Planning for knowledge based urban development in Malaysia : Cyberjaya @ Multimedia Super Corridor

Knowledge based urban development (KBUD) is a new paradigm in urban planning tailoring to the era of knowledge economy. It aims mainly to assist a contemporary city to promote a more sustainable socio-spatial order. The paper reports on the investigation of KBUD initiative in Malaysia which is manifested through the establishment of a project called Multimedia Super Corridor (MSC). MSC Malaysia aims to attract knowledge workers and industries to invest and operate within the area by creating a world class urban corridor with state-of-the-art multimedia infrastructure, efficient transportation system and an attractive living environment. Based on documents analysis and interviews, this paper analyses the strategies, implementations, and achievements of KBUD initiative in Cyberjaya, being the leading intelligent city of the unique Malaysia’s KBUD project-MSC Malaysia. A critical evaluation is made to assess the achievements of MSC, by looking at the physical changes after about ten years since its official launching. The findings recommend some valuable lessons for other cities that strive to develop KBUD strategies, strengthen their sustainable socio-spatial policies, and seek a global recognition.

Knowledge based urban development in classrooms : planning Taipei's knowledge based development

Rapid urbanisation of the global population over the last two centuries has inevitably brought with it a number of challenges and opportunities for economic, environmental and social sustainability of regions. This is arguably a result of rapid globalisation and subsequent growth in knowledge and service based economic markets. This paper reviews the introduction of a specialised teaching structure where the concepts of Knowledge Based Urban Development and Knowledge Cities were taught to various students of the discipline of Urban and Regional Planning at the Queensland University of Technology, through their study tour to the city of Taipei, Taiwan. The concepts were conveyed under the name ‘Taipei Metropolis Knowledge Based Regional Planning Studio’ and its methodology reviewed a series of tasks that was considered to provide a stronger level of understanding of how Knowledge Cities and Knowledge Based Urban Development had been formed in some areas of Taiwan. Findings from this international collaborative planning studio indicate that students have gained a greater level of understanding and insight into planning systems and processes in a trans-cultural context. The students have also been exposed to ideas and knowledge that have challenged conventional perspectives and encouraged global awareness.

Enhancing workplace learning through collaborative HRD

Human resource development (HRD) has evolved a great deal over the past 20 years. Indeed, developments in HRD theory, research and practice have helped transform HRD from a reactive function focusing on administrative and bureaucratic issues to a proactive function focusing on creating learning and development opportunities for employees that not only allow them to achieve their potential but also make a substantial contribution to the longterm survival and sustainability of the organisation. HRD is now seen as an investment in the future of an organisation. This investment perspective is based on the recognition that HRD is linked to business strategy and the achievement of competitive advantage (Caravan et al. 2002). One reason for the shift in emphasis is that many of the traditional sources of competitive advantage (technology, economies of scale) have diminished in value. Nowadays it is the workforce that has come to be seen as an important source of competitive advantage for the organisation. However, not too long ago employees were viewed by management as a disposable resource rather than an asset to an organisation.

Business leadership development in Iran

Throughout the twentieth century the economics of the Middle East rose and fell many times in response to the external environment, including European de-colonization and the US and former USSR competing to provide military and economic aid after World War II. Throughout these upheavals the Middle East has remained internationally significant politically and economically not least for the region's large reserves of oil and gas, as discussed in the Introduction to this volume. In recent decades, Western nations have moved to invest into the Middle East in the rapidly developing technology, tourism and education industries that have proliferated. For its part, Iran has been the world's fourth largest provider of petroleum and second largest provider of natural gas and, despite years of political unrest, has made rapid expansion into information technology and telecommunications. Increased involvement in the global economy has meant that Iran has invested heavily in education and training and moved to modernize its management practices. Hitherto there has been little academic research into management in either Western or local organizations in Iran. This chapter seeks to address that gap in knowledge by exploring business leadership in Iran, with particular reference to cultural and institutional impacts.

CgDN24 : a gene involved in hyphal development in the fungal phytopathogen Colletotrichum gloeosporioides

A cDNA corresponding to a transcript induced in culture by N starvation, was identified in Colletotrichum gloeosporioides by a differential hybridisation strategy. The cDNA comprised 905 bp and predicted a 215 aa protein; the gene encoding the cDNA was termed CgDN24. No function for CgDN24 could be predicted by database homology searches using the cDNA sequence and no homologues were found in the sequenced fungal genomes. Transcripts of CgDN24 were detected in infected leaves of Stylosanthes guianensis at stages of infection that corresponded with symptom development. The CgDN24 gene was disrupted by homologous recombination and this led to reduced radial growth rates and the production of hyphae with a hyperbranching phenotype. Normal sporulation was observed, and following conidial inoculation of S. guianensis, normal disease development was obtained. These results demonstrate that CgDN24 is necessary for normal hyphal development in axenic culture but dispensable for phytopathogenicity. © 2005 Elsevier GmbH. All rights reserved.

Identity development in career-changing beginning teachers : a qualitative study of professional scientists becoming school teachers

This qualitative study provides a critical case to analyse the identity development of professionals who already have a strong sense of identity as scientists and have decided to relinquish their professional careers to become teachers. The study followed a group of professionals who undertook a one-year teacher education course and were assigned to secondary and middle-years schools on graduation. Their experiences were examined through the lens of self-determination theory, which posits that autonomy, confidence and relationships are important in achieving job satisfaction. The findings indicated that those teachers who were able to achieve this sense of autonomy and confidence, and had established strong relationships with colleagues generated a positive professional identity as a teacher. The failure to establish supportive relationships was a decisive event that challenged their capacity to develop a strong sense of identity as a teacher.

Composite SaaS placement and resource optimization in Cloud computing using evolutionary algorithms

Software as a Service (SaaS) is gaining more and more attention from software users and providers recently. This has raised many new challenges to SaaS providers in providing better SaaSes that suit everyone needs at minimum costs. One of the emerging approaches in tackling this challenge is by delivering the SaaS as a composite SaaS. Delivering it in such an approach has a number of benefits, including flexible offering of the SaaS functions and decreased cost of subscription for users. However, this approach also introduces new problems for SaaS resource management in a Cloud data centre. We present the problem of composite SaaS resource management in Cloud data centre, specifically on its initial placement and resource optimization problems aiming at improving the SaaS performance based on its execution time as well as minimizing the resource usage. Our approach differs from existing literature because it addresses the problems resulting from composite SaaS characteristics, where we focus on the SaaS requirements, constraints and interdependencies. The problems are tackled using evolutionary algorithms. Experimental results demonstrate the efficiency and the scalability of the proposed algorithms.

An integrated approach to professional development in secondary schools

Following the implementation of the National Professional Standards for Teachers, all teachers in Australia will be required to undertake 30 hours per year of professional development (PD) to maintain their registration. However, defining what constitutes effective PD is complex and often contested. This paper looks at a case study in Queensland, Australia, where a high school worked collaboratively with a university lecturer to deliver effective whole-school professional development. The lecturer acted as an external change agent, working closely with the principal and staff to build a relationship of trust and to develop a strategy for the delivery of PD on-site. This case highlights how partnerships between teachers and teacher educators combined with a willing school leader can provide positive opportunities for collaborative, sustainable, professional growth and learning.

Resource allocation in multiuser cooperative OFDM system using forced cost based decisions

A sub optimal resource allocation algorithm for Orthogonal Frequency Division Multiplexing (OFDM) based cooperative scheme is proposed. The system consists of multiple relays. Subcarrier space is divided into blocks and relays participating in cooperation are allocated specific blocks to be used with a user. To ensure unique subcarrier assignment system is constrained such that same block cannot be used by more than one user. Users are given fair block assignments while no restriction for maximum number of blocks a relay can employ is given. Forced cost based decisions [1] are used for block allocation. Simulation results show that this scheme outperforms a non cooperating scheme with sequential allocation with respect to power usage.

Sustainable urban infrastructure development in South East Asia : evidence from Hong Kong, Kuala Lumpur and Singapore

Many South East Asian cities have experienced substantial physical, economic and social transformations during the past several decades. The rapid pace of globalization and economic restructuring has resulted in these cities receiving the full impact of urbanization pressures. In an attempt to ease these pressures, cities such as Singapore, Hong Kong and Kuala Lumpur have advocated growth management approaches focusing especially on urban infrastructure sustainability. These approaches aim to achieve triple bottom line sustainability by balancing economic and social development, and environmental protection. This chapter evaluates three Asia-Pacific city cases, Singapore, Hong Kong and Kuala Lumpur, and assesses their experiences in managing their urban forms and infrastructure whilst promoting sustainable patterns of urban development.

Supporting the learning of rapid application development in a database environment

Intelligent Tutoring Systems (ITSs) are computer systems designed to provide individualised help to students, learning in a problem solving context. The difference between an ITS and a Computer Assisted Instruction (CAI) system is that an ITS has a Student Model which allows it to provide a better educational environment. The Student Model contains information on what the student knows, and does not know, about the domain being learnt, as well as other personal characteristics such as preferred learning style. This research has resulted in the design and development of a new ITS: Personal Access Tutor (PAT). PAT is an ITS that helps students to learn Rapid Application Development in a database environment. More specifically, PAT focuses on helping students to learn how to create forms and reports in Microsoft Access. To provide an augmented learning environment, PAT’s architecture is different to most other ITSs. Instead of having a simulation, PAT uses a widelyused database development environment (Microsoft Access). This enables the students to ask for help, while developing real applications using real database software. As part of this research, I designed and created the knowledge base required for PAT. This contains four models: the domain, student, tutoring and exercises models. The Instructional Expert I created for PAT provides individualised help to the students to help them correctly finish each exercise, and also proposes the next exercise that a student should work on. PAT was evaluated by students enrolled in the Databases subject at QUT, and by staff members involved in teaching the subject. The results of the evaluation were positive and are discussed in the thesis.

Comparison of cervical and blood T-cell responses to human papillomavirus-16 in women with human papillomavirus-associated cervical intraepithelial neoplasia

Human papillomaviruses (HPVs) are obligate epithelial pathogens and typically cause localized mucosal infections. We therefore hypothesized that T-cell responses to HPV antigens would be greater at sites of pathology than in the blood. Focusing on HPV-16 because of its association with cervical cancer, the magnitude of HPV-specific T-cell responses at the cervix was compared with those in the peripheral blood by intracellular cytokine staining following direct ex vivo stimulation with both virus-like particles assembled from the major capsid protein L1, and the major HPV oncoprotein, E7. We show that both CD4 + and CD8 + T cells from the cervix responded to the HPV-16 antigens and that interferon-γ (IFN-γ) production was HPV type-specific. Comparing HPV-specific T-cell IFN-γ responses at the cervix with those in the blood, we found that while CD4 + and CD8 + T-cell responses to L1 were significantly correlated between compartments (P = 0.02 and P = 0.05, respectively), IFN-γ responses in both T-cell subsets were significantly greater in magnitude at the cervix than in peripheral blood (P = 0.02 and P = 0.003, respectively). In contrast, both CD4 + and CD8 + T-cell IFN-γ responses to E7 were of similar magnitude in both compartments and CD8 + responses were significantly correlated between these distinct immunological compartments (P = 0.04). We therefore show that inflammatory T-cell responses against L1 (but not E7) demonstrate clear compartmental bias and the magnitude of these responses do reflect local viral replication but that correlation of HPV-specific responses between compartments indicates their linkage.

Human papillomavirus vaccines in plants

Human papillomaviruses are the etiological agents of cervical cancer, one of the two most prevalent cancers in women in developing countries. Currently available prophylactic vaccines are based on the L1 major capsid protein, which forms virus-like particles when expressed in yeast and insect cell lines. Despite their recognized efficacy, there are significant shortcomings: the vaccines are expensive, include only two oncogenic virus types, are delivered via intramuscular injection and require a cold chain. Plant expression systems may provide ways of overcoming some of these problems, in particular the expense. In this article, we report recent promising advances in the production of prophylactic and therapeutic vaccines against human papillomavirus by expression of the relevant antigens in plants, and discuss future prospects for the use of such vaccines. © 2010 Expert Reviews Ltd.
