Long-Term Memory for Context-Specific Category Information at Six Months

The ability of 6-month-old infants to remember a functional category acquired in a specific context was assessed in 3 experiments via an operant procedure in which infants learned to perform a specific action (a footkick) to activate an object suspended before them. In Experiment 1, infants trained with different exemplars in the same context transferred responding to a novel exemplar in the same but not a different context 24 hours later. Experiment 2 revealed that infants' reactivated memory of category training remained intact and context-specific after 3 weeks. In Experiment 3, a novel category exemplar was able to reactivate the forgotten memory of category training only in the encoding context. At 6 months, information about the place where categories are constructed is prerequisite for retrieval of a category concept from long-term memory. This requirement insures that early category concepts remain stable over relatively long periods.     

Computing and the social organization of academic work

This article discusses the academic computing movement during the 1980s. We focus on the Faculty Workstations Project at Brown University, where major computing initiatives were undertaken during the 1980s. Six departments are compared: chemistry, cognitive and linguistic sciences, geology, music, neural science, and sociology. We discuss the theoretical implications of our study for conceptualizing the relationship of computing to academic work.An early version of this article was originally published as: Technological Innovation in Higher Education: A Case Study in Academic Computing.

A Two-Pronged Approach to Promote Food Science in U.S. High Schools

ABSTRACT:  The Institute of Food Technologists (IFT), the IFT Foundation, and Discovery Education partnered to create and distribute food science information to science department and school counselor chairs in all 18000 U.S. high schools in January 2006. Two multimedia "kits" were generated for teachers and counselors, each consisting of DVDs with food science technical or career information, respectively, and a call to action to visit a newly created web microsite. To support and promote the program, IFT initiated a "Food Science Ambassador" program, where IFT member food scientists complete a brief survey indicating their interest in speaking with or visiting teachers, students, and counselors to discuss the field of food science or give a demonstration. IFT, through the career guidance committee, exhibited and conducted workshops at the National Science Teachers Association regional and national conferences, and coordinated a "Train the Trainer" program at the IFT Annual Meeting in Florida for local area science teachers and Food Science Ambassadors. Survey results from kit recipients were overwhelmingly positive, with over 97% of the respondents indicating that they intend to use the materials. The microsite developed for this program received over 18000 unique visits in the first 6 mo, and traffic to the IFT Teacher Resources web page increased. In the first 6 mo of its availability, nearly 250 IFT members have signed up to be Food Science Ambassadors. Long-term metrics for success are in place and continue to be monitored.

健康信息需求分析及相关网络资源的使用——对达拉斯福和地区华人的调查

本文阐述了一项由全美医学图书馆联盟中南区中心资助的研究项目。其目的是了解北美华人对健康信息的需求及网络健康信息资源的使用状况。本研究回收了101份调查表。研究结果发现调查对象有兴趣了解更多关于乳腺癌、糖尿病、乙型肝炎等疾病的信息,愿意学习如何使用互联网络查找高品质的健康信息资源。语言障碍以及对美国医疗体系知识的缺乏了解是调查对象在获取医疗健康信息中遇到困难的主要原因。面对这些需求和问题, 指出认识语言和文化的差异性,推荐权威性、可靠性、针对性强的高质量的健康信息资源,介绍网络健康信息质量评估方法, 将有助于对华人的医疗健康信息服务。
