We propose a novel re-ranking method for content-based medical image retrieval based on the idea of pseudo-relevance feedback (PRF). Since the highest ranked images in original retrieval results are not always relevant, a naive PRF based re-ranking approach is not capable of producing a satisfactory result. We employ a two-step approach to address this issue. In step 1, a Pearson's correlation coefficient based similarity update method is used to re-rank the high ranked images. In step 2, after estimating a relevance probability for each of the highest ranked images, a fuzzy SVM ensemble based approach is adopted to re-rank the images. The experiments demonstrate that the proposed method outperforms two other re-ranking methods.

Objective:
Conclusion:
BAEW was affordable and cost-effective, and generated substantial spin-offs in terms of activity beyond funding levels. Elements fundamental to its success and any potential cost efficiencies associated with scaling-up now require identification.

Methods:
Detailed survey completed by representatives from community-based obesity prevention initiatives in Australia.
Results:
There was wide variation in funding, capacity and approach to obesity prevention among the 78 participating projects. Median annual funding was Au$94 900 (range Au$2500–$4.46 million). The most common intervention settings were schools (39%). Forty per cent of programs focused on a population group of ≥50 000 people. A large proportion of respondents felt that they did not have sufficient resources or staff training to achieve project objectives.
Conclusion:
Community-based projects currently represent a very large investment by both government and non-government sectors for the prevention of obesity. Existing projects are diverse in size and scope, and reach large segments of the population. Further work is needed to identify the full extent of existing community actions and to monitor their reach and future ‘scale up’ to ensure that future activities aim for effective integration into systems, policies and environments.
So what?:
Community-based programs make a substantial contribution to the prevention of obesity and promotion of healthy lifestyles in Australia. A risk of the current intervention landscape is that effective approaches may go unrecognised due to lack of effective evaluations or limitations in program design, duration or size. Policy makers and researchers must recognise the potential contribution of these initiatives, to both public health and knowledge generation, and provide support for strong evaluation and sustainable intervention designs.

The paper aims to provide a brief overview of key ideas related to outcome measurement relevant to community based mental health services and their consumers in WA. Due to the breadth of scope of the paper, it is not an extensive or rigorous literature review but provides a scan of the literature that could shape a more thorough literature review in any of the content areas. The paper has been written with the aim of informing the sector of key ideas, issues, concepts and approaches.
