Entrepreneurial, independent digital media sites arose in response to disruption in the journalism industry brought on by emerging technologies. This study explores this trend in Latin America from the perspective of audiences. Based on surveys of readers of entrepreneurial digital news sites in Guatemala and Nicaragua, this mixed-methods study offers a snapshot of who these readers are and what they are interested in. Results showed readers of the Guatemalan and Nicaraguan news sites valued equally quality journalism and innovation, but differed when it came to the importance they placed on the sites’ business models. This study also illuminated a new dimension of innovation, one from the readers’ perspective. While some respondents associated innovation with use of new technologies, in general readers defined innovation as unique (to the region) and alternative (to mainstream media) ways of doing journalism; their definition, unlike that of journalists, was not necessarily technologically driven.  相似文献

Citation averages, and Impact Factors (IFs) in particular, are sensitive to sample size. Here, we apply the Central Limit Theorem to IFs to understand their scale-dependent behavior. For a journal of n randomly selected papers from a population of all papers, we expect from the Theorem that its IF fluctuates around the population average μ, and spans a range of values proportional to σ/n, where σ2 is the variance of the population's citation distribution. The 1/n dependence has profound implications for IF rankings: The larger a journal, the narrower the range around μ where its IF lies. IF rankings therefore allocate an unfair advantage to smaller journals in the high IF ranks, and to larger journals in the low IF ranks. As a result, we expect a scale-dependent stratification of journals in IF rankings, whereby small journals occupy the top, middle, and bottom ranks; mid-sized journals occupy the middle ranks; and very large journals have IFs that asymptotically approach μ. We obtain qualitative and quantitative confirmation of these predictions by analyzing (i) the complete set of 166,498 IF & journal-size data pairs in the 1997–2016 Journal Citation Reports of Clarivate Analytics, (ii) the top-cited portion of 276,000 physics papers published in 2014–2015, and (iii) the citation distributions of an arbitrarily sampled list of physics journals. We conclude that the Central Limit Theorem is a good predictor of the IF range of actual journals, while sustained deviations from its predictions are a mark of true, non-random, citation impact. IF rankings are thus misleading unless one compares like-sized journals or adjusts for these effects. We propose the Φ index, a rescaled IF that accounts for size effects, and which can be readily generalized to account also for different citation practices across research fields. Our methodology applies to other citation averages that are used to compare research fields, university departments or countries in various types of rankings.  相似文献

金融创新与金融体制稳定性研究   总被引:1,自引:0,他引:1  
随着经济全球化、金融国际化的进一步深入,金融创新突飞猛进。金融创新的发展直接加强了金融机构之间、金融市场之间、金融机构和金融市场之间的密切联系,同时,在不同程度上影响了中央银行、商业银行、金融市场及金融监管的行为,削弱了金融体系抵御局部风险的能力,整个金融体系的稳定性也随之降低。并且,金融创新又更加推动了以金融业务国际化、金融市场国际化、资本流动国际化为主要表现的金融国际化趋势,致使局部的金融风险更易转化为全局性的金融风险,影响了金融体制的稳定性。  相似文献

A great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified.  相似文献
