Plume Characterization Of Electric Solid Propellant Pulsed Microthrusters, Matthew S. Glascock, Joshua L. Rovey, Shae Williams, Jason Thrasher

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Electric solid propellants are an attractive option for propulsion because they are ignited only by an applied electric current. This leads to capabilities such as on-demand throttling and reignition in chemical combustion operation, and it lends itself to application in electric propulsion. In this work, the plasma plume created by electric solid propellant pulsed micro thrusters is investigated using a nude Faraday probe, a triple Langmuir probe, and residual gas analysis. The thrusters are tested at a vacuum level of 2 x 10-5torr. Results indicate an average plume electron temperature of 1.7 eV and a density of 1011 to 1014cm-3. …

Why New Corporate Law Arises: Implications For The 21st Century, Robert Thompson

Georgetown Law Faculty Publications and Other Works

The corporate governance landscape is much different than a generation ago. Independent directors now hold a great majority of all board seats, institutional shareholders hold a supermajority of all shares in public corporations, and activist shareholders have become a recurring player in entity governance. In turn, other corporate stakeholders express increasing concern about shareholders’ use of their power for selfish reasons and the perceived pernicious impact of shareholder wealth maximization as a guide for corporate law. This chapter, part of a book on “The Corporate Contract in Changing Times” asks: Why does corporate law change and how it might change …

Beyond The Rct: Integrating Rigor And Relevance To Evaluate The Outcomes Of Domestic Violence Programs, Deborah Epstein, Lisa A. Goodman, Cris M. Sullivan

Georgetown Law Faculty Publications and Other Works

Programs for domestic violence (DV) victims and their families have grown exponentially over the last four decades. The evidence demonstrating the extent of their effectiveness, however, often has been criticized as stemming from studies lacking scientific rigor. A core reason for this critique is the widespread belief that credible evidence can derive only from research grounded in randomized control trials (RCTs). Although the RCT method has its strengths, we argue that it is rarely an optimal—or even a possible—approach for evaluating multifaceted DV programs. This article reviews the reasons that RCT is a poor fit for such programs and argues …

Promising Digital Practices For Nondominant Learners, Kathy Bussert-Webb, Laurie A. Henry

Bilingual and Literacy Studies Faculty Publications

This case study took place during an after-school program in a public Texas school district along the U.S./Mexico border. We explore a focal participant’s technology access and use as part of our larger digital literacy research. We asked: What in- and out-of-school digital literacy skills, access, and experiences did Robot Boy (pseudonym) possess? How did he behave as a rhizome? Overarching theoretical frameworks were postmodernism and New Literacy Studies; within these theories, we focused on rhizomic principles and digital literacies. This research is part of a larger mixed methods research study (Bussert-Webb & Henry, 2016) focused on an exploration of …

What Students Do With Words: Language Use And Communicative Function In Full And Partial Immersion Classrooms, Katherine Christoffersen

Writing and Language Studies Faculty Publications

Over the past 35 years, language immersion programs have been steadily increasing in number throughout the U.S. The popularity of these diverse, linguistically complex educational programs has led to a rather extensive body of research on language immersion and dual language contexts. Research, however, has thus far focused primarily on the quantification of language use (the amount of target language versus first language use) in different settings and with different interlocutors. Very few studies have probed the interesting and significant sociolinguistic question of what students ‘do’ with languages in the classroom. The present study fills this research gap by investigating …

Spanish Speaking Institutions And Language Assimilation In The Rio Grande Valley, Alexandre Couture Gagnon, Carlos Gutierrez-Mannix

Political Science Faculty Publications

The Rio Grande Valley in Texas, situated on the US-Mexico border, has a population of more than one million, of which more than 90% is of Latino descent.1 However, no public institutions formally function in Spanish, thus inhibiting institutional completeness2 and challenging long-term preservation of the language. Why does this population of Latino descent not demand Spanish-language service? Contrary to traditional research on institutional completeness, we consider institutions as the dependent variable and argue that the absence of institutions reflects the perception, within the population, of inferior status ascribed to Spanish when compared to English.

"Hail Mary, Full Of Haze": Physicalism And The Knowledge Argument, Jesse R. Powell

Honors College Theses

This project aims to provide a clear and compelling reason for rejecting dualism with respect to the mind, by undermining the support dualist positions receive from so-called knowledge arguments. In particular, I will show the error present in the many forms of what is variously called the “Mary’s Room” or “Mary the Brilliant Color Scientist” thought experiment.

The Dragon’S Flight To The Tropics: China’S Involvement In The Caribbean, Kellie O'Boyle

Honors College Theses

In 2008, the United States experienced an economic crisis that ultimately caused it to take a step back from its involvement in the Caribbean, in particular. This vacuum left by the United States was swiftly filled by China, which shifted the balance of power in the region and provided China a strategic foothold. This event allowed China to expand its influence, as well as challenge US interests through the use of soft power such as trade and investments in infrastructure. While this symbiotic relationship benefits both parties, there is usually a trade inequality in China’s favor. China’s traditional use of …

Gloria Anzaldúa’S El Mundo Zurdo: The Necessity Of A Historical Assessment, Malik Raymond

Honors College Theses

This thesis revolves around Chicana lesbian feminist Gloria Anzaldúa and one of her more important theories, El Mundo Zurdo. El Mundo Zurdo was a theory that focused on the marginalized people and the need for unity amongst them; however, up to this point, no historical analysis has been done on this theory. Through piecing together information from interviews and Anzaldúa’s literature, this thesis serves as a biography of her first forty years of life to address from where the theory came and becomes a bridge to link Anzaldúa to the wider Chicana, Third World feminist, and gay and lesbian …

Lost Boys And Girls: Navigating Experience And Identity During Operation Pedro Pan, Caleb M. Still

Honors College Theses

Over 14,000 unaccompanied children came from Cuba to the United States during Operation Pedro Pan. Once they arrived they were faced with an entirely new living situation and were forced to adapt. One of the remaining similarities to their Cuban home was the Catholic Church. The Church played a significant role in shaping these children’s fluid concept of their ethnic, national, and religious identities. Previous scholarship has not addressed the role of the Church in the program or the issue of the fluidity of identity among these children. This study builds on the existing scholarship and aims to fill in …

Adopting Team-Based Learning For In-Service Teachers: A Case Study, Zachary M. Walker, Toh Guo Zheng, Redante Mendoza, Elise Lee

International Journal for the Scholarship of Teaching & Learning

Team-based learning (TBL) is an instructional pedagogy that has gained recent popularity due to its effectiveness in disciplines such as medicine and business. However, TBL has not been widely adopted in teacher education based on reviews of research and practitioner based literature. The purpose of this case study was to assess the implementation and effectiveness of TBL in a Singapore teaching institute with thirty in-service teachers. Quantitative and qualitative data was collected from teachers about their experience learning through TBL. Research findings revealed that 1) teachers generally perceived TBL to be a positive experience, although several areas for improvement were …

Examining Students’ Self-Perceived Competence And Comfort In An Experiential Play Therapy Counseling Course: A Single Group Pretest-Posttest Investigation, Paulina Flasch, Dalena Taylor, Rikke Nynne Clauber, Edward Robinson Iii

International Journal for the Scholarship of Teaching & Learning

The current study utilized a single-group pretest-posttest design to evaluate students’ self-perceived competence and comfort of using a variety of play therapy techniques and interventions with a range of client populations as a result of taking a one-week intensive course in Play Therapy. In an effort to conduct course evaluation and explore student’s self-perceived comfort and competence related to play therapy the researchers created the Play Therapy Comfort and Competency Survey based on the content of the course. The results indicated statistically significant scores between the pre- and posttest measures, as measured by participants’ self-perceived higher competence and comfort levels …

Not-So-Critical Friends: Graduate Student Instructors And Peer Feedback, Daniel L. Reinholz

International Journal for the Scholarship of Teaching & Learning

Graduate student instructors (henceforth, instructors) play a crucial role in teaching early STEM courses. Thus, professional development for these instructors addresses an urgent need to improve STEM student success. This paper focuses on a semester-long professional learning community in which six mathematics graduate student instructors engaged in regular cycles of peer observation, feedback, and reflection. In contrast to other professional development work, this approach emphasized that instructors give, not just receive, peer feedback. Analyses of post-semester interviews indicated that all instructors enhanced their noticing of students. The interviews also highlighted the challenges of providing critical, supportive feedback.

Predicting Faculty Intentions To Assign Writing In Their Classes, David Trafimow, Lindsay M. Ruckel, Shelly Stovall, Yogesh J. Raut New Mexico State University

International Journal for the Scholarship of Teaching & Learning

Teachers who offer undergraduate courses agree widely on the importance of writing assignments to further undergraduate education. And yet, there is a great deal of variance among teachers in their writing assignments; some teachers assign no writing whatsoever. To determine the variables that influence the decisions of teachers about whether to assign writing, we predicted their intentions to assign writing from attitudes, subjective norms, perceived control, and perceived difficulty pertaining to assigning writing. Zero-order correlations and hierarchical regression analyses implicate attitude and perceived difficulty as the most important predictors of teacher’s intentions to assign writing in two studies. We also …

Affect Matters: When Writing Feedback Leads To Negative Feeling, Amy Rupiper Taggart 2317148, Mary Laughlin

International Journal for the Scholarship of Teaching & Learning

A continuous challenge in the writing classroom is maintaining openness and positivity around feedback. There are myriad factors that influence the felt experience of the feedback process, and the researchers wanted to understand better how students experience and perceive negative moments, as well as what factors remain salient in their minds after the fact. Therefore, we surveyed students nationwide who had taken a writing intensive course to learn about the moments when they were not able to take teacher feedback and use it to revise, as well as the times when they used feedback against their own judgment. Drawing on …

Using A Teaching Philosophy Statement As A Professional Development Tool For Teacher Candidates, Nancy G. Caukin, Thomas M. Brinthaupt

International Journal for the Scholarship of Teaching & Learning

Most new teachers are expected to develop a teaching philosophy statement (TPS). In the present paper, we describe some of the major functions of a TPS and how it can be beneficial to the professional development of teacher candidates. We then describe a case example of a Residency I program and how the features of that program help teacher candidates write an effective TPS. Seventy-three senior-level teacher candidates at a large public, comprehensive southeastern U.S. university participated in the study. At the end of their Residency I semester, they completed a survey in which they rated the importance and influence …

Semi-Analytical Approach For Time-Dependent Load-Settlement Response Of A Jacked Pile In Clay Strata, Lin Li, Jingpei Li, De'an Sun, Weibing Gong

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Mechanical behavior of the soil around a jacked pile changes significantly during pile installation and subsequent consolidation. Hence, an axially loaded jacked pile exhibits apparent time-dependent bearing performance after pile installation. This paper presents a semi-analytical approach to predict the time-dependent bearing performance of an axially loaded jacked pile in saturated clay strata. The effects of pile installation and subsequent consolidation on the changes in mechanical properties of the surrounding soil are modeled by the cavity expansion theory and the radial consolidation theory, respectively. An exponential function-based load-transfer (t-z) curve is employed to describe the nonlinear behavior of the pile-soil …

Well Integrity Assessment Of Monitoring Wells At An Active Co2-Eor Flood, Andrew Duguid, Boyun Guo, Runar Nygaard

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Assessment of well integrity has become more important for CCS and CO₂-EOR as it has become apparent that wells represent the most likely migration pathway for CO₂ to leave a CCS storage unit or a CO₂-EOR reservoir. Although wells represent a migration pathway, they are also the best vehicle for employing technology monitoring CO₂ injection and storage. This contradiction of being a potential migration path and key monitoring technology leads to a need to understand how monitoring wells may be similar or different in comparison to other types of wells with respect to migration …

Analysis Of Ior Pilots In Bakken Formation By Using Numerical Simulation, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai, Mortadha Alsaba

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Bakken is the most productive formation among unconventional plays in North America. This formation has 7.4 billion barrels of recoverable oil. However, the primary oil recovery is still low as 5-10%. Miscible natural gas and carbon dioxide (CO₂) might be the most two potential strategies to improve oil recovery in such complex play. In this study, some of the IOR pilots which have been conducted in Montana, North Dakota, and South Saskatchewan have been presented. The performance results of these pilots in US-Bakken versus Canadian-Bakken have been compared. Moreover, the reasons beyond the successful IOR pilots in Canadian-Bakken …

Integrating Microgels And Low Salinity Waterflooding To Improve Conformance Control In Fractured Reservoirs, Ali Alhuraishawy, Mingzhen Wei, Baojun Bai, Abdullah Almansour

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The recovery from fractured reservoirs is usually low. The areal heterogeneity is one result of the fractured reservoir. Low salinity waterflooding (LSWF) and preformed particle gel (PPG) have recently investigated by some researchers. The main objective of this study was to determine whether the combining technologies can improve conformance control in fractured sandstone reservoirs. Semi-transparent five-spot models made of sandstone cores and acrylic plates were built. The effect of low salinity waterflooding on oil recovery was studied. Models were designed with three parallel open fractures. Sodium chloride (1.0, 0.1, 0.01, and 0.001 wt. % NaCl) were used for brine flooding …

Updated Criterion To Select Particle Size Distribution Of Lost Circulation Materials For An Effective Fracture Sealing, Mortadha Alsaba, Mohammed F. Al Dushaishi, Runar Nygaard, Olav Magnar Nes, Arild Saasen

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

This paper presents a new criterion to select particle size distribution (PSD) for an effective fracture sealing. The method was developed based on a comprehensive laboratory investigation that was conducted to determine the relationship between effectiveness of different lost circulation material (LCM) treatments in terms of the sealing efficiency and PSD. The results were compared with the current selection methods, which were developed to enhance the bridging capabilities for drill-in fluid, to investigate their applicability in designing effective treatments for fracture sealing. A statistical investigation was carried out to develop new criteria that suggest PSD based on the expected fracture …

Unbundling Freedom In The Sharing Economy, Deepa Das Acevedo

Case Law, Adam N. Steinman

Articles

Although case law plays a crucial role in the American legal system surprisingly little consensus exists on how to determine the "law" that any given "case" generates Lawyers judges and scholars regularly note the difference between holdings and dicta and between necessary and unnecessary parts of a precedentsetting decision but such concepts have eluded coherent application in practice There remains considerable uncertainty about which aspects of a judicial decision impose prospective legal obligations as a matter of stare decisis and to what extentThis Article develops a counterintuitive but productive way to conceptualize case law the lawmaking content of a judicial …
