The Asymptotic Dirichlet Problems On Manifolds With Unbounded Negative Curvature, Ran Ji

Dissertations, Theses, and Capstone Projects

Elton P. Hsu used probabilistic method to show that the asymptotic Dirichlet problem is uniquely solvable if the curvature satisfies the condition $-C e^{(2-\eta)r(x)} \leq K_M(x)\leq -1$ with $\eta>0$. We give an analytical proof of the same statement. In addition, using this new approach we are able to establish two boundary Harnack inequalities under the curvature condition $-C e^{(2/3-\eta)r(x)} \leq K_M(x)\leq -1$ with $\eta>0$. This implies that there is a natural homeomorphism between the Martin boundary and the geometric boundary of $M$. As far as we know, this is the first result of this kind under unbounded curvature …

Teaching Gaze Shifting In The Context Of Requesting And Joint Attention To Toddlers With Autism Spectrum Disorder, Ivana Krstovska-Guerrero

Dissertations, Theses, and Capstone Projects

Impairment in eye gaze, including gaze shifting (GS) and making eye contact in early social communication is severely impaired in children with Autism Spectrum Disorder (ASD). This study examined the effectiveness of prompting and reinforcement to teach GS in the context of responding to a request and initiating joint attention to four toddlers with ASD. Intervention lasted 3-9 weeks with all toddlers demonstrating GS to mastery across both contexts. Toddlers also showed generalization to a repertoire of social-communication behavior, including increases in smiling. Some improvements in symptoms of autism and overall functioning were observed. Results suggest a promising brief intervention …

I Didn't Consent To That: Secondary Analysis Of Discrimination Against Bdsm Identified Individuals, Larry Iannotti

Dissertations, Theses, and Capstone Projects

Sadomasochism (BDSM) sexual behavior is an understudied phenomenon within the social sciences generally, and social work in particular. While BESM sexuality encompasses a wide variety of activities a community of individuals interested in BDSM is identifiable and has coalesced around organized groups, events, political activism, and shared sexual interests. This community has experienced discrimination, violence, and harassment (DVH) as a result of social approbation and stigma associated with BDSM practices. The study examines results of a secondary analysis of data from the Survey of Violence & Discrimination against Sexual Minorities, conducted in 2008. Severity and frequency of various types …

Use Of An Interdependent Group Contingency To Improve Homework Completion, Homework Accuracy, And Achievement Of High School Students With Disabilities, Maria Carrino Kennedy

Dissertations, Theses, and Capstone Projects

Homework is a frequently utilized teaching strategy in elementary and secondary classrooms. The completion of homework has been shown to have a strong positive effect on students' academic achievement across content and ability levels. Moreover, research suggests a stronger positive relationship between homework and achievement at the upper grade levels. Numerous interventions, both at home and at school, have been employed to increase students' level of homework completion and/or accuracy. The present investigation employed a single-subject reversal design to examine the effectiveness of an interdependent group contingency, with randomized components, on the homework completion, homework accuracy, and the academic achievement …

The Relative Impact Of Identity On Lgbt Api Outness: A Quantitative Analysis, Jessica Lee

Dissertations, Theses, and Capstone Projects

In the United States, the intersecting relationship among race, sex, gender, and sexuality plays a significant role in one's identity development and socialization. Especially for lesbian, gay, bisexual, and transgender (LGBT) Asian Pacific Islander (API) individuals, such interplay presents a continuous task of processing and presenting different identities. Employing a national sample of over 500 LGBT API individuals and utilizing multivariate regression analysis, this thesis explores how LGBT API individuals' sexual and racial identities affect their decisions in coming out to family, friends, co-workers, and other community members. Findings indicate that the level of discomfort in racial/ethnic and/or LGBT community …

An Investigation Of Factors That Create And Mitigate Confirmation Bias In Judgments Of Handwriting Evidence, Jeffrey Paul Kukucka

Dissertations, Theses, and Capstone Projects

Over a century of basic cognitive and social psychological research shows that humans naturally seek out, perceive, and interpret evidence in ways that serve to validate their prevailing beliefs (i.e., confirmation bias; Nickerson, 1998). In criminal justice settings, a priori beliefs regarding the guilt or innocence of a suspect can likewise guide the collection, interpretation, and appraisal of evidence in a self-verifying manner (i.e., forensic confirmation bias; Kassin, Dror, & Kukucka, 2013). Recently, confirmation bias has been implicated as a source of forensic science errors in wrongful conviction cases (e.g., National Academy of Sciences, 2009; Risinger, Saks, Rosenthal, & Thompson, …

Methods

The main data source was an existing matched dataset, constructed using administrative data from the New York City (NYC) Departments of Health and Mental Hygiene, Correction, and Homeless Services. The study cohort consisted of 15,620 NYC adults with recent histories of both jail incarceration and homelessness. Monthly experiences of jail incarceration, homelessness, and community-dwelling in 2001-03 were summarized into trajectory groups …

Essays On Non-Gaap Earnings Disclosure, Hangsoo Kyung

Dissertations, Theses, and Capstone Projects

Essay1: The U.S. Securities and Exchange Commission (SEC) issued new Compliance and Disclosure Interpretations (CDI) in 2010, relaxing enforcement of Regulation G and Regulation S-K. The nonbinding nature and opaque procedures behind interpretive guidance cast doubt as to whether SEC staff interpretations changed a firm's voluntary disclosure. In this paper, I find that firms more frequently disclose non-GAAP earnings after the issuance of new CDI, suggesting that nonbinding SEC staff interpretations influence corporate disclosure practice. Compared to the pre-CDI period, non-GAAP exclusions are of higher quality in the post-CDI period. The exclusion quality of firms who started to disclose non-GAAP …

Reading Nation In Translation: The Spectral Transnationality Of The Malaysian Racial Imaginary, Fiona Hsiao Yen Lee

Dissertations, Theses, and Capstone Projects

In recent decades, literary studies has experienced a global turn, often understood as a move beyond national paradigms of analysis, which are deemed to be narrow and particularistic. Although wary of the tacit universalizing tendencies of global frames, scholars of race and postcoloniality have critically embraced the global by arguing for the need to theorize transnationalism from marginalized perspectives. However, casting the global and the national in oppositional terms ignores the fact that national racial ideologies both actively shape and are shaped by globally circulating ideas about race. An understudied site in postcolonial studies, Malaysia--formerly known as Malaya--is an exemplary …

Aging Out Of The Spectrum Of Cultural Visibility, Darthea M. Miller

Dissertations, Theses, and Capstone Projects

I argue that the valorization of youth and the subsequent quest for agelessness has caused such an explosion of ageism that the elderly have been relegated to a culturally invisible status. The intersection of age and gender is doubly problematic for women due to sexism and the perennial objectification of the female body. Thinking of visibility as a measure of social acceptability, the consequences of cultural disappearance for the aging woman is an important site for investigation and theorizing. This thesis depicts the erasure of aging women from the cultural landscape as an effect of media representation and self-care work …

Initial Conditions In High-Energy Collisions, Elena Petreska

Dissertations, Theses, and Capstone Projects

This thesis is focused on the initial stages of high-energy collisions in the saturation regime. We start by extending the McLerran-Venugopalan distribution of color sources in the initial wave-function of nuclei in heavy-ion collisions. We derive a fourth-order operator in the action and discuss its relevance for the description of color charge distributions in protons in high-energy experiments. We calculate the dipole scattering amplitude in proton-proton collisions with the quartic action and find an agreement with experimental data. We also obtain a modification to the fluctuation parameter of the negative binomial distribution of particle multiplicities in proton-proton experiments. The result …

Rendering The Unthinkable: (Un)Knowable Animality, Compulsory Recovery, And Heterosexualized Trauma In The Hunger Games, Jennifer Polish

Dissertations, Theses, and Capstone Projects

Dystopian fiction is expected to reflect deeply on the interactions between identities, bodies, and state control. Suzanne Collins's The Hunger Games Trilogy is no exception. The disturbing trilogy situated animality, disability, and trauma (both of non-humans and of humans) as being firmly controlled by the power of the state (the Capitol). Through its portrayal of hunting and genetic manipulation, the trilogy constructed a state-created animality which refused definitive labeling and insisted upon facing animal subjectivity while simultaneously disregarding the needs and desires of those considered to be non-human. Similarly, the state held sway over both the creation and elimination of …

Hot And Bothered: The Role Of Arousal And Rejection Sensitivity In Dual Process Sexual Decision Making For Gay And Bisexual Men, H Jonathon Rendina

Dissertations, Theses, and Capstone Projects

Dual process theories of decision making acknowledge the functioning of two distinct yet simultaneous processes termed System 1 and System 2. While System 1 relies more heavily on automatic and affective processing, System 2 relies more heavily on effortful and cognitive processing. Over the past several decades, many lines of research have shown the importance of System 1 in decision making and several prominent social psychological theories of interpersonal behavior, such as rejection sensitivity, rely on this dual distinction between affective and cognitive processing. Despite the prominence of dual process theories in many areas of psychology, the role of System …

"She Said Plain, Burned Things": A Feminist Poetics Of The Unsayable In Twentieth Century Literary & Visual Culture, Leah Souffrant

Dissertations, Theses, and Capstone Projects

This dissertation examines the way silence, blank space, and other forms of creative withholding attempt to translate the unsayable, or to convey the unsayability of language in artistic form. Through a study of the works of Sylvia Plath, Jean Rhys, Rachel Zucker, Marguerite Duras, Anne Carson, and visual images, this work observes the connection between women's writing in the 20th century and the communication of painful subject matter through attention to absence. This study attends explicitly to how formal qualities in artistic works attend to ontological concerns through an examination of the intersection of concerns with phenomenology, feminism, and formal …

The Advance Of The Mobile Woman: Representations Of British Women's Physical Mobility, 1660-1820, Amanda Booth Springs

Dissertations, Theses, and Capstone Projects

Britain's long eighteenth century (1660-1820) underwent an infrastructure and transportation revolution. Over the same period of time, scholars argue, the ideology of "the domestic woman" grew increasingly prevalent. This dissertation explores the improvements to roadways and representations of the various ways in which British women of the period increasingly utilized transportation, equestrianism, and pedestrianism to traverse the nation, which was also reflected in the development of traveling clothing for women. It argues that these literary and pictorial representations depict the tensions around women's increasing capacity for physical movement, contending that the ideology of the domestic woman was largely reactionary rhetoric …

Committing To The Waves: Emerson's Moving Assignments, Karinne Keithley Syers

Dissertations, Theses, and Capstone Projects

Committing to the Waves: Emerson's Moving Assignments reads Ralph Waldo Emerson as a writer of assignments for living and working whose senses can be taken up across a wide array of creative and exploratory fields. Shifting between an interdisciplinary array of contexts ranging from philosophy and poetics to dance, performance, and somatic movement experiments, I join the practical sense of creative inquiry embodied in these fields to the abstract images of Emerson's assignments. I argue that Emerson's descriptions of intelligence and power, and so his approaches to navigating skepticism and loss, as well as the non-possessive sense of what "self" …

"For The Voices": The Letters Of John Wieners, Michael Seth Stewart

Dissertations, Theses, and Capstone Projects

American poet John Wieners is thoroughly disenfranchised from the modern poetic establishments because he is, to those institutions, practically illegible. He was a queer self-styled poete maudit in the fifties; a protege of political-historical poet Charles Olson who wrote audaciously personal verse; a lyric poet who eschewed the egoism of the confessional mode in order to pursue the Olsonian project of Projective (outward-looking) poetics; a Boston poet who was institutionalized at state hospitals. Wieners lived on the "other side" of Beacon Hill, not the Brahmin south slope, but the north side with its working-class apartments and underground gay bars. Though …

Gay And Lesbian Travel Writing: A Present In Need Of A Different Future, Michael Verdirame

Dissertations, Theses, and Capstone Projects

The first half of this thesis will detail the history of travel, as well as the primary reasons why people travel and why it is such a lucrative industry. This will be followed by an account of the history of travel writing, with a specific emphasis on the various types of avenues available to travel writers and the reasons why people feel compelled to write about their travels. The first half will then conclude with a content analysis of three current gay and lesbian travel publications available on different media platforms--Passport Magazine as an online magazine, Man About World as …

Blogging Through Motherhood: Free Labor, Femininity, And The (Re)Production Of Maternity, Kara Mary Van Cleaf

Dissertations, Theses, and Capstone Projects

Drawing from a thematic analysis of 47 North American mommy blogs over a 2-year period, I situate the genre in critical discussions of feminism, media, and labor, exploring both the technological and cultural shifts that turn mothers into cultural producers and that turn the experience of motherhood into a commodity. I situate the content of such blogs, or what gets said therein, within theories of media, gender, and labor. Examining the blogs within and against such academic discussions allows me to develop an intersectional analysis of feminism, media, and labor studies.

Guatemalan Spanish As Act Of Identity: An Analysis Of Language And Minor Literature Within Modern Maya Literary Production, Kenneth Yanes

Dissertations, Theses, and Capstone Projects

My study approaches the use of Guatemalan Spanish in modern Maya literary works through a theoretical framework drawn on theories of "purity" and mestizaje, the concept of minor literature, and "image" and ideology of language. I problematize the "major"/"minor" dichotomy of language based on a Eurocentric view of the dominance of national languages as the extremely diverse linguistic ecology of Latin American lends itself to the deterritorialization of hegemonic discourse, but without sustaining a neat categorization of language. Guatemalan Spanish is a heavily Maya-inflected interlanguage share by all Guatemalans. Mayan writers chose purposefully to counter the ladino ethnocentrism of the …

Corticospinal Integration In Healthy Humans, Amanda Asmar, Leandra Manfredini, Kerri Mclean, Christina Scannapieco

Dissertations, Theses, and Capstone Projects

Synchronized arrival of neuronal signals from the periphery and motor cortex has been associated with neuronal plasticity and motor learning. The main objective of this study was to examine neuronal interactions following excitation of descending motor axons from the primary motor cortex (M1) and spinal neuronal circuits via transcranial magnetic stimulation (TMS) and transcutaneous electric stimulation of the spine (tsESS) in 15 healthy humans while seated semiprone. TMS was delivered below or above the resting motor evoked potential (MEP) threshold, for the tibialis anterior (TA) muscle, while tsESS was delivered at the lowest stimulation intensity that evoked responses in most …

Discussion: The significant variability in findings on NAC otoprotective efficacy …

Cortical Modulation Of Spinal Reflexes In Healthy Humans, Caitlin Bedell, Joseph Capogrosso, Kristin Thomas, Charlotte Westmoreland

Dissertations, Theses, and Capstone Projects

Considerable evidence suggests that monosynaptic and polysynaptic spinal reflexes are prone to corticospinal inputs. The goal of this study was to establish the cortical modulation of monosynaptic and polysynaptic spinal reflexes in healthy humans. Cutaneomuscular responses were evoked following stimulation of the medial edge of the right foot with a 30 ms pulse train every 10 s via a bipolar electrode and recorded from the ipsilateral tibialis anterior (TA) muscle. Across subjects, medial edge foot stimulation was delivered at 1.2 to 1.5 times the response threshold. The soleus H-reflex was evoked and recorded via conventional methods. The effects of transcranial …

The Effect Of Tdcs On Cd-1 Mouse Behavior Post Induced Sensorimotor Cortex Injury, Michelle Gardella, Natalia Gozias, Kristina Laktionova, Tricia Roehrig

Dissertations, Theses, and Capstone Projects

The functional topography of the motor cortex has been shown to be modifiable by transcranial direct current stimulation (tDCS). tDCS works by directing electrical currents into the brain which induces alterations in neuroplastic cortical excitability. This experiment’s aim was to test the effect of tDCS on recovery of skilled locomotion, recovery of balance, and recovery of grip strength after bilateral electrolytic lesions to sensorimotor cortices in mice. Tests employed in this experiment included the ladder test, grip test, and a balance pole test. We were able to show that 4 days of tDCS post brain injury in mice produced improvements …

Motor Imagery And Action Observation As An Alternative Gait Training Intervention For The Elderly, Matthew F. Cirelli, Brian Fettner, Lindita Ismaili, Danielle Jordan

Dissertations, Theses, and Capstone Projects

Motor imagery (MI) is the mental representation of movement without any body movement. Action observation (AO) is a non-physical method of training, in which the learner observes the action of another individual. Eighteen subjects between ages 60-80 were randomly assigned to 3 training groups, the MI, AO and motor training groups. All subjects were assessed and measured with the Expanded Timed-Get Up and Go (TUG) test and Figure-8-Walk (F8W) test. All three groups yielded a significant improvement in difference in total TUG time (<0.05). When individual aspects of the TUG were considered, the sit to stand component improved in the MI and Motor groups. The results of this study suggest that MI and AO can improve cadence and have an effect mirroring that of motor practice. If utilized properly, MI and AO may be indicated as a rehabilitation intervention adjunct to gait training, and potentially decrease the risk of falls in the elderly population.

Benefit And Quality Of Life Improvement In Older Adult Cochlear Implant Recipients: A Review Of The Literature, Theresa Bartoldus

Dissertations, Theses, and Capstone Projects

The aging population is increasing rapidly, and in this group hearing loss is one of the most common disabilities. For those with severe to profound impairment, which occurs in approximately 10% of this population, conventional amplification often fails to provide adequate benefit. In these cases, a cochlear implant is indicated. The literature on cochlear implantation in older adults has shown that it offers significant speech perception and quality of life benefits to this population. However, it remains controversial despite ample research demonstrating these benefits, due to concerns about surgical complications and reduced benefit due to aging processes. Much literature also …

Otoscopic And Tympanometric Outcomes In Haitian Children, Ellen May

Dissertations, Theses, and Capstone Projects

Outer and middle ear pathologies are common and highly treatable conditions that affect children worldwide. While data on the prevalence of outer and middle ear disorders in children in North America and other developed countries is ample, such data in developing countries is oftentimes scarce. Determining the prevalence of outer and middle ear disorders is vital, as these types of disorders, if left untreated, can have medical, audiological, and educational implications. Both the identification and treatment of outer and middle ear pathologies are especially important in Haiti, a country that has a severe lack of medical resources, and is especially …

A Review Of Animal Studies For The Efficacy Of D-Methionine In Reducing Threshold Shifts And Affecting Biochemical Changes After Exposure To Noise, Alexandra Petraru

Dissertations, Theses, and Capstone Projects

Noise induced hearing loss (NIHL) is a major public health concern in the United States and worldwide. Certain individuals such as factory workers and military personnel are at greatest risk for irreversible sensorineural hearing loss due to the limitations of hearing protection measures and devices. D-Methionine (d-Met) is an antioxidant otoprotective agent that currently is in human clinical trials. The purpose of this systematic literature review was to review d-Met’s efficacy in reducing threshold shifts as well as in producing biochemical and physical changes in animal studies vis-à-vis the administration paradigm (preloading, rescue and a combined approach), d-Met dose quantity …

The Effects Of Morning Versus Evening Stretching Exercises In Hamstrings Flexibility Gains, Camron Einerman, Emily Eleff, Ana Ilijeska, Aliza Zinberg

Dissertations, Theses, and Capstone Projects

Many human physiological functions, including muscle flexibility, exhibit a pattern over a 24-hour period, known as circadian rhythm. Muscle flexibility and its circadian rhythm have been researched, though much more information is needed, especially regarding the hamstring muscle group. The object of this study was to determine if stretching at different times of the day results in differences in hamstring flexibility. Since muscles and joints are most flexible at night, greater ranges of motion should be available, allowing for a greater degree of stretching to take place. We hypothesize that when utilizing the optimal type, duration, and frequency of stretch, …
