Finding The Green-Eyed Monster In The Brain Of A Dog, Peter Singer

Animal Sentience

That dogs show behavior suggestive of jealousy has long been known and has been demonstrated under controlled conditions. Cook et al. have now shown arousal in the amygdala when dogs see a caregiver feeding another dog. This finding has ethical significance in two respects. First, the consideration shown by the investigators for the welfare of their experimental subjects sets an example for other researchers using animals. Second, the greater understanding of the emotional lives of animals should lead to more concern for their needs.

Jealousy, Competition, Or A Contextual Cue For Reward?, Thomas R. Zentall

Animal Sentience

Emotions are difficult to assess, even in humans. The attribution of jealousy in an animal like a dog is especially difficult because performance of a particular behavior in the context of another animal receiving a reward may not be easily distinguishable from intra-species competition or simply a response to a contextual cue for the availability of reward. The authors provide distinguishing evidence in the form of fMRI data to show that in the presence of a “fake” dog being fed, there is bilateral activation in the amygdala, an area associated with anxiety, anger, fear, and even jealousy in humans.

On Jealousy, Envy, Sex Differences And Temperament In Humans And Dogs, Eddie Harmon-Jones, Sylvia K. Harmon-Jones

Animal Sentience

Cook, Prichard, Spivak, and Berns (2018) find that dogs’ levels of trait aggression are positively correlated with their amygdala activation when observing their caregivers giving a food to a fake dog. The authors conclude that this may provide neural evidence in dogs for the experience of jealousy, an emotion that some psychologists consider to be unique to humans. Here we explain the difference between the emotions of jealousy and envy, suggesting some ideas for future experiments that may help disentangle the experience of jealousy from that of envy in dogs. We also propose ideas for future research that may yield …

Can A Dog Be Jealous?, Yaoguang Jiang, Annamarie W. Huttunen, Michael L. Platt

Animal Sentience

Whether humans alone experience complex emotions like jealousy or envy remains hotly debated, partly because of the difficulty of measuring them without a verbal report. Cook, Berns and colleagues use functional brain imaging to identify in dogs neural responses very similar to those evoked by jealousy in humans. When dogs see their caregiver reward a facsimile dog, their amygdala is activated and the strength of this response predicts aggressive behavior — just as jealousy leads to aggression in humans. The authors conclude that dogs feel something very similar to human jealousy. This novel and creative study tackles one of the …

Understanding Dogs' Neural Responses In A Food-Giving Paradigm, Zachary A. Silver, Laurie R. Santos

Animal Sentience

In their target article, Cook et al. provide exciting new insights into dogs’ neural responses when they watch their caregivers giving food to a fake dog or placing it into a bucket. The use of fMRI in awake and unrestrained dogs is tremendously valuable for understanding canine emotionality. We worry, however, that it is too soon to conclude that the reported pattern of amygdala activation corresponds to a specific emotion. Further testing will be essential to determine whether this amygdala activation is indeed an expression of jealousy.

Fake Or Not: Two Prerequisites For Jealousy, Juliane Bräuer, Federica Amici

Animal Sentience

Cook and colleagues (2018) use a novel approach to test jealousy in dogs. Although such a non-invasive approach is more than welcome in comparative research, several methodological shortcomings limit the impact of this study. We briefly outline two main problems. (1) There is no evidence that the fake dogs in the study were perceived as real, and thus as social rivals, which would be a prerequisite for jealousy. (2) It is questionable whether dogs generally show the cognitive prerequisites for jealousy, such as attentiveness toward a social rival, the ability to understand intentions, and a sense of fairness. We suggest …

Fill-In-The-Blank-Emotion In Dogs? Evidence From Brain Imaging, Alexandra Horowitz, Becca Franks, Jeff Sebo

Animal Sentience

What is needed to make meaningful claims about an animal’s capacity for subjective experience? Cook et al. (2018) attempt to study jealousy in dogs by placing them in a particular context and then seeing whether they display a particular brain state. We argue that this approach to studying jealousy falls short for two related reasons. First, the relationship between jealousy and the selected context is unclear. Second, the relationship between jealousy and the selected brain state (indeed, any single brain state) is unclear. These and other issues seriously limit what this study can show. It is important not to see …

Expressions Of Optimism Bias And "Self" Versus "Other" Perceived Controllability In The Context Of Military-Related Risks, Lauren Lachica-Muschett

College of Graduate Studies: Theses & Dissertations

This study aimed to examine expressions of optimism bias and perceived controllability specifically regarding risks often associated with military service. Optimism bias refers to people’s tendency to believe they are less susceptible to experiencing negative life events compared to others. Previous studies show high levels of optimism bias are associated with strong perceptions of personal controllability. Optimism bias is a significant aspect of health promotion research particularly in the field of general occupational health and safety (OHS). However, optimism bias has never been investigated in the military OHS domain. Given the number of risks associated with military occupations, examination of …

Not Cruel, Blessed, Or Merciful: Pratchett, Gaiman, And The Personification Of Death, Kiki V. Canon

College of Graduate Studies: Theses & Dissertations

Terry Pratchett and Neil Gaiman helped to change the cultural view of Death personified through their work with the Discworld novels and Sandman comics. Despite taking seemingly different paths in portraying Death, these two authors presented a cohesive view of mortality that encourages readers to re-consider the long-held Western cultural notions of Death as a frightening figure to be tricked or avoided at all cost. Despite meeting Barthes’ criteria of the work of “bliss” that changes the mythology of the culture, academic circles frequently overlook the importance of “pop culture” writers, especially when dealing with underrepresented genres such as fantasy, …

The Relationships Among Trauma History, Disordered Eating, Body Dissatisfaction, And Social Anxiety, Rebekah Mitchell

College of Graduate Studies: Theses & Dissertations

Eating disorders are highly prevalent and cause significant psychological impairment, up to and including death (Arcelus, Mitchell, Wales, & Nielson, 2011). This research examined how trauma history in the general population explains variation in eating disorder risk. The purpose of the current study was to provide further evidence for the relationship between abuse history and eating disorder risk. Disordered eating behaviors, body dissatisfaction, and social anxiety are all known risk factors for the development of eating disorders (Brewerton, 2007). Trauma history is related to all three of these known risk factors (Brewerton, 2007) with sexual trauma being more linked to …

A Phenomenological Study Of Teachers' Emotional Responses To Tkes, A High-Stakes Evaluation System, Kristina J. Hirsch

College of Graduate Studies: Theses & Dissertations

Teachers experience a plethora of emotions relating to being evaluated and we are losing a lot of good teachers due to some of these emotions. The purpose of this phenomenological study was to investigate how teachers at one rural high school describe their emotional responses to evaluation and the implementation of TKES as well as if there were gender differences in their responses. This research is important because teachers need to understand that their emotions are not taboo and they are not alone in the evaluation process. Additionally, evaluators benefit from knowing how teachers respond to evaluation so that they …

Quantifying Genetic Responses Of Plants To Drought Stress With A Comparative Transcriptome Approach, Jessica K. Devitt

College of Graduate Studies: Theses & Dissertations

Mentzelia section Bartonia (Loasaceae) commonly occurs in some of the hottest and driest places in North America, but we poorly understand the mechanisms that allow them to tolerate such extreme environments. Morphological and physiological adaptations are well studied in model organisms. The underlying genetic responses to drought stress in non-model organisms like Mentzelia is unknown. To better understand and identify differences and similarities in genetic responses to drought stress between species existing in different habitats with differing water availability, three species from the genus Mentzelia were compared. Species of section Bartonia occur across an environmental gradient, from temperate to arid …

Factors Associated With Iron-Folic Acid Supplement Use Among Pregnant Women In Karu, Nasarawa State, Nigeria - A Cross Sectional Study Using Theory Of Planned Behavior, Toyin O. Akomolafe

College of Graduate Studies: Theses & Dissertations

Introduction: Iron-folic acid supplementation is one of the key interventions provided during antenatal care (ANC) services to reduce iron deficiency, maternal anemia, low birthweight and other pregnancy-related complications responsible for maternal and neonatal mortality. However, use of iron-folic acid supplements and adherence with recommended dosage in Nigeria is low. The purpose of this cross-sectional study was to examine factors associated with iron-folic acid supplements use among pregnant women in Karu local government area (LGA), Nasarawa, Nigeria. Methods: Questionnaires were administered in face-to-face interviews with 64 pregnant women (18 – 49 years old) and 19 healthcare providers in selected …

How Anxiety In Adolescent Athletes May Affect Baseline Neuropsychological Test Scores, Christopher P. Tomczyk

College of Graduate Studies: Theses & Dissertations

Background: Anxiety is highly prevalent in the adolescent population and can affect performance on cognitive tasks. As part of a concussion protocol, measuring cognitive ability through the use of baseline neuropsychological testing is recommended in the high school setting. Because of the cognitive nature of baseline testing, there is potential for anxiety to influence scores. Purpose: To examine the effects of varying levels of state and trait anxiety on a baseline computerized neurocognitive assessment in the adolescent population. Methods: 75 adolescent athletes (age:15.91±1.33, height (cm): 168.72±9.07, weight (kg): 62.97±12.04) participated in the study. Cognitive ability was measured …

Morphological And Behavioral Traits Associated With Locomotion In Lizards, Chase T. Kinsey

College of Graduate Studies: Theses & Dissertations

Morphology, locomotion, and behavior are co-adapted to optimize performance and ultimately fitness. Successfully navigating a complex environment is dictated by an animal’s locomotor behavior, and for some behaviors, its locomotor performance. The locomotor performance of an organism is directly related to the form and function of the structures involved in locomotion such that movement is efficient – that is, minimal loss of energy. The first chapter of this thesis focuses on the effects of obstacle placement and forelimb position on facultative bipedalism. Placing an obstacle beyond a lizard’s acceleration threshold did not affect the frequency of bipedal posture. Furthermore, the …

Functional Analysis Of Tattoos From An Evolutionary Perspective, Elise V. Neville

College of Graduate Studies: Theses & Dissertations

Recently, rates of tattooing in the U.S. have surged despite evidence of negative perceptions of individuals with tattoos. Additionally, perceptions appear to vary by target gender, with tattooed women being perceived more negatively than their male counterparts. The purpose of the current research was to examine (a) if perceptions of those with tattoos indeed vary by gender, (b) if tattoos conceivably serve an evolutionary function and (c) if so, do tattoos serve different functions for women and men. An evolutionary approach takes into consideration the purpose an observed behavior may serve for the individual in terms of how it solves …

Lowcountry Identities, Labor, And Material Culture: An Archaeological Survey Of 38ja1138, Zachary W. Dirnberger

College of Graduate Studies: Theses & Dissertations

Archaeologists have long struggled with understanding the relationship between material culture and actual, emic identity. Early practitioners assumed that there was a one-to-one correspondence between the two and that a suite of artifacts recovered archaeologically could be matched with a specific ethnic affiliation or peoples that produced and utilized those artifacts. Later generations of archaeologists challenged this view by demonstrating how mutable and historically situated identity is, and how often material culture crosscuts ethnic boundaries. Historical archaeologists have played a central role in this debate. In this thesis, I examine 38JA1138, a largely undocumented late eighteenth-century site in Jasper County, …

Synthesis And Behavior Characterization Of Multi-Scale Hierarchical Structured Composites, Jacob M. Mayfield

College of Graduate Studies: Theses & Dissertations

The purpose of the synthesis of a multi-scale hierarchical composite material was to create a material with a high specific strength, a low mass, and high strength material. To achieve this the material categorization of the Formlabs Tough V2 resin was conducted. The resin was used in the construction of a bio-mimicry diamond lattice structure. The structure was subjected to compression testing to characterize the material properties. The Tough V2 resin structure combined with cellulose created a multi-scaled material on Macro and Micro levels to show the bio-inspired design to increase the material properties in a favorable manor. The Tough …

Old English Character Recognition Using Neural Networks, Sattajit Sutradhar

College of Graduate Studies: Theses & Dissertations

Character recognition has been capturing the interest of researchers since the beginning of the twentieth century. While the Optical Character Recognition for printed material is very robust and widespread nowadays, the recognition of handwritten materials lags behind. In our digital era more and more historical, handwritten documents are digitized and made available to the general public. However, these digital copies of handwritten materials lack the automatic content recognition feature of their printed materials counterparts. We are proposing a practical, accurate, and computationally efficient method for Old English character recognition from manuscript images. Our method relies on a modern machine learning …

Saccadic Eye Movements Between Strategic, Interceptive, And Non-Athletes, Brian Szekely

College of Graduate Studies: Theses & Dissertations

Introduction: Athletes have differences in object tracking, search strategies, number and duration of fixations, dynamic visual acuity (DVA), and predictive eye movements than non-athletes (NON). However, these eye functions have not been assessed between athlete groups during a task that encompasses antisaccade and DVA characteristics. Purpose: To evaluate the oculomotor control sport paradigm differences between interceptive (INT) and strategic (STR) Division I collegiate athletes, as well as NON with an antisaccade task (AS) and a sport-like dual task (SDT). Methods: Fifty-seven participants (19 STR, 19 INT, and 19 NON) performed 2 trials of an AS and a SDT. Participants stood …

Multiclass Classification Of Risk Factors For Cervical Cancer Using Artificial Neural Networks, Abdullah Al Mamun

College of Graduate Studies: Theses & Dissertations

World Health Organization statistics show that cervical cancer is the fourth most frequent cancer in women with an estimated 530,000 new cases in 2012. Cervical cancer diagnosis typically involves liquid-based cytology (LBC) followed by a pathologist review. The accuracy of decision is therefore highly influenced by the expert’s skills and experience, resulting in relatively high false positive and/or false negative rates. Moreover, given the fact that the data being analyzed is highly dimensional, same reviewer’s decision is inherently affected by inconsistencies in interpreting the data. In this study, we use an Artificial Neural Network based model that aims to considerably …

The Role Of Psychosocial Factors In The Non-Medical Use Of Prescription Stimulants Among Undergraduate Greek-Life Members, Kathleen May

College of Graduate Studies: Theses & Dissertations

The non-medical use of prescription stimulants (NMUPS) is a growing concern across U.S. college campuses. Amphetamine misuse increased from 7.7% to 11.1% among undergraduate students over the past decade. Research has identified Greek-life members are twice as likely to report NMUPS in comparison to non-Greek-life members; however, little is known about social and psychological factors contributing to this discrepancy. While researchers have identified specific personality characteristics significantly correlated with higher levels of reported NMUPS, including sensation seeking and internal restlessness, currently little is known about social factors related to NMUPS. It is important to examine psychosocial variables motivating NMUPS in …

Evaluating Elasmobranch Bycatch And Shark Depredation In The Georgia Shrimp Fishery, Matthew M. Scanlon

College of Graduate Studies: Theses & Dissertations

The Georgia shrimp fishery has seen a dramatic decrease in profit and productivity since the 1980’s due to a number of economic factors. Additional, yet undocumented, pressures on this fishery include interactions between foraging sharks with trawl gear. Fishermen report that sharks frequently bite nets in an attempt to prey on netted fish, resulting in large holes in the gear. Further elasmobranch interactions with trawl gear occur as bycatch; shrimp trawls represent nearly 100% of elasmobranch commercial bycatch in Georgia state waters, the species composition of which is largely unstudied. Shark interactions with nets were detailed through fishery-dependent observations on …

Environmental And Physiological Regulation Of Yellow Stingray Color Change, Theresa Rose Gunn

College of Graduate Studies: Theses & Dissertations

Many reef fishes exhibit dynamic coloration and body patterns that can change under nervous or hormonal control. Several species of benthic sharks and rays likely alter melanin in the skin to provide background matching for camouflage. The yellow stingray (Urobatis jamaicensis) is a benthically-oriented elasmobranch with elaborate spot patterns that provide effective camouflage within its habitats. This patterning, when coupled with the ability to alter melanin in response to background color, could increase background matching effectiveness in these species. The yellow stingray has been anecdotally noted to lighten or darken skin color.However, it is unclear whether this type …

College of Graduate Studies: Theses & Dissertations

Statement of the Problem: Men who have sex with men (MSM) are at disproportionate risk for HIV infection. While many studies have examined psychosocial factors associated with HIV risk among MSM, few have focused specifically on MSM in the military. The purpose of this exploratory study is to examine ways in which specific psychosocial factors are associated with sexual risk behaviors among MSM in the military.

Methods: Data were collected from 63 MSM who were active duty military personnel or veterans in the Southeastern US. Participants were recruited from geosocial mobile applications, social media platforms, and military LGBT organizations. Logistic …

(2018) Philosophy For/With Children, Religious Education And Education For Spirituality. Steps Toward A Review Of The Literature, Maughn Gregory, Stefano Oliverio

Collected Papers of Maughn Rollins Gregory

The authors describe the organization of a review of research literature on the relationship between Philosophy for/with Children (P4/wC) and religious education/education for spirituality (RE-EfS). They summarize a debate about whether the two are mutually enhancing or incompatible. They explain delimiting the scope of the project and present a grid of research questions used to analyze the literature. They summarize findings on how P4/wC is relevant to five categories of aims of RE-EfS: hermeneutical, cultural, socio-political, moral/spiritual, and epistemological. Many papers in the latter category promote P4/wC as a method for children’s epistemic agency in constructing their religious beliefs. Some …
