Scientific research is increasingly relying on collaborations to address complex real-world problems. Many researchers, policymakers, and administrators consider a multidisciplinary environment an important factor for fostering research collaborations, especially interdisciplinary ones that involve researchers from different disciplines. However, it remains unknown whether a higher level of multidisciplinarity within an academic institution is associated with internal collaborations that are more prevalent and more interdisciplinary. Analyzing 90,000 publications by 2500 faculty members in over 100 academic institutions from three multidisciplinary areas, information, public policy, and neuroscience, we investigated the connection between multidisciplinarity and research collaborations. Based on social network analysis and text mining, our analysis suggests that more multidisciplinary institutions are not necessarily more collaborative, although they do feature collaborations that are more interdisciplinary. Our findings provide implications for academic administrators and policymakers to promote research collaborations and interdisciplinarity in academic institutions. 相似文献

One of the critical issues in bibliometric research assessments is the time required to achieve maturity in citations. Citation counts can be considered a reliable proxy of the real impact of a work only if they are observed after sufficient time has passed from publication date. In the present work the authors investigate the effect of varying the time of citation observation on accuracy of productivity rankings for research institutions. Research productivity measures are calculated for all Italian universities active in the hard sciences in the 2001–2003 period, by individual field and discipline, with the time of the citation observation varying from 2004 to 2008. The objective is to support policy-makers in choosing a citation window that optimizes the tradeoff between accuracy of rankings and timeliness of the exercise. 相似文献

Basic research is the main powerhouse of a country’s potential for continuous economic growth, and national-level scientific research funding is an important source of capital that supports this basic research. Given these observations, this paper takes micro-level data from projects funded by the Department of Management Sciences in the National Natural Science Foundation of China between 2006 and 2010 to examine the relationship between the efficient use of research funding and the level of concentrated funding in certain research institutions. In contrast to the positive externalities produced by the concentration of R&D activities, our study finds that the accumulation of scientific research funding at the institution level is negative correlated with the knowledge output of the principal investigators of projects within the research institution. We explore the sources of the negative correlation and discuss some policy implications. 相似文献

Performance measurement and communicating about it with the broader public is not self-evident if one looks at public services organizations (Hernon, P., 1998. The government performance and results act. Government Information Quarterly, 15: 153–156). In Belgium and the Netherlands, one organization that has been under constant surveillance from its stakeholders is the railroad company. Originally a national public service, it has changed through a European directive to operate in a liberalized transportation market. In this paper, we present the results of a qualitative study into what the Belgian and Dutch railway companies measure about their performance towards travelers, how they measure it, and specifically how they communicate it to their employees and stakeholders. Although we might expect the Dutch railway company (NS) to be more transparent than the Belgian railway company (NMBS/SNCB), in reality the two organizations do not differ that much from each other. 相似文献

This experiment was designed to test the hypothesis that an individual's preference for and valuation of relatively unavailable communicative messages compared to more readily available messages is a function of and will become more pronounced as his personal sense of “self‐uniqueness” is decreased. Greater preferences for and more favorable valuations of unavailable messages relative to available messages were also expected, independent of subjects’ anticipated familiarity or unfamiliarity with arguments contained in the messages. Experimental subjects received fictitious test results describing them as extremely high, high, or low in personal uniqueness compared with their peers. They then received information about four different messages; the messages being described as either available or unavailable to them and to others, and as containing either familiar or unfamiliar arguments. Subjects indicated their preferences for and valuations of each of the four different messages. The hypothesized effects were obtained. 相似文献

In this study, I demonstrate the consequences of the triumph of neoliberalism and media deregulation for democracy. I argue that the tremendous concentration of power in the hands of corporate groups who control powerful media conglomerates has intensified a crisis of democracy in the United States and elsewhere. Providing case studies of how mainstream media in the United States have become tools of conservative and corporate interests since the 1980s, I discuss how the corporate media helped forge a conservative hegemony, failed to address key social problems, and promoted the candidacy of George W. Bush in the 2000 US presidential election. 相似文献

The present study used cultivation theory to explore the relationships between celebrity media diet and materialism for a sample of 224 emerging adults. Results indicated main effects between both celebrity magazine consumption and celebrity TV news consumption on materialism. Total celebrity media diet was also significantly related to materialism. Findings suggest that a media diet high in celebrity culture and lifestyle has significant impact on emerging adults’ preoccupation with consumerism, particularly for women. This research contributes to a growing body of literature on the effects of a celebrity-saturated media environment and the cultivation of materialistic attitudes. 相似文献

The development of digital technologies for the production, processing, dissemination and use of information is leading to the emergence of a new society based on a far reaching transformation in the relationship between people and institutions and on a radical change in many professional, economic, educational or cultural practices. The crucial question facing us today is whether our traditional societies are ready for such a shift in ways of thinking, communicating and acting. Are people sufficiently aware and adequately equipped to become citizens of this new information society? Are they prepared to be active, efficient and responsible participants in the new communities living on information exchange? Are we really ready to be part of a new culture based on a swifter and broader flow of information, ideas and knowledge? The development of that special culture, or infoculture, depends first and foremost on education, both general and vocational, and on initial and continuing training as well as on raising awareness among the public at large. Achieving a real infoculture calls for full-scale mobilization of all those who in their various ways are involved in the information society. Partnerships must be encouraged; national, regional or world projects must be given support; there is more than ever a need for a new form of solidarity to develop the infoculture. 相似文献

Nearly 20 years after the Telecommunications Act of 1996, it is unclear how its mandates influence current parents’ mediation behavior. Parents of 2- to 17-year-old children (N = 1,431) were surveyed about their awareness and perceptions of the TV ratings system and use of the V-chip. Most (81%) parents knew about the ratings system and found it to be only “somewhat useful.” Only 16% of those parents had ever used the V-chip. Ratings awareness and perceptions and V-chip use varied with family characteristics. Policymakers should revisit how to provide better tools for mediating children’s viewing in this new information age. 相似文献

This article addresses an approach to library services for people who are incarcerated that meets the situated information needs and desires of people within jails and prisons. By creating a flow of information between LIS students and individuals who are incarcerated through a Reference by Mail program, resources available to incarcerated people are increased while students engage in a humanizing and self-reflexive project, with the understanding that the regulation of information within jails and prisons has lasting effects for the life chances of incarcerated people. 相似文献

Through discussing how the Polite Principle rescues the Cooperative Principle in English and Chinese .this thesis proves that PP is suitable both in English and Chinese .What＇s more, Chinese people has the thoughts and tradition of polite- ness. However when Chinese people confront with English they are easy to fall into embarrassments. This thesis points out two reasons of pragmatic failure. One is the cultural difference and the different use of PP in Chinese and English. The other is the unsuitable education system and belief. Finally, this thesis proposes three kinds of methods： 1. The supplement of au- thentic material which can reduce inauthennc input, improve cultural awareness and stimulate learning motivation.2.Changing the classroom from the teachers＂ arenas to students＇ forums 3. Learning English on the mteruet. 相似文献

ABSTRACTMassive open online courses (MOOC) are considered a modern e-learning technology that was initiated by the Malaysian higher education in 2015. The current literature on MOOCs, covering research relating to its effectiveness to accommodate different students’ abilities showed conflicting results in this regard. With limited studies on MOOCs’ effectiveness in Malaysian higher education, this study explored current opportunities, challenges, and solutions of using MOOC in the Malaysian higher education institutions. Instructors from various teaching backgrounds were interviewed to respond to these concerns. The study found that the major challenges faced by instructors when using MOOC were redundancy, lack of facilities and exposure, incompetent knowledge in MOOC course design and development, and insufficient leadership and capacity-building programmes. Therefore, possible solutions to these challenges were identified and discussed. These findings can help the policy makers explore strategies for the future development, implementation and success of MOOC in the context of higher education in Malaysia.Abbreviations: MOOC: Massive Open Online Courses; cMOOC: Connectivist Massive Open Online Courses; xMOOC: eXtended Massive Open Online Courses; ahMOOC: adaptive hybrid Massive Open Online Courses; LMS: Learning Management System; MQA: Malaysian Qualifications Agency; STEM: Science, Technology, Engineering, and Mathematics 相似文献

The present study reports the online business database holdings of the top academic institutions in the United States, which databases are paid for by which entities on campus, and some of the most common and most desired business databases. An invitation to participate in an online survey was sent to 91 top institutions of which 39 institutions participated. The results show a wide variety of information resources are considered core business resources in contemporary business librarianship and imply an increasing importance of cost sharing in providing the databases to support research and efforts to commercialize research. 相似文献

Throughout American history that form of Protestantism that designates itself and is publicly conceived as “old‐time religion” has regularly been the innovator in the area of media. In stark contrast, its more staid establishment counterpart has tended to be antagonistic to these new media, dismissing them with harsh theological and aesthetic judgments. In this process, the self‐proclaimed theological conservatives actually behaved in remarkably adaptive and imaginative ways, while the self‐proclaimed liberal establishment often acted as the cultural conservator, pressing for the preservation of the status quo. This article seeks to understand why those Protestants who define themselves as “modernist” and “adaptive” have been far less successful in using the media than their conservative “anti‐modernist” counterparts. The focus is upon a case study—the reception of television by the Broadcast and Film Commission of the National Council of Churches. The conclusion is ironic: those Protestants who depended upon “modern,” “social scientific” criterion to guide their television policies fundamentally misunderstood the power of television and its impact upon society. 相似文献

Trade and scholarly publishers often urge academic authors to reach out to an audience beyond their peers. One obstacle to expanding the audience for new scholarship is the widespread belief that it requires "pandering to the lowest common denominator," or "dumbing down," and that the scholar turned "popularizer" will be shunned by the academy. Where did this academic myth come from? Is there any truth behind it? What can an editor say to the academic author who fears that publishing success will spell the end of academic respectability? 相似文献
