This article proposes a Python-based Amtrak and Weather Underground (PAWU) tool to collect data on Amtrak (the main passenger train operator in the United States) departure and arrival times with weather information. In addition, this article offers a database, developed with PAWU, of the operating characteristics of 16 Amtrak routes from 2008 to 2019. More specifically, PAWU enables users to retrieve Amtrak departure and arrival times of any train number throughout the United States. It then automatically retrieves weather information from Weather Underground for each rail station and stores the data collected in a local MySQL database. Users can easily select any desired train number(s) and date range(s) without dealing with the code and the raw data from those sources that are in different formats. The database itself can be used, in part, to develop, apply, and benchmark models that assess the performance of rail services such as the one offered by Amtrak.

Through the Louisiana Purchase in 1803, the United States expanded its size by over 800,000 square miles. But neither President Thomas Jefferson nor Congress knew exactly what they had bought until 1806, when Meriwether Lewis and William Clark returned from their famous expedition. One of the most significant contributions of the Expedition was a better perception of the geography of the Northwest. Lewis and Clark prepared approximately 140 maps and filled in the main outlines of the previously blank map of the northwestern United States. Robert I. Field has done much the same for the vast territory of U.S. health care regulation.On the front cover of Fields new book, Health Care Regulation in America: Complexity, Confrontation, and Compromise, is a picture of a giant three-dimensional labyrinth. Rarely is cover art so perfectly appropriate.

AbstractThe Early Triassic vertebrate record from low paleolatitudes is spotty, which led to the notion of an ‘equatorial vertebrate eclipse’ during the Smithian. Here we present articulated ray-finned fishes (Actinopterygii), collected from the marine Lower Triassic Thaynes Group at three new localities in Elko County (Nevada, USA), which were deposited within the equatorial zone. From the Smithian of the Winecup Ranch, we describe two partial skulls of the predatory actinopterygianBirgeria(Birgeriidae), attributed toB.americananew species andBirgeriasp.Birgeria americanan. sp. is distinguished from other species by a less reduced operculogular series. With an estimated total length of 1.72–1.85m, it is among the largest birgeriids. We confirm thatBirgeriaencompasses species with either two or three rows of teeth on the maxilla and dentary, and suggest that species with three well-developed rows are restricted to the Early Triassic. From the latest Smithian of Palomino Ridge, we present a three-dimensional, partial skull of the longirostrine predatorSaurichthys(Saurichthyidae). This and other occurrences indicate that saurichthyids were common in the western USA basin. From the early late Spathian of Crittenden Springs, we describe a posterior body portion (Actinopterygii indet.). This find is important given the paucity of Spathian osteichthyan sites. We provide a summary of Early Triassic vertebrate occurrences in the United States, concluding that vertebrate fossils remain largely unstudied. The presence of predatory vertebrates in subequatorial latitudes during the Smithian confirms that Early Triassic trophic chains were not shortened and contradicts the ‘equatorial vertebrate eclipse’.

An examination is made of the trends toward new forms of industrial democracy in three liberal capitalist societies: France, the United States and Australia. A three-dimensional framework is introduced which uses the ideology of the labour movement, the degree of control which is sought by employees at the enterprise level and the level at which participation occurs, to compare developments in each country. It is argued that a convergence of approaches is occurring in these countries towards the participatory enterprise, albeit with some variations, within the framework of liberal capitalism.
