This study focuses on investigating the effect of post-harvest handling conditions and storage time on the dehulling efficiency and cooking quality of two varieties of red lentils, as well as optimizing the dehulling conditions. The effects of storage time, storage moisture content and storage temperature, as well as the effect of different storage pre-treatments aiming to simulate post-harvest handling, were studied. Dehulling efficiency was mostly affected by the pre-milling moisture content, regardless of the storage conditions. Pre-treatments involving moisture content changes lowered the dehulling efficiency of both varieties of red lentils, whereas freezing and thawing cycles had less of a negative effect on the dehulling characteristics. Textural parameters were mostly affected by storage time; samples became harder after storage. The final recommendation arising from this study is to monitor the moisture content of lentils during storage as it has a detrimental effect on both the dehulling and cooking quality.

Four experiments were conducted to determine a management strategy for providing effective electrolyte concentrations in the drinking water of newly weaned piglets to encourage early fluid and feed intake [weaning age=19±1 d, n=360]. In Exp. 1, electrolytes (Vetoquinol, QC, Canada) were provided at the label dose of 60 ml/L of water for 0, 6, 12, 18 or 24 h on d1-d3. In Exp. 2, electrolytes were given ad lib at 100, 75, 50, 25 or 12.5 % of the label dose on d1-d3 (72 h). In Exp. 3, electrolytes, at the label dose, or water (control) were given ad lib on d1, d1 and d2, d1-d3, or d1 and d3. In Exp. 4, based on the results of the previous experiments, the most effective combinations of "hours/concentration/days"(12 h of 25 % or 50 % on d1 or alternate days) were tested. All piglets had water ad lib from d4-d14. In Exp. 1, higher feed disappearance was observed in the 0, 6 and 12 h/d than 18 h/d and 24 h/d electrolyte groups (P<0.05). In Exp. 2, by d14 piglets in the 12.5, 50, 75, and 100 % groups experienced lower weight gain and daily FI than those in the 25 % group (P<0.05). In Exp. 3, piglets that received electrolytes on d1 only had comparable FI to those in the water group (respectively; 64.55 g/pig/day vs. 75.59 g/pig/day; SEM=8.61). Overall, evidence indicated that weanlings tended to benefit from electrolyte administration at 25 % of the label dose and durational period of ≤ 12 h/d. However, in Exp. 4 testing neither 25 % or 50 % concentration for 12 h/d result in improved daily FI despite the increased FLI in groups given electrolytes on alternate days. The results suggest that high electrolyte intake occurred at the expense of feed intake.

The educational attainment gap between Canada’s Aboriginal and non-Aboriginal peoples both reflects and perpetuates a parallel disparity in socioeconomic conditions. Aboriginal peoples’ distrust of and disengagement from educational systems can be linked to the history of their relationship with the settler state. Therefore, decolonizing education may be one way to address the education gap. This qualitative study of ten Aboriginal graduates from one of Urban Circle’s post-secondary programs explored graduates’ perceptions of the integration of Aboriginal cultural context and content in their program and the effect of these experiences on program completion. Responses revealed five main themes: 1) the cultural context of Urban Circle restored Aboriginal identity; 2) supportive relationships were important to graduates’ success in the FSW/FASD program; 3) the Life Skills course facilitated personal growth, employment readiness and program success; 4) the cultural context of Urban Circle has influenced graduates’ professional work; and 5) Urban Circle had positive influences on graduates’ personal lives. The findings indicate that the cultural content and context at Urban Circle positively impacted student’s educational experience and contributed to their completion of their program.

Abstract Expressionism was arguably the most important art movement after the Second World War and it has in many ways influenced all subsequent art movements in the West. This thesis investigates the presence of Abstract Expressionism in Britain and responses to it in the 1950s and early 1960s. Abstract Expressionism was presented to the British public through literature and exhibitions by individual Americans and by American institutions after 1947, but it was not until 1956 that Abstract Expressionist paintings became accessible in any quantity. While it was denounced by many, it won sympathies from two main groups of artists: firstly, established painters who were exploring the incorporation of abstract form with imagery from landscape and figure, and secondly, the younger generation of art students. The British constructivists were unaffected. For these established painters, Abstract Expressionism was more of a pure inspiration than a stylistic stereotype. A few of them experienced dramatic changes of style as a result, while others showed a very restricted interest in it. The reai impact was on the young artists. Under the influence of the Independent Group, which helped in generating an awareness of a new urbanism in London, they treated Abstract Expressionism and its later development Post-Painterly Abstraction, as an authentic reflection of contemporary society. They were not only eager to contribute to it but also to embrace it as their own. At the end of the 1950s, the majority of critics had accepted current status of Abstract Expressionism. Its two major British critics, Patrick Heron and Lawrence Alloway, were activists on t he contemporary art scene. Heron restricted his argument by what was essentially a combination of the painting qualities that Roger Fry had qualified and the idealism of the 1930s abstraction promoted by Herbert Read. Alloway, on the other hand, successfully exploited Abstract Expressionism to promote a new British-movement. His ideas, inspired by Abstract Expressionism as well as American consumerism, popular culture, science and technology, were embraced by young artists. British art was thus transformed in the 1960s, to a urbanisminspired art, which came from the "real' world and was receptive to its influence, rather than retreating into landscape, a psychological inner world or the realms of artistic idealism.

Signal Transduction is mediated by protein complexes whose spatial- and temporal-distribution, composition and function within cells are often regulated by different post-translational modifications (PTM). As PTMs add or subtract a specific mass difference to a protein, mass spectrometry becomes very amenable for modification analysis. These modifications have conventionally been monitored by fragmenting the modified protein or peptide by collision induced dissociation (CID) within the mass spectrometer, and then screening for the characteristic neutral fragment or fragment ion (marker ion), which is particular to the modification in question. Unfortunately, there are two major issues with respect to the traditional mass spectrometric analysis of PTMs: (1) as there are over 300 known types of modifications, the characteristic fragmentation of only a fraction of these modifications has been studied and (2) the traditional mass spectrometric approaches can only monitor these modifications sequentially, and thus comprehensive modification analysis would be unfeasible considering the breadth of PTMs. The following work aims to address these issues by (1) analyzing PTMs that have never been characterized mass spectrometrically and (2) developing a multiplexed technique for comprehensive PTM monitoring by simultaneously screening for all known characteristic fragments. With respect to the first issue, the characteristic fragmentation of lipid modifications and HNO-induced modifications was investigated. The most prevalent indicator(s) of the modification within the mass spectra are as follows: fragmentation of N-terminal myristoylated peptides produced marker ions at 240 and 268 Th, fragmentation of cysteine farnesylated peptides produced a marker ion at 205 Th and a neutral fragment of 204 Da, and fragmentation of cysteine palmitoylated peptides produced a neutral fragment of 272 Th. For HNO-induced modifications, fragmentation of the sulfinamide- and sulfinic acid-modified peptides produced a neutral fragment of 65 Da and 66 Da, respectively. With respect to the second issue, a multiplexed technique for monitoring modifications that fragment as neutral losses, termed Multiple Neutral Loss Monitoring (MNM), has been developed, successfully validated, and then shown to be the most sensitive approach for PTM analysis. MNM, combined with a second multiplexed approach, targeted Multiple Precursor Ion Monitoring, has been used to provide a comprehensive PTM analysis.

This thesis examines the impact of Edward Said’s influential work Orientalism and its legacy in respect of contemporary reading and writing across cultures. It also questions the legitimacy of Said’s retrospective stereotyping of early examples of cross-cultural representation in literature as uncompromisingly “orientalist”. It is well known that the release of Edward Said’s Orientalism in 1978 was responsible for the rise of a range of cultural and critical theories from multiculturalism to postcolonialism. It was a study that not only polarized critics and forced scholars to re-examine orientalist archives, but persuaded creative writers to re-think their ethnographic positions when it came to the literary representations of cultures other than their own. Without detracting from the enormous impact of Said, this thesis isolates gaps and silences in Said that need correcting. Furthermore, there is an element of intransigence, an uncompromising refusal to fine-tune what is essentially a binary discourse of the West and its other in Said’s work, that encourages the continued interrogation of power relations but which, because of its very boldness, paradoxically disallows the extent to which the conflict of cultures indeed produced new, hybrid social and cultural formations. In an attempt to challenge the severity of Said’s claim that “every European, in what he could say about the Orient, was consequently a racist, an imperialist, and almost totally ethnocentric”, the thesis examines a number of different discursive contexts in which such a presumption is challenged. Thus while the second chapter discusses the ‘traditional’ profession-based orientalism of nineteenth-century E. G. Browne, the third considers the anti-imperialism of colonial administrator Leonard Woolf. The fourth chapter provides a reflection on the difficulties of diasporic “orientalism” through the works of Michael Ondaatje while chapter five demonstrates the effects of the dialogism used by Amitav Ghosh as a defence against “orientalism”. The thesis concludes with an examination of contemporary writing by Andrea Levy that appositely illustrates the legacy of Said’s influence. While the restrictive parameters of Said’s work make it difficult to mount a thorough-going critique of Said, this thesis shows that, indeed, it is within the restraints of these parameters and in the very discourse that Said employs that he traps himself. This study claims that even Said is susceptible to “orientalist” criticism in that he is as much an “orientalist” as those at whom he directs his polemic.
