There is increasing coverage in the literature relating to the different facets surrounding the security service of authentication, but there is a need for further research into the usability of graphical authentication. Specifically, the usability and viability of graphical authentication techniques for providing increased security needs to be further explored. There is a significant amount of evidence relating to traditional authentication techniques which highlight the fact that as technological advances grip modern societies, the requirement for more advanced authentication and security approaches increases. The exponential growth in the number of people using the Internet carries with it the high potential for increased security threats, suggesting that there are needs for further techniques to increase security in online environments. This paper presents the findings of how various interface design approaches affect the usability of a previously developed alternative graphical authentication technique called AuthentiGraph. The security design provided by Authentigraph has been established and justified in previous research by the authors. The primary focus of this paper is the usability of this technique. Using an experimental laboratory based approach, combined with an online survey, 20 university students evaluated a combination of five varying graphical interfaces in three different screen sizes. The outcome provides the interface design criteria best suited for the implementation and use of the AuthentiGraph technique.

A social movement known as Stitch’nBitch has emerged around the globe. This movement, mainly of women, is based in local, third places, such as hotels and clubs, and virtually. Using the Internet, particularly Blogs, the women meet to knit, stitch and talk. These groups use technology as an enabler and resource exchange. In this presentation, we suggest that such groups may be a response to consumerism in the Information Society, which has resulted in profound changes in the way people live, communicate and connect with one another and which has also provided a trigger for new, more community-focused activities using craft production, rather than consumption, as a vehicle. Craft production, or ‘make it yourself’ is consistent with concepts of voluntary simplicity (Etzioni, 1998) and non-materialistic satisfactions (Shaw and Newholm, 2002). We introduce five themes to assist in the development of a research agenda into this new form of material culture, discussing (1) remedial, (2) progressive, (3) resistance, (4) nostalgic, and (5) ironic possibilities.

In the late 1980s, Melbourne was the hub of the computer underground in Australia, if not the world. The hackers who formed the underground were not disgruntled computer professionals or gangs of organised criminals. They were disaffected teenagers who used their basic home computers to explore the embryonic Internet from inside their locked, suburban bedrooms. From this shadowy world emerged two elite hackers known as Electron and Phoenix, who formed part of an alliance called The Realm. In the Realm of the Hackers charts Electron's journey from his initial innocent explorations to his ultimate obsession. It vividly recreates the climate of the 1980s, before there was public access to the Internet. The program takes us headlong into the clandestine, risky but intoxicating world of the computer underground to uncover not only how the hackers did it but why.

Taking its cue from the conference at which it was presented, this article considers both old stories and new ways, and addresses the question of the impact not only of new technology but also of politics upon 'the story'. Fundamental is the question of whether politics and technology might be considered friends or enemies of the story. Drawing on her long term experiences as an interviewer, the author interrogates particular oral history projects undertaken into children's play lore and play ways, to show how children's games and play time activities have been politicised. Locating her analysis in an international context of US legislation and British and Australian research, the author examines how play itself has become the plaything of both politicians and fear. She then examines the impact of high fidelity recording equipment and the universal accessibility of material located on the internet to address the question of technology as friend of the story, ultimately concluding that the story and the question will both go on.

The Internet can access a large number of consumers in a more cost-effective manner than other information delivery channels. In this pilot study, we assessed whether an online weight reduction program including dietary advice plus exercise (ED) was more effective in reducing weight than an exercise-only program (EX) >12 weeks. Participants were randomized to either the ED or EX group and attended a center for anthropometric measurements and dietary assessment. Both groups wore a pedometer and set weekly goals to increase daily steps through an interactive Web site. The ED group set weekly dietary goals via the Web site and received tailored e-mail assistance. Seventy-three participants commenced and 53 (73%) completed the study [EX n = 26; ED n = 27; body mass index—mean (standard deviation): 29.7 (2.5) kg m–2, age 46.3 (10.8); 21% male]. Percent weight changes were EX, 2.1 (0.6)% and ED, 0.9 (0.6)% (P = 0.15). Both groups increased their daily steps with no difference between groups. Only the ED group significantly reduced their energy intake. Despite a greater fall in energy intake reported by the ED group and a similar increase in physical activity in both groups, setting individual dietary goals did not enhance weight loss.

This study compared Panic Online (PO), an internet-based CBT intervention, to best-practice face-to-face CBT for people with panic disorder with or without agoraphobia. Eighty-six people with a primary diagnosis of panic disorder were recruited from Victoria, Australia. Participants were randomly assigned to either PO (n = 46) or best practice face-to-face CBT (n = 40). Effects of the internet-based CBT program were found to be comparable to those of face-to-face CBT. Both interventions produced significant reductions in panic disorder and agoraphobia clinician severity ratings, self reported panic disorder severity and panic attack frequency, measures of depression, anxiety, stress and panic related cognitions, and displayed improvements in quality of life. Participants rated both treatment conditions as equally credible and satisfying. Participants in the face-to-face CBT treatment group cited higher enjoyment with communicating with their therapist. Consistent with this, therapists’ ratings for compliance to treatment and understanding of the CBT material was higher in the face-to-face CBT treatment group. PO required significantly less therapist time than the face-to-face CBT condition.

This paper explores the implementation of a creativity support system (CSS) for tertiary students studying Games Design and Development at Deakin University, Victoria, Australia. The students at the centre of this study are the ‘next’ generation of learners and are often called the Internet generation because of their pre-imposed for ‘online’ and being ‘connected’. The CSS for the games students is designed within a context that encompasses a ‘whole’ system, as focusing on only one component to augment a person’s creativity does not take into consideration the multitude of factors, for example social factors, that are pertinent on a person ability to grow their creative behaviours. This study will present a set of factors that each CSS should employ to facilitate creative abilities within people, with particular focus on how social activities help to enhance creativity.

Objective : The study aimed to measure changes in dining behaviour associated with the introduction of smoking restrictions on July 1, 2001, to describe strategies adopted by smokers and non-smokers to adapt to the changes, and to describe some of the thoughts, feelings and beliefs underlying the adaptations that people make in response to the introduction of new restrictions.

Method : Data were collected in a longitudinal study with repeated measures of a total of 257 respondents before and after the introduction of the restrictions, using a questionnaire administered via the Internet. Data collection occurred on seven occasions between April 2001 and March 2002. In addition, a series of in-depth telephone interviews was conducted among a group of 31 smokers and non-smokers, who were interviewed once before and twice after the introduction of the bans.

Results :
Dining patterns, dining frequency, restaurant choice and expenditure on a meal did not change among either smoking or non-smoking patrons following the introduction of the law. The majority of Victorians approved of smokefree dining legislation before its implementation, and agreement with the law increased sharply and significantly among both smokers and non-smokers immediately following the introduction of the policy, remaining at high levels for the duration of the study period.

Conclusions : These findings suggest there was rapid adaptation to and acceptance of the restrictions among both smokers and non-smokers, and are supported by evidence from other jurisdictions, both interstate and internationally, regarding the introduction of smokefree dining.

With the advent of Web 2.0 tools such as Weblogs (blogs), lay people can more easily share knowledge with the public and have far greater reach and impact. At the same time a literature review reveals that experts have been criticised on many fronts. This paper explores key criticisms of experts using 1) a literature review and 2) an interpretive study of lay blogger perceptions of experts. The paper provides important insights into lay blogger criticisms of experts. Findings indicate that a major lay blogger criticism of experts is class-based and powerbased. Experts are perceived as elitists who wish to control the flow of knowledge. Interestingly, many of the lay bloggers studied held mixed feelings about experts and the value of lay knowledge on the internet. Implications for theory and practice are discussed.

Aims and objectives. To identify the preferred content and delivery mode of education information for people aged 25 to 45 with type 2 diabetes to enable them to effectively self-manage their diabetes.

Background. People with type 2 diabetes are required to manage their own health and initiate behavioural changes. Self-management education and resources have typically been targeted at people aged 50 years and older. Little is known about the concerns and needs of younger people in managing type 2 diabetes, which are likely to be different from those of older people.

Design. A qualitative design was considered the most appropriate to elicit participants' views and perceptions of their type 2 diabetes information needs.

Methods. Data were obtained from one focus group (n = 9) and telephone interviews (n = 4) with people aged 25 to 45 with type 2 diabetes conducted in 2008.

Results. Implicit in participants' responses was their need to be active partners in managing their diabetes. Participants wanted information that is easy to understand, brief, consistent, age-specific and about a number of topics that are not adequately covered at present. They wanted a centralised source of information and a range of delivery mode options. Participants expressed some ambivalence about the Internet as a source of information. Participants also wanted age-specific group sessions, support from peers, psychological support, increased understanding of type 2 diabetes in the community, and a focus on preventing diabetes.

Conclusions. Young people with type 2 diabetes have specific diabetes needs and preferred information delivery modes. Participants felt current diabetes education programs do not cater specifically to their age group. Education and information resources need to be developed for the target group, addressing their content and format preferences.

Relevance to clinical practice. Health professionals need to utilise appropriate delivery modes and include information relevant to younger people when providing education information to young adults with type 2 diabetes.

The ‘single most important technological discovery since the birth of the p.c.’, (Gates, 1996). The swift increase in Internet utilisation within businesses and surveying has changed working methods within UK based Surveying practices. User numbers expanded rapidly since the early 1990’s and estimates place a figure of 150 million internet users globally (www.Yahoo.com, 2000). Sloan and Kee Low (2000) established that ‘e-commerce’ is a revolutionary way of trading and conducting business activities. There are opportunities for surveying practices including, reducing communication time, increasing revenues from new and existing sources, enhanced client satisfaction and competitive advantage (Cronin, 1996). Others (Dixon, 1998) perceive threats, such as ‘disintermediation’, to the traditional role of the surveyor.

This research examined the levels of internet and intranet access within the UK Building and Quantity Surveying practices and corporate firms to establish how the internet has affected working methods and client requirements. The research method comprised a qualitative approach using an email and postal questionnaire survey of a random sample of practices. The questionnaire findings formed the basis of semi structured interviews conducted with senior management of large practices to gain a deeper understanding of the issues identified within the survey.

Data analysis revealed the traditional role of the surveyor as a broker of information may be under threat in the long term. Generally levels of internet access in the sample exceed that of general business levels (Dti, 2000) with the largest growth pre 1997. The perceived advantages and barriers to Intranet and Internet usage were identified by the research.

The electronic revolution has proven to be a powerful stimulus for change in business practice. As a business tool however, the Internet must endure the same scrutiny under which other business activities are placed. If the use of the Internet in business is a sound strategy, then it must contribute toward competitive advantage. The sport business industry has not been isolated from the vagaries of Internet applications. Moreover, as the industry has become more competitive, forcing sporting organisations towards unprecedented levels of accountability and business practice, the Internet has been increasingly seen as a potential 'holy grail' for sport organisations struggling for revenue (Stewart & Smith, 1999). This research is a response to these pressures. It seeks to identify Internet based opportunities for competitive advantage, and to provide strategies and recommendations for the successful use of the Internet in Australian professional sport organisations. In realising this objective, a newly developed and integrated Business Activity Model has been constructed. The model assists in the identification of specific Internet based competitive advantage strategies, and provides a theoretical framework for this research. The Business Activity Model conceptualises, for the first time, the relationships between the value chain, constituents of electronically enabled competitive advantage, and the Internet. With Australia's limited group of fully professional sports capable of sustaining the human resources and budgets necessary to implement comprehensive e-commerce strategies, the organisations selected to participate in this research represent the pinnacle of Australian professional sport clubs. Specifically, the 55 clubs competing in the Australian Football League (A.F.L.), National Basketball League (N.B.L.), National Rugby League (N.R.L.), and National Soccer League (N.S.L.) constituted the research sample and population. In concert with the 87% participation rate, sampling approached a census. A telephone-administered survey, based primarily on the rigorously tested instrument developed by Sethi and King (1994), was employed for data collection. This research employs a comprehensive set of descriptive statistics, and is bolstered by a confirmatory and an exploratory factor analysis, undertaken on one component of the data. The outcome of this research was the identification of seven practical recommendations for Australian professional sport organisations seeking to improve competitive advantage via the Internet. These recommendations were based on an inventory of the 'gaps' between the strategies proposed by the literature, and the practices of the sample, and relate to both overall Internet strategy, and specific web site applications. The development of the new Business Activity Model and the identification of key online strategy themes support and complement these recommendations. An examination of variations in the practices of participating organisations, and some comparisons against United States sporting organisations, also provides depth and context to the findings. This research provides a platform for sport managers to effectively harness the potential of the Internet, through their web sites in particular, and realise significant competitive advantages. The Business Activity Model provides managers in all industries with a tool for the detection and understanding of potential elements of competitive advantage, and incorporates all activities critical to business in the new digital economy. Seven practical recommendations for improved online performance based on identified competitive advantage and strategies fulfils the primary objective of this research. E-commerce continues to grow at astronomical rates, and with the Internet poised to become the life-blood of 21st century sporting organisations, these recommendations will assist managers in their ongoing search for competitive advantage.

The advent of the Internet and the World Wide Web has been instrumental in bringing about the growth in the implementation of web-based information systems (WBIS). Such systems are designed with the aim of improving productivity, data accuracy, and the reduction of paperwork and administrative overheads. Moreover, unlike their conventional non-web-based predecessors, the WBIS are commonly aimed at users who are casual and untrained, geographically distributed and non-homogenous. The dissemination of WBIS necessitates additional infrastructure support in the form of a security system, workflow and transaction management, and web administration. WBIS are commonly developed using an evolutionary approach, whereby the version of the application, acquired from the vendor, is first deployed as a pilot, in order to gather feedback from the target users before the evolutionary cycles commence. While a number of web development methodologies have been proposed by existing research, there is a dearth of empirical evidence that elucidates the experiences of project initiators in pursuing the evolution of web services, a process that undoubtedly involves dealing with stakeholder issues. This research project presents a phenomenological investigation of the experiences of project managers with the implementation of web-based employee service systems (ESS), a domain that has witnessed a sharp growth in Australia in recent times. However, the project managers’ rich, multidimensional account of their experiences with the implementation of ESS revealed the social obstacles and fragility of intra-organizational relationships that demanded a cautious and tactful approach. Thus, the study provides a socio-organizational perspective to web projects in contrast to the functionalist paradigm of current web development methodologies. The research also confirms that consideration of the concerns of stakeholders by project managers is crucial to the successive cycles of ESS evolution. Project managers address stakeholder concerns by pursuing actions that are aimed at encouraging ESS usage, but at the same time, such actions can have consequences necessitating subsequent iterations of system enhancement and improvement. Finally, the research also discovered that despite the different socio-political climate prevalent in various organizations, in which ESS are being implemented, the experiences of project managers in dealing with stakeholder concerns can be captured and independently confirmed in terms of their perceived relevance and usefulness in problem-solving within the application domain.
