Factors Influencing How Students Value Asynchronous Web Based Courses

Description: This dissertation discovered the factors influencing how students value asynchronous Web-based courses through the use of qualitative methods. Data was collected through surveys, observations, interviews, email correspondence, chat room and bulletin board transcripts. Instruments were tested in pilot studies of previous semesters. Factors were identified for two class formats. The asynchronous CD/Internet class format and the synchronous online Web based class format. Also, factors were uncovered for two of the instructional tools used in the course: the WebCT forum and WebCT testing. Factors were grouped accordingly as advantages or disadvantages under major categories. For the asynchronous CD/Internet class format the advantages were Convenience, Flexibility, Learning Enhancement, and Psychology. The disadvantages included Isolation, Learning Environment, and Technology. For the synchronous online Web based class format the advantages were Convenience, Flexibility, Human Interaction, Learning Enhancement and Psychology, whereas the disadvantages included Isolation, Learning Environment and Technology. Concurrently, the study revealed the following factors as advantages of the WebCT Forum: Help Each Other, Interaction, Socialization, Classroom News, and Time Independent. The disadvantages uncovered were Complaints, Technical Problems and Isolation. Finally, advantages specified for the WebCT testing tool were Convenience, Flexibility and Innovations, and its disadvantages were Surroundings Not Conducive to Learning, and Technical Problems. Results indicate that not only classroom preference, learning style and personality type influence how students value a Web based course, but, most importantly, a student's lifestyle (number of personal commitments, how far they live, and life's priorities). The WebCT forum or bulletin board, and the WebCT testing or computerized testing were seen mostly by students, as good tools for encouraging classroom communication and testing because of the convenience and flexibility offered. Still, further research is needed both quantitatively and qualitatively to ascertain the true weight of the factors discovered in this study.

Factors Influencing Older Adults' Patterns of Information Acquisition

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 fewer differences in their reasons for reading in the present and in the past.

Factors Related to Mississippi School Library Media Centers in Multitype Cooperation

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, which revealed that four of the variables and the dependent variable, membership in the CMLC, were significantly different. A t-test performed on the barriers to cooperation section produced no significant differences between the member and non-member responses. The perceptions of participation in the CMLC data revealed that there were differences among the four library systems (academic, public, school, and special) involved, but most of the respondents considered the CMLC to be successful. Data from the interview also revealed that the CMLC was successful in its organization. Due to the overall low response to the survey, the stated hypotheses could not ...

A Framework of Automatic Subject Term Assignment: An Indexing Conception-Based Approach

Description: The purpose of dissertation is to examine whether the understandings of subject indexing processes conducted by human indexers have a positive impact on the effectiveness of automatic subject term assignment through text categorization (TC). More specifically, human indexers' subject indexing approaches or conceptions in conjunction with semantic sources were explored in the context of a typical scientific journal article data set. Based on the premise that subject indexing approaches or conceptions with semantic sources are important for automatic subject term assignment through TC, this study proposed an indexing conception-based framework. For the purpose of this study, three hypotheses were tested: 1) the effectiveness of semantic sources, 2) the effectiveness of an indexing conception-based framework, and 3) the effectiveness of each of three indexing conception-based approaches (the content-oriented, the document-oriented, and the domain-oriented approaches). The experiments were conducted using a support vector machine implementation in WEKA (Witten, & Frank, 2000). The experiment results pointed out that cited works, source title, and title were as effective as the full text, while keyword was found more effective than the full text. In addition, the findings showed that an indexing conception-based framework was more effective than the full text. Especially, the content-oriented and the document-oriented indexing approaches were found more effective than the full text. Among three indexing conception-based approaches, the content-oriented approach and the document-oriented approach were more effective than the domain-oriented approach. In other words, in the context of a typical scientific journal article data set, the objective contents and authors' intentions were more focused that the possible users' needs. The research findings of this study support that incorporation of human indexers' indexing approaches or conception in conjunction with semantic sources has a positive impact on the effectiveness of automatic subject term assignment.

Functional Ontology Construction: A Pragmatic Approach to Addressing Problems Concerning the Individual and the Informing Environment

Description: Functional ontology construction (FOC) is an approach for modeling the relationships between a user and the informing environment by means of analysis of the user's behavior and the elements of the environment that have behavioral function. The FOC approach is an application of behavior analytic techniques and concepts to problems within information science. The FOC approach is both an alternative and a compliment to the cognitive viewpoint commonly found in models of behavior in information science. The basis for the synthesis of behavior analysis and information science is a shared tradition of pragmatism between the fields. The application of behavior analytic concepts brings with it the notion of selection by consequence. Selection is examined on the biological, behavioral, and cultural levels. Two perspicuous examples of the application of the FOC modeling approach are included. The first example looks at the document functioning as a reinforcer in a human operant experimental setting. The second example is an examination of the verbal behavior of expert film analyst, Raymond Bellour, the structure of a film he analyzed, and the elements of the film's structure that had behavioral function for Bellour. The FOC approach is examined within the ontological space of information science.

The gathering and use of information by fifth grade students with access to Palm® handhelds.

Description: Handheld computers may hold the possibility for a one-to-one computer: student ratio. The impact of the use of Palm® (Palm, Inc.) handhelds on information acquisition and use by 5th grade students in a North Texas school during a class research project was investigated. Five research questions were examined using observation, interviews, surveys, and document analysis. Are there differences in information gathering and use with the Palm between gifted, dyslexic, and regular learners? What relevance criteria do students use to evaluate a web site to determine whether to download the site to the Palm and afterwards whether to use the downloaded site's information in the report? How do the Palms affect the writing process? Do the animations and concept maps produced on the Palm demonstrate understanding of the intended concepts? Are there significant differences in results (i.e., final products grade) between Palm users and non-Palm users? Three groups of learners in the class, gifted, dyslexic, and regular learners, participated in the study. The regular and dyslexic students reported using Web sites that had not been downloaded to the Palm. Students reported several factors used to decide whether to download Web sites, but the predominant deciding factor was the amount of information. The students used a combination of writing on paper and the Palm in the preparation of the report. Many students flipped between two programs, FreeWrite and Fling-It, finding information and then writing the facts into the report. The peer review process was more difficult with the Palm. Most students had more grammatical errors in this research report than in previous research projects. By creating animated drawings on the Palm handheld, the students demonstrated their understanding of the invention though sometimes the media or the student's drawing skills limited the quality of the final product. Creating the animations was motivational and ...

Global response to cyberterrorism and cybercrime: A matrix for international cooperation and vulnerability assessment.

Description: Cyberterrorism and cybercrime present new challenges for law enforcement and policy makers. Due to its transnational nature, a real and sound response to such a threat requires international cooperation involving participation of all concerned parties in the international community. However, vulnerability emerges from increased reliance on technology, lack of legal measures, and lack of cooperation at the national and international level represents real obstacle toward effective response to these threats. In sum, lack of global consensus in terms of responding to cyberterrorism and cybercrime is the general problem. Terrorists and cyber criminals will exploit vulnerabilities, including technical, legal, political, and cultural. Such a broad range of vulnerabilities can be dealt with by comprehensive cooperation which requires efforts both at the national and international level. "Vulnerability-Comprehensive Cooperation-Freedom Scale" or "Ozeren Scale" identified variables that constructed the scale based on the expert opinions. Also, the study presented typology of cyberterrorism, which involves three general classifications of cyberterrorism; Disruptive and destructive information attacks, Facilitation of technology to support the ideology, and Communication, Fund raising, Recruitment, Propaganda (C-F-R-P). Such a typology is expected to help those who are in a position of decision-making and investigating activities as well as academicians in the area of terrorism. The matrix for international cooperation and vulnerability assessment is expected to be used as a model for global response to cyberterrorism and cybercrime.

Human concept cognition and semantic relations in the unified medical language system: A coherence analysis.

Description: There is almost a universal agreement among scholars in information retrieval (IR) research that knowledge representation needs improvement. As core component of an IR system, improvement of the knowledge representation system has so far involved manipulation of this component based on principles such as vector space, probabilistic approach, inference network, and language modeling, yet the required improvement is still far from fruition. One promising approach that is highly touted to offer a potential solution exists in the cognitive paradigm, where knowledge representation practice should involve, or start from, modeling the human conceptual system. This study based on two related cognitive theories: the theory-based approach to concept representation and the psychological theory of semantic relations, ventured to explore the connection between the human conceptual model and the knowledge representation model (represented by samples of concepts and relations from the unified medical language system, UMLS). Guided by these cognitive theories and based on related and appropriate data-analytic tools, such as nonmetric multidimensional scaling, hierarchical clustering, and content analysis, this study aimed to conduct an exploratory investigation to answer four related questions. Divided into two groups, a total of 89 research participants took part in two sets of cognitive tasks. The first group (49 participants) sorted 60 food names into categories followed by simultaneous description of the derived categories to explain the rationale for category judgment. The second group (40 participants) performed sorting 47 semantic relations (the nonhierarchical associative types) into 5 categories known a priori. Three datasets resulted as a result of the cognitive tasks: food-sorting data, relation-sorting data, and free and unstructured text of category descriptions. Using the data analytic tools mentioned, data analysis was carried out and important results and findings were obtained that offer plausible explanations to the 4 research questions. Major results include the following: (a) through discriminant ...

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 recognize the need to lead employees remotely. Leadership studies in library literature have not addressed how library leaders use information technology to lead employees remotely, nor have these studies addressed remote leadership and remote employees, except for some articles on telecommuting. As a result, this research was conducted to address this gap, providing an exploratory foundation of emergent patterns of remote leadership with its associated leadership dimensions rooted in personality traits, behaviors, and skills. Quantitative and qualitative data were obtained from a small sample size of academic and public-library leaders in the United States who participated in a Web-based survey designed specifically for this study, limiting generalizations. Factor analysis was the principal methodology used to obtain findings. Its composite factor scores were also used in the t-test and chi-square analyses. This study identifies some emergent patterns of remote leadership in the library and information-science field, exploring whether library leaders use information technology to be effective remote leaders in a technology-driven environment, and whether existing leadership attributes could be identified as part of the remote-leadership model. Because this study's findings indicated that library leaders are not quite the traditional leader but are not fully integrated into remote leadership, it becomes apparent that they would function with a blend of both face-to-face and electronic interactions, due to the nature of library work. Additionally, this research revealed underlying issues and challenges faced by library leaders ...

Identifying At-Risk Students: An Assessment Instrument for Distributed Learning Courses in Higher Education

Description: The current period of rapid technological change, particularly in the area of mediated communication, has combined with new philosophies of education and market forces to bring upheaval to the realm of higher education. Technical capabilities exceed our knowledge of whether expenditures on hardware and software lead to corresponding gains in student learning. Educators do not yet possess sophisticated assessments of what we may be gaining or losing as we widen the scope of distributed learning. The purpose of this study was not to draw sweeping conclusions with respect to the costs or benefits of technology in education. The researcher focused on a single issue involved in educational quality: assessing the ability of a student to complete a course. Previous research in this area indicates that attrition rates are often higher in distributed learning environments. Educators and students may benefit from a reliable instrument to identify those students who may encounter difficulty in these learning situations. This study is aligned with research focused on the individual engaged in seeking information, assisted or hindered by the capabilities of the computer information systems that create and provide access to information. Specifically, the study focused on the indicators of completion for students enrolled in video conferencing and Web-based courses. In the final version, the Distributed Learning Survey encompassed thirteen indicators of completion. The results of this study of 396 students indicated that the Distributed Learning Survey represented a reliable and valid instrument for identifying at-risk students in video conferencing and Web-based courses where the student population is similar to the study participants. Educational level, GPA, credit hours taken in the semester, study environment, motivation, computer confidence, and the number of previous distributed learning courses accounted for most of the predictive power in the discriminant function based on student scores from the survey.

The Impact of Predisposition Towards Group Work on Intention to Use a CSCW System

Description: Groupware packages are increasingly being used to support content delivery, class discussion, student to student and student to faculty interactions and group work on projects. This research focused on groupware packages that are used to support students who are located in different places, but who are assigned group projects as part of their coursework requirements. In many cases, students are being asked to use unfamiliar technologies that are very different from those that support personal productivity. For example, computer-assisted cooperative work (CSCW) technology is different from other more traditional, stand-alone software applications because it requires the user to interact with the computer as well as other users. However, familiarity with the technology is not the only requirement for successful completion of a group assigned project. For a group to be successful, it must also have a desire to work together on the project. If this pre-requisite is not present within the group, then the technology will only create additional communication and coordination barriers. How much of an impact does each of these factors have on the acceptance of CSCW technology? The significance of this study is threefold. First, this research contributed to how a user's predisposition toward group work affects their acceptance of CSCW technology. Second, it helped identify ways to overcome some of the obstacles associated with group work and the use of CSCW technology in an academic online environment. Finally, it helped identify early adopters of CSCW software and how these users can form the critical mass required to diffuse the technology. This dissertation reports the impact of predisposition toward group work and prior computer experience on the intention to use synchronous CSCW. It was found that predisposition toward group work was not only positively associated to perceived usefulness; it was also related to intention to use. It ...

Implications of the inclusion of document retrieval systems as actors in a social network.

Description: Traditionally, social network analysis (SNA) techniques enable the examination of relationships and the flow of information within networks of human members or groups of humans. This study extended traditional social network analysis to include a nonhuman group member, specifically a document retrieval system. The importance of document retrieval systems as information sources, the changes in business environments that necessitates the use of information and communication technologies, and the attempts to make computer systems more life-like, provide the reasons for considering the information system as a group member. The review of literature for this study does not encompass a single body of knowledge. Instead, several areas combined to inform this study, including social informatics for its consideration of the intersection of people and information technology, network theory and social network analysis, organizations and information, organizational culture, and finally, storytelling in organizations as a means of transferring information. The methodology included distribution of surveys to two small businesses that used the same document retrieval system, followed by semi-structured interviews of selected group members, which allowed elaboration on the survey findings. The group members rated each other and the system on four interaction criteria relating to four social networks of interest, including awareness, access, information flow, and problem solving. Traditional measures of social networks, specifically density, degree, reciprocity, transitivity, distance, degree centrality, and closeness centrality provided insight into the positioning of the nonhuman member within the social group. The human members of the group were able to respond to the survey that included the system but were not ready to consider the system as being equivalent to other human members. SNA measures positioned the system as an average member of the group, not a star, but not isolated either. Examination of the surveys or the interviews in isolation would not have given a ...

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 able to facilitate users to browse connotatively related images effectively even when the users' needs are potentially expressed in the form of denotative query. Two experiments are performed for verifying the semiotic-based image retrieval model and evaluating the effectiveness of the model. As data sources, 5,199 records are collected from Artefacts Canada: Humanities by Canadian Heritage Information Network, and the candidate terms of connotation and denotation are extracted from Art & Architecture Thesaurus. The first experiment, by applying term association measures, verifies that the connotative messages of an image can be derived from denotative messages of the image. The second experiment reveals that the association thesaurus which is constructed based on the associations between connotation and denotation facilitates assigning connotative terms to image documents. In addition, the result of relevant judgments presents that the association thesaurus improves the relative recall of retrieved image documents as well as the relative recall of browsing sets. This study concludes that the association thesaurus indicating associations between connotation and denotation is able to improve the accessibility of the connotative messages. The results of the study are hoped to contribute to the conceptual knowledge of image retrieval by providing understandings of connotative messages within an image and to the practical design of image retrieval system by proposing an association thesaurus which can supplement the limitations of the current content-based image retrieval systems ...

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-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.

The Information Environment of Academic Library Directors: Use of Information Resources and Communication Technologies

Description: This study focuses on the use of information resources and communication technologies, both traditional and electronic, by academic library directors. The purpose is to improve understanding of managerial behavior when using information resources and communication technologies within a shared information environment. Taylor's concept of an information use environment is used to capture the elements associated with information use and communication within the context of decision-making styles, managerial roles, organizational environments, and professional communities. This qualitative study uses interviews, observations, questionnaires, and documents. Library directors participating in the study are from doctoral-degree granting universities in the southwestern United States. Data collection involved on-site observations with a PDA (personal digital assistant), structured interviews with library directors and their administrative assistants, the Decision Style Inventory, and a questionnaire based on Mintzberg's managerial roles. Findings show the existence of a continuum in managerial activities between an Administrator and an Administrator/Academic as critical to understanding information use and communication patterns among library directors. There is a gap between self-perception of managerial activities and actual performance, a finding that would not have surfaced without the use of multiple methods. Other findings include the need for a technical ombudsman, a managerial-level position reporting to the library director; the importance of information management as an administrative responsibility; the importance of trust when evaluating information; and the importance of integrating information and communication across formats, time, and managerial activities.

Information Needs of Art Museum Visitors: Real and Virtual

Description: 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 historians and researchers, and the general public. This research also compares informational and educational needs of real visitors with the needs of virtual visitors. Educational needs of real visitors are based on various studies conducted and summarized by Falk and Dierking (2000), and an evaluation of the art museum websites previously conducted to support the current study.

Information Seeking in a Virtual Learning Environment

Description: Duplicating a time series study done by Kuhlthau and associates in 1989, this study examines the applicability of the Information Search Process (ISP) Model in the context of a virtual learning environment. This study confirms that students given an information seeking task in a virtual learning environment do exhibit the stages indicated by the ISP Model. The six-phase ISP Model is shown to be valid for describing the different stages of cognitive, affective, and physical tasks individuals progress through when facing a situation where they must search for information to complete an academic task in a virtual learning environment. The findings in this study further indicate there is no relationship between the amount of computer experience subjects possess and demonstrating the patterns of thoughts, feelings, and actions described by the ISP Model. The study demonstrates the ISP Model to be independent of the original physical library environments where the model was developed. An attempt is made to represent the ISP model in a slightly different manner that provides more of the sense of motion and interaction among the components of thoughts, feelings, and action than is currently provided for in the model. The study suggests that the development of non-self-reporting data collection techniques would be useful in complementing and furthering research to enhance and refine the representation of the ISP Model. Additionally, expanding the research to include the examination of group interaction is called for to enhance the ISP Model and develop further applications that could potentially aid educational delivery in all types of learning environments.

Information systems assessment: development of a comprehensive framework and contingency theory to assess the effectiveness of the information systems function.

Description: The purpose of this research is to develop a comprehensive, IS assessment framework using existing IS assessment theory as a base and incorporating suggestions from other disciplines. To validate the framework and to begin the investigation of current IS assessment practice, a survey instrument was developed. A small group of subject matter experts evaluated and improved the instrument. The instrument was further evaluated using a small sample of IS representatives. Results of this research include a reexamination of the IS function measurement problem using new frameworks of analyses yielding (a) guidance for the IS manager or executive on which IS measures might best fit their organization, (b) a further verification of the important measures most widely used by IS executives, (c) a comprehensive, theoretically-derived, IS assessment framework, and by (d) the enhancement of IS assessment theory by incorporating ideas from actual practice. The body of knowledge gains a comprehensive, IS assessment framework that can be further tested for usefulness and applicability. Future research is recommended to substantiate and improve on these findings. Chapter 2 is a complete survey of prior research, subdivided by relevant literature divisions, such as organizational effectiveness, quality management, and IS assessment. Chapter 3 includes development of and support for the research questions, IS assessment framework, and the research model. Chapter 4 describes how the research was conducted.

Intangible Qualities of Rare Books: Toward a Decision-Making Framework for Preservation Management in Rare Book Collections, Based Upon the Concept of the Book as Object

Description: For rare book collections, a considerable challenge is involved in evaluating collection materials in terms of their inherent value, which includes the textual and intangible information the materials provide for the collection's users. Preservation management in rare book collections is a complex and costly process. As digitization and other technological advances in surrogate technology have provided new forms representation, new dilemmas in weighing the rare book's inherently valuable characteristics against the possibly lesser financial costs of surrogates have arisen. No model has been in wide use to guide preservation management decisions. An initial iteration of such a model is developed, based on a Delphi-like iterative questioning of a group of experts in the field of rare books. The results are used to synthesize a preservation management framework for rare book collections, and a small-scale test of the framework has been completed through two independent analyses of five rare books in a functioning collection. Utilizing a standardized template for making preservation decisions offers a variety of benefits. Preservation decisions may include prioritizing action upon the authentic objects, or developing and maintaining surrogates in lieu of retaining costly original collection materials. The framework constructed in this study provides a method for reducing the subjectivity of preservation decision-making and facilitating the development of a standard of practice for preservation management within rare book collections.

The intersection of social networks in a public service model: A case study.

Description: Examining human interaction networks contributes to an understanding of factors that improve and constrain collaboration. This study examined multiple network levels of information exchanges within a public service model designed to strengthen community partnerships by connecting city services to the neighborhoods. The research setting was the Neighbourhood Integrated Service Teams (NIST) program in Vancouver, B.C., Canada. A literature review related information dimensions to the municipal structure, including social network theory, social network analysis, social capital, transactive memory theory, public goods theory, and the information environment of the public administration setting. The research method involved multiple instruments and included surveys of two bounded populations. First, the membership of the NIST program received a survey asking for identification of up to 20 people they contact for NIST-related work. Second, a network component of the NIST program, 23 community centre coordinators in the Parks and Recreation Department, completed a survey designed to identify their information exchanges relating to regular work responsibilities and the infusion of NIST issues. Additionally, 25 semi-structured interviews with the coordinators and other program members, collection of organization documents, field observation, and feedback sessions provided valuable insight into the complexity of the model. This research contributes to the application of social network theory and analysis in information environments and provides insight for public administrators into the operation of the model and reasons for the program's network effectiveness.

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

Description: 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 media as well as the actual budget and employee loss impact of the consolidation in order to better understand the impacts on knowledge workers and knowledge documents as a result of major organizational restructuring. The findings have both theoretical and practical implications for information science, knowledge management and project management.

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

Description: 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 of functional foods, nordihydroguaiaretic acid and breast cancer were searched with designated combinatorial keywords. The documents retrieved were subjected to author cocitation analysis to demonstrate disjointness or connectivity of the two complementary literatures. The results demonstrated a possible preventative relationship between breast cancer in women and nordihydroguaiaretic acid, a phytochemical antioxidant and potential functional food. The results of this study are consistent with D.R. Swanson's pioneering work in knowledge synthesis. Swanson's methods can be used to identify non-interactive, disjoint literatures. Continuing support for his techniques has been demonstrated.
