Citizenship As A Social Determinant Of Health: Healthcare Access And Utilization In The Wake Of The Public Charge Policy Change, Errol Pierre

Student Theses and Dissertations

Research shows that many non-medical factors, called social determinants of health, impact health outcomes. These social determinants include both socioeconomic factors, such as income and education, and public policies, such as laws and regulations affecting access to healthcare. This study proposes that citizenship status is also a social determinant of health and supports this proposition by examining the impact of citizenship status on healthcare access and utilization in New York. The study data consist of enrollments, disenrollments, and paid medical expenses incurred by patients enrolled in Medicaid or the Essential plan, both of which are government-sponsored health plans. In addition …

Development Of The Patient Propensity Indicator: Measuring And Predicting Antecedents Of Insights Into The Individual Management Of Healthcare, Julie Monroid

Student Theses and Dissertations

This research describes the development of the Patient Propensity Indicator (PPI), a reliable and valid measure, which is grounded in the rigorous conceptualization and operationalization of psychometric (ability, attitude, belief), health literacy, and learning preferences constructs and their effect on medication adherence. Adopting a well-established protocol for instrument development (DeVillis, 2017) the PPI’s multi-construct items were developed based on the findings from an extensive literature review both within and outside of healthcare.

An expert assessment of 130 items was conducted by a distinguished judging panel who provided validation of the constructs and item reduction (87). Refined constructs and items were …

The Influence Of Parole Case Characteristics And Construal Level On Parole Decisions And Perceived Humanness, Yi Sin Goh

Student Theses

Despite the low rate of discretionary parole release in New York, much is still unknown about the processes underpinning parole decisions. The present paper delves into how aggravating and mitigating parole case characteristics (e.g. institutional behavior) relate to parole decisions and the perceived humanness of parole applicants. The paper also examines how construal level can moderate the above relationships. Finally, a moderated mediation model outlining the pattern of these relationships is posited and tested. 122 New York residents were recruited online and randomly assigned to read either an abstractly or concretely construed transcript for an interview with a parole applicant. …

Challenges In Migrating Imperative Deep Learning Programs To Graph Execution: An Empirical Study, Tatiana Castro Vélez, Raffi Khatchadourian, Mehdi Bagherzadeh, Anita Raja

Publications and Research

Efficiency is essential to support responsiveness w.r.t. ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code that supports symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development tends to produce DL code that is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, less error-prone imperative DL frameworks encouraging eager execution have emerged at the expense of run-time performance. While hybrid approaches aim for the "best of both worlds," the challenges in applying them in the real world are largely unknown. We conduct a data-driven analysis of challenges—and resultant bugs—involved …

The Personal Papers Of American Sailors, 1890s–1940s, Annie E. Tummino

Publications and Research

Personal papers in the archives at Maritime College, State University of New York, document the lives of alumni from the school’s founding in 1874 through the early decades of the 20th century. Journals, diaries, memoirs, and reminiscences located in these collections provide evidence of what it was like to work on a ship, far from home, travelling to foreign lands. In this article, I explore first-hand accounts of maritime life by Van Horne Morris, my maternal grandfather and a 1938 graduate of the Massachusetts Nautical School (now known as Massachusetts Maritime Academy), and several alumni of the New York Nautical …

Treatment Of Gravitational Pulling Sensation In Patients With Mal De Debarquement Syndrome (Mdds): A Model-Based Approach, Sergei B. Yakushin, Theodore Raphan, Catherine Cho

Publications and Research

Perception of the spatial vertical is important for maintaining and stabilizing vertical posture during body motion. The velocity storage pathway of vestibulo-ocular reflex (VOR), which integrates vestibular, optokinetic, and proprioception in the vestibular nuclei vestibular-only (VO) neurons, has spatio-temporal properties that are defined by eigenvalues and eigenvectors of its system matrix. The yaw, pitch and roll eigenvectors are normally aligned with the spatial vertical and corresponding head axes. Misalignment of the roll eigenvector with the head axes was hypothesized to be an important contributor to the oscillating vertigo during MdDS. Based on this, a treatment protocol was developed using simultaneous …

Tailored Resonant Waveguide Gratings For Augmented Reality, Matt Markowitz, Michele Cotrufo, You Zhou, Karl Stensvad, Craig Schard, Adam C. Overvig, Andrea Alù

Advanced Science Research Center

We explore the use of tailored resonant waveguide gratings (RWG) embedded in a glass-like matrix as angularly tolerant tri-band reflection filters under oblique excitation. Through inverse design we optimize 1D grating structures to support multi-frequency narrow- band resonances in an otherwise transparent background, ideally suited for augmented reality applications. In particular, we show theoretically and experimentally that a single RWG can be tailored to provide reflection levels larger than 50% under p-polarized excitation at three distinct wavelengths of choice, over a narrow bandwidth and within a substantial angular range around 58° incidence, while simultaneously eliminating ghost reflections from the glass/air …

The Ideal Elizabethan Marriage (Or Naught): How Fletcher’S Comedy, The Tamer Tamed Serves As A Sequel, Homage And Riposte To Shakespeare’S The Taming Of The Shrew, Katherine Brillante

Student Theses

In this thesis, I take my cue from Emma Smith, who observes that John Fletcher’s The Woman’s Prize, or The Tamer Tamed is “a sequel, an homage, and a riposte to Shakespeare’s own Taming of the Shrew” (xii). While demonstrating Smith’s point, I also explore the ideology of marriage in Renaissance England, considering what it means to be a rebellious woman with respect to that institution. While, as Ann Jennalie Cook observes, “a play is not an exact replica of the customs of the time” (83), these two plays nevertheless illuminate the ways in which marriage customs during this …

Millennials In The Workplace: Recalling Critical Incidents Of Negative Feedback, Jocelyn C. Key

Student Theses and Dissertations

The Millennial generation has become one of the largest groups in the workplace and reports needing constant feedback from their supervisors. However, previous research has suggested that while Millennials desire feedback, they only want it to be positive. This research study examined the critical incidents of negative feedback that Millennials employees and supervisors recall receiving and giving. The study consisted of a qualitative survey with multiple-choice and open-ended questions. The sample comprised of 61 respondents who identified as a Millennial – born between 1981-2000 and between the ages of 22-41 – and full-time employees, the equivalent of 35 or more …

The Gun Control Paradox In The States: Evidence From National Polls, William A. Rose

Student Theses and Dissertations

The majority has supported gun control policies in the U.S. for decades, but these policies have stayed unimplemented. While much progress has been made on research of this “gun control paradox” at the federal level, determining whether this dynamic towards gun control persists amongst state governments has seen next to none. Previously, this was due to lack of polling data to estimate public opinion among state populations. However, today, new resources have become available that allow for reliable estimates to be made. This study uses the disaggregation of national polling data on gun control from the past decade to determine …

Increase In Postural Orthostatic Tachycardia Syndrome (Pots) After Covid-19 Infection, Nana Dufie Akowuah

Student Theses

A new severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), popularly known as COVID-19 has been associated with new-onsets of neurological and cardiovascular symptoms after infecting people. Postural Orthostatic Tachycardia Syndrome (POTS), a form of dysautonomia, can occur after a viral or bacterial infection. Some symptoms of POTS include dizziness, postural tachycardia, presyncope and orthostatic intolerance. There has been some evidence that has identified POT following COVID-19 in some patients. Commonly affected are female long haulers of child-bearing age sharing a strikingly similar demographic to most autoimmune disorders. The most dominant symptom of long haul POTS at this point may be palpitations/ …

Cell‑Controlled Dynamic Surfaces For Skeletal Stem Cell Growth And Differentiation, Hilary J. Anderson, Jugal Kishore Sahoo, Julia Wells, Sebastiaan Van Nuffel, Hala S. Dhowre, Richard O. C. Oreffo, Mischa Zelzer, Rein V. Ulijn, Matthew J. Dalby

Advanced Science Research Center

Skeletal stem cells (SSCs, or mesenchymal stromal cells typically referred to as mesenchymal stem cells from the bone marrow) are a dynamic progenitor population that can enter quiescence, self-renew or differentiate depending on regenerative demand and cues from their niche environment. However, ex vivo, in culture, they are grown typically on hard polystyrene surfaces, and this leads to rapid loss of the SSC phenotype. While materials are being developed that can control SSC growth and differentiation, very few examples of dynamic interfaces that reflect the plastic nature of the stem cells have, to date, been developed. Achieving such interfaces is …

Sex Trafficking And Mental Health Treatments, Maria A. Georgescu

Student Theses

Currently there is no agreement amongst professionals on a specific approach for providing for victims of sex trafficking. A two-part study was conducted in order to screen mental health professionals who have experience providing for victims of sex trafficking to participate in a semi-structured qualitative interview. Through a grounded theory approach, light is shed on what mental health providers experienced with providing for victims of sex trafficking find effective.

The main findings highlight how being forced into sex trafficking young (under 18) is impactful for the course of treatment according to 100 % (n=6) of participants, meeting the patient where …

Children’S Ability To Understand And Respond To Wh- Questions About The Mechanics Of Abuse, Kaileigh P. Conti

Student Theses

One type of forensically-relevant information that can be difficult to obtain is that pertaining to the “mechanics of abuse.” More specifically, information that includes the descriptions of body positioning and clothing placement. Generally, the recommended strategy for questioning children in legal and forensic settings is to use broad invitations (e.g., “Tell me everything that happened”) and wh- questions (e.g., who, what, where, when, why, how). However, when it comes to the mechanics of abuse, there is some conflicting evidence. Some research suggests open-ended wh- questions are best in cases where the mechanics are hard to describe (e.g., intermediate clothing placement) …

Femqorg Index, Nahee Kim

Theses and Dissertations

The project Femqorg Index began as I realized an endless number of chatbots and robots were released into this world as a spark of technology wrapped in a feminine persona, only to be disposed of after a short period. My imagination then extended to the thought that after they were disposed of, the entities along with their memories and advanced technology, would converge to create a network of their own. In this network, needs of the chatbots and robots were met through the exchange of strengths such as an advanced problem-solving ability, or a sturdy body that allowed unrestricted movement. …

Anamnesis: A Film About Forgetting, Neville Pullar Elder

Theses and Dissertations

In the film Anamnesis I bear witness to the injury and death of my childhood best friend Dominic, when I was 11. The film is a quest: A search for a visual memory that I have forgotten or perhaps, deliberately hidden from myself. Can remembering the events in their entirety and chronological order help me heal? Is searching for the lost memories nothing more than a smokescreen to avoid the steps I must take to deal/heal the trauma?

I communicate the relationship between the interplay of memory-making and sense-making and the reconstruction process that enables our past and present to …

Red-Collar Crime: The Field Re-Examined, Kortni Macdonald

Student Theses

Red-collar crime is an understudied phenomenon that occurs when white-collar crime turns into physical violence and/or death (also known as fraud-detection homicide). Frank S. Perri, coined the term red-collar crime following his study of 27 homicides that occurred at the same time as or before the deadly white-collar criminal occurrences. This study explores the generalizability and practicality of this definition as applied to a new set of cases. Using a case study analysis of six cases this study analyzed the behavioral characteristics of these offenders meeting Perri's definition; Characteristics such as entitlement, lack of empathy, power orientation, rationalizations, exploitations, and …

On Power’S Doorstep: Gays, Jews, And Liminal Complicity In Reproducing Masculine Domination, Andrew J. Shapiro

Publications and Research

This article explores the gender complexities of men caught between social power and powerlessness. Specifically, I consider the cases of Jewish men and gay men in the late modern West, two demographics with deep historic ties to both abjection and privilege. Such "in-between-ness” steers many, especially those who are white, cisgender, and/or otherwise privileged, toward what I term liminal complicity, a normative adaptation whereby men embrace manly ideals while disavowing femininity in themselves and others. I synthesize cultural, interactionist, and psychoanalytic literatures on stigma, boundaries, and gender practice to articulate liminal complicity as both an emotional retreat from stigmatization and …

The Screen To Desire, Joseph Parra

Theses and Dissertations

Joseph Parra reflects on our often embellished online personas and their effect on our desires. Through luscious 3-dimensional painting Parra translates the seductive desire of the hypermasculine male-presenting figure through glorification and criticality. The tactile painting also acts as a rebellion to accurately represent “real” life on the digital screen.
