The essay presents criteria for a “good theory” and then reviews advances in small group communication research during the 1980s. The fact that comparatively few scholars are dedicated to such research is then related to the criteria for good theory in discussions of, first, metaphors and imagination; second, puzzles and problems; and third, real‐world significance and outcomes. A call is made for the kind of research that will result in better small group theory.  相似文献

Lee et al. (2015) – based on Uzzi et al. (2013) – and Wang et al. (2017) proposed scores based on cited references (cited journals) data which can be used to measure the novelty of papers (named as novelty scores U and W in this study). Although previous research has used novelty scores in various empirical analyses, no study has been published up to now – to the best of our knowledge – which quantitatively tested the convergent validity of novelty scores: do these scores measure what they propose to measure? Using novelty assessments by faculty members (FMs) at F1000Prime for comparison, we tested the convergent validity of the two novelty scores (U and W). FMs’ assessments do not only refer to the quality of biomedical papers, but also to their characteristics (by assigning certain tags to the papers): for example, are the presented findings or formulated hypotheses novel (tags “new findings” and “hypothesis”)? We used these and other tags to investigate the convergent validity of both novelty scores. Our study reveals different results for the novelty scores: the results for novelty score U are mostly in agreement with previously formulated expectations. We found, for instance, that for a standard deviation (one unit) increase in novelty score U, the expected number of assignments of the “new finding” tag increase by 7.47%. The results for novelty score W, however, do not reflect convergent validity with the FMs’ assessments: only the results for some tags are in agreement with the expectations. Thus, we propose – based on our results – the use of novelty score U for measuring novelty quantitatively, but question the use of novelty score W.  相似文献

Forty-one bibliographers described how the Internet has changed their work, and six library directors speculated about future change. Findings confirm that responding bibliographers collect Internet resources and make broad use of the Internet as a collection tool, while the directors see their libraries as well-positioned for an uncertain future.  相似文献

Framing has become one of the most popular areas of research for scholars in communication and a wide variety of other disciplines, such as psychology, behavioral economics, political science, and sociology. Particularly in the communication discipline, however, ambiguities surrounding how we conceptualize and therefore operationalize framing have begun to overlap with other media effects models to a point that is dysfunctional. This article provides an in-depth examination of framing and positions the theory in the context of recent evolutions in media effects research. We begin by arguing for changes in how communication scholars approach framing as a theoretical construct. We urge scholars to abandon the general term “framing” altogether and instead distinguish between different types of framing. We also propose that, as a field, we refocus attention on the concept's original theoretical foundations and, more important, the potential empirical contributions that the concept can make to our field and our understanding of media effects. Finally, we discuss framing as a bridge between paradigms as we shift from an era of mass communication to one of echo chambers, tailored information and microtargeting in the new media environment.  相似文献

The publication indicator of the Finnish research funding system is based on a manual ranking of scholarly publication channels. These ranks, which represent the evaluated quality of the channels, are continuously kept up to date and thoroughly reevaluated every four years by groups of nominated scholars belonging to different disciplinary panels. This expert-based decision-making process is informed by available citation-based metrics and other relevant metadata characterizing the publication channels. The purpose of this paper is to introduce various approaches that can explain the basis and evolution of the quality of publication channels, i.e., ranks. This is important for the academic community, whose research work is being governed using the system. Data-based models that, with sufficient accuracy, explain the level of or changes in ranks provide assistance to the panels in their multi-objective decision making, thus suggesting and supporting the need to use more cost-effective, automated ranking mechanisms. The analysis relies on novel advances in machine learning systems for classification and predictive analysis, with special emphasis on local and global feature importance techniques.  相似文献

The purpose of this study was to identify and test the influences that lead individuals to actively manage the meaning of a company Mission Statement. Communication about a company Mission Statement was hypothesized to be a function of an individual's information environment, level of work unit commitment, trust in management, and organizational role. The Management of Meaning Scale (MMS) was developed to assess specific meaning management behaviors. The MMS was cast as the chief dependent variable in a path analysis using LISREL. The general model was well supported. Implications for practices associated with Mission Statement implementation are discussed.  相似文献

For libraries, the shift from ownership of printed works to access of electronic works has required the negotiation and processing of license agreements. Many rights and restrictions covered in license agreements are in direct conflict with traditional library processes and procedures. These agreements are contracts, based on contract law, and as such often supersede standard library policy based on copyright law. A comparison of rights guaranteed by the copyright law and rights assigned by a selected set of license agreements identifies certain areas of user rights that must be identified and protected.  相似文献

Covering violence is an expected part of the daily job for many journalists in the United States; however, are college and university programs fully preparing students for what they may experience? This study surveyed accredited journalism schools in the United States. Of the 41 respondent schools, only one offered a course specifically aimed at teaching journalists how to protect themselves from psychological trauma and how best to interact with victims of trauma. Results show that although schools believe the topic of trauma is important and worth teaching to future journalists, the approach to the topic is mostly reactive and inconsistent. Implications for the future of journalism education are discussed.  相似文献

Trust is an overused concept in our contemporary world. This paper explores the complex relationship of trust, efficiency, accountability, transparency and responsibility and their relationship to recordkeeping in our globalizing culture. It focuses on the profound changes that have taken place in the meaning and practice of audit within neo-liberal societies and how the ??rituals of verification?? and the ??managerialism?? may pervert the resulting record. It challenges the unthinking use of much of the rhetoric surrounding these concepts by archivists to justify their existence. It reflects on why the archival voice often remains silent or at best goes unheard in much of the discussion about these questions that have profound consequences for democratic societies. It is easy to lay the blame at the door of a perceived breakdown of trust rather than to consider whether the root of the problem lies with archivists and records managers themselves. This paper draws on my experience in directing the Information Management and Preservation MSC programme at the University of Glasgow and wide and serendipitous reading, which has sometimes been brought to my notice by students.  相似文献

  • Post‐publication peer review (PPPR) has not achieved its promise and potential.
  • Few articles receive PPPR – even those in high‐profile journals.
  • PPPR is difficult to find and needs to be linked to the original article.
  • Academics require recognition if they are to contribute their time to PPPR.
  • Improving PPPR would improve the scholarly corpus.

以上海文广新闻传媒集团转制为标志的新一轮“制播分离”讨论渐起高潮。经过初期的感性评说和等待观望,实务界和理论界的相关讨论开始转入理性个案分析和总体层面权衡。在不争的事实面前,情感上的宣泄在减少,建设性的观点开始增多。也许这场讨论所带来的不仅是事件本身意义的澄清,更为以往偏重于阶段性、战役性的广电理论研究带来历史考量、持续关注的理性之风。  相似文献

Background

Systematic reviews risk producing biased conclusions if a comprehensive search to identify eligible studies is not undertaken, but little evidence exists to guide prioritisation of databases to search when resources are limited.

Objectives

A systematic review examining interventions for managing frozen shoulder (adhesive capsulitis) was used to investigate the performance of bibliographic databases in identifying the included studies, the smallest combination of databases required to retrieve all included studies, and the performance of the searches themselves.

Methods

We calculated the yield of included studies from each of 15 databases, and the recall and precision of each search strategy. We investigated differences between the presence of a record in a database and its retrieval.

Results

Thirty of 31 studies were present in at least one database. Yields of individual databases ranged from 0% to 90% (median 23%). Two combinations of databases identified all 30 studies: Cochrane Central Register of Controlled Trials (CENTRAL) and Science Citation Index (SCI); or CENTRAL, MEDLINE and PreMEDLINE.

Conclusions

In a systematic review of a range of interventions used to manage frozen shoulder, at least two databases and reference checking were required to retrieve all included studies, but searching for future reviews should not be restricted.  相似文献

Community archives have compelled shifts in dominant archival management practices to reflect community agency and values. To analyse these shifts, we ask: In what ways do community archives and their staff challenge traditional archival modes of practice? Do community archives work within or against dominant frameworks for institutional sustainability? Do community archives challenge or replicate dominant custody practices? Based on semi-structured interviews with 17 founders, staff and volunteers at 12 Southern California community archives, this research examines the diverse models of practice utilised by community archives practitioners that diverge from and challenge standard practices in the field. By addressing these questions, our research uncovers a variety of models of practice employed by communities in Southern California to autonomously create and sustain their archives.  相似文献
