Zapatista Maya Literacies And Decolonial Civic Pedagogies, Juan Moisés García-Rentería

Open Access Theses & Dissertations

Zapatista Maya Literacies and Decolonial Civic Pedagogies evaluates an educational outreach project led by an Indigenous grass roots mobilization in the high plateau of central México, the Zapatista movement. Using retrospective narrative inquiry and theoretically informed perspectives, this dissertation shows that the program of the Zapatista escuelita, Spanish for “little school,” is rooted in the Maya educational paradigm of nojptesel-p’ijubtasel, a cultural and political process of socialization at the heart of contemporary Maya peasant families. The research focus of this study offers rhetoric, composition, and literacy studies two interrelated points of insight tied to the overall Maya conception of the …

Hannah Arendt And The Recreation Of The Public Space At The El Paso-Ciudad Juarez Border, Maximiliano Gutierrez

Open Access Theses & Dissertations

Arendt's philosophy is essentially phenomenological, especially her concept of the world of appearances in which everything manifests itself to human begins with those who share this space. Her phenomenological approach to philosophy enables us to shed light on the realm of public affairs, namely, being born, plurality, and specifically I argue, immigration. In this case I am referring to immigration in its most general meaning, that is, to the act of moving into another country and, thereby, leaving one's own private space in their former country. In order to best understand this phenomenological approach, it is necessary to understand Arendt's …

Development Of An Automated Electronic Prototyping System, Cesar Yahir Sanchez Zambrano

Open Access Theses & Dissertations

Prototyping systems with interconnected components can be a time and resource expensive process. The process consists of three main phases (design, build and analysis) with each having their own associated cost. For the case of electronic circuits, the building phase is the costliest phase among the three, being prone to human errors which causes the circuit to fail. All three phases of the prototyping process are important. However, often a disproportionate amount of time is spent on the build phase due to the difficulty of making and troubleshooting circuits by hand. In this thesis we will discuss a system that …

Gender Perceptions And Female Students' Academic Engagement And Success In Stem Fields, Rheanna Morgan

School of Social Work Undergraduate Honors Theses

Despite an increase of females in higher education and the workforce, fields such as science, technology, engineering, and mathematics (STEM) continue to be male-dominated. One explanation for this trend is the lack of gender representation and counterstereotypical role models to encourage female engagement in these fields at the university level. Previous research has looked at instructor gender, classroom gender composition, and involvement in extracurricular activities as possible factors influencing students' engagement and success in the classroom. However, few studies have investigated how gender perceptions influence female students in STEM fields. This study uses self-report data from a voluntary survey to …

Seasonal Variability Of Phytoplankton Population Dynamics In Coastal New Hampshire, Molly Erickson

Master's Theses and Capstones

Phytoplankton population dynamics are significant indicators of ecosystem health and marine food web structure. Phytoplankton population dynamics are also highly variable, especially within complex coastal ocean systems. To capture temporal phytoplankton population dynamics, a weekly time series measuring temperature, salinity, tide height, chlorophyll a concentration, nutrients, and phytoplankton biodiversity was performed at two sites in New Hampshire over an annual cycle. Despite being geographically close in proximity, the coastal and estuarine locations were very different in terms of blooming periods, community composition, and ecological factors. Phytoplankton blooms occurred at least once each season on the coast, consisting of Rhizosolenia sp., …

Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine

Graduate Theses and Dissertations

Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …

The Latin American Tragedy: A Qualitative Research Of How Culture, Media, And Gender Roles Lead To Femicide, Vanessa Gonzalez

Honors College Theses

This study aims to analyze how Latin American cultural values and popular media perpetuate harmful gender stereotypes that can subsequently contribute to the growing femicide rates happening across the region. Although violence against women is a global issue, Latin American femicide is characterized by cultural, systemic, and political factors that not only allow it to thrive but make it unique in a global context as it relates to the discussion around violence against women. Adherence to honor culture, gender-based stereotypes like that of machismo and marianismo, along with the overt sexualization of Latin women in popular media, create a domino …

Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition: A Brief Exploration And Application Of Extension Principles, Micah Samuel Most

Department of Animal Science: Dissertations, Theses, and Student Research

The objective of our first study was to determine how administering anti-inflammatory dexamethasone and ω-3 polyunsaturated fatty acid (PUFA)-rich fish oil affects growth efficiency and body composition in heat-stressed finishing lambs. Commercial wethers were randomly assigned to be fed under heat stress (35-40 ℃) or thermoneutral (19 ℃, n = 10) conditions for 30 d, and controls were pair-fed to eliminate differential feed intake. Heat-stressed wethers were randomly assigned to receive clinical-dose dexamethasone IM injections every 72 h, twice daily fish oil capsule oral boluses, or placebos. Heat stress decreased (P < 0.05) growth and efficiency, but dexamethasone and fish oil supplementation recovered these performance measures. Heat stress also decreased (P < 0.05) predictive body composition metrics that were at least partially improved by administration of dexamethasone and fish oil. Proximate analyses of muscles showed that heat stress decreased (P < 0.05) percentage of protein and increased (P < 0.05) percentage of intramuscular fat, neither of which was improved by dexamethasone or fish oil. Immunohistochemistry revealed that heat stress decreased (P < 0.05) myoblast differentiation and muscle fiber size, but anti-inflammatory supplementation recovered differentiation only. Plasma IGF-1 concentrations were not different among groups throughout the study. These findings demonstrate how heat stress-induced inflammation contributes to impaired growth, efficiency, and body composition observed in heat-stressed feeder lambs. However, targeting inflammation with dexamethasone or fish oil recovers many of these deficits.
