Milagrito: a TeV air-shower array

Milagrito, a large, covered water-Cherenkov detector, was the world's first air-shower-particle detector sensitive to cosmic gamma rays below 1 TeV. It served as a prototype for the Milagro detector and operated from February 1997 to May 1998. This paper gives a description of Milagrito, a summary of the operating experience, and early results that demonstrate the capabilities of this technique.Comment: 38 pages including 24 figure

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses

To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1–11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common in COVID-19 than controls and some (including against MYL7, UCH-L1, and GRIN3B) are more frequent with altered consciousness. Additionally, convalescent participants with neurological complications show elevated GFAP and NfL, unrelated to attenuated systemic inflammatory mediators and to autoantibody responses. Overall, neurological complications of COVID-19 are associated with evidence of neuroglial injury in both acute and late disease and these correlate with dysregulated innate and adaptive immune responses acutely

Herbicide-Resistance in Turf Systems: Insights and Options for Managing Complexity

Due to complex interactions between social and ecological systems, herbicide resistance has classic features of a “wicked problem.” Herbicide-resistant (HR) Poa annua poses a risk to sustainably managing U.S. turfgrass systems, but there is scant knowledge to guide its management. Six focus groups were conducted throughout the United States to gain understanding of socio-economic barriers to adopting herbicide-resistance management practices. Professionals from major turfgrass sectors (golf courses, sports fields, lawn care, and seed/sod production) were recruited as focus-group participants. Discussions emphasized challenges of the weed management of turfgrass systems as compared to agronomic crops. This included greater time constraints for managing weeds and more limited chemical control options. Lack of understanding about the proper use of compounds with different modes of action was identified as a threat to sustainable weed management. There were significant regional differences in perceptions of the existence, geographic scope, and social and ecological causes of HR in managing Poa annua. Effective resistance management will require tailoring chemical and non-chemical practices to the specific conditions of different turfgrass sectors and regions. Some participants thought it would be helpful to have multi-year resistance management programs that are both sector- and species-specific. © 2022 by the authors.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

THE CONSUMER INFORMATION OVERLOAD CONTROVERSY AND PUBLIC POLICY

It is widely believed that providing consumers with more product information produces "overload" and leads to confusion and poorer quality consumer decisions. The existence of a consumer information overload phenomenon has been used by marketers and others to argue against regulations and legislation mandating additional consumer information provision. The belief that a consumer information overload phenomenon exists is based largely on misinterpretations of research findings. The present paper reviews the consumer information overload research literature and concludes that existing research data support the contention that provision of more information, rather than producing overload, actually improves consumer decision making. Implications of the information overload research controversy for consumer policy makers are discussed. Copyright 1983 by The Policy Studies Organization.

Why religion’s burdens are light: From religiosity to implicit self-regulation

To maintain religious standards, individuals must frequently endure aversive or forsake pleasurable experiences. Yet religious individuals on average display higher levels of emotional well-being compared to nonreligious individuals. The present article seeks to resolve this paradox by suggesting that many forms of religion may facilitate a self-regulatory mode that is flexible, efficient, and largely unconscious. In this implicit mode of self-regulation, religious individuals may be able to strive for high standards and simultaneously maintain high emotional well-being. A review of the empirical literature confirmed that religious stimuli and practices foster implicit self-regulation, particularly among individuals who fully internalized their religion's standards. The present work suggests that some seemingly irrational aspects of religion may have important psychological benefits by promoting implicit self-regulation. © 2010 by the Society for Personality and Social Psychology, Inc
