The aim was to identify genetic and environmental influences on the covariances between subjective well-being (SWB), perceived health, and somatic illness. Analyses were based on 6576 Norwegian twins aged 18-31. Heritabilities ranged from .24 to.66. SWB correlated .50 with perceived health, -.25 with musculoskeletal pain, and -.07 with allergy. Common genetic factors accounted for 45%-60% of associations. SWB and perceived health was to a high extent influenced by the same genes (r(g)=.72 and.82 for males and females, respectively). For SWB and musculoskeletal pain, r-sub(g) =-.29 and -.42 for males and females, respectively. Effects were partly sex specific. Environmental factors shared by twins did not affect the covariances. Results support a differentiated view of SWB-health relations, and imply that both genes and environment play important roles in the associations between well-being and health. 相似文献

The effects of sex (rater and ratee) on raters' accountability in the context of performance appraisal were investigated. The 130 participating undergraduates (men and women) rated a fictitious male or female's performance on a clerical task subsequent to receiving self-assessment information. As expected, raters' knowledge of a high self-assessment was followed by significantly higher performance ratings than after knowledge of a low self-assessment. Contrary to expectations, no differences were found for either raters' or ratees' sex. The results suggest that the sex of the rater or ratee is not associated with raters' accountability. 相似文献

We have used a combined genetic and pharmacological approach to define the time course of the requirement for protein kinase A (PKA) and protein synthesis in long-term memory for contextual fear conditioning in mice. The time course of amnesia in transgenic mice that express R(AB) and have genetically reduced PKA activity in the hippocampus parallels that observed both in mice treated with inhibitors of PKA and mice treated with inhibitors of protein synthesis. This PKA- and protein synthesis-dependent memory develops between 1 hr and 3 hr after training. By injecting the protein synthesis inhibitor anisomycin or the PKA inhibitor Rp-cAMPs at various times after training, we find that depending on the nature of training, contextual memory has either one or two brief consolidation periods requiring synthesis of new proteins, and each of these also requires PKA. Weak training shows two time periods of sensitivity to inhibitors of protein synthesis and PKA, whereas stronger training exhibits only one. These studies underscore the parallel dependence of long-term contextual memory on protein synthesis and PKA and suggest that different training protocols may recruit a common signaling pathway in distinct ways. 相似文献

This paper reviews evidence that behavioral family interventions are effective at improving child-rearing in distressed families and families with children exhibiting disruptive behavior. Essential therapeutic strategies offered within a collaborative therapeutic process are identified. Exemplary materials for parents and clinicians are identified. Differences between behavioral family interventions and two popular press parenting approaches are highlighted, including the lack of empirical support for these widely used programs and the advice they offer which runs counter to behavioral approaches. Recommendations are offered for combining behavioral family interventions with other empirically supported approaches, promoting more widespread use of empirically supported treatments, such as behavioral family interventions, and the need for a public health perspective on family functioning, involving collaboration among clinicians, policy makers, and researchers. 相似文献

Fragile families are defined as those that include unmarried or romantically unstable parents who have children and are socioeconomically disadvantaged. Mothers in fragile families may experience risk factors that lead to increased depressive symptoms that inhibit their ability to bounce back after stressful events. Risk factors for poorer maternal mental health may include declines in father involvement and a lack of coparenting support. This study examined the connected nature of coparenting and father involvement over time among continuously unmarried mothers from the Fragile Families and Child Wellbeing Study. A bidirectional latent growth curve analysis demonstrated that early father involvement was associated with a more gradual decline in coparenting support over the child's first 5 years, while early coparenting support also predicted a slower decline in father involvement over time. Steeper declines in coparenting support and father involvement over time were linked with more maternal depression and lower maternal life satisfaction when their child was nine. Results demonstrate a clear need for targeted intervention with both parents in fragile families to promote involved fathering behavior and enhance coparental relationships. 相似文献

This article summarizes research that challenges conventional wisdom about the early roots of marital distress and divorce. We abstract results from a 13-year study that focused on the extent to which long-term marital satisfaction and stability could be forecast from newlywed and early marital data. We explore the usefulness of three models emergent distress, enduring dynamics, and disillusionment designed to explain why some marriages thrive and others fail. The dominant paradigm, the emergent-distress model, sees newlyweds as homogeneously blissful and posits that distress develops as disagreements and negativity escalate, ultimately leading some couples to divorce. The results we summarize run counter to this model and suggest instead that (a) newlyweds differ considerably in the intensity of both their romance and the negativity of their behavior toward one another and, for those who remain married, these early dynamics persist over time; and (b) for couples who divorce, romance seems to deteriorate differently depending on how long the marriage lasts. Soon after their wedding, "early exiters" seem to lose hope of improving an unpromising relationship; "delayed-action divorcers" begin marriage on a particularly high note, yet quickly show signs of disillusionment. These delayed-action divorcers reluctantly give up on the marriage long after the romance has faded. 相似文献

Paul Tillich's eternal now is the ground from which all things emerge and perish in each and every moment. A Tillichean eschatology involves the gathering of all things finite into the eternity of the present moment, into God. Salvation is present moment. But is the “eternal now” enough? This essay offers biblical and theological critiques of Tillich's present eschatology and posits an eschatology that combines Tillich's “eternal now” with Wolfhart Pannenberg's “end‐oriented eschatology.” The result is an eschatology that recognizes the eternal now in which all things (including all time) belong to God yet with an eye toward the God‐given possibilities of the next moment, the future. The end of being is not cessation; rather, it is the fulfillment of time, the consummation of all things. 相似文献
