Consortial Ebook Archiving Environmental Scan

Academic libraries and consortia are spending the vast majority of their material budgets on digital content, including ebooks. A review of ebook preservation activities for the North American library consortia is provided along with a look at the major preservation services such as Portico, CLOCKSS and HathiTrust. Publishers and ebook aggregators are also examined to provide a broad environmental scan of the current ebook preservation activities and risks.

数字人文:作为学术资料再分配的新形式

本文试图从学术资料的“私密型—共享型”消费角度来理解数字人文对学术资料的再分配形式.研究认为:首先,数字人文发展对于传统人文学术内在矛盾的回应,试图在不牺牲学术资料的“固有产权”的背景下以技术手段修正学术资料使用的负外部性.其次,数字人文是学者与学者之间、学者与学界之间、学术与技术之间的联合与集聚,以及理性算计与价值扩...     

Press Credentials and Hybrid Boundary Zones: The Case of WorldNetDaily and the Standing Committee of Correspondents

ABSTRACT

Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed.     

谈高等职业教育的教材开发

教材已成为当前高职教育的薄弱环节。现有教材缺乏特色,内容陈旧,更新速度慢,相互衔接较差,不够重视实践性教学环节,高职急需开发一批高质量的特色教材。除了出版社及相关协会、学会外,高职院校也应承担起教材的编写工作,搞好“校本教材开发”工作,注重综合课教材、实践课教材、学院教育教学需要的特殊教材,以及校本电子教材的开发。     

浅圆仓侧压力分析

Rankine理论和Coulomb理论均不适合用于浅圆仓的侧压力计算. 基于此, 本文研究了浅圆仓散料侧压力的实际分布规律及计算方法. 根据极限平衡理论, 首先得到散粒体作用在单位周长的仓壁上的合压力, 然后通过严格的数学推导, 得到浅圆仓侧压力的分布规律. 结果表明, 本文结果与实仓试验结果相符, 说明本文公式不论对平堆还是锥堆都比较适合, 而Rankine理论和Coulomb理论用于浅圆仓均有缺陷.     

Enhancing Teaching and Learning: Libraries and Open Educational Resources in the Classroom

Academic libraries continually adjust services to adapt to the ever-changing landscape in higher education. In response to the broken textbook market, libraries are becoming actively involved in the open educational resources (OER) movement. Although there is not a formal program in place, librarians at Utah State University explored a collaborative approach to integrate OER in faculty members' courses. One goal of the effort was to work closely with faculty to consider course objectives and learning outcomes when evaluating and incorporating OER. This article identifies a streamlined process for targeting courses most suited for OER adoption and outlines a process of collaborating with teaching faculty to integrate relevant OER. The paper includes a detailed workflow that other libraries can easily adapt to make OER part of their faculty outreach toolkit.

Design considerations for series hybrid active power filter

Some important factors for designing a series hybrid active power filter (SHAPF) are presented in this paper for the case when the load is varied in a wide range and/or the source voltage is seriously distorted. Special design of passive filters, adaptive control of parameter and multi variant control are discussed in detail. The filter is stable, has good performance, and causes small capacitive reactive current. The simulation and experimental results accorded with the theoretical analysis results.
