The Appellate Body Approach to the Applicability of Article XX GATT In the Light of China - Raw Materials: A Missed Opportunity?

This article attempts to analyse and investigate the implications of the approach to the applicability of Article XX GATT adopted in the recent China – Raw Materials. Using the decision on the non-availability of Article XX defences for violations of China’s WTO-plus commitments on export duties as a backdrop, it scrutinizes the more general, ‘systemic’ approach to the applicability of Article XX exceptions developed by theWTO dispute settlement bodies, and sheds light on the implications of such approach with respect to the relationship between GATT 1994 andWTO obligations arising from different instruments of theWTOAgreement, such as new members’ accession protocols. It also suggests that an exception to this general approach could be envisaged when the fundamental environmental goals protected under Article XX b) and g) are at stake.

Weishenme Zhongguo zai diyi ci shijie dazhan zhong juyou zhongyao zuoyong 为什么中国在第一次世界大战中具有重要作用 (Why China Played an Important Role in the First World War)

Aufbauend auf dem analytischen Tool des Totalen Krieges (vgl. den Artikel des Autors zu Controversy Total War in 1914-1918-Online) werden im vorliegenden Beitrag die Anstrengungen Chinas im Ersten Weltkrieg zu denjenigen anderer nicht europäischer Länder wie Australien, Südafrika oder Indien in Bezug gesetzt. Dabei wird das Ziel verfolgt, den globalen Charakter eines Konfliktes deutlich zu machen, der zurecht als erster Weltkrieg bezeichnet wird und in welchem China sicherlich eine weit bedeutsamere Rolle spielte, als es gemeinhin in der Historiographie dargestellt wird. Ursprünglich wurde der Beitrag als Antwort auf die Frage konzipiert, warum nicht nur China für eine Globalgeschichte des Ersten Weltkrieges von Bedeutung war. Im Verlauf der Übersetzung wurde der Titel dahingehend angepasst, dass stärker die Bedeutung von Chinas Rolle im Ersten Weltkrieg betont wurde.

Oral manifestations of HIV/AIDS in China: a review

PURPOSE: The purpose of this study is to review the Chinese-language medical and dental literature from 1982 to 2008 on oral manifestations (OMs) of patients with HIV/AIDS for introducing the spectrum of OMs of the patients in China. MATERIALS AND METHODS: All data were extracted from 18 references which had used diagnostic criteria for HIV/AIDS. Four of the references had used the EC-Clearinghouse classification for oral lesions in HIV infection. The feasible overall rate and 95% confidence interval (95%CI) of the data on OMs were calculated. RESULTS: Risk group analysis revealed that, of 203 patients, 64.3% were men and 35.7% were women (age range, 5 months to 64 years; mean age in three studies, 34.0, 34.3, and 36.1 years). Of these patients, 22.2% were infected by sexual contacts, 11.8% by intravenous drug use (IDU), 59.6% by blood or its products, 2.9% by mother to child transmission, and 3.4% were unclear. In 203 patients, oral candidiasis (OC) was the most common lesion (66%, 95%CI = 59.48-72.52%), followed by herpes simplex (HS) (22.2%, 95%CI = 16.48-27.92%), ulcerative stomatitis (14.8%, 95%CI = 9.92-19.68%), salivary gland disease (11.3%, 95%CI = 6.94-15.66%), oral hairy leukoplakia (OHL) (9.8%, 95%CI = 5.71-13.89%), necrotizing gingivitis (5.9%, 95%CI = 2.66-9.14%), Kaposi's sarcoma (2.9%, 95%CI = 0.59-5.21%), other malignant tumors (2.9%, 95%CI = 0.59-5.21%), and linear gingival erythema (2.0%, 95%CI = 0.07-3.93%). CONCLUSIONS: The spectrum of OMs reported from China is similar to that described in the international literature. Present data are useful to supplement international resources of HIV/AIDS research.

Tracing glacier wastage in the Northern Tien Shan (Kyrgyzstan/Central Asia) over the last 40 years

The status and dynamics of glaciers are crucial for agriculture in semiarid parts of Central Asia, since river flow is characterized by major runoff in spring and summer, supplied by glacier- and snowmelt. Ideally, this coincides with the critical period of water demand for irrigation. The present study shows a clear trend in glacier retreat between 1963 and 2000 in the Sokoluk watershed, a catchment of the Northern Tien Shan mountain range in Kyrgyzstan. The overall area loss of 28% observed for the period 1963–2000, and a clear acceleration of wastage since the 1980s, correlate with the results of previous studies in other regions of the Tien Shan as well as the Alps. In particular, glaciers smaller than 0.5 km2 have exhibited this phenomenon most starkly. While they registered a medium decrease of only 9.1% for 1963–1986, they lost 41.5% of their surface area between 1986 and 2000. Furthermore, a general increase in the minimum glacier elevation of 78 m has been observed over the last three decades. This corresponds to about one-third of the entire retreat of the minimum glacier elevation in the Northern Tien Shan since the Little Ice Age maximum.

Multi-locus microsatellite analysis supports the hypothesis of an autochthonous focus of Echinococcus multilocularis in northern Italy

Echinococcus multilocularis is characterised by a wide geographical distribution, encompassing three continents (North America, Asia and Europe) yet very low genetic variability is documented. Recently, this parasite has been detected in red foxes (Vulpes vulpes) circulating in an Alpine region of Italy, close to Austria. This finding raised the question as to whether an autochthonous cycle exists in Italy or whether the infected foxes originated from the neighbouring regions of Austria. Studies have shown that multi-locus microsatellite analysis can identify genomic regions carrying mutations that result in a local adaptation. We used a tandem repeated multi-locus microsatellite (EmsB) to evaluate the genetic differences amongst adult worms of E. multilocularis collected in Italy, worms from neighbouring Austria and from other European and extra-European countries. Fluorescent PCR was performed on a panel of E. multilocularis samples to assess intra-specific polymorphism. The analysis revealed four closed genotypes for Italian samples of E. multilocularis which were unique compared with the other 25 genotypes from Europe and the five genotypes from Alaska. An analysis in the Alpine watershed, comparing Italian adult worms with those from neighbouring areas in Austria, showed a unique cluster for Italian samples. This result supports the hypothesis of the presence of an autochthonous cycle of E. multilocularis in Italy. EmsB can be useful for 'tracking' the source of infection of this zoonotic parasite and developing appropriate measures for preventing or reducing the risk of human alveolar echinococcosis.

The Gender of Chinese Christianity: Evaluating a New Research Perspective

This paper will discuss how the gender perspective can be applied to the study of the Early Modern Jesuit China mission. I will show that the category of gender provides a promising research perspective on Sino-Western cultural exchange, for it brings to the forefront important aspects of social life in the “contact zone” of Chinese Christian communities. I will argue that through the intercultural contact initiated by the Jesuit China mission, gender roles started to shift slightly on both sides. On the one hand, the Jesuits adopted the Confucian ideal of the separation of the sexes (nannü zhi bie), building for example separate Churches for women, something unknown in Europe. On the other hand, Chinese Christians were urged to reconsider aspects of their traditional gender norms, when for instance some men left their concubines in order to become Christian. The paper will be divided in three parts. First, it will focus on the history of concepts and discuss what gender relations meant in the context of the Early Modern China mission. Then it will turn to the representation of female religiosity in Jesuit Annual Letters and show how the gender perspective can lead to a re-evaluation this source genre. Finally, it will reflect on how the gender perspective can give us fresh insights into well-known paradigms on Sino-Western relations, taking the accommodation paradigm as an example.

From Personal Network to Institution Building: The Lifanyuan and the Formalization of Manchu-Mongol Relations

The Qing emperors, who ruled over China from 1644-1911, managed to bring large parts of Inner Asia under their control and extended the territory of China to an unprecedented degree. This paper maintains that the political technique of patronage with its formalized language, its emphasis on gift exchange and expressions of courtesy is a useful concept for explaining the integration of Inner Asian confederations into the empire. By re-interpreting the obligations of gift exchange, the Qing transformed the network of personal relationships, which had to be reinforced and consolidated permanently into a system with clearly defined rules. In this process of formalization, the Lifanyuan, the Court for the Administration of the Outer Regions, played a key role. While in the early years of the dynasty, it was responsible for collecting and disseminating information concerning the various patronage relationships with Inner Asian leaders, over the course of the 17th and 18th centuries its efforts were directed at standardizing and streamlining the contacts between ethnic minorities and the state. Through the Lifanyuan, the rules and principles of patronage were maintained in a modified form even in the later part of the dynasty, when the Qing exercised control in the outer regions more directly. The paper provides an explanation for the longevity and cohesiveness of the multi-ethnic Qing empire. Based on recently published Manchu and Mongolian language archival material and the Maussian concept of gift exchange the study sheds new light on the changing self-conception of the Qing emperors.

The Rasikajy civilization in northeast Madagascar: a pre-European Chinese community?

Archaeological excavations in northern Madagascar during the first half of the 20th century have revealed the presence of a former prosperous civilisation known as the Rasikajy civilisation. Little is known about the origin of this civilisation and how and when they first arrived in Madagascar. The most striking evidence for the Rasikajy civilisation comes from excavations at a necropolis in Vohemar located along the northeast coast, where more than 600 tombs containing spectacular objects were unearthed in the 1940s (Vernier & Millot 1971). The findings in the tombs included, amongst others, Chinese ceramics, silver and gold jewellery, iron weapons, glassware, bronze mirrors and chlorite-schist objects (ibid.). The latter objects were produced from chlorite schist mined at quarries in northern and eastern Madagascar and there is evidence that jewellery and iron objects were also produced by the Rasikajy from locally available raw material. Chlorite-schist objects have not only been found in coastal sites in Madagascar, but also in the Comores and eastern Africa suggesting an active engagement of the Rasikajy in western Indian Ocean trade. Our re-evaluation of published literature on archaeological sites in northern Madagascar indicates that the majority of Chinese ceramics found in the tombs at Vohemar dates from the 15th and first half of the 16th century with some dating back to the 14th century or earlier. Our comparative analysis of burial objects at Vohemar shows that locally produced chlorite-schist tripod vessels exhibit remarkable resemblances to ancient Chinese bronze ritual tripod vessels. The objects encountered in the tombs and their positions with respect to the body indicate that the Rasikajy practiced burial rites similar to those practised in the past in China. Our re-evaluation of the literature suggests that communities with Chinese roots were present in northeastern Madagascar prior to the arrival of the first Europeans in 1500 and participated in the Indian Ocean trade network. The demise of the Rasikajy civilisation seems to have occurred in the second half of the 16th century when production of chlorite-schist objects ceased. It is still unclear why this occurred.

Acute Stroke: Present and Future of Catheter-Based Interventions

Acute ischemic stroke is a major cause of morbidity and mortality in industrialized nations. The sequel of stroke ranges from mild to severe disability and even death. Since the impairment may be permanent, the costs to society from work incapacity and the need for long-term care can be high. Additionally, the burden of suffering associated with the disease may have devastating effects on individuals and families.Following the occlusion of a cerebral vessel, the full extent of the infarction may not become clinically and radiologically apparent until days after. By then, the surrounding watershed zone, or penumbra, either survives or succumbs to necrosis over time. The natural history of this "tissue at risk" is determined by two factors: the collateralization from other vascular territories and the possible occurrence of spontaneous recanalization of the occluded vessel. The current treatment options for acute ischemic stroke are aiming at an early and sustained restoration of flow to the penumbra. The effect of the treatment is therefore time-dependent and the neurologic outcome is a function of the time span between onset of symptoms and recanalization therapy as well as of the recanalization rate associated with a specific treatment.This report summarizes the results of the major trials on catheter-based interventions, either using thrombolytic drugs or novel mechanical approaches being developed to treat patients with acute ischemic stroke.

Monitoring cerebral oxygenation during balloon occlusion with multichannel NIRS

We report on oxygenation changes noninvasively recorded by multichannel continuous-wave near infrared spectroscopy (CW-NIRS) during endovascular neuroradiologic interventions requiring temporary balloon occlusion of arteries supplying the cerebral circulation. Digital subtraction angiography (DSA) provides reference data on the site, timing, and effectiveness of the flow stagnation as well as on the amount and direction of collateral circulation. This setting allows us to relate CW-NIRS findings to brain specific perfusion changes. We focused our analysis on the transition from normal perfusion to vessel occlusion, i.e., before hypoxia becomes clinically apparent. The localization of the maximal response correlated either with the core (occlusion of the middle cerebral artery) or with the watershed areas (occlusion of the internal carotid artery) of the respective vascular territories. In one patient with clinically and angiographically confirmed insufficient collateral flow during carotid artery occlusion, the total hemoglobin concentration became significantly asymmetric, with decreased values in the ipsilateral watershed area and contralaterally increased values. Multichannel CW-NIRS monitoring might serve as an objective and early predictive marker of critical perfusion changes during interventions-to prevent hypoxic damage of the brain. It also might provide valuable human reference data on oxygenation changes as they typically occur during acute stroke.

UHP Metamorphism Documented in Ti-chondrodite- and Ti-clinohumite-bearing Serpentinized Ultramafic Rocks from Chinese Southwestern Tianshan

The southwestern Tianshan (China) metamorphic belt records high-pressure (HP) to ultrahigh-pressure (UHP) conditions corresponding to a cold oceanic subduction-zone setting. Serpentinites enclosing retrogressed eclogite and rodingite occur as lenses within metapelites in the UHP unit, which also hosts coesite-bearing eclogites. Based on the petrology and petrography of these serpentinites, five events are recognized: (1) formation of a wehrlite–harzburgite–dunite association in the mantle; (2) retrograde metamorphism and partial hydration during exhumation of the mantle rocks close to the seafloor; (3) oceanic metamorphism leading to the first serpentinization and rodingitization; (4) UHP metamorphism during subduction; (5) retrograde metamorphism during exhumation together with a second serpentinization. The peak metamorphic mineral assemblage of the serpentinized wehrlite comprises Ti-chondrodite + olivine + antigorite + chlorite + magnetite + brucite. A computed pseudosection for this serpentinized wehrlite shows that the Al content in antigorite is mostly sensititive to temperature but can also be used to constrain pressure. The average XAl = 0·204 ± 0·026 of antigorite (XAl = Al (a.p.f.u.)/8, where Al is in atoms per formula unit for a structural formula M48T34O85(OH)62, and M and T are octahedral and tetrahedral sites, respectively) included in Ti-chondrodite and average XAl = 0·203 ± 0·019 of antigorite in the matrix result in a well-constrained peak metamorphic temperature of 510–530°C. Peak pressures are less precisely constrained at 37 ± 7 kbar. The Tianshan serpentinites thus record UHP metamorphic conditions and represent the deepest subducted serpentinites discovered so far. The retrograde evolution occurs within the stability field of brucite + antigorite + olivine + chlorite and formation of Ti-clinohumite at the expense of Ti-chondrodite has been observed, suggesting isothermal decompression. The resulting P–T path is in excellent agreement with the metamorphic evolution of country rocks, indicating that the UHP unit in Tianshan was subducted and exhumed as a coherent block. To refine the metamorphic path of the ultramafic rocks, we have investigated the stability fields of Ti-chondrodite and Ti-clinohumite using piston-cylinder experiments. A total of 11 experiments were conducted at 25–55 kbar and 600–750°C in a F-free natural system. Combined with previous experiments and information from natural rocks we constructed a petrogenetic grid for the stability of Ti-chondrodite and Ti-clinohumite in F-free peridotite compositions. The formation of Ti-chondrodite in serpentinites requires a minimum pressure of about 26 kbar, whereas in Ti-rich systems it can form at considerably lower pressures. A key finding is that at UHP conditions, F-free Ti-chondrodite or Ti-clinohumite breaks down in the presence of orthopyroxene between 700 and 750°C, at temperatures that are significantly lower than those of the terminal breakdown reactions of these humite minerals. These breakdown reactions are an additional source of fluid during prograde subduction of serpentinites.
