The reliability and validity arouses a dispute on Internet-based CET (iB-CET) oral test in China, leading to the penetration into oral test contents in dialogue, description or comment, and question answering. Then, a probe into transformation from a spoken document into a textual document is touched on a conversion ratio of 72% adopted at the present time, AEM to be carried forward being a necessary hypothesis for Afterwards, this paper focuses on the pipeline in AEM with the content features and the language itself, which is established in two different models in marking for extraction and detection. Through experiments, this paper reveals the fact that an iB-CET oral test can be performed perfectly in the pipeline of spoken documents transformed into textual documents which can be automatically marked. Hence the design of the iB-CET oral test reaches its reliability and validity.展开更多

Different from the methods based on the file directory, this approach utilizes the consistency among the data on the disk. A feature pattern library is established based on different types of fries according to the internal constructions of text. Data on sectors will be classified automatically by data clustering and evaluating. When the conflict happens on data classification, the digestion will be initiated by adopting context pattern. Based on this approach, the paper achieved the data recovery system aiming at pattern matching of txt, word and PDF fries. Raw and formatting recovery tests proved that the system works well.展开更多

This is a serious meteorological disaster and extreme climatic event taking place under the climatic background of a warm phase of the Little Ice Age. In this paper, by means of historical literature records, the rainy and flooding situation and the weather characteristics of these years are reconstructed and the maps depicting areas of prolonged rain, flood and concomitant famine, insect pest, and pestilence are made. The results show that, in 1755, the middle and lower reaches of the Yellow River and the Yangtze River, and the Huaihe River Basin experienced a prolonged rainy season with multiple torrential rain events. The continuous rainy period exceeded 40 days in the Huang-Huai Region. An early Meiyu occurred, and the duration of the Meiyu period in the lower Yangtze River Basin was 43 days, the longest in the 18th century. Particularly in Nanjing the annual rainfall of 1755 was 1,378 mm, the highest record of the 18th century. The year of 1755 is characterized by lower temperature in summer, early frost in autumn, and heavy snowfall and freezing rain in winter. These characteristics are extremely similar to those of 1823 and 1954, two typical years of extreme rainfall. And all these three years with extreme precipitation axe corresponding to the minimum phase of the solar activity cycle.展开更多

Historical documentary records of climate are suitable for calibration on dating and the climatic implication of the proxy data in a climatological sense. A test calibration on correcting the Delingha tree ring precipitation series using Chinese historical documentary records shows that among the 44 extreme dry cases in 1401 1950 AD, 42 cases (or 95.5%) are believable. Thus the long series of Delingha rings-denoted precipitation is highly reliable. Another test to validate the monsoon intensity proxy data based on the Zhanjiang Huguangyan sediments using historical records indicates that the years of Lake Maar Ti content series-designated winter monsoon intensities are entirely opposite to historical documents- depicted years of harsh winters in 800-900 AD. As a result, serious doubt is raised about the climatic implication of this paleo-monsoon proxy series.展开更多

Unlike historical cinematic movements, these subgenres are the result of our techocentric culture and commercialism. In this respect these subgenres are less motivated by a collective ideology, but rather a cultural phenomenon resulting from increased access to popular culture, hypermedia devices, social media, and new marketing techniques. This paper investigates the displacement of traditional models of temporality through the metamorphosis of today's audiovisual culture, outlining the subject's embodiment of voyeurism and exhibitionism, ushering in a hyper-real era of self-myth making and consumption.展开更多

A robust body of literature documenting the health benefits of this eating pattern provides compelling reasons to change our dietary habits in ways that also benefit our environment, but we also need to have the right foods available and affordable to support this modest shift. This commentary discusses the gaps in current US dietary intakes compared to recommendations for meat and protein versus plant-based foods and the potential health benefits of shifting towards a more plant-based diet, focusing on the complex role of Mediterranean crops, such as tree nuts and olive oils, needed to support this shift.展开更多

Recognizing the emergent need of the resources on Hong Kong literature, the University Library System of the Chinese University of Hong Kong set up the Hong Kong Literature Database (the “Database”), which was the first Chinese literature database in the Internet in 2000. The paper will examine how the database is constructed using XML technology andometadata schema, The database also employs Unicode UTF-8 as the internal code. A mapping table for traditional and simplified Chinese characters was created based on Unihan and is used behind the scene so that a user can either input traditional or simplified Chinese characters and retrieval will give both traditional and simplified Chinese characters. Currently 65% of journals use OCR technology so that full-text searching is possible. The Chinese OCR technology will be examined in greater detail. Special features of the Database such as, page-by-page browse mode, position-highlight for full-page newspaper, linking Table-Of-Contents and book jackets from the Library catalogue, etc. are described. The paper will also bring out the problem of massive downloading and compare the state-of-the-art technology and their shortcomings. This paper shows how the Hong Kong Literature Database facilitates future collaboration and data exchange by using open standard, shareable structure and the latest technology.展开更多

Heat pumps are usually applied for the purposes of heating and cooling of energy efficient buildings where they have advantages in low-temperature systems, as it is well documented in the paper. The comparison of real thermodynamic processes with thermodynamically most favorable Camot's process is made. The results in the paper show that COP is diminishing with increasing of condensing temperature and also depends on real properties of working fluids. The impact of compressor efficiency for two real working media is also analyzed in the paper. There is significant diminishing of COP with diminishing of compressor efficiency. The intension of the paper is to help better understanding of this very effective and prosperous technology, and to encourage its development, production, and efficient application.展开更多

The research also aims to demonstrate through previously unknown and unheeded sources that there were not only those English travellers on their Grand Tour of the post-Restoration Bourbon Mezzogiorno (southern Italy) looking for an opportunity of comparing their own civilization (which was considered far superior) to a more fragile reality. There were also other British people who had identified, with a critical eye and spirit of observation, the existence of a Naples and a south Italy which did not merely represent the sum of stereotypes and fallacies handed down through the centuries, and thus refusing the obvious, predictable and false approach given by their own countrymen.展开更多

The analysis is based on field recordings and other ethnography collected by the author in 2006-2011. The music of the contemporary Arab-Anglican churches in Israel comprises different styles, which might be decoded as indices of group identity, and transmits different signifiers of belonging to diverse branches of the contemporary world Anglican tradition. A remarkable feature of this Christian community is the ongoing shift of subaltern identities when their most "Western" component--association with a particular sub-division of the Church--receives its musical expression by means of "local motif', that is, the tunes associated with regional repertories. The dynamics of ethno-religious identity of Arab-Anglicans in Israel manifests itself through several tendencies, such as ecumenical tendency and some other trends. Though the study is situated in the context of an interdisciplinary academic discourse, music is the main text addressed. "Reading" this music allowed the author to uncover tenets, trends, and interrelations within the communities under study.展开更多

It is concluded that statistics on natural hazards are questionable, in that changes in recording methods have artificially inflated the number of disasters and the seriousness of their impacts. Next, the paper examines the symbolic interpretation of disasters at various scales of analysis in terms of human cultures. It further applies this approach to the analysis of natural hazards using information technology methods such as GIS (Geographic Information Systems). Returning to the global scale, deficiencies and inequalities in the world disaster relief system are considered. Thereafter, the paper investigates how global economic imbalances are thrown into sharp relief by catastrophes, with examples from the record of past earthquakes, landslides and floods. Finally, it considers the prospects for a major change in the direction of world policy on disasters and concludes that this will only occur if the international financial system is forced to adjust to a "super-disaster" event, which could possibly be seismic, volcanic or nuclear in origin.展开更多
