海峡两岸长期的隔绝给历史研究造成了诸多障碍,这在中华民国史的研究中表现得格外明显.笔者在台北"国史馆"查阅档案时,偶然发现颜惠庆的人事档案,在他的档案登记表上赫然敲着"投共"两字,并附有部分港台报刊在颜惠庆"投共"和去世后对他的报道和评论.虽仅薄纸几张,但已能折射出1949年前与后,对于这位中国近代史上著名外交家截然不同的"盖棺论定". 相似文献

新闻要素在故事化过程中的变形 总被引：1，自引：0，他引：1
故事化新闻以其鲜明的个性和可读性在激烈的媒介竞争中脱颖而出。它突破了以往的新闻纯粹地追求信息传递的局限,转而注重受众的接受体验。这种转变不仅仅反映在价值取向上,而且在新闻要素上也有所体现。 相似文献

This article explores the contributions of one of the pioneers of ratings research, James W. Seiler, the founder of the American Research Bureau (ARB), the forerunner of Arbitron. Seiler and his small management team filled a small but productive window of time as the youthful ARB rode the crest of a giddy but short-lived success during the ‘50s and early ‘60s. The ARB was responsible for a number of leaps in product design-including popularizing the diary method, first for television and then radio, extending the number of weeks of measurement from one to four, measuring all U.S. T.V. markets at the same time (known as sweeps, which was to lead to first extended measurement of TV viewing beyond metropolitan areas), and using the first meter to capture audience viewing in real time (called Arbitron). It emerged as the key competitor against the Nielsen service in the battle to measure the local market for television until it withdrew from TV measurement in the ‘90s. Arbitron's success led it to monopolize the measurement of radio audiences, a position it currently holds. 相似文献

In 1941 Australian tabloid journalist Dorothy Gordon Jenner was caught up in the Japanese siege of Hong Kong and was incarcerated in the Stanley Internment Camp. During her internment Jenner kept a clandestine record of daily life written in pencil on Bronco brand toilet paper and kept hidden in the heels of her shoes. To date her fragmented diary and notes have defied analysis. This paper provides a reading of Jenner's personal wartime testimonio through the frame of tabloid journalism to expose how the tabloid genre—Jenner's stock-in-trade as a journalist before the war—became the framework for her personal testimony during World War II. By interpreting Jenner's private diary and notes as testimonio journalism this paper exposes the flow of the tabloid vernacular style of journalism between private and public discourses. 相似文献

AbstractAnalyses of pigments from palettes used by J.M.W. Turner (active c.1792–c.1850) by means of microscopy, microchemical analysis, thin-layer chromatography, energy-dispersive X-ray analysis, X-ray diffraction and Fourier transform infrared spectroscopy are given. The occurrence of pigments in Turner's dated oil paintings and watercolours is also given, arranged by five-year periods. These findings are discussed in the context of published analyses of pigments from the first half of the nineteenth century. Turner used cobalt blue, emerald green, viridian, orange vermilion, barium chromate, chrome yellow, chrome orange and chrome scarlet within a few years of their known dates of discovery. It has become clear that Turner was using, or at least experimenting with, practically all the pigments known to be available at that time. In a few cases, in the light of these results, ideas on the availability of pigments to English artists have been revised backwards to the first known date of manufacture. Turner also possessed and used a wide range of red and yellow organic pigments, but few organic greens. The dyestuff extracted from Rubia tinctorum L. madder on an aluminiumcontaining substrate can be distinguished from the same madder on different substrates by its strong pink fluorescence in both ultraviolet and green light. The other red organic pigments (a second madder, brasilwood and cochineal dyestuffs on a range of substrates containing aluminium, copper, iron, aluminium/copper and clays) show negligible fluorescence. The red organic pigments were used in oil medium as well as watercolour, the yellows only in watercolour medium. 相似文献
