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
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

Estudio de las motivaciones internas y externas para la elección de modalidad del alumnado de Bachillerato. Incidencia en la didáctica de las Ciencias Sociales
Full text linkLa etapa de Bachillerato es fundamental para los estudiantes de Educación Secundaria, ya que en ella se toman decisiones que van a determinar su futuro académico y profesional. En esta etapa, el alumnado debe decantarse por una modalidad de estudios (Ciencias, Humanidades y Ciencias Sociales o Arte). El análisis de datos de matriculación de estudiantes en las diversas modalidades de estudios llama la atención por el hecho de que más de la mitad del alumnado de la etapa se decanta por estudiar la modalidad de Ciencias, mientras que el resto se reparte entre las otras modalidades posibles.
La presente Tesis Doctoral es un análisis de las motivaciones de tipo interno y externo de los estudiantes de Bachillerato en su elección de modalidad de estudios, que tiene como finalidad conocer los factores que motivan a los estudiantes a decantarse por una modalidad.
Para este estudio se ha empleado una metodología híbrida, utilizando un cuestionario de 21 ítems de motivaciones internas y externas, para el análisis cuantitativo; y el análisis de redacciones sobre los motivos por los que los estudiantes escogen modalidad, analizados con el software WebQDA.
Los resultados señalan una mayor incidencia de los factores de motivación externa en los estudiantes de esta etapa, por encima de los factores de motivación interna.
Desde ese análisis, se ha diseñado una intervención de aula, que tiene como objeto poner de relieve la relación estudio-configuración de la sociedad, y generar reflexión acerca de las motivaciones desde las que se eligen los estudios universitarios.The Baccalaureate stage is essential for Secondary Education students, since it makes decisions that will determine their academic and professional future. At this stage, students must opt for a modality of studies (Science, Humanities and Social Sciences or Art). The analysis of student enrolment data in the various modalities of studies draws attention because more than half of the students in the stage choose to study the modality of Science, while the rest is divided between the other modalities possible.
This Doctoral Thesis is an analysis of the internal and external motivations of high school students in their choice of study modality, which aims to know the factors that motivate students to opt for a modality.
For this study a hybrid methodology has been used, using a questionnaire of 21 items of internal and external motivations, for the quantitative analysis; and the analysis of newsrooms on the reasons why students choose modality, analyzed with WebQDA software.
The results indicate a greater incidence of external motivation factors in the students of this stage, above the internal motivation factors.
From that analysis, a classroom intervention has been designed, which aims to highlight the study-configuration relation society andety, and generate reflection on the motivations from which university studies are chosen
Experience of digital competences and use of heritage in the Social Sciences didactics
Full text linkUna de las tendencias más seguidas en la Didáctica de las Ciencias Sociales en la actualidad es la incorporación progresiva de tecnologías y recursos digitales al proceso de enseñanza-aprendizaje. El uso de estos recursos tiene una alta carga motivacional en el alumnado y contribuye a completar las aportaciones de otros recursos utilizados de manera tradicional en esta área de conocimiento, como es el uso del patrimonio histórico y cultural. Este trabajo es una combinación de ambos tipos de recursos, aplicado al aprendizaje de los contenidos relacionados con el sistema feudal, en la asignatura de Historia en 2º de ESO.One of the most followed trends in the Social Sciences Didactics at present is the progressive incorporation of digital technologies and resources to the teaching-learning process. The use of these resources has a high motivational load on the students and contributes to completing the contributions of other resources used in a traditional way in this area of knowledge, such as the use of historical and cultural heritage. This experience is a combination of both types of resources, applied to the learning of the contents related to the feudal system, in the subject of History in 2nd of ESO
Íber : didáctica de las ciencias sociales, geografía e historia
No full textResumen basado en el de la publicaciónSe describe cómo la motivación del alumnado es uno de los retos con los que se encuentra todo docente, de cualquier materia y en cualquier etapa de la educación. Una de las claves para conseguir esta motivación es la introducción de metodologías activas. La modalidad de aprendizaje flipped classroom, junto con la técnica Just in time teaching (JITT), permite romper la sensación de que se enfrentan solos al aprendizaje teórico de los contenidos.Biblioteca del Ministerio de Educación y Formación Profesional; Calle San Agustín, 5; 28014 Madrid; Tel. +34917748000; [email protected]
