Lithostatigraphy of the CESAR cores

Sixteen piston cores and twelve gravity cores were successfully recovered from northern and southern crests of the eastern Alpha Ridge andfrom the Alpha Ridge graben. All but one core contain late Cenozoic muds with variable amounts of sand- to pebble-sized clastic material that probably reflects transport by ice during the past 4-5 Ma. Sixteen Cenozoic-Holocene lithostratigraphic units have been delimited on the basis of sediment texture, structure, colour, detrital carbonate and authigenicferromanganese content. The composition of the upper 13 units in the CESAR cores is similar to the Fletcher's Ice Island cores; hence most units can be broadly correlated over most of the Central Arctic Ocean. Three new lithostratigraphic units (A1-A3) occur at the base of CESAR cores from the northern Alpha Ridge crest. Paleomagnetic and palynological data indicate a Late Miocene-Early Pliocene age for unit A3, which confirms previous reports of a slow sedimentation rate during the Cenozoic. CESAR core 6 was obtained from an erosional surface on top of a fault block at the north edge of the Alpha Ridge graben. This core contains ca. 2m of laminated diatom ooze of Campanian-Maastrichtian age and two ?Paleogene volcanic ash units below a brown mud unit which probably corresponds to units A2 and A3. The biosiliceous ooze contains no foraminifera or silicoflagellates and only few dinoflagellates. There is little difference in biogenic or clastic sediment content between light and dark laminae and the rhythmites do not appear to be annual varves produced in an upwelling environment. The microstructure and fluctuating mineral composition of the laminae most closely resemble those of lami- nated chert beds in the Triassic forearc basins of Japan.

A Flor da Melancolia e o Ímpeto Cesariano (ou a Negação e a Afirmação da Vida) nas Memórias Póstumas de Brás Cubas de Machado de Assis

Esta dissertação tem por objecto a flor da melancolia e o ímpeto cesariano nas Memórias Póstumas de Brás Cubas, de Machado de Assis, noções que reflectem um confronto com a temática schopenhauriana e nietzschiana da negação e afirmação da vida. Trata-se de uma tese em Filosofia – variante Estética, que procura identificar no romance do escritor brasileiro aquilo que nele corresponde a um substrato metafísico, a uma procura pelo sentido e a uma tentativa de lidar com o sofrimento – feitas por um homem para quem Deus morreu, e que encontra numa dimensão temporal tudo o que há para encontrar. Consideramos que a despeito do pessimismo que atravessa o livro, há nele uma vitalidade que decorre grandemente do ponto de vista do narrador, do facto de as Memórias serem Póstumas. E pensamos que é no acto criador da escrita que Brás Cubas, e com ele Machado de Assis, firma o estandarte de César e abotoa a flor da melancolia, o sofrimento de que padece a Humanidade e que, no caso do personagem, surge depois da morte da mãe, no período de luto em que, pela primeira vez, há um questionamento acerca de si próprio e do seu lugar no mundo.

An apprehensive aesthetic : the legacy of modernist culture

Art continues to bemuse and confuse many people today. Yet, its critical analyses are saturated with daunting analyses of contemporary art's exhaustion, its predictability or its absorption into global commercial culture. In this book, the author seeks to clarify this apprehensive perception of art. He argues it is a consequence not only of confounding art-works, but also of the paradoxical impetus of a culture of modernity. By positively reassessing the perplexing or apprehensive features of cultural modernity as well as of aesthetic inquiry, this book redefines the ambitions of art in the wake of this legacy. In the process, it challenges many familiar approaches to art inquiry in order to offer a new understanding of the aesthetic, social and cultural aspirations of art in our time.

GABRIEL URBAIN FAURÉ, THE UNSUNG MODERNIST: A PERFORMANCE SURVEY OF SELECTED LATE WORKS WRITTEN AFTER 1892 FOR PIANO SOLO, AND PIANO IN COLLABORATION WITH VIOLIN, VIOLONCELLO, AND VOICE

Gabriel Urbain Fauré lived during one of the most exciting times in music history. Spanning a life of 79 years (1845-1924), he lived through the height of Romanticism and the experimental avant-garde techniques of the early 20th century. In Fauré's music, one can find traces of Chopin, Liszt, Mendelssohn, Debussy and Poulenc. One can even argue that Fauré presages Skryabin and Shostakovich. The late works of Gabriel Fauré, chiefly those composed after 1892, testify to the argument that Fauré holds an important position in the shift from tonal to atonal composition and should be counted among such transitional composers as Gustav Mahler, Claude Debussy, Erik Satie, Richard Strauss, and Ferruccio Busoni. Fauré's unique way of fashioning harmonic impetus of almost purely linear means, resulting in a synthesis of harmonic and melodic devices, led me to craft the term mélodoharmonique. This term refers to a contrapuntally motivated technique of composition, particularly in a secondary layer of musical texture, in which a component of harmonic progression (i.e. arpeggiation, broken chord, etc.) is fused with linear motivic or thematic development. This dissertation seeks to bring to public attention through exploration in lecture and recital format, certain works of Gabriel Fauré, written after 1892. The repertoire will be selected from works for solo piano and piano in collaboration with violin, violoncello, and voice, which support the notion of Fauré as a modernist deserving larger recognition for his influence in the transition to atonal music. The recital repertoire includes the following--Song Cycles: La bonne chanson, opus 61; La chanson d'Ève, opus 95; Le jardin clos, opus 106; Mirages, opus 113; L'horizon chimérique, opus 118; Piano Works: Prelude in G minor opus 103, No. 3; Prelude in E minor opus 103, No. 9; Eleventh Nocturne, opus 104, No.1; Thirteenth Nocturne, opus 119; Chamber Works: Second Violin Sonata, opus 108; First Violoncello Sonata, opus 109; Second Violoncello Sonata, opus 117.

Action research of cyclonic transactions in online management education

The aim of the research was to generate a cyclonic model for understanding the influences and processes of continuously improving management education in an environment rich in online learning technologies. The research questions were:
1. What is the nature of the cyclonic interactions observed in the transactions of a team of online management educators?
2. How might an understanding of cyclonic interactions
a. help refine action research, and
b. generate rich insight for online management education?
The methodology was an action research project. The research team worked in an online Master of Business Administration (MBA) to continuously develop teaching practice in one unit of the MBA. The methodology matched the objectives of the project, and the appropriate rigour associated with qualitative, interpretive research. The results showed that theories of systems and relational dynamics, adapted to hermeneutics and aligned with other learning theories, can be framed by the metaphor of a cyclone to conduct research into teaching practice and build upon the theory base in the field of online education.
Online management education is subject to reinterpretations. The cyclonic framework explains some of the changes. The project showed that a chaotic but organised cyclonic program development process in one particular MBA course was informative for and informed by the chaotic and cyclonic globalized business world. For the education of managers the cyclonic view was relevant. The approach was metaphorical and, therefore, opened new ways of seeing and speaking. Findings pertained to the nature of the cyclonic interactions, how an understanding of cyclonic interactions helped to refine action research, and how an understanding of cyclonic interactions helped generate rich insight for online management education.
It was found that it was the asymmetrical impetus of imperfection that created the examples of cyclonic learning spirals formed as double feedback loops for improved understanding. Online education in the action research required cyclical enhancement of connectedness by teachers, stronger emphasis on relational considerations in learning, and heightened expectations of collaboration by educators. It became possible to correlate earlier conceptions of action research with cyclonic categories and analyse the parallels with events in this action research project. Models were developed and presented to explain 3 cyclonic connections with hermeneutics, collaborative teaching, online resource
development, and the environment of online management.

Evaluation of the meeting on promoting energy effeiciency in the Caribbean

The Economic Commission for Latin America and the Caribbean (ECLAC), in collaboration with the Caribbean Development Bank, convened the meeting “Promoting Energy Efficiency in the Caribbean” on 13–14 May 2010 at its Subregional Headquarters for the Caribbean, in Port of Spain, Trinidad and Tobago. The meeting had its genesis in the convening of consultations in 2009 with Latin American and Caribbean countries, members of the Latin American Energy Agency, and resulted in a report calling for greater awareness of energy efficiency among Caribbean countries, so as to provide the impetus of the development of a regional energy efficiency strategy. An evaluation form was distributed towards the end of the meeting, providing the participants with the opportunity to assess the quality and success of different aspects of the meeting (the logistics of the meeting, venue, the organization and the technical aspects of the meeting). ECLAC has acknowledged the importance of receiving feedback from its meeting participants to tailor future meetings to the specific needs of its clients.

Understanding the role of Dimethylsulfoniopropionate as a potential chemotactic cue for coral-associated bacteria

Most reef-building corals are known to engage in non-pathogenic symbiosis not only with unicellular dinoflagellates from the genus Symbiodinium, but also with other microscopic organisms such as bacteria, fungi, and viruses. The functional details of these highly complex associations remain largely unclear. The impetus of this study is to gain a better understanding of the symbiotic interaction between marine bacteria and their coral host. Studies have shown that certain bacterial orders associate with specific certain coral species, thus making the symbiotic synergy a non-random consortium. Consequently both corals and bacteria may be capable of emitting chemical cues that enable both parties to find one another and thus generate the symbiosis. The production of these cues by the symbionts may be the result of environmental stimuli such as elevated ocean temperatures, increased water acidity, and even predation. One potential chemical cue could be the compound DMSP (Dimethylsulfoniopropionate) and its sulphur derivatives. Reef-building corals are believed to be the major producers of the DMSP during times of stress. Marine bacteria utilize DMSP as a source of sulfur and carbon. As a result corals could potentially attract their bacterial consortium depending on their DMSP production. This would enable them to adapt to fluctuating environmental conditions by changing their bacterial communities to that which may aid in survival. To test the hypothesis that coral-produced DMSP plays a role in attracting symbiotic bacteria, this study utilized the advent of high-throughput sequencing paired with chemotactic assays to determine the response of coral-associated bacterial isolates towards the DMSP compound at differing concentrations. Chemotaxis assays revealed that some isolates responded positively towards the DMSP compound. This finding adds to existing evidence suggesting that coral-associated pathogens utilize chemotaxis as a host colonization and detection mechanism. Thus the symbiotic bacteria that make up the coral microbiome may also employ this process. Furthermore this study demonstrates that bacterial motility may be a strong contributing factor in the response to the chemotactic cue. Swarming motility may be better suited for bacteria that need to respond to a chemical gradient on the surface of the coral. Therefore the isolates that were able to swarm seemed to respond more strongly to the DMSP.

Understanding the role of Dimethylsulfoniopropionate as a Potential Chemotactic Cue for Coral-Associated Bacteria

Most reef-building corals are known to engage in symbiosis not only with unicellular dinoflagellates from the genus, Symbiodinium, but they also sustain highly complex symbiotic associations with other microscopic organisms such as bacteria, fungi, and viruses. The details of these non-pathogenic interactions remain largely unclear. The impetus of this study is to gain a better understanding of the symbiotic interaction between marine bacteria and a variety of coral species representative of differing morphologies. Studies have shown that certain bacterial orders associate specifically with certain coral species, thus making the symbiotic synergy a non-random consortium. Consequently both corals and bacteria may be capable of emitting chemical cues that enables both parties to find one another and thus creating the symbiosis. One potential chemical cue could be the compound DMSP (Dimethylsulfoniopropionate) and its sulphur derivatives. Reef-building corals are believed to be the major producers of the DMSP and its derivatives during times of stress. As a result corals could potentially attract their bacterial consortium depending on their DMSP production. Corals may be able to adapt to fluctuating environmental conditions by changing their bacterial communities to that which may aid in survival. The cause of this attraction may stem from the capability of a variety of marine bacteria to catabolize DMSP into different metabolically significant pathways, which may be necessary for the survival of these mutualistic interactions. To test the hypothesis that coral-produced DMSP play a role in attracting symbiotic bacteria, this study utilized the advent of high-through sequencing paired with bacterial isolation techniques to properly characterize the microbial community in the stony coral Porites astreoides. We conducted DMSP swarming and chemotaxis assays to determine the response of these coral-associated bacterial isolates towards the DMSP compound at differing concentrations. Preliminary data from this study suggests that six out of the ten bacterial isolates are capable of conducting unidirectional motility; these six isolates are also capable of conducting swarming motility in the direction of an increasing DMSP concentration gradient. This would indicate that there is a form of positive chemotaxis on behalf of the bacteria towards the DMSP compound. By obtaining a better understanding of the dynamics that drive the associations between bacterial communities and corals, we can further aid in the protection and conservation processes for corals. Also this study would further elucidate the significance of the DMSP compound in the survival of corals under times of stress.

Impacto solvencia II en un seguro de vida

La actividad aseguradora supone la transferencia de riesgos del asegurado al asegurador. El asegurador se compromete al pago de una prestación si el riesgo se realiza. Se produce un cambio en el ciclo productivo. El asegurador vende una cobertura sin conocer el momento y el coste exacto de dicha cobertura. Esta particularidad de la actividad aseguradora explica la necesidad para una entidad aseguradora de ser solvente en cada momento y ante cualquier imprevisto. Por ello, la solvencia de las entidades aseguradoras es un aspecto que se ha ido recogiendo en las distintas normativas que han regulado la actividad aseguradora y al que se ha ido dando cada vez más importancia. Actualmente la legislación vigente en materia de solvencia de las aseguradoras esta regulada por la directiva europea Solvencia I. Esta directiva establece dos conceptos para garantizar la solvencia: las provisiones técnicas y el margen de solvencia. Las provisiones técnicas son las calculadas para garantizar la solvencia estática de la compañía, es decir aquella que hace frente, en un instante temporal determinado, a los compromisos asumidos por la entidad. El margen de solvencia se destina a cubrir la solvencia dinámica, aquella que hace referencia a eventos futuros que puedan afectar la capacidad del asegurador. Sin embargo en una corriente de gestión global del riesgo en la que el sector bancario ya se había adelantado al sector asegurador con la normativa Basilea II, se decidió iniciar un proyecto europeo de reforma de Solvencia I y en noviembre del 2009 se adoptó la directiva 2009/138/CE del parlamento europeo y del consejo, sobre el seguro de vida, el acceso a la actividad de seguro y de reaseguro y su ejercicio mas conocida como Solvencia II. Esta directiva supone un profundo cambio en las reglas actuales de solvencia para las entidades aseguradoras. Este cambio persigue el objetivo de establecer un marco regulador común a nivel europeo que sea más adaptado al perfil de riesgo de cada entidad aseguradora. Esta nueva directiva define dos niveles distintos de capital: el SCR (requerimiento estándar de capital de solvencia) y el MCR (requerimiento mínimo de capital). Para el calculo del SCR se ha establecido que el asegurador tendrá la libertad de elegir entre dos modelos. Un modelo estándar propuesto por la Autoridad Europea de Seguros y Pensiones de Jubilación (EIOPA por sus siglas en inglés), que permitirá un calculo simple, y un modelo interno desarrollado por la propia entidad que deberá ser aprobado por las autoridades competentes. También se contempla la posibilidad de utilizar un modelo mixto que combine ambos, el estándar y el interno. Para el desarrollo del modelo estándar se han realizado una serie de estudios de impacto cuantitativos (QIS). El último estudio (QIS 5) ha sido el que ha planteado de forma más precisa el cálculo del SCR. Plantea unos shocks que se deberán de aplicar al balance de la entidad con el objetivo de estresarlo, y en base a los resultados obtenidos constituir el SCR. El objetivo de este trabajo es realizar una síntesis de las especificaciones técnicas del QIS5 para los seguros de vida y realizar una aplicación práctica para un seguro de vida mixto puro. En la aplicación práctica se determinarán los flujos de caja asociados a este producto para calcular su mejor estimación (Best estimate). Posteriormente se determinará el SCR aplicando los shocks para los riesgos de mortalidad, rescates y gastos. Por último, calcularemos el margen de riesgo asociado al SCR. Terminaremos el presente TFG con unas conclusiones, la bibliografía empleada así como un anexo con las tablas empleadas.

L'image entre réflexion et représentation. Aby Warburg et Walter Benjamin

Pour la pensée humaine, l’image a toujours constitué une interrogation laissée sans réponse définitive : de l’interdit biblique à la possibilité technologique infinie, l’image a traversé des étapes conceptuelles complexes et hétérogènes. Aujourd’hui, on conçoit l’image comme une présence incontournable de l’existence quotidienne et comme une forme de réflexion mystérieuse. Cette thèse propose une analyse de la vision sur l’image chez Walter Benjamin et Aby Warburg à travers quelques concepts essentiels : image de pensée, survivance, espace de pensée, coupure, représentation de l’histoire. Située énigmatiquement entre les arts visuels et la pensée philosophique, l’image devient un sujet de réflexion à la fin du 19e siècle et au début du 20e siècle; les deux penseurs mentionnés ont été les premiers à interroger les valeurs conceptuelles de l’image et à chercher de l’évoquer en tant que spectre de la pensée. Les morceaux aphoristiques et les articles critiques de Benjamin rencontrent discrètement les études esthétiques de Warburg au point où l’idée de l’image amorce toute réflexion. Pour l’imaginaire contemporain, les structures conceptuelles bâties par Benjamin et Warburg constituent des éléments dominants dans l’engrenage réflexif atonal d’aujourd’hui. Lorsque le Denkraum (espace de pensée) et le Denkbild (image de pensée) gèrent la dynamique de la philosophie de Benjamin et Warburg, le Nachleben (survie) et la coupure nuancent le grand tableau de l’histoire (Geschichtsdarstellung). L’analyse comparatiste de ces concepts aboutit à la conclusion que l’image est intimement et paradoxalement liée à la vision de l’histoire; en fait, l’image n’est qu’une représentation de l’histoire qui, à son tour, se représente dans chaque image.

Densification & affordability : comparative real estate projects across Montreal

Montréal, Québec se construit vers une forme urbaine compacte, mais il en relève des questionnements quant aux effets sur l’abordabilité et l’accession à la propriété. En tenant compte du processus de la densification urbaine, une enquête sur une série de projets de condominiums immobiliers à travers la ville est menée afin de divulguer les prix des projets nouveaux ou en construction. Au préalable, ceci survole la littérature et les études actuelles portant sur la planification urbaine, notamment celles qui sont reliées au Smart Growth, études dans lesquelles le contexte de densification et de tendances consuméristes à préférer les formes urbaines étalées est mis en évidence. Essentiellement, Moroni (2010) souligne l’approche dichotomique en planification urbaine entre les perspectives «teleocratic» et «nomocratic». La densification montréalaise actuelle contemporaine s’exprime par une multitude de modèles de condos conformes aux nouvelles tendances démographiques et des modes de vie. En s’appuyant sur les critères du programme Accès Condos, sur les critères du SCHL (32% du revenu) et sur le revenu médian des ménages, le niveau d’accessibilité à la propriété d’un condominium peut être mesuré. Les résultats indiquent que selon ces critères, les logements de style condominium, neufs et en construction, sont abordables. L’analyse contribue empiriquement à la littérature en exposant les liens entre les stratégies actuelles de densification urbaine avec l’abordabilité des logements condos. La recherche porte un regard nouveau sur le phénomène condo à Montréal et ses tendances démographiques. La ville est divisée selon le modèle Burgess et la recherche mène un sondage comparatif des prix pour déterminer l’abordabilité. Les résultats suggèrent que les projets condos actuels sont relativement abordables pour les ménages avec un revenu médian et plus, selon Accès Condos.

Industria de calzado jovical una lección empresarial de perdurabilidad

Esta investigación acerca de lecciones empresariales de perdurabilidad se basa en el caso de Industria de Calzado Jovical, reconocida empresa del sector de la industria del cuero y calzado en Colombia. A lo largo del documento se tienen en cuenta tres momentos en la historia de esta compañía: Antes, durante y después de las crisis de los años 90 resultado de la difícil situación económica que vivía el país ocasionada por la contracción de la demanda. Esta investigación tiene como objetivo principal identificar las causas que llevaron a la crisis a Industria de Calzado Jovical y además aprender cómo esta organización logró alcanzar la ruta de la perdurabilidad después de sobrepasar esta crisis. Este trabajo, se desarrolló con la colaboración del Sr. Cesar Jaramillo Gerente General de Industria de Calzado Jovical, quien nos brindó su ayuda para el trabajo de campo permitiendo tener una mejor visión y entender el problema en su totalidad. Se plantea un proceso de observación y posterior análisis con el fin de entender cómo fue que la empresa entró en estado de crisis y también como logró mitigarlo, convirtiéndose en una empresa perdurable hasta la actualidad. Teniendo en cuenta las situaciones que condujeron a la empresa a la crisis y su comportamiento a nivel interno, externo y del mercado. Además se realiza un acercamiento a la gestión de sus líderes y las estrategias utilizadas por estos, basadas en testimonios y experiencias. Para efectos de este documento se propone seguir el lineamiento planteado por la Universidad del Rosario en el que se divide la gestión administrativa de una empresa en Dirección y Gerencia, los cuales serán los argumentos centrales de esta investigación con el fin de explicar los motivos del fracaso que están asociados a cada uno de los componentes esenciales de la gestión administrativa, y es en este punto donde se buscan las fallas para lograr visualizar las estrategias implantadas por la compañía Industria de Calzado Jovical para conseguir ese resurgir en la industria de calzado.
