Workers’ compensation and mental health : examining the mental health impacts of involvement in the Victorian Work Cover system from the perspective of long-­term injured workers

The project aimed to explore long--term injured workers’ experiences and perceptions of their mental health as they progressed through the Victorian WorkCover process. The purpose of the project was to assist in understanding these factors in order to identify how workers might be better supported, and to identify changes that compensation authorities, employers and unions can make to reduce mental distress amongst injured workers. As a project based on workers’ accounts of their experiences, it aimed to provide a narrative basis for the development of supportive policy and practice to reduce mental distress amongst people who are clients of the WorkCover system. The project was a qualitative study based on fifteen in--depth interviews with people who had been injured at work and who had been off work for at least six months. The workers who took part in the study were recruited with the assistance of their trade unions, using an advertisement that was distributed via the unions’ regular communication channels. Workers were asked to tell their story of injury and recovery with a particular focus on how they felt and the factors that affected them, both positively and negatively. They were also asked what could or should be changed to support workers’ recovery and improve their experience of the WorkCover system. The workers who took part in the study came from a variety of industry sectors (education, textile and clothing manufacturing and meat industries) and different occupational categories (professional, trade/technical and manual). They included people whose primary injury was physical and those whose primary injury was psychosocial.

Primary prevention of latex related sensitisation and occupational asthma : a systematic review

Eight primary prevention intervention studies on natural rubber latex (NRL) published since 1990 were identified and reviewed. This is the largest evidence base of primary prevention studies for any occupational asthmagen. Review of this small and largely observational evidence base supports the following evidence statement: Substitution of powdered latex gloves with low protein powder‐free NRL gloves or latex‐free gloves greatly reduces NRL aeroallergens, NRL sensitisation, and NRL‐asthma in healthcare workers. Evidence in support of this statement is ranked SIGN level 2+, referring to well conducted case‐control or cohort studies with a low risk of confounding, bias, or chance and a moderate probability that the relationship is causal. Substitution of powdered latex gloves with low protein powder‐free NRL gloves or latex‐free gloves promises benefits to both workers' health and cost and human resource savings for employers. This message should be broadly disseminated beyond the hospital sector to include other healthcare settings (such as aged care facilities) as well as food service and other industries where latex gloves might be used.

Rapid discrimination and determination of polyunsaturated fatty acid composition in marine oils by FTIR Spectroscopy and Multivariate Data Analysis

A rapid analytical approach for discrimination and quantitative determination of polyunsaturated fatty acid (PUFA) contents, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in a range of oils extracted from marine resources has been developed by using attenuated total reflection Fourier transform infrared spectroscopy and multivariate data analysis. The spectral data were collected without any sample preparation; thus, no chemical preparation was involved, but data were rather processed directly using the developed spectral analysis platform, making it fast, very cost effective, and suitable for routine use in various biotechnological and food research and related industries. Unsupervised pattern recognition techniques, including principal component analysis and unsupervised hierarchical cluster analysis, discriminated the marine oils into groups by correlating similarities and differences in their fatty acid (FA) compositions that corresponded well to the FA profiles obtained from traditional lipid analysis based on gas chromatography (GC). Furthermore, quantitative determination of unsaturated fatty acids, PUFAs, EPA and DHA, by partial least square regression analysis through which calibration models were optimized specifically for each targeted FA, was performed in both known marine oils and totally independent unknown n - 3 oil samples obtained from an actual commercial product in order to provide prospective testing of the developed models towards actual applications. The resultant predicted FAs were achieved at a good accuracy compared to their reference GC values as evidenced through (1) low root mean square error of prediction, (2) good coefficient of determination close to 1 (i.e., R 2≥ 0.96), and (3) the residual predictive deviation values that indicated the predictive power at good and higher levels for all the target FAs. © 2014 Springer Science+Business Media New York.

Recent insights into microbial catalases: isolation, production and purification

Catalase, an oxidoreductase enzyme, works as a detoxification system inside living cells against reactive oxygen species formed as a by-product of different metabolic reactions. The enzyme is found in a wide range of aerobic and anaerobic organisms. Catalase has also been employed in various analytical and diagnostic methods in the form of biosensors and biomarkers in addition to its other applications in textile, paper, food and pharmaceutical industries. New applications for catalases are constantly emerging thanks to their high turnover rate, distinct evolutionary origin, relatively simple and well-defined reaction mechanisms. The following review provides comprehensive information on isolation, production and purification of catalases with different techniques from various microbial sources along with their types, structure, mechanism of action and applications.

Opportunities and challenges in developing a whole-of-government national food and nutrition policy: lessons from Australia's National Food Plan

OBJECTIVE: The present article tracks the development of the Australian National Food Plan as a 'whole of government' food policy that aimed to integrate elements of nutrition and sustainability alongside economic objectives. DESIGN: The article uses policy analysis to explore the processes of consultation and stakeholder involvement in the development of the National Food Plan, focusing on actors from the sectors of industry, civil society and government. Existing documentation and submissions to the Plan were used as data sources. Models of health policy analysis and policy streams were employed to analyse policy development processes. SETTING: Australia. SUBJECTS: Australian food policy stakeholders. RESULTS: The development of the Plan was influenced by powerful industry groups and stakeholder engagement by the lead ministry favoured the involvement of actors representing the food and agriculture industries. Public health nutrition and civil society relied on traditional methods of policy influence, and the public health nutrition movement failed to develop a unified cross-sector alliance, while the private sector engaged in different ways and presented a united front. The National Food Plan failed to deliver an integrated food policy for Australia. Nutrition and sustainability were effectively sidelined due to the focus on global food production and positioning Australia as a food 'superpower' that could take advantage of the anticipated 'dining boom' as incomes rose in the Asia-Pacific region. CONCLUSIONS: New forms of industry influence are emerging in the food policy arena and public health nutrition will need to adopt new approaches to influencing public policy.

A different kettle of fish : mental health strategies for Australian fishers, and farmers

Despite being typically represented and managed under the same policy umbrella, fishers face different challenges than do their farming counterparts. This paper unpacks the findings of research depicting poor levels of mental health and well-being among Australian commercial wild-catch fishers. The research is considered in the context of widespread acceptance that farmers tend to exhibit worse than average mental health outcomes due, at least in part, to the environmental uncertainties of climate change. In particular it is stressed that the insecurity of fishing concessions (quota and licenses), is a key driver of chronic livelihood insecurity, resulting in reports of stress, depression and suicide. A call is made for the separation of health research in the fishing and farming industries. Importantly, the role that tenure insecurity plays in the perpetuation of poor mental health among fishers should be acknowledged and addressed so that the fishing industry can maximize the strength of its human capital.

Recreational drug use within the employees of the mariculture and seafood industry in South Australia

A study of recreational drug use among workers in the Port Lincoln mariculture and seafood industries was conducted by self report questionnaire. High rates of cannabis and alcohol use were revealed during the shore based fish farming season. The occupational health and safety implications of these findings in one of Australia's most dangerous industries are significant. Further research could inform the development of industry specific harm minimisation policies.

Food-derived multifunctional bioactive proteins and peptides: applications and recent advances

Owing to their biological roles, multifunctional peptides constitute a new generation of biologically active molecules whose potential can be exploited in several industrial applications such as functional food, pharmaceutical, and cosmeceutical industries. With the required combination and balance of research and commercial operations, major corporations can effectively harness the diverse functionalities of these peptides for enhanced nutrition and the treatment and mitigation of ill health. However, further insightful research in vivo and clinical studies are needed to unravel the mechanism and fate of these peptides en route to the body systems. This is needed to firmly establish the therapeutic potency of these peptides.

Monodisperse aqueous microspheres encapsulating high concentration of l-ascorbic acid: insights of preparation and stability evaluation from straight-through microchannel emulsification

Stabilization of l-ascorbic acid (⌊-AA) is a challenging task for food and pharmaceutical industries. The study was conducted to prepare monodisperse aqueous microspheres containing enhanced concentrations of ⌊-AA by using microchannel emulsification (MCE). The asymmetric straight-through microchannel (MC) array used here constitutes 11 × 104 μm microslots connected to a 10 μm circular microholes. 5-30% (w/w) ⌊-AA was added to a Milli-Q water solution containing 2% (w/w) sodium alginate and 1% (w/w) magnesium sulfate, while the continuous phase constitutes 5% (w/w) tetraglycerol condensed ricinoleate in water-saturated decane. Monodisperse aqueous microspheres with average diameters (dav) of 18.7-20.7 μm and coefficients of variation (CVs) below 6% were successfully prepared via MCE regardless of the ⌊-AA concentrations applied. The collected microspheres were physically stable in terms of their dav and CV for >10 days of storage at 40°C. The aqueous microspheres exhibited ⌊-AA encapsulation efficiency exceeding 70% during the storage.

Feasibility and acceptability of reducing workplace sitting time: a qualitative study with Australian office workers

BACKGROUND: Office workers spend a large proportion of their working hours sitting. This may contribute to an increased risk of chronic disease and premature mortality. While there is growing interest in workplace interventions targeting prolonged sitting, few qualitative studies have explored workers' perceptions of reducing occupational sitting outside of an intervention context. This study explored barriers to reducing office workplace sitting, and the feasibility and acceptability of strategies targeting prolonged sitting in this context.

METHODS: Semi-structured interviews were conducted with a convenience sample of 20 office workers (50 % women), including employees and managers, in Melbourne, Australia. The three organisations (two large, and one small organisation) were from retail, health and IT industries and had not implemented any formalised approaches to sitting reduction. Questions covered barriers to reducing sitting, the feasibility of potential strategies aimed at reducing sitting, and perceived effects on productivity. Interviews were audiotaped and transcribed verbatim. Data were analysed using thematic analysis.

RESULTS: Participants reported spending most (median: 7.2 h) of their working hours sitting. The nature of computer-based work and exposure to furniture designed for a seated posture were considered to be the main factors influencing sitting time. Low cost strategies, such as standing meetings and in-person communication, were identified as feasible ways to reduce sitting time and were also perceived to have potential productivity benefits. However, social norms around appropriate workplace behaviour and workload pressures were perceived to be barriers to uptake of these strategies. The cost implications of height-adjustable workstations influenced perceptions of feasibility. Managers noted the need for an evidence-based business case supporting action on prolonged sitting, particularly in the context of limited resources and competing workplace health priorities.

CONCLUSIONS: While a number of low-cost approaches to reduce workplace sitting are perceived to be feasible and acceptable in the office workplace, factors such as work demands and the organisational social context may still act as barriers to greater uptake. Building a supportive organisational culture and raising awareness of the adverse health effects of prolonged sitting may be important for improving individual-level and organisational-level motivation for change.

Progress achieved in restricting the marketing of high-fat, sugary and salty food and beverage products to children

In May 2010, 192 Member States endorsed Resolution WHA63.14 to restrict the marketing of food and non-alcoholic beverage products high in saturated fats, trans fatty acids, free sugars and/or salt to children and adolescents globally. We examined the actions taken between 2010 and early 2016 - by civil society groups, the World Health Organization (WHO) and its regional offices, other United Nations (UN) organizations, philanthropic institutions and transnational industries - to help decrease the prevalence of obesity and diet-related noncommunicable diseases among young people. By providing relevant technical and policy guidance and tools to Member States, WHO and other UN organizations have helped protect young people from the marketing of branded food and beverage products that are high in fat, sugar and/or salt. The progress achieved by the other actors we investigated appears variable and generally less robust. We suggest that the progress being made towards the full implementation of Resolution WHA63.14 would be accelerated by further restrictions on the marketing of unhealthy food and beverage products and by investing in the promotion of nutrient-dense products. This should help young people meet government-recommended dietary targets. Any effective strategies and actions should align with the goal of WHO to reduce premature mortality from noncommunicable diseases by 25% by 2025 and the aim of the UN to ensure healthy lives for all by 2030.

Typography and the branding of culture: a methodological investigation into the way typography is used to brand cultural festivals in Australia

The observance of and participation in festivals and celebratory events is an increasingly significant aspect of the contemporary experience (Picard & Robinson, 2006). With the prestige that comes from holding culturally relevant and socially acceptable festivals that serve the discourses of “city branding” and the “creative industries” in a competitive global context; significant government, community and private funding is allocated to such events. Festivals have become a central figure of not only the political economy of tourism but also of urban regeneration and cultural tourism. Cultural festivals possess the hallmarks of destination branding or place branding and inadvertently share some of the attributes that influence visitors’ decisions to visit such destinations (Blain, Levy, & Ritchie, 2005; Cooper, 2005; Esu & Arrey, 2009; Jayswal, 2008). Branding is a vital part of this festival space and relies on typography to establish the symbolic values and representations of urban freedoms; rich histories, cultured places, playfulness and stimulation that seek to subvert our daily existence while performing the task of engaging local, national, and international visitors and participants. However, professional practices demonstrated in the design, media and arts industries have far outpaced the extent to which this phenomenon has been written about in the academic or public realm. What this paper intends is to interrogate appropriate semiotic approaches in an effort to analysing the discursive practices of typography as it performs in service to branding cultural festivals in Australia. The intention is to establish a methodology suited to the significant role typography performs within this context and to offer a contribution to design research that not only engages with the artefacts of design but with the conceptualization of designed meaning in 21st century visual culture.

Isolation and polyphasic characterization of a novel hyper catalase producing thermophilic bacterium for the degradation of hydrogen peroxide.

A newly isolated microbial strain of thermophilic genus Geobacillus has been described with emphasis on polyphasic characterization and its application for degradation of hydrogen peroxide. The validation of this thermophilic strain of genus Geobacillus designated as BSS-7 has been demonstrated by polyphasic taxonomy approaches through its morphological, biochemical, fatty acid methyl ester profile and 16S rDNA sequencing. This thermophilic species of Geobacillus exhibited growth at broad pH and temperature ranges coupled with production of extraordinarily high quantities of intracellular catalase, the latter of which as yet not been reported in any member of this genus. The isolated thermophilic bacterial culture BSS-7 exhibited resistance against a variety of organic solvents. The immobilized whole cells of the bacterium successfully demonstrated the degradation of hydrogen peroxide (H2O2) in a packed bed reactor. This strain has potential application in various analytical and diagnostic methods in the form of biosensors and biomarkers in addition to applications in the textile, paper, food and pharmaceutical industries.
