Factor analysis is regularly used for analyzing survey data. Missing data, data with outliers and consequently nonnormal data are very common for data obtained through questionnaires. Based on covariance matrix estimates for such nonstandard samples, a unified approach for factor analysis is developed. By generalizing the approach of maximum likelihood under constraints, statistical properties of the estimates for factor loadings and error variances are obtained. A rescaled Bartlett-corrected statistic is proposed for evaluating the number of factors. Equivariance and invariance of parameter estimates and their standard errors for canonical, varimax, and normalized varimax rotations are discussed. Numerical results illustrate the sensitivity of classical methods and advantages of the proposed procedures.This project was supported by a University of North Texas Faculty Research Grant, Grant #R49/CCR610528 for Disease Control and Prevention from the National Center for Injury Prevention and Control, and Grant DA01070 from the National Institute on Drug Abuse.

This study examines the effect of leader moral development on the organization’s ethical climate and employee attitudes. Results indicate that the relationship between leader moral development and ethical climate is moderated by two factors: the extent to which the leader utilizes his or her cognitive moral development (i.e., capacity for ethical reasoning), and the age of the organization. Specifically, the influence of the leader’s moral development was stronger for high utilizing leaders, those whose moral actions were consistent with their moral reasoning. Additionally, the influence of the leader’s moral development was stronger in younger organizations. Finally, as predicted, congruence between the leader’s moral development and the employee’s moral development was positively associated with job satisfaction and organizational commitment and negatively associated with turnover intentions. 相似文献

Mindfulness‐based meditation practices have received substantial scientific attention in recent years. Mindfulness has been shown to bring many psychological benefits to the individual, but much less is known about whether these benefits extend to others. This meta‐analysis reviewed the link between mindfulness – as both a personality variable and an intervention – and prosocial behaviour. A literature search produced 31 eligible studies (N = 17,241) and 73 effect sizes. Meta‐analyses were conducted using mixed‐effects structural equation models to examine pooled effects and potential moderators of these effects. We found a positive pooled effect between mindfulness and prosocial behaviour for both correlational (d = .73 CI 95% [0.51 to 0.96]) and intervention studies (d = .51 CI 95% [0.37 to 0.66]). For the latter, medium‐sized effects were obtained across varying meditation types and intensities, and across gender and age categories. Preliminary evidence is presented regarding potential mediators of these effects. Although we found that mindfulness is positively related to prosociality, further research is needed to examine the mediators of this link and the contexts in which it is most pronounced. 相似文献

Three patterns of mutual intimate partner violence (IPV) are proposed, based on frequency and severity: Male primary perpetrator
(MPP), female primary perpetrator (FPP), and symmetrical (SYM). Patterns and effects of ethnicity were examined with 445 African
American, Euro-American, and Mexican American low-income women experiencing mutual IPV. More relationships were classified
as MPP (54%) than SYM (35%) or FPP (11%). Comparing women's and men's perpetration of several types of IPV (e.g., threats,
severe physical) indicated MPP-pattern women experienced all IPV types more often and were more likely to sustain injury than
their male partners. Fewer gender differences were found in the FPP pattern. Racial/ethnic groups were more similar than different;
previously reported differences may be explained by variation in socioeconomic status.

Consumer Search in High Technology Markets: Exploring the Use of Traditional Information Channels 总被引:1,自引:0,他引:1
Understanding the use of information channels during the purchase process for high technology durable goods is vital if marketing managers want to efficiently allocate their communication budgets. This article examines how the perceived quality of information, as well as demographic and other consumer characteristics, affects consumers’ information‐channel‐choice behavior. The results suggest that (a) information channels operate as substitutes as far as information quality is concerned; (b) during each segment of the search consumers tend to use multiple sources of information, and in that context information channels act as complements, which illustrates the synergistic effect of search between channels and the importance of jointly estimating consumers’ information channel choices; and (c) utility derived from information search changes as time passes, which indicates that empirical research should use panel data to capture the dynamics of the search process. 相似文献

Currently, there is no standard self-report measure of psychopathy in community-dwelling samples that parallels the most commonly used measure of psychopathy in forensic and clinical samples, the Psychopathy Checklist. A promising instrument is the Self-Report Psychopathy scale (SRP), which was derived from the original version the Psychopathy Checklist. The most recent version of the SRP (SRP-III; D. L. Paulhus, C. S. Neumann, & R. D. Hare, in press) has shown good convergent and discriminate validity and a factor structure similar to the current version of the Psychopathy Checklist (PCL-R; R. D. Hare, 1991, 2003). The analyses in the current study further investigated the viability of the SRP-III as a PCL-R-analogous measure of psychopathy in nonforensic and nonclinical samples by extending the validation process to a community sample. Using confirmatory factor analyses and logistic regressions, the results revealed that a four-factor oblique model for the SRP-III was most tenable, congruent with the PCL-R factor structure of psychopathy and previous research in which the SRP-III was administered to a student sample. 相似文献

The cultural psychology of romantic relationships is relatively understudied. To redress this lacunae, the present study examined the Japanese concept of ‘amae’, or the state of expecting a close other's indulgence when one behaves inappropriately, within the day‐to‐day relationships of 30 Japanese undergraduate romantic couples. For 2 weeks, both partners completed daily diaries that assessed their amae behaviour (requesting, receiving, and providing amae), relationship quality, conflict, and motivation to enhance closeness. Results revealed that amae behaviour was associated with greater relationship quality and less conflict. The motivation to enhance closeness partially mediated the association of amae with relationship quality. 相似文献
