Measures of transit accessibility are important in evaluating transit services, planning for future services and investment on land use development. Existing tools measure transit accessibility using averaged walking distance or walking time to public transit. Although the mode captivity may have significant implications on one’s willingness to walk to use public transit, this has not been addressed in the literature to date. Failed to distinguish transit captive users may lead to overestimated ridership and spatial coverage of transit services. The aim of this research is to integrate the concept of transit captivity into the analysis of walking access to public transit. The conventional way of defining “captive” and “choice” transit users showed no significant difference in their walking times according to a preliminary analysis. A cluster analysis technique is used to further divide “choice” users by three main factors, namely age group, labour force status and personal income. After eliminating “true captive” users, defined as those without driver’s licence or without a car in respective household, “non-true captive” users were classified into a total of eight groups having similar socio-economic characteristics. The analysis revealed significant differences in the walking times and patterns by their level of captivity to public transit. This paper challenges the rule-of-thumb of 400m walking distance to bus stops. In average, people’s willingness to walk dropped drastically at 268m and continued to drop constantly until it reached the mark of 670m, where there was another drastic drop of 17%, which left with only 10% of the total bus riders willing to walk 670m or more. This research found that mothers working part time were the ones with lowest transit captivity and thus most sensitive to the walking time, followed by high-income earners and the elderly. The level of captivity increases when public transit users earned lesser income, such as students and students working part time.

- Objective This study examined chronic disease risks and the use of a smartphone activity tracking application during an intervention in Australian truck drivers (April-October 2014). - Methods Forty-four men (mean age=47.5 [SD 9.8] years) completed baseline health measures, and were subsequently offered access to a free wrist-worn activity tracker and smartphone application (Jawbone UP) to monitor step counts and dietary choices during a 20-week intervention. Chronic disease risks were evaluated against guidelines; weekly step count and dietary logs registered by drivers in the application were analysed to evaluate use of the Jawbone UP. - Results Chronic disease risks were high (e.g. 97% high waist circumference [≥94 cm]). Eighteen drivers (41%) did not start the intervention; smartphone technical barriers were the main reason for drop out. Across 20-weeks, drivers who used the Jawbone UP logged step counts for an average of 6 [SD 1] days/week; mean step counts remained consistent across the intervention (weeks 1–4=8,743[SD 2,867] steps/day; weeks 17–20=8,994[SD 3,478] steps/day). The median number of dietary logs significantly decreased from start (17 [IQR 38] logs/weeks) to end of the intervention (0 [IQR 23] logs/week; p<0.01); the median proportion of healthy diet choices relative to total diet choices logged increased across the intervention (weeks 1–4=38[IQR 21]%; weeks 17–20=58[IQR 18]%). - Conclusions Step counts were more successfully monitored than dietary choices in those drivers who used the Jawbone UP. - Implications Smartphone technology facilitated active living and healthy dietary choices, but also prohibited intervention engagement in a number of these high-risk Australian truck drivers.

Consumer Sentiment fell by 4.8% in December, but despite the drop other indicators still point toward a robust Christmas period for retailers. Retail trade recorded its strongest result for three consecutive months to October, with Queensland and Western Australia leading the way. A closer inspection of ABS Retail figures indicate six consecutive months of positive results and this suggests consumer confidence has finally returned to the market. But it may not be a rosy outlook for all retail sectors. Overall we are spending more, but not where we once traditionally did.

Small firms are always vulnerable to complex technological change that may render their existing business model obsolete. This paper emphasises the need to understand how the Internet's ubiquitous World Wide Web is impacting on their operating environments. Consideration of evolutionary theory and the absorptive capacity construct provides the foundation for discussion of how learning and discovery take place within individuals, firms and the environments that interact with. Small firms, we argue, face difficulties identifying what routines and competencies are best aligned with the seemingly invisible dominant designs that support pursuit of new enterprise in web-impacted environments. We argue that such difficulties largely relate to an inability to acquire external knowledge and the subsequent reliance on existing internal selection processes that may reinforce the known, at the expense of the unknown. The paper concludes with consideration as to how managers can overcome the expected difficulties through the development of internal routines that support the continual search, evaluation and acquisition of specific external knowledge.

We’ve recently seen some encouraging improvements in closing the gap on Indigenous disadvantage: better educational outcomes, higher child immunisation rates, more health checks, and a 35% drop in the gap between Indigenous and non-Indigenous child deaths. But Aboriginal and Torres Strait Islander people continue to suffer a much greater burden of ill-health than other Australians. The gap in Indigenous life expectancy at birth remains unacceptably high at 10.6 years for men and 9.5 years for women. Three-quarters of Indigenous deaths are from potentially avoidable causes. These include preventable conditions such as type 2 diabetes, cardiovascular disease and some cancers. A major contributor to these preventable conditions is excess body weight.

Impending changes in Australian education brings forth the expected transformation of teachers working in schools. Three key points for transforming Australian schools has been identified by Gillard (2008a) including the improvement of quality teaching, ensuring every child benefits and mandating transparency and accountability. A number of initiatives were considered to assist with such reform including the implementation of a Digital Education Revolution, the move to the Australian Curriculum and the implementation of a National Framework for Professional Standards for Teaching. As these transformative initiatives are rolled out to teachers across Australia, the equitable access to PD to support all teachers, regardless of their geographical location, is in question. In line with the literature, the author proposes the concept of delivering PD and accessing PD from regional and remote areas be reconsidered. This research paper will outline the findings from the study including travel time being significant and impacting on teachers personal time; limited relief teachers impacting on access to PD; promotion and teacher registration being explicitly linked to PD; professional learning communities being valued but often limited by small staff numbers; professional learning conducted in the local context being preferred; professional learning established at the teacher and school level being desirable; teachers being confident in using technology and accessing PD online if required; and social cohesiveness being valued and often limited by isolation. Further this research has culminated in the development of a conceptual framework that would facilitate improving the amount and variety of professional learning available to regional and remote teachers.

This research consists of a broad study in three parts of the social and environmental reporting practices of organisations operating in or sourcing products from a developing country, in this case Bangladesh. The first part of this study explores the social and environmental disclosure practices of the Bangladesh Garment Manufacturers and Exporters Association (BGMEA), the body responsible for organising the activities of 4,200 entities involved in the export of garments from Bangladesh. By way of interview, this part documents the opinions of numerous senior executives from the BGMEA with regard to any changes in the degree of social and environmental pressures since 1985. Utilising a complementary theoretical perspective that includes legitimacy theory, stakeholder theory and institutional theory this part then performs an analysis of the BGMEA's annual reports (1987-2005), t o explore the link between the perceived pressures and changes entailed therein and the social and environmental disclosure practices of the BGMEA across the period of analysis. The results show that the disclosure practices of BGMEA appear to be directly driven by the changing expectations of multinational buying companies- the group deemed to be the most powerful stakeholder group. This section is the first known study to interview managers from a large organisation in a developing country about shifting stakeholder expectations and then to link these changing expectations to annual report disclosures across an extended period of analysis. The findings then directly lead to the second major part of this thesis which investigates the social and environmental disclosure practices of two major multinational buying companies: Nike and H&M. Adopting a joint consideration of legitimacy theory and media agenda setting theory, this second part investigates the linkage between negative media attention and positive corporate social and environmental disclosures over a 19 year period. The results support the view that for those industry-related social and environmental issues that attract the greatest amount of negative media attention, these companies react by providing positive social and environmental disclosures. The results were particularly significant in relation to labour practices in developing countries-the issue that attracts the greatest amount of negative media attention for the companies in question. While the second part demonstrates that the media influences particular disclosure practices, the third part of the thesis shows what drives the media. Based on the speculation provided in the second part, the third part tests the proposition that the media is an important ally of NGOs in their quest to influence change in corporate accountabilities. Through the use of interviews, the results of this part of the study provide evidence to support previously untested perspectives about NGOs' utilisation of the m edia. The results reveal that NGOs use the media because the media is responsible for creating real changes in the operations and disclosure policies of organisations sourcing products from Bangladesh. The various pressures impacting the activities of organisations operating in or sourcing products from developing countries constitutes a fascinating area of investigation, and it is hoped that this study will motivate further research in this area.

What is the future for public health in the twenty-first century? Can we glean an idea about the future of public health from its past? As Winston Churchill once said: ‘[T]he further backward you look, the further forward you can see.’ What can we see in the history of public health that gives us an idea of where public health might be headed in the future? (Gruszin et al. 2012). In the twentieth century there was substantial progress in public health in Australia. These improvements were brought about through a number of factors. In part, improvements were due to increasing knowledge about the natural history of disease and its treatment. Added to this knowledge was a shifting focus from legislative measures to protect health, to the emergence of improved promotion and prevention strategies, and a general improvement in social and economic conditions for people living in countries such as Australia. Gruszin et al. (2012) consider the range of social and economic reforms of the twentieth century as the most important determinants of the public’s health at the start of the twenty-first century (Gruszin et al. 2012 p 201). The same could not, however, be said for second or third world countries, many of whom have the most fundamental of sanitary and health protection issues still to deal with. For example, in sub-Saharan Africa and in Russia the decline in life expectancy can be said to be related to a range of interconnected factors. In Russia, issues such as alcoholism, violence, suicide, accidents and cardiovascular disease could be contributing to the falling life expectancy (McMichael & Butler 2007). In sub-Saharan Africa, a range of factors, such as HIV/AIDS, poverty, malaria, tuberculosis, undernutrition, totally inadequate infrastructure, gender inequality, conflict and violence, political taboos and a complete lack of political will, have all contributed to a dramatic drop in life expectancy (McMichael & Butler 2007).

An important application of solar thermal storage is for power generation or process heating. Low-temperature thermal storage in a packed rock bed is considered the best option for thermal storage for solar drying applications. In this chapter, mathematical formulations for conical have been developed. The model equations are solved numerically for charging/discharging cycles utilizing MATLAB. Results were compared with rock-bed storage with standard straight tank. From the simulated results, the temperature distribution was found to be more uniform in the truncated conical rock-bed storage. Also, the pressure drop over a long period of time in the conical thermal storage was as low as 25 Pa. Hence, the amount of power required from a centrifugal fan would be significantly lower. The flow of air inside the tank is simulated in SolidWorks software. From flow simulation, 3D modelling of flow is obtained to capture the actual scenario inside the tank.

An important application of thermal storage is solar energy for power generation or process heating. Low temperature thermal storage in a packed rock bed is considered best option for thermal storage for solar drying applications. In this paper, mathematical formulations for conical and cylindrical rock bed storage tanks have been developed. The model equations are solved numerically for charging/discharging cycles. From the simulated results, it was observed that for the same aspect ratio between the diameter and the length of the thermal storages, the conical thermal storage had better performance. The temperature distribution was found to be more uniform in the truncated conical shape rock bed storage. Also, the pressure drop over long period of time in the conical thermal storage was lower than that of the cylindrical thermal storage. Hence, the amount of power required from a centrifugal fan was lower.

Over the last few decades, geotextiles have progressively been incorporated into geotechnical applications, especially in the field of coastal engineering. Geotextile materials often act as separator and a filter layer between rocks laid above and subgrade beneath. This versatile material has gradually substituted traditional granular materials because of its ease of installation, consistent quality and labour costefficiency. However, geotextiles often suffer damage during installation due to high dynamic bulk loading of rock placement. This can degrade geotextiles' mechanical strength. The properties considered in this paper include the impact resistance and retained strength of geotextiles. In general, the greater the impact energy applied to geotextiles, the greater the potential for damage. Results highlight the inadequacy of using index derived values as an indicator to determine geotextile performance on site because test results shows that geotextiles (staple fibre (SF) and continuous filament (CF)) with better mechanical properties did not outperform lower mechanical strength materials. The toughest CF product with a CBR index value of 9696N shows inferior impact resistance compared to SF product with the least CBR strength (2719N) given the same impact energy of 9.02 kJ. Test results also indicated that the reduction of strength for CF materials were much greater (between 20 and 50%) compared to SF materials (between 0 and 5%) when subjected to the same impact energy of 4.52 kJ.

Amongst social players, the prank, as a social performance form, holds a lot of potential to impact on personal, relational and social status within a group or between one group and another group. More than simply showing off, a prank in the strictest definition of the term, is a social performance in which one player, a prankster, deploys mischief, trickery or deceit, to cause a moment of anxiety, fear or anger about a happening for another spectator-become-collaborating-player, a prankee – to enhance social bonds, entertain, or comment on a social, cultural or political phenomenon. During a prank, the prankster’s ability to be creative, clever or culturally astute, and the prankee’s ability to be duped, be a good sport, play along, or even play/pay the prankster back, both become fodder for other spectators and society to scrutinize. In Australia, pranking traditions are popular with many social groups, from the community-building pranks of footballers, bucks parties and ‘drop bear’ tales told to tourists, to the more controversial pranks of radio shock jocks, activists and artists. In this paper, I consider whether theatrical terms – theoretical terms from the stage such as actor, acting, objective, arc, performance, audience and emotion, such as those offered by Joseph Roach – are useful in understanding the passion some social players show for pranksterism. Are theatrical terms such as Roach’s as useful as analysts of social self-performance such as Erving Goffman suggest they are? Do they assist in understanding the personal actions, reactions and emotions of prankster and prankee? Do they assist in understanding the power relations between prankster and prankee? Do they assist in understanding the relation between the prank – be it an everyday prank amongst families, friends and coworkers, an entertainment program prank of the sort seen on Prank Patrol, Punked or Scare Tactics, or an activist pranks perpetrated by a guerrilla artist, ‘jammers’ or ‘hackers’ intent on turning dominant social systems back on themselves – the social players, and the public sphere in which the prank takes place? I reflect on how reading pranks as performances, by players, for highly participatory audiences, helps understand why they are so prevalent, and so recurrent across times, cultures and contexts, and also so controversial when not performed well enough – or when performed too well – prompting outrage from the prankster, prankee or society as passionate as any debate about a performance by players in a theatre.

In common law jurisdictions such as England, Australia, Canada and New Zealand good faith in contracting has long been recognised in specific areas of the law such as insurance law and franchising, and more recently the implied duties of good faith and mutual trust and convenience in employment contracts have generated a considerable volume of case law. Outside of these areas of law that may be characterised as being strongly‘relational’ in character,the courts in common law jurisdictions have been reluctant to embrace a more universal application of good faith in contracting and performance. However increasingly there are cases which support the proposition that there is a common law duty of good faith of general application to all commercial contracts. Most important in this context is the recent decision of the Supreme Court of Canada in Bhasin v Hrynew.1 However, this matter is by no means resolved in all common law jurisdictions. This article looks at the recent case law and literature and at various legislative incursions including statutes, codes of conduct and regulations impacting good faith in commercial dealings.

Carers are at the frontline working with children in the care of the child protection system. This paper reports carer's views about key factors influencing the placement trajectories of children and young people living in out-of-home care in Queensland, Australia. The study sample included 21 foster and kinship carers with a minimum two-year experience in the carer role. Study data were from semi-structured telephone interviews in which carers shared their experiences of the factors impacting upon placement stability and placement movement. Carers' responses were analysed thematically. Data analysis yielded an overarching theme regarding placement trajectory: Carer engagement, and its three sub-themes; with the child; with the child protection system; and, with the caring role. Findings suggested that carer engagement and ‘fit’ are complex constructs that play critical influential roles in placement outcomes (stability or movement) for individual children in out-of-home care. It is argued that practice needs to be better grounded in these relational dynamics, and better aligned concerning the power differentials that exist.

One significant factor influencing student wellbeing is the degree to which their studies are subject to external lifestyle pressures. These pressures are relieved or exacerbated by choices students make around their approaches to study, and the amount of time they devote to work and leisure. This Chapter considers results from a 2012 survey of law students at the University of New South Wales (UNSW), Sydney, Australia. Those results are compared to results from a similar US law student survey, and comparable data from the UK and Australia more broadly. In addition, the UNSW study compares key lifestyle choices of undergraduate (LLB) and graduate (JD) law students. The significance of the analysis in this Chapter for understanding law students’ wellbeing is that comparing American and Australian law students’ lifestyle patterns provides insights into contextual variation between both groups, which is important to bear in mind when comparing American and Australian research on law students’ wellbeing, and appreciating the limits of such comparisons. In particular, much of the wellbeing literature to date has focused on course-based stressors, but in light of recent research indicating that improvements in students’ course-based experiences may not have a direct effect on law students’ elevated levels of psychological distress, it is important to understand the broader life pressures and stressors that may be impacting law students’ wellbeing.
