Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien

Independent Study Project (ISP) Collection

This study examines the use of sub-tidal open-bottom, rocky, and seagreass habitats by the Siganus genus (herbivores), Gerres genus (benthivores), and planktivores in the Hinchinbrook Channel Estuary in Queensland, Australia. The Hinchinbrook Channel Estuary, a tropical estuary cutting between Hinchinbrook Island and the Australian mainland, is surrounded primarily by mangroves. Its sub-tidal habitats are largely unexplored due to factors such as low visibility and the presence of estuarine crocodiles. In this study, I reviewed 699 underwater videos collected by James Cook University PhD candidate Michael Bradley in order to analyze feeding and movement behavior of pre-identified fish.

The Effects Of Environmental Prompts On Stair Usage, Lori Andersen, Tim Bungum, Sheniz Moonie Phd

Nevada Journal of Public Health

Experts have advocated exercise with little success, and have turned to encouraging physical activity by incorporating it into daily activities such as taking the stairs over elevators. Much literature exists suggesting that environmental prompts can encourage the use of stairs and literature has established that some messages may be more effective than others. This study aimed to assess the effects of selected signage prompts on stair usage. Methods: Stair and elevator use were monitored in three, two-story buildings. One building served as a control, while a fitness message was placed in another building, and the final building received a weight …

Development Of Culturing Methods For Native Mayfly Taxa For Use In Laboratory Toxicity Testing, Kevin Nicholas Rowsey

Theses, Dissertations and Capstones

Salinity is increasing in freshwaters throughout the world due to anthropogenic impacts with the implication of the increases to biological communities only now being realized. Declining mayfly populations in Appalachian streams have generated increased interest in elevated dissolved solids in that region and their effect on benthic macroinvertebrates, particularly the sensitive Ephemeroptera taxa. Field and laboratory evaluations have indicated high sensitivity of mayflies to elevated dissolved solids. The research described herein is part of an ongoing effort to provide opportunity for toxicity testing with native mayflies in the laboratory. A successful endeavor would establish mayfly sensitivity to total dissolved solids …

Repeated Effects Of The Neurotensin Receptor Agonist Pd149163 In Three Animal Tests Of Antipsychotic Activity: Assessing For Tolerance And Cross-Tolerance To Clozapine, Shinnyi Chou, Collin Davis, Sean Jones, Ming Li

Department of Psychology: Faculty Publications

Neurotensin is an endogenous neuropeptide closely associated with the mesolimbic dopaminergic system and shown to possess antipsychotic-like effects. In particular, acute neurotensin receptor activation can inhibit conditioned avoidance response (CAR), attenuate phencyclidine (PCP)-induced prepulse inhibition (PPI) disruptions, and reverse PCP-induced hyperlocomotion. However, few studies have examined the long term effects of repeated neurotensin receptor activation and results are inconsistent. Since clinical administration of antipsychotic therapy often requires a prolonged treatment schedule, here we assessed the effects of repeated activation of neurotensin receptors using an NTS1 receptor selective agonist, PD149163, in 3 behavioral tests of antipsychotic activity. We also investigated whether …

Approximation Of Fire-Return Intervals With Point Samples In The Southern Range Of The Coast Redwood Forest, California, Usa, Gregory Jones, Will Russell

Faculty Publications, Environmental Studies

A legacy of past fires is evident in the form of blackened basal hollows found throughout the southern range of the coast redwood (Sequoia sempervirens [D. Don] Endl.) forest.  A deeper look reveals cambial scars dating back centuries, telling a story of low- to moderate-intensity fires that burned periodically across California’s Central Coast bioregion.  While attempts have been made to reconstruct the fire history of this forest type, estimates of the fire-return interval vary widely, and the relationship of the fire-return interval to varying cultural influences is not fully understood.  We analyzed 373 fire scars from 70 cross-sections removed from …

Utilization Of Placebo Response In Double-Blind Psychopharmacological Studies, Contextual Perspective, Margarita Olegovna Ashirova

Antioch University Dissertations & Theses

Placebo response has been an elusive phenomenon in the fields of medicine, medical research, and psychology. Even though it has been heavily utilized as a comparator treatment in double-blind psychopharmacological studies, the reliable definition and consistent understanding of placebo response are missing. In this contextual exploration, I outlined the state of current placebo response research and variable rates of placebo response reported in double-blind studies. I identified the gap in the literature—lack of consistent understanding of placebo response—that has led to a waste of resources by the psychopharmacological research industry. Further, I compared and contrasted the current inconsistent Western medical …

The purpose of this study was to examine the history of the Ford Motor Company’s impact upon the Ramapo Watershed of New York and New Jersey, as well as upon the Ramapough Munsi Nation, an indigenous population living there. In a 25 year span the automaker produced a record number of vehicles and dumped a massive amount of lead paint, leaving behind a toxic legacy that continues to plaque the area and its residents. The Ramapough people are not unlike many native nations living in the United States who have experienced industrial excess. This study examines the mindset that allows …

Impacts Of Land-Cover Change And High Rainfall On Soil Erosion Among Three Farms In Cerro Punta, Chiriquí, Panamá., Madeline Happ

Independent Study Project (ISP) Collection

Soil erosion is a key source leading to the depletion of Earth’s natural resources. Beginning with deforestation, soils are stripped of their rich vegetation cover, leaving them vulnerable to wind, water, and sometimes total exhaustion. One of the major causes of deforestation, if not the primary cause, is for agricultural purposes. Extensive agricultural fields, steep slopes, and heavy rains characterize the highlands of Chiriquí; thus, the land displays potential for severe loss of soil. This paper illustrates and discusses the extent of soil erosion in Cerro Punta, Chiriquí, specifically considering the steep terrains and very wet environment that impact the …

A Quantitative Analysis Of The Value-Enhancing Effects Of Nicotine, Bupropion, And Varenicline In Male And Female Rats, Scott Barrett

Department of Psychology: Dissertations, Theses, and Student Research

Smoking and tobacco dependence are serious health concerns in the United States and globally. Reward via the pharmacological effects of nicotine are believed to be the principal motivating factor that drive tobacco dependence. Research reveals differences in sensitivity between males and females to the motivational effects of nicotine in tobacco use. Enhancement of reinforcement value of non-nicotine rewards contributes to overall nicotine reward. Similar value-enhancing effects have been observed by the two most commonly prescribed smoking cessation aids, bupropion and varenicline. The present dissertation investigated the value-enhancing effects of nicotine, bupropion and varenicline in both male and female rats using …

Parental Factors That Influence Swimming In Children And Adolescents, Jennifer Pharr, Carol C. Irwin, Richard L. Irwin

Environmental & Global Health Faculty Research

Swimming can be an important source of physical activity across the life-span. Researchers have found that parents influence physical activity behaviors of their children. The purpose of this study was to determine what parental factors influenced the number of days that children swam. Survey respondents (n = 1,909) from six cities across the United States were surveyed at local YMCAs. Children were found to swim significantly more if their parents encouraged them to swim, members of the family knew how to swim and swam with them, or their parents were not afraid of the children drowning or afraid of …

Role Of Group Ii Metabotropic Glutamate Receptor Subtype 2 (Mglur2) In Appetitive And Consummatory Aspects Of Ethanol Reinforcement, Kyle Allyson Windisch

Open Access Dissertations

Background: Group II metabotropic glutamate receptors (mGluR2/3) are predominately presynaptically located G_i/o coupled receptors that are highly expressed in the cortex, nucleus accumbens, amygdala, and hippocampus. Previous studies suggest that group II mGluRs are involved in regulating ethanol (EtOH) consumption and seeking following extinction (Backstrom and Hyytia, 2005; Kufahl, et al., 2011). The sipper tube model, which allows for procedural separation of seeking and consumption, was used to further clarify the role of mGluR2/3 in EtOH-seeking and consumption. The non-selective group II mGluR agonist LY379268 (LY37) and selective mGluR2 positive allosteric modulator (PAM) BINA were used to determine the …

Light Pollution Research Through Citizen Science, John Kanemoto

STAR Program Research Presentations

Light pollution (LP) can disrupt and/or degrade the health of all living things, as well as, their environments. The goal of my research at the NOAO was to check the accuracy of the citizen science LP reporting systems entitled: Globe at Night (GaN), Dark Sky Meter (DSM), and Loss of the Night (LoN). On the GaN webpage, the darkness of the night sky (DotNS) is reported by selecting a magnitude chart. Each magnitude chart has a different density/number of stars around a specific constellation. The greater number of stars implies a darker night sky. Within the DSM iPhone application, a …

Considering Sport Participation As A Source For Physical Activity Among Adolescents, Jennifer Pharr, Nancy L. Lough

Environmental & Global Health Faculty Research

BACKGROUND:

Studies have shown participation in sport is lower among girls than boys, decreases as students matriculate through high school, is lowest among Black and Hispanic girls and has a positive relationship with SES. With sport recognized as a contributor to physical activity and health in adolescents, consideration of diminishing rates of participation appears warranted. The purpose of this study was to identify patterns related to differences in self-reported sport participation between genders, ethnic groups, grades and SES.

METHODS:

This study was a cross-sectional, secondary analysis of data collected for a sport interest survey. All students in grades 8-11 attending …

Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores

Honors College Theses

The human has caused a far greater impact on the planet's biodiversity than any other species in existence, due to the impact of population, afflluence, and technology. This thesis will argue the importance of biological diversity and how affluent populations are reducing biodiversity through the consumption of meat, electronics, and motor vehicles. Aldo Leopold's "The Land Ethic" and Herman Daly's "The Impossibility Theorem", among others, create a rubric evaluating human activities and provide alternative views on economic impossibilities. Consumption is reviewed from an ecocentric perspective, a holistic outlook placing emphasis on the ecosystem. The reader will become cognizant of their …

Bioplastics: Reinventing Conventional Plastic Production And The Future Of Biodegradable Materials, Ruby Roca

2014 Student Theses

The use of plastic is prevalent in our society due to the increasing amount of new products entering the market that need some form of packaging that is solid enough yet disposable. From everything to yogurt containers to diapers, plastic containers are a large part of our society’s consumption culture and often goes unnoticed. However, people point to plastic water bottles and containers as the only culprit, and often times forget that almost all packaging contains some form of plastic. For my thesis I want to examine how the use of plastics has increased waste material, considering that it takes …

Federal V. State Effectiveness: An Analysis Of The Endangered Species Act And Current Potential Attempts At Reform, Nicholas Primo

Pepperdine Policy Review

In November 2013, several Congressional leaders drafted a new bill to reform the Endangered Species Act of 1973 (ESA). While the Endangered Species Management Self-Determination Act (ESMSDA) was the first major attempt at updating the crucial U.S. environmental policy in decades, it also inflamed environmentalist defenders of the original bill. More importantly, it raised several questions as to whether state or federal-oriented approaches to endangered species protection and environmental policy more broadly is ultimately more effective. This article analyzes the original 1973 ESA, followed by an analysis of the ESMSDA currently being considered. It will discuss the various strengths and …

Message Matters: Application Of The Theory Of Planned Behavior To Increase Household Hazardous Waste Program Participation, Amy Dyer Cabaniss

Antioch University Dissertations & Theses

Removing household hazardous waste (HHW) from the municipal solid waste stream is important to protect health, safety and the environment. Communities across the U.S. separate HHW from regular trash for disposal with hazardous waste, however nationally, participation rates are low with only five to ten percent of households estimated to participate in any given collection. This two-part study used the Theory of Planned Behavior (TPB) to understand individuals’ beliefs and attitudes toward HHW collections, and to develop a print message intervention to increase participation. In Study 1, respondents (N = 983) completed a survey administered to homeowners in the Connecticut …

Repeated Asenapine Treatment Produces A Sensitization Effect In Two Preclinical Tests Of Antipsychotic Activity, Rongyin Qin, Yingzhu Chen, Ming Li

Department of Psychology: Faculty Publications

Among several commonly used atypical antipsychotic drugs, olanzapine and risperidone cause a sensitization effect in the conditioned avoidance response (CAR) and phencyclidine (PCP)- induced hyperlocomotion paradigms – two well established animal tests of antipsychotic drugs, whereas clozapine causes a tolerance effect. Asenapine is a novel antipsychotic drug recently approved for the treatment of schizophrenia and manic disorders. It shares several receptor binding sites and behavioral features with other atypical antipsychotic drugs. However, it is not clear what type of repeated effect (sensitization or tolerance) asenapine would induce, and whether such an effect is transferrable to other atypicals. In this study, …

Accommodations For Patients With Disabilities In Primary Care: A Mixed Methods Study Of Practice Administrators, Jennifer Renee Pharr

Environmental & Global Health Faculty Research

Structural barriers that limit access to health care services for people with disabilities have been identified through qualitative studies; however, little is known about how patients with disabilities are accommodated in the clinical setting when a structural barrier is encountered. The purpose of this study was to identify how primary care medical practices in the United States accommodated people with disabilities when a barrier to service is encountered. Primary care practice administrators from the medical management organization were identified through the organization’s website. Sixty-three administrators from across the US participated in this study. Practice administrators reported that patients were examined …

Selected Neuropharmacology Of Resurgence, Adam D. Pyszczynski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reemergence of problem behavior (i.e., relapse) is a key concern in most behavioral interventions. Resurgence refers to the reappearance of a previously rewarded behavior when reward for an alternative behavior is also discontinued. It is especially relevant to the reappearance of problem behavior because many behavioral interventions discontinue reward for aberrant behavior while simultaneously rewarding an appropriate response.

Understanding the underlying neuropharmacology of behavioral phenomena such as resurgence is important because it helps elucidate the neural processes at the root of such behavior, and also has implications for pharmacotherapies. Existing information about the neuropharmacology of resurgence is scarce, but …

A Need For Green: An Approach For Motivating Environmentally Sustainable Practices At The University Of Rhode Island, Alyssa Mason, Mary Vidal

Senior Honors Projects

“Never underestimate the power of a few committed people to change the world. Indeed, it is the only thing that ever has." -Margaret Meade

Colin Beavan’s No Impact Man details his yearlong experiment to live without creating any environmental impact. As sophomores we were inspired by Beavan’s journey but also skeptical of living a completely no-impact lifestyle as college-students. Although we were motivated to try to live sustainably, our efforts were dormant until our junior year. That year we decided that we would attempt to live up to the standards set forth by Beavan--understanding that some practices would be harder …

The Effects Of Selected Drugs On The Memory Recall Of Sleep Deprived Mice, Jenn Pauldurai

Capstone Research Projects

Humans often make use of the neurotransmission altering effects of drugs such as caffeine, ephedrine, and ethanol. These drugs induce changes in memory and learning ability, specifically when used for sleep deprivation. English white mice (Mus musculus) have been shown to exhibit similar cognitive changes when administered drugs while sleep deprived. A sample of 20 mice was divided into three experimental groups (each group receiving a different drug) and one control group. Maze-testing demonstrated that mice performance decreased with sleep deprivation (Treatment-1) but all groups returned to baseline performance when injected (IP) with selected drugs (Treatment-2), regardless of …

Accessible Medical Equipment For Patients With Disabilities In Primary Care Clinics: Why Is It Lacking?, Jennifer Renee Pharr

Environmental & Global Health Faculty Research

Background: Previous research has identified inaccessible medical equipment as a barrier to health care services encountered by people with disabilities. However, no research has been conducted to understand why medical practices lack accessible equipment.

Objectives/Hypothesis: The purpose of this study was to examine practice administrators’ knowledge of accessible medical equipment and cost of accessible medical equipment to understand why medical practices lack such equipment. Hypotheses were: 1) Practice administrators lacked knowledge about accessible medical equipment and 2) The cost of accessible medical equipment was too great compared to standard equipment for the clinic.

Methods: This study was a mixed methods …

Atrazine And Nitrate In Public Drinking Water Supplies And Non-Hodgkin Lymphoma In Nebraska, Usa, Martha G. Rhoades, Jane L. Meza, Cheryl L. Beseler, Patrick J. Shea, Andy Kahle, Julie M. Vose, Kent M. Eskridge, Roy F. Spalding

School of Natural Resources: Faculty Publications

A secondary analysis of 1999–2002 Nebraska case-control data was conducted to assess the risk of non-Hodgkin lymphoma (NHL) associated with exposure to nitrate- and atrazine-contaminated drinking water. Water chemistry data were collected and weighted by well contribution and proximity of residence to water supply, followed by logistic regression to determine odds ratios (OR) and 95% confidence intervals (CI). We found no association between NHL risk and exposure to drinking water containing atrazine or nitrate alone. Risk associated with the interaction of nitrate and atrazine in drinking water was elevated (OR, 2.5; CI, 1.0–6.2). Risk of indolent B-cell lymphoma was higher …
