Down Syndrome, The Image Of God, And Personhood, Paris Webb

Dialogue & Nexus

People with Down syndrome help Christians understand what being made in the image of God truly means. After describing Down syndrome, we will examine the different views of the image of God and how these relate to people with Down syndrome. Another approach will be to define personhood in light of God’s image and relate it to Down syndrome. We will use the principles held by the L’Arche community as an exemplar in this discussion to demonstrate that those with Down syndrome encourage us to expand our understanding of the image of God. Consequently, Down’s persons allow us to apply …

The Effects Of Nicotine In The Neonatal Quinpirole Rodent Model Of Psychosis: Neural Plasticity Mechanisms And Nicotinic Receptor Changes, Daniel J. Peterson, W. Drew Gill, John M. Dose, Donald B. Hoover, James R. Pauly, Elizabeth D. Cummins, Katherine C. Burgess, Russell W. Brown

Pharmaceutical Sciences Faculty Publications

Neonatal quinpirole (NQ) treatment to rats increases dopamine D2 receptor sensitivity persistent throughout the animal’s lifetime. In Experiment 1, we analyzed the role of α7 and α4β2 nicotinic receptors (nAChRs) in nicotine behavioral sensitization and on the brain-derived neurotrophic factor (BDNF) response to nicotine in NQ- and neonatally saline (NS)-treated rats. In Experiment 2, we analyzed changes in α7 and α4β2 nAChR density in the nucleus accumbens (NAcc) and dorsal striatum in NQ and NS animals sensitized to nicotine. Male and female Sprague-Dawley rats were neonatally treated with quinpirole (1 mg/kg) or saline from postnatal days (P)1–21. Animals were given …

Model And World: Generalizing The Ontic Conception Of Scientific Explanation, Mark Povich

Arts & Sciences Graduate Student Theses and Dissertations

Model and World defends a theory of scientific explanation that I call the “Generalized Ontic Conception” (GOC), according to which a model explains when and only when it provides (approximately) veridical information about the ontic structures on which the explanandum phenomenon depends. Causal and mechanistic explanations are species of GOC in which the ontic structures on which the explanandum phenomenon depends are causes and mechanisms, respectively, and the kinds of dependence involved are causal and constitutive/mechanistic, respectively. The kind of dependence relation about which information is provided determines the species of the explanation. This provides an intuitive typology of explanations …

Unreplicable: The Unscientific Nature Of Science Journals, Ernest M. Oleksy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Academia shapes the way our species looks at veracity and defines what is deemed as well-founded science. The platform for researchers to make their work known is academic journals. The prerogative of these journals is to disseminate technically sound work so that the public may be informed of up-to-date advances in scientific fields. However, these journals are products on the market whose ultimate purpose is to garner a following that will make the producers money. This results in research that does not have statistically significant findings, or replications of past experiments which are integral to supporting the findings of the …

Assessing Behavioral Syndromes In Captive Red Pandas (Ailurus Fulgens) Using An Ethological Approach, Tyler C. Bray

Theses and Dissertations

Animal personality has a significant impact on an animal’s physiology and welfare. Eight captive red pandas were observed to determine if personality can be assessed in this species using an ethological approach. Analysis revealed two behavioral dimensions: 1) Active/Exploratory and 2) Maintenance. Age differences were found in the Active/Exploratory dimension.

Effect Of Activity Trackers And Text Messaging On Exercise, Fitness, And Physical Activity Self-Efficacy Of Middle School Students, Alison F. Pittman

Nursing Theses and Dissertations

A decrease in physical activity as children age is a contributing factor to the U.S. obesity epidemic. Middle school children are particularly vulnerable to sedentary activities. Activity trackers show promise as a means to motivate children and adults to increase physical activity (PA). This study examined the effect of a text messaging intervention and use of activity trackers with a companion social website on the body mass index (BMI), body fat percentage, physical fitness, and PA self-efficacy of middle school children. Children aged 11-14 (n=102) were randomly assigned to one of three groups for a 10-week intervention: activity tracker group; …

Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell

Theses and Dissertations

Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G₂ = 78.10, p < 0.001).

Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris

Thesis Projects

Feather plucking (FP) is a maladaptive behavior observed in captive avian species. This self-injurious behavior results in damage to and removal of feathers and skin tissue, resulting in animal welfare and financial consequences. The etiology and maintenance of FP have been hypothesized through medical and environmental processes, yet a definitive solution has not been found. The current study investigated the environmental variables maintaining the FP of a Black Vulture (Coragyps atratus), as well as evaluated a function-based treatment for this behavior. The behavior was found to be maintained by positive reinforcement in the form of contingent attention. Treatment …

Imposed Versus Affect-Based Resistance Training Intensities On Adherence, Session Affect, Session Perceived Exertion, And Intrinsic Motivation Measures During A Six-Week Program In Novice Female Lifters 2017, Ryan Joseph Brennan

Master's Theses

The American College of Sports Medicine (ACSM) recommends that individuals perform resistance training exercises at a specific intensity based on external load (percentage of one repetition maximum; %1RM). However, only 29.6% of adults in 2013 reported strength training two or more times per week. Furthermore, individuals lifting at recommended percentages vary in their pleasure and displeasure. Self-selected exercise seems to promote positive affective responses, in part, due to the perceived autonomy. The effects of regulating exercise intensity using affect as opposed to imposed intensities as a means for improved fitness, promoting exercise behavior, and enhancing other psychological outcomes have yet …

A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko

Senior Honors Projects

Sexual dimorphism is exhibited across all cricket species and is a central aspect of the mating processes of these insects. Only male crickets possess wing structures and pattern generators in the central nervous system that allow them to produce a mating call that is unique to their species in order to attract conspecific females. Conspecific females possess an auditory feature detection circuit in the central nervous system that is capable of detecting the species-specific frequency and temporal pattern of sound pulses within a male call. In order for dimorphic differences in mating behavior to result in successful continuation of a …

Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere

Master's Theses

Personality has now been studied in species as diverse as chimpanzees (King & Figueredo, 1997) and cuttlefish (Carere et al., 2015), but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only in the bottlenose dolphin (Highfilll & Kuczaj, 2007), while consistent individual differences in a few specific behaviors have been identified in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012). Furthermore, the context component of definitions of personality is not often assessed, despite evidence that animals may show …

Neurostructural Organization And Neocortical Projecting Neuron Distribution In A Mouse Model Of Timothy Syndrome-Mediated Autism Spectrum Disorder, Aiden L. Ford

Neural tissue was processed for either volumetric analysis through Nissl stain (8 TS2-neo, 8 WT) or …

Does Personality Similarity In Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?, Kelsey R. Moreno

Master's Theses

Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; however, mechanisms for formations of specific bonds or patterns in which individuals form which types of bonds have yet to be demonstrated. There is a variety of evidence indicating personality may be a factor in shaping bonds, but this relationship has not been explored with respect to bond components and is yet to be demonstrated …

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

The Effect Of Boat Type On Bottlenose Dolphin (Tursiops Trucatus) Behavior In The Mississippi Sound, Maria Zapetis

Master's Theses

Increases in oceanic shipping are a global phenomenon, and a leading cause of concern for marine animal welfare. While it may be difficult to assess the effect of boat traffic on all species in all contexts, it is vital to report anthropogenic impacts where longitudinal data is available, and doubly so where a dearth of information exists. The purpose of this study is to describe how dolphin behavior changed in the presence of boats in the Mississippi Sound between 2006 and 2012, and more specifically, to detail how different boat types impacted dolphins’ behavioral states. This study is unique in …

Pragmatic Understanding Of Bottlenose Dolphins (Tursiops Truncatus) Use Of A Two-Way Communication System, Pepper Reid Hanna

Dissertations

Pragmatics focuses on how a communication system is used to achieve a communicative goal, the social context of the communication, and the organizational structure of communications (Horn & Ward, 2004; McLaughlin, 1998). There is evidence of pragmatics within animal communication systems. For example, context appears to be an important component in both signal production and a receiver’s response in vervet monkeys (Seyfarth et al. 1980).

MA Thesis: http://aquila.usm.edu/masters_theses/170/

The current study used an underwater keyboard to establish a two-way communication system between humans and dolphins. The purpose of this study was to determine if, under these conditions, dolphins displayed pragmatic …

Anxiety-Like Behaviors And C-Fos Expression In Adult Zebrafish: Effects Of Housing Conditions, Alcohol And Caffeine, Adam Douglas Collier

Dissertations

Alcohol abuse is the third largest risk factor for disease world, responsible for an estimated 3.3 million deaths each year. The concomitant ingestion of alcohol and caffeine is hypothesized to increase risk factors associated with alcohol use alone by reducing subjective effects of intoxication. The zebrafish (Danio rerio) has recently garnered attention from researchers as an effective pre-clinical in-vivo animal model in behavioral pharmacology research, largely due to small size, low-cost and ease of drug delivery. A number of studies have reported the effects of alcohol and caffeine on zebrafish behavior at a variety of doses. However, the …

Efficacy Of Cognitive Enrichment For Bottlenose Dolphins (Tursiops Truncatus): Evaluation Of Planning Abilities Through The Use Of A Novel Problem Solving Task, Lisa Kay Lauderdale

Dissertations

Environmental enrichment is a key component to improving the psychological and physiological well being of animals in human care. Enrichment can be achieved through a variety of modalities, including the addition of objects and scents, or by providing the animals with additional challenges. The effectiveness of specific enrichment should be evaluated on a case-by-case basis to determine if the desired result is achieved. Environmental enrichment devices (EED’s) can be utilized to present novel problems to animals in human care. When confronted with a novel problem, dolphins can plan their behavior to create a more efficient strategy then previously modeled.

Replicability And Reproducibility In Comparative Psychology, Jeffrey R. Stevens

Jeffrey Stevens Publications

Psychology faces a replication crisis. The Reproducibility Project: Psychology sought to replicate the effects of 100 psychology studies. Though 97% of the original studies produced statistically significant results, only 36% of the replication studies did so (Open Science Collaboration, 2015). This inability to replicate previously published results, however, is not limited to psychology (Ioannidis, 2005). Replication projects in medicine (Prinz et al., 2011) and behavioral economics (Camerer et al., 2016) resulted in replication rates of 25 and 61%, respectively, and analyses in genetics (Munafò, 2009) and neuroscience (Button et al., 2013) question the validity of studies in those fields. Science, …

The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Theories considering the etiology of psychopathy suggest that trauma exposure, specifically childhood maltreatment and sexual abuse, is related to the development of callous-unemotional traits in children and adolescents, which are precursors to psychopathic traits in adulthood. Furthermore, posttraumatic stress disorder has an opposite relationship with many of the emotional and behavioral components of the two-factor model of psychopathy. Specifically, PTSD is positively associated to IA and traits associated with it and negatively associated with FD. Thus, this study sought to expand upon the current theories of a trauma-based etiology of psychopathy by investigating the relationship between trauma, PTSD, and psychopathic …

Neural Processes Underlying Auditory Context Effects, Breanne Yerkes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Auditory information within our natural environments is disorganized and often ambiguous, leaving our auditory systems with a complex task: organizing sound into coherent objects. The auditory system uses both current and prior information to assist in completing this task. The influences of previous context on current perception have been referred to as context effects. A contrastive context effect results in a current perception that is opposite of what is expected based on the physical stimulus properties presented during an immediate context. A facilitative context effect results in a current perception that is the same as the perception during the immediate …

Functional Neural Connectivity Associated With Moral Processing In Healthy And Antisocial Samples, Samantha Jean Fede

Psychology ETDs

Although research finds that brain abnormalities during moral decisions underlie traits that lead to crime, understanding of these neural dynamics is limited. Here we use two samples to explore the role network engagement and components during moral processing. We used independent component analysis and functional network connectivity analysis to examine hemodynamic response during an fMRI task of moral processing. Eighty-four community and 539 incarcerated adult men and women participated; MANCOVA and machine learning algorithms were used to identify individual and group differences in both samples. We found patterns of neural engagement and connectivity consistent with proposed models of moral cognition …

Relationship Between Structure And Functional Connectivity Within The Default Mode Network, Andrei A. Vakhtin

Psychology ETDs

We proposed a novel measure of conceptualizing dynamic functional network connectivity (FNC) in the human brain using flexibility of functional connectivity (fFC), which captures the variance of functional connectivity across time. In task-free fMRI scans (N = 122), this measure was demonstrated to correspond to the underlying structural connectivity (SC) within the default mode network (DMN), while static functional connectivity (sFC) did so to a relatively low degree. As SC likely does not develop to facilitate task-free brain function, but rather to integrate information during cognitive engagement, we argue that fFC can estimate the potential functional connectivity exhibited outside of …

Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson

Undergraduate Distinction Papers

Although giant pandas (Ailuropoda melanoleuca) are known to be solitary in the wild, cubs engage in frequent bouts of affiliative behavior in captive settings. The goal of the project was to investigate whether kinship or familiarity based on housing influenced the frequency of social interactions within one-year old giant panda cubs. Data were collected from June through mid-July 2016 at the Chengdu Research Base of Giant Panda Breeding, Sichuan, China. Over 113 hours of behavioral observations were recorded on four sets of twins and one singleton, focusing specifically on affiliative behaviors. Time housed together was a significant predictor of the …

Assessing A Punching Bag Feedback Performance Device, Neil Deochand

Dissertations

Physical exercise has been integrated into treatment efforts in reversing the number of overweight and obese individuals. Furthermore, exercise extends mortality, enhances general quality of life, and it is a protective health factor for preventing the progression some mental health disorders. Electronic athletic training equipment easily allows monitoring of real-time physical activity, and enables tracking of progress made toward individualized performance goals. There are limitations to only using visual feedback (e.g., visual depictions of heart rate, speed, distance traveled, or calories burned etc.) to track and improve exercise and athletic performance, especially for some sports, such as boxing. This issue …

The Mediating Effect Of Self-Determined Motivation In Student-Athlete Perceptions Of Coaching Behaviors And Its Effect On Grit And Mental Toughness, Lloyd Scharneck

Theses and Dissertations

The aim of this current study was to examine the relationship between coaching behaviors, grit, mental toughness, and motivation. I hypothesized that coaching behaviors would have an indirect influence on grit and mental toughness through the motivational orientations of athletes. To examine these relationships, we surveyed 219 student athletes from Midwestern universities using valid and reliable measures assessing the key constructs in this study. Results revealed significant positive relationships between autonomy-supportive coaching, grit, mental toughness and autonomous motivation. Significant negative relationships between controlling coach, grit, and mental toughness were also found. Path analysis revealed two major findings. A significant positive …

A Prototypical First-Generation Electronic Cigarette Does Not Reduce Reports Of Tobacco Urges Or Withdrawal Symptoms Among Cigarette Smokers, Arit M. Harvanko, Catherine A. Martin, Richard J. Kryscio, William W. Stoops, Joshua A. Lile, Thomas H. Kelly

Psychology Faculty Publications

It is unknown whether first-generation electronic cigarettes reduce smoking urges and withdrawal symptoms following a 24 h deprivation period. This study tested whether a first-generation electronic cigarette reduces smoking urges and withdrawal symptoms in cigarette smokers. Following 24 h of tobacco deprivation, using a within-subjects design, eight nontreatment seeking tobacco cigarette smokers (3 females) administered 10 puffs from a conventional cigarette or a first-generation electronic cigarette containing liquid with 0, 8 or 16 mg/ml nicotine. Conventional cigarettes ameliorated smoking urges and electronic cigarettes did not, regardless of nicotine concentration. First-generation electronic cigarettes may not effectively substitute for conventional cigarettes in …
