Description: Retrospective data extraction from two complementary mortality datasets determined the descriptive epidemiology and population rates in unintentional drowning deaths at surf beaches (n = 129). The annual average crude surf beach drowning rate was 0.28 per 100 000 population for males and 2.36 per 100 000 population for international tourists. The study generated hypotheses for risk assessment to assist intervention: adult males, international tourists, people with cardiovascular conditions, and exposure to rip currents.

Description: In this paper we canvass a shift in professional practice for teachers and teaching and learning as it focuses on Design Education. We acknowledge that changes in formal educational settings result from the scope and rapidity of changes in emerging technologies and understandings of pedagogical influences on teaching and learning. In canvassing the changes, in this paper we identify issues that emerge in relation a number of proposed solutions in dealing with gaps in teacher education in the field of Design Education. We suggest that these same solutions draw on traditional disciplines which ignore the possibilities of Design to engage 21st Century problems in teaching and learning. We draw attention to a neglect in current teacher education programs in relation to teachers of design and what this may imply for classrooms, teachers, and their work.

Description: Prudence analysis (PA) is a relatively new, practical and highly innovative approach to solving the problem of brittleness in knowledge based systems (KBS). PA is essentially an online validation approach, where as each situation or case is presented to the KBS for inferencing the result is simultaneously validated. This paper introduces a new approach to PA that analyses the structure of knowledge rather than the comparing cases with archived situations. This new approach is positively compared against earlier systems for PA, strongly indicating the viability of the approach.

Description: This paper reports the reanalysis of data collected in a study of 3 determinants of classroom environment (viz. year level, subject, and school type) using multivariate analysis of variance and multilevel analysis. Data were collected from 2,211 students in Queensland Catholic and government schools. The Catholic School Classroom Environment Questionnaire, which assesses student affiliation, interactions, cooperation, task orientation, order and organisation, individualisation, and teacher control, was administered to the sample. The original multivariate analyses which used the class as the unit of analysis were supplemented by similar analyses using the student as the unit of analysis and multilevel analyses. While multilevel analyses yielded tests of significance results similar to multivariate analyses conducted with the class as the unit of analysis, effect sizes for the multilevel analyses were similar to those reported for multivariate tests conducted with the student as the unit of analysis.

Description: While urban areas are increasingly recognized as having potential value for biodiversity conservation, the relationship between biodiversity and the structure and configuration of the urban landscape is poorly understood. In this study we surveyed birds in 39 remnant patches of native vegetation of various sizes (range 1-107 ha) embedded in the suburban matrix in Melbourne, Australia. The total richness of species within remnants was strongly associated with the size of remnants. Remnant-reliant species displayed a much stronger response to remnant area than matrix-tolerant species indicating the importance of large remnants in maintaining representative bird assemblages. Large remnants are important for other ecological groups of species including migratory species, ground foraging birds and canopy foraging birds. Other landscape (e.g. amount of riparian vegetation) and structural components (e.g. shrub cover) of remnants have a lesser role in determining the richness of individual remnants. This research provides conservation managers and planners with a hierarchical process to reserve design and management in order to conserve the highest richness of native species within urban areas. First of all, conservation efforts should preferentially focus on the retention of larger remnants of native vegetation. Second, where possible, riparian vegetation should be included within reserves or, where it is already present, should be carefully managed to ensure its integrity. Third, efforts should be focused at maintaining appropriate habitat and vegetation structure and complexity. © 2008 Elsevier Ltd. All rights reserved.

Description: This paper will outline the key elements of my professional identity, giving the reader a portrait of how I will operate as a social welfare worker. My practice framework includes a discussion of the values of social justice, accountability, transparency and congruence which I feel strongly about. Included is an evaluation of postmodernism, systems theory and anti-oppressive theories, three theories which have best informed my practice, and how these theories were revised, modified or confirmed (O’Connor, Wilson & Setterlund 2003:217). Issues such as the influence of the medical model in welfare work and the use of principles similar to those used during the time of the stolen generation posed a challenge to my practice on placement. I have discovered my professional identity is shaped by my belief that change is possible and can occur. I have identified closely with critical social work practice and a reflective approach.

Developing culturally competent reflective practitioners. Part 2. The culturally responsive reflective practice model

Description: This paper extends the issues and arguments raised in Part 1 of this article, and outlines the dimensions of a new framework designed specifically for the introduction of reflective practice into different cultures and becoming culturally attuned as competent reflective practitioners. The framework for the development of culturally competent reflective practice draws on theories, models, and explanations of both reflective practice and culture, and benefits from the cultural experiences of the authors, which adds further authenticity to the model's development and use. This educational model can be used by educators to sensitise themselves to cultural nuances, aid students in becoming culturally responsive (aware, safe, or competent), provide a structure for class planning, and remind themselves of the need for cultural competence when introducing reflective practice within a 'different' culture. © 2008 Scientific Communications International Limited.

Description: Tennis performance is multi-faceted, characterized by an intricate integration of physical attributes, perceptual skill and technical proficiency. The dyanamics of the sport and the various styles adopted by players (e.g. baseline or serve and volley), ensures that there is no predetermined match intensity or duration. Similarly, variable environmental conditions challenge sustained performance excellence. Success at the elite is often determined by one's ability to resist fatigue.

Description: Nondeterministic conformational search techniques, such as Genetic Algorithms (GAs) are promising for solving protein structure prediction (PSP) problem. The crossover operator of a GA can underpin the formation of potential conformations by exchanging and sharing potential sub-conformations, which is promising for solving PSP. However, the usual nature of an optimum PSP conformation being compact can produce many invalid conformations (by having non-self-avoiding-walk) using crossover. While a crossover-based converging conformation suffers from limited pathways, combining it with depth-first search (DFS) can partially reveal potential pathways. DFS generates random conformations increasingly quickly with increasing length of the protein sequences compared to random-move-only-based conformation generation. Random conformations are frequently applied for maintaining diversity as well as for initialization in many GA variations.

Digital image retrieval using intermediate semantic features and multistep search

Description: Recently, semantic image retrieval has attracted large amount of interest due to the rapid growth of digital image storage. However, existing approaches have severe limitations. In this paper, a new approach to digital image retrieval using intermediate semantic features and multistep search has been proposed. Instead of looking for human level semantics which is too challenging at this stage, the research looks for heuristic information and intermediate semantic features which can describe image content objectively. Different from the conventional approaches, the intermediate features are used as filters to eliminate large amount of irrelevant images. Conventional content based image retrieval techniques and relevance feedback (RF) are applied following the filtering to improve the retrieval accuracy. The proposed system has the power of capturing both regional features and global features, and making use of both semantic features and low level features. The proposed system also uses a powerful user interface to provide users with convenient retrieval mechanisms including SQL, RF and query by example. Results show the system has a significant gain over existing region based and global image retrieval approaches

Description: This study investigated several aspects of the value and funding of diplomas and advanced diplomas in community services and health (CSH). It reviewed the extent of training at this level, various data on the employment of persons with these qualifications and the ways training is funded. A number of key questions are addressed in this paper. What is the value of diploma and advanced diploma qualifications in responding to the needs of the CSH industries? How are diplomas and advanced diplomas currently being funded? What is the best way to fund higher level qualifications within the CSH industries? Key findings include: student numbers in diplomas and advanced diplomas have been rising in CSH but declining in most other industries; employment in CSH has been rising rapidly and within CSH the proportion of persons with diplomas or advanced diplomas has been rising; the mandating of minimum qualifications for particular occupations has been an important factor in the increased employment of persons with diplomas in CSH; most of the training for diplomas is provided in government supported training, however, of the small numbers taking advanced diplomas, only a minority are in government supported places; about 13 per cent of all government recurrent expenditure on [vocational education and training] VET is made on CSH Training Package courses; and of that 13 per cent about a third is spent on training for diplomas and advanced diplomas.

Description: Global student mobility has placed pressure on western universities to recruit students from non-western, non-English-speaking backgrounds. In this article, we argue that language requirements such as the International English Language Testing System bands are underpinned by discourses that privilege western modes of thought. We go on to argue that English language proficiency underpins discourses of deficit that construct non-western students as less able to undertake research programmes. In exploring pedagogical possibilities, we draw on a published story of an international higher degree research student, called Mei, at an Australian university. We question the idea that a research higher degree is more about linguistic skills than it is about research skills, and we argue that rigour, scholarship, and new knowledge constitute the assessable factors in what international higher degree research students produce.

Description: A new derivative-free method is developed for solving unconstrained nonsmooth optimization problems. This method is based on the notion of a discrete gradient. It is demonstrated that the discrete gradients can be used to approximate subgradients of a broad class of nonsmooth functions. It is also shown that the discrete gradients can be applied to find descent directions of nonsmooth functions. The preliminary results of numerical experiments with unconstrained nonsmooth optimization problems as well as the comparison of the proposed method with the nonsmooth optimization solver DNLP from CONOPT-GAMS and the derivative-free optimization solver CONDOR are presented. © 2007 Springer Science+Business Media, LLC.
