The development of a generic framework for the implementation of a cheap, component-based virtual video-conferencing system

We address the problem of virtual-videoconferencing. The proposed solution is effected in terms of a generic framework based on an in-house Virtual Reality system. The framework is composed of a number of distinct components: model acquisition, head tracking, expression analysis, network transmission and avatar reconstruction. The framework promises to provide a unique, cheap, and fast system for avatar construction, transmission and animation. This approach affords a conversion from the traditional video stream approach to the management of an avatar remotely and consequently makes minimal demands on network resources.

Evidence-based development of school-based and family-involved prevention of overweight across Europe : the ENERGY-project's design and conceptual framework

Background
There is an urgent need for more carefully developed public health measures in order to curb the obesity epidemic among youth. The overall aim of the "EuropeaN Energy balance Research to prevent excessive weight Gain among Youth" (ENERGY)-project is the development and formative evaluation of a theory-informed and evidence-based multi-component school-based and family-involved intervention program ready to be implemented and evaluated for effectiveness across Europe. This program aims at promoting the adoption or continuation of health behaviors that contribute to a healthy energy balance among school-aged children. Earlier studies have indicated that school and family environments are key determinants of energy-balance behaviors in schoolchildren. Schools are an important setting for health promotion in this age group, but school-based interventions mostly fail to target and involve the family environment.

Methods
Led by a multidisciplinary team of researchers from eleven European countries and supported by a team of Australian experts, the ENERGY-project is informed by the Environmental Research Framework for Weight gain Prevention, and comprises a comprehensive epidemiological analysis including 1) systematic reviews of the literature, 2) secondary analyses of existing data, 3) focus group research, and 4) a cross European school-based survey.

Results and discussion
The theoretical framework and the epidemiological analysis will subsequently inform stepwise intervention development targeting the most relevant energy balance-related behaviors and their personal, family-environmental and school-environmental determinants applying the Intervention Mapping protocol. The intervention scheme will undergo formative and pilot evaluation in five countries. The results of ENERGY will be disseminated among key stakeholders including researchers, policy makers and the general population.

Conclusions
The ENERGY-project is an international, multidisciplinary effort to develop and test an evidence-based and theory-informed intervention program for obesity prevention among school-aged children.

Awareness support in a component-based collaborative environment

The awareness support for activities in collaborative environments is important for effective collaboration and coordination. It helps people know who else is doing what in a shared workspace. The amount of awareness needed varies due to specific roles users undertake during collaboration. While emphasizing the importance of roles, we introduced related research on awareness and a component-based collaboration metamodel. Based on that metamodel, several awareness elements were discussed and implemented in a collaborative environment LiveNet4. Model view controller pattern used to construct the Web-based interface of LiveNet4 was also introduced at the end of this paper.

Analysis of cultural conflict in the development of web-enabled information systems

The advent of the World Wide Web (WWW) and the emergence of Internet commerce have given rise to the web as a medium of information exchange. In recent years, the phenomenon has affected the realm of transaction processing systems, as organizations are moving from designing web pages for marketing purposes, to web-based applications that support business-to-business (WEB) and business-to-consumer (B2C) interactions, integrated with databases and other back-end systems (Isakowitz, Bieber et al., 1998). Furthermore, web-enabled applications are increasingly being used to facilitate transactions even between various business units within a single enterprise. Examples of some of the more popular web-enabled applications in use today include airline reservation systems, internet banking, student enrollment systems in universities, and Human Resource (HR) and payroll systems. The prime motive behind the adoption of web-enabled applications are productivity gains due to reduced processing time, decrease in the usage of paper-based documentation and conventional modes of communication (such as letters, fax, or telephone), and improved quality of services to clients. Indeed, web-based solutions are commonly referred to as customer-centric (Li, 2000), which means that they provide user interfaces that do not necessitate high level of computer proficiency. Thus, organizations implement such systems to streamline routine transactions and gain strategic benefits in the process (Nambisan & Wang, 1999), though the latter are to be expected in the long-term. Notwithstanding the benefits of web technology adoption, the web has ample share of challenges for initiators and developers. Many of these challenges are associated with the unique nature of web-enabled applications. Research in the area of web-enabled information systems has revealed several differences with traditional applications. These differences exist with regards to system development methodology, stakeholder involvement, tasks, and technology (Nazareth, 1998). According to Fraternali (1999), web applications are commonly developed using an evolutionary prototyping approach, whereby the simplified version of the application is deployed as a pilot first, in order to gather user feedback. Thus, web-enabled applications typically undergo continuous refinement and evolution (Ginige, 1998; Nazareth, 1998; Siau, 1998; Standing, 2001). Prototype-based development also leads web-enabled information systems to have much shorter development life cycles, but which, unlike traditional applications, are regrettably developed in a rather adhoc fashion (Carstensen & Vogelsang, 2001). However, the principal difference between the two kinds of applications lies in the broad and diverse group of stakeholders associated with web-based information systems (Gordijn, Akkermans, et al., 2000; Russo, 2000; Earl & Khan, 2001; Carter, 2002; Hasselbring, 2002; Standing, 2002; Stevens & Timbrell, 2002). Stakeholders, or organizational members participating in a common business process (Freeman, 1984), vary in their computer competency, business knowledge, language and culture. This diversity is capable of causing conflict between different stakeholder groups with regards to the establishment of system requirements (Pouloudi & Whitley, 1997; Stevens & Timbrell, 2002). Since, web-based systems transcend organizational, departmental, and even national boundaries, the issue of culture poses a significant challenge to the web systems’ initiators and developers (Miles & Snow, 1992; Kumar & van Dissel, 1996; Pouloudi & Whitley, 1996; Li & Williams, 1999).

Cultural heritage and development in South East Asia

This chapter discusses research undertaken into the developmental role of museums and heritage sites in Thailand and the Greater Mekong Subregion, a geographical area that also includes Cambodia, Laos PDR and Myanmar. It contextualizes an international project, the Lampang Temples Project, to explore the potential role that museums and heritage sites can play in place-based development work, particularly in an Asian context where sacred places are simultaneously valued by local members of the community and as desinations for religious pilgrims and international tourists. The discussion of the Lampang Temples Project is located within an understanding of the international discourse concerning the roles of museums in development, including those contributions to the discourse that have originated in the Asia-Pacific region. It is also situated within an understanding of the roles of international agencies and local governments in the promotion of programmes and infrastructure for the preservation of Buddhist heritage and the relationship of this development strategy with tourism. Furthermore, due to the participatory and observational experience of the authors in the Lampang Temples Project, the chapter also considers the issues involved in applying cross-cultural pedagogies to the management of cultural tourism sites, including UNESCO World Heritage Sites. The results of the Lampang Temples Project support the contention that colaborative training models and pedagogies can be adapted, provided that differing cultural contexts and suppositions are appropriately articulated and integrated. Further, it suggests that this type of collaborative approach to the management of cultural tourism sites has the potential to play an important role in Buddhist heritage development processes.

Development amidst communal conflict: case study of a Christian FBO in a Buddhist–Muslim conflict region in Myanmar

Faith can be a powerful force for positive development and social change, but as James (2011) notes, it is a highly flammable fuel that can also easily result in negative outcomes. The pervasive influence of religion in the lives of many gives it a unique ability to shape both individual and communal identities (perceptions of self and others). While religious identities can be an extremely positive force, they can also be used as a source for exclusive and intolerant attitudes, with a potential to feed nationalisms that become motivators or justifications for conflict. This is particularly true in tense multi-religious contexts where competing ethnoreligious nationalistic identities and historical claims are forced to coexist – especially for faith-based development agencies that relate to one of those identities.This chapter explores the work of a small local Christian faith-based organisation (FBO) working in Buddhist communities in a region of significant Buddhist–Muslim tension and recent violent communal conflict, as a case study of development across complex faith boundaries. Local FBO Bethel works in partnership with the international FBO GraceWorks Myanmar (GWM). Making this case particularly interesting, Bethel has evolved out of a related religious organisation that still maintains a mandate for preaching a contextual Christian message to Buddhists, and most of the local workers are converts from Buddhism. Given the most inflammatory religious sparks for worsening conflicts are widely regarded to be discriminatory practices and proselytism – or perceptions of proselytism (e.g. Clarke and Jennings 2008; Flanigan 2010) – this case study is interesting for the way these issues are handled. This chapter includes new research examining whether and how this FBO has been able to avoid inflaming tensions and has been broadly granted a social mandate to operate in Buddhist communities, even though it constitutes a third religious actor in a context of vitriolic interreligious conflict.

Managing collaborative business process in knowledge-intensive environment

Business processes especially those in knowledge intensive environments often emerge rather than following predefined steps. Supporting emergent processes is one of the key issues for collaborative knowledge sharing. This paper first introduces a component-based workspace metamodel used to support emergent processes. A loose-coupled collaborative process management model WorkPath is proposed based on the workspace structure to support flexible process evolution management and coordination among processes. Key elements that construct workspace and WorkPath, such as role, action, artifact, workspace and reference relation, are described in detail. An implementation prototype and future work is also discussed at the end of the paper.

Continuous improvement through shared understanding : reconceptualising instructional design for online learning

Many Australian tertiary institutions provide support for academic staff in the design and development of online teaching and learning resources, often employing a centralised unit staffed with educational and instructional designers, multimedia and online developers, audio/video producers and graphic artists. It is not unusual for these units to have evolved from print-based distance education providers and consequently the design and development processes inherent within those units are often steeped in ‘traditional’ sequential instructional development models. We argue that these models are no longer valid for effectively working with academic staff given the dynamic nature of online learning environments and the diversity of skills to implement effective online learning. This paper therefore presents an extended instructional design model in which the development cycle for online teaching and learning materials uses a scaffolding strategy in order to cater for learner-centred activities and to maximise scarce developer and academic resources. The model also integrates accepted phases of the instructional development process to provide guidelines for the disposition of staff and to more accurately reflect the creation of resources as learning design rather than instructional design. It is a model that builds on instructional design processes and integrates concepts of team-based development, shared understanding and the development of relevant communities of practice.

Constitutionalism, good faith and the doctrine of specific performance: rights, duties and equitable discretion

This article will explore the European roots of the doctrine of specific performance and the influence of transformative constitutionalism on these in recent times. The question whether specific performance is available as of right (as in the civil law), or only subject to judicial discretion (as in the common law), will be investigated. The demonstrated impact of constitutional rights on contract law in the mixed system of South Africa will be contrasted with developments in English and Australian contract law, where the common-law rules are more deeply entrenched and the potential scope for human rights-based development of these is arguably smaller, though still important. The article will argue, using comparative rules on specific performance as an example, that the concept of a duty of good faith or contractual fairness is likely to play a greater role in future in all three of the countries under consideration, reducing the common/civil/mixed legal systems divide.

The origin of "Rare Earth" texture development in extruded Mg-based alloys and its effect on tensile ductility

The extrusion behaviour, texture and tensile ductility of five binary Mg-based alloys have been examined and compared to pure Mg. The five alloying additions examined were Al, Sn, Ca, La and Gd. When these alloys are compared at equivalent grain size, the La- and Gd-containing alloys show the best ductilities. This has been attributed to a weaker extrusion texture. These two alloying additions, La and Gd, were found to also produce a new texture peak with View the MathML source parallel to the extrusion direction. This “rare earth texture” component was found to be suppressed at high extrusion temperatures. It is proposed that the View the MathML source texture component arises from oriented nucleation at shear bands.

The development of a network for community based obesity prevention : the CO-OPS collaboration

Background: Community-based interventions are a promising approach and an important component of a comprehensive response to obesity. In this paper we describe the Collaboration of COmmunity-based Obesity Prevention Sites (CO-OPS Collaboration) in Australia as an example of a collaborative network to enhance the quality and quantity of obesity prevention action at the community level. The core aims of the CO-OPS Collaboration are to: identify and analyse the lessons learned from a range of community-based initiatives aimed at tackling obesity, and; to identify the elements that make community-based obesity prevention initiatives successful and share the knowledge gained with other communities.
Methods: Key activities of the collaboration to date have included the development of a set of Best Practice Principles and knowledge translation and exchange activities to promote the application (or use) of evidence, evaluation and analysis in practice.
Results: The establishment of the CO-OPS Collaboration is a significant step toward strengthening action in this area, by bringing together research, practice and policy expertise to promote best practice, high quality evaluation and knowledge translation and exchange. Future development of the network should include facilitation of further
evidence generation and translation drawing from process, impact and outcome evaluation of existing communitybased interventions.
Conclusions: The lessons presented in this paper may help other networks like CO-OPS as they emerge around the globe. It is important that networks integrate with each other and share the experience of creating these networks.

Evaluation of community participation for the development of culture-based fisheries in village reservoirs of Sri Lanka

In this paper, an attempt is made to identify the socioeconomic characteristics of a community that influence the development and management of culture-based fisheries in village reservoirs of Sri Lanka. Socioeconomic data were collected from 46 agricultural farming communities associated with 47 village reservoirs in Sri Lanka. Principal component analysis indicated that scores of the first principal component were positively influenced by socioeconomic characteristics that are favorable for making collective decisions. These included leadership of the officers, age of the group, percentage of active members of the group, percentage of kinship of the group, percentage of common interest of the group, and percentage of participation of the group. The size of the group had a negative effect on the first principal component. The principal component scores of communities were positively related to willingness to pay (P < 0.001). The communities with socioeconomic characteristics favoring collective decision making were in favor of culture-based fisheries. Homogeneity of group characteristics facilitated successful development of culture-based fisheries.

Iterative development of Stand Up Australia : a multi-component intervention to reduce workplace sitting

Sitting, particularly in prolonged, unbroken bouts, is widespread within the office workplace, yet few interventions have addressed this newly-identified health risk behaviour. This paper describes the iterative development process and resulting intervention procedures for the Stand Up Australia research program focusing on a multi-component workplace intervention to reduce sitting time. The development of Stand Up Australia followed three phases. 1) Conceptualisation: Stand Up Australia was based on social cognitive theory and social ecological model components. These were operationalised via a taxonomy of intervention strategies and designed to target multiple levels of influence including: organisational structures (e.g. via management consultation), the physical work environment (via provision of height-adjustable workstations), and individual employees (e.g. via face-to-face coaching). 2) Formative research: Intervention components were separately tested for their feasibility and acceptability. 3) Pilot studies: Stand Up Comcare tested the integrated intervention elements in a controlled pilot study examining efficacy, feasibility and acceptability. Stand Up UQ examined the additional value of the organisational- and individual-level components over height-adjustable workstations only in a three-arm controlled trial. In both pilot studies, office workers’ sitting time was measured objectively using activPAL3 devices and the intervention was refined based on qualitative feedback from managers and employees. Results and feedback from participants and managers involved in the intervention development phases suggest high efficacy, acceptance, and feasibility of all intervention components. The final version of the Stand Up Australia intervention includes strategies at the organisational (senior management consultation, representatives consultation workshop, team champions, staff information and brainstorming session with information booklet, and supportive emails from managers to staff), environmental (height-adjustable workstations), and individual level (face-to-face coaching session and telephone support). Stand Up Australia is currently being evaluated in the context of a cluster-randomised controlled trial at the Department of Human Services (DHS) in Melbourne, Australia. Stand Up Australia is an evidence-guided and systematically developed workplace intervention targeting reductions in office workers’ sitting time.
