Rethinking community in Dionne Brand’s What we all long for, Ahdaf Soueif’s The map of love, Michael Ondaatje’s Anil’s ghost and Joseph Boyden’s Three day road and through black spruce
[À l'origine dans / Was originally part of : Thèses et mémoires - FAS - Département d'études anglaises]Dans cette thèse, j’ai étudié les alternatives aux communautés normatives proposées dans les romans suivants: What We All Long For de Dionne Brand, The Map of Love d’Ahdaf Soueif, Anil’s Ghost de Michael Ondaatje aini que Three Day Road et Through Black Spruce de Joseph Boyden. En utilisant un nombre de termes clés (les aspirations, la traduction (culturelle) subversive, la guérison, l’autodétermination), j’ai examiné la critiques des communautés normatives aussi bien que la configuration des communautés alternatives développées dans les œuvres cités ci-haut.
L’étude de trois romans diasporiques et deux romans amérindiens m’a permis d’établir un « dialogue » entre deux visions du monde ainsi qu’entre deux approches aux crises des communautés normatives. En effet, la conception d’une communauté alternative présentée dans le roman de Boyden souligne le rôle important que joue la famille dans la conception d’une société postcolonial alternative. Les romans diasporiques, en revanche, évitent de fonder leurs conceptions de la communauté alternative sur la famille traditionnelle comme unité d’organisation sociale. Les communautés alternatives proposées dans les romans diasporiques sont basées sur des alliances au-delà des différences nationales, culturelles, religieuses et ethniques.
Le premier chapitre a traité la communauté affective proposée comme alternative à la communauté multiculturelle canadienne. Le deuxième chapitre a traité la communauté alternative et la mezzaterra, l’espace du quel cette communauté ressort, dans The Map of Love de Soueif. Dans le troisième chapitre, j’ai exploré la relation entre la guérison, le toucher et l'émergence d'une communauté alternative dans Anil's Ghost d’Ondaatje. Dans le dernier chapitre, j’ai analysé la façon dont l'affirmation de l'autonomie juridique et la narration pourrait contribuer à la découverte de la vision qui guide la communauté Cri dépeint, dans les romans de Boyden, dans sa tentative de construire une communauté alternative postcoloniale.
Mots clés: Communautés alternatives, traduction (culturelle) subversive, affect, communautés normatives en crise, multiculturalisme et guérisonThis dissertation studies alternatives to communities in crisis proposed in Dionne Brand’s What We All Long For, Ahdaf Soueif’s The Map of Love, Michael Ondaatje’s Anil’s Ghost and Joseph Boyden’s Three Day Road and Through Black Spruce. Using a number of keywords (longing, subversive (cultural) translation, healing, touch and self-determination), I examine each novel’s contestation of a normative, oppressive configuration of community as well as the alternative community it proposes.
Juxtaposing three diasporic novels and two Indigenous (Canadian) texts, I establish a dialogue between different worldviews and the ways they read and respond to communal crises. Unlike the alternative conceptions of community presented in the diasporic novels under consideration, the alternative conception proposed in Boyden’s novels stresses the importance of strong families to the building of an alternative postcolonial society. The diasporic texts, however, do not align their alternative communities with the traditional family as a unit of social organization and trope. These alternative communities evolve around affiliation rather than filiation. They build solidarities with the other beyond national, cultural, religious and ethnic lines of division.
The first chapter studies an alternative to Canadian multiculturalism in Brand’s What We All Long For. The second chapter examines the alternative community and the mezzaterra from which it emerges in Soueif’s The Map of Love. The third chapter explores the tightly-knit relation between healing, touch and the emergence of an alternative community in Ondaatje’s Anil’s Ghost. The last chapter studies the contribution of legal autonomy and storytelling to discovering the vision that guides the Cree community portrayed in Boyden’s novels in its attempt to build an alternative postcolonial community.
Keywords: Alternative communities, subversive (cultural) translation, affect, normative communities in crisis, multiculturalism and healin

Impacts of restoration of an uncontrolled phosphogypsum dumpsite on the seasonal distribution of abiotic variables, phytoplankton, copepods, and ciliates in a man-made solar saltern
International audienceThe restoration of an uncontrolled phosphogypsum landfill was investigated for its effects on the seasonal distribution of phytoplankton, ciliates, and copepods. Sampling was carried out monthly from September 2007 to August 2008 at four ponds of increasing salinity (A1, 41 psu; A5, 46 psu; A16, 67 psu; and C31, 77 psu) in the Sfax solar saltern (southeastern Tunisia). Physicochemical and biological analyses were carried out using standard methods. Results showed drastic reduction of phosphate input and greater diversity of phytoplankton, ciliates, and copepods than before restoration. Pennate diatoms and new ciliates, considered bio-indicators of less-stressed marine ecosystems, proliferated in the A1 pond for the first time after restoration. Copepods appeared to feed on a wide range of prey. Economically, removal of the 1.7 million m3 of phosphate improved the quality of the site's salt production, enabling the salt company to receive the quality ISO 9001 accreditation
Fatty acids and triacylglycerols composition from Tunisian Acacia species seed oil
AbstractRecently, plant seeds that have not been enough explored and exploited are cheap sources of a lot of natural molecules for industrial applications. The aim of the present study was to evaluate for the first time the composition of fatty acids and triacylglycerols (TAG) of mature unexploited seeds of some Acacia species (Acacia cyclops, Acacia ligulata and Acacia salicina) harvested in Tunisia in order to reveal their potential for human consumption.Results showed that, Acacia seed oils were mainly unsaturated (more than 71%). The polyunsaturated fatty acids were the major fractions (52–68%) with the linoleic acid as the major fatty acid (more than 52%), followed by oleic acid (15–27%) as monounsaturated fatty acid. The TAG composition was significantly different among the three Acacia species. PLL, PLO, LnLO, OLL, OOL, and OOO were the major forms. Acacia seed oil could be used as potential source of oil with high industrial value; nevertheless in vivo tests are essential to confirm its safety before use
Phenolic composition of some Tunisian medicinal plants associated with anti-proliferative effect on human breast cancer MCF-7 cells
AbstractPlants have been seen to possess the potential to be excellent biological matrices to serve as a basis for investigating the presence of promising therapeutic agents for cancer treatment. Several successful anti-cancer medicines - or their analogues - nowadays in use are plant derived and many more are under clinical trials. Under current circumstances, the purpose of this work was to test aqueous and ethanolic extracts of five aromatic and medicinal plants from arid zones on some tumor cell lines. These plants, Cymbopogon schoenanthus (L.) Spreng, Crithmum maritimum (L.) Spreng, Hammada scoparia (Pomel) Iljin, Retama raetam (Forssk.) and Zizyphus lotus (L.) Desf., widely used in Tunisian ethnomedicine, were assessed for their phenolic compounds, antioxidants and anticancer activities in aqueous and ethanol extracts. Total polyphenols, flavonoid and tannin contents were determined colorimetrically and some of these molecules were identified using RP-HPLC. A significant difference on phenolic contents and composition were found among the investigated plants. Cymbopogon schoenanthus was the richest in phenolic compounds (approx. 72%) with quercetine-3-o-rhamnoside (approx. 33%) as main contributor. For all the tested plants, the highest antioxidant capacity was detected in the ethanolic extracts rather than in the aqueous ones. The highest antiproliferative potential was observed for the ethanolic extracts. Hammada scoparia, Retama raetam and Zizyphus lotus exhibited important antiproliferative effect that reached 67% at a 1% extract concentration. Taken together, the present study supports the potential development of chemotherapeutic agents from, at least, four of the five studied Tunisian ethnomedicinal plants
The Effect of a 12-Week Moderate Intensity Interval Training Program on the Antioxidant Defense Capability and Lipid Profile in Men Smoking Cigarettes or Hookah: A Cohort Study
Aim. To examine the impact of interval training program on the antioxidant defense capability and lipid profile in men smoking cigarettes or hookah unable or unwilling to quit smoking. Methods. Thirty-five participants performed an interval training (2 : 1 work : rest ratio) 3 times a week for 12 weeks at an intensity of 70% of VO2max. All subjects were subjected to a biochemical test session before and after the training program. Results. The increase of total antioxidant status (TAS), glutathione peroxidase (GPx), and α-tocopherol, is significant only for cigarette smokers (CS) and hookah smokers (HS) groups. The decrease of malondialdehyde (MDA) and the increase of glutathione reductase (GR) are more pronounced in smokers groups compared to those of nonsmokers (NS). Superoxide dismutase (SOD) increases in NS, CS, and HS groups by 10.1%, 19.5%, and 13.3%, respectively (P<0.001). Likewise, a significant improvement of high-density lipoprotein cholesterol (HDL-C) and TC/HDL-C ratio was observed in CS and HS groups (P<0.05). Conclusion. Although the interval training program does not have a significant effect on blood lipid levels, it seems to be very beneficial in the defense and prevention programs of oxidative stress
The Effect of a 12-Week Moderate Intensity Interval Training Program on the Antioxidant Defense Capability and Lipid Profile in Men Smoking Cigarettes or Hookah: A Cohort Study
Aim. To examine the impact of interval training program on the antioxidant defense capability and lipid profile in men smoking cigarettes or hookah unable or unwilling to quit smoking. Methods. Thirty-five participants performed an interval training (2 : 1 work : rest ratio) 3 times a week for 12 weeks at an intensity of 70% of VO 2 max. All subjects were subjected to a biochemical test session before and after the training program. Results. The increase of total antioxidant status (TAS), glutathione peroxidase (GPx), and -tocopherol, is significant only for cigarette smokers (CS) and hookah smokers (HS) groups. The decrease of malondialdehyde (MDA) and the increase of glutathione reductase (GR) are more pronounced in smokers groups compared to those of nonsmokers (NS). Superoxide dismutase (SOD) increases in NS, CS, and HS groups by 10.1%, 19.5%, and 13.3%, respectively ( < 0.001). Likewise, a significant improvement of high-density lipoprotein cholesterol (HDL-C) and TC/HDL-C ratio was observed in CS and HS groups ( < 0.05). Conclusion. Although the interval training program does not have a significant effect on blood lipid levels, it seems to be very beneficial in the defense and prevention programs of oxidative stress
Effect of low- intensity continuous training on lung function and cardiorespiratory fitness in both cigarette and hookah smokers.
Background: The decline in cardiorespiratory fitness and lung function
was higher in smokers. Training method could mitigate some of the
negative consequences of smoking among smokers unable or unwilling to
quit. Objective: To examine the effects of continuous training on lungs
functional capability and cardiorespiratory fitness in smokers.
Methods: Fifteen cigarette smokers, 14 hookah smokers, and 14
nonsmokers were assigned to low-intensity continuous training (20-30
minutes of running at 40% of maximum oxygen uptake (O2max)). Lung
function and cardiorespiratory fitness parameters were determined using
respectively spirometer and treadmill maximal exercise test. Results:
Continuous training improved forced expiratory volume in one second
(FEV1) and forced expiratory flow at 50% of FVC (FEF50 %) in all
participants, smokers and nonsmokers (p < 0.05). In contrast, forced
vital capacity (FVC) improvement was significant only among cigarette
smokers (CS) (+1.7\ub12.21%, p < 0.01) and hookah smokers (HS)
(+1.3\ub11.7 %, p < 0.05). Likewise, an improvement in
cardiorespiratory fitness in both smokers groups without significant
changes in diastolic blood pressure (DBP) for CS group and in velocity
at maximum oxygen uptake (vO2max) for HS group. Conclusion: The
low-intensity continuous training improves cardiorespiratory fitness
and reduces lung function decline in both cigarette and hookah smokers.
It seems to be beneficial in the prevention programs of hypertension.
It could have important implications in prevention and treatment
programs in smokers unable or unwilling to quit
