La France Et Le Plurilinguisme: Deux Opposés Qui S'Attirent? Une Étude De L'Enseignement Et De L'Apprentissage Des Langues Étrangères En France., Rachel L. Lorch

Senior Independent Study Theses

Dans un monde si interconnecté que le nôtre, la capacité de bien communiquer et d’échanger de l’information avec des autres devient indispensable. Ainsi, le rôle des langues étrangères dans une variété de sociétés représente un sujet très pertinent. Cette étude se focalise sur l’enseignement et apprentissage des langues étrangères en France. Je voulais savoir si les Français sont vraiment en retard en ce qui concerne l’apprentissage des langues étrangères, surtout en comparaison avec les autres pays d’Europe. Pour répondre à cette question, j’analyse l’histoire de la politique linguistique en France, une variété de documents récents rédigés par les gouvernements français …

The Journey Into Ba: A Phenomenology Of Computer-Mediated Communications, Leticia De Leon, Kevin Freenan

Teaching and Learning Faculty Publications

This study describes the phenomenon of ba within a computer-mediated communications environment, a lived experience shared by the participants through the join.me application. Data were gathered from online meetings with study participants while they were engaged in the process of developing professional development courses specific to their various areas of expertise. Study results indicated that the essence of experience could be reduced to four themes: equalized power structures, affirmed mutual expertise, learner guided mediation, and negotiated concerns.

John Lomax's Southern States Recording Expedition: Brownsville, Texas, 1939, Albert Rodriguez, Rene Torres

Teaching and Learning Faculty Publications

In the spring of 1939, Texas folklorist John Avery Lomax began his Southern States Recording Expedition, focusing primarily on rural Texas and Louisiana. One of the main goals of this and other recording forays into the South and Southwest by Lomax during the 1930s was to document the musical landscape of the nation as it rapidly transformed from a mostly rural-agrarian society to an increasingly urban-industrial one. In part, Lomax wanted to preserve examples of regional folk music before they were "lost" to the growing commercialization of American music. However, Lomax also had another important goal in mind, and that …

The Effect Of Ignoring Statistical Interactions In Regression Analyses Conducted In Epidemiologic Studies: An Example With Survival Analysis Using Cox Proportional Hazards Regression Model, Kristina Vatcheva, Joseph B. Mccormick, Mohammad H. Rahbar

School of Mathematical & Statistical Sciences Faculty Publications

Objective: To demonstrate the adverse impact of ignoring statistical interactions in regression models used in epidemiologic studies.

Study design and setting: Based on different scenarios that involved known values for coefficient of the interaction term in Cox regression models we generated 1000 samples of size 600 each. The simulated samples and a real life data set from the Cameron County Hispanic Cohort were used to evaluate the effect of ignoring statistical interactions in these models.

Results: Compared to correctly specified Cox regression models with interaction terms, misspecified models without interaction terms resulted in up to 8.95 fold bias in estimated …

Secondary Flow Of Liquid-Liquid Two-Phase Fluids In A Pipe Bend, M. Ayala, P. Santos, G. Hamester, O. Ayala

Engineering Technology Faculty Publications

A simulated study of oil and water in 90 degree bend was carried on COMSOL 5.1 to characterize flow pattern and analyze the secondary flow. The Euler-Euler k-e Reynolds Averaged Navier-Stokes model was used to represent the fluid motion. Changes in the Reynolds number, curvature ratio and direction of gravity were made to evaluate the effects in the intensity of the secondary flow. In the end, it was possible to see that the bend direction does not affect the formation of secondary flow for Reynolds above 100,000. It appears that the fluid behavior on the pipe bend is strongly related …

Two-Arm Randomized Pilot Intervention Trial To Decrease Sitting Time And Increase Sit-To-Stand Transitions In Working And Non-Working Older Adults., Jacqueline Kerr, Michelle Takemoto, Khalisa Bolling, Andrew Atkin, Jordan A. Carlson, Dori Rosenberg, Katie Crist, Suneeta Godbole, Brittany Lewars, Claudia Pena, Gina Merchant

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Excessive sitting has been linked to poor health. It is unknown whether reducing total sitting time or increasing brief sit-to-stand transitions is more beneficial. We conducted a randomized pilot study to assess whether it is feasible for working and non-working older adults to reduce these two different behavioral targets.

METHODS: Thirty adults (15 workers and 15 non-workers) age 50-70 years were randomized to one of two conditions (a 2-hour reduction in daily sitting or accumulating 30 additional brief sit-to-stand transitions per day). Sitting time, standing time, sit-to-stand transitions and stepping were assessed by a thigh worn inclinometer (activPAL). Participants …

Vague Neuroglycopenic Complaints Camouflage Diagnosis Of Adolescent Insulinoma: A Case Report., Kelsee Halpin, Ryan Mcdonough, Patria Alba, Jared Halpin, Vivekanand Singh, Yun Yan

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Insulinoma is a rare diagnosis in the general population with estimates of 1 in 250,000 people per year. Reports of these pancreatic islet cell tumors are even more unusual in children and adolescents. Chronic hypoglycemia due to an insulinoma often presents with neuroglycopenic symptoms that can easily be overlooked, especially in adolescents where nonspecific complaints are common. This may result in delayed diagnosis with prolonged periods of untreated hypoglycemia and associated complications. The rarity of pediatric insulinoma, vagueness of presenting symptoms, and challenge of tumor localization make insulinoma a true diagnostic quandary for clinicians.

Ketogenic Diet Decreases Emergency Room Visits And Hospitalizations Related To Epilepsy., Husam R. Kayyali, Anastasia Luniova, Ahmed Abdelmoity

Manuscripts, Articles, Book Chapters and Other Papers

Background. Approximately, one-third of patients with epilepsy are refractory to pharmacological treatment which mandates extensive medical care and imposes significant economic burden on patients and their societies. This study intends to assess the impact of the treatment with ketogenic diet (KD) on reducing seizure-related emergency room visits and hospitalizations in children with refractory epilepsy. Methods. This is a retrospective review of children treated with the KD in one tertiary center. We compared a 12 months' period prior to KD with 12 months after the diet was started in regard to the number of emergency department (ED) visits, hospitalizations, …

Whole-Genome Sequencing And Disability In The Nicu: Exploring Practical And Ethical Challenges., Michael J. Deem

Manuscripts, Articles, Book Chapters and Other Papers

Clinical whole-genome sequencing (WGS) promises to deliver faster diagnoses and lead to better management of care in the NICU. However,several disability rights advocates have expressed concern that clinical use of genetic technologies may reinforce and perpetuate stigmatization of and discrimination against disabled persons in medical and social contexts. There is growing need, then, for clinicians and bioethicists to consider how the clinical use of WGS in the newborn period might exacerbate such harms to persons with disabilities. This article explores ways to extend these concerns to clinical WGS in neonatal care. By considering these perspectives during the early phases of …

The Quintessential Law Library And Librarian In A Digital Era, Femi Cadmus

Faculty Scholarship

Libraries, like most institutions and industries today, are faced with disruptive technologies that challenge their relevancy in a digital era. As a result, erstwhile notions and nostalgia associated with the quintessential library and librarian are changing rapidly. This is a compelling era to reimagine the library, retaining essential traditions alongside the new technologies, which facilitate the preservation, discoverability, accessibility, and delivery of information. It is also an opportunity for libraries to respond creatively and innovatively to change. The quintessential law library and librarian cannot only survive but can also thrive in the digital era by continuing to demonstrate value through …

Neighborhoods By Assessment: An Analysis Of Non-Ad Valorem Financing In California, Mathew D. Mccubbins, Ellen C. Seljan

Faculty Scholarship

Non-ad valorem assessments on property are a fiscal innovation born from financial stress. Unable to raise property taxes due to limitations, many localities have turned to these charges as an alternative method to fund local services. In this paper, we seek to explain differential levels of non-ad valorem assessment financing through the analysis of property tax records of a large and diverse set of single family homes in California. We theorize that assessments, as opposed to other forms of taxation, will be used when residents hold anti-redistributive preferences. We show that assessment financing is most common in cities with high …

The Supreme Court As A Filter Between International Law And American Constitutionalism, Curtis A. Bradley

Faculty Scholarship

As part of a symposium on Justice Stephen Breyer’s book, “The Court and the World,” this essay describes and defends the Supreme Court’s role as a filter between international law and the American constitutional system. In this role, the Court ensures that when international law passes into the U.S. legal system, it does so in a manner consistent with domestic constitutional values. This filtering role is appropriate, the Essay explains, in light of the different processes used to generate international law and domestic law and the different functions served by these bodies of law. The Essay provides examples of this …

Does Medical Malpractice Law Improve Health Care Quality?, Michael D. Frakes, Anupam B. Jena

Faculty Scholarship

Despite the fundamental role of deterrence in justifying a system of medical malpractice law, surprisingly little evidence has been put forth to date bearing on the relationship between medical liability forces on the one hand and medical errors and health care quality on the other. In this paper, we estimate this relationship using clinically validated measures of health care treatment quality constructed using data from the 1979 to 2005 National Hospital Discharge Surveys and the 1987 to 2008 Behavioral Risk Factor Surveillance System records. Drawing upon traditional, remedy-centric tort reforms — e.g., damage caps — we estimate that the current …

Competing For Refugees: A Market-Based Solution To A Humanitarian Crisis, Joseph Blocher, Mitu Gulati

Faculty Scholarship

The current refugee crisis demands novel legal solutions, and new ways of summoning the political will to implement them. As a matter of national incentives, the goal must be to design mechanisms that discourage countries of origin from creating refugees, and encourage host countries to welcome them. One way to achieve this would be to recognize that persecuted refugee groups have a financial claim against their countries of origin, and that this claim can be traded to host nations in exchange for acceptance. Modifications to the international apparatus would be necessary, but the basic legal elements of this proposal already …

Applying Basic Gamification Techniques To It Compliance Training: Evidence From The Lab And Field, Ryan J. Baxter, D. Kip Holderness, David A. Wood

Faculty Publications

Companies depend on strong internal controls to protect the integrity of accounting information systems. IT security and data privacy training are critical controls to safeguarding company information. However, employees often dislike the training, which can cause a lack of attention to and poor understanding of training concepts, leading to less effective internal controls. To improve the training experience, companies are implementing principles of games into employee training modules; a practice known as gamification. Using a laboratory experiment of data privacy training and a field study involving a publicly-traded bank’s rollout of IT security training, we test whether a training environment …

Do Managers Really Guide Through The Fog? On The Challenges In Assessing The Causes Of Voluntary Disclosure, Travis Dyer, Mark Lang, Lorien Stice-Lawrence

Faculty Publications

Guay e tal. (2016) document that firms with longer and more complex 10-Ks provide  relatively more voluntary disclosure, which they interpret as evidence that managers use voluntary disclosure to mitigate negative effects of complex mandatory disclosure. We review the results of Guay et al. and focus on two main challenges to inferring causality: (1) the coincidence of upward over-time trends in annual report length, complexity, and voluntary disclosure, and (2) the potential for omitted correlated variables, such as changes in firm economics, to drive changes in 10-K textual characteristics and voluntary disclosure. While the results in Guay et al. are …

Measurement And Outcomes Of Identity Communication In Virtual Teams, Susan A. Brown, Sherry M. B. Thatcher, David W. Wilson

Faculty Publications

Virtual teams play an important role in the modern economy, and many organizations struggle to overcome the weaknesses inherent in technologymediated work. Drawing from a strong empirical foundation for identity-related outcomes in nonmediated settings, we propose that perceived virtual identity communication accuracy positively impacts virtual team trust and performance. We further propose that capabilities of the communication medium can either support or hinder perceived virtual identity communication accuracy. In three studies with a cumulative sample of N=410, this research-in-progress paper reports on the first phase of a two-phase study. We develop survey scales for a medium’s identity communication capabilities and …

Serious Games: An Evaluation Framework And Case Study, David W. Wilson, Jeff Jenkins, Nathan Twyman, Matthew Jensen, Joe Valacich, Norah Dunbar, Scott Wilson, Claude Miller, Bradley Adame, Yu-Hao Lee, Judee Burgoon, Jay F. Nunamaker

Faculty Publications

Serious games show promise as an effective training method, but such games are complex and few guidelines exist for their effective evaluation. We draw on the design science literature to develop a serious game evaluation framework that emphasizes grounding evaluation in each of four key areas— theoretical, technical, empirical, and external. We further recommend that serious game developers assume an iterative, adaptive approach to grounding an evaluation effort in these four areas, emphasizing some areas more than others at different stages of the development cycle. We illustrate our framework using a case study of a large-scale serious game development project. …

Application Of Expectancy Violations Theory To Communication With And Judgments About Embodied Agents During A Decision-Making Task, Judee K. Burgoon, Joseph Bonito, Paul Benjamin Lowry, Sean Humphreys, Gregory D. Moody, James Gaskin, Justin Giboney

Faculty Publications

Because users treat embodied agents (EAs) as social actors, users hold expectations about human-to-EA communication (HtEAC) similar to those in human-to-human communication. This study extends Expectancy Violations Theory (EVT) to examine how different forms of interfaces that confirm or violate user expectations affect the communication process, social judgments, ability to influence, and accuracy of recall associated with HtEAC. Positive violations of expectancy are acts or characteristics of the EA that are unexpected but evaluated favorably by the human partner. Results suggest that when the EA deviates from expectations, effects on the HtEAC process and related outcomes can be more pronounced. …

Time-Chunking And Hyper-Refocusing In A Digitally-Enabled Workplace: Six Forms Of Knowledge Workers, James E. Gaskin, Tanner Skousen

Faculty Publications

Until the turn of the millennium, switching tasks required moving locations or reconfiguring physical workspaces. However, contemporary digital tools and workspaces allow knowledge workers to perform an increasingly diverse set of tasks, with an increasingly extending arm of influence, all from the same physical location without any physical reconfigurations or traversing of physical space. Along with this increased ambidexterity comes an increase in the quantity and frequency of demands on the time of knowledge workers. This digitalization of work now tethers their ability to perform largely to their ability to intensely focus in small chunks, and then “hyperjump” that focus …

Integrating Facial Cues Of Threat Into Security Warnings–An Fmri And Field Study, David Eargle, Dennis Galletta, C. Brock Kirwan, Anthony Vance, Jeffrey L. Jenkins

Faculty Publications

Security risks often occur because insiders fail to react appropriately to security warnings, due to inattention to the warnings. This study extends security warning design research that has investigated the impact of different designs, including different symbols of threat such as yellow triangles and exclamation marks.

This work uses media naturalness theory in an attempt to boost user engagement with security warnings. We integrated validated images of facial expressions depicting fear and disgust, which signaled an environmental threat, into a browser security warning. An fMRI study (N=23) revealed activity located in the right amygdala to be differentially associated among warnings …

Real-Time Hand Tremor Detection Via Mouse Cursor Movements For Improved Human-Computer Interactions: An Exploratory Study, Parker A. Williams, Jeffrey L. Jenkins, Joseph S. Valacich

Faculty Publications

Millions of people experience hand-tremors—rhythmic oscillation of the fingers, hands, or arm that cause shaking in the hand. People who experience hand tremors often experience difficulty in human computer interactions. For example, when browsing a website, people with hand tremors may have difficulty navigating or clicking on links in the website. With sever hand tremors, effective computing is difficult without assistance. Past research has developed interventions that can be automatically deployed by a website to make it more accessible to people with hand tremors. We build on this research by creating a methodology to unobtrusively detect hand tremors, allowing these …

Phonetic Shift /Ɔr/ Phonemic Change? American English Mergers Over 40 Years, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

In this paper we analyze the vowel formants of a speaker over four decades to show phonemic change through time. Other real-time studies (Harrington, Palethorpe & Watson 2000; Harrington & Reubold 2015) have found that the vowel spaces of UK English speakers shift over the lifetime, likely as a consequence of interaction with speakers of other dialects or social classes. We focus on an understudied variety of English, spoken in the western United States, to investigate a pair of phonological mergers, the cord-card merger and the hoarse-horse merger.

The cord-card merger is a result of a historical three-way contrast of …
