Columbia University Libraries’ longtime Slavic & East European Studies Librarian Nina Len?ek passed away on November 25, 2014, at the age of 90. On January 22, 2015, a large group of her friends, family, and colleagues gathered at Butler Library to remember, honor, and celebrate her remarkable life and legacy.  相似文献

This paper presents results taken from 2008 to 2010 of an ongoing microform use study. The number of titles used is evenly distributed over time with microfilm being the most used format and newspapers accounting for half of all usage. When publications are available electronically, users may still use the microform version. This study illustrates how microform and electronic collections are complementary—electronic materials provide better access but microform is better for preservation. Users prefer electronic materials but will also use microform when there is no online version available or when the online version is not an exact copy of the original.  相似文献

ABSTRACT

The types of information required by hospital and clinical staff can be greatly influenced by the geography and culture of the area in which they operate. In some situations, information must be acquired from sources that fall outside the traditional provisions of a medical or reference library. This article provides examples of the unique information needs of clinical staff serving a primarily Native Alaskan and Native American clientele in Alaska. It also presents sources and personnel utilized to meet those information needs outside of traditional reference sources.  相似文献

Being able to probive live coverage of breaking news events is one of the unparalleled strengths of television. The purpose of this study is to assess the opinions of 18–24 year olds about live television news reporting. Variables identified by respondents are characterized in one of three ways: awareness of live reporting; positive aspects of live reporting; and negative aspects of live reporting. From the more than 500 young adults surveyed, findings show most do not base their viewing habits on how often a news operation goes live or whether that operation happens to be first to hit the air with breaking news.

Respondents show strong agreement that live reporting gives the story a sense of immediacy, leading the positive attributes of live reporting. However, leading the list of negative attributes is the criticism that there are times when a live report is meaningless. There were differences in resoonses based on the market in which the respondents reside.  相似文献

ABSTRACT

This paper proposes a new way of interpreting particulate matter deposition indoors. The rate of deposition of dust in surfaces is presented as the result of the combination of two main factors: the concentration of suspended particles close to surfaces, and their capacity to deposit, expressed as the deposition velocity. We suggest that either of these two factors can be altered in order to mitigate deposition. The implications of this perspective are explored using in-situ measurements in a historic property (Apsley House, London) and a computational fluid dynamics model of aerosol deposition. The cases studied involve the effect of outdoor wind on the ingress of particles, the consequences of leaving the main door open, and the effects of the ventilation system on deposition. The results demonstrate that simulations can be used reliably to explore hypothetical scenarios or situations that would be experimentally challenging. The inputs and outputs of the computational model are discussed in view of its usability in preventive conservation.  相似文献

This article explores the development and automation of quality assurance procedures for locally loading electronic books (ebooks) on the Ontario Council of University Libraries’ Scholars Portal Platform. The authors conducted a two-phase study of MARC record fields indexed on the platform to detect errors and implement workflow changes to the quality control process. The authors report on this process and the costs involved and suggest that the challenges of ebook metadata are not met by MARC and a new metadata standard should be considered in the near future.  相似文献

The researchers working on information society measures have recently started to consider how people use the Internet not only as a tool but also as a platform for social relations. As the ultimate objective of information society measures is to provide reliable guidelines for social policy, finding criteria for separating “positive” uses of Internet from “negative” ones is an important task. This article employs the concepts of communicative and strategic action as defined by Habermas for that purpose. A general conceptual typology of three communicative and three strategic social uses of Internet is offered, which can be applied to measure uses of any of the Internet's interactive services. A specific empirical application to social uses of personal web sites demonstrates that the deduced measurement instruments achieve satisfying levels of validity and reliability.  相似文献

This article discusses teachers' views of their own learning. Two groups of teachers attending graduate programmes in Seattle, Washington in the United States of America (USA) and Newcastle upon Tyne, United Kingdom (UK), participated in a project that encouraged them to discuss examples of effective professional development. The teachers from the UK were enrolled on a Masters degree course for staff working with pupils with autism. The teachers from the USA were enrolled on a Masters degree course specifically focused upon working with children who have moderate to severe difficulties. Both groups of teachers were working, at least for a portion of their timetables, with pupils who had low incidence disabilities. Phyllis Jones, of the University of South Florida, Elizabeth West, from the Department of Special Education at Boise State University, and Dana Stevens, who is working on her PhD in special education at the University of Washington, analysed the critical moments of professional development identified by the teachers in both contexts. Four themes emerged: seeing the relationship between theory and practice, the role of the professor or lecturer in mediating learning, learning from others and reflecting in action. In this article, the authors analyse the themes in relation to the subtle differences that occurred within, and across, the two contexts. This analysis will assist in the design of quality professional development opportunities that reflect teachers' voices. Teachers make meaning of their learning in highly personal ways and, although it is possible to nurture formalised learning opportunities, teacher educators need to be constantly aware of the contextual and personal meaning making that is at play.  相似文献
