Despite ample research on commitment in industrial settings, there has been no systematic attempt to investigate outcomes associated with teacher commitment. Therefore, the aim of this study was to examine the relationship between teacher commitment and psychological well-being in the work place using questionnaires. Hong Kong teachers (N?=?857) participated. Hierarchical regression analyses were used to investigate how the three aspects of commitment pertaining to the organisation and occupation predicted relevant outcomes. Results showed that affective and normative commitment positively predicted psychological well-being in the work place: interpersonal fit at work, thriving at work, feeling of competency, perceived recognition at work, desire for involvement at work and job satisfaction. Continuance commitment was a negative predictor of some outcomes. Results of the current study provide support to Meyer’s 3?×?2 factor model of commitment. Findings are discussed in relation to the situation of teachers in the Hong Kong context.  相似文献

In this paper, data from the Baccalaureate & Beyond 93/97/03 survey is used to estimate the effects on the earnings of scholarship athletics participants subsequent to graduation. Former college athletes are found to have higher wages on average. Upon first glance, colleges and universities could use these results to argue on behalf of investments in athletics. However, by using quantile regression, it is shown that the positive wage premiums are not equivalent for all college athletes.  相似文献

Morin and Marsh (2015) proposed a methodological framework to disentangle shape and level effects in latent profile analyses. We discuss limitations of this framework (based on a logic similar to that of higher-order measurement models), and suggest that these limitations are easily solved by a more thorough examination of the variable-centered measurement models underlying profile indicators. This study presents complementary variable- and person-centered approaches aiming to assess the dimensionality of psychometric constructs. Psychometric measures often assess separate conceptually-related facets of global overarching constructs, based on the assumption that these overarching constructs exist as global entities including specificities mapped by the facets. The framework proposed here explicitly models this dimensionality in both variable- and person-centered analyses. To illustrate this revised psychometric framework, we use ratings of psychological health collected from 1,232 teachers, and show how this revised framework provides a clearer picture of teachers’ profiles of psychological health.  相似文献

Objective

Paternity is uncertain, so if paternal feelings evolved to promote fitness, we might expect them to vary in response to variables indicative of paternity probability. We therefore hypothesized that the risk of lapses of paternal affection, including abusive assaults on children, will be exacerbated by cues of non-paternity.

Methods

Cross-sectional study of 331 Brazilian mothers, interviewed about 1 focal child (age 1–12) residing with her and the putative father. Child physical abuse was assessed using the Conflict Tactic Scales: Parent Child (CTSPC). Two potential cues of (non) paternity were (1) whether the parents co-resided when the child was conceived, and (2) whether third parties allegedly commented on father–child resemblance. Data were analyzed through multiple logistic regressions.

Results

Mothers reported child physical abuse by 15.9% (95% CI 4.6–27.1) of fathers who had not cohabited with them at conception, compared to 5.9% (95% CI 3.1–8.7) of those who had. The odds ratio for abuse by fathers who had not cohabited at conception in relation to those who had—adjusted for income, education, age, sex of child, whether child was first born, household size, time father spent with child, and alcohol abuse and drug use by father—was 4.3 (95% CI 1.4–13.8). Mothers reported abuse of 7.0% (95% CI 4.0–10.0) of children who purportedly resembled their fathers, versus 8.7% (95% CI 0.2–17.1) of those who did not.

Conclusion

According to maternal reports, not having co-resided at conception quadrupled the chance of child physical abuse by currently co-residing Brazilian fathers. The reported prevalence of abuse was unrelated to reported allegations of father–child resemblance.  相似文献

Purpose: To compare the effects of three water-based resistance trainings on neuromuscular parameters of older women. Method: Thirty-six women were randomized to groups: simple set of 30 seconds (1 × 30 s, 66.41 ± 4.71 years, n = 12), multiple sets of 10 seconds (3 × 10 s, 66.50 ± 4.74 years, n = 11), and simple set of 10 seconds (1 × 10 s, 65.23 ± 3.93 years, n = 13). Maximal isometric strength concomitantly with neuromuscular activity during extension and flexion knee was evaluated. In the same exercises, rate of force development at different time intervals was measured. Finally, functional capacity was assessed. Results: All trainings promoted similar improvements in the rate of force develpment of extension (effect size RFD 50 ms: 1 × 30 s .49, 3 × 10 s .67, 1 × 10 s .65; ES RFD 100 ms: 1 × 30 s .76, 3 × 10 s .80, 1 × 10 s .63; ES RFD 250 ms: 1 × 30 s .31, 3 × 10 s .49, 1 × 10 s .37) and flexion knee (ES RFD 50 ms: 1 × 30 s .59, 3 × 10 s .31, 1 × 10 s .48; ES RFD 100 ms: 1 × 30 s .41, 3 × 10 s .44, 1 × 10 s .42; ES RFD 250 ms: 1 × 30 s .57, 3 × 10 s .36, 1 × 10 s .43; ES RFD maximal: 1 × 30 s .63, 3 × 10 s .23, 1 × 10 s .26), however only the 3 × 10 s group improved the performance in the 8-foot up-and-go test (ES 3 × 10 s: .93, 1 × 30: .39, 1 × 10 s: .23). There was a maintenance of the isometric force and neuromuscular activity, except for the activity of the rectus femoris that showed an increase after training in all groups (ES 3 × 10 s: .04, 1 × 30: .36, 1 × 10 s: .50). Conclusion: Water-based resistance training using simple or multiple sets promotes the same gains in rapid strength, however only multiple sets induced improvement on functional capacity.  相似文献
