The Role Of Language In The Media In Influencing Public Perceptions Of Refugees, Alison M. Pulliam

Senior Honors Theses

The refugee crisis has become a worldwide epidemic in recent years. As refugee entrance into host countries is debated, media outlets are covering the issue regularly. These media outlets use various types of language when portraying refugees. Many publications have been found to convey hostile and divisive themes as well as use specific linguistic tools, which contribute to negative portrayals of refugees. Media outlets have the potential to influence public perceptions of refugees because the general public in a host country receives its information primarily from the media. Overt and subtle language used to describe refugees has been previously found …

Improving Operator Situation Awareness By Phasor Measurement Unit (Pmu) Data Visualization, Esa M. Rantanen, Ernest Fokoue, Jacob Haut, Chandini Ramesh, Kathleen Gegner, Thomas Overbye, Komal Shetye

Articles

The application of phasor measurement unit (PMU) data in the power industry is currently an area of intense interest. The key driver for PMU technology is to use the precise time sources provided by Global Positioning System (GPS) satellites to accurately measure the relative voltage and current phase angles at buses across an interconnect at a very high sampling rate. Presenting PMU data to power system operators in a format that is truly useful for them and that affords improved situation awareness (SA) and fast and accurate decision making is a particular challenge to display design. This report describes development …

Systems Of Quantity Judgment In Various Species: A Meta-Analysis, Tiffany A. Woodard Baker

Dissertations

An abundance of behavioral and neuroimaging literature supports the presence of two cognitive systems for quantity judgments (Agrillo & Bisazza, 2014). In particular, small quantities are thought to be guided by the object-file system, a precise system that uses mental files to map onto real world objects, and large quantities by the approximate number system, an imprecise, estimation system (Dehaene, 1997). Evidence supporting both systems exists in a variety of species including nonhuman primates (Boysen & Hallberg, 2000), birds (Garland, Low, & Burns, 2012), amphibians (Uller, Jaeger, Guidry, & Martin, 2003), and fish (Agrillo, Dadda, Serena, Bisazza, 2009), but support …

Identifying The Social Contexts Present For Mouthing Behaviors In Bottlenose Dolphins (Tursiops Truncatus), Erin E. Frick

Dissertations

Much of the research on dolphin communication has focused on the acoustic signals produced in a variety of social contexts. Although acoustic signals are undoubtedly an important aspect of dolphin communication systems, dolphin communication is multifaceted and multimodal (e.g., postural, visual and tactile signals, acoustic cues). The present study examined behaviors that involve the mouth (i.e., mouthing behaviors) in a group of captive dolphins using 2,696 minutes of underwater acoustic and video recordings collected from 2010 – 2014. Target behaviors are described as primarily visual (e.g., open-mouth display), both visual and acoustic (e.g., jaw claps), and tactile (e.g., mouthing, biting). …

Pavlovian Conditioning: History And Application Of The Revaluation Procedure, Bana Odeh

Honors College Theses

While Pavlovian conditioning is a widely recognized form of learning, the nature of this learned association continues to be debated and has significant implications for human and animal behavior. This paper will first address the basic structure of Pavlovian conditioning as well as the two major historical hypotheses—Stimulus-Stimulus (S-S) learning and Stimulus-Response (SR) learning—regarding the underlying neural representation of first-order conditioning. Next, the revaluation procedure, an experimental method used to distinguish between these two hypotheses, will be discussed. Furthermore, the history of revaluation studies on rats will be analyzed, with an emphasis on the specificity of the learned association formed, …

Effort-Related Decision Making In Comt Variant Mice: Pharmacological Studies And Genetic Susceptibility To Motivational Dysfunction, Suzanne Cayer

Honors Scholar Theses

Effort-related decision making tasks in animals can model motivational symptoms in humans, which are a set of symptoms spanning a multitude of neuropsychiatric disorders, such as major depressive disorder and the negative symptoms of schizophrenia. The present studies aimed to evaluate the effort-related effects of the Val158Met polymorphism of human catechol-methyltransferase (COMT), by testing mice carrying either the human COMT Val (n=8) or Met allele (n=8) with Wild-Type control mice (n=15) by using concurrent FR2 and FR4/pellet choice tasks in a touchscreen operant conditioning apparatus. The Val158Met polymorphism has been repeatedly associated with neuropsychiatric disorders, and the Val allele has …

Ptsd And Dysfunctional Parenting: Emotional And Biological Mechanisms, Molly Franz

Department of Psychology: Dissertations, Theses, and Student Research

Women are disproportionately at risk for developing PTSD following exposure to trauma. Among its many harmful effects, PTSD is associated with a range of negative family outcomes, including impairments in parenting behaviors. Despite the prevalence of PTSD and its impact on parenting, little is known about the mechanisms responsible for this association. The present project addressed this gap by examining the impact of PTSD on dysfunctional parenting behaviors in a lab setting. Based on prior theory and empirical evidence, I expected that a diagnosis of PTSD would be associated with more dysfunctional parenting (i.e., harsh/overreactive and lax/permissive behaviors) during routine …

A Meat Paradox: Media's Role In Mitigating The Omnivore's Dilemma, Karyn Camille Lewis

Master's Theses

The purpose of this research is to identify and understand media’s role in meat consumption and a disassociation of meat and its animal of origin. This study questions consumer behavior based on media portrayals of meat products as well as how consumers perceive these portrayals, meat consumption patterns based on media and family influence, and the types and levels of satisfaction (ex: self-esteem or masculinity) consumers receive from meat products.

A quantitative research approach was proposed for this study. The primary research method was a survey among students, faculty and staff at The University of Southern Mississippi. A total of …

Facebook As A Social Outreach And Advocacy Tool In Intersex/Dsd Groups, Emelie J. Ali Ms

Publications and Research

My project includes a netnography of a Facebook intersex group called Families and Friends of Intersex People. I observed the group’s forms of communication within the group and which topics they discussed. It appears one of the major concerns the group has is the use of nonconsensual, sex assignment surgery on infants to “correct” their body to match a gender identity. I have also discovered a link between being intersex and affiliated with the LGBT+ community. Since the 20th century, intersex people have been stigmatized due to their assumed ability to engage in sexual, same-sex relations. I have concluded that …

Characterization Of Swine Production Using Measurements Collected Via Indoor Positioning System, Shaun Perisho

Dissertations

Legislative and market initiatives are requiring that gestating sows move from individual housing to group settings. Little information is known about coping styles of individual sows in these more socially complex environments and thus the impact of different behavioral strategies on sow reproductive success and efficiency was investigated. The movements of 70 sows during periods of reintroduction into large pen gestational housing following insemination was measured with a commercially available system that tracked animal location and accelerations. Principle component analysis (PCA) was used to establish composite variables characterizing each animal’s behavioral response to social reintroduction and revealed the presence of …

Personality In California Sea Lions (Zalophus Californianus) And Harbor Seals (Phoca Vitulina): Methodological Convergence And Species-Specific Emotional Repertoires, Amber De Vere

Dissertations

Despite the wide acceptance of animal personality as a valid area of study, research on marine mammal personality remains remarkably scarce. What literature does exist predominantly focuses on bottlenose dolphins (Frick, 2016; Highfill & Kuczaj, 2007; Kuczaj, Highfill & Byerly, 2012; Lilley, de Vere, Yeatre & Kuczaj, 2018; Moreno, Highfill & Kuczaj, 2017). There is also strong evidence for individual differences in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012), and preliminary research has provided evidence of broad personality factors in pinniped species using behavioral coding …

Effects Of Norharmane And Nicotine On The Conditioned Place Preference Of Mice, Lindsey Galbo

All NMU Master's Theses

Tobacco smoking in the United States is used by approximately 25% of adults. Many studies using animal models have suggested that nicotine has rewarding properties. Contrastingly, several studies have also found it to be a weakly reinforcing substance at low and high dose levels. Due to this, other tobacco constituents, such as the monoamine oxidase inhibitor norharmane which is found in tobacco leaf and smoke, may be responsible for tobacco addiction by potentiating the rewarding properties of nicotine. Several studies have attempted to observe this phenomenon, however, monoamine oxidase inhibitors that are not found in tobacco leaf or smoke have …

Discriminative Stimulus Effects Of Gabapentin, Michael Zuidema

All NMU Master's Theses

The present study sought to evaluate the discriminative stimulus effects of the anticonvulsant gabapentin in rats trained to discriminate 30.0 mg/kg gabapentin from vehicle in a two-lever drug discrimination task. All of the ten rats tested were able to establish gabapentin as an interoceptive cue. Gabapentin produced full generalization (≥ 80% gabapentin-lever responding) for itself at 30.0, 60.0, and 120.0 mg/kg doses. Pentobarbital produced full substitution, while pregabalin, carbamazepine, fentanyl, and buspirone produced partial substitution (≥ 60% gabapentin-lever responding) for gabapentin. Ethanol and raclopride did not substitute for gabapentin. The psychostimulant amphetamine did not produce substitution; however, the 0.25 mg/kg …

The Ush2a Gene: An Analysis Of Ultrasonic Vocalizations In A Mouse Model Of Usher Syndrome Type 2, Kiana R. Akhundzadeh

Honors Scholar Theses

Usher syndrome type 2 is a complex autosomal recessive genetic disorder that is characterized by moderate to severe congenital sensorineural hearing loss, the onset of retinitis pigmentosa in the second decade of life, and in some cases, vestibular dysfunction. Mutations in the USH2A gene account for 85% of cases of type 2. The USH2A gene is responsible for encoding the protein usherin, which has an important role in the development and function of inner ear hair cells and retinal photoreceptors. Until recently, it has been believed that carriers of the USH2A mutation were phenotype free. However, recent data has suggested …

The Conundrum Of Causal Reasoning In Elephants, Beri Brown

Master's Theses

Causal reasoning is marked by the ability to mentally reconstruct the missing part of a sequence in order to reproduce an outcome. While research on causal reasoning has been done with children, the results of the studies have been inconsistent. A standardized paradigm for comparative causal reasoning studies does not exist. Nissani (2006) investigated causal reasoning in a tool-use task with elephants and concluded that elephants were not capable of causal reasoning. The current study, a modified replication, yielded results that were not congruent with Nissani’s (2006) manuscript. Additionally, it was very unlikely that the Nissani (2006) study truly looked …

Mental Health And Teammates, Carly O'Dell

Honors Program: Senior Projects (Public)

Mental health is an aspect so essential throughout the human experience, yet an aspect overlooked by many. Specifically, mental health in youth is an area hardly touched by different initiatives, programs, and organizations that are put in place in order to bring assistance and guidance to youth. This is despite overwhelming statistics regarding youth and mental health. After analyzing the TeamMates Mentoring Program and finding inadequate measures in place regarding mental health, different initiatives were created in order to increase the program’s use of advocacy, awareness, and actions regarding mental health in youth.

Being In Performance: A Philosophical Account Of The Embodied Actor, Brad M. Krumholz

Dissertations, Theses, and Capstone Projects

In this dissertation I present and analyze three distinct actor-training exercises primarily through the lens of the Embodied Cognition (EC) branch of contemporary philosophy, which attempts to frame human understanding as a fully embodied interaction with the environment. Drawing from neuroscience, psychology, linguistics, and other branches of philosophy, EC provides both an excellent set of tools and a strong theoretical framework to help explain how people encounter meaning in life. I apply its unique perspectives to this philosophical account of the embodied actor as I analyze the various elements at play in actor training praxis, which allows me to shed …

Event-Related Potential Studies Of Error Monitoring To Affective And Non-Affective Stimuli In Adolescents And Emerging Adults, Rebecca K. Reed

Dissertations, Theses, and Capstone Projects

It is hypothesized that prefrontal cortex (PFC) and anterior cingulate cortex (ACC) function may be still under development in adolescents. As the generator of the error-related negativity (ERN) and the N2, the ACC is expected to be sensitive to the degree of development with age. In adults, these top-down control areas ideally serve to direct attention to goal-relevant information, which can increase the likelihood of making a correct choice, even in fast-response laboratory based tasks. However, adolescents may show increased susceptibility in these top-down control areas when the stimulus is social and emotional. In the first study, event-related potentials were …

Measuring Early Emergence Of Self-Awareness In Infants Using Eye Tracking, Melanie Lawrie

Theses, Dissertations and Culminating Projects

Recent attention has been paid to the neurological, evolutionary, and developmental correlates of human self-face recognition. In the present study, we examined 12-, 18-, and 24-month-olds using eye tracking to determine if there was a unique visual scan path of faces for self-recognizers as compared to non-recognizers. Results indicated that overall, 12- and 24-month-olds have different scan-paths compared to 18-month-olds. Eighteen-month-olds have an increased number of fixations and fixation time spent on the eyes, mouth and top half of the face, while 12- and 24 month-olds have more fixations on the nose and bottom half of the face. Furthermore, self-recognizers …

The Effect Of Napping On Sleep Quality And Quantity In Healthy And Concussed Collegiate Athletes, Katie Stephenson-Brown

Graduate Theses and Dissertations

Clinicians are increasingly prescribing a regulated sleep schedule to athletes post injury; however, baseline sleep habits of collegiate athletes are unknown. Moreover, the connection between napping and sleep quality and quantity has not been studied in collegiate athletes. Therefore, the purpose of this study is to investigate napping behaviors and their effects on sleep quantity and quality in concussed and non-concussed collegiate athletes. In a sample of 233 non-concussed collegiate athletes, 74% (172/233) of participants reported napping. Napping was not significantly associated with sleep quantity (χ 2 (2) = .23, p = .64) or quality (χ 2 (1) = .42, …

Depression is a serious illness that affects a large portion of the world’s population. Given the large effect it has on society, it is evident that depression is a serious health issue. This thesis evaluates, at length, how technology may aid in assessing depression. We present an in-depth investigation of features and fusion techniques for depression detection systems. We also present OpenMM: a novel tool for multimodal feature extraction. Lastly, we present novel techniques for multimodal fusion. The contributions of this work add considerably to our knowledge of depression detection systems and have the potential to improve future systems by …

Absences And Epistemologies Of Ignorance: A Critical Multi-Sited Study On The Teaching Of The Danish Colonial And Slave Trading Past, Naja B. Hougaard

Dissertations, Theses, and Capstone Projects

The present study is a critical investigation of the production of subjectivities through the teaching of the history of the Danish slave trade within the current neoliberal multicultural (Melamed, 2006) landscape of education. By conducting a study of teaching on this subject in the context of a Danish high school, the aim is to understand how the teaching-learning of the Danish slave trading history shapes the ground for Danish high school students to develop their own positionings with regards to the past as it ties into present day issues of nationalism and xenophobia in Denmark. Drawing on the concept of …

Nature Versus Nurture, Matilda Nikehasani

Dissertations, Theses, and Capstone Projects

The purpose of this paper is to expose the differences and similarities between nature and nurture. How they correlate to each other, and shape human development. Without nature and nurture, we would all be the same, and have the same experiences. This controversial topic is one of the oldest arguments in psychology

Socialization And Problem-Solving In Domestic Cats (Felis Catus), Mary Howard

Masters Theses and Doctoral Dissertations

There is evidence that an animal’s socialization towards humans and rearing environment can enhance their problem-solving ability. According to the social intelligence hypothesis, which states that intelligence evolved due to complex social environments, an animal’s social life should result in higher cognitive abilities. Domestic cats are capable of leading both solitary and social lives in their natural habitat, as well as in captive environments. I assessed both general problem-solving ability and the relationship between socialization and problem-solving ability, problem-solving speed, and latency to approach a novel apparatus in domestic cats. Twenty-four out of eighty-six cats solved the problem-solving task. There …

Personality And Affiliation Involving A Cooperative Task In Bottlenose Dolphin (Tursiops Truncatus) Dyads, Kimberly Bagley

Masters Theses and Doctoral Dissertations

Cooperation may be related to personality in bottlenose dolphin (Tursiops truncatus) dyads. Five bottlenose dolphin pairs at the Roatan Institute for Marine Sciences (RIMS), Honduras, were presented with an apparatus released a food reward if opened cooperatively. I created personality profiles of each dolphin with traits grouped in two different contexts: dolphin-dolphin and dolphin-world. I hypothesized that success of the cooperative task would be related to similarities in socialization and dissimilar in interacting with objects. None of the dolphin pairs cooperated to open the apparatus. I then analyzed individual personalities in relation to the dolphins’ individual and mutual interactions with …

Association Between Toxoplasma Gondii Seropositivity And Memory Function In Non-Demented Older Adults, Cynthia Elizabeth Wyman, Shawn D. Gale, Ariana Hedges-Muncy, Lance D. Erickson, Eric Wilson, Dawson W. Hedges

Faculty Publications

Toxoplasma gondii (T. gondii) seropositivity may be associated with decreased memory in older adults. To further investigate the association between T. gondii seropositivity and memory in nondemented older adults, we obtained serum samples from 114 non-demented older adults evaluated by the Alzheimer’s Disease and Research Center at Washington University in St. Louis Missouri, USA. We determined T. gondii seropositivity and anti-T. gondii IgG antibody titer and examined associations with memory function while controlling for socioeconomic status, education level, age, and apolipoprotein E4 status. There were few associations between T. gondii seropositivity or anti-T. gondii IgG antibodies and memory, although there …

Color Between The Lines: Navigating Mixed Race Identity, Kelly O'Halloran

College Honors Program

Through the qualitative work of narrative psychology, this thesis explores experiences of mixed race individuals who have one white parent, one minority parent, and who grew up in a predominantly white community. The data were drawn from the author’s own first-hand experiences as well as in-depth interviews from three Holy Cross students about their mixed race identities. On the basis of these data, three forms of self-identity were found to be especially salient: the unaware self, the unique self, and the liminal self. The unaware self can be understood as not knowing how one appears to others. The unique self …

The Relationships Among Moral Judgement, Social Identification, And Stigmitization, Rebecca Isaacs

Mahurin Honors College Capstone Experience/Thesis Projects

Stigma has had a perceived link with the concept of morality since the Grecian era (Goffman, 1963). The purpose of this study was to see if there was a correlation between moral judgement (using the Defining Issues Test 2; DIT2), social identification (using the Identification with all Humanity Scale; IWAHS) and stigma attributions toward those with mental illness. Specifically, whether those with a heightened sense of identification with all humanity and more developed moral judgement schemas are less likely to make negative stigma attributions toward persons with mental illness. The results this study supported correlations between those variables and the …

Flow, Creativity And Autism Spectrum Disorder: Creatively Supporting Development And Pro-Social Behavior In Children With Asd, Mehdi Raoufi

Expressive Therapies Capstone Theses

This literature review is an analysis of the literature exploring the use of expressive arts modalities with children living with Autism Spectrum Disorder (ASD), with a focus on emotional regulation and behavior modification. Historically, Applied Behavior Analysis (ABA) has been the standard in terms of behavior modification for this population, but current research and qualitative inquiries suggested that members of this population need more support in emotional regulation and communication than ABA is able to provide. Using an intermodal arts-based method developmentally promotes social and communication abilities in children with ASD. Further, channeling stereotypic behaviors into creative flow can regulate, …

The Effect Of Smartphones On Anxiety: An Attachment Issue Or Fear Of Missing Out?, Kelly Mannion

Seton Hall University Dissertations and Theses (ETDs)

Previous research shows that college students tend to experience increased anxiety when they are separated from their smartphone. This anxiety has been suggested to be due to attachment, where college students have formed an attachment to their smartphone. Another explanation for this anxiety is the fear of missing out (FoMO), where college students experience worry when they cannot check in with their friends. No existing study to my knowledge has simultaneously examined the separate impact of attachment to phones and FoMO on anxiety levels, particularly during a stressful situation. The current study examines the separate and combined impacts of FoMO …
