Clinical usefulness and feasibility of using Reality Orientation with patients who have dementia in acute care settings

Reality Orientation (RO) was developed as a strategy to assist people with dementia to improve their orientation and everyday function. Although its efficacy has been extensively studied in long-term care facilities, its effectiveness has rarely been examined in acute care settings. The aim of this review was to examine the studies cited in systematic reviews of RO to determine the potential clinical usefulness and the feasibility of using RO in acute care settings. Based on this information, the authors make recommendations for future research in this area. The feasibility of implementing RO in acute care poses challenges because of the short time a patient is in hospital and their ability to participate given their acute medical condition. Although the efficacy and feasibility of using RO in acute care settings have not been sufficiently examined, its potential to improve care should not be ignored. A comprehensive and rigorous study is necessary to investigate the usefulness of RO in the acute care setting and to help establish clinical guidelines for dementia care in the context of acute care nursing.

The present and the future of digital TV in Australia

Australia adopted digital TV (DTV) on January 1, 2001 but due to slow adoption by end users, the deadline to discontinue the analog signal has so far been postponed twice. This paper examines the history and current status of DTV adoption in Australia with reference to theories of adoption and diffusion and the Justification Model of Technology and why end users
appear reluctant to adopt-in spite of affordable converters. End user opinions are examined on ‘why they do not adopt’ and ‘what may encourage them to adopt’, using public submissions to the 2005 parliamentary ‘Inquiry into the uptake of digital TV in Australia’. The paper advocates relevant media literacy programs to address the low public awareness of DTV and its benefits because its rejection may result in less affluent end users losing the chance to receive a range of convergent services in the future via the ubiquitous and affordable television.

School and anaemia prevention: current reality and opportunities - a Tanzanian case study

Iron deficiency anaemia is highly endemic in rural areas of Tanzania and in many developing countries. Its prevention among school children requires greater dissemination of knowledge of anaemia among children, teachers, parents and the general community. Associated improvements in the hygienic status of domestic and school environments are also often required. One-hundred-and-thirty-one anaemic children, 90 parents and 76 teachers were interviewed to ascertain their understanding of anaemia. Most children and parents had little knowledge of the symptoms, causes and prevention of anaemia. In addition to their iron-deficient diets, more than half of the children went to school without something to eat at breakfast and during school hours. However, parents and teachers were willing to work together to provide meals for the children. Poor sanitation in the children's homes and in schools was a little recognized factor which could pose a serious risk of anaemia. In addition, inadequate sanitation facilities and poor quality of physical environment prevailed both in the children's homes and in schools. The findings suggest the need for the establishment of a health-promoting schools network to provide a comprehensive framework for health promotion in schools as well as in homes in Tanzania and in other developing countries. Schools can be an ideal setting to positively influence a community's health status. Partnerships among teachers, parents and the wider community are required to identify, prioritize and ameliorate health problems.

Associations of TV viewing and physical activity with the metabolic syndrome in Australian adults

Aims/hypothesis We analysed a sample of Australian adults to determine the strength of associations of TV viewing and participation in physical activity with the metabolic syndrome.

Methods This population-based cross-sectional study included 6,241 adults aged ge35 years who were free from diagnosed diabetes mellitus and self-reported ischaemic disease and were not taking lipid-lowering or antihypertensive drugs. The metabolic syndrome was defined according to the 1999 World Health Organization criteria. Participants self-reported TV viewing time and physical activity time for the previous week.

Results The adjusted odds ratio of having the metabolic syndrome was 2.07 (95% CI 1.49–2.88) in women and 1.48 (95% CI 0.95–2.31) in men who watched TV for >14 h per week compared with those who watched le7.0 h per week. Compared with those who were less active (<2.5 h per week), the odds ratio for the metabolic syndrome was 0.72 (95% CI 0.58–0.90) in men and 0.53 (95% CI 0.38–0.74) in women who were active (ge2.5 h per week). Longer TV viewing (>14 h per week) was associated with an increased risk of insulin resistance, obesity and dyslipidaemia in both men and women. A total physical activity time of ge2.5 h per week was associated with a reduced prevalence of both insulin resistance and dyslipidaemia in both sexes and reduced prevalence of both obesity and hypertension in women.

Conclusions/interpretation Increased TV viewing time was associated with an increased prevalence of the metabolic syndrome, while physical activity was associated with a reduced prevalence. Population strategies addressing the metabolic syndrome should focus on reducing sedentary behaviours such as TV viewing, as well as increasing physical activity.

The nature of data: illusions of reality

The nature of data has changed as human technology has evolved. ‘Natural’ analogue data stimulate our senses, whilst machine produced data provides an intermediary for natural or artificial data to our senses. In the age of the cyborg (a machine with human attributes) and the bionic person (a human with machine attributes), it is possible for data totally alien from ‘natural reality’ to be fed directly to the brain so by-passing the senses. This is a new form of reality, which lends itself to manipulation of a kind never experienced before. The dreams of deceivers may yet be realised on a mass scale.

The reality of quality systems software : working for the machine, or smart people around the machine?

This case study-based research examines the outcomes of using quality system software (QSS) in terms of the support it provides to, and the constraints it imposes on, its users. The results indicate that QSS can help facilitate knowledge access and sharing, and to a lesser extent, facilitate communication. It can be an effective mechanism for initiating and managing changes to work processes. Although some writers have opined that information technology (IT) is another way of controlling workers, this was not evidenced in this study. Technical shortcomings did hamper performance of some tasks, and for some managers, extra work was involved.

The China threat : perceptions, myths and reality

"Since the end of the Cold War, one of the most significant debates in international relations has been the question of whether the rise of China as a major economic, political and military power will be a force for stability or instability in the international system and the East Asian region. Forceful arguments have been put forward on both sides."
"This book examines perceptions of the 'China Threat', and governments' policies in response to the perceived threat in a wide range of countries, including the United States, Russia, Europe, Japan, South Asia, South-East Asia and the Middle East, as well as the perceptions of the Chinese themselves. For each country current security concerns and policies, especially the policy of engagement, are examined in detail, and future prospects for relations with China are assessed. As the Bush administration in Washington increasingly focuses on China as a 'strategic competitor' and Sino-US-relations become increasingly tense, the 'China Threat' issue has come to dominate the security agenda in the Asia-Pacific region, and now poses the biggest foreign policy challenge of the twenty-first century."
