Wage Differences Matter: An Experiment Of Social Comparison And Effort Provision When Wages Increase Or Decrease, Jose A. Rojas-Fallas, J. Forrest Williams

Economics Faculty Publications and Presentations

Wage rates, efficiency wages, and gift exchange in a labor market are all crucial aspects in regard to designing contracts to ensure high effort from workers. We extend this literature by discussing the relationship between known differences in wages (social comparison) and workers’ effort provision. We conduct an experiment in which subjects perform effort tasks for piece-rates. All subjects are paid the same wage rate in the first half of the experiment, but in the second half are paid different wage rates; the primary variable we study is the information about others’ wage rates given to a subset of subjects. …

The Vimentin Rod Domain Blocks P-Selectin-P-Selectin Glycoprotein Ligand 1 Interactions To Attenuate Leukocyte Adhesion To Inflamed Endothelium, Fong Wilson Lam, Cameron August Brown, Christian Valladolid, Dabel Cynthia Emebo, Timothy Gerald Palzkill, Miguel Angel Cruz

Faculty, Staff and Students Publications

Acute inflammation begins with leukocyte P-selectin glycoprotein ligand-1 (PSGL-1) binding to P-selectin on inflamed endothelium and platelets. In pathologic conditions, this process may contribute to secondary organ damage, like sepsis-induced liver injury. Therefore, developing novel therapies to attenuate inflammation may be beneficial. We previously reported that recombinant human vimentin (rhVim) binds P-selectin to block leukocyte adhesion to endothelium and platelets. In this study, we used SPOT-peptide arrays to identify the rod domain as the active region within rhVim that interacts with P-selectin. Indeed, recombinant human rod domain of vimentin (rhRod) binds to P-selectin with high affinity, with in silico modeling …

Extracellular Mitochondria Released From Traumatized Brains Induced Platelet Procoagulant Activity, Zilong Zhao, Yuan Zhou, Tristan Hilton, Fanjian Li, Cha Han, Li Liu, Hengjie Yuan, Ying Li, Xin Xu, Xiaoping Wu, Fangyi Zhang, Perumal Thiagarajan, Andrew Cap, Fu-Dong Shi, Jianning Zhang, Jing-Fei Dong

Faculty, Staff and Students Publications

Coagulopathy often develops soon after acute traumatic brain injury and its cause remains poorly understood. We have shown that injured brains release cellular microvesicles that disrupt the endothelial barrier and induce consumptive coagulopathy. Morphologically intact extracellular mitochondria accounted for 55.2% of these microvesicles, leading to the hypothesis that these extracellular mitochondria are metabolically active and serve as a source of oxidative stress that activates platelets and renders them procoagulant. In testing this hypothesis experimentally, we found that the extracellular mitochondria purified from brain trauma mice and those released from brains subjected to freeze-thaw injury remained metabolically active and produced reactive …

Reduced Bacterial Burden Of The Skin Surrounding The Shoulder Joint Following Topical Protocatechuic Acid Application: Results Of A Pilot Study, Omid Jalali, Molly Best, Alison Wong, Brett Schaeffer, Brendon Bauer, Lanny Johnson

Faculty, Staff and Students Publications

BACKGROUND: Reducing the rising health-care burden associated with shoulder surgical site infection (SSI) is of paramount importance. The purpose of this study was to investigate the antimicrobial efficacy of protocatechuic acid (PCA) as a topical reagent for surgical skin antisepsis surrounding the shoulder joint.

METHODS: This was a 2-phase skin-disinfection trial involving the human shoulder. The shoulders of healthy volunteers were randomized to topical treatment with PCA (a 10% concentration of PCA in Phase I [11 subjects] and a 17% concentration in Phase II [12 subjects]), with a control of isopropyl alcohol (IPA) applied to the contralateral shoulder. Mechanical scraping …

Dustbowl Waters: Doctrinal And Legislative Solutions To Save The Ogallala Aquifer Before Both Time And Water Run Out, Warigia M. Bowman

Articles, Chapters in Books and Other Contributions to Scholarly Works

Eighty-three years after the Dust Bowl, residents of America’s High Plains face a dire threat: their primary aquifer faces depletion, and entire sections of the country are set to run out of groundwater by the end of the century or sooner. The Ogallala Aquifer provides a significant amount of America’s agricultural irrigation water and is a primary source of drinking water for Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This Article argues that policymakers should slow the Aquifer’s depletion rate by implementing changes to irrigation technology, crop choice, consumer behavior, legal doctrine, and legislation. This Article …

Navigating Technology Competence In Transactional Practice, Lori D. Johnson

Scholarly Works

In 2012, the American Bar Association House of Delegates, based on the work of the ABA Commission on Ethics 20/20, amended the Model Rules of Professional Conduct (Model Rules) to include a new requirement concerning lawyer competence. The obligation, enacted as Comment 8 to existing Model Rule 1.1 (outlining a lawyer's requisite competence) (Rule 1.1), requires lawyers "keep abreast of changes in the law and its practice, including the benefits and risks associated with relevant technology." To date, Comment 8 to Rule 1.1 (Comment 8 or the Comment) has been adopted in thirty-eight states, and has begun generating scholarship and …

Training Law Students To Maintain Civility In Their Law Practices As A Way To Improve Public Discourse, Nancy B. Rapoport

Scholarly Works

Our current social discourse is broken. Not only have we resorted to name-calling instead of reasoned discussion, but we have also resorted to the fundamental attribution error: we attribute bad motives to people with whose positions we disagree rather than starting with the presumption that, perhaps, buried deep within their positions could be a grain of truth. As Yoni Appelbaum observed in a recent article in The Atlantic, "Recent research by political scientists at Vanderbilt University and other institutions has found both Republicans and Democrats distressingly willing to dehumanize members of the opposite party."' We need to find a …

#Metoo Backlash Or Simply Common Sense?: It's Complicated, Ann C. Mcginley

Scholarly Works

This Essay focuses on the skittishness that men express about being accused of sexual harassment. Part II explains the prevalence of sexual harassment and the response to this problem, giving both empirical and anecdotal evidence of male professionals' refusals to spend time with female subordinates. Part III discusses the already-present inequalities in the legal profession, particularly in law firms and raises concerns about how lack of mentoring and sponsorship of women by male supervisors could create an even greater disparity. Part IV analyzes the disparate legal, business, and cultural definitions of sexual harassment, and given the disparities in understandings, raises …

Cruzan And Surrogate Decision-Making, David Orentlicher

Scholarly Works

When the U.S. Supreme Court issued its landmark “right to die” decision in Cruzan v. Director, Missouri Department of Health thirty years ago, the dissenting Justices and many observers criticized the Court for rejecting a right of Nancy Cruzan’s parents to refuse medical care on her behalf. Ms. Cruzan had not written a living will or a durable power of attorney, nor did it appear that she had left clear oral instructions about her wishes. But she did have loving parents who were dedicated to doing what was best for her. Nevertheless, according to the Cruzan Court, “If the State …

Invisible Prisons, M. Eve Hanan

Scholarly Works

Modern punishment theory is based on an inadequate conceptualization of the severity of incarceration. While the severity of a prison sentence is measured solely in terms of the length of time, the actual experience of imprisonment is often more punishing and more destructive than a simple loss of liberty. Yet, lawmakers and judges evince a surprising lack of institutional interest in understanding the experience of imprisonment and applying this knowledge to sentencing. This lack of official attention to how prison is experienced by incarcerated people is one of the drivers of mass incarceration.

This Article is the first scholarly work …

Targeting Factors And Conflict Of Laws On The Internet, Marketa Trimble

Scholarly Works

Courts have employed the concept of "targeting" to limit the reach of personal jurisdiction and applicable law on the Internet. To determine whether a defendant has targeted a particular country or state-and whether the defendant should be subject to the jurisdiction of and law in that country or state-courts consider various factors, such as the language, the top-level domain, and the currency used by the defendant on the Internet. However, developments in Internet technology and increasing Internet actor and user sophistication put the significance of the factors into question. In the absence of a defendant's express limitation on the territorial …

Building Worker Collective Action Through Technology, Ruben J. Garcia

Scholarly Works

The COVID-19 pandemic has exacerbated the inequality between workers and their employers, and decreased worker power over their terms and conditions of employment. At the same time, the workers are more dispersed than ever, with more employers disestablishing the traditional office in favor of a hybrid model that further atomizes workers and makes collective action harder. At the same time, the ability for workers to organize themselves on social media and on company e-mail systems has been limited by recent decisions of the National Labor Relations Board (NLRB), and are always subject to possible employer discovery and retaliation. New technologies …

The Debt Collection Pandemic, Pamela Foohey, Dalie Jimenez, Chris Odinet

Articles by Maurer Faculty

To curb the rapid spread of the coronavirus set to overwhelm the United States' healthcare system, in mid-March 2020, the federal government declared a national emergency. Many states followed suit by implementing shelter-at-home orders and people began social distancing across America. As of this writing, the United States' reaction to the unique and alarming threat of COVID 19 has partially succeeded in slowing the virus's spread. Saving people's lives, however, has come at a severe economic cost. Economic activity plummeted. Unemployment numbers soured to figures not seen since the Great Depression and countless other people saw their income disappear.

Do Founders Control Start-Up Firms That Go Public?, Brian Broughman, Jesse M. Fried

Articles by Maurer Faculty

Black & Gilson (1998) argue that an IPO-welcoming stock market stimulates venture deals by enabling VCs to give founders a valuable "call option on control." We study 18,000 startups to investigate the value of this option. Among firms that reach IPO, 60% of founders are no longer CEO. With little voting power, only half of the others survive three years as CEO. At initial VC financing, the probability of getting real control of a public firm for three years is 0.4%. Our results shed light on control evolution in startups, and cast doubt on the plausibility of the call-option theory …

Doing Unrepresented Status: The Social Construction And Production Of Pro Se Persons, Victor D. Quintanilla

Articles by Maurer Faculty

In this Article, I propose an understanding of the dynamic process through which society does unrepresented status that is informed by psychological and sociological research. In describing this doing of unrepresented status, I elaborate on two new concepts: the social construction of pro se status and the social production of unrepresented persons. These concepts illuminate ways in which the doing of unrepresented status is a routine, recurring feature in how court officials, lawyers, and law-trained persons perceive and interact with unrepresented persons within our civil justice system. That is, a pro se party is not something that an unrepresented person …

Exploring White Critical Consciousness Of Christian College Students At A Midwestern College, Jesse M. Brown

All-Inclusive List of Electronic Theses and Dissertations

Whiteness is pervasive and hidden on Christian college campuses. Helms (2017) defined Whiteness as the overt and subliminal socialization processes and practices, power structures, laws, privileges, and life experiences that favor the White racial group over all others” (p. 718). Whiteness can often be ignored or overlooked by White persons and predominantly White institutions. Normalizing Whiteness rather than working through Whiteness perpetuates the subliminal and overt practices found on many Christian college campuses. While the study of Whiteness in higher education is a growing field (Cabrera, 2014; Cabrera et al., 2016; Cabrera et al., 2017), limited research has linked Whiteness …

Teaching Jihad: Developing Religious Literacy Through Graphic Novels, Melanie C. Brooks, Kelly Deits Cutler, Fida Sanjakdar, Daniel D. Liou

Curriculum and Instruction Faculty Publications and Presentations

This study examined the representations of jihad in graphic novels to ascertain how its depictions may inform the development of religious literacy in secondary classrooms. Hegemonic constructions of jihad in theWest are commonly reduced to false binaries that shape non-Muslims’ extant beliefs and perceptions of Islam and Muslims. This raises concerns about the ways in which societal expectations shape knowledge formation in schools. Accordingly, this critical content analysis explored the depiction of jihad in three graphic novel memoirs, an increasingly popular medium of instruction in secondary classrooms. Our analysis identified three forms of jihad conveyed through the graphic novels, specifically: …

Exploring The Impact Of Brexit On Uk’S Engineering Education Sector From The Perspective Of European Students And Staff, I. Direito, B. Williams, Shannon Chance

Conference papers

The UK higher education attracts a far higher number of international academics from all over the world, who teach and do research, than any other country in Europe, being only surpassed by Switzerland [1]. Moreover, because engineering itself is considered a global field, this sub-field of higher education also relies on international mobility more than most academic disciplines in the UK The impact of the United Kingdom European Union membership referendum of June 2016, commonly referenced as the Brexit referendum, is still unfolding and under continuing analysis. However, it is widely anticipated that it will disrupt European student and staff …

Managing The Growth Of Peer Review At The Royal Society Journals, 1865-1965, Aileen Fyfe, Flaminio Squazzoni, Didier Torny, Pierpaolo Dondio

Articles

This article examines the evolution of peer review and the modern editorial processes of scholarly journals by analyzing a novel data set derived from the Royal Society’s archives and covering 1865-1965, that is, the historical period in which refereeing (not yet known as peer review) became firmly established. Our analysis reveals how the Royal Society’s editorial processes coped with both an increasing reliance on refereeing and a growth in submissions, while maintaining collective responsibility and minimizing research waste. By engaging more of its fellows in editorial activity, the society was able to establish an equilibrium of number of submissions per …

Ambiqual: Towards A Quality Metric For Headphone Rendered Compressed Ambisonic Spatial Audio, Miroslaw Narbutt, Jan Skoglund, Andrew Allen, Michael Chinen, Dan Barry, Andrew Hines

Articles

Spatial audio is essential for creating a sense of immersion in virtual environments. Efficient encoding methods are required to deliver spatial audio over networks without compromising Quality of Service (QoS). Streaming service providers such as YouTube typically transcode content into various bit rates and need a perceptually relevant audio quality metric to monitor users’ perceived quality and spatial localization accuracy. The aim of the paper is two-fold. First, it is to investigate the effect of Opus codec compression on the quality of spatial audio as perceived by listeners using subjective listening tests. Secondly, it is to introduce AMBIQUAL, a full …
