Road infrastructure vulnerability to groundwater table variation due to sea level rise

This study was conducted to assess the vulnerability of coastal road infrastructures due to climate change induced sea level rise and extreme weather conditions through the estimation of road subgrade strength reduction as a result of changes in soil moisture content. The study area located in the Gold Coast, Australia highlighted that the risk is significant. In wet seasons or areas with wet condition, the groundwater table is already high, so even a small change in the groundwater table can raise the risk of inundation; particularly, in areas with existing shallow groundwater. The predicted risk of a high groundwater table on road infrastructure is a long-term hazard. Therefore, there is time to undertake some management plans to decrease the possible risks, for instance, some deep root plants could be planted along the roads with a high level of risk, to decrease the groundwater table elevation.

'Not a Local Win': Rural Australian perceptions of the sustainable impacts of forest plantations

Australian forestry plantations have doubled in the past 15 years, with rural communities harbouring a diverse range of positive and negative of economic, environmental and social impacts – the so-called triple bottom line (TBL). Utilising two Australian rural communities in Eden/Gippsland and Tasmania as qualitative case studies, this research explores how 23 non-forestry affiliated rural residents perceived and experienced the TBL economic, environmental and social impacts of plantation forestry. Residents criticised the economic plantation forestry benefits because of lengthy periods of inactivity and limited local employment, explaining that their community was reliant on the industry yet the promised economic benefits had never fully materialised. There was a sense the industry ‘plant and walk away.’ Residents were concerned about the environment impact on water quality, water tables and fire hazards, although they praised plantation forestry for carbon sequestering, eradicating erosion and water run-off. Negative social impacts were described, specifically how the land-use change from farming to forestry had significantly reduced the local population, employment and need for services. Natural resource management and communication strategies are offered, derived from non-forestry affiliated rural resident perspectives on how best to ensure sustainable forest development in their community.

The determinants of multinational contractors' willingness to bid for Australian public sector major infrastructure projects : deploying the eclectic paradigm of internationalisation

Based on Dunning's dominant international business theory and the unique characteristics of construction, a novel framework is developed and tested to explain multinational contracting into Australia. Beyond contributions to theory, Australian governments now have clear evidence upon which to develop more effective procurement reform towards increasing the attractiveness of public sector major infrastructure projects and competition in this sector.

Revisiting the adoption of innovative products on Australian road infrastructure projects

Construction product innovation can exert a positive influence on project and industry performance. However, guidance is scarce on product innovation diffusion for road infrastructure, in contrast to the large body of literature on the manufacturing industry. A conceptual framework is proposed to understand these processes. Advice is given to managers based on the framework and a large quantitative survey. The framework focuses on contextual characteristics that influence the decision to adopt new-to-industry product innovation, as part of a diffusion process. Case study data are interpreted within the revised framework to test its value and disaggregate the broad obstacles to innovation. A large quantitative survey was then conducted to rank the relative importance of the obstacles constraining the adoption of innovative products on road construction projects. The three most important obstacles were found to be: (1) overemphasis on up-front project costs during tender stage; (2) disagreement over who carries the risk of new product failure; and (3) adversarial contract relations. The results suggest refinements to the conceptual framework to make it a more powerful tool for categorizing and analysing construction innovation obstacles. Results also suggest well-resourced repeat interactions within complementary procurement and regulatory systems will enhance the project teams’ ability to recognize and address innovation obstacles. Further, improved relationships are expected to decrease the need for an overly conservative approach to product approval and prescriptive specifications.

Herpes simplex 2 risk among women in a polygynous setting in rural West Africa

OBJECTIVES: To determine risk factors for herpes simplex 2 (HSV2) infection in women in a polygynous rural Gambian population. METHODS: Data from women who participated in a cross-sectional survey of reproductive health were matched to their own and, for women who had been or were married (ever-married), their spouses' data collected in a cross-sectional survey of fertility interests, including information on marital histories. RESULTS: Data were available on 150 never-married and 525 ever-married women. HSV2 prevalence was 16% amongst never-married women and 36% amongst ever-married women. For ever-married women, their own personal characteristics (age, ethnicity and genital cutting status) and events from their husbands' marriage history were important determinants of HSV2 infection. Women whose husbands married for the first time over age 35 were at greater risk than women whose husbands married by age 24 [odds ratio (OR) 2.72, 95% confidence interval (CI) 1.20-6.10]. Women whose husband reported interest in a new marriage were more likely to be HSV2 positive (OR 1.91, 95% CI 1.18-3.09). Women whose husbands were currently monogamous but had had previous marriages (OR 2.76, 95% CI 1.30-5.88) and women in currently polygynous marriages (OR 2.88, 95% CI 1.66-5.01) were three times as likely to be HSV2 positive as women who were their husband's only wife ever. CONCLUSION: Much transmission of HSV2 in this setting occurs within marriage where opportunity for personal protection is limited. High levels of transmission within marriage may undermine the impact of sexual behaviour change programmes aiming to reduce HSV2 and HIV incidence and complicate their evaluation.

Willingness-to-pay for infrastructure investments for alternative fuel vehicles

This study investigates potential demand for infrastructure investment for alternative fuel vehicles by applying stated preference methods to a Japanese sample. The potential demand is estimated on the basis of how much people are willing to pay for alternative fuel vehicles under various refueling scenarios. Using the estimated parameters, the economic efficiency of establishing battery-exchange stations for electric vehicles is examined. The results indicate that infrastructural development of battery-exchange stations can be efficient when electric vehicle sales exceed 5.63% of all new vehicle sales. Further, we find a complementary relationship between the cruising ranges of alternative fuel vehicles and the infrastructure established.

E-government policies for broadband adoption : the case of the UK Government

Broadband technology has been introduced to the business community and the public as a fast and easy way of exploiting the Internet. The benefits of its use (fast reliable connections, always on) have been widely realised and broadband diffusion is one of the items at the top of the agenda for technology related polices of governments worldwide. Broadband diffusion and capacity development are central to debates in many countries concerning the role of the government in developing efficient broadband policies particularly in terms of the usage of public money. In this paper we examine the impact of government polices to broadband adoption in the case of the UK government, a country that is striving to have the most extensive and competitive broadband market in the G7 by 2005. We analyse specific institutional actions related to IT diffusion as pursued by the government with the view to identify best practices in government intervention. We believe that are our analysis is useful for broadband strategies in particular and technology in general when applied elsewhere.

Facilitators of expanded and extended scope of paramedic practice - what makes them work?

Introduction Better integration of health services and redefinition of health workforce roles through expanding and extending traditional scope of clinical practice have been explored nationally and internationally. This paper aims to extend our earlier work by examining models of expanded and extended scope of paramedic practice for attributes which facilitate such a practice. Methods An exploratory multi-case study analysis of Australia, New Zealand, Canada and the United Kingdom expanded and extended paramedic practices were analysed. Results Successful models of advanced practice harness the capacity and personality of the paramedic practitioner, and are supported by enabling infrastructures, specifically: professional development/ education; clinical guideline and policy (boundary); access to physical infrastructure and clinical support from senior medical practitioners; and, ability to directly refer to other health services (service integration). The scope of advanced practice is however influenced by individual employers’ capacity, perceived needs and preference/ prioritises. The potential for advanced paramedic practice is equally applicable to urban as well as rural Australia. The Council of Ambulance Authorities’ Professional Competency Standard provides the form and functions for building on advanced paramedic practice. Recognition of such advanced paramedic practice provides a structure for professional growth, process for career progression and will support workforce retention. Conclusion The achievement of advanced knowledge and skills has positioned the paramedic profession to be recognized as a valuable clinician. The Council of Ambulance Authorities’ Professional Competency Standards provides the form and function for supporting advanced paramedic practice.

Reforming the procurement of construction and financing of Australian infrastructure : advancing capacity, competition and investment

Funded by an Australian Research Council (ARC) Linkage grant over four years (2009–13), the Major Infrastructure Procurement project sought to find more effective and efficient ways of procuring and delivering the nation’s social and economic infrastructure by investigating constraints relating to construction capacity, competition, and finance in new public sector major infrastructure.1 The research team comprised researchers in construction economics and finance from Queensland University of Technology (QUT), Griffith University (GU), The University of Hong Kong (UHK), and The University of Newcastle (UoN). Project partners included state government departments and agencies responsible for infrastructure procurement and delivery from all Australian mainland states, and private sector companies and peak bodies in the infrastructure sector (see “Introduction” for complete list). There are a number of major outcomes from this research project. The first of these is a scientifically developed decisionmaking model for procurement of infrastructure that deploys a novel and state-of-the-art integration of dominant microeconomic theory (including theories developed by two Nobel Prize winners). The model has been established through empirical testing and substantial experiential evidence as a valid and reliable guide to configuring procurement of new major and mega infrastructure projects in pursuance of superior Valuefor- Money (VfM). The model specifically addresses issues of project size, bundling of contracts, and exchange relationships. In so doing, the model determines the suitability of adopting a Public-Private Partnership (PPP) mode.

Islamic project financing in Indonesian infrastructure development

It is reasonable to expect that Islamic project financing may be a suitable option of infrastructure financing in Indonesia. This research explored the conditions necessary for the implementation of Islamic project financing for Indonesian infrastructure development. It is important that all infrastructure project stakeholders understand the concept comprehensively. This study identified reforms through which the government could more directly support the implementation of Islamic project financing. This research has led to the realisation that Islamic project financing can be implemented in all sectors, in both public and private sector domains, and across Muslim and non-Muslim communities.
