学术期刊的OA模式及其对学术交流系统的影响

介绍了学术期刊开放存取出版模式,分析了其产生的现实原因。对目前开放存取的运作模式、审稿方法、经费及版权等问题进行了阐述,分析了其对科研人员、出版机构、图书馆等传统学术交流系统的影响。指出了相关部门和人员应重视且积极试验学术期刊开放存取这种全新的出版模式,构建真正服务于科学研究的学术交流系统。

     

学报发行应建立"问责制"

作为主办单位的“窗口”,学报的发行往往与编辑职能混于一体,没有单独设立相应机构,发行数量长期偏低。阐述了学报发行现状,指出发行量过低的危害,提出学报发行“问责制”设想:成立学报发行委员会,负责承担发行责任;成立学报发行部(室);举办学报发行研讨会或年会等。并就搞好“问责制”应注意的几个问题加以说明。     

基于食用价值开发的桑树优势品种筛选

为科学评价我国桑树品种资源的食用价值,指导桑叶、桑椹的食用新产品开发,在对我国具有代表性的100份桑树品种资源的桑叶和桑椹进行营养品质、功能活性成分和加工特性鉴评的基础上,运用模糊数学中的隶属函数法对与桑叶蔬菜、桑叶茶和桑果汁(酒)的营养品质相关的各项指标数据进行转化,综合评价各品种的食用价值,筛选出一批食用优势品种。其中,最适合桑叶茶制作的10个桑树品种是粤诱35、粤诱19、任抗1号、粤诱33、抗10、粤诱18、鄂诱1、69、抗11、北-4-1,最适合桑叶蔬菜开发的10个桑树品种是粤诱35、任抗1号、英沙3、抗锈3号、坪镇2、粤诱19、抗10、粤诱25、抗11、白沙2,最适合果汁(酒)加工的10个桑树品种是粤椹15号(大10,无籽)、粤椹2号、粤椹18号、粤椹29号、粤椹27号、粤椹26号、粤椹33号、粤椹16号、粤椹66号、粤椹38号。目前种植面积较大的具有食用开发价值的桑树品种有适合果汁(酒)开发的品种大10,适合开发桑叶茶和桑叶蔬菜的品种抗10。另还确定了一批具有食用开发价值的优势储备桑树种质资源,可作为以食用价值开发为导向的桑树新品种选育的基础材料。     

Basic Technology and Recent Trends in Agricultural Formulation and Application Technology

Recent requirements of the pesticide industry have become much severer, and pesticides (formulated products) are required to satisfy higher safety to both human beings and the environment, higher biological efficacy, lower price, and labor-saving. This review explains the outline of basic pesticide formulation technology, followed by recent advances in developing new formulations and application technologies. Labor-saving formulations and application technologies, environmental load reduction technologies, and user-friendly formulations and application technologies are elucidated.     

从知行背离到知行统一——关于编辑职业道德建设的思考

对编辑职业道德生活中存在的知行背离现象进行了分析探讨,认为受编辑个体职业道德修养限制、知易行难、不良社会风气侵蚀、缺乏有效的约束机制等因素影响是导致知行背离的主要原因。指出应通过加强编辑道德修养、优化道德环境、完善约束机制等途径来促进编辑职业道德建设,推动出版事业健康发展。     

浅论期刊的编辑策划意识

期刊编辑策划是现代期刊在争夺眼球大战中不可或缺的手段。编辑策划是作为策划在编辑出版领域中的一种特殊表现形式,既具有一般策划的共性,又具有自身的特性。重视期刊的编辑策划是市场竞争的必然要求。

网络传播对高校学报出版的影响

网络作为一种新的信息传播载体,正逐渐向出版领域全面渗透。针对高校学报出版现状,分析了网络传播对高校学报的现实意义。同时提出了高校学报应把握好机遇,办品牌期刊,创特色栏目;提高编辑人员整体素质;走学报集团化之路,建立学术联合体,形成开放式传播。从而实现学术资源共享,促进学报为人类社会进步事业作出更大的贡献。     

Morphological fractions,chemical composition and in vitro digestibility of stover of four common vetch varieties grown on the Tibetan plateau

This study evaluated the varietal variability and interrelationship of the grain and stover yields, and stover quality characteristics of four common vetch varieties (three improved varieties and one local variety) used on the Tibetan Plateau. Stover quality attributes determined included chemical composition, in vitro true digestibility of dry matter (IVTD) and neutral detergent fibre (dNDF). The improved varieties were superior to the local variety in grain yield, harvest index and potential utility index (PUI). The wide ranges in the proportions of leaf (24.3%–34.6%), pod (22.0%–45.6%) and stem (29.5%–44.7%) fractions were observed. Significant varietal differences (p < .001) were observed for the whole‐stover content of crude protein [CP; 78.1–101 g/kg dry matter (DM)], neutral detergent fibre (aNDF; 520–564 g/kg DM), acid detergent fibre (ADF; 520–564 g/kg DM), IVTD (597–658 g/kg DM) and dNDF (305–384 g/kg aNDF). The leaf fraction had the highest levels of CP, IVTD and dNDF, while the highest contents of aNDF and ADF were observed in the stem fraction. Canonical correlation analysis showed that significant (p < .001) correlations between the quality attributes of whole stover and proportions and quality attributes of stover morphological fractions. Pearson correlation between the grain and stover yield was negative and significant (r = ?.295; p = .001), while the correlations between the grain/stover yield and stover quality traits were positive or non‐significant. Ranking of the varieties differed when grain yield, PUI and stover quality scores were investigated. Of the varieties tested, Lanjian No.2 has the best potential for use as a ruminant feed, as indicated by PUI and stover quality.
