The current study addressed how the timing of interviews affected children's memories of unique and repeated events. Five- to six-year-olds (N= 125) participated in activities 1 or 4 times and were misinformed either 3 or 21 days after the only or last event. Although single-experience children were subsequently less accurate in the 21- versus 3-day condition, the timing of the misinformation session did not affect memories of repeated-experience children regarding invariant details. Children were more suggestible in the 21- versus 3-day condition for variable details when the test occurred soon after misinformation presentation. Thus, timing differentially affected memories of single and repeated events and depended on the combination of event-misinformation and misinformation-test delays rather than the overall retention interval.

Aim: The koala is a widely distributed Australian marsupial with regional populations that are in rapid decline, are stable or have increased in size. This study examined whether it is possible to use expert elicitation to estimate abundance and trends of populations of this species. Diverse opinions exist about estimates of abundance and, consequently, the status of populations. Location: Eastern and south-eastern Australia Methods: Using a structured, four-step question format, a panel of 15 experts estimated population sizes of koalas and changes in those sizes for bioregions within four states. They provided their lowest plausible estimate, highest plausible estimate, best estimate and their degree of confidence that the true values were contained within these upper and lower estimates. We derived estimates of the mean population size of koalas and associated uncertainties for each bioregion and state. Results: On the basis of estimates of mean population sizes for each bioregion and state, we estimated that the total number of koalas for Australia is 329,000 (range 144,000-605,000) with an estimated average decline of 24% over the past three generations and the next three generations. Estimated percentage of loss in Queensland, New South Wales, Victoria and South Australia was 53%, 26%, 14% and 3%, respectively. Main conclusions: It was not necessary to achieve high levels of certainty or consensus among experts before making informed estimates. A quantitative, scientific method for deriving estimates of koala populations and trends was possible, in the absence of empirical data on abundances.

Accuracy of triage decisions is a major influence on patient outcomes. Triage nurses' knowledge and experience have been cited as influential factors in triage decision-making. The aim of this article is to examine the independent roles of factual knowledge and experience in triage decisions. All of the articles cited in this review were research papers that examined the relationship between triage decisions and knowledge and/or experience of triage nurses. Numerous studies have shown that factual knowledge is an important factor in improving triage decisions. Although a number of studies have examined the role of experience as an independent influence on triage decisions, none have found a significant relationship between experience and triage decision-making. Factual knowledge appears to be more important than years of emergency nursing or triage experience in triage decision accuracy. Many triage education programs are underpinned by the assumption that knowledge acquisition will result in improved triage decisions. A better understanding of the relationships between clinical decisions, knowledge, and experience is pivotal for the rigorous evaluation of education programs.

This paper proposes an intelligent decision-support system for managing manufacturing technology investments. The intelligent system is a hybrid integration of two information processing modules: case-based reasoning and fuzzy ARTMAP – a supervised adaptive resonance theory (ART) neural network with a multi-dimensional map. The developed system captures a company's strategic information, provides facilities to quantify qualitative attributes and analyses them alongside the quantitative attributes in an evaluation framework. Through the system, similar cases can be retrieved to enable managers to make effective use of their knowledge and experience of previously delivered technologies and projects as an input to the prioritization of future projects. Other salient features of the system include its ability to adapt and absorb new knowledge and responses pertaining to significant events in the business environment, as well as to extract and elucidate information from the knowledge database for explaining and justifying its analysis. The applicability of the developed system is evaluated using a real case study in collaboration with a pharmaceutical manufacturing firm.

Background
use of virtual reality and commercial gaming systems (VR/gaming) at home by older adults is receiving attention as a means of enabling physical activity.

Objective
to summarise evidence for the effectiveness and feasibility of VR/gaming system utilisation by older adults at home for enabling physical activity to improve impairments, activity limitations or participation.

Methods
a systematic review searching 12 electronic databases from 1 January 2000–10 July 2012 using key search terms. Two independent reviewers screened yield articles using pre-determined selection criteria, extracted data using customised forms and applied the Cochrane Collaboration Risk of Bias Tool and the Downs and Black Checklist to rate study quality.

Results
fourteen studies investigating the effects of VR/gaming system use by healthy older adults and people with neurological conditions on activity limitations, body functions and physical impairments and cognitive and emotional well-being met the selection criteria. Study quality ratings were low and, therefore, evidence was not strong enough to conclude that interventions were effective. Feasibility was inconsistently reported in studies. Where feasibility was discussed, strong retention (≥70%) and adherence (≥64%) was reported. Initial assistance to use the technologies, and the need for monitoring exertion, aggravation of musculoskeletal symptoms and falls risk were reported.

Conclusions

existing evidence to support the feasibility and effectiveness VR/gaming systems use by older adults at home to enable physical activity to address impairments, activity limitations and participation is weak with a high risk of bias. The findings of this review may inform future, more rigorous research.

Aims: To determine the prevalence of potentially inappropriate medications (PIMs) in older people aged 65years and over who were admitted to hospital, and to examine the medications and medication classes that comprised these PIMs with use of the Screening Tool of Older Person's Prescriptions. Method: Using a retrospective clinical audit design, the medical records of 100 older patients were randomly selected and examined for the prevalence and characteristics of PIMs. The audit was undertaken of patients admitted over a 12-month period to an Australian public teaching hospital. Results: In total, 92 individual occurrences of PIMs were detected, and 54 patients had at least one PIM. The most common type of PIM experienced related to prescribed medications that adversely affected individuals who were prone to falls. Conclusion: Many older patients experienced a PIM during their hospital admission, where the risk of an adverse event could outweigh the clinical benefit.

This paper explores the views of international students and academic staff on the use of prior professional experience in disciplinary academic writing in Australian higher education. The main finding of this case study indicates that disciplinary practice related to the issue of whether, and how, students should represent aspects of their prior professional experience in disciplinary writing seems to be differently reproduced from the lenses of international student and lecturers. Within the current higher education practices, the diverse dimensions of prior professional experiences that international students bring into the learning context appear to count more in oral class discussion than in academic writing and in formal assessment. Furthermore, despite the rhetoric of internationalization of the curriculum and “inclusivity”, the valid academic practices of international students seem to be marginalized and delegitimized due to the very subtlety and inconsistence of the lecturers’ expectations. The paper concludes with the implications for institutions to more effectively address the needs of international students in terms of knowledge construction in the process of implementing diversity principles within the internationalization agenda.

This paper explores the potential for using metaphors to enable two and three year old children to interact independently with a computer earlier than is traditionally accepted. They need appropriate cognitive skills, the development of which is dependent on the provision of suitable activities; they need adequately developed physical skills to interact with the hardware and necessary knowledge of expected behaviours for interaction. The authors argue that such expectations can be conveyed via the use of metaphors and will employ a purpose-built multimedia product Television Metaphor (TVM) as an example in order to support their discussion. As the TVM software has hitherto demonstrated, age appropriate metaphors using source domains familiar to young children can guide children in the requisite interactions for independent computer use. TVM was created to contextualise theoretical discussions into interface design and to synthesise the ensuing analysis into an applied form.

This study examines the effects of prior experience in the context of a cultural arts service. This is an exploratory study designed to investigate the role familiarity plays in shaping visitor expectations. A cross sectional sample of novice and experienced visitors to a major art exhibition was conducted to investigate expectations, perceptions and service quality. Although the results are inconclusive, the findings provide some support for the proposition that novices have more fragmented expectations in certain dimensions.
