Some effects of the war on child placement work

Abstract

Studies of social work students reveal high rates of family dysfunction and trauma (Black, Jeffreys, &; Hartley, 1993; Rompf &; Royse, 1994; Russel, Gill, Coyne, &; Woody, 1993). Object relations theory (Hanna, 1990a, 1990b; Winnicott, 1965) and family systems theory (Lackie, 1983) explain how the choice of a helping profession motivated by unmet dependency needs may lead to problems in clinical performance. This article reports on an exploratory study (n = 15) that found some support for the theoretical link between a history of early, pervasive family caretak‐ing by second‐year clinical MSW students and Winnicott's False Self characteristics. Analysis of process recording data and Working Alliance Inventory (Horvath &; Greenberg, 1989) scores suggest some effects of this caretaking history on students’ clinical performance. Implications for social work education and practice are discussed.     

Assessment of Indoor Route-finding Technology for People with Visual Impairment

This study investigated navigation with route instructions generated by digital-map software and synthetic speech. Participants, either visually impaired or sighted wearing blind folds, successfully located rooms in an unfamiliar building. Users with visual impairment demonstrated better route-finding performance when the technology provided distance information in number of steps rather than walking time or number of feet.     

Sexual perceptions and practices of young people in Northern Thailand

This study draws together survey and qualitative data on sexual practices among more than 1,750 young Northern Thai people aged 17-20 years. The survey data indicate that sexually active young people frequently engage in, or are subjected to, risk-taking behaviours that may expose them to sexually transmitted infections and unwanted pregnancies. These include having multiple sexual partners and quite frequent partner turnover. High percentages also engage in unprotected sexual intercourse with various types of sexual partner (steady, casual and paid), and young women especially had often experienced sexual coercion. Qualitative data revealed a mixture of perceptions and practices affecting sexual intercourse among the young, such as having unplanned sex, engaging in sexual relations to display love or cement committed relationships, and having serial relationships, both monogamous and non-monogamous. We conclude that condom use should be a central focus of activities aimed at preventing adverse sexual health outcomes, but that new intervention approaches to encourage use of other contraceptives are also needed. Changes in sexual norms among young people also need to be acknowledged and accepted by older Thai generations in order for programs and interventions to combat negative sexual and reproductive health consequences to be more effective.     

Maximum likelihood estimation for mixtures of two gompertz distributions when censoring occurs

In estimating the proportion ‘cured’ after adjuvant treatment, a population of cancer patients can be assumed to be a mixture of two Gompertz subpopulations, those who will die of other causes with no evidence of disease relapse and those who will die of their primary cancer. Estimates of the parameters of the component dying of other causes can be obtained from census data, whereas maximum likelihood estimates for the proportion cured and for the parameters of the component of patients dying of cancer can be obtained from follow-up data.

This paper examines, through simulation of follow-up data, the feasibility of maximum likelihood estimation of a mixture of two Gompertz distributions when censoring occurs. Means, variances and mean square error of the maximum likelihood estimates and the estimated asymptotic variance-covariance matrix is obtained from the simulated samples. The relationship of these variances with sample size, proportion censored, mixing proportion and population parameters are considered.

Moderate sample size typical of cooperative trials yield clinically acceptable estimates. Both increasing sample size and decreasing proportion of censored data decreases variance and covariance of the unknown parameters. Useful results can be obtained with data which are as much as 50% censored. Moreover, if the sample size is sufficiently large, survival data which are as much as 70% censored can yield satisfactory results.     

Using local areas data to improve the lives of disadvantaged children and families

Because economic and social opportunities are unevenly distributed across England, the places in which children and young people are born and grow up can have significant influences on both their current well‐being and their future life chances. Data now available confirms the expected finding that the level of child well‐being found in an area tends to reflect its overall level of disadvantage. However, there are a number of exceptions to this general rule – local areas where child well‐being is either significantly better or worse than would be expected given the levels of advantage which exist there. Some of the possible explanations for these exceptions are considered, using additional data available from the mapping of children's services, particularly in relation to the provision of child and adolescent mental health services. It is argued that continued analysis of these different streams of data as they develop and mature over the coming years had an important role to play in assisting policy‐makers, service providers and local people, working collaboratively, to promote the well‐being of disadvantaged children and young people.
