Learning environment stimulation in the real world

This paper analyses some of the unique circumstances which confronted a member of the lecturing staff in the Real Estate Valuation course at the Gatton campus of the University of Queensland during the late 1990's. Due to the rapidly changing educational needs of valuation students, and requirements of the respective accreditation bodies, the location of the course in Gatton (a rural town) was recognised as being remote from a major city and although relocating the course was inevitable, this could not happen overnight. From Semester 1, 2000 after several years of planning, the degree course relocates to the Department of Geographical Sciences and Planning, St Lucia. This paper discusses some of the challenges confronted and the strategies employed to simulate a city environment in the bush whilst waiting for the move.

Hepatitis C virus treatment in the 'real-world': how well do 'real' patients respond?

Background: Published clinical trials of the treatment of HCV are largely multicentre prospective pharmaceutical trials. Patients in clinical trials tend to have more favorable outcomes than patients in the 'real-world', due to strict patient selection and differences in treatment conditions and available resources. Objectives: To assess the outcomes of Hepatitis C infected patients treated at the Barwon Health Liver Clinic with combination Pegylated interferon (PEG-IFN) and Ribavirin (RBV) therapy and to determine factors associated with a treatment response. Methods: Retrospective review of patients who received treatment for Hepatitis C at our institution's Liver Clinic from January 2001-September 2011. Patient demographics, comorbidities, treatment-related parameters and side effects were extracted from medical records and analyzed. Results: A total of 190 patients (120 male, 70 female) with a mean age of 42.8 years (range 20-68 years) commenced treatment. The most common genotype was genotype 3 (48.9%), followed by genotype 1 (42.6%). 150 of 190 patients (78.9%) completed treatment and had end of treatment data available. 107 of 182 patients, (58.8%) for whom sustained virologic response (SVR) rate data was available achieved an SVR. Overall response rates were; 46.9%, 68.8% and 62.4% in genotypes 1, 2 and 3 respectively. The response rate was significantly lower in 29 patients with documented cirrhosis (20.7%). Age, diabetes and alcohol abuse did not predict treatment response in our cohort. Side effects reported in 81.6% of patients included general malaise, hematological disturbance and psychiatric issues, and necessitated cessation of therapy in 16 patients (8.4%) and dose reduction in 26 patients (13.7%). Conclusions: Response rates to combination PEG-IFN and RBV therapy at our institution are comparable to other 'real-world' and pharmaceutical registration trials. Side effects of combination therapy were prominent but resulted in fewer discontinuations of therapy compared to pharmaceutical trials.

Challenges of diabetes prevention in the real world : results and lessons from the Melbourne diabetes prevention study

OBJECTIVE: To assess effectiveness and implementability of the public health programme Life! Taking action on diabetes in Australian people at risk of developing type 2 diabetes.

RESEARCH DESIGN AND METHODS: Melbourne Diabetes Prevention Study (MDPS) was a unique study assessing effectiveness of Life! that used a randomized controlled trial design. Intervention participants with AUSDRISK score ≥15 received 1 individual and 5 structured 90 min group sessions. Controls received usual care. Outcome measures were obtained for all participants at baseline and 12 months and, additionally, for intervention participants at 3 months. Per protocol set (PPS) and intention to treat (ITT) analyses were performed.

RESULTS: PPS analyses were considered more informative from our study. In PPS analyses, intervention participants significantly improved in weight (-1.13 kg, p=0.016), waist circumference (-1.35 cm, p=0.044), systolic (-5.2 mm Hg, p=0.028) and diastolic blood pressure (-3.2 mm Hg, p=0.030) compared with controls. Based on observed weight change, estimated risk of developing diabetes reduced by 9.6% in the intervention and increased by 3.3% in control participants. Absolute 5-year cardiovascular disease (CVD) risk reduced significantly for intervention participants by 0.97 percentage points from 9.35% (10.4% relative risk reduction). In control participants, the risk increased by 0.11 percentage points (1.3% relative risk increase). The net effect for the change in CVD risk was -1.08 percentage points of absolute risk (p=0.013).

CONCLUSIONS: MDPS effectively reduced the risk of diabetes and CVD, but the intervention effect on weight and waist reduction was modest due to the challenges in recruiting high-risk individuals and the abbreviated intervention.

Mixed method evaluation of a community-based physical activity program using the RE-AIM framework: practical application in a real-world setting

BACKGROUND: Communities are a pivotal setting in which to promote increases in child and adolescent physical activity behaviours. Interventions implemented in these settings require effective evaluation to facilitate translation of findings to wider settings. The aims of this paper are to i) present findings from a RE-AIM evaluation of a community-based physical activity program, and ii) review the methodological challenges faced when applying RE-AIM in practice.

METHODS: A single mixed-methods case study was conducted based on a concurrent triangulation design. Five sources of data were collected via interviews, questionnaires, archival records, documentation and field notes. Evidence was triangulated within RE-AIM to assess individual and organisational-level program outcomes.

RESULTS: Inconsistent availability of data and a lack of robust reporting challenged assessment of all five dimensions. Reach, Implementation and setting-level Adoption were less successful, Effectiveness and Maintenance at an individual and organisational level were moderately successful. Only community-level Adoption was highly successful, reflecting the key program goal to provide community-wide participation in sport and physical activity.

CONCLUSIONS: This research highlighted important methodological constraints associated with the use of RE-AIM in practice settings. Future evaluators wishing to use RE-AIM may benefit from a mixed-method triangulation approach to offset challenges with data availability and reliability.

The use of codes of ethics in the marketplace in corporate Australia : a longitudinal study

The stock market crash of 1987 was a defining moment in Australian corporate life. As a nation, we became acutely aware of the ‘moral bankruptcy’ that had come to permeate our corporate world. The focus on business ethics or the lack of it, in corporate Australia in the late 1980s, prompted this research.

The research for this paper that was first conducted in 1995 and replicated in 2001 focussed on the top 500 companies in Australia. These companies were surveyed on a raft of issues, one of which was their use of their codes of ethics in the marketplace. This paper examines the data sets from 1995 and 2001 and concludes that many of Australia’s largest enterprises have recognised the need for business ethics. As perceived by them, they can and do use their codes of ethics in a positive manner in the marketplace and attribute benefits to this interaction.

The use of codes of ethics in the corporate marketplace: the case of Australia and Sweden

Business ethics is a subject that recently has been thrust again into prominence in industrialised economies around the world, due to the revelations of the practices of some of the major corporations operating within the USA. In Australia, corporate collapses such as HIH and Onetel and in Sweden, the scandals with the top executives of Skandia and also Systembolaget have brought in to sharp focus that these practices are not confined to the USA. Since the early 1960s, codes of ethics have been in evidence in many organisations in the USA, whilst in Australia, as in Britain, the interest in codes of ethics was piqued by the stock market crash of 1987. In Sweden, however, this concept of the use of codes of ethics in the corporate sector had not been investigated prior to this study. This paper examines the use of codes of ethics in the marketplace by the top companies operating in corporate Australia and corporate Sweden. The outcome of this research shows that in both Australia and Sweden that large organisations indicate a substantial interest in codes of ethics and value the use of their codes in the marketplace. There are, however, differences in the ways that the companies in each country implement their codes of ethics in the marketplace and the benefits that they see as being derived from them.

Scandal, censorship and representation in the online world : an ethical conundrum

This research begins by examining the foundation issues of content censorship from a literary perspective and then proceeds in comparison to discuss the issues of online content appropriateness and whether the same censorship principles of literature are transitional to the online world. Currently, uncertainty exists in how to tackle this issue as there appears to be a lack of formal rules or suggested guidelines applied to the content appropriateness, management and availability of online material. Therefore, where does the onus of online content censorship exist in this medium? Or is it left to the ethical and moral standards of the material source/creator, online access provider or the cultural ethics of the wider community to adjudicate?

Security and ethical issues in the virtual world of Second Life

In recent times, Virtual Worlds such as Second Life have generated substantial publicity due to the participation of Fortune 500 companies, and other public and private organisations. As practitioners continue to discuss how organisations could derive business value from Virtual Worlds, new security and ethical issues in Virtual Worlds have emerged to challenge Virtual World users and stakeholders. This paper discusses privacy, intellectual property and a host of other security and ethical issues in Virtual Worlds. It contributes to practice and research by (i) providing insight into emerging security and ethical issues in Virtual Worlds, (ii) analysing the implication of these issues, within and beyond Virtual Worlds, and (iii) raising awareness on security and ethics among Virtual World users and stakeholders.

Beyond the analogon; the "transfer of the referent" : the relationship between the external world experienced through culturally generated perceptual models constructed in the human mind, and the transfer of these images, via visual language, onto referen

Within 20th. Century art, the concept of the ‘normative’ image, as an attribute of things, has been challenged. As a consequence, paintings must now picture the ‘real’ world in other ways, incorporating knowledge and meaning beyond the analogon. Such descriptive representations were revealed as paradigmatic, rather than incontrovertible fact. Dependent on pre-conceived notions of stereotypicality, these descriptive images relied on surface illumination. My thesis explores images of things in the world as culturally inspired and information based. I examine paintings and sculptures of other cultures, such as black African, and other historical periods such as the Medieval, which reveal metonymously the basis for variations in representations of the ‘real’ world. The new enhanced representations which Modern artists created in their work were denigrated as deviant from the absolute ‘normative’ or regarded as distortions for purely mannerist and stylistic reasons. Postmodern research has reassessed them as multiple or extended imagings in whose facture new knowledge and human responses can be incorporated. These new forms of representation can be regarded as theoretical constructs rather than stylised depictions of appearance. In this way referents are transferred through the mind onto objects and vistas in the real world to align with our developed view of the physical world and better our understanding of humanity’s symbiotic relationship with nature.

Welcome to the real world

The novel 'Welcome to the real world' and its exegesis 'Gaps in reality' explore the changing ideas of what it means to be a parent and the member of an extended family in Australia today. Through fiction and critical theory the thesis reflects on the evolving values within contemporary society.

Becoming at home in the natural world

This thesis links the environmental crisis with a contemporary sense of meaninglessness, which the philosopher Martin Heidegger interprets in terms of unrecognised ontological homelessness. Within his work it discerns a transitory and transformative pathway of thinking that reveals an enduring, thoughtful and holistic self-understanding and enables an authentically human response.
