Crossing the line : collusion or collaboration in university group work?

In both policy and practice, collusion is a perplexing area of academic integrity. Students are expected to learn to work collaboratively in university courses, yet are often required to submit assessment tasks as individuals whilst in group-work situations. This paper discusses the tension between 'collaboration' and 'collusion' in group-work and the consequences for crossing the line. Adopting a theoretical framework from Bourdieu's work (Bourdieu and Passeron, 1971; Bourdieu, 1991) on symbolic power, the notion of legitimate voice and intertextuality, this paper outlines the effects on the academic identities of 17 students found 'guilty' of collusion in one Australian university. In addition, 34 staff involved in formal disciplinary procedures were interviewed. The findings indicate that collusion is a fraught notion and not approached systematically across the university, nor with any degree of confidence by staff or students. The delineation between 'acceptable collaboration' and 'collusion' appears to be founded in shifting sands, with negative attitudes towards collaborative tasks being the main lesson learned by students.

Just 'good and bad news'? Disciplinary imaginaries of head teachers in Australian and English print media

Australian and English print media are actively engaged in producing reports that claim to find the 'best schools', the 'real state of education', and 'star head teachers'. This article considers the production of knights and dames, maverick heads and struggling schools. It argues that some of these stories are clearly the products of departmental press bureau activities and policy agendas. It shows, however, that even those stories intended to critique government policy support paradoxically a notion of the singular importance of the headship and the virtues of heroic leadership. It is suggested that the simulacrum of the heroic head works as a normative disciplinary device for performative and market practices and is singularly off-putting to both serving and aspirant school leaders.

Multi-jurisdictional merger review procedures - a better way

Corporate mergers whose effects transcend national borders have faced increasing regulation over the past few decades as more jurisdictions have developed merger laws and imposed pre-merger notification requirements. The level of regulatory response to multi-jurisdictional mergers is likely to continue to increase as even more jurisdictions contemplate the introduction of competition laws. This level of regulation now goes beyond that required to protect national economies from potentially harmful mergers and has seen burgeoning costs to business, regulators and, ultimately, the public. In recognition of this, the relatively newly formed International Competition Network has placed merger regulation at the forefront of its agenda for greater harmonisation and cooperation in competition law. This has seen, over the past three years, the development of a set of guiding principles and recommended practices for merger notification procedures designed to reduce the regulatory burden. This article evaluates these recommendations and discusses areas for further reform.

Patients' experiences of cardiology procedures using minimal conscous sedation

Aim: The study's purpose was to describe patients' experiences of minimal conscious sedation during diagnostic and interventional cardiology procedures.

Methods: Over a 6-week period, 119 consecutive patients (10% of annual throughput) from a major metropolitan hospital in Melbourne, Australia, were interviewed using a modified version of the American Pain Society Patient Outcome Questionnaire. Patients identified pain severity using a 10-point visual analogue scale and rated their overall comfort on a 6-point Likert scale ranging from very comfortable to very uncomfortable.

Results: Patients were aged 67.6 years (standard deviation 11.1), 70.8% were male, and the mean body mass index was 27.7 (standard deviation 4.8). Patients underwent diagnostic coronary angiography (67.5%), percutaneous coronary interventions (13.3%), or combined procedures (19.2%). Most patients (65%) were comfortable in the context of low-dose conscious sedation. Slight discomfort was reported by 26% of patients; 9% reported feeling uncomfortable primarily as a result of a combination of musculoskeletal pain, angina, and vasovagal symptoms experienced during the procedure. There was significant correlation (rho = .25, P = .01) between procedure length and patients' report of overall comfort, suggesting longer procedures were less comfortable for patients.

Conclusions: The minimal sedation protocol was effective for the majority of patients; however, 9% of patients experienced significant discomfort related to preexisting conditions, highlighting the need for individual patient assessment before, during, and after the procedure.

Risk management and ethical environment : effects on internal audit and accounting control procedures

This study examines the impact of the scope of risk management and ethical environment on internal audit activities and the quality of accounting control procedures (ACPQ). The conceptual framework for the study is guided by COSO’s frameworks on internal controls and enterprise risk management and data from a questionnaire survey of 64 Australian firms are analysed using a structural equation model. The results of the study support that (1) internal audit activities have a significant intervening effect on the relationship between the scope of risk management and ACPQ, and (2) a direct and positive relationship exists between ethical environment and ACPQ. Our findings suggest that widening the scope of risk management activities do not directly improve ACPQ, but that it leads to more extensive internal audit activities and in turn such activities promote better ACPQ. Further, the results indicate that fostering a more ethical environment directly leads to higher ACPQ. These results have implications for the design of internal controls, namely with respect to the role of internal audit activities and ethical environment in enhancing ACPQ.

Quality of internal control procedures : antecedents and moderating effect on organisational justice and employee fraud

Purpose – This study aims to bring together theoretical concepts from the organizational justice, internal control and fraud literature to develop two distinct models relating to employee fraud and the quality of internal control procedures (ICP), respectively.

Design/methodology/approach – Survey data from 64 Australian firms were used to develop the two models. The first model was tested using a logistic regression analysis, and the second model was tested using a multiple regression analysis.

Findings – The first model reveals that the quality of ICP has a moderating effect on the relationship between perceptions of organizational justice and employee fraud. The second model indicates that ICP quality is significantly and positively related to three key organizational factors: the corporate ethical environment, the extent of risk management training of staff, and the internal audit (IA) activity level.

Practical implications – Risk management strategies relating to employee fraud will need to pay greater attention to organizational factors that affect both perceptions of justice at the workplace and ICP quality, including fostering a more ethical and equitable work environment, increasing IA activities and staff training in risk management.

Originality/value – Using the fraud triangle framework, this study extends previous literature by providing empirical evidence on the role of organizational justice and ICP regarding employee fraud.

The optimisation of ultrasonic cleaning procedures for dairy fouled ultrafiltration membranes

Ultrafiltration (UF) of whey is a major membrane based process in the dairy industry. However, commercialization of this application has been limited by membrane fouling, which has a detrimental influence on the permeation rate. There are a number of different chemical and physical cleaning methods currently used for cleaning a fouled membrane. It has been suggested that the cleaning frequency and the severity of such cleaning procedures control the membrane lifetime. The development of an optimal cleaning strategy should therefore have a direct implication on the process economics. Recently, the use of ultrasound has attracted considerable interest as an alternative approach to the conventional methods. In the present study, we have studied the ultrasonic cleaning of polysulfone ultrafiltration membranes fouled with dairy whey solutions. The effects of a number of cleaning process parameters have been examined in the presence of ultrasound and results compared with the conventional operation. Experiments were conducted using a small single sheet membrane unit that was immersed totally within an ultrasonic bath. Results show that ultrasonic cleaning improves the cleaning efficiency under all experimental conditions. The ultrasonic effect is more significant in the absence of surfactant, but is less influenced by temperature and transmembrane pressure. Our results suggest that the ultrasonic energy acts primarily by increasing the turbulence within the cleaning solution.
