The development of hypothesis testing behaviour in children
(1973)This experiment investigated whether six, eight, and ten year-old children are capable of simultaneously using more than one hypothesis at a time, or whether children can test only one at a time in a discrimination learning ... -
Development of junior intermediate preservice teachers' mathematical knowledge and values / by Carlos Zerpa.
(2008)This research thesis is composed of two studies. The first study examined the validity and reliability of a locally developed instrument called the Perceptions of Mathematics (POM) questionnaire (Kajander, 2005). The POM ... -
Development of nonlinear 3-D, and novel 2-D optical microscope imaging systems for time-lapse imaging
(2004)The design and development of a nonlinear two-photon, 3-D microscope imaging system, software for manipulation of 2-D and 3-D images, and the operation of a novel 2-D imaging system used for monitoring cultured live cell ... -
Development of optimal breeding zones for white spruce in Ontario under current, past, and anticipated future climate change / by Ashley Marie Thomson.
(2008)Tree breeding zones are delimited areas where trees are selected and bred, and their progeny are planted. Within these zones, the level of adaptation between seedlings and planting sites is controlled to ensure adequate ... -
Development of restrictive disclosure in children's communication with peers
(1986)Research supports the conclusion that adults show a pattern of restrictive disclosure in which they choose to disclose intimate information to friends rather than nonfriends. From a developmental perspective, however, ... -
Dielectric and infrared studies of radio frequency processes in some alcohols
(1988)In this thesis, the results of dielectric studies on a number of aliphatic alcohol molecules with variable chain lengths are presented. This investigation was complemented by infrared and viscosity measurements. Dielectric ... -
Dielectric relaxation and infrared studies of hydrogen bonding
(1985)Dielectric relaxation and infrared study of a number of associating (H-bonding) compounds in glassy media, mainly polystyrene, have been carried out. The dielectric measurements by a General Radio 1621 Precision ... -
Dielectric relaxation studies of some diaryl molecules in polystyrene matrices
(1978)Dielectric relaxation studies of a number of diaryl molecules dispersed in atactic polystyrene and in some cases as solid discs have been carried out. Preparation of the polystyrene matrices and the solid disks, and the ... -
Dielectric studies of molecular and intramolecular motions in polystryrene matrices
(1977)Dielectric absorption studies of a variety of polar solutes containing rotatable groups and of some analogous rigid molecules dispersed in atactic polystyrene have been carried out. Preparation of the solutions as solid ... -
Dielectric studies of molecular motions in some solids
(1982)Dielectric absorption of a number of nonpolar, weakly polar and fairly polar molecules in the pure solid state are studied. Measurements of these solids using either a General Radio 1621 Precision Capacitance Measurement ... -
Dielectric studies of rigid and flexible molecules in various media
(1984)This thesis investigates mainly the molecular and intramolecular relaxation processes of some aromatic and aliphatic molecules containing rotatable polar groups and some analogous rigid molecules dispersed in (a) ... -
Dietary restraint : the role of causal attributions
(1995)Previous studies have indicated that restrained and unrestrained eaters exhibit dififerent eating patterns in response to preloading or no preloading. After a preload, restrained eaters tend to exhibit counterregulatory ... -
Dieting practices, influences, beliefs and self-concept of female high school students
(1991)There has been a recent explosion of interest in anorexia nervosa and bulimia nervosa. There are many social influences which are thought to encourage women to strive for unrealistic thinness. The suggestion that with early ... -
Differences between elderly and young drivers : driving vigilance in two tasks
(2007)According to statistics for 2003, 9 in 100,000 people in Canada died from driving accidents. A high percentage (30-40%) of these took place due to sleepiness on monotonous road conditions. Therefore, driver vigilance must ... -
Differentiable and rough norms
(1970)The principal question discussed in this dissertation is the problem of characterizing the existence of admissible Frechet differentiable norms on Banach spaces. In the first chapter the basic concepts of normed linear ... -
Differential item and test functioning of the Brief Child and Family Phone Interview in First Nations and non-First Nations children and adolescents / by Dana Bova.
(2006)In 2001 the Ontario Ministry of Social Services mandated that all Ontario funded providers of children mental health services utilize the BCFPI (Brief Child and Family Phone Interview) which assesses emotional and behavioural ... -
Diffusion of impurities from ion implants in silicon
(1974)The use of shallow single and double impurity ion implants as diffusion sources was studied on bare (111) silicon wafers implanted at room temperature with 45 KeV boron, phosphorus and arsenic. The samples were diffused ... -
Dimensional and crystallographic fabric development in experimentally deformed synthetic aggregate and natural rocks
(1990)Calcite Portland-cement aggregate samples were deformed triaxially at 25 deg. with confining pressures of 200 Mpa. The samples were deformed under experimental approximations of pure shear (dry and wet experimental ...
