Doctor of Philosophy / Department of Hospitality Management and Dietetics / Deborah D. Canter / SooCheong Jang / Senior casino gaming has been appearing as a leisure activity for the senior population as well as a research topic for many researchers from various academic disciplines. Finding out important reasons or motivations for older adults spending time in casino gaming will be the one of the fundamental ways to determine their future casino patronage intention. Accordingly, this study identifies a comprehensive inventory of senior casino gaming motivations by way of an exploratory approach. Followed Churchill’s (1979) scale development procedure, the study generated a to find five distinctive senior casino gaming motivation dimensions: winning and thrill, socialization, escape, enjoyment, and curiosity. Ultimately, confirmatory factor estimates supported that the finalized measure was unidimensional, reliable, and valid while the measurement scale was parsimonious and captured various dimensions of senior casino gaming motivation. The second part of this study investigated the applicability of an extended theory of planned behavior (TPB) with motivation component attached in context of senior casino gaming behavior. Seniors’ past casino visit was also tested for a moderator effect between the major predictor variables (attitude, subjective norms, perceived behavioral control, and motivation) and seniors’ casino behavioral intention. The findings of a structural equation modeling suggested that all predictable variables of TPB had positive effects on seniors’ casino gaming intention. Among senior casino gaming motivation, ‘winning and thrill’ and ‘enjoyment’ had direct positive effects on behavioral intention. The results of metric invariance test for moderating role of past casino visit showed that there was no indication of seniors’ past casino visit having any influence on their intention to participate in casino gaming. The overall study results suggested that the proposed extended model is a useful tool to use in studying of senior casino gaming behavior. In conclusion, theoretical and practical implications of the study findings were discussed.

Recently, it has been admitted by many researchers that students today are "digital natives" who already utilize several different technologies everyday with different purposes. Furthermore, while there is a plethora of research about learners' perceptions in language pedagogy, there is a paucity of information and research that could move beyond generic perception studies especially regarding new technologies. Accordingly, educators are still concerned not only with how to encourage EFL learners to adopt emerging technologies that could be invaluable in their language learning processes, but also with how to keep students interested in what they are learning. Thus, an understanding beyond students' perceptions with a purposive focus on their approach to technology by also exploring factors that have an influence on their adoption of emerging technologies is the key to knowing how to motivate students to integrate new technologies, and how to keep students interested in the learning process. Therefore, the purpose of this study was three-fold: to identify language learners' approaches to technologies; to examine their attitude toward emerging technologies with a focus on their familiarity, actual use, intentions and perceptions; and finally to analyze the factors and relationships among these factors that best predict language learners' intentions and decisions to use emerging technologies. The study specifically aimed to explore the following emerging technologies: (a) social networking, (b) mobile learning, and (c) digital games as major emerging technologies of today with also a focus on other emerging technologies: (a) augmented reality, (b) wearable technologies, (c) virtual assistants, (d) massive online open courses, (e) 3D printing and (f) online language learning platforms. This mixed methods study benefitted from multiple disciplines, and presented several different perspectives to achieve its aim. The data were obtained through a survey, open-ended questions, and semi-structured interviews. The quantitative data were analyzed through descriptive and inferential statistics. In addition, structural equation modeling was utilized and path analysis was employed to draw on two complementary frameworks: innovation diffusion theory (Rogers, 2003), especially its application in technology adopter categories (TACI) (Dugas, 2005), and the decomposed theory of planned behavior (DTPB) (Taylor & Todd, 1995), which was adapted for this research. The qualitative data was analyzed through thematic content analysis, and used to triangulate and affirm what the quantitative data was showing. The findings indicated that technology adopter categories were normally distributed among EFL learners at a public and a private university in Turkey. Although most EFL learners were quite familiar and confident with major emerging technologies, they were not very familiar with minor emerging technologies. As for an awareness of the benefits of all listed emerging technologies, the study revealed that EFL learners' awareness is quite high; however, it was also found that participants' intention to use these emerging technologies and their actual use were very low. Finally, the results showed that the adapted DTPB was useful in explaining much of the variance in the intention to integrate technology into language learning processes by EFL learners, and attitude was the most important predictor and factor of behavioral intention. Given these findings, this research aims to contribute to the literature in innovation diffusion, user adoption and language pedagogy by offering several theoretical, methodological, and pedagogical implications and directions for future research and applications.

The purpose of this creative project was to develop a conceptual landscape plan for integrating residential development on an historically significant property, located at North Bend, Ohio, known as "Aston." The plan, designating areas suitable for residential development, was designed so that most of the features and elements of the property that defined its historic character were not destroyed or, at least, not unreasonably compromised. Priority was also placed on protecting the aesthetic and environmental qualities of the site. An inventory of the existing physical attributes (soil and bedrock geology, surface hydrology, topography, structures and other built features, etc.) of the property was conducted focusing on identification of historically significant elements. Additionally, written and photographic documentation established the general historic character and appearance of the property and identified important features that were no longer present in the current landscape. The documentation of the history of the property and its historic features was presented in narrative form (supported by historic and current photographs) in this study. It is probable that further documentation of this significant property is unlikely to occur since it is presently owned by a development company. The two areas of the property that were found to contain concentrations of historic resources (structures, drives, vegetation, walls, ponds, etc.) were designated as "Historic Core Areas" for preservation. Another area where the Ohio Department of Natural Resources had discovered a population of an endangered plant species was also withdrawn for preservation. Based on the implications of the physical attributes of the property, further areas were designated as unsuitable for development and will function as open "greenspaces" for the proposed community. The remaining acreage of the property constituted the areas designated as suitable for residential development. In these areas, the suggested road layout, lot sizes, siting of condominiums or housing structures, and pedestrian trails were designed. Finally, recommendations for guiding the more detailed design of the architectural and landscape architectural elements of the proposed residential development were presented. This completed creative project presents a suggestion for how modem residential development may be accommodated without substantially destroying the documented historic, environmental and aesthetic values of this significant property. / Department of Landscape Architecture

Rheumatoid arthritis (RA) is a chronic, progressive autoimmune disease causing inflammation of the synovium resulting in severe pain, joint disfigurement and disability as well as malaise, fatigue and a depressed immune system. Treatment consists of three broad phases; firstly, following diagnosis treatment is focussed on rapid reduction of pain and inflammation. Secondly, maintenance of quiescence is sought through medication. Finally, if disease activity remains high despite medication, escalation to anti-TNF α therapy is required to prevent permanent joint damage and disability. The primary course of treatment is prescription of disease modifying anti-rheumatic drugs (DMARDs) within 3 months of onset of symptoms. However, DMARDs can take 8-12 weeks to exhibit a noticeable benefit whereas unpleasant side effects can occur shortly after initiation. Also, DMARDs do not alleviate pain; therefore it is difficult for patients to attribute recovery to this medication. For these reasons, although it is imperative for future health and functioning to take DMARDs as prescribed, non-adherence is common at 30-50%. Non-adherence to treatment can be intentional, where a decision is made not to conform to the prescription, or unintentional which is often due to forgetting. To measure intentional non-adherence, a validated measure of adherence for rheumatoid arthritis was reduced through exploratory factor analysis from 19 items to 5 items by removing items that did not add to the explained variance of adherence. The CQR5 explained 53% of the variance in adherence and was shown to have a good fit to the data through confirmatory factor analysis. A discriminant function equation was generated that correctly identifies 88.5% of patients as high or low adherers and has high clinical utility due to the brevity for patients and unidimensionality for easy interpretation. The CQR5 was used throughout the programme of research to measure intentional non-adherence along with a separate measure of unintentional non-adherence. Four commonly used social cognition models of illness were measured in 227 RA patients to determine which had the best utility for predicting non-adherence to DMARDs. Patients were recruited to represent the three stages of illness including newly diagnosed, established on DMARD therapy and established with concurrent anti-TNF α therapy. Logistic regression analysis showed that the Self Regulatory Model best predicted intentional non-adherence as patients with perceptions of worse consequences of RA and longer disease duration were more likely to be highly adherent to DMARDs in cross-sectional analysis. In contrast, the Theory of Planned Behaviour better predicted patients who self-reported forgetting their DMARDs with patients with more confidence in being able to take their medications (Perceived Behavioural Control) being less likely to forget. 171 patients were successfully followed-up six months after baseline recruitment. The longitudinal results showed that the social cognition models differed for patients at different stages of the illness suggesting that their experience of living with rheumatoid arthritis influenced perceptions of their illness and medications. Newly diagnosed patients scored lower on factors measuring perceptions of disease chronicity and seriousness whereas patients that had escalated to anti-TNF α therapy scored higher on these factors. The newly diagnosed patients also showed more variability in the social cognition scores whereas the more established patients demonstrated stable models of illness. This supports Leventhal’s (1992) theory that illness representations will be regulated through integration of knowledge and experience of an illness. Structural equation modelling was used to establish the best predictors of intentional non-adherence at six month follow-up. In support of research in other chronic illnesses (Horne & Weinman, 2002; Niklas, Dunbar & Wild, 2010), the effect of perceptions of the consequences and chronicity of the illness on adherence are mediated by perceptions of the necessity of the medication. In addition, the impact of the emotional reaction to the illness on adherence to DMARDs is mediated by concerns about the medication. In addition, this study incorporated factors from the Theory of Planned Behaviour to explain medication adherence and found that the influence of friends and family impacts on the patient’s confidence to follow the prescription accurately which in turn as an effect on adherence to DMARDs. This large longitudinal study found that by combining factors from a number of social cognition models, it is possible to explain and predict intentional non-adherence and provides some evidence for best ways to intervene to improve adherence and prognosis. To provide a more comprehensive and clinically useful picture of non-adherence, a Cost of Illness study was carried which found that patients self-reporting low adherence to DMARDs also had significantly higher costs for this medication. This was caused by an increased incidence of Leflunamide prescribing for patients who often forget their medication and was maintained longitudinally. This association has not been previously reported in the literature and provides some evidence that non-adherence to DMARDs is having a concrete effect on the clinical management of patients. Finally, an SMS text message based reminder service designed to remind patients who self-report forgetting their medications was tested through a simulation study for the cost and likely benefit in health related quality of life using the health economic analysis of the longitudinal study and the results of a survey establishing the feasibility of implementing such a service in the rheumatology clinic. A sensitivity analysis testing the number of messages sent and the cost per message found that a reminder service for the sample of patients in this programme of research would cost between £1387.00 and £142.27 per year. This would equate to a cost per Quality Adjusted Life Year (QALY) gain of between £2889.58 and £296.40 by enabling patients to adhere more rigorously to their DMARD regimen. This programme of research is the first to test four commonly used social cognition models to predict adherence to DMARDs in a large, multi-centre longitudinal study of rheumatoid arthritis patients. Perceptions of the likely duration and consequences of the illness, as measured by the Illness Perceptions Questionnaire and the necessity of medications (measured by the Beliefs about Medications Questionnaire) along with self-efficacy (measured by the Theory of Planned Behaviour) explained 24% of the variance in intentional adherence over six months. The results show the importance of considering intentional and unintentional non-adherence separately as they appear to have different underlying mechanisms as well as patients in different phases of the illness as their experience influences their social cognition models of illness. A simple SMS based reminder service could act as a cue to action to reduce unintentional non-adherence whereas addressing issues surrounding maladaptive perceptions about the illness and the treatment could improve intentional non-adherence which has the potential to improve the prognosis and quality of life for patients as well as safe costs for the NHS.

This study evaluates the adoption of Open Source Software (OSS) by IT Small to Medium-sized Enterprises (SMEs) in the UK. The growing popularity and acceptance of OSS continues to draw much attention in research and practice. However, researchers and IT practitioners within the UK SME sector still face challenges in understanding the issues that influence the acceptance, adoption, and diffusion of OSS. While previous research studies have focused mainly on the software development model and the unique characteristics of OSS, the area of OSS adoption by UK SMEs has largely been ignored. Furthermore, there is a lack of widely-acceptable theories that explain the adoption of OSS, implying that there is limited understanding of OSS adoption by UK SMEs. This gap in research has led this thesis to evaluate existing adoption theories and then apply the 'Decomposed Theory of Planned Behaviour' to model the adoption of OSS by SMEs. Based on the emerged conceptual model, an innovative and structured qualitative research design that uses a case study strategy was developed to evaluate the adoption of OSS across 10 UK SMEs in the IT industry. The analysis of the standardised data from the case study interviews led to the definition of the 16 factors of an emergent theory of OSS adoption by IT SMEs. The analysis of that empirical model has led to important conclusions including the following five issues, summarily. (1) The participant IT SMEs were drawn to different benefits, and experienced different challenges, in using OSS, suggesting that there is subjectivity and complexity in the factors influencing OSS adoption. (2) As in most Information and Communication Technology (ICT) adoption, ITcapability was identified to be essential for successful adoption of OSS, and therefore, it presents potential for important cooperative and collaborative support with OSS communities. (3) The emergent theory from this research study provide researchers and practitioners with variables for surveying critical-success-factors and a reference model for understanding the adoption of OSS. (4) The emergent theory and other general findings from this study are likely to have relevance in other areas of Information Systems research and practice, owing to the factors and theoretical framework that are common to OSS and general ICT acceptance, adoption, and diffusion. (5) This study appears to be the first that has focused on developing a widely-acceptable theory of OSS adoption by IT SMEs in the UK, suggesting that this innovative research study is a novel contribution that has important implications for theory and practice in OSS and general ICT acceptance, adoption, and diffusion.

Background: The prevalence of disability increases with age; therefore with an aging population, interventions to reduce disability are crucial. This thesis adopts a behavioural conceptualisation of disability. The theoretical frameworks of the International Classification of Functioning, Disability and Health (ICF), the Theory of Planned Behaviour (TPB) and the integrated ICF/TPB model are applied to investigate disability and physical activity (PA) behaviours. The thesis aims to: (1) identify the factors involved in the prioritisation of patients for total joint replacement; (2) classify patient pre-operative expectations of total hip replacement (THR) and investigate the relationship between expectations and recovery after surgery, and; (3) test whether the TPB and theory-based interventions can predict and explain PA within individuals. Method: Five studies were conducted. In the first study, health professionals judged whether the items from two prioritisation tools measured each of the ICF constructs. In the second study, surgeons ranked patient vignettes, which differed by constructs from the integrated model, in order of priority for THR. In the third study, a large cohort of THR patients reported expectations of surgery pre-operatively. Health and functioning were also reported pre-operatively and 1-year post-operatively. The fourth and fifth studies were a series of experimental n-of-1 studies using diary methods assessing TPB cognitions and PA behaviours. Results: There is a lack of agreement between judges in relation to the content of many of the items from prioritisation tools. Behavioural and psychological factors can influence prioritisation for THR. The majority of patient expectations of THR addressed activities and social participation; however, the evidence for a relationship between expectations and recovery was limited. The TPB can predict PA within some individuals but the evidence in support of interventions to increase PA was limited. Discussion: The findings provide important clinical and theoretical implications for understanding disability and physical activity behaviours.

The aim of this research is to investigate the extent to which Open Source Software (OSS) adoption behaviour can empirically be shown to be governed by a set of self-reported (driving and inhibiting) salient beliefs of key informants in a sample of organisations. Traditional IS adoption/usage theory, methodology and practice are drawn on. These are then augmented with theoretical constructs derived from IT governance and organisational diagnostics to propose an artefact that aids the understanding of organisational OSS adoption behaviour, stimulates debate and aids operational management interventions. For this research, a combination of quantitative methods (via Fisher's Exact Test) and complimentary qualitative method (via Content Analysis) were used using self-selection sampling techniques. In addition, a combination of data and methods were used to establish a set of mixed-methods results (or meta-inferences). From a dataset of 32 completed questionnaires in the pilot study, and 45 in the main study, a relatively parsimonious set of statistically significant driving and inhibiting factors were successfully established (ranging from 95% to 99.5% confidence levels) for a variety for organisational OSS adoption behaviours (i.e. by year, by software category and by stage of adoption). In addition, in terms of mixed-methods, combined quantitative and qualitative data yielded a number of factors limited to a relatively small number of organisational OSS adoption behaviour. The findings of this research are that a relatively small set of driving and inhibiting salient beliefs (e.g. Security, Perpetuity, Unsustainable Business Model, Second Best Perception, Colleagues in IT Dept., Ease of Implementation and Organisation is an Active User) have proven very accurate in predicting certain organisational OSS adoption behaviour (e.g. self-reported Intention to Adopt OSS in 2014) via Binomial Logistic Regression Analysis.

La métropole est polychronique. L'isolement d'un de ses rythmes permet de nuancer les théories de la modernité liquide et de la ville en continu. À travers l'étude de trois événements festifs métropolitains à Paris et Bruxelles, nous proposons une lecture de l'histoire urbaine par ses temps partagés, une description des mécanismes par lesquels les rythmes sociaux émergent et une analyse de leur rôle social et spatial. Réinterrogé par le concept de rendez-vous collectifs, les rythmes urbains sont une co-production entre un urbanisme temporaire et une urbanité événementielle. Ces deux éléments explique le double rôle spatial et social des rythmes événementiels. Les institutions municipales instrumentalisent l'urbanisme temporaire pour signifier le temps, organiser le rassemblement et produire du lieu. L'urbanité événementielle est le résultat des interprétations individuelles des événements comme signe temporel qui produit du lien social et un sens commun des lieux. La répétition de la rencontre entre l'urbanisme temporaire et l'urbanité événementielle provient d'une part, de la décision politique de d'instrumentaliser le rendez-vous dans l'organisation urbaine, d'autre part de la synchronisation des individus qui organisent leurs temps pour participer au rassemblement. La rationalité qui anime les participants est motivée par la valorisation des interactions de face-à-face et la production de liens sociaux associatifs, dans une société interrogée par la différenciation et la désynchronisation des modes de vie. L'individu ne se passe pas de rassemblements rituels, dans des lieux et selon des temporalités saisonnières. Ces rythmes collectifs sont adaptés à la métropole, à la complexification de ses territoires, à l'hybridation de ses représentations culturelles et à l'individualisation de ses temporalités. Au-delà, le concept de rythme est une théorie de morphologie sociale qui rend compte du fonctionnement des sociétés de façon multiscalaire et dynamique. Elle s'inscrit dans les théories sociologiques intermédiaires qui lient l'individu et le collectif, l'habitant et les institutions, la morphologie spatiale et temporelle de groupements humains de toutes tailles. Le fait métropolitain, influençant et influencé par l'individu et le global, constitue une échelle mésociale heuristique / The city is polychronic. We qualify liquid modernity theory and the twenty-four hour city model by isolating one of its rhythms. Based on a diachronic study of three festive urban events in Paris and Brussels, we propose a new reading of urban history through planned gatherings, a description of the mechanisms by which social rhythms emerge and the role they play in building urban space and society. The planned gathering concept is applied to urban social rhythms, which are seen as the product of an interaction between temporary urbanism and event sociability. Institutions instrumentalise temporary urbanism to signify units of social time, and implicitly plan gatherings by producing a conducive physical place. Event sociability is the collective result of individual interpretations of this sign, which produce social ties and create a corresponding social place. These places become periodic through political decisions to reproduce the sign, as w ell as individuals' efforts to organize and synchronize their time to participate. The resultant planned gatherings are in turn instrumentalized to organize the metropolis. In a society whose groups are increasingly differentiated and desynchronized, face-to-face interaction and the production of discretionary social ties are highly valued. Individuals apply value rationality and thus continue to participate in ritual, seasonal gatherings at fixed places and times. Despite historical continuities, these rhythms are specifically modern in that they have adapted to the contemporary city's territorial complexity, cultural hybridization, and idividualized temporality. Using the semantic duality of rhythm (flowing / periodic) we outline a more general theory of social morphology which provides a multiscale, dynamic account of societies, covering interactions between the individual and the collective, inhabitants and institutions, the spatial and temporal patterns in human groups of varying size. The mesosocial metropolitan scale is situated between the indivual and the global

Widespread adoption of plug-in electric vehicles (PEVs) can help to achieve deep reductions in global greenhouse gas emissions; however, the degree to which this potential will be realized depends on consumers’ decisions to purchase these vehicles over conventional ones. To provide comprehensive insight into the psychological and contextual influences on consumer vehicle preferences, three studies were performed using a mixed-methods approach. Study 1 employed a survey and stated choice experiment to explore: 1) the explanatory power of the three psychological variables from Ajzen’s (1991; 2005) theory of planned behaviour in predicting PEV purchase intentions among new vehicle buyers from British Columbia, and 2) the influence of hypothetical variations in financial and non-financial incentives on estimated PEV preference, with the goal of informing the design of provincial policy measures. Vehicle preferences were most strongly influenced by purchase price and point-of-sale incentives – with a roughly 4% forecasted increase in PEV new vehicle market share under a $5,000 purchase rebate – as well as by attitudes about PEVs (especially concerning personally-relevant PEV benefits), perceived behavioural control, and social norms. In Study 2, a latent class choice model was used to integrate survey and choice experiment data to characterize consumer classes based on vehicle preferences, demographic characteristics, and psychological variables. Findings revealed profiles of five distinct preference-based segments and demonstrated that the inclusion of psychological covariates can improve the fit of such latent class models. Study 3 extended these findings through a controlled message framing experiment that evaluated the impact of psychological distance on PEV purchase intentions. Results demonstrated that messages emphasizing both personally-relevant and societally-relevant PEV benefits increased related purchase intentions compared to the control group. Taken together, these findings may be useful in the development of PEV policies as well as targeted marketing and communications strategies aimed at supporting a transition to PEVs within Canada. / Graduate / 0451 / 0621 / 0709 / christine.kormos@gmail.com
