Collection Development of HIV/AIDS Information Resources in American Libraries
HIV/AIDS remains an incurable epidemic in the United States that disproportionately affects men who have sex with men (MSM) and African Americans. Library and information science (LIS) professionals can play a vital role in keeping these higher risk groups informed about preventing HIV/AIDS and living with the disease, through a variety of current information resources that addresses their specific questions. This paper reviews collection development policies proposed by LIS professionals and library agencies since the late 1980s, and evaluates how such policies took higher-risk user groups into consideration. The findings of this paper are that collection development policies have become more attentive to higher-risk user groups but that LIS research trends are now beginning to focus more on the HIV/AIDS epidemic in developing countries, which is to the detriment of Americans who still need up-to-date materials on the disease
Restoration versus Demolition: Case History of Amsterdam, New York
The purpose of this study is to disclose why Amsterdam, New York -- like thousands of other cities in the United States -- has shunned restoration. It is hoped these findings will prove the worth of the ordinary old buildings and that the revitalization of the urban fabric does not follow from demolition and newness
Project Labyrinth: Exploration of Modulating Guitar Signals
The overall objective of this project is to create a guitar pre-amplifier in the casing of an effects pedal. The pedal must be able to modulate amplitude and pitch. More specifically, the design for this pedal will include floating frequency filtering, phase shifting, and amplitude modulation
Py-Tetrad and RPy-Tetrad: A New Python Interface with R Support for Tetrad Causal Search
We give novel Python and R interfaces for the (Java) Tetrad project for
causal modeling, search, and estimation. The Tetrad project is a mainstay in
the literature, having been under consistent development for over 30 years.
Some of its algorithms are now classics, like PC and FCI; others are recent
developments. It is increasingly the case, however, that researchers need to
access the underlying Java code from Python or R. Existing methods for doing
this are inadequate. We provide new, up-to-date methods using the JPype
Python-Java interface and the Reticulate Python-R interface, directly solving
these issues. With the addition of some simple tools and the provision of
working examples for both Python and R, using JPype and Reticulate to interface
Python and R with Tetrad is straightforward and intuitive.Comment: Causal Analysis Workshop Series (CAWS) 2023, 12 pages, 4 Figures, 2

Inverting the Hopf map
We calculate the η-localization of the motivic stable homotopy ring over C, confirming a conjecture of Guillou and Isaksen. Our approach is via the motivic Adams-Novikov spectral sequence. In fact, work of Hu, Kriz and Ormsby implies that it suffices to compute the corresponding localization of the classical Adams-Novikov E₂-term, and this is what we do. Guillou and Isaksen also propose a pattern of differentials in the localized motivic classical Adams spectral sequence, which we verify using a method first explored by Novikov
