Learning to use the Internet as a study tool: a review of available resources and exploration of students' priorities

BACKGROUND: The Internet is a valuable information tool, but users often struggle to locate good quality information from within the vast amount of information available. OBJECTIVE: The aim of the study was to identify the online information resources available to assist students develop Internet searching skills, and to explore the students' priorities in online guides. METHODS: A qualitative approach was adopted with two phases. The first was a structured search of available online study skills resources. The second comprised 10 group interviews with a total of 60 students at all stages of five undergraduate health and social care related courses at a UK university. RESULTS: The study found that there were good online guides available, but that, perversely, the better guides tended to require the best searching skills to locate them. A few students were enthusiastic about using online support, however the majority felt that if they had the skills to locate such resources they wouldn't use a study guide to improve these skills, and if they did not have the skills they would not think of using an online guide to develop them. CONCLUSIONS: Students wanted assistance when they had problems or questions, rather than sites that offered structured learning experiences. Personal support rather than virtual support was also considered to be most important to the students in this study.     

Differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during treadmill running

The aims of this experiment were to determine whether there are differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during running and, if such differences exist, to establish whether factors other than sex can explain the observed differences. A cohort of 44 non-injured runners (22 males, 22 females) who usually ran more than 20 km per week were voluntarily recruited. All trials were conducted on a treadmill at a running speed of 4.0 m x s(-1). Reflective markers were placed over specific anatomical landmarks of the thoraco-lumbar spine, pelvis and femur. Data were captured using a VICON motion analysis system. Females tended to display a greater peak-to-peak oscillation for most of the angular rotations. An offset was the main difference between the male and female group mean waveforms for pelvis anterior-posterior tilt. Forward stepwise regression analysis revealed that sex was the most common variable related to the amplitudes of the angular rotations. Given these results, sport scientists conducting future biomechanical studies using angular data to test hypotheses are advised to be extremely cautious about averaging across male and female participants.     

丹麦的科学普及及其与妇女的关系

今天,在丹麦,科学技术正在通过各种渠道进行普及。各种形式的夜校、杂志、书籍和电视节目使公众对科学的兴趣日益增加,足以补传统科学学习方式的不足。为了使女孩学习科学技术,正在进行特殊的努力。妇女对生物学、化学和医学的兴趣已显示出显著的增加趋势,而计算机科学、物理学和技术仍是男人的领域。     

血样贮存对血乳酸浓度的影响

本文研究了贮存2～6周的血样乳酸浓度的变异性，采200米跑后即刻指尖血样，用EDTA，三硝基甲苯X－100溶血及NaF抗酵解处理，分别在采血后即刻2周，4周，6周对样本进行血乳酸分析，对各组数据进行方差分析F2216＝16．26P＜0．01，说明贮存6周以上对血乳酸浓度有显著性影响。
