Hydroelastic waves propagating in an ice-covered channel
The hydroelastic waves in a channel covered by an ice sheet, without or with crack and subject to various edge constraints at channel banks, are investigated based on the linearized velocity potential theory for the fluid domain and the thin-plate elastic theory for the ice sheet. An effective analytical solution procedure is developed through expanding the velocity potential and the fourth derivative of the ice deflection to a series of cosine functions with unknown coefficients. The latter are integrated to obtain the expression for the deflection, which involves four constants. The procedure is then extended to the case with a longitudinal crack in the ice sheet by using the Dirac delta function and its derivatives at the crack in the dynamic equation, with unknown jumps of deflection and slope at the crack. Conditions at the edges and crack are then imposed, from which a system of linear equations for the unknowns is established. From this, the dispersion relation between the wave frequency and wavenumber is found, as well as the natural frequency of the channel. Extensive results are then provided for wave celerity, wave profiles and strain in the ice sheet. In-depth discussions are made on the effects of the edge condition, and the crack
Assessment of Self-Archiving in Institutional Repositories: Depositorship and Full-Text Availability
This 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
Natural Modes of Liquid Sloshing in a Cylindrical Container with an Elastic Cover
Liquid sloshing and its interaction with an elastic cover in a cylindrical tank is considered. The velocity potential for the fluid flow is expanded into the Bessel-Fourier series as commonly used. An efficient scheme is then developed, which allows the plate deflection to use the same type of expansion as the potential. When these two series are matched on the interface of the fluid and the plate, the unknown coefficients in the two expansions can be easily obtained. This is much more convenient than the common procedure where a different expansion is used for the plate and upon matching each term in the series of the plate is further expanded into the series used for the potential. Through the developed method, an explicit equation is derived for the natural frequencies and extensive results are provided. The corresponding natural mode shapes and principal strains distribution of the elastic cover are also investigated. Results are provided and the underlining physics is discussed. To verify the obtained results, the problem is also solved through a different method in which the potential is first expanded into vertical modes. Another explicit equation for the natural frequencies is derived. While the equation may be in a very different form, through the residual theorem, it is found that the second equation is identical to the first one
Information Literacy and Librarian-Faculty Collaboration: A Model for Success:
In 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
This 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
This 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
Purpose – 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
Macropsis zizhongi Li, Dai et Li

Etymology. The species is named in honour of Prof. Li Zizhong, the first author of the original species name.Published as part of Li, Hu, Dai, Ren-Huai, Li, Zi-Zhong & Yu, Dmitri, 2012, Taxonomic study of Chinese species of the genus Macropsis (Hemiptera: Cicadellidae: Macropsinae): new species, new records, synonymy and replacement name, pp. 41-62 in Zootaxa 3420 on page 61, DOI: 10.5281/zenodo.21216
Batch Loading in Metadata Creation: A Case Study the Rutgers University Libraries Experience
Purpose – The purpose of this article is to describe a workflow of automated batch loading metadata from existing text to a database.
Methodology/Approach – It introduces a case for the experience of metadata creation at Rutgers University Libraries in a collaborative digital project with the Hoboken Public Library in New Jersey.
Findings – It is found that a well-designed workflow is crucial to the success of metadata batch loading. It is also found that the metadata manager needs to collaborate with people of different roles and work carefully with data reorganization and transferring.
Practical Implications – Metadata creation and management is an integrated component of any digital project. Our experience in metadata batch loading has practical significance that may be incorporated into the practice of other metadata projects. The workflow introduced in this article will provide valuable example for librarians and information professionals to consider or redesign their own digital efforts.
Originality – Based on our real exercise, this workflow has been proven to be unique and useful. It was, after the writing of this article, applied to a new collaborative digital project and once again fulfilled the requirements for another batch transferring process.Peer reviewe
