Vigiliae Christianae, Supplements, Volume: 150In this paper I want to take you on a walk through a garden. It is, to be sure, an imaginary garden; nevertheless, it bears a significance which extends beyond itself. Some of this significance concerns words and texts: for as we shall see, the garden is, amongst other things, a ‘garden of rhetoric’. The garden in question appears in the Gregory of Nyssa’s Homilies on the Song of Songs.[...
The ‘insider/outsider’ dilemma of ethnography: Working with young children and their families in cross-cultural contexts
No full textIn this article we unravel the difficulty of being researchers in the homes and classrooms of children and
their families whose origins are, for one of us, very different and, for the other, very similar to our own.
We first situate our work within theories of early socialization and literacy teaching which underpin our
understanding of how young children in cross-cultural contexts learn. We then turn to the question of
working with the families and teachers of these children which poses dilemmas not explained by the theories
presented. We illustrate these through a series of vignettes typifying both the ‘Outsider’ and the ‘Insider’ role.
The stories highlight paradigmatic moments of complexity, clashes or collusion which we unpick in terms of
their generalizability for others working in the field. Finally, we extend theories of dialogue in our search for
a methodology for collaborative work in future cross-cultural ethnographic studies

The Unity and Equality of the Divine Relations in Gregory of Nazianzus' Trinitarian Theology
No full textIn this thesis, the author examines how Gregory of Nazianzus distinguishes between the Father, Son, and Holy Spirit, while maintaining their equality and unity. In the first chapter, he examines the way theological discourse shapes Gregory's understanding of how words are predicated of God. In chapter 2, the author explores Gregory's understanding of the divine persons whom he distinguishes only on account of their subsistent relations of origin. In the final chapter, the author indicates problems with the modern scholarly interpretation of Gregory that identifies the unity and equality of the divine persons exclusively with the person of the Father. It is concluded that Gregory relied upon the notion of the homoousios in order to establish and guarantee the divine equality and unity among the persons.ThesisMaster of Arts (MA
Villain, victim or prophet?: William Gregory and the Great Famine
No full textThe name of Sir William Gregory features in most modern accounts of Ireland in the nineteenth century. It is fair to say, however, that usually he is regarded as a ‘villain’. Gregory is very widely known as the author of a piece of legislation introduced as part of relief measures during the Famine which sought to limit aid to those with a quarter acre or under of land and which became known as the Gregory clause or the quarter acre clause. An article in the New York Times on 16 July 2002 about the dedication of an Irish famine memorial in New York described the 5 million-dollar monument as follows: ‘The quarter-acre size of the monument adheres to the infamous Gregory clause passed by the British parliament in 1847, which decreed that cottiers whose plots exceeded that size would not be eligible for relief. The cottage is roofless because many farmers tore the thatches off their homes to prove destitution and qualify for relief.’ Most modern academic accounts of the Famine have been very critical of Gregory. It is widely accepted that the purpose of the Gregory clause was to assist landlords to clear their estates of pauperised smallholders who were paying little or no rent. This measure has been seen by some as leading to mass evictions and causing the clearance of many small farmers and labourers throughout Ireland.</jats:p
Backgrounds and Efficiencies for Low-Energy Searches, and Improved Calibration Techniques in the LUX-ZEPLIN Dark Matter Experiment
No full textThe full understanding of dark matter has eluded physicists for many years. While there is abundant astrophysical evidence across many scales, the exact nature of this matter, which comprises about 25% of the Universe’s energy density, remains unknown. Weakly Interacting Massive Particles (WIMPs) are one of the leading theoretical candidates, and numerous ex- periments have searched for their interactions. In recent decades, dual-phase Time Projection Chambers (TPCs) have become the leading technology in this search. The LUX-ZEPLIN (LZ) detector is one such xenon-based experiment, operating nearly a mile underground in the Black Hills of South Dakota at the Sanford Underground Research Facility (SURF). LZ contains 7 tonnes of active liquid xenon, of which about 5.5 tonnes comprise the central target within the TPC. Incoming radiation produces two signals: a prompt scintil- lation (S1) and a delayed electroluminescence (S2). By combining these two observables, LZ can reconstruct event energy and position with high precision and discriminate between signal and background. In addition to its flagship S1+S2 WIMP search, LZ also enables specialized analyses that extend its reach and refine its calibration framework. The first focus of this thesis is an S2-only analysis, which forgoes the S1 signal entirely to extend sensitivity to lower- energy depositions and lighter dark matter candidates. This approach introduces unique challenges, particularly from cathode-related backgrounds that cannot be rejected without drift-time information. My work develops data-driven methods to estimate these background rates and evaluates the efficiency of event selection cuts. The second focus of this thesis is a Doke plot analysis, which employs monoenergetic calibration sources to measure the detector gains g1 (light collection) and g2 (charge am- plification). These parameters underpin the conversion of observed signals into a common energy scale and are essential for all LZ science analyses. Here, we perform the traditional Doke analysis, extend it to include monoenergetic alpha peaks, study time-binned behavior relative to detector operational conditions, and analyze individual ER calibration sources. Together, these studies broaden LZ’s discovery reach and refine its calibration accuracy, enhancing the experiment’s overall sensitivity to rare dark matter interactions
Carbon nanotube composite scaffolds for differentiation of human neural stem cells
No full textCarbon nanotubes have been utilized in a variety of fields due to their unique and extraordinary properties. Here, a process to incorporate single-walled carbon nanotubes (SWNTs) into electrospun polymer mats is investigated in order to create novel composite scaffolds to enhance the differentiation of human neural stem cells (hNSCs) into fully developed neurons. An electrowetting method is first explored using a potential difference as a driving force. Although successful wetting was achieved, a vacuum impregnation method was used to further improve the uniformity of the SWNT distribution in the scaffold. This process produced homogenously wetted scaffolds that are electrically conductive, mechanically robust, and highly biocompatible with hNSC cultures in vitro. These scaffolds showed an increased expression of two major neuronal markers, Neurofilament M (NFM) and microtubule-associated protein-2 (MAP2) compared to plain electrospun polymer scaffolds. During differentiation tests, an additional electrical stimulation was applied and showed even further enhancement. This is the first demonstration of electrical stimulation enhancing neuronal differentiation of human neural stem cells on CNT-based composite scaffolds.M.S.Includes bibliographical referencesby Gregory Hede
Distribution, growth rates, and diagenesis of coralline algal structures on the Flower Garden Banks, northwestern Gulf of Mexico
No full textTypescript (photocopy).The East and West Flower Garden Banks are located in the northwestern Gulf of Mexico, approximately 190 km SSE of Galveston, Texas. These bathymetric highs are surface expressions of salt domes, and are two of the many offshore banks that have been extensively examined by Texas A&M University oceanographers during the past ten years. Although the crests of the East and West Flower Gardens are capped by living coral reefs with 18 species of hermatypic corals (20-50 m depths), crustose coralline algae are the primary framework builders and sediment contributors below 50 m. A depth zonation spanning 20-90 meters has been established on the banks and slopes using eleven genera of corallines (Lithothamnium, Mesophyllum, Melobesia, Archaeolithothamnium, Lithophyllum, Tenarea, Hydrolithon, Porolithon, Paragoniolithon, Lithoporella, and Fosliella), one squamariacean (Peyssonnelia spp.), and an encrusting foraminifer (Gypsina plana). On the upper coral reefs, the most common coralline algae genera are Hydrolithon, Lithoporella, Lithophyllum, Paragoniolithon, and Porolithon. On the flanks of the East Flower Gardens, coralline algae have stabilized ridges of coral debris at 30-35 m depths. These Madracis-algal ridges also support a lush growth of leafy brown algae owing to the absence of intensive grazing, which is typical of the main coral reefs. Between depths of 50-75 m, vast fields of coralline algal nodules, ranging in size from 1-20 cm, cover 60-90% of the bottom. There is a general increase in nodule size with depth. The algal nodule zone can be roughly divided into upper and lower units on the basis of coralline taxonomic composition and the internal structural morphology of the nodules. Nodules decrease in abundance below 75-80 m, and laterally extensive coralline algal pavements and rigid, 1-2 m high algal reefs become the dominant structures. Lithothamnium, Tenarea, and Peyssonnelia are the primary framework builders between 75-90 m. Although constructional void space in the algal reefs is high, most of these cavities have been occluded by micritic high-Mg calcite, the most common cement in algal reefs and nodules. Aragonite cement is also common, especially as spherulites and botryoidal aggregates in coral-line conceptacle voids. The internal morphology and taxonomic composition distinguishes these deep water algal reefs from shallow water algal ridges and cup reefs described by previous authors. . . .
