Evidencing reflective practice in social work education: Theoretical uncertainties and practical challenges

Reflective practice has become an increasingly influential idea in social work education and, in the UK context, it has recently been acknowledged as key to ensuring that social workers are better equipped to engage in complex decision making and effective practice. However, there remains a lack of clarity about how this concept is defined and operationalised in teaching and learning and there has been little systematic empirical examination of its utility in facilitating professional development. Drawing on research with undergraduates at Queen's University Belfast, this paper aims to develop understanding of students' experience of reflective practice. The results suggest that agency systems that have become over-reliant on rules and procedures present formidable obstacles to learning both at an individual and at an organisational level. The paper argues that the relationship between how reflective practice is taught and how it is enacted in practice needs to be better understood if such obstacles are to be overcome. The paper concludes by considering the implications of the findings for developing reflective practice in social work education and practice and highlights the challenges that need to be addressed if reflection and critical thinking are to become more firmly embedded within agency systems and practice cultures.

Variable selection via RIVAL and its application in nuclear material detection

In many situations, the number of data points is fixed, and the asymptotic convergence results of popular model selection tools may not be useful. A new algorithm for model selection, RIVAL (removing irrelevant variables amidst Lasso iterations), is presented and shown to be particularly effective for a large but fixed number of data points. The algorithm is motivated by an application of nuclear material detection where all unknown parameters are to be non-negative. Thus, positive Lasso and its variants are analyzed. Then, RIVAL is proposed and is shown to have some desirable properties, namely the number of data points needed to have convergence is smaller than existing methods.

Ligand arsenic complexation and immunoperoxidase detection of metallothionein in the earthworm Lumbricus rubellus inhabiting arsenic-rich soil

Although earthworms have been found to inhabit arsenic-rich soils in the U.K., the mode of arsenic detoxification is currently unknown. Biochemical analyses and subcellular localization studies have indicated that As3+-thiol complexes may be involved; however, it is not known whether arsenic is capable of inducing the expression of metallothionein (MT) in earthworms. The specific aims of this paper were (a) to detect and gain an atomic characterization of ligand complexing by X-ray absorption spectrometry (XAS), and (b) to employ a polyclonal antibody raised against an earthworm MT isoform (w-MT2) to detect and localize the metalloprotein by immunoperoxidase histochemistry in the tissues of earthworms sampled from arsenic-rich soil. Data suggested that the proportion of arsenate to sulfur-bound species varies within specific earthworm tissues. Although some arsenic appeared to be in the form of arsenobetaine, the arsenic within the chlorogogenous tissue was predominantly coordinated with S in the form of -SH groups. This suggests the presence of an As::MT complex. Indeed, MT was detectable with a distinctly localized tissue and cellular distribution. While MT was not detectable in the surface epithelium or in the body wall musculature, immunoperoxidase histochemistry identified the presence of MT in chloragocytes around blood vessels, within the typhlosolar fold, and in the peri-intestinal region. Focal immunostaining was also detectable in a cohort of cells in the intestinal wall. The results of this study support the hypothesis that arsenic induces MT expression and is sequestered by the metalloprotein in certain target cells and tissues.

Welfare regime and social class variation in poverty and economic vulnerability in Europe: an analysis of EU-SILC

In this paper we address a set of interrelated issues. These comprise increasing concerns about reliance on nationally based income poverty measures in the context of EU enlargement, the relative merits of one-dimensional versus multidimensional approaches to poverty and social exclusion and the continuing relevance of class-based explanations of life chances. When identifying economically vulnerable groups we find that, contrary to the situation with national income poverty measures, levels of vulnerability vary systematically across welfare regimes. The multidimensional profile of the economically vulnerable sharply differentiates them from the remainder of the population. While they are also characterised by distinctively higher levels of multiple deprivation, a substantial majority of the economically vulnerable are not exposed to such deprivation. Unlike the national relative income approach, the focus on economic vulnerability reveals a pattern of class differentiation that is not dominated by the contrast between the self-employed and all others. In contrast to a European-wide relative income approach, it also simultaneously captures the fact that absolute levels of vulnerability are distinctively higher among the lower social classes in the less comprehensive and generous welfare regimes while class relativities are significantly sharper at the other end of the spectrum.

MODELING TRENDS IN SOCIAL FLUIDITY - THE CORE MODEL AND A MEASURED-VARIABLE APPROACH COMPARED

In this paper we employ Erikson and Goldthorpe's core model of social fluidity and a 'measured variable' approach to analyse trends in social mobility among men in the Republic of Ireland. Our analyses provide no evidence that the changes associated with industrialization have led to the increases in social fluidity predicted by the liberal theory of industrialism. The measured-variable approach we employ consistently provides a better fit to the Irish data than the core model. The application of the former model points to a degree of importance of the hierarchy dimension which is not captured adequately by the core model. It also suggests that the well-known distinctiveness of the Irish social mobility regime is open to explanation in terms of general dimensions rather than the peculiarities of the Irish case.

SOCIAL-CLASS, CLASS ORIGINS AND POLITICAL PARTISANSHIP IN THE REPUBLIC-OF-IRELAND

As Laver (1992) notes, people who write about Irish politics frequently describe Ireland as a rather peculiar place. One aspect of this peculiarity is that voters in the Republic of Ireland do not behave like their European counterparts. In particular, Irish voting patterns appear to be only weakly structured by social class. Recent contributions to the debate employing a more sophisticated categorisation of classes have led to some qualification of the 'politics without social bases' description, but still lead to the broad conclusion that any relationship which does exist between social divisions, on the one hand, and party preference, on the other, is, at most, quite marginal. In this paper we draw on data from the 1990 European Values Study to re-examine this issue. We apply a variety of models to the data, including logit regression and diagonal reference models (Sobel 1981, 1984) to explore the complex fashion in which class and political preferences are related in Ireland. We argue that the relationship between such preferences and social divisions are, in fact, greater than has been hitherto thought. In particular, we show the importance of taking into account not only social class but also class origins and class mobility in understanding the nature of political partisanship in the Republic of Ireland.

Social Identity and Youth Aggressive and Delinquent Behaviors in a Context of Political Violence

The goal of the current study was to examine the moderating role of in-group social identity on relations between youth exposure to sectarian antisocial behavior in the community and aggressive behaviors. Participants included 770 mother-child dyads living in interfaced neighborhoods of Belfast. Youth answered questions about aggressive and delinquent behaviors as well as the extent to which they targeted their behaviors toward members of the other group. Structural equation modeling results show that youth exposure to sectarian antisocial behavior is linked with increases in both general and sectarian aggression and delinquency over one year. Reflecting the positive and negative effects of social identity, in-group social identity moderated this link, strengthening the relationship between exposure to sectarian antisocial behavior in the community and aggression and delinquency towards the out-group. However, social identity weakened the effect for exposure to sectarian antisocial behavior in the community on general aggressive behaviors. Gender differences also emerged; the relation between exposure to sectarian antisocial behavior and sectarian aggression was stronger for boys. The results have implications for understanding the complex role of social identity in intergroup relations for youth in post-accord societies.
