This paper examines Canadian federalism's impact on broadband telecommunications infrastructure development in Canada by discussing the limits of the federal telecommunications regulatory sphere in relationship to provincial policy frameworks. I argue that the extensive centralization of federal regulatory powers over telecommunications has not been meaningfully leveraged to promote a national policy approach to telecommunications development. Telecommunications infrastructure development is further frustrated by vastly divergent regulation of right-of-way by provincial regulators and municipalities. As a consequence, telecommunications infrastructure development has become the domain of provincial governments. This paper further considers the emergence of a regime of competitive federalism and province-building through policy experimentation by provincial governments in the absence of meaningful fiscal and collaborative federalism.

In order to cope with the demands of national industrialisation and reconstruction, much attention has been paid in Communist China to public health and medicine in an effort to prevent disease and promote health and thus increase productivity. Since public health practice is closely related to the political system and governmental structure, in addition to indicating actual achievements it serves as an indirect reflection of political and socio-economic conditions in present-day China.

AbstractTwo pilot studies provide insights into the design and operations of biological ion exchange (BIEX) drinking water filters. A lab‐scale pilot with strong‐base anionic (SBA) and weak‐base anionic (WBA) resins demonstrated 35% and 31% removal of dissolved organic carbon (DOC) up to 30 months, until secondary ion exchange exhaustion. While the WBA resins exhibited 14% less removal of DOC, their larger capacity doubled the duration until filter exhaustion. WBA filters were less affected than their SBA counterparts by sulfate‐containing inlet waters. In a second pilot, while water with high DOC yielded rapid exhaustion of SBA resins, air scouring increased the breakup of filter media and improved solids removal by 30× compared to hydraulic backwash alone. Significantly, DOC removal improved by 36% for a week following air scour. Key recommendations include the use of WBA resins to extend operating life while implementing air scouring can dramatically improve short‐term DOC removal.
