The use of unique statistical weights for estimating variances with the balanced half-sample technique

The balanced half-sample technique has been used for estimating variances in large scale sample surveys. This paper considers the bias and variability of two balanced half-sample variance estimators when unique statistical weights are assigned to the sample individuals. Two weighting schemes are considered. In the first, the statistical weights based on the entire sample are used for each of the individual half-samples while in the second, the weights are adjusted for each individual half-sample.Sampling experiments using computer generated data from populations with specified values for the strata parameters were performed. Their results indicate that the variance estimators based on the second method are subject to much less bias and variability than those based on the first.     

Inner Wellbeing: Concept and Validation of a New Approach to Subjective Perceptions of Wellbeing—India

This paper describes the conceptual development of a multi-domain, psychosocial model of ‘Inner Wellbeing’ (IWB) and assesses the construct validity of the scale designed to measure it. IWB expresses what people think and feel they are able to be and do. Drawing together scholarship in wellbeing and international development it is grounded in field research in marginalised, rural communities in the global South. Results from research in India at two points in time (2011 and 2013) are reported. At Time 1 (n = 287), we were unable to confirm an eight-factor, correlated model as distinct yet interrelated domains. However, at Time 2 (n = 335), we were able to confirm a revised, seven-factor correlated model with economic confidence, agency and participation, social connections, close relationships, physical and mental health, competence and self-worth, and values and meaning (five items per domain) as distinct yet interrelated domains. In particular, at Time 2, a seven-factor, correlated model provided a significantly better fit to the data than did a one-factor model.     

Color-Line as Fault-Line: Teaching Interethnic Relations in California in the 21st Century

In this article, I describe an undergraduate course on interethnic relations that I taught at a small, predominantly White, liberal arts college during the 1990s. First, I present the intellectual heart of the course (similarities and differences between Allport's [1954/1979] mainstream perspective and Du Bois' [1903/1969] oft-neglected, alternative perspective on race relations). Subsequently, I discuss the course background and a precipitating incident (verbal conflict between a White male student and a Black female student) that transformed the class. Finally, I reflect on my experiences, as well as individual and institutional factors (gender, institutional racism) that probably affected students' and faculty members' responses. Policy implications for courses on prejudice (and for teachers of such courses) are discussed .     

Domestic violence and child abuse: developing social work practice

This paper takes as its starting point the report produced by the Social Services Inspectorate (1995), entitled Domestic Violence and Social Care , which seeks to alert social workers to the links between domestic violence and child abuse and urges the profession to respond more effectively to these two interconnected forms of violence. Having examined the research findings which provide evidence for these links, the theoretical and service delivery contexts in which these two forms of violence have been studied and conceptualized by the social work profession, both in the United Kingdom and in the United States, are identified. Studies of the social work response to domestic violence are discussed and some of the difficulties experienced by social workers in responding effectively to the needs of families where both forms of violence are experienced are considered. In particular, the issues of 'invisible' men and 'trapped' women and children are explored. It is argued that effective social work intervention which challenges these stereotypes will require additional resources and the article concludes with a consideration of whether the Messages from Research report might herald a shift in the approach to child protection that would promote the allocation of resources to this area of work.     

Turning away from the public sector in children's out-of-home care: An English experiment

This paper reports on the evaluation of an English experiment which, for the first time, moved statutory social work support for children and young people in out-of-home care from the public to the private or independent sector. Five social work practices (SWPs), independent or semi-independent of local government, were established and evaluated using a matched control design with integrated process evaluation. Social work teams in the public sector, selected to correspond to key characteristics of the SWP sites, provided control sites.     

Weaving Sociology into New Zealand Social Work Education

Social work students and practitioners often struggle to apply sociological theories to practice situations. This is made difficult because the application of sociological theory for social work is still a contested area. To assist students and practitioners articulate and explain sociological theory in their social work practice, this paper introduces a practical teaching model—one that is theoretically rich and simple to use. The authors have used this model to teach sociology for first year New Zealand social work students, with pleasing results. Taught in the foundation year of degree study, we show that there is utility for this model throughout social work education, most notably in policy, research and practicum courses. Teaching sociology is not without its challenges, and these are discussed. We argue that this model offers students and practitioners a straightforward ‘nuts and bolts’ method that can easily be drawn on in class and in practice to guide sociological theorising. Further, societal and personal value tensions can be reflectively teased out. Importantly, the model allows for sets of sociological analyses to be rendered explicit for the practitioner, their colleagues and their clients.     

Online algorithms for maximizing weighted throughput of unit jobs with temperature constraints

We consider a temperature-aware online deadline scheduling model. The objective is to schedule a number of unit jobs, with release dates, deadlines, weights and heat contributions, to maximize the weighted throughput subject to a temperature threshold. We first give an optimally competitive randomized algorithm. Then we give a constant competitive randomized algorithm that allows a tradeoff between the maximum heat contribution of jobs and the competitiveness. Finally we consider the multiple processor case and give several tight upper and lower bounds.
