Hydrodynamics Of Drops And Particles Driven By Marangoni And Diffusiophoretic Forces, Subramaniam Chembai Ganesh

Dissertations and Theses

This study investigates the hydrodynamics of particles and drops driven by forces generated by an asymmetrical physical and chemical surrounding environment. In the first part, a novel colloidal motor design driven by surface tension forces is proposed, utilizing an active Janus particle encapsulated in an immiscible liquid drop to form a compound drop/particle. Marangoni forces induced by asymmetric solute adsorption at the liquid-liquid interface of the drop propels the compound system. The propulsion speeds of the motor are analyzed for various relative sizes and configurations of the Janus particle and the encapsulating drop and the effects of varying the transport …

Hyperspectral And Polarimetric Imaging Of The Ocean For The Characterization Of The Surface Effects And Measurement Uncertainties, Mateusz Malinowski

Dissertations and Theses

Ocean and coastal waters are monitored by Ocean Color satellite sensors to determine concentrations of chlorophyll and water properties and identify areas of algal blooms and other events. The light radiance from the ocean is weak in comparison with the sky radiance, which requires very accurate atmospheric correction of the radiance measured at the top of the atmosphere (TOA) on the satellite and heavy validation of the derived water leaving radiance by field measurements from the ships and ocean platforms. For TOA and especially above water radiance the skylight reflected from the ocean surface represents one of the main sources …

Dissertations and Theses

This thesis offers a comprehensive analysis of the trajectory of U.S. foreign policy in Afghanistan spanning multiple administrations from Obama to Biden, contextualizing it within broader shifts in American interventionism since the Cold War. An examination of the Obama, Trump, and Biden eras, delineates the complexities of military interventions, nation-building endeavors, the limitations of incrementalism in addressing the multifaceted challenges of conflict resolution, and the challenges of maintaining stability in conflict regions while avoiding prolonged military engagements. Ultimately, it advocates for a comprehensive and more flexible approach to foreign policy, balancing idealistic aspirations with pragmatic considerations to safeguard national interests, …

Parasympathethic Nervous Activity And Social Exclusion In Borderline Personality Disorder, Rebecca E. Barnes

Dissertations and Theses

Abstract

The experience of being excluded is universally unpleasant. However, for individuals that suffer from Borderline Personality Disorder (BPD), the experience of social exclusion, or ostracism can be unbearable (Bortolla, et al., 2019). While there is a significant amount of research on physiological reactivity in BPD, no studies adequately connect the parasympathetic nervous system (PNS) responses of people with BPD to social exclusion which is critical to understand as the inability of the PNS of individuals with BPD to adapt to stressors may be a contributing factor to the elevated rate of suicide and suicide attempts in this clinical population …

The Menstrual Cycle In Psychotherapy: Interventions, Therapist Engagement, And Blind Spots, Rozita Alaluf

Dissertations and Theses

There is a dearth of literature on psychotherapy and menstruation, except for the treatment and diagnosis of issues associated with premenstrual distress. This study aimed to bridge this gap by investigating the frequency and context of discussions about the menstrual cycle, the factors influencing therapists’ engagement with this topic, and the therapeutic approaches utilized to address the menstrual cycle within psychotherapy.

In phase 1, 118 psychotherapists from various theoretical backgrounds completed a survey on menstruation in clinical practice. The data was analyzed using descriptive statistics. In phase 2, semi-structured interviews were conducted with 7 psychotherapists, primarily identifying their theoretical orientation …

Identity-Focused Therapist Self-Disclosure In Matched Sexual/Gender Minority Dyads: A Longitudinal Therapy Process-Outcome Study, Brian Thomas Neff

Dissertations and Theses

Therapist self-disclosure (TSD) is a controversial clinical intervention whose benefits and drawbacks remain contested. Notably, no prior research has differentiated explicitly between self-disclosures related to the therapist’s core identities and those peripheral to identity, and qualitative studies suggest that identity-focused therapist self-disclosure (TSD-I) may be beneficial when therapist and patient share at least one marginalized identity. LGBTQ+ people, who experience significant health disparities and utilize psychotherapy more than their heterosexual and cisgender counterparts, could benefit particularly from TSD-I. The mental and physical health challenges facing LGBTQ+ individuals are predominantly explained through minority stress theory, which suggests that societal prejudice and …

Atm-/-Ung-/- Mice Present Reduced Levels Of Switched Immunoglobulin Isotypes Igg1 And Igg3, Lyric M. Haughton

Dissertations and Theses

B cells excise and recombine the immunoglobulin heavy chain gene locus during class switch recombination (CSR). CSR is mediated by activation induced cytidine deaminase (AID) and results in a new immunoglobulin isotype that B cells will secrete and present. AID produces mutations that convert cytosines to uracils within the intronic switch regions that precede and follow the target immunoglobulin isotype coding sequence. To resolve the mutations, B cells conduct either base excision repair (BER) or mismatch repair (MMR). Inactivating genetic mutations in BER or MMR reduce CSR. For example, a knock-out of uracil DNA glycosylase (UNG) causes a 50% reduction …

Dissertations and Theses

The current study examines the prevalence of and relationship between mental health outcomes (depressive symptoms, anxiety) and adverse childhood experiences (ACEs) among a sample of Southeast Asian Americans (age: M = 26.6, SD = 4.0) who self-identified as sexual and gender minorities (e.g., gay, lesbian, bisexual, nonbinary, transgender, queer/questioning, intersex, asexual and plus [LGBTQIA+]) (n = 41). Our national online survey was co-developed with a partnering community-based organization (CBO), Mekong NYC, and was disseminated through Southeast Asian American and/or LGBTQIA+ serving CBOs, university-affiliated organizations, and relevant affinity groups.

Results indicate that participants in our sample who identified as female, …

Comparing Perceptions Of Continued Presence Of The Deceased And Unidentified Sensed Presence Experiences In A Non-Clinical Sample Of Paranormal Experients, Scarlet Sidwell

Dissertations and Theses

Research on individuals' paranormal experiences, particularly sensed presence experiences, has predominantly focused on bereavement contexts (Kamp et al., 2020; Evrard et al., 2021). However, less is understood about the similarities and distinctions between perceived presence of the deceased and unfamiliar sensory perceptions of presence. The present study employs both quantitative and qualitative methods to explore the phenomenology of individuals' sensory experiences of presence within two distinct domains: perceptions of the continued presence of the deceased (PCPDs) and unidentified sensed presence experiences (USPEs). The current study utilized data from a sample of paranormal believers and experients to test the hypotheses that …

Belonging In The Psychic Nowhere: Racial Trauma, Racial Melancholia And Related Mental Health Outcomes Amongst South Asian Immigrants In The Us, Anusha M. Kumar

Dissertations and Theses

South Asian immigrants have experienced a nuanced immigration history in the US while straddling the Black-White racial binary. Despite their growing presence, research on South Asian mental health is relatively limited and often subsumed under the broader category of "Asian Americans," which obscures unique experiences due to the model minority myth and leads to a paucity of targeted studies, particularly in the U.S. Mental health outcomes, specifically depression, self-harm and disordered eating behaviors are prevalent within this community, and are exacerbated after large-scale sociopolitical events due to increased discrimination. Limited studies examine the intersection of racism and mental health outcomes …

The Role Of The Vibrio Cholerae Type Vi Secretion System During Kin Cell Interaction, Biofilm Formation And Priority Effects, Karen A. Castro

Dissertations and Theses

Vibrio cholerae’s Type VI secretion system (T6SS) is one of the arsenals used by the bacteria for its long-term survival in different environments, against a variety of opponents, and for its maintained pathogenicity in vulnerable regions of the world. Therefore, the more we understand about the activity of the T6SS, the closer we get to understanding its role in bacterial competition; inter-and-intra, and how this shapes a bacterial niche. Further, although the probiotic-like effect in the V. cholerae vaccine is described to work fast due to niche uptake hindering colonization of toxigenic strains, it is not yet clear if there …

Mentalized Affectivity And Its Role In Acculturative Adjustment And Well-Being, Bassem Barada

Dissertations and Theses

Immigration is a phenomenon that occurs on a global scale and continues to grow in prevalence to our present day. Therefore, acculturation remains an essential area of interest for the mental health field. Specifically, assessment of identification with either one’s ethnic culture or the dominant culture remains a robust way to capture acculturative adjustment (Chance, 2015). More recently, emotion regulation has emerged as an important construct in understanding wellbeing. Mentalized affectivity (MA) is an insight-based regulatory process that highlights the importance of understanding current emotional distress in the context of one’s past history (Jurist, 2005). The three dimensions of emotion …

The Romanticism Of The Patriarchy Versus Poems By Emily Dickinson, Anamelissa Carrion

Dissertations and Theses

Using poems by Emily Dickinson I will disect the closeting of the poet herself, meaning the hidden identity of the author from within her own work. The poems used here reference a writer hiding in plain sight, comparison to womens equality and how women have over centuries hidden their true identities in order to fit into the mandated social role of "feminine" as defined by men. The cyclical progression of womens rights movements.

This paper discusses how women will change their character and fundamental self development creating "closeted selves" or hidden selves they share to the world while hiding their …

A Study Of Gender Apartheid: Afghanistan And The Islamic Republic Of Iran, Golazin Safaeimojarad

Dissertations and Theses

This thesis investigates the systemic and institutionalized forms of gender-based discrimination termed gender apartheid, focusing on Afghanistan and the Islamic Republic of Iran. It argues that gender apartheid, a severe form of discrimination where women and girls are subjugated and denied fundamental rights under institutional frameworks, and Afghanistan under Taliban rule and Iran under the Islamic Republic of Iran are two prime cases of gender apartheid. Through a qualitative research approach employing case studies and a comprehensive review of legal documents, academic materials, and reports from reputable organizations, the thesis outlines how gender apartheid is not only a direct product …

Predatory Publishing And Global Scholarly Communications, Monica Berger

Publications and Research

redatory publishing is a complex problem that harms a broad array of stakeholders and concerns across the scholarly communications system. It shines a light on the inadequacies of scholarly assessment and related rewards systems, contributes to the marginalization of scholarship from less developed countries, and negatively impacts the acceptance of open access.   To fix what is broken in scholarly communications, academic librarians must act as both teachers and advocates and partner with other stakeholders who have the agency to change how scholarship is produced, assessed, and rewarded. Predatory Publishing and Global Scholarly Communications is a unique and comprehensive exploration of …

The Challenges Of Decoding Russian Coercion, Cynthia A. Roberts

Publications and Research

This review essay critically examines cultural explanations of deterrence and coercion, focusing on Dmitry Adamsky’s The Russian Way of Deterrence as the most important recent effort to explain Russian strategic behavior through the lens of strategic culture. While recognizing the book’s considerable strengths in describing Russian concepts, terminology, and practices of deterrence and coercion, the essay questions how much explanatory leverage culture actually provides. It argues that cultural approaches risk over-complexifying the Russian case while under-specifying causal relationships, and asks why distinctive strategic cultures do not produce greater variation in coercive behavior and outcomes. The essay contrasts cultural interpretation with …

A Multidimensional Look Into Covid-19’S Reverberating Psychological Consequences, Talia Schulder

Dissertations and Theses

Introduction: The COVID-19 pandemic has exacerbated preexisting inequities in depression and anxiety symptoms, particularly for marginalized populations. Post-disaster mental health has often been investigated in both public health and clinical psychological literature, and the present dissertation integrates both disciplinary frameworks to understand the reverberating psychological consequences of the pandemic. Methods: Data were collected Winter 2022-2023, and the present analyses used descriptive statistics, correlations, and structural equation models to measure associations between variables of interest. Two separate SEMs were conducted with variables often used in public health literature. Specifically, these models assessed the indirect relationship between COVID-19-related financial and social stress …

Education And Religion In Shaping Support For Same-Sex Relations: Considering Differences Over Time And Across Geographical Areas, Amy Adamczyk, Ashely French

Publications and Research

Across the world, attitudes about same-sex relationships have become rapidly more supportive. While education is typically viewed as a liberalizing force, religious beliefs are often seen as restricting more tolerant perspectives and contributing to more conservative attitudes in general. Focusing on the United States this study examines the roles of religion and education, as individual and group properties, for understanding disapproval of same-sex relationships. Drawing on restricted information that makes it possible to identify where General Social Survey respondents lived, we find that graduating from college is associated with more support, but has less of an effect on Evangelicals and …

Structural And Magnetic Properties Of Molecular Beam Epitaxy (Mnsb2te4)X(Sb2te3)1−X Topological Materials With Exceedingly High Curie Temperature, Candice R. Forrester, Christophe Testelin, Kaushini Wickramasinghe, Ido Levy, Dominique Demaille, David Hrabovsky, Xiaxin Ding, Lisa Krusin-Elbaum, Gustavo Lopez, Maria C. Tamargo

Publications and Research

Tuning the properties of magnetic topological materials is of interest to realize exotic physical phenomena, new quantum phases and quasiparticles, and topological spintronic devices. However, current topological materials exhibit Curie temperature (T_C) values far below those needed for practical applications. In recent years, significant progress has been made to control and optimize T_C, particularly through defect-engineering of these structures. Most recently, we reported T_C values up to 80 K for (MnSb₂Te₄)_x(Sb₂Te₃)_1−x when 0.7 ≤ x ≤ 0.85 by controlling the composition x and the …

Time-Efficient Filtering Of Imaging Polarimetric Data By Checking Physical Realizability Of Experimental Mueller Matrices, Tatiana Novikova, Alexey Ovchinnikov, Gleb Pogudin, Jessica C. Ramella-Roman

Publications and Research

Motivation: Imaging Mueller polarimetry has already proved its potential for biomedicine, remote sensing, and metrology. The real-time applications of this modality require both video rate image acquisition and fast data post-processing algorithms. First, one must check the physical realizability of the experimental Mueller matrices in order to filter out non-physical data, i.e. to test the positive semi-definiteness of the 4 × 4 Hermitian coherency matrix calculated from the elements of corresponding Mueller matrix pixel-wise. For this purpose, we compared the execution time for the calculations of (i) eigenvalues, (ii) Cholesky decomposition, (iii) Sylvester’s criterion, and (iv) coefficients of the characteristic …

It’S About Time, Part Ii: Does Time Poverty Contribute To Inequitable College Outcomes By Gender And Race/Ethnicity?, Claire Wladis, Alyse C. Hachey, Katherine M. Conway

Publications and Research

Existing research demonstrates gender- and race/ethnicity-based inequities in college outcomes. Separately, recent research suggests a relationship between time poverty and college outcomes for student parents and online students. However, to date, no studies have empirically explored whether differential access to time as a resource for college may explain differential outcomes by gender or race/ethnicity. To address this, this study explored the relationship between time poverty, gender or race/ethnicity, and college outcomes at a large urban public university with two and four year campuses. Time poverty explained a significant proportion of differential outcomes (retention and credit accumulation) by gender and race/ethnicity. …

Grid Culture, Eliot Bates, Arseni Troitski

Publications and Research

In this essay, we provide our initial ethnographic research about lines, which at a superficial level can be considered a platform, but which is also synonymous with a community of 8800 users, and with 606k unique posts authored by these users that in aggregate constitute a discourse network (Aufschreibesysteme, see Kittler 1990). lines—as platform, community, and discourse network—is primarily designed to support the development, documentation and user-generated code efforts specific to a set of hardware synthesis-related objects (the two we will focus on are called Norns and Grid; we’ll discuss what they are and what they do through the subsequent …

Assembling Hyperpop: Genre Formation On Wikipedia, Eliot Bates, Sophie Delphis, Romulo Moraes, Julia Santoli

Publications and Research

In this article, we analyze how a music genre is reciprocally defined online, through the crowdsourced ‘facts’ of Wikipedia. What are the traditional implicit and explicit exclusionary practices in this sort of genre formation? And how can internet-specific sociabilities create new exclusionary practices in the process of defining music? By analyzing the edit history of Wikipedia’s ‘hyperpop’ page, we locate ongoing debates, controversies, and contestations that point to shaping forces around online genre formation. These potentially have a huge impact on how hyperpop is understood both inside and outside of the music community. In locating the most active editors of …
