Formalising Workflow: A CCS-inspired Characterisation of the YAWL Workflow Patterns

We present work concerning the formal specification of business processes. It is of substantial benefit to be able to pin down the meaning of business processes precisely. This is an end in itself, but we are also concerned to do so in order that we might prove properties about the business processes that are being specified. It is a notable characteristic of most languages for representing business processes that they lack a robust semantics, and a notable characteristic of most commercial Business Process Management products that they have no support for verification of business process models. We define a high-level meta-model, called Liesbet , for representing business processes. The ontological commitments for Liesbet are sourced from the YAWL workflow patterns, which have been defined from studies into the behavioural nature of business processes. A formal characterisation of Liesbet is provided using Milner’s Calculus of Communicating Systems (CCS). In this article, we omit some of the technical details of this characterisation and instead present the essential features by means of an abstract machine language, called LCCS. We also explain how we have facilitated the verification of certain properties of business processes specified in Liesbet , and discuss how Liesbet supports the YAWL workflow patterns. We include a simple three-part example of using Liesbet .     

Are Men Always Picked Over Women? The Effects of Employment Equity Directives on Selection Decisions

This study replicates and extends previous work by Oppenheimer and Wiesner [1990, Sex discrimination: Who is hired and do employment equity statements make a difference? Proceedings of the 11th Annual Conference of the Administrative Sciences Association of Canada, Personnel and Human Resources Division], and examined the effects of minority qualifications on hiring decisions, the effects of employment equity directives when minority candidates are less qualified and the effects of different types and strengths of employment equity directives on hiring decisions. The results indicate that when employment equity is in place, people are increasingly more likely to hire underrepresented group members, to the extent that they are more qualified. Men appear to be treated in a positively biased manner, and are more likely to be hired when they are less qualified. Women are less likely to be hired when they are under-qualified, and in the absence of employment equity directives or when there is a suggestion that women are underrepresented. Moreover, when␣employment equity directives are strengthened, there appears to be a subtle backlash for women but not for men. Eddy S. Ng is an assistant professor at Trent University.

Ethical Exemplification and the AICPA Code of Professional Conduct: An Empirical Investigation of Auditor and Public Perceptions

This research applies the impression management theory of exemplification in an accounting study by identifying and measuring differences in both auditor and public perceptions of exemplary behaviors. The auditors were divided into two groups, one of which reported self-perceptions (A-S) while the other group reported their perceptions of a typical auditor (A-O). There were two separate public groups, which gave their perceptions of a typical auditor and were divided based on their levels of accounting sophistication. The more sophisticated public group was comprised of bank loan officers (LO) while the less sophisticated public group consisted of investment club members (IC). Comparisons were made on 30 behaviors contained in the AICPA Code of Professional Conduct, which served as the basis for the research instrument. Profile analysis, a special form of MANOVA technique, was used to analyze the results. A-S perceptions were the highest of the four treatment levels and were significantly higher (i.e., more exemplary) than the perceptions of both the A-O and LO groups. The more sophisticated user group (LO) provided the lowest perceptions of the four treatment levels. For at least four of the six measures, the LO treatment group perceived the typical auditor to be less exemplary than both the IC and A-O treatments. There were no differences in perceptions between the A-O group and IC. Additional analysis revealed that auditors overrated the degree to which the public relied on financial statements. However, both public groups reported a reasonably high level of reliance on financial statements when making decisions. Philip A.

Elderly consumers: problems and behaviours

The purpose of this study was to explore older consumers' problems and behaviour. Data were collected by interviewing. Responses of 150 older Wisconsin residents were analysed using chi square to determine significant differences in consumer problems and behaviour related to the demographic variables: age, sex, place of residence, marital status and education. The distribution of responses was most frequently influenced by marital status. The demographic variables of age, sex and place of residence were also found to influence the response distribution, although less frequently than marital status; there were no significant differences in responses by education. Based on the findings, recommendations are made for consumer education programmes designed specifically for older persons.
