The Hirsch index and the Egghe index are both numbers that synthesize a researcher's output. The h-index associated with researcher r is the maximum number h such that r has h papers with at least h citations each. The g-index is the maximum number g of papers by r such that the average number of citations of the g papers is at least g. Both indices are characterized in terms of four axioms. One identifies outputs deserving index at most one. A second one establishes a strong monotonicity condition. A third one requires the index to satisfy a property of subadditivity. The last one consists of a monotonicity condition, for the h-index, and an aggregate monotonicity condition, for the g-index.  相似文献

The national survey, conducted for all art museums in the United States and Canada, resulted in 252 questionnaires, of which 166 were computer-user museums with acceptable questionnaires. The institutions using computers averaged 2.2 million in budget and had a median membership level of 860. Museums were divided in small, medium, and large budget categories by the budget ranges of2.2 million in budget and had a median membership level of 860. Museums were divided in small, medium, and large budget categories by the budget ranges of 0-210,000, 211-817,000, and211-817,000, and 818,000+.  相似文献

This paper presents the first meta-analysis of studies that computed correlations between the h index and variants of the h index (such as the g index; in total 37 different variants) that have been proposed and discussed in the literature. A high correlation between the h index and its variants would indicate that the h index variants hardly provide added information to the h index. This meta-analysis included 135 correlation coefficients from 32 studies. The studies were based on a total sample size of N = 9005; on average, each study had a sample size of n = 257. The results of a three-level cross-classified mixed-effects meta-analysis show a high correlation between the h index and its variants: Depending on the model, the mean correlation coefficient varies between .8 and .9. This means that there is redundancy between most of the h index variants and the h index. There is a statistically significant study-to-study variation of the correlation coefficients in the information they yield. The lowest correlation coefficients with the h index are found for the h index variants MII and m index. Hence, these h index variants make a non-redundant contribution to the h index.  相似文献

This work maps and analyses cross-citations in the areas of Biology, Mathematics, Physics and Medicine in the English version of Wikipedia, which are represented as an undirected complex network where the entries correspond to nodes and the citations among the entries are mapped as edges. We found a high value of clustering coefficient for the areas of Biology and Medicine, and a small value for Mathematics and Physics. The topological organization is also different for each network, including a modular structure for Biology and Medicine, a sparse structure for Mathematics and a dense core for Physics. The networks have degree distributions that can be approximated by a power-law with a cut-off. The assortativity of the isolated networks has also been investigated and the results indicate distinct patterns for each subject. We estimated the betweenness centrality of each node considering the full Wikipedia network, which contains the nodes of the four subjects and the edges between them. In addition, the average shortest path length between the subjects revealed a close relationship between the subjects of Biology and Physics, and also between Medicine and Physics. Our results indicate that the analysis of the full Wikipedia network cannot predict the behavior of the isolated categories since their properties can be very different from those observed in the full network.  相似文献

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.  相似文献

Social media are increasingly being used as sources in mainstream news coverage. Yet, while the research so far has focused mainly on the use of social media in particular situations, such as breaking news coverage, during crisis news events or in times of elections, little attention is paid to journalists' routine, day-to-day monitoring of social media platforms. The aim of this study is to examine the use and selection of social media as sources in routine newspaper coverage. First, it presents a quantitative overview of all the articles published between January 2006 and December 2013 in the print editions of two Flemish (north Belgian) quality newspapers, De Standaard and De Morgen, that explicitly refer to Facebook, Twitter or YouTube. Next, a content analysis is conducted of a sample of newspaper articles published in 2013 that explicitly mention Facebook, Twitter or YouTube as sources of information. The goal of this content analysis is to examine the different appearances and functions of social media references in the news. The study thus provides a first insight into Belgian newspaper journalists' regular sourcing routines in relation to social media.  相似文献

The account sequence is proposed as a mechanism by which parties to initial encounters deal with the discovery of dissimilarity and other conversational “disagreeables.” A classification of offense, reproach, account, and evaluation forms is offered. The recorded conversations of 50 pairs of strangers were examined for the presence of account sequences. Each sequence was coded for type of offense, type of reproach, account strategy, and form of evaluation of the account. Persons were found to be likely to omit accounting when reproached for interaction offenses, work/school offenses, and personal identity offenses, or when the form of the reproach was a direct rebuke or imputation of moral/intellectual superiority of the reproacher. Excuses were most likely to be offered for offenses of taste/attitude/belief, work/school, and personal identity. Reproached individuals refused to account for personal identity and taste/attitude/belief offenses more often than other types; they also refused when the reproach forms direct rebuke, moral/intellectual superiority, and direct request for account were employed. Evaluation behavior was shown to vary only with the immediately preceding account. Honoring was the evaluation form most often associated with the account strategy excuse. Evaluators were significantly likely to retreat if the account‐giver conceded or justified. When the account strategy was doesn't account, justify, or refuse, there was a significant tendency for evaluators to reject/take issue/reinstate the reproach. Finally, when the reproached individual did not account, one evaluation form significantly associated with the omission was drop/switch topic.  相似文献

Abstract

The two Stangengläser, tall cylindrical vessels from the beginning of the seventeenth century, are described in detail. The severely damaged Stangengläser, decorated with diamond-point engraving and cold-painting, were challenging to treat. Research preceding the conservation revealed differences in decorating techniques. Samples of the paint layers were analyzed using micro-Fourier transform infrared spectroscopy. Two layers of resinous varnish with a middle layer of paint containing a plant gum were found on the Stangenglas with Allegory of Caritas and Zierotin coat of arms. In the plain paint layer of the Stangenglas with dancing couples, egg white was identified as the binder. The glasses, analyzed using scanning electron microscopy with energy dispersive X-ray spectrometry, had similar potash–lime–silica compositions, which seems to be characteristic for glass from Bohemian lands. Results of analysis contributed to the discussion about the possible provenance of the Stangengläser, the glassworks at Wilhelmberg, South Bohemia.  相似文献

The Cincinnati Post published its last edition on New Year's Eve 2007, leaving the Cincinnati Enquirer as the only daily newspaper in the market. The next year, fewer candidates ran for municipal office in the Kentucky suburbs most reliant on the Post, incumbents became more likely to win reelection, and voter turnout and campaign spending fell. These changes happened even though the Enquirer at least temporarily increased its coverage of the Post's former strongholds. Voter turnout remained depressed through 2010, nearly three years after the Post closed, but the other effects diminished with time. The authors exploited a difference-in-differences strategy and the fact that the Post's closing date was fixed 30 years in advance to rule out some noncausal explanations for their results. Although their findings are statistically imprecise, they suggest that newspapers—even underdogs such as the Post, which had a circulation of just 27,000 when it closed—can have a substantial and measurable impact on public life.  相似文献

The study reports on a meta-analysis of attempts to correct misinformation (k?=?65). Results indicate that corrective messages have a moderate influence on belief in misinformation (r?=?.35); however, it is more difficult to correct for misinformation in the context of politics (r?=?.15) and marketing (r?=?.18) than health (r?=?.27). Correction of real-world misinformation is more challenging (r?=?.14), as opposed to constructed misinformation (r?=?.48). Rebuttals (r?=?.38) are more effective than forewarnings (r?=?.16), and appeals to coherence (r?=?.55) outperform fact-checking (r?=?.25), and appeals to credibility (r?=?.14).  相似文献

ABSTRACT

Using a methodology inspired by structural narratology and by James Hamilton’s [2016. Democracy’s Detectives: The Economics of Investigative Journalism. Cambridge: Harvard] economic analysis of investigative journalism, this paper identifies a set of 14 recurring structural and formal elements (plot events, character types and functions, visual iconography) that constitute a fable about investigative journalism. The fable structure is applied to analyze six diverse films about investigative journalism produced in the US in the last 40 years. The films include two instantiations of successful investigative journalism (All the President’s Men, Spotlight), two cases where conflict between journalists and corporate managers diminished the impact of the investigation (Good Night and Good Luck, The Insider), and two instances of a counter-fable of failed investigative journalism (Truth, Kill the Messenger). The paper argues that the films’ representation of investigative journalism influences public perceptions of investigative journalism. It also speculates about the factors that will influence investigative journalism and its representations in the current political context in the US.  相似文献

The gellan hydrogel is used as a cleaning agent for paper artworks. The purposes of this work were to give the gellan hydrogel both a microbial resistance and a cytocidal action against the biodeteriogens using hydrolates. Broth microdilution assays were performed to identify the fungicidal action of 16 hydrolates vs 3 fungal strains. The study concerned the Minimal Fungicidal Concentration and pH, colour, and ultra-structural variations on all paper samples, by placing them in contact with GELYD (GELlan?+?hYDrolat). The in vitro tests showed that eight out of 16 hydrolates strongly inhibited fungal growth, but only two of them (Monarda fistulosa, Citrus aurantium subsp amara) showed in situ fungicidal action. Data indicate a new and interesting eco-innovative use of hydrolates, since GELYD is able not only to clean paper artworks, but also to kill the fungal cells present on paper that are potentially harmful for paper and operators.  相似文献

This paper examines representations of mental illness in popular film, particularly Richard Ayoade’s The Double and Dan Gilroy’s Nightcrawler. As I argue, both films trouble typical Hollywood narratives of mental illness by situating schizophrenia and psychopathy, for instance, within a socioeconomic context, specifically relations of production under late capitalism and the unfettered self-interest of neoliberalism. If mental illness is a product of the postindustrial workplace in The Double, it becomes a prerequisite for success in Nightcrawler, providing a cinematic depiction of mental illness at odds with the “personal pathology” paradigm that dominates the current neoliberal landscape.  相似文献

With conference season upon us, consideration is given to the importance of subject‐specific and library association conferences. The biennial Health Libraries Group (HLG) conference meets both these criteria and takes place in Greater Manchester in July. The conference provides an opportunity for peer‐to‐peer learning, identifying new trends and professional rejuvenation. An open invitation is given to attend the Health Information and Libraries Journal‘Writing for Publication’ workshop at the HLG conference. An overview of three bursaries available from the Health Libraries Group and Library and Information Research, both groups of the UK Chartered Institute of Library and Information Professionals (CILIP) is provided. The bursaries offer opportunities to cover the costs of registration and travel expenses to national and international conference.  相似文献

A Rare Find     
《资料收集管理》2013,38(3):45-51
Baltimore writer Binnie Syril Braunstein has authored three romance novels and thirty-six published short stories. The novels (The Color of Love, Out of the Darkness, and Baby Love) were published by Harlequin Temptation under her pseudonym, Binnie Syril. She is also a book collector; her collection includes (among other things), over one-hundred ten (110) different editions of her favorite fairy tale, "Beauty and the Beast." In doing the research for her fifth book, Ms. Braunstein became aware of the very strong link between collecting and creating. The article which follows includes an examination of that link, a brief discussion of romance novels in general, and a preview of her new book proposal, tentatively titled, A Rare Find.  相似文献
