abstract: Title: The Halton "Deformation": Till: An Application of G.I.S. Basin Analysis Accompanied by a Sedimentological Examination of the Halton Basal Contact, Author: Jarold W. Hibbert, Location: Thode

abstract:
The combined use of powerful computers and Geographic
Information System (G. I. S.) technology has only recently been
utilized as a geological tool in the study of unconsolidated
sediments. G. I. S. is applied in mapping the bedrock topography and
the geometry of the Halton Till in the Toronto region identifying
the technology as an essential component of any basin-wide
investigation.

The bedrock surface exhibits a strong control over the
distribution of the Late Wisconsin aged Halton Till. The wide,
deep Laurentian channel contains thick sequences of Mid Wisconsin
sediments and is capped by a thin veneer of Halton Till. The
highland areas on the flanks of the Laurentian channel contain many
small bedrock channels oriented in a NW/SE trend parallel to ice
flow in the Late Wisconsin. These smaller bedrock channels are
often the sites of thick deposits of Halton Till.

A sedimentological investigation of the Halton Till basal contact in outcrop reveals strong evidence of
underlying sediments into the Halton Till.
Sediment rafts, deformed basal zones in the Halton Till and sheared underlying
sediments suggest that the traditional classification of the Halton
Till as a lodgement complex is incorrect.

A grainsize investigation of the lower 10 meters of the Halton Till supports the outcrop evidence of the incorporation of
underlying sediments into the lower Halton Till. The lithology of
the underlying unconsolidated sediments have a strong control on
the grainsize distribution of the lower 4 meters of the Halton Till.

The geometry of the Halton Till, its sedimentology, grainsize distribution and glacitectonic deformation of underlying units all provide evidence for the deposition of the Halton Till as a
'deformation till'. Present investigations of the Halton Till as
a potential unit for the location of waste disposal sites should
take into consideration the geometry and sedimentology of the till.

G.I.S. is a rapidly expanding field and it will play an important role in the study of Quaternary sediments (particularly aquifers) and the location of future hazardous waste disposal sites
in Southern Ontario.

abstract:
 Bioherm growth within the Edgecliff Member of the Onondaga Formation in the vicinity of Port Colborne, Ontario is represented by a broad low-lying coralliferous mound, trending approximately north-south. The mound displays a progressive pattern of faunal and lithologic succession which can be broken down into four stages. The Basal and Coral-Rich Basal Facies represents deposition in a shallow to deep shelf lagoon, below fair weather wave base and above storm wave base. Stage I of mound development is initiated in response to a slight regression near the top of these facies, corresponding to the deposition of the Transitional Facies, a shoaling upwards sequence reaching above the surrounding substrate. stage II is represented by the colonization and stabilization of the mound by solitary and colonial corals within fair weather wave base. Stage III results in the diversification of the mound upwards into a high energy zone, corresponding to the deposition of the Core Facies. At this time, sea-level remains stable and intermound areas are filled in by the Biostrome, Flank, and Flank/Cap Facies. The final stage, Stage IV represents the termination of mound growth by deposition of a crinoidal cap due to, either a fall in sea-level, or growth of the mound into the surf zone.

 The inferred paleocurrent direction from facies relationships, and a measured coral orientation, suggest currents direction from the southeast to northwest.

 Thus, the Edgecliff Member of the Onondaga Formation in the vicinity of Port Colborne, Ontario represents deposition in a shallow shelf lagoon, and displays evidence for two possible sea-level fluctuations; one near the top of the Basal and Coral-Rich Basal Facies, and the second corresponding the Flank/Cap and Cap Facies, terminating mound development.

abstract:
 The Archean pyroclastic conglomerate studied has six clast types which can be condensed to four clast families based on lithology. The quartz clasts have an average strain of X:Y:Z=1.21:1:0.55 while the pumice clasts have an average strain of X:Y:Z=1.27:1:0.47. The difference is strain between these clast families can be attributed to their different viscosities. The quartz clasts have an assumed viscosity ratio between the clasts and the matrix of unity and are taken to represent the strain in the rock as a whole. The sulphide and black clasts have strain ratios much higher than the quartz because of recrystallization of the sulphide and
cleavage formation effecting the black clasts.

 The sedimentary structure of the deposit and its position between mafic pillow basalts indicate that the deposit is a result of the deposition of a subaqueous pyroclastic debris flow in a proximal environment.

abstract: Title: A Sand-Filled Meandering Channel, Upper Horseshoe Canyon Formation (Upper Cretaceous), Drumheller, Alberta, Author: Suzanne E. Pagani, Location: Thode

abstract:
Three fluvial channels of the Upper Cretaceous
Horseshoe Canyon Formation are exposed at Drumheller
Alberta. The channels are isolated lenticular bodies and
are separated by abundant fine- grained sediment.

One channel appears to be filled to the top with sand and contains large, concave upward surfaces. The other channels contain well defined lateral accretion surfaces and
large scale trough cross-bedding. Associated with the
channel sands are levee, crevasse splay and distal over bank deposits. These channels are interpreted as high sinuosity, suspended lad, meandering channels.

Paleoflow directions measured in the cross-bedded sands indicate paleoflow directions towards the east.

Grain size distribution plots for the sandstones
commonly lack a coarse population of grains transported by
traction. Flow calculations show that the channels were
competent to move grain sizes much larger than those present
within the channels . This leads to the conclusion that the
characteristics of the traction population were strongly
dependant on the supply of coarse material. Shear
velocities in the channels were calulated to range from 3.1 to 9 cm s -1.

The proposeed mechanism for the sand filling of a
meandering channel is through gradual abandonment by chute
cutoff. Maintenance of flow conditions, capable of transporting sand, due to the decrease of depth with discharge, allowed the continued deposition of sand within
the channel. Evidence of scoured surfaces within the
channel indicate that any fines that may have been deposited
were eroded away during flood stages when the meander loop
was reoccupied.

abstract: Title: Sedimentology and Stratigraphy of the Lower Cretaceous Viking Formation, Chigwell Field, Albert, Canada, Author: Indraneel Raychaudhuri, Location: Thode

abstract:
Ongoing regional studies of the Viking Formation (Upper
Albian Stage, Lower Cretaceous) have revealed four regionally
extensive erosional bounding surfaces within the interval.
Examination of twenty-seven Viking cores from the Chigwell
field allowed the nature of the erosional surfaces to be
investigated. The examination of cores also permitted the
sequences of sediments between the erosional bounding
surfaces to be documented. Once documented in a series of
well log and core cross sections, an attempt to interpret the
nature and morphology of the erosional surfaces and the
sediments they envelope was made.

The development of the erosion surfaces is problematic. It is suggested here that relative sea level fluctuations played
a major role in the formation of both the erosion surfaces
and the sediments found at Chigwell.

abstract: Macro-borings and other biogenic structures found in Ostrea glabra valves were examined using a dissecting microscope, SEM and X-radiography. Shells were collected from in situ and transported oyster beds of the Bearpaw-Horseshoe Canyon Formation transition (Upper Cretaceous) at Drumheller, Alberta. Emended diagnoses for Entobia, Talpina and Zapfella were proposed and systematic descriptions of these ichnogenera along with Oichnus were done. Repair blisters and partitions apparently formed by the oyster in response to irritations were also described and interpreted. It was confirmed that statistical analysis could differentiate between round holes drilled by naticids and muricids. It was possible to define fossil micro-environments on the basis of an interpretation of taphonomy and paleoecology considered within the sedimentary context.

abstract:
 The Paleozoic bedrock surface of southern Ontario is dissected by an interconnected system of buried bedrock valleys that are infilled with thick successions of glacial, interglacial and fluvial sediments. These valleys can be several kilometers wide, reach depths of up to 250m and the coarse-grained units are known to host significant local and regional groundwater aquifers.

 Two buried bedrock valleys located near the Niagara Escarpment in the Region of Halton were under investigation in the fall of 1999 for their potential to host additional municipal groundwater aquifers to supply drinking water to the towns of Milton and Georgetown. Detailed logging of sediment recovered from eleven continuously-cored boreholes, drilled within the Georgetown and Milton bedrock valleys, forms the basis for this study. Four distinct facies types were identified within the borehole cores including sand, gravel, fine-grained sediment and diamict (sand-rich, mud-rich and clast-rich). These four facies types were used to subdivide the cores into six stratigraphic units based on textural characteristics and stratigraphic position. These six units form a stacked succession of aquifers and aquitards within the valley infill with two stratigraphic units being identified as potential municipal aquifers.

 The Georgetown buried bedrock valley contains narrow bedrock channel interpreted to have been fluvially incised, lying within a broader flat-bottom valley likely formed by glacial scouring of the bedrock. It is feasible that regional bedrock jointing created a zone of weakness that was later exploited by a drainage network. The valley infill sediments record the approach of the Laurentide Ice Sheet into southern Ontario during the Early to Mid-Wisconsin, and the subsequent overriding of the area during the Late Wisconsin period.

abstract:
 The East South C (E.S.C.) ore zone at the Dickenson Mine, Red Lake, is a major auriferous banded sulphide orebody which cross-cuts sulphide facies banded iron formation (S.F.B.I.F.) near its eastern termination. Pyrite was obtained from sulphide-rich portions of the ore zone as well as from sulphide-poor E.S.C. mineralization not spatially associated with S.F.B.I.F., S.F.BI.F., shear zone hosted mineralization such as the 1492 and F ore zones, and from quartz-carbonate vein mineralization in the South C ore zone. Forty-three pyrite separates from the zones were analyzed by Atomic Absorption Spectrophotometry for Co and Ni, in order to determine the origin of the E.S.C. ore zone. The average Ni and Co content of these pyrites are as follows: S.F.B.I.F.,7.9 and 13.6 ppm respectively; remobilized S.F.B.I.F. 10.3 and 13.6; carbonatized
S.F.B.I.F. 10.9 and 22.6; South C 14.9 and 50.6; 1492 zone 34.1 and 28.4; F-zone 11.2-27.6; sulphide-poor E.S.C. 26.2 and 48.4 and sulphide-rich E.S.C., 17.91 and 16.63.

 High and variable Co values were found to be associated with carbonate-rich samples, irrespective of the type of mineralization and low and similar Co values were found in all carbonate-poor samples irrespective of their origin. Therefore, the Co content of pyrite cannot be used as a discriminant of genetically dissimilar pyrite. The Ni content in pyrite from S.F.B.I.F. is low and constant, while in shear zone and vein mineralization it is higher and more variable. The E.S.C. ore zone has similar values to that found in the epigenetic mineralization, however, a few sulphide-rich samples are similar to those found in S.F.B.I.F., suggesting a bimodal source of sulphide for the E.S.C.. It is proposed that the hydrothermal system which produced the E.S.C., 1492, F and South C ore zones, locally incorporated sulphides from the S.F.B.I.F. to produce the sulphide-rich mineralization found at the eastern extremity of the E.S.C. ore zone.

subject: ore, petrology, wallrock, lake shore gold mine, kirkland lake, paragenesis, alteration, minerals

abstract:
 The Lake Shore Mine has accounted for over a quarter of the gold produced in the Kirkland Lake camp. Petrography suggests that gold is a later phase in the paragenesis of ore minerals. Sulphides precipitated first followed by tellurides and gold. Wallrock alteration
adjacent to the quartz veins was studied by thin section and geochemical analysis. Petrography enabled an alteration facies scheme based on predominant alteration minerals to be established. The alteration assemblages suggest the fluid had a high K and CO2 content, low Na, and reduced S content. Geochemical analysis of these samples confirm petrographic observations and suggests major additions of K2O, SiO2, Rb, Sb and Au to the wallrock, and losses of Na2O, Ba and Zr from the wallrock.

title: Stress Analysis Using Deformation Lamellae in Quartz

subject: stress, deformation, lamellae, quartz, orientations

abstract:
 Orientations of deformation lamellae in quartz and C-axes of quartz grains containing lamellae were measured at seven locations across a gently folded bed of the Oriskany Sandstone, central Pennsylvania. Lamellae so measured have an average inclination of 20°-30° to the basal plane, and are therefore categorized as "subbasal".

 Fabrics of poles to deformation lamellae and corresponding C-axis orientations suggest a paleostress field for the fold which had the arrangement; σ1 bedding parallel, σ3 bedding perpendicular, and σ2 fold axis subparallel. Relative magnitudes of the stresses were given by the condition
σ1 > σ3. σ2 is believed to have varied in magnitude between σ1 and σ3 during fold development.

 Exact timing of formation of lamellae is uncertain. Textural evidence shows that they predate a later generation of compressional and tensional microfractures associated with the deformation. The best explanation is that they formed in early stages of layer parallel compaction when compressive stresses in all zones of the fold were greatest. Stress refraction may or may not have been operative.

Studebaker, Steven M.

subject: freedom, contradiction, trilogy, Jürgen Moltmann, God, spirit, theology

abstract: Jürgen Moltmann's trilogy-Theology of Hope, The Crucified God, and The Church in the Power of the Spirit-is pervaded by the concept of "contradiction." Secondary literature commonly alludes to his theology of contradiction, describing his theology as "dialectical," but the literature rarely analyzes it comprehensively. This thesis seeks to fill this lack. It argues that in Moltmann's trilogy God creates and fosters in the world three different types of contradiction (objective, subjective and active) through three different means (God's promises, his crucifixion, and the work of his Spirit in and through the Church) in order to accomplish his purposes. The inductive sections of the thesis show that contradiction exists in nearly every chapter of each book. The systematic sections show contradiction is central to the main systematic theological topics of the trilogy. Understanding Moltmann's theology of contradiction this way allows for clearer interpretation of his theology as a whole.

subject: depiction, conflict, speech, Christian, Jews, non-Christian, Jesus, Christianity

abstract: There are many factors related to conflict between early Christianity and wider Judaism. I argue that in Acts, Luke employs speech content in speech contexts involving Christian speakers and non-Christian Jewish hearers to advance his belief that Jesus' role and identity, confessed and proclaimed by the early Christians, is the most important factor in these conflicts. My analysis demonstrates that, in his narrative, Luke clarifies that outsiders frequently produce mistaken interpretations of the early Christian movement and that their accusations against Christianity, based on these mistaken interpretations, are false. At the same time, Luke shows how attitudes and decisions regarding Jesus' identity provoke, escalate, and alleviate conflict. The end result of this is that Luke's implied readers are directed to view Christology as the single most important factor involved in conflict between Christian and non-Christian Jews.

abstract:
 This thesis is an initial attempt to shed light on mutual interaction between Coptic and Jewish traditions by demonstrating a Jewish impact on the early stage of the Alexandrian Church as seen in the Coptic Morning Service. It explores the possible influence of the Jewish liturgies and prayers including the writings of the late Second Temple era (200 BCE - 70 CE) on some of the origins of fundamental Coptic rituals. The Coptic Morning Service holds almost identical texts, order of prayers, and, many major Jewish thematic interrelations.

 This study argues for an important lacuna in the spirituality of the contemporary Coptic worshiper. The mystifications that surround many Coptic liturgical components prevent parishioners from praying with understanding (1 Cor. 14:15). The twenty-first century Copt needs a sort of "Halakah" guidance towards their worshipping practices.

 This thesis hopes to offer a potential reconstruction of the early history of the Alexandrian Church through liturgy that could open a new scholarly field of Judeo-Coptic studies.

title: Reimagining Church Leadership for the Canadian Church in the 21st Century from the Doctrine of the Incarnation

subject: reimagining, church, leadership, Canadian, doctrine, incarnation,ministry, congregations

abstract: In a post Christendom Canada, the church finds itself in a place where it must turn to the biblical witness and discern theologically about the course of the church in an ever changing society. This thesis explores passages that speak about the incarnation such as John 1:14, and the Christ Hymn in Philippians (Phil 2:6-11) and points out that the incarnation is a testimony of the missional nature, and work of God. This thesis also expands upon this point to develop an understanding of how the church today can be described as incarnational. The remainder of the study is devoted to understanding the critical role of leadership in cultivating an incarnational church, and developing the incarnational leadership model needed for it. The model explores what it means for a leader to live incarnationally, and provides a framework for how it shapes their life, ministry and congregations.

abstract: Title: Stylolitization Mechanisms, Permeability Barriers and Pressure Solution Generated Cements: Examples from the Lockport Formation (Middle Silurian) of Dundas, Ontario and Nisku Formation (Upper Devonian) of Central Alberta, Author: Craig M. Rice, Location: Thode

abstract:
The study of stylolites found in the Lockport
(Middle Silurian) dolostones and Nisku Formation (Upper
Devonian) limestones has led to the development of two
stylolitization mechanisms. The amalgamation mechanism
(Lockport Formation) forms a stylolite by the amalgamation
of microstylolites through pressure solution of intervening
dolomite. Microstylolites originated as primary "organic"
layers. Dolomitization-stylolitization (Nisku Formation)
forms a stylolite by pressure-dissolution of matrix calcite
against concentrations of dolomite. Dolomite acts as a
stress perturbation that ultimately leads to pressure
solution and stylolitization.

Statistical analysis of Nisku Formation core data
suggests that there is a reversal in the trend of vertical
permeability reduction once a stylolite grows to centimetre-scale.
The most effect permeability barriers are millimetre-
and millimetre to centimetre-scale stylolites.

Cathodoluminescent observations suggest that stylolites generate carbonate cements. The mode of transport
of dissolved material away from the stylolite is by
ionic transfer in porosity and diffusion through intra-crystalline/matrix micrite mediums. Stylolitization is responsible for recrystallization and dedolomitization
textures seen in the vicinity of stylolites. The isotopic
composition of main mineral phases in the Nisku Formation
supports these interpretations.

title: Mount Zion: Yahweh's Presence, Rule, and Eschatological Hope

subject: Mount Zion, Yahweh, presence, rule, eschatological, hope, theology

abstract: Mount Zion has long been a focal point for followers of Yahweh, and central to the cultic practices of the Israelites in the Old Testament. A diachronic examination of the spatial significance of Mount Zion in scripture is undertaken along with its contribution to Zion theology. In the Psalter, Mount Zion is a present reality representing the presence of Yahweh and his established kingdom. Isaiah affirms the inviolability of Mount Zion, concluding that Zion will again be the center from which Yahweh will rule. Scripture depicts Mount Zion as the iconic example of Yahweh's desired place to gather the nations, rule and execute his justice and peace that subsequently spills to the whole earth. In Hebrews, the earthly Mount Zion is seen as an archetype of the heavenly reality. Hebrews reminds its audience of the eternal heavenly city of the living God. In this way, the Mount Zion portrayed in the NT points us to our eschatological hope that recalls the images in the Psalter, Isaiah, and other OT passages. The purpose of this work is to bring a better understanding of the biblical references to "Mount Zion" in relation to its geographical location and the implications for the way we think about Zion in the church today.

title: A Sedimentological Investigation of the Sunnybrook Diamict , Scarborough Bluffs Region, Ontario, Canada

abstract: Title: A Sedimentological Investigation of the Sunnybrook Diamict, Scarborough Bluffs Region, Ontario, Canada, Author: Todd A. Randall, Location: Thode

abstract:
Exposures of Quaternary-aged sediments along the Scarborough Bluffs, near
Toronto, provide considerable information concerning environmental conditions
which existed during the last interglacial-glacial cycle along the southern margin
of the Laurentide Ice Sheet. The present exposures dissect a thick interglacial
deltaic body (Scarborough Formation), overlain by a set of interfingered fine-grained
diamicts (Sunnybrook, Seminary, Meadowcliffe, Halton) and interstadial
sands (Thomcliffe Formation). The depositional origin of the diamicts have been
vigorously debated in the literature, particularly that of the Sunnybrook.

Two facies associations for the Sunnybrook are introduced in this study,
Channel (CFA) and High Facies Association (HFA), based upon: facies and
contact descriptions, and contact geometries. The CFA consists of a thick package
(10-18m) of massive and stratified diamicts, conformably overlain by a succession
(11-25m thick) of finely and coarsely bedded turbidites, and infills topographic
lows within the underlying strata. Silt clast breccia, flow noses, debris flow
deposits, and turbidites, within the CFA, are proof of a subaqueous
resedimentation origin. The HFA is located on the relative highs, away from
channels, forming horizontally-planar contacts with the underlying Scarborough
Formation. The HFA consists of an association of: massive and stratified diamicts, and deformed laminated silts and clays. In addition, the HFA has several
unique characteristics which include: basal clast horizons, an interbedded contact
zone (ICZ), and reverse density loading along the upper contact of the Sunnybrook
with the overlying Lower Thorncliffe Formation.

The proposed depositional model for the Sunnybrook's two facies
associations suggests combined rain-out from suspended sediment plumes and from
ablating ice masses, and resedimentation in a glaciolacustrine setting. As well, a
model of formation for basal clast horizons in the HFA was developed in this
study. A subaqueous interpretation of the Sunnybrook implies the existence of a
high level lake, in the Metro Toronto Region, for the duration of the early and
middle Wisconsin period. Previous interpretations, which suggest subglacial
conditions during deposition of the Sunnybrook and related diamicts, are not
substantiated by the sedimentological and glaciotectonic data of the present study.

title: African-American Pastors and their Effect on the Civil Rights Movement in the United States

subject: african-american, pastors, civil rights, United States, movement, church

abstract: The civil rights movement could have been easily called the civil rights ministry due to its principle leader, the African-American pastor. It was a movement based on the precepts and tenets of the ministry of Jesus of Nazareth. The African-American culture and church are quite often indivisible; this is primarily due to their formation. The leader of the African-American church and culture is often the pastor; they played a principle role in setting the tone and direction of the American civil rights movement. This thesis will show how the African-American pastor's role has been central to the community and how that role has been fluid and adaptive to respond to the adversity and changes within the community and culture.

abstract:
Sandstones and shales of the γ4 Formation, Cloridorme
Group (Middle Ordovician) are well-exposed on the northern
coast of the Gaspé Peninsula, Quebec. The generally structureless,
normally graded, medium to very coarse sandstones
average 26 cm. in thickness and are interpreted as deposits
of subcritical turbidity currents. Associated fine sandstones
and siltstones were deposited from finer-grained turbidity
currents which in some cases were the downcurrent
equivalents of those which deposited coarse sandstones.
Argillaceous sandstone layers containing clasts of siltstone
and shale are the deposits of laminar debris flows.

Facies are organized into four unit types, the most
important of which are sandstone packets and siltstone-shale
interpacket units. Comparison of layer thickness trends in
the actual section with those in a random section constructed
from the same layer thickness population shows that the actual
section is more ordered than expected under random processes.
Layer thickness trends are superimposed on a smallerscale
alternation of thick and thin layers.

Sandstone packets are interpreted as depositional
lobes of a submarine fan. Packets are characterized by multiple or single thickening-upward sequences, with a thinning-upward
sequence at their top representing gradual lobe abandonment.
A channel-fill about 10 m. thick occurs in one packet.
It does not show a thinning-upward trend.

Interpacket units also show dominantly thickening-upward
sequences and are interpreted as lobe-fringe facies.
Switching of submarine fan channels results in changes in lobe
position so that vertical sections are characterized by alternation
of lobe and lobe-fringe facies (outer fan facies association).

Comparison of other parts of the Cloridorme Group with
the γ4 Formation allows their assignment to outer fan, fanfringe
and basin plain facies associations. Submarine fans
grew along the axis of the longitudinal basin rather than
perpendicular to its margin. Opposite palaeocurrents in different
parts of the group suggest that two oppositely-directed
fans were present. Sedimentation rate during Cloridorme
Group deposition was approximately 420 m./m.y.

title: The Dispossessed Inherit the World: A Study of Inclusiveness in the Adoption and Inheritance Metaphors of Galatians 3:23-4:7 and Romans 8:14-25

subject: dispossessed, inheritance, World, adoption, metaphors, Galatians, Romans, Christ

abstract: Paul, the author of Gal 3:23-4:7 and Rom 8:14-25, demonstrates in these two passages a new thing for all believers in Christ-a clear movement from slavery to adoption as sons to the status of heirs. This movement occurs through the process of adoption into God's family and is characterized by inclusiveness regardless of race, socioeconomic status, or gender. This study will explore the promise that the marginalized can participate in a full, new creation inheritance. According to the promise of Rom 4:13, the dispossessed will "inherit the world." This concept of the new creation so clearly seen in Rom 8-expressed also as inheriting the world in Rom 4:13-is critical for correctly interpreting Gal 3:28, framed as it is in a discussion of inheritance and adoption. For this reason, it is of great benefit to study Gal 3:23-4:7 and Rom 8:14-25 together.

abstract: Title: The Depositional History of the Lower Cretaceous viking Formation at Joffre, Alberta, Canada, Author: Karen P. Downing, Location: Thode

abstract:
Detailed core and log correlations have shown that there are three erosion surfaces within the Viking at Joffre, and that each surface is overlain by unusually coarse sediment. The main sand development at Joffre overlies the E2 erosion surface and comprises cross-stratified, medium-grained to pebbly sandstones. The basal portion of this sandstone tends to be glauconitic. This sandstone is interpreted to be the remnant of a shoreface which developed at Joffre in response to a relative lowering of sea level. Evidence for exposure southwest of the shoreface was removed during the subsequent transgression, as was the upper shoreface and
beach. Only the mid to lower part of the shoreface was preserved and blanketted by burrowed marine mudstone.

In total, five bounding surfaces have been defined at Joffre, three of them are demonstrably erosive and the other two are designated as core markers. These bounding surfaces serve to divide the formation into six distinct sedimentary packages which tend to coarsen upward. Viking deposition at Joffre appears to have been controlled by  fluctuations of relative sea level.

abstract: Title: Bedrock Topography and Sedimentary Infill of the Dundas Valley, Hamilton, Ontario, Author: Roger B. Edgecombe, Location: Thode

abstract:
The Dundas Valley of the Hamilton-Wentworth Region forms a prominent west-east re-entrant in the Niagara Escarpment. However as a result of a thick overburden cover little is known of the subsurface geology. In an attempt to define the buried bedrock topography and overlying stratigraphy of the Dundas Valley, a detailed multi-parameter geophysical and sedimentological study was conducted.

New bedrock topography maps based on recently released digital water well data provides details of the regional bedrock morphology, of the western termination of the Dundas Valley, and of surface lineaments on the bedrock surface. Multi-channel seismic reflection profiles provide detailed imaging of the bedrock surface and allow identification of an west-east trending normal fault in bedrock, which shows up to 25m of vertical offset. The coincidence of normal faults and lineaments on the bedrock surface suggests that the lineaments are fault controlled. Differential elevations of the bedrock surface on the north and south sides of the valley also suggests that the Dundas Valley may parallel a normal fault. In addition, the axis of the Dundas Valley coincides with a well defined
aeromagnetic anomaly which delineates a deep-seated fault in the Precambrian basement
(the Hamilton-Presqu'ile Fault). It is, therefore, proposed that original planes of weakness
in the bedrock were probably exploited by glacial and fluvial erosional processes to produce the bedrock form of the Dundas Valley observed today.

Infilling of the valley by Late Pleistocene glaciolacustrine deposits has produced an infill which is dominated by fine-grained lacustrine/glaciolacustrine deposits and coarser-grained fluvial/nearshore deposits. Coarse-grained units have the potential to act as groundwater and contaminant migration pathways. A better understanding of the detailed nature of the infill sediments is necessary to precisely identify and delineate these subsurface pathways.

Transect have provided a geometrical and lithologic framework for the evaluation, modelling and interpretation of geophysical potential field and paleomagnetic data covering the Sudbury
Structure and environs. Through the evaluation of new high resolution aeromagnetic and
radiometric data accompanied by increased gravimetric, paleomagnetic, and rock physical
property surveys, the structure of the Sudbury Igneous Complex and environs have provided new insights into the development of the Sudbury Structure. Analysis of the potential field and paleomagnetic data has determined that: 1) a broad regional magnetic anomaly can be ascribed to the Levack Gneiss Complex subjacent to the Sudbury Igneous Complex (SIC); 2) a zone of hydrothermal alteration associated with the southern contact between the Onwatin and Onaping formations which appears to be spatially related to a deep gravity high; 3) a magnetic high associated with the South Range contact of the SIC produced by the juxtaposition of rocks related to northward directed thrust faulting; 4) the North Range contact of the SIC is a simple layered contact which has undergone strike slip faulting; 5) the Cartier Granite Complex is composed of three distinct fault separated plutons (Birch Lake Granite, Cartier Granite, and Venetian Lake Granite) forming an arc around the SIC; 6) arcuate structures mimicking the North Range of the SIC and the Grenville Front are visible within the granite terrain to the north of the SIC; 7) the regional gravimetric setting of the SIC is heavily influenced by the presence of deep crust, upper mantle related fault and density structures; and 8) the main gravimetric signature associated with the SIC is derived from within 5 km of surface.

abstract: Title: The Sedimentology and Stratigraphy of the Lower Cretaceous (Albian) Viking Formation, Joffre/Mikwan Fields, Alberta, Canada, Author: Lorraine McIntosh, Location: Thode

abstract:
The Joffre/Mikwan field {Lower Cretaceous, Viking
Formation) is a long narrow sandbody encased in marine
mudstones. The sandbody trends northwest-southeast. Four
cross-sections of the area were made, perpendicular and
parallel to the sandbody. The data consisted of 12 cores
and 185 resistivity logs.

Five erosion surfaces are present within the
Joffre/Mikwan fields; E1, E2, CM4, CMS and VE4. Generally,
the erosion surfaces drop stratigraphically northward.
Northward, the erosion surfaces truncate the surface below
or cut into the underlying facies.

There are two erosion surfaces below the main Viking sandstones, E1 and E2. E1 underlies lower shoreface
deposits and E2 underlies middle shoreface deposits, the
main Viking sandstones. These two erosion surfaces were
formed as a result of sea level fluctuations within an
overall transgression. The shorefaces prograded during
stillstands within the transgression. These surfaces, E1
and E2 were formed during the transgression which followed
the relative sea level drop that created the first valley
incision at Crystal.

There are two erosion surfaces above the main Viking
sandbody, CM4 and CM5. Transgressive surface of erosion CM4
was formed when transgression resumed after deposition of
the main Viking sandbody. After this transgression another relative sea level drop created the second incision at Crystal. The transgressive surface of erosion CM5 formed
during the subsequent rise.

This interpretation improves upon the single incision
scheme proposed by Boreen and Walker (1991). It also
suggests a correlation of surfaces CM4 and CM5 with the two
transgressive surfaces of erosion at Crystal.

Studebaker, Steve

subject: work, eschatological, imperative, pastoral, church, spiritual purpose, God's creation, Holy Spirit

abstract:
 This thesis asserts an eschatological perspective that the end of days will come not in apocalyptic destruction, but in transformation. With this theological foundation in view, this thesis draws a deep spiritual purpose in our working lives. This spiritual purpose is God's summons to us to dedicate our vocations to service to the kingdom, now and in preparation for the new creation. This spiritual orientation is the grounding for a critical understanding of a lifetime of work wherein we will strive unceasingly to reflect the image of Christ in our methods and in our demeanour in the workplace. We seek personal sanctification as we respond to God's vocational summons to us.

 This thesis draws a theology of work, founded in the eschatological dimension of transformatio mundi. Work, while often challenging, is not our punishment for Adam's sin. Work is the expression of our essential being. Work is our loving response, in the deepest ethical way, to God's creation. Indeed, this thesis presents the perspective that our daily work is far more than personal and societal economic growth and security. Indeed, this thesis argues that our daily work is more than self-actualization. This thesis asserts that, when it is inspired and equipped by God through the Holy Spirit, our daily labours are not only pleasing to God, but they hold a significant and important eschatological purpose. This thesis asserts the centrality of our work as stewardship of God's resources, and therefore is of critical importance to the pastoral activities of the church.

title: Mistaken Identity: Materialism and Contemporary Evangelicalism

subject: mistaken identity, materialism, contemporary, evangelicalism, church, Christocentric

abstract: Many factors shape the identity of the Evangelical church, some to its benefit, and others to its detriment. This thesis examines the relationship between materialism and Christianity through the framework of Jane Jacobs' work on the existence of two incompatible systems in public and communal life, the commerce and guardian systems. The principles of materialism and Christocentric ecclesiology are shown to belong to these different systems. Joining the missional discussion, this project therefore seeks to correct the influence of materialism on the church's identity by calling the church to a more Christocentric identity. Particular attention is paid to what a materialistic identity and a Christocentric ecclesiology mean for evangelism, church growth, and leadership. Following that discussion, the importance of three theological principles-transformation, incarnation, and service of others-are outlined.

subject: epistemology, Christian, life, Master, story, Agapē-centered,volitional, Jesus, Kingdom

abstract: The purpose of the following is to construct a theological epistemology from analytic religious epistemology and Christian theology. Paul K. Moser's religious epistemology provides an evidentialist account of volitional epistemology centered in agapē. Philippians 2:5-11 and its biblical-theological context grounds the historic and eschatological life of Jesus as the basis and means to participate in agapē. Moser's epistemological framework is reconstructed with the master story to provide a setting for Kingdom practices and imaginary. I argue that knowing the Triune God through agapē centers Kingdom participation. Christians imitate the master story in Philippians 2:5-11 to cultivate agapē through Kingdom participation.

abstract:
Atherosclerosis is a chronic inflammatory disease affecting large- and medium-sized
arteries and is considered the major cause behind cardiovascular diseases (CVD).
Elevated low-density lipoprotein (LDL)-cholesterol and low high-density lipoprotein
(HDL)-cholesterol are considered major risk factors for the CVD. HDL mediates a
variety of atheroprotective actions, many of them involving the interaction with the
scavenger receptor class B, type 1 (SR-B1).
Despite the efforts placed in raising HDL-cholesterol, no improvement has been
achieved in reducing CVD risk, suggesting that other components of the HDL particles
may be responsible for HDL-mediated atheroprotection. One of these may be
sphingosine-1-phospate (S1P).
In this thesis, the role of S1P receptors (S1PRs) in atherosclerosis is explored,
with emphasis in macrophage apoptosis. In particular, the importance of the macrophage
S1PR1 and its role in apoptosis and atherosclerosis was evaluated. We demonstrated that
diabetes exacerbates atherosclerosis development and myocardial infarction in SR-B1
KO/apoE-hypomorphic mice and that treatment with FTY720, a S1PR agonist, protects
against diabetes pro-atherogenic effects. We also show that S1PR1 agonists protected
macrophages against apoptosis through phosphoinositide 3-kinase (PI3K)/AKT, and that
HDL failed to protect S1PR1 deficient macrophages against apoptosis. In vivo,
macrophage S1PR1 deficiency translated into increased atherosclerosis, necrotic core
formation and numbers of apoptotic cells in the atherosclerotic plaque.

BIM deficiency in BM cells was protective against atherosclerosis development
and HDL treatment reduced BIM protein levels in cells exposed to ER stressors,
suggesting that the pro-apoptotic protein may be an important target for HDL in
macrophages.
We conclude that signaling through the S1PRs, in particular S1PR1 is important
in controlling macrophage apoptosis and atherosclerosis development. Our data suggests
that S1PR1 signaling axis and the pro-apoptotic protein BIM play an important role in
mediating HDL anti-apoptotic signaling, however further studies are required to clarify
the interaction between all of these factors.

subject: orienting, register, Day of YHWH, Prophetic, book, Joel, linguistic, worship

abstract:
 This dissertation brings the insights of linguistic discourse analysis, and particularly of Systemic Functional Linguistics (SFL), to bear on the prophetic book of Joel in order to clarify the nature and function of the Day of YHWH in the book. The concepts of register and genre as defined by SFL, along with the related concepts of context of situation, context of culture, and context of text (or co-text), provide helpful tools that both dovetail with the problems and goals of other kinds of synchronic analysis and give new and valuable insights. By applying register analysis to the various passages that deal with the Day of YHWH in the book of Joel, the dissertation identifies the registers of the four sections of the book and compares and contrasts the various registers of each of these sections, making use of this analysis to shed light on the nature and function of the Day of YHWH in each section. Following this is a description of the linguistic register, the context of situation, and the nature and function of the Day of YHWH in the book of Joel as an entire text.

 The Day of YHWH in the book of Joel is a future moment of theophanic intervention, an inevitable day of destruction and salvation. Key to the theology of the Day of YHWH in Joel is the relational orientation of the readers/hearers of the book to YHWH. The book of Joel is thus a communicative act that calls for repentance grounded in worship of YHWH and that promises deliverance from the Day and a glorious eschatological future for those who heed the book's call to proper orientation toward YHWH.

abstract: Title: Fenelon Township A Study of the Evolution of the Physical and Cultural Landscapes, Author: William C. Found, Location: Thode

abstract:
Fenelon Township is located in the middle of
Victoria County, Ontario, in the Kawartha Lakes Region.
It is about 75 miles north-east of Toronto (fig. 1).
Fenelon's rectangular boundary encloses an area of 108
square miles, approximately one-sixth of which is water
surface.

It is the purpose of this thesis to examine the
various landscapes which have characterized Fenelon Township
from the earliest time for which evidence is available to
the present, and to explain the evolution of each successive
landscape. Emphasis is placed in explaining the present
land use pattern.

Chapter I deals with the landscape from Precambrian
times to the end of the Pleistocene glaciation, and Chapter
II explains the subsequent evolution of the climate, soils
and vegetation. Chapter III discusses the development of
the landscape since the arrival of man, from Indian times to
the present. Chapters I to III provide an introduction to
Chapter IV, which gives an account of the 1961 land use
pattern. Finally, a summary and several important
conclusions are stated in Chapter V.

Field work for the thesis was done by car, boat and on foot in July, August and early September of 1951. Extensive
use was made of the soil report for Victoria County, several publications by the Geological Survey of Canada, and aerial photographs.

Personal interviews were an important part of the
field work.

subject: mission, Jerusalem Apostles, authorial, historical, canonical, reconstruction, corpus, epistles

abstract:
 This dissertation argues that the corpus of so-called Catholic Epistles in the New
Testament canon, that is James, 1 and 2 Peter, 1, 2, and 3 John, and Jude, should be
accurately called the Jerusalem Apostolic Epistles. These epistles were written by the alleged Jerusalem Apostles, namely James, Peter, John and Jude. Instead of looking at these writings separately, it is proposed that the mission of the Jerusalem Apostles can be discovered by an authorial, historical, and canonical reconstruction of their epistles if they are studied as a collection. These four canonical authors represented three locations of origin, James and Jude from Jerusalem to the Diaspora Jews, Peter from Rome to the Diaspora Jews of eastern Asia Minor, and John from Asia Minor to the vicinity. The seven epistles were closely knitted together like a web through various kinds of connections and similarities.

 In the process of the canonization of these epistles, we find that the Jerusalem Apostolicity representing the Jewish Christianity played a role in the church in, on the one hand, separating from first-century Judaism, and, on the other, counterbalancing the Gentile Christianity represented by Paulinism. The latter parting of the ways has been in existence from the days of the apostles to even the days of Augustine. The rise of heresies indirectly stimulated the making of creeds and regula fidei.

 Papyrological and patristic evidences show that some of these epistles existed and were in circulation as early as the second century. The Jerusalem Apostles and their writings were recognized, mentioned, quoted, and circulated. There were obstacles for some of the writings of the Jerusalem Apostles to be recognized into the canon. However, in view of the final product and the placement of the canon, all these epistles were compiled together following the Book of Acts to form a single unit of the Apostolos. I propose a canon-logical reconstruction of the Jerusalem Apostolic Theology, and a reading of the Catholic Epistles with literary rearrangement within the Apostolos as part of the discussion of the final canonical product.

 This dissertation concludes with my attempt of an authorial, historical, and
canonical reconstruction of the mission of the Jerusalem Apostles.

abstract:
The prevention of waterborne diseases requires rapid detection of pathogens in drinking water, with an ultimate goal of in-line monitoring in real time. Standard cultivation-based methods are too time-consuming and thus not suitable for this purpose. Many technologies were proposed to achieve this goal, such as ELISA, PCR, FISH, FTIR and flow cytometry. However, they still have limitations of non-specificity, complexity and high cost. Therefore, an optical system is proposed and developed towards the in-line monitoring of bacteria, which combines the advantages of FTIR and micro-flow cytometer for bacterial identification and precise quantification.
The in-line use requires obtaining IR spectra of bacterial cells directly in water, which is achieved using a CaF2 liquid cell. The spectra of a series of bacterial samples are collected and analyzed using principal component analysis for their differentiation. A preliminary study on fabricating a CaF2 concentrator is conducted, in which a novel phenomenon on stress release of silicon nitride film on CaF2 substrate is discovered and studied.
To determine the concentration of bacteria in drinking water, a micro-flow cytometer is built based on a micro-fabricated device that integrates on-chip beam-shaping optics and microfluidic channels. With this micro-flow cytometer and optimized data analysis for counting particles in real time, linearity with correlation coefficient of over 0.99 is achieved for the dependences of throughput on both volumetric flow rate and concentration of sample. With a one-dimensional hydrodynamic focusing, no degradation of the counting efficiency is demonstrated when the focused sample stream expands. The high accuracy of counting makes this micro-flow cytometer a promising candidate for low concentration applications.
Counting of E. coli DH5α cell suspensions in phosphate buffered saline is performed using the micro-flow cytometer. Side-scattered light signals are used to count the E. coli cells. A detection efficiency of 92% is achieved when compared with the expected count from a haemocytometer. It is demonstrated that E. coli can be easily distinguished from beads of similar sizes (2-4µm) as their scattering intensities are different.

Christian Theology

subject: Paul's View, God, Gentiles, Romans, Intertextual, Thematic, Israel, divine

abstract:
 Romans 9-11 has been investigated through varied methods during the past two
decades. One of the most prominent approaches is an intertextual reading of Rom 9-11.
However, most discussions of intertextual studies do not adequately treat the discourse in
Rom 9-11 by closely investigating Paul's discourse patterns and that of his Jewish contemporaries regarding God, Israel, and the Gentiles due to lack of an appropriate
intertextual methodological control. Therefore, this study adapts Lemke's linguistic
intertextual thematic theory as a methodological control to analyze Paul's intertextual
discourse patterns in Rom 9-11. Paul's unique way of using Scripture as one part of his
discourse pattern will be investigated as well. Through the intertextual thematic study of
Paul's discourse in Rom 9-11, we demonstrate the divergence of Paul's viewpoints on some typical Jewish issues, which suggests that the discontinuities between Paul and his Jewish contemporaries are obvious and-sometimes-radical.

 We conclude the findings of our investigation of Rom 9-11 as follows: First, we have adjusted Lemke's intertextual thematic analysis, as an indispensable tool, to analyze Paul's viewpoints of the relationships of God, Israel and the Gentiles in Rom 9-11 within the backdrop of Second Temple Literature. Second, Paul re-contextualizes the Jewish discourse patterns regarding the topics of intercession, Israel, God's promise, God's people, righteousness and law. It can be seen that Paul's discourse patterns share some continuity with his Jewish contemporaries, but the core of his value regarding how to include the Gentiles as God's people stands in a discontinuous relationship with contemporary Judaism(s). Third, this study has demonstrated that although Paul uses Jewish styles of scriptural hermeneutics, and though his discourse patterns resemble some Jewish literature in important aspects, Paul's viewpoint on the relationship of God, Israel
and the Gentiles in Rom 9-11 is dissociated from his Jewish contemporaries in key ways.
In other words, the core value of early Christian discourse has been embedded in Rom 9-
11. Paul's viewpoint on the relationship of God, Israel and the Gentiles takes a divergent
stance away from his Jewish contemporaries since Gentile inclusion is rooted in the Gospel of Christ. Finally, Rom 9-11 not only provides Paul's self-presentation as a Mosaic prophet figure, but also its overall discourse patterns appears as a prophetic discourse: In each section (Rom 9:1-29; 9:30-10:4; 11:1-36) Paul designates his identity or his concerns of lsrael (Rom 9:1-3, 10:1; 11:1-2) before he enters into the argumentation, which demonstrates the relation between Paul's self-understanding and his message in these three chapters; also, the overall discourse pattern in Rom 9-11 resembles a prophetic discourse pattern, which expresses the idea that Paul's self-understanding as a prophetic figure serves to confirm that his word comes from divine authority.

contributor:
Boda, Mark J.
Evans, Paul S.
Christian Theology

subject: Wom(b)an, cultural-narrative, reading, Hebrew, bible, barrenness, ancient, Akan culture

abstract: The barrenness narratives of the Hebrew Bible are not only theological but also cultural in nature. A reading of these texts highlights the fact that in the Hebrew culture, and larger ancient Near Eastern context, childbirth was central to a woman's identity. Since beliefs regarding fertility and infertility are similar in the Akan culture, this dissertation proposes that an African (Akan) perspective may be the bridge needed between the Western readings, in which infertility is not viewed so tragically, and the original ANE context, in which infertility is a shameful and tragic condition for a woman. In addition to examining biological infertility this dissertation will also explore "social barrenness." "Social barrenness" is an original term in this dissertation that seeks to categorise other kinds of barrenness circumstances described within the Hebrew Bible. An awareness of the cultural reality, and varieties, of infertility further elucidates the desperation and lengths to which women in the biblical narratives will go in order to have children. Additionally, an appreciation for the cultural dynamics of the narratives will illuminate the theological message(s) of the story. Since this study employs a cultural-narrative approach, it is appropriate to coin the word "wom(b)an," to underscore the centrality of the womb to a woman's identity in the Hebrew and Akan cultures.

abstract:
Introduction: In Ontario, prior to 1994, planned home birth attended by midwives was a self-paid service. Since the introduction of regulated midwifery in 1994, home birth is a government-funded service, and uses common resources. As such, there is a need to examine the impact that choice of planned location of birth puts on scarce resources. To date, costs associated with planned place of birth in Ontario have not been evaluated.
Objectives: The primary objective is to answer the question: Do planned midwifery-attended home births from the onset of labour cost the Ontario health care system more or less than planned midwifery-attended hospital births from the onset of labour among a comparable low-risk cohort of women? Specifically, this analysis examines the cost of midwifery intrapartum care, from the onset of labour until hospital discharge or the first two days after delivery.
Methods: This cost-analysis used a third-party payer perspective (health services costs) to analyze data from the Ontario Midwifery Program, which included 12, 886 midwife-attended births that occurred between April 1, 2003 and March 31, 2006. Three main sources of information were used to determine unit cost and health care utilization: the Ontario Midwifery Program data (2003-2006); data from the Ontario Case Costing Initiative; and the 2010 Schedule of Benefits for Physician Services. Data was analyzed using an intention to treat approach, i.e. based on planned rather than actual location of delivery.
Results: Hospital birth is more expensive than planned home-birth. Results were significant with a P value =< .001. The median cost from the onset of labour was $995.95 (IQR $995.95 to $995.95) for planned home birth compared to $2118.12 (IQR $1467.12 to $3610.00) for planned hospital birth.
Conclusions: Home birth, a choice that women in Ontario will continue to choose, does not result in costing the Ontario health care system more money.

abstract: This thesis answers the question: Do midwifery-attended planned home births cost the Ontario health care system more or less than midwifery-attended planned hospital births? This thesis examined midwifery-attended births that occurred in Ontario between April 1, 2003 and March 31, 2006 and associated costs that were incurred for both the mother and the baby from the onset of labour until two days following the birth. Since 1994 when midwifery was legislated in Ontario, registered midwives have been providing care to women in both home and hospital settings. While there is general consensus within the midwifery community that home births do not cost the health care system more money, a thorough analysis of costs incurred by midwifery-attended births has not been meaningfully analyzed. Midwifery is the only group of health care professionals providing maternity care that is increasing in size. Given the shortage and the current crisis of maternity care providers, the number of midwives in this province is likely to continue growing. At the same time, a cost analysis of the resources consumed through the provision of maternity care – both at home and at hospital- has not been conducted. This study provides key stakeholders with information regarding resources used and needed and the costs associated with these resources so that resource allocation and planning can be conducted in a responsive manner.


title: Facing Ageism: Toward a Christian Response

subject: ageism, Christian, response, culture, Western culture

abstract:
 Most people in Western culture are inclined, if not obsessed, with the need to maintain
perpetual youthfulness in their actions, attitudes, and image. This cultural ideal is fueled by inner fear as well as age-related stereotypes, prejudice, media messaging, consumerism, and lifestyle strategies. Most of these age-related factors are connected to "ageism," a 1969 term coined by Robert Butler. While the majority of people display various ageist attitudes, often it is without awareness. In a culture that is so profoundly accepting of such a phenomenon, individuals and the church should consider an appropriate Christian response in light of ageism's impacts that include discrimination, loss of self-worth, fear of aging, and judgment of self and others. Once aware of its prevalence and impact, this thesis proposes that the church can respond by raising awareness of ageism and its implications, and modeling a "better way" in its daily life and ministry.

subject: church, amalgamation, theological, rationale, model, community, congregations, God

abstract:
 It is a sad reality but there are more churches every year that find it increasingly difficult to maintain the ministry effectiveness that they employed in years gone by. These struggling congregations face the option of closing their doors, partnering with another church or agency, or merging with another church with the hopes of continuing a ministry presence in their community.

 The merging or amalgamation of churches has been an increasingly popular option that many congregations are exploring but amalgamations are hard work and can be doomed to failure if the congregations involved do not discover the underlying theological reason why their churches failed in the first place. Churches fail when they stop being engaged in the missio Dei. The missio Dei is God's mission in the world to establish his Kingdom "on earth as it is in heaven." The church is a community of people in mission for God.

 Churches that are interested in amalgamation should consider following a model, like the one presented in this thesis, which focuses on understanding and fulfilling the
mission of God within their context.

abstract:
In this report various means of infra-red laser radiation detection were investigated. For the measurement of the energy of pulses of 10.6 μm laser radiation for energies up to 15-20 joules and also for energies up to 200 joules, two pyroelectric detector designs were researched. These two detector designs acted as monitors, using 10% of the beam for detection and allowing 90% to be used for other purposes. Responsivities of as much as 120 mV/J for the 15-20 joule detector and 16.7 mV/J for the 200 joule detector were obtained.

Also three types of photon drag materials, used for pulse shape analysis and power detection were investigated.
InAs and Te were compared to Ge for a possible faster and more sensitive alternative. Also a means of impedance matching and amplifying the output of these rather low sensitivity detectors using a magnetic current probe was analyzed.

Finally an inexpensive and easily constructed container and mount for the 15-20 joules pyroelectric detector was designed along with an attachment to the Lumonics series 100 TEA lasers for ease of alignment with the beam.

abstract: For empirical software researchers, the management of experimental data and results is time-intensive and a significant source of error. As a result, research in this area is often difficult to reproduce, falsify and generalize. Software projects deemed feasible for study are typically of a limiting size and belong to particular domains for which measurement tools are available. We propose a toolkit for data gathering and exploratory modelling in empirical software research. Requirements are derived from issues commonly affecting studies of defect prediction and software evolution. We develop the toolkit by using a prototype-driven approach. The prototype toolkit is used to carry out a case study illustrating its effectiveness and potential for future extension.

title: Inter-National Imag(ining): Canada's Military in Afghanistan

contributor: Political Science - International Relations

subject: Militarization

abstract:
This dissertation examines narratives given by elite foreign policy voices during the Canadian Forces’ involvement in the 2001–2014 International Security Assistance Force (ISAF) mission(s) in Afghanistan.
Part I introduces the topic and outlines the theoretical and methodological ap- proaches used. Part II explores three dominant narratives presented by foreign policy elites: (a) Canada was in Afghanistan to support our NATO allies and to avoid dam- aging our international reputation; (b) Canada was in Afghanistan to fight terrorism and promote security abroad to reduce the domestic threat of terrorism to Canada’s borders; and (c) Canada was in Afghanistan to assist with humanitarian projects to help Afghans. I explore these narratives in light of a long-standing identity myth about Canada’s role in international politics: Canada-as-Peacekeeper. I examine attempts by foreign policy elites to use the mission in Afghanistan to re-militarize Canadian foreign policy and shed the peacekeeper myth.
Part III demonstrates that official war discourses are a result of political negotiations and hegemonic power. Using the Support the Troops campaign, I demonstrate that critics of policy in Afghanistan were silenced using pro-military rhetoric. I argue that the control of foreign policy narratives and the de-politicization of the military as political agents have many problematic effects, most notably that military violence is often cast as an appropriate solution for global political problems. I argue that preoccupation with Canada’s place in the world (i.e. Canada’s international identity) in foreign policy scholarship has under-theorized how narratives about Canadian foreign policy distort and omit particular perspectives. Official discourse on Afghanistan was highly euphemized and politically strategic. The mythologized belief that Canada is a middle-power “helpful-fixer” obscures the actual violence that occurs within military interventions and omits the burden of trauma experienced by soldiers and foreign bodies.

abstract: Title: The Physical and Agricultural Geography of Pelham Township, Author: Jonh B. McClellan, Location: Thode

abstract:
This is a geographical study of the physical and agricultural geography of Pelham Township. It is based largely on field work done in the summer and autumn of 1954. Putman and Chapman have presented an excellent generalized account of the surface features of Southern Ontario. However, in the study of an area as small as Pelham Township, a more detailed account of the physiography is needed. It has been the author's purpose to fulfill this need. A thorough knowledge of the physical basis is prerequisite to a complete understanding of the agricultural geography of an area. Care must be taken, however, unless the physical factor be overemphasized; other factors, especially the historical and economic factors, must be considered in any explanation of the present land use of
an area. It is the author's purpose, in this study, to describe, and account for, the present pattern of land use in Pelham Township. The study is divided into four chapters. The
first two present the physical and historical background of agriculture. They are followed by a chapter on land types and distribution of farm types, and a final chapter of summary and conclusions.

abstract:
The granulite grade McKellar Gneiss and amphibolite grade Nobel Gneiss have been the subjects of detailed geochronologic, geochemical, and petrographic analyses. The Nobel Gneiss, an amphibolite grade gneiss with an average granite composition, has been dated by the rubidium-strontium (Rb-Sr) whole rock dating method and has yielded an age of 1330 +44 Ma with an initial strontium 87/86 ratio of .7033.

The McKellar Gneiss is a homogeneous mafic granulite with heterogeneous portions, one of which has been dated by the rubidium-strontium whole rock dating method and yielded an age of 1241 +12 Ma
with an initial strontium 87/86 ratio of .7034.

The age obtained for the Nobel Gneiss is interpreted as the time of emplacement. The age obtained for the McKellar Gneiss is interpreted as the time of granulite grade metamorphism.

In addition, eight samples from a shear zone which has, in part, been retrograded from granulite facies to amphibolite facies, have also been studied to determine the effects of retrograde metamorphism on the
Rb-Sr isotopic system and on the overall chemical and mineralogical system. Analytical results indicate the introduction of water and possible chemical homogenization of the rocks involved in the shearing event.

Kitai, R.

subject: digital, moments, error, characteristics, analyzer, computer, register, voltage, frequency, multipliers

abstract:
A portable special purpose computer (s.p.c.) is described which provides decimal readouts of the first four moments of a fluctuating voltage v on four separate registers. A fifth register provides a readout of the measuring time which can be within the range 10 ms. to
30 Hrs. The s.p.c. can be switched to another mode which provides a measure of the cumulative amplitude distribution of v within sixteen positive and negative levels. Salient characteristics of the s.p.c. are as follows:
(a) There are no low frequency limitations. The upper frequency limit, established by error considerations, is about 5 kHz with 99.73% confidence that the error is within 1%.
(b) At the end of the measuring time T, all the four moments are immediately available in magnitude and sign.
(c) The outputs can be available in any code, the only change necessary being in the code of the counting readout registers.
(d) All computations for a sample are completed before the next sample arrives so that programming and unnecessary storage facilities are eliminated. The voltage input v is rectified and sampled systematically by an equi-interval a.d. converter. The samples, together with the sign bit, are fed into special purpose digital multipliers based on a
"weighted feed" principle. The outputs from these multipliers, with the sign bit, arc fed to accumulators via parallel adders for each of the moments. The overflows of these accumulators are shown to be contributions to the various moments and are fed to the decimal display registers. Direct computation of the standard deviation (σ) of the input, from
measured first and second moments has also been investigated. A theoretical analysis of the various errors which occur in such an s.p.c. has been made. Results indicate that for most signals the overall error is within 1% for all four moments. Finally, the development of a universal arithmetic cell, for use in iterative and near-iterative arrays, is reported in this thesis. It is shown that use of such arrays in the arithmetic units of the
s.p.c. can lead to a considerably simplified design.

abstract: Title: X-Ray Crystal Structures of Xe(II)-N and Xe(II)-O Bonded Compounds, and the Synthesis of OTeF5 Derivatives of As(III) and Sb(III), Author: Barbara A. Fir, Location: Thode

abstract:
The chemistry of xenon(II) has been extended by the low-temperature X-ray
structure determinations of the Xe-N bonded adduct salts, HC≡N-XeF+AsF6-,
CH3C≡N-XeF+AsF6-·HF, (CH3)3CC≡N-XeF+AsF6-, s-C3F3N2N-XeF+AsF6-·2.5BrF5,
C5F5N-XeF+AsF6-·2.5BrF5, and F5TeN(H)Xe+AsF6-, and the Xe-0 bonded compounds,
F5ChOXe+AsF6- and Xe(OChF5)2 (Ch = Te, Se).

The thermally unstable Xe-N bonded salts represent classes of compounds in which xenon(II) is directly bonded to formally sp-, sp2-, or sp3- hybridized nitrogen atoms. The R-C≡N-XeF+AsF6- (R = H, CH3, (CH3)3C) salts were synthesized by the low-temperature reaction of the nitrogen base with XeF+AsF6- in HF. The C5F5N-XeF+AsF6-·2.5BrF5 and F5TeN(H)Xe+AsF6- compounds were prepared by the reaction of the N-protonated bases with XeF2 in BrF5 and with XeF+AsF6- in HF, respectively. The s-C3F3N2N-XeF+AsF6-·2.5BrF5 salt was prepared by the direct interaction of s-C3F3N3 with XeF+AsF6- at room temperature and subsequent recrystallization from BrF5. The covalent nature of the Xe-N bonds was observed to increase in the order: s-C3F3N2N-XeF+AsF6-·2.5BrF5 (2.316(6) Å) <
C5F5N-XeF+AsF6-·2.5BrF5 (2.287(7) Å) < HC≡N-XeF+AsF6- (2.235(3) Å) <
(CH3)3CC≡N-XeF+AsF6- (2.212(4) Å) < CH3C≡N-XeF+AsF6-·HF (2.179(7) Å) < F5TeN(H)Xe+ AsF6- (2.044(4) Å), indicating that s-C3F3N2N-XeF+ AsF6-·2.5BrF5
contains the most ionic Xe-N bond in this series. It was also observed that as the
covalent nature of the Xe-N bond increases, the Xe-F bond becomes more ionic. The Xray crystal structures of HCNH+AsF6-, F5TeNH3+AsF6-, and F5TeNH2 were also
determined and provided comparisons with those of HC≡N-XeF+ AsF6- and
F5TeN(H)Xe+AsF6-, respectively.

The X-ray crystal structures of the XeOChF5+AsF6- salts have been determined and are isostructural and disordered. The structure of Xe(OSeF5)2 is in agreement with a previous structure report, but is now assigned to the correct space group. The single crystal X-ray structure of Xe(OTeF5)2 was determined for the first time and contradicts an earlier published cell determination of this compound. The structures of XeOChF5+AsF6- and Xe(OChF5)2, which are analogs of XeF+ and XeF2, respectively, confirm that the OChF5 groups have lower electronegativities than F. When compared with the structure of F5TeN(H)Xe+AsF6-, which is isolobal with XeOChF5+AsF6-, it was determined that the relative electronegativities of these groups, and subsequent Lewis acidities of the cations, F5TeN(H)Xe+, XeOChF5+, and XeF+, increase in the order: F5TeN(H) > OSeF5 > OTeF5 >F.

Local density functional theory (LDFT/DZVP) calculations which were done for F5TeN(H)Xe+AsF6-, F5TeNH3+AsF6-, F5TeNH2, and XeOChF5+AsF6-, reproduce the structures and have been used to assign their vibrational spectra. Only the calculated vibrational spectra for XeOChF5+AsF6- are discussed in this Thesis.

The OTeF5 chemistry of As and Sb has also been extended by the syntheses and detailed structural characterizations by 19F and 125Te NMR spectroscopy and by Raman spectroscopy of the new pnicogen anions, Pn(OTeF5)4-(Pn = Sb, As), as their N(CH3)4+ and N(CH2CH3)4+ salts. The As(OTeF5)4- anion was found to be thermally less stable in CH3CN and SO2ClF solvents when compared to the analogous antimony anion. Both anions have trigonal-bipyramidal AX5E VSEPR geometries with two equatorial and two axial OTeF5 ligands that undergo intermolecular exchange in solution by Berry pseudorotation. However, the exchange could not be slowed down sufficiently on the NMR time scale to observe separate environments due to the freezing points of the solvents used. An equilibrium was also observed to occur between Sb(OTeF5)4-, Sb(OTeF5)3, and OTeF5- in CH3CH2CN solvent. All attempts to crystallize Sb(OTeF5)4- were unsuccessful and produced the less soluble, but novel, Sb(OTeF5)5 2- anion instead, whose preliminary disordered X-ray crystal structure is reported in this Thesis.

subject: tide-dominated, shoreface, deposits, Milk River Formation, Southern Alberta, sandstones, floodplain, petrographic

abstract:
 Several sections of the Milk River Formation were measured and studied in detail at Writing on Stone Provincial Park in Southern Alberta. The observed vertical facies succession consists of, from base to top:
1) interbedded, sharp-based sandstones and bioturbated shales; 2) dominantly swaley cross-stratified sandstones; 3) dominantly cross-bedded sandstones;
4) non-marine shales and various thin sandstone and lignite interbeds;
5) local, non-marine cross-bedded sandstones.

 The sharp-based sandstones have been episodically emplaced on top of offshore muds. The dominantly swaley cross-stratified sandstone is a storm-dominated shoreface deposit in which fairweather deposits (eg. medium
scale cross-bedding), are rarely preserved. The cross-bedded sandstones record deposition in tidally-influenced estuaries which cut into beach and shoreface deposits. The section is capped by vertically accreted muds and thin lignite seams which represent floodplain and terrestrial deposition landwards of the strandline. The non-marine cross-bedded sandstones are
local representatives of fluvial channel deposits.

 Paleoflow directions measured in the cross-bedded sandstones indicate that the regional strandline was oriented southwest - northeast at Writing on Stone.

 Petrographic analysis of the swaley cross-stratified and cross-beddedm sandstones indicate that they are Subarkoses. A definite upward coarsening trend from fine to medium grained quartz is observed in the main sandstone body.

title: An Adaptive Control Algorithm for a CNC Milling Machine

Tlusty, J.

subject: adaptive, control, algorithm, CNC, Milling, machine, software, Time Base Generator

abstract:
 The purpose of this project was to develop an Adaptive Control Algorithm for a CNC milling machine. The milling machine is controlled by a 2100A Hewlett Packard mini-computer. The Adaptive Control Software has to operate in unison with an already available Numerical Control Software. Both these programmes are stored in the computer and the computer operates on them with the aid of the interrupt pulses received from the Time Base Generator located in the Controller.

 The Adaptive Control Software should be capable of optimising the milling process, that is enabling the milling machine to operate at the highest feed-rate without violating or overriding the maximum permissible values of the horizontal force and torque acting on the cutter. These maximum values of the force and torque are determined from the tool strength and capacities of the servo drives and spindle motor. Further, the machine should be able to arrive at the above feed-rate in the shortest possible time interval without causing cyclic variations in the feed-rate which could lead to an unstable system. The programme should be able to obtain ten samples of the parameters per
revolution of the spindle. The feed-rate thus obtained (after comparing with the maximum and minimum feed-rates of the machine and making any corrections, if necessary) should be stored in a memory location accessible to the Numerical Control Programme. The instantaneous values of the force and torque are transmitted to the computer via the transducers attached on the spindle of the machine and the Analog-to-Digital Processor, therefore, the Adaptive Control Software will have to communicate with the Analog-to-Digital
Processor in order to receive the values of the forces and torque. Thus the above mentioned requirements will have to be met by this piece of software. With this end in view, the following algorithm was developed.

 The algorithm consists of two portions, namely,
the Data Reading Routine and the Policy Routine. The former accepts the two horizontal forces (which are phase shifted by 90°) and the torque acting on the cutter by communicating with the Analog-to-Digital Processor. However, all these three parameters are received through the same channel from the Analog-to-Digital Processor as such a method of identifying the variables was necessary. For this purpose, the Data Reading Routine consists of software
capable of communicating with the Analog-to-Digital Processor at time intervals of 10 m.sec. and receiving the data in a digital form, decoding the input and ascertaining which input parameter was received. The Policy Routine has two modes of operation viz., the constraint and optimizing modes. This routine ascertains the critical error and arrives at the new feed-rate depending on the Policy used. After checking the value of this feed-rate with the maximum and minimum feed-rates available on the machine (and corrections made if necessary), the suitable value of this feed-rate is stored in a memory location accessible to the Numerical Control programme. This gives the general structure of the Adaptive Control Algorithm developed in this project.

title: Fluid Inclusions of Auriferous Quartz Veins from Harrigan Cove, Nova Scotia

subject: fluid, inclusions, auriferous, Quartz, veins, Harrigan Cove, bedding, arsenic

abstract:
 The Meguma Group is situated in the southeastern and southwestern regions of Nova Scotia. The Meguma Group is divided into two formations: the Goldenville and the Halifax.
Both formations are comprised of A and E divisions of the Bouma sequence. Thus, the Meguma Group is a turbidite deposit. Auriferous quartz veins strike parallel to bedding and
occur between the lower Bouma cycle's E division and the overlying Bouma cycle's A division. The development of bedding-parallel veins was due to hydraulic fracturing of the Bouma units.

 The bedding-parallel quartz veins were emplaced at low temperatures, from 260°C to 300°C. The fluid which precipitated the gold-arsenopyrite-quartz veins consisted of a divalent cation salt species (MgCl2) and hydrosulphide ligands which were the main complexing agent of gold.

 Gold was precipitated due to the reduction of sulphide
ligands as they came into contact with the organic-rich slates of the E division of the Bouma sequence. Sulphide reduction was not complete, thus a large concentration of gold remained
in solution later to be precipitated with arsenic in arsenopyrite.

McCann, S. B.
Geography and Geology

subject: terrain, disturbances, tracked vehicle movement, diamond, drilling, south Central Keewatin

abstract:
 The movement of diamond drills by tracked vehicles and drill trailers in south Central Keewatin was studied during the summer of 1980. Tests of the physical ground strength showed that the ability of the terrain to resist disturbance from tracked vehicle operations
depended on two main physical factors: the type of surficial material and the presence of water. Moisture contents varied throughout the summer so that the response of till and peat to compression and shear was not constant. As the summer proqressed, the increasing depth of thaw and gradual surface drying caused strengthening of both major types of surficial material. As a result, vehicle trafficability gradually increased throughout the summer. While surface rutting increased the depth of thaw compared to an undisturbed site, especially in peat, after the first few weeks of the thaw this had little apparent effect on vehicle trafficability. In many cases the vehicle disturbance was largely aesthetic giving the impression that the terrain disturbance was much more serious than it actually was.

 Although the load distribution of the vehicle tracks concentrated much of the longitudinal stress directly beneath the bogie wheels, in most cases the performance of the tracked vehicle itself was adequate. However, problems caused by the drill trailer wheels resulted in unnecessary mechanical strain on the vehicles and created marked increases in terrain disturbance.

abstract: Title: Late Quaternary Climatic Reconstruction Using the Deep-Water Coral Desmophyllum cristigalli, Author: Jodie E. Smith, Location: Thode

abstract:
In 1978, the Bedford Institute of Oceanography dredged dead specimens of the
solitary, deep-water, ahermatypic coral Desmophyllum cristigalli from the top of Orphan
Knoll, at a depth of 1700 m. The collection lay unstudied until last year. Dating of
several individuals by uranium- thorium and 14c shows that the retrieved corals ranged
in age from 70,000 to 4,000 y BP. One especially large specimen lived from 12,000 to
11,000 y BP. Detailed analysis of the  𝛿18O stratigraphy of this long-lived coral shows
that the Younger Dryas climatic event is preserved as an abrupt shift of >2 per mil,
which suggests a profound change in the saline circulation. It also supports the theory
that massive ocean-atmosphere reorganizations trigger glacial cycles - specifically, in
the North Atlantic, via the shutdown of the Gulf Stream 'heat conveyor'. Estimations of
coral-growth rates give a good indication of the rapidity of the Younger Dryas onset: it
is possible that the transition from interglacial to glacial conditions may have occurred
with 15 years. Many climatic reconstructions to date have been based on the
foraminiferal record, but solitary corals are likely to be far superior recorders of
paleoenvironmental conditions because of their immunity to bioturbation and largescale
transport.

abstract: Title: The Depositional Environment of the Queenston Formation in Southern Ontario, Author: Paul J. Brogly, Location: Thode

abstract:
The Queenston Formation has been interpreted as a
non-marine deltaic deposit since the turn of the century
because of its apparent lack of fossils, and evidence for
subaerial exposure. The source of the sediment was interpreted
to be an orogenic zone in New York or Pennsylvannia.

Features such as gypsum nodules and limy siltstones
were interpreted as being secondary. However, petrographic
studies have found that the siltstones contain marine fossils
and some gypsum nodules have inclusions of halite. Moreover,
the fine sand grains in the mudrock are not aeolian. Paleocurrents
indicate that the source of the sediment transport
was generally north-south not east-west. The siltstone and
limestone interbeds are flat based, graded, and show no
evidence for channeling. Some beds also contain large escape
burrows.

It is proposed that the Queenston Formation was
deposited as a supratidal; mudflat that was regularly flooded
by the sea. The mud could have been transported by longshore
drift from a river somewhere towards the north, as the
paleocurrents in the Queenston mimic major tradewind patterns
for the Late Ordovician.

abstract:
Spectrographic methods have been used to investigate
the distribution of some minor elements in a suite of rocks from the Loon
Lake pluton in southeastern Chandos Township, County of Peterborough,
Ontario, Canada. The rocks studied represent a calc-alkalic series.
The elements under investigation include Be, Ga, Cr, Ti, Li, Ni, Co,
Cu, V, Zr, Mn, Sc, Y9 Sr, Ba, Rb, and Fe. Their abundances are compared
with those determined by other analysts, in particular S.R.
Nockolds and R. Allen. The probable host minerals are also considered.
Cr, Ti, Ni, Co, V, Mn, and Fe generally are enriched in the basic
rocks whereas Rb is generally enriched in the granitic rocks of the
series. Fairly even distributions are shown by Ga, Cu, and Y, and no
clear trends are indicated for Li, Zr, Sr, Ba, Be, and Sc.

abstract:
Tangent oil field in northwestern Alberta has been
formed by a structural trap, created by the downthrown block
of a Graben, combined with porosity created by the
dolomitization of Wabamun limestone.

The dolomitization fluids have migrated from the
underlying Winterburn formation, via fractures, up into the
Wabamun. Well 6-32-80-23W5 is the focus of this study as it
contains a complete sequence from dolomite at the base of
the Wabamun up through a transition to limestones at the top
of the Wabamun. Cathodoluminescence and petrographic
analyses of the dolomites and the transition from dolomite
to limestone has revealed 5 dolomite types; diffuse
microcrystalline dolomite, mosaic dolomite with associated
porosity, and without associated porosity, dolomite which
replaces calcite fracture fill and dolomite related to
pressure solution. These analyses have also revealed the
following paragentic sequence for the five dolomite types
1) microcrystalline dolomite 2) dolomite related to pressure
solution 3) dolomite replacement of calcite fracture fill
4) mosaic dolomite with and without associated porosity.

the rate of widening of the pits formed is dependent on the defect
causing the pit while the pit shape is governed by the HCl in the etchant.
