Teaching future Australian information systems professionals

Teaching Information Systems (IS) to Australian tertiary students has come increasing problematic with many of them relying on a face level approach to study. This will surely affect their understanding of IS material and in turn affect their effectiveness in the workplace. This paper examines the issues behind this trend and considers Problem Based Learning (PBL) as an aid to counteract it.

Helmets for preventing injury in motorcycle riders

Background: Motorcycle crash victims form a high proportion of those killed or injured in road traffic accidents. Injuries to the head, following motorcycle crashes, are a common cause of severe morbidity and mortality. It seems intuitive that helmets should protect against head injuries but it has been argued that motorcycle helmet use decreases rider vision and increases neck injuries. This review will collate the 'current available evidence on helmets and their impact on mortality, and head, face and neck injuries following motorcycle crashes.

Objectives: To quantify the effectiveness of wearing a motorcycle helmet in reducing mortality and head and neck injury following motorcycle crashes.

Search strategy: Databases including the Cochrane Injuries Group Specialised Register, Cochrane Central Register of Controlled Trials (The Cochrane Library issue 1,2003), MEDLINE (January 1966 to February 2003), EMBASE (January 1985 to February 2003), CINAHL (January 1982 to February 2003), IRRD (International Road Research Documentation), TRANSDOC, TRIS (Transport Research Information Service), ATRI (Australian Transport Index) (1976 to Feb 2003), Science Citation Index were searched for relevant articles. Web sites of traffic and road accident research bodies including government agencies were also searched. Reference lists from topic reviews, identified studies and bibliographies were examined for relevant articles.

Selection criteria: We considered for inclusion studies that investigated a population of motorcycle riders who had crashed, examining helmet use as an intervention and with outcomes that included one or more of the following: death, head, neck or facial injury. Studies included any that compared an intervention and control group and, therefore, included any randomised controlled trials, non-randomised controlled trials, cohort, case-control and cross-sectional studies. Ecological and case series studies were excluded.

Data collection and analysis: Two reviewers independently screened reference lists for eligible articles. Two reviewers independently assessed articles for inclusion criteria. Data were abstracted by two independent reviewers using a standard abstraction form.

Main results: Fifty-three observational studies were identified of varying quality. Despite methodological differences there was a remarkable consistency in results, particularly for mortality and head injury outcomes. Motorcycle helmets appear to reduce the risk of mortality although, due to heterogeneity in study design, an overall estimate of effect was not calculated. There was some evidence that the effect of helmets on mortality is modified by speed. Motorcycle helmets were found to reduce the risk of head injury and from five well-conducted studies the risk reduction is estimated to be 72% (OR 0.28, 95%CI 0.23,0.35). Insufficient evidence was found to estimate the effect of motorcycle helmets compared with no helmet on facial or neck injuries. However, studies of poorer quality suggest that helmets have no effect on the risk of neck injuries and are protective for facial injury. There was insufficient evidence to demonstrate whether differences in helmet type confer more or less advantage in injury reduction.

Conclusions: Motorcycle helmets reduce the risk of mortality and head injury in motorcycle riders who crash, although the former effect may be modified by other crash factors such as speed. Further well-conducted research is required to determine the effects of helmets and different helmet types on mortalIty, head, neck and facial injuries. However, the findings suggest that global efforts to reduce road traffic injuries may be facilitated by increasing helmet use by motorcyclists.

Pathology of chronic achilles-tendon injuries in athletes

Overuse tendon conditions have traditionally been considered to result from an inflammatory process and were treated as such. Microscopic examination of abnormal Achilles-tendon tissues, however, reveals a non-inflammatory degenerative process. The histopathology found in surgical specimens in patients with chronic overuse Achilles tendinopathy and those with Achilles-tendon rupture are reviewed. Seminal studies suggest that so-called tendinitis is a rare condition that might occur occasionally in the Achilles tendon in association with a primary tendinosis. These data have clinical implications and require a review of the traditional classification of pathologies seen in tendon conditions, The authors recommend that nomenclature be based on histopathological findings rather than traditional hypothesis.

Research data in marketing journals

Our objective is to assess the geocentricity of research data in a selection of continentally based leading academic marketing journals. The assessment considers a six-year period, namely 2000-2005. The content analysis consisted of 811 published contributions. The empirical findings may be illustrative to other academic journals in the field of marketing. The assessment is summarised on an aggregated level and per journal title. The journal sample consists of the Australasian Marketing Journal (AMJ), the European Journal of Marketing (EJM) and the Journal of Marketing (JM) – a cross-continental assessment. We contend that the selected journals should not be considered to be dramatically different in any particular sense in the area of academic marketing journals. On the contrary, together they may be quite representative of several others as well.

Approaches to the development and maintenance of professional values, ethics and attitudes in accounting education programs

IES 4, Professional Values, Ethics and Attitudes prescribes the professional values, ethics and attitudes professional accountants should acquire during the education program leading to membership of an IFAC member body.
The purpose of this paper is to support the development of IEPS 4.1, Approaches to Developing and Maintaining Professional Values, Ethics and Attitudes. This will assist and support IFAC member bodies to discharge effectively their responsibilities to ensure that candidates for membership of an IFAC member body are equipped with the appropriate professional values, ethics and attitudes to function as professional accountants.
The IAESB believes that this paper, and the findings of the independent research team, will be of interest and benefit to IFAC member bodies, accounting educators, and others seeking to implement ethics education programs for professional accountants.

The pleasure and pain of donations

Deakin University is only 25 years old but already has a library collection of over 1 million volumes thanks, in part, to judicious seeking and acceptance of donations. This paper provides a case study of how the University has been able to quickly establish teaching and research level collections for new disciplines as well as build breadth and depth in areas already covered by the collection. Donations of formed collections, in particular, have enabled the University to build a research reputation in a number of specialist areas and to make important links with its local communities. The benefits of donations are highlighted, as are the problems that come with being offered gifts of information resources.

Ethics education for accounting students - a toolkit approach

In 2006, the International Accounting Education Standards Board (IAESB), an independent standard-setting board of the International Federation of Accountants (IFAC) released an information paper entitled Approaches to the Development and Maintenance of Professional Values, Ethics and Attitudes in Accounting Education Programs. The information paper stems from a global research project on ethics education in the accounting profession. The paper is designed to stimulate discussion and debate on the subject of ethics education and includes the provision of an Ethics Education Toolkit to encourage and assist accounting educators and member bodies of IFAC to implement ethics education programmes. Through a review of the literature, this paper considers why we should teach ethics, the types of ethics interventions that have been undertaken and the issues in teaching ethics to accountancy students. The paper then describes in detail the Ethics Education Toolkit and provides some evidence on the positive reaction of a group of students who are taught ethics, based on the principles and practice included in the toolkit.

Decentralized and robust target tracking with sensor networks

In this paper we address the problem of decentralized and robust linear filtering for target tracking using networks of (radar) sensors taking nonlinear range and bearing measurements. The algorithm introduced in this paper permits efficient data fusion from multiple sensors through a summation style fusion architecture. Moreover, we prove that the state estimation error for the linear filtering algorithm is bounded.

Analysis and implementation of swimming backward for biomimetic carangiform robot fish

The swimming backward for biomimetic carangiform robot fish is analyzed and implemented in this paper. The swimming law of the carangiform robot fish is modified according to the European Eel swimming mode based on the multiple-link structure to implement the backward motion. The motion mode difference between the eel and carangiform fish is discussed, and a qualitative kinematic analysis of the carangiform swimming in water is given to analyze the propulsion produced by the undulation of the multi-links tail. The experiments conducted demonstrate the good performance of the proposed method, and the results are given.
