A program was developed using a genetic algorithm and automated lookup features to design an efficient passenger rail system for the eastern-half of the United States connecting large cities, metropolitan populations greater than two million, with overnight rail service. The results of the program predicted a passenger starting at the farthest point of the system boards the train at 16:02 on average and arrives at a different point of the system at 07:57 on average the following day, assuming the train travels an average speed of 70 mph. The design used actual distances by train track where possible. The system was modeled with six trains that meet at a hub and exchange passengers and continue on to their destination. The optimal solution had a total one-way minimum distance of 4334 km (2693 miles). Assuming the same ridership that currently exists on a popular train route, ticket prices would average $62 (USD) for a one-way ticket. For this system to be feasible, the government would need to own or lease one set of tracks for all the routes determined, build a hub for passengers to transfer trains near Charleston, WV, and ensure the trains are unimpeded by other trains. Installing tracks that go around cities that the trains do not stop at would be a great benefit also. With advances in communication, GPS, and train control technology, this article points out the benefits of publically available tracks to form a transportation network similar to that found in road, air, and water traffic.

The vision for high-speed rail in America includes corridors that are “emerging” as candidates for investment in passenger rail service improvements including increasing maximum authorized speeds to 90 and 110 mph. Will increasing speeds up to 110 mph be cost effective in terms of attracting new riders? This paper will explore the results of studies examining incremental capital costs and the marginal ridership and revenue increases in the Richmond – Hampton Roads passenger rail project and other current emerging high-speed rail corridors throughout the United States.

The New Deal

El artículo analiza la diplomacia pública del gobierno de Lázaro Cárdenas centrándose en su opción por publicitar la pobreza nacional en el extranjero, especialmente en Estados Unidos. Se plantea que se trató de una estrategia inédita, que accedió a poner en riesgo el “prestigio nacional” con el fin de justificar ante la opinión pública estadounidense la necesidad de implementar las reformas contenidas en el Plan Sexenal. Aprovechando la inusual empatía hacia los pobres en tiempos del New Deal, se construyó una imagen específica de pobreza que fuera higiénica y redimible. Ésta, sin embargo, no generó consenso entre los mexicanos. This article analyzes the public diplomacy of the government of Lázaro Cárdenas, focusing on the administration’s decision to publicize the nation’s poverty internationally, especially in the United States. This study suggests that this was an unprecedented strategy, putting “national prestige” at risk in order to explain the importance of implementing the reforms contained in the Six Year Plan, in the face of public opinion in the United States. Taking advantage of the increased empathy felt towards the poor during the New Deal, a specific image of hygienic and redeemable poverty was constructed. However, this strategy did not generate agreement among Mexicans.

Trump Administration

Lawyers played a key role in challenging the Trump administration’s Travel Ban on entry into the United States of nationals from various majority-Muslim nations. Responding to calls from nongovernmental organizations (NGOs), which were amplified by social media, lawyers responded to the Travel Ban’s chaotic rollout by providing assistance to foreign travelers at airports. Their efforts led to initial court victories, which in turn led the government to soften the Ban somewhat in two superseding executive actions. The lawyers’ work also contributed to the broader resistance to the Trump administration by dramatizing its bigotry, callousness, cruelty, and lawlessness. The efficacy of the lawyers’ resistance to the Travel Ban shows that, contrary to strong claims about the limits of court action, litigation can promote social change. General lessons about lawyer activism in ordinary times are difficult to draw, however, because of the extraordinary threat Trump poses to civil rights and the rule of law.

Ethical Response

Every year, hundreds of U.S. citizens patrol the Mexican border dressed in camouflage and armed with pistols and assault rifles. Unsanctioned by the government, these militias aim to stop the movement of narcotics into the United States. Recent interest in the anthropology of ethics has focused on how individuals cultivate themselves toward a notion of the ethical. In contrast, within the militias, ethical self-cultivation was absent. I argue the volunteers derived the power to be ethical from the control of the dominant moral assemblage and the construction of an immoral “Other” which provided them the power to define a moral landscape that limited the potential for ethical conflicts. In the article, I discuss two instances Border Watch and its volunteers dismissed disruptions to their moral certainty and confirmed to themselves that their actions were not only the “right” thing to do, but the only ethical response available.

The Status

This article describes the approach, methods, and findings of a quantitative analysis of the seismic vulnerability in low-to-moderate seismic hazard regions of the Central and Eastern United States for system-wide assessment of typical multiple span bridges built in the 1950s through the 1960s. There is no national database on the status of seismic vulnerability of bridges, and thus no means to estimate the system-wide damage and retrofit costs for bridges. The study involved 380 nonlinear analyses using actual time-history records matched to four representative low-to-medium hazard target spectra corresponding with peak ground accelerations from approximately 0.06 to 0.3 g. Ground motions were obtained from soft and stiff site seismic classification locations and applied to models of four typical multiple-girder with concrete bent bridges. Multiple-girder bridges are the largest single category, comprising 55% of all multiple span bridges in the United States. Aging and deterioration effects were accounted for using reduced cross-sections representing fully spalled conditions and compared with pristine condition results. The research results indicate that there is an overall low likelihood of significant seismic damage to these typical bridges in such regions, with the caveat that certain bridge features such as more extensive deterioration, large skews, and varied bent heights require bridge-specific analysis. The analysis also excludes potential damage resulting from liquefaction, flow-spreading, or abutment slumping due to weak foundation or abutment soils.

ABSTRACTIn the United States, civil common carrier telecommunications are provided by private companies, not by any agency of the government. Regulation of these services and spectrum management oversight is provided by the Federal Communications Commission (FCC), an agency of the government. Government telecommunications are operated by individual agencies, e.g. the Department of Defense, under the overall regulation of the Office of Spectrum Management of the National Telecommunications and Information Administration (NTIA), a government body separate from the FCC. In bands shared by the civil and government sectors, liaison and coordination is effected between the FCC and the NTIA.

This study analyzes securitized discourses and counter narratives that surround the COVID-19 pandemic. Controversial cases of security related political communication, salient media enunciations, and social media reframing are explored through the theoretical lenses of securitization and cascading activation of framing in the contexts of Slovakia, Russia, and the United States. The first research question explores whether and how the frame element of moral evaluation factors into the conversations on the securitization of the pandemic. The analysis tracks the framing process through elite, media, and public levels of communication. The second research question focused on fairly controversial actors— “rogue actors” —such as individuals linked to far-leaning political factions or militias. The proliferation of digital media provides various actors with opportunities to join publicly visible conversations. The analysis demonstrates that the widely differing national contexts offer different trends and degrees in securitization of the pandemic during spring and summer of 2020. The studied rogue actors usually have something to say about the pandemic, and frequently make some reframing attempts based on idiosyncratic evaluations of how normatively appropriate is their government's “war” on COVID-19. In Slovakia, the rogue elite actors at first failed to have an impact but eventually managed to partially contest the dominant frame. Powerful Russian media influencers enjoy some conspiracy theories but prudently avoid direct challenges to the government's frame, and so far only marginal rogue actors openly advance dissenting frames. The polarized political and media environment in the US has shown to create a particularly fertile ground for rogue grassroots movements that utilize online platforms and social media, at times going as far as encouragement of violent acts to oppose the government and its pandemic response policy.
