Disentangling the layering of HIV/AIDS-related stigma

This thesis highlights the complexity of the inter-relationships between the disease stigma of HIV/AIDS and common modes of HIV transmission, such as injecting drug use, among health professionals in Asia. New ways of deconstructing disease-related stigma were explored. The findings pose challenges for the conventional approaches to HIV/AIDS stigma intervention.

A critical evaluation of the standardisation potential of business plan evaluation aids (BPEA) used in venture capital investment decision-making

The research objective was to perform a critical evaluation and comparison of four, representative Business Plan Evaluation Aids (BPEA) to facilitate constructive discussion of the proposition that greater standardisation of venture capital decision-making might be both desirable and possible.

The four BPEA were systematically compared using a structured, taxonomic process employing seven key criteria. The evidence of this investigation suggests a clear superiority for BPEAs, which are based on the known attributes of successful ventures and use actuarial modelling. Discussion centred on the importance of using BPEAs in a quest for greater consistency of venture capital investment decision-making.

Navigation of four-wheel-steering mobile robots using robust fault-tolerant sliding mode control

This paper addresses the leader-follower tracking problem of a four-wheel-steering robot subjected to nonlinear uncertainties. Two control laws have been developed, based on the adaptive sliding mode method and the adaptive input-output feedback linearization method. The proposed control schemes have been tested by means of simulations.

The 6-PACK programme to decrease fall-related injuries in acute hospitals: protocol for a cluster randomised controlled trial

Background and aims In-hospital fall-related injuries are a source of personal harm, preventable hospitalisation costs, and access block through increased length of stay. Despite increased fall prevention awareness and activity over the last decade, rates of reported fall-related fractures in hospitals appear not to have decreased. This cluster randomised controlled trial (RCT) aims to determine the efficacy of the 6-PACK programme for preventing fall-related injuries, and its generalisability to other acute hospitals.

Methods 24 acute medical and surgical wards from six to eight hospitals throughout Australia will be recruited for the study. Wards will be matched by type and fall-related injury rates, then randomly allocated to the 6-PACK intervention (12 wards) or usual care control group (12 wards). The 6-PACK programme includes a nine-item fall risk assessment and six nursing interventions: ‘falls alert’ sign; supervision of patients in the bathroom; ensuring patient’s walking aids are within reach; establishment of a toileting regime; use of a low-low bed; and use of bed/chair alarm. Intervention wards will be supported by a structured implementation strategy. The primary outcomes are fall and fall-related injury rates 12 months following 6-PACK implementation.

Discussion This study will involve approximately 16 000 patients, and as such is planned to be the largest hospital fall prevention RCT to be undertaken and the first to be powered for the important outcome of fall-related injuries. If effective, there is potential to implement the programme widely as part of daily patient care in acute hospital wards where fall-related injuries are a problem.

Contextual navigation in a multimedia journal

This work presents a framework for multimedia journaling,maintaining strong relationships between the document and embedded media. This enables media archives that are robust to changes in software environments, such as changes in web-sharing services, proprietary file formats and enables portability across operating system. We develop a journaling application using an existing multimedia framework, and show the power of the paradigm with specific case studies.

A unified formalism for landmark based representation of maps and navigation plans

We present a unified formalism for representing maps and using them for constructing plans of navigation for an autonomous agent. The foundation of this work lies in addressing key questions that an agent is confronted with when navigating. That is, besides the main task of how to reach the intended destination from the current position, the agent faces other questions like: where am I? what landmarks can I see? where is my destination relative to me and the landmarks I am seeing? Fundamental to this representation is the use of visual landmarks, which are used as pivotal points in the landscape being described. Further, in the representation of spatial information and navigation there are three different viewpoints: first, the localized representation from the viewpoint of a sighted, mobile agent; second, the static representation seen by the map-maker; and third, the view of an external agent giving directions on the basis of his own experience/knowledge. The major contribution of this map model and the associated navigation method lies in the framework which unifies these three different points of view. This unification enables the agent to make no distinction in terms of following implicit instructions contained in a map and the directions given by external agents.

Churches, mosques, and condoms : understanding successful HIV and AIDS interventions by faith-based organisations

There are an estimated 33 million people living with the Human Immunodeficiency Virus (HIV) worldwide. While national education campaigns have been successful in providing a broad platform of awareness of HIV and AIDS, within some countries faith-based organisations (FBOs) have assumed an important role in educating and supporting local communities to reduce HIV transmission. This article conceptualises the successful characteristics of a Christian organisation in West Papua and a Muslim organisation in Thailand. The ability of both these FBOs to engage successfully with their communities on issues of sexual practice provides important lessons for other FBOs seeking to reduce HIV transmission.

A multi-objective sensitivity approach to training providers' evaluation and quota allocation planning

The practice of solely relying on the human resources department in the selection process of external training providers has cast doubts and mistrust across other departments as to how trainers are sourced. There are no measurable criteria used by human resource personnel, since most decisions are based on intuitive experience and subjective market knowledge. The present problem focuses on outsourcing of private training programs that are partly government funded, which has been facing accountability challenges. Due to the unavailability of a scientific decision-making approach in this context, a 12-step algorithm is proposed and tested in a Japanese multinational company. The model allows the decision makers to revise their criteria expectations, in turn witnessing the change of the training providers' quota distribution. Finally, this multi-objective sensitivity analysis provides a forward-looking approach to training needs planning and aids decision makers in their sourcing strategy.

The politics of the pharmaceutical industry and access to medicines : world pharmacy and India

The Pharmaceutical Industry presents one of India’s most successful stories of economic expansion and improvements in public health. Indian firms have made access to quality medicines possible and affordable in many developing countries. Indian pharmaceuticals are also exported on a large scale to the United States and other highly regulated markets. A wave of mergers, acquisitions and tie-ups point to growing integration between Indian firms and global pharma multinationals.

The Politics of the Pharmaceutical Industry and Access to Medicines: World Pharmacy and India examines this important industry from different economic, social and political perspectives. Topics covered include the implications of TRIPS-compliant intellectual property rights, the role of flexibilities under TRIPS, the market regulation system, the role of Indian firms in exporting HIV/AIDS medications to Africa, the issue of free trade agreements, the power and reach of foreign pharmaceutical multinationals in India’s domestic market, and the sustainability of India as a major generics supplier.

Direct versus search engine traffic : an innovative approach to demand analysis in the property market

Purpose – The application of “Google” econometrics (Geco) has evolved rapidly in recent years and can be applied in various fields of research. Based on accepted theories in existing economic literature, this paper seeks to contribute to the innovative use of research on Google search query data to provide a new innovative to property research.

Design/methodology/approach – In this study, existing data from Google Insights for Search (GI4S) is extended into a new potential source of consumer sentiment data based on visits to a commonly-used UK online real-estate agent platform (Rightmove.co.uk). In order to contribute to knowledge about the use of Geco's black box, namely the unknown sampling population and the specific search queries influencing the variables, the GI4S series are compared to direct web navigation.

Findings – The main finding from this study is that GI4S data produce immediate real-time results with a high level of reliability in explaining the future volume of transactions and house prices in comparison to the direct website data. Furthermore, the results reveal that the number of visits to Rightmove.co.uk is driven by GI4S data and vice versa, and indeed without a contemporaneous relationship.

Originality/value – This study contributes to the new emerging and innovative field of research involving search engine data. It also contributes to the knowledge base about the increasing use of online consumer data in economic research in property markets.

An exploration of the impact of celebrity on the HIV/AIDS pandemic

The framework we present in this article separates into three generations the celebrity/personality involvement in the AIDS movement that has been steadily building momentum over the past 25 years. We analyze the celebrification of HIV/AIDS and the role of the media in the process. We contend the relationship between celebrity, the public and HIV/AIDS is multipurpose: celebrities maintain a positive public presence between projects while allowing themselves and their supporting fans to feel good about taking on and affecting a meaningful cause. Celebrities are vehicles and embodiments of concern that act as proxies for their various audiences. And this is their power–celebrities are embodiments of their audiences. The awareness that celebrities have brought to the HIV/AIDS epidemic has resulted in better treatment for victims and increased government support for medical research, and yet has also distracted the public’s attention from the scope of the epidemic. It is the third generation of celebrities who are refocusing efforts on worldwide prevention and a cure for HIV/AIDS.

How the concept of agency aids in teaching about sustainability

Sustainability education is becoming an integral part of education for all students.The paper revisits startling results from large scale international studies that show the dissonance between young people’s sustainability knowledge and the resistance of young people to put into practice. The reluctance to enact sustainability knowledge necessitates a review of current teaching practices as these raise important issues about current models of education and how sustainability is captured within education. Education about sustainability seeks to future proof our society through the teaching and learning of actions that ensure our collective long term future. For this reason teaching about sustainability incorporates a focus on social responsibility as well as individual responsibility. 

Oceanic long-distance navigation : do experienced migrants use the earth's magnetic field?

Albatrosses and sea turtles are known to perform extremely long-distance journeys between disparate feeding areas and breeding sites located on small, isolated, oceanic islands or at specific coastal sites. These oceanic journeys, performed mainly over or through apparently featureless mediums, indicate impressive navigational abilities, and the sensory mechanisms used are still largely unknown. This research used three different approaches to investigate whether bi-coordinate navigation based on magnetic field gradients is likely to explain the navigational performance of wandering albatrosses in the South Atlantic and Indian Oceans and of green turtles breeding on Ascension Island in the South Atlantic Ocean. The possibility that magnetic field parameters can potentially be used in a bi-coordinate magnetic map by wandering albatrosses in their foraging area was investigated by analysing satellite telemetry data published in the literature. The possibilities for using bi-coordinate magnetic navigation varied widely between different areas of the Southern Oceans, indicating that a common mechanism, based on a bi-coordinate geomagnetic map alone, was unlikely for navigation in these areas. In the second approach, satellite telemetry was used to investigate whether Ascension Island green turtles use magnetic information for navigation during migration from their breeding island to foraging areas in Brazilian coastal waters. Disturbing magnets were applied to the heads and carapaces of the turtles, but these appeared to have little effect on their ability to navigate. The only possible effect observed was that some of the turtles with magnets attached were heading for foraging areas slightly south of the control turtles along the Brazilian coast. In the third approach, breeding female green turtles were deliberately displaced in the waters around Ascension Island to investigate which cues these turtles might use to locate and return to the island; the results suggested that cues transported by wind might be involved in the final stages of navigation.
