This dissertation is based on my research into distinction processes (Calhoun, 1994; Cerulo 1997) between tourists and inhabitants of West Sumba in Eastern Indonesia. The imaginiaries (Castoriadis, 1987; Strauss, 2006; Lacan, 1977; Anderson, 1991; Salazar, 2012) of West Sumbanese people about foreigners also emerge from diving rumors (Bysow, 1928; Allport and Postman, 1947/1965). Their origins, dissemination, and sharpening processes, as well as their consequences will be analysed herein. This case study demonstrates how mental models of otherness are formed and reified, how they clash, and for what purposes they may be utilized. It will also analyze how imaginaries influence behavior and may lead to miscommunication in West Sumba.

The aim of this study is to analyze whiteness in textbooks for civics. The study is executed through a text analysis of two textbooks in civics for upper primary school in Sweden. In this approach a postcolonial theoretical framework is used which is thoroughly presented, after which resulted in two analytical models. One model was used to identify binary dichotomies, while the other consisted of five questions that aimed to highlight patterns regarding whiteness in the textbooks. One of the most important contributions of the postcolonial theory was the visualization of the links between historical colonialism and contemporary societal problems such as various forms of racism and discrimination. On these grounds, the theory was chosen. The result showed a partly problematic presentation in the textbooks.

Syftet med föreliggande studie är att utföra en bilderboksanalys av hur mångkulturalitet representeras i sex nutida barnböcker utgivna år 2019–2021 för att uppmärksamma och i förlängningen motverka den vithetsnorm som till stor del präglar vår kultur. Den teoretiker som främst legat till grund för studien är Robin DiAngelo som skriver om vit överhöghet och hur den ligger till grund för rasism i samhället. Resultatet har visat att de sex undersökta böckerna i relativt liten utsträckning bryter vithetsnormen. Vidare har resultatet visat att det framträder vithetsnorm i samtliga böcker då de flesta karaktärer med högutbildning och status är vita.

Nous proposons une étude de l’utilisation avancée de l’hypothèse de blancheur du bruit pour améliorer les performances de débruitage. Nous mettons en avant l’intérêt d’évaluer la blancheur du résidu par des mesures de corrélation dans différents cadres applicatifs. Dans un premier temps, nous nous plaçons dans un cadre variationnel et nous montrons qu’un terme de contrainte sur la blancheur du résidu peut remplacer l’attache aux données L2 en améliorant significativement les performances de débruitage. Nous le complétons ensuite par des termes de contrôle de la distribution du résidu au moyen des moments bruts. Dans une seconde partie, nous proposons une alternative au rapport de vraisemblance menant, à la norme L2 dans le cas Gaussien blanc, pour mesurer la dissimilarité entre patchs. La métrique introduite, fondée sur l’autocorrélation de la différence des patchs, se révèle plus performante pour le débruitage et la reconnaissance de patchs similaires. Finalement, les problématiques d’évaluation de qualité sans oracle et de choix local de modèle sont abordées. Encore une fois, la mesure de la blancheur du résidu apporte une information pertinente pour estimer localement la fidélité du débruitage. / We propose an advanced use of the whiteness hypothesis on the noise to imrove denoising performances. We show the interest of evaluating the residual whiteness by correlation measures in multiple applications. First, in a variational denoising framework, we show that a cost function locally constraining the residual whiteness can replace the L2 norm commonly used in the white Gaussian case, while significantly improving the denoising performances. This term is then completed by cost function constraining the residual raw moments which are a mean to control the residual distribution. In the second part of our work, we propose an alternative to the likelihood ratio, leading to the L2 norm in the white Gaussian case, to evaluate the dissimilarity between noisy patches. The introduced metric, based on the autocorrelation of the patches difference, achieves better performances both for denoising and similar patches recognition. Finally, we tackle the no reference quality evaluation and the local model choice problems. Once again, the residual whiteness bring a meaningful information to locally estimate the truthfulness of the denoising.

Four fatal shootings, during police interactions, of unarmed people-of-color occurred in the Portland, Oregon Metro Area from 2003 to 2010 calling into question from members of the community whether or not the officers involved and hence their representative police departments had been racially profiling. Of interest in this study is whether or not cutting edge anti-racial profiling police officer trainings have an impact on how officers in Oregon perceive members of racial minority groups. A review of literature found that previous inquiries into racial prejudice among police officers may be present and that previous efforts to address racial ethics in law enforcement have had mixed results on officer perceptions of race. Using Whiteness Theory an examination was undertaken in Oregon utilizing a mixed methodological approach to answer three questions; 1) Do police officers report their perceptions of people-of-color being impacted as a result of participating in a racial profiling training seminar?, 2) Do police officers from the state of Oregon express having held a perception of members of the racial / ethnic community as individuals prior to attending a racial profiling training?, and 3) Do police officers from the state of Oregon report having held a stereotyped perception of racial / ethnic community members before attending a racial profiling training? Findings include that some officers may be racially prejudiced and others not, but that the training, according to those participating was not impactful upon their personal perceptions of people-of-color for reasons that they saw none or little personal bias within themselves although the seminar they attended brought police - race issues back into their conscious awareness. Despite the training being well-received by all the participants they suggested the training title and description may have dissuaded other officers from attending who may have benefited from its content and format. Transferability of the data's findings is weak due to a small sample size and other limitations of the study discussed. Nevertheless, conclusions about the effectiveness of the racial-profiling-training-under-review's ability to impact these officers' perceptions and attitudes of people-of-color are made and recommendations for police and social policy as well as suggestions for future research are discussed.

This dissertation intervenes in debates in Media Studies, Gender and Sexuality Studies, Canadian Immigration Studies, and Critical Race Studies to explore how shifting news media and political representations of Muslim families reflect the complexities of what it means to be Canadian beyond holding citizenship. In the post-9/11 era, the Muslim family has re-emerged in Canadian English-language news media and Canadian political debates as a site of inherent violence. Drawing on orientalist narratives of the Muslim family, news media and political conversations tend to frame these homes as being headed by patriarchal fathers and oppressed mothers, and children seeking to break from families and traditions, yet always holding the potential to become violent themselves. Even though Canada identifies as a multicultural nation, Muslim families are often presented in media as undeserving of the rights of Canadian citizenship, and even deserving of state violence. While news media play a key role in reproducing orientalist framings of Muslim families, news media can also take the government to task when it comes to the violation of immigrant and racialized Canadians’ rights as citizens. Some news media coverage counter orientalist narratives by producing “positive” representations of Muslim families, however, these “positive” representations frequently frame Muslims who are worthy of the rights of citizenship as adhering to heteronormative family dynamics, productive citizenship, and normative Western gender roles and kinship formations. These “positive” portrayals produce varying representations of Muslim families, but such framings can also labour in the way of reifying Canada’s multicultural ideals and Canada’s idea of itself as “civilized.” Drawing on the news media coverage of the family of Maher Arar, the Khadrs, and the Shafias, I argue that such representations still produce the norms of the settler-colonial Canadian nation, where some racialized bodies, in this case Muslim families, can be granted the rights of Canadian citizenship if they are able to proximate normative Canadian kinship formations. / Dissertation / Doctor of Philosophy (PhD) / In the wake of 9/11, many Canadian English-language news media have framed Muslim men as violent and Muslim women as oppressed. This dissertation analyzes the shifting Canadian news media portrayals of the Muslim family. Muslim homes in Canada are often portrayed as spaces for the perpetuation of violence that threatens the Canadian nation. Simultaneously, news media also portray some Muslim homes as spaces of purportedly “good” Canadian citizens, if these Muslim families are able to conform to Canadian “values.” I examine how Canadian news media mobilize heteronormativity, middle-class status, productive citizenship, among others, to portray some Muslims as ascribing to Canadian values, and therefore worthy of the rights of citizenship. Drawing on the news media coverage of the cases of Maher Arar and Monia Mazigh, Ahmed and Omar Khadr and Maha Elsamnah, and Mohammed Shafia, Rona Mohammed, and Tooba Yahya, I analyze how Muslims who are viewed as not assimilating to Western ideals of family are deemed as undeserving of the rights of citizenship, and, in addition, may even deserve violence.

<p> </p> <p>Issues of social justice continue to permeate all aspects of life in the United States. Acknowledging recent calls for racial justice, as well as efforts to restrict what is taught in mathematics classrooms, researchers and practitioners are increasingly exploring the promises of teaching mathematics for social justice in secondary mathematics classrooms. This dissertation contributes to research about how a social justice mathematics course can be utilized in teacher education programs to support prospective mathematics teachers’ (PMTs’) development of their mathematics identities, as well as how PMTs translate social justice mathematics theory into</p> <p>practice with their secondary mathematics students. This research complexifies the role of primarily white mathematics teachers and teacher educators working toward teaching</p> <p>mathematics for social justice by foregrounding some of the ways in which social justice mathematics curricula and instruction may continue to center whiteness. </p> <p><br></p> <p>This dissertation includes three studies focused on the design and delivery of a social justice mathematics course offered to undergraduate students, as well as the learning outcomes</p> <p>for 11 PMTs enrolled in the first iteration. As such, each study is formatted for submission to a research journal and contains its own questions, methods, findings, discussion, and conclusion. </p> <p><br></p> <p>The first and second studies detail the experiences of PMTs in a social justice mathematics course. In the first study, I explored how engaging in such a course contributed to PMTs’ mathematics identities. Findings in this case study suggest that sustained engagement with social justice mathematics can contribute to PMTs’ conceptions of mathematics and encourage them to address issues of social justice in their mathematics classrooms. Building on this, three of the PMTs enrolled in the course and I engaged in a critical participatory action research study to investigate their experiences working toward teaching mathematics for social justice in their secondary mathematics field placements. Prior to engaging their students with social justice mathematics tasks, the PMTs focused on developing relationships and trust with students and also maintained a commitment to engaging students with dominant mathematics. </p> <p><br></p> <p>Informed by a finding in the first study (i.e., PMTs continued to view mathematics as objective and neutral), in the third study, I investigated the prominence of whiteness in the development and facilitation of the course. Using action research and critical whiteness studies, I detail areas in which I perpetuated whiteness, as well as areas in which I began to make progress.</p>
