Alexa,Siri, Cortana,and More: An Introduction to Voice Assistants     

Matthew B. Hoy 《Medical reference services quarterly》2018,37(1):81-88

Voice assistants are software agents that can interpret human speech and respond via synthesized voices. Apple’s Siri, Amazon’s Alexa, Microsoft’s Cortana, and Google’s Assistant are the most popular voice assistants and are embedded in smartphones or dedicated home speakers. Users can ask their assistants questions, control home automation devices and media playback via voice, and manage other basic tasks such as email, to-do lists, and calendars with verbal commands. This column will explore the basic workings and common features of today’s voice assistants. It will also discuss some of the privacy and security issues inherent to voice assistants and some potential future uses for these devices. As voice assistants become more widely used, librarians will want to be familiar with their operation and perhaps consider them as a means to deliver library services and materials.  相似文献   

The effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion     

Jane L. Down 《文物保护研究》2016,61(1):26-45

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set^® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set^® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect.  相似文献

清代山西票号的激励机制及其对当代银行监管的启示     

杨兰 《韩山师范学院学报》2003,24(1):27-32

票号是19世纪中国历史上一个重要的金融组织，其中，最负盛名的是山西票号，它在没有政府监管的情况下，繁荣昌盛近一个世纪，后因战乱不断才逐渐倒闭并消失。山西票号的经营制度深谙委托代理之道，也就是今天在经济学界大行其道的激励理论，并形成了一套行之有效的激励机制。尽管时代和环境都发生了变化，激励问题是永恒的。山西票号的激励制度的启示对当代中国银行业监管效率的改进是有益的。  相似文献   

Pedagogical Agents as Learning Companions: The Role of Agent Competency and Type of Interaction   总被引：1，自引：0，他引：1  

Yanghee Kim  Amy L. Baylor 《Educational technology research and development : ETR & D》2006,54(3):223-243

This study was designed to examine the effects of the competency (low vs. high) and interaction type (proactive vs. responsive) of pedagogical agents as learning companions (PALs) on learning, self-efficacy, and attitudes. Participants were 72 undergraduates in an introductory computer-literacy course who were randomly assigned to one of four treatments: Low-Proactive, Low-Responsive, High-Proactive, and High-Responsive. Results indicated a main effect for PAL competency. Students who worked with the high-competency PAL in both proactive and responsive conditions achieved higher scores in applying what they had learned and showed more positive attitudes toward the PAL. However, students who worked with the low-competency PAL reported significantly enhanced self-efficacy beliefs in the learning tasks. Also, there was a main effect far PAL interaction type. A proactive PAL had a significantly positive impact on recall. These different results on learning and motivational outcomes suggest that the competency and interaction type of a PAL should be designed according to the desired learning and motivational goals.  相似文献

Information Provision by Public Library to Agricultural Extension Agents in a Developing Country     

Jerome Idiegbeyan-Ose  Ayotunde Owolabi  Chidi Segun-Adeniran  Ayooluwa Aregbesola  Sola Emmanuel Owolabi  Toluwani Eyiolorunshe 《Public Library Quarterly》2019,38(1):103-115

One of the bedrock of Sustainable Development Goals (SDGs) is eradication of poverty and hunger. In an attempt to actualize this goal, the role of public libraries in information provision to agricultural extension agents in Nigeria becomes paramount. This paper discusses provision of information to agricultural extension agents in a developing country. It starts with the concept of extension agents and the essence of information provision to them. It further discusses types, sources and challenges of public libraries in information provision to agricultural extension workers in a developing country. Some of the challenges are as follows: poor funding of public libraries, demotivated staff, and so on. Based on these discussions, the paper recommended adequate training and retraining of staff, adequate funding of public libraries by the federal, state and local government, the revitalization of the abandoned mobile library services among others. The paper therefore concludes that information provision to agricultural extension agents by public library is very crucial for national development. The current state of poverty, hunger and lack in Nigeria and some other African countries could be reduced to a great extent if current, relevant and up-to-date information are provided by libraries to the concerned agencies.  相似文献
