利用Photoshop及W indows自带的Truetype造字程序制作医学专用的自造字。首先在Photoshop中录入两个相近的常用字,然后将其栅格化成图像。利用W indows自带的Truetype自造字程序,同时打开自造字的图片格式文件,将自造字图像拷贝并粘贴到Turetype自造字程序中。利用此造字方法得到的Truetype字可以同其他标准汉字一样在W ord程序中编辑与输出。 相似文献

汉字作为汉文化重要的承载者,有着深厚的文化底蕴和规律性可循,汉字本体研究作为汉语语言学的重要分支,对汉字理据性构字的掌握有助于我们认识并掌握对外汉语汉字教学的一般教学规律,对汉语作为第二语言教学具有指导作用。本文就汉字本身构字的理据性,以汉字本体研究对对外汉语教学的启示做简要的探讨。 相似文献

药用昆虫资源的开发利用 总被引：2，自引：0，他引：2
昆虫是动物界中种类和数量最多的一类生物,占已知动物种类的3/4～4/5,它们当中不少种类是可供人类直接利用的医药资源,也有一些是目前尚待开发的潜在医药资源。据文献记载,目前我国已知可供药用的昆虫超过300种,资源十分丰富。这些药用昆虫资源是人类的天然医药宝库,是一笔巨大的物质财富,很值得开发利用。 药用昆虫与其它资源昆虫最大的不同点,是在于 相似文献

道德是人类社会一个特殊的印记,它在潜移默化中改变和束缚人们的行动。千百年来,关于它形成的原因,人们众说纷纭、各执一词,一直没有定论。我认为道德是我们祖先在漫长而残酷的自然选择中进化出的一种有利于人类生存的特性,它由存在于我们身体中的某一DNA片段,即道德基因所控制。动物行为学告诉我们:动物,包括人类的祖先类人猿都不具有道德,它们可以随意地杀死自己的同类而不感到有罪。因此,我们可以初步断定,道德不是 相似文献

认知风格任何一种都有其优势和不足,在教学过程中,教师不仅要实施与学生认知风格相一致的教学风格,即匹配策略,而且,也要有意识地实施失配策略,促进学生的全面发展和各方面能力的提高.教师在教学中要有意识地促进匹配策略和有意失配策略的结合. 相似文献

在过去的一个多世纪,商品的个性标志一直是美国人钟爱的广告工具。各种各样被广告商作为传播体系的＂会说话的动物＂和＂会跳舞的产品＂已悄无声息地蔓延在美国的流行文化中。1982年,有人在做调查后发现,凡是商品特征明显的广告,在改变品牌偏好的能力上要比同行业其他品牌强。这一点表明社会正在接收商品个性标志这样的讯息。然而,尽管商品个性标志的运用在广告商和消费者中大受欢迎,却几乎被完全遗忘在广告和流行文化研究的角落。本文将从相关文学的角度解析什么是商品个性标志,以及其如何运用在现代广告业中,并与消费者进行交流。 相似文献

One of the reasons the proponents of expanded universal service have not made much headway is that they have not been able to provide a coherent justification for the major resource and policy commitments it requires. The lack of consensus on the very meaning of the term "universal service" has added to the confusion. This article argues that it is critically important to articulate a clear justification for universal service before we discuss what it should include and how it should be funded, the two main preoccupations of the current debate. It answers the "why" question by drawing on the literature on consumption norms and citizenship rights and thereby provides a cogent justification for universal service. A clear articulation of the rationale for universal service should reduce some of the confusion in the current debate and bring greater clarity to the ongoing debate on this important public policy issue. 相似文献

There is debate on whether the adoption of new medical technologies has been a contributing factor to rising health expenditures. This literature is critically reviewed and another approach is advocated. This alternative approach rests on the distinction between product and process innovations. It is argued that the relationship between innovations and health expenditures can be illuminated, for process innovations, by determining if they are used as substitutes. The empirical results provide no indication that alternative technologies for diagnosing diseases/conditions of the upper gastrointestinal tract have been utilised by Australian medical practitioners, operating on a fee-for-service basis, as substitutes. The study provides new empirical support for the view that medical innovations contribute to rising health expenditures. 相似文献

Literary fiction has seldom been seriously considered as a mode of science communication. Here, I review novels from the 19th century canon of English literature in which characters either have, or aspire to have, substantive professional scientific roles to see what insights they provide into the practice of science in the Victorian and Edwardian eras. They reflect the historical transition of science from an intellectual hobby to a paid occupation, but also reveal that while a career in science became possible for a wider range of people, it seldom allowed these new entrants to undertake fundamental scientific research. 相似文献

Fostering technological innovation is considered as an important element of policies towards sustainable development. In the past 10 years, evolutionary policy approaches have been increasingly advocated. For several reasons, they seem well equipped to underpin sustainable innovation policies. They focus on dynamics of change and their drivers, they allow for a substantive perspective on technologies beyond mere input-output relations, taking into account trajectories and different characteristics of innovation, and they are able to describe circumstances under which established technologies might persist even when they are to some extent inferior to their new competitors (lock-in). However, the policy effectiveness of evolutionary approaches in cases in which radical or systemic changes are involved is not yet proven. In this paper we assess the theoretical rationale, instrumental aspects and the coping with policy constraints of three evolutionary policy approaches which have also been used in empirical studies: strategic niche management, transition management and time strategies. Each approach has its strengths and specific problems and all three have to be further developed and tested out but they hold promise for contributing to non-incremental change with economic and environmental benefits, by shaping processes of variation, selection and retention, with the outcomes feeding back into policy. They may also be used in other areas in which innovation direction is important, for instance health care or food. 相似文献

Objectives, agreements and matching in science-industry collaborations: reassembling the pieces of the puzzle 总被引：1，自引：0，他引：1
Nicolas Carayol 《Research Policy》2003,32(6):887-908
Science-industry collaborations have been the subject of a considerable attention in the last few years. The paper argues that, however, the existing studies are still restricted to a partial view of the phenomenon. In this respect, our study departs from the specialised literature by taking into consideration, for a given set of heterogeneous collaborations, information from both the academics’ and the firms’ side, relative to their characteristics, their aims and the collaboration settings. To do so, we constructed a database of 46 collaborations from original data we collected, in several European countries and in the US, within the SESI-TSER project. The first outcome of our study is a typology of science-industry collaborations built on a formal procedure (a multi-correspondence analysis followed by an ascendant hierarchical classification) exhibiting five coherent types of collaborations that we describe precisely. Highlighting the crucial importance of research agendas, we thus propose a simple rationale for the matching process. The latter leads us to propose an “assortative” matching hypothesis generating two polar configurations which we test and confirm. Finally, we examine the policy implications of the findings. 相似文献
