Hormones down under: Hormone therapy use after the Women's Health Initiative

Aims:  The primary objective was to describe the usage pattern of hormone therapy (HT) in a sample of urban Australian women in 2001 and to assess the characteristics of users vs. non-users. The second objective was to determine whether there had been any change in usage since the publication of the results of the combined oestrogen plus progestagen arm of the Women's Health Initiative (WHI) in 2002. Methods:  A cohort of 374 postmenopausal women aged 50–80 years participated in this substudy of the LAW (Longitudinal Assessment of Ageing in Women) project: a 5-year multidisciplinary, observational study. Participants completed an annual medical assessment including details of the use of HT and the reasons for use, as well as demographic and psychosocial data. Results:  In December 2001, 30.8% of the participants were using HT, whereas 55.4% were ever users. The management of vasomotor symptoms and mood disturbance were the primary reasons for use. Of those who had been using HT in December 2001 (24.4%) women ceased using HT in the 3 months following publication of the WHI results. The percentage of women using HT in December 2003 (13.9%) was less than half of that of December 2001. Conclusion:  The rate of HT use and the reasons for use, in 2001 in Brisbane was similar to that of other Australian regions. Usage of HT decreased since the publication of the WHI results in 2002 which may reflect changing attitudes by patients and practitioners regarding HT.

An Investigation of Organic Factors in the Neuropsychological Functioning of Patients with Borderline Personality Disorder

The hypothesis to be tested in this study was that the cognitive deficits that have been documented in patients with Borderline Personality Disorder (BPD) are largely the consequence of organic insult, either developmental or acquired. Using a cross–sectional design, 80 subjects (males and females) who met the criteria for BPD participated in the study. They completed a battery of neuropsychological tests and a comprehensive interview assessing organic status as well as measures of the potentially confounding factors of current levels of depression and anxiety. It was expected that BPD-patients with a probable history of organic insult would perform significantly worse than would BPD patients without such a history. Analyses of the results provided partial support for the hypothesis. Subjects with both BPD and a history of organic insult were significantly more impaired on several measures including measures of attention than were BPD only subjects. The results suggested that the impaired cognitive performance of persons diagnosed with BPD may, in part, be attributed to organic factors.

The certainty of tax in insolvency : where does the ATO fit?

There are several ways that the Commissioner of Taxation may indirectly obtain priority over unsecured creditors. This is contrary to the principle of pari passu, a principle endorsed by the 1988 Harmer Report as one that is a fundamental objective of the law of insolvency. As the law and practice of Australia's taxation regime evolves, the law is being drafted in a manner that is inconsistent with the principle of pari passu. The natural consequence of this development is that it places at risk the capacity of corporate and bankruptcy laws to coexist and cooperate with taxation laws. This article posits that undermining the consistency of Commonwealth legislative objectives is undesirable. The authors suggest that one means of addressing the inconsistency is to examine whether there is a clearly aligned theoretical basis for the development of these areas of law and the extent that alignment addresses these inconsistencies. This forms the basis for the recommendations made around such inconsistencies using statutory priorities as an exemplar.

One approach to finding evidence for the effectiveness of scientific visualisations in high school physics and chemistry education

Enormous amounts of money and energy are being devoted to the development, use and organisation of computer-based scientific visualisations (e.g. animations and simulations) in science education. It seems plausible that visualisations that enable students to gain visual access to scientific phenomena that are too large, too small or occur too quickly or too slowly to be seen by the naked eye, or to scientific concepts and models, would yield enhanced conceptual learning. When the literature is searched, however, it quickly becomes apparent that there is a dearth of quantitative evidence for the effectiveness of scientific visualisations in enhancing students’ learning of science concepts. This paper outlines an Australian project that is using innovative research methodology to gather evidence on this question in physics and chemistry classrooms.

Body composition and appetite : fat-free mass (but not fat mass or BMI) is positively associated with self-determined meal size and daily energy intake in humans

The idea of body weight regulation implies that a biological mechanism exerts control over energy expenditure and food intake. This is a central tenet of energy homeostasis. However, the source and identity of the controlling mechanism have not been identified, although it is often presumed to be some long-acting signal related to body fat, such as leptin. Using a comprehensive experimental platform, we have investigated the relationship between biological and behavioural variables in two separate studies over a 12-week intervention period in obese adults (total n 92). All variables have been measured objectively and with a similar degree of scientific control and precision, including anthropometric factors, body composition, RMR and accumulative energy consumed at individual meals across the whole day. Results showed that meal size and daily energy intake (EI) were significantly correlated with fat-free mass (FFM, P values ,0·02–0·05) but not with fat mass (FM) or BMI (P values 0·11–0·45) (study 1, n 58). In study 2 (n 34), FFM (but not FM or BMI) predicted meal size and daily EI under two distinct dietary conditions (high-fat and low-fat). These data appear to indicate that, under these circumstances, some signal associated with lean mass (but not FM) exerts a determining effect over self-selected food consumption. This signal may be postulated to interact with a separate class of signals generated by FM. This finding may have implications for investigations of the molecular control of food intake and body weight and for the management of obesity.

Peer passenger identity and passenger pressure on young drivers' speeding intentions

Young drivers, aged 17 to 24 years, have the highest fatality rate in Australia. It is believed that part of this risk is due to pressure from peer passengers to engage in speeding; which may be active (i.e., verbal encouragement) or passive (i.e., perceived pressure on the part of the driver). The Theory of Planned Behaviour (TPB) was used to investigate this impact of peer passengers on young drivers, particularly the influence of the type of peer pressure and a driver’s level of identification with their passengers. A scenario-based questionnaire was constructed, informed by focus groups and pilot studies, and distributed to university students (N = 398). The questionnaire measured participants’ intentions and the TPB constructs, including two components of perceived behaviour control, within a baseline scenario as well as an experimental scenario in which the variables of type of pressure and identification were manipulated. Consistent with the hypotheses, the study found that attitudes and self-efficacy significantly predicted intentions over and above the variance explained by the sociodemographic variables of age, gender, self-esteem, sensation seeking, as well as past behaviour and exposure. Across the scenarios, attitudes explained between 4.3% and 14.5%, while self-efficacy to refrain from speeding explained between 4.9% and 17.1%, of the unique variance in intentions to speed. However, contrary to expectations, intentions to speed were found to be higher in the “no passenger” than “passenger present” conditions, although this finding is not completely inconsistent with recent literature. A high level of identification with passengers led to higher intentions to speed than low identification as expected, but, inconsistent with expectations, different types of pressure (i.e., active versus passive) did not influence intentions to speed.

Capstones : transitions and professional identity

The literature identifies transition as a key objective for capstone experiences. Capstones should take account of the particular needs of final year students by assisting them to transition from their student to their professional identity. The authors are currently completing an Australian Learning and Teaching Council (ALTC) funded project, “Curriculum Renewal in Legal Education: articulating final year curriculum design principles and a final year program”, which seeks to achieve curriculum renewal for legal education in the Australian context through the articulation of a set of curriculum design principles for the final year and the design of a transferable model for an effective final year program. The project has investigated the contemporary role of capstones in assisting transition out by reviewing the relevant literature and considering feedback from a project reference group, a final year student focus group and a recent graduate’s focus group. Analysis of this extensive research- and evidence-base suggests that capstone experiences should support transition through: • Assisting students to develop a sense of professional identity; • Consolidating students’ lifelong learning skills; • Providing opportunities for consolidation of career development and planning processes; • Enabling students to enhance professional skills and competencies; and • Preparing students as ethical citizens and leaders. This paper will examine the role of capstones in assisting students to transition to their professional identity and will propose learning and teaching approaches and assessment of learning methods that support transition out.

Exercise for breast cancer survivors: bridging the gap between evidence and practice

Evidence supporting the benefits of exercise following the diagnosis of breast cancer is overwhelming and compelling. Exercise reduces the severity and number of treatment-related side effects, optimizes quality of life during and following treatment, and may optimize survival. Yet, exercise does not uniformly form part of the standards of care provided to women following a breast cancer diagnosis. This commentary summarizes the evidence in support of exercise as a form of adjuvant treatment and identifies and discusses potential issues preventing the formal integration of exercise into breast cancer care. Proposed within the commentary is a model of breast cancer care that incorporates exercise prescription as a key component but also integrates the need for surveillance and management for common breast cancer treatment-related morbidities, as well as education. While future research evaluating the potential cost savings through implementation of such amodel is required, a committed, collaborative approach by clinicians, allied health professionals, and researchers will be instrumental in bridging the gap between research and practice.

Demanding a change : time to act on statutory demands

The statutory demand procedure has been a part of our corporate law from its earliest modern formulations and it has been suggested, albeit anecdotally, that under the current regime, it gives rise to more litigation than any other part of the Corporations Act. Despite this there has been a lack of consideration of the underlying policy behind the procedure in both the case law and literature; both of which are largely centred on the technical aspects of the process. The purpose of this article is to examine briefly the process of the statutory demand in the context of the current insolvency law in Australia. This paper argues that robust analysis of the statutory demand regime is overdue. The paper first sets out to discover if there is a policy justification for the process and to articulate what that may be. Second, it will briefly examine the current legislation and argue that the structure actually encourages litigation which is arguably undesirable in the context of insolvency. In particular we will ask if the current rigid legal regime is appropriate for dealing efficiently with the highly charged atmosphere of contested insolvency. Third, it will examine suggested reforms in this area as to whether they might be a way forward.

Designing a capstone experience for Australian legal education

Literature suggests that universities, and law schools in particular, are not engaging final year students in a genuine capstone experience which supports the development of their professional identity and their transition out of university. Students in their final year also face significant transition issues which are just as challenging as those facing first year students entering the tertiary environment (Jervis & Hartley, 2005, 314)...

The capstone experience in law

An effective capstone experience provides closure through: Supporting students to synthesise their learning in the program by building upon the knowledge, skills and capability development that has taken place over the entirety of the curriculum; Providing enhanced opportunities for students to reflect on their personal and professional development over the course of their legal education experience and how that prepares them for their future professional and personal lives; Assisting students to attain an understanding of what it means to be a graduate of the discipline and begin to develop a professional identity.

Teacher educators mediating curricular reform : anticipating the Australian curriculum

Many education systems are experiencing a re-scaling and consolidation of governance through rolling national agendas of standardisation and centralisation. This paper considers the case of Australia as it moves towards implementing its first national curriculum, to explore how teacher educators plan to retain pedagogical space for debate, diversity and contestation of such systemic curricular reform. This paper reports on an interview study conducted with nine teacher educators across the four curriculum areas included in the first wave of the Australian Curriculum: English, Science, Mathematics and History. The analysis reveals how teacher educators reported professional dilemmas around curricular design, and planned to resolve such dilemmas between the anticipated changes and their preferences for what might have been. While different curricular areas displayed different patterns of professional dilemma, the teacher educators are shown to construe their role as one of active curriculum mediators, who, in recontextualising curricular reforms, will use the opportunity to reinsert both residualised and emergent alternatives in their students’ professional value sets. The study also identifies a new set of dilemmas emerging around the politicisation and standardisation of curriculum, and its impact on the teaching profession and teacher educators.
