Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Anatomical suitability for branched endovascular aortic arch repair and balloon-expandable bridging stent grafts in a cohort of patients previously treated with a hybrid approach
No full textObjective: We assessed the suitability of two triple branch arch devices (aBranch) (Terumo aortic and Cook Medical) and a balloon-expandable covered stent (VBX, W. L. Gore & Associates, Johnson & Johnson) to incorporate the brachiocephalic trunk (BCT) in a cohort previously treated with hybrid thoracic endovascular repair (TEVAR). Methods: This is a single-center, retrospective, all-comers, preclinical suitability study. We conducted an analysis of preoperative computed tomography scans in surgical patients between 1999 and 2022 in a single vascular surgery unit. The primary outcome was the aortic suitability of aBranch devices and VBX as mating stent for BCT in previous hybrid TEVAR. Hybrid repair of the aortic arch included TEVAR, fenestrated or branched TEVAR associated with any surgical debranching of the supra-aortic trunks and chimney TEVAR with proximal landing in zones 0 to 2. Secondary outcomes included (i) suitability assessment when excluding minor instruction for use (IFU) criteria, (ii) a comparison of suitable and nonsuitable patients, (iii) risk factors analysis for nonsuitability, and (iv) a description of the exclusion causes. Results: During the study period, 120 patients were treated. Among elective patients (n = 73), the suitability of any aBranch was 82.2% (60/73) and VBX was suitable in 64.4% of BCTs (47/73). The aBranch suitable patients had a significantly longer sinotubular-BCT length (P = .017) and smaller distal ascending aorta (P = .043) as compared with nonsuitable ones. The suitability of Terumo Aortic and Cook Medical devices was 52.1% (38/73) and 46.6% (34/73), respectively. When minor IFU criteria were ignored, suitability increased to 82.2% (60/73) and 63.0% (46/73), respectively. Left common carotid artery diameter and sinotubular-BCT length were significant nonsuitability risk factors for Terumo Aortic aBranch in multivariable analysis. No associations were found for Cook Medical device. The outcomes were tested in the entire cohort demonstrating a global suitability of 82.9%, increasing to 86.3% when ignoring minor IFUs. VBX was anatomically suitable to use in BCT in 73.2% of patient BCTs. Conclusions: aBranch devices are anatomically suitable in a vast majority of patients (86%) undergoing hybrid TEVAR. The innominate artery seems eligible for incorporation with VBX in almost two-thirds of patients. This mating stent may help to overcome some minor IFU restrictions
Evaluating Research Impact through Open Access to Scholarly Communication
No full textScientific research is a competitive business – in order to secure funding, promotion and tenure researchers must demonstrate their work has impact in their field. To maximise impact researchers undertake high priority research, aim to get results first, and publish in the highest impact journals. The Internet now presents a new opportunity to the scholarly author seeking higher impact: s/he can now make their work instantly accessible on the Web through author self-archiving. This growing body of open access literature (coupled with new publishing models that make journals available for-free to the reader) maximises research impact by maximising the number of people who can read it, and making it available sooner. Open access also provides a new opportunity for bibliometric research. This thesis describes the relatively recent phenomenon of open access to research literature, tools that were built to collect and analyse that literature, and the results of analyses of the effect of open access and its effect on author behaviour. It shows that articles self-archived by authors receive between 50-250% more citations, that rapid pre-printing on the Web has dramatically reduced the peak citation rate from over a year to virtually instant and how citation-impact – now widely used for evaluation – can be expanded to include a new web metric of download impact

The Gospel on the Margins: The Ideological Function of the Patristic Tradition on the Evangelist Mark
No full textIn spite of the virtually unanimous patristic opinion that the evangelist Mark was the interpreter of Peter, one of the most prestigious apostolic founding figures in Christian memory, the Gospel of Mark was mostly neglected in the patristic period. Not only is the text of Mark the least well represented of the canonical Gospels in terms of the number of patristic citations, commentaries and manuscripts, the explicit comments about the evangelist Mark reveal some ambivalence about its literary or theological value. In my survey of the reception of Mark from Papias of Hierapolis until Clement of Alexandria, I will argue that the reason why the patristic writers were hesitant to embrace the Gospel of Mark was that they perceived the text to be amenable to the Christological beliefs and social praxis of rival Christian factions. The patristic tradition about Mark may have little historical basis, but it had an important ideological function in appropriating the text in the name of an apostolic authority from the margins or periphery
Genetic association study of QT interval highlights role for calcium signaling pathways in myocardial repolarization.
No full textThe QT interval, an electrocardiographic measure reflecting myocardial repolarization, is a heritable trait. QT prolongation is a risk factor for ventricular arrhythmias and sudden cardiac death (SCD) and could indicate the presence of the potentially lethal mendelian long-QT syndrome (LQTS). Using a genome-wide association and replication study in up to 100,000 individuals, we identified 35 common variant loci associated with QT interval that collectively explain ∼8-10% of QT-interval variation and highlight the importance of calcium regulation in myocardial repolarization. Rare variant analysis of 6 new QT interval-associated loci in 298 unrelated probands with LQTS identified coding variants not found in controls but of uncertain causality and therefore requiring validation. Several newly identified loci encode proteins that physically interact with other recognized repolarization proteins. Our integration of common variant association, expression and orthogonal protein-protein interaction screens provides new insights into cardiac electrophysiology and identifies new candidate genes for ventricular arrhythmias, LQTS and SCD
Photography as an agent of architectural proposition and provocation
No full textThe advent of photography provided scientists with new tools to reveal aspects of the physical world that had not been perceived before. Photography provided a degree of veracity that suited scientific inquiry and this authority also made photography the medium of choice for proposing speculative phenomena such as phantasms. Since at least Leonardo, painters have adjusted the picture plane to make their paintings appear more true to life. In natural history dioramas the painted surface is curved to engage our peripheral vision. The chapter discusses the potential of photography as a propositional medium for architects and describes a set of cameras built by the author to replicate the projective geometry of one of James Perry Wilson’s dioramas at the Yale Peabody Museum. Learning from these cameras, the author builds a drawing instrument that has a folding picture plane (that registers photographically) to allow the person drawing with it to appropriate projected material (a physical model also by the author). The aim of this work is to use photography as a propositional medium to discuss indeterminate conditions in architecture
Pixelated Abstraction
No full textPixel art remains a contemporary art form and a common rendering technique in digital games and media. However, the manual creation of pixel art is often time consuming and requires a degree of skill that is not easily obtained by novices of the art. Few, if any, methods exist to automatically generate pixel art. Naive downsampling tech-niques such as nearest neighbor and cubic downsampling do not adequately preserve features or maintain a vibrant palette. In this thesis we present our work on automat-ically and semi-automatically converting high resolution images into an output that approximates the manual results of pixel artists. This is a multi-step, iterative algo-rithm that simultaneously solves for a palette and a mapping of segments of the input image to pixels in the output. We provide a set of controls that give the user flexible influence on the output and the ability to work anywhere between a purely automated and purely manual process. We present the automated and semi-automated results of our algorithm and compare them to the results generated using naive downsampling techniques and the manual results produced by expert pixel artists. Through a formal user study and interviews with expert pixel artists, we demonstrate that our result
