Background: The digitalisation and rise of social media completely transformed the dynamics of communication where marketers lost full control over the marketing message to consumers. Companies have adapted by utilising Online Brand Communities (OBCs) with an open environment facilitating their consumer relationship with mutual benefits. Recently, companies have started to fear social media, due to the increased spread of negative word-of-mouth (WOM). Recent research reveals that consumers are more prone to share negative WOM than positive WOM, where certain consumers intentionally seek to harm brands by spreading misinformation. This underscores the need for further exploration of the dark side of OBCs.    Purpose: This paper aims to investigate the presence and impact of negative WOM within OBCs focusing on negative expressions concerning product quality, identity and intention. Specifically, it examines what negative expression has the most significant impact on consumer outcomes in the form of loyalty, intention and emotional attachment. Method: A mixed methodology approach was conducted for this study. The qualitative approach involved conducting a netnography to analyse the dynamics within OBCs and identify negative comments present within the communities. The quantitative approach was then implemented through a survey, incorporating the selected comments from the netnography to understand their impact on consumer outcomes.  Conclusion: The netnography findings showed that negative expressions regarding product quality were predominant within OBCs. The survey revealed that negative expressions concerning consumer identity exert the most significant impact on consumer outcomes. Although product quality discussions dominate OBCs, it was shown to not be the ultimate factor to impact consumer outcomes.

The growth of the ecotourism industry has resulted in increased demand for ecotourism and, consequently, the demand for one of the most renowned ecotourism destinations in South Africa, the Kruger National Park. Eco-tourists are highly educated and expect information-rich experiences which can be addressed with interpretation services. Previous studies indicated that the Kruger National Park‟s management neglects the importance of interpretation and, thus, the expectations of interpretation services exceeded the actual experience thereof. Additionally, the Kruger National Park is faced with a decline in public funding and consequently shifted their focus to ecotourism management to support successful conservation management of the park. Interpretation, however is not only considered to be an important educational tool that addresses visitors‟ expectations for educational services, but also contributes to national parks‟ conservation mandate since it influences visitors‟ behaviour to be more in line with respect for the environment, philanthropic support for conservation and general environmental behaviour. Clearly the Kruger National Park should address interpretation services with the aim of addressing visitor expectations but also to contribute to conservation management. The aim of this study is therefore to develop an interpretation framework for the Kruger National Park. To achieve this aim, this study made use of a self-administered questionnaire which was distributed in the southern and northern regions of the park during December 2011 and June 2012 respectively. Only one questionnaire per travelling group was distributed and resulted in 855 completed questionnaires for this study. Furthermore, the aim of the study was realised by means of several objectives. The first objective was to conduct a thorough literature analysis on the components, theories and goals related to interpretation within ecotourism related products. This was accomplished in Chapter 2 and provided a conceptual framework which was tested in the subsequent chapters to provide an interpretation framework for the Kruger National Park. The second objective explored all the methodological considerations for the subsequent chapters (i.e. articles). Due to the limited space available in the articles, Chapter 3 provided additional information or methodological considerations not captured in the articles of the study. The third objective of this study determined the interpretation expectations and experiences of visitors to the Kruger National Park. This was done in Chapter 4 of the study. Factor analyses revealed visitors‟ expected and experienced interpretation services and compared these factors by means of paired sample t-tests for the park as a whole as well as between the northern and southern regions of the park. The results revealed that there is a gap between visitors‟ expectations and experiences with interpretation services of the park, however, there are no significant differences between the northern and southern regions‟ interpretation services. In addition to determining the visitors‟ expectations and experiences with the Kruger National Park‟s interpretation services; the fourth objective determined market segments for the Kruger National Park based on expected interpretation services. This was accomplished in Chapter 5 of the study by means of cluster analyses (i.e. hierarchical and non-hierarchical) that revealed four distinct markets (i.e. Inquisitive, Eager, Comfort and Quasi-interested seekers). A factor analysis also determined several motivations for visitors to visit the Kruger National Park and by means of ANOVAs and Chi-square analyses, the differences between the market segments based on socio-demographic and behavioural characteristics as well as motivations, expected and experienced interpretation services were determined. The fifth objective of this study determined whether the Kruger National Park‟s interpretation services have an impact on the visitors‟ behaviour to be more in line with the park‟s conservation practices and was accomplished in Chapter 6. This chapter made use of structural equation modelling to determine the multiple relationships between expected interpretation services as well as attitudes and behaviour. Results revealed that visitors to the Kruger National Park are inclined towards positive attitudes towards conservation practices but that the current interpretation services influenced the attitudes as well as the behaviour of visitors negatively and needs to be addressed. Lastly, the results of this research suggest several recommendations for the Kruger National Park as explained in Chapter 7 of this study. Clearly the Kruger National Park needs to address the gap between interpretation expectations and experiences by planning for interpretation in the form of a policy or strategy. The interpretation policy or strategy should also be re-evaluated and amended periodically since visitor‟s needs and markets change. An interpretation framework is presented for the Kruger National Park based on the results of this study to address the current dilemmas of the park in terms of interpretation. Not only did this study provide practical contributions to the Kruger National Park but made several distinct contributions. An interpretation framework was developed that can not only assist the Kruger National Park but which also contributes to the body of knowledge on the topic and can also assist other ecotourism destinations in the same position as the Kruger National Park. This study also confirmed a general classification of interpretation services as well as suggested interpretation typologies that can be used for future ecotourism research. Since there was no guideline available to segment interpretation visitors, this study also made a methodological contribution by proving that expected interpretation can be a viable segmentation base and that the selection of a variable should be based on statistical calculations. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2015

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.

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
