As síndromes coronarianas agudas são responsáveis por uma elevada taxa de mortalidade no Brasil e no Mundo. As falhas diagnósticas, principalmente quando o paciente é atendido em serviços de pronto socorro, por clínicos gerais, certamente contribuem para esse quadro, embora amenizadas pelos sistemas cardiológicos de tele-medicina. Entretanto, muitos serviços de emergência não têm acesso a esses sistemas e, além disso, possuem uma limitada capacidade diagnóstica em casos de coronariopatia aguda. Neste trabalho foi desenvolvido um sistema de inteligência artificial baseado na lógica \"fuzzy\", capaz de auxiliar um médico generalista no diagnóstico desses casos, sem fazer uso de tele-medicina, nem de exames laboratoriais. O sistema utiliza um eletrocardiógrafo interpretativo para suprir as deficiências do médico na análise do eletrocardiograma. Usando a história clínica, o exame físico e o laudo eletrocardiográfico automático, dados são inseridos em uma planilha Excel que fornece uma sugestão de diagnóstico e de respectiva conduta terapêutica. O sistema demonstrou um bom desempenho, sendo, assim, uma solução viável e de baixo custo para o diagnóstico precoce de síndromes coronarianas agudas em unidades primárias de pronto socorro. / Acute coronary syndromes are responsible for a high mortality rate in Brazil and worldwide. Diagnostic failures, especially when the patient is treated in emergency services by general practitioners, certainly contribute to this condition, although tele-medicine cardiology systems are possibly responsible for the reduction of that mortality rate. However, many services do not have access to these systems and also have a limited diagnostic capacity for diagnosing cases of acute coronary disease. We have developed an artificial intelligence system using elements of \"fuzzy\" logic, capable of assisting a general practitioner in the diagnostic of these cases, without making use of tele-medicine or laboratory tests. The system uses an interpretive electrocardiograph that can overcome the general practitioners\' deficiencies in the analysis of the electrocardiogram. The physician, starting from the important elements of the clinical history, the physical examination and the electrocardiogram automatic report, enters data into an Excel program that will provide a suggestion of diagnostic and therapeutic management. The system is low cost and has shown great performance, so it is a viable solution to the problem of early diagnostic of acute coronary syndromes in primary emergency units.

Correctional officers work in a coercive environment and as such they are confronted with various challenges on a daily basis. Research found that the unique stressors that correctional officers experience result in stress which can negatively impact their physical and psychological health as well as their family life. However, limited research has been conducted to identify the stressors that are relevant to the South African correctional officer. Therefore, the aim of this study was to investigate South African correctional officers’ lived experiences of their work and work environment and the Employee Assistance Programme and the meaning they attached to them. Purposive and snowball sampling techniques were utilised to select the 20 participants from the two correctional centres of the Department of Correctional Services in Worcester, Western Cape. The sample consisted of 11 male and 9 female correctional officers between the ages of 26 and 56 years with a mean age of 43.4. A qualitative approach was utilised to obtain in-depth insights into the lived experiences and attributed meanings of participants. Individual interviews were conducted with the participants by utilising a semi-structured interview guide. A demographic questionnaire was completed by each participant after the interview. The interviews were audio-recorded with the written permission of each participant and transcribed for analysis. Through the use of Interpretive Phenomenological Analysis (IPA) 7 themes were identified namely: (a) confronting various challenges on a daily basis (b) various dimensions of correctional officers life affected (c) neglect of correctional officers’ well-being (d) coping mechanisms (e) barriers preventing corrections officers from utilising the EAP (f) a recognition of the positive value of the EAP (g) personal meaning derived from work. In addition, the themes consist of various subthemes. The findings of the study suggest that correctional officers are confronted with various challenges on a daily basis, which include lack of input into decision making, lack of support from management, lack of trust in management, pressure caused by staff shortages, lack of resources, inadequate training opportunities and a lack of promotion system. Furthermore, participants revealed that their work and work environment had a negative impact on their physical and psychological health as well as their family life. In addition, participants reported that aspects of their well-being are neglected which include a lack of interest from management in their problems, a lack of recognition and motivation from management as well as a lack of team-building opportunities. Various coping mechanisms were utilised by the participants which seems to act as a buffer against the negative effects of their stressful work and work environment. These coping mechanisms include conflict resolution and communication skills, religion, sport, positive thinking, resilience as well as family and co-worker support. A variety of barriers that prevent participants from using the EAP service that are offered at work were identified. These barriers indicated by the participants included a lack of trust in the EAP, the stigma attached to using the EAP, difficulty relating with the EAP practitioner, a negative perception of the EAP, and insufficient marketing of the EAP. Despite the barriers, participants recognised the overall positive value of the EAP service in the Department of Correctional Service. Participants appear to find meaning in their work. Some participants expressed the satisfaction that they experienced from their job while others expressed the sense of reward that they experience from their job. Recommendations for further research include the evaluation of the EAP programme to determine its effectiveness on a national level, more involvement from management in ground floor correctional officers, providing additional teambuilding oppertunities and reintroducing Wellness Days. A limitation of the study is that only a small sample of correctional officers limited to two correctional facilities in Worcester, Western Cape, was used. Therefore, the findings of the study could not be generalised to the whole population of South African correctional officers. / Psychology

L'introduction des formats de distribution alimentaire modernes dans le paysage commercial des pays émergents suscite des interrogations sur l'impact que cela produit sur les comportements de consommation et de magasinage des acheteurs locaux. La persistance du commerce traditionnel, ancré dans la culture locale, couplée à l'implantation d'enseignes de distribution modernes, renvoyant à l'image « idéalisée » de l'Occident, exerce une tension sur les goûts et les habitudes de consommation autochtones. Cette recherche doctorale explore les significations culturelles données aux pratiques de consommation et de magasinage dans ces pays en s'appuyant sur une importante étude qualitative de type ethnographique réalisée au Maroc. Les résultats montrent que l'introduction des formats modernes de vente sur ce marché émergent qui porte des valeurs socio-culturelles différentes de celles des pays d'importation est à l'origine de l'apparition de comportements hybrides ou de pratiques d'adoption sélective à travers lesquels les consommateurs cherchent à articuler des codes et des dimensions symboliques contrastés en vue de donner sens à leur consommation. En outre, la dualité du système de distribution accentue la logique du jeu des classes en amplifiant les tendances au marquage social du statut via la mise en scène (au sens de Goffman) de la consommation et de l'appropriation des espaces de vente. Par ailleurs, si l'introduction des nouveaux formats de vente constitue une vraie menace pour le commerce traditionnel, elle favorise par la même occasion la réorganisation du secteur, la diversification de l'activité de ses acteurs et l'amélioration de leurs pratiques de gestion. / The introduction of modern food retail formats in the emerging countries' commercial landscape raises questions on the impact it causes on the local buyers' consumption and shopping behavior. Anchored in the local culture, the persistence of traditional business coupled with the implementation of modern retail chains that put forth an ‘idealistic' image of the Western societies causes tensions on consumers' native tastes and habits. This doctoral research explores the cultural meanings given by consumers to shopping and consumption practices in these countries based on a large ethnographic qualitative study performed in Morocco. Results show that the introduction of modern sales formats in emerging markets where socio-cultural values differ from those of the importing countries causes hybrid behaviors or selective adoption practices to emerge through which consumers try to articulate contrasted codes and symbolic dimensions in an effort to give meaning to their consumption. In addition, the dual distribution system accentuates the social class game amplifying trends in social status tagging through the staging of consumption (as per Goffman) and the appropriation of the retail spaces. Furthermore, if the introduction of new retail formats is a real threat to traditional retailers, it favors by the same token the reorganization of this sector, the diversification of the activities by its actors as well as the enhancement of their management practices.

Information and Communication Technology is used in the education field in Sweden toimprove learning quality. The aim of this research is to investigate the use of LearningManagement Systems in primary schools, in the specific context of the role of LearningManagement System (LMS) in learning and teaching processes from teachers‟perspectives. Furthermore, This Thesis aims to explore teachers‟ perceptions of how touse this learning management system which is used in primary Swedish schools.Six teachers from two different primary schools in small municipality in the south ofSweden participated in semi-structured interviews. The theoretical model of UnifiedTheory of Acceptance and Use of Technology (UTAUT) inspired this qualitativeresearch along with the other related past studies. This quantitative model was only usedto sensitize the research process, for collecting and analysing qualitative data in thisstudy.The different elements of the theory such as performance expectancy, effort expectancy,social influence and facilitating conditions along with studies helps in conducting studybasedon qualitative approach for analysing the interviews. The research results indicatethat teachers were content with the usage of this learning management system, but thereis a lack of knowledge regarding this system. The system is helpful in performanceevaluation, planning, communication and overall working for routine tasks. Theresponses of interviews showed that teachers are not trained for using the features ofLearning management system in the way that it is designed for. The findings showed thatteachers require the support from professionals to integrate the system into their routineplanning. Furthermore, they also emphasise on the need to make the system user-friendlywith easy navigation. The findings of this study were compared to previous studies, anda further comparison was carried out regarding how it relates to the determinants andmoderating factors such as peer influence, internal perceptions and motivations, timeconstraints, organisational structure and facilitating conditions. Hence, support andtraining are needed to enhance learning and teaching through this Learning managementsystem.

Despite a narrowing trend over the past forty years, the racial academic performance gap between non-Asian-American minority students and European-American students remains an overarching issue in K-12 schooling according to the Stanford Center for Education Policy Analysis (2017). Du Bois’s (1903) theory of double consciousness is implicated in the performance gap phenomenon. Though not explicitly connected, Steele and Aronson’s 1995 study revealed stereotype threat (STT) to be an empirical explanation of the negative impact of double consciousness. Steele et al.’s study revealed a psycho-social contributor to the racial academic performance gap, STT. STT is characterized by performance suppression caused by the fear of fulfilling a negative stereotype or the fear of being judged based on a negative stereotype attributed to one’s social identity group. The activation of this phenomenon is related to identity threatening cues, a systemic issue laden in the academic environment (Purdie-Vaughns, Steele, Davies, Ditlmann, & Crosby, 2008). To date, over 300 studies have been conducted on STT according to a meta-analysis conducted by Pennington, Heim, Levy, and Larkin (2016). Though certain experimental studies featuring mentoring as a vehicle for shifting stereotype narratives have yielded useful practices for STT reduction (Good et al., 2003), qualitative design, which is seldomly employed in the STT field, may produce an understanding of the phenomenon that is not possible through a deductive approach (Ezzy, 2002; van Kaam, 1966). The purpose of this phenomenological study was to explore African-American adolescent student perceptions of the impact that mentoring has on their schooling experiences while under STT conditions. The findings of this study demonstrated that African-American adolescents perceived mentoring to positively impact their schooling experiences and helped them to cope with STT activating cues in the environment. The participants discussed structural aspects of the relationships, personality attributes of the mentor, and specific mentor guidance. Participants also discussed a documented STT intervention that fell outside of the parameters of their mentoring relationships that positively impacted their schooling experiences and abilities to cope with STT cues – affirmations (Cohen, Garcia, Apfel, & Master, 2006; Walton et al., 2012). Recommendations for practice and future research are presented.

Each day the joint managers of Uluru-Kata Tjuta National Park receive packages of returned rocks and sand that have been removed from the landscape by visitors as a souvenir of the place. The returned objects are sent from people all over the world as the stories of this phenomenon travel well beyond the Park boundaries. Known within the Park as the ‘sorry rocks’, these returned objects and their accompanying letters of apology reflect the different ways in which people engage with the landscape and interpret their surrounds. In this research, the sorry rocks have been used as a medium for examining the complex relationships that exist between visitors, heritage management and interpretation particularly in cross-cultural settings that recognise Indigenous cultural heritage.

Doctor of Philosophy / The aim of the research presented in this thesis was to come to a deeper understanding of clinical decision making from within the interpretive paradigm. The project draws on ideas from a number of schools of thought which have the common emphasis that the interpretive use of language is at the core of all human activity. This research project studied settings where health professionals and medical students engage in clinical decision making in groups. Settings included medical students participating in problem-based learning tutorials and a team of health professionals working in a multidisciplinary clinic. An underlying assumption of this project was that in such group settings, where health professionals are required to articulate their clinical reasoning for each other, the individuals involved are likely to have insights that could reveal the nature of clinical decision making. Another important assumption of this research is that human activities, such as clinical reasoning, take place in cultural contexts, are mediated by language and other symbol systems, and can be best understood when investigated in their historical development. Data were gathered by interviews of medical students and health professionals working in the two settings, and by non-participant observation. Data analysis and interpretation revealed that clinical decision making is primarily a social and linguistic skill, acquired by participating in communities of practice called health professions. These communities of practice have their own subculture including the language game called clinical decision making which includes an interpretive repertoire of specific language tools and skills. New participants to the profession must come to embody these skills under the guidance of more capable members of the profession, and do so by working through many cases. The interpretive repertoire that health professionals need to master includes skills with words, categories, metaphors, heuristics, narratives, rituals, rhetoric, and hermeneutics. All these skills need to be coordinated, both in constructing a diagnosis and management plan and in communicating clinical decisions to other people, in a manner that can be judged as intelligible, legitimate, persuasive, and carrying the moral authority for subsequent action.

<p>A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today’s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. </p><p>We investigate how to create a software gate-level simulator able to simulate a high number of gates fast. This involves a trade-off between memory requirement and speed. A compact netlist representation can utilize cache memories more efficient but requires more work to interpret, while high memory requirements can limit the performance to the speed of main memory. </p><p>We have selected the Counting Algorithm to implement the experimental simulator MICA. The main reasons for this choice is the compact way in which gates can be stored, but still be evaluated in a simple and standard way. </p><p>The report describes the issues and solutions encountered and evaluate the resulting simulator. MICA simulates a SPARC architecture processor called Leon. Larger netlists are achieved by simulating several instances of this processor. Simulation of 128 instances is done at a speed of 9 million gates per second using only 3.5MB memory. In MICA this design correspond to 2.5 million gates.</p>

This project explores a reinterpretation process of a deindustrial site through landscape architecture. By using the industrial process to guide the formation of the landscape, spaces, and experiences, a semi-abandoned industrial site is transformed into a cultural park. The purpose of the project is to articulate the intriguing qualities of a deindustrial site and respond to them through a design process that is sensitive to the history and character of the site, while allowing contemporary uses and experiences to evolve. / February 2008

Contemporary urban planning emphasizes the need for practice to be collaborative and communicative. It stresses on the importance of public engagement and participation. To ensure informed participation, planners need to provide relevant information to the public. However, the relevance of that information depends on an understanding of the existing discourse about the issue of interest. My research examined Transit City as a case study to demonstrate how that understanding can be gained. The question that framed the research was: What are the characteristics of discourses surrounding urban planning issues? The research focused on examining media coverage to gain that understanding for two reasons. Firstly, the media are considered to be the main purveyors of public discourse. However, there are limitations in the way they represent issues as this research found. Secondly, the media play an informant role, however imperfectly, on topics that matter. In part, this role gives them their importance and influence. The research examined media discourse surrounding Transit City in 94 articles in National Post, the Toronto Star, CUTA Forum, and Ontario Planning Journal to answer the research question. Discourse analysis was used as a method to investigate the topic under the framework of interpretive policy analysis. The research found that four of the media outlets used discursive practices of representation that highlighted certain themes and excluded others. It also found that the discursive communities that were identified in the media discourse interpreted Transit City differently through their discursive frames that were informed by their interest and responsibility in regards to Transit City and their core belief systems. As such their “argumentative logic” highlighted some aspects of Transit City and excluded others in the debate that ensued. The understanding of such characteristics of discourse can help planners in two ways. First, it informs the planning and the tailoring of messages they relay to discursive communities of various relevance. It allows them to have a stronger participation in the shaping of media discourse and generation of informed debate in the public as well as the professional sphere. Second, it can help planners in developing solutions to address points of controversy and bridge differences among stakeholders effectively in their role as mediators and consensus builders. Both benefits have positive implications in creating informed participation and making the planning process a collaborative and communicative effort.
