Australia's strengths and weaknesses in technology transfer and R&D exploitation : GEM survey "experts" views compared with public policy and other published data

There has been increasing public debate in Australia in recent years about research culture in universities and other publicly funded research agencies such as CSIRO and its impact on Australia's performance in generating economic, social and environmental benefits to the Australian community from the large amount of public funding for R&D. This is the supply side issue. On the demand side there is equally concern about the technology absorptive capacity of Australian. business as illustrated by the low proportion of gross business research expenditure (GERD) spent by business (BERD). Against this background, this paper has explored the views of abut 100 "experts" interviewed in the Australian Global Entrepreneurship Monitor (GEM) studies in the years 2000, 2001, 2002 and 2003 on the issues, strengths and weaknesses of Australia's technology transfer performance as it applies to new technology small firms. The paper has also explored evidence for any longitudinal change over this period.

Nutrient contribution to hyper-eutrophic wetlands in Perth, Western Australia

This thesis investigates nutrient contribution to six hyper-eutrophic lakes located within close proximity of each other on the Swan Coastal Plain and 20 kilometres south of the Perth Central Business District, Western Australia. The lakes are located within a mixed land use setting and are under the management of a number of state and local government departments and organisations. These are a number of other lakes on the Swan Coastal Plain for which the majority are less than 3 metres in depth and considered as an expression of the groundwater as their base is below the regional groundwater table throughout most of the year. The limited amount of water quality data available for these six lakes and the surface water and groundwater flowing into them has restricted a thorough understanding of the processes influencing the water quality of the lakes. Various private and public companies and organisations have undertaken studies on some of the individual wetlands and there is a wide difference in scientific opinion as to the major source of the nutrients to those wetlands. These previous studies failed to consider regional surface water and groundwater effects on the nutrient fluxes and they predominantly only investigated single wetland systems. This study attempts for the first time to investigate the regional contribution of nutrients to this system of wetlands existing on the Swan Coastal plain. As such, it also includes new research on the nutrient contribution to some of the remaining wetlands. The research findings indicate that the lake sediments represent a considerable store of nutrients (nitrogen and phosphorus). These sediments in turn control the nutrient status of the lake's water column. Surface water is found to contribute on an event-basis load of nutrients to the lakes whilst the groundwater surprisingly appears to contribute a comparatively low input of nutrients but governs the water depth. Analysis of the regional groundwater shows efficient denitrifying abilities as a result of denitrifying bacteria and the transport is localised. Management recommendations for the remediation of the social and environmental value of the lakes include treatment of the lake’s sediments via chemical bonding or atmospheric oxidation; utilising the regional groundwater’s denitrifying abilities to ‘treat’ the surface water via infiltration basins; and investigating the merits of managed or artificial aquifer recharge (MAR).

Public and stakeholder values and knowledge of wildlife in Victoria, Australia

Prompted by a lack of human dimensions research in Australia, this study investigated the values and knowledge relating to wildlife held by members of the public within distinct demographic subsets of the Victorian population and members of wildlife management stakeholder groups; and compared these characteristics with how Victorian wildlife managers perceive these groups. A combination of semi-structured interviews and postal questionnaires were used. Fifteen in-depth interviews were conducted to explore how wildlife managers perceive the values and knowledge of wildlife held by members of various subsets of the Victorian population. A total of 1,431 questionnaires were completed by members of 13 public and stakeholder groups throughout Victoria, and these were analysed to explore values and knowledge relating to wildlife in Victoria. The findings of this study suggest that Victorian people have a strong emotional attachment to individual animals (the humanistic value), and an interest in learning about wildlife (the curiosity/learning/interacting value). The dominionistic/wildlife-consumption, utilitarian-habitat, aesthetic and negativistic values were not expressed by the majority of respondents from the public samples. The data also suggest that Victorian people have relatively low levels of factual knowledge about Australian wildlife. Thus, wildlife managers should expect support for wildlife management objectives that reflect the strong humanistic orientation of Victorians and tailor management and education programs to appeal to this value and Victorians' interest in learning about wildlife. Members of the Field Naturalists Club of Victoria (FNCV), Bird Observers Club of Australia (BOCA), Australian Conservation Foundation (ACF) stakeholder groups and management agency Parks Victoria expressed a strong interest in learning about wildlife. Members of the Royal Society for the Prevention of Cruelty to Animals (RSPCA) obtained high humanistic value scores; and members of the Victorian Field and Game Association (VFGA) obtained high domimomstic/wildlife-consumption value scores. Importantly, the humanistic and curiosity/learning/interacting values were the most strongly expressed values in all six groups and these values could be the key to more effective communication and collaboration between groups. Relationships between demographic factors, and values and knowledge relating to wildlife were found. For example, rural Victorians held a stronger dominionistic/ wildlife-consumption value than urban Victorians; females held stronger humanistic, curiosity/learning/interacting and negativistic values than males; young Victorians (18-34 years) held a lower curiosity/learning/interacting value and lower factual knowledge of wildlife than older Victorians; and more highly educated Victorians were more knowledgeable about wildlife than people with less formal education. No statistically significant differences were found between the values and knowledge of wildlife held by different income classes. While relationships between demographic factors, and values and knowledge relating to wildlife were found, they were generally much smaller than expected based on wildlife managers' perceptions and previous research. For example, the results suggest that Victorian females have a slightly stronger humanistic value of wildlife than males do. However, the important message emerging from the data is that males and females both express a strong emotional attachment to individual animals. Importantly, the results indicate that the effects of demographic factors on values and knowledge relating to wildlife are not always consistent across different geographic locations and stakeholder groups. For example, the slightly stronger interest in learning about wildlife among females when compared with males was observed in the rural and urban-fringe samples but not in the urban samples. This suggests that caution must be used when generalising the findings from human dimensions studies from one type of community or stakeholder group to another. Management programs should be tailored to the specific characteristics of the target audience. The findings also indicate that Victorian wildlife managers have diverse perceptions about the values and knowledge of wildlife held by members of different publics and stakeholder groups, and that the perceptions held by wildlife managers are not always consistent with the actual values and knowledge of wildlife held by members of different publics and stakeholders. For example, counter to the perceptions expressed by the interviewed wildlife managers, the interest in and factual knowledge of wildlife held by members of voluntary conservation groups equalled or surpassed that of wildlife managers; young Victorian adults (18-34 years) held a slightly lower curiosity/learning/interacting value and slightly lower level of factual knowledge of wildlife than older Victorians; and rural and urban communities in Victoria held low dominionistic and utilitarian values. Such discrepancies highlight the importance of investigating the actual values and knowledge held by members of such groups, so that appropriate and effective wildlife management programs can be implemented. Inaccurate perceptions and assumptions may contribute to ineffective communication between managers, stakeholders and publics; and adversely effect the success of wildlife management programs.

Determinants of efficient risk allocation in privately financed public infrastructure projects in Australia

Risk allocation in privately financed public infrastructure projects, which are mainly referred to as public-private partnership (PPP) projects, is a challenging job due to the nature of incomplete contracting. An investigation into the mechanism that guides the formation of efficient risk allocation strategies is thus desirable. Drawing on the transaction cost economics and resource-based view of organizational capability, this paper has identified five main features of the transactions associated with risk allocation in PPP projects. They include partners’ risk management routine, partners’ risk management mechanism, partners’ cooperation history, risk management environmental uncertainty, and partners’ risk management commitment. For achieving cost efficiency, different risk allocation strategies may suit different conditions of the features. Accordingly, a theoretical framework and five hypotheses were proposed for testing. Data collected in an industrywide survey were analyzed using multiple linear regression technique. It was found that generally, the identified features are determinants in the decision-making process of efficient risk allocation. Therefore, the proposed theoretical framework provides both government and private agencies with not only a logical and holistic understanding of but also a support tool for decision making on risk allocation strategy in PPP projects. Study limitations and future research directions are also set out.

Modelling the public health consequences of cannabis use in Australia

Aims: To detail and validate a simulation model that describes the dynamics of cannabis use, including its probable causal relationships with schizophrenia, road traffic accidents (RTA) and heroin/poly-drug use (HPU).

Methods: A Markov model with 17 health-states was constructed. Annual cycles were used to simulate the initiation of cannabis use, progression in use, reduction and complete remission. The probabilities of transition between health-states were derived from observational data. Following 10-year-old Australian children for 90 years, the model estimated age-specific prevalence for cannabis use. By applying the relative risks according to the extent of cannabis use, the age-specific prevalence of schizophrenia and HPU, and the annual RTA incidence and fatality rate were also estimated. Predictive validity of the model was tested by comparing modelled outputs with data from other credible sources. Sensitivity and scenario analyses were conducted to evaluate technical validity and face validity.

Results: The estimated cannabis use prevalence in individuals aged 10-65 years was 12.2% which comprised 27.4% weekly and 18.0% daily users. The modelled prevalence and age profile were comparable to the reported cross-sectional data. The model also provided good approximations to the prevalence of schizophrenia (Modelled: 4.75/1,000 persons vs Observed: 4.6/1,000 persons), HPU (3.2/1,000 vs 3.1/1,000) and the RTA fatality rate (8.1 per 100,000 vs 8.2 per 100,000). Sensitivity analyses and scenario analysis provided expected and explainable trends.

Conclusions: The validated model provides a valuable tool to assess the likely effectiveness and cost-effectiveness of interventions designed to affect patterns of cannabis use. It can be updated as new data becomes available and/or applied to other countries.

Raising the profile of public health ethics in Australia : time for debate

This paper argues for greater dialogue on public health ethics. There has been little discussion in Australia about the significant ethical dilemmas in this field, and there is no agreed framework for analysing and responding to these challenges. We highlight concerns about the suitability of biomedical principles-based ethics for public health, and encourage public health professionals in this country to reflect on ethical challenges in public health research. A focus on research ethics concerns will deliver concrete examples demonstrating the need for a public health ethics frame work. Recommendations are offered for how public health ethics promotion may occur locally.
