pensamiento privilegiadas en las demandas académicas del profesorado en Ciencias de la
Educación, para examinarlas en la relación que mantienen con las capacidades de los
estudiantes cuando intentan darles adecuada respuesta. Específicamente, a partir del análisis de
tareas académicas demandadas en el último año universitario, se relaciona y discute las
consignas de escritura, su resolución y corrección para interpretarlas en clave de niveles de
procesamiento cognitivo de la información. El estudio se realiza en la Facultad de Humanidades
de la Universidad Nacional del Nordeste. Se tomaron muestras de asignaturas y de estudiantes.
Las consignas de los exámenes contienen indicaciones de variada complejidad que orientan los
procesos cognitivos. Estas órdenes promueven, potencialmente, procesos mentales de variada
complejidad e integran distintos niveles cognitivos de procesamiento de la información.
Asimismo, estos niveles plantean modalidades de relación con el conocimiento, mientras que
las tareas que exigen menor esfuerzo cognitivo se asocian a la adquisición e integración del
conocimiento, aquellas que requieren mayor esfuerzo buscan profundizar y re-significar el
conocimiento. Las dificultades en la elaboración de las respuestas refieren, en su mayoría, a las
producciones que requieren operaciones cognitivas orientadas a re-significar y profundizar el

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
Manejo de trips “Caliothrips phaseoli” en el cultivo de soja
Full text linkLa siembra directa, en virtud de sus notables ventajas frente a otras formas de cultivo, favoreció la aparición y difusión de otras plagas, asociadas a suelos no-roturados (Aragón, 1997). El mismo autor observó un aumento de las infestaciones de trips destacándose los daños en plántulas de alfalfa durante el otoño y en soja durante los meses de verano (Aragón, 2002). Los trips se encuentran entre los artrópodos cuyas poblaciones son más abundantes en el cultivo de soja (Irwin et al., 1979), especialmente en Brasil y Argentina (Gamundi et al., 2005; Janini et al., 2011; Perotti y Gamundi, 2009; Perotti et al., 2011).EEA Marcos JuárezFil: Flores, Fernando Miguel.

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
Introducing the Inner Structure of the Magnetic Atom in the Interaction Between a Transition Metal Atom Impurity and a Metal Surface
No full textThis paper presents a review of the work performed by the authors toincorporate the inner structure of a d-shell magnetic atom in the description of the many-body interaction between a transition metal atom impurity and a metal host.Two main assumptions are made in this approach: (i) the magnetic atom has anorbital singlet with a total electronic spin S (as corresponds to a case for whichthe angular moment is quenched); (ii) the first Hunds rule determines the innerelectronic structure of the magnetic atom. Using these two assumptions and therotational symmetry of the electronic spin, an ionic Hamiltonian is introduced and, in a further step, the effective exchange metal atom coupling and the impurity Kondo temperature are analyzed.Fil: Flores, Fernando.

A rotation‐free shell triangle for the analysis of kinked and branching shells
Full text linkThis paper extends the capabilities of previous BST and EBST rotation-free thin shell elements to the analysis of kinked and branching surfaces. The computation of the curvature tensor is first redefined in terms of the angle change between the normals at the adjacent elements. This allows to deal with arbitrary large angles between adjacent elements and to treat kinked surfaces. A relative stiffness between elements is introduced to consider non-homogeneous surfaces. This idea is latter generalized to deal with branching shells. Several linear and non-linear examples are presented showing that the formulation leads to the correct results.Fil: Flores, Fernando Gabriel.

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
