The challenges arising from climate change consequences are likely to impact upon states and other international actors in ways that present new manifestations and dynamics of globalisation. Climate change issues are creating political, economic and social challenges for the international political community, key economic actors, and states, and seem set to alter many dimensions of human social organisation. In the 21st century, climate change is set to create unprecedented global challenges, highlighting inequities and inequalities in functional and material capabilities, and revealing more fully the limits of both domestic and international legal capacities. It is, therefore, timely to engage with some of the international political dimensions of global climate change, including the manner in which it raises new questions regarding the nature of rights and responsibilities and their distribution. There can be little doubt that climate change impacts would be experienced quite differently if the contemporary world was not characterised by global communication and knowledge sharing networks and complex patterns of internationalised trade, production and security. This paper examines the pressing imperatives of responding to climate change consequences by utilising these characteristics of 20th century globalisation to generate new and more effective means of accommodating diverse rights, responsibilities and interests.

Ever seeking to increase returns at a given or lower risk levels , investors are finding that globalization and market integration are making it more difficult to achieve their targets by diversifying their portfolios across nations. Australia moved from being a poor investment prospect in the last third of the 20th Century to becoming fourth in world competitiveness. In contrast, the New Zealand economy has become ever more dependent on volatile agricultural commodities and faces serious infrastructure issues that may hinder its efforts to enhance or even retain its competitiveness. This paper projects from the recent history of the Australian and New Zealand economies to consider how they are likely to fare in resolving the early 21st Century challenges of globalization and demography and asks if Australian investors should consider investing closer to home.

"The topology of a network (such as a telecommunications, multiprocessor, or local area network, to name just a few) is usually modelled by a graph in which vertices represent 'nodes' (stations or processors) while undirected or directed edges stand for 'links' or other types of connections, physical or virtual. A cycle that contains every vertex of a graph is called a hamiltonian cycle and a graph which contains a hamiltonian cycle is called a hamiltonian graph. The problem of the existence of a hamiltonian cycle is closely related to the well known problem of a travelling salesman. These problems are NP-complete and NP-hard, respectively. While some necessary and sufficient conditions are known, to date, no practical characterization of hamiltonian graphs has been found. There are several ways to generalize the notion of a hamiltonian cycle. In this thesis we make original contributions in two of them, namely k-walks and r-trestles." --Abstract.

The Moore bound for a directed graph of maximum out-degree d and diameter k is Md,k=1+d+d2++dk. It is known that digraphs of order Md,k (Moore digraphs) do not exist for d>1 and k>1. Similarly, the Moore bound for an undirected graph of maximum degree d and diameter k is . Undirected Moore graphs only exist in a small number of cases. Mixed (or partially directed) Moore graphs generalize both undirected and directed Moore graphs. In this paper, we shall show that all known mixed Moore graphs of diameter k=2 are unique and that mixed Moore graphs of diameter k3 do not exist.

In Australia, we are facing a period of mental health reform with the establishment of federally funded community youth services in rural areas of the country. These new services have great potential to improve the mental health of rural adolescents. In the context of this new initiative, we have four main objectives with this article. First, we consider the notion of social capital in relation to mental health and reflect on the collective characteristics of rural communities. Second, we review lessons learned from two large community development projects targeting youth mental health. Third, we suggest ways in which the social capital of rural communities might be harnessed for the benefit of youth mental health by using asset-based community development strategies and fourth, we consider the role that rural clinicians might play in this process.

Microarrays are able to measure the patterns of expression of thousands of genes in a genometo give profiles that faciliate much faster analysis of biological process for diagnosis, prognosis and tailored drug discovery. Microarrays, however commonly have missing values, various algorithms have been proposed including Collateral Missing Value Estimation (CMVE), Bayesian Principal Component Analysis (BPCA), Least Square Impute (LSImpute). Local Least Square Impute (LLSImpute) and K-Nearest Neighbour (KNN).

Global statistics of HIV/AIDS infection reveals the disastrous effects of discrimination against women in the area of human health. Women’s vulnerability to HIV/AIDS reflects their wider social, economic and sexual disadvantages compared to their male counterpart. Although the gender context of HIV/AIDS has received a considerable attention recently, however, in case of Vietnam gender aspects of the epidemic have still been a neglected area of research. Little is known about how gender affects the epidemic as well as how the epidemic affects the life of women. This paper reveals that the gender context of HIV/AIDS epidemic in Vietnam has a much complex reality. Institutions, social norms and opportunity structures, of which “Doi Moi” [Renovation] has become an integral part, combine to create new norms and conditions put women more vulnerable to HIV/AIDS. A gendered strategy is crucial in order to successfully fight against the growing HIV/AIDS epidemic

This study reports on the predictive relationship between serological, immunological and pathological responses following experimental inoculation with incremental doses of Fasciola gigantica in sheep. Fifty, 6-month-old, naive Merino wethers were allocated to one of 5 experimental groups, four of which received 50, 125, 225 and 400 metacercariae, respectively, whilst a 5th group acted as non-inoculated control. Strong individual correlations were observed between liver score, GLDH (glutamate dehydrogenase), GGT (gamma glutamyl transferase), CatL5 (cathepsin L5) antibody titre (IgG1, IgA), eosinophilia, and the total worm count or worm biomass. A combination of multiple indicator traits performed significantly better than any single indicator trait alone. The best predictive index accounted for up to 88% of observed worm burden (Wb) if information on inoculation dose was available. Without knowledge of inoculation dose, such as under field conditions, up to 67% of variation in worm burden could be predicted. In contrast, the best single predictor variable (liver damage score) accounted for up to 50% of worm burden, and in the absence of post-slaughter information, serum levels of anti-cathepsin IgA antibody titres accounted for 35% of predicted variation in worm burden. The utility of a predictive index under both field and experimental inoculation conditions is discussed.
Description:
This article reviews research into the genesis and spread of both neighbourhood houses and learning centres in Victoria and community-based men's sheds in Australia to identify some similarities and differences. Our article asks questions about the gendered communities of practice that underpin houses for women on the one hand, and sheds for men on the other. Our particular interest is with the gender issues associated with the development of the relatively mature neighbourhood house 'sector', and those associated with the very recent and developing community-based men's sheds 'sector'. Our underpinning research question has to do with the desirability (or otherwise) in each of these sectors of political and strategic decisions being either gender specific or gender neutral. We identify a number of tantalising parallels between the rationale behind the establishment of both sectors,for women and men, albeit in very different circumstances, along with some obvious differences.

OBJECTIVES: An assessment of linked data was used to investigate the scope and the extent to which hospitalisations data and police crash records represent road crashes in New South Wales (NSW). METHODS: Hospital separation records for the period 1 July 2000 to 30 June 2001, inclusive, were linked to police crash casualty records for the same period using probabilistic record linkage techniques. Multivariable logistic regression techniques were used to identify factors independently associated with the probability of record linkage. RESULTS: Of 17,552 road transport-related hospital records, 45.1% matched to police crash casualty records. When the analysis was restricted to road traffic crashes, 69.2% of the 9,178 records had a matching police crash casualty record. Multivariable analysis found the most significant factors contributing to the likelihood of linkage to be road user type, payment status and principal diagnosis of injury variables. Motor vehicle controllers, cases entitled to financial compensation and cases with a principal diagnosis of injury were significantly more likely to be linked than all other cases. CONCLUSIONS: The findings indicate that researchers and policy makers should be cautious when examining traffic crashes based on a separate analysis of the hospitalisations data and police crash records. This is particularly true for crashes involving pedestrians, cyclists and motorcyclists, and those resulting in less severe injuries. IMPLICATIONS: The findings have implications for use of both police crash records and hospital records in informing the development of strategies designed to prevent road trauma in the community.
Description:
Methods: A six-hour observation of behaviour potentially associated with injury risk was conducted at six public pools and four playgrounds. Supervision and behaviour were quantified using an observational tool based on the Saluja et al.1 model and Morrongiello’s 2 definition of supervision. Infants to 10 year-old children engaged in play and their carers were observed. Child behaviour, corresponding parent supervision, and parental intervention were recorded. Results/Evaluation: Chi-square tests showed higher levels of supervision were associated with specific behaviours in pools and playgrounds. Factors significantly linked to level of parental supervision included child age; parent age; number of children for whom parents were responsible; and in aquatic settings, swimming ability of the child. Discussion: Level of parental supervision differs with children’s play. Despite increased dangers in aquatic environments, parents supervised less at pools than playgrounds highlighting inappropriate parental dependence on lifeguards. Conclusion: Future research examining the relationship between supervision and young children’s risk of drowning at other aquatic environments is required. Attention, proximity and continuity of supervision should be assessed. Findings will enable key water safety stakeholders to further highlight this phenomenon in drowning prevention programs.

This paper focuses on how social movement activists view happiness in relation to their political involvement. Interviewers asked activists questions about their personal histories and feelings. The phenomenological strategy involved focused on interviews with subjects who could speak richly about their commitments and emotions. The data from the 11 subjects revealed that there was no simple relationship between a commitment to social activism and subjects experiences of happiness. Several subjects oriented their responses to the relationship between meaningfulness, activism, and happiness. In discussion of the analyzed data, the authors suggest that a relationship is evident between the positions articulated by interviewees and their levels of engagement in and withdrawal from activism.
