Previous studies have examined the publication patterns of library and information science (LIS) school faculty with respect to the effects of the presence of a Ph.D. program in the school on overall publication productivity. These studies have come to different conclusions and are not strictly comparable due to differences in methodology and data sets. Online indexes were searched to compile a database of 7,937 publications from the 607 faculty members teaching in accredited North American LIS schools. Analysis of these data shows that publication productivity is generally higher in LIS schools with a Ph.D. program than in those without, that Carnegie Research Universities I schools tend to publish more, and that although the Ph.D. and master's granting schools devote about the same proportion of their total output to refereed journals, the Ph.D. institutions have a greater output of refereed articles. 相似文献

To understand the broadcast segments of multi‐industry companies, it is important to consider the revenue demands of their parent companies. This article develops a methodology for analyzing the profitability of broadcast and non‐broadcast segments and applies that methodology in an examination of publicly held corporations. 相似文献

ABSTRACTThis essay invites us to consider the need to rethink culture and some theoretical/intellectual assumptions in Cultural Studies when we bring up the issue of the “Global South.” The essay makes a case for “going South” in Cultural Studies. It advances a notion of the South that is based on a frame of dispossession. The first section offers a historical overview of the Global South and considers where the Global South is today. The second section attempts to rethink the notion of ‘culture’ and some intellectual orientations in Cultural Studies when we move to the Global South. 相似文献

AbstractAcrylic polymer dispersions, regularly used as artists' media or varnishes, were monitored for the development of yellow discoloration under natural aging conditions for a period of two years. Films of a number of water-based acrylic artists' media were kept under visible light of either moderate (150 lux) or low (50 lux) intensity (cycled on 10 hours per day) and were compared to films kept in dark storage, which have been observed to yellow. Results after two years show that exposure to visible light at 150 lux effectively prevented film discoloration in a number of products, and seemed at least to slow the rate of yellowing in others. Exposure to low-intensity (50 lux) lighting was found to be less effective in preventing this yellowing. 相似文献

AbstractTesting of chemical stabilization treatments and desiccated and anoxic storage microclimates for the protection of archaeological iron stored in unsuitable climatic conditions was carried out by the conservation department of the Japanese Institute of Anatolian Archaeology at the Kaman-Kalehöyük excavation in Turkey. The chemical stabilization treatments involved alkaline sulfite, barium hydroxide and sodium hydroxide. Environmental stabilization was explored using RP-A oxygen scavengers in Escal® bags as part of the Revolutionary Preservation System (RP System®) manufactured by Mitsubishi Gas Chemical Company, Inc. The efficiency of the chemical treatments was examined by comparison with mechanically cleaned iron objects. The efficiency of the storage systems was determined by comparing the chemically and non-chemically treated objects in the RP System® using RP-A scavengers and in polyethylene ziplock bags containing silica gel. The efficiency of these treatments and storage systems was examined and assessed at Kaman after a period ranging from 7 to 9 years. The anoxic and desiccating properties of the RP System® resulted in superior protective qualities over polyethylene bags with silica gel. The RP System® compensated for inadequate chemical stabilization and protected iron that had not been chemically stabilized. 相似文献

This paper uses time series data on UK book sales to establish what correlation exists between the national income of a country and its sales of books. This is tested by comparing series data in real terms for GDP per capita and for various data series for the UK market, including sales invoiced by publishers and point of sale data on consumer purchasing. The first period, from 1985 to 1999, shows a strong relationship between total sales and GDP per capita. In the second period, from 2001 to 2015, the link appears to disappear when we examine invoiced sales from publishers, even before the impact of the 2008 crisis. This is also including the growth of digital sales towards the end of the period. The direct consumer data shows sales tracking GDP until the onset of the financial crisis; thereafter the only trade sector to have kept pace with GDP is children’s, and this contrasts with the areas of adult fiction and non-fiction. Have we therefore seen a structural shift in the book market? If we have passed peak book, what has brought about this uncoupling of book sales from economic growth? Factors are considered including changes in retail, competition from other media, and a prioritization of experience over the accumulation of stuff. 相似文献

How well do governments comply with their own transparency statutes? Alarmingly, answers to this question are in short supply because of patchy comparative data. This study begins to address this gap by analyzing an exhaustive compilation of 265 transparency compliance evaluations (i.e. audits) authored by NGOs, academics, and government oversight authorities across Latin America between 2003 and 2018. Aggregating data on patterns of evaluation and public sector compliance with transparency statutes, we find modest increases in compliance over time, strikingly low compliance with passive transparency compliance (i.e. governmental responses to citizen requests) at the local versus national levels of government, and significantly higher compliance scores when government oversight agencies act as evaluators. Our data also reveal worrying gaps in evaluation efforts. Evaluators tend to focus far more on active transparency (i.e. website-based disclosure) than passive transparency, more on national level governments than subnational governments, and preponderantly on the executive as opposed to legislative or judicial branches of government. Textual analyses show that education is the most evaluated policy theme, with financial policies and social services close behind. In presenting the first large-scale cross-national assessment of transparency compliance, the current study brings to light trends in the effectiveness of transparency regimes and patterns of transparency evaluation across Latin America. 相似文献

This author is in general agreement with the arguments in Bostrom's () essay concerning theory–data interaction. Nevertheless, an examination of the issues raised in the essay from the standpoint of scientific realism lead to two different conclusions. First, the opening rationale is based on a nondefensible distinction between empiricists and interpretivists. Second, debates among paradigms are based on real ontological and epistemological differences, and the scientific realist's view of theory–data interaction accepts the validity of these differences. 相似文献

Little is known about how public sector organisations capitalise on the potential of social networking sites (SNSs) as communication channels. Previous research is short on theoretical models and managerial insights into the success of local governments' online communication strategies. The purpose of this study is to explore how successfully local governments utilise SNSs for managing their external communication with citizens. Using a multi-method analysis of 15,941 posts and 19,290 comments on the Facebook pages of the 25 largest German cities, we make five contributions to research and practice. First, we analyse the properties and topics of government posts to draw a rich picture of how local governments use Facebook as a communications channel. Second, we conceptualise success in governments' online communications in terms of the frequency and polarity of citizens' reactions, which we use for third, evaluating government communication behaviour in SNSs. Fourth, we identify which benefits SNSs offer that traditional communication channels do not provide. Fifth, we offer guidelines for improving the online communication strategies of local governments using SNSs. 相似文献

Between 2010 and 2015, more than 30 college radio stations either went off air, transferred their licenses, or entered into programming or shared-time agreements. Among these are Vanderbilt University’s KRVU 91.1 FM, University of San Francisco’s KUSF 90.3 FM, Rice University’s KTRU 96.1 FM, and Georgia State University’s WRAS 88.5 FM. In what seems to be a shrinking presence of college radio on the FM dial, this study examines national and local news coverage of recent college radio shutdowns, transfers, and agreements to understand how these events are being presented in the news media. Findings suggest themes in news coverage includes a great deal of attention to the student, alumni, and community responses to station closures and transfers, but limited attention to reasons for the closures and transfers. University administrators were the most commonly quoted or referenced sources in the sample; students, alumni, community, faculty, and staff held significantly smaller shares of voice. Questions about the coverage of college radio closures and transfers as well as college radio’s future viability are discussed. 相似文献

Requesting Internet platform providers to remove content is one of the common approaches for government worldwide to regulate online incivility. This study investigates the driving forces behind the variation in the number of uncivil content removal requests across countries. By connecting data from the 2017 Google transparency report to a host of societal level indicators, this study finds that the quantity of uncivil content removal requests is related to both social reality and political value factors. Countries with high levels of social vulnerability and low levels of freedom of speech tend to send more requests to Google for removing online incivility. However, democratic and non-democratic societies show different patterns: social reality and political values play important roles in democratic societies while in non-democratic societies, social reality is the only determining factor. 相似文献

The turn to oral history in Qatar and the Arabian (also known as Persian) Gulf is not a rejection of traditional archival authority as has been the case in other parts of the world. In the Gulf, oral history has been embraced out of a desire to fill the silences of the largely unwritten record attributable to previous low levels of literacy and strong oral traditions in the region. Today, oral history is seen as the best method to capture details about traditional ways of life during the pre-oil era. After discussing archival concerns about the evidentiary nature of oral histories, this paper explores how it has come to be a crucial documentation tool in the Gulf, adapted to the specific nation building and cultural heritage priorities of the region. 相似文献

ABSTRACT In the ten years since the International Conference on the Principles and Future Development of AACR, long-standing debates have continued as to whether or not to have a “main entry,” and whether or not to exercise the rule of three to limit the number of headings or access points in certain cases. Recent proposals from the Joint Steering Committee for Development of RDA have recommended a change in “main entry” terminology to “primary access point,” and the elimination of the rule of three. This article explores how and why these shifts have occurred. 相似文献

This paper analyzes the implementation of new intermunicipal structures in Italy to support the development of E-Government in the country's peripheral areas. Our exploratory case study, conducted in the Piedmont Region, shows that intermunicipal collaborations can facilitate the coordination of interdependent subjects, rationalize existing resources (e.g., through the reuse of application software solutions), and prevent the dispersion of federal government funds. Nevertheless, intermunicipal collaborations alone do not seem to have the power needed to ensure that decisions made at the central level will automatically translate into concrete and binding commitments for the municipalities involved. From a methodological standpoint, the article makes use of the analytical frameworks offered by organization science to interpret the effects of collaborative arrangements on E-Government implementation. 相似文献
