Much of the recent research on counterproductive work behaviors (CWBs) has used multi-item self-report measures of CWB. Because of concerns over self-report measurement, there have been recent calls to collect ratings of employees' CWB from their supervisors or coworkers (i.e., other-raters) as alternatives or supplements to self-ratings. However, little is still known about the degree to which other-ratings of CWB capture unique and valid incremental variance beyond self-report CWB. The present meta-analysis investigates a number of key issues regarding the incremental contribution of other-reports of CWB. First, self- and other-ratings of CWB were moderately to strongly correlated with each other. Second, with some notable exceptions, self- and other-report CWB exhibited very similar patterns and magnitudes of relationships with a set of common correlates. Third, self-raters reported engaging in more CWB than other-raters reported them engaging in, suggesting other-ratings capture a narrower subset of CWBs. Fourth, other-report CWB generally accounted for little incremental variance in the common correlates beyond self-report CWB. Although many have viewed self-reports of CWB with skepticism, the results of this meta-analysis support their use in most CWB research as a viable alternative to other-reports.  相似文献

Early pubertal timing places girls at elevated risk for a breadth of negative outcomes, including involvement in delinquent behavior. While previous developmental research has emphasized the unique social challenges faced by early maturing girls, this relation is complicated by genetic influences for both delinquent behavior and pubertal timing, which are seldom controlled for in existing research. The current study uses genetically informed data on 924 female-female twin and sibling pairs drawn from the National Longitudinal Study of Adolescent Health to (1) disentangle biological versus environmental mechanisms for the effects of early pubertal timing and (2) test for gene-environment interactions. Results indicate that early pubertal timing influences girls' delinquency through a complex interplay between biological risk and environmental experiences. Genes related to earlier age at menarche and higher perceived development significantly predict increased involvement in both nonviolent and violent delinquency. Moreover, after accounting for this genetic association between pubertal timing and delinquency, the impact of nonshared environmental influences on delinquency are significantly moderated by pubertal timing, such that the nonshared environment is most important among early maturing girls. This interaction effect is particularly evident for nonviolent delinquency. Overall, results suggest early maturing girls are vulnerable to an interaction between genetic and environmental risks for delinquent behavior.  相似文献

Philosophy is an ambitious, speculative practice, aimed at finding out what wisdom is and how to attain it, in so far as that can be done by explicit discussion and argument. A likely pitfall of any such enterprise is that it loses touch with concerns in human life outside itself and becomes scholastic, in the pejorative sense. Academic institutions which encourage wide and outward‐looking intellectual sympathies, and which do not reward narrow point‐scoring specialism, are helpful in resisting the tendency to scholasticism. The Moral Sciences Tripos at Cambridge might have provided some of the elements of such a setting, by framing an academic structure in which philosophy was studied in conjunction with other subjects in the humanities and social sciences. As things actually developed, that possibility was not realised. Nevertheless, philosophy at Cambridge maintained vigour and significance, through the intellectual freedom and encouragement it provided to some notable individual philosophers.  相似文献

Although an ethical sanction is viewed as an incredibly stressful event for professional counselors, the experience of being sanctioned is not well known. This article provides an overview of the sanctioning process, a discussion of professional silence, and a case example of a sanctioning experience for a counselor. The sanctioning experience is described in a 3‐stage response sequence and is illustrated with journal entries from a sanctioned counselor. Response interventions for each stage are suggested, and implications for the counseling profession are offered.  相似文献

This study examined whether attachment to God moderated the relation between perceived stress and well‐being (i.e., life satisfaction and positive affect) among 183 Chinese Christian international students and immigrants. Results showed significant main effects of (a) perceived stress on life satisfaction and (b) secure attachment to God and avoidant attachment to God on life satisfaction and positive affect. There was a significant interaction of perceived stress and avoidant attachment to God on life satisfaction. Specifically, high avoidant attachment to God exacerbated the association between perceived stress and life satisfaction, whereas low avoidant attachment to God buffered the association between perceived stress and life satisfaction.  相似文献

Informed by a trans‐theoretical model of the therapeutic alliance in conjoint family therapy, this exploratory study was the initial stage in a task analysis of critical shifts in adolescent engagement. Specifically, we compared sessions in which a resistant adolescent either did or did not shift from negative to positive engagement during the session. Two successful and two unsuccessful change events were selected from an archival data set based on SOFTA ratings of the therapeutic alliance. The results suggested that one parent element (support) and five therapist elements (structuring therapeutic conversations, fostering autonomy, building systemic awareness, rolling with resistance and understanding the adolescent's subjective experience) seemed critical for successfully facilitating adolescent engagement. The qualitative results were informed by the adolescent's self‐reported target complaints pretreatment, which suggested varying reasons for the teenagers’ active or passive disengagement. Implications for practice and recommendations for future research are offered to continue this line of inquiry.  相似文献

Teenage drivers have been shown to have some of the highest crash risks. Crash data provide some insights on factors related to crash likelihood, but rarely capture all issues that can arise from driver distraction. The goal of this study was to assess teenage drivers’ opinions and perceptions of driver distraction. A survey of 1893 Iowa teenagers was conducted to determine and compare the frequency of engagement in distracting activities while driving to their opinions of what they actually consider to be distractions. A cluster analysis was conducted based on their indicated engagement in distracting activities with three groups emerging and classified as INFREQUENT, MODERATE, and FREQUENT engagers. Across all cluster groups, the majority (over 80%) indicated that they considered text messaging to be a distracting task. However, those clustered as FREQUENT engagers still reported a high level of texting while driving even though they considered this task to be distracting. A binary logistic regression model (adjusted for miles driven and license type) showed that FREQUENT and MODERATE engagers were more likely to be involved in a crash when compared to INFREQUENT engagers. The study demonstrates that not all teenagers place themselves at risk. There are subgroups of teenage drivers that often engage in activities they know are distracting, potentially putting themselves in danger. However, this is not the case for all teenage drivers and it is important to target interventions appropriately as well as foster a culture of safety both in schools and at home.  相似文献

Though often discussed as a discrete event, puberty comprises one segment of a larger developmental continuum and is notable for rapid transformation across a multitude of domains. While an earlier timing of puberty relative to peers stands as one of the most well-replicated antecedents of adolescent difficulties for girls, findings have been less consistent for boys’ development. The current review synthesizes the research on pubertal timing and psychosocial development in adolescent boys. Results are evaluated in the context of three theoretical perspectives by which precocious development is believed to affect the emergence of adverse outcomes: biological, psychosocial and selection.  相似文献

We have analyzed the impact of Section 6 of The Kenya HIV and AIDS Prevention Act on Kenyan families and especially within marriage. In 2006 Kenya passed two bills into law: The Kenya HIV and AIDS Prevention Act and The Sexual Offences Act. The latter addresses sexual offenses including rape, incest and other acts of sexual violence and relates to the Prevention Act in that HIV infection may be transmitted during a sexual offense. Section 6 of the Prevention Act focuses on the sensitive issue of secondary and tertiary transmission of HIV. Although protection is accorded to individuals living with HIV, this section of the law places responsibility on this group to reduce infections among positive individuals as well as the spread of infection between spouses {when only one partner is positive} by criminalizing recklessness leading to HIV infection. By asking questions proposed in the family impact analysis such as, does the law enhance family stability, and commitment or does it acknowledge diverse family forms, interdependence and target vulnerable groups, the framework allows us to examine the impact of Section 6 of the law on families. Under the FIA framework, the ability of The Prevention Act to enhance family functions, promote wellbeing, marital stability, commitment and responsibility is considered while taking into account the contextual realities in Kenya.  相似文献
