Partial Database Replication and Group Communication Primitives (Extended Abstract)
No full text) Gustavo Alonso Database research Group Institute for Information Systems ETH Zentrum, Zurich CH-8092, Switzerland E-mail: [email protected] January 17, 1997 1 Introduction Existing research on replication is generally based on synchronous replication (all copies are kept consistent at all times) and update everywhere (any replica can be updated) approaches. There is a strong belief among database designers, however, that synchronous, update everywhere replication is simply not feasible in a database environment [GBH + 96, Gol94, Sta94]. Some of the arguments behind this belief is the high probability of deadlocks that replication introduces and the problems to scale any replication approach beyond a few sites. As a result, most current database replication solutions are asynchronous (copies are not kept consistent at all times) and based on a primary-copy approach 1 (only one master copy can be updated, all other replicas are read-only) [Gol94, Sta94]. An additional argument..
Memorias del conflicto armado a través de relatos biográficos de la vida de Gustavo Alonso Gaviria Restrepo
No full textRESUMEN: Con la realización de este trabajo de grado “Memorias del conflicto armado a través de relatos
biográficos de la vida de Gustavo Alonso Gaviria Restrepo”, se pretende dar a conocer la
importancia que desde el campo de la disciplina Archivística se da a los testimonios (relatos y
documentos de archivo) que contienen información de vital importancia y que dan sentido e
identidad en los procesos de construcción de memoria, especialmente los realizados a familias
colombianas que han sido víctimas del conflicto armado.
El enfoque de esta investigación fue de carácter cualitativo, por lo que, su metodología estuvo
apoyada en técnicas e instrumentos de investigación que permitieron la realización de
investigaciones documentales, fichas bibliográficas, una cartografía, entrevistas
semiestructuras y un cuestionario guía, lo cual fue fundamental para activar la memoria de
aquellos recuerdos que permitieron construir una memoria familiar. El resultado de este
proceso fueron unos relatos biográficos que permitieron construir una memoria familiar basada
en testimonios y documentos de archivo, sobre la vida y muerte de Gustavo Alonso Gaviria
Restrepo en tiempo del conflicto armado, además, un dispositivo de memoria que será
compartido a la familia, con el fin de ser preservado y presentado a las futuras generaciones
que formarán parte de la familia Gaviria Restrepo.
Las conclusiones resaltan la importancia del papel que desempeñan los testimonios y
documentos de archivo como contribución y fuente de verdad en los procesos de construcción
de memoria. Además, se habla de los aprendizajes y experiencias vividas durante esta
investigación desde la voz de Margarita Gaviria Restrepo (mi madre) quien estuvo presente en
todo este proceso de investigación.ABSTRACT: With the realization of this degree work "Memories of the armed conflict through biographical
accounts of the life of Gustavo Alonso Gaviria Restrepo", it is intended to make known the
importance that from the field of the archival discipline is given to the testimonies (stories and
archival documents) that contain vital information and that give meaning and identity in the
processes of memory construction, especially those made to Colombian families who have
been victims of the armed conflict.
The approach of this research was qualitative, therefore, its methodology was supported by
research techniques and instruments that allowed the realization of documentary research,
bibliographic records, a mapping, semi-structured interviews and a questionnaire guide, which
was essential to activate the memory of those memories that allowed the construction of a
family memory. The result of this process were biographical accounts that allowed the
construction of a family memory based on testimonies and archival documents, about the life
and death of Gustavo Alonso Gaviria Restrepo during the armed conflict, as well as a memory
device that will be shared with the family, in order to be preserved and presented to future
generations that will be part of the Gaviria Restrepo family.
The conclusions highlight the importance of the role played by testimonies and archival
documents as a contribution and source of truth in the processes of memory construction. In
addition, it talks about the lessons learned and experiences lived during this research from the
voice of Margarita Gaviria Restrepo (my mother) who was present throughout this research
process.En el presente trabajo de grado, se presentan dos links de la plataforma genially, a los cuáles el lector podrá acceder siempre y cuando cuente con conexión a internet; éstos links corresponden en primer lugar, a una cartografía realizada con el fin de identificar el espacio geográfico en el que suceden los hechos, y en segundo lugar al dispositivo de memoria que recopila la historia de vida de Gustavo Alonso Gaviria Restrepo.PregradoArchivist
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

No full textDispelling 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
