Cosmic Clowns : Convention, Invention, and Inversion in the Yaqui Easter Ritual

Cosmic Clowns: Convention, Invention, and Inversion in the Yaqui Easter Ritual is an ethnographic study of masked clown figures called Chapayekas. They represent Judas and the Roman soldiers in the Passion play that forms the narrative core of the Easter ritual of the Yaquis, an indigenous group in Sonora, Mexico. The study looks at how the Chapayeka is created as a ritual figure, how their performance is constructed, and what the part of the clown is in the dynamics of the ritual. The material was gathered over three periods of anthropological fieldwork in Cócorit, Sonora during Easter in 2004, 2006 and 2007. The Chapayeka masks portray foreigners, animals, mythological figures, and even figures from television and movies. They combine two kinds of performance: they perform set, conventional actions, and improvise and invent new ones. This creates dialectics of invention and convention that allow the figure to mediate between the ritual and its context and different kinds of beings within the Yaqui cosmology. The conventional side of their performance is a cycle of death and rebirth that is an inversion of the cycle of Jesus. Through invention, they separate themselves from the other performers and make themselves powerful. Alternation between the two modes enhances that power and brings it into the conventions of the ritual; ultimately the Chapayekas revitalize the entire ritual. The study finds that the clowns are extremely important to the continuity of both ritual and culture, as the combination of continuity and change, convention and invention, is what makes it possible to recreate the conventions of Yaqui culture as powerful and compelling in various contexts. Another factor is the prevalence of dialectical mediation, which relates concepts by defining them against each other as opposites, and makes it possible to cross a boundary while keeping it intact. Clowns embody and create dialectics to mediate boundaries while guarding against relativization, the disappearance of distinctions. The Chapayekas create and constitute boundaries between the self and other, microcosm and macrocosm, sacred and profane. The study argues that all clown and trickster figures are characterized by constantly alternating between invention and convention; this is what connects them to the collective and moral aspect of culture and, at the same time, makes them unpredictable and powerful. It is possible to do justice to the opposed aspects of these ambiguous and paradoxical figures by taking into account the different foundations and contextual effects of the different modes of symbolization.

Choosing the Arranged One, Arranging the Chosen One – Imagining an Indian Modernity: Reconciling Love, Marriage and Family On and Off the Screen

This is a study on the changing practices of kinship in Northern India. The change in kinship arrangements, and particularly in intermarriage processes, is traced by analysing the reception of Hindi popular cinema. Films and their role and meaning in people´s lives in India was the object of my research. Films also provided me with a methodology for approaching my other subject-matters: family, marriage and love. Through my discussion of cultural change, the persistence of family as a core value and locus of identity, and the movie discourses depicting this dialogue, I have looked for a possibility of compromise and reconciliation in an Indian context. As the primary form of Indian public culture, cinema has the ability to take part in discourses about Indian identity and cultural change, and alleviate the conflicts that emerge within these discourses. Hindi popular films do this, I argue, by incorporating different familiar cultural narratives in a resourceful way, thus creating something new out of the old elements. The final word, however, is the one of the spectator. The “new” must come from within the culture. The Indian modernity must be imaginable and distinctively Indian. The social imagination is not a “Wild West” where new ideas enter the void and start living a life of their own. The way the young women in Dehra Dun interpreted family dramas and romantic movies highlights the importance of family and continuity in kinship arrangements. The institution of arranged marriage has changed its appearance and gained new alternative modes such as love cum arranged marriage. It nevertheless remains arranged by the parents. In my thesis I have offered a social description of a cultural reality in which movies act as a built-in part. Movies do not work as a distinct realm, but instead intertwine with the social realities of people as a part of a continuum. The social imagination is rooted in the everyday realities of people, as are the movies, in an ontological and categorical sense. According to my research, the links between imagination and social life were not so much what Arjun Appadurai would call global and deterritorialised, but instead local and conventional.

Design issues and caching strategies for CD-ROM based multimedia storage

CD-ROMs have proliferated as a distribution media for desktop machines for a large variety of multimedia applications (targeted for a single-user environment) like encyclopedias, magazines and games. With CD-ROM capacities up to 3 GB being available in the near future, they will form an integral part of Video on Demand (VoD) servers to store full-length movies and multimedia. In the first section of this paper we look at issues related to the single- user desktop environment. Since these multimedia applications are highly interactive in nature, we take a pragmatic approach, and have made a detailed study of the multimedia application behavior in terms of the I/O request patterns generated to the CD-ROM subsystem by tracing these patterns. We discuss prefetch buffer design and seek time characteristics in the context of the analysis of these traces. We also propose an adaptive main-memory hosted cache that receives caching hints from the application to reduce the latency when the user moves from one node of the hyper graph to another. In the second section we look at the use of CD-ROM in a VoD server and discuss the problem of scheduling multiple request streams and buffer management in this scenario. We adapt the C-SCAN (Circular SCAN) algorithm to suit the CD-ROM drive characteristics and prove that it is optimal in terms of buffer size management. We provide computationally inexpensive relations by which this algorithm can be implemented. We then propose an admission control algorithm which admits new request streams without disrupting the continuity of playback of the previous request streams. The algorithm also supports operations such as fast forward and replay. Finally, we discuss the problem of optimal placement of MPEG streams on CD-ROMs in the third section.

The collective dynamics of self-propelled particles

We propose a method for the dynamic simulation of a collection of self-propelled particles in a viscous Newtonian fluid. We restrict attention to particles whose size and velocity are small enough that the fluid motion is in the creeping flow regime. We propose a simple model for a self-propelled particle, and extended the Stokesian Dynamics method to conduct dynamic simulations of a collection of such particles. In our description, each particle is treated as a sphere with an orientation vector p, whose locomotion is driven by the action of a force dipole Sp of constant magnitude S0 at a point slightly displaced from its centre. To simplify the calculation, we place the dipole at the centre of the particle, and introduce a virtual propulsion force Fp to effect propulsion. The magnitude F0 of this force is proportional to S0. The directions of Sp and Fp are determined by p. In isolation, a self-propelled particle moves at a constant velocity u0 p, with the speed u0 determined by S0. When it coexists with many such particles, its hydrodynamic interaction with the other particles alters its velocity and, more importantly, its orientation. As a result, the motion of the particle is chaotic. Our simulations are not restricted to low particle concentration, as we implement the full hydrodynamic interactions between the particles, but we restrict the motion of particles to two dimensions to reduce computation. We have studied the statistical properties of a suspension of self-propelled particles for a range of the particle concentration, quantified by the area fraction φa. We find several interesting features in the microstructure and statistics. We find that particles tend to swim in clusters wherein they are in close proximity. Consequently, incorporating the finite size of the particles and the near-field hydrodynamic interactions is of the essence. There is a continuous process of breakage and formation of the clusters. We find that the distributions of particle velocity at low and high φa are qualitatively different; it is close to the normal distribution at high φa, in agreement with experimental measurements. The motion of the particles is diffusive at long time, and the self-diffusivity decreases with increasing φa. The pair correlation function shows a large anisotropic build-up near contact, which decays rapidly with separation. There is also an anisotropic orientation correlation near contact, which decays more slowly with separation. Movies are available with the online version of the paper.

How to run a campaign: Optimal control of SIS and SIR information epidemics

Information spreading in a population can be modeled as an epidemic. Campaigners (e.g., election campaign managers, companies marketing products or movies) are interested in spreading a message by a given deadline, using limited resources. In this paper, we formulate the above situation as an optimal control problem and the solution (using Pontryagin's Maximum Principle) prescribes an optimal resource allocation over the time of the campaign. We consider two different scenarios-in the first, the campaigner can adjust a direct control (over time) which allows her to recruit individuals from the population (at some cost) to act as spreaders for the Susceptible-Infected-Susceptible (SIS) epidemic model. In the second case, we allow the campaigner to adjust the effective spreading rate by incentivizing the infected in the Susceptible-Infected-Recovered (SIR) model, in addition to the direct recruitment. We consider time varying information spreading rate in our formulation to model the changing interest level of individuals in the campaign, as the deadline is reached. In both the cases, we show the existence of a solution and its uniqueness for sufficiently small campaign deadlines. For the fixed spreading rate, we show the effectiveness of the optimal control strategy against the constant control strategy, a heuristic control strategy and no control. We show the sensitivity of the optimal control to the spreading rate profile when it is time varying. (C) 2014 Elsevier Inc. All rights reserved.

Query Click and Text Similarity Graph for Query Suggestions

Query suggestion is an important feature of the search engine with the explosive and diverse growth of web contents. Different kind of suggestions like query, image, movies, music and book etc. are used every day. Various types of data sources are used for the suggestions. If we model the data into various kinds of graphs then we can build a general method for any suggestions. In this paper, we have proposed a general method for query suggestion by combining two graphs: (1) query click graph which captures the relationship between queries frequently clicked on common URLs and (2) query text similarity graph which finds the similarity between two queries using Jaccard similarity. The proposed method provides literally as well as semantically relevant queries for users' need. Simulation results show that the proposed algorithm outperforms heat diffusion method by providing more number of relevant queries. It can be used for recommendation tasks like query, image, and product suggestion.

Using Earth Deformation Caused by Surface Mass Loading to Constrain the Elastic Structure of the Crust and Mantle

Surface mass loads come in many different varieties, including the oceans, atmosphere, rivers, lakes, glaciers, ice caps, and snow fields. The loads migrate over Earth's surface on time scales that range from less than a day to many thousand years. The weights of the shifting loads exert normal forces on Earth's surface. Since the Earth is not perfectly rigid, the applied pressure deforms the shape of the solid Earth in a manner controlled by the material properties of Earth's interior. One of the most prominent types of surface mass loading, ocean tidal loading (OTL), comes from the periodic rise and fall in sea-surface height due to the gravitational influence of celestial objects, such as the moon and sun. Depending on geographic location, the surface displacements induced by OTL typically range from millimeters to several centimeters in amplitude, which may be inferred from Global Navigation and Satellite System (GNSS) measurements with sub-millimeter precision. Spatiotemporal characteristics of observed OTL-induced surface displacements may therefore be exploited to probe Earth structure. In this thesis, I present descriptions of contemporary observational and modeling techniques used to explore Earth's deformation response to OTL and other varieties of surface mass loading. With the aim to extract information about Earth's density and elastic structure from observations of the response to OTL, I investigate the sensitivity of OTL-induced surface displacements to perturbations in the material structure. As a case study, I compute and compare the observed and predicted OTL-induced surface displacements for a network of GNSS receivers across South America. The residuals in three distinct and dominant tidal bands are sub-millimeter in amplitude, indicating that modern ocean-tide and elastic-Earth models well predict the observed displacement response in that region. Nevertheless, the sub-millimeter residuals exhibit regional spatial coherency that cannot be explained entirely by random observational uncertainties and that suggests deficiencies in the forward-model assumptions. In particular, the discrepancies may reveal sensitivities to deviations from spherically symmetric, non-rotating, elastic, and isotropic (SNREI) Earth structure due to the presence of the South American craton.

Os dois Orfeus, representações da paisagem favela no cinema: o olhar estrangeiro e o olhar de pertencimento

Esta dissertação apresenta uma reflexão focada na análise geográfico-cultural da paisagem favela na cidade do Rio de Janeiro e em sua representação no cinema, pelo discurso fílmico presente nas obras Orfeu negro (1959), de Marcel Camus e Orfeu (1999) de Carlos Diegues. Tal discurso emerge como instrumento de compreensão do processo evolutivo que gerou uma espécie de linhagem da favela na cidade. Os quarenta anos passados entre os dois Orfeus e as paisagens reais e ficcionais, da favela neles presentes espelham um rico contínuo espaço-tempo. Quarenta anos de mudanças na história do mundo, da cultura, da cidade, da favela e das técnicas do cinema possibilitaram a gestação de duas obras fílmicas diferentes, inclusive em função dos olhares estrangeiro e de pertencimento que balizam a visão de seus respectivos diretores. A nova geografia cultural, com sua feição interdisciplinar, fornece instrumental apropriado para estudar, analisar e entender a complexa teia de relações políticas, econômicas, sociais e culturais presentes na paisagem favela, hoje um dos signos mais conhecidos da cidade do Rio de Janeiro polo da dualidade entre a inclusão e a exclusão social.

Din, don, don: Mestre Paraná e o Grupo Folclórico de Capoeira São Bento Pequeno (1950-1960)

Este trabalho questiona a construção da memória e da história da capoeira no Rio de Janeiro na segunda metade do século XX. A capoeira como manifestação cultural é tema de um crescente número de trabalhos artísticos, desde peças de teatro, filmes para o cinema, bem como de ações do governo, com destaque para seu tombamento como "patrimônio imaterial da cultura brasileira". É praticada em mais de 150 países, onde se apresenta como mais uma das identidades dos brasileiros no exterior. No Rio de Janeiro, deixou marcas profundas na memória do século XIX, representada em documentos variados do Estado e nas letras dos intelectuais da época. História que tem sido pesquisada por autores que já assistem suas obras sendo consagradas pelo crescente número de interessados no tema. Em contrapartida, a história recente desta prática ainda é assunto raro na historiografia, bem como nas demais disciplinas das ciências humanas. Assim, através da pesquisa etnográfica com o Grupo Folclórico de Capoeira São Bento Pequeno, escola de capoeira de Mestre Paraná, questionamos esta lacuna no conhecimento acadêmico, bem como seu reflexo na formação das "tradições" da capoeira no Rio de Janeiro. O Grupo São Bento Pequeno esteve em atividade nas décadas de 1950 e 1960, período de retomada do crescimento da capoeira no Rio de Janeiro.

A arte de rir da morte: em Shakespeare e em Camões

Esta pesquisa tem por objetivo apontar os recursos criativos, usados por Shakespeare e Camões, para a construção de cenas, que têem como finalidade provocar o riso nos expectadores. Escolhemos três comédias de Shakespeare (Noite de Reis, A comédia dos erros, Sonho de uma noite de verão) para fazer uma leitura comparativa com as três comédias escritas por Camões (Filodemo, El Rei Seleuco e Anfitrião). Constatamos que, apesar da existência de uma variedade de procedimentos técnicos para a produção do riso, os autores recorreram aos mesmos recursos criativos: naufrágios, personagens com identidades trocadas, gêmeos que são confundidos e encenação de uma peça dentro de outra peça. Esses recursos são ferramentas com a função de criar um anteparo diante do horror da morte, o que constitui um processo de defesa do homem diante do seu inexorável destino. Nesse sentido, a comédia é uma das vias pela qual o homem ri da morte

Noite fantástica: um percurso pelos estudos críticos e historiográficos sobre a obra Noite na taverna, de Álvares de Azevedo

Diversos críticos enfatizaram a vertente de Noite na taverna, de Álvares de Azevedo, obra que se consagrou, portanto, como uma narrativa pertencente ao gênero fantástico, apesar de não corresponder plenamente à concepção do gênero desenvolvida por Tzvetan Todorov, em Introdução à literatura fantástica subsídio fundamental para os estudos da ficção insólita. "Fantástica"!, "sobrenatural", "de horror", "tétrica", "sombria", "macabra", "monstruosa", "dantesca", "simbolista avant la lettre", "gótica", "satanista", "byroniana" são alguns dos termos empregados pela crítica nos principais estudos publicados acerca da obra. Trata-se de uma multiplicidade de classificações que, no entanto, não a caracterizam adequadamente e só demonstram a dificuldade de definir-lhe o gênero. Refletindo sobre tais aspectos e partindo dos principais estudos críticos produzidos sobre a obra desde sua primeira edição, consideramos a pertinência de a classificarmos como integrante do gênero fantástico. Procura-se ainda, após minuciosa leitura destes estudos, identificar os momentos da história e da crítica literária brasileira em que Noite na taverna foi classificada com termos que a associaram a uma forma de literatura incomum no Brasil nacionalista do século XIX.
