Young people's behaviours which are problematic to parents and therapists are also found in the wider adult community. Here these behaviours are often accepted as normal and legitimate, and as such they may occur even in the lives of these same parents and therapists. This paper considers some of the issues this raises in working with young people and their families. 相似文献

A close look at the income flows in the years following a divorce or separation reveals marked differences in the distribution of effects. The economic consequences of divorce are especially adverse for women. In most cases, children remain with the mother, who usually has considerably lower potential labor market earnings than her former husband, partly because her responsibilities for the children are likely to reduce her labor supply and may have limited her past human capital investments. Alimony and child support are the principal mechanisms for transfers from the ex-husband to the ex-wife, but payments are rarely frequent or sizeable enough to make up for an appreciable amount of the labor income lost through the departure of the ex-husband. Human capital investments on the part of the mother have a modest effect on her economic situation in the years following the divorce. Most men who divorce or separate are immediately better off because they retain most of their labor incomes, typically do not pay large amounts of alimony and child support to their ex-wives, and no longer have to provide for the level of needs associated with their former families. Much more important than growth in the ex-wife's own labor income is the role of a new husband's labor income upon her remarriage. More than half of the white women remarry within five years following a divorce or separation; the comparable fraction for black women is less than half. An interesting question is whether the currently unmarried would enjoy the same kind of economic benefits, were they to remarry, as women who have remarried. Estimates from a model of the new husband's labor income, adjusted for selection bias inherent in the process of remarriage, indicate that the currently unmarried would probably not gain equal benefits if they were to remarry. The expected labor income of potential husbands of black women averages only about $5000--a modest amount when compared with the alternatives available to these women. 相似文献

The method of first differences as an approach to modeling change is described and it is compared to more conventional two-wave panel models. Substantial advantages are found to the first-difference approach, especially if there are unmeasured, unchanging predictor variables in the model. It is also argued that there are substantial problems in the interpretation of results from the conventional two-wave models. Some of the analytic results are illustrated with a number of applications to the area of stressful life events. 相似文献

A key thrust of labour market policy in Australia and many other western countries is that long‐term unemployed people lack the personal motivation to engage proactively and successfully in the search for paid employment. In this paper we argue that the implementation of what are experienced as paternal workfare programs are counter‐productive to achieving the official policy goal of improving self‐efficacy and gaining paid employment. The empirical discussion presented in the paper is based on a semi‐longitudinal study that tracked 75 long‐term unemployed people in three different labour markets in Australia between 2005–2007. The study was funded by the Australian Research Council and Jobs Australia. 相似文献

This paper develops a statistically principled approach to kernel density estimation on a network of lines, such as a road network. Existing heuristic techniques are reviewed, and their weaknesses are identified. The correct analogue of the Gaussian kernel is the ‘heat kernel’, the occupation density of Brownian motion on the network. The corresponding kernel estimator satisfies the classical time‐dependent heat equation on the network. This ‘diffusion estimator’ has good statistical properties that follow from the heat equation. It is mathematically similar to an existing heuristic technique, in that both can be expressed as sums over paths in the network. However, the diffusion estimate is an infinite sum, which cannot be evaluated using existing algorithms. Instead, the diffusion estimate can be computed rapidly by numerically solving the time‐dependent heat equation on the network. This also enables bandwidth selection using cross‐validation. The diffusion estimate with automatically selected bandwidth is demonstrated on road accident data. 相似文献
