State Defense

The US Department of Defense (DoD) makes extensive use of the US multimodal transportation network to move material for operational support, keep facilities supplied, and move personnel. Federal agencies, especially the US Department of Transportation, work closely with the DoD. States and localities also play a critical role in defense infrastructure. This research examines state freight and defense community plans to identify how the transportation needs of the DoD are being addressed in state planning. The findings are 72% of the 50 state freight plans mention defense transportation, while 34% considered defense transportation needs in-depth. About 6 of 19 identified state defense community plans mention transportation, but only 3 have specific defense transportation goals. Nationally, the DoD and federal agencies work closely together to maintain the nation’s defense transportation network, but at the local and state level closer cooperation on transportation issues should be developed. Military readiness remains high, but efficiencies in the system can be improved.

AbstractTransportation of livestock carries the risk of spreading foreign animal diseases, leading to costly public and private sector expenditures on disease containment and eradication. Livestock movement tracing systems in Europe, Australia and Japan have allowed epidemiologists to model the risks engendered by transportation of live animals and prepare responses designed to protect the livestock industry. Within the US, data on livestock movement is not sufficient for direct parameterization of models for disease spread, but network models that assimilate limited data provide a path forward in model development to inform preparedness for disease outbreaks in the US. Here, we develop a novel data stream, the information publicly reported by US livestock markets on the origin of cattle consigned at live auctions, and demonstrate the potential for estimating a national-scale network model of cattle movement. By aggregating auction reports generated weekly at markets in several states, including some archived reports spanning several years, we obtain a market-oriented sample of edges from the dynamic cattle transportation network in the US. We first propose a sampling framework that allows inference about shipments originating from operations not explicitly sampled and consigned at non-reporting livestock markets in the US, and we report key predictors that are influential in extrapolating beyond our opportunistic sample. As a demonstration of the utility gained from the data and fitted parameters, we model the critical role of market biosecurity procedures in the context of a spatially homogeneous but temporally dynamic representation of cattle movements following an introduction of a foreign animal disease. We conclude that auction market data fills critical gaps in our ability to model intrastate cattle movement for infectious disease dynamics, particularly with an ability to addresses the capacity of markets to amplify or control a livestock disease outbreak.Author SummaryWe have automated the collection of previously unavailable cattle movement data, allowing us to aggregate details on the origins of cattle sold at live-auction markets in the US. Using our novel dataset, we demonstrate potential to infer a complete dynamic transportation network that would drive disease transmission in models of potential US livestock epidemics.

Building America: The Life of Benjamin Henry Latrobe is a biography of America’s first professionally trained architect and engineer. Born in 1764, Latrobe was raised in Moravian communities in England and Germany. His parents expected him to follow his father and brother into the ministry, but he rebelled against the church. Moved to London, he studied architecture and engineering. In 1795 he emigrated to the United States and became part of the period’s Transatlantic Exchange. Latrobe soon was famous for his neoclassical architecture, designing important buildings, including the US Capitol and Baltimore Basilica as well as private homes. Carpenters and millwrights who built structures more cheaply and less permanently than Latrobe challenged his efforts to establish architecture as a profession. Rarely during his twenty-five years in the United States was he financially secure, and when he was, he speculated on risky ventures that lost money. He declared bankruptcy in 1817 and moved to New Orleans, the sixth American city that he lived in, hoping to recoup his finances by installing a municipal water system. He died there of yellow fever in 1820. The themes that emerge in this biography are the critical role Latrobe played in the culture of the early republic through his buildings and his genius in neoclassical design. Like the nation’s political founders, Latrobe was committed to creating an exceptional nation, expressed in his case by buildings and internal improvements. Additionally, given the extensive primary sources available for this biography, an examination of his life reveals early American attitudes toward class, family, and religion.

Over Time

In this study, we explore the long-term trends of floodplain population dynamics at different spatial scales in the contiguous United States (U.S.). We exploit different types of datasets from 1790–2010—i.e., decadal spatial distribution for the population density in the US, global floodplains dataset, large-scale data of flood occurrence and damage, and structural and nonstructural flood protection measures for the US. At the national level, we found that the population initially settled down within the floodplains and then spread across its territory over time. At the state level, we observed that flood damages and national protection measures might have contributed to a learning effect, which in turn, shaped the floodplain population dynamics over time. Finally, at the county level, other socio-economic factors such as local flood insurances, economic activities, and socio-political context may predominantly influence the dynamics. Our study shows that different influencing factors affect floodplain population dynamics at different spatial scales. These facts are crucial for a reliable development and implementation of flood risk management planning.

We utilize functional data analysis techniques to investigate patterns of COVID-19 positivity and mortality in the US and their associations with Google search trends for COVID-19-related symptoms. Specifically, we represent state-level time series data for COVID-19 and Google search trends for symptoms as smoothed functional curves. Given these functional data, we explore the modes of variation in the data using functional principal component analysis (FPCA). We also apply functional clustering analysis to identify patterns of COVID-19 confirmed case and death trajectories across the US. Moreover, we quantify the associations between Google COVID-19 search trends for symptoms and COVID-19 confirmed case and death trajectories using dynamic correlation. Finally, we examine the dynamics of correlations for the top nine Google search trends of symptoms commonly associated with COVID-19 confirmed case and death trajectories. Our results reveal and characterize distinct patterns for COVID-19 spread and mortality across the US. The dynamics of these correlations suggest the feasibility of using Google queries to forecast COVID-19 cases and mortality for up to three weeks in advance. Our results and analysis framework set the stage for the development of predictive models for forecasting COVID-19 confirmed cases and deaths using historical data and Google search trends for nine symptoms associated with both outcomes.

New Procedures

Alternative girth weld defect acceptance criteria implemented in major international codes and standards vary significantly. The requirements for welding procedure qualification and the allowable defect size are often very different among the codes and standards. The assessment procedures in some of the codes and standards are more adaptive to modern micro-alloyed TMCP steels, while others are much less so as they are empirical correlations of test data available at the time of the standards creation. A major effort funded jointly by the US Department of Transportation and PRCI has produced a comprehensive update to the girth weld defect acceptance criteria. The newly proposed procedures have two options. Option 1 is given in an easy-to-use graphical format. The determination of allowable flaw size is extremely simple. Option 2 provides more flexibility and generally allows larger flaws than Option 1, at the expense of more complex computations. Option 1 also has higher fracture toughness requirements than Option 2, as it is built on the concept of plastic collapse. In comparison to some existing codes and standards, the new procedures (1) provide more consistent level of conservatism, (2) include both plastic collapse and fracture criteria, and (3) give necessary considerations to the most frequently occurring defects in modern pipeline constructions. This paper provides an overview of the technical basis of the new procedures and validation against experimental test data.

Barriers To Change

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study explores bureaucratic organization and innovation in U.S. state department of transportation (DOT) websites. To determine if working with third parties fosters change in state DOT websites, it employs a two-part, explanatory sequential mixed-methods design. In phase one, an online survey was disseminated to IT managers and communications officers in all 50 states to collect data regarding agency demographics, bureaucratic models, and Web infrastructure. In total, 45 valid responses (or 90 percent) were received from DOTs indicating that most built, hosted, and managed their websites in-house, but that state-level IT consolidations required many to pool resources with third parties. In research phase two, 12 semi-structured interviews were conducted of a maximum variation sample of survey respondents. These interviews were conducted to explain why DOTs built and operated their websites with the support of third parties. Employing a grounded theoretical approach, analysis revealed 6 themes explaining website adoption and showed that working with third parties can foster innovation; however, not all change is positive. Therefore, a need exists for governments to selectively work with others, ascertain future barriers to change, and ensure that adopted innovations meet desired ends. Finally, five best practices informed by study findings are presented that may help decision-makers and civil servants provide e-government services in a flexible manner.

This paper is based mainly on a study carried out in 1976/7 for the UK Department of Industry into the long-term development of air traffic control systems in Europe by a team drawn from the Civil Aviation Authority, the Royal Signals and Radar Establishment and private industry, in which Coopers and Lybrand provided the economic expertise.Until the early 1970s, air traffic control was almost completely neglected by air transport economists. Economists contributed to the planning of airports and airline operations but not to the third facet of the air transport system. However, in 1970–1, in conjunction with a programme of expansion and improvement of the country's airports and airways, the US Department of Transportation launched a major study of the airport and airways system. This was designed to establish an equitable charging policy between the different categories of user but in the event its recommendations in this area have only recently begun to be followed.
