Does A Brief Mindfulness Induction Change Delay Discounting In Individuals With High Levels Of Obsessive-Compulsive Symptoms?, Cierra B. Edwards Jan 2021

Does A Brief Mindfulness Induction Change Delay Discounting In Individuals With High Levels Of Obsessive-Compulsive Symptoms?, Cierra B. Edwards

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obsessive-compulsive disorder (OCD) is a mental illness characterized by obsessions and compulsions that cause significant distress and/or functional impairment. Delay discounting, the decline in value of a reward with the delay of its receipt, is linked to a range of maladaptive behaviors and mental disorders. Increased delay discounting is related to obsessive-compulsive disorder (OCD), reflecting that compulsive behaviors that aim to counteract obsessive thoughts are viewed as uncontrollable by the sufferer. We aimed to experimentally reduce delay discounting in individuals with high levels of obsessive-compulsive symptoms through a brief mindfulness induction. Eligible participants were randomly assigned to receive either a …

Covid-19 Vaccine Mandates For University Students, Dorit Rubenstein Reiss, John Dipaolo Jan 2021

Covid-19 Vaccine Mandates For University Students, Dorit Rubenstein Reiss, John Dipaolo

Faculty Scholarship

Universities and colleges (“universities”) reopening after COVID-19 understandably seek to increase safety on campus and reduce the risk of a COVID-19 outbreak. One approach universities and colleges are considering is requiring vaccines from students. This Article addresses the legal framework behind university vaccine mandates for students. It sets out the general constitutional framework and explains why universities are constitutionally permitted to impose reasonable vaccine mandates. It addresses whether universities need to offer a religious exemption, explaining that under current Supreme Court jurisprudence, universities are likely not required to offer a religious exemption, but that may change, and public universities in …

Outpatient Appointment Scheduling Study: Utilization Projection, No-Show Prediction, And Capacity Allocation, Fangzheng Yuan Jan 2021

Outpatient Appointment Scheduling Study: Utilization Projection, No-Show Prediction, And Capacity Allocation, Fangzheng Yuan

Transportation Logistics and Finance

Long waiting times could result in many negative effects, such as low capacity utilization, high patient no-show rates, and loss of social benefits, which will also lead to a waste of public resources. Therefore, to better utilize healthcare resources and serve the community, my dissertation will focus on three objectives: To study the relationship between appointment utilization and indirect waiting time (IWT); to predict the patient’s no-shows without profiling them; to develop an optimization model for appointment capacity allocation. To achieve these objectives, multiple models and approaches have been developed in this dissertation. For the first model, two mixture distribution …

Logistics Of North Dakota State Local Food System: An Empirical Study To Measure Local Food Supply And Demand For Regional Food Hub Feasibility Study, Hamad Alqublan Jan 2021

Logistics Of North Dakota State Local Food System: An Empirical Study To Measure Local Food Supply And Demand For Regional Food Hub Feasibility Study, Hamad Alqublan

Transportation Logistics and Finance

Because North Dakota (ND) is one of only four states that do not have a food hub, the purpose of the regional food hub feasibility study was to empirically evaluate whether the ND local food system needs a food hub from a supply and demand perspective. The 21st century has shifted American agriculture and rural life. The number of small and mid-sized farms decreases while the number of more significant farms increases. The food hubs concept has become an increasingly popular response to this agricultural problem. Food hubs cover the gap between farmers and markets and add value to the …

The Biogeochemistry Of Soil At Depth Within The Wetland Landscape Of The Prairie Pothole Region, Carrie Elaine Werkmeister Jan 2021

The Biogeochemistry Of Soil At Depth Within The Wetland Landscape Of The Prairie Pothole Region, Carrie Elaine Werkmeister

Soil Science

The impact of agricultural practices on wetland ecosystems in the Prairie Pothole Region (PPR) has long been recognized but little is understood about impacts on the biogeochemistry of the wetlands at depth. Understanding the relationship of multi-elements within the wetland and surrounding landscape can aid in wetland restoration and provide guidance for wetland management. The objectives of this study were to: 1) identify biogeochemical characteristics of PPR wetlands; 2) identifying differences or similarities in biogeochemical characteristics of the landscape; 3) assess the vertical variation in chemical composition at depth in wetland, wetland and fringe, footslope and backslope soils; and 4) …

On Lasso Estimation Of Linear Mixed Model For High Dimensional Longitudinal Data, Qian Wen Jan 2021

On Lasso Estimation Of Linear Mixed Model For High Dimensional Longitudinal Data, Qian Wen

Statistics

With the advancement of technology in data collection, repeated measurements with high dimensional covariates have become increasingly common. The classical statistics approach for modeling the data of this kind is via the linear mixed model with temporally correlated error. However, most of the research reported in the literature for variable selection is for independent response data. In this study, the proposed algorithm employs Expectation and Maximization (EM) and Least Absolute Shrinkage and Selection Operator (LASSO) approaches under the linear mixed model scheme with the assumption of Gaussianity, an approach that works for data with interdependence. Our algorithm involves two steps: …

Culturally Responsive School Leadership Agility: A Journey Through Critical Self-Reflection, Deborah Mckelvey Brown Jan 2021

Culturally Responsive School Leadership Agility: A Journey Through Critical Self-Reflection, Deborah Mckelvey Brown

Electronic Theses and Dissertations

This study examined how school leaders can differentiate their approach using a self-reporting psychometric instrument called the Emergenetics® Profile when engaged in critical self-reflection. Using a multiple case study approach, three urban school leaders engaged in the deconstructing and reconstructing of knowledge frameworks specific to deficit thinking. The Emergenetics Profile served as a lens to critically self-reflect in order to differentiate their approach to the disrupt deficit thinking practices in their schools (Browning 2007; Khalifa, 2018; Shields, 2018). This study integrated these insights from critical self-reflection and the awareness gained by school leaders through their Emergenetics preferences to change their …

“It Sucks, But I’M Grateful”: Understanding The Experience Of Autistic Students Living In The Residence Halls, Mary F. Elliott

Electronic Theses and Dissertations

As populations of Autistic students at institutions of higher education increases, it is becoming more important for institutions to evaluate their programs with these students in mind. While the Autistic population has grown, policies and services on campuses have not become more inclusive or supportive of this population as a response. This evaluation examines the Residential Learning Model, the guide through which the residential life program at one institution of higher education is delivered to the students living in the residence halls. Through the lens of the Autistic students and the student staff who live and work in the residence …

Exploring The Impact Of Leadership Values And Practices To Support Equity And Social Justice In An Urban School, Susan-Marie Farmen Jan 2021

Exploring The Impact Of Leadership Values And Practices To Support Equity And Social Justice In An Urban School, Susan-Marie Farmen

Electronic Theses and Dissertations

This qualitative case study explores the leadership values and practices of a principal in a sixth through twelfth-grade school in the Rocky Mountain West to determine how leadership values and practices support the implementation of equitable and socially just practices in the school. Five key themes emerged: (a) equity as a Black/non-Black construct; (b) a lack of knowledge and awareness of the historical contexts of marginalized populations; (c) moral courage for all members of the school; (d) equity as an initiative or program; (e) resistance to deep equity work. From these themes, I devise three recommendations to support substantial and …

Faculty, Staff and Students Publications

Voltage-gated Kv1.3 potassium channels are key regulators of T lymphocyte activation, proliferation and cytokine production, by providing the necessary membrane hyper-polarization for calcium influx following immune stimulation. It is noteworthy that an accumulating body of in vivo and in vitro evidence links these channels to multiple sclerosis pathophysiology. Here we studied the electrophysiological properties and the transcriptional and translational expression of T lymphocyte Kv1.3 channels in multiple sclerosis, by combining patch clamp recordings, reverse transcription polymerase chain reaction and flow cytometry on freshly isolated peripheral blood T lymphocytes from two patient cohorts with multiple sclerosis, as well as from healthy …
