Paul V. Trad 《Child Abuse Review》1995,4(2):114-128
The incidence of pregnancy during adolescence has escalated dramatically in recent years, with an estimated half a million infants born to teenagers each year in the United States. A disproportionately high amount of child abuse and/or neglect is encountered among adolescent parents, underscoring the need for an effective intervention strategy. Short-term psychotherapy may be beneficial in these cases for forging a therapeutic alliance expeditiously and rigorously challenging the patient's resistance. The case described involves alleged abuse by a 16-year-old mother. An intervention was designed to clarify the allegations surrounding the abusive incident, help the mother confront episodes of loss in her own life and overcome feelings of hopelessness engendered by separation from her infant. 相似文献

寄生在同一个链条上的两害——乌鲁木齐市贩毒、吸毒人群与艾滋病人群的相关研究 总被引:1,自引:0,他引:1
新疆毗邻世界毒源重地"金新月"地区,特殊的地理位置为国际、国内大小毒枭所垂青,使其不仅是毒品的集散地,也是吸毒的重灾区。同时,当地的艾滋病疫情也不容小视。调查研究表明:乌鲁木齐(包括新疆)不是制毒的基地,而是"金新月"毒贩选定贩运毒品的重要通道;贩毒、吸毒、艾滋病,没有民族界限;贩毒———吸毒与艾滋病是同一链条上的两害,是当地艾滋病疫情的主要成因。 相似文献

The authors seek to give an overview of ways in which social indicators relevant to research on children affected by armed
conflict can be developed, and how such research can be carried out. Technical and methodological challenges involved in this
pursuit are discussed. It is argued that data production must consider issues of definition and delineation of the phenomenon
of war-affected children more actively than it does currently. An analytical approach is proposed, in which children’s characteristics
in different situations, or in different stages of conflict, may be used as intakes to understanding how the social processes
pertaining to life histories of children in armed conflict are created and reproduced.

There is a vast empirical literature investigating the effects of child care costson female employment. Day-care costs are usually treated as a reduction infemale wages and are supposed to reduce a woman's propensity to participatein the labor market. In this paper we argue that an analysis of the effects ofchild care on the employment of mothers in Germany should focus on theavailability rather than the affordability of care, due to peculiarities of theGerman day-care regime. Our empirical findings cast doubt on the effectivenessof the current German day-care regime. Specifically, we question the extent towhich it enables mothers to participate in the labor market. 相似文献

Each state has the power to establish its own policy and laws relating to child custody determination. The number of single-parent families with children that are headed by fathers has been growing in the United States. This paper explores the extent of cross-state variation in the prevalence in father-only families in 1990, and the extent to which there was cross-state variation in the increase in father-only families in the 1980s. The 1980 and 1990 Public Use Microdata Samples (PUMS) drawn from the US decennial censuses are used. Decomposition analyses of growth indicate that increases in the number of father-only families occurred across all states during this period, but at varying rates. The primary reason for the increase in most states is an increase in the proportion of ever-married single-parent families that are headed by a father. It is for these families that are headed by divorced or separated parents that state policy relating to child custody determination is most relevant. 相似文献

本文围绕一项针对上海市育龄女性的生育意愿调查,分别使用二分和有序Logit方法分析儿童照顾对上海市育龄女性的二孩生育意愿的影响。研究发现当育龄女性能够从家庭内和社会中获得更多孩子照料的时间支持时,她们有更高的二孩生育意愿,也会伴有更明确的二孩生育规划;双独家庭能够从父辈获得更多的经济、时间上的帮助,因此他们要比单独家庭和双非家庭更愿意再生一个孩子;居住于上海市城区的女性从某种程度上更易获得孩子的照料资源,有更多的优质教育资源可供选择,因此她们的二孩生育意愿高于居住于郊区的女性。此外,本文通过是否采用了避孕措施对二孩生育的意愿程度做了进一步区分,结果发现当第一个孩子主要是由孩子父母承担照料工作的时候,女性存在二孩生育意愿的程度是最低的,祖辈照料对二孩生育意愿程度的积极影响也明显低于社会性照料,此现象在上海市户籍的女性中体现尤为明显。最后为纠正自选择偏差问题,本文使用倾向值匹配方法(PSM)进一步验证了与首孩性别相比,首孩的抚养成本与接受照料情况显然对二孩生育意愿的影响程度更大。因此,本文认为加大公共托育服务的供给、为育龄女性提供高质量的0-3岁婴幼儿社会照料支持是提高二孩生育意愿的最有效... 相似文献

The situation of families undergoing separation in a context of co‐occurrence of intimate partner violence (IPV) and child maltreatment raises certain issues related to child custody. The results presented in this paper were collected and analysed within the framework of a qualitative study aiming to identify the principal points of agreement and the main controversies amongst practitioners in several different types of organizations. Focus groups were held with a total of 43 practitioners from six different settings concerned with child custody in cases of co‐occurrence of IPV and child maltreatment. Although they agreed on the importance of ensuring the safety of victims of violence, their views diverged on three points: (1) the importance of preserving the father–child relationship; (2) collaboration between voluntary organizations and semi‐voluntary or legal agencies; and (3) consideration of cultural differences. 相似文献

Summary. We consider the problem of obtaining population-based inference in the presence of missing data and outliers in the context of estimating the prevalence of obesity and body mass index measures from the 'Healthy for life' study. Identifying multiple outliers in a multivariate setting is problematic because of problems such as masking, in which groups of outliers inflate the covariance matrix in a fashion that prevents their identification when included, and swamping, in which outliers skew covariances in a fashion that makes non-outlying observations appear to be outliers. We develop a latent class model that assumes that each observation belongs to one of K unobserved latent classes, with each latent class having a distinct covariance matrix. We consider the latent class covariance matrix with the largest determinant to form an 'outlier class'. By separating the covariance matrix for the outliers from the covariance matrices for the remainder of the data, we avoid the problems of masking and swamping. As did Ghosh-Dastidar and Schafer, we use a multiple-imputation approach, which allows us simultaneously to conduct inference after removing cases that appear to be outliers and to promulgate uncertainty in the outlier status through the model inference. We extend the work of Ghosh-Dastidar and Schafer by embedding the outlier class in a larger mixture model, consider penalized likelihood and posterior predictive distributions to assess model choice and model fit, and develop the model in a fashion to account for the complex sample design. We also consider the repeated sampling properties of the multiple imputation removal of outliers. 相似文献
