SUMMARY This article discusses issues surrounding the development of a small special library's Internet reference services to support firefighter distance learners for the University of Illinois Fire Service Institute's (IFSI) online Firefighter II Certification Program, the first of its kind in the nation. Planning for the Internet reference services involves consideration of user needs, funding, staff management, and collection development. In addition, this article explores how the IFSI Library has established a collaboration and partnership with the online course and Information Technology teams, and local public and community college libraries. 相似文献

SUMMARY The Internet Navigator, an online information literacy course developed by a team of academic librarians in Utah, offers a model for teaching independent research skills to remote students. The course uses an online textbook that doubles as a self-paced tutorial, and a set of assignments that take students step-by-step through the research process. Assignments are submitted by e-mail and evaluated by reference librarian/instructors. Questions on the assignments follow the pattern of a reference interview helping instructors guide students to use useful research strategies and information sources. Other methods of integrating reference services with online learning are discussed. 相似文献

ABSTRACT Federated searching has become an increasingly popular way for academic libraries to provide access to their diverse and rapidly growing collections of electronic resources. IUPUI University Library handled the implementation of its federated search project somewhat differently than many academic libraries. The cornerstone of their efforts was to not only create a gateway to the library's electronic resources, but to build upon previous experience as a beta site for Ex Libris' SFX cross-referencing software by using MetaSearch in conjunction with SFX to permit teaching faculty to link to online bibliographies through the university's course management system, Oncourse. Issues of working with two closed systems needed to be overcome, but a product resulted that was embraced by the faculty and gave direction for future developments. doi:10.1300/J136v12n03_04 相似文献

Abstract Serial cancellations have reduced the print newspaper collection at the University of Toledo (UT) Library by about one third since 1990. In the meantime, the number of newspapers publishing on the World Wide Web has skyrocketed, prompting UT to investigate accessing newspapers online. The immediate goal of this project is to provide library users with access to online versions of cancelled print newspapers, and eventually to enhance the collection even further with additional electronic newspapers. This article examines the trends in online newspaper publishing, researches the availability of Web sites in relation to the UT newspaper collection, critically reviews the sites found, and discusses the issues surrounding access to an online collection. 相似文献

Nonpublic participation within an online community, often called lurking, occurs when an individual joins a community, but
does not post. This study examines the nature of lurking, why people lurk and the differences in attitudes between lurkers
and posters. The results indicate significant differences between people who lurk and those who post in an online community.
We conclude that when people lurk they are observing, which in no way is a negative behavior. This introverted or passive
behavior affects lurkers' attitudes about the benefits of the community, their expectations, and opinions of themselves and
others who lurk. In general lurkers are less optimistic and less positive than those who post.

SUMMARY In order to provide online help for distance students, as well as the increasing number of on-campus students who regularly access library resources, a team of librarians from the Marshall University Libraries created an online library assistance site (HELP). This site brings together traditional print handouts, FAQs, online subject guides, course-specific guides, learning modules, and instructional videos in one central location where users can get assistance with library-related questions at their point of need. This article discusses the rationale for developing the site, the process of creating it and incorporating user input, ongoing content development, the impact upon the Libraries' Web site, and future development plans. 相似文献

This paper describes a system for visual object recognition based on mobile augmented reality gear. The user can train the
system to the recognition of objects online using advanced methods of interaction with mobile systems: Hand gestures and speech
input control “virtual menus,” which are displayed as overlays within the camera image. Here we focus on the underlying neural
recognition system, which implements the key requirement of an online trainable system—fast adaptation to novel object data.
The neural three-stage architecture can be adapted in two modes: In a fast training mode (FT), only the last stage is adapted,
whereas complete training (CT) rebuilds the system from scratch. Using FT, online acquired views can be added at once to the
classifier, the system being operational after a delay of less than a second, though still with reduced classification performance.
In parallel, a new classifier is trained (CT) and loaded to the system when ready.

This paper proposes an adaptive learning approach that yields decision models that can be applied by a transactions agent.
This model can learn effectively with a variety of data distributions. This research uses the Semantic Web as a data access
approach. The Semantic Web is a method that sellers can use to publish semantically meaningful information on Websites so
automated applications can reliably access that information. We implemented a Semantic Web composed of 30 vendors’ Web pages
and a spider to search those pages to obtain product and vendor information. This information was used to train a learning
agent, which then provided a decision model to a transaction agent.

ABSTRACT Librarians at Oregon State University (OSU) Libraries used the discussion board features of Blackboard courseware to create an interactive experience for graduate students at a distance who could not attend the on-campus “Literature Review Workshops.” These recently developed workshops have been extremely popular with graduate students across the disciplines and have generated a growing demand from distance education graduate students and faculty to offer similar information online. Reluctant to simply deliver content via an online tutorial, librarians sought to duplicate the workshop atmosphere by making the sessions available for a short time-period online, asking participants to respond to discussion questions at specific points in the workshop, and offering audio-mediated online demonstrations of tools and resources. Student feedback and follow-up requests for more workshops support the perception that this approach offered a rewarding learning experience that addressed their specific adult learning needs. 相似文献

SUMMARY The University of Wyoming has a long tradition of providing library services to distance education students. As technology changed and enhanced the delivery mode of distance education courses, the library altered the ways in which it offered services to distance learners. The institution was an early adopter of Web courses, so offering library support in this new environment was a natural expansion of our services. This expansion supports the goals of the ACRL Guidelines for Distance Learning Library Services and the goals of the University. This article will describe the integration of library reference services into online courses. 相似文献

ABSTRACTProblem: Online higher education (OHE) failure rates reach 40% worldwide. Prediction of student performance at early stages of the course calendar has been proposed as strategy to prevent student failure.Objective: To investigate the application of genetic programming (GP) to predict the final grades (FGs) of online students using grades from an early stage of the course as the independent variableMethod: Data were obtained from the learning management system; we performed statistical analyses over FGs as dependent variable and 11 independent variables; two statistical and one GP models were generated; the prediction accuracies of the models were compared by means of a statistical test.Results: GP model was better than statistical models with confidence levels of 90% and 99% for the training testing data sets respectively. These results suggest that GP could be implemented for supporting decision making process in OHE for early student failure prediction. 相似文献

I can’t get no satisfaction: How bundling and multi-part pricing can satisfy consumers and suppliers
Bundling and multi-part pricing may save etailers from mortal challenges attacking the music industry. These strategies are
attractive to customers, perhaps spelling the difference between pirating and legally purchasing music; they allow “custom
pricing” to capture more of the consumer surplus, and just as importantly, they contribute to developing new artists for long-term
viability of the music industry. The many ways to bundle include exact firm-selected bundles, category bundling, customer-selected
bundles, and mixing these with individual products. Each of these approaches has specific advantages for different market
segments, making up for generally lower prices in the competitive online world. Multi-part pricing affords additional opportunities
to capture more of the consumer surplus. These ideas are especially relevant to online music because of the ease of packaging
products, the low cost of reproducing music on demand, the reduced friction of consumer/firm interaction, the low cost of
monitoring complex behavior, and the enhanced measurement of performance. In the online world, content offerings are revitalized
when offered as bundles or service packages.

SUMMARY As distance education courses increasingly move to the online environment, librarians are discovering new challenges and opportunities for reaching distant students. Collaboration with faculty is essential in reaching students who may never enter the library building. One such method of collaboration is librarian participation in online courses through “lurking” in Blackboard and Desire2Learn classrooms and monitoring discussion threads devoted to library research. Advantages such as improved access to students, course content, and assessment data are discussed, as are disadvantages, such as time commitment, varying expectations, and privacy issues. Considerations for librarians interested in “lurking” are outlined. 相似文献

This paper investigates a preemptive semi-online scheduling problem on m identical parallel machines where m = 2,3. It is assumed that all jobs have their processing times in between p and rp (p > 0, r≥1). The goal is to minimize the makespan. Best possible algorithms are designed for any r≥1 when m = 2,3. 相似文献

For most scheduling problems the set of machines is fixed initially and remains unchanged for the duration of the problem.Recently Imreh and Nogaproposed to add the concept of machine cost to scheduling problems and considered the so-called List Model problem.An online algorthm with a competitive ratio 1.618 was given while the lower boud is 4/3.In this paper,two different semi-onlne versions of this problem are studied‘.In the first case,it is assumed that the processing time of the largest job is known a priori.A semi-online algorithm is presented with the competitive ratio at most 1.5309 while the lower bound is 4/3,In the second case,it is assumed that the total processing time of all jobs is known in advance.A semi-online algorithm is presented with the competitive ratio at most 1.414 while the lower bound is 1.161.It is shown that the additional partial available information about the jobs leads to the possibility of constructing a schedule with a smaller competitive ratio than that of online algorithms. 相似文献

Students' experiences with PDAs for reading course materials 总被引:1,自引:0,他引:1
The availability of text reading and editing software for Personal Digital Assistants (PDAs) makes it timely to consider
whether PDAs are useful tools for reading learning materials. This paper describes a study that evaluated the use of PDAs
for reading by students on a Masters course run by the UK Open University. The evaluation consisted of pre- and post-questionnaires,
and follow-up interviews. In addition, students discussed their experiences in a computer-based conference. Findings show
that while the portability of the device was welcomed by students, and the electronic format was advantageous, limitations
such as the small screen size, navigation difficulties, and slow and error-prone methods for entering text, made it difficult
to read and interact with documents on the PDA. The paper recommends that further research consider the value of PDAs as reading
devices in the context of other potential ways that PDAs can be used as learning tools.

Mining frequent patterns has been studied popularly in data mining area. However, little work has been done on mining patterns when the database has an influx of fresh data constantly. In these dynamic scenarios, efficient maintenance of the discovered patterns is crucial. Most existing methods need to scan the entire database repeatedly, which is an obvious disadvantage. In this paper, an efficient incremental mining algorithm, Incremental-Mining (IM), is proposed for maintenance of the frequent patterns when new incremental data come. Based on the frequent pattern tree (FP-tree) structure, IM gives a way to make the most of the things from the previous mining process, and requires scanning the original data once at most. Furthermore, IM can identify directly the differential set of frequent patterns, which may be more informative to users. Moreover, IM can deal with changing thresholds as well as changing data, thus provide a full maintenance scheme. IM has been implemented and the performance study shows it outperforms three other incremental algorithms: FUP, DB-tree and re-running frequent pattern growth (FP-growth). 相似文献

SUMMARY The School of Information Resources and Library Science at the University of Arizona (UA) has a mix of local and distance students in its program. The librarian at the UA Library who works with this program developed a Web site that centralizes information about several library services and resources that benefit distance learners: online orientation and research guides, chat reference, document delivery, and more. Bringing together this information with a focus on distance learners provides a platform for delivering the library to all users, whatever their distance from the library. 相似文献

ABSTRACT This paper describes the process and creation of a library resources and services Web page within WebCT, a course authoring program that is being used to deliver complete course content over the Internet in a distance education program at The Ohio State University. A librarian at the Prior Health Sciences Library was asked to join a faculty team to teach and provide library services for a series of three courses. The students are working health professionals who cannot attend regularly scheduled classes. Illustrations are included of the WebCT course page and the library resources and services page. The initial process and planning are described, and recommendations for future research are identified. 相似文献

A separation method for DNA computing based on concentration control is presented. The concentration control method was earlier
developed and has enabled us to use DNA concentrations as input data and as filters to extract target DNA. We have also applied
the method to the shortest path problems, and have shown the potential of concentration control to solve large-scale combinatorial
optimization problems. However, it is still quite difficult to separate different DNA with the same length and to quantify
individual DNA concentrations. To overcome these difficulties, we use DGGE and CDGE in this paper. We demonstrate that the
proposed method enables us to separate different DNA with the same length efficiently, and we actually solve an instance of
the shortest path problems.
