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62.

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

Perceptions regarding open science appraised by editors of scholarly publications published in Spain

Pillars of open science are often included within the editorial policies of scholarly journals, including policies on open access publication, availability of underlying research data, preprints and open peer review. The aim of this paper is to examine and analyse perceptions and editorial practices related to open access, preprints, open research data and open peer review, from the perspective of editors of scientific journals published in Spain, to gain an insight into editorial policies related to open science. Results and data were obtained by a combined method of online interviews and an online questionnaire. The online survey was sent to editors from journals indexed in the Dulcinea directory, which at the time of the study included 1875 academic journals. A total of 420 responses (22.4%) were obtained. The results indicated that 92% of the journals were open access journals, 2% of the journals conducted open peer review, 15% of the journals had instructions to allow archiving preprints, and out of 375 responses, only 59 journals (16%) reported having a policy on underlying research data. Based on these results, there is a trend in favour of open access, but the perceived barriers to open peer review outweighed the advantages. There is also some reluctance to allow preprints to be made available. This concern might be because editors want authors and readers to read and cite the contents published in their journals, rather than their preprint versions. 相似文献

Anatomical dissection on cadavers can be a source of anxiety for medical students. Studies in other stressful settings have shown a reduction in anxiety when there is background music. The objective of this study was to determine if music can have an impact on student anxiety, student satisfaction, and student performance in dissection room. This cluster randomized interventional trial included 187 second-year medical students. The intervention was standardized background music, selected based on the literature, with a tempo of between 60 and 80 bpm. Six balanced clusters were randomized (1:1) to music or no music during dissection sessions. The main assessment criterion was a validated self-evaluation scale score for anxiety, the State Trait Anxiety Inventory. Student satisfaction was measured using a visual analog scale and dissection performance was evaluated by an examination. The outcomes were analyzed with mixed models adjusted on group effect, chronic anxiety, and confounding factors. A significant (58%) relative decrease in acute anxiety, odds ratio 0.423 [0.160; 0.710] was found for the music intervention group. Music also had a positive impact on performance with students in the intervention group attaining higher grades than those in the control group (0.42/10 higher, P = 0.0016). The study also showed a nonsignificant increase in satisfaction with 0.37 extra points (P = 0.137) in the intervention group. Background music had a significant impact on anxiety in the dissection room and on technical and theoretical performance in the subsequent anatomy examination. This music intervention could be extended to other stressful work environments. 相似文献

This paper analyzes the singularity of artistic cultural sector workers in the Brazilian metropolitan labor market, considering the job satisfaction of artists that Throsby proposes in his work preference model of artist behavior (1994). We also examine the effect of public expenditures on the income of workers in the cultural sector. Using 2002 to 2010 data from the Monthly Employment Survey (PME) and administrative records from Finance of Brazil (FINBRA), we estimate a probit model and a wage equation. In our model, we estimate wages as a function of: (1) sociodemographic characteristics of workers, (2) a variable for informal jobs, (3) the number of working hours, (4) a variable for the worker having another job, (5) per capita expenditures on culture interacted with a dummy for artistic cultural workers, (6) interactive binary variables involving place of residence and artistic cultural workers and (7) the predicted probability obtained by the probit model. This probability is estimated based on the likelihood of working in a creative activity, considering both workers from the cultural sector and other workers, controlled by: (1) sociodemographic characteristics of workers, (2) characteristics of their jobs, (3) dummies for the metropolitan regions and (4) willingness of creative workers to work additional hours interacted with the number of hours worked. Our results show that workers in the cultural sector are likely to work longer hours when compared to workers in other sectors. For our wage equation, the results suggest that women earn relatively less than men and blacks earn less than whites. Furthermore, earnings increase with age and the level of education. Formal workers obtain higher earnings when compared to informal ones. Finally, an increase in the per capita public expenditure on the cultural sector raises the income of workers in artistic cultural occupations. 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
