实现跨界书写的一种可能——重评董启章的《西西利亚》

香港文学自1949年始与内地文学分离,呈现出与母体别样的文学景观,而具有跨界理念的叙事形态正是形成两者差别的始端。董启章作为当代香港作家典型代表,以其深刻的笔力将跨界意识尽展在各个时期的叙事作品中,这种写法始于他的处女作短篇小说——《西西利亚》。文中的主题呈现、身份意识、叙事特点和语言表达四个层面均与香港本土的跨界意识相互勾连,这对其后期跨界书写范式的成熟意义深远,同时该文也成为香港文学跨界书写生成过程的一个重要节点。

Divergent growth trends and climatic response of Picea obovata along elevational gradient in Western Sayan mountains, Siberia

In mountain ecosystems,plants are sensitive to climate changes,and an entire range of species distribution can be observed in a small area.Therefore,mountains are of great interest for climate–growth relationship analysis.In this study,the Siberian spruce’s(Picea obovata Ledeb.)radial growth and its climatic response were investigated in the Western Sayan Mountains,near the SayanoShushenskoe Reservoir.Sampling was performed at three sites along an elevational gradient:at the lower border of the species range,in the middle,and at the treeline.Divergence of growth trends between individual trees was observed at each site,with microsite landscape-soil conditions as the most probable driver of this phenomenon.Cluster analysis of individual tree-ring width series based on inter-serial correlation was carried out,resulting in two sub-set chronologies being developed for each site.These chronologies appear to have substantial differences in their climatic responses,mainly during the cold season.This response was not constant due to regional climatic change and the local influence of the nearby Sayano-Shushenskoe Reservoir.The main response of spruce to growing season conditions has a typical elevational pattern expected in mountains:impact of temperature shifts with elevation from positive to negative,and impact of precipitation shifts in the opposite direction.Chronologies of trees,growing under more severe micro-conditions,are very sensitive to temperature during September–April and to precipitation during October–December,and they record both inter-annual and long-term climatic variation.Consequently,it would be interesting to test if they indicate the Siberian High anticyclone,which is the main driver of these climatic factors.

Analysis of a Turning Cold Wave in Northern Xinjiang in Winter

Based on analyzing the circulation development of 100 hPa, 500 hPa, lower streamline field and the change of physical vadables, the diagnostic analysis of a turning cold wave process in northern Xinjiang from Feb. 10 -13th 2009 was carried out. The results showed that abnormality of 100 hPa polar vortex taking on stable two waves, catastrophe of 500 hPa western Siberian trough, strong cold advection and water vapor transport from Middle Asia are chief reasons of the process.

Responses of Planetary Waves to Global Warming: Implications from CMIP3 4×CO_2 Experiments

The planetary wave response to global warm ing with single forcing of greenhouse gases （GHGs） is investigated in this study by using a total of 11 model results that anticipated CMIP3 4XCO2 experiments. It is shown that the amplitudes of the planetary wave fluxes over Siberia, the Eastern North Pacific, and the North Atlantic decrease by approximately -10% to -30% in the warming context. In particular, the vertical wave flux over the Eastern North Pacific significantly decreases by -28.6%. The weakening of the planetary waves is partly associated with the decreased land-sea thermal contrast, which may be caused by the radiation effect of CO2 and the different surface heat capacities of land and sea. The present work provides a clear understanding of the re sponses of planetary waves to GHGs forcing.

Middle Jurassic vertebrate assemblage of Berezovsk coal mine in western Siberia (Russia)

The Berezovsk coal mine in western Siberia has yielded the most diverse Middle Jurassic limnic and terrestrial vertebrate assemblage of Asia. The vertebrate remains were recovered by screen washing from floodplain deposits on top of a thick coal seam of the Bathonian Itat Formation. A total of 29 vertebrate taxa has been recorded so far,including hybodontiform sharks,acipenseriforms,palaeonisciforms,amiiforms,dipnoans,anurans,caudates,turtles,squamates,choristoderans,crocodyliforms,pterosaurs,dinosaurs,tritylodontids,and a diverse mammaliaform and mammalian assemblage( eleutherodontids,docodontans,? amphilestids,dryolestids,and zatherians). The caudates are among the oldest in the fossil record and the anurans represent the oldest Asian record of this group. Among the mammals,Anthracolestes is the oldest and most basal known member of Dryolestidae and so far the only record from Asia. The vertebrate assemblage from the Berezovsk coal mine is very similar to that from the British Forest Marble Formation( Bathonian) and suggests a limited provincialism in the Middle Jurassic Laurasian landmass.

Spanish Last Names in the Naples Periphery

The purpose of this study is to shed light on the southern part of Italy where Catalonians ruled. Great numbers of Spaniards, principally the Catalonians, headed to that country. This affected the language, and, in turn, the history of people＇s last names. At first, some of the Spanish last names were used as nicknames for Italians. The method 1 used to get the data from primary sources was from spending time in Italy for four consecutive summers and visiting towns in the Naples area while I collected surnames found on houses. The Catalonians came to rule Sardinia, and their language and subsequently Spanish were official on the island. The linguistic influence of Spanish does not stop with surnames. A list of Spanish and Basque surnames which is redolent of the history of southern Italy and Sicily is appended. The geolinguistics interest lies in the way that the study of language, both ordinary words and proper nouns, offers important clues to the lives and movements of people of ages past, reflects political and economic aspects and also explains the ethnic origin of people who live in Sicily and Italy today or are descendants of Italians who have been important immigrants in the Americas, in Australia, and indeed around the world.

MORPHOTECTONICS OF THE BASEMENT SURFACE OF THE WEST SIBERIAN BASIN WITHIN NADYM-TAZ INTERFLUVE

The map of reflecting horizon A, plotted on the basis of regional geophysical materials, yieldsinformation about the bottom topography of sedimentary cover of the West-Siberian Basin within Nadym-Taz interfluve. Through morphotectonic analysis about this surface, the authors are able tounderstand the distribution characteristics of the main topographic irregularities, with the blockstructure of the lower cover floors and underlying complexes as the focus.The largest irregularities are caused by the presence of three regional altitude steps, which show a regional tendency of basement being submerged in the north-north-east direction. Within these irregularities, the authors have distinguished some regions, which can be divided, based on the characteristics of morphostructural distribution, into two groups, i.e., areal (Nadym, Tol'ka, Urengoy)and belt (Tarko-Sale, Russko-Chasel'ka and Messoyakha). The first ones represent quasihomogeneous blocks, whose surfaces are complicated by irregular low-amplitude elevations and troughs and low-gradient zones with gradient values being up to 0.03, or they submerge stepwise, with the leveled areas being separated by zones with high gradients (0.07-0.15). The morphostructure of the other group of regions is characterized by the en-echelon distribution of contrastingly positive and negative elements with high values of slope gradients (higher than 0.1-0.2).
