Stochastic particle models: mean reversion and burgers dynamics. An application to commodity markets

The aim of this study is to propose a stochastic model for commodity markets linked with the Burgers equation from fluid dynamics. We construct a stochastic particles method for commodity markets, in which particles represent market participants. A discontinuity in the model is included through an interacting kernel equal to the Heaviside function and its link with the Burgers equation is given. The Burgers equation and the connection of this model with stochastic differential equations are also studied. Further, based on the law of large numbers, we prove the convergence, for large N, of a system of stochastic differential equations describing the evolution of the prices of N traders to a deterministic partial differential equation of Burgers type. Numerical experiments highlight the success of the new proposal in modeling some commodity markets, and this is confirmed by the ability of the model to reproduce price spikes when their effects occur in a sufficiently long period of time.

An investigation into the physical and psychological stress factors that elementary teachers experience : recommendations to boards and personal calming strategies /

The prlmaiy objective of this study was to Identify and describe the physical and psychological stress factors that elementary school teachers experience and how teachers cope with stress. A secondary objective was to offer boards and teachers potential coping strategies counteracting stress and the effects of stress. The sample consisted of 120 elementaiy teachers from southern Ontario. Ten elementaiy schools were randomly chosen. The Teacher Stress Inventory questionnaire (Flmian, 1989) was used. Data were analyzed using a variety of statistics. Test norms and interpretations were performed based on standard results obtained from the author of the questionnaire (Flmian, 1988). Overall, the results indicated that work-related stressors were the main factor for teacher stress. This Included such factors as caseload/class is too big, too much administrative paperwork, and having little time to prepare lessons. Implications for further research and practical suggestions for further reseairch are discussed. Also a variety of recommendations to boards and for individual use are discussed. Some recommendations are having counselling available for teachers, workshops on how to handle stress, and learning how to breathe and using calm visualization.

An in-depth analysis of real and perceived barriers to speech and language program participation for children with speech and language delays : a question of barriers to service?

The current study investigated the effects that barriers (both real and perceived) had on participation and completion of speech and language programs for preschool children with communication delays. I compared 36 families of preschool children with an identified communication delay that have completed services (completers) to 13 families that have not completed services (non-completers) prescribed by Speech and Language professionals. Data findings reported were drawn from an interview with the mother, a speech and language assessment of the child, and an extensive package of measures completed by the mother. Children ranged in age from 32 to 71 mos. These data were collected as part of a project funded by the Canadian Language and Literacy Research Networks of Centres of Excellence. Findings suggest that completers and non-completers shared commonalities in a number of parenting characteristics but differed significantly in two areas. Mothers in the noncompleting group were more permissive and had lower maternal education than mothers in the completing families. From a systemic standpoint, families also differed in the number of perceived barriers to treatment experienced during their time with Speech Services Niagara. Mothers in the non-completing group experienced more perceived barriers to treatment than completing mothers. Specifically, these mothers perceived more stressors and obstacles that competed with treatment, perceived more treatment demands and they perceived the relevance of treatment as less important than the completing group. Despite this, the findings suggest that non-completing families were 100% satisfied with services. Contrary to predictions, there were no significant differences in child characterisfics and economic characteristics between completers and non-completers. The findings in this study are considered exploratory and tentative due to the small sample size.

A Foucauldian Analysis of Power and Representation in an Attempt to Run a Photovoice Project with Youth

This project evolved out of a search for ways to conduct research on “others” in a way that does not exploit, stigmatize or misrepresent their experience. This thesis is an ethnographic study in leisure research and youth work and an experiment in running a photovoice project. Photovoice is a participatory visual method that embodies the emancipatory ideal of empowering others through self-representation. The literature on photovoice lacks a comprehensive discussion on the complexity of power and representation. Postmodern theorists have proposed that participatory methods are not benign and that initiatives are acts of power in themselves that produce effects (Cook & Kothari, 2001). A Foucauldian analysis of power is used to deconstruct the researcher’s practice and reflect on why and how youth are “engaged”. This project seeks to embrace the principle of working “with” others, but also work from a postmodern perspective that acknowledges power and representation as ongoing problems.

Crowland Municipality : an act for regulating and governing auctioneers, and other persons putting up for sale, goods, wares, and merchandise to the highest or best bidder., 1854

On February 1st, 1854 an act was passed in order to regulate the sale of goods, wares and merchandise. Section I pertained to the fact that any merchant would first obtain a license. Section II deemed that no merchant should sell any wine or spirituous liquors, beer or ale within the municipality of Crowland in any less quantity than 5 gallons or less than 12 bottles in any place other than a House of Public Entertainment without having obtained a license. Section III was in regard to licensing any person who would use a billiard table which was set up for hire or gain. Section IV stated that all sums of money paid by the keepers of Houses of Public Entertainment plus the imperial duty of 2 pound would be payable to the Treasurer of the Municipality of Crowland. Section V was written regarding the continuance of the act to regulate inns, taverns, temperance houses and other Houses of Public Entertainment. Section VI specified that all recesses (not authorized to sell liquor) would pay the sum of 2 pounds. Section VII declared that Peter Benedict was appointed Revenue Inspector of the township and section VIII stated that recess-keepers who took out liquor licenses would be required to pay 6 pounds 5 shillings and for violating this they would pay a penalty. This document was written by Leonard M. Matthews, Township reeve and Alex Reid, clerk.

An Egalitarian Argument in Favour of Free Access to Healthcare and Rationing

La pensée égalitariste a traditionnellement promu l’idéal d’un système de santé universel, gratuit et accessible à tous les membres de la société. J’appuie cette position en répliquant tout d’abord à la critique qui prétend que les riches tireraient plus d’avantages que les pauvres de la gratuité du système de santé. J’ouvre ensuite la réflexion sur ce qui me semble être un enjeu crucial pour l’avenir des systèmes modernes de santé : le rationnement de l’offre. Cette idée ne plaît généralement pas à la population, aux décideurs politiques et à de nombreux égalitaristes. Je considère pourtant que les principaux arguments invoqués contre le rationnement sont incohérents ou faussement égalitaristes. La gratuité des services de santé n’est pas incompatible avec la limitation de l’offre publique.
