An Omnivorous Ear: The Creative Practice of Field Recording

“An Omnivorous Ear - The Creative Practice of Field Recording” offers new insights into the history of recording outside of the studio in North America, challenging the various working definitions of field recording in music studies, anthropology, and communications. I examine recording methodologies through the late 19th and 20th centuries as a documentary technique, a tool for composition, and an art object in the United States of America and Canada from the late 19th century to the present day. Within this geographical region, I focus on the invention of acoustic recording, the proliferation of the technology amongst the public, folkloric recording supported by governmental and academic institutions, as well a experimental artistic practices. Throughout the dissertation, I argue that ‘the field’ is a social construction mediated by the recordist and recorder. Chapter 2 focuses on how cultures translate collective and phenomenological experiences into histories through sound media. These include orality, writing, the inscription of sound waves onto media, acoustic recording, and radio as forms of sound media that each embodies distinct forms of social and political knowledge. Chapter 3 details the development of recording machines and their effect on listening practices. Chapter 4 locates practitioners of phonography within the development of portable recording equipment on the one hand and the ‘hi-fi’ cultural movement in North America on the other. Practitioners included folklorists Alan Lomax from the Library of Congress, Moses Asch of Folkways Records, and Harry Smith, creator of the Anthology of American Folk Music; Stefan Kudelski, creator of the NAGRA recorder; and media maker Tony Schwartz, among the first to create the sound documentary by editing field recordings. Chapter 5 explores the relationship between sound, music and the environment within the paradigm of the soundscape as theorized by the World Soundscape Project (WSP). I critique the research and compositional practices developed by WSP members, and the influence it has on ecomusicology and sound art. Chapter 6 outlines sonic ethnography, a methodology that borrows from the best practices of many of the individuals mentioned throughout the dissertation, and employs new compositional techniques to condense and manipulate social, political and historical narratives through sonic works. The dissertation concludes by arguing that field recording, can be used to critique aesthetic and cultural dilemmas of representation.Cambridge Overseas Trus

Identifying Overlapping and Hierarchical Thematic Structures in Networks of Scholarly Papers: A Comparison of Three Approaches

We implemented three recently proposed approaches to the identification of overlapping and hierarchical substructures in graphs and applied the corresponding algorithms to a network of 492 information-science papers coupled via their cited sources. The thematic substructures obtained and overlaps produced by the three hierarchical cluster algorithms were compared to a content-based categorisation, which we based on the interpretation of titles and keywords. We defined sets of papers dealing with three topics located on different levels of aggregation: h-index, webometrics, and bibliometrics. We identified these topics with branches in the dendrograms produced by the three cluster algorithms and compared the overlapping topics they detected with one another and with the three pre-defined paper sets. We discuss the advantages and drawbacks of applying the three approaches to paper networks in research fields.Comment: 18 pages, 9 figure

Attack Resilience of the Evolving Scientific Collaboration Network

Stationary complex networks have been extensively studied in the last ten years. However, many natural systems are known to be continuously evolving at the local (“microscopic”) level. Understanding the response to targeted attacks of an evolving network may shed light on both how to design robust systems and finding effective attack strategies. In this paper we study empirically the response to targeted attacks of the scientific collaboration networks. First we show that scientific collaboration network is a complex system which evolves intensively at the local level – fewer than 20% of scientific collaborations last more than one year. Then, we investigate the impact of the sudden death of eminent scientists on the evolution of the collaboration networks of their former collaborators. We observe in particular that the sudden death, which is equivalent to the removal of the center of the egocentric network of the eminent scientist, does not affect the topological evolution of the residual network. Nonetheless, removal of the eminent hub node is exactly the strategy one would adopt for an effective targeted attack on a stationary network. Hence, we use this evolving collaboration network as an experimental model for attack on an evolving complex network. We find that such attacks are ineffectual, and infer that the scientific collaboration network is the trace of knowledge propagation on a larger underlying social network. The redundancy of the underlying structure in fact acts as a protection mechanism against such network attacks

Advances in Molecular Quantum Chemistry Contained in the Q-Chem 4 Program Package

A summary of the technical advances that are incorporated in the fourth major release of the Q-Chem quantum chemistry program is provided, covering approximately the last seven years. These include developments in density functional theory methods and algorithms, nuclear magnetic resonance (NMR) property evaluation, coupled cluster and perturbation theories, methods for electronically excited and open-shell species, tools for treating extended environments, algorithms for walking on potential surfaces, analysis tools, energy and electron transfer modelling, parallel computing capabilities, and graphical user interfaces. In addition, a selection of example case studies that illustrate these capabilities is given. These include extensive benchmarks of the comparative accuracy of modern density functionals for bonded and non-bonded interactions, tests of attenuated second order Møller–Plesset (MP2) methods for intermolecular interactions, a variety of parallel performance benchmarks, and tests of the accuracy of implicit solvation models. Some specific chemical examples include calculations on the strongly correlated Cr2 dimer, exploring zeolite-catalysed ethane dehydrogenation, energy decomposition analysis of a charged ter-molecular complex arising from glycerol photoionisation, and natural transition orbitals for a Frenkel exciton state in a nine-unit model of a self-assembling nanotube

Determinants of penetrance and variable expressivity in monogenic metabolic conditions across 77,184 exomes

Penetrance of variants in monogenic disease and clinical utility of common polygenic variation has not been well explored on a large-scale. Here, the authors use exome sequencing data from 77,184 individuals to generate penetrance estimates and assess the utility of polygenic variation in risk prediction of monogenic variants

Social distance between local residents and African-American expatriates in the context of Ghana's slavery-based heritage tourism

This paper explores the social distance between local residents and African-Americans who have settled in Ghana since the 1960s. Data generated from in-depth interviews suggest the African-American expatriates felt their proximity to collective slave memory or particularly slavery heritage conferred on them certain rights to exclude local residents who are more susceptible to forgetting the past. By appropriating traces of the past, the African-American expatriates provide a range of tourism services, albeit to visitors they believed subscribed to socially constructed meanings elicited at slave sites. The study suggests explicit recognition of African-American expatriates in the levels of contestations that result from slavery-based heritage tourism

Software for the frontiers of quantum chemistry:An overview of developments in the Q-Chem 5 package

This article summarizes technical advances contained in the fifth major release of the Q-Chem quantum chemistry program package, covering developments since 2015. A comprehensive library of exchange–correlation functionals, along with a suite of correlated many-body methods, continues to be a hallmark of the Q-Chem software. The many-body methods include novel variants of both coupled-cluster and configuration-interaction approaches along with methods based on the algebraic diagrammatic construction and variational reduced density-matrix methods. Methods highlighted in Q-Chem 5 include a suite of tools for modeling core-level spectroscopy, methods for describing metastable resonances, methods for computing vibronic spectra, the nuclear–electronic orbital method, and several different energy decomposition analysis techniques. High-performance capabilities including multithreaded parallelism and support for calculations on graphics processing units are described. Q-Chem boasts a community of well over 100 active academic developers, and the continuing evolution of the software is supported by an “open teamware” model and an increasingly modular design

Genome-Wide Association Study in BRCA1 Mutation Carriers Identifies Novel Loci Associated with Breast and Ovarian Cancer Risk

BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7×10-8, HR = 1.14, 95% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4×10-8, HR = 1.27, 95% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4×10-8, HR = 1.20, 95% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific associat
