Variations in Variation and Selection: The Ubiquity of the Variation-and-Selective-Retention Ratchet in Emergent Organizational Complexity, Part II: Quantum Field Theory

If the general arguments concerning theinvolvement of variation and selection inexplanations of ``fit'' are valid, then variationand selection explanations should beappropriate, or at least potentiallyappropriate, outside the paradigm historisticdomains of biology and knowledge. In thisdiscussion, I wish to indicate some potentialroles for variation and selection infoundational physics – specifically inquantum field theory. I will not be attemptingany full coherent ontology for quantum fieldtheory – none currently exists, and none islikely for at least the short term future. Instead, I wish to engage in some partiallyspeculative interpretations of some interestingresults in this area with the aim ofdemonstrating that variation and selectionnotions might play a role even here. Ifvariation and selection can survive in even asinhospitable and non-paradigmatic a terrain asfoundational physics, then it can surviveanywhere.     

高师大学生体育行为调查与研究

采用问卷调查、数理统计和文献资料法对六所不同地区的高师非体育专业不同专业和各年级师范类大学生的体育行为进行了调查研究。结果表明,影响高师大学生体育行为形成的最主要因素是对体育运动的兴趣;对体育运动的价值取向主要是增进身心健康;对参加体育运动的频率调查显示当前高师大学生参加体育运动的状况并不很理想,只偶尔参加体育运动的同学占调查者的四分之一多;大学生最常参加的体育运动项目主要是球类项目;影响同学参加体育锻炼的主要因素是体育运动场地和器材的缺少;高师大学生最需要提高的体育能力是科学锻炼能力。

区域经济发展不平衡对义务教育投入的影响

地区经济发展不平衡是我国的一个基本国情，上世纪90年代义务教育投资总量和人均教育经费投入水平在我国三大地带呈现巨大差距，其成因是多方面的，要改变这种状态，必须建立规范的政府间基础教育财政支付制度，对政府管理基础教育的层级进行调整，建立农村义务教育教师工资保障机制。     

Environmental Friendly Route and Wool Shrink Proofing

The shrink proofing on wool with treatment of protease named Argaenzyme STL was studied. The various pretreating auxiliaries, different parameters for protease treating process and the effect of stabilizer were discussed in detail. The varieties of some properties before and after protease treatment were also investigated.
