Co-morbid depression is associated with poor work outcomes in persons with cardiovascular disease (CVD) : a large, nationally representative survey in the Australian population

Background: Co-morbid major depressive disorder (MDD) and cardiovascular disease (CVD) is associated with poor clinical and psychological outcomes. However, the full extent of the burden of, and interaction between, this co-morbidity on important vocational outcomes remains less clear, particularly at the population level. We examine the association of co-morbid MDD with work outcomes in persons with and without CVD.

Methods. This study utilised cross-sectional, population-based data from the 2007 Australian National Survey of Mental Health and Wellbeing (n = 8841) to compare work outcomes of individuals with diagnostically-defined MDD and CVD, MDD but not CVD, CVD but not MDD, with a reference group of "healthy" Australians. Workforce participation was defined as being in full- or part-time employment. Work functioning was measured using a WHO Disability Assessment Schedule item. Absenteeism was assessed using the 'days out of role' item.

Results: Of the four groups, those with co-morbid MDD and CVD were least likely to report workforce participation (adj OR:0.4, 95% CI: 0.3-0.6). Those with MDD only (adj OR:0.8, 95% CI:0.7-0.9) and CVD only (adj OR:0.8, 95% CI: 0.6-0.9) also reported significantly reduced odds of participation. Employed individuals with co-morbid MDD and CVD were 8 times as likely to experience impairments in work functioning (adj OR:8.1, 95% CI: 3.8- 17.3) compared with the reference group. MDD was associated with a four-fold increase in impaired functioning. Further, individuals with co-morbid MDD and CVD reported greatest likelihood of workplace absenteeism (adj. OR:3.0, 95% CI: 1.4-6.6). Simultaneous exposure to MDD and CVD conferred an even greater likelihood of poorer work functioning.

Conclusions: Co-morbid MDD and CVD is associated with significantly poorer work outcomes. Specifically, the effects of these conditions on work functioning are synergistic. The development of specialised treatment programs for those with co-morbid MDD and CVD is required.

Contact lens prescribing in the Australian states and territories 2001

Background: This study was conducted to ascertain current preferences for contact lens prescribing in the Australian states and territories.

Methods: One thousand questionnaires were randomly distributed to proportionate samples of optometrists in each state of Australia. We requested details of the first 10 patients fitted with contact lenses after receipt of the questionnaire.

Results: One hundred and seventy-eight completed questionnaires were returned, detailing contact lens fits to 1,611 patients. The mean age of the patient group was 32.1 $pL 13.0 yrs (65 per cent female). For Australia as a whole: 53 per cent of patients were existing wearers, the remainder were new fits; 93 per cent of new fits were with soft lenses, of which seven per cent were for extended wear. Of the refits, 89 per cent were soft lenses and 18 per cent for extended wear. The lens material of first choice was mid-water-content (62 per cent of all soft lens fits). Only eight per cent of all soft fits were for lenses that were not replaced on a planned basis, with two weeks being the replacement interval of choice in all states and territories. The majority of rigid lenses were prescribed using mid-Dk materials (50 per cent). Analysis of solution prescribing indicates that multi-purpose products were the most common regimens for planned replacement soft lenses. The percentage of hydrogen peroxide prescribed increased as lens replacement became less frequent. By state or territory: practitioners in Tasmania prescribed more extended wear than those in any other state (p = 0.007) and practitioners in Queensland prescribed more daily disposable contact lenses than those in any other state (p = 0.009).

Conclusions: Non-planned replacement lenses are now rarely prescribed to patients. Extended-wear lenses and rigid lenses continue to be prescribed more to existing contact lens wearers than to new patients. The impact of soft multifocal lens designs on contact lens prescribing is very small, ranging from 2.6 per cent in Queensland to 4.7 per cent in Victoria, despite 20 per cent of patients being more than 45 years of age.

Introduction : making Indigenous place in the Australian city

This introductory essay situates this special issue's concerns in the context of Indigenous cultural centre design in settler-colonial Australia. Given the very small number of Indigenous architects in Australia, architectural facilities for Indigenous communities are routinely designed by non-indigenous architects. The implications of this are significant. Given the often complex social, historical and political ambitions that are invested in the construction of Indigenous cultural centres, and their frequent intention to represent a broad Indigenous constituency, can non-indigenous architectural and spatial practice ever realize these? As a way into this question, the essay surveys postcolonial and architectural scholarship that explores the spatialization of setter-colonial politics and the distinct place-making traditions of Indigenous and non-indigenous Australians. The making of place in the Australian city is an ongoing force of conflict, assertion, exclusion and forgetting, but it is also central to the realization of a possible post-colonial state in which no one ‘centre’ can ever stabilize and resolve questions of legitimacy and power. Instead, such a centre might hold these questions in tension and as questions in common, which would mean a new foundation for the making of place.

Promotional competitions: management decision-making in the Australian consumer marketplace

This research focused on a specific form of sales promotion: promotional competitions. The work identified the processes that organizations applied when defining their marketing strategy and promotional mix, and investigated the decision influences and design considerations which shaped the profile of competitions, offering innovative decision-making models for academics and practitioners.

John Mystery and the Australian book trade

The John Mystery books are a collection of Australian children's books and ephemera produced by a little known publishing dynamo, Lester Sinclair, in the middle of the twentieth century. I identify factors which operated to position these items as forgotten elements of Australian literary history. After contextualizing the John Mystery brand of children's books, I suggest how children's literature scholars may find potential resources in the Children's Literature Collection and other heritage collections of the State Library of Victoria.

Changes in muscle composition during the development of diving ability in the Australian fur seal

During development the Australian fur seal transitions from a terrestrial, maternally dependent pup to an adult marine predator. Adult seals have adaptations that allow them to voluntarily dive at depth for long periods, including increased bradycardic control, increased myoglobin levels and haematocrit. To establish whether the profile of skeletal muscle also changes in line with the development of diving ability, biopsy samples were collected from the trapezius muscle of pups, juveniles and adults. The proportions of different fibre types and their oxidative capacity were determined. Only oxidative fibre types (Type I and IIa) were identified, with a significant change in proportions from pup to adult. There was no change in oxidative capacity of Type I and IIa fibres between pups and juveniles but there was a two-fold increase between juveniles and adults. Myoglobin expression increased between pups and juveniles, suggesting improved oxygen delivery, but with no increase in oxidative capacity, oxygen utilisation within the muscle may still be limited. Adult muscle had the highest oxidative capacity, suggesting that fibres are able to effectively utilise available oxygen during prolonged dives. Elevated levels of total creatine in the muscles of juveniles may act as an energy buffer when fibres are transitioning from a fast to slow fibre type.

The volume and volatility relation in the Australian stock market

The thesis studies the volume-volatility relation in the Australian Securities Market. It is concluded that the number of trades is the most important variable driving realized volatility. The average trade size is significant but its explanatory power is only trivial. Order imbalance does not drive volatility in the Australian market.

Crowdsourcing motivations in a not-for-profit GLAM context : the Australian newspapers digitisation program

Crowdsourcing in recent times has become popular among not-for-profits as a means of eliciting members of the public to contribute to activities that would normally have been carried out by staff or by contracting external expertise. The GLAM (galleries, libraries, archives, museums) sector does have a history of involving online volunteers (e.g. reviewing books). Extending that tradition, some GLAM institutions are engaging in crowdsourcing projects to enhance and enrich their collections. But what motivates the public to participate in these crowdsourcing activities? Understanding the unique motivations of participants is needed to establish a motivational framework for GLAM organisations in their not-for-profit context. We present findings from a study of the motivational factors affecting participation in the Australian Newspapers Digitisation Program (ANDP) by the National Library of Australia (NLA). Based on motivational theories and frameworks the study shows that the participants are motivated by a complex framework of personal, collective and external factors. Participants were highly intrinsically motivated, but valued altruistic and community motivations as well. Community and external factors played a vital role in their continued involvement. The paper concludes with a conceptual framework of the motivational factors for crowdsourcing participants in a GLAM context based on the motivational dynamics observed in the ANDP case.
