This article draws on ethnographic fieldwork that took place in 2004 in a boys’ hifz class which met in a north‐east London mosque. Drawing on the results of semi‐participant observations and semi‐structured interviews, the research findings are collated under five themes: the routines and rhythms of the hifz class; routes into the hifz class; the students’ perceptions of what they were doing; the ‘sacrifice’ of becoming a hafiz; and hifz class and the rest of students’ lives. Though the analysis is largely of the subjective responses of hifz class members and cannot therefore give definitive answers to research questions, the author points to some of the implications of this work and offers pointers for further research work in this field.  相似文献

Running is the most important discipline for Olympic triathlon success. However, cycling impairs running muscle recruitment and performance in some highly trained triathletes; though it is not known if this occurs in elite international triathletes. The purpose of this study was to investigate the effect of cycling in two different protocols on running economy and neuromuscular control in elite international triathletes. Muscle recruitment and sagittal plane joint angles of the left lower extremity and running economy were compared between control (no preceding cycle) and transition (preceded by cycling) runs for two different cycle protocols (20-minute low-intensity and 50-minute high-intensity cycles) in seven elite international triathletes. Muscle recruitment and joint angles were not different between control and transition runs for either cycle protocols. Running economy was also not different between control and transition runs for the low-intensity (62.4 +/- 4.5 vs. 62.1 +/- 4.0 ml/min/kg, p > 0.05) and high-intensity (63.4 +/- 3.5 vs. 63.3 +/- 4.3 ml/min/kg, p > 0.05) cycle protocols. The results of this study demonstrate that both low- and high-intensity cycles do not adversely influence neuromuscular control and running economy in elite international triathletes.  相似文献

This paper examines a controversial research programme aimed at the production of transgenic cows in New Zealand. It emphasizes the contested representation of the research, in its promotion, in its governance, and in the opposition sparked amongst environmentallanti-genetic modification groups and within the Māori community. The paper contends that the case of New Zealand's genetically modified cows certainly reveals some unique features of the prevailing economic, geographical and cultural context, but nonetheless has salience for the broader understanding of the promotion, public reception and governance of genetic modification.  相似文献

Rats confronted with the onset of a light gradient display a transient increase in locomotion called theactivity response (AR) and a dark preference (Godsil & Fanselow, 2004). These experiments demonstrate that the magnitude of the AR can be blunted with Pavlovian fear-conditioning procedures via associative and nonassociative fear. Although manifested in decreased locomotion, the blunted AR effect was not due to increased freezing or immobility behaviors. Instead, rats displayed reduced rearing and an increase in a class of behaviors calledstationary activity. These results suggest that the lighting differential supplied by the cue influences the topography of defensive behavior and reduces the expression of freezing. This procedure provides a means by which to examine learned and unlearned defensive responses to the same stimulus.  相似文献

A concise review is presented of the essential elements of the book publishing and bookselling business in a complex and diverse market. Demographics create the diversity while Arabic is the one language spoken across a multitude of different countries. Three features are common to all of these countries and they are: the dominance of English as the second language, education has and will remain to be a priority, and economic pressures cause price sensitivity to be a major challenge especially in the educational market segments. It is the price sensitivity as a key factor for the lack of respect for intellectual property and copyright regulations. A review of distribution and retail stores is a very important topic in relation to this complex collection of countries. The emergence of e-books is discussed especially in the educational, professional and reference market segments. Finally, there is a review of the Arabic language publishers and local book fairs to bring this article to closure.  相似文献
