Abstract

Extreme value theory (EVT) holds promise for advancing the assessment and management of extreme financial risks. Recent literature suggests that the application of EVT generally results in more precise estimates of extreme quantiles and tail probabilities of financial asset returns. This article assesses EVT from the perspective of financial risk management. The authors believe that the recent optimism regarding EVT may be appropriate but exaggerated, and that much of its potential remains latent. They support their claim by describing various pitfalls associated with the current use of EVT techniques, and illustrate how these can be avoided. In conclusion, the article defines several specific research directions that may further the practical and effective application of EVT to risk management.

Abstract

The conveyance of aggressive chemical liquors is probably one of the most difficult and costly problems facing industry today. The problem has special emphasis in the sector of process piping systems where elevated temperatures, high pressures and flow rates tend to intensify the corrosive action. Add to this the factor of all‐too‐frequent changes in process technology and you have a situation where installed piping can be obsolete shortly after its commissioning.

Abstract

It has been well established that organizations often need to restructure themselves to meet new technological challenges. We review the organizational impact of a recent technological development, sometimes referred to as Web 2.0 that enables users to leverage the Internet and generate “user-generated content” by acting as a supplier, co-producer, or even innovator of products and services. We draw on the social studies of technology, including actor-network theory to develop a conceptual understanding of how this phenomenon is challenging deeply entrenched mental models among managers and management theorists as well as problematizing the way organizational boundaries are conventionally drawn.

Abstract

Workplace violence is a serious problem within the National Health Service (NHS). To combat this and to reduce the incidence of abuse and aggression shown to staff, a zero tolerance public campaign was introduced in 2007 within the UK. The campaign endorsed employer‐led zero tolerance policies, despite any evidence of the effectiveness of this approach and concerns that it is discriminatory and denies health care to those who most need it. Decisions to exclude patients from GP registers are subject to varied interpretations regarding what is deviant behaviour and the blacklisting of patients is unregulated and subject to ambiguity. Furthermore, staff training programmes, which emphasise de‐escalation strategies, have not proven to be effective and can even increase violent incidences. Initiatives to provide safe havens for those excluded, while initially believed to be effective, raise many ethical arguments about the ‘ghettoising’ of health care for those already socially excluded. Research is needed into these centres in the hope of providing some of the answers, particularly around the triggers of violence, how violence is perceived and how it can be prevented.

Abstract

From a regulatory point of view, as explained by Dimson and Marsh [1994, 1995], the amount of capital required by a financial institution to ensure an acceptably small probability of failure should depend on the risk associated with the assets detained in its portfolio. Dimson and Marsh [1994] conduct an empirical study on long and short equity trading books of securities firms acting as market makers. They consider different existing regulations: the comprehensive approach, as applied in the United States by the Securities and Exchange Commission; the building‐block approach, as proposed by the Basle Committee on Banking Supervision, and incorporated in the European Community [1992] Capital Adequacy Directive (CAD); and the portfolio approach, which in the U.K. forms part of the rules of the Securities and Futures Authority [1992]. All three methods are compared via the position risk requirement (PRR) that determines the amount of capital that financial institutions have to put aside. As shown by the authors in their empirical study, the methods proposed by the international regulators are barely related to the risk of the portfolios! Only for the national U.K. rules, the PRR and the risk of a portfolio show positive correlation.

Abstract

Fat‐tailed distributions have been found in many financial and economic variables ranging from forecasting returns on financial assets to modeling recovery distributions in bankruptcies. They have also been found in numerous insurance applications such as catastrophic insurance claims and in value‐at‐risk measures employed by risk managers. Financial applications include:

Abstract

Purpose

Teamwork has long featured in social science research. Further, with research increasingly “cross-national,” communication becomes more complex, for instance, involving different cultures, languages and modes of communication. Yet, studies examining team communicative processes that can facilitate or constrain collaboration are rare. As a cross-national European team representing varied disciplines, experiences, languages and ethnicities, we undertook to examine our communication processes with the aim to promote better qualitative research practices.

Design/methodology/approach

Viewing reflection as a tool for enhancing workplace practices, we undertook a structured reflection. We developed an empirically derived framework about team communication, then used it to analyse our interaction practices and their relative effectiveness.

Findings

The results highlighted two under-examined influences, the use of different modes of communication for different purposes and the need for face-to-face communication to address a particularly challenging aspect of research, negotiating a shared coding scheme to analyse diverse cultural and linguistic qualitative data.

Practical implications

The study offers a procedure and concepts that others could use to examine their team communication.

Originality/value

The communicative processes that can constrain and facilitate effective cross-national research team collaboration are rarely examined. The results emphasise the need for careful negotiations around language, epistemologies, cultures and goals from the moment collaboration begins in formulating a project, through applying for grant funds, to when the last paper is published – timely in a context in which such work is increasingly expected.

Abstract

Purpose

The purpose of this paper is to present the results of a Delphi study of trainers in the prevention and safer management of violence in mental health settings that sought to identify and clarify what represents best practice at a European level.

Design/methodology/approach

A Delphi method was used to garner the views of a sample of 54 trainers involved in the training of managing violence and aggression on a draft charter of best practice.

Findings

A high level of agreement was found with the suggested indicators of best practice but the levels of agreement varied in some key areas and respondents identified a series of omissions from the charter and a number of potential challenges to its implementation.

Research limitations/implications

The sample was restricted to Europe and further research is planned to seek the views of a wider sample.

Practical implications

The charter will provide a reference document for best practice in the interim.

Social implications

Its implementation will require trainers to consciously identify the ethical implications not just of the content of their training buts its overall approach.

Originality/value

The study is presently unique in its focus and context but further research in this area is underway designed to complement this study.

Abstract

This paper examines the relationship between research into the evaluation of the impact of library and information services, policy making in the field, and professional practice and education. The paper first summarises the background to a recent critical literature review undertaken on behalf of Resource: the Council on Museums, Archives and Libraries. The review was intended to identify any published evidence that Museums, Archives and Libraries are making a contributory impact to developments in the British Government’s key policy areas. Except in the field of learning, little supporting evidence was found. Methodological weakness undermined the validity of much of the related work identified by the review. After considering approaches to ensuring the impact of research on policy making, including a more appropriate publication strategy and greater face‐to‐face dialogue, the paper discusses the attitudes of LIS practitioners towards academic research and the need for closer collaboration. Finally, the paper speculates on some of the implications for LIS educators in developing future researchers better equipped to identify the contribution that libraries make, and more effective in influencing policy makers.
