Swell : a feature-length screenplay set in the world of Australian surfing, and an accompanying exegesis on three-act structure

Despite many arguments to the contrary, the three-act story structure, as propounded and refined by Hollywood continues to dominate the blockbuster and independent film markets. Recent successes in post-modern cinema could indicate new directions and opportunities for low-budget national cinemas.

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 (A Thomson, Darcy and Pearce 2010). The consensus is that physical activity is an important contributor to health for all people (Nelson, Abbott and Macdonald 2010). While there is strong research interest, what remains unclear is the value and impact of sport and physical activity on Indigenous communities (Cairnduff 2001). Nelson (2009) drawing on the work of Jonas and Langton (1994) indicates that an ‘Aboriginal person is a descendant of an Indigenous inhabitant of Australia, identifi es as an Aboriginal, and is recognised as Aboriginal by members of the community in which he or she lives’ (p. 97). Even this defi nition has the potential to be politically charged. At a general level, the collective terms ‘Indigenous’ (capitalised) and ‘Aboriginal and Torres Strait Islander’ people (title capitalised) appear to be broadly acceptable terms. Indigenous groups cannot be considered to be homogenous as there is much diversity between and within groups (Nelson et al. 2010; Parker et al. 2006). 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-specifi c surfi ng programs.

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.

Combating shoulder-surfing: a hidden button gesture based scheme

This project describes an authentication technique that is shoulder-surfing resistant. Shoulder surfing is an attack in which an attacker can get access to private information by observing the user’s interaction with a terminal, or by using recording tools to record the user interaction and study the obtained data, with the objective of obtaining unauthorized access to a target user’s personal information. The technique described here relies on gestural analysis coupled with a secondary channel of authentication that uses button pressing. The thesis presents and evaluates multiple alternative algorithms for gesture analysis, and furthermore assesses the effectiveness of the technique.

Artificial Surfing Reefs per la difesa e riqualificazione della costa: ipotesi progettuale a Cattolica (RN)

Un artificial surfing reef (di seguito ASR) è un’importante opera che ha come obiettivo principe la riproduzione di onde e correnti ideali per eseguire il surf. Com’è noto, questo spettacolare sport si basa sul processo di frangimento delle onde che si propagano a riva. Ciò nonostante gli ASR possono servire come opere di difesa dall’erosione della spiaggia essendo in grado di smorzare sulla loro cresta l’energia ondosa. In questo lavoro di tesi si andrà ad analizzare quali parametri sono necessari per rendere uno paraggio fruibile dai surfers assieme ad una disamina degli effetti che un ASR può ingenerare sull’idrodinamica della costa, oltre a definire compiutamente i criteri di progettazione di un reef artificiale, basandoci su studi pregressi di progettisti e su evidenze sperimentali condotte su modelli fisici. Applicheremo tali criteri progettuali ad un caso pratico sulle coste emiliano - romagnole, nella provincia di Rimini laddove il fiume Conca sfocia in Adriatico. Ci baseremo su una progettazione di massima dell’ASR ed infine, anche sulla base di una sommaria analisi dei costi, valuteremo quale alternativa meglio si addica allo stato della costa e del litorale della regione.

Cluster of Leptospirosis Acquired Through River Surfing in Switzerland

Background.  In Switzerland, leptospirosis is still considered as a travel-associated disease. After the surprising diagnosis of leptospirosis in a patient who was initially suspected as having primary human immunodeficiency virus infection, we recognized that acquisition of leptospirosis occurred through recreational activities and we identified additional affected individuals. Methods.  Detailed anamnesis, excluding occupational exposure, acquisition abroad, and pet contacts, enabled us to detect the source of infection and identify a cluster of leptospirosis. Convalescent sera testing was performed to confirm Leptospira infection. Microscopic agglutination tests were used to determine the infecting serovar. Results.  We identified a cluster of leptospirosis in young, previously healthy persons. Acquisition of leptospirosis was traced back to a surfing spot on a river in Switzerland (Reuss, Aargau). Clinical presentation was indistinct. Two of the 3 reported cases required hospitalization, and 1 case even suffered from meningitis. Serologic tests indicated infection with the serovar Grippotyphosa in all cases. With the exception of the case with meningitis, no antibiotics were administered, because leptospirosis was diagnosed after spontaneous resolution of most symptoms. Despite a prolonged period of convalescence in 2 cases, full recovery was achieved. Recent reports on beavers suffering from leptospirosis in this region underline the possible water-borne infection of the 3 cases and raise the question of potential wildlife reservoirs. Conclusions.  Insufficient awareness of caregivers, which may be promoted by the missing obligation to report human leptospirosis, combined with the multifaceted presentation of the disease result in significant underdiagnosis. More frequent consideration of leptospirosis as differential diagnosis is inevitable, particularly as veterinary data suggest re-emergence of the disease.

Surfing the high energy output branch of nonlinear energy harvesters

Hysteresis and multistability are fundamental phenomena of driven nonlinear oscillators, which, however, restrict many applications such as mechanical energy harvesting. We introduce an electrical control mechanism to switch from the low to the high energy output branch of a nonlinear energy harvester by exploiting the strong interplay between its electrical and mechanical degrees of freedom. This method improves the energy conversion efficiency over a wide bandwidth in a frequency-amplitude-varying environment using only a small energy budget. The underlying effect is independent of the device scale and the transduction method and is explained using a modified Duffing oscillator model.
