Native Seed Collection and Use in Arid Land Reclamation: A Low-Tech Approach

Loss of vegetation production in arid lands has been difficult to remediate and has signifi- cant economic impacts on human populations. Restoration efforts based on non-local materials and large-scale mechanization have not been capable of efficiently reversing the trend of environmental degradation. The use of traditional knowledge and simplified methods of seed harvesting, storing, marketing and soil preparation have proven that regeneration of native species and efficient land reclamation is possible in areas that have traditionally been considered degraded beyond redemption. This paper describes a method of land reclamation that combines tradition and simple mechanics that can be applied in all arid areas that face desertification. Because the work builds on cultural practices long used in non-industrialized societies, it is particularly adapted to rural areas. The methods described have the potential to open new low-tech economic opportunities to all segments of local non-urban populations while combating desertification and creating a more ecologically sound environment.     

浅析知识经济时代的高校会计模式

知识经济时代理想的高校会计目标观念应当是决策有用性与管理责任的有机结合,既注重决策有用性,又不轻视管理责任;假设将被系统化、集成化模式所替代.因而,事件驱动模式代替顺序化会计处理程序,事项会计取代价值会计.

Fuzzy goal programming for biodiesel production

ABSTRACT

The energy consumed around the world and especially in Morocco is dominated by oil products. The latter; whether in the global or the national context; are mainly due to diesel, whose climate impacts are well established, suggesting the search for a greener alternative. Despite its virtues, biodiesel is struggling to impose itself for purely economic reasons. Thus, in order to offer a sustainable solution, while keeping in mind the unpredictable fluctuations (price, demand …). This work proposes a generalization of fuzzy goal programming into fully fuzzy goal programming and a relative application, where the aim is to have a final product at a competitive price.

调查了鲁浙皖沪境内１０市、县１９９０～１９９６年的防震减灾宣传工作。据此从其组织管理、宣传内容、宣传形式和宣传对策等方面作统计和归纳,并分析了本地区防震减灾宣传工作的主要特点和基本架构。     

运用模拟生态系统评价果尔在稻田使用的安全性

在自行设计的稻田－鱼塘模拟生态系统中，以鲤鱼幼鱼和沼虾成虾为试验生物，对果尔在稻田使用的生态影响进行了模拟评价。结果表明，果尔在环境中消解很快，若按规定剂量在稻田使用，不会对邻近水域的鱼虾类生物产生危害，对稻田养鱼也是安全的。     

关于毛泽东邓小平江泽民论加强思想政治工作队伍建设的探讨

毛泽东、邓小平、江泽民高度重视思想政治工作,并且从多个角度对这个问题进行了论述。本文主要从思想政治工作队伍必须具备较高的政治理论素质和正确的工作态度、工作方法及工作原则等方面探讨了毛泽东邓小平江泽民关于加强思想政治工作队伍建设的有关理论,并且提出了毛泽东邓小平江泽民关于加强思想政治工作队伍建设的理论对做好大学生思想政治教育工作的启示。     

劳资关系的分配视角分析

从历史发展进程的角度分析了劳资关系及其变化问题,并重点探讨劳动与资本之间分配关系的动态变化．“资本雇佣劳动”这种制度安排有其历史发展过程中的“路径依赖”特征,各种不同经济与法律环境对其形成与存在提供基础,而今后经济发展的复杂化将对传统的劳资关系产生重要的影响．劳资之间分配关系是劳资关系中最为重要而根本性的体现,劳资关系的变迁对于其分配关系也将产生影响,使劳资之间的分配模式从传统的“以物质资本为中心”的分配模式向新型的“以人力资本为中心”的分配模式转化．     

Cultural Erosion and Biodiversity: Canoe-Making Knowledge in Pohnpei, Micronesia

Abstract:  Erosion of traditional knowledge and practice is a serious and accelerating problem, but quantitative work on traditional knowledge loss and its importance to biodiversity conservation is lacking. We investigated traditional knowledge of canoe making, a skill heavily dependent on plant biodiversity, on Pohnpei, Federated States of Micronesia, through a survey of 180 island residents. Our results showed that there has been an intergenerational erosion of canoe-making skills. Given current trends, the present generation of Pohnpeians may be the last to retain any knowledge of this traditional craft. We also identified several correlates of knowledge loss—including Western educational level and occupation—that highlight potential avenues for skill conservation via governments, traditional leadership, and schools. These institutions could intervene to emphasize traditional knowledge, which would reinforce institutional contexts in which traditional knowledge and practice is valued. The heightened awareness of the value of biodiversity that is linked to traditional knowledge is key to biological conservation on Pohnpei and can help support local conservation programs.     

Developing sustainable agricultural systems for small farmers in Latin America

The great majority of farmers in Latin America are peasants who still farm small plots of land, usually in marginal environments utilizing traditional and subsistence methods. The contribution of the 16 million peasant units to regional food security is however substantial. Research has shown that peasant systems, which mostly rely on local resources and complex cropping patterns, are reasonably productive despite their small land endowments and low use of external inputs. Moreover analysis of NGO-led agroecological initiatives show that traditional crop and animal systems can be adapted to increase productivity by biologically re-structuring peasant farms which in turn leads to optimization of key agroecosystem processes (nutrient cycling, organic matter accumulation, biological pest regulation, etc.) and efficient use of labour and local resources. Examples of such grassroots projects are herein described to show that agroecological approaches can offer opportunities to substantially increase food production while preserving the natural resource base and empowering rural communities.
