The impact of Indigenous community sports programs: the case of surfing

The objective of this research project was to consider the social impact of sport and physical activity on the lives of Indigenous Australians and their communities. There has been strong research interest in the links between sport and recreation programs and various health and social outcomes and a well-established body of literature exists on the use of sport to address social issues in mainstream society. The consensus is that physical activity is an important contributor to health for all people. While there is strong research interest, what remains unclear is the value and impact of sport and physical activity on Indigenous communities.Indigenous groups cannot be considered to be homogenous as there is much diversity between and within groups. It is therefore important this report is not viewed as taking an essentialist view of who Indigenous people are and how they develop. Rather, this paper attempts to describe and discuss the experiences of some individuals and their communities in site-specific surfing programs.The results of this project indicate that surfing should continue to be considered as an appropriate sport for use with Indigenous communities.It should be noted, however, that any program needs to take into consideration the diversity of Indigenous culture, how communities operate and should seek appropriate guidance.While there was great variety in terms of how surf programs in this study operated, there were some common elements across all programs including: strict surfer-to-coach ratios, opt-in opt-out structures and avoidance of controlling coach behaviours.In addition to these characteristics, quality programs also had consistency in personnel (small groups rather than single providers).This research project provided experience and information to develop recommendations relating to future similar programs including:Programs should be supported in longer term allotments Programs should collect meaningful data (well-constructed interview and survey protocols) over and above simple participation statistics To achieve meaningful outcomes, programs need continuity and should not be one-offs As transport costs represent the greatest barrier to participation in programs and surfing as a lifestyle pursuit, programs should consider the transport options most suitable for their area. Individuals who participated in the research highlighted that it can take a long time for the effects of programs to be felt. As a result, longitudinal tracking by program providers is required to provide ongoing evidence in support of programs. Funding to programs should also be sought across longer time frames to provide a greater platform to generate positive outcomes.Through this research it was possible to identify the development of individual and organisational capacity. In both areas, however, these capacities were not automatically enhanced. Careful planning and strong encouragement and support from program providers were required

A Neuroevolutionary Approach to Stochastic Inventory Control in Multi-Echelon Systems

Stochastic inventory control in multi-echelon systems poses hard problems in optimisation under uncertainty. Stochastic programming can solve small instances optimally, and approximately solve larger instances via scenario reduction techniques, but it cannot handle arbitrary nonlinear constraints or other non-standard features. Simulation optimisation is an alternative approach that has recently been applied to such problems, using policies that require only a few decision variables to be determined. However, to find optimal or near-optimal solutions we must consider exponentially large scenario trees with a corresponding number of decision variables. We propose instead a neuroevolutionary approach: using an artificial neural network to compactly represent the scenario tree, and training the network by a simulation-based evolutionary algorithm. We show experimentally that this method can quickly find high-quality plans using networks of a very simple form

Generalizing backdoors

Abstract. A powerful intuition in the design of search methods is that one wants to proactively select variables that simplify the problem instance as much as possible when these variables are assigned values. The notion of “Backdoor ” variables follows this intuition. In this work we generalize Backdoors in such a way to allow more general classes of sub-solvers, both complete and heuristic. In order to do so, Pseudo-Backdoors and Heuristic-Backdoors are formally introduced and then applied firstly to a simple Multiple Knapsack Problem and secondly to a complex combinatorial optimization problem in the area of stochastic inventory control. Our preliminary computational experience shows the effectiveness of these approaches that are able to produce very low run times and — in the case of Heuristic-Backdoors — high quality solutions by employing very simple heuristic rules such as greedy local search strategies.

Public health approach to prevent cervical cancer in HIV-infected women in Kenya : issues to consider in the design of prevention programs

Women living with HIV in Africa are at increased risk to be co-infected with Human Papilloma Virus (HPV), persistent high risk (HR) HPV infection and bacterial vaginosis (BV), which compounds HPV persistence, thereby increasing the risk for cervical dysplasia. New guidance from WHO in 2014 advocating for a "screen and treat" approach in resource poor settings is becoming a more widely recommended screening tool for cervical cancer prevention programs in such contexts. This review article summarizes the risk factors to be considered when designing a primary and secondary cervical prevention program in a post-vaccination era for HIV-infected women in Kenya. This review article is based on our prior research on the epidemiology of pHR/HR-HPV genotypes in HIV-infected women and CIN 2+ in Kenya and other sub-Saharan contexts. In order to contextualize the findings, a literature search was carried out in March 2017 by means of four electronic databases: PUBMED, EMBASE, SCOPUS, and PROQUEST. Risk factors for potential (pHR)/HR HPV acquisition, including CD4 count, HAART initiation, Female Sex Worker status (FSW) and BV need to be considered. Furthermore, there may be risk factors for abnormal cytology, including FSW status, multiple potential (p) HR/HR HPV genotypes, which may require that HIV-infected women be subjected to screening at more frequent intervals than the three year recommended by the WHO. The quadruple synergistic interaction between HIV, HPV and BV and its related cervicitis may need to be reflected within a larger prevention framework at the community level. The opportunities brought forth by the roll out of HAART could lead to task shifting of HIV-HPV-BV care to nurses, which may increase access in poorly-served areas

The Sports Demonstration Project - An initiative of the Australian Sports Commission: An Evaluation

The Sport Development Project (SDP) was a comprehensive youth strategy for sport in the Northern Territory aimed at diversion from ‘at-risk’ behaviours, improvement of life choices and outcomes, and strengthening youth service infrastructure through engagement in positive (sport) activities. There were five Remote Service Delivery sites that were involved in the trial of this ‘best practice’ model for delivering sport-focused diversion activities. These include: Gapuwiyak, Wadeye, Yuendumu, Gunbalunya and Nguiu

Empirical Measures of Judicial Performance: An Introduction to the Symposium

Inspired by the burgeoning empirical literature on the judiciary, the editors of the Florida State University Law Review have solicited some papers from leading scholars and federal courts of appeals judges, asking them to address the topic of empirical measures of judicial performance. The papers in this Symposium on Empirical Measures of Judicial Performance address empirical measures of judicial performance from a variety of methodological perspectives, but as this Foreword suggests, they can roughly be organized around three basic themes. First, many of the papers critique the empirical enterprise itself and especially the tournament strategy for evaluating judges, although these papers also raise important issues for future empirical study of judges. Second, many of the papers in the Symposium propose new ways of operationalizing the empirical study of judicial performance or present fresh new empirical evidence about judges and courts. Third, some of the papers focus on the behavioral and institutional implications or empirical studies of judges and courts. As the papers in the Symposium would indicate, the empirical tournament has inspired some important advances in the discourse about measurement of performance in the context of the judiciary and its relevance to the selection of judges and the judicial process. While efforts to measure judicial performance empirically simultaneously revive many old controversies and presents new issues, its debates will be certain to continue as long as we have data, judges, and courts
