Spatial mapping and map exploitation : a bio-inspired engineering perspective

Probabilistic robot mapping techniques can produce high resolution, accurate maps of large indoor and outdoor environments. However, much less progress has been made towards robots using these maps to perform useful functions such as efficient navigation. This paper describes a pragmatic approach to mapping system development that considers not only the map but also the navigation functionality that the map must provide. We pursue this approach within a bio-inspired mapping context, and use esults from robot experiments in indoor and outdoor environments to demonstrate its validity. The research attempts to stimulate new research directions in the field of robot mapping with a proposal for a new approach that has the potential to lead to more complete mapping and navigation systems.

Twenty first century trends in silicone hydrogel contact lens fitting : an international perspective

Silicone hydrogel contact lenses were introduced into the market in 1999. To assess prescribing trends of this lens type since then, up to 1000 survey forms were sent to contact lens fitters in Australia, Canada, Japan, the Netherlands, Norway, the UK and the USA each year between 2000 and 2008. Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Analysis of returned forms revealed a rapid increase in the prescribing of silicone hydrogel lenses over the survey period. In 2008, silicone hydrogel lenses represented 36% of all soft lenses prescribed. The categorization of the majority of lenses prescribed as ‘refits’ is primarily attributed to the mass conversion of lens wearers from hydrogel to silicone hydrogel lenses. Silicone hydrogels may soon represent the majority of soft contact lenses prescribed.

Improving reflective writing in higher education : A social semiotic perspective

Reflective skills are widely regarded as a means of improving students’ lifelong learning and professional practice in higher education (Rogers 2001). While the value of reflective practice is widely accepted in educational circles, a critical issue is that reflective writing is complex, and has high rhetorical demands, making it difficult to master unless it is taught in an explicit and systematic way. This paper argues that a functional-semantic approach to language (Eggins 2004), based on Halliday’s (1978) systemic functional linguistics can be used to develop a shared language to explicitly teach and assess reflective writing in higher education courses. The paper outlines key theories and scales of reflection, and then uses systemic functional linguistics to develop a social semiotic model for reflective writing. Examples of reflective writing are analysed to show how such a model can be used explicitly to improve the reflective writing skills of higher education students.

The digital economy bill and the UK’s creative industries : a perspective from China

The Digital Economy Bill has been heavily criticized by consumer organizations, internet service providers and technology experts on the grounds that it will reduce the public’s ability to access politically sensitive information, impinge on citizens’ rights to privacy, threaten freedom of expression and have a chilling effect on digital innovation. Its passage in spite of these criticisms reflects, among other things, the power of the rhetoric that has been employed by its proponents. This paper examines economic arguments surrounding the digital economy debate in light of lessons from one of the world's fastest growing economies: China.

Potential of St John's Wort for the treatment of depression : the economic perspective

The burden of rising health care expenditures has created a demand for information regarding the clinical and economic outcomes associated with complementary and alternative medicines. Meta-analyses of randomized controlled trials have found Hypericum perforatum preparations to be superior to placebo and similarly effective as standard antidepressants in the acute treatment of mild to moderate depression. A clear advantage over antidepressants has been demonstrated in terms of the reduced frequency of adverse effects and lower treatment withdrawal rates, low rates of side effects and good compliance, key variables affecting the cost-effectiveness of a given form of therapy. The most important risk associated with use is potential interactions with other drugs, but this may be mitigated by using extracts with low hyperforin content. As the indirect costs of depression are greater than five times direct treatment costs, given the rising cost of pharmaceutical antidepressants, the comparatively low cost of Hypericum perforatum extract makes it worthy of consideration in the economic evaluation of mild to moderate depression treatments.

Avoidance of advertising on social networking sites : the teenage perspective

Technology has provided consumers with the means to control and edit the information that they receive and share effectively, especially in the online environment. Although previous studies have investigated advertising avoidance in traditional media and on the Internet, there has been little investigation of advertising on social networking sites. This exploratory study examines the antecedents of advertising avoidance on online social networking sites, leading to the development of a model. The model suggests that advertising in the online social networking environment is more likely to be avoided if the user has expectations of a negative experience, the advertising is not relevant to the user, the user is skeptical toward the advertising message, or the consumer is skeptical toward the advertising medium.

Sports sponsorship as an integrated marketing communications tool : an Australian sponsor's perspective

Sports sponsorship increasingly provides organisations with the opportunity to reach their target audiences in a manner that facilitates engagement and encourages relationship development. This paper provides an Australian perspective of the value of sports sponsorship using a case study of WOW Sight and Sound’s long-term sponsorship of the Brisbane Broncos rugby league team. The case study investigates WOW’s marketing objectives which centre generating brand awareness using sponsorship with the Brisbane Broncos as an integrated marketing communications tool. WOW believes that the integration of its sponsorship of the Broncos with the team’s total marketing plan is integral to its success. This integration requires the facilitation of two-way communications between WOW, its advertising agency, the Brisbane Broncos and customers to ensure that all parties’ needs are met.

Dealing with unique interests in Crown Land : a Queensland perspective

Security of tenure is the cornerstone of the land management system in Australia. Freehold title is protected throug indefeasibility of title entrenched in legislation and protection of registrable interests in land is offered through the Statutory Assurance Fund. For those with interests pertaining to Crown Land no such protection is offered, although this position is not uniform across Australia. Notably those with Crown leasehold interests or a profit a prendre on Crown Land in Queensland are not protected through registration on the freehold land register and do not have the benefit of indefeasibility of title. The issue of management of interests pertaining to Crown Land has become increasingly relevant due to the complexities associated with balancing public interests including native title with more commercial interests in land generated through carbon sequestration, forestry and mining. This paper considers the framework for the management of Crown Land in Queensland and the adequacy of this framework for commercial interests that pertain to Crown Land.

Citizen consultation from above and below : the Australian perspective

Citizen engagement and e‐government initiatives in Australia remain somewhat underdeveloped, not least for a number of fundamental structural reasons. Fledgling initiatives can be divided into a number of broad categories, including top‐down government consultation through blogs and similar experimental online sites operated by government departments; bottom‐up NGO‐driven watchdog initiatives such as GetUp!’s Project Democracy site, modelled on projects established in the UK; and a variety of more or less successful attempts by politicians (and their media handlers) to utilise social networking tools to connect with constituents while bypassing the mainstream media. This chapter explores these initiatives, and discusses the varying levels of success which they have found to date.

Modelling web search behaviour : a user’s cognitive style perspective [Unpublished]

Many researchers have investigated and modelled aspects of Web searching. A number of studies have explored the relationships between individual differences and Web searching. However, limited studies have explored the role of users’ cognitive styles in determining Web searching behaviour. Current models of Web searching have limited consideration of users’ cognitive styles. The impact of users’ cognitive style on Web searching and their relationships are little understood or represented. Individuals differ in their information processing approaches and the way they represent information, thus affecting their performance. To create better models of Web searching we need to understand more about user’s cognitive style and their Web search behaviour, and the relationship between them. More rigorous research is needed in using more complex and meaningful measures of relevance; across a range of different types of search tasks and different populations of Internet users. The project further explores the relationships between the users’ cognitive style and their Web searching. The project will develop a model depicting the relationships between a user’s cognitive style and their Web searching. The related literature, aims and objectives and research design are discussed.

Affordable housing solutions : affordable housing providers’ perspective

Accessibility to housing for low to moderate income groups in Australia has experienced a severe decline since 2002. On the supply side, the public sector has been reducing its commitment to the direct provision of public housing. Despite strong demand for affordable housing, limited supply has been generated by non-government housing providers. This paper identifies and discusses some current affordable housing solutions which have been developed by non-government housing providers to ameliorate the problem. This study utilises case studies generated from nineteen housing providers during in-depth interviews in South East Queensland in 2007-2008. The case studies are classified into four categories which relate to the nature of their product: affordable rental housing, mixed housing, affordable housing for people with special needs and low cost home ownership. Each category is discussed on the basis of the characteristics typical of that organisation of housing provider, their partnership arrangements and main target market. In addition, the special design and facilities required for people with special needs which include high care accommodation and aged care are highlighted. Finally, this study recommends offering a continuum of solutions to affordable housing for low income people by means of a rent-to-buy scheme.

Providing a law degree for the “real world” : perspective of an Australian law school

The Queensland University of Technology badges itself as “a university for the real world”. For the last decade the Law Faculty has aimed to provide its students with a ‘real world’ degree, that is, a practical law degree. This has seen skills such as research, advocacy and negotiation incorporated into the undergraduate degree under a University Teaching & Learning grant, a project that gained international recognition and praise. In 2007–2008 the Law Faculty undertook another curriculum review of its undergraduate law degree. As a result of the two year review, QUT’s undergraduate lawdegree has fewer core units, a focus on first year student transition, scaffolding of law graduate capabilities throughout the degree,work integrated learning and transition to the workplace. The revised degree commenced implementation in 2009. This paper focuses on the “real world” approach to the degree achieved through the first year programme, embedding and scaffolding law graduate capabilities through authentic and valid assessment and work integrated learning.

Brisbane floods : a traffic and transport perspective

Flood-besieged Brisbane residents were forced to watch the monster river consume their homes and livelihoods then see the receding water leave behind a putrid, tar-like sludge. The rains formed by multiple low pressure systems over Central Queensland caused chaos over the Christmas and New Year break for many parts of Queensland.
