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。

Sparse polynomials, redundant bases, gauss periods, and efficient exponentiation of primitive elements for small characteristic finite fields

Gauss periods give an exponentiation algorithm that is fast for many finite fields but slow for many other fields. The current paper presents a different method for construction of elements that yield a fast exponentiation algorithm for finite fields where the Gauss period method is slow or does not work. The basic idea is to use elements of low multiplicative order and search for primitive elements that are binomial or trinomial of these elements. Computational experiments indicate that such primitive elements exist, and it is shown that they can be exponentiated fast.

Non‐empirical calculations of NMR indirect carbon–carbon coupling constants. Part 4: Bicycloalkanes

A systematic study of the one‐bond and long‐range J(C,C), J(C,H) and J(H,H) in the series of nine bicycloalkanes was performed at the SOPPA level with special emphasis on the coupling transmission mechanisms at bridgeheads. Many unknown couplings were predicted with high reliability. Further refinement of SOPPA computational scheme adjusted for better performance was carried out using bicyclo[1.1.1]pentane as a benchmark to investigate the influence of geometry, basis set and electronic correlation. The calculations performed demonstrated that classical ab initio SOPPA applied with the locally dense Dunning's sets augmented with inner core s‐functions used for coupled carbons and Sauer's sets augmented with tight s‐functions used for coupled hydrogens performs perfectly well in reproducing experimental values of different types of coupling constants (the estimated reliability is ca 1–2 Hz) in relatively large organic molecules of up to 11 carbon atoms. Additive coupling increments were derived for J(C,C), J(C,H) and J(H,H) based on the calculated values of coupling constants within SOPPA in the model bicycloalkanes, in reasonably good agreement with the known values obtained earlier on pure empirical grounds. Most of the bridgehead couplings in all but one bicycloalkane appeared to be essentially additive within ca 2–3 Hz while bicyclo[1.1.1]pentane demonstrated dramatic non‐additivity of ?14.5 Hz for J(C,C), +16.6 Hz for J(H,H) and ?5.5 Hz for J(C,H), in line with previous findings. Non‐additivity effects in the latter compound established at the SOPPA level should be attributed to the through‐space non‐bonded interactions at bridgeheads due to the essential overlapping of the bridgehead rear lobes which provides an additional and effective non‐bonding coupling path for the bridgehead carbons and their protons in the bicyclopentane framework.

论高校与大学生的法律关系

随着市场经济的深入发展,人们法制观念的进一步增强,高等学校与大学生之间的纠纷层出不穷,两者之间的法律关系便成为众多学者研究和考察的对象。要理清高校与大学生之间的法律关系,首先必须明确二者以什么角色去建立法律关系。总结起来,高等学校作为法律法规授权的行政主体,与大学生建立的是行政法律关系;以教育教学的名义成为民事主体,与大学生建立的是民事法律关系;因作为集体利益的代言人成为集体法人,与大学生建立的是特别权力关系。
