Biogeography Today and Tomorrow

The chairman of Moscow University's Department of Biogeography reviews the various approaches being used in biogeography: habitat studies, the species composition of flora and fauna, the regional approach, the ecological approach and the historical approach. He outlines future research problems of biogeographers: the elimination of natural infection foci of disease, the rehabilitation of expanding areas in tailings, slag heaps and other wasteland, the biological purification of water, the conservation of natural communities and the creation of more productive artificial communities.     

乐府古辞与古诗十九首关系考辨

“古诗”之数,不仅十九之限,余见《乐府诗集》所收“古辞”之中,相与援袭,而存在一个共同的模仿对象,即乐府民歌。《乐府诗集》中《西门行》、《艳歌行》、《长歌行》等,当与乐府民歌相去不远,其主题元素广泛影响文人“古诗”制作;《西门行》一首尤为十九首中多篇祖述,而十九首之《生年不满百》为其改写。即此改写的言辞整练、构篇变化与音乐脱离,显见乐府歌辞向文人“古诗”的过渡,体现了后者的共同特点。究之“古诗”之作,并非“作者”的个体“创作”,而是展转相袭的共鸣抒写。     

After Seattle: Free Trade and the WTO

After the debacle in Seattle at the WTO Ministerial meeting in 1999, when the member countries failed to launch a new round of multilateral trade negotiations, new challenges to both free trade and the WTO have acquired importance. The former can be met by confronting the conceptual confusions, unfounded fears and policy-design sloppiness that afflict many of the demands of the critics. The latter, however, require changes in the WTO's functioning. But a distinction must be made among three areas: trade negotiations, the secretariat's work, and the dispute settlement mechanism. Each requires a different treatment.
