Social Work and Social Justice in Northern Ireland: Towards a New Occupational Space

Correspondence to: Dr John Pinkerton, School of Social Work, Queens University Belfast, 7 Lennoxvale, Belfast BT9 5BY, Northern Ireland. E-mail j.pinkerton{at}qub.ac.uk Summary This article considers the concept of social justice by referenceto the experience of social work in Northern Ireland duringthe past forty years of communal, paramilitary and state violence.It notes the contested nature of the concept and its chequeredhistory within the professional ideology of social work generallyand its absence as a significant explanatory and motivationalconcept for social workers in Northern Ireland to date. It arguesthat in the emerging post-conflict situation social work asa profession needs to operationalize a view of social justicethat acknowledges social and cultural diversity in order toredefine the profession itself and direct its relationship toboth the state and civil society.     

Determinants of outcome in the pathways through care for children hearing voices

Auditory hallucination, or hearing voices, is generally associated with psychopathology. In psychiatry it is inter-preted as a symptom of an illness, with no connection to the individual's life history. Voice hallucinations in childhood occur in a variety of contexts and have variable long-term outcomes. Little is known about the course of the experience. In this study, 80 children and youngsters hearing voices were interviewed on four occasions over a period of three years about the content of the voices and their overall experience of voices, focusing on the determinants for a promising outcome in the pathways through care. The results indicate that the need for care in the context of the experience of voices is associated not only with high levels of problem behaviour and associated negative symptoms of psychosis, but also, independently, with an appraisal of the voices in terms of anxiety, depression, dissociation and frequency of occurrence. In 60 per cent of the participants the voices disappeared during the three-year research period. The relationship between the disappearance of voices and the course of mental health treatment is, however, ambiguous.     

The role of leadership self-efficacy and stereotype activation on cardiovascular,behavioral and self-report responses in the leadership domain

This research examines female leaders' responses to the gender–leader stereotype and the role of leadership self-efficacy in these responses. Using the biopsychosocial model of threat and challenge, this laboratory experiment examined women's cardiovascular, behavioral (i.e., performance), and self-report responses to the negative female leader stereotype as a function of leadership efficacy. Female participants, selected on leadership efficacy scores, served as leaders of ostensible three-person groups within an immersive virtual environment. Half were explicitly primed with the negative stereotype. As predicted, women with high, as opposed to low, percepts of leadership self-efficacy exhibited cardiovascular patterns of threat when performing the leadership task, and they performed better in the explicit stereotype activation condition compared to those not explicitly primed. Additionally, this threat was consistent with positive reactance responses on behavioral and self-report measures. Low efficacy leaders were not threatened, but they did show stereotype priming effects by assimilating to the negative stereotype on the self-report and behavioral measures. This research provides greater insight into stereotype reactance effects and highlights the role of self-efficacy in moderating stereotype threat and stereotype priming effects.     

The future of HRD research: Strengths,weaknesses, opportunities,threats and actions

This article clarifies the boundaries of human resource development (HRD) with respect to other concepts frequently used and misused in HRD literature. Through a proposition, a set of criteria for human resources is presented. A cross-culture literature comparison of the criteria demonstrates the consistency of the connotation in two contrasting cultures. This study has important implications for HRD research, practice and continued theory development effort. It relates to the identity and distinctiveness of HRD discipline, as well as the domain of HRD research and practice.     

Issues in end-of-life product recovery and reverse logistics

There is a fundamental shift in waste management responsibility from the private waste management industry and local governments towards manufacturers, distributors, and retailers. In recent years the responsibility of manufacturers has been extended to cover the entire life of certain products. This also includes responsibility for the products safe disposal. As the enforcement of environmental legislation becomes more stringent and an increasing number of customers are demanding take-back of their old products, companies are beginning to focus on possible distribution channels for the return of their products i.e. reverse logistics. The aim of this paper is to examine the emerging issues in reverse logistics, in particular the information requirements for reverse logistics within the Extended Enterprise. A study of end-of-life vehicles (ELVs) will illustrate the specific information flow between the key players within the automotive industry. This paper addresses the initial development of possible distribution channels, their key operational decisions and supporting information systems for the recycling of end of life products.     

Failure and maintenance data extraction from power plant maintenance management databases

Reliability analysis is plagued by a lack of accurate data, leading to suboptimal parameter estimates and inaccurate decisions about replacement intervals and preventive maintenance activities. This paper discusses some of the problems associated with failure and maintenance data extraction from coal-fired power plant maintenance databases. Data from four generating units were observed for over 5 years and a reasonable number of equipment classes reviewed. The coal mills are identified as significant equipment that affects the availability of the generating units. This paper describes the interplay of events which includes failure modes, failure, repair and operating time. We investigate a database showing operation of coal mills, and give an exploratory data analysis in which we investigate engineering hypotheses related to mill operation. A competing risk probability model is proposed which captures some of the observed features of the systems under study.
