This thesis is concerned with the development and implications of a critical mode of inquiry into the architectural environment as it is articulated in the photographic projects of German artists Eric Mendelsohn (1887-1953) and Wolfgang Tillmans (b. 1968). These projects are understood as being in opposition to a conventional subordination of photography to architecture. The architectural photograph has consistently been reduced to the role of a tool in the proliferation of structures of global capitalism, facilitating the rise of homogeneous and disconnected built environments. Through an examination and comparison of Mendelsohn’s 1926 book Amerika: Bilderbuch eines Architekten with Tillmans' 2014 video installation Book for Architects, this thesis argues that the visual strategies employed in these works reflect similar concerns regarding the state of architectural practice, providing alternative avenues of inquiry for architects, and highlighting the necessity for deeper engagement with the phenomenological qualities of the architectural environment.

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1993. / Includes bibliographical references (leaves 176-186). / This paper examines the creative persona of Erich Mendelsohn's seemingly incompatible bodies of architecture in Europe, Palestine and the U.S. The limits of existing formal analysis to explain his architectural shifts were the impetus for investigating the architectural position that facilitated not only Mendelsohn's iconic architecture in Germany, but its appropriation to Palestine as well. Beside his artistic ambiance, is also Mendelsohn's religious faith, national identity and political convictions. Mendelsohn was part of the Jewish post-assimilated generation in Germany - this experience is extended by Mendelsohn to the art of building, which was facilitated intellectually by Martin Buber's (early) teaching about the creative Jewish yearning for unity. The paper focus on how Mendelsohn's consistent architectural and political position discloses itself first in the industrial West (Germany), where it engaged the striving architectural debated of the period, and then in the Orient. In Palestine, where he took part in the "cultural Zionist" agenda, he remolded Modern Architecture into a non- Western country. / by Alona Nitzan-Shiftan. / M.S.

INTRODUÇÃO: na reabilitação da disfagia faríngea, a manobra de Mendelsohn (MM) é a única descrita como efetiva para o trabalho de elevação da laringe e seqüente abertura do segmento faringo-esofágico, desde que executada corretamente. OBJETIVO: avaliar a eficácia do uso do biofeedback eletromiográfico no processo de treinamento para correta execução da manobra de Mendelsohn em portadores de Doença de Machado-Joseph (DMJ), com disfagia alta. CASUÍSTICA: participaram deste estudo 20 indivíduos sem queixas quanto à deglutição e 20 disfágicos, portadores de DMJ, que se equiparavam em termos de distribuição de sexos e média de idade, tinham cognitivo preservado, e foram separados em grupos: A e C, de disfágicos, e B e D, de controles. MÉTODOS: todos foram submetidos a anamnese dirigida, avaliação clínica da deglutição e a eletromiografia para verificação do tempo de sustentação da elevação da laringe, repetida depois de treinamento para correta execução da manobra de Mendelsohn, feito com (grupos A e B) ou sem (grupos C e D) a utilização do biofeedback eletromiográfico.Dificuldades relacionadas à realização da MM foram observadas diretamente e relatadas em resposta a questionário. RESULTADOS: a comparação dos disfágicos com os controles não evidenciou diferenças marcantes quanto à avaliação clínica da fase oral da deglutição, pois os doentes demonstravam apenas déficits quanto a protrusão, retração e tônus da língua. Entretanto, quanto à fase faríngea, mostraramse diferenças mais significativas, com os disfágicos apresentando, à deglutição de líquidos e sólidos, estase faríngea, acompanhada de tosse e/ou engasgo e penetração e/ou aspiração, alterações ausentes nos controles. Houve significante aumento do tempo de sustentação da elevação da laringe, de controles e pacientes, à deglutição de saliva, durante a realização da manobra de Mendelsohn, após o treinamento, principalmente se conduzido com suporte de biofeedback eletromiográfico. O mesmo ocorreu com a deglutição de iogurte, pastoso, consistência preferida pelos pacientes. Os pacientes do grupo A chegaram a atingir o mesmo desempenho que seus controles (grupo B), à realização da MM. À observação direta de dificuldades encontradas durante a realização da manobra, notou-se dificuldade para sustentar a elevação da laringe. Quando os indivíduos foram inquiridos a respeito, destacou-se dificuldade de entendimento da MM. De significante, extraiu-se, à observação direta e ao inquérito, que os pacientes têm mais expressivas dificuldades de controle respiratório durante a realização da MM do que os controles. CONCLUSÕES: 1. o treinamento orientado, verbal e gestual, para a correta execução da MM, é capaz, por si só, de aumentar o tempo de sustentação da elevação da laringe em portadores de DMJ e controles; 2. o biofeedback eletromiográfico agrega valor ao treinamento, promovendo ainda maior tempo de sustentação da elevação da laringe, à execução da MM, em portadores de DMJ, que atingem índices semelhantes aos dos controles, na deglutição de saliva e de pastoso; 3. os portadores de DMJ apresentam freqüentemente dificuldade de controle respiratório, sem repercussão clínica, durante a aplicação da MM. / Introduction: In the rehabilitation of pharyngeal dysphagia, the Mendelsohn maneuver (MM) is the only technique described as effective for elevating the larynx with subsequent opening of the esophageal-pharyngeal segment, provided it is correctly performed. Objective: To evaluate the efficacy of electromyographic biofeedback for training of the Mendelsohn maneuver in Machado-Joseph patients (MJD) with high dysphagia. Case Studies: Forty individuals participated in this study, including twenty with no complaints of deglutition and twenty MJD dysphagic patients , who were all similar in terms of gender distribution, average age, and cognitive function. Method: The medical history of each patient was reviewed. Each subject underwent a clinical evaluation of deglutition, as well as electromyography to determine the amount of time for which larynx elevation was sustained. Electromyography was repeated following achievement of the correct performance of MM. Training for MM was completed with (groups A and B) or without (groups C and D) electromyographic biofeedback. Difficulties related to performance of MM were observed directly and reported through the completion of a questionnaire. Results: Comparison between dysphagic patients and controls did not reveal significant differences with respect to the clinical evaluation of the oral phase of deglutition, since afflicted patients only demonstrated deficits related to the protrusion, retraction and tonus of the tongue. However, significant differences were observed with respect to the pharyngeal phase. Dysphagic patients presented with pharyngeal stasis during deglutition of liquids and solids, accompanied by coughing and/or choking as well as penetration and/or aspiration; these symptoms were absent in the controls. After training, there was a significant increase during MM in the time of larynx elevation as well as in the deglutition of saliva in both controls and patients. The time of larynx elevation was further increased when training was conducted with electromyographic biofeedback support. Similar results were found for the deglutition of yogurt, which has a pasty consistency preferred by the patients. Group A patients performed MM at the same level of competency as controls (group B). During direct observation, difficulties in sustaining the elevation of the larynx were noted. Questioning of the individuals experiencing difficulty revealed a lack of understanding with respect to MM. Specifically, it was determined that patients had more pronounced difficulty in respiratory control during MM as compared to normal controls. Conclusions: 1. Guided training, both verbal and gestural, for correct performance of the MM can increase the time of sustained larynx elevation in MJD patients and controls; 2. The use of electromyographic biofeedback during training further increases the time of sustained larynx elevation in MJD patients, allowing them to reach indexes similar to those of controls with respect to deglutition of saliva and semi-fluids; 3. Carriers of MJD frequently have difficulty in respiratory control, but without clinical repercussions, during the application of MM.

Cette étude propose d’explorer les œuvres de Jonathan Safran Foer, Daniel Mendelsohn, et Art Spiegelman, à travers la notion de trace, principe fondateur de l’esthétique et de l’éthique des écritures de l’après-Shoah. L’expérience lacunaire de ces « générations d’après » implique la présence d’une « postmémoire », dont le caractère « différé » sollicite le travail de l’imagination et informe la démarche créatrice de ces artistes et écrivains de l’après, qui reconstruisent le passé de leurs familles. Ces récits de la hantise sont marqués par une « mémoire trouée », et découlent souvent d’une rupture de la filiation, donc d’une défaillance de la transmission. Engagés dans une quête de savoir, narrateurs et protagonistes interrogent l’événement à partir de traces matérielles, ainsi qu’au travers de retours, réels et imaginaires, sur les lieux de l’origine. Ces récits sont composés de matériaux hétérogènes qui créent des ruptures visuelles, et sont informés par divers dérèglements temporels : désordres, disruptions chronologiques, latence et répétition – tous symptomatiques de l’après-coup du trauma. Ces textes postmémoriels posent enfin la question de l’éthique de la représentation. Performativité de la langue, fictionnalisation de l’Histoire, et enjeux de la transmission sont au cœur de ces œuvres en devenir, et interrogent l’éthique de la responsabilité de leurs auteurs, entre passation et travail de deuil. / This study explores the works of Jonathan Safran Foer, Daniel Mendelsohn, and Art Spiegelman through the notion of trace, the founding principle of the aesthetics and ethics of post-Holocaust writing. The incomplete knowledge of these “post-Holocaust generations” implies the presence of a “postmemory”, the “deferred” nature of which requires the imagination to be put to work and informs the creative approach of these post-Holocaust artists and writers, reconstructing their family’s past. These haunting narratives are marked by a “memory shot through with holes” and are often the result of a break in the bond of filiation, and therefore a hiatus of transmission. Having embarked on a quest for knowledge, narrators and protagonists examine the event through material traces, as well as real or imaginary returns to their places of origin. These narratives are made up of heterogeneous elements which create visual ruptures and are informed by various temporal disruptions: disorders, chronological breaks, latency and repetition – all symptomatic of the deferred action of trauma. Finally, these postmemorial texts raise the issue of the ethics of representation. The performativity of language, the fictionalization of History, and the issue of transmission are at the heart of these works in the making, and ethically question their authors’ responsibility, between transfer and the work of mourning.

It is well known that for any Steiner triple system (STS) one can define a binary operation · upon its base set by assigning x·x = x for all x and x·y = z, where z is the third point in the block containing the pair {x, y}. The same can be done for Mendelsohn triple systems (MTS), directed triple systems (DTS) as well as hybrid triple systems (HTS), where (x, y) is considered to be ordered. In the case of STSs and MTSs the operation yields a quasigroup, however this is not necessarily the case for DTSs and HTSs. A DTS or an HTS which induces a quasigroup is said to be Latin. The quasigroups associated with STSs and MTSs satisfy the flexible law x · (y · x) = (x · y) · x but those associated with Latin DTSs and Latin HTSs need not. A DTS or an HTS is said to be pure if when considered as a twofold triple system it contains no repeated blocks. This thesis focuses on the study of Latin DTSs and Latin HTSs, in particular it aims to examine flexibility, purity and other related properties in these systems. Latin DTSs and Latin HTSs which admit a cyclic or a rotational automorphism are also studied. The existence spectra of these systems are proved and enumeration results are presented. A smaller part of the thesis is then devoted to examining the size of the centre of a Steiner loop and the connection to...

Le présent mémoire a pour but d’examiner les romans Le Monarque des ombres (2017) de Javier Cercas et The Lost (2006) de Daniel Mendelsohn afin de voir comment leurs auteurs y produisent du savoir sur l’histoire, sur la mémoire familiale et sur la mémoire collective. Les deux auteurs écrivent sur leurs grands-oncles : le grand-oncle de Cercas est mort en Espagne, du côté franquiste, pendant la guerre civile (1936-1939). Celui de Mendelsohn est assassiné, avec sa femme et ses quatre filles, en Pologne en 1942 au cours de la Shoah par balles. Dans leurs textes, Cercas et Mendelsohn restituent les étapes des recherches qu’ils ont menées pour retrouver des informations sur les circonstances de la vie et de la mort de leurs grands-oncles. Afin de réfléchir à la nature du geste littéraire qu’ils proposent à l’égard de l’histoire et de la mémoire familiale et collective, nous effectuons dans un premier temps un état des lieux des différents débats académiques récents sur les rapports histoire-littérature. Nous poursuivons ensuite en analysant les procédés métatextuels et autoréflexifs déployés par les deux auteurs dans leurs textes, de manière à voir comment ces procédés reflètent les enjeux éthiques, méthodologiques et épistémologiques de leur démarche et la complexité du savoir qu’ils produisent. Finalement, nous étudions l’usage fait par Cercas et Mendelsohn des archives dans leurs textes. Ce faisant, nous pouvons voir comment les archives photographiques, notamment, sont médiatrices du rapport identitaire et mémoriel qu’entretiennent les deux auteurs avec leurs grands-oncles. / This dissertation aims to examine the novels Lord of All the Dead by Javier Cercas and The Lost by Daniel Mendelsohn to see how their authors produce knowledge on history and on familial and collective memory. Both writers focus their novels on their great-uncles: Cercas’ great-uncle died in the Spanish civil war (1936-1939) fighting with the Francoist army. Mendelsohn’s great-uncle was killed in Poland in 1942 during the Shoah by bullets with his wife and four daughters. In their texts, Cercas and Mendelsohn reconstruct the different stages of their researches to find out about the lives and deaths of their great-uncles. In order to reflect on the literary texts they wrote and its relations to history and familial and collective memory, we first make a summary of some of the recent debates in the academic field about the relationship between literature and history. We go on by analyzing the metatextual and self-reflexive devices both authors use, to see how they reflect the ethical, methodological and epistemological issues of their approach and the complexity of the knowledge they produce. Finally, we look at how Cercas and Mendelsohn use archives in their texts. By doing so, we can see how archives, mostly photographic archives, are used as devices that reflect the identity and memorial link that connects both authors with their great-uncles.
