Description of a radially polarized Laguerre-Gauss beam beyond the paraxial approximation

Fifth-order corrected expressions for the fields of a radially polarized Laguerre-Gauss (R-TEMn1) laser beams are derived based on perturbative Lax series expansion. When the order of Laguerre polynomial is equal to zero, the corresponding beam reduces to the lowest-order radially polarized beam (R-TEM01). Simulation results show that the accuracy of the fifth-order correction for R-TEMn1 depends not only on the diffraction angle of the beam as R-TEM01 does, but also on the order of the beam.

SYNTHESIS AND X-RAY CRYSTAL-STRUCTURE OF THE SM-YLIDE COMPLEX, [(C5H5)3SMCH2P(ME)PH2]

The interaction of (C5H5)2SmCl.LiCl with one equivalent of Li[(CH2)(CH2) PPh2] in refluxing tetrahydrofuran gives the yellow complex [(C5H5)3SmCH2P (Me)Ph2] in 30% yield. The compound has been fully characterized by analytical, spectroscopic and X-ray diffraction methods.

Thomas Wolfe and the genre question: Beyond the "charge of autobiography"

The North Carolinian author Thomas Wolfe (1900‐1938) has long suffered under the “charge of autobiography,” which lingers to this day in critical assessments of his work. Criticism of Wolfe is frequently concerned with questions of generic classification, but since the 1950s, re‐assessments of Wolfe’s work have suggested that Wolfe’s “autobiographical fiction” exhibits a complexity that merits further investigation. Strides in autobiographical and narrative theory have prompted reconsiderations of texts that defy the artificial boundaries of autobiography and fiction. Wolfe has been somewhat neglected in the canon of American fiction of his era, but deserves to be reconsidered in terms of how he engages with the challenges and contradictions of writing about or around the self. This thesis investigates why Wolfe’s work has been the source of considerable critical discomfort and confusion with regard to the relationship between Wolfe’s life and his writing. It explores this issue through an examination of elements of Wolfe’s work that problematise categorisation. Firstly, it investigates the concept of Wolfe as “storyteller.” It explores the motivations and philosophies that underpin Wolfe’s work and his concept of himself as a teller of tales, and examines aspects of Wolfe’s writing process that have their roots in medieval traditions of the memorisation and recitation of tales. The thesis then conducts a detailed examination of how Wolfe describes the process of transforming his memory into narrative through writing. The latter half of the thesis examines narrative techniques used by Wolfe, firstly analysing his extensive use of the iterative and pseudo‐iterative modes, and then his unusual deployment of narrators and focalization. This project sheds light on elements of Wolfe’s approach to writing and narrative strategies that he employs that have previously been overlooked, and that have created considerable critical confusion with regard to the supposedly “autobiographical” genesis of his work.

BEYOND THE LIBRETTO: HOW THE COMPOSER GUIDES THE CREATION OF CHARACTER THREE CASE STUDIES

When performing in opera, a singer portrays a character. A libretto is used as the principal resource for the research. Music can also reveal insights into the composer’s ideas regarding characterization. This performance dissertation examines how musical devices such as genre, texture, meter, melody, instrumentation and form can be used to inform choices of characterization. Three roles from diverse operas were examined and performed. The first role, Estelle Oglethorpe in Later the Same Evening (2007) by John Musto (b 1954) was performed November 15, 16, 17, 18 2007. The second role, Dorabella in Così fan tutte (1789) by Wolfgang Amadeus Mozart (1756-1791) was performed April 20, 25, 27, 2008. The third role, Olga in Eugene Onegin (1878) by Pyotr Ilyich Tchaikovsky (1840-1893) was performed on April 19, 2009. All operas were presented by the University of Maryland Opera Studio at the Ina and Jack Kay Theater in the Clarice Smith Performing Arts Center, University of Maryland College Park. DVD recordings of all performances can be found in the University of Maryland library system.

Beyond the Orange and the Green. The Diversification of the Qualitative Social Research Landscape in Northern Ireland.

The Northern Ireland conflict has been described as one of the most over-researched conflicts in the world. However, this is a relatively recent development. For many years, when the conflict was most intense, social scientists in Northern Ireland were silent and not vocal. The sectarian violence that dominated the life in Northern Ireland as well as the fact that the country was a fundamentally unjust society contributed to this silence. However, since the peace process began in the mid 1990s, a growing number of qualitative studies have been published, utilising one-to-one interviews and focus group discussions, in order to "make people's voices heard" and deal with the consequences of the so-called "Troubles". This paper looks into the emergence of a qualitative social research landscape in Northern Ireland beyond the conflict and explores issues so far neglected. It is argued that a number of factors have contributed to this, among them the availability of research funding to voluntary and community sector organisations that use their data to influence policy-making and equality legislation in a country which is still deeply divided along socio-religious lines.
