《古地理学报》创刊已经5周年了,创业维艰。现在已进入了发展阶段。其报道领域已由传统的岩相古地理学及沉积,构造古地理学及古构造、生物古地理学及古生态、古地理与矿产等,扩大到人类历史古地理学、人类文明、环境等。编辑质量和出版质量已达到了较好的水平。下一步的目标是在未来的3~5年内,努力向国内外尤其是国内地学界的优秀刊物学习,把《古地理学报》办成一流水平的学术期刊。  相似文献

Liberia and Sierra Leone are tragic examples of what happens when central authority collapses and warlords emerge as de-facto rulers over large portions of the national territory. Horrors inflicted on non-combatants and the well publicized trading in conflict diamonds served to focus world attention on these two small countries sharing a common border. Both countries have experienced mixed success with outside military intervention for peace keeping and nation building purposes. What has happened is all the more distressing when one considers each countrys prospects at birth under the political and economic aegis of arguably two of the most powerful and enlightened countries of the time, Great Britain in the case of Sierra Leone and the United States in Liberia.  相似文献

期刊评价形式很多,包括“核心期刊”评选、影响力排名等。正确把握各期刊评价体系的初衷和发展,了解其功能、指标及其测算方法的特定内涵,对于优化办刊理念、提高期刊质量具有重要意义。文章简要介绍了中文核心期刊和中国科技核心期刊评价体系及最新版评价采用的指标,分析了《水文地质工程地质》在前者中排位比较靠后、在后者中“红点指标”偏低的现状及其原因,认为决定期刊影响力的主要因子除了文章质量,还有文章体例的规范性及与被引量相关的各项指标。继而统计分析《水文地质工程地质》1年和10年刊文数据,获得该刊学科分布、文章影响力、摘要、关键词等方面的特点,认为存在学科比较分散、高影响力论文不多、摘要信息量不足和关键词不规范等问题。据此,提出了提升期刊影响力的措施:(1)办刊要坚持一定的学科方向和特色,合理控制学科分;(2)要规范要求文章体例,提高文章质量,吸纳高影响力论文,吸引高质量稿源;(3)加强摘要特别是英文摘要,扩充信息量,以促进文章的传播及期刊的国际化;(4)规范摘录关键词,提高文章被检索引用概率。并建议编辑要系统研究同一学科内期刊的特点,及时发现学科热点,更好地提升期刊的专业影响力。  相似文献
