Mothers’ Satisfaction With Childcare Choices And Its Links To Family Involvement And Community Support, Hadeel Shamlan Al-Essa

Individual, Family, and Community Education ETDs

This study examined mothers ’reports on types of childcare arrangement for a preschool-age child, levels of mothers’, fathers’, and relatives’ involvement in childcare at home, maternal satisfaction with childcare arrangement, the influence of socioeconomic status and social support on mothers ’satisfaction with childcare arrangement, and the nature of mothers ’affection, responsiveness, encouragement, and teaching behaviors during mother-child play sessions. The sample consisted of 130 New Mexico mothers from two-parent families with a preschool child. A subsample of four mothers was selected for collecting data on mother-child play interactions through a 10-minute observation session. Analyses suggested that mothers were the primary …

The Effects Of Glycosylation On Immunogenicity And Replication Of Emerging Viral Pathogens, Elizabeth Carvosso Clarke

Biomedical Sciences ETDs

For filoviruses, a family of hemorrhagic fever viruses, the main antigen for vaccines in development is the glycosylated glycoprotein GP1,2. How the glycosylation of GP1,2 differs when the protein is produced in different cell lines is unclear. We showed significant differences in the types of glycans conferred onto filovirus GP1,2s in produced in mammalian-origin and insect-origin cell lines. Mammalian-derived filovirus GP1,2s have diverse N-linked glycans and extensive O-linked glycans, whereas insect-derived filovirus GP1,2s have N-linked glycans that are primarily paucimannose type and have no observable O-linked glycans. We then showed that differences in glycosylation impacted how immunogenic the proteins were …

Between The Visceral And The Lie : Lessons On Teaching Violence, Brian Gibbs

Intersections: Critical Issues in Education

Drawing from two qualitative case studies, one researching how teachers teach about war to the children of soldiers and the other examining how teachers teach lynching near historic lynching sites, this critical phenomenological study weighs how much horror and how much hope should be taught if the aim of the instruction is a liberating education. The author argues that a balance of both is necessary. Students cannot be left in the hopelessness of knowledge alone but must be taught how to engage their world with the possibility of making change.

Role Of Β-Glucan Structure In Dectin-1 Homo- And Hetero-Oligomerization In Innate Anti-Fungal Immunity, Eduardo U. Anaya

Biomedical Sciences ETDs

Dectin-1A is a C-type Lectin innate immunoreceptor that recognizes β-(1,3)-glucan, a structural component of Candida species cell walls. Dectin-1 has eight alternative splice isoforms including, A and B. Innate immunocytes can express one or both isoforms, but neither their relative responsiveness to β-glucan nor the potential for inter-isoform signaling cross-talk is well understood. In this study, we determine how the different structures of soluble β-glucans affect both isoforms and unravel how differences in glucan structure impact the earliest events in Dectin-1 signaling. Using quantitative microscopy techniques, we explored the role of glucan structure on Dectin-1A oligomerization, which is thought to …

Hunger, Patrick A. Brown, Kylie M. Getz, Cem Meydan, Christopher E. Mason, Aristotelis Tsirigos, William Carroll

Pathology Research and Scholarship

Although B-cell acute lymphoblastic leukemia (B-ALL) is the most common malignancy in children and while highly curable, it remains a leading cause of cancer-related mortality. The outgrowth of tumor subclones carrying mutations in genes responsible for resistance to therapy has led to a Darwinian model of clonal selection. Previous work has indicated that alterations in the epigenome might contribute to clonal selection, yet the extent to which the chromatin state is altered under the selective pressures of therapy is unknown. To address this, we performed chromatin immunoprecipitation, gene expression analysis, and enhanced reduced representation bisulfite sequencing on a cohort of …

Monte Carlo Simulations Of Awkward Actions, David John Amdahl

Physics & Astronomy ETDs

Time derivatives of scalar fields occur quadratically in textbook actions. A simple Legendre transformation turns the Lagrangian into a Hamiltonian that is quadratic in the momentum. The partition function over the momentum is Gaussian. Mean values of operators are basically euclidian path integrals of their classical counterparts with positive weight functions. Monte Carlo simulations can estimate such mean values. This familiar framework falls apart when the time derivatives do not occur quadratically. The Legendre transformation becomes difficult or so intractable that the Hamiltonian can’t be determined. Even if the Hamiltonian is found, it usually is so complicated that the partition …

An Analysis Of Growth Of The Community Integration Psychological Score In An Ethnically Diverse Population Experiencing Homelessness In A Permanent Supportive Housing Program Using Hierarchical Mixed Modeling, Leah Hollis Puglisi

Mathematics & Statistics ETDs

Hierarchical models are becoming increasingly common in epidemiological and psychological research. When analyzing data from such studies, the nested structure of the data must be taken into account. Mixed modeling in conjunction with hierarchical mixed modeling allows researchers to ask broad questions about the population of interest. Modeling under restricted maximum likelihood estimation (REML), as opposed to full maximum likelihood estimation (ML), increases the accuracy of estimates for the random effects in the model. We use hierarchical mixed modeling under REML estimation to analyze which factors increase “community integration”, a concept and a construct developed and used in the mental …

Gasda, Horton Newsom, Abdulmehdi Ali, Eric J. Peterson, Nina Lanza, Adriana Reyes-Newell, Dorothea Delapp, Chris Yeager, Andrea Labouriau, Roger C. Wiens, Samuel Clegg, Shelbie Legett, Debarati Das

Earth and Planetary Sciences ETDs

Boron has been detected on Mars [Gasda et al., 2017, Das et al., 2019, 2020] within calciumsulfate veins found within clay-rich rocks on Mars by the Mars Science Laboratory (MSL) rover using Laser Induced Breakdown Spectroscopy (LIBS) analysis. Boron plays a vital role in stabilizing ribose on Earth and has been suggested as a key requirement for life [Scorei et al., 2006, 2012; Furukawa et al., 2013, 2017; Becker et al., 2019]. Additionally, boron readily adsorbs to phyllosilicate clay minerals and is often associated with biologic processes in clay soils. The discovery of boron on Mars in proximity to phyllosilicate …

Atom Trapping And Its Role On The Nucleation & Growth Of Platinum Nanoparticles, Deepak Kunwar

Chemistry and Chemical Biology ETDs

Diesel oxidation catalysts deactivate due to Pt sintering, a major problem in automotive industries. To make sure they operate effectively throughout the lifetime of the vehicle, automotive industries are putting an excessive amount of Pt. There is a need to develop a catalyst that serves long term performance with minimal use of Pt. Jones et al^.1 demonstrated that ceria traps Pt atoms. His work generated some logical and valid questions such as what is the mechanism for the formation of anomalously large Pt particles? What is the upper limit of Pt metal loading in the form of single atoms …

Oral Health Literacy Status Of School Staff Members In Southern Minnesota, Gabrielle Sullivan

Radial Basis Densities And The Density Functional-Based Atom-In-Molecule: Designing Charge-Transfer Potentials, Godwin Amo-Kwao

Nanoscience and Microsystems ETDs

Classical potentials that are capable of describing charge transfer and charge polarization in complex systems are of central importance for classical atomistic simulation of biomolecules and materials. Current potentials—regardless of the system—do not generalize well, and, with the exception of highly-specialized empirical potentials tuned for specific systems, cannot describe chemical bond formation and breaking. The charge-transfer embedded atom method (CT-EAM), a formal, DFT-based extension to the original EAM for metals, has been developed to address these issues by modeling charge distortion and charge transfer in interacting systems using pseudoatom building blocks instead of the electron densities of isolated atoms. CT-EAM …

Integrating Deep Learning And Augmented Reality To Enhance Situational Awareness In Firefighting Environments, Manish Bhattarai

Electrical and Computer Engineering ETDs

We present a new four-pronged approach to build firefighter's situational awareness for the first time in the literature. We construct a series of deep learning frameworks built on top of one another to enhance the safety, efficiency, and successful completion of rescue missions conducted by firefighters in emergency first response settings. First, we used a deep Convolutional Neural Network (CNN) system to classify and identify objects of interest from thermal imagery in real-time. Next, we extended this CNN framework for object detection, tracking, segmentation with a Mask RCNN framework, and scene description with a multimodal natural language processing(NLP) framework. Third, …

Exploring Hidden Structure Of The Nearby Universe And The Limits And Capabilities Of Two Neutral Hydrogen Surveys, Monica Sanchez Barrantes

Physics & Astronomy ETDs

We can use the 21 cm neutral hydrogen (HI) emission line to detect galaxies in optically obscured regions, but it is also a faint line that is difficult to detect at higher redshifts. This work presents two HI surveys. The ALFAZOA Survey maps new and predicted large-scale structure across the Galactic plane, and finds a total of 217 completely new galaxies across both of the survey phases. The completeness limits for ALFAZOA Shallow and Deep are presented. Follow-up observations of confused galaxies in ALFAZOA using the VLA determine that confusion in this survey will not cause significant deviations for the …

Evolution Of Brain-Wide Activity In The Awake Behaving Mouse After Acute Fear By Longitudinal Manganese-Enhanced Mri, Taylor W. Uselman, Daniel R. Barto, Russell E. Jacobs, Elaine L. Bearer

Pathology Research and Scholarship

Life threatening fear after a single exposure evolves in a subset of vulnerable individuals to anxiety, which may persist for their lifetime. Yet neither the whole brain's response to innate acute fear nor how brain activity evolves over time is known. Sustained neuronal activity may be a factor in the development of a persistent fear response. We couple two experimental protocols to provoke acute fear leading to prolonged fear: Predator stress (PS), a naturalistic approach to induce fear in rodents; and Serotonin transporter knockout mouse (SERT-KO) that responds to PS with sustained defensive behavior. Behavior was monitored before, during and …

Social Network Centrality, Social Construction Of Knowledge, And Nurse Practitioner Competency In Asynchronous Online Discussions Among Adult Gerontology Acute Care Nurse Practitioner Students, Sharon Schaaf

Organization, Information and Learning Sciences ETDs

The relationships between social network centrality, social construction of knowledge, and nurse practitioner competency among adult gerontology acute care nurse practitioner students participating in asynchronous online discussions were explored. Social network centralities (betweenness, in-degree, out-degree, closeness, and eigenvector) were determined through social network analysis. Social construction of knowledge was assessed by the Interaction Analysis Model (IAM). Nurse practitioner competency was evaluated using the Novice to Expert model. A retrospective exploration of an online discussion board from the College of Nursing at the University of New Mexico was conducted. The centralities of betweenness, closeness, and eigenvector demonstrated a significant relationship with …

Evaluating Public Transit Accessibility In Albuquerque, New Mexico: A Fixed-Route Bus Service Analysis, Risa E. Gutierrez

Civil Engineering ETDs

This research analyzed how residential accessibility to fixed-route bus service in Albuquerque, New Mexico varies by distance, income level, and headway. A literature review investigated components of travel that might deter people from using public transit such as travel distance, sidewalk condition or availability, bus headway, lack of active travel in today’s society, personal and traffic safety, and access equity. Geographic Information System (GIS) mapping was used to determine if low-income neighborhoods have better or worse access to ABQ Ride bus stops relative to medium- or high-income neighborhoods. Residential land use was divided into three economic classes based on 2018 …

Blockchain Based Communication Architectures With Applications To Private Security Networks, Ashley N. Mayle

Computer Science ETDs

Existing communication protocols in security networks are highly centralized. While this naively makes the controls easier to physically secure, external actors require fewer resources to disrupt the system because there are fewer points in the system can be interrupted without the entire system failing. We present a solution to this problem using a proof-of-work-based blockchain implementation built on MultiChain. We construct a test-bed network containing visual imagers and microwave sensor information. These data types are ubiquitous in perimeter security systems and allow a realistic representation of a real-world network architecture. The cameras in this system use an object detection algorithm …

Health Monitoring Using Deep Learning Of Acoustic And Speech Signals, Eric E. Hamke

Electrical and Computer Engineering ETDs

The focus of the research is to identify stress markers in a firefighter's speech. These markers include changes in breathing patterns and changes in the fundamental frequency of an individual’s voice. The breathing patterns are characterized using the number of breaths taken in a minute and the time spent inhaling. These measures are estimated using a Restricted Boltzmann Machine to process a firefighters’ SCBA regulator sounds, as open and closed. The classifications are then combined into continuous intervals. Observing the length of the intervals and the number of interval-starts represents time spent inhaling and the breathing rates (breaths per minute). …

Thermal Mapping And Evaporation Estimation Of Cochiti Lake Using Landsat 8 Imagery, Claudia Jimenez Arellano

Civil Engineering ETDs

Satellite remote sensing (RS) techniques have revolutionized the study of spatial and temporal processes in environmental science and water resources engineering. This study was focused on advancing the understanding of RS techniques to provide estimates of spatial variability of surface water temperature and corresponding evaporation rates for open water.

Evaporation plays a crucial role in water budgets, which is critical knowledge for water management, especially in arid environments. However, there are few methods to estimate its spatial variability, which is relevant because water does not evaporate equally everywhere on a large waterbody. Hence, we cannot assume the calculations of evaporations …
