An examination of the efficacy of religious studies scholarship through a Kuhnian lens.

Irish dental practitioners perceived barriers to the care of patients with special healthcare needs and the effect of postgraduate training

Inequalities in oral healthcare service provision to people with special health needs have been reported in the Republic of Ireland. These include higher unmet dental treatment needs and longer waiting period to access routine dental treatment than the general population. Aim: The aims of this study were to determine the groups of patients with special needs which pose a challenge to manage in the dental surgery and to examine perceived barriers to the care of these patients. We aimed to determine whether postgraduate training in the management of these patients increases the practitioners’ frequency of treatment and their desire for further training in this area. Methods: A questionnaire was used to survey 326 randomly selected dentists from the Dental Council’s register of dentists. Questionnaire and information sheets explaining the purpose of the survey, confidentiality and anonymity of the responses were posted to the dentists. Results: The results showed that children with intellectual disability posed the biggest challenge for dentists to manage in the dental surgery. Behaviour management issues and the degree of disability were perceived by many dentists as factors that would have high effects on their willingness to treat patients with special needs. Dentists who have postgraduate training in the management of patients with special needs were significantly more willing to treat these patients and to seek additional training in the future. Conclusion: There are links between the training and the willingness of practitioners to undertake dental treatment or patients with special healthcare needs.

Non-Consumptive Effects of Predators in Coral Reef Communities and the Indirect Consequences of Marine Protected Areas

Predators exert strong direct and indirect effects on ecological communities by intimidating their prey. Non-consumptive effects (NCEs) of predators are important features of many ecosystems and have changed the way we understand predator-prey interactions, but are not well understood in some systems. For my dissertation research I combined a variety of approaches to examine the effect of predation risk on herbivore foraging and reproductive behaviors in a coral reef ecosystem. In the first part of my dissertation, I investigated how diet and territoriality of herbivorous fish varied across multiple reefs with different levels of predator biomass in the Florida Keys National Marine Sanctuary. I show that both predator and damselfish abundance impacted diet diversity within populations for two herbivores in different ways. Additionally, reef protection and the associated recovery of large predators appeared to shape the trade-off reef herbivores made between territory size and quality. In the second part of my dissertation, I investigated context-dependent causal linkages between predation risk, herbivore foraging behavior and resource consumption in multiple field experiments. I found that reef complexity, predator hunting mode, light availability and prey hunger influenced prey perception of threat and their willingness to feed. This research argues for more emphasis on the role of predation risk in affecting individual herbivore foraging behavior in order to understand the implications of human-mediated predator removal and recovery in coral reef ecosystems.

The Plutarch’s Motive of "Descensus Animae" in "Nag Hammadi and the Corpus Hermeticum"

Al evaluar los contactos de Plutarco con otras culturas contemporáneas, los investigadores todavía no han llegado a un consenso acerca de la relación entre el queronense y la literatura cristiano-primitiva. Un buen ejemplo de esto aparece al atender al motivo de la creación del alma humana. La intención de las próximas páginas es, tras un análisis de los textos plutarqueos, atender a estos posibles contactos con NHC, los heresiólogos y el Corpus Hermeticum a fin de dilucidar sus similitudes y diferencias.

The Life of an Author: Samuel Egerton Brydges and the Copyright Act 1814

The history of literary copyright in nineteenth century Britain is dominated - understandably perhaps - by a preoccupation with the passing and impact of the Copyright Amendment Act 1842, so ably lobbied for by Sir Thomas Noon Talfourd. This article, however, draws attention away from the 1842 Act towards the Copyright Act 1814, the first legislative provision within British copyright law to introduce a lifetime term of protection for the author. Why and on what basis did the legislature do so?
In bringing a renewed attention to this often overlooked legislative measure, we consider the context and logic that underpinned to grant of a copyright term that was tethered to the life of the author. In doing so, we might also find a useful prism through which to look afresh at current copyright debates concerning the appropriate nature and scope of copyright protection in the 21st century.

A Study of pH Manipulation on Tumor Proliferation and the CTL Response

Adoptive Cell Transfer (ACT) Therapy is a cancer treatment that enhances and utilizes the body’s own immune system. However, this treatment has had limited success in clinical trials. We hypothesized that this is due to the immunosuppressive, acidic microenvironment of cancer tumors. We tested the effects of acidic, neutral, and basic environments in vitro on cytotoxic T lymphocyte (CTL) survival, activation, migration and killing ability and on cancer cell survival. We found that CTLs have most optimum survival, activation, and migration in a neutral environment, while the optimal extracellular conditions for EG-7 lymphoma are slightly acidic and B16-OVA melanoma survives best in physiological conditions. Future research should further study the killing ability of T cells in the three different environments and look to move to in vivo experiments.

The Effect of Dietary Tartrazine on Brain Dopamine and the Behavioral Symptoms of Attention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder is a neurodevelopmental disorder correlated with a decrease in brain dopamine and an increase in behavioral symptoms of hyperactivity and impulsivity. This experiment explored how tartrazine (Yellow #5) impacts these symptoms. After tartrazine administration to Spontaneously Hypertensive Rats (SHR), dopamine concentrations in regions of brain tissue were measured using Enzyme-Linked Immunosorbent Assay analysis. Behavioral testing with a T-maze and open field test measured impulsivity and hyperactivity, respectively. Results indicate that dietary tartrazine increases hyperactive behaviors in the SHR. However, results do not indicate a relationship between dietary tartrazine and brain dopamine. No conclusions regarding the relationship between dietary tartrazine and impulsivity were drawn.

Development of radiotracers for nuclear imaging of poly(ADP-ribose) polymerase-1 and the translocator protein in glioblastoma.

Glioblastoma (GBM) is a highly aggressive and fatal brain cancer that is associated with a number of diagnostic, therapeutic, and treatment monitoring challenges. At the time of writing, inhibition of a protein called poly (ADP-ribose) polymerase-1 (PARP-1) in combination with chemotherapy was being investigated as a novel approach for the treatment of these tumours. However, human studies have encountered toxicity problems due to sub-optimal PARP-1 inhibitor and chemotherapeutic dosing regiments. Nuclear imaging of PARP-1 could help to address these issues and provide additional insight into potential PARP-1 inhibitor resistance mechanisms. Furthermore, nuclear imaging of the translocator protein (TSPO) could be used to improve GBM diagnosis, pre-surgical planning, and treatment monitoring as TSPO is overexpressed by GBM lesions in good contrast to surrounding brain tissue. To date, relatively few nuclear imaging radiotracers have been discovered for PARP-1. On the other hand, numerous tracers exist for TSPO many of which have been investigated in humans. However, these TSPO radiotracers suffer from either poor pharmacokinetic properties or high sensitivity to human TSPO polymorphism that can affect their binding to TSPO. Bearing in mind the above and the high attrition rates associated with advancement of radiotracers to the clinic, there is a need for novel radiotracers that can be used to image PARP-1 and TSPO. This thesis reports the pre-clinical discovery programme that led to the identification of two potent PARP-1 inhibitors, 4 and 17, that were successfully radiolabelled to generate the potential SPECT and PET imaging agents [123I]-4 and [18F]-17 respectively. Evaluation of these radiotracers in mice bearing subcutaneous human GBM xenografts using ex vivo biodistribution techniques revealed that the agents were retained in tumour tissue due to specific PARP-1 binding. This thesis also describes the pre-clinical in vivo evaluation of [18F]-AB5186, which is a novel radiotracer discovered previously within the research group with potential for PET imaging of TSPO. Using ex vivo autoradiography and PET imaging the agent was revealed to accumulate in intracranial human GBM tumour xenografts in good contrast to surrounding brain tissue, which was due to specific binding to TSPO. The in vivo data for all three radiolabelled compounds warrants further pre-clinical investigations with potential for clinical advancement in mind.

The Plutarch’s Motive of Descensus Animae in Nag Hammadi and the Corpus Hermeticum

In evaluating Plutarch’s contacts with other cultures of his era, scholars have not reached consensus so far regarding the relationship between the Chaironean and Early Christian writers. A good example of this lack of consensus rises when we come to the views of the creation of human soul. The aim of the following paper is to deal with those contacts by, after an analysis of Plutarch’s texts, taking into an account the sources of NHC, heresiologists, and also the contemporary Corpus Hermeticum in order to highlight their similitudes and/or differences about the motif of the soul’s birth.

On and off the stage at Atlanta Greek Picnic: Performances of collective black middle-class identities and the politics of belonging

This dissertation presents a thick ethnography that engages in the micro-analysis of the situationality of black middle-class collective identification processes through an examination of performances by members of the nine historically black sororities and fraternities at Atlanta Greek Picnic, an annual festival that occurs at the beginning of June in Atlanta, Georgia. It mainly attracts undergraduate and graduate members of these university-based organizations, as they exist all over the United States. This exploration of black Greek-letter organization (BGLO) performances uncovers processes through which young black middle-class individuals attempt to combine two universes that are at first glance in complete opposition to each other: the domain of the traditional black middle-class values with representations and fashions stemming from black popular culture. These constructions also attempt to incorporate—in a contradiction of sorts— black popular cultural elements in the objective to deconstruct the social conservatism that characterizes middle-class values, particularly in relation to sexuality and its representation in social behaviors and performances. This negotiation between prescribed v middle-class values of respectability and black popular culture provides a space wherein black individuals challenge and/or perpetuate those dominant tropes through identity performances that feed into the formation of black sexual politics, which I examine through a variety of BGLO staged and non-staged performances. ^

Inscape, the inshape of the trinity: a genetic analysis of Gerard Manley Hopkins’ "God’s Grandeur" and "The Windhover"

Les théories poétiques de l’inscape et du sprung rhythm établies par le poète britannique Gerard Manley Hopkins (1844-1889) ont dérouté les critiques des années durant. La plupart d’entre eux se sont appuyés sur les poèmes publiés en quête d’indices quant à la signification de ses théories. Cette thèse approfondit l’analyse mise de l’avant en révélant que la genèse de la théorie de l’inscape provient des notes de Hopkins — alors étudiant de premier cycle — sur le philosophe présocratique Parménide, et est influencée par les commentaires sur l’oeuvre De la nature du philosophe. Un examen des lettres de Hopkins à ses collègues poètes Robert Bridges et Richard Watson Dixon révèle que le sprung rhythm découle de l’inscape, sa théorie de base. La technique du sprung rhythm consiste donc en l’application de l’inscape au schéma métrique de la poésie. Cette étude établit d’abord une définition opérationnelle de chacune de ces théories pour ensuite les appliquer aux manuscrits afin de déterminer dans quelle mesure Hopkins y adhérait et les exploitait lors de la rédaction de deux de ses poèmes canoniques, God’s Grandeur et The Windhover. L’étude s’inscrit ainsi dans le champ de la critique génétique, une approche mise au point en France, particulièrement à l’Institut des textes et manuscrits modernes (ITEM). Ce sont donc sur des oeuvres littéraires françaises ou sur des textes en prose qu’ont porté la majorité des analyses à ce sujet. Suppressions, ajouts, substitutions et constantes entre différentes versions témoignent de ce qu’étaient les priorités de Hopkins dans sa quête pour atteindre l’effet désiré. Par conséquent, cette thèse s’efforce de dévoiler la signification des théories poétiques de Hopkins en établissant leur genèse et leur application respectives dans deux de ses poèmes selon une perspective de critique génétique. Elle contribue également à enrichir la critique génétique en l’appliquant à des oeuvres littéraires écrites en anglais et sous forme de poésie plutôt que de prose. Enfin, son objectif ultime est de raviver l’intérêt pour le poète Hopkins en tant que sujet viable d’étude, et de favoriser l’appréciation de ses prouesses tant comme théoricien poétique que comme poète.

Ageing and use of complex product interfaces

This paper presents an experiment designed to investigate if redundancy in an interface has any impact on the use of complex interfaces by older people and people with low prior-experience with technology. The important findings of this study were that older people (65+ years) completed the tasks on the Words only based interface faster than on Redundant (text and symbols) interface. The rest of the participants completed tasks significantly faster on the Redundant interface. From a cognitive processing perspective, sustained attention (one of the functions of Central Executive) has emerged as one of the important factors in completing tasks on complex interfaces faster and with fewer of errors.
