Data processing of physiological sensor data and alarm determination utilising activity recognition

Current physiological sensors are passive and transmit sensed data to Monitoring centre (MC) through wireless body area network (WBAN) without processing data intelligently. We propose a solution to discern data requestors for prioritising and inferring data to reduce transactions and conserve battery power, which is important requirements of mobile health (mHealth). However, there is a problem for alarm determination without knowing the activity of the user. For example, 170 beats per minute of heart rate can be normal during exercising, however an alarm should be raised if this figure has been sensed during sleep. To solve this problem, we suggest utilising the existing activity recognition (AR) applications. Most of health related wearable devices include accelerometers along with physiological sensors. This paper presents a novel approach and solution to utilise physiological data with AR so that they can provide not only improved and efficient services such as alarm determination but also provide richer health information which may provide content for new markets as well as additional application services such as converged mobile health with aged care services. This has been verified by experimented tests using vital signs such as heart pulse rate, respiration rate and body temperature with a demonstrated outcome of AR accelerometer sensors integrated with an Android app.

Parent, peer and media influences on body image and strategies to both increase and decrease body size among adolescent boys and girls

This study investigated the nature of body image and body change strategies, as well as the sociocultural influences on these variables, among a group of 1,266 adolescents (622 males, 644 females). In particular, it investigated weight gain and increased muscle, as well as weight loss. It was found that females were less satisfied with their bodies and were more likely to adopt strategies to lose weight, whereas males were more likely to adopt strategies to increase weight and muscle tone. Respondents with higher body mass index (BMI) evidenced greater body dissatisfaction and more weight loss strategies, but there were no differences between BMI groups in weight gain or strategies to increase muscles. Weight gain and strategies to increase muscles were more likely to be undertaken by older adolescents, but there were no grade level differences in weight loss. Media influences to alter weight, as well as feedback from mother, father, and both male and female peers, were greater for females. There were few grade level or BMI differences in regard to any of the sociocultural influences. The importance of these findings in terms of providing a better understanding of factors which may lead to a disturbed body image and body change disorders, particularly among adolescent boys, is discussed.

The roles of static depth information and object-image relative motion in perception of heading

In a series of 6 experiments, two hypotheses were tested: that nominal heading perception is determined by the relative motion of images of objects positioned at different depths (R. F. Wang & J. E. Cutting 1999) and that static depth information contributes to this determination. By manipulating static depth information while holding retinal-image motion constant during  simulated self-movement, the authors found that static depth information played a role in determining perceived heading. Some support was also found for the involvement of R. F. Wang and J. E. Cutting’s (1999) categories of object-image relative motion in determining perceived heading. However, results suggested an unexpected functional dominance of information about heading relative to apparently near objects.

Body image ideal among males and females: sociocultural influences and focus on different body parts

Past research has obtained mixed findings in relation to gender differences and other factors that shape ideal body image. The current study was designed to investigate these differences further, using a digital body image program to assess body image individually. As expected, females desired a body that was smaller than their current size, whereas males were split between wanting a smaller and larger body. The perceived messages from peers and parents were consistent with the individual's ideal image. Gender differences were also found with ratings of attractiveness and effectiveness. Females rated messages from peers and parents as more important than did males. For both males and females, opposite sex peers were the most important influences, and parents the least important.

Accessing database information using mobile agents

Many real-world applications on the Internet require accessing database information and typical technology employed is client/server plus Web (C/S + Web). Although past few years saw many success applications by using this technique, there are still some drawbacks that need to be overcome. One of the drawbacks is that the transaction often fails if the network connection is unstable. Another disadvantage is high bandwidth requirement and latency. This paper argues that mobile agent technology provide an easy way to overcome the shortcomings in CIS + Web in database access on the Internet. A success case study using mobile agents to admit new students to China's institutions is then presented. The mobile agent was created by using IBM's Aglets Software Development Kit (SDK). Based on the experimental results, it is evident that mobile agent technology is well suited for such applications.

Cultural differences, information and code systems

This paper explores an alternative way of framing information systems research on the role and impact of national culture. It argues that the widely accepted structural framework of Hofstede reduces interpretation to a simplistic categorical description which in many cases ignores differentiation within cultures. The alternative model suggests, that national culture can be better understood by seeking out the dominant codes that frame the discourse pervasive in a culture and understanding how that discourse affects the obvious social codes of ritual, custom and behavior and the textual codes which express the nature of that culture. This framework is applied to two different case studies—one in New Zealand and one in Thailand—to demonstrate its applicability.

Individual and organisational factors influencing academics` decisions to pursue the scholarship and teaching of ICT

This paper focuses on Information and Communication Technology (ICT) academics' perceptions of factors that promote and inhibit their pursuit of scholarship in their teaching work. It identifies critical factors that influence academics' attitudes, orientations and behaviours in respect to the scholarship of teaching, and from these builds a framework for understanding the interaction between these factors. We have named this framework the Scholarship of Teaching Support Framework.

During 2001 and 2002 a national project investigated teaching and learning initiatives in the major discipline of lCT in Australia's universities. As part of this project a mini-conference program was devised to elicit academics' perceptions of the factors influencing their teaching work and their participation in scholarly activities around this work. In total 83 ICT teachers from 29 universities participated in the mini-conference program. Attendees included staff members from a range of academic levels.

In discussions of aspects of the scholarship of teaching at the mini-conference participants referred to both attributes and responses of both university teachers and the university institutions. We have categorized these factors into those that relate to the individual academic (Individual domain) and those that relate to the tertiary institutional system (Organisational domain). Many contributions highlighted the interaction between these two domains.

Within the Individual domain, two key factors described by participants as affecting the pursuit of the scholarship of teaching were teachers' motivation towards, and their capabilities in, scholarly activities surrounding their teaching. Within the organizational domain two influential factors also emerged. These were the organizational support provided through allocation of resources and symbolic support reflected in an institution's systems, policies and processes.

Our findings indicate that both the Individual and Organizational domains contribute to university teachers' decisions to pursue (or not to pursue) the scholarship of teaching.

These two domains were seen by participants to interact within university environments to influence whether a particular environment is supportive or unsupportive in terms of the pursuit of the scholarship of teaching. Factors both from and within the individual and the organizational domains were seen to interact with each other forming a web of interrelated factors that appear to influence individuals' decisions to pursue, or not to pursue, the scholarship of teaching. From this complexity four theoretical extremes emerged providing the dimensions and components of the Scholarship of Teaching Support Framework.

We argue that responsive and innovative approaches to university teaching are best supported by academics undertaking scholarly activities around their teaching work, yet this article presents a picture of a university work environment where scholarly activities that focus on teaching and learning are seen as generally unsupported and unrewarded. This perception was identified as commonalities across a university system. Although some exceptions were noted, participants generally agreed that the organisational domain of Australian universities was largely unsupportive of the pursuit of the scholarship of teaching. Similarly, in general, university ICT teachers were not thought to have the backgrounds and capabilities necessary for pursuing the scholarship of teaching, such as familiarity with literature on teaching and learning and skills in educational evaluation. However, despite perceived inhibitors in universities' organisational culture and allocation of resources, and a perceived lack in individuals' skills, participants agreed that scholarly activities and innovation in university teaching and learning do take place, These are largely driven by the intrinsic motivation of individuals. It was recognised that further work is necessary to explore how motivation can be engendered and encouraged.

The Scholarship of Teaching Support Framework is a useful tool for examining how conducive a given university teaching context is to the scholarship of teaching and, therefore, can be used for review purposes within both research and policy contexts. Such tools will become increasingly important as policy changes begin to affect practices in how university teaching work is managed, supported and encouraged.

Social movement unionism and networked technology

From a European perspective, the wide-ranging social, economic, and political effects of networked computers have generated tensions between 'new' social movements and the 'old' labour movement. From an American perspective on social movements, there is no such tension between old and new social movements. A study of social-movement unionism in Sweden offers a interesting means of testing this emerging American perspective against the European perspective because the labour movement has long been particularly effective and networked technology has been embraced whole-heartedly throughout all aspects of the society, the economy, and the polity. The paper introduces the contrasting European and American perspectives on social movements and presents examples of the practice of social-movement unionism among Swedish social democrats, unionists, and diverse local activists. These examples support conclusions that eschew utopian theories of 'cyberunionism' in favour of developing a theory of articulated unionism in which local unions branches articulate vertically with national and global union bodies, and articulate horizontally with social movements in other arenas of conflict.

The scholarship of teaching: risky business in ICT education

The idea of the scholarship of teaching was reinvigorated twelve years ago by Boyer's (1990) book, Scholarship reconsidered: Priorities of the professoriate. Since then a considerable body of literature has developed, discussing what the scholarship of teaching might look like, why it is desirable and how it might be encouraged. The scholarship of teaching has been described as including the activities involved in designing, implementing and evaluating teaching and learning, and associated dissemination activities. Over the last few years there has been a resurgence of interest in the role that scholarship might play in the promotion, recognition and reward of good university teaching.

This paper draws on qualitative data that were collected as part of a national study of the major university discipline of Information and Communication Technology (ICT) to generate a framework for describing the context of university teaching and for examining how conducive this context is to the scholarship of teaching. The framework comprises two domains: that of the individual educator and that of the organisational environment in which the educator works. The paper highlights the importance of, and interaction between, these domains, and the role they play in promoting or discouraging the scholarship of teaching.

From the comforts of print to the possibilities of digital media: leading the way in teaching political leadership in a faculty of arts

Since it inception, Deakin University has been committed to the delivery of innovative, high quality course materials to its off campus students. Until recently these packages were predominantly print based, although augmented with audio-visual materials delivered in cassette format. Ironically, with the advent of information and communications technologies (ICT), and some select computer assisted learning and multimedia packages, there was an overall decline in the use of audio and video as important means of enhancing learning. Like many other universities, Deakin has moved to a strong, centralised approach to the provision of its digital and online corporate technology environment. With investment in these technologies has come a renewed interest in the ways in which text and audio-visual materials in digital form can enhance students' learning experiences. Moreover, the ways in which a variety of digital media supported by online developments can create new models and approaches to teaching/learning has figured prominently. This paper presents a case study of how this challenge has been taken up in a unit, Political Leadership, in the Faculty of Arts. The academic teacher's intentions in moving to a completely digital approach are examined along with students' experiences of learning in the subject. Issues are considered from the experience.

Games within games: gambling and trickery in professional running

Professional running is an overtly gambling sport in which a clear objective is to maximise winnings from the bookmakers, which is achieved through a careful concealment of a runner’s ability. Professional runners seldom win more than one significant race. Races are deliberately lost until runners acquire a sufficiently lenient handicap to significantly improve their chances of winning a race of their choosing. Successes, kudos and identities in this sport are evaluated from the cleverness of the win, largely measured by the trainer’s effectiveness in executing a gambling coup. The money prizes given to runners may be significantly bettered from gambling winnings and making the most of these is the major emphasis for most successful runners and trainers. Drawing from an ethnographic study of this sport in Australia, the paper argues that the gambling strategies of runners and trainers can be understood as zero-sum games.

A process model to support design and construction

This research is focused on developing a highly detailed understanding of current organisational interactions and information flows leading to a definition of the process model for the environment into which information and communication technology (ICT) applications will be placed. The authors of this paper propose a theoretical process model and the associated detailed information structure which reflects the complexity of information, stakeholder interaction and intellectual property concerns which are currently seen in the construction industry. This is being developed and tested against a field study renovation project. The field study project identifies information flows and interactions between stakeholders such as designers, project managers, clients, contractors, subcontractors and suppliers. The process model which is being established shows very high levels of complexity in dependencies and interdependencies between implicit and explicit information within the project design and construction teams. Without an understanding of these detailed and complex process interactions, proposals for the application of ICT to the construction industry will not reflect the requirements of those for whom they are being developed.
