In-situ sediment temperature and pore water chloride concentration at pockmarks of the Nigerian continental margin

A joint research expedition between the French IFREMER and the German MARUM was conducted in 2011 using the R/V 'Pourquoi pas?' to study gas hydrate distributions in a pockmark field (1141-1199 m below sea surface) at the continental margin of Nigeria. The seafloor drill rig MeBo of MARUM was used to recover sediments as deep as 56.74 m below seafloor. The presence of gas hydrates in specific core sections was deduced from temperature anomalies recorded during continuous records of infrared thermal scanning and anomalies in pore water chloride concentrations. In situ sediment temperature measurements showed elevated geothermal gradients of up to 258 °C/km in the center of the so-called pockmark A which is up to 4.6 times higher than that in the background sediment (72 °C/km). The gas hydrate distribution and thermal regime in the pockmark are largely controlled by the intensity, periodicity and direction of fluid flow. The joint interaction between fluid flow, gas hydrate formation and dissolution, and the thermal regime governs pockmark formation and evolution on the Nigerian continental margin.

Si and SixGe1-x NWs studied by Raman spectroscopy

Group IV nanostructures have attracted a great deal of attention because of their potential applications in optoelectronics and nanodevices. Raman spectroscopy has been extensively used to characterize nanostructures since it provides non destructive information about their size, by the adequate modeling of the phonon confinement effect. The Raman spectrum is also sensitive to other factors, as stress and temperature, which can mix with the size effects borrowing the interpretation of the Raman spectrum. We present herein an analysis of the Raman spectra obtained for Si and SiGe nanowires; the influence of the excitation conditions and the heat dissipation media are discussed in order to optimize the experimental conditions for reliable spectra acquisition and interpretation.

Estimation of functional connectivity from electromagnetic signals and the amount of empirical data required

An increasing number of neuroimaging studies are concerned with the identification of interactions or statistical dependencies between brain areas. Dependencies between the activities of different brain regions can be quantified with functional connectivity measures such as the cross-correlation coefficient. An important factor limiting the accuracy of such measures is the amount of empirical data available. For event-related protocols, the amount of data also affects the temporal resolution of the analysis. We use analytical expressions to calculate the amount of empirical data needed to establish whether a certain level of dependency is significant when the time series are autocorrelated, as is the case for biological signals. These analytical results are then contrasted with estimates from simulations based on real data recorded with magnetoencephalography during a resting-state paradigm and during the presentation of visual stimuli. Results indicate that, for broadband signals, 50–100 s of data is required to detect a true underlying cross-correlations coefficient of 0.05. This corresponds to a resolution of a few hundred milliseconds for typical event-related recordings. The required time window increases for narrow band signals as frequency decreases. For instance, approximately 3 times as much data is necessary for signals in the alpha band. Important implications can be derived for the design and interpretation of experiments to characterize weak interactions, which are potentially important for brain processing.

The dicode workbench: A flexible framework for the integration of information and web services

Aiming to address requirements concerning integration of services in the context of ?big data?, this paper presents an innovative approach that (i) ensures a flexible, adaptable and scalable information and computation infrastructure, and (ii) exploits the competences of stakeholders and information workers to meaningfully confront information management issues such as information characterization, classification and interpretation, thus incorporating the underlying collective intelligence. Our approach pays much attention to the issues of usability and ease-of-use, not requiring any particular programming expertise from the end users. We report on a series of technical issues concerning the desired flexibility of the proposed integration framework and we provide related recommendations to developers of such solutions. Evaluation results are also discussed.

La ciudad editada: de Las Vegas a Nueva York (1972-1978): Venturi / Scott Brown / Koolhaas

Si hubiese un denominador común entre todas las artes en lo que ha venido llamándose postmodernidad, éste tendría mucho que ver con el final del origen de la obra. Desde la literatura y la música hasta las artes plásticas y la arquitectura, la superación de la modernidad ha estado caracterizada por la sustitución del concepto de creación por el de intervención artística, o lo que es lo mismo, la interpretación de lo que ya existe. A principios del siglo XX los conceptos modernos de creación y origen implicaban tener que desaprender y olvidar todo lo anterior con el ánimo de partir desde cero; incluso en un sentido material Mies sugería la construcción literal de la materia y su movimiento de acuerdo a unas leyes. A partir de la segunda mitad de siglo los planteamientos historicistas empezaron a surgir como reacción ante la amnesia y la supuesta originalidad de los modernos. En este contexto surgen los libros Learning from Las Vegas, 1972 y Delirious New York, 1978, ambos deudores en muchos aspectos con el anterior libro de Venturi, Complexity and Contradiction in Architecture, 1966. Estos dos libros sobre ciudades, alejándose decididamente de las tendencias historicistas de la época, proponían utilizar el análisis crítico de la realidad existente como vehículo para la teoría y el proyecto de manera simultánea, convirtiéndose indirectamente en Manifiestos. Si en un primer momento Venturi, Rossi y otros planteaban acabar con los límites formales establecidos por la modernidad, así como por cualquiera de los cánones anteriores, tomando la totalidad de la obra construida como sistema de referencia, - al igual que hiciera Eliot en literatura, - los libros de Las Vegas y Nueva York sugerían directamente borrar los límites de la propia disciplina, llegando a poner en duda ¿Qué puede ser considerado arquitectura? Sin embargo, debido precisamente a la ausencia total de límites y a la inmensidad del sistema referencial planteado, “todo puede ser arquitectura”, como apuntaba Hans Hollein en 1968, los libros proponen al mismo tiempo definir el campo de actuación de cada cual de manera individual. Los escritos sobre Las Vegas y Nueva York suponen por un lado la eliminación de los limites disciplinares y por otro, la delimitación de ámbitos de trabajo concretos para sus autores: los propios de cada una de las ciudades interpretadas. La primera parte de la Tesis, Lecciones, se ocupa del necesario proceso de aprendizaje y experimentación previo a la acción crítica propiamente dicha. Los arquitectos contemporáneos necesitan acumular material, conocimiento, documentación, experiencias... antes de lanzarse a proponer mediante la crítica y la edición; y al contrario que ocurría con los modernos, cuanto más abundante sea ese bagaje previo más rica será la interpretación. Las ciudades de Roma, Londres y Berlín se entienden por tanto como experiencias capaces de proporcionar a Venturi, Scott Brown y Koolhaas respectivamente, sus “personales diccionarios”, unas interminables imaginerías con las que posteriormente se enfrentarían a los análisis de Las Vegas y Nueva York. La segunda parte, Críticas, se centra en la producción teórica en sí: los dos libros de ciudades analizados en estrecha relación con el Complexity and Contradiction. El razonamiento analógico característico de estos libros ha servido de guía metodológica para la investigación, estableciéndose relaciones, no entre los propios escritos directamente, sino a través de trabajos pertenecientes a otras disciplinas. En primer lugar se plantea un importante paralelismo entre los métodos de análisis desarrollados en estos libros y los utilizados por la crítica literaria, observando que si el new criticism y el nuevo periodismo sirvieron de guía en los escritos de Venturi y Scott Brown, la nouvelle critique y su propuesta de identificación poética fueron el claro referente de Koolhaas al abordar Nueva York. Por otro lado, la relevancia ganada por la actividad de comisariado artístico y la aparición de la figura del curator, como autoridad capaz de utilizar la obra de arte por encima de las intenciones de su propio autor, sirve, al igual que la figura del editor, como reflejo de la acción transformadora y de apropiación llevada a cabo tanto en Learning from Las Vegas, como en Delirious New York. Por último y a lo largo de toda la investigación las figuras de Bergson y Baudelaire han servido como apoyo teórico. A través de la utilización que de sus ideas hicieron Venturi y Koolhaas respectivamente, se ha tratado de mostrar la proximidad de ambos planteamientos desde un punto de vista ideológico. La Inclusión propuesta por Venturi y la ironía utilizada por Koolhaas, la contradicción y la paradoja, no son sino el reflejo de lógicas que en ambos casos reaccionan al mismo tiempo contra idealismo y materialismo, contra modernidad y antimodernidad, en un continuo intento de ser lo uno y lo otro simultáneamente. ABSTRACT If there was a common denominator among all the arts in what has been called postmodernism, it would have much to do with the end of the origin of the artwork. From literature and music to fine arts and architecture, overcoming modernity has been characterized by replacing the concept of artistic creation by the one of intervention, in other words, the interpretation of what already exists. In the early twentieth century modern concepts of creation and origin involved unlearning and forgetting everything before with the firm intention of starting from scratch. Even in a material sense Mies suggested the literal construction of matter and its motion according to laws. From the mid-century historicist approaches began to emerge in response to the amnesia and originality alleged by moderns. In this context appeared the books Learning from Las Vegas, 1972 and Delirious New York, 1978, both debtors in many respects to the previous book by Venturi, Complexity and Contradiction in Architecture, 1966. These two books on cities, which broke away decidedly with the historicist trends of the time, proposed using critical analysis of the existing reality as a vehicle for theory and projecting at the same time, indirectly becoming manifests. If at first Venturi, Rossi and others pose to erase the formal limits set by modernity, as well as any of the canons before, taking the entire work built as a reference system, - as did Eliot in literature - the books on Las Vegas and New York proposed directly erasing the boundaries of the discipline itself, coming to question what could be considered architecture? However, and precisely because of the absence of limits and the immensity of the established framework, - “everything could be architecture” as Hans Hollein pointed in 1968, - the books suggested at the same time the definition of a field of action for each one individually. The cities of Las Vegas and New York represented on the one hand the elimination of disciplinary limits and on the other, the delimitation of specific areas of work to its authors: Those on each of the cities interpreted. The first part of the thesis, Lessons, attend to the necessary process of learning and experimentation before the critical action itself. Contemporary architects need to accumulate material, knowledge, information, experiences... before proposing through criticism and editing; and unlike happened with moderns, the most abundant this prior baggage is, the richest will be the interpretation. Rome, London and Berlin are therefore understood as experiences capable of providing Venturi, Scott Brown and Koolhaas respectively, their “personal dictionaries”, interminable imageries with which they would later face the analysis of Las Vegas and New York. The second part, Critiques, focuses on the theoretical production itself: the two books on both cities analyzed closely with the Complexity and Contradiction. The analogical reasoning characteristic of these books has served as a methodological guide for the research, establishing relationships, not directly between the writings themselves, but through works belonging to other disciplines. First, an important parallel is set between the methods of analysis developed in these books and those used by literary criticism, noting that if the new criticism and new journalism guided Venturi and Scott Brown´s writings, the nouvelle critique and its poetic identification were clear references for Koolhaas when addressing New York. On the other hand, the relevance gained by curating and the understanding of the figure of the curator as an authority capable to use artworks above the intentions of their authors, like the one of the Editor, reflects the appropriation and processing actions carried out both in Learning from Las Vegas, and Delirious New York. Finally and over all the research Bergson and Baudelaire figures resonate continuously. Through the use of their ideas done by Venturi and Koolhaas respectively, the research has tried to show the proximity of both approaches from an ideological point of view. Inclusion, as posed by Venturi and irony, as used by Koolhaas, contradiction and paradox are reflections of the logic that in both cases allow them to react simultaneously against idealism and materialism, against modernism and anti-modernism.

Affect and the Problem of Evil

A central aspect of the problem of evil or the argument from evil is the intensity or quantity of suffering. This quantity is conceived of as something objective and fixed. But because our experience is in part constituted and interpreted by our effectual orientation, there is no such objective quantum of suffering. But where there is no objective quantum of suffering, the argument from evil collapses. Here we begin by examining the connection between the philosophical and existential dimensions of the problem of and argument from evil as suffering. Next we consider the role of the affect in the constitution and interpretation of experience generally, together with implications for the argument from suffering. Third, we look at how a key affectual element of the argument from evil might undercut that argument. And finally, we consider a proposal to categorize suffering as a species of moral or spiritual failure, as affectually wrong.

República Federativa Evangélica: uma análise de gênero sobre a laicidade no Brasil a partir da atuação dos/as parlamentares evangélicos/as no Congresso Nacional no exercício da 54ª Legislatura São Bernardo do Campo

Essa pesquisa objetiva a análise da relação entre religião e política, em perspectiva de gênero considerando a atuação de parlamentares evangélicos/as na 54ª Legislatura (de 2011 a 2014) e a forma de intervenção desses atores no espaço político brasileiro quanto à promulgação de leis e ao desenvolvimento de políticas públicas que contemplem, dentre outras, a regulamentação do aborto, a criminalização da homofobia, a união estável entre pessoas do mesmo sexo e os desafios oriundos dessa posição para o Estado Brasileiro que se posiciona como laico. Ora, se laico remete à ideia de neutralidade estatal em matéria religiosa, legislar legitimado por determinados princípios fundamentados em doutrinas religiosas, pode sugerir a supressão da liberdade e da igualdade, o não reconhecimento da diversidade e da pluralidade e a ausência de limites entre os interesses públicos / coletivos e privados / particulares. Os procedimentos metodológicos para o desenvolvimento dessa pesquisa fundamentam-se na análise e interpretação bibliográfica visando estabelecer a relação entre religião e política, a conceituação, qualificação e tipificação do fenômeno da laicidade; levantamento documental; análise dos discursos de parlamentares evangélicos/as divulgados pela mídia, proferidos no plenário e adotados para embasar projetos de leis; pesquisa qualitativa com a realização de entrevistas e observações das posturas públicas adotadas pelos/as parlamentares integrantes da Frente Parlamentar Evangélica - FPE. Porquanto, os postulados das Ciências da Religião devidamente correlacionados com a interpretação do conjunto de dados obtidos no campo de pesquisa podem identificar o lugar do religioso na sociedade de forma interativa com as interfaces da laicidade visando aprofundar a compreensão sobre a democracia, sobre o lugar da religião nas sociedades contemporâneas e sobre os direitos difusos, coletivos e individuais das pessoas.

A “REVOLTA” DE JEÚ E A ESTELA DE DÃ: Um Estudo Em 2 Reis 10,28-36

A pesquisa tem por objetivo trabalhar o evento da Revolta de Jeú, em conjunto com a Estela de Dã, tendo como ponto de partida para tal, a exegese da perícope de 2 Reis 10-28,36. A história Deuteronomista apresenta o ato da Revolta de Jeú como sendo um feito demasiadamente importante, na restauração do culto a Javé em Israel, a partir de um contexto onde o culto a outras divindades, em Israel Norte, estava em pleno curso. No entanto, a partir da análise conjunta da Estela de Dã, que tem como provável autor o rei Hazael de Damasco, somos desafiados a ler esta história pelas entrelinhas não contempladas pelo texto, que apontam para uma participação ativa de Hazael, nos desfechos referentes a Revolta de Jeú, como sendo o responsável direto que proporcionou a subida de Jeú ao trono em Israel, clarificando desta forma este importante período na história Bíblica. Para tal análise, observar-se-á três distintos tópicos, ligados diretamente ao tema proposto: (1) A Revolta de Jeú e a Redação Deuteronomista, a partir do estudo exegético da perícope de 2 Reis 10,28-36, onde estão descritas informações pontuais sobre período em que Jeú reinou em Israel; (2) Jeú e a Estela de Dã, a partir da apresentação e análise do conteúdo da Estela de Dã, tratando diretamente dos desdobramentos da guerra em Ramote de Gileade, de onde se dá o ponto de partida à Revolta de Jeú; e por fim (3) O Império da Síria, onde a partir da continuidade da análise do conteúdo da Estela de Dã, demonstraremos a significância deste reino, além de apontamentos diretamente ligados ao reinado de Hazael, personagem mui relevante no evento da Revolta de Jeú.

Automated de novo sequencing of proteins by tandem high-resolution mass spectrometry

A de novo sequencing program for proteins is described that uses tandem MS data from electron capture dissociation and collisionally activated dissociation of electrosprayed protein ions. Computer automation is used to convert the fragment ion mass values derived from these spectra into the most probable protein sequence, without distinguishing Leu/Ile. Minimum human input is necessary for the data reduction and interpretation. No extra chemistry is necessary to distinguish N- and C-terminal fragments in the mass spectra, as this is determined from the electron capture dissociation data. With parts-per-million mass accuracy (now available by using higher field Fourier transform MS instruments), the complete sequences of ubiquitin (8.6 kDa) and melittin (2.8 kDa) were predicted correctly by the program. The data available also provided 91% of the cytochrome c (12.4 kDa) sequence (essentially complete except for the tandem MS-resistant region K13–V20 that contains the cyclic heme). Uncorrected mass values from a 6-T instrument still gave 86% of the sequence for ubiquitin, except for distinguishing Gln/Lys. Extensive sequencing of larger proteins should be possible by applying the algorithm to pieces of ≈10-kDa size, such as products of limited proteolysis.

The CONSORT statement: revised recommendations for improving the quality of reports of parallel group randomized trials

To comprehend the results of a randomized controlled trial (RCT), readers must understand its design, conduct, analysis and interpretation. That goal can only be achieved through complete transparency from authors. Despite several decades of educational efforts, the reporting of RCTs needs improvement. Investigators and editors developed the original CONSORT (Consolidated Standards of Reporting Trials) statement to help authors improve reporting by using a checklist and flow diagram. The revised CONSORT statement presented in this paper incorporates new evidence and addresses some criticisms of the original statement.

Contemplative Education CenterStage: Training the Mindful Performer

In the late 20th century and early 21st century, contemplative education/studies courses, concentrations, and initiatives have emerged in the academy. Although there has been significant discussion of postsecondary courses and programs that have integrated contemplative views and practices in the literature, there have been few studies of contemplative curricula and pedagogy in higher education. Additionally, there have been even fewer inquiries of the influence of contemplative education on performing arts training within conservatories and college and university departments. The aim of this qualitative study was two-fold: (1) to describe, interpret, and appraise the impact of contemplative education on the curricula of an interdisciplinary conservatory level performing arts program, MFA Contemporary Performance, at Naropa University; and (2) to disclose, compare, and analyze MFA student perceptions of the influence of contemplative education on their professional and personal development. The following questions guided this study: (1) How do faculty and students characterize contemplative education within the MFA in Theater: Contemporary Performance Program? (2) How does contemplative education impact the intended and operational curricula of courses within the MFA Contemporary Performance Program? (3) How do graduate students perceive the effects of contemplative education, offered by the MFA Contemporary Performance Program, on the development of their communication abilities, presence-in-performance, sociolinguistic perspectives, and aesthetic perspectives? Based on the research methodology of educational criticism and connoisseurship, this investigation provides a vivid description and interpretation of the intended and operational curricula of three core courses within the MFA program. These curricula were examined through five dimensions: intentional, curricular, pedagogical, structural, and evaluative. In order to shape our understanding of the contemplative and performative nature of the curricula, the significant and subtle qualities of the courses were further captured by preparation, context-building, reflective, showing, and closing conventions. Since the courses were grounded in postmodern view, they were evaluated according to Doll's criteria of richness, recursion, relations, and rigor for the evaluation of postmodern curricula. MFA first- and second-year students primarily characterized contemplative education as body/mind training for performance and personal development, sitting meditation, and cultivation of mindfulness and awareness. Student perceptions of the impact of contemplative education on the development of their communication abilities, presence-in-performance, sociolinguistic perspectives, and aesthetic perspectives, throughout the course of their two-year training, are presented in a dimensional analysis. The research reveals eight different themes that intersect the three core curricula and interviews with MFA students and faculty. These thematics include inclusivity, nowness, silence, improvisation, goodness, heart, training, and space. The beginning letter of each theme combines to form the acronym, insights. The framework of insights connects and illuminates the most potent aspects of MFA Contemporary Performance values and training.

Rotten Symbol Mongering: Scapegoating in Post-9/11 American War Literature

A rhetorical approach to the fiction of war offers an appropriate vehicle by which one may encounter and interrogate such literature and the cultural metanarratives that exist therein. My project is a critical analysis—one that relies heavily upon Kenneth Burke’s dramatistic method and his concepts of scapegoating, the comic corrective, and hierarchical psychosis—of three war novels published in 2012 (The Yellow Birds by Kevin Powers, FOBBIT by David Abrams, and Billy Lynn’s Long Halftime Walk by Ben Fountain). This analysis assumes a rhetorical screen in order to subvert and redirect the grand narratives the United States perpetuates in art form whenever it goes to war. Kenneth Burke’s concept of ad bellum purificandum (the purification of war) sought to bridge the gap between war experience and the discourse that it creates in both art and criticism. My work extends that project. I examine the symbolic incongruity of convenient symbols that migrate from war to war (“Geronimo” was used as code for Osama bin Laden’s death during the S.E.A.L team raid; “Indian Country” stands for any dangerous land in Iraq; hajji is this generation’s epithet for the enemy other). Such an examination can weaken our cultural “symbol mongering,” to borrow a phrase from Walker Percy. These three books, examined according to Burke’s methodology, exhibit a wide range of approaches to the soldier’s tale. Notably, however, whether they refigure the grand narratives of modern culture or recast the common redemptive war narrative into more complex representations, this examination shows how one can grasp, contend, and transcend the metanarrative of the typical, redemptive war story.
