COASTAL MAPPING OF JINU-DO WITH UAV FOR BUSAN SMART CITY, KOREA
Get PDFFor illustrating estuarine and coastal morphology, UAV has proved its effectiveness in providing accurate and diverse information, but unfortunately, no such application have been undertaken for Nakdong River Estuary for ecosystem-based coastal mapping. In this study an attempt has been made to coastal mapping of Jinu-do in Nakdong River Estuary, and to identify beach volume change and vegetation area migration caused by wave and current from 2017 to 2018 with UAV. Unmanned aerial vehicle used for mapping was M600 hexa-copter drone (DJI, china). To create UAV point clouds a standard digital camera can provide imagery with Sony A7 mirror-less camera. Total 34 Ground Control Points (GCPs) accurately surveyed with a RTK-VRS, network use real-time kinematic solutions to provide high-accuracy. Stereo-matching using Agisoft PhotoScan obtained DEM. Using GCPS the vertical accuracy of the DSMs were found to be 5 cm or better. Using the PhotoScan, the area of Jinu-do orthophotos were calculated and the area of vegetation calculated using QGIS. As a result, the vegetation area was increased about 5 % more than the topography. This study of coastal mapping at Jinu-do demonstrate that the integration of UAV techniques and photogrammetric software and analysis tools can provide new concepts into the estuarine

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Jinu Potó, ¿Mito o historia? Desplazamientos del saber y cuestionamientos epistémicos en la narración oral del pueblo Embera Dóbida
Get PDFEl presente artículo pretende aportar una reflexión en el ámbito de las metodologías de estudio acerca de las formas contemporáneas de la narración oral, en el contexto de la producción mitopoiética embera dóbida en el Pacífico colombiano. El análisis compa-ra dos narraciones orales del relato fundacional de Jinu Potó, realizadas por un joven miembro de la comunidad embera dóbida de Boca de Jagua y por un mayor pertene-ciente a la comunidad embera dóbida de Yucal, ambas ubicadas en el departamento del Chocó (Colombia). El artículo entreteje un estudio de los motivos narrativos (motife-mas) del relato con un análisis de ‘lo que acontece entre’ la narración. Según la tesis pro-puesta, lo que acontece entre la narración integra la misma dimensión epistemológica de la producción oraliteraria embera y condensa huellas y trayectorias del proceso futural de reconfiguración epistémica en curso en distintas culturas indígenas colombianas con-temporáneas, particularmente en contextos de desplazamiento forzado.This essay aims to provide a reflection in the field of analysis methodologies about con-temporary forms of oral narration, in the context of embera dóbida mythopoietic pro-duction in the Colombian Pacific region. The analysis compares two oral narrations of the cosmogonical story of Jinu Potó, made by a young member of the embera Dóbida community of Boca de Jagua and by an older member of the embera Dóbida community of Yucal, both located in the Department of Chocó (Colombia). The article interweaves a study of the narrative motifs (motifemes) of the story with an analysis of ‘what happens between’ the narrative. According to the proposed thesis, what happens between the narration integrates the epistemological dimension of the embera oraliterary production and condenses traces and trajectories of the contemporary futural process of epistemic reconfiguration in different colombian indigenous cultures, particularly in contexts of forced displacement
Variations on the Author
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
