Social work with African refugee children and their families

This article explores the issues and dilemmas that arise when social workers attempt to work with African refugee and asylum seeking children and their families. There is a complex interplay between social workers’ skills and knowledge in this area and the prevailing social attitudes towards these groups of service users. By initially setting the context of mass movement of peoples from situations of danger in their countries of origin, the discussion highlights the key issues and shows the tensions of practice intervention in this area. Drawing on a small‐scale research study with social workers and discussions with immigration officers and workers in voluntary agencies working with refugees and asylum seekers, the article draws some conclusions about the lessons that can be learnt in order to improve practice.     

Forecasting Product Returns for Remanufacturing Operations

Driven by legislative pressures, an increasing number of manufacturing companies have been implementing comprehensive recycling and remanufacturing programs. The accurate forecasting of product returns is important for procurement decisions, production planning, and inventory and disposal management in such remanufacturing operations. In this study, we consider a manufacturer that also acts as a remanufacturer, and develop a generalized forecasting approach to determine the distribution of the returns of used products, as well as integrate it with an inventory model to enable production planning and control. We compare our forecasting approach to previous models and show that our approach is more consistent with continuous time, provides accurate estimates when the return lags are exponential in nature, and results in fewer units being held in inventory on average. The analysis revealed that these gains in accuracy resulted in the most cost savings when demand volumes for remanufactured products were high compared to the volume of returned products. Such situations require the frequent acquisition of cores to meet demand. The results show that significant cost savings can be achieved by using the proposed approach for sourcing product returns.     

Guidelines for Improving the Power Values of Statistical Tests for Nonresponse Bias Assessment in OM Research

The assessment of nonresponse bias in survey‐based empirical studies plays an important role in establishing the credibility of research results. Statistical methods that involve the comparison of responses from two groups (e.g., early vs. late respondents) on multiple characteristics, which are relevant to the study, are frequently utilized in the assessment of nonresponse bias. We consider the concepts of individual and complete statistical power used for multiple testing and show their relevance for determining the number of statistical tests to perform when assessing nonresponse bias. Our analysis of factors that influence both individual and complete power levels, yielded recommendations that can be used by operations management (OM) empirical researchers to improve their assessment of nonresponse bias. A power analysis of 61 survey‐based research papers published in three prestigious academic operations management journals, over the last decade, showed the occurrence of very low (<0.4) power levels in some of the statistical tests used for assessing nonresponse bias. Such low power levels can lead to erroneous conclusions about nonresponse bias, and are indicators of the need for more rigor in the assessment of nonresponse bias in OM research.     

Allies in Learning: Critical-Reflective Practice On-line with Allied Mental Health Practitioners

This paper is a reflection in action using personal examples of student feedback to guide teaching. In 2003, a post-graduate course was developed at Victoria University in New Zealand for occupational therapists and social workers employed in the mental health services. The aim of the programme is to provide opportunities for on-the-job learning while recruiting and retaining a skilled allied mental health workforce. The programme is publicly funded for students as part of a national workforce development strategy for mental health professionals. In this article, I reflect upon my first year as co-ordinator of the programme in 2007–2008. Due to my background as a social worker and my familiarity with social work theories of practice, I focus on my theories of teaching from a social work perspective while returning to reflect on themes for the student cohort as a whole. The programme is delivered using distance methods supported by nine days of on-site learning throughout the academic year. A problem-based learning (PBL) approach delivered on the Internet platform, ‘Blackboard’, enables students to study from their workplaces. The conceptual model of teaching evolved is a process of ‘creative attunement’ to the learner's world. I conclude by providing examples of the key elements of my teaching/learning model as a ‘work in progress’.
