Authors in different disciplines exhibit very different behaviours on the so‐called ‘green’ road to open access, i.e. self‐archiving. This study looks at the self‐archiving behaviour of authors publishing in leading journals in six social science disciplines. It tests the hypothesis that authors are self‐archiving according to the norms of their respective disciplines rather than following self‐archiving policies of publishers, and that, as a result, they are self‐archiving significant numbers of publisher PDF versions. It finds significant levels of self‐archiving, as well as significant self‐archiving of the publisher PDF version, in all the disciplines investigated. Publishers' self‐archiving policies have no influence on author self‐archiving practice. 相似文献

In a useful article regarding testing for moderator variables in meta‐analysis, Hall and Rosenthal (1991) suggest, among other things, that when the sample of studies is large enough, it is acceptable to use ordinary inferential statistics such as the analysis of variance to test for moderator variables. However, because meta‐analytic data points (effect sizes) differ in important ways from those for which ordinary inferential statistics were designed, we recommend that analysts use conventional meta‐analytic statistics, which are at least potentially more informative about the literature in question. Hall and Rosenthal also suggest that tests of effect size variability should play a minimal role in meta‐analytic model tests. We concur that these tests of homogeneity cannot alone test for moderator variables and that at least tests between mean effect sizes should be performed. However, consistent with Hedges and Olkin's (1985) meta‐analytic framework, we show how homogeneity tests provide additional and valuable information regarding how completely a moderator (or set of moderators) explains the variation of effect sizes. Therefore, these goodness‐of‐fit statistics may prove quite valuable, especially in meta‐analyses of highly variable study outcomes. We further recommend that in meta‐analyses for which study outcomes are already consistent, analysts should continue to perform model tests if they have theoretical expectations about moderators. We discuss these and other meta‐analytic model testing concerns. 相似文献

This research explores the performance of Asian S&T journals based on the outcomes of various citation indicators. Indexed by Journal Citation Reports – Science Citation Index Expanded (JCR‐SCIE), journals published in China, Japan, India, Singapore, South Korea, and Taiwan between the years 2008 and 2012 are collected and analysed using bibliometrics and statistics methods. Results showed that the mean impact factor (IF) value of the journals from all countries was less than 1.3 throughout the period. Only journals from China and Japan had a mean IF or 5‐year IF (5Y‐IF) value exceeding 1. The self‐cited rate of the journals from South Korea remained the highest among selected countries but showed a declining trend every year. The self‐cited rates among journals from all the six Asian countries did not considerably affect the journals’ IF values. The results revealed that the IF‐based ranking factor (IF‐RF) of Chinese and Japanese journals in various subject fields constantly improved from 2008 to 2012, but this improvement trend was not observed in journals from the other four countries. Overall, the journals from Japan and China demonstrated stronger impacts than those from the other countries. 相似文献

Predatory publishing has become a much‐discussed and highly visible phenomenon over the past few years. One widespread, but hardly tested, assumption is the idea that articles published in predatory journals deviate substantially from those published in traditional journals. In this paper, we address this assumption by utilizing corpus linguistic tools. We compare the ‘academic‐like’ nature of articles from two different journals in political science, one top‐ranking and one alleged predatory. Our findings indicate that there is significant linguistic variation between the two corpora along the dimensions that we test. The articles display notable differences in the types and usage of keywords in the two journals. We conclude that articles published in so‐called predatory journals do not conform to linguistic norms used in higher‐quality journals. These findings may demonstrate a lack of quality control in predatory journals but may also indicate a lack of awareness and use of such linguistic norms by their authors. We also suggest that there is a need for the education of authors in science writing as this may enable them to publish in higher‐ranked and quality‐assured outlets. 相似文献

This study bases on two theorized aspects of web interactivity, human‐to‐online‐media interaction, and human‐to‐human‐via‐online‐media interaction, aiming to explore how the concept of ‘interactivity’ was defined and realized by primary candidates' websites in Taiwan's 2000 presidential election. Measured by an Interactivity Index Scale developed in this study, the research findings indicate that candidates' websites performed better in offering human‐to‐online‐media interaction; however, the human‐to‐human interaction via online media was not realized as the primary objective of the online campaigns. Further analysis revealed that even in the perspectives of human‐to‐online media interaction, candidates tended to define web interactivity in terms of working towards their interest, not towards those of the voters. The implication of such findings is provided for future studies on online political communication. 相似文献

This study tested the hypotheses that shyness is under‐represented in television advertising and that among shy characters, women and children are over‐represented. Network commercials were content‐analyzed for their characterizations of inhibited behaviors. Results indicated that shyness was rarely exhibited and, within the shy portrayals, men and children were more likely to be depicted as shy. 相似文献

Background: Systematic review articles support the advance of science and translation of research evidence into healthcare practice. Inaccurate retrieval from medline could limit access to reviews. Objective: To determine the quality of indexing systematic reviews and meta‐analyses in medline . Methods: The Clinical Hedges Database, containing the results of a hand search of 161 journals, was used to test medline indexing terms for their ability to retrieve systematic reviews that met predefined methodologic criteria (labelled as ‘pass’ review articles) and reviews that reported a meta‐analysis. Results: The Clinical Hedges Database contained 49 028 articles; 753 were ‘pass’ review articles (552 with a meta‐analysis). In total 758 review articles (independent of whether they passed) reported a meta‐analysis. The search strategy that retrieved the highest number of ‘pass’ systematic reviews achieved a sensitivity of 97.1%. The publication type ‘meta analysis’ had a false positive rate of 5.6% (95% CI 3.9 to 7.6), and false negative rate of 0.31% (95% CI 0.26 to 0.36) for retrieving systematic reviews that reported a meta‐analysis. Conclusions: Inaccuracies in indexing systematic reviews and meta‐analyses in medline can be partly overcome by a 5‐term search strategy. Introducing a publication type for systematic reviews of the literature could improve retrieval performance. 相似文献

This study examined the views of advertising academics regarding the peer‐review process in English‐language advertising journals. Three issues were examined. First, how do advertising academics assess the peer‐review process in advertising journals on the following dimensions: fairness, anonymity (truly double‐blind), timeliness, and effectiveness in improving the quality of research? Second, how do they perceive the ethicality of review process behaviors? Third, what steps do they suggest for improving the quality or integrity of the peer‐review process? Data was collected through a survey of US‐based advertising academics. The findings reveal that advertising academics believe that, for the most part, advertising journals are succeeding at fairness, protecting anonymity, improving the research of submitters, and avoiding ethical infractions in the review process. However, advertising academics would like to see improvements in timeliness as well as in incentives and guidelines provided to participants in the peer‐review process. 相似文献

A laboratory study was conducted to determine the types of compliance‐gaining and compliance‐resisting strategies selected and subsequently judged for effectiveness by college students in a simulated casual drinking context. 96 participants in the study were assigned one of two conditions in the study: compliance‐gaining (attempting to induce drinking by the partner) and compliance‐resisting (resisting offers of alcohol). Results indicated that participants in both conditions utilized direct forms of social influence most often (simple offer, direct refusal). Resistance strategies were rated more effective than compliance strategies and compliance‐gaining strategies were differentially rated as effective. Heavy drinkers and moderate drinkers rated the effectiveness of compliance‐gaining strategies differently from non‐drinkers. Theoretical implications were advanced for the compliance‐gaining/resisting area, and practical implications were suggested for those interested in developing programs for campus alcohol awareness. 相似文献

Objectives: This study surveyed Web 2.0 application in three types of selected health or medical‐related organisations such as university medical libraries, hospitals and non‐profit medical‐related organisations. Methods: Thirty organisations participated in an online survey on the perceived purposes, benefits and difficulties in using Web 2.0. A phone interview was further conducted with eight organisations (26.7%) to collect information on the use of Web 2.0. Data were analysed using both quantitative and qualitative approaches. Results: Results showed that knowledge and information sharing and the provision of a better communication platform were rated as the main purposes of using Web 2.0. Time constraints and low staff engagement were the most highly rated difficulties. In addition, most participants found Web 2.0 to be beneficial to their organisations. Conclusions: Medical‐related organisations that adopted Web 2.0 technologies have found them useful, with benefits outweighing the difficulties in the long run. The implications of this study are discussed to help medical‐related organisations make decisions regarding the use of Web 2.0 technologies. 相似文献

As tinkering and making spaces proliferate in museums, many researchers, practitioners, funders, and policy‐makers seek to understand what constitutes learning‐through‐tinkering. To support discussion of tinkering‐based learning, the Exploratorium sought to articulate and refine a valid, evidence‐based definition of learning in its permanent on‐floor Tinkering Studio. We studied and made videos of fifty learners and their companions in one of three tinkering activities in the Tinkering Studio. A team of researchers and practitioners used the videos to refine frameworks for learning and facilitation (initially developed in a prior project), leading to the identification of four Dimensions of Learning and three broad Facilitation Moves. We created a Tinkering Library of Exemplars that categorizes over one hundred video clips according to these frameworks. The Library may help articulate important aspects of learning and facilitation, give voice to practitioners’ values in defining learning‐through‐tinkering, and lay a methodological foundation for gathering evidence for such learning. The Library is available for download. 相似文献

MCN‐L, an email listserv administered by the Museum Computer Network, is open to anyone interested in discussing information technology in museums and other cultural heritage organizations. To determine how MCN‐L meets the needs of museum information professionals, this study presents an analysis of more than 6,000 emails sent to the listserv over a seven‐year period (2004–2011). The results of this analysis indicate that MCN‐L adds value to the online community of museum information professionals by providing an online communication channel focused on professional outreach and expert support, backed up by specific examples drawn from personal experiences. MCN‐L's emphasis on personal expertise is a key characteristic that speaks to the listserv's lasting value to the museum community and has implications for researchers and practitioners as they consider the future of computer‐mediated communication for all museum professionals. 相似文献

During the mid‐1980s political pressure upon Chinese journalists decreased, financial pressure upon their newspapers increased and photojournalism gained importance. This study compares the content of photographs in three ‘official’ and three hybrid ‘official‐commercial’ Chinese newspapers. Photographs were found to be less important in ‘official’ newspapers. Subjects and values of concern to government and Party leaders appeared more frequently in ‘official‐commercial’ papers. This study also shows that in a period of political and economic reform, diversity exists in photographic news content and that photographs frequently serve public interests. 相似文献

A growing number of online journals and academic platforms are adopting light peer review or ‘publish then filter’ models of scholarly communication. These approaches have the advantage of enabling instant exchanges of knowledge between academics and are part of a wider search for alternatives to traditional peer review and certification processes in scholarly publishing. However, establishing credibility and identifying the correct balance between communication and scholarly rigour remains an important challenge for digital communication platforms targeting academic communities. This paper looks at a highly influential, government‐backed, open publishing platform in China: Science Paper Online, which is using transparent post‐publication peer‐review processes to encourage innovation and address systemic problems in China's traditional academic publishing system. There can be little doubt that the Chinese academic publishing landscape differs in important ways from counterparts in the United States and Western Europe. However, this article suggests that developments in China also provide important lessons about the potential of digital technology and government policy to facilitate a large‐scale shift towards more open and networked models of scholarly communication. 相似文献

The study of jealousy is typically restricted to the examination of a third‐party threat to one's romantic relationship. In contrast to this rather narrow view, two studies were undertaken to examine the possibility (a) that individuals experience jealousy over a variety of issues, and (b) that jealousy‐of any type—occurs and is expressed in non‐romantic relationships such as cross‐sex friendship. The goal of Study I was to assess the realism of hypothetical situations representing six different types of jealousy suggested within the literature. These included: friend jealousy, arising from an individual's relationships with friends; family jealousy, arising from a partner's relationships with family members; activity jealousy, occurring when a partner is involved in activities such as school, work, or hobbies; power jealousy, arising from influence over a partner being lost to others; intimacy jealousy, arising when one feels that more advice is sought from or disclosed to others; and romantic jealousy, involving a (perceived) third‐party threat to a relationship's exclusive nature. In Study II, participants were presented with the finalized versions of these jealousy‐evoking scenarios and asked to imagine their cross‐sex friends engaging in such behavior. Respondents then rated the degree of jealousy‐related emotions they would experience in response to each situation and reported how they would express such jealousy. Results indicated that individuals’ emotional reactions and response modes differed according to the type of jealousy encountered. In particular, participants reported the most intense reactions to intimacy jealousy and felt that it was best dealt with by direct modes of communication. Implications of these findings for the study of jealousy in close relationships are discussed. 相似文献

Five factors are shaping the STM publishing industry: the shift from a supply‐driven to a user‐driven industry; conversion of paper‐based products to an all electronic environment; commoditization of online publishing technology; consolidation; and saturation of the traditional buyer market. Opportunities exist for publishers who can leverage their traditional content assets into new products that help specifically defined user‐groups accelerate and enhance the value creation process in vertical industry sectors. Research conducted with one group of researchers within one group of functions in one given industry describes the results of such an approach. 相似文献

The paper examines the social impact of communication technology applying the insights of sociologists such as Durkheim, Mead and Shils. It argues that the introduction of modern communication technology to Third World societies has resulted in the sudden and rapid increase of ‘social density’ or social relationships by bringing to the consciousness of individuals issues and personalities outside their immediate experience. In some Third World societies this has resulted in the emergence of a heightened individual self‐identity in order to understand and give meaning to new and unfamiliar situations created by the media. The socio‐political consequences of this new self‐identity for the plural societies of Asia is examined using the media‐image of Mahatma Gandhi in pre‐independent India. 相似文献

Forbidden to censor, and saddled with an undefined (and perhaps undefinable) criterion of the “public interest, convenience and necessity”; for deciding among otherwise‐qualified applicants for a broadcast facility, it is little wonder that the FCC has relied upon a patchwork of precedents and rule‐of‐thumb standards. Possibly because of the uncertainty of these standards, and partly because the staff has not increased in size as greatly as has the workload, the Commission has avoided whenever possible the enlargement of license application hearings to include anyone other than the applicants themselves. Sometimes, however, the courts haven't allowed the FCC to so restrict the number of participants in a hearing, and sometimes the courts have had to remind the Commission that the laboriously accumulated body of administrative practice and precedent is not always the same as the language or purpose of the Communications Act of 1934. “Economic injury”; is a station owner's concept. It is at the interface of theory and marketplace reality. It is the almost impossible‐to‐prove claim that the establishment of a new station in one's market will so split the available revenues that both stations will fail—or, at least, that both stations will have to operate with substandard (e.g., cheaper) programming, and thus will not serve the public interest. At first, the FCC listened to some of these claims, but soon evolved a policy of avoiding them, by whatever means and reasoning that it could. Over the years, and despite substantial prodding from the courts, the FCC's policy of avoiding this claim has become rigid . . . thus providing us with an excellent and fascinating case study of administrative policy formulation. 相似文献

Abstract This study applied a resource‐based view (RBV) strategy framework to analyze the major broadcast television networks’ alliances with Internet firms in the United States from 1998 to 2001 in the context of the convergence between the Internet and television. The findings show that the television networks primarily contributed property‐based resources, while the Internet firms largely contributed knowledge‐based resources to the alliances. The findings also indicate that the broadcast networks’ alliance structural preferences were influenced by the resources they contributed to and what they desired to access through the alliances. The networks used their property‐based resources as a basis to form Internet alliances, and in return they obtained access to Internet firms’ knowledge‐based resources that are essential in creating an Internet presence for the broadcasters. 相似文献
