Facies Interpretation And Regional Stratigraphic Study Of The Upper Devonian Gordon Zone And Associated Beds In Northern West Virginia And Southwestern Pennsylvania, James H. Moore Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Subsurface correlation of 250 well logs and isopach mapping of Upper Devonian beds across western Pennsylvania and northern West Virginia have been coupled with a core study in Washington County, Pennsylvania, to determine the nature and distribution of the Upper Devonian Gordon zone. The complete stratigraphic section studied includes the Fifth, Fourth, Gordon, Gordon Stray, Thirty Foot, Fifty Foot, and Gantz beds. Along with isopach maps, net sandstone maps were generated for improved characterization of sandstone geometry and facies distribution across the field area. Cross-sections including four west to east and one north to south were constructed to aid in …

Geometry Of Control-Affine Systems, Jeanne N. Clelland, Christopher G. Moseley, George R. Wilkens

University Faculty Publications and Creative Works

Motivated by control-affine systems in optimal control theory, we introduce the notion of a point-affine distribution on a manifold X - i.e., an affine distribution F together with a distinguished vector field contained in F. We compute local invariants for point-affine distributions of constant type when dim(X) = n, rank(F) = n - 1, and when dim(X) = 3, rank(F) = 1. Unlike linear distributions, which are characterized by integer- valued invariants - namely, the rank and growth vector - when dim(X) ≤ 4, we find local invariants depending on arbitrary functions even for rank 1 point-affine distributions on manifolds …

An Organizational Impression Management Perspective On The Formation Of Corporate Reputations, Scott Highhouse, Margaret E. Brooks, Gary J. Gregarus

Research Collection Lee Kong Chian School Of Business

Researchers have only recently turned their attention to the study of corporate reputation.As is characteristic of many early areas of management inquiry, the field is decidedly multidisciplinary and disconnected. This article selectively reviews reputation research conducted mainly during the past decade. A framework is proposed that views reputation from the perspective of organizational impression management. Corporations are viewed as social actors, intent on enhancing their respectability and impressiveness in the eyes of constituents.

Microdeterminants Of Poverty Among The Farming Population In Bangladesh, S Rahman

School of Geography, Earth and Environmental Sciences

This paper examines the determinants of poverty among the farming population of Bangladesh by applying a probit model with heteroscedastic structure (hetprobit). The model diagnostic reveals that the choice of hetprobit instead of a standard probit is more appropriate in this case. Among the socioeconomic factors, land ownership, farm resource endowments and non-agricultural income significantly reduce the probability of becoming poor. On the other hand, the number of dependants and education of female members significantly increase the likelihood of becoming poor. Adoption of green revolution technology does not seem to have any significant influence on the likelihood of being poor. …

Fluorescent Protein Markers To Tag Collagenous Proteins: The Paradigm Of Procollagen Vii, Hye J. Chung, Andrzej Steplewski, Jouni Uitto, Andrzej Fertala

Department of Dermatology and Cutaneous Biology Faculty Papers

Fluorescent proteins are powerful markers allowing tracking expression, intracellular localization, and translocation of tagged proteins but their effects on the structure and assembly of complex extracellular matrix proteins has not been investigated. Here, we analyzed the utility of fluorescent proteins as markers for procollagen VII, a triple-helical protein critical for the integrity of dermal-epidermal junction. DNA constructs encoding a red fluorescent protein-tagged wild type mini-procollagen VII α chain and green fluorescent protein-tagged α chains harboring selected mutations were genetically engineered. These DNA constructs were co-expressed in HEK-293 cells and the assembly of heterogeneous triple-helical mini-procollagen VII molecules was analyzed. Immunoprecipitation …

Empirical Likelihood In Missing Data Problems, Jing Qin, Biao Zhang, Denis H. Y. Leung

Research Collection School Of Economics

Missing data is a ubiquitous problem in medical and social sciences. It is well known that inferences based only on the complete data may not only lose efficiency, but may also lead to biased results if the data is not missing completely at random (MCAR). The inverse-probability weighting method proposed by Horvitz and Thompson (1952) is a popular alternative when the data is not MCAR. The Horvitz–Thompson method, however, is sensitive to the inverse weights and may suffer from loss of efficiency. In this paper, we propose a unified empirical likelihood approach to missing data problems and explore the use …

Human Error In Mining: A Multivariable Analysis Of Mining Accidents/Incidents In Queensland, Australia And The United States Of America Using The Human Factors Analysis And Classification System Framework, Jessica Patterson

All Dissertations

Historically, mining has been viewed as an inherently high-risk industry. Nevertheless, the introduction of new technology and a heightened concern for safety has yielded marked reductions in accident and injury rates over the last several decades. In an effort to further reduce these rates, the human factors associated with incidents/accidents need to be addressed. A modified version of the Human Factors Classification and Analysis System (HFCAS-MI) was used to analyze lost time accidents and high-potential incidents from across Queensland, Australia and fatal accidents from the United States of America (USA) to identify human factor trends and system deficiencies within mining. …

Observations Of Very High Energy Gamma-Ray Emission From Supernova Remnants With Veritas, Mark Theiling

All Dissertations

The nature and source of cosmic rays has been at the core of particle astrophysics since their discovery almost a century ago. The cosmic ray spectrum is best described by a broken power law, and can be better understood as three distinct parts. Theory holds that cosmic rays up to ∼1015 eV – those below the “knee” or steepening in the spectrum – are produced in the shocks of supernova remnants. Direct detection of cosmic rays produced in supernova remnant shocks is impossible, however, as cosmic rays below ∼1018 eV are deflected by the Galactic magnetic field and cannot be …

Job Offer Expectancies: An Analysis Of Antecedents, Outcomes And Moderated Effects, Matthew Millard

All Dissertations

Restricted by limited time and resources, job applicants are often required to make decisions based on their own estimations of an organization's likelihood to extend a job offer. These estimations, or offer expectancies, may be linked to several applicant attitudes and behaviors that have yet to be examined fully in the literature (e.g., job pursuit or information seeking behaviors, search expansion, etc.). We know relatively little about how these perceptions are formed. In this study, actual job applicants were asked to report their perceptions of and behavioral intentions towards organizations that they are currently applying to but have not yet …

Roles, Responsibilities, Celebrations, And Post-Presidency Aspirations Of Female College Presidents, Almeda Jacks

All Dissertations

Of the 3,300 university and college presidents in higher education in the United States, only 23% are held by females (The Chronicle of Higher Education, 2007). The percentage of female students in most institutions in higher education is higher than those of male students.
The Central questions that guided this research study are as follows: What are the roles and responsibilities of presidents of higher educational institutions? How do presidents of higher education celebrate their professional and personal accomplishments? Additionally, what are the post-presidency aspirations of the eight women interviewed who all currently are in their first presidency position in …

A Cognitive Model For Problem Solving In Computer Science, Jennifer Parham

All Dissertations

According to industry representatives, computer science education needs to emphasize the processes involved in solving computing problems rather than their solutions. Most of the current assessment tools used by universities and computer science departments analyze student answers to problems rather than investigating the processes involved in solving them. Approaching assessment from this perspective would reveal potential errors leading to incorrect solutions.
This dissertation proposes a model describing how people solve computational problems by storing, retrieving, and manipulating information and knowledge. It describes how metacognition interacts with schemata representing conceptual and procedural knowledge, as well as with the external sources of …

Towards A Theory On The Sustainability And Performance Of Floss Communities, Mohammad Almarzouq

All Dissertations

With the emergence of Free/Libre and Open Source Software as a significant force that is reshaping the software industry, it becomes more important to reassess conventionally held wisdom about software development. Recent literature on the FLOSS development process suggests that our previously held knowledge about software development might be obsolete. We specifically highlight the tension between the views embodied by the Linus' Law and Brooks' Law.
Linus' Law was forwarded by Eric Raymond and suggests that the FLOSS development process benefits greatly from large numbers of developers. Brooks' Law, which is part of currently held wisdom on software development, suggests …

All Dissertations

This work investigated the production and characterization of novel shaped fibers for fluid adsorption and transport. Shaped fibers such as Y, H, and octolobal, as well as conventional round fibers, were extruded using a research melt extruder. The fibers were extruded from 18 melt flow index (MFI) polypropylene (PP) and blends of 18 MFI PP and 400 MFI PP. Hydrophilic spin finish Bozzetto Favorol SF2 was applied to the surface of extruded fibers and hydrophilic polyester additive LB-100 was included in the blend of some H fibers to increase the hydrophilicity of the fiber surface. The geometric shape retention of …

Gene Expression Profile Of Tumor Cell-Fused Or Noni (Morinda Citrifolia)-Treated Dendritic Cells, Melissa O'Connor

All Dissertations

Dendritic cell-mediated cancer immunotherapy employs several ways to engage tumor antigens. We have demonstrated both in pre-clinical animal studies and early clinical trials that dendritomas, highly purified hybrids between dendritic cells and tumor cells, are superior activators of anti-tumor immunity. In the present study, we examined the expression profile of several inflammatory chemokine and chemokine receptors of dendritomas by RNA microarray and real-time RT-PCR. The results indicate that dendritomas made from immature DCs and tumor cells express higher levels of CCL3, CCL5, and CCL22 and lower levels of CCR2 and CCR5, which mimics LPS matured DCs, while dendritomas made from …

An Analysis Of Working Conditions Of South Carolina Teachers And Expected Working Conditions Of Clemson University Student Teachers, Tammy Bobo

All Dissertations

Results of the 2007-2008 South Carolina inservice teachers' survey were analyzed for levels of reported competence, autonomy, and relatedness in existing working conditions. These results were compared to the expected level of competence, autonomy, and relatedness indicated by preservice teachers in January of 2009 at Clemson University. Levels of existing competence, autonomy, and relatedness reported by inservice teachers in their working conditions were consistently higher than the levels expected by preservice teachers and these differences were found to be significantly different using an analysis of variance.
Themes revealed by principal component analysis showed similarities to the basic needs of competence, …

Synthesis And Development Of Novel Fullerene-Based Structures For Photovoltaics, Electronic Applications And Mri Contrast Agents, Manuel Chaur

All Dissertations

Metallic nitride endohedral metallofullerenes (EMFs) are one of the most interesting types of metallofullerenes due to their high yields and interesting electronic properties. The synthesis of these compounds allows the encapsulation of different metals inside fullerenes making it possible to combine the properties of the metal with those of the fullerene. Their interesting electrochemical and optical features make them potential candidates for several applications such as molecular electronics, biomedical imaging, non-linear optical devices, and magnetic resonance imaging (MRI) agents. This thesis reports the synthesis of novel metallic nitride EMFs based on Gd, Nd, Pr, Ce and La. These families of …

Functional Characterization Of Calcium Dependent Protein Kinase 32 From Arabidopsis, Rucha Karve

All Dissertations

Calcium-dependent protein kinases (CPKs) are major plant Ca2+ sensors, many of which have roles in plant stress responses. The Arabidopsis genome encodes 34 CPK isoforms. Here we report characterization of AtCPK32 gene function. Analysis of transgenic plants expressing pCPK32-GUS shows that CPK32 is highly expressed in roots, pollen and embryo, as well as leaf hydathodes, and the abscission zone of mature siliques. Real time RT-PCR and promoter expression patterns show that CPK32 is responsive to abiotic and biotic stresses. Plants treated with salt, ABA, osmotic stress (PEG), wounding, and flagellin 22 peptide show up-regulation of CPK32 upon these stress treatments. …

School District Superintendents' Response To Ethical Dilemmas: A Grounded Theory, Fay Sprouse

All Dissertations

Ethical dilemmas, situations involving a conflict between values or principles, often arise when employees of school districts violate laws or professional codes of behavior. Ethical dilemmas also occur when there are inequities in educational programming, resulting in missed opportunities for students. This qualitative study, conducted with the grounded theory research methodology, analyzed school district superintendents' responses to ethical dilemmas experienced in the course of their professional career. Critical influences on the decision-making process and the ethical frameworks utilized by participants were examined. A 'Model of Superintendents' Responses to Ethical Dilemmas' was developed and participants' stories were used to elucidate the …

An Investigation On The Use And Flexibility Of Genetic Algorithms For Logistic Regression, Sara Yoder

All Dissertations

Social scientists and other users of large data sets often desire a model to predict the probability that some condition exists, such as the probability that a person has diabetes or that a credit card transaction will be fraudulent. In general, this can be done by data mining techniques, which allow multiple records of data composed of numerous independent variables and one dependent variable to be examined in a statistical fashion to make a predictive model. One particular technique used is logistic regression. Logistic regression forms a predictive model based on a set of independent variables by assigning coefficients to …

Preservice Teacher Attitudes And Intentions Toward An Inclusive Educational Environment: An Application Of The Theory Of Planned Behavior, Julie Jones

All Dissertations

The purpose of this research project was to identify preservice teacher beliefs, attitudes, and intentions toward the inclusion of students with disabilities in a predominately general education environment. A survey instrument was created based on Ajzen and Fishbein's theory of planned behavior and disseminated to three universities in South Carolina. This study improves upon existing studies of preservice teacher attitudes because it takes place at more than one institution and is grounded in a theory that explores the many- layered aspects of attitude.
Preservice teacher attitudes were moderately positive on all measures: behavioral beliefs, subjective norms, and perceived behavioral control. …

Immunohistochemistry In The Diffe‌Rential Diagnosis Of Solitary Thyroid Nodule., Maha Amin, Dina El-Tantawy

Mansoura Medical Journal

Evaluation of solitary thyroid nodule is the most common thyroid problem; the prevalence varies ac­cording to the method of screening used. Solitary thyroid nodule can be caused by any of the thyroid diseas­es; the majority is benign. Lesions characterized by a follicular growth pattern constitute the most common type encountered by pathologists. The vast majority of such lesions do not pose difficulties for histopathologi-cal interpretation. A subset of these tumors, however, can represent a se­rious challenge for diagnosis, man­agement & fall under the "indetermi­nate" category. Thyroid tumors with follicular growth pattern include a broad range of lesions that range from …
