Paragenetic history of the Ordovician Trenton Group carbonates, Southwestern Ontario

Geochemical examination of the rock matrix and cements from core material extracted from four oil wells within southwestern Ontario suggest various stages of diagenetic alteration and preservation of the Trenton Group carbonates. The geochemical compositions of Middle Ordovician (LMC) brachiopods reflect the physicochemical water conditions of the ambient depositional environment. The sediments appear to have been altered in the presence of mixed waters during burial in a relatively open diagenetic microenvironment. Conodont CAl determination suggests that the maturation levels of the Trenton Group carbonates are low and proceeded at temperatures of about 30 - 50°C within the shallow burial environment. The Trenton Group carbonates are characterized by two distinct stages of dolomitization which proceeded at elevated temperatures. Preexisting fracture patterns, and block faulting controlled the initial dolomitization of the precursor carbonate matrix. Dolomitization progressed In the presence of warm fluids (60 75°C) with physicochemical conditions characteristic of a progressively depleted basinal water. The matrix is mostly Idiotopic-S and Idiotopic-E dolomite, with Xenotopic-A dolomite dominating the matrix where fractures occur. The second stage of dolomitization involved hydrothermal basinal fluid(s) with temperatures of about 60 - 70°C. These are the postulated source for the saddle dolomite and blocky calcite cements occurring in pore space and fractures. Rock porosity was partly occluded by Idiotopic-E type dolomite. Late stage saddle dolomite, calcite, anhydrite, pyrite, marcasite and minor sphalerite and celestite cements effectively fill any remaining porosity within specific horizons. Based on cathode luminescence, precipitation of the different diagenetic phases probably proceeded in open diagenetic systems from chemically homogeneous fluids. Ultraviolet fluorescence of 11 the matrix and cements demonstrated that hydrocarbons were present during the earliest formation of saddle dolomite. Oxygen isotope values of -7.6 to -8.5 %0 (PDB), and carbon isotope values of - 0.5 and -3.0 %0 (PDB) from the latest stage dog-tooth calcite cement suggest that meteoric water was introduced into the system during their formation. This is estimated to have occurred at temperatures of about 25 - 40°C. Specific facies associations within the Trenton Group carbonates exhibit good hydrocarbon generating potential based on organic carbon preservation (1-3.5%). Thermal maturation and Lopatin burial-history evaluations suggest that hydrocarbons were generated within the Trenton Group carbonates some time after 300 Ma . Progressively depleted vanadium trends measured from hydrocarbon samples within southwestern Ontario suggests its potential use as a hydrocarbon migration indicator on local (within an oilfield) and on regional scales.

The preparation and reactions of some 1, 2-dipolar species /|nI. D. Brindle. -- 260 St. Catharines, Ont. : [s. n.],

This research was directed mainly towards the investigation of the reactions of allylic amineimides. The work can be divided into two main sections. Section 1 of the thesis deals mainly with thermolysis studies of amineimides. Sections 1a and 1b represent a comprehensive survey of amineimide literature up to 1971. N-A1ly1-N,N-dirnethylarnine-benzirnide was prepared and rearranged at 1400 to l-allyl-1-benzoyl-2,2-dimethylhydrazine. A tentative mechanism involving an initial migration to the carbonyl oxygen was disproved by incorporating the amineimide system into a five-membered ring. N,N~Dimethyl-N-propargylamine-benzimidedid not rearrange on heating; but the hydrobromide, on heating, disproportionated to give 1-benzoyl~2,2,2-trimethylhydraziniumbromide and I-benzoyl-2,2~ dimethylhydrazine. l-Ally'l--l, I-dimethyl-2-benzoy-lhydrazinium bromide and 1~benzoy-1-2,2, 2-trimethy-lhydrazinium iodide both disproportionated to give l~benzoyl-2,2-dimethylhydrazine. Section 1 concludes with a discussion of the mechanisms of ally'lic migrations in amineimides proposed by J. E. Baldwin. Section 2 deals with the formation of five-membered heterocyclic compounds from amineimides by bromination. 1,1-Dimethyl-2benzoyl- 4-bromopyrazolidinium bromide was formed from N-allyl-N,Ndime thy-lamtne-benzimide , 1,1-dimethyl-2-benzoyl-4-bromopyrazol-3enium bromide from N,N~dimethyl-N-propargylamine~benzimidevia the unusual acetylenic "bromonium" ion. Hydrogenolysis of both heterocyclic compounds gave the same product. The preparation was extended by forming 2,2-dimethyl-4-bromoisoxazolinium bromide from N-allylN, N-dimethylamine-N-oxide. Sections 3 and 4 cover a number of unsuccessful attempts to synthesise other amineimides and l,2-dipolar species.

Subjective, behavioural and electrophysiological measurements of the time-course and intensity of sleep inertia after a full night of sleep /

Several recent studies have described the period of impaired alertness and performance known as sleep inertia that occurs upon awakening from a full night of sleep. They report that sleep inertia dissipates in a saturating exponential manner, the exact time course being task dependent, but generally persisting for one to two hours. A number of factors, including sleep architecture, sleep depth and circadian variables are also thought to affect the duration and intensity. The present study sought to replicate their findings for subjective alertness and reaction time and also to examine electrophysiological changes through the use of event-related potentials (ERPs). Secondly, several sleep parameters were examined for potential effects on the initial intensity of sleep inertia. Ten participants spent two consecutive nights and subsequent mornings in the sleep lab. Sleep architecture was recorded for a fiiU nocturnal episode of sleep based on participants' habitual sleep patterns. Subjective alertness and performance was measured for a 90-minute period after awakening. Alertness was measured every five minutes using the Stanford Sleepiness Scale (SSS) and a visual analogue scale (VAS) of sleepiness. An auditory tone also served as the target stimulus for an oddball task designed to examine the NlOO and P300 components ofthe ERP waveform. The five-minute oddball task was presented at 15-minute intervals over the initial 90-minutes after awakening to obtain six measures of average RT and amplitude and latency for NlOO and P300. Standard polysomnographic recording were used to obtain digital EEG and describe the night of sleep. Power spectral analyses (FFT) were used to calculate slow wave activity (SWA) as a measure of sleep depth for the whole night, 90-minutes before awakening and five minutes before awakening.

Active living in municipal parks and recreation : a case study

If quality of life is an important recreation outcome, then municipal parks and recreation management's efforts have to change because:· Over one-third of all the little kids in schools will be diabetic in their lifetime if the trends we are looking at continue. The average loss of life is about 15 years, and there is an average reduction in quality oflife by about 20 years (Jackson, 2007). This thesis is about municipal parks and recreation, an agency that controls and limits physical activity opportunity. It is also about active living; from an ecological perspective, a multi-disciplinary approach to incorporate physical activity into more 111 people's daily lives. In particular, this thesis examines one case --'. the Donutville Case - . with the intent of providing an explanation of how municipal parks and recreation can advance its management efforts to improve health outcomes of people suffering from daily physical activity deficits. More specifically, how can the tension between external and internal environments to municipal parks and recreation be better balanced to affect the change needed? Given that changing the current social reality is through making decisions, decision-making functions connected with systems theory helps identify how recreation authorities can more effectively influence environmental physical activity determinants. , Sallis et al.' (2006) ·social ecological model provides the a priori focus on active living decision-making. An integrated analogous emerging logic model is developed and presented as an efficacious strategy for how municipal parks and recreation decisionmakers can affect change. Keywords: physical activity, benefits outcomes, healthy livable community, quality of life, systems thinking, social ecological model, deci~ion-making, logic modeling, municipal parks and recreation, active living.

The neoliberalization of street vending policy in Lima, Peru: the politics of citizenship. property and public space in the production of a new urban marginality

Neoliberalism is having a significant and global impact on political, social and economic life across spaces. This work illustrates how neoliberalism is attempting to change the ways in which the urban poor - particularly those that participate in street vending - use urban spaces in Lima, Peru. Using municipal policies, newspaper articles and local academic texts I argue that there is a changing marginality in Lima that is being experienced by street vendors, and currently in los canas of Lima. In particular, I discuss formalization, a neoliberal strategy in street vending policy, which is used with eradication and social assistance strategies in attempts to re-regulate street vendors.

A Narrative Inquiry of Women in Administration: Their Voices Heard

This narrative study examined women’s experiences in leadership positions in an educational setting in Southern Ontario. Semi-structured interviews with 4 women (2 principals and 2 vice principals) revealed 4 key themes: (a) considerations prior to entering into leadership and confidence instilled by others to continue on that path; (b) ongoing challenge of maintaining work−life balance; (c) others’ perceptions of women in leadership positions; and (d) increasing number of women in leadership positions. The researcher used feminist standpoint theory to analyze data collected during interviews, which gave voice to the study’s participants and shed some light on women’s gendered experiences in leadership positions. Findings suggest that historical roots significantly influence society to continue with stereotypical gender roles, though some participants have overcome certain stereotypes. The literature review and participants’ experiences suggest that women have made some progress throughout history yet society needs to remain vigilant while striving for gender equality.

Creating and Enabling a Sustainable Livelihood for Persons with Intellectual Disabilities: A Comparative Case Study of Ghana and Canada.

Abstract Despite the plethora of published studies on rights, including employment rights, for persons with intellectual disabilities (Hatton, 2002; Tarulli, et al., 2004; Ward & Stewart, 2008), relatively few have discussed their applicability to individuals with intellectual disabilities to facilitate their full involvement in socio-economic development. This study explored the mechanisms facilitating and inhibiting the full participation of persons with intellectual disabilities in the area of employment through a comparative case analysis of policies and practices in Ontario, Canada (a developed country) and in Ghana (a developing country) both of which are signatories to the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD). The study employed targeted recruitment based on the nature of the research which is a combination of policy and practice investigation.

Best Practices of Sport For Development: A Case Study of An African Organization

Sport-for-development is the active practice of achieving social ideals through the use of sport and other traditional development programs. The purpose of this thesis was to evaluate SFD best practices from the context of an African organization development project. The case was a development organization in Zambia, Africa that was utilizing sport within its strategy. The data collection and analysis framed using Curado and Bontis (2007) MIC Matrix, the Sport For Development International Working Group’s (2007) best practices model, and B. Kidd’s (2011) Sport-in-Development Logic Model. The research supports that a SFD project is multi-faceted and should include the employment of strategic community programming on the basis of collaborative and integrative sport, health care and education. Further, the researcher found that the best practices include setting specific goals and objectives, as well as instituting regular monitoring and evaluation strategies
