Cholecystokinin and leptin: their influence upon the eating behaviour and nutrient intake of dialysis patients

Background We have used serial visual analogue scores to demonstrate disturbances of the appetite profile in dialysis patients. This is potentially important as dialysis patients are prone to malnutrition yet have a lower nutrient intake than controls. Appetite disturbance may be influenced by accumulation of appetite inhibitors such as leptin and cholecystokinin (CCK) in dialysis patients. Methods Fasting blood samples were drawn from 43 controls, 50 haemodialysis (HD) and 39 peritoneal dialysis (PD) patients to measure leptin and CCK. Hunger and fullness scores were derived from profiles compiled using hourly visual analogue scores. Nutrient intake was derived from 3 day dietary records. Results Fasting CCK was elevated for PD (6.73 ± 4.42 ng/l vs control 4.99 ± 2.23 ng/l, P < 0.05; vs HD 4.43 ± 2.15 ng/l, P < 0.01). Fasting CCK correlated with the variability of the hunger (r = 0.426, P = 0.01) and fullness (r = 0.52, P = 0.002) scores for PD. There was a notable relationship with the increase in fullness after lunch for PD (r = 0.455, P = 0.006). When well nourished PD patients were compared with their malnourished counterparts, CCK was higher in the malnourished group (P = 0.004). Leptin levels were higher for the dialysis patients than controls (HD and PD, P < 0.001) with pronounced hyperleptinaemia evident in some PD patients. Control leptin levels demonstrated correlation with fullness scores (e.g. peak fullness, r = 0.45, P = 0.007) but the dialysis patients did not. PD nutrient intake (energy and protein intake, r = -0.56, P < 0.0001) demonstrated significant negative correlation with leptin. Conclusion Increased CCK levels appear to influence fullness and hunger perception in PD patients and thus may contribute to malnutrition. Leptin does not appear to affect perceived appetite in dialysis patients but it may influence nutrient intake in PD patients via central feeding centres.

GCAP 2010 presentation : jams, jellybeans and the fruits of passion

In 2010 we realised that our fifth 48 hour game making competition was more than a mere event but that we were actually watching our local games industry enact a very intense process of community making and reflective practice. This presentation of our early research on the event was an invited spectacle at the Games Connect Australia Pacific Conference 2010 held at the Gold Coast Convention Centre, 14-15 October 2010. Abstract: Jams, Jellybeans and the fruit of passion: if games are about creating innovative player experience, then the place to start is how we set up game design education as an experience Authors: truna aka j.turner – Brisbane IGDA & Lubi Thomas, Mt Nebo Studios The 48 hour game making challenge has grown since it started in 2007 to accommodate 20 teams, some of the teams are professionals, some are made of people who are working in other industries, most are made of students from the various tertiary institutes around town. We still don’t quite understand why these mad people sign up for 48 hours of intense creativity just for the jelly beans we hand out as prizes but we do suspect that the space we give them and the passion they bring to the event offers those of us involved in the education side of the games industry really vital insights into what is critical and important in terms of education. The Australian games industry really needs these people, they are bright and ingenious and they make the most amazing games. But you won't get them by telling tertiary institutions what you fancy this year in terms of skills and criteria; you will get them by fostering their creativity and passion. If games are about creating innovative player experience, then the place to start is how we set up game design education as an experience.

The Fifth 48 Hour Game Making Challenge (2011)

The 48-hour game making challenge started out in 2007 as a creative community event. We have run this event each year since and seen over 120 games made. 2011 was the most remarkable in that each of the 20 teams made a playable game – the shape of the challenge has changed …. We have invested in the process of reflective practice & action research, with the event being part of a sweep of programs that inform this research, with each year giving us fresh insights into both the creative practice and essential concerns, process and trends of the independent games industry creative community, which we then respond to within our curatorial development of the subsequent programming. The 2011 48-hour challenge research project focused on the people and the site. We were specifically interested in the manner in which the community occupied the creative space.

Visualising the 48 hour game making challenge

We have always felt that “something very special” was happening in the 48hr and other similar game jams. This “something” is more than the intensity and challenge of the experience, although this certainly has appeal for the participants. We had an intuition that these intense 48 hour game jams exposed something pertinent to the changing shape of the Australian games industry where we see the demise of the late 20th century large studio - the “Night Elf” model and the growth of the small independent model. There are a large number of wider economic and cultural factors around this evolution but our interest is specifically in the change from “industry” to “creative industry” and the growth of games as a cultural media and art practice. If we are correct in our intuition, then illuminating this something also has important ramifications for those courses which teach game and interaction design and development. Rather than undertake a formal ethno-methodological approach, we decided to track as many of the actors in the event as possible. We documented the experience (Keith Novak’s beautiful B&W photography), the individual and their technology (IOGraph mouse tracking), the teams as a group (Time lapse photography) and movement tracking throughout the whole space (Blue tooth phone tracking). The raw data collected has given us opportunity to start a commentary on the “something special” happening in the 48hr.

The asthmatic athlete, inhaled beta agonists, and performance

INTRODUCTION: The large increase in the number of athletes who apply to use inhaled beta agonists (IBAs) at the Olympic Games is a concern to the medical community. This review will examine the use of IBAs in the asthmatic athlete, the variability that exists between countries and sport, and outline a plan to justify the use of these medications. DATA SOURCES: Much of this article is a result of an International Olympic Committee (IOC) Medical Commission-sponsored meeting that took place in May 2001. Records of the use of IBAs at previous Olympics were reviewed. MEDLINE Searches (PubMed interface) were performed using key words to locate published work relating to asthma, elite athletes, performance, treatment, and ergogenic aids. MAIN RESULTS: Since 1984 there have been significant increases in the use of IBAs at the Olympic Games as well as marked geographical differences in the percentage of athletes requesting the use of IBAs. There are large differences in the incidence of IBA use between sports with a trend towards increased use in endurance sports. There are no ergogenic effects of any IOC-approved IBA given in a therapeutic dose. CONCLUSIONS: In many cases, the prescription of IBAs to this population has been made on empirical grounds. Beginning with the 2002 Winter Games, athletes will be required to submit to the IOC Medical Commission clinical and laboratory evidence that justifies the use of this medication. The eucapnic voluntary hyperpnea test will be used to assess individuals who have not satisfied an independent medical panel of the need to use an IBA.

Performing design: game design, practice, praxis and the theatre of the impressed

This paper is a reflection on a design teaching project that endeavours to establish a culture of critical design thinking in a tertiary game design course. In the first instance, the ‘performing design’ project arose as a response to contemporary issues and tensions in the Australian games industry and game design education, in essence, the problem of how to scaffold undergraduate students from their entry point as ‘players’ (the impressed) into becoming designers. The performing design project therefore started as a small-scale intervention to inspire reflection in a wider debate that includes: the potential evolution of the contemporary games industry; the purpose of game design education; and the positioning of game design as a design discipline. Our position is that designing interactive playful works or games is victim of a tendency to simplify the discipline and view it from either the perspective of science or art. In this paper we look at some of the historical discussions on the distinct identity of games. Then we present an overview of the typical state of play in contemporary game design education which inspires the performing design project as an intervention or teaching technique. This leads us to question understandings of education and training and creativity and innovation. Finally we reflect on insights arising from the performing design project which lead us to support Archer’s call for a ‘third area’ that balances the monolithic practices of the two major academic disciplines.

Inside the pleasure dome : cultural tourism on Australia’s Gold Coast

The City of the Gold Coast in Queensland, Australia, will host the Commonwealth Games in 2018. In advance of the Games, the City is beginning to reposition the traditional marketing programs that were based around the four S’s- ‘sun, sand, surf and sex.’ There is a new emphasis on urban sophistication, sport, science, education and the environment. At the same time, local communities are asking for renewed attention to residential issues, particularly relating to recognising the importance of culture to the region. In this paper I explore the development of integrated computer technologies (ICTs) as a way of linking tourism, culture and place in the experience economy of the Gold Coast. The discussion is framed by theories of the post-tourist, contemporary cultural tourism and the role of mobile technologies, and the figure of the ‘referential tourist.’ An examination of stakeholder responses to changing business and social frameworks on the Gold Coast shows how discussions about a range of issues coalesce around cultural tourism. Local communities have the opportunity to engage with the new tourist as they move quickly between leisure and cultural experiences, at once connected to tourist expectations but increasingly self-directed. The Surfers Paradise Nights campaign, which is based around social media, is a case in point. This campaign aims to interest visitors in becoming a part of a familiar third place, an online space, but one that will sustain an emotive connection to the physical location and events. The paper also draws on research carried out in Brisbane, Queensland, in relation to building connections between place and culture on designated, self-directed journeys via iPhone technology. Participant responses indicate the importance of narrative to developing cultural frameworks.

GO423 - the second Game On / brIGDA Independant Game Symposium

GO423 was initiated in 2012 as part of a community effort to ensure the vitality of the Queensland Games Sector. In common with other industrialised nations, the game industry in Australia is a reasonably significant contributor to Gross National Product (GNP). Games are played in 92% of Australian homes and the average adult player has been playing them for at least twelve years with 26% playing for more than thirty years (Brand, 2011). Like the games and interactive entertainment industries in other countries, the Australian industry has its roots in the small team model of the 1980s. So, for example, Beam Software, which was established in Melbourne in 1980, was started by two people and Krome Studios was started in 1999 by three. Both these companies grew to employing over 100 people in their heydays (considered large by Antipodean standards), not by producing their own intellectual property (IP) but by content generation for off shore parent companies. Thus our bigger companies grew on a model of service provision and tended not to generate their own IP (Darchen, 2012). There are some no-table exceptions where IP has originated locally and been ac-quired by international companies but in the case of some of the works of which we are most proud, the Australian company took on the role of “Night Elf” – a convenience due to affordances of the time zone which allowed our companies to work while the parent companies slept in a different time zone. In the post GFC climate, the strong Australian dollar and the vulnerability of such service provision means that job security is virtually non-existent with employees invariably being on short-term contracts. These issues are exacerbated by the decline of middle-ground games (those which fall between the triple-A titles and the smaller games often produced for a casual audience). The response to this state of affairs has been the change in the Australian games industry to new recognition of its identity as a wider cultural sector and the rise (or return) of an increasing number of small independent game development companies. ’In-dies’ consist of small teams, often making games for mobile and casual platforms, that depend on producing at least one if not two games a year and who often explore more radical definitions of games as designed cultural objects. The need for innovation and creativity in the Australian context is seen as a vital aspect of the current changing scene where we see the emphasis on the large studio production model give way to an emerging cultural sector model where small independent teams are engaged in shorter design and production schedules driven by digital distribution. In terms of Quality of Life (QoL) this new digital distribution brings with it the danger of 'digital isolation' - a studio can work from home and deliver from home. Community events thus become increasingly important. The GO423 Symposium is a response to these perceived needs and the event is based on the understanding that our new small creative teams depend on the local community of practice in no small way. GO423 thus offers local industry participants the opportunity to talk to each other about their work, to talk to potential new members about their work and to show off their work in a small intimate situation, encouraging both feedback and support.

Stories into games (Workshops and digital work)

In the summer of 2012 - 2013, the State Library of Queensland invited us to run a number of workshops for younger participants as part of the Garage Gamer program. The brief was very much about the local games industry and the SLQ community, the core concept was about participant contribution. The 'Stories into Games' series of workshops ran across three Saturdays (January 5 - March 2). The workshops were aimed at younger audiences (ages 6-12) and the concept was to engage this group with games as game makers and designers, rather than players. Each session saw a group of participants create a shared story, illustrate the story and then make game assets and objects out of their illustrative work. These were then put into a raw framework created in the Unity Game Engine so that the stories could be played.

Variations in acculturation and Australian physical education teacher education students' receptiveness to an alternative pedagogical approach to games teaching

Background The development of intelligent, thinking performers as a central theme in Physical Education curriculum documents worldwide has highlighted the need for an evolution of teaching styles from the dominant reproductive approach. This has prompted an Australian university to change the content and delivery of a games unit within their Physical Education Teacher Education (PETE) course and adopt a productive student centred approach that is compatible with current curriculum directives. The significance of prospective physical educators’ biographies on their receptiveness to this pedagogical innovation was studied to help recognise and understand potential differences and subsequently guide programme development to help improve the impact of teacher education. Purpose To investigate whether past school and sporting experiences are powerful influences on Australian PETE recruits’ initial perspectives about effective physical education teaching practice and their receptiveness to an alternative pedagogical approach. Participants and Setting 49 first year pre-service PETE students (53% male; 47% female; mean age 18.88 ± 1.57 years) undertaking a compulsory unit on games teaching at an Australian university volunteered to take part in the study and were grouped according to their highest level of representation in games, either school/club (n=13), regional (n=20), or state/national (n=16). Students experienced the constraints-led approach as learners and teachers during an 8-week games unit informed by nonlinear pedagogy and underpinned by motor learning theory. Data collection and Analysis Prior to the commencement of the unit participants completed part A of a two part mixed response questionnaire aimed at gathering data about their physical education and sporting background. The data were summarised using descriptive statistics. Pre and post intervention, participants completed part B responding, via Likert Scale with their opinion of the importance of each sub-component of the traditional reproductive style for an effective games teaching session. This resulted in a traditional reproductive games teaching belief score. For each sub-component, participants were invited to respond in more detail to justify their opinions. A one-way between groups analysis of variance (ANOVA), Tukey’s HSD Post Hoc Test and a two - tailed, paired samples t test were used to analyse the quantitative data. Content analysis was used to analyse the qualitative data. Findings The traditional, reproductive approach was the most frequently reported teaching approach used by the physical education teachers and sports coaches of participants in all groups. Prior to the commencement of the alternate games unit, participants in each representative level group held very strong custodial traditional reproductive games teaching beliefs. After experiencing the alternative games unit there were statistically significant differences in the traditional reproductive games teaching belief mean scores for each group, This combined with participants’ qualitative responses indicated a receptiveness to the alternative pedagogy. Conclusions The results of this present study show that, contrary to previous research undertaken in North America, in Australia, it is possible for PETE educators to change beliefs in order to overcome the constraint of acculturation and provide PETE students with the knowledge, understanding and belief in an alternate approach to teaching games in physical education compatible with curriculum documents.

The Australian Nonprofit Sector Legal and Accounting Almanac 2013

INTRODUCTION CASES For a number of years, Professor Myles McGregor-Lowndes, Frances Hannah and Anne Overell have compiled one to two page summaries of cases involving nonprofit organisations and published them on The Australian Centre for Philanthropy and Nonprofit Studies, Developing Your Organisation (DYO) website.1 You can be alerted of new case summaries as they are posted to the DYO website by subscribing to the ACPNS RSS feed or the ACPNS twitter service.2 There were some very significant cases during 2013, such as Commissioner of Taxation v Cancer & Bowel Research Association (see case notes 2.8.2 and 2.8.11), The Hunger Project case which is under appeal, but could change the face of PBI jurisprudence (see case note 2.8.7) while Home Health Pty Ltd retained the PBI status quo but might have been different if appealed (see case note 2.8.8). For sheer interest there is nothing better in my 30 odd years of reading tax and charity judgements than case involving The Study and Prevention of Psychological Diseases Foundation Incorporated (see case note 2.1.1). It even rivals some of the more bizarre cases from the US jurisdiction of which St Joseph Abbey v Castille (case note 2.10.9) is certainly ‘dead centre’. A set of cases which stand out for attention are those involving New Zealand’s Christchurch Cathedral which anyone with responsibility for heritage-listed buildings should study carefully, for implications in relation to their own circumstances. A number of cases summarised in this Almanac are working their way through the appeals process and care should be taken with their application. In addition, some of the cases are from jurisdictions outside Australia, and readers should exercise caution when considering the implications of these cases for Australian law. LEGISLATION The Almanac includes a review of major statutory amendments during 2013, which are relevant to the nonprofit sector in all Australian jurisdictions. Special thanks must go to Nathan MacDonald and the JusticeConnect team for providing legislative updates for Victoria. SPECIAL ISSUES DURING 2013 A number of legal practitioners have contributed articles on significant legal issues facing nonprofit organisations: charitable trusts giving to government entities (Alice Macdougall); workplace bullying (Tim Longwill); and privacy (James Tan and Nina Brewer). WORLD ROUND-UP Major developments from the UK and Ireland (Kerry O’Halloran), Canada (Peter Broder), New Zealand (Michael Gousmett and Susan Barker) and Jamaica (Frances Hannah) are all summarised in a review of a significant part of the common law charity jurisdictions. WHAT DOES 2014 HOLD The final section moves from looking in the rear view mirror to peering out the front windscreen to discern the reform agenda. The view from the windscreen in 2013 was of considerable reform traffic at the Commonwealth level jostling for a place in the parliamentary agenda. This year is quite different with a smaller number of vehicles ahead, but the potential for significant impact.

Overcoming acculturation: Physical education recruits' experiences of an alternative pedagogical approach to games teaching

Background Physical education teacher education (PETE) programmes have been identified as a critical platform to encourage the exploration of alternative teaching approaches by pre-service teachers. However, the socio-cultural constraint of acculturation or past physical education and sporting experiences results in the maintenance of the status quo of a teacher-driven, reproductive paradigm. Previous studies have reported successfully overcoming the powerful influence of acculturation, resulting in a change in PETE students’ custodial teaching beliefs and receptiveness to alternative teaching approaches. However, to date, limited information has been reported about how PETE students’ acculturation shaped their receptiveness to an alternative teaching approach. This is particularly the case for PETE recruits identified in the literature as most resistant to change. Purpose To explore the features and experiences of an alternative games teaching approach that appealed to PETE recruits’ identified as most resistant to change, requiring a specific sample of PETE recruits with strong, custodial, traditional physical education teaching beliefs, and whom are high achieving sporting products of this traditional culture. The alternative teaching approach explored in this study is the constraints-led approach (CLA), which is similar operationally to TGfU, but distinguished by a neurobiological theoretical framework (nonlinear pedagogy) that informs learning design. Participants and Setting A purposive sample of 10 Australian PETE students was recruited for the study. All participants initially had strong, custodial, traditional physical education teaching beliefs, and were successful sporting products of this teaching approach. After experiencing the CLA as learners during a games unit, participants demonstrated receptiveness to the alternative pedagogy. Data Collection and Analysis Semi-structured interviews and written reflections were sources of data collection. Each participant was interviewed separately, once prior to participation in the games unit to explore their positive physical education experiences, and then again after participation to explore the specific games unit learning experiences that influenced their receptiveness to the alternative pedagogy. Participants completed written reflections about their personal experiences after selected practical sessions. Data were qualitatively analysed using grounded theory. Findings: Thorough examination of the data resulted in establishment of two prominent themes related to the appeal of the CLA for the participants: (i) psychomotor (effective in developing skill), and (ii), inclusivity (included students of varying skill level). The efficacy of the CLA in skill development was clearly an important mediator of receptiveness for highly successful products of a traditional culture. This significant finding could be explained by three key factors: the acculturation of the participants, the motor learning theory underpinning the alternative pedagogy and the unit learning design and delivery. The inclusive nature of the CLA provided a solution to the problem of exclusion, which also made the approach attractive to participants. Conclusion PETE educators could consider these findings when introducing an alternative pedagogy aimed at challenging PETE recruits’ custodial, traditional teaching beliefs. To mediate receptiveness, it is important that the learning theory underpinning the alternative approach is operationalised in a research-informed pedagogical learning design that facilitates students’ perceptions of the effectiveness of the approach through experiencing and or observing it working.

Australia and the Scottish independence referendum

This essay examines how, given the close historical and cul-tural ties which exist between Australia and the United Kingdom (including Scotland), the Scottish independence referendum was reported, analysed and made sense of in the Australian media. The analysis is based on mainstream news coverage (online and print media) produced in Australia and accessed from the internet between January 2012 and the end of September 2014 (two weeks after the referendum on September 18). A total of 95 items were included in the sample, which does not include broadcast news coverage or specialist current affairs periodicals. The online sites of broadcasters such as the ABC and SBS were included in the sam-ple. The great majority of these items were published in the run-up to polling day, in August and September 2014, with spikes in the frequency of item around particular events such as the Commonwealth Games in Glasgow. to the fore will be relevant for years to come.

48 hour game making challenge

The 48 hour game making challenge has been running since its inception at the NEXT LEVEL Festival in 2004. It is curated by Truna aka j. Turner and Lubi Thomas and sees teams of both future game makers and industry professionals going head to head under pressure to produce playable games within the time period. The 48 hour is supported by the International Game Developers Association (Brisbane Chapter)and the Creative Industries Precincts as part of their public programs. It is a curated event which engages industry with Brisbane educational institutes and which fosters the Australian Games Industry

Learning spatial concepts from RatSLAM representations

RatSLAM is a biologically-inspired visual SLAM and navigation system that has been shown to be effective indoors and outdoors on real robots. The spatial representation at the core of RatSLAM, the experience map, forms in a distributed fashion as the robot learns the environment. The activity in RatSLAM’s experience map possesses some geometric properties, but still does not represent the world in a human readable form. A new system, dubbed RatChat, has been introduced to enable meaningful communication with the robot. The intention is to use the “language games” paradigm to build spatial concepts that can be used as the basis for communication. This paper describes the first step in the language game experiments, showing the potential for meaningful categorization of the spatial representations in RatSLAM.
