Academic medical libraries have a responsibility to inform library users regarding retracted publications. Many have created policies and procedures that identify flawed journal articles. A questionnaire was sent to the 129 academic medical libraries in the United States and Canada to find out how many had policies and procedures for identifying retracted publications. Of the returned questionnaires, 59% had no policy and no practice for calling the attention of the library user to retracted publications. Forty-one percent of the libraries called attention to retractions with or without a formal policy for doing so. Several responding libraries included their policy statement with the survey. The increasing number of academic medical libraries that realize the importance of having policies and practices in place highlights the necessity for this procedure.  相似文献

Participation in shared-reading experiences is associated with children's language and literacy outcomes, yet few standardized assessments of shared-reading quality exist. The purpose of this study was to describe the psychometric characteristics of the Systematic Assessment of Book Reading (SABR), an observational tool designed to characterize the quality of classroom-based shared-reading sessions in early childhood settings. Participants included 105 preschool teachers. The quality of teachers’ videotaped, whole-class shared-reading sessions was examined using the SABR. Reliability levels for each of the SABRs five constructs were examined, as well as delayed alternate-form reliability and inter-rater reliability. The tools’ factor structure and construct validity were also assessed. Findings provide initial validation and preliminary evidence that the SABR is a reliable and valid tool. Potential uses for early childhood researchers, teachers, and allied professionals are described.  相似文献

This study investigates the experience of teaching of 19 teachers who are teaching on university courses involving face-to-face and on-line learning. The teachers are asked about how they think about learning technologies and how they approach the design and teaching of their courses across these two contexts. Results show that there are qualitatively different ways of thinking about learning technologies that relate logically and positively to qualitatively different ways of designing and teaching using learning technologies. The results have implications for teachers and those interested in maximising the likelihood of learning for university students when teachers teach with learning technologies.  相似文献

Abstract

This article examines the ACPA/NASPA Competencies as functional protocol of the neoliberal state. Described as ‘not a checklist’, Competencies structure rubrics, conferences, jobs, and performance as static, indicative of a power/knowledge rooted in protocol. We utilize post qualitative thinking, specifically poetics, to create a series of experimentations (in)tension with Competencies. This micropolitical practice disrupts protocol, opening imaginative space for subversion, movement, and becoming?~?professional.  相似文献

Although prior studies investigating immigration news typically documented a dominant focus on negativity and threats, only limited empirical research is available, which scrutinizes the way real-world developments affect these patterns in immigration news. This study aims to fill this void. First, we report results of a large-scale and longitudinal content analysis (N = 4,340,757) of trends in immigration news coverage in two Western European cases, Flanders (the northern, Dutch-speaking, largest region of Belgium) and the Netherlands, from 1999 to 2015. Both the salience of immigration as a news topic on itself and its linkages with three prominent issues (i.e., crime, terrorism, and socioeconomic issues) are explored. Second, this study builds on previous insights by comparing dynamics in immigration news to real-world events and developments. Overall, the results show that the linkage of immigration to issues of crime, terrorism, and the economy in Flemish and Dutch newspapers was considerable throughout the 17-year period under study. Yet there is limited evidence for a close relationship between news and real-life developments; hence, trends in immigration news seem largely unaffected by trends in society.  相似文献

Background: Internet‐based applications, in particular those that allow communication, have great potential to meet information needs. Limited research has indicated that people with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS; PHAs) use these technologies, but it has not yet been examined how resources are used collaboratively and in conjunction with offline sources. Objectives: The purpose of this study was to determine in what ways PHAs collaborate to meet treatment information needs and what role Internet‐based computer‐mediated communication (CMC) played in meeting this goal. Methods: This exploratory study was implemented using surveys and focus groups with 23 participants in Toronto, Canada. The purposive sample included men and women. Results: A variety of both off‐ and online resources were used to learn about HIV/AIDS treatment information, including web‐based and print. All participants were communicating with others, primarily in person, and most desired anecdotal treatment information. However, few reported using CMC to accomplish this goal. Harris and Dewdney's Principles of Information Seeking was used to frame the findings. Conclusions: Despite technical proficiency with CMC, few participants in this study reported use of this communication tool. Information professionals need to ensure access to HIV health information including those in remote areas who have fewer resources.  相似文献

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months.  相似文献

The current research explored two new social movement networks in the United States in order to demonstrate the impact of narrative capacity on the “shape” of an activist network. In particular, we found that activists in a network that demonstrated efficient narrative capacity described the hub organization in positive terms, while activists in a network that demonstrated poor narrative capacity held mixed perceptions about the hub. Some activists in the second network held positive perceptions about the organization, while others held negative perceptions. The observations from these two research sites led us to conceptualize activists' differing perceptions about their respective hub organizations as “distance” that they experienced from that hub. Therefore, two different star shapes emerged from our research: a symmetrical star and elongated star. Such findings demonstrate the importance for narrative capacity in the construction and maintenance of effective activist networks.  相似文献

Eighteen new counselor educators shared in‐depth reports of their efforts to establish an early record of scholarly productivity, critical to their success in academe. Analyses of their experiences using consensual qualitative research methods revealed components of both highly positive and highly discouraging program environments and their impact on participants’ research goals.  相似文献
