Data and information quality is a well-established research topic and gradually appears on the decision-makers' top concern lists. Many studies have been conducted on how to investigate the generic data/information quality issues and factors by providing a high-level abstract framework or model. Based on these previous studies, this study tries to discuss the actual data quality issues with the operation-level and middle-level managers emerged during the emergency department data collection and reporting processes. By conduct data quality issues and business processes mapping, possible data quality issues are summarised under the well-known TOP model and the recommendations of data quality improvement are suggested.)

Computer-aided design decision support has proved to be an elusive and intangible project for many researchers as they seek to encapsulate information and knowledge-based systems as useful multifunctional data structures. Definitions of ‘knowledge', ‘information', ‘facts', anddata' become semantic footballs in the struggle to identify what designers actually do, and what level of support would suit them best, and how that support might be offered. The Construction Primer is a database-drivable interactive multimedia environment that provides readily updated access to many levels of information aimed to suit students and practitioners alike. This is hardly a novelty in itself. The innovative interface and metadata structures, however, combine with the willingness of national building control legislators, standards authorities, materials producers, building research organisations, and specification services to make the Construction Primer a versatile design decision support vehicle. It is both compatible with most working methodologies while remaining reasonably future-proof. This paper describes the structure of the project and highlights the importance of sound planning and strict adhesion to library-standard metadata protocols as a means to avoid the support becoming too specific or too paradigmatic.

As more digital data become publicly available new opportunities for researchers in education are arising. Researchers may be unaware of the existence and usefulness of such data even though these are freely available. In this article the use of one such source of information is described and its potential for research into research education discussed. We sought to exploit the research potential of the existing, yet dispersed, collection of online Australian thesis records to inform their research into the development of the PhD in Australia. Having created a searchable and reliable database from the available records, bibliometric analyses enabled us to map knowledge production and research capability in institutional and disciplinary settings from 1949 to 2003 as indicated by PhD theses. This is in contrast to the more familiar use of data based on student load or completion rates, and complements that data by focusing on research output as opposed to student throughput.

Findings from informetric research represent an important background resource to add to the mix of information useful for resolving difficult and ongoing problems in specific library environments or information service settings. This paper provides examples of informetric research that can be useful input to decision-making in the field of library management and information service provision. This overview takes four of the challenges that Michael Buckland outlined for library research as a way of guiding the discussion of ways that informetric work can be used to inform library decision-making. (1) References are made to relevant informetric work undertaken or conducted in Australia, by Australian researchers, or with Australian data.

Informetrics includes both quantitative and qualitative methods, which when used in combination can provide a rounded set of findings that has great validity for management, policy and service applications. Quantitative methodologies are generally based on bibliometric techniques, such as mining and analysis of data from various bibliographic and textual databases. Qualitative methods include survey, case study and historical approaches. Used in combination, each set of findings adds richness and other perspectives to an analysis.

The Australian government is currently committed to the goal of increasing organisational participation in employee share ownership plans (ESOP) from 4% of all companies to 11% by 2009. The Nelson Report into ESOPs commissioned by the Honourable Brendan Nelson highlighted the lack of comprehensive information on the nature and extent of ESO plans in Australia. This paper places the program in context by reviewing overseas experiences and considers the viewpoints of both employers and employees. The preliminary investigation concludes by highlighting the need for further thorough research before success for all types of businesses can be confidently predicted.

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.

This study investigates information literacy and scholarly communication within the processes of doctoral research and supervision at a distance. Both doctoral candidates and supervisors acknowledge information literacy deficiencies and it is suggested that disintermediation and the proliferation of information may contribute to those deficiencies. Further to this, the influence of pedagogic continuity—particularly in relation to the information seeking behaviour of candidates—is investigated, as is the concomitant aspect of how doctoral researchers practise scholarly communication. The well-documented and enduring problem for candidates of isolation from the research cultures of their universities is also scrutinised. The contentious issue of more formally involving librarians in the doctoral process is also considered, from the perspective of candidates and supervisors. Superimposed upon these topical and timely issues is the theoretical framework of adult learning theory, in particular the tenets of andragogy. The pedagogical-andragogical orientation of candidates and supervisors is established, demonstrating both the differences and similarities between candidates and supervisors, as are a number of independent variables, including a comparison of on-campus and off-campus candidates. Other independent variables include age, gender, DETYA (Department of Education, Training & Youth Affairs) category, enrolment type, stage of candidature, employment and status, type of doctorate, and English/non-English speaking background. The research methodology uses qualitative and quantitative techniques encompassing both data and methodological triangulation. The study uses two sets of questionnaires and a series of in-depth interviews with a sample of on-campus and off-campus doctoral candidates and supervisors from four Australian universities. Major findings include NESB candidates being more pedagogical than their ESB counterparts, and candidates and supervisors from the Sciences are more pedagogical than those from Arts, Humanities and Social Sciences, or Education. Candidates make a transition from a more dependent and pedagogically oriented approach to learning towards more of an independent and andragogical orientation over the duration of their candidature. However, over tune both on-campus and off-campus candidates become more isolated from the research cultures of their universities, and less happy with support received from their supervisors in relation to their literature reviews. Ill The study found large discrepancies in perception between the support supervisors believed they gave to candidates in relation to the literature review, and the support candidates believed they received. Information seeking becomes easier over time, but candidates face a dilemma with the proliferation of information, suggesting that disintermediation has exacerbated the challenges of evaluation and organisation of information. The concept of pedagogic continuity was recognised by supervisors and especially candidates, both negative and positive influences. The findings are critically analysed and synthesised using the metaphor of a scholarly 'Club' of which obtaining a doctorate is a rite of passage. Recommendations are made for changes in professional practice, and topics that may warrant further research are suggested.

Background
The study was undertaken to evaluate the contribution of a process which uses clinical trial data plus linked de-identified administrative health data to forecast potential risk of adverse events associated with the use of newly released drugs by older Australian patients.

Methods
The study uses publicly available data from the clinical trials of a newly released drug to ascertain which patient age groups, gender, comorbidities and co-medications were excluded in the trials. It then uses linked de-identified hospital morbidity and medications dispensing data to investigate the comorbidities and co-medications of patients who suffer from the target morbidity of the new drug and who are the likely target population for the drug. The clinical trial information and the linked morbidity and medication data are compared to assess which patient groups could potentially be at risk of an adverse event associated with use of the new drug.

Results
Applying the model in a retrospective real-world scenario identified that the majority of the sample group of Australian patients aged 65 years and over with the target morbidity of the newly released COX-2-selective NSAID rofecoxib also suffered from a major morbidity excluded in the trials of that drug, indicating a substantial potential risk of adverse events amongst those patients. This risk was borne out in post-release morbidity and mortality associated with use of that drug.

Conclusions
Clinical trial data and linked administrative health data can together support a prospective assessment of patient groups who could be at risk of an adverse event if they are prescribed a newly released drug in the context of their age, gender, comorbidities and/or co-medications. Communication of this independent risk information to prescribers has the potential to reduce adverse events in the period after the release of the new drug, which is when the risk is greatest.

Note: The terms 'adverse drug reaction' and 'adverse drug event' have come to be used interchangeably in the current literature. For consistency, the authors have chosen to use the wider term 'adverse drug event' (ADE).

Background: Colorectal cancer (CRC) is the third most commonly diagnosed cancer in males and the second in females throughout the developed world. Population screening using fecal occult blood tests (FOBTs) facilitates early detection and greater chance of survival, but participation rates are low. We developed a Web-based decision tool to provide information tailored to an individual’s decision stage for CRC screening and attitude toward screening utilizing the Preventive Health Model (PHM) and Precaution Adoption Process Model (PAPM) as theoretical frameworks for screening behavior. We describe the practical steps employed in the tool’s design and the subsequent conduct of an exploratory study.
Objective: To design a decision tool for CRC screening and conduct an exploratory study among average-risk men and women to (1) test the impact of message type (tailored vs non-tailored) and message delivery modality (Web-based vs paper-based) on attitudes toward screening and screening uptake, and (2) investigate the acceptability of the decision tool and relevance of materials.
Methods: Participants (n = 100), recruited from a population sample of men and women aged 50-76 residing in urban Adelaide, Australia, were randomly assigned to a control group or one of 4 interventions: (1) Web-based and tailored information, (2) paper-based and tailored information, (3) Web-based and non-tailored (generic) information, or (4) paper-based and non-tailored information. Participation was augmented by snowball recruitment (n = 19). Questionnaires based on PHM variables were administered pre- and post-intervention. Participants were given the opportunity to request an FOBT. Following the intervention, participants discussed the acceptability of the tool.
Results: Full data were available for 87.4% (104/119) of participants. Post-intervention, perceived susceptibility scores for individuals receiving tailored information increased from mean 10.6 (SD 2.1) to mean 11.8 (SD 2.2). Scores on self-efficacy increased in the tailored group from mean 11.7 (SD 2.0) to mean 12.6 (SD 1.8). There were significant time x modality x message effects for social influence and salience and coherence, reflecting an increase in these scores for tailored Web-based participants only; social influence scores increased from mean 11.7 (SD 2.6) to mean 14.9 (SD 2.3), and salience and coherence scores increased from mean 16.0 (SD 2.2) to mean 17.7 (SD 2.1). There was no greater influence of modality or message type on movement toward a decision to screen or screening uptake, indicating that neither tailored messages nor a Web modality had superior effect. Overall, participants regarded tailored messages positively, but thought that the Web tool lacked “media richness.”
Conclusions: This exploratory study confirms that tailoring on PHM predictors of CRC screening has the potential to positively address attitudes toward screening. However, tailoring on these variables did not result in significantly increased screening uptake. Future research should consider other possible psychosocial influences. Mode of delivery did not affect outcomes, but as a delivery medium, the Web has economic and logistical advantages over paper.

Since Licklider in the 1960s [27] influential proponents of networked computing have envisioned electronic information in terms of a relatively small (even singular) number of 'sources', distributed through technologies such as the Internet. Most recently, Levy writes, in Becoming Virtual, that "in cyberspace, since any point is directly accessible from any other point, there is an increasing tendency to replace copies of documents with hypertext links. Ultimately, there will only need to be a single physical exemplar of the text" [13 p.61]. Hypertext implies, in theory, the end of 'the copy', and the multiplication of access points to the original. But, in practice, the Internet abounds with copying, both large and small scale, both as conscious human practice, and also as autonomous computer function. Effective and cheap data storage that encourages computer users to keep anything of use they have downloaded, lest the links they have found, 'break'; while browsers don't 'browse' the Internet - they download copies of everything to client machines. Not surprisingly, there is significant regulation against 'copying' - regulation that constrains our understanding of 'copying' to maintain a legal fiction of the 'original' for the purposes of intellectual property protection. In this paper, I will firstly demonstrate, by a series of examples, how 'copying' is more than just copyright infringement of music and software, but is a defining, multi-faceted feature of Internet behaviour. I will then argue that the Internet produces an interaction between dematerialised, digital data and human subjectivity and desire that fundamentally challenges notions of originality and copy. Walter Benjamin noted about photography: "one can make any number of prints [from a negative]; to ask for the 'authentic' print makes no sense" [4 p.224]. In cyberspace, I conclude, it makes no sense to ask which one is the copy.

Understanding the waysthatinternational students seek information and help in the host country is essential forimprovingacademic, social, cultural,and welfare support for this student cohort. However,there is a dearth of literature that documentshowinternational studentsin the vocational education and training (VET) sector do so. This paper aims to fill thisgap. Based on in-depth interviews with 30 Chinese international students undertaking diploma and associate degree programsin Australia,this research shows thatthe ways in which Chinese international students seek help prior to their departure and after their arrival at the host country, largely dependson the nature of the issuesthey confront. The data also reveals that students’use of education agents is not limited to the pre-departure stage,asisindicated in theexisting literature, but throughout their journey in the host country. Notably,the role of agents has become increasingly important in Chinese international students’ decision-making processesduring their transition from diploma to associate degree and higher education programs.

The results of an experimental study of retail investors' use of eXtensible Business Reporting Language tagged (interactive) data and PDF format for making investment decisions are reported. The main finding is that data format made no difference to participants' ability to locate and integrate information from statement footnotes to improve investment decisions. Interactive data were perceived by participants as quick and ‘accurate’, but it failed to facilitate the identification of the adjustment needed to make the ratios accurate for comparison. An important implication is that regulators and software designers should work to reduce user reliance on the comparability of ratios generated automatically using interactive data.
