A Biological Lens On Food Deserts [Biology], Claudette Davis

Open Educational Resources

SCB101 is a non-major biology course. In Fall 2022, the course was designated as an Experiential Learning-LaGuardia Humanitarian Initiative (LHI) course in CUNYFirst. LHI is LaGuardia's experiential learning program that helps students to critically reflect on global issues and develop sustainable solutions in partnership with local and global organizations. For the 2022-2023 academic year, LHI focused on two United Nations Sustainable Development Goals (UNSDG): Goal 2 and Goal 10. UNSDG 2 aims to end hunger, achieve food security, improve nutrition, and promote sustainable agriculture. UNSDG 10 addresses reducing inequality both within and among countries. Thus, I developed an assignment to …

Broadcasting La Presencia Latina: Tracing Identities Across Fields Of Interaction In Rural Minnesota, Anthony J. Harb

Dissertations, Theses, and Capstone Projects

This dissertation project traces the concerted efforts of an emergent Latinx immigrant community in Westplain, Minnesota to construct and assert their individual and collective identities within the public sphere through a range of multimodal and face-to-face communicative resources. I address enduring questions within the fields of linguistic anthropology, language education, and Latinx (media) studies through a multi-sited ethnography centered around three focal field sites: (1) a Spanish-language community radio program I call La Gran Comunidad Latina (LGCL); (2) a college-level civic engagement Spanish conversation course titled Noticias Comunitarias (NC) designed and taught in partnership with LGCL; and (3) an antiracist …

"How" As A Signal Of An Invariant Meaning, Andrew S. Mccormick

Dissertations, Theses, and Capstone Projects

This dissertation aims to explain why speakers and writers use how in the communicative contexts in which they do, and its central claim is that how is a signal of one invariant meaning. The form’s diverse communicative contributions can be explained by hypothesizing a single meaning that contributes to different message effects, or contextual interpretations, on different occasions of its use.

The present analysis rests on the crucial distinction in Columbia School (CS) linguistics, the theoretical framework guiding this project, between meaning and message. A meaning is a signal’s invariant semantic contribution, while messages are the context-unique interpretations that …

Navigating The Unprecedented: A Behavioral Theory Of The Firm's Perspective On Covid-19'S Impact On Workplace Practices, Jeffrey Augugliaro

Dissertations, Theses, and Capstone Projects

This study investigates the influence of COVID-19 induced uncertainty on the implementation and effectiveness of workplace practices, using the behavioral theory of the firm as the theoretical lens. Employing the Cube One framework as the set of practices to test, it hypothesizes that pandemic-induced uncertainty would reduce the frequency of management practices enacted, decrease variability across organizations, and diminish the relationship between enacted practices and organizational performance. Furthermore, the study posits that these relationships will be moderated by industry, given their variable levels of exposure to pandemic disruptions.

Contrary to expectations, the initial results revealed no overarching reduction or convergence …

Examining The Prevalence And Psychopathological Correlates Of Paraphilic Interests In A Non-Clinical Sample, Dylan H. Abrams

Dissertations, Theses, and Capstone Projects

The paraphilias are among the most contentious diagnoses in contemporary psychological discourse. One of the major debates is over the extent to which paraphilic interests and behaviors should be considered “deviant.” To address this issue, extant research has examined the prevalence of paraphilic interests and their correlation with psychopathology. Though findings suggest that certain paraphilic interests are relatively common, existing data may misrepresent true prevalence rates due to racially and ethnically homogenous sampling. Additionally, though an association between paraphilias and psychopathology has been found in forensic and clinical samples, this relation may not generalize to all individuals with paraphilic interests. …

Pre-Clinical Evaluation Of A Potential Ruthenium-Based Chemotherapeutic Agent For The Treatment Of Triple Negative Breast Cancer, Nazia Nayeem

Dissertations, Theses, and Capstone Projects

Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer that represents roughly 15% of all diagnosed breast cancers. TNBC is defined by the absence of expression of progesterone, estrogen, and human epidermal growth factor 2 receptors, and has a higher incidence rate in pre-menopausal women and women of African and of Hispanic ancestry. Due to the inability to target a receptor, treatment is limited to nonspecific chemotherapy or immunotherapy. Only one FDA approved therapy is available specifically to treat TNBC, which is antibody drug conjugate Sacitzumab-govitecan, given to patients who have already gone through two rounds of …

André Mocquereau's Theory Of Rhythm, Charles Weaver

Dissertations, Theses, and Capstone Projects

This dissertation examines the theory of rhythm developed by Dom André Mocquereau (1849–1930), a French Benedictine monk. Mocquereau’s theory was originally conceived as a method for performing Gregorian chant and has been the source for numerous publications and recordings since the beginning of the twentieth century. This dissertation places Mocquereau’s theory in the context of both the evolving performance practice of medieval monophony and the history of music theory in the nineteenth and twentieth centuries. Chapter 1 surveys the history of the notation of Gregorian chant, introducing the problem of constructing a rhythmic practice from historical sources. Chapter 2 examines …

Take Back The Power: The Fall And Rise And Fall Of New York City's Transport Workers Union Local 100, 1975–2009, Marc Kagan

Dissertations, Theses, and Capstone Projects

Take Back the Power: The Fall and Rise and Fall of Transport Workers Union Local 100, 1975-2009 tracks the history of this strategically significant union from the onset of New York City’s fiscal crisis in 1975 to the end, in 2009, of a second attempt to free transit workers from the grip of neoliberal economic austerity.

The first effort began in 1978 and culminated with the eleven-day 1980 transit strike, initiated by union dissidents over the opposition of the union president, but abruptly ended by him before a decisive victory could be won. That president, and his successors, reconciled themselves …

Uncertainties In Retrieval Of Remote Sensing Reflectance From Ocean Color Satellite Observations, Eder I. Herrera Estrella

Dissertations, Theses, and Capstone Projects

Ocean Color radiometry uses remote sensing to interpret ocean dynamics by retrieving remote sensing reflectance (������) from satellite imagery at different scales and over different time periods. ������ spectrum characterizes the ocean color that we observe, and from which we can discern concentrations of chlorophyll, organic and inorganic particles, and carbon fluxes in the ocean and atmosphere. ������ is derived from the total radiance at the top of the atmosphere (TOA). However, it only represents up to ten percent of the total signal. Hence, the retrieval of ������ from the total radiance at TOA involves the application of atmospheric correction …

Electrochemical Resistive-Pulse Sensing In Biological Systems, Rui Jia

Dissertations, Theses, and Capstone Projects

Electrochemical resistive-pulse (ERP) sensing with conductive carbon nanopipettes (CNPs) is a powerful technique for detecting single nanoscopic entities, such as single liposomes and biological vesicles, enabling qualitative and quantitative analysis of the redox molecules contained in such entities. ERP experiments were first carried out in biological system by inserting a conductive carbon nanopipette into a macrophage cell to sample single vesicles and measuring reactive oxygen and nitrogen species (ROS/RNS) contained inside them.

Besides sensing intracellular vesicles in macrophage cells, we applied this technique to direct detect single extracellular vesicles (EVs) released from a specific cell, and analysis of reactive oxygen …

Freedom Song: Uncovering A Politics Of Dignity In Black Feminist Thought And Praxis, Abegail M. Dobson

Dissertations, Theses, and Capstone Projects

This master's thesis delves into Intersectionality as an organizing framework and critical social theory, emphasizing the significance of Black feminist thought to social justice initiatives that challenge prevailing intersectional violence. The central inquiry of this project is uncovering a Black feminist conceptualization of dignity as articulated in foundational texts. I scrutinize the essence of dignity within Black feminist theory and praxis, particularly addressing the question: How valuable is a "right" when societal experiences consistently undermine one's basic needs and protections required to live a dignified life beyond survival?

Black feminist thought, encompassing praxis, is posited as a profound space for …

Tongues Out Of Place: Narratives Of Hereness And Images Of Be(Long)Ing, Christopher Hoffman

Dissertations, Theses, and Capstone Projects

What is the role of the psychologist during times of gentrification, climate change, and inequity? Using Hall & Massey’s (2010) term conjunctural crisis, or the overlapping of multiple disasters that bleed into each other, I argue that psychologists have a responsibility to combat social inequity and work towards tangible strategies in collaboration with communities to dismantle structures of oppression. In times of gentrification and climate change, I argue that psychologists must play a role in promoting public science, a praxis of research committed to applying social science with communities in order to work towards social justice and build a more …

Visualizing Dopamine Activity In Deletion Of D2 Receptors In Medium Spiny Neurons, Kunhee Lee

Dissertations, Theses, and Capstone Projects

Dopamine has been implicated in motivated behaviors and reinforcement learning. In this study, we are looking at the role of dopamine in allocating efforts when obtaining reward. Using Cre recombinase genetic tool, D2 receptors in striatal indirect pathway neurons were selectively deleted, and dopamine signal was recorded in ventral striatum using fiber photometry. Behaviorally, D2 receptor deletion resulted in less effort in a Progressive Ratio (PR) paradigm shown by decreased breakpoint, number of presses, and reward pellets earned. Due to the previous evidence that dopamine positively modulates effort, we hypothesized that there would be less dopamine release in D2 deleted …

Nonlinear Processes In Room Temperature Exciton-Polaritons, Prathmesh Deshmukh

Dissertations, Theses, and Capstone Projects

Strong light-matter coupling in solid state systems is an intriguing process that allows one to exploit the advantages of both light and matter. In this context, microcavities have become essential platforms for studying the strong coupling regime, where hybrid light-matter states known as exciton-polaritons form, leading to enhanced light matter interaction, modified material properties, and novel quantum phenomena. In this thesis, we explore the phenomenology of exciton-polaritons in strained TMD microcavities, 2D perovskites, fluorescent proteins and organic dyes encompassing thermalization, polariton lasing, and the observation of nonlinear effects.

Transition metal dichalcogenides (TMDs) have emerged as a remarkable class of two- …

Party Time: The Working Families Party And The Us Political System, 1998–2018, Luke P. Elliott-Negri

Dissertations, Theses, and Capstone Projects

In 1998, an upstart “third party” called the Working Families Party (WFP) limped onto the political scene in New York State. Ten years later, the WFP was at the center of the electoral effort that wrested control of the New York State Senate from the Republican Party for the first time in many decades, and a torrent of progressive legislation ensued. This dissertation is a history of the WFP from 1998 to 2018, when the Republicans were again—and this time stably—vanquished at the state level and socialists began to enter state and federal office in a new way. To develop …

Illness Intrusiveness And Psychosocial Adjustment Among Older Adults With Multimorbidity, Irina Mindlis

Dissertations, Theses, and Capstone Projects

Given the high prevalence of multimorbidity (MM) among older adults and the exponential growth of the older adult U.S. population, identifying factors that can lessen depressive symptoms and improve quality of life (QOL) in this population is timely and important. While it is well established that MM is associated with greater depressive symptoms and poorer QOL (Li et al., 2016; Makovski et al., 2019; Marengoni et al., 2011; Read et al., 2017), the mechanisms underlying these relationships remain understudied. The illness intrusiveness model (Devins et al., 1984) proposes that stressors posed by diseases (disease-related factors) and their treatments (treatment-related factors) …

Characterization Of Pathological Tau Mutants, Charles J. Mcdonald

Dissertations, Theses, and Capstone Projects

Tau is a protein expressed exclusively in glia and neurons in the central nervous system and implicated in several neurogenerative diseases called “tauopathies”. Among all the tauopathies, one third is characterized by the presence of genetic mutations leading to the synthesis of tau proteins with single amino acid substitutions at specific locations and affecting protein function. While most of the initial studies have emphasize the functional role of tau as modulator of the axonal cytoskeleton, it has recently been well accepted that tau is also an intrinsically disordered protein that tends to form membraneless organelles called coacervates, due to a …

Applying Structural Equation Modeling To Better Understand The Relationship Between Stressors, Social Support And Wellbeing In The Lives Of Spouse Dementia Caregivers, Craig Holden

Dissertations, Theses, and Capstone Projects

Applying Structural Equation Modeling to Better Understand the Relationship Between Stressors, Social Support and Wellbeing in the Lives of Spouse Dementia Caregivers considers the utility of Pearlin et al.’s (1990) stress process model in understanding the needs of spouse caregivers. Data were drawn from eight biennial waves of the University of Michigan Health and Retirement Study (HRS) and analyzed using structural equation modeling. The final study sample comprised 774 spouses, average age 73, who were categorized based on Alzheimer’s Disease and Related Dementia (ADRD) and non-ADRD caregiver status. Results showed that for the study sample as a whole, social support …

Extreme E-Service Learning: Remote Learning For Undergraduate Students And Telehealth Intervention For Children With Autism, Madiha S. Muzammal

Dissertations, Theses, and Capstone Projects

Extreme e-service learning courses in higher education, in which all components of the course including the instruction and service is provided online (Waldenr et al., 2012), offer rich educational experience as well as mutual benefits to the students, community and the higher education institutes. Very few studies have examined extreme e-service learning. We examined an undergraduate extreme e-service learning course in psychology; students learned through a virtual class and provided telehealth behavioral intervention services to children with Autism Spectrum Disorder (ASD). Utilizing mixed methods (quantitative and qualitative measures including student observations, assignments, and self-reports) and a mixed design (single subject …

Tunable Linear And Nonlinear Metasurfaces Based On Hybrid Gold-Graphene Plasmons, Matthew Feinstein

Dissertations, Theses, and Capstone Projects

Optical Metasurfaces are planar structures that are patterned with subwavelength structures and are very thin compared to the wavelength of light. Despite their thinness, these structured materials can strongly interact with incident light to effect the functionalities of conventional optical components, such as rotation of the polarization state, beam steering, lensing, spectral filtering, and holography, to name a few. Metasurfaces can also facilitate nonlinear optical effects, such as the mixing of beams at different frequencies to generate a beam at a new frequency.

The ability to alter the behavior of a metasurface during operation is highly desired for applications such …

Impact Of Sex In Luxury Fashion Advertisements On Brand Attractiveness And Identification, Alyssa Dana Dana Adomaitis, Diana Saiki, Juan Del Pozo Severino

Publications and Research

Purpose

This study examined perceived brand attractiveness of and identification with fashion luxury brands given different levels of sexuality in advertisements. Sex in advertisements has become increasingly more common to generate attention and interest in fashion luxury products, with limited research on its influence on the consumer. However, the use of sexuality in luxury advertisements may counter the ethical expectations of brands by the current consumer in the United States.

Design/methodology/approach

A sample of 1,266 males and females completed a survey on brand attractiveness and identification after examining an advertisement of a luxury fashion product. Participants were assigned an advertisement …

Weathering The Perfect Legal Storm: Novel Virus, Novel Instruction, Novel Course, Marissa Moran

Publications and Research

For this legal educator, in the spring and fall of 2020, three simultaneous and novel events-Corona virus, virtual synchronous instruction, and teaching a new interdisciplinary course for the first time, created an environment that could have resulted in the perfect legal storm. Instead, these events contributed to beneficial teaching and learning experiences from which arose many “first-ever” innovative faculty and student endeavors.

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

Examinations Of The Close Relationship Processes And Health Framework Among Adult And Adolescent Sexual Minority Men, Trey Victor Dellucci

Dissertations, Theses, and Capstone Projects

Despite advancements in biomedical preventions for HIV, sexual minority males continue to be disproportionately affected by HIV. Previous research has estimated that up to two thirds of HIV incidence among sexual minority male adults occur between main partners. In the past decade, a growing number of studies and intervention trials have focused on main relationships as a context for HIV. Much of this work has focused on adult relationships and has been grounded in interdependence theory and highlighted the importance of relationship functioning in facilitating the decisions couples make around condom use. Fewer studies, however, have examined the association between …

Sonorous Movement: Cellistic Corporealities In Works By Helmut Lachenmann, Simon Steen-Andersen, And Johan Svensson, John Popham

Dissertations, Theses, and Capstone Projects

In Sonorous Movement: Cellistic Corporealities in Works by Lachenmann, Steen-Andersen, and Svensson, I analyze three compositions that foreground the cellist-body, its physical gestures, and instrumental interactions: Helmut Lachemann’s Pression für einen Cellisten (1969/2010), Simon Steen-Andersen’s Study for String Instrument #3 (2011), and Johan Svensson’s marionette for string instrument, electro-mechanical devices and lights (2018). These works center sound production and the performing body as sites of ontological and creative exploration. Their physical gestures serve multiple sensorial functions, heightening the visual and kinesthetic dimensions of a traditionally aurally oriented practice. For each work, I develop a corresponding analytical method based on …

Colonial Investments: The Global Coordinates Of The English Political Imaginary, 1628–1668, Nathan D. Nikolic

Dissertations, Theses, and Capstone Projects

The main question my dissertation attempts to address is: what role did the expansion of English colonial trades play in the transformation of English society and government between the Petition of Right and the early years of the Restoration (1628-1668)? My thesis is that during this period, colonial expansion rose to the level of a general national interest and that many early seventeenth-century texts index the complexities and tensions of this development. As a small but very organized group of merchants, peers, and MPs mobilized the military and financial technologies of colonization to support Parliament’s war against Charles I, their …

Flamboyant Abundance: Performing Queer Maximalism, 1960–1990, Jack Owen Crawford

Dissertations, Theses, and Capstone Projects

This dissertation theorizes “queer maximalism” as an aesthetic of unmitigated flamboyance and voracious drag that appears in a constellation of performance-based artistic practices in the postwar United States. Queer maximalism brings together a historically grounded group of performers primarily based in New York City who have been variously described as theatrical, baroque, and Ridiculous and repositions them within an art-historical frame. Identifying drag and pastiche as central to queer maximalism, I show how artists salvage, assemble, and re-signify pop-cultural imagery, inflecting it with camp in order to fashion intimate community and openly flout societal norms of gender, race, and sexuality. …

A Study Of Geo-Regional Place-Consciousness In American Literature, Eugene Slepov

Dissertations, Theses, and Capstone Projects

The ancient Greek notions of topos, or place, and choros, or region, emerge from a an oral, narrative-based tradition that predates geography. These concepts remind us that that best source of material to study place is to be found in literary fiction. American fiction in particular will give us the evidence by which we can compile a qualitative, experiential understanding of the role of place in people’s lives. This dissertation inquires into the formation of the imaginative constructions that characters put upon place—such as through the process of consolidating and dwelling in places—and the way place puts …

You Don’T Even Need The Ghosts: A Writer’S Look At The Turn Of The Screw, Andrea M. Schenkel

Dissertations, Theses, and Capstone Projects

The novella Turn of the Screw by Henry James was first published in 1898 as a serialized novel in Collier's Magazine. The short novel is characterized by its concise language. James chooses words carefully and consciously. The linguistic compression forces the reader to deal intensively with the main protagonists of the novel: the Governess, the children, Miles and Flora, and Mrs. Grose. Nothing is as it seems. James aims to challenge the reader by forcing them to constantly question what they read.

Countless essays have been written about the text since the novel was published. The figures, especially those …

Ways Of Silence And Other Absences In The Music Of George Crumb, Jean-Patrick Besingrand

Dissertations, Theses, and Capstone Projects

The music of American composer George Crumb (1929-2022) is undeniably singular in the musical landscape. His aesthetic is often characterized by his exploration of timbre, his graphic scores, his use of quotation, his theatricality, and his interest in unusual instruments. This study proposes to take a different approach to Crumb’s aesthetic through the spectrum of silences and other absences. The concept of silence will be broken down and reconstructed through the Japanese concept of ma (間) and of empty spaces. Multiple types of silences and absences will be considered throughout this dissertation, expanding thus the concept of silence not only …
