Academic libraries are flocking to online social networking sites in an effort to meet users where they are. Pinterest is the latest of these rapidly growing online social networking tools. The author of this article reports results from a survey on academic libraries’ presence on Pinterest. The survey found most academic library pinboards are in their infancy. Findings suggest that before establishing a presence on Pinterest, libraries should focus on planning institutional profiles and boards. Example institutions are highlighted, and tips are offered for setting up profiles and pinning, based on information from the survey. 相似文献

An analysis of the impact of stakeholder consultation during the conservation decision-making processes is presented. Defining and finding opportunities for stakeholder communication within conservation work is an ethical necessity when working with cultural heritage, but the limits and practice of this necessity are less clear. Case studies are used to explore which aspects of the conservation process stakeholders are most likely to be consulted about, and reviews the impact of their views. It asks whether conservators have a preference in which decisions they are prepared to share with stakeholders across three aspects of conservation: the initial appraisal, treatment and the display or storage. Where consultation relates to treatment, conservators are more likely to fall back on their own technical authority except when those consulted are regarded as fellow professionals. Other categories of stakeholder such as artists, originating communities, and religious groups were found to be more constructively consulted on the understanding of the object and on care related to display and storage. Conservators should be offered more explicit guidance on the ethics of consultation, the aspects of consultation that they should engage with and on the ethical ways to deal with conflict arising from consultation. 相似文献

Analysis of how cultural heritage institutions' (CHI) digital assets are being cited on Wikipedia can be beneficial to understanding user needs and interests as well as priorities for collection development and digitization. This case study details an analysis of Wikipedia links to online resources from Louisiana cultural heritage institutions in order to determine what types of cultural heritage resources users are citing on Wikipedia, what is the content of the Wikipedia articles with Louisiana CHI citations, and how this can influence the work of CHI. The results of the study include findings that digital library items and archival finding aids are the most cited sources from cultural heritage institutions on Wikipedia and are particularly popular for Louisiana-specific Wikipedia articles on society and the social sciences and culture and the arts. Some possible strategies for determining digitization and collection development priorities based on these findings are also detailed. 相似文献

首先,从整体格局来看,中国的体育新闻报道呈现出综合性日报弱、专业体育报纸强的特点,而在美国,恰恰相反。其次,中国报刊的体育新闻报道往往带有更强烈的感情色彩,而美国的体育新闻报道更注重客观性的要求。第三,美国报刊体育版面比较漂亮,但是文字并不华丽、生动。中国报刊追求文字的生动活泼,但同时也暴露出在遣词造句上的一些不足。中美两国的报刊体育新闻报道都面临着如何应对电视和互联网挑战的问题,而他们采取的对策惊人的相似:一是拓宽体育报道的深度和广度;二是走娱乐化的路线。 相似文献

This study examines collaboration dynamics with the goal to predict and recommend collaborations starting from the current topology. Author-, institution-, and country-level collaboration networks are constructed using a ten-year data set on library and information science publications. Different statistical approaches are applied to these collaboration networks. The study shows that, for the employed data set in particular, higher-level collaboration networks (i.e., country-level collaboration networks) tend to yield more accurate prediction outcomes than lower-level ones (i.e., institution- and author-level collaboration networks). Based on the recommended collaborations of the data set, this study finds that neighbor-information-based approaches are more clustered on a 2-D multidimensional scaling map than topology-based ones. Limitations of the applied approaches on sparse collaboration networks are also discussed. 相似文献

In the studies of general library use, women use libraries more than men. When use studies of particular subjects are done, women nearly always are more likely to use libraries for information on that subject than men. Yet there are few studies on women's information needs or use studies of traditional women's subjects. When women's subjects are written about in the library literature, the articles are nearly always on collection development, not on information needs. Information on women's subjects is primarily requested in public libraries and is not considered worthy of scholarly concern. Five specific categories of women's subjects: traditional women's subjects like needlework, practical information for the home, information related to a change in life like returning to school or to work, information on women's health issues, and information about parenting are reviewed. Current trends in commercial electronic information systems and telecommunications technology make the issue of information needs research and analysis urgent. 相似文献

This paper describes a method, using Genetic Programming, to automatically determine term weighting schemes for the vector
space model. Based on a set of queries and their human determined relevant documents, weighting schemes are evolved which
achieve a high average precision. In Information Retrieval (IR) systems, useful information for term weighting schemes is
available from the query, individual documents and the collection as a whole.
We evolve term weighting schemes in both local (within-document) and global (collection-wide) domains which interact with
each other correctly to achieve a high average precision. These weighting schemes are tested on well-known test collections
and are compared to the traditional tf-idf weighting scheme and to the BM25 weighting scheme using standard IR performance metrics.
Furthermore, we show that the global weighting schemes evolved on small collections also increase average precision on larger
TREC data. These global weighting schemes are shown to adhere to Luhn’s resolving power as both high and low frequency terms
are assigned low weights. However, the local weightings evolved on small collections do not perform as well on large collections.
We conclude that in order to evolve improved local (within-document) weighting schemes it is necessary to evolve these on
large collections. 相似文献

Salary comparisons are important for the profession. They provide information that administrators and others in positions of authority need to make salary decisions. Although there are annually published sources of information on entry level positions, information on middle to senior level or on specialized positions in small colleges and universities is less readily available. There is no single source for comparing these salaries. To make this task easier, the authors review and evaluate sources of comparative salary data in relation to selected criteria that are particularly useful to small college and university librarians. 相似文献

Since the invention of artificial light, people have been working, studying, and playing for longer hours than ever before. They are also sleeping less as a result. This article examines the impact of sleep deprivation on people generally, and specifically on college students. Students accrue a large sleep debt that impairs their ability to function adequately. Students suffering from sleep deprivation can be as impaired as if they are drunk. They suffer damage to their minds and bodies. Adequate sleep can repair this damage, but with the many demands on college students, they may be unlikely to be able to accomplish this. Studies have indicated that naps are beneficial in helping to reduce students' sleep debts. Universities are realizing the importance of naps, and university libraries may be ideal locations for napping stations. Several options of providing students with safe comfortable napping areas are discussed. 相似文献

Television programs' production value is highly regarded by professionals as a crucial dimension of program quality. This study examines the degree to which lay viewers, rather than professionals, are sensitive to television programs' production value as a distinct evaluative dimension, their ability to pass educated judgments on production value, and the impact of these judgments on their overall program appreciation and quality assessment. Based on a large-scale survey of television viewers in Israel, we find that production value makes up a distinct evaluative dimension, indicating that viewers are sensitive to production considerations. Production value assessments also explain television program appreciation and quality evaluations. On the other hand, there are indications that lay viewers are not very good at discerning gradations of production value among different programs and genres. These findings are discussed in the context of the conflicting interests among Israeli program makers and television channel franchisers to cut costs or to invest in the quality and production value of domestically produced programs. Based on the findings, a deliberative procedure is suggested which can accommodate these conflicting interests by combining lay viewers’ quality assessments with professionals’ more considered and informed judgments. 相似文献
