Climbing the Electronic Capitol Hill

Abstract

The Information Revolution, particularly evidenced by the Internet, e-mail and online access to government documents, has significantly affected the way Congress conducts business. The author reflects on the changes that he has had to make during his seven years of teaching a course on Congressional Office Operations for the U.S. Department of Agriculture (USDA) Graduate School. Through personal experiences, interviews, and historical perspectives, he describes changes in information resources, constituent communications, and press operations on Capitol Hill and how these changes have affected course content. He also describes how the events of September 11, 2001, and the anthrax mail problem have forced consideration of an electronic Congress. Serials Review 2002; 28:287–294.     

区域电子信息产业竞争力评价研究

为了清晰认识中国区域电子信息产业竞争力现状和区域间存在的差距,找出影响区域电子信息产业竞争力的关键要素,提升产业发展水平。以全国2009—2012年统计数据为依据,通过构建区域电子信息产业竞争力评价模型,运用熵值法对全国29个省市的电子信息产业综合竞争力进行了实证分析。结果表明:各区域电子信息产业在创新能力、生产能力、市场实现能力等方面存在一定差距,各省份依据其综合竞争力指数可划分为竞争实力强弱不均的四类地区,各地区内部省份之间电子信息产业发展水平仍存在区域性差异。     

The Impact of Web-Scale Discovery on the Use of Electronic Resources

Abstract

In 2015, the University of California, Berkeley, launched EBSCO Discovery Service (EDS), a web-scale discovery tool, with a goal of improving visibility and usage of collections. This study applies linear regression analysis to usage data for ebooks, ejournals, and abstracts and indexing (A&I) databases before and after implementation of EDS in order to identify correlations between the discovery layer and usage of library electronic resources across platforms. Our findings diverge from conclusions drawn in the previous literature that indicates that resource use generally increases after a discovery tool is implemented. We examine data from a longer period of time than the previous literature had, looking for statistically significant changes in resource use. The discovery layer at UC Berkeley did not lead to equal increases across platforms, but rather to a complex array of increases and decreases in use according to a variety of factors.

Electronic Social Psychology

Abstract

Unfortunately, it is not possible to comment on how the social psychological community has responded to ESP and its somewhat novel features, because ESP has not yet obtained a large audience. Many social psychologist are interested, but most simply do not have the equipment needed to use ESP. Many have personal computers, but few have modems, and those who do have modes haves not used them much. Further, some have expressed resersvations about the cost of telecommunicating, claiming that traditional means of communication serve the purpose well enough. Cost is a very legitimate concern, as telecommunicating can be expensive, but it is also somewhat short-sighted. (It reminds one of the reaction of some London business men who resisted the telephone because there were plenty of messenger boys in the city.) Computers offer people the chance to communicate and share information in ways that have not been possible before--in ways that can be beneficial to the community of social psychologists. One cannot evaluate telecommunications (or anything) solely in terms of its costs; it should be judged on a cost-benefit bases. While the benefits are somewhat difficult to judge at present, members of the profession will undoubtedly realize them in time. Telecommunications will not only stand the test of cost-benefit evaluation, but pass it with flying colors.

电子货币的货币乘数效应：基于中国的实证分析

 摘　　要:本文选取我国1990—2004年电子货币的样本数据，以及电子货币与货币乘数相关的变量，建立计量经济模型，对电子货币与货币乘数的相关性进行了统计检验。实证结果表明，电子货币对货币乘数具有放大效应，增强了货币乘数的内生性，加大了中央银行控制货币供给的难度，从而降低了货币政策的有效性。

基于GMDH的商业银行电子银行业务发展影响因素研究

电子银行业务发展影响因素是国内外学者重点关注的问题之一,采用自组织数据挖掘方法,客观、自动地筛选商业银行电子银行发展的主要影响因素,寻求电子银行业务发展与其影响因素之间的非线性关系。研究结果表明,电子银行交易额增长率、产品规划、网络营销和电子商务发展是电子银行业务的主要影响因素。前一期的电子银行交易额增长率和产品规划对电子银行业务发展的影响较大。网络营销对电子银行业务影响的持续时间较长,其与产品规划的交互作用的影响较大。电子商务通过与前期电子银行业务增长率的交互作用对电子银行发展产生影响。     

Negotiating Accessibility for Electronic Resources

Abstract

Accessibility of library electronic resources is a must. Its importance derives from professional ethics of librarianship, rising total costs of acquisition, and mounting legal challenges to colleges and universities that fail to provide resources accessible to users with disabilities. Library staff are responsible for ensuring the accessibility of vendor-licensed eresources. This column reviews the accessibility clauses of nine model license agreements for electronic resources. It describes terms that should go into an optimal accessibility clause and creates a composite model clause. It also provides guidance for library staff seeking to negotiate stronger accessibility language into vendor license agreements. Finally, it addresses the impact of accommodation requests on the total cost of acquiring library eresources, concluding with a call to redouble efforts to advocate for greater accessibility and educate both vendors and library staff about its importance.
