In 1713, the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images. This paper first analyzes his text and engravings in order to explain how he proposed to do this, given contemporary materials and command of physical forces. Next, it characterizes the devices as a transition from concepts of incision to concepts of mirroring, taken as models of the history of mechanical reproduction. And finally, Leupold’s replacement of the sighting grid with differential gears points to a set of problems appearing in contemporary philosophy represented in Rococo artistic production of this period as well. Taking the proposed devices in context, they help to theorize the complex notions of creative activity in Rococo visual culture. Taken as an episode in the history of communications, they instance the development of conceptions of personhood and of physical forces at stake in the invention of automated media. 相似文献

Summary Electronic reference is a large part of today's library. Computer technology has clearly been the dominant catalyst for change in library service over the last few decades. Reference service has changed along with the prevailing technology. An exclusive group of searchers serviced electronic information requests during the online searching craze of the 1970s and 1980s. In the library of today, this model of electronic reference is no longer operational. Electronic information is now available to anyone on a computer terminal. In response, all librarians have become familiar with computer technology, and have a new emphasis on teaching and basic information literacy. This article will examine how this came to be, and the technologies that helped make it happen. 相似文献

Summary An overwhelming majority (94%) of surveyed students rely on assistance from librarians (80%), professors (9%), and friends (5%) when using ERIC-on-CDROM, even when they are not first-time users. Almost three-quarters of the students report that ERIC-on-CDROM improves research quality (74%) and learning (70%) and evokes feelings of motivation and accomplishment (72%). All students indicate that they will return to use ERIC-on-CDROM but only 39% feel capable of transferring their skills to similar databases. Responses indicate that ERIC-on-CDROM contributes to highly individualized learning situations in which students successfully find information through assistance from both humans and computers. 相似文献

In the early 19th century, public libraries in America tended toward grand appearances befitting seriousness of purpose. Library design changed gradually throughout the 20th and 21st centuries, and more dramatically with automation and new technology. True to its roots, the public library continues to maintain areas for quiet, individual study. But, in addition, today’s library has become a cultural center in the community, offering art galleries, auditoriums, meeting rooms, spaces for collaborative work, digital information and instruction, and even cafés. Change is inevitable, as innovations in library design and patron use illustrate. Yet, from the earliest libraries to modern times, one overarching constant defines their purpose: libraries inspire. 相似文献

一切的声乐技能都是靠自己的意识来控制发声器官的,按照意识预定要求进行动作结果的。发声的各个器官的互相搭配其实也是人的一种本能的意识反应,建立科学发声状态是通过自身感觉的调控,使复杂的肌肉运动准确化、歌唱运用共鸣和呼吸合理化、技巧的掌握简单化,最后实现演唱的自动化。 相似文献

As primary source materials in the library are digitized and made available online, the focus of related library services is shifting to include new and innovative methods of digital delivery via social media, digital storytelling, and community-based and consortial image repositories. Most images on the Web are not of sufficient quality for most media outlets, so what happens when patrons require high-resolution versions of images for use in their print publications or projects? Until recently, patrons at the University of Houston Libraries used a clunky, paper-based request process for high-resolution images that was frustrating for them and time-consuming for staff. The authors of this article outline how an interdepartmental team of University of Houston Libraries staff used Drupal to develop an automated patron request system that is modeled after online shopping cart experiences and integrates with the CONTENTdm-based University of Houston Digital Library. The article provides suggestions for libraries with digital collections about how to create a system that efficiently captures patron requests and streamlines staff delivery of high-resolution files. 相似文献
