Spatial Analysis Of Factors Influencing Long-Term Stress In The Grizzly Bear (Ursus Arctos) Population Of Alberta, Canada, Mathieu Bourbonnais, Trisalyn Nelson, Mark Cattet, Chris T. Darimont, Gordon Stenhouse
Physiology Collection
Non-invasive measures for assessing long-term stress in free ranging mammals are an increasingly important approach for understanding physiological responses to landscape conditions. Using a spatially and temporally expansive dataset of hair cortisol concentrations (HCC) generated from a threatened grizzly bear (Ursus arctos) population in Alberta, Canada, we quantified how variables representing habitat conditions and anthropogenic disturbance impact long-term stress in grizzly bears. We characterized spatial variability in male and female HCC point data using kernel density estimation and quantified variable influence on spatial patterns of male and female HCC stress surfaces using random forests. Separate models were developed for regions …

The Effects Of Acute Post Exercise Consumption Of Two Cocoa-Based Beverages With Varying Flavanol Content On Indices Of Muscle Recovery Following Downhill Treadmill Running, Katelyn Peschek, Robert Pritchett, Ethan Bergman, Kelly Pritchett
All Faculty Scholarship for the College of the Sciences
Dietary flavanols have been associated with reduced oxidative stress, however their efficacy in promoting recovery after exercise induced muscle damage is unclear. This study examined the effectiveness of acute consumption of cocoa-flavanols on indices of muscle recovery including: subsequent exercise performance, creatine kinase, muscle tenderness, force, and self-perceived muscle soreness. Eight endurance-trained athletes (VO2max 64.4 ± 7.6 mL/kg/min) completed a downhill running protocol to induce muscle soreness, and 48-h later completed a 5-K (kilometer) time trial. Muscle recovery measurements were taken at PRE, 24 h-POST, 48 h-POST, and POST-5K. Participants consumed 1.0 g of carbohydrate per kilogram of body weight …
The Effects Of Ecological Context And Individual Characteristics On Stereotyped Displays In Male Anolis Carolinensis, Catherine Policastro
The Effects Of Ecological Context And Individual Characteristics On Stereotyped Displays In Male Anolis Carolinensis, Catherine Policastro
University of New Orleans Theses and Dissertations
Displays are ubiquitous throughout the animal kingdom. While many have been thoroughly documented, the factors affecting the expression of such displays are still not fully understood. We tested the hypotheses that display production would be affected by ecological context (i.e. the identity of the receiver) and intrinsic qualities of the signaler (i.e. heavyweight and lightweight size class) in the green anole lizard, Anolis carolinensis. Our results supported these predictions and show that a) ecological context, specifically displaying to conspecifics, has the greatest impact on display production; b) size class influenced display rate with heavyweight males displaying more to green …
Dose Dependent Effects Of Caffeine On Cognitive Performance And Neuronal Activation, Stephan Albrecht, Helen Morris, Michelle Vieyra
Dose Dependent Effects Of Caffeine On Cognitive Performance And Neuronal Activation, Stephan Albrecht, Helen Morris, Michelle Vieyra
Journal of the South Carolina Academy of Science
Many students assume that the more caffeine you drink, the better your cognitive performance. Over-consumption of caffeine has many negative effects, so if there are no dose related cognitive benefits to large amounts of caffeine, then college students should limit their intake. This study looked at whether ingesting a medium dose (200 mg) versus a lower dose (100 mg) of caffeine improved short term memory as measured by Flanker and n-back tests, compared to a control group. In addition, we looked at whether larger doses of caffeine produced a difference in neuronal activation during these tests as measured by functional …

Enrichment And Training Improve Cognition In Rats With Cortical Malformations, Kyle R. Jenks, Marcella M. Lucas, Ben A. Duffy, Ashlee A. Robbins, Barjor Gimi, Jeremy M. Barry, Rod C. Scott
Dartmouth Scholarship
Children with malformations of cortical development (MCD) frequently have associated cognitive impairments which reduce quality of life. We hypothesized that cognitive deficits associated with MCD can be improved with environmental manipulation or additional training. The E17 methylazoxymethanol acetate (MAM) exposure model bears many anatomical hallmarks seen in human MCDs as well as similar behavioral and cognitive deficits. We divided control and MAM exposed Sprague-Dawley rats into enriched and non-enriched groups and tested performance in the Morris water maze. Another group similarly divided underwent sociability testing and also underwent Magnetic Resonance Imaging (MRI) scans pre and post enrichment. A third group …
Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng
Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng
Dartmouth Scholarship
Abstract Bruce and Young (1986) proposed a model for face processing that begins with structural encoding, followed by a split into two processing streams: one for the dynamic aspects of the face (e.g., facial expressions of emotion) and the other for the invariant aspects of the face (e.g., gender, identity). Yet how this is accomplished remains unclear. Here, we took a psychophysical approach using contrast negation to test the Bruce and Young model. Previous research suggests that contrast negation impairs processing of invariant features (e.g., gender) but not dynamic features (e.g., expression). In our first experiment, participants discriminated differences in …

The Impact Of Selected Socioeconomic Factors On Asset Building In Rural Communities, Nii O. Tackie, Judith N. Aboagye, Gwendolyn J. Johnson, Millicent Braxton, Latanya Hunt-Haralson, Gertrude D. Wall
Professional Agricultural Workers Journal
The study examined the impact of selected socioeconomic factors on asset building. Using a questionnaire, data were obtained from a convenience sample of 204 participants from several Alabama Black Belt Counties, and analyzed using descriptive statistics and logit analysis. The results showed that a majority (64%) was willing to participate in an asset building program. Of this, an overwhelming majority (at most 70%) wanted to set up a small business; further their education, or purchase a home. In addition, one socioeconomic factor, age, had a statistically significant (p = 0.016) effect on willingness to participate in an asset building …
Community-University Partnerships For Change In The Black Belt South, Rosalind Harris
Community-University Partnerships For Change In The Black Belt South, Rosalind Harris
Professional Agricultural Workers Journal
This article explores issues related to community-university partnerships by examining
the unfolding of the Black Belt Initiative, a 21st century mobilization within the Black Belt South to establish a Black Belt Regional Commission. The Black Belt Initiative provides an instructive and compelling case study. For instance, the very nature of the Black Belt Initiative’s beginnings through the provision of a grant by Senator Zell Miller of Georgia to the University of Georgia with the proviso that “poverty – not race be the guiding principle…” heightened the tension between historically black and white universities reflecting longstanding contestations around how problems …

Socially Disadvantaged Farmer Issues Can Be Addressed When Diverse Frontline Agricultural Workers Proactively Work Together, Walter A. Hill, Jillian Hishaw, Tasha M. Hargrove
Professional Agricultural Workers Journal
This paper focuses on socially disadvantaged farmers (SDFs) and civil rights issues as it relates to the USDA. It also deals with Diversity Initiatives in the 2008 Farm Bill, and discusses an assessment by Jackson Lewis LLC of the USDA’s efforts to deal with the diversity initiatives. Redacted USDA case studies examined at the 2010 Professional Agricultural Workers Conference at Tuskegee University are presented. The findings revealed that at that time the 2008 Farm Bill Initiatives were not effectively being implemented. It was recommended that the USDA should: keep making the effort to reform or improve its civil rights practices; …

Seasonal Variation On General Composition, Free Amino Acids And Fatty Acids In The Gonad Of Taiwan's Sea Urchin Tripneustes Gratilla, Yu-Chun Chen, Tai-Yuan Chen, Tze-Kuei Chiou, Deng-Fwu Hwang
Journal of Marine Science and Technology
The seasonal variation of chemical composition in sea urchin Tripneustes gratilla gonad from Taiwan is investigated. The level of both gonad index (GI) and body weight in the sea urchins showed seasonal variations and were higher during spring and summer. The main saturated fatty acids (SFA) of sea urchin gonad were C14:0 and C16:0, and both varied with season. Arachidonic acid and eicosapentaenoic acid were the dominant poly-unsaturated fatty acids (PUFA), while C16:1, C18:1 and C22:1 were the predominant monoenoic fatty acids (MFA). The levels of total fatty acids were higher in summer, and decreased to the lowest in December …

Age And Growth Study Of The Jack Mackerel (Trachurus Japonicus) In The Northeatern Waters Off Taiwan, Hsueh-Jung Lu, Chih-Chun Chen, Jen-Chia Cheng
Journal of Marine Science and Technology
Jack mackerel (Trachurus japonicus) is one of the most important fish resources in the northeastern Taiwan. Because of the flourishing of Taiwanese seiner fisheries in recent years, the proportion and catch of jack mackerels have increased. However, the studies on their age and growth are outdated, thus data on the catch-at-age composition are lacking. The present study collected jack mackerel otolith samples from May, 2010, to April, 2011, for age determination and combined those data with length and weight data from 2005 to January, 2012, to investigate the catch-at-age of jack mackerel in the northeastern waters off Taiwan. The regression …
Alzheimer's Disease And Circadian Rhythms In A Drosophila Model, Lauren Alejo
Alzheimer's Disease And Circadian Rhythms In A Drosophila Model, Lauren Alejo
Honors Theses
Sleep disorders are commonly reported in Alzheimer's disease, a debilitating, age-related neurodegenerative disorder that affects neurons in the brain. Recently, several studies have suggested a role for sleep abnormalities and the internal "body clock" known as the circadian system, in the disease onset and progression. Since most of the data has been collected from mammals with complex neural circuitry, the molecular and cellular mechanisms that integrate the two neural networks are still limited. This study examined the relationship between circadian rhythmicity and Alzheimer's Disease presentation using a Drosophila model. Flies were crossed using the GAL4-UAS system to display Alzheimer's disease …
Two Genetic Effects At The Irf5/ Tnpo3 Locus Are Independently Associated With The Development Of Specific Lupus Symptoms, Samantha Hawtrey
Two Genetic Effects At The Irf5/ Tnpo3 Locus Are Independently Associated With The Development Of Specific Lupus Symptoms, Samantha Hawtrey
Mahurin Honors College Capstone Experience/Thesis Projects
Systemic Lupus Erythematosus (SLE) is an autoimmune disorder that can affect every tissue in the body. Single nucleotide polymorphisms (SNPs) in the IRF5 and TNPO3 genes are statistically associated with the development of SLE. My research identified correlations between IRF5/TNPO3 SNPs and specific lupus symptoms. Logistic regression analyses were conducted using 101 genetic variants in the IRF5/TNPO3 region that were genotyped in over 6,000 lupus patients of different ethnicities, with admixture covariates applied. Three clinical phenotypes displayed significant correlation (p < 1.6x10-5) in subjects of European ancestry. For each of these phenotypes, a step-wise conditional analysis was conducted using two lupus associated single nucleotide polymorphisms (SNPs) at this genetic loci. In Europeans, lupus disease onset (p-valueEU=2.44x10-16, OR=0.67*) and the presence of anti-Ro (p-valueEU=2.09x10-7, OR=0.67) and anti-dsDNA (p-valueEU=4.15x10-7, OR=0.75) antibodies were associated with SNPs in the IRF5/TNPO3 genes. SNPs in the IRF5 promoter and those spanning IRF5 and TNPO3 were both associated with disease onset. The presence of anti-Ro and anti-dsDNA antibodies is only associated with SNPs in the IRF5 promoter. Genetic variants at the IRF5/TNPO3 locus are associated with lupus disease onset and production of anti-dsDNA and anti-Ro antibodies in lupus patients. SNPs in the promoter region of iii IRF5 (associated with rs4728142) and SNPs spanning the IRF5 and TNPO3 genes (associated with rs12534421) contribute independently to these symptoms.

Feelings Of Connectedness To Nature: A Comparison Of Park & Recreation Management Students And Sport Management Students., N. E. Scarborough
Undergraduate Honors Theses
In the face of the present consumer-based environmental movement, leaders in many industries and disciplines are striving to understand why people are “going green” in order to market to them. Researchers have been studying ways in which people connect to the environmental movement, and researchers in the field of sport and recreation are also conducting such studies. Several surveys have been developed to measure these connections; one such survey instrument is the Connectedness to Nature Scale (CNS). In the present study, the CNS was re-created online, and a link to the survey was sent via email to students studying Park …
Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca
Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca
Master's Theses
This thesis focuses on the case study of Senegal to examine the implications of large- scale land acquisitions on the livelihoods of small-scale farmers. I investigate the diverse perspectives of market enthusiasts, human rights organizations, peasants, the state, and international financial organizations on large-scale land acquisitions. Based on primary research, I argue that the state of Senegal plays an active role in permitting “land grabs” and that they pose a threat to food sovereignty among Senegalese host communities. Lastly, I argue there needs to be a broader understanding of long-term consequences and risks to insure social justice in areas affected …

Epidemiologic evidence shows that the risk of ovarian cancer is decreased following childbirth. We examined the time points when the decreased risk of postpartum maternal ovarian cancer reaches the lowest point and whether the protective effect diminishes over time. A case-control study nested within the Swedish Fertility Register included 10,086 cases of epithelial ovarian cancer recorded in the Swedish Cancer Register from 1961 to 2001. From the Fertility Register, 49,249 eligible subjects matched to the cases by age were selected as controls. The analysis contrasted risk between adjacent parities through logistic regression models that included indicator variables representing each year …

Genetic Sex Conditions And Redefining Sex, Jayce O'Shields
Student Scholarship
Western culture has a tendency to value binaries and discreet categories that separate its social structure and provide a sense of order and organization. The value placed on binaries and categories may be advantageous in some aspects, but when it starts to infringe upon the legal and medical rights of individuals not easily placed in either binary category, it can become less advantageous.
A baby is usually classified as either male or female shortly after birth, and all future legal, social, and economic actions and rights of that individual are more or less decided according to this classification. A problem …

Attributing Meaning To Online Social Network Analysis For Tailored Socio-Behavioral Support Systems, Sahiti Myneni
Dissertations & Theses (Open Access)
Ubiquitous online social networks provide us with a unique opportunity to deliver scalable interventions for the support of lifestyle modifications in order to change behaviors that predispose toward cancer and other diseases. At the same time these networks act as rich data sources to inform our understanding of end-user needs. Traditionally, social network analysis is based on communication frequency among members. In this work, I introduce communication content as a complementary frame for studying these networks.
QuitNet, an online social network developed to provide smoking cessation support is considered for analysis. Qualitative coding, automated content analysis, and network analysis were …

When someone puts a piece of food in front of me, I don’t just see a piece of food.
Instead, I see an innocent cow being cornered by a forklift and slaughtered, its limp, moist tissue hung on a long conveyer belt with hundreds of others.
I see hundreds of chemically-injected chickens packed into a dark barn with no hope of seeing sunlight in their lifetime.

Metabolic Remodeling And Mitochondrial Dysfunction In Maladaptive Right Ventricular Hypertrophy Secondary To Pulmonary Arterial Hypertension, Jose Gomez-Arroyo
Metabolic Remodeling And Mitochondrial Dysfunction In Maladaptive Right Ventricular Hypertrophy Secondary To Pulmonary Arterial Hypertension, Jose Gomez-Arroyo
Theses and Dissertations
Right ventricular dysfunction is the most frequent cause of death in patients with pulmonary arterial hypertension. Although abnormal energy substrate use has been implicated in the development of chronic left heart failure, data describing such metabolic remodeling in failing right ventricular tissue remain incomplete. In the present dissertation we sought to characterize metabolic gene expression changes and mitochondrial dysfunction in functional and dysfunctional RV hypertrophy. Two different rat models of RV hypertrophy were studied. The model of right ventricular failure (SU5416/hypoxia) exhibited a significantly decreased gene expression of peroxisome proliferator-activated receptor- coactivator-1α, peroxisome proliferator- activated receptor-α and estrogen-related receptor-α. The …

Longevity And Mortality Of Owned Dogs In England, D. G. O'Neill, D. B. Church, P. D. Mcgreevy, P. C. Thomson, D. C. Brodbelt
Epidemiology Collection
Improved understanding of longevity represents a significant welfare opportunity for the domestic dog, given its unparalleled morphological diversity. Epidemiological research using electronic patient records (EPRs) collected from primary veterinary practices overcomes many inherent limitations of referral clinic, owner questionnaire and pet insurance data. Clinical health data from 102,609 owned dogs attending first opinion veterinary practices (n = 86) in central and southeast England were analysed, focusing on 5095 confirmed deaths.
Of deceased dogs with information available, 3961 (77.9%) were purebred, 2386 (47.0%) were female, 2528 (49.8%) were neutered and 1105 (21.7%) were insured. The overall median longevity was 12.0 years …

Both hepatitis B virus (HBV) and aflatoxin B1 (AFB1) exposure can cause liver damage as well as increase the probability of hepatocellular carcinoma (HCC). To investigate the underlying genetic changes that may influence development of HCC associated with HBV infection and AFB1 exposure, HCC patients were subdivided into 4 groups depending upon HBV and AFB1 exposure status: (HBV(+)/AFB1(+), HBV(+)/AFB1(-), HBV(-)/AFB1(+), HBV(-)/AFB1(-)). Genetic abnormalities and protein expression profiles were analyzed by array-based comparative genomic hybridization and isobaric tagging for quantitation. A total of 573 chromosomal aberrations (CNAs) including 184 increased and 389 decreased were detected in our study population. Twenty-five recurrently …

Smokeless Tobacco Use: A Risk Factor For Hyperhomocysteinemia In A Pakistani Population, Mohammad Perwaiz Iqbal, Mohsin Yakub
Smokeless Tobacco Use: A Risk Factor For Hyperhomocysteinemia In A Pakistani Population, Mohammad Perwaiz Iqbal, Mohsin Yakub
Department of Biological & Biomedical Sciences
Background
Smokeless tobacco (ST) use is highly prevalent in the South Asian populations. While there have been a number of reports on association of ST consumption with cancer, very few studies have been conducted to investigate its relationship with cardiovascular disease. Hyperhomocysteinemia is a well-recognized risk factor for cardiovascular disease; however, its association with ST use has never been investigated. The objective of this study was to evaluate the relationship of ST use with hyperhomocysteinemia in an urban Pakistani population.
Methodology/Principal Findings
In a cross-sectional study for assessment of risks of hyperhomocysteinemia, 872 healthy adults (355 males and 517 females …
