台湾大学接收改造中的“国界”与“省界”--基于《罗宗洛日记》(1945-1946)的观察

台北帝国大学的接收和改造,是抗战胜利后中国在台行使主权的重要组成部分。在此过程中,以罗宗洛为代表的教育部台湾区教育复员辅导委员会人士,除了处理中国人与日本人之间已然改变的主从关系,还需要面对新出现的外省人与本省人之间的关系,经历了从有"国界"、无"省界",到"省界"显、"国界"隐的潜变。大学接收中突出体现的是不分省籍的告别殖民地地位的急切期盼,接收后的大学改组则越来越彰显外省人士与本省人士具体利益诉求的差异,使接收初期合作无间的省籍关系出现裂隙,甚至影响到本已达成的国族认同。

“国界”视野下对文物回归方式的思考

文物的"国界"争执,萌生于早期国家之间的财富诱惑及掠夺,之后才上升到体面和文明,以及对人类共同文化遗产的珍视和尊重。人类可以通过对文物历史价值和历史意义认识的不断深化,以更理性方式,包括以法律、捐赠、资金购买等方法去抚平对文化遗产的争执,合理实现文物回归。

The Influence of forest certification on forest product trade

Forest certification is considered to be complementary to forest management policies and takes a significant effect on forest product trade. In recent decade, it has been followed with interest and approved by governments and forestry de-partments in the world. This paper analyzes the influence of forest certification on forest product trade in the world, including the interest in certification in exporting countries and importing countries, trade flow and business competition, and the demands for Certified Forest Products (CFPs) and also discusses the influence of forest certification on forest product trade in China.

Measuring Tourist’s Water Footprint in a Mountain Destination of Northwest Yunnan, China

Monitoring and minimizing tourist’s water consumption is essential for the sustainable development of mountain destinations in the world. However, available data and a generally accepted protocol on such measurement are still limited. This study uses water footprint accounting to quantify tourist’s water demand in the Liming valley, a World Heritage site and a rapidly growing tourism destination in Northwest Yunnan, China. Both the water for direct and indirect use is taken into account based on the consumptive behavior of the tourists in the valley. Data were collected through guesthouse monitoring and a tourist survey in the 2005 tourist season. The results indicate that an average tourist leaves behind a footprint of 5.2 m3 on local water resources per day. Food production and waste dilution are the two most important water consumption factors. The results also show tourists consume more water than the local residents on per capita basis. This suggests more commitment is necessary to cope with this stress by individual tourists. Management implications to make water use more sustainable in mountain destinations are derived from this study.

Earthquake-triggered landslides affecting a UNESCO Natural Site：the 2017 Jiuzhaigou Earthquake in the World National Park,China

On August 8^(th), 2017, an Ms 7.0 magnitude earthquake occurred in Jiuzhaigou County, northern Sichuan Province, China. The Jiuzhaigou Valley World National Park was the most affected area due to the epicentre being located in the scenic area of the park. Understanding the distribution characteristics of landslides triggered by earthquakes to help protect the natural heritage sites in Jiuzhaigou Valley remains a scientific challenge. In this study, a relatively complete inventory of the coseismic landslides triggered by the earthquake was compiled through the interpretation of high-resolution images combined with a field investigation. The results indicate thatcoseismic landslides not only are concentrated in Rize Gulley, Danzu Gully and Zezhawa Gully in the study area but also occur in the front part of Shuzheng Gully along the road network(from the entrance of Jiuzhaigou Valley to Heye Village). The landslides predominantly occur on the east-and southeastfacing slopes in the study area, which is a result of the integrated action of the valley direction and fault movement direction. The back-slope effect and the slope structure caused the difference in coseismic landslide distribution within the three gullies(Danzu Gully, Rize Gully, and Zezhawa Gully) near the inferred fault. In addition, the topographic position index was used to analyse the impact of microlandforms on earthquake-triggered landslides by considering the effect of the slope angle. The study results reveal a higher concentration of landslides in the slope position class of the middle slope(30°-50°) in Jiuzhaigou Valley. These findings can provide scientific guidance for the protection of natural heritage sites and post-disaster reconstruction in Jiuzhaigou Valley.

Outlining a stepwise,multi-parameter debris flow monitoring and warning system:an example of application in Aizi Valley,China

In recent years, the increasing frequency of debris flow demands enhanced effectiveness and efficiency of warning systems. Effective warning systems are essential not only from an economic point of view but are also considered as a frontline approach to alleviate hazards. Currently, the key issues are the imbalance between the limited lifespan of equipment, the relatively long period between the recurrences of such hazards, and the wide range of critical rainfall that trigger these disasters. This paper attempts to provide a stepwise multi-parameter debris flow warning system after taking into account the shortcomings observed in other warning systems. The whole system is divided into five stages. Differentwarning levels can be issued based on the critical rainfall thresholds. Monitoring starts when early warning is issued and it continues with debris flow near warning, triggering warning, movement warning and hazard warning stages. For early warning, historical archives of earthquake and drought are used to choose a debris flow-susceptible site for further monitoring. Secondly, weather forecasts provide an alert of possible near warning. Hazardous precipitation, model calculation and debris flow initiation tests, pore pressure sensors and water content sensors are combined to check the critical rainfall and to publically announce a triggering warning. In the final two stages, equipment such as rainfall gauges, flow stage sensors, vibration sensors, low sound sensors and infrasound meters are used to assess movement processes and issue hazardwarnings. In addition to these warnings, communitybased knowledge and information is also obtained and discussed in detail. The proposed stepwise, multiparameter debris flow monitoring and warning system has been applied in Aizi valley China which continuously monitors the debris flow activities.

Re–Os geochronology of the Cambrian stage-2 and-3 boundary in Zhijin County, Guizhou Province, China

The black shale series that formed in the Edi- acaran-Cambrian transition are important stratigraphic records of the co-evolution of the paleo-ocean, -climate, and -biology. In this study, we measured Re-Os isotopic compositions of the black shale in the Niutitang Formation from the Gezhongwu section in Zhijin, Guizhou Province. The samples had high Re and Os contents, with Re ranging from 21.27 to 312.78 ng/g and Os ranging from 0.455 to 7.789 ng/g. The Re-Os isotope isochron age of 522.9 ± 8.6 Ma implies deposition of the Niutitang black shale predated the Chengjiang Fauna, providing an age constraint for the expansion of oceanic anoxia in the study area. The initial ^187Os/^188Os ratio of 0.826 ± 0.026 indi- cates that enhanced continental weathering might have triggered the expansion of the oceanic anoxia.

Hepatitis elimination by 2030: Progress and challenges

Globally, over 300 million people are living with viral he-patitis with approximately 1.3 million deaths per year. In 2016, World Health Assembly adopted the Global Health Sector Strategy on viral hepatitis to eliminate hepatitis by 2030. Different World Health Organization member countries are working on hepatitis control strategies to achieve hepatitis elimination. So far, only 12 countries are on track to achieve hepatitis elimination targets. The aim of the study was to give an update about the progress and challenges to achieving hepatitis elimination by 2030. According to the latest data, 87% of infants had received the three doses of hepatitis B virus （HBV） vaccination in the frst year of their life and 46% of infants had received a timely birth dose of HBV vaccination.There is a strong need to improve blood and injection safety. Rates of hepatitis B and C diagnosis are very low and only 11% of hepatitis B and C cases are diagnosed. There is a dire need to speed up hepatitis diagnosis and find the missing millions of people living with viral hepatitis. Up to 2016, only 3 million hepatitis C cases have been treated. Pricing of hepatitis C virus drugs is also reduced in many countries. The major hurdle to ach-ieve hepatitis elimination is lack of finances to support hepatitis programs. None of the major global donors are committed to invest in the fght against hepatitis. It will be very diffcult for the low and middle-income countries to fund their hepatitis control program. Hepatitis elimination needs strong fnancial and political commitment, support from civil societies, and support from pharmaceutical and medical companies around the globe.

Measurement and Interpretation of Connectivity of Chinese Cities in World City Network,2010

This is an empirical paper that measures and interprets the position of Chinese cities in the world city network in 2010. Building on a specification of the world city network as a′interlocking network′in which business services firms play the crucial role in city network formation, information is gathered about the presence of global service firms in cities. This information is converted into data to provide the′service value′of a city for a firm′s provision of corporate services in a 526(cities)×175(firms) matrix. These data are then used as the input to the interlocking network model in order to measure cities′connectivity and its predominant geographical orientation. Here we focus on the position of some key Chinese cities in this regard, and discuss and interpret results in the context of the urban dimensions of the′opening up′of the Chinese economy.

A Landscape Pattern Analysis Method Based on Boundaries and Nodes:A Case Study in Upper Minjiang River,China

Traditionally,patch-based analysis at the landscape scale fragmentation has been used in the study of landscape ecology while the study of boundary and node has not been considered as much detail until recently.This study investigated the possibility of applying boundary-and node-based methods in landscape pattern analysis to the upper reaches of the Minjiang River in the southwestern China.Boundary-based and node-based landscape indices were selected to be used in analyzing changes in landscape patterns,and the results were compared with analysis using traditional pattern indices.We compared the responses of patch-area-based,boundary-length-based and node-number-based indices,and concluded that boundary-based and node-based indices are more sensitive to disturbance than patch-based indices with various patterns,and node-based indices are even more sensitive than boundary-based ones.Thus,the results suggest that boundary-based and node-based pattern analysis methods provide helpful supplementary information to traditional patch-based pattern analysis methods.The results about pattern dynamics of landscapes in the upper reaches of the Minjiang River based on boundaries and nodes showed that with human disturbance,the dominance of forest landscape was weakened by other landscape types;thus the landscape pattern of the study area became more homogeneous and the boundary network became more complex.These changes further augmented disturbance interfaces in the landscape and increased the possibilities of further landscape fragmentation.

Trend and Interannual Variability of Chinese Air Pollution since 2000 in Association with Socioeconomic Development: A Brief Overview

Abstract Chinese air pollution has increased in this century along with the rapid socioeconomic development and resulting anthropogenic emissions. While recent emission control measures have shown encouraging re sults and have reduced the levels of sulfur dioxide and primary aerosols, the concentrations of other air pollutants continue to grow, particularly secondary pollutants in cluding ozone and secondary aerosols. Meanwhile, a va riety of intentional and unintentional socioeconomic events have temporarily changed the pace, and even the signs, of growth of air pollution. These events include the short-term emission restrictions imposed during the Sino-African Summit, the Beijing Olympics and Para lympics, the Shanghai World Exposition （Shanghai Expo）, the Guangzhou Asian Olympics, and the Shenzhen Uni versiade, as well as the unintentional emission reductions associated with the recent economic recession and the annual Chinese New Year. This paper presents a brief overview of trends and temporary perturbations of Chi nese air pollution since 2000, summarizing studies on anthropogenic emission inventories, atmospheric meas urements, and inverse modeling. It concludes with rec ommendations for future research.

Avalanche Warning Service without Frontiers in the Karawanks along the Slovenian-Austrian Border

The avalanche warning service was established within the operational European territorial cooperation program Slovenia-Austria （SI-AT） 2007-2013 project ＂Natural Hazards without Frontiers＂. Four institutes, two from Austria and two from Slovenia, work together to publish an avalanche report during the winter season. The first regular season was the winter 2012/2013. The avalanche and the slab avalanche situation in the transnational area along the 160 km border between the south of Austria and north of Slovenia show major differences of avalanche building weather situations. Because of the nearby sea in the southwest of Slovenia, the prevailing weather situations for high precipitation are coming from southwest or southeast. Nevertheless sometimes a lot of fresh snow occurs at northerly weather situations, which is unusual for Slovenian Alps and is therefore poorly forecasted for this region. Austrian avalanche experts are facing the same problems at southerly weather situations. Hence, an exchange of experience, weather data as well as model information improves the avalanche warning on both sides of the Austrian-Slovenian border.

Sedimentary Environments, Geometry and Characteristics of the Sand Layers within the Basin of El Ma Labiod （Algero-Tunisian Borders）

The authors＇ work concerns the study of sedimentary environments, the geometry and the characteristics of the silicon-clastic deposits within the basin of EI Ma Labiod at the Algero-Tunisian confines. The sedimentological analysis has proved a Miocene age of the sediments with varied environments： marine, fluvial-deltaic and lake. The geological aspect of the sediment, in particular sandy, is of the movable type or very slightly consolidated. The size of the industrial sand layers can be very diverse, however to feed from the industrial consumers having a certain perenniality, our prospection was directed towards layers with very important reserves. It is about a sedimentary basin with dimensions exceeding very largely the conditions of operating for such projects, which are at least one to two million tons. With the exception of a thin quaternary soil horizon, the basin is almost of an exploitation with open sky. The mineralogical determination has revealed siliceous to extra-siliceous sands, which are absolutely usable in the industry of glass, foundry and also in other functions like the abrasives of sanding and the clothing industry of the sandpapers. Concerning the economic aspect, the materials are very close and this is why the area has known the installation of a glassmaking factory and a cement factory using at the same time the Maastrichtian limestone, the sandy material and the clays of the Western zone of the basin.

The International Research Group in Geophysics Europe Africa： A Laboratory without Borders in the Earth Science and Environment

It was in 1995 that, at the end of the international project IEEY （International Equatorial Electrojet Year）, African and European scientists decided to create the IRGGEA （International Group in Geophysics Europe Africa） in order to pursue the scientific work started during the IEEY project, The main objective of IRGGEA was to introduce new fields of research in Africa and built teams of African scientists recognized at an international level in these new fields. To reach this goal, we developed days after days methods to manage smoothly a large network of scientists from developed and developing countries. After a short introduction on the field of research developed in the IRGGEA, we present the organization of the work based on sharing practices and the results obtained in terms of scientific publications and socio-cultural aspects as the increase of the number of women and positions for students in their countries. Such an experience is easy to reproduce.

Fossil woods from the Upper Cretaceous to Paleocene of Heilongjang(Amur)River area of China and Russia

Fossil woods were collected from the Upper Cretaceous to Paleocene beds distributed around Heilong- jang （Amur） River area of China and Russia. A total of 43 specimens were collected from Baishantou, Long- gushan, and Yong＇ancun in Jiayin, China, and 85 specimens from Zeya-Bureya Basin lying southeast of Blagoveshchensk in Russia. Selected specimens were sectioned and studied anatomically. The source deposits of almost all identifiable specimens belong to the Upper Cretaceous （Campanian） Taipinglinchang Formation and the Paleocene Wuyun Formation in China, and the Paleocene Upper Tsagayan Formation in Russia. Al- though the results obtained are still far from complete, the taxonomic composition of the fossil woods show marked stratigraphic differences between the two horizons beyond the K/T boundary in China. There is also a strong similarity in wood flora between the Wuyun Formation of China and the Upper Tsagayan Formation of Russia. All identified specimens from the Taipinglinchang Formation are Xenoxylon latiporosum, This is one of the stratigraphically younger records of Xenoxylon, which is a conifer morphogenus of uncertain affinity most common in the Triassic to Early Cretaceous. Only one specimen with possible derivation from either the Wuyun or the Maastriehtian Furao Formation in China was identified as Taxodioxylon sp. The Wuyun Formation yielded both conifers and dicotyledonous woods. The conifers include Taxodioxylon sequoianum of the Taxodiaceae, and Protopiceoxylon amurense, which is attributable to the extant genera Keteleeria or Nothotsuga of the Pinaeeac, both are at present endemic to China. At least two morphotypes of dicotyledonous woods were recognized, with one identified as el. Hamamelidoxylon , and the other diffuse porous wood is characterized by numerous heterogeneous rays. From the Zeya-Buleya Basin of Russia, Taxodioxylon sequoianum and cf. Hamamelidoxylon sp. were identified from the Upper Tsagayan Formation. The similarity of wood composition in both Wuyun and Upper Tsagayan Formations support lithological as well as biostratigraphic correlations proposed for the two formations.

Exiles Turn Lemons Into Lemonade： Multiethnic Poets of the US Crossing Borders

This study critically examines selections from the political poetry of African American writer Amiri Baraka （Le Roi Jones） and Arab American writer Suheir Hammad and the path they have chosen for themselves as exiles reflected in their writing. Edward Said＇s theory of exile is employed to illuminate common areas of interests that link the two writers together as exiles. The study reveals their attitude toward various issues that impact both races, the African American and Arab American such as imperialism, colonization, and oppression. Their poetry underlines the impact of capitalism and racism on US society and other nations disempowered by imperialism.
