Towards a better understanding of correlation

Correlation is often used to assess both independence and linearity in two dimensions, but is not well understood in higher dimensions. Here we take a closer look at these uses of correlation in two dimensions and how these assessments might be extended to higher dimensions. Our discussion will focus on the simple case of understanding the nature of correlation for association models for two- and three-way contingency tables, but can also be considered in a more general setting.     

Towards an understanding of the female expatriate experience in Europe

The increased participation of women in the workforce has been one of the major changes in the structuring of the labour force in recent years, and it is anticipated that this trend will continue. Despite growing numbers of women in senior domestic management roles, the participation rates of women in international management remains low across the globe. In Europe, international management has generally been a masculine preserve. Much of our knowledge of female expatriation comes from North America and is based on the experiences of female managers working for North American MNCs. This article builds on that base of understanding but highlights a growing stream of research into female expatriation in Europe, which remains largely “invisible” to specialists outside Europe. Given the paucity of empirical research in this area in general and the need for a more international understanding of the phenomena which can arise from examining different contexts, the article suggests that researchers outside Europe may find useful insights in this paper which pulls together and summarises what we know from the existing research on female expatriates in Europe and offers some avenues for future research.     

Towards a strategic understanding of global teams and their HR implications: an expert dialogue

Abstract

Drawing on initial insights emerging from a panel at the EIBA 2016 Conference in Vienna, here discussants and expert panelists engage in a follow-on conversation on the HRM implications of global teams for international organizations. First we set out how HRM can enable global teams and their constituent members to overcome the new and considerable challenges of global teams. These challenges span levels of analysis, time and space. Next we debate global teams as a strategic response to the dual pressures of global integration and local adaptation. We consider what HRM is needed for global teams to successfully resolve this dilemma, challenging practitioners to move beyond the ‘best practices’ and ‘alignment’ dichotomy. Lastly we look to the future to consider implications for research. We propose a rich research agenda focused on the complexities of the global team context.     

Towards an holistic understanding of disruptions in Operations Management

The paper reviews the literature on maintenance management, integrates key dimensions of maintenance within a taxonomy of maintenance configurations, and explores the impact of differing configurations on contextual factors and operational performance. “Prevention”, “hard maintenance integration” and “soft maintenance integration” were identified as key maintenance variables. Data were collected from 253 Swedish manufacturing companies, and three distinct clusters were identified. “Proactive Maintainers” emphasized preventive maintenance policies. “IT Maintainers” relied on computerized and company-wide integrated information systems for maintenance. “Maintenance Laggers” emphasized all maintenance dimensions to lesser extent than the others. The importance of maintenance prevention and integration differ between contexts. There were subtle performance differences across identified configurations, but preventive and integrated maintenance were more important for companies seeking competitive process control and flexibility. There existed no group with any great emphasis on all three maintenance dimensions, but attaining truly high performance may require a rare mix of the three dimensions. This mix of variables could constitute a hypothesized “World Class Maintenance” group.     

Toward a better understanding of lead times in MRP systems

Lead times in MRP systems represent the planned amount of time allowed for orders to flow through the manufacturing system. Setting lead times is a major issue in the operation of MRP systems. There exists, however, very little documentation on just how lead times should be set.This study examines the effects lead times have on MRP-based manufacturing logistics systems. In particular, it examines the effects that lead times have on backlogs, order tardiness, and finished component inventories.A major finding is that changes to the level of planned lead times have both transient and steady state effects that may not necessarily operate in the same direction. A simple methodology is presented for setting the level of planned lead times when the criterion is finished component inventory.     

Towards an understanding of social networks among organizational self-initiated expatriates: a qualitative case study of a professional services firm

Drawing on a qualitative case study of 51 organizational self-initiated expatriates (OSIEs) in a professional services firm, this article investigates the role of networks during expatriation and, specifically, in the development of learning that is beneficial to both the individual expatriate and the global operations of the firm. First, we investigate the extent to which individual motivations to engage in OSIE impact on the development of networks. Second, we investigate individual's experiences of network development. Third, we investigate individual perceptions of the benefits of networks for both organizations and individual actors. The paper will report that professionals initiating their own expatriation develop continually expanding and composite networks such that mobility and networks evolve in a seemingly symbiotic relationship. In doing so, it contributes to our understanding of the role of agency in network development and extends our understanding of organizational self-initiated expatriation as a relatively under-researched phenomenon.     

When methods and theories collide: Toward a better understanding of improving unit performance in a multimarket firm

Logistics research in the area of performance measurement continues to receive attention from a variety of perspectives. One well-received perspective is that of efficiency. Data envelopment analysis is a well-studied analytical tool to identify best-practicing efficient operating units of the firm. But a theoretical linkage remains absent from the literature. Drawing upon theoretical perspectives of organization search and knowledge transfer, this study identifies conditions in which suitable role models (according to reference set analysis) may be unrealistic and thus warrant refinements. Ironically, it is through the existence of these particular analytical tools that we are able to develop and then test our framework and illustrate the practical implications. Moreover, this study is ideally suited to illustrating how the methodology is widely applicable among the growing number of multi-unit multi-market (MUMM) firms around the world, particularly given the diffusion of sophisticated performance information gathering technologies widely used in today’s information age.     

Nonlinearity in the effects of financial development and financial structure on unemployment

The positive role of the financial sector in promoting economic growth has been well established among academics and practitioners since the early 1990s. However, more recently, there has been increasing evidence pointing to a vanishing, and even negative, effect of financial sectors at high levels of financial depth, particularly since the global financial crisis of 2007?2009. Too much finance could hurt growth. The paper shifts the focus towards labor market outcomes by examining whether too much finance also hurts unemployment. Using a dynamic simultaneous model via system GMM estimation and a panel of 97 OECD and non-OECD countries for the period 1991–2015, we find that the answer depends on the type of finance and the extent of a country’s labor market flexibility. Specifically, (i) too much financial development hurts unemployment for countries with more rigid labor markets; (ii) too bank-centered or too little market-oriented financial systems worsen unemployment, particularly for countries with more flexible labor markets; and (iii) too much credit to private enterprises deteriorates unemployment in countries with more rigid labor markets, whereas too little credit to households worsens unemployment in countries with more flexible labor markets. Evidence also shows that these unemployment consequences possibly run through investment and entrepreneurship channels.     

Prices,debt and market structure in an agent-based model of the financial market

We develop an agent-based model in which heterogeneous and boundedly rational agents interact by trading a risky asset at an endogenously set price. Agents are endowed with balance sheets comprising the risky asset as well as cash on the asset side and equity capital as well as debt on the liabilities side. A number of findings emerge when simulating the model: we find that the empirically observable log-normal distribution of bank balance sheet size naturally emerges and that higher levels of leverage lead to a greater inequality among agents. Furthermore, greater leverage increases the frequency of bankruptcies and systemic events. Credit frictions, which we define as the stickiness of debt adjustments, are able to explain a key difference in the relation between leverage and assets observed for different bank types. Lowering credit frictions leads to an increasingly procyclical behavior of leverage, which is typical for investment banks. Nevertheless, the impact of credit frictions on the fragility of the model financial system is complex. Lower frictions do increase the stability of the system most of the time, while systemic events become more probable. In particular, we observe an increasing frequency of severe liquidity crises that can lead to the collapse of the entire model financial system.     

Payroll giving in the UK: donor incentives and influences on giving behaviour

Payroll giving became tax effective in 1987. Since then, it has grown steadily, but has never reached the success of payroll giving in the USA, where it accounts for the highest yielding and lowest cost form of fundraising. This paper looks at payroll giving in the UK and reports the findings of a large scale survey of payroll givers. It also examines tax reliefs in encouraging giving through the payroll, and the role of stakeholders in such charities, companies and agency charities.

Matching structure and strategy: Towards a market orientation in health care

The introduction of an ‘internal’ or ‘managed’ market mechanism into the National Health Service required fundamental structural reorganisation, involving the separation of purchaser and provider functions. While a degree of structural change has occurred among the emergent purchasing organisations subsequent to the initial reforms, there is a lack of corresponding evidence of ongoing structural change in acute provider units. Despite the existence of a direct relationship between organisational structure and strategy, the extent of change in the organisational structure of hospitals is questionable. Indeed at the macro level current acute hospital structures, that is NHS Trusts, are remarkably similar to ‘pre-reform’ structures, despite the unsuitability of these structures for the market orientation required by the internal market. Such prevalence arguably reflects the marginal effect that current managerial structures have had on those delivering services and the predominance of the medical hierarchies. Specifically, those responsible for the marketing of hospital services in current structures are not directly linked to those who deliver the service, in spite of the introduction of clinical directorate structures. Part of a broader study of the market behaviour of acute NHS Trusts in Scotland, this paper explores the organisational avenues open to health care providers to overcome this separation in the pursuit of market-led service delivery and concomitant market orientation.     

Prediction of donor lifetime value and the development of true segmented donor strategy

This paper is based on projects developed by WWAV Rapp Collins on behalf of two UK charities, Shelter and the NSPCC. The classic model used by nonprofit organisations for donor development programmes using the concept of lifetime value (LTV) is challenged and the paper describes the development of an alternative model. The paper assesses existing segmentation methodology and systems such as RFV, and analyses, step by step, how the new model was set up. There is particular emphasis on the scoring methods used and validation of the scores. Income from donors is likely to be maximised by efficiently separating the profitable from the unprofitable with the use of a more discriminating system.     

Uncertainty in the terms of trade and the optimal structure of a small open economy

Conclusions The main conclusion to emerge is that in moving from a certain to an uncertain world, the optimal size of the import-competing sector does not fall. For the case of CU it will rise. For PU, whether it increases or not depends on the decision rule used and the ranking of probabilities. Similarly for RU, the form of the utility function and the probability distribution help to determine the size of the import-competing sector. From other simulations we have carried out, we are confident that our main conclusion is fairly robust for this model.     

Towards a common understanding of the differences between purchasing, procurement and commissioning in the UK public sector

This paper recognises that commissioning has now become an important term in the lexicon of UK public policy but the term ‘commissioning’ is taking on a different meaning than that traditionally used within the purchasing and supply management community. The frequent inter-changeability of the terms ‘commissioning’, ‘procurement’ and ‘purchasing’ is now causing confusion and means different things to different people. Therefore the academic community needs to help practitioners understand the differences and implications. A document analysis of various UK Central Government departments’ commissioning frameworks was used to establish the key themes and compare commissioning, procurement and purchasing. This paper discusses the similarities and differences, and argues that commissioning is different from procurement, but that commissioning offers major opportunities for Procurement practitioners to make a strategic contribution.

Use of donor‐specified donation splitting: a technique to understand the impact of financial management on donor trust

• Two experiments investigated donors' willingness to split their donation into a proportion that the charity could use for administration costs and a portion that could be used to deliver the charity's services. Experiment 1 found that participants in the condition given the opportunity to split their donation into an amount for administration costs and an amount for service delivery gave a significantly smaller proportion of their overall donation to administration costs, when compared with participants in another condition who were simply asked what proportion of their donation they would be happy for the organization to use for administration costs. Experiment 2 manipulated the amount of information participants (donors) received about the breakdown of a charity's administration costs but found no significant change in the amount donated to administration. Both experiments show that donors were willing to donate approximately 15% of their donation directly to charity administration costs. Results are discussed in terms of understanding how a charity's financial management might be influencing donor's trust in the charity and providing charities with a degree of certainty in the proportion of donations they can spend on administration costs.
