Breaking ranks: the emergence of representative associations in the Irish armed forces 1989-1992

This study contexualises the relationship between the armed forces and the civil authority in Ireland using and revising the theoretical framework advanced by Huntington. It tracks the evolution of the idea of a representive body for soldiers in the late 1980s, to the setting up of statutory associations under the Defence Amendment Act 1990. The study considers Irish soldiers political agitation and their use of peaceful democratic activities to achieve their aims. It highlights the fundamental policy arguments that were made against the idea of representation for the army and positions those arguments in the study of civil-military relations. Utilising unique access to secret Department of Defence files, it reveals in-depth ideological arguments advanced by the military authories in Ireland against independent representation. This thesis provides an academic study of the establishment of PDFORRA. It answers key questions regarding the change in the position of Irish government who were categorically opposed to the idea of representation in the army. It illustrates the involvement of other agencies such as the European Organisation of Military Associations (Euromil) reveals reciprocal support by the Irish associations to other emerging groups in Spain. Accessing as yet unpublished Department of Defence files, study analyses tension between the military authorities and the government. It highlights for the first time the role of enlisted personnel in the shaping of new state structures and successfully dismmisses Huntingtons theoretical contention that enlisted personnel are of no consequence in the study of civil-military relations. It fills a gap in our understanding, identified by Finer, as to how politicisation of soldiers takes place. This thesis brings a new dimension to the discipline of civil-military relations and creates new knowledge that will enhance our understanding of an area not covered previously.

Hazard and early warning analysis based on domain specific modeling technologies

An aim of proactive risk management strategies is the timely identification of safety related risks. One way to achieve this is by deploying early warning systems. Early warning systems aim to provide useful information on the presence of potential threats to the system, the level of vulnerability of a system, or both of these, in a timely manner. This information can then be used to take proactive safety measures. The United Nation’s has recommended that any early warning system need to have four essential elements, which are the risk knowledge element, a monitoring and warning service, dissemination and communication and a response capability. This research deals with the risk knowledge element of an early warning system. The risk knowledge element of an early warning system contains models of possible accident scenarios. These accident scenarios are created by using hazard analysis techniques, which are categorised as traditional and contemporary. The assumption in traditional hazard analysis techniques is that accidents are occurred due to a sequence of events, whereas, the assumption of contemporary hazard analysis techniques is that safety is an emergent property of complex systems. The problem is that there is no availability of a software editor which can be used by analysts to create models of accident scenarios based on contemporary hazard analysis techniques and generate computer code that represent the models at the same time. This research aims to enhance the process of generating computer code based on graphical models that associate early warning signs and causal factors to a hazard, based on contemporary hazard analyses techniques. For this purpose, the thesis investigates the use of Domain Specific Modeling (DSM) technologies. The contributions of this thesis is the design and development of a set of three graphical Domain Specific Modeling languages (DSML)s, that when combined together, provide all of the necessary constructs that will enable safety experts and practitioners to conduct hazard and early warning analysis based on a contemporary hazard analysis approach. The languages represent those elements and relations necessary to define accident scenarios and their associated early warning signs. The three DSMLs were incorporated in to a prototype software editor that enables safety scientists and practitioners to create and edit hazard and early warning analysis models in a usable manner and as a result to generate executable code automatically. This research proves that the DSM technologies can be used to develop a set of three DSMLs which can allow user to conduct hazard and early warning analysis in more usable manner. Furthermore, the three DSMLs and their dedicated editor, which are presented in this thesis, may provide a significant enhancement to the process of creating the risk knowledge element of computer based early warning systems.

A post-structuralist analysis of Irish youth crime prevention policy with specific emphasis on the Garda youth diversion projects

Garda Youth Diversion Projects (GYDPs) have since their beginnings in the early 1990s gained an increasingly important role and now constitute a central feature of Irish youth justice provision. Managed by the Irish Youth Justice Service and implemented by the Gardai and a variety of youth work organisations as well as independent community organisations, GYDPs are located at the crossroads of welfarist and corporatist approaches to youth justice, combining diversionary and preventative aspects in their work. To date, these projects have been subjected to very little systematic analysis and they have thus largely escaped critical scrutiny. To address this gap, this thesis locates the analysis of GYDP policy and practice within a post-structuralist theoretical framework and deploys discourse analysis primarily based on the work of Michel Foucault. It makes visible the official youth crime prevention and GYDP policy discourses and identifies how official discourses relating to youth crime prevention, young people and their offending behaviour, are drawn upon, negotiated, rejected or re-contextualised by project workers and JLOs. It also lays bare how project workers and JLOs draw upon a variety of other discourses, resulting in multi-layered, complex and sometimes contradictory constructions of young people, their offending behaviour and corresponding interventions. At a time when the projects are undergoing significant changes in terms of their repositioning to operate as the support infrastructure underpinning the statutory Garda Youth Diversion Programme, the thesis traces the discursive shifts and the implications for practice that are occurring as the projects move away from a youth work orientation towards a youth justice orientation. A key contribution of this thesis is the insight it provides into how young people and their families are being constituted in individualising and sometimes pathologising ways in GYDP discourses and practices. It reveals the part played by the GYDP intervention in favouring individual and narrow familial causes of offending behaviour while broader societal contexts are sidelined. By explicating the very assumptions upon which contemporary youth crime prevention policy, as well as GYDP policy and practice are based, this thesis offers a counterpoint to the prevailing evidence-based agenda of much research in the field of Irish youth justice theory and youth studies more generally. Rather, it encourages the reader to take a step back and examine some of the most fundamental and unquestioned assumptions about the construction of young people, their offending behaviour and ways of addressing this, in contemporary Irish youth crime prevention policy and practice.

Cereal products for specific dietary requirements. Evaluation and improvement of technological and nutritional properties of gluten free raw materials and end products

Coeliac disease is one of the most common food intolerances worldwide and at present the gluten free diet remains the only suitable treatment. A market overview conducted as part of this thesis on nutritional and sensory quality of commercially available gluten free breads and pasta showed that improvements are necessary. Many products show strong off-flavors, poor mouthfeel and reduced shelf-life. Since the life-long avoidance of the cereal protein gluten means a major change to the diet, it is important to also consider the nutritional value of products intending to replace staple foods such as bread or pasta. This thesis addresses this issue by characterising available gluten free cereal and pseudocereal flours to facilitate a better raw material choice. It was observed that especially quinoa, buckwheat and teff are high in essential nutrients, such as protein, minerals and folate. In addition the potential of functional ingredients such as inulin, β-glucan, HPMC and xanthan to improve loaf quality were evaluated. Results show that these ingredients can increase loaf volume and reduce crumb hardness as well as rate of staling but that the effect diverges strongly depending on the bread formulation used. Furthermore, fresh egg pasta formulations based on teff and oat flour were developed. The resulting products were characterised regarding sensory and textural properties as well as in vitro digestibility. Scanning electron and confocal laser scanning microscopy was used throughout the thesis to visualise structural changes occurring during baking and pasta making

The expression and regulation of pregnancy-specific glycoproteins in the mouse

Pregnancy-Specific Glycoproteins (PSG) are the most abundant fetally expressed proteins in the maternal bloodstream at term. This multigene family are immunoglobulin superfamily members and are predominantly expressed in the syncytiotrophoblast of human placenta and in giant cells and spongiotrophoblast of rodent placenta. PSGs are encoded by seventeen genes in the mouse and ten genes in the human. Little is known about the function of this gene family, although they have been implicated in immune modulation and angiogenesis through the induction of cytokines such as IL-10 and TGFβ1 in monocytes, and more recently, have been shown to inhibit the platelet-fibrinogen interaction. I provide new information concerning the evolution of the murine Psg genomic locus structure and organisation, through the discovery of a recent gene inversion event of Psg22 within the major murine Psg cluster. In addition to this, I have performed an examination of the expression patterns of individual Psg genes in placental and non-placental tissues. This study centres on Psg22, which is the most abundant murine Psg transcript detected in the first half of pregnancy. A novel alternative splice variant transcript of Psg22 lacking the protein N1-domain was discovered, and similar to the full length isoform induces TGFβ1 in macrophage and monocytic cell lines. The identification of a bidirectional antisense long non-coding RNA transcript directly adjacent to Psg22 and its associated active local chromatin conformation, suggests an interesting epigenetic gene-specific regulatory mechanism that may be responsible for the high level of Psg22 expression relative to the other Psg family members upon trophoblast giant cell differentiation

Pregnancy-specific glycoprotein function, conservation and receptor investigation

Pregnancy-specific glycoproteins (PSGs) are highly glycosylated secreted proteins encoded by multi-gene families in some placental mammals. They are carcinoembryonic antigen (CEA) family and immunoglobulin (Ig) superfamily members. PSGs are immunomodulatory, and have been demonstrated to possess antiplatelet and pro-angiogenic properties. Low serum levels of these proteins have been correlated with adverse pregnancy outcomes. Objectives: Main research goals of this thesis were: 1). To attempt to replicate previously reported cytokine responses to PSG-treatment of immune cells and subsequently to investigate functionally important amino acids within PSG1. 2). To determine whether candidate receptor, integrin αvβ3, was a binding partner for PSG1 and to investigate whether PSG1 possessed functionality in a leukocyte-endothelial interaction assay. 3). To determine whether proteins generated from recently identified putative PSG genes in the horse shared functional properties with PSGs from other species. Outcomes: 1). Sequential domain deletion of PSG1 as well as mutation of conserved residues within the PSG1 Ndomain did not affect PSG1-induced TGF-β1. The investigated response was subsequently found to be the result of latent TGF-β1 contaminating the recombinant protein. Protein further purified by SEC to remove this showed no induction of TGF-β1. The most N-terminal glycosylation site was demonstrated to have an important role in PSG N domain secretion. PSG1 attenuated LPS-induced IL-6 and TNF-α. Investigations into signalling underpinning this proved inconclusive. 2). Integrin αvβ3 was identified as a novel PSG1 receptor mediating an as yet unknown function. Preliminary investigations into a role for PSGs as inhibitors of leukocyte endothelial interactions showed no effect by PSG1. 3). Horse PSG protein, CEACAM49, was shown to be similarly contaminated by latent TGF-β1 particle and once removed did not demonstrate TGF-β1 release. Interestingly horse PSG did show anti-platelet properties through inhibition of the plateletfibrinogen interaction as previously published for mouse and human PSGs.

Preclinical atherosclerosis in rheumatoid arthritis

Introduction: There is accumulating evidence of an increased risk of cardiovascular morbidity and mortality in rheumatoid arthritis patients. A combination of both traditional cardiovascular risks and rheumatoid specific factors appear to be responsible for driving this phenomenon. Rheumatoid arthritis has been an orphan of cardiologists in the past and rheumatologists themselves are not good at CVD screening. Identifying the extent of preclinical atherosclerosis in RA patients will help us to appreciate the magnitude of this serious problem in an Irish population. Methods: We undertook a cross-sectional study of 63 RA patients and 48 OA controls and compared the 2 groups with respect to 1) traditional CV risks factors, 2) serum biomarkers of inflammation, including CRP, TNFα, IL6 and PAI-1, 3) carotid intima-media thickness (cIMT), carotid plaque and ankle-brachial index (ABI) as markers of pre-clinical atherosclerosis, 4) biochemical and ultrasonic measures of endothelial dysfunction and 5) serum and echocardiographic measures of diastolic dysfunction. Within the RA group, we also investigated for associations between markers of inflammation, subclinical atherosclerosis and diastolic dysfunction. Results: Prevalence of traditional CV risks was similar in the RA and OA groups. A number of biomarkers of inflammation were significantly higher in the RA group: CRP, fibrinogen, IL- 2, -4, -6, TNFα. PAI-1, a marker of thrombosis, correlated with disease activity and subclinical atherosclerosis in RA patients. With regard to subclinical atherosclerosis measures, RA patients had a significantly lower ABI than OA patients. Carotid plaque and cIMT readings were similar in RA and OA patients. Assessment of endothelial function revealed that RA patients had significantly higher concentrations of adhesion molecules, in particular sero-positive RA patients and RA smokers. Adhesion molecule concentrations were associated with markers of diastolic dysfunction in RA. Urine PCR, another marker of endothelial dysfunction also correlated with diastolic dysfunction in RA. Assessment of endothelial function with flow mediated dilatation (FMD) found no difference between the RA and OA groups. Disease activity scores in RA patients were associated with endothelial dysfunction, as assessed by FMD. Conclusions: We did not find significant differences in measures of subclinical atherosclerosis, flow mediated dilatation or diastolic function between RA and OA patients. This is most likely in part due to the fact that there is increasing evidence that OA has an inflammatory component to its pathogenesis and is associated with metabolic syndrome and increased CV risk. We reported a significant association between urinary PCR and measures of diastolic dysfunction. Urinary PCR may be a useful screening tool for diastolic dysfunction in RA. The association between RA disease activity and measures of vascular function supports the theory that the excess cardiovascular burden in RA is linked to uncontrolled inflammation.

A cultural study on communication and technology with specific reference to media in China

This dissertation examines the role of communications technology in social change. It examines secondary data on contemporary China arguing that many interpretations of events in China are unsuitable at best and at worst conceptually damages our understanding of social change in China. This is especially the case in media studies under the ‘democratic framework’. It proposes that there is an alternative framework in studying the media and social change. This alternative conceptual framework is termed a zone of interpretative development offering a means by which to discuss events that take place in a mediated environment. Taking a theoretical foundation using the philosophy of Mikhail Bakhtin this dissertation develops a platform with which to understand communication technology from an anthropological perspective. Three media events from contemporary China are examined. The first examines the Democracy Wall event and the implications of using a public sphere framework. The second case examines the phenomenon of the Grass Mud Horse, a symbol that has gained popular purchase as a humorous expression of political dissatisfaction and develops the problems seen in the first case but with some solutions. Using a modification of Lev Vygotskiĭ’s zone of proximal development this symbol is understood as an expression of the collective recognition of a shared experience. In the second example from the popular TV talent show contests in China further expressions of collective experience are introduced. With the evidence from these media events in contemporary China this dissertation proposes that we can understand certain modes of communication as occurring in a zone of interpretative development. This proposed anthropological feature of social change via communication and technology can fruitfully describe meaning-formation in society via the expression and recognition of shared experiences.
