叙词表词间关系可视化实验研究

叙词表已有的参照系统及几种图形显示形式在网络环境中显然不能动态地、全面地显示词间关系,不便于浏览和检索。在分析本体编辑工具Protg实现叙词表可视化的必要性基础上,以《汉语主题词表》为例,利用Protg的可视化插件TGVizTab,进行叙词表等同关系、等级关系和相关关系的可视化实验,并讨论了整部关系和例举关系的可视化。     

论高校期刊编辑劳动的和谐品质

Cell调查报告

Cell创刊于1974年，是生命科学领域的综合性双周期刊，以报道生物学最优秀的研究发现而享誉国际学术界。其审稿流程快速灵活，编辑要求严格，每期内容主要分为研究论文（Research Article）以及前沿（Leading Edge）两大版块，文章多集中在分子生物学和基因工程领域。出版发行、广告收益和网络经营是Cell收入的主要来源。Cell网页界面简洁、内容丰富，可为读者提供多元的服务。对Cell出版模式进行分析，以期借鉴，发展自我。     

"物种混合"引起的伦理困境及其解决思路

用于治疗各种严重威胁人类疾病的基因移植和干细胞技术已经使制造越来越多的人兽混合体变得更容易和更迫切,当代社会出现了许许多多人兽混合的"喀迈拉"."喀迈拉"对人类伦理的挑战主要表现在:人体干细胞的来源、这些人兽混合体的生物学地位、社会地位和繁育后代等问题上都与人类的道德认同存在巨大反差.在对待"物种混合"引起的道德禁忌问题上,人类的态度应该更宽容一些.     

科技文稿处理中的服务理念

为作者服务是编辑处理文稿的重要行为准则.来稿复审后,以采用稿、退修稿和不用稿三种形式分流.对于采用稿,编辑要用"心"去品味,绞尽脑汁去琢,使文章更精美,以满足作者早出精品的迫切愿望.对于退修稿,编辑要想作者之所想,急作者之所急,尽自身之所能,以谋其完善.对于不用稿,编辑要公正无私,使作者心悦诚服.     

Letters to the editor on the Zika virus: a bibliometric analysis

Objective:To conduct a bibliometric analysis of Letters to the Editor published on the Zika virus from 1952–2018.Methods:A PubMed search was conducted using the terms (Zika OR ZIKV). Results were limited to 1952–2018 and Publication Type = Letter. Results were exported to EndNote, and the full text of each Letter examined. Each Letter was assigned to one of five categories: Reader Response, Author Reply, Observation, Case Report, or Research. Additional study parameters included number of authors, number of references, use of graphics, and funding. Citation reports were generated for each category and the entire dataset, producing lists sorted by Times Cited.Results:Of 499 Letters, only 15 (3.0%) were published before 2016. In 2016, at the height of the Zika virus epidemic in the Americas, 244 (48.9%) Letters were published, dropping to 145 (29.1%) in 2017 and 95 (19.0%) in 2018. Letters included 149 (29.9%) Reader Responses, 56 (11.2%) Author Replies, 112 (22.4%) Observations, 70 (14.0%) Case Reports, and 112 (22.4%) Research. The Letters were written by 1–35 authors; 369 (74.0%) Letters had 1–5 authors, and 130 (26.0%) had 6 or more. The Letters cited 0–63 references, with an average of 7.0 per Letter. Graphics appeared in 192 (38.5%) Letters, and 77 (15.4%) Letters reported funding. An interesting anomaly was the 104 (20.8%) Letters authored or co-authored by 1 individual.Conclusion:Letters to the Editor remain an important component of scientific communication and may serve as a valuable source of clinical and research information.

Structural changes of oviduct of freshwater shrimp, Macrobrachium nipponense （Decapoda, Palaemonidae）, during spawning

The structural change of the oviduct of freshwater shrimp （Macrobrachium nipponense） during spawning was examined by electron microscopy. The oviduct wall structural characteristics seem to be influenced significantly by the spawning process. Before the parturition and ovulation, two types of epithelial cells （types Ⅰ and Ⅱ） are found in the epithelium. The free surfaces of type Ⅰ and type Ⅱ cells have very dense long microvilli. Under the type Ⅰ and type Ⅱ cells, are a relatively thick layer of secreting material and a layer of mostly dead cells. After ovulation, two other types of epithelial cells （types Ⅲ and Ⅳ） are found in the oviduct wall epithelium. The free surface of type Ⅲ cells only has short microvilli scattered on the surface. The thick layer with secreting material and the dead cell layer disappeared at this stage. In some type Ⅲ cells, the leaking out of cytoplasm from broken cell membrane led to the death of these type Ⅲ cells. The transformation of all four types of epithelial cells was in the order： Ⅳ→Ⅰ→Ⅱ→Ⅲ.
