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.

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

BACH TO BASICS: A PERFORMANCE STUDY OF THE SUITES FOR SOLO CELLO BY JOHANN SEBASTIAN BACH, BWV 1007-1012

This dissertation project focuses on J.S. Bach's Six Suites and explores the ideology of the Suites as etudes versus concert pieces. It is my belief that the evolution of the rank of the Suites in a cellist's repertoire today represents more than just historical coincidence. My premise is that the true genius of the Suites lies in their dual role as !&I efficient teaching pieces and superior performance works. Consequently, the maximum use of Bach's Six Suites as pedagogical material heightens both technical ability and deeper appreciation of the art. The dual nature of the Suites must always be emphasized: not only do these pieces provide innumerable opportunities for building cello technique, but they also offer material for learning the fundamentals of melody, harmony, dynamics, phrasing and texture. It is widely accepted among academic musicians that Bach's keyboard music serves as perfect compositions -- the model for music theory, music form and music counterpoint. I argue that we should employ the Cello Suites to this same end. The order in which the Suites are presented was deliberately chosen to highlight the contrasts in the pieces. Because the technical demands of each suite grow progressively from the previous one, they were performed non-consecutively in order to balance the difficulty and depth of each recital. The first compact disc consists of the Third Suite in C Major and Fifth Suite in C minor (with scordatura tuning), emphasizing the parallel keys. The Second Suite in D Minor and the Fourth Suite in E-flat Major comprises the compact disc. Finally, in the third compact disc, the First Suite in G Major and the Sixth Suite in D Major (composed for the five string cello piccola, but played here on a four-string cello) highlights the progression of the Suites.

A C-terminal motif found in the beta2-adrenergic receptor, P2Y1 receptor and cystic fibrosis transmembrane conductance regulator determines binding to the Na+/H+ exchanger regulatory factor family of PDZ proteins.

The Na+/H+ exchanger regulatory factor (NHERF) binds to the tail of the beta2-adrenergic receptor and plays a role in adrenergic regulation of Na+/H+ exchange. NHERF contains two PDZ domains, the first of which is required for its interaction with the beta2 receptor. Mutagenesis studies of the beta2 receptor tail revealed that the optimal C-terminal motif for binding to the first PDZ domain of NHERF is D-S/T-x-L, a motif distinct from those recognized by other PDZ domains. The first PDZ domain of NHERF-2, a protein that is 52% identical to NHERF and also known as E3KARP, SIP-1, and TKA-1, exhibits binding preferences very similar to those of the first PDZ domain of NHERF. The delineation of the preferred binding motif for the first PDZ domain of the NHERF family of proteins allows for predictions for other proteins that may interact with NHERF or NHERF-2. For example, as would be predicted from the beta2 receptor tail mutagenesis studies, NHERF binds to the tail of the purinergic P2Y1 receptor, a seven-transmembrane receptor with an intracellular C-terminal tail ending in D-T-S-L. NHERF also binds to the tail of the cystic fibrosis transmembrane conductance regulator, which ends in D-T-R-L. Because the preferred binding motif of the first PDZ domain of the NHERF family of proteins is found at the C termini of a variety of intracellular proteins, NHERF and NHERF-2 may be multifunctional adaptor proteins involved in many previously unsuspected aspects of intracellular signaling.

The Many Faces of Paul Hindemith

The purpose of this project is to present selected violin pieces by Paul Hindemith (1895-1963) against a backdrop of the diverse styles and traditions that he integrated in his music. For this dissertation project, selected violin sonatas by Hindemith were performed in three recitals alongside pieces by other German and Austro-German composers. These recitals were also recorded for archival purposes. The first recital, performed with pianist David Ballena on December 10, 2005, in Gildenhorn Recital Hall at the University of Maryland, College Park, included Violin Sonata Op.11, No. 1 (1918) by Paul Hindemith, Sonatina in D Major, Op. 137 (1816) by Franz Schubert, and Sonata in E-flat Major, Op.18 (1887) by Richard Strauss. The second recital, performed with pianist David Ballena on May 9, 2006, in Gildenhorn Recital Hall at the University of Maryland, included Sonata in E Minor, KV 304 (1778) by Wolfgang Amadeus Mozart, Sonata in E (1935) by Paul Hindemith, Romance for Violin and Orchestra No.1 in G Major (1800-1802) by Ludwig Van Beethoven, and Sonata for Violin and Piano in A minor, Op. 105 (1851) by Robert Schumann. The third recital, performed with David Ballena and Kai-Ching Chang on November 10, 2006 in Ulrich Recital Hall at the University of Maryland, included Violin Sonata Op.12 No.1 in D Major (1798) by Ludwig Van Beethoven, Sonata for Violin and Harpsichord No.4 in C Minor BWV 1017 (1720) by J.S. Bach, and Violin Sonata Op.11 No.2 (1918) by Paul Hindemith. For each of my dissertation recitals, I picked a piece by Hindemith as the core of the program then picked pieces by other composers that have similar key, similar texture, same number of movements or similar feeling to complete my program. Although his pieces used some classical methods of composition, he added his own distinct style: extension of chromaticism; his prominent use of interval of the fourth; his chromatic alteration of diatonic scale degrees; and his non-traditional cadences. Hindemith left behind a legacy of multi-dimensional, and innovative music capable of expressing both the old and the new aesthetics.

Dinámica del carbono en sistemas agrícolas bajo siembra directa : nuevas evidencias obtenidas mediante el uso de 13 C sobre la importancia de las raíces, la calidad de los residuos y el laboreo

El carbono orgánico del suelo (COS) es uno de los principales determinantes de la productividad de los ecosistemas, afectando la fertilidad del suelo y su capacidad de secuestrar CO2. La agricultura es uno de los principales cambios de uso del suelo que afecta significativamente el COS. En esta tesis se examinan, mediante experimentos de campo y usando al 13C como trazador isotópico, tres aspectos de la dinámica de C en sistemas agrícolas: 1) la importancia de las raíces en la formación de COS, 2) los efectos de la cantidad y calidad de los residuos sobre la tasa de descomposición y humificación del COS y 3) la dinámica del COS en sistemas de agricultura continua iniciados sobre pastizales naturales nunca laboreados. Los resultados obtenidos muestran que 1) en cultivos de soja y maíz, la formación de COS se deriva principalmente de la biomasa subterránea y en menor medida de los residuos aéreos, al menos en la fracción de la materia orgánica particulada (MOP). También, se observó 2) que el agregado de residuos de maíz con alta relación C:N aumentó la tasa de descomposición de la MOAM (materia orgánica asociada a los minerales) cuando se la compara con el agregado de residuos de soja (baja relación C:N), efecto conocido como priming. Sin embargo, también existió una mayor formación de materia orgánica bajo cultivos de maíz, y por ende se conservaron las reservas de COS, pero su ciclado fue más rápido. Finalmente, 3) los cultivos en sistemas de siembra directa establecidos sobre suelos nunca laboreados presentaron niveles de COS similares a los de los pastizales naturales remplazados. Estos resultados cuestionan parte de nuestro conocimiento sobre los sistemas agrícolas bajo siembra directa, aportando nuevas evidencias experimentales y destacando el uso de marcadores isotópicos de 13C para comprender el flujo de C en los agroecosistemas.

'Dare the boist'rous main': the role of the Belfast Newsletter in the process of emigration from Ulster to North America 1760-1800

Before the mass migrations from Ireland in the nineteenth century, earlier waves of migration in the eighteenth century saw significant numbers of people leave Ireland, predominantly from Ulster, to settle in North America. This article, using as its principal data source the Belfast News Letter ( BNL), its letters, advertisements and reports, focuses firstly on reconstructing the late eighteenth-century migration process and voyage, highlighting the barriers represented by the Atlantic Ocean. In addition to the challenges of the sea, there were problems with the ships, the ever-present danger of disease and also threats from other vessels, from privateers to press gangs. The voyage was recognized as a ‘universal dread’, and the risks taken to ‘dare the boist’rous main’ were perhaps not minimized in the pages of the BNL, whose editorial stance was antipathetic to the migration for the potential harm it caused to Ulster by removing so many of its industrious young. The second part of this article goes on to consider the newspaper’s and others’ vested interests in the emigration process, demonstrates how these were manifested in the press and sets the coverage of this very significant early emigration flow within the context of contemporary religious and colonial discourses at a period of very lively transatlantic interactions.

Variability of Nt-proANP and C-ANP

Background Natriuretic peptides are frequently measured in patients with chronic cardiac failure (CCF). We set out to compare the variability of atrial natriuretic peptide (C-ANP) and its precursor N-terminal pro-ANP (Nt-proANP) to decide which would be more suitable for routine use.

The influence of gender in the direction of Spanish cooperative societies on profitability and indebtedness: an empirical analysis

In this paper the claim for the market for a new business management to ensure the presence of women in decision -making to respond to new social needs addressed. Thus, this paper analyzes the influence of gender diversity of the directors on the profitability and the level of debt for a sample of 5,199 Spanish cooperatives. Unlike capitalist societies, these organizations have a number of peculiarities in their government, and that the partners are themselves major time, agents and customers. The study focuses on the Spanish context, where there is an open debate on the importance of women's business management, as in other countries, driven by the proliferation of legislation on gender equality, being, in addition, Spain, the pioneer in having specific legislation on Social Economy. The results show that cooperatives with greater female representation in theirs Boards have higher profitability. On the other hand, those Boards with a higher percentage of women show a lower level of indebtedness.
