This research project addresses the following: how topical talk operates in the organisation and management of MSE interactions; and how topical talk operates in the co-ordination of specific service requests and service provisions. It draws on a corpus of audio-recorded and transcribed interactions between general practitioners and persons seeking general medical services in suburban clinics in Brisbane, Australia. The corpus comprised a total of 67 medical service events (henceforth MSEs), audio-taped with the full informed consent of the participants. Many contemporary medical sociological accounts of the operation of topical talk in MSEs, typified by the work of Mishler (1981, 1984) and Waitzkin (1991), remain anchored to the 'professional dominance' thesis (Freidson 1970a; 1970b), arguing for the fundamental conflict between two perspectives - lay and professional. Topical talk has been formulated as one expression of this conflict in 'doctor-centred' communicative 'styles' (Byrne and Long 1976; Silverman 1987). Within such accounts, familiar interactional patterns in MSEs, including the content and structure of topics, have been theorised as instruments of power and control whereby the dominance of specialised medical knowledge and expertise are established and maintained. Mishler's (1984) characterisation of the conflict between a biomedically oriented 'voice of medicine' used by professional physicians (henceforth GPs) and a 'voice of the lifeworld' used by persons seeking medical services (henceforth Ps) is an expression of the 'professional dominance' thesis. The voices are characterised as attesting to a fundamental, theoretically problematic, asymmetry of power relations between GPs and Ps, thereby reinforcing the ideological status of professionals in general and the medical profession in particular. Further, recommendations regarding correctives to 'professional dominance' centre on advice GPs to attend to the primacy of Ps' talk on their experiences of illnesses rather than apparently 'ignoring' or transforming these topics into biomedical accounts of disease. This research project critiques this formulation of topical talk and the traditional theoretical and empirical bases on which it has drawn. This critique arises from the application of ethnomethodological approaches to the study of MSEs. Such approaches, as outlined in Chapters 2 and 3, are characterised by a number of conceptual and analytic premises: First, particular social structural features of social activities and the institutional contexts within which activities occur should not be assumed to be the primary criteria for judging the import and adequacy of situated action. Second, the parties to situated social events mutually constitute those events in the real world. Third, issues of agency are collaborative situated accomplishments such that the management of everyday social activities is accomplished by the people involved who show one another the rationalities of their actions as they assemble the familiar scenic features of those same institutional events (Garfinkel 1967; Sacks 1992a, 1992b). These assumptions have been applied in ethnomethodological analyses of social action, including the analysis of professional service encounters that have critiqued the 'professional dominance' thesis (Eglin and Wideman 1986; Sharrock 1979). The novelty of this study is the analysis of the operation of topic organisation as a phenomenon of order. This study also draws on recommendations within Ethnomethodology (Hester & Eglin 1997b; Watson 1997) that sequential and categorial organisations are mutually informative in the analysis of the rationality of situated social action. One of the particular contributions of this thesis is that it not only jointly applies both conversation analysis and membership categorisation analysis but also extends this recommendation to the inclusion of topic analysis as was originally provided for by Sacks (1992a , 1992b) and Garfinkel and Sacks (1970). Within this study a model of analysis has been constructed that has enabled the analytical consideration of four dimensions of social organisation: local sequential, extended sequential, topical and categorial organisations. The theoretical and empirical concepts of ethnomethodogical analysis have thus been developed and extended within this project. The central findings of this study are that in institutional service events, the 'service topic' is both significant and consequential, and that persons constitute themselves as bona fide incumbents of the categories GP or P by attending to their actions as topically organised. The local adequacy of any particular interactional move (such as questioning-answering, greetings, the design of a topic proposal, etc) is shown to be referenced to the service topic. This study found no evidence of potential or actual "struggles" between the 'voice of the life-world and the voice of medicine'. Rather, this study finds routine recognition on the part of both Ps and GPs of the centrality of the service topic and, thereby, the service task, and no evidence of orientation to distinctive biographical contributions staged in competition with biomedically relevant service topics. It is found that Ps' biographical references were made in the context of an assembled service topic such that particular service tasks, however conventional, were constituted as both relevant and reasonable as medical goods and service for the specific service recipient and provider. At the most general level, it is concluded that the service topic operates as a phenomenon of order in MSEs where order, as defined by Garfinkel and Weider (1992: 202), refers to all of the rationalities evident in the generic features of institutional events and settings, that is, the situated logic and intelligibility as well as the procedures whereby they are constituted as recognisable social events. The thesis concludes with a discussion of the implications of the findings for the theorisation, policy-making, medical education, and practices of GPs and Ps within MSEs. Overall, the significance of this work for researchers into medical interactions is that the relevance of the service topic and its pervasive organisational consequences need to be considered analytically. A major outcome of this thesis is the establishment of a new order of interest within the study of institutional interactions. The project demonstrates the pervasive consequences of service topics and thus provides a step forward in the study of institutional service interactions and ways of theorising their rationality, a step that extends beyond social structural pre-theorisations of power and domination and also beyond interactional accounts of the primary relevance of turn taking structures.

However, no technique studied to date can solve definitively the problem. Differences in dynamic systems, whether linear, nonlinear, variant or invariant in time, with physical or analytical redundancy, hamper research in order to obtain a unique solution . In this paper, a technique for fault detection and diagnosis (FDD) will be presented in dynamic systems using state observers in conjunction with other tools in order to create a hybrid FDD. A modified state observer is used to create a residue that allows also the detection and diagnosis of faults. A bank of faults signatures will be created using statistical tools and finally an approach using mean squared error ( MSE ) will assist in the study of the behavior of fault diagnosis even in the presence of noise . This methodology is then applied to an educational plant with coupled tanks and other with industrial instrumentation to validate the system.

La capacidad y las buenas prácticas de producción son base para el desarrollo de las empresas y más con la competitividad actual. Por ello, el caso de estudio presentado analiza las operaciones de una MYPE peruana del sector plástico, que habría dispuesto previamente mudarse a una nueva planta. En base a un diagnóstico se identificó un déficit en su capacidad de producción con costos representativos equivalentes al 9% de su facturación anual, derivados de la falta de máquinas e ineficiencias, las cuales aun siendo solucionadas no permitirían satisfacer la demanda, por lo que se confirmó que la decisión de la empresa era correcta. De tal forma, se planteó un proyecto que permitiría el diseño de las nuevas instalaciones de la empresa en un local de mayores dimensiones, con el objetivo de optimizar su capacidad de producción y evitar que las malas prácticas detectadas en la actualidad se repitan, validando su viabilidad mediante un prototipo virtual. Asimismo, en base a los cálculos se lograría aumentar la capacidad instalada en 53.5%, superando a la demanda proyectada dentro de tres años en un 24.90 %, lo que permitiría un mayor crecimiento organizacional en el futuro. / The capacity and good production practices are the basis for the development of companies and more with the current competitiveness. Therefore, the case study presented analyzes the operations of a Peruvian MSE in the plastics sector, which would have previously arranged to move to a new plant. Based on a diagnosis, a deficit in its production capacity was identified with representative costs equivalent to 9% of its annual turnover, derived from the lack of machines and inefficiencies, which, even being solved, would not allow to satisfy the demand, therefore confirmed that the company's decision was correct. In this way, a project was proposed that would allow the design of the company's new facilities in a larger premises, with the aim of optimizing its production capacity and preventing the bad practices detected at present from being repeated, validating their viability through a virtual prototype. Furthermore, based on the calculations, it would be possible to increase the installed capacity by 53.5%, surpassing the projected demand in three years by 24.90%, which would allow greater organizational growth in the future. / Trabajo de investigación

Lightweight cellular concrete (LCC) is mainly a mixture of water, cement, and foam bubbles. LCC generally has a cast density between 20-60 pcf and an air content between 49-84%. LCC is often used as a fill material because it has a low unit weight which reduces settlement. LCC is increasingly being considered as a backfill behind Mechanically Stabilized Earth (MSE) walls and embankments. Although engineers are using LCC in MSE walls or free face walls (MSE wall without the concrete panels or reinforcements), there is presently a lack of information regarding the performance and behavior of LCC to guide them. This research attempts to answer questions on the design of MSE walls backfilled with LCC and free face LCC walls by providing a well-documented case history and evaluating if LCC can be modeled as a c-ϕ material. A steel frame test box (10 ft wide x 12 ft long x 10 ft high) with a MSE wall on one side was constructed for the research. The box was filled with four lifts of LCC with steel ribbed-strip reinforcements extending into the LCC behind the MSE wall panels at the center of each lift. After the LCC was cured, two static load tests were performed by applying a surcharge load to the surface of the LCC. In one test, surcharge pressure was applied adjacent to the MSE wall to produce failure of the wall system. In a second test, the surcharge pressure was placed adjacent to a free face of the LCC to produce failure. String potentiometers (string pots), load cells, pressure plates, and strain gages were used to measure the behavior of the MSE wall and free face wall during testing. These two tests provided a comparison between LCC behavior with a MSE wall relative to a LCC free face. Failure of the free face wall with unreinforced LCC backfill in this test can be predicted using Rankine’s lateral force equation using a c-ϕ model. Failure angle at the base of the free face wall was between 51-63° which corresponds with an average friction angle (ϕ) of 24° and cohesion (c) of 1575 psf with an upper bound ϕ = 34° and a c = 1285 psf. The presence of reinforcements in the LCC backfill behind the MSE wall increased the capacity of the wall to hold a surcharge load. The presence of reinforcements in the LCC behind MSE walls also led to a much more ductile surcharge pressure vs. lateral deflection curve for the MSE wall compared to the free face wall.

L’industrie des produits de l’érable est particulièrement importante en Amérique du Nord. Elle est touchée par un phénomène naturel qui se produit en fin de saison de récolte. Il s’agit de l’altération du goût du sirop ; un goût fort désagréable se développe et se nomme goût de bourgeon vu qu’il coïncide au bourgeonnement des feuilles d’érable. Des coûts et du temps sont impliqués à sa récolte et sa production. Cependant, un sirop d’érable avec un goût de bourgeon est vendu à moindre prix. Il constitue donc une perte potentielle d'argent pour les producteurs. Au fil du temps, ils ont appris à se fier à des signes distincts de la nature pour déterminer le début du bourgeonnement. Néanmoins, il est important de le détecter hâtivement pour les producteurs et de mieux comprendre les changements moléculaires associés au défaut de saveur de type bourgeon. Plusieurs travaux sur les produits de l’érable ont été effectués durant le dernier siècle, mais ce n’est que récemment que des projets de recherche sont centrés sur le goût de bourgeon. La détection de celui-ci est certes importante, mais il y est aussi question de mieux connaître la variation de la composition du sirop ou de la sève d’érable, afin de mieux comprendre le phénomène. Tel que décrit dans l’introduction de ce mémoire, on connaît maintenant mieux la composition du sirop d’érable, même que quelques solutions ont été proposées à notre problème, mais beaucoup de questions restent sans réponse que ce mémoire tentera de résoudre. C'est dans ce contexte que cette étude se pose. En visant à identifier les molécules responsables du défaut de goût de type bourgeon que l’on peut retrouver dans le sirop d’érable, nous espérons aider à mieux cibler le problème et à mieux comprendre le métabolisme et, éventuellement, comprendre comment ce goût se développe. Dans un second temps, la découverte de molécules pas encore rapportées, au meilleur de notre connaissance, comme étant présentes dans le sirop d’érable est aussi visée, sans égard à la classification du sirop. Les travaux de ce mémoire contribueront, ultimement, à trouver une façon d’empêcher la formation de ce goût et surtout un moyen de l’éliminer. Pour ce, une première partie correspondant à l’analyse des composés volatils a été effectuée par SPME et GC-MS sur 78 échantillons de sirop d’érable. L’analyse statistique des résultats par PCA cible 42 composés et associe chacun d’entre eux au sirop d’érable avec le défaut de saveur ou alors au sirop sans défaut de saveur. Parmi elles, seules 36 ont pu être identifiées par leurs spectres de masse. La seconde partie correspond à l’analyse des composés non volatils par UPLC-QTOF et UPLCMS/MS. La méthode a été optimisée pour cibler les molécules relativement apolaires par rapport aux sucres et aux acides aminés présents dans le sirop d’érable. Au total, 20 échantillons de sirop ont été analysés, dont 10 à défaut de saveurs de type bourgeon et 10 sans défaut. Pour cette partie, l’analyse de composantes principales a encore une fois été utilisée pour classer les types de sirop à l’étude selon les composés détectés. Ainsi, le mémoire avance les connaissances moléculaires liées à l’émergence du défaut de bourgeon dans le sirop d’érable. / The maple products industry is particularly important in North America. It is affected by a natural phenomenon that occurs at the end of the harvest season. It’s the alteration of the taste of the syrup; a very unpleasant taste develops and is called buddy flavour since it coincides with the budding of maple leaves. Costs and time are involved in its harvest and production. When maple syrup is associated with the buddy taste, its commercial value is lower. Therefore, it contributes to a loss of money for producers. Over time, they have learned to rely on distinct signs from nature to determine the onset of budding. However, methods are needed to detect it and research is needed to better understand the molecular changes in maple syrups. Several research projects on maple products have been carried out during the last century, but it is only recently that research projects have focused on the buddy flavour. They focus on determining the variation in the composition of maple syrup or sap, but also on better understanding of the phenomenon. We now know more than ever about the composition of maple syrup, on top of that some solutions have been proposed to our problem, but many questions remain unanswered and it is obvious that there is still so much to discover. It is in this context that this study arises. By aiming to identify the molecules responsible for the buddy flavour defects that can be found in maple syrup, we hope to help on targeting the problem and better understanding the metabolism of maple trees and, eventually, how the buddy taste develops. Secondly, it is aimed at discovering molecules not yet reported, to the best of our knowledge, as being present in maple syrup regardless of the classification of the syrup. This will contribute, ultimately, in finding a way to prevent the formation of this taste and a way to eliminate it. Thus, the first part of this master’s thesis corresponds to the analysis of volatile compounds by SPME and GC-MS on 78 maple syrup samples. Statistical analysis of the results targets 42 compounds and associates them with either maple syrup with flavour defects or with maple syrup with regular flavour maple syrup. Among these, 36 molecules could be identified by mass spectrometry. To extract correlations from our data, the principal component analysis (PCA) ensued. The second part corresponds to the analysis of non-volatile compounds by UPLC QTOF and UPLC-MS/MS. The method has been optimized to target molecules that are relatively apolar compared to sugars and most of the amino acids present in maple syrup. A total of 20 syrup samples were analyzed, including 10 with bud-like flavour defects and 10 with no defects. For both parts, PCA was once again used to determine which types of syrup under study are the compounds associated with. Taken together, the results presented in this master’s thesis advances knowledge on the molecular origins of the buddy flavour defect in maple syrups.

Rapid increases in population ageing and the associated rise in the prevalence of dementia have created many challenges for the care of older people with dementia. As the majority of people now living in residential aged care facilities (RACFs) now have dementia, the need to maximise the quality of life for this group is increasingly recognised. While such issues have attracted research and policy attention in recent years, the evidence base for practice in dementia care is still underdeveloped. The need for more effective therapeutic interventions to improve the quality of life for older people with dementia is recognised, particularly those living in RACFs. The use of pets is one example of recent attempts to help create a more home-like environment and dog therapy is available in many facilities. Well designed research to demonstrate whether it actually has a positive impact on residents’ quality of life is lacking. This study is the first reported randomised controlled trial investigating dog therapy for people with dementia. Fifty-five older people with mild to moderate dementia living in three residential aged care facilities in the Greater Brisbane area participated in this study. The goal was to identify whether dog therapy accrued any benefits to residents’ well being and compare the benefits, if any, with human-only therapy intervention. The main hypothesis was that dog contact delivered in a small group recreational therapy format would have a beneficial effect on the well being of participants. It was additionally hypothesised that prior and current positive relationships with dogs would be related to improved outcomes of dog therapy and support a human-animal bond explanation of relationship development with the therapy dog(s). Participants were randomly assigned into two groups within each facility: The dog therapy group and a human-only therapy group. Session plans were structured according to a recreational therapy format. Three therapy dogs were used (a miniature Poodle, a Staffordshire Terrier and a German Shepherd Dog) with one dog present at any dog therapy session A before-and-after design was used with concealment of participants at allocation. Mixed methods were used including a panel of seven validated psychometric instruments, an observational measure and a series of four novel questionnaires, dogs for older groups with Alzheimer’s (DOGA), developed de novo specifically to investigate the effects of dog therapy on participants within this study. Measures of mood, quality of life, health and psychosocial functioning, collectively referred to as well-being, detected benefits accruing to dog therapy participants compared with human-only therapy that approached significance (p = .056) with a large effect size (partial eta squared 16.6%). A different measure of mood and apathy showed similar improvement for participants of both therapy types trialed with analyses of a smaller dataset (n = 36) revealing an overall highly significant result (p=.008) and large effect size (partial eta squared = 25.6%) for all participants. To explore the perceptions of care staff to the dog therapy intervention, a self-complete semi-structured questionnaire was completed by a sample of 21 from two of the study facilities. Content analysis revealed that staff overwhelmingly supported dog therapy with a total of 84 comments about benefits and 22 about risks. Responses were categorised and then linked into emergent themes: a temporal dimension, sense of self and increased opportunities for self expression. The opportunity provided by the therapy dog for accessible caring physical contact for participants was identified as important. General recreational therapy goals such as improved mood, reminiscence and increased levels of conversation were reported by staff to continue beyond interventions. The observed risks were: confusion over dog ownership, subsequent worry about losing the dog after sessions, jealousy over the therapy dog and one participant did not enjoy the small group format. Participants described their experiences of contact with the therapy dog as “like” above “attached”. Personal preference explanations are therefore supported, rather than “attachment”, to explain outcomes for participants. This suggests the psychosocial approach has greater relevance here than human-animal bond explanations. Effects of previous dog attachment on outcomes were inconclusive but there was some evidence that participants’ relationship with the therapy dog(s) influenced outcomes, though the nature of that relationship has not been clarified. Recommendations from the study findings are that dog therapy be conducted for people with mild to moderate levels of dementia in groups of 3-11 for a duration of around 10 weeks with sessions for 30 minutes held once or twice weekly and according to a standard format. Opportunities for participants to touch, hug and interact directly with the therapy dog should be maximised without compromising dog welfare. The findings suggest that respect for the personhood of participants is important to the success of the therapy types trialled, which further supports psychosocial therapies involving contact with people or live animals for use with people with dementia over those that minimise or exclude it.
