Remnants Of Educational Leadership And Desegregation Etched In The Memories Of Black Educational Leaders: An Oral History, Janice Barge Clarke

USF Tampa Graduate Theses and Dissertations

In this study the experiences of Black (a.k.a. African Americans/ Negroes) educationalleaders were explored focusing on the period during the transition to a more desegregated public- school setting in the state of Florida. Using retrospective storytelling and reflections of ‘leading’ during desegregation, the lived experiences of those in educational leadership roles were captured in the form of oral histories and analyzed using critical race theory. The effects of desegregation is recounted from their vantage point, from the dissolution of the ‘all Black’ schools to the impact it had on the communities. The research question was: What are the stories told …

Creating And Implementing A Principal Investigator Tool Kit For Enhancing Accrual To Late Phase Clinical Trials: Development And Usability Study., Kristin A Higgins, Alexandra Thomas, Nancy Soto, Rebecca Paulus, Thomas J George, Thomas B Julian, Sharon Hartson Stine, Merry Jennifer Markham, Maria Werner-Wasik

Kimmel Cancer Center Faculty Papers

BACKGROUND: Accrual to oncology clinical trials remains a challenge, particularly during the COVID-19 pandemic. For late phase clinical trials funded by the National Cancer Institute, the development of these research protocols is a resource-intensive process; however, mechanisms to optimize patient accrual after trial activation are underdeveloped across the National Clinical Trial Network (NCTN). Low patient accrual can lead to the premature closure of clinical trials and can ultimately delay the availability of new, potentially life-saving therapies in oncology.

OBJECTIVE: The purpose of this study is to formally create an easily implemented tool kit of resources for investigators of oncology clinical …

A rapid qualitative assessment of division-level capacity identified successes and bottlenecks in providing EHNS- and COVID-19-related services during the first months of the pandemic in Bangladesh. Semi-structured interviews were held with the Health and Family Planning Divisional Directors of the Ministry of Health and Family Welfare. The Primary Health Care System Framework guided the content analysis, focusing on (i) service delivery, (ii) communication and community …

Exploring The Efficacy Of Kinetic Facades In A Northern Climate [Rochester, Ny], George Ray-Offor

Theses

The quality of a building is greatly influenced by the design of its facades. Essentially, it serves as a barrier between an interior area and the outside environment. This implies that the façade serves as a conduit for communication between the activities going] on within and outside the building. Façade design has an impact on the appearance of a structure, and consequently on the perception of its users. The adoption of Kinetic façades may dramatically reduce energy consumption in buildings, which accounts for around one-third of total energy consumption worldwide. This thesis will investigate a computational technique to improve building …

Biophilic Architecture Used To Improve Patient Outcomes And Recovery In Behavioral Health Centers, Heidy M. Valdez

Theses

Humans naturally seek adventure and the outdoors. Currently, US institutions that care for people with chronic illnesses, severe injuries, and mental health conditions often exist in neutral spaces with little to no natural elements. Because this does not promote patient happiness, patient recovery time tends to be longer. These institutions are usually not pleasant for patients or their relatives and are seen as negative spaces by the public, which should not be the case. Typical design elements include windows with thick daylight-blocking mullions to ensure no patient tries to hurt themselves, small and dark rooms, white walls, and no private …

Integrated Framework For Analyzing Clean Energy Technology Subsidies, Tiruwork Berhanu Tibebu

Theses

Renewable energy technologies can significantly reduce fossil fuel consumption and greenhouse gas emissions associated with the energy sector. In US, both federal and state governments have implemented numerous policies and programs to support these technologies. But these policies require a substantial amount of public spending. In this study, an integrated model to identify optimal subsidy schedules for clean energy technologies that maximize social benefits less subsidy costs is developed. The national flexible optimal subsidy schedule for residential solar PV begins at $585/kW and declines to zero in 14 years. An alternative analytical model is also presented to analyze technological features …

Study Of Constitutive Model Of Frozen Sandstone Damage Based On Weibull Distribution, Yi Ming, Zhao Tao, Ma Feifei, Wang Lei, Yuan Chao

Coal Geology & Exploration

Abstract: The deformation and destruction characteristics of frozen rock is a basic mechanical problem encountered during the construction using the freezing method. Under the action of load, the mechanical characteristics and deformation characteristics are greatly different for the rock with different freezing temperatures, which significantly affects the safety and stability of the freezing wall. Therefore, the study of the damage constitutive relation of the frozen rock is significant for instructing the freezing method design and construction. In order to analyze the whole process of the frozen rock deformation and destruction under load action, the Weibull distribution was adopted to describe …

Experimental Study On Power Matching Of Modular Double Pumping Stations Of Tunnel Drilling Rig, Lu Feifei, Fan Dong, Tian Hongliang

Coal Geology & Exploration

In order to solve the problems of heavy weight, relocation and transportation of the power pumping station of tunnel drilling rigs, it is proposed to divide the pumping station through modular design, and adopt the solution of small-displacement, dual-power and dual-pump confluence, effectively reducing the transportation size and weight of a single pump station. A single-pump station or a double-pump confluence is chosen according to the working conditions to improve the flexibility of the drilling rig and reduce energy consumption. The load-sensing system has the advantages of energy saving, good load adaptability, and convenient speed regulation. However, when the dual-load-sensing …

Why America’S Army Can’T Win America’S Wars, John A. Nagl

The US Army War College Quarterly: Parameters

Since achieving victory in World War II, the United States military has a less than enviable combat record in irregular warfare. Through a detailed historical analysis, this article provides perspective on where past decisions and doctrines have led to defeat and where they may have succeeded if given more time or executed differently. In doing so, it provides lessons for future Army engagements and argues that until America becomes proficient in irregular warfare, our enemies will continue to fight us at the lower levels of the spectrum of conflict, where they have a good chance of exhausting our will to …

Using Direct Pcr For Disaster Victim Identification Reference Samples, Mary Habib

Student Theses

Forensic genetic testing is an important tool for the identification of victims after a mass fatality event but degradation of remains, presence of PCR inhibitors, and limited amounts of sample can make testing difficult. Standard protocols typically include extraction of genetic material from recovered post-mortem samples, and from ante-mortem reference samples or families of a missing person. This is a time-consuming and laborious process and may result in the loss of trace amounts of DNA available for amplification. Incorporating workflows that bypass the extraction step and directly amplify recovered DNA for short tandem repeat (STR) profile generation has the potential …

Multi-Omics Analysis Reveals Metabolic And Epigenetic Changes Associated With Macrophage Polarization, Mark L. Sowers, Hui Tang, Vipul K. Singh, Arshad Khan, Abhishek Mishra, Blanca I. Restrepo, Chinnaswamy Jagannath, Kangling Zhang

School of Medicine Publications

Macrophages (MФ) are an essential immune cell for defense and repair that travel to different tissues and adapt based on local stimuli. A critical factor that may govern their polarization is the cross-talk between metabolism and epigenetics. However, simultaneous measurements of metabolites, epigenetics, and proteins (phenotype) has been a major technical challenge. To address this, we have developed a novel triomics approach using mass spectrometry to comprehensively analyze metabolites, proteins, and histone modifications, in a single sample. To demonstrate this technique, we investigated the metabolic-epigenetic-phenotype axis following polarization of human blood-derived monocytes into either 'pro-inflammatory M1'- or 'anti-inflammatory M2-' MФs. …

Optical Redox Imaging Of Ex Vivo Hippocampal Tissue Reveals Age-Dependent Alterations In The 5xfad Mouse Model Of Alzheimer's Disease, He N. Xu, Sarah Gourmaud, Allison Podsednik, Xiaofan Li, Huaqing Zhao, Frances E. Jensen, Delia M. Talos, Lin Z. Li

School of Medicine Publications

A substantial decline in nicotinamide adenine dinucleotide (NAD) has been reported in brain tissue homogenates or neurons isolated from Alzheimer's disease (AD) models. NAD, together with flavin adenine dinucleotide (FAD), critically supports energy metabolism and maintains mitochondrial redox homeostasis. Optical redox imaging (ORI) of the intrinsic fluorescence of reduced NAD (NADH) and oxidized FAD yields cellular redox and metabolic information and provides biomarkers for a variety of pathological conditions. However, its utility in AD has not been characterized at the tissue level. We performed ex vivo ORI of freshly dissected hippocampi from a well-characterized AD mouse model with five familial …

Modelling The Thermoelectric Properties Of Cement-Based Materials Using Finite Element Method And Effective Medium Theory, Lorenzo Stella, Conrad Johnston, Javier Troncoso, Piotr Chudzinski, Esther Orisakwee, Jorge Kohanoff, Ruchita Jani, Niall Holmes Dr., Brian Norton, Xiaoli Liu, Ming Qu, Hongxi Yin, Kazuaki Yazawa

Conference papers

Because of the thermoelectric (TE) effect (or Seebeck effect), a difference of potential is generated as a consequence of a temperature gradient across a sample. The TE effect has been mostly studied and engineered in semiconducting materials and it already finds several commercial applications. Only recently the TE effect in cement-based materials has been demonstrated and there is a growing interest in its potential. For instance, a temperature gradient across the external walls of a building can be used to generate electricity. By the inverse of the TE effect (or Peltier effect), one can also seek to control the indoor …

Coal Geology & Exploration

The technological concept of sand fracturing at the high pressure side is proposed against the present situation where the coal mine downhole operation space is small, the power and water supply capacities are limited, and the surface sand fracturing equipment cannot be applied directly in the coal mine downhole. On the basis of the principle of sand mixing and carrying through hydrodynamic impact, the continuous hydraulic sand fracturing equipment at the high pressure side was developed. Such equipment requires no external power source for sand mixing. It forms cyclone impact through the changes in the flow regime and flow field …
