The making of 'Home Improvements - tools for working with families in Aotearoa/ New Zealand'. Reflections on creating a video resource for teaching purposes

In this article, two social work practitioners explore, with all the wisdom of hindsight, the joys and pitfalls of venturing into video production as a medium for creating a teaching and learning resource. Their discoveries are organised under a number of key themes beginning with an idea and leading into commitment to a project involving a crew, a cast and a steep but captivating learning curve on the use of audio visual technology. Other practitioners similarly interested in the potential of this medium but without much experience, will find this article of great benefit in providing practical tips and insights, and demystifying the tasks and terminology associated with video production.     

Multichannel electroencephalographic analyses via dynamic regression models with time-varying lag–lead structure

Multiple time series of scalp electrical potential activity are generated routinely in electroencephalographic (EEG) studies. Such recordings provide important non-invasive data about brain function in human neuropsychiatric disorders. Analyses of EEG traces aim to isolate characteristics of their spatiotemporal dynamics that may be useful in diagnosis, or may improve the understanding of the underlying neurophysiology or may improve treatment through identifying predictors and indicators of clinical outcomes. We discuss the development and application of non-stationary time series models for multiple EEG series generated from individual subjects in a clinical neuropsychiatric setting. The subjects are depressed patients experiencing generalized tonic–clonic seizures elicited by electroconvulsive therapy (ECT) as antidepressant treatment. Two varieties of models—dynamic latent factor models and dynamic regression models—are introduced and studied. We discuss model motivation and form, and aspects of statistical analysis including parameter identifiability, posterior inference and implementation of these models via Markov chain Monte Carlo techniques. In an application to the analysis of a typical set of 19 EEG series recorded during an ECT seizure at different locations over a patient's scalp, these models reveal time-varying features across the series that are strongly related to the placement of the electrodes. We illustrate various model outputs, the exploration of such time-varying spatial structure and its relevance in the ECT study, and in basic EEG research in general.     

Bayesian Dynamic Factor Models and Portfolio Allocation

We discuss the development of dynamic factor models for multivariate financial time series, and the incorporation of stochastic volatility components for latent factor processes. Bayesian inference and computation is developed and explored in a study of the dynamic factor structure of daily spot exchange rates for a selection of international currencies. The models are direct generalizations of univariate stochastic volatility models and represent specific varieties of models recently discussed in the growing multivariate stochastic volatility literature. We discuss model fitting based on retrospective data and sequential analysis for forward filtering and short-term forecasting. Analyses are compared with results from the much simpler method of dynamic variance-matrix discounting that, for over a decade, has been a standard approach in applied financial econometrics. We study these models in analysis, forecasting, and sequential portfolio allocation for a selected set of international exchange-rate-return time series. Our goals are to understand a range of modeling questions arising in using these factor models and to explore empirical performance in portfolio construction relative to discount approaches. We report on our experiences and conclude with comments about the practical utility of structured factor models and on future potential model extensions.     

Knowledge Complementarity and Coordination in the Local Supply Chain: Some Empirical Evidence

Knowledge, managed or coordinated as a strategic resource, can help to internalize uncertainty or volatility and play an important role in generating and sustaining competitive advantage. One potentially important determinant of knowledge coordination between firms is the relative strength of the knowledge bases of the two partner companies. In the context of the local supply chain, this paper examines the extent of knowledge coordination between a group of 18 Northern Ireland‐based MNE plants and their local suppliers. A typology of knowledge complementarity is developed and related to the extent of firms' knowledge coordination activities. The analysis suggests three main empirical results. First, and somewhat unexpectedly, the relationship between MNE plants and their suppliers is characterized by a wide range of configurations of knowledge complementarity. Second, clear differentials exist between the occurrence of knowledge coordination activities incidental to normal trading relations and more intentional knowledge coordination activities. Third, no direct link was evident between knowledge complementarity and the level of knowledge coordination. The implication is that firms' willingness to coordinate knowledge, something that may be strategically determined, is more important than capability in determining the extent of knowledge coordination.     

The Equality Effects of the ‘Hyper‐formalization’ of Selection

This paper explores how formalization of employee selection procedures for the purpose of ensuring equality of opportunity can become so extensive that the intended outcome of fairness is undermined. Drawing on empirical evidence from a large media organization, the analysis reveals the detrimental impact of formalization in relation to the recruitment of ethnic minority staff. While the existing literature describes how, during recruitment of employees, the circumvention of formal equality procedures can occur through managerial neglect and manipulation, the analysis in this paper shows that, paradoxically, circumvention can also occur through compliance with procedures. This new category takes three forms (robotic, defensive and malicious) and appears under conditions of excessive formalization – the term hyper‐formalization is coined to describe this. The paper develops new concepts that add to understanding of the limitations of equality and diversity procedures, and brings fresh challenges to some of the liberal assumptions about the efficacy and desirability of formalization for achieving fairness.     

The Institutionalization of Third Stream Activities in UK Higher Education: The Role of Discourse and Metrics

In this paper we examine the institutionalization of a new organizational practice around third stream activities in UK higher education from 1994 to 2008. Employing a longitudinal research design, involving archival, survey and contemporary interview data, we show how a new organizational practice diffused through the use of discourse and metrics around commercialization but over time was threatened on pure economic criteria. In response to the threat we explore how actors worked to institutionalize the new practice, reshaping both discourse and metrics to ensure that they were robust so that they could align with the interests and values of major stakeholders. In addition, actors worked to align discourse and metrics, as any misalignment between the two would have undermined the institutionalization of the new organizational practice.     

Similarities and Differences between Leadership and Management: High‐Performance Competencies in the British Royal Navy

This paper describes the research, analysis and development of a model clarifying the similarities and differences in competencies and personality factors 1 associated with effective Leadership and Management in the Royal Navy. A questionnaire study was conducted on a sample of 261 Officers and Ratings (Sailors). Their performance was rated through the organization's rigorous appraisal process, whilst competency and personality data were gathered through the Occupational Personality Questionnaire and the Leadership Dimensions Questionnaire. The results identify the common and unique relevance of specific competencies and personality factors and so provide an illuminating insight into the differences between the constructs of leadership and management. The critical factors related to effective leadership and management performance are also identified.     

The model of human occupation: understanding the worker who is injured or disabled

This paper discusses application of the model of human occupation to the worker with an injury or disability. Concepts from the model of human occupation (MOHO) are used to frame potential work-related strengths and weaknesses. Using MOHO as a framework to understand the worker with an injury or disability provides a more complete and holistic understanding of the many factors which can affect a worker. In particular, the model illuminates how factors of capacity, motivation, lifestyle, and environment inter-relate in determining a worker's success or failure. Implications for using the model to achieve a more effective work-related practice are discussed.     

Women's Employment in Transition, 1992–4: the Case of Poland

Since the early 1990s the Polish economy has, in the move towards a market economy, undergone substantial economic reforms which resulted initially in a severe recession and notably in widespread unemployment. In a country where women have traditionally played a major role in the workforce it is pertinent to ask how their role has been affected during the early years of transition to a market economy, what factors explain this, and what their employment prospects are likely to be in a free market economy. After sketching the key features of women's employment in Poland pre-transition the article then addresses these questions using data drawn mainly from the Labour Force Surveys of 1992 and 1994. It finds that women's labour market position has been changing and in 1994 could be said to be mixed: while on the one hand it seems to be deteriorating (rising rates of inactivity and unemployment, the feminization of part-time work), on the other women seem to have been relatively protected from the worst effects of marketization and are in a better position than men according to some unemployment indicators. Prospects for women's employment under a free market economy also appear to be mixed, with much depending on whether the Polish government introduces a framework of national measures to support and encourage women who enter into paid employment.     

Forecasting in conditions of uncertainty

Has the business environment grown in uncertainty? In this paper the authors suggest that the root problem is not uncertainty but the malevolence of events these past few years. In turn, this has made uncertainty and the techniques developed to cope with its consequences all the more important to the firm. But while improved forecasting may take the difference between a potentially profitable project and corporate disaster, good forecasting by itself is not enough. Most firms would benefit from examining their forecasting performance in relation to strategic decisionmaking and the various options available. The authors conclude that only in an organization where integration between expert forecaster and forecast user has been achieved can the full benefits of improved forecasting be realized.
