As a result, proteins found in the centre of the lens (the nucleus) are present for a lifetime. This tissue can therefore be used to examine major posttranslational events that take place in long-lived proteins. Age-dependent deterioration of long-lived proteins in humans may have wide-ranging effects on health, fitness and diseases of the elderly [1]. To a large extent, denaturation of old proteins appears to result from the intrinsic instability of certain amino acids, however these reactions are incompletely understood. In this thesis, to understand more about these reactions, the breakdown of peptides was studied under controlled conditions, typically at physiologically relevant pHs and with elevated temperatures used to promote the reaction. Significant truncation of long-lived proteins has been shown to occur in the aged human lens. In the case of α-crystallin, one notable feature of the sequences of two of the most abundant truncations (αA 67-80 and αB 1-18) was that sites of cleavage were adjacent to Ser residues. While the truncation of proteins at Asp/Asn residues via the formation of a succinimide ring has been well characterised, our understanding of the processes that enable truncation at Ser is incomplete. The first part of this thesis aimed at understanding the mechanisms behind this truncation. A secondary aim was to understand the mechanism behind the age-related racemisation of Ser residues seen in the lens, and determine if it occurs via a mechanism analogous to that seen with Asp residues. Model peptides based on the sequence of known Ser truncation sites in human α-crystallin were exposed to elevated temperatures at physiological pH. Non-enzymatic truncation at the N-terminus of Ser, similar to that seen in the aged-lens was demonstrated. A range of additional factors were also examined for their ability to promote truncation. The role of the Ser hydroxyl group was investigated and found to play an important role in truncation at Ser. Interestingly Ser racemisation was also observed under these conditions, and it occurred regardless of the presence of a free or blocked Ser hydroxyl group. This was at odds with our initial hypothesis that both racemisation of Ser and truncation the N-terminal side of Ser might be a linked process, occurring via formation of a cyclic tetrahedral intermediate. Another possible source of Ser racemisation was investigated by examining the potential of phosphoser (pSer) residues to form dehydroalanine (DHA) via beta elimination. While DHA was generated from a model peptide at physiological pH, the results in this thesis did not find any evidence of water adding to the double bond, thus ruling it out as a possible explanation for Ser racemisation in the lens. However the observed formation of DHA at physiological pH does provide a potential explanation for the extensive non-covalent cross linking seen in aged lens proteins. The second part of this thesis examined a range of modifications that can occur at a peptide N-terminus. Approximately 70% of soluble proteins in eukaryotic cells have an acetylated α amino group. One proposed role of this is that it protects the protein from a range of N-terminal modifications. However following age-related internal truncations, such as those observed at the N-terminus of Ser and other known truncations, the resulting protein fragments (with free amino groups) could then be subject to N-terminal degradation. Using model peptides based on human lens crystallin sequences, facile racemisation of N-terminal residues incubated under physiological conditions was demonstrated. It was shown to occur across a range of N-terminal residues, buffers and temperatures. Unexpectedly the racemisation rate of L-residues was almost twice that of D-residues but the reasons for this are as yet unclear. A novel mechanism to explain these findings, involving the formation of a Schiff base has been proposed. Racemisation of the N-terminal residue was also shown to render the peptides resistant to amino peptidase degradation, suggesting a protective role could be provided by this modification. The prevalence of this modification in the humans lens was then demonstrated using the integral membrane protein Aquaporin 0 (AQP0). By the age of 68, 13% of the N-terminal Met residue of AQP0 had racemised in the cortex, increasing to 28% in the nucleus which is the oldest part of the lens. Other N-terminal modifications studied included the degradation of model peptides via sequential loss of their N-terminal residues. Again it was shown to occur at physiological conditions using model peptides based on crystallin sequences, however further investigation revealed that it was more prominent in phosphate buffer. One potential mechanism involves phosphate buffer acting as a nucleophile. It is worth noting that phosphate buffer is present in the human lens and that this may still be a biologically relevant degradation process. Aged proteins demonstrating sequential loss of amino acid residues or “laddering” have been described in the literature [2]. The potential for proteins to degrade via loss of two amino acids at a time through a cyclic diketopiperazine (dkp) from the N-terminus was also investigated. A range of factors were considered and it was shown to be another potential degradation pathway for long-lived proteins which have a free amino termini. Peptides that have a penultimate Pro residue were particularly prone, with significant dkp formation occurring even at physiological temperatures. For peptides without a penultimate Pro, dkp formation was still observed for a range of peptides, but elevated temperatures were required. The final part of this thesis detailed the isolation and characterisation of a novel UV filter found in the lens of the thirteen-lined ground squirrel. The structure of this UV filter is of interest due to the lens of the thirteen-ground squirrel having a similar UV filter profile to that of the human lens. Characterisation by mass spectrometry and NMR spectroscopy revealed the likely structure to be an N-acetylated 3OH Kynurenine adduct with the incorporation of a proline. A potential structure has been proposed involving the formation of an imine bond between the proline and the 3OH Kynurenine.

One hundred and eight leaders participated in collaborative qualitative research aiming to help the organisation improve professional practice in the development of healthy and effective leaders. Structured conversations, storytelling and other participatory techniques were used to elicit the leaders’ own tacit knowledge to better understand the systemic health issues that they face. Viewing the organisation through complex living systems was found to be a useful framework to explore four cycles of action research inquiry. An aspirational state of ‘optimal functioning’ was identified to assist a shift in leadership practice that emphasises the salutogenic (focus on health and wellness) rather than merely responding to the pathogenic (focus on disease and disorder). Participants co-generated their own theories of transformation, making tacit knowledge explicit through the development of six mapping tools that were designed to share newly found knowledge throughout the organisation. PAR effectively influenced both learning and change, contributing to the launch of three system-wide action interventions: (1) The Centre for Wellness, (2) The Leaders Care Network and (3) Mentoring Training. The result is a holistic approach to leadership development designed to improve the health and effectiveness of leaders across the organisation.

Informal conversation about teaching within university departmental contexts represents one way academics learn about university teaching. Such conversations also have the potential to more effectively link learning on formal professional development programs with teaching. As professional development of teaching is usually focused on formal courses, workshops and projects, informal conversation has not been investigated as a professional development strategy. The lack of substantial exploration of conversation as a professional development strategy was the impetus for the current study. This study investigated academics’ experience of informal conversation about teaching within their departments. Thirty academic staff working in different departments at an Australian research-intensive university were interviewed and the transcripts were analysed using grounded theory (Glaser & Strauss, 1967). The analysis revealed that academics were learning about many aspects of teaching from informal conversation with their departmental colleagues. Four elements of informal conversation were explored: the content of conversation, the purpose for which academics used conversation, the context which influenced conversation and the relationship between conversation and formal (course-based) professional development. In summary, academics’ conversations were about topics that included students, assessment, curriculum and evaluation, with their purposes ranging from venting their frustrations, and reassuring themselves, to managing, improving and evolving their teaching. The investigation of the role of contextual influences on informal conversation about teaching yielded a theory for the nature of conversation, based on ‘commonality’. In a context which provides variable support for teaching, increases in commonality between academic colleagues are associated with increases in frequency and usefulness of their informal conversation. The theory of commonality and the description of the nature of informal conversation derived from this study are used to show how informal conversation can enhance professional development.

MHC class I and class II genes encode cell-surface molecules that are involved in antigen presentation to T cells. This thesis describes the characterization of the MHC in the Tasmanian devil (Sarcophilus harrisii), the largest remaining carnivorous marsupial in the world which is currently under threat of extinction due to a contagious cancer – devil facial tumor disease (DFTD). In order to provide a better understanding of the devil immune system, the genomic organization, gene content, and genetic variation within the devil MHC, particularly within the class I and II regions, were investigated in this project. Four genomic regions containing devil MHC class I and II genes were assembled and annotated using bacterial artificial chromosome (BAC) contigs. All these regions were physically mapped to the same area on the long arm of devil chromosome 4, indicating the genomic location of the devil MHC. Thirty-four genes and pseudogenes were identified, including five class I and four class II (one ɑ chain and three β chain) loci. Comparison between two haplotypes from two individuals revealed three genomic copy number variants within the class I gene region, causing differences in the number of functional class I genes among individuals. Eleven microsatellite markers located adjacent to class I or II genes were developed to facilitate MHC typing in devils. The level of genetic variability within the devil MHC is low. In 60 individuals from across Tasmania, only three, six and three alleles were found at the three class II β chain loci Saha-DAB1, 2 and 3, respectively, exhibiting very limited polymorphisms in the peptide-binding regions. The sole class II α chain gene (Saha-DAA) appeared to be monomorphic. In contrast to other examined marsupials, the devil has only one functional class II gene family, which further restricts its class II diversity. The low MHC variability may have led to increased vulnerability of the devil to evolving pathogens, emerging infectious diseases and environmental changes. For the long-term survival of this iconic species, it is crucial to ensure that further losses of MHC allelic diversity do not occur. Skin graft experiments showed that low MHC diversity may have contributed to delayed allorejection in the devil. However, it was also found that all skin allografts were rejected by Day 21 after transplantation even between MHC-identical individuals, suggesting that allorecognition in the devil likely involves not only major but also minor histocompatibility antigens. These results indicate that low MHC diversity alone does not fully explain the transmission of DFTD across the devil population, and that the tumor is likely to be actively evading the host immunosurveillance. The fundamental work on MHC characterization presented in this thesis has improved our knowledge on devil MHC genes at the genetic, genomic and functional levels, and represents an important step in understanding the role that the MHC has played in the spread of DFTD Sun, 01 Jan 2012 00:00:00 GMT http://hdl.handle.net/2123/9162 2012-01-01T00:00:00Z http://hdl.handle.net/2123/9131 Title: Bridging two worlds: from industry to school Authors: Green, Annette (Annette May) Description: This thesis was digitised for the purposes of Document Delivery.

Although it is known that the rates of morbidity are much higher among Aboriginal people compared with the non-Aboriginal population, the participation rates of Aboriginal people in disability services are under-representative. Various authors have examined these phenomena from the view point of Aboriginal people who may be interested in using disability services. However, there is limited understanding on the views of non-government and Aboriginal and non-Aboriginal workers of disability services about the factors that influence the participation of Aboriginal people in disability services. This study aimed to help fill this knowledge gap by achieving the following three research objectives: 1. Identify how and when the participation of Aboriginal people in disability services was identified in documented policy. 2. Identify and describe the factors that influence the participation of Aboriginal people in disability services as perceived by Aboriginal and non-Aboriginal employees in two NSW Government Department of Ageing, Disability and Home Care funded disability services. 3. Develop an Explanatory Framework that adequately encapsulates and represents the factors identified in this study as influencing the participation of Aboriginal people in disability services. One Aboriginal community controlled organisation and a generic disability organisation were the sites for investigation. Objective one was achieved through a critical historical analysis of policy documents developed by the governments, one Aboriginal community controlled organisation and one generic disability organisation. A rigorous electronic and manual search of publications spanning three decades from 1981 was undertaken. This analysis demonstrated that the disability services sector’s strategies to accommodate the needs of Aboriginal people with a disability have made a limited impact on the service participation rates and have been hampered by Eurocentric models of disability and research. A conceptual framework is proposed to assist disability researchers and policy analysts working with Aboriginal people with a disability. The conceptual framework brings together the strengths of both the International Classification of Functioning, Disability and Health and the Indigenous Standpoint Theory. The second objective was achieved via a situational analysis of transcripts of interviews, focus groups and field notes that were conducted with Aboriginal and non-Aboriginal paid employees of the same government funded organisations. Twelve factors that influenced the participation of Aboriginal people in disability services were identified from the data. Consistent with objective three, an Explanatory Framework was developed which illustrated the relationships between these factors. This framework demonstrated that the factors that influence the participation of Aboriginal people in disability services are inter-dependent historically, culturally and institutionally. The identified factors and explanatory framework are used to guide recommendations for future research, policy development and service provision in the sector.

This thesis documents an investigation of thyroid hormones and the regulation of thyroid hormones in an animal model of neuropathic pain. The technique used in this model, Chronic Constriction Injury (CCI), produces an injury that creates an inescapable mechanical and inflammatory stress for the rat. Various forms of stress, and in particular unavoidable stress, have been shown to alter thyroid hormones in both rats and humans. This rat model has been developed to more closely resemble the neuropathic pain state in humans where a proportion of patients develop a syndrome of social and behavioural changes, which has been termed ‘disability’. As well as demonstrable sensory dysfunction, as a result of the nerve injury, a sub-population of the rats exhibit altered patterns of complex social behaviours. The results of three experiments are presented. In each case a cohort of rats was subjected to the same procedure – Chronic Constriction Injury – and changes in social behaviour measured using a Resident-Intruder test. Rats were assigned to one of three groups based on the results of the behavioural test: No Disability (ND), Transient Disability (TD) or Persistent Disability (PD). In experiment 1, documented in Chapter 4, peripheral thyroid and corticosteroid hormones were measured pre and post-CCI together with Thyroid Stimulating Hormone (TSH) levels. Results for the three different behavioural groups were compared. In experiment 2, documented in Chapter 5, RNA was extracted from the hypothalamuses of rats sacrificed six days post CCI. Relative gene expression was determined for a number of factors involved in thyroid hormone and corticosteroid regulation. In experiment 3, documented in Chapter 6, at the end of the experimental period, seven days post-CCI, the rats were perfused to remove blood and the brains preserved in paraformaldehyde. The hypothalamuses were examined using immunohistochemical techniques for evidence of differing protein expression for molecules involved in thyroid hormone regulation. Summary of Findings. Behavioural Testing (Chapter 3): The results of behavioural testing for the experimental groups of animals used in this study conform to those previously found using this model (Monassi et al., 2003). Based on previously derived criteria 70% were classified as ‘No Disability’ (ND); 10% of the rats and were classified as ‘Transient Disability’ (TD) and 20% of rats were classified as ‘Permanent Disability’ (PD) animals. Rats classified as PD have significantly decreased levels of Dominance behaviour on days 1-3 and 4-6 post-CCI when compared to ND rats whereas TD rats have decreased Dominance behaviour on days 1-3 only. Pre-CCI behaviour is not predictive of post-CCI behavioural change. Peripheral Thyroid Hormones (Chapter 4): When compared to pre-injury levels, the mean total thyroxine (TT4), total triiodothyronine (TT3) and free thyroxine (fT4) levels were significantly decreased in the PD rats whereas the post-injury levels of these hormones did not change in the ND and TD rats. There was no difference between groups in mean free triiodothyronine (fT3) and thyroid stimulating hormone (TSH) levels pre and post-injury. The pattern of secretion of hormones differed in the ND and PD rats over the six days post-injury. In the ND rats, there was a surge in TSH post-injury and thyroid hormone levels were maintained at pre-injury levels. However, in the PD group, the TSH response was delayed, blunted and inadequate as thyroid hormone levels decreased. There was a significant correlation between decreased Dominance behaviour and both TT4 and fT4 but no correlation with TT3 or fT3. Peripheral Corticosteroids (Chapter 4): There was an increase in corticosterone in all animals post-CCI. The Transient Disability rats showed the greatest increase in corticosteroid and this was significantly different to the other two groups of rats. There was no difference in post-CCI corticosterone levels between the PD and ND rats. Hypothalamo-pituitary-thyroid (HPT Axis) regulation (Chapters 5 & 6): RT-qPCR measurement of relative mRNA expression in the hypothalamus showed that there was no difference between No Disability, Transient Disability and two groups of control rats (Behavioural Controls (BC) and naïve group caged controls) for Thyrotrophin Releasing Hormone (TRH), Thyroid Hormone Receptor β (TR β), Deiodinase 2 (Dio2) and Deiodinase 3 (Dio3). Compared to the BC rats, the Permanent Disability rats had significantly decreased relative expression of TRH and Deiodinase 2 and significantly increased expression of Deiodinase 3 mRNA. Immunohistochemical techniques used to label TRH, TR β, Deiodinase2 and Deiodinase 3 protein distribution in the Paraventricular Nucleus (PVN) of the hypothalamus showed significantly fewer immunoreactive profiles for Deiodinase 3 and TRβ in the group with changed behaviour (PD group) compared to the Behavioural Control rats. These differences were shown to be specific for the sections of the PVN where the hypophysiotrophic TRH secreting neurons are known to be primarily located. Hypothalamo-pituitary-adrenal (HPA axis) regulation (Chapter 5): RT-qPCR measurement of relative mRNA expression in the hypothalamus showed that there was no difference between ND, TD, PD and Behavioural Controls rats for Corticotrophin Releasing Hormone (CRH), Glucocorticoid Receptor (GR) and Vasopressin. Compared to the Behavioural Controls, group caged Control animals had significantly increased relative expression of CRH and Vasopressin mRNA.

In cases where the seafloor depth is greater than the DVL bottom-lock range, localising between the surface, where GPS is available, and the seafloor presents a localisation problem since both GPS and DVL are unavailable in the mid-water column. Reliance on acoustic tracking methods such as Ultra Short Base Line (USBL) requires a ship to track the vehicle, while Long Base Line (LBL) requires the setting up of an acoustic transponder network. These methods provide bounded error position localisation (~10m) of the underwater vehicle, but inhibits the flexibility and autonomy of the vehicle due to tending or set-up requirements. Proposed alternatives to these include combining GPS on the surface, navigation-grade IMU, the DVL water-track mode and a vehicle model to reduce the dead-reckoning error, although results show that this error is still not competitive with acoustic tracking methods after approximately 10 minutes of descent. Often ocean depth requires hours of descent without GPS or DVL, thus acoustic tracking methods are preferred. This work proposes a solution to localisation in the mid-water column that exploits the fact that current profile layers of water columns are stable over short periods of time (in the scale of minutes). As demonstrated in simulation, using observations of these currents with the ADCP (Acoustic Doppler Current Profiler) mode of the DVL during descent, along with sensor fusion of other low cost sensors, position error growth can be constrained to near the initial velocity uncertainty of the vehicle at the sea surface during a vertical dive. Following DVL bottom-lock, the entire velocity history is constrained to an error similar to the DVL velocity uncertainty. When coupled with a tactical-grade IMU and Time Differenced Carrier Phase (TDCP) GPS measurements, approximately 15 m/hr (2 sigma) position error growth is possible prior to DVL bottom-lock, and 6.5 m/hr (2 sigma) position error growth is possible following DVL bottom-lock. The method is demonstrated using real data from the Sirius AUV coupled with on-bottom view-based SLAM (Simultaneous Localisation and Mapping), without the use of an IMU. Horizontal localisation in the mid-water zone is also explored using an extension to the water-layer framework. The layered water currents are extended to include horizontal gridding, while the ADCP sensor is remodelled to use beam coordinates to exploit horizontal observation. The water current vector field is modelled as correlated spatially through neighbourhood least-squared constraints. Simulations illustrate the performance possible with this method, and results from real data validate this approach. In order to minimize the dead-reckoning error during mid-water zone transits, a novel method to incorporate Inertial Measurements and the constraints of a drag-based vehicle model is outlined. The drag-based Vehicle model uses the water current velocity estimates from the ADCP aiding method, while also accounting for the error from the Vehicle parameters given a prior system identification. Due to the redundant observations of motion from the IMU and DVL when available, there is potential for further improvement in estimates of the Vehicle parameters. Simulations are undertaken to assess the advantage of incorporating a vehicle model, and application on real data from the Sirius AUV validates this method.

However, shrimp farming is generally technically inefficient and probably generates too much pollution. To encourage the sustainable development of the Vietnamese shrimp industry, there is a need to improve the productivity of shrimp farms and at the same time to reduce the wastewater pollution generated by shrimp farming. The thesis has two aims: (1) to estimate the efficiency of shrimp farms in the Mekong Delta of Vietnam, with a particular focus on the productivity effects of pollution, and (2) to use experimental economics to investigate policies that could be used to mitigate the wastewater pollution impacting shrimp farms. Overall farmers are found to be inefficient, suggesting farmers are using more inputs than necessary to produce a given output level. Surprisingly, the average extensive (i.e., less capital-intensive) farm is found to be more efficient than the average intensive and semi- intensive (i.e., more capital-intensive) farms. Furthermore, downstream farms are found to be less efficient than upstream farms, suggesting that wastewater pollution influences shrimp farming productivity and results in a negative externality. Evidence from lab-based experiments suggests that the incentives provided by a monitoring and certification agency are not sufficient to promote the full cooperation of shrimp farmers to solve the wastewater pollution problem. However, full cooperation was achieved by providing farmers with an opportunity to communicate. In both cases, self-governance of shrimp farmers was found to be highly effective. The results suggest that community-based management is worthy of further investigation as a possible solution to sustainable development of the shrimp industry in Vietnam.

A public transport demand model is constructed to incorporate two factors that have been highlighted in the literature of travel behaviour but still under-researched, which are: (i) the temporal effect of demand adjustment; and (ii) the land use characteristics of the built environment. The research gaps in previous applied pseudo panel data research including estimation techniques and issues involved with the applications to public transport are identified and addressed in this study. The pseudo panel approach allows for the identification of long-term demand changes using repeated cross-sectional data, which are collected at an individual level with detailed travel-related information and geographical information. This study constructs static and dynamic pseudo panel data models to analyse public transport demand in terms of its associations with price, socio-economic factors,level of public transport service, and land use factors. The research findings identify the significant determinants of public transport demand in the SGMA, with a distinction between short-run and long-run demand elasticities. This suggests a timeframe of 2.13 years is required to reach the long-run demand equilibrium. The estimated demand elasticities are used to forecast demand for the SGMA with validated results supporting the applicability of the public transport model based on the pseudo panel data. The main contribution of this thesis is the identification of long-run public transport demand elasticities using a pseudo panel dataset created from existing repeated cross-sectional household travel survey data which uses more individual information than aggregate data. This approach enables a longitudinal analysis in the absence of genuine panel data, and this in turn provides important implications for urban public transport planning and policy formulation.

Findings from work based in the economics and behavioral theories of the multinational enterprise (MNE) both acknowledge that FDI is not a point-of-time decision but a gradual process that yields important changes over its duration. However, these competing traditions both fall short when attempting to portray the actual process by which FDI location decisions are made by managers in MNEs. This gap has been recently attributed to two interrelated limitations. Firstly, level of analysis concerns have artificially separated managerial decision-making processes from the organizational and environmental structures within which they are made. Secondly, because of the complexity inherent in the FDI location decision environment, the study of these decisions has not taken contextual factors into consideration. This study addresses three important questions in order to build our understanding of the FDI location decision-making processes: (1) What are the decision-making processes that lead to FDI location choice? (2) What is the impact of contextual variables on FDI location decision-making processes at different levels of analysis, and are there any patterns of variation in decision processes under different decision conditions? (3) What factors drive final FDI location choice, and can a useful framework or theory be developed that links FDI location decision-making processes and context to drivers of FDI location choice? In order to address level of analysis concerns, the study places the manager at the center of the FDI location decision in modeling and in research, a strategy recommended by an emerging stream of behavioral-focused international business research (Aharoni, 2010; Buckley et al., 2007; Devinney, 2011). By examining FDI location decisions from the perspective of the managers who implement them, it is possible to clarify the nature of processes that lead to FDI location choice, and identify the impact of different elements of decision maker, firm and environmental context on such processes. The conceptual framework builds on Aharoni’s (1966) pivotal research while incorporating findings from broader behavioral managerial decision models and international business research. The framework is based on the assumption that FDI location decision-making processes and final choice are contingent upon interactions between the environmental, firm and decision maker context under which the decision is made. The research was undertaken in three phases. Phase 1 included a literature review that covered research on the MNE, internationalization, and decision making. The findings of the review identified key aspects of FDI location decision context and led to the development of an initial contingency framework of strategic decision making. Phase 2 consisted of an exploratory case study of twenty four FDI location decisions. The initial contingency framework developed during the literature review was used during this stage to identify the relationship between decision-making processes and contextual variables at the case decisions. By drawing on results from the exploratory research, an initial conceptual model and a set of propositions were developed. In Phase 3, twenty case studies were theoretically sampled from a pool of MNEs of varying size and parent-country nationality within the knowledge-based industries. The data collection and analysis followed a process, event-driven approach to case study research involving the mapping of key sequences of events as well as within- and cross-case analysis. The results identify the key elements of the decision process that explain FDI location behavior and develop a framework that links them together and makes them sensible. The four key elements of the FDI location decision that comprise the framework include: (i) the process, (ii) the context, (iii) patterns, and (iv) location. Research findings show the FDI location decision process as comprising of five broad stages, the content of each driven by a dynamic and evolving interpretation of maximum subjective expected utility. Utility preferences are identified as the consequence of shifting and opaque goals, founded upon imperfect information, operating in an environment marked by uncertainty. Five variations in the overall orientation of utility at case decisions, classified in the study as ‘decision rules,’ proved to be more useful predictors of decision-making behavior than traditional notions of bounded rationality seeking rent extraction and profitability. Decision processes were found to vary in five prototypical patterns, according to clusters of contextual variables that together moderated the level of decision-maker autonomy, hierarchical centralization, rule formalization, commitment to strategy, and politicization of the decision. Patterns are described as FDI location decision-making models, and proposed as an initial step towards the development of a taxonomy of FDI location decision-making processes. Because of the dynamic and staged nature of the process, findings showed that factors that were important at one stage of the decision were not as important at the next. As such, the task of identifying universal drivers of FDI location was deemed an unfeasible one. In place of universal drivers, the initiating force of the investment, the purpose of investment and information sources and networks are identified as the key context-specific determinants of location in FDI decisions. Bounded by uncertainty, chance, the dynamics of the process and decision-maker effects, each of these aspects of the decision served to limit the possible consideration set for investment, and formed the value basis and measures from which to select the most attractive location choice. Despite the contextual differences in these drivers, however, the study revealed a strong pattern that showed that the importance of specific location considerations differed in much the same way across case decisions. During the first stage of case decisions primarily strategic aspects of locations were considered; during the second, considerations relating to the system; operational concerns in the third; implementation concerns in the fourth; and added value factors in the final choice. How each of these concerns was interpreted to reach final location choice differed according to the drivers mentioned previously, although the patterns were the same. This study develops a contingency framework for examining the FDI location decision-making processes of MNEs under different operating conditions. By identifying the four key components of the FDI location decision, their interrelationships and many sources of variance, this thesis shows that despite its complexity, the FDI location decision is amenable to useful conceptual structuring. From an academic standpoint, the framework answers Aharoni’s most recent call to action in ‘Behavioral Elements in Foreign Direct Investment’ (2010) by developing a replicable structure within which to think about incorporating managerial decision models and context into the theory of the MNE. These findings enhance understandings of decision making at MNEs, reconcile a number of inconsistencies between opposing perspectives of MNE theory, and thereby update extant theory so that it has greater relevance in today’s diverse international business environment. From a managerial standpoint, the thesis helps managers to recognize the opportunities and limitations posed by different aspects of decision context so that they are able to tailor their FDI location decision strategies to best suit their needs. Finally, from the perspective of policy markers, research findings provide great support for the use of investment attraction schemes through the use of targeted location marketing and investment incentives.   Description: Doctor of Philosophy (PhD) Fri, 01 Jun 2012 00:00:00 GMT http://hdl.handle.net/2123/9062 2012-06-01T00:00:00Z http://hdl.handle.net/2123/9056 Title: Protecting China's cultural heritage : a legal and policy approach Authors: Gruber, Stefan Description: This thesis was digitised for the purposes of Document Delivery.

The information services that deliver this layer to the urban actor (particularly pedestrians) will soon be ubiquitous and using those services a normal and integral part of the urban experience; more than an optional and utilitarian adjunct to it. The urban setting for these services prompts the question as to whether urban designers should be playing a role in their design and development; a role that seems conspicuously absent from current services. This thesis explores mechanisms which might facilitate a greater role for urban design by seeking ways in which the information architecture that underpins these information services might better reflect the qualities and complexities of urban space that urban designers recognise and value. The work of a range of prominent urban design thinkers is reviewed for ideas, constructs and elements that can be incorporated into an enriched information architecture which could in turn deliver information services that do justice to the depth and complexity of the urban environment. Technologies and standards associated with the ‘semantic web’ are identified as those which might best accommodate an appropriate information architecture; in particular, the ability to reflect the network characteristics of urban space viewed as a multi-dimensional graph of interconnected nodes. This view of urban space is contrasted with the relatively flattened view offered by global geo-spatial capability. An information model is built (only one of many possibilities) and validated using a limited test area in central Sydney. Practical and institutional issues which may impinge on the realisation and deployment of such a model in a real world setting are briefly considered in an appendix.

Abstract: Background Ethnicity and culture have an impact on sexual attitudes and behaviours of individuals and communities. Immigrants from different ethnic groups differ in sexual values, and culturally prescribed attitudes and behaviours have been found to contribute to sexual health inequalities among immigrant populations. Research has also confirmed the importance of examining the relationship between sexuality and the culture change process (acculturation). Indians belong to the world’s second most populous country and constitute one of the largest immigrant communities in Australia, the USA, UK and Canada. In 2011-12, India was Australia’s largest source country of migrants. Yet there is a paucity of scientific information about the effects of acculturation on sexuality and sexual health among Indian immigrants and most of what we know is based on research that has a number of serious conceptual and methodological shortcomings. The present study addressed this knowledge gap by exploring the psychosocial and cultural dimensions of sexuality and sexual health among a community-based sample of Indian men living in Australia. Unlike much of the previous research, which conceptualised and measured acculturation as a unilinear (assimilation) and unidimensional (behavioural) phenomenon, it adopted a bilinear, multidimensional model of acculturation. Aims The present study had three broad aims: • To explore sexual perceptions, attitudes and behaviours of Indian immigrant men living in Australia. • To explore the help-seeking attitudes of Indian immigrant men for sexual health • To examine the effects of acculturation on sexuality of Indian immigrant men living in a multicultural society (Australia). Method The project used a sequential, mixed method design. In Stage 1, qualitative data were collected from 21 participants in five focus groups. Findings from this stage were analysed both in their own right and in order to identify topics for further investigation. The group discussions were tape-recorded and transcribed and a thematic content analysis was performed. In Stage 2, 278 Indian men completed an online survey that used a 100-item questionnaire. It included a number of validated tools for measuring multidimensionality of acculturation, sexual attitudes and safe sex behaviour. The scales were assessed for their psychometric properties using the present study sample and were found to be comparable with previous findings. The survey data were analysed using non-parametric tests, where necessary, and the findings were presented in the form of descriptive and analytical statistics. Results The present study sample can be considered representative of Indian men in the general Australian population. A differential pattern of acculturation was found in the present study, with more men holding on to Indian values even though they tend to be bicultural in their behaviour and self-identity. A moderate (not too liberal or too conservative) pattern of permissive sexual attitudes was observed. Indian men’s belief in cultural values, relationship status and whether they masturbate or not were found to be significant predictors of permissive sexual attitudes. A view that sex is not only an important part of a person’s life but is also a unifying phenomenon between partners emerged from both focus group and survey data. A large proportion of Indian men expressed favourable/liberal attitudes towards masturbation and reported that they have masturbated at some point in their life. Using hands and tummy-down were the most common methods and erotic visual materials and self-thoughts (fantasising imagination) were the common stimulants for masturbation. The most frequently reported reasons for masturbating were to gain pleasure and to relax and relieve stress. About two-thirds of men who continue to masturbate reported one of three positive feelings (satisfying, healthy or attractive). Permissive sexual attitudes were the strongest predictor of positive feelings about masturbation. Indian men, irrespective of their relationship status, tended to engage in safe sex practice primarily by avoiding risky behaviours. While many were aware of HIV/AIDS, their knowledge of other common sexually transmissible infections (STIs) was limited. Data from both stages of the present study demonstrated that medical doctors (both general practitioners and specialists) were the main source of information and help for Indian men in regard to their sexual health. Conclusion The present investigation, which is first of its kind to be conducted among Indians, has established a baseline of scientific evidence to guide future research. The fluid nature of both sexuality and culture poses a considerable challenge to the scientific study of cultural effects on sexuality among any population. Even greater complexity exists in relation to Indians, who have experienced long periods of conflicting cultural influences on sexuality and whose social structure comprises a highly differentiated class and caste system. In an era of rapid economic and technological growth and modernisation, another challenge to socio-psychological studies on sexuality is the need to separate the effects of globalisation from those of acculturation. The findings also have a number of important implications for policy and for clinical practice in relation to the sexual health of immigrants in Australia. There could be considerable benefit, for instance, in developing a rapid values-assessment tool that would allow busy health professionals to look beyond a patient/client’s external behaviour or self-identity in order to facilitate holistic treatment of sexual problems. Limited knowledge about common sexually transmissible infections in Australia among Indian men has significant implications for policy changes around immigrants’ sexual health in Australia.
