Most research on Cognitive Load Theory (Sweller, 1988) has uncovered many instructional design considerations for learning complex tasks. Additionally, the Community of Inquiry (Garrison, Anderson, & Archer, 2000) framework describes many of the learning experiences in online education. A gap existed in the literature for investigating cognitive load over the duration of a college algebra course and for investigating the relationship between cognitive load and cognitive presence. This research study has addressed this gap by investigating cognitive load and cognitive presence in an online and face-to-face college algebra course. The results of this study revealed that face-to-face students earned statistically significant higher final course grades and homework grades than the online students. The face-to-face math course was slightly more efficient because it produced learners who exerted similar cognitive load as learners in the online course but the learners in the face-to-face earned higher performance score. Online discussion prompts that ask student to apply their solution or defend their solution engaged students in cognitive presence differently. When students were prompted to apply their solution to a real world scenario, most students reached resolution in their initial posts, but they were often not cognitively present in their follow-up posts. When students were prompted to provide a defense of their solution, most of the posts demonstrated cognitive presence, but not as many individual students reached resolution. Additionally, students progressed through the stages of cognitive presence when an instructor asked them a specific question about their math problem or real life scenario in a timely manner. When instructors post questions to their students that directly ask for an application of their hypothesis or an explanation how they arrived at their hypothesis, students can reach the highest stage of cognitive presence. When instructors post messages that reach the highest stage of cognitive presence, students do not post messages that reach the highest stage of cognitive presence. Lastly, this study did not find a strong linear relationship between cognitive presence and cognitive load.

Digital inequalities continue to concern researchers across highly technologised countries. In recent years, however, most research on digital inequalities has focused on distinguishing different patterns of Internet use rather than examining Internet non-users. The few quantitative studies of non-use and reasons for non-use often stay on a descriptive level, while qualitative studies mostly investigate subpopulations, such as those living in specific neighbourhoods. Although there are a number of studies of digital inequalities among young people and the elderly, a systematic literature search finds no research focusing on middle-aged individuals, who might face specific problems with being offline, as they are of working age and more likely than other age groups to have children living in the household. On the basis of a mixed-methods research design that compares non-users in Great Britain and Sweden, the overarching research question for this study sheds light on the mechanisms contributing to Internet non-use, as it examines the socio-economic backgrounds, attitudes, perceptions, and everyday life experiences of non-users with a focus on 25 to 55 year-olds. It applies advanced statistical analyses of secondary nationally representative survey data as well as in-depth analysis of qualitative interviews with 10 middle-aged non-users from each country. The analysis of these combined data shows that while socio-economic variables still play an important role in influencing who is on- and offline, general attitudes towards technologies are even more influential. The study finds that there is a lack of life-fit (Selwyn 2006) of ICTs for a number of non-users and a potentially negative impact of warm experts (Bakardjeva 2005) who have previously been regarded as a positive influence. Moreover, vulnerable groups (e.g. immigrants) are facing more substantial problems, such as issues with literacy and language, which need to be tackled first. The deliberation of similarities and differences between Britain and Sweden against the backdrop of policy interventions and cultural values shows that being offline is not problematic for all Internet non-users; some of them thrive in highly technologised societies. The conclusion offers proposals for both future research and policy interventions for those, currently offline mainly due to socio-economic reasons, who would like to go online in the future.

This thesis is concerned with student understanding of key concepts in electrical engineering teaching within higher education. Anecdotal evidence suggests that many students struggle to understand threshold concepts and therefore encounter difficulties in learning theoretical models which are underpinned by such theoretical concepts. This research utilised a mixed methods approach to investigate the factors that influence student understanding of key theoretical concepts within electrical engineering. The initial study used a questionnaire to evaluate student understanding of concepts which were identified by teaching staff as being core to a particular module. The study identified that students commenced the module with poor understanding and that instruction on the module ELC040 Electrical Machines and Systems did not lead to improved understanding of core concepts. This suggests that the roots of student misunderstanding lay elsewhere. Desk research was subsequently employed to explore the sources of student misunderstandings. Performance data was analysed and demonstrated that the roots of the student misunderstanding of Electrical Machine Theory lay in the pre-requisite module Electrical Power B. Students routinely failed to achieve high levels of understanding in this module and as a result were unable to successfully build upon it in the third year module. Semi-structured interviews were then undertaken with Part C students who were undertaking the Electrical Machines and Systems module. In addition, structured interviews were administered with the Part B students. The interviews aimed to establish the study practices adopted by students across both years. The study showed that students found the ELA001 module difficult, and the majority believe that most other students felt the same way as they did. Students provided evidence of poor study techniques, by reporting last minute sessions to complete coursework and last minute revision for exams. This research informed the development of an interactive learning tool which was piloted on a small cohort of students. The research has also established that there are many influences on the development of student understanding of threshold concepts within electrical engineering and argues for a more active style of teaching in order to address student misunderstanding.

Violence is a leading cause of morbidity and mortality amongst young people. Public health approaches are now being increasingly utilised to reduce the risk of young peoples' involvement in violence. One such programme is Medics Against Violence (MAV), which aims to reduce pro-violent attitudes and enhance empathy in secondary school pupils. This thesis aims to investigate whether this approach can be effective in tackling youth violence in secondary school pupils. A mixed-methods approach was adopted to conduct both an outcome and process evaluation of MAV. Four schools took part in the outcome evaluation, which examined whether there was a change in attitudes towards violence or empathy in pupils receiving the MAV programme. The process evaluation consisted of focus groups with school pupils, and open-ended questionnaires and semi-structured interviews with MAV volunteers. There was a small but significant reduction in pro-violent attitudes immediately post-intervention. However, this was not sustained at three months and there was no significant increase in empathy scores. Pupils generally demonstrated anti-violent attitudes, although were more likely to support the use of reactive violence. The pupils appeared to enjoy and generally engage well with the programme. In particular, the use of real footage, interviews with those affected by violence and the Glasgow setting provided a sense of realism for the pupils. Moreover, pupils valued the opportunity to discuss the issues raised by MAV with the volunteers. Volunteers felt engagement was occasionally an issue in the most affluent areas. However, some volunteers adapted the programme to focus on victimisation prevention in the most affluent schools. Further development is therefore needed in terms of establishing who the programme is aimed at (i.e. potential victims or perpetrators), focusing on reactive violence and increasing the sustainability of its effects.

The communication of anthropogenic climate change presents many challenges, for communicators, scientists, policymakers and publics alike. Particularly difficult is the issue of uncertainty, which can include ambiguity around the phenomenon of climate change, the possible impacts of this, and the timeframe within which such impacts will be seen. Previous research has established that audiences are often averse to uncertainty, and will disregard or ignore messages that contain it. This raises a theoretical and practical question of how best to manage uncertainty in climate change communication in order to maintain audience engagement. This question was the focus of this PhD research. Specifically, the aim of this thesis was to explore the process of climate change communication from the perspectives of the scientists, communicators, and the recipient. I achieved this research goal by utilising a mixed methods design. I firstly interviewed the originators (i.e., scientists) and professional communicators of climate change information to explore the process from their side (Chapter 2). This revealed a number of themes connecting to the different ways scientists and communicators understand the process of communication (e.g., as information exchange versus relationship building), the challenges of climate change communication and uncertainty in particular, and the (appropriate) role of scientists when communicating with the public about climate change. Next, in a series of studies I experimentally explored how audiences respond to variations in the informational content of climate change messages (such as the level of uncertainty) and the role of different communicative styles in further shaping audience engagement (Chapter 3). Broadly, the results of these studies suggest that while uncertainty can undermine audience engagement with climate change communications, the negative effects of uncertainty are buffered when the communicator is perceived to be high in morality and/ or when they use an open communication style. Interestingly, these effects of communication style were particularly evident among women, whereas men tended to react against this. Together, these studies show how relational factors (e.g., communication styles and perceptions of communication sources) can moderate the impact of informational content on audience responses. Finally, I ended this programme of research by looking in more detail at how audiences perceive a real scientific organisation engaged in climate change communication and the bases of their beliefs about organisation competence and morality (Chapter 4). This study combined qualitative and quantitative data to delve deeper into some of the insights gained in the experimental work, and to reconnect this to the real-world organisation context I began with. This study again showed how perceptions of communicator morality moderate responses to uncertainty, but also provide useful insights into the different origins of perceptions of morality and competence. Chapter 5 concludes by summarising the research presented in this thesis, discussing its strengths, limitations and ways forward. Here, I also consider the theoretical, methodological and practical implications of the thesis’ research findings. Briefly, it is argued that addressing the scientific uncertainties of climate change may not necessarily mean altering the form of information itself. Rather, modifying the language peripheral to the information that contains uncertainty, attending to the ways in which audiences perceive the sources of uncertainty, and considering variations amongst publics, may help to engage in effective communication around the complex issue of climate change.

As businesses are becoming increasingly aware of their ever changing market environments; constraints and opportunities arise which result in organisations evolving and re-structuring accordingly. Therefore, their organisational spaces are evolving to follow suit. A theoretical shift has occurred in OT, from considerations of space as an 'organisation' to 'organising' viewing space as processual which involves an understanding of space as something which is continually produced and re-produced through social relations (Dale & Burrell, 2008). While in the past organisational space often referred to the interior space of an organisation, consideration of recent literature demonstrates that organisational space is not limited to the internal, but also includes the external space of an organisational building. The key points of the literature review are centred on the users in the space, as well as the materialisation of power through spatial design and space as an experience. A mixed-method approach of observation, interviews and a questionnaire are used to understand the Forum user; defined here as a form of multi-locational worker. The case study approach on the Forum Building at the University of Exeter is used to position a typology of University open workspaces in the wider context of open, public and communal [OPC] workspaces, with the intention of generating research directions that extend current theory. Key results of this study are the 'unspoken reciprocity' among Forum users and the importance of 'visuality'; the act of seeing while being seen, in motivating individuals. Furthermore, the spatial elements of 'flexible accessibility', 'flexible workspaces' and active atmosphere are major contributors to making the Forum space an attractive workspace in the current University trend of 'interdisciplinary spaces' (Coulson et al., 2014; Temple, 2014). This thesis makes both a theoretical and methodological contribution to the organisational studies literature through the holistic case study approach to viewing organisational spaces. Through a socio-spatial perspective of multi-locational users' perceptions of their changing everyday working environment, the research provides significant insight into the conceptualisation, design, operations and management of such spaces.

Secularisation is at the centre of a vibrant debate in the sociology of religion. In the last two decades, literature has started to challenge old predictions and interpretations of the future of religion, but few studies present a detailed contextual examination of religious change in contemporary societies. Offering a comparative analysis of Scotland and Sweden, two nations in the relatively secularised Northern Europe, this thesis argues that diverse historical and political trajectories shape distinct patterns of religious beliefs and practices. Scotland and Sweden are two secularising nations characterised by historically dominant Protestant churches, but which nonetheless differ largely in their experiences of religious decline. In order to discern and differentiate key aspects of religious change in each nation as well as to explore contextual meanings of religion, a mixed methods approach was adopted, comprised of secondary quantitative data analysis as well as in-depth interviews. Data analysis identified and highlighted broader patterns and individual understandings of religious beliefs as well as three dimensions of religious belonging: church attendance, religious identification and membership, and participation in rituals. Results show that on measures of religious beliefs and church attendance, Sweden appears further secularised than Scotland. Arguably, Sweden has seen rapid and relatively early secularisation, with important social structural and political changes that occurred in the second half of the 19th century. With noticeable generational differences, data on Scotland point towards the mid-20th century as a crucial time of religious decline. Additionally, the remaining functions of the national churches differ considerably in the two nations. A majority of Swedes identify with the Church of Sweden, which serves a largely secular purpose as part of a cultural heritage and as a provider of life cycle ceremonies. By contrast, the Church of Scotland has maintained a stronger commitment to religious doctrine in a nation that is more religiously diverse. The findings ultimately draw attention to the importance of context in the study of diverse and complex processes of religious change. As a result, they reveal limitations to attempts in the contemporary sociology of religion set out to generalise and dichotomise European trends of religious belief and belonging.

Existing commonly used maternal-fetal attachment instruments have not been thoroughly tested for reliability and validity; criticism can be levelled for a variety of problems ranging from lack of reliability due to an inadequate underpinning framework to facilitate objective interpretation to limited generalizability due to the sample. The aim of this study is to acknowledge the centrality of the mother, to use the experiences of pregnant women to generate a definition of maternalfetal attachment and ultimately create a tool that will act as a reliable, valid and simple measurement. A mixed method framework utilising a sequential exploratory strategy has allowed qualitative exploration of the phenomenon under investigation followed by quantitative testing of the emerging theory on a much larger and different sample. Phase 1 involved face to face open structured interviews on an opportunity sample of 10 (5 primigravid; 5 multiparous) women in the final trimester of pregnancy followed by 3 focus groups targeting specific groups – primigravid women (6 participants); multiparous women (7 participants) and teenagers (4 participants). Data analysis was through constant comparative methodology. A multidimensional, psycho-biological definition of attachment was generated from the women’s own perception of their attachment to their fetus. This was used as a framework to design a questionnaire for the measurement of maternal-fetal attachment. Phase 2 involved the validation of the questionnaire and further testing of the definition. Cohort 1 tested for reliability with 200 participants within their second or third trimester of pregnancy. Following modification of the questionnaire, Cohort 2 a sample of 150 women within the final trimester of pregnancy tested the tool for internal reliability and validity. The generated Maternal-Fetal Attachment Tool (MFAT) following rigorous testing proved both reliable and valid. Maternal fetal attachment is founded in psycho-biological theory and is a complex multi-dimensional construct. Central to the definition is the woman’s need to protect her fetus, attachment develops as the fetus becomes more tangible, it is facilitated through the woman’s intergenerational experience of attachment and through appropriate social support. Maternal-fetal attachment facilitates behavioural change to ensure a favourable intra-uterine environment.

The purpose of this embedded quasi-experimental mixed methods research was to use solving simple linear equations as the lens for looking at the effectiveness of concrete and virtual manipulatives as compared to a control group using learning methods without manipulatives. Further, the researcher wanted to investigate unique benefits and drawbacks associated with each manipulative. Qualitative research methods such as observation, teacher interviews, and student focus group interviews were employed. Quantitative data analysis techniques were used to analyze pretest and posttest data of middle school students (n=76). ANCOVA, analysis of covariance, uncovered statistically significant differences in favor of the control group. Differences in posttest scores, triangulated with qualitative data, suggested that concrete and virtual manipulatives require more classroom time because of administrative issues and because of time needed to learn how to operate the manipulative in addition to necessary time to learn mathematics content. Teachers must allow students enough time to develop conceptual understanding linking the manipulatives to the mathematics represented. Additionally, a discussion of unique benefits and drawbacks of each manipulative sheds light on the use of manipulatives in middle school mathematics.

Using quantitative and qualitative data analytic techniques, the present study explores the parent-adolescent relationship from a pilot study of 15 triads (overall N = 45). First, the statistical relationship between positive relational affect and electrical brain activity was assessed during parent-adolescent conflict communication (N = 30). Specifically, using electroencephalography (EEG) technology, electrical brain activity was recorded during family problem-solving discussions between a mother, father, and adolescent child. Observational coding was used to determine participant and triad positive affect ratios (PARs). Principles of positive-to-negative affect were incorporated into an affective neuroscience framework and used as the theoretical basis for the quantitative portion of this research. Findings suggest that in relation to positive affect, hemispheric lateralization occurs during parent-adolescent problem-solving discussions. Second, the behavioral-family systems model of parent-adolescent conflict (Robin & Foster, 1989) was used to theoretically undergird the qualitative portion of the study. Based on this theoretical model, a thematic content analysis was conducted using transcripts from the triadic problem-solving discussions (N = 45). Patterns of parent-adolescent communication were assessed, and a modified grounded theory approach was applied to emergent communication themes that differed from those presented in the theory. Similarities and differences in conflict communication behaviors and positive affect ratios were compared between families. Contextual descriptions of each family are offered.
