Simple Question, Complex Answer : Pathways Towards a 50% Decrease in Building Energy Use

Addressing building energy use is a pressing issue for building sector decision makers across Europe. In Sweden, some regions have adopted a target of reducing energy use in buildings by 50% until 2050. However, building codes currently do not support as ambitious objectives as these, and novel approaches to addressing energy use in buildings from a regional perspective are called for. The purpose of this licentiate thesis was to provide a deeper understanding of most relevant issues with regard to energy use in buildings from a broad perspective and to suggest pathways towards reaching the long-term savings objective. Current trends in building sector structure and energy use point to detached houses constructed before 1981 playing a key role in the energy transition, especially in the rural areas of Sweden. In the Swedish county of Dalarna, which was used as a study area in this thesis, these houses account for almost 70% of the residential heating demand. Building energy simulations of eight sample houses from county show that there is considerable techno-economic potential for energy savings in these houses, but not quite enough to reach the 50% savings objective. Two case studies from rural Sweden show that savings well beyond 50% are achievable, both when access to capital and use of high technology are granted and when they are not. However, on a broader scale both direct and indirect rebound effects will have to be expected, which calls for more refined approaches to energy savings. Furthermore, research has shown that the techno-economic potential is in fact never realised, not even in the most well-designed intervention programmes, due to the inherent complexity of human behaviour with respect to energy use. This is not taken account of in neither current nor previous Swedish energy use legislation. Therefore an approach that considers the technical prerequisites, economic aspects and the perspective of the many home owners, based on Community-Based Social Marketing methodology, is suggested as a way forward towards reaching the energy savings target.

The first 50 years of the annual endowed accounting research lecture series at the University of Melbourne

Carnegie and Edwards (2001) suggest that the formation of an organisational body is just one of the 'signals of movement' within the dynamic process of professionalisation of an occupation and they list the sponsoring of professorial posts and research activities at universities as further examples. While the literature on this process in Australia does refer to the sponsorship of chairs of accounting (Carnegie & Williams, 2001), little has been written identifying the range of other areas of sponsorship by the organised accounting bodies. This paper presents details of the first fifty years presentations of the Annual Accounting Research Lectures held at The University of Melbourne, Australia. They have been presented continuously since 1940, when they were inaugurated with sponsorship from the Commonwealth Institute of Accountants. The paper presents the first complete listing of details relating to the presenter (including name, gender, residency and occupational area), title of the paper, date of presentation (where known) and details of publication (where appropriate). The initial and subsequent motivation for the presentation of the series and the influence of the lectures in promoting research and fostering relations between the professional bodies and the university, during a period of great significance in the development of accounting education and the professionalisation of accounting in Australia, is also discussed.

Use of calcium or calcuim in combination with vitamin D supplementation to prevent fractures and bone loss in people aged 50 years and older: a meta-analysis

Background:  Whether calcium supplementation can reduce osteoporotic fractures is uncertain. We did a meta-analysis to include all the randomised trials in which calcium, or calcium in combination with vitamin D, was used to prevent fracture and osteoporotic bone loss.

Methods:  We identified 29 randomised trials (n=63 897) using electronic databases, supplemented by a hand-search of reference lists, review articles, and conference abstracts. All randomised trials that recruited people aged 50 years or older were eligible. The main outcomes were fractures of all types and percentage change of bone-mineral density from baseline. Data were pooled by use of a random-effect model.

Findings:  In trials that reported fracture as an outcome (17 trials, n=52 625), treatment was associated with a 12% risk reduction in fractures of all types (risk ratio 0·88, 95% CI 0·83–0·95; p=0·0004). In trials that reported bone-mineral density as an outcome (23 trials, n=41 419), the treatment was associated with a reduced rate of bone loss of 0·54% (0·35–0·73; p<0·0001) at the hip and 1·19% (0·76–1·61%; p<0·0001) in the spine. The fracture risk reduction was significantly greater (24%) in trials in which the compliance rate was high (p<0·0001). The treatment effect was better with calcium doses of 1200 mg or more than with doses less than 1200 mg (0·80 vs 0·94; p=0·006), and with vitamin D doses of 800 IU or more than with doses less than 800 IU (0·84 vs 0·87; p=0·03).

Interpretation:  Evidence supports the use of calcium, or calcium in combination with vitamin D supplementation, in the preventive treatment of osteoporosis in people aged 50 years or older. For best therapeutic effect, we recommend minimum doses of 1200 mg of calcium, and 800 IU of vitamin D (for combined calcium plus vitamin D supplementation).

Understanding women's breast screening behaviour: a study carried out in South East London, with women aged 50-64 years

Objective To understand low uptake of breast cancer screening through exploring the personal reasoning underlying women's attendance or non-attendance, and identifying differences between those who attend and those who decline.

Design Cross-sectional survey.

Setting Community and home environments of women eligible for breast screening aged 50—64 years, living in South East London. Method Structured, self-completed or assisted-completion questionnaires.

Results The decision to attend or decline screening is rational and personally justifiable, engaging factors linked to emotions and attitude. Attitudes about breast screening and perceived personal importance of breast screening are the strongest predictors of attendance and non-attendance. There are differences between ethnic groups in perceptions of breast screening. Regular attendance at screening is associated with ethnicity, although consistent avoidance of mammography is not. Inconvenience is an important factor in missing appointments, and tends to be prolonged rather than specific to the time or day of the pre-booked invitation. GP and health worker advice are good persuaders towards attendance. Pain and anxiety during mammography are notable dissuaders against re-attending.

Conclusion Appropriate service provision requires consideration of local factors, as well as the medical needs of the population eligible for breast screening. Lay perceptions of potential personal costs of attending or not attending breast screening are important for guiding health promotion. Information providers should consider the language needs of a culturally and educationally mixed community. Health care professionals are well placed to encourage uptake of breast screening through disseminating information that promotes attendance, both within and outside the breast screening service.

50 years of underground filmmaking in Melbourne: program 3

Program 3 of the 50 years of underground filmmaking in Melbourne, curated by Bill Mousoulis. A collection of John Cumming's films, including: Obsession, Recognition, and Sabotage. John also screened and discussed excerpts from some of his other works. The whole session was followed by discussion

Associations between adverse social position and bone mineral density in women aged 50 years or older: data from the Manitoba bone density program

The authors examined the independent contribution of income to low bone mineral density in women aged 50 years and older. A significant dose–response association was observed between low income and low (bone mineral density) BMD, which was not explained by clinical risk factors or osteoporotic treatment in the year prior.

The association between social disadvantage and osteoporosis is attracting increased attention; however, little is known of the role played by income. We examined associations between income and bone mineral density (BMD) in 51,327 women aged ≥50 years from Manitoba, Canada.
