Abstract

The study focuses on the range of pigments and media that the Italian artist Lucio Fontana (1899–1968) employed for selected works dating between 1949 and 1968. Samples were taken from ten groups of works, all on canvas support, as well as from painting equipment that survived in the artist's former two studios. Techniques of analysis used were pyrolysis-gas chromatography–mass spectrometry for media identification, and laser desorption ionization time-of-flight mass spectrometry and Raman microspectroscopy for pigment identification. Fontana's reputation as a daring and experimental artist, best known for his group of slashed paintings called tagli, is seen to correspond with certain unusual material choices he made. The study also points to several links that exist between seemingly unrelated cycles. These links are, among others, based on experiences with in part novel media such as oil, alkyd, polyvinyl acetate, acrylic, acrylic–vinyl, and mixtures of them. With regard to pigments, the selection of samples showed that they were mostly of a synthetic organic nature.  相似文献

ABSTRACT

Purpose: The present study aims to determine and compare the views of directors and users of public libraries on the use of social media for the marketing of library services.

Methodology: Data collection was done through two researcher-made questionnaires, one from the viewpoints of directors and one investigating the views of users. The questionnaires’ validity was done by four libraries and Information Science professionals, and the reliability was determined by the Cronbach’s alpha coefficient. The statistical population of this research is made up of all directors and users of 12 public libraries of the city of Isfahan, one of the largest cities in Iran.

Findings: In users’ viewpoints, the “interaction capability” is the most important feature that social media marketing can have in libraries. From the viewpoints of the directors, “creating a true picture of the role of the library” and “informing users about library services” are among the most important reasons for the marketing of libraries in the social media. From the perspective of both groups, the Telegram is the most appropriate medium for the marketing of library services.

Results: To maintain their customers and their market position, libraries need to use more exciting tools such as social media for marketing. Library directors of this study emphasized on this fact and 79.1% of users expressed interest in receiving library information through social media.

Value: The findings of this study would help the library directors to better decide on the marketing of their library services in social media.

This study tested the double-edged desirability hypothesis to investigate whether a lack of reduction in desirability perceptions signified failure of a media literacy intervention to reduce the appeal of sexual portrayals or whether it instead represented an improved awareness of message-design techniques and, therefore, a successful intervention. Data from two media literacy curriculum evaluations, both pretest–posttest quasi-experiments with control groups (N1 = 922, M = 14.13, SD = 1.07; N2 = 1,098, M = 14.26, SD = 1.06) showed that the media literacy treatment in both studies eliminated the effect of desirability on participants’ attitudes, reduced the effect of message desirability on participants’ expectancies, and reduced the effect of message desirability on participants’ efficacy in one of the evaluations. The results supported the double-edged desirability hypothesis, which holds that media literacy education can diminish the influence of desirable but unrealistic sexual media messages on adolescents’ decision making concerning sex, regardless of whether it decreases their affinity for the messages. This approach appears to represent a more effective alternative to demonizing media messages teens find desirable.  相似文献

ABSTRACT

We applied the selection, optimization and compensation (SOC) model of successful aging to media use. Using a new self-report measure to assess selective and compensatory media use we illustrate the role of these media selection strategies in successful aging. In other words, we link compensatory and selective media use to different indicators of well-being among older nursing home residents and for a group of younger adults, which served as a comparison group. Selective media use was positively related to well-being for older, but not for younger adults, and compensatory media use was negatively related to well-being for both younger and older adults. In a second study, we replicated these findings with a sample of healthy older adults.  相似文献

Racism for Sale     
《资料收集管理》2013,38(3-4):85-95
Abstract

Publications sold via catalog by the American racist organizations Noontide Press, Sons of Liberty, and National Alliance are studied for subject and media type. Of 1941 titles sold by the groups, only twenty appear in all three catalogs, and 134 titles appear in two of the three catalogs. A majority of materials sell with Jews and Zionism, conspiracy theories, religion, race, and the Second World War, print is the predominant media type. This study points to the existence of a wide body of literature supporting modern racist opinion, and that particular organizations sell those items that support their own specific ideologies.  相似文献

Abstract

A method for the detection of egg white in binding media by immunofluorescence was tested on laboratory samples. Although the fluorescence was weak, results were found to be reproducible. Tests were then carried out on a series of ancient paintings and polychromies dating from the twelfth century onwards. Some of these samples, including certain blues from Van Eyck's Mystic Lamb, gave a positive response for egg white.  相似文献

A random-effects meta-analysis was undertaken to examine the effectiveness of the Door-in-the-Face (DITF) persuasive message strategy on compliance. Results indicate an overall significant effect of the DITF strategy on verbal compliance (k=78, r=.126), but an insignificant effect for behavioral compliance (k=39, r=.052). In terms of verbal compliance, the DITF strategy works significantly better than controls for different samples, across varied communication media, and for prosocial causes. Additionally, the DITF technique is more successful than controls for volunteering/research than other target behaviors (e.g., monetary donation). For both verbal and behavioral compliance outcomes, the toughness (measured as amount of baseline compliance) of the donation context negatively predicted the magnitude of the DITF effect. It is argued social responsibility theory best accounts for observed moderator factors.  相似文献

Summary

Reference services involve using technologies to teach users how to locate and use needed resources. The use of various media for the presentation of library instruction has gone on since the 1930s. A chronology of the use of film, slides, audio tape, videotape, television, and computer-assisted instruction is presented here with brief commentary on the positive and negative aspects of the use of each type of technology and some combinations of technologies for instruction.  相似文献

Abstract

In the 1990′s, school library media specialists must stress their expertise as teaching professionals in order to make informed decisions relating to the automation of library catalogs. The cognitive paradigm provides a user-centered perspective of the information retrieval process and confirms the problematic nature of the new technology for children. By applying the cognitive viewpoint to online information retrieval, school library media specialists can help guide system design and plan instructional programs that are developmentally appropriate for children.  相似文献

PurposeThis paper aims to examine whether Altmetric data can be used as an indicator for identifying predatory journals.Design/methodology/approachThis is an applied study which uses citation and Altmetrics methods. The study selected 21 predatory journals from the Beall's list and Kscien's list, as well as 18 non-predatory open access journals from the DOAJ's list, in the field of Library and Information Science. The Altmetric score for articles published in these journals was obtained from the Altmetric Explorer, a service provided by Altmetric.com. Web of Science was used to search for citation data of articles published in these journals.FindingsThe predatory journals almost have no presence in social media, with poor Altmetric score. In contrast, non-predatory open access journals have a high presence rate and Altmetric score. There is a significant positive correlation between the number of articles cited and the number of articles having Altmetric score among non-predatory open-access journals, but not among predatory journals. Poor Altmetric score may be viewed as a potential characteristic of predatory journals, but other indicators would also need to be considered to determine whether a journal is predatory.Originality/valueDistinct from the traditional research methods, this study combined citation analysis and Altmetrics analysis. By comparing the characteristics of predatory journals and non-predatory open access journals, the findings contribute to the identification of predatory journals.  相似文献

ABSTRACT

The free press performs essential democratic functions, but widespread negative attitudes toward the press threaten its legitimacy and effectiveness as a check on formal institutions. In order to combat these attitudes, media organizations must understand who holds them and why. A survey-based study of U.S. adults (N?=?2052) focuses on associations between perceptions of the news media industry as a threat to political performance and a range of politically oriented behaviors (i.e. news media exposure, political talk, political participation). Analyses reveal a series of non-monotonic relationships. Group differences between those who hold the most extreme views concerning news-media-as-threat are also explored. The opposing groups are distinct in some important ways (e.g. ideology, race), but are also found to be surprisingly similar (e.g. income, education, gender, news media exposure). The results suggest new strategies for maintaining and restoring confidence in media organizations.  相似文献

ABSTRACT

Venture capital funding is an increasingly common yet understudied management model in the rapidly changing market of news media. Drawing on scholarship in media management and entrepreneurship, this study applies a community ecology framework to analyze the relationship between venture capital funding and digital news media firms. In doing so, this work explores the interaction between legacy news media firms and new entrants as they struggle for scarce resources and seek to grow in the face of rapid change. A dataset tracking funding activity of legacy and startup news media firms is used to analyze resource allocation within the digital news media ecosystem. Results of the analyses provide insights for news media management by furthering understanding regarding venture capital funding models and the generative mechanisms that help drive growth. Specifically, findings highlight the importance of cross-sector engagement and the tension between firm age and position for growth in the digital news media ecosystem.  相似文献

Abstract

This conceptual paper is based on two propositions: 1.) An efficient flexibility management is a critical success factor for media companies. 2.) The concept of real options theory (ROT) aims at improving a company's flexibility management. As a consequence, it is analysed how ROT can contribute to the flexibility management in media companies. In this context, two research issues are investigated. First, it is shown that real options as substantiations of flexibility are of great importance for media companies: In doing so, it is outlined that options which focus on a company's fixed costs management and options which aim at improving a company's sales situation are of high relevance for all segments in the media industry. Contrarily, options which focus on a company's variable costs are only relevant for media companies engaged in the print segment. Second, it is illustrated how ROT can contribute to the reactive and proactive management of flexibility in media companies.  相似文献

ABSTRACT

This article will describe how merging service points in an academic library is an opportunity to improve customer service and utilize staffing resources more efficiently. Combining service points provides libraries with the ability to create a more positive library experience for patrons by minimizing the ping-pong effect for assistance. The Access Services Department at the University of North Texas Libraries was charged with management of the circulation and reference services offered at the service desk. Streamlined planning and modernized management of the desk and its impact on customer service in a changing library environment will be discussed.  相似文献

ABSTRACT

Recently, terms such as the “fourth industrial revolution”, or the “second machine age”, have been used both in the business press and by academics to describe the current era of technological development. Embedded in these catchphrases is an assumption about the role of technology in the economy, who it serves, and the outcomes it provides. Communication scholars have long studied how the economy and technology are independently framed in the media, but little work has focused on how these terms are framed together. Understanding how the media frames technology’s role in the economy, and how those frames change over time, is necessary to fully analyze the role of technology in today’s society. This paper conducts a comparative frame analysis of the business press in two recent periods heavily influenced by technological development: 1992–1998 and 2010–2016. Results of this frame analysis show that a positive Growth frame was the most popular frame used in both periods. Overall coverage of technology’s role in the economy has dropped significantly since 1992. The 2010–2016 period saw a notable drop in positive Market Disruption frames but an increase in positive Social Recomposition and Employment frames.  相似文献

Abstract

In the present study the amino acid analyses of five protein-containing media were first ascertained. Then several specimens, both antique and modern, whose identity was unknown to the analyst, were assayed. The application of quantitative amino acid assay was found to be a useful and accurate means of determining the nature of protein media when sufficient peptide (protein) material was present.  相似文献
