In situ monitoring and physical modelling of sub-glacial deformation at Skalafellsjokull
No full textThe controls on glacial movement remain one of the most poorly understood elements of the glacial system, largely due to the inaccessibility of the subglacial environment. Here a geotechnical study is presented that investigates the behaviour of till under pore pressure controlled decreases in normal effective stress. This is supplemented with field data from subglacial wireless probes, dGPS, GPR and a UAV survey of the glacial foreland to provide a broad view of subglacial deformation at Skalafellsjökull, IcelandThe geotechnical laboratory investigation was undertaken on till sampled from an ice marginal location at Skalafellsjökull, close to the probe deployment site. This showed that the till adhered to the Mohr-Coulomb model, behaving plastically. In addition, a back pressure shear box was used to model pore pressure controlled reductions in normal effective stress. Linearly reducing normal effective stress by increasing back pressure resulted in episodic increases in horizontal strain rates. Small reductions in shear stress resulted in large strain rate reductions but dilation hardening did not occur. Dilation hardening has previously been suggested as a causal factor in stick-slip glacial motion and a reason for the apparent scale dependence of till rheology, but these experiments suggest it may not be as significant as previously thought.High spatial variability was found throughout the field investigation in probe, dGPS and mapping data from the UAV survey. dGPS deployed above in situ subglacial probes recorded hourly ice movement indicative of stick-slip motion but it was not possible to link this motion to subglacial processes via probe data. Pore pressure data suggested spatially variable coupling to the subglacial hydrological system and inconsistent forcing by surface melt. Tilt data showed consistent movement patterns and lacked regular up-glacier movements previously thought to indicate ice-bed decoupling and sliding. The lack of evidence for forcing of velocity variability from the in situ data suggests a global forcing mechanism at this site, probably longitudinal or lateral coupling to higher velocity areas of the glacier. The spatial variability of the subglacial data has similarities to the metre scale spacing of flutes on the foreland mapped with the UAV imagery, suggesting flute formation has potential to result in complex probe behaviour
The author, the narrator : retelling the end of the “Vietnam War” in viet thanh nguyen’s The Sympathizer
Full text linkEste trabalho tem como objetivo analisar os papéis do autor e do narrador em O Simpatizante (2015), de Viet Thanh Nguyen, especialmente na releitura do fim da “Guerra do Vietnã” quarenta anos após a “Queda de Saigon”. Para tanto, este estudo examinará brevemente alguns dos trabalhos e discursos acadêmicos de Nguyen relacionados ao tema (e à sua vida), bem como analisará seu romance de estreia considerando os lugares do autor e do narrador. A conclusão é que o narrador, como parte do mundo representado na obra literária, e o autor, como parte do “mundo real” que participa da criação da obra literária, estão presentes em O Simpatizante. Ou seja, o narrador não oblitera o autor, mas é a sua voz - a voz do narrador - que se destaca no romance.This paper aims to analyze the roles of the author and the narrator in Viet Thanh Nguyen’s The Sympathizer (2015), especially in retelling the end of the “Vietnam War” forty years after the “Fall of Saigon”. For this purpose, this paper will briefly examine some of Nguyen’s academic works and speeches related to the topic (and to his life) and analyze his debut novel by considering the places of the author and the narrator. The conclusion is that the narrator, as part of the world represented in the literary work, and the author, as part of the “real world” that participates in the literary work’s creation, are present in The Sympathizer. That is, the narrator does not obliterate the author but it is his voice - the narrator’s voice - that stands out in the novel
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
