Graffiti, memory and contested space : mnemonic initiatives following trauma and/or repression in Buenos Aires, Argentina

Graffiti, Memory and Contested Space: Mnemonic Initiatives Following Periods of Trauma and/or Repression in Buenos Aires, Argentina This thesis concerns the popular articulation ofmemory following periods or incidents of trauma in Argentina. I am interested in how groups lay claim to various public spaces in the city and how they convert these spaces into mnemonic battlegrounds. In considering these spaces of trauma and places of memory, I am primarily interested in how graffiti writing (stencils, spray-paint, signatures, etchings, wall-paintings, murals and installations) is used to make these spaces transmit particular memories that impugn official versions of the past. This thesis draws on literatures focused on popular/public memory. Scholars argue that memory is socially constructed and thus actively contested. Marginal initiatives such as graffiti writing challenge the memory projects of the state as well as state projects that are perceived by citizens to be 'inadequate,' 'inappropriate,' and/or as promoting the erasure of memory. Many of these initiatives are a reaction to the proreconciliation and pro-oblivion strategies of previous governments. I outline that the history of silences and impunity, and a longstanding emphasis on reconciliation at the expense of truth and justice has created an environment of vulnerable memory in Argentina. Popular memory entrepreneurs react by aggressively articulating their memories in time and in space. As a result of this intense memory work, the built landscape in Buenos Aires is dotted with mnemonic initiatives that aim to contradict or subvert officially sanctioned memories. I also suggest that memory workers in Argentina persistently and carefially use the sites of trauma as well as key public spaces to ensure official as well as popular audiences . The data for this project was collected in five spaces in Buenos Aires, the Plaza de Mayo, Plaza Congreso, La Republica Cromanon nightclub, Avellaneda Train Station and El Olimpo, a former detention centre from the military dictatorship.

Molecular dynamics calculation of mean square displacement in alkali metals and rare gas solids and comparison with lattice dynamics

Molec ul ar dynamics calculations of the mean sq ua re displacement have been carried out for the alkali metals Na, K and Cs and for an fcc nearest neighbour Lennard-Jones model applicable to rare gas solids. The computations for the alkalis were done for several temperatures for temperature vol ume a swell as for the the ze r 0 pressure ze ro zero pressure volume corresponding to each temperature. In the fcc case, results were obtained for a wide range of both the temperature and density. Lattice dynamics calculations of the harmonic and the lowe s t order anharmonic (cubic and quartic) contributions to the mean square displacement were performed for the same potential models as in the molecular dynamics calculations. The Brillouin zone sums arising in the harmonic and the quartic terms were computed for very large numbers of points in q-space, and were extrapolated to obtain results ful converged with respect to the number of points in the Brillouin zone.An excellent agreement between the lattice dynamics results was observed molecular dynamics and in the case of all the alkali metals, e~ept for the zero pressure case of CSt where the difference is about 15 % near the melting temperature. It was concluded that for the alkalis, the lowest order perturbation theory works well even at temperat ures close to the melting temperat ure. For the fcc nearest neighbour model it was found that the number of particles (256) used for the molecular dynamics calculations, produces a result which is somewhere between 10 and 20 % smaller than the value converged with respect to the number of particles. However, the general temperature dependence of the mean square displacement is the same in molecular dynamics and lattice dynamics for all temperatures at the highest densities examined, while at higher volumes and high temperatures the results diverge. This indicates the importance of the higher order (eg. ~* ) perturbation theory contributions in these cases.

Disrupting heterosexual space? : the implementation of a campus Positive Space Campaign

Drawing on a growing literature on the interconnection of queer theory, sexuality and space, this thesis critically assesses the development, implementation and impact of a campus-based Positive Space Campaign aimed at raising the visibility and number of respectful, supportive, educational and welcoming spaces for lesbian, gay, bi, trans, two-spirited, queer and questioning (LGBTQ) students staff and faculty. The analysis, based on participatory action research (PAR), interrogates the extent to which the Positive Space Campaign challenges heteronormativity on campus. I contend that the Campaign, in its attempt to challenge dominant notions of sex, gender and sexuality, disrupts heterosexual space. Further, as I consider the meanings of 'queer', I consider the extent to which Positive Space Campaigns may be 'queering' space, by contributing to an 'imagined' campus space free of sexual and gender-based discrimination. The case study contributes to queer theory, the literature on sexuality and space, the literature on queer organizing in educational spaces and to broader queer organizing efforts in Canada.

Understanding space, place and leisure of women over 85 living in the community

There is an increase in the number of older adults 85 and over, who are choosing to live alone within the community. Moreover, older adults who live alone are reportedly spending an extensive amount of time alone within the home environment. In an effort to provide additional support and resources to older adults living in the community, a compliment of services are being offered through public and private organizations. These in-home supports focus on the instrumental or functional tasks of daily living, such as personal and rehabilitative care, nourishment, maintenance and upkeep of the home, as well as volunteer social visitation. However leisure resources and programs are not included among these services. Consequently, this creates a gap in leisure provision among this segment of the population. Throughout the life course, an individual's identity, role and purpose are developed and sustained through instrumental work roles in the formal and informal sector, as well as through personally meaningful leisure pastimes and experiences. Although roles shift post retirement, participation in instrumental and expressive activities can provide opportunities through which older adults are able to fulfill their need for agency (individuality and autonomy) and affiliation (social relatedness). Therefore barriers that inhibit instrumental or leisure experiences can negatively impact older adults' quality of life. This study explored the leisure lifestyles of four older adults, all of whom were over 85, lived alone within the community and were oriented to person, time and place. It became apparent that participants ordered their lives around a routine that consisted of instrumental, expressive and socially integrated tasks and activities. Moreover participants purposely chose to remain at home because their home environment facilitated freedom, choice and independence. As a result all four participants viewed their independence within the home as a critical determinant to their overall quality of life. Challenges associated with the home environment, participants' personal capacities and relationships were negotiated on a daily basis. Failure to positively adapt to these challenges inhibited meaningful engagement and personal fulfillment. Traditionally, leisure service delivery has been offered within institutions and through various community based venues. As a result leisure provision has been focused on the needs of the frail elderly who reside in institutions or the well elderly who are able to access leisure amenities within the community. However the growing number of older adults electing to live alone is on the rise. As individuals age the home becomes the preferred context for leisure experiences. If older adults are choosing to live alone, then both their instrumental and leisure needs must be addressed. As a result, it is imperative that leisure professionals extend the scope of service delivery to include home centered older adults.

Patterns in space : a regional study of motif in Minoan wall painting

This thesis consists of a quantitative analysis of the regional prevalence of certain artistic motifs as they appear in Minoan wall painting of the Neopalatial period. This will help to establish the relative degree of artistic autonomy exercised by each of the sites included in this study. The results show that the argument for itinerant artists during this time period is a strong one, but the assumption that these travelling artists were being controlled by any one palace-centre is erroneous. Rather, the similarities and differences seen suggest that the choices were predicated either by the specific patrons, or by the function of the associated building or room. Thus, the motifs found within this study should be understood as constituting a cultural identity, with greater or lesser degrees of regional homogeneity, which act as one facet of a number of cultural indicators that can be used to better understand the role of artists and regional dynamics on the island during the Bronze Age.

Social neuroendocrinology of competition

The relationship between testosterone concentrations and aggressive behaviour in studies of people has produced very inconsistent findings. However, one consistent fmding that has emerged is that competitive and aggressive interactions potentiate testosterone release in both human and non-human species. It has been argued that socially-induced alterations in testosterone concentrations may function to influence ongoing and/or future social behaviour. Nonetheless, few studies have empirically tested this hypothesis. The current series of experiments was designed to address the extent to which competitioninduced fluctuations in testosterone concentrations were associated with ongoing and/or subsequent social behaviour. In Study 1, men (n = 38) provided saliva samples prior to, and at the conclusion of, the Point Subtraction Aggression Paradigm (PSAP). Although baseline testosterone concentrations were not related to aggressive behaviour, there was a positive correlation between change in testosterone and aggressive behaviour such that men who were most aggressive on the PSAP demonstrated the largest increase in testosterone concentrations. Furthermore, a rise in testosterone during the PSAP predicted willingness to choose a subsequent competitive task. In Study 2, men and women provided saliva samples prior to and after competing against a same-sex opponent on the Number Tracing Task (NTT). The outcome of the competition was rigged such that half of the individuals won most of the races, while the other half lost most of the races, thus experimentally creating a winner and loser in the laboratory. Following the competitive interaction, men and women played the PSAP with their same-sex partner. Results indicated that men selected the aggressive response (but not reward or protection responses), more frequently than women. For men assigned to the loss condition, an increase in testosterone concentrations in response to the NTT predicted subsequent aggressive behaviour. For men assigned to the win condition, an increase in testosterone concentrations in response to the NTT predicted subsequent aggressive behaviour, but only among those men who scored high on trait dominance. Change in testosterone and trait dominance did not predict aggressive behaviour in women. In Study 3, men provided saliva samples prior to, during, and at the end of the PSAP. They were randomly assigned to one of four experimental conditions that differed in the extent to which they were provoked and whether they received reward for behaving aggressively (i.e., stealing points). Results indicated that baseline testosterone concentrations did not correlate with aggression in any of the experimental conditions. Consistent with Study 1, there was a positive correlation between change in testosterone and aggressive behaviour among men who were provoked, but did not receive reward for aggression (i.e., reactive condition). Men who were provoked but did not receive reward for aggression enjoyed the task the most and were more likely to choose the competitive versus non-competitive task relative to men assigned to the other experimental conditions. Also, individual differences in aggressive behaviour among these men were positively correlated with the extent to which they enjoyed the task. Together, these studies indicate that testosterone dynamics within the context of competition influence subsequent competitive and aggressive behaviours in humans and that testosterone may be a marker of the intrinsically rewarding nature of costly aggressive behaviour.

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.

Sport for Development Organizations: An Analysis of Stakeholder Dynamics

Sport for Development (SFD) uses the power of sport to support international development initiatives that affect social change and empower under-resourced communities (Levermore, 2008a). Currently, there are more than 1,000 SFD organizations globally (Doyle, Payne, & Wolff, 2011) working to enact change and development initiatives in the least developed regions of the world. Stakeholders are key components of the long-term sustainability, development, and success of these SFD organizations. The purpose of this research is to examine the relationships between SFD organizations and their stakeholders through the lens of social responsibility (SR). Through the analysis of interviews conducted with SFD leaders and their stakeholders, this research offers a modified version of Carroll’s (1979) four categories of SR. This modified version addresses the differences that exist with SFD stakeholder relationships from the perspectives of the organizations and their stakeholders. Further, broader implications will be discussed in terms of compatibility and long-term sustainability.

Dynamics in large scale networks

In this thesis we study the properties of two large dynamic networks, the competition network of advertisers on the Google and Bing search engines and the dynamic network of friend relationships among avatars in the massively multiplayer online game (MMOG) Planetside 2. We are particularly interested in removal patterns in these networks. Our main finding is that in both of these networks the nodes which are most commonly removed are minor near isolated nodes. We also investigate the process of merging of two large networks using data captured during the merger of servers of Planetside 2. We found that the original network structures do not really merge but rather they get gradually replaced by newcomers not associated with the original structures. In the final part of the thesis we investigate the concept of motifs in the Barabási-Albert random graph. We establish some bounds on the number of motifs in this graph.

A critique of Nancy Fraser's theory of social justice : self-determination and the Mohawks of Kahnawá:ke

La présente étude se concentre sur le travail de Nancy Fraser sur la justice sociale, lequel a suscité beaucoup d’intérêt dans la littérature au cours des dernières années. La reconnaissance et la redistribution sont les deux piliers originaux de son approche: les désavantages dont souffrent les gens dus au dénigrement culturel ou à la privation économique. Ces deux concepts servent à diagnostiquer et fournir le soutien moral aux multiples luttes que les victimes d’injustice entreprennent avec l’objectif d’établir une participation plus égalitaire à la société. Cependant, que peut-elle dire cette approche des groupes qui sont marginalisés et cherchent l’autogouvernance (ou la séparation même) plutôt que l’intégration dans la société? Le travail de Fraser manifeste une résistance envers les droits du groupe, et un silence quant à l’autodétermination. Mon intervention prend comme objectif d’inclure ces formes d’injustice dans son approche, la rendant plus sensible aux dynamiques des groupes et capable de répondre à leurs revendications trop souvent négligées sous prétexte de l’égalité. La question est, l’égalité de qui?

Le design urbain au Québec : étude de la transposition des prescriptions empiriques dans la pratique urbanistique

Le design urbain, dimension de la pratique urbanistique, consiste principalement en la manipulation de la forme urbaine selon une démarche ciblée et encadrée. Les approches sont aussi nombreuses que diversifiées. On peut néanmoins les classer en deux catégories : les approches visant la forme urbaine en tant qu‟objet qui contient l‟organisation formelle de la ville et celles qui visent le travail sur la forme urbaine afin d‟organiser la dynamique urbaine humaine. Les deux types d‟approches soutiennent différentes démarches d‟aménagement qui contribuent à développer la forme urbaine et la dynamique des lieux. Parmi celles-ci se trouve la vision de type empirique, laquelle vise l‟expérience urbaine à l‟échelle du piéton. Les écrits et les théories à ce sujet sont variés et pertinents. La présente recherche porte sur la transposition des prescriptions empiriques dans la planification d‟un projet qui intègre une démarche de design urbain. Au moyen d‟une étude de cas, la Cité multimédia à Montréal, il s‟agit de comprendre plus spécifiquement comment le canevas maître du design urbain, soit l‟espace public, est étudié et reformulé et ce, en accordant une attention particulière pour la dimension empirique du futur aménagement. Quelles sont les balises ou les composantes qui permettent à la dimension empirique de se déployer dans la conception d‟un projet urbain qui vise une reformulation de la forme urbaine?

La communauté musulmane en contexte migratoire et la réarticulation d’un « cosmos sacré » islamique : le cas de l’association Bel Agir de Montréal

Cette étude d’une association musulmane de Montréal explore, à travers le concept de communauté en sciences sociales, les dynamiques religieuses et sociales animant la vie des membres de l’association Bel Agir, où une enquête de terrain de plus de six mois a été effectuée. Composée en majorité d’anciens membres d’un mouvement islamiste non violent marocain et entièrement de migrants, l’association offre un espace où sont articulées les continuités et les discontinuités dans la vie religieuse et sociale de ses membres. Ainsi, notre mémoire examine en partie le rôle de la communauté religieuse dans le processus migratoire de ses membres. Par contre, notre analyse se focalise essentiellement sur le rôle de la participation des membres à la vie de la communauté dans les processus d’intériorisation de l’éthos religieux supporté par le groupe, et de réarticulation de ce même éthos dans la société québécoise. Ce faisant, nous explorons ce qui motive les membres à s’investir dans la communauté et à intégrer les enseignements du groupe dans leur vie individuelle.

La microfinance au coeur d'une géographie du genre renouvelée au Mexique?

Le développement des sociétés à travers le monde est influencé par des dynamiques de pouvoir social. D’une perspective de genre, les relations patriarcales ont contribué à la réorganisation du développement par un accès inégal aux ressources, à l’espace et à la mobilité. La société mexicaine, caractérisée par un fort patriarcat et une pauvreté endémique, a vu émerger de multiples outils de développement pour pallier aux inégalités de genre. Plus récemment, les programmes de microfinance sont devenus un instrument de choix pour lutter contre la marginalisation des femmes et les inégalités de genre. La littérature scientifique présente des lacunes au sujet de la nature des relations de genre dans les ménages qui bénéficient de la microfinance. Plusieurs études portent sur les impacts de la microfinance sur la vie des femmes, mais peu offrent une vision holistique considérant la microfinance comme un outil de développement capable de changer la nature spatiale des inégalités de genre. Cette recherche est basée sur une comparaison qualitative de deux études de cas de groupes de microfinance de San Miguel Tenextatiloyan et d’Émilio Carranza, deux communautés de la Sierra Norte de Puebla (Mexique). Son objectif principal est d’évaluer le degré selon lequel les programmes de microfinance ont changé la place des femmes dans la société. Pour répondre à cette question, un portrait de l’organisation spatiale du genre sera tracé, puis, les impacts des programmes de microfinance sur la place des femmes dans les espaces domestiques, de travail et communautaires seront évalués. L’étude mène à la conclusion que les programmes de microfinance du CESDER n’ont pas beaucoup changé la place des femmes dans la société. La recherche dévoile plutôt que, dans un contexte de pauvreté, la microfinance stabilise les ménages et offre des lieux d’échange et de réseautage, mais elle n’offre pas aux femmes une véritable chance d’acquérir plus de contrôle sur leur vie. Deuxièmement, les résultats démontrent que les tâches associées à la reproduction sociale – largement assumée par les femmes - engendrent une barrière structurante à l’empowerment des femmes, un obstacle que la microfinance ne parvient pas entièrement à surmonter. Mots-clés : Géographie du genre, relations de pouvoir, développement, microfinance, spatialité, néolibéralisme, Mexique.

Accès social à l'eau : étude de cas dans un village mossi du Yatenga

L’objectif de ce mémoire est d’examiner l’accès à l’eau d’un point de vue non pas technologique mais social. Toute société humaine a eu à régler la question de l’accès à l’eau. C’est particulièrement le cas des populations vivant sous un climat aride comme au Sahel, où cette ressource est rare. Le village d’étude est situé au nord du Burkina Faso, dans la région du Yatenga. J’examinerai d’abord la répartition temporelle et spatiale des groupes et des puits sur le territoire, puis la question de la régulation de l’accès à l’eau en tant qu’enjeu politique au sein des structures traditionnelles. Je montrerai qu’il permet tantôt de renforcer les hiérarchies sociales existantes, et tantôt de les dépasser. J’examinerai enfin l’accès à l’eau de différents groupes d’usagers : femmes, hommes, jeunes, vieux, agriculteurs, éleveurs. Je montrerai que leur condition d’accès est implicitement régulée, et limite les possibilités d’expansion économique de certains d’entre eux. Dans cette société en mutation, les usagers désavantagés peuvent développer des tactiques leur permettant de contourner ces contraintes. L’accès à l’eau est alors pris dans un jeu de stratégies antagonistes, celle de la reproduction sociale et celle du changement.

La dinámica del ordenamiento territorial en Colombia : contraste de dinámicas urbano-rurales en la región metropolitana de Bogotá

L’aménagement du territoire est le résultat de différents processus économiques, politiques, sociaux, culturels et environnementaux. Le territoire peut être vu de différentes manières et reflète les visions et les intérêts des acteurs qui le construisent. L'objectif principal de cette thèse consiste à explorer les dynamiques qui soutiennent l'aménagement de Bogota, capitale de la Colombie, et d’une municipalité avoisinant Soacha. L'analyse se concentre sur trois aspects qui correspondent aux objectifs spécifiques de cette étude : les récentes politiques publiques d'aménagement du territoire qui régissent la zone étudiée, le rôle des acteurs sociaux et les relations urbano-rurales créées dans ce nouveau contexte. La thèse souligne des éléments contextuels qui servent à comprendre les transformations récentes de Bogota et de Soacha dans leurs implications spatiales. Différents processus ont apparus dans la nouvelle géographie de cette région, y compris la mondialisation, les transformations économiques, les nouvelles lois relatives à l'aménagement du territoire, les nouvelles formes de participation, ainsi que les décisions des administrations municipales qui ont contribué à établir ce nouvel ordre. Les éléments théoriques traitées dans cette étude privilégient deux perspectives ou visions du territoire : 1) celle utilisée par l'État où le territoire est considéré comme un espace limité par des frontières; et 2) la perspective culturaliste où le territoire est défini par son appropriation et par par l’identité qu’il confère. Cependant, une nouvelle tendance émerge à travers l'intégration de ces deux perspectives, autant en Colombie que dans d’autres pays. Ainsi, l'analyse démontre que de nouveaux acteurs ont émergé, par exemple le Conseil territorial de la planification qui représente la concrétisation du discours de participation communautaire exprimé dans différentes lois. De plus, la population paysanne qui a résisté à l'expansion urbaine de Bogota constitue un acteur primordial. Les nouveaux patrons de relations urbaine-rurale démontrent une très grande diversité d'activités et de fonctions présentes dans cette nouvelle « frontière » très dynamique où des éléments urbains et ruraux sont combinés, toujours présents mais aussi toujours en évolution.
