abstract:
A comprehensive elemental, isotopic and microstructural analyses was
undertaken of brachiopod calcites from the Hamilton Group (Middle Devonian),
Clinton Group (Middle Silurian) and Middle to Upper Ordovician strata of
Ontario and New York State. The majority of specimens were microstructurally
and chemically preserved in a pristine state, although a number of specimens
show some degree of post-depositional alteration. Brachiopod calcites from the
Hamilton and Clinton Groups were altered by marine derived waters whereas
Trenton Group (Middle Ordovician) brachiopods altered in meteorically derived
fluids.
Analysis of the elemental and isotopic compositions of pristine Hamilton
Group brachiopods indicates there are several chemical relationships inherent
to brachiopod calcite. Taxonomic differentiation of Mg, Sr and Na contents was
evident in three co-occuring species from the Hamilton Group. Mean Mg
contents of pristine brachiopods were respectively Athyris spiriferoides
(1309ppm), Mucrospirifer mucronatus (1035ppm) and Mediospirifer audacula
(789ppm). Similarly, taxonomic differentiation of shell calcite compositions was
observed in co-occuring brachiopods from the Clinton Group (Middle Silurian)
and the Trenton Group (Middle Ordovician). The taxonomic control of elemental
regulation into shell calcite is probably related to the slightly different
physiological systems and secretory mechanisms.
A relationship was observed in Hamilton Group species between the
depth of respective brachiopod communities and their Mg, Sr and Na contents.
These elements were depleted in the shell calcites of deeper brachiopods
compared to their counterparts in shallower reaches. Apparently shell calcite
elemental composition is related to environmental conditions of the depositional
setting, which may have controlled the secretory regime, mineral morphology of
shell calcite and precipitation rates of each species. Despite the change in Mg,
Sr and Na contents between beds and formations in response to environmental
conditions, the taxonomic differentiation of shell calcite composition is
maintained. Thus, it may be possible to predict relative depth changes in
paleoenvironmental reconstructions using brachiopod calcite. This relationship
of brachiopod chemistry to depth was also tested within a transgressiveregressive
(T-R) cycle in the Rochester Shale Formation (Middle Silurian).
Decreasing Mg, Sr and Na contents were observed in the transition from the
shallow carbonates of the Irondequoit Formation to the deeper shales of the
lowest 2 m of Rochester Shale. However, no isotopic and elemental trends
were observed within the entire T-R cycle which suggests that either the water
conditions did not change significantly or that the cycle is illusory.
A similar relationship was observed between the Fe and Mn chemistries
of shell calcite and redox/paleo-oxygen conditions. Hamilton Group
brachiopods analysed from deeper areas of the shelf are enriched in Mn and Fe
relative to those from shallow zones. The presence of black shales and
dysaerobic faunas, during deposition of the Hamilton Group, suggests that the
waters of the northern Appalachian Basin were stratified. The deeper
brachiopods were marginally positioned above an oxycline and their shell
calcites reflect periodic incursions of oxygen depleted water. Furthermore,
analysis of Dalmanella from the black shales of the Collingwood Shale (Upper
Ordovician) in comparison to those from the carbonates of the Verulam
Formation (Middle Ordovician) confirm the relationship of Fe and Mn contents to
periodic but not permanent incursions of low oxygen waters.
The isotopic compositions of brachiopod calcite found in Hamilton Group
(813C; +2.5% 0 to +5.5% 0; 8180 -2.50/00 to -4.00/00) and Clinton Group (813C;
+4.00/00 to +6.0; 8180; -1.8% 0 to -3.60/ 00) are heavier than previously reported.

Uncorrected paleotemperatures (assuming normal salinity, 0% 0 SMOW and no
fractionation effects) derived from these isotopic values suggest that the Clinton
sea temperature (Middle Silurian) ranged from 18°C to 28°C and Hamilton seas
(Middle Devonian) ranged between 24°C and 29°C. In addition, the isotopic
variation of brachiopod shell calcite is significant and is related to
environmental conditions. Within a single time-correlative shell bed (the
Demissa Bed; Hamilton Group) a positive isotopic shift of 2-2.5% 0 in 013C
compositions and a positive shift of 1.0-1.50/00 in 0180 composition of shell
calcite is observed, corresponding with a deepening of brachiopod habitats
toward the axis of the Appalachian Basin. Moroever, a faunal succession from
deeper Ambocoelia dominated brachiopod association to a shallow
Tropidoleptus dominated assocation is reflected by isotopic shifts of 1.0-1.50/00.
Although, other studies have emphasized the significance of ±20/oo shifts in
brachiopod isotopic compositions, the recognition of isotopic variability in
brachiopod calcite within single beds and within depositional settings such as
the Appalachian Basin has important implications for the interpretation of
secular isotopic trends. A significant proportion of the variation observed
isotopic distribution during the Paleozoic is related to environmental conditions
within the depositional setting.


title: Biosynthesis of benzyliasoquinoline alkaloids

subject: Alkaloids. Biosynthesis. Benzaldehyde. Isoquinoline.

abstract:
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
benzaldehyde, which was repeated on labelled compounds to obtain [7_14C]p-
hydroxy benzaldehyde. The synthesis involves the reaction of p-bromophenol
with Cu14CN to yield [7_ 14C]-p-cyano phenol, which is then reduced
to the aldehyde by means of a simple and clean photolysis method.
The same route was tried out to get 3,4-dihydroxybenzaldehyde
and was found to work equally well for the synthesis of this compound.
Section 3 deals with the isolation of labelled alkaloids, corydaline,
protopine and reticu1ine from [2-3H,1-14C]-dopamine (3H/ 14C ratio = 4)
fed Corydalis solida. 3H/14C ratios in the labelled alkaloids were
determined. The uncorrected values showed almost 50% loss of 3H relative
to 14C in reticuline, and roughly 75% loss of the 3H relative to 14C
in corydaline and protopine.

abstract:
Incubations of several polycyclic heteroaromatic compounds and two
polycyclic aromatic hydrocarbons with a series of common fungi have been
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
gave a ring hydroxylated product following the incubation with C.
elegans. From the thio heteroaromatics studied, dibenzothiophene was
metabolized by all the three fungi and thioxanthone by C. elegans and
M. isabellina giving sulfones and sulphoxides. Thiochromanone was
metabolized stereoselectively to the corresponding sulphoxide by C.
elegans. Methyl substituted thioxanthones on incubation with C.
elegans produced oxidative products, arising from S -oxidation and
hydroxylation at the methyl group. Of the cyclic ketones studied, only
fluorenone was reduced to hydroxyfluorene and this metabolism is
compared with that reported with cytochrome P-450 monooxygenases of
hepatic microsomes.
A series of para-substituted ethylbenzenes has been transformed
stereoselectively to the 1-phenylethanols by incubation with M.
isabellina. Comparisons of the enantiomeric purities obtained from
products with their respective para substituent of the same steric size
but different electronic properties indicate that the stereoselectivity
of hydroxylation at benzylic carbon may be susceptible to electron
donating or withdrawing factors in some cases, but that observation is not va lid in all the comparisons. The stereochemistry of the reaction
is discussed in terms of three possible steps, ethylbenzene ---)
1-phenylethanol ---) acetophenone ---) 1-phenylethanol. This
metabolic pathway could account for the inconsistencies observed in the
comparisons of optical purities and electronic character of para
substituents. Furthermore, formation of 2-phenylethanol (in some
cases), l-(p-acetylphenyl)ethanol from p-diethylbenzene, and
N-acetylation of p-ethylaniline was observed. n-Propylbenzene was also
converted to optically active 1-phenylpropanol.
Acetophenone, p-ethylacetophenone, and o(,~,~-trifluoroacetophenone
were transformed to 1-phenylethanol, l-(p-ethylphenyl)ethanol, and
1-phenyl-2,2,2-trifluoroethanol, respectively, with high chemical and
excellent optical yields.
The 13 C NMR spectra of several substrates and metabolic
products have been reported and assigned for the first time.

subject:

abstract:
The influence of male body weight on the aggressive and
mating behaviour of male Gryllus integer was studied under
laboratory conditions. The relationship between adult age and
weight was first determined; female weight increased and male
weight decreased with age. Virgin males that had been isolated
since the adult molt were paired for similar age and a difference
in weight of greater than 200 mg. Paired males and a virgin
female were observed in a glass arena for 24 minutes or until a
mating occurred. Larger males mated significantly more often
than smaller males. Larger males attacked more often, were more
successful in aggressive encounters and had more contact with the
female. Males that did not mate had lower rates of courtship and
mounts than males that mated. Females in trials that did not
result in a mating were signifcantly heavier than females in
trials that resulted in a mating. Larger males that mated were
significantly closer in weight to the weight of the female than
larger males in trials that did not result in a mating. Larger
males in trials that did not result in a mating had higher rates
of aggressive stridulation than larger males that mated.
Male weight is therefore important in mating success;
fitness traits should theoretically show low genetic variability.
However, significant heritability values were found for live
weight, dry weight, head width, pronotum width and length, hind
femur length and forewing length when estimated from the
regression of offspring on mid-parent values, offspring and
female and male values separately and full-sib correlations. The heritability of hind femur width was significant when estimated
from the regression of offspring on male parent and from full-sib
correlations. Heritability estimates of forewing length were
significantly higher when estimated from the regression of
offspring on female parent than when estimated from the
regression of offspring on male parent. High phenotypic, genetic
and environmental correlations were found between all pairs of
traits. Data on male mating success and the heritability of
fitness traits were discussed in terms of the maintenance of
genetic variability.

abstract:
Breeding parameters of Great Cormorants (PkaZac/iOCOfiCLX CCUibo dCUtbo) and
Double-crested Cormorants (P. CLU/uXuA CMJhLtllb) were examined at two mixed
species colonies at Cape Tryon and Durell Point, Prince Edward Island from
1976 to 1978. Differential access to nests at the two colony sites resulted
in more complete demographic data for P. CCUibo than for P. CLUJiituA.
In 1911j P. CCtfibo was present at both colonies by 21 March, whereas
P. auAAJtuA did not return until 1 April and 16 April at Cape Tryon and
Durell Point, respectively. Differences in the arrival chronology by
individuals of each species and differences in the time of nest site
occupation according to age, are suggested as factors influencing the nest
site distribution of P. CXUtbo and P. aiVtituA at Cape Tryon.
Forty-eight P. dOJtbo chicks banded at the Durell Point colony between
19 74 and 19 76 returned there to nest as two- to four-year olds in 19 77 and
19 78. Unmarked individuals with clutch-starts in April were likely greater
than four years old as all marked two to four-year olds (with one possible
exception) in 19 77 and 1978 had clutch-starts in May and June.
Seasonal variation in the breeding success of P. dOJibo individuals was
examined at Durell Point in 1977. Mean clutch-size, hatching success and
fledging success exhibited a seasonal decline. Four- and 5-egg clutches
represented the majority (75%) of all P. CCUibo clutches at Durell Point in
1977 and had the highest reproductive success (0.48 and 0.43 chicks fledged
per egg laid respectively). Smaller clutches produced small broods with
significantly higher chick mortality while larger clutches suffered high
egg loss prior to clutch completion.

abstract:
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
between ultrasonic and hypersonic sound velocities
which was reported by some authors for KBr and LiF is not
confirmed, and the elastic constants obtained for LiF are the
most accurate to date. Also, the present photoelastic constants
are in good agreement with the data obtained by ultrasonic
techniques for all three crystals. The results for the
KBr and LiF crystals constitute the first set of photoelastic
constants obtained for these materials by Brillouin spectroscopy.
Our results for LiF are the best available to date.


title: Broad reduction and adoption in ring-billed gulls (Larus Delaworensis): the potential for inergenerational conflict

subject: Ring-billed gull--Ontario--Port Colborne.

subject: Eggs--Incubation.

subject: Eggs--Hatchability.

abstract:
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
chicks at hatch. Hatch intervals further exaggerated size disparities
during the early post brood completion period. Competitive asymmetries
among chicks were associated with increased mortality rates among third
hatched chicks despite the lack of evidence of a sibling feeding hierarchy.
Fledging success in 1987 was greater than in 1988. A "brood reduction
strategy" appears to have enabled parents in 1987, to obtain an extra unit
of reproductive fitness, while in 1988 parents were often unable to raise
the entire brood and third chicks likely represented insurance
reproductive value.
Experimental broods (1988) were created in which hatch intervals
were double those of natural intervals. The size disparities among chicks
were significantly greater than in control broods, and the pattern of
mortality among chicks suggested that first chicks benefited at a cost to
second and third chicks. Parents of peak experimental broods achieved a
fledging success rate similar to that of control broods.
Characteristics of chick adoptions were also recorded. In each study
year, 9 chicks abandoned their natal territories, 6 of which were adopted.
Chicks consistently established themselves into broods where they were
older than resident chicks. No direct evidence of cost to foster parents,
or benefits to adopted chicks was obtained, although fledging success of
adopted chicks was high.


title: Business leadership in the classroom

subject: Leadership--Study and teaching (Graduate)

subject: Action research in education.

abstract:
This action research assesses a framework that assists
business educators in promoting leadership within a
classroom. It is designed to better prepare students to
assume leadership and fill the "leadership gap" in
business. Two classes of 2nd-year community college
business students participated in running and managing
their own business community as teams of sales
professionals by developing and practicing their own
individual leadership for 28 weeks during their sales
courses. The intent was to assess the development of
leadership resulting from the implementation of the
"Business Leadership in the Classroom" framework. This
framework balances leadership principles to simulate a
business environment with the practical elements of a
learning community under the facilitation of an experienced
business educator. The action research approach was used
to assess and adjust approaches to business leadership on a
continuous basis throughout the research.
Data were collected from 61 students based on
journals, surveys, peer group reviews, and my (facilitator)
reflective journal.The findings reveal that both individual and
collective business leadership views and practical skills
developed over time. A business leadership mind-set
evolved that ranged from a general awareness of the
importance of leadership, to a conscious and deliberate use
of individual leadership. Areas important in building a
progression of leadership included: leadership teams,
membership roles, weekly leadership teams, peer feedback,
and activity-based learning. Emerging themes included
leadership, leadership style, teamwork, as well as
influence and motivation. The research framework was
effective in supporting the development of business
leadership but required some adjustments. These included
increased structure and feedback mechanisms.
Interpretation of the findings demonstrates the
importance of real-world practical education in the
classroom. Results show how focusing on a single mind-set
such as business leadership, can result in enormous
individual growth and development. When business students
are encouraged to act as real businesspeople, managing
their own learning, the results are effective in preparing
them for the business world. All participants expressed
their leadership in different ways based on personality and
individual strengths. There was an overwhelming and, in some cases, passionate interest in leadership. The use of
action research with a range of data collection methods
provides a way to measure and track individual student
learning and to generate adjustments to the research
framework design and learning approaches.
The findings generate implications and recommendations
to continue this research further. Key recommendations
center around how to ensure leadership development is
sustained, including improved approaches to heighten the
real-world feel of the classroom. Specifically, the use of
leadership goals and action plans for each individual
participant and an active use of outside business resource
people as contacts for participants is recommended.

Abstract
The aim of this research project is to draw on accounts of experiences ofborder crossing
and regulation at the Canada/U.S. border at Niagara in order to illuminate the dynamics of
differentiation and inequality at this site. The research is informed by claims that the world is
turning into a global village due to transnational flows oftechnology, infonnation, capital and
people. Much of the available literature on globalization shows that while the transfer of
technology, information, and capital are enhanced, the transnational movement of people is both
facilitated and constrained in complex and unequal ways.
In this project, the workings of facilitation and constraint were explored through an
analysis often interviews with people who had spent a substantial portion oftheir childhood (e.g.
5 years) in a Canadian border community. The interviewees were at the time ofthe research
between the ages of 19 and 25. Because most ofthe respondents were 'white' Canadians of
working to upper middle class status, my focus was to explore how 'whiteness' as privilege may
translate into enhanced movement across borders and how 'white' people may internalize and
enjoy this privilege but may often deny its reality. I was also interested in how inequality is
perceived, understood, and legitimated by these relatively privileged people.
My analysis ofthe ten accounts ofborder crossing and regulation suggests that
differentially situated people experience border crossing differently. An important finding is that
while relatively privileged border crossers perceived and often problernatized differential
treatment based on external factors such as physical appearance, and especially race, most did
not challenge such treatment but rather saw it as acceptable. These findings are located within
newer literature that addresses the increasing securitization ofborders and migration in western
societies.

Ten superintendents~ 5 male and 5 female~ were randomly selected from a
possible 33 males and 9 females in the Niagara and Hamilton regions. The
participants were interviewed through a guided interview process coupled with
an accounting of their educational and career histories. They were asked to
discuss significant aspects of their careers such as the support they had received
from families, from mentors and from involvement in networks. The data
collected were then analyzed for similarities and differences both within and
between the two gender cohorts. Upon analysis, it was found that the female
and male administrators possessed differences in their personal backgrounds as
well as their career and educational histories. Differences were also found in
the perceived role of mentors, and networks. The ways in which the female
administrators experienced their careers were found to be quite different from
the ways in which the male administrators experienced their careers.

abstract:
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 primarily in
the interest of the legal profession. This thesis will explain the nature and extent of the
politics within the legal profession that impact on caseflow management and demonstrate
the potential for better serving the public interest by eXl~anding its terms of reference to
incorporate independent paralegals and public / private sector partnerships in the Ontario
Provincial Court System for highway traffic offences and other matters of a summary
conviction nature.

abstract:
The distribution of excitation energy between the two
photosystems (PSII and PSI) of photosynthesis is regulated by the
light state transition. Three models have been proposed for the
mechanism of the state transition in phycobilisome (PBS) containing
organisms, two involving protein phosphorylation. A procedure for
the rapid isolation of thylakoid membranes and PBS fractions from
the cyanobacterium Synechococcus m. PCC 6301 in light state 1 and
light state 2 was developed. The phosphorylation of thylakoid and
soluble proteins rapidly isolated from intact cells in state 1 and state
2 was investigated. 77 K fluorescence emission spectra revealed that
rapidly isolated thylakoid membranes retained the excitation energy
distribution characteristic of intact cells in state 1 and state 2.
Phosphoproteins were identified by gel electrophoresis of both
thylakoid membrane and phycobilisome fractions isolated from cells
labelled with 32p orthophosphate. The results showed very close
phosphoprotein patterns for either thylakoid membrane or PBS
fractions in state 1 and state 2. These results do not support proposed
models for the state transition which required phosphorylation of
PBS or thylakoid membrane proteins.

subject: Nuclear magnetic resonance spectroscopy.

abstract:
The preparation of chelated difluoroboron cations (DD)BF2+, where DD is a
saturated polydentate tertiary-amine or polydentate aromatic ligand, has been systematically
studied by using multinuclear solution and solid state nuclear magnetic resonance
spectroscopy and fast atom bombardment mass spectrometry. Three new methods of
synthesis of (DD)BF2+ cations are reported, and compared with the previous method of
reacting a chelating donor with Et20.BF3. The methods most effective for aromatic donors
such as 1,1O-phenanthroline are ineffective for saturated polydentate tertiary-amines like
N,N,N' ,Nil ,Nil-pentamethyldiethylenetriamine.
Polydentate tertiary-amine donors that form 5-membered rings upon bidentate
chelation were found to chelate effectively when the BF2 source contained two leaving
groups (a heavy halide and a Lewis base such as pyridine =pyr or isoxazole =ISOX), i.e.,
pyr.BF2X (X = CI or Br), ISOX.BF2X and (pyr)2BF2+. Those that would form 6membered
rings upon chelation do not chelate by any of the four methods. Polydentate
aromatic ligands chelate effectively when the BF2 source contained a weak Lewis base,
e.g., ISOX.BF3, ISOX.BF2X and Et20.BF3. Bidentate chelation by polydentate tertiaryamine
and aromatic donors leads to nmr parameters that are significantly different then
their (D)2BF2+ relatives (D =monod~ntate t-amines or pyridines).
The chelated haloboron cations (DD)BFCI+, and (DD)BFBr+ were generated from
D.BFX2 adducts for all ligands that form BF2+ cations above. In addition, the (DD)BCI2+
and (DD)BBr2+ cations were formed from D.BX3 adducts by the chelating aromatic
ligands, except for the aromatic ligand 1,8-bis(dimethylamino)naphthalene, which formed
only the (DD)BF2+ cation, apparently due to its extreme steric hindrance.
Chelation by a donor is a two-step reaction. For polydentate tertiary-amine ligands,
the two rates appear to be very dependent on the two possible leaving groups on the central
boron atom. The order of increasing ease of displacement for the donors was: pyr < Cl <
Br < ISOX. The rate of chelation by polydentate aromatic ligands appears to be dependent
on the displacement of the first ligand from the boron. The order of increasing ease of
displacement for the donors was: pyr < CI < ISOX ~ Br < Et20.

abstract:
The conceptualization of childhood has changed over the centuries and appears to be
undergoing further change in our post-modern culture. While the United Nations
Convention on the Right of the Child is designed to give children everywhere basic human
rights while taking into consideration their special needs, no recent research has examined
adult attitudes toward those rights. In an attempt to understand the attitudes adults hold
regarding autonomy rights and to look for some factors that could predict those attitudes,
the current study considers values, parenting style, emotions and the issue of parent status
as possible predictor variables. A total of 90 participants took part in the research, which
had both written and interview components. Results generally failed to establish a reliable
set of predictors. However, some interesting information was obtained regarding the
endorsement of children's autonomy rights and some general conclusions were reached
about our view of children and their rights at the end of the twentieth century.

abstract:
The regenerating urodele limb is a useful model system
in which to study, in vivo, the controls of cell
proliferation and differentiation. Techniques are available
which enable one to experimentally manipulate mitogenic
influences upon the blastema, as well the morphogenesis of
the regenerating 11mb. Although classical regeneration
studies have generated a wealth of knowledge concerning
tissue interactions, little 1s known about the process at the
level of gene expression.
The aim of this project was to clone potentially
developmentally regulated genes from a newt genomic library
for use in future studies of gene expression during limb
regeneration. We decided to clone the cytoskeletal actin
gene for the following reasons: 1. its expression reflects
the proliferative and differentiatlve states of cells in
other systems 2. the high copy number of cytoplasmic actin
pseudogenes in other vertebrates and the high degree of
evolutionary sequence conservation among actin genes
increased the chance of cloning one of the newt cytoplasmic
actin genes. 3. Preliminary experiments indicated that a
newt actin could probably be identified using an available
chick ~-actln gene for a molecular probe.
Two independent recombinant phage clones, containing
actin homologous inserts, were isolated from a newt genomic
library by hybridization with the chick actin probe.
Restriction mapping identified actin homologous sequences
within the newt DNA inserts which were subcloned into the
plasmid pTZ19R. The recombinant plasmids were transformed
into the Escherichia coli strain, DHsa. Detailed restriction
maps were produced of the 5.7Kb and 3.1Kb newt DNA inserts in
the plasmids, designated pTNAl and pTNA2. The short «1.3
Kb) length of the actin homologous sequence in pTNA2
indicated that it was possibly a reverse transcript
pseudogene. Problems associated with molecular cloning of
DNA sequences from N. viridescens are discussed with respect
to the large genome size and abundant highly repetitive DNA

subject: Nymphalidae--Cytology. Nymphalidae--Phylogeny. Passiflora--Cytology. Passiflora--Phylogeny. Coevolution.

abstract:
Although a substantial amount of research has been done on all aspects ofHeliconius
biology and their ecological interactions with Passiflora, there has not hitherto been a
phylogenetic examination of this association for coevolution. To test the HeliconiuslPassilfora
association for coevolutionary congruence, phylogenies for each group were established and
compared. The phylogeny for 14 species ofHeliconiinae from Costa Rica was based on
combined sequence data from rRNA ITS 2 and partial EF-1a gene regions. For the
Passifloraceae, 17 host plant species were utilized to establish a phylogeny based on tRNALeucine
and ITS 1/5.8S1 ITS 2 sequence data. The phylogenies for both groups were largely in
agreement with current classification (for Passifloraceae) and previously established
phylogenies. Associations with the large subgenera Passiflora and Decaloba correspond with
the two major Advanced Radiation groups in Heliconius. Although strict congruence above
subgenus level was not observed, broad scale congruence was evident. One main host shift as
well as other possible explanations for lack of strict congruence are suggested.


title: Commodities and their fetishism

subject:
Commodity exchanges.
Fetishism.

abstract:
Many pr oblems present themselves in at tempting t o discuss
Marx's noti on of the fetish characteristics of commodities. It has
been argued that it is one of the central points of Marx's en tir e
c or pus. 1 It has also been argued that it i s merely "a brilli an t
s oci olog i cal genera lization l ! and, even furth er, that it is an
Hi ndependent and separate entity, internally hardly related t o
Marx's economic theory" .2 How could such a theory be understo od
i n such drastically diff erent ways? Perhaps the clue is to be
f ound somewhere in Marx' s discussion of the fetishism of commodities
itself. Because of the difficulty in un derstanding fetishism ,
I intend t o examine what Marx himself has t o say first befor e
dealing with any points related to the notion of fetishism. Thus ,
the first parts of this thesis will c onsist of l ong qu otations
and repetition of what Marx has t o say. If a noti on may be called
' central' and yet 'hardly related' t o Marx's wor k at the same
time, surely a clear examination of this section is necess ary.
Aft er an examination of the initial secti ons of Cae ital ] I
intend t G examine the f ollowing : the r e lation of fetishism t o the
t he ory of alienati on; how one may regard f etishism as a pr oblem
f or philosophy; and how, in f act, the theory of fetishism is of
prime imp ortance f or an understan ding of Marx's wr itings. What I
want to stress throughout is that with o u~ an understanding of what
is inherent in the pr oduction of the commodity causing i t t o be
necessarily fetishistic, it is practically imp ossible t o understand
much of Marx's other writin gs.
A commodity appears, at fir st sight, a very
trivial thing and easi ly un derst ood. Itsanalysis
shows that it i s , in r eality , a very queer
thing , abo unding in ~taphysical s ubtleties and
theological nic eties .

abstract:
The fragmentation patterns and mass spectra of some phenyl tin and
-lead halide adducts with hexamethylphosphoramide are compared by
subjecting them t~ electron impact and fast atom bombardment ionization
in a mass spectrometer. This comparison is restricted to the
metal-containing ions. Ligand-exchange mechanisms of some of the
metal-containing species are explored by FAB-MS. Several moisturesensitive
organo-metallics and H-bonded systems have been examined by
FAB for attempted characterization, but without any success. Scavenging
and trapping of water molecules by complex aggregates in solutions of
quaternary ammonium fluorides and hydroxides are investigated by FAB to
complement previous NMR-studies.


title: Comparative study of bovine heart and bacillus subtilis cytochrome c oxidase vesicles and the influence of bulk pH on cytochrome c oxidase components

subject:
Cytochrome c.
Cytochrome oxidase.
Heart--Cytopathology.
Cattle--Cardiovascular system.

abstract:
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 and steady state reduction
levels of cytochromes c and 8. Bulk pH affected total Vmax and Km at the low
affinity binding site of cytochrome c. This study also examined the influence of
bovine serum albumin and free fatty acids on proton pumping activity in bovine
heart proteoliposomes. Proton pumping activity decreased after treatment with
BSA, and was subsequently reinstated after further treatment with FFA.
Much study in the superfamily of haem/copper oxidases has recently
been devoted to the bacterial oxidases. The present study has examined some
protein composition characteristics and bioenergetic features of Bacillus subtilis
cytochrome caa3 oxidase. Results provide evidence for the structural
composition of the enzyme in relation to the covalently bound cytochrome c to
the oxidas~. Bioenergetically, caa3 COV showed appreciable proton pumping
activity. Steady state analysis of the caa3 COV showed significantly different
cytochrome c and a reduction characteristics compared to the bovine enzyme.


title: Comparison of two measures of PSI electron transport in winter rye

subject:
Electron transport.
Photosynthesis.
Rye.

abstract:
The number of P700 (the reaction centre of
Photosystem I) converted to P700+, in winter rye, was
determined by measuring the absorbance change at 820nm . It
was found, with a single turnover flash, that thylakoids
isolated from cold grown plants have a 50% greater number of
P700 oxidized than thylakoids isolated from warm grown plants.
Incubation of thylakoids in the dark at 35 C did not change
the number of P700 oxidized. The conversion of P700 to P700+
with a single flash can be compared to a steady state rate of
electron transport using a Clark electrode. The results for
P700 oxidation using the absorbance change at 820 nm measure
effects within the PSI complex whereas the results obtained
from a Clark electrode measures steady state electron
transport between the cytochrome blf complex and the PSI
complex. In contrast to the results for P700 oxidation it was
shown, using a Clark electrode, that both thylakoids from cold
grown plants and thylakoids incubated at in the dark 35 C
exhibited 50% higher rates of electron transport than
thylakoids from warm grown plants. The correlation between the
higher rate of steady state PSI electron transport observed in
thylakoids isolated from cold grown winter rye and number of
active PSI reaction centres localizes the site of the increase
to the PSI reaction centre. In contrast the lack of
correlation after incubation at 35 C indicates the increase in
the rate of light saturated electron transport in thylakoids
isolated from cold grown plants and thylakoids incubated in
the dark at 35 C occur by different mechanisms.

subject:
Video games--Psychological aspects.

Children--Intelligence levels.
Verbal ability in children.
Performance in children.

abstract:
The strength and nature of the video game practice
effect on tests of visual and perceptual skills were
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
game, "Tetris", were each composed of 18 juniorg:r;-ade
students and were chosen from pre-existing conditions. The
experimental group corresponded to the control group in
terms of age, sex, and community.
Data on the Verbal and Performance I.Q. Scores were·
collected for both groups and the author was interested in
the difference between the Verbal and Performance Scores
within each group, anticipating a P > V outcome for the
experimental group.
The results showed a significant P > V difference in
the experimental, video game playing group, as expected, but
no significant difference between the Performance $cores of
the control and experimental groups. The results, thus,
indicated lower Verbal I.Q. Scores in the experimental group relat'ive to 'the control group.'
The study conclu~ed that information about a sUbject's
video game experience and "learhing style pref~rence is
important for a clear interpretation of the Verbal and
Performance I.Q. Scores of the WISC-R. Although the time
spent on video game play may, 'indeed, increase P~rformance
Scores relative to Verbal Scores for an individual, the
possibilities exist that the time borrowed and spent away
from language based activities may retard verbal growth
and/or that the cognitive style associated with some
Performance I.Q.subtests may have a negative effect on the
approach to the tasks on the Verbal I.Q. Scale.
The study also discussed the possibility that exposure
to ,the video game experience, in pre-puberty, can provide
spatial instruction which will result in improved spatial
skills. strong spatial skills have been linked to improved
performance and preference in mathematics, science, and
engineering and it was suggested that appropriate video game
play might be a way to involve girls more in the fields of
mathematics and science.

fluorescence (XRF) consisting of radioactive sources (secondary foil
excitor 241Am-Mo source and 55Pe source), a Si(Li) detector, and a
multichannel analyzer were employed. The XRF system was calibrated by
using sol gel thin films of known element composition and also by
sputtered thin films analyzed by the conventional Rutherford Back

sputter target composition required to produce high-Tc BiSrCaCuO films
with the desired metal composition.


title: Concept analysis in social studies

subject:
Social sciences--Study and teaching.
Social sciences--Methodology.
Concepts.

abstract:
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
questionnaire was designed and administered to a random sample
of students at the grade three, five and eight levels. The
questionnaire attempted to measure their comprehension of
specific social science concepts at several levels which
became progressively more complex. The major hypothesis was
that there would be a direct correlation between age and achievement
on the questionnaire. The raw scores were seriated and
correlated with the ages of the students using the rankdifference-
squared method.
For the majority of areas tested it was found that there
was a significant correlation between age and achievement on
the questionnaire. Variation in the correlation coefficients
generated suggests that comprehension of social science concepts
is not simply a function of age but is probably a function of
several inter-related factors such as reading ability, skill
in Basic Thinking Skills and age.
Thirty students completed each test. There were three tests
in the questionnaire.

subject: Nurses--Social aspects--Ontario.

abstract:
A convenience sample of twenty registered nurses was
recruited from two' general hospitals and two community college
nursing schools. Kelly's (1955) Personal Construct Theory
provided the theoretical framework to discover how nurses
perceived themselves as educators. The nurses completed a
self-administered Self-Perception Inventory (Soares, 1983) to
determine their perception of self as nurse and ideal self as
nurse. In an interview, each of the nurses constructed a
rank-order repertory grid adapted from Kelly's (1955) Role
Repertory Construct Test. Twelve constructs derived from the
Self-Perception Inventory (Soares, 1983) were ranked according
to a list of ten elements common to a teaching situation.
Rank order correlations among the constructs were determined
with Spearman's rho.
Using a dependent samples t-test, significant differences
were found between perceptions of current and ideal self for
staff nurses. Significant differences were also found between
nurse educators' perceptions of self and ideal self as nurse.
No significant differences were determined in perceptions of
self as nurse and ideal self as nurse between the staff nurse
and nurse educator groups with an independent samples t-test.
However, observations of single constructs revealed that
although several constructs are shared between the groups in the perception of self in a teaching situation, both groups
hold constructs that operate exclusively in their separate
domains. The nature and strength of the relationships between
the common and unique constructs are different for each group.
Nurses I self-perceptions appear to be influenced by the
historical development of nursing, role socialization during
nursing education, social expectations and gender issues in
the health care system.

subject: Hydrides.

subject: Inductively coupled plasma atomic emission spectrometry.

subject: Steel--Analysis.

abstract:
Arsenic, bismuth, germanium, antimony and tin were simultaneously determined
by continuous hydride generation and inductively coupled plasma-atomic emission
spectrometry .
I
Hydrides were introduced into four different types of gas-liquid separators. Two of
the gas-liquid separators were available in-house. A third was developed for this project and
a fourth was based on a design used by CET AC. The best signal intensity was achieved by
the type II frit-based gas-liquid separator, but the modified Cetac design gave promise for the
future, due to low relative standard deviation.
A method was developed for the determination of arsenic, bismuth, antimony and tin
in low-alloy steels. Four standard reference materials from NIST were dissolved in 10 mL
aqua regia without heat. Good agreement was obtained between experimental values and
certified values for arsenic, bismuth, antimony and tin. The method was developed to
provide the analyst with the opportunity to determine the analytes by using simple aqueous
standards to prepare calibration lines. Within the limits of the samples analyzed, the method
developed is independent of matrix.


title: Co-operative education and the development of self-esteem, an internal locus of control and work habits

abstract:
This study compared approximately 50 grade 12 students
studying In th~ co-operative education mode with
approximately 50 grade 12 students studying in a
traditional English course. Measures of self-esteem,
locus of control and work habits were compared before and
at the conclusion of one semester's involvement in the
different programs.
Using Coopersmith's Self-Esteem Inventory, the students
who had chosen to study in the co-operative education mode
scored significantly higher than the students in the
traditional course. At the end of the semester, the
co-operative education students' scores remained
significantly higher than the English students'. Although
the test showed no sjgnifi~ant changes in self-esteem.
anecdotal reports indicated that co-operative education
students had increased self-esteem over the semester. No
significant differences in locus of control were observed between the two groups at any time. Significant
differences in work habits were observed. While both
groups had the same number of absences and the same marks
before taking these courses, students who were involved in
co-operative education had significantly fewer absences
and significantly higher marks than the students studying
in the traditional course. Anecdotal reports also
indicated an improv~ment in work habits for students who
had been involved in co-operative education.
Recommendations of the study are for further research to
determine more exactly how self-esteem and work habits
develop in co-operative education students. Also.
students. parents, teachers. and administrators need to be
made aware of the success of this program.


title: Cooperative learning and elaborative interrogation: effects on children's learning

subject:
Group work in education.
Questioning.
Education, Elementary--Ontario.

abstract:
This experimental study examined the effects of
cooperative learning and a question-answering strategy
called elaborative interrogation ("Why is this fact true?")
on the learning of factual information about familiar
animals. Retention gains were compared across four study
conditions: elaborative-interrogation-plus-cooperative
learning, cooperative-learning, elaborative-interrogation,
and reading-control. Sixth-grade students (n=68) were
randomly assigned to the four conditions. All participants
were given initial training and practice in cooperative
learning procedures via three 45-minute sessions. After
studying 36 facts about six animals, students' retention
gains were measured via immediate free recall, immediate
matched association, 30-day, and GO-day matched association
tests. A priori comparisons were made to analyze the data.
For immediate free recall and immediate matched association,
significant differences were found between students in the
three experimental conditions versus those in the control
condition. Elaborative-interrogation and elaborativeinterrogation-
plus-cooperative-learning also promoted longterm
retention (measured via 30-day matched association) of
the material relative to repetitive reading with
elaborative-interrogation promoting the most durable gains (measured via GO-day matched association). The relationship
between the types of elaborative responses and probability
of subsequent retention was also examined. Even when
students were unable to provide adequate answers to the why
questions, learning was facilitated more so than repetitive
reading. In general, generation of adequate elaborations
was associated with greater probability of recall than was
provision of inadequate answers. The findings of the study
demonstrate that cooperative learning and the use of
elaborative interrogation, both individually and
collaboratively, are effective classroom procedures for
facilitating children's learning of new information.


title: Correlates and outcomes of severe bullying: internalizing maladjustments of adolescent bullies, victims and bully- victims

subject: Bullying in schools.

subject: Bullying--Psychological aspects.

subject: Identification (Psychology) in children.

abstract:
The current study examined the association between involvement in bullying and
victimization and internalizing difficulties such as self-esteem, social anxiety, depression and
body image. Possible gender differences were also examined. The participants, high school
students from Southern Ontario (N=533), were drawn from a larger, data set as part ofa study
that was completed by the Youth Lifestyle Choices: Community Research Alliance (YLCCURA).
The students completed a self-report questionnaire on a number ofmeasures; including,
bullying, victimization, self-esteem, social anxiety, depression and body image. The results of
this study suggest that those students who self-identified as victims and bully-victims also report
higher levels of anxiety and depression than controls and bullies. Severe victims and bullyvictims
had a lower body image than severe bullies and controls, whereas severe bullies seem to
have a higher body image score than controls. These results are relevant when considering
treatments and interventions for students experiencing adjustment difficulties who may also be at
risk for bullying victimization. The results also suggest that particular attention needs to be
focused on those adolescents who play multi-roles in bullying situations (i.e., bully-victims),
since these students may come to the attention ofthe school system for externalizing behaviours,
but may also need assistance for internalizing maladjustments.

title: Creativity and the working artist/teacher : the relationships

subject:
Artists as teachers.
Creative ability.
Art--Study and teaching.

abstract:
The purpose of this qualitative study was to understand the
relationships between creativity and the working artist/teacher
employed by an art college. The topic emerged from my job as an
instructor at The Ontario College of Art which was used as the
primary data resource and provided the highest caliber of
professionals to chose from.
Existent data were used to facilitate the study generated by
the research of Cawelti, Rappaport, and Wood (1992). The data were
generated by a group of 5 faculty members from The University of
Northern Iowa, recognized for their expertise in the arts (a painter,
a poet, a sculptor, a novelist, and a photographer). They were asked
to respond to the following statement: "In as much detail as you like,
list the things that you did, thought, or felt the last time you
created an artistic product. II
Cawelti, Rappaport, and Wood (1992) produced three models of
the creative process, each building on the previous, with the
resultant third,being in my opinion, an excellent illustration
(text/visual) of the creative process. Model three (Appendix D)
presented a "multi-dimensional view of the creative process: time,
space, observatility, and consciousnessll (p. 90).
Model three utilized a visual mapping device along the bottom
of the page linked to text segments above. Both the visual and the
text were interrelated so that they harmonized into a comprehensive
"picture." The parti'cipants of this qualitative study were asked to consider model three from their professional perspective as
artist/teachers.
The interpretive sciences directed the methodology. The
hermeneutic circle of continuous reflection from the whole to the
part and back to the whole was an important aspect of the data
analyses. Four members of the Foundation Department at The
Ontario College of Art were the key participants.
A series of conversational interviews was the primary source
of data collection, this was augmented by observation, fie,ldnotes,
and follow up telephone interviews. Transcripts of interviews were
returned to participants for reflection and the telephone was used to
discuss any additional -points raised.
Analysis consisted of coding and organizing data according to
emerging themes. These themes formed the basis for the narrative
stories. The text of the narrative stories were given back to each
participant for further comment. Revisions were made until both
the researcher and the participants felt that the stories reflected
reality. The resultant whole was critiqued from the researcher's
perspective.
The significance of this study was discussed as it pertains to
the working artist/teacher and areas in need of further study are
pointed out.

subject:
Calmodulin.

Asparagus--Cytochemistry.

abstract:
Numerous investigations have demonstrated large increases in
y-amino butyrate (GABA) levels in response to a variety of
stresses such as touch or cold shock (Wallace et ale 1984)
Circumstantial evidence indicating a role of Ca2
+ in these
increases includes elevated Ca2+ levels in response to touch and
cold shock (Knight et ale 1991), and the demonstration of a
calmodulin binding domain on glutamate decarboxylase (GAD), the
enzyme responsible for GABA synthesis (Baum et al 1993) In the
present study the possible role of Ca2+ and calmodulin in
stimulation of GAD and subsequent GABA accumulation was examined
using asparagus mesophyll cells. Images of cells loaded with the
Ca2+ indicator Fluo-3 revealed a rapid and transient increase in
cytosolic Ca2+ in response to cold shock. GABA levels increased
by 106% within 15 min. of cold shock. This increase was inhibited
70% by the calmodulin antagonist W7, and 42% by the Ca2+ channel
blocker La3+.. Artificial elevation of intracellular Ca2+ by the
Ca2+ionophore A23187 resulted in an 61% increase in GABA levels.
Stimulation of GABA synthesis by ABA resulted in an 83% increase
in GABA levels which was inhibited 55% by W7. These results
support the hypothesis that cold shock stimulates Ca2+ entry into
the cytosol of the cells which results in Ca2+/calmodulin
mediated activation of GAD and consequent GABA synthesis.

title: Decision-making theory applied to India's explosion of a nuclear device in May, 1974

subject: Decision making--Political aspects--India.

subject: Nuclear explosions.

abstract:
This essay reviews the decision-making process that led to India
exploding a nuclear device in May, 1974. An examination of the
Analytic, Cybernetic and Cognitive Theories of decision, will enable a
greater understanding of the events that led up to the 1974 test.
While each theory is seen to be only partially useful, it is only by
synthesising the three theories that a comprehensive account of the
1974 test can be given.
To achieve this analysis, literature on decision-making in national
security issues is reviewed, as well as the domestic and international
environment in which involved decisionmakers operated. Finally, the
rationale for the test in 1974 is examined.
The conclusion revealed is that the explosion of a nuclear device
by India in 1974 was primarily related to improving Indian international
prestige among Third World countries and uniting a rapidly disintegrating
Indian societal consensus. In themselves, individual decision-making
theories were found to be of little use, but a combination of the various
elements allowed a greater comprehension of the events leading up to the
test than might otherwise have been the case.

Variation (Biology)

abstract:
The peripheral  circulating erythrocytic system of the
rainbow trout, l3 almo gairdner , was examined in vitro in relation differences in the morphology and multiple hemoglobin system
organization of adult and juvenile  red cells.
Cells were separated by velocity sedimentation   under unit
gravity, a procedure requiring red cell exposure to an incubation
medium for periods of at least three hours. Therefore ,
this must provide an environment in which red cells remain in a
condition approximaing normalcy. Previous studies having
demonstrated commonly employed media to be ineffective in this
regard , a medium was developed through modification of Cortl and
saline. One of the principal additions to this me dium ,
norepinephrine, altered cell regulation of intracellular calcium,
magnesium and chloride concentrations. Catecholamine involvement
was also suggeste d in the synthes is of hemoglobin .
The procedure was found to separtate cells     primarily by
density and, to a lesser extent, by shape. Characterization of
red cells revealed two subpopulations to exist . The first
comprised the bulk of the cell population, and    were of greater
l ength, width, volume and major:minor axis ratio than the smaller
population; these were adult cells. The later, juvenile cells
were of smaller overall size and were more spherical in shape .
Juvenile cells also possessed fewer electrophore   tpically distinguishable
isomorphs than did adults with only eight of
eleven hemoglobin component s typically found With maturation,hemoglobin complement with the development of three more bands.
The total complement of the adult cell contained 7 cathodal bands
and four anodal hemoglobin isomorphs. Bands acquired with
maturation comprised the smallest percentage of the cells
hemoglobin. each averaging less than one-percent of the
total. Whether these additional bands are derived through
degradation and reaggregation of existing components or are the
product of pe gQy2 synthesis is not yet known.


title: Development of packaging cell lines for rescuing BAV2 viral vectors

subject:
Viral genetics.

Genetic vectors.

abstract:
The construction of adenovirus vectors for cloning and foreign gene expression requires
packaging cell lines that can complement missing viral functions caused by sequence deletions
and/or replacement with foreign DNA sequences. In this study, packaging cell lines were
designed to provide in trans the missing bovine adenovirus functions, so that recombinant
viruses could be generated.
Fetal bovine kidney and lUng cells, acquired at the trimester term from a pregnant cow,
were tranfected with both digested wild type BAV2 genomic DNA and pCMV-EI. The plasmid
pCMV-EI was specifically constructed to express El of BAV2 under the control of the
cytomegalovirus enhancer/promoter (CMV). Selection for "true" transformants by continuous
passaging showed no success in isolating immortalised cells, since the cells underwent crisis
resulting in complete cell death. Moreover, selection for G418 resistance, using the same cells,
also did not result in the isolation of an immortalised cell line and the same culture-collapse
event was observed.
The lack of success in establishing an immortalised cell line from fetal tissue prompted us
to transfect a pre-established cell line. We began by transfecting MDBK (Mardin-Dardy bovine
kidney) cells with pCMV-El-neo, which contain the bacterial selectable marker neo gene. A
series of MDBK-derived cell lines, that constitutively express bovine adenoviral (BAV) early
region 1 (El), were then isolated. Cells selected for resistance to the drug G418 were isolated
collectively for full characterisation to assess their suitability as packaging cell lines. Individual
colonies were isolated by limiting dilution and further tested for El expression and efficiency of
DNA uptake. Two cell lines, L-23 and L-24, out of 48 generated foci tested positive for £1
expression using Northern Blot analysis. DNA uptake studies, using both lipofectamine and
calcium phosphate methods, were performed to compare these cells, their parental MDBK cells,
8
and the unrelated human 293 cells as a benchmark. The results revealed that the new MDBKderived
clones were no more efficient than MDBK cells in the transient expression of transfected
DNA and that they were inferior to 293 cells, when using lacZ as the reporter gene.
In view of the inherently poor transfection efficiency of MDBK cells and their
derivatives, a number of other bovine cells were investigated for their potential as packaging
cells. The cell line CCL40 was chosen for its high efficiency in DNA uptake and subsequently
transfected with the plasmid vector pCMV El-neo. By selection with the drug G418, two cell
lines were isolated, ProCell 1 and ProCell 2. These cell lines were tested for El expression,
permissivity to BAV2 and DNA uptake efficiency, revealing a DNA uptake efficiency of 37 % ,
comparable to that of CCL40.
Attempts to rescue BAV2 mutants carrying the lacZ gene in place of £1 or £3 were
carried out by co-transfecting wild type viral DNA with either the plasmid pdlElE-Z (which
contains BAV2 sequences from 0% to 40.4% with the lacZ gene in place of the £1 region from
1.1% to 8.25%) or with the plasmid pdlE3-5-Z (which contains BAV2 sequences from 64.8% to
100% with the lacZ gene in place of the E3 region from 75.8% to 81.4%). These cotransfections
did not result in the generation of a viral mutant. The lack of mutant generation
was thought to be caused by the relative inefficiency ofDNA uptake.
Consequently, cosBAV2, a cosmid vector carrying the BAV2 genome, was modified to
carry the neo reporter gene in place of the £3 region from 75.8% to 81.4%. The use of a single
cosmid vector earring the whole genome would eliminate the need for homologous
recombination in order to generate a viral vector. Unfortunately, the transfection of cosBAV2-
neo also did not result in the generation of a viral mutant. This may have been caused by the size
of the £3 deletion, where excess sequences that are essential to the virus' survival might have
been deleted. As an extension to this study, the spontaneous E3 deletion, accidently discovered
in our viral stock, could be used as site of foreign gene insertion.

The major hypothesis of this paper is that any deviance
in syntax present in oral language will be evident in oral
r eading behaviour. Using Lee and Canter's Developmental

Sentence Scoring technique (1971) and Y. Goodman and Burke's Reading
Miscue Inventory (1972) linguistic competence was established
in t hree male children. ages 10 to 11. patterns of strengths
and weaknesses in reading were determined. and the relationships

i ndicate that oral language behaviour is closely tied to oral
r eading behaviour. This type of approach can be used as a
basis for a diagnosis of a reading difficulty and then a
prescription for language and reading skills.

subject:
Brachiopoda, Fossil--New Mexico.
Diagenesis--New Mexico.
Geochemistry--New Mexico.
Geology--New Mexico.
Geology, Stratigraphic|yPennsylvanian.

abstract:
Owing to the fact that low-Mg calcite fossil shells are so important in
paleoceanographic research, 249 brachiopod, cement and matrix specimens
from two neighboring localities (Jemez Springs and Battleship Rock), of the
Upper Pennsylvanian Madera Formation were analyzed. Of which, about 86%
of the Madera brachiopods are preserved in their pristine mineralogy,
microstructure and geochemistry. Cement and matrix samples, in contrast, have
been subjected to complete but variable post-deposition~1 alteration. It is
confirmed that the stable isotope data of brachiopods are much better than that
of matrix material in defining depositional parameters. Because there is no
uniform or constant relationship between the two data bases (e.g., from 0.1 to
3.0%0 for 0180 and from 0.2 to 6.7%0 for 013C in this study), it is not possible to
make corrections for the matrix data. Regarding the two stratigraphic sections,
elemental and petrographic analyses suggest that Jemez Springs is closer to
Penasco Uplift than Battleship Rock. Seawater at Jemez Springs is more
aerobic, and the water chemistry is more influenced by continental sources than
that at Battleship Rock. In addition, there is a relatively stronger dolomitization
in the mid-section of the Battleship Rock.
Results further suggest that no significant biogenic fractionation or vital
effects occurred during their shell secretion, suggesting that the Madera
brachiopods incorporated oxygen and carbon isotopes in equilibrium with the
ambient seawater. This conclusion is not only drawn from the temporal and
spatial analyses, but also supported by brachiopod inter-generic comparison
(Composita and Neospirifer) and statistical analysis ( t-test).


title: Dialogue journal writing: a tool for critical reflection in the adult ESL learner

subject: English language--Study and teaching--Foreign speakers.

subject: Adult education--Evaluation.

subject: English language--Written English--Study and teaching

subject: Second language acquisition.

abstract:
This study attempted to determine whether or not dialogue journal writing
encouraged critical reflection in the adult ESL (English as a Second Language) learner.
According to research in adult education and anecdotal evidence, the process ofdialogue
journal writing can facilitate critical reflection in the adult learner. However, little research
has been conducted to examine whether or not journal writing can facilitate critical
reflection in the second language learner. As a result, ten low-intermediate level adult
ESL students from Brock University's Intensive English Language Programme
participated in a dialogue journal writing programme in their writing class. The
participants wrote journal entries over a 10-week period, and were interviewed once
throughout the process to determine their perceptions ofthe journal writing experience.
They also were observed by the researcher throughout the journal writing sessions to
establish whether any behaviours or intrusions might affect the participants' writing
processes. After the content ofthe journals and the interviews, and the observations made
by the researcher were analysed, it was confirmed that, for these participants, dialogue
journal writing did not necessarily encourage critical reflection. Moreover, the
participants' perceptions ofjournal writing were that it helped them to practise the syntax,
vocabulary, and rhetorical patterns ofEnglish; nevertheless, it did not foster critical
reflection or thinking.


title: Diatoms as indicators of lake trophic status

subject:
Diatoms--Ontario.
Diatoms, Fossil--Ontario.
Lakes--Ontario.
Eutrophication--Ontario.

abstract:
Relationships between surface sediment diatom assemblages and
lake trophic status were studied in 50 Canadian Precambrian Shield lakes
in the Muskoka-Haliburton and southern Ontario regions. The purpose of
this study was to develop mathematical regression models to infer lake
trophic status from diatom assemblage data. To achieve this goal,
however, additional investigations dealing with the evaluation of lake
trophic status and the autecological features of key diatom species were
carried out.
Because a unifying index and classification for lake trophic status
was not available, a new multiple index was developed in this study, by
the computation of the physical, chemical and biological data from 85
south Ontario lakes. By using the new trophic parameter, the lake trophic
level (TL) was determined:
TL = 1.37 In[1 +(TP x Chl-a / SD)], where,
TP=total phosphorus, Chl-a=chlorophyll-a and SD=Secchi depth.
The boundaries between 7 lake trophic categories (Ultra-oligotrophic
lakes: 0-0.24; Oligotrophic lakes: 0.241-1.8; Oligomesotrophic lakes: 1.813.0;
Mesotrophic lakes: 3.01-4.20; Mesoeutrophic lakes: 4.21-5.4; Eutrophic
lakes: 5.41-10 and Hyper-eutrophic lakes: above 10) were established.
The new trophic parameter was more convenient for management of water
quality, communication to the public and comparison with other lake
trophic status indices than many of the previously published indices
because the TL index attempts to Increase understanding of the
characteristics of lakes and their comprehensive trophic states. It is more
reasonable and clear for a unifying determination of true trophic states of
lakes.
Diatom specIes autecology analysis was central to this thesis.
However, the autecological relationship of diatom species and lake trophic
status had not previously been well documented. Based on the
investigation of the diatom composition and variety of species abundance
in 30 study lakes, the distribution optima of diatom species were
determined. These determinations were based on a quantitative method
called "weighted average" (Charles 1985). On this basis, the diatom species
were classified into five trophic categories (oligotrophic, oligomesotrophic,
mesotrophic, mesoeutrophic and eutrophic species groups). The resulting
diatom trophic status autecological features were used in the regressIon
analysis between diatom assemblages and lake trophic status.
When the TL trophic level values of the 30 lakes were regressed
against their fi ve corresponding diatom trophic groups, the two
mathematical equations for expressing the assumed linear relationship
between the diatom assemblages composition were determined by
(1) uSIng a single regression technique:
Trophic level of lake (TL) = 2.643 - 7.575 log (Index D)
(r = 0.88 r2 = 0.77 P = 0.0001; n = 30)
Where, Index D = (0% + OM% + M%)/(E% + ME% + M%);
4
(2) uSIng a' multiple regressIon technique:
TL=4.285-0.076 0%- 0.055 OM% - 0.026 M% + 0.033 ME% + 0.065 E%
(r=0.89, r2=0.792, P=O.OOOl, n=30)
There was a significant correlation between measured and diatom
inferred trophic levels both by single and multiple regressIon methods (P
< 0.0001, n=20), when both models were applied to another 20 test lakes.
Their correlation coefficients (r2 ) were also statistically significant (r2
>0.68, n=20). As such, the two transfer function models between diatoms
and lake trophic status were validated. The two models obtained as noted
above were developed using one group of lakes and then tested using an
entirely different group of lakes.
This study indicated that diatom assemblages are sensitive to lake
trophic status. As indicators of lake trophic status, diatoms are especially
useful in situations where no local trophic information is available and in
studies of the paleotrophic history of lakes.
Diatom autecological information was used to develop a theory
assessing water quality and lake trophic status.

Finches--Comparative studies.
Carpodacus mexicanus.
Birds--California--Goleta.
Birds--Ontario--St. Catharines.

abstract:
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 comparison, House Finches in St. Catharines, Ontario
(ONT) represented the introduced population.
Interlocality variation in 25 morphometric characters of 100
adult House Finches was examined statistically. Singleclassification
analysis of variance revealed significant
interlocality differentiation in seven characters of males and
nine of females. Females showed differentiation in more limb
elements than males. Analysis of character variation using
discriminant and principal component analysis distinguished
samples on the basis of variation in shape. Compared to CAL, aNT
birds (especially females) had smaller extremities relative to
certain core parts and weight. Females showed similar patterns
of character covariation in each locality on the second principal
component, which suggests that differentiation of the ONT
population may not be solely environmentally induced. Sexual
dimorphism was evident in four charaoters in aNT and five in CAL.
Disoriminant analysis distinguished sex on the basis of variation
in shape. Males possessed a relatively larger flying apparatus and small.er hind limbs than females. The dearee of sexual
dimorphism did not vary sicnifioantly between looalities.
3
Data on reproduotive parameters were oolleoted in 1983 and
1984 in ONT, and 1984 in CAL. In 1984, Bouse Finohes began
breedina approximately three months earlier in CAL than in ONT.
In ONT, there was no sianifioant differenoe in mean olutoh
initiation date between 1983 and 1984. In both looalities most
nests oontained either four or five ea",s, and olutoh size
differenoes between looalites were not signifioant. Seasonal
deolines in olutch size were evident in ONT but not in CAL.
Intralooality variation in e.g weight and size was not related to
clutch size. E",g weiaht showed no seasonal trend in ONT, but
inoreased sianifioantly with breed ina season in OAL. In both
looalities e8'''' weiaht increased sipifioantly with order of
layina in olutohes of four but not in clutohes of five. Eag's in
ONT in 1983 and 1984 were sip.ificantly larser than in CAL in
1984. The modal inoubation period was 13 days and did not vary
sip.ifioantly between localites. In both looalities nestling
weiaht on the day of hatohing was oorrelated to fresh ega welaht.
For muoh of the period between hatohing and 14 days post-hatoh,
ONT nestlinas were signifioantly laraer than CAL nestlings in
terms of weiaht. bill length, bill depth, and manus length.

Ecology--Ontario--Crawford lake.

abstract:
The present study was carried out to test the hypothesis that
photosynthetic bacteria contribute a large portion of the food of
filter feeding zooplankton populations in Crawford Lake, Ontario. The
temporal and spatial variations of both groups of organisms are
strongly dependent on one another.
14
By using C-Iabelled photosynthetic bacteria. the ingestion and
clearance rates of Daphnia pulex, ~. rosea, and Keratella spp were
estimated during summer and fall of 1982. These quantitative
estimations of zooplankton ingestion and clearence rates on
photosynthetic bacteria comprised an original addition to the
literature. Photosynthetic bacteria comprised a substantial portion of
the diet of all four dominant zooplankton species. The evidence for
this is based on the ingestion and clearance rates of the dominant
zooplankton species. Ingestion rates of D. pulex and D. rosea ranged
5 5 -1 -1 - -- 5 - -- 5
from 8.3X10
-1
to 14.6XlO
-1
cells.ind. hr and 8.1X10 to 13.9X10
cells.ind. hr • Their clearance rates ranged from 0.400 to 1.000
-1 -1 -1 -1
ml.ind. hr. and 0.380 to 0.930 ml.ind. hr • The ingestion and clearance
-1 -1 -1 -1
rates of Keratella spp were 600 cell.ind. hr and 0.40 ul.ind. hr
respectively. Clearance rates were inversely proportional to the
concentration of food cells and directly proportional to the body size
of the animals.
It is believed that despite the very short reg~neration times of
photosynthetic bacteria (3-8 hours) their population densities were
controlled in part by the feeding rates of the dominant zooplankton in Crawford Lake. By considering the regeneration times of photosynthetic
bacteria and the population clearance rates of zooplankton, it was
estimated that between 16 to 52% and 11 to 35% of the PHotosynthetic
bacteria were' consumed· by Daphnia· pulex. and Q.. rosea per day.
The temporal and spatial distribution of Daphnia pulex, !.. rosea,
Keratella quadrata, K. coChlearis and photosynthetic bacteria in
Crawford Lake were also investigated during the period of October, 1981
to December, 1982. The photosynthetic bacteria in the lake, constituted
a major food source for only those zooplankton Which tolerate anaerobic
conditions. Changes in temperature and food appeared to correlate with
the seasonal changes in zooplankton density. All four dominant species
of zooplankton were abundant at the lake's surface (O-4m) during winter
and spring and moved downwards with the thermocline as summer
stratification proceeded.
Photosynthetic bacteria formed a 2 m thick layer at the
chemocline. The position of this photosynthetic bacterial J-ayer changed
seasonally. In the summer, the bacterial plate moved upwards and
following fall mixing it moved downwards. A vertical shift of O.8m
(14.5 to 15.3m) was recorded during the period of June to December. The
upper limit of the photosynthetic bacteria in the water column was
controlled by dissolved oxygen, and sulfide concentrations While their
lower limit was controlled by light intensity. A maximum bacterio-
1
chlorophyll concentration of 81 mg Bchl.l was recorded on August 9,
1981. The seasonal distribution of photosynthetic bacteria was

subject: High school students--Social life and customs.

subject: Culture diffusion.

abstract:
This research is a qualitative study of cultural
reproduction and resistance from students'
perspectives. Thirteen teenagers (eight in attendance
in regular high schools and five drop-outs) were
recruited to take part and were involved to varying
degrees through interviews, journal writing, and group
interactive sessions. A purposive sampling design was
used initially to recruit individuals known to the
researcher through contacts in an alternate education
setting. Other participants were recruited throughout
the research phase.
The theoretical aspects are premised on the work
of Paul Willis, Michel Foucault, and Pierre Bourdieu.
The reflexive praxeology of Bourdieu reflects the
position taken as one way of understanding how students
construct and respond to the situations of cultural
dominance they experience in schools. The same
reflexivity is offered for suggestions as to how
teachers can respond to their own position in the
education system.


title: Education, sport and myth in the community of Glengarry, Ontario : the athletic career of Roderick R. McLennan. 260 St. Catharines, Ont. : Faculty of Education, Brock University ;

subject: Sports--Ontario--History. Athletes--Ontario--Biography

abstract:
This study examined how the athletic career of Roderick R. McLennan
contributed to the popularization and subsequent development of Caledonian
games in Ontario during the latter nineteenth century.
Initially, the development of Caledonian games during the 1800s was
examined to provide a contextual framework for McLennan's career. This
investigation revealed that the games emerged from rural athletic events at pioneer
working bees in the first quarter of the nineteenth century to regional sporting
events by the mid-1800s, and finally into annual federated Caledonian games in
1870. Noteworthy primary source material for this chapter included the John
MacGillivray Papers at the National Archives of Canada, the Scottish American
Journal (NY) and the files retained by the Glengarry Sport Hall of Fame in
Maxville, Ontario.
Following the investigation of Caledonian games, McLennan's early athletic
career was studied. Analysis of the Roderick and Farquhar McLennan Papers at
the Archives of Ontario and the newspapers from the period revealed that
McLennan rose to popularity in 1865 through a "Championship of the World"
hammer throwing match in Cornwall and two "Starring Tours".
The next chapter examined the height of McLennan's career through an
investigation of the Roderick McLennan versus Donald Dinnie rivalry of the early
.. n
1870s. It was detennined that the rivalry between McLennan and Dinnie, the
champion athlete of Highland games in Scotland, was a popular attraction and had
an impact on the Toronto and Montreal games of 1870 and the Toronto games of
1872.
Finally, the athletic records established by McLennan during the 1860s and
1870s were investigated. These records were examined through the context of a
media controversy over McLennan's feats that developed in the early 1880s
between two newspapers. This controversy erupted between the Toronto Mail and
the Spirit of the Times.
Caledonian games in Canada have only been briefly examined and a
thorough examination of prominent Canadian figures in this context has yet to be
undertaken. This study unearths a prominent Canadian athlete of Scottish decent
and details his involvement in the Caledonian games of nineteenth century Ontario.


title: Educators' attitudes to philosophies of music education

subject: Music--Philosophy and aesthetics.

subject: Q technique.

abstract:
This study used Q methodology to measure the extent to
which individuals with five educational roles (student
teacher, elementary music teacher, principal, high school
music teacher, and music consultant) held five proposed
philosophies of music education (hedonic, utilitarian,
aesthetic cognitivism, aesthetic formalist, and praxial).
Twenty-seven sUbjects participated in the Q study. These
subjects were a convenience sample based on their
educational role, accessibility, and willingness to
participate. Participants completed a background sheet
which indicated their background in music, and their
responsibility for teaching music.
The sUbjects in this Q study rank-ordered a set of 60 Q
sort items (each item representing a proposed philosophical
position) twice: Sort P to reflect current practice, and
Sort I to reflect the ideal situation. The results of the
sorting procedures were recorded by the participant on the
response page which organized the rankings according to an
approximated normal distribution as required by Q
methodology.
The analysis of the data suggested that the comparison
across philosophical positions was significant and that the
results of the interaction between philosophical position
and educational role were significant, although educational
role alone was not significant. Post-hoc analysis of the
data was used to determine the significant differences
between the levels of the, independent variables used in the
model: philosophical position, educational role, and music
background.
A model of the association of the five philosophical
positions was presented and discussed in relation to the Q
study results. Further research could refine the Q sort
items to better reflect each philosophical position.

abstract:
This paper presents two studies, both examining the efficacy of a computer
programme (Captain's Log) in training attentional skills. The population of interest is
the traumatically brain injured. Study #1 is a single-case design that offers
recommendations for the second, .larger (N=5) inquiry. Study #2 is an eight-week
hierarchical treatment programme with a multi-based testing component. Attention,
memory, listening comprehension, locus-of-control, self-esteem, visuo-spatial, and
general outcome measures are employed within the testing schedule. Results suggest
that any improvement was a result of practice effects. With a few single-case
exceptions, the participants showed little improvement in the dependent measures.


title: Effectiveness of instructional strategies based on schema theory on attention deficit disorder children

subject: Attention-deficit hyperactivity disorder--Ontario--Niagara

subject: Remedial teaching--Ontario--Niagara (Regional

subject: Seventh grade (Education)--Ontario--Niagara (Regional

abstract:
A review of the literature reveals that there are a
number of children in the educational system who are
characterized by Attention Deficit Disorder. Further
review of the literature reveals that there are
information processing programs which have had some
success in increasing the learning of these children.
Currently, an information processing program which is
based on schema theory is being implemented in Lincoln
County. Since schema theory based programs build
structural, conditional, factual, and procedural schemata
which assist the learner in attending to salient factors,
learning should be increased.
Thirty-four children were selected from a random
sampling of Grade Seven classes in Lincoln County.
Seventeen of these children were identified by the
researcher and classroom teacher as being characterized
by Attention Deficit Disorder. From the remaining
population, 17 children who were not characterized by
Attention Deficit Disorder were randomly selected.
The data collected were compared using independent
t-tests, paired t-tests, and correlation analysis.
Significant differences were found in all cases. The Non-Attention Deficit Disorder children scored
significantly higher on all the tests but the Attention
Defici t Disorder children had a significantly higher
ratio of gain between the pretests and posttests.

subject:
Life skills--Ontario.
Occupational training--Ontario.
Human behavior.

abstract:
In the first week of a Job preparation Program
all twelve female members of the class were invited to be
part of a study to determine the effect of Life Skills
training on their behaviour over the twelve-week period of
the program. Six females volunteered and each was
interviewed four times during the Job preparation Program
and once after the program ended. The interviews focused
on three areas of skill deficiency addressed in Life Skills
lessons: their knowledge about themselves and attitude
towards themselves; their interpersonal relationships;
and their problem-solving ability. The participants'
comments over the sixteen-week period of the interviews
were used to decide if the total behaviour of the
participants, (i.e., what they did, thought, and felt)
changed so that each became more effective in satisfying
her needs.
The study suggested that the total behaviour of
three of the six women changed so that they became more
effective in satisfying their needs. The fourth female's
total behaviour changed in only two of the three areas
focused on in the interviews, and the total behaviour of
the fifth and sixth females showed no change.
