Guest Editorial: Power In Engaged Scholarship: Dimensions And Dynamics Of Knowledge Co-Creation, Margaret Post, Morgan Ruelle Dec 2021

Guest Editorial: Power In Engaged Scholarship: Dimensions And Dynamics Of Knowledge Co-Creation, Margaret Post, Morgan Ruelle

Sustainability and Social Justice

Collaboratively engaged research is shaped by dynamic power relationships among individuals, institutions and communities. Where some disciplines have explored the theoretical and methodological implications of power relations, the engagement movement writ large has suffered from a lack of explicit conceptual models and in-depth analyses of the role of power in the process of knowledge co-creation. Over the last 30 years, considerable attention has been paid to how resources and expertise within academic institutions can be brought to bear on the intractable social and economic problems of local communities. A necessary, yet under-theorised aspect of these dynamics is the extent to …

Kentucky Teacher Education Journal: The Journal of the Teacher Education Division of the Kentucky Council for Exceptional Children

Whether instruction is happening in traditional classroom settings or through a variety of virtual platforms, successful teaching requires that all teachers possess the ability to collaborate with others, evaluate student performance, establish quality learning environments, and individualize instruction. Drawing on the 2017 Council for Exceptional Children (CEC) publication, High-Leverage Practices for K-12 Special Education Teachers (McLeskey et al., 2017), the Special Education faculty at Eastern Kentucky University describe ways in which four intertwined components of collaboration, assessment, social/ emotional/behavioral practices, and instruction are incorporated into teacher preparation courses to equip candidates with skills to meet the individualized learning needs of …


The Why, The Who, The How… A Guide To Planning Effective, Collaborative, Person-Centered Transition Services For Students With Disabilities, Kristie Covington, Lorita Rowlett Dec 2021

The Why, The Who, The How… A Guide To Planning Effective, Collaborative, Person-Centered Transition Services For Students With Disabilities, Kristie Covington, Lorita Rowlett

Kentucky Teacher Education Journal: The Journal of the Teacher Education Division of the Kentucky Council for Exceptional Children

Providing effective transition services and plans for students with disabilities can seem like a daunting task to special education teachers and supporting agencies. Planning effective collaboration and coordination between stakeholders increases the likelihood that students with disabilities will graduate high school and participate in desired postsecondary activities, be it paid employment or postsecondary education (NTACT, 2019). Many special education teachers and supporting agencies are unsure where to start when planning and coordinating transition services; in response we created a document that can be used as a guidance and planning tool to design effective, person-centered, collaborative transition services. The planning tool …

Large-scale water transfer projects (LWTPs) transfer water to urban and agricultural areas. The Majes-Siguas canal, established in 1983, is an LWTP that created a thriving agricultural area through irrigating the Majes district in the Atacama Desert of Peru. Like other LWTP receiving basins, the project has attracted an influx of migrants who work on the farms. At the same time, the Majes LWTP is the district’s only source of water and has an aging infrastructure which presents significant risks. While many studies critically analyze the consequences of LWTPs in water supply basins, few evaluate the resilience of communities living in …

Approval Among Democrats Fuels Uptick In Biden Approval In Granite State 12/21/2021, Unh Survey Center Dec 2021

Approval Among Democrats Fuels Uptick In Biden Approval In Granite State 12/21/2021, Unh Survey Center

All UNH Survey Center Polls

President Joe Biden's approval rating has improved slightly, with state residents now evenly divided in their assessment of his job performance. Biden's approval among Democrats, which had declined for months, now matches marks from earlier in his presidency. Slim majorities disapprove of Biden's handling of foreign affairs and the economy, but a small majority approve of his handling of COVID-19. Only a quarter of Granite Staters feel the country is headed in the right direction.


Perinatal Corticosteroids: Latent Neurodevelopment Of The Preterm Infant, Isabell Biene Purdy Dec 2021

Perinatal Corticosteroids: Latent Neurodevelopment Of The Preterm Infant, Isabell Biene Purdy

Dissertations

The purpose of this study was to evaluate potential relationships between perinatal dexamethasone treatment of premature infants and latent child development. Often, postnatal corticosteroid (PNS) is offered in the neonatal intensive care unit (NICU) to wean mechanical ventilation. Experts suggested minimizing PNS use after studies identified higher milligrams per kilogram (mg/kg) as a risk factor for adverse developmental outcomes. This study quantified fetal dexamethasone and cumulative perinatal dexamethasone by mg/kg exposure to accurately assess associations between steroid exposure and premature infant behavioral development.


Informing Effective Simulation Pedagogy In Nursing Simulation, Sherry L. Barnard Dec 2021

Informing Effective Simulation Pedagogy In Nursing Simulation, Sherry L. Barnard

Dissertations

Simulation methods are now widely used in nursing education programs. Several studies have been conducted that examine the effect of simulation on student outcomes in learning (Alinier, Hunt, Gordon, & Harwood, 2006; Arnold, et al, 2009; Rosen, Salas, Silvestri, Wu, & Lazzara, 2008), however, little has been discovered regarding models of faculty support and guidance during simulation. The factors that influence student learning in the simulation experience suggest faculty be a guide by offering cueing and support before, during, and after the simulation process (Parsh, Roberts, & Green, 2010). It is also suggested that debriefing be non-judgmental and a time …


A Nationally Representative Survey Of Depression Symptoms Among Jordanian Adolescents: Associations With Depression Stigma, Depression Etiological Beliefs, And Likelihood To Seek Help For Depression, Latefa Ali Dardas Dec 2021

A Nationally Representative Survey Of Depression Symptoms Among Jordanian Adolescents: Associations With Depression Stigma, Depression Etiological Beliefs, And Likelihood To Seek Help For Depression, Latefa Ali Dardas

Dissertations

Arab adolescents are considered a particularly vulnerable population to depression. The substantial lack of mental health services and the stigma associated with mental illness on the one hand; and poverty, unemployment, and lack of reasonable hopes for a decent future in the context of corruption of regimes and perceived social injustice on the other, call for establishing committed and effective policies to tackle depression and its associated stigma among Arab adolescents at risk for or diagnosed with depression. However, there is a substantial lack of research that can inform the current profile of adolescent depression in the Arab region. We …

The Health-Related Quality Of Life Of Adults With Down Syndrome, Rebecca Jermyn Graves

Dissertations

The purpose of this study was to examine the health-related quality of life (HRQOL) and factors associated with the HRQOL of adults with Down syndrome (DS) as reported by adults with DS and their caregivers. The study was designed to compare measures of HRQOL, health problems, health risks, and health-care utilization of adults with DS based on self-report with those from caregiver-report and to explore associations between HRQOL and health problems, health risks, health-care utilization, adaptive behavior, and demographic characteristics.


Police Use Of Social Media Technologies, Akpomudiare Darlynton Adegor Dec 2021

Police Use Of Social Media Technologies, Akpomudiare Darlynton Adegor

Theses and Dissertations

This study used a qualitative research design to analyze how the Little Rock Police Department (LRPD) utilizes social media technologies to promote its community policing philosophy. I conducted a content analysis on 586 tweets by LRPD and 992 public responses posted between May 2020 and May 2021. From my analysis, I found that LRPD social media platforms support both community policing and problem-solving. LRPD uses social media for interactions, connections, and partnerships with community members. The second notable finding was that the public is responsive and receptive to LRPD’s use of social media to connect with them. However, LRPD’s level …


Simulated Presence Use For Quality Of Life Maintenance And Reduction Of Symptoms Of Distress In Persons Living With Dementia In Long-Term Care, Erin E. Bush Dec 2021

Simulated Presence Use For Quality Of Life Maintenance And Reduction Of Symptoms Of Distress In Persons Living With Dementia In Long-Term Care, Erin E. Bush

Dissertations

Nursing home residents with dementia often have an array of neuropsychiatric symptoms, including dementia-related agitation. It is theorized that many of these agitation symptoms occur due to unmet psychosocial needs that could be met by the presence of a caring nursing staff member, family member, or friend.

The purpose of this study was to determine whether live simulated presence improves dementia-related agitation when offered, identify barriers and facilitators to simulated presence between caregivers and residents of long-term care during the COVID-19 pandemic, and to determine if live simulated presence by a caregiver delivered one-on-one improved quality of life in long-term …


Kinematics And Kinetics Of Capacitated And Non-Capacitated Mouse Sperm, Alicia Gupte Dec 2021

Kinematics And Kinetics Of Capacitated And Non-Capacitated Mouse Sperm, Alicia Gupte

Mechanical Engineering and Materials Science Independent Study

The differences in kinetic measurements of force, work, power, and torque are quantitativly observed between non-capacitated and capacitated sperm. Isomap, a nonlinear dimensionality reduction technique, is used to get higher resolution imaging data of the sperm videos. This allowed accurate calculations of spatial and temporal derivatives to calculate the kinetics of the flagella. The results showed no statistical significance between the kinetic measurements of non- capacitated and capacitated mouse sperm.

Participants with symptom onset within 8 days were enrolled, then transfused within the subsequent day. The measured primary outcome was COVID-19-related hospitalization within 28 days of plasma transfusion. The enrollment period was June 3, 2020 to …


A Hybrid Machine Learning Framework For Predicting Students’ Performance In Virtual Learning Environment, Edmund Evangelista Dec 2021

A Hybrid Machine Learning Framework For Predicting Students’ Performance In Virtual Learning Environment, Edmund Evangelista

All Works

Virtual Learning Environments (VLE), such as Moodle and Blackboard, store vast data to help identify students' performance and engagement. As a result, researchers have been focusing their efforts on assisting educational institutions in providing machine learning models to predict at-risk students and improve their performance. However, it requires an efficient approach to construct a model that can ultimately provide accurate predictions. Consequently, this study proposes a hybrid machine learning framework to predict students' performance using eight classification algorithms and three ensemble methods (Bagging, Boosting, Voting) to determine the best-performing predictive model. In addition, this study used filter-based and wrapper-based feature …

Background Tricuspid regurgitation (TR) is a common finding in adults with congenital heart disease referred for pulmonary valve replacement (PVR). However, indications for combined valve surgery remain controversial. This study aimed to evaluate early results of concomitant tricuspid valve intervention (TVI) at the time of PVR. Methods and Results Observational studies comparing TVI+PVR and isolated PVR were identified by a systematic search of published research. Random-effects meta-analysis was performed, comparing outcomes between the 2 groups. Six studies involving 749 patients (TVI+PVR, 278 patients; PVR, 471 patients) met the eligibility criteria. In the pooled analysis, both TVI+PVR and PVR reduced TR …

Myeloid-derived suppressor cells (MDSCs) represent an innate immune cell population comprised of immature myeloid cells and myeloid progenitors with very potent immunosuppressive potential. MDSCs are reported to be abundant in the lungs of active tuberculosis (TB) patients. We sought to perform an in-depth study of MDSCs during latent TB infection (LTBI) and active TB (ATB) using the nonhuman primate (NHP) model of pulmonary TB. We found a higher proportion of granulocytic, polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) in the lungs of ATB animals compared to those with LTBI or naive control animals. Active disease in the lung, but not LTBI, was …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a historic pandemic of respiratory disease (coronavirus disease 2019 [COVID-19]), and current evidence suggests that severe disease is associated with dysregulated immunity within the respiratory tract. However, the innate immune mechanisms that mediate protection during COVID-19 are not well defined. Here, we characterize a mouse model of SARS-CoV-2 infection and find that early CCR2 signaling restricts the viral burden in the lung. We find that a recently developed mouse-adapted SARS-CoV-2 (MA-SARS-CoV-2) strain as well as the emerging B.1.351 variant trigger an inflammatory response in the lung characterized by the expression of …
