Las ciencias cognitivas en el contexto ense?anza-aprendizaje del análisis de contenido
Extremeo,Ana;
Informaci?3n, cultura y sociedad , 2002,
Abstract: the role that cognitive sciences are performing within the knowledge world is analyzed in a general way, and, the content document analysis (cda) is particularly analyzed. it begins with a reflection about the implications that either the informative message transmitter or recipient has to understand the real essence of the message. those aspects should have to be taken into account by the teacher in order to transmit the students a rigorous and efficient methodology for the development of the cda. in that sense, a concrete methodology, the conceptual maps whose technique raises the representation of concepts or knowledgement of a specific area are analyzed, as well as the relations among them.
Las ciencias cognitivas en el contexto ense anza-aprendizaje del análisis de contenido Cognitive Sciences in the Teaching-Learning Context of the Content Analysis
Ana Extremeo
Información, Cultura y Sociedad , 2002,
Abstract: Se analiza el papel que las ciencias cognitivas vienen desempe ando en el universo del conocimiento, en general, y en el análisis documental de contenido (ADC), en particular. Se parte de una reflexión acerca de las implicaciones que tienen tanto el emisor como el receptor del mensaje informativo para comprender la verdadera esencia del mensaje. Estos aspectos han de ser tenidos en cuenta por el docente para transmitir a sus alumnos una metodología rigurosa y eficaz para el desarrollo del ADC. En este sentido, se analiza una metodología concreta, los mapas conceptuales, cuya técnica aborda la representación de conceptos o conocimientos de un área determinada, así como las relaciones entre ellos.

Calidad de la indización e incidencia de errores en la base de datos ECOSOC
Extremeo, Ana
Revista Espa?ola de Documentación Científica , 1999,
Abstract: Results of the analysis and evaluation of ECOSOC database are presented. Quality indicators are used in order to evaluate the indexing process. Formal indicators are used in the analysis of the records structure and in the process of error detection. Se presentan los resultados del análisis y de la evaluación de la base de datos ECOSOC, producida y distribuida por el CINDOC, relativos a los registros sobre Ciencia Política. Se aplican indicadores de calidad para la evaluación del proceso de indización de los términos empleados en la descripción temática de la base de datos, así como indicadores formales con el fin de analizar la estructura de los registros bibliográficos e identificar el índice de errores contenidos en cada uno de los campos que componen dichos registros.

Criterios para la selección de bases de datos en línea, en el área de Economía y Administración de empresas, orientados a la creación de consorcios regionales en bibliotecas universitarias
Sabelli, Martha,Extremeo, Ana
Revista Espa?ola de Documentación Científica , 2003,
Abstract: This article provides different elements to establish evaluation criteria, that serve as aid in the acquisition of on-line data bases. The purpose is to agglutinate the most representative ones in a specified sector in order to facilitate the establishment of librarian partnerships that make possible the access to the information within the geographical area of MERCOSUR. En este trabajo se analizan diferentes elementos, necesarios para establecer criterios de evaluación, que sirvan de ayuda en la adquisición de bases de datos en línea con la finalidad de aglutinar las más representativas en un sector determinado y, de esta manera, facilitar el establecimiento de consorcios bibliotecarios que posibiliten el acceso a la información dentro del área geográfica de MERCOSUR.
Bibliotecarios universitarios – Profesores. Caminos convergentes?
Amante, María Jo?o,Extremeo, Ana
Revista Espa?ola de Documentación Científica , 2012,
Abstract: The changes in higher education brought about by the Bologna process not only affect teaching, but also units within the institution that play a critical role in assuring compliance of the teaching-learning process with the requirements. Among them is the university library, whose officers occupy a key position that requires them to rethink their professional responsibilities and to adopt a methodology for facilitating the acquisition of the competencies and skills demanded by today’s society. A first step for defining the new role of university librarians consists of analyzing the faculty’s perceptions of them, in order to plan for the necessary collaboration between the two collectives. Los cambios que el proceso de Bolonia ha impuesto en la educación universitaria no sólo ata en a la docencia sino también a organismos incluidos dentro de la propia institución cuya aportación en el proceso ense anza-aprendizaje es vital para cumplir los requisitos exigidos. Entre ellos, la biblioteca universitaria y sus responsables ocupan un lugar central que los obliga a replantearse sus cometidos profesionales y a adoptar una metodología de trabajo que ayude a la adquisición de las competencias y habilidades que actualmente la sociedad demanda. Un primer paso para delimitar el nuevo rol del bibliotecario universitario consiste en analizar las percepciones que los docentes tienen sobre ellos y, de esta manera, planificar la necesaria e imprescindible colaboración entre ambos colectivos.
Stress Loops Effect in Ductile Failure of Mild Steel  [PDF]
O.O. Oluwole
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.84026
Abstract: A simulation study of effect of stress on mild steel microstructure has revealed stress loops at areas of stress application which are believed to be the root cause of the ductile failure morphology (cup and cone) in ductile alloys under plane strain conditions. The areas of concentration of these stress loops were observed to be that of subsequent instability (or necking) observed in mild steel and other materials of low friction (flow) stress. Shear stress loops with angular bearing of 450 to the tensile axis were observed to instigate both the failure site and shear morphology in these materials. In plane stress conditions, shear was seen to be that of a wave shape running obliquely to area of stress application resulting in oblique necking observed in thin mild steel sheets.
Boundary Value Problem for an Operator-Differential Riccati Equation in the Hilbert Space on the Interval  [PDF]
O. O. Pokutnyi
Advances in Pure Mathematics (APM) , 2015, DOI: 10.4236/apm.2015.514081
Abstract: The paper is devoted to obtaining the necessary and sufficient conditions of the solvability of weakly perturbed boundary-value problems for the nonlinear operator-differential Riccati equation in the Hilbert space on the interval and whole line with parameter ?. We find the solution of the given boundary value problem which for ε = 0 turns in one of the solutions of generating boundary value problem. Solution of the generating problem is constructed with the using generalized operator in analytical form. Iterative process for finding of solutions of weakly nonlinear equation with quadratic error is constructed.
Vertex-transitive maps on a torus
O. Such
ACTA MATHEMATICA UNIVERSITATIS COMENIANAE , 2011,
Abstract: We examine FVT (free, vertex transitive) actions of wallpaper groups on semiregular tilings. By taking quotients by lattices we then obtain various families of FVT maps on a torus, and describe the presentations of groups acting on the torus. Altogether there are 29 families, 5 arising from the orientation preserving wallpaper groups and 2 from each of the remaining wallpaper groups. We prove that all vertex-transitive maps on torus admit an FVT map structure.
