Virtual Reality As A Pedagogical Tool To Design For Social Impact: A Design Case, Tiffany Roman, Jon Racek Dec 2018

Virtual Reality As A Pedagogical Tool To Design For Social Impact: A Design Case, Tiffany Roman, Jon Racek

Faculty Articles

Three-dimensional (3-D) virtual environments have key affordances that can improve learning, particularly when context, culture, and pedagogical aims are aligned to a given learning situation. One challenge in detailing effective uses of 3-D virtual environments in teaching and learning contexts is that the design judgments involved are not always made explicit. We argue that the transparency of design judgments, as it relates to the use of 3-D virtual environments, are critically important. This article advances scholarship of emerging technologies by detailing the design judgments of a university instructor within a Design for Social Impact cross-disciplinary course. To address learner needs …


Meditation On The Soles Of The Feet Practice Provides Some Control Of Aggression For Individuals With Alzheimer’S Disease, Nirbhay N. Singh, Giulio E. Lancioni, Oleg N. Medvedev, Rachel E. Myers Dec 2018

Meditation On The Soles Of The Feet Practice Provides Some Control Of Aggression For Individuals With Alzheimer’S Disease, Nirbhay N. Singh, Giulio E. Lancioni, Oleg N. Medvedev, Rachel E. Myers

Faculty Articles

Alzheimer’s disease is a progressive neurodegenerative condition that affects cognition, mental and physical health, and functionality of older people. As the disease progresses from the mild to moderate stage, there is a concomitant increase in several behavioral variables, chiefly agitation, anger, and aggression. Currently, there are no evidence-based treatments for these behaviors in this population. Three individuals with moderate Alzheimer’s disease were taught an informal mindfulness practice, meditation on the Soles of the Feet (SoF), as a self-management strategy within a multiple-baseline design across participants. All three were able to learn and use the SoF practice to manage their verbal …


Pasnet: Pathway-Associated Sparse Deepneural Network For Prognosis Prediction From High-Throughput Data, Jie Hao, Youngsoon Kim, Tae-Kyung Kim, Mingon Kang Dec 2018

Pasnet: Pathway-Associated Sparse Deepneural Network For Prognosis Prediction From High-Throughput Data, Jie Hao, Youngsoon Kim, Tae-Kyung Kim, Mingon Kang

Faculty Articles

Background: Predicting prognosis in patients from large-scale genomic data is a fundamentally challenging problem in genomic medicine. However, the prognosis still remains poor in many diseases. The poor prognosis maybe caused by high complexity of biological systems, where multiple biological components and their hierarchical relationships are involved. Moreover, it is challenging to develop robust computational solutions with high-dimension, low-sample size data. Results: In this study, we propose a Pathway-Associated Sparse Deep Neural Network (PASNet) that not only predicts patients’ prognoses but also describes complex biological processes regarding biological pathways for prognosis. PASNet models a multilayered, hierarchical biological system of genes …

Outcomes Of Motivational Interviewing Training With Probation And Parole Officers: Findings And Lessons Learned, Melanie M. Iarussi, Dixie F. Powers Dec 2018

Outcomes Of Motivational Interviewing Training With Probation And Parole Officers: Findings And Lessons Learned, Melanie M. Iarussi, Dixie F. Powers

Faculty Articles

Motivational Interviewing (MI) is an evidence-based approach that provides probation and parole officers with specific skills to enhance their clients' motivations to change problematic behaviors. This study investigated the outcomes of MI training with probation and parole officers whose state agency required them to complete MI training. Results show that officers' MI skills, self-efficacy, and knowledge increased following training, with some exceptions. Recommendations from implementation science literature are provided for improving MI trainings.


Autophagy And Aging: Maintaining The Proteome Through Exercise And Caloric Restriction, Kurt A. Escobar, Nathan H. Cole, Christine M. Mermier, Trisha A. Vandusseldrop Nov 2018

Autophagy And Aging: Maintaining The Proteome Through Exercise And Caloric Restriction, Kurt A. Escobar, Nathan H. Cole, Christine M. Mermier, Trisha A. Vandusseldrop

Faculty Articles

Accumulation of dysfunctional and damaged cellular proteins and organelles occursduring aging, resulting in a disruption of cellular homeostasis and progressive degen-eration and increases the risk of cell death. Moderating the accrual of these defunctcomponents is likely a key in the promotion of longevity. While exercise is knownto promote healthy aging and mitigate age‐related pathologies, the molecular under-pinnings of this phenomenon remain largely unclear. However, recent evidencessuggest that exercise modulates the proteome. Similarly, caloric restriction (CR), aknown promoter of lifespan, is understood to augment intracellular protein quality.Autophagy is an evolutionary conserved recycling pathway responsible for thedegradation, then turnover of cellular proteins …


Cteq-Tea Parton Distribution Functions With Intrinsic Charm, Marco Guzzi, Tie-Jiun Hou, Sayipjamal Dulat, Jun Gao, Joey Huston, Pavel Nadolsky, Carl Schmidt, Jan Winter, Keping Xie, C.-P. Yuan Nov 2018

Cteq-Tea Parton Distribution Functions With Intrinsic Charm, Marco Guzzi, Tie-Jiun Hou, Sayipjamal Dulat, Jun Gao, Joey Huston, Pavel Nadolsky, Carl Schmidt, Jan Winter, Keping Xie, C.-P. Yuan

Faculty Articles

We present a study in which the possibility of a (sizable) nonperturbative contribution to the charm parton distribution function (PDF) in a nucleon is investigated together with theoretical issues arising in its interpretation. The separation of the universal component of the nonperturbative charm from the rest of the radiative contributions is also discussed. We illustrate the potential impact of a nonperturbative charm PDF on LHC scattering processes. An estimate of nonperturbative charm magnitude in the CT14 and CT14HERA2 global QCD analyses at the next-to-next-to leading order (NNLO) in the QCD coupling strength is given by including the latest experimental data …


Universal Representation, Lindsay Nash Nov 2018

Universal Representation, Lindsay Nash

Faculty Articles

In an era in which there is little good news for immigrant communities and even holding the line has become an ambitious goal, one progressive project has continued to gain steam: the movement to provide universal representation for non-citizens in removal proceedings. In the immigration field, “universal representation” refers to a system of appointed counsel that provides representation to indigent non-citizens facing deportation regardless of the apparent merits of their case. This model has proven a transformative change, particularly given the absence of any recognized right to government-funded counsel. In recent years, cities and counties throughout the nation have launched …


A 4-Year Analysis Of The Incidence Of Injuries Among Crossfit-Trained Participants, Yuri Feito, Evanette K. Burrows, Loni Phillip Tabb Oct 2018

A 4-Year Analysis Of The Incidence Of Injuries Among Crossfit-Trained Participants, Yuri Feito, Evanette K. Burrows, Loni Phillip Tabb

Faculty Articles

Background: High-intensity functional training (HIFT) is a new training modality that merges high-intensity exercise with functional (multijoint) movements. Even though others exist, CrossFit training has emerged as the most common form of HIFT. Recently, several reports have linked CrossFit training to severe injuries and/or life-threatening conditions, such as rhabdomyolysis.Empirical evidence regarding the safety of this training modality is currently limited. Purpose: To examine the incidence of injuries related to CrossFit participation and to estimate the rate of injuries in a large cross-sectional convenience sample of CrossFit participants from around the world. Study Design: Descriptive epidemiology study. Methods: A total of …


Parity-Time Symmetry In Optical Microcavity Systems, Jianming Wen, Xiaoshun Jiang, Liang Jiang, Min Xiao Oct 2018

Parity-Time Symmetry In Optical Microcavity Systems, Jianming Wen, Xiaoshun Jiang, Liang Jiang, Min Xiao

Faculty Articles

Canonical quantum mechanics postulates Hermitian Hamiltonians to ensure real eigenvalues. Counterintuitively, a non-Hermitian Hamiltonian, satisfying combined parity-time (PT) symmetry, could display entirely real spectra above some phase-transition threshold. This stems from the existence of a parameter in the Hamiltonian governing characteristics features of eigenvalues and eigenfunctions. Varying this parameter causes real eigenvalues to coalesce and become complex conjugate pairs, signaling the occurrence of a nontrivial phase transition and the breakdown of PT symmetry. Such an appealing discovery has aroused extensive theoretical interest in extending canonical quantum theory by including non-Hermitian but PT-symmetric operators in the last two decades. Despite much …


Peer-Delivered Harm Reduction And Recovery Support Services: Initial Evaluation From A Hybrid Recovery Community Drop-In Center And Syringe Exchange Program, Robert D. Ashford, Brenda Curtis, Austin M. Brown Oct 2018

Peer-Delivered Harm Reduction And Recovery Support Services: Initial Evaluation From A Hybrid Recovery Community Drop-In Center And Syringe Exchange Program, Robert D. Ashford, Brenda Curtis, Austin M. Brown

Faculty Articles

Background: Recovery from substance use disorder (SUD) is often considered at odds with harm reduction strategies. More recently, harm reduction has been categorized as both a pathway to recovery and a series of services to reduce the harmful consequences of substance use. Peer recovery support services (PRSS) are effective in improving SUD outcomes, as well as improving the engagement and effectiveness of harm reduction programs. Methods: This study provides an initial evaluation of a hybrid recovery community organization providing PRSS as well as peer-based harm reduction services via a syringe exchange program. Administrative data collected during normal operations of the …

A Tale Of Two Democrats: How Authoritarianism Divides The Democratic Party, Julie Wronski, Alexa Bankert, Karyn Amira, April Johnson, Lindsey Levitan Oct 2018

A Tale Of Two Democrats: How Authoritarianism Divides The Democratic Party, Julie Wronski, Alexa Bankert, Karyn Amira, April Johnson, Lindsey Levitan

Faculty Articles

Authoritarianism has been predominantly used in American politics as a predictor of Republican identification and conservative policy preferences. We argue that this approach has neglected the role authoritarianism plays among Democrats and how it can operate within political parties regardless of their ideological orientation. Drawing from three distinct sets of data, we demonstrate the impact of authoritarianism in the 2016 Democratic Party’s primaries. Authoritarianism consistently predicts differences in primary voting among Democrats, particularly support for Hillary Clinton over Bernie Sanders. This effect is robust across various model specifications including controls for ideology, partisan strength, and other predispositions. These results highlight …


Disorder Induced Power-Law Gaps In An Insulator-Metal Mott Transition, Zhenyu Wang, Yoshinori Okada, Jared O'Neal, Wenwen Zhou, Daniel Walkup, Chetan Dhital, Tom Hogan, Patrick Clancy, Young-June Kim, Y. F. Hu, Luiz H. Santos, Stephen D. Wilson, Nandini Trivedi, Vidya Madhavan Oct 2018

Faculty Articles

A correlated material in the vicinity of an insulator-metal transition (IMT) exhibits rich phenomenology and variety of interesting phases. A common avenue to induce IMTs in Mott insulators is doping, which inevitably leads to disorder. While disorder is well known to create electronic inhomogeneity, recent theoretical studies have indicated that it may play an unexpected and much more profound role in controlling the properties of Mott systems. Theory predicts that disorder might play a role in driving a Mott insulator across an IMT, with the emergent metallic state hosting a power law suppression of the density of states (with exponent …

This study investigated the effect of branched-chain amino acid (BCAA) supplementationon recovery from eccentric exercise. Twenty males ingested either a BCAA supplement or placebo(PLCB) prior to and following eccentric exercise. Creatine kinase (CK), vertical jump (VJ), maximalvoluntary isometric contraction (MVIC), jump squat (JS) and perceived soreness were assessed.No significant (p> 0.05) group by time interaction effects were observed for CK, soreness, MVIC, VJ,or JS. CK concentrations were elevated above baseline (p< 0.001) in both groups at 4, 24, 48 and 72 hr,while CK was lower (p= 0.02) in the BCAA group at 48 hr compared to PLCB. Soreness increasedsignificantly from baseline (p< 0.01) in both groups at all time-points; however, BCAA supplementedindividuals reported less soreness (p< 0.01) at the 48 and 72 hr time-points. MVIC force outputreturned to baseline levels (p> 0.05) at 24, 48 and 72 hr for BCAA individuals. No significant differencebetween groups (p> 0.05) was detected for VJ or JS. BCAA supplementation may mitigate musclesoreness following muscle-damaging …

Perceptions Of Undergraduate Students Of Student-Regulated Online Courses, Victor K. Wakeling Cfa Cfp Cma, Patricia R. Robertson, Micheal Patrono, Murat Doral

Faculty Articles

Undergraduate students at a large, public, southeastern university enrolled in one of two independent, fully-online courses were released from the instructor-regulated structure mid-semester. Subsequently, the course was structured as student-regulated and students self-managed pace of study and timing of assessments for the remainder of the course. The objective of the research is to assess student preferences in learning structure (instructor-regulated versus student-regulated) in order to inform effective course design options in the online learning environment. At the end of each semester included in the study, a survey was administered to ascertain students’ perceptions of the student-regulated (self-paced) learning environment. After …


Market Power And Antitrust Enforcement, John B. Kirkwood Oct 2018

Market Power And Antitrust Enforcement, John B. Kirkwood

Faculty Articles

Antitrust is back on the national agenda. The Democratic Party, leading Senators, progressive organizations, and many scholars are calling for stronger antitrust enforcement. One important step, overlooked in the discussion to date, is to reform how market power — an essential element in most antitrust violations — is determined. At present the very definition of market power is unsettled. While there is widespread agreement that market power is the ability to raise price profitably above the competitive level, there is no consensus on how to determine the competitive level. Moreover, courts virtually never measure market power (or its larger variant, …


Environmental Governance And The Global South, Jeffrey Minneti Oct 2018

Environmental Governance And The Global South, Jeffrey Minneti

Faculty Articles

Over the last several decades, efforts to regulate the environment through traditional public law at national and international levels have stalled. In contrast, private environmental governance has flourished as nongovernmental entities have engaged in standard setting and assessment practices traditionally left to public government. Such entities include the Forest Stewardship Council (FSC) and Rainforest Alliance, both of which are nongovernmental entities that prescribe environmental standards for producers, provide labels and logos for producers that choose to comply with the standards, and maintain compliance through independent audits. The schemes incentivize environmentally responsible products and production processes by linking producers who conform …

Milking The Estate, David R. Hague Oct 2018

Milking The Estate, David R. Hague

Faculty Articles

Recent Chapter 7 bankruptcy cases are exposing a widespread problem. Chapter 7 trustees are retaining their own law firms to represent them and then in clear breach of their fiduciary duties to creditors-requesting illegitimate legal fees to be paid by the estate. This practice is immoral and particularly harmful to creditors. Indeed, every dollar paid to the trustee and his firm is a dollar that will not be distributed to creditors. The Bankruptcy Code, remarkably, allows a trustee to retain his own law firm to represent him in his capacity as a trustee. But this inherently conflicted arrangement is not …

Top Tagging: An Analytical Perspective, Mrinal Dasgupta, Marco Guzzi, Jacob Rowling, Gregory Soyez Sep 2018

Top Tagging: An Analytical Perspective, Mrinal Dasgupta, Marco Guzzi, Jacob Rowling, Gregory Soyez

Faculty Articles

In this paper we study aspects of top tagging from first principles of QCD. We find that the method known as the CMS top tagger becomes collinear unsafe at high pt and propose variants thereof which are IRC safe, and hence suitable for analytical studies, while giving a comparable performance to the CMS tagger. We also develop new techniques to identify three-pronged jet substructure, based on adaptations of the Y-splitter method and its combination with grooming. A novel feature of our studies, relative to previous calculations of two-pronged substructure, is our use of triple-collinear splitting functions combined with all-order resummation, …


The Distribution And Lifetime Of Powerful Radio Galaxies As A Function Of Environment And Redshift, David Garofalo, Chandra B. Singh, Alexa Zack Sep 2018

The Distribution And Lifetime Of Powerful Radio Galaxies As A Function Of Environment And Redshift, David Garofalo, Chandra B. Singh, Alexa Zack

Faculty Articles

Correlations between jet power and active time for z < 0.1 high excitation and low excitation radio galaxies are explored as well as evidence in favor of a specific, non-random distribution for these objects including mid-infrared emitting radio galaxies as a function of environment and redshift. In addition, so-called weak line radio galaxies with FRII jet morphology have been identified as a class of active galaxies in the process of shutting down. This paper identifies common features between these seemingly disparate phenomena described above for the population of radio galaxies, and strings them together by way of a simple phenomenological framework that has shed light on the radio loud/radio quiet dichotomy, the jet-disk connection, and the distribution of all active galaxies as a function of redshift.

Archean Phosphorus Liberation Induced By Iron Redox Geochemistry, Barry Herschy, Sae Jung Chang, Ruth Blake, Aivo Lepland, Heather Abbott-Lyon, Jacqueline Sampson, Zachary Atlas, Terence P. Kee, Matthew A. Pasek

Faculty Articles

The element phosphorus (P) is central to ecosystem growth and is proposed to be a limiting nutrient for life. The Archean ocean may have been strongly phosphorus-limited due to the selective binding of phosphate to iron oxyhydroxide. Here we report a new route to solubilizing phosphorus in the ancient oceans: reduction of phosphate to phosphite by iron(II) at low (<200 >°C) diagenetic temperatures. Reduction of phosphate to phosphite was likely widespread in the Archean, as the reaction occurs rapidly and is demonstrated from thermochemical modeling, experimental analogs, and detection of phosphite in early Archean rocks. We further demonstrate that the …

How The U.S. Supreme Court Deemed The Workers' Compensation Grand Bargain 'Adequate' Without Defining Adequacy, Michael C. Duff

Faculty Articles

During the second and third decades of the twentieth century the U S Supreme Court issued a handful of opinions rejecting 14th Amendment constitutional challenges by employers to implementation of workers' compensation statutes in the United States Unknown to many the statutes were largely the fruit of privatelysponsored investigations principally by the Russell Sage Foundation and the National Association of Manufacturers of European workers' compensation systems during the first decade of the twentieth century Some of those systems had been in existence since the 1870s and 1880s and many employers preferred them to newlyemerging American employer liability statutes that retained …

Resistance training may differentially affect morphological adaptations along the length of uni-articular and bi-articular muscles. The purpose of this study was to compare changes in muscle morphology along the length of the rectus femoris (RF) and vastus lateralis (VL) in response to resistance training. Following a 2-wk preparatory phase, 15 resistance-trained men (24.0 ± 3.0 y, 90.0 ± 13.8 kg, 174.9 ± 20.7 cm) completed pre-training (PRE) assessments of muscle thickness (MT), pennation angle (PA), cross-sectional area (CSA), and echo-intensity in the RF and VL at 30, 50, and 70% of each muscle’s length; fascicle length (FL) was estimated from …


Normative Values For Self-Reported Benchmark Workout Scores In Crossfit® Practitioners, Gerald T. Mangine, Brant Cebulla, Yuri Feito Aug 2018

Normative Values For Self-Reported Benchmark Workout Scores In Crossfit® Practitioners, Gerald T. Mangine, Brant Cebulla, Yuri Feito

Faculty Articles

Background: CrossFit® practitioners commonly track progress by monitoring their ability to complete a variety of standardized benchmark workouts within a typical class setting. However, objective assessment of progress is challenging because normative data does not currently exist for any of these benchmark workouts. Therefore, the purpose of this study was to develop normative values for five common benchmark workouts (i.e., Fran, Grace, Helen, Filthy-50 [F50], and Fight-Gone-Bad [FGB]). Methods: Performance data from 133,857 male (M) and female (F) profiles located on a publicly available website were collected and sorted by sex (i.e., male [M] and female [F]) and competitive age …
