Sustainable living environment for urban low-income households in Malaysia : key factors for maintenance

Urbanisation is predicted to continuously increase every year. Demand for urban shelter will rise and hence this will force governments to act, within their capability, to provide affordable housing in order to maintain social and economic stability. Some industrialized countries have demonstrated full state support from planning and implementation through to continuing maintenance in order to create and sustain a healthy living environment for urban low-in-come households. For developing countries, this might be more difficult. Ensuring adequate maintenance to provide housing quality over the long term is proving even more problematic than simply providing housing. The question is how housing in developing countries can be made sustainable in order to provide a better living environment in the long term. This study focuses on key issues of residential living environments for urban low-cost housing in Malaysia in relation to housing maintenance management. Drawing from extensive primary research and a series of interviews, this exploratory study identifies factors that must be considered by policy makers in order to provide a decent and sustainable living environment for the urban lower-income group. The outcome suggests that current systems of maintenance management - offsetting maintenance to developers or the housing communities themselves, is not working well. The government may need to continue to support low cost housing through maintenance in order to prevent deterioration of accommodation that could become future slums.

Rethinking curriculum, assessment and reporting in a technology-rich school environment

This research presents a portrait of a school experiencing the dilemmas and tensions of adapting to new technology. Teachers, parents and students' reactions to, and involvement in, the defining of the 'learning community' of the school is analysed and documented as multimodal reporting of student learning and progress is introduced.

Supporting blended learning in an E-learning environment

The main goal of this research was to develop a Blended Learning Model which incorporated traditional learning technologies into e-learning. The model is aimed at assisting students to learn in an environment that contains elements of their preferred learning style whilst still being emerged in the local learning environment.

Reflective positioning : the impact of conversations in the social and cultural environment of midwifery practice settings on professional learning for students

Literature reviews on the topic of reflection and reflective practice encompassed midwifery, nursing, medicine, allied health, education and professional education. This investigation also included socio-psychological theories by leading authors such as Benner (nursing), Schön (professional education) and positioning theory by Harré and others. Positioning is a psycho-sociological ontology in which individuals metaphorically position themselves within three entities: people, institutions, and societies, where conversations are constructed and make an impact upon the social world. The social and cultural structures and interactions developed in Archer’s morphogenesis were examined in terms of the impact of possible encounters and the transformational effects of learning experiences in practice settings. These bodies of work provided the theoretical framework for the author’s research of students’ experiences in midwifery education for postgraduate students from which selected excerpts with three participating students and their supervising midwives are presented. These excerpts are related to reflective practices and the professional conversations conducted between students and midwives. It was found that reflective positioning applied in midwifery education by students can serve as an analytical tool in explaining social and cultural elements of clinical placements to influence and transform their learning. The potency of conversations that occur in everyday moment-to-moment interactions do contribute to students’ induction in professional midwifery practice and their identity formation as a midwife.

Spam filtering for network traffic security on a multi-core environment

This paper presents an innovative fusion-based multi-classifier e-mail classification on a ubiquitous multicore architecture. Many previous approaches used text-based single classifiers to identify spam messages from a large e-mail corpus with some amount of false positive tradeoffs. Researchers are trying to prevent false positive in their filtering methods, but so far none of the current research has claimed zero false positive results. In e-mail classification false positive can potentially cause serious problems for the user. In this paper, we use fusion-based multi-classifier classification technique in a multi-core framework. By running each classifier process in parallel within their dedicated core, we greatly improve the performance of our multi-classifier-based filtering system in terms of running time, false positive rate, and filtering accuracy. Our proposed architecture also provides a safeguard of user mailbox from different malicious attacks. Our experimental results show that we achieved an average of 30% speedup at an average cost of 1.4 ms. We also reduced the instances of false positives, which are one of the key challenges in a spam filtering system, and increases e-mail classification accuracy substantially compared with single classification techniques.

Keeping treasures in testing times : special collections in the academic environment

“… university libraries, while differing in the specifics of their goals, generally embrace the obligation to collect, preserve, and make available primary source materials for both current scholarship and future research” (Hewitt 1998).

This paper explores some of the challenges faced by the Fryer Library, the special collections branch of the University of Queensland Library responsible for manuscripts and pictorial materials, as well as theses and rare books. The challenges are not dissimilar to those being met by other cultural agencies or institutions as well as other academic libraries. The challenges covered include collection development, access and preservation, making appropriate responses to the research imperative, as well as promotion of services and collections, and servicing the community at large. The paper outlines the research library context and concludes with experiences of cross-sectoral collaborations and future opportunities.

An agent architecture for managing data resources in a grid environment

The agent paradigm has been successfully used in a large number of research areas. MAPFS, a parallel file system, constitutes one successful application of agents to the I/O field, providing a multiagent I/O architecture. The use of a multiagent system implies coordination and cooperation among its agents. MAPFS is oriented to clusters of workstations, where agents are applied in order to provide features such as caching or prefetching. The adaptation of MAPFS to a grid environment is named MAPFS-Grid. Agents can help to increase the performance of data-intensive applications running on top of the grid.

This paper describes the conceptual agent framework and the communication model used in MAPFS-Grid, which provides the management of data resources in a grid environment. The evaluation of our proposal shows the advantages of using agents in a data grid.

Expectations and perceptions of overseas students in a Post-graduate corporate accounting subject : a research note

This study examines the expectations and perceptions of overseas students undertaking the post-graduate corporate accounting subject taught at an Australian university. An understanding
of students’ perceptions and expectations in learning of the subject is important in assisting
accounting academics to enhance their teaching programmes, and to manage the diverse student
cohorts which are now a feature of university classrooms in Australia. The findings show that
overseas students expected the post-graduate corporate accounting subject to be challenging and
interesting. Moreover, they expressed a strong desire that the subject should emphasise the
practicalities of accounting.

The client's complex decision-making environment on international mega projects

More than ever before, architectural, engineering and construction (AEC) firms are working on international mega projects. The mega project environment offers a range of opportunities for firms but is but is characterised by a high level of risk and uncertainty. International mega projects bring together networks of people with differing backgrounds and cultures to work in unfamiliar locations to integrate the social, economic, technical and political components of design and construction. Within such an intense environment there is a process of rapid relationship development at an unprecedented level. The interests and power relations on such projects are often very strong given the vast amount of money, jobs, environmental impacts, publicity and national prestige involved. Therefore in a field as costly or consequential as mega project design and construction there is an increased need to effectively manage these projects given the associated high risks of failure. Internationalisation is a relatively new field of research in the AEC sector and past research has tended to focus on explaining the attitudes and behaviour of the industry itself towards improving performance on such projects. To date there has been little research investigating the sophistication of the international client in terms of their regular business environment which is characterised by a set of social, economic and political responsibilities. The values that clients ascribe to their everyday practices and experiences inevitably condition how they act economically, which in turn impacts upon project decision-making. Clients establish the structural organisation of project teams through the procurement strategy and establish the context for effective decision-making. To a large extent they establish a unique culture that project team members need to work within and make decisions. Since clients establish the context within which firms operate the findings of past studies on the industry’s position and attitudes are more indicative than enlightening. Clients occupy a distinctly different position in the construction supply chain and therefore experience and respond to project matters based upon their environment and not the construction industry environment. Clients are confronted with uncertainties and need support to help them understand the critical role that they play in creating good decision-making environments. This theoretical paper seeks to develop a rationale for studying the client’s complex decision-making environment on international mega projects. Specifically it charts the quest for improved industry performance through client leadership as documented in various industry and government publications since the 1940s and highlights that there has been considerable attention to address industry problems through client leadership, however, with little evidence that the issues have been resolved. This paper is positioned within a PhD study, which seeks to move beyond the aspirations of policymakers and idealistic descriptions of how clients ought to behave to explain the reality of what really happens on mega project client decision-making based upon a critique of cultural political economy.

Client leadership capacity on international projects : exploring the client's complex decision-making environment through a critical cultural political economy lens

The global construction environment offers stakeholders a range of opportunities but is characterised by a high level of risks and uncertainty. Internationalisation is a relatively new field of research in the AEC sector and past research has largely focused on explaining the behaviour of the industry itself. To date there has been little research investigating the client's leadership role. Much effort has been placed on positioning clients towards overall industry performance improvement, however, with little emphasis on the client's capacity to undertake their role. Clients establish the decision-making environment through key early critical decisions including procurement strategy and team membership. To a large extent they establish a unique culture that project team members need to work within and make decisions, which is the social and cultural embedding of the economic activities on projects. This theoretical paper is positioned within a PhD study which undertakes a cultural political economy perspective to investigate the client's central role in setting the boundaries within which decisions affecting budgets, quality, design, project organisational structure and team membership throughout the project lifecycle come to be made. A conceptual model for client leadership on international projects is developed based upon two contextual indicators which seeks to describe and explain the economic decisions clients make, which are deeply embedded in social relationships, shared meanings and cultural norms and the associated power and influence clients have on the political economy of international design and construction practice. This paper also seeks to develop a research question for future empirical testing.

Constructing the conditions of and environments for interdisciplinary research on perception and action

This paper suggests ways in which art processes may contribute to the interdisciplinary study of perception and action and the relationships between body, person, and environment. Artists-turned-architects Arakawa and Gins serve as the most advanced example of an interdisciplinary research project in terms of coordinating material processes with contemporary findings, methods, and orientations from across the arts, humanities, and hard and soft sciences. In the first section of the paper, I discuss Arakawa and Gins's Reversible Destiny Lofts at Mitaka as an example of their procedural approach to long-term sustainable experimental environments. In the second section, the tactics through which Arakawa and Gins have repositioned art for the nonart purposes and common research goals are posited. Finally, I briefly outline the disciplinary positions and research values needed in order to move toward a more inclusive and interdisciplinary research practice.

An empirical examination of feedback : user control and performance in a hapto-audio-visual training environment

Utilising advanced technologies, such as virtual environments (VEs), is of importance to training and education. The need to develop and effectively apply interactive, immersive 3D VEs continues to grow. As with any emerging technology, user acceptance of new software and hardware devices is often difficult to measure and guidelines to introduce and ensure adequate and correct usage of such technologies are lacking. It is therefore imperative to obtain a solid understanding of the important elements that play a role in effective learning through VEs. In particular, 3D VEs may present unusual and varied interaction and adoption considerations. The major contribution of this study is to investigate a complex set of interrelated factors in the relatively new sphere of VEs for training and education. Although many of the factors appears to be important from past research, researcher have not explicitly studied a comprehensive set of inter-dependant, empirically validated factors in order to understand how VEs aid complex procedural knowledge and motor skill learning. By integrating theory from research on training, human computer interaction (HCI), ergonomics and cognitive psychology, this research proposes and validates a model that contributes to application-specific VE efficacy formation. The findings of this study show visual feedback has a significant effect on performance. For tactile/force feedback and auditory feedback, no significant effect were found. For satisfaction, user control is salient for performance. Other factors such as interactivity and system comfort, as well as level of task difficulty, also showed effects on performance.

Comparing and contrasting person-environment fit and misfit

For previous Fit e-Conferences, we have presented various aspects of our research on how person-environment (PE) fit and misfit compare. We have argued that because so little is known about how individuals experience fit and misfit at work, qualitative, exploratory research was called for (Talbot & Billsberry, 2007; 2008). Last year, our e-conference contribution detailed how using causal mapping in PE fit research would enable individuals’ experiences of fit and misfit to be captured and, as well as generating rich idiographic data, would further be amenable to nomothetic analysis (Talbot, Ambrosini & Billsberry, 2009). This paper briefly reviews why we set out to research employees’ fit and misfit perceptions, how we used causal mapping and discusses the main findings from our research.
