The 21st century has seen a dramatic rise in Internet access and connectivity across the world. To date, only a small amount of research has been published on the subject of culture and Internet usage. This thesis investigates whether, and how, individuals from two different cultures (Saudi Arabia and the UK) engage with online social networks (OSNs) differently, and what might be the underlying psychological factors explaining such differences. A first qualitative study used interpretative phenomenological analysis (IPA; Smith, Flowers, & Larkin, 2009) to investigate motivations for using OSNs among Saudi and British participants. Both groups reported that they used OSNs to present a positive self-image, while desiring to maintain a sense of their ‘genuine' self in online interactions. For Saudi participants, OSNs also provided opportunities for selfexpression that were otherwise unavailable. British participants reported using OSNs for relationship maintenance. A second qualitative study also looked at motivations, but narrowed the focus to identity motives, applying motivated identity construction theory (Vignoles, 2011) to a thematic analysis of tweets written by citizens of Saudi Arabia and the United Kingdom. Motives for meaning, belonging, distinctiveness, continuity, efficacy, and self-esteem were all detectable in the tweets of both Saudi and British users. The manner in which these motives were pursued varied according to the cultural context of users within the affordances of the online context in which they were communicating. The research project then aimed to establish a way of measuring differences in online self-presentation strategies, by developing the online self-presentation strategies scale (OSPSS). Items were selected using exploratory structural equation modelling (ESEM). The scale was incorporated in a large-scale (N = 694) quantitative study of Saudi and British OSN users that measured self-presentation strategies, motivations of OSNs use and target audience. Mediation analyses were conducted to find out whether cultural differences in these dimensions were explained by two forms of cultural variation: relational mobility and Schwartz' theory of basic values. Self-enhancement vs. self-transcendence values and relational mobility, more than openness to change vs. conservation values, accounted for mean differences between the groups in motives, targeted audiences and self-presentation strategies. Together the studies reveal observable differences in the ways in which people from Saudi Arabia and the UK engage with OSNs. These are partially explained by the affordances that social media provide, which compensate for the unavailability of certain modes of expression and communication within offline cultural contexts, and by cultural differences in value priorities.

This thesis is the first study of the crowd psychology of the annual Hajj, or pilgrimage to Mecca (Makkah) in Saudi Arabia, to employ self-categorization theory (SCT). The thesis aims to document and understand the perspective of pilgrims from a social psychological point of view, since no one has done that before, as well as to understand the perceptions of the Hajj management. Specifically, the thesis focuses on crowd perceptions, feelings of safety and the reasons for these feelings, and relations between subgroups in the crowd and between pilgrims and management. A literature review in Chapter two highlights the history and culture of the Hajj and the issues in managing the Hajj. Academic perspectives on crowd psychology are discussed in chapter three. Chapters four and five present respectively a UK pilot study of pilgrims and a field pilot study of pilgrims and management. Chapter six (the main interview study with pilgrims) indicates that despite the inconveniences, participants felt safe, secure and wellbeing inside the Grand Mosque during Hajj. Chapter seven (the main interview study with Hajj management) explores the participants' understanding of crowd behaviour, crowd psychology and its relation to safety, danger and their own role. In Chapter eight (the major study of the thesis), a survey of 1194 pilgrims at the Hajj found that identification with the crowd predicted enjoyment of the crowd. Also, for those high in identification with the crowd, crowd density increased perceptions of safety. Perceived support was found to mediate these positive effects of social identity on feeling safe. Chapter nine critically explores the findings of the thesis and discusses them in relation to relevant literature. It also reflects on the implications of the study for the theory of crowd psychology, and considers what lessons there might be for the management of the Hajj. This chapter concludes the thesis and outlines suggestions for further research.

Planning for incidents involving mass decontamination has focused almost exclusively on technical aspects of decontamination, with little attempt to understand public experiences and behaviour. This thesis aimed to examine relevant theory and research, in order to understand public behaviour during incidents involving mass decontamination, and to develop theoretically-derived recommendations for emergency responders. As these incidents involve groups, it was expected that social identity processes would play an important role in public responses. A review of small-scale incidents involving decontamination is presented, along with a review of decontamination guidance documents for emergency responders. This literature shows that responder communication strategies play an important role in public experiences and behaviour, but that the importance of communication is not reflected in guidance documents. Theories of mass emergency behaviour, in particular the social identity approach, are reviewed, in order to generate hypotheses and recommendations for the management of incidents involving mass decontamination. It is hypothesised that effective responder communication will increase public compliance and cooperation, and reduce anxiety, mediated by social identity variables (e.g. perceptions of responder legitimacy, identification with emergency responders and other members of public, and collective agency). The empirical research presented in this thesis tests the hypotheses and recommendations derived from the social identity approach. The research includes: a responder interview study; three studies of volunteer feedback from field exercises; a visualisation experiment; and a mass decontamination field experiment. Findings show that effective responder communication consistently results in increased willingness to comply with decontamination, and increased public cooperation; this relationship is mediated by social identity variables. Results support the hypotheses, and show that an understanding of the social identity approach facilitates the development of effective responder communication strategies for incidents involving mass decontamination. Four theoretically-derived, and evidence-based, recommendations for emergency responders are generated as a result of this thesis.

This research investigated the causes of behavioural difficulties among family businessers in two studies. Study one adapted the evolutionary theory of the firm to the family business context in an empirical study that involved 370 family businessers from 46 families. The study found that: (1) stakeholder cohorts within the family (employed by the business versus not employed by the business; owners of stock versus non stock owners; related to founder versus not related; male versus female) were significantly divided on business direction and planning, the introduction of new routines to the business and various roles, habits, norms and codes that made up the collective knowledge base of the firm; (2) the founding generation reported significantly higher levels of individualism and self-belief than second and third generation family businessers; and (3) the founding generation differed significantly to the third (but not the second) generation on business direction and planning related matters.The second study was a single case design study involving two second-generation family businessers and one third-generation family businesser from three separate family businesses. Using the Skinnerian theory-based technique of functional assessment and the recently formulated Valued Outcomes Analysis (VOA) each individual’s behaviour was analyzed after an initial interview. From this analysis, causes of behaviour were derived and presented to each participant with suggestions for behaviour change. As a result of adopting the suggestions, each individual reported improved functioning at a second interview conducted after a five-week lapse. It was found that individual functioning in family business could be improved by establishing (1) the function of the behaviour, and (2) the valued outcomes that drive the behaviour. The findings of the two studies are linked, limitations of the research are addressed and future projects discussed.

Abstract / Multinational corporations have played a significant role for e-learning systems’ penetration in Africa. This study sought to explore how e-learning systems are accepted and used by a multinational corporation in Africa. The multinational company focuses in building materials and construction. The qualitative research approach utilizing the exploratory and analytical case study design was employed in this study. The research participants comprised of managers who are employees of a multinational corporation, and they were purposively sampled from Middle East Africa region. Research instruments used were interviews guide and questionnaires on e-learning and its use by a multinational corporation operating in Africa. The results revealed that e-learning systems play a pivotal role in transforming education in Africa. The study also found that for a prosperous e-learning strategy in Africa, there is requisite for leadership transformation, team building, and easy access to information. In addition, there is also a need for commercial transformation, and understanding of company goals, induction of new members, and promotion of a learning culture, collaboration, and guidance. Finally, the study considered the various e-learning systems application challenges in Africa. These were found to range from the lack of technological awareness by learners, lack of time by the working class, poor connectivity, high setup costs, language barriers, as well as the lack of customised gadgets for e-learning. / School of Computing / M.Sc.

Das Thema dieser Dissertation ist die Anwendung des „Matching Law” als Verhaltensannahme bei der Erklärung sozialer Phänomene. Das „Matching Law” ist ein Modell der behavioristischen Lerntheorie und sagt aus, dass die relative Häufigkeit der Wahl einer Handlung mit der relativen Häufigkeit der Belohnung dieser Handlung übereinstimmt. In der Dissertation werden verschiedene Probleme in Bezug auf die soziologische Anwendung des „Matching Law” erörtert. Aufbauend auf diesen Erkenntnissen wird das Entsprechungsgesetz in die ökonomische Entscheidungstheorie integriert und mit bestehenden Verhaltensprognosen theoretisch verglichen. Anschließend wird das Entsprechungsgesetz auf mehrere soziale Situationen angewandt. Dabei kommt ein Lernmodell zum Einsatz, welches als „Melioration Learning” bezeichnet wird und unter bestimmten Bedingungen zum Entsprechungsgesetz führt. Mit Hilfe dieses Lernmodells und agentenbasierter Simulationen werden Hypothesen zu sozialem Verhalten hergeleitet. Zunächst werden einfache Situationen mit nur zwei interagierenden Akteuren betrachtet. Dabei lassen sich durch das Entsprechungsgesetz einige Lösungskonzepte der Spieltheorie replizieren, obwohl weniger Annahmen bezüglich der kognitiven Fähigkeiten der Akteure und der verfügbaren Informationen gesetzt werden. Außerdem werden Interaktionen zwischen beliebig vielen Akteuren untersucht. Erstens lässt sich die Entstehung sozialer Konventionen über das Entsprechungsgesetz erklären. Zweitens wird dargestellt, dass die Akteure lernen, in einem Freiwilligendilemma oder einem Mehrpersonen-Gefangenendilemma zu kooperieren.

The epistemological problem of unity and its development in the philosophy of Bertrand Russell is the main subject of this essay. The first chapter is devoted to naïve realism developed by G. E. Moore and adopted by early Russell. I explain the notion of objective unity of proposition. The second chapter concerns Russell's departure from naïve realism and the multiple relation of judgment which Wittgenstein's criticism rendered as fatally unable to handle the problem of synthetic unity. The breakdown of this theory led Russell to naturalism, which is the topic of the last chapter. I pay special attention to the regressive argument proposed in slightly different versions by Moore, L. Wittgenstein and G. Ryle. Keywords realism, neutral monism, behaviorism, unity, consciousness

Excessive alcohol consumption among UK university students is well documented. Although alcohol use reduces over the time spent at university, drinking patterns of undergraduates have been associated with risk of alcohol dependence and abuse a decade following graduation. Consequently, UK universities should endeavour to promote responsible drinking among their drinking student population. This thesis presents four studies that aim to inform the development of feasible and effective alcohol-related interventions targeting the student population. The first two studies examined the effect of an alcohol-related outcome expectancy manipulation on alcohol-related cognitions and consumption. Study one showed that a manipulation aiming to bolster negative expectancies and contradict positive expectancies was associated with immediate reductions in mild desires for alcohol. Study two provided limited support for study one, and indicated that repeated exposure to the manipulation was not associated with significantly greater effects. Neither study showed significant reductions in alcohol consumption. Study three used a survey to examine the predictive utility of a broader range of correlates of alcohol consumption, and provided an integrative model of risky drinking behaviour. The model highlighted the importance of age when first regularly drinking, the sensation-seeking personality trait, social drinking motives, confidence in ability to drink within government guidelines, and the perceived quantity and frequency of alcohol consumed by university friends. Study four consisted of a systematic review and meta-analysis examining the effectiveness of computer-delivered interventions (CDIs) across different study design features and identified the characteristics of CDIs associated with the largest effects. CDI efficacy was greater for primary than secondary outcomes, and varied according to the control condition and outcomes used. CDIs with the largest effects utilised personalised normative feedback among US heavy/binge drinking students. The results of these studies contribute to the current intervention literature and can be used to inform intervention development in UK universities.

This dissertation is about perceptions of non-drinkers and the social experiences of university students who do not drink alcohol. Chapter One provides a comprehensive literature review. Chapter Two outlines relevant methodological issues. Chapter Three reports findings from a cross-sectional study. Alcohol prototype measures were used to compute a sociability prototype differences variable (i.e., sociability prototypes for regular drinkers minus sociability prototypes for non-drinkers), which was associated with student drinking. Chapter Four reports a moderating effect of sociability prototype differences: beliefs about high levels of peer drinking were associated with less health-adherent drinking intention among students with less favourable evaluations of non-drinkers. Quantitative findings are summarised in Chapter Five. Chapters Six and Seven present findings from an interpretative phenomenological analysis of interviews with non-drinkers. Chapter Six suggests different strategies involved in non-drinking during social occasions, while Chapter Seven describes how authenticity is involved in deciding not to drink and within conversations about non-drinking. Chapters Eight and Nine summarise qualitative study findings and outline an intervention study, respectively. Chapter Ten reports intervention study findings. Students were asked to imagine possible benefits or anticipated strategic requirements engaged in safer drinking behaviour at four week follow-up compared with students who completed a drinks diary. Chapter Eleven summarises findings, discusses applied and theoretical implications, acknowledges programme limitations and proposes research extensions.
