The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski

Biomedical Sciences ETDs

Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …

Affective Liking Influences Reward Processing In Depression: A Computational Eeg Approach, Garima Singh

Psychology ETDs

Reinforcement learning (RL) enables agents to learn through interaction with their environment. This empowers individuals to optimize actions in complex and dynamic settings. The component of event related potential (ERP) termed as the Reward Positivity (RewP) evidently signifies a fundamental reward prediction error (RPE) associated with rewards. This characteristic implies that it represents a fundamental computational process in the assessment of RL. When a reward is particularly pleasurable or liked by an individual, it tends to elicit an amplified RewP signal, reflecting the heightened positive affect. RPE arises from disparities between anticipated and actual rewarding outcomes and is known to …

Social Tolerance, Cooperation, And Constraint Shape Differentiated Social Relationships In Female Chimpanzees, Stephanie Fox

Anthropology ETDs

In this dissertation, I investigate variables that promote and constrain female-female social relationships in chimpanzees, a species where females disperse at sexual maturity, reside primarily among non-kin as adults, and where fission fusion social structure can reveal how female social behavior responds to different social contexts. I conducted my research using a combination of detailed behavioural data that I collected during a one-year field season (2019-2020) and long-term data (2010-2019) collected by the Kibale Chimpanzee Project. I show that female chimpanzees form stable, differentiated social relationships, which reflect active preferences and variation in social tolerance (Chapter 2); females leverage these …

Applying Data Science And Machine Learning To Understand Health Care Transition For Adolescents And Emerging Adults With Special Health Care Needs, Lisamarie Turk

Nursing ETDs

A problem of classification places adolescents and emerging adults with special health care needs among the most at risk for poor or life-threatening health outcomes. This preliminary proof-of-concept study was conducted to determine if phenotypes of health care transition (HCT) for this vulnerable population could be established. Such phenotypes could support development of future studies that require data classifications as input. Mining of electronic health record data and cluster analysis were implemented to identify phenotypes. Subsequently, a machine learning concept model was developed for predicting acute care and medical condition severity. Three clusters were identified and described (Cluster 1, n …

Land Rich, Cash Poor: Hispanic Subsistence Agri-Culture On Acequia Farms Of Northern New Mexico, 1880-1950s, José A. Rivera Ph.D.

Faculty Publications

Acequia-based agriculture in Hispanic northern New Mexico originated with the arrival of settlers from the central valley of Mexico in the late sixteenth century and later following the Camino Real into the upper Río Grande and its tributaries. The high desert environment required irrigation for food production and survival. Land parcels in the rural villages of northern New Mexico were small, and crop yields were limited to home consumption on a subsistence basis, an economy that lasted well into the territorial period and statehood of New Mexico. Despite a wage economy introduced with the arrival of the railroad around 1880 …

3d Library From Body Size From Unconventional Specimens: A 3d Geometric Morphometrics Approach To Fishes From Ancestral Pueblo Contexts, Jonathan Dombrosky, Thomas F. Turner, Alexandra Harris, Emily Lena Jones

Anthropology Faculty & Staff Publications

Animal body size estimation from zooarchaeological specimens often relies on specific, one-dimensional (i.e., conventional) measures from skeletal elements. Here, we introduce an animal body size estimation technique for archaeological fishes that relies on 3D reference scans and the calculation of centroid size, a standard 3D geometric morphometric proxy measure for organism size. Centroid size-based estimations on whole caudal vertebrae are strongly correlated with a widely accepted measure (i.e., centrum width), but the scalability and flexibility of the centroid size-based approach allows for use on a wide variety of fragmented remains. We use zooarchaeological fish remains (subfamily Ictiobinae) from late pre-Hispanic …

Energetic Tradeoffs, Infection, And Immunity In Wild Chimpanzees Of Uganda And Tanzania, Sarah Renee Phillips

Anthropology ETDs

Infectious disease is a primary source of mortality for most mammal species, but scientists have little understanding of factors driving variation in infection and immunity between individuals, populations, and species in the wild. Life history theory provides an evolutionary framework for delineating distribution of available energy to competing physiological demands, including growth, reproduction, and maintenance. Early life reproduction should be favored over late life survival, but, in long-lived species, reproductive success is strongly tied to survival to old age. Slower pace of reproduction could allow investment in immunity, reducing risk of morbidity and mortality to infectious disease. Additionally, several host …

Eeg Features Of Explore-Exploit Decision-Making In Alcohol Use Disorder, Ethan Campbell

Psychology ETDs

Little research has assessed explore-exploit behavior in addiction using drug cues and even fewer studies have measured the neural activity underlying these behaviors. The present study aims to explore brain mechanisms of disordered decision-making in alcohol use disorder (AUD) through electroencephalography (EEG) during performance of a novelty bandit task with alcohol imagery and using a validated computational model of explore-exploit dynamics. Individuals with AUD (n = 28) and age and sex-matched controls (n = 27) showed differences in choice behavior and showed differences in EEG activity as a function of exploratory behavior, chosen stimulus type, and explore-exploit computational …

Hippocampal Functional Activity Following Prenatal Alcohol Exposure, Ryan E. Harvey

Psychology ETDs

Prenatal alcohol exposure (PAE) is among the most common developmental insults to the nervous system and is characterized by spatial memory disruption. There is a pressing need to identify physiological alterations that help explain this memory impairment. The hippocampal (HPC) formation and connected regions are a compelling candidate for this purpose as they are vital for navigation, spatial memory, and memory consolidation. This document is broken up into 3 main parts, a detailed review of the prior literature followed by several experiments. First, It starts out with a comprehensive review on spatial behavioral impairments following PAE and the synaptic & …

Effects Of Environmental Change On Ancestral Pueblo Fishing In The Middle Rio Grande, Jonathan W. Dombrosky Dr.

Anthropology ETDs

It has long been assumed that fishes were unimportant in the diet of past Pueblo people in the U.S. Southwest. Yet, small numbers of fish remains are consistently recovered from Late pre-Hispanic/Early Historic archaeological sites in the Middle Rio Grande of New Mexico. The end of drought conditions may have impacted food choice and fishing decisions during this time. I use behavioral ecology to understand how fishing could have been an optimal food-getting strategy for Ancestral Pueblo farmers. Stable isotope analysis offers a way to account for environmental change. I provide a refined ¹³C Suess correction model to support …

How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala

Latin American Studies ETDs

Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …

Temporal Information Guides Prefrontal Preparatory Activity, Jacqueline R. Janowich

Shared Knowledge Conference

Proactive preparation for an upcoming goal differs from last-minute reactive adaptation, but it is unclear how preparatory mechanisms change based on when in the future a goal needs to be executed. To assess how timing information is integrated into preparatory control, we designed a novel variant of the Dot Pattern Expectancy task, where each cue signaled both task rule and delay duration (known short, known long, or unknown) between cue and probe. We recorded EEG while healthy young adult participants (n=36) performed this task, and found that delay demands elicited distinct prefrontal preparatory activities. Medial prefrontal amplitude was sensitive to …

The Critical Need For Mental Health Education To Be Mandated In New Mexico's Public Schools, Bonnie L. Murphy

Shared Knowledge Conference

Based on a review of research and best practices in mental health awareness and skills, this inquiry project argues for state legislative policies that would require mental health awareness and skills in the K-12 curriculum. Mental health affects individual accomplishments in every stage of people’s lives beginning in early childhood and throughout the life cycle. Prevention and treatment of mental illness plays a key role in the ability of an individual to cope with loss and develop resiliency and perseverance in challenging times and to make better decisions that improve the individual’s life and the lives of those around them. …

Laterality In The Power Five And Group Of Five Conferences In Women's College Softball, Jon C. Nachtigal

Health, Exercise, and Sports Sciences ETDs

Females in sport are under-represented in data and analysis when compared to their male counterparts. This disparity also applies to women’s softball in comparison to men’s baseball. To help fill this gap, this study evaluated the extent and impact of laterality in women’s college softball’s Power Five and Group of Five conferences from 2015-2017.

This study focused on the extent of a left-sided lateral preference in women’s college softball, possible interactions between throwing hand and batting preference, to what extent the platoon effect exists in the sport, and the extent of positional bias in the sport. As one of the …

Neurocognitive Markers Of Cognitive Control In Schizophrenia And Functional Outcomes, Sephira Ryman

Psychology ETDs

Impaired cognitive function results in decreased objective quality of life and community functioning in schizophrenia, resulting in the largest indirect costs from the disease. Disrupted proactive cognitive control, a form of early selection and active goal maintenance, is hypothesized to underlie the broad cognitive deficits observed in patients with schizophrenia. The current study utilized novel electrophysiological (EEG) analytic approach to examine proactive and reactive cognitive control deficits in schizophrenia patients. Behavioral results highlight that patients exhibited a general reduction in reaction time across two multisensory cognitive control tasks, with selective deficits on proactive conditions relative to reactive conditions. The relative …

Moderate Prenatal Alcohol Exposure Impairs Performance In An Object-Place-Paired-Associate Task, Lilliana May Sanchez

Psychology ETDs

Memory impairments, including spatial and object processing, are often observed in individuals with Fetal Alcohol Spectrum Disorder. Much attention has been directed towards the hippocampus, which displays significant alterations after moderate prenatal alcohol exposure (PAE). In the present study, we tested a moderate PAE rat model in an object-place-paired-associate (OPPA) task, previously shown to require hippocampal processing. The OPPA task was composed of training rats to discriminate between an identical pair of objects presented in 180° opposite arms of a radial arm maze. Animals were given a total of 10 trials per day over 14 consecutive days of training and …

Functional Neural Connectivity Associated With Moral Processing In Healthy And Antisocial Samples, Samantha Jean Fede

Psychology ETDs

Although research finds that brain abnormalities during moral decisions underlie traits that lead to crime, understanding of these neural dynamics is limited. Here we use two samples to explore the role network engagement and components during moral processing. We used independent component analysis and functional network connectivity analysis to examine hemodynamic response during an fMRI task of moral processing. Eighty-four community and 539 incarcerated adult men and women participated; MANCOVA and machine learning algorithms were used to identify individual and group differences in both samples. We found patterns of neural engagement and connectivity consistent with proposed models of moral cognition …

Relationship Between Structure And Functional Connectivity Within The Default Mode Network, Andrei A. Vakhtin

Psychology ETDs

We proposed a novel measure of conceptualizing dynamic functional network connectivity (FNC) in the human brain using flexibility of functional connectivity (fFC), which captures the variance of functional connectivity across time. In task-free fMRI scans (N = 122), this measure was demonstrated to correspond to the underlying structural connectivity (SC) within the default mode network (DMN), while static functional connectivity (sFC) did so to a relatively low degree. As SC likely does not develop to facilitate task-free brain function, but rather to integrate information during cognitive engagement, we argue that fFC can estimate the potential functional connectivity exhibited outside of …

Analyzing The Rio Chama Flow Project’S Capacity To Implement Adaptive Management, Avery Olshefski

Water Resources Professional Project Reports

The Rio Chama is the main tributary to the Rio Grande in New Mexico. Several reservoirs were built on the Rio Chama to store water for downstream users, which has led to the river section becoming highly managed, resulting in negative ecological effects. Approximately 400,000 AF per year of water is conveyed through the system without considerable consumptive amounts, 96,200 AF of which were added with the San Juan-Chama trans-basin diversion, creating more water in the system then historically available. Therefore, the flow between the El Vado and Abiquiu Reservoirs has the potential to be optimized in order to provide …

Twenty-Eight Years Of The Us-Lter Program: Experience, Results, And Research Questions, James R. Gosz, Robert B. Waide, John J. Magnuson

Long Term Ecological Research Network

The U.S. Long Term Ecological Research program (hereafter US-LTER) concentrates on ecological processes that play out at the time scales spanning decades to centuries. This focuses US-LTER research between the most common time scales for ecological studies (1-3 years; Tilman 1989; Figure 1) and the much longer temporal fact of disciplines such as paleoecology. The importance of the decade-to-century time scale is particularly evident in light of the rapid changes in ecological forcing functions that are occurring at a broad range of spatial scales (Millennium Ecosystem Assessment 2005, Intergovernmental Panel on Climate Change 2007). Long-term data sets from programs such …

Steroid Hormones And Human Variability: Correlation Of Androgen Levels With Age And Occupation In Normal Subjects, Frances E. Purifoy

Anthropology ETDs

The endocrine system, coordinated with the central nervous system, is an important mediator of the genetic-environmental interactions which influence the development of human phenotypes. For this reason, endocrine parameters provide an important source of information for anthropological studies. This research focuses on the role of the endocrine system in normal human variability, with emphasis on the steroid hormones, which affect numerous aspects of mammalian morphology, physiology and behavior. Preceding the discussion of original research is an extensive literature review on hormonal variation in each of three areas: 1) sex and inter-individual variation, with emphasis on behavior; 2) variation with age, …

The Distribution And Ecology Of The Hispid And Least Cotton Rat (Genus Sigmodon) In New Mexico, John S. Mohlhenrich

Biology ETDs

Two species of cotton rats, Sigmodon minimus Mearns (least cotton rat) and S. hispidus Baird (hispid cotton rat), occur in the Rio Grande Valley of New Mexico. The northernmost published record-station for S. hispidus is near Scorro, Scorro County ( Bailey, 1931: 167), and that S. minimus is near Isleta, Bernalillo County (Ivey, 1947: 498 and map). When recent field work by the author revealed the presence of both species in the Rio Grande Valley north of these published record-stations the problem arose whether the range extensions were the result of a recent northward extension of the range of the …

The Ethnobotany Of The Isleta Indians, Volney H. Jones

Anthropology ETDs

This study is an outgrowth of the increasing interest in the history, ethnology, and archaeology of the Pueblo Indians of the Southwest. Although much research has been done in this very fertile field, new and fascinating problems are constantly pre­senting themselves.

When one states that the environment greatly influences a people he speaks truisms and common knowledge. The arid South­west with its distinctive flora offers an unusual environment to which the Indian had adapted himself remarkably well. The object in general of this problem has been to study the reciprocal re­lation between the Isleta Indian and his plant environment; speci­fically, …
