Each of the seven investigations described in this thesis relate to the dental workforce in New Zealand (NZ). A variety of approaches were used to identify key trends in the NZ dental workforce, with a particular emphasis on comparing dental therapists, dental hygienists and dentists, and determining differences among dentists according to gender and immigrant status. Nation-wide postal surveys of dentists, dental therapists, and dental hygienists were undertaken to determine the working practices and career satisfaction of each type of oral health professional. A longitudinal analysis of the dentist workforce was then undertaken to describe changes in the NZ dentist workforce over time. An investigation of the job stressors and coping strategies of New Zealand dentists followed. This led to a qualitative study of the experiences of immigrant dentists in NZ, which sought further detail regarding the concerns raised by the Stress Study. The final investigation was a survey of the self-reported occupational health of NZ dentists, which built on from the results of the preceding studies. There were substantial differences in the working practices of male and female dentists. A greater proportion of female dentists had taken a career break of six weeks or more, usually to care for children. Larger proportions of women worked as employees or practice associates, and worked part-time. Women also planned to retire earlier than male respondents. Men were more active in continuing professional education and had higher career satisfaction. The career satisfaction of dental therapists and dental hygienists was similar, but dental therapists were much less satisfied with their income, and few felt a valued part of the dental community. Although many dental hygienists had taken substantial career breaks for childrearing, they were shorter than those taken by dental therapists. More therapists than hygienists planed to retire within the next 10 years. Over the nine-year period from 1997 to 2005, there was a significant increase in the number of women and overseas-trained dentists in the workforce. The proportion of dentists working in small towns decreased, and the percentage working part-time increased. The involvement of dentists in continuing professional development increased during that time. There was considerable variation in the number of stressors experienced by dentists, with overseas-qualified practitioners reported experiencing more stressors more frequently than did those trained in NZ. There were differences in the strategies used by male and female dentists to manage stress. Most immigrant dentists had found the dental registration examination process to be difficult and stressful. Uncertainty about the content of the examination and the high costs involved were key factors. Contact with practicing dentists during this time was found to be helpful. Overall, most dentists had good general health, but physical fitness levels were not ideal. The prevalence of hand dermatoses and musculoskeletal problems was high, with around 60% of dentists experiencing pain or discomfort. Workplace bullying was reported by 20% of dentists, and over 25% had experienced a violent or abusive incident. There is a need for ongoing monitoring of the workforce, particularly as the gender distribution (and societal trends and expectations) continues to change. Further support systems for immigrant dentists would be beneficial. Female and rural dentists also have unique circumstances and increased risk of professional isolation. Researchers and the professions will watch with interest the changes over the next decade as dual-qualified auxiliaries enter the dental workforce and public dental services are redeveloped.

The research problem that formed the basis of the investigation reported upon in this thesis relates to the challenges and opportunities that arise from the retention of World English Speaking (WES) student-teachers as they seek to gain entry into the teaching profession in Australia. Two key questions guided the exploration of this problem. How do the curriculum, teaching and assessment practices in teacher education assist and/or hinder WES student-teachers’ retention? What problems, if any, do they have in becoming Australian teachers? These are examined from the perspective of the WES student-teachers themselves, their teacher educators and the WES school teachers involved in supervising them during their practicum. Facing acute teacher shortage in some subjects and some areas in Australia, this research project investigated issues affecting retention of WES student-teachers to meet the requirements of Australia’s ethnically diversified school communities. Methodologically, this study used an evidence-driven, conceptually informed, valuerational approach to education research. A case study design provided the basis for a cross-sectional, retrospective, non-experimental plan which was used to collect and analyse data. The subjects, teacher educators and WES student-teachers were contacted via the university teacher education program; while WES school supervising teachers were selected from schools where WES student-teachers did their practicum. Theoretically it explores the power and limitations of current theorisation of teacher shortages in terms of global cultural flows, specifically the trans-national mobility of knowledge workers. This thesis situates their experiences in the context of current and projected teacher shortages as well as testing current theorisation about global cultural flows of people in terms of the trans-national mobility of knowledge workers. This thesis argues that while teacher-educators recognise the difficulties in engaging educationally with WES student-teachers, and WES student teachers and their supervising teachers are aware of and able to identify other difficulties they confront becoming “Australian teachers”, the possibilities for making productive responses is constrained by cultural as much as economic factors. / Doctor of Philosophy (PhD)

The Chinese tourists market has become the 4th largest inbound market for New Zealand in 2007; it also ranks 6th in terms of expenditure. Chinese visitors spent a total of NZ $352 million to the year December 2006, an average of NZ $3,340 per person (Ministry of Tourism, 2006). The latest statistics released from New Zealand Tourism Research Council show that 122,045 Chinese visited New Zealand by the year ended January 2008. These crucial statistics – market size, length of stay and average spend – indicate the necessity for the New Zealand tourism industry to understand and provide for Chinese expectations and requirements. Auckland is New Zealand's key gateway, and it is vital that Auckland provides a first good impression for the rest of country. Chinese travellers visit New Zealand with great desire and expectations of experiencing an exotic land. They expect Auckland, as the biggest city in New Zealand, to provide them with a memorable city experience in a developed country. The purpose of this research is to study Chinese tourists' expectations and travel experiences, with a particular focus on investigating whether Auckland can provide suitable services and experiences which match their requirements and expectations. The research will build on the study by Bull (1991) and Ryan (1995), which looked at supply demand relationships and at the tourism industry attempts to balance the supply with the actual demands. It will also build on work by Zhao (2006) and Qu (2006) which explored the dimensions of Chinese demand and distribution channel factors at both origin and destination. The goal is to establish which factors are adequate or inadequate. A synthesis of the demand supply situation will enable the development of recommendations. It is envisage that these recommendations could be adopted by local government and the tourism industry, either as actions or as improvements to policy. With regards to the purpose of this research, a qualitative method was decided as the most relevant approach. Qualitative methods are useful for revealing and understanding what lies are behind any phenomenon about which little is known. Grounded theory is a qualitative research method that was developed for the purpose of studying a social phenomenon, and to generate a theory relating to a particular situation (Strauss & Corbin, 1994). The historical bases of the grounded theory approach matches the aim of this research, namely to reveal the relationships between tourists and the tourism industry and to gain a better understanding of Chinese tourists' expectation and satisfaction, and the level of the service which the Auckland tourism industry provides to Chinese travellers needs to match the Chinese market and requirements of travellers. The interviews were conducted with both Chinese travellers and the Auckland tourism industry, including hotel managers, restaurant managers, gift/souvenirs shop assistants, tour guides, and so on. The research shows Auckland is not ready for Chinese market yet. This result comes from three aspects: firstly, most Chinese tourists do not have clear requirements or expectations of Auckland before they come to New Zealand. This is mainly because of the limited promotional materials available in China about Auckland. Secondly, Chinese tourists do not have many opportunities to get to know Auckland's attractions and activities after they arrive in Auckland. Auckland city is New Zealand's most popular urban tourism destination in terms of population and gateway function provides tourism facilities and services to Chinese tourists. However, the findings highlighted most Chinese tourists found Auckland's tourism attractions to be unattractive to them due to the language barrier and itinerary issues. Thirdly, the research also found Chinese tourists have been driven away due to lack of hotel accommodations in Auckland, especially in the shoulder or high seasons. Auckland's accommodation facilities are facing a challenge. The increasing domestic and international visitors' numbers and insufficient hotel accommodations will be the major problem for Auckland for the next decade. Most of the Chinese tourists who were interviewed expressed their hope of knowing more about Auckland, however, these hopes will go unrealised until the city provides better attractions and more services for them.

Doctor of Philosophy / Buyer-supplier relationships have been increasingly considered a critical part of contemporary supply chain management. In response to dynamic and unpredictable market changes, buyers and suppliers enter into cooperative relationships to pursue individual goals and joint goals for better economic and non-economic performance of the supply chain. On the other hand, cooperation between channel members is surrounded by uncertainty, which can create a detrimental impact on the performance of a supply chain. Previous research has focused on various aspects of uncertainty that could affect supply chain member behaviour. The present research contends that relationship behavioural factors play an important role in increasing or mitigating channel members’ perceived uncertainty in their supply or purchase decision-making. Specifically, the purpose of this research is to investigate the impact of retailer-supplier cooperation and retailer/supplier’s decision-making uncertainty (DMU) on retail supply chain performance from the perspectives of both the retailer and the supplier. A holistic model was developed as the theoretical framework for this conceptualisation. A sample of 202 retailers and 64 suppliers in the sporting goods retail business in Taiwan was used to separately test a number of hypothesised relationships by using structural equation modelling (SEM). The findings indicate that both cooperation and DMU are the key determinants of retail supply chain performance, including financial performance and non-financial performance (i.e., supply flexibility and customer service). Financial performance is positively affected by retailer-supplier cooperation and negatively affected by DMU in both the retailer model and the supplier model. The five dimensions of retailer-supplier cooperation (i.e. trust, guanxi, dependence, coercive power and non-coercive power) have significant effects on cooperation. However, apart from guanxi with the retailer/supplier, neither other relationship dimensions nor retailer-supplier cooperation have any influence on retailer’s DMU or supplier’s DMU. The results also indicate that differences and similarities exist across retailers and suppliers with respect to the effects of several relationship dimensions on cooperation and uncertainty. 2 The holistic empirical model developed for this research contributes further to understanding the links, which have been lacking in the extant channel relationship literature and supply chain management literature, between buyer-supplier relationships, DMU, and supply chain performance. The findings that a retailer/supplier’s DMU can erode the performance of a supply chain in various aspects highlight the need for improvement in some areas of supply chain efficiency and effectiveness, through cooperation-enhancing actions between the retailer and the supplier. From a managerial perspective, the performance improvement in the supply chain, in turn, will motivate more reciprocal commitment and efforts from the retailer and the supplier to maintain their working relationship. As such, mutual trust and enriched guanxi, dependence and non-coercive power help both the retailer and the supplier to have less uncertainty in their purchase/supply decision-making process. It creates a win-win position for both parties in the supply chain.

Recent studies in water management policy point to insufficient recognition of water as a scarce commodity and the failure of pricing policies to account for the full economic costs of its production and supply. These costs include opportunity costs related to alternative uses of water; user costs associated with managing a scarce resource; and costs of externalities such as ground water depletion, pollution of waterways, and greenhouse gas emissions. Existing cost recovery based pricing policies may lead to inefficiencies such as excess consumption, under-investment in water infrastructure, and unnecessary subsidisation. Water scarcity can be managed in several ways. We can increase supply by investment in additional harvesting capabilities or new technologies such as desalination; we can constrain consumption so that existing supplies last longer; or we can use water in more efficient ways. As a short term measure, most countries adopt water restrictions when supplies are at critical levels. In the future, as urban population growth continues, harvesting of storm water and reuse of grey water may become part of a sustainable water management strategy. Water trading can be used to move water to where the marginal benefits are highest. Considerable water savings are possible through the use of more efficient industrial and domestic appliances. There is evidence in some countries that higher water tariffs have reduced consumption and promoted awareness of conservation. If we accept that water is an economic good, then we need to understand the costs related to its production, the patterns of its use, and the benefits received by different users. This thesis is an examination of theoretical and applied aspects of urban water pricing based on analysis of cost, demand, and welfare. We present theoretical models of cost that include economies of scale as a parameter, and a model of water demand by households with heterogeneous preferences. We determine marginal cost at the efficient level of output based on a partial equilibrium of supply and demand. We also show that when water is produced with increasing returns to scale, the efficient price will be insufficient to recover all costs, and therefore a form of second best pricing is required. We contrast conventional notions about water suppliers being cost minimisers with an alternative frontier model of cost efficiency. Two case studies examine the provision of water services under different forms of ownership. The first case study examines the provision of water to domestic households in the state of Victoria, Australia. The second case study examines the supply of water to the residents of Manila, one of the world’s largest cities that privatised its water service in 1997 under a form of concession agreement. A third case study derives an efficient cost frontier for a sample of water utilities from Asia and Australia and proposes a form of best practice pricing. The thesis concludes with a summary of the main results and policy conclusions, and ideas for future research. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1289196 / Thesis (PhD) -- School of Economics, 2007

<p> </p><p>Saab Microwave Systems (SMW) is a business unit within Saab AB that manufactures and develops different types of radar- and sensor systems for naval, airborne and ground based forces as well as within the market for civil security. In addition to the manufacturing of radar and sensor systems they also provide different types of service concepts. The business unit has 50 years of experience within the area of developing radar systems and is considered to be one of the market leaders. When applying an assemble-to-order production strategy with products at this level of cost price the product lead-time is vital and becomes an important part of the strategy within marketing and sales.</p><p> </p><p>Within SMW there is a new department called Supply Management (SM) that provides the supply of incoming and outgoing material. Within SM there are four sub-departments working with activities such as planning, purchasing, receiving inspection, storage and distribution. Today, the supply process is relatively inefficient and there are delays in the flow due to suddenly arising problems. These delays generate big problems since SMW applies a just-in-time purchasing strategy. Based upon this problem the major purpose of this thesis work is to perform an analysis of the material flow in order to identify problems and contribute to a more efficient supply process.</p><p> </p><p>When the problems were identified the authors in consultation with the management choose to give priority to one problem in order to have a more finite focus regarding the analysis. The most serious problem that are given priority to is the receiving inspection since there is a lack of proper measurements, the planning is inadequate, the level of inspection is to high as well as uncontrolled, the inspections are based upon subjective appraisals and there is a lack of storage space. Within this problem there will be an extra focus upon the level of inspection even though the other problems will be given thought as well. When this problem was chosen as the main area of focus the authors took the level of importance and usefulness for the company into consideration, what came up during the analysis of the material flow as well as what the authors considered to be the best area of focus given existing conditions.</p><p> </p><p>The suggested improvements presented by the authors mainly consist of two areas regarding the level of inspection. The first suggestion consists of a filtering model that through a set of parameters are able to decide whether a specific article should be going through a reduced level of inspection or not. The second suggestion consists of a model that the company could use when they are phasing in new suppliers or improving existing ones. The purpose of this model is to create a close collaboration between important suppliers and SMW in order to reach a higher level of quality on the incoming material. The reason to why this model is created is due to the fact that the company has a very high level of inspection regarding incoming material today since the quality in many cases is faulty. By using this model the authors' ambition is to reduce the risk of defectives reaching SMW by supplier collaboration and this way oppose defectives earlier in the material flow. In addition to these suggested improvements the authors also suggest some thoughts and ideas regarding what is needed to be taken into consideration in order to reach a better planning and how the work efficiency within the receiving inspection department can be improved.</p> / <p> </p><p>Saab Microwave Systems (SMW) är en affärsenhet inom Saab AB och de tillverkar och utvecklar idag olika typer av radarsystem för luftfart, markbaserade enheter samt inom det marina. Företaget tillverkar och utvecklar även radarsystem inom marknaden för civil säkerhet. Vid sidan av tillverkningen av radar- och sensorsystem erbjuder företaget även intilliggande servicekoncept och eftermarknadsservice. Enheten har 50 års gedigen erfarenhet inom området radarutveckling och är ett ledande företag på marknaden. Med en kundorderstyrd produktion av produkter i denna höga prisklass blir ledtid en viktig del av marknadsföring och försäljningsargumentation vilket innebär att materialförsörjningen är vital för framgång.</p><p> </p><p>Inom SMW finns idag en nybildad enhet, Supply Management (SM), som ombesörjer materialförsörjningen av gods till och från SMW. Inom denna enhet finns fyra undergrupperingar; planering, operativt inköp, ankomstkontroll och förråd samt godsmottagning och spedition. I dagsläget fungerar inte materialförsörjningen som önskat utan det uppstår ofta brister och förseningar i flödet, något som skapar stora problem då SMW i så hög utsträckning som möjligt försöker tillämpa inköpsstrategin just-in-time. Med hänsyn till detta är examensarbetets främsta uppgift att göra en flödesanalys i syfte att identifiera brister och effektivisera materialförsörjningen.</p><p> </p><p>Efter att ha presenterat en bristidentifiering, baserad på en flödeskartläggning, har författarna i samråd med ledningsgruppen för enheten Supply Management valt att prioritera en brist för att ha ett konkret fokusområde för arbetet med analys och förbättringsförslag. Den allvarligaste bristen som prioriteras för vidare arbete är en ineffektiv ankomstkontroll där det saknas vettiga nyckeltal och verksamhetsmätning, där planering och resurssättning sker utifrån osäkra data, kontrollomfattningen är hög och okontrollerad, kontrollerna baseras på subjektiva bedömningar samtidigt som det råder utrymmesbrist i lager och förråd.  Inom denna brist läggs extra fokus på kontrollomfattningen även om övriga problemområden också tas i beaktning i ett vidare arbete. När fokusområde valdes togs hänsyn till vad som framkom i bristidentifieringen, vad som var viktigast och mest kritiskt för SMW samt vad författarna ansåg sig kunna prestera utifrån gällande förutsättningar.</p><p> </p><p>Författarnas förbättringsförslag består främst av två huvudområden kopplade till kontrollomfattningen. För det första presenteras en filtreringsmodell som genom ett antal parametrar sorterar artiklar efter huruvida de bedöms kunna genomgå en lättare (billigare och mindre resurskrävande) kontroll eller inte. Det andra förslaget är en modell för hur företaget kan arbeta när de fasar in nya och/eller utvecklar utvalda leverantörer med hög inverkan i syfte att skapa ett nära samarbete där högre kvalitet kan uppnås. Syftet med framtagning av modellen samt dess utformning grundar sig i att kontrollomfattningen som utförs på SMW är kopplad till inkommande kvalitet. Utifrån detta perspektiv vill författarna genom denna modell reducera riskerna för dålig inkommande kvalitet tidigare i materialflödet genom ett organiserat samarbete. I tillägg till dessa förslag presenteras även idéer och tankar på vad som bör tas i beaktning för att kunna uppnå en bättre och mer sanningsenlig planering samt hur arbetseffektiviteten kan höjas genom att tillsätta en administrativ- och teknisk roll på ankomstkontrollen.</p>
