South Africans are engaged in daily battles with work-related and non-work related issues. Although an organisation is not capable of addressing or changing all the issues experienced by the South African population, it can intervene in order to improve the quality of its employees’ working lives. A suggested starting point is person-environment fit (PE fit), due to its effect on job satisfaction and intentions to leave. Consequently, when an individual experiences low PE fit, it will contribute to job dissatisfaction, and intentions to leave as international research has shown. To possibly decrease the impact of these relationships, it is important for leader empowering behaviour to be evident throughout the organisation. The objectives of this study were to determine possible relationships, indirect effects, and moderating effects between PE fit, job satisfaction, intentions to leave, and leader empowering behaviour. A convenience sample of employees working under the guidance of a leader/manager/supervisor was taken from a retail company in Gauteng. Participation in the study was voluntary. A measuring battery measuring PE fit (i.e. person-organisation fit, needs-supplies fit, and demands-abilities fit), job satisfaction, intentions to leave, and leader empowering behaviour (i.e. delegation of authority, accountability, self-directed decision making, information sharing, skills development, and coaching for innovative performance) was used. Descriptive and inferential statistics, Raykov’s rho coefficients, Pearson product-moment correlations, measurement models, structural models, and goodness-of-fit statistics were used to analyse the data. The results indicate that PE fit has a positive relationship with job satisfaction. Job satisfaction has a negative relationship with intentions to leave. PE fit has an indirect effect on intentions to leave via job satisfaction. Leader empowering behaviour moderates the relationship between job satisfaction and intentions to leave. Various recommendations were made for the selected retail company as well as for future research. The retail company and employees should comprehend the impact of PE fit on outcomes such as job satisfaction and intentions to leave, as both parties are equally affected by its implications. Therefore, both pro-active and re-active measures should be institutionalised to address PE fit. Additionally, the retail company should understand the importance of leader empowering behaviour and the impact it can have on their business unit and the organisation as a whole. Recommendations for future research include longitudinal research designs, as well as the expansion of research beyond the selected company in the retail industry. / MCom (Industrial Psychology)--North-West University, Vaal Triangle Campus, 2015

Background: Health care professionals are at risk of developing burnout due to the inherently stressful nature of their work. Burnout has been found to compromise the wellbeing of health care professionals and their ability to provide optimal patient care. Job engagement is proposed to be the antipode of burnout and is concerned with occupational well-being. It is hoped that through a better understanding of factors related to job engagement and burnout, occupational well-being of health care professionals and their ability to care for patients can be improved. Systematic review: A systematic review of the literature on burnout and job engagement in physicians and nurses since 2002 identified seven studies. Findings suggest that burnout and job engagement are independent constructs, albeit negatively related. These findings contribute to the current knowledge about the relationships between burnout and engagement dimensions and provide a framework for interventions aimed at increasing occupational well-being among front line medical professionals. Aims: A study was conducted to assess levels of job engagement and burnout and their relationship with turnover intentions and job satisfaction and stress in the entire workforce of a Cancer Centre in the United Kingdom. Participants and procedure: 150 cancer care workers completed a cross-sectional questionnaire entailing the Maslach Burnout Inventory, the Engagement Indicator, measures of job satisfaction, stress, turnover intentions and demographics. Results: Mean scores of emotional exhaustion did not differ from normative data, while lower levels of depersonalisation and lack of accomplishment were found. Furthermore, engagement scores were significantly higher than in the normative sample and the majority reported high levels of job satisfaction and indicated no turnover intentions. Path analysis provided preliminary support for an exploratory model indicating that engagement mediates the relationship between job stress, burnout and job satisfaction and turnover intentions. Implications: It is important that, despite increasing pressure to reduce costs, service planning is mindful of the continuous and long-term process required to maintain and facilitate engagement and job satisfaction, which appear important to the long term retention of staff. Conclusions: Work overload and a perception of being poorly managed and resourced appear to be risk factors for burnout. However, engaged employees with high levels of personal accomplishment may experience job satisfaction and desire to stay in their jobs despite high levels of occupational stress. Further research is required to identify factors predictive of personal accomplishment and job engagement in oncology services.

The purpose of this study is to examine post-purchase evaluation factors influencing repurchase intention of credence products, and develop a model of consumer’s post-purchase evaluation for the repurchase intentions. The credence products in this case are dietary supplements, with a focus on consumers in Thailand. The study classifies a conceptual model and hypothesised relationships into two consumer perspectives: product; and brand. This research assumes that trust, expectations, satisfaction factors may relate to repurchase intention for the consumer product perspective. Also, brand trust, brand experience, expectation, and satisfaction factors are correlated with repurchase intention from the consumer brand perspective. The research adopts a hypothetico-deductive method to enable the testing of hypotheses and also a structural equation modelling (SEM) to measure the constructive relationship and regression analysis that evaluates the relationship between independent and dependent variables. Both simple regression and hierarchical multiple regression analysis were used to examine the effect of post-purchase evaluation factors on repurchase intention. These analyses are based on a sample of 504 dietary supplement users of vitamins, minerals, and herbs or other botanical products in four regions of Thailand through face-to-face structured interviews. Findings indicate that from consumers’ product perspective, consumer trust has no significant direct effect on consumer repurchase intentions whereas the relationship between consumer trust and consumer repurchase intentions of credence products are related, when it is mediated by consumer expectation and consumer satisfaction. In terms of consumers’ brand perspective, the study leads to a better understanding of consumer brand trust and consumer expectation, both of which have no significant direct effect on consumer repurchase intentions. Consumer brand trust, consumer brand experience and consumer repurchase intentions are not correlated when mediated by consumer expectation. Other findings reveal that brand experience has a direct impact on repurchase intentions whereas consumer satisfaction is a significant mediating factor when connected with: (1) the relationship between consumer brand trust and repurchase intention; (2) the relationship between consumer brand experience and repurchase intention. The study makes a contribution to a post-purchase evaluation for repurchase intentions of credence products from both consumers’ product and brand perspectives in Thailand. This study also suggests that consumer brand experience is the strongest factor and consumer satisfaction is the strongest mediator for consumers’ P-PE for the repurchase intention of credence products. From a managerial perspective, the findings of this study provide evidence for both the public and private sector in Thailand in terms of devising marketing strategies in accordance with this model.

En France, l'éducation à la biodiversité est devenue une priorité au regard de la dégradation de la diversité biologique. À l'école primaire, elle est rattachée à la fois aux disciplines scientifiques et au développement durable. Les apprentissages attendus suivent essentiellement deux dimensions : les savoirs bioécologiques et les comportements escomptés reliés à ces savoirs. Cependant, de nombreuses recherches font apparaître l'importance de la dimension affective dans ces apprentissages notamment au regard du rapport émotionnel entretenu avec les objets d'étude. Dans ce contexte, cette thèse explore les dimensions cognitive, affective et comportementale des apprentissages en éducation à la biodiversité. Le champ de recherche est restreint à l'étude d'arthropodes à l'école primaire. Quels sont les apprentissages d'élèves du primaire en éducation à la biodiversité dans le cas de l'étude d'arthropodes, selon la description, l'analyse et l'articulation de trois dimensions : savoir, affectivité et comportements ? Pour répondre à cette question, le cadre conceptuel s'appuie sur l'analyse des savoirs, sur le modèle de la maturité affective vis-à-vis des objets étudiés et sur l'opérationnalisation des comportements par les prises de position et intentions d'agir. Quatre objectifs sont poursuivis pour répondre à cette question : a) décrire et analyser chacune des trois dimensions, b) dégager les corrélations éventuelles entre les trois dimensions, c) identifier des profils particuliers d'apprenants, d) vérifier les effets d'une étude des arthropodes sur les apprentissages selon ces trois dimensions. La méthodologie utilisée suit deux perspectives : quantitative par une analyse multivariée des réponses à un questionnaire et qualitative par une analyse de réponses à la suite d'entretiens semi-dirigés. Les résultats obtenus ont permis de clarifier les trois dimensions considérées et d'éclairer leur articulation. La mesure et l'analyse de chaque dimension ont montré des différences significatives en fonction du type d'enseignement reçu en classe. Entre les dimensions analysées il existe des corrélations remarquables entre les savoirs, la maturité affective et les comportements. Des profils particuliers d'apprenants interreliant savoirs et affectivité ont pu être identifiés, ainsi que des profils généraux impliquant les trois dimensions. Nous avons pu constater l'importance de la relation affective avec les objets d'apprentissage qui, loin de perturber l'appropriation des savoirs aurait au contraire tendance à les renforcer tout en contribuant à construire des comportements citoyens et responsables.

The rate of adoption of renewable energy (RE) production and associated enterprises onfarms in the UK has been lower than expected suggesting that the UK government’s energy, agricultural and climate change objectives may not be achieved. The aim of this research is to investigate why this is the case by assessing the uptake, motivations, constraints and the factors affecting farmers’ RE investment intentions. Building on extant research literature (institutional theory, social cognition theory, theory of planned behaviour and the resource based view) a novel comprehensive and multidimensional model of entrepreneurial intentions was developed and tested using principal component, path and multivariate regression analysis techniques. Data were collected to test the model through a sample of 2000 farmers in the West Midlands Region of the UK. Of the 393 farmers who responded, 14% adopted RE enterprises, with half of adopters reporting slight to significant improvements in farm business performance in 2009. Solar panels were the most popular of the RE technologies available to farmers, compared to biomass related technologies. The study found that the most influential personal level factors contributing to the adoption of RE and associated technologies were cognitive such as the level of education. Of current 338 non-adopters, 66% might decide to invest in RE technologies over the next five years. For these potential adopters, the study shows that the type of tenure, educational attainment and the type of farm business diversification activity in which a farmer is engaged are the most significant personal and farm business situational factors which influence farmers’ RE investment intentions though contrary to expectation current non-adopters assessed the policy support framework more favourably than current adopters. The explanation of this seems to be connected with timing, in that two very positive and encouraging signals in relation to ii Feed in Tariffs (2010) and the Renewable Heat Incentive (2011) were underway or near introduction before this research took place. The study provides the first empirical evidence of the effects of the multidimensional measures of the country’s institutional profile on farmers’ RE investment intentions. Secondly, it clarifies the distinct role played by national formal and informal institutions on farmers’ investment intentions showing that informal institutions and not formal regulatory factors have a direct effect on farmers’ intentions to invest in RE enterprises. Thirdly, the investigation reveals that social acceptability of entrepreneurship in the RE sector is negatively related to investment intentions and moderates the efficacy of formal government policies in influencing entrepreneurial behaviour in the RE sector. The study concludes that any study that relies only on one type of institution will be making significant prediction mistakes. This study provides further support for cognitive based process models of intentions by showing strong significant positive effects of perceived self-efficacy and perceived desirability of RE enterprises on investment intentions. In fact, the study shows that farmers’ attitudes towards RE explain the highest amount of variance in investment intentions over and above the combined effect of external resource and institutional factors. The study illustrates that perceived self-efficacy and perceived desirability of RE enterprises mediate the effect of the rich set of exogenous variables investigated in this study on investment intentions and argues that policy makers need to focus on improving the regulatory, cognitive and normative institutional environments as a way to improve attitudes towards RE and consequently their intentions to invest in these enterprises.

Implementation intentions have been shown to improve prospective memory performance among a variety of populations. In two studies, the effectiveness of implementation intentions was examined among young and older adults. In Experiment 1 64 young adults were placed into one of four instructional conditions (Read-Only, Imagery, Implementation Intention, Combined) before completing a laboratory-based prospective memory task. Results reveal that prospective memory performance improves under each of the three experimental conditions, but that there is no additional benefit of combining imagery with implementation intentions. In a novel finding, imagery alone produced improvements comparable to implementation intentions. Experiment 2 investigated the effect of implementation intentions among 32 older adults, who were characterized as possessing high- or low-frontal function based on neuropsychological test performance. Implementation intentions improved prospective memory among both groups, regardless of frontal function. The results of these studies suggest that implementation intentions can improve prospective memory among both young and older adults. Importantly, these findings reveal that imagery alone may be an effective means of improving prospective memory. Additionally, that implementation intentions improved prospective memory among older adults, regardless of frontal function, raises important questions about potential mechanisms underlying the effectiveness of implementation intentions.

This research is a study of purchasing intentions and behaviors in China. Consumers from four key cities including Beijing, Shanghai, Chongqing, and Guangzhou were studied and differences in intentions and behavior as well as influences on behavior were analyzed. The results of the study provide greater depth to understanding consumer behavior in China and insight into likely responses to marketing strategies. Interviews with Chinese marketing experts were conducted and surveys were administered to samples of the target populations. Interviews assisted in understanding many of the general stereotypes held with respect to various ethnicities and helped with explaining some of the reasons for differences found. The study’s results are categorized into five areas. First, with respect to general purchasing intentions the study found that Chinese consumers from key cities differ significantly with respect to most of the purchasing intentions measured including inclination to try to new products, brand loyalty, use of discount cards, and willingness to purchase substitute brands. Based on five measures of conservatism, Beijing and Shanghai consumers were found to exhibit more conservative consumption behaviors than Chongqing and Guangzhou consumers. Chongqing and Guangzhou consumers are more likely than consumers in Shanghai and Beijing to wait for a friend's recommendation before buying a new brand. Second, with respect to brand choices, the study found that Beijing consumers tend to be more ethnocentric in their purchasing behavior in comparison to consumers from other key cities. The study also found a moderate association between ethnicity and brand purchase repertoire in most product categories. Third, with respect to reasons for purchases, the study found that generally there was only limited association between ethnicity and the reason for selecting brands. Consumers most often cited quality as the main reason for purchase. Fourth, with respect to actual brand purchase frequencies, the study found that Beijing consumers made more frequent purchases more often than other consumers in half of the categories studied. Chongqing consumers tend to purchase favorite brands less frequently than consumers from other key cities. Fifth, with respect to knowledge of country of origin and country of manufacture and their influences on intentions, the study found that for most product categories (nine of twelve studied) country of origin was an important consideration in the purchase decision. In general, many Chinese consumers are misinformed about brands’ country of origin. The research provides insight into important purchase cues and moderators impacting brand choice behavior.

Each year approximately 90,000 new cases of cancer are diagnosed in people of working age in the United Kingdom (UK) (Morrell & Pryce, 2005). The potential impact of cancer and its treatment on working life is substantial, with approximately 40% of all cancer patients taking time off work during treatment and recovery (Short, Vasey & Tunceli, 2005). However, little information is available on employment outcomes for those managing colorectal cancer. Colorectal cancer is a commonly diagnosed cancer with approximately 36,000 people diagnosed each year in the UK. Although research demonstrates promising return to work outcomes for this group, not enough is known about the factors (variables) impacting their return to work intentions, work ability and employment outcomes. The aims of this research were to: examine the return to work intentions, work ability and employment outcomes of colorectal cancer patients over six months; explore the role of self-efficacy and psychosocial well-being, and explore the role of health professionals in providing work-related support and information to patients. Findings from these studies may help to better inform future interventions to support this cancer group. Fifty participants newly diagnosed with colorectal cancer were recruited from three Acute NHS Trusts (n = 27) across the Midlands and a support group (n = 23) affiliated to a National Cancer Charity. Participants completed questionnaires at three time points: baseline (post surgery or pre-treatment); follow-up time 1 (3 months), and follow-up time 2 (6 months). As well as illness and demographic characteristics, the questionnaires measured job self-efficacy, work ability, cancer self-efficacy, quality of life, fatigue and depression. A sub-sample of participants (n = 10) completed a monthly diary over six months. This captured temporal fluctuations and patterns in cancer management, return to work intentions and work ability and the factors impacting upon these (self-efficacy and social support). Finally, 18 health professionals participated in semi-structured interviews that explored the nature and type of work-related advice currently provided to colorectal cancer patients. Data were analysed using both quantitative (ANOVAs and regression) and qualitative techniques (thematic analysis). The questionnaire study identified varying levels in self-assessed work ability and psychosocial well-being. Most importantly, positive changes in perceptions of cancer self-efficacy F (1.02, 61.12) = 14.70, p = 0.0005, and job self-efficacy F (2, 94) = 10.85, p = 0.0005 were detected over time; however, interactions between treatment type and time did not emerge (p > 0.05). Factors related to perceived work ability outcomes cross-sectionally included type of occupation (β = 0.31, t = 2.65, p = 0.0005) and quality of life (β = 0.42, t = 2.57, p = 0.01) at baseline, treatment type (β = -0.19, t = -1.94, p = 0.05) at follow-up time 1 and job self-efficacy at follow-up time 1 (β = 0.57, t = 4.40, p = 0.0005) and time 2 (β = 0.50, t = 2.92, p = 0.006). In contrast, factors related to employment status (i.e. working, not working) were job self-efficacy (OR = 2.20, 95% CI: 1.17 4.13) at baseline and occupation (OR = 0.03, 95% CI: 0.00 0.86), and perceived work ability (OR = 3.05, 95% CI: 1.00 12.80) at follow-up time 2. Along with self-assessed work ability at baseline (β = 0.67, t = 3.99, p = 0.0005), receiving chemotherapy alone or a combination of treatments (i.e. other than surgery alone) (β = -0.24, t = -1.99, p = 0.05) were the strongest predictors of follow-up work ability (independent of age and occupation). Finally, treatment type (OR = 9.91, 95% CI: 1.57 62.50) was also identified as the strongest predictor of employment status approximately six months after diagnosis. Findings from the diary study suggest that self-efficacy beliefs were important in understanding employment outcomes and return to work intentions. The role of such beliefs was multi-faceted and results infer that several factors seemed to impact return to work intentions and self-efficacy temporally. Treatment, symptoms and decrements in perceived work ability were identified as the most prominent factors that served as barriers preventing resumption of work. Moreover, there was a degree of disparity between return to work intent and work ability. Additionally, the diary study identified variation in work-related advice and guidance provided to colorectal patients. Subsequently, some participants may have been under the impression that they were unable to work, especially during treatment. Results from the interview study found that health professionals attempted to provide guidance to working-aged patients. However, the nature of such guidance varied due to experience, knowledge and time constraints. Furthermore, participants highlighted a lack of knowledge and an insufficient evidence base were barriers to providing more appropriate guidance. The majority of participants stated that this was an aspect of patient care that falls short and to address the issue a concerted multi-disciplinary effort was required. In short, the findings indicate that the factors related to work ability, return to work intentions and employment outcomes of colorectal cancer patients varied over time, whereby certain variables took precedence over others at particular time points. Furthermore, the results suggest that self-efficacy beliefs are important; however, it is crucial to point out that self-efficacy is unlikely to operate as a stand-alone factor. Indeed, it is argued that it may be a construct that is considered in future research endeavours alongside pre-existing findings, which would inevitably help towards gaining a more comprehensive account of the factors related to the work outcomes of individuals affected by cancer.

Agent-based models (ABM) are an increasingly important research tool for describing and predicting interactions among humans and their environment. A key challenge for such models is the ability to faithfully represent human decision making with respect to observed behaviour. This thesis aims to address this challenge by developing a methodology for empirical measurement and simulation of decision making in humanenvironment systems. The methodology employs the Beliefs-Desires-Intentions (BDI) model of human reasoning to directly translate empirically measured decision data into artificial agents, based on sound theoretical principles. A common simulated decision environment is used for both eliciting human decision making behaviour, and validating artificial agents. Using this approach facilitates the collection of decision making narratives by way of participatory simulation, and promotes a fair comparison of real and modelled decision making. The methodology is applied in two case studies: One to carry out a trial involving human subjects solving an abstract land-use problem, and another to examine the feasibility of up-scaling the methodology to a real agricultural scenario—dairy farming. Results from the experiments indicate that the BDI-based methodology achieved reasonably direct encoding of decision making behaviour from elicited human narratives. The main limitations found with the technique are: (1) the significant use of subjects’ time required to elicit their decision making behaviour; (2) the significant programming effort required; and (3) the challenge of aggregating behaviour from multiple subjects into a generalised decision making model. In spite of its limitations, BDI has shown its strengths as a tool for empirical analysis and simulation of decision making in research of human-environment systems.

Background: Alcohol has become ubiquitous in Swedish lifestyle blogs, as alcohol can be present in one third or one fifth of blog posts in some of Sweden’s biggest lifestyle blogs. Research suggests that exposure to media and commercial communications on alcohol increases consumption and that users and user-generated content related to alcohol and drinking may intensify social norms around alcohol consumption. This means Swedish lifestyle bloggers may be exposing alcohol and creating social normative influence that can affect blog readers’ intention to consume alcohol. Purpose: The purpose of this thesis was to explore if and how the presence of alcoholic beverages on Swedish blogs may affect young females’ intention to pursue alcohol consumption. Firstly, the study looks at to what extent and how alcoholic beverages and alcohol-related activities appear on Swedish lifestyle blogs. Secondly, the study explores if the presence of alcohol in blogs is recognised by blog readers and if they perceive this to affect their own and others' intention to consume alcohol. Method: This thesis has two different data collections to fulfil the purpose of the study. First a web content analysis is conducted on eight Swedish blogs to explore the presence of alcohol. Thereafter semi-structured interviews are conducted with nine respondents. The findings are compared to previous findings and analysed from theories on behavioural change. Conclusion: Alcohol and alcohol-related activities are depicted frequently in some of Sweden’s biggest lifestyle blogs when variation between blogs and monthly variance per blog are considered. Alcohol is put in a favourable setting through a positive or a commercial context. Blog readers perceive blog posts to contain positive alcohol content, and claim others may be affected to consume alcohol by these as bloggers have influence empowered by their social status. A majority of respondents claim they themselves are not affected by blog posts with alcohol. It is suggested this is because subjective attitude towards alcohol and a belief of personal control has stronger impact on intention to pursue alcohol-related activities. Another suggestion is that more salient and ready accessible referents such as parents, family and friends are deemed more important in affecting norms around alcohol through individuals’ perceived view of these referents’ desires and actions.
