Evaluation of Text-Based and Image-Based Representations for Moving Image Documents

Description: Document representation is a fundamental concept in information retrieval (IR), and has been relied upon in textual IR systems since the advent of library catalogs. The reliance upon text-based representations of stored information has been perpetuated in conventional systems for the retrieval of moving images as well. Although newer systems have added image-based representations of moving image documents as aids to retrieval, there has been little research examining how humans interpret these … more

Diagnosing Learner Deficiencies in Algorithmic Reasoning

Description: It is hypothesized that useful diagnostic information can reside in the wrong answers of multiple-choice tests, and that properly designed distractors can yield indications of misinformation and missing information in algorithmic reasoning on the part of the test taker. In addition to summarizing the literature regarding diagnostic research as opposed to scoring research, this study proposes a methodology for analyzing test results and compares the findings with those from the research of Bire… more

Increasing Telecommunications Channel Capacity: Impacts on Firm Profitability

Description: In calling for the deployment of high-capacity telecommunications infrastructures, the Clinton Administration is relying on market forces to drive demand toward self-sustaining development. There is little doubt that many firms will embrace the new telecommunications services for a variety of reasons including market differentiation, vertical market integration, and other organization-specific factors. However, there is little evidence at the firm level that adopting the use of increased-capaci… more

Identification of Remote Leadership Patterns in Academic and Public Libraries

Description: Seminal works on leadership, including those in librarianship define a traditional model of interaction between leaders and followers without reference to the information technology-driven environment. In addition, remote leadership indicates a different model from the traditional model, one that is focused on the interaction of leaders and their staff through digital technology. Although leaders still use face-to-face interaction, due to varied work schedules or job responsibilities, they also… more

Toward an Ideal Library: A Synthesis of Wilson's Library and Information Policy and Gilbert's Performance Matrix

Description: Inquiry about ideal library was sought by interdisciplinary approach from human competence derived from performance engineering by Gilbert (1978), and the library information policy by Wilson (1977). With Wilson's insights into the field of library and information science (LIS), this work demonstrated the synthesis of Wilson and Gilbert: engineering as common ground. One of the central concerns in LIS, utilization of knowledge, is re-conceptualized as Gilbert's view of performance, which refle… more

A mechanism for richer representation of videos for children: Calibrating calculated entropy to perceived entropy

Description: This study explores the use of the information theory entropy equation in representations of videos for children. The calculated rates of information in the videos are calibrated to the corresponding perceived rates of information as elicited from the twelve 7 to 10 year old girls who were shown video documents. Entropy measures are calculated for several video elements: set time, set incidence, verbal time, verbal incidence, set constraint, nonverbal dependence, and character appearance. As hy… more

Constraints on Adoption of Innovations: Internet Availability in the Developing World.

Description: In a world that is increasingly united in time and distance, I examine why the world is increasingly divided socially, economically, and digitally. Using data for 35 variables from 93 countries, I separate the countries into groups of 31 each by gross domestic product per capita. These groups of developed, lesser developed and least developed countries are used in comparative analysis. Through a review of relevant literature and tests of bivariate correlation, I select eight key variables that … more

News photography image retrieval practices: Locus of control in two contexts.

Description: This is the first known study to explore the image retrieval preferences of news photographers and news photo editors in work contexts. Survey participants (n=102) provided opinions regarding 11 photograph searching methods. The quantitative survey data were analyzed using descriptive statistics, while content analysis was used to evaluate the qualitative survey data. In addition, news photographers and news photo editors (n=11) participated in interviews. Data from the interviews were analyzed… more

Quality Management in Museum Information Systems: A Case Study of ISO 9001-2000 as an Evaluative Technique

Description: Museums are service-oriented information systems that provide access to information bearing materials contained in the museum's collections. Within museum environments, the primary vehicle for quality assurance and public accountability is the accreditation process of the American Association of Museums (AAM). Norbert Wiener founded the field of cybernetics, employing concepts of information feedback as a mechanism for system modification and control. W. Edwards Deming applied Wiener's principl… more

Privacy Concerns and Personality Traits Influencing Online Behavior: A Structural Model

Description: The concept of privacy has proven difficult to analyze because of its subjective nature and susceptibility to psychological and contextual influences. This study challenges the concept of privacy as a valid construct for addressing individuals' concerns regarding online disclosure of personal information, based on the premise that underlying behavioral traits offer a more reliable and temporally stable measure of privacy-oriented behavior than do snapshots of environmentally induced emotional s… more

The population studied was international students using resources in a community college. Library anxiety among international students begins with certain barriers that cause anxiety (i.e., language/communication barriers, adjusting to a new education/library system and general cultural adjustments). Library Anxiety is common among college student… more

Computer Support Interactions: Verifying a Process Model of Problem Trajectory in an Information Technology Support Environment.

Description: Observations in the information technology (IT) support environment and generalizations from the literature regarding problem resolution behavior indicate that computer support staff seldom store reusable solution information effectively for IT problems. A comprehensive model of the processes encompassing problem arrival and assessment, expertise selection, problem resolution, and solution recording has not been available to facilitate research in this domain. This investigation employed the fi… more

Improving Recall of Browsing Sets in Image Retrieval from a Semiotics Perspective

Description: The purpose of dissertation is to utilize connotative messages for enhancing image retrieval and browsing. By adopting semiotics as a theoretical tool, this study explores problems of image retrieval and proposes an image retrieval model. The semiotics approach conceptually demonstrates that: 1) a fundamental reason for the dissonance between retrieved images and user needs is representation of connotative messages, and 2) the image retrieval model which makes use of denotative index terms is a… more
