Primary sclerosing cholangitis (PSC) is a chronic, progressive, cholestatic liver disease characterized by inflammation and fibrotic obliteration of the hepatic biliary tree. It is commonly associated with inflammatory bowel disease (IBD). A number of complications can occur which require special consideration, the most important of which is the development of cholangiocellular carcinoma (CCC). Unfortunately, no medical therapy is currently available for the underlying liver disease. Liver transplantation is an effective, life-extending option for patients with advanced PSC. Geographical variations between East and West include a second peak for age with a lower association with IBD in a .lapanese population and female predominance in a lone study from Turkey. The clinical and biochemical Mayo criteria may not be universally applicable, as different patients show variations regarding the initial presentation and natural course of the disease, Directing research towards explaining these geographical differences and understanding the pathogenesis of PSC is required in order to develop better therapies for this devastating disease. 展开更多

While the region of western Guangxi-southeastern Yunan, China, is known and considered prospective for manganese deposits, carrying out prospectivity mapping in this region is challenging due to the diversity of geological factors, the complexity of geological process and the asymmetry of geo-information. In this work, the manganese potential mapping for further exploration targeting is implemented via spatial analysis and modal-adaptive prospectivity modeling. On the basis of targeting criteria developed by the mineral system approach, the spatial analysis is leveraged to extract the predictor variables to identify features of the geological process. Specifically, a metallogenic field analysis approach is proposed to extract metallogenic information that quantifies the regional impacts of the synsedimentary faults and sedimentary basins. In the integration of the extracted predictor variables, a modal-adaptive prospectivity model is built, which allows to adapt different data availability and geological process. The resulting prospective areas of high potential not only correspond to the areas of known manganese deposits but also provide a number of favorable targets in the region for future mineral exploration. 展开更多

Plant biomarkers, such as hydrocarbon waxes, are frequently found in various sediments and could be adopted as paleovegetation and paleoclimate indicators. Nevertheless, scarce researches have focused on leaf waxes in higher plants of alpine region.Herein, hydrocarbon leaf wax components of Salix oritrepha, which flourish in Nianbaoyeze Mountains in eastern Tibetan Plateau were fully discussed. The n-alkane distribution in leaves ranges from n-C_(21) to nC_(29) with maxima at n-C_(25), which were entirely different with Salix taxa displayed in previous surveys in non-alpine regions. The unusual even carbon nalkenes from n-C_(22:1) to n-C_(30:1), which were thought to appear only in aquatic organisms, were firstly reported in an alpine plant. Additionally, iso-(2-methyl) alkanes, ranging from i-C_(23) to i-C_(29) with maxima at i-C_(25), which have been commonly reported in microorganisms, were also identified in an alpine plant for the first time. Unusual hydrocarbon distribution detected in Salix oritrepha leaf from Nianbaoyeze Mountains is most likely due to the extreme environment in such alpine region. 展开更多

The post-colonialism is a theory proposed by the eastern colonial academist Edward W. Said. With the understanding and the definition of post-colonialism, the paper is to analyze phenomena of the movie 2012 and Avatar from several aspects. Firstly, the "other" is the first angle to be talked about. In the Westerners' perspective, they are the center of the world, and they dominate the world. Their rules are the accepted rules, and people of different origin or different cultures are all called "other". Secondly, it is the degeneration of eastern culture. In the complex of the degeneration of the culture, the demonization of the under-developed nations, the dominant language of English in the communication with the people around, feminization of the characters in the movies, and the updated colonialism of the colonized countries are to be mentioned. 展开更多

By using tai-yu (min-nan-hua, Taiwan Residents local language) to stage William Shakespeare's Macbeth, Po-shen Lu produced an experimental performance in the southern part of Taiwan in 2003. When producing Antigone in 2001, Lu was challenged by his critics in three aspects: (1) the tradition of tai-yu theatre of Tainan Jen Theatre and that of Western plays, (2) audience reception in Taiwan, and (3) the advantages and disadvantages of integrating tai-yu with Western classic texts. In spite of these criticisms on his theatrical productions, Lu has continued helping Tainan Jen Theatre transform into a professional theatrical troupe since he became an artistic director in 2002. By analyzing how and why Lu staged his The Witch Sonata--Psalm of Macbeth in the socio-historical context of intercultural adaptation, I propose to re-revaluate Lu's artistic contribution to the theatrical development in the southern part of Taiwan. I would argue that Lu is not only challenging Taiwan Residents reading of Shakespeare but also exploring the possibilities of tai-yu's theatricality, in a view to bringing new life to Taiwan's intercultural theatre. 展开更多

Tropical montane cloud forest is one of the ecosystems with the highest biomass worldwide, representing an important carbon store. Globally its deforestation index is –1.1%, but in Mexico it is higher than –3%. Carbon estimates are scarce globally, particularly in Mexico. The objective of this study was to simulate future land-cover scenarios for the Sierra Madre Oriental in Mexico, by analyzing past forest cover changes. Another objective was to estimate stored carbon in the two study areas. These objectives involve the generation of information that could be useful inputs to anti-deforestation public policy such as the REDD+ strategy. Remote sensing was used to measure land cover change and estimate carbon stocks. Satellite images from 2015, 2000 and 1986 were used, and Dinamica EGO freeware generatedmodels of future projections. Between 1986 and 2015, 5171 ha of forest were converted to pasture. The annual deforestation rates were –1.5% for Tlanchinol and –1.3% for the San Bartolo Tutotepec sites. Distance to roads and marginalization were highly correlated with deforestation. By 2030, an estimated 3608 ha of forest in these sites will have been converted to pasture. Stored carbon was estimated at 16.35 Mg C ha-1 for the Tlanchinol site and 12.7 Mg C ha-1 for the San Bartolo site. In the Sierra Madre Oriental deforestation due to land cover change(–1.4%) is higher than levels reported worldwide. Besides having high values of stored carbon(14.5 Mg C ha-1), these forests have high biodiversity. The models' outputs show that the deforestation process will continue if action is not taken to avoid the expansion of livestock pasturing. This can be done by paying incentives for forest conservation to the owners of the land. The results suggest that REDD+ is currently the most viable strategy for reducing deforestation rates in tropical montane cloud forests in Sierra Madre Oriental. 展开更多

Using the U.S. National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis data at 1°× 1° o resolution, analysis is performed on a persistent heavy rainfall event with two rain bands to the south of the Yangtze River during 17-22 June 2005. The northern rain band was related to the atmospheric mass adjustment of cold front precipitation and the associated ageostrophic feature to the rear right of subtropical westerly jets, while the southern counterpart formed under the joint influence of easterly/westerly jets and the South Asian high (SAH). The ageostrophic wind field to the rear right of the easterly jet center gives rise to an anti-circulation that favors the genesis of the southern belt. The feature ofdu/dt 〈0 around the SAH ridge line and to the rear right of the easterly jet streak results in a strong v - vg〈O field in the vicinity of the rain region as well as to its south. When westerly jets move southward, an intense v Vg〉0 feature appears to the north of the rain region, i.e., behind the center of the westerly jets. The associated mass adjustment leads to vigorous divergence over the rain region, which is responsible for the strong precipitation from the warm sector of the front. Also, a θe front at the middle level of the southern rain band and the cold front favor the release of instable energy to enhance the rainstorm. The southern and northern fronts approach each other and the two rain belts merge into one. 展开更多

In order to better understand the relative importance of hydrologic variation and anthropogenic disturbance and their complex interactions within the trace elemental geochemical cycle, water samples were collected monthly over 1 year in the Min River, eastern Tibetan Plateau, and analyzed for trace element composition. The dissolved trace elements exhibited different relationships with increasing discharge compared with major elements.The elements analyzed can be divided into three groups according to their behavior in response to changing discharge:(1) elements that showed weak positive correlation with discharge, e.g. Cu, V, and Ba;(2) elements that exhibited weak negative correlation with discharge,including Rb, Sr, Pb, Sb, Zn, Cr, Cd, and U; and(3) elements that displayed no significant correlation with variation in discharge, e.g. Ti, Fe, Co, Ni, and As. Cu was strongly affected by anthropogenic activities and flushed into the river with increasing discharge. Ba has a strong solubility in the terrestrial environment, dissolved quickly,and was released into the river. The positive relationship between V concentration and discharge may be attributed to secondary reactions, such as precipitation and adsorption on oxides and aluminosilicate clays. Conservative behavior had an impact on the geochemical behavior of Sr and Rb across hydrologic variation. Pb, Zn, Sb, Cd, and Cr underwent a mild dilution effect connected with anthropogenic activities. The chemostatic behavior of U was regulated by carbonate dissolution and biological uptake.In addition, higher temperatures enhanced biotic activities,affecting the concentrations of Fe and Ni. The relationship between power law slopes and coefficient of variation for discharge and solute concentration suggests that concentrations of trace elements vary significantly with increasing discharge compared with major elements. Silicate mineral weathering had less effect on the fluvial solutes with increasing discharge. Mining activity may exert an additional control on concentration–discharge dynamics of anthropogenic trace elements. 展开更多

In order to understand the role of East Asian subtropical westerly jet (EASWJ) in forecasting summer precipitation in East China,interseasonal pentad characteristics of the EASWJ and their relation to summer precipitation in East China are analyzed with the daily reanalysis data provided by National Centers for Environmental Prediction (NCEP,USA) and daily precipitation data from 714 Chinese meteorological stations during the period 1960-2009.In addition,the daily evolution of the EASWJ and objective quantification of the EASWJ are investigated for the Meiyu season over the middle and lower reaches of the Yangtze River valley.It is found that the EASWJ and summer precipitation bands in East China move simultaneously.Especially,the stationary state and northward shift of the EASWJ are closely associated with the beginning,ending and stabilization of the annually first raining season in South China and Meiyu over these reaches.Analysis on the characteristics of the EASWJ in typical (atypical) Meiyu years over these reaches shows that the EASWJ swings steadily around its climatological position in meridional orientation (with large amplitude).Numerical experiments on an example in 2005 shows that indexes proposed in this study can depict the EASWJ well and should be valuable for application in the operation. 展开更多

This article explains how modern European travelers, particularly European women adventurers, described East Asia. Travel writings that are expected to be truthful are not free from travelers' own personal, cultural, social, and political experiences and perceptions. At the turn of the 19th century, Europe was dominated by colonial discourse based on Western-centered textualized or imaginary knowledge of "the Orient''1. The imaginary texts affected European travelers. In turn, their travel writings helped substantiate and reinforce the texts. European women travelers, who were in a relatively disadvantageous situation at home, enjoyed going beyond the sexual boundaries imposed on them at home by using their assumed racial superiority in the Orient. However, their marginal position in Western society helped them ponder their own understanding of other peoples and cultures, of themselves, and of their home societies. This article traces not only the surface discourse of travelogues on East Asia, particularly on Korea, but also travel writers' inner worlds, focusing on differences between men and women. 展开更多

This paper considers a theory and practices of Japanese manabi (学) as an alternative concept of learning in the era of post-globalization. Although the term manabi is widely used as the translation of learning and Lernen in the field of pedagogy and in Japanese schools, it is important to understand its meaning, since the meaning of manabi is a comprehensive concept that differs semantically from the words learning, Lernen, and Bildung in the Western words. Faced with the globalization in the 21st century, there has been a tendency to promote educational reform and curriculum policies that could be characterized as "learnification" in which "21st century skills," "competency-based learning," and "learner-centered education" are emphasized. While the Western idea of learning that highlights active self is attractive to change classroom practices from the transmission of knowledge to an innovative style of active, collaborative, communicative learning, and problem-solving, Japanese education sustains traditional values that derive from selflessness and nothingness in Eastern philosophy. 展开更多

Both mathematics and art consistently reflect the spirit of the age in which they arise. Consequently, the mathematics in China and in Korea during the Joseon Dynasty, in contrast to the deductive western mathematics, does not function on the basis of proving something deductively. Rather, the Chinese mathematics from this period was based upon making observations about problems by combining patterns with specific examples. In this paper, this author attempts to compare the differences in mathematics between the East and the West, and also to study the different perspectives in art between the East and the West, in order to identify the relationship between civilization, culture and the spirit of the age. This will explain the reason why the Western 'One Point Perspective' had spread in China and the Chosen Dynasty, yet could not be permanently established in these countries. 展开更多

The primary scientific goal of studying salt lakes is to better understand the formation of small continental- type hydrogeochemical systems. Many scientists have attributed the metamorphism of the chemical composition of salt lakes to the evaporative concentration of water. How- ever, the formation of soda water is inconsistent with this hypothesis. Thus, analyzing intrabasinal biochemical pro- cesses and water--rocks interactions during the evaporative concentration of water allows us to understand the major mechanisms of the formation and evolution of water com- positions. Therefore, the aim of this paper is to identify the key processes involved in the formation of the chemical composition of the water in Lake Doroninskoye. An analysis of the distribution of major components shows that Na+, HCO3-, CO32-, and C1- are dominant in this water. High concentrations of these elements are the result of evaporative water concentration. Calcium, magnesium, and potassium are not accumulated because the water is saturated in min- erals containing these elements. The main barrier to the growth of the sulfate content of water is sulfate reduction. This process also contributes to the additional reproduction of carbon dioxide, which reacts with the products of the hydrolysis of aluminosilicates OH- to form HCO3- and CO32-, thus further contributing to the natural processes of soda formation. 展开更多

This paper argues that there is no real nationalism in the Middle East and if is, then it is an instrumental. The historical process of the region which relates to nationalism has had three stages: (1) the European conquest that forced the indigenous people to battle both for freedom and confront a secular idea such as nationalism; (2) arbitrarily marked borders by the West disregarding ethnic religious and tribal lines and affinity; (3) the creation of Arab nation states with no solid infrastructure of shared national values. This perspective can help understand current political developments in light of the Arab spring upheavals, in Iraq, Syria and Libya. 展开更多

This study uses DEM (Digital Elevation Model) data and remote sensing maps of the study area in 1993, 1999, and 2009 to analyze the slope gradient change of land use patterns in Qiandongnan Prefecture, Guizhou province, China. The land use data were classified into five types, forest, farmland, grassland, water and built-up, the slope gradients were divided into four grades. Indices for analyzing land use features were defined by their proportions, transformation matrixes, land use degree and changes The results showed that all land use types can be found at every gradient. Generally, with the slope degree increased, the area of forest being augmented as well, while the area of the other land use types (farmland, grassland and build-up) declined. Moreover, a mass of farmland were shifted from other land use types from o° to 25°, while a quantity of forest were transformed from the other land use types on 〉 25° from 2993 to 2009. In terms of land use degree and changes, the area of farmland and buildup land use types decreased when slope degree increased. Finally, we calculated the five landscape pattern metrics: Patch Density (PD) value, Largest Patch Index (LPI), Shannon's Diversity Index (SHDI), Area-Weighted Mean Shape Index (AWMSI) and Contagion Index (CONTAG). The results of metricsanalysis showed that PD values, SHDI values and CONTA values had a similar variation trend, that is, they decreased when slope degree increased. There was no obvious variation trend on LPI value. 展开更多

Many conflicts are reported in small islands mainly in Eastern region of Indonesia and it is needed to conflict resolution in the forest sector. The research has been conducted on forest conflict in the small island of Yamdena. The aims of the research were: (1) to determine the customary rights of indigenous peoples to the forest area that was claimed as theirs according to the applicable rules and regulations; (2) to study the causes of conflict between indigenous peoples and the logging company; (3) to analyze the policy in the forest resources management on the customary land. This research is qualitative and uses a case study methodology. Data collection methods used include semi-structured interviews, participant observation and focus group discussion (FGD). The results showed that indigenous peoples whose livelihood is highly dependent on the forest were most threatened because of forest exploitation of their traditional land by the logging company. Handling of the conflict potential in the forest resources management in Yamdena island was approached through use of traditional laws, involving all the relevant parties to the conflict. The forest management either by indigenous peoples or the logging company is no longer focused on the timber harvesting but more on conservation aspects. 展开更多

The first decadal leading mode of East Asian summer rainfall(EASR) is characterized by rainfall anomalies along the East Asian subtropical rain belt. This study focuses on the second decadal leading mode(2DLM), accounting for 17.3% of rainfall decadal variance, as distinct from the other two neighboring modes of EAMR, based on the state-of-the-art in-situ rainfall data.This mode is characterized by a South-China-wet–HuaiheRiver-dry pattern, and is dominated by a quasi-30-yr period. Further analysis reveals the 2DLM corresponds to an enhanced lower-level monsoon jet, an eastward extension of the western North Pacific subtropical high, and a weakened East Asian upper-level westerly jet flow. The Tibetan Plateau surface temperature and Pacific Decadal Oscillation(PDO) are closely linked with the 2DLM. The regressed SST pattern indicates the PDO-like pattern of sea surface temperature anomalies may have a teleconnection relationship with the 2DLM of EASR. 展开更多
