Central Mechanisms Regulating Pituitary-Adrenal Activity In Infant Guinea Pigs (Cavia Porcellus) During Exposure To Psychological Stressors: Independent And Combined Effects Of Maternal Separation And Novelty, Deborah Suzanne Maken

Browse all Theses and Dissertations

Separation from the maternal attachment figure, particularly when it occurs in a novel or threatening environment, reliably increases pituitary-adrenal activity in a number of species, and is thought to increase later susceptibility to psychopathology in humans. However, little is known about the central mechanisms mediating these effects. Therefore, I investigated cortisol and ACTH levels in plasma, corticotropin-releasing factor (CRF) mRNA expression in the hypothalamic paraventricular nucleus (PVN), and c-Fos activity in a circuit [medial amygdala (MeA)- bed nucleus of the stria terminalus (BNST)] thought to drive pituitary-adrenal activity during exposure to psychological stressors, as well as in the PVN. Measurements …

Genetic Differentiation In Ambystomatid Salamanders Across A Fragmented Landscape, Joseph E. Bartoszek

Browse all Theses and Dissertations

It is generally recognized that amphibian populations declining across the globe. Habitat loss is the primary cause of decline. The salamander family Ambystomatidae has experienced significantly more rapid decline than the average for amphibians. Coefficients of Conservatism (CoC) have been developed for amphibians in Ohio. These are based primarily on habitat requirements with high CoCs for amphibians with stringent habitat requirements (e.g. vernal pools associated with large, intact, undisturbed forest), and low CoCs for amphibians with less stringent habitat requirements. Genetic diversity in five species and one hybrid complex of ambystomatid salamander in southwest Ohio were examined and compared to …

Interfacial Modification Of Microcellular Carbon: Influence Of Ceramic And Carbon Nanotube Coatings, Anil Kumar Karumuri

Browse all Theses and Dissertations

Microcellular carbon is an emerging ultra lightweight and efficient thermal management material, which also has great potential as a reinforcement material for selected composites. However, these porous materials exhibit relatively low mechanical properties, and are susceptible to degradation in oxidizing environment. The scope of this research is to investigate surface modification approaches that can address these issues. Two specific objectives were: (1) to develop ceramic coatings to improve the survivability of carbon foams in high temperature applications, and (2) to develop and test modifications that can improve cellular composites involving carbon foam. It was seen that a mixed layer of …

Impact Of Wastewater Fouling On Contact Angle, Evan Thomas, Dean Muirhead

United States National Aeronautics and Space Administration: Publications

Capillary dependent systems are highly influenced by surface fouling and may degrade as material surface properties change. In anticipation of a spacecraft microgravity fluids management system exposed to highly variable wetting conditions, the impact of urine wastewater fouling on capillary contact angle was examined. The results indicate that, in general, surface fouling can decrease the contact angle when crystalline structures or biofilms form. Small crystalline growth on the order of 10 µm can lower advancing contact angles θ_adv by approximately 30˚, while biofilm growth can lower it by approximately 15˚. Vacuum drying of fouled surfaces increased θ_adv by …

Structural Relations Among Negative Affect, Mate Value, And Mating Effort, Beth Randi Kirsner, Aurelio Jose Figueredo, W. Jake Jacobs

Faculty Articles

We compared the ability of models based on evolutionary economic theory and Life History (LH) Theory to explain relations among self-reported negative affect, mate value, and mating effort. Method: Two hundred thirty-eight undergraduates provided multiple measures of these latent constructs, permitting us to test a priori predictions based on Kirsner, Figueredo, and Jacobs (2003). We compared the fit of the initial model to the fit of five alternative theory-driven models using nested model comparisons of Structural Equations Models. Rejecting less parsimonious and explanatory models eliminated the original model. Two equally parsimonious models explained the data pattern well. The first, based …

The Influence Of Temperature On Population Growth And Allergen Production In Cultured House Dust Mites - Dermatophagoides Pteronyssinus And Dermatophagoides Farinae, Lakshmi Yella

Browse all Theses and Dissertations

Dermatophagoides pteronyssinus and Dermatophagoides farinae are commercially cultured to produce materials to make extracts for diagnostic tests and immunotherapy. There is some speculation as to how the culture conditions such as time of culture, temperature, relative humidity and food might influence the mite populations and subsequent production of allergens. The purpose of our investigation was to see how temperature influenced the population growth and allergen production of cultured house dust mites. D. pteronyssinus and D. farinae were cultured at 20°C and 25°C. Samples were collected at two week intervals for live mite count, life stage composition and to determine Group …

Pedagogical Re-Mediation In Hybrid Courses: A Case Study Of Five First-Year Composition Instructors, Rebecca Middlebrook

Electronic Theses and Dissertations

As the move to increase availability of composition courses in the online environment continues, it is important to understand the ways in which composition instructors have taken on the challenges associated with moving their teaching online and how they modify, or re-mediate, their pedagogy for the this new teaching and learning environment. This study takes on the task of examining re-mediation as it occurs in the pedagogical practices used by instructors to facilitate peer review activities in hybrid, first-year composition courses. At the same time, it is important to understand the varying factors that may influence the degree to which …

Transfusion Related Acute Lung Injury--Trali: An Under Diagnosed Entity, Bushra Moiz, Hasanat Sharif, Fauzia Ahmad Bawany

Department of Pathology and Laboratory Medicine

Transfusion related acute lung injury (TRALI) is a life-threatening complication of transfusion of blood and its components resembling acute respiratory distress syndrome (ARDS) or acute lung injury (ALI). TRALI is a particular form of ARDS that follows blood transfusion and is caused by donor-derived antibodies present in the transfused products, reacting with the recipients' blood cells, inducing release of inflammatory mediators thus compromising lung functions. Anti-HLA antibodies are the most frequently indicted inducers in this category. Literature search has not revealed any documented case of TRALI from Pakistan. This in no way implies that TRALI is non existent in this …

"Zum Einsatz Des Leben Fuer Deutschland": Girls' Popular Fiction During The Third Reich, Kathryn L. Payne

Dissertations, Theses, and Capstone Projects

Recent research in the field of Cultural Studies has shown that popular fiction, more than any other genre, provides a way for readers to regulate and structure their lives. The purpose of the present study is to investigate the popular fiction which girls living in Nazi Germany read in an attempt to see how current events and policies are reflected in the novels in an effort to acclimatize girls to life under National Socialism and gain their complete support of the Third Reich. Popular fiction was expected to portray a mirror of life for young readers under National Socialism, with …

Divided Men: The Masculinity/Marriage Dilemma In The Novels Of George Eliot, Danny Sexton

Dissertations, Theses, and Capstone Projects

Studies of Victorian masculinities have been primarily concerned with how men defined and were defined within the public sphere. This limited focus has ignored their private and domestic lives, itself an exemplification of the separate sphere theory. This dissertation explores what I called the masculinity/ marriage dilemma, a situation in which men feel that they must choose between a public life and a private one. George Eliot's male characters are divided, feeling themselves pulled in what they perceived as two different routes towards manhood. Related to this predicament are issues of power, particularly between men and women, men and other …

Beyond Observation: Literature And Science In Kafka, Rilke, Mann And Musil, Katya Ilina

Dissertations, Theses, and Capstone Projects

The relationship between science and literature is an expanding area of scholarly interest which remains underrepresented within the field of Germanistik. This dissertation will attempt to close the gap by focusing on the interactions between the selected works of Franz Kafka, Rainer Maria Rilke, Thomas Mann, and Robert Musil, and the scientific outlooks which began to emerge in the nineteenth century primarily by focusing on the concept of observation. Observation is a concept important for the period of my investigation because it signified a major shift in consciousness. The prior facile division into impartial experimenter and observed phenomenon, so characteristic …

Structural Studies Of Biopolymers Using Computer Simulations, Optical And Magnetic Spectroscopy, Subhasish Chatterjee

Dissertations, Theses, and Capstone Projects

Biopolymers are essential components of numerous natural and synthetic macromolecular assemblies. In the present study, the structural properties of biopolymers ranging from fungal melanins to synthetic nucleic acids were investigated using spectroscopic methods and theoretical modeling. (1) Computational modeling and molecular dynamics simulations were used to study the structural properties of a short single-stranded (ss) DNA. The dependence of the conformational stability and flexibility of the ssDNA on the thermodynamic conditions of the system was demonstrated. (2) Time-resolved fluorescence spectroscopy involving an organic donor-quencher pair was utilized to study the conformational properties of Y-shaped DNA. Results highlighted the different distances …

Anger Et Cetera: Understanding The Emotions In Ethics, Damien Dupont

Dissertations, Theses, and Capstone Projects

This dissertation argues in part that because the ethical theory of sentimentalism is based on the mistaken belief that emotions are non-cognitive, sentimentalism cannot account for the fact of the influence of cognition in morality and moral action. Therefore sentimentalism is of little use in ethics.

This work is done by going back to examine Western thinking on the emotions from its dawn in Homer's writing through to contemporary philosophy and neurophysiology on the emotions. Following the development of the way emotions were thought of and how they related to ethics allows the identification of an intellectual forked path brought …

Youth In Out-Of-Home Care: The Question Of Psychological Agency, Lauren M. Polvere

Dissertations, Theses, and Capstone Projects

This dissertation examines the critical perspectives of formerly institutionalized youth with psychiatric disabilities through the lens of psychological agency. Framed in sociohistorical perspective, a theoretical shift is suggested for understanding the development of youth with mental health placement histories. In contrast to clinical approaches, which focus on psychopathology of youth in placement, this study elucidates the agentic meaning making processes employed by youth as they negotiate various treatment contexts and engage in activism. Participants in the study are 12 youth between the ages of 16-23, who are involved in peer-run groups for young people with out-of-home treatment experience, and 4 …

The absorption behavior of Carbon dioxide from flue gases can be studied using conventional absorber and polymeric hollow fiber membrane contractors. An industrial absorber data was compared with simulated data using hollow fiber membrane contractor using the gPROMs software package. In this analysis, with …

The Germination Ecology And Composition Of The Indigenous Seeds Of Cyprus Conglomeratus: A Sand Dune Binder, Sheikha Saeed Amer Al Neyadi

Theses

Cyperus conglomeratus is among few species that tolerate the instability of sand dunes and its low nutrients. This species tolerates grazing animals and sand burial. It is considered as a good fodder for both domestic and wildlife animals. It has the potential to fix sand dunes. In addition, a preliminary observation indicated the presence of high contents of oil in the seeds. Despite the ecological importance of C. conglomeratus, little information is available about germination behaviour and seed composition. The present study assessed the dormancy, germination requirement, tolerance to salinity and drought during germination stage, the impact of dormancy regulation …

Irreconcilable Differences? The Troubled Marriage Of Science And Law, Susan Haack

Law and Contemporary Problems

There haven't always been scientific witnesses: in fact, there haven't always been witnesses. In early medieval times, courts relied on tests by oath, ordeal, and sometimes by combat. Here, Haack provides a brief historical background to the use of scientific experts in law and then proceeds to discuss in greater detail the values underlying scientific inquiry, the uncertainty in the quest of knowledge and understanding, and the methods by which consensus is reached, even if that consensus is always tentative. She then contrasts scientific inquiry with the law's quest for "truth" in the courtroom and, particularly, the normative and temporal …

Science, Law And The Expert Witness, Joseph Sanders

Law and Contemporary Problems

Expert witnessing is a particularly useful place to observe the clash of legal and scientific conventions because it is here that one group of people (scientific experts) who are integrated into one set of conventions are challenged by the expectations of a different set of conventions. Here, Sanders looks at how legal conventions affect the behavior of expert witnesses when they appear in court in both criminal and civil cases. He also reviews differences in scientific and legal conventions as they apply to expert knowledge and discusses two central reasons for these differences: adversarialism and closure.

How Much Evidence Is Enough? Conventions Of Causal Inference, David Kriebel

Law and Contemporary Problems

One of the most important issues for science in the courtroom is the determination of causality. Like science in the courtroom, science in the regulatory arena can also bring a clash of cultures, misunderstanding, and controversy--especially when decisions must be made with some urgency with interested parties watching closely. Here, Kriebel discusses some conventions in the conduct of science and in the ways that scientific information is communicated to nonscientists that can make it difficult for judges, lawyers, regulators, and politicians to do their jobs making decisions about complex environmental and health issues.

Trials And Tribulations: What Happens When Historians Enter The Courtroom, David Rosner

Law and Contemporary Problems

In recent years, historians have been brought into legal cases in unprecedented numbers. As the courts have tried to adjudicate responsibility for environmental and occupational diseases, history has played an increasingly central role in decisions that affect the cases themselves and in social policy regarding risk. In suits over tobacco-related diseases, asbestosis, radiation, and other toxic substances, more historians of technology and science, social history, and public health are being sought to provide testimony aimed at assessing responsibility for damages that have arisen years--sometimes decades--after exposure. Here, Rosner traces the use of historians as experts in litigation.

Rethinking Visitation: From A Parental To A Relational Right, Ayelet Blecher-Prigat

Duke Journal of Gender Law & Policy

[...] visitation rights are considered to arise from the very fact of parenthood, so that parents are entitled to this right simply by being legally recognized as parents. [...] visitation rights are subject to the general rule of parental exclusivity: only a child's legal parents have rights considered parental, and non-parents cannot acquire them.

A Man’S Right To Choose His Surname In Marriage: A Proposal, Michael Mahoney Frandina
