This short bibliography is not supposed to be a comprehensive survey of all that has been written about gender and science. Its much more modest aim is to mention a few of the many books that have been published on this subject in recent years, and to give some indication of their contents. By doing this I hope to provide readers with a starting point from which to pursue an interest in any particular aspect of the subject. 相似文献

This study assessed changes in selected physiological and kinematic variables over 6 weeks of treadmill skating in an effort to understand the process of habituation to this novel training modality. Seven male, Atom-A hockey players who were injury-free and had no previous treadmill skating experience participated in the study. Players performed four 1-min skating bouts at progressively increasing speeds, each week, for 6 weeks. One speed (10.5 km/h) was repeated weekly to allow for assessment of the habituation process. Our criteria for habituation were: a decrease in stride rate, heart rate and rating of perceived exertion, and an increase in stride length, trunk angle and vertical movement of the centre of mass, leading to a plateau, over the course of the 6-week study. Significant decreases were seen in stride rate, heart rate and ratings of perceived exertion, and significant increases were found in stride length. Some of these changes were evident after only one week of training and all were present by week 4. After 6 weeks (24 min) of exposure to treadmill skating, all participants displayed a visibly more efficient skating style. 相似文献

This study examined how activity type influenced heart rates and time spent in target heart rate zones of high school students participating in physical education classes. Significantly higher average heart rates existed for fitness (142 +/- 24 beats per minute [bpm]) compared to team (118 +/- 24 bpm) or individual (114 +/- 18) activities. Similar results occurred for the percentage of activity time spent within a target heart rate zone (fitness 81.7 +/- 15.9%, individual 68.4 +/- 30.5%, and team 60.6 +/- 30.5%). Boys attained higher heart rates during team activities, while female students had higher rates during individual activities indicating male and female adolescents respond differently to activity types. The highest mean heart rates were observed during fitness activities. 相似文献

Geographic clustering of economic activity: The case of prominent western visual artists 总被引：1，自引：1，他引：0
This article compiles original data relating to artists’ place of birth and work migration patterns using various art history
dictionaries. The broad historic pattern, from the 13th to the 20th century, of the birth locations of prominent artists is examined, followed
by a detailed study of the work migration patterns of prominent artists in two important situations, namely Renaissance Italy
and France in part of the 19th century. The evidence indicates a marked clustering of activity of prominent artists, both
arising from birth location and migration patterns. Some possible explanations for the observed patterns are briefly outlined.

Hybrid Journals: Ensuring Systematic and Standard Discoverability of the Latest Open Access Articles
An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs. 相似文献
