Soil Moisture Prediction Using Meteorological Data, Satellite Imagery, And Machine Learning In The Red River Valley Of The North, Umesh Acharya

Soil Science

Weather stations provide key information related to soil moisture and have been used by farmers to decide various field operations. We first evaluated the discrepancies in soil moisture between a weather stations and nearby field; due to soil texture, crop residue cover, crop type, growth stage and duration of temporal dependency to recent rainfall and evaporation rates using regression analysis. The regression analysis showed strong relationship between soil moisture at the weather station and the nearby field at the late vegetative and early reproductive stages. The correlation thereafter declines at later growth stages for corn and wheat. We can adduce …

Mau Mau’S Moral War: The Sacralization Of Kenya’S Anticolonial Struggle, 1952–1956, Henry Muoki Mbunga

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation is a study of the ethical and religious history of the Mau Mau War in Kenya, 1952–1956. It breaks with a historiographical tradition that reduces Mau Mau’s ritual activities to stage props and backdrops on the historical stage. The project investigates two central questions: (1) why did Mau Mau members invent a variety of rituals during the anticolonial struggle in Kenya? and (2) how did the ethical and religious convictions of Mau Mau members shape their military campaign? Using rare archival sources and the oral histories and published memoirs of Mau Mau War veterans, this study argues that …

In/Visible, Raymond Thompson Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

My MFA thesis and supporting exhibition focus on challenging the United States’ photographic archive that often left out African-American people. The work, through the use of appropriation and alternative photographic processes, disrupts America’s historical visual archive and notions that surround the white gaze. Through the unsettling of this visual space, new speculative narratives can be created to help imagine new futures. This work is the beginning of a process of mourning histories I have never known and reclaiming a place for myself and my family in the American landscape that is free of racial trauma.

#Canceled: Positionality And Authenticity In Country Music’S Cancel Culture, Gabriella Saporito

Graduate Theses, Dissertations, and Problem Reports (ETD)

From its beginning in film and television and its early adoption by Black Twitter, cancel culture has become a phenomenon in the era of social media. Marked by the popular hashtags #cancel, #canceled, #[InsertNameHere]isOverParty, and #Surviving[InsertNameHere], cancel culture is a practice which involves publicly denouncing and/or shaming a person or company when they do something that is considered offensive or objectionable. It saw a resurgence in the era of #MeToo that has not slowed down in an age dominated by social media presidents and global pandemics. Cancel culture has also seen a recent re-adoption by the political right, which begs …

Hr Process Automation: A Bibliometric Analysis, Shubham Mishra, Monica Kunte, Netra Neelam, Sanjay Bhattacharya, Preeti Mulay

Library Philosophy and Practice (e-journal)

Automation is interpreted as the replacement of manual operations by electronics and computer-controlled systems. Human resource management is an indispensable part of every firm be it the space of retail, healthcare, education or any other sector. Activities such as hiring new workers, training, or making sure that local labour laws are obeyed with HR processes and are a crucial part of every organisation. HR has typically been believed of as an extremely manual department procedure. Employees are accustomed to doing this manually and getting the job done themselves. But everything around the HR processes are changing rapidly. HR Automation is …

Strengthening Mental Health Diagnostic Detection In Integrated Primary Care, Julia Brechbiel

Theses and Dissertations

Primary care behavioral health (PCBH) is crucial for providing mental health treatment to underserved, minority, and uninsured populations. There is a lack of knowledge about accurate mental health diagnoses at PCBH. Underdetection of mental health symptoms has the potential to worsen racial and socioeconomic disparities. Using an expert review process, I developed an abbreviated diagnostic clinical interview (ADCI) for integrated primary care. Next, patients (N = 82) completed the interview after attending PCBH appointments. According to the interview, 63.4% of participants met criteria for a diagnosis, while 64.7% received a diagnosis from their provider. A large portion of patients …

Role Of P53 Deficient Clonogenic Endothelial Cells In The Pathogenesis Of Pulmonary Hypertension, Aneel Roy Bhagwani

Theses and Dissertations

Pulmonary Artery Hypertension (PAH) is a progressive disorder of the small vessels of the pulmonary vasculature. It is characterized by occlusive vascular remodeling leading to right heart failure and ultimately death. PAH pathogenesis involves a multifactorial etiology leading to formation of occlusive lesions in small (preacinary) pulmonary arteries. These lesions contain hyper-proliferative, apoptosis resistant endothelial cells (ECs), smooth muscle cells and fibroblasts. ECs play a major role in the development of PAH. These ECs in vascular lesions are primitive and express progenitor cell markers, including CD117 (c-kit).

We have isolated clonally expanded, c-kit+ ECs from the lungs of Green Fluorescent …

Yolkkh: The Story Of My People, Amna Zelimkha Yandarbin

Theses and Dissertations

The name of my project is: Yolkkh, The Story of My People. With this project I present a series of scarves each one bearing an illustrated scene in order to tell a story – my story and the story of the Noxci people. Noxci are the people who are referred to as “Chechens” by Russians and are generally known by that title. As a Muslim, I have witnessed the way Western media tend to dehumanize my community. In order to contrast this dehumanizing process, I thought that telling the story of my family would help reverse Islamophobic tendencies and raise …

Coaching Paraeducators To Accurately Record Student Response Data During Direct Instruction, Paige J. Carter Phd

Theses and Dissertations

Paraeducators serving students with disabilities outnumber special education teachers in the United States (Stewart, 2019; U. S. Department of Education et al., 2018). Paraeducators regularly provide instruction without the benefit of regular and effective training. One of the duties associated with instruction is the collection of instructional data. The purpose of this study was to examine a combination of training and coaching on the accuracy of recording student responses. In addition, a teacher-as-coach model was examined for feasibility with existing time and resources. A multiple baseline across participants design was planned. Special education teachers and paraeducators at a public separate …

Why We Follow Celebrities: An Examination Of Parasocial Interaction And Fan Engagement In A Celebrities’ Social Media Pages, Mohammed A. Alasmari

Theses and Dissertations

Social media sites have become essential for organizations and celebrities, allowing them to build relationships and interact with fans. Previous research found openness and perceived interactivity to improve social media engagement. The current study used the concepts of parasocial interactions and relationships to enhance the current knowledge of how celebrities influence their followers through Twitter. The study looked at perceived openness, perceived interactivity, and media engagement in relation to parasocial interaction and relationships using the Qualtrics survey response from 905 participants on Fayez Al-Malki’s Twitter page. The results indicated that both celebrities' and followers' posts employed openness and perceived interactivity, …

The Double Burden Of Racial Discrimination In Daily-Life Moments: Increases In Negative Emotions And Depletion Of Psychosocial Resources Among Emerging Adult African Americans, Nataria T. Joseph, Laurel M. Peterson, Heather Gordon, Thomas W. Kamarck

Psychology Faculty Research and Scholarship

Objective: Racial discrimination is a common experience for African Americans, but no research has examined how discrimination reported in daily-life moments influences concurrent negative emotions and psychosocial resources. Method: Emerging adult African Americans (N = 54) reported hourly on momentary racial discrimination, negative emotions, and psychosocial resources across two days. Results: Controlling for past discrimination and trait emotion, momentary racial discrimination was associated with greater negative emotions and lower psychosocial resources (ps < .05). The relationship between momentary racial discrimination and negative emotions was stronger among individuals residing in areas with fewer African Americans (simple slope p < .0001). The relationship between momentary racial discrimination and psychosocial resources was stronger among individuals reporting greater past discrimination (simple slope p < .0001). Vicarious discrimination (exposure to discrimination experienced by another person) was associated with higher negative emotions, p < .01, but not with psychosocial resources. Conclusion: These results are the first to demonstrate that personal and vicarious racial discrimination are associated with negative emotions and lower coping resources …

Results

Better adolescent HRQOL was associated with better glycemic control. Better preadolescent HRQOL was associated with better parent HRQOL. Non-White adolescents had worse HRQOL than White …

Integrating Cost As A Decision Variable In Wargames, Joshua N. Reese, Jonathan D. Ritschel, Brent T. Langhals, Ryan D. Engle

Faculty Publications

The US military can no longer afford to be reactive, leaving critical cost analyses to the months and years following operations or full-scale conflicts. By leveraging cost in wargaming as part of the Joint planning process, DOD can provide Congress and the American taxpayers a range of potential costs associated with various military engagements that reflect fiscal and operational realities.

“No Queremos Quedar Mal”: A Qualitative Analysis Of A Boundary Setting Training Among Latina Community Health Workers., Luis R. Alvarez-Hernandez, J. Maria Bermudez, Pamela Orpinas, Rebecca Matthew, Alejandra Calva, Carolina Darbis

School of Social Work Faculty Publications

Community health workers (CHWs)—or promotoras de salud in Spanish—have successfully addressed the health needs of Latinx and immigrant populations. However, for promotoras, setting boundaries is particularly difficult given challenges like residing in the same communities as their participants. The purpose of this study was to describe the development and impact of a boundary setting training to support the emotional well-being of immigrant promotoras. The training (four 1-hr sessions) was informed by social cognitive theory and a Chicana feminist framework. The promotoras who participated in the training helped create Lazos Hispanos, a community-based participatory research (CBPR) study and CHW …

Mitral Valve Repair Complicated By Left Circumflex Coronary Artery Occlusion: The Vital Role Of The Anesthesiologist, Andres Bacigalupo Landa, Jason Hoyos, Jayanand D'Mello

Faculty, Staff and Students Publications

The anatomical relationship between the mitral valve and the left circumflex coronary artery places this vessel at risk for occlusion during mitral valve repair or replacement. In view of the potential high morbidity and mortality of this complication, the anesthesiologist has a vital role in its prompt diagnosis. We present the case of a 47-year-old man who underwent a minimally invasive mitral valve repair, which was complicated by left circumflex coronary artery occlusion.

Faculty, Staff and Students Publications

Aims: We describe a new aortic arch dissection (AcD) classification, which we have called the Fuwai classification. We then compare the clinical characteristics and long-term prognoses of different classifications.

Methods: All AcD patients who underwent surgical procedures at Fuwai Hospital from 2010 to 2015 were included in the study. AcD procedures are divided into three types: Fuwai type Cp, Ct, and Cd. Type Cp is defined as the innominate artery or combined with the left carotid artery involved. Type Cd is defined as the left subclavian artery or combined with the left carotid artery involved. All other AcD surgeries are …

Single-Dose Del Nido Cardioplegia Compared With Standard Cardioplegia During Coronary Artery Bypass Grafting At A Veterans Affairs Hospital, Michael R Reidy, Ernesto Jimenez, Shuab Omer, Lorraine D Cornwell, Sabrina X Runbeck, Ourania Preventza, Gabriel Loor, Todd K Rosengart, Joseph S Coselli

The Texas Heart Institute Journal

Del Nido cardioplegic solution (DNC), used chiefly in pediatric patients, rapidly induces prolonged cardiac arrest during cardiac surgery. To determine whether surgical outcomes after coronary artery bypass grafting in a United States military veteran population differed when DNC was used instead of our standard Plegisol cardioplegia, we retrospectively reviewed 155 consecutive operations performed from July 2016 through June 2017. Del Nido cardioplegia was used to induce cardiac arrest in 70 patients, and Plegisol in 85. Compared with the Plegisol group, the DNC group had a shorter mean cardiopulmonary bypass time (96.8 vs 117 min; P48 hours, atrial fibrillation, tracheostomy, reintubation, …

Papillary Fibroelastoma In Differential Diagnosis Of Left Atrial Appendage Masses, Anthony Alozie, Annette Zimpfer, Andreas Erbersdobler, Felix G Meinel, Pascal M Dohmen, Alper Öner

The Texas Heart Institute Journal

Papillary fibroelastomas are benign tumors that usually originate from cardiac valves but may have other endocardial origins. We report the cases of 2 patients in whom left atrial appendage masses were initially diagnosed as thrombus. They were treated for embolic stroke and their symptoms resolved; however, their left atrial appendage masses did not regress. After surgery, histologic analysis of the resected masses revealed papillary fibroelastoma in both cases. We discuss the diagnostic and therapeutic dilemmas encountered in patients with papillary fibroelastomas and cardiac masses other than thrombus.

Benign Metastasizing Leiomyoma In The Heart Of A 45-Year-Old Woman, Mohamad Karnib, Isaac Rhea, Robin Elliott, Saneka Chakravarty, Sadeer G Al-Kindi

The Texas Heart Institute Journal

We report a rare case of benign metastasizing leiomyoma in the heart of a 45-year-old woman 2 years after a uterine leiomyoma had been discovered during hysterectomy. Computed tomograms at presentation showed a large mixed cystic mass in the pelvis and bilateral lung nodules suggestive of metastatic disease. A large cardiac mass, attached to the chordae of the tricuspid valve and later shown to be histopathologically consistent with uterine leiomyoma, was successfully resected through a right atriotomy. This case suggests that benign metastasizing leiomyoma should be considered in the differential diagnosis of right-sided cardiac tumors.

Cerebellar Coordination Of Neuronal Communication In Cerebral Cortex, Samuel S Mcafee, Yu Liu, Roy V Sillitoe, Detlef H Heck

Duncan NRI Faculty and Staff Publications

Cognitive processes involve precisely coordinated neuronal communications between multiple cerebral cortical structures in a task specific manner. Rich new evidence now implicates the cerebellum in cognitive functions. There is general agreement that cerebellar cognitive function involves interactions between the cerebellum and cerebral cortical association areas. Traditional views assume reciprocal interactions between one cerebellar and one cerebral cortical site, via closed-loop connections. We offer evidence supporting a new perspective that assigns the cerebellum the role of a coordinator of communication. We propose that the cerebellum participates in cognitive function by modulating the coherence of neuronal oscillations to optimize communications between multiple …

Purpose: This preliminary case series investigated the effects of biofeedback intervention for residual rhotic errors delivered within a modified challenge point framework. In the challenge point framework, practice difficulty is adaptively adjusted with the goal of enhancing generalization learning. This study more specifically evaluated the feasibility of a computer-mediated implementation of challenge point treatment for rhotic errors using a custom open-source software, the Challenge Point Program.

Method: Participants were five native English speakers, ages 7;3–15;5 (years; months), who had established but not generalized correct rhotic production in previous treatment; overall treatment duration was flexible. Treatment incorporated either electropalatographic …

Ideology And Institutions In The Evolution Of Capital, Katharina Pistor

Faculty Scholarship

In Capital and Ideology, Thomas Piketty poses the intriguing thesis that ideology, or ideas about how society should be governed, is a powerful determinant for how society will be governed-as long as we take advantage of historical switch points. In this review essay I challenge this thesis by pointing out that many powerful ideas have run aground because of countervailing institutional arrangements. Oftentimes, they are leftovers from earlier times that precede the change and are now strategically employed for reconstituting private wealth. Clearly, ideology and institutions are deeply intertwined. I credit Piketty for putting ideology on the map of …

Drivers Of Health Policy Adoption: A Political Economy Of Hiv Treatment Policy, Matthew M. Kavanagh, Kalind Parish, Somya Gupta

Georgetown Law Faculty Publications and Other Works

Why do some countries rapidly adopt policies suggested by scientific consensus while others are slow to do so? Through a mixed methods study, we show that the institutional political economy of countries is a stronger and more robust predictor of health policy adoption than either disease burden or national wealth. Our findings challenge expectations in scholarship and among many international actors that policy divergence is best addressed through greater evidence and dissemination channels. Our study of HIV treatment policies shows that factors such as the formal structures of government and the degree of racial and ethnic stratification in society predict …

Complicity And Lesser Evils: A Tale Of Two Lawyers, David Luban

Georgetown Law Faculty Publications and Other Works

Government lawyers and other public officials sometimes face an excruciating moral dilemma: to stay on the job or to quit, when the government is one they find morally abhorrent. Staying may make them complicit in evil policies; it also runs the danger of inuring them to wrongdoing, just as their presence on the job helps inure others. At the same time, staying may be their only opportunity to mitigate those policies – to make evils into lesser evils – and to uphold the rule of law when it is under assault. This Article explores that dilemma in a stark form: …

Constitutional Skepticism And Local Facts, Louis Michael Seidman

Georgetown Law Faculty Publications and Other Works

Are written constitutions evil? In his new book, Constitutional Idolatry and Democracy, Brian Christoper Jones argues that they are. He claims that written constitutions fail to unite societies, degrade democratic engagement, and obstruct necessary constitutional maintenance. This review of his book argues that he is mostly right about the effects of the American Constitution, but that the effects of other constitutions will vary depending upon local facts.

Arthur Linton Corbin, Gregory Klass

Georgetown Law Faculty Publications and Other Works

This chapter on Arthur Linton Corbin will appear in the forthcoming collection, Scholars of Contract Law. The chapter provides a brief summary of Corbin’s life, then discusses five topics: Corbin’s Socratic approach to the classroom and his introduction of the caselaw method at Yale; Corbin’s analytic approach, which was inspired by Hohfeld and is illustrated by Corbin’s definitions of “contract” and “consideration”; Corbin’s evolutionary theory of the common law, his understanding of the relationship between law and social mores, and his insistence that legal rules always be treated as mere “working rules”; Corbin’s occasional appeal, despite his general aversion …

Power Washing Pulmonary Alveolar Proteinosis, Tiana R Endicott-Yazdani, Gary S Schwartz, Haiying Zhang, Randall L Rosenblatt, Puneet S Garcha

Faculty, Staff and Students Publications

Pulmonary alveolar proteinosis is an uncommon cause of insidious onset shortness of breath and hypoxemia. It is caused by an accumulation of surfactant within the alveoli. Left untreated, it can be fatal. Standard-of-care treatment is whole-lung lavage; however, in severe cases, the associated hypoxemia can be profound and single-lung ventilation would not be tolerated, potentially preventing a lifesaving treatment. Single cases using veno-venous extracorporeal membrane oxygenation to perform whole-lung lavage have been reported. Here we describe three patients with severe pulmonary alveolar proteinosis who were successfully treated with whole-lung lavage using veno-venous extracorporeal membrane oxygenation for oxygenation support.
