Social network innovation in the Internet’s global coffee houses: designing a mobile Help Seeking tool in Learning Layers     

John Cook  Patricia Santos 《Educational Media International》2014,51(3):199-213

In this paper, we argue that there is much that we can learn from the past as we explore the issues raised when designing innovative social media and mobile technologies for learning. Like the social networking that took place in coffee houses in the 1600s, the Internet-enabled social networks of today stand accused of being the so-called “weapons of mass distraction” or worse. However, we point out that modern fears about the dangers of social networking are overdone. The paper goes on to present some of the 1930s ideas of Vygotsky. Part of the Learning Layers project builds on this work; we report on extensive initial co-design work and significant barriers with respect to the design of a mobile Help Seeking tool for the health care sector (UK). We then provide an account of how the Help-Seeking tool is being linked to a Social Semantic Server and briefly report on a follow-up empirical co-design study. We conclude by highlighting associated challenges.  相似文献

Returning to the mirror: reflections on promoting constructivism in three educational contexts     

Alison Cook‐Sather 《Cambridge Journal of Education》2008,38(2):231-245

Since the early 1980s educators have argued that reflection is an essential dimension of good pedagogical practice. This discussion of my attempt to support a constructivist approach to learning for three different groups of learners illustrates one effort to engage in such reflection. I analyze several assignments I have designed for differently positioned learners, all within the context of a liberal arts college in northeastern USA. Referring to the assignments I have developed in each context, I analyze the particular kinds of structures, challenges and supports I try to provide to learners, with the goal of surfacing the convictions I hold about learners' identities and capabilities. My intention is to identify underlying pedagogical principles that inform my practice across contexts, not only to make it clearer for myself and others what guides that practice but also, in an effort to acknowledge the evolving and interdependent nature of this work, to articulate the new challenges this analysis poses for me.  相似文献   

Realizing the Value of Non-Purchased Content     

Elyse Profera  Meg Walker  Eleanor I. Cook 《期刊图书馆员》2014,66(1-4):88-91

This presentation summarized a May 2013 white paper published by Taylor & Francis Group, Facilitating access to free online resources: challenges and opportunities for the library community (www.tandf.co.uk/libsite/pdf/TF-whitepaper-free-resources.pdf). Taylor & Francis staff conducted research aimed at exploring free content discoverability from the perspective of librarians. Study focus groups were held in London and Seattle, Washington in early 2013. Research also included telephone interviews, surveys, and literature searching to identify relevant studies and commentary articles.  相似文献   

Is salivary cortisol moderating the relationship between salivary testosterone and hand-grip strength in healthy men?     

Blair T. Crewther  Andrew G. Thomas  Steve Stewart-Williams  Liam P. Kilduff  Christian J. Cook 《European Journal of Sport Science》2017,17(2):188-194

This study examined the moderating effect of cortisol (C) on the relationship between testosterone (T) and hand-grip strength (HGS) in healthy young men. Sixty-five males were monitored for salivary T, C and HGS before and 15?min after a short bout (5?×?6-s trials) of sprint cycling exercise. Sprint exercise promoted (p?<?.05) positive changes in T (6.1?±?24.9%) and HGS (3.4?±?7.5%), but a negative C response (?14.4?±?33.1%). The T and C measures did not independently predict HGS, but a significant T?×?C interaction was found in relation to these outcomes. Further testing revealed that pre-test T and HGS were negatively associated (p?<?.05), but only in men with high C levels. The exercise changes in T and HGS were also negatively related in men with low C levels (p?<?.05), but no relationship was seen in men with high C levels. In summary, complex relationships between T and HGS emerged when considering C as a moderating variable. The pre-test combination of high C and low T levels favoured absolute HGS, whereas low pre-test C levels and a smaller T change were linked to larger HGS changes. These associations suggest that, in the current format, T is not necessarily anabolic to muscle strength in healthy young men. Such complexities could also explain some of the inconsistent T relationships with physical performance in lesser trained male populations.  相似文献

The effect of recovery strategies on physical performance and cumulative fatigue in competitive basketball     

Montgomery PG  Pyne DB  Hopkins WG  Dorman JC  Cook K  Minahan CL 《Journal of sports sciences》2008,26(11):1135-1145

To evaluate the effectiveness of recovery strategies on physical performance during a 3-day tournament style basketball competition, 29 male players (mean age 19.1 years, s= 2.1; height 1.84 m, s= 0.34; body mass 88.5 kg, s= 14.7) were assigned to one of three treatment groups: carbohydrate+stretching (7.7 g kg(-1) day(-1), s= 1.7; 'n = 9), cold water immersion (11 degrees C, 5 x 1; n = 10) or full leg compression garments (18 mmHg, approximately 18 h; n = 10). Effects of the recovery strategies on pre-post tournament performance tests were expressed as the mean change (% +/- standard deviation of the change score). Changes and differences were standardized for accumulated game time, assessed against the smallest worthwhile change for each test, and reported qualitatively. Accumulated fatigue was evident over the tournament with small to moderate impairments in performance tests. Sprint and agility performance decreased by 0.7% (s = 1.3) and 2.0% (s = 1.9) respectively. Vertical jump decreased substantially after the first day for all treatments, and remained suppressed post-tournament. Cold water immersion was substantially better in maintaining 20-m acceleration with only a 0.5% (s = 1.4) reduction in 20-m time after 3 days compared with a 3.2% (s = 1.6) reduction for compression. Cold water immersion (-1.4%, s = 1.7) and compression (-1.5%, s = 1.7) showed similar substantial benefits in maintaining line-drill performance over the tournament, whereas carbohydrate+stretching elicited a 0.4% (s =1.8) reduction. Sit-and-reach flexibility decreased for all groups, although cold water immersion resulted in the smallest reduction in flexibility. Basketball tournament play elicited small to moderate impairments in physical test performance. In conclusion, cold water immersion appears to promote better restoration of physical performance measures than carbohydrate + stretching routines and compression garments.  相似文献   

The nature of static friction     

Walter Claypoole  Donald B. Cook 《Journal of The Franklin Institute》1942,233(5):453-463

The factors concerned in friction are discussed, together with a review of the limitations of the various approaches heretofore used. A more satisfactory view of the basic cause of static friction is developed in relation to modern experimental knowledge by considering the pertinent factors in systems having ideal surfaces, then relating this discussion to conditions in the best obtainable practical situation.  相似文献
