在模糊集合中,给定范围内元素对它的隶属关系不仅有“是”或“非”两种情况,更有中间过渡状态,用介于0和1之间的实数来表示隶属程度。刑法中的量刑情节具有模糊性,没有明确的外延,但却有着隶属度的不同。在量刑中引入模糊数学理论,利用隶属度函数将不同的量刑情节数值化,然后在量的基础上进行综合评估,有助于量刑的科学化。  相似文献

注重考试环节提高教学质量   总被引:1,自引:0,他引:1  
考试是教学的重要环节,不同的学科、不同的课程有不同的特点。命题应严格遵循全面考核,突出重点,理论联系实际,注重考查学生的实务操作能力这一原则。在试题内容上,应难易适度;在阅卷方式上,应根据题型的不同采用不同的判分标准;在应试技巧上,应教导学生要懂、吃透基础知识,学会总结典型题型。同时应加强学生考前模拟训练。  相似文献

Lophophora is a member of the Cactaceae family, which contains two species: Lophophora williamsii and L. diffusa. Lophophora williamsii is an illegal plant containing mescaline, a hallucinogenic alkaloid. In this study, a novel method based on a single nucleotide polymorphism (SNP) assay was developed for identifying L. williamsii; this assay reliably detects SNPs within chloroplast DNA (rbcL, matK, and trnL-trnF IGS) and was validated for identifying Lophophora and L. williamsii simultaneously. The chloroplast DNA sequences from four L. williamsii and three L. diffusa plants were obtained and compared using DNA sequence data from approximately 300 other Cactaceae species available in GenBank. From this sequence data, a total of seven SNPs were determined to be suitable for identifying L. williamsii. A multiplex assay was constructed using the ABI PRISM® SNaPshot™ Multiplex Kit (Applied Biosystems, Forster City, CA) to analyze species-specific SNPs. Using this multiplex assay, we clearly distinguished the Lophophora among 19 species in the Cactaceae family. Additionally, L. williamsii was distinguished from L. diffusa. These results suggest that the newly developed assay may help resolve crimes related to illegal distribution and use. This multiplex assay will be useful for the genetic identification of L. williamsii and can complement conventional methods of detecting mescaline.  相似文献

The idea of radically extending average human life expectancy is an ancient one, but for most of human history exceedingly utopian. There is now, however, a revival of that idea, with some scientists and others arguing that it is possible and desirable. But the main problem with most of the life extension enthusiasm is that it is based almost entirely on the desire of some individuals to make it happen. The social consequences of success of such a venture are, however, either ignored altogether or dismissed on the grounds that any problems can be dealt with. In the end, none of our present human and social problems would be helped by radically longer lives and no obvious social benefits have been advanced to support it.

Aging research may significantly lengthen human life spans in the foreseeable future. This paper argues that we do not need to wait until this happens to prepare for the dislocations that may result. Increased longevity over the past century has already raised urgent, unresolved issues of equity, social cohesion, and human dignity. These developments, and our past experiences in dealing with them, provide a basis for revisiting the basic questions raised by all attempts to extend human life: what does life mean, and why is it worth extending?  相似文献

Agroecology has played a key role in helping Cuba survive the crisis caused by the collapse of the socialist bloc in Europe and the tightening of the US trade embargo. Cuban peasants have been able to boost food production without scarce and expensive imported agricultural chemicals by first substituting more ecological inputs for the no longer available imports, and then by making a transition to more agroecologically integrated and diverse farming systems. This was possible not so much because appropriate alternatives were made available, but rather because of the Campesino-a-Campesino (CAC) social process methodology that the National Association of Small Farmers (ANAP) used to build a grassroots agroecology movement. This paper was produced in a ‘self-study’ process spearheaded by ANAP and La Via Campesina, the international agrarian movement of which ANAP is a member. In it we document and analyze the history of the Campesino-to-Campesino Agroecology Movement (MACAC), and the significantly increased contribution of peasants to national food production in Cuba that was brought about, at least in part, due to this movement. Our key findings are (i) the spread of agroecology was rapid and successful largely due to the social process methodology and social movement dynamics, (ii) farming practices evolved over time and contributed to significantly increased relative and absolute production by the peasant sector, and (iii) those practices resulted in additional benefits including resilience to climate change.  相似文献

作为近现代国家刑事诉讼中普遍认同的一项基本原则,控审分离有其丰富内涵,诉讼公正系其核心价值,而分权制衡、人权保障、程序主体性、诉讼经济理论以及相应的心理学原理构成其理论基础。  相似文献

债权具有相容性和平等性,不仅在同一标的物上可以同时并存数个债权,而且数个债权人对同一债务人先后发生数个普通债权时,其效力一律平等,不因其成立先后而有效力上的优劣,是为债权平等原则.债权平等原则是体现民法上的平等原则和债之相对性原则的一项重要具体原则,为债权与物权区分说的基本构成要素之一.但在现代民法上,由于债权物权化趋势、优先权制度的设立以及协调公平与效益的法律价值冲突等因素,债权平等性原则正在被打破.即便如此,债权平等原则在债法领域的基础地位并未发生根本改变.  相似文献

认清与"法轮功"邪教组织的斗争是一场捍卫党、捍卫社会主义制度的大是大非的严肃政治斗争,是争夺群众、争夺下一代、争夺思想阵地的斗争,所以对这场斗争决不能掉以轻心.贯彻教育部的"通知"精神,在开展"校园拒绝邪教"的活动中,教师要率先垂范,为人师表.  相似文献
