NEAR-ALGEBRA和BANACH代数上的一个特征值定理(英文)

在near-algebra或Banach代数中引入(p,q)-可加自映象f和正则可逆元的概念,得到一个值得注意的结果,即在一定条件下,对于定义在near-algebra或Banach代数X中(p,q)-可加自映象f,X中的任意正则可逆元都具有公共的特征值λ=2q/(1 q),p=q≠?1。     

In Memoriam: Emeritus Professor Henry Oliver Lancaster, AO FAA 1 February 1913 – 2 December 2001

The death, in Sydney, of Oliver Lancaster marks the end of an era in the histories of the Statistical Society of Australia, which (in its previous existence as the Statistical Society of New South Wales) he helped found in 1947, and of the Australian Journal of Statistics of which he was founding editor (1959–1971). Oliver Lancaster was Foundation Professor of Mathematical Statistics at the University of Sydney (1959–1978), where he spent his life as student and academic. During his academic career, he achieved scholarly distinction in at least four fields: mathematical statistics, medical and public health statistics, the history of medicine and of statistics, and statistical bibliography. With E.J.G. Pitman (1897–1993), M.H. Belz (1897–1975), E.A. Cornish (1909–1973) and P.A.P. Moran (1917–1988) he was part of a cohort of renowned Australian mathematical statisticians who laid the foundation of the glory days of Australian mathematical statistics. This obituary and tribute focuses on some of these aspects, within a broader historical picture.

A Unified Approach to the Approximation of Multivariate Densities

Approximation of a density by another density is considered in the case of different dimensionalities of the distributions. The results have been derived by inverting expansions of characteristic functions with the help of matrix techniques. The approximations obtained are all functions of cumulant differences and derivatives of the approximating density. The multivariate Edgeworth expansion follows from the results as a special case. Furthermore, the density functions of the trace and eigenvalues of the sample covariance matrix are approximated by the multivariate normal density and a numerical example is given     

新常态下供销社经营模式的转型与创新研究

随着我国新型四化的深入推进,农村经济建设迈入了新阶段。在新常态下,供销社的迫切任务是加快转型升级,切实提高为农服务能力。因而这就要求我们既要把握好传统业务,又要善用改革和创新的思维开拓新型业务,用业务经营发展促使供销社转型升级。面对我国经济发展新常态,供销社过去长期积累起来的服务“三农”的宝贵经验遇到了很大的挑战,在经营过程中所暴露出的经营方式、手段等方面都存在着很多弊端,进而阻碍了供销社的生存与发展。供销社要想走为农服务的道路,转型与创新势在必行。基于经济发展新常态,分析供销社在发展中存在的突出问题;研究供销社进行转型与创新的必要性;最后归纳总结供销社经营模式的创新途径。     

经史之学与清代书院科举文教育

清代书院官学化,很多书院重视科举。有些书院虽从事科举文教育,但不唯之是从,而是将科举文教育与经史之学教育结合起来。此举上溯于中国古代社会推崇经史之学的优良传统,根植于孔子“博学于文”的思想主张,来源于以学术导向矫正利禄歪风的迫切要求。生徒只有学充养邃,才会眼界高、气味厚、笔力健。清代一些书院将科举文教育与经史之学教育结合起来,使得生徒学文不是局限于写作技巧的训练,而是拓展为与炼品、践行、培识的结合。这些书院通过教育,能够为社会培养有用人才。     

苏赋十题

本文首为苏赋辨伪,认为《苏轼文集》所收苏赋27篇,有两篇非苏轼作品。次为苏赋编年,二至五题逐篇考订了苏赋的写作时间。再次为苏赋辨体,六至八题分别论述了苏轼的骚体赋、律赋和文赋,认为苏赋诸体皆备,苏轼以文赋闻名于赋史,但他的文赋并不多。九题论苏轼仍以骈赋为多,着重论苏赋分类,认为苏赋题材十分丰富,含议政、纪游、吊古、咏物,苏轼不善饮酒,而咏酒赋特多。十题是比较二苏赋之异同,苏辙现存赋仅9篇,远较苏轼为少,作《缸砚赋》时年仅17岁,比《赤壁赋》的写作时间早25年。其《服菔苓赋》在当时已传到契丹,其《黄楼赋》尤为有名,杨万里甚至把《黄楼赋》与前后《赤壁赋》相提并论。     

中学语文新课标情势下的高师院校中文系复合型人才的培养

21世纪,我国的中学语文课程标准提出了新的理念和要求。作为高等师范院校,如何培养中学语文新课标需要的复合型人才是一项复杂的系统工程。首先应建立起以科学的教育理念为基础,以多学科合作立体交叉的知识培养与加大教育实习基地实训相结合的培养模式;其次应采取措施,使学生在获取知识的同时,提高综合素质和实践能力。     

战略联盟的范围、治理与稳定性间关系的实证研究

本文从联盟伙伴间的关系视角出发,分析了战略联盟的合作范围和治理类型对伙伴间关系稳定性的影响.由于稳定性是一个抽象且难以用显性指标直接测量的变量,本文把它构建为一个二阶因子结构,并用企业间信任、相互依赖和冲突解决这三个一阶因子来度量它.在此基础上,通过问卷调查获得127家德国联盟企业的数据,并对提出的假说进行了检验,分析结果表明合资企业比非股权契约联盟更有可能享有稳定的伙伴间合作关系,而联盟的范围即联盟协议中所包含的合作活动的多少对联盟稳定性没有显著的影响.
