An Investigation Of Strategic Planning And Organizational Change: Halton Regional Police Service, Laurie Mcginn
An Investigation Of Strategic Planning And Organizational Change: Halton Regional Police Service, Laurie Mcginn
MPA Major Research Papers
This paper examines the strategic planning process used by the Halton Regional Police Service to assess its effectiveness in terms of counteracting staff resistance to change. Case studies of the process that was used in 1991 and repeated in 1995 were conducted. The findings reveal that the working philosophy of strategic planning would be better served by fully recognizing and anticipating employee resistance to change within the strategic planning process and developing solutions to help overcome its effects.
Gta Reform: City Of Burlington – Identification And Analysis Of The Process Used By The City To Evaluate The “Golden” Report, Mickey Frost
Gta Reform: City Of Burlington – Identification And Analysis Of The Process Used By The City To Evaluate The “Golden” Report, Mickey Frost
MPA Major Research Papers
This paper examines the policymaking process used by local governments in order to determine whether the rational or incremental model of decision-making is most evident. A case study of the process used by the City of Burlington in response to recommendations made by the GTA Task Force concerning the City’s governance was conducted. The findings reveal that the policymaking process in Burlington was reflective of both models of decision-making, but elements of the incremental model and persuasion were more evident than the problem solving that is associated with the rational model.
Interorganizational Networking In The Local Government Sector: Case Study Of The Municom Network, Geoffrey Singer
Interorganizational Networking In The Local Government Sector: Case Study Of The Municom Network, Geoffrey Singer
MPA Major Research Papers
This paper examines the potential implications of information and communication technologies on interorganizational relations in the local government sector based on a case study of the Municom Network, which was designed to electronically link Ontario municipalities. The findings reveal that the Municom Network could be an important addition in strengthening interorganizational relationships in the future, as it provides a number of useful tools for direct communication, it is an efficient and powerful means of keeping municipal practitioners updated on events that affect their organization, and it serves as a central repository of municipal information.
The Effects Of Retinal Eccentricity On Prehension And Perception, Kelly Jane Murphy
The Effects Of Retinal Eccentricity On Prehension And Perception, Kelly Jane Murphy
Digitized Theses
The effects of retinal eccentricity on prehension and on the perception of object dimensions was investigated. Human subjects reached out and grasped different sized objects viewed at different peripheral positions along the horizontal and vertical meridians. The sensitivity of visuomotor grip scaling to object width was compared with visuoperceptual judgements about object width.;When retinal eccentricity was varied in the temporal field, along the horizontal meridian, it was found that reaches in peripheral vision were slower and exhibited longer deceleration periods relative to reaches in central vision. Further, the amplitude of the grasp, though scaled to object width, increased as object …
Frege On Indexicals: Sense And Context Sensitivity, Richard Charles Devidi
Frege On Indexicals: Sense And Context Sensitivity, Richard Charles Devidi
Digitized Theses
Indexical expressions--e.g., 'I', 'here', 'yesterday', 'this', etc.--pose a serious challenge for a Fregean theory of meaning. A Fregean theory holds that the meaning of an expression is its sense, and that this sense determines the reference of the expression independently of context. The most notable feature of indexicals, however, is their sensitivity to context. David Kaplan and John Perry argue that there can be no Fregean solution to this issue. They assume (falsely) that the Fregean sense of a singular term is given by a definite description, and argue that this picture cannot work. Kaplan and Perry advance a theory …
Explaining Adoption Patterns Of Process Standards, Philip Paul Gunby
Explaining Adoption Patterns Of Process Standards, Philip Paul Gunby
Digitized Theses
This thesis investigates the adoption of process standards and consists of an introduction, a literature review, two theoretical chapters, a case study, and a conclusion.;The first theoretical chapter presents a model which examines equilibrium adoption patterns. The model incorporates heterogeneous agents who repeatedly choose which process standard to adopt. The agents' decisions are affected by economic processes within as well as outside, the market. In contrast to the usual results of the literature on competing standards, inefficient equilibria are far less prevalent in this model. Interestingly, small changes in parameter values can have a large impact on the characteristics of …
Determinants Of Migration: Inter-European Migration, 1950-1989, Sven Mikael Jansson
Determinants Of Migration: Inter-European Migration, 1950-1989, Sven Mikael Jansson
Digitized Theses
It is commonly assumed that governmental regulations determine the flow of international migration streams. Time-series techniques are used to analyze the migration flows to Belgium from France, Germany, Italy and the Netherlands in the post-war period 1950-1989 in order to estimate the impact that the migration policy change in 1968 had on these flows. A survey of the predominantly cross-sectional migration literature revealed that substantial contradictions are reduced when studies are separated according to their power to detect the significant push and pull factors. The preliminary findings for the time-series analyzed indicated that these series required differencing once before achieving …
The Nature Of Status In Sport Teams, C Shanthi Jacob
The Nature Of Status In Sport Teams, C Shanthi Jacob
Digitized Theses
Status--the importance/prestige which is possessed by or accorded to individuals by virtue of their position in relation to others--plays an important role in group dynamics (Shaw, 1981). In the sport sciences, however, research on this concept is minimal. Thus, three studies were carried out to examine the nature of status among athletes in sport teams.;Studies 1 and 2 examined the relationship of the perceptions of status attributes and status rank to cohesion. Canadian (112 intercollegiate and 64 secondary school) and Indian (47 intercollegiate and 62 secondary school) athletes were tested.;The methodology adopted in Studies 1 and 2 were similar. In …
Baptists And Business: Central Canadian Baptists And The Secularization Of The Businessman At Toronto's Jarvis Street Baptist Church, 1848-1921, Paul Robert Wilson
Baptists And Business: Central Canadian Baptists And The Secularization Of The Businessman At Toronto's Jarvis Street Baptist Church, 1848-1921, Paul Robert Wilson
Digitized Theses
The challenges to the faith of the Baptist businessman exerted by the arrival of a business-dominated culture in the last half of the nineteenth and early twentieth centuries have been largely ignored by Canadian historians. As the Protestant religious minority with the strongest doctrinal emphasis on separation from the world through the application of a strict moral code, Baptists provide the historian with an excellent case study for analysis of the sectarian Protestant response to social and cultural change. One might expect that the "otherworldly" perspective held by Baptists afforded considerable resistence to the secularizing effects of the materialistic social …
Spectroscopy Of Unstable Molecules, Hafed Ashur Bascal
Spectroscopy Of Unstable Molecules, Hafed Ashur Bascal
Digitized Theses
The {dollar}\rm B\sp2\Sigma\sp{lcub}+{rcub}{dollar} ion-pair excited states for the unstable group IIB metal monohalide radicals have acquired eminence as the upper levels for the potentially important blue/green lasers. In this work, the metal monohalide radicals were produced by exciting a corona excited electrical discharge in a supersonic gas expansion. The ion-pair-valence {dollar}\rm B\sp2\Sigma\sp{lcub}+{rcub}\gets X\sp2\Sigma\sp{lcub}+{rcub}{dollar} transitions for several of these species were recorded by the method of laser induced fluorescence excitation spectroscopy. For HgCl the resultant spectra recorded over the 368-267nm range reveal an extensive vibrationally and isotopically resolved structure due to transitions between {dollar}\rm X\sp2\Sigma\sp{lcub}+{rcub}\ (2\ge v\sp{lcub}\prime\prime{rcub}\ge0){dollar} and {dollar}\rm B\sp2\Sigma\sp{lcub}+{rcub}\ (75\ge …
Astroglial Insulin-Like Growth Factor Binding Proteins: Regulation Of Synthesis And Relationship To Cell Growth, Sheri Lynn Bradshaw
Astroglial Insulin-Like Growth Factor Binding Proteins: Regulation Of Synthesis And Relationship To Cell Growth, Sheri Lynn Bradshaw
Digitized Theses
The insulin-like growth factors (IGFs) regulate the growth and differentiation of a wide variety of tissues, including the brain. The biologic actions of IGFs are modulated by a family of six IGF binding proteins (IGFBPs), which, like IGFs, are synthesized as paracrine factors. We hypothesized that the IGFBPs synthesized by astroglial cells, are regulated by growth factors produced in the developing brain, and modulate the growth of these cells. Primary astroglial cells synthesized IGFBP-2 and IGFBP-3 which were upregulated in a dose dependent manner by IGF-I, IGF-II, and very high concentrations of insulin, suggesting that the growth factors regulate their …
Wake Aerodynamics For 2d Bluff Bodies, Horia Mihai Hangan
Wake Aerodynamics For 2d Bluff Bodies, Horia Mihai Hangan
Digitized Theses
Wake aerodynamics of bluff bodies is a vast and challenging domain and new theoretical, experimental or numerical approaches to this subject are expected to produce a great impact on a large palette of academic and practical topics.;A new description of the wake turbulent field is introduced in the present doctoral research. This wake model is further on applied to loading problems on isolated and buffeted structures.;Following a comprehensive review, a wake turbulence model is defined. Making use of a simple "variable filtering" eduction method, focusing on coherent turbulence rather than on random turbulence, and employing flow dimensions rather than body …
Properties And Regulation Of The Calcium Ion Pump In Heart And Skeletal Muscle Sarcoplasmic Reticulum, Cynthia Elaine Hawkins
Properties And Regulation Of The Calcium Ion Pump In Heart And Skeletal Muscle Sarcoplasmic Reticulum, Cynthia Elaine Hawkins
Digitized Theses
In heart and skeletal muscle, the sarcoplasmic reticulum (SR) plays a critical role in the contraction-relaxation cycle of the myocyte: a Ca{dollar}\sp{lcub}2+{rcub}{dollar} channel releases Ca{dollar}\sp{lcub}2+{rcub}{dollar} from SR into cytoplasm to trigger contraction, and a Ca{dollar}\sp{lcub}2+{rcub}{dollar} pump resequesters Ca{dollar}\sp{lcub}2+{rcub}{dollar} to cause relaxation. A major regulator of this cycle is {dollar}\rm Ca\sp{lcub}2+{rcub}{dollar}/calmodulin-dependent protein kinase (CaM kinase), which is known to phosphorylate and thereby activate the cardiac SR Ca{dollar}\sp{lcub}2+{rcub}{dollar} pump, Ca{dollar}\sp{lcub}2+{rcub}{dollar} channel and endogenous Ca{dollar}\sp{lcub}2+{rcub}{dollar}-pump inhibitor phospholamban. This thesis examines the Ca{dollar}\sp{lcub}2+{rcub}{dollar} pump and its regulation in different tissues (cardiac, slow-twitch and fast-twitch muscle SR: CMSR, SMSR and FMSR) and different stages in …
The Behaviour Of Reinforced And Unreinforced Embankments On Rate-Sensitive Clayey Foundations, Sean Douglas Hinchberger
The Behaviour Of Reinforced And Unreinforced Embankments On Rate-Sensitive Clayey Foundations, Sean Douglas Hinchberger
Digitized Theses
Simplified design methods for reinforced embankments constructed on soft clayey foundations are advanced. A conventional elastoplastic finite element model is used to develop an approximate procedure for estimating the reinforcement strain at failure for geosynthetic reinforced embankments constructed on nonhomogeneous clayey foundation soils.;In 1989, geotextile reinforced test embankment was constructed to failure on a soft clayey silt deposit with some organics at Sackville, New Brunswick, Canada. A laboratory investigation into the rate sensitive behaviour of the Sackville foundation soil at yield is described and the ability of the two elasto-viscoplastic yield surface models, coupled with Biot consolidation theory, to describe …
Some Physiological Effects Of Stress In The American Cockroach Periplaneta Americana (L), Shigui Liu
Some Physiological Effects Of Stress In The American Cockroach Periplaneta Americana (L), Shigui Liu
Digitized Theses
The effects of different forms of stress on the American cockroach, Periplaneta americana (L.) have been systematically examined. This study demonstrated that at least two stress-related events occurred in the haemolymph of the American cockroach. First, the data clearly indicated that a large increase in hypertrehalosemic hormones occurred in the haemolymph of stressed cockroaches. Secondly, proteolytic activity in the haemolymph of stressed cockroaches was greatly increased. The increase of both hypertrehalosemic hormones and proteolytic activity in the haemolymph appeared to be a non-specific response to different forms of stress, including chemical poisoning with lindane, immobilization, forced movement, starvation, and elevated …
Differential Effects Of Ovarian Hormones On The Left And Right Cerebral Hemispheres: Evidence From Perceptual And Motor Asymmetries, Larissa Araxe Mead
Differential Effects Of Ovarian Hormones On The Left And Right Cerebral Hemispheres: Evidence From Perceptual And Motor Asymmetries, Larissa Araxe Mead
Digitized Theses
In the present series of experiments, the possibility that ovarian hormones act differentially on the left and right hemispheres of the adult human brain was investigated through the assessment of several behavioral asymmetries. Lateralized behaviors or performance patterns are believed to arise through underlying functional or neurochemical asymmetries in the brain. Therefore, an asymmetric effect of ovarian hormones on the underlying brain areas may be revealed as an alteration in the laterality of these behavioral patterns.;The first study involved the administration of a battery of visual and auditory perceptual asymmetry tests to a group of young women. Test sessions took …
1,4-Biradicals In Intermolecular Photocycloaddition Reactions Of Cyclic Enones With Alkenes, And, 1,4-Biradicals In Intramolecular Photocycloaddition Reactions Of Cyclic Enones With Alkenes, David Jack Maradyn
Digitized Theses
The irradiation of cyclic enones with ultraviolet light in the presence of alkenes results in the formation of cyclobutane adducts possessing head-to-head and/or head-to-tail regiochemistry. The long-accepted Corey-de Mayo mechanism predicts that the regiochemistry of the cyclobutane adducts is controlled by the relative orientation of the enone and alkene in an exciplex intermediate. Weedon and co-workers have demonstrated that partitioning of 1,4-biradical intermediates between starting material and cyclobutane products controls the product regiochemistry in the intermolecular photocycloaddition reactions of 2-cyclopentenones with alkenes.;These earlier results have been extended. The 1,4-biradical intermediates formed in the photocycloaddition reactions of 2-cyclohexenone with alkenes, in …
Testing For Mate Choice And Competition In Convict Cichlids Using Ecologically Relevant Contexts, Diane Kathleen Urban
Testing For Mate Choice And Competition In Convict Cichlids Using Ecologically Relevant Contexts, Diane Kathleen Urban
Digitized Theses
Mate choice and intrasexual competition in convict cichlids, Cichlasoma nigrofasciatum, was investigated in the laboratory, during courtship, nest building, guarding eggs, and guarding fry. During courtship, females were expected to use male body size to indicate quality and to compete for large males. Females and newly introduced males were tested under two conditions: Treatment1--the males were similar in body length; and Treatment 2--one male was larger than the other two. No significant difference was found between treatments in the frequency of female proximity to males or in the frequency of female-female aggressive behaviour. However, the large male of Treatment 2 …
Neurophysiology Of Spared Motor Tracts In Spinal Cord Injury, Dalton Louis Wolfe
Neurophysiology Of Spared Motor Tracts In Spinal Cord Injury, Dalton Louis Wolfe
Digitized Theses
Recent experimental and therapeutic initiatives have been directed towards enhancing the survival and function of preserved central axons following spinal cord injury (SCI). The continued development of these initiatives depends largely on the sensitivity of techniques to detect the presence of residual innervation in descending motor tracts. Detection of preserved innervation in SCI patients provided the focus of the present thesis.;Preserved motor innervation was investigated in patients with established SCI using transcranial magnetic stimulation of the motor cortex to elicit motor evoked potentials (MEPs) in muscles innervated below the level of the lesion. In particular, a set of experiments was …
The Low Temperature Surface Geochemistry And Kinetics Of Pyrrhotite Weathering: Influences On Acid Mine Drainage (Amd), Allen Robert Pratt
The Low Temperature Surface Geochemistry And Kinetics Of Pyrrhotite Weathering: Influences On Acid Mine Drainage (Amd), Allen Robert Pratt
Digitized Theses
Investigations were conducted into the mechanisms of pyrrhotite oxidation and dissolution. Analysis of pyrrhotite (Fe{dollar}\rm\sb7S\sb8{dollar}) near surfaces (50A) identifies 32% Fe(III) and 68% Fe(II), both bonded to sulphide. These results show pyrrhotite has the stoichiometry Fe(III){dollar}\sb2{dollar}Fe(II){dollar}\rm\sb5S\sb8{dollar}.;Air oxidized pyrrhotite surfaces are compositionally zoned. The outermost surface layer is Fe(III)-oxyhydroxide, below which exists an Fe-deficient, S-rich layer that displays a continuous, gradual decrease in S/Fe until that of the unaltered pyrrhotite. Compositional zones develop by electron and iron migration along a sequence of metal vacancies. At the surface, Fe(III)-oxyhydroxides form through reaction with adsorbed oxygen and hydroxyl species.;Pyrrhotite reacted in {dollar}\rm H\sb2SO\sb4{dollar} …
Application Of Expert Systems In Analytical And Environmental Chemistry, Qiwei Zhu
Application Of Expert Systems In Analytical And Environmental Chemistry, Qiwei Zhu
Digitized Theses
Expert systems are knowledge based computer programs that offer the possibility of combining theories with heuristic expertise, and are therefore capable of solving domain-specific problems. However, little is known about how human knowledge can be effectively and precisely transferred into computer programs. In addition, the lack of a seamless man-machine interface also causes reduced general acceptance of expert systems. In this thesis, the process of knowledge acquisition and the role of the user interface in expert systems are investigated. Results are presented that describe the development of two prototypic expert systems: SPILLexpert and GSMSdiagnosis.;The knowledge domain matrix (KDM) is an …
Algorithmic Abstraction Via Polymorphism In Object-Oriented Programming Languages, Qingyu Zhuang
Algorithmic Abstraction Via Polymorphism In Object-Oriented Programming Languages, Qingyu Zhuang
Digitized Theses
The abstraction gap between algorithms and functions (procedures) causes numerous duplicate efforts in implementing the same algorithms as well as apparent under-use of many efficient algorithms. A solution to this problem is to realize algorithmic abstraction at the programming language level in addition to data abstraction. For this purpose, a programming language needs to have (1) an adequate type hierarchy for defining the domains of algorithms and (2) proper constructs for writing the sequences of steps of algorithms that are polymorphic to all types of objects in an algorithm domain.;Many object-oriented programming languages use a two-level hierarchy of entities (objects …
Job Matching And Unemployment Dynamics, John Robert Kennes
Job Matching And Unemployment Dynamics, John Robert Kennes
Digitized Theses
The first chapter of the thesis considers a job search model with entrepreneurial decisions by unemployed workers. A conventional job search model predicts a log-linear relationship between the vacancy: unemployment ratio and the job finding rates of unemployed workers. However, empirical evidence suggests that the relationship is concave. The model presented in this chapter exhibits concavity as a result of entrepreneurial specialization in the pool of unemployed workers.;The second chapter of the thesis develops a general equilibrium model of vacancies and unemployment with competition between on and off-the-job searchers. Under-employed workers at low productivity jobs make up the pool of …
Communication, Culture And Reproduction: Analysis Of Contraceptive Adoption In Kenya, Lewis Odhiambo Omwanda
Communication, Culture And Reproduction: Analysis Of Contraceptive Adoption In Kenya, Lewis Odhiambo Omwanda
Digitized Theses
This dissertation explored the relationships between social communication, culture and reproductive behaviour. Drawing upon theories of structural and behavioral change, mechanisms of value formation and transformation over time were discussed and used to build upon Lesthaeghe and Surkyn's (1988) postulation linking the ideational system reproductive behaviour. Accordingly, theories that posit reproductive choices in sub-Saharan Africa as primarily rooted in past practices and traditional value systems were questioned and, instead, interactionist bases of reproductive choice were suggested that accord with communication theories of behavioral innovation and social change.;The theories were tested using the 1989 Kenya Demographic and Health Survey data, and …
Impact On Asia Of China's Trade, Foreign Investment, And Factor Market Reforms: A General Equilibrium Approach, Winnie Lam
Digitized Theses
This thesis assesses the effects of China's trade, foreign investment, and factor market reforms on China and on its neighbouring Asian countries using a static, multi-country computational general equilibrium model. Existing literature concentrates on the analysis of the piecemeal abolition of distortions in the Chinese economy (Zhuang (1992)). One notable feature of this study is that special emphasis is placed on the interactive effects among individual reforms in China. This issue is particularly important for Chinese policy makers as they embark on the experimentation with major economic reforms. The results indicate that trade reform would not be nearly as successful …
An Imperfect Competition Suite, Brian Allen Rivard
An Imperfect Competition Suite, Brian Allen Rivard
Digitized Theses
This thesis consists of three essays on unrelated topics. The first essay examines the macroeconomic issue of sunspot equilibria, while the second and third essays examine issues in the field of industrial organization relating to exclusive contracts and advertising. Each essay is unified in that the role of imperfect competition is a central focus in the analysis of its respective topic.;Chapter 1 of the thesis constructs a simple overlapping generations model with money and production in an environment of monopolistically competitive firms and an increasing returns to scale production technology. Within this framework, symmetric stationary sunspot equilibria are generated without …
Professor John Simson And The Growth Of Enlightenment In The Church Of Scotland, Anne Skoczylas
Professor John Simson And The Growth Of Enlightenment In The Church Of Scotland, Anne Skoczylas
Digitized Theses
Historians have seen John Simson (1668-1740) as either a heretic or a rationalist. He is a frequently mentioned, but seldom analysed, figure in eighteenth century Scottish history. This dissertation seeks to place Simson in his doctrinal and political context, proving that he was a faithful Calvinist Whig whose career was an important factor in creating conditions in which the Scottish Enlightenment could flourish with the approval and protection of the Church of Scotland.;Simson was elected to the Glasgow University Divinity chair in 1708. Despite his conventional background and education as a son of the manse, within a few years he …
The Effects Of Government Policies On (Un)Employment In A Search Model, Mingwei Yuan
The Effects Of Government Policies On (Un)Employment In A Search Model, Mingwei Yuan
Digitized Theses
This thesis studies the effects of fiscal and labour market policies on the labour market activities. The study is based on a general equilibrium framework. The models considered in this thesis are built on the recent advances of growth models which incorporate labour market search/match activities. This study extends the previous models to address several important empirical issues.;In Chapter 1, an empirical study using multivariate vector autoregression (VAR) models shows that, in postwar U.S., employment and hours worked per worker respond differently to a temporary shock in government consumption. The shock raises hours worked per worker and reduces employment. The …
The Behaviour Of Transmission Lines Under High Winds, Souza Acir Loredo
The Behaviour Of Transmission Lines Under High Winds, Souza Acir Loredo
Digitized Theses
The behaviour of transmission lines under severe winds is examined.;Firstly, the effect of scale of turbulence on the response of a line-like structure (cable model) is investigated through wind tunnel tests, and the experimental results are successfully compared with theoretical predictions made through the statistical method using influence lines. Consistency with theory allows for the development of a new modelling approach to conductor systems using a distorted horizontal (spanwise) scale to accommodate these systems in the wind tunnel. Cables with different characteristics are simulated and tested at transverse and oblique wind incidences.;The model cables are successful in reproducing full-scale behaviour …
Berkeley's Idealism: Arguments Of The First Dialogue, Glen Woolcott
Berkeley's Idealism: Arguments Of The First Dialogue, Glen Woolcott
Digitized Theses
Berkeley's arguments in the first of Three Dialogues between Hylas and Philonous for the claim that the objects of immediate perception are existentially dependent on the mind perceiving them are examined. This claim is central to Berkeley's idealism, since once he has established it, he uses it as the basis from which to argue that apart from minds nothing exists but what these minds immediately perceive.;The first section is an examination of Berkeley's grounds for limiting objects of immediate perception to sensible qualities. The next three sections provide an account of the three arguments which Berkeley employs in his attempt …
