Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson

Master's Theses

Bottlenose dolphins utilize acoustic signals as their primary mode of communication. Although some aspects of dolphin vocal behavior are well understood, less is known about vocalizations in different behavioral contexts and how these vocal behaviors may indicate habituation and sensitization. The focus of this study was to investigate how bottlenose dolphins respond vocally to a novel stimulus. Archival data from three populations of bottlenose dolphins (N = 20) living in a human-care facility were exposed to a novel apparatus (a mirror) for 10 trials, each lasting 20 minutes. Five of the trials presented the mirror covered with an opaque …

A Comparison Of Six Dif Detection Methods, Xueying Gao

Master's Theses

In the context of educational measurement, a test item is identified as differentially functioning across groups when the probability an examinee’s response to it depends on group membership. Methods for detecting uniform and nonuniform DIF have been studied and examined over decades to improve the validity of tests. The current study focused on examining and comparing the effectiveness of six DIF detection methods: the Mantel-Haenszel (MH) procedure, the Logistic Regression procedure, the multiple indicators multiple causes (MIMIC) model, the item response theory likelihood-ratio test (IRT-LR), Lord’s IRT-based Wald test and a Randomization Test based on a R-square change statistic. A …

Nutrition, Physical Activity, And Screen Time -Related Attitudes And Perceived Barriers Of Family Childcare Providers And Differences By Ethnicity, Qianxia Jiang

Master's Theses

Background:Childcare settings play an important role in shaping young children’s eating, physical activity (PA), and screen time (ST) behaviors. However, little research has focused on family childcare homes (FCCHs). This paper examines family child care provider (FCCP)-reported attitudes and perceived barriers related to nutrition, PA, and ST of preschool aged children in their FCCH, exploring differences by provider ethnicity.

Methods:We used baseline data from an ongoing cluster-randomized trial including surveys with FCCPs. We examined demographic characteristics and provider-reported nutrition, PA, and ST-related attitudes and barriers. Differences by ethnicity were assessed using chi square and multivariate loglinear analysis adjusting …

Differences In Mandibular Dentogingival Exposure As A Function Of Age And Type Of Facial Expression, Alison Loewenstein

Master's Theses

Statement of Problem:The need to accurately and reliably assess the maximum mandibular dentogingival display is essential during the planning of dental treatment, and inaccuracies in capturing a patient’s genuine border movements in the mandible can result in a faulty treatment outcome.

Purpose: Maximum smile as an expression is a frequently used to establish the extent of dentogingival display in the dental practice. In this study, the facial expressions “maximum smile,” (MS) “eyes closed smile,” (EC) and enunciation of the word “church” (CH) was used to evaluate the effect of facial expression on mandibular dentogingival display, and to assess the …

College Students' Disenfranchised Grief Following A Breakup: The Effect Of Relationship Closeness And Perceived Stigma On Grief, Jennifer E. Reimer

Master's Theses

Grief is a universal reaction to loss. Losses are often associated to the death of a loved one, however, they may also originate from the end of an intimate partner relationship. Whereas studies have focused on grief after a divorce or on symptomology students endure after a death, this article attends to the understudied college student experience of grief following a breakup. Within emerging adulthood, the loss of a close romantic relationship may be challenging to navigate alongside the daily stressors of college. Stigmatization by means of social cues convey sentiments, such as the need to get over an ex-partner, …

Observations Of The Copenhagen Networks Study, Michael A. Cantrell

Master's Theses

Attribute-rich longitudinal datasets of any kind are extremely rare. In 2012 and 2013, the SensibleDTU project created such a dataset using approximately 1,000 university students. Since then, a large number of studies have been performed using this dataset to ask various questions about social dynamics. This thesis delves into this dataset in an effort to explore previously unanswered questions. First, we define and identify social encounters in order to ask questions about face-to-face interaction networks. Next, we isolate students who send and receive disproportionately high numbers of phone calls and text messages to see how these groups compare to the …

Inventory Of Aging-Friendly Pedestrian Environment, Qijun Zeng

Master's Theses

The dimension of humanization has been neglected for decades. Planning themes such as automobile and transportation have erroneously occupied a dominant position. While public space, pedestrian activities and urban space as a gathering place for urban residents have been placed in a very minor position. As motorization in contemporary cities develops, the overall pedestrian environment of cities is deteriorating, and the street spaces are seriously lacking in the care and consideration of pedestrians, especially the vulnerable groups. Urban design generally, and pedestrian environment in particular, has a significant influence on pedestrian activity. Also, with the aging of the Baby Boomer …

The Proteomic Response Of Northern Elephant Seal (Mirounga Angustirostris) Pups To Physiological Stress During Development, Melissa P. Voisinet

Master's Theses

Background: Northern elephant seals transition from terrestrial nursing pups to pelagic foraging juveniles in a short period of just 8-12 weeks. During the post-weaning period, pups rely solely on the energy reserves gained during nursing for their caloric demands and water supply. The prolonged absence of food after weaning is the first of many fasts for which the seals have evolved adaptations such as decreased urine production and increased blubber reserves. The stressors experienced from learning to dive for the first time are also stressors that they will experience frequently as an adult and for which they have evolved adaptations. …

Evaluating Creative Choice In K-12 Computer Science Curriculum, Kirsten L. Mork

Master's Theses

Computer Science is an increasingly important topic in K-12 education. Ever since the "computing crisis" of the early 2000s, where enrollment in CS dropped by over half in a five year span, increasing research has gone into improving and broadening enrollment in CS courses. Research shows the importance of introducing CS at a young age and the need for more exposure for younger children and young adults alike in order to work towards equity in the field. While there are many reasons for disinterest in CS courses, studies found one reason young adults do not want to study CS is …

Murder And Machismo: Behind The Motivations Of Salvadoran Women Asylum Seekers, Victoria Colbert

Master's Theses

This thesis aims to draw connections between a culture of machismo, an ideological gender belief distinct to Latin America with heavy traces of patriarchy and misogyny, and the motivations of Salvadoran women seeking asylum in the United States. I develop these connections by first reviewing the literature on structural violence, the form of violence wherein the structure or social institution prevents certain demographics of people from meeting their basic needs and living their optimal lives (Galtung, 1969). I repeatedly use structural violence and its functions to parallel the operations of patriarchy and machismo to suggest that violence against women (VAW) …

Seizure Detection Using Teager-Kaiser Energy And A Channel Signal Quality Assessment Algorithm, Samuel Clary

Master's Theses

This study investigated the possibility of reducing the time required for accurate epileptic seizure detection through a retroactive analysis. Epilepsy is a neurological disorder affecting over 50 million individuals globally and is defined as a disorder which results in two seizures unprovoked by fever or medication. Diagnosis of epilepsy typically involves a monitored stay at an Epilepsy Monitoring Unit (EMU). The monitoring and diagnosis process ranges on average from $35,000 to $40,000 for a single stay, and the patient results from EMU are not instantly available to the patient. The collected electroencephalogram (EEG) must be analyzed by a trained EMU …

Food Systems Adverse Health Impacts On Latinx Immigrant Communities By Lisa Marquez, Lisa Marquez

Master's Theses

This thesis focuses on the adverse health impacts food systems have on Latinx immigrant communities. Marquez looks closely at emergency services programs using the food bank run by the Our Lady of the Pillar in Half Moon Bay, California, and interviewed five Latina immigrants from Mexico and Central America. While the food banks provided these families with fresh produce, the women expressed that it is substandard to the produce in their home countries. The interviews are supplemented with the analysis of three spoken word poems by youth who are second generation or whom have spent the majority of their lives …

Play Behavior And The Development Of Boldness And Caution In Juvenile Belding’S Ground Squirrels (Urocitellus Beldingi), Madelene Shehan

Master's Theses

The ubiquity of play among juvenile mammals suggests it provides adaptive benefits, potentially through influences on the development of temperament in young animals. Juvenile Belding’s ground squirrels (Urocitellus beldingi) must balance competing demands for boldness and caution imposed by the fundamental trade-off between their short active season and their vulnerability to predation. In this study, I evaluated whether play helps to facilitate the development of an appropriate balance between boldness and caution in juvenile U. beldingi.I observed the play behavior of juvenile U. beldingiand conducted flight-initiation distance tests to measure boldness-caution at the beginning and toward …

Temperature And Tempers: Heats Impact On Mood And Language, John Sutton

Master's Theses

Abstract: Temperatures above 20° Celsius have shown to adversely impact human behavior, leading to increased aggression and violence. Climate change will contribute to both the magnitude and severity of this pattern as temperatures continue their rise. Contributions to this field of research have only recently begun to analyze online behavior and language as a proxy for hedonic state, or well-being. From a development perspective this study is relevant since the poor tend to live in some of the warmest regions on earth, and would thus be disproportionately impacted by increased temperatures. We use several sources of data; U.S. based …

The Effect Of Disability Status On Parental Input: A Study From India, Susann Skjoldhorne

Master's Theses

Human capital has for a long time been an important factor in economic growth theory. Previous literature shows a strong connection between parental input and the level of human capital attained by a child. The investment in child health and education has a positive effect on building human capital. When resources are scarce the allocation of resources will affect the opportunities that a child is given to achieve their potential. Gender preferences, birth order, and disabilities could all be factors that explain how parents chose to allocate their resources. Previous studies show that the distribution of parental input based on …

The Impact Of Cleft Lip/Palate And Clp Surgical Intervention On The Social Integration Of Adolescents In India, Mustafa Zahid

Master's Theses

Cleft Lip/Palate, a congenital orofacial anomaly, carries an incidence rate of approximately 1 in every 1000 births. In addition to the stigma associated with the condition, the varying levels of cleft severity might result in lower life outcomes which could include lower cognitive ability, physical and psychological well-being, social and behavioral outcomes of adolescents. This paper focuses on the social integration element of life outcomes, which is composed of the social inclusion and prosocial behavior of the adolescent. Despite the affordability of restorative surgeries, patients in rural areas of Low and Middle-Income Countries (LMICs) such as India face accessibility and …

Economic Shocks And Personality Traits Of The Ultra-Poor, Shikhar Mehra

Master's Theses

Personality characteristics and non-cognitive skills are strong determinants of decision- making and economic outcomes. Personality is commonly believed to be stable, especially after age 30, though some evidence exists that changes in occupational or social roles, or exposure to family or health shocks, can change an individual’s personality traits in the medium or long term. Evidence on short-term impacts of shocks on personality, however, is lacking, as is evidence from rural and less educated populations. In this paper, we study the short-term effects of two kinds of shocks on personality traits among young adults from ultra-poor households in Uganda. In …

The Behavioral Determinants Of Well-Being In Sierra Leone, Madison Levine

Master's Theses

Ensuring the needs of individuals are met leads to a more prosperous economy. Healthy economic activity is dependent on a supported community of people. These people express different levels of happiness depending on where they come from and make behavioral choices every day influenced by their association with their community. Currently most subjective data have come from western educated industrialized rich and democratic (WEIRD) areas. These results are placed as generalizations across all other countries and are not giving an adequate representation of well-being for the population in non-WEIRD areas. Our study outlines an in-depth survey covering subjective well-being measurements …

Are Menstrual Cycles A Biological Determinant Of Well-Being Amongst Sierra Leonean Schoolchildren?, Ashwini Shridhar

Master's Theses

The influence of hormones and biology on behavior is a topic that is rife with controversy, especially when it comes to sexual hormones. There is even more murkiness when it comes to the topic of menstruation and knowledge about women’s menstrual cycles. Recent research on this topic have seen a link between the hormonal fluctuations during menstrual cycles and various behavioral implications on competition, cooperation, and risk behavior. This study tries to expand existing knowledge by examining whether there is a link between hormonal fluctuations during menstrual cycles and risk preferential behavior using economic experiments in the largely understudied context …

Mentoring Female Entrepreneurs: Revenue Analysis, Candy M. Moreno Garcia

Master's Theses

Throughout the world, significantly less women own businesses than their male counterparts. In addition, they tend to own businesses that are smaller, have less growth, are less profitable and have lower sales turnover than those of men. Supporting female entrepreneurs is crucial as they tend to spend more on the health of the household, nutrition and education. This paper uses a randomized controlled trial to determine the impact of a mentorship program between experienced female entrepreneurs and inexperienced entrepreneurs, specifically focusing on the impact to profits. I use data collected from three rounds of survey over the course of six …

Indigenous Women's Bodies: Primer Territorio De Defensa, Ana Gabriela Avalos Tizol

Master's Theses

The teen pregnancy “epidemic” in Guatemala is a focal point when international and national NGOs demand that the government protect the civil and political rights of girls. In accordance, the state created laws (legal age for marriage - Ordinance 13-2017), implemented penal codes (statutory rape - Article 173) and created Programa Vida (conditional cash transfer of Q. 1,500 - $200 every two months) to address this ‘epidemic.’ Yet, only sixty-one teen mothers were involved in the program by the first year in 2018, indicating its inaccessibility. This thesis proposes to challenge the dominant narrative on teenage pregnancies, which blames “Mayan …

Empowering Female Entrepreneurs Through Mentorship In Medellin, Colombia: Results From The Field, Theresa Solenski

Master's Theses

Utilizing the power of local knowledge and peer networking, this study attempts to quantify the impacts of mentorship among female micro-entrepreneurs in Medellin, Colombia on empowerment. Developing countries such as Colombia have disproportionately high rates of unprofitable micro-businesses, many of which are managed by women. Internal constraints, such as disempowerment, play a central role in perpetuating poverty. We implement a 6-month mentoring intervention by pairing 18 successful entrepreneurs with 52 disadvantaged female, micro-entrepreneurs in Medellin, Colombia to measure the additional benefit of localized knowledge to micro-borrowers. Using a process of random assignment, I measure the change in female empowerment, measured …

Eugenics In Education Policy And The Impact On African American Students, Ruth Jones

Master's Theses

Eugenics was defined as a science which used selective breeding as a mechanism to increase desirable traits in a population while restricting and eliminating undesirable traits. Eugenicists fell out of favor in the United States after the fall of Nazi Germany. Yet, eugenic ideas continued to prevail as they heavily influenced medical, social, and academic systems in the U.S. The country’s education system still carries the legacy of eugenicists who helped to build it. The purpose of this qualitative study is to identify eugenic ideas in federal, district and local school policy and determine their connection to the very local …

Breaking The Chains: Reversing The School-To-Prison Pipeline Through The Academic Experiences Of Formerly Incarcerated Black Males, Folasade Ogunbanwo

Master's Theses

This case study explores the academic experiences of formerly incarcerated Black males. The goal of the case study is to inform policymakers and critical race scholars who take interest in the prison-to-school pipeline and ultimately dismantle the school-to-prison pipeline. The historical impact of slavery has manifested into this vicious pipeline and the overrepresentation of Black males in the prison industrial complex. This case study is to demonstrate how the net is casted on those affected by the incarceration system and that break the cycle for themselves by pursuing an education to create an upward academic trajectory.

With the information gleaned from this research, the study evaluates the current programs and assesses a path forward. The assumption from …

Indigenization Of Genocide Healing: A Grounded Action Of Culturally And Contextually Relevant Educational And Psychosocial Strategies To Reduce Impacts Of Societal Toxic Stress In Rwanda Post-Genocide, Jean Pierre Ndagijimana

Master's Theses

Sixty percent of the current Rwandan population were born after the 1994 genocide against the Tutsi and those born since or who were young at the time of the genocide have remained among those affected most. Although Western trauma theorists and interventionists have played the role of experts in the genocide healing, the exclusion of the indigenous population’s experiences, knowledge, and wisdom has limited them from meeting local needs. The post-genocide situation raises various issues, genocide ideology, and increasing family homicides; however, locals do not want to seek counseling services, or run the risk of being labeled as mentally ill. …
