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
Development of Immunoprecipitation Protocols to Isolate Plasma Lipoproteins for use in Characterizing the Alzheimer’s disease Plasma Lipoproteome
No full textFaculty Advisor: Danni Li, Ph.D.Fractionating human plasma into density groups (e.g., HDL) allows for more effective identification of differences in plasma proteins between non-AD patients and AD patients. The current standard for fractionating plasma lipoproteins is ultracentrifugation, however, this is both time and labor intensive and impractical for clinical use. Apolipoprotein AI (ApoAI) is a major protein on HDL. The objective of this study was to develop an immunoprecipitation protocol to isolate HDL from human plasma. ApoAI specific antibodies coupled to magnetic beads were used to precipitate ApoAI from human plasma samples. ApoAI was then eluted from the beads, digested using a trypsin digest protocol, and measured by a liquid chromatography-mass spectrometer (LC-MS). Results from the LC-MS were used to determine the successful isolation of HDL and identify other co-isolated proteins from the plasma. In the future, antibodies specific to other plasma fractions (e.g., chylomicrons, VLDL, IDL, LDL) will be used to isolate those fractions from plasma samples.This research was supported by the Undergraduate Research Opportunities Program (UROP).Bhalerao, Aniket; Flaten, Zach; Li, Danni.

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

No full textPh.D.Sodium ion batteries (SIBs) are promising alternative for lithium ion batteries, due to the high abundance and wide distribution of sodium sources in the earth thus the lower price than the lithium source. In the present thesis, we have investigated several P-based anodes for SIBs.We start our study with tin phosphide (Sn₄P₃). Using the solution-liquid-solid (SLS) method, we have synthesized the phase pure Sn₄P₃ nanotops. The electrochemical performance of them are also performed, we find that they mainly suffer from the fading of the cycle stability. Ex-situ XRD reveals that the Sn aggregation contributes to this fading, other reasons could be the volume expansion and the unstable solid electrolyte interface (SEI).We then try to introduce the second phase SbSn to address the issues of the Sn₄P₃. We propose to make a Sn₄P₃@SbSn core-shell structure, however, the obtained Sn4P3/SbSn composites show side by side structure. Even though, the obtained performance of this composite is still better than that for the phase pure Sn₄P₃ anode.We also make a ternary phosphide, Cu₄SnP₁₀, we expect that introducing Cu would help to address the problems of either Sn or P. It's the first time for us to find the anode reactivity of this phosphide for SIBs. Phase pure Cu₄SnP₁₀ nanowires show high capacities of ~800 mA h g⁻¹ but limited cycle stability. We then make the Cu₄SnP₁₀ /MWCNTs composites for longer cycle stability anode.Different from forming phosphide, we finally investigate the P composites based materials, including the P-Ti-C and P-TiO₂-C composites. The local chemistry of P in those composites is manipulated. P-Ti-C shows the longest cycle stability among all investigated samples (~220ᵗʰ with capacity of ~400 mA h g⁻¹). Due to the low P ratio, the capacity of the P-Ti-C is limited. Learning from the P-Ti-C, we then obtain P-TiO₂-C composites with higher P ratio, it shows a high reversible capacity of 1147 mA h g⁻¹ at a current density of 100 mA g⁻¹ with good cyclability.鈉離子電池被認為是理想的鋰離子電池替代品，主要是因為金屬鈉資源在地球上比鋰資源豐富且分布廣泛，從而比金屬鋰便宜。在本論文中，我們主要研究了幾種鈉離子電池磷基負極材料。我們的研究從磷化錫材料（Sn₄P₃）開始。通過溶劑-液態-固體的合成方法，我們合成了磷化錫納米錐。我們測試了這個材料的電化學性能，發現這個材料主要受限於循環穩定性的衰落。通過非原位XRD 測試，我們發現錫的偏析和團聚將會導致材料的穩定性衰落。其他衰落的原因可能來自於材料的體積膨脹和不穩定的固態電解質界面膜。我們接著通過引入錫化銻（SbSn）去解決磷化錫的問題。我們本打算設計一個錫化銻包覆磷化錫的（Sn₄P₃@SbSn）核殼結構。然而，最後獲得的是一個錫化銻和磷化錫肩並肩的納米復合結構。即使如此，這個復合材料的電化學性能仍然比單純的磷化錫材料要好。我們也制備了三元磷化物材料，銅錫磷（Cu₄SnP₁₀），我們希望通過銅的引入可以緩解錫和磷材料的不足。我們第一次發現銅錫磷這個三元材料具有做為鈉離子電池材料的活性。然而，單一的銅錫磷納米線有大概800 mA h g⁻¹ 的容量，但是循環次數有限。我們最後合成了銅錫磷/多壁碳納米管復合材料，獲得了更高的循環穩定性。與制備磷化物不同，我們最後也研究了磷基復合材料，包括磷鈦碳（P-Ti-C）和磷二氧化鈦碳（P-TiO₂-C）復合材料。在這類材料中，磷周圍的化學環境被修飾。在所有研究的材料中，磷鈦碳材料表現出最長的循環穩定性（循環200 圈後容量依然有大概400 mA h g⁻¹）。由於磷的含量較低，磷鈦碳材料的容量受限，基於磷鈦碳材料，我們接著研究了磷二氧化鈦碳（P-TiO₂-C）復合材料，通過提高磷的含量，這個材料表現出更高的容量（1147 mA h g⁻¹），循環穩定性也較好。Lan, Danni = 鈉離子電池磷基負極材料的開發 / 蘭丹妮.Thesis Ph.D. Chinese University of Hong Kong 2019.Includes bibliographical references (leaves 81-90).Abstracts also in Chinese.Title from PDF title page (viewed on 25, November, 2020).Lan, Danni = Na li zi dian chi lin ji fu ji cai liao de kai fa / Lan Danni
