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.

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.

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.

In this paper the manufacturing strategies underlying the growing number of Japanese research and development (R&D) laboratories in the United States are examined. In particular, we assess the extent to which Japanese R&D in the United States is consistent with a model of global localization. The analysis is based upon data collected by a mailed questionnaire survey and through interviews with the directors of Japanese R&D laboratories. In its basic form, global localization is a manufacturing strategy that seeks to promote the emergence of an integrated manufacturing complex and attendant technology-development capability within North America and other major markets. In the case of Japanese automobile firms, close ties are observed between R&D and production facilities in the United States. In computers, electronics, and other industries, however, the principal linkage of R&D laboratories in the United States is to R&D laboratories in Japan. Divisional R&D laboratories in Japan remain the anchor for emerging international technology-development networks.
