description: In this work, a partial heat-integrated reactive distillation process was studied to yield n-propyl acetate. To optimize the operating parameters of two distinct processes, the sequential iteration optimization method was employed. The heat exchanger network (HEN) is an effective approach for the heat-integrated design of a distillation process. Compared with the conventional reactive distillation process, the total annual cost, CO2 emissions and total energy consumption of the partial heat-integrated reactive distillation process decreased by 20.7%, 31.1%, and 32.2%, respectively. The thermodynamic efficiencies of reactive distillation process and partial heat-integrated reactive distillation process were 4.33% and 9.86%, respectively. The significance of this paper is crucial in guiding the process of partial heat-integrated reactive distillation for the production of n-propyl acetate.

description: This paper studies the interaction between production subsidies and innovation subsidies. We develop a model which allows us to calculate the socially optimal subsidies (and how they vary with changes in the economic environment), and to understand how firms react to each type of subsidy. In a three-stage game, the government chooses production and innovation subsidies in the first stage to maximize welfare in the presence of a shadow cost of public funds; two firms invest in cost-reducing R&D in the secondstage; and the two firms compete in quantities in the last stage. We find that production subsidies crowd out innovation, since they reduce the gain for firms from investing in R&D. On the other hand, providing a production subsidy reduces the cost of the innovation subsidy, and vice versa. The optimal production subsidy is U-shaped with respect to spillovers, while the innovation subsidy is increasing in spillovers. The production subsidy is higher for very low spillovers, while the innovation subsidy is higher for moderate/high spillovers. In equilibrium, because of the innovation subsidy, R&D increases with spillovers, and so does welfare. Optimal subsidies increase with research costs and with the slope of inverse demand, and have an inverted-U shape with respect to initial costs and demand height. We also consider the case of a financially constrained government, as well as the case of a uniform subsidy to production and innovation costs.
On a reduction procedure for Horn inequalities in finite von Neumann algebras

description: We consider the analogues of the Horn inequalities in finite von Neumann algebras, which concern the possible spectral distributions of sums $a+b$ of self--adjoint elements $a$ and $b$ in a finite von Neumann algebra. It is an open question whether all of these Horn inequalities must hold in all finite von Neumann algebras, and this is related to Connes' embedding problem. For each choice of integers $1\le r\le n$, there is a set $T^n_r$ of Horn triples, and the Horn inequalities are in one-to-one correspondence with $\cup_{1\le r\le n}T^n_r$. We consider a property P$_n$, analogous to one introduced by Therianos and Thompson in the case of matrices, amounting to the existence of projections having certain properties relative to arbitrary flags, which guarantees that a given Horn inequality holds in all finite von Neumann algebras. It is an open question whether all Horn triples in $T^n_r$ have property P$_n$. Certain triples in $T^n_r$ can be reduced to triples in $T^{n-1}_r$ by an operation we call {\em TT--reduction}. We show that property P$_n$ holds for the original triple if property P$_{n-1}$ holds for the reduced one. We then characterize the TT--irreducible Horn triples in $T^n_3$, for arbitrary $n$, and for those LR--minimal ones (namely, those having Littlewood--Richardson coefficient equal to 1), we perform a construction of projections with respect to flags in arbitrary von Neumann algebras in order to prove property P$_n$ for them. This shows that all LR--minimal triples in $\cup_{n\ge3}T^n_3$ have property P$_n$, and so that the corresponding Horn inequalities hold in all finite von Neumann algebras.

description: We extend de Finetti’s (1974) theory of coherence to apply also to unbounded random variables. We show that for random variables with mandated infinite prevision, such as for the St. Petersburg gamble, coherence precludes indifference between equivalent random quantities. That is, we demonstrate when the prevision of the difference between two such equivalent random variables must be positive. This result conflicts with the usual approach to theories of Subjective Expected Utility, where preference is defined over lotteries. In addition, we explore similar results for unbounded variables when their previsions, though finite, exceed their expected values, as is permitted within de Finetti’s theory. In such cases, the decision maker’s coherent preferences over random quantities is not even a function of probability and utility. One upshot of these findings is to explain further the differences between Savage’s theory (1954), which requires bounded utility for non-simple acts, and de Finetti’s theory, which does not. And it raises a question whether there is a theory that fits between these two.

description: This article elaborates on how machine learning (ML) can leverage the solution of a contemporary problem related to the security of maritime domains. The worldwide ``Illegal, Unreported, and Unregulated'' (IUU) fishing incidents have led to serious environmental and economic consequences which involve drastic changes in our ecosystems in addition to financial losses caused by the depletion of natural resources. The Fisheries and Aquatic Department (FAD) of the United Nation's Food and Agriculture Organization (FAO) issued a report which indicated that the annual losses due to IUU fishing reached $25 Billion. This imposes negative impacts on the future-biodiversity of the marine ecosystem and domestic Gross National Product (GNP). Hence, robust interception mechanisms are increasingly needed for detecting and pursuing the unrelenting illegal fishing incidents in maritime territories. This article addresses the problem of coordinating the motion of a fleet of marine vessels (pursuers) to catch an IUU vessel while still in local waters. The problem is formulated as a pursuer-evader problem that is tackled within an ML framework. One or more pursuers, such as law enforcement vessels, intercept an evader (i.e., the illegal fishing ship) using an online reinforcement learning mechanism that is based on a value iteration process. It employs real-time navigation measurements of the evader ship as well as those of the pursuing vessels and returns back model-free interception strategies.

description: The power of multiple testing procedures can be increased by using weighted p-values (Genovese, Roeder and Wasserman 2005). We derive the optimal weights and we show that the power is remarkably robust to misspecification of these weights. We consider two methods for choosing weights in practice. The first, external weighting, is based on prior information. The second, estimated weighting, uses the data to choose weights.

description: The projection pursuit index defined by a sum of squares of the third and the fourth sample cumulants is known as the moment index proposed by Jones and Sibson. Limiting distribution of the maximum of the moment index under the null hypothesis that the population is multivariate normal is shown to be the maximum of a Gaussian random field with a finite Karhunen-Loeve expansion. An approximate formula for tail probability of the maximum, which corresponds to the p-value, is given by virtue of the tube method through determining Weyl's invariants of all degrees and the critical radius of the index manifold of the Gaussian random field.

description: A new distribution (the v-Poisson) and its conjugate density are introduced and explored using computational and mathematical methods. The v-Poisson is a two-parameter extension of the Poisson distribution that generalizes some well-known discrete distributions (Poisson, Bernoulli, Geometric). It also leads to the generalization of distributions derived from these discrete distributions (viz. the Binomial and Negative Binomial). We use mathematics as far as we can and then employ computational and graphical methods to explore the distribution and its conjugate density further. Three methods are presented for estimating the v-Poisson parameters: The first is a fast simple weighted least squares method, which leads to estimates that are sufficiently accurate for practical purposes. The second method of maximum likelihood can be used to refine the initial estimates. This method requires iterations and is more computationally intensive. The third estimation method is Bayesian. Using the conjugate prior, the posterior density of the v-Poisson parameters is easily computed. We derive the necessary and sufficient condition for the conjugate family to be proper. The v-Poisson is a flexible distribution that can account for over/under dispersion commonly encountered in count data. We also explore an empirical application demonstrating this flexibility of the v-Poisson to fit count data which does not seem to follow the Poisson distribution.

description: We compare the following three notions of uniformity for a finitely additive probability measure on the set of natural numbers: that it extend limiting relative frequency, that it be shift-invariant, and that it map every residue class mod m to 1/m. We find that these three types of uniformity can be naturally ordered. In particular, we prove that the set L of extensions of limiting relative frequency is a proper subset of the set S of shift-invariant measures and that S is a proper subset of the set R of measures which map residue classes uniformly. Moreover, we show that there are subsets G of N for which the range of possible values μ(G) for μ∈L is properly contained in the set of values obtained when μ ranges over S, and that there are subsets G which distinguish S and R analogously.

description: Large, population-based samples and large-scale genotyping are being used to evaluate disease/gene associations. A substantial drawback to such samples is the fact that population substructure can induce spurious associations between genes and disease. We review two methods, called genomic control (GC) and structured association (SA), that obviate many of the concerns about population substructure by using the features of the genomes present in the sample to correct for stratification. The GC approach exploits the fact that population substructure generates `overdispersion' of statistics used to assess association. By testing multiple polymorphisms throughout the genome, only some of which are pertinent to the disease of interest, the degree of overdispersion generated by population substructure can be estimated and taken into account. The SA approach assumes that the sampled population, while heterogeneous, is composed of subpopulations that are themselves homogeneous. By using multiple polymorphisms throughout the genome, this `latent class method' estimates the probability sampled individuals derive from each of these latent subpopulations. GC has the advantages of robustness, simplicity, and wide applicability, even to experimental designs such as DNA pooling. SA is a bit more complicated, but has the advantage of greater power in some realistic settings, such as admixed populations or when association varies widely across subpopulations. It, too, is widely applicable. Both also have weaknesses, as elaborated in our review.

description: Various physical properties such as dipole moment, heat of formation and energy of the most stable formation of nucleotides and bases were calculated by PM3 (modified neglect of diatomic overlap, parametric method number 3) and AM1 (Austin model 1) methods. As distinct from previous calculations, for nucleotides the interaction with neighbours is taken into account up to gradient of convergence equaling 1. The dependences of these variables from the place in the codon and the determinative degree were obtained. The difference of these variables for codons and anticodons is shown.

description: This paper studies the sparsistency and rates of convergence for estimating sparse covariance and precision matrices based on penalized likelihood with nonconvex penalty functions. Here, sparsistency refers to the property that all parameters that are zero are actually estimated as zero with probability tending to one. Depending on the case of applications, sparsity priori may occur on the covariance matrix, its inverse or its Cholesky decomposition. We study these three sparsity exploration problems under a unified framework with a general penalty function. We show that the rates of convergence for these problems under the Frobenius norm are of order $(s_n\log p_n/n)^{1/2}$, where $s_n$ is the number of nonzero elements, $p_n$ is the size of the covariance matrix and $n$ is the sample size. This explicitly spells out the contribution of high-dimensionality is merely of a logarithmic factor. The conditions on the rate with which the tuning parameter $λ_n$ goes to 0 have been made explicit and compared under different penalties. As a result, for the $L_1$-penalty, to guarantee the sparsistency and optimal rate of convergence, the number of nonzero elements should be small: $s_n'=O(p_n)$ at most, among $O(p_n^2)$ parameters, for estimating sparse covariance or correlation matrix, sparse precision or inverse correlation matrix or sparse Cholesky factor, where $s_n'$ is the number of the nonzero elements on the off-diagonal entries. On the other hand, using the SCAD or hard-thresholding penalty functions, there is no such a restriction.

Genetic and cellular mechanisms of autoimmunity in lupus-prone B6.129-Sle16 mice
Creators: name: Buang, Norzawani Binti
Publisher: name: Imperial College London
Year: 2017

description: Genome sequencing and transcriptomic analyses are hypothesis-free approaches to identify genetic variants(s) and biological pathway(s) associated with a disease. T cells are paramount in the pathogenesis of systemic lupus erythematosus (SLE). Hyperactive CD4+ T cells can promote the production of auto-antibodies by offering excessive help to B cells. B6 congenic mice carrying the Sle16 locus (B6.129-Sle16) have increased auto-antibody levels, mild glomerulonephritis, and hyperactive T and B cells. These data indicate that intrinsic T cell abnormalities might drive the lupus-like disease development in B6.129-Sle16 mice. The aim of my thesis was to use exome sequencing and transcriptomic analysis of B6.129-Sle16 T cells from pre-disease mice to identify new candidate gene(s) and pathway(s) in lupus. Exome sequencing analysis uncovered 35 candidate genes with functional variants. RNAseq analysis of CD4+ and CD8+ T cells showed that the PYHIN gene family (Pydc4, Pydc3, Pyhin1 and Ifi204 genes) was the most differentially expressed in B6.129-Sle16 mice compared to B6 controls. PYHIN gene family expression is induced by type I interferon (IFN) and an increased IFN signature is a well-known characteristic in SLE. In my study, using in-vitro, in-vivo and ex-vivo analyses, I found no differences in the expression of IFN-inducible genes nor in pDC activation between B6.129-Sle16 mice and B6 controls. However, I observed that Pydc4 and Ifi204 gene expression could be modulated via anti-CD3 stimulation, indicating that these genes might directly regulate T cell proliferation, independent of type I IFN signalling. Altogether my findings identified new genes relevant to SLE and showed that the lupus-like disease in B6.129-Sle16 mice is independent of type I IFN, supporting the notion that lupus pathogenesis is driven by several mechanisms.

Novel therapeutic targets in uveitis
Creators: name: Tempest-Roe, Shenzhen Makahn
Publisher: name: Imperial College London
Year: 2017

description: Autoimmune posterior uveitis is a potentially blinding ocular disorder characterized by inflammation of the choroid and retina. Etiology is unknown and is assumed to be autoimmune and proposed to involve activation of autoreactive retinal-peptide specific T-cells, blood-retinal barrier breakdown, further leukocyte recruitment and ensuing ocular inflammation. The P2X7 receptor is a transmembrane purinergic receptor activated by high concentrations of ATP. Expression is ubiquitous with highest expression in immune cells. Stimulation results in the production and release of pro-inflammatory cytokines and potentiates leukocyte recruitment. Differences in mechanisms of P2X7 regulation in macrophages, dendritic cells and T cells were explored in vitro. Dendritic cells and macrophages have been proposed to release IL-1β through the NLRP3 inflammasome, requiring TLR4 stimulation followed by P2X7 stimulation. Dendritic cells were found to release IL-1β with TLR4 stimulation only, unlike macrophages which required additional P2X7 stimulus. Potential mechanisms of P2X7 regulation were explored, and it was found that T cells and not macrophages or dendritic cells exhibited significantly potentiated P2X7 mediated dye uptake upon lipid raft disruption. These results suggested a role for lipid rafts in P2X7 regulation in T cells. In vivo experiments utilized animal models of anterior, posterior and pan-uveitis. Mice deficient in P2X7 were protected against developing severe posterior uveitis, and treatment of mice with established EAU with P2X7 specific antagonist A438079 prevented the development of severe panuveitis. Finally, the role of the spleen tyrosine kinase (SYK) was investigated in murine posterior uveitis. Recent research implicates potential crossover of the P2X7 and SYK signalling pathways. SYK inhibition with the specific inhibitor fostamatinib did not prevent the development of uveitis in mice.

The first paper in the series, entitled On Psychiatry, Epidemiology, and Statistics: A View from the 1950's and 60's, was presented in 1999 at the Harvard School of Public Health. The second paper, The Growth and Future of Biostatistics (A View from the 1980's) was the 1982 invited ENAR Presidential address delivered in San Antonio. It is an honor and a privilege to be able to include them as part of this special issue of Statistics in Medicine dedicated to him. Although these talks were not part of the NIH symposium on ``Perspectives on the Biostatistical Sciences: A Symposium in Memory of Samuel W. Greenhouse'' (June 11, 2001) it seems fitting that in the first NIH biostatistics symposium in which my father did not participate, he is still able to contribute to the proceedings. In the introduction that follows, I provide some background and context for these talks.

description: We provide a closed analytical form for the gauge contribution to the beta function of a generic Yukawa coupling in the limit of large $N_F$, where $N_F$ is the number of heavy vector-like fermions charged under an abelian or non-abelian gauge group. The resummed expression is finite and for the abelian case presents a pole at the same location as for the corresponding gauge beta function. When applied to new physics scenarios characterized by large Yukawa couplings, the contribution calculated here can cure their pathological UV behavior and make the couplings asymptotically free.

Ethylene oligomerisation and polymerisation: catalyst synthesis, mechanisms and product analysis
Creators: name: Young, Craig Scott Tere
Publisher: name: Imperial College London
Year: 2017

description: Products from the oligomerisation and polymerisation of ethylene are ubiquitous in daily life. These products represent a major revenue stream for the commodity chemicals industry which, along with academia, has driven research and development into the control of polymer properties via manipulation at the molecular level. This research, conducted at Imperial College London and funded by INEOS, focuses on the synthesis, characterisation, and properties of non-Cp transition metal complexes, featuring terphenyl and aromatic ligands, and their application in the oligomerisation and polymerisation of ethylene. Conditions for the most promising candidates in catalysis have been investigated and optimised for lab conditions. The effects exhibited by these systems on polymer microstructure in terms of molecular weight, molecular weight distribution, dispersity and degree of branching have also been demonstrated. In addition, a new analytical framework is presented for describing product distributions arising from the oligomerisation and polymerisation of ethylene. This framework elucidates the mechanisms of the systems under consideration, and expounds general mathematical considerations for characterising ethylene oligomer and polymer product distributions. Chapter 1 presents the aims and objectives of this thesis and introduces several key concepts relevant to ethylene polymerisation. Chapter 2 focuses on the synthesis and characterisation of novel non-Cp Group 4 η1- complexes, featuring terphenyl ligands, and their performance as ethylene polymerisation catalysts. Chapter 3 presents the synthesis and characterisation of non-Cp Group 4 η6- and η4- complexes, featuring aromatic ligands, along with a theoretical consideration of their structure. Chapter 4 includes homogeneous and supported ethylene polymerisation results using the non-Cp Group 4 η6- and η4- complexes from Chapter 3. Chapter 5 describes a detailed analytical framework for considering product distributions from transition metal catalysed ethylene oligomerisation and polymerisation processes. Chapter 6 gives experimental procedures and supplementary information relevant to Chapters 2 – 5.

description: The finding that very large networks can be trained efficiently and reliably has led to a paradigm shift in computer vision from engineered solutions to learning formulations. As a result, the research challenge shifts from devising algorithms to creating suitable and abundant training data for supervised learning. How to efficiently create such training data? The dominant data acquisition method in visual recognition is based on web data and manual annotation. Yet, for many computer vision problems, such as stereo or optical flow estimation, this approach is not feasible because humans cannot manually enter a pixel-accurate flow field. In this paper, we promote the use of synthetically generated data for the purpose of training deep networks on such tasks.We suggest multiple ways to generate such data and evaluate the influence of dataset properties on the performance and generalization properties of the resulting networks. We also demonstrate the benefit of learning schedules that use different types of data at selected stages of the training process.

The first achievement is successfully forming a complex AA2060 (Al-Li alloy) wing stiffener demonstrator part, and an L-shape AA7075 demonstrator part, without necking or fracture, using HFQ forming technology. The feasibility of forming the aluminium alloys was based on a series of fundamental experimental tests including uniaxial tensile test, isothermal forming limit test and artificial aging test. The second achievement is the development of a novel forming limit prediction model, namely the viscoplastic-Hosford-MK model. This model enables the forming limit prediction of AA2060 and AA7075 alloys under hot stamping conditions, featuring non-isothermal and complex loading conditions. This prediction model fills a significant need in industry for accurately predicting the forming limit of aluminium alloys under such complex forming conditions. The effectiveness of the developed model was analytically verified for AA2060, demonstrating accurate material responses to cold die quenching, strain rate and loading path changes. By applying the developed model to the hot stamping of an AA2060 component, its accuracy was successfully validated. Furthermore, the viscoplastic-Hosford-MK model was also demonstrated for use in industry by determining the optimum initial blank shape of an L-shape AA7075 component. An iterative simulation procedure implementing the forming limit prediction model was used to arrive at an optimum blank shape by the minimisation of the failure criterion. The optimised initial blank shape design was applied in the experimental hot stamping of a demonstrator AA7075 component. The accuracy of the developed model was validated by the successful forming of the component, without necking or fracture.

description: Pese la existencia de anillos de seguridad, en ocasiones se presenta falta de cobertura frente a indisponibilidades no programadas de los agentes que tienen asignación de obligaciones de energía firme incluso, frene las programadas, haciendo uso de los mecanismos actuales. Lo anterior implica que los mecanismos actuales de contratación de energía a través de los anillos de seguridad del SIN, no garanticen la cobertura de las obligaciones de energía firme de los agentes y origina energía no cubierta para el cargo por confiabilidad; afectación de parámetros técnicos de las plantas que repercuten en señales distorsionadas del largo plazo (balance de energía y OEF); concentración de poder de negociación de grandes agentes, disminuyendo la posibilidad de participación de la demanda, entre otros. Se presenta el diseño de una propuesta a manera de mejora regulatoria que permita complementar y optimizar el esquema actual de los anillos de seguridad existentes. Se propone el diseño de un mecanismo complementario para la participación de los anillos de seguridad que permita gestionar de mejor manera la cobertura frente a la metodología de determinación de ODEF y proporcione una mayor cobertura de energía para los agentes generadores.
description: Although the existence of security rings, sometimes there is a lack of coverage in the face of unscheduled unavailability of agents that have firm energy obligations, even in cases of scheduled ones, using current mechanisms. It implies that the current energy contracting mechanisms through SIN security rings do not guarantee coverage of agents' firm energy obligations and causes energy not covered for the reliability charge; affectation of technical parameters of the plants that have an impact on distorted signals in the long term (energy balance and OEF); concentration of bargaining power of large agents, reducing the possibility of demand participation, among others. The design of a proposal is presented as a regulatory improvement that allows complementing and optimizing the current scheme of existing security rings. The design of a complementary mechanism for the participation of security rings is proposed, which allows better management of coverage compared to the ODEF determination methodology and provides greater energy coverage for generating agents.
La maternité des femmes victimes de violence conjugale dans le contexte de la pandémie de Covid-19
Creators: name: Brunet, Mélanie

description: Ce mémoire s’inscrit dans le cadre d’un projet de recherche qui porte sur la violence conjugale et la Covid-19. Financé par le Conseil de recherche en sciences humaines du Canada, ce projet est dirigé par le professeur Simon Lapierre et réalisé en collaboration avec l’Assemblée des groupes de femmes d’interventions régionales de l’Outaouais (AGIR Outaouais) ainsi que les maisons d’hébergement de Chaudière-Appalaches. Plus spécifiquement, ce mémoire vise à comprendre la maternité en contexte de violence conjugale pendant la pandémie de Covid-19. Pour ce faire, des entrevues individuelles ont été réalisées auprès de cinq femmes des régions de l’Outaouais et de Chaudière-Appalaches. Ces femmes étaient âgées entre 35 et 54 ans au moment de l’entrevue et avaient entre deux et trois enfants âgés entre un an et 22 ans. L’analyse des données, qui se base sur le concept de contrôle coercitif, démontre que les hommes ciblent la maternité dans leurs stratégies de violence conjugale, en utilisant les enfants pour surveiller leur conjointe ou ex-conjointe, en limitant le temps que les mères peuvent passer avec leurs enfants et en dénigrant et menaçant les mères et les enfants. De plus, les résultats révèlent que certaines mesures sanitaires, telles que le confinement et l’interdiction de rassemblement, ont exacerbé la violence. D’une part, le confinement vient augmenter l’isolement déjà vécu par les femmes et les enfants et les priver de soutien et de répit. D’autre part, l’interdiction de rassemblement vient légitimer l’utilisation de la stratégie d’isolement par les agresseurs. Toutefois, les femmes et les enfants ne restent pas passifs devant la violence. En effet, ils mettent en place des stratégies dans le but d’assurer leur sécurité et de minimiser les conséquences de la violence. Finalement, les résultats suggèrent que les publicités sur la violence conjugale ont permis à certaines femmes de prendre conscience qu’elles étaient victimes.

description: Numerical results for the local field distributions of a family of Ising spin-glass models are presented. In particular, the Edwards-Anderson model in dimensions two, three, and four is considered, as well as spin glasses with long-range power-law-modulated interactions that interpolate between a nearest-neighbour Edwards-Anderson system in one dimension and the infinite-range Sherrington-Kirkpatrick model. Remarkably, the local field distributions only depend weakly on the range of the interactions and the dimensionality, and show strong similarities except for near zero local field.

Treelets —An Adaptive Multi-Scale Basis for Sparse Unordered Data

description: In many modern applications, including analysis of gene expression and text documents, the data are noisy, high-dimensional, and unordered -- with no particular meaning to the given order of the variables. Yet, successful learning is often possible due to sparsity; the fact that the data are typically redundant with underlying structures that can be represented by only a few features. In this paper we present treelets -- a novel construction of multi-scale orthonormal bases that extends wavelets to non-smooth signals. Treelets capture the internal structure of the data and can as a dimensionality reduction tool significantly improve inference and prediction. We examine a variety of situations where treelets outperform principal component analysis and some common variable selection methods. The proposed method is illustrated on a linear mixture model, and on two real data sets: internet advertisements and DNA microarray data.
L’intervention auprès des femmes inuit vivant à Ottawa en contexte judiciaire
Creators: name: Gauthier, Gabrielle
Publisher: name: My University
Year: 2019

description: Cette recherche porte sur les intervenantes travaillant auprès des femmes inuit dans un contexte judiciaire à Ottawa. L’objectif de cette recherche est de répondre à deux questions principales : comment les travailleuses sociales peuvent-elles éviter de reproduire la violence coloniale ? Et de façon plus précise : quelles sont les limites de la profession du travail social auprès des femmes inuit et ses répercussions dans un contexte judiciaire ? Cette recherche, qui s’inscrit dans une perspective des théories féministes autochtones, a été réalisée à partir d’une analyse thématique suite à des entrevues semi-dirigées. Ces entrevues ont été effectuées en collaboration avec deux intervenantes travaillant directement auprès de femmes inuit ayant des démêlés avec la justice dans la région d’Ottawa. Cette étude démontre comment la profession du travail social a évolué et s’est installée dans un contexte colonial, et cherche à proposer des pistes pour remédier à la situation. Parmi ces pistes, on trouve l’humilité, le respect et l’ouverture d’esprit. En fait, l’analyse thématique a permis de faire ressortir 5 thèmes principaux, soit : 1) La restauration de l’harmonie et l’isolement; 2) La sensibilité culturelle; 3) La prévention par l’éducation; 4) Rester humain et le dévoilement de soi; et pour finir 5) L’écoute. Par conséquent, nous verrons également que la profession du travail social, entre autres par les lacunes de sa formation, continue de s’inscrire dans ce contexte colonial. Ce mémoire concernera l’intervention auprès des femmes inuit à Ottawa dans un contexte judiciaire, puisque la littérature à ce sujet est très minime, malgré la population grandissante de la communauté inuit dans la capitale canadienne.
