This work describes the genesis, articulation and consolidation from 2007 of a social network of b-learning (blended learning) in the UA (University of Alicante) (Spain), with the institutional backing of the Office of the Vice President for Education Technology and Innovation, and the momentum and advice of professor Angel Fidalgo (UNESCO (United Nations Educational, Scientific and Cultural Organization) chair for University of Management and Policy). The social network currently has more than 25 teachers, working on different work linkages with the university, implementing or intending to apply the teaching methodologyb-learning during the course 2007-2008 in a variety of courses and degrees. To do so, several resource centers (blogs, wikis, Wimba Create (before CourseGenie), etc.), and digital platforms (Virtual Campus of the UA, Moodle, etc.) are used. 相似文献

In a series of related experiments, we studied associative phenomena in snails (Helix aspersa), using the conditioning procedure of tentacle lowering. Experiments 1A and 1B demonstrated a basic conditioning effect in
which the pairing of an odor (apple) as the conditioned stimulus (CS) with the opportunity to feed on carrot as the unconditioned
stimulus (US) made snails exhibit increased levels of tentacle lowering in the presence of the CS. Experiments 2 and 3 showed
that the magnitude of the conditioning was reduced when snails were exposed to the CS prior to the conditioning trial (a latent
inhibition effect). Experiment 4 examined the effects produced by pairing a compound CS (apple—pear) with food presentations
and demonstrated the existence of an overshadowing effect between the two odors. Experiment 5 revealed that pairing one CS
with another previously conditioned stimulus increased tentacle lowering to the new CS (a second-order conditioning effect).
Finally, Experiment 6 showed that pairing two odors prior to conditioning of one of them promoted an increase in tentacle
lowering in response to the other (a sensory preconditioning effect). The results are discussed in terms of an associative
analysis of conditioning and its implications for the study of cognition in invertebrates. 相似文献

Although bike fitting is recommended to help reduce injury risk, little empirical evidence exists to indicate an association between bike fitting and injury incidence. The aim of the study was to determine the effect of bike fitting on self-reported injury, comfort, and pain while cycling from a worldwide survey of cyclists. A total of 849 cyclists completed an online questionnaire between February and October 2016. Questionnaire collected data on respondent demographics, cycling profile, bike fitting, comfort and pain while cycling, and injury history. The main predictor variable was bike fitting (yes, by the respondent, i.e. user bike fitting; yes, by a professional service; or no). Covariates included demographic and cycling profile characteristics. Logistic regression models estimated the odds of injury within the last 12 months, reporting a comfortable body posture while cycling, and not reporting pain while cycling. Odds ratios (OR) with 95% confidence intervals (CI) were reported. User bike fitting was associated with increased odds of reporting a comfortable posture (OR?=?2.28, 95%CI: 1.06, 4.68). User (OR?=?2.35; 95%CI: 1.48, 3.84) and professional bike fitting (OR?=?2.35; 95%CI: 1.42, 3.98) were both associated with increased odds of not reporting pain while cycling. No associations were found between bike fitting and injury within the last 12 months. In conclusion, we found an association between bike fitting and reported comfort and pain while cycling. We recommend integrating bike fitting into cycling maintenance. However, further studies with longer follow-up are necessary to determine the presence of an association between bike fitting and injury. 相似文献

This study investigated adult attachment and acculturation frameworks of reported psychosomatic complaints related to perceived discrimination among a sample of Latino/Hispanic university students (N = 160). The model supported by the data suggests that attachment anxiety, acculturation toward the dominant cultural norms, and adherence to Latino/Hispanic cultural beliefs are important factors for perceived discrimination and psychosomatic complaints experienced by Latino/Hispanic students. Counseling implications and future research directions are discussed. 相似文献

We develop natural language processing techniques to identify the creation and impact of new technologies in the population of U.S. patents. We validate the new techniques and their improvement over traditional metrics based on patent classification and citations in two case-control studies. First, we collect patents linked to awards such as the Nobel prize and the National Inventor Hall of Fame. These patents likely cover radically new technologies with a major impact on technological progress and patenting. Second, we identify patents granted by the United States Patent and Trademark Office but simultaneously rejected by both the European and Japanese patent office. Such patents arguably lack novelty or cover small incremental advances over prior art and should have little impact on technological progress. We provide open access to code, data, and new measures for all utility patents granted by the USPTO up to May 2018 (see https://zenodo.org/record/3515985, DOI: 10.5281/zenodo.3515985). 相似文献

In this paper, we deploy M.M. Bakhtin’s notions about how language works to understand aspiring teachers’ struggles about the intersecting roles race, class, gender, language background, and sexual orientation play in students’ school lives and learning. Through life-history interviews and document analysis, we investigated the authoritative and internally persuasive discourses one aspiring teacher brought with her and took from a 15-week long course on a predominantly White Midwestern public university campus. Ideas she encountered in the course and its required tutoring component challenged her thinking about how various facets of people’s lives (such as those we list above) and the contexts in which they live, work and are schooled, affect how they are perceived, what they know, and can do. 相似文献

The aim of this study was to examine the effect of playing formation on high-intensity running and technical performance during elite soccer matches. Twenty English FA Premier League games were analysed using a multiple-camera computerized tracking system (n = 153 players). Overall ball possession did not differ (P < 0.05) between 4-4-2, 4-3-3 and 4-5-1 formations (50%, s = 7 vs. 49%, s = 8 vs. 44%, s = 6). No differences were observed in high-intensity running between 4-4-2, 4-3-3 and 4-5-1 formations. Compared with 4-4-2 and 4-3-3 formations, players in a 4-5-1 formation performed less very high-intensity running when their team was in possession (312 m, s = 196 vs. 433 m, s = 261 vs. 410 m, s = 270; P 5 0.05) but more when their team was not in possession (547 m, s = 217 vs. 461 m, s = 156 vs. 459 m, s = 169; P < 0.05). Attackers in a 4-3-3 performed ~30% more (P < 0.05) high-intensity running than attackers in 4-4-2 and 4-5-1 formations. However, the fraction of successful passes was highest in a 4-4-2 (P < 0.05) compared with 4-3-3 and 4-5-1 formations. The results suggest that playing formation does not influence the overall activity profiles of players, except for attackers, but impacts on very high-intensity running activity with and without ball possession and some technical elements of performance. 相似文献
