Finding the Open Spaces in Closed Systems: An Exploration of Critical Pedagogy with a Social Justice Directive in an Ontario Secondary School Classroom

This study examines the first experience of students, teachers, and an administrator in implementing a teacher-designed Leadership in Social Justice Program at a large urban Ontario secondary school. The program aimed to infuse a Freirean concept of critical pedagogical praxis (Freire, 1970/1993) in a grade 12 integrated educational experience with a social justice directive. Data were collected through two questionnaires and eight in-depth interviews. The data identified three areas of awareness that described ways in which student participants were impacted most profoundly (a) developing self-awareness, (b) understanding a new educational paradigm, and (c) finding a place in the world. The study found that the program was successful in highlighting the possibility for more meaningful education and engaged many students deeply; however, its success was limited by the lead teacher’s failure to fully grasp and implement tenets of Freirean critical pedagogy that involved the role of the teacher in pedagogical processes.

Micromorphology of Last Glacial Maximum Grounding line sediments around the Antarctic Peninsula

Sediments recovered from seven Last Glacial Maximum grounding lines sites, around the Antarctic Peninsula, were analyzed using micromorphology. This is the first evidence that grounding line sediments from around the Antarctic Peninsula have complex deformational histories and subglacial origins. It was determined that grounding zone wedge contain multiple units, or diamicton layers, with homogenized boundaries. The multiple diamicton units / layers are due to the accretionary formation of a grounding line wedge. All the sediments were deposited via deformation, and continual reincorporation, homogenization of lower diamicton layers by upper diamicton layers produced what macroscopically appeared to be a single massive diamicton unit. The morainal ridge that was sampled, alternatively, is composed of a single unit, or diamicton layer, that was subglacial in origin and believed to have been pushed out to form a ridge that was subsequently deformed via glacial push.

Wakeman Burritt fonds, 1807-1814

Wakeman Burritt (1785-1847) was a merchant and ship owner who conducted his business in New York, New Orleans, LA, Charleston, SC, and the West Indies. Despite the difficulties that the Embargo Act of 1807 and the War of 1812 posed to trade and commerce, Burritt managed to run a successful business, dealing in commodities such as foodstuffs, cloth, cotton, and soap. He owned three ships, the Brig Cannon, Brig Eunice and Brig Sampson. In 1809, he married Grace Burr (1787-1874). Together they had at least one child, Francis Burritt (1811-1861).

Clendenan-Thompson family fonds

Daniel Clendenan (1793-1866) was the son of Abraham Clendenan, a private in Butler’s Rangers. He was married to Susan[na] [Albrecht ] Albright, daughter of Amos Albright. Daniel and Susan[na] had twelve children and belonged to the Disciple Church. In 1826 Daniel Clendenan purchased Part lot 14, Concession 6, Louth Township from Robert Roberts Loring. On this property he built a home and conducted the business of blacksmithing and along with William Jones operated a lumber mill. Volume 1 and the first part of Volume 2 are Daniel Clendenan’s account books. Daniel and his wife Susan are buried in the Vineland Mennonite cemetery. Daniel and Susan[na]’s youngest daughter, Sarah, married widower Andrew Thompson (1825-1901), son of Charles and grandson of Solomon. Andrew Thompson had settled in the Wainfleet area in 1854 and had owned a mill in Wellandport. Daniel Clendenan, in ill health, passed ownership of Lot 14, Concession 6, Louth Township to his son-in-law Andrew Thompson. Robert Roberts Loring, the original owner of lot 14, concession 6 in Louth was born in September of 1789 in England. He joined the 49th Regiment of Foot as an ensign in December of 1804 and arrived in Quebec the following July. He served with Isaac Brock and Roger Sheaffe. In 1806 he was promoted to lieutenant. Loring was hired by Lieutenant General Gordon Drummond and accompanied him to Ireland in 1811, but the outbreak of war in the States in 1812 drew Loring back to Canada. On June 26, 1812 Loring became a captain in the 104th Regiment of Foot. On October 29 of the same year, he was appointed aide-de-camp to Sheaffe who was the administrator of Upper Canada. During the American attack on York in April 1813, Loring suffered an injury to his right arm from which he never recovered. In December of 1813, Drummond assumed command of the forces in Upper Canada and he appointed Loring as his aide-de-camp, later civil secretary and eventually his personal secretary. Loring was with Drummond in 1813 at the capture of Fort Niagara (near Youngstown), N.Y. He was also with Drummond in the attacks on Fort Niagara, settlements along the American side of the Niagara River, and then York and Kingston. In July of 1814 he was promoted to brevet major, however he was captured at the Battle of Lundy’s Lane and he spent the remainder of the conflict in Cheshire, Massachusetts. One of his fellow captives was William Hamilton Merritt. Loring remained in the army and had numerous military posts in Canada and England. He retired in 1839 and lived the last of his years in Toronto. He died on April 1, 1848.

Evaluation in Sport for Development: A Case Study of the Gansbaai Project, Football Foundation of South Africa, From A Critical Perspective

The purpose of this case study was to determine the effectiveness of sport for development (SDP) evaluation within one program in Gansbaai, South Africa through critical, independent participant inclusive program evaluation. Qualitative research was conducted on the Football Foundation of South Africa (FFSA), where semi-structured interview data were collected from administrators and participants, as were data from direct participant observations and organizational documents. Data analysis followed, according to Kvale and Brinkman’s (2008) methodology. FFSA goals were found, as were themes of social impact (i.e., regarding coach-player relationships, trust, and coaching impact on social integration). A further theme related to evaluation components and procedures. Further themes included life skill development, competition within programming, participants’ home life and social integration. Findings contribute to the SDP literature relating to program evaluation research and to FFSA administrators by providing an understanding of SDP program shortcomings, limitations, and suggested improvements.

La Parenthèse ; suivi de Tensions et enfermement dans les Cent Vingt Journées de Sodome du marquis de Sade

Ce mémoire en recherche-création explore l’enfermement volontaire et les différents types de tensions qu’il provoque. Court roman prenant la forme du journal intime, La Parenthèse met en scène un jeune homme qui décide de s’enfermer chez lui une semaine durant et s’interdit tout contact avec l’extérieur – autant pour prendre un congé temporaire de la vie qu’il mène que pour examiner les raisons de sa détresse quotidienne. Le monologue intérieur se transforme rapidement en dialogue, dès lors qu’un double vindicatif, interrompant la voix principale par des « répliques » entre parenthèses, fait son apparition. Une relation houleuse – sous tension – se tisse entre ces deux facettes du personnage tout au long des sept jours de la réclusion, les passages de dispute alternant avec des récits de souvenirs. En somme, le roman tente de dramatiser la question de l’emprisonnement de soi-même et de la limitation de l’écriture, cette limitation pouvant être à la fois malsaine et libératrice. Quant à l’essai, Tensions et enfermement dans les Cent Vingt Journées de Sodome du marquis de Sade, il part du thème de l’enfermement (en l’occurrence, celui des quatre amis qui exécutent le projet de passer quatre mois dans un château isolé) pour postuler une « architecture du désir » dans Les Cent Vingt Journées de Sodome. L’essai mobilise les ressources de la narratologie en prenant en compte les effets du texte sur le lecteur ; sont ainsi mises en évidence les tensions – sexuelle pour les protagonistes, narrative pour le lecteur – élaborées par cette écriture de l’enfermement et de la contrainte, dans laquelle le désir est toujours maintenu mais rarement satisfait.

Étude structuro-fonctionnelle de SecP43 et caractérisation de ses interactions avec SepSecS et l’ARNtSec in vitro

Selenoproteins are proteins containing selenium in the form of the 21st amino acid, selenocysteine. Selenocysteine (Sec) is directly synthesized onto its cognate tRNA (tRNA[Ser]Sec or tRNASec) and inserted into selenoproteins co-translationally with the help of various cis- and trans-acting factors. Among those factors, SecP43 has been reported to possibly play an essential role in the methylation at the 2’-hydroxylribosyl moiety in the wobble position (Um34) of Sec-tRNA[Ser]Sec and consequently reduce the expression of glutathione peroxidase 1. SecP43 also called tRNASec-associated protein has also been reported to interact in with SepSecS and tRNASec in vivo and the targeted removal of one of these proteins affected the binding of the other to the Sec-tRNASec. The initial aim of the project was to solve the structure of SecP43 by means of x-ray crystallography. Secondly, we were interested in characterizing the interaction of the latter with some of the components of the selenocysteine insertion machinery. These factors are SepSecS and tRNASec. We were able to optimize the expression and the purification of soluble form of the human homologue of SecP43 and of SepSecS by using an adapted auto-induction protocol. This was a major challenge considering that full length SecP43 has not been expressed and purify to date. We did not succeed in crystallizing SecP43. Our failure to crystallize SecP43 is probably due to the fact that it is a partially folded protein as we were able to demonstrate by SAXS (Small Angle X-ray Scattering). The SecP43 envelope calculated by SAXS displayed a rod-shape like structure. In order to enhance the stability of SecP43 required for crystallization, binding affinity studies were conducted to characterize the interaction between SecP43, tRNASec and SepSecS. We did not detect an interaction between SecP43 and tRNASec by using EMSA (Electrophoretic Mobility Shift Assay) and gel filtration. We also could not detect an interaction between SecP43 and SepSecS using a cross-linking assay. In contrast, the tRNASec/SepSecS interaction was demonstrated by EMSA and the addition of SecP43 seemed to reduce the binding affinity. Therefore, SecP43 might induce a conformational change in SepSecS in the presence of tRNASec.

Topological Invariants in Hydrodynamics and Hydromagnetics

In this thesis we are studying possible invariants in hydrodynamics and hydromagnetics. The concept of flux preservation and line preservation of vector fields, especially vorticity vector fields, have been studied from the very beginning of the study of fluid mechanics by Helmholtz and others. In ideal magnetohydrodynamic flows the magnetic fields satisfy the same conservation laws as that of vorticity field in ideal hydrodynamic flows. Apart from these there are many other fields also in ideal hydrodynamic and magnetohydrodynamic flows which preserves flux across a surface or whose vector lines are preserved. A general study using this analogy had not been made for a long time. Moreover there are other physical quantities which are also invariant under the flow, such as Ertel invariant. Using the calculus of differential forms Tur and Yanovsky classified the possible invariants in hydrodynamics. This mathematical abstraction of physical quantities to topological objects is needed for an elegant and complete analysis of invariants.Many authors used a four dimensional space-time manifold for analysing fluid flows. We have also used such a space-time manifold in obtaining invariants in the usual three dimensional flows.In chapter one we have discussed the invariants related to vorticity field using vorticity field two form w2 in E4. Corresponding to the invariance of four form w2 ^ w2 we have got the invariance of the quantity E. w. We have shown that in an isentropic flow this quantity is an invariant over an arbitrary volume.In chapter three we have extended this method to any divergence-free frozen-in field. In a four dimensional space-time manifold we have defined a closed differential two form and its potential one from corresponding to such a frozen-in field. Using this potential one form w1 , it is possible to define the forms dw1 , w1 ^ dw1 and dw1 ^ dw1 . Corresponding to the invariance of the four form we have got an additional invariant in the usual hydrodynamic flows, which can not be obtained by considering three dimensional space.In chapter four we have classified the possible integral invariants associated with the physical quantities which can be expressed using one form or two form in a three dimensional flow. After deriving some general results which hold for an arbitrary dimensional manifold we have illustrated them in the context of flows in three dimensional Euclidean space JR3. If the Lie derivative of a differential p-form w is not vanishing,then the surface integral of w over all p-surfaces need not be constant of flow. Even then there exist some special p-surfaces over which the integral is a constant of motion, if the Lie derivative of w satisfies certain conditions. Such surfaces can be utilised for investigating the qualitative properties of a flow in the absence of invariance over all p-surfaces. We have also discussed the conditions for line preservation and surface preservation of vector fields. We see that the surface preservation need not imply the line preservation. We have given some examples which illustrate the above results. The study given in this thesis is a continuation of that started by Vedan et.el. As mentioned earlier, they have used a four dimensional space-time manifold to obtain invariants of flow from variational formulation and application of Noether's theorem. This was from the point of view of hydrodynamic stability studies using Arnold's method. The use of a four dimensional manifold has great significance in the study of knots and links. In the context of hydrodynamics, helicity is a measure of knottedness of vortex lines. We are interested in the use of differential forms in E4 in the study of vortex knots and links. The knowledge of surface invariants given in chapter 4 may also be utilised for the analysis of vortex and magnetic reconnections.
