在言语交际中,违反合作原则中某条或多条准则以后就会产生会话含义,相关词语的语用意义也就随之产生。因此,运用Grice的"合作原则"理论确定词语的语用意义是了解词语语用意义生成的一个重要途径。主要体现在对质准则、量准则、关联准则和方式准则的违反上。 相似文献

Dough rheological properties and noodle-making performance of non-waxy whole-wheat flour (WWF) with partial- or full-waxy (PW- or FW-) WWF substitution were studied. The substitution levels were 0, 250, 500, 750, and 1000 g/kg, respectively. FW-WWF reduced the peak viscosity and pasting temperature of WWF blends as its substitution level was increased due to its higher proportions of B-type starch granules and short amylopectin chains, while PW-WWF increased peak viscosity with the increasing substitution level because of its higher amylopectin content. As demonstrated by farinograph and rheometer measurements, FW-WWF interfered with gluten development because of the increased competition for water by arabinoxylans and amylopectin; however, PW-WWF enhanced dough strength due primarily to its increased protein content. Consequently, FW-WWF showed a detrimental effect on cooked noodle texture as the cooked noodle hardness was reduced by 50% at the 1000 g/kg substitution level. In contrast, PW-WWF enhanced noodle integrity and elasticity by increasing cooked noodle cohesiveness and resilience by 10.1% and 14.8%, respectively, at the 1000 g/kg substitution level. The results suggest that with waxy WWF substitution, the changes in starch composition, arabinoxylans, and protein content could modify the interactions among flour components and influence the quality characteristics of noodle products. 相似文献

Abstract This study examines price dynamics in roundwood exports from Russia to Finland, the largest international roundwood trade flow within Europe. The analysis covers six main timber assortments; sawlog and pulpwood dimensions of pine, spruce and birch. The study period, starting from the devaluation of the rouble in August 1998, was characterized by a drastic increase in the volumes of Russian roundwood imported into Finland, and a coinciding structural change in the timber assortment distribution of the Finnish roundwood imports. A basic hypothesis of economic theory, the law of one price, was tested by using quarterly time series and methods of cointegration analysis. According to the cointegration tests, the prices of Finnish and Russian spruce sawlogs have moved closely together. Furthermore, the changes in the prices of spruce sawlogs in the Finnish roundwood market are reflected in the Russian prices and not vice versa. Regarding other timber assortments, price co-movement and consequent market integration was not detected. 相似文献

SUMMARY Bwindi Impenetrable National Park and the Virunga Volcano region are the last remaining habitats of the highly endangered mountain gorilla (Gorilla beringei beringei). This conservation area, shared by Uganda, Rwanda and the Democratic Republic of Congo, also acts as a refuge for biodiversity and high endemism in the Albertine Rift of Central East Africa. This particular region has suffered from a number of years of civil strife, which have severely affected the management of these forests. This paper will explore the experiences of the International Gorilla Conservation Programme (IGCP) obtained throughout the development of regional processes that are working towards establishing a transboundary-protected area. The establishment of a regional framework and tools utilized are described. The costs and constraints incurred by the IGCP and the resulting positive impacts on conservation are also highlighted. 相似文献

Summary The tactics of war have profound impacts on tropical forest ecosystems, and modern weapons technologies have greatly increased their destructive potential. Some legal protection is afforded by customary international law, and the international community responded to the Vietnam War by adopting, inter alia, the 1977 Additional Protocol I to the Geneva Conventions and the 1976 Environmental Modification Convention, which prohibit “long-term” (or “long-lasting”), “widespread,” and “severe” environmental damage. Nevertheless, many regard these and other existing conventions as inadequate, especially as applied to internal conflicts. More recently, the International Union for the Conservation of Nature-World Conservation Union (IUCN) put forth a Draft Convention on the Prohibition of Hostile Military Activities in Internationally Protected Areas. This paper analyzes the IUCN Draft Convention-particularly issues of prior designation of protected areas, waiver of protection, and monitoring and enforcement-and compares it to other relevant area-based treaties, such as the 1954 Hague Convention for the Protection of Cultural Property and the 1972 World Heritage Convention. The paper also highlights other recent legal developments that may help prevent, remediate, or punish wartime damage to tropical forests, such as the nascent International Criminal Court; liability mechanisms for providing compensation for wartime damage; environmental guidelines for military, peacekeeping and humanitarian operations; import bans and trade embargoes; and a proposed no-fault remediation fund. 相似文献

The International Treaty on Plant Genetic Resources for Food and Agriculture is rapidly gathering sufficient ratifications to become international law. Once it enters into force, it will define the rules for access and benefit-sharing associated with most genetic resources of major food crops. This paper explains how the new Multilateral System established by the Treaty will work, and points out a number of ambiguities and problems in the text. Despite these shortcomings, the Treaty provides the international community of researchers, plant breeders, and farmers with an opportunity to foster cooperation and further the conservation and use of plant genetic resources. 相似文献
