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
Successful Latin American initiatives in biophysics
Get PDFThe Latin American Federation of Biophysical Societies (LAFeBS) was founded in 2007 to encourage the development and dissemination of knowledge in biophysics. The Federation comprises biophysical societies and groups of researchers from the following countries: Argentina, Brazil, Colombia, Portugal, Spain, Uruguay, and Venezuela. The number of members of the societies and groups associated with LAFeBS is now around 2,000, and they work mainly in academia, industry, and government agencies throughout Latin America and the Iberian Peninsula. The Federation holds a meeting every 3 years, bringing together over 500 researchers in the multidisciplinary fields representing biophysics. The Federation provides the Latin American Postgraduate Program of Biophysics (POSLATAM) together with International Union for Pure and Applied Biophysics (IUPAB). POSLATAM, currently coordinated by Dr Marcelo Morales (Brazil), is the first regional initiative at postgraduate level in Latin America and already has 257 students (masters and PhD students from more than 30 postgraduate programs associated with POSLATAM from Argentina, Brazil, Colombia, Uruguay and Venezuela). POSLATAM also sponsors thematic and annual courses, workshops, and conferences in Latin America.Fil: Morales, Marcelo M. Universidade Federal do Rio de Janeiro; BrasilFil: Alonso, Silvia del Valle.

Arqueología ambiental del holoceno temprano y medio en la Puna Seca Argentina
No full textEsta tesis se dedica a generar un modelo palcoambiental multi-
escalas a partir del cual se derivan hipótesis o expectativas arqueológicas sobre las características
de las ocupaciones humanas durante la primera mitad del Holoceno en la Puna Seca Argentina.
Con este fin, buena parte de este volumen se ha dedicado a la obtención de marcos de referencia
ambientales y datos paleoambientalcs que constituyen la materia prima
fundamental para la construcción del mencionado modelo paleoambiental de la Puna Seca

abordan diferentes aspectos de los patrones organizativos los grupos Cazadores-Recolectores. Estas expectativas se han derivado de supuestos
y modelos teóricos pertenecientes a la arqueología ambiental, la ecología evolutiva y otros
enfoques con una perspectiva ecológica. Finalmente, se discute el potencial predictivo de parte de
estas expectativas con la evidencia arqueológica disponible hasta el momento para este período

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
