布雷顿森林体系与美国霸权

战后美国的超级大国地位奠定了其作为布雷顿森林体系的主要设计师地位,美国得以在这一体系中贯彻其门户开放型新殖民主义的全球扩张战略。另一方面,布雷顿森林体系也是经济全球化趋势与国家垄断资本主义发展的产物,美国因此成为牵引全球化的火车头。美国主导之下的布雷顿森林体系进一步加强了美国的经济、政治霸主地位。     

美术教育让民族文化由"遗产"转向"资源"

在全球化的今天,要实现中华民族文化的繁荣,首先应客观了解我国民族文化形成过程中出现的多样性文化特点,实现文化自觉,坚定文化自信,才能真正激活民族性格中的文化基因。美术学科涉及中华民族物质文化与非物质文化的形态,从多样性文化的角度出发,通过引入图像学、艺术人类学等相关学科的专业知识与观察方法,将丰富的民族文化遗产实现当代文化资源的转变,在传承优秀民族文化的基础上拓展学生解决实际问题的创新能力,为美术学科实现社会价值提供更多样的思考。

语言理解及表达力先天发育水平表现因素研究

为了最大限度减少后天因素对语言理解及表达力先天发育水平的影响,以3岁幼儿为研究对象,在分析现有对语言理解及表达力研究的基础上,提出语言理解及表达力表现因素测评指标框架,依据其共性表现因素并结合3岁幼儿语言理解及表达力的个性表现,进行了测评指标实验研究。对西安地区不同水平幼儿园随机抽样的297名儿童进行测评,结果表明这种测评方法具有普适性与可操作性。     

Fungal diversity in adult date palm (Phoenix dactylifera L.) revealed by culture-dependent and culture-independent approaches

Endophytic flora plays a vital role in the colonization and survival of host plants, especially in harsh environments, such as arid regions. This flora may, however, contain pathogenic species responsible for various troublesome host diseases. The present study is aimed at investigating the diversity of both cultivable and non-cultivable endophytic fungal floras in the internal tissues (roots and leaves) of Tunisian date palm trees (Phoenix dactylifera). Accordingly, 13 isolates from both root and leaf samples, exhibiting distinct colony morphology, were selected from potato dextrose agar (PDA) medium and identified by a sequence match search wherein their 18S–28S internal transcribed spacer (ITS) sequences were compared to those available in public databases. These findings revealed that the cultivable root and leaf isolates fell into two groups, namely Nectriaceae and Pleosporaceae. Additionally, total DNA from palm roots and leaves was further extracted and ITS fragments were amplified. Restriction fragment length polymorphism (RFLP) analysis of the ITS from 200 fungal clones (leaves: 100; roots: 100) using HaeIII restriction enzyme revealed 13 distinct patterns that were further sequenced and led to the identification of Alternaria, Cladosporium, Davidiella (Cladosporium teleomorph), Pythium, Curvularia, and uncharacterized fungal endophytes. Both approaches confirmed that while the roots were predominantly colonized by Fusaria (members of the Nectriaceae family), the leaves were essentially colonized by Alternaria (members of the Pleosporaceae family). Overall, the findings of the present study constitute, to the authors’ knowledge, the first extensive report on the diversity of endophytic fungal flora associated with date palm trees (P. dactylifera).     

More Than Just a Student Voice: Facilitating Student Leadership Development Through the Library Student Liaison Program

This article explores how the library-student liaison program at Eastern Washington University (EWU) Libraries has evolved into an opportunity for students to develop leadership skills. Originally designed to foster better communication between the EWU Libraries and students enrolled at the university, we recognized that the process of achieving established goals for the program provided a vehicle for students' leadership-skill development. To facilitate the leadership process, librarians employed the Social Change Model. Designed specifically for college students, this model engages the student to develop individual capacities to strengthen group activities that foster positive changes in the community and society.     

企业竞争情报和反竞争情报整合性研究

反竞争情报研究作为竞争情报的另一面,应该受到情报学界、咨询界和企业界的密切关注。本文指出了企业竞争情报和反竞争情报整合的必要性,探索性地对企业竞争情报和反竞争情报的整合机制进行了研究。探讨了企业竞争情报和反竞争情报的关系、竞争情报和反竞争情报整合的原理及其目标,并提出了将二者有机整合的架构和具体整合方法。

基于内容的图像检索技术研究进展及其在数字图书馆中的应用

基于内容的图像检索技术是对图像的物理内容为加工对象的检索技术之一,主要实现方式包括基于颜色、纹理、形状、空间位置和语义等。其中基于颜色的图像检索发展最为成熟,而基于语义的检索则尚处于探讨、研究阶段。基于内容检索和基于文本检索在数字图书馆中可以融合共同提供检索服务。Google为这一尝试提供了在后控阶段的有效案例,而真正的实现两者的融合是在预处理阶段。两者结合在数字图书馆中的应用是可行的,相信能够提供更好的图像检索服务。
