The findings reveal that there are many components of the strategic planning process that can assist in the implementation and management of change in the fire service.
Employee Assistance Programs: Suitable Tools For Ontario Boards Of Health, Michael Bragg
Employee Assistance Programs: Suitable Tools For Ontario Boards Of Health, Michael Bragg
MPA Major Research Papers
This paper examines the prevalence of employee assistance programs (EAPs) in Ontario based on a survey of 38 public health units in the province. The findings reveal that only 42 percent of the respondent agencies provide assistance to their employees due to a number of issues associated with the development of these programs, but public health units tend to have a higher level of EAPs in place than the general workforce.
Human Services: The Future Role Of Local Government In Ontario, Stephen Cairns
Human Services: The Future Role Of Local Government In Ontario, Stephen Cairns
MPA Major Research Papers
This paper examines the role of local government in the planning, delivery, and management of human services based on a discussion of provincial programs in Ontario. The findings reveal that local government’s role in human services is being eroded due to provincial initiatives and provincial-municipal agreements that assume greater control by the Ontario government in local activities.
Restructuring Local Government In Ottawa-Carleton, George Vadeboncoeur
Restructuring Local Government In Ottawa-Carleton, George Vadeboncoeur
MPA Major Research Papers
This paper examines the Ontario government’s proposed major changes to the local government of Ottawa-Carleton with respect to the political structure and the distribution of responsibilities. An analysis of three previous studies of regional government in the municipality was conducted. The findings reveal that a two-tier structure of local government is acceptable and the proposed changes would empower the regional government, although some minor changes regarding the delivery of services are required.
The Municipal Role In Child Care – Ontario, Karen Chan
The Municipal Role In Child Care – Ontario, Karen Chan
MPA Major Research Papers
This paper examines the municipal role in child care based on interviews, surveys, workshops, conferences, and focus groups with officials from Ontario municipalities. The findings reveal that the planning and development of human services is shared between the provincial and municipal levels of government but provincial legislation regarding child care must include the appropriate allocation of responsibility to the municipal level in order to ensure that the service is institutionalized.
Paleomagnetism Of Mississippi Valley-Type Ores And Their Paleozoic Host Rocks In Eastern North America, Hairu Pan
Digitized Theses
In this research, paleomagnetic methods are used to study the magnetization characteristics of both ores and host rocks of several major Mississippi Valley-type (MVT) districts, to date their genesis, and thereby to provide paleomagnetic constraints for models of their genesis. In this thesis, research on three major MVT deposits and on a red bed unit has been undertaken. All four of the study areas are situated in or adjacent to the Ouachita-Appalachian orogenic belt in Paleozoic strata.;The Gays River MVT lead-zinc deposit in Nova Scotia is hosted in the Mississippian Windsor Group. A coeval regional hydrothermal event in the area, …
Surface Modifications Of Silicon Induced By Low Energy Reactive Ion Bombardment, Wayne Harold Chang
Surface Modifications Of Silicon Induced By Low Energy Reactive Ion Bombardment, Wayne Harold Chang
Digitized Theses
The effects of low energy reactive ion bombardment of semiconducting silicon material have been investigated by X-ray photoelectron spectroscopy. The residual surface damage induced by a conventional fluorocarbon plasma reactive ion etching of silicon consisted of a uniform fluorocarbon deposited film approximately 4nm in thickness which covered a silicon compound reaction layer. This reaction layer was comprised of silicon oxides, carbide and fluorosilyl species distributed in depth to approximately 2nm. The removal of the residuel surface damage was accomplished by an ozone oxidation plus a wet oxide chemical etching step processing and monitored by surface charge spectroscopy. This residual surface …
Financing Patterns, Resource Scarcity, And New Venture Performance, Robert George Blunden
Financing Patterns, Resource Scarcity, And New Venture Performance, Robert George Blunden
Digitized Theses
This research extends understanding of the determinants of new venture performance by focusing on two previously unexamined factors: financing patterns and resource scarcity. It was designed to examine the relationship between financing patterns and new venture performance and, in particular, to determine if milestone-based, incremental financing patterns, which are becoming more common, are associated with higher new venture performance than other financing patterns. It also examined the relationship between resource scarcity and new venture performance.;Data were collected on forty-one independent new ventures through the venture capitalists who financed them. The researcher reviewed the venture capitalists' files to evaluate the venture, …
Segregation And Oxidation Studies Of Aluminum-Lithium And Aluminum-Magnesium Alloys, Frank Joseph Esposto
Segregation And Oxidation Studies Of Aluminum-Lithium And Aluminum-Magnesium Alloys, Frank Joseph Esposto
Digitized Theses
Auger electron spectroscopy, work function measurements, low energy electron diffraction, nuclear reaction analysis, dynamic/static secondary ion mass spectrometry, thermal desorption spectroscopy, and synchrotron radiation-photoemission spectroscopy have been used to investigate the segregation and oxidation of (111) oriented Al-6.5(at.%)Li and (110) oriented Al-1.45(at%)Mg single crystal binary alloys. The resulting Li and Mg equilibrium surface concentrations are found to be 0.16 and 0.47 respectively. For both alloys, the increase in surface concentration was associated with a decrease in {dollar}\Delta\phi{dollar}. {dollar}\surd 3\rm x\surd 3R30\sp\circ{dollar} and c(2x2) superlattices were observed at the equilibrium surface concentrations for the Al-Li and Al-Mg alloys respectively. This is …
The Myth Of Cartesian Rationalism: An Examination Of Experience In Le Grand, Desgabets, And Regis, Patricia Ann Easton
The Myth Of Cartesian Rationalism: An Examination Of Experience In Le Grand, Desgabets, And Regis, Patricia Ann Easton
Digitized Theses
Recent re-evaluation of the question of the exact role of experience in the Cartesian philosophy has emerged from many quarters. The metaphysical issue of innate ideas has been raised by such scholars as McRae and Miles, and a close examination of the role of empirical enquiry and methodology in Cartesian science have been undertaken by Clarke, Garber, Buchdahl and Laudan, to mention only a few. These recent reappraisals of the role of experience in Descartes's philosophy have been cast mostly in twentieth-century terms with a specific view to concerns of the present.;My research centres on an examination of the philosophical …
Differentials And Determinants Of Fertility Behaviour In Bolivia, David Ernesto Vidal-Zeballos
Differentials And Determinants Of Fertility Behaviour In Bolivia, David Ernesto Vidal-Zeballos
Digitized Theses
This thesis examines differentials and determinants of fertility behaviour for the Bolivian population, focusing on the biological, behavioural, economic, social and cultural factors that directly and indirectly affect reproductive behaviour among the three ecological strata (Highlands, Valleys and Lowlands) and two spatial contexts (Urban and Rural). Moreover, the measurement, description and explanation of these factors at the individual and aggregated levels, and the link between the two levels of analysis has been attempted to examine the interrelationship among proximate determinants, microeconomic variables--cost regulation and motivational cost--modernization and cultural variables, and to understand the differentials in fertility. To do this study, …
A Reassessment Of Locke's Theory Of Cognition Of The External World, Thomas Heyd
A Reassessment Of Locke's Theory Of Cognition Of The External World, Thomas Heyd
Digitized Theses
Locke's Essay concerning Human Understanding has generally been read as primarily concerned with epistemology. In particular, it has been claimed that the Essay attempts to defeat epistemological skepticism, but fails in this enterprise because of the veiling character of Locke's ideas. By way of reexamination of the texts in question I show that epistemological skepticism is not the topic of the Essay, and that there is not sufficient reason to claim that Locke's account of knowledge leads to epistemological skepticism. I argue, moreover, that the motivating topic of the Essay is moral skepticism, and I explain the central role of …
Occupational Exposure To Styrene: Contribution To Hearing Loss, Andrea M. Sass-Kortsak
Occupational Exposure To Styrene: Contribution To Hearing Loss, Andrea M. Sass-Kortsak
Digitized Theses
Prolonged significant noise exposures are well known to result in permanent hearing loss. However, little is known of the contribution of industrial chemical exposures to hearing loss. Information available, both from animal and human studies, raises the possibility that certain aromatic hydrocarbons are ototoxic. The purpose of this study was to assess whether occupational styrene exposure causes hearing loss in a group of workers in the fibre reinforced plastics manufacturing industry. The hearing acuity of 299 subjects was determined, using pure tone screening audiometry, at the beginning of a single workshift and again at the end of the shift. On …
Hydrodynamic And Electrohydrodynamic Instability Of Shear Flows And The Numerical Simulation Of Viscous Droplets, Kenzu Abdella
Hydrodynamic And Electrohydrodynamic Instability Of Shear Flows And The Numerical Simulation Of Viscous Droplets, Kenzu Abdella
Digitized Theses
In this thesis, we investigate three fluid dynamic problems involving various physical mechanisms which exhibit interfacial instability. These problems have wide ranging industrial, scientific and engineering applications.;In the first problem, we investigate the linear stability of the unbounded Couette flow of two fluids separated by a plane interface. The exact dispersion relation is solved asymptotically and numerically to analyze the effects of the four stability parameters of the flow; the ratio of the viscosities, the ratio of the density, the surface tension and gravity. While our results confirm most of the earlier reported theories involving shear flows of fluids of …
Decay Of The Triplet State In A Porphyrin Quinone Molecule, David Donald Fraser
Decay Of The Triplet State In A Porphyrin Quinone Molecule, David Donald Fraser
Digitized Theses
Workers in this and many other labs have been studying photoinduced electron transfer seeking to understand the photochemical processes in photosynthesis. Closely related processes also constitute the basis of some photosensitive tissue diseases and of a wide variety of industrial applications. To study the photophysics unhindered by diffusion, a molecule composed of a freebase porphyrin covalently linked to a p-benzoquinone by an amide linkage was used.;A nanosecond laser flash photolysis apparatus permitted the observation of the porphyrin triplet state decay, with the quinone fully reduced or with it fully oxidized to allow enhanced quenching of the porphyrin triplet via electron …
Brainstem Control Of Three-Dimensional Eye Movements, J Douglas Crawford
Brainstem Control Of Three-Dimensional Eye Movements, J Douglas Crawford
Digitized Theses
This thesis examines the neural mechanisms that generate torsional and vertical eye movements, and how they handle the kinematics of three-dimensional rotations. Three-dimensional eye rotations were recorded in alert monkeys, and the midbrain was studied using single unit recording, electrical microstimulation, and pharmacological inactivation.;The direction of VOR slow phases was usually opposite to that of head rotation, as required for optimal visual stabilization. However, direction errors sometimes occurred because of low gain about a head-fixed torsional axis. This axis was orthogonal to Listing's plane of saccadic eye positions, which suggests that saccades and the VOR share the same coordinate system. …
Multibond Graph Method For Flexible Multibody System Dynamics, Simon Xun-Nan He
Multibond Graph Method For Flexible Multibody System Dynamics, Simon Xun-Nan He
Digitized Theses
In this thesis, a general method for the modelling and simulation of the dynamics of flexible multibody systems undergoing special motion is developed using the multiband graph approach. Until now, bond graph was mostly used to model rigid multibody system dynamics and two dimensional flexible bodies. The multibond graph approach developed in this thesis for the computer-aided modelling and simulation of flexible multibody system dynamics provides an alternative to current computer-aided modelling and simulation of 3-D flexible multibody system dynamics with the added advantage of including a mixed energy domain. The flexible multibody system considered consists of a number of …
High-Resolution Photoelectron Spectroscopy Using Synchrotron Radiation: Ligand Field And Vibrational Splitting And Chemical Effects On Linewidths, Jeffrey N. Cutler
High-Resolution Photoelectron Spectroscopy Using Synchrotron Radiation: Ligand Field And Vibrational Splitting And Chemical Effects On Linewidths, Jeffrey N. Cutler
Digitized Theses
High resolution photoelectron spectra of numerous Group IV, VII and VIII compounds have been recorded using a newly constructed photoelectron spectrometer based on the McPherson ESCA 36 hemispherical analyzer. This spectrometer is designed to make use of the high electron resolution and transmission of the analyzer coupled with the tunability and high photon resolution which is inherent in synchrotron radiation.;For the first time using this instrument, it has become possible to differentiate between three distinct core level broadening mechanisms: vibrational and ligand field splitting and a chemical effect on linewidths. Several I 4d photoelectron spectra of seven different iodine-containing compounds …
Studies Of The Behaviour Of Lipophilic Molecules In Model Membranes: Applications To Amphotericin B And Glycosphingolipids, Katherine S. Hamilton
Studies Of The Behaviour Of Lipophilic Molecules In Model Membranes: Applications To Amphotericin B And Glycosphingolipids, Katherine S. Hamilton
Digitized Theses
Our investigations have focused on two model membrane systems: liposomal amphotericin B and glycosphingolipids as minor components in phospholipid bilayers. Although amphotericin B and glycosphingolipids have very diverse biological functions, studying their respective behaviour and interactions in the context of a lipid bilayer is of prime importance.;The association of amphotericin B with lipid vesicles has proven to be a successful modality of treatment, with an antifungal activity that is closely tied to the physical nature (e.g. vesicle size and lipid composition) of the preparation. Using freeze-fracture electron microscopy, density gradient ultracentrifugation, and differential scanning calorimetry we have characterised the basic …
Predicting Improvement In Psychiatric Patients: A Longitudinal Examination Of Personal And Environmental Factors, Susan M. Ruscher
Predicting Improvement In Psychiatric Patients: A Longitudinal Examination Of Personal And Environmental Factors, Susan M. Ruscher
Digitized Theses
The present study was designed to assess the six-month effects of stress, self-esteem, social competence, coping, social, and family support on the level of functioning and recovery status of 41 depressed and 43 nondepressed psychiatric inpatients. Diagnostic evaluations and level of functioning were based on DSM-III-R (A.P.A., 1987) criteria using the Structured Clinical Interview for DSM-III-R - Patient Version (SCID-P; Spitzer, Williams, Gibbon, & First, 1989). Patients were interviewed and completed self-report questionnaires assessing each of the psychosocial variables at three different times: shortly after hospital admission (Time 1), one (Time 2), and six months after discharge (Time 3).;At Time …
Electroless Reduction Of Gold(Iii) On Pyrite From Chloride Electrolytes, Jay Richard Mycroft
Electroless Reduction Of Gold(Iii) On Pyrite From Chloride Electrolytes, Jay Richard Mycroft
Digitized Theses
The electroless reduction of aqueous precious metal salts on arsenopyrite, galena, zinc blende, stibnite, wolframite and molybdenite was reported as early as 1870. Since this initial work, very little has been reported about the electroless reduction mechanism of gold(III) on pyrite, despite the geochemical importance of this reaction. Recently, surface analytical techniques have been used to study the chemical and morphological characteristics of laboratory-controlled metal deposition. Since the reduction of gold(III) on pyrite is rapid, surface analytical techniques have not been adequate to elucidate the entire mechanism.;On the other hand, electrochemical techniques in conjunction with surface analytical measurements have proven …
Ground Motion Spatial Incoherence, Its Modelling And Effects On Long Gravity Dams, Osman Mohamed Ramadan
Ground Motion Spatial Incoherence, Its Modelling And Effects On Long Gravity Dams, Osman Mohamed Ramadan
Digitized Theses
Seismic design of concrete gravity dams is usually based on a two-dimensional analysis of one monolith, or slice. This analysis provides the basic information but neglects the interaction between adjacent dam monoliths and assumes uniformity of dam section, foundation properties and ground motions along the dam longitudinal axis. While the seismic response of gravity dams has been investigated in considerable detail, the effects of ground motion spatial incoherence on dam response have not been investigated to any great detail.;In this study, dam response to spatially variable seismic excitations is theoretically investigated. Deterministic and random representations of the space-time random field …
Fluid Dynamics Of High-Temperature Bubble And Slurry Bubble Columns, Julie Chabot
Fluid Dynamics Of High-Temperature Bubble And Slurry Bubble Columns, Julie Chabot
Digitized Theses
The present Ph.D. dissertation was focused on the study of the fluid dynamics of high temperature bubble and slurry bubble columns. The study was centred on a system of particular interest for the petrochemical industry, the liquid phase methanol synthesis process, for which very little information is currently available. Emphasis was placed on the study of important gas phase parameters, including the gas holdup, the bubble rise velocity, the bubble chord length and the bubble chord length distribution, which were measured using spherical bulb fibre optic sensors.;The experiments were conducted in a 0.2 m diameter and 2.4 m height carbon …
Suppression Of Eae In The Lewis Rat By Treatment With Neuroantigen-Containing Liposomes, Colleen Sheila Stein
Suppression Of Eae In The Lewis Rat By Treatment With Neuroantigen-Containing Liposomes, Colleen Sheila Stein
Digitized Theses
Treatment of Lewis rats with intracardiac injections of neuroantigen-containing liposomes significantly reduced the clinical severity of spinal cord-induced experimental allergic/autoimmune encephalomyelitis (EAE). Liposomes containing myelin basic protein (MBP), galactocerebroside (GC), or MBP + GC were effective in this respect, while liposomes containing proteolipid protein were not. The best protection was afforded by liposomes composed of whole myelin, as these ameliorated both the acute and relapsing phases of the disease, with a concomitant reduction in CNS pathology.;Neuroantigen-specific proliferative responses of lymphnode cells (LNC) taken from liposome-treated rats were markedly attenuated in comparison to control LNC, while delayed type hypersensitivity (DTH) reactions …
Judgments Of Resource Distributions: The Role Of Long-Term Outcomes, Carolyn L. Hafer
Judgments Of Resource Distributions: The Role Of Long-Term Outcomes, Carolyn L. Hafer
Digitized Theses
Equity theory (Adams, 1965; Walster, Berscheid, & Walster, 1976) proposes that people will perceive a distribution of resources as fair when each person in the relationship receives outcomes in proportion to his/her contributions. While equity appears to be a very important determinant of perceived fairness, inequitable distributions may also be judged fair (Deutsch, 1985). For this dissertation, it was hypothesized that many apparently inequitable distributions are seen as fair because the relationship is expected to be equitable eventually. In such a case, equity is still the underlying principle of distributive fairness, though, on the surface, people appear to be defining …
Stratigraphy And Geochemistry Of Neoproterozoic Iron Formation, South Australia, Kathryn Louise Neale
Stratigraphy And Geochemistry Of Neoproterozoic Iron Formation, South Australia, Kathryn Louise Neale
Digitized Theses
In the southern portion of the Adelaide geosyncline, the Neoproterozoic Yudnamutana Subgroup unconformably overlies older Neoproterozoic sedimentary rocks of the Adelaidean succession. The Braemar and Holowilena iron formations occur locally in the glacigenic Yudnamutana Subgroup at the transitional contact between the basal Pualco Tillite and overlying Benda Siltstone formations, or stratigraphic equivalents elsewhere.;Magnetite and/or hematite and absence of chert typify these iron formations which are associated with diamictite, subarkosic wacke, siltstone and minor carbonate. Diamictites are typically unstratified and have iron-poor ({dollar}{dollar}30 wt.% Fe{dollar}\sb2{dollar}O{dollar}\sb3{dollar}) matrices. The former commonly occur below the iron formation-bearing intervals whereas the latter are intercalated with …

Community Change And Residents' Perceptions Of Industrial Driven Impacts On A Small Town: A Study In Methodology, Catherine Ann Hooey
Digitized Theses
This dissertation examines the perceptions of the effects of community change by residents in a small town. Industries are more frequently locating in smaller communities. The research presented here explores how residents of a small town perceive the effects of selected types of change, including the introduction of a large industry, on their community and their personal lives. A set of methodologies is assessed with regards to its utility in this type of investigation. The role of group membership, social interaction, personal characteristics and the location of an enumeration area (a grouping of households) relative to an event are measured …
Executive Support System Impact Viewed From A Learning Perspective, Betty Mary Vandenbosch
Executive Support System Impact Viewed From A Learning Perspective, Betty Mary Vandenbosch
Digitized Theses
Although learning has been associated with information technology, a theory of how technology, learning and organizational performance are related has never been developed. This dissertation employs a cognitive learning perspective to investigate the impact that executive support systems (ESS) have on organizations by proposing and testing a model of the relationships among these constructs.;The model describes the process by which ESS lead to learning and increased organizational performance. It proposes two types of learning: mental model maintenance in which new information fits into existing mental models and confirms them; and mental model building in which mental models are changed to …
Search Models Of Money, Scott Campbell Hendry
Search Models Of Money, Scott Campbell Hendry
Digitized Theses
This thesis contains three essays studying the emergence of money as a medium of exchange. The search framework used resumes it is difficult for agents to come together in order to trade. The result is a double coincidence of wants problem that can be alleviated through the use of money as a medium of exchange. Much of the recent work studying search models of money is based on papers by Kiyotaki and Wright. This thesis extends their work to make this area of monetary economics more applicable.;Chapter 1 of the thesis introduces a credit instrument into the search model to …
