America and the Canadian Presence: As the United States Faces Global Challenges,How Does Canada Fit In? 1

On the occasion of the 40th anniversary of the Center for Canadian–American Studies at Western Washington University, the author considers the trends that will shape US–Canadian relations over the next 40 years. Specifically the author considers the deepening of continental economic integration; the consequences of reaching the limits of current governance of integration and the coming need to negotiate new arrangements and institutions to manage the shared economy; the importance of an anticipated drive for greater public sector productivity in both countries at the federal and state/provincial levels; and the implications of a generational transition in the management of the relationship from the Baby Boomers to a younger generation with an attendant need to maintain the best traditions of amicable bilateral relations while evolving and adapting the management of the relationship in keeping with changing times and new challenges. For each of these changes, it is to be hoped that education in Canadian studies will be available for future leaders in the public and private sectors.     

Some middle and late Cambrian trilobites and brachiopods from the Adamsfield Trough,Tasmania

Jago, J.B., Bentley, C.J., Laurie, J.R. &; Corbett, K.B., 26 June 2018. Some middle and late Cambrian trilobites and brachiopods from the Adamsfield Trough, Tasmania. Alcheringa 43, 1-17. ISSN 0311-5518.

Cambrian Series 3 and Furongian trilobites and brachiopods are described from the Adamsfield Trough in southwestern Tasmania. The oldest fossils are very poorly preserved trilobites, assigned to Asaphiscidae gen. et sp. indet. from within the Island Road Formation a short distance above the unconformity with the underlying Proterozoic Wedge River Beds. A trilobite species from within the isolated Boyd River Formation is referred to Lioparia sp. The Island Road Formation and the Boyd River Formation are stratigraphically equivalent to the Trial Ridge Beds which have previously been dated as belonging to the Lejopyge laevigata Zone. The Trial Ridge Beds are overlain unconformably by the Singing Creek Formation. In the Adamsfield, Clear Hill and Stepped Hills areas, stratigraphic equivalents of the Singing Creek Formation collectively contain the trilobites Pseudaphelaspis sp., Pseudaphelaspis? sp., Prochuangia sp., Mindycrusta sp., Nepeidae gen. et sp. indet., and Olenidae gen. et sp. indet. plus the brachiopods described herein as Billingsella sp. aff. costata, Billingsella sp. A, Billingsella sp. B and a possible member of the Billingselloidea. The Singing Creek Formation has been previously correlated with the Stigmatoa diloma Zone. The genus Lotosoides Shergold 1975 is placed in synonymy with Prochuangia Kobayashi 1935.
