Matjaž Mikoš 《Landslides》2018,15(8):1459-1482
Dissemination of research results is an important part of basic as well as applied research if not the most important one. A large part of research results is published in scientific literature, and since there are many forms of it, the question arises which form is the most visible and attractive to the world scientific community. The International Consortium on Landslides (ICL), based in Kyoto, Japan, is one of the leading institutions in the field of landslide research and landslide risk reduction. On behalf of ICL, Springer Nature has published the journal Landslides: Journal of the International Consortium on Landslides since 2004. It is a very successful scientific journal with regard to its scientometric parameters. Since January 2018, it has been a monthly journal published in full color in electronic as well as printed form. Another form of dissemination of the ICL scientific and professional activities are published books in the form of monographs and proceedings from triennial World Landslide Forums. This paper discusses the impact of 52 books with 3426 chapters taken from the field of landslide science and published by Springer Nature from 2005 to 2018 in the earth sciences category, using different scientometric parameters, such as Bookmetrix downloads and citations, Scopus citations, Scopus h-index, Google citations, and Google h-index. The analysis was performed on the book chapter level (using mainly citations as the main scientometric parameter) as well as on the book level (using book h-index and percentage of cited chapters). Out of the selected 52 titles, 22 were published on behalf of the ICL, with 1419 chapters. The differences among landslide-related books can be quite large; only a few chapters from analyzed book titles were found to be cited frequently compared to highly cited scientific journal articles. On average, the analyzed 3426 book chapters from 52 landslide-related books have been downloaded since publication over 53,000 times each; 1092 chapters (32%) received 2932 citations (2.68 citations per cited chapter and 0.86 citations per published chapter). The analysis shows that the books published on behalf of the ICL are, together with other landslide-related book titles, on the forefront in the Springer eBook collection Earth and Environmental Science (EES). The selected 52 landslide-related book titles are above the average metrics for the whole EES with regard to the total number of downloads per book, the total number of citations per book, and the total number of readers per book. The ICL-related books are getting more downloads but less readers and citations (so far) as the selected non-ICL-related books. A way in raising the visibility and impact of the ICL books on landslide research community would be to support their open access publication in the form of e-Books as much as possible, and inclusion of ICL books into Web of Science. 相似文献

31a《沉积学报》论文发表趋势:基于文献计量分析的结果与启示 总被引：1，自引：1，他引：0
基础研究和应用基础研究的创新成果主要以论文的形式发表在相关专业期刊上.《沉积学报》作为国内集中体现沉积学、沉积矿产和地球化学等方面创新性研究成果的载体,至今已创刊31年.本文利用数据库提供的文献详细信息,从文献计量分析的角度,透视《沉积学报》创刊31年来论文的发表趋势.基于对《沉积学报》刊载论文的数量、学科分类、研究地域、核心作者群、研究热点等指标的年际分布量化,分析了该刊所关注的研究内容与研究方向变革,探讨了国内从事该领域研究的组织机构分布与研究人员组成.结果表明,31年来,《沉积学报》的论文发表数量总体呈阶段性波动增长趋势;发文机构具有显著的地质、矿产、石油学科相关属性,地域相关性弱;沉积环境与沉积体系、碳酸盐岩、成岩作用、层序地层学、沉积盆地分析与模拟、沉积作用、油气储层沉积学、矿床沉积学、有机地球化学和元素同位素地球化学是《沉积学报》的热点和重点领域.基于引文分析(CSCD和SCIE引用)的结果表明,《沉积学报》刊载论文被引用频次和期刊影响因子不断提高,进一步说明了学界对《沉积学报》的关注程度不断加强.最主要资助来源为国家自然科学基金,占统计总量的40%.另外,由于新兴研究力量的兴起和研究者提高国际影响力的需求,导致该刊尚未形成核心作者群,这对《沉积学报》未来的发展提出了新的机遇与挑战. 相似文献

A geochemical cycle model is presented for the interaction between the atmosphere, hydrosphere, and regolith of Mars. It was developed to study how this interaction might have produced the present Martian environment from a primitive Martian environment much like that of the primitive Earth. The model is a simple system, consisting of an unweathered starting material (calcium-bearing and magnesium-bearing silicates), a CO2 atmosphere, an ocean of water in contact with both the atmosphere and the unweathering starting material, and both calcite and dolomite precipitates. Several interesting points arise from this model. A 1-bar CO2 atmosphere can be removed by carbonate precipitation alone in about half a billion years. This is roughly fifty times longer than earlier estimates, which were not based on time-varying models (Fanale et al., 1982; Carr, 1986; Pollack et al., 1987). One of the chief problems in Martian geology has been how to explain the large number and wide variety of surface features that were apparently formed by aqueous erosion. This longer atmospheric lifetime may be enough to explain the large number of channels seen on older Martian terrain. If the atmosphere started out with more than 1 bar of CO2, it would take correspondingly longer to remove it. If there should be no other means to remove CO2 from the atmosphere, this long time constant would indicate that the atmosphere could never have contained more than a few bars of CO2, or else there would still be remnants present today. The increase in alkalinity of the ocean as the atmosphere disappears, even without the effects of reduction in the amount of water available, indicates that evaporite deposits may have formed on Mars. If these deposits are still present, they may even yet contain some liquid water. 相似文献

Matja? Miko? 《Landslides》2011,8(4):541-551
The international journal Landslides (ISSN 1612-510X), launched in 2004 and published by Springer Verlag, soon gained international recognition as the only specialized
scientific journal in the world dedicated to different aspects of landslides, and as one of the leading world journals in
the field of geological engineering. After 7 years, seven published volumes with 28 issues and 290 published papers on 2,794
pages, there is time to make a comparison with other related journals that also cover the field of landslide risk mitigation.
The critical review of these seven publishing years was done using ISI Journal Citation Reports produced by Thomson Reuters,
and available scientometric data from the ISI Web of Knowledge and SCOPUS. The data presented in this paper and the analysis
shown may help the Editorial Board to further improve the journal into the direction of a high quality scientific journal
with even higher impact on the international research community in the field of landslide risk mitigation. 相似文献
