Some principles for surveillance adopted for multivariate processes with a common change point

The surveillance of multivariate processes has received growing attention during the last decade. Several generalizations of well-known methods such as Shewhart, CUSUM and EWMA charts have been proposed. Many of these multivariate procedures are based on a univariate summarized statistic of the multivariate observations, usually the likelihood ratio statistic. In this paper we consider the surveillance of multivariate observation processes for a shift between two fully specified alternatives. The effect of the dimension reduction using likelihood ratio statistics are discussed in the context of sufficiency properties. Also, an example of the loss of efficiency when not using the univariate sufficient statistic is given. Furthermore, a likelihood ratio method, the LR method, for constructing surveillance procedures is suggested for multivariate surveillance situations. It is shown to produce univariate surveillance procedures based on the sufficient likelihood ratios. As the LR procedure has several optimality properties in the univariate, it is also used here as a benchmark for comparisons between multivariate surveillance procedures     

Running hard to stand still: Communication and information technology within social work training

Recent years have seen rapid technological changes and these have impacted on social work and social work education. Social work educators struggle to keep pace with these changes. Drawing on the author's own experience, this article outlines some key resources that are available to social work educators and students, reflects on the role of 'Communication and Information Technology' within the social work curriculum, and looks towards future developments in relation to online learning.     

Assessment of social work students: Standpoint and strong objectivity

The aim of this paper is to consider epistemological issues relating to the assessment of social work students. It will review the development of social work education and in particular the changes that have occurred in assessing the practice of social work students in England and Wales. It explores models of practice assessment. Factors relating to maintaining professional standards, whilst taking into consideration issues of justice, are addressed. It explores the potential benefits of using a second opinion in the assessment of marginal or failing students on practice placement. Assessment is linked to how students may perform as qualified practitioners; this raises issues related both to the nature of objectivity, and standpoint in assessment.     

Wages Differences Between Temporary and Permanent Immigrants1

Temporary “guestworker” programs are often assumed to have less impact on native-born workers than permanent immigration. However, there are theoretical reasons to expect temporary immigrants to accept lower wages and thus for temporary migration to have a greater adverse impact on receiving country wages. This article develops these theoretical insights and tests for differences in wages paid to temporary and permanent undocumented Mexican immigrants. Survey data from Mexico shows that temporary immigrants earned wages about 12% lower than permanent immigrants. Controlling for human and social capital, a 7.4% difference in wages remains. Among married immigrants, temporary immigrants earn 9.6% lower wages with these same controls.     

The forms of power and the forms of cities: building on Charles Tilly

Chuck Tilly’s late work on coercion, capital, and trust is provocative when applied to changes in urban form. Extending those categories for use in tracing the history of conflicts in cities about how development should be handled highlights the changing roles of economic and physical and cultural power, and the growing importance of trust in these processes. This is a speculative article with a political hope. The speculation is around the potential of using an expanded version of key categories of Charles Tilly’s to create a framework for understanding the nature of change in the form of cities over time. The political hope is to use that framework to illuminate the possibilities of social change in cities today in the direction of social justice.     

Developmental Issues in Career Maturity and Career Decision Status

There is considerable diversity in the literature regarding age and gender differences on career maturity and career decision status. There is also a dearth of data on high school samples. The present study reports cross‐sectional data from 1,971 Australian adolescents, ages 12.51‐17.99 years, who completed the Career Decision Scale (S. H. Osipow, C. G. Carney, J. Winer, B. Yanico, & M. Koschier, 1976) and the Career Development Inventory (Australian; J. Lokan, 1984). Results illustrated a developmental progression in career maturity, although a less uniform pattern emerged with gender differences. Findings regarding career indecision also presented a complex picture and highlight the need to focus on other demographic and contextual factors.     

Promoting Children's Welfare by Inter‐professional Practice and Learning in Social Work and Primary Care

Social work in the United Kingdom is an activity that benefits from, and often requires, co‐operation between different staff and across different professions. How this is to be achieved has been a central dilemma for practice and policy for many years. Primary care health services often play a key role. New policy and practice developments are designed to promote inter‐professional working with children, where research has shown significant problems in the community‐based health care of looked after children, children leaving care, and children at serious risk. There is, however, little evidence from research that supports current developments in inter‐professional practice; analysis of the particular nature of the inter‐professional problems is lacking, as are therefore the relevant inter‐professional solutions. A framework for better analysis, linked to developments in practice‐based research, one that would yield significant improvements for children's welfare, is presented here.     

Changing Spousal Roles and Their Effect on Recovery in Gamblers Anonymous: GamAnon,Social Support,Wives and Husbands

This paper examines changing spousal roles and their effects upon recovery in Gamblers Anonymous (GA). It is based upon a qualitative study designed to gage uniformity as well as variations in approaches to recovery in GA. Interviews were conducted with 39 GA members (26 men, 13 women; mean age 56.5 years). Though the study was based in the Toronto area, only 13 interviews involved participants from that region. Phone interviews were conducted with GA members from various regions of both Canada and the US. GamAnon, GA’s sister fellowship, has been designed for anyone affected seriously by someone’s gambling problem. In practice, GamAnon comprises mostly women––spouses of male GA members––who traditionally have taken a keen interest in the ways in which their husbands achieve and maintain abstinence from gambling. Changing spousal roles have led to fewer women joining GamAnon, as many opt instead to part with troubled spouses. As well, more women are attending GA than in the past, typically with husbands who are disinclined to join GamAnon. All of this has drastically altered how GA members pursue recovery. These changes and their implications are discussed.
