Information and communication technologies are thought by some to offer a new solution to world poverty.
It is argued that information and communication technologies (ICT) allow poor countries to ‘leap-frog’
traditional stages of development and become immediately engaged with the ‘new economy’. Such an
optimistic view requires appropriate government policies to facilitate this shift. Interventions required
would include improving access levels and quality of telecommunication and electricity infrastructure,
improved quality of education and numbers of those accessing education, and providing both direct
and indirect support to encourage local firms to become engaged with the global economy. Ironically,
these policies are consistent with current orthodox development policies currently pursued within the
‘traditional’ economy. This chapter therefore considers what exactly is new about ICT in terms of its
potential impact on the poor.

The desire to reduce carbon emissions due to transportation sources has led over the past decade to the development of new propulsion technologies, focused on vehicle electrification (including hybrid, plug-in hybrid and battery electric vehicles). These propulsion technologies, along with advances in telecommunication and computing power, have the potential of making passenger and commercial vehicles more energy efficient and environment friendly. In particular, energy management algorithms are an integral part of plug-in vehicles and are very important for achieving the performance benefits. The optimal performance of energy management algorithms depends strongly on the ability to forecast energy demand from the vehicle. Information available about environment (temperature, humidity, wind, road grade, etc.) and traffic (traffic density, traffic lights, etc.), is very important in operating a vehicle at optimal efficiency. This article outlines some current technologies that can help achieving this optimum efficiency goal. In addition to information available from telematic and geographical information systems, knowledge of projected vehicle charging demand on the power grid is necessary to build an intelligent energy management controller for future plug-in hybrid and electric vehicles. The impact of charging millions of vehicles from the power grid could be significant, in the form of increased loading of power plants, transmission and distribution lines, emissions and economics (information are given and discussed for the US case). Therefore, this effect should be considered in an intelligent way by controlling/scheduling the charging through a communication based distributed control.

The current global economic instability and the vulnerability of small nations provide the impetus for greater integration between the countries of the South Pacific region. This exercise is critical for their survival. Past efforts of regional integration in the South Pacific have mostly failed. However, today’s IT collaborative capabilities provide the opportunity to develop a shared IT infrastructure to facilitate integration in the South Pacific. In developing an IT-backed model of regional integration, this study identifies and reports on the antecedents of the current stage for integration in the Pacific. We conducted interviews with twenty five individuals from various sectors and find that while most respondents were optimistic about the potential of IT-backed regional integration, significant challenges exists. The study identifies and discusses these challenges providing policy implications to stakeholders in the regional integration process. The findings will assist in suggesting a model of regional integration 2.0 for the Pacific region.

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.

Purpose : The aim of this study was to examine the factorial and criterion validity of the Neighborhood Environment Walkability Scale (NEWS) and to develop an abbreviated version (NEWS-A).

Methods : A stratified two-stage cluster sample design was used to recruit 1286 adults. The sample was drawn from residential addresses within eight high- and eight low-walkable neighborhoods matched for socioeconomic status. Subjects completed the NEWS and reported weekly minutes of walking for transport and recreation using items from the International Physical Activity Questionnaire.

Results : Multilevel confirmatory factor analysis was used to develop measurement models of the NEWS and NEWS-A. Six individual-level and five blockgroup-level factors were identified. Factors/scales gauging presence of diversity of destinations, residential density, walking infrastructure, aesthetics, traffic safety, and crime were positively related to walking for transport. Aesthetics, mixed destinations, and residential density were associated with walking for recreation.

Conclusions : The NEWS and NEWS-A possess adequate levels of factorial and criterion validity. Alternative methods of scoring for different purposes are presented.

Objective
The Australian lifestyle intervention program Life! is only the second reported, large-scale diabetes prevention program. This paper describes the genesis and the successful establishment of Life! and its key outcomes for participants and implementation.

Research
Design and Methods Life!, a behavior change intervention, comprises six group sessions over eight months. The Victorian Department of Health funded Diabetes Australia-Victoria to implement the program. Experience of the Greater Green Triangle diabetes prevention implementation trial was used for intervention design, workforce development, training and infrastructure. Clinical and anthropometric data from participants, used for program evaluation, was recorded on a central database.

Results
Life! has a state-wide workforce of 302 trained facilitators within 137 organizations. 29,000 Victorians showed interest in Life! and 15,000 individuals have been referred to the program. In total, 8,412 participants commenced a Life! program between October 2007 and June 2011. 37% of the original participants completed the eight month program. Participants completing sessions one to five lost an average of 1·4 kg weight (p<0·001) and waist circumference of 2·5cm (p<0.001). Those completing six sessions lost an average of 2·4 kg weight (p<0·001) and waist circumference of 3·8 cm (p<0·001). The weight loss of 2.4 kg represents 2.7% of participants’ starting body weight.

Conclusion
The impact of Life! is attributable to applying available evidence for the systems design of the intervention, and collaboration between policy makers, implementers and evaluators using the principles of continuous quality improvement to support successful, large scale recruitment and implementation.

Human-induced changes to habitats can have deleterious effects on many species that occupy them. However, some species can adapt and even benefit from such modifications. Artificial reefs have long been used to provide habitat for invertebrate communities and promote local fish populations. With the increasing demand for energy resources within ocean systems, there has been an expansion of infrastructure in near-shore benthic environments which function as de facto artificial reefs. Little is known of their use by marine mammals. In this study, the influence of anthropogenic sea floor structures (pipelines, cable routes, wells and shipwrecks) on the foraging locations of 36 adult female Australian fur seals (Arctocephalus pusillus doriferus) was investigated. For 9 (25%) of the individuals, distance to anthropogenic sea floor structures was the most important factor in determining the location of intensive foraging activity. Whereas the influence of anthropogenic sea floor structures on foraging locations was not related to age and mass, it was positively related to flipper length/standard length (a factor which can affect manoeuvrability). A total of 26 (72%) individuals tracked with GPS were recorded spending time in the vicinity of structures (from <1% to >75% of the foraging trip duration) with pipelines and cable routes being the most frequented. No relationships were found between the amount of time spent frequenting anthropogenic structures and individual characteristics. More than a third (35%) of animals foraging near anthropogenic sea floor structures visited more than one type of structure. These results further highlight potentially beneficial ecological outcomes of marine industrial development.

Increased global demand for agricultural production is being driven, in particular, by the rising middle class in the Asia-Pacific geo-region. The significant role of natural resource-based industries, especially agriculture, in the development of non-metropolitan regions is again being recognised. In this context, this article describes a spatial analysis approach to agricultural development based on the development of Production Areas (PAs) in regional/rural economies. PAs are spatial units within regions selected for the intensive sustainable development of agriculture (including forestry, agro-forestry and bio-energy), their associated activities and underpinning infrastructure. A case study in a resource-based region in Australia—Gippsland – explains the approach. This is informed by the eco-economy model of endogenous regional/rural development, which addresses the links between novel co-production and consumption networks. The methodology for the identification and analysis of PAs has, at its core, Land Suitability Analyses of those agricultural commodities currently cultivated in the region and those that could be grown in future climates. The use of GIS enables us to overlay and analyse several constraints (e.g. flood erosion and salinity risk) and resources (e.g. water and transport) to define PAs and the available land within each of them. The approach is further illustrated by focusing in one PA—Macalister, an irrigated dairy production area where recent dry climatic conditions caused a substantial decline in water resources. Key elements for the sustainable development of this PA are outlined including construction of Blue-Green Infrastructure. Comments on the approach and the need for strategic long-term planning concludes the article.

There has been a resurgence in activity by non-traditional donors (NTDs) since 2000. These flows of foreign development assistance (FDA) are a reflection of the global shift in production and income towards semi-peripheral economies, above all the People’s Republic of China (PRC). The PRC has also adopted its “peaceful rise” and “non-interference” policies with a strong emphasis on South-South cooperation. Some even foresee these changes as opening the space for more public-investment focused development policies, with NTDs providing ready access to capital with few conditionalities. Little attention, however, has been focused how these changes are already impacting in Southeast Asia. The PRC has now become the second largest source of FDA in the Philippines, funding major rail and other infrastructure projects and this trend is set to continue. The experience so far, however, suggests that the Philippine “soggy state” – where the state lacks autonomy from elite classes and processes that hinder development processes - has meant little benefit has accrued from the availability of concessional finance. Despite the rhetoric of “non-interference” in PRC policy, there is evidence that these FDA flows may indeed be aggravating processes of social and political exclusion.

Energy and communication infrastructure for disaster resilience in rural and regional Australia, Regional Studies. Australia's rural and regional areas are prone to frequent natural disasters with extensive socio-economic impacts. Resultant damage to large-grid energy and communication networks can lead to widespread, lengthy outages, signalling the need for alternative infrastructure developments to aid disaster risk reduction and resilience-building (DRRR). Distributed smart renewable energy micro-grid systems can mitigate adverse impacts through outage prevention and rapid service restoration, increase rural and regional resilience, and offer communities opportunities for socio-economic development. However, renewable energy and digital communications policy uncertainty currently adversely affects disaster preparedness and investment in alternative infrastructure, undermining rural and regional futures.

Advanced connectivity offers rural communities prospects for socio-economic development. Despite Australia’s national broadband infrastructure plans, inferior availability and quality of rural Internet connections remain persistent issues. This article examines the impact of limited connectivity on rural socio-economic opportunities, drawing from the views of twelve citizens from the Boorowa local government area in New South Wales. The available fixed wireless and satellite connections in Boorowa are slow and unreliable, and remote regions in the municipality are still without any Internet access. Participants identified four key areas in their everyday lives that are impacted by insufficient connectivity: business development, education, emergency communication, and health. Rural citizens often already face challenges in these areas, and infrastructure advancements in urban spaces can exacerbate rural-urban disparities. Participants’ comments demonstrated apprehension that failure to improve connectivity would result in adverse long-term consequences for the municipality. This article suggests that current broadband policy frameworks require strategic adaptations to account for the socio-economic and geographic contexts of rural communities. In order to narrow Australia’s rural-urban digital divide, infrastructure developments should be prioritised in the most underserved regions.

The Pacific island state of Vanuatu has been considerably shaped by its Christian heritage. Indeed, the role of the various Christian Churches has been pivotal in the development and sustenance of Vanuatu prior to and since its Independence. These Churches include Anglican, Catholic, Pentecostal and evangelical denominations. Missionaries and later local Church leaders were involved directly in Independence movements and shaped the legal and social infrastructure of this nation. This involvement and influence has continued to the present. This article will consider the role the Church has played in the development of Vanuatu. First, a case study analysis of both the historical and contemporary role the Church has played in the development of Vanuatu will be presented. This review will consider the impact of both key individual Church leaders who played central roles in Vanuatu’s Independence. Secondly, the paper will consider the contemporary role Christian Churches play in the provision of social service- including education and health-across Vanuatu. It will conclude that Christianity has therefore played and continues to play a central role in the political and social development of Vanuatu.
