Psychosocial perspectives on children’s development are allied to theories that recognize the ‘self’ as essentially a social entity. The quality of relationships that children experience in their social environment have a profound effect on their socio-emotional development, personality formation and social competence. To this extent, psychosocial theories of children’s development and wellbeing can provide child and family social workers with a powerful framework within which to analyse, assess and practise. However, it is also recognized that the character of child welfare practices and policies are influenced by prevailing political climates. A simple dichotomy is described between political philosophies of the right and left; libertarianism and communitarianism; individual freedom and collective action. It is argued that the present swing to libertarian individualism has brought about major changes in the policy and practice of much child and family social work, including a preference for theories that emphasize people’s psychological independence, rationality and personal responsibility. In such a climate, child and family social work becomes more legalistic, orientated towards principles of justice rather than welfare, and towards rights and responsibilities rather than personal relationships and social competence. Psychosocial developmental theories, with their emphasis on the importance of social relationships and the emotional interconnectedness of people in community, fare less well under the rigours of psychological individualism and free-market economics. The paper concludes that if children’s psychosocial development and competence are a product of their social history, practices that psychologically ‘disembed’ people from their relationship environment are unable to consider children’s needs within a coherent, well-grounded theoretical framework. If child and family social work is premised on helping children develop social understanding and emotional wellbeing, theory and practice are best served by taking a psychosocial perspective.  相似文献

Sources of power children use in sibling conflict during early and middle childhood were examined according to French and Raven's typology of power. Participants included 66 dyads with an older (M = 81.8 months, SD = 14.48 months) and younger (M = 56.2 months, SD = 13.03 months) sibling. Data based upon naturalistic observations were coded for conflict issues (object, procedure, and information), power types (coercive, information, and legitimate), power effectiveness (attempts and successes), and resolutions (win/lose and compromise). Siblings used coercive power in object issues and information power in procedural issues. Whereas younger siblings used legitimate power in procedural and object issues including win/lose and compromise outcomes, older siblings used coercive power in win/lose resolutions. Siblings did not differ in their effectiveness of power, but they were most effective when coercive power was employed. Findings are discussed in light of power theory and the development of conflict management skills.  相似文献

The traditional mixture model assumes that a dataset is composed of several populations of Gaussian distributions. In real life, however, data often do not fit the restrictions of normality very well. It is likely that data from a single population exhibiting either asymmetrical or heavy-tail behavior could be erroneously modeled as two populations, resulting in suboptimal decisions. To avoid these pitfalls, we generalize the mixture model using adaptive kernel density estimators. Because kernel density estimators enforce no functional form, we can adapt to non-normal asymmetric, kurtotic, and tail characteristics in each population independently. This, in effect, robustifies mixture modeling. We adapt two computational algorithms, genetic algorithm with regularized Mahalanobis distance and genetic expectation maximization algorithm, to optimize the kernel mixture model (KMM) and use results from robust estimation theory in order to data-adaptively regularize both. Finally, we likewise extend the information criterion ICOMP to score the KMM. We use these tools to simultaneously select the best mixture model and classify all observations without making any subjective decisions. The performance of the KMM is demonstrated on two medical datasets; in both cases, we recover the clinically determined group structure and substantially improve patient classification rates over the Gaussian mixture model.  相似文献

A new mathematical dose-response model for reproductive and developmental risk assessment is proposed. The model includes the possibility of an exposure threshold as well as a litter-size effect. Correlation of responses of offspring from the same litter is taken into account through the use of the beta-binomial distribution. Confidence limits for low-dose extrapolation are based on the asymptotic distribution of the likelihood ratio. An empirical comparison of the proposed procedure to that of Rai and Van Ryzin demonstrates the improvement that can be achieved with the new procedure.  相似文献

The present approach to welfare reform, as embodied in the Final Report of the Reference Croup on Welfare Reform (2000), relies heavily on the rhetoric of ‘mutual obligation’ and ‘welfare dependency’ while placing Utile emphasis on original research and relevant data that might inform and support its reform agenda. In marked contrast are the research‐driven policy processes aimed at the alleviation of child poverty that took place during the Hawke‐Keating government in the late 1980s, in this paper we illustrate the value of research in relation to two government strategies, the Family Allowance Supplement (FAS) and the Child Support Scheme (CSS), that were instrumental in bringing a significant number of children out of poverty. We suggest that any commitment to further the reduction of child poverty requires resources for ongoing research programs.  相似文献

Imitation is argued to have an important affiliative function in social relationships. However, children's tendency to imitate different play partners during naturalistic play and associations with social understanding have been overlooked. We investigated the frequency and context of imitation in a longitudinal study of 65 focal children (T1: M age = 56.4 months, SD = 5.71) during play with their older or younger sibling and a friend in two separate play sessions. Children were observed again approximately 3 years later (T2: n = 46, M age = 94.6 months; SD = 6.6). We coded focal children's verbal and nonverbal imitation of their play partner, their partner's response to being imitated, the context in which imitation occurred (e.g., pretense), and the focal child's social understanding (i.e., mental state references). Verbal imitation occurred more often than nonverbal imitation and was used most often during the contexts of play negotiations and pretense. Although focal children's imitation of both their siblings and friends increased significantly over time, children imitated friends more than siblings at T1. All play partners responded positively (i.e., smiling, laughing) most often to being imitated. Associations between focal child imitation and mental state talk with friends at T2 approached significance. Our findings provide a deeper understanding of the nature of imitation during children's play interactions and support assertions that imitation is a process whereby children build affiliation, mutuality, and shared meanings in their relationships.  相似文献

Improving the standardization and efficiency of adult protective services (APS) investigations is a top priority in APS practice. Using data from the Elder Abuse Decision Support System (EADSS), we developed short-form measures of four types of elder abuse: financial, emotional/psychological, physical, and neglect. The EADSS data set contains 948 elder abuse cases (age 60+) with yes/no abuse substantiation decisions for each abuse type following a 30-day investigation. Item sensitivity/specificity analyses were conducted on long-form items with the substantiation decision for each abuse type as the criterion. Validity was further tested using receiver–operator characteristic (ROC) curve analysis, correlation with long forms and internal consistency. The four resulting short-form measures, containing 36 of the 82 original items, have validity similar to the original long forms. These short forms can be used to standardize and increase efficiency of APS investigations, and may also offer researchers new options for brief elder abuse assessments.  相似文献

Child protection work is complex and demanding and presents both parents and workers with a number of emotional and relationship demands. Although it is recognised that a good working alliance between child protection workers and parents is associated with therapeutic success and service user satisfaction, some current developments, including the growth of an audit culture with its attendant emphasis on targets and performance, appear to undermine the worker's ability to establish good relationships and working alliances. To the extent that poor‐quality working relationships and increased emotional distance reduce the worker's capacity to be empathic, levels of stress for both parents and workers are likely to remain high. Heightened stress reduces the capacity of parents and workers to keep at‐risk children in mind and in focus. This reduces their safety. The paper revisits the value of containment as a way of processing and managing difficult feelings which, along with more recent therapeutic concepts such as mentalisation, encourages workers to keep the parents' feelings in mind as well as hold the child in mind for the parent as a psychological, meaningful and mentalising being. Helping parents think about their feelings and understand, indeed celebrate, their children as burgeoning, independent psychological entities increases understanding, reduces stress and plays a part in helping keep children safe.
