Culicoides molestus (Skuse) is the major species of biting midge that plagues human comfort in the estuarine Gold Coast region of southeast Queensland. Local authorities have initiated a search for an effective, non-chemical means of control, that would minimize human-midge interaction. The effectiveness of a program to control an organism, such as a biting midge, is dependent upon knowledge of the biology of the particular organism of interest. This project revolved examines the lifecycle of C. molestus in detail. It addresses questions regarding the location, seasonal distribution, and dispersal of its juvenile stages in the sand of infested beaches, and their response to chemical treatment, the monthly and annual cycles of the adult midge, and the possibilities of achieving laboratory oviposition, as a first step to laboratory colonisation. The distribution of eggs, larvae and pupae of C. molestus was found to be mostly concentrated around, but below, mean tide level. They also occurred well below the mean tide level. Eggs and larvae have been recovered from as deep as 10 cm in the sand. A seasonal study of the juveniles of this species indicated that they were more strongly influenced by tides than seasons. After a routine pest-control larviciding treatment, a beach recolonisation study revealed that beaches become suitable for oviposition approximately two months after treatment. Large larvae invaded the sprayed areas within days of treatment, which suggests the existence of a refuge outside of the reach of the insecticide. Larvae found in clean (egg- and larva-free), isolated sand containers, placed on the study beach, indicated that larvae could swim in or on the water as a way of moving around the beach. Extended bite-rate studies highlighted the existence of four peaks in adult midge biting activity during the course of a year, around the mid seasons. The strongest peaks of activity were found to be in autumn and spring, but the data suggest that the species undergoes four generations in a year. Through a series of trial-and-error experiments, oviposition under laboratory conditions was achieved. Although the time from blood-feeding to egg maturation is not yet well determined, it occurs within an eight day mean survival period. Blood quality appears critical for adult blood-fed midge survival. Midges fed on the blood of a volunteer who was frequently exposed to midge bites do not live long enough to mature its eggs. The partial ovarial development of one unfed adult female, reared in the laboratory, indicates that C. molestus is facultatively anautogenous.

The study investigated the self-reported information needs and information-seeking behaviour of 143 general practitioners in their delivery of patient care to the elderly on the Gold Coast. The study sought to obtain an information profile in order to begin discussion on the need for possible infrastructures that may need to be considered in any planning strategies concerned with access to and provision of relevant, accurate and timely information to general practitioners which affects their delivery of patient care to the growing number of elderly patients. A ten-page questionnaire utilising both structured and unstructured questions was returned by 61.9 percent of the survey population. Demographic characteristics indicated that respondents were representative of general practitioners in Australia. Respondents frequently needed information with 40 percent requiring it '1 - 4 times a week' and 78 percent 'once a month or more often'. Information on medical fact was required most frequently, 29 percent, medical opinion 27 percent, and non-medical information 23 percent. The study found support for the proposition that computerised information systems need to be enhanced and made widely known and available to general practitioners to assist them in obtaining information that they need in delivery of patient care to the elderly. There is a great need by these general practitioners for non-medical information as well as medical information. Therefore, the development of a database of non-medical information containing information on local agencies and services is of high priority. Library information delivery services should also be de-institutionalised in terms of lifting restrictions to services provided to enable general practitioners greater access to information. Library services should aim to provide remote access to information via telephone, fax and modem with emphasis on value added services aimed at solving a particular specific information need as well as straight-out bibliographic search services and document delivery services. Continuing medical education in the form of CME courses, conferences and meetings should focus on specific information needs of general practitioners in this area of patient care to the elderly. The need for information on cardiology, orthopaedics, dermatology, physiotherapy, podiatry, pharmaceutical benefits, home help, Meals-on-Wheels and nursing home placement were areas of particular interest identified by respondents in this study.

Tourism has come to be recognised as a major contributor to national economies. In a knowledge-based economy (that emphasises the benefits of industry/government and academic research), a strong research base must underpin management of a tourist destination if it is to realise its full potential. The establishment of collaborative networks between industry, academia, and government in the strategic planning and management of cities and towns is becoming increasingly popular. However, the way in which the processes underlying these settings facilitate or inhibit eventual outcomes is poorly understood. If knowledge is to drive innovation and economic growth optimally, it is important not just to develop an understanding of the processes underlying the creation, diffusion and utilisation of knowledge in cooperative research settings, but also the relationships among them. Accordingly, the aim of this investigation is to examine the relationships among knowledge creation, diffusion and utilisation occurring in the Cooperative Research Centres (CRC) Program, specifically, the Gold Coast Visioning Project, with a view to identifying the most efficient means for formulating and disseminating research designed for industry and/or government application. Knowledge is defined as information that is imbued with meaning or relevance. However, this definition says little of the ways that individuals, groups and organisations acquire knowledge. While cognitive psychologists have produced several theories suggesting the structure and mechanisms of individual cognitive processes underlying the acquisition and use of knowledge, social scientists have sought to describe and explain the process by investigating the influence of social factors. Recent contributions to group learning have examined group composition, group size, familiarity among group members, and communication processes in an attempt to understand the ways in which groups acquire knowledge. Research shows that knowledge utilisation in organisations results from the interdependent influences of organisational processes and the control opportunities and control problems that arise through organisational structure. These frameworks provide accounts of how knowledge is utilised within an organisation, but not of how organisations learn. Recent research suggests that organisations learn through knowledge networks where organisational focus moves from the consideration and protection of boundaries to the management of (and care for) relationships. Therefore, organisations contain static (rules, norms and procedures) and dynamic (social relationships) elements that mutually influence the degree to which organisations learn. A synthesis of the available literature resulted in the development of a series of models that served not only to inform, but also be informed by the analysis of this investigation. A single case study, namely the Gold Coast Visioning Project, was used to examine the ways in which knowledge was created, disseminated and utilised in a CRC setting. This ethnographic investigation considered the process of knowledge creation through to utilisation at individual, group, organisational, and inter-organisational levels, while simultaneously examining the interrelated influences of social, cognitive, affective and communication factors. Throughout the project, data were collected through stakeholder interviews, various documents and participant observation of stakeholder meetings and workshops. Data were analysed using a grounded theory approach and methods of thick description. The results show that researchers and industry stakeholders bring different frames of reference, different expectations, and different knowledge bases to the exercise. This inhibited communication, and gave the appearance of dissension when, in fact, what was being sought was a common frame for understanding and communication. Additionally, the gap between industry and researcher worldviews generated the sense that industry was resisting or failing to understand what the research was seeking to achieve. Consequently, in order to manage the relationship, research plans and findings were communicated to industry in a teacher-to-student fashion, which fostered single-loop learning, and reduced industry stakeholders' sense of ownership in the process and findings. During the project, industry stakeholders frequently sought to have research come pre-packaged with "meaning", but researchers lacked the contextual knowledge necessary to specify the relevance of their research. The results also show that research findings need to be integrated and diffused to industry over time, and specific applications need to be formulated (and reformulated) in response to particular and changing needs of industry. As a result of this investigation, a model of 'best practice' has been developed with detailed recommendations for the design, implementation, and reporting of CRC-sponsored research to optimise its utility for end-users of such research. From a theoretical perspective, the findings of this study challenge the ways that current theories account for the ways in which knowledge is acquired and utilised since the results show that knowledge is constructed both socially and emotionally. Any investigation that seeks to understand how knowledge is acquired and utilised must consider social and affective influences. To ignore the role of emotion and values in the process of knowledge acquisition is to ignore a key component of an individual's reasoning capacity.

The main objective of this study was to examine the abundance and diversity of ants in suburban sites following vegetation removal or modification for development. This research examines the capacity of suburban sites to support ant diversity, which is dependent on the site characteristics and their surrounding environment. The study focused on 29 suburban garden and 3 suburban reserve sites on the Gold Coast, Queensland, Australia. This region, through continuing land development, undergoes ongoing habitat disturbance and modification. Ground-dwelling ants were collected by pitfall trapping in study sites over three summers between 1997 and 1999. In total, 28,512 ants from 60 species in 31 genera were collected. Garden sites that maintain vegetation structural diversity were found to be most similar to reserve sites in terms of ant community composition. These sites were highest in ant richness and diversity and contained particularly high proportions of specialized ant species. Sites in close proximity to remnants of native vegetation contained higher species diversity and a greater proportion of specialized ant species. The introduced tramp ant, Pheidole megacephala was found in 28 of the 32 sites and was found to significantly reduce ant species richness and diversity and displace the dominant ant Iridomyrmex sp. 1 in suburban environments. This ant poses a serious threat to the recovery of a diverse ant fauna to suburban environments. Ant community composition was shown to vary significantly among suburban sites. The ant functional groups commonly found in disturbed sites were abundant in open sites with little canopy cover in this study. Sites that provided vegetation structural diversity and areas of closed canopy supported similar functional groups to natural vegetation remnants. These results indicate that ant communities in suburban environments respond to disturbance in a similar manner to ant communities in tropical forests and rainforests. The dominance by functional groups and presence of specialized species may therefore be used as an indicator of disturbance and the restoration of suitable habitat in suburban sites. The presence of specialized species of ants in suburban garden sites and their clear preference for particular site characteristics indicate that these species utilize resources available in the suburban matrix. These results indicate that residential suburban sites are of value in the enhancement of ant diversity in fragmented landscapes and that they may provide supportive habitat to, and act as corridors between, vegetation fragments. In order to preserve biodiversity within suburban environments, landowners should be advised to retain as much existing vegetation within a site as possible. Clearing should be limited to that necessary to allow construction of dwellings and for safety. In addition, landowners should be encouraged to establish or maintain structurally diverse vegetation layers within sites in order to provide diverse microenvironments for fauna habitat.
