Oldowan Tool Behaviors Through Time On The Homa Peninsula, Kenya, Emma M. Finestone

Dissertations, Theses, and Capstone Projects

The adaptive significance of tool use to genus Homo is a central theme in human origins. However, what we know from the early Oldowan sites suggests that persistent technology may have begun as an opportunistic behavior with minimal investment, rather than a habitual and widespread adaptive revolution. This dissertation seeks to investigate investment in Oldowan tool production on the Homa Peninsula, Kenya, considering raw material selection, transport, and lithic production at two newly discovered Oldowan localities: Nyayanga (ca. 2.6 Ma) and Sare River (ca. 1.7 Ma).

The first section of this dissertation outlines a method that enables the comparison of …

Environmental Adaptations And Agency: An Ecological Reframing Of Design And Implementation Practices For Disability, Jennifer Adler

Dissertations, Theses, and Capstone Projects

This multi-phase dissertation explores the role of agency and participation in the successful implementation of adaptations for disability. Utilizing an online survey examining the ways people acquire and adapt assistive technologies as well as a series of comprehensive collaboratively constructed “Adaptation Stories,” it examines the acquisition experiences of a sample of those who rely on adaptations and assistive devices.

Quantitative analysis of survey data suggests significant correlations between overall satisfaction with feelings of functional efficacy, overall satisfaction with involvement, overall satisfaction with perceived receptivity of the team, functional efficacy with involvement, functional efficacy with receptivity of team, as well as …

Getting The Benefit Of The Doubt: The Effect Of Randomization Ratio On The Placebo Response, Taiki Matsuura

Dissertations, Theses, and Capstone Projects

Placebos are commonly employed in clinical trials as inactive treatments to which experimental treatments are compared against in order to control for psychological “noise.” Randomized double-blind placebo control studies are considered the “gold standard” in epidemiologic research because they can provide the strongest possible evidence of causation if designed correctly (Hulley, Cummings, Browner, & Grady, 2007). One phenomenon that poses a threat to the integrity of this evidence is the placebo response (PR), or referred to as the “placebo effect.” Expectancy is considered a central PR mechanism and boasts the most empirical support among all proposed mechanisms. Expectancy is not …

The Role Of The Direct And Indirect Basal Ganglia Pathways In The Learning, Performance, And Goal-Directed Control Of Action Sequences, Eric Garr

Dissertations, Theses, and Capstone Projects

Animals engage in intricately woven action sequences that are constructed from trial-and-error learning, but the mechanisms by which the brain links together individual actions which are later recalled as fluid chains of behavior are not fully understood. The aim of this dissertation is to investigate the learning and goal-directed control of action sequences in rats. Experiment 1 addresses a question that comes out of a reinforcement learning model of action sequencing: how does the extent of training change how the performance of an action sequence is impacted by reward devaluation. The data show that action sequences remain goal-directed overall regardless …

Impact Of Religiosity And Level Of Acculturation On Cultural Alignment: An Exploration Of Terror Management Mechanisms Among Muslim American Women, Farah T. Goheer

Dissertations, Theses, and Capstone Projects

ABSTRACT

Impact of Religiosity and Level of Acculturation on Cultural Alignment: An Exploration of Terror Management Mechanisms among Muslim American Women

by

Farah Taha Goheer, M.A.

Advisor: Joel Sneed, Ph.D.

Background: Terror management theory (TMT) is based upon the notion that human beings require ongoing psychological protection from the unyielding, existential threat of death. A large body of evidence has shown that human beings manage death-related terror by aligning with and endorsing the dominant views of their cultural worldviews. Notably, as immigrants experience a new culture, worldviews become rearticulated to incorporate elements of host and heritage cultures. However, it is …

Hyaluronan At The Brain-Environment Interface, Donald M. Thevalingam

Dissertations, Theses, and Capstone Projects

Hyaluronan (HA; Hyaluronic Acid), a primary scaffolding component of the brain extracellular matrix, serves as an integral structural component to the brain extracellular space (ECS). The fossorial African naked mole-rat (Heterocephalus glaber; NM-R), a mammal which lives in a low-oxygen environment and is capable of tolerating hypoxia and hypercapnia, has been shown to synthesize and sustain a unique high-molecular-mass variant of hyaluronan macromolecule (HMM-HA). This body of work highlights HA’s role in mediating the interplay between brain ECM composition, ECS structure, and cell viability.

Here we employ the NM-R as a unique animal model to observe the role of the …

Murine Genetic Variance In Sugar And Fat-Conditioned Flavor Preferences: Roles Of Dopamine, Opioid And Nmda Receptors And Nutritive Sensing, Tamar T. Kraft

Dissertations, Theses, and Capstone Projects

As obesity and diabetes have emerged as a severe public health crisis, understanding the mechanisms underlying the consumption of sugars and fats has become a topic of vigorous study. From a biological standpoint, genetic dispositions, neurochemical and hormonal influences, and predetermined orosensory and postingestive signals that modulate the hunger and satiety process may govern physiological aspects of the obesity puzzle. In addition to an innate appetite and attraction for simple carbohydrates and fats, learning plays an important role in modulating preferences for sugar- and fat-rich foods in rodents, including inbred mouse strains. Marked genetic variance has been observed among murine …

How Racial Injustice Causes Ignorance, Eric Bayruns

Dissertations, Theses, and Capstone Projects

According to a (Jones and Saad) 2016 Gallup poll 69% of US whites and 32% of US blacks believe that blacks and whites have equal opportunity in the US job market. Much ink has been spilt showing that this belief is false (Alcoff 2015; Anderson 2010; Bertrand and Mullainathan 2003; Fricker 2007; McConahay 1983; Mills 1997; Mills 2007; Stanley 2015). But if its falsity is well publicized, then why do so many people persist in believing this falsehood? In this dissertation, I argue that racial injustice and whites’ current dominant-group status explains why such a high percentage of people in …

Infinity Wars: Post 9/11 Superhero Films And American Empire, Peter J. Bruno

Dissertations, Theses, and Capstone Projects

In the last two decades, superhero films have accounted for some of the most popular and financially lucrative films of all time. This thesis analyzes some of the aesthetic and ideological dimensions of various superhero films following their post 9/11 boom. Beginning with America’s response to the events of 9/11 and a subsequent retreat into a Manichean world of good versus evil, I introduce the term “empirical reality” in order to account for the ways daily American life is shielded from the worst effects of U.S. foreign policy. On screen this manifests by perpetuating the myth of the “clean war” …

An Evolutionary Perspective On Foraging Strategies And Group Dynamics In Bio-Social Inspired Cognitive Radio Networks, Anna Wisniewska

Dissertations, Theses, and Capstone Projects

Saturation of wireless channels is inevitable as the number of wireless devices grows exponentially in an environment of limited radio spectrum capacity. Cognitive radio technology has been proposed to relieve overcrowded spectrum resources by allowing licensed channels to be opportunistically accessed by unlicensed users (cognitive radio devices) during periods of time when the license holder (primary user) is absent from its channel. Uncoordinated competition over limited resources among cognitive radio devices poses complex co-existence challenges. We propose novel bio-social inspired behavioral models and map out plausible evolutionary trajectories of co-use strategies in the cognitive radio ecosystem. By drawing parallels between …

Cuny Will Be Free!: Black, Puerto Rican, And Women’S Compositions, Literatures, And Studies At The City College Of New York And In New York City, 1960–1980, Conor Tomás Reed

Dissertations, Theses, and Capstone Projects

In my dissertation, CUNY Will Be Free!: Black, Puerto Rican, and Women’s Compositions, Literatures, and Studies at the City College of New York and in New York City, 1960-1980, I argue that the writings, political actions, and relationships of City College students and teachers underwent a collective decolonial metamorphosis that transformed the landscapes of United States higher education, as public universities like the City University of New York and the University of Puerto Rico became key sites of counterinsurgency to suppress Third World coalitional projects. In doing so, I situate New York City as an epicenter of Black, Puerto …

The Interaction Of Attention And Memory On The Reorienting Negativity, John C. Moses

Dissertations, Theses, and Capstone Projects

The three-stage model of distraction asserts that when we are presented with salient but task-irrelevant information, our sensory systems first detect the distracting stimulus by way of sensory memory buffers, which is indicated electrophysiologically by the mismatch negativity (MMN). Following detection, attentional resources are involuntarily allocated towards the processing of the distraction, as represented by the P3a. Finally, attentional resources are shifted away from the distracting stimulus and returned to the task-relevant information, as indicated by the reorienting negativity (RON). A great deal of research has focused on this last step in the model, largely centering around defining the mechanisms …

Structure And Function Of Dopamine In The Inner Ear And Auditory Efferent System Of A Vocal Fish, Jonathan T. Perelmuter

Dissertations, Theses, and Capstone Projects

The neuromodulator dopamine is considered essential for coordinating the internal motivational state of an organism with appropriate behavioral responses to stimuli in the external environment. This could be accomplished by modifying the function of neural circuits involved in sensory processing such that they are “tuned in” and optimally sensitive to important stimuli during critical time windows. While dopamine modulation of auditory processing has been studied in the central nervous system, neuromodulation can also occur outside the brain, in the inner ear. The majority of investigations of dopamine in the ear are conducted using rodents and focus on its role in …

What Rome Really Adopted From Ancient Greece, Christian J. Vella

Dissertations, Theses, and Capstone Projects

The Roman conquest of the Greek city-states and the appropriation of many aspects of its culture, especially architecture and art, is well known. But what of the many great philosophies that began in the various city-states of Ancient Greece? This piece is made in attempt to answer this question. The scope of these sources will start with the beginning of the Western Philosophical Tradition, with Thales of Miletus and the Milesian, all the way up to, but not including, the foundation of the Christian Philosophical Tradition. After the year 146 BC if a philosopher is born in a Greek-City state, …

The Incorporated Hornist: Instruments, Embodiment, And The Performance Of Music, M. Elizabeth Fleming

Dissertations, Theses, and Capstone Projects

Roland Barthes famously described the “grain” as “the body in the voice as it sings, the hand as it writes, the limb as it performs.” Stated simply, this project asks What is the body in the horn as it sounds? Instrumentality is typically understood as extension and expression beyond the boundaries of the body; brass instrument musicking, however, begins not where the sound emerges from the bell, but at the very least at the meeting point of the player’s breath, the surfaces of the body, and the tube of the instrument. This project of instrumental incorporation understands music as a …

Sex, Scents, And Cephalopods: Factors That Affect Social And Reproductive Behavior In Chambered Nautilus And Oval Squid, Naomi J. Lewandowski

Dissertations, Theses, and Capstone Projects

Cephalopods are a highly specialized group of molluscs that show a wide range of behavioral patterns. Chambered nautilus (Nautilus pompilius) and oval squid (Sepioteuthis lessoniana) are two very distinct species of cephalopod that both provide unique insight into cephalopod reproductive and social behavior. In experiments utilizing both species, I aimed to fill in knowledge gaps in a range of reproductive behaviors from fundamental responses to conspecifics, to preferred mating habitat.

In Chapter 1 and 2 I tested individual nautiluses in a Y-maze where recipients were exposed to paired odors of two donor nautiluses. I collected data …

Developing A Dissociative Nanocontainer For Peptide Drug Delivery, Michael Patrick Kelly

Dissertations, Theses, and Capstone Projects

The potency and specificity of bioactive peptides have propelled these agents to the forefront of pharmacological research. However, delivery of peptides to their molecular target in cells is a major obstacle to their widespread application. A Trojan Horse strategy of packaging a bioactive peptide within a modified protein cage to protect it during transport, and releasing it at the target site, is a promising delivery method. Recent work has demonstrated that the viral capsid of the P22 bacteriophage can be loaded with an arbitrary, genetically-encoded peptide, and externally decorated with a cell-penetrating peptide, such as HIV-Tat, to translocate across in …

Innate Antibodies, Murine Models, And Evolution: A Study Of Trypanosome Lytic Factor Functions And Their Translational Applications, Joseph P. Verdi

Dissertations, Theses, and Capstone Projects

Trypanosome lytic factors (TLFs) are primate-specific antimicrobial protein complexes that lyse African trypanosome parasites by delivering the channel-forming toxin APOL1 to the invading microorganisms. Human serum contains two TLFs that are delivered to the parasite by separate mechanisms, only one of which has been characterized. TLF1 is endocytosed by a receptor that is typically blocked by other serum factors in vivo, suggesting that TLF2 is the more relevant lytic factor in the context of trypanosome immunity. TLF2 is non-covalently associated with polyclonal immunoglobulin M (IgM) antibodies, which we report here to be involved in the uptake mechanism. The TLF2-IgMs …

Analyzing Harmonic Polarities: A Tonal Narrative Approach, Stephen J. Whale

Dissertations, Theses, and Capstone Projects

This dissertation aims to develop an approach to analyzing common-practice repertoire based on the dynamic interplay of centripetal and centrifugal forces. It aims at interpreting various kinds of chromaticism and modulation in terms of the interaction of forces moving away from the tonic or principal key (centrifugal) and those returning to it (centripetal). Centripetal forces also correspond to the force of cadential substantiation of keys, not only the principal key, which I call temporal-centripetal force; temporal-centrifugal forces correspond to the phenomena of tonal instability, of motion through multiple regions.

The dynamic interplay and counterbalancing of these forces is a core …

Lead And Arsenic Contamination In Urban Soils In New York City, Anna Paltseva

Dissertations, Theses, and Capstone Projects

This dissertation examined total and bioaccessible soil lead (Pb) and arsenic (As) concentrations and their accumulation in commonly grown garden vegetables in New York City (NYC) metropolitan area. Direct oral ingestion of contaminated soil and consumption of plants that have accumulated Pb or As from underlying soil are known human exposure pathways in urban garden soils that often contain elevated levels of contaminants. The research had four components: (1) assessment of the variability of bioaccessible Pb in NYC urban soils; (2) field experiments to evaluate Pb stabilization and As mobilization by phosphate and alternative amendments; (3) development of a new …

Neurogenesis Is Altered Between And Across Brain Regions After Neurodegeneration And Injury, Alice Perez

Dissertations, Theses, and Capstone Projects

Adult neurogenesis is the addition of new neurons in the adult brain. In mammals, neurogenesis is largely restricted to the hippocampus and olfactory bulb, which underlie learning, memory, and olfaction. In songbirds, new neurons are incorporated into telencephalic regions that subserve the production, perception, and maintenance of song. Studies of the regulation of neurogenesis have exclusively focused on a single brain region and within a single hemisphere. Interestingly, it has yet to be investigated whether there are correlations between numbers of new neurons across regions and hemispheres within the same animal. Here we examined these differences in a rat model …

Assessment Of Third Wave Therapy Assumptions About The Relation Between Emotional Schemas And Psychoemotional Functioning, Emily Rachel Edwards

Dissertations, Theses, and Capstone Projects

Recent advancements in emotion theory propose that emotional schemas – individualized conceptualizations and beliefs about emotions – serve a fundamental function in guiding psychoemotional processes. These advancements have progressed alongside the development of third-wave therapies, which presume emotional schemas to be deeply involved in perpetuating psychological distress and emotional dysfunction. To critically assess the validity of this presumption, the current research proposed and evaluated an integrative model of psychoemotional functioning.

Two studies were completed using a combination of behavioral, performance-based, and self-report measures of emotional schemas and psychoemotional functioning. Though further research is needed, results suggest the integrated model of …

Towards A Pedagogy Of Life Purposes, Manny Lopez

Dissertations, Theses, and Capstone Projects

College students who understand how the courses that they are enrolled in connect with their broader life goals are more likely to apply an approach of task perseverance with academic endeavors. Yet, nearly three million adolescent community college students in the United States may not have developed clear purposes in life. Relatedly, overtime the lack of lucid life purposes contributes to maladaptive behavior.

This dissertation is a compilation of three interrelated studies that took place in two public community colleges in the City University of New York. Guided by authentic inquiry and framed by sociocultural theory, central to each study …

Heritage Speaker And Late Bilingual L2 Relative Clause Processing And Language Dominance Effects, Leeann S. Stevens

Dissertations, Theses, and Capstone Projects

Traditionally, heritage speakers are recognized as a heterogeneous group whose skills in their heritage language are unlike those of monolinguals or L2 learners of that language. Indeed, much evidence confirms the cognitive and linguistic uniqueness of this population. However, highly proficient heritage speakers may pattern more similarly to another bilingual population than typically assumed: first-generation late bilinguals.

The present study examines group-level processing differences between Spanish heritage speakers and Spanish-English late bilinguals in English, the second-learned and current societal majority language of these populations. Dominance is also analyzed as a possible effect of group processing differences, since traditionally and definitionally …

Words Are Found Responsible: Poetry's Jurisdiction And The Transformation Of Equal Rights, Talia Shalev

Dissertations, Theses, and Capstone Projects

Across various academic fields and from a range of political orientations, scholars note that a pervasive rights discourse shapes the imaginable horizons of identity, politics, and social life in the United States. Many critiques of rights since the 1970s highlight a particular conundrum of this rights culture: existing rights law and ubiquitous rights invocations fail to guarantee equal conditions for thriving across racialized and gendered axes of identity. Words Are Found Responsible: Poetry’s Jurisdiction and the Transformation of Equal Rights emphasizes and complicates elements of these critiques by reading poetry of the 1970s and 1980s in relation to shifting rights …

Clinical Characteristics And Neuroanatomical Predictors Of Acute Antidepressant Outcome For Patients With Comorbid Depression And Mild Cognitive Impairment, Jeffrey N. Motter

Dissertations, Theses, and Capstone Projects

Background: Older adults presenting with both a depressive disorder (DEP) and cognitive impairment (CI) represent a unique, understudied population. The classification of cognitive impairment severity continues to be debated though it has recently been subtyped into late (LMCI) versus early (EMCI) stages. Previous studies have found associations between treatment outcome and both cortical thickness and white matter hyperintensities (WMH), though report inconsistent directionality and affected regions. In this study, we examined baseline clinical characteristics and neuroanatomical features as prognostic indicators for older adults with comorbid DEP and CI participating in an open antidepressant trial. EMCI is hypothesized to have greater …

Exploration Of The Inhibitory Properties Of The Nucleoside Antibiotic Salicyl-Ams And Analogues Targeting Siderophore Biosynthesis In Mycobacterium Tuberculosis, Glennon Bythrow

Dissertations, Theses, and Capstone Projects

Mycobacterium tuberculosis (Mtb) is a resilient, obligate bacterial pathogen responsible for pulmonary tuberculosis disease (TB), that has upheld a significant impact on global public health throughout history. The World Health Organization (WHO) approximates nearly 10 million new TB cases arose in 2017 alone, accounting for 1.6 million deaths. There has been a notable rise in TB cases produced by multidrug‑resistant (MDR) and extensively drug-resistant (XDR) strains of Mtb. This, along with the intrinsic resistance of Mtb to many standard drugs and poor patient compliance, is deeply impacting global control of TB. Among the several strategies currently in …

Being Together: Imaginaries Of Coexistence And Resistance In Contemporary South Asian Writings, Mahendran Thiruvarangan

Dissertations, Theses, and Capstone Projects

Being Together is a critical inquiry into selected writings that produce a counter-hegemonic imagination of pluralism, coexistence and cultural resistance to the violence, dispossession and exclusions perpetuated by nationalist, racist and neoliberal forces in South Asian and South Asian diasporic contexts, primarily spaces within or associated with Sri Lanka. Due to the historical role the nation, homelands, native culture, sovereignty, and self-determination have played in liberating South Asia from the clutches of British colonialism in the mid-twentieth century, these ideas have enormous political valence to the socio-political lives of the communities that consider the region their homeland today. While this …

Diet, Inflammation, Gut Microbiome, And Mental Health, Ashley R. Polokowski

Dissertations, Theses, and Capstone Projects

Omega-3 fatty acids (ω-3 FAs) are an essential fatty acid necessary for healthy development in mammals. They possess anti-inflammatory properties and have more recently been shown to impact gut microbiota, both factors hypothesized to be associated with depression and anxiety. Thus, empirical efforts have begun to examine the benefit of ω-3 FAs as a treatment option for various psychological disorders. Although there is evidence that ω-3 FAs have favorable outcomes on depressive symptoms, the relationship between ω-3 FAs and anxiety and the pathways by which ω-3 FAs produce beneficial health effects are poorly understood. Both inflammation and the gut microbiome …

Sedimenting Territory: A Political Geology Of Oil, Earth, And Spatial Politics In Turkey, Zeynep Oguz

Dissertations, Theses, and Capstone Projects

Building on the recent turn to the material and earthly aspects of resources and political power in environmental anthropology and political geography, this work historically and ethnographically examines the kinds of territorial politics that oil’s materiality, geological qualities, and infrastructures have generated in Turkey. Despite being surrounded by oil-rich neighbors in the Middle East, Turkey’s domestic oil reserves supply only 7 percent of the country’s oil, all of which has been drilled in the Kurdish provinces of Batman, Diyarbakır, and Adıyaman in Turkey’s southeast, where the PKK (Kurdistan Workers’ Party) has been fighting the Turkish state since 1984 for cultural …
