There must be a human factor to explain the lack of logic in luxury consumption. This irrational behavior is subject to explanation in this thesis, using values to map a framework where hopefully, conclusions can be drawn regarding how values drive people to consume luxury clothing. An individual’s luxury value perception and the motives for luxury clothing consumption are not simply tied to a set of social perspectives of displaying status, success, distinction and the human desire to impress other people, but also depend on the nature of the financial, functional and individual utilities of the certain luxury brand (Wiedmann et al., 2007). The values are divided into different dimensions with “sub-dimensions”: financial “price”, functional “usability, quality and uniqueness”, individual “self-identity, hedonic and materialistic” and social “conspicuousness, prestige and contextual”. The different values presented and the conceptualized framework might provide some insight into the matter of why we consume luxury goods and the underlying reasons behind consumer behavior, what values motivate us to consume and explain the paradox of luxury consumption.

The entrepreneurship dynamism of a country is the center of Schumpeter’s creativedestruction process and virtuous circle, in which new and innovative companies enteringthe market drive the obsolete and less productive ones out of the market. As aconsequence of this process, the market is improved and it incentivizes the creation ofinnovative solutions to solve problems. The study focuses on the pivotal function of theentries in this process. To better understand the creation of new ventures process the study investigates how thecontextual factors impact the entrepreneur’s decision of starting a new business, focusingon two business environments: Sweden and Brazil. Through interviews with Swedish andBrazilian entrepreneurs we analyze how entrepreneurs perceive the contextual factors andhow it impacted their new venture creation process. Through the literature we find that the business environment is composed by seven majorfactors that, with an extended framework based on literature review, we consider as:economic wealth, government policies and procedures, legal & administrative, society’sculture; network and knowledge; financial assistance; and non-financial assistance. Analyzing the empirical material about the business environments we find that Swedishand Brazilian entrepreneurs feel the influence of the different contextual factors inbusiness creation but do not always understand their causes. Our findings show that theseven contextual factors do not have the same level of influence in Sweden and Braziland often depend on the environment. However, for entrepreneurs in both two contextualfactors have a pivotal impact: network and financial assistance. This study contributes to the theory by providing a more detailed extended framework tostudy the influence of contextual factors on the process of starting a new business.Furthermore, this research also contributes by providing empirical evidence of Swedishand Brazilian entrepreneurs’ perceptions of their business environment and the influenceof the contextual factors.

The growing need for designing and implementing reliable voice-based human-machine interfaces has inspired intensive research work in the field of voice-enabled systems, and greater robustness and reliability are being sought for those systems. Speech recognition has become ubiquitous. Automated call centers, smart phones, dictation and transcription software are among the many systems currently being designed and involving speech recognition. The need for highly accurate and optimized recognizers has never been more crucial. The research community is very actively involved in developing powerful techniques to combine the existing feature extraction methods for a better and more reliable information capture from the analog signal, as well as enhancing the language and acoustic modeling procedures to better adapt for unseen or distorted speech signal patterns. Most researchers agree that one of the most promising approaches for the problem of reducing the Word Error Rate (WER) in large vocabulary speech transcription, is to combine two or more speech recognizers and then generate a new output, in the expectation that it provides a lower error rate. The research work proposed here aims at enhancing and boosting even further the performance of the well-known Recognizer Output Voting Error Reduction (ROVER) combination technique. This is done through its integration with an error filtering approach. The proposed system is referred to as cROVER, for context-augmented ROVER. The principal idea is to flag erroneous words following the combination of the word transition networks through a scanning process at each slot of the resulting network. This step aims at eliminating some transcription errors and thus facilitating the voting process within ROVER. The error detection technique consists of spotting semantic outliers in a given decoder's transcription output. Due to the fact that most error detection techniques suffer from a high false positive rate, we propose to combine the error filtering techniques to compensate for the poor performance of each of the individual error classifiers. Experimental results, have shown that the proposed cROVER approach is able to reduce the relative WER by almost 10% through adequate combination of speech decoders. The approaches proposed here are generic enough to be used by any number of speech decoders and with any type of error filtering technique. A novel voting mechanism has also been proposed. The new confidence-based voting scheme has been inspired from the cROVER approach. The main idea consists of using the confidence scores collected from the contextual analysis, during the scoring of each word in the transition network. The new voting scheme outperformed ROVER's original voting, by up to 16% in terms of relative WER reduction.

Measuring crime is one of criminology’s most central tasks. Self-report studies constitute one means of doing so. By asking people, primarily youths, about their experience of involvement in criminal acts, self-report studies are intended to provide knowledge on the extent and structure of crime and on crime trends over time, while also providing opportunities to study the causes of crime. The dissertation’s objective is to examine the use of self-reported crime as a research method. It problematises the use of self-report studies as an instrument for measuring both the extent and structure of youth crime, and also trends in youth crime over time. Problematising the method in this way both illustrates the significance of methodology and measurement instruments for the production/construction of criminological data and makes possible a more nuanced and aware approach to the use of such data. The dissertation comprises a discussion of the basic assumptions of the self-report method viewed from the perspective of theory of science, a review of Swedish self-report studies and a detailed study of the Swedish School Survey on Crime, Sweden’s nationally representative self-report study of youth in year nine (aged 15). The dissertation’s most important conclusions are that researchers, when designing a self-report study, should consider both how crime is viewed and what the study is intended to examine. It is also important, when using self-report data, to consider what the data represent. This is of significance in relation to both how questions might best be formulated and to what extent the mechanisms that affect the results will involve problems for the quality of the measures obtained.

This thesis presents the results of three studies that extend understanding of ethical decision making in negotiation. First, by comparing how Chinese and Australian negotiators think about contextual variables in an interpretive study, an extended model of ethical decision making in negotiation is offered. This study suggested differences in how codes of ethics and perception of the other party were understood as well as a shared understanding of the influence of the legal environment across the two cultures. Importance of organisational goals and personal and business reputation also emerged as important variables in negotiators' ethical decision making. The next study began testing the extended model with an investigation of the interaction between culture and closeness of the relationship with the other party using the SINS scale (Robinson, Lewicki, & Donahue, 2000). It was found that Chinese negotiators generally rated ethically ambiguous negotiation tactics as more appropriate than Australians, and that Chinese differentiated more in their ratings of appropriateness according to the social context. In the test for metric equivalence of the SINS scale, this study found that the existing approach of inductively deriving types of ethically ambiguous negotiation tactics based on ratings of perceived appropriateness is flawed since patterns of ratings are likely to vary across groups of negotiators. In light of this, a new typology of ethically ambiguous negotiation tactics is offered based on an a priori identification of conceptually distinct types of tactics. This new inventory of items represents the first step in the process of producing a cross-culturally generalisable scale of ethically ambiguous negotiation tactics.

The purpose of this study was to obtain an in-depth understanding of the perceptions of overseas-qualified nurses from non-English speaking backgrounds (NESB) in relation to their educational and socialisation experience whilst enrolled in a Competency Based Assessment Program (CBAP). The study was conducted using a modified grounded theory approach. There were a total of seventeen participants; fourteen NESB nurses, and three teachers who were directly involved with their education in the CBAP. The NESB nurses who participated fell into three main groups in terms of their previous professional experience. These were: � Specialist � Experienced generalist � Inexperienced generalist However, the level of skill and experience that the nurses brought to the educational and practice encounter made no difference to their experience of prejudice and lack of support, particularly in the clinical environment. The education and clinical experience they received challenged feelings of competency as much as they expanded feelings of competency. The NESB nurses� experiences of diversity also challenged their feelings of competence. In addition, the level of previous experience did not reduce the concern expressed by NESB nurses regarding the possibility of finding appropriate employment following registration. The implications of this for the profession and the health care system are that even the most experienced specialist and generalist nurses are not having their level of skill appropriately recognised and utilised in a timely way despite the current shortage of generalist and specialist nurses in Victoria. The outcome of the study led to the development of a model that has the potential to lead to a culture change in the clinical environment with a view to improving educational opportunities and experiences for NESB nurses who are enrolled in CBAP. In addition, the model has the potential to be useful in terms of providing local nurses with an opportunity to express their own thoughts and ideas in relation to the education of NESB nurses in the clinical environment. The model is based upon the theoretical perspectives of �productive diversity� and �clinical governance and organisational learning�.

Genetic medicine is an emerging area of healthcare which constantly raises novel ethical challenges in the clinical realm due to its capacity to reveal information that has deeply personal meaning. Genetic tests can reveal more than is strictly essential for immediate medical care because they can diagnose conditions that cannot be cured, treated or effectively managed. The diagnosis of a genetic condition in one individual can have repercussions throughout an extended family, and genetic knowledge has created innovative, technologically driven, reproductive options. For clients of genetic counselling, moral choice does not readily result from uncluttered logic or easy personal preference, nor does it involve the application of sterile principles and laws, but is a much richer process involving personal history and culture, as well as reflection upon personal values, current resources and projected life goals. For these reasons, I question the validity of the exclusive use of a narrow version of Principlism, as it is commonly operationalised, for the medical sub-specialty of clinical genetics. Its heavy emphasis on individual autonomy, which has become synonymous with clinical medicine, does not take into account the fact that most genetic tests have little or no immediate clinical utility, or that genetic medicine is primarily about the way in which genetic conditions pass through families, and management of recurrence risks by choice of reproductive options. Therefore, the aim of this dissertation is to develop and explore a broader contextual moral framework, which is better suited to deliberation about complex ethical dilemmas in clinical genetics, than the current dominant approach which tends to follow a restrictive and non-inclusive application of Principlism. To achieve this aim, I have started with a review of relevant history and socio-political forces that have shaped the current status of the genetic medicine, and examined the evolution of current attitudes that underpin recognition, analysis and management of the ethical challenges in genetic medicine. I have analysed the manner in which Principlism and other normative theories are employed by bioethicists and clinicians in response to ethical dilemmas, and presented an alternative approach which employs a broader contextual ethical framework. I have devised an approach which attends to the importance of both current social opinion, and the tradition of evidence-based medicine, with reference to selected traditions in philosophical analysis. vi In conclusion, I advocate attention to concrete circumstances, which includes recognition of historical development, which has shaped current medical and wider social values, beliefs, norms and attitudes political context, including critical analysis of relevant political motivations social context, particularly situational power structures, trust relationships and relational obligations personal values, resources and experiences of the stakeholder(s) the range of realistically available options for the stakeholder(s) the impact of economic limits, which might be institutional and / or personal And, to achieve this objective of building a ‘thick’ ethical discourse, I propose a series of questions, which can be readily utilised by genetic and non-genetic health professionals as well as other members of society to work towards resolutions that represent a balance of fairness, economic responsibility with scarce resources, and socially acceptability. This approach appropriately attends to the relational and communicative aspects of moral dilemmas in clinical genetics, and is likely to yield more meaningful (and less likely paternalistic) conclusions, which would be of greater value to our morally pluralist society.

Contextual information retrieval (CIR) is a critical technique for today’s search engines in terms of facilitating queries and returning relevant information. Despite its importance, little progress has been made in its application, due to the difficulty of capturing and representing contextual information about users. This thesis details the development and evaluation of the contextual SERL search, designed to tackle some of the challenges associated with CIR from the World Wide Web. The contextual SERL search utilises a rich contextual model that exploits implicit and explicit data to modify queries to more accurately reflect the user’s interests as well as to continually build the user’s contextual profile and a shared contextual knowledge base. These profiles are used to filter results from a standard search engine to improve the relevance of the pages displayed to the user. The contextual SERL search has been tested in an observational study that has captured both qualitative and quantitative data about the ability of the framework to improve the user’s web search experience. A total of 30 subjects, with different levels of search experience, participated in the observational study experiment. The results demonstrate that when the contextual profile and the shared contextual knowledge base are used, the contextual SERL search improves search effectiveness, efficiency and subjective satisfaction. The effectiveness improves as subjects have actually entered fewer queries to reach the target information in comparison to the contemporary search engine. In the case of a particularly complex search task, the efficiency improves as subjects have browsed fewer hits, visited fewer URLs, made fewer clicks and have taken less time to reach the target information when compared to the contemporary search engine. Finally, subjects have expressed a higher degree of satisfaction on the quality of contextual support when using the shared contextual knowledge base in comparison to using their contextual profile. These results suggest that integration of a user’s contextual factors and information seeking behaviours are very important for successful development of the CIR framework. It is believed that this framework and other similar projects will help provide the basis for the next generation of contextual information retrieval from the Web.

This research focused on the question, How do practitioners understand the transfer of competence (that is, what do they know and can do) accross different workplace contexts and how does it influence their practice? The research investigates the experiences and perceptions of 108 workers, who have changed jobs or whose jobs have changed, as to how they were able to adapt what they knew and could do at the time. The research is phenomological, using a methodology designed to collect and analyse data from the participants without decontextualising it. The methodology is customised and contextualised and uses activity theory, Engestrom's theory of expansive learning, grounded theory and discourse analysis to interrogate the research question. The collection of data occurred over a period of five years and was in two stages, with the second stage validating and building on the first stage. Minimally structured interviews and a questionnare were the main data collec tion tools used. Some descriptive statistics have been used but the research is qualitative in intent. The research draws on current theoretical positions of learning, transfer, experimental learning, workplace learning, activity theory, qualitative research and reflection on experience. The thesis has been written to foreground the voices of the participants and the insights their experience brings to the research. The research addresses a current gap in research work, carried out in Australia or overseas, which focuses on the transfer of competence across workplaces. The outcomes provide new perspectives on the ways in which practitioners understand transfer and integrate these interpretations into their generalisation without decontextualisation, and thus makes a contribution to our collective knowledge and understanding. The outcomes of the research are a metaphoric framework to guide the transfer of competence over different work contexts; a record of the application of new understandings of transfer as a sequence of consequential transitions (Beach 1999); generalisations derived from the embedding of contexts (Van Oers 1998); and an innovative research methodology. In addition, the participants have provided their perspectives on the preperation of, and on-going support for, people entering or crossing workplace contexts, and the consequential, necessary changes to institutional learning.
