Ballineaspigmore and Bishopstown House

Ballineaspig, anglicised Bishopstown, consists of two townlands which are Ballineaspigmore and Ballineaspigbeg. Taken together, both townlands oc­cupy an area identifiable in modern day terms as lying approximately be­tween the old Glasheen National School on the east side and what was, until recently, the University Farm Curraheen Road on the west. A townland is the smallest administrative land division in Ireland. Historians and other scholars are as yet inconclusive about the origins of these divisions. They are certainly as old as the seventeenth century. The townland with which this booklet is concerned is known as Ballineaspigmore. It extends west from the new Regional Hospital at Wilton and includes modern housing estates such as Uam-Var, Benvoirlich and Firgrove. The simplest translation of the townland name is the large land division of the bishop. To clarify a popular misconception, Bishopstown does not derive its name from the fact that in the early eighteenth century a bishop of Cork built his country residence there. The name is much older and can be found in sources dating back to the sixteenth century.

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.

An investigation of innovation and knowledge creation in virtual worlds

The Internet and World Wide Web have had, and continue to have, an incredible impact on our civilization. These technologies have radically influenced the way that society is organised and the manner in which people around the world communicate and interact. The structure and function of individual, social, organisational, economic and political life begin to resemble the digital network architectures upon which they are increasingly reliant. It is increasingly difficult to imagine how our ‘offline’ world would look or function without the ‘online’ world; it is becoming less meaningful to distinguish between the ‘actual’ and the ‘virtual’. Thus, the major architectural project of the twenty-first century is to “imagine, build, and enhance an interactive and ever changing cyberspace” (Lévy, 1997, p. 10). Virtual worlds are at the forefront of this evolving digital landscape. Virtual worlds have “critical implications for business, education, social sciences, and our society at large” (Messinger et al., 2009, p. 204). This study focuses on the possibilities of virtual worlds in terms of communication, collaboration, innovation and creativity. The concept of knowledge creation is at the core of this research. The study shows that scholars increasingly recognise that knowledge creation, as a socially enacted process, goes to the very heart of innovation. However, efforts to build upon these insights have struggled to escape the influence of the information processing paradigm of old and have failed to move beyond the persistent but problematic conceptualisation of knowledge creation in terms of tacit and explicit knowledge. Based on these insights, the study leverages extant research to develop the conceptual apparatus necessary to carry out an investigation of innovation and knowledge creation in virtual worlds. The study derives and articulates a set of definitions (of virtual worlds, innovation, knowledge and knowledge creation) to guide research. The study also leverages a number of extant theories in order to develop a preliminary framework to model knowledge creation in virtual worlds. Using a combination of participant observation and six case studies of innovative educational projects in Second Life, the study yields a range of insights into the process of knowledge creation in virtual worlds and into the factors that affect it. The study’s contributions to theory are expressed as a series of propositions and findings and are represented as a revised and empirically grounded theoretical framework of knowledge creation in virtual worlds. These findings highlight the importance of prior related knowledge and intrinsic motivation in terms of shaping and stimulating knowledge creation in virtual worlds. At the same time, they highlight the importance of meta-knowledge (knowledge about knowledge) in terms of guiding the knowledge creation process whilst revealing the diversity of behavioural approaches actually used to create knowledge in virtual worlds and. This theoretical framework is itself one of the chief contributions of the study and the analysis explores how it can be used to guide further research in virtual worlds and on knowledge creation. The study’s contributions to practice are presented as actionable guide to simulate knowledge creation in virtual worlds. This guide utilises a theoretically based classification of four knowledge-creator archetypes (the sage, the lore master, the artisan, and the apprentice) and derives an actionable set of behavioural prescriptions for each archetype. The study concludes with a discussion of the study’s implications in terms of future research.

FLT3-driven redox signalling in acute myeloid leukaemia

Acute myeloid leukaemia refers to cancer of the blood and bone marrow characterised by the rapid expansion of immature blasts of the myeloid lineage. The aberrant proliferation of these blasts interferes with normal haematopoiesis, resulting in symptoms such as anaemia, poor coagulation and infections. The molecular mechanisms underpinning acute myeloid leukaemia are multi-faceted and complex, with a range of diverse genetic and cytogenetic abnormalities giving rise to the acute myeloid leukaemia phenotype. Amongst the most common causative factors are mutations of the FLT3 gene, which codes for a growth factor receptor tyrosine kinase required by developing haematopoietic cells. Disruptions to this gene can result in constitutively active FLT3, driving the de-regulated proliferation of undifferentiated precursor blasts. FLT3-targeted drugs provide the opportunity to inhibit this oncogenic receptor, but over time can give rise to resistance within the blast population. The identification of targetable components of the FLT3 signalling pathway may allow for combination therapies to be used to impede the emergence of resistance. However, the intracellular signal transduction pathway of FLT3 is relatively obscure. The objective of this study is to further elucidate this pathway, with particular focus on the redox signalling element which is thought to be involved. Signalling via reactive oxygen species is becoming increasingly recognised as a crucial aspect of physiological and pathological processes within the cell. The first part of this study examined the effects of NADPH oxidase-derived reactive oxygen species on the tyrosine phosphorylation levels of acute myeloid leukaemia cell lines. Using two-dimensional phosphotyrosine immunoblotting, a range of proteins were identified as undergoing tyrosine phosphorylation in response to NADPH oxidase activity. Ezrin, a cytoskeletal regulatory protein and substrate of Src kinase, was selected for further study. The next part of this study established that NADPH oxidase is subject to regulation by FLT3. Both wild type and oncogenic FLT3 signalling were shown to affect the expression of a key NADPH oxidase subunit, p22phox, and FLT3 was also demonstrated to drive intracellular reactive oxygen species production. The NADPH oxidase target protein, Ezrin, undergoes phosphorylation on two tyrosine residues downstream of FLT3 signalling, an effect which was shown to be p22phox-dependent and which was attributed to the redox regulation of Src. The cytoskeletal associations of Ezrin and its established role in metastasis prompted the investigation of the effects of FLT3 and NADPH oxidase activity on the migration of acute myeloid leukaemia cell lines. It was found that inhibition of either FLT3 or NADPH oxidase negatively impacted on the motility of acute myeloid leukaemia cells. The final part of this study focused on the relationship between FLT3 signalling and phosphatase activity. It was determined, using phosphatase expression profiling and real-time PCR, that several phosphatases are subject to regulation at the levels of transcription and post-translational modification downstream of oncogenic FLT3 activity. In summary, this study demonstrates that FLT3 signal transduction utilises a NADPH oxidase-dependent redox element, which affects Src kinase, and modulates leukaemic cell migration through Ezrin. Furthermore, the expression and activity of several phosphatases is tightly linked to FLT3 signalling. This work reveals novel components of the FLT3 signalling cascade and indicates a range of potential therapeutic targets.

Legislative policy, law and competitiveness: a mysterious and difficult relationship in the EU

The Lisbon Agenda places Europe in a uniquely difficult position globally, most particularly as an example of a social and regulatory experiment which many consider to be doomed to failure. The drive towards economic competitiveness has led to a focus on regulation and its effect on entrepreneurship, productivity and business growth but assessing this relationship is complex for a number of reasons. First, not all regulatory effects can be predicted precisely in relation to behavioural outcomes. Path-dependency scholars have also demonstrated that the regulation will have varying effects depending on context. Second, theoretically it is clear that many non-regulatory factors may contribute to economic and competitive success. Third, there is evidence of internal conflict within the Commission as to the relative importance of the Lisbon goals. Finally, the experience of distinct Member States presents challenges both for assessment and prescriptive remedies. The Commission has estimated that the cost of regulatory compliance obligations on businesses in the EU is between 4% and 6% of gross domestic product and that 15% of this figure is avoidable 'red tape' (the term used specifically to signify unnecessary compliance burdens). This article proposes to assess the likely outcomes of de-regulation as we rapidly approach 2010, the year for attainment of the Lisbon goals.
