    Reforming Buffalo\u27s Tax Foreclosure Process

    Get PDF
    The City of Buffalo holds an annual foreclosure auction to collect on delinquent taxes and fees owed by its residents. This is a way for the City to raise revenue that would otherwise go unpaid and for Buffalo citizens to buy buildings and lots at bargain prices. But the foreclosure process is imposing a high cost upon some of Buffalo’s most vulnerable citizens, creating an unnecessary burden on people trying to stay in their homes, and adding to the already existing epidemic of housing abandonment and blight

    Information Literacy in a Post-Truth Era

    The founders of American democracy believed it could not survive without an “informed citizenry”. What does an informed citizenry look like in today’s world? And what role do we have as educators and students to support it? First, we look at the significant challenges to institutional and media legitimacy that emerged in the second half of the 20th century, which rightfully called attention to the ways longstanding Western knowledge practices excluded marginalized communities and silenced important histories. We ask about the status of norms and mores in the aftermath of this challenge, in an era often called “post-truth.” Second, we consider the challenges of teaching information literacy. To the extent that we teach it at all, how have our instructions to “do the research” and “avoid fake news” failed? We invite instructors to interrogate their own information literacy practices (which are typically invisible); and to understand, empathize with, and value students’ information literacy practices. Jeffery Gonzalez, Assistant Professor of English, teaches courses on 20th and 21st century American literature. His research and writing explore how literary forms and narratives relate to economic, political, and social concerns. He has published essays in the academic journals Critique, Mosaic, and College Literature, among others. Catherine Baird, Online and Outreach Librarian, teaches and studies information literacy, and her recent publications examine MSU faculty and students. She and collaborator Jonathan Howell, Associate Professor of Linguistics, have written and presented on librarian-faculty collaboration. Their current book project, Teaching Information Literacy, offers faculty an accessible and practical introduction to recent research in the learning and information sciences

    Insulation for Daydreams: A Role for Tonic Norepinephrine in the Facilitation of Internally Guided Thought

    Although consciousness can be brought to bear on both perceptual and internally generated information, little is known about how these different cognitive modes are coordinated. Here we show that between-participant variance in thoughts unrelated to the task being performed (known as task unrelated thought, TUT) is associated with longer response times (RT) when target presentation occurs during periods when baseline Pupil Diameter (PD) is increased. As behavioral interference due to high baseline PD can reflect increased tonic activity in the norepinephrine system (NE), these results might implicate high tonic NE activity in the facilitation of TUTs. Based on these findings, it is hypothesised that high tonic mode NE leads to a generalised de-amplification of task relevant information that prioritses internally generated thought and insulates it from the potentially disruptive events taking place in the external environment

    The Decoupled Mind : Mind-wandering Disrupts Cortical Phase-locking to Perceptual Events

    The mind flows in a "stream of consciousness," which often neglects immediate sensory input in favor of focusing on intrinsic, self-generated thoughts or images. Although considerable research has documented the disruptive influences of task-unrelated thought for perceptual processing and task performance, the brain dynamics associated with these phenomena are not well understood. Here we investigate the possibility, suggested by several convergent lines of research, that task-unrelated thought is associated with a reduction in the trial-to-trial phase consistency of the oscillatory neural signal in response to perceptual input. Using an experience sampling paradigm coupled with continuous high-density electroencephalography, we observed that task-unrelated thought was associated with a reduction of the P1 ERP, replicating prior observations that mind-wandering is accompanied by a reduction of the brain-evoked response to sensory input. Time-frequency analysis of the oscillatory neural response revealed a decrease in theta-band cortical phase-locking, which peaked over parietal scalp regions. Furthermore, we observed that task-unrelated thought impacted the oscillatory mode of the brain during the initiation of a task-relevant action, such that more cortical processing was required to meet task demands. Together, these findings document that the attenuation of perceptual processing that occurs during task-unrelated thought is associated with a reduction in the temporal fidelity with which the brain responds to a stimulus and suggest that increased neural processing may be required to recouple attention to a task. More generally, these data provide novel confirmatory evidence for the mechanisms through which attentional states facilitate the neural processing of sensory input

    Contrast-Induced Neurotoxicity following Cardiac Catheterization

    We report a case of probable contrast-induced neurotoxicity that followed a technically challenging cardiac catheterization in a 69-year-old woman. The procedure had involved the administration of a large cumulative dose of an iodinated, nonionic contrast medium into the innominate artery: twelve hours following the catheterization, the patient developed a seizure followed by a left hemiplegia, and an initial computed tomography (CT) scan showed sulcal effacement in the right cerebral hemisphere due to cerebral swelling. The patient’s clinical symptoms resolved within 24 hours, and magnetic resonance imaging at 32 hours showed resolution of swelling. Contrast-induced neurotoxicity should be found in the differential diagnosis of acute neurological deficits occurring after radiological procedures involving iodinated contrast media, whether ionic or nonionic

    Regional White Matter Variation Associated with Domain-specific Metacognitive Accuracy

    The neural mechanisms that mediate metacognitive ability (the capacity to accurately reflect on one's own cognition and experience) remain poorly understood. An important question is whether metacognitive capacity is a domain-general skill supported by a core neuroanatomical substrate or whether regionally specific neural structures underlie accurate reflection in different cognitive domains. Providing preliminary support for the latter possibility, recent findings have shown that individual differences in metacognitive ability in the domains of memory and perception are related to variation in distinct gray matter volume and resting-state functional connectivity. The current investigation sought to build on these findings by evaluating how metacognitive ability in these domains is related to variation in white matter microstructure. We quantified metacognitive ability across memory and perception domains and used diffusion spectrum imaging to examine the relation between high-resolution measurements of white matter microstructure and individual differences in metacognitive accuracy in each domain. We found that metacognitive accuracy for perceptual decisions and memory were uncorrelated across individuals and that metacognitive accuracy in each domain was related to variation in white matter microstructure in distinct brain areas. Metacognitive accuracy for perceptual decisions was associated with increased diffusion anisotropy in white matter underlying the ACC, whereas metacognitive accuracy for memory retrieval was associated with increased diffusion anisotropy in the white matter extending into the inferior parietal lobule. Together, these results extend previous findings linking metacognitive ability in the domains of perception and memory to variation in distinct brain structures and connections

    Is Streptococcus pyogenes resistant or susceptible to Trimethoprim-Sulfamethoxazole?

    Streptococcus pyogenes is commonly believed to be resistant to trimethoprim-sulfamethoxazole (SXT), resulting in reservations about using SXT for skin and soft tissue infections (SSTI) where S. pyogenes is involved. S. pyogenes\u27 in vitro susceptibility to SXT depends on the medium\u27s thymidine content. Thymidine allows S. pyogenes to bypass the sulfur-mediated inhibition of folate metabolism and, historically, has resulted in apparently reduced susceptibility of S. pyogenes to sulfur antibacterials. The low thymidine concentration in Mueller-Hinton agar (MHA) is now regulated. We explored S. pyogenes susceptibility to SXT on various media. Using two sets of 100 clinical S. pyogenes isolates, we tested for susceptibility using SXT Etests on MHA containing defibrinated horse blood and 20 mg/liter β-NAD (MHF), MHA with sheep blood (MHS), MHA alone, MHA with horse blood (MHBA), and MHA with lysed horse blood (MHLHBA). European Committee on Antibacterial Susceptibility Testing (EUCAST) breakpoints defined susceptibility (MIC, ≤1 mg/liter) and resistance (MIC, >2 mg/liter). In study 1, 99% of S. pyogenes isolates were susceptible to SXT on MHA, MHBA, and MHLHBA, with geometric mean MICs of 0.04, 0.04, and 0.05 mg/liter, respectively. In study 2, all 100 S. pyogenes isolates were susceptible to SXT on MHF, MHS, MHA, and MHLHBA with geometric mean MICs of 0.07, 0.16, 0.07, and 0.09 mg/liter, respectively. This study confirms the in vitro susceptibility of S. pyogenes to SXT, providing support for the use of SXT for SSTIs. A clinical trial using SXT for impetigo is ongoing
