Experiences And Perceptions Of Human Vulnerability To Climate Change In Calakmul, Mexico, Lisa Green Aug 2017

Experiences And Perceptions Of Human Vulnerability To Climate Change In Calakmul, Mexico, Lisa Green

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report explores how residents of Calakmul, Mexico perceive and experience their own vulnerability to climate change, and how these perceptions and experiences are differentiated among communities, households, and individuals. Fifty-five semi-structured interviews in 2013 and 45 follow-up interviews in 2016 provide data on familiarity with climate change and perceived effects of climate-related stressors on livelihood activities, health, and experiences of hunger. We found that coping responses to the effects of climate change often require cash inputs, and communities are differentiated in their experiences of vulnerability, based in part on their access to wage labor and importantly governmental support.

BACKGROUND: Antimicrobial Stewardship Programs (ASPs) have been promoted to optimize antimicrobial usage and patient outcomes, and to reduce the emergence of antimicrobial-resistant organisms. However, the best strategies for an ASP are not definitively established and are likely to vary based on local culture, policy, and routine clinical practice, and probably limited resources in middle-income countries. The aim of this study is to evaluate structures and resources of antimicrobial stewardship teams (ASTs) in surgical departments from different regions of the world. METHODS: A cross-sectional web-based survey was conducted in 2016 on 173 physicians who participated in the AGORA (Antimicrobials: A Global …

Personality Traits As Predictors Of Pair-Housing Compatibility In Garnett's Greater Bushbabies (Otolemur Garnettii), Karen A. Schaffer Aug 2017

Personality Traits As Predictors Of Pair-Housing Compatibility In Garnett's Greater Bushbabies (Otolemur Garnettii), Karen A. Schaffer

Honors Theses

Continuously refining husbandry strategies to improve the welfare of captive primates is a research priority. A variety of enrichment strategies are employed to allow captive primates opportunities to exercise natural behaviors with the aim of maintaining their psychological health in environments different from those for which they evolved. Arguably the most important of these strategies is social housing, since primates are by definition social animals. Pair housing is often the most logistically feasible method; however, the process of introducing partners to each other comes with risks of stressful conflict that may result in injury, and the necessarily trial-and-error nature of …

Angular Distribution Of Single-Photon Superradiance In A Dilute And Cold Atomic Ensemble, A. S. Kuraptsev, I. M. Sokolov, M. D. Havey

Physics Faculty Publications

On the basis of a quantum microscopic approach we study the dynamics of the afterglow of a dilute Gaussian atomic ensemble excited by pulsed radiation. Taking into account the vector nature of the electromagnetic field we analyze in detail the angular and polarization distribution of single-photon superradiance of such an ensemble. The dependence of the angular distribution of superradiance on the length of the pulse and its carrier frequency as well as on the size and the shape of the atomic clouds is studied. We show that there is substantial dependence of the superradiant emission on the polarization and the …

An Examination Of The Relationships Between Social Anxiety Dimensions And Alcohol-Related Outcomes: The Mediating Role Of Drinking Context, Margo Cooley Villarosa Aug 2017

An Examination Of The Relationships Between Social Anxiety Dimensions And Alcohol-Related Outcomes: The Mediating Role Of Drinking Context, Margo Cooley Villarosa

Dissertations

The problematic drinking patterns of the college student population has elicited a campus-wide initiative to promote effective prevention and intervention efforts to reduce the range of associated academic, physical, and psychosocial consequences. Identifying those college students at greater risk for developing an alcohol use disorder informs student life personnel of ways to tailor efforts to ensure effective, healthy changes. Students with social anxiety pose a particular risk for developing problematic drinking patterns because of their heightened focus on how they are viewed by others in social situations coupled with drinking being viewed as a normative behavior. Because these students’ anxiety …

Synthesis And Catalytic Evaluation Of Novel C-Alpha-Methyl-Beta-Proline Analogues, And Concise Synthetic Approach To Nh-Fmoc-S-Trityl-C-Alpha-Methyl Cysteine, Hari Kiran Kotapati

Dissertations

In the field of chemistry there is a growing demand for small molecule organocatalysts such as amino acids, more specifically proline and its analogues, which could catalyze various key chemical reactions in the synthesis of several biologically important molecules. Even though natural proline is reported to catalyze various chemical reactions, its use as organocatalyst is limited mainly due to the solubility issues in the reaction media and high catalyst loadings, which is not very ideal for bulk scale manufacturing. To address these limitations we planned to develop unnatural analogues of proline that could catalyze the reactions with lower catalyst loadings …

Validation Of The Young Adult Relational Aggression Scale, Caitlin M. Clark Aug 2017

Validation Of The Young Adult Relational Aggression Scale, Caitlin M. Clark

Dissertations

Relational aggression has been associated with a host of negative correlates in previous studies of children, adolescents, and emerging adults. Further research is necessary for the purposes of identifying prevention and intervention strategies; however, research on relational aggression among emerging adults has been complicated by the lack of available psychometrically sound measures, particularly those that capture the proactive and reactive functions of relational aggression. The present study extended previous efforts to develop a new self-report measure of relational aggression for emerging adults called the Young Adult Relational Aggression Scale (YARAS). A confirmatory factor analysis (CFA) was performed using a sample …

Solution Of Pdes For First-Order Photobleaching Kinetics Using Krylov Subspace Spectral Methods, Somayyeh Sheikholeslami Aug 2017

Solution Of Pdes For First-Order Photobleaching Kinetics Using Krylov Subspace Spectral Methods, Somayyeh Sheikholeslami

Dissertations

We solve the first order reaction-diffusion equations which describe binding-diffusion kinetics using a photobleaching scanning profile of a confocal laser scanning microscope approximated by a Gaussian laser profile. We show how to solve these equations with prebleach steady-state initial conditions using a time-domain method known as a Krylov Subspace Spectral (KSS) method. KSS methods are explicit methods for solving time- dependent variable-coefficient partial differential equations (PDEs). KSS methods are advantageous compared to other methods because of their stability and their superior scalability. These advantages are obtained by applying Gaussian quadrature rules in the spectral domain developed by Golub and Meurant. …

Coenzyme A (CoA) and acetyl-coenzyme A (acetyl-CoA) play essential roles in cell energy metabolism. Dysregulation of the biosynthesis and functioning of both compounds may contribute to various pathological conditions. We describe here a simple and sensitive HPLC-UV based method for simultaneous determination of CoA and acetyl-CoA in a variety of biological samples, including cells in culture, mouse cortex, and rat plasma, liver, kidney, and brain tissues. The limits of detection for CoA and acetyl-CoA are >10-fold lower than those obtained by previously described HPLC procedures, with coefficients of variation

Department of Paediatrics and Child Health

Children in low- and middle-income countries are at high risk of cognitive deficits due to environmental deprivation that compromises brain development. Despite the high prevalence of unrealized cognitive potential, very little is known about neural correlates of cognition in this population. We assessed resting EEG power and cognitive ability in 105 highly disadvantaged 48-month-old children in rural Pakistan. An increase in EEG power in gamma frequency bands (21-30Hz and 31-45Hz) was associated with better executive function. For girls, EEG gamma power also related to higher verbal IQ. This study identifies EEG gamma power as a neural marker of cognitive function …

Elongation Factor P Interactions With The Ribosome Are Independent Of Pausing, Rodney Tollerson Ii, Anne Witzky, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacterial elongation factor P (EF-P) plays a pivotal role in the translation of polyproline motifs. To stimulate peptide bond formation, EF-P must enter the ribosome via an empty E-site. Using fluorescence-based single-molecule tracking, Mohapatra et al. (S. Mohapatra, H. Choi, X. Ge, S. Sanyal, and J. C. Weisshaar, mBio 8:e00300-17, 2017, https://doi.org/10.1128/mBio.00300-17 ) monitored the cellular distribution of EF-P and quantified the frequency of association between EF-P and the ribosome under various conditions. Findings from the study showed that EF-P has a localization pattern that is strikingly similar to that of ribosomes. Intriguingly, EF-P was seen to bind ribosomes more …

Adipocytes secrete the hormone leptin to signal the sufficiency of energy stores. Reductions in circulating leptin concentrations reflect a negative energy balance, which augments sympathetic nervous system (SNS) activation in response to metabolically demanding emergencies. This process ensures adequate glucose mobilization despite low energy stores. We report that leptin receptor–expressing neurons (LepRb neurons) in the periaqueductal gray (PAG), the largest population of LepRb neurons in the brain stem, mediate this process. Application of noxious stimuli, which often signal the need to mobilize glucose to support an appropriate response, activated PAG LepRb neurons, which project to and activate parabrachial nucleus (PBN) …

Ventricular Action Potential Adaptation To Regular Exercise: Role Of Β-Adrenergic And KAtp Channel Function, Xinrui Wang, Robert H. Fitts

Biological Sciences Faculty Research and Publications

Regular exercise training is known to affect the action potential duration (APD) and improve heart function, but involvement of β-adrenergic receptor (β-AR) subtypes and/or the ATP-sensitive K+ (KATP) channel is unknown. To address this, female and male Sprague-Dawley rats were randomly assigned to voluntary wheel-running or control groups; they were anesthetized after 6–8 wk of training, and myocytes were isolated. Exercise training significantly increased APD of apex and base myocytes at 1 Hz and decreased APD at 10 Hz. Ca2+ transient durations reflected the changes in APD, while Ca2+ transient amplitudes were unaffected by wheel …

A Church Based Curriculum Providing Marriage And Family Education For Stepfamilies And Ministries, Richard Helein Aug 2017

A Church Based Curriculum Providing Marriage And Family Education For Stepfamilies And Ministries, Richard Helein

Doctoral Dissertations and Projects

Within the American population, the Stepfamily now outnumbers that of the traditional nuclear family; a trend mirrored in the local church. Stepfamilies within the church culture struggle in navigating the relational complexities, emotional and spiritual strain, and biblical confusion inherent to the formation of a stepfamily, while church leaders lack both understanding and the training necessary to minister to this growing population. Often step-families choose anonymity or leave the local church for fear of being shunned. In synthesizing, existing research with data garnered from stepfamilies via their participation in an anonymous online survey and participatory learning activity (PLA), challenges unique …
