Methodological reflections on using pilot data from fracture patients to develop a qualitative study

Background: Qualitative studies are particularly valued for their exploratory nature but, like other research methods, they do require careful planning to ensure rigorous study design. Our objective was to undertake a pilot study to inform the development of a larger qualitative study.

Results: We conducted a series of brief interviews with out-patients in a hospital setting. The interviews were designed to elicit superficial information about whether (and how) post-fracture osteoporosis investigation and/or treatment were being initiated among patients receiving treatment or follow-up for a current or recent fracture. We used thematic analysis to identify key themes in the data that related to the broader research questions. We analysed data obtained from 11 out of a total of 12 interviews conducted. Participants were male and female, aged 19-83 years of age (median age 57 years). Participants attended 2-8 medical appointments to seek treatment and follow up for a current or recent fracture. The following four overarching themes emerged from thematic analysis of the data: fracture event, referral pathway, osteoporosis investigation and/or treatment, and communication by health practitioners and staff.

Conclusions: This pilot study was necessarily tentative and exploratory in nature, but provided a helpful snapshot of some typical experiences in the public health system following fracture. Several themes emerged for consideration in the design of the main study. Despite its critics, theoretical sampling and saturation continue to provide sustainable methods for ensuring that relevant themes and categories are covered in sufficient depth and breadth, appropriate to the needs of the study.

The experience of Singapore in raising awareness of natural and cultural resources

The city-state of Singapore has a major role in the urban development. Majority of the innovative projects are initiated by the government agencies. For this paper, I would like to highlight the two distinct themes of innovation that, I believe preoccupied the authority for its urban issues, they are innovation which concern nature and culture. Land in Singapore is scarce. Natural resources are strictly protected. At the same time they are challenged to return the maximum benefit to their own population. The water catchment area and the prime forest on the whole island is the most valuable natural resources to be preserved. The paper will demonstrate how Singapore challenges with its own resources (water and greenery) in which the holistic planning around these themes become more than just spaces of protection but integrated with the public space system and turned into more valuable spaces for the well being of its population. The second theme is the issue related to culture. Singapore's economy is the most advance compare to other Southeast Asian countries, however when it comes to culture and identity, the city state struggles with the over constructed image of branding Singapore's culture. The paper will discuss several examples around the theme of arts and culture, how the city state bench-mark itself with the world class cities. It is one of the most challenging topic in urban planning and policy making. It is worth discussing on its success and failure. We can learn form Singapore that innovation at the level of policy maker can be achieved in some urban aspects such as the management of natural resources and urban design projects related to it. However when it comes to the issue related to art and culture, the top down policy alone cannot assure the achievement of city's identity as it aspired. Tracing the historical development of the environmental and cultural policies of Singapore the paper intends to study and analyze various case studies reflecting these attempts of natural and cultural instillation. In the process of comparison of these two drastically contrasting actors and approaches, the paper will argue that it has mostly been driven by economic aims, and careful thought. The results have been limited and restrictive. Further arguing that 'creativity' is the essential factor of arts and culture, it evaluates the authenticity and the ultimate implications on cultural spirit.

An analytical model for optimal spectrum leasing under constraints of quality of service in CRNs

Cognitive radio improves spectrum efficiency and mitigates spectrum scarcity by allowing cognitive users to opportunistically access idle chunks of the spectrum owned by licensed users. In long-term spectrum leasing markets, secondary network operators make a decision about how much spectrum is optimal to fulfill their users' data transmission requirements. We study this optimization problem in multiple channel scenarios. Under the constrains of expected user admission rate and quality of service, we model the secondary network into a dynamic data transportation system. In this system, the spectrum accesses of both primary users and secondary users are in accordance with stochastic processes, respectively. The main metrics of quality of service we are concerned with include user admission rate, average transmission delay and stability of the delay. To quantify the relationship between spectrum provisioning and quality of service, we propose an approximate analytical model. We use the model to estimate the lower and upper bounds of the optimal amount of the spectrum. The distance between the bounds is relatively narrow. In addition, we design a simple algorithm to compute the optimum by using the bounds. We conduct numerical simulations on a slotted multiple channel dynamic spectrum access network model. Simulation results demonstrate the preciseness of the proposed model. Our work sheds light on the design of game and auction based dynamic spectrum sharing mechanisms in cognitive radio networks.

Private protected areas in Australia: current status and future directions

Despite the recognised importance of private land for biodiversity conservation, there has been little research into systems of private protected areas at a country-wide level. Here I look at definitions, legislation, ownership, management approaches and effectiveness, distribution and incentives provided to private protected areas in Australia. The term 'private protected areas', although increasingly used, still suffers from a lack of a clear and concise definition in Australia. Australian states and territories have legislation enabling the application of conservation covenants over private land; covenants being the primary mechanism to secure conservation intent on the title of the land in perpetuity. If considering all 'in perpetuity' conservation covenants under a dedicated program to be private protected areas and land owned by non-government organisations and managed for the purpose of biodiversity conservation, there were approximately 5,000 terrestrial properties that could be considered private protected areas in Australia covering 8,913,000 ha as at September 2013. This comprises almost 4,900 conservation covenants covering over 4,450,000 ha and approximately 140 properties owned by private land trusts covering approximately 4,594,120 ha. Most conservation covenanting programs now seek to complement the comprehensiveness, adequacy and representativeness of the public reserve system, either stating so explicitly or by aiming to protect the highest priority ecosystems on private land. There are a range of incentives offered for private land conservation and requirements of owners of private protected areas to report on their activities vary in Australia. However, there are a number of key policy challenges that need to be addressed if private protected areas are to achieve their full potential in Australia, including managing broad-scale ecosystem processes, protection and tenure reform, improved financial incentives, and access to emerging ecosystem service markets.

Integrated health care: it's time for it to blossom

Considering the grim scenario of burgeoning health-care costs and cost-cutting measures by the Australian Government, there is a clear case to invest and research into disciplines that will ensure sustainability of the public health system. There is evidence that integrated health care contributes to a cost-efficient and quality health system because of potential benefits like streamlined care for patients, efficient use of resources, a better cover of patients and improved patient safety. However, integrated health care as a notion is submerged in the disciplines of public health and primary care. In reality, it is a distinct concept acting as a bridge between primary and secondary care. This article argues it is time for the discipline of integrated health care to be recognised on its own and investment be driven into the establishment of integrated care centres.
