Developing Empirically-Based Practice in Probation

This article examines the influence of research on social work practice, with special reference to probation, and argues that in order to maintain their well-earned reputation as providers of defensible alternatives to custody, probation officers need to attend more carefully to the findings of research and to review their practice accordingly. Further, it is argued that managers need to consider the content of practice as well as its structure, if they are to meet the challenges of the present decade. These discussions are placed in the context of an applied research project on one probation team's attempt to adopt a more structured and empirically-based approach to the setting up of a new groupwork programme.

Allocating Blame in Social Work

This article takes issue with those who assume that the responsibility for bad outcomes in social work, such as child deaths, is appropriately laid at the feet of individual workers. It examines the philosophical origins of such arguments, some recent applications within social work literature and their appropriateness to the realities of social work practice. The author argues that a morality of social work must recognize the social and organizational context in which it occurs.

Contemporary Studies of the Effectiveness of Social Work

This article is based upon an analysis of 95 experimental, quasi-experimental, preexperimental and client-opinion studies of the effectiveness of social work. Three-quarters of these screened studies show positive results within their different methodological conventions. An examination is made of which methods and patterns of helping are correlated with positive outcomes and the implications for practice, training, and management explored.

Community Care Services for the Mentally Ill

In this study a broadly representative sample of clients in the City of Westminster, receiving Care in the Community for reasons of mental ill-health, were interviewed regarding their experiences of, and levels of satisfaction with, services provided. The results reveal the vulnerability of services users, the benefits of community care, the high regard the majority have for their helpers, the limitations imposed by scarce resources, and the negative effects of only loose co-ordination between health and social services. Respondents also provide a rich source of data on how services might be improved.

Social work research: the state we’re in

This paper presents an argument in favour of a particular research strategy as the basis for evidence-based practice in social care. It presents some grounds for optimism and reviews the difficulties that need to be overcome if this model of evidence-based practice is to prevail over other, more laissez-faire, versions.

Implications for practice of recent effectiveness research

This article results from an analysis of 95 studies of the effectiveness of social work. The good news from this research, which features a wide range of demanding social problems, is that 75 per cent of results are positive. In this article the authors present their findings and consider their implications for practice.

Genomic instability in human lymphocytes irradiated with individual charged particles: Involvement of tumor necrosis factor a in irradiated cells but not bystander cells

Exposure to ionizing radiation can increase the risk of cancer, which is often characterized by genomic instability. In environmental exposures to high-LET radiation (e.g. Ra-222), it is unlikely that many cells will be traversed or that any cell will be traversed by more than one alpha particle, resulting in an in vivo bystander situation, potentially involving inflammation. Here primary human lymphocytes were irradiated with precise numbers of He-3(2+) ions delivered to defined cell population fractions, to as low as a single cell being traversed, resembling in vivo conditions. Also, we assessed the contribution to genomic instability of the pro-inflammatory cytokine tumor necrosis factor alpha (TNFA). Genomic instability was significantly elevated in irradiated groups ( greater than or equal totwofold over controls) and was comparable whether cells were traversed by one or two He-3(2+) ions. Interestingly, substantial heterogeneity in genomic instability between experiments was observed when only one cell was traversed. Genomic instability was significantly reduced (60%) in cultures in which all cells were irradiated in the presence of TNFA antibody, but not when fractions were irradiated under the same conditions, suggesting that TNFA may have a role in the initiation of genomic instability in irradiated cells but not bystander cells. These results have implications for low-dose exposure risks and cancer. (C) 2005 by Radiation Research Society.
