Regression residuals and test statistics: Assessing naive outlier deletion

The authors derive the joint distributions of a studentized deleted residual and various regression quantities, calculated with all the data or with one case deleted. They show that the correlation between the studentized deleted residual and the deleted test statistic has an interesting interpretation in terms of well‐known regression quantities. These results allow them to examine the effect of applying some naive outlier deletion methods before making inferences about a regression parameter.     

Students’ Vocational Choices and Voluntary Action: A 12-Nation Study

Previous research on student involvement suggested that business and engineering students manifest lowest rates of voluntary action. Similarly, it was thought that social science students are the most involved in voluntary action, with students of natural sciences and humanities in the middle. However, there were very few studies that empirically compared these assertions. Furthermore, these assertions were not investigated from cross-cultural perspectives. Based on a study of students in 12 countries (N = 6,570), we found that even when controlling for background variables, social science students are actually less engaged in voluntary action than other students. Engineering students are higher than expected on voluntary action while students of humanities are the most involved in voluntary action. When studying these differences in the 12 selected countries, local cultures and norms form different sets of findings that suggest that there is no universal trend in choice of academic field and voluntary action.     

What Money Cannot Buy: The Distinctive and Multidimensional Impact of Volunteers

Although it is assumed that volunteers make an extremely important contribution to organizations and the community, studies that examine their direct impact are scarce. Using quantitative and qualitative data collected from clients, volunteers and staff at the Philadelphia Ronald McDonald House, examined is the impact of volunteers on the organization, the clients and on themselves. Volunteers had a high direct and indirect impact on recipients, including on their attitudes toward volunteering and their future behavior. Volunteers gained intrinsic and extrinsic benefits and, as expected, their participation had a positive impact on the organization. The study contributes to the body of knowledge on social impact and volunteering.     

Adoption Competent Clinical Practice: Defining Its Meaning and Development

The need for adoption competent mental health services has been well documented. However, the term “adoption-competent” has lacked a standardized, broadly accepted definition. This article reports findings from two related studies. The first examines how adoption competencies are demonstrated in practice by clinicians participating in an evidence-informed adoption competency training program. The second is an online survey designed to determine whether members of adoption kinship networks agree with a definition of an adoption competent mental health professional developed by experts. Both studies contribute to our understanding of what constitutes “adoption competent” clinical practice.     

Evaluating the outcomes of intensive critical thinking instruction for social work students

Social workers require critical thinking skills to analyse situations which present themselves in the course of professional work and in making decisions about the most appropriate forms of social work intervention. The 4-year Bachelor of Social Work degree at the University of Newcastle, Australia, introduced an intensive instructional unit on critical thinking at the beginning of the final year of the course. The Cornell Critical Thinking Test, the Ennis—Weir Essay Test and a qualitative student self-appraisal were administered to students in the fourth year of the degree prior to the intensive instructional unit on critical thinking and again after the unit had been completed. From the results it was concluded that explicit and concentrated instruction on critical thinking assisted social work students to improve their critical thinking abilities and to identify principles of critical thinking.     

Problem-Based Learning: An Integration of Theory and Field

Abstract

This article comments on the weaknesses of conventional field education models and presents a problem-based learning (PBL) model piloted at the University of Hong Kong. The PB Lprogram has three components: paper cases, skills workshops, and field project. Its aim is to help students integrate social work theories with practice and build their competence in self-directed learning. Findings on the preliminary assessment of the students' learning are reported. The experience was generally positive. The tutors' opinions of how the PBL program can fit in a social work curriculum and contribute to student learning are included, and the author describes the types of support required for model implementation.     

Endangered Children: Experiencing and Surviving the State as Failed Parent and Grandparent

The state removes children from ‘failed’ parentsto give them a better experience of parenting. This articleexamines the role that the state plays as parent to young mothersin care and grandparent to their children, drawing on a small-scalestudy undertaken in western Canada using grounded theory methodology.The findings were bleak: the state as parent and grandparentalso fails these children. We consider why this is the caseand make suggestions for ways forward by critiquing the ideologyof familialism that underpins the state’s punitive approachto these young mothers and their children. We also call forpolicies and a practice that enable practitioners to addressstructural inequalities such as poverty and racism alongsidethe capacity to respond to the personal needs of the young womenand their children as young people with dignity and rights.     

The Government of Disability: economics and power in welfare and work

The term government of disability refers to the ways that the lived experiences of people with accredited impairments are contextualised by economics and power in welfare and work. This paper explores how far a multiple perspective that develops a framework of the government of disability and the ontological ambiguity of impairment can take us towards contemporary understandings of disability, impairment and change in the UK.

The term the ontological ambiguity of impairment describes the ways that understandings of impairment have become more ambiguous, contributing to greater insecurities and fragmentation because of key changes in the government of disability. However, I argue that wider explanations of economic and power relationships are also necessary to develop a critical perspective of the contemporary government of disability, economics, and power in welfare and work.
