This study assessed college men's ( n = 85) and women's ( n = 215) courtship persistence behaviors (approach, surveillance, intimidation, mild aggression), which have been linked to stalking, and examined their relations to initial courtship interest, relationship development, and future violence and persistence, while also exploring the role of gender in these relations. Findings showed individuals performed surveillance when initially more interested than the other. Whereas approach behaviors were positively associated with relationship establishment, surveillance and intimidation were negatively associated. As predicted, results showed continuity in persistence and violence over the course of dating relationships. For both genders, courtship mild aggression predicted relationship violence, and persistence behaviors predicted similar persistence at breakup. Early behaviors may foreshadow violence and stalking-related behaviors in both men and women.  相似文献

Despite widespread belief in the early childhood field of the benefits of reflective supervision, there has been limited empirical evidence to support the effectiveness of reflective supervision for home visitors and the children and families they serve. The present study examined the psychometric properties of four adapted self‐report measures assessing supervisors’ reflective supervision capacities; the study also investigated whether these measures captured change in reflective capacity over time as supervisors participated in professional development activities focused on reflective supervision. Results from 33 participants (home visiting supervisors and program managers) suggested that three of the four measures demonstrated acceptable internal consistency, and these three measures were correlated with each other. Two of these measures also captured significant change over time. Finally, there was some evidence that those with less education demonstrated more substantial improvement in their reflective supervision capacities than did those with an advanced degree. Findings provide initial evidence for reliable, efficient, and cost‐effective supervisor self‐report measures that could be used in research and program evaluation to assess change in supervisor reflective capacity over time.  相似文献

Opioid abuse is now considered an epidemic, and many of the adults using this substance are parents. The purpose of the current paper is twofold: (1) to review rigorously conducted studies (e.g., included a comparison group; utilized inferential statistics) examining the association of opioid abuse with parenting and child outcomes, and (2) to review parenting intervention programs with these caregivers. Findings indicate that there are very few rigorously conducted studies examining children and parenting when parents abuse opioids. Furthermore, only four intervention programs have been conducted using randomized control trials and inferential statistics. We conclude that there is limited research that can be labeled as a rigorous science currently addressing this aspect of the opioid epidemic. Recommendations for further research are delineated.  相似文献

Associations between uncoupling protein (UCP) expression and functional changes in myocardial mitochondrial bio-energetics have not been well studied during periods of starvation stress. Our aim was to study the effects of acute starvation, for 24 or 48 h, on combined cardiac mitochondrial function and UCP expression in mice. Isolated heart mitochondria from female mice starved for 48 h compared to that from mice fed revealed a significantly (p < 0.05) decreased adenosine diphosphate-to-oxygen ratio, a significantly increased proton leak and an increased GTP inhibition on palmitic acid-induced state 4 oxygen consumption (p < 0.05). These bio-energetic functional changes were associated with increases in mitochondrial UCP2 and UCP3 protein expression. In conclusion, our findings suggest that increased UCP2 and UCP3 levels may contribute to decreased myocardial mitochondrial bio-energetic function due to starvation.  相似文献
