A cursory glance at cello works by English composers during the twentieth- century yields an unexpected relationship to Russian musicians, history, culture, and religion. One must wonder how this connection or "Russian thread" came to be. When considering the working relationship of Benjamin Britten and Mstislav Rostropovich, the likelihood of such a connection is tangible, since their deeply personal friendship influenced Britten's music for cello. However, what is perhaps more interesting is the emergence of connections to Russia in the works of other English composers of the twentieth-century, featuring works from 1913-1996. This project was conceived after close study and analysis of Benjamin Britten's Third Suite for Solo Cello, Op. 87 (1971). Britten's inclusion of Russian folk tunes and an Orthodox Church hymn signaled the penetrating presence of Russian elements in his works. Britten's First Suite for Solo Cello, Op. 72, Third Suite for Cello, Op. 87, and Sonata for Piano and Cello in C, Op. 65 are presented in this project. Further exploration of works for cello by English composers unveiled similar connections to Russia. The Sonata for Cello and Piano of Frank Bridge is likened to Russian romanticism and the Cello Sonata of Sergei Rachmaninoff. William Walton's Cello Concerto was written for the Russian-American cellist Gregor Piatigorsky. Wake Up ...and die is John Tavener's deeply spiritual work, which is rooted in his Russian Orthodoxy. John Ireland, influenced by models of French and Russian Impressionism, contributed works colored with Russian folk influences, of which his Piano Trio No. 2 is an example. Finally, Arnold Bax traveled to Russia as a young man and his Folk Tale and Legend Sonata are imbued with the spirit of Russian folk music and architecture. This dissertation project is comprised of three recitals featuring English works for cello connected by a "Russian Thread." All events took place on the campus of University of Maryland, College Park: Recital #1 on December 4, 2011 in the Gildenhorn Recital Hall of the Clarice Smith Performing Arts Center, Recital #2 on February 11,2012, and Recital #3 on April 15, 2012, both in the Ulrich Recital Hall.

En los ecosistemas de llanuras, como la Llanura Pampeana Argentina, los flujos en sentido vertical - transpiración y evaporación directa - son las principales vías evaporativas de salida de agua. La vegetación controla las salidas transpirativas, por ello la cobertura del suelo tiene una gran influencia en el funcionamiento ecosistémico. Aún no se conoce con certeza cómo el uso del suelo y sus modificaciones condicionan el régimen de inundaciones. Los objetivos de este trabajo son i) describir los eventos de anegamiento de un área representativa de la Pampa Interior para un período de 11 años; ii) analizar el impacto de la frecuencia de anegamiento sobre el funcionamiento de la vegetación a escala regional y iii) a escala local. Se evaluó de qué manera la frecuencia de anegamiento y el tipo de cobertura condicionan la respuesta de la vegetación frente a una inundación utilizando información satelital del período 2000-2010. Se utilizó el IVN obtenido del producto MODIS MOD13Q1 como indicador de transpiración y mapas de anegamiento. Los resultados muestran que a mayor frecuencia de anegamiento se registra un mayor descenso de la transpiración y mayor tiempo de recuperación con respecto a los sitios no anegados. El impacto negativo del anegamiento sobre cultivos anuales es mayor que sobre especies forrajeras, las cuales conservan las tasas de transpiración a pesar de estar anegadas. Esto sugiere que bajo el uso de la tierra actual de la región donde se reemplazan los esquemas de rotación por cultivos anuales, los futuros eventos de inundación pueden perdurar más tiempo debido a menores tasas de transpiración durante estos eventos. Para evitar este riesgo habría que mantener un mayor porcentaje de heterogeneidad del paisaje.

Until now, the study of literary allusion has focused on allusions made by poets to other poets. In Tennyson Among the Novelists, John Morton presents the first book-length account of the presence of a poet’s work in works of prose fiction. As well as shedding new light on the poems of Tennyson and their reception history, Morton covers a wide variety of novelists including Thomas Hardy, James Joyce, Evelyn Waugh, and Andrew O’Hagan, offering a fresh look at their approach to writing. Morton shows how Tennyson’s poetry, despite its frequent depreciation by critics, has survived as a vivifying presence in the novel from the Victorian period to the present day.

A juzgar por alguna declaración más bien negativa de Borges sobre la literatura española, se podría creer que esta no influyó demasiado en él. Sin embargo, existen indicios de que pudo haberse inspirado también en determinados escritores españoles coetáneos hoy casi olvidados. Uno de ellos pudo ser José María Salaverría, entre cuyos relatos destaca “El fichero supremo” (1926), del que se ha dicho que “anticipa algunas de las preocupaciones características de un tipo de relato que Jorge Luis Borges elevará años después a la máxima categoría estética”. De hecho, recuerda a “La biblioteca de Babel” (1941) borgiana por su planteamiento hasta el punto de que podría pensarse que el maestro argentino pudo tener presente, a la hora de escribir esa obra maestra, ese cuento de Salaverría, el cual se publicó por primera vez en Caras y Caretas, una revista porteña que Borges reconoció “devorar” en su juventud. Sin embargo, el interés mayor de la comparación entre “El fichero supremo” y “La biblioteca de Babel” no radica tanto en el carácter de posible fuente del primero como en el contraste entre sus formas de presentación narrativa: desde fuera y en tercera persona en Salaverría, en un marco realista; y desde dentro y en primera persona, prácticamente sin marco, en Borges. Este parece desarrollar, en el registro propio de la “imaginación razonada” descrito por él mismo, una virtualidad presente en el relato de Salaverría, cuya comparación con “La biblioteca de Babel” puede suscitar también alguna reflexión sobre el enigma de la identidad y el carácter de la voz enunciadora de la biblioteca universal de Babel. Al menos, esta parece haber hecho realidad en cierto modo, de forma sublime, el patético sueño divino del archivero imaginado por Salaverría.

Freshwater resources in past diets can lead to inaccuracies when attempts are made to ascertain their radiocarbon ages or those of the consumers. Radiocarbon reservoir effects may lead to significant age offsets when the bones or other tissues of these consumers are radiocarbon dated. A number of recent studies have investigated freshwater reservoir offsets. However no study thus far has satisfactorily obtained a ubiquitous freshwater reservoir correction due to variability in the ecosystems analysed. This study tests the possibility of predicting freshwater reservoir effects from the carbonate alkalinity of the water with measurements on modern fish bone and water samples. A predictive capability would be especially valuable in the absence of well-preserved archaeological fish bone. We surveyed samples from lakes and rivers in varying geological settings in Britain and Ireland. Modern fish bone and water samples were analysed to investigate modern radiocarbon offsets from the atmosphere. Archaeological fish bone was also analysed to examine past reservoir offsets at selected sites. Stable carbon and nitrogen isotope values were measured to aid in interpretation of any variability in the offsets. Large freshwater reservoir offsets were measured in some modern and archaeological samples (maximum offset = 1638 14C years). The freshwater reservoir offsets in the fish bone were highly correlated with alkalinity of water in modern lake sites analysed. However, a high amount of variation within and between fish species was also evident in the results, precluding the possibility of providing regional corrections for freshwater reservoir offsets from alkalinity although this still may provide a general guideline. The variability is thought to be due to differences in the diet of individual fish.

The construction industry notoriously excels at dispute creation both in Ireland and abroad. This paper examines mediation in the Irish construction industry as a means of conflict and dispute resolution. It aims to identify success factors for appropriate competencies and processes required by mediators and other parties operating in the construction industry. Methodology includes a thorough review of the literature, followed by detailed interviews from industry experts to elicit and highlight the core competencies required. To aid in the analysis, qualitative analysis using mind mapping software was used. The findings suggest that facilitative mediation was best suited for the Irish construction industry. 13 and 17 success factors were identified as key skills necessary for a mediator and for a successful mediation process. For the skills, it ranges across behavioural, technical and intellectual skills. The mediation process factors can be split into actions of the mediator and other parties in the dispute. The results are similar to those identified in other countries and provide a good reference point for the development of the global construction industry. By following the findings of this report mediators and parties in dispute can improve processes and be more successful in mediation outcomes as a means of resolving conflicts and dispute.

Escherichia coli K-12 WcaJ and the Caulobacter crescentus HfsE, PssY, and PssZ enzymes are predicted to initiate the synthesis of colanic acid (CA) capsule and holdfast polysaccharide, respectively. These proteins belong to a prokaryotic family of membrane enzymes that catalyze the formation of a phosphoanhydride bond joining a hexose-1-phosphate with undecaprenyl phosphate (Und-P). In this study, in vivo complementation assays of an E. coli K-12 wcaJ mutant demonstrated that WcaJ and PssY can complement CA synthesis. Furthermore, WcaJ can restore holdfast production in C. crescentus. In vitro transferase assays demonstrated that both WcaJ and PssY utilize UDP-glucose but not UDP-galactose. However, in a strain of Salmonella enterica serovar Typhimurium deficient in the WbaP O antigen initiating galactosyltransferase, complementation with WcaJ or PssY resulted in O-antigen production. Gas chromatography-mass spectrometry (GC-MS) analysis of the lipopolysaccharide (LPS) revealed the attachment of both CA and O-antigen molecules to lipid A-core oligosaccharide (OS). Therefore, while UDP-glucose is the preferred substrate of WcaJ and PssY, these enzymes can also utilize UDP-galactose. This unexpected feature of WcaJ and PssY may help to map specific residues responsible for the nucleotide diphosphate specificity of these or similar enzymes. Also, the reconstitution of O-antigen synthesis in Salmonella, CA capsule synthesis in E. coli, and holdfast synthesis provide biological assays of high sensitivity to examine the sugar-1-phosphate transferase specificity of heterologous proteins.

In recent years there has been a remarkable surge of interest in the concept of punitiveness in theoretical criminology. Accounts serve to emphasise rupture over continuity, drawing attention to the increased focus on managerialism, risk and expressive penal policies in countries such as England and the US. Criticisms of these accounts have drawn attention to the weak empirical base for such assertions and the continued relevance of local cultural, historical and political conditions in mediating the effect of more punitive trends. In light of the relative neglect of smaller jurisdictions in this literature it was decided to locate these debates in three small common law jurisdictions, namely, Ireland, Scotland and New Zealand over the period 1976-2006 with a view to assessing the empirical evidence for penal change. This was done using a broader definition of punitiveness than normally employed incorporating indices relating to the ‘front end’ (eg police powers) as well as the ‘back end’ (eg prison and probation) of the criminal justice system. Data were collected on the three case studies using a multi-method approach involving examination of extensive quantitative data, interviews with key criminal justice stakeholders and documentary analysis. The data provide some support for the ‘new punitiveness’ thesis in these countries through a pattern of increased legislative activity aimed at controlling violent and sexual offenders and significant increases in the lengths of sentences imposed. However, analysis of qualitative data and a larger number of variables reveals distinctly different patterns of punitiveness over the thirty year period in the three countries. It is argued that the study holds important lessons for comparative criminology into the ‘new punitiveness’. There is a need for qualitative as well as quantitative data; for multiple rather than singular indices across a wide range of areas (juvenile justice, prison conditions, etc); and for ‘front end’ as well as ‘back end’ indices.

1. Freshwater unionoids are one of the most threatened animal groups worldwide and the freshwater pearl mussel Margaritifera margaritifera is currently listed as critically endangered in Europe. The ‘EC Habitats & Species Directive’ requires that EU member states monitor the distribution and abundance of this species and report regularly on its conservation status.
2. The pearl mussel meta-population in Northern Ireland was surveyed to assess temporal population trends in Special Areas of Conservation (SACs) and mussel reproduction throughout its range.
3. Mussels occurred in six rivers and numbers within three SAC designated sites remained stable between 2004-07 and 2011. The discovery of >8,000 previously unknown individuals in the Owenreagh River contributed to an overall increase (+56.8%) in the total known population. All populations actively reproduced during 2010 with approximately half of all individuals gravid. Moreover, suitable salmonid hosts occurred at all sites with 10.7% of salmon and 22.8% of trout carrying encysted glochidia. Populations were composed entirely of aged individuals with little evidence of recent recruitment.
4. We infer that the break in the life cycle must occur during the juvenile stage when glochidia metamorphose and settle into the interstitial spaces within the substrate. Water quality parameters, most notably levels of suspended solids, exceeded the recommended maximum thresholds in all rivers.
5. We posit that the deposition of silt may be the main cause of juvenile mortality contributing to a lack of recruitment. Consequently, all populations were judged to be in ‘unfavourable’ conservation status. Catchment-level management plans are urgently needed to reduce siltation with the aim of improving recruitment. Our results have implications for the success of ex-situ conservation programmes; specifically, the size at which captive bred juveniles are released into the wild. Further research is required to assess the vulnerabilities of early life stages of M. margaritifera to siltation.
