On the analysis of nonlinear stochastic systems

A comparison is given of two exact methods for the analysis of nonlinear systems with stochastic input and stochastic parameters: the Taylor-Cauchy Transform method and the Volterra-Wiener Functional method. The final results check with each other. Examples are provided.     

西藏蔷薇科植物的区系特点和地理分布

The Rosaceae is one of the five largest families of Xizang flora,  consisting of 30 genera with 242 species,  the total number of species is slightly less than those of Compositae,  Graminae,  Leguminosae and Ericaceae in Xizang,  amounting to 62.5% of the total number of genera and 28% of the total number of species of the rosaceous flora in China.       The four subfamilies of Rosaceae including primitive,  intermediate and advanced groups have been found in Xizang.  These groups consist of 11 types of floristic ele- ments,  i.e. 4 genera belong to cosmopolitan,  9 genera belong to North Temperate,  3,  E. Asian-N.  American,  3 Sino-Himalayan,  3 Sino-Japanesa,  2 Old World Temperate,  1 Temperate Asian,  2 Mediterranean-W. and O. Asian,  1 C. Asian,  I Tropical Asian and 1 endemic to China. It is obvious that Rosaceae in Xizang comprises holarctic,  Ancient Me- diterranean and paleotropical elements,  among which the temperate components are the most dominant.  The characteristics of the floristic composition of Rosaceae in Xizang may be summarized as follows:       (1) Xizang abounds in both genera and species of the family which are diverse in forms,  including the primitive,  intermediate and advanced groups, (2) The geographi- cal elements are rather complex,  mostly belonging to the temperate,  among which the Sino- Himalayan components and the elements endemic to China are dominant, (3) The proportion of plants endemic to China and distributed in Xizang is much higher than those endemic to Xizang itself,  but there exist newly arisen species and infraspecific forms or varieties which show that the speciation is apparently still active in Xizang. The rosaceous flora of Xizang is a combination of old and new floristic elements,  based on the old floristic components,  affected by the upheaval of the Himalayas,  the differen- tiation and speciation have been taking place in the long history.       The geographical distribution of Rosaceae in Xizang may be divided into 5 regions, i.e. the northeastern,  southeastern,  southern,  northwestern and northern.  The rosaceous plants are most abundant in the southeastern area,  next in southern area,  fewer in the northeastern and very rare in the northwestern and northern regions.  The general ten- dency of the distribution of Rosaceae in Xizang is that the number of species gradually decreases from the southeast to the northwest and the habit gradually changes from trees,  shrubs and herbaceous plants in the southeast to cushion-like scrubs and dwarf perennial herbs in the northwest.  These facts clearly show that the uplift of the Hi- malayas has deeply affected the phytogeographical distribution of Xizang Rosaceae.       The rosaceous flora of Xizang has close relationships with those of the adjoring regions,  i.e. Yunnan and Sichuan.  Besides,  it is connected with floras of Nepal,  Sikkim, Bhutan nothern Buram and nothern India,  but silghtly influenced by the Ancient Medi- terranean flora.

促进图书馆实践2.0服务的策略——基于焦点团体的实证研究

内容聚合、维基百科、社会媒体、博客和即时通讯等Web2.0工具对图书馆而言是极好的服务系统。此实证研究面世过焦点团体的三项成果,包括采购系统、使用系统服务和绩效考核,来讨论用政策的、战略的与战术的模式使用Web 2.0工具作为服务2.0应用的情况。然而,这套服务模式存在许多限制,因此我们建议在众多未来案例研究的基础上创建与使用型人来强化目标导向的数字化服务。

图书馆的四个文明

认为图书馆文明包括4个方面：①知识在媒体上的记忆储存;②知识媒体的再现流通与传递;③知识内容的参考与转介服务;④知识内涵与知识表现的管理。从文明性质、社会功能等方面对图书馆4个文明进行比较,指出在图书馆创建文明的同时,需及时解决伴随环境变化而衍生的各种矛盾。     

Personalization of mathematics word problems in Taiwan

This study investigated the effects of group personalization of instruction on the mathematics achievement and attitudes of 72 fifth-grade Taiwanese students. Personalization was accomplished by incorporating personal information and preferences provided by students into their mathematics word problems. Students were blocked by ability level, then randomly assigned to a personalized or nonpersonalized version of an instructional program on mathematics word problems. Students made significant pretest-to-posttest gains across treatments and scored significantly higher on personalized than on nonpersonalized posttest problems. However, the personalized treatment did not produce a significant achievement difference over the nonpersonalized one. Significant two-way interactions reflected greater pretest-to-posttest improvement for lower-ability than for higher-ability students and a greater difference between scores on personalized over nonpersonalized posttest problems for lower-ability students. The posttest scores of high-ability students were limited by a ceiling effect. Student attitudes were significantly more favorable toward the personalized instruction.
