为了促进我国医学期刊编辑、作者及审稿专家对图表著作权问题的重视,通过调查医学期刊对论文中图表的合理使用和授权许可使用规定的现状,发现医学期刊存在对图表的著作权意识较薄弱,稿约和著作权协议中相关规定和要求表述不完善及不规范等现象。提出了医学期刊出版单位应提倡和尊重图表原创性,要求作者使用他人已发表的图表必须获得著作权许可,明确图表二次使用的合法使用范围,从而提高著作权意识,促进期刊论文图表的著作权保护。 相似文献

[目的/意义]以数据新闻为阅读情境、信息图表为实验材料，使用眼动与行为实验和质性访谈方法研究读者对信息图表的阅读效果，探究读者的认知和视觉反应，为数据新闻的设计策略优化提供参考。[方法/过程]采用两个阶段的单因素设计实验。阶段一为眼动实验，考察被试对不同类型数据新闻信息图表的平均注视次数、注视点持续时间和主观满意度。阶段二为信息图表阅读效果的行为实验，探讨信息图表中不同数据展示形式对阅读效果的影响，因变量为被试的反应时和正确率。[结果/结论]数据新闻的阅读呈现"Z"型视觉轨迹；导语段是浏览的重点区域；分栏标题获得高关注度。研究还证实，柱状图更易于吸引读者的视觉注意，创造整体性印象，让读者更主动地进入信息加工过程；折线图吸引视觉注意的能力稍弱，但细节突出，读者的记忆效果最好；而饼图的认知加工消耗的认知资源最多，应当谨慎使用。 相似文献

Medical Subject Headings and medical terminology: an analysis of terminology used in hospital charts
Terminology used by health professionals in everyday written discourse was compared with terminology in a standardized medical vocabulary, the Medical Subject Headings (MeSH). Fifty written hospital charts were selected at random and analyzed by a computer program that identified MeSH terms in the charts. The charts were analyzed against two related MeSH vocabularies--one containing MeSH terms and one containing both MeSH terms and backwards cross-reference terms. When small words such as articles and prepositions were disregarded, approximately 50% of the words in a medical chart were found to be MeSH-related terminology. In addition, about 40% of MeSH-related words in the charts were either MeSH terms or backwards cross-reference terms. 相似文献

This study investigates the processes by which competition in the television news market might promote the presence of arousing characteristics in television news. A total of 3,024 news stories from six Dutch television news programs over the period 1990 to 2004 were investigated through content analysis. The findings of the study show overall increases in all 6 arousing characteristics. The findings also show that commercial newcomers included more arousing characteristics in their news stories than the public service broadcasters, that commercial newcomers developed a news format that featured more arousing characteristics, and that existing programs reacted to newcomers by increasing the amount of arousing characteristics in their news stories. 相似文献

Health professionals are collecting and charting data about the family history of their patients in order, to determine if a predisposition to heart, stroke, cancer and other debilitating conditions can be detected or alleviated through patient.education and preventive medicine. Family history-taking for the purposes of preventive medicine is introduced, along with a brief history of the field. The pedigree chart and the genogram are described and their use by health personnel is discussed. A brief search strategy on MEDLINE and a selected bibliography are presented to aid the health sciences librarian to find information on the family history, genograms or pedigree charts. 相似文献

Abstract The history of Serbian publishing is inextricably tied to Serbian and Yugoslav history in general. The author discusses publishing in the territory from the beginning, concentrating on the period 1990-1999. She deals with statistics, and basic themes and problems from this period. She then compares censorship in communist Yugoslavia to that in 1990-1999. Finally, the article lists leading Serbian publishers from this recent period and their profiles. 相似文献

This article analyzes the sales patterns of audio recordings in the Japanese popular music market using the Bass model and its restricted model. First, the results of this investigation show that the majority of recent hit music was sold in the early stage of the sales cycle, and that the timing of purchase has shifted toward the time of release during the period from 1980 to 2005. Second, audio recordings featuring debut artists and unpopular artists sold slowly, compared with the audio recordings featuring popular artists. Third, sales of audio recordings released by independent record companies have also become concentrated in the early stage. 相似文献

ABSTRACTThe information and knowledge society has resulted in the exponential growth of information and communication technologies (ICTs), thus creating a gap between those who use ICTs and those who do not; hence the emergence of the term “digital divide” in the 1990s. One of the milestones of South Africa’s National Development Plan, a policy that charts the country’s development up until 2030, is to ensure that high-speed broadband internet is universally available at competitive prices. Notwithstanding the importance of ICTs in public libraries, the provision of such is still taking place on a limited scale in South Africa. This article investigates the use of ICTs in public libraries in South Africa as a tool in bridging the digital divide. It also examines the inequalities in access and use and suggests ways in which ICTs may be used to reduce the digital divide. A qualitative research methodology was adopted. In order for public libraries to function as an important tool in bridging the digital divide, there is a need to standardize the provision of public library services with regard to the digital divide. 相似文献

International collaboration as measured by co-authorship relations on refereed papers grew linearly from 1990 to 2005 in terms of the number of papers, but exponentially in terms of the number of international addresses. This confirms Persson et al.'s [Persson, O., Glänzel, W., & Danell, R. (2004). Inflationary bibliometrics values: The role of scientific collaboration and the need for relative indicators in evaluative studies. Scientometrics, 60(3), 421–432] hypothesis of an inflation in international collaboration. Patterns in international collaboration in science can be considered as network effects, since there is no political institution mediating relationships at that level except for the initiatives of the European Commission. Science at the international level shares features with other complex adaptive systems whose order arises from the interactions of hundreds of agents pursuing self-interested strategies. During the period 2000–2005, the network of global collaborations appears to have reinforced the formation of a core group of fourteen most cooperative countries. This core group can be expected to use knowledge from the global network with great efficiency, since these countries have strong national systems. Countries at the periphery may be disadvantaged by the increased strength of the core. 相似文献

This article charts 2 parallel movements in the communications sectors of the United Kingdom and Europe: the ascendancy of marketization policies within both the European Union and its major member states and accelerating convergence of the computing, telecommunications, and audiovisual industries. The contradictory character of policy at the European level is examined against the background of assertive pressure from the corporate sector for liberalization of regulatory regimes. Using data primarily from the United Kingdom, the struggle for survival of the public communications sector and the consequential difficulties of communications and social exclusion faced by lower income consumers are examined. 相似文献

A survey of the circulation of books and journals at the Downstate Medical Center Library was conducted, based on cancelled circulation cards accumulated during a one-year period. Analysis of the results shows the frequency of use of various materials by several groups of borrowers and brings out important differences between circulation of books and that of journals. One of the results was the compilation of a list of most frequently used journals. The findings are graphically represented by several tables and charts. 相似文献
