2 McDaniel, SusanAdoption in Canada: A neglected area of data collection and researchFor some decades there has been in Canada, as in the United States, recurrent public interest in adoption. At various times this interest has been kindled by professional concern about unauthorized child placement and by the plight of children made homeless by war and other calamities. More recently...Canada; Adoption; Statistics1981
3 Hawkes, KristenAlyawara plant use and optimal foraging theoryVarious authors have remarked on the importance of seeds in the pre-European diet of central Australian Aborigines. The Alyawara, an Arandic-speaking group, were typical in this respect. They collected edible seeds from nearly half the eighty-five plant species in their traditional subsistence inven...Australia; Aborigines; Foraging; Seeds1981
4 Hartmann, Donald P.Cautionary note on the use of omega squared to evaluate the effectiveness of behavioral treatmentsEstimating the magnitude of treatment effects has been recommended as a solution to the problems associated with conventional hypothesis testing. In comparison to tradition statistical tests of treatment effectiveness, omega squared (ω2) and related magnitude of effect statistics provide a graduat...Magnitude of effects; Omega squared1981
5 Horch, Kenneth W.Changes in primary afferent depolarization of sensory neurones during peripheral nerve regeneration in the catI. Micro-electrode recordings were made from normal and regenerating sural nerve fibres in cats. Increases in the excitability of the central terminals of these fibres after conditioning stimulation of other sural nerve fibres were taken as evidence for primary afferent depolarization. 2. At all...Micro-electrode recording; Nerve regeneration; Primary afferent depolarization1981
6 Firmage, Edwin B.Church in politics?I BELIEVE that the Church has a right and in fact an obligation to speak out on issues which affect either the spiritual or the moral well-being of our Heavenly Father's children.
