Helsen, Gilis and Weston (2006) err in testing the optical error hypothesis

In this commentary, we react to the recent study by Helsen, Gilis and Weston (2006) on judging offside in football. Helsen et al. claim that their data falsify the optical error hypothesis presented by Oudejans et al. (2000). However, as we will elucidate here, they misinterpret this hypothesis and present a data set that is seriously flawed, and hence not suited to test it. Therefore, their conclusions regarding the optical error hypothesis are in error.

试析美国的特许学校

特许学校（charter school）是20世纪90年代美国中小学教育领域出现的一种新型学校,体现了美国教育改革的新思路,因而引起了美国上至政府,下至百姓的普遍关注。丈章从特许学校的缘起及其迅速发展的原因、当前面临的问题与挑战等方面进行了论述,以期对我国目前办学形式的多样化提供新的视角和启示。     

生活方式干预对心血管疾病危险因素的影响——美国HELPS项目成果

摘要：心血管疾病（CVD）一直是全世界最主要的死因。由于CVD等慢性疾病对健康的威胁越来越大,有必要开展生活方式干预项目以控制这些疾病的危险因素。本研究的目的是评估美国的重要慢病干预项目—HELPS治疗型生活方式改变（TLC）项目对减少CVD危险因素和其他慢性疾病的有效性。方法：140位大学教职工参加为期12周的HELPS TLC项目,干预前后用配对t检验对其体重、BMI、腰围（WC）、6分钟步行距离（6MWD）、空腹血脂和血糖进行测定和比较。结果：干预后6MWD显著增加,总胆固醇（TC）和WC显著下降。对“高危”参与者进一步分析显示：BMI（-1.5±0.5,-3.9%）、TC（- 22.8±4.0,-9.0%）、LDL（- 14.1±4.9,9.3%）和血糖（-6.9±2.2,-6.1%）均显著下降;男性腰围（-4.5±0.8,-10%）显著减小,女性未见显著改变（-1.5±0.5,-4.0%）。此外,体重的变化与TC（r=0.43）、LDL（r=0.35）和血糖（r=0.44）的变化均显著相关。结论：参加12周的生活方式干预项目可以使CVD危险因素减少,特别是在CVD“高危”个体中。HELPS TLC项目的远期效果还待进一步深入研究。     

Peking University Launches a New Five-Year Project for the Development of Kunqu Opera

China＇s Kunqu Opera was included in the UNESCO List of Masterpieces of Oral and Intangible Cultural Heritage in 2001. As a traditional form of Chinese theatre, Kunqu Opera has not been widely known by overseas audiences. When European opera is presented worldwide and attracting numerous audiences, Chinese Kunqu Opera, enjoying equal artistic value, should also access Jbreign audiences.     

Practical Applications as a Source of Credibility: A Comparison of Three Fields of Dutch Academic Chemistry

In many Western science systems, funding structures increasingly stimulate academic research to contribute to practical applications, but at the same time the rise of bibliometric performance assessments have strengthened the pressure on academics to conduct excellent basic research that can be published in scholarly literature. We analyze the interplay between these two developments in a set of three case studies of fields of chemistry in the Netherlands. First, we describe how the conditions under which academic chemists work have changed since 1975. Second, we investigate whether practical applications have become a source of credibility for individual researchers. Indeed, this turns out to be the case in catalysis, where connecting with industrial applications helps in many steps of the credibility cycle. Practical applications yield much less credibility in environmental chemistry, where application-oriented research agendas help to acquire funding, but not to publish prestigious papers or to earn peer recognition. In biochemistry practical applications hardly help in gaining credibility, as this field is still strongly oriented at fundamental questions. The differences between the fields can be explained by the presence or absence of powerful upstream end-users, who can afford to invest in academic research with promising long term benefits.     

The Ultimate Beneficiaries of Continuing Professional Development Programs: Middle School Students’ Nature of Science Views

The effective continuing professional development (CPD) programs primarily aim to have an impact on teachers’ knowledge bases, beliefs, and views and their classroom practices, which rationally lead most of the researchers to investigate those changes on teachers primarily. Although neglected, the interrelationship between CPD programs and students is considered complex, and CPDs ultimately aim to have an impact on students’ views, too. Therefore, the purpose of this study is to survey the changes of middle school students’ views of the nature of science (NOS) by providing a large-scale CPD to their teachers and, in other words, identify the impact of CPD on ultimate beneficiaries, namely students. In this study, 10 science teachers’ data and, in the first phase, 481 and, in the second phase, 422 students’ data and the changes in their NOS views were analyzed. Results showed that the students’ and teachers’ NOS views changed positively. For the impact of teachers on the students’ views, the teachers’ prior NOS knowledge, years of experience, and the number of implemented activities were found to be the influential factors for the transmission of NOS views.
