Libraries deploying the LibQUAL+? survey can offer a lottery incentive and many do so in the hope of increasing response rates. Other libraries may be prohibited from offering one because of Institutional Review Board restrictions, as is the case at Oregon State University. We wanted to discover why libraries offer lottery incentives, what kinds of incentives, and if they believe these incentives have a positive impact on their response rates. The responding libraries hold a general belief that lottery incentives are effective, but base this on feeling rather than research. We examine what the literature says about lottery incentives and student populations. 相似文献

While researchers with retracted papers – publications that are withdrawn because of significant errors or scientific misconduct – carry a permanent stain on their publishing records, understanding the causes and initiators of such retractions can shed a different light on the matter. This paper, based on a random sample of 2,046 retracted papers, which were published between 1975 and 2019, extracted from Retraction Watch and the websites of major publishers, shows that 53% of the retraction notices do not specify who initiated the retraction. Nearly 10% of the retraction notes either omit or do not contain information related to reasons for retractions. Furthermore, most of the retracted papers in our sample have no limitation section; those who do are commonly unhelpful or irrelevant. The results carry three implications for scientific transparency: retraction notices need to be more informative; limitation sections ought to be a required and even an open section of all published articles; and finally, promoting ‘heroic acts’ in science can positively change the current publishing culture. 相似文献

The purpose of this research was to make comparisons between Finnish persons and persons from other populations, particularly those from the United States, on a variety of common measures of communication orientations. The results of the study indicated that differences between Finnish and United States samples do exist, but the differences are primarily restricted to willingness to communicate and introversion. Data relating to communication apprehension and self‐perceived communication competence for the two cultures are remarkably similar. However, these two variables appear to be much less predictive of willingness to communicate for Finns than they are for Americans. 相似文献

Traditional pooling-based information retrieval (IR) test collections typically have \(n= 50\)–100 topics, but it is difficult for an IR researcher to say why the topic set size should really be n. The present study provides details on principled ways to determine the number of topics for a test collection to be built, based on a specific set of statistical requirements. We employ Nagata’s three sample size design techniques, which are based on the paired t test, one-way ANOVA, and confidence intervals, respectively. These topic set size design methods require topic-by-run score matrices from past test collections for the purpose of estimating the within-system population variance for a particular evaluation measure. While the previous work of Sakai incorrectly used estimates of the total variances, here we use the correct estimates of the within-system variances, which yield slightly smaller topic set sizes than those reported previously by Sakai. Moreover, this study provides a comparison across the three methods. Our conclusions nevertheless echo those of Sakai: as different evaluation measures can have vastly different within-system variances, they require substantially different topic set sizes under the same set of statistical requirements; by analysing the tradeoff between the topic set size and the pool depth for a particular evaluation measure in advance, researchers can build statistically reliable yet highly economical test collections. 相似文献

The American baseball play Yogi Berra once observed that “The future ain’t what it used to be”. Berra's colourful expression states a fundamental truth: the future as we perceive it today is, more often than not, not how it was perceived in the past. The proof is in the chequered history of forecasting in every field from politics to technology. e-Government and e-democracy are no exceptions. In this article we examine the problem of inaccurate forecasting of the impact of ICT in the public sector. To do this, we use a typology of forecast failure and then use this typology to examine three case of inaccurate forecasts of the impact of e-government and e-democracy over the past 25 years and ask why these predictions were wrong. Drawing on the lessons from these examples and others, we propose a series of steps/actions that can help to reduce the probability of such errors occurring in the future. 相似文献

This study evaluated the sampling methods and sample populations used in all U.S.-based survey and experimental mass communication studies published between 2000 and 2014 in six major journals (N = 1,173). Most studies used nonprobability samples, and more than half used student samples. Experiments used more nonprobability and student samples than surveys. Funded studies used more probability and nonstudent samples than nonfunded studies. Implications of results pertaining to population validity and interpretations of findings for mass communication research are discussed. 相似文献

The scholarly communication landscape is rapidly changing and nowhere is this more evident than in the field of data management. Mandates by major funding agencies, further expanded by executive order and pending legislation in 2013, require many research grant applicants to provide data management plans for preserving and making their research data openly available. However, do faculty researchers have the requisite skill sets and are their institutions providing the necessary infrastructure to comply with these mandates? To answer these questions, three groups were surveyed in 2012: research and teaching faculty, sponsored programs office staff, and institutional repository librarians. Survey results indicate that while faculty desire to share their data, they often lack the skills to do this effectively. Similarly, while repository managers and sponsored programs offices often provide the necessary infrastructure and knowledge, these resources are not being promoted effectively to faculty. The study offers important insights about services academic libraries can provide to support faculty in their data management efforts: providing tools for sharing research data; assisting with describing, finding, or accessing research data; providing information on copyright and ownership issues associated with data sets; and assisting with writing data management plans. 相似文献

Research on information behavior, practice, and experience focuses on complex topics embedded in multiple circles of context. LIS researchers in these areas often adopt interpretive, participatory, or critical methods. Yet, they just as often are ambivalent to measurements of rigor, or they unintentionally use positivist criteria to measure quality. Each of these decisions is indicative of a deep-seated assumption about the nature of objectivity and subjectivity. Bricolage offers researchers a way to think about research outside of this assumption: to understand the object of inquiry as it really is, not as the researcher frames it. Thinking like a bricoleur, researchers circumvent exact research protocols and cultivate difference by combining methods, methodologies, theories, and philosophical positions in creative ways. Bricolage already has a toehold in LIS research, but the diverse topics and methods that researchers bring to studies of information behavior, practice, and experience call for greater engagement with it. 相似文献

Background: The relationship between health information seeking, patient engagement and health literacy is not well understood. This is especially true in medically underserved populations, which are often viewed as having limited access to health information. Objective: To improve communication between an urban health centre and the community it serves, a team of library and information science researchers undertook an assessment of patients’ level and methods of access to and use of the Internet. Methods: Data were collected in 53 face‐to‐face anonymous interviews with patients at the centre. Interviews were tape‐recorded for referential accuracy, and data were analysed to identify patterns of access and use. Results: Seventy‐two percentage of study participants reported having access to the Internet through either computers or cell phones. Barriers to Internet access were predominantly lack of equipment or training rather than lack of interest. Only 21% of those with Internet access reported using the Internet to look for health information. Conclusion: The findings suggest that lack of access to the Internet in itself is not the primary barrier to seeking health information in this population and that the digital divide exists not at the level of information access but rather at the level of information use. 相似文献

The new web-based academic communication platforms do not only enable researchers to better advertise their academic outputs, making them more visible than ever before, but they also provide a wide supply of metrics to help authors better understand the impact their work is making. This study has three objectives: a) to analyse the uptake of some of the most popular platforms (Google Scholar Citations, ResearcherID, ResearchGate, Mendeley and Twitter) by a specific scientific community (bibliometrics, scientometrics, informetrics, webometrics, and altmetrics); b) to compare the metrics available from each platform; and c) to determine the meaning of all these new metrics. To do this, the data available in these platforms about a sample of 811 authors (researchers in bibliometrics for whom a public profile Google Scholar Citations was found) were extracted. A total of 31 metrics were analysed. The results show that a high number of the analysed researchers only had a profile in Google Scholar Citations (159), or only in Google Scholar Citations and ResearchGate (142). Lastly, we find two kinds of metrics of online impact. First, metrics related to connectivity (followers), and second, all metrics associated to academic impact. This second group can further be divided into usage metrics (reads, views), and citation metrics. The results suggest that Google Scholar Citations is the source that provides more comprehensive citation-related data, whereas Twitter stands out in connectivity-related metrics. 相似文献

Summary In an effort to provide desktop access to information at Texas A&M University, an increasingly greater portion of the University Libraries' budget is being spent on electronic resources and services. This study, a survey of a random sample of the faculty and teaching staff, was designed to determine if these resources and services are being used by the targeted population and, if not, why. The results of the study indicate that a lack of information is the greatest obstacle to the use of electronic resources/services, and they suggest that the Libraries should place greater emphasis on outreach to the faculty and improved marketing strategies. 相似文献

Meta-analysis refers to the statistical methods used in research synthesis for combining and integrating results from individual studies. In this regard meta-analytical studies share with narrative reviews the goal of synthesizing the scientific literature on a particular topic, while as in the case of standard articles they present new results. This study aims to identify the potential similarities and differences between meta-analytical studies, reviews and standard articles as regards their impact and structural features in the field of psychology. To this end a random sample of 335 examples of each type of document were selected from the Thomson Reuters Web of Science database. The results showed that meta-analytical studies receive more citations than do both reviews and standard articles. All three types of documents showed a similar pattern in terms of institutional collaboration, while reviews and meta-analytical studies had a similar number of authors per document. However, reviews had a greater number of references and pages than did meta-analytical studies. The implications of these results for the scientific community are discussed. 相似文献

Joining up remains a high priority on the e-government agenda and requires extensive transformation. Stage models are predictable patterns which exist in the growth of organizations and unfold as discrete time periods that result in discontinuity and can help e-government development towards joined-up government. Although stage models may be conceptually appealing, these models are often not empirically validated, do not transcend the level of individual organizations, and provide little practical support to policymakers. Furthermore, they do not include the dynamic capabilities needed by organizations to transform from one stage to the next stage. 相似文献

This paper discusses what "automation of serials" should mean. It should include the all important check-in function, which is complicated for various reasons. Administrators don't usually know that a central serials file is dynamite. After watching computers we have come to realize how efficient a manual system can be and why. A truly automated system does not yet exist, but there are some semi-automated operations. Since computerization is here to stay, this paper sounds a number of warnings, among them the specter of information inflation and bibliographic overkill. Yet in the future automated serials systems will be effective if they are on-line and comprehensive, including full claiming and binding control, and ideally the ability to write checks. Reasons are given to explain why NOTIS-3 is probably the best system now in operation, although apparently not yet cost effective. This paper ends with a discussion of costs. Good cost studies do not appear to exist; yet a computerized serials system should not cost more than a manual one. 相似文献

E-books have yet to assume a significant place in academic library collections. This article focuses on extracting common themes from the literature that might help the reader better understand why e-books have not yet become the cornerstone of the academic library. Patrons do not use e-books because they find the experience of using e-books incongruous with their experience of using other electronic resources, and many of the unexpected limitations they encounter when using e-books are not inherent to the format. Most often, they are purposefully imposed limitations tied to digital rights management techniques. Librarians do not purchase e-books because the titles they want to acquire are often not available electronically, because they are priced or packaged in a way that makes them less appealing than their print counterparts, or because acquiring e-books does not easily integrate into their normal acquisitions workflow. 相似文献

Abstract Librarians frequently have the opportunity to purchase Russian publications from nontraditional retail outlets, such as authors, book agents, or other independent sources, rather than book vendors. These transactions take place for a number of reasons, but generally they are done to acquire specialized materials that are not readily available through established outlets. In addition, the domestic price of Russian books is substantially lower than the prices charged by foreign vendors and as a result independent Russian purchasing agents can offer books at very competitive prices. Unfortunately, because these transactions do not follow established library procedures, they are often very labor-intensive and difficult to complete. 相似文献

Social network analysis (SNA) as theoretical framework and quantitatively oriented methodology offers public libraries and public library researchers an as-yet-unexplored way into their big data stories based on these library connections with their community. SNA offers library and information science researchers a methodology, and suggests a new research agenda, to better envision the relationships public libraries have with their communities both in-person and online by exploring the kinds of ties they have, how these ties lead to relationships, and how these relationships can be characterized. The quantitative orientation of SNA combined with its methods of data analysis in the forms of networks and hubs could give libraries the “hard” data they are so often in need of to demonstrate their value to their political leaders, and could uncover new directions in library use and library relationships. 相似文献
