Abstract

A compiled program, JCE-REFS.EXE (coded in the QuickBASIC language), for use on IBM-compatible personal computers is described. The program converts a DOS text file of current B-I-T-S (BIOSIS Information Transfer System) or BIOSIS Previews references into a DOS file of citations, including abstracts, in a general style used by scientific journals. The latter file can be imported directly into a word processor or the program can convert the file into a random access data base of the references. The program can search the data base for up to 40 text strings with Boolean logic. Selected references in the data base can be exported as a DOS text file of citations. Using the search facility, articles in theJournal of Chemical Ecology from 1975 to 1991 were searched for certain key words in regard to semiochemicals, taxa, methods, chemical classes, and biological terms to determine trends in usage over the period. Positive trends were statistically significant in the use of the words: semiochemical, allomone, allelochemic, deterrent, repellent, plants, angiosperms, dicots, wind tunnel, olfactometer, electrophysiology, mass spectrometry, ketone, evolution, physiology, herbivore, defense, and receptor. Significant negative trends were found for: pheromone, vertebrates, mammals, Coleoptera, Scolytidae,Dendroctonus, lactone, isomer, and calling.

摘要

描述了一个用于 IBM 兼容个人计算机的编译程序 JCE-REFS.EXE（用 QuickBASIC 语言编写）。该程序将当前 B-I-T-S（BIOSIS 信息传递系统）或 BIOSIS Previews 参考文献的 DOS 文本文件转换为引文的 DOS 文件，包括期刊中使用的一般样式的摘要。后者的文件可以直接导入字处理程序，或者程序可以将文件转换为参考文献的随机访问数据库。该程序可以使用布尔逻辑搜索数据库中多达 40 个文本字符串。数据库中的选定参考文献可以作为引文的 DOS 文本文件导出。使用搜索功能，对 1975 年至 1991 年《化学生态学杂志》中的文章进行了有关信息素、分类群、方法、化学类和生物术语的某些关键词搜索，以确定在此期间的使用趋势。在使用以下单词方面，阳性趋势具有统计学意义：信息素、他感物质、化感物质、驱避剂、驱避剂、植物、被子植物、双子叶植物、风洞、嗅觉计、电生理学、质谱、酮、进化、生理学、草食动物、防御和受体。发现以下单词的使用呈显著负趋势：信息素、脊椎动物、哺乳动物、鞘翅目、小蠹科、Dendroctonus、内酯、异构体和鸣叫。
