The Relationships Among a Reading Guidance Program and the Reading Attitudes, Reading Achievement, and Reading Behavior of Fifth Grade Children in a North Louisiana School

The Relationships Among a Reading Guidance Program and the Reading Attitudes, Reading Achievement, and Reading Behavior of Fifth Grade Children in a North Louisiana School

Date: August 1986
Creator: Mosley, Mattie Jacks
Description: The purpose of this study was to determine whether or not the introduction of a regular librarian-centered reading guidance program as an integral part of the entire school program would improve the reading attitudes and habits of elementary school students and increase the reading achievement scores on a standardized test of elementary school students. In addition, the reading attitudes of students were compared with reading achievement scores to assess any relationship between the two.

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 ...

Respect for human rights and the rise of democratic policing in Turkey: Adoption and diffusion of the European Union acquis in the Turkish National Police.

Respect for human rights and the rise of democratic policing in Turkey: Adoption and diffusion of the European Union acquis in the Turkish National Police.

Date: August 2007
Creator: Lofca, Izzet
Description: This study is an exploration of the European Union acquis adoption in the Turkish National Police. The research employed the Diffusion of Innovations, Democratic Policing, and historical background check theoretical frameworks to study the decision-making of the TNP regarding reforms after 2003 as a qualitative case study which triangulated the methodology with less-dominant survey and several other analyzing methods. The data were collected from several sources including semi-structured interviews, archival records, documentary evidences and the European Commission Regular Reports on Turkey. The research interest was about the decision mechanisms of the TNP towards reforms and the rise of democratic policing in Turkey. During the study, internationally recognized human rights standards were given attention. As the data suggested, the police forces are shaped according to their ruling governments and societies. It is impossible to find a totally democratic police in a violent society and a totally violent police in a democratic society. The study findings suggested that reforming police agencies should not be a significant problem for determined governments. Human rights violations should not be directly related with the police in any country. The data suggested that democratic policing applications find common application when the democracy gets powerful and police brutality ...

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

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

Date: December 2007
Creator: Wachanga, David Ndirangu
Description: 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 ...

The Second Vatican Council and American Catholic theological research: A bibliometric analysis of Theological Studies: 1940-1995

The Second Vatican Council and American Catholic theological research: A bibliometric analysis of Theological Studies: 1940-1995

Date: August 2000
Creator: Phelps, Helen Stegall
Description: A descriptive analysis was given of the characteristics of the authors and citations of the articles in the journal Theological Studies from 1940-1995. Data was gathered on the institutional affiliation, geographic location, occupation, and gender and personal characteristics of the author. The citation characteristics were examined for the cited authors, date and age of the citations, format, language, place of publication, and journal titles. These characteristics were compared to the time-period before and after the Second Vatican Council in order to detect any changes that might have occurred in the characteristics after certain recommendations by the council were made to theologians. Subject dispersion of the literature was also analyzed. Lotka's Law of author productivity and Bradford's Law of title dispersion were also performed for this literature. The profile of the characteristics of the authors showed that the articles published by women and laypersons has increased since the recommendations of the council. The data had a good fit to Lotka's Law for the pre-Vatican II time period but not for the period after Vatican II. The data was a good fit to Bradford's Law for the predicted number of journals in the nucleus and Zone 2, but the observed number of ...

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.

Smoothing the information seeking path: Removing representational obstacles in the middle-school digital library.

Date: May 2002
Creator: Abbas, June M.
Description: Middle school student's interaction within a digital library is explored. Issues of interface features used, obstacles encountered, search strategies and search techniques used, and representation obstacles are examined. A mechanism for evaluating user's descriptors is tested and effects of augmenting the system's resource descriptions with these descriptors on retrieval is explored. Transaction log data analysis (TLA) was used, with external corroborating achievement data provided by teachers. Analysis was conducted using quantitative and qualitative methods. Coding schemes for the failure analysis, search strategies and techniques analysis, as well as extent of match analysis between terms in student's questions and their search terms, and extent of match analysis between search terms and controlled vocabulary were developed. There are five chapters with twelve supporting appendixes. Chapter One presents an introduction to the problem and reviews the pilot study. Chapter Two presents the literature review and theoretical basis for the study. Chapter Three describes the research questions, hypotheses and methods. Chapter Four presents findings. Chapter Five presents a summary of the findings and their support of the hypotheses. Unanticipated findings, limitations, speculations, and areas of further research are indicated. Findings indicate that middle school users interact with the system in various sequences of patterns. ...

Solutions for Dynamic Channel Assignment and Synchronization Problem for Distributed Wireless Multimedia System

Solutions for Dynamic Channel Assignment and Synchronization Problem for Distributed Wireless Multimedia System

Date: August 2002
Creator: Hong, SungBum
Description: The recent advances in mobile computing and distributed multimedia systems allow mobile hosts (clients) to access wireless multimedia Data at anywhere and at anytime. In accessing multimedia information on the distributed multimedia servers from wireless personal communication service systems, a channel assignment problem and synchronization problems should be solved efficiently. Recent demand for mobile telephone service have been growing rapidly while the electro-magnetic spectrum of frequencies allocated for this purpose remain limited. Any solution to the channel assignment problem is subject to this limitation, as well as the interference constraint between adjacent channels in the spectrum. Channel allocation schemes provide a flexible and efficient access to bandwidth in wireless and mobile communication systems. In this dissertation, both an efficient distributed algorithm for dynamic channel allocation based upon mutual exclusion model, and an efficient distributed synchronization algorithm using Quasi-sink for wireless and mobile multimedia systems to ensure and facilitate mobile client access to multimedia objects are proposed. Algorithm's performance with several channel systems using different types of call arrival patterns is determined analytically. A set of simulation experiments to evaluate the performance of our scheme using message complexity and buffer usage at each frame arrival time.

A Study of Graphically Chosen Features for Representation of TREC Topic-Document Sets

A Study of Graphically Chosen Features for Representation of TREC Topic-Document Sets

Access: Use of this item is restricted to the UNT Community.
Date: May 2000
Creator: Oyarce, Guillermo Alfredo
Description: Document representation is important for computer-based text processing. Good document representations must include at least the most salient concepts of the document. Documents exist in a multidimensional space that difficult the identification of what concepts to include. A current problem is to measure the effectiveness of the different strategies that have been proposed to accomplish this task. As a contribution towards this goal, this dissertation studied the visual inter-document relationship in a dimensionally reduced space. The same treatment was done on full text and on three document representations. Two of the representations were based on the assumption that the salient features in a document set follow the chi-distribution in the whole document set. The third document representation identified features through a novel method. A Coefficient of Variability was calculated by normalizing the Cartesian distance of the discriminating value in the relevant and the non-relevant document subsets. Also, the local dictionary method was used. Cosine similarity values measured the inter-document distance in the information space and formed a matrix to serve as input to the Multi-Dimensional Scale (MDS) procedure. A Precision-Recall procedure was averaged across all treatments to statistically compare them. Treatments were not found to be statistically the same 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 ...
