【目的】 报告应用源文献挖掘方法从低复制比投稿中筛查出的抄袭论文的特点,并详细介绍这一筛查方法,为期刊编辑认识和筛查这类抄袭论文提供借鉴。【方法】 选择近3年《山东医药》的来稿中AMLC检测复制比<20%的2421篇论文,应用源文献挖掘方法,先常规检索所有论文的中、英文题名,进一步对有可疑指征的论文进行重点筛查。从各数据库中检出可疑源文献后,与投稿论文进行全文比对,查证是否存在抄袭。【结果】 共查证得到存在确凿证据的抄袭论文30篇,分别为抄袭他人9篇、抄袭团队10篇和自我抄袭11篇。其中19篇(63.3%)抄袭论文的源文献通过中、英文题名检出,11篇(36.7%)的源文献通过对可疑论文的重点筛查检出。【结论】 低复制比的投稿论文中仍存在多种类型的抄袭论文,查重后再进行抄袭筛查是必要的;应用源文献挖掘方法有助于检出雷同源文献进而查证抄袭。  相似文献

【目的】探讨不同结构形式题名的特点,呼吁国内科技期刊编辑人员关注和接纳短句式题名。【方法】以国际顶尖科技期刊Cell为参照,分析国内科技期刊过多使用短语式题名而忽视短句式题名的原因,从功能性和适用性两大方面比较短句式题名与短语式题名的差异,剖析短句式题名的独特优势。【结果】短句式题名与短语式题名表达论文内容的角度不同,短语式题名是对论文研究内容和范围的概括;短句式题名多采用陈述句,直接提炼出论文的研究结论,读者可从中获取更有价值的信息。一味地为追求简练而固守短语式题名,忽视短句式题名,不利于论文关键信息的充分表述。【结论】科技期刊应根据论文的性质和特点,以信息量最大化、有效化为原则接纳合适的短句式题名。  相似文献

The currency of selected versions of the MEDLINE database on CD-ROM and in online format was studied. The arrival of issues from 72 monthly journals and nine weekly titles during a 3-month period was monitored and their appearance in the various MEDLINE formats were recorded. Availability data for MEDLINE published by the National Library of Medicine were used as a baseline and subsequent distribution delays for the different MEDLINE formats were calculated. The study suggests a delay of approximately 2 weeks for indexing and mounting the MEDLINE file on to host computers for online access. A delay of 6-8 weeks was calculated for the MEDLINE data to be encoded on to compact disk, shipped and posted to the library customer. The currency of the MEDLINE database formats was compared with a weekly current-awareness service, CURRENT CONTENTS ON DISKETTE LIFE SCIENCES (CCOD). The majority of papers were indexed and distributed in CCOD within 10 weeks of publication date. Most papers appeared within 15 weeks in the online MEDLINE format and within 20 weeks in CD-ROM MEDLINE. The primary journal arrived at the library site within 5 weeks in most cases.  相似文献

Background  

Previous studies suggested increased cancer incidence and mortality in workers exposed to solvents and other chemicals in computer manufacturing jobs. Most previous studies were of small cohorts and findings were inconsistent. A lawsuit involving a large U.S. company produced a data file for analysis. This study sought to elucidate patterns of mortality in workers who were engaged manufacturing computers and related electronic components in the largest database available to date.  相似文献

A study to assess the association between the prevalence of hypospadias and maternal occupational exposure to potential endocrine-disrupting chemicals was carried out using data from the congenital anomaly register of the Office for National Statistics. The occupation of the mother is recorded in this register and to facilitate the assessment of maternal occupational exposure, a specific job-exposure matrix for potential endocrine-disrupting chemicals was developed. Seven categories of contaminants were evaluated (pesticides, polychlorinated organic compounds, phthalates, alkylphenolic compounds, bi-phenolic compounds, heavy metals and other substances). Maternal occupations were all coded using the 1980 version of Categories of Occupations. Three occupational hygienists assessed the likelihood of exposure (unlikely, possible, probable) to these seven substance groups for all 348 possible job titles independently. Almost 30% of the job titles were classified as exposed to at least one substance category (possible or probable), with approximately 16% of the job titles being probably exposed to at least one substance category. Some examples of occupations with probable exposure to potential endocrine-disrupting chemicals include: farm workers, electricians, workers in the plastics industry, painters, printers, hairdressers, dental practitioners, laboratory workers, textile workers and cleaners. It is recognized that there are a lot of limitations to the use of job-exposure matrices in general and with the matrix presented in this paper in particular. However, the matrix forms the basis on which further developments on occupational exposure assessment of potential endocrine-disrupting chemicals could be founded. In addition, the job-exposure matrix has identified areas where more exposure information is required. For example, exposure to potential endocrine-disrupting chemicals can occur in occupations such as hairdressing and workers in beauty salons, where the working population is more likely to be female and for which little data exist on levels of exposure.  相似文献

A database of benzene, toluene, and xylene measurements was compiled from an extensive literature review that contained information on several exposure determinants, including job type, operation, mechanism of release, process type, ventilation, temperature, distance from the source, quantity, and location. The database was used to develop statistical models for benzene, toluene, and xylene exposure as a function of operation and other workplace determinants. These models can be used to predict exposure levels for subjects enrolled in community-based case-control studies. This article presents the derived parameter estimates for specific operations and additional workplace exposure determinants and describes a number of statistical and data limitation issues that are inherent in determinants modeling of historical published data. [Supplementary materials are available for this article.
