Still plucking figures out of the air? Markarian and the affirmation of the instinctive synthesis

The High Court of Australia recently had the opportunity to reconsider the appropriate sentencing methodology to be adopted in the sentencing of offenders under Australian criminal law in the case of Markarian v The Queen. The High Court had to decide whether to continue with the instinctive synthesis approach to sentencing or a process that exposed in greater clarity the basis upon which sentencing was to occur. Ultimately, a majority of the Court favoured the continuance of the instinctive synthesis approach to sentencing in criminal cases. The article will consider the decision in Markarian and the implications that it will have for the sentencing of offenders in the States and Territories of Australia.

A framework for material management in the building demolition industry

Conventional mechanical building demolition produces numerous solid wastes, most of which are sent to landfill directly and severely degrade the living environment. Just-in-time building demolition has been developed recently with a management strategy to facilitate waste reuse. Procurement management plays a significant role in just-in-time building demolition. In particular, the demolition tendering selection needs to consider contractors' environmental performance in addition to project costs. Moreover, the flow of building materials in a demolition project may be regarded as a supply chain involving the building owner, demolition contractor and material demanders. This paper develops a framework for salvaged materials management in the emerging demolition industry. The research is to promote the recycling and reuse of building demolition materials in order to achieve better environmental and financial performance for building demolition projects.

The federal solution to ethnic conflicts

Conflicts over ethnic homeland rule, the right to territorial autonomy, and even nation-statehood have been played out in Asia, where it has been debated whether federalism is the best system to reduce or contain ethnic conflicts. The international community has questioned whether the multinational federalism of Spain and Canada offers a successful model for Asia.

Toward a receiver-based theory of knowledge sharing

Managers and researchers alike have sought new ways to address the challenges of sharing dispersed knowledge in modern business environments. Careful consideration by sharers of receivers' knowledge needs and behaviours may improve the effectiveness of knowledge sharing. This research examines how sharers react to their perceptions of receivers' knowledge needs and behaviours when making choices relating to sharing knowledge. The focus of this article is to propose and empirically explore a theoretical framework for a study of the role of the receiver in knowledge sharing--receiver-based theory. Data collected from two case studies highlight a key role played by perceived receiver knowledge needs and behaviours in shaping sharer choices when explicit knowledge is shared. A set of receiver influences on knowledge sharing is provided that highlights key receiver and sharer issues. The paper concludes that companies should develop better ways to connect potential sharers with receivers' real knowledge needs. Further, the findings suggest that sharing on a need-to-know basis hinders change in organisational power structures, and prevents the integration of isolated pockets of knowledge that may yield new value.

Electronic contracting in aircraft aftercare: A case study

Distributed systems comprised of autonomous self-interested entities require some sort of control mechanism to ensure the predictability of the interactions that drive them. This is certainly true in the aerospace domain, where manufacturers, suppliers and operators must coordinate their activities to maximise safety and profit, for example. To address this need, the notion of norms has been proposed which, when incorporated into formal electronic documents, allow for the specification and deployment of contract-driven systems. In this context, we describe the CONTRACT framework and architecture for exactly this purpose, and describe a concrete instantiation of this architecture as a prototype system applied to an aerospace aftercare scenario.

`Don`t call me sweetie!` patients differ from nurses in their perceptions of caring

Effective nursing care relies on congruent nurse-patient perception of needs. This study used Q methodology to compare nurses' and patients' perceptions of important nursing care behaviour. Q methodology applies statistical analysis to qualitative data through a technique of comparative rating using a forced choice format. The Care Q Sort, comprising fifty statements of nursing behaviour, was administered to nurses and patients from medical wards. Participants ranked the nursing behaviours from most to least important. Analysis was completed on 74 rankings. There was agreement for many behaviours but bimodal distributions for nurses' scores for some statements which may be attributable to different professional levels. An additional open comments section provided an experiential dimension to the research results. The findings will inform nursing practice and patient care planning.

High performance low-energy buildings

The era of legislation and creditable methods towards producing sustainable buildings is upon us. Yet, a major barrier to achieving environmental responsive design is in the lack of available information at the programming or pre-design phases of a project. The review and evaluation of climate as well as energy-efficient strategies could be difficult to consider at these preliminary stages. Until recently, introducing energy simulation tools at the design stage has been difficult and perhaps next to impossible at a pre-design or programming stage. However, analysis of this sort is essential to ‘green building rating’ or performance assessment schemes such as LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environment Assessment Method). This paper discusses the implementation of a particular tool, ENERGY-10, where ‘basecase’ building defaults are compared to a low-energy case which has applied multiple energy-efficient strategies automatically. An annual hour-by-hour simulation provides a daylighting calculation with a subsequent thermal evaluation. Calculation results provide energy consumption, peak load equipment sizing, a RANK feature of the energy-efficient strategies, reporting of CO2, SO2 and NOx reduction, optimum glazing type as well as excellent graphic output. Consideration is given as to the approach of how such information can be introduced into the building project brief enforcing a low-energy
performance target.

Professional education and training for early career players in the Australian Football League: footy first, second and third

In this presentation we discuss some of the findings of a research project funded by the Australian Football League (AFL) titled: Getting the Balance Right: Professionalism, Performance, Prudentialism and Playstations in the Life of AFL Footballers. The research explored the following issues: the emergence and evolution of a ‘professional identity’ for AFL footballers – an identity that has many facets including the emerging ideas that a professional leads a balanced life, and has a prudent orientation to the future, to life after football. This ‘professional identity’ isn’t natural, and must be developed through a range of ‘professional development’ activities (a common link to all other ‘professions’). In the AFL at this time professional development has a focus on engaging players in a variety of education and training activities – TAFE & University courses, and workshops and seminars that the industry has put in place to educate players about issues that the industry sees as important.

The presentation will focus on our research with players we classified as Early Career players. For many of these 17 to 21 year old young men the later years of secondary schooling were compromised in their pursuit of an AFL career, and their subsequent drafting is followed by intense efforts to physically prepare them for football. In this context our research indicates that many Early Career players put football first, second and third – education and training, and industry expectations that they participate in this sort of professional development come further down their list of priorities.

High-intensity resistance training improves glycemic control in older patients with type 2 diabetes

OBJECTIVE -- To examine the effect of high-intensity progressive resistance training combined with moderate weight loss on glycemic control and body composition in older patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS -- Sedentary, overweight men and women with type 2 diabetes, aged 60-80 years (n = 36), were randomized to high-intensity progressive resistance training plus moderate weight loss (RT & WL group) or moderate weight loss plus a control program (WL group). Clinical and laboratory measurements were assessed at 0, 3, and 6 months.

RESULTS -- HbA._1c fell significantly more in RT & WL than WL at 3 months (0.6 ± or -] 0.7 vs. 0.07 ± 0.8%, P < 0.05) and 6 months (1.2 ±1.0 vs. 0.4 ±0.8, P < 0.05). Similar reductions in body weight (RT & WL 2.5 ±2.9 vs. WL 3.1±2.1 kg) and fat mass (RT & WL 2.4 ± 2.7 vs. WL 2.7±2.5 kg) were observed after 6 months. In contrast, lean body mass (LBM) increased in the RT & WL group (0.5 ±1.1 kg) and decreased in the WL group (0.4±1.0) after 6 months (P < 0.05). There were no between-group differences for fasting glucose, insulin, serum lipids and lipoproteins, or resting blood pressure.

CONCLUSIONS -- High-intensity progressive resistance training, in combination with moderate weight loss, was effective in improving glycemic control in older patients with type 2 diabetes. Additional benefits of improved muscular strength and LBM identify high-intensity resistance training as a feasible and effective component in the management program for older patients with type 2 diabetes.

Physical activity and television viewing in relation to risk and undiagnosed abnormal glucose metabolism in adults

OBJECTIVE--The goal of this study was to assess the associations of physical activity time and television (TV) time with risk of "undiagnosed" abnormal glucose metabolism in Australian adults.

RESEARCH DESIGN AND METHODS--This population-based cross-sectional study using a stratified cluster design involving 42 randomly selected Census Collector Districts across Australia included 8,299 adults aged 25 years or older who were free from new type 2 diabetes and self-reported ischemic disease and did not take lipid lowering or antihypertensive drugs. Abnormal glucose metabolism (impaired fasting glycetnia [IFG], impaired glucose tolerance [IGT], or new type 2 diabetes) was based on an oral glucose tolerance test Self reported physical activity time and TV time (previous week) were assessed using interviewer administered questionnaires.

RESULTS--Alter adjustment for known confounders and TV time, the odds ratio (OR) of having abnormal glucose metabolism was 0.62 (95% CI 0.41-0.96) in men and 0.71 (0.501.00) in women for those engaged in physical activity [greater than or equal to] 2.5 h/week compared with those who were sedentary (0 h/week). The ORs of having abnormal glucose metabolism were 1.16 (0.791.70) in men and 1.49 (1.12-1.99) in women who watched TV > 14 h/week compared with those who watched [less than or equal to] 7.0 h/week. Higher TV viewing (> 14 h/week) was also associated with an increased risk of new type 2 diabetes in men and women and IGT in women compared with those watching < 14 h/week. Total physical activity of [greater than or equal to] 2.5 h/week was associated with a reduced risk of IFG, IGT, and new type 2 diabetes in both sexes: however, only the association with IGT in women was statistically significant.

CONCLUSIONS--These findings suggest a protective effect of physical activity and a deleterious effect of TV time on the risk of abnormal glucose metabolism in adults. Population strategies to reduce risk of abnormal glucose metabolism should focus on reducing sedentary behaviors such as TV time, as well as increasing physical activity.

Australian adolescents' sun protection behavior : who are we kidding?

Purpose
To examine the influence of tan preference and skin type on sun protection behaviors of Australian adolescents.

Methods
The Australian Secondary School Alcohol and Drug Questionnaires were conducted in 1993, 1996, 1999 and 2002 among randomly selected students aged 12–-17. Schools were randomly selected from each education sector in each state. The self-administered questionnaire contained questions about tan preferences, skin type and usual SunSmart behavior (use of sunscreen, hats and covering clothing).

Results
The routine use of SunSmart behavior was low in all survey years. There was a significant decrease over time in the proportion of students who practiced SunSmart behavior, with prevalence rates lower in 2002 than in any other survey year (males: p < 0.01 and females: p < 0.01). As desire for a tan increased, routine practice of SunSmart behaviors decreased. Across the four survey periods, male (p < 0.01) and female (p < 0.01) students who preferred no tan were significantly more likely to practice SunSmart behavior than students who preferred any sort of tan. Across the four survey years, male (p < 0.01) and female (p < 0.01) students with skin that ‘just burns’ were most likely to routinely practice SunSmart behavior.

Conclusions
Sun protection practices among adolescents have continued to decline significantly over time. Future educational programs require an innovative approach to modify adolescent behaviors in relation to sun exposure and sun protection.

Simulation to practice: developing nursing skills in mental health: an Australian perspective

A variety of developments in nursing education in Australia including some innovative and exciting models, educational enterprises between education and industry, and evidence of developing strengths in research and professional alliances on a national level have been discussed recently. This paper presents Simulation to Practice as an example of an educational program that can maximise skill mastery for nurses in mental health fields as practised by Deakin University in Victoria, Australia. The program is multimodal and is under-pinned by a problem-solving approach and has an online presentation. The extension of nursing skills through this approach encourages nurses to take theoretical skills to practice during these scenarios which help student nurses to gain experience through simulated real life characters. These sessions, while challenging at the time, were highly valued by students and seen as a beneficial part of their learning as a beginning nurse and often instrumental in moving comprehensively trained students into mental health careers.

Stigmatization of patients with AIDS : understanding the interrelationships between Thai nurses' attitudes towards HIV/AIDS, drug use and commercial sex

There is currently a scarcity of research on the nature of HIV/AIDS stigma within the Thai health context. This is problematic given the negative role of stigma in hindering the provision of patient care and treatment. This study used a mixed-method approach to investigate the interrelationships between the stigma of HIV/AIDS and the stigmas relating to its various modes of disease transmission including injection drug use (IDU). Twenty interviews were conducted with trainees and qualified nurses from a Bangkok college. Participants were presented with vignettes describing a hypothetical person varying in disease diagnoses (AIDS, leukemia, no disease) and co-characteristics (IDU,  commercial sex (CS), blood transfusion, no co-characteristic). Using a Q-sort task, participants arranged the vignettes along a bipolar scale according to their willingness to interact with the persons, and were asked to explain their decisions. Univariate and multivariate regression analyses showed that IDU, AIDS, and CS were all individually stigmatizing. Strong interactions were found between the stigmas of HIV/AIDS, IDU, and CS. Interview data also showed clear biases toward patients according to their IDU and CS habits. The findings  suggest that addressing these co-stigmas could be vital to the success of efforts aimed at reducing the disease stigma of HIV/AIDS.
