Transportation Technology Center, Inc (TTCI) reviewed rail transit track inspection and maintenance standards in North America. These agency standards were benchmarked against similar protocols existing in other parts of the world. In addition, transit agencies were surveyed to document inspection, maintenance, and operating practices to understand variations in inspection and maintenance standards. Approximately 30 agencies participated in the survey which establishes a significant representative sample of North American transit operations. An analysis of track-related accidents was conducted to determine where changes might be required to existing standards and/or where potential gaps may exist. From this analysis, a prioritized list of recommendations was developed. The list consists of items that can be implemented immediately and also items requiring additional research and development. This research is part of the Federal Transit Administration (FTA) and Center for Urban Transportation Research (CUTR) standards development program. The program is intended to improve the safety and efficiency of rail transit operations.

Expanding world economic prosperity and probable peaking of conventional petroleum production in the coming decades requires efforts to increase the efficiency of, and the development of alternatives to, petroleum-based fuels used in automotive transportation. North America has been aggressively pursuing both approaches for over ten years. Mainly as a result of lower prices due to global sourcing, magnesium has recently emerged as a serious candidate for lightweighting, and thus increasing the fuel efficiency of, automotive transportation. Automotive vehicles produced in North America currently use more Mg than vehicles produced elsewhere in the world, but the amounts per vehicle are very small in comparison to other materials such as steel, aluminum and plastics. The reasons, besides price, are primarily a less-developed state of technology for Mg in automotive transportation applications and lack of familiarity by the vehicle manufacturers with the material. This paper reviews some publicly-known, recent, present and future North American research and development activities in Mg for automotive applications.

Human Factors Research

Human factors research in urban transportation has been done in bus systems, personal rapid transit (PRT), demand-responsive systems, rail transit, and to a very limited extent in modal choice. The last in particular needs more investigation, which might concentrate on the motivational variables affecting decisions whether to go by private car or by bus (or other system). Various research projects were described in the Human Factors Workshop at the last meeting of the Transportation Research Board.

Many factors influence where U.S. tech multinational corporations decide to conduct their global artificial intelligence research and development (R&D). Company AI labs are spread all over the world, especially in North America, Europe and Asia. But in contrast to AI labs, most company AI staff remain concentrated in the United States. Roxanne Heston and Remco Zwetsloot explain where these companies conduct AI R&D, why they select particular locations, and how they establish their presence there. The report is accompanied by a new open-source dataset of more than 60 AI R&D labs run by these companies worldwide.

The world market for desiccated coconut (DC) is examined within a supply and demand framework. Production and marketing arrange­ments within DC producing countries are analysed, in addition to consumption trends in the major DC markets of Europe and North America. The prospects for expanding the DC market are then considered, and some potential is found in amas such as: research and development, product promotion and‑markethig strategy.

 The 4-H Citizenship Project offers the opportunity to help 4-H members relate all of their 4-H projects and experiences to the world around them. The 4-H Citizenship manuals will serve as a guide for 4-H Citizenship experiences. To be truly meaningful to the real-life needs and interests of your group, the contribution of volunteer leaders is essential. Each person, neighborhood, and community has individual needs that you can help your group identify. This 14-page major revision of Unit IV covers the heritage project. Written by John Rutledge, Joy C. Jordan, and Dale Pracht and published by the UF/IFAS Extension 4-H Youth Development program. https://edis.ifas.ufl.edu/4h019

Every child has a right to an education. In the United States, the issue is not necessarily about access to a school but access to a quality education. With strict compulsory education laws, more than 50 million students enrolled in primary and secondary schools, and billions of dollars spent annually on public and private education, American children surely have access to buildings and classrooms. However, because of a complex and competitive system of shared policymaking among national, state, and local governments, not all schools are created equal nor are equal education opportunities available for the poor, minorities, and underprivileged. One manifestation of this inequity is the lack of qualified teachers in many urban and rural schools to teach certain subjects such as science, mathematics, and technology. The purpose of this article is to describe a partnership model between two major institutions (The American Museum of Natural History and The City University of New York) and the program designed to improve the way teachers are trained and children are taught and introduced to the world of science. These two institutions have partnered on various projects over the years to expand educational opportunity especially in the teaching of science. One of the more successful projects is Seminars on Science (SoS), an online teacher education and professional development program, that connects teachers across the United States and around the world to cutting-edge research and provides them with powerful classroom resources. This article provides the institutional perspectives, the challenges and the strategies that fostered this partnership.
