Trace Elements in the Hydrologic Cycle of a Tolerant Hardwood Forest Ecosystem

Abstract: The concentrations and annual fluxes of Fe, Al, Mn, Cu and Pb were measured during 1983 in bulk precipitation, throughfall, stemflow, forest floor percolate, mineral soil solution below the root zone and streamflow in a maple-birch stand on an acid podzolic soil at the Turkey Lakes Watershed (TLW), Ontario. Inputs of metals to TLW in precipitation were small in comparison with those in the eastern United States and Europe. Considerable loss of Mn and Cu from the vegetation during both the growing and the dormant (leafless) periods was observed and presumed to be due to leaching. The enrichment in soil solution of all metals examined, in relation to throughfall, was greatest for Al (7X) and least for Cu (1.2X). Aluminum was mobilized in both the forest floor and the mineral soil, the latter possibly in association with SO4 2−. Copper was solubilized in the lower forest floor or the mineral soil. Surface soil contents of Al and Cu were reduced by Al and, to a lesser extent, Cu leaching beyond the effective rooting zone. Iron, Mn and Pb were mobilized largely in the F horizon of the forest floor, most likely by organic acids. Leaching of Fe, Mn and Pb was reduced by metal accumulation in vegetation, the lower forest floor, or mineral soil within the effective rooting zone of the vegetation. Most (80 to 99%) of the metals leached from the rooting zone were retained in the watershed and did not appear in streamwater.

Gaining Access to Late French-Immersion Programs: Class-Based Perspectives of Canadian Students in an Ottawa High School

Abstract: The question of access to French-immersion programs has become a timely subject in Canada as a result of shifting political priorities, cutbacks, and growing concern around finding the most efficient way to teach French as a second language (FSL). While drawing on social selection and identity perspectives on school choice, this article presents the results of a study with a group of Canadian students in an Ottawa high school who had followed a Late French-Immersion (FLI) program in grades seven–eight (ages 11–14). Findings indicate that Canadian-born middle-class parents played an active role in the school choices of their preteens and that students from immigrant and working-class backgrounds were able to compensate for class and cultural disadvantages by playing a leading role in the family decision to accept a LFI placement. Results also showed that students from middle-class families primarily began LFI programs for communication-related purposes; whereas students from working-class backgrounds were ...

IMAGE: a language for the interactive manipulation of a graphics environment

Abstract: This paper addresses itself to the problems involved in programming an interactive computer graphics display. A list of graphical programming facilities considered necessary for an interactive graphic programming language is presented. An examination of several application programs, written in a variety of existing languages, revealed that many of these facilities are usually lacking.This paper presents the design of a new interactive graphics language 'IMAGE', developed specifically to satisfy the above criteria. The language places particular emphasis on providing a graphics application programmer the ability to program graphical interaction. The 'IMAGE' language utilizes the better features of several current graphic languages and combines these features with a unique interaction control structure. This OBJECT / ACTION control structure, the display picture description syntax and the hardware independent handling of input devices are the main features of the language, providing excellent graphical input response and drawing facilities. The device independent input / output structure permits the implementation of a portable language syntax, since there are no references to display hardware devices. All display references are performed through a virtual terminal. This paper contains a detailed description of the main features of the language and these features are illustrated in an example 'IMAGE' program.

Consumption Patterns Among Aging Canadians: A Synthetic Cohort Approach

Abstract: Studies of pre- and post-retirement annual income have focused on the extent to which income falls at this crucial stage in life. Although these studies vary in scope and intent, the overall consensus is that the Canadian retirement income system provides income replacement rates that are in the excess of 60% to 70% for a plurality of Canadians, especially for those who had low incomes during their prime working years. However, little has been published on the extent to which retirees maintain their same levels of consumption. Using data from the Survey of Family Expenditures (FAMEX) and from the Survey of Household Spending (SHS), this study develops a synthetic cohort approach to determine how the consumption patterns of households headed by individuals in their late 40s (in the early 1980s) differ from those of a group of households headed by individuals in their early 70s (in the late 2000s). It finds that, even though the nature of consumption changes over time, the overall levels of consumption “per adult” do not decline by substantial amounts among Canadians as they age.
