Cognitive intervention in autism using multimedia stimulus

We demonstrate an open multimedia-based system for delivering early intervention therapy for autism. Using exible multi-touch interfaces together with principled ways to access rich content and tasks, we show how a syllabus can be translated into stimulus sets for early intervention. Media stimuli are able to be presented agnostic to language and media modality due to a semantic network of concepts and relations that are fundamental to language and cognitive development, which enable stimulus complexity to be adjusted to child performance. Being open, the system is able to assemble enough media stimuli to avoid children over-learning, and is able to be customised to a specific child which aids with engagement. Computer-based delivery enables automation of session logging and reporting, a fundamental and time-consuming part of therapy.

Integrating e-simulations in teaching business information systems

Students’ early exposure to the fundamentals of business and Information and Communications Technologies (ICT), creation of a professional skill base, as well as, the gaining of practical experience in applying such knowledge and skills, are the determinants of success in their study and development as Information Systems (IS) professionals. This chapter argues that e-simulations, or computer-based and online simulations, can be effectively used to engage learners in interactive learning activities and provide them with real world practical experience in the safety of an educational setting. A research project is subsequently described. A suite of e-simulations were developed and deployed across two institutions to support teaching and learning of Information Systems. Using staff discussions and online surveys, quantitative and qualitative data were collected from the staff and students. The collected data were then analysed to evaluate and guide a sequence of curriculum and technology changes with a view to arriving at an optimum support model for students and teachers using the e-simulations. The findings of the study emphasise the usefulness of e-simulations to accommodate the learning styles of generation Y students, to stimulate their interest and creative thinking, and in meeting industry expectations of IS graduates’ ability to fulfil professional roles. Based on these insights, in its concluding remarks, the chapter outlines a conceptual framework for the inclusion of e-simulations in Information Systems curriculum development and teaching delivery.

The impact of a computerised consolidation accounting package (CCAP) on student performance

Purpose – The purpose of this paper is to investigate the association between the use of a computerised learning tool (specifically designed to teach consolidation accounting) and student performance in the final examination of an undergraduate accounting unit on Corporate Accounting.

Design/methodology/approach – A regression model was developed to analyse 1,103 observations of assignment and examination scores, collected over three semesters, to test the central proposition that computer assisted learning enhances student learning outcomes and performance in the exam.

Findings – The results show a positive and significant relationship between the computerised accounting assignment on consolidated accounting (linked to usage of the computerised tool) and the consolidation question in the final examination. The findings suggest that the computerised consolidation accounting package (CCAP) assists students to understand the concepts underpinning consolidation accounting.

Research limitations/implications – The data were collected from a single institution, which may not represent the population of accounting students. Due to ethical obligations, the study lacked a control group that would have allowed meaningful comparison and assessment of student performance. Furthermore, whilst the findings in this study were able to demonstrate a positive association between the CCAP and exam performance, it is unable to determine the quality and depth of the learning experience from using the CCAP.

Practical implications – The present study found that a CCAP and its usage has the potential to positively impact student performance on assessment tasks on subject matter similar to concepts contained the computer package. Such findings may encourage instructors to seek ways of incorporating learning technologies in the pedagogical design.

Originality/value – This is believed to be one the few papers that has exclusively studied the impact of a specific CCAP and a specific segment in accounting education (consolidation accounting) using direct measures, CCAP assignment score and the final examination score for a question dedicated to consolidation accounting.

User preference of cyber security awareness delivery methods

Operating systems and programmes are more protected these days and attackers have shifted their attention to human elements to break into the organisation's information systems. As the number and frequency of cyber-attacks designed to take advantage of unsuspecting personnel are increasing, the significance of the human factor in information security management cannot be understated. In order to counter cyber-attacks designed to exploit human factors in information security chain, information security awareness with an objective to reduce information security risks that occur due to human related vulnerabilities is paramount. This paper discusses and evaluates the effects of various information security awareness delivery methods used in improving end-users’ information security awareness and behaviour. There are a wide range of information security awareness delivery methods such as web-based training materials, contextual training and embedded training. In spite of efforts to increase information security awareness, research is scant regarding effective information security awareness delivery methods. To this end, this study focuses on determining the security awareness delivery method that is most successful in providing information security awareness and which delivery method is preferred by users. We conducted information security awareness using text-based, game-based and video-based delivery methods with the aim of determining user preferences. Our study suggests that a combined delivery methods are better than individual security awareness delivery method.

K-Complex Detection Using a Hybrid-Synergic Machine Learning Method

Sleep stage identification is the first step in modern sleep disorder diagnostics process. K-complex is an indicator for the sleep stage 2. However, due to the ambiguity of the translation of the medical standards into a computer-based procedure, reliability of automated K-complex detection from the EEG wave is still far from expectation. More specifically, there are some significant barriers to the research of automatic K-complex detection. First, there is no adequate description of K-complex that makes it difficult to develop automatic detection algorithm. Second, human experts only provided the label for whether a whole EEG segment contains K-complex or not, rather than individual labels for each subsegment. These barriers render most pattern recognition algorithms inapplicable in detecting K-complex. In this paper, we attempt to address these two challenges, by designing a new feature extraction method that can transform visual features of the EEG wave with any length into mathematical representation and proposing a hybrid-synergic machine learning method to build a K-complex classifier. The tenfold cross-validation results indicate that both the accuracy and the precision of this proposed model are at least as good as a human expert in K-complex detection.

The impact of test medium on use of visual analogue scales

Objectives: Visual analog scales are frequently used as a means of allowing participants to rate symptoms during clinical trials. The accuracy and reproducibility of these scales play an important role in determining the experimental value of the data they provide. This study was initiated to compare the data collected using paper- and computer-based (Tablet PC) analog scales to better understand the variability in data provided by a visual analog scale.

Methods: Thirty participants rated ocular comfort, redness, and clarity of vision (right and left eyes) on a nondemarcated horizontal line on both paper and a Tablet PC. Measurements were taken in the morning between the hours of 8:30 and 10:30 am and again the same day between 2:30 and 4:30 pm.

Results: The mean difference between the measures recorded in the morning for the 2 media was 2.6 ± 0.9 (confidence intervals, 2 standard errors of the differences) units on a 100 unit scale, with the Tablet PC having the higher mean measure. The limits of agreement (2 standard deviations of the differences) was 9.4 units. Comparing the difference of the differences (1.0 ± 1.3) between the 2 methods of measure (morning vs. afternoon) the visual analog scales on the Tablet PC seemed to have good reproducibility of agreement in comparison with the paper version.

Conclusions: Discrepancy analysis yielded no significant difference and slight bias between paper- and computer-based analog scales. Repeatability of measures using the Tablet PC was also demonstrated. These results suggest that the choice of medium does not significantly influence the outcome for subjective analog scales.

Shared care for chronic eye diseases : perspectives of ophthalmologists, optometrists and patients

Objective: To report the perspectives of optometrists, ophthalmologists and patients on a model of shared care for patients with chronic eye diseases.

Design, setting and participants: Qualitative study of a model of shared care between optometrists and ophthalmologists for patients with stable age-related macular degeneration, diabetic retinopathy and glaucoma, trialled by the Royal Victorian Eye and Ear Hospital in Melbourne during 2007–2009. Semi-structured interviews were conducted with optometrists, ophthalmologists and patients at completion of the project to obtain their perspectives on this model.

Results: Seventeen optometrists submitted expressions of interest to participate, and 12 completed web-based training modules and clinical observerships and adhered to specified examination and reporting protocols. All five participating ophthalmologists and 11 of the optometrists were interviewed. Ninety-eight patients participated and 37 were interviewed. Optometrists not only met ophthalmologists’ expectations but exceeded them, appropriately detecting and referring patients with additional, previously undetected conditions. Patients reported savings in travel time and were satisfied with the quality of care they received. Optometrists, ophthalmologists and patients indicated a general acceptance of shared care arrangements, although there were some issues relating to interprofessional trust.

Conclusions: Shared care between local optometrists and hospital-based ophthalmologists can help to reduce patient waiting time for review and offers an opportunity for these two groups of eye care professionals to collaborate in providing localised care for the benefit of patients. However, trust and relationship building need to be further developed.

Video driven traffic modelling in ParamicsTM

With urbanization and vehicle availability, there exist many traffic problems including congestion, environmental impact and safety. In order to address these problems, we propose a video driven traffic modelling system in this paper. The system can simulate real-world traffic activities in a computer, based on traffic data recorded in videos. Video processing is employed to estimate metrics such as traffic volumes. These metrics are used to update the traffic system model, which is then simulated using the Paramics™ traffic simulation platform. Video driven traffic modelling has widespread potential application in traffic systems, due to the convenience and reduced costs of model development and maintenance. Experiments are conducted in this paper to demonstrate the effectiveness of the proposed system.

Teaching international students in vocational education : new pedagogical approaches

Teaching International Students in Vocational Education: New pedagogical approaches is designed to support vocational education teachers in both addressing the distinctive learning characteristics of international students and preparing domestic students for global skills mobility in the ‘Asian Century’.

Well-grounded in theories about teaching and learning in vocational and international education, and supported by empirical data drawn from interviews with teachers and program managers, the book expounds several evidence-based, highly effective, pedagogical approaches within the context of competency-based training. These include:
- the intercultural approach
- the Ubuntu approach
- the language and vocational learning integration approach
- the perspective transformation approach
- the value-added approach
- work-based learning
- flexible and divergent pedagogy.

These approaches focus on developing the learner’s ability to consider the broader issues in an intercultural context, to capitalise on prior experience and to adapt vocational skills to workplace settings transnationally. The underpinning theory is brought to life with real-world exemplars, ‘Implications for Practice’, quotes and insights from teachers, as well as reflective questions throughout the book.

More than a game: evaluation report

‘More than a Game’ is a sport-based youth mentoring program developed and implemented by Western Bulldogs in partnership with Newport Islamic Society (NIS), the Australian Federal Police, Victoria Police and Hobsons Bay City Council, with funding from the Attorney General’s Department Building Community Resilience (BCR) grant scheme. The program aimed to develop a community-based resilience model that would use team-based sports to address issues of identity, sense of belonging and cultural isolation amongst young men of Islamic faith, all of which are identified as factors that may promote forms of violent extremism. The program involved 60 young men, aged 15-25, from the Newport Islamic Society in Melbourne’s Western suburbs. The boys were engaged in numerous activities where they were mentored by staff from Western Bulldogs, Victoria Police and Australian Federal Police, who worked in conjunction with community leaders from the Newport Islamic Society.

Through sports-based training, mentoring programs, and community dialogue, ‘More Than a Game’ aimed to develop participants’ leadership, communication, and cross-cultural engagement skills; to identify and facilitate the development of young role models in the community; to enhance greater understanding of the Muslim community in Melbourne’s West, and to foster greater intercultural contact and understanding between participants and other cultural groups. A number of activities were developed and implemented as a part of the program

A study protocol to investigate the management of depression and challenging behaviors associated with dementia in aged care settings

Background: 

On film character retrieval in feature-length films

The problem of automatic face recognition (AFR) concerns matching a detected (roughly localized) face against a database of known faces with associated identities. This task, although very intuitive to humans and despite the vast amounts of research behind it, still poses a significant challenge to computer-based methods. For reviews of the literature and commercial state-of-the-art see [21, 372] and [252, 253]. Much AFR research has concentrated on the user authentication paradigm (e.g. [10, 30, 183]). In contrast, we consider the content-based multimedia retrieval setup: our aim is to retrieve, and rank by confidence, film shots based on the presence of specific actors. A query to the system consists of the user choosing the person of interest in one or more keyframes.

Knowledge management in future factories

Technology in the manufacturing sector has seen rapid change, transforming from stand alone, manual processes to smart, integrated systems. We have witnessed the migration of relay-based systems to advance SCADA systems, manual pro-duction to fully automated, and hand written reports to interactive computer-based dashboards. We are now seeing the emergence of smart products manufactured in smart plants and the evolution of smart services in manufacturing. Future manu-facturing systems will be distinguished by intelligent machines, automation and human factors’ integration. This talk will focus on how knowledge can be embed-ded in processes and products through the use of simulation and modelling tools to streamline future smart production systems and improve product quality. The implications to future smart manufacturing enterprises are explored through a se-ries of case studies from aerospace, mining and small and medium manufacturing enterprises.
