Making news of value: exploiting dissonances in economic journalism     

Tomás Undurraga 《Journal of Cultural Economy》2017,10(6):510-523

This article explores the multiple modes of valuation that pervade newsmaking in economic journalism. It does so by exploring the different ways in which journalists at Valor Econômico, the leading economic newspaper in Brazil, compete and cooperate in the production of news. Valor is a paradigmatic case for discussing valuation practices in newsmaking since its institutional promise is to produce news of value. How, if at all, do Valor journalists embrace the promise of producing news that generates value? Elaborating on Stark’s (2009. The sense of dissonance. Accounts of worth in economic life. Princeton University Press) idea of dissonance, it is contended that different orders of worth collide and cooperate within Valor newsroom. Moreover, journalists engage in a variety of valuation practices through which these orders of worth are shaped, defined, and refined, reflecting different understandings of economy and society, and different conceptions of what journalism is good for. I argue that Valor’s direction intentionally fosters a plural space of value dissonance in order to improve the quality of news reporting. I emphasise, however, that these dissonances are only productive against a larger background of consonance about what actually there is to disagree about. The article is based on a seven-month ethnography of Valor’s newsroom in São Paulo between 2013 and 2015.  相似文献   

Sultans' Paradise: The Royal Necropolis of Shāla,Rabat     

Péter Tamás Nagy 《Al-Masaq: Islam & the Medieval Mediterranean》2014,26(2):132-146

The following study concerns Shāla, which was the necropolis of the Marīnid rulers from 683/1284 to 752/1351. The Islamic buildings on the site have rarely received scholarly attention, although these edifices – despite their delapidated condition – are among the most important constructed by the dynasty. One of my main aims is to re-establish the buildings' chronological sequence, using the written and archaeological evidence, including publications about the site written in Arabic, which have hardly been considered so far. I also address the meaning and aims behind structure erected for each founder, which, in my view, have been misinterpreted by previous scholarship. In summary, this article attempts to revise our knowledge about the site.  相似文献   

Analysis of a varnish applied by Nicéphore Niépce to make a print used for photographic purpose transparent     

Agns Lattuati-Derieux  Jean-Philippe Echard  Sylvie Thao-Heu  Bertrand Lavdrine 《Journal of Cultural Heritage》2010,11(4):1-481

Nicéphore Niépce carried out a lot of meticulous experiments that led him to the invention of photography. In particular, in the 1820s, he obtained heliographs by coating a substrate with a light-sensitive substance, which was then exposed to light under a paper print made translucent with the help of varnish. The objective of the work described here is to determine how Niépce made these paper prints transparent. Did he use his experimental knowledge on photosensitive resins, or did he apply commonly used recipes of his time to make paper transparent? To date, no studies have been carried out on the varnish used by Nicéphore Niépce and no previous research has undertaken analytical investigations on Nicéphore's prints, using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR-FTIR) and Gas Chromatography/Mass Spectrometry (GC/MS). In this paper, we identify the varnishes used by Nicéphore Niépce on four transparent prints, now belonging to the Nicéphore Niépce museum in Chalon-sur-Saône, France. The varnish he used was based on a diterpenic Pinaceae sp. resin (most probably colophony). The finding is supported by historical knowledge about varnishes.  相似文献

A comparison of the reverse and power punches in oriental martial arts   总被引：1，自引：0，他引：1  

Gulledge JK  Dapena J 《Journal of sports sciences》2008,26(2):189-196

In this study, we compared mechanical factors in the reverse and three-inch power punches. Twelve expert male martial artists stood on a force plate, and executed reverse and power punches against a padded target fixed to a wall-mounted force plate. The force plates measured horizontal forces, and subsequently impulses and body centre of mass velocity changes. The motions of four markers attached to the arm were also collected, and were used to compute the horizontal velocities of the knuckle and of the arm centre of mass. The power punch produced smaller velocities immediately before impact than the reverse punch for the whole-body centre of mass (0.14 vs. 0.31 m x s(-1)), for the arm centre of mass (2.86 vs. 4.68 m x s(-1)), and for the knuckle (4.09 vs. 6.43 m x s(-1)). The peak force exerted by the fist was much smaller in the power punch than in the reverse punch (790 vs. 1450 N). However, the linear impulse exerted by the fist during the first 0.20 s of contact was slightly larger in the power punch than in the reverse punch (43.2 vs. 37.7 N x s). The results indicate that the power punch is less potent than the reverse punch, but slightly more effective for throwing the opponent off balance.  相似文献   

Can Interactive Web-based CAD Tools Improve the Learning of Engineering Drawing? A Case Study     

Pablo Pando Cerra  Jesús M. Suárez González  Bernardo Busto Parra  Diana Rodríguez Ortiz  Pedro I. Álvarez Peñín 《Journal of Science Education and Technology》2014,23(3):398-411

Many current Web-based learning environments facilitate the theoretical teaching of a subject but this may not be sufficient for those disciplines that require a significant use of graphic mechanisms to resolve problems. This research study looks at the use of an environment that can help students learn engineering drawing with Web-based CAD tools, including a self-correction component. A comparative study of 121 students was carried out. The students were divided into two experimental groups using Web-based interactive CAD tools and into two control groups using traditional learning tools. A statistical analysis of all the samples was carried out in order to study student behavior during the research and the effectiveness of these self-study tools in the learning process. The results showed that a greater number of students in the experimental groups passed the test and improved their test scores. Therefore, the use Web-based graphic interactive tools to learn engineering drawing can be considered a significant improvement in the teaching of this kind of academic discipline.  相似文献
