Sistema de control de garantías, actividades, dispositivos y de reporte de fallas y averías de los equipos de cómputo de la Procuraduría General de la República. [Tesis de Licenciatura]. Universidad Nacional, Costa Rica.En éste capítulo se procede a justificar el por qué es necesario crear un sistema automatizado para el control de garantías, actividades, dispositivos y de reportes de fallas y averías de los equipos de cómputo que permita brindar información cuantificable y estadística al Departamento de Informática de la Procuraduría General de la República, el cual se ha denominado con las siglas SIGETI. Se expone la situación actual de la Institución, así como una identificación del problema y se exponen los objetivos que se pretenden alcanzar con el desarrollo de la investigación. Posteriormente se demuestra, con razones específicas, los alcances y las limitaciones encontradas durante la investigación.This chapter proceeds to justify why it is necessary to create an automated system for the control of guarantees, activities, devices and reports of failures and breakdowns of computer equipment that allows providing quantifiable and statistical information to the Information Technology Department of the Office of the Attorney General of the Republic, which has been called with the acronym SIGETI. The current situation of the Institution is exposed, as well as an identification of the problem and the objectives that are intended to be achieved with the development of the investigation are exposed. Subsequently, the scope and limitations found during the investigation are demonstrated, with specific reasons.Universidad Nacional, Costa RicaEscuela de Informátic
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
