In 2006, the Australian parliament introduced new family law legislation about substantively shared overnight parenting arrangements between divorced couples. Other countries and state legislatures are currently debating the merits of similar legislation. A largely unquestionable premise underpins this reform, namely that the majority of children from separated families demonstrably benefit from the ongoing, warm and available involvement of both parents, in a climate of well-managed interparental conflict. The Australian legislation moves beyond encouragement of shared parenting in divorce cases with adequately functioning parents; it extends into grey areas which, to date, remain poorly serviced by credible research, including its application to children of all ages and to parents experiencing significant levels of ongoing conflict. Drawing on data from a longitudinal high-conflict divorce sample, this article challenges three assumptions that underpin a legislative preference for shared parenting, that shared parenting is viable and sustainable for divorced parents in conflict, that shared care enables improved cooperation between parents, and that as a result children will be less affected by their parents' conflict. The article further explores the influence of the mediation process on the choice and durability of shared parenting arrangements. 相似文献

大量的基层调查表明,农村中因父母外出打工而留守在家的“留守儿童”与同龄儿童相比存在着较为明显的行为、情绪、人格等方面的心理健康问题,并且依然有恶化的趋势。这些问题虽然尚不足以导致具有临床意义的心理障碍,但已影响到这些孩子健康成长。对此,一些学者和各地有关机构也提出并开始采取一系列措施进行心理干预,但从系统性、有效性和可操作性上看还缺乏说服力。基于对学校功能的认识和运用,应进一步探讨如何利用和拓展学校已有的教育功能(教育目标设置、教学管理、学生管理、师资建设和少团组织),来干预留守儿童的心理健康问题。 相似文献

Abstract: In this study, the accuracy of three methods for stature estimation of children from long bone lengths was investigated. The sample utilized consists of nine identified immature skeletons (seven males and two females) of known cadaver length, aged between 1 and 14 years old. Results show that stature (cadaver length) is consistently underestimated by all three methods (from a minimum of 2.9 cm to a maximum of 19.3 cm). The femur/stature ratio provided the least accurate estimates of stature, and predictions were not significantly improved by the other two methods. Differences between true and estimated stature were also greatest when using the length of lower limb bones. Given that the study sample children grew in less than optimal environmental conditions, compared with the children that contributed to the development of the methods, they are stunted and have proportionally shorter legs. This suggests that stature estimation methods are not universally applicable and that environmental differences within a population (e.g., socioeconomic status differences) or differing levels of modernization and social and economic development between nations are an important source of variation in stature and body proportions of children. The fallibility of stature estimation methods, when they do not consider such variation, can be somewhat minimized if stature is estimated from the length of upper limb bones. 相似文献

Abstract: The identification of aged latent fingerprints is often difficult, especially for those of children. To understand this phenomenon, the chemical composition of children’s versus adults’ latent fingerprints was examined over time using Fourier transform infrared microscopy. Hierarchical cluster analysis revealed that children’s and adults’ prints were distinguishable for up to 4 weeks after deposition, based on differences in sebum composition. Specifically, adults had a higher lipid content than children, but both decreased over time, attributable to the volatility of free fatty acids. The aliphatic CH3, aliphatic CH2, and carbonyl ester compositions changed differently in adults versus children over time, consistent with higher cholesterol and cholesteryl esters in children’s prints and wax esters and glycerides in adults’ prints. Thus, fingerprint composition changes with time differently in children versus adults, making it a sensitive metric to estimate the age of an individual, especially when the age of the print is known. 相似文献

This article begins with a discussion about the importance of ensuring that all children have lawyers in abuse and neglect cases. Lawyers provide a vital role in giving youth a voice in proceedings that sound profoundly affect their lives. The article then discusses why the client‐directed lawyer's role is consistent with federal law and legal ethics. Finally, the article discusses the growing support for client‐directed representation and what the American Bar Association has done to support this type of child representation. 相似文献

农民进城务工、经商己经成为我国解决"三农问题"的有效措施,也是我国城市化发展的根本要求。流动人口的子女在城市不能享受同等的教育机会,所以他们中的大部分不得不把孩子留在老家,从而形成"留守儿童"群体,成为违法犯罪的高发人群。"留守儿童"违法犯罪有社会因素、家庭因素和个体因素等多方面原因。 相似文献

Current models of neighborhood effects on victimization predominantly assume that residential neighborhoods function independent of their surroundings. Yet, a surprising proportion of violence occurs outside of victims’ residential neighborhoods. The current study extends on recent advances in spatial dynamics and neighborhood effects to explore the importance of different geographic scales and relational exposures to poverty for child violent victimization. We examine longitudinal data on over 4400 low-income children from high poverty neighborhoods in five cities, who participated in the Moving to Opportunity randomized intervention. The results suggest that surrounding poverty matters for child victimization beyond the effect of residential poverty. Moreover, moving farther from extreme poverty also seems to buffer against victimization and to amplify the benefits of moving to improved extended (residential and surrounding) neighborhoods. All the children in the study, but especially boys older than 10 years of age, seemed to be affected by the long arm of poverty. 相似文献

Despite increased interest in child abuse and neglect in the past decade, little research attention has been focused on maltreatment in handicapped populations. This is surprising given that many handicapped children display characteristics (e.g., chronic and pervasive behavioral disturbances, decreased social initiations with caregivers) that are associated with high risk for assault and neglect in nonhandicapped children. Numerous investigations have found an overrepresentation of handicapped children in maltreated samples, and results of more recent efforts reveal a high incidence of abuse and neglect in handicapped populations. Although these data underscore the high risk for maltreatment in handicapped children, a number of important issues warrant further empirical examination. Moreover, generalizations and interpretations of findings from previous research have been obfuscated by methodological shortcomings. The present paper reviews the literature concerning abuse and neglect of handicapped children. Research strategies and issues are delineated and current problems in this field are discussed. Suggestions for directions future research might take are offered. 相似文献

The hypothesis that children's appraisals mediate the relationship between interparental violence and adjustment was tested in a sample of 106 maritally violent families. Multiple regressions showed that interparental violence was a predictor of total problems, externalizing, internalizing, and anxiety for boys, and total problems and internalizing for girls. Appraisals of conflict properties mediated the relationship between violence and boys' total problems and externalizing, and girls' total problems and internalizing. Interparental violence was related to appraisals in gender-differentiated ways, particularly to increased threat for boys, and self-blame for girls. Further, threat mediated the impact of violence on boys' anxiety, while self-blame mediated the relationship between violence and girls' internalizing. 相似文献
