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

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

Date: August 1997
Creator: Goodrum, Abby A. (Abby Ann)
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 different types of representations. Such basic research has the potential to inform IR system designers about how best to aid users of their systems in retrieving moving images. One key requirement for the effective use of document representations in either textual or image form is thedegree to which these representations are congruent with the original documents. A measure of congruence is the degree to which human responses to representations are similar to responses produced by the document being represented. The aim of this study was to develop a model for the representation of moving images based upon human judgements of representativeness. The study measured the degree of congruence between moving image documents and their representations, both text and image based, in a non-retrieval environment with and without task ...

Elementary School Climate Factors and Personality and Status Variables Associated with School Library Media Specialists Chosen by Classroom Teachers for Cooperation on Instructional Problems

Elementary School Climate Factors and Personality and Status Variables Associated with School Library Media Specialists Chosen by Classroom Teachers for Cooperation on Instructional Problems

Date: December 1990
Creator: Bell, Michael David, 1943-
Description: This study investigated relationships between the extent to which elementary classroom teachers tend to choose school library media specialists for cooperation on instructional problems and several school climate and faculty related characteristics including the general academic effectiveness of the school, the overall cohesion and cooperativeness of the teaching faculty on instructional matters, and the propensity of the group and individual faculty to seek cooperation to solve instructional problems. The instructional choice status of the school library media specialist was also studied in relation to various individual personality factors, as measured by Cattell's 16 Personality Factor Questionnaire, as well as school media specialist status variables including degreed or non-degreed status, total years of experience as a school library media specialist, years of experience on campus as a school library media specialist, and total number of years of experience in the field of education. The instructional status of the school library media specialist was also examined in relationship to the size of the school served. The study included 1,079 elementary classroom teachers and thirty-nine school library media specialists from thirty-nine Texas elementary schools similar in important wealth, size, and student demographic characteristics. Twenty of the schools ranked in the bottom 25% of ...

An Examination of Selected Product Characteristics Associated with the Sales Success of Nontheatrical Film and Video Works

An Examination of Selected Product Characteristics Associated with the Sales Success of Nontheatrical Film and Video Works

Date: May 1990
Creator: Munde, Gail Marie
Description: The purpose of this study was to test assumptions made about characteristics of nontheatrical film and video works that were thought to contribute to the frequency with which the works were purchased. This study proposed and tested three variables for which relationships to the sales success of nontheatrical film and video works were hypothesized, as well as four variables about which no hypotheses were forwarded. Nineteen film and video distribution organizations contributed unit sales data for the period 1982-1987 on 151 works copyrighted between 1982 and 1984. These data were analyzed for relationships between sales totals and 1) curricular significance of the works' subjects, 2) relevance to general reading interest in the works' subjects, 3) intensity of competition faced by the works, 4) the works' Dewey classifications as compared to the composition of typical K-12 school library book collections, 5) the series or non-series status of the works, 6) the media format(s) in which the works were available for purchase and 7) the sources of the works' production financing. Analyses of correlation and association were performed and no significant relationships were found between sales and curricular significance of the works' subjects, or their relevance to general reading interest. Some evidence ...

Factors Related to the Professional Progress of Academic Librarians in Louisiana

Date: May 1991
Creator: Brazile, Orella Ramsey, 1945-
Description: Three groups of Academic librarians in Louisiana were surveyed to determine what factors other than job performance influenced professional progress (Salary increases, promotion and tenure) for them. Staff development activities were also investigated to determine if they played any significant role in influencing professional progress. Three opinion questions were also asked in this investigation about the feasibility of using an index that was developed to assess quantitatively staff development activities.

Diagnosing Learner Deficiencies in Algorithmic Reasoning

Diagnosing Learner Deficiencies in Algorithmic Reasoning

Date: May 1995
Creator: Hubbard, George U.
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 Birenbaum and Tatsuoka and others. The proposed method identifies the conditions of misinformation and missing information, and it contains a statistical compensation for careless errors. Strengths and weaknesses of the method are explored, and suggestions for further research are offered.

Increasing Telecommunications Channel Capacity: Impacts on Firm Profitability

Increasing Telecommunications Channel Capacity: Impacts on Firm Profitability

Date: August 1997
Creator: Clower, Terry L.
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-capacity telecommunications technologies is associated with improvements in firm profitability. This study seeks to identify the presence of impacts on firm income that can be associated with the adoption of T1 telecommunications services.

Managerial Style and the Use of Statistical Data in Techincal Services Units in Selected Academic Libraries

Managerial Style and the Use of Statistical Data in Techincal Services Units in Selected Academic Libraries

Date: December 1992
Creator: Karpuk, Deborah J.
Description: The primary purpose of this study was to test the following hypothesis: The internal use (use within the technical services unit for decision making and planning) of statistical data will be significantly higher for managers scoring in the Sensing-Thinking (ST) scale of the self-assessment instrument Myers-Briggs Type Indicator. A Technical Services Statistics Survey Form was developed in order to collect statistical data from the technical services managers participating in the study. The Myers-Briggs Type Indicator was utilized to record managers' personal management style. Thirty-two managers participated in the two-part study. The hypothesis of the study was not supported because no significant differences in the predicted direction were found to exist between the use of the technical services statistics and management style groups as measured by the Myers-Briggs Type Indicator. (A Mann-Whitney U Test was used due to the small, uneven sample size.) There were significant differences between Sensing-Thinking (ST) and Intuitive-Feeling (NF) types, but not in the direction predicted by the hypothesis. Possible explanations for this unexpected finding include the very small sample size, the larger percentage of male respondents in the NF type, and the larger percentage of respondents from smaller institutions in the NF type. (Gender and institutional ...
