Women's Body Image, Patriarchy, And Photography: A Pictorial Content Analysis Of National Geographic's Representation Of Women., Kathryn D. Newhouse
Graduate Theses, Dissertations, and Problem Reports (ETD)
Women have been depicted within media outlets such as magazines as domestic caretakers for generations. While history has at times been positive in its representation of women, especially during World War II and the government’s plea for women to work in industry, the vast majority of media outlets after the war again created the housewife image from the years before the war for women to follow. The popular governmental posters with “Rosie the Riveter” stating, “We Can Do It!” were replaced with images of a happy wife tending house for her husband fresh from the war. While the posters were …

The Use Of Β-Actin Mrna Degradation To Estimate Bloodstain Age, Kristin Nicole Nestor
The Use Of Β-Actin Mrna Degradation To Estimate Bloodstain Age, Kristin Nicole Nestor
Graduate Theses, Dissertations, and Problem Reports (ETD)
The time of deposition of biological samples at a crime scene is vital for interpreting the value of the samples in cases where the location by itself is not incriminating. Previous work from our laboratory showed a method to estimate the bloodstain age by using reverse transcription real-time PCR based on the amount of RNA decay of 18S compared to β-actin. In order to eliminate variability in expression levels between 18S and β-actin, an approach utilizing two differently sized regions of the β-actin gene was investigated. Results indicated ethnicity, age, and gender of the individual from whom the blood was …

The explanatory variables were based on those identified in computer, Internet, and e-commerce adoption studies as well as variables specifically related to direct marketing farms. The similar results of both the Probit and Logit models indicated that farm businesses that have adopted the use of websites have higher gross farm sales, advertise using more methods, sell less perishable …
Surrendered Resistance: Playing Dead In American Autobiographical Writing, 1840-1933., Georgia R. Kreiger
Surrendered Resistance: Playing Dead In American Autobiographical Writing, 1840-1933., Georgia R. Kreiger
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation focuses on the use of death as a metaphor for lived experiences in nineteenth- and early twentieth-century American autobiographical writing. Adopting Paul de Man’s definition of autobiography as a figure of reading rather than a genre or mode, the study analyzes autobiographical death acts in a variety of writings, including political discourse, fiction, and poetry. The writers discussed stage deaths-of-the-self to facilitate descriptions of traumatic events that might otherwise defy verbal expression. They “play dead†figuratively in their texts, similarly to the way one might play dead literally as a survival strategy in the presence of an animal …

Error Resilient Transmission Of Three-Dimensional Dct Coded Video., Supriya Dilip Sawant
Graduate Theses, Dissertations, and Problem Reports (ETD)
Current multimedia applications involve video transmission over unprotected noisy channels where the video stream is contaminated with errors thereby requiring advanced error concealment/correction strategies. Our objective in this research is to devise error resilient strategies that will help combat channel errors and produce a quality video reconstruction. In this thesis we investigate two error resilient techniques, namely, unequal error protection (UEP) and multiple description coding (MDC) for video transmission. Unlike the traditional video coding system that uses two dimensional transformations accompanied with motion estimation and compensation, we focus on the three dimensional discrete cosine transform (3D DCT). We propose video …
Validation Of Nitrogen Oxides And Pm Correction Factors For Heavy Duty Diesel Engines., Mahesh Govindareddy
Validation Of Nitrogen Oxides And Pm Correction Factors For Heavy Duty Diesel Engines., Mahesh Govindareddy
Graduate Theses, Dissertations, and Problem Reports (ETD)
Considering the contribution of oxides of nitrogen (NOx) from on-road heavy duty diesel engines to the atmospheric inventory, their accurate measurement is important. According to the Code of Federal Regulations Title 40 Part 86 Subpart N, NOx measured at a given temperature and relative humidity is corrected to standard conditions using a humidity correction factor. This factor depends on the intake air absolute humidity. However, this correction factor was developed in the 1970’s and may not be applicable to the existing engine technologies. Also, after the 1998 Consent Decrees, in-use testing has become a part of engine certification and the …
Characterization Of A Catalase Gene Associated With Ergot Alkaloids In Aspergillus Fumigatus, And, Studies On An Alternate Lysergyl Peptide Synthetase Gene And Ergopeptine In Neotyphodium Coenophialum., Kerry E. Goetz
Graduate Theses, Dissertations, and Problem Reports (ETD)
Ergot alkaloids, a category of mycotoxins produced by various fungi, adversely affect both humans and animals. Several plant-associated fungi in the genera Claviceps, Neotyphodium, and Epichloe (order Hypocreales) produce an array of ergot alkaloids. Another fungus, Aspergillus fumigatus that occupies a completely different ecological niche and is classified under the order Eurotiales, also produces ergot alkaloids. The gene clusters predicted to encode the enzymes required for ergot alkaloid production within these species are strikingly similar, however, they are poorly understood. In this study, a gene knockout of the easC gene that encodes a putative catalase resulted in the loss of …
Filling The Silence --An Iserian Reading Of Ilse Aichinger's Work, Julia Sonja Brassat
Filling The Silence --An Iserian Reading Of Ilse Aichinger's Work, Julia Sonja Brassat
Graduate Theses, Dissertations, and Problem Reports (ETD)
The works of the Austrian writer Ilse Aichinger are often considered impenetrable and incomprehensible. Aichinger’s doubt about conventional language serves as the basis for her use of highly pictorial and complex linguistic constructions. Although many literary scholars have alluded to the impenetrability of Aichinger’s works, few attempts have been made to investigate the meaning of her texts. In his theory of aesthetic response, Wolfgang Iser explains that literary works contain vacancies in the system of the text that need to be filled by the reader’s imagination. They serve as an impetus for the reader, during the process of reading, to …

Active Inaction: Symbolic Politics, Agenda Denial Or Incubation Period. Twenty Years Of United States Workplace Violence Research And Prevention Activity., Eleanor Lynn Watson Jenkins
Graduate Theses, Dissertations, and Problem Reports (ETD)
Workplace violence has always existed in the U.S.---indeed, during some periods of our history, fear, intimidation, and physical violence were commonplace in work settings. Contemporary expectations in industrialized democracies, however, are that all workers are entitled to a workplace free from recognized hazards. During the time period from the mid 1980s to the present, a range of actors from local, state, and Federal government, industry, labor, academic, as well as professional societies and organizations became active in the area of workplace violence. Government efforts have stopped short of regulatory efforts with an emphasis instead on symbolic and learning tools. The …

Empirical Analysis Of Software Reliability, Margaret L. Hamill
Empirical Analysis Of Software Reliability, Margaret L. Hamill
Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis presents an empirical study of architecture-based software reliability based on large real case studies. It undoubtedly demonstrates the value of using open source software to empirically study software reliability. The major goal is to empirically analyze the applicability, adequacy and accuracy of architecture-based software reliability models. In both our studies we found evidence that the number of failures due to faults in more than one component is not insignificant. Consequently, existing models that make such simplifying assumptions must be improved to account for this phenomenon. This thesis' contributions include developing automatic methods for efficient extraction of necessary data …

Predicting Inflation, And The Relationship Between Financial Integration, Financial *Development And Economic *Growth, Lillian T. Kamal
Graduate Theses, Dissertations, and Problem Reports (ETD)
Three essays are presented. The first essay re-visits the P* model (developed by Hallman, Porter and Small, 1991) with an application to US data. The central idea behind the P* model is that the price level is determined by the money stock, output and velocity. This study brings together criticisms of the P* model together in an attempt to address the major concerns with an improvement upon the existing model. A horse race is then run between the original P* model, two variant P* models, and three other models---an atheoretic naive AR process and an ARMA process as well as …
Enlightened Defense: The National Security *Policy Of Thomas Jefferson, Robert R. Leonhard
Enlightened Defense: The National Security *Policy Of Thomas Jefferson, Robert R. Leonhard
Graduate Theses, Dissertations, and Problem Reports (ETD)
The triumph of Thomas Jefferson and the Democratic Republicans in 1800 left the deposed Federalists aghast at what this Francophile, anti nationalist, reputedly atheistic president might do to the country. Despite Jefferson's impulses toward pacifism, national isolation, the diffusion of political power, and healing faction, the eight years of his two administrations were destined to be as calm as a hurricane. The turbulent situation in Europe had already made a mockery of Washington's advice to avoid entanglement, and during Jefferson's presidency, the dangers only increased.;Jefferson's ideas on national security were diametrically opposed to those of Alexander Hamilton and the Federalists. …
Transactional Distance And Student Motivation: Student Perception Of Teacher Immediacy, Solidarity Toward Peer Students And Student Motivation In Distance Education, Hye Yoon Jung
Graduate Theses, Dissertations, and Problem Reports (ETD)
Transactional Distance Theory is conceptually significant in that the core nature of distance in distance education is not a geographical or temporal distance but a psychological or communicational distance between students and their teacher(s), as well as among students. In spite of the conceptual significance of the transactional distance theory, the interrelationships among the construct variables and propositions of the theory are unclear. The majority of studies on transactional distance theory either used the theory solely as a conceptual framework, or proposed the refinement of the theory. Literature review indicated that the theory was found to be invalid and unreliable. …
Does Physical Disability Truly Create Impairment In Adjustment To College Life?, Jennifer R. Hurst
Does Physical Disability Truly Create Impairment In Adjustment To College Life?, Jennifer R. Hurst
Graduate Theses, Dissertations, and Problem Reports (ETD)
This research utilized a mixed methods design to explore the differences between students with and without disabilities in perceived social support, coping style, self efficacy, and college adjustment. In addition, the influence of athletic participation on the above variables was examined in the sub-sample of students with disabilities. Neither survey nor interview results supported any differences between students with disabilities and students without disabilities on the study variables. Results suggested that discrepancies in college outcome variables (i.e. matriculation and persistence) were not a result of differences in disability status, but are the result of differences in adjustment, perceived social support, …

Classification Of Dental X-Ray Images, Usman Qureshi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Forensic dentistry is concerned with identifying people based on their dental records. Forensic specialists have a large number of cases to investigate and hence, it has become important to automate forensic identification systems. The radiographs acquired after a person is deceased are called the Post-mortem (PM) radiographs, and the radiographs acquired while the person is alive are called the Ante-mortem (AM) radiographs. Dental biometrics automatically analyzes dental radiographs to identify the deceased individuals. While, ante mortem (AM) identification is usually possible through comparison of many biometric identifiers, postmortem (PM) identification is impossible using behavioral biometrics (e.g. speech, gait). Moreover, under …

Lossless Compression Of Hyperspectral Images, Sushil Kamalchand Jain
Graduate Theses, Dissertations, and Problem Reports (ETD)
Band ordering and the prediction scheme are the two major aspects of hyperspectral imaging which have been studied to improve the performance of the compression system. In the prediction module, we propose spatio-spectral prediction methods. Two non-linear spectral prediction methods have been proposed in this thesis. NPHI (Non-linear Prediction for Hyperspectral Images) is based on a band look-ahead technique wherein a reference band is included in the prediction of pixels in the current band. The prediction technique estimates the variation between the contexts of the two bands to modify the weights computed in the reference band to predict the pixels …

Thirty-seven microsatellites were identified by screening 576 clones from TAGA and ATG-repeat …
Signaling Pathways Involved In Regulation Of Glucose -6 -Phosphate Dehydrogenase (G6pd) By Arachidonic Acid, Indrani Talukdar
Signaling Pathways Involved In Regulation Of Glucose -6 -Phosphate Dehydrogenase (G6pd) By Arachidonic Acid, Indrani Talukdar
Graduate Theses, Dissertations, and Problem Reports (ETD)
Glucose-6-phosphate dehydrogenase (G6PD) is the rate-limiting enzyme of pentose phosphate pathway and provides NADPH for de novo fatty acid biosynthesis. For the later reason, G6PD is known as a lipogenic enzyme. Insulin induces expression of G6PD mRNA via activating the PI3 kinase pathway in primary rat hepatocytes. Addition of arachidonic acid, a polyunsaturated fatty acid, in the medium interferes with the PI3 kinase pathway, and thus inhibits the insulin-mediated induction of G6PD. Arachidonic acid in the presence of insulin induces p38 MAP kinase pathway over insulin treatment alone. Activation of p38 MAP kinase by arachidonic acid interferes with the insulin …
