Hiroshima and Nagasaki in Japanese guidebooks

This study investigates the presentations of Hiroshima and Nagasaki as postwar tourism destinations in a selection of Japanese-language guidebooks. Comparison is made between commonly voiced criticisms of Japanese attitudes toward the two atom-bombed sites and the tourism activities suggested by the publications themselves. An expected presentation emphasizing Japanese suffering as a result of the atom bombs is not found in the guides, but neither is an openness to discussion of the war. The conclusions reached find Hiroshima standing as emblematic of the rebuilding nation as a whole, while Nagasaki remains largely outside of the social and cultural dynamics of postwar Japan.

Contractual Practice and Land Conflicts: The ‘Plant & Share’ Arrangement in Côte d'Ivoire

This paper tackles the broad issue of agrarian contracts, property rights and conflicts in the context of rural Côte d'Ivoire. Since the beginning of the 2000s, a new type of contractual arrangement has been developing rapidly: the ‘Plant & Share’ contract. Through such a contract, a landowner provides the land to a farmer who develops a perennial tree crop plantation; when production starts, the plantation, the plantation and the land, or the product is shared. The aim of the paper is to discuss the conflictive features of the arrangement. I argue that this contract, in spite of its potential for tensions and conflicts, constitutes an alternative to the much more conflictive land sales that currently dominate extra‐familial land transfers in the country.     

贵州西部石漠化与土地保护

地处长江水系与珠江水系分水岭地带的贵州省西部,石漠化较严重。大多数石漠发生在正向岩溶地貌和落水洞、漏斗、峡谷陡坡上;在不易形成石漠的岩溶洼地、溶盆中,由于不合理工业取土诱发石漠化。岩溶石山上树木遭受毁灭以及陡坡地带盲目垦殖,加速了石漠化。在贵州容易形成石漠的自然背景下,违背自然的人文活动加剧石漠化发生和发展,导致山区土地资源逐渐枯竭。     

基于m序列的宽间隔跳频序列的生成

为了克服对偶法生成宽间隔跳频随机序列的缺点,基于m序列,提出非线性模d法,利用非连续抽头模型,生成宽间隔跳频随机序列.比较了对偶法生成的跳频序列和非线性模d法生成的跳频序列的自相关性能和互相关性能等.计算结果表明,非线性模d法是对偶法的明显改进,其生成序列的随机性、抗干扰性都有明显改善,且相关性能接近于最佳跳频序列的相关性能.
