A clinical decision tree was developed using point-of-care characteristics to identify patients with culture-proven sepsis due to extended-spectrum β-lactamase–producing Enterobacterales (ESBL-PE). We compared its performance with the clinical gestalt of emergency department (ED) clinicians and hospital-based clinicians. The developed tree outperformed ED-based clinicians but was comparable to inpatient-based clinicians.

To investigate the manipulation of electromagnetic properties of two-dimensional materials, this effort characterizes charge transfer behavior of colloidal COF-5 (covalent organic framework) in the presence of various metal ions. A series of metal chloride compounds was introduced to COF-5 in solution and solid film phases and the interaction of the material with electromagnetic radiation was monitored across the visible region using electronic absorption spectroscopy. Notable changes were observed, quantified, and discussed for copper (II) chloride (CuCl2), chromium (III) chloride (CrCl3), and iron (III) chloride (FeCl3) with COF-5. Ligand-to-metal and metal-to-ligand charge transfer are explored as a possible mechanism for the observed electronic behaviors.

In the 1990s, policymakers at Yellowstone and Banff National Parks enacted two of the most controversial programs in the history of protected lands. At Yellowstone, the U.S. National Park Service (nps) and the U.S. Fish and Wildlife Service (fws) personnel reintroduced wolves into the Yellowstone ecosystem. This program restored a crucial element to the park ecosystem that had been eliminated decades before and not returned since extermination. At Banff, federal authorities imposed strict limits to growth of the town of Banff. This action reversed a policy dating to the park's establishment in the late nineteenth century of allowing and encouraging growth and development of the town within Banff. How did these policy changes occur?

Does the type of policy being considered determine the politics surrounding it? In this article, I examine how policy reversals may produce different politics than initial policy adoptions in the context of state river management policy. Traditionally, dam building was the dominant management policy, but in recent decades, efforts to restore rivers to their natural conditions through the removal of dams have become more prominent. I find that the patterns of state policymaking for policy reversals are generally similar to those that have been documented for policy adoptions, but with some important differences. Diffusion of reversals involves more states outside of active regions than is seen typically with policy adoption, and reversal diffusion occurs more gradually than adoption diffusion with many policy innovations. Finally, the most important determinants of these state policy reversals are a state's fiscal health and the presence of relevant interest groups.
