农林科技期刊来稿中使用非法定面积计量单位“亩”的现象仍较为普遍 ,为执行科技期刊面积计量单位标准化 ,编辑须将“亩”换算成“ｈｍ2 ”或其他法定面积计量单位。本文在总结“亩”换算成“ｈｍ2 ”或其他法定面积计量单位过程中容易出现差错的基础上 ,提出了避免差错的常用方法及应注意的问题。 一、农林科技期刊中使用“亩”的基本情况 “亩”是我国 1992年 1月 1日起停止使用的非法定面积计量单位[1] 。由于“亩”为我国人民和广大农林科技工作者所惯用等多种原因 ,目前使用“亩”的现象仍然较为普遍。据统计 ,2 0 0 2年《新农… 相似文献

在农业类书稿的编辑加工中 ,经常要碰到“亩产××公斤”、“亩施××公斤肥料”之类的句子。“亩”属于应废除的计量单位 ,因此 ,编辑往往将“亩”换算成“平方米”( 1亩 =666 66…平方米 )或“公顷”( 1公顷 =1 5亩 )。这样换算后虽计量单位符合规定了 ,但却给农民增加了麻烦。由于长期形成的习惯 ,农民对于“亩” ,脑子中有一个具体的可比的概念 ,而对于“平方米”或“公顷”现在还比较陌生。基于这种情况 ,笔者认为 ,在现阶段 ,用“1 / 1 5公顷 ( 1亩 )”表示“亩产”、“亩施”等中的“亩”较好。这种表示方法有两个好处 :一是既符合国… 相似文献

美国心理学家阿希做过一个有趣的实验:“在甲卡片上画一条线段x。在乙卡片上画三条长短不一但差异甚微的线段a、b、c。其中b线段等于x。这时,如果有8个人故意说a等于x,那么第9个人虽然也看出b等于x,但因前人都说a等于x。于是他便怀疑自已了,也说a等于x。阿希把这种盲目地顺从别人判断的现象称之为“从众现象”。我国古人也曾多次指出“从众现象”之弊:夫市之无虎明矣,然而三人言而成虎”, 相似文献

长期以来,我国土地面积一直沿用“亩”(市亩)等市制计量单位,与国际上通用的土地面积单位不一致,换算又十分麻烦。由于土地面积计量单位的改革涉及面广,政策性强,情况比较复杂,国务院在1984年2月27日发布的《关于在我国统一实行法定计量单位的命令》中确定:“农田土地面积计量单位的改革,要在调查研究的基础上制订改革方案,另行公布。”后来,随着法定计量单位的全面推行,长度法定单位“米”和面积法定单位“平方米”以及它们的倍数单位得到广泛应用,现实国家版图、地区疆域使用平方公里,耕地面积、林地、草地面积使用公顷,建筑用地包括农村计算宅基地使用平方米,为改革市制土地面积计量单位创造了条件。 相似文献

ABSTRACT The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed. 相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire. 相似文献

ABSTRACT The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs. 相似文献

Some key questions for publishers in today’s market are: Could Amazon’s recent merger and acquisitions strategy create a disruptive or paradigm shifting business model in the publishing industry? Do their recent actions post mergers and acquisitions illustrate a predicable pattern of behaviour that publishers can strategize around? This paper will explore these questions and look at some of the possible reasons behind Amazon’s business practices and the possible consequences to publishers. 相似文献

ABSTRACTGerman authorities are expecting more than 1 million refugees by the end of 2015. These people come to Germany to seek protection and assistance and to build a new life, therefore it is important to welcome them and to assist them in their integration as soon as possible. This situation creates a versatile and perfectly fitting opportunity for cultural and educational programs, including libraries, which can play a vital role in this integration process. The key to integration is the knowledge of the German language, and the most important challenge now is to teach the necessary language skills to as many asylum-seekers as possible. 相似文献

Abstract Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services. 相似文献

SUMMARY The Nevada Constitution provides voters with the ability to propose new statutes, amendments to existing statutes, and amendments to the State constitution through the initiative petition process. Voters can also approve or disapprove of existing statutes through the referendum petition process. Both require the circulation of a petition to collect a minimum number of signatures before the Secretary of State will place the measures on the ballot for the general election. As with other topics of law, Nevada has a profound shortage of research resources on initiatives and referenda, but State law and government Web sites provide enough information to allow for significant research. 相似文献

SUMMARY This article is a case study of Ariel use at the University of Texas at Austin. The author divides the history of Ariel use into three distinct stages: resistance, full implementation, and enhanced. For each stage the advantages and disadvantages of using Ariel are discussed. The author concludes that using Ariel saves both money and staff time and permits faster delivery of documents than other methods. 相似文献

SUMMARY CISTI, the Canada Institute for Scientific and Technical Information, is one of the world's largest document delivery suppliers, and was among the first to be fully automated. The revolutionary Intel-liDoc system, developed during the years 1993 to 1995, provided for end-to-end automation of the document delivery process, which has enabled CISTI to improve its service and accommodate growth. From the beginning Ariel was, and remains, an integral part of IntelliDoc. This article describes how Ariel has been integrated into IntelliDoc and into CIS-TI's services, showing the benefits to CISTI and to its clients. 相似文献
