Global dimension of weak smash product

INTRODUCTION In (Auslander, 1995), the author established the relationship of homological dimension between skew group algebra ΛG and Λ. Recall from Corollary 4.7 and Corollary 4.10 in (Auslander, 1995) that gl.dim(ΛG)=gl.dim(Λ) where ΛG is a skew group algebra with the order of G invertible in Λ. Recently, more and more mathematicians have studied homological dimension for Hopf algebra. Yang (2002) gave the relationship of homological dimension between smash product algebra A#H…

推动公共图书馆事业“中部崛起”

“十二五”以来,公共图书馆事业发展出现了“中部洼地”现象。主要表现是:资源占有与服务人口不相称;发展速度相对趋慢;均等化水平低;可比服务成本上升。实现公共图书馆事业发展“中部崛起”,主要应从以下几方面着力:国家宏观政策的调整;强化地方政府主体责任;加快县域公共图书馆总分馆体系建设;拓展和深化“图书馆+”与“互联网+”;完善评价标准的导向作用;抓住促进贫困地区公共文化服务体系建设的历史机遇。表5。参考文献4。

Access and Express: Professional Perspectives on Public Library Makerspaces and Intellectual Freedom

This study examines the roles of makerspaces and librarians in public libraries, as defined by nine librarians instituting makerspace services. It explores their understanding of creative spaces and library policy, specifically the foundational principles of intellectual freedom and access. Using constructivist discourse analysis tools, this study analyzes interview data to illuminate a concept of access grounded in expression, incorporating hands-on activities, tools, and social connections. This study has implications for practitioners and policymakers in reconsidering access as a positive liberty enabled by social contexts, and librarians’ enzymatic roles in facilitating those contexts.     

Reimaging Public Libraries as Learning Communities: What Library Stories Can Tell Us

This article describes a study conducted in York County, Pennsylvania, on its countywide library system framed within the context of the statewide “Reimaging Libraries” Get Storied initiative, developed and marketed by organizational story consultant, Michael Margolis. Understood as an essential aspect of culture re-imaging and change, narratives were collected from library personnel by undergraduate students at Pennsylvania State University-York as part of a service-learning initiative (directed by the first author). Working closely with the library district consultant (second author), we assess the success of the initiative and make some recommendations for culture reimaging through the practice of storytelling.     

Public Library Services for Veterans: Selected Brief Case Studies

Public libraries across the country design and deliver programs for military veterans and their families, often collaborating with other organizations and agencies. The examples were assembled from both general and specialized interviews with librarians, and literature and Internet searches, with summaries of programs assembled and written by multiple researchers. The specific limitations on the listing in this article are clearly outlined in the first section. Overall, however, the article provides a good introductory overview of what’s going on in veteran’s programs and services in America’s public libraries in over seventy libraries in forty states. We hope this list of what public libraries have organized or are doing will supply other public librarians with ideas on how to provide new services or enhance their existing ones.
