The Online and the Onsite Holocaust Museum Exhibition as an Informational Resource

Museums today provide learning-rich experiences and quality informational resources through both physical and virtual environments. This study examined a Holocaust Museum traveling exhibition, Life in Shadows: Hidden Children and the Holocaust that was on display at the Art Center of Battle Creek, Michigan in fall 2005. The purpose of this mixed methods study was to assess the informational value of a Holocaust Museum exhibition in its onsite vs. online format by converging quantitative and qualitative data. Participants in the study included six eighth grade language arts classes who viewed various combinations or scenarios of the onsite and online Life in Shadows. Using student responses to questions in an online exhibition survey, an analysis of variance was performed to determine which scenario visit promotes the greatest content learning. Using student responses to additional questions on the same survey, data were analyzed qualitatively to discover the impact on students of each scenario visit. By means of an emotional empathy test, data were analyzed to determine differences among student response according to scenario visit. A principal finding of the study (supporting Falk and Dierking's contextual model of learning) was that the use of the online exhibition provided a source of prior orientation and …

Knowledge management in times of change: Tacit and explicit knowledge transfers. (open access)

Knowledge management in times of change: Tacit and explicit knowledge transfers.

This study proposed a look at the importance and challenges of knowledge management in times of great change. In order to understand the information phenomena of interest, impacts on knowledge workers and knowledge documents in times of great organizational change, the study is positioned in a major consolidation of state agencies in Texas. It pays special attention to how the changes were perceived by the knowledge workers by interviewing those that were impacted by the changes resulting from the reorganization. The overall goal is to assess knowledge management in times of great organizational change by analyzing the impact of consolidation on knowledge management in Texas's Health and Human Services agencies. The overarching research question is what happened to the knowledge management structure during this time of great change? The first research question was what was the knowledge worker environment during the time of change? The second research question was what was the knowledge management environment of the agencies during the time of change? The last research question was did consolidation of the HHS agencies diminish the ability to transition from tacit to explicit knowledge? Additionally, the study investigates how the bill that mandated the consolidation was covered in the local …

A Common Representation Format for Multimedia Documents (open access)

A Common Representation Format for Multimedia Documents

Multimedia documents are composed of multiple file format combinations, such as image and text, image and sound, or image, text and sound. The type of multimedia document determines the form of analysis for knowledge architecture design and retrieval methods. Over the last few decades, theories of text analysis have been proposed and applied effectively. In recent years, theories of image and sound analysis have been proposed to work with text retrieval systems and progressed quickly due in part to rapid progress in computer processing speed. Retrieval of multimedia documents formerly was divided into the categories of image and text, and image and sound. While standard retrieval process begins from text only, methods are developing that allow the retrieval process to be accomplished simultaneously using text and image. Although image processing for feature extraction and text processing for term extractions are well understood, there are no prior methods that can combine these two features into a single data structure. This dissertation will introduce a common representation format for multimedia documents (CRFMD) composed of both images and text. For image and text analysis, two techniques are used: the Lorenz Information Measurement and the Word Code. A new process named Jeong's Transform is …

An Analysis of Factors in the Adoption or Non-Adoption of Videodisc Technology in North American Academic and Special Libraries (open access)

An Analysis of Factors in the Adoption or Non-Adoption of Videodisc Technology in North American Academic and Special Libraries

The researcher identified 37 independent variables to study their effect on the two dependent variables, the acquisition of videodiscs and the functions for which videodisc programs were acquired. The literature of the applications of videodisc technology in libraries, museums, education and industry, as well as related issues concerning interactive video, were presented in Chapter 2. Using the diffusion of innovation theory of Everett Rogers as a guide, the researcher constructed a questionnaire. Valid responses totaled 462 from management of all types of academic libraries and from special libraries other than non-academic law, military, veterans' hospital, and church libraries. The following conclusions were made from the results: there were significant correlations between having videodiscs and perceptions of greater benefits than costs, appropriateness of videodisc programs for libraries' objectives or curricula, seeing videodiscs as an enhancement of an existing library technology, collection of videocassettes, and ability to raise funds from slack resources. The size of the libraries' materials and equipment budgets had some significance, but it was not consistently significant, as it was for the above-mentioned factors, at the p < .01 level. Lack of in-house recording ability did not impose a barrier on adoption of discs among respondents. Full--motion, full-screen video …

A multi-dimensional entropy model of jazz improvisation for music information retrieval. (open access)

A multi-dimensional entropy model of jazz improvisation for music information retrieval.

Jazz improvisation provides a case context for examining information in music; entropy provides a means for representing music for retrieval. Entropy measures are shown to distinguish between different improvisations on the same theme, thus demonstrating their potential for representing jazz information for analysis and retrieval. The calculated entropy measures are calibrated against human representation by means of a case study of an advanced jazz improvisation course, in which synonyms for "entropy" are frequently used by the instructor. The data sets are examined for insights in music information retrieval, music information behavior, and music representation.

Information Needs of Art Museum Visitors: Real and Virtual (open access)

Information Needs of Art Museum Visitors: Real and Virtual

Museums and libraries are considered large repositories of human knowledge and human culture. They have similar missions and goals in distributing accumulated knowledge to society. Current digitization projects allow both, museums and libraries to reach a broader audience, share their resources with a variety of users. While studies of information seeking behavior, retrieval systems and metadata in library science have a long history; such research studies in museum environments are at their early experimental stage. There are few studies concerning information seeking behavior and needs of virtual museum visitors, especially with the use of images in the museums' collections available on the Web. The current study identifies preferences of a variety of user groups about the information specifics on current exhibits, museum collections metadata information, and the use of multimedia. The study of information seeking behavior of users groups of museum digital collections or cultural collections allows examination and analysis of users' information needs, and the organization of cultural information, including descriptive metadata and the quantity of information that may be required. In addition, the study delineates information needs that different categories of users may have in common: teachers in high schools, students in colleges and universities, museum professionals, art …

Korean Studies in North America 1977-1996: A Bibliometric Study

This research is a descriptive bibliometric study of the literature of the field of Korean studies. Its goal is to quantitatively describe the literature and serve as a model for such research in other area studies fields. This study analyzed 193 source articles and 7,166 citations in the articles in four representative Korean and Asian studies journals published in North America from 1977 to 1996. The journals included in this study were Korean Studies (KS), the Journal of Korean Studies (JKS), the Journal of Asian Studies (JAS), and the Harvard Journal of Asiatic Studies (HJAS). Subject matters and author characteristics of the source articles were examined, along with various characteristics such as the form, date, language, country of origin, subject, key authors, and key titles of the literature cited in the source articles. Research in Korean studies falls within fourteen broad disciplines, but concentrated in a few disciplines. Americans have been the most active authors in Korean studies, followed closely by authors of Korean ethnicity. Monographic literature was used most. The mean age of publications cited was 20.87 and the median age of publications cited was 12. The Price Index of Korean studies as a whole is 21.9 percent. Sources …

Knowledge synthesis in the biomedical literature: Nordihydroguaiaretic acid and breast cancer. (open access)

Knowledge synthesis in the biomedical literature: Nordihydroguaiaretic acid and breast cancer.

This dissertation refines knowledge synthesis from publicly accessible databases, based on the model of D.R. Swanson. Knowledge synthesis endeavors bring together two or more non-interactive literatures to create combinatorial research data on a specific topic. In this endeavor the biomedical literature was searched on the anti-neoplastic agent nordihydroguaiaretic acid (NDGA) for its potential role as a functional food in the chemoprevention of breast cancer. Bibliometric cocitation was utilized to identify complementary but non-interactive literatures in the disciplines of biomedicine and dietary science. The continuing specialization and fragmentation of the cancer literature degenerates the potential usefulness of cross-disciplinary research and information. As the biomedical sciences become more specialized the potential increases for isolation of discoveries and for failures to connect science to the needs of the people. Within the information science discipline several techniques are available to bridge the isolation between discoveries recorded in different sets of literatures. Electronic database searching with combinatorial keyword entries, syllogistic modeling and bibliometric author cocitation analysis are the principle techniques applied in this endeavor. The research questions are addressed to the absence or presence of human in vivo research on breast cancer with the potentially chemopreventative functional food NDGA. Utilizing a syllogistic model the literatures …

The Relationship Between Work Roles and Information Seeking Behaviors Among Selected Protestant Ministers in Tarrant County, Texas (open access)

The Relationship Between Work Roles and Information Seeking Behaviors Among Selected Protestant Ministers in Tarrant County, Texas

Is there a relationship between work role and information seeking behavior? Three behaviors were examined: choice of information channel, choice of method for information retrieval, and choice of method for storing retrieved information. The Protestant clergy was selected as a profession with clearly identified work roles, including preacher and administrator. Questionnaires were mailed to 150 randomly selected ministers in Tarrant County, Texas. Sixty-four responded. Additionally, fifteen ministers selected at random were interviewed for additional data. The data collected through the questionnaires were analyzed using nonparametric statistical techniques.

Sanctioned and Controlled Message Propagation in a Restrictive Information Environment: The Small World of Clandestine Radio Broadcasting (open access)

Sanctioned and Controlled Message Propagation in a Restrictive Information Environment: The Small World of Clandestine Radio Broadcasting

This dissertation seeks to identify the elements that inform the model for competing message propagation systems in a restrictive environment. It pays attention to message propagation by sanctioned and clandestine radio stations in pre- and post-independent Zimbabwe. This dissertation uses two models of message propagation in a limiting information environment: Sturges' information model of national liberation struggle and Chatman's small world information model. All the message propagation elements in the Sturges and Chatman's models are present in the broadcast texts analyzed. However, the findings of this dissertation indicate that communication in a restrictive information environment is designed such that its participants make sense of their situation, and come up with ways to solve the challenges of their small world. Also, a restrictive information environment is situational, and message propagators operating in it are subject to tactical changes at different times, accordingly altering their cognitive maps. The two models fail to address these concerns. This dissertation focused on message propagation in Zimbabwe because there is military belligerence involved in the information warfare. It therefore provides an extreme situation, which can help our understanding of more everyday instances of communication and interference of communication. Findings of this dissertation recommend the need to …

Formalization of Collection Development in Selected Medium-Sized Academic Libraries (open access)

Formalization of Collection Development in Selected Medium-Sized Academic Libraries

The degree of formalization of collection development(the dependent variable) in selected medium-sized academic libraries and six independent variables believed to be related to the dependent variable were examined. The formalization of collection development was measured by an index of five dimensions. The six independent variables examined were age of the library, number of graduate degrees offered by the parent institution, estimated years of growth potential in terms of available shelf space, attitude of the library director toward cooperation, number of memberships held by the library in cooperative endeavors, and percentage of increase in the materials budget, from 1972 to 1982. The findings of this study fail to support hypotheses one, three, four, and six. The relationship between the number of memberships in cooperative endeavors (hypothesis five) is weak, but significant. Hypothesis two is not supported when the total group is considered, but it is supported only when publicly-supported libraries are considered. A positive relationship between size of collection and level of collection development formalization was found to be significant, as was the relationship between number of graduate degrees and size of collection.

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

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

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 findings from a qualitative pilot study of IT support staff information behaviors to develop and explicate a detailed model of problem trajectory. Based on a model from clinical studies, this model encompassed a trajectory scheme that included the communication media, characteristics of the problem, decision points in the problem resolution process, and knowledge creation in the form of solution storage. The research design included the administration of an extensive scenario-based online survey to a purposive sample of IT support staff at a medium-sized state-supported university, with additional respondents from online communities of IT support managers and call-tracking software developers. The investigator analyzed 109 completed surveys and conducted email interviews of a stratified nonrandom sample of survey respondents to evaluate the suitability of the model. The investigation employed mixed methods including descriptive statistics, effects size analysis, and content …
