RESUMEN

En la Argentina de mediados del siglo XX comenzó con un fuerte sesgo estatal a pensarse en la cinematografía escolar como un eficaz método pedagógico de difusión de un pretendido ideario simultáneamente emancipador y propagandístico. Del mismo modo que otros gobiernos de diversas filiaciones ideológicas, la presidencia de Juan Domingo Perón estuvo signadas por una política de la imagen que se enfocó en educar los sentidos de las futuras generaciones de argentinos. En este caso se muestra una política en particular, como lo fue la revista Noticioso entre 1952 y 1955, cuyo análisis refleja el exponencial crecimiento del rol estatal, hasta ocupar un lugar central no sólo en la reproducción de cine educativo, sino también de la filmación, distribución y proyección de los celuloides. En síntesis, con la creación en 1948 del Departamento de Radioenseñanza y Cinematografía Escolar como organismo específicamente dedicado a la enseñanza audiovisual, y especialmente con la publicación de Noticioso, puede verse un síntoma de las políticas gubernamentales que el peronismo forjó para la formación de nuevos ciudadanos, en el marco de la pretendida Nueva Argentina.  相似文献   

Injury prevention in male youth soccer: Current practices and perceptions of practitioners working at elite English academies     

Paul J. Read  Pablo Jimenez  Jon L. Oliver  Rhodri S. Lloyd 《Journal of sports sciences》2018,36(12):1423-1431

Forty-one practitioners inclusive of physiotherapists, sports scientists and strength and conditioning coaches from the academies of elite soccer clubs in the United Kingdom completed an on-line questionnaire which examined their: (1) background information; (2) perceptions of injury occurrence and risk factors; (3) screening and return to play; and (4) approach to designing and delivering injury prevention programmes with a response rate of 55% (41/75). Contact injuries were the most common mechanism reported and players between 13–16 years of age were perceived to be at the greatest risk. Pertinent risk factors included: reduced lower limb and eccentric hamstring strength, proprioception, muscle imbalances, and under developed foundational movement skills. Joint range of motion, jump tests, the functional movement screen, overhead and single leg squats were the most utilised screening methods. Training modalities rated in order of importance included: resistance training, flexibility development, agility, plyometrics and balance training. Training frequency was most commonly once or twice per week, during warm-ups, independent sessions or a combination of both. Injury prevention strategies in this cohort appear to be logical; however, the classification of injury occurrence and application of screening tools to identify “at risk” players do not align with existing research. The frequency and type of training used may also be insufficient to elicit an appropriate stimulus to address pertinent risk factors based on current recommendations.  相似文献   

The effects of service convenience and perceived quality on perceived value,satisfaction and loyalty in low-cost fitness centers     

Jerónimo García-Fernández  Pablo Gálvez-Ruíz  Jesús Fernández-Gavira  Luisa Vélez-Colón  Brenda Pitts  Ainara Bernal-García 《Sport Management Review》2018,21(3):250-262

Due to its importance in fitness centers, a number of authors have explored and analyzed loyalty. However, two characteristics not yet examined are service convenience in fitness center chains and low-cost fitness centers (an emerging business model). In the present study, the authors sought to understand the relationship among perceived quality and service convenience on perceived value, satisfaction, and client loyalty in low-cost fitness centers. Clients (N = 763; 381 women and 382 men) from three low-cost Spanish fitness centers were surveyed, revealing a positive relationship among the variables studied. Findings demonstrate the importance of proper management of non-monetary sacrifices and perceived quality by the managers of these sport organizations, since client loyalty could depend on factors of these emerging sport models.  相似文献   

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

Pablo J. Boczkowski 《The Information Society》2013,29(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

Statistical biases in Information Retrieval metrics for recommender systems     

Alejandro?BellogínEmail authorView author&#;s OrcID profile  Pablo?Castells  Iván?Cantador 《Information Retrieval》2017,20(6):606-634

There is an increasing consensus in the Recommender Systems community that the dominant error-based evaluation metrics are insufficient, and mostly inadequate, to properly assess the practical effectiveness of recommendations. Seeking to evaluate recommendation rankings—which largely determine the effective accuracy in matching user needs—rather than predicted rating values, Information Retrieval metrics have started to be applied for the evaluation of recommender systems. In this paper we analyse the main issues and potential divergences in the application of Information Retrieval methodologies to recommender system evaluation, and provide a systematic characterisation of experimental design alternatives for this adaptation. We lay out an experimental configuration framework upon which we identify and analyse specific statistical biases arising in the adaptation of Information Retrieval metrics to recommendation tasks, namely sparsity and popularity biases. These biases considerably distort the empirical measurements, hindering the interpretation and comparison of results across experiments. We develop a formal characterisation and analysis of the biases upon which we analyse their causes and main factors, as well as their impact on evaluation metrics under different experimental configurations, illustrating the theoretical findings with empirical evidence. We propose two experimental design approaches that effectively neutralise such biases to a large extent. We report experiments validating our proposed experimental variants, and comparing them to alternative approaches and metrics that have been defined in the literature with similar or related purposes.  相似文献   

How do firms’ knowledge bases affect intra-industry heterogeneity? : An analysis of the Spanish pharmaceutical industry     

Pablo D’Este 《Research Policy》2005,34(1):33-45

This paper aims to contribute to the analysis of within industry inter-firm variety. The paper develops two themes: (i) the analysis of intra-industry heterogeneity, and (ii) the extent to which higher performance is associated with the capacity of firms to expand their knowledge base. The main contribution of the paper is empirical, based on a data source consisting of information on documents published in international scientific journals by Spanish pharmaceutical firms. The empirical results support the argument that the firm's knowledge base is a main driver of persistent heterogeneity within industries. We find systematic variety in terms of how firms articulate their research activities, and positive correlation between firms’ knowledge diversification and performance.  相似文献   

Circadian Rhythms in Cognitive Processes: Implications for School Learning     

Pablo Valdez  Candelaria Ramírez  Aída García 《Mind, Brain, and Education》2014,8(4):161-168

Circadian variations have been found in cognitive processes, such as attention, working memory, and executive functions, which may explain oscillations in the performance of many tasks. These cognitive processes improve during the day and decrease during the night and early hours of the morning. Sleep deprivation further decreases these cognitive processes during daytime hours. This review analyses the recent findings on circadian rhythms in cognitive processes, as well as the implications of these rhythms for school learning.  相似文献
