Promoting Occupation For Food Growers With Three Dimensional Printing, Robin Gibbs, Mary Thelander-Hill

Occupational Therapy

Assistive technology and three-dimensional (3D) printing offer opportunities for occupational therapy practitioners to promote occupational engagement for food-growers. 3D printing began more than 40 years ago with a goal of creating a solid object from a digital model. Recently, this technology has become more accessible due to the low-cost of personal-use printers and easy-to-use programs for designing 3D models. With this technology it is now possible for occupational therapists to design, individualize, and print assistive technology to provide benefit and promote engagement for food growers.

Constantino Escalante's Lithographs In La Orquesta And The National Legacy Of The Mexican Constitution Of 1857, Steven Vaughn Cary

Art & Art History ETDs

An examination of the lithographic prints of Constantino Escalante in the Mexican publication, La Orquesta, was undertaken for the years 1861 through 1868. Foremost among La Orquesta’s concerns and repeatedly appearing in Escalante’s work, is the importance of the Constitution of 1857 as the Liberal instrument for Mexico’s journey to become a sovereign, modern state. During a tumultuous period of 19^th century Mexican history, Escalante and La Orquesta dealt with sustained threats and censorship, causing frequent and intermittent shutdowns. An early supporter of Benito Juárez, La Orquesta radically amended its positive view of Juárez following the unsuccessful attempts …

Integrated Grating Couplers On-A-Chip: Characterizations And Applications, Xuemei Wang

Optical Science and Engineering ETDs

We demonstrate two applications based on grating coupled phase matching to a slab waveguide: lab-on-a-chip spectrometer using a transversely chirped grating and indoor lidar plenoptic sensor array for Time of flight (ToF) position mapping system.

Development Of A Measure Of Physical Distancing: The O'Sickey Distancing Test, Anthony J. O'Sickey

Psychology ETDs

Introduction: Covid-19 has swept the globe and has disproportionately affected the United States with over 600,000 deaths in just over one year. The Centers for Disease Control recommendations for reducing the spread of Covid-19 have focused on physical distancing (PD), the practice of maintaining a distance greater than 6 feet from individuals not in the same household. When employed, this health behavior has been found to reduce the incidence of Covid-19. A review of the measurement literature evaluating PD indicates that PD has been measured at the community level via GPS, using proxy measures of the behavior, or as a …

Control Mechanisms For Adaptive Nanoscale Devices, David Arredondo

Nanoscience and Microsystems ETDs

Nanotechnology promises to revolutionize many areas of applied science including materials, synthetic biology, and medicine. Devices may consist of solution-phase information processing systems or molecular robots. Of particular interest are DNA-based systems due to their composability and relatively simple interactions that are suited to bottom-up design. This work introduces high-level designs of robust control mechanisms for nanoscale devices with immediate applications in molecular computing, synthetic biology, and DNA robotics.

Nanoscale systems are dominated by probabilistic chemical behavior, so engineers must take careful consideration to produce predictable systems. Probabilistic behavior in chemical reaction networks (CRNs) yields deterministic evolution of species concentrations …

The Warrior To Scholar Identity Transformation, Eliberto Trevizo Calderon

Organization, Information and Learning Sciences ETDs

ABSTRACT

This qualitative emergent study investigated the identity transformation experiences of enlisted combat student veterans (ECSVs) from warriors into scholars at the University of New Mexico (UNM). ECSVs are a sub-population of the student veteran community who served in military combat jobs and thus underwent a military indoctrination process that inculcated a warrior identity in them. When ECSVs bring the warrior identity with them to campus, it may conflict with the scholar identity, causing them to struggle to assimilate into the university environment. The study used semi-structured individual interviews and a focus group for data collection and open, thematic, and …

Alterations In Executive Functioning Following Moderate Prenatal Alcohol Exposure: New Translational Insights, Sarah L. Olguin

Biomedical Sciences ETDs

While the lifelong difficulties that result from alcohol exposure in utero are well documented, Fetal Alcohol Spectrum Disorders (FASD) remain the most common neurodevelopmental syndrome. FASD patients struggle with executive control including attention, cognitive control, reward learning, and impulsivity. These self-regulation problems contribute to increased rates of school expulsion, incarceration, and substance use disorders. However, it is still unclear how prenatal alcohol exposure (PAE) affects executive control processes that lead to inappropriate behavior later in life. Here we examined the effect of PAE on 4 aspects of executive functioning paired with intervention or with translatable EEG-like recording, 1) control over …

Run-To-Run Control Via Constrained Optimization Of A Mechanical Serial-Sectioning System, Damian L. Gallegos-Patterson

Mechanical Engineering ETDs

This thesis develops a methodology for run-to-run (R2R) control of a mechanical serial sectioning (mss) system for microstructural investigations. mss is a destructive material characterization process which repeatedly removes a thin layer of material and images the exposed surface. The images are then used to gain insight into the internal structure and arrangement of a material and are often used to generate a 3-dimensional (3D) reconstruction of the sample. Currently, an experienced human operator selects the parameters for mss to achieve the desired per slice removal rate. The proposed R2R control methodology automates this process while improving the precision and …

Atomic Gradiometry Based On The Interference Of Microwave Optical Sidebands, Kaleb L. Campbell

Optical Science and Engineering ETDs

We describe a novel pulsed magnetic gradiometer based on the optical interference of sidebands generated using two spatially separated alkali vapor cells. The sidebands are produced with high efficiency using parametric frequency conversion of a probe beam interacting with Rubiduim 87 atoms in a coherent superposition of magnetically sensitive hyperfine ground states. First, experimental evidence of the sideband process is described for both steady-state and pulsed operation. Then, a theoretical framework is developed that accurately models sideband generation based on density matrix formalism. The gradiometer is then constructed using two spatially separated vapor cells, and a beat-note is generated. The …

High-Resolution Fiber Imaging For Pulsed Power Experiments, Karin Wikander Fulford

Electrical and Computer Engineering ETDs

This thesis project explores the use of high-resolution plastic optical fibers for imaging emission from low-density plasmas in pulsed power experiments. These plasmas may be responsible for driving current loss and modifying the instability structure in magneto inertial fusion approaches such as Magnetized Liner Inertial Fusion (MagLIF); however, imaging their dynamics on the Z machine is an on-going effort. Addressing this, a compact and adaptable imaging system was developed to capture visible self-emission events in these extreme environments. Initiated as a tool for the Z machine, the project was named fiber imaging on Z (FIZ). The FIZ design utilizes a …

Exploring Components For A Family-Focused Intervention For Families With A Child Diagnosed With Cancer And Other Chronic Illnesses, Nicole Kubinec

Psychology ETDs

Chronic illnesses are often life-long and affect academic performance, social development, psychological well-being, and family functioning. The broad effects of childhood chronic illnesses are often assessed using measures of child health-related quality of life (HRQL). Parent factors (parental distress, perceptions of child vulnerability, overprotection) and family factors (maintaining rituals, open communication, positive coping) have been associated with changes in child HRQL. This study sought to discover how parent and family factors were associated with child HRQL, and how such factors were perceived by families for inclusion in future interventions. Results demonstrated that parental perceptions of child vulnerability were associated with …

Neuroanatomical And Environmental Correlates Of Psychopathy Subtypes In Incarcerated Youth And Implications For Recidivism, Devin Marie Ulrich

Psychology ETDs

Researchers have described subtypes of psychopathy including a primary “constitutional” variant influenced largely by biological factors, and a secondary variant “acquired” through environmental factors (e.g., trauma) and associated with elevated internalizing symptoms. This study used latent profile analysis (LPA) in a sample of 297 juvenile male offenders to identify subgroups of incarcerated youth, based on level of psychopathic traits and anxiety, as measured by the Psychopathy Checklist: Youth Version (PCL:YV) and Multidimensional Anxiety Scale for Children (MASC), respectively, and explore environmental and neural correlates of resulting groups. Two groups were identified that differed in psychopathic trait level, experience of trauma, …

Computational, Synthetic And Spectroscopic Studies On Donor Acceptor Transition Metal Complexes, Ranjana Dangi

Chemistry and Chemical Biology ETDs

Fundamental advances in our ability to design and construct electronic components at the nanoscale will require new design paradigms. One proposed nanoscale electronic component is the molecular rectifier. Molecular and molecule-based electronic components are advantageous due to their ease of synthetic manipulation, and the fact that the size dimensions of molecules are inherently at the nanoscale (0.5 - 3nm). Our group has shown how the Donor-Bridge-Acceptor biradical approach can be used to derive key structure-property relationships that allow insight into the choice of bridge fragments for molecular rectification by using constitutional isomers of the donor-bridge-acceptor biradical (NN-Th-Py-SQ) (S=1/2 ortho-semiquinonate, …

Olfactory Detection Of Viruses Shapes Brain Immunity And Behavior, Aurora Kraus

Biology ETDs

Olfactory sensory neurons (OSNs) directly contact the environment and are

exposed to pathogens, such as viruses. When OSNs detect a virus, they coordinate antiviral immune responses locally to stop virus progression into the brain, termed the central nervous system (CNS). For example, in COVID-19 patients the SARS-CoV-2 virus replicates in the olfactory epithelium resulting in loss of olfaction, yet viral presence in the CNS is rare. However, neuronal detection of a virus by OSNs may send electrical signals to the CNS via the olfactory bulb (OB) and shape our CNS. Because the OB is the nexus between the pathogen exposed …

A Theory Of Text Setting Contour: A Proposed Theory That Places Text At The Structural Foreground Of The Analysis Of Vocal Music, Grace K. Weaver

Music ETDs

How can contour theory be used to analyze a composer’s setting of a poem? Can this approach provide insights that lead to an interpretation of the composer’s setting of the text? This study presents a new contour theory on text setting by examining two different settings of the same text. This theory examines one aspect of the music, the vocal line, and plots syllable’s locations in two dimensions of music: pitch space and duration. Using these data points, one can suggest an interpretation of the poem. Through the application of this theory to Fanny Hensel and Franz Schubert’s setting of …
