Blood donor motivation and recruitment : a comparative study in West of Scotland and the Sudan

In modern society, blood donor motivation and recruitment is a fundamental part of health care delivery. Well defined and documented programmes exist throughout the world but new ideas are always welcome. The situation in the Sudan is different and much remains to be done by way of comparison with elsewhere. This thesis outlines the objectives of a study, how it was supported, sponsored and achieved. It describes briefly the geography of the Sudan, the source of Sudanese economy, climate, culture and historical backgrounds. The problems of existing services in the Sudan are reviewed and a brief account of the demographic characteristics of the Sudanese population is given. Two surveys done in West of Scotland and in the Sudan are described in detail. This work discloses and compares the positive motives that enhances giving of blood and the negative motives that hinders its donation. The comparison is between an Eastern Society with a voluntary motivation not fully activated because of lack of understanding and awareness of the need to give blood voluntarily for strangers and Western Society with a well established voluntary system of donation. An addition to this research was the investigation into the immunity to tetanus and hepatitis in the Sudanese population. An estimate of the percentage of individuals with detectable levels of hepatitis A and B antibodies and tetanus antibodies is included since there is a need to establish a plasmapheresis programme as part of a good Blood Transfusion Service for the procurement of specific immunoglobulin's. This work has revealed major differences between the West of Scotland and the Sudan and suggestions are made for their resolution. The main conclusion and comparison are summarised in Chapter 7. It is hoped that many of the suggestions in this thesis can be introduced in the Sudan at an early date.

Film policy in practice: a case study of Scottish Screen’s funding schemes

This thesis examines cultural policy for film in Scotland, from 1997 to 2010. It explores the extent to which the industry is shaped by film policy strategies and through the agency of public funding bodies. It reflects on how Scottish Screen, Scotland’s former screen agency, articulated its role as a national institution concerned with both commercial and cultural remits, with the conflicting interests of different industry groups. The study examines how the agency developed funding schemes to fulfil policy directives during a tumultuous period in Scottish cultural policy history, following the establishment of the Scottish Parliament with the Scotland Act 1998 and preceding the Independence Referendum Act 2013. In order to investigate how policy has shaped the development of a national film industry, a further two case studies are explored. These are Tartan Shorts, Scotland’s former flagship short film scheme, and the Audience Development Fund, Scotland’s first project based film exhibition scheme. The first study explores the planning, implementation and evaluation of the scheme as part of the agency’s talent development strategy. The outcomes of this study show the potential impact of funding methods aimed at developing and retaining Scottish filmmaking talent. Thereafter, the Scottish exhibition sector is discussed; a formerly unexplored field within film policy discussions and academic debate. It outlines Scottish Screen’s legacy to current film exhibition funding practices and the practical mechanisms the agency utilised to foster Scottish audiences. By mapping the historical and political terrain, the research analyses the specificity of Scotland within the UK context and explores areas in which short-term, context-driven policies become problematic. The work concludes by presenting the advantages and issues caused by film funding practices, advocating what is needed for the film industry in Scotland today with suggestions for long-term and cohesive policy development.

Re-imagining the theology of human sexuality in the Methodist Church: the use of narrative in theological methodology

This thesis proposes the development of a narrative methodology in the British Methodist Church. Such a methodology embraces and communicates both felt experience and critical theological thinking, thus producing and presenting a theology that might have a constructive transformative impact on wider society. In chapter one I explore the ways in which the Church speaks in public, identify some of the challenges it faces, and consider four models of engagement. If the Church is to engage in public discourses then I argue that its words need to be relevant and connect with people’s experiences. To ground the thinking I focus on the context of the British Methodist Church and explore how the Church engages in theological reflection through the lens of its thinking on issues of human sexuality. Chapter two reviews how theological reflection is undertaken in the British Methodist Church. I describe how the Methodist Quadrilateral of Scripture, tradition, reason and experience remains a foundational framework for theological reflection within the Methodist Church and consider the impact of institutional processes and the ways in which the Methodist people actually engage with theological thinking. The third and fourth chapters focus on how the British Methodist Church has produced its theology of human sexuality, giving particular attention to the use of personal and sexual stories in this process. I find that whilst there has been a desire to listen to the stories of the Methodist people, there has not been a corresponding interrogation or analysis of their stories so as to enable robust and constructive theological reflection on these experiences. Using resources from Foucauldian approaches to discourse analysis, I critique key statements and the processes involved in their production, offering an analysis of this body of theological thinking and indicating where possibilities for alternative ways of thinking and acting arise. The proposed methodology draws upon resources from social science methodologies, and in chapter five I look at the use of personal experience and relevant strategies of inquiry that prompt reflection on the hermeneutical process and employ narrative approaches in undertaking, analysing and presenting research. The exploration shows that qualitative research methodologies offer resources and methods of inquiry that could help the Church to engage with personal stories in its theological thinking in a robust, interrogative and imaginative way. In chapter six an examination of story and narrative is undertaken, to show how they have been understood as ways of knowing and how they relate to theological inquiry. Whilst acknowledging some of the limitations of narrative, I indicate how it offers constructive possibilities for theological reflection and could be a means for the British Methodist Church to engage in public discourse. This is explored further in chapter seven, which looks in more detail at how the British Methodist Church has used narrative in its theological thinking, and outlines areas requiring further attention in order for a narrative theological methodology to be developed, namely: attention to the question ‘whose experience?’; investigation of issues of power and the dynamics involved in the process of the production of theological thought; how personal stories and experiences are interrogated and how narrative is constructed; and how narrative might be employed within the Methodist Quadrilateral. The final chapter considers the advantages and limitations of such an approach, whether the development of such a method is possible in the Methodist Church today and its potential for helping the Church to engage in public discourse more effectively. I argue that this methodology can provoke new theological insights and enable new ways of being in the world

Controlled surface nanotopography and oxygen plasma treatment of PEEK to improve cellular response

Poly(aryl-ether-ether-ketone) (PEEK) is a semi crystalline polymer which exhibits properties that make it an attractive choice for use as an implant material. It displays natural radiolucency, and MRI compatibility, as well as good chemical and sterilization resistance, both of which make it of particular interest in orthopaedic implants. However, PEEK has demonstrated poor cellular adhesion both in vitro and in vivo. This is problematic as implant surfaces that do not develop a layer of adhesive cells are at risk of undergoing fibrous encapsulation, which in turn leads to lack of a strong interface between the implant device and the patient tissue, which can in turn lead to failure of the implant and revision surgery . As incorporating nanotopography into a polymer surface has been demonstrated to be able to direct the differentiation behaviour of stem cells, a possible solution to PEEKs underlying issues with poor cellular response would be to incorporate specific nanoscale topography into the material surface through injection moulding, and then analysing if this is a viable method for addressing PEEKs issues with cellular response. In addition to nanoscale topography, the experimental PEEK surfaces were treated with oxygen plasma to address the underlying cytophobicity of the material. As this type of treatment has been documented to be capable of etching the PEEK surface, experiments were carried out to quantify the effect of this treatment, both on the ability of cells to adhere to the PEEK surface, as well as the effect it has upon the nanotopography present at the PEEK surface. The results demonstrated that there were a range of plasma treatments which would significantly improve the ability of cells to adhere to the PEEK surface without causing unacceptable damage to the nanotopography. Three different types of cells with osteogenic capacity were tested with the PEEK surfaces to gauge the ability of the topography to alter their behaviour: SAOS-2, osteoprogenitors and 271+ MSCs. Due to PEEKs material properties (it is non transparent, exhibits birefringence and is strongly autofluorescent) a number of histological techniques were used to investigate a number of different stages that take place in osteogenesis. The different cell types did display slightly different responses to the topographies. The SAOS-2 cells cultured on surfaces that had been plasma treated for 2 minutes at 200W had statistically significantly higher levels of von Kossa staining on the NSQ surface compared to the planar surface, and the same experiment employing alizarin red staining, showed a statistically significantly lower level of staining on the SQ surface compared to the planar surface. Using primary osteoprogenitor cells designed to look into if whether or not the presence of nanotopography effected the osteogenic response of these cells, we saw a lack of statistically significant difference produced by the surfaces investigated. By utilising HRP based immunostaining, we were able to investigate, in a quantitative fashion, the production of the two osteogenic markers osteopontin and osteocalcin by cells. When stained for osteocalcin, the SQ nanotopography had total percentage of the surface with stained material, average area and average perimeter all statistically significantly lower than the planar surface. For the cells that were stained for osteopontin, the SQ nanotopgraphy had a total percentage of the surface with stained material, average area and average perimeter all highly statistically significantly lower than those of the planar surface. Additionally, for this marker the NSQ nanotopography had average areas and average perimeters that were highly significantly higher than those of the planar surface. There were no significant differences for any of the values investigated for the 271+ MSC’s When plasma treatment was varied, the SAOS-2 cells demonstrated an overall trend i.e. increasing the energy of plasma treatment in turn leads to an increase in the overall percentage of staining. A similar experiment employing stem cells isolated from human bone marrow instead of SAOS-2 cells showed that for polycarbonate surfaces , used as a control, mineralization is statistically significantly higher on the NSQ nanopattern compared to the planar surface, whereas on the PEEK surfaces we observe the opposite trend i.e. the NSQ nanotopography having a statistically significantly lower amount of mineralization compared to the planar surface at the 200W 2min and 30W 1min plasma treatments. The standout trend from the PEEK results in this experiment was that the statistically significant differences on the PEEK substrates were clustered around the lower energy plasma treatments, which could suggest that the plasma treatment disrupted a function of the nanotopograhy which is why, as the energy increases, there are less statistically significant differences between the NSQ nanotopography and the Planar surface This thesis documents the response of a number of different types of cells to specific nanoscale topographies incorporated into the PEEK surface which had been treated with oxygen plasma. It outlines the development of a number of histological methods which measure different aspects of osteogenesis, and were selected to both work with PEEK, and produce quantitative results through the use of Cell Profiler. The methods that have been employed in this body of work would be of interest to other researchers working with this material, as well as those working with similarly autofluorescent materials.
