Endobariatric Procedures For Obesity: Clinical Indications And Available Options., Hemant Goyal, Jonathan Kopel, Abhilash Perisetti Md, Rupinder Mann, Aman Ali, Benjamin Tharian, Shreyas Saligram, Sumant Inamdar

Other Specialties

Obesity remains a growing public health epidemic that has increased healthcare costs and related comorbidities. Current treatment guidelines encourage a multidisciplinary approach starting from patient selection, interventions, and long-term follow-up to maintain weight loss. However, these conservative interventions are largely ineffective at reducing body weight due to low adherence to the treatment regimen. Recently, endoscopic bariatric therapies have become an attractive alternative to traditional invasive bariatric surgeries due to their improved efficacy, safety, and cost-effectiveness. Endoscopic bariatric therapies include intragastric balloon placement, endoscopic sleeve gastroplasty, gastric bypass revision, and aspiration therapy. These procedures fall into two separate categories depending on …

The Missing D In U.S. Foreign Relations Law, David H. Moore Jan 2021

The Missing D In U.S. Foreign Relations Law, David H. Moore

Faculty Scholarship

United States foreign relations law once subsisted on the outskirts of constitutional and international law. Now a recognized field of scholarship in its own right, foreign relations law addresses some of the most important questions of our time, such as whether the President may unilaterally conduct strikes against Iran or withdraw from the Paris Climate Agreement. For all its importance, however, U.S. foreign relations law has developed with blinders on. U.S. foreign policy embraces at least three Ds: defense, diplomacy, and development. Yet foreign relations law scholarship has approached the critical questions of the field almost exclusively through the lens …

Dignity And Discrimination, Frederick Mark Gedicks Jan 2021

Dignity And Discrimination, Frederick Mark Gedicks

Faculty Scholarship

Delivered as the Dignity in Law Symposium keynote address, this essay surveys uses of “dignity” in U.S. constitutional law, with a focus on conflicts between the dignities attached to citizenship and religious conscience. Parts I and II discuss dignity as state sovereignty and hierarchical status. Part III examines the collision of dignities in the Masterpiece Cakeshop decision. Part IV argues that attention to the public or private nature of the site where religious accommodation is demanded clarifies when accommodation is appropriate, using a house of worship and a government office as illustrations. Part V lists other sites of accommodation and …

Christian Dignity And The Overlapping Consensus, Frederick Mark Gedicks Jan 2021

Christian Dignity And The Overlapping Consensus, Frederick Mark Gedicks

Faculty Scholarship

This Article rejects arguments by Christian leaders, scholars, and others who lament the secularization of the West and urge Christian dignity as the foundation of universal human rights. It argues instead that only a secular conception of dignity free of Christian metaphysics can create an overlapping consensus in support of human rights.

Part I describes the roots of Christian dignity in medieval theology and status. Part II briefly recounts how the Renaissance and Enlightenment re-centered the end of dignity from knowing God to knowing oneself, while the Reformation’s extension of original sin to the intellect left Catholicism as the primary …

Student Engagement In A Remote Language Learning Environment: The Case Of Ukrainian, Olena Sivachenko, Alla Nedashkivska Jan 2021

Student Engagement In A Remote Language Learning Environment: The Case Of Ukrainian, Olena Sivachenko, Alla Nedashkivska

Russian Language Journal

This paper explores student perceptions of engagement in remote first-year, second-year, and third-year Ukrainian as a foreign language courses at a postsecondary institution. It examines student engagement at five levels: behavioral, emotional, cognitive, agentic, and social. This exploration of engagement, using the case of Ukrainian, supports the view of engagement as a multidimensional concept in which the various levels are interconnected and influence one another. The article provides pedagogical advice that is relevant not only to the context of remote instruction.

Service-Provider Virtual Exchange As A Viable Alternative To Face-To-Face Speaking Practice: Data From Second- And Third-Year Russian Learners, Liudmila Klimanova, Valentina Vinokurova Jan 2021

Service-Provider Virtual Exchange As A Viable Alternative To Face-To-Face Speaking Practice: Data From Second- And Third-Year Russian Learners, Liudmila Klimanova, Valentina Vinokurova

Russian Language Journal

In the context of emergency remote language teaching during the pandemic, the biggest challenge for instructors has been to continue providing learners with opportunities to practice speaking and comprehension skills. Service provider virtual exchange (SPVE) platforms, such as Conversifi, Boomalang, TalkAbroad, iTalki, and LinguaMeeting have the potential to enrich the online learning experience by offering paid videoconferencing sessions with native-speaking language coaches at the students’ convenience. Research shows that regular videoconferencing with native-speaking peers may improve speaking ability (Saito and Akiyama 2017) and foster the development of intercultural competence (Tecedor and Vasseur 2020). This paper will discuss a pilot implementation …

Here, There, And Elsewhere: Reimagining Russian Language And Culture Course Syllabi For Social Justice, Thomas Jesús Garza

Russian Language Journal

The past two decades have witnessed enrollments in American colleges and universities for U.S. residents aged 18 to 24 increase from 35 percent in 2000 to 41 percent in 2018. Within this demographic, those identifying in census data as Hispanic/Latinx increased during the same period from 22 to 36 percent, as Black 31 to 37 percent, as Asian 56 to 59 percent, as Indigenous/Native American 16 to 24 percent, and as bi-or multiracial 38 to 44 percent (Hussar et al. 2020, 125). As the student population of higher education in the United States begins to reflect the national demographic portrait …

The Russian Coordinating Conjunctions И And А: Their Meaning, Function, And Pedagogy, Mark J. Elson Jan 2021

The Russian Coordinating Conjunctions И And А: Their Meaning, Function, And Pedagogy, Mark J. Elson

Russian Language Journal

This paper is concerned with the systemic status of the coordinating conjunctions и and а in Contemporary Standard Russian. Most previous treatments of и and а have, without comment, viewed them as minimal syntactic units (i.e., words) defined, for systemic purposes, functionally—as equating or likening in the case of и but contrasting or opposing in that of а. However, these treatments, whether intentionally or unwittingly, have left unattended the possibility that и and а, although syntactic units, are more properly defined grammatically (i.e., are systemically characterized by an invariant grammatical meaning of which their functions are derivative).1 At …

From Error Annotation To Quantitative Analysis: Patterns In Russian Language Learning, Irina Kor Chahine, Ekaterina Uetova Jan 2021

From Error Annotation To Quantitative Analysis: Patterns In Russian Language Learning, Irina Kor Chahine, Ekaterina Uetova

Russian Language Journal

Although learner corpus research has been progressively growing into an independent branch of corpus linguistics, the learner corpus cannot yet fully benefit from corpus analysis methods. This is due to several technical obstacles involving data collection, error annotation, and finally, data processing. When it comes to data collection, compared to corpus linguistics, learner corpus is biased because some of the learner corpora are still collected manually: Optical character recognition (OCR) is not yet sophisticated enough to transform a student’s handwritten copy to a digitized text. This fact significantly slows the collection of learner corpora. Furthermore, typed students’ texts present another …

Excerpt From Ключевые Идеи Русской Языковой Картины Мира: The Breadth Of The Russian Soul, Alexei D. Shmelev, Nicole-Marie Konopelko, Translator, Stephen M. Dickey, Preface

Russian Language Journal

In 2005 a collection of articles appeared under the title Ключевые идеи русской языковой картины мира (‘Key Ideas of the Russian Linguistic Worldview’), authored by Anna A. Zalizniak, Irina B.

Reconstructing Malice In The Law Of Punitive Damages, Marc O. Degirolami Jan 2021

Reconstructing Malice In The Law Of Punitive Damages, Marc O. Degirolami

Scholarly Articles

Punitive damages present two related puzzles. One concerns their object. If they are punitive, their object is to punish tortfeasors. If they are damages, their object is to compensate tort victims. If they are both, the problem is to reconcile these different objects in applying them. A second puzzle involves their subject. Punitive damages are awarded for egregious wrongdoing. But the nature of that egregiousness is nebulous and contested, implicating many poorly understood terms. The two puzzles are connected, because the subject of punitive damages will inform their object. Once we know the type of wrongfulness that punitive damages deal …

True Knowledge Of God Obscured In Mind And Body: Hildegard Of Bingen’S Medical And Religious Understanding Of Adam’S Fall, Minji Lee Jan 2021

True Knowledge Of God Obscured In Mind And Body: Hildegard Of Bingen’S Medical And Religious Understanding Of Adam’S Fall, Minji Lee

Department of Religion Faculty Scholarship and Creative Works

According to Hildegard of Bingen, Cause et Cure or “Causes and Cures” in English, Adam saw God’s full prophesy for the structure of the world and the last day of the world that eventually the humankind will restore the secret knowledge given by God and they will come back to God. Here, the woman’s body works essential as it is not polluted by the first sin and it can save the humankind as the Virgin Mary gave birth to the Christ. The woman’s body became the important tool to restore the hidden knowledge of God as the body could remember …

What Makes Property Liberal?, Adam J. Macleod Jan 2021

What Makes Property Liberal?, Adam J. Macleod

Scholarly Articles

Hanoch Dagan is offering to help an institution that is in the midst of an identity crisis. For many centuries, property has found its identity in service to liberty. Liberty – both broadly construed as a practical ideal and in the technical sense of a Hohfeldian right that is the absence of duty – stood for independence from outside interference and freedom to act upon one’s own plans of action for the use and management of resources, individually and in community with those who share the same common goods. Though many people still think liberty in that sense is important, …

Cyber Trespass And Property Concepts, Adam J. Macleod Jan 2021

Cyber Trespass And Property Concepts, Adam J. Macleod

Scholarly Articles

Access to information is the purpose of the Internet. Ask anyone born after the dawn of the information age; they will tell you that cyberspace is the place to go if one wants to know stuff. On the other hand, many of the people who put stuff on the Internet or on systems connected to the Internet will tell you that, without legal rights to control or block access, people will not have incentives to put on the Internet stuff that is worth knowing. In this tension between access and control, property is generally assumed to be on the side …

Racial Disparities In Liver Disease In The Us: Addressing The High Prevalence Of Hepatitis B Infection In The Apia Community, Lindsey L. Trinh, Lindsey Trinh

Scripps Senior Theses

Chronic liver disease and hepatocellular carcinoma are some of the leading causes of death in the United States, resulting in a number of annual deaths that has only increased over the past several decades. A vast proportion of these liver-related deaths is due to chronic hepatitis B infection, which currently affects approximately 1.2 million people in the US. However, the hepatitis B virus does not affect every racial group in the United States equally: Asian Americans experience a disproportionately high prevalence of HBV infection. In fact, even though the APIA community comprises only 4% of the US population, they account …

Emotion Disclosure In Spanish And English Bilinguals, Maya Cohrssen-Hernandez Jan 2021

Emotion Disclosure In Spanish And English Bilinguals, Maya Cohrssen-Hernandez

Scripps Senior Theses

Previous literature has identified a difference in emotion comprehension and production of bilinguals. This study aimed to explore differences in emotion expression in the first language (L1) and the second language (L2) among Spanish and English bilinguals. The bilingual participants were interviewed and asked to recount two frustrating events, one in their L1 and one in their L2. These interviews were analyzed for the occurrence of four semantic categories: emotion words (with a subcategory of negative emotion words), emotion-laden words, expressive interjections, and intensifiers that strengthen content words. The data indicated that Spanish and English bilinguals both used more emotion …

Deconstructing Social Anxiety: Through Gifs And The Inspiration Of Artists' Books, Ashley Hsieh Jan 2021

Deconstructing Social Anxiety: Through Gifs And The Inspiration Of Artists' Books, Ashley Hsieh

Scripps Senior Theses

My project deconstructs social anxiety through the form of gifs. This is an important issue to address especially now, as it is one the most current stressors for my peers and myself upon returning to school after over a year in quarantine. Although not everyone has had the same experience, there is a large concern for students’ mental health and well-being post-pandemic. Learning how to re-navigate socializing after a year in isolation has been exhausting, physically and mentally, adjusting to places and new faces on campus. My work is composed of a series of three digital gifs that depict different …

Is Parent Report Of Bilingual Children's Language Environment As Valid As We Think?, Gabrielle Zeyl Jan 2021

Is Parent Report Of Bilingual Children's Language Environment As Valid As We Think?, Gabrielle Zeyl

Open Access Master's Theses

Researchers have defined bilingual language proficiency and dominance in different ways for decades; however, to date there is no standard, systematic description used by the scientific community to quantify bilingual children’s language skills. Parent report questionnaires have been regarded as a valid measure of a child’s language skill. The purpose of this study is to explore the validity of parent report of their child’s language use when compared to hand coded audio segments retrieved using the Language ENvironment Analysis (LENA) System. Additionally, this study explores potential differences in the number of conversational turns and amount of child-directed speech between monolingual …

Using A Person-Centered Approach To Explore Patterns Of Ptsd, Sexual Functioning And Sexual Satisfaction In College Women Exposed To Sexual Violence, Alexandra Lipinski

Electronic Theses and Dissertations Archive

Elevated symptoms of posttraumatic stress disorder, impairment in sexual function, and decreased sexual satisfaction are common among female survivors of sexual violence. Although these symptoms frequently co-occur, little is known regarding whether patterns of symptom comorbidity exist across these conditions. The present study identified empirically-derived profiles of posttraumatic stress disorder symptoms and domains of sexual function and satisfaction among 348 college women who had experienced sexual violence. A four-profile solution was identified. The first profile, Resilient (RES), was characterized by low severity of PTSD and sexual functioning complaints. A second profile, Sexual Distress (SEXDISS), was characterized by greatest endorsement of …

Multivariate Analysis For Understanding Cognitive Speech Processing, Md Sultan Mahmud Jan 2021

Multivariate Analysis For Understanding Cognitive Speech Processing, Md Sultan Mahmud

Electronic Theses and Dissertations Archive

Categorical perception (CP) of audio is critical to understand how the human brainperceives speech sounds despite widespread variability in acoustic properties. Most studiesthat examine cognitive speech processing have applied methodological approaches that focuson specific or a set of brain regions. Departing from hypothesis-driven approaches, in thisdissertation, we proposed multivariate data-driven approaches to identify the spatiotemporal(i.e., when in time and where in the brain) and spectral (i.e., frequency-band power levels)characteristics of auditory neural activity that reflects CP for speech (i.e., differentiatesphonetic prototypes from ambiguous speech sounds). We recorded 64-channel EEG aslisteners rapidly classified vowel sounds along an acoustic-phonetic continuum. We usedparameter …
