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
Evaluation of Residual Stresses by Microscale FIB-DIC Ring-Core Milling and Other Techniques for Beam Dump Application at CERN
No full textIn the framework of the CERN R\&D activities for the Beam Dump Facility (BDF), different target prototypes were fabricated. They are cylinders made of refractory metals, clad with a tantalum layer by means of Hot Isostatic Pressing (HIP). High residual stresses resulting from the HIP cycle are expected and its assessment is indispensable to validate the targets thermo-mechanical simulations. Techniques such as hole drilling, X-ray diffraction and microscale Focused Ion Beam (FIB) ring-core milling followed Digital Image Correlation (DIC) analysis were employed to determine and understand the residual stress distribution in those parts. The presented Master's thesis has been developed at CERN Engineering department (EN), in the Materials and Metrology group (MME) under the direct supervision of Josep Busom Descarrega (CERN) Ana Teresa Pérez Fontenla (CERN) and Raino Mikael Larsen (Aalborg University)
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
Space instrumentation environmental verification: Dynamic Test on GLAST LAT tracker trays
Full text linkThe GLAST satellite is a mission for the detection of gamma rays of both galactic and extra-galactic origin in the energy range 20 keV-300 GeV. The satellite is planned to be launched in 2007 by NASA. Gamma rays detection is based on the pair conversion mechanism achieved by a multilayer silicon strip detector interleaved with a tungsten target for photon conversion and e(+)-e(-) pairs tracking. The GLAST program did foresee a wide use of vibration tests both in development and in qualification phases. The acceptance phase in aerospace environment is usually demanding in terms of vibration tests. Furthermore in this program the trays' design and manufacturing procedure might have been highly vibration sensitive, and experimental validation was considered highly recommendable. This paper aims to give evidence of the performed tests. A critical analysis of the tests is proposed and some results will be also presented. (c) 2006 Published by Elsevier B.V
Escuela infantil como espacio de co-formación. Análisis entre el Instituto Superior de Fomación Docente N°8 y las escuelas infantiles de Junín de los Andes (Neuquén)
Full text linkLa presente investigación tiene como objetivo analizar y caracterizar la articulación entre el Instituto Superior de Formación Docente y las Escuelas Infantiles desde los lineamientos curriculares vigentes y las prácticas pedagógicas situadas, para pensar la formación académica, dentro de la escuela infantil desde una perspectiva co-formativa, para los futuros profesionales de Educación Inicial. La problemática se presenta desde varios tópicos: por un lado los lineamientos curriculares vigentes en la provincia, por el otro las prácticas situadas en lugares formales y no formales, y un tercer tópico la escuela infantil como una nueva organización institucional en la provincia. El propósito de este estudio basado en teoría fundamentada de ruta cualitativa, tiene como objetivo analizar la problemática territorial. Cómo instrumento de recolección de información se diseña un cuestionario semi estructurado y narrativas, de carácter anónimo, cuya población encuestada encuadra docentes, equipos de conducción, supervisores y profesores del ISFD, a fin de dar cuenta del trabajo territorial. El fin de esta investigación es brindar un acercamiento lo más situado posible, para contextualizar la realidad educativa en la que está inmersa la provincia de Neuquén, y así poder visualizar el trabajo territorial de la localidad de Junín de los Andes.Fil: Raino, Mariana.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
