ABSTRACT Embedded librarianship focuses on the user and brings the library and the librarian to the user, wherever they are—office, laboratory, home, or even on their mobile device. This article provides an overview of the various ways libraries and librarians are embedding themselves into research and learning environs. Several roles are highlighted, including course-integrated instruction librarians as members of research teams, librarians collaborating with faculty in scholarly communication activities and librarians as partners in multidisciplinary, global, and virtual collaborations. Definitions of key terms precede the overview and provide context; consideration of the human resources side of the equation follows. Reflections on organizational structure conclude the article. 相似文献

ABSTRACTThe 2017 Equifax data breach left 144.5 million users digitally vulnerable to identity theft and future hacks. The organization’s failure to provide ongoing communication and information regarding the attack, motivated users to form crisis communities within the Twitter platform. This study examines the discourses present within the platform as users discussed the data breach. Digital crisis communities provide researchers opportunities to study how public users respond and react to a digital threat, particularly one that impacts online security and privacy. Through a qualitative analysis of tweets from the 3 weeks after the breach was announced, three discourses emerged that represented user frustrations and reactions to the security violation. These include breaking news, anger and outrage, and blame attribution. The findings of this study are relevant for those studying crisis communication, the Twitter platform, and online communities. 相似文献

This research examined the ways in which academic librarians and users interact when using social media tools such as Twitter and Weibo as well as end-users' and librarians' perceptions of the types of interaction through social media. The study conducted an analysis of 1600 microblog posts sampled from twenty university library Weibo (Chinese Twitter) sites and twenty library Twitter sites in English-speaking countries. The results were compared using Chi-Square analysis. Results indicated that at present academic librarians in English-speaking countries use post information relevant to the library (news and events) and respond to information/research inquiries. And academic librarians in China are likely to use Weibo to communicate with users and to disseminate library news. Given the lack of previous research on how social media such as micro-blogging in general facilitates communication between librarians and library users in academic libraries between in English-speaking countries and China, this study provides valuable information concerning librarians' and end-users' interactions of information/knowledge sharing activities, which will enable libraries to be better positioned to promote user engagement through SNS usage. 相似文献

Summary This article focuses on some major contributions from learning theory that impact how adults learn. Following an overview of two major learning theories—behavioral and cognitive theories—the authors discuss four factors that affect learning. These are attention, perception, memory, and contiguity and practice. Other topics presented include prior knowledge effect and transfer of knowledge problems. The article closes with five recommendations for incorporating results from learning theory research into reference service and user instruction. 相似文献

ABSTRACTThis article discusses how RADAR, the institutional repository (IR) at the Glasgow School of Art (GSA), has been modified to house an Annual Research Planning (ARP) template. A case study on the implementation of this research planning tool will outline the role that a repository and its staff can play in supporting individuals, enhancing processes, and helping to reach strategic institutional goals in preparing for the next Research Excellence Framework (REF). The paper will also investigate how the extension of RADAR to incorporate Current Research Information System (CRIS) elements has led to increased user engagement and has successfully demonstrated a new use for the repository beyond its scholarly communication function. 相似文献

The interplay between Twitter and media organizations has been an increasing area of research. This article examines how talk radio stations have adopted Twitter at an institutional level, based on a comparative study of the official accounts of three prominent talk radio stations in Canada in 2010 and 2011. While talk radio is considered an interpersonal medium, our analysis shows the stations mainly use Twitter as a one-way medium to broadcast news updates, rather than to engage with audiences. Our findings suggest a divergence between institutional and individual social media practices, with official accounts as formal channels of communication. 相似文献

ABSTRACTThis study introduces and evaluates the robustness of different volumetric, sentiment, and social network approaches to predict the elections in three Asian countries – Malaysia, India, and Pakistan from Twitter posts. We find that predictive power of social media performs well for India and Pakistan but is not effective for Malaysia. Overall, we find that it is useful to consider the recency of Twitter posts while using it to predict a real outcome, such as an election result. Sentiment information mined using machine learning models was the most accurate predictor of election outcomes. Social network information is stable despite sudden surges in political discussions, for e.g. around elections-related news events. Methods combining sentiment and volume information, or sentiment and social network information, are effective at predicting smaller vote shares, for e.g. vote shares in the case of independent candidates and regional parties. We conclude with a detailed discussion on the caveats of social media analysis for predicting real-world outcomes and recommendations for future work. 相似文献

The widespread availability of analytical tools for Big Data offers enormous opportunities and challenges for communication researchers. In contrast to user-generated texts, digital trace data (evidence of online user activities such as hyperlinks and retweets) represent a new methodological frontier for the field. However, interpretive strategies remain scattered and ad hoc with few best practices to guide them. To help remedy this situation, this article reviews recent scholarship in both communication and social computing research that has incorporated three common types of trace data: hyperlinks, Twitter followers, and retweets. It finds that while researchers in both fields have interpreted each trace in a variety of ways, they have largely declined to explain the validity of their interpretations. 相似文献

ABSTRACTWe introduce what user analytics can do in the first half of the paper and then illustrate how to do user analytics in the second half. In the current context, user analytics refers to a set of diverse communication research methods on uses and effects of social media. User analytics has evolved from TV ratings research to online user research. The history illustrates what data sources, measures, and analyses can be used for what types of research questions under user analytics. We discuss the similarities of and differences between user analytics and other methods of computational communication research (e.g. content mining and online experiments), and compare the strengths and weaknesses of user analytics with traditional quantitative methods (e.g. survey). Finally, we present an application study of Chinese bloggers to demonstrate how to employ user analytics methods to study the production, consumption, and effects of user-generated content. 相似文献

This study explores science communication on Twitter by investigating a sample of tweets referring to academic papers in five different scientific fields. The specifications of science communicators on Twitter, the characteristics of those who initiate actions (by tweeting), the extent and quality of reactions (retweeting), individual and group interactions, and the distribution of tweets across types of engagement in the process of science communication (i.e., dissemination, consultation, and evaluation) were explored. A broad array of actors is involved in the communication of science on Twitter, with individual citizens and individual researchers playing an important role. In principle, this is promising for creating direct interaction, which can be difficult through more traditional mass media. The vast majority of communication activities regarding academic papers is undigested dissemination with almost no sign of debate, contestation, or collective reflection. Another general finding of this study is that bot accounts play a major role in the science communication landscape on Twitter. 相似文献

Abstract During the early stages of the COVID-19 pandemic, the College’s library, learning center, & archives and the office of institutional research & training (OIRT), along with all departments of our college, shifted to working from home (WFH) during the COVID-19 pandemic. As we continue to work from home, in this column we share with you a follow-up to our previous column, specifically what worked and didn’t work in regards to the techniques and tools we continue to use to manage our staff remotely with communication tools (Slack, Zoom Calls, FlipGrid) and a project management tool (Notion) during the early stages of the pandemic. We added a new technique to the mix since our last publication—an Action Dashboard in Notion, and describe how we built it, and our plans for next steps using Notion as a comprehensive project management tool moving forward. 相似文献

Low-use tangible print collections represent a long-standing problem for academic libraries. Expanding on the previous research aimed at leveraging machine learning (ML) toward predicting patterns of collection use, this study explores the potential for adaptive boosting (AdaBoost) as a foundation for developing actionable predictive models of print title use. This study deploys the AdaBoost algorithm, with random forests used as the base classifier, via the adabag package for R. Methodological considerations associated with dataset congruence, as well as sample-based modeling versus novel data modeling, are explored in relation to four AdaBoost models that are trained and tested. Results of this study show AdaBoost as a promising ML solution for predictive modeling of print collections, with the central model of interest able to accurately predict use in over 85% of cases. This research also explores peripheral questions of interest related to general considerations when evaluating ML models, as well as the compatibility of similar models trained with e-book versus print book usage data. 相似文献

Web search engines are increasingly deploying many features, combined using learning to rank techniques. However, various practical questions remain concerning the manner in which learning to rank should be deployed. For instance, a sample of documents with sufficient recall is used, such that re-ranking of the sample by the learned model brings the relevant documents to the top. However, the properties of the document sample such as when to stop ranking—i.e. its minimum effective size—remain unstudied. Similarly, effective listwise learning to rank techniques minimise a loss function corresponding to a standard information retrieval evaluation measure. However, the appropriate choice of how to calculate the loss function—i.e. the choice of the learning evaluation measure and the rank depth at which this measure should be calculated—are as yet unclear. In this paper, we address all of these issues by formulating various hypotheses and research questions, before performing exhaustive experiments using multiple learning to rank techniques and different types of information needs on the ClueWeb09 and LETOR corpora. Among many conclusions, we find, for instance, that the smallest effective sample for a given query set is dependent on the type of information need of the queries, the document representation used during sampling and the test evaluation measure. As the sample size is varied, the selected features markedly change—for instance, we find that the link analysis features are favoured for smaller document samples. Moreover, despite reflecting a more realistic user model, the recently proposed ERR measure is not as effective as the traditional NDCG as a learning loss function. Overall, our comprehensive experiments provide the first empirical derivation of best practices for learning to rank deployments. 相似文献

Abstract This paper examines the research that has been conducted to date on the topic of library support for distance learning programs and identifies some priorities for future research. The two main types of studies prevalent in the literature on this topic are surveys of libraries and user studies. Research findings from the United States, United Kingdom, Australia, and Canada provide a perspective on the knowledge base in this area and enable some generalizations to be made about service provision and user needs. The results of a recent survey of librarians indicate that the number one research priority in distance learning library services is collaboration with faculty to integrate library and electronic resources into Web-based distance learning courses. 相似文献

Abstract Researchers and practitioners concerned with STEM learning (science, technology, engineering, and mathematics) occurring outside the institutional boundaries of schools recognize the need for assessment approaches that accommodate the characteristics of informal learning. These approaches, to be viable, must align with the activities, goals, roles, and outcomes we find in informal settings. A plausible starting point is in making use of naturalistic assessments—people’s own on‐going, developing awareness of who can do what under which circumstances. People regularly and informally assess one another to shape and support learning activities, goals, and outcomes. This article seeks to make a case for developing a new research program for assessing learning outcomes by capitalizing on people’s everyday attunements, which are already in place, and by getting more value out of the cultural apparatus that exists for recognizing one another’s capabilities. 相似文献

ABSTRACT Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general. 相似文献

AbstractUsing a population of ABA-approved law schools, this study attempts to quantify their institutional repositories and the types of items collected. I conducted a content analysis of repositories containing faculty scholarship, journal archives, and other collections. I located these collections through searching the Web, checking commercial directories and an AALL directory, and directly searching law school Web sites. Approximately 66% of law schools maintain institutional repositories containing faculty scholarship, journal archives, and/or other documents. This article includes recent research about other academic repositories, reviewing their success factors and general difficulties in implementing institutional repositories. 相似文献
