Validity of the K-Bit and a WISC-III short form with a sample of adolescent young offenders
(1995)The present study investigated the concurrent validity and testretest reliability of the Kaufman Brief Intelligence Test (K-BIT; Kaufman & Kaufman, 1990) by comparing it to the full scale administration of the Wechsler ... -
Variability of ionic magnesium
(2001)With the invention o f the ion-selective electrode, ionic magnesium (iMg), the biologically active form of Mg, is a common blood assay. There is some evidence that iMg has considerable within subject variability. To ... -
Variable interval schedule control of dispersion and density
(1984)The effects of Variable Interval (VI) schedules of reinforcement on the dispersion patterns and aggregate densities of a small population of rats was studied. Eight male rats were permanently housed in an arena in which ... -
Variable ratio schedule control of dispersion in a patchy environment
(1989)Current ecological theory suggests that foraging animals are controlled by the distribution and abundance of food resources. Contemporary ecological research focuses on optimizing resources through the maximization of ... -
Variation of syllepsis in eleven tamarack [Larix laricina (Du Roi) K. Koch] provenances in Northwestern Ontario and its relation with height growth
(1990)Variation in syllepsis of tamarack and its relationship to juvenile height growth in eleven tamarack provenances from northwestern Ontario was evaluated in a four-year-old clonal test planted at Thunder Bay, Ontario. ... -
Variation of wood properties in a single stem of jack pine (Pinus banksiana Lamb.)
(2002)Radial and axial variation of tracheid length, relative density, ring width, radial and tangential shrinkage, and juvenile and mature wood volume were studied in a single stem of jack pine, 37 km north of Thunder Bay. ... -
Variation of wood properties within a dominant and suppressed tree of tamarack (Larix laricina (Du Roi) K. Koch)
(1987)Radial and axial variations of tracheid length, specific gravity, ring width, and latewood percentage were studied from the stems of a dominant and a suppressed tamarack tree. The trees were 81 and 83 years old respectively, ... -
Variations in metamorphic grade in metapelites in transects across the Quetico Subprovince north of Thunder Bay, Ontario
(1992)The Quetico subprovince is a northeast-southwest striking linear belt of migmatites, gneisses, and metasedimentary rocks. These Archean rocks form part of the southern Superior Province- This study involves an examination ... -
Varying food quality and its influence on spruce budworm growth, development, and fecundity
(1995)These studies assess how changing food quality influences spruce budworm, Choristoneura fumiferana (Clem.), in terms of the performance characteristics of survival, development, growth, and fecundity. The components of ... -
Vegetation and vegetation-environment relationships in a muskeg-fen near Thunder Bay, Ontario
(1979)This study takes place in an endangered peatland within the city of Thunder Bay Ontario. The study area, William Bog, is one of a few remaining peatlands in the Thunder Bay district which have developed on abandoned Minong ... -
Vegetation response to harvesting, harvesting and prescribed-burning and wildfire in Northwestern Ontario : patterns of reproductive strategies and nutrient accumulation
(1997)Initial species composition was investigated on a group of boreal mixedwood sites that had experienced various forms of disturbance. The hypothesis explored was that environmental changes caused by different disturbances ... -
Vegetative and sexual phenology, reproductive dynamics and bud differentiation in a clonal seed orchard of white and black spruce
(1981)To evaluate the importance of phenology and strobilus production in a clonal seed orchard of white and black spruce, 14 clones of each species represented by 4 ramets each, were selected from the Mattawin seed orchard. ... -
Verbal content and affective response in an interview : as a function of experimenter gaze direction
(1974)This study was designed to investigate the effects of one's looking or not looking at another's eyes upon the content of the other's speech and his affective response to the encounter. The relationships between experimenter ... -
Vibration suppression in a traversing mass-cantilever beam system
(2003)A cantilever beam carrying a traversing spring-mass system is modeled. Applications of the system include robot traversing on space trusses, loads moving along stacker cranes carrying moving loads in a large warehouse, ... -
Violent and aggressive students in Newfoundland and Labrador
(2002)Youth violence is a very real problem in North American schools. Understanding youth violence and aggression is key to developing effective school programs to reduce the number of violent acts in schools. This was a ... -
Vision-based trajectory tracking algorithm with obstacle avoidance for a wheeled mobile robot
(2005)Wheeled mobile robots are becoming increasingly important in industry as means of transportation, inspection, and operation because of their efficiency and flexibility. The design of efficient algorithms for autonomous ... -
Visual cryptography with cheating shares
(2006)Visual cryptography is a technique that applies the human visual system to decode encrypted information, such as text, image and number, without any sophisticated devices and computing capabilities. Therefore, compared ... -
Walk, stop, search : the effect of simulated motion on visual attention
(2006)Responses in covert orienting of visual attention tasks (COVAT) produce a biphasic pattern of results. When the stimulus onset asynchrony (SOA) is less than 300 ms, reaction times (RTs) to cued targets are faster than ...
