    Préserver l’illisible : présences de Sholem Shtern dans la vie littéraire canadienne

    No full text
    Throughout the twentieth century, Canada was a land of refuge for a large number of immigrants from the four corners of the world. Once they had settled in this country and formed cultural communities, these newcomers often generated important literary and artistic trends in their own languages, and these movements reflected both concern with the survival of their identity and adaptation to new Canadian circumstances. The artistic journey of artists who hailed from these communities has gained greater significance today, as we have come to realize that their work informs us on the openness of Canadians to diversity. However, this body of work is either captured in many different languages – and quite often, not in either official language – or it makes use of lesser known artistic media. For these reasons, this corpus often eludes the large institutions mandated to constitute and to preserve Canadian archives. This text examines the case of Yiddish writer Sholem Shtern, who emigrated from Poland in 1927 at the age of twenty, and who published many collections of poetry and essays in Canada, in the Yiddish language. Shtern campaigned vigorously in Montreal and elsewhere in North America to include Yiddish writing in the life of his community, and by so doing, to promote a certain ideal of social justice. The personal archives of the author, which were deposited at the National Library of Canada (now Library and Archives Canada) shortly after his death in 1991, raise all kinds of questions relating to the preservation of the immigrant memory and to the literary lives of cultural communities who do not express themselves in either official language. RÉSUMÉ Le Canada a été tout au long du XXe siècle, une terre d’accueil pour un grand nombre d’immigrants venant des quatre coins du globe. Une fois installés au pays et regroupés en communautés culturelles, ces nouveaux arrivants ont souvent donné naissance, dans leur langue patrimoniale, à des courants littéraires ou artistiques importants qui reflétaient à la fois des préoccupations de survie identitaire et d’adaptation aux nouvelles circonstances canadiennes. Le cheminement des créateurs issus de ces communautés prend aujourd’hui une grande valeur du fait qu’il nous renseigne sur l’ouverture des Canadiens à la diversité. Or ce corpus disponible dans plusieurs langues, la plupart du temps nonofficielles, ou via des médias artistiques peu usités, échappe la plupart du temps aux grandes institutions chargées de constituer et de préserver les archives canadiennes. Ce texte explore le cas de l’écrivain yiddish Sholem Shtern, immigré de Pologne en 1927 à l’âge de vingt ans et qui a publié au Canada plusieurs recueils de poésie et des essais en langue yiddish. Shtern a milité très fortement à Montréal et ailleurs en Amérique pour inscrire l’écriture yiddish dans la vie de sa communauté et pour promouvoir du même coup un certain idéal de justice sociale. Déposées à la Bibliothèque nationale du Canada (aujourd’hui Bibliothèque et Archives Canada) peu après sa mort en 1991, les archives personnelles de l’auteur soulèvent toutes sortes de questions relatives à la préservation de la mémoire immigrante et à la vie littéraire des communautés culturelles de langue non-officielles

    Technical Note—Two-Stage Sample Robust Optimization

    No full text
    In “Two-Stage Sample Robust Optimization,” Bertsimas, Shtern, and Sturt investigate a simple approximation scheme, based on overlapping linear decision rules, for solving data-driven two-stage distributionally robust optimization problems with the type-infinity Wasserstein ambiguity set. Their main result establishes that this approximation scheme is asymptotically optimal for two-stage stochastic linear optimization problems; that is, under mild assumptions, the optimal cost and optimal first-stage decisions obtained by approximating the robust optimization problem converge to those of the underlying stochastic problem as the number of data points grows to infinity. These guarantees notably apply to two-stage stochastic problems that do not have relatively complete recourse, which arise frequently in applications. In this context, the authors show through numerical experiments that the approximation scheme is practically tractable and produces decisions that significantly outperform those obtained from state-of-the-art data-driven alternatives. </jats:p

    Hysteresis and precession of a swirling jet normal to a wall

    No full text
    Interaction of a swirling jet with a no-slip surface has striking features of fundamental and practical interest. Different flow states and transitions among them occur at the same conditions in combustors, vortex tubes, and tornadoes. The jet axis can undergo precession and bending in combustors; this precession enhances large-scale mixing and reduces emissions of NOx. To explore the mechanisms of these phenomena, we address conically similar swirling jets normal to a wall. In addition to the Serrin model of tornadolike flows, a new model is developed where the flow is singularity free on the axis. New analytical and numerical solutions of the Navier-Stokes equations explain occurrence of multiple states and show that hysteresis is a common feature of wall-normal vortices or swirling jets no matter where sources of motion are located. Then we study the jet stability with the aid of a new approach accounting for deceleration and nonparallelism of the base flow. An appropriate transformation of variables reduces the stability problem for this strongly nonparallel flow to a set of ordinary differential equations. A particular flow whose stability is studied in detail is a half-line vortex normal to a rigid plane-a model of a tornado and of a swirling jet issuing from a nozzle in in a combustor. Helical counter-rotating disturbances appear to be first growing as Reynolds number increases. Disturbance frequency changes its sign along the neutral curve while the wave number remains positive. Short disturbance waves propagate downstream and long waves propagate upstream. This helical instability causes bending of the vortex axis and its precession-the effects observed in technological flows and in tornadoes.V. Shtern, J. M

    Sex, Scandal, Dètente, and the Politics of Emigration: The Trial of Dr. Mikhail Shtern

    No full text
    On May 29, 1974, Dr. Mikhail Shtern, an endocrinologist in the city of Vinnitsa in the Ukrainian Soviet Socialist Republic, was arrested on charges of bribery and swindling based on alleged demands for money and other forms of remuneration in return for medical treatment. His trial and subsequent conviction resulted in a sentence of eight years at an enforced regime labor camp, and it was only after two years of incarceration that he was released based on considerations of "socialist humanitarianism." Shtern's arrest, trial and conviction are unique in that partial documentation of the events has been provided by his two sons and four other Jewish activists who witnessed the proceedings. Through the combined efforts of this small group a transcript of the proceedings of the trial itself was smuggled to the West, affording Western analysts with an almost complete record of a Soviet trial. This rare glimpse into the workings of the Soviet legal system was first published in France in 1976 under the title Un procès > en U.R.S.S.: Le Dr. Stern devant ses juges and later that same year in the United States under the title The USSR vs. Dr. Mikhail Shtern. As a student of Soviet history with a special interest in law and its applications in different nations, I was attracted to this unusual documentation and felt that, using it as my main source, I could explore the intricacies of the Soviet legal system in action. With this idea in mind I first picked up the record of Shtern's "ordinary" trial, intending to use it as the basis for a case study of Soviet justice. I was quick to learn, however, that Dr. Shtern's trial was anything but ordinary

    An adaptive robust optimization model for parallel machine scheduling

    No full text
    Real-life parallel machine scheduling problems can be characterized by: (i) limited information about the exact task duration at the scheduling time, and (ii) an opportunity to reschedule the remaining tasks each time a task processing is completed and a machine becomes idle. Robust optimization is the natural methodology to cope with the first characteristic of duration uncertainty, yet the existing literature on robust scheduling does not explicitly consider the second characteristic the possibility to adjust decisions as more information about the tasks duration becomes available, despite that re-optimizing the schedule every time new information emerges is standard practice. In this paper, we develop an adaptive robust optimization scheduling approach that takes into account, at the beginning of the planning horizon, the possibility that scheduling decisions can be adjusted. We demonstrate that the suggested approach can lead to better here-and-now decisions and better makespan guarantees. To that end, we develop the first mixed integer linear programming model for adaptive robust scheduling, and a two-stage approximation heuristic, where we minimize the worst-case makespan. Using this model, we show via a numerical study that adaptive scheduling leads to solutions with better and more stable makespan realizations compared to static approaches.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Discrete Mathematics and Optimizatio

    Legislated Multiculturalism & Second-Generation Hybrid Identities: A Phenomenological Study of Canadian Ismaili Muslim Men in Montreal, Quebec

    No full text
    The recent controversy over the 2014 proposed Quebec Charter of Values suggests the integration of minorities is, at present, a fundamental social and political debate in such a multicultural nation as Canada. Yet, minimal consideration has been given to second-generation citizens who find themselves living between various dimensions of culture. This study examines the impact of legislated multiculturalism and how it has evolved to influence second-generation Canadians in this country. This qualitative research explores the contemporary challenges of multiculturalism by examining the phenomenological analysis of second-generation Canadian Ismaili Muslim men in Montreal, Quebec. In-depth interviews were conducted to expand their perspective of identity negotiation in Canada. Research findings suggest that a symbolic sense of identity is created by simultaneously being part of the cultures found in Quebec, Canada and the global Ismaili Muslim diaspora community. This study argues that research participants challenge fixed conceptions of cultural identity markers; that their sense of diaspora community is indispensable to their perception of home and belonging in Canada; and that the legislation of multiculturalism is a practical and positive influence for second-generation Canadians. This discussion of the second-generation identity, along with the literature review and findings, provides further insight into the Canadian approach of multiculturalism

    Is the Canadian Media Ready for a Tahrir Moment?: Comparing the Canadian Media’s Framing Strategy of Social Movements at Home and Abroad

    No full text
    Mainstream media use “the protest paradigm” in framing social movements. The protest paradigm frames protests negatively by marginalizing protesters, trivializing their demands, focusing more on violent and dramatic issues instead of trying to establish a rational discussion around the reasons behind the protests and by neglecting the existence of their presence by simply not covering the protests at all. . The main function of a social movement is to challenge the status quo, while a main function of the mainstream media is arguably to contribute to the governance of society and the maintenance of public order; in a sense, to maintain the status quo. Thus, a main reason behind the consistent usage of the protest paradigm in covering protests is the conflict between social movements and mainstream media in society. But is it easier for mainstream Canadian media to challenge the status quo abroad than at home? Are Canadian media more reliant on the protest paradigm for covering global protest than local ones? Grounded in the theory of Media Framing, particularly the works of Entman (1993) this thesis compares the framing strategy that various Canadian media outlets applied while covering the 2011 Egyptian Uprising and the Occupy Toronto Movement. Empirical data collected by conducting deductive content analysis is applied to the coverage of the Toronto Edition of the Toronto Star, The Global and Mail and The Toronto Sun during the 18 days of the Egyptian uprising in January and February 2011 and the 42 days of Occupy Toronto from October 14th till November 24th, 2011 . The main argument of this thesis is that the Canadian media did not follow consist framing strategy in covering the two protests’ activities. The literature of the protest and media only focus on the notion of challenging the status quo without taking into consideration the factor of the location of the protests. Consequently, this paper is trying to add the location factor to the literature by trying to discover if the Canadian media is taking the same position from social movements that challenge the status quo regardless of where it is taking place or not
