Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones

Master's Theses

All mammalian females undergo behavioral and neurological changes during pregnancy and motherhood. Many of these changes lead to an enhanced ability to be an effective mother including: increased memory, foraging behaviors, and boldness. Here, we examined the differences in rehearsal strategies between mother and virgin rats. Stops made by rats when exploring their environment have been found to result in reverse replay activity in the hippocampus (Foster & Wilson, 2006). Reverse replay is sequential replay that occurs in the hippocampus immediately after a spatial experience; this replay/activation is in reversed order of the initial spatial episode (Foster & Wilson, 2006). …

Worthless Movement: Agricultural Regression And Mobility, Luiz Costa

Tipití: Journal of the Society for the Anthropology of Lowland South America

Theories of agricultural regression have questioned the standard view that Amazonian foraging represents an ancient adaptation to regional environments by demonstrating that contemporary foragers are former agriculturalists whose historical trajectory led to the adoption of a foraging subsistence strategy. Recent studies have further shown that Amazonian foraging is not an adaptation to a pristine environment, but an engagement with tracts of forest that have been transformed by former agriculturalists. These theories, however, explain the historical process of agricultural loss through an investigation of contemporary foragers or trekkers, as if a certain subsistence strategies and mobile patterns were the inevitable outcome …

The Role Of Multiple Ccaat-Binding Factors In Candida Albicans Gene Expression, Lashall Lynn Bates

Graduate Theses and Dissertations

The CCAAT-binding factor is a heterooligomeric transcription factor that is evolutionarily conserved in eukaryotes. In yeast, the DNA-binding component that interacts with the CCAAT consensus sequence in promoters consists of the subunits termed Hap2p, Hap3p and Hap5p. In yeast and fungi, a fourth subunit, Hap4p, is required for regulating gene expression. The goal of this research is to understand the function of the Candida albicans CCAAT-binding factor and how it relates to virulence and pathogenicity. C. albicans is a human opportunistic pathogen responsible for a variety of mucosal and systemic infections that result in significant morbidity and mortality, particularly in …

Vaccination Nation: A Bioethical Feminist Inquiry Into The Political, Social And Ethical Controversy Surrounding The Human Papillomavirus Vaccine, Kirsten Keller Morin

College of Graduate Studies: Theses & Dissertations

This theoretical inquiry has explored the political, social, and ethical controversy surrounding the government's push to mandate the human papillomavirus (HPV) vaccine for adolescent girls. This vaccine has the potential of preventing cancer, specifically cervical cancer. There is a growing debate in this country whether this new HPV vaccine, Gardasil®, should be added to the list of school-mandated vaccines. Karen Houppert (2007) has stated that this particular "vaccine protects girls and women from cervical cancer and genital warts caused by the human papillomavirus (HPV)" (p. 17). So, what is the controversy? It all started with the fact that this vaccine …

Intersecting Spaces: A Narrative Exploration Of Intersectionality And African American Female School Psychologists, Natasha Vannoy

College of Graduate Studies: Theses & Dissertations

The roles of school psychologists practicing within the public school systems are often defined quantitatively. The focus is often how many students are assessed, what assessment measures provide the most useful snapshots of the students and how the psychometric information will be used for educational planning. Moving away from the numerical aspects of the role, this study examines the narrative voices of the few among many. Reflecting upon the shifting demographics within the field of school psychology, as well as the low number of minority school psychologists within the field, I am examining how African American women within the field …

Pulp Polyp Associated With A Natal Tooth: Case Report, Brian D. Hodgson, Rodney Vergotine, Lance Lambert

School of Dentistry Faculty Research and Publications

Natal teeth are an infrequent occurrence at birth. Often these teeth are extracted because they are very mobile and pose a risk of aspiration. This is a rare case in which a natal tooth was extracted by the pediatrician with his fingers. A root fragment remained and out of this developed a large pulp polyp. This relationship has not been previously reported.

Acute And Subacute Pulmonary Effects Of Diesel Exhaust Particles In Mice: Pathological Changes And Translocation Pathways To The Circulation, Theerayuth Kaewamatawong, Akinori Shimada, Takehito Morita, Wijit Banlunara, Anong Bintvihok

The Thai Journal of Veterinary Medicine

To study the acute and subacute pulmonary effects of diesel exhaust particles (DEPs), mice were intratracheally instilled with 25, 50 or 100 μg of DEPs for dose response experiments. Histological alterations were determined at 3 days post-exposure. 50 or 100 μg of DEPs produced mild to moderate pulmonary inflammation and tissue injury characterized by infiltration of neutrophils and active alveolar macrophages (AMs), focal alveolitis and particle-laden AMs accumulation. Ultrastructural studies of treated animals showed the dissociation of basement membranes and erosion of type I alveolar epithelial cells. To investigate the time response, mice were instilled with 50 μg of DEPs …

The Prevalence Of Osteoarthritis In Wild Vs Captive Great Ape Skeletons, Demelza J. Poe

Anthropology ETDs

This research examined whether the prevalence and skeletal distribution of osteoarthritis (OA) differed between wild and captive great ape skeletons. A secondary, but important, aspect of this research focused on the development of improved aging techniques based on methods commonly used on human osteological samples. Tests were conducted pertaining to the effect that wild versus captive status, sex, and species has on vertebral body lipping, marginal lipping, and eburnation. Age was considered a co-factor. Of the aging methods examined, use of the basilar suture to distinguish between adult and old adult specimens proved to be very imprecise. The ribs and …

Coping Methods And Meaning Making Of Liberian Refugees In The Buduburam Refugee Camp Of Ghana, Abena Gyamfuah Sarfo-Mensah

Honors Scholar Theses

The mental health of war-impacted individuals has been an issue of growing concern to many researchers and practitioners internationally (Miller, Kulkarni, & Kushner, 2006). According to the United Nations High Commissioner for Refugees (2006a), Africans are disproportionately impacted by conflict-related displacement. To date, however, much of the research on the mental health of refugees has been based mostly on Western views of health and trauma. The current study is a mixed-methods investigation of stressors, coping strategies, and meaning making of Liberian refugees in the Buduburam Refugee Camp of Ghana. Results from the Brief COPE, focus groups, and semi-structured ethnographic interviews …

Working Memory, Cues, And Wayfinding In Older Women, Rebecca L. Davis, Barbara A. Therrien, Brady T. West

Peer Reviewed Articles

Individuals create cognitive maps based on relationships between cues in the environment. Older individuals are often impaired in wayfinding, especially in environments that lack distinctive features. This study examines how working memory ability in older women is related to wayfinding performance in the presence of salient (distinctive, prominent) or nonsalient cues. The degree of salient cue complexity is also examined, thus leading to the hypothesis that salient, complex cues are important in wayfinding and that working memory capacity is related to wayfinding performance. The virtual computer-generated arena is used to test this hypothesis in 20 healthy older women in three …

Rainsford Island Shoreline Evolution Study (Rises), Christopher V. Maio

Graduate Masters Theses

RISES conducted a shoreline change study in order to accurately map, quantify, and predict trends in shoreline evolution on Rainsford Island occurring from 1890-2008. It employed geographic information systems (GIS) and analytical statistical techniques to identify coastal hazard zones vulnerable to coastal erosion, rising sea-levels, and storm surges. The 11-acre Rainsford Island, located in Boston Harbor, Massachusetts, consists of two eroded drumlins connected by a low-lying spit. Settled by Europeans in 1636, the Island was later used as the Harbor’s main quarantine station. Previous archeological surveys have identified numerous historically sensitive sites dating to before the Revolutionary War period, including …

Development Of A Coal Reserve Gis Model And Estimation Of The Recoverability And Extraction Costs, Chandrakanth Reddy Apala

Graduate Theses, Dissertations, and Problem Reports (ETD)

The United States has the world largest coal resource and coal will serve as the major and dependable energy source in the coming 200 years or more. However, the amount of recoverable coal reserve depends on the geological formations and quality of the coal seams, future development of mining technology and the extraction cost. A NETL sponsored cooperative research was conducted by the researchers at Carnegie Mallon University (CMU) and West Virginia University (WVU) to estimate the recoverable coal reserve. This thesis presents some of the works that WVU performed to enhance the coal reserve model including characterization of coal …

Pollinator Deception And Plant Reproductive Success In Jack-In-The-Pulpit, Joseph L. Pettit

All-Inclusive List of Electronic Theses and Dissertations

I conducted a study of the deceptive pollination system of Jack-in-the-pulpit (Arisama triphyllum, Araceae) in forests of west-central Indiana. I focused on (a) determining the identities and abundances of insect visitors to spathes, (b) evaluating the success of female spathes in setting fruit, (c) determining the relative importance of pollinator visitation and plant size for fruit number, and (d) investigating the function of the female spathe’s lack of an exit hole, which has been hypothesized to improve pollination success. I found that (a) Jack-in-the-pulpit receives visits from both flies and thrips. Counts of fly corpses from spathes showed the most …

Trade-Offs Between Predation Risk And Forage Differ Between Migrant Strategies In A Migratory Ungulate, Mark Hebblewhite, Evelyn Merrill

Wildlife Biology Faculty Publications

Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an "escape'' from predation, but trade-offs can also occur at finer spatial scales. Previous authors suggest that ungulates will avoid predation risk at the largest scale, although few studies have examined multi-scale trade-offs to test for the relative benefits of risk avoidance across scales. Building on previously developed spatial models of forage and wolf predation risk, we tested for trade-offs at the broad landscape scale and at a finer, within-home-range scale for migratory and …

Attempted Cloning Of A Wnt Gene From Botrylloides Violaceus, Manasa Chandra, James Tumulak

Biological Sciences

Botrylloides violaceus is a colonial ascidian with the ability to undergo sexual and asexual reproduction as well as regeneration. The canonical pathway starts with the extracellular protein Wnt and ends with β-catenin, a transcription factor, which also functions in cell adhesion. The Wnt signaling pathway is involved in embryogenesis and regeneration in a variety of other species. In our studies we attempt to isolate and sequence both a Wnt gene and from Botrylloides via degenerate primer design and PCR. Using bioinformatic methods we aligned sequences from other organisms, as the Botrylloides genome has not yet been sequenced. Using mouse, Ciona, …

Learning Condition-Specific Networks, Sushmita Roy

Computer Science ETDs

Condition-specific cellular networks are networks of genes and proteins that describe functional interactions among genes occurring under different environmental conditions. These networks provide a systems-level view of how the parts-list (genes and proteins) interact within the cell as it functions under changing environmental conditions and can provide insight into mechanisms of stress response, cellular differentiation and disease susceptibility. The principle challenge, however, is that cellular networks remain unknown for most conditions and must be inferred from activity levels of genes (mRNA levels) under different conditions. This dissertation aims to develop computational approaches for inferring, analyzing and validating cellular networks of …

How Values In Scientific Discovery And Pursuit Alter Theory Appraisal, Kevin C. Elliott, Daniel J. Mckaughan

Faculty Publications

Philosophers of science readily acknowledge that nonepistemic values influence the discovery and pursuit of scientific theories, but many tend to regard these influences as epistemically uninteresting. The present paper challenges this position by identifying three avenues through which nonepistemic values associated with discovery and pursuit in contemporary pollution research influence theory appraisal: (1) by guiding the choice
of questions and research projects, (2) by altering experimental design, and (3) by affecting the creation and further investigation of theories or hypotheses. This analysis indicates that the effects of these values are sufficiently complex and epistemically significant to merit further attention.
