Performance, transmission and devotion: understanding the Anglo-Saxon prayer books, c.800-1050

Through an investigation of the Anglo-Saxon prayer books and selected psalters, this thesis corrects standard histories of medieval devotion that circumvent the Anglo-Saxon contribution to medieval piety. In the first half of the thesis, I establish a theoretical framework for Anglo-Saxon piety in which to explore the prayers. Current theoretical frameworks dealing with the medieval devotional material are flawed as scholars use terms such as ‘affective piety’, ‘private’ and even ‘devotion’ vaguely. After an introduction which defines some of the core terminology, Chapter 2 introduces the principal witnesses to the Anglo-Saxon prayer tradition. These include the prodigal eighth- and early ninth- century Mercian Group, comprising the Book of Nunnaminster (London, British Library, Harley 2965, s. viii ex/ix1), the Harleian Prayer Book (London, British Library, Harley 7653, s. viii ex/ix1), the Royal Prayer Book (London, British Library, Royal 2 A. xx, s. viii2/ix1/4), and the Book of Cerne (Cambridge, University Library, Ll. 1. 10). These prayer books are the earliest of their kind in Europe. This chapter challenges some established views concerning the prayer books, including purported Irish influence on their composition and the probability of female ownership. Chapter 3 explores the performance of prayer. The chapter demonstrates that Anglo-Saxon prayers, for example, the Royal Abecedarian Prayer, were transmitted fluidly. The complex relationship between this abecedarian prayer and its reflex in the Book of Nunnaminster reveals the complexity of prayer composition and transmission in the early medieval world but more importantly, it helps scholars theorise how the prayers may have been used, whether recited verbatim or used for extemporalisation. Changes made by later readers to earlier texts are also vital to this study, since they help answer questions of usage and show the evolution and subsequent influence of Anglo-Saxon religiosity. The second half of the thesis makes a special study of prayers to the Cross, the wounded Christ, and the Virgin, three important themes in later medieval spirituality. These focus on the Royal Abecedarian Prayer, which explores Christ’s life (Chapter 5), especially his Passion; the ‘Domine Ihesu Christe, adoro te cruce’ which celebrates the Cross (Chapter 4); and the Oratio Alchfriðo ad sanctam Mariam, which invokes the Virgin Mary (Chapter 6). These prayers occur in multiple, temporally-diverse witnesses and have complex transmission histories, involving both oral and written dissemination. The concluding chapter (7) highlights some of the avenues for future research opened by the thesis.

Hospital clinicians information behaviour and attitudes towards the 'Clinical Informationist': an Irish survey

Background: Hospital clinicians are increasingly expected to practice evidence-based medicine (EBM) in order to minimize medical errors and ensure quality patient care, but experience obstacles to information-seeking. The introduction of a Clinical Informationist (CI) is explored as a possible solution. Aims:  This paper investigates the self-perceived information needs, behaviour and skill levels of clinicians in two Irish public hospitals. It also explores clinicians perceptions and attitudes to the introduction of a CI into their clinical teams. Methods: A questionnaire survey approach was utilised for this study, with 22 clinicians in two hospitals. Data analysis was conducted using descriptive statistics. Results: Analysis showed that clinicians experience diverse information needs for patient care, and that barriers such as time constraints and insufficient access to resources hinder their information-seeking. Findings also showed that clinicians struggle to fit information-seeking into their working day, regularly seeking to answer patient-related queries outside of working hours. Attitudes towards the concept of a CI were predominantly positive. Conclusion: This paper highlights the factors that characterise and limit hospital clinicians information-seeking, and suggests the CI as a potentially useful addition to the clinical team, to help them to resolve their information needs for patient care.

Understanding teacher collaboration in disadvantaged urban primary schools: uncovering practices that foster professional learning communities

This study is set in the context of disadvantaged urban primary schools in Ireland. It inquires into the collaborative practices of primary teachers exploring how class teachers and support teachers develop ways of working together in an effort to improve the literacy and numeracy levels of their student. Traditionally teachers have worked in isolation and therefore ‘collaboration’ as a practice has been slow to permeate the historically embedded assumption of how a teacher should work. This study aims to answer the following questions. 1). What are the dynamics of teacher collaboration in disadvantaged urban primary schools? 2). In what ways are teacher collaboration and teacher learning related? 3). In what ways does teacher collaboration influence students’ opportunities for learning? In answering these research questions, this study aims to contribute to the body of knowledge pertaining to teacher learning through collaboration. Though current policy and literature advocate and make a case for the development of collaborative teaching practices, key studies have identified gaps in the research literature in relation to the impact of teacher collaboration in schools. This study seeks to address some of those gaps by establishing how schools develop a collaborative environment and how teaching practices are enacted in such a setting. It seeks to determine what skills, relationships, structures and conditions are most important in developing collaborative environments that foster the development of professional learning communities (PLCs). This study uses a mixed method research design involving a postal survey, four snap-shot case studies and one in depth case study in an effort to establish if collaborative practice is a feasible practice resulting in worthwhile benefits for both teachers and students.

The Irish House of Lords, 1780-1800: politics and ideology

This thesis covers the Irish House of Lords in the last two decades of its life. A number of important themes run through the work - the regency crisis, patronage, the management of the Lords, the relationship between the Lords and Commons. These themes, explored from different angles, are vital to an understanding of the political role of the upper house in the 1780s and 1790s. This study is confined to the Lords as a political institution and thus its judicial role as final court of appeal, which was restored to it in 1782, will not be explored here. The thesis consists of two parts. Part one examines the structure and powers of the House of Lords while part two looks at the parties and policies of the house. Chapter one discusses the British constitution as imposed upon Ireland. Chapter two suggests the reasons why constitutional changes were introduced in 1782, and looks at the contribution made by the Irish House of Lords in securing these changes. Chapter three explores the various channels of influence which the peers enjoyed. Chapter four explores the sometimes tense relationship between Lords and Commons. Chapter five examines management of the House of Lords by Dublin Castle. Part two, begins at chapter six. This chapter explores the leadership of both parties within the Lords. Chapter seven looks at how patronage was used to reward those who were loyal to the government. Chapter eight explores the influence of the Whig opposition. Chapter nine looks at the controversial attempts made by Pitt and his ministry during the 1790s to win the support of catholics and turn them from the lure of French ideas, and of the response of the peers to these attempts. Chapter ten is concerned with the relationship between the peers of the House of Lords and the lords lieutenant during the 1790s. Chapter eleven looks at the Union and the House of Lords and attempts to answer the question historians have long asked: why did the Irish parliament and the House of Lords in particular, look favourably on the proposed union of the two kingdoms and the end of their own institution? The House of Lords in the closing decades of the eighteenth century was an institution within which the wealth and power of the kingdom could be found. Its members were politically active, both inside and outside the house. It contained a majority who saw the Crown as the source of stability, but it was a living and evolving political organism and therefore it contained men who believed that the Crown should have its influence limited. This evolution is also demonstrated in its desire for political change in 1782 and 1788. Its last, and perhaps most radical decision, was to vote for its own demise in 1900.

Systematic delay-driven power optimisation and power-driven delay optimisation of combinational circuits

With the proliferation of mobile wireless communication and embedded systems, the energy efficiency becomes a major design constraint. The dissipated energy is often referred as the product of power dissipation and the input-output delay. Most of electronic design automation techniques focus on optimising only one of these parameters either power or delay. Industry standard design flows integrate systematic methods of optimising either area or timing while for power consumption optimisation one often employs heuristics which are characteristic to a specific design. In this work we answer three questions in our quest to provide a systematic approach to joint power and delay Optimisation. The first question of our research is: How to build a design flow which incorporates academic and industry standard design flows for power optimisation? To address this question, we use a reference design flow provided by Synopsys and integrate in this flow academic tools and methodologies. The proposed design flow is used as a platform for analysing some novel algorithms and methodologies for optimisation in the context of digital circuits. The second question we answer is: Is possible to apply a systematic approach for power optimisation in the context of combinational digital circuits? The starting point is a selection of a suitable data structure which can easily incorporate information about delay, power, area and which then allows optimisation algorithms to be applied. In particular we address the implications of a systematic power optimisation methodologies and the potential degradation of other (often conflicting) parameters such as area or the delay of implementation. Finally, the third question which this thesis attempts to answer is: Is there a systematic approach for multi-objective optimisation of delay and power? A delay-driven power and power-driven delay optimisation is proposed in order to have balanced delay and power values. This implies that each power optimisation step is not only constrained by the decrease in power but also the increase in delay. Similarly, each delay optimisation step is not only governed with the decrease in delay but also the increase in power. The goal is to obtain multi-objective optimisation of digital circuits where the two conflicting objectives are power and delay. The logic synthesis and optimisation methodology is based on AND-Inverter Graphs (AIGs) which represent the functionality of the circuit. The switching activities and arrival times of circuit nodes are annotated onto an AND-Inverter Graph under the zero and a non-zero-delay model. We introduce then several reordering rules which are applied on the AIG nodes to minimise switching power or longest path delay of the circuit at the pre-technology mapping level. The academic Electronic Design Automation (EDA) tool ABC is used for the manipulation of AND-Inverter Graphs. We have implemented various combinatorial optimisation algorithms often used in Electronic Design Automation such as Simulated Annealing and Uniform Cost Search Algorithm. Simulated Annealing (SMA) is a probabilistic meta heuristic for the global optimization problem of locating a good approximation to the global optimum of a given function in a large search space. We used SMA to probabilistically decide between moving from one optimised solution to another such that the dynamic power is optimised under given delay constraints and the delay is optimised under given power constraints. A good approximation to the global optimum solution of energy constraint is obtained. Uniform Cost Search (UCS) is a tree search algorithm used for traversing or searching a weighted tree, tree structure, or graph. We have used Uniform Cost Search Algorithm to search within the AIG network, a specific AIG node order for the reordering rules application. After the reordering rules application, the AIG network is mapped to an AIG netlist using specific library cells. Our approach combines network re-structuring, AIG nodes reordering, dynamic power and longest path delay estimation and optimisation and finally technology mapping to an AIG netlist. A set of MCNC Benchmark circuits and large combinational circuits up to 100,000 gates have been used to validate our methodology. Comparisons for power and delay optimisation are made with the best synthesis scripts used in ABC. Reduction of 23% in power and 15% in delay with minimal overhead is achieved, compared to the best known ABC results. Also, our approach is also implemented on a number of processors with combinational and sequential components and significant savings are achieved.

Max Stirner's relevance to contemporary philosophy: a critical analysis

The aim of this dissertation is to revive the 19th-century thinker Max Stirner’s thought through a critical reexamination of his mistaken legacy as a ‘political’ thinker. The reading of Stirner that I present is one of an ontological thinker, spurred on as much—if not more—by the contents of Hegel’s Phenomenology of Spirit as it is the radical roots that Hegel unintentionally planted. In the first chapter, the role of language in Stirner’s thought is examined, and the problems to which his conception of language seem to give rise are addressed. The second chapter looks at Stirner’s purportedly ‘anarchistic’ politics and finds the ‘anarchist’ reading of Stirner misguided. Rather than being a ‘political’ anarchist, it is argued that we ought to understand Stirner as advocating a sort of ‘ontological’ anarchism in which the very existence of authority is questioned. In the third chapter, I look at the political ramifications of Stirner’s ontology as well as the critique of liberalism contained within it, and argue that the politics implicit in his philosophy shares more in common with the tradition of political realism than it does anarchism. The fourth chapter is dedicated to an examination of Stirner’s anti-humanism, which is concluded to be much different than the ‘anti-humanisms’ associated with other, more famous thinkers, such as Foucault and Heidegger. In the fifth and final chapter, I provide an answer to the question(s) of how, if, and to what extent Friedrich Nietzsche was influenced by Stirner. It is concluded that the complete lack of evidence that Nietzsche ever read Stirner is proof enough to dismiss accusations of plagiarism on Nietzsche’s part, thus emphasizing the originality and singularity of both thinkers.

Urbanisation and sport participation in townships in China

Urbanisation as a phenomenon is a complex social process which can be quite difficult to define and understand. In recent years, urbanisation in China has developed at an ever increasing rate. Urban population rates have now surpassed 50% (figure from 2011). Based on the growing importance placed on the increasing number of urbanised/urbanising townships, the issue of people’s lives within the townships has also become an important feature in regard to the impact that urbanisation is having upon China. Clearly this links China’s urban development to the transformation of sport participation in China. This research aims to examine what the reality of the sport participation on-the-ground is within six selective townships in China and examine the reasons for the reality through the lens of figurational theory. In order to do so, some features of Norbert Elias’s figurational theory (involvement and detachment, power) are employed as the theoretical framework. Two townships in Lüliang of Shanxi province, two townships in Jincheng of Shanxi Province and two townships in Huizhou of Guangdong province were selected in order to answer these key questions. The three cities which the townships are located are in different stages of urbanisation. Semi-structured interview were conducted. The current situation were described from the aspects of age, gender, occupation and income aspects and the transformation of sport participation. This research concludes that the current sport participation situation within these six townships is due to the influences stemming from several aspects: sport policy and sport organisation; economy condition, culture, urbanisation, and self-requirement and individual interest towards sport. This power forms a network of interdependency which also aids our understanding of the current sport participation within these six selected Chinese townships.

Exploiting the bioactive potential of marine sponge microbiota

Endospore-forming bacteria are often isolated from different marine sponges, but their abundance varies, and they are frequently missed by culture-independent studies. Within endospore-formers, Bacillus are renowned for the production of antimicrobials and other compounds of medical and industrial importance. Although this group has been well studied in many different environments, very little is known about the actual diversity and properties of sporeformers associated with marine sponges. Identification of the endospore-forming bacteria associated with the marine sponges; Haliclona simulans, Amphilectus fucorum and Cliona celata, has uncovered an abundant and diverse microbial population composed of Bacillus, Paenibacillus, Solibacillus, Halobacillus and Viridibacillus species. This diversity appears to be overlooked by other non-targeted approaches where spore-formers are masked by more dominant species within the ecosystem. In addition to the identification of two antibiotic resistant plasmids, this bank of sporeformers produce a range of bioactive compounds. New antimicrobial compounds are urgently needed to combat the spread of multidrug resistant pathogens, as few new options are entering the drug discovery pipelines for clinical trials. Based on the results of this project, endospore-formers associated with marine sponges may hold the answer. The power of coupling functional based assays with genomic approaches has enabled us to identify a novel class 1 lantibiotic, subtilomycin, which is active against several clinically relevant pathogens. Subtilomycin is encoded in the genomes of all the marine sponge B. subtilis isolates analysed. They cluster together phylogenetically and form a distinct group from other sequenced B. subtilis strains. Regardless of its potential clinical relevance, subtilomycin may be providing these strains with a specific competitive advantage(s) within the stringent confines of the marine sponge environment. This work has outlined the industrial and biotechnological potential of marine sponge endospore-formers which appear to produce a cocktail of bioactive compounds. Genome sequencing of specific marine sponge isolates highlighted the importance of mining extreme environments and habitats for new lead compounds with potential therapeutic applications.

The role played by angiotensin (1-7) in the regulation of renal haemodynamics and excretory function in anesthetized rats

Initial studies have demonstrated that intra- renal infusion of Ang (1-7) caused a diuresis and natriuresis that was proportional to the degree of activation of the Renin Angiotensin Aldosterone System (RAAS). This raised the question as why the magnitude of this diuresis and natriuresis was compromised in rats receiving a high sodium diet (suppressed RAAS) and enhanced in low sodium fed rats (activated RAAS)? Could the answer lie with changes in intra-renal AT1 or Mas receptor expression? Interestingly, the observed Ang (1-7) induced increases in sodium and water excretion in rats receiving either a low or normal sodium diet were and blocked in the presence of the AT 1 receptor antagonist (Losartan) in the presence of the, 'Mas' receptor antagonist (A-779). These data suggest that both AT1 and 'Mas' receptors need to be functional in order to fully mediate the renal responses to intra-renal Ang (1-7) infusion. Importantly, further experimentation also revealed that there is a proportional relationship between AT 1 receptor expression in the rat renal cortex and the magnitude of the excretory actions of intra renal Ang (1-7) infusion, which is only partially dependent on the level of 'Mas' receptor expression. These observations suggest that although Ang (1-7) induced increases in sodium and water excretion are mediated by the Mas receptor, the magnitude of these excretory responses appear to be dependent upon the level of AT 1 receptor expression and more specifically Ang II/ AT 1 receptor signalling. Thus in rats receiving a low sodium diet, Ang (1-7) acts via the Mas receptor to inhibit Ang II/ AT 1 receptor signalling. In rats receiving a high sodium diet the down regulated AT 1 receptor expression implies a reduction in Ang II/ AT 1 receptor signalling which renders the counter-regulatory effects of intra-renal Ang (1-7) infusion redundant.

MyRoom: A user-centred model of affective responsive architecture

Can my immediate physical environment affect how I feel? The instinctive answer to this question must be a resounding “yes”. What might seem a throwaway remark is increasingly borne out by research in environmental and behavioural psychology, and in the more recent discipline of Evidence-Based Design. Research outcomes are beginning to converge with findings in neuroscience and neurophysiology, as we discover more about how the human brain and body functions, and reacts to environmental stimuli. What we see, hear, touch, and sense affects each of us psychologically and, by extension, physically, on a continual basis. The physical characteristics of our daily environment thus have the capacity to profoundly affect all aspects of our functioning, from biological systems to cognitive ability. This has long been understood on an intuitive basis, and utilised on a more conscious basis by architects and other designers. Recent research in evidence-based design, coupled with advances in neurophysiology, confirm what have been previously held as commonalities, but also illuminate an almost frightening potential to do enormous good, or alternatively, terrible harm, by virtue of how we make our everyday surroundings. The thesis adopts a design methodology in its approach to exploring the potential use of wireless sensor networks in environments for elderly people. Vitruvian principles of “commodity, firmness and delight” inform the research process and become embedded in the final design proposals and research conclusions. The issue of person-environment fit becomes a key principle in describing a model of continuously-evolving responsive architecture which makes the individual user its focus, with the intention of promoting wellbeing. The key research questions are: What are the key system characteristics of an adaptive therapeutic single-room environment? How can embedded technologies be utilised to maximise the adaptive and therapeutic aspects of the personal life-space of an elderly person with dementia?.

Health in the medieval world: Regionality and the bioarchaeology of Ireland and Britain

This study assesses regional health patterns in early medieval Ireland and Britain by analysing and interpreting palaeopathological indicators of stress. This was achieved by incorporating the results of demographic and palaeopathological study into the specific historical contexts. Although relatively small islands, both are home to unique and diverse cultural, physical, and political landscapes, which could potentially affect the general health of the population in different ways. To accurately answer the research question, a bioarchaeological survey of six regions within both islands was carried out, specifically analysing and comparing the demographic profile and general health trends within each region with one another. Results from the analysis have demonstrated statistically significant differences within and between the islands. Inferring that even the more subtle differences observed within the cultural, physical, and political landscapes, such as in the case of Ireland and Britain, can and do affect general health trends. The health of early medieval Ireland and Britain appears to be significantly affected by the physical landscape, specifically a north/south divide. The most northerly regions, Scotland South and Ireland North, manifested higher levels of stress indicators when compared to the more southerly positioned regions. Although it can only be hypothesised what factors within these regions are causing, enhancing or buffering stress, the study has established the potential and necessity for regional work to be continued when interpreting the historical past of these two islands.

Medieval Irish vision literature: a genre study

This dissertation examines medieval literary accounts of visions of the afterlife with an origin or provenance in Ireland from the perspective of genre, analysing their structural and literary characteristics both synchronically and diachronically. To this end, I have developed a new typology of medieval vision literature. I address the question in what manner the internationally attested genre of vision literature is adapted and developed in an Irish literary milieu. I explore this central research question through an interrogation of the typological unity of the key texts, both in formal arrangement and in the eschatological themes they express. My analysis of the structure and rhetoric of these narratives reveals the primary role of identity strategies, question-and-answer patterns and exhortation for their narrative cohesion and didactic function. In addition, I was able to make a formal distinction at text-level between the adaptation of the genre as an autonomous unit and the adaptation of thematic motifs as topoi. This further enabled me to nuance the distribution of characteristic features in the genre. My analysis of the spatial and temporal aspects of the eschatological journey confirms a preoccupation with personal eschatology. It reveals a close connection between the development of the aspects of graded access and trial in the genre and a growing awareness of an interim state of the soul after death. Finally, my dissertation provides new editions, translations and analyses of primary sources. My research breaks new ground in the hitherto underexplored area of genre adaptation in Ireland. In addition, it contributes significantly to our understanding of the nature of vision literature both in an Irish and a European context, and to our knowledge of the transmission of eschatological thought in the Latin West.
