Narratives are one of the most powerful teaching tools available and are often regarded as central to the learning process. We investigate the role of narrative in adult learning in library instructional contexts, introducing the concepts of micro- and macro-narratives and illustrating these ideas using relevant teaching examples. Macro-narratives are stories that are common across many cultures and contain universal themes and lessons. Micro-narratives are stories that are uniquely relevant to the members of a particular group. We argue that both types can be used to create meaningful library learning experiences. 相似文献

Governments and citizens alike are reaching maturity levels in their Internet adoption. With citizens using online channels for more and more purposes, governments around the world are moving to a ‘digital by default’ service delivery strategy. The question arises as to whether online channels are indeed suited for all purposes and are the “go-to” channels when citizens need information in a variety of situations. In this study, we compare data collected in 2008 and 2017 in the Netherlands to assess the evolution in channel behavior. The analysis suggests that channel preferences and general usage are indeed shifting towards online channels, whilst gaps in online usage between age groups are narrowing. However, the findings also show that this shift is not uniform across all tasks. For certain purposes, choices for traditional channels remain surprisingly resilient. The findings suggest that while online channels are maturing, they are still not ready to replace other existing channels for all types of services. Our findings call for continued attention to integrated channel strategies that incorporate the strengths of individual service channels. 相似文献

This study reviews the literature on the evaluation of bibliographic instruction in academic libraries from 1980 to 1993. Four main issues are discussed: (1) the reasons why librarians are evaluating, (2) to what degree they are evaluating, (3) what specific aspects they are evaluating, and (4) which methodologies are being used. Results indicate that, despite a growing interest in the evaluation of bibliographic instruction, the same pattern of limited systematic evaluation identified in 1980 continues to exist. Barriers to the successful implementation of evaluation, as well as possible directions for the future, are also presented. 相似文献

Broadly, the task of this paper is to examine the connectionbetween social and individual opinion. More specifically, doesconsensus information, as manifested in the relative attractivenessof candidate appearances, affect candidate evaluations? If so,are differences significant, and are all individuals equallyaffected? By employing an experimental design and incorporatingthe personality construct of self-monitoring, I find that significantdifferences do in fact appear. These differences result fromthe relative weight individuals assign to social sources ofinformation in decision processes. High self-monitors are foundto be quite sensitive to consensus information (attractive ounattractive appearances) whereas low self-monitors are lessso. By conceiving physical appearances as consensus information,a unique understanding of the bond linking individual to collectiveopinion emerges. The great majority of mankind are satisfiedwith appearances, as though they were realities, and are oftenmore influenced by the things that seem than by those that are. 相似文献

Veterans are a unique population that can be found in libraries across the United States. Libraries of all types are developing new approaches to the veterans in their patron populations in the wake of the wars in Iraq and Afghanistan. This study identifies several common strategies that libraries, especially public and academic libraries, are employing to support their patrons who are veterans, as well as distinctions in strategy according to library type. It further explores whether libraries are relying upon library staff who are veterans when developing services and programming for patrons who are veterans. 相似文献

In a changing technological ecosystem where photojournalists are attempting to reach larger audiences, they are forced to serve multiple masters and social media platforms. The tools and terminologies that these visual storytellers and communicators are using are also changing, which forces many of them to grapple with their roles and how best to contribute their craft within a market that is drastically different than two decades ago. This study asked 104 photojournalism practitioners, academicians, and administrators to define and explain the term “Really Social Photojournalism” and if it might rise past the level of jargon in a changing vocation? The findings reveal there are many complexities with this new term. But there are also opportunities for RSP to evolve in the photojournalism ecosystems with the appropriate support of its various stakeholders. 相似文献

Despite the benefits of using online social support groups, prior research does not provide a solid understanding of the online factors related to an individual’s supportive interaction. Accordingly, this study aims to explore how various aspects of anonymity predict different levels of social support engagement. The current study uncovers that visually identifiable group members are more likely to get supportive responses than are visually anonymous members. Also, when support group members are visually and discursively identifiable, they are more likely to get supportive messages than those who are visually and discursively anonymous. Additionally, the more identifiable support group members are, the more they receive positive messages. Practical implications for the role of social support group members’ anonymity/identifiability on the overall social support process are presented. 相似文献

The National League for Nursing and the American Nurses' Association publish many works that are vital to nursing literature, but their publications are difficult for libraries to handle efficiently and for users to find. This paper discusses the problems involved in making NLNIANA publications accessible to users. A survey was conducted to determine how libraries are handling these publications and whether or not they are satisfied with their methods. Results show that a majority are content with their processing of NLNIANA materials and that these libraries are not using different methods to handle these publications from those who are not satisfied. 相似文献

Abstract The climate of change in music reference represents a challenge to librarians. The three issues in the library literature that probably have the greatest impact on music reference service and are the subject of this paper are changes in users, sources, and modes of access to sources. These three issues are certainly related, as users need to use sources, and they need to know how to access them in order to use them. Reference librarians are called upon to mediate this process. Music library collections have their own peculiarities, however. Because they contain a wider variety of materials than many other kinds of library collections, reference librarians for music collections must be aware of the format, content, and intended uses of these materials, as well as the research patterns of their patrons. In the recent past, as cultural norms have changed with the paradigm of Western culture, users have wanted to use music libraries in new ways, and librarians are challenged to accommodate them. The musical genres used and requested by today's library patrons are different than they once were, both for listening and for academic study. Musical reference sources are being issued in electronic formats, and this represents a challenge for some users. The expanded use of interlibrary loan and electronic access to materials represents new opportunities and challenges. Music librarians are being called upon to provide services to patrons they may never see. 相似文献

Although a substantial majority of academic libraries now provide streaming video, the literature contains few studies which focus on how such resources are used. This article presents the results of a qualitative research study consisting of in-depth interviews with 18 instructors who use of one category of streaming video resources, educational videos, which are important because they are sold a higher price than most individuals can afford, and thus are typically only available to instructors through the library. The study's main findings are that instructors think educational streaming video resources compare favorably to commercial and non-streaming alternatives in most respects and use them whenever possible, that the primary benefit of these resources is to facilitate better use of limited class time by enabling instructors to assign videos as outside-of-class viewing, and that the library is not the primary means instructors use to discover new educational streaming video resources. Additional insights are provided into factors that academic libraries should consider when deciding which resources to invest in, which acquisition models to pursue, and what marketing strategies to employ to ensure maximum usage. 相似文献

Customer expectations from a journal publisher can be affected by the size of the publishing firm. The economies of scale, efficiencies, branding, and value added services are explored in relationship to expectations of the author customer, the reading customer, and the paying customer. When the imperative to sell is removed, there are differences in quality perception for traditional commercial publishers versus open access mega journals. Regardless of the size of the publisher, those involved in the publishing world are committed to ensuring research results are shared and accessible to their readers. 相似文献

This study presents an analysis of Twitter networks from academic libraries housed in medium-sized, primarily undergraduate universities. Previous investigations on this topic have used networks of followers, i.e. attention, to show that accounts associated with a library's home institution are the prime influencers in library Twitter networks. That is, they are in key positions to disseminate library-related information. The library itself was found to be positioned to contribute to the institution-wide conversation as well. Networks of followers, however, are susceptible to unwanted influence from inactive users. The present study utilizes networks constructed from tweeting behavior to identify influencers. These networks are, thus, insensitive to inactive followers. The results are compared to those of the previously published follower networks. The behavior networks are significantly smaller and contain far fewer interactions than the follower networks; however, institutional accounts are found to be the principal influencers in these networks as well. Additionally, the social network analysis allows for the quantification of relationship strengths. The closest relationships are between library/institutional and library/student accounts. The former demonstrates that the libraries are active participants in the university-wide exchanges on Twitter and the institutional accounts often include the libraries in their messages. 相似文献

ABSTRACTLibraries are considered safe spaces to explore different topics facilitating the sharing of knowledge so it would appear that colle giality and civility are cornerstones of our service. But within our organizations, collegiality is not always stressed as an important value within the workplace. Civility and collegiality are important for libraries as they are the foundation of our public services and support diversity of ideas and open communication within the workplace. Collegiality standards are set by the leaders and managers within an organization and this column will explore the need for civility standards to successfully achieve library goals.Column Editor’s NoteLeadership skills are essential to creating libraries that are effective and relevant to their communities. While some individuals seem to possess inherent leadership capabilities, it is possible to develop and strengthen skills to effectively lead a department, unit, or organization. This column explores ways for librarians and library workers to improve their knowledge and abilities as they lead their units, libraries, communities, and the library profession. Interested authors are invited to submit articles for this column to the editor at maggie4@clemson.edu. 相似文献
