Relevance Thresholds: A Conjunctive/Disjunctive Model of End-User Cognition as an Evaluative Process

Relevance Thresholds: A Conjunctive/Disjunctive Model of End-User Cognition as an Evaluative Process

Date: December 2000
Creator: Greisdorf, Howard F.
Description: This investigation identifies end-user cognitive heuristics that facilitate judgment and evaluation during information retrieval (IR) system interactions. The study extends previous research surrounding relevance as a key construct for representing the value end-users ascribe to items retrieved from IR systems and the perceived effectiveness of such systems. The Lens Model of user cognition serves as the foundation for design and interpretation of the study; earlier research in problem solving, decision making, and attitude formation also contribute to the model and analysis. A self reporting instrument collected evaluative responses from 32 end-users related to 1432 retrieved items in relation to five characteristics of each item: topical, pertinence, utility, systematic, and motivational levels of relevance. The nominal nature of the data collected led to non-parametric statistical analyses that indicated that end-user evaluation of retrieved items to resolve an information problem at hand is most likely a multi-stage process. That process appears to be a cognitive progression from topic to meaning (pertinence) to functionality (use). Each step in end-user evaluative processing engages a cognitive hierarchy of heuristics that includes consideration (of appropriate cues), differentiation (the positive or negative aspects of those cues considered), and aggregation (the combination of differentiated cue aspects needed to ...

Information Needs of Art Museum Visitors: Real and Virtual

Information Needs of Art Museum Visitors: Real and Virtual

Date: December 2004
Creator: Kravchyna, Victoria
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 ...

Factors Influencing How Students Value Asynchronous Web Based Courses

Factors Influencing How Students Value Asynchronous Web Based Courses

Date: December 1999
Creator: Pérez Cereijo, Maria Victoria
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 ...

Negotiation, communication, and decision strategies used by hostage/crisis negotiators.

Negotiation, communication, and decision strategies used by hostage/crisis negotiators.

Date: May 2008
Creator: Hancerli, Suleyman
Description: By conducting this theory-based empirical study, gathering data from working negotiators in the US and Canada, I have determined what primary dynamic activities, communication skills, and negotiation tools are used by hostage/crisis negotiators. Negotiators implement their negotiation and decision strategies differently depending on whether the situations they deal with are instrumental or expressive. I have determined which elements of negotiations and factors affecting negotiations differ while handling instrumental and expressive hostage situations. I found that the collected data did not reveal any significant relationship between handling instrumental/expressive hostage situations differently and belief in the elements of Brenda Dervin's and Shannon-Weaver's theories. I have also determined that the belief in the elements of the Dervin's and Shannon-Weaver's theories is workable and practical for negotiators to use. Based on the above findings, the model suggested by this research adds the elements and directives of Dervin's and Shannon-Weaver's models to the common approach used by the negotiators. This revised model suggests that the negotiators pay attention to the dynamics of the interactions presented between the two parties: the negotiators themselves and hostage takers. The revised model also recommends that the negotiators focus on not only the hostage takers behavioral characteristics, psychological conditions, and ...

A study of on-line use and perceived effectiveness of compliance-gaining in health-related banner advertisements for senior citizens.

A study of on-line use and perceived effectiveness of compliance-gaining in health-related banner advertisements for senior citizens.

Date: December 2002
Creator: Toon, Michelle Anne
Description: This research investigated banner ads on the World Wide Web, specifically the types of messages used in those ads and the effectiveness of the ads as seen by their intended audience. The focus was on health-related banner advertisements targeting senior citizens. The study first sought to determine the frequency of appearance of those ads when classified into categories of compliance-gaining tactics provided by research scholars. Second, the study explored the relative perceived effectiveness among those categories. Two graduate students from a Central Texas university sorted text messages into predetermined compliance-gaining categories. Chi square tests looked for significant differences in the frequencies of banner ads in each category. Forty-five senior citizens from the Central Texas area completed surveys regarding the perceived effectiveness of a randomly ordered, randomly selected set of categorized banner ads. A repeated measures test attempted to determine whether some compliance-gaining strategies used in health-related banner ads were perceived as more effective than others. The hypothesis stated that there would be differences in frequencies of compliance-gaining strategies used among the compliance-gaining categories in health-related banner ads for senior citizens. The hypothesis was supported. The research question asked if some categories of compliance-gaining strategies used in health-related banner ads were ...

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

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

Date: August 2001
Creator: Kearns, Jodi
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 hypothesized, mechanically calculated entropy measure (CEM) was found to be sufficiently similar to perceived entropy measure (PEM) made by children so that they can be used as useful and predictive elements of representations of children’s videos. The relationships between the CEM and the PEM show that CEM could stand for PEM in order to enrich representations for video documents for this age group. Speculations on transferring the CEM to PEM calibration to different age groups and different document types are made, as well as further implications for the field of information science.

MEDLINE Metric: A method to assess medical students' MEDLINE search effectiveness

MEDLINE Metric: A method to assess medical students' MEDLINE search effectiveness

Date: May 2000
Creator: Hannigan, Gale G.
Description: Medical educators advocate the need for medical students to acquire information management skills, including the ability to search the MEDLINE database. There has been no published validated method available to use for assessing medical students' MEDLINE information retrieval skills. This research proposes and evaluates a method, designed as the MEDLINE Metric, for assessing medical students' search skills. MEDLINE Metric consists of: (a) the development, by experts, of realistic clinical scenarios that include highly constructed search questions designed to test defined search skills; (b) timed tasks (searches) completed by subjects; (c) the evaluation of search results; and (d) instructive feedback. A goal is to offer medical educators a valid, reliable, and feasible way to judge mastery of information searching skill by measuring results (search retrieval) rather than process (search behavior) or cognition (knowledge about searching). Following a documented procedure for test development, search specialists and medical content experts formulated six clinical search scenarios and questions. One hundred and forty-five subjects completed the six-item test under timed conditions. Subjects represented a wide range of MEDLINE search expertise. One hundred twenty complete cases were used, representing 53 second-year medical students (44%), 47 fourth-year medical students (39%), and 20 medical librarians (17%). Data related ...
