Surfing the crime net : policing, crime prevention and community safety in Australia

There can be no doubt that the Internet offers the possibility of increasing access to a range of sources of available information in a timely manner. This is particularly so as we increasingly seek to engage with information from outside our jurisdictional boundaries. While this hints at the effects of globalisation, it is also meant to be suggestive of the practical realities involved in researching (or simply following) developments occurring within emergent federal structures (for instance the European Union) or longer-standing federations such as the United States and Australia. Of course, a department or agency having a homepage and various links is only the start of the process of making information accessible. As will be indicated below, there remain significant limitations in the electronic material available from many agencies. Fortunately, there are also a number of organisations that enable the researcher to access original data and research publications.

Extreme surfing : personal and psychological aspects of big wave riders

This qualitative study investigated personal and psychological aspects of big wave riders. A cross-sectional design with non probability purposive sampling was used to gain personal interviews with 32 elite surfers who regularly ride big, life threatening waves. Each athlete was asked three open questions: 1. What do you think are the most important qualities and attributes a surfer needs for riding big waves? 2. What type of mindset is best for riding big waves?, and 3.What motivates you to ride big waves? Content analysis of the taped interview transcripts revealed seven key qualities and attributes including having a thrill seeking, confident and goal oriented personality, a high level of mental strength and control, and an intimate relationship with the ocean. The best mindset included an individually defined arousal level, a committed attitude, and a simple, yet highly aware, focus. Motivations were primarily intrinsic, though drives indicative of a behavioral addiction to the act of riding big waves also emerged. Evidence of common developmental stages for riding big waves also arose from the interviews. Optimal mental approach and preparation techniques are discussed that will enable big wave riders, and other extreme athletes, to more safely and successfully manage extreme situations.

The determinants and motives for young people to participate in surfing

This study examined factors associated with young peoples involvment with surfing. Drawing on Self-Determination Theory, the individual determinant, motivation, was examined to determine if specific motives are associated with young peoples decision to participate in surfing and if these motives vary according to age and gender.The findings suggest that the determinants and motives for young people to participate in surfing are similar for males and females.

Prevalence of health promotion policies in sports clubs in Victoria, Australia

In recent years, some health agencies offered sponsorship to sporting associations to promote healthy environments by encouraging clubs to develop health-related policies. However, the extent to which these sponsorship contracts reach their stated aims is of concern. This study aimed to quantify levels of policy development and practice in sports clubs for each of five key health areas, namely smoke-free facilities, sun protection, healthy catering, responsible serving of alcohol and sports injury prevention. Representatives from 932 Victorian sports clubs were contacted by telephone with 640 clubs (69%) participating in the survey. Results suggested that the establishment of written policies on the key health areas by sports clubs varied widely by affiliated sport and health area: 70% of all clubs with bar facilities had written policies on responsible serving of alcohol, ranging from 58% of tennis clubs to 100% of diving and surfing clubs. In contrast, approximately one-third of sports clubs had a smoke-free policy, with 36% of tennis, 28% of country football and 28% of men's cricket clubs having policy. Moreover, 34% of clubs overall had established sun protection policy, whereas clubs competing outside during summer months, [diving (86%) and life-saving (81%)] were most likely to have a written sun protection policy. Injury prevention policies were established in 30% of sports clubs, and were most common among football (56%), diving (43%) and life-saving (41%). This study suggests that policy development for health promotion can be achieved in sports clubs when it is well supported by health agencies and consideration is given to the appropriateness of the specific behaviours to be encouraged for a given sport. Communication between associations and clubs needs to be monitored by health agencies to ensure support and resources for policy development to reach the club level.

A classification for content adaptation system

Content adaptation is an attractive solution for the ever growing desktop based Web content delivered to the user via heterogeneous devices, in order to provide acceptable experience while surfing the Web. Bridging the mismatch between the rich content and the user device's resources (display, processing, navigation, network bandwidth, media support) without user intervention requires a proactive behavior. While content adaptation poses multitude of benefits, without proper strategies, adaptation will not be truly optimized. There have been many projects focused on content adaptation that have been designed with different goals and approaches. In this paper, we introduce a comprehensive classification for content adaptation system. The classification is used to group the approaches applied in the implementation of existing content adaptation system. Survey on some content adaptation systems also been provided. We also present the research spectrum in content adaptation and discuss the challenges.

A hybrid graphical password based system

In this age of electronic connectivity, where we all face viruses, hackers, eavesdropping and electronic fraud, there is indeed no time when security is not critical. Passwords provide security mechanism for authentication and protection services against unwanted access to resources. A graphical based password is one promising alternatives of textual passwords. According to human psychology, humans are able to remember pictures easily. In this paper, we have proposed a new hybrid graphical password based system, which is a combination of recognition and recall based techniques that offers many advantages over the existing systems and may be more convenient for the user. Our scheme is resistant to shoulder surfing attack and many other attacks on graphical passwords. This resistant scheme is proposed for small mobile devices (like smart phones i.e. ipod, iphone, PDAs etc) which are more handy and convenient to use than traditional desktop computer systems.

"Tomorrow's car" : Deakin Universities new cross vehicle that combines the best of 2 worlds

Motorbike riders are 34-times more likely to die in a crash compared to car drivers per km travelled (1). Such safety risks together with special skill requirements for the driver and much lower comfort compared to normal cars are the main reasons why motorbikes represent only a fraction of all vehicle sales in developed countries. Deakin University is developing a revolutionary cross-over fun vehicle with ultra low fuel consumption and emissions. This new vehicle generation combines the best of two worlds: the fun to drive, low cost, and small size of a scooter together with the safety, comfort and easiness to operate of a car. The result is a vehicle that is more fuel efficient than most cars or even scooters.

Various tilting cross over vehicles have been presented over the last decade that were trying to automate the tilting control of narrow vehicles to make them safer. Examples of these concepts are the Carver, Clever and in some way also the MP3 scooter from Piaggio. The problem with fully enclosed concepts like the Carver or Clever is that they require very complex and therefore also expensive tilting control systems so that the vehicles are not price competitive compared to low cost micro cars or even normal small cars. The MP3 on the other hand comes with a tilting control system which is only semi automatic so that typical car advantages - comprehensive safety features like crush zones, roll over protection, air bags, safety belts or comfort features like full weather protection including heating and cooling – can not be provided.

Deakin’s approach is quite different to the above mentioned concepts. The requirements were derived based on two different investigations: The first step was a critical evaluation of social trends and the second step was an in-depth benchmarking study of existing concepts which identified the typical strengths and weaknesses of these concepts. In a critical next step a new concept was created that addresses most of the weaknesses of existing tilting three-wheelers in a holistic approach by setting clear priority rankings for the vehicle targets, based on current trends. The priorities were set in the following order: Safety, Affordability, Fun and Efficiency (SAFE).

The key feature that enables an enclosed tilting vehicle is a fully automatic tilting control system. With an automatic tilting control system the driver does not need to put the feet on the ground to balance the vehicle when he stops, so the vehicle can be built with a full enclosure. This allows the implementation of typical car like safety features (seat belts, roll over structure, crush zones, air bags). The SafeRide™ tilting control system is a passive system that involves the driver’s balancing sense in its feedback control system. The vehicle has typical scooter like steering characteristics, where the steering is initiated through countersteering. Another safety critical design feature is the crush zone between the two front wheels which is not possible with only one front wheel or with the powertrain positioned between the front wheels, as the powertrain can’t absorb a lot of energy due to its structural stiffness and density. The passive tilting control system is quite simple and therefore makes the vehicle very affordable, an important factor for successful commercialisation.

Another advantage of integrating the human balancing senses in the feedback control of the tilting system is that the system kicks in slightly after the human balancing reacts. In some instances that can generate the typical adrenalin thrill known from riding a bike. This fun factor is quite common with many trend sports like mountain biking, surfing, roller-skating, snowboarding, or skateboarding. Some of these sports have seen very rapid growth only a short time after they have been invented. Utilising the human balancing system during driving also makes the vehicle safer as the adrenalin is produced after reaching a semi-stable driving condition that is controlled by the vehicles tilting control system, but before the vehicle reaches an unstable driving condition that can not be controlled by the vehicle but only (eventually) by the driver – if he has got the required driving skill and if he is alert enough.

Efficiency superior to most cars and scooters is achieved by the aerodynamics of a fully enclosed body structure in combination with the small frontal area of a typical scooter and the droplet shape enabled by the relatively wide front with 2 wheels and the very narrow tail with only one rear wheel. The passive tilting system also contributes to the extreme efficiency as the system only draws some small electrical power for the electronic control unit. Another feature is a low cost exhaust energy recovery system which is discussed in another paper.

Assessment of performance properties of wetsuits

Wetsuits are an integral part of surfing especially in the southern regions of Australia. There is currently little information about mechanical, comfort and thermal properties of wetsuits. There is a demand from wetsuit manufacturers to better understand the neoprene properties and wetsuit performance. The performance characteristics of eight topselling wetsuits, from both high end and low end of the market, were examined. These characteristics include thickness, elasticity, bursting strength, hydrophobicity, thermal conductivity and seal strength. Tensile assessment revealed that neoprene foam was strong and its stretch recovery was well beyond 1.6 times of the original length. Neoprene was found to be hydrophobic with very low surface energy. High-end wetsuits with higher thickness showed slightly higher thermal resistance than low-end wetsuits, indicating that both thickness and bulk density of neoprene influenced thermal properties. High-end wetsuits with fluid seal were stronger than low-end wetsuits with stitched seal.

The janus face of new media propaganda: The case of Patani neojihadist YouTube warfare and its Islamophobic effect on cyber-actors

Surfing on the Internet 2.0 revolution, Patani 2.0 has allowed Patani neojihadist militants to access new competitive spaces and create their own imagined online community by penetrating new realms of the Internet. This article discusses the use of new media militant propaganda by Patani militants and how it is Janus faced. It further examines how the Patani 2.0 social interaction enabled by social media such as YouTube leads to group cohesion among certain actors and the formation of a collective identity that is clustered around the notions of Muslim victimization and defensive jihad; and how, at the same time, it reinforces antithetical identities and fosters group identity competition, where one religious group is often pitted against another. As a result, the Janus effect of Patani neojihadist YouTube online propaganda, while it primarily seeks to radicalize, also generates a reactionary, often virulent, anti-Muslim response from the movement's critics.

Surf and turf: music education riding the wave and/or planted firmly in teacher education arts courses across two Australian universities

Tertiary Arts educators are exhorted to offer The Australian Curriculum: The Arts (Dance, Drama, Media Arts, Music and Visual Arts) in their teacher education programs. This paper situates itself across two interstate universities (Deakin in Victoria and Griffith in Queensland) where both authors are music educators at these institutions. They discuss the two different ways that primary Arts education is offered at their universities by focusing on the Bachelor of Primary course (program/degree). The focus at Griffith University is on integrating the Arts whereas at Deakin University, the Arts are taught as a discipline within the unit (subject). Across both universities two teaching units for primary Arts education is core within the four-year program. Drawing on the author’s narrative reflection, observation, student questionnaire data, anecdotal feedback and student end of semester evaluations we discuss two different methods of delivery, assessment and challenges the units present to the authors and students. Though tertiary Arts educators are challenged to be inclusive of a rich and diverse arts curriculum as music educators we question whether the students are merely surfing the crest of the wave or being firmly planted in the ground to effectively implement music education in their future primary classrooms. We invite dialogue with other music educators who face similar situations where the delivery of music education is not located within the Arts and is dependent on staffing, resourcing and time limits and in some situations is almost drowning.
