    May 25, 2020, exponentially reinvigorated a global reckoning around the uniquely American way of murdering Black people through policing and imprisonment. Calls for anti-racism, police reforms, and abolition permeated nearly every industry with statements, commitments, and trendy Instagram graphics. Once an idea reserved for the most radical, abolition entered the popular culture lexicon not only for its dedication to destroying oppressive systems but also for building communities of care. As student affairs professionals dedicated to community development at institutions built upon white supremacy and bound by federal policies, approaching community development through an abolitionist framework requires an imaginative playfulness to create new realities and a grounded conviction to effect tangible change for our most vulnerable communities. We welcome you to join us as we nerd out with theory, grapple with deeply personal questions, and offer practical ways abolition can bring us closer to creating communities of care

    Intriguing New Model for Improved Visibility and Access to Theses and Dissertations

    Get PDF
    The George A. Smathers Libraries at the University of Florida (UF) are participating in an innovative program to explore whether making electronic theses and dissertations (ETDs) available in print through online retail sites can have positive impacts for graduates, the University, and the general public. Digitization and metadata enhancement have improved discoverability and ease of access for ETDs in the Institutional Repository at the University of Florida (IR@UF). However, through this new program, research can be shared widely beyond academe with practitioners, corporate researchers, independent scholars, and international readers. This paper will describe how the Smathers Libraries have worked with a corporate partner, BiblioLabs, to leverage online retailers’ discovery engines to promote print versions of ETDs while alerting readers to the free digital versions available in the IR@UF. This paper will also share how alumni, current graduate students, and other campus stakeholders have responded to the pilot of this new service. The Libraries are monitoring referred traffic to the IR and sales data. UF is the first university to contribute content to this effort, but we expect others to follow suit if the data supports the expectations of the University, the Libraries, and our graduates

    B cells are capable of independently eliciting rapid reactivation of encephalitogenic CD4 T cells in a murine model of multiple sclerosis

    <div><p>Recent success with B cell depletion therapies has revitalized efforts to understand the pathogenic role of B cells in Multiple Sclerosis (MS). Using the adoptive transfer system of experimental autoimmune encephalomyelitis (EAE), a murine model of MS, we have previously shown that mice in which B cells are the only MHCII-expressing antigen presenting cell (APC) are susceptible to EAE. However, a reproducible delay in the day of onset of disease driven by exclusive B cell antigen presentation suggests that B cells require optimal conditions to function as APCs in EAE. In this study, we utilize an <i>in vivo</i> genetic system to conditionally and temporally regulate expression of MHCII to test the hypothesis that B cell APCs mediate attenuated and delayed neuroinflammatory T cell responses during EAE. Remarkably, induction of MHCII on B cells following the transfer of encephalitogenic CD4 T cells induced a rapid and robust form of EAE, while no change in the time to disease onset occurred for recipient mice in which MHCII is induced on a normal complement of APC subsets. Changes in CD4 T cell activation over time did not account for more rapid onset of EAE symptoms in this new B cell-mediated EAE model. Our system represents a novel model to study how the timing of pathogenic cognate interactions between lymphocytes facilitates the development of autoimmune attacks within the CNS.</p></div

    Academic Library and Publisher Collaboration: Utilizing an Institutional Repository to Maximize the Visibility and Impact of Articles by University Authors

    The George A. Smathers Libraries (Libraries) (http://www.uflib.ufl.edu/) at the University of Florida (UF) (http://www.ufl.edu/) and Elsevier (http://www.elsevier.com) have embarked on a pilot project to maximize visibility, impact, and dissemination of articles by UF researchers who have published in Elsevier journals. Article links and metadata are automatically delivered to UF’s Institutional Repository, the IR@UF (http://ufdc.ufl.edu/ir), in the IR@UF-Elsevier Collection (http://ufdc.ufl.edu/ielsevier). The metadata, with links for approximately 31,000 articles by UF authors, is made possible through integration of the IR@UF with the ScienceDirect application programming interfaces (APIs) (https://www.elsevier.com/solutions/sciencedirect/support/institutional-repository) that are freely available to libraries. Access to the full text on ScienceDirect is available for all institutional repository users affiliated with a subscribing institution. In the next phase users without subscriptions will be able to access the manuscripts of articles published from 2013 forward. This will be done by embedding metadata and links to accepted manuscripts available on ScienceDirect into the IR@UF. We will conduct user and usability testing of this cross-platform user experience. This article provides an overview of the project’s current status, how it works, what it delivers, and next steps expanding the project to include articles by UF authors from other publishers. It concludes with strategic considerations, future developments, and reflections on the value of library/publisher collaboration

    Spearmint (\u3cem\u3el\u3c/em\u3e-carvone) Oil and Wintergreen (methyl salicylate) Oil Emulsion is an Effective Immersion Anesthetic of Fishes

    This study evaluates the effects of a spearmint (/-carvone) and wintergreen oil (methyl salicylate) emulsion (CMSE) on age 1 landlocked Atlantic salmon Salmo salar sebago (hereafter salmon). Salmon were immersed in either 257 µl/L CMSE or 75 mg/L tricaine methanesulfonate (MS-222) to induce anesthesia (stage 4), useful for emersion and noninvasive husbandry procedures, and then salmon were recovered in fresh water. Induction was quicker in the CMSE group; however, recovery was quicker in the MS-222 group. A second experiment was conducted in which salmon were immersed in 257 µl/L CMSE for 8.5 min, or 75 mg/L MS-222 for 8.5 min in order to compare electrocardiographs during deeper anesthesia (stage 5) between salmon continuously immersed in CMSE to those continuously immersed in MS-222. Because salmon remained sedated longer after CMSE exposure than after MS-222 exposure, a third group of salmon was immersed in 257 µl/L CMSE for just 2.5 min before undergoing the 6-min electrocardiograph procedure. Anesthesia induction rates, recovery rates, and electrocardiographs of salmon anesthetized with CMSE were comparable to salmon anesthetized with MS-222. Salmon anesthetized with CMSE and then transferred immediately to fresh water had more stable heart rates than salmon anesthetized with either MS-222 or CMSE continuously. Salmon bathed continuously in CMSE showed clinical signs of increasing anesthetic depth including decreasing heart rate, decreasing respiration rate and electrocardiograph abnormalities. The CMSE, with its mint and wintergreen concentrations less than in household products such as chewing gum, toothpaste, and mouthwash, is a potent, rapid-acting immersion fish anesthetic comparable to MS-222 for stages 4 and 5 anesthesia

    Resolving the gap and AU-scale asymmetries in the pre-transitional disk of V1247 Orionis

    Pre-transitional disks are protoplanetary disks with a gapped disk structure, potentially indicating the presence of young planets in these systems. In order to explore the structure of these objects and their gap-opening mechanism, we observed the pre-transitional disk V1247 Orionis using the Very Large Telescope Interferometer, the Keck Interferometer, Keck-II, Gemini South, and IRTF. This allows us spatially resolve the AU-scale disk structure from near- to mid-infrared wavelengths (1.5 to 13 {\mu}m), tracing material at different temperatures and over a wide range of stellocentric radii. Our observations reveal a narrow, optically-thick inner-disk component (located at 0.18 AU from the star) that is separated from the optically thick outer disk (radii >46 AU), providing unambiguous evidence for the existence of a gap in this pre-transitional disk. Surprisingly, we find that the gap region is filled with significant amounts of optically thin material with a carbon-dominated dust mineralogy. The presence of this optically thin gap material cannot be deduced solely from the spectral energy distribution, yet it is the dominant contributor at mid-infrared wavelengths. Furthermore, using Keck/NIRC2 aperture masking observations in the H, K', and L' band, we detect asymmetries in the brightness distribution on scales of about 15-40 AU, i.e. within the gap region. The detected asymmetries are highly significant, yet their amplitude and direction changes with wavelength, which is not consistent with a companion interpretation but indicates an inhomogeneous distribution of the gap material. We interpret this as strong evidence for the presence of complex density structures, possibly reflecting the dynamical interaction of the disk material with sub-stellar mass bodies that are responsible for the gap clearing.Comment: 16 pages, 17 Figures, accepted by Astrophysical Journa

    Murine For a Bad Time: Prehospital Factor Associations With Murine Typhus Related ICU Admission

    Get PDF
    Introduction: Across South Texas rates of murine typhus related hospitalization have been on the rise (1). Murine typhus is flea borne febrile illness caused by the bacterium Rickettsia typhi. Murine typhus is easily treated with doxycycline but is commonly underdiagnosed (2). Rarely murine typhus can cause hospitalization and ICU admission (3). To gain a greater understanding of the clinical course of severe murine typhus, our team has set out to identify novel clinical findings associated severe murine typhus courses. Methods: Medical records were obtained from adults with suspected murine typhus admitted to Doctor’s Hospital at Renaissance in Edinburg, Texas, between 01/01/2010 to 05/31/2020. Authors performed manual chart review on the patients meeting the inclusion criteria and documented aspects of the patient’s medical history. Descriptive statistics were calculated with a χ2 test, were P values =0.05 were considered statistically significant. Results: We enrolled 198 hospitalized adults with suspected murine typhus in our study, 22 requiring ICU admission. No statistically significant relationships were found between ICU admission and PMH indications of: CKD, T2D, HTN, CAD or liver disease. Our results did not show significant relationships between ICU admission and sex, age, or insurance status. Conclusion: Our study did not identify statistically significant relationships between adults admitted to the ICU with suspected murine typhus and health history. The findings of our study may be useful for clinicians who practice in regions endemic to murine typhus. Our team will continue to attempt to identify clinical and laboratory findings associated with a more severe disease course of murine typhus
