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.

Text in German / This dissertation describes and interprets the history of Presbyterian Youth Ministry from the beginning up to today. The Presbyterian Church of Ghana originated from the work of the Basel Mission, Switzerland and the United Free Church of Scotland. The emphasis on education, laid by the Basel Mission has had a major impact for the Church and especially for Youth Ministry. This emphasis was seen through the building of Schools, Training Institutions and through practical training of young people. Andrew Atkinson, a Scottish accountant at the then Gold Coast, laid the foundation for youth work within the Church. Very soon this ministry developed throughout the country. With the formation of a Youth Constitution as the basis for youth work, a good framework was established that still guides the Youth today. Today, Youth work has been broadened. Through different projects it is envisaged to give answers to the manifold problems of young people in a fast changing African society. Social projects, HIV/AIDS work, but at first the training of young people is a major part of youth work today. Conferences are held on different levels, training materials have been developed and youth workers have been trained to take up future responsibilities as leaders. One emphasis has remained and has its roots in the Basel Mission history: a Bible based youth ministry that equips young people to follow Christ as disciples in their day-to-day lives. Within this success story there has of course also been some failure and weakness. Both, success and struggle is evident within this dissertation. / Missiology / M. Th (Missiology)

Text in German / This doctoral thesis deals with the changes the youth grapple with in Southern Ghana today. These changes permeate all fabrics of society, from the traditional society with its values to the modern society that is undergoing radical social changes. The First Part presents to the reader the traditional Akan Society. It points out how it has assisted young people to get into the world of the adult. It gives an insight into the traditional religions, the rites and practices associated with them and their relation to young people. The Second Part deals with the History of the Presbyterian Youth Work from its inception to the present day. The Presbyterian Church of Ghana was set up in the early 20th Century from the toils of the Basel Mission and the United Free Church of Scotland. This new Christian way of life brought a clash between two world views: the traditional African Religion (ATR) and the Christian Religion that brought about, so to say, farreaching consequences to the culture and the development of the country. Part three focuses attention on the present changes in the Ghanaian Society. It shows the effects of migration and the economic conditions on the Ghanaian Society at the turn of the 21st Century especially for young people. Part four sums up the findings and discusses them on the basis of two leading concepts: Contextualization and Identity. I evaluated a contextualization project of a church parish in southern Ghana. Here are, in my opinion, the first signs that could show the way into the future, i.e. a way of preaching the Gospel within the context of the traditional mindset of the local people by taking into account the Ghanaian Culture and with due regard to the feelings of the youth. / Christian Spirituality, Church History and Missiology / D.

Although the physical characteristics of surfing breaks are well described in the literature, there is little specific research on surfing and coastal management. Such research is required because coastal engineering has had significant impacts to surfing breaks, both positive and negative. Strategic planning and environmental impact assessment methods, a central tenet of integrated coastal zone management (ICZM), are recommended by this thesis to maximise surfing amenities. The research reported here identifies key oceanographic considerations required for ICZM around surfing breaks including: surfing wave parameters; surfing break components; relationship between surfer skill, surfing manoeuvre type and wave parameters; wind effects on waves; currents; geomorphic surfing break categorisation; beach-state and morphology; and offshore wave transformations. Key coastal activities that can have impacts to surfing breaks are identified. Environmental data types to consider during coastal studies around surfing breaks are presented and geographic information systems (GIS) are used to manage and interpret such information. To monitor surfing breaks, a shallow water multibeam echo sounding system was utilised and a RTK GPS water level correction and hydrographic GIS methodology developed. Including surfing in coastal management requires coastal engineering solutions that incorporate surfing. As an example, the efficacy of the artificial surfing reef (ASR) at Mount Maunganui, New Zealand, was evaluated. GIS, multibeam echo soundings, oceanographic measurements, photography, and wave modelling were all applied to monitor sea floor morphology around the reef. Results showed that the beach-state has more cellular circulation since the reef was installed, and a groin effect on the offshore bar was caused by the structure within the monitoring period, trapping sediment updrift and eroding sediment downdrift. No identifiable shoreline salient was observed. Landward of the reef, a scour hole ~3 times the surface area of the reef has formed. The current literature on ASRs has primarily focused on reef shape and its role in creating surfing waves. However, this study suggests that impacts to the offshore bar, beach-state, scour hole and surf zone hydrodynamics should all be included in future surfing reef designs. More real world reef studies, including ongoing monitoring of existing surfing reefs are required to validate theoretical concepts in the published literature.
