<p> The Gal&aacute;pagos Archipelago is recognized internationally as a unique eco-region, and many of the species that inhabit these islands can be found nowhere else on Earth. The Ecuadorian government recognized the value of this ecosystem, and, beginning in 1959, they designated 97% of the Archipelago as Ecuador's first National Park. The Charles Darwin Foundation also was founded in 1959 and, since then, the Park Service and the Foundation have worked towards preserving the Gal&aacute;pagos' unique flora and fauna for future generations. The waved albatross (<i>Phoebastria irrorata</i>) is the largest bird species found in the Gal&aacute;pagos Archipelago and was recognized as an iconic species early in the Park's history; it is the only tropical albatross. This species spends the majority of its life foraging at sea and is an important predator in the Humboldt Current off of the coast of South America. With the exception of a few pairs, this albatross breeds entirely on the southeastern most island of the archipelago, Espa&ntilde;ola. Tourists visit Espa&ntilde;ola every year to watch the elaborate courtship dances of this species, and albatrosses in general have been the foci of legends among sailors for centuries. </p><p> M.P. Harris (1969) began banding waved albatross as early as 1961, marking the beginning of a long-term monitoring program with a focus on estimating age-specific first-time breeding, abundance, and survival. This initial effort resulted in the first estimates of abundance and survival for the waved albatross (Harris 1973). Following these initial estimates, the population size of the waved albatross has been estimated in 1994 (Douglas 1998), 2001 (Anderson et al. 2002), and 2007 (Anderson et al. 2008). These estimates suggest that the population has been declining since 1994. Motivated by this apparent decline, Awkerman et al. (2006) investigated survival and concluded that survival estimates from 1999-2005 were lower than average survival from 1961-1970 (Harris 1973). Today, the waved albatross is considered critically endangered, with bycatch in artisanal longline fisheries and the increased occurrence of El Ni&ntilde;o-Southern Oscillation events thought to be contributing to these observed declines in survival and abundance. Given these observed declines in the waved albatross, the importance of the species in the ecosystem, and its intrinsic value in terms of biodiversity, continued monitoring and analysis efforts are needed to evaluate trends over time, and to gauge the effectiveness of management actions. My thesis is focused on these topics. </p><p> In Chapter 1:, I describe a framework to estimate abundance of wildlife populations, apply this framework to estimate population size of the waved albatross at a major breeding colony on Espa&ntilde;ola Island, and I conclude by providing recommendations for future island-wide surveys of this species. </p><p> In Chapter 2:, I revisit the dataset collected by M.P. Harris and the Gal&aacute;pagos National Park from 1961-1981 as well as a more recent dataset collected by K.P. Huyvaert and colleagues. I analyzed these datasets in a multistate mark-recapture framework to estimate and compare estimates of adult survival as well as other important demographic parameters that have not yet been evaluated for this species. </p><p> Bycatch from fisheries and extreme weather events have influenced survival and breeding probabilities of many pelagic seabird species worldwide. Lower adult survival of the waved albatross is thought to be associated with bycatch in the small-scale fishery located off of the coasts of Peru and Ecuador as well as with El Ni&ntilde;o-Southern Oscillation events. Previous efforts to document these threats have not formally considered that a variable proportion of the population does not breed every year or that different life history stages may have different survival rates. </p><p> The results from Chapter 1 suggest a continued decline in the principal breeding population of the waved albatross since 1994, and Chapter 2 shows indirect evidence that this decline may be linked to higher mortality associated with recent documented increases in small-scale longline fishing effort off of the coast of South America. Outside of the Galapagos Marine Reserve where fishing is heavily regulated by the Galapagos National Park Service, little is done to directly manage artisanal fishing operations off of the coasts of Peru and Ecuador. Conservation initiatives recognizing the environmental impact of fishing in this zone have been promoting reduction of seabird bycatch by educating local fishermen. Despite these conservation efforts, the results from my thesis suggest a continued population decline for this critically endangered species and additional mitigation may be needed for the persistence of the waved albatross.</p>

Radio resource management (RRM) is an important component of a mobile wireless network that efficiently utilizes the limited radio resources such as spectrum, transmission power, and network infrastructure. Unfortunately, current RRM schemes do not support cooperative multiple point (CoMP), a promising technology that extends coverage, increases capacity, and improves the spectral efficiency of the next generation broadband network, i.e., 4G network. Specifically, to coordinate with CoMP, a RRM scheme should be aware of three main properties of CoMP - cooperative transmitting information, coordinated scheduling transmission, and single interference noise ratio (SINR) improvement. However, few of the existing RRM schemes consider these properties, since they were designed based on the conventional mobile data networks without CoMP technology. In this dissertation, I present a series of new CoMP aware RRM schemes for ensuring users' throughput and maximizing network capacity in an integrated PON-OFDM network, which is a norm of the 4G network and can best implement the CoMP technology. I call the PON-OFDM network with CoMP a CoMP Network (CoMPNet). I provide two classes of RRM schemes for two practical CoMP technologies, cooperative transmission (CT) and coordinated scheduling (CoS), respectively. In the first class, I propose two groups of RRM schemes using the CT technology. In the first group, three OFDM-TDMA based RRM schemes are designed for three different users' moving speeds. The objective of these schemes is to minimize time slot consumption. The RRM schemes in the third group are contrived for an OFDM-FDMA based CoMPNet. I provide four linear programming (LP) based optimal schemes, one for minimizing bandwidth usage, one for minimizing transmission power consumption, and two for balancing resource costs. An optimized resource allocation solution can be obtained by flexibly choosing one of the schemes according to network load. In the second class, I present a sub-optimal RRM scheme for an OFDM-FDMA based CoMPNet. The CoS technology is applied for ICI mitigation. I formulate the system optimal task into constrained optimization problems for maximizing network capacity. To improve the computation efficiency, fast yet effective heuristic schemes are introduced for divide-and-conquer. The proposed heuristic schemes are featured by CoS based timeslots/subcarriers assignment mechanisms, which are further incorporated with intelligent power control schemes. Through simulations, I study the proposed RRM schemes performances and discuss the effect of the CoMP technology. The performance benefits of CoMP on bandwidth saving and capacity increasing are shown by comparing the new schemes with the conventional schemes without CoMP.

In recent years, significant advances have been achieved in communication networks and electric power systems. Communication networks are developed to provide services within not only well-connected network environments such as wireless local area networks, but also challenged network environments where continuous end-to-end connections can hardly be established between information sources and destinations. Delay tolerant network (DTN) is proposed to achieve this objective by utilizing a store-carry-and-forward routing scheme. However, as the network connections in DTNs are intermittent in nature, the management of network resources such as communication bandwidth and buffer storage becomes a challenging issue. On the other hand, the smart grid is to explore information and communication technologies in electric power grids to achieve electricity delivery in a more efficient and reliable way. A high penetration level of electric vehicles and renewable power generation is expected in the future smart grid. However, the randomness of electric vehicle mobility and the intermittency of renewable power generation bring new challenges to the resources management in the smart grid, such as electric power, energy storage, and communication bandwidth management. This thesis consists of two parts. In part I, we focus on the resource management in DTNs. Specifically, we investigate data dissemination and on-demand data delivery which are two of the major data services in DTNs. Two kinds of mobile nodes are considered for the two types of services which correspond to the pedestrians and high-speed train passengers, respectively. For pedestrian nodes, the roadside wireless local area networks are used as an auxiliary communication infrastructure for data service delivery. We consider a cooperative data dissemination approach with a packet pre-downloading mechanism and propose a double-loop receiver-initiated medium access control scheme to resolve the channel contention among multiple direct/relay links and exploit the predictable traffic characteristics as a result of packet pre-downloading. For high-speed train nodes, we investigate on-demand data service delivery via a cellular/infostation integrated network. The optimal resource allocation problem is formulated by taking account of the intermittent network connectivity and multi-service demands. In order to achieve efficient resource allocation with low computational complexity, the original problem is transformed into a single-machine preemptive scheduling problem and an online resource allocation algorithm is proposed. If the link from the backbone network to an infostation is a bottleneck, a service pre-downloading algorithm is also proposed to facilitate the resource allocation. In part II, we focus on resource management in the smart grid. We first investigate the optimal energy delivery for plug-in hybrid electric vehicles via vehicle-to-grid systems. A dynamic programming formulation is established by considering the bidirectional energy flow, non-stationary energy demand, battery characteristics, and time-of-use electricity price. We prove the optimality of a state-dependent double-threshold policy based on the stochastic inventory theory. A modified backward iteration algorithm is devised for practical applications, where an exponentially weighted moving average algorithm is used to estimate the statistics of vehicle mobility and energy demand. Then, we propose a decentralized economic dispatch approach for microgrids such that the optimal decision on power generation is made by each distributed generation unit locally via multiagent coordination. To avoid a slow convergence speed of multiagent coordination, we propose a heterogeneous wireless network architecture for microgrids. Two multiagent coordination schemes are proposed for the single-stage and hierarchical operation modes, respectively. The optimal number of activated cellular communication devices is obtained based on the tradeoff between communication and generation costs.

Namibia’s community based natural resource management program (CBNRM) integrates local participation in rural development and biodiversity conservation. This effort was launched through key legislation that devolved the right to manage wildlife and other renewable resources on communal lands from the state to community level conservancies. Local participation is dependent upon the capacity of the locals to self mobilize and establish conservancies, plan and implement their programs, and monitor and evaluate their progresses and impacts. Accordingly, this study examines the role of capacity development (CD) in CBNRM, particularly its processes, products, performance, and permanence at the individual, organizational (conservancy), and community levels. The research was carried out using interviews and participatory self-assessment exercises with various conservancy stakeholders. This study uncovers why and how capacity development has to be based on local realities and aspirations where capacity users need to have ownership of the process through partnerships with service providers in order to enhance endogenous capacity. However, such notion of “partnership” between CD stakeholders is challenging to translate into reality in the face of power imbalances, where government and NGOs are continuously influenced and coerced by donor interests, where NGOs are considered stronger than the government because they control more financial and human resources, and where conservancies tend to report upwards to NGOs and government instead of their constituents. Moreover, this research reiterates that CD has to be holistic enough to incorporate individual, organizational, and community level changes in order to create sustainable capacities and prevent problems of elitism, manipulation, and dependency on few individuals. With respect to CBNRM, the research argues that its basic premise of diversifying rural livelihoods using incentives to bring about sustainable resource management can only be achieved when conservancies have the capacity to create representative and participatory democratic processes, and when they are able to generate equitable and reliable tangible benefits with manageable costs to their constituents. As seen in this study, when such governance and benefit sharing structures are in place, they enhance local participation by promoting political empowerment, trust, ownership, and positive attitude towards living with wildlife. However, if such conditions are not met, local participation is reduced, while intra-community conflicts from marginalization to nepotism and members’ dissatisfaction and disinterest are inevitable.

The purpose of this thesis is to analyse the evolution of New Zealand�s Quota Management System (QMS) for marine fisheries. Analysis is performed using institutional theory and methodology. A broad review of institutional theory is made. In contrast to neoclassical economic theory, of which institutionalists have been a major voice of dissent, institutionalism stresses a holistic approach to policy analysis. An understanding of the the forces for institutional change and the structure of that change are the primary focus of institutionalism. An institutional framework for understanding the common pool nature of fishery resources is adopted. This highlights how the physical and technical characteristics of the resource and related decision-making arrangements influence the patterns of human interaction that determine the outcomes of a management regime such as the QMS. It is shown that the QMS was adopted in 1986 to address the biological crisis that had occurred because of past open access management policies. The fiscal crisis and the economic ideology prevailing at the time were also influential in promoting the QMS. The system was not able to be expanded as was intended because of a series of challenges from Maori disputing the Crown�s right to fishery resources. The Deed of Settlement signed in 1992, has supposedly settled Maori claims to commercial fisheries and allowed expansion of the QMS. Assessing the QMS using the institutional framework developed, showed the strong influence that neoclassical ideology has played in determining the outcomes achieved. Inadequate information concerning biophysical, social and economic implications of fishing constrain the ability of the QMS to successfully manage the resource. Inconsistencies and inadequacies in the legislation are only just being addressed as part of a comprehensive legislative review process. The future development of the QMS is also addressed in terms of the likelihood of cooperative common property management regimes being adopted. The common pool nature of the fisheries makes common property management regimes preferable. Cooperative community cultures are claimed by institutionalists to improve the outcomes achieved in common property regimes. There was considered, however, to be only limited potential for cooperation within the current institutional structure for New Zealand�s fisheries. Although the changes of the legislative review appear to be making some progressive changes, the diversity of interest groups and the prevailing western culture are seen as potential impediments to a comprehensive cooperative regime.

The construction industry forms an important part of national economies from the United States and the United Kingdom to Australia and Singapore. The industry is a large employer and is described as being traditional, fragmented, adverse in culture and poor in quality. It has a specific problem of two types of production, namely design and actual construction. Human resource issues are neglected as the industry operates by project management, which does not allow for systematic and long term organisational development. These factors, in short, have caused the industry to remain disintegrated. / The purpose of this research was to investigate how a process of integrating internal and external customers and technology could be developed and implemented in the building components industry. The research problem revolved around the customer orientation concept, which other industries claim to have implemented successfully. The research problem was conceptualised as lack of internal and external customer orientation. / The research was carried out in a company called Eastern Pretech Pty. Ltd in Singapore, and more particularly in its precast concrete division, which is a unit of analysis employing some 80 staff members and 300 workers. The sequential order of work-design, production, delivery and installation- had created disintegration in the approach to external customers. The products of the division included design, manufacturing and delivery/installation of structural frames of buildings, including columns, beams, slabs and walls. / For the purpose of undertaking the investigation the researcher developed an exploratory case study strategy, which was justified as being an inquiry into unknown phenomena where no similar studies had been made in the precast concrete industry or in the construction industry in general. Because of the exploratory nature of the inquiry there were no hypotheses to be tested, but rather research questions to be answered. / The researcher justified the use of participant action research for the purpose of the investigation. The research design was divided into conceptual and action research method stages. The conceptual stage included the past experience and interest of the researcher and well as the literature review, and the action research method stage included the case study analysis and thesis writing. The researcher was a participant observer when carrying out the case research. / In conclusion, the exploratory case study strategy resulted in rich data, which showed evidence of change occurring and integration happening. The action research case study was concluded in a real life situation, where the uncertainty of outcomes and almost impossibility of forecasting results allowed the researcher to use imagination in constructing new concepts and theories using the participant action research method. The results included the development of an ICO model which can form the basis for further investigations. The research made contributions to marketing and other aspects of management- in particular to customer orientation, total quality management and the organisational development literature in the area of construction. The research also fulfilled the dual goals of action research by contributing to knowledge and practice. / Thesis (PhDManagement)--University of South Australia, 2002.

Abstract This thesis explores the management of human resources (HR) in five star hotels located in a developing country (Malaysia). This study is particularly relevant to the hotel industry, known for its traditionally poor HR practices (e.g., a lack of employment security, training, and career development opportunity, low levels of employee involvement and an increasing number of casual employees who are paid hourly). These practices are often perceived as a solution to high labour costs and fluctuating demand prevalent in the hotel industry. However, it is often only "non-managerial" employees who are affected by poor HR practices, as more sophisticated approaches to HR practices are often taken with regard to managerial (strategic) level employees. HR practices system differentiation (HRPSD), or HR architecture, involves having more than one HR practices system within an organisation. HRPSD has been criticised in the hospitality management literature for the poor HR practices in the management of non-managerial employees, however despite this criticism, it is widely practiced by the industry. The continuation of HRPSD practices in the hotel industry suggests its importance to better understand, research and study. The aim of this research is to gain an understanding of HRPSD in a hotel industry context, and to better understand the immediate effects of such practices. While the existing literature concerning HR architecture in other industries provides some discussion of HRPSD, research and study of the concept focusing on the hotel industry is essential in providing a detailed explanation of the effect of this phenomenon, as HR practices between industries may vary. Central to this study, is an investigation of the nature of HRPSD, identification of HR intermediate outcomes, and the effects of HRPSD on hotel employees. Studying the effect of HRPSD on employees is important because employees are known to be a hotel organisations‟ most important resource. Developed based on the literature of SHRM and HR architecture, this study proposes a conceptual model that incorporates HRPSD in the SHRM model originally proposed by Schuler, Dowling, Smart, and Huber (1992). Guided by this model, this study seeks to answer the critical questions of “how organisations differentiate their HR practices systems” and “what are the corresponding HR intermediate outcomes?” A particular foci of this thesis relates to how the concept of a “strategic” (or managerial) job is conceptualised in the hotel industry, what the elements of HR practices systems in five-star hotels are, how and why hotel organisations differentiate their HR practices systems, what the HR intermediate outcomes of HRPSD are and how HRPSD relates to the identified HR intermediate outcomes. To answer these complex research issues, a multiple case research methodology is employed, utilising a series of in depth semi-structured interviews. This vi study focuses specifically on five-star hotels in Malaysia because HR practices vary among hotels of various sizes. The findings indicate a notable effect of HRPSD on employees‟ motivation, job satisfaction, organisational commitment and retention, and that excessive differentiation is not beneficial for a five star hotel. In this study only certain HR practices were found to be differentiated; selective staffing, extensive training, compensation and empowerment. HR practices that were applied to all employees without differentiation were a clear job description, orientation, employment security, objective performance appraisal, career development opportunity and effective communication. In addition, this study also provides a clear definition of the strategic job in the hotel industry, and demonstrates the importance of HR practices integration and the influence of internal and external environments on the formation of HR strategy. This research contributes to theory as well as hotel sector policy and practice. Theoretically, it has identified how HRPSD links to firm performance (in Malaysian five star hotels). In addition, it provides clear definitions and understanding of the strategic job concept as well as identification of HR practices system elements and their differentiation in five-star hotels. Furthermore, the theoretical framework developed can be useful for future quantitative studies which can test the model formulated in this study. For practitioners, the detailed examination of HR practices system elements and how they are differentiated may guide them in their future HR strategy formation.
