HealthMap: a cluster randomised trial of interactive health plans and self-management support to prevent coronary heart disease in people with HIV

BACKGROUND: The leading causes of morbidity and mortality for people in high-income countries living with HIV are now non-AIDS malignancies, cardiovascular disease and other non-communicable diseases associated with ageing. This protocol describes the trial of HealthMap, a model of care for people with HIV (PWHIV) that includes use of an interactive shared health record and self-management support. The aims of the HealthMap trial are to evaluate engagement of PWHIV and healthcare providers with the model, and its effectiveness for reducing coronary heart disease risk, enhancing self-management, and improving mental health and quality of life of PWHIV.

METHODS/DESIGN: The study is a two-arm cluster randomised trial involving HIV clinical sites in several states in Australia. Doctors will be randomised to the HealthMap model (immediate arm) or to proceed with usual care (deferred arm). People with HIV whose doctors are randomised to the immediate arm receive 1) new opportunities to discuss their health status and goals with their HIV doctor using a HealthMap shared health record; 2) access to their own health record from home; 3) access to health coaching delivered by telephone and online; and 4) access to a peer moderated online group chat programme. Data will be collected from participating PWHIV (n = 710) at baseline, 6 months, and 12 months and from participating doctors (n = 60) at baseline and 12 months. The control arm will be offered the HealthMap intervention at the end of the trial. The primary study outcomes, measured at 12 months, are 1) 10-year risk of non-fatal acute myocardial infarction or coronary heart disease death as estimated by a Framingham Heart Study risk equation; and 2) Positive and Active Engagement in Life Scale from the Health Education Impact Questionnaire (heiQ).

DISCUSSION: The study will determine the viability and utility of a novel technology-supported model of care for maintaining the health and wellbeing of people with HIV. If shown to be effective, the HealthMap model may provide a generalisable, scalable and sustainable system for supporting the care needs of people with HIV, addressing issues of equity of access.

A study on energy and environmental management techniques used in petroleum process industries

Petroleum process industries are one of the most energy and emission intensive sectors throughout the world.There are natural gas processing plant, crude oils and condensate fractionation plant, liquefied natural gas plantand liquefied petroleum gas plant etc. creates environmental pollution by processing and handling of petroleumproducts. The study critically reviewed and discussed the energy and environmental management includingpollution control of petroleum process industries of Bangladesh. They produce both gaseous (process gas, wastegas etc.) and liquid (produced water, waste oil and grease etc.) pollutants. The study found that the liquid pollutantlike waste water is more hazardous and its treatment process is highly complicated due to its higher salinity, morecorrosivity and grease contain characteristics. As part of energy management, the rational use of energy and energyflow diagram of the petroleum industry is presented. Finally, a time frame measures which can be implemented inorder to save energy is outlined. The study concluded that the rational use of energy and proper environmentalmanagement are essential for achieving energy and environmental sustainability of process industries.

Sisyphus and self-management : the chronic condition self-management paradox

Chronic condition self-management is promoted internationally as not only a possible solution to the health problems of our increasingly chronically ill and ageing population, but as part of a new wave of consumer-led and volunteer-managed health care initiatives. Consumers are now indicating that they want to be more involved in the management of their lives and their health care options, while, especially in rural and smaller communities in Australia, a shortage of clinicians means that health care is rapidly changing. This emphasis on self-management raises crucial questions about where consumer action and control in health care should end and where clinical and medical intervention might begin. Hence, as in the case of Sisyphus and his rock, the self-management process is a difficult and demanding one that poses major challenges and loads for health system reformers and represents a struggle in which new difficulties are constantly emerging. This paper examines some implications of new self-management approaches to chronic illness from an ideological perspective and highlights key elements that underpin the effort to promote health-related lifestyle change. While peer-led self-management programs may assist certain individuals to live engaged and meaningful lives, the essential social and economic determinants of health and wellbeing mean that these programs are not the answer to our urgent need for major reform in the health care arena. Rather, self-management, from an ideological perspective, represents a minor adjustment to the fabric of our health system.

Control and charge management of a grid-connected photovoltaic system with plug-in hybrid vehicle as energy storage

This paper presents the control and charge management strategy of a photovoltaic system (PV) with plug-in hybrid electric vehicle (PHEV) as energy storage. The hybrid energy storage system (HESS) of PHEV consists of battery and supercapacitor. A simulation model for the PV system with PHEV energy storage has been developed using Matlab/SimpowerSystems. The system consists of PV arrays, SEPIC dc-dc converter with maximum power point tracking (MPPT), hybrid battery-supercapacitor energy storage with bidirectional dc-dc converter and inverter for grid connection. A charge management algorithm for the hybrid energy storage system is proposed to control the power flows among the PV system, energy storage and the grid. Results show that the proposed power management algorithm can control the power flows in an efficient manner.

Alcohol advertising in sport and non-sport TV in Australia, during children's viewing times

Estimate the amount of alcohol advertising in sport vs. non-sport programming in Australian free-to-air TV and identify children's viewing audience composition at different times of the day. Alcohol advertising and TV viewing audience data were purchased for free-to-air sport and non-sport TV in Australia for 2012. We counted alcohol advertisements in sport and non-sport TV in daytime (6 am-8.29 pm) and evening periods (8.30 pm-11.59 pm) and estimated viewing audiences for children and young adults (0-4 years, 5-13 years, 14-17 years, 18-29 years). During the daytime, most of the alcohol advertising (87%) was on sport TV. In the evening, most alcohol advertising (86%) was in non-sport TV. There was little difference in the mean number of children (0-17 years) viewing TV in the evening (N = 273,989), compared with the daytime (N = 235,233). In programs containing alcohol advertising, sport TV had a greater mean number of alcohol adverts per hour (mean 1.74, SD = 1.1) than non-sport TV (mean 1.35, SD = .94). Alcohol advertising during the daytime, when large numbers of children are watching TV, is predominantly in free-to-air sport TV. By permitting day-time advertising in sport programs and in any programs from 8.30 pm when many children are still watching TV, current regulations are not protecting children from exposure to alcohol advertising.

Ocean governance and risk management

The high seas have always engendered a range of emotions and reactions from humans. Curiosity, fear, even terror, of this great expanse of ocean which cover 70 % of Earth the blue planet. Yet the sheer size of the oceans and the difficulty of transporting across them meant the high seas were largely ignored by the vast majority of humans for centuries. Humans were largely confined to land with the only interest in the seas being as trade routes and the defence of the land. In fact all the way up to the last quarter of the twentieth century a nations territorial sea extended only three nautical miles off shore the distance that a cannon ball could be fired.

This almost casual relationship to the oceans changed dramatically in the 1960s and 1970s as technology played an ever icnreasing role in the exploitation of the natural resources of the seas. Fishing was made far easier by being able to use sophisticated sonar systems to detect the fish and by advanced nets and vessels. But it was probably the technological ability to first find and then extract oil and gas off shore on continental shelfs, and at increasing depths, which stimulated interest in exploiting marine resources. Dreams of other deep sea mineral resources (e.g. manganese nodules) simply fuelled interest in the oceans, not to mentino some of the pharmaceuticals that were being discovered.

Tertiary architecture and construction management students' academic performance: role of demographic variables

This study presents an account of how different demographic variables affect students’ academic performance. The studied sample comprises a cohort of 133 Architecture and Construction Management (ACM) students in a third-year unit allocated to construction methodology and structural knowledge required for high-rise construction. Data is collected for these students studying at the School of Architecture and Built Environment at Deakin University (A+B). Outcomes of group and individual task (exam) are analysed deploying statistical methods. The findings show no significant difference between students coming to university from Year-12-to-and those that come from the vocational education sector. Furthermore, the findings indicate significant discrepancy in terms of performance amongst the students enrolled in construction management course with double-degree and architecture students. Additionally, the study reveals that female students outperform male students in individual tasks. The findings could be applicable to redesigning assessments as well as planning of prerequisite units in the studied curricula.

Reviewing the hedge funds literature II:hedge funds' returns and risk management characteristics

This paper summarizes the literature on hedge funds (HFs) developed over the last two decades, particularly that which relates to risk management characteristics (a companion piece investigates the managerial characteristics of HFs). It discusses the successes and the shortfalls to date in developing more sophisticated risk management frameworks and tools to measure and monitor HF risks, and the empirical evidence on the role of the HFs and their investment behaviour and risk management practices on the stability of the financial system. It also classifies the HF literature considering the most recent contributions and, particularly, the regulatory developments after the 2007 financial crisis.

Dynamics and diversity of Escherichia coli in animals and system management of the manure on a commercial farrow-to-finish pig farm

The objective of this study was to determine the dynamics and diversity of Escherichia coli populations in animal and environmental lines of a commercial farrow-to-finish pig farm in Spain along a full production cycle (July 2008 to July 2009), with special attention to antimicrobial resistance and the presence of integrons. In the animal line, a total of 256 isolates were collected from pregnant sows (10 samples and 20 isolates), 1-week-old piglets (20 samples and 40 isolates), unweaned piglets (20 samples and 38 isolates), growers (20 samples and 40 isolates), and the finishers' floor pen (6 samples and 118 isolates); from the underfloor pits and farm slurry tank environmental lines, 100 and 119 isolates, respectively, were collected. Our results showed that E. coli populations in the pig fecal microbiota and in the farm environment are highly dynamic and show high levels of diversity. These issues have been proven through DNA-based typing data (repetitive extragenic palindromic PCR [REP-PCR]) and phenotypic typing data (antimicrobial resistance profile comprising 19 antimicrobials). Clustering of the sampling groups based on their REP-PCR typing results showed that the spatial features (the line) had a stronger weight than the temporal features (sampling week) for the clustering of E. coli populations; this weight was less significant when clustering was performed based on resistotypes. Among animals, finishers harbored an E. coli population different from those of the remaining animal populations studied, considering REP-PCR fingerprints and resistotypes. This population, the most important from a public health perspective, demonstrated the lowest levels of antimicrobial resistance and integron presence.

Socio-economic status, growth, physical activity and fitness: the Madeira growth study

Within a country social conditions change over time and these conditions vary from country to country. The associations between these conditions, somatic growth, physical activity and fitness reflect these changes. Aim: The study documented variation in somatic growth, physical activity and fitness associated with socio-economic status (SES). Subjects and methods: The study involved 507 subjects (256 boys and 251 girls) from the Madeira Growth Study, a mixed longitudinal study of five cohorts (8, 10, 12, 14 and 16 years of age) followed at yearly intervals over 3 years (1996–1998). A total of 1493 observations were made. Anthropometric measurements included lengths, body mass, skeletal breadths, girths and skinfolds. Physical activity and SES were collected via questionnaire and interview. Physical fitness was assessed using the Eurofit test battery. Variation in somatic growth, physical activity and physical fitness by SES (high, average and low) was tested with analysis of variance. Results: Significant differences between SES groups were observed for height, body mass and skinfolds. Boys and girls from high SES groups were taller, heavier and fatter (subscapular and triceps skinfolds) than their peers from average and low SES groups. At some age intervals, the high SES group had larger skeletal breadths (girls) and girths (boys and girls) than low SES. Small SES differences were observed for physical activity (sport and leisure-time indices). SES was significantly associated with physical fitness. At some age levels, boys from the low SES group performed better for muscular and aerobic endurance whereas girls from the high SES group performed better for power. Conclusion: Considerable variation in somatic growth and physical fitness in association with SES has been demonstrated, but little association was found for physical activity.

Human and social capital and environmental management in small firms: a developing country perspective

We examine the important roles of two forms of capital—human andsocial—in the accumulation of critical resources that enable firms to adopt soundenvironmental management practices which contribute to better firm performance.Drawing on human and social capital theories and the resource-based view of the firm,we tested this proposition using data from a survey of 141 small manufacturing firmsdrawn from a survey of business enterprises in a metropolitan city in the southernregion of the Philippines. The results of our analysis using structural equationmodelling-partial least square approach show that both human capital such as age,experience and education of managers of the firm and social capital such as externalmanagerial ties and networks have significant and positive contribution to the environmentalmanagement resources of firms although the effects vary in magnitude. Theaccumulation of environmental management resources not only is positively linked tothe adoption by firms of pro-environment practices but also fully mediates the effects ofthe two types of capital on the adoption of such practices. Pro-environment practicesare positively linked to better performance outcomes. The findings underscore the needto account for the intangible and more tacit forms of capital such as managerial talent,knowledge, skills and social ties and networks in the wider debate on how smallmanufacturing firms in developing countries can address the pressing need to integrateenvironmental sustainability in business.

Family control, board independence and earnings management : evidence based on Hong Kong firms

In this study, we document that independent corporate boards of Hong Kong firms provide effective monitoring of earnings management, which suggests that despite differences in institutional environments, corporate board independence is important to ensure high-quality financial reporting. The findings also show that the monitoring effectiveness of corporate boards is moderated in family-controlled firms, either through ownership concentration or the presence of family members on corporate boards. The results based on firms reporting small earnings increases provide additional support for our finding that the monitoring effectiveness of independent corporate boards is moderated in family-controlled firms.

Investor legal protection and earnings management : a study of Chinese H-shares and Hong Kong shares

Under the unique "one country, two systems" arrangement, the more stringent investor protection rules in Hong Kong are not enforceable in firms that are incorporated in China but listed on the Hong Kong stock exchange (H-shares). As such, H-shares and other local Hong Kong firms are subject to different investor protection regimes in the same stock market. We find that H-shares are associated with higher earnings management than local Hong Kong firms after controlling for disparity in economic development, types of controlling shareholders and other factors. More importantly, this relationship is weaker after China implemented the Securities Law in 1999. The results are robust after considering the dual-listing status of H-shares and board characteristics. These results provide direct evidence showing the effect of investor legal protection on financial reporting quality.

The Australia-United States alliance and the management of elite opinion

This thesis firstly demonstrates that support for the current Australia-United States alliance at the elite level primarily derives from the desire to sustain western control over regional and international affairs and extend Australia’s influence abroad. Secondly, it demonstrates the role of the Australian American Leadership Dialogue in sustaining alliance orthodoxy.
