Species Distribution Modeling For Arid Adapted Habitat Specialists In Zion National Park, Sam Driver, Chris M. Schalk, Daniel Unger, David Kulhavy

Electronic Theses and Dissertations

The Arizona toad (Anaxyrus microscaphus) and Jones’ waxy dogbane (Cycladenia humilis var. jonesii) are habitat specialists with historical ranges in the desert southwest and specifically, Zion National Park (ZION). The machine learning method, MaxEnt, constructed species distribution models (SDMs) in ZION for the two study species at 30 m and 900 m spatial resolutions using climate, topographic, and remotely sensed data. Additionally, 900 m forecasting models were constructed to observe the shifts in suitable habitat for the years 2050 and 2070, based off two representative concentration pathway scenarios. Results indicate promising predictive power for both high …

An Economic Analysis Of Using Retired Vessels To Create Artificial Reefs In Costa Rica, Josué González

Electronic Theses and Dissertations

ABSTRACT

The Republic of Costa Rica is a Central American country with only 0.03% of the world’s landmass, but 5% of the world’s biodiversity, making it a leading ecotourism destination. Ecotourism is one of the main sources of revenue for the country, but the degradation of coastal reefs has resulted in a significant loss of financial income for developing areas. As a result, many of these areas are searching for methods to revert the degradation of coral reefs.

Artificial reefs play an important ecological role in marine ecosystems due to their complexity and size. They help in the development of …

University Course Evaluations: A Study Of The Influence Of Faculty, Student, And Course Variables, Tyesha De’Shuan Stewart

Electronic Theses and Dissertations

Course evaluations impact faculty’ annual evaluations and have become somewhat controversial, yet course evaluations in faculty evaluations persist as a common practice across universities. While many scholars find this success-based tool effective in assessing teaching effectiveness, others question the validity and reliability of this measurement and are opposed to using this tool as a mean of determining faculty members’ success. The purpose of this study is to provide a more in-depth examination of course evaluations by analyzing faculty, student, and course variables. Analyses were performed to address the following research question: “To what degree do faculty gender, faculty race, faculty …

Exploring Visual Attention Patterns Of Adults With Reported Adhd, Without Adhd, And Those With Malingering Adhd Symptoms, Roselia Juan

Electronic Theses and Dissertations

Noncredible performance and the intentional faking of symptoms during psychological evaluations have been observed in those seeking to obtain personal benefits. Cognitive deficits, such as impairments in attention are common in mental health settings and many seek an evaluation to rule out an attention-deficit/hyperactivity disorder. Previous literature establishes a base rate for malingering to be between 22-47% in adult ADHD evaluations (Sullivan, 2007; Suhr et al., 2008; Marshall et al., 2010). However, those faking or exaggerating ADHD can go unnoticed on self-report measures. There are limited studies that have identified methods that can specifically discriminate true ADHD from malingered ADHD. …

Land Suitability Analysis For Windfarm Development In Texas, Robert Laszlo Milecz

Electronic Theses and Dissertations

Due to the negative impact on the environment of conventional electric power generation methods, especially coal and oil-fired generating plants, wind power as an alternative for sustainable energy has received more attention in recent years. The purpose of this project was to apply Geographic Information System (GIS), integrated with Multi Criteria Decision Making (MCDM), for identifying suitable areas for wind turbine applications in Texas. Factors taken into consideration included socioeconomic criteria such as distance to highways, proximity to airports and urban areas, localized environmental criteria such as terrain slope and distance to rivers, affected waterbodies, and wildlife management areas. Also …

An Eeg Study On Loneliness And Recognition Memory, Carmen Jia Wen Chek

Electronic Theses and Dissertations

Loneliness, the perception of unmet social needs, has been shown to relate to recollection-based recognition deficits, but the relationship between loneliness and recognition memory (i.e., recollection and familiarity) has not been thoroughly examined. The current study hypothesized that more lonely individuals would have lower recognition memory performance, specifically recollection, with smaller ERP parietal old-new effects than less lonely individuals. Forty participants, grouped into less (n = 13) and more (n = 9) lonely groups based on their R-UCLA responses, completed an associative memory task. EEG was used to assess recognition memory effects. Results showed no significant difference in …

The Effects Of Self-Regulation Depletion And Race On The Willingness To Interact With Individuals With Mental Illness, Kenocha K. Epperson

Electronic Theses and Dissertations

Although the discrimination that Black individuals encounter is unique, it is similar in some ways to the discrimination experienced by individuals with mental illness (Corrigan & Wassel, 2008; Follmer & Jones, 2018; Jackson & Stewart, 2003). Research has found that these kinds of stigma can be overridden (Baumeister et al., 1998), but doing so requires self-regulation, which can be depleted (Gailliot et al., 2007). Because stigma exists against both Black individuals and those with mental illness, and because self-regulation is necessary to override those stigmas, the purpose of this project was to examine the relationships to which Black participants would …

An Investigation Of Anxiety- And Depression-Like Behavior After Head Trauma In Mice, Sean K. Payne

Electronic Theses and Dissertations

Every year around 2 million people in the United States (US) suffer a traumatic brain injury. Those people are often at a higher risk of post-TBI psychiatric illness, like anxiety and depression. Animal models of TBI are a useful way to measure such psychiatric illnesses in a pre-clinical setting. There were two purposes of this study: the first being to test the modified Marmarou TBI model, and second to investigate anxiety- and depression-like symptoms in C57Bl6/J mice following a TBI. The modified Marmarou model used different weights (95g, 30g, & sham) to see how severity affected the manifestation of anxiety-like …

Cover-Copy-Compare: A Literature Review, Juan Chen

Electronic Theses and Dissertations

Cover-copy-compare (CCC) is an evidence-based math intervention strategy that can be used to help to build math fact accuracy and fluency. This literature review aims to examine different modifications of CCC, the effectiveness of CCC in helping students with disabilities, and identifying targeted computational skills. Discussion will also focus on the generalizability of CCC. After using predetermined inclusion and exclusion criteria, thirty-nine articles were identified as relevant to this study. The results indicate that CCC demonstrated efficacy among students with Specific Learning Disability (SLD), Attention Deficit/Hyperactive Disorder, and emotional and behavioral disorders. There is no current evidence that CCC works …

The Effects Of Ego Depletion And Deception On Thin-Slicing Accuracy, Jessica C. Lowe

Electronic Theses and Dissertations

This study was designed to examine the effects of ego depletion and deception on thin slicing. Experiment 1 examined whether participants could identify a video that contained a lie at an accuracy rate better-than-chance. Fifty-five percent of participants selected the deception video, which provided support that the videos were distinguishable. Experiment 2 assessed whether ego depletion and deception could decrease thin-slicing accuracy. The main effect of deception on deception accuracy was significant, such that participants in the deception condition had lower deception accuracy than participants in the no-deception condition. The main effect of depletion and the interaction of depletion and …
