Too scared to go sick? The management and the manifestations of workplace attendance in the food retail sector

This article is a response to Taylor et al’s (2010) call for further research regarding workplace attendance. It examines the new politics of absence management in the UK and Cyprus in food retail sector, identifying a dual approach in managing attendance across the two countries. The first approach suggested the penalization of absence, whilst the second focused on the prevention of absence through accommodation. The article argues that ‘coercion’ is not the sole vehicle to tackle high absence in food retailing rather it suggests the development of other practices to enhance cooperation to regular attendance. The research identifies significant differences regarding the formality of these processes between the two countries, and suggests the generation of a particular attendance culture within the organisations, one that is not merely a culture of fear, as Taylor et al (2010) suggest, but rather a culture that includes accommodation and cooperation.     

Pitfalls of testing non-nested hypotheses by the lagrange multiplier method

In applied research in econometrics a general model determined from the current knowledge of economic theory often establishes a ‘natural’ method of embedding a number of otherwise non-nested hypotheses. Under these circumstances, significant tests of various hypotheses can be carried out within the classical framework, and tests of non-nested or separate families of hypotheses do not require development of new statistical methods. The application of some suitable variant of likelihood ratio testing procedure will be quite appropriate.There are, however, many ocassions in applied econometrics where the hypotheses under consideration are intended to provide genuine rival explanations of the same given phenomenon and the state of economic theory is not such as to furnish us with a general model that contains both of the rival hypotheses in a ‘natural’ and theoretically consistent manner. A number of investigators have advocated that even when a ‘natural’ comprehensive model containing both of the hypotheses under consideration cannot be obtained from theoretical considerations, it is still appropriate to base significant tests of non-nested hypotheses upon a combined model ‘artificially’ constructed from the rival alternatives. Moreover, in a recent paper on the application of Lagrange Multiplier (LM) tests to model specification, T.S. Breusch and A.R. Pagan (1980) have claimed that Cox's test statistic is connected to an LM or ‘score’ statistic derived from the application of the LM method to an exponentially combined model earlier employed by A.C. Atkinson (1970).Although the use of ‘artificially’ constructed comprehensive models fortesting separate families of hypotheses is analytically tempting, nevertheless it is subject to two major difficulties. Firstly, in many cases of interest in econometrics, the structural parameters under the combined hypothesis are not identified. Secondly, the log likelihood function of the artificially constructed model has singularities under both the null and alternative hypotheses.The paper firstly examines the derivation of LM statistics in the case of non-nested hypotheses and shows that Atkinson's general test statistic, or Breusch and Pagan's result, can be regarded as an LM test if the parameters of the alternative hypothesis are known. The paper also shows that unless all the parameters of the combined models are identified, no meaningful test of the separate families of the hypotheses by the artificial embedding procedure is possible, and in the identified case an expression for the LM statistic which avoids the problem of the singularity of the information matrix under the null and the alternative hypotheses is obtained.The paper concludes that none of the artificially embedding procedures are satisfactory for testing non-nested models and should be abandoned. It, however, emphasizes that despite these difficulties associated with the use of artificial embedding procedures, Cox's original statistic (which is not derived as an LM statistic and does not depend on any arbitrary synthetic combination of hypotheses) can still be employed as a useful procedure for testing the rival hypotheses often encountered in applied econometrics.     

Anticipating special events in Emergency Department forecasting

Accurate daily forecast of Emergency Department (ED) attendance helps roster planners in allocating available resources more effectively and potentially influences staffing. Since special events affect human behaviours, they may increase or decrease the demand for ED services. Therefore, it is crucial to model their impact and use them to forecast future attendance to improve roster planning and avoid reactive strategies. In this paper, we propose, for the first time, a forecasting model to generate both point and probabilistic daily forecast of ED attendance. We model the impact of special events on ED attendance by considering real-life ED data. We benchmark the accuracy of our model against three time-series techniques and a regression model that does not consider special events. We show that the proposed model outperforms its benchmarks across all horizons for both point and probabilistic forecasts. Results also show that our model is more robust with an increasing forecasting horizon. Moreover, we provide evidence on how different types of special events may increase or decrease ED attendance. Our model can easily be adapted for use not only by EDs but also by other health services. It could also be generalised to include more types of special events.     

Effectiveness of Q-learning as a tool for calibrating agent-based supply network models

This paper examines effectiveness of Q-learning as a tool for specifying agent attributes and behaviours in agent-based supply network models. Agent-based modelling (ABM) has been increasingly employed to study supply chain and supply network problems. A challenging task in building agent-based supply network models is to properly specify agent attributes and behaviours. Machine learning techniques, such as Q-learning, can be a useful tool for this purpose. Q-learning is a reinforcement learning technique that has been shown to be an effective adaptation and searching mechanism in distributed settings. In this study, Q-learning is employed by supply network agents to search for ‘optimal’ values for a parameter in their operating policies simultaneously and independently. Methods are designed to identify the ‘optimal’ parameter values against which effectiveness of the learning is evaluated. Robustness of the learning's effectiveness is also examined through consideration of different model settings and scenarios. Results show that Q-learning is very effective in finding the ‘optimal’ parameter values in all model settings and scenarios considered.     

WICKEDNESS IN SOCIAL CHOICE

In an article from 1973, Rittel and Webber distinguished between ‘tame’ or ‘benign’ problems on the one hand and ‘wicked’ problems on the other. The authors argued that wicked problems occur in nearly all public policy issues. Since different groups adhere to different value-sets, solutions can only be expressed as better or worse. By no means can they be viewed as definitive or objective. In this paper we consider, from this very angle, the theory of social choice which is about the aggregation of individual preferences with the aim to derive a consistent social preference. We show that collective choice offers wicked problems of various types which differ in their degree of severity. We hereby concentrate on welfare functions and voting schemes of different kinds and discuss these in the light of various criteria such as Arrow's independence condition, Condorcet consistency, monotonicity, manipulability, and other properties.     

Is there a bigger and better future for employer branding? Facing up to innovation,corporate reputations and wicked problems in SHRM

Employer branding is becoming an increasingly important topic for research and practice in multinational enterprises (MNEs) because it plays directly into their corporate reputation, talent management and employee engagement agendas. In this paper, we argue that the potential effects of employer branding have yet to be fully understood because current theory and practice have failed to connect this internal application of marketing and branding to the key reputational and innovation agendas of MNEs, both of which are at the heart of another strategic agenda – effective corporate governance. However, these agendas are characterised by ‘wicked problems’ in MNEs, which have their origins in competing logics in strategic human resource management (SHRM). These problems need to be articulated and understood before they can be addressed. This paper proceeds by (1) setting out a definition and model of employer branding and how it potentially articulates with corporate governance, innovation and organisational reputations, (2) discussing and analysing the ‘wicked problems’ resulting from the sometimes contradictory logics underpinning innovation and corporate reputations and SHRM in MNEs and (3) evaluating the potential of employer branding as a contribution to the third SHRM approach – HR strategy-in-action – as a way of resolving three particularly wicked problems in MNEs. We conclude with some ideas for research and practice on the future for employer branding.     

An application of search theory to the analysis of regional labour markets

This paper argues that the theoretical framework conventionally used by regional economists when analysing labour markets does not allow the spatial dimension of these markets to be discussed in a wholly satisfactory way. Search theory, which has been little used in regional economics, offers a means of overcoming this limitation. A search theory of labour markets is developed which includes as an exogenous variable the cost of travelling between home and work. The theory is shown to imply an inverse relationship between ‘accessibility to jobs’ and ‘duration of unemployment’.     

Unfolding event histories: Scaling of non-repeating events

The present paper discusses the use of Coombs' (1950, 1964) unfolding procedure applied to event history data. This procedure is appropriate when several stimuli are rated according to the individuals' preference, and yields scale values for stimuli and individuals, as well as a ‘best’ order of stimuli. We propose to consider the order of occurrence in time of non-repeatable events (such as first marriage, leaving home, and first job) as an indication of the subjects' preference for these stimuli. In that case unfolding may be applied to the analysis of event history-data. The statistical principles of unfolding analysis in general are briefly discussed. Subsequently an illustration is given, using data concerning the life course of 216 Dutch women of birth cohort 1961, concerning five events: first steady relationship, leaving home, first child, first job, and first occurrence of living together. It is shown that these events can be ordered at an underlying one-dimensional continuum on which individuals can be scaled. Furthermore, using regression analysis it is shown that the location of the subjects at this continuum correlates significantly with various explanatory variables, showing how unfolding may be used in practical applications.     

Creating whole life value proxemics in construction projects

Whole life value is introduced as a concept for evaluating construction projects, which extends beyond the more typical use of optimized (equilibrium) utility preferences. By linking value and sustainability the concept allows for the consideration of ‘price‐less’ evaluations within the construction project process. As an industry exposed perhaps more than any other to issues of public space and environmental impact, construction is being driven towards the use of complex, multi‐issue consultations with stakeholders within which whole life value can operate as a contextual limit. By investigating traditional cost–benefit analysis routes, and then what are called ‘aspects of sustainability’, an argument is advanced for these consultations to be ongoing rather than one‐off events. As such, they are to concern themselves with the framework of relationships (proxemics) by which distinct evaluations might be articulated and understood through the project process, rather than just how one arrives at a consensus of opinion. It is argued that the concept of value can only be applied fully to any project if consideration has been given to the ambience and context of stakeholder relations and attitudes as opposed to just the prevailing opinions. The virtue of such stakeholder involvement lies not in its ‘rubber stamping’ a separate process of activity, but in ensuring value is realized across asset life through a focus on attaining and sustaining conditions for the reflective articulation of need.

Ethnic preference for the arts: the role of the social experience as attendance motivation

This paper addresses the issue of the level of ethnic group attendance at the arts, with a special emphasis on African American attendance at classical music concerts. Current attendance data will be examined to determine if there is a difference in attendance rates when the traditional determiners for attendance — education and income — are similar. The paper proposes that the lower rates of attendance for ethnic groups may not be the result of differences in levels of education or income, but are the result of these groups having their own values and tastes that affect the benefits that they desire from attendance. To explore this proposed theory, the results of a survey of an arts event successful in attracting an ethnic audience will be analysed to see if it can provide insight as to whether ethnic audiences have unique attendance motivation. This is important to marketing as these benefits must be included in the artistic event and promoted to the potential ethnic audience. Copyright © 2002 Henry Stewart Publications     

Business is Show Business: Management Presentations as Performance

While there is continual scholarly interest in the ‘organization as theatre’ metaphor, extant dramaturgical perspectives limit the ability to account for aesthetic experiences in theatrical situations. This study provides a different methodological lens for looking at ‘theatre’ in organizations and illustrates that an inclusion of performance theory can be particularly valuable for understanding aesthetic techniques which are increasingly employed in organizations. Responding to calls for aesthetic studies, this article analyses large‐scale management presentations such as annual general meetings, press conferences, and analyst meetings ‘as performance’ instead of re‐labelling them as if they were drama. Drawing on the latest theatre theory and introducing a tool for performance analysis, the study accounts for the aesthetic experience and describes the complex interplay of scenography, lighting, clothing, managers' performance style, rhetoric, and audience interaction, showing that these organizational events are co‐created and contested theatrical performances with a potential for resistance and possible change as well as for persuasion.     

Absence management of migrant agency workers in the food manufacturing sector

Temporary workers in low-skilled roles often experience ‘hard’ HRM practices, for example the use of the Bradford Factor to monitor absence, rather than using incentives to reward attendance. However, this peripheral workforce has become increasingly diverse in the UK since the A8 European Union expansion, which has seen over a million migrants from central and eastern Europe register to work in the UK. Importantly, there is also heterogeneity within this group of workers, for example between those who intend to migrate for a short period of time then return, and those who are more settled and wish to develop a career. By considering the particular case of absence management, this paper examines how these different groups of migrants respond to HRM practices. The key contribution of the paper is to examine how different groups of migrants experience these practices, rather than simply comparing migrant and native workers as two homogeneous groups. The paper presents data from the food manufacturing sector in the UK. In total, 88 semi-structured interviews were conducted with operations managers, HR managers, union convenors and workers on permanent, temporary and agency contracts. In addition, data from informal interviews and observation at five companies are presented.     

The Role of 'Good Conversation' In Strategic Control

Most current writers on strategic control, whether from the rational planning or processual schools, agree on the importance of dialogue and debate between the interested parties to the control process. This is particularly so when strategic control is regarded in a ‘warning bell’ sense, responding to a signal that all is not going according to plan, rather than as a behavioural constraint or as an element of agency theory practice. This paper advances a normative framework for ensuring the effectiveness of such discussions based on Bird's notion of a ‘good conversation’. Bird argued that the discussion of business ethical problems should be vocal, reciprocating, issues-oriented, rational, imaginative, and honest. It is argued here that these characteristics should also apply to the discussions within the strategic control process if the process is not to be dysfunctional.     

Arbitrage and equilibrium in economies with infinitely many commodities

An ‘arbitrage opportunity’ for a class of agents is a commodity bundle that will increase the utility of any of the agents and that has non-positive price. The non-existence of ‘arbitrage opportunities’ is necessary and sufficient for the existence of an economic equilibrium. A bundle is ‘priced by arbitrage’ if there is a unique price that it can command without causing an ‘arbitrage opportunity’ to exist. For economies that have infinitely many commodities, appropriate notions of ‘arbitrage opportunities’ and ‘bundles priced by arbitrage’ depend on the continuity of agents’ preferences. This paper develops these notions, thereby providing a foundation for recent work in financial theory concerning arbitrage in continuous-time models of securities markets.     

Accounting and business economics traditions in the Netherlands

Until the 1970s Dutch accounting theorists generally showed a strong inclination towards the formulation of deductive theories. A set of different disciplines, all related to the problems of the business firm, made up a whole called ‘bedrijfseconomie’ (business economics). The theory of value, which was tantamount to the theory of replacement value, was without doubt the core of ‘bedrijfseconomie’. This paper elaborates on the changes in contents and consequences of this theory of replacement value during the second part of this century. Furthermore three other technical aspects of the accounting part of business economics will also be discussed: social accounting and reporting, translation of foreign currencies, and intangibles, especially goodwill. Since the seventies the construct of ‘bedrijfseconomie’ has fallen apart. Each discipline formerly belonging to it, has independently found its tie-up with the respective international scientific developments. ‘Bedrijfseconomie’ has lost its significance as a comprehensive academic discipline.     

PROFESSIONALIZATION AND BRITISH MANAGEMENT PRACTICEPROFESSIONALIZATION AND BRITISH MANAGEMENT PRACTICE: CASE EVIDENCE FROM MEDIUM-SIZED FIRMS IN TWO INDUSTRIAL SECTORS*

High levels of occupational specialization, problems of cross-functional integration and distinct bureaucratic tendencies have traditionally been seen as problems endemic to British management practice. Over the last decade, these problems are expected to have disappeared - or at least diminished - as major developments in management and organizational theory, as well as changing economic circumstances, have redirected management thinking towards ‘new’ ideas of flatter, simpler organizational structures, increased flexibility and decentralization, improvements in the quality of inter-functional relations and the like. Yet, despite these developments, there is comparatively little research that has investigated actual patterns of change within management and, in particular, what is happening in what could be regarded as the mainstream of British industry - namely, ‘ordinary’, medium-sized firms operating in ‘traditional’ industrial sectors. Moreover, rarely does such research focus upon the implications of management change for the strategies of professionalization adopted by competing specialist occupational groups within management. This paper sets out to help fill these gaps, by reporting the findings from case studies of four such firms, taking into account the particular contexts and historical circumstances that have helped shape any such change and drawing out the key influences on changed management practice.     

In what sense ‘regional development?’: entrepreneurship,underdevelopment and strong tradition in the periphery

This paper explores whether entrepreneurship can help less successful regions to improve their regional economic situation, without all the benefits that entrepreneurship brings when being ‘stripped out’ to more successful regions. The paper uses the idea that peripheral regions possess qualities of tradition and underdevelopment, and that these help to anchor new firms into these regions, resistant to their concentration in core regions. The paper explores whether particular entrepreneurial events can be regarded as ‘densifying’ the regional entrepreneurial environment, thereby making a positive contribution to its economic development. The paper explores the role of these negative anchors to the entrepreneurial events and the densification process by following a sequence of high-technology spin-out firms in the North East of England. Using a realist methodology attempting to interview all the firms within the sequence which could be found, the paper discovers that quite positive advantages exist within these negative qualities.The paper then considers whether these processes, such as plant closure, might drive entrepreneurship in all regions.     

Entrepreneurship and Firm Boundaries: The Theory of A Firm

abstract In this paper, we consider how a better understanding of entrepreneurial activities can help explain how firm and industry boundaries change over time and how a more comprehensive understanding of boundary setting can explain where entrepreneurial activities are directed. We start from the premise that while entrepreneurs believe themselves to have superior ideas in one or multiple parts of the value chain, they are characteristically short of cash, and of the ability to convince others to provide it. This premise motivates a simple model in which the entrepreneur has a value‐adding set of ideas for ‘upstream’ and ‘downstream’ parts of a value chain, as well as for the ways to make these two parts of the value chain work better when joined under unitary control. Assuming that the entrepreneur's objective is to maximize her wealth, we observe that even in the presence of transactional risks or other factors that might make integration preferable to specialization, initial scope depends also on relatively unexplored factors such as (a) how severe the entrepreneur's cash constraint is, and (b) how much value the entrepreneur's ideas add at each part of the value chain. Entrepreneurs will focus on the areas that provide the maximum profit yield per available cash – a criterion which implies that scope choices depend on cash availability and the depth of the demand for the new idea along the value chain. We also note that entrepreneurs make money not only from the operating profits of their firms, but also from the appreciation of the assets the firm has accumulated. This consideration can change the optimal choice of the firms’ boundaries, as entrepreneurs must be sensitive to choosing the segment that will enable them to benefit not only in terms of profit, but also in terms of asset appreciation. We propose that, in the entrepreneurial context especially, it is helpful to focus on the multiple considerations affecting the choice of boundaries for ‘a’ firm – the context faced by an individual entrepreneur – rather than on generic considerations affecting ‘the’ (representative) firm. Scope choices reflect the entrepreneur's own theory of ‘how to make money’.     

Translating macro-ideas into micro-level practices: The role of social interactions

Translation studies have conceptualized language, editing and meaning in the adoption of new ideas or policies, but left the role of interpersonal relationships largely unexplored. This paper contributes to translation theory by using insights from social exchange theory to analyze the role of social interactions in translation. Our case is the translation of the macro-idea of ‘activation’ in practices of sickness absence management within Dutch and Danish hospitals. The study reveals that the translation of this macro-idea into micro-practices varies along with the local managers’ positive or negative interpretation of social interactions with their sick-listed employees. The findings thus suggest a crucial role for interpersonal relationships in explaining meaning, reciprocity and outcomes of translation. The findings are used to develop a model of how macro-ideas are related to micro-practices via mechanisms of social exchange.
