Supporting ALARP decision making by cost benefit analysis and multiattribute utility theory

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.     

A genre-theoretic approach to financial reporting research

A genre is a category of texts marked out by the conventions employed in their production. A genre-theoretic approach draws out the complex, subtle and elusive nature of financial reporting as communication. It provides scope for examining the features of the reporting process that contribute to its complexities and subtleties in a systematic, comprehensive and integrated way, embracing both technical and social dimensions. This paper discusses aspects of genre theory, as employed in discourse analysis, and their application to financial reporting. Relevant features of the approach include financial statement composition as a challenging process; knowing users; an engaged discourse community; situated communication; intertextuality; and structural dynamism. A genre-based approach has a number of implications for financial reporting research, at both methodological and substantive levels, which are explored in the paper, and may ultimately offer the potential for integrating market-based and interdisciplinary work together with the best of the classical tradition.

Shape up or ship out? Employment discrimination against the overweight

Increasing health care insurance costs have focused employer attention on health-related factors in employee recruitment and retention. One such factor is weight. Employers have argued that overweight employees are absent more often, are more susceptible to on-the-job injuries and illnesses, and are less productive than others. They have also contended that overweight employees present poor role models and may cause “negative reactions” by others. Although no federal law addresses employee obesity specifically, a number of laws prohibiting other forms of discrimination present potentially litigious situations. This article reviews the background and legal framework of discrimination against the overweight and offers some guidelines for avoiding such charges.     

“Do You Use English in Your Daily Life?” Undergraduate Students’ Perceptions of Their Extramural Use of English

The aim of this research is to analyse the students’ perceptions about their extramural use of English, comparing undergraduates studying their degree in English (EMI) with those studying theirs in their native language (non-EMI) within a span of five academic years. Data collected from a Spanish University suggest that the students´s interest and perception of their possibilities of working abroad in English differ. Results also reveal key differences in the use of extramural English and suggest that exposure to reading books or watching English-language films will eventually contribute to the formation of global mindset in students. The trend of the importance of English during a five year span is also considered, for both strands of students. This study makes a contribution in the field of teaching in international business settings for high education institutions.     

Institutionalized Communication in Markets and Firms

How markets and firms function is critically related to what knowledge and information is exchanged between whom, how quickly. Exchange of (symbolic) information needs to be properly institutionalized in order to be understood by others, on the one hand, but, on the other hand, cannot avoid being ambiguous to some degree as well (Dolfsma et al. 2011 Dolfsma, Wilfred, John Finch, and Robert McMaster. 2011. “Identifying Institutional Vulnerability: The Importance of Language, and System Boundaries.” Journal of Economic Issues 45 (4): 805–818.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Ambiguity allows for the dissent that allows for innovation in the broadest sense of the term. Institutionalization of communication is community-specific. The tension between institutionalization of and ambiguity in communication explains why innovations cannot depart too much from what is known and accepted in a community to be (ultimately) accepted as a legitimate novelty. The view of markets and firms as settings for institutionalized communication and knowledge exchange offers a perspective that institutional economists are well positioned for to offer insights on.     

Gobierno corporativo,financiamiento y género: un estudio de las pymes emisoras de títulos en los mercados de valores argentinos

The aim of this work is to study corporate governance (CG) in small and medium enterprises (SMEs) from a gender perspective. In particular, we study the participation of women in ownership, management (board and senior management) and external audit in SMEs participating in the Argentinean Securities Market. The results show that participation of women in ownership and in external audit has a significant relationship with financing decisions. However, we do not find evidence of relations among different levels of GC and gender.     

Extending multi-tenant architectures: a database model for a multi-target support in SaaS applications

Multi-tenant architectures (MTAs) are considered a cornerstone in the success of Software as a Service as a new application distribution formula. Multi-tenancy allows multiple customers (i.e. tenants) to be consolidated into the same operational system. This way, tenants run and share the same application instance as well as costs, which are significantly reduced. Functional needs vary from one tenant to another; either companies from different sectors run different types of applications or, although deploying the same functionality, they do differ in the extent of their complexity. In any case, MTA leaves one major concern regarding the companies’ data, their privacy and security, which requires special attention to the data layer. In this article, we propose an extended data model that enhances traditional MTAs in respect of this concern. This extension – called multi-target – allows MT applications to host, manage and serve multiple functionalities within the same multi-tenant (MT) environment. The practical deployment of this approach will allow SaaS vendors to target multiple markets or address different levels of functional complexity and yet commercialise just one single MT application. The applicability of the approach is demonstrated via a case study of a real multi-tenancy multi-target (MT²) implementation, called Globalgest.
