生物世界是多种生物的世界,多种生物的共同存在为人类提供了赖以生存的物质家园。一个区域物种的多少及物种的稳定程度,关系到维持该地域的生态稳定,关系到人与自然的和谐并持续健康发展。其实保护生物多样性的实质就是保护人类自己。下面,我就有关保护生物多样性的几个问题简要谈一谈。一、生物多样性生物多样性是指地球上所有的生物(动物、植物、微生物)以及这些生物的自然生态综合体。我们通常把生物多样性 相似文献

生物教学作为高中阶段的重要学科,主要以研究生命现象和生命活动规律为主。在高中阶段开设生物教学,其最主要的目的在于为国家培养创新型人才。而高中阶段的生物教学主要的教学环节为生物实验。学生通过生物实验不但能提高生物实践能力,同时还能够提高生物的理论知识记忆,从而提升生物学习效率。本文通过分析生物实验对高中生物教学的实际意义,来制定适宜的教学策略,以此来培养学生的生物实验探究能力。 相似文献

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production. 相似文献

弗洛伊德坚持“性欲乃是人类取得的一切成就的源泉”，认为“本能的升华是最引人注目的文化发展的特征；正是由于升华，高级的心智活动、科学活动、艺术活动或思想活动才成为可能。”人们对此很有异议。其实，弗洛伊德是在对“性”的最广泛意义的理解基础上创建他的“动力心理学”的，他试图从他对人的个体心理理解的立场出发，来解释人类的全部历史、全部事件和社会生活的结构，并以此建立一整套关于人类精神生活规律的学说和理论。深入探寻弗洛伊德性学说的底蕴，澄清他的“性力”、“原欲”概念的内涵，真正领悟其“升华”思想的真谛，才有可能拓宽我们的视野，深化对复杂纷繁的人的精神世界的研究。 相似文献

在我国构建和谐社会的实践中,对于唯物辩证法对立统一学说的认识需要深化。我们长期以来坚持的"矛盾的斗争性是无条件的绝对的,矛盾的同一性是有条件的相对的。矛盾的斗争性的绝对性体现了物质运动的绝对性,矛盾同一性的相对性体现了物质静止的相对性"的认识值得反思。实践表明,矛盾的斗争性和同一性都既有绝对性的一面,又有相对性的一面。运动的绝对性和静止的相对性是与矛盾普遍性的绝对性和矛盾特殊性的相对性直接相联系的。我们必须完整科学地把握马克思主义经典作家关于对立统一学说的论述,深化矛盾斗争性和同一性关系和作用的认识。 相似文献

本文有感于汉语词汇学、传统训诂学和中国古典解释学研究的深层需要,尝试着提出了“词义的召唤性与训诂的创造性”的理论范畴。上篇论述词义的召唤性及其形成的根据与功能,下篇探讨训诂的创造性及其形成的根据与效应。从而强调：词义的召唤性,是词义的基本特性之一,它体现了人与词义、人与世界的关系;训诂的创造性,是训诂的基本特性之一,它反映了人与文化典籍、人与解释活动的关系。而词义的召唤性,又是训诂创造性的形成根据;训诂的创造性,又是词义召唤性的语用效应。二者互动共变。 相似文献

This paper discusses the current radical changes in the Australian education policy. Central to the argument is the claim that the radical restructuring of the public sector hastened the loss of the possibility of any critical evaluation of national policy.The paper argues that this shift has been forced on the Australian state by the objective conditions expressed in a new realignment of the dominant transnational capital with the subordinate domestic capital, and in the shifts in a global capacity for consumption. The argument is underpinned by the claim that a new, post-Fordist (or flexible specialization) regime of capital accumulation is at present replacing the Fordist regime of mass production and consumption.The paper further argues that in order to achieve the system-preferred changes in the Australian education policy, the Australian government introduced radical changes in the production rules of policy formation. This involved a narrowing of policy making context and, crucially, an exclusion of voices critical of the shift towards economic reductionism.This loss of a critical sensibility constitutes the central concern of this paper. To advance the argument, in Part One, the paper discusses the relationship between the Australian state and the post-Fordist objective conditions of capital accumulation. Part Two argues that the lack of intellectual tradition in Australian public life was at least partially responsible for the easy passage given to neoclassical economics1 perspective in becoming a dominant public policy paradigm. Part Three locates the role of education within the context of the European philosophical tradition. It provides the link between critical sensibility, the project of Western civilization (which clearly extends beyond the modern vs. postmodern dichotomy), and the role of public discourse. Finally, the paper argues that education policy needs to take the issue of critical sensibility seriously. For this reason, it needs to be informed by a desire to go beyond the mere technical fit between graduates and the workplace, and allow itself to be inspired by new ideas, and new ways of seeing.Parts One and Two of this Article appeared in INTERCHANGE, Vol. 26, #2, 1995. 相似文献

What Education do you Miss by Going to School? Children's 'Coming-to-Knowing' About Science and Their Environment 总被引：1，自引：0，他引：1

Starting from Whitehead's notions of education as "the art of the utilisation of knowledge" and his rationale for eradicating "the fatal disconnection of subjects which kills the vitality of the modern curriculum," the article explores how these ideas relate to the current political realities of primary education in the United Kingdom and elsewhere. This is exemplified through a focus on learning about one's environment and the consequent tension between direct perception through non-school activities and the teaching of ideas via the formal school curriculum. A resolution is proposed which involves considering the learner's perspective, and the implications for teachers in terms of 'letting pupils in' to the teachers' own learning and their awareness of a plurality of ways of knowing. 相似文献
