Rubin Observatory is a ground-based astronomical facility under construction, a joint project of the National Science Foundation and the U.S. Department of Energy, designed to conduct a multipurpose 10 yr optical survey of the Southern Hemisphere sky: the Legacy Survey of Space and Time. Significant flexibility in survey strategy remains within the constraints imposed by the core science goals of probing dark energy and dark matter, cataloging the solar system, exploring the transient optical sky, and mapping the Milky Way. The survey’s massive data throughput will be transformational for many other astrophysics domains and Rubin’s data access policy sets the stage for a huge community of potential users. To ensure that the survey science potential is maximized while serving as broad a community as possible, Rubin Observatory has involved the scientific community at large in the process of setting and refining the details of the observing strategy. The motivation, history, and decision-making process of this strategy optimization are detailed in this paper, giving context to the science-driven proposals and recommendations for the survey strategy included in this Focus Issue.Peer reviewedFinal Published versio

Proverbial Modernism: Difficult Literature and the Self-Help Hermeneutic

One point upon which modernism\u27s early advocates and detractors could agree was that it had little useful wisdom to offer. James Joyce even trumpeted his usylessly unreadable Blue Book of Eccles in Finnegans Wake. As a result of this consensus, it seems unlikely to us today that modernist authors could have been implicated in self-help\u27s peddling of popular advice. Few might suspect that Ezra Pound chanted the self-help motto Wake up and Live! every day for forty years, or that, before he wrote How to Win Friends and Influence People, Dale Carnegie yearned to be a modernist, moving to Paris in the 1920s to pen his magnum opus, The Blizzard. Proverbial Modernism argues that we cannot fully understand the stakes of modernist difficulty without considering the concomitant rise of self-help. Conversely, modernism\u27s recalcitrance helps to make visible the neglected complexities of self-help\u27s pragmatic reading method. This dissertation unearths a tradition of mutual critique between the novel and the success manual to illuminate modernism\u27s overlooked embroilment in the practice of reading for advice

Long-Span Cold-Formed Steel Double Channel Portal Frames

A comprehensive study on long-span cold-formed steel portal frames composed of back-to-back channel sections is presented. The aim of the study is to determine appropriate design guidelines in order for engineers to safely and efficiently build larger frames. The system analyzed herein is a haunched portal frame with a knee brace connected between the column and rafter. The objectives of the research were achieved through an extensive experimental study as well as numerical investigations. A comprehensive experimental program was completed to determine the strength and behavior of the frames. A total of nine full scale portal frame systems were tested, eight of which had unbraced columns. Variations to the frame layout, including modifications to the knee connection and the addition of sleeve stiffeners, were tested for both vertical and combined wind and vertical loading conditions. Column base rotational stiffness was quantified in the full scale experiments and in separate component tests. An advanced shell finite element model was created and calibrated with measured material and sections properties and column base stiffness, and was validated with the experimental results. A parametric study was completed to determine the effects of various configurations of the knee brace connection, as well as column base stiffness, on frame ultimate load. A larger span model was created to determine the suitability of the frame design for larger spans. A design procedure was developed to determine frame design loads. An energy method approach was employed to calculate the elastic buckling capacity of the column, which considers the elastic torsional restraint provided by the knee connection. A calibrated beam element model was used to determine the internal actions of the frame. A reliability check was completed and it was determined that the developed design method is suitable to design cold-formed steel portal frames

Recall this Book 38: Beth Blum on Self-Help from Carnegie to Today

Beth Blum, Assistant Professor of English at Harvard, is the author of The Self-Help Compulsion (Columbia University Press 2019). Learn how self-help went from its Victorian roots (worship greatness!) to the ingratiating unctuous style prescribed by the other-directed Dale Carnegie (everyone loves the sound of their own name) before arriving at the "neo-stoical" self-help gurus of today, who preach male and female versions of "stop apologizing!" You'll laugh, you'll cry, you'll either help yourself or learn how to stop caring
