Unwanted sexual attention (UWSA) encompasses unsolicited verbal comments, gestures, stares, and other noncontact behaviors made regarding one's sexuality and physical appearance. The present study examined the correlates and impact of such UWSA perpetrated toward girls by family members. The first objective of the study was to explore whether family climate is associated with intrafamilial UWSA. This included looking at three types of dysfunctional parenting styles (unaffectionate, unavailable, and patriarchal) as well as exploring the co-occurrence of UWSA by adult and child relatives. The second objective was to then measure the impact of such intrafamilial UWSA on childhood emotional health, after controlling for parenting style and the experience of more traditional forms of child sexual abuse (CSA). Of the 296 university women (mean age = 19) who participated in the study, 70% (N = 206) reported UWSA from a family member prior to age 18. Whereas each dysfunctional parenting style was related to presence of UWSA, a simultaneous multiple regression analysis indicated that two of the parenting styles, patriarchal and parental unavailability, also predicted frequency of nonphysical UWSA within the family. Presence of UWSA from a child relative was significantly correlated with presence of UWSA from an adult relative. Additionally, a hierarchical multiple regression, entering the three parenting styles simultaneously in the first step, childhood sexual abuse in the second step, and familial UWSA in the last step, indicated that the frequency of UWSA by family members significantly predicted poorer childhood mental health when controlling for the other variables. Overall, results indicate that while the specific parenting styles which co-occur with UWSA may be detrimental in their own right, the impact of UWSA on girls appears to be above and beyond that of either parenting styles or CSA. Clinical implications are discussed. 相似文献

This article summarizes some of the literature reviewed by the Girls Study Group, which is a federally funded project aimed at assessing the causes of girls’ delinquency as well as evaluating programs to address it. The literature reveals that a number of factors such as family dysfunction, involvement with antisocial peers, and living in disadvantaged neighborhoods are correlated with delinquency for both boys and girls. Some factors, however, are gender sensitive, meaning that either girls are more exposed to a given risk factor than boys or react somewhat differently to a given risk factor. Girls have higher rates of exposure to sexual assault, which is associated with delinquency and, although more research is needed, they are more affected by the impacts of early puberty, when it is coupled with harsh parenting and disadvantaged neighborhoods. This article discusses some implications of the research on correlates of delinquency for programming for girls and makes recommendations for program selection. 相似文献

The American Law Institute proposes that in contested physical custody cases the court should allocate to each parent a proportion of the child's time that approximates the proportion of time each has spent performing caretaking functions in the past. Examined through the lens of child development research, the approximation rule is unlikely to improve on the best interests standard. It is difficult to apply; is perceived as gender‐biased; creates a new focus for disputing parents; renders a poor estimate of parents’ contributions to their child's best interests; overlooks parents’ intangible, yet significant, contributions to their child's well‐being; and miscalculates the essence of how a child experiences the family. A preferable alternative is a better defined, contemporary best interests standard that accommodates new knowledge and reforms that encourage nonadversarial, individualized resolutions of custody disputes. 相似文献

Data on bone tissue fractography are summarized and systematized. Possibilities of a microscopic fractography method in analysis of skeletal bone fractures in order to determine conditions of traumatic exposure were shown. Destruction of bone tissue is considered from the point of view of fragile and tough destruction using as a model solid body with crack at the top of which deformations of detachment, lateral and longitudinal shifts are acting. Morphologic features for different types of destruction were singled out. Use of these features may help to determine character and type of deformation at concrete areas of fracture during all destruction process. 相似文献

Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce. 相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning. 相似文献

Archibald T. Strong, born in Melbourne, was the son of an Australian scholar who went to an academic post at Liverpool. The younger Strong received his secondary and tertiary education in England. There, he became proficient in modern European languages and literature. He initially planned a career in the law, but for health reasons returned to Australia to the Department of English at the University of Melbourne. Prior to the First World War, Strong became prominent in Melbourne literary circles and also a prolific commentator on world affairs. As an early member of the Round Table group in Australia, Strong assessed Imperial Germany as posing an existential threat to the British Empire and hence to Australia's security. The nation's future, he believed, lay in unwavering defence of the Empire. Strong evinced a distinct impatience with fellow citizens, especially on the socialist left, who failed, in his view, to understand the realities of Australia's position in the world and what was at stake in the Great War. 相似文献
