Mobile solutions for front-line health workers in developing countries

We introduce an architecture for low-cost mobile Health (mHealth) applications that run on health-workers’ existing devices. Moreover, we envision extending the phone’s capabilities with an external to attach “sensor” modules, such as pulse oximeter, ECG and phonocardiogram. Our design principles are frugality and simplicity. We propose a comprehensive solution to aid health-workers in their daily tasks, at a low-cost and high penetration rate.

How precarious employment affects health and safety at work : the case of temporary agency workers

International studies indicate temporary agency workers are more likely to be injured at work than other types of employees. However explanations for this have been less forthcoming. This paper seeks to begin filling this gap. A study was undertaken in Victoria, Australia, of occupational health and safety (OHS) amongst temporary agency workers drawing upon workers' compensation claim files for injured agency and directly hired workers from 1995-2001, and focus groups of temporary agency workers conducted in 2003. In analyzing the results, use was made of risk factors identified in a model that has been developed to explain how precarious employment affects OHS--the pressure, disorganization and regulatory failure (PDR) model (Quinlan and Bohle, 2004, 2009). Drawing principally on qualitative data, the paper finds that whilst agency workers share common risk factors with other forms of precarious workers, unique characteristics associated with the triangular nature of agency employment heighten their vulnerability further.

Interacting with adults with congenital deafblindness : the experiences of disability support workers

Background This study aimed to gain greater insight into the perspectives of staff on their interactions with adults with congenital deafblindness in light of the research literature reporting these interactions to be lacking in quality and quantity.

Method Data from interviews with 8 disability support workers were analysed using the approach described by Charmaz (2006).

Results Three key themes emerged from the interview data, which support and elaborate on fi ndings of previous studies. These were (1) the construction of client happiness, (2) the rationalisation of client disengagement, and (3) imperatives of the staff role. These fi ndings elucidate the reasons for staff behaviour in their interactions with adults with congenital deafblindness.

Conclusion The fi ndings suggest the need for staff policy and procedural documents to be explicit about the importance of social interaction between staff and clients.

Copper levels in buccal cells of vineyard workers engaged in various activities

Objectives: Copper-based compounds have been used as agricultural fungicides for many years. Their use in Australia is escalating with increase in the scale of planting and associated pest problems. The objective of this study was to identify viticulture activities associated with high exposure to foliage sprays. It would be determined if occupational exposure of vineyard workers to copper-based sprays was associated with raised body copper levels through analysis of saliva and buccal cells.

Methods: The activities of six vineyard workers from four vineyards in the Yarra Valley Victoria, Australia, were monitored over a period of 2 years. During this period, workers carried out seasonal activities, including fungicide spraying, canopy management, and tractor operation. Saliva and buccal cells from workers were collected and analysed for copper levels that were then correlated with the different types of vineyard activity.

Results: The buccal cells of vineyard workers exposed to copper through seasonal activities including fungicide spraying, canopy management, and tractor operation contained copper levels of 0.87, 1.24, and 0.95 ng Cu per 106 cells, respectively. This was up to 10-fold higher than the copper levels in buccal cells from the control subjects (0.1 ng Cu per 106). Copper levels in buccal cells from workers participating in other viticulture activities such as shoot thinning, bunch counting, and disbudding were not significantly different from those of control subjects. The levels of copper in saliva samples of both workers undertaking any vineyard activity and control subjects were below the level of detection.

Conclusions: Seasonal activities undertaken in vineyards that involved direct contact with copper, in particular canopy management, fungicidal spraying, and tractor operation were associated with high copper levels in buccal cells of workers. This indicates that copper derived from copper-based fungicidal compounds is accumulated within body cells. The lack of detectable copper levels in saliva suggests that the route of transport of copper into buccal cells is not through saliva. The results indicate potential adverse health risks associated with use of copper fungicide. Recommendations are made in relation to the precautions that should be taken in relation to use of copper sprays and to validate buccal cells as an indicator of body copper status.

Physical activity initiatives for male factory workers : gatekeepers' perceptions of potential motivators and barriers

Objective: Worksites have been argued to be a key setting for physical activity promotion, particularly for lower-paid, less-skilled workers. These occupational groups are at increased risk of cardiovascular disease. There is no strong evidence in support of the efficacy of worksite fitness and physical activity interventions. This study assessed potential motivators and barriers to worksite physical activity initiatives for less-skilled workers.

Method: We conducted telephone interviews with 13 Victorian WorkCover insurance providers and 30 manufacturing industry worksite managers. The manufacturing industry was selected as it contains a substantial portion of workers from this high-risk occupational group.

Results: Most insurers incorporated physical activity elements into injury-prevention programs. Few worksite managers reported programs to encourage workers to be more active; they identified reduced premiums and lower-cost programs through insurers as possible motivators. Both groups identified workers' reluctance to participate in physical activity, lack of awareness of potential benefits and program cost as major barriers for worksite physical activity. Other barriers included potential adverse effects on productivity and increased injury risk.

Conclusions: Broader occupational health and safety policies and joint initiatives between insurers and worksite managers may have the potential to provide more opportunities for workers to be more active. However, the barriers identified outweighed the perceived benefits.

Implications: Without structural and regulatory changes or new incentives, the adoption of physical activity initiatives in Australian manufacturing-industry workplaces is unlikely.

Physical activity promotion for male factory workers : a realistic option?

Issue addressed: Worksites are a promising setting for health promotion initiatives. While there is an accumulated body of evidence indicating favourable health and cost outcomes, there have been difficulties identified in recruiting and influencing blue- collar workers. This descriptive study aimed to identify specific opportunities and barriers which may impact upon physical activity options at work for male blue-collar factory workers.

Methods: Fifteen manager interviews and worksite observations, and eight employee group discussions were conducted in manufacturing industry worksites.

Results: Several key barriers emerged which limit opportunities for blue-collar employees to participate in physical activity at work: time constraints; limited facilities; and lack of interest from management to facilitate physical activity due to limited resources and concerns about safety issues. Potential opportunities included the presence of change rooms, showers, outdoor areas suitable for physical activity, nearby parks and local fitness facilities, and occupational health and safety committees.

Conclusions: Increasing opportunities for workers to be active at work did not emerge as a priority of managers who may need to be convinced that allocating time and resources to physical activity is a wise investment and that workers need an environment that both supports and encourages participation in physical activity. The role of physical activity in relation to injury prevention and potential reductions in Workcover premiums is worthy of further investigation.

So what? While worksite physical activity promotion is a national health objective, there are numerous actual and perceived barriers to initiatives directed at factory workers. Rather than offering specific programs, it may be more productive to address work practices and environmental and regulatory barriers through established occupational health and safety channels. Information and education strategies to change the attitudes and beliefs of management and workers about these issues, as well as about the health benefits of physical activity, may also be helpful.

Uncertainty quantification for wind farm power generation

Accurate forecasting of wind farm power generation is essential for successful operation and management of wind farms and to minimize risks associated with their integration into energy systems. However, due to the inherent wind intermittency, wind power forecasts are highly prone to error and often far from being perfect. The purpose of this paper is to develop statistical methods for quantifying uncertainties associated with wind power generation forecasts. Prediction intervals (PIs) with a prescribed confidence level are constructed using the delta and bootstrap methods for neural network forecasts. The moving block bootstrap method is applied to preserve the correlation structure in wind power observations. The effectiveness and efficiency of these two methods for uncertainty quantification is examined using two month datasets taken from a wind farm in Australia. It is demonstrated that while all constructed PIs are theoretically valid, bootstrap PIs are more informative than delta PIs, and are therefore more useful for decision-making.

Development of a retention model for child protection workers

This thesis addressed the critical issue of retention in the child protection workforce. Key predictors of a workers 'intention to stay' or the 'likelihood of staying' were lifestyle factors and whether a worker had contemplated leaving the organisation. The degree of satisfaction was not in itself predictive of either intentions to stay or the actual 'likelihood of staying'.

Variation in the whiteness and brightness of white Australian cashmere associated with farm of origin and fibre attributes

While white cashmere is preferred by processors, its whiteness and brightness is affected by country of origin, amino acid composition, nutrition and cashmere production of goats. This work aimed to quantify the factors which affect the whiteness and brightness of 36 batches of processed Australian white cashmere sourced from nine different farms. The cashmere was tested for tristimulus values brightness (Y) and whiteness, as measured by yellowness (Y-Z). Linear models, relating Y and Y-Z were fitted to farm of origin and other objective measurements. Mean attributes (range) were: mean fibre diameter, 16.9 µm (13.9–20.4 μm); fibre curvature, 45°/mm (31–59°/mm); clean washing yield, 91.3% (79.5–97.3%); Y, 78.7 (74.7–82.2); Y-Z, 11.9 (10.3–13.6). Farm alone accounted for 72% of the variation in Y and 65% of the variation in Y-Z (P < 0.001). Once farm had been taken into account only fibre curvature (P = 0.003) was significant in predicting Y and only clean washing yield (P = 0.047) affected Y-Z. Neither the proportion of the fleece present as guard hair (clean cashmere yield) nor cashmere staple length was a significant determinant of Y or Y-Z. For each 10°/mm increase in fibre curvature Y increased 1.3 units. For each 10% increase in clean washing yield Y-Z declined 0.9 units. Variations in Y and Y-Z among farms were probably related to differences in geographic and climatic conditions and were significantly correlated to cashmere production. The effect of clean washing yield was probably related to a reduction in suint content.

Occupational health and safety among commercial sex workers

The concept of occupational health and safety (OHS) for commercial sex workers has rarely been investigated, perhaps because of the often informal nature of the workplace, the associated stigma, and the frequently illegal nature of the activity. We reviewed the literature on health, occupational risks, and safety among commercial sex workers. Cultural and local variations and commonalities were identified. Dimensions of OHS that emerged included legal and policing risks, risks associated with particular business settings such as streets and brothels, violence from clients, mental health risks and protective factors, alcohol and drug use, repetitive strain injuries, sexually transmissible infections, risks associated with particular classes of clients, issues associated with male and transgender commercial sex workers, and issues of risk reduction that in many cases are associated with lack of agency or control, stigma, and legal barriers. We further discuss the impact and potential of OHS interventions for commercial sex workers. The OHS of commercial sex workers covers a range of domains, some potentially modifiable by OHS programs and workplace safety interventions targeted at this population. We argue that commercial sex work should be considered as an occupation overdue for interventions to reduce workplace risks and enhance worker safety.
