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 ...

Attitudes Toward the Contemporary Role of the Library Media Specialist in the Overall Elementary School Program in North Central Texas

Date: December 1989
Creator: Roach, Catharyn
Description: The purpose of this study, in addition to measuring and comparing attitudes of teachers, principals and library media specialists toward the role of the school library media specialist, was to identify and measure factors contributing to those attitudes. Nine factors were identified. Further path analysis revealed that the performance level of the library media specialist had the most influence on principals' and teachers' attitudes toward the Consultant, Technological and Instructional Roles. For principals and teachers, staff development had the most influence on attitudes toward the Management Role, while involvement in the school-wide program was most influential for library media specialists.

Factors Influencing Older Adults' Patterns of Information Acquisition

Factors Influencing Older Adults' Patterns of Information Acquisition

Date: May 1989
Creator: Barnett, Mary Jane, 1952-
Description: A group of 101 older adults (sixty-five years of age and over) who lived independently in three retirement apartment residences in Denton, Texas, were asked about their patterns of reading, television viewing, and radio listening habits for two periods in their lives: (1) at age forty to fifty-five and (2) at the present. Respondents were asked about their use of external information sources (public library, grocery store, newsstand, etc.) and their use of proximate information sources (radio, friends/relatives, television, etc.) They were also asked about access to transportation, income satisfaction, status of general health, vision, hearing, physical mobility and reasons for utilizing various information sources. Four hypotheses relating changes in health, environment, economic status, and education to reasons for reading and use of information sources were tested through the use of t-tests, regression analysis and analysis of variance. Within this group of older adults, use of external information sources decreased from the past to the present. There was, however, no change in the use of information sources located in or near the residence as difficulties in these areas increased. A relationship was found between educational level and reading for pleasure earlier in life. Also, those with higher educational levels reported ...

Factors Related to Mississippi School Library Media Centers in Multitype Cooperation

Factors Related to Mississippi School Library Media Centers in Multitype Cooperation

Date: May 1988
Creator: Partridge, Margaret
Description: The main purpose of this study was to identify the major obstacles to cooperation as perceived by school library media specialists in the state of Mississippi and to determine if members of the Coastal Mississippi Library Cooperative (CMLC) believe that there are fewer obstacles to cooperation than do non-members. The secondary purpose was to evaluate the CMLC to some extent to determine if success was achieved through organization when defined by the variables, planning, governance, funding, communication, administration, and evaluation. The population of the study was all of the librarians (academic, public, school, and special) in the six-county area which comprises the CMLC, and a random sample of public school librarians throughout the remainder of the state. All of the school librarians were sent a questionnaire that requested their responses to statements of barriers to cooperation. All of the librarians in the CMLC region were sent a questionnaire to obtain their perceptions of participation in the CMLC. Pour librarians, members of the CMLC, were Interviewed to obtain information on the organizational factors of the CMLC. Data received from school library media specialists were submitted to various statistical tests. The Chi-Square statistic was used on the demographic portion of the questionnaire, ...

Factors Related to the Professional Progress of Academic Librarians in Louisiana

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.

Selected Factors Associated With Reading Interests of Seventh- and Eighth-grade Pupils

Selected Factors Associated With Reading Interests of Seventh- and Eighth-grade Pupils

Date: May 1984
Creator: Newman, Nancy Ann
Description: This study sought to determine if there were differences in the types of reading interests of seventh- and eighth-grade pupils associated with their racial origins, their socioeconomic status, or their school environments. It also sought to consider the strength of reading interest scores as related to other variables and to consider the relationship between these scores and the number of hours spent in reading and the change in amount of reading since the previous school year.

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.
