Jewish Education,Past and Present: Israel Friedlaender Re-Visited     

Gil Graff 《Journal of Jewish Education》2016,82(4):311-328

A century ago, Israel Friedlaender—scholar, communal activist, and educator—played a key role in such educational institutions as the Teachers Institute of JTS, the Bureau of Jewish Education, the Menorah Society, Young Israel, and Young Judea. A JTS professor and prolific writer, Friedlaender has been described as “the teacher of the Jewish youth of that generation.” Yet, scant attention has been devoted to exploring his educational thought and action agenda. This retrospective focuses on Friedlaender’s activities and impact in advancing Jewish education and considers the relationship of his legacy to current directions in the field.  相似文献   

Prediction of performance by heart rate-derived parameters in recreational runners

We investigated whether heart rate (HR)-derived parameters are accurate performance predictors in endurance recreational runners. One hundred thirty recreational athletes completed an incremental running test (4´running + 1´rest). After each stage, we recorded HR, % of maximum HR (%HRmax), and blood lactate. We also assessed HR after each recovery period, and calculated lactate and HR recovery thresholds and HR deflection point. We tested these parameters for associations with running performance, as measured by peak treadmill speed (PTS) and personal best International Association of Athletics Federations (IAAF) score. The %HRmax at 14.5 km·h^?1 correlated with PTS (r = ?0.92), and IAAF score (rho = ?0.80). The magnitudes of the correlations of lactate-related parameters with PTS (|r| = 0.84 to 0.86) or IAAF score (|rho| = 0.70 to 0.77) in absolute values were slightly lower. The correlations detected between other HR-derived parameters and running performance were weaker (|r or rho| = 0.24 to 0.70). Regression models identified %HRmax at 14.5 km·h^?1 as the strongest predictor of both PTS (β = ?0.72) and IAAF score (β = ?0.72). Consequently, tests based on %HRmax may provide a non-invasive and inexpensive alternate method for predicting the performance of these athletes.  相似文献   

Tensiomyography parameters and jumping and sprinting performance in Brazilian elite soccer players     

Saulo Gil  Irineu Loturco  Valmor Tricoli  Carlos Ugrinowitsch  Ronaldo Kobal  Cesar Cavinato Cal Abad 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(3):340-350

Tensiomyography has been suggested as an indirect marker of muscle stiffness, which is associated with strength/power performance. Therefore, it is reasonable to suggest that tensiomyography parameters could be associated with power-related motor tasks. The purpose of this study was to investigate the association between tensiomyography parameters (from rectus and biceps femoris) and jumping and sprinting abilities in elite soccer players. In addition, we used tensiomyography parameters to compare the lateral symmetry between dominant and non-dominant legs. Twenty elite soccer players (age: 23.3 ± 4.8 years; height: 183.5 ± 6.6 cm; weight: 77.8 ± 7.5 kg) volunteered to participate in the study. Significant moderate negative correlations between biceps femoris displacement and contact time (r = –0.5, p = 0.03), rectus femoris displacement and contact time (r = –0.51, p = 0.02), and a significant moderate correlation between biceps femoris displacement and reactive strength index (r = 0.5, p = 0.03) were found. There were no correlations between tensiomyography parameters and power-related motor tasks. In addition, no differences in tensiomyography parameters between dominant and non-dominant legs were found. Our data suggest that tensiomyography parameters are not associated with power-related motor tasks performance in elite soccer players.  相似文献   

The role of habituation of the response to LiCl in the US-preexposure effect     

de Brugada I  González F  Gil M  Hall G 《Learning & behavior》2005,33(3):363-370

In two experiments, rats received preexposure consisting of six intraperitoneal injections of lithium chloride (LiCl). This treatment reduced the magnitude of the unconditioned response (UR; suppressed consumption of a novel flavor) evoked by an additional injection (Experiment 1) or by oral consumption (Experiment 2) of LiCl. In both experiments, preexposure also attenuated the acquisition of a conditioned aversion with an LiCl injection as the unconditioned stimulus (US) but had no effect on the aversion produced when the US was oral consumption of LiCl (Experiment 2). These results are consistent with the view that the reduced ability of the preexposed US to serve as a reinforcer depends on blocking by injection-related cues and is independent of habituation of the UR recorded in the present study. Possible interpretations of this dissociation are discussed.  相似文献   

A Comparative Citation Analysis of Web of Science,Scopus, and Google Scholar     

Michael Levine-Clark  Esther L. Gil 《Journal of Business & Finance Librarianship》2013,18(1):32-46

This article presents the results of a comparative study of Web of Science (WoS), Scopus, and Google Scholar (GS) for a set of 15 business and economics journals. Citations from the three sources were analyzed to determine whether one source is better than another, or whether a new database such as Scopus, or a free database such as GS could replace WoS. The authors concluded that scholars might want to use alternative tools collectively to get a more complete picture of the scholarly impact of an article.  相似文献   

Psicología Educativa y Didáctica de las ciencias: los procesos de enseñanza/aprendizaje de las ciencias como lugar de encuentro     

Daniel Gil 《Infancia y Aprendizaje》2013,36(62-63):171-186

Resumen

Se cuestiona el rechazo aprioristico de buena parte del profesorado de ciencias (incluido el implicado en innovaciones e investigaciones didácticas) hacia las «ciencias de la educación» en general, cuyas contribuciones son consideradas, sin apenas matizaciones, «abstractas», «puramente librescas» y «producidas sin contacto con la realidad de las aulas».

Se cuestiona igualmente la consideración de la didáctica de las ciencias como campo de «aplicación» y se fundamenta la necesidad de reconocerla como un dominio específico de conocimientos que no queda subsumido en el de la psicología educativa ni se reduce a una dimensión práctica.

Se avanzan, por último, algunas propuestas de cooperación.  相似文献   

Internal,External, and Government Political Efficacy: Effects on News Use,Discussion, and Political Participation     

Homero Gil de Zúñiga  Trevor Diehl  Alberto Ardévol-Abreu 《广播与电子媒介杂志》2017,61(3):574-596

News use and political discussion are often studied as important factors in understanding the effects of political efficacy on participation. However, measurements of external efficacy often blur distinctions between personal ability and government responsiveness. This study establishes a measure for perceptions of competence in the institutions of democratic government—government efficacy (GE). Drawing on panel survey data from the United States, confirmatory factor analysis introduces GE as a unique construct. Political efficacy dimensions are tested for their impact on news consumption, discussion, and political participation. Results add to the extant literature revolving the role of political efficacy on news use, discussion, and participation.  相似文献   

Maximizing and assessing a one-shot information literacy session: A case study     

Esther L. Gil 《Journal of Business & Finance Librarianship》2017,22(2):97-110

This case study describes collaboration between an instructor and business librarian to maximize a one-shot information literacy session for a required marketing class for business majors. It includes an active-learning exercise where groups use three key business databases to conduct a company and industry analysis and an environmental scan for a company. The instructor then guides them in developing a strengths, weaknesses, opportunities, threats (SWOT) analysis. This session prepares students for the SWOT analysis they will have to submit for their actual projects. This article includes assessment of groups' in-class exercises as well as citation analysis of the assignments they turned in for their actual projects.  相似文献
