Evaluating the Quality of Social Work Supervision in UK Children’s Services: Comparing Self-Report and Independent Observations

Understanding how different forms of supervision support good social work practice and improve outcomes for people who use services is nearly impossible without reliable and valid evaluative measures. Yet the question of how best to evaluate the quality of supervision in different contexts is a complicated and as-yet-unsolved challenge. In this study, we observed 12 social work supervisors in a simulated supervision session offering support and guidance to an actor playing the part of an inexperienced social worker facing a casework-related crisis. A team of researchers analyzed these sessions using a customized skills-based coding framework. In addition, 19 social workers completed a questionnaire about their supervision experiences as provided by the same 12 supervisors. According to the coding framework, the supervisors demonstrated relatively modest skill levels, and we found low correlations among different skills. In contrast, according to the questionnaire data, supervisors had relatively high skill levels, and we found high correlations among different skills. The findings imply that although self-report remains the simplest way to evaluate supervision quality, other approaches are possible and may provide a different perspective. However, developing a reliable independent measure of supervision quality remains a noteworthy challenge.     

Engineering confederalism for Iraq

This article examines Iraqi political developments in the last few years. It argues that unless a constitutional mechanism for proper dispersal of political powers across Iraq's regions and branches of its government is developed quickly, it may become too late for defeating Islamic State in Iraq and Syria, stemming the sectarian and ethnic conflicts, overcoming its perpetual crises of governance or for keeping Iraq united. We suggest that a confederal structure is a better and lasting political solution for Iraq than federal or other structural configurations. We also argue that power-sharing and consensus must be intertwined directly into the constitutional fabric of the political structure.     

Collaboration and Internationalization of SMEs: Insights and Recommendations from a Systematic Review

This paper performs a systematic literature review of the undeniably diverse – and somewhat fragmented – current state of research on the collaborations and internationalization of small and medium‐sized enterprises (SMEs). We analyze key works and synthesize them into a framework that conceptually maps key antecedents, mediators, and moderators that influence the internationalization of SMEs. In addition, we highlight limitations of the literature, most notably in terms of theoretical fragmentation; extant theories are deployed and illustrated but rarely extended in a manner that significantly informs subsequent work. At an applied (but related) level, we argue the need for supplementary work that explores the distinct stages of internationalization – and the scope and scale of this process – rather than assuming closure around particular events. With this, we highlight the need for more rigorous and empirically informed explorations of contextual effects that take account of the consequences of developments in the global economic ecosystem.     

Variable selection for survival data with a class of adaptive elastic net techniques

The accelerated failure time (AFT) models have proved useful in many contexts, though heavy censoring (as for example in cancer survival) and high dimensionality (as for example in microarray data) cause difficulties for model fitting and model selection. We propose new approaches to variable selection for censored data, based on AFT models optimized using regularized weighted least squares. The regularized technique uses a mixture of \(\ell _1\) and \(\ell _2\) norm penalties under two proposed elastic net type approaches. One is the adaptive elastic net and the other is weighted elastic net. The approaches extend the original approaches proposed by Ghosh (Adaptive elastic net: an improvement of elastic net to achieve oracle properties, Technical Reports 2007) and Hong and Zhang (Math Model Nat Phenom 5(3):115–133 2010), respectively. We also extend the two proposed approaches by adding censoring observations as constraints into their model optimization frameworks. The approaches are evaluated on microarray and by simulation. We compare the performance of these approaches with six other variable selection techniques-three are generally used for censored data and the other three are correlation-based greedy methods used for high-dimensional data.     

Communication in Statistics-Theory and methods improved GQL estimation method for the generalised BINMA(1) model

In a recent research, the quasi-likelihood estimation methodology was developed to estimate the regression effects in the Generalized BINMA(1) (GBINMA(1)) process. The method provides consistent parameter estimates but, in the intermediate computations, moment estimating equations were used to estimate the serial- and cross-correlation parameters. This procedure may not result optimal parameter estimates, in particular, for the regression effects. This paper provides an alternative simpler GBINMA(1) process based on multivariate thinning properties where the main effects are estimated via a robust generalized quasi-likelihood (GQL) estimation approach. The two techniques are compared through some simulation experiments. A real-life data application is studied.     

Contested Ground: Network Governance in Australia's Migration Industry

This article challenges current understandings of the Australian migration industry's position in a network governance framework by shedding light on Registered Migration Agents’ (RMA) lived experiences of their profession. Using qualitative interview data collected from ten migration intermediaries across Australia, this article examines their experiences of their role in relation to the state and industry bodies. Placing migration intermediaries at the meso‐level of analysis, between macro‐level forces of the state and micro‐level agency of their clients, I argue primarily that the migration industry of Australia is a “contested ground” where intermediaries are embedded within complex negotiations with the state and legal frameworks, whilst also negotiating their legitimacy in a stigmatised profession. The findings of this study reveal migration intermediaries’ experiences of network governance as pivotal stakeholders, operating within a space characterized by complex configurations of autonomy and bureaucratic control.     

‘Ghost in the Shell’: Reflections on Fieldwork in Kazakhstan

After independence from the Soviet Union, Kazakhstan proclaimed Kazakhs the title ethnic group, and the Kazakh language the national language. This deprived the Russian-speaking population of its former dominant social position. Being a Russian-speaking citizen of Kazakhstan, the daughter of a half-Korean half-Russian father and a half-Kazakh half-German mother, I did my field work as a presumed ‘native’ anthropologist at Kazakhstan State University with linguistically divided groups of students. The relations between the field and the researcher disclosed different geopolitical realities of knowledge production and challenged the legacy of relativist methodology. I reflect on this experience and examine different conceptualisations of the native positionality in the post-Soviet context. Reflections in this paper raise new questions about nation-building in post-socialist states and about ‘nativeness’ itself, and contribute to the criticism of postmodern theory.     

International Remittances and Private Schooling: Evidence from Kerala,India

This study investigates the impact of international remittances on private school enrolment in Kerala. Using data from the 2010 Kerala Migration Survey and employing an instrumental variable (IV‐Probit) approach to address the endogeneity of migration, we found that remittances have a positive and significant effect on private school enrolment. After disaggregating the sample into different heterogeneous groups, we found that remittances have greater effect on boys, children residing in rural areas, and those belonging to socially advantageous groups and from higher wealth quintile. Children from lower wealth quintile and belonging to socially disadvantageous groups are least affected by migration and remittances.     

Essential Micro‐foundations for Contemporary Business Operations: Top Management Tangible Competencies,Relationship‐based Business Networks and Environmental Sustainability

Although various studies have emphasized linkages between firm competencies, networks and sustainability at organizational level, the links between top management tangible competencies (TMTCs) (e.g. contemporary relevant quantitative‐focused education such as big data analytics and data‐driven applications linked with the internet of things, relevant experience and analytical business applications), relationship‐based business networks (RBNs) and environmental sustainability have not been well established at micro‐level, and there is a literature gap in terms of investigating these relationships. This study examines these links based on the unique data collected from 175 top management representatives (chief executive officers and managing directors) working in food import and export firms headquartered in the UK and New Zealand. Our results from structural equation modelling indicate that TMTCs are the key determinants for building RBNs, mediating the correlation between TMTCs and environmental sustainability. Directly, the competencies also play a vital role towards environmental practices. The findings further depict that relationship‐oriented firms perform better compared to those which focus less on such networks. Consequently, our findings provide a deeper understanding of the micro‐foundations of environmental sustainability based on TMTCs rooted in the resource‐based view and RBNs entrenched in social network theory. We discuss the theoretical and practical implications of our findings, and we provide suggestions for future research.
