An overdose of a common over-the-counter sodium phosphate enema solution was fatal in an infant. The marked hypernatremia, acidemia, hyperphosphatemia, and hypocalcemia observed before death were also produced in a porcine model. A study using pigs showed that the enema solution was lethal if retained in doses above 20 mL/kg, equivalent to four pediatric-sized enemas in a 2-year-old child. Even normal doses of the enema solution caused measurable changes in serum phosphorus and calcium levels.

This article documents the design and pilot delivery of a computermediated, competency-based child welfare practice course founded on constructivist instructional principles. It was created in 2003 as part of the University of Northern British Columbia (UNBC) Social Work program's child welfare specialization stream. Offered to learners via the internet using web-based tools and resources, the course expanded access to the child welfare specialization option for social work students studying at UNBC's three rural regional campuses. The article examines emerging teaching and learning options across four components of online course development and delivery. The background of the specialization stream in the social work program is reviewed, constructivist instructional design theory is summarized, and a rationale for adopting this approach is discussed. This is followed by a brief report on the findings of the formative evaluation of the pilot delivery. Finally, the evolving underpinnings of online instruction are considered, including shifts in the roles of learners and instructors and the role of pedagogy in an evolving educational paradigm.

Additional index words. Fragaria 3ananassa, fruit breeding, short-day, June-bearing, processing 'Charm' is a new June-bearing (short-day) strawberry (Fragaria •ananassa Duchesne ex Rozier) cultivar from the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) breeding program in Corvallis, OR, released in cooperation with the Oregon Agricultural Experiment Station and the Washington State University Agricultural Research Center. 'Charm' is a high-yielding cultivar that produces medium-large sized, easily capped fruit with excellent fruit quality that are particularly suited to ice cream formulations. A U.S. plant patent application (S.N. 13/694,975) has been submitted. Origin'Charm' was selected in 2001 from the cross BC 92-14-31 • WA 94023-1 made in 1999 and was tested as ORUS 2262-2 (Fig. 1). BC 92-14-31 [BC 86-24-107 (Providence • Sumas) • Nanaimo] was an advanced selection in the Agriculture and Agri-Food Canada breeding program and WA 94023-1 (ORUS 1083-135 • NJ 8713-8) was a selection made in Oregon from a cross made by P. Moore with the Washington State University program (Puyallup). The purpose of the cross was to combine the extremely firm and darkcolored fruit of BC 92-14-31 with the overall good characteristics of WA 94023-1 to improve the latter's firmness and light color. The pedigree represents a mix of genotypes developed in the Pacific Northwest (United States and Canada) and the United Kingdom.
