All professions have practitioners who are considered to be experts. Less is known, however, about how these people achieve this level of excellence and about the factors that influence the attainment of expert practice in any profession. Using acknowledged expert nurses as a focus, this dissertation explored and evaluated the following factors that the literature suggested affect the progression from novice to expert: information-processing, problem-solving, and intuition abilities: mentors and mentoring: motivation and education: experience: and institutional incentives. An additional factor -- intrinsic motivation, which was not identified a priori, emerged in the course of the research. The conceptual framework used for this study was the novice-to-expert progression developed by Dreyfus & Dreyfus and applied to nursing by Benner. Benner's framework comprises novice, advanced beginner, competent, proficient, and expert. A qualitative case study method was used employing in interviews of ten clinical nurse specialists (CNSs). Data analysis was conducted following standard procedures for qualitative descriptive analysis. The study demonstrated that all of the CNSs progressed through each of Benner's stages during their careers. The following factors were identified as influential in their achieving expertise: information-processing and problem solving; mentors and mentoring; motivation and education; experience; intrinsic motivation. Institutional incentives and intuition played very weak roles and were not considered influential in achieving expertise, although the CNSs stated that the latter was an important element of their practice. This study has several implications for practice and research. With respect to practice, there is a clear need for mentoring programs, graduate education, internship programs, a stronger emphasis on experience, and policies to assure patient assignments are correlated with the level of the practitioner. Further research is suggested on all factors identified, especially the clinical ladder. The study contributes to adult education theory by clarifying the factors which foster the attainment of expertness, and to practice by suggesting areas in which interventions and innovation might be effective. / Ph.

This dissertation concerns the ways engineers and safety specialists acting as part-time volunteers cooperate in the setting of voluntary industrywide product safety standards in the farm equipment industry. These cooperative efforts are based, I contend, on collective investment criteria shared by both companies and individual participants. companies expect long-term benefits stemming not only from their early access to information about the proposed changes in product design, but also from the extent they can influence the outcome in ways that reduce their costs and accommodate their product design and manufacture requirements. Individual participants expect to benefit professionally from the knowledge exchanges taking place in the deliberations. I illustrate my argument through a case study in the development of a family of safety standards for agricultural tractors. The study shows that, in setting these standards, participants sought and achieved ways of making their proposed changes in product design more compatible with a changing legal order. The study also shows, however, that collective action may bring some unintended consequences. For instance, given the stiff demands of this order, participant companies' collective efforts to build such compatibility may and did ultimately compromise the voluntary character of both their participation in the deliberations and the implementation of the proposed changes in product design / Ph.

This dissertation presents the case for a normative vision of the relationship between technical experts and other non-expert members of a democratic citizenry. This vision is grounded in two key insights that have emerged from the field of science and technology studies. First, is the "third wave" science studies movement that identifies problems of expertise as the "pressing intellectual problem of the age." Characterized by the problems of legitimacy and extension, Collins and Evans build the case for the extension of the category of expertise to include those who have the relevant experience but lack relevant accreditation. Alongside this extension of the category of expertise is the extension of those who participate in the framing of techno-scientific issues. This dissertation builds a case for the inclusion of all democratic citizens in the problem framing process. What we are left with from the current "third wave" literature is a multi-tiered prescription for the role of non-experts in public decision-making about science and technology. On the ground floor, when the issue is being framed there is a need to include non-expert stakeholders (in theory, any concerned democratic citizen). Once a framing of the problem has been constructed, there is a need to recognize a larger category of people who count as "expert." Together, these constitute the two most powerful prescriptive elements of expertise developed in the recent science studies literature. The dissertation then explores claims that it is specifically "deliberative" theories of democracy that are best suited to make sense out of this democratization of expertise. After presenting a typology of deliberative theories of democracy that clears up a serious problem of equivocation found in appeals to deliberative democracy in current STS literature, this dissertation argues that only a specific set of deliberative theories of democracy, "discursive" deliberative theories of democracy, are capable of fulfilling the role theories of deliberative democracy are assigned in current STS literature. The dissertation then goes on to suggest how these new insights into the democratization of expertise might affect future instantiations of technology assessment mechanisms (such as the office of Technology Assessment) in the U.S. / Ph.

The goal of this research project is to tell the story of acquisition expertise development within the DOD using the evolution of the Defense Acquisition University as its backdrop. It is a story about the persistent frame that claims expertise leads to acquisition success. It is about 40 plus years of competing perspectives of how best to acquire that expertise and their shaping effects. It is about technology choices amidst cultural and political conflict. It is about how budget, users, infrastructure, existing and emerging technologies, identity and geography all interrelate as elements within the technology of expertise development. Finally, it is about how at various times in the evolution of the Defense Acquisition University the technologies of tacit knowledge transfer have been elevated or diminished. / Ph. D.

More and more in recent years, activities that people once did in the real world they now do in virtual space. In particular, online communities have become popular and efficient media for people all over the world to seek and share knowledge in domains that interest them. Such communities are called online knowledge communities (OKCs). Large-scale OKCs may comprise thousands of community members and archive many  more online messages. As a result, problems such as how to identify and manage the knowledge collected and how to understand people\'s knowledge-sharing behaviors have become major challenges for leveraging online knowledge to sustain community growth. In this dissertation I examine three important factors of managing knowledge in OKCs. First, I focus on how to build successful profiles for community members that describe their domain expertise. These expertise profiles are potentially important for directing questions to the right people and, thus, can improve the community\'s overall efficiency and efficacy. To address this issue, I present a comparative study of models of expertise profiling in online communities and identify the model combination that delivers the best results. Next, I investigate how to automatically assess the information helpfulness of user postings. Due to the voluntary nature of online participation, there is no guarantee that all user-generated content (UGC) will be helpful. It is also difficult, given the sheer amount of online postings, for knowledge seekers to find information quickly that satisfies their informational needs. Therefore, I propose a theory-driven text classification framework based on the knowledge adoption model (KAM) for predicting the helpfulness of UGC in OKCs. I test the effectiveness of this framework at both the thread level and the post level of online messages. Any given OKC generally has a huge number of individuals participating in online discussions, but exactly what, where, when and how they seek and share knowledge are still not fully understood or documented. In the last part of the dissertation, I describe a multi-level study of the knowledge-sharing behaviors of users in OKCs. Both exploratory data analysis and network analysis are applied to thread, forum and community levels of online data. I present a number of interesting findings on social dynamics in knowledge sharing and diffusion. These findings potentially have important implications for both the theory and practice of online community knowledge management. / Ph. D.

During the 1980s, an acute and deadly epidemic appeared in the United States. AIDS, a disease that initially affected mainly gay men, required a rapid and effective treatment. Due to tough regulations form government agencies and the stigma surrounding the disease, it would take a long time for a treatment to be developed. To break the silence, demand action and push for changes to combat the AIDS epidemic, the activist group ACT UP (AIDS Coalition to Unleash Power) was formed. A network formed around their actions that created an environment capable of developing new treatment methods. Using interviews, articles, and reports, this analysis will draw on Actor-Network Theory (ANT) to examine how ACT UP mobilizes lay expertise and navigates conflicts within its network to influence research processes and AIDS treatment. This analysis highlights the mobilization of lay expertise and shows how the constructive management of conflicts within networks can play a crucial role in challenging established research structures, influencing decision-making processes, and ultimately shaping the response to public health crises like the AIDS epidemic.

Various prior research studies have investigated the positive and negative effects of an audience on task performance, yet very little research has been conducted specifically on dancers. The focus of this study will be on the interaction between Goal Orientation and Level of Expertise in relation to social facilitation and task performance in ballet dancers. Participants were assessed based on performance with and without an audience at varying levels of expertise. The theory of social facilitation was examined in relation to several subject variables mentioned in background research. The results of this study suggest a trend supporting the hypothesis that a person's reaction to an audience is at least partly dependent on both Goal Orientation and Level of Expertise as explained by drive theory. This study gives dancers valuable insight on personal performance.

No / The purpose of this paper is to explore the determinants of relationship quality (hereafter referred to as RQ) and its impact on customer loyalty within an emerging retail banking market through a dual-lens theory. The research informants were recruited from a city in South-eastern Nigeria. A quantitative data obtained through bank-intercept method and online survey from 332 customers of retail banking services formed the final database. The proposed model and by implication the research hypotheses were tested using partial least squares structural equation modelling procedure. he results show that customer orientation, expertise and information sharing are stimulus factors that directly influence the constructs of RQ (i.e. trust and satisfaction and indirectly influence customer loyalty through the constructs of RQ. The paper also demonstrates that the stimulus factors are direct predictors of consumers’ response. The proposed model explained 49 per cent of the total variance in customer loyalty. Customer orientation, expertise and information sharing are stimulus factors that improve RQ and customer loyalty. However, the explanatory power of the proposed model is modest. Future research should therefore integrate other determinants of RQ. The paper contributes to the growing body of stimulus-organism-response (S-O-R) literature within the retail environment by exploring unique stimulus and organism variables from an emerging retail banking market perspective. Additionally, by showing that the stimulus factors are direct predictors of consumers’ response, the paper challenged the existing tenets of the S-O-R framework and deepened the current understanding of the model. The paper also contributes to the social exchange theory by demonstrating how the components of RQ mediate the antecedents and consequences of the construct.

Yes / The importance of involving members of the public in the development, implementation and dissemination of research is increasingly recognised. There have been calls to share examples of how this can be done, and this paper responds by reporting how professional and lay researchers collaborated on a research study about falls prevention among older patients in English acute hospitals. It focuses on how they worked together in ways that valued all contributions, as envisaged in the UK standards for public involvement for better health and social care research. The paper is itself an example of working together, having been written by a team of lay and professional researchers. It draws on empirical evidence from evaluations they carried out about the extent to which the study took patient and public perspectives into account, as well as reflective statements they produced as co-authors, which, in turn, contributed to the end-of-project evaluation. Lay contributors' deep involvement in the research had a positive effect on the project and the individuals involved, but there were also difficulties. Positive impacts included lay contributors focusing the project on areas that matter most to patients and their families, improving the quality and relevance of outcomes by contributing to data analysis, and feeling they were 'honouring' their personal experience of the subject of study. Negative impacts included the potential for lay people to feel overwhelmed by the challenges involved in achieving the societal or organisational changes necessary to address research issues, which can cause them to question their rationale for public involvement. The paper concludes with practical recommendations for working together effectively in research. These cover the need to discuss the potential emotional impacts of such work with lay candidates during recruitment and induction and to support lay people with these impacts throughout projects; finding ways to address power imbalances and practical challenges; and tips on facilitating processes within lay groups, especially relational processes like the development of mutual trust. / Funded by the National Institute for Health Research (NIHR) Health and Social Care Delivery Research (HSDR) Programme (Project Number NIHR129488).

Cette thèse a pour ambition d’analyser un aspect encore mal connu de la transition postsoviétique des États baltes : l’évolution d’une politique étrangère placée entre récepteurs et donneurs d’assistance étrangère au prisme de l’action de parrainage transnational. Nous observons, dans une approche constructiviste, la transformation et la redéfinition des concepts d’identité politique et de solidarité face à l’Autre et le regard que ce dernier porte sur Soi. Malgré l’évolution de cette identité, des continuités persistent : Le rapprochement opéré avec l’Europe de l’Est depuis une dizaine d’années est non seulement l’une de priorités politiques des États baltes, il s’inscrit parallèlement dans leur désir d’aspirer à devenir de « vrais » Européens et d’être perçus comme tels. Cette thèse met en lumière deux dimensions de cette solidarité : la solidarité politique d’une part, la mise en pratique de celle-ci par l’assistance technique, d’autre part. Il s’agit d’abord de comprendre les différentes logiques dans lesquelles s’inscrit la solidarité balte et d’identifier ses acteurs et réseaux. Dans une démarche interdisciplinaire qui croise notamment les mécanismes de Policy Transfer Studies et l’approche historique et comparative, cette thèse s’attache ensuite à mieux définir les processus et les modes de mise en œuvre, ainsi que le rôle des acteurs « émetteurs » (les experts) et leur interaction avec leur partenaires. Elle arrive à la conclusion que les Baltes diffusent et partagent avec les pays du voisinage oriental de l’UE principalement l’expérience qu’ils ont acquise, s’inspirant logiquement de l’action nordique de parrainage dont ils ont bénéficié au cours des années 1990. / This doctoral thesis aims to analyse one of the less known aspects of Baltic transition: the evolution of their foreign policy between receptors and donors of foreign assistance through transnational patronage (1985-2013). In line with the constructivist school of thought, we observe how the concept of political identity and solidarity changes, redefines itself towards the Other and the perception that the latter has on the Self. Notwithstanding the changes in this identity, some continuities seem to persist: The rapprochment with Eastern Europe over the past ten years could viewed as one of the priorities of the Baltic States but it also stems from the desire of these States to become and to be considered as “fully” European. This thesis sheds some light over the two dimensions of this solidarity: the political solidarity and support on the one hand, and its implementation through technical assistance to reforms and trainings of Georgian, Ukrainian and Moldovan elites, on the other hand. In order to better observe how the solidarity is expressed, this study attempts to understand the different logics of the Baltics solidarity, to identify different actors and networks involved. In an interdisciplinary approach intersecting the mechanisms of PTS and the historical and comparative approach, this study takes then focuses on the processes and methods of the implementation, the role of the actors “donors” and their interaction with their partners. It concludes that Baltic States diffuse and share with the Eastern neighbours of EU mostly their own experience inspired from the Nordic States’ patronage action towards the Baltics during the 1990.
