Designing and maintaining websites can be costly for small business, therefore the decision to embark on a Web strategy should not be taken lightly. Critical to the success of a web site is its design. Most small business web sites focus on information provision yet for many it would appear there is a lack of understanding of how to design a web site that delivers information effectively to users. This paper presents research that examined the effectiveness of small business web sites from the perspective of users. Findings indicate that: users found many sites contained too much irrelevant information; users were critical of sites where not enough information was provided; how the text is organised is important; and, the quality and quantity of information provided on the websites and the display and size of the text influenced the ability of users to complete the task and not be frustrated. The paper concludes with recommendations on more effective information design.

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.

Prior research suggests that the online provision of course materials can have a positive impact on students' examination performance. This study adds to the existing literature by investigating the link between the students' use of different forms of online course provisions and tools (i.e. course materials, links and discussion forums) and the final examination performance of students in a second year undergraduate accounting course. Findings indicate a positive association between the number of online files viewed by students, the number of online discussion messages posted by them, and their examination performance. A significant relationship was not found between examination performance and the amount of time spent on the subject's web site, the viewing of links to web sites that were not core to the course being studied, or the passive reading of discussion messages. These findings support the benefits to be gained by providing course materials online and encouraging students to access the materials posted and to participate actively in online discussion.

Purpose - Using staff focus groups in the redevelopment of a library web site deploys their knowledge of user navigation issues and search strategies and addresses the unique needs of library staff. This paper seeks to describe the process of planning, recruiting, and conducting staff focus groups and provide a discussion of lessons learned. Design/methodology/approach - A committee of professionals and non-professionals from the University of Calgary Library conducted a series of five focus groups with library staff. The goals were to determine their content and service priorities for the redesigned library web site, and also to ensure that staff was included in the redesign process. Findings - This paper makes recommendations for library staff focus group interviewing, including planning, formulating questions, recruitment, conducting sessions, and analysis and reporting. Practical implications - Focus group interviews can be effectively conducted in-house, with careful planning and adherence to established guidelines. Focus groups are a very useful method for gathering staff input for web site redesign or any other library-planning project. Originality/value - This paper will be useful to librarians interested in assessing staff needs and priorities through focus group interviews. The paper fills a void in the library literature regarding the use of library staff as both focus group leaders and participants.

In recent years, the online delivery of educational material has received much attention by researchers. University web sites are being used to supplement the delivery of knowledge in traditional bricks and mortar environments or as stand-alone external courses. The function of a university web site also has broader applications that can provide strategic benefits to the organisation as a whole. An Internet presence based on a high quality, easy to use web site can provide universities with a credible, professional image. This is particularly important as students and other users of university web sites expect the same high level of quality in these sites as they do from the sites of commercial organisations. This paper explores the various roles that a web site can provide to benefit higher education organisations and their customers. In addition, the paper outlines the results of a study of university web site users that identifies specific web site design features that are considered essential for a high quality university site that will meet the needs of students and other stakeholders in a university environment. By adopting these design principles, universities will be able to improve the quality of their web sites and ultimately, increase user satisfaction. Moreover, an understanding of the various roles that a web site can perform will allow universities to fully utilise the benefits of developing and maintaining an online presence while retaining their traditional role as knowledge managers.

This paper reports a case study of end-user control in delivery of Web-based electronic services. The case study concentrates the adoption of a Web-based electronic system being implemented in processing student’s admission applications on a Web site. The end-user’s control interface provides information on the detail existing in the Web-based electronic service. This insight into end-user synthesis in developing effective control in Web service environment relates to ease of use in doing the task. To assume the leverage of end-user control strictly on the basis of the Web service usage would limit the purpose of understanding. Rather it is suggested that it would be better to develop an approach to study the end-user ease of use interface in doing the task with the user’s perception towards Web-based interactivity.

The Internet has the potential for delivering innovative, interactive physical activity (PA) interventions to large numbers of people. This study was designed to test the efficacy of an Internet intervention that consisted of a Web site plus 12 weekly e-mail tip sheets, compared with a waiting list control group. The Internet intervention was theory based and emphasized clear, graphical presentation of PA information. Sixty-five (30 intervention and 35 control) sedentary adult employees of several large hospitals (9 men and 56 women) were randomly assigned to 1 of the 2 study arms. Of the 65 participants, 57 completed the 1-month follow-up, and 52 completed the 3-month follow-up. At both 1 and 3 months, those in the intervention group were significantly more likely to have progressed in stage of motivational readiness for PA than participants in the control group: 1 month, c2(1, N =52) =4.05, p <.05; 3 months, c2(1, N =52) =6.45, p <.01. We hypothesized that at 1 and 3 months, the intervention group would exhibit significant increases relative to the control group on the number of minutes of moderate activity. At the 1-month assessment, the intervention group did exhibit significant increases, relative to the control group in moderate minutes, F(1, 54) =5.79, p <.05; however, at the 3-month assessment this difference was no longer significant. In addition, secondary analyses were conducted to examine total number of minutes of walking reported. At 1 month, the intervention group did exhibit significant increases, relative to the control group, in walking minutes, F(1, 54) =12.1, p <.001. At the 3-month assessment, amount of time spent in walking activity continued to be significantly higher for the intervention group compared with the control group, F(1, 48) =5.2, p <.05. These findings show that a theoretically based PA Web site and weekly e-mail tip sheets can have a short-term impact on PA motivation and behavior both at 1 and 3 months. As Internet access increases, and as bandwidth and other technical attributes of this medium improve, Web site delivered health behavior interventions will become increasingly useful in public health promotion.

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.

We present a case study of scanning 3D objects for the purposes of education and public information. We begin by describing the original design of a 3D scanning system now in use in Cairo’s Egyptian Museum. The system captures both the geometry and surface color and detail of museum artifacts. We report on the experience using the system in the museum setting, and how practical problems with the system were addressed. We present samples of how the processed 3D data will be used on a web site designed to communicate Egyptian culture.We present a case study of scanning 3D objects for the purposes of education and public information.

In this article, I draw on Judith Butler's notion of performativity to investigate the role of digital technologies in processes of gendered subjectification (or ‘girling’) in elite girls' education. Elite girls' schooling is a site where the potential of digital technologies in mediating student‐led constructions and explorations of ‘femininity’ sits alongside school‐produced digital media in the form of promotional texts, in which young femininity is regulated by discourses of ‘girl power’. Whilst such schools are well equipped with digital resources that might be utilised towards students' interrogation of how ‘femininity’ is understood, thus politicising the girling process, school‐produced digital media inscribe a more prescriptive picture of ‘who’ an elite school‐girl can ‘be’. Lyla Girls' Grammar School (LGGS) is an elite secondary school in Melbourne, Australia. I report on research undertaken at two institutional levels of LGGS: the ‘school’ level in which digital media representations of young women are produced by the school and the ‘classroom’ level, in which media education pedagogy includes interactive web conferencing software. The use of digital technologies in media education appeared to support student‐led construction and interrogation of femininities to some extent. I argue that this kind of student‐led girling is important in the context of more prescriptive school‐level girling practices.
