This research examined whether heightened neural activation to social cues confers adjustment advantages in supportive social contexts but adjustment disadvantages in stressful social contexts. Forty‐five adolescent girls were exposed to social exclusion during an fMRI scan and reported on parent–child relationship quality and depressive symptoms. Stressful parent–child relationships predicted subsequent depressive symptoms in girls with high and moderate but not low dorsal anterior cingulate cortex, subgenual anterior cingulate cortex, and anterior insula activation during exclusion. In the context of supportive parent–child relationships, however, neural activation to exclusion predicted particularly low levels of depressive symptoms. This support for a biological sensitivity to context model suggests the possibility of redirecting adolescent girls’ neural sensitivity to social cues toward more positive adaptation. 相似文献

Adolescents are more susceptible to dysregulation in positive social contexts, compared to children. We investigated whether maternal presence would buffer these effects in adolescence. Fifty‐four adolescents and children (age range = 8–17 years, Mage = 13.38 years) completed a social go‐nogo task during an fMRI scan alone and in the presence of their mother. We found age‐related patterns, such that older relative to younger youth displayed more disinhibition toward socially appetitive than socially aversive stimuli, which was buffered by maternal presence. Furthermore, with age, maternal buffering in socially appetitive contexts elicited heightened activation in the ventromedial prefrontal cortex and amygdala–medial prefrontal cortex connectivity. Findings underscore the importance of caregivers in promoting the neural regulation of their offspring during adolescence. 相似文献

Neuroimaging work has examined neural processes underlying risk taking in adolescence, yet predominantly in low‐risk youth. To determine whether we can extrapolate from current neurobiological models, this functional magnetic resonance imaging study investigated risk taking and peer effects in youth with conduct problems (CP; N = 19) and typically developing youth (TD; N = 25). Results revealed higher real‐life risk taking, lower risky decisions, and no peer effects on a risk‐taking task in CP youth. CP youth showed greater ventral striatum (VS) activity during safe than risky decisions, whereas TD youth showed greater VS activation during risky decisions. Differential VS activity explained higher real‐life risk taking in CP youth. Findings provide preliminary evidence that risk‐taking behavior in youth with CD problems is characterized by differential neural patterns. 相似文献

Little is known about over 125,000 veterans who received non-honorable military discharges since 2001, even though these veterans face substantial barriers to obtaining services and are likely to be at high risk for negative mental and behavioral health outcomes including suicide. Seven-hundred twenty-two veterans living the in the San Francisco Bay Area participated in the study. The sample comprised honorably discharged (n = 508) and non-honorably discharged veterans (n = 214). T-tests were used to compare means on predictors of suicide risk including Posttraumatic Stress Disorder (PTSD), depression, alcohol use, somatic symptoms, and physical disability. A series of regression models tested relationships between predictors, discharge status, and suicide risk. Non-honorably discharged veterans demonstrated higher mean scores than honorably discharged veterans on all predictors. In regression models, somatic symptoms (β = 0.22, p < 0.001), physical disability (β = 0.16, p < 0.05), and discharge status (β = 0.33, p < 0.001) were associated with suicide risk. The final model showed an interaction effect for discharge status on the relationship between somatic symptoms and suicide risk (β = 0.16, p < 0.05). Non-honorably discharged veterans showed higher rates of mental and physical health problems and suicide risk compared to honorably discharged veterans. The magnitude of the relationship between somatic symptoms and suicide risk was significantly greater in non-honorably discharged veterans. 相似文献

BackgroundIn Norway pregnant women who are not regarded to be in a risk group are offered one routine ultrasound around the 18th week of pregnancy. If serious abnormalities are diagnosed, the women may apply for a termination.Research QuestionThe aim of this study was to describe and understand some pregnant women's thoughts, feelings and dilemmas of choice when unexpected findings were diagnosed after a routine ultrasound examination.MethodsThis study was based on 22 semi-structured life world interviews. The women interviewed were informed of unexpected findings after undergoing routine ultrasound examinations around the 18th week of pregnancy. The analysis of the data was inspired by phenomenological research and followed the meaning condensation approach described by Kvale (1).ResultsThe informants’ experiences are presented by showing how they described shifts between juxtaposed emotional states: hope–acceptance, distancing–denial and grief–guilt. All of the informants described these swings between different emotions as a state of continuous chaos.DiscussionThe discovery of abnormality in a wanted child at a late stage of pregnancy can evoke an emotional crisis for women. All the informants in this study described swings between different emotions as being in a state of continuous chaos. The women had to make difficult choices regarding their own future and that of their child.ConclusionEliminating the anxiety and anguish experienced by women following a diagnosis of fetal abnormality is impossible. It must be possible, however, to mitigate their distress. Further research should develop methods to prepare women for coping in crises like these. 相似文献

Rationalizations generally have a negative effect on health and known risk factors for musculoskeletal disorders. These effects may be reduced by paying attention to modifiers as worker participation and a resonant management style. In this study a participatory approach was used in the food industry in order to improve ergonomics and productivity. The food industry shows a high prevalence of musculoskeletal disorders, and repetitive manual work occurs extensively. Prototypes of new packaging solutions were developed in three cases, and compared in a simulated production to the existing production system through direct measurements of working postures and muscle activity, ratings of physical load, and general productivity data. Measured and rated ergonomic exposures showed that workload was significantly lower for the prototypes, in all three cases. In two cases, the number of handling operations included in the packaging operations were greatly reduced with the prototype package, as were production costs. The impact on disorders of the obtained load reductions is difficult to assess, but we believe that in "critical" situations like this, even small improvements may have an effect. This study shows that workloads during manual handling of packages as well as production costs can be reduced by applying participative development of packages. 相似文献

In 2007–2008, the University of Nevada, Las Vegas Libraries conducted a large collection assessment project. The Collection Assessment Committee identified several possible ways to conduct the review, one of which was using reports from the link resolver SFX. The committee used several link resolver reports in conjunction with statistics from the Libraries' document delivery department to identify trends in journal usage among disciplines. The link resolver reports can help identify new journals for purchase and are useful for providing information on user behavior. 相似文献
