In upcoming years, two major changes in the computing landscape will reshape how map and GIS data libraries (MGDLs) will be required to perform their core functions in the future. These advancements—cloud computing and the “Big Data era”—offer opportunities and challenges for libraries, but most dramatically changes. Commercial cloud computing solutions are available as on-demand service; low-cost, internal private clouds are now a financial possibility. Simultaneously, Geographic Information Science (GISci) data and services have advanced at an ever-increasing pace into the “Big Data,” swelling the types and amounts of GIS data and services available. These two shifts have and will impact the entire GIS world and MGDLs, in response, and will now be required to collect, curate, and make available more data and services than ever. The MGDL community must be prepared to respond and react in order to remain effective. This article explores the evolving landscapes within which MGDLs must operate and examines how their roles and operational organization will be impacted. The hope of the authors is that such analyses will spark community-driven discussion to motivate the next major phase of research and implementation in the world of MGDLs.  相似文献

Successful subject searching depends upon the terminology of the search query. This paper compares the terminology of book titles with that of Library of Congress Subject Headings (LCSH) 1 on a semantic level. Methods of ananlyzing titles into title phrases that serve as matching units are described. Guidelines used to choose LCSHs with the closest semantic matches to title phrases are set forth. The pairing of title phrases with semantically related LCSHs constitutes the data of the study. Categories representing the types of semantic relationships holding between pairs of terms are defined. Results of the study show that the most common semantic relationship holding between title phrases and LCSH is a hierarchical one where title phrases are more specific than LCSHs.  相似文献

This essay provides a metatheoretical framework for understanding the complexities surrounding African journalism in the era of interactive digital technologies. It argues for the continued relevance of traditional theoretical paradigms, and submits that radical calls to develop new theories as well as to de-Westernise contemporary journalism studies through exclusively deploying “home-grown” concepts such as ubuntuism are not necessarily always viable. Rather, there is more to gain from appropriating traditional theories and identifying possible synergies between the “old”, predominantly Western approaches, and the “new digital phenomena”, and weaving out of that dialogue, approaches that are not radically different but are in tune with the uniqueness of African experiences. This approach, as the study argues, is particularly important given that journalism (including its appropriation of new technologies) always takes on the form and colouring of the social structure in which it operates. The study thus draws on social constructivist approaches to technology and the sociology of journalism, as well as an array of theoretical concerns from African journalism scholarship to offer a possible direction for a conceptual framework that can help us to capture the complex imbrications between new digital technologies and journalism practice in Africa.  相似文献

Although academic libraries continue to use social media to encourage student use of libraries and promote library resources and services, there has not yet been a study of social media use by the academic libraries in Montréal. This paper examines the social media accounts of the four university libraries in Montréal and, based on data gathered over the course of an 8-month period, seeks to determine the influence of each libraries' social media activity. Success was defined by measurable growth in the number of followers during the period studied. For the three universities with Facebook and Twitter accounts, the account considered most successful was the one with the highest engagement rate. The results indicate that all of the libraries were successful on the first measure, and the libraries with the fewest number of posts had higher levels of user engagement.  相似文献

The library's mission is to support the information and educational needs of its users. E-journal “Big Deals” offer libraries one method of maximizing the resources available to their users, but, with libraries now experiencing flat or decreasing budgets, these Big Deals present budgetary difficulties for libraries. They also remove collection development decisions from the control of the libraries themselves. Some libraries have canceled their Big Deals, resulting in problems. This article presents the results of an online survey of libraries regarding these bundled journal packages.  相似文献

This article describes a half-day pre-conference focused on the ins and outs of assessing “Big Deals.” The presenters gave an overview of issues related to “Big Deals,” and engaged the attendees in discussions about their own experiences with the topic. They then detailed the process of assessing “Big Deals” at their institution, including their methods for evaluating usage statistics. Attendees were provided with sample Excel spreadsheets for hands-on exercises to practice applying the methods described.  相似文献

The advantages of bundling e-journals together into publisher collections include increased access to information for the subscribing institution's clients, purchasing cost-effectiveness, and streamlined workflows. Although cataloging a consortial e-journal collection has its advantages, there are also various pitfalls and the author outlines efforts by the CAUL (Council of Australian University Libraries) Consortium libraries to further streamline this process, working in conjunction with major publishers. Despite the advantages that publisher collections provide, pressures to unbundle existing packages continue to build, fueled by an ever-increasing selection of available electronic resources; decreases in, and competing demands on, library budgets; the impact of currency fluctuations; and poor usage for an alarmingly high proportion of collection titles. Consortial perspectives on bundling and unbundling titles are discussed, including options for managing the addition of new titles to the bundle and why customizing consortial collections currently does not work. Unbundling analyses carried out at Queensland University of Technology from 2006 to 2008, prior to the renewal of several major publisher collections, are presented as further case studies that illustrate why the “Big Deal” continues to persist.  相似文献

Early Canadian radio broadcasting policy privileged private, commercial broadcasting enterprises above alternative broadcasting formats, including amateur and community radio. One station, 10AB, operated by the Moose Jaw Radio Association (MJRA) and owned by community members took exception to this policy and engaged in a decade-long dispute with radio authorities, first the Radio Branch of the Department of Marine and Fisheries and later the Canadian Radio Broadcasting Commission (CRBC). The MJRA ignored regulations with which it disagreed and challenged the radio authorities whilst requesting a private commercial broadcasting license. Absorbed by perceived discrimination, the MJRA failed to understand the complex situation the CRBC faced. I argue that considering transnational radio history can deepen our understanding of the dispute between the local station and national regulators in Canada.  相似文献

The last two years have been times of turbulence for the BBC, and other broadcasters, in terms of their coverage of UK politics. Their reporting of the general elections of 2015 and 2017, of the 2016 European Union Referendum and the 2015 election of Jeremy Corbyn to the leadership of the Labour Party have been much criticised (as has that of other mainstream media outlets). And despite the rise of social media, the BBC remains the most used and most trusted source of news in the UK and hence is a vital element in the UK public sphere. Consequently, these journalistic failures—when its political coverage failed to reflect what turned out to be the reality on the ground - are particularly problematic. This brings into focus the issue of “the truth” in election and referendum campaigns. The example quoted here—about the Labour Party and antisemitism—illustrates the difficulties in arriving at the “truth”, even in the less frenetic atmosphere between campaigns. It demonstrates how there can be many truths and this, in itself, raises urgent questions about the nature of political journalism which pose challenges for public broadcasting in Britain with implications that go much wider.  相似文献
