Beyond attachment theory and therapy: Towards sensitive and evidence-based interventions with foster and adoptive families in distress

Elements of attachment theory have been embraced by practitioners endeavouring to assist foster and adopted children and their parents. Attachment theory articulates the potential risks of experiencing multiple caregivers; emphasizes the importance of close social relationships to development; and recognizes that substitute parents may not always have close relationships with children who have experienced adversities before joining them. Attachment theory offers concerned parents what they believe to be a scientific explanation about their lack of the close, satisfying parent–child relationship they desire. Yet the scientific base of attachment theory is limited both in terms of its ability to predict future behaviours, and especially with regard to its use as the underpinning theory for therapeutic intervention with children experiencing conduct problems. There is a critical need to review the role of attachment theory in child and family services and to consider its place among other explanations for children's disturbing behaviour. An important step towards pursuing alternative approaches is for researchers and practitioners to understand the reasons the attachment paradigm appeals to so many adoptive and foster parents, given the apparent widespread prevalence of attachment‐based interventions. Such understanding might assist in the development of adoption‐sensitive uses of appropriate evidence‐based treatment approaches.     

Maximum Likelihood Estimation for Cox's Regression Model Under Case–Cohort Sampling

Abstract.  Case–cohort sampling aims at reducing the data sampling and costs of large cohort studies. It is therefore important to estimate the parameters of interest as efficiently as possible. We present a maximum likelihood estimator (MLE) for a case–cohort study based on the proportional hazards assumption. The estimator shows finite sample properties that improve on those by the Self & Prentice [Ann. Statist. 16 (1988)] estimator. The size of the gain by the MLE varies with the level of the disease incidence and the variability of the relative risk over the considered population. The gain tends to be small when the disease incidence is low. The MLE is found by a simple EM algorithm that is easy to implement. Standard errors are estimated by a profile likelihood approach based on EM-aided differentiation.     

Statistics and the Bayesian mind

Did German flying bombs really target the poorer areas of London—or did the poor people underneath them just think that they did? How many millions of dollars will the current re-make of King Kong really gross? Oh, and how many taxis are there in London? The human mind can make very good guesses, it seems—and it uses Bayesian analysis to do so. Tom Griffiths and Joshua Tenenbaum explain.     

Universal Expressive Needs: A Critique and a Theory*

This article proposes a theory of expressive needs common to all human beings, which grow out of biologically based “coarse emotions”: grief, fear, anger, shame, joy, and love-attachment. In order to locate the new theory within the framework of existing thought on the relation between culture and biology, I classify, in a provisional way, the major theorists as belonging to one of the following schools of thought: instinctivist, culturist, or humanist. The weakness of each of these positions is outlined, and the way the new theory corrects the weaknesses is described.     

Modernisierung und Demokratisierung

Most social scientists agree that democracy is essentially a product of modernity: As soon as a society follows the path of modernization, especially by implementing economic reforms, a democratic transition seems inevitable. As the complexity of society increases, the demands on the governmental performance of the state rise. Accordingly, authoritarian developmental regimes will be replaced in the long term by liberal democracies. But the causes and mechanisms between modernization and democratization are still unclear. While most studies are based on functionalist concepts, this article explores the subject from a constitution theoretical perspective. The argument is developed in four steps: In the first step, I will discuss the contributions of Parsons and Luhmann to the explanation of democratization processes. In the second step, I will give an overview of recent non-functionalist concepts for the analysis of differentiation processes. In the third step, these concepts are used in order to investigate the relation between modernization and democratization on the case of South Korea (1979–1987). This empirical study focuses on structures of inequality in the social subsystems, the carriers and motives of pro-democratic protests, and finally the temporal patterns of interaction between the South Korean democratization movement and the authoritarian regime. In the fourth step, the explanatory potential of non-functional differentiation theories for the analysis of democratization processes will be discussed.     

SEX SEGREGATION IN VOLUNTEER WORK

Sex segregation in the workplace—the tendency for men and women to work in different occupations and jobs—remains widespread. Domestic chores are also sex-typed, but the extent to which sex segregation is found in other forms of nonwaged work, such as volunteering, is unknown. One theory about the work/nonwork interface predicts a positive relation between the two types of activity: sex segregation will be just as common in unpaid labor. Another theory predicts a negative relation: waged work and nonpaid work are dissimilar. Maximum likelihood probit models with selection are used to estimate the incidence of sex segregation among volunteers in a nationally representative sample of adult Americans (N = 91,807). Men are more likely to occupy leadership positions than women. They are more likely to do maintenance work and teach or coach, while women are more likely to prepare and serve food or clothing, raise money, and "help out" at events. Sex segregation is most pronounced among those who volunteer to help young people, but negligible among volunteers advocating a cause.
