Genetically Modified Corn Diffusion And Biofuel Usage: Impacts On Corn Belt Cropping Systems Changes, Kenneth Annan

Electronic Theses and Dissertations

The adoption of genetically modified (GM) crops, the rise of ethanol production that produced an additional derived demand for corn, and the increasingly prominent position of corn and soybeans in crop rotations embody major changes in U.S. agriculture during the past decades. This study investigates the linkages among these developments in two ways. First, we look at how biotechnology and biofuels have influenced cropping system changes in the Corn Belt region of the United States, using state-level data from 2000 to 2019. Second, we investigate the determinants of corn acreage intensification levels and heterogeneity at the state level using data …

Extended Pseudo Invariant Calibration Site-Based Trend-To-Trend Cross-Calibration Of Optical Satellite Sensors, Prathana Khakurel

Electronic Theses and Dissertations

Satellite sensors have been extremely useful and are in massive demand in the understanding of the Earth’s surface and monitoring of changes. For quantitative analysis and acquiring consistent measurements, absolute radiometric calibration is necessary. The most common vicarious approach of radiometric calibration is cross-calibration, which helps to tie all the sensors to a common radiometric scale for consistent measurement. One of the traditional methods of cross-calibration is performed using temporally and spectrally stable pseudo-invariant calibration sites (PICS). This technique is limited by adequate cloud-free acquisitions for cross-calibration which would require a longer time to study the differences in sensor measurements. …

Classification And Evaluation Of Extended Pics (Epics) On A Global Scale For Calibration And Stability Monitoring Of Optical Satellite Sensors, Juliana Maria Fajardo Rueda

Electronic Theses and Dissertations

As targets for the calibration and monitoring of optical satellite sensors, historically stable areas across North Africa have been used, known as Pseudo Invariant Calibration Sites PICS. However, two major drawbacks exist for these sites; first is the dependency on a single location to be always invariant, and second is the limited amount of observation achieved using these sites. As a result, longer time periods are needed to construct a dense data set to assess the radiometric performance of on-orbit optical sensors, and be convinced that the change detected is sensor-specific rather than site-specific. This work presents a global land …

Detection Of Change Points In Pseudo-Invariant Calibration Sites Time Series Using Multi-Sensor Satellite Imagery, Neha Khadka

Electronic Theses and Dissertations

The remote sensing community has extensively used Pseudo-Invariant Calibration Sites (PICS) to monitor the long-term in-flight radiometric calibration of Earth-observing satellites. The use of the PICS has an underlying assumption that these sites are invariant over time. However, the site’s temporal stability has not been assured in the past. This work evaluates the temporal stability of PICS by not only detecting the trend but also locating significant shifts (change points) lying behind the time series. A single time series was formed using the virtual constellation approach in which multiple sensors data were combined for each site to achieve denser temporal …

Encroachment: College Athletes’ Experiences With Identity Development As Affected By Media Representations Of Social Justice Demonstrations, Madison Remi Vanwalleghen

Electronic Theses and Dissertations

This study was conducted to understand how communication and identity are experienced by Black university athletes in asking about their experiences and how they gauge mainstream media portrayals of Black NFL athletes making verbal or physical statements about or in protest of social injustice, racism, and inequality in America. I interviewed five university athletes identifying as Black/African American or Mixed- Race using media representations of Black NFL athletes’ protests since the NFL has dominated mainstream media headlines regarding recent athletes’ protests, especially in connection to the Black Lives Matter social movement. I also used several theories to interpret the data …

Policy And Economic Variables Influencing Adoption Of Sustainable Electrification In Rural Sub-Saharan Africa, Payne William Morgan

Graduate College Dissertations and Theses

Limited access to electricity remains a primary constraint to economic growth and the improvement of livelihoods throughout sub-Saharan Africa. In rural areas, electricity access is especially sparse. The reasons for the scarcity of electricity supply in the region are well documented, with low population density, limited household incomes, and poor regulatory institutions compounding to often make the investment of expanding electricity access result in poor or risky economic returns. However, the declining cost of solar PV and mandates for clean energy development throughout the region have created new channels for bringing electricity supply in potentially more cost-effective ways.Despite these macro …

With the advent of the COVID-19 pandemic, online environments have become critical ways of connecting among college students. With the increase in online interactions, cybervictimization has been identified as a public health issue. This study aims to examine whether cybervictimization among college students is associated with clinical adjustment outcomes such as depression and alcohol consumption. This study also aims to examine whether reactivity in the two branches of the autonomic nervous system (sympathetic and parasympathetic) jointly moderate the relationship between cyberbullying and depression/alcohol consumption, indicating sensitivity to the environment. Participants (n =164, 69% female, M age = 19.92, SD = …

Exploring The Determinants Of Aspects Of Rotational Grazing In The U.S. Great Plains, Iftekhar Uddin Ahmed Chowdhury

Electronic Theses and Dissertations

Pasture and rangeland make up about 45 percent of the agricultural land in the U.S. Great Plains and one of the most common form of mismanagement of this pasture is overgrazing. Which results in many detrimental effects on environment. Many practitioners endorsed Rotational grazing (RG) as an improved grazing management practice over season-long continuous grazing. The overall goal of the current study is to assess the certain aspects of using RG in the U.S. Great Plains. Using mail survey data of the of 874 beef cattle producers of North Dakota, South Dakota, and Texas, the study found that neighborhood practice, …

Are Us Government Foreign Aid Flows And Fdi Flows Intertemporally Related? An Investigation Of Twenty-Three Countries In Sub-Saharan Africa, Ravi Kumar Datt Panchagnula

Electronic Theses and Dissertations

In this thesis, I test my central hypothesis that United States government foreign aid flows and FDI flows from anywhere in the world to Sub-Saharan Africa are intertemporally related; thus, I test to what extent FDI flows follow—and, thus, are caused by—aid flows or to what extent aid flows follow—and, thus, are caused by—FDI flows. My panel dataset includes twenty-three Sub-Saharan countries and spans 1991 to 2018. Based on the results of pooled-OLS and panel fixed-effects regressions, and panel Granger causality tests, I show that aid and FDI are intertemporally related. Additionally, Granger-causality is bidirectional: FDI Granger-causes United States government …

Using New And Long-Term Multi-Scale Remotely Sensed Data To Detect Recurrent Fires And Quantify Their Relationship To Land Cover/Use In Indonesian Peatlands, Yenni Vetrita

Electronic Theses and Dissertations

Indonesia has committed to reducing its greenhouse gases emissions by 29% (potentially up to 41% with international assistance) by 2030. Achieving those targets requires many efforts but, in particular, controlling the fire problem in Indonesia’s peatlands is paramount, since it is unlikely to diminish on its own in the coming decades. This study was conducted in Sumatra and Kalimantan peatlands in Indonesia. Four MODIS-derived products (MCD45A1 collection 5.1, MCD64A1 (collection 5.1 and 6), FireCCI51) were initially assessed to explore long-term fire frequency and land use/cover change relationships. The results indicated the product(s) could only detect half of the fires accurately. …

Broccoli Over Brownies: Factors Affecting Healthy Food Choices For Low Income Residents Of Sioux Falls, South Dakota, Aileen Patricia Profir

Electronic Theses and Dissertations

The world is on the cusp of a nutritional crisis: malnutrition, in all its forms, now directly affects one in three persons on the planet. Chronic malnutrition is closely associated with a wide range of public health issues such as stunted growth, increased incidence of disease, school or work absences, and obesity. Access to proper nourishment for food insecure individuals is often evaluated as a measure of distance to market, yet a causal relationship between proximity to food resources and improved health outcomes is unclear. Multiple dimensions of food access influence fruit and vegetable consumption for those who are food …

Go Talk To Your Employee: A Sequential Mediation Analysis Of Leader Communication Frequency And Employee Turnover Intent, Max Weaver

Electronic Theses and Dissertations

Employee turnover has significant negative costs to healthcare organizations. While leadership communication styles and quality have been empirically supported to reduce turnover intentions, our understanding of specific modalities of leader intervention is not well understood. This paper sought to understand how the specific act of communication frequency reduces turnover. Through the lens of Leader-Member Exchange (LMX) and role dynamic theories, mediating effects of LMX quality and job satisfaction were investigated to further understand this proposed relationship in a sample of healthcare workers in the Midwest/US. Results indicate that communication frequency was negatively related to turnover intent. Furthermore, while LMX and …

Depression Symptoms Of College Students During Covid-10 And The Universities’ Response, Anamika Paulay

WWU Honors College Senior Projects

In early spring 2020, universities worldwide shut down their campuses in response to a global pandemic. The present study examines the potential effect of the shutdown and other pandemic-related stresses on student well-being at Western Washington University. It assesses students’ depression symptoms using the IDAS-II General Depression Scale. The study also considers two campus resources (the Counseling Center, and Prevention and Wellness Services) that students can turn to for help with mental health issues, and gauges students’ awareness and utilization of these resources. The study subjects were Western undergraduates (N = 252), who answered a survey that included the IDAS-II …

Debugging By Design: A Constructionist Approach To High School Students’ Crafting And Coding Of Electronic Textiles As Failure Artifacts, Deborah A. Fields, Yasmin B. Kafai, Luis Morales-Navarro, Justice T. Walker

Instructional Technology and Learning Sciences Faculty Publications

Much attention in constructionism has focused on designing tools and activities that support learners in designing fully finished and functional applications and artifacts to be shared with others. But helping students learn to debug their applications often takes on a surprisingly more instructionist stance by giving them checklists, teaching them strategies or providing them with test programs. The idea of designing bugs for learning—or debugging by design—makes learners agents of their own learning and, more importantly, of making and solving mistakes. In this paper, we report on our implementation of “Debugging by Design” activities in a high school classroom over …

Is Perfectionism Always Unhealthy? Examining The Moderating Effects Of Psychological Flexibility And Self-Compassion, Clarissa W. Ong, Eric B. Lee, Julie M. Petersen, Michael E. Levin, Michael P. Twohig

Psychology Student Research

Objectives: Perfectionism is generally associated with worse mental health outcomes, though evidence suggests elements of it might be helpful. In light of these findings, we examined whether psychological skills like psychological flexibility and self-compassion moderated the relationship between perfectionism and wellbeing (i.e., quality of life, symptom impairment, and psychological distress).

Methods: Undergraduate students (N= 677) completed self-report measures.

Results: A latent profile analysis identified three perfectionism groups (low, average, high) based on four perfectionism subscales: concern over mistakes, need for approval, rumination, and striving for excellence. Generally, we found that psychological flexibility and/or self-compassion buffered the impact of average and …

Neural Efficiency And Spatial Task Difficulty: A Road Forward To Mapping Students' Neural Engagement In Spatial Cognition, Ariel W. Snowden, Christopher M. Warren, Wade H. Goodridge, Ning Fang

Psychology Student Research

The current study examined the neural correlates of spatial rotation in eight engineering undergraduates. Mastering engineering graphics requires students to mentally visualize in 3D and mentally rotate parts when developing 2D drawings. Students’ spatial rotation skills play a significant role in learning and mastering engineering graphics. Traditionally, the assessment of students’ spatial skills involves no measurements of neural activity during student performance of spatial rotation tasks. We used electroencephalography (EEG) to record neural activity while students performed the Revised Purdue Spatial Visualization Test: Visualization of Rotations (Revised PSVT:R). The two main objectives were to 1) determine whether high versus low …

Does The Cognitive Fusion Questionnaire Measure More Than Frequency Of Negative Thoughts?, Jennifer Krafft, Michael E. Levin

Psychology Student Research

Cognitive fusion is a psychopathological process that appears to be relevant to a wide range of disorders. This process is frequently measured with the Cognitive Fusion Questionnaire (CFQ). However, the construct validity of similar measures has been criticized for substantial overlap with distress. It is possible the CFQ may excessively measure the presence of unwanted thoughts, rather than fusion per se. Therefore, this study examined the discriminant validity of the CFQ relative to a measure of automatic negative thoughts (the Automatic Thoughts Questionnaire) in a college student sample (n = 389). While the two measures were highly correlated (ρ …

Confirmatory Factor Analysis And Measurement Invariance Of The Cognitive Fusion Questionnaire-Body Image In A Clinical Eating Disorder Sample, Jennifer L. Barney, Tyson S. Barrett, Tera Lensegrav-Benson, Benita Quakenbush, Michael P. Twohig

Psychology Student Research

Individuals with eating disorders (EDs) may be particularly susceptible to body image related cognitive fusion(i.e., excessive entanglement with one’s body image related thoughts such that they unduly influence on behavior). The Cognitive Fusion Questionnaire-Body Image (CFQ-BI) is the only existing measure of this construct, yet its psychometric properties have not been examined within a clinically diagnosed ED sample. The current study used confirmatory factor analysis and explored measurement invariance, construct validity, and incremental validity of the CFQ-BI when used with adolescent (n = 75) and adult (n= 100) females admitting to residential ED treatment. A modified version of the single-factor …

Preliminary Findings On Processes Of Change And Moderators For Cognitive Defusion And Restructuring Delivered Through Mobile Apps, Michael E. Levin, Jennifer Krafft, Woolee An, Clarissa W. Ong, Michael P. Twohig

Psychology Student Research

A process-based therapy approach emphasizes examining how and for whom specific therapeutic components linked to specific processes of change function. This preliminary study explored the processes of change for cognitive defusion and restructuring with daily ratings of self-criticism from a larger component trial as well as self-compassion as a moderator of these daily effects. A sample of 51 adults high in self-criticism (M age = 22.69, 78% female, 88% non-Hispanic White) were randomized to a cognitive defusion or restructuring mobile app for two weeks and completed daily assessments. Both conditions improved over time on daily frequency, defused noticing, challenging, …

Integrating Storytelling Into The Theory And Practice Of Contextual Behavioral Science, Carter H. Davis, Brandon A. Gaudiano, Louise Mchugh, Michael E. Levin

Psychology Student Research

The practice of generating and interpreting stories can be examined through a behavioral lens and has many potential implications for clinical practice. However, storytelling has for the most part yet to be integrated into the field of contextual behavioral science (CBS). A bedrock of human culture, storytelling has influenced both individual behavior and intergroup cooperation for millennia. Basic principles of relational frame theory, such as those pertaining to coherence, perspective-taking, and the transformation of stimulus function, may help to reveal how stories derive their psychological impact. In turn, understanding storytelling from a CBS perspective can facilitate the broader integration of …

Examining The Feasibility And Effectiveness Of Online Acceptance And Commitment Therapy Self-Help In A Quasi-Stepped Care Model: A Pilot Study, Clarissa W. Ong, Carina L. Terry, Michael Levin, Michael P. Twohig

Psychology Student Research

The global burden of mental illness and limited resources make increasing the efficiency of available mental healthcare resources especially crucial. One way this can be done is a stepped care approach to treatment. To test the viability of using internet-based self-help in a stepped care model, we examined the feasibility, acceptability, and effectiveness of an online self-help acceptance and commitment (ACT) program prior to starting in-person therapy at a university community clinic (N = 51). Online program acceptability was at least moderate. There was clinically significant change in 75.9 to 79.3% and reliable change in 31.0 to 100% of …

Weight-Related Psychological Inflexibility As A Mediator Between Weight Self-Stigma And Health-Related Outcomes, Julie M. Petersen, Carrie Durward, Michael Levin

Psychology Student Research

Weight self-stigma, the internalization of negative societal stereotypes, is a problem amongst populations with high weight. Weight self-stigma is associated with psychological inflexibility and maladaptive health-related behaviors. In this study, we explore how weight-related psychological inflexibility may influence weight self-stigma and health-related outcomes in 79 adults with high weight. Participants were primarily white (92.4%) and female (82.3%), with an average age of 39.56 and average body mass index of 33.78. The present study uses baseline, self-report data from a larger trial. Results indicate that weight self-stigma was negatively correlated with maladaptive eating behaviors, weight, and mental health. Weight-related psychological inflexibility …

A Systematic Review And Psychometric Evaluation Of Self-Report Measures For Hoarding Disorder, Clarissa W. Ong, Jennifer Krafft, Michael E. Levin, Michael P. Twohig

Psychology Student Research

Background: Hoarding disorder (HD) affects approximately 2.5% of the general population, leads to significant distress and impairment, and is notoriously difficult to treat. The crux of developing effective treatments for HD is our ability to reliably and validly measure relevant constructs in HD to better understand its presentation and, subsequently, formulate appropriate interventions.

Methods: We identified measures specific to HD and evaluated their psychometric properties using rating criteria formulated by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) group.

Results: The 17 included measures were developed to assess adult and pediatric hoarding severity, functional impairment, and maladaptive …

An Open Trial Of Group Acceptance And Commitment Therapy (Act) With An Adjunctive Mobile App For Generalized Anxiety Disorder (Gad), Jennifer Krafft, Clarissa W. Ong, Carter H. Davis, Julie M. Petersen, Michael E. Levin, Michael P. Twohig

Psychology Student Research

Generalized anxiety disorder (GAD) is a common and debilitating condition. Effective treatments exist, but they are time-and resource-intensive. This study tested the initial efficacy and acceptability of a novel treatment protocol designed to increase efficiency: acceptance and commitment therapy (ACT) taught in groups and through an adjunctive mobile app. Participants were 21 individuals with GAD who received six weeks of 2-hour group ACT sessions as well as access to an adjunctive ACT mobile app. Significant improvements occurred in worry, anxiety, social functioning, and depression as well as relevant processes (psychological inflexibility, anxiety-related cognitive fusion). In-the-moment improvements were also observed in …

The Role Of Psychological Inflexibility And Perspective Taking In Anti-Racism And Anti-Sexism, Carter Davis, Jennifer Krafft, Elizabeth Tish Hicks, Michael E. Levin

Psychology Student Research

Racism and sexism are pervasive forms of discrimination that cause significant individual and societal burden.Understanding manipulable psychological processes that contribute to these modes of discrimination would aid in developing anti-prejudice interventions that target them. Psychological flexibility has been proposed as a potential tool in combating prejudice by modifying one’s relationship with unwanted or automatic prejudicial thoughts, in addition to the ability to take the perspective of marginalized groups. A survey assessing psychological inflexibility and perspective taking along with anti-racist/anti-sexist attitudes and behaviors was administered to a sample of 395 undergraduate students. Perspective taking predicted anti-racist/anti-sexist behaviors above and beyond their …

Human Development and Family Studies Faculty Publications

The Mental Health Awareness and Advocacy Assessment Tool l (MHAA-AT) consists of three types of items: 1) declarative knowledge items (30 items); 2) self-efficacy items (20 items); and 3) behavior items (15 items). These items are then divided into the three micro-processes that define mental health literacy: a) identifying mental health issues; b) locating evidence-based resources; and c) responding to mental health issues (see Figure 1 below).

Parental Influences On Children’S Decisions Making, Karinna Anne Rodriguez

UNF Graduate Theses and Dissertations

There is currently not enough research that focuses on parental influences on children’s development of decision making in early childhood. During early childhood children are primarily situated in the family context and are likely learning about decision making through their interactions with parents. Previous research has suggested children begin to develop complex decisions-making skills in early childhood. Complex decision-making includes the ability to consider the future and social benefits for the self and others. Future-oriented decisions requires the difficult task of deliberating between sacrificing an instant reward for a larger reward in the future, while social-oriented decisions require the consideration …

Disentangling The Role Of Self-Esteem On Eating Disorders In African American Youth, Carly Alexandria Wagner

UNF Graduate Theses and Dissertations

Self- esteem (SE) has been identified to have a significant impact on eating disorders (ED). Although previous studies have found a relationship between SE and EDs, further investigation in needed because SE and EDs affect gender, age, weight status, and ethnicity heterogeneously. In particular, there is limited research and inconsistent findings on the impact of SE on EDs in youth, males, and African Americans (AAs). This study had six aims: 1) Observe gender and age differences in SE, 2) Examine the impact of weight status on SE, 3) Observe gender and age effects on EDs, 4) Examine the impact of …

The Influence Of Autism Spectrum Disorder Disclosure On Peer Social Distancing In Higher Education, Hope Marie Sparks

UNF Graduate Theses and Dissertations

Students diagnosed with Autism Spectrum Disorder are almost twenty percent less likely than their non-autistic peers to graduate college (White et al., 2017). The diagnosis of Autism Spectrum Disorder, or ASD, can be a significant facet of personal identity for many individuals on the spectrum. Due to this, disclosure of diagnoses can be a deeply personal decision and can be situational. Because college-age students on the spectrum are forming an identity concerning their diagnosis (Bent et al, 2016; Cox et al., 2017), peer social distancing behaviors are an important factor in student confidence and academic success. Researchers completed this study …
