The Emergence of Organization Through Communication
Taylor, Cooren, Giroux, and Robichaud (1996) theorize that an organization is created entirely through the interpretations of its members and it evolves as those conversations change. Demonstrating the Taylor et al. theory, the current study focuses on the outcomes of management vision and strategic planning sessions in a division of a large Southwestern University. It explores the ways organization emerges through the discourse of the managers, how text is amplified to support the organization as a whole, the ways organization continues to emerge in communication, and in what ways the emergent view of organization exists throughout the division. The results of the study support the Taylor et al. theory. Management participants created an expanded view of the organization through discourse and then linked it to the university as a whole. Evidence was found supporting continued reformulation but it was limited to the management participants and did not include hourly employees.

Computer Supported Collaboration: Is the Transfer of Cognitive Structures Mediated by Mode of Communication?
The objective of this study was to observe evidence of structural transfer among subjects in a group problem-solving activity and determine whether mode of collaborative technology or use of a priming agent affected the nature of transferred structures. Evidence for structural transfer is found in three theoretical perspectives: organizational ditransitive (linguistic) verb structures, adaptive structuration theory, and mental model transfer theory. Dependent variables included various grammatical structures and coefficients derived from pretest and posttest scores on David Kolb's Learning Styles Inventory, modified for the experiment. The combination of changes in grammatical frequencies and learning style may suggest that one or more media or the priming agent may affect structural transfer. Results indicate that groups using the GroupSystems collaborative technology produced less overall linguistic content than did subjects using a generic chat system, but employed more complex language as indicated by frequency of the organizational ditransitive verb structure. Also, subjects supplied with an organization chart (priming agent) during the group problem-solving session experienced greater change on the learning styles inventory than did those participating in the session without the chart. These findings suggest that mode of communication and use of priming agents may contribute positively or negatively to the transfer of …

A Comparison of Communication Motives of On-Site and Off-Site Students in Videoconference-Based Courses
The objective of this investigation is to determine whether student site location in an instructional videoconference is related to students' motives for communicating with their instructor. The study is based, in part, on the work of Martin et al. who identify five separate student-teacher communication motives. These motives, or dimensions, are termed relational, functional, excuse, participation, and sycophancy, and are measured by a 30-item questionnaire. Several communication-related theories were used to predict differences between on-site and off-site students, Media richness theory was used, foundationally, to explain differences between mediated and face-to-face communication and other theories such as uncertainty reduction theory were used in conjunction with media richness theory to predict specific differences.Two hundred eighty-one completed questionnaires were obtained from Education and Library and Information Science students in 17 separate course-sections employing interactive video at the University of North Texas during the Spring and Summer semesters of the 2001/2002 school year. This study concludes that off-site students in an instructional videoconference are more likely than their on-site peers to report being motivated to communicate with their instructor for participation reasons. If off-site students are more motivated than on-site students to communicate as a means to participate, then it may be important …

Low Dose Risk, Decisions, & Risk Communication
The objective of this project is to conduct basic research on how people receive, evaluate, and form positions on scientific information and its relationship to low-dose radiation exposure. There are three major areas of study in our research program. First is the development of theories, frameworks and concepts essential to guiding data collection and analysis. The second area is a program of experimental studies on risk perception, evaluation of science information, and the structure of individual positions regarding low-dose exposures. Third is the community-level studies to examine and record how the social conditions, under which science communications take place, influence the development of attitudes and opinions about: low-dose exposures, the available management options, control of radiation risks, and preferences for program and policy goals.

More than just wires : applying complexity theory to communications network assurance.
Complexity Theory is the study of order within otherwise chaotic systems (Holland, 1999). Complexity Theory often focuses on Complex Adaptive Systems (CAS). A CAS is a system of components that interact and reproduce while adapting to their environment. A CAS consists of large numbers of components that are diverse in both form and capability. A CAS exhibits unstable coherence in spite of constant disruptions and a lack of central planning. Large-scale, interconnected infrastructures such as communication networks are CAS. These infrastructures are vastly more dynamic than their predecessors. Such infrastructures consist of a large number of components and participants that are diverse in both form and capability. Furthermore, these infrastructures exhibit unstable coherence in spite of constant disruptions and a lack of central planning. Viewing large-scale, interconnected infrastructures with complex physical architectures, such as communication networks, as CAS can provide many new insights (Bower and Bunn, 2000; North, 2000a, 2000b, and 2001). The CAS approach emphasizes the specific evolution of integrated infrastructures and their participants' behavior, not just simple trends or end states. The adaptation of the infrastructure participants to changing conditions is paramount. Also, the effects of random events and uncertainty are explicitly considered. One powerful computational approach to …

The Theory of Random Laser Systems
Studies of random laser systems are a new direction with promising potential applications and theoretical interest. The research is based on the theories of localization and laser physics. So far, the research shows that there are random lasing modes inside the systems which is quite different from the common laser systems. From the properties of the random lasing modes, they can understand the phenomena observed in the experiments, such as multi-peak and anisotropic spectrum, lasing mode number saturation, mode competition and dynamic processes, etc. To summarize, this dissertation has contributed the following in the study of random laser systems: (1) by comparing the Lamb theory with the Letokhov theory, the general formulas of the threshold length or gain of random laser systems were obtained; (2) they pointed out the vital weakness of previous time-independent methods in random laser research; (3) a new model which includes the FDTD method and the semi-classical laser theory. The solutions of this model provided an explanation of the experimental results of multi-peak and anisotropic emission spectra, predicted the saturation of lasing modes number and the length of localized lasing modes; (4) theoretical (Lamb theory) and numerical (FDTD and transfer-matrix calculation) studies of the origin of …

The Information Environment of Academic Library Directors: Use of Information Resources and Communication Technologies
Access:
Use of this item is restricted to the UNT Community
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; …

Combination of Evidence in Dempster-Shafer Theory
Dempster-Shafer theory offers an alternative to traditional probabilistic theory for the mathematical representation of uncertainty. The significant innovation of this framework is that it allows for the allocation of a probability mass to sets or intervals. Dempster-Shafer theory does not require an assumption regarding the probability of the individual constituents of the set or interval. This is a potentially valuable tool for the evaluation of risk and reliability in engineering applications when it is not possible to obtain a precise measurement from experiments, or when knowledge is obtained from expert elicitation. An important aspect of this theory is the combination of evidence obtained from multiple sources and the modeling of conflict between them. This report surveys a number of possible combination rules for Dempster-Shafer structures and provides examples of the implementation of these rules for discrete and interval-valued data.

Coherent synchrotron radiation: Theory and experiments
Our understanding of the generation of coherent synchrotron radiation in magnetic bending systems and its impact on beam dynamics has grown considerably over the past few years. The search for understanding has brought a number of surprises, all related to the complexity of the fully self-consistent problem. Herein I survey the associated phenomenology, theory, and experiments while emphasizing important subtleties that have recently been uncovered. I conclude by speculating on courses of future investigations that may prove fruitful.

Graphical Model Theory for Wireless Sensor Networks
Information processing in sensor networks, with many small processors, demands a theory of computation that allows the minimization of processing effort, and the distribution of this effort throughout the network. Graphical model theory provides a probabilistic theory of computation that explicitly addresses complexity and decentralization for optimizing network computation. The junction tree algorithm, for decentralized inference on graphical probability models, can be instantiated in a variety of applications useful for wireless sensor networks, including: sensor validation and fusion; data compression and channel coding; expert systems, with decentralized data structures, and efficient local queries; pattern classification, and machine learning. Graphical models for these applications are sketched, and a model of dynamic sensor validation and fusion is presented in more depth, to illustrate the junction tree algorithm.

A Comparison of the Cognitive Style Similarity and Communication Style Adjustment Index Methods to Study Counseling Supervision Performance
This study was designed to examine two questions. First, does increasing Myers-Briggs Type similarity correlate with improved performance by counselor supervisor/supervisee dyads? Second, is the Communication Style Adjustment Index superior to the cognitive style scale matching procedure as a method of quantifying MBTI similarity in dyads? Sixty-eight supervisor/supervisee dyads were recruited from University of North Texas Counselor Education Master's level practicum classes. Supervisee class rankings and supervisor performance ratings were correlated with the dyads' MBTI similarity as measured by the Communication Style Adjustment Index and the cognitive style matching procedure. While none of the hypotheses were supported it was noted that there was interaction approaching significance between dyadic similarity using the Communication Style Adjustment Index and supervisor performance ratings.

Constitutive Theory for Velocity Dispersion in Rock with Dual Porosity
The high frequency behavior of the bulk modulus of fluid-saturated rock can be obtained from a double-porosity constitutive model, which is a direct conceptual extension of Biot's (1941) constitutive equations and which provides additional stiffening due to unrelaxed induced pore pressures in the soft porosity phase. Modeling the stiffening of the shear modulus at high frequency requires an effective medium average over the unequal induced pore pressures in cracks of different orientations. The implicit assumptions are that pore fluid equilibration does not occur between cracks of different orientations and between cracks and porous matrix. The correspondence between the constitutive equations of Berryman and Wang (1995) and Mavko and Jizba (1991) is explicitly noted.

Theory and Simulation of the Physics of Space Charge Dominated Beams
This report describes modeling of intense electron and ion beams in the space charge dominated regime. Space charge collective modes play an important role in the transport of intense beams over long distances. These modes were first observed in particle-in-cell simulations. The work presented here is closely tied to the University of Maryland Electron Ring (UMER) experiment and has application to accelerators for heavy ion beam fusion.

Levels of resourcefulness and motivation as they relate to sales force success: An examination of correlates using the hope theory.
This study sought to determine whether a relationship existed between individual salesperson's levels of goal-directed cognition and motivation and their professional success as determined by the percentage of sales goals achieved. Salespersons represented two companies with national sales forces: one from the financial services industry and one from the apparel manufacturing industry. Both groups of salespeople were responsible for complex selling tasks. The skill sets for these professionals included high levels of communication skills, extensive product knowledge, and competitive market knowledge. Survey research, both paper and pencil and online, was conducted using the Hope Scale developed by C. R. Snyder and associates (1991). Hope is defined as a two-dimensional construct of goal-directed thinking: resourcefulness, thoughtful planning to overcome obstacles to goals, and motivation, cognition to sustain momentum toward goal achievement. Theoretically, upon assessing salespersons' Hope scores, organizations would be better prepared to assist those with low Hope Scale Scores (HSS) in one of the two areas. Those with low resourcefulness scores could be trained in cognitive techniques to overcome obstacles to goal achievement. Those with low motivational scores would be identified for further analysis, from a developmental perspective, to better determine what personally initiates and sustains motivation to attain their …

Authenticated group Diffie-Hellman key exchange: theory and practice
Authenticated two-party Diffie-Hellman key exchange allows two principals A and B, communicating over a public network, and each holding a pair of matching public/private keys to agree on a session key. Protocols designed to deal with this problem ensure A (B resp.)that no other principals aside from B (A resp.) can learn any information about this value. These protocols additionally often ensure A and B that their respective partner has actually computed the shared secret value. A natural extension to the above cryptographic protocol problem is to consider a pool of principals agreeing on a session key. Over the years several papers have extended the two-party Diffie-Hellman key exchange to the multi-party setting but no formal treatments were carried out till recently. In light of recent developments in the formalization of the authenticated two-party Diffie-Hellman key exchange we have in this thesis laid out the authenticated group Diffie-Hellman key exchange on firmer foundations.
