Cortical And Subcortical Contributions To Neuroplasticity After Repetitive Transspinal Stimulation In Humans, Lynda M. Murray, Anamul Islam Md., Maria Knikou

Publications and Research

The objectives of this study were to establish cortical and subcortical contributions to neuroplasticity induced by noninvasive repetitive transspinal stimulation in human subjects free of any neurological disorder. To meet our objectives, before and after 40 minutes of transspinal stimulation we established changes in tibialis anterior (TA) motor-evoked potentials (MEPs) in response to paired transcranial magnetic stimulation (TMS) pulses at interstimulus intervals (ISIs) consistent with I-wave periodicity. In order to establish to what extent similar actions are exerted at the spinal cord and motor axons, changes in soleus H-reflex and transspinal evoked potential (TEP) amplitude following transspinal and group Ia …

Cultural Transmission Modes Of Music Sampling Traditions Remain Stable Despite Delocalization In The Digital Age, Mason Youngblood

Publications and Research

Music sampling is a common practice among hip-hop and electronic producers that has played a critical role in the development of particular subgenres. Artists preferentially sample drum breaks, and previous studies have suggested that these may be culturally transmitted. With the advent of digital sampling technologies and social media the modes of cultural transmission may have shifted, and music communities may have become decoupled from geography. The aim of the current study was to determine whether drum breaks are culturally transmitted through musical collaboration networks, and to identify the factors driving the evolution of these networks. Using network-based diffusion analysis …

Changes In Functional Connectivity Following Treatment With Emotion Regulation Therapy, Matthew A. Scult, David M. Fresco, Faith M. Gunning, Conor Liston, Saren H. Seeley, Emmanuel Garcia, Douglas S. Mennin

Publications and Research

Emotion regulation therapy (ERT) is an efficacious treatment for distress disorders (i.e., depression and anxiety), predicated on a conceptual model wherein difficult to treat distress arises from intense emotionality (e.g., neuroticism, dispositional negativity) and is prolonged by negative self-referentiality (e.g., worry, rumination). Individuals with distress disorders exhibit disruptions in two corresponding brain networks including the salience network (SN)reflecting emotion/motivation and the default mode network (DMN) reflecting self-referentiality. Using resting-state functional connectivity (rsFC) analyses, seeded with primary regions in each of these networks, we investigated whether ERT was associated with theoretically consistent changes across nodes of these networks and whether these …

“In The Beginning Was Body Language” Clowning And Krump As Spiritual Healing And Resistance, Sarah S. Ohmer

Publications and Research

In the neighborhood of HollyWatts in Los Angeles, dance allows a shift from existing as bodies presented as sites of threat and extinction to sources of spiritual empowerment. Clowning and Krump dancers—their subjectivity and their dancing bodies—negotiate survival from trauma and socioeconomic marginalization. I argue that the dancers’ performances act as embodied narratives of “re-membering in the flesh.” The performance acts as a spiritual retrieval and re-integration of traumatic memories and afflictions into memory through the body. Choreography and quotes from dancers support the claim that Krump and Clowning is “re-membering in the flesh” that enacts self-worth, self-defined sexuality, and …

Obfuscating Authorship: Results Of A User Study On Nondescript, A Digital Privacy Tool, Robin Camille Davis

Publications and Research

For those who write anonymously, particularly for safety reasons, authorship attribution poses a threat. Nondescript, my web app, guides writers in achieving stylometric obfuscation in order to preserve anonymity. The app runs simulations of authorship attribution scenarios by analyzing the user’s linguistic features. In this paper, I will describe the conception of the Nondescript app; discuss related work; and present the results of a user study. Most users in the study were able to anonymize their writing in at least 5 out of 10 authorship attribution scenarios. Users rated the anonymization process an average of 3.6 out of 5 in …

Cognitive, Behavioral, And Situational Influences On Relapse To Smoking After Group Treatment For Tobacco Dependence, Sara E. Lunden, Jami C. Pittman, Neelam Prashad, Ria Malhotra, Christine Sheffer

Publications and Research

Socioeconomic disparities in treatment failure rates for evidence-based tobacco dependence treatment are well-established. Adapted cognitive behavioral treatments are extensively tailored to meet the needs of lower socioeconomic status (SES) smokers and dramatically improve early treatment success, but there is little understanding of why treatment failure occurs after a longer period of abstinence than with standard treatment, why early treatment success is not sustained, and why long-term treatment failure rates are no different from standard treatments. We sought to understand the causes of treatment failure from the perspective of diverse participants who relapsed after receiving standard or adapted treatment in a …

Bridging The Research/Teaching Divide With Dah And Sotl-Ah, Renee Mcgarry, Virginia B. Spivey Phd

Publications and Research

This paper explores the potential for rigorous pedagogical scholarship to complement developments in digital art history (DAH). In addition to introducing ideas and methods that characterize scholarship of teaching and learning (SOTL) in higher education, we focus on two major themes: how digital tools and techniques can support robust scholarship of teaching and learning in art history (SoTL-AH) and ways that SoTL-AH can be used to evaluate and demonstrate the impact of DAH projects in the classroom and the public realm. Our goal is to encourage greater exchange between these two emerging fields that can together advance art historical study.

An Exploratory Study Of Police Officers: Low Compassion Satisfaction And Compassion Fatigue, Heath Blair Grant, Cathryn F. Lavery, John Decarlo

Publications and Research

Background: Compassion fatigue, or the physical, mental, and emotional state experienced by professionals that assist others in distress, has been well documented in several caring professions such as nurses, firefighters, and emergency medical technicians. Until the current study, it has only rarely been examined in police samples despite their high rates of stress and suicide which is a likely result of a depletion of compassion satisfaction, or the pleasure an officer gets from relating to and helping others.

Aim: This study documents findings from an ongoing study of compassion fatigue amongst a sample of US urban police officers which suggests …

Publications and Research

The roles of retinoids in nonalcoholic fatty liver disease (NAFLD) remain unclear and a better understanding may lead to therapies that prevent or limit NAFLD progression. We examined the actions of retinoic acid receptor (RAR) agonists- AM80 for RARαand AC261066 for RARβ2- in a murine model of NAFLD. We fed wild type C57Bl/6 mice a chow or a 45% high fat diet (HFD) for 12 weeks, followed by 4 additional weeks with the HFD+AM80; HFD +AC261066; or HFD. The HFD+AM80 group showed greater hyperglycemia and glucose intolerance compared to other groups. Histopathological evaluation of the livers showed the highest degree …

Peculiar Optical Properties Of Bilayer Silicene Under The Influence Of External Electric And Magnetic Fields, Thi-Nga Do, Godfrey Gumbs, Po-Hsin Shih, Danhong Huang, Chih-Wei Chiu, Chia-Yun Chen, Ming-Fa Lin

Publications and Research

We conduct a comprehensive investigation of the effect of an applied electric field on the optical and magneto-optical absorption spectra for AB-bt (bottom-top) bilayer silicene. The generalized tightbinding model in conjunction with the Kubo formula is efficiently employed in the numerical calculations. The electronic and optical properties are greatly diversified by the buckled lattice structure, stacking configuration, intralayer and interlayer hopping interactions, spin-orbital couplings, as well as the electric and magnetic fields (Ez ˆz & Bz ˆz ). An electric field induces spin-split electronic states, a semiconductor-metal phase transitions and the Dirac cone formations in different valleys, leading to the …

Geoarchaeological Evidence Of Middle-Age Tsunamis At Stromboli And Consequences For The Tsunami Hazard In The Southern Tyrrhenian Sea, M. Rosi, S. T. Levi, M. Pistolesi, A. Bertagnini, D. Brunelli, V. Cannavo, A. Di Renzoni, F. Ferranti, A. Renzulli, D. Yoon

Publications and Research

Large-scale landslides at volcanic islands are one of the most dangerous geological phenomena, able to generate tsunamis whose effects can propagate far from the source. However, related deposits are scarcely preserved on-land in the geologic records, and are often difficult to be interpreted. Here we show the discovery of three unprecedented well-preserved tsunami deposits related to repeated flank collapses of the volcanic island of Stromboli (Southern Italy) occurred during the Late Middle Ages. Based on carbon datings, on stratigraphic, volcanological and archaeological evidence, we link the oldest, highest-magnitude investigated tsunami to the following rapid abandonment of the island which was …

Biotransformed Metabolites Of The Hop Prenylflavanone Isoxanthohumol, Hyun Jung Kim, Soon-Ho Yim, Fubo Han, Bok Yun Kang, Hyun Jin Choi, Da-Woon Jung, Darren R. Williams, Kirk R. Gustafson, Edward J. Kennelly, Ik-Soo Lee

Publications and Research

A metabolic conversion study on microbes is known as one of the most useful tools to predict the xenobiotic metabolism of organic compounds in mammalian systems. The microbial biotransformation of isoxanthohumol (1), a major hop prenylflavanone in beer, has resulted in the production of three diastereomeric pairs of oxygenated metabolites (2–7). The microbial metabolites of 1 were formed by epoxidation or hydroxylation of the prenyl group, and HPLC, NMR, and CD analyses revealed that all of the products were diastereomeric pairs composed of (2S)- and (2R)- isomers. The structures of these metabolic compounds were elucidated to be (2S,200S)- and (2R,200S)-40 …

Putative Cellular And Molecular Roles Of Zika Virus In Fetal And Pediatric Neuropathologies, Rajendra Ghardbaran, Rajendra Ghardbaran, Latchman Somenarain

Publications and Research

Although the World Health Organization declared an end to the recent Zika virus (ZIKV) outbreak and its association with adverse fetal and pediatric outcome, on November 18, 2016, the virus still remains a severe public health threat. Laboratory experiments thus far supported the suspicions that ZIKV is a teratogenic agent. Evidence indicated that ZIKV infection cripples the host cells' innate immune responses, allowing productive replication and potential dissemination of the virus. In addition, studies suggest potential transplacental passage of the virus and subsequent selective targeting of neural progenitor cells (NPCs). Depletion of NPCs by ZIKV is associated with restricted brain …

Microrna-4719 And Microrna-6756-5p Correlate With Castration-Resistant Prostate Cancer Progression Through Interleukin-24 Regulation, Dibash K. Das, Leah Persaud, Moira Sauane

Publications and Research

Prostate cancer (PCa) is the second leading cause of cancer death in the United States. The five-year survival rate for men diagnosed with localized PCa is nearly 100%, yet for those diagnosed with aggressive PCa, it is less than 30%. The pleiotropic cytokine Interleukin-24 (IL-24) has been shown to specifically kill PCa cells compared to normal cells when overexpressed in both in vitro and in vivo studies. Despite this, the mechanisms regulating IL-24 in PCa are not well understood. Since specific microRNAs (miRNAs) are dysregulated in PCa, we used miRNA target prediction algorithm tools to identify miR-4719 and miR-6556-5p as …

Standards For Distribution Models In Biodiversity Assessments, Miguel B. Araújo, Robert P. Anderson, A. Márcia Barbosa, Colin M. Beale, Carsten F. Dormann, Regan Early, Raquel A. Garcia, Antoine Guisan, Luigi Maiorano, Babak Naimi, Robert B. O'Hara, Niklaus E. Zimmermann, Carsten Rahbek

Publications and Research

Demand for models in biodiversity assessments is rising, but which models are adequate for the task? We propose a set of best-practice standards and detailed guidelines enabling scoring of studies based on species distribution models for use in biodiversity assessments. We reviewed and scored 400 modeling studies over the past 20 years using the proposed standards and guidelines. We detected low model adequacy overall, but with a marked tendency of improvement over time in model building and, to a lesser degree, in biological data and model evaluation. We argue that implementation of agreed-upon standards for models in biodiversity assessments would …

Deletion Of Mgr2p Affects The Gating Behavior Of The Tim23 Complex, Oygul Mirzalieva, Shinhye Jeon, Kevin Damri, Ruth Hartke, Layla Drwesh, Keren Demishtein-Zohary, Abdussalam Azem, Cory D. Dunn, Pablo M. Peixoto

Publications and Research

The TIM23 complex is a hub for translocation of preproteins into or across the mitochondrial inner membrane. This dual sorting mechanism is currently being investigated, and in yeast appears to be regulated by a recently discovered subunit, the Mgr2 protein. Deletion of Mgr2p has been found to delay protein translocation into the matrix and accumulation in the inner membrane. This result and other findings suggested that Mgr2p controls the lateral release of inner membrane proteins harboring a stop-transfer signal that follows an N-terminal amino acid signal. However, the mechanism of lateral release is unknown. Here, we used patch clamp electrophysiology …

A Writing Assignment To Address Gaps In The Nursing Curriculum Regarding Health Issues Of Lgbt+ Populations., Bridget Maley, Randy Gross

Publications and Research

Background: LGBT+ populations account for 4% of the US population, yet health disparities persist, which are considered a priority in health care systems. In nursing education programs, the allotment in time to cover LGBT+ health content is not mandated thus ranges from zero to several hours total in nursing curricula. Therefore, nursing students’ education regarding LGBT+ health issues remains minimal and inconsistent throughout the nation’s nursing programs.

Aim: To provide associate degree nursing students with exposure to the health disparities in LGBT+ populations through a reflective writing assignment.

Methods: The essays were culled from both sections of an established core …

Influence Of Fake News In Twitter During The 2016 Us Presidential Election, Alexandre Bovet, Hernán A. Makse

Publications and Research

The dynamics and influence of fake news on Twitter during the 2016 US presidential election remains to be clarified. Here, we use a dataset of 171 million tweets in the five months preceding the election day to identify 30 million tweets, from 2.2 million users, which contain a link to news outlets. Based on a classification of news outlets curated by www.opensources.co, we find that 25% of these tweets spread either fake or extremely biased news. We characterize the networks of information flow to find the most influential spreaders of fake and traditional news and use causal modeling to …

Adolescent Trials Network For Hiv-Aids Scale It Up Program: Protocol For A Rational And Overview, Sylvie Naar, Jeffrey T. Parsons, Bonita F. Stanton

Publications and Research

Background: The past 30 years have witnessed such significant progress in the prevention and treatment of HIV/AIDS that an AIDS-free generation and the end to the global AIDS epidemic are ambitious, but achievable, national and global goals. Despite growing optimism, globally, youth living with HIV are markedly less likely to receive antiretroviral therapy than adults (23% vs 38%).
