Examining student work for evidence of teacher uptake of educative curriculum materials
(Wiley Periodicals, Inc.Lawrence Erlbaum Associates, 2015-08)
The purpose of this study was to identify evidence in student work of teachers' uptake of educative features in educative curriculum materials. These are features in curriculum materials designed with the specific intent ...
An ecologically-based approach to the design of intercrop agroecosystems: An intercropping system of soybeans and tomatoes in Southern Michigan
(Elsevier, 1984-10)

Benefit cost analysis is seldom applied to programs which aim directly at improving human well-being; the problems in quantifying such benefits, particularly in dollar form, are simply too great. This paper explains ...
Simulation of the potential for life history components to regulate walleye population size
(Elsevier, 1989-02)
A bioenergetic life history simulation model was applied to identify components of the walleye (Stezostedion vitrium) life history that had a potential for population regulation. The model combined a predator-prey model, ...

Contaminant uptake by fish and the potential for transfer to humans modelled over time
(Elsevier, 1986-07)
A model is developed that enables coupling of contaminant uptake with the growth dynamics of fish, exploitation, and transfer and fate. Contaminant concentration in fish is a function of the properties of the contaminant, ...
Quality of life indicators and program evaluation
(Elsevier, 1980)
Social indicators and program evaluation research have much in common. Quality of life work specifically raises the question of objective versus subjective variables, aggregate data versus distributional and individual ...
