The Labour Of Austerity: Absurdity, Performative Resistance, And Cultural Transformation, Nora Almeida

Publications and Research

This essay explores the social-psychic toll of prolonged austerity on academic librarians and the range of strategies that have (or could) serve as tools of resistance. Using a combination of theoretical analysis and autoethnography, I examine the emotional impact of bottomless and invisible labour imposed by austerity and the ways institutions use emotional coercion to promote self-surveillance, meta-work, and hyper-productivity. Following this analysis, I discuss the ways that oppressive institutional cultures silence dissent and absorb common resistance tactics advocated by educators. Finally, I introduce several examples of performance-based resistance projects and explore how creative, personal, and absurd forms of protest …

Rpas: An Enhanced Finite Element Code For The Mechanistic Analysis Of Rigid Pavements, Nancy Aguirre

Open Access Theses & Dissertations

Significant amount of research has been conducted to improve the design of rigid pavements through the development of mechanistic analysis tools capable of accurately modeling the performance of such pavements. The use of the finite element (FE) method as a comprehensive tool for modeling the responses of rigid pavements has been limited in the past because of the complexity of calculations in modeling nonlinear behaviors, which are difficult to describe mathematically and computationally. Researchers from The University of Texas at El Paso developed NYSLAB, an FE modeling tool, for the analysis of rigid pavements subjected to traffic and environmental loading …

Fabrication, Development, And Characterization Of Hipco Swcnt - Alginate Hydrogel Composites For Cellular Product Applications, Fabian Armando Alvarez-Primo

Open Access Theses & Dissertations

In this study, we designed, synthesized, and characterized ultrahigh purity single-walled carbon nanotube (SWCNT)-alginate hydrogel composites. Among the parameters of importance in the formation of an alginate-based hydrogel composite with single-walled carbon nanotubes, are their varying degrees of purity, their particulate agglomeration and their dose-dependent correlation to cell viability, all of which have an impact on the resultant compositeâ??s efficiency and effectiveness towards biomedical applications. To promote their homogenous dispersion by preventing agglomeration of the SWCNT, at first, we used three different surfactants-sodium dodecyl sulfate (SDS-anionic), cetyltrimethylammonium bromide (CTAB-cationic), and Pluronic F108 (nonionic). After experimentation and corroboration through evidence obtained …

Assessment Of Hydraulic And Structural Behavior Of Inundated Pavements, Mojtaba Asadi

Open Access Theses & Dissertations

Severe flooding events have increasingly inundated the transportation infrastructure, including road networks, across the world and the Unites States. Such extreme events induce significant ingress of water into the pavement layers, which in turn leads to structural defects due to the reduction of the shear strength and resilient moduli of the soil layers, asphalt stripping in flexible pavements, pumping effect in rigid pavements, migration of fines into drainable layers, and swelling of expansive soils. Consequently, premature pavement failure may take place that can impose unforeseen maintenance/rehabilitation costs to highway agencies. Although some experimental research studies have been conducted to assess …

Abstraction Techniques In Security Games With Underlying Network Structure, Anjon Basak

Open Access Theses & Dissertations

In a multi-agent system, multiple intelligent agents interact with each other in an environment to achieve their objectives. They can do this because they know which actions are available to them and which actions they prefer to take in a particular situation. The job of game theory is to analyze the interactions of the intelligent agents by different solution techniques and provide analysis such as predicting outcomes or recommending courses of action to specific players. To do so game theory works with a model of real-world scenarios which helps us to make a better decision in our already complex daily …

Structure-Property-Performance Evaluation Of Refractory Metal Incorporated Gallium Oxide Thin Films For Extreme Environment Applications, Anil Krishna Battu

Open Access Theses & Dissertations

An approach is presented to design refractory-metal (RM) incorporated Ga2O3-based materials with controlled structural, mechanical, and optical properties. A model system based on molybdenum (Mo) doped Ga2O3 (GMO) has been considered to elucidate the combined effect of RM-doping and processing parameters on the properties and oxygen sensor performance of GWO nanomaterials. The molybdenum (Mo) content in Ga2O3 was varied from 0 to 11 at% in the sputter-deposited Ga-Mo-O films. Molybdenum was found to significantly affect the structure and optical properties. While low Mo content (≤4 at%) results in the formation of single-phase (β-Ga2O3), higher Mo content results in amorphization. Chemically …

Association Of A Repetitive Manual Task On Inflammatory Biomarker Expression, Heart Rate Variability And Rating Of Perceived Exertion, Daniel Conde

Open Access Theses & Dissertations

The National Institute for Occupational Safety and Health (NIOSH) defines work related musculoskeletal disorders (WMSDs) as a group of disorders involving muscles, tendons, and nerves. The WMSDs symptoms are considered the most common occupational disease, causing limitations in daily activities. Even though there is an association between repetitive manual tasks involving short work cycles, force demanding tasks, and the development of WMSDs, the specific cause of the physiological changes over a long period of time is a cause of debate. The study of mechanisms underlying the physiological changes is essential for the early detection, diagnosis, and appropriate management of WMSDs.

Sensory Integration And Its Role In Behavioral Plasticity In Children Diagnosed With Autism Spectrum Disorder, Clarissa Diaz

Open Access Theses & Dissertations

Although commonly characterized by communicative and social impairments, Autism Spectrum Disorder (ASD) presents a number of developmental deficits related to movement planning and action. The extent of these deficits to the entire neuromuscular system, as well as the individual input/output loops are still not well understood. Given the dynamic interplay between our plans, actions and outcomes lay the foundation for later mature motor behavior, it is critical to understand the unique motor learning processes these nervous systems face while a higher level of training plasticity may be present. A recent study examined the kinematics (acceleration, velocity, smoothness, etc.) of upper …

Structural Analysis Of Deformed Caprock Associated With A Salt Shoulder At Gypsum Valley Salt Wall, Paradox Basin, Colorado, Hanah Draper

Open Access Theses & Dissertations

This study documents the style and distribution of deformation present in Triassic-age gypsic and carbonate caprock associated with the Gypsum Valley Salt Wall Salt Shoulder in the Paradox Basin, Colorado in order to determine the mechanism and timing of deformation. Mapping of gypsic and carbonate capstone facies shows that the caprock layering that was generated during formation has been deformed by large-and-small-scale folding and faulting, brecciation, and boudinage. Deformation within the caprock resulted in widely variable orientations along the length of the salt shoulder, that also varies locally in intensity of deformation and with proximity to the passively rising diapir …

We Are All Green: Stereotypes For Female Soldiers And Veterans, Katherine French

Open Access Theses & Dissertations

As the number of females in the U.S. military continues to rise, the need for research concerning this cohort becomes increasingly important. In consideration of gender role theory, society may assume that soldiers and veterans are male, due to stereotypes. Thus, it was hypothesized that participants would be more likely to implicitly associate military (i.e. prior military or combat veteran) as male compared the neutral condition (i.e. prior Peace Corp volunteer). The current study (N = 174) used gender pronouns as implicit measures of gender assumptions. Participants were assigned to read six gender neutral scenarios; three focal scenarios (i.e. combat …

Extracting Mechanical Properties Of Compacted Geomaterials Using Intelligent Compaction Technology, Aria Fathi

Open Access Theses & Dissertations

The primary tool currently used for quality management of earthwork and unbound aggregates is the nuclear density gauge (NDG) to ensure appropriate density and moisture content. Measurement of moisture content and dry density, even though quite practical and straightforward, does not directly tie the construction quality with the mechanistic-empirical design processes where stress and modulus are employed. With the recent popularity of the mechanistic pavement design procedures, research efforts have been undertaken to understand and develop procedures for implementing modulus-based quality control (QC) procedures of compacted geomaterials. These procedures involve the use of in-situ nondestructive testing (NDT) devices that estimate …

Identification Of A Novel Single Amino Acid Substitution (V666g) Of Jak1 From A Patient With Acute Lymphoblastic Leukemia Impairs Jak3 Mediated Il-2 Signaling, Alice Hernandez Grant

Open Access Theses & Dissertations

The Janus kinase (JAK) family, notably JAK1, JAK2 and JAK3 are recognized as oncogenic drivers in high risk Acute Lymphoblastic Leukemia (ALL). The bulk of activating JAK mutations are thought to occur within functional hot-spots across Janus Homology (JH) domains. The most frequently mutated regions is the JH2 pseudo-kinase, which provides a negative regulatory role to the adjacent catalytically active JH1 kinase domain. Despite the prevalence of JAK activating mutations and a need for new therapeutic inhibitors, there is a lack of understanding in the allosteric regulation of JAK kinases. Here we sought to identify mutations involved in driving ALL …

Comparative Experimental And Theoretical Study Of Dopamine And Serotonin Interaction, Jose A. Guerrero

Open Access Theses & Dissertations

To accurately identify and measure the concentrations of dopamine (DA) and serotonin (5-HT) in mixtures of these neurotransmitters without labeling, a comprehensive, comparative computational and Raman experimental analysis is provided. While the distinction between these two analytes may be accomplished for concentrations in the millimolar range of these mixtures, their accurate quantification remains unattainable. As shown for the first time in this study, potential creation of a new composite resulting from their interactions with each other could be a reason for this lack of quantification.

Although this new hydrogen-bonded complex greatly complicates future analyte differentiation and quantification at concentrations typical …
