DENATURALIZING CULTURE: SAYED KASHUA'S NEWSPAPER COLUMNS ON THE TOPIC OF PREJUDICE
No full textAbstract Discrimination is a recurrent topic in the work of the Israeli-Arab writer Sayed Kashua. In the last couple of years, Sayed Kashua has moved away from writing about the prejudice expressed by his own Israeli Muslim community towards the Israeli Jewish population to focus his attention instead on the prejudice shown by Jews against Arabs in Israel. Self-criticism has always been a hallmark of Sayed Kashua's work so this shift indicates a significant change in the columnist's perception of his own society. Based on a survey of various issues relating to Israeli society, such as the law, the educational system and language, as well as a theoretical review of authors who observe a mutual alienation of Arabs and Jews in Israel, this article analyses several of Sayed Kashua's recent columns in the Israeli newspaper Haaretz. It also investigates how the author understands prejudice and, in a singular and surprising way, expresses his concerns and solutions to this problem

Experiencing the armed struggle : the Soweto generation and after
No full textIncludes bibliographical references (p. 354-369).This study explores the experiences of the rank-and-file soldiers of Umkhonto we Sizwe and the Azanian People's Liberation Anny. Extensive interviews by the author and other researchers reveal the voices of the soldiers themselves. The African National Congress and Pan African Congress archives at the University of the Western Cape and the University of Fort Hare supplement and verify these oral testimonies, as do some published sources. Most previously published materials about the armed struggle against apartheid have already focused on diplomacy, strategy and tactics, operations, leadership, and human rights abuses to the neglect of the soldiers' actual experiences. This study complements these with significant new oral history materials from the Soweto generation of soldiers and their successors. When dealing with MK, many authors have documented issues of the camp structure in Angola, and operations inside South Africa, so much of this detail is only addressed briefly, leaving space to explore the soldiers' experiences. In the case of APLA, very little has been written on its history, and more detail is provided on these subjects. This study therefore deals with the soldiers' politicisation and motivation for joining the armed struggle, their experiences in leaving South Africa and training in exile, the crises in exile which limited their effectiveness for a time, their return to fight in South Africa, and their difficulties in the "new" South Africa. These materials reveal that vast problems remain facing these veterans of the struggle against apartheid, and that they have the potential, if properly supported and employed, to contribute substantially to the development of present day South Africa. Conversely, if their neglect continues, they also have the potential to bring vast harm to the country. Further use of the investigative tools of oral history, especially if extended to the former soldiers' vernacular languages, is necessary to augment the history of South Africa, and these soldiers' contributions
Tão dúbio, tão coerente: forma e conteúdo nas crônicas jornalísticas de Sayed Kashua
No full textEste artigo consiste na análise de duas crônicas jornalísticas do escritor árabe-israelense Sayed Kashua publicadas no jornal israelense Haaretz. Estes textos são selecionados devido à sua riqueza de conteúdo e pelo uso de estratégias retóricas, tais como a autoironia e o sarcasmo, para expor os conflitos pelos quais passa o “eu do cronista” retratado pelo autor. Este estudo tem como base os Estudos Culturais e os Novos Paradigmas Literários, ferramentas que permitem o estudo das crônicas jornalísticas como textos literários. Nestas crônicas, de uma maneira despretensiosa, partindo de experiências subjetivas e de temas familiares, com autoironia e tom satírico, Kashua reporta as experiências de um árabe israelense que vive num embate em torno de suas duplas lealdades e ideologias conflitantes, refletindo uma negociação entre sua etnicidade e sua nacionalidade. A crônica, neste contexto, é considerada o local apropriado para a escrita de Kashua: a ambiguidade do gênero é similar à necessidade de quebras de dualidades na sociedade israelense para entendermos e convivermos com o “eu do cronista” de Sayed Kashua. So dubious, so coherent: form and content in Sayed Kashua´s journalistic chronicles - Abstract: This paper consists of the literary analysis oftwo journalistic chronicles written in Hebrew by the Muslim Arab Israeli author Sayed Kashua published in the Israeli newspaper Haaretz. These texts are selected due to their richness of content and use of rhetorical strategies such as self-irony and sarcasm to expose the conflicts through which the “I of the chronicler” portrayed by the author goesthrough. This analysis will rely on theoretical assumptions of Cultural Studies and the “New literary paradigms”, tools that will enable us to study the journalistic chronicle as a literary text. In these chronicles, in a non-pretentious way, coming from the subjective experiences and family topics, with self-irony and in a satirical way, Kashua reports the experiences of an Israeli Arab who lives in a clash over his dual loyalty and conflicting ideologies, reflecting a negotiation between his ethnicity and his nationality. The chronicle, in this context, is considered the appropriate location for Kashua’s writings: the ambiguity of the literary genre is similar to the necessity of breaking dualities in Israeli society to understand and to be acquainted with the “I of the chronicler” of Sayed Kashua
Distributed chance-constrained model predictive control for condition-based maintenance planning for railway infrastructures
No full textWe develop a Model Predictive Control (MPC) approach for condition-based maintenance planning under uncertainty for railway infrastructure systems composed of multiple components. Piecewise-affine models with uncertain parameters are used to capture both the nonlinearity and uncertainties in the deterioration process. To keep a balance between robustness and optimality, we formulate the MPC optimization problem as a chance-constrained problem, which ensures that the constraints, e.g., bounds on the degradation level, are satisfied with a given probabilistic guarantee. Two distributed algorithms, one based on Dantzig-Wolfe decomposition and the other derived from a constraint-tightening technique, are proposed to improve the scalability of the MPC approach. Computational experiments show that the distributed method based on Dantzig-Wolfe decomposition performs the best in terms of computational time and convergence to global optimality. By comparing the chance-constrained MPC approaches with deterministic approach, and traditional time-based maintenance approach, we show that despite their high computational requirements, chance-constrained MPC approaches are cost-efficient and robust in the presence of uncertainties.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.Team Bart De SchutterRailway EngineeringDelft Center for Systems and Contro
Numerical Investigation of Thermal-Flow Characteristics in Heat Exchanger with Various Tube Shapes
No full textIn this study, eight configurations of oval and flat tubes in annular finned-tube thermal devices are examined and compared with the conventional circular tube. The objective is to assess the effect of tube flatness and axis ratio of the oval tube on thermal-flow characteristics of a three-row staggered bank for Re (2600 ≤ Re ≤ 10,200). It has been observed that the thermal exchange rate and Colburn factor increase according to the axis ratio and the flatness, where O1 and F1 provide the highest values. O1 produces the lowest friction factor values of all the oval tubes at all Re, and F4 gives 13.2–18.5% less friction than the other tube forms. In terms of performance evaluation criterion, all of the tested tubes outperformed the conventional circular tube (O5), with O1 and F1 obtaining the highest values. The global performance criterion of O1 has been found to be 9.6–45.9% higher as compared to the other oval tube geometries at lower values of Re, and the global performance criterion increases with the increase in flatness. The F1 tube shape outperforms all the examined tube designs; thus, this tube geometry suggests that it be used in energy systems
Culpa e sátira no divã: duas crônicas jornalisticas de Sayed Kashua
No full textNeste artigo, são analisadas duas crônicas jornalísticas do escritor árabe israelense Sayed Kashua publicadas no jornal Haaretz. Nelas, um embate entre uma sociedade radical e racista e a herança ética e moral dos idealizadores do Sionismo, segundo a qual os árabes receberiam direitos iguais aos da popula-ção judaica, encontram-se como pano de fundo de histórias tão satíricas quanto trágicas. O preconceito contra o árabe permeia as situações pelas quais passa o eu do cronista, mas cabe ao leitor decidir se ele é apenas uma possibilidade que poderia ser vivenciada, se ele de fato está presente nas relações do árabe na sociedade judaico israelense à sua volta ou se estas são alternativas que se complementam.In this paper, I analyze two journalistic chronicles written by the Israeli Arab author Sayed Kashua published in Israeli newspaper Haaretz. In these texts, a clash between a radical and racist society and the ethics and moral heritage of the creators of Zionism, according to which the Arabs would receive equal rights as the Jewish population, are the background of these stories which are as satirical as tragic. The prejudice against the Arab population permeates the situations in which “I of the chronicler” live, but it is up to the reader to decide if it is just a possibility that could be experienced, if they actually permeate the Arab relations in Israeli Jewish society or if these are alternatives that are complementary
