In search of Cork's collecting traditions: from Kilcrea's Library to the Boole Library of today

The objective of this essay is not a description of the presently unresearched, unstated and unquantified tradition of collectors, collecting and collectables in Cork; it is rather one of signposting what survives in terms of influences which coalesced into what became the bibliographical and museological resources of the Queen's College and ultimately University College, Cork (UCC).

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 Accessing as yet unpublished Department of Defence files, study analyses tension between the military authorities and the government.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.

Perceptions of leadership in the public library: a transnational study

This study explores the topic of leadership as perceived and practised by public library leaders. Library leaders have a wide-ranging impact on society but have been largely overlooked as the subject of serious study. Prior to this study, only one small interview-based study and five survey-based studies have been undertaken on public library leaders/leadership — all in North America. No study on the topic has been researched and published outside of North America. The current study is the most in-depth study to date, drawing on face-to-face interviews with thirty public library leaders. As this study was undertaken in three national jurisdictions — Ireland, Britain, and America — it is also the first transnational study on the topic. The study investigates library leaders’ perceptions of leadership, and critically explores if head librarians distinguish classic leadership from management practices, both conceptually and in their work lives. In addition to exploring core leadership issues, such as positive or negative traits, the study also investigates the perceptions of library leaders on matters closely connected with their careers. The study investigates the impact of public library leaders on their followers and on the broader society they serve. This study of the perceptions of senior public library leaders, across national boundaries, makes a theoretical contribution not just to leadership in librarianship, but also to the broader theory of library and information science, and in a limited way to the broad corpus of literature on organizational leadership. The study aims to develop an understanding of the perceptions of current leaders in the field of public librarianship. The results of the study show that leadership is a relatively scarce quality in public libraries in Ireland, Britain, and America. Many public library leaders focus on management and administration issues rather than leadership. The study also illustrates that varying leadership styles are practised by the interviewed librarians, and that there are no universal or common traits, even within national boundaries, for effective public library leadership. The implications of the study for both practising librarians and research literatures in librarianship and organizational leadership are also explored and a future research agenda developed.

"A Good Reder": the middle English Wise Book of Philosophy and Astronomy, instruction, publics, and manuscripts

The present work is a study of the Middle English prose text known as The Wise Book of Philosophy and Astronomy, a consideration of its transmission and reception history, and a survey of its manuscript witnesses; it also incorporates an edition of the text from two of its manuscripts. The text is a cosmological treatise of approximately five thousand words, written for the most part in English, with astronomical and astrological terms in Latin, though the English translation is frequently given. It is written anonymously, and survives in thirty-three manuscripts.

The identification and characterisation of Rab4 interacting proteins

Rab4 is a member of the Rab superfamily of small GTPases. It is localized to the early sorting endosome and plays a role in regulating the transport from this compartment to the recycling and degradative pathways. In order to further our understanding of the role Rab4 plays in endocytosis, a yeast two-hybrid screen was performed to identify putative Rab4 effectors. A constitutively active mutant of Rab4, Rab4Q67L, when used as bait to screen a HeLa cDNA library, identified a novel 80kDa protein that interacted with Rab4-GTP. This protein was called Rab Coupling Protein (RCP). RCP interacts preferentially with the GTP-bound form of Rab4. Subsequent work demonstrated that RCP also interacts with Rab11, and that this interaction is not nucleotide-depenedent. RCP is predominantly membrane-bound and localised to the perinuclear recycling compartment. Expression of a truncation mutant of RCP, that contains the Rab binding domain, in HeLa cells, results in the formation of an extensive tubular network that can be labelled with transferrin. These tubules are derived from the recycling compartment since they are inaccessible to transferrin when the ligand is internalised at 18oC. The truncation mutant-induced morphology can be rescued by overexpression of active Rab11, but not active Rab4. This suggests that RCP functions between Rab4 and Rab11 in the receptor recycling pathway, and may act as a ‘molecular bridge’ between these two sequentially acting small GTPases. Quantitative assays demonstrated that overexpression of the truncation mutant results in a dramatic inhibition in the rate of receptor recycling. Database analysis revealed that RCP belongs to a family of Rab interacting proteins, each characterised by a carboxy-terminal coiled-coil domain and an amino-terminal phospholipid-binding domain. KIAA0941, an RCP homologue, interacts with Rab11, but not with Rab4. Overexpression of its Rab binding domain also results in a tubular network, however, this tubulation cannot be rescued by active Rab11.

Phase estimation receiver for full-field detection: a novel receiver structure for electronic dispersion compensation of metropolitan area networks

The development of ultra high speed (~20 Gsamples/s) analogue to digital converters (ADCs), and the delayed deployment of 40 Gbit/s transmission due to the economic downturn, has stimulated the investigation of digital signal processing (DSP) techniques for compensation of optical transmission impairments. In the future, DSP will offer an entire suite of tools to compensate for optical impairments and facilitate the use of advanced modulation formats. Chromatic dispersion is a very significant impairment for high speed optical transmission. This thesis investigates a novel electronic method of dispersion compensation which allows for cost-effective accurate detection of the amplitude and phase of the optical field into the radio frequency domain. The first electronic dispersion compensation (EDC) schemes accessed only the amplitude information using square law detection and achieved an increase in transmission distances. This thesis presents a method by using a frequency sensitive filter to estimate the phase of the received optical field and, in conjunction with the amplitude information, the entire field can be digitised using ADCs. This allows DSP technologies to take the next step in optical communications without requiring complex coherent detection. This is of particular of interest in metropolitan area networks. The full-field receiver investigated requires only an additional asymmetrical Mach-Zehnder interferometer and balanced photodiode to achieve a 50% increase in EDC reach compared to amplitude only detection.

Coherent wavelength division multiplexing: a novel transmission format for high spectral density optical communication networks

In this thesis a novel transmission format, named Coherent Wavelength Division Multiplexing (CoWDM) for use in high information spectral density optical communication networks is proposed and studied. In chapter I a historical view of fibre optic communication systems as well as an overview of state of the art technology is presented to provide an introduction to the subject area. We see that, in general the aim of modern optical communication system designers is to provide high bandwidth services while reducing the overall cost per transmitted bit of information. In the remainder of the thesis a range of investigations, both of a theoretical and experimental nature are carried out using the CoWDM transmission format. These investigations are designed to consider features of CoWDM such as its dispersion tolerance, compatibility with forward error correction and suitability for use in currently installed long haul networks amongst others. A high bit rate optical test bed constructed at the Tyndall National Institute facilitated most of the experimental work outlined in this thesis and a collaboration with France Telecom enabled long haul transmission experiments using the CoWDM format to be carried out. An amount of research was also carried out on ancillary topics such as optical comb generation, forward error correction and phase stabilisation techniques. The aim of these investigations is to verify the suitability of CoWDM as a cost effective solution for use in both current and future high bit rate optical communication networks

A king for the queene: Samuel Sheppard's the faerie king and his reception of Spenser's epic authority

This thesis is the study of the use and abuse of Edmund Spenser as an authority in native English epic literature of the early seventeenth century, within fifty years of his death. It focuses on attempts to emulate or adapt his seminal text, The Faerie Queene (1596), and offers a comparative analysis of two such approaches by the liminal authors, Ralph Knevet and Samuel Sheppard. The former, a tutor to the wealthy Norfolk Paston family, produced his A Supplement of the Ferie Queene in the pre-Civil War period (c.1630-1635), while the latter wrote The Faerie King at the very end of the social upheaval of the war (c.1648-54). The thesis privileges the study of the holograph manuscripts (Cambridge University Library, MS Ee.3.53 and Bodleian Library MS Rawl. Poet. 28 respectively) over the basic editions of these neglected texts. It argues for the need to re-evaluate the significance of such texts within the Spenserian canon and, through new readings of the texts' structures and contexts, the thesis questions the legitimacy of canon formation and continuation, as well as the influence editorial policies and decision making can have on subsequent readers and receptions of the text
