Modelling soccer matches using bivariate discrete distributions with general dependence structure

In this paper copulas are used to generate bivariate discrete distributions. These distributions are fitted to soccer data from the English Premier League. An interesting aspect of these data is that the primary variable of interest, the discrete pair shots-for and shots-against, exhibits negative dependence; thus, in particular, we apply bivariate Poisson-related distributions that allow such dependence. The paper focuses on Archimedian copulas, for which the dependence structure is fully determined by a one-dimensional projection that is invariant under marginal transformations. Diagnostic plots for copula fit based on this projection are adapted to deal with discrete variables. Covariates relating to within-match contributions such as numbers of passes and tackles are introduced to explain variability in shot outcomes. The results of this analysis would appear to support the notion that playing the 'beautiful game' is an effective strategy—more passes and crosses contribute to more effective play and more shots on the goal.     

No easy solutions: lessons learned from an intervention to reduce clinic non‐attendance rates in a Scottish hospital

Hospital waiting lists and times have become the public measure of government success or failure. This research examined existing hospital outpatient capacity and considered the age‐old problem of patients who fail to attend their appointment. A reduction in did‐not‐attend (DNA) rates would maximize utilization of capacity, ensure early diagnosis and drive down waiting times. The research was designed to determine whether the introduction of outpatient letters, which included the need for positive confirmation of attendance, decreased the incidence of patient non‐attendance. Utilizing an experimental design, data gathered at two Plastic Surgery clinics were compared over two three‐month periods, pre‐ and post‐implementation. Total attendance and non‐attendance were examined in terms of new and review patients, gender and age profile. The research concludes that the intervention tested in this form can now be discounted thus allowing the exploration of subtler solutions.     

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.

Managing academic innovation in Taiwan: Towards a ‘scientific-economic’ framework

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn.     

Opening the Black Box: Corporate Codes of Ethics in Their Organizational Context

A review of the literature on Corporate Codes of Ethics suggests that whilst there exists an informative body of literature concerning the prevalence of such codes, their design, implementation and promulgation, it is also evident that there is a relative lack of consideration of their impact upon members' everyday organizational behaviour. By drawing upon organizational sociology and psychology this paper constructs a contextualist and interpretive model which seeks to enable an analysis and evaluation of their effects upon individual, group and organizational behaviour.     

Response to price and production risk: The case of Australian wheat

A model of Australian wheat grower supply response was specified under the constrainsts of price and yield uncertainty, risk aversion, partial adjustment, and quadratic costs. The model was solved to obtain area planted. The results of estimation indicate that risk arising from prices and climate have had a significant influence on producer decision making. The coefficient of relative risk aversion and short‐run and long‐run elasticities of supply with respect to price were calculated. Wheat growers' risk premium, expected at the start of the season for exposed price and yield risk, was 2.8 percent of revenue or 10.4 percent of profit as measured by producer surplus. © 2000 John Wiley & Sons, Inc.

Embedding multinational firms in regional business systems: neoliberal and social‐democratic models in Spain

The paper analyses how regional actors have mobilised to attract and retain foreign direct investment in two Spanish regions with different political approaches to the management of economic issues, including industrial relations. These regions are Madrid, the main pole of attraction of foreign direct investment in Spain, and Asturias, with a large tradition of heavy industry and a greater dependence on a small number of large employers. It finds the regions have adapted to international competition in substantially different manners and considers the alternative reasons why this might be the case, highlighting the role of organised labour both in the inward investment regimes themselves, and in shaping the nature of the different compromises they involve.
