Information Seeking Behavior Of Scientists In Venezuela, Simon Luis Aristeguieta Trillos

Doctoral Dissertations

Information is one the essential elements of science. It is an imperative condition that researchers review antecedent works as they advance and create new knowledge. Knowledge creation in science is a process of adding and refining new pieces of data, information, and knowledge to what has already been accomplished by others. Few scientific communities have unlimited access to scientific information sources. Most communities’ access to information is limited by economic, social, cultural, and technological conditions.

This study investigates information seeking behavior and information dissemination practices of the Venezuelan scientific community. A model of scholarly communication in a context of dependency …

The second objective is to study current literature that has been written by scholars and librarians on this medium. This exploration of graphic novels and comic books and the scholarship and collection development efforts related to them provides a foundation for considering the issues and challenges which current and future …

The Information Practices Of People Living With Depression: Constructing Credibility And Authority, Tami Oliphant

Electronic Thesis and Dissertation Repository

Depressive episodes and chronic depression often provide the impetus for both online and offline everyday life information-seeking and sharing and the seeking of support. While allopathic medication, psychiatric, and other biomedical services are the standard treatments for depression, people often use complementary and alternative medicine (CAM) to supplement or supplant biomedical treatments. Depression is a nebulous disorder with varying causes, illness trajectories, and a wide variety of potentially effective treatments. Often, treating and managing depression forms a project for life (Wikgren, 2001) where the need for information is continuous.

In the present study, I have used a constructionist, discourse analytic …

Cloud Storage And Online Bin Packing, Swathi Venigella

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cloud storage is the service provided by some corporations (such as Mozy and Carbonite) to store and backup computer files. We study the problem of allocating memory of servers in a data center based on online requests for storage. Over-the-net data backup has become increasingly easy and cheap due to cloud storage. Given an online sequence of storage requests and a cost associated with serving the request by allocating space on a certain server one seeks to select the minimum number of servers as to minimize total cost. We use two different algorithms and propose a third algorithm; we show …

Digital video currently faces challenges in defining and effectively managing metadata standards for media files, bridging a gap between traditional …

Archiving Transgender: Affects, Logics, And The Power Of Queer History, Kelly Jacob Rawson

Writing Program – Dissertations

Archiving Transgender:Affects, Logics, and the Power of Queer History examines three archives that collect transgender material in order to analyze archives as rhetorical sites where a complex interplay of language, politics, logic, and affect shape archival research. Current scholarship in rhetorical historiography has (re)turned to archives to consider the rhetorical dimensions of archives themselves and the impact these dimensions have on researchers (Kirsch and Rohan; Morris; Ferreira-Buckley). I extend and complicate this line of inquiry by focusing specifically on transgender archival practices and logics. Transgender archiving is an especially rich site for critical investigation because of the complexities of the …

A Comparative Study On Text Categorization, Aditya Chainulu Karamcheti

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automated text categorization is a supervised learning task, defined as assigning category labels to new documents based on likelihood suggested by a training set of labeled documents. Two examples of methodology for text categorizations are Naive Bayes and K-Nearest Neighbor.

In this thesis, we implement two categorization engines based on Naive Bayes and K-Nearest Neighbor methodology. We then compare the effectiveness of these two engines by calculating standard precision and recall for a collection of documents. We will further report on time efficiency of these two engines.

Information Privacy: A Quantitative Study Of Citizen Awareness, Concern And Information Seeking Behavior Related To The Use Of The Social Security Number As A Personal Identifier, Rhonda Marisa Clossum

Masters Theses

Information technology has transformed the manner in which personal identifying information is collected, stored and shared in government agencies and private businesses. The social security number has become the de facto identifier for individuals due to its notable qualities: a nine-digit number assigned to one person by the United States government. As individuals are increasingly asked to disclose personal information, the question arises: How does the lack of awareness of social security number laws contribute to the loss of privacy, loss of control of personal information and the threat of identity theft? This study examines awareness levels of social security …

Masters Theses

The system of Library of Congress Subject Headings (LCSH) has been the subject of feminist, critical examinations since the 1970s. Subject headings pertaining both to feminist literature and to women in general have been analyzed to determine how LCSH represents these topics. In this study, I contribute to this body of scholarship by analyzing and reporting on the nature of the LCSH subject representation of 52 core works published from 1986-1998 in the areas of feminist theory and women’s movements. These monographs were selected from the 3rd edition of Women’s Studies: A Recommended Bibliography (Krikos & Ingold, 2004). The analysis …

Genre, Database, And The Anatomy Of The Digital Archive, Elizabeth J. Vincelette

English Theses & Dissertations

The purpose of this study was to define shared characteristics of literary digital archives, specifically to explore how conceptual and structural qualities of such archives express generic qualities. In order to describe digital media such as database or digital archives, scholars resort to metaphors, and this study offers the metaphor of anatomy as a generic inscription with historical and methodological implications. The definition of the anatomy genre draws from Northrop Frye's in Anatomy of Criticism, in which Frye describes how anatomies are characterized by proliferating lists, the mixing of prose and non-prose forms, and self-reflexivity--under the guise of knowledge …

The Sunk Cost Fallacy And Individual Differences In Health Decisions, Norma P. Fernandez

Open Access Theses & Dissertations

The Sunk Cost fallacy is a biased committed when individuals base their decisions to stop or continue a course of action solely on past irrecoverable invested costs (i.e., monetary or time-related). Individuals' susceptibility to the Sunk Cost fallacy has been justified as the need to try to avoid appearing wasteful, to avoid appearing inconsistent, to learn a lesson from and to punish self for a poorly made decision. A study by Bornstein and Chapman (1995) evaluated these justifications along with a normative response and found statistical differences among all justifications. However, the study of the Sunk Cost fallacy and these …

Eliciting User Requirements Using Appreciative Inquiry, Carol Kernitzki Gonzales

CGU Theses & Dissertations

Many software development projects fail because they do not meet the needs of users, are over-budget, and abandoned. To address this problem, the user requirements elicitation process was modified based on principles of Appreciative Inquiry. Appreciative Inquiry, commonly used in organizational development, aims to build organizations, processes, or systems based on success stories using a hopeful vision for an ideal future. Spanning five studies, Appreciative Inquiry was evaluated for its effectiveness with eliciting user requirements. In the first two cases, it was compared with traditional approaches with end-users and proxy-users. The third study was a quasi-experiment comparing the use of …

Obscenity And Pornography: A Historical Look At The American Library Association, The Commission On Obscenity And Pornography, And The Supreme Court, Gretchen Brooke Gould

Dissertations and Theses @ UNI

There was a time when accessing pornographic and obscene materials was much more difficult than it is today. Prosecuted in 1868, Regina v. Hicklin was the first known obscenity case tried under the Obscene Publications Act in Great Britain. The United States Supreme Court first addressed obscenity in the 1957 case of Roth v. United States and grappled with setting standards or creating criteria by which obscenity could be defined. In the 1960s, multiple proposals for federal legislation to crack down on obscenity were offered. The American Library Association (ALA) stepped in to voice its concern and provide professional input …
