When people perceive events that conflict with their expectations they can easily express their agitation and concerns online and likely find others who share their opinion. When large quantities of messages containing negative word-of-mouth suddenly spread in social media we speak of an online firestorm. By covering the outcry, journalists elevate it onto a mainstream communication platform and support the process of scandalization. Content analysis was used to explore how journalists, working for German-language media, cover this phenomenon. Over a period of 16 months, 130 online firestorms were identified and analyzed. Based on a typology of online firestorms, we have found that the majority of cases address events of perceived discrimination and moral misconduct aiming at societal change. Vilification of the organization or person occurred to a much lesser extent. Thus, journalistic coverage of the phenomenon focuses on the rectification attempts of an aroused public. Image-repair responses of the firestorm objects are quoted by journalists in about half of the articles, thereby providing some balanced reporting about the online criticism. This study provides an initial insight into how online firestorms are used as a topic of news coverage by journalists and explores journalists’ contribution to attempts of online scandalization. 相似文献

ABSTRACTSecond-level agenda-setting suggests that news media influence how we think. As a case study examining the nature and effects of mainstream news media’s coverage of the 2015 Apple/FBI dispute about data privacy versus national security, this study found via content analysis that a majority of articles covering the dispute (73.7%) made the same potentially misleading claim about how the American public feels about the dispute. Nearly half (45.6%) of those articles made public opinion claims without offering empirical evidence, and almost all articles (97.4%) that cited the Pew survey appeared to have inadvertently created an unsubstantiated social reality. Then, this study found in a subsequent experiment that, consistent with impersonal influence, the above-mentioned news portrayals significantly affected the participants’ view on Americans’ collective opinion towards the Apple/FBI dispute. The long-term effect of this journalistic oversight is notable. Theoretical implications and practical recommendations for future science communication in the news are discussed. 相似文献

Many altmetric studies have analyzed which papers were mentioned how often on Twitter (one of the most important altmetrics sources). In order to study the potential relevance of tweets from another perspective, we investigate which tweets were cited in papers. If many tweets were cited in publications, this might demonstrate that tweets have substantial and useful content. Overall, a rather low number of citations to tweets (n=13,149) by less than 7,000 papers was found. Most tweets do not seem to be cited because of any cognitive influence they might have had on studies; they rather were study objects. Thus, this study does not support a high relevance of tweets (for research). Most of the papers that cited tweets are from the subject areas Social Sciences, Arts and Humanities, and Medicine. Most of the papers cited only one tweet. Up to 65 tweets cited in a single paper were found. An author keyword analysis revealed that the single largest topic seems to be the COVID-19/corona pandemic. 相似文献

This study is a social media analysis on the use of Twitter at Historically Black Colleges and University (HBCU) libraries. While information science researchers have begun examining how libraries use social media, the vast majority of these studies are situated at large flagship research-intensive universities. Additionally, there currently exist deficiencies in research on social media deployment at HBCU libraries. We leverage, the IBM Watson's analytic engine, to systemically examine over 23,000, tweets over an eighteen-month period, around a set of objective measures including propagation of retweets and sentiment to assess follower engagement. The analysis found little evidence of follower engagement with library generated content. However, we observed a substantial volume of library tweets coalesced around institutional boosterism, rather than library related phenomena. This non-library related content represented the vast majority of retweets, but paradoxically was propagated by non-followers. Additionally, tweets relating to institutional boosterism produced the most positive sentiment within the data. 相似文献

AbstractA small but significant proportion of the archaeological iron objects in the British Museum collection have been problematic in that some of them have required repeated treatment. The deterioration of iron objects during storage was studied using microscopy, Raman spectroscopy, X-ray diffraction, scanning electron microscopy/energy dispersive X-ray analysis, X-ray fluorescence spectroscopy and ion chromatography. A total of 125 iron objects, including 56 from two British Roman sites and 69 from three Anglo-Saxon sites, were studied. Both surface corrosion and corrosion layers on polished cross-sections were investigated. The study revealed that the present condition of the iron objects varies; some are in a stable condition and others have been deteriorating, with pitting and weeping present on the surface. No treatment method had stopped corrosion for every object, although the alkaline sulphite treatment seemed to be more effective than the other methods. The results also showed that chloride ions can be present at the interface of the metal and inner corrosion layers. It is recommended that iron objects which have been mechanically cleaned without desalination treatments are kept in a dry environment to prevent further deterioration. 相似文献

ABSTRACTThe National Museum of Ethnology, Osaka, Japan, collects a vast amount of materials and information related to peoples’ life and culture, and makes them available to society through exhibitions and other activities. The number of collected items is increasing every year: 343581 objects have been collected from Japan and abroad as of March 2017. The continuous efforts have been necessary to improve storage conditions and to save space for both general and special storerooms. The former, which account for 90% of the storage capacity of the museum, are air-conditioned during working hours, with temperature and relative humidity (RH) settings varying with the seasons. The latter, which house objects for which strict conservation conditions are required, are air-conditioned for 24 hours with fixed settings of temperature/RH throughout the year determined by the nature of the materials from which the objects have been made or formed. Storage re-organization began with special storerooms, for which the number of objects and the storage area are far more limited in comparison with the general storerooms. The storage shelves for fur/skin/feather (almost 1000 objects) and for carpets (almost 550 objects) were all renewed in FY2007/2008. Then two large-scale innovation projects for general storerooms were conducted: construction of storage areas for ships equipped with a CO2-based and anoxic pest treatment facility (FY2015), and a complete refurbishing of the general storeroom for large objects (FY2016). Windows were set in the corner of this storeroom to provide visitors an opportunity to view and learn about the museum activities. In parallel to the above projects, daily storage improvement efforts have been undertaken. Storeroom No. 3, chosen as an example for general storerooms for small and medium-sized objects, was used to investigate the range of issues related to the shelving arrangement and storage conditions. Guidelines for storage re-organization were formulated according to the results of the investigation and according to the experiences gained through the renewal of special storerooms. Storage re-organization undertaken in storeroom No. 3 was conducted for 6 years at the rate of around 2000–4000 objects per year with a low budget and with reuse of existing shelves. In FY2016, all objects in storeroom No. 3 were properly redistributed. About 40% of the storage space was saved. Over these 10 years of storage re-organization, preventive measures have been taken for sustainable collection management. As early as FY1992, pest trap investigations have been carried out seasonally. Since FY2004, the results of investigations have been analyzed using a customized computer program. Subsequently, appropriate integrated pest management measures have been taken. In addition, since FY2014, energy-efficient air-condition control has been adopted for general storerooms. It consists of switching off air-conditioning in spring and autumn, and of starting it only when the temperature or RH values become too high in summer or too low in winter. Because the turning-off of air-conditioning causes comparable or even less climatic fluctuation, it was considered acceptable both economically and from a conservation perspective. It is estimated that turning the air-conditioning off during transitional seasons brings cost savings of about 3000000–4000000 JPY (about 26800–35700 USD as of 23 September 2017) per annum, which accounts for almost 30% of the electricity expenditures for all general storerooms. 相似文献

To discourage faculty members from publishing in questionable journals, tenure and promotion standards in which the librarians play an active role can been developed. These standards have been effective in terms of identifying publications in questionable outlets. However, we need to explore how these systems are perceived by the main actors in research, which are the researchers. This study explores the perception of the researchers at a university in Ghana who have been evaluated by a system implemented to discourage publishing in questionable publication outlets. We collected data using an online, largely qualitative questionnaire distributed to all faculty members that had applied for promotion since the implementation of the verification process. The results show that the majority of the faculty members are satisfied or very satisfied with the new tenure and promotion standards. There are differences across faculties, and this seems to be tied to concerns about the choice of publication outlets. Furthermore, the dissatisfied faculty members are concerned with the role of the library in the verification process whereas the satisfied trust the judgement of the librarians. We discuss implications of the results as well as future development of the standards. 相似文献

AbstractAt the University of Wollongong (UOW) Library we have been exploring ways to deliver information and digital literacy resources at point of need for students. Aligned with the University’s strategic direction, the Future Ready Library Strategy points to a digital first mindset and its application to services and resources offered to the UOW community. Combined with the need to embrace the real life challenges faced by higher education students in Australia today, this has led us to develop a suite of digital learning objects in collaboration with teaching academics that can be delivered at scale, enabling a sustainable way to target student needs. In this article, we discuss the drivers that have brought UOW Library to this point and outline the model for learning and teaching support for our academic community into the future. 相似文献

Linkage analysis as an aid to web search has been assumed to be of significant benefit and we know that it is being implemented by many major Search Engines. Why then have few TREC participants been able to scientifically prove the benefits of linkage analysis in recent years? In this paper we put forward reasons why many disappointing results have been found in TREC experiments and we identify the linkage density requirements of a dataset to faithfully support experiments into linkage-based retrieval by examining the linkage structure of the WWW. Based on these requirements we report on methodologies for synthesising such a test collection. 相似文献

In this study, we investigate differences in occupational status between women and men, and between ethnic minority and majority members, by means of a content analysis of Belgian prime-time television in 2013. We evaluate the accuracy of these television portrayals using interreality comparison strategies. Results indicate that although in television content women obtain higher average scores for occupational status than men, this is mainly due to the underrepresentation of women in low-status occupations. Although previous studies focused on the absence of women in high-status jobs, this analysis shows for the first time that women are also absent in low-status manual and industrial jobs. Ethnic minorities have lower average scores for occupational status. Moreover, interaction terms made clear that this especially holds for female ethnic minorities, suggesting that mechanisms of intersectionality are at play. In general, the labor world as portrayed on television diverges strongly from the real labor world. 相似文献

AbstractFour iron meteorite fragments and 13 archaeological iron objects were exposed to a lowpressure hydrogen plasma for up to two weeks in a pilot apparatus. In the experiment the objects acted as cathodes in a 600–1600V d.c. electrical field. While the chlorine-containing β-FeOOH, akaganeite, was present in all objects before the test, no akaganeite and no chlorides were present afterwards. The objects, including one meteorite which had been exposed for more than 5000 years to seawater, were found to be stable after the glow discharge treatment. The major mineral after treatment was identified as magnetite, and the objects generally assumed an iron-grey surface colour. No sputtering and no reduction to free iron took place under the test conditions, operating at or below 120°C and at pressures of O·4–1mb hydrogen. 相似文献

A content analysis of rap music videos aired on BET, MTV, and VH1 examined the occurrence of controversial themes, gender differences, and skin tone distortion. The results of this study found that current rap music videos have placed an emphasis on themes of materialism and misogyny. Additionally, men and women in the videos differ in their portrayal of these themes. Specifically, female characters are significantly more likely to appear as objects of sexuality. Men and women also differ in their appearance with more African American females appearing to have Eurocentric features. Implications and suggestions for future research are discussed. 相似文献

Targeting, to aim a crosshair at an object, is the most basic skill for a gamer to survive from enemies, solve puzzles, and make a story unfolded in videogames. As the trigger for the game objects’ reciprocal operations, this simple action functions to individuate the objects kept in their abstract initial state into the concrete functional units participating in a topological network operational in a videogame to achieve the gamer’s goal. In today’s open-world games, these objects disclose their agencies through the auras perceivable when the player characters use certain magical skills and technological aids. In this genre, a gamer’s narrative and ludic experiences, all triggered by one’s performance to target at the objects on the human side of the interface, are translated, on the machinic side, into the topological transformations of the objects’ network. As an experiment for a nonhuman turn in videogame studies, this essay examines how this topological network behind an open-world mobilizes the ludic and narrative behaviors of gamers for its never-ending transformation. 相似文献
