The inorganic fraction of fine particles affects numerous physicochemical processes in the atmosphere. However, there is large uncertainty in its burden and composition due to limited global measurements. Here, we present observations from eleven different aircraft campaigns from around the globe and investigate how aerosol pH and ammonium balance change from polluted to remote regions, such as over the oceans. Both parameters show increasing acidity with remoteness, at all altitudes, with pH decreasing from about 3 to about −1 and ammonium balance decreasing from almost 1 to nearly 0. We compare these observations against nine widely used chemical transport models …

Cycling Phosphorus And Nitrogen Through Cropping Systems In An Intensive Dairy Production Region, April B. Leytem, Paula Williams, Shan Zuidema, Audrey Martinez, Yen Leng Chong, Alyssa Vincent, Aaron Vincent, Daniel Cronan, Andrew Kliskey, J. D. Wulfhorst, Lilian Alessa, David Bjorneberg

Faculty Publications

As pressure on the dairy industry to reduce its environmental impact increases, efficient recycling of manure nutrients through local cropping systems becomes crucial. The aim of this study was to calculate annual nitrogen (N) and phosphorus (P) budgets in six counties located in the Magic Valley, Idaho and estimate what distance manure would need to be transported to be in balance with crop nutrient demand given current dairy cattle populations and cropping systems. Our analysis suggests that crop N needs will not be met solely by manure, and synthetic fertilizer will need to be applied. However, to balance P with …

Covid-19: A Syndemic Requiring An Integrated Approach For Marginalized Populations, Rosemary M. Caron, Amanda Rodrigues Amorim Adegboye

Faculty Publications

The novel coronavirus, SARS-CoV-2, responsible for the COVID-19 pandemic, has challenged healthcare systems globally. The health inequities experienced by immigrants, refugees, and racial/ethnic minorities have been aggravated during the COVID-19 pandemic. The socioeconomic, political, and demographic profile of these vulnerable populations places them at increased risk of contracting COVID-19 and experiencing significant morbidity and mortality. Thus, the burden of the COVID-19 pandemic is disproportionally higher among these at-risk groups. The purpose of this perspective is to: (1) highlight the interactions among the social determinants of health (SDoH) and their bi-directional relationship with the COVID-19 pandemic which results in the current …

Model For Quantifying The Quality Of Secure Service, Paul M. Simon, Scott R. Graham, Christopher Talbot, Micah J. Hayden

Faculty Publications

Although not common today, communications networks could adjust security postures based on changing mission security requirements, environmental conditions, or adversarial capability, through the coordinated use of multiple channels. This will require the ability to measure the security of communications networks in a meaningful way. To address this need, in this paper, we introduce the Quality of Secure Service (QoSS) model, a methodology to evaluate how well a system meets its security requirements. This construct enables a repeatable and quantifiable measure of security in a single- or multi-channel network under static configurations. In this approach, the quantification of security is based …

Data collected from research networks present opportunities to test theories and develop models about factors responsible for the long-term persistence and vulnerability of soil organic matter (SOM). Synthesizing datasets collected by different research networks presents opportunities to expand the ecological gradients and scientific breadth of information available for inquiry. Synthesizing these data is challenging, especially considering the legacy of soil data that have already been collected and an expansion of new network science initiatives. To facilitate this effort, here we present the SOils DAta Harmonization database (SoDaH; https://lter.github.io/som-website, last access: 22 December 2020), a flexible database designed to harmonize diverse …

Delivering Bad News: Crisis Communication Methods In Academic Libraries, Brittany O'Neill, Rebecca Kelley

Faculty Publications

This exploratory study analyzed the specific crisis communication methods of academic libraries. A survey was sent to library staff at Association of Research Libraries-member colleges and universities to describe if, who, when, and how they communicated bad news to their stakeholders for major, minor, and emerging crises. The findings show that respondents used multiple communication strategies, which varied based on the crisis. The data show that libraries communicated journal and database cancellations and health and safety emergencies more slowly than access issues and were more likely not to communicate those crises at all. Respondents also more frequently chose to communicate …

On The Cusp Of The Next Medical Malpractice Insurance Crisis, Philip G. Peters Jr.

Faculty Publications

Medical malpractice claims are dwindling. Total payouts are far lower than during the 2002 crisis. Yet, insurance industry profits have been sinking for a decade and are nearly in the red. After a dozen years with a “soft” insurance market, we are now on the cusp of yet another malpractice insurance crisis.

How can profits be in peril if claims have dwindled and payouts are historically low?
Answering that question requires an understanding of the insurance cycle. The cycle periodically transforms gradual increases in costs and gradual decreases in revenue into explosive increases in premiums.

The industry’s financial statistics today …

Performance Measurements Within Asynchronous Task-Based Runtime Systems: A Double White Dwarf Merger As An Application, Patrick Diehl, Dominic Marcello, Parsa Amini, Hartmut Kaiser, Sagiv Shiber, Geoffrey C. Clayton, Juhan Frank, Gregor Dais, Dirk Pfluger, David Eder, Alice Koniges, Kevin Huck

Faculty Publications

Analyzing performance within asynchronous many-task-based runtime systems is challenging because millions of tasks are launched concurrently. Especially for long-term runs, the amount of data collected becomes overwhelming. We study HPX and its performance-counter framework and autonomic performance environment for Exascale to collect performance data and energy consumption. We added HPX application-specific performance counters to the Octo-Tiger full 3-D adaptive multigrid code astrophysics application. This enables the combined visualization of physical and performance data to highlight bottlenecks with respect to different solvers. We examine the overhead introduced by these measurements, which is around 1%, with respect to the overall application runtime. …

Citations Versus Expert Opinions: Citation Analysis Of Featured Reviews Of The American Mathematical Society, Lawrence Smolinsky, Daniel S. Sage, Aaron J. Lercher, Aaron Cao

Faculty Publications

Peer review and citation metrics are two means of gauging the value of scientific research, but the lack of publicly available peer review data makes the comparison of these methods difficult. Mathematics can serve as a useful laboratory for considering these questions because as an exact science, there is a narrow range of reasons for citations. In mathematics, virtually all published articles are post-publication reviewed by mathematicians in Mathematical Reviews (MathSciNet) and so the data set was essentially the Web of Science mathematics publications from 1993 to 2004. For a decade, especially important articles were singled out in Mathematical Reviews …

Conceptus Metabolomic Profiling Reveals Stage-Specific Phenotypes Leading Up To Pregnancy Recognition In Cattle†, Constantine A. Simintiras, José M. Sánchez, Michael Mcdonald, Elena O'Callaghan, Ahmed A. Aburima, Patrick Lonergan

Faculty Publications

Reproductive efficiency in livestock is a major driver of sustainable food production. The poorly understood process of ruminant conceptus elongation (a) prerequisites maternal pregnancy recognition, (b) is essential to successful pregnancy establishment, and (c) coincides with a period of significant conceptus mortality. Conceptuses at five key developmental stages between Days 8-16 were recovered and cultured in vitro for 6 h prior to conditioned media analysis by untargeted ultrahigh-performance liquid chromatography tandem mass spectroscopy. This global temporal biochemical interrogation of the ex situ bovine conceptus unearths two antithetical stage-specific metabolic phenotypes during tubular (metabolically retentive) vs. filamentous (secretory) development. Moreover, the …

Circadian Rhythms In Legumes: What Do We Know And What Else Should We Explore?, Hazel Marie Kugan, Nur Ardiyana Rejab, Nurul Amylia Sahruzaini, Jennifer Ann Harikrishna, Niranjan Baisakh, Acga Cheng

Faculty Publications

The natural timing devices of organisms, commonly known as biological clocks, are composed of specific complex folding molecules that interact to regulate the circadian rhythms. Circadian rhythms, the changes or processes that follow a 24‐h light–dark cycle, while endogenously programmed, are also influenced by environmental factors, especially in sessile organisms such as plants, which can impact ecosystems and crop productivity. Current knowledge of plant clocks emanates primarily from research on Arabidopsis, which identified the main components of the circadian gene regulation network. Nonetheless, there remain critical knowledge gaps related to the molecular components of circadian rhythms in important crop groups, …

Roboethics In Covid-19: A Case Study In Dentistry, Wendy C. Birmingham, Yaser Maddahi, Maryam Kalvandi, Sofya Langman, Nicole Capicotto, Kourosh Zareinia

Faculty Publications

The COVID-19 pandemic has caused dramatic effects on the healthcare system, businesses, and education. In many countries, businesses were shut down, universities and schools had to cancel in-person classes, and many workers had to work remotely and socially distance in order to prevent the spread of the virus. These measures opened the door for technologies such as robotics and artificial intelligence to play an important role in minimizing the negative effects of such closures. There have been many efforts in the design and development of robotic systems for applications such as disinfection and eldercare. Healthcare education has seen a lot …

Relationship Among Combat Experience, Veteran Pathology, And Pathology Of Veterans’ Intimate Partners: Factors Predicting The Pathology Of Veterans And Their Intimate Partners, Edwin A. Brennan, Nancy Carbonell, Jimmy Kijai, Dennis Waite

Faculty Publications

Introduction: Military members and their families have been part of the Global War on Terrorism since the September 11, 2001, terrorist attacks on the United States. As a result, higher levels of pathology — such as posttraumatic stress disorder, generalized anxiety disorder, and depression — are being seen. No known studies have addressed the concept of resonating pathology between combat Veterans and their intimate partners. Resonating pathology, for the purpose of this study, is when the combat Veteran and their intimate partner demonstrate the same pathology at similar levels. Methods: Veterans and their intimate partners from across the United States …

Building Resilience In Children And Youth, Alina M. Baltazar, Gary L. Hopkins

Faculty Publications

No one is immune to life’s challenges. The COVID-19 pandemic has made that clear to any doubters and raised the issue of “resilience” into the top tiers of popular news topics. Resilience is the capacity to maintain competent functioning in the face of major life stressors. Since social problems are not going away, how do we create a culture in which children can do well in spite of adverse life experiences? Resilience is not a personality trait that someone is born with, but rather a capacity that develops over time. Think of resilience as a balance with negative life experiences …

Restoring Trust In Truth-Seekers: Effects Of Op/Eds Defending Journalism And Justice, Raymond J. Pingree, Martina Santia, Kirill Bryanov, Brian K. Watson

Faculty Publications

A healthy democracy requires trust that people can be impartial in important truth-seeking institutions including journalism, justice, and science. Recently some U.S. elites have adopted alarmingly extreme rhetoric against truth-seekers, denouncing mainstream journalism as fake news, criminal investigations as partisan witch-hunts, climate science as a hoax, and career civil servants as a deep state conspiracy. In response, some news organizations have taken the unusual step of publishing op/eds defending these institutions. Two experiments tested effects of such op/eds. In study 1, participants spent twelve days using a purpose-built news portal containing real, timely news with random assignment to the availability …

Real-Time Motion Tracking Of Cognitive Baxter Robot Based On Differential Inverse Kinematics, Shaobo Li, Xingxing Zhang, Jing Yang, Qiang Bai, Jianjun Hu, Qisong Song, Zhiang Li

Faculty Publications

The tracking motion of the robot is realized based on a specific robot or relying on an expensive movement acquisition system. It has the problems of complex control procedures, lack of real-time performance, and difficulty in achieving secondary development. We propose a robot real-time tracking control method based on the control principle of differential inverse kinematics, which fuses the position and joint angle information of the robot’s actuators to realize the real-time estimation of the user’s movement during the tracking process. The motion coordinates of each joint of the robot are calculated and the coordinate conversion between man and machine …

Teaching Leadership In American Law Schools: Why The Pushback?, Martin H. Brinkley

Faculty Publications

In September 2020, I participated in a panel discussion with several other deans at Baylor Law School’s 2020: Vision for Leadership Conference. The subject was “Leadership Programming in Law Schools.”

My assignment was to account for why teaching leadership might meet with resistance from inside law schools, despite widespread agreement that lawyer-leaders have always been and are always likely be critical to the survival of American democracy, as well as our fellow citizens’ hopes of living meaningful, satisfying lives.

This essay endeavors to memorialize and expand on the views I expressed on the panel.

Defect Detection In Atomic Resolution Transmission Electron Microscopy Images Using Machine Learning, Philip Cho, Aihua W. Wood, Krishnamurthy Mahalingam, Kurt Eyink

Faculty Publications

Point defects play a fundamental role in the discovery of new materials due to their strong influence on material properties and behavior. At present, imaging techniques based on transmission electron microscopy (TEM) are widely employed for characterizing point defects in materials. However, current methods for defect detection predominantly involve visual inspection of TEM images, which is laborious and poses difficulties in materials where defect related contrast is weak or ambiguous. Recent efforts to develop machine learning methods for the detection of point defects in TEM images have focused on supervised methods that require labeled training data that is generated via …

An Evaluation Framework For Allied Legal Professional Programs: Assessing Improvements In Access To Justice, Andrea L. Miller, Paula Hannaford-Agor, Kathryn Genthon

Faculty Publications

The American legal system has a civil access-to-justice gap, wherein many people with civil legal issues are unable to obtain legal assistance. People with civil legal issues who cannot afford an attorney frequently must proceed through the legal system on their own. As the number of Self-Represented Litigants (SRLs) grows, several jurisdictions have investigated the creation of an additional tier of legal service providers, who can give limited legal assistance at a lower price than attorneys. For the purposes of this report, we will refer to these service providers as Allied Legal Professionals (ALPs). ALP programs can involve a wide …

Reconsidering Section 1983'S Nonabrogation Of Sovereign Immunity, Katherine Mims Crocker

Faculty Publications

Motivated by civil unrest and the police conduct that prompted it, Americans have embarked on a major reexamination of how constitutional enforcement works. One important component is 42 U.S.C. § 1983, which allows civil suits against any "person" who violates federal rights. The U.S. Supreme Court has long held that "person" excludes states because Section 1983 flunks a condition of crystal clarity.

This Article reconsiders that conclusion--in legalese, Section 1983's nonabrogation of sovereign immunity--along multiple dimensions. Beginning with a negative critique, this Article argues that because the Court invented the crystal-clarity standard so long after Section 1983's enactment, the caselaw …

A quartet of performers tested the Global Hyperorgan’s capacities for telematic musicking through a series of pieces. The concept of modularity is useful when considering the artistic challenges and possibilities of the Global Hyperorgan. We observe …

Potential Roles Of Endoplasmic Reticulum Stress And Cellular Proteins Implicated In Diabesity, Sagir Mustapha, Mustapha Mohammed, Ahmad Khusairi Azemi, Ismaeel Yunusa, Aishatu Shehu, Lukman Mustapha, Yusuf Wada, Mubarak Hussaini Ahmad, Wan Amir Wan Ahmad, Aida Hanum Ghulam Rasool, Siti Safiah Mokhtar

Faculty Publications

The role of the endoplasmic reticulum (ER) has evolved from protein synthesis, processing, and other secretory pathways to forming a foundation for lipid biosynthesis and other metabolic functions. Maintaining ER homeostasis is essential for normal cellular function and survival. An imbalance in the ER implied stressful conditions such as metabolic distress, which activates a protective process called unfolded protein response (UPR). This response is activated through some canonical branches of ER stress, i.e., the protein kinase RNA-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1α (IRE1α), and activating transcription factor 6 (ATF6). Therefore, chronic hyperglycemia, hyperinsulinemia, increased proinflammatory …

Investors’ Reactions To Csr News In Family Versus Nonfamily Firms: A Study On Signal (In)Credibility, Naciye Sekerci, Jamil Jaballah, Marc Van Essen, Nadine Kammerlander

Faculty Publications

We study family firm status as an important condition in signaling theory; specifically, we propose that the market reacts more positively to positive, and more negatively to negative, CSR news (i.e., signals) from family firms than to similar news from nonfamily firms. Moreover, we propose that during recessions, the direction of these relationships reverses. Based on an event study of 1247 positive and negative changes in the CSR ratings for all firms listed on the French SFB120 stock market index (2003-2013), we find support for our hypotheses. Moreover, a post hoc analysis reveals that the relationships are contingent on whether …
