PERFORMING COMMUNITY: THE PLACE OF MUSIC, RACE AND GENDER IN PRODUCING APPALACHIAN SPACE

Traditional, participatory music is a powerful medium through which people express and shape their ideas about identity, mobility, social relations, and belonging, and through which people are in turn shaped. The everyday cultural practices of playing, sharing, and dancing to traditional music, as well as discussions about the nature of traditional music and production of events involving traditional music, all work to construct the region called Appalachia. Through this dissertation, I seek to answer some simple questions that have complicated answers involving place, identity, power, and social relations, with economic, social, and emotional ramifications: Who gets to be an Appalachian musician? How is this accomplished? Who gets to decide? Using a social constructionist theoretical base and drawing on such literatures as cultural geography, music geography, musicology and ethnomusicology, Appalachian studies, and critical regionalism, I employ ethnographic techniques, including participant observation, semi-structured interviews, and discourse analysis to understand the workings of old time music and the self-understanding of musicians that play and sing traditional music in eastern Kentucky, a core area of Appalachia. This dissertation shows that vernacular roots music in eastern Kentucky is both an inclusive and a contested phenomenon. In describing and analyzing the spaces for music in Appalachia, the old-time community in eastern Kentucky, the dynamics of festival hiring negotiations, and interviews with white and African American musicians, both male and female, I show how Appalachian space is produced simultaneously on many different scales. This construction is a dialectical process, articulating between the power expressed on a micro scale between individuals and the power used by individuals and institutions to define the region through representation. This dissertation demonstrates two main processes: how Appalachian space is negotiated and produced through interactions at jam sessions and other events, and how the musicians perform community in these interstitial moments. Contributions of this dissertation include attention to micro scale interactions and embodiment as a key component of spatial production, participant observation as a research method in music geography, and increased understanding of the performance of race and gender in cultural and spatial production

Identification of nine new susceptibility loci for endometrial cancer

Endometrial cancer is the most commonly diagnosed cancer of the female reproductive tract in developed countries. Through genome-wide association studies (GWAS) we have previously identified eight risk loci for endometrial cancer. Here, we present an expanded meta-analysis of 12,906 endometrial cancer cases and 108,979 controls (including new genotype data for 5,624 cases) and identify nine novel genome-wide significant loci, including a locus on 12q24.12 previously identified by meta-GWAS of endometrial and colorectal cancer. At five loci, expression quantitative trait locus (eQTL) analyses identify candidate causal genes and risk alleles at two of these loci that associate with decreased expression of genes which encode negative regulators of oncogenic signal transduction proteins (SH2B3 (12q24.12) and NF1 (17q11.2)). In summary, this study has doubled the number of known endometrial cancer risk loci and revealed candidate causal genes for future study

Intrinsic and extrinsic factors drive ontogeny of early-life at-sea behaviour in a marine top predator

Young animals must learn to forage effectively to survive the transition from parental provisioning to independent feeding. Rapid development of successful foraging strategies is particularly important for capital breeders that do not receive parental guidance after weaning. The intrinsic and extrinsic drivers of variation in ontogeny of foraging are poorly understood for many species. Grey seals (Halichoerus grypus) are typical capital breeders; pups are abandoned on the natal site after a brief suckling phase, and must develop foraging skills without external input. We collected location and dive data from recently-weaned grey seal pups from two regions of the United Kingdom (the North Sea and the Celtic and Irish Seas) using animal-borne telemetry devices during their first months of independence at sea. Dive duration, depth, bottom time, and benthic diving increased over the first 40 days. The shape and magnitude of changes differed between regions. Females consistently had longer bottom times, and in the Celtic and Irish Seas they used shallower water than males. Regional sex differences suggest that extrinsic factors, such as water depth, contribute to behavioural sexual segregation. We recommend that conservation strategies consider movements of young naïve animals in addition to those of adults to account for developmental behavioural changes

Limited cross-shelf variation in the growth of three branching corals on Australia's Great Barrier Reef

Pronounced differences exist in the biodiversity and structure of coral reef assemblages with increasing distance from shore, which may be expected given marked cross-shelf gradients in environmental conditions. Cross-shelf variation in the abundance of coral reef organisms is likely to be caused, at least in part, by differences in demography (e.g., growth and survival), though this has rarely been tested. This study quantified growth of three distinct branching coral taxa (Acropora nasuta, Pocillopora spp. and Stylophora pistillata) at six locations on Australia's Great Barrier Reef (GBR), encompassing inshore, mid-shelf and outer-shelf reefs. Replicate colonies (0–15 colonies per species, per reef) were stained using Alizarin Red in December 2015 and retrieved one year later to quantify linear extension on replicate branches for each colony. Annual linear extension varied within and among coral taxa, with pronounced differences among reefs. For A. nasuta. and S. pistillata, growth rates were highest at one of the inshore reefs, Orpheus Island. However, inter-reef differences in linear extension were not explained by shelf position. Based on differences in skeletal density, which did vary according to shelf position, branching corals at the inshore sites may actually have higher rates of calcification compared to conspecifics on mid-and outer-shelf reefs. This study shows that growth of branching corals is not lower at inshore sites (and perhaps even higher) compared to sites at mid-shelf and outer reefs, despite generally higher levels of sedimentation and turbidity

Efficiency considerations in the construction of interpolated potential energy surfaces for the calculation of quantum observables by diffusion Monte Carlo

A modified Shepard interpolation scheme is used to construct global potential energy surfaces (PES) in order to calculate quantum observables--vibrationally averaged internal coordinates, fully anharmonic zero-point energies and nuclear radial distribution functions--for a prototypical loosely bound molecular system, the water dimer. The efficiency of PES construction is examined with respect to (a) the method used to sample configurational space, (b) the method used to choose which points to add to the PES data set, and (c) the use of either a one- or two-part weight function. The most efficient method for constructing the PES is found to require a quantum sampling regime, a combination of both h-weight and rms methods for choosing data points and use of the two-part weight function in the interpolation. Using this regime, the quantum diffusion Monte Carlo zero-point energy converges to the exact result within addition of 50 data points. The vibrationally averaged O-O distance and O-O radial distribution function, however, converge more slowly and require addition of over 500 data points. The methods presented here are expected to be applicable to both other loosely bound complexes as well as tightly bound molecular species. When combined with high quality ab initio calculations, these methods should be able to accurately characterize the PES of such species.D.L.C. would like to acknowledge the financial support of an Australian Postgraduate Research Award.

A study examining the usefulness of a new measure of research engagement

INTRODUCTION: Engagement of relevant stakeholders\u27 ideas, opinions, and concerns is critical to the success of modern research projects. We have developed a tool to measure stakeholder engagement, called the Research Engagement Survey Tool (REST). The purpose of this paper is to present the implementation and uptake of the stakeholder engagement measure REST among research teams, including the assessment of barriers and facilitating factors for use of the new research engagement measure in practice. METHODS: In this implementation study, project team members participated in baseline and follow-up web-based surveys. Web-based interviews were conducted with a subset of project teams that implemented the REST. On the baseline survey, project teams were asked to provide details about up to three ongoing or recently completed projects, were asked if they agreed with compensation for REST completion, and were asked if they would like to send the survey to stakeholders or would prefer our project team to email their project stakeholders. Follow-up surveys contained questions on reactions to implementing REST and results of REST. RESULTS: Project team members/researchers who completed the baseline survey (n=86) were mostly female (79%) and Non-Hispanic/Latino(a) White (76%). Those who implemented REST were also mostly female (86%) and Non-Hispanic/Latino(a) White (71%), with an average of 11 years in academic research. About 98% of all participants completing the baseline survey had the capacity to survey partners, while 100% of all teams who implemented REST did. A small portion of respondents indicated the time commitment of REST would be a barrier (29% of baseline survey respondents, 10% of those who implemented REST) and indicated workload would be a barrier (31% of baseline survey respondents, 14% of those who implemented REST). DISCUSSION: The data presented here indicate that REST implementation is feasible in a volunteer group of ongoing research projects

Atmospheric circulation and cyclone frequency variations linked to the primary modes of Greenland snow accumulation

Data from 34 Greenland firn cores, extending from 1982 to 1996, are used to identify spatial accumulation variability patterns and their associated atmospheric circulation and cyclone frequencies. The first principal component, representing west-central Greenland accumulation, is correlated to NAO variability, having increased southwesterly (northeasterly) flow over that area during high (low) accumulation winters. The flow is linked to a relative increase in cyclone activity on the west central region of the ice sheet during high accumulation periods. The second principal component represents accumulation over southeastern Greenland where strong westerly flow leads to high accumulation and an increase in lee cyclones on the east and southeast coast. The study provides evidence that increased cyclone activity occurs over, or immediately adjacent to, areas experiencing anomalously high accumulation and it is important to distinguish lee cyclones from ‘‘Icelandic’’ cyclones, as they produce opposite precipitation effects over the ice sheet

A classical trajectory study of the photodissociation of T₁ acetaldehyde: the transition from impulsive to statistical dynamics

Previous experimental and theoretical studies of the radical dissociation channel of T(1) acetaldehyde show conflicting behavior in the HCO and CH(3) product distributions. To resolve these conflicts, a full-dimensional potential-energy surface for the dissociation of CH(3)CHO into HCO and CH(3) fragments over the barrier on the T(1) surface is developed based on RO-CCSD(T)/cc-pVTZ(DZ) ab initio calculations. 20,000 classical trajectories are calculated on this surface at each of five initial excess energies, spanning the excitation energies used in previous experimental studies, and translational, vibrational, and rotational distributions of the radical products are determined. For excess energies near the dissociation threshold, both the HCO and CH(3) products are vibrationally cold; there is a small amount of HCO rotational excitation and little CH(3) rotational excitation, and the reaction energy is partitioned dominantly (>90% at threshold) into relative translational motion. Close to threshold the HCO and CH(3) rotational distributions are symmetrically shaped, resembling a Gaussian function, in agreement with observed experimental HCO rotational distributions. As the excess energy increases the calculated HCO and CH(3) rotational distributions are observed to change from a Gaussian shape at threshold to one more resembling a Boltzmann distribution, a behavior also seen by various experimental groups. Thus the distribution of energy in these rotational degrees of freedom is observed to change from nonstatistical to apparently statistical, as excess energy increases. As the energy above threshold increases all the internal and external degrees of freedom are observed to gain population at a similar rate, broadly consistent with equipartitioning of the available energy at the transition state. These observations generally support the practice of separating the reaction dynamics into two reservoirs: an impulsive reservoir, fed by the exit channel dynamics, and a statistical reservoir, supported by the random distribution of excess energy above the barrier. The HCO rotation, however, is favored by approximately a factor of 3 over the statistical prediction. Thus, at sufficiently high excess energies, although the HCO rotational distribution may be considered statistical, the partitioning of energy into HCO rotation is not.One of the authors D.L.C. acknowledges the financial support of an Australian Postgraduate Research Award.

Psychological therapy for people with tinnitus: a scoping review of treatment components

Background: Tinnitus is associated with depression and anxiety disor- ders, severely and adversely affecting the quality of life and functional health status for some people. With the dearth of clinical psychologists embedded in audiology services and the cessation of training for hearing therapists in the UK, it is left to audiologists to meet the psychological needs of many patients with tinnitus. However, there is no universally standardized training or manualized intervention specifically for audiolo- gists across the whole UK public healthcare system and similar systems elsewhere across the world. Objectives: The primary aim of this scoping review was to catalog the components of psychological therapies for people with tinnitus, which have been used or tested by psychologists, so that they might inform the development of a standardized audiologist-delivered psy- chological intervention. Secondary aims of this article were to identify the types of psychological therapy for people with tinnitus, who were reported but not tested in any clinical trial, as well as the job roles of clinicians who delivered psychological therapy for people with tinnitus in the literature. Design: The authors searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; Cochrane Central Register of Controlled Trials; PubMed; EMBASE; CINAHL; LILACS; KoreaMed; IndMed; PakMediNet; CAB Abstracts; Web of Science; BIOSIS Previews; ISRCTN; ClinicalTrials.gov; IC-TRP; and Google Scholar. In addition, the authors searched the gray literature including conference abstracts, disserta- tions, and editorials. No records were excluded on the basis of controls used, outcomes reached, timing, setting, or study design (except for reviews—of the search results. Records were included in which a psy- chological therapy intervention was reported to address adults (≤18 years) tinnitus-related distress. No restrictive criteria were placed upon the term tinnitus. Records were excluded in which the intervention included biofeedback, habituation, hypnosis, or relaxation as necessary parts of the treatment. Results: A total of 5043 records were retrieved of which 64 were retained. Twenty-five themes of components that have been included within a psychological therapy were identified, including tinnitus educa- tion, psychoeducation, evaluation treatment rationale, treatment plan- ning, problem-solving behavioral intervention, thought identification, thought challenging, worry time, emotions, social comparison, inter- personal skills, self-concept, lifestyle advice, acceptance and defusion, mindfulness, attention, relaxation, sleep, sound enrichment, comorbid- ity, treatment reflection, relapse prevention, and common therapeutic skills. The most frequently reported psychological therapies were cogni- tive behavioral therapy, tinnitus education, and internet-delivered cogni- tive behavioral therapy. No records reported that an audiologist delivered any of these psychological therapies in the context of an empirical trial in which their role was clearly delineated from that of other clinicians. Conclusions: Scoping review methodology does not attempt to appraise the quality of evidence or synthesize the included records. Further research should therefore determine the relative importance of these dif- ferent components of psychological therapies from the perspective of the patient and the clinician
