The authors discuss a newly established academic library at the University of California, Merced, as a model for reference service that foregoes a desk staffed with reference librarians. The library provides innovative, quality reference services for its users by using well-trained staff at a library services desk and employing new technologies for asynchronous communication and instruction. 相似文献

Electoral processes are complex and need to be secure, reliable, and auditable. It is then important to define ways to evaluate their functional completeness and correction as well as their security and reliability. Many solutions to specific aspects of voting have been proposed but we do not know of any holistic view of this process. We present a unified approach to elections based on a conceptual model built using software patterns. A set of analysis patterns describe the structure and management of an election. The patterns describe voter registration, ballot structure, election day management, voting process, and the complete election. A conceptual model is built from the analysis patterns and defines precisely the functional properties of such a system together with its security requirements. The conceptual model is defined using UML diagrams that can be extended or complemented with formal methods to make the system verifiable. We show how to continue to the design phase for this system. While the model will not apply exactly to all elections it can be used as a reference architecture for voting applications and to show explicitly the security considerations for these kind of events. It can also be used for existing elections to verify that they have the required security provisions. The model can also be used as a reference for researchers to integrate their solutions in the complete process. 相似文献

ABSTRACTMechanical properties of aged beeswax were studied by an indirect measurement, using hydrogenated beeswax as a model material. The adequacy of the model was evaluated by comparison of its chemical composition and thermal properties with those of samples of historical beeswax. It was found that the gradual decrease in content of unsaturated compounds in beeswax contributes significantly to changes of its mechanical properties. As a consequence, beeswax artefacts become increasingly prone to mechanical damage during natural ageing. Understanding the difference between mechanical properties of recent and historical beeswax is primarily important from the point of view of safe handling and storage of such artefacts. Besides, this knowledge could help conservation scientists, e. g. when preparing model samples for testing new conservation methods. 相似文献

This article introduces the use of choice-based conjoint analysis to measure the content preferences of newspaper readers. Its importance lies in its role as part of an economic theory of newspaper finance that connects various measures of news quality to circulation and to circulation revenue. In addition, choice-based conjoint provides another way to operationalize “quality” in terms of how much readers like various kinds of content and the relative amounts of that liking. Content preferences were obtained from a large sample of readers of a newspaper of about 100,000 in circulation from the Southeastern United States using the proposed methodology and subsequently, the results were used by the newspaper to modify its content accordingly. Four months after the content changes were made, the publisher of the newspaper reported a significant maintenance of circulation even as print price was increased by 75%. The findings are consistent with the economic model of newspaper demand, and suggests that preferences measured using choice-based conjoint provide impetus for making key management decisions. 相似文献

图书借阅流量行为季节预测模型 总被引：2，自引：0，他引：2
指出图书借阅流量行为预测是图书借阅行为学的一个重要研究方向,常规的借阅流量预测大多采用的是ARIMA时间序列模型,但普通时间序列预测模型的参数难以估计并且模型较难处理非平稳时间序列问题。基于时间序列的神经图书借阅模型研究是,根据图书借阅流量行为的季节性特点,提出季节型神经图书借阅模型。用模型对图书借阅流量行为的预测分析表明,该模型预测效果较好,结果合理,对进行图书借阅实时监控及图书借阅管理都具有一定的理论和实践价值。 相似文献

The purpose of this study is to conceptualize a digital library acceptance model and its validation. Based on the extant literature and interviews with experts, a sixty-three statement questionnaire was developed and a survey was conducted to test the proposed model. The target population included library professionals and users from academic institutions in India including faculty, graduate students, and undergraduate students. These sixty-three statements were categorized into seventeen dimensions on the basis of the Unified Theory of Acceptance and Use of Technology model and two information success models. The model was tested using exploratory and confirmatory factor analysis. The findings suggest that digital libraries can become more useful and acceptable to targeted user groups when they are developed in accordance with four major factors: systemic aspects, informational aspects, perception of the relevant social group, and user learning. This study is unique as it is the first time such a model has been developed for digital libraries with respect to social construction. 相似文献

A formal model of the scientific communication process is presented using the IDEF0 notation. The model provides a roadmap for policy discussions and further research. In comparison to earlier models it is more detailed and hierarchical, and includes more modelling constructs. It includes the whole communication value chain, from initial research to the assimilation of research results to everyday practice. Although the model treats both informal and formal communication, as well as the publishing of data, its focus is on modelling the publishing and indexing of traditional peer‐reviewed journal articles, and finding and retrieving them. New developments enabled by the Internet, such as open access journals and e‐print repositories, are also included. 相似文献

With support from the National Library of Medicine, the University of Maryland at Baltimore is creating an Integrated Academic Information Management System (IAIMS) that will serve as a prototype for academic health centers. A campus-wide undertaking, the IAIMS initiative at Maryland is characterized by its functional comprehensiveness and its planning model. The resulting strategic plan is serving as a guide in the ongoing model development within an interdisciplinary Hypertension Center. 相似文献

This paper tells the story of the multi-layered translational process of the Drug Resistance Strategies Project. The Drug Resistance Strategies Project provides an exemplar of translational scholarship, translating adolescent narratives about their substance use experiences into an efficacious, substance abuse prevention middle school curriculum. The curriculum, called keepin' it REAL, was developed using the principle of cultural grounding and translational performances and has been found to reduce adolescent substance use. The authors tell the story of this project from its inception to its current role as a model substance abuse prevention program. 相似文献

ABSTRACTThis paper proposes a new way of interpreting particulate matter deposition indoors. The rate of deposition of dust in surfaces is presented as the result of the combination of two main factors: the concentration of suspended particles close to surfaces, and their capacity to deposit, expressed as the deposition velocity. We suggest that either of these two factors can be altered in order to mitigate deposition. The implications of this perspective are explored using in-situ measurements in a historic property (Apsley House, London) and a computational fluid dynamics model of aerosol deposition. The cases studied involve the effect of outdoor wind on the ingress of particles, the consequences of leaving the main door open, and the effects of the ventilation system on deposition. The results demonstrate that simulations can be used reliably to explore hypothetical scenarios or situations that would be experimentally challenging. The inputs and outputs of the computational model are discussed in view of its usability in preventive conservation. 相似文献
