A spectral estimation of tempered stable stochastic volatility models and option pricing
No full textThis paper considers alternative option pricing models and their estimation. The stock price dynamics is modeled by taking into account both stochastic volatility and jumps. Jumps are captured by the tempered stable process and stochastic volatility is introduced via time changing the stochastic processes. We propose a characteristic function based iterative estimation method, which overcomes the problem of non-tractable probability density functions of the models and facilitates computation. Estimation results and option pricing performance indicate that the infinite activity stochastic volatility model dominates the finite activity model. We also provide an extension to investigate the double-jump model by introducing jumps in the variance rate process
Heat transfer and visualization of flow boiling on nanowire surfaces in the microchannel
No full textEnhancing heat transfer efficiency is crucial in heat exchange equipment. Although previous studies have focused on developing micro/nano-structured surfaces, further exploration into how surface structure can improve heat transfer efficiency (H) by altering bubble dynamics is still needed. This study aimed to innovatively analyze the impact of titanium carbide (TiC) nanowire heights-specifically 4 mu m and 12 mu m-on boiling heat transfer performance. Conducted under varying heat flux (Q) (50-200 W/m2) and mass flux (G) (200-300 kg/m2 & sdot;s), our experiments assessed H, pressure drop (P), and local boiling curves. Using a high-speed camera, we observed complex periodic flow patterns on the 4 mu m nanowire surface, including elongated bubble formation, expansion, local dryout, and subsequent fluid rewetting. Results showed that the 12 mu m nanowire surface increased H by up to 19.84% in single-phase conditions, while the 4 mu m nanowire surface increased H by up to 27.9% in two-phase conditions. These findings highlight the significant role of nanowire length and arrangement in optimizing boiling heat transfer performance. This work lays a foundation for further investigations into diverse nanowire materials and configurations
Assessment of Self-Archiving in Institutional Repositories: Depositorship and Full-Text Availability
No full textThis research evaluates the success of open access self-archiving in several well-known institutional repositories. Two assessment factors have been applied to examine the current practice of self-archiving: depositorship and the availability of full text. This research discovers that the rate of author self-archiving is low and that the majority of documents have been deposited by a librarian or administrative staff. Similarly, the rate of full-text availability is relatively low, except for Australian repositories. By identifying different practices of self-archiving, repository managers can create new strategies for the operation of their repositories and the development of archiving policies

Information Literacy and Librarian-Faculty Collaboration: A Model for Success:
No full textIn the age of information explosion and technological advancement, issues of information storage, organization, access, and evaluation have become necessarily important in our societies. Addressing issues of information literacy and designing how they can be best integrated in students' learning process are of critical importance. Library professionals in the United States, particularly in the academia, have realized the importance of information literacy and have attempted in various ways to address these issues. The ultimate goal is to make information literacy an integral part of the academic curriculum, thus helping students to succeed not only during their years in college but also for their lifelong career choices. This article will look at ways of how information literacy can best be incorporated into students' academic experience, and how this process can make students' learning meaningful and successful. Specifically, the author will examine the model of librarian-faculty collaboration in integrating information literacy into the curriculum, as demonstrated in the Ohio Five Colleges' Information Literacy Program.Publisher version of this article is available at: http://www.white-clouds.com/iclc/cliej/cl24.ht
Factors to Assess Self-Archiving in Institutional Repositories
No full textThis paper proposes a group of factors that may be used to assess the success of open access self-archiving. It concentrates on self-archiving in institutional repositories. The authors emphasize the importance of examining content materials, particularly the availability of full text versus abstracts and the deposits archived by authors versus by others.Peer reviewe
Applying the NISO Metasearch Initiative Scheme to Enhance E-Resources Management at Rutgers University Library
No full textThis paper discusses problems in the management of library e-resources and attempts to identify potential solutions to the problems. By describing an e-resources enhancement project taken by Rutgers University Libraries, this paper points to the importance of providing contextually-rich metadata and reorganizing the accessibility of e-resources on a library’s website. It introduces how this Rutgers project adopted the National Information Standards Organization Metasearch Initiative to support the identification of appropriate e-collections for metaseaching. The outcomes of the project have facilitated a dynamic display of relevant e-resources to library users as an effective way of automatic access to library e-collections.Peer reviewe
A Metadata Manager's Role in Collaborative Projects: The Rutgers University Libraries Experience
No full textPurpose – This article discusses the roles and responsibilities of a metadata manager in collaborative digital projects.
Methodology – It describes the general requirements for metadata management, and introduces some scenarios in the practices of digital projects by the Rutgers University Libraries to support the generalized definition. A workflow of metadata management is illustrated.
Practical implications – With an explicit definition of the roles and responsibilities of the metadata manager, many other digital libraries that need to develop a new or optimize the existing workflow may find the Rutgers experience useful as reference.
Originality – Very few articles have explored this topic although the functions of metadata in the development of digital projects have been talked extensively.Peer reviewe
