University undergraduate students and library-related privacy issues

New technologies increase the ability to capture and retrieve data about library usage patterns and users. Collecting, analyzing, and using patron data, however, may raise concerns among library users about their online privacy and how the data collected might be used to their advantage or disadvantage. This article examines undergraduate students' knowledge and perceptions of online privacy issues, their opinions regarding who should collect and retain information about them, for what purposes, and under what circumstances.

Impact of New Library Technology on Training Paraprofessional Staff

This article discusses the training of para-professional library staff in new technologies with an emphasis on reference services. For the purposes of the article, paraprofessional is defined as those not holding the professional library science degree. General training principles and procedures are discussed including the training environment, equipment, handouts, and goals or projected outcomes. The results of a survey of training needs for Library and Information Studies graduate students working in the Northern Illinois University Libraries is incorporated into the article. This article concludes by suggesting that paraprofessional training is in effect a continuing education opportunity that focuses on skill development and learning transfer as a means to improve work performance.     

Superstars as Emotion-Eliciting Objects. An Examination of the Effect of the Emotion Mix of Movie Stars

This article examines how superstars can influence moviegoers' decision process via eliciting emotions. The article builds upon prior research in the role of emotions in consumption. The data of a survey study are used to capture the emotional profile of superstars. Results from a correspondence analysis indicate that superstars can be classified according to the basic emotions they elicit. The resulting “constellations” of superstars influence spectators' decisions. A nested logit model gives evidence that supports the importance of taking into account the difference among emotions of the same valence. Moreover, the emotional interdependence between superstars seems to influence spectators' willingness to attend a movie.     

Exposing multi-relational networks to single-relational network analysis algorithms

Many, if not most network analysis algorithms have been designed specifically for single-relational networks; that is, networks in which all edges are of the same type. For example, edges may either represent “friendship,” “kinship,” or “collaboration,” but not all of them together. In contrast, a multi-relational network is a network with a heterogeneous set of edge labels which can represent relationships of various types in a single data structure. While multi-relational networks are more expressive in terms of the variety of relationships they can capture, there is a need for a general framework for transferring the many single-relational network analysis algorithms to the multi-relational domain. It is not sufficient to execute a single-relational network analysis algorithm on a multi-relational network by simply ignoring edge labels. This article presents an algebra for mapping multi-relational networks to single-relational networks, thereby exposing them to single-relational network analysis algorithms.

Terra Populus: Workflows for Integrating and Harmonizing Geospatial Population and Environmental Data

The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population and environmental data. In this article, we describe our approaches to these challenges, with a particular focus on geospatial data workflows and associated provenance metadata. The goal of TerraPop is to enable research, learning, and policy analysis by providing integrated spatiotemporal data describing people and their environment. To do so, TerraPop is assembling a globe-spanning and temporally extensive collection of high-quality population and environmental data, ensuring good documentation, and developing a Web-based data access system that enables users to assemble customized integrated data sets drawing on a variety of data sources and formats. We describe TerraPop's collection strategies, detail the geospatial workflows involved in preparing data for ingest into the project database and those used to transform data across formats for dissemination, and discuss the system used to capture and manage provenance metadata throughout the project. A key aspect of the project is the development of global current and historical administrative unit boundaries that can be linked to census data. These boundaries serve as the linchpin of TerraPop's data integration strategy, and constitute an important data set in their own right.     

Making Room for a Learning Commons Space: Lessons in Weeding a Reference Collection Through Collaboration and Planning

This article describes the process designed to systematically weed two community college library reference collections in preparation for potential funding of a learning commons space. The author explains the methodology used to help facilitate the reassessment of nearly 10,000 reference titles by librarian liaisons. The goal of the project was to consistently capture each title’s weeding status designation along with required bibliographic data while stopping short of executing the weeding itself. Details about the process and consequences of the resulting category breakdowns are described in detail. The article lists key success factors such as working with teams from different departments to help manage the day-to-day procedures. Practical suggestions are offered about the use of collaborative tools, about methods for transmitting support data to liaison librarians to enable quick decisions, about goal setting, and about establishing consistent means of data collection.     

Third party digitisation at State Records New South Wales: a positive approach in a time of change

The need for all archives to move from the paper based to the digital world is very apparent. However, governments and funding entities are unwilling to invest in the back capture of archival materials. State Records NSW overcame this impasse by entering into commercial agreements with 3rd party providers of genealogical data. This article outlines some of the reasons for entering into such agreements and the positive outcomes for State Records NSW and users of digital archival material.     

Effects of Celebrity Media Exposure on Box-Office Performance

This article examines the relation between box-office performance and celebrity media exposure, as measured by appearances in the celebrity magazine, People. This study employs variables that capture different time periods to test whether People magazine appearances were merely part of a general promotional effort by a studio or whether appearances reflected the popular appeal of the actor. The results indicate that promotional appearances do not significantly affect box-office revenues. In fact, it is the star's popular appeal reflected in appearances prior to the promotional push that significantly affect box-office success.     

Student Journey Work: A Review of Academic Library Contributions to Student Transition and Success

This review aims to capture projects, services, and approaches that are being used to ensure student success and sustainability across the stages (or transitions) of the student experience of higher education, where these extend the traditional role of the library, in the UK and internationally. The article examines why the student journey (and supporting it) has become a central part of the contemporary academic library's repertoire. Fundamentally, through a student lifecycle perspective the author will attempt to show how academic libraries contribute to their university's bottom line? Finally, the article will reflect on strategic implications and areas for further investigation.

Does Commercialized Political Coverage Undermine Political Trust?: Evidence Across European Countries

Media commercialization has long been suspected of exerting a negative influence upon political culture. The news media's interest in intrigues, personal details, and scandals rather than political issues in order to capture audience attention is regarded by many as a prime source of political cynicism. This article scrutinizes this claim by examining whether a commercialized media environment correlates with lower levels of citizen political trust across countries. Integrating cross-national survey data with country-level measures of commercialized political coverage, the findings indicate that, across 33 European countries, a negative link exists between media commercialization and political trust. Replication of the analysis with a separate cross-national survey across 28 countries demonstrated the robustness of the findings. These support the claim that media commercialization undermines political trust.

Evaluating Multiple Intensively Collected Media Use Measures: Validity and Reliability of Momentary Assessments

Momentary assessment data collection methods can capture information about constructs that vary greatly throughout the day. The Measuring Youth Media Exposure methodology implemented multiple momentary measures of media use in addition to a time use diary (TUD), allowing evaluation of the convergent and divergent validity of these momentary assessment methodologies relative to the TUD. This article presents the reliability and validity of momentary questionnaires and momentary video recordings of media use in relation to conventional TUD using an adaptation of the multi–trait-multi-method matrix. Both momentary measures show good reliability as well as convergent and discriminant validity for assessing TV, video game, computer, and cell phone use in adolescents relative to the TUD.

Do altmetrics assess societal impact in a comparable way to case studies? An empirical test of the convergent validity of altmetrics based on data from the UK research excellence framework (REF)

Altmetrics have been proposed as a way to assess the societal impact of research. Although altmetrics are already in use as impact or attention metrics in different contexts, it is still not clear whether they really capture or reflect societal impact. This study is based on altmetrics, citation counts, research output and case study data from the UK Research Excellence Framework (REF), and peers’ REF assessments of research output and societal impact. We investigated the convergent validity of altmetrics by using two REF datasets: publications submitted as research output (PRO) to the REF and publications referenced in case studies (PCS). Case studies, which are intended to demonstrate societal impact, should cite the most relevant research papers. We used the MHq’ indicator for assessing impact – an indicator which has been introduced for count data with many zeros. The results of the first part of the analysis show that news media as well as mentions on Facebook, in blogs, in Wikipedia, and in policy-related documents have higher MHq’ values for PCS than for PRO. Thus, the altmetric indicators seem to have convergent validity for these data. In the second part of the analysis, altmetrics have been correlated with REF reviewers’ average scores on PCS. The negative or close to zero correlations question the convergent validity of altmetrics in that context. We suggest that they may capture a different aspect of societal impact (which can be called unknown attention) to that seen by reviewers (who are interested in the causal link between research and action in society).     

Experimental Linguistic Indexing for Information Retrieval

Abstract

The primary goal of the ELIXIR project was to achieve improvements in the performance of text-retrieval systems by confronting some of the challenges presented by the indexing of full-text documents. We explored two hypotheses involving the use of linguistic analysis to improve the automatic creation of indexes: (1) if it is possible to develop algorithms that index only the words which most closely capture the document's content-not the complete text, as is done in existing sys-tems-the retrieval of irrelevant documents might be minimized; (2) if it is possible to create indexing algorithms that perform a minimal syntactic parse required to capture important phrases, the index may represent the document's content even more accurately, increasing the likelihood that the article can be retrieved by a relevant query.
