The transition to first‐time parenthood can be challenging for couples. Using a sample of 848 ethnically diverse couples from the Fragile Families and Child Wellbeing Study across the first 3 years of parenthood, we investigated the longitudinal and dyadic associations of each parents’ parental stress, supportive coparenting, and relationship quality. Results from an actor–partner interdependence model indicated that supportive coparenting significantly predicted higher relationship quality for both mothers and fathers. Fathers’ supportive coparenting significantly buffered the effects of mothers’ parental stress on relationship quality. Also, the unique dyadic contexts of each parents’ supportive coparenting, and also both partners’ parental stress were significantly associated with relationship quality. Clinical implications from these findings are discussed through commonly used clinical theories.  相似文献

We examine how use of antidepressant medications is influenced by Food and Drug Administration (FDA) warnings about the increased risk of suicidality associated with pediatric antidepressant use. With individual-level data on antidepressant use from the Medical Expenditure Panel Survey, we consider whether consumer responses to FDA warnings differ among targeted (children) and non-targeted (adult) age-groups. Because the warning labels specifically mentioned new users, we examine separately the effects of the warnings on initiations of antidepressant therapy and on continued use of antidepressants. We find evidence consistent with reduced initiation of antidepressant use among the intended population of children, and that usage among children with more highly educated parents responded earlier to FDA information. However, we also find spillover effects of reduced initiation among the non-targeted population of adults. Overall, our results indicate that the FDA warning may have led consumers to perceive risks beyond those specifically mentioned.  相似文献

Despite the substantial amount of literature focusing on social support for pregnant and parenting adolescents, few studies have directly examined the relationships among stress and social support across their transition to parenting. The present study investigates the nature of the relationship between stress and support both before and after the birth of the baby. Two groups of adolescent females (one group facing parenthood and one not) completed measures of support and stress across a 7-month period (N = 231) to coincide with the transition to parenthood. In general, support and stress were negatively related when measured concurrently and positively related over time for parenting adolescents but not the non-parenting group. Understanding how long social support impacts stress will enable practitioners to identify when best to provide interventions for pregnant and parenting adolescents.  相似文献

The article describes an operational Bayesian approach to making inferences for the spectral density function for univariate autoregressive processes and for the AR operator of multivariate autoregressive processes. The derivation of the approach is described. Numerical examples, including the Wolfer Sunspot numbers, are used to demonstrate the practical usefulness of the approach.  相似文献

Urban forests and herbaceous open space play a vital role in the environmental and aesthetic health of cities, yet they are rarely identified in land-use inventories of urban areas. To provide information on urban forests and other vegetative land cover in Illinois cities, Landsat Thematic Mapper (TM) data from June 27, 1988, were classified for the Chicago metropolitan region (9,717 km2). Ten land-cover classes were identified, including two types of forestland (occupying 5.8% of the total area), residential land with trees (14.6%) or without trees (7.8%), cropland (37.5%), two types of grassland (7.7%), urban with impervious surfaces (23.1%), water (1.6%), and miscellaneous vegetation (2.1%). Correlation analyses indicated that household income and household density are strongly related to land covers in the region, particularly those with tree cover and urbanized land. Population changes for 1980–1985 and 1985–2010 (projected) show a pattern of increasing density in the urbanized zone concurrent with continued urban sprawl, primarily into current cropland.  相似文献

In addition to being held accountable for judicial decision, courts, like other public agencies, can and should be evaluated in terms of their administrative efficiency. This paper illustrates how courts can be evaluated in terms of their relative administrative efficiency, using a new approach—data envelopment analysis (DEA)—first proposed by Charnes et al. [1]. The DEA is based upon the economic notion of Pareto optimality which states that a given decision making unit (DMU) is inefficient if some other DMU, or some combination of other DMUs, can produce at least the same amounts of all outputs with less of some resource input and not more of any other resource. Conversely a DMU is said to be efficient if the above is not possible. Charnes et al. [1] generalized the usual input/output ratio measure of efficiency for a given unit in terms of a fractional linear program with fractional constraints. In the case of courts, the efficiency of any particular court is calculated by forming the ratio of a weighted sum of outputs to a weighted sum of inputs, where the weights for both outputs and inputs are to be selected in a manner that calculates the Pareto-Koopmans efficiency of the court. This paper reviews the DEA method and illustrates its application to a data base for 100 criminal superior courts in North Carolina.  相似文献

Mediating effects of social support on the link between childhood maltreatment and adult intimate partner violence (IPV) were explored in a sample of 362 low-income, African American women. We examined relations between childhood maltreatment experiences (total maltreatment, sexual abuse, physical abuse, emotional abuse, emotional neglect, and physical neglect) and adult maltreatment (physical IPV and nonphysical IPV). Results of hierarchical multiple regression analyses revealed small, but significant, effects. Further, social support mediated revictimization. Social support fully mediated relations in which the form of childhood maltreatment was different than the form of adult IPV (e.g., the relation between childhood sexual abuse and adult nonphysical IPV), but only partially mediated the relations in which the form of childhood maltreatment was similar to adult IPV (e.g., the relation between childhood emotional abuse and adult nonphysical IPV). Implications for clinical interventions for women with intimate partner violence experiences are discussed.  相似文献

This article examines how notions of "the child" were constructed in marketing research literature from the 1910s through the 1990s. Drawing on children's industry trade literature, market reports and books, I argue that children have become increasingly portrayed as individualized, autonomous consumers. Over this time period, the desire for consumer products becomes figured by industry observers and researchers as a mode of children's "self expression.'The analytic isolation of "the child" in the persona of a "consumer" authorizes a new morality for consumption by construing children's desire for goods as preexistent and thus natural.  相似文献

From 1890 to 1970 Australian women’s use of female-controlled birth control methods was higher than that of English women. The latter primarily depended upon withdrawal and condoms. Use of these male-controlled methods of contraception is associated with low levels of female sexual pleasure, and the belief that husbands should initiate sexual activity and should control their wives’ fertility. I argue that higher use of female methods gave white Australian women greater sexual and reproductive autonomy throughout this period. The view that they were in a less desirable position than women in other Anglo cultures needs to be examined more closely.  相似文献
