The Mutual Shaping of Technology and Society in Videotex Newspapers: Beyond the Diffusion and Social Shaping Perspectives     

Pablo J. Boczkowski 《The Information Society》2004,20(4):255-267

This article argues that a mutual shaping lens enables a more encompassing account of the joint processes of technological and social change in new media than the diffusion of innovations and social shaping of technology perspectives. Drawing from recent work in sociology and history of technology, organization studies, social informatics, and computer-supported cooperative work, this article suggests that the shaping and diffusion of media artifacts are so intimately tied that they should be seen as the two sides of the same innovation coin. Using examples from the history of videotex newspapers in the United States, the analysis shows that actors simultaneously pursued interdependent technological and social transformations, that this was an ongoing process in which partial outcomes in the technological domain influenced social events at a later phase—and vice versa—and that such process was influenced by historical developments.  相似文献   

The sign of the new millennium. Organisational changes and job satisfaction at Spanish public universities     

Jon Olaskoaga‐Larrauri  Xabier Gonzlez‐Laskibar  Miren Barrenetxea‐Ayesta  Pablo Díaz‐De‐Basurto‐Uraga 《European Journal of Education》2019,54(1):137-150

This article describes the ramifications that recent organisational changes in the Spanish higher education sector have had on levels of job satisfaction among teaching staff. The research gathered their opinions on recent changes affecting their teaching duties, using job satisfaction scales in different areas of their academic work. The results point to a large number who claim to have seen their job satisfaction diminish over the period in which the organisational changes have taken hold. This sense of loss of job satisfaction is positively and significantly related to growing standardisation and to the erosion of the principles of collegiality, but negatively to the initiatives for improving the coordination between teaching staff and the assessment of the quality of their work.  相似文献

Education and social change in Spain: from crisis to opportunity     

Pablo Cortés-González  J.Ignacio Rivas-Flores  Analía E. Leite-Méndez 《Ethnography and Education》2016,11(2):204-221

This paper analyses a particular socio-educational experience in a marginalised neighbourhood in Malaga, Spain. This initiative came about as an institutional proposal to combat neoliberal austerity policies and is known as the ‘Casa de la Buena Vida'. It aims to generate new educational practices based on solidarity, dignity and justice. The methodology followed entailed carrying out an ethnography at this institution, participating in the initiative over a period of 4 years. At the same time, life histories of some of its most notable members were drawn up. In the results section we offer an analysis of the particular identities that are created as a consequence of the living conditions, social conflicts, multicultural nature and survival strategies that operate in a welfarist policy system. We also analyse this institution's socio-educational proposal using alternative social practices that enable other subjectivities to develop.  相似文献   

Avoiding communication barriers in the classroom: the APEINTA project     

Ana Iglesias  Javier Jiménez  Pablo Revuelta  Lourdes Moreno 《Interactive Learning Environments》2016,24(4):829-843

Education is a fundamental human right, however unfortunately not everybody has the same learning opportunities. For instance, if a student has hearing impairments, s/he could face communications barriers in the classroom, which could affect his/her learning process. APEINTA is a Spanish educational project that aims for inclusive education for all. This project proposes two main accessible initiatives: (1) real-time captioning and text-to-speech (TTS) services in the classroom and (2) accessible Web-learning platform out of the classroom with accessible digital resources. This paper presents the inclusive initiatives of APEINTA. Also an evaluation of the into-the-classroom initiative (real-time captioning and TTS services) is presented. This evaluation has been conducted during a regular undergraduate course at a university and during a seminar at an integration school for deaf children. Forty-five hearing students, 1 foreign student, 3 experts in captioning, usability and accessibility, and 20 students with hearing impairments evaluated these services in the classroom. Evaluation results show that these initiatives are adequate to be used in the classroom and that students are satisfied with them.  相似文献   

Bridging memory-based collaborative filtering and text retrieval     

Alejandro Bellogín  Jun Wang  Pablo Castells 《Information Retrieval》2013,16(6):697-724

When speaking of information retrieval, we often mean text retrieval. But there exist many other forms of information retrieval applications. A typical example is collaborative filtering that suggests interesting items to a user by taking into account other users’ preferences or tastes. Due to the uniqueness of the problem, it has been modeled and studied differently in the past, mainly drawing from the preference prediction and machine learning view point. A few attempts have yet been made to bring back collaborative filtering to information (text) retrieval modeling and subsequently new interesting collaborative filtering techniques have been thus derived. In this paper, we show that from the algorithmic view point, there is an even closer relationship between collaborative filtering and text retrieval. Specifically, major collaborative filtering algorithms, such as the memory-based, essentially calculate the dot product between the user vector (as the query vector in text retrieval) and the item rating vector (as the document vector in text retrieval). Thus, if we properly structure user preference data and employ the target user’s ratings as query input, major text retrieval algorithms and systems can be directly used without any modification. In this regard, we propose a unified formulation under a common notational framework for memory-based collaborative filtering, and a technique to use any text retrieval weighting function with collaborative filtering preference data. Besides confirming the rationale of the framework, our preliminary experimental results have also demonstrated the effectiveness of the approach in using text retrieval models and systems to perform item ranking tasks in collaborative filtering.  相似文献   

An annual JCR impact factor calculation based on Bayesian credibility formulas     

Patricia Pérez-Hornero  José Pablo Arias-Nicolás  Antonio A. Pulgarín  Antonio Pulgarín 《Journal of Informetrics》2013,7(1):1-9

Our aim deals with appraising the annual impact calculation of journals belonging to the JCR, in terms of the expected citation (with or without selfcitations) by published paper in a range of k-years. A Bayesian approach to the problem, should reflect not only the current prestige of a journal, but also taking into account its recent trajectory. In this wide context, credibility theory becomes an adequate mechanism deciding whether journal's impact factor calculation to be more or less plausible. Under prior belief that journal quality is determined by its impact factor, we model the citation-quality process by choosing a conjugated family of the exponential class in order to obtain a net impact credibility formula. Proposed weighting schema produces the effect of smoothing out any sudden increases or decreases in the year-by-year impact factor.  相似文献   

El currículum invisible: Los medios de comunicación y la prensa en la escuela     

Pablo del Río 《Cultura y Educación》2013,25(3-4):153-165

¿Cuál es la alternativa cuando uno se plantea el problema de que el niño aprende cosas triviales que le interesan y no aprende cosas importantes que no le interesan? ¿Son tan triviales las triviales? ¿Son tan importantes las que no le interesan?

Parece que la incorporación de los medios a la escuela está ayudando a establecer ese necesario puente entre el curriculum formal y el informal, entre la escuela y el mundo real. El caso de la prensa, alentado por su obvia relación con el proceso de lectoescritura, ha llevado también a extender el experimento al impulso que el uso de los medios en clase puede dar al aprendizaje de los diversos códigos y lenguajes.

Este artículo revisa en la primera parte algunos conceptos básicos para entender el papel de los medios en la educación, sobre todo en relación con el sentido de ésta para el alumno y ofrece en la segunda parte una serie de propuestas concretas para su integración en el curriculum de la reforma y para la aplicación práctica.  相似文献   

«¡Pásame la brújula!» Un ejemplo de metodología histórico-cultural en la enseñanza de las matemáticas     

Pablo del Río 《Cultura y Educación》2013,25(11-12):27-54

La enseñanza de las matemáticas ha estado tradicionalmente condicionada por una visión universalista de las capacidades mentales, que ha tenido poco en cuenta que el lenguaje matemático no es una abstracción aprioristica y acontextual, sino que pasa por la utilización de «metáforas» instrumentales utilizadas por los propios matemáticos a lo largo de la historia y escamoteada al niño en la escuela. En este artículo se expone un diseño didáctico en que se hace una apuesta fuerte por una enseñanza de la geometría que recoja los instrumentos culturales (las «metáforas» materiales) presentes en nuestro entorno y los utilice en sus diseños como mediadores entre la realidad y los conceptos.  相似文献   

Ground Reaction Force Differences in the Countermovement Jump in Girls With Different Levels of Performance     

Pablo Floría  Andrew J. Harrison 《Research quarterly for exercise and sport》2013,84(3):329-335

Purpose: The aim of this study was to ascertain the biomechanical differences between better and poorer performers of the vertical jump in a homogeneous group of children. Method: Twenty-four girls were divided into low-scoring (LOW; M _age = 6.3 ± 0.8 years) and high-scoring (HIGH; M _age = 6.6 ± 0.8 years) groups based on their performance on the vertical jump. The force-, velocity-, displacement-, and rate of force development (RFD)-time curves of vertical jumps were analyzed to determine the differences between groups. Results: The analysis of the data showed differences in the pattern of the ensemble mean curves of the HIGH and LOW groups, although the majority of the differences occurred during the eccentric contraction phase of the jump. The differences in the HIGH group with respect to the LOW group were: lower force at the beginning of the movement, higher speed and RFD during the eccentric phase, high force at the beginning of the concentric phase, higher velocity during the concentric phase, and a higher position at takeoff. Conclusion: The results showed that the HIGH group achieved a higher jump height than did the LOW group by increasing the effectiveness of the countermovement and achieving a more advantageous position at takeoff.  相似文献
