University Libraries are Changing to Encourage More Student Use

Dramatic decrease of users in reference services is a trend observed all around the world. Rather than talking with students face to face at the library, we librarians provide virtual reference with email and instant message. On the other hand, there are increasing numbers of students who use libraries as their study rooms, to write papers, and to hold group meetings. The University Library System (ULS) of the University of Pittsburgh is undergoing a change so that students can make more use of information services, libraries’ most important function. This paper discus about ULS’s effort to meet users’ need and explore new role in the digital age, including introducing PittCat+ as a new online catalog like Google, in class instructions with LibGuides, D-Scribe Digital Publishing as an e-journal publisher, D-Scholarship as university repository, etc

Master formula approach to broken chiral U(3)xU(3) symmetry

The master formula approach to chiral symmetry breaking proposed by Yamagishi and Zahed is extended to the U_R(3)xU_L(3) group, in which effects of the U_A(1) anomaly and the flavor symmetry breaking m_u \not= m_d \not= m_s are properly contained. New identities for the gluon topological susceptibility and pi^0, eta, eta' -> gamma^(*) gamma^(*) decays are derived, which exactly embody the consequence from broken chiral symmetry in QCD without relying on any unphysical limit.Comment: Version to appear in PRD, 25 page

米国大学図書館におけるGIS サービスの動向 －過去のアンケート調査の比較とピッツバーグ大学図書館の現状から [Trend of GIS services in US Academic Libraries –from comparison of past surveys and current situation of the University of Pittsburgh]

本稿は，米国大学図書館が1990 年代前半から提供し始めたGIS（Geographic Information Systems）サービスの動向と将来の展望を，過去のアンケート調査と著者の追跡調査，GIS 教育との関わりを通して考察する。大規模大学図書館ではすでに90％の普及率に達しているが，今後利用者を増やしていくには，しっかりしたデータ・コレクション・プランが必要であると考えられる。また，中規模，小規模大学図書館はまだ20～30％の普及率でこれからも伸びるであろうが，より充実したGIS サービスを提供していくには，学科や学部との共同作業が望ましいと思われる。 [This paper studies trends and the prospects for future of GIS (Geographic Information Systems) services in U.S. academic libraries, which have started in early 1990s, based on past surveys, my follow-up survey, and relation with GIS education. Libraries at the doctoral/research universities offer GIS services almost 90% already, but they need to have a good data collection plan in order to increase users. Libraries at the master’s colleges and universities, and the baccalaureate colleges offer GIS services only 20-30% but its proportion will be increased in near future. They would better to do joint efforts between libraries and other departments on campus regarding the use of GIS for better services.

Core-tube morphology of multiwall carbon nanotubes

The present paper investigates the cross-sectional morphology of Multiwalled Carbon Nanotubes (MWNTs) restrained radially and circumferentially by an infinite surrounding elastic medium, subjected to uniform external hydrostatic pressure. In this study, a two-dimensional plane strain model is developed, assuming no variation of load and deformation along the tube axis. We find some characteristic cross-sectional shapes from the elastic buckling analysis. The effect of the surrounded elastic medium on the cross-sectional shape which occurs due to pressure buckling is focused on by the comparison with the shape for no elastic medium case in our discussion. It is suggested that in no embedded elastic medium cases, the cross-sectional shapes of inner tubes maintain circle or oval; on the other hand, an embedded medium may cause inner tube corrugation modes especially when the number of shells for MWNTs is small.Comment: 7 figures, 2 figure
