Medición y realidad: reflexiones para una economía realista
No full textThe work constitutes a general exposition of the economic circulation analysis elaborated by B. Lonergan. Departing from different philosophical assumptions than those implicit in dominant economic theory, this author developed a systemic approach to the economic problem, which reveals certain insufficiencies in current economic measurement. As a matter of fact, when fundamental categories of analysis change, so do the variables of interest. In the first section, the gnoseological and epistemological assumptions developed by this author are exposed. These foundations allow us to recognize with better clarity the weak basis of current approaches. After a brief enumeration of some of the critiques posed to the current paradigm by diverse authors, the general lines of the scheme proposed by Lonergan are exposed.El trabajo constituye una presentación general del análisis de la circulación económica elaborado por B.

En la primera sección se exponen los supuestos gnoseológicos y epistemológicos realistas desarrollados por este autor.

Una lectura crítica de “El Capital del siglo XXI” desde la noción de innovación
No full textResumen: el artículo realiza una revisión de la obra “El Capital del siglo XXI”, de T. Piketty, partiendo de la noción de innovación como fuente del aumento de productividad (y, por ende, del rendimiento del capital) y un enfoque sistémico o de circulación de la economía. A la par que se ponderan los méritos de la obra, particularmente en lo que hace al enfoque de largo plazo, a la vuelta a las grandes preguntas de la economía clásica, al ejercicio de diálogo con otras disciplinas o a la recopilación de estadísticas, se señalan algunas incongruencias teóricas que ponen en cuestión algunas de las conclusiones extraídas por el autor.Abstract: The paper offers a revision of the work “Capital in the XXI century”, by T. Piketty, taking the notion of innovation as the source of productivity growth (and hence, of capital returns) as a criterion as well as a systemic or circulation analysis approach to the economy. The merits of the work –its long-term scope, the return to the big questions posed by classical economy, the exercise of dialogue with other disciplines, or the collection of statistics– are highlighted. On the other side, however, some theoretical inconsistencies which put into question some conclusions drawn by the author are also remarked
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
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
Aproximaciones al desarrollo : primera parte
Get PDFEsta extensa cita del teólogo B. Lonergan liga de manera formidable las perspectivas científica y moral en relación con el desarrollo. Se explica allí que el estancamiento y polarización de las sociedades se debe a las estructuras sociales, a las ideologías que las justifican y, en última instancia, al egoísmo que se encubre en ideologías para justificar dichas estructuras - las que, a su vez, lo han conformado-. La estructura alienante termina obturando el progreso y la autotrascendencia de personas y sociedades por fallos en la atención a los datos de la realidad, a su interpretación, a la razonabilidad de ésta y/o a la responsabilidad que decide qué interpretación y qué caminos a seguir son los correctos (Lonergan, [1973] 1994: 59-60). Es necesaria, por tanto, una perspectiva teórica abierta para no ser presa fácil de los propios intereses de los investigadores. Teniendo como trasfondo esta perspectiva básica pretendo fundar las reflexiones que siguen en torno al desarrollo..
