Effects Of Prenatal Exposure To Phenobarbital On Verbal Abilities In School-Aged Children, Jocelyn M. Lutes

Graduate Masters Theses

Phenobarbital is one of the oldest medications used for the treatment of epilepsy. Although its use has declined in many developed nations, phenobarbital is still a first-line treatment in several developing countries across the globe. If possible, current American Academy of Neurology guidelines advise against the use of phenobarbital during pregnancy due to an increased risk for structural malformations. However, less is known about the risk that prenatal exposure to phenobarbital poses to the cognitive and behavioral development of the child. Adams et al (in progress) have shown that, in comparison to demographically matched controls, children prenatally exposed to phenobarbital …

(Non-Consensual) Sex, Drugs & Rock N’ Roll: Sexual Harassment And Violence At Live Music Events, Miliaikeala Sj. Heen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music concerts and festivals draw millions of attendees in the United States and internationally annually. Half of the U.S. population goes to live music events each year, with 33% going to concerts and 18% going to festivals (Nielsen Music 360, 2017). Despite the fact that these events provide security for the safety of both performers and attendees, the context of these events may facilitate various forms of sexual violence. Research has revealed high levels of harassment, groping, and other forms of unwanted sexual behavior at music festivals and concerts. The current study will utilize a national survey to examine unwanted …

Musical Meter: Examining Hierarchical Temporal Perception In Complex Musical Stimuli Across Human Development, Sensory Modalities, And Expertise, Jessica Erin Nave-Blodgett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Performing, listening, and moving to music are universal human behaviors. Most music in the world is organized temporally with faster periodicities nested within slower periodicities, creating a perceptual hierarchy of repeating stronger (downbeat) and weaker (upbeat) events. This perceptual organization is theorized to aid our abilities to synchronize our behaviors with music and other individuals, but there is scant empirical evidence that listeners actively perceive these multiple levels of temporal periodicities simultaneously. Furthermore, there is conflicting evidence about when, and how, the ability to perceive the beat in music emerges during development. It is also unclear if this hierarchical organization …

Eyewitness Recall And Identification Accuracy: Effects Of Stress In An Extreme Haunt And A Haunted House, William Blake Ridgway

UNLV Theses, Dissertations, Professional Papers, and Capstones

The impact of stress on eyewitness recall and identification accuracy has been studied extensively but with somewhat inconsistent results. Understanding the effects of stress are important if they are to be generalized to victims or witnesses of real crimes. This study consisted of two experiments that used an extreme haunt and a haunted house to examine attendees’ ability to recall details of and identify actors encountered, as a function of state anxiety and in the context of Deffenbacher’s (1994) catastrophe model of memory performance under anxiety. The results showed that physiological (i.e., heart rate) and psychological (i.e., State Anxiety Inventory) …

Examination Of Factors Reported By Athletes To Interfere With Their Lives Outside Of Sports, Jesse Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The original Sport Interference Checklist (SIC) is a mental-health screening instrument designed to assess the extent to which mental health factors interfere with athletes’ performance during sport training or competition. In addition, the SIC appraises whether athletes are interested in pursuing psychological treatment for the aforementioned factors. Although validated, the SIC does not assess how the aforementioned factors affect athletes’ performance outside of sports. Doing so would permit professionals to examine the influence of these factors across sport training, sport competition, and life outside of sports.

The purpose of this study was to determine the psychometric properties and clinical utility …

An Economic Comparison Of Two Leading Aquaponic Technologies Using Cost Benefit Analysis: The Coupled And Decoupled Systems, Grace M. Gibbons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aquaponics is an agricultural production practice which combines aquaculture, the raising of fish, and hydroponics, a soil-less crop production method, to create a system that symbiotically produces both. Compared to conventional open-field agriculture, this practice is highly resource efficient in terms of water and land usage, but has yet to be widely adopted due to a lack of research regarding its economic feasibility. This study compares the two most economically promising aquaponic system designs to determine which would be more profitable at the intermediate-commercial scale. The first of these is the coupled system which continuously circulates water in a closed …

The Role Of Information And Communication Technology (Ict) In Securing Books In Irish Academic Libraries., Emmanuel Oguche

Library Philosophy and Practice (e-journal)

This study examined how effective the ICT gadgets are used in securing books in academic libraries and what technological approach the libraries will adopt in the future to ensure books are secured from mutilation and theft. The study was also to understand why students steal or mutilate books. A semi-structured interview was the qualitative research design used to collect data from six librarians. It was discovered that the libraries had adopted the use of ICT security gadgets like Radio-Frequency Identification (RFID) technology, surveillance cameras, self-service machine, magnetic strips. The combined use of these gadgets led to the drastic reduction of …

Exploring The Relationship Between Mindfulness, Self-Compassion, And Empathy In Student Therapists, Nicole Montes

Dissertations

Literature suggests that the practice of mindfulness may foster self-compassion within the practitioner. Mindfulness is also associated with increased empathy towards others. The current study explored the relationship between a mindfulness intervention and student clinicians’ levels of self-compassion and empathy towards a mock “client.” Graduate student clinicians were randomly assigned to two groups: one that participated in a mindfulness exercise then viewed a mock client video, and another that did not participate in the mindfulness exercise and went directly to viewing the mock client video. Participants’ levels of empathy towards the client and self-compassion were measured. The results revealed no …

The Effects Of Exaggerated Social Comparison Feedback On Work Performance, Michael Patrick Cusick

Theses and Dissertations

The purpose of this study was to examine the effects of exaggerated social comparison feedback on work performance in an analogue setting. Following their first 15-minute session working on a simulated money transfer task, participants in the two experimental conditions received objective feedback, but one group received rank feedback understating their performance, while the other group received overstated rank feedback. Participants then performed the task again to evaluate potential changes in performance based on this feedback. One-way analyses of variance (ANOVAs) were conducted to measure differences in the number of correctly completed money transfers, percent of correctly completed money transfers, …

Knowledge, Interest, And Motivations Surrounding Self-Managed Medication Abortion Among Patients At Three Texas Clinics, Abigail R.A. Aiken, Kathleen Broussard, Dana M. Johnson, Elisa Padron, Jennifer E. Starling, James G. Scott

Faculty Publications

Background: A rapid increase in restrictive abortion legislation in the United States has sparked renewed interest in self-managed abortion as a response to clinic access barriers. Yet little is known about knowledge of, interest in, and experiences of self-managed medication abortion among patients who obtain abortion care in a clinic.

Objectives: We examined patients’ knowledge of, interest in, and experience with self-managed medication abortion before presenting to the clinic. We characterized the clinic- and person-level factors associated with these measures. Finally, we examined the reasons why patients express an interest in or consider self-management before attending the clinic.

Developing A Maceration Method For Isolation Of Dna From Cancellous Bones, Bryan Bernal

Student Theses

Prior to isolating DNA, it is necessary to remove any biological materials that may be present on commingled remains. Manual maceration of the outer surface is time-consuming. This study will address this issue by developing a simple method for processing bone samples prior to DNA isolation. A liquid-based technique was applied to macerate bone fragments by incubating bone fragments in an enzyme solution, removing potential contaminants, followed by a bone tissue disruption. Swine (Sus scrofa) bones were used to simulate human bones. Microscopic analysis suggested this method was effective for surface material removal. The methods effect on the …

The Application Of A Simple Tissue-Disruption Method To Dna Extraction For Species Identification, Jordana R. Fox

Student Theses

The TissueLyser II was used to disrupt animal bones and plant tissue without dry ice or liquid nitrogen for species identification. Bone fragments of fresh swine (Sus scrofa) ribs were used. A 521bp fragment of the cyt b locus was analyzed, and the BLASTn results confirmed that the origin of all the samples was swine (E-value = 0.0). Bone fragments of bovine, chicken, duck, fish, sheep, and swine were also used to test the procedure. An approximately 600bp fragment of the COI locus was analyzed, and the BLASTn results confirmed the origin of all the samples (E-value = …

Archaeology Or Crime Scene? Teeth Micro And Macro Structure Analysis As Dating Variable, Jessica A. Vincenty

Student Theses

Simple methods to aid in the determination of forensic or archaeologic relevancy of skeletonized remains have been researched since the 1950s. With advances in microscopic imaging techniques and machine learning computer data analysis methods the relevancy of decontextualized, comingled remains has room for improvement. This thesis is a study done to pioneer a new approach to analyzing dental skeletal remains to determine forensic relevancy.

Archaeological dental samples collected from the ancient city of Ur in modern day southern Iraq in addition to modern dental extractions were processed for scanning electron microscopy imaging. Archaeological and modern samples displayed different surface and …

Hostile Attributions To Ambiguous Situations: A Vignette Study Of The Mediating Role Of Hostile Attributions In The Relationship Between Community Violence Exposure And Youths’ Aggressive Behaviors, Hyun Kim

Student Theses

The effect of exposure to community violence has received increasing attention in recent years, given its prevalence and negative psychological and behavioral consequences on adolescents, including aggression (Lambert et al., 2018). The existing literature links violence exposure to hostile interpretation of situations (Dodge et al., 1990; Huesmann, 1988), and hostile interpretations to aggressive responses (Bradshaw et al., 2009; Crick & Dodge, 1994; Dodge et al., 1990). However, most studies have focused on parenting practices and within home violence. Few studies have examined the possible mediating role of hostile attribution bias in the relationship between community violence exposure and youth aggression, …

The Effects Of Podcasts On Mental Health Stigma, Sarah N. Dure

Student Theses

Research indicates that media can have both negative and positive impacts on mental health stigma and self-stigma. No studies, to our knowledge, have examined the impact of audio media representation (podcasts) on mental health stigma. Our study therefore examines the effects that both positive and negative portrayals of mental illness in a news podcast would have on mental health stigma. We hypothesized that participants assigned to podcast conditions that primed for mental illness would lead participants to attribute an incident to mental illness. Additionally, we hypothesized that listening to a podcast that speaks negatively about individuals with mental illnesses would …

Mock Jurors' Perceptions Of "I Don't Know" Answers In Child Testimony, Leanza Greenlee

Masters Theses and Doctoral Dissertations

Attorneys questioning child witnesses often ask complex questions that negatively impact children’s accuracy and consistency. Research has shown that instructing children to answer confusing questions with “I don’t know” can improve their accuracy, but little research has examined the impact of using this strategy on jurors’ perceptions of child witness credibility. The present study assessed 702 mock jurors’ perceptions of a 4- or 10-year-old child witness in a fabricated sexual assault trial transcript. Number of “don’t know” responses were manipulated, and half the jurors were told about the “I don’t know” instruction. Results demonstrated that greater numbers of “I don’t …

Natural Disasters And Attachment Quality: The Mediating Roles Of Self-Compassion And Positive Mental Health, Alexandra Teller

Dissertations

Emerging adults exposed to natural disasters may develop posttraumatic stress symptoms, mood disorders, and anxiety disorders. Attachment quality has been found to be negatively associated with psychopathology in emerging adult hurricane survivors; however, the mechanisms by which this occurs have not yet been explored fully. Self-compassion may act as a protective factor against developing psychopathology while potentially promoting positive mental health outcomes following hurricane exposure. Furthermore, positive mental health has been identified as a potential resilience resource and may be impacted by attachment quality and self-compassion. The present study investigated the relationships between attachment quality, self-compassion, positive mental health, posttraumatic …

Evaluating The Effects Of Behavior Bingo On Students' Academically Engaged Behaviors, Kristi White

Dissertations

This study sought to extend the current literature regarding the use of an interdependent group contingency intervention (i.e., Behavior Bingo) for increasing students’ academically engaged behavior and decreasing students’ disruptive behaviors. Participants included three 6th grade Science teachers and their students. An ABAB design across classrooms was used to examine the effects of the Behavior Bingo intervention on students’ behaviors. Specifically, this study consisted of four phases: a) baseline, b) behavior Bingo intervention, c) withdrawal from intervention, and d) intervention reinstated. Results indicated increases in student’s academically engaged behaviors following implementation of the Behavior Bingo intervention with moderate to large …

Using Two Reinforcement Contingencies To Alter Teachers' Rates Of Praise, Ashleigh Eaves

Dissertations

The current study evaluated the effects of a positive and negative reinforcement contingency on teachers’ use of behavior specific praise (BSP) in the educational setting. An alternating treatments design was used across four participants in a rural, Southern elementary to determine if one or both conditions was successful in increasing the use of BSP. Data were collected on teachers’ use of BSP, general praise, general reprimands, and behavior specific reprimands (BSR). Additionally, student engagement in academically-associated and/or disruptive behaviors was measured throughout baseline, treatment, and follow-up phases. Results indicate both the positive and negative reinforcement contingency were successful in improving …

The Roles Of Violence Exposure And Gender On The Relationship Between Adolescent Psychopathic And Conduct Disorder Traits And The Capability For Suicide, Tiffany Harrop

Dissertations

Suicide represents one of the leading causes of mortality for adolescents. Externalizing behaviors, such as psychopathic and conduct disorder traits, represent risk factors for adolescent suicide. Investigation of suicide capability is especially important, as it is theorized to distinguish individuals who evince suicide ideation from those who progress to making a suicide attempt. Currently, associations between psychopathic and conduct disorder traits and capability in youth are understudied, as well as factors that may potentiate these associations, such as exposure to violence and gender. The aim of this study was to explore the interactive nature of psychopathic and conduct disorder traits, …

Multi-Tiered Systems Of Support For Head Start Teachers Behavior Specific Praise, Elizabeth Lown

Dissertations

A variety of evidence-based studies have examined teachers’ intervention implementation and its effects on student outcomes. This study tested a Multi-Tiered Systems of Support approach to supporting teachers’ intervention implementation. Specifically, the Multi-Tiered Systems of Support approach was comprised of Tier 1 (didactic training), Tier II (tactile prompting), and Tier III (performance feedback). The primary dependent variable was Head Start teachers' use of behavior specific praise. Secondary dependent variables included teachers' use of reprimand statements and child outcomes, which included academically engaged behavior and disruptive behavior. This study further examined if Head Start teachers' use of behavior specific praise was …

The Role Of Acculturation And Acculturative Stress In The Association Between Generational Status And Factors Related To Suicide Among South Koreans In The United States, Hyejin Jin

Dissertations

Korean Americans have the highest suicide mortality rates among Asian American subgroups (6.84 per 100,000 population; U.S. Census Bureau, 2010). Therefore, it may be important to examine the unique factors that account for the suicide rates of Korean Americans, especially since current knowledge on suicide with Korean Americans is limited. Thus, the present dissertation study sought to examine the role of acculturation and acculturative stress in the association between generational status and factors related to suicide among Korean Americans.

A sample of 150 participants completed a study protocol consisting of various self-report measures on MTurk. The results supported the hypothesis …

Exploring The Maladaptive Cognitions Of Moral Injury, Rachel L. Martin

Dissertations

Moral injury and Post-Traumatic Stress Disorder (PTSD) are two prominent mental health problems that affect military personnel. Moral injury results when the individual is exposed to a situation or event that violates their moral code; however, PTSD results when there is a substantial threat of harm. Moral injury is a relatively new construct within the literature with research starting in the late 2000s. Although distorted cognitions are core components of PTSD symptomatology, there has been no research of cognitions in moral injury. The current study sought to differentiate PTSD and moral injury using the specific maladaptive cognitions associated with trauma …

An Examination Of Parental Locus Of Control, Stress, Social Support, And Depression Among Parents Of Children And Adolescents With Intellectual Disabilities, Brandi Ellis

Dissertations

Caregivers (i.e., mothers and fathers) of youths with ID seem to be at a much higher risk of having symptoms of depression than caregivers of typically developing youths (Cantwell, Muldoon, & Gallagher, 2015; Giallo et al., 2015; Hu et al., 2010; Lee, 2013). A concurrent link has been found between parental locus of control (PLOC) and depression; however, there is a lack of support for a longitudinal association between these constructs among caregivers of youths with ID (Campis, Lyman, & Prentice-Dunn, 1986; Coyne & Thompson, 2011; Freed & Tompson, 2011; Lloyd & Hastings, 2009). Researchers have hypothesized that the lack …

Brief Intervention With Holland’S Theory And Vocational Calling: Three Conditions With Pre-Existing Calling Status As A Covariate, Nathan Ross

Dissertations

In a series of workshops, Holland’s RIASEC Theory and elements of Cognitive Information Processing Theory were infused with vocational calling language. Participants were largely college freshman in a community learning group and students participating in an extra credit opportunity in the School of Psychology. An in-person quasi-experimental design compared outcomes between three career workshops (i.e., Holland, Calling, and Control) on career decision-making self-efficacy, cognitive and emotional career decision-making difficulties, and vocational identity. The Calling workshop outperformed Holland and Control for all measured career variables (i.e., career decision-making self-efficacy, cognitive career decision-making difficulties, emotional and personality career decision-making difficulty, and vocational …

A Parametric Analysis Of Opportunities To Respond On Academically Engaged Behavior, Morgan G. Mccargo

Dissertations

The purpose of this study was to evaluate the adequate rate of opportunities to respond (OTR) to provide to students that would result in the highest rates of Academically Engaged Behavior. This study utilized a parametric analysis to evaluate and assess the effects of altering the number of OTR provided per minute (i.e., 1, 3, 5) on academically engaged behavior, disruptive behavior, and passive off-task, as an antecedent intervention in a general education elementary school setting. An alternating treatments design was utilized with three treatment conditions. All treatment conditions were implemented in a predetermined pattern, meeting the standards of Kratochwill …

Romantic Relational Aggression Among College Students: A Moderated Mediation Study Of Attachment Style, Romantic Jealousy, Mate Value, And Relationship Investment, Skylar Hicks

Dissertations

Most of the research on intimate partner violence has concentrated on overt physical and verbal aggression, and less is known about relational aggression in the framework of romantic relationships. Relational aggression is more prevalent in college students’ romantic relationships compared to physical aggression and may be a risk factor for intimate partner violence. Additionally, a number of adverse correlates have been associated with romantic relational aggression, suggesting that it is worthy of study independent of its association with intimate partner violence. The present study explored the relationships among adult attachment, romantic jealousy, mate value, relationship investment, and romantic relational aggression …
