative methods (particularly, Case IV). To illustrate how the Case V method works with real data, we conduct a reanalysis of Judge, Heller, and Mount's (2002) meta‐analysis examining the relationships between the Big 5 personality traits and job satisfaction. Results indicate that the true score correlations between the Big 5 traits and job satisfaction have been underestimated, whereas their true standard deviations have been overestimated. Implications for range restriction corrections in organizational research are discussed. 相似文献

In continuing news, there is a growing debate on whether current laws and regulations, both in the US and abroad, need to
be strengthened as they relate to nanotechnology. On one side, experts argue that nanomaterials, which are making their way
into the marketplace today, are possibly harmful to consumers and the environment, so stronger and new laws are needed to
ensure they are safe. On the other side, different experts argue that more regulation will slow down the pace of business
and innovation in nanotechnology, or that self-regulation is the answer, or other opposing positions. This paper will draw
out the core issues behind the debate and explain that there is more at stake than merely environmental, health and safety
(EHS) worries or business interests, as it first appears. We will also suggest an alternative solution to stricter laws, since
stricter laws would face formidable practical challenges, even if they are warranted. 相似文献

In this article, we describe a systematic review of mean race and sex differences in situational judgment test (SJT) performance. On average, White test takers perform better on SJTs than Black, Hispanic, and Asian test takers. Female examinees perform slightly better than male test takers on SJTs. We investigate two moderators of these differences: loading of g or personality on the SJT, and response instructions. Mean race differences between Black, Hispanic, Asian and White examinees in SJT performance are largely explained by the cognitive loading of the SJT such that the larger the cognitive load, the larger the mean race differences. Regarding the effect of personality loadings of SJTs on race differences, Black–White and Asian–White differences are smaller to the extent that the SJT is correlated with emotional stability and Hispanic–White differences are smaller to the extent that SJTs are correlated with conscientiousness and agreeableness. Cognitive loading has minimal effect on male–female SJT score differences; however, SJT score differences are larger, favoring women, when SJTs are correlated with conscientiousness and agreeableness. Concerning response instructions, knowledge response instructions showed greater race differences than behavioral tendency instructions. The mean correlations show that these differences are largely because of the greater g loading of knowledge instructions. A second study showed that when used in hiring, SJTs are likely to have adverse impact by race but not by sex. 相似文献

This study examined the efficacy of corrected feedback for improving consent recall throughout the course of an ongoing longitudinal study. Participants (N = 135) were randomly assigned to either a corrected feedback or a no-feedback control condition. Participants completed a consent quiz 2 weeks after consenting to the host study and at months 1, 2, and 3. The corrected feedback group received corrections to erroneous responses and the no-feedback control group did not. The feedback group displayed significantly greater recall overall and in specific content areas (i.e., procedures, protections, risks/benefits). Results support the use of corrected feedback for improving consent recall. 相似文献

Individual Differences in the Consideration of Future and (More) Immediate Consequences: A Review and Directions for Future Research 下载免费PDF全文
In 1994, Strathman, Gleicher, Boninger, and Edwards (1994) introduced the 12‐item consideration of future consequences scale to measure individual differences in the extent to which people base their decisions on the immediate versus future consequences of their actions. After tracing the origin and development of the CFC construct, theoretical models, including the awareness and concern models, buffering and susceptibility models, and an integrative model of CFC are outlined. Next, a narrative review of work examining the role of CFC within several outcome domains is presented, including research in the areas of health, financial, work, ethical, and environmental behaviors and decision‐making. Measurement issues including the dimensionality of the scale and adaptation to specific domains (e.g., healthy eating) are subsequently considered, and eight directions for future research are discussed. 相似文献

The causes of the positive relationship between comprehension and measures of working memory capacity remain unclear. This study tests three hypotheses for the relationship by equating the difficulty, for 48 individual subjects, of processing demands in complex working memory tasks. Even with difficulty of processing equated, the relationship between number of words recalled in the working memory measure and comprehension remained high and significant. The results favour a general capacity view. We suggest that high working memory span subjects have more limited-capacity attentional resources available to them than low span subjects and that individual differences in working memory capacity will have implications for any task that requires controlled effortful processing. 相似文献

Although some have argued that goal orientation could be beneficially integrated into organizational research, progress in this area has been impeded by several problematic conceptual issues and a lack of validated dispositional measures. This research was intended to address these issues and to provide a foundation for future organizational research in this area. We argue that goal orientation is a two-dimensional construct that has both dispostional and situational components. In each of four independent studies, LISREL VIII confirmatory factor analyses (Jöreskog & Sörbom, 1993) illustrated that a two-factor model fit a set of goal orientation items better than a single-factor model. In addition, the latent goal orientations were found to be uncorrelated in each study. Moreover, correlational analyses indicated that demographic and substantive variables exhibited differential relationships with the latent learning goal and performance goal orientation constructs. Other analyses illustrated that the dispositional and situational aspects of goal orientation are distinguishable. Collectively, the results provided ample support for the convergent and discriminant validity of eight-item measures of each goal orientation and help to define the nomological network within which the two goal orientations reside. The importance of goal orientation as a multidimensional construct is discussed and several recommendations for further research are suggested. 相似文献

Based on a general review of international, representative tissue banking policies that were described in the medical, ethics, and legal literature, this paper reviews the range of standards, both conceptually and in existing regulations, relevant to four main factors:(1) commercialization, (2) confidentiality, (3) informed consent, and (4) quality of research. These four factors were selected as reflective of some of the major ethical considerations that arise in the conduct of tissue banking research. The authors emphasize that any policy or ethical guidelines designed to regulate tissue bank research should address all four factors. Whenever this sort of research is conducted between several institutions or several countries, the paper suggests that the relevant entities work collaboratively to harmonize their standards. 相似文献

Specific language impairment (SLI) comprises impairments in receptive and/or expressive language. Aim of this study was to evaluate a screening for SLI. 61 children with SLI (SLI-children, age-range 4–6 years) and 61 matched typically developing controls were tested for receptive language ability (Token Test—TT) and for intelligence (Wechsler Preschool-and-Primary-Scale-of-Intelligence—WPPSI). Group differences were analyzed using t tests, as well as direct and stepwise discriminant analyses. The predictive value of the WPPSI with respect to TT performance was analyzed using regression analyses. SLI-children performed significantly worse on both TT and WPPSI (\(p \le .0001\)). The TT alone yielded an overall classification rate of 79%, the TT and the WPPSI together yielded an overall classification rate of 80%. TT performance was significantly predicted by verbal intelligence in SLI-children and nonverbal intelligence in controls whilst WPPSI subtest arithmetic was predictive in both groups. Without further research, the Token Test cannot be seen as a valid and sufficient tool for the screening of SLI in preschool children but rather as a tool for the assessment of more general intellectual capacities. SLI-children at this age already show impairments typically associated with SLI which indicates the necessity of early developmental support or training. Token Test performance is possibly an indicator for a more general developmental factor rather than an exclusive indicator for language difficulties. 相似文献

Research on mindfulness interventions with adolescents has burgeoned over the last ten years, and findings have demonstrated increases in overall emotional wellbeing post-intervention. However, little is known about the sex differences in response to mindfulness interventions in this age group. In the present study we examine sex differences in outcomes of physiological stress markers during the Trier Social Stress Test (TSST) and emotional wellbeing measures before and after a mindfulness intervention (N?=?15) with 10 female and 5 male adolescents. Additionally, we examine sex differences in course engagement and post-intervention use of mindfulness skills during the TSST. Overall, we found some evidence that females were more engaged than males in the class and also reported less stress post-intervention. We conclude by strongly encouraging future research in this area to more clearly elucidate the different ways in which adolescent males and females engage and respond to mindfulness interventions. 相似文献

Purpose
Organizational creativity research has a curious misalignment between construct definitions and measurement model specifications—definitions embrace multiple facets, but empirical measures do not. The purpose of this study was to examine potential measurement model misspecification in organizational creativity research. We compare whether creativity is best assessed as a unidimensional common latent construct model with reflective indicators or as a multi-dimensional composite latent construct model with formative indicators. 相似文献15.

Technological advances and other rapid changes can only be managed by leaders who understand these changes and act rather than react. The modern minister will need to become more comfortable with applied research as a necessary skill. Virtually every profession respects, uses, and invests in applied research. Ministers, however, resist. This article identifies and addresses this resistance. 相似文献
