Federal assistance to public transportation is provided primarily through the public transportation program administered by the Department of Transportation's Federal Transit Administration (FTA). The federal public transportation program was authorized from FY2016 through FY2020 as part of the Fixing America's Surface Transportation (FAST) Act. Chapter 1 provides an introduction to the program as authorized by the FAST Act. Unless legislative action is taken, formula funding for the federal transit program could be decreased by approximately $1 billion in FY2020, roughly 12% from the amount authorized in the FAST Act as reported in chapter 2. Almost every conversation about surface transportation finance begins with a two-part question: What are the "needs" of the national transportation system, and how does the nation pay for them? Chapter 3 is aimed at discussing the "how to pay for them" question. The 116th Congress is expected to address surface transportation reauthorization, including consideration of how to deal with the persistent gap between projected HTF revenues and program costs as discussed in chapter 4 and 5. Chapter 6 begins by discussing FHWA assistance for the repair and reconstruction of highways and bridges damaged by disasters (such as the 2017 Hurricanes Harvey, Irma, and Maria) or catastrophic failures (such as the collapse of the Skagit River Bridge in Washington State in 2013). This is followed by a discussion of FTA's assistance program, established in 2012, which has provided assistance to public transportation systems on two occasions, once after Hurricane Sandy in 2012 and again after the 2017 hurricanes. The focus of chapter 7 is how best to implement and finance a system of deterrence, protection, and response that effectively reduces the possibility and consequences of terrorist attacks without unduly interfering with travel, commerce, and civil liberties. The focus of chapter 8 is on truck freight and that portion of the rail and port industries that transports truck trailers and containers (intermodal freight). The Transportation Infrastructure Finance and Innovation Act (TIFIA) program provides long-term, low-interest loans and other types of credit assistance for the construction of surface transportation projects as reported in chapter 9. DOT opened the Build America Bureau in July 2016. Chapter 10 assesses, progress DOT made to establish the Bureau and carry out its responsibilities, the Bureau's process for evaluating applications, and whether the Bureau provided a clear rationale for decisions in that process. Chapter 11 examines the implications for federal transit policy of the current weakness and possible future changes in transit ridership. Chapter 12 discusses the extent to which information exists about future transit workforce needs and FTA assists with addressing current and future transit workforce needs.

This collection of articles deals with the benefits of different types of stem cells sources, use, manipulation, and aspects for the treatment of chronic diseases. Topics include the role of calcium channel pathway/s in the regulation of neural stem cell differentiation; the evolutionary roles of the totipotent, pluripotent, or even multipotent stem cells; the derivations of multipotent MSCs; and potential canine-derived stem cell therapies for dogs. The scope of the book also provokes further studies into other topics, such as MSC differentiation into hepatocytes and the involvement of these cells with microRNA-133 in type 1 diabetes; the role of Vitronectin in the differentiation into endoderm; the extent to which the stemness of dental pulp stem cells might be useful; PBMCs as a source for pluripotent stem cells; yoga in possible synergy with the finding that bone marrow stromal cells provide relief from a laboratory reagent used as drug-mediated pain in spinal cord injury.

This book analyzes Liberia's transport connectivity and identifies existing bottlenecks and possible growth potentials, using spatial techniques and data, including the first-ever georeferenced detailed road network data in Liberia.

Long-term economic growth and increasing vehicle congestion is creating a greater demand for efficient and safe transportation. The high cost of maintaining and fixing pre-existing infrastructure is leading the industry to realize that sustainable long-term transportation planning is needed to keep pace with the growing economy. Building a Sustainable Transportation Infrastructure for Long-Term Economic Growth examines contemporary transportation issues through the lens of various modes of transportation while also focusing on the importance of sustainability, urban planning, and funding. The book covers the topics of sustainability and climate change, public management and planning, financing of transportation infrastructure, and revenue and spending issues facing modern transportation infrastructure. It is ideally designed for engineers, planners, government officials, transportation specialists, legislators, researchers, academicians, students, and industry professionals seeking current research on sustainable transport systems.
