Masking Meaning
Chapter I describes the purpose of the project, which was to develop a body of work that exhibits my current thought process. The questions presented to myself consisted of the following: 1. How effective was the expression of my ideas socially and politically after the change to the work? 2. Was the minimal approach a tool that contributes or detracts from this effectiveness? 3. Did an increase in scale successfully act as an element of confrontation? Chapter II describes the inspiration behind the making of my work it also discusses problems encountered with an understanding of the viewer concerning imagery. Chapter III summarizes the methodology behind the execution of the new body of work. It also discusses how simplification of imagery works as a solution to my problems.

Assessing the Adlerian Personality Priorities: A Formal Instrument for Therapeutic Practice
The purpose of this study was to develop an effective formal instrument to assess the Adlerian personality priorities. The development of the Allen Assessment for Adlerian Personality Priorities, AAAPP, seeks to provide a strong comparability to assessing the Adlerian construct of personality priorities as the counselor interview. One hundred and seven participants were given the 1st administration of the AAAPP, Social Interest Scale and a demographic survey. Sixty-four participants completed a 2nd administration of the AAAPP two weeks later. Twenty participants experienced a counseling interview following the 2nd administration. The methods used to evaluate the validity and effectiveness of the AAAPP included: face validity, predictive validity, construct validity, test-retest reliability, multiple regression, Guttman split-half reliability and the Spearman Brown reliability.

Critical Theory and Preservice Art Education: One Art Teacher Educator's Journey of Equipping Art Teachers for Inclusion.
This qualitative action research study examines how critical theory defined and guided my practice as an art teacher educator while I provided inclusion training for seven preservice art teachers during their student teaching. Sources of data included a personal journal, the inclusion curriculum I created for the preservice teachers and questionnaires and interviews. Primary findings indicated that critical theory had a substantive impact on the evolving development of my teaching philosophy, in particular my attention to issues of power redistribution in the classroom and my developing notion of teaching as form of artistry. The findings of this study also indicate that the primary impact of critical theory upon the preservice teachers was the articulation of their personal narratives and its relation to the development of their teaching identities. Further, mentoring these preservice art teachers in critical theory increased their competence in solving educational dilemmas. A primary finding of this study was how significant of a role the supervising or mentor teacher plays in developing preservice teachers' identity. As this is acknowledged, valued and utilized, more collaborative relationships among these stakeholders in the education of the preservice art teacher can be forged. The study provides implications for art teacher educators as …

Perceived attributes of diffusion of innovation theory as predictors of Internet adoption among faculty members of Imam Mohammed Bin Saud University.
The Internet is the most common communication and research tool worldwide. Perusal of the World Wide Web quickly reveals the variety of information available. Internet adoption can be considered the late 20th century's most important event. In academic environments today, Internet use among faculty members has been widely expanded, with professors now integrating Internet technology into classroom activities. Imam Muhammad Bin Saud Islamic University (IMSU) is a pioneering public university in Saudi Arabia. Until recently, some faculty members at IMSU were unable to access the Internet through the university. It is important to study the effects of this delay on faculty members regarding research and academic activities. This study identified the statistically significant differences in demographic characteristics of Internet adopters and non-adopters among faculty members at IMSU, examined whether faculty members' perceptions of the Internet affected adoption, determined if the university administration's decisions impacted faulty members' decisions to adopt the Internet, identified factors motivating faculty members to adopt the Internet, identified obstacles influencing faculty members' decisions to use the Internet, and determined whether innovation characteristics as perceived by faculty members predicted Internet adoption. Using Rogers' diffusion of innovation theory, the influence of eight attributes were examined regarding Internet adoption among …

The Adoption and Use of Electronic Information Resources by a Non-Traditional User Group: Automotive Service Technicians.
The growing complexity of machines has led to a concomitant increase in the amount and complexity of the information needed by those charged with servicing them. This, in turn, has led to a need for more robust methods for storing and distributing information and for a workforce more sophisticated in its use of information resources. As a result, the service trades have "professionalized," adopting more rigorous academic standards and developing ongoing certification programs. The current paper deals with the acceptance of advanced electronic information technology by skilled service personnel, specifically, automotive service technicians. The theoretical basis of the study is Davis' technology acceptance model. The purpose of the study is to determine the effects of three external factors on the operation of the model: age, work experience, and education/certification level. The research design is in two parts, beginning with an onsite observation and interviews to establish the environment. During the second part of the research process a survey was administered to a sample of automotive service technicians. Results indicated significant inverse relationships between age and acceptance and between experience and acceptance. A significant positive relationship was shown between education, particularly certification, and acceptance.

Attitudes toward Research and Teaching: Differences Between Faculty and Administrators at Three Saudi Arabian Universities
Access:
Use of this item is restricted to the UNT Community
This study is an investigation of the perceived attitudinal differences between administrators and faculty toward research and teaching at three Saudi Arabian universities, King Saud University (KSU), King Fahd University of Petroleum and Minerals (KFUPM), and the Islamic University (IU). The researcher also investigated the effect of several variables, such as rank, university, and academic field on administrators and faculty members' attitudes toward teaching and research. Little Attention has been given to studies that examine the differences between faculty and administrators with regard to their attitudes toward the priorities of teaching and research in Saudi Arabian institutions. Also, little research has been conducted regarding the effects of rank and academic field on faculty attitudes in Saudi Arabian institutions. The author used a mail survey and collected 518 useable responses from a total of 710 questionnaires distributed. Factor analysis, MANCOVA, MANOVA, and ANOVA were the statistical methods employed in data analysis. Five attitudes were identified as a result of factor analysis: (a) attitudes toward teaching; (b) attitudes toward research; (c) mission; (d) promotion; and (e) interest. Results indicated that there was a significant difference between faculty and administrators regarding teaching and resea4rch. Administrators showed stronger attitudes toward teaching than faculty at …

Study of Substituted Benzenesulfonate-Containing Layered Double Hydroxides and Investigation of the Hexamethylenetetramine Route of LDH Synthesis
Benzenesulfonates, para-substituted with amine, chloride and methyl groups were successfully incorporated into layered double hydroxides of two different compositions, 2:1 Mg-Al LDH and 2:1 Zn-Al LDH. These parent materials were also doped with small amounts of nickel and the differences in the two systems were studied. The hexamethylenetetramine route of layered double hydroxide synthesis was investigated to verify if the mechanism is indeed homogeneous. This included attempting preparation of 2:1 Mg-Al LDH, 2:1 Zn-Al LDH and 2:1 Zn-Cr LDH with two different concentrations of hexamethylenetetramine. The analytical data of the products suggest that the homogeneous precipitation may not be the true mechanism of reaction involved in LDH synthesis by this method.

An Integrated Architecture for Ad Hoc Grids
Extensive research has been conducted by the grid community to enable large-scale collaborations in pre-configured environments. grid collaborations can vary in scale and motivation resulting in a coarse classification of grids: national grid, project grid, enterprise grid, and volunteer grid. Despite the differences in scope and scale, all the traditional grids in practice share some common assumptions. They support mutually collaborative communities, adopt a centralized control for membership, and assume a well-defined non-changing collaboration. To support grid applications that do not confirm to these assumptions, we propose the concept of ad hoc grids. In the context of this research, we propose a novel architecture for ad hoc grids that integrates a suite of component frameworks. Specifically, our architecture combines the community management framework, security framework, abstraction framework, quality of service framework, and reputation framework. The overarching objective of our integrated architecture is to support a variety of grid applications in a self-controlled fashion with the help of a self-organizing ad hoc community. We introduce mechanisms in our architecture that successfully isolates malicious elements from the community, inherently improving the quality of grid services and extracting deterministic quality assurances from the underlying infrastructure. We also emphasize on the technology-independence of our …

Resource Efficient and Scalable Routing using Intelligent Mobile Agents
Many of the contemporary routing algorithms use simple mechanisms such as flooding or broadcasting to disseminate the routing information available to them. Such routing algorithms cause significant network resource overhead due to the large number of messages generated at each host/router throughout the route update process. Many of these messages are wasteful since they do not contribute to the route discovery process. Reducing the resource overhead may allow for several algorithms to be deployed in a wide range of networks (wireless and ad-hoc) which require a simple routing protocol due to limited availability of resources (memory and bandwidth). Motivated by the need to reduce the resource overhead associated with routing algorithms a new implementation of distance vector routing algorithm using an agent-based paradigm known as Agent-based Distance Vector Routing (ADVR) has been proposed. In ADVR, the ability of route discovery and message passing shifts from the nodes to individual agents that traverse the network, co-ordinate with each other and successively update the routing tables of the nodes they visit.

The Impact of Visceral Influences on Consumers' Evaluation of Weight Loss Advertising
The weight loss industry has come under fire from the Federal Trade Commission (FTC) in recent years due to consumer claims that many firms, marketing weight loss products, are using advertisements in an attempt to deceive consumers. Illegitimate weight loss claims have created so much concern that a White Paper call-to-action to investigate misleading weight loss advertisements has been filed. Despite recent interest, little attention has been garnered concerning the understanding of why consumers respond to potentially misleading weight loss claims. Intuitively, an understanding of why consumers fall prey to weight loss claims may aid academics, practitioners, and policy makers as they make important decisions relative to the weight loss industry and its practices. This study fills that void by applying a theory of visceral influences (TVI) to the context of weight loss advertising. Loewenstein's TVI was developed to aid in explaining why consumers make decisions contrary to their long-term self-interest. Visceral influences are drive states that have a direct hedonic impact, have an effect on the relative desirability of various goods and activities, and consequently, have a strong influence over the decisions consumers make. Common visceral cues (cues associated with any reward linked to a visceral factor) include proximity …

An examination of the effects of accuracy+rate versus accuracy+observing response training methods on matching-to-sample performance.
The relative efficacy of training procedures emphasizing accuracy versus those which add a rate criterion is a topic of debate. The desired learning outcome is fluent responding, assessed by measures of retention, endurance, stability, and application. The current study examined the effects of these two procedures on fluency outcomes using a matching-to-sample paradigm to train participants to match English to Japanese characters. An explicit FR-3 observing response was added to an accuracy-only condition to assess the extent to which it may facilitate learning. Total time spent responding in practice drills in accuracy-only conditions was yoked to total time spent in drills achieving rate aims in accuracy+rate (AR) conditions. One participant clearly demonstrated superior fluency outcomes after AR training while another displayed superior endurance and stability outcomes after such training. The remaining two participants did not demonstrate significantly different fluency outcomes across conditions.

The Effects of Extinction on Human Performance Following Exposure to Fixed Ratio Schedules of Reinforcement
This experiment examined the effects of extinction on rate of responding and several topographical and temporal measures in adult humans. Three college students were trained to type the sequence 1•5•3 on a numeric keypad on a computer. The subjects were exposed to different fixed-ratio schedules of reinforcement (FR1, FR 5, and FR10 respectively) and extinction. Subjects displayed typical schedule performances during the maintenance phase of the experiment. During extinction the performances were disrupted, they showed a "break and run" pattern and a general decrease in responding. Also, new topographical and temporal patterns emerged. These data are consistent with those reported for non-human species and special human populations.

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

Virtual Teams and Technology: The Relationship between Training and Team Effectiveness
The impact of training on virtual team effectiveness was assessed in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. A 12-page survey was developed exploring all aspects of virtual teams. 180 surveys were distributed, 52 were returned representing 43 companies. Training led to higher effectiveness in planning tasks and setting goals, solving problems and making decisions, and conflict resolution, but not in communication and responding to customer requirements. Training may not solve all the problems that virtual teams will encounter; however, training will make the challenges easier to handle.

Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions.
The purpose of the study was to investigate the perceptions of job satisfaction as defined by management and nonmanagement employees and to compare both parties' perceptions of organizational benefits to a list prepared by the organization's benefit personnel. Turnover is costly to the organization, both in money and in the impact it has on those individuals remaining with the organization. Every effort should be undertaken to reduce the amount of turnover within the organization. A contributing factor leading to turnover may be a gap between what the employees believe is important to them and what management believes is important to the employees. The boundaries of the gap need to be identified before any effort can be made to reduce or bridge the gap. Once the boundaries are identified, policies can be analyzed and the possibility of reducing the gap investigated. Management as a whole must be aware of the needs and wants of their employees before any attempt to develop a retention strategy is undertaken. This knowledge can be acquired only through two-way communication with the employee. The communication process includes the simple process of asking employees for this information and then listening to how they respond. This study suggests …

Content-Based Image Retrieval by Integration of Metadata Encoded Multimedia Features in Constructing a Video Summarizer Application.
Content-based image retrieval (CBIR) is the retrieval of images from a collection by means of internal feature measures of the information content of the images. In CBIR systems, text media is usually used only to retrieve exemplar images for further searching by image feature content. This research work describes a new method for integrating multimedia text and image content features to increase the retrieval performance of the system. I am exploring the content-based features of an image extracted from a video to build a storyboard for search retrieval of images. Metadata encoded multimedia features include extracting primitive features like color, shape and text from an image. Histograms are built for all the features extracted and stored in a database. Images are searched based on comparing these histogram values of the extracted image with the stored values. These histogram values are used for extraction of keyframes from a collection of images parsed from a video file. Individual shots of images are extracted from a video clip and run through processes that extract the features and build the histogram values. A keyframe extraction algorithm is run to get the keyframes from the collection of images to build a storyboard of images. In …

The Influence of Fredrik Melius Christiansen on Six Minnesota Conductor-Composers
F. Melius Christiansen was very influential in the a cappella choral tradition. He started his career in Norway and brought his expertise to the American Midwest. Christiansen established a name for himself while working at St. Olaf Lutheran College as the head of the music department. It was the blended choral sound and precision he was able to achieve and display with his new choir in 1912 that caught everyone's ear. He continued to succeed with national and international tours, allowing him to spread his new "St. Olaf" choral sound through his music, compositions, and conducting school. This study explores the influence of F. Melius Christiansen (1871-1955) and the Minnesota choral tradition on six subsequent conductor-composers' compositions and conducting styles, including: Olaf Christiansen (1901-1984), Paul J. Christiansen (1914-1997), Kenneth Jennings (b. 1925), Robert Scholz (b. 1940), René Clausen (b. 1953), and Kenneth Hodgson (b. 1939) using Schenkerian analysis.

The Effects of Biofeedback and Verbal Feedback on the Training and Maintenance of Diaphragmatic Breathing
The purpose of this study was to evaluate the effects of a computer program on the training and maintenance of diaphragmatic breathing. The biofeedback portion was visual computer training and the results were displayed concurrently with participants' breathing responses to monitor display. The verbal feedback portion was praise that was given and recorded when participants responded with predominantly diaphragmatic breathing at the scheduled moment and response instruction that was given when participants responded with predominantly thoracic breathing. The results of this study indicate the computer program's effectiveness needs to be increased by supplementation with verbal feedback.
