- Description: Surface temperatures of synthetic turf have become a factor of growing interest and concern, particularly in warmer regions like Australia. However, it is unclear which components of the synthetic turf system contribute to surface temperature. The aim of this paper was to compare the surface temperature of 34 different synthetic turf products that were exposed to the same environmental conditions to ascertain which components of the synthetic turf system and which environmental factors contributed to increased surface temperature. A total of 6,120 observations were taken on the 34 products over the summer months, giving 30 observations for each of the variables on each product. An analysis of covariance (ANCOVA) indicated that the type of infill and shockpad had small-medium, but significant, effects on surface temperature (p<0.001 and p=0.003, respectively), and the interaction between shockpad and tuft gauge was also significant (p=0.047). Level of solar radiation, ambient temperature and relative humidity (p<0.001 in all instances) were the only environmental variables that significantly influenced surface temperature. These findings confirm that both the composition of the synthetic turf system and environmental factors contribute to synthetic turf surface temperature, thus providing important information for synthetic turf manufacturers developing new cool climate products, or for local government authorities selecting products and/or informing safe play for end-users.

- Description: This paper examines the influence of neutralization techniques, perceived sanction severity, perceived detection certainty and perceived benefits of using the Internet for personal purposes on intention to use the Internet at work for personal use. To do so, we draw on a conceptual framework integrating neutralization theory and general deterrence theory. The study finds that both neutralization techniques and perceived benefits have a positive effect on personal use of the Internet. Perceived detection certainty is found to have a negative effect on personal use of the Internet, while the effect of perceived sanctions severity on personal use of the Internet is not significant. The effect of neutralization and perceived benefits are much stronger than perceived detection certainty. The findings suggest that people may think more about neutralization and perceived benefits than they do about costs, when deciding whether to use the Internet at work for personal purposes.

- Description: The emotions aroused in response to the 1913 premiere of Le sacre du printemps are well recorded. The complex percussive and rhythmic elements of Igor Stravinsky’s score and their embodiment in Vaslav Nijinsky’s angular and earth-bound choreography were received by hisses and catcalls so loud the members of the orchestra could not hear one another, and nor could members of the ballet corps hear the orchestra and remain in sync. While such responses could be attributed to the shock of the new—that is, the shock of a dance that did not conform to expectations of what constitutes a traditional (romantic) balletic performance—this paper suggests that this reaction is also attributable to the ballet’s modernist aesthetic. This aesthetic created affective movements that constituted a new form of absolute dance, one that focuses on the body as the source of dramatic tension, and moves beyond ballet’s traditional representation of emotional and narrative content. We suggest that in Nijinsky’s realisation of the ballet there is an affective relationship in the movement of bodies that exceeds the representational and programmatic structure of the work as well as the assumed boundaries of the dancers’ bodies.

- Description: The Lake Pertobe wetland system is a semi-natural wetland that has been modified primarily for recreational use. However, this lake system receives stormwater from much of the central business district of Warrnambool City (Victoria, Australia) and serves as a buffer zone between the stormwater system and the Merri River and Merri Marine Sanctuary. This work considers the impact of stormwater inputs on Lake Pertobe and the effectiveness of the lake in protecting the associated marine sanctuary. Sediment contaminants (including heavy metals and polycyclic aromatic hydrocarbons (PAHs)) and water quality parameters within the lake, groundwater and stormwater system were measured. Water quality parameters were highly variable between stormwater drains and rain events. Suspended solids rapidly settled along open drains and shortly after entering the lake. Groundwater inputs increased both salinity and dissolved nitrogen in some stormwater drains. Some evidence of bioaccumulation of metals in the food chain was identified and sediment concentrations of several PAHs were very high. The lake acted as a sink for PAHs and some metals and reductions in Escherichia coli, biological oxygen demand and total phosphorus were observed, affording some protection to the associated marine sanctuary. Nutrient retention was inadequate overall and it was identified that managing the lake primarily as a recreational facility impacted on the effectiveness of stormwater treatment in the system.

- Description: There are a number of risk factors which increasingly impact the health and wellbeing of Australians, particularly in rural communities. To address the health and wellbeing of communities, local governments are taking on a more focused role by supporting healthy community initiatives (HCI). This paper presents local council partners perceptions concerning a regional-scale health promotion initiative that was undertaken in rural Tasmania, Australia. The evaluation provides insight into the future decisions and strategies that may be developed to improve processes, methods and outcomes of health initiatives undertaken by local governments. The study used a mixed methods approach collecting data through a questionnaire, focus group discussions and interviews with stakeholders and participating councils to provide an understanding of the effectiveness and success of, and barriers to, the health promotion initiative. It was found that there was an emphasis by local councils on programs that promoted physical activities, while programs that focused on healthy food and other health promotion topics, such as quit smoking and healthy workplaces were less emphasised. Overall, the health promotion initiative was perceived to be effective; however, there was little measureable evidence as to the outcomes of the various projects within the initiative and there was concern regarding the sustainability of the initiative beyond the funding timeframe. Community based, health promotion interventions are complex. Local government are suitably placed to deliver health promotion initiatives, as they have a greater understanding and can affect the greatest change by investing in projects with the highest priority among those communities within their boundaries. Nevertheless, sustainability of projects beyond funding allocation, while building and improving partnerships among local governments, and service agencies to pool resources and capture specific target groups must be central to ongoing initiatives.

- Description: Diagnostic radiology struggles to maintain high interpretation accuracy. Retrieval of past similar cases would help the inexperienced radiologist in the interpretation process. Character n-gram model has been effective in text retrieval context in languages such as Chinese where there are no clear word boundaries. We propose the use of visual character n-gram model for representation of image for classification and retrieval purposes. Regions of interests in mammographic images are represented with the character n-gram features. These features are then used as input to back-propagation neural network for classification of regions into normal and abnormal categories. Experiments on miniMIAS database show that character n-gram features are useful in classifying the regions into normal and abnormal categories. Promising classification accuracies are observed (83.33%) for fatty background tissue warranting further investigation. We argue that Classifying regions of interests would reduce the number of comparisons necessary for finding similar images from the database and hence would reduce the time required for retrieval of past similar cases.

Walking the trade route to a dead end? Exploring journey stories of early completers of Victorian School Vocational Programs

- Description: In Victoria, there are some school students who, having completed Year 11, as Victorian Certificate of Applied Learning (VCAL) Intermediate students, leave school. They do not go on to complete Year 12 [or equivalent] either in other institutions or as part of an apprenticeship or traineeship. This group of students is quite a substantial proportion of the total VCAL student cohort, and their numbers are increasing every year. This behaviour is juxtaposed with government policy that is emphasizing youth participation in schools or vocational alternatives. The Compact with Young Australians (COAG, 2009) set a new target of 90% attainment of Year 12 or equivalent by 2015 and expects an additional 92,527 young people across Australia (23,500 in Victoria) to remain in school. A survey of the literature indicates that there is a significant gap in our knowledge of what behavioural intentions drive vocational students to leave school early. By using in-depth conversations with selected students, this study seeks to determine the factors that students see act as drivers in their decision to get to this level, and then to leave school. This study provides, in the words of the students, some of the reasons for their choice for their non-continuance of the secondary school programs that are available to them. This will enable education policy makers to understand these students’ perspectives and to examine the VCAL programs in a new light. As educators, they can then respond to the challenge to develop and sustain vocational programs and retention strategies that will engage young people and assist them to build work-ready skills.

- Description: Background: Players are the targeted end-users and beneficiaries of exercise-training programmes implemented during coach-led training sessions, and the success of programmes depends upon their active participation. Two variants of an exercise-training programme were incorporated into the regular training schedules of 40 community Australian Football teams, over two seasons. One variant replicated common training practices, while the second was an evidence-based programme to alter biomechanical and neuromuscular factors related to risk of knee injuries. This paper describes the structure of the implemented programmes and compares players’ end-of-season views about the programme variants. Methods: This study was nested within a larger group-clustered randomised controlled trial of the effectiveness of two exercise-training programmes (control and neuromuscular control (NMC)) for preventing knee injuries. A post-season self-report survey, derived from Health Belief Model constructs, included questions to obtain players’ views about the benefits and physical challenges of the programme in which they participated. Results: Compared with control players, those who participated in the NMC programme found it to be less physically challenging but more enjoyable and potentially of more benefit. Suggestions from players about potential improvements to the training programme and its future implementation included reducing duration, increasing range of drills/exercises and promoting its injury prevention and other benefits to players. Conclusions: Players provide valuable feedback about the content and focus of implemented exercise-training programmes, that will directly inform the delivery of similar, or more successful, programmes in the future.

- Description: Objectives: To obtain benefits from sports injury prevention programs, players are instructed to perform the exercises as prescribed. We developed an observational checklist to measure the quality of exercise performance by players participating in FootyFirst, a coach-led, exercise-based, lower-limb injury prevention program in community Australian Football (AF). Design: Observational. Methods: The essential performance criteria for each FootyFirst exercise were described in terms of the technique, volume and intensity required to perform each exercise. An observational checklist was developed to evaluate each criterion through direct visual observation of players at training. The checklist was trialled by two independent raters who observed the same 70 players completing the exercises at eight clubs. Agreement between observers was assessed by Kappa-statistics. Exercise fidelity was defined as the proportion of observed players who performed all aspects of their exercises correctly. Results: The raters agreed on 61/70 observations (87%) (Kappa = 0.72, 95% CI: 0.55; 0.89). Of the observations with agreed ratings, 41 (67%) players were judged as performing the exercises as prescribed. Conclusions: The observational checklist demonstrated high inter-rater reliability. Many players observed did not perform the exercises as prescribed, raising concern as to whether they would be receiving anticipated program benefits. Where quality of exercise performance is important, evaluation and reporting of program fidelity should include direct observations of participants.

- Description: Nursing texts laud the role of nurses as advocates for patients. With increased acknowledgement of patient-centred care, is it appropriate or desired for nurses to presume this as their role? An examination of concepts of advocacy and autonomy highlight potential conflicts between the nurses' adoption of the roles of advocate and surveyor in renal care. There is no clear and definitive answer to 'who can speak for whom' when considering advocacy for people involved in renal replacement therapies. It is evident that what is required is clearer articulation of how renal nurses can act as advocates for patients within the context of their multiple roles and with a goal of partnerships in care.

An examination of concepts of advocacy and autonomy highlight potential conflicts between the nurses' adoption of the roles of advocate and surveyor in renal care. There is no clear and definitive answer to 'who can speak for whom' when considering advocacy for people involved in renal replacement therapies. It is evident that what is required is clearer articulation of how renal nurses can act as advocates for patients within the context of their multiple roles and with a goal of partnerships in care.
Why firms in China go green and how they market green?

- Description: Since the late 1970s China has strived to build a globally competitive market economy based on a range of industry sectors, focusing on manufacturing and allied industries. By 2014 the size of China’s economy is second only to that of the United States of America. A challenge in this context and situation—where economic growth is still a key area of policy focus for the government—is dealing with associated environmental matters and issues. By the turn of the 21st Century, environmental issues were receiving an unprecedented degree of attention from the Chinese Government, and one of the subsets of this issue is the concept of green marketing. A question arises regarding the possibilities of successful growing firms in China applying the concepts, principles and practices which embody green marketing within a rubric and context of sustained economic development. To gain a deep understanding of ways in which the concepts, applications and conditions of green marketing actually work in China, this research explores why firms in China go green and how they market their green products and services in China using an emic approach that emphasizes an indigenous, within culture perspective of firms’ behaviour in the Chinese context. Related to the research question this research explores a range of possible motivating factors and ascertains features of key influential stakeholders which might well influence firms’ green marketing approaches and practices in China. These firms are exceptional in the way they have addressed green marketing. The research undertaken seeks to identify ways in which these factors translate in marketing terms within a green marketing paradigm. Given that green marketing is arguably where economic development and environmental matters tend to interact and intersect within a market economy, this research provides insights to how sustainable Chinese firms deal with this complex and important issue. The use of a case study approach, across a range of industry sectors and in a variety of locations in China, provides depth and realism to this research. The result of this research contribute significantly to the understanding of how Chinese managers perceive ecological sustainability and expand firm stakeholder theory by identifying key influential stakeholders in proactive green decisions. The ways in which firms define and identify key influential stakeholders in their green decisions are influenced by resource dependency, the institutional power of the stakeholders, and moderated by firm’s characteristics and life cycle stages. Firms operating in a strong government-driven setting derive four conceptual green motivations—philosophical and social responsibility, management of risk reduction, competition pressure, and special events— that offer insights on understanding firms’ green behaviours and green orientations in China.

- Description: Objectives: This study investigates (i) maternity care access issues in rural Tasmania, (ii) rural women's challenges in accessing maternity services and (iii) rural women's access needs in maternity services. Methods: A mixed-method approach using a survey and semi-structured interviews was conducted. The survey explored women's views of rural maternity services from antenatal to postnatal care, while interviews reinforced the survey results and provided insights into the access issues and needs of women in maternity care. Findings: The survey was completed by n=210 women, with a response rate of 35%, with n=22 follow-up interviews being conducted. The survey indicated the majority of rural women believed antenatal education and check-ups and postnatal check-ups should be provided locally. The majority of women surveyed also believed in the importance of having a maternity unit in the local hospital, which was further iterated and clarified within the interviews. Three main themes emerged from the interview data, namely (i) lack of access to maternity services, (ii) difficulties in accessing maternity services, and (iii) rural women's access needs. Conclusion: The study suggested that women's access needs are not fully met in some rural areas of Tasmania. Rural women face many challenges when accessing maternity services, including financial burden and risk of labouring en route. The study supports the claim that the closure of rural maternity units shifts cost and risk from the health care system to rural women and their families. © 2013 Australian College of Midwives.

- Description: Young people transitioning from out-of-home care are known to have poor educational outcomes compared to their non-care peers. Yet little is known about the experiences or needs of the small numbers of Australian care leavers who enter higher education. This article critically examines existing Australian and international research on the access of care leavers to higher education. A group of pre-care, in-care, transition from care and post-care factors are identified as either hindering or assisting care leavers to maximise their educational opportunities. Some specific policy and practice reforms are recommended to enhance opportunities for Australian care leavers to participate in and complete higher education.

'The sweet use of London': the careers abroad of Louise Mack and Arthur Maquarie

- Description: This paper examines the careers of two Australian writers who left Sydney for London at the end of the nineteenth century to explore questions of cultural, as well as literary, identity and affiliation. Louise Mack, as a poet, novelist, writer of romances, journalist and war correspondent, combined a fluid sense of national identity with a flexibility in writing across genres and readerships that makes her hard to categorise. Arthur Maquarie’s career as an Australian poet aspiring to fit into an essentially ‘English’ cultural niche provides a model of Anglo-Australianness that appears to fit a conservative model, called somewhat imprecisely from an Australian perspective, expatration - but which nonetheless retains layers of identity and experience which made complete assimilation virtually impossible. At a time when there was no clear or inevitable choice between being British or Australian, it is apparent that these writers never fully renounced (indeed, could not completely lose) either their British heritage or their colonial identity, whether working in commercial or literary milieux. Living and working in London, they were not simply expatriates or exiles, but carriers of complex and often shifting roles and identities that insisted on hybridity. Despite this theoretical hybridity being inevitable to some extent, it is still possible to distinguish between them. The colonial transnational writer’s position is differently inflected from the expatriate’s, as it entails the carrying of several layers of identity without an ideologically driven impulse to assert, renounce or choose between them. By comparison with Maquarie, Louise Mack appears to be far less troubled by notions of cultural identity, whether political or more broadly literary. Her greater mobility between genres, and her lack of any fixed status or position in social or institutional settings of the kind that Maquarie adhered to, correspond to a greater flexibility in her cultural affiliations, and produced a more fluid form of ‘colonial transnational’ identity.

A 3D approach to first year English education

- Description: Purpose: The purpose of this paper is to explore the suggestive possibilities of an approach to undergraduate English teacher education that the author has called the 3D Approach - Develop professional knowledge, Display professional knowledge, Disseminate professional knowledge - in relation to a number of groups of first year pre-service teachers (PSTs) engaging the teaching and learning materials of their English education course. Design/methodology/approach: The paper examines ways in which this approach has been assessed by the PSTs themselves, constructing this as an expression of their lived experience as PSTs. The author draws on Vygotsky's concept of the Zone of Proximal Development, initiates a systematic and orchestrated program of explicit scaffolding of first year PST learning and draws on University-generated student assessment of their courses, focus groups and individual interviews to investigate ways in which the 3D approach may be considered as enhancing first year PST learning. Findings: PSTs' own informed evaluations of their own developing knowledge have made visible the teaching and learning that they have engaged and articulated. What the author outlines in this paper is not a "Eureka" moment for first year PSTs, but it is the result of careful scholarly considerations of what careful scholarly considerations by first years in Education courses may engage. For this cohort of PSTs, and for the author, it is a particular form of engagement with pedagogy. It is a pedagogy for teachers, part of active engagement on the part of the teacher and the learner, producing knowledge together. Research limitations/implications: Lack of generalisability from case study research may be considered as a limitation, but the author would argue that it is the details thrown up for careful examination in a case study which may serve to inform professional discussion and debate. Practical implications: Negative press of inadequate teachers emerging from universities, with their specious claims will not progress reasoned discussion; research on how the PSTs are themselves taught and how they develop as professionals will. PSTs' own informed evaluations of their own developing knowledge will go some way towards enabling this to happen. This sort of research opens up possibilities for starting with the right sort of questions, a shift from asking the wrong sort of questions, which the author would argue is that sort on which the media are basing their opinion pieces. Social implications: Continuing public discussions, usually conducted in and by the media, about teacher quality, particularly as this tends to be tied to notions of teacher pay, indicates a wider social concern about the need for quality teachers. This sort of social concern is also a major concern for teacher educators, and is to be addressed as such. This paper addresses some of those concerns. Originality/value: The paper engages issues about teacher education raised publicly in the media and ties these to the more private domain of university practice in a given teacher education course. © Emerald Group Publishing Limited.

- Description: In blasting operation, the aim is to achieve proper fragmentation and to avoid undesirable events such as backbreak. Therefore, predicting rock fragmentation and backbreak is very important to arrive at a technically and economically successful outcome. Since many parameters affect the blasting results in a complicated mechanism, employment of robust methods such as artificial neural network may be very useful. In this regard, this paper attends to simultaneous prediction of rock fragmentation and backbreak in the blasting operation of Tehran Cement Company limestone mines in Iran. Back propagation neural network (BPNN) and radial basis function neural network (RBFNN) are adopted for the simulation. Also, regression analysis is performed between independent and dependent variables. For the BPNN modeling, a network with architecture 6-10-2 is found to be optimum whereas for the RBFNN, architecture 6-36-2 with spread factor of 0.79 provides maximum prediction aptitude. Performance comparison of the developed models is fulfilled using value account for (VAF), root mean square error (RMSE), determination coefficient (R2) and maximum relative error (MRE). As such, it is observed that the BPNN model is the most preferable model providing maximum accuracy and minimum error. Also, sensitivity analysis shows that inputs burden and stemming are the most effective parameters on the outputs fragmentation and backbreak, respectively. On the other hand, for both of the outputs, specific charge is the least effective parameter. © 2013 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences.

This paper argues the reform in scientific Chinese trinity with an emphasis of the word "scientific" ought to play a key role for further Chinese economic development and to launch a much improved contemporary Chinese society on a solid foundation. In addition, this paper proposes specifically ten computing paradigms and examines critically their potential impacts on scientific Chinese trinity. Finally, we feel the very focused approaches as proposed here might inspire as well as provide a much needed road map toward the goal of the scientific Chinese trinity. Judiciously chosen vigorous research projects appear to be indispensable.

A conceptual model of physical performance in Australian Football
- Authors: Mooney, Mitchell
- Date: 2013
- Type: Text , Thesis , PhD
- Full Text:
- Description: Objective: The objective of this project was to identify the relative influence of valid physical parameters to elite Australian Football performance. Methods: Data was collected on match performance variables (i.e. coaches’ votes, number of ball disposals, champion data rank), match exercise intensity measures (m∙min-1, m∙min-1 above and below 15 km∙h-1 and Load™∙min-1) and physical capacities (yo-yo intermittent recovery test level 2, maximum oxygen uptake, running economy, relative aerobic intensity, maximal aerobic speed and maximal accumulated oxygen deficit) on elite and recreational Australian footballers. These variables were modelled to determine the logical sequence and relative importance towards match performance. Results: The results indicate a sequential physical path to Australian Football performance. The yo-yo intermittent recovery test (level 2) performance influenced match exercise intensity (m∙min-1 >15 km∙h-1& Load™∙min-1) which in turn, affected Australian Football performance (number of ball disposals and coaches’ votes). This sequence was altered by experience, playing position and neuromuscular fatigue. The number of interchange rotations also influenced match exercise intensity throughout the match. Furthermore, the yo-yo intermittent recovery test (level 2) was found to be determined by a complex interaction of physical capacities. However, yo-yo intermittent recovery (level 2) performance was most influenced by maximum oxygen uptake, relative aerobic intensity and maximum aerobic speed. Conclusion: This dissertation showed Australian Football performance is a complex and dynamic system influenced by many variables interacting with each other in a sequential path. Sports scientists and coaches may utilise this information as a framework to evaluate Australian Football performance matches.
