Organizational Culture: An Examination Of The Role Of Leadership In Neutralizing The Negative Effects Of Technostress During Operational Shifts, David P. Kirkland

All-Inclusive List of Electronic Theses and Dissertations

COVID-19 created a support problem for public universities across the United States and required that IT departments and professionals alter how they performed in 2020, and perhaps beyond. IT professionals tasked with safeguarding large amounts of data were required to shift to a teleworking posture to continue offering a similar level of service as previously expected. In addition to the technological shift that organizations experienced because of COVID-19, leadership challenges also impacted IT departments across the United States. The rapid shift of operational duties has the propensity to increase technology-related stress, due to employee perception of being successful in their …


Vte And Anticoagulation In Menstruating Women, Ida Micaily, Bethany T. Samuelson Bannow Dec 2021

Vte And Anticoagulation In Menstruating Women, Ida Micaily, Bethany T. Samuelson Bannow

Department of Medicine Faculty Papers

Women of childbearing potential have a high prevalence of venous thromboembolism (VTE) due to high estrogen states, such as pregnancy and the use of estrogen-containing contraceptives. Abnormal uterine bleeding (AUB) affects up to two-thirds of menstruating women on anticoagulation (AC), and can severely impair a woman's quality of life. Rates of heavy menstrual bleeding (HMB) and other forms of AUB including inter-menstrual and postmenopausal bleeding are consistently underreported in the original clinical trials utilizing AC. VTE can occur at any time in a woman's life, and the aim of this review article is to discuss the current landscape of literature …


Radio Carbon - Hybrid Documentary Process, Robert Stokes Dec 2021

Radio Carbon - Hybrid Documentary Process, Robert Stokes

Theses

Radio Carbon is a documentary made using a methodology for creating conscious digital video projects with a process privileging respect for crew, subject, and environment over the needs of a commercial, or market driven product. The guidelines imposed by this method are fluid, and project-specific in terms of their exact interpretation for each film. This project is meant to demonstrate a production style that allows for work to be made by the participants without a dominating creative force at every stage of production. This is made possible through the introduction of chance operations at several key points along the production …


A Distributed Fmri-Based Signature For The Subjective Experience Of Fear, Feng Zhou, Weihua Zhao, Ziyu Qi, Yayuan Geng, Shuxia Yao, Keith M. Kendrick, Tor D. Wager, Benjamin Becker Dec 2021

A Distributed Fmri-Based Signature For The Subjective Experience Of Fear, Feng Zhou, Weihua Zhao, Ziyu Qi, Yayuan Geng, Shuxia Yao, Keith M. Kendrick, Tor D. Wager, Benjamin Becker

Dartmouth Scholarship

The specific neural systems underlying the subjective feeling of fear are debated in affective neuroscience. Here, we combine functional MRI with machine learning to identify and evaluate a sensitive and generalizable neural signature predictive of the momentary self-reported subjective fear experience across discovery (n = 67), validation (n = 20) and generalization (n = 31) cohorts. We systematically demonstrate that accurate fear prediction crucially requires distributed brain systems, with important contributions from cortical (e.g., prefrontal, midcingulate and insular cortices) and subcortical (e.g., thalamus, periaqueductal gray, basal forebrain and amygdala) regions. We further demonstrate that the neural representation of subjective fear …


Entropy-Based Metrics For Predicting Choice Behavior Based On Local Response To Reward, Ethan Trepka, Mehran Spitmaan, Bilal A. Bari, Vincent D. Costa, Jeremiah Y. Cohen, Alireza Soltani Dec 2021

Entropy-Based Metrics For Predicting Choice Behavior Based On Local Response To Reward, Ethan Trepka, Mehran Spitmaan, Bilal A. Bari, Vincent D. Costa, Jeremiah Y. Cohen, Alireza Soltani

Dartmouth Scholarship

For decades, behavioral scientists have used the matching law to quantify how animals distribute their choices between multiple options in response to reinforcement they receive. More recently, many reinforcement learning (RL) models have been developed to explain choice by integrating reward feedback over time. Despite reasonable success of RL models in capturing choice on a trial-by-trial basis, these models cannot capture variability in matching behavior. To address this, we developed metrics based on information theory and applied them to choice data from dynamic learning tasks in mice and monkeys. We found that a single entropy-based metric can explain 50% and …


High-Level Cognition During Story Listening Is Reflected In High-Order Dynamic Correlations In Neural Activity Patterns, Lucy L.W. Owen, Thomas H. Chang, Jeremy R. Manning Dec 2021

High-Level Cognition During Story Listening Is Reflected In High-Order Dynamic Correlations In Neural Activity Patterns, Lucy L.W. Owen, Thomas H. Chang, Jeremy R. Manning

Dartmouth Scholarship

Our thoughts arise from coordinated patterns of interactions between brain structures that change with our ongoing experiences. High-order dynamic correlations in neural activity patterns reflect different subgraphs of the brain’s functional connectome that display homologous lower-level dynamic correlations. Here we test the hypothesis that high-level cognition is reflected in high-order dynamic correlations in brain activity patterns. We develop an approach to estimating high-order dynamic correlations in timeseries data, and we apply the approach to neuroimaging data collected as human participants either listen to a ten-minute story or listen to a temporally scrambled version of the story. We train across-participant pattern …


Exercise Routine Change Is Associated With Prenatal Depression Scores During The Covid-19 Pandemic Among Pregnant Women Across The United States, Theresa E. Gildner, Elise J. Laugier, Zaneta M. Thayer Dec 2021

Exercise Routine Change Is Associated With Prenatal Depression Scores During The Covid-19 Pandemic Among Pregnant Women Across The United States, Theresa E. Gildner, Elise J. Laugier, Zaneta M. Thayer

Dartmouth Scholarship

Background The COVID-19 pandemic has negatively affected physical and mental health worldwide. Pregnant women already exhibit an elevated risk for depression compared to the general public, a pattern expected to be exacerbated by the pandemic. Certain lifestyle factors, including moderate exercise, may help support mental health during pregnancy, but it is unclear how the pandemic may impact these associations across different locations. Here, we test whether: (i) reported exercise routine alterations during the pandemic are associated with depression scores; and, (ii) the likelihood of reporting pandemic-related exercise changes varies between women living in metro areas and those in non-metro areas. …


White Matter Abnormalities In Adults With Bipolar Disorder Type-Ii And Unipolar Depression, Anna Manelis, Adriane Soehner, Yaroslav O. Halchenko, Skye Satz, Rachel Ragozzino, Mora Lucero, Holly A. Swartz, Mary L. Phillips, Amelia Versace Dec 2021

White Matter Abnormalities In Adults With Bipolar Disorder Type-Ii And Unipolar Depression, Anna Manelis, Adriane Soehner, Yaroslav O. Halchenko, Skye Satz, Rachel Ragozzino, Mora Lucero, Holly A. Swartz, Mary L. Phillips, Amelia Versace

Dartmouth Scholarship

Discerning distinct neurobiological characteristics of related mood disorders such as bipolar disorder type-II (BD-II) and unipolar depression (UD) is challenging due to overlapping symptoms and patterns of disruption in brain regions. More than 60% of individuals with UD experience subthreshold hypomanic symptoms such as elevated mood, irritability, and increased activity. Previous studies linked bipolar disorder to widespread white matter abnormalities. However, no published work has compared white matter microstructure in individuals with BD-II vs. UD vs. healthy controls (HC), or examined the relationship between spectrum (dimensional) measures of hypomania and white matter microstructure across those individuals. This study aimed to …


A Framework To Identify Structured Behavioral Patterns Within Rodent Spatial Trajectories, Francesco Donnarumma, Roberto Prevete, Domenico Maisto, Simone Fuscone, Emily M. Irvine, Matthijs A.A. Van Der Meer, Caleb Kemere, Giovanni Pezzulo Dec 2021

A Framework To Identify Structured Behavioral Patterns Within Rodent Spatial Trajectories, Francesco Donnarumma, Roberto Prevete, Domenico Maisto, Simone Fuscone, Emily M. Irvine, Matthijs A.A. Van Der Meer, Caleb Kemere, Giovanni Pezzulo

Dartmouth Scholarship

Animal behavior is highly structured. Yet, structured behavioral patterns—or “statistical ethograms”—are not immediately apparent from the full spatiotemporal data that behavioral scientists usually collect. Here, we introduce a framework to quantitatively characterize rodent behavior during spatial (e.g., maze) navigation, in terms of movement building blocks or motor primitives. The hypothesis that we pursue is that rodent behavior is characterized by a small number of motor primitives, which are combined over time to produce open-ended movements. We assume motor primitives to be organized in terms of two sparsity principles: each movement is controlled using a limited subset of motor primitives (sparse …

Dartmouth Scholarship

The brain systems underlying placebo analgesia are insufficiently understood. Here we performed a systematic, participant-level meta-analysis of experimental functional neuroimaging studies of evoked pain under stimulus-intensity-matched placebo and control conditions, encompassing 603 healthy participants from 20 (out of 28 eligible) studies. We find that placebo vs. control treatments induce small, widespread reductions in pain-related activity, particularly in regions belonging to ventral attention (including mid-insula) and somatomotor networks (including posterior insula). Behavioral placebo analgesia correlates with reduced pain-related activity in these networks and the thalamus, habenula, mid-cingulate, and supplementary motor area. Placebo-associated activity increases occur mainly in frontoparietal regions, with high …

Testing For Cognitive Deficits After Mild Traumatic Brain Injury Using The Automated Neuropsychological Assessment Metric And Dual-Task Assessments, Jasmin Mabry Dec 2021

Testing For Cognitive Deficits After Mild Traumatic Brain Injury Using The Automated Neuropsychological Assessment Metric And Dual-Task Assessments, Jasmin Mabry

University Honors Theses

Cognitive deficits are common following mTBI. DT gait assessments and seated computerized exams are often used for evaluating those deficits. Little is known about DT gait and neurocognitive performance in a chronic population. We compared people with chronic mTBI and subacute mTBI to healthy controls (HC) on DT gait and neurocognitive performance and explored the relationship of DT gait performance with a traditional neurocognitive (TNC) exam.

Subjects completed a computerized TNC - the ANAM - and a motor-cognitive DT test which assessed both DT motor performance as well as the cognitive task accuracy. The DT test consisted of subjects walking …


The Impact Of The Menstrual Cycle On Female Performance In Athletics, Calli Doan Dec 2021

The Impact Of The Menstrual Cycle On Female Performance In Athletics, Calli Doan

Senior Honors Theses

Female hormones, key to preparing a woman's body for childbirth, work in a magnificent, cyclical manner. It can be expected that these hormones, with the role of preparing a woman's body to conceive a child and deliver a life safely into the world, would have a large impact on the health of the female, especially when it comes to athletics. Numerous studies conducted to understand the full extent of the effect of reproductive hormones on the female body have shown that these hormones influence not only menstruation, but also various physiological and psychological elements. Such effects can certainly impact athletic …


Maternal Mortality: A Growing Health Inequity In America, Michala Geraty Dec 2021

Maternal Mortality: A Growing Health Inequity In America, Michala Geraty

Senior Honors Theses

The United States (U.S.) is known for its quest for knowledge, innovation, and advancements in all disciplines. However, it has the highest maternal mortality ratio (MMR) among developed nations. The US MMR increased from 12.7 to 17.4 per 100,000 live births between 2007 and 2018. Over 60% of these deaths are preventable, indicating room for improvement. African American or non-Hispanic Black women are disproportionately affected, at over twice the rate of their non-Hispanic White and Hispanic counterparts. The proximal (e.g., individual level) determinants have not been able to fully explain these inequities. Using the socio-ecological model and the social determinants …


The Meaning Of Movement: Using Motion Design To Enrich Words For Deaf And Hard Of Hearing Children, Hannah Elyse Colasurdo Dec 2021

The Meaning Of Movement: Using Motion Design To Enrich Words For Deaf And Hard Of Hearing Children, Hannah Elyse Colasurdo

Masters Theses

This thesis aims to address challenging areas of vocabulary for deaf and hard of hearing children by developing an open resource for students, parents, teachers, and content creators that utilizes motion to enhance written words for deaf and hard of hearing children. This research seeks to study the means of nonverbal communication such as body language expression and paralinguistic prosody (i.e., tone, intonation, volume, and pitch) qualities within the framework of graphic design through motion design. Body movement and expression are essential during face-to-face communication, but written language lacks such context clues. Additionally, the hard of hearing may not fully …


Item-Specific And Relational Encoding, But Not Warnings, Are Effective At Reducing The Illusion Of Competence, Emily Cates Dec 2021

Item-Specific And Relational Encoding, But Not Warnings, Are Effective At Reducing The Illusion Of Competence, Emily Cates

Honors Theses

Metamemory, or the ability to understand the capacities of one’s own memory, is an important part of the learning process. One method for assessing metamemory is through the Judgment of Learning (JOL) task in which participants are asked to judge the likelihood of correctly remembering a target word in a cue-target word pair when only presented with a cue word at test. The associative direction of the cue-target pair has been shown to affect the accuracy of JOLs. Unlike forward pairs (e.g., credit-card), in which JOLs accurately predict recall, an illusion of competence has been reported for backward associates (e.g., …


Implementing Mindfulness Meditation To Reduce Nurse Burnout, Jannelle V. Sanchez Dec 2021

Implementing Mindfulness Meditation To Reduce Nurse Burnout, Jannelle V. Sanchez

Electronic Theses and Dissertations

Abstract

There will be an estimated shortage of 100,000 nurses by the year 2022, with 500,000 seasoned nurses retiring. The nursing profession has recently experienced a devastating pandemic that left no time to combat the detrimental effects of burnout, specifically for intensive care nurses, who are the frontline workers of a physically and psychologically draining working environment conducive to burnout. Nurses experience burnout for a mixture of reasons, but mainly it is due to the lack of interventions to help them combat the disease. Mindfulness meditation represents an interventional tool that has been shown to reduce the negative stressors associated …

Amplifying The "A" In Steam Education, Grace Floerke Dec 2021

Amplifying The "A" In Steam Education, Grace Floerke

Honors College Theses

This paper discusses the importance of teachers implementing STEAM education in the classroom. Previously, science, technology, engineering, and mathematics (abbreviated as STEM) education was used as a tool to prepare students to excel in career fields that are projected to grow in the near future. However, recently the acronym was changed to STEAM to add “the arts” to the original acronym. It is imperative that the arts are seen as an equal to STEM, as they can complement and enhance the goals STEM is trying to reach. Since not all students possess the same interest, ways of learning, or abilities, …

Young And Dangerous: The Role Of Youth In Risk Assessment Instruments, Ingrid Yin Dec 2021

Young And Dangerous: The Role Of Youth In Risk Assessment Instruments, Ingrid Yin

Michigan Law Review

States are increasingly adopting risk assessment instruments (RAIs) to help judges determine the appropriate type and length of punishment for an offender. Although this sentencing practice has been met with a wide variety of scholarly criticism, there has been virtually no discussion of how RAIs treat youth as a strong factor contributing to a high risk score. This silence is puzzling. Not only is youth undoubtedly the most powerful risk factor in most RAIs, but youth also holds a special place in the criminal justice system as a “mitigating factor of great weight.” This Comment presents the first in-depth critique …


All God's Children: An Exploratory Study Of Factors To Promote Inclusion Of Autistic Children Within Local Church Congregations, David John Scott Quel Dec 2021

All God's Children: An Exploratory Study Of Factors To Promote Inclusion Of Autistic Children Within Local Church Congregations, David John Scott Quel

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to understand the gap that exists within the literature concerning the parent’s perspective for incorporating Autistic individuals into the life of the church. The theory guiding this study is Maslow’s hierarchy of needs. In Maslow’s hierarchy, there are five level of needs. These areas are physical needs, security needs, love and belonging, esteem needs and self-actualization. These are the most basic needs whether someone is disabled, has special needs, or has no problems at all. The problem remains, far too often, those individuals who are on the Autistic spectrum are looked at as …


Complex Predicates In Southern Turkmen: A Role And Reference Grammar Analysis, Nathaniel Andrew Shaver Dec 2021

Complex Predicates In Southern Turkmen: A Role And Reference Grammar Analysis, Nathaniel Andrew Shaver

Theses and Dissertations

This thesis uses the concepts of nexus and juncture, as articulated by Role and Reference Grammar, to examine complex verbal constructions found in four collected texts. These texts were collected from four Southern Turkmen (or Turkmen of Afghanistan) speakers. Through transcribing, glossing, and analyzing these texts, a number of complex predicates were identified. These were then described according to their various nexus juncture types. Three nexus juncture varieties were represented in the collected texts. These include clausal coordination, clausal subordination, and core cosubordination. Although not represented in the texts, it was possible to elicit three other provisional nexus juncture varieties. …

A Network Linking Scene Perception And Spatial Memory Systems In Posterior Cerebral Cortex, Adam Steel, Madeleine M. Billings, Edward H. Silson, Caroline E. Robertson Dec 2021

A Network Linking Scene Perception And Spatial Memory Systems In Posterior Cerebral Cortex, Adam Steel, Madeleine M. Billings, Edward H. Silson, Caroline E. Robertson

Dartmouth Scholarship

The neural systems supporting scene-perception and spatial-memory systems of the human brain are well-described. But how do these neural systems interact? Here, using fine-grained individual-subject fMRI, we report three cortical areas of the human brain, each lying immediately anterior to a region of the scene perception network in posterior cerebral cortex, that selectively activate when recalling familiar real-world locations. Despite their close proximity to the scene-perception areas, network analyses show that these regions constitute a distinct functional network that interfaces with spatial memory systems during naturalistic scene understanding. These “place-memory areas” offer a new framework for understanding how the brain …
