A Mixed Methods Approach To Study The Effects Of A Naturalist Summer Program On The Perceptions Of African American Children About Nature, Kendrick Buford

Dissertations

African Americans have been reported to have a more negative outlook on nature than people of other races. Much work has been done to explain this phenomenon through the lenses of social and environmental justice. However, most of this information pertains to adults, and little to no exploration has been done to understand how children could be affected. This lack of information creates a novel research topic. This study addressed the problem using a mixed method analysis to better understand both the narrative of the children and any generalizable conclusions to better understand their attitudes in a summer program titled …

Suspended Sediment And Particulate Matter Transport In Mississippi Sound And Bight Assessed With Physical Modeling, Remote Sensing And In Situ Measurements, Stephan O'Brien

Dissertations

Tidal passes between Mississippi Sound (MS Sound) and Mississippi Bight (MS Bight) act as a transport pathway for the exchange of estuarine discharge and suspended particulate matter. A better understanding of sediment and particulate matter exchange can provide insights into turbidity, nutrient supply and aquatic ecosystem health for the region. This work examined the effects of different forcing factors (e.g. wind and tides) on the advection of suspended sediments and particulate matter in the study area. Fieldwork included particle size distribution, Acoustic Doppler Current Profiler (ADCP) and conductivity-temperature-depth measurements in the MS Sound and MS Bight from summer 2015 through …

Necessary And Sufficient: Examining The Role Of Attachment Trauma And Psychological Maltreatment As Primary Etiological Factors In The Development Of Borderline Personality Disorder, Chacy Agnello

Dissertations

Current widely-accepted conceptualizations regarding borderline personality disorder (BPD) profess that trauma is not required in the etiology of BPD and place a significant focus on biological predispositions. This review sought to evaluate the current paradigms regarding BPD and examine whether trauma may be the most significant contributing factor in the development of BPD. Studies on developmental trauma (including psychological maltreatment) and attachment were examined. These studies appear to strongly support the idea that when disrupted attachment and psychological maltreatment are taken into consideration, trauma does appear to be both necessary and sufficient as primary etiological factors in the development of …

The Development Of Socio-Sexual Behavior In Beluga Whales (Delphinapterus Leucas), Malin K. Lilley

Dissertations

The reproductive success of the beluga whale is critical for a species facing extinction in its endangered Cook Inlet, Alaska population. To date, little is known about the mating behavior of these whales in wild populations. On the other hand, observations of beluga whales in human care allow researchers to better understand many aspects of their daily lives and life histories that are difficult to assess in wild populations. Thus far, a catalog of socio-sexual behavior has been established based on observations of belugas; however, the developmental trajectory of socio-sexual behavior is not well-understood. The present study explored how socio-sexual …

Environmental-Based Experiential Learning Activities And Its Influence On Students’ Knowledge, Critical Thinking, Attitude Towards The Environment, And Career Aspirations, Veshell Lewis

Dissertations

Modern advancements in industrialization and globalization are thought to be responsible for the present ecological issues facing the world (Sumen, 2016). Many countries, including the United States, emphasize the importance of increasing environmental literacy within the community and schools (Roth, 1992; Scholz, 2011; Sumen, 2016). It has been suggested that environmental education be taught at all educational levels to increase environmental literacy (Sumen, 2016). The implementation of environmental-based experiential education within the traditional curriculum has proven successful for various educational institutions. Therefore, the implementation of environmental-based experiential learning activities in Mississippi educational institutions may contribute to the increase of scientifically …

Bottlenose Dolphin (Tursiops Truncatus) Vocal Responses To Sonar And Spectrally Pink Background Noise, Maria Zapetis

Dissertations

As human populations rise, the level of man-made noise increases globally. Naval sonar and boat traffic are underwater sound sources of particular concern to marine mammal welfare. To better understand the impact of these noise increases on cetaceans, studies can explore animals’ behavioral changes in response to noise. Studies have investigated the ‘dose-response’ relationship between the received sound pressure level of sonar signals and the behavior of cetaceans in the wild, but exposure studies in controlled environments are limited. The studies in this dissertation examined bottlenose dolphin vocal modifications during various experimental noise treatments. Acoustic recordings previously obtained for bottlenose …

An Exploration Of Staff Training Practices Specific To The Prevention Of Staff-To-Student Sexual Misconduct In General And Special Education, Mary Kirsten Lintz

Dissertations

A United States Department of Education commissioned study found that 10% of kindergarten–12 grade students are victims of staff-to-student sexual misconduct (Shakeshaft, 2004; U.S. Department of Education, n.da). A primary recommendation from that study was that districts provide staff training specific to the prevention of staff-to-student sexual misconduct. However, despite strong and repeated recommendations that all schools include annual staff training that specifically addresses the issue of staff-to-student sexual misconduct (Caldas & Bensy, 2014; Krohn, 2014; Mainella, 2015; Shakeshaft, 2004; U.S. Department of Education, 2008), a majority of districts nationwide have been slow to include this topic in their district …

A Multifaceted Approach To Address Variation In Cannabis Sativa, Anna Louise Schwabe

Dissertations

For thousands of years, humans have cultivated and dispersed Cannabis sativa L. across the globe. Although Cannabis has been largely illegal worldwide for decades, public perceptions and attitudes are changing. Increasing interest in potential Cannabis usage worldwide and nationwide is leading to less restrictions to make way for an expanding and lucrative industry with numerous applications. Although only one species is formally recognized in the Cannabis genus, thousands of years of artificial selection for diverse phenotypes and uses have resulted in two major usage groups; hemp-types which are defined worldwide as having very low levels of THC (< 1.0%), and drug-types which exceed a specified level of THC that varies among nations. The drug-type category includes three commonly used subcategories including Sativa, Indica and Hybrid types, and newly developed high CBD varieties that have more THC than hemp-types but are not bred for high THC. The quality of federally produced Cannabis for medical studies in the U.S. has recently been brought into question, and we included samples to determine the genetic relationship to these groups. Phenotypic variation in Cannabis gives rise to commonly referenced categories, but sources of variation are unclear and understudied. Phenotypes are observable characteristics that results from a combination of both genotype and the environment. The preferred method of propagation for Cannabis is cloning, and therefore variation within varietals should be from differences in environmental factors. Ten microsatellite markers were developed de-novo to investigate four aims: (1) genetic variation within strains, (2) genetic relationships among the common categories, (3) if genetic variation is detectable through olfactory sensation, and (4) how genetic variation is reflected in phytochemical levels. This dissertation includes four manuscript chapters representing each aim and uses a genetic basis for a multifaceted approach to investigate variation in Cannabis sativa. Substantial genetic variation was found within strains from obtained from different facilities. Genetic divergence between hemp and drug-types was genetically supported, but the Sativa, Indica, and Hybrid subcategories were not genetically well defined. The high CBD strains appear to bridge the genetic gap between hemp and drug-types, and federally grown research grade marijuana was genetically more similar to hemp than Cannabis available through the legal cannabis market. Genetic imposters within a strain had measurable aromatic differences, but there was considerable variation in aromas among samples with identical genetic identity. Analyses of both terpene and cannabinoid profiles among individuals with identical genotypes acquired from different sources varied considerably indicating environmental variation has a substantial impact on phenotype in Cannabis. Together these results show a need for the Cannabis industry to implement regulatory checks in the form of genetic testing in order to provide consistency, especially for medical applications. These results demonstrate the need for genotyping in order for phenotypic consistency to be achieved if standard growing conditions can be established. When genetic verification and standard protocols are established, deviations in phenotypic changes can be identified and disclosed to consumers so they are aware that there may be abnormal effects. This investigation highlights the need for additional research to provide consistent products, which is especially important for medical marijuana flower products. In order to provide consumers consistent products, it is imperative to understand sources of variation. Consumers deserve to be provided with quality consistent products as the industry continues to grow on a global scale.

Examining The Roles Of The Receptor Tyrosine Kinase Pvr And The Bone Morphogenic Protein Receptor Thickvein In Regulating Self-Renewal And Division Frequency In The Cyst Stem Cells Of The Drosophila Testis Niche, Nastaran Soleimanibarzi Mues

Dissertations

Adult stem cells live in different tissues, and they support and regenerate both the tissue they reside in and themselves. The stemness behavior is tightly regulated by the niche. The Drosophila testis is a valuable model to study stem cells in their niche. In this niche, there are two populations of stem cells; germline stem cells (GSCs) and somatic cyst stem cells (CySCs). GSCs and CySCs provide the cellular structure required to maintain the production of sperm in Drosophila males. These stem cells co-mingle around a group of non-dividing somatic cells known as the hub, and is the niche that …

In Thailand, it was found that challenging behaviors of students with disabilities had an effect on teachers’ stress because many teachers perceived that they were lacking the knowledge and skills to deal with these problems. The primary purpose of this study was to evaluate the effectiveness of a modified version of a basic functional assessment (FBA) training package developed by Loman and Horner (2014) on increasing the knowledge and skills of Thai special education teachers with respect …

Supervision Of Sex Counseling In Counselor Education: A Phenomenological Study From A Sex Positive And Multiculturally Sensitive Perspective, Reka K. Farago

Dissertations

While existing literature indicates the importance of supervision in counselor training (Bernard & Goodyear; 2003; Harris & Hayes, 2008; Lofrisco, 2013) and counseling efficacy with sexual topics (Bidell, 2005; Harris & Hayes, 2008), counselor educators’ role with supervising client sexual issues is unknown. Currently, 50% of American Counseling Association (ACA) members report uncertainty in how to address sexual concerns with clients (Blount, Booth, Webb, & Liles, 2017). As supervision is paramount in counselor training (Bernard & Goodyear, 2003) and Counselors in Training (CITs) increasingly inquire about working with sexual topics, a study in supervisor experiences with sexual topics is timely. …

You Look Like Me: The Impact Of Demographic Similarity On Picture Primes’ Effectiveness, Jennifer L. Unnerstall

Dissertations

Past research has clearly demonstrated the ability of various primes to influence behavior; however, little is understood about how and why primes work. The present research takes a theory-based approach to begin to understand this further. First, it investigates whether a picture prime has the ability to influence cooperative and competitive concept activation and implicit associations. Then, it examines whether the characteristics of the picture prime, specifically the race of the individuals depicted in the prime and whether it matches the race of the participant (i.e., demographic similarity), moderate these effects. Secondly, the present research investigates whether the same picture …

The Perception Of Physical Activity And Social Support For Physical Activity Among Native Hawaiians 55 Years And Older, Verna Hanashiro

Peroxisomal Protein Defects Disrupt Coordinated Peroxisomal Processes And Affect Early Seedling Development Through Accumulating Toxic Catabolic Intermediates, Ying Li

Dissertations

Many peroxisomal proteins act in β-oxidation processes on a range of substrates. It is unclear how these proteins are coordinated to determine the flux of peroxisomal processes and meet the requirements for plant growth and development. Using mutant analysis and metabolic profiling, I examined proteins predicted to act in fatty acid and indole-butyric-acid (IBA) β-oxidation. ECH2 confers enoyl-CoA hydratase activity for the auxiliary β-oxidation of fatty acids with an even cis-unsaturated bond. ECH2 was suggested to function in IBA β-oxidation, as ech2 seedlings have altered IBA response. ech2 seedlings have reduced root length and cotyledon area. ech2 seedlings accumulate 3-hydroxyoctenoate …

Understanding Comorbid Depression In The Context Of Ptsd Through Underlying Dimensions, Melissa Turkel

Dissertations

Depression co-occurs with Posttraumatic Stress Disorder at a high rate, resulting in numerous complications for pathology and treatment. More research is needed regarding variables that may explain this common comorbidity. One possible variable is that of underlying dimensions, latent factors that give rise to these manifestations of psychopathology. This study explored potential underlying mechanisms of comorbid PTSD and depression, including negative affect, rumination, emotion dysregulation, neuroticism, and behavioral inhibition. While previous studies have investigated these dimensions individually, there is a dearth of research that simultaneously investigates multiple dimensions or determines the relative contributions of underlying dimensions to psychopathology. Thus, the …

Application Of The Picoloyl Group In Carbohydrate Chemistry, Michael Mannino

Dissertations

Stereocontrol of glycosylation reactions is a constant struggle in the field of synthetic carbohydrate chemistry. The application of the picoloyl (Pico) substituent can offer numerous stereocontrolling avenues. The most popular application is the Hydrogen-bond-mediated Aglycone Delivery (HAD) method that provides excellent selectivity in the glycosylation of a variety of sugar substrates. The HAD method relies on the formation of an intermolecular hydrogen bond between the nitrogen atom of the Pico substituent on the glycosyl donor with the hydroxyl group of the glycosyl acceptor. This interaction provides a facial preference for the nucleophilic attack and hence provides powerful stereocontrol for the …

Exploring The Experience Of Benefit Finding In Parents Of Children With Cancer: A Grounded Theory Study, Carol E. Zogran

Dissertations

The diagnosis of cancer in a child is one of the most significant stressors a parent can experience, and research in the area of stress-related effects of illness on parents has emerged in many areas. The majority of studies have focused on the potential or actual negative impact on parents during and after treatment of their child's illness. However, studies that initially set out to explore the difficulties associated with coping with childhood cancer found that parents often reported positive aspects about the experience.

The Rebel Made Me Do It: Mascots, Race, And The Lost Cause, Patrick Smith

Dissertations

Public memory is commonly tied to street names, toponyms, and monuments because they are interacted with daily and are often directly associated with race, class, and regimes of power. Mascots are not thought of in the same manner although they are present as part of everyday life. The childish or sometimes comedic nature of the mascot discounts it from many considerations of its influence, symbolism and history. Nonetheless this research focuses on the term “Rebel” as a secondary school mascot. The term possesses the trappings of race because the American vernacular ties the word to the Confederate States of America …

The Social-Construct Of Race And Ethnicity: One’S Self-Identity After A Dna Test, Kathryn Ann Wilson

Dissertations

Self-identity—specific to race and ethnicity—is shaped by a myriad of factors, including genealogical evidence, family lore, learned behaviors and lived experiences. How these various factors affect self-identity varies greatly from individual to individual. Even those raised within the same household may hold different views of who they are. This study examines how individuals’ self-identity is affected by results from DNA testing.

This study is filtered through the lens of Social Constructivism theory and looks at many components which may have impacted how we see ourselves and develop our personal self-identification. The study used mixed methods and sources of data. Quantitative …
