Electron Mobility And Velocity In Ai 0.45 Ga 0.55 N-Channel Ultra-Wide Bandgap Hemts At High Temperatures For Rf Power Applications, Hansheng Ye, Mikhail Gaevski, Grigory Simin, Asif Khan, Patrick Fay

Faculty Publications

Ultra-wide bandgap AlGaN has attracted recent attention as a promising channel material for next-generation high electron mobility transistors (HEMTs) for RF power due to its high critical field, excellent transport properties, and potential for operation in extreme environments. However, the effects of temperature on the transport properties are not fully understood. Here, Al0.62Ga0.38N/Al0.45Ga0.55N HEMTs have been fabricated and characterized up to 150 °C at DC and RF to evaluate the effect of temperature on electron mobility and carrier velocity. Measured results indicate that both mobility and carrier velocity exhibit modest dependence on …

Structural Analysis Of Code-Switching In Tanzanian Swahili-English Online Telecom Adverts, Emmanuel Ilonga Dr Mar 2022

Structural Analysis Of Code-Switching In Tanzanian Swahili-English Online Telecom Adverts, Emmanuel Ilonga Dr

Journal of Humanities and Social Sciences

This study analyses structural configurations of code-switching from Swahili-English online business-related advertisements in Tanzania. The study uses advertisements disseminated by telecom corporations on Facebook. Through the matrix language frame (MLF), and the 4–M models of code-switching, the study discloses the dominance of Swahili as the matrix language (ML), supplying a relatively higher quantity of content morphemes (CM) in clauses; whilst English becomes the embedded language (EL). The Swahili’s supremacy in larger mixed language structures reflects the higher application of Swahili in day-to-day interactions in Tanzania, while English ‘chips in’ at times. In bundle names, which are phrases in structure, the …

The Recovery Coach: An Intentional, Relational Interventionist As A Response To The Covid-19 Incomplete Grade Trend, Melanie A. Turrano Mar 2022

The Recovery Coach: An Intentional, Relational Interventionist As A Response To The Covid-19 Incomplete Grade Trend, Melanie A. Turrano

Education Doctorate Dissertations

The COVID-19 pandemic exposed many crises in education; fair and just grading was but one. During that tumultuous time, colleges improvised and created many “hold harmless” grading policies to provide empathy and understanding to students as well as to retain students otherwise negatively impacted by the inequities in their personal lives as well as the socioeconomic digital divide. One “due no harm” policy enacted at the community college where this study occurred was the encouragement of Incomplete (I) grades that prevented student failure in the short term, but traditionally results in long-term failure when the grade of Incomplete (I) converts …

Polarization-Sensitive Optical Responses From Natural Layered Hydrated Sodium Sulfosalt Gerstleyite, Ravi P. N. Tripathi, Xiaodong Yang, Jie Gao

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Multi-element layered materials have gained substantial attention in the context of achieving the customized light-matter interactions at subwavelength scale via stoichiometric engineering, which is crucial for the realization of miniaturized polarization-sensitive optoelectronic and nanophotonic devices. Herein, naturally occurring hydrated sodium sulfosalt gerstleyite is introduced as one new multi-element van der Waals (vdW) layered material. The mechanically exfoliated thin gerstleyite flakes are demonstrated to exhibit polarization-sensitive anisotropic linear and nonlinear optical responses including angle-resolved Raman scattering, anomalous wavelength-dependent linear dichroism transition, birefringence effect, and polarization-dependent third-harmonic generation (THG). Furthermore, the third-order nonlinear susceptibility of gerstleyite crystal is estimated by the probed …

Starvation Diets: The History And Moral Implications Of Prolonging The Lives Of Juvenile Diabetics Before The Discovery Of Insulin, Olivia Thompson Mar 2022

Starvation Diets: The History And Moral Implications Of Prolonging The Lives Of Juvenile Diabetics Before The Discovery Of Insulin, Olivia Thompson

Honors Program: Senior Projects (Public)

This study explores the state of diabetology before Frederick Banting’s discovery of insulin in 1921, when juvenile diabetes was a terminal diagnosis. The widespread misunderstanding of the disease at the hands of physicians and scientists culminated in improper treatments and erroneous anatomical literature about diabetes until the age of discovery in the late 19th and early 20th centuries. More extensively, I examine the controversial work of 20th-century physician Frederick Madison Allen, who attempted to prolong the lives of juvenile diabetics by subjecting them to a rigid starvation diet by way of experimental trials lasting from 1915 to 1922. This diet …

Dancing And Poetry: A Study Of The Whirling Dervish Dance Through Rumi’S Poetry, Tasneem Huq Mar 2022

Dancing And Poetry: A Study Of The Whirling Dervish Dance Through Rumi’S Poetry, Tasneem Huq

Honors Program: Senior Projects (Public)

This exploration investigates the influence of Rumi’s book of poetry, Mathnawi, upon the Sufi practice of the Whirling Dervish dances. It argues that Rumi’s Mathnawi underlies the choreography of the Whirling Dervish dances. Each step of the dance expresses, manifests or embodies themes found in Rumi’s poetry: separation from Unity, ascension, annihilation, and a return to Unity. The thesis introduces this argument, and then discusses historical, theological, and linguistic themes related to Rumi, Sufism, and the Whirling Dervish dances. Following this, the thesis provides a framework that begins with the Neoplatonic theory of emanation grounding Rumi’s poetic thought, followed by …

What Is The Law’S Role In A Recession?, Gabriel V. Rauterberg, Joshua Younger Mar 2022

What Is The Law’S Role In A Recession?, Gabriel V. Rauterberg, Joshua Younger

Law & Economics Working Papers

The last two years have seen astonishing changes to how fiscal and monetary authorities in the developed world manage the economy. In the face of the largest global economic contraction since World War II, governments embarked on massive campaigns of economic stimulus, far outpacing the response to the Global Financial Crisis. Central banks similarly engaged in financial intervention on a scale not seen in eighty years. Over roughly a year, the Federal Reserve alone doubled its asset holdings from around $4 trillion to $8 trillion, making for arguably the most aggressive expansion of the United States’ money supply since the …

Lakshadweep High Propagation And Impacts On The Somali Current And Eddies During The Southwest Monsoon, Paul A. Ernst, Bulusu Subrahmanyam, Corinne B. Trott

Faculty Publications

Climatological eddies in the Arabian Sea (AS), including the Lakshadweep High (LH) and the Great Whirl (GW), play major roles in the regional fluxes of upper ocean properties. For the first time, we apply an eddy tracking algorithm to the LH using altimetric sea surface height observations from 1993 through 2019. We additionally analyze the LH's water mass composition throughout its life cycle using the 1/12° Global eddy resolving physical ocean and sea ice reanalysis (GLORYS12). We observe that the second annual downwelling coastal Kelvin wave's (CKW) arrival during the winter monsoon is primarily responsible for generating the LH. In …

Pathway To The Shoah: The Protocols, "Jewish Bolshevism", Rosenberg, Goebbels, Ford, And Hitler, David M. Crowe Mar 2022

Pathway To The Shoah: The Protocols, "Jewish Bolshevism", Rosenberg, Goebbels, Ford, And Hitler, David M. Crowe

History Faculty Books and Book Chapters

In the dark months after the defeat at Stalingrad in 1943, Joseph Goebbels, the Nazi Party’s strident, virulently anti-Semitic propaganda minister, wrote in his diary that he had “devoted exhaustive study to The Protocols of the Elders of Zion” despite the fact that some argued that “they were not suited to present-day propaganda.” After rereading them, he concluded that “we can use them very well,” since The Protocols were “as modern today as they were when published for the first time.” The same day, May 13, 1943, he met with Hitler, who told his propaganda minister that he thought they …

Macroscale Robust Superlubricity On Metallic Nbb2, Jia Wang, Chang Liu, Kaifei Miao, Kan Zhang, Weitao Zheng, Changfeng Chen Mar 2022

Macroscale Robust Superlubricity On Metallic Nbb2, Jia Wang, Chang Liu, Kaifei Miao, Kan Zhang, Weitao Zheng, Changfeng Chen

Physics & Astronomy Faculty Research

Robust superlubricity (RSL), defined by concurrent superlow friction and wear, holds great promise for reducing material and energy loss in vast industrial and technological operations. Despite recent advances, challenges remain in finding materials that exhibit RSL on macrolength and time scales and possess vigorous electrical conduction ability. Here, the discovery of RSL is reported on hydrated NbB2 films that exhibit vanishingly small coefficient of friction (0.001–0.006) and superlow wear rate (≈10−17 m3 N−1 m−1) on large length scales reaching millimeter range and prolonged time scales lasting through extensive loading durations. Moreover, the measured low resistivity (≈10−6 Ω m) of the …

Suffragettes For Cesareans: "Every Woman Should Have A Choice", Julia B. Imanoff

Theses

Patient choice for caesarean delivery (CD) is complex. This choice poses a challenge to Health Care Providers (HCPs) in terms of resource allocation, economics, and surgical risks. Yet, women's understanding of choice is poorly understood. This study answers the question: how HCPs might understand women's choice for CD? Four primiparous women who chose a CD were recruited. Semi-structured interviews were used to generate data. The interpretation followed a hermeneutic approach.

Secondary School El Teachers’ Classroom Language Proficiency: A Case Study In Bangladesh, Md. Abdur Rouf, Abdul Rashid Mohamed Mar 2022

Secondary School El Teachers’ Classroom Language Proficiency: A Case Study In Bangladesh, Md. Abdur Rouf, Abdul Rashid Mohamed

The Qualitative Report

The study reported here aimed to examine the classroom language proficiency (CLP) of secondary school (SS) English language (EL) teachers in Bangladesh. It is obvious that the EL teachers in a non-native English-speaking context like Bangladesh need to have a very good oral proficiency in the target language (TL) as part of their content knowledge so that learners can take them as models and classroom teaching-learning is effective. Following a multiple case study approach, data were collected from six SS EL teachers as primary informants and four head teachers (HTs), three teacher trainers (TTs), and one curriculum expert (CE) as …

Examining Newcomer Women’S Experiences With Perinatal Care In Ontario, Canada: An Application Of Carspecken’S Critical Ethnographic Method, Jessica Pimienta, Oona St-Amant, Sepali Guruge, Corinne Hart, Cristina Catallo Mar 2022

Examining Newcomer Women’S Experiences With Perinatal Care In Ontario, Canada: An Application Of Carspecken’S Critical Ethnographic Method, Jessica Pimienta, Oona St-Amant, Sepali Guruge, Corinne Hart, Cristina Catallo

The Qualitative Report

This article provides a practical description of Carspecken’s (1996) five-stage critical ethnographic approach entitled “Critical Qualitative Research (CQR).” Situated epistemologically and ontologically in the critical paradigm, this article is an exploration of critical ethnography as an important methodology for shedding light on the discursive culture of perinatal care for newcomer women during the three-month health insurance waiting period in Ontario, Canada. We argue that Carspecken’s approach to critical ethnography is especially instrumental in illuminating the social structures that contribute to health inequities.
