Informed Consent: Foundations And Applications, Joanna Smolenski
Informed Consent: Foundations And Applications, Joanna Smolenski
Dissertations, Theses, and Capstone Projects
Since its advent in the 20th century, informed consent has become a cornerstone of ethical healthcare, and obtaining it a core obligation in medical contexts. In my dissertation, I aim to examine the theoretical underpinnings of informed consent and identify what values it is taken to protect. I will suggest that the fundamental motivation behind informed consent rests in something I’ll call bodily self-sovereignty, which I argue involves a coupling of two groups of values: autonomy and non-domination on the one hand, and self-ownership and personal integrity on the other. I will then go on to consider two 'case …
Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern
Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern
Dissertations, Theses, and Capstone Projects
Coastal resiliency is becoming significantly more critical to the livelihood of coastal communities as the frequency and intensity of storm events increases and is exacerbated by rising sea levels due to climate change. In October 2012 Superstorm Sandy impacted the New York-New Jersey area costing over $70 billion in storm damages and 147 lives lost, as storm surges surpassed record highs for the region. Protruding more than 100 miles into the Atlantic Ocean with over 1,000 miles of shoreline, Long Island is particularly vulnerable to the increasingly ferocious and numerous storms as well as the rising sea levels that climate …
Contributions Of Reward Identity And Time Prediction Errors To Pavlovian Learning, Daniel B. Siegel
Contributions Of Reward Identity And Time Prediction Errors To Pavlovian Learning, Daniel B. Siegel
Dissertations, Theses, and Capstone Projects
Some models of associative learning attempt to explain effects such as blocking and unblocking as reflecting a prediction error (PE): Associative strength, and thereby learning, are said to be greater when the unconditioned stimulus (US) received following a cue deviates from one’s expectations. Some models of PE-motivated behavior and PE-relevant brain activity represent the US as a single quantitative variable for outcome value, and that learning therefore only occurs when outcome value differs from expectations. There is growing evidence to suggest that changes in other dimensions of reward, such as identity and timing, also contribute to learning. In Experiment 1, …
Vertebrate Scavenger Diversity And Ecosystem Services Along An Elevational Gradient In Central Nepal, Aishwarya Bhattacharjee
Vertebrate Scavenger Diversity And Ecosystem Services Along An Elevational Gradient In Central Nepal, Aishwarya Bhattacharjee
Dissertations, Theses, and Capstone Projects
A growing number of studies recognize the ecological significance of vertebrate scavengers, and several species belonging to this diverse, functional guild are of high conservation importance around the globe. Studies on taxonomic and functional components of biodiversity often use elevation gradients to comprehensively examine patterns and drivers across multiple spatial scales. Yet, there are relatively few elevational studies on large vertebrates or multi-taxa guilds, and the related variation of their ecosystem services. In particular, scavenger research has largely focused on local-scale studies or regional/global comparisons of local-scale investigations. Moreover, these studies primarily consider taxonomic community characteristics and the patterns of …
A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab
A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab
Dissertations, Theses, and Capstone Projects
Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …
The Role Of Placental Genes On Intellectual Disability And Developmental Delay, Maedot A. Yidenk
The Role Of Placental Genes On Intellectual Disability And Developmental Delay, Maedot A. Yidenk
Dissertations, Theses, and Capstone Projects
The complex interaction between gene expressions and environmental factors plays a key role in the pathogenesis of various diseases, including neurodevelopmental disorders (Lenroot & Giedd, 2008). This study aimed to evaluate first, the magnitude of association between placental gene Methyl-CpG Binding Protein 2 (MeCP2) and intellectual disability (ID) in the offspring and second, the synergy between placental gene Forkhead box protein 1(FOXP1) and developmental delay (DD) in the offspring. We focused on assessing two specific paradigms, i) placental gene expressions of MeCP2 among children that have ID vs. children without ID; and ii) placental gene expression of …
The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria
The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria
Dissertations, Theses, and Capstone Projects
Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …
Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle
Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle
Dissertations, Theses, and Capstone Projects
Post-traumatic stress disorder (PTSD) is a trauma-related disorder characterized by intense fearful memory formation. Women are twice as likely as men to develop PTSD, indicating there may be sex differences in the underlying neural circuits. Given that serotonin (5-HT) dysfunction is implicated in PTSD, and 5-HT modulates fear learning, we investigated whether there are sex differences in the modulation of fear learning by 5-HT. We administered the selective serotonin reuptake inhibitor (SSRI) citalopram (20mg/kg or 10m/kg, i.p.) once to male and female mice prior to auditory fear conditioning and tested the effects on fear memory the next day. We found …
Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska
Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska
Dissertations, Theses, and Capstone Projects
Working memory (WM) is the temporary storage of information to accomplish a future goal. The WM delay period is the time after encoding but before retrieval when information is being maintained, typically in the absence of relevant stimuli. Understanding how the brain supports maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM research is how information is stored during this delay period. One …
Early Emotion Regulation In The Children Of Superstorm Sandy, Jessica L. Buthmann
Early Emotion Regulation In The Children Of Superstorm Sandy, Jessica L. Buthmann
Dissertations, Theses, and Capstone Projects
Rising prevalence of childhood psychopathology mandate investigation into the antecedents of symptom onset. Growing evidence shows prenatal maternal stress experienced in utero is a strong contributor to offspring neurodevelopmental deficits, including emotion dysregulation, a core feature of many types of psychopathology. This dissertation summarizes a body of work studying children prenatally exposed to maternal stress related to a natural disaster, Superstorm Sandy (i.e., storm stress). This work includes six experiments conducted in the framework of the Developmental Origins of Health and Disease (DOHaD) hypothesis. The DOHaD hypothesis posits that developmental disruptions, like storm stress exposure, during a critical period of …
Learning To Feel Safe: A Translational Study Of The Influence Of Safety Learning On Anxiety-Related Overgeneralized Fear, Hyein Cho
Dissertations, Theses, and Capstone Projects
Anxiety disorders are among the most common mental health diagnoses, affecting about a third of the population in their lifetime. However, approximately a third of individuals with anxiety do not respond to current treatment approaches, highlighting the need to identify additional potential therapeutic mechanisms. Safety learning is one such mechanism, but methodological challenges and a dearth of research have prevented the field from advancing the understanding of the role of safety learning in the etiology and remediation of anxiety disorders. Animal research, using single-cued safety learning paradigms, has yielded promising early findings, demonstrating that safety learning directly reduces anxiety-related behaviors …

Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …
Influence Of Demographic, Clinical, And Neuroimaging Variables On Neuropsychological Recovery Trajectories After Moderate-To-Severe Traumatic Brain Injury, Elizabeth J. Leif
Influence Of Demographic, Clinical, And Neuroimaging Variables On Neuropsychological Recovery Trajectories After Moderate-To-Severe Traumatic Brain Injury, Elizabeth J. Leif
Dissertations, Theses, and Capstone Projects
Traumatic brain injury (TBI) is prevalent in people of all ages and all walks of life. Cognitive deficits are common after TBI and the recovery patterns are known to be variable across individuals. The current study investigates diffuse axonal injury (DAI), cerebral blood flow (CBF), and focal lesions, in addition to post-traumatic amnesia (PTA), as possible predictors of cognitive trajectory in moderate-to-severe TBI patients. Cognitive trajectory was evaluated with a battery of neuropsychological tests that were combined into three domains: processing speed, verbal learning, and executive function. Patients (N=44) were tested three times at 3, 6, and 12 months post-injury. …
