Isolation And Identification Of Proteoglycans In Human Glenohumeral Joint Capsule., Susan Jeno

Theses and Dissertations

Characterization of the biochemical structure of cartilage and tendon has been a focus of research in recent decades, but little is known about joint capsules. Classified as dense irregular connective tissue, the extracellular matrix of joint capsules contains water, collagen, and non-collagenous macromolecules including proteoglycans (PGs), and glycoproteins, but specific biochemical composition of human glenohumeral joint capsule has not been elucidated. Structure and function are intimately related, therefore, understanding the structure of the capsule is essential to analysis of its function. The purpose of this research study was to isolate and characterize the PG content and relative proportion of each …

The Perspectives Of Care And Justice And Their Influence On Clinician Conceptualization Of Client Anger., Dona Corcoran Zanotti

Theses and Dissertations

Anger is a dominant, but under-researched, emotion in our society. Mental health providers devote a considerable portion of their time to helping clients deal with anger. However, neither they nor researchers are able to say what treatment is most efficacious or for whom. Gender, age, and culture are all involved in the experience and expression of anger and how anger manifests itself differently among individuals, and possibly in how anger is interpreted by mental health providers. One way to better understand client anger and clinician's conceptualization of that anger is through the examination of anger narratives. This study examined anger …

N-Acetyltransferase Genetic Polymorphisms And Breast Cancer Risk., Anne Carlson Deitz

Theses and Dissertations

Aromatic and heterocyclic amine carcinogens found in cigarette smoke and well done meat require host-mediated metabolic activation before initiating tumors in target organs. The N-acetyltransferase isozymes, NAT1 and NAT2, catalyze the activation (O-acetylation) of aromatic and heterocyclic amines and also the deactivation (N-acetylation) of aromatic amines. Both NAT1 and NAT2 are subject to genetic polymorphisms. Using molecular epidemiological studies, in vitro studies in human mammary tissues, and a genetically defined rapid and slow acetylator congenic hamster model, we tested our hypothesis that rapid NAT1 and/or NAT2 acetylators are at an increased risk of breast cancer, especially those women exposed to …

Grounded Theory On How Instructional Assessments Inform Policy On Undergraduate Learning And Skill Development., Deborah Marie Suzzane

Theses and Dissertations

The purpose was to produce a grounded theory on how instructional assessments inform policy with an explanation of what undergraduates learn and can do. By 1989, higher education in the United States received a mandate from the accrediting agencies to assess in undergraduate education. The Secretary of Education demanded the mandate and associated accreditation with federal funding decisions. For Objective 1, a purposeful selection of 22 reported experiences from doctorate granting or masters' 1 comprehensive institutions in the north and central states was useful for producing the grounded theory. For Objective 2, a purposeful selection of two Midwest documents was …

A Research Guide And Cross-Reference To The "Reports Of The Royal Commission On Historical Manuscripts"., Thomas Martin Mulhern

Theses and Dissertations

The Reports of the Royal Commission on Historical Manuscripts is a treasure trove of information that has been almost impossible to unlock since its initial publication. The indexing is rudimentary and there was no cross-reference between reports which makes researching time consuming and frustrating. The object of this project was to provide students, teachers, and researchers with a key to unlock the information in the collection. To do this each volume was examined for content and cross-referenced to other volumes with similar topics. This produced a central collection, Report #9, which encompassed the Elizabethan era, and twenty-two other collections cross-referenced …

Boundary Control For Automated Sweeping Of Finite Element Meshes, Robert A. Kerr

Theses and Dissertations

Finite element analysis depends greatly upon a high-quality mesh to be able to provide reasonably accurate answers to engineering problems. Models that need to be analyzed using finite element analysis are becoming increasingly more complex, and correspondingly harder to mesh with good quality. Skew is one quality metric which can cause problems with finite element analyses. This thesis explains how skew is calculated, discusses two common sources of skew: multiply-linked surfaces with interval constraints, and biased edge meshes. Two methods of lessening skew in surface meshes are then presented: the skew control algorithm, and the curve morphing algorithm. These algorithms …

Of interest was the time required to input and proofread text processing tasks as well as the number …

A Numerical Simulation Of A Carbon Black Suspension Cell Via A Time-Reversed, Double Layer Compute Algorithm, Gregg T. Anderson

Theses and Dissertations

A numerical simulation of a carbon black suspension cell is explored which models a laser-induced plasma within a liquid ethanol medium of approximately 1 mm thickness. The simulation model assumes a laser pulse with a pulse width of approximately 9 nsecs propagating in the left-to-right direction striking the front surface of the medium and focusing to a spot within the liquid volume. When the energy density within a given irradiated volume is sufficiently high, it ignites the carbon particles and generates a large number of free electrons, i.e., a plasma. The plasma couples with the in-coming laser energy on a …

Towards A Game Theory Model Of Information Warfare, David A. Burke

Theses and Dissertations

The repeated game of incomplete information model, a subclass of game theory models, was modified to include aspects of information warfare. The repeated game of incomplete information model was first developed to analyze nuclear weapons disarmament negotiations. The central role of information in this model suggested its applicability to IW, which focuses on the defense and acquisition of information. A randomized experimental design was utilized to determine how people behave in a laboratory IW setting and to test the IW game model's basic predictions. The impact of experience and learning on IW performance was also assessed during the experiment. IW …

Power, Performance, And Perception (P3): Integrating Usability Metrics And Technology Acceptance Determinants To Validate A New Model For Predicting System Usage, Alan P. Fiorello

Theses and Dissertations

Currently, there are two distinct approaches to assist information technology managers in the successful implementation of office automation software. The first approach resides within the field of usability engineering, while the second approach is derived from the discipline of management information systems (MIS). However, neither approach has successfully produced conclusive evidence that explains what characteristics facilitate system use as well as influence user acceptance of the system. This study reports on the validity of a new model, entitled the Power, Performance, Perception (P3) model, that links the constructs of usability engineering to user acceptance. Additionally, speech recognition software (SRS) was …

Evaporation Of Jet Fuels, Charles Eric Hack

Theses and Dissertations

Determining the fate and transport of JP-8 jet fuel is a complex and important problem. As part of the startup procedures for jet engines, fuel is passed through aircraft engines before combustion is initiated. Because of the extremely low temperatures at northern tier Air Force bases, the unburned fuel does not evaporate readily and may come into contact with ground crew. To determine the amount and duration of contaminant contact, the evaporation of the emitted fuel must be modeled. The amount and composition of the fuel upon reaching the ground crew may be determined by droplet evaporation models that have …

Finite element analysis was used to study the relationship between the stress state created by the plastic damage …

Impact Of Actual Facilitator Alignment, Co-Location, And Video Intervention On The Efficacy Of Distributed Group Support Systems, Brian J. Heberlie, Mary O. Tolbert

Theses and Dissertations

The growth of distributed group support systems (GSS) suggests that organizations will continue to bring dispersed groups of people together to make decisions over computer networks. In many instances those groups are temporarily assembled to address a task and then summarily disbanded never to work together again. In order for users to effectively use the GSS issues of trust and control need to be addressed within the GSS design. Users have perceptions about the fairness of structural and social determinants of the GSS design. These perceptions influence both the decision making process and process outcomes. This article shows the negative …

Information System Incidents: The Development Of A Damage Assessment Model, Mark D. Horony

Theses and Dissertations

Information system (IS) incidents are on the rise. With low manning and undertrained information security specialists it is difficult for organizations to stop IS incidents from occurring. Once an incident has occurred it is the IS manager's responsibility to ensure that a full and accurate damage assessment has been accomplished. However, most IS managers lack the necessary tools to assess the damage from an incident. This exploratory thesis developed an IS incident damage assessment model (DAM) that can be part of the IS manager's tool kit. During the development of the model, it became apparent that the model was supported …

Why Didn’T You Tell Me?: Toward Building A Model Of Why Information Is Not Shared Well In Organizations, Robert C. Kitchen

Theses and Dissertations

The effective use of information in an organization is vital to its success. One of the biggest investments being made today by companies is in their information infrastructures. However, with all of the resources being dedicated to improving information flows, evidence shows that organizations still do not share information as widely as they could or should be. Many studies have been conducted to learn the reasons why people in organizations do not share information as well as would be good. However, no study was found that reported the relative frequency of reported reasons for not sharing information. This paper gathers …

(2) At what point during a Communications and Information officer's career would it be most appropriate to receive training in necessary …

Application Of The Interaction Picture To Reactive Scattering In One Dimension, Michael J. Maclachlan

Theses and Dissertations

The interaction picture is used together with the channel-packet method in a new time-dependent approach to compute reactive scattering matrix elements. The channelpacket method enables the use of the interaction picture for computing reactive S-matrix elements by splitting the computational effort into two parts. First, asymptotic reactant and product wavepackets are individually propagated into the interaction region of the potential to form Moller states. The interaction picture, in contrast to the usual Schrödinger picture of quantum mechanics, is so constructed that a wavefunction that experiences no change in potential (that is, a free-particle wavefunction) remains always fixed, with no translation …

Electrical And Optical Characterization Of Intrinsic And Ion-Implantation Induced Defects In 6h- And 4h-Sic, Michael B. Scott

Theses and Dissertations

Deep level transient spectroscopy (DLTS), Hall effect, and cathodolummescence (CL) measurements are used to characterize the intrinsic and ion-implantation induced defects in high-temperature (475 and 500 °C) ion-implanted epitaxial n-type 6H- and 4H-SiC, ion-implanted with Cr, Mg, Ar, N, and P atoms. Comparison of room-temperature and high-temperature ion-implanted 6H-SiC:Mg and :Cr indicate the significance of high-temperature ion implantation on the activation of the ion-implanted atoms and damage-recovery of the crystalline lattice. The effects of high-temperature annealing on both damage-recovery and implanted ion activation are detected and analyzed, from 1200 to 1800 °C. Trap parameters of both damage-related and species-related defects …

An Assessment Of Mentoring Functions And Barriers To Mentoring, Kristopher A. Singer

Theses and Dissertations

A study of 91 Coast Guard junior officers and their mentors established the construct validity for mentoring functions and barriers to mentoring. The Air Force relies on supervisors to provide mentoring to their subordinates. The key predictors of whether junior officers report their supervisors as mentors were similarity between mentor and mentee and the quality of the supervisory relationship in terms of LMX and psychosocial and career development mentoring functions. The results demonstrated evidence for a compensatory theory of mentoring. Multiple mentors do not have a synergistic effect on mentoring relationships. The key predictors of reporting an additional mentor (other …

Reverse Engineering Of Foreign Missiles Via Genetic Algorithm, Jon D. Wollam

Theses and Dissertations

One mission of the National Air Intelligence Center (NAIC) is the reverse engineering of foreign missile weapon systems from incomplete observational data. In the past, intuition and repeated runs of a missile performance model were required to converge to a solution compatible with observed flight characteristics. This approach can be cumbersome and time consuming, as well as being subject to undesirable influences from the analyst's preconceptions and biases. An alternative approach has been created to apply genetic algorithm (GA) techniques to allow automation of the process, wider exploration of the design space, and more optimal solutions matching the observational data. …

An Environmental History Of The 19th Century Marquette Iron Range, Doug Ottke

Theses and Dissertations

The history of the Marquette Iron Range in the upper peninsula of Michigan is integrally linked to the environment. The natural features of the Marquette Range defined the mode of production on the Range, and conversely, as human systems became more adept in these modes of production they became the most important modifiers of the natural systems.

Settlement on the Marquette Iron Range was closely related to two factors of natural environment: the iron ore formations and the hardwood forest. The distribution of three iron ore formations—principally the Negaunee, but also the Bijiki and other Iron- formations within the Michigamme …
