Management of accounting: The case for an active role

Regulations imposed upon both the external and internal accounting reports of enterprises may evoke a variety of responses from managers ranging from the active to the passive. This paper explores the active, participatory role which managers may choose to adopt in influencing the direction of accounting regulations. Reference is made to a large number of cases arising in Europe and elsewhere which illustrate how managers have provided benefits to their businesses by actively lobbying for constructive changes in the accounting environment.     

Future of European human resource management: A contingent approach

The ability to cope with an increasingly open European Market, enhanced mobility between nation states and the threat of competition from the Far East will be highly prized organisational skills in the third millenium. Many commentators have argued that ‘Europeanisation’ (broadly defined) is an irreversible process and companies will have to cope proactively with this or perish. However, in this article we argue that many of these predictions are based on an uncritical acceptance of the ‘internationalisation’ thesis, and on subjective assessments of possible future trends — rather than on sound empirical research within strong theoretical frameworks. Accordingly, this article takes a critical look at some widely-held assumptions about internationalisation, Europeanisation and the (potential) development of European Human Resource Management (EHRM). It then goes on to suggest a framework of research which will be more able to capture future developments in EHRM and thereby facilitate more robust exchanges on strategic HRM with those companies operating in a European setting.     

Computation of determinantal subset influence in regression

One of the important goals of regression diagnostics is the detection of cases or groups of cases which have an inordinate impact on the regression results. Such observations are generally described as influential. A number of influence measures have been proposed, each focusing on a different aspect of the regression. For single cases, these measures are relatively simple and inexpensive to calculate. However, the detection of multiple-case or joint influence is more difficult on two counts. First, calculation of influence for a single subset is more involved than for an individual case, and second, the sheer number of subsets of cases makes the computation overwhelming for all but the smallest data sets.Barrett and Gray (1992) described methods for efficiently examining subset influence for those measures that can be expressed as the trace of a product of positive semidefinite (psd) matrices. There are, however, other popular measures that do not take this form, but rather are expressible as the ratio of determinants of psd matrices. This article focuses on reducing the computation for the determinantal ratio measures by making use of upper and lower bounds on the influence to limit the number of subsets for which the actual influence must be explicitly determined.     

When should there be liability for negligently causing psychiatric illness?

In March 1998 the Law Commission for England and Wales published the outcome of its review of the law on compensation of those who suffer psychiatric illness as a result of the negligence of another person. The report is largely, although not solely, concerned with work-related illness. It also reviews the literature on the incidenc and forms of psychiatric illness. It makes recommendations for legislation. This paper critically summarizes the findings of the Commission and concludes with some comments. It questions the appropriateness of common law litigation for these kinds of injury. It also comments on whether the Commission's recommendations will be implemented by Parliament and the likely impact of the proposed revision of the law upon the incidence of litigation.     

Peak performing organisations

The literature on organisational performance is riddled with measurement problems that cannot easily be solved. In contrast we argue that elite theory in terms of performance can be more easily measured by the win record of sports organisations. Accordingly, this article argues that certain organisational peak practices are key to understanding how peak performance is sustained. Through data collected from the top ten sports organisations in the world we introduce the embryonic theory of Peak Performing Organisations (PPO). Sustained PPO practices offer more robust outcomes than the genre of High Performing Organisations.     

Assessment of the Regional Economic Impacts of Catastrophic Events: CGE Analysis of Resource Loss and Behavioral Effects of an RDD Attack Scenario

We investigate the regional economic consequences of a hypothetical catastrophic event—attack via radiological dispersal device (RDD)—centered on the downtown Los Angeles area. We distinguish two routes via which such an event might affect regional economic activity: (i) reduction in effective resource supply (the resource loss effect) and (ii) shifts in the perceptions of economic agents (the behavioral effect). The resource loss effect relates to the physical destructiveness of the event, while the behavioral effect relates to changes in fear and risk perception. Both affect the size of the regional economy. RDD detonation causes little capital damage and few casualties, but generates substantial short‐run resource loss via business interruption. Changes in fear and risk perception increase the supply cost of resources to the affected region, while simultaneously reducing demand for goods produced in the region. We use results from a nationwide survey, tailored to our RDD scenario, to inform our model values for behavioral effects. Survey results, supplemented by findings from previous research on stigmatized asset values, suggest that in the region affected by the RDD, households may require higher wages, investors may require higher returns, and customers may require price discounts. We show that because behavioral effects may have lingering long‐term deleterious impacts on both the supply‐cost of resources to a region and willingness to pay for regional output, they can generate changes in regional gross domestic product (GDP) much greater than those generated by resource loss effects. Implications for policies that have the potential to mitigate these effects are discussed.     

The Evolution of Coding in Signaling Games

Signaling games with reinforcement learning have been used to model the evolution of term languages (Lewis 1969, Convention. Cambridge, MA: Harvard University Press; Skyrms 2006, “Signals” Presidential Address. Philosophy of Science Association for PSA). In this article, syntactic games, extensions of David Lewis’s original sender–receiver game, are used to illustrate how a language that exploits available syntactic structure might evolve to code for states of the world. The evolution of a language occurs in the context of available vocabulary and syntax—the role played by each component is compared in the context of simple reinforcement learning.
