The Relationship Between College Students’ Purpose In Life And Risk-Taking Behavior, Anna Church

All Master's Theses

The relationship between college students’ sense of purpose in life and their self-reported risky substance use and sexual behavior was investigated. Participants from a northwestern university (N = 174) answered questions online from questionnaires measuring meaning in life, alcohol use, substance use, sexual risk behavior, and social desirability. A MANCOVA analysis was conducted. The results demonstrated no statistically significant effects. Strengths and limitations of the study as well as directions for future research and therapeutic interventions are discussed.

Do Elevated Levels Of Glutathione Decrease The Toxicity Of Plasticizers In Mouse Liver Cells?, Khatoon Albahrani

All Master's Theses

Phthalates are esters of phthalic acid that play a crucial role in the manufacturing industries for enhancing the properties of plastic materials. Di-(2-ethylhexyl) phthalate (DEHP) is one of the most common phthalates used in a variety of products including food packaging and medical equipment. Their use has caused public health concerns because of their toxic effects on reproductive and developmental processes. This study aims to investigate the response of two mouse hepatoma cell lines to the effects of DEHP and its bioactive metabolite mono (2-ethylhexyl) phthalate (MEHP). Cells were exposed to four concentrations (10, 50, 100, and 300 µM) of …

Data Potential Of Archaeological Deposits At The Chelan Station Site, Matthew J. Breidenthal

All Master's Theses

The Chelan Station Site (45CH782/783), located along the Rocky Reach of the Columbia River, includes lithic and faunal artifacts buried beneath volcanic tephra from Mt. Mazama (6,830 BP). Artifacts were inadvertently discovered in buried soils within a secondary alluvial terrace during construction of a pipeline to supply water to the Beebe Springs Fish Hatchery. This thesis stems from participation in original field work and includes the author’s own models of early land forms and site formation. The study reviews the construction monitoring and archaeological testing of both sites, and documents the archaeological data potential early occupations of the vicinity. The …

Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald

All Master's Theses

Captive chimpanzees (Pan troglodytes) engage with enrichment objects extensively during the daytime, yet relatively little is known regarding their use of available enrichment at night. This study examined night-time enrichment use in three adult chimpanzees at the Chimpanzee and Human Communication Institute. Every evening, the chimpanzees received a variety of enrichment objects. The objects belonged to one of nine categories. Night-vision video cameras recorded the chimpanzees’ night-time behaviors every Monday through Thursday from July 9 to August 9, 2012 (Carner et al., 2013). The present study used a focal animal, instantaneous sampling method (Martin & Bateson, 2007) to …

Tracing Ainu And Pre-Ainu Cultural Continuity Through Cladistic Analysis Of Faunal Assemblages, Christopher Lowry

All Master's Theses

Cladistics (Hennig 1950, 1965, 1966), a method for establishing evolutionary relationships, is used to compare faunal assemblages from Jōmon (14,000-500 BC; 14,000–2700 cal. BP), Epi-Jōmon (3rd – 7th century; 2700-1500 cal. BP), Satsumon (7th century - 13th century AD; ca. 1500-800 cal. BP), and Ainu (13th century AD – present) period components (Habu et al. 2011; Matsumura 2006; Ōnishi 2014; Weber et al. 2013) from sites in Central Hokkaido, Japan using Generalized Frequency Coding methods (Smith & Gutberlet 2001). Associations of site components follow geographic rather than temporal trends, showing similarities in animal use across these time periods but differentiated …

Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia

All Master's Theses

Enrichment is an aspect of captive husbandry that has been shown to positively impact animals’ well-being and can be designed to encourage species-typical behaviors, such as foraging and arboreality. Enrichment can include housing together multiple compatible species. Orangutans are sympatric with siamangs and agile and Bornean gibbons, so several zoos house these four Asian ape species in the same enclosure, in part, as social enrichment. In my study, I observed enrichment use and social interactions in a mixed-species enclosure at the Oregon Zoo, which housed two Sumatran (Pongo abelii) and two Bornean (P. pygmaeus) orangutans with …

Thermal And Behavioral Ecology Of The Mexican Beaded Lizard (Heloderma Horridum), Kerry Holcomb

All Master's Theses

Previous investigations in the field of biological thermoregulation have primarily focused on small organisms that inhabit ecosystems that are not as strongly seasonal as the tropical dry forests found along the Pacific Coast of Jalisco, Mexico. Small organisms have little or no appreciable thermal inertia, and thus, reach thermal equilibrium with their immediate surroundings relatively rapidly. In this investigation, we describe the behavioral and thermal ecology of the Mexican beaded lizard (Heloderma horridum), which commonly weighs more than 1kg. This large body size means that this species has significant thermal inertia, which, depending on the characteristics of the …

Tqm/Iso 9001 Implementation In Northern And Central Luzon State Universities, Patrick C. De Leon

Journal of Public Affairs and Development

This case study was conducted to investigate why and how the TQM/ISO 9001 programs were adopted in state universities in the Philippines such as Pangasinan State University, Nueva Ecija University of Science and Technology, and Central Luzon State University; what TQM and ISO 9001 meant to them; and what factors affected TQM/ISO 9001 implementation in their universities. The study found that TQM/ ISO 9001 programs were intended to streamline work processes and improve the quality of services. Implementation involved the hiring of a consultant, conducting trainings, preparing and using a QMS manual, organizing internal and external audits, and receiving ISO …

Fundamental Principles Of Tremor Propagation In The Upper Limb, Andrew D. Davidson, Steven Knight Charles

Faculty Publications

Although tremor is the most common movement disorder, there exist few effective tremor-suppressing devices, in part because the characteristics of tremor throughout the upper limb are unknown. To clarify, optimally suppressing tremor requires a knowledge of the mechanical origin, propagation, and distribution of tremor throughout the upper limb. Here we present the first systematic investigation of how tremor propagates between the shoulder, elbow, forearm, and wrist. We simulated tremor propagation using a linear, time-invariant, lumped-parameter model relating joint torques and the resulting joint displacements. The model focused on the seven main degrees of freedom from the shoulder to the wrist …

Individual Variation In Fear Behaviour, Rob Found

Animal Sentience

Individual variation in behaviour adds another layer of complexity to studies of animal responses to fear and risk, but when individual responses are consistent, and correlated with other behaviours, these patterns can provide a structure that furthers our understanding. I interpret Beauchamp’s review of vigilance and fear from the perspective of my own studies of elk personality. Wild elk responses to changing stimuli (benign or aversive) illustrate how personality is a key factor in explaining variation in vigilance and fear behavior. Personality even influences how wildlife can learn to assess risk and adjust their fear responses accordingly.

Conceptualizing The Neurobiology Of Non-Suicidal Self-Injury From The Perspective Of The Research Domain Criteria Project, Scott R. Braithwaite, Melinda Westlund Schreiner, Bonnie Klimes-Dougan, Erin D. Begnel, Kathryn R. Cullen

Faculty Publications

Non-suicidal self-injury (NSSI) commonly starts in adolescence and is associated with an array of negative outcomes. Neurobiological research investigating NSSI is in its early stages and most studies have examined this behavior within the context of specific diagnoses. However, the Research Domain Criteria (RDoC) initiative encourages researchers to examine brain-behavior relationships across diagnoses. This review on the neurobiology associated with NSSI is organized using the domains proposed by RDoC: Negative Valence, Positive Valence, Cognitive, Social Processes, and Arousal/Regulatory Systems. Evidence of neurobiological anomalies is found in each of these domains. We also propose future research directions, especially in regard to …

Sentience In Living Tissue, Alfredo Pereira Jr.

Animal Sentience

I agree with Woodruff’s concept of sentience but must disagree about what he proposes as the biological correlates of feeling. Based on the interpretation of brain function originally presented by Camilo Golgi, I assume that feelings are instantiated by hydro-ionic waves in living tissue. From this viewpoint, the anatomical, physiological and behavioural criteria of Woodruff would not be necessary to argue for sentience in fish.

Animal Models, Agendas And Sentience, Thomas Creson

Animal Sentience

Woodruff’s target article on teleost consciousness is a well-organized logical argument for considering the fish as a sentient being. This becomes more important for animal ethical discussion as the fish becomes a more important and legitimate animal model for investigating animal states and traits associated with higher levels of behavior such as learning and memory.

The Emotional Brain Of Fish, Sonia Rey Planellas

Animal Sentience

Woodruff (2017) analyzes structural homologies and functional equivalences between the brains of mammals and fish to understand where sentience and social cognition might reside in teleosts. He compares neuroanatomical, neurophysiological and behavioural correlates. I discuss current advances in the study of fish cognitive abilities and emotions, and advocate an evolutionary approach to the underlying basis of sentience in teleosts.

Nominalized Adverbs In Spanish: The Intriguing Case Of Detrás Mío And Its Cohorts, David Eddington

Faculty Publications

Instances of adverbs modified by adjectives (e.g. detrás mío, delante tuyo) were extracted from the Corpus del Español. The corpus analysis reveals that these constructions are attested in all 21 Spanish-speaking countries to varying degrees, but are most frequent in Argentina and Uruguay. Adjectives following the adverbs in questions are predominantly masculine; however, in Peninsular varieties feminine forms are quite common. Although alrededor and lado are both adverbs as well as masculine nouns, they are occasionally followed by feminine adjectives (e.g. al lado suya), which is arguably due to the use of the feminine in other constructions such as encima …

A Risk Assessment And Phylogenetic Approach, Culum Brown

Animal Sentience

The precautionary principal is often invoked when talking about the evidence of sentience in animals, largely because we can never be certain what any animal is thinking or feeling. Birch (2017) offers a preliminary framework for the use of the precautionary principal for animal sentience combining an epistemic rule with a decision rule. I extend this framework by adding an evolutionary phylogentic approach which spreads the burden of proof across broad taxonomic groups and a risk assessment component which magnifies the likely impact by the number of animals involved.

The “Precautionary Principle” – A Work In Progress, Shelley Adamo

Animal Sentience

The target article by Birch illustrates the practical difficulties with the “Animal Sentience Precautionary Principle” (ASPP) while presenting potential solutions. However, the ASPP will be difficult to use without guidelines detailing how evidence of sentience should be assessed. Moreover, extrapolating conclusions found for a single species to all species within an Order is problematic. Finally, I recommend that Birch demonstrate his ASPP framework using a controversial test case to help show how it could be used in real-world situations.

Precaution, Proportionality And Proper Commitments, Colin Klein

Animal Sentience

Birch’s extension of the precautionary principle (PP) is plausible but raises issues about how proportionality ought to be incorporated into law. Following Steel (2013), I suggest that the PP is best considered as a meta-norm, and as such any resulting laws are likely to lack the fineness of grain that we would hope to achieve. To fill the gap, I suggest a parallel with the ethics of studying looted artifacts.

Not Statistically Significant, But Still Scientific, Rachael L. Brown

Animal Sentience

Birch’s formulation is persuasive but not nuanced enough to capture at least one situation where it is reasonable to invoke the precautionary principle (PP): when we have multiple, weak, but convergent, lines of evidence that a species is sentient, but no statistically significant evidence of a single credible indicator of sentience within the order as required by BAR. I respond to the worry that if we include such cases in our framework for applying the PP, we open ourselves to the charge of being “unscientific.”

Corticosteroid-Laba Inhalers Increase Phonation Threshold Pressure (Ptp) And Flow (Ptf) In Rabbits, Christopher Dromey, Kristine Tanner, Heidi J. Robison, Maya Elena Stevens, Ray M. Merrill, Julie Barkmeier-Kraemer, Ben Christensen

Objectives: This study examined the effects of a combination corticosteroid plus long-acting beta2-adrenergic agonist inhaler (IC) on rabbit phonation. Methods: White New Zealand male rabbits were assigned randomly to experimental and control groups (n = 11 per group). The experimental group received twice-daily doses of Advair HFA™ (fluticasone propionate 45 mcg and salmeterol 21 mcg) via a veterinary facemask with 1-way valve and spacer; the control group received aerosolized saline. After 8 weeks, animals were euthanized, larynges excised, frozen, and subsequently thawed and mounted on a standard bench apparatus. Phonation was elicited during 15 successive trials, and phonation threshold pressure …

The Effect Of Loving-Kindness Meditation On Physiological And Psychological Reactions To Violent Stimuli, Joseph A. Garcia

College of Graduate Studies: Theses & Dissertations

In the past, meditation research has focused primarily on mindfulness meditation, but little research has examined Loving-Kindness Meditation (LKM). LKM may be an important addition to treatment or preventative programs for people at risk of exposure to violence or aggression in their lives or work. The current research aims to add to the currently growing body of literature concerning LKM and compassion based meditation practices. The researchers sought to determine if a 12-week course in LKM would have any effect on galvanic skin response (GSR) and heart rate in beats per minute (BPM) during the presentation of a video containing …

Assessing The Genetic Status And Factors Leading To The Decline Of The Roanoke Bass (Ambloplites Cavifrons), Jackman C. Eschenroeder

College of Graduate Studies: Theses & Dissertations

Although numerous factors have led to the staggering declines in freshwater biodiversity throughout the United States and the world, habitat alteration and introduced species pose some of the greatest challenges to conservation efforts. Learning more about how these two factors lead to the decline of an endemic organism could help prevent the future loss of unique species and the premature conclusion of evolutionary trajectories. Roanoke bass (Ambloplites cavifrons) is a sport fish endemic to portions of the Roanoke, Chowan, Tar, and Neuse river basins of North Carolina and Virginia. This species has been in decline for many years, …

Goal Orientation, Motivational Climate, And Exercise As Predictors Of Eating Disorder Risk Factors Among College Students, Carly Wahl

College of Graduate Studies: Theses & Dissertations

College is a transition period in a young adult’s life in which eating disorder symptomology is especially prevalent. Additionally, motivation-based factors such as goal orientation and motivational climate can influence these eating disorder-like behaviors, especially in a physical activity setting. The present study aimed to examine how goal orientation, motivational climate, and exercise could be used to predict a college students’ eating disorder symptomology. Participants included 276 college-aged males and females from a university in the southeastern United States. These participants had experience using the university recreation activity center and were recruited from a required healthful living course. Each participant …

Reducing Substance Abuse Stigma In Employment Application, Timothy W. Curran

College of Graduate Studies: Theses & Dissertations

A history of substance use and having a history of legal charges can be a barrier to employment. Available research shows individuals with a criminal history of substance related charges have greater difficulty obtaining employment due to the presence of substance abuse stigma and criminal history stigma. Research also shows that employers with higher levels of fundamentalism and conservativism are more likely to negatively evaluate applicants with a criminal history of substance charges. Furthermore, available research demonstrates employers in rural areas are more likely to deny employment to an individual with a legal history of substance charges based upon higher …

A Markov Decision Process Approach To Adaptive Contact Strategies, Artur Grygorian

College of Graduate Studies: Theses & Dissertations

In the field of survey methodology, optimizing contact strategies helps organizations increase response rates using their allocated budget. Markov Decision Processes (MDP) are widely used to model decision-making strategies in situations where the outcomes have a random component. In this research, we use MDPs and adaptive sampling techniques to construct a strategy that, based on target audience characteristics, suggests the best contact policy. The data we use comes from the First Destination Survey conducted by the Office of Career Services at Georgia Southern University. The constructed model is quite flexible and can be used by other organizations to optimize their …

Investigating Individual Pathways To Recovery, Mackenzie R. Mcbride

College of Graduate Studies: Theses & Dissertations

Drug use is most prevalent among young adults between ages 18 and 24; this is just one factor that contributes to the high rates of substance use on college campuses. Collegiate recovery programs (CRPs) have been growing in number, awakening the “youth in recovery” movement. This paper presents literature on various tools and elements of recovery, with a focus on CRPs and their significance. This study aims to fill the knowledge gap by examining individual pathways to recovery and learning about the characteristics of students participating in CRPs, including their life events and decisions to seek treatment. Semi-structured interviews were …

Psychopathy And The Effect Of Imitation On Empathetic Pain, Emily N. Lasko

College of Graduate Studies: Theses & Dissertations

Psychopathy is a disorder largely characterized by a marked deficit in empathy, however, the specificity and extent of the deficit is currently unclear. While it has been well-established in the literature that individuals higher in psychopathy tend to have intact Theory of Mind abilities and exhibit a deficient ability for affective empathy (Blair, 2005), the contribution of motor empathy to these abilities, particularly in regard to empathy for pain, has yet to be experimentally examined. Additionally, the possibility of imitation increasing motor empathic abilities has not been tested in this capacity. The goal of the current study was to further …

Electroencephalographic Signal Processing And Classification Techniques For Noninvasive Motor Imagery Based Brain Computer Interface, Md Erfanul Alam

College of Graduate Studies: Theses & Dissertations

In motor imagery (MI) based brain-computer interface (BCI), success depends on reliable processing of the noisy, non-linear, and non-stationary brain activity signals for extraction of features and effective classification of MI activity as well as translation to the corresponding intended actions. In this study, signal processing and classification techniques are presented for electroencephalogram (EEG) signals for motor imagery based brain-computer interface. EEG signals have been acquired placing the electrodes following the international 10-20 system. The acquired signals have been pre-processed removing artifacts using empirical mode decomposition (EMD) and two extended versions of EMD, ensemble empirical mode decomposition (EEMD), and multivariate …

Romantic Interest Selection From An Imago Relationship Therapy Perspective, Lauren O. Patterson

College of Graduate Studies: Theses & Dissertations

Imago Relationship Therapy (IRT) is a model of couples therapy that is not empirically validated (Jakubowski et al., 2004). IRT proposes that individuals select Romantic Interests (Interests) that are similar to their Childhood Caregivers (Caregivers) in an effort to heal childhood wounding (Hendrix, 1988). The current study sought to evaluate the IRT proposition of romantic interest selection by evaluating patterns in romantic interest selection, particularly the relationship between Caregiver and Interest personality characteristics, adult attachment dimensions, gender, and geographical location of origin. In addition, the study considers similarities in participant narratives of positive and negative experiences with Caregivers and Interests. …
