The nature of errors made by drivers [Austroads Publication no: AP-R378-11]

It is important that we understand the factors and conditions that shape driver behaviour – those conditions within the road transport system that contribute to driver error and the situations where driver non-compliance to road regulations is likely. This report presents the findings derived from a program of research investigating the nature of errors made by drivers, involving a literature review and an on-road study. The review indicates that, despite significant investigation, the role of different error types in road traffic crashes remains unclear, as does the role of the wider road transport system failures in driver error causation.

Profiling the nature and context of the Australian prefabricated housing industry

The current state of the prefabricated housing market in Australia is systematically profiled, guided by a theoretical systems model. Particular focus is given to two original data collections. The first identifies manufacturers and builders using prefabrication innovations, and the second compares the context for prefabricated housing in Australia with that of key international jurisdictions. The results indicate a small but growing market for prefabricated housing in Australia, often building upon expertise developed through non-residential building applications. The international comparison highlighted the complexity of the interactions between macro policy decisions and historical influences and the uptake of prefabricated housing. The data suggest factors such as the small scale of the Australian market, and a lack of investment in research, development and training have not encouraged prefabrication. A lack of clear regulatory policy surrounding prefabricated housing is common both in Australia and internationally, with local effects in regards to home warranties and housing finance highlighted. Future research should target the continuing lack of consideration of prefabrication from within the housing construction industry, and build upon the research reported in this paper to further quantify the potential end user market and the continuing development of the industry.

Attributing human uniqueness and human nature to cultural groups : distinct forms of subtle dehumanization

Research on subtle dehumanization has focused on the attribution of human uniqueness to groups (infrahumanization), but has not examined another sense of humanness, human nature. Additionally, research has not extended far beyond Western cultures to examine the universality of these forms of dehumanization. Hence, the attribution of both forms of humanness was examined in three cross-cultural studies. Anglo-Australian and ethnic Chinese attributed values and traits (Study 1, N = 200) and emotions (Study 2, N = 151) to Australian and Chinese groups, and rated these characteristics on human uniqueness and human nature. Both studies found evidence of complementary attributions of humanness for Australians, who denied Chinese human nature but attributed them with greater human uniqueness. Chinese denied Australians human uniqueness, but their attributions of human nature varied for traits, values, and emotions. Study 3 (N = 54) demonstrated similar forms of dehumanization using an implicit method. These results and their implications for dehumanization and prejudice suggest the need to broaden investigation and theory to encompass both forms of humanness, and examine the attribution of both lesser and greater humanness to outgroups.

Conceptual beliefs about human values and their implications: Human nature beliefs predict value importance, value trade-offs, and responses to value-laden rhetoric

Beliefs that may underlie the importance of human values were investigated in 4 studies, drawing on research that distinguishes natural-kind (natural), nominal-kind (conventional), and artifact (functional) beliefs. Values were best characterized by artifact and nominal-kind beliefs, as well as a natural-kind belief specific to the social domain, “human nature” (Studies 1 and 2). The extent to which values were considered central to human nature was associated with value importance in both Australia and Japan (Study 2), and experimentally manipulating human nature beliefs influenced value importance (Study 3). Beyond their association with importance, human nature beliefs predicted participants’ reactions to value trade-offs (Study 1) and to value-laden rhetorical statements (Study 4). Human nature beliefs therefore play a central role in the psychology of values.

The fluid nature of action research

Action research is a fluid, unfolding process of research. It involves cycles of questioning, gathering data, critical reflection and deciding on a course of action (Stringer, 2008). Through action research, educators research their own practice in their own setting. They learn from their experiences as the action research cycles progress, and apply new learning to practice.

Adaptive nature of coordinated road traffic injury prevention responses in some OECD countries

This study examines the context of coordinated responses, triggers for coordinated responses, and preference for or choice of coordinating strategies in road traffic injury prevention at a local level in some OECD countries. This aim is achieved through a mixed-methodology. In this respect, 22 semi-structured interviews were conducted with road traffic injury prevention experts from five OECD countries. In addition, 31 professional road traffic injury prevention stakeholders from seven OECD nations completed a self-administered, online survey. It found that there was resource limitation and inter-dependence across actors within the context of road traffic injury prevention at a local level. Furthermore, this study unveiled the realization of resource-dependency as a trigger for coordinated responses at a local level. Moreover, the present examination has revealed two coordinating strategies favored by experts in road traffic injury prevention – i.e. self-organizing community groups, which are deemed to have a platform to deliver programs within communities, and the funding of community groups to forge partnerships. However, the present study did not appear to endorse other strategies such as the formalization of coordinated responses or a legal mandate to coordinate responses. In essence, this study appears to suggest a need to manage coordinated responses from an adaptive perspective with interactions across road traffic injury prevention programs being forged on a mutual understanding of inter-dependency arising out of resource scarcity. In fact, the role of legislation and top-down national models in local level management of coordinated responses is likely to be one of identifying opportunities to interact with self-organized community groups and fund partnership-based road traffic injury prevention events.

The dual nature of information systems in enabling a new wave of hardware ventures: Towards a theory

Hardware ventures are emerging entrepreneurial firms that create new market offerings based on development of digital devices. These ventures are important elements in the global economy but have not yet received much attention in the literature. Our interest in examining hardware ventures is specifically in the role that information system (IS) resources play in enabling them. We ask how the role of IS resources for hardware ventures can be conceptualized and develop a framework for assessment. Our framework builds on the distinction of operand and operant resources and distinguishes between two key lifecycle stages of hardware ventures: start-up and growth. We show how this framework can be used to discuss the role, nature, and use of IS for hardware ventures and outline empirical research strategies that flow from it. Our work contributes to broadening and enriching the IS field by drawing attention to its role in significant and novel phenomena.

Re-thinking sustainable solutions: Innovation inspired by nature

Australian rural landscapes are facing a crisis from land degradation due to rising salinity levels, soil acidification and soil erosion. There is growing consensus amongst the businesses community, government departments and research organisations that the real solution to these problems and the broader sustainability dilemma comes by taking a ‘whole of system’ approach to agricultural and rangelands management. This article introduces two cutting-edge concepts – Biomimicry and Natural Sequence Farming – to illustrate how whole-system thinking can effectively and profitably address the challenges facing agriculture and rangelands.

The nature of academic leadership at the colleges of the Royal University of Bhutan

This qualitative case study explored leaders' and faculty members' perspectives on the nature of academic leadership at the Royal University of Bhutan (RUB) Colleges. The study revealed that academic leadership at the Colleges is a complex and emergent fusion of Western and Buddhist leadership. The research recommended a hybrid model intended to inform academic leadership development in Bhutanese higher education and contribute to the realisation of the Gross National Happiness philosophy. The model incorporates Buddhist-influenced leadership and other relevant leadership approaches and is expected to contribute to academic rigour through effective learning and research leadership.

Mandatory reporting laws: Their origin, nature, and development over time

Dozens of countries have enacted mandatory reporting laws in various forms to respond to child abuse and neglect. Other countries including England are currently considering whether to introduce them, and if so in what form. It is important for policymakers, practitioners and researchers to understand these laws’ background, nature and purpose. This chapter outlines the origins and provenance of the first mandatory reporting laws; discusses their nature; describes major developments over time; and identifies some major effects and their consequences. It is shown that the laws are a heterogeneous, organic, flexible mechanism enabling social intervention where otherwise such intervention is severely compromised or impossible. Their primary function is to comprise but one aspect of a multifaceted child welfare system by identifying cases of serious maltreatment which would not otherwise come to light: sexual abuse and severe physical abuse are paradigm examples. The essential role of these laws is therefore primarily a tertiary aspect of a public health model, rather than a purely preventative strategy. Mandatory reporting laws are made by each specific jurisdiction according to its preferred design and function within its socio-political system. There is a spectrum of different approaches from which a jurisdiction can choose: they can apply to a broad or a narrow range of reporter groups, a broad or a narrow range of types of maltreatment, and a broad or a narrow range of instances where abuse or neglect occurs.

Atmospheres : Aesthetics of emotional spaces[Review]

More problematic than his avoidance of recent geographic scholarship is his treatment of indigenous, ethnographic and postcolonial perspectives on island life. Not only is much of this scholarship absent, the bits that are there are mostly derided. He slams Kamau Braithwaite and his concept of ‘tidalectics’ as ‘unpackable’ (p. 20) and also claims that Greg Dening’s approach to islands as having ‘permeable cultural boundaries’ has ‘intellectual costs’ (p. 23). In a section of the book on ‘Naming and Sovereignty’, instead of an in-depth examination of the processes of decoding and recoding that goes on in indigenous island landscapes under colonialism (as could be discussed at length if Shell chose to examine Aotearoa, Hawaii, or hundreds of other places) we are instead presented a vignette about his childhood street fights with other kids over the naming of a hometown island in Canada, as well as ruminations about what Herman Melville and Ellen Semple thought of islands in the nineteenth century. In short, if you want to know what dead Caucasians like Shakespeare, Melville, Kant, Mackinder, More, and ancient Athenians thought about islands, then this book is a good resource. If, however, you are looking for information about what islands are like today – and what they mean to the people who live on and interact with them – then you will have to look elsewhere.

Nature and extent of genetic diversity of dengue viruses determined by 454 pyrosequencing

Dengue virus (DENV) populations are characteristically highly diverse. Regular lineage extinction and replacement is an important dynamic DENV feature, and most DENV lineage turnover events are associated with increased incidence of disease. The role of genetic diversity in DENV lineage extinctions is not understood. We investigated the nature and extent of genetic diversity in the envelope (E) gene of DENV serotype 1 representing different lineages histories. A region of the DENV genome spanning the E gene was amplified and sequenced by Roche/454 pyrosequencing. The pyrosequencing results identified distinct sub-populations (haplotypes) for each DENV-1 E gene. A phylogenetic tree was constructed with the consensus DENV-1 E gene nucleotide sequences, and the sequences of each constructed haplotype showed that the haplotypes segregated with the Sanger consensus sequence of the population from which they were drawn. Haplotypes determined through pyrosequencing identified a recombinant DENV genome that could not be identified through Sanger sequencing. Nucleotide level sequence diversities of DENV-1 populations determined from SNP analysis were very low, estimated from 0.009-0.01. There were also no stop codon, frameshift or non-frameshift mutations observed in the E genes of any lineage. No significant correlations between the accumulation of deleterious mutations or increasing genetic diversity and lineage extinction were observed (p>0.5). Although our hypothesis that accumulation of deleterious mutations over time led to the extinction and replacement of DENV lineages was ultimately not supported by the data, our data does highlight the significant technical issues that must be resolved in the way in which population diversity is measured for DENV and other viruses. The results provide an insight into the within-population genetic structure and diversity of DENV-1 populations.

The nature of malnutrition in children with end-stage liver disease awaiting orthotopic liver transplantation

To evaluate malnutrition in chronic liver disease, and its relationship to nutrient deficiencies and hepatic dysfunction. 27 children with end-stage liver disease were studied. Mean protein-energy intakes were 70% of recommended daily intakes. The patients were underweight and stunted with reduced mean triceps and subscapular skinfold thicknesses and midupper arm circumference. Mean total body potassium was only 63 ± 18% of that expected for age and sex. Deficiency of essential fatty acids (32%), and low concentrations of fat-soluble vitamins (A, 92%; E, 32%), iron (32%), zinc (42%), and selenium (13%) were common. Serum ammonia concentrations were raised in all patients, and increased methionine, tyrosine, and glutamic acid, and reduced glutamine concentrations were noted. There was no correlation between the degree of malnutrition and the degree of liver synthetic function, the degree of cholestasis, or the degree of liver injury. We suggest that potentially correctable factors in addition to liver failure (eg, inadequate absorbed intake) were important determinants of malnutrition in these patients.
