Spatial sampling in the presence of a trend

The spatial sampling designs suggested by Quenouille (1949) are investigated under a number of trend assumptions, namely a linear trend, linear trend and periodic variation, and spatially correlated populations. The results obtained provide a planar analogue to the one-dimensional results appearing in Cochram (1977, Ch. ε). Centrally located systematic sampling and the planar analogue of Yates' (1948) method of end corrections are put forward as methods which eliminate the linear trend. The comparisons of the two methods provide the planar analogue to results obtained by Bellhouse and Rao (1975).     

未成年犯社区矫正的几点思考

对未成年犯进行社区矫正,是近年来世界各国刑罚执行制度的一个发展趋势。目前。在我国社区矫正试点工作中,罪行轻微、主观恶性不大的未成年犯罪人被确定为社区矫正的重点对象之一。对未成年犯进行社区矫正,有利于对未成年犯的再社会化,能够有效地克服对未成年犯监禁刑罚的弊端,有利于合理配置未成年犯行刑资源.我国未成年犯社区矫正的。实践刚刚开始,推进试点工作首先应当着力于相关法律的完善,其次,各地在试点工作中还应当选择适合未成年犯特点的社区矫正项目。     

The Organization of Corrective Demonstrations Using Embodied Action in Sports Coaching Feedback

Focusing on video recordings of coaching sessions in the context of basketball and powerlifting, this paper investigates how the sports coaching process unfolds as situated interactions. The work of sports coaching is pervasively oriented toward teaching athletes the correct forms of motion and play. Correction then is one of the central constitutive practices of sports training sessions. In this paper, we draw on a collection of instances of correction demonstrations from powerlifting and basketball to describe their order. We demonstrate the three phases of these demonstrations: arranging bodies and gaze for visual access, presenting the error visually, and proposing a correction with an embodied demonstration. Findings underscore the management of shared visual access in multi‐party correction demonstrations. In demonstrating how multiple bodies may be involved in embodied reenactments of a correctable problem, and demonstrating that it is seeing an error, more than reenactment per se, that is necessary for correction activities, the study extends existing understandings both of sports coaching processes and of instructional correction in embodied activities.     

论朱熹《孝经刊误》的影响

本文从《孝经》研究史及文献学的角度 ,对南宋前后的《孝经》研究实况作了扼要考察 ,认为朱熹《孝经刊误》的出现 ,打破了唐末至北宋《孝经》研究的沉寂状态 ,使疑经与编外传成为两大潮流 ,影响了后世近 5 0 0年。并对这种影响作了辩证分析 ,以期校正古今学术界对此书在认识上存在的“过”与“不及”两种偏见。
