AbstractEnhanced temporal and spatial resolution of the Geostationary Operational Environmental Satellite–R Series (GOES-R) will allow for the use of cloud-top-cooling-based convection-initiation (CI) forecasting algorithms. Two such algorithms have been created on the current generation of GOES: the University of Wisconsin cloud-top-cooling algorithm (UWCTC) and the University of Alabama in Huntsville’s satellite convection analysis and tracking algorithm (SATCAST). Preliminary analyses of algorithm products have led to speculation over preconvective environmental influences on algorithm performance. An objective validation approach is developed to separate algorithm products into positive and false indications. Seventeen preconvective environmental variables are examined for the positive and false indications to improve algorithm output. The total dataset consists of two time periods in the late convective season of 2012 and the early convective season of 2013. Data are examined for environmental relationships using principal component analysis (PCA) and quadratic discriminant analysis (QDA). Data fusion by QDA is tested for SATCAST and UWCTC on five separate case-study days to determine whether application of environmental variables improves satellite-based CI forecasting. PCA and significance testing revealed that positive indications favored environments with greater vertically integrated instability (CAPE), less stability (CIN), and more low-level convergence. QDA improved both algorithms on all five case studies using significantly different variables. This study provides an examination of environmental influences on the performance of GOES-R Proving Ground CI forecasting algorithms and shows that integration of QDA in the cloud-top-cooling-based algorithms using environmental variables will ultimately generate a more skillful product.

This case study of the University of Alabama’s Where Legends Are Made illustrates how a 30-s television advertisement with a catchy tagline was transformed into a strategic branding campaign that communicated the essence of the university in a compelling story. Employing a qualitative methodology, the case study drew on personality archetypes to develop an institutional brand communication management conceptual framework that illustrated the guiding principles and creative contexts used to break through the communication clutter. It did so by emphasizing the University of Alabama’s leadership, competitive spirit, and transformative innovation by making its fabled athletic tradition an extension of its everyday excellence in academic disciplines. It also demonstrated how empirically tested archetype personas can be effectively employed in persuasive storylines to emotionally resonate with key stakeholders and prospective consumers alike, with each interpreting it in a way that is compatible with their own values, lifestyles, and culture.

Purpose – As a model of competency-based education (CBE), the University of Wisconsin (UW) System Flex options present a unique case study of challenges and opportunities for embedding student-centered library services and information literacy. Design/methodology/approach – In this paper, we describe strategies for engaging with the evolving Flex curriculum, the needs of an unknown student body and the role of new student support staff. The author notes the relevance of examining the library’s role in Flex at this time, given the potential for growth nationally in CBE. Findings – The challenges the author faced initially were closely tied with opportunities that once examined, formed the basis of the embedded library model for competency-based education. Further, the author found opportunities to articulate their role in Flex on their campus and share with other institutions. Originality/value – This case study is based on the author’s experiences embedding Information Literacy and Distance Services in the Flex option at the University of Wisconsin Milwaukee.

This case study illustrates the value of intellectual capital measurement, specific to human capital and innovation capital within an academic unit at a University of Wisconsin System campus. Within the case study, the academic unit was audited for their innovation practices and then examined to identify the value of human capital on their front line employees. Innovation continues to be a crucial component within academia as well as organizations in general to provide a competitive advantage. Understanding the value front line employees brings to a non-profit organization in academia continues to be a growing concern for many Universities'. The case study contains three parts; an innovation audit, several models and formulas to understand the value of human capital within a particular academic unit, and an overall conclusion and recommendation will be given for the current academic unit at the University of Wisconsin System campus.

This case study explores how one team tasked with the creation of digital collections at The University of Alabama Libraries succeeded at telework to carry on its essential functions despite not being able to digitize new content from March through July 2020 during the COVID-19 pandemic. Managers of similar units will gain strategies to create similar telework projects at their institution and lessons learned while working and supervising employees remotely.

The University of Wisconsin-Stout Asynchronous Learning Network (ALN) project, funded by the Alfred P. Sloan Foundation, represents an effort to expand the boundaries of the traditional campus. The purpose of this project was to offer learning opportunities to both traditional students and industry professionals either on campus or away from the campus. The asynchronous method of delivery will allow learners to participate from any place at any time. This paper will review how the University of Wisconsin-Stout is using technology to remove learning barriers and provide students with learning options. The focus of this paper is to provide a detailed explanation of the process the University of Wisconsin-Stout used to implement an Asynchronous Learning Network. It will describe the history and background of the project, design and development issues, results and proposed next steps for this campus.

Objective: To report a case of a patient with recent mild to moderate COVID-19 infection who developed tumefactive acute disseminated encephalomyelitis. Methods: Patient data were obtained from medical records from the University of Wisconsin – Madison Hospitals in Madison, WI, USA. Results: We report a 59-year-old man with past medical history notable for atrial fibrillation, biventricular pacemaker, end-stage renal disease secondary to idiopathic fibrillary glomerulonephritis, on hemodialysis awaiting transplantation, who presented with ongoing cognitive changes and pneumonia. He was repeatedly COVID-19 positive with minimal symptoms for 4 weeks prior to admission. He developed right sided hemiparesis and persistent, progressive encephalopathy manifesting primarily with disorientation, agitation, and aggression. CSF was notable for cell count of 7, protein of 48, and glucose of 65. Anti-MOG antibody and AQP-4 antibody were negative. A series of CT/CTA head imaging with and without contrast showed progressive multifocal supratentorial areas of white matter hypoattenuation and MRI head with and without contrast demonstrated progressive multi-focal large ovoid T2 FLAIR hyperintensities, partially ring enhancing on contrasted portion of study, consistent with tumefactive demyelinating disease. Significant improvement in mental status and right sided hemiparesis symptoms was observed with initiation of corticosteroids. Conclusion: This case study provides neuroimaging evidence and clinical correlation to support that SARS–CoV-2 and resultant COVID-19 infection can lead to tumefactive acute disseminated encephalomyelitis. This complication has not been previously documented associated with recent COVID-19 infection.
