Engineers and technicians : the effect of cognitive style and gender on visual information processin
The purpose of this project was to identify in a subject group of engineers and
technicians (N = 62) a preferred mode of representation for facilitating correct recall of
information from complex graphics. The modes of representation were black and white
(b&w) block, b&w icon, color block, and color icon. The researcher's test instrument
included twelve complex graphics (six b&w and six color - three per mode). Each
graphics presentation was followed by two multiple-choice questions. Recall

Effects of sample solvent composition and injection volume on chromatographic peak profiles of methy
The effects of sample solvent composition and the
injection volume, on the chromatographic peak profiles of two
carbamate derivatives, methyl 2-benzimidazolecarbamate (MBC)
and 3-butyl-2,4-dioxo[1,2-a]-s-triazinobenzimidazole (STB),
were studied using reverse phase high performance liquid
chromatograph. The study examined the effects of acetonitrile
percentage in the sample solvent from 5 to 50%, effects of
methanol percentage from 5 to 50%, effects of pH increase from
4.42 to 9.10, and effect o
Effects of intracerebroventricular bombesin administration on local cerebral glucose utilization in
Intracerebroventricular (ICV) administration of bombesin (BN) induces a
syndrome characterized by stereotypic locomotion and grooming,
hyperactivity and sleep elimination, hyperglycemia and hypothermia,
hyperhemodynamics, feeding inhibition, and gastrointestinal function
changes. Mammalian BN-like peptides (MBNs), e.g. gastrin-releasing
peptide (GRP), Neuromedin C (NMC), and Neuromedin B (NMB), have been
detected in the central nervous system. Radio-labeled BN binds to specific
sites in discrete

House Finches (CarpQdacqs mexiCAnuS) were introduced to
Long Island, New York from southern'California in 1940.
Apparently, an initial sample of less than 100 birds has given
rise to a population that now occupies much of the eastern United
States. This study was to determine if morphological and
reproductive changes have taken place in introduced eastern
birds, which have colonized a novel environment. A study area in
Goleta, California (CAL) represented the parental population
whereas for comp

Concept analysis in social studies
This project was undertaken because of a need to analyse
concepts in social science more specifically and sequence them
more carefully in a social science program. Concepts have been
identified vaguely on many curriculum documents or left in
isolation from each other when they are specifically identified.
The project's aim was to identify a method for analysing
concepts and sequencing their teaching on some rational basis.
Once the method for analysing concepts was identified a

examined using high functioning Grades Four and Five
students who had been tested with the WISC-R .for the purpose
of gifted identification and placement. The control group,
who did not own and .play video games on a sustained basis,
and the experimental group, who did own a video game system
and had some mastery of video games, including the -Nintendo

Comparative study of bovine heart and bacillus subtilis cytochrome c oxidase vesicles and the influe
Studies on the steady state behavior of soluble cytochrome c oxidase are
extensive. These studies have examined the influence of ionic strength and pH
and may provide answers to questions such as the link between proton
translocation and charge separation. The present study examined the influence
of external bulk pH on ApH formation, biphasic kinetics, and steady state
reduction of cytochromes c and a of cytochrome c oxidase in proteoliposomes.
Bulk pH has an appreciable effect on ApH formation
Caseflow management and the politics of professionalism : lawyers and independent paralegals
Caseflow Management is a public sector program designed to promote effective
management of cases through the resolution process in the public court system. Given its
public nature caseflow management policy is ultimately an exercise in political will. To
date that political will has been dominated by the legal profession which has influenced
the Ministry of the Attorney General to limit the term~ of reference for caseflow
management and its application to a narrow range of alternatives which are
Broad reduction and adoption in ring-billed gulls (Larus Delaworensis): the potential for inergenera
Patterns of intra-clutch egg size variation and intra-clutch hatch
intervals in the Ring-billed gull (Larus delawarensis) were documented
during the peak nesting period of two consecutive breeding seasons, at a
colony near Port Colborne, Ontario. Egg size decreased with laying order;
third laid eggs were significantly smaller than first laid eggs. Hatching
of the third egg was delayed from that of first and second eggs. Intraclutch
egg size differences established initial size disparities among
Brillouin spectroscopy : measurement of elastic and photoelastic constants of some alkali holide cry
The assembly and testing of apparatus for the measurement
of elastic and photoelastic constants by Brillouin scattering,
using a Fabry-Perot interferometer and with argon ion laser
excitation is described. Such measurements are performed on
NaCI, KBr and LiF using the A = 488.0 nm laser line. The
elastic constants obtained here are in very good agreement
with the ultrasonic data for all three materials. The discrepancy

performed. The fungi Cunninghamella elegans ATCC 26269, Rhizopus
arrhizus ATCC 11145, and Mortierella isabellina NRRL 1757 were
studied in this regard. Of the aza heteroaromatics, only dibenzopyrrole

Biosynthesis of benzyliasoquinoline alkaloids
This research was carried out to obtain a convenient route for the
synthesis of [7_ 14C]-p-hydroxy benzaldehyde.
Section 1 of the thesis includes a route involving intermediates with
protecting groups like benzyl and methyl ethers of the phenols. The
benzyl ethers afforded the product in relatively better yield. The overall
synthesis involves four steps.
Section 2 describes the reactions carried out directly on phenols,
and a three step pathway is obtained for the synthesis of p-hydroxy

of the territory of male Eastern Meadowlarks (Sturnella magna) in
order to determine whether there was a correlation between any of
the attributes investigated and the number of females attracted

eight monogamous, were studied in 1982 and sixteen males.of which .. seven were polygynous and nine ~onogamous, were studied in 1983.

Assessment of chromatin activity in mouse and human tissues
Pancreatic deoxyribonuclease preferentially digests active genes
during all phases of the cell cycle including mitosis. Recently, a DNAse
I-directed in ~ nick translation technique has been used to demonstrate
differences in the DNAse I sensitivity of euchromatic and heterochromatic
regions of mitotic chromosomes. This ill ~ technique has been used in
this study to ask whether facultative heterochromatin of the inactive X
chromosome can be distinguished from the active X chromosome in mouse and
Assessing the psychometric properties of dream content questionnaires
The present study was the first of its kind to systematically explore the
psychometric properties of dream content questionnaires as measures of dream
experience. One hundred and six University students filled out the Dream Content
Questionnaire (DCQ) and kept a 14-day dream diary on two separate occasions,
in addition to filling out the NEO-PI-R and Multidimensional Personality
Questionnaire and measures of spatial ability and imaginativeness. The DCQ's
reliability was acceptable, as was its di
