Waves Of Binding: Neural Oscillations Of Visual, Auditory, And Lexical Integration, Hannah Morrow

Master's Theses

If our conceptual knowledge about concrete objects is represented (in part) across the brain regions that are active when those objects are perceived, how is information from those regions integrated, or “bound” into a coherent whole? One potential mechanism for binding is synchronized neuronal firing. In particular, high-frequencies (e.g., gamma) may support local interactions, while lower frequencies (e.g., theta) may support longer-range interactions. Previous work has implicated the role of gamma and theta in binding, but not testing both on the same paradigm with a condition intended to create more cortical distance. We recorded participants’ EEG while they were presented …

Social Factors Influencing Family Planning Knowledge, Attitudes, And Practices In The Ngäbe Population In Bocas Del Toro And The Comarca Ngäbe-Buglé, Panama, Carolina Vicens Cardona

Master's Theses

Introduction: According to Panama’s 2009 National Sexual and Reproductive Health Survey, only 19% of indigenous women in Panama use modern family planning (FP) methods. Despite the Ngäbe representing 62% of the indigenous population, there is limited research on their use of FP.

Methodology: 14 Ngäbe communities in Bocas del Toro were surveyed. Women between the ages of 18 and 50, and had >2 children completed a survey to assess knowledge, attitudes, and practices regarding family planning.

Results: A total of 148 women were enrolled, mean age was 32.18; mean number of pregnancies was 5. 32.4% of women …

Mir-433-3p Negatively Regulates Bone Formation And Targets Critical For Osteoblast Function, John Garcia

Master's Theses

Osteoblastic differentiation is tightly controlled by multiple signaling pathways associated with key transcription factors, as well as a number of microRNAs (miRNAs). miRNAs are small noncoding RNAs that function in the post-transcriptional regulation of gene expression. While clinical strategies to combat the reduction in bone density have often centered on impeding further bone resorption, this strategy neglects to promote bone formation, a component which is particularly problematic in the aging population. miRNAs could serve to bridge that gap, as potential therapeutic candidates. Several studies have established that miRNAs can direct osteoprogenitors towards an osteoblastic lineage through modulation of Wnt, MAPK, …

Exposure To Disability-Related Content And Attitudes Toward Persons With Disabilities Within The Uconn Mph Program: An Exploratory Study, Holly Labrecque

All students who reported having classes with students from other disciplines reported that it was valuable. Eighty-six percent indicated …

Clinical Assessment Of Repetitive And Restricted Behaviors In Toddlers On The Autism Spectrum, Katelynn Porto

Master's Theses

Repetitive and restricted behaviors (RRBs) are core symptoms of ASD and often emerge in the first year of life. It is important to understand how best to integrate diagnostically relevant information from multiple methods of assessment in clinical settings. The study aims to characterize the association between parent report and clinical observation of RRBs, compare the utility of each method for eliciting information on RRBs, and characterize the presentation of RRBs in toddlers at the time of initial diagnosis. Participants were 65 children ages 18-39 months diagnosed with ASD. Associations between a parent report rating scale, clinician-driven parent interview, and …

The Necessity Of Vesicle-Associated Membrane Protein Expression By Ng2 Glia For Maintenance Of Glial And Neuronal Health, Robert Horning

Master's Theses

NG2 glia are vital for the myelination of axons in the brain and spinal cord. Many NG2 cells receive synaptic inputs from neurons through neurotransmitters such as glutamate and GABA, but the consequences of this input have remained unclear. Interestingly, NG2 cells express voltage-dependent Ca²⁺ channels and transcripts encoding SNARE proteins that are necessary for vesicle docking in neurons. We therefore hypothesized that NG2 cells respond to neuronal synaptic inputs by releasing bioactive molecules in a Ca²⁺-dependent manner. To test this, we generated double transgenic mice in which a cre-inducible botulinum toxin (BoNT/B) is constitutively expressed by …

A Serial Multiplexed Approach To Immunolabeling Brain Tissue For Electron Microscopy, Peter Tiley

Master's Theses

To fully understand how biological systems give rise to complex phenomena, both structural and functional knowledge of the components in the system must be acquired. In this manuscript, I explain why new methods must be developed to achieve this level of understanding with brain tissue and introduce serial multiplexing as a potential solution. I discuss how this method can lead to highly annotated volume reconstructions of brain tissue using electron and light microscopy, along with the steps required to do so. I present what our lab has found throughout the process of adapting, refining, and combining more traditional methods together …

The Denial Of Black Victimhood: Examining Attitudes Of Sexual Assault And Victim-Blaming On A College Campus, A Continued Analysis, Odia Kane

Master's Theses

This study examines the attribution of guilt and victimhood in the context of rape on predominately white college campuses. The study is comprised of two samples; Sample 1 (n=362) and Sample 2 (n=1,144) of students from a New England university. Each participant read a vignette regarding two classmates: a female victim, Taneesha or Madeline, and a male perpetrator, Jamal or Connor, completing a group project. The findings of this study are critical because they analyze the surrounding attitudes of the treatment of victims of sexual assault and assess the social and political climate of rape culture on college campuses.

Sources And Fluxes Of Reactive N In A Southern New England River, Veronica Rollinson

Master's Theses

Little Narraganset Bay has seen an increase in filamentous algae, colloquially known as cladophora, over the past twenty years. The Pawcatuck River is the dominant input of freshwater to Little Narraganset bay, delineating the Connecticut and Rhode Island border. There are three point sources of nitrogen on the river system: two waste water treatment facilities (WWTF) in the estuary and one fabric processing plant within the upper-watershed in Kenyon, RI. Non-point sources include a myriad of farms specializing in turf and animal husbandry, as well as septic systems for the majority of the watershed that are not serviced by the …

Oral Health Literacy And Oral Health Practices In South Asian Populations, Ambika Sharma

Master's Theses

Background: Oral Health is a strong predictor of and has strong implications on overall health and quality of life. The 2018 Surgeon General’s Report of Oral Health declared a need for more data collection and surveillance on the oral health status of minority groups in America. Surveillance studies examining the scope of inequalities can ultimately drive policy to mitigate disparities. Surveillance data can also help shed light on South Asians in Americans, their oral health perspectives and practices.

Methods: A 19-question survey was administered to convenience samples of South Asians in Connecticut, New York and New Jersey. Study subjects were …

Innovation Dynamics Of Cultural Production: Evidence In Rap Lyrics, James M. Zumel Dumlao, Junjie Lei, Emeka Nwosu, Li Yu Oon, Tsai Ling Jeffrey Wong, James Rising, Jesse Anttila-Hughes

Master's Theses

Culture is a driving force in organizing the structure of societies, and is conjoined with economic development. However, quantifying the impact of culture is difficult. Culture manifests itself in cultural production, through art, performance, music, etc. Innovation and influence in cultural production industries partially determines product quality. Using techniques from the “digitized humanities”, we agnostically identify informational distance to describe the spatiotemporal dynamics of innovation and influence in Rap music lyrics. Rap emphasizes lyricism and hometown pride more than other genres of popular music, and is interesting as a globally impactful manifestation of the racially segregated labor market in the …

Stuttering And The Early Childhood Educator, Haley Jo Wesson

Master's Theses

The purpose of this research study was to gain information on early childhood educator’s knowledge of the myths and facts of stuttering. The researcher’s main question at hand is what are the effects of educator knowledge regarding fluency on young children? It was hypothesized that participants with a higher level of education will correctly identify more statements regarding stuttering than participants with a lower level of education. The researcher created a survey that was distributed to early childhood educators. The findings of the survey may be helpful in educating early childhood educators and bringing awareness to the misconceptions of stuttering.

The English Quarrel Of Crown And Mitre: Ecclesiastical Liberties From Thomas Becket To Thomas More, 1170-1535, Matthew Flanders

Master's Theses

Two rival sets of law, canon and common, warred for supremacy in England from 1170-1535. Just as with any battle, casualties followed. Where Becket and Henry II fought the first battle in this clash of legal systems, More and Henry VIII would end it. The deaths of Thomas Becket in the twelfth century and Thomas More in the sixteenth century bear a striking resemblance, but while this superficially indicates a consistency of outcome, it also probes further into a consistency of conditions which made such an outcome likely. The difference between common and canon law, and the feud born therein, …

Cascaded Linear Regulator With Positive Voltage Tracking Switching Regulator, Brandon K. Nghe

Master's Theses

This thesis presents the design, simulation, and hardware implementation of a proposed method for improving efficiency of voltage regulator. Typically, voltage regulator used for noise-sensitive and low-power applications involves the use of a linear regulator due to its high power-supply rejection ratio properties. However, the efficiency of a linear regulator depends heavily on the difference between its input voltage and output voltage. A larger voltage difference across the linear regulator results in higher losses. Therefore, reducing the voltage difference is the key in increasing regulator’s efficiency. In this thesis, a pre switching regulator stage with positive voltage tracking cascaded to …

Adverse Childhood Experiences: The Influence Of Poly-Victimization On Adolescent Delinquency And Adult Criminality, Samantha Qualkenbush

Master's Theses

Adverse childhood experiences (ACEs) are under-researched and a large part of unrecognized child victims. Although there is considerable research on trauma and adverse experiences in children, there are gaps in research concerning specific types of offending and specific ACEs. The purpose of this study is to determine if specific types of ACEs, or combinations of ACEs, influence children in differing ways related to adolescent delinquency and adult criminality. Analyses of previously collected data, specifically considering information on differences in the average number and likelihood of offenses for both juveniles and adults provides intriguing results. In concurrence with previous research, this …

Camagu: A Multimovement Work Exploring The Isixhosa Culture Of South Africa, Nkululeko Zungu

Master's Theses

The IsiXhosa language of South Africa is a rich historic language that has been preserved aurally through generations. The distinct clicks in this language, made in the mouth, are a characteristic spoken feature. Although IsiXhosa follows the Roman alphabet, individual letters require the pronunciation of different clicks, each having a different sound quality. These particular sounds will change depending on the interaction of the tongue and teeth within the mouth. Alongside this rich historic language is the practice of herbal healing, performed by individuals called Sangomas. A Sangoma’s primary goal is to communicate with the ancestors and to provide spiritual …

Does Population Density Affect The Singing Behavior Of Female Canyon Wrens (Catherpes Mexicanus)?, Lorraine Dargis

Master's Theses

Bird song has historically been considered from the perspective of temperate males despite females in many bird species being prolific singers. In this study, I investigated one species with female song, the canyon wren (Catherpes mexicanus). Canyon wrens do not duet like many other species with female song or other wrens. Instead, males and females sing sex-specific songs. The resource defense function of male canyon wren song is well-described, and males sing often during the breeding season. Females have only been observed to sing sporadically during the breeding season but sing reliably and often when exposed to playback of other …

At Hong Bang International University (HIU), teamwork training for nursing students at HIU has been applied but it has been difficult for all students to achieve high results and confidence in practicing teamwork skills. The effectiveness of self-study and group activities depends on many factors. The effectiveness of teaching approaches has not been measured and has needed to be addressed to result in the best learning experience for students. The results of this study provided recommendations to improve the quality of training as …

Effects Of Omega-3 Fatty Acids And Hypoxia On Progesterone Biosynthesis And Mitochondrial Morphology In The Corpus Luteum, Brian Krum

Master's Theses

The corpus luteum is a transient steroidogenic endocrine gland that forms from the remnants of the ovulatory follicle. This gland is responsible for the synthesis and secretion of the hormone progesterone, which is critical for the establishment and maintenance of pregnancy. In a non-pregnant cow, PGF2a is released from the uterus to regress the corpus luteum. However, in the case of pregnancy, the embryo must mitigate PGF2a synthesis to prevent corpus luteum regression. If the embryonic signal is either too late or too weak, uterine PGF2a secretion may result in corpus luteum regression and termination of pregnancy. Omega-3 fatty acids …

Cascaded Linear Regulator With Negative Voltage Tracking Switching Regulator, Ernest Lei

Master's Theses

DC-DC converters can be separated into two main groups: switching converters and linear regulators. Linear regulators such as Low Dropout Regulators (LDOs) are straightforward to implement and have a very stable output with low voltage ripple. However, the efficiency of an LDO can fluctuate greatly, as the power dissipation is a function of the device’s input and output. On the other hand, a switching regulator uses a switch to regulate energy levels. These types of regulators are more versatile when a larger change of voltage is needed, as efficiency is relatively stable across larger steps of voltages. However, switching regulators …

The Effect Of Music On Anxiety Of The Endoscopic Client In A Private Hospital In Ho Chi Minh City Vietnam, Hanh Thi Hong Nguyen

Master's Theses

Gastrointestinal tract cancer is one of the fifth most common cancers in Vietnam and has a high mortality rate in Vietnamese people based on the Centers for Disease Control and Prevention (2018) global cancer statistics. One-third of adults aged 50 or older, the age group at greatest risk of developing colorectal cancer, have not been screened because endoscopy is considered a stressful procedure. The endoscopic patient sometimes refuses to have the procedure. Therefore, using music to ease the anxiety of endoscopic clients has been examined in various studies but the results have been inconclusive. The aim of this study was …

Evaluation Of Patient Identification Practices By Nurses Working At Saigon Ent Hospital, My Thi Phuong Ngo

Master's Theses

Recently, patient misidentification has been identified as a common error in healthcare systems. Six patient safety recommendations from the World Health Organization (2007) have resulted in research and improvements to increase patient safety. However, patient misidentifications continue and are a challenge to patient safety. Failure to correctly identify patients continues to result in errors with medications, transfusions, diagnostic testing, and wrong person procedures. In the hospital, patient identification is performed throughout the hospitalization stay: at admission, before a treatment procedure or general nursing care, medication administration, and handover from provider to provider. In some hospital settings, this task is supported …

Significant Objects As Metaphor For Home, Alison Wilcox

Master's Theses

This qualitative Arts-Based Research investigated how certain objects come to embody a personal definition of home. Objects that are treasured and are associated with home were defined in this research as significant objects. As the researcher, I selected personally significant objects to study. These objects were studied through still life painting and interviews, based on the work of Barbara Fish (2017). Data were then refined into a final reflection painting. This study indicated that significant objects are often denied their intended function, are tied to idealized memories, and help to reconnect the owner to confidence that may have been lost …

Zebrafish Eye Development: Rac And The Creepy Crawlers Of The Eye, Zvi Murry

Master's Theses

During vertebrate eye development the optic vesicles protrude from either side of the brain and form the optic cups. As an optic cup starts to surround the lens a groove on the ventral side of the eye forms, known as the choroid fissure (CF). Normally, the CF will close around the optic nerve and hyaloid vasculature. If this process does not occur properly it results in a keyhole opening in the eye known as coloboma. This results in blindness and affects nearly 1 in 4-5,000 births. Zebrafish were utilized as a model for eye development to study CF closure (CFC) …

The Role Of Gibberellic Acid In Aphid-Plant-Arbuscular Mycorrhizal Fungus Interactions, Drew Olson

Master's Theses

Arbuscular mycorrhizal (AM) fungi form beneficial associations with the roots of most terrestrial plants, which is mostly characterized by increased plant nutrient acquisition (phosphate and nitrogen) by the fungi in exchange for carbon and lipids from the plants. These associations can also enhance plant coping mechanisms to abiotic and biotic stresses. However, insect herbivores, such as aphids, can benefit from AM fungi-plant symbioses by altering plant defenses that are driven mainly by the phytohormones jasmonic acid (JA) and salicylic acid (SA). Nevertheless, other phytohormones can modulate plant defenses by altering the balance of the JA and SA signaling pathways, such …

Online And Offline Identity Gaps: Cross-Contextual Predictors And Psychological Outcome, Ningyang Wang

Master's Theses

Using Communication Theory of Identity as a framework, this study compared an individual’s online and offline personal-enacted identity gap and examined the effect of each personal-enacted identity gap on individuals’ psychological well-being, as well as tested four cross-contextual predictors for online and offline personal-enacted identity gaps.

Survey data were collected from 214 participants on Amazon M-Turk. A sequence of hypotheses was tested. A questionnaire used for measuring individuals’ online personal-enacted identity gap was generated.

The result suggested individuals experience larger personal-enacted identity gap offline, which significantly negative predict individuals’ psychological well-being, whereas online personal-enacted identity gap positively predicts psychological well-being. …

Homotopy Analysis Method For Nonlinear Ordinary Eigenvalue Problems, Subagya Perera

Master's Theses

In this thesis, we solve nonlinear differential equations by the homotopy analysis method (HAM), which is a semi-analytic method first introduced by Shijun Liao in 1992. The modified HAM can be viewed as a more generalized method that encloses many perturbation and non-perturbation methods. It is different from perturbation or other analytical methods in that it allows considerable freedomformanyvariables. Using the modified HAM, especially zero-order and higher-order deformation equations, we solve a nonlinear initial value problem and a nonlinear eigenvalue problem. We adjust the convergence region of a solution by modifying auxiliary parameter values. The results converge in very few …
