A simplified approach for Chaplygin-type cosmologies

A new class of accelerating cosmological models driven by a one-parameter version of the general Chaplygin-type equation of state is proposed. The simplified version is naturally obtained from causality considerations with basis on the adiabatic sound speed vs plus the observed accelerating stage of the universe. We show that very stringent constraints on the unique free parameter a describing the simplified Chaplygin model can be obtained from a joint analysis involving the latest SNe type la data and the recent Sloan Digital Sky Survey measurement of baryon acoustic oscillations (BAO). In our analysis we have considered separately the SNe type la gold sample measured by [A.G. Riess et al.. Astrophys. J. 607 (2004) 665] and the supernova legacy survey (SNLS) from [P. Astier et al., Astron. Astrophys. 447 (2006) 31]. At 95.4% (c.l.), we find for BAO + gold sample, 0.91 <= alpha <= 1.0 and Omega(m) = 0.28(-0.048)(+0.043) while BAO + SNLS analysis provides 0.94 <= alpha <= 1.0 and Omega(m) = 0.27(-0.045)(+0.048).

Bacterial Community Composition in Brazilian Anthrosols and Adjacent Soils Characterized Using Culturing and Molecular Identification

Microbial community composition was examined in two soil types, Anthrosols and adjacent soils, sampled from three locations in the Brazilian Amazon. The Anthrosols, also known as Amazonian dark earths, are highly fertile soils that are a legacy of pre-Columbian settlement. Both Anthrosols and adjacent soils are derived from the same parent material and subject to the same environmental conditions, including rainfall and temperature; however, the Anthrosols contain high levels of charcoal-like black carbon from which they derive their dark color. The Anthrosols typically have higher cation exchange capacity, higher pH, and higher phosphorus and calcium contents. We used culture media prepared from soil extracts to isolate bacteria unique to the two soil types and then sequenced their 16S rRNA genes to determine their phylogenetic placement. Higher numbers of culturable bacteria, by over two orders of magnitude at the deepest sampling depths, were counted in the Anthrosols. Sequences of bacteria isolated on soil extract media yielded five possible new bacterial families. Also, a higher number of families in the bacteria were represented by isolates from the deeper soil depths in the Anthrosols. Higher bacterial populations and a greater diversity of isolates were found in all of the Anthrosols, to a depth of up to 1 m, compared to adjacent soils located within 50-500 m of their associated Anthrosols. Compared to standard culture media, soil extract media revealed diverse soil microbial populations adapted to the unique biochemistry and physiological ecology of these Anthrosols.

Understanding Foreign Masters : the examples of Rabindranath Tagore and Fyodor Dostoyevskiy

The Indian author Rabindranath Tagore was received like royalty during his visits to the West after winning the Nobel Prize in 1913. Dreams of foreign cultures offered a retreat from a complicated age. In a time when the West appeared to be living under threat of disintegration and when industrialism seemed like a cul-de-sac, he appeared to offer the promise of a return to a lost paradise, a spiritual abode that is superior to the restless Western culture. However, Tagore’s popularity faded rapidly, most notably in England, the main target of his criticism. Soon after Tagore had won the Nobel Prize, the English became indignant at Tagore’s anti-colonial attitude.Tagore visited Sweden in 1921 and 1926 and was given a warm reception. His visits to Sweden can be seen as an episode in a longer chain of events. It brought to life old conceptions of India as the abode of spirituality on earth. Nevertheless, interest in him was a relatively short-lived phenomenon in Sweden. Only a few of his admirers in Sweden appreciated the complexity of Tagore’s achievements. His “anathema of mammonism”, as a Swedish newspaper called it, was not properly received. After a steady stream of translations his popularity flagged towards the end of the 1920s and then almost disappeared entirely. Tagores visits in Sweden gave an indication that India was on the way to liberate itself from its colonial legacy, which consequently contributed to the waning of his popularity in the West. In the long run, his criticism of the drawbacks in the western world became too obvious to maintain permanent interest. The Russian author Fyodor Dostoyevskiy’s Crime and Punishment (1866) has enticed numerous interpretations such as the purely biographical approach. In the nervous main character of the novel, the young student Raskolnikov, one easily recognizes Dostoyevskiy himself. The novel can also be seen as a masterpiece of realistic fiction. It gives a broad picture of Saint Petersburg, a metropolis in decay. Crime and Punishment can also be seen as one of the first examples of a modern psychological novel, since it is focused on the inner drama of its main character, the young student Raskolnikov. His actions seem to be governed by mere coincidences, dreams and the spur of the moment. it seems fruitful to study the novel from a psychoanalytical approach. In his book Raskolnikov: the way of the divided towards unity in Crime and Punishment (1982), a Swedish scholar, Owe Wikström, has followed this line of interpretation all the way to Freud’s disciple C G Jung. In addition to this, the novel functions as an exciting crime story. To a large extent it is Viktor Sjklovskij and other Russian formalists from the 1920s and onwards who have taught the western audience to understand the specific nature of the crime story. The novel could be seen as a story about religious conversion. Like Lasarus in the Bible (whose story attracts a lot of attention in the novel) Raskolnikov is awakened from the dead, and together with Sonja he starts a completely new life. The theme of conversion has a special meaning for Dostoyevskiy. For him the conversion meant an acknowledgement of the specific nature of Russia itself. Crime and punishment mirrors the conflict between traditional Russian values and western influences that has been obvious in Russia throughout the history of the country. The novel reflects a dialogue that still continues in Russian society. The Russian literary historian Mikhail Bakhtin, who is probably the most famous interpreter of the works of Dostoyevskiy, has become famous precisely by emphasizing the importance of dialogues in novels like Crime and Punishment. According to Bakhtin, this novel is characterized by its multitude of voices. Various ideas are confronted with each other, and each one of them is personified by one of the characters in the novel. The author has resigned from his position as the superior monitor of the text, and he leaves it to the reader to decide what interpretation is the correct one..The aim of the present study is thus to analyze the complex reactions in the west to Tagore’s visits in Sweden and to Fyodor Dostoyevskiys novel Crime and Punishment.. This leads to more general conclusions on communication between cultures.

Mio i folksagan och karnevalen : En tolkning och narratologisk studie av Astrid Lindgrens verk Mio, min Mio

The purpose of the study is, based on a narratological perspective, to analyze and interpret the novel written by Astrid Lindgren: Mio, min Mio. It is based on the legacy of the folktale tradition, which is also the basis for carnival concept according to Bachtin. The study is based on a narrative model of Gérard Genette. Mio, min Mio is told as a first person narrator and can be interpreted as Bo tells it to himself. It is a frame story in which the outer story is the reality, while the inner story is the structure of the folktale where Mio embarks on a predetermined mission to fight against evil. Carnival concept involves a timed up-and-down-turn that is sanctioned and controlled, this fits well with this story seen from this interpretation. In the fantasy world everything has an idealized counterpart and Bo is, via Mio, in this world for a limited time. Children in our society are powerless, but are allowed to be mighty in children's literature. The story gets a subversive effect as it shows that adult standards are not absolute. Even if Bo turns back to his foster parents, he goes through this inner battle processing his thoughts and feelings. The love Bo will experience in imagination gives him the power to manage his real situation.

Men barnen då? : Ekonomiskt bistånd och det sociala arvet mellan föräldrar och barn

I denna kvalitativa studie har vi valt att undersöka hur man på enheten för ekonomiskt bistånd arbetar förebyggande för att motverka att det långvariga biståndstagandet går i socialt arv mellan föräldrar och barn. För att ta reda på detta har vi intervjuat socialsekreterare med erfarenhet och kompetens inom området. Det insamlade materialet har analyserats utifrån den sociala inlärningsteorin som ett försök till att förstå hur det sociala arvet kan föras vidare mellan generationer. Som ett komplement till teorin används även barnperspektivet i analysen då barnen har stor del i studien. Denna studie visar och bekräftar att långvarigt ekonomiskt biståndstagande kan komma att gå i socialt arv mellan föräldrar och barn. Studien visar även på vilket sätt förebyggande arbete för dessa familjer sker på enheten för ekonomiskt bistånd.

Prototype Generation from Ontology Charts

Semantic Analysis is a business analysis method designed to capture system requirements. While these requirements may be represented as text, the method also advocates the use of Ontology Charts to formally denote the system's required roles, relationships and forms of communication. Following model driven engineering techniques, Ontology Charts can be transformed to temporal Database schemas, class diagrams and component diagrams, which can then be used to produce software systems. A nice property of these transformations is that resulting system design models lend themselves to complicated extensions that do not require changes to the design models. For example, resulting databases can be extended with new types of data without the need to modify the database schema of the legacy system. Semantic Analysis is not widely used in software engineering, so there is a lack of experts in the field and no design patterns are available. This make it difficult for the analysts to pass organizational knowledge to the engineers. This study describes an implementation that is readily usable by engineers, which includes an automated technique that can produce a prototype from an Ontology Chart. The use of such tools should enable developers to make use of Semantic Analysis with minimal expertise of ontologies and MDA.

The Tastes of a Nation: M.F.K. Fisher and the Genre of Culinary Literature

This project works to situate this gastronomic revolution within a historical context, arguing at greater length that our contemporary food culture in the United States is in part the legacy of the body of food representations. Here we witness the evolution of a particular culinary sensibility that appealed to readers differently in different historical moments, as exhibited by the variety of ways that Fisher’s body of work was publicly received. By the end of the twentieth century, Fisher’s ethos reigned supreme, because Americans began to view food with less fear and anxiety as they slowly became more comfortable expressing their physical appetites and desires. By the millennium, Americans began to respect and honor the physical appetite and give more consideration to the quality and origin of the foods that they consumed. Feelings of guilt associated with the enjoyment of food began to diminish as well.

Model Configuration And Data Management In The Short-Term Water Information Forecasting Tools

The Short-term Water Information and Forecasting Tools (SWIFT) is a suite of tools for flood and short-term streamflow forecasting, consisting of a collection of hydrologic model components and utilities. Catchments are modeled using conceptual subareas and a node-link structure for channel routing. The tools comprise modules for calibration, model state updating, output error correction, ensemble runs and data assimilation. Given the combinatorial nature of the modelling experiments and the sub-daily time steps typically used for simulations, the volume of model configurations and time series data is substantial and its management is not trivial. SWIFT is currently used mostly for research purposes but has also been used operationally, with intersecting but significantly different requirements. Early versions of SWIFT used mostly ad-hoc text files handled via Fortran code, with limited use of netCDF for time series data. The configuration and data handling modules have since been redesigned. The model configuration now follows a design where the data model is decoupled from the on-disk persistence mechanism. For research purposes the preferred on-disk format is JSON, to leverage numerous software libraries in a variety of languages, while retaining the legacy option of custom tab-separated text formats when it is a preferred access arrangement for the researcher. By decoupling data model and data persistence, it is much easier to interchangeably use for instance relational databases to provide stricter provenance and audit trail capabilities in an operational flood forecasting context. For the time series data, given the volume and required throughput, text based formats are usually inadequate. A schema derived from CF conventions has been designed to efficiently handle time series for SWIFT.

Reflexões sobre o turismo cultural na "Cidade Maravilhosa"

A Organização Mundial do Turismo - OMT (2003) afirma que está surgindo uma nova etapa de turismo. No mundo pós-moderno, o movimento turístico tem procurado cada vez mais pelo "diferente", pelo "outro", surgindo, assim, uma motivação para o "turismo com base no legado cultural" (BARRETTO, 2000). Aliando-se ao exposto, o Ministério do Turismo criou, em 2006, uma tipologia do turismo, baseada nas motivações para a realização das viagens, ou na segmentação do mercado. O projeto, que objetiva "organizar o turismo para fins de planejamento, gestão e mercado" divide o turismo em cinco segmentos prioritários, sendo um deles o "cultural". Desta forma, a presente dissertação se propõe a realizar algumas reflexões acerca do turismo cultural no município do Rio de Janeiro - cidade que possui um papel central na história da vida política e cultural brasileira. Realizou-se primeiramente um levantamento dos diversos conceitos que se imbricam com o turismo cultural - cultura, patrimônio cultural, memória, autenticidade, identidades e consumo - para, de maneira ampla, discutir sobre a temática. Através de uma pesquisa de campo, buscou-se delinear a oferta turística, averiguando como o turismo cultural é atualmente trabalhado pelas principais operadoras turísticas da área, no intento de discutir o tema de forma crítica e dialética. A análise desse material possibilitou-nos uma visão crítica das práticas acerca do turismo cultural na "Cidade Maravilhosa", nos permitindo refletir de maneira mais contundente sobre o desenvolvimento eficaz da atividade turística na cidade do Rio de Janeiro.

De olho na eternidade: a construção do arquivo privado de Antonio Carlos Jobim

O arquivo de Antonio Carlos Jobim, assim como todo arquivo pessoal, foi colecionado e mantido para satisfazer o desejo de um homem que sempre se preocupou com sua imagem. Este trabalho demonstra a história da construção e organização desse acervo, além de fortalecer a hipótese de que o arquivo, em sua integridade, configura-se como uma escrita autobiográfica. Abordo a organização arquivística do fundo Antonio Carlos Jobim, dentro do Instituto que leva seu nome, e dou ênfase na subsérie Cadernos de anotações, da série Produção Intelectual do Titular. Esses cadernos são um tipo de documento singular, quer pelo uso que deles fazia o maestro, quer pela sua prática memorial. O estudo destas fontes primárias nos permite inferir a imagem construída pelo próprio titular, e também evidencia o plano dos guardiões dessa memória em perpetuá-la: Jobim decidiu manter um arquivo pessoal com o claro propósito de preservar sua obra e projetá-la para o futuro. Esse cuidado foi transmitido para seus herdeiros, que além das obras musicais, cuidam, hoje, de seu legado arquivístico dentro do Instituto Antonio Carlos Jobim.

O problema da liberdade no primeiro livro dos discorsi de Maquiavel

A pesquisa pretende analisar e contextualizar o problema da liberdade cívica no Primeiro Livro dos Discorsi de Maquiavel. A análise será histórico-político-filosófica do ideário da liberdade, construída pelos humanistas cívicos florentinos, entre os séculos XIV e XV, e criticado e realizado teoricamente por Maquiavel pelo viés do republicanismo. O que está em questão é a herança do conceito de libertà e sua confluência contemporâmea na obra do pensador florentino.

Ruptura e Legado: o colapso da cordialidade oficial entre o Brasil e a Argentina

Este trabalho busca identificar os fatores que concorrem para explicar a mudança no eixo entre a Argentina e o Brasil, no começo da década de 1980, quando as duas diplomacias convergiram em um projeto de integração inovador. O argumento apresentado defende que a aproximação entre os dois países foi o legado, inesperado, do relacionamento bilateral ao longo da gestão do Presidente Geisel (1974-1979).

Integração de políticas sociais: um estudo de caso sobre o Bolsa Família

O presente trabalho propõe-se a analisar o processo de integração das diversas ações de transferência de renda no âmbito do governo federal, durante a primeira gestão do presidente Luiz Inácio Lula da Silva, entre os anos de 2003 e 2006, que resultou na criação do Programa Bolsa Família. A análise proposta busca contribuir para ampliar o conhecimento sobre o governo e a administração pública, gerando informações sobre a formação da agenda governamental de um governo comprometido, programaticamente, com a redução da pobreza e da desigualdade social. Quanto ao caminho metodológico percorrido, na elaboração desta dissertação, partiu-se da seguinte pergunta-chave: por que e como se deu o processo de integração do Programa Bolsa Família? A metodologia de pesquisa aplicada consistiu na identificação das razões para a entrada deste tema na agenda governamental do primeiro governo do presidente Lula. Para tanto, foi realizado um estudo de caso, objetivando identificar quais atores participaram da discussão sobre a unificação dos programas de transferência de renda e quais foram os conceitos que os orientaram. Como instrumento de pesquisa, optou-se pela aplicação de entrevistas semi-estruturadas com alguns participantes do Grupo de Trabalho de Unificação dos Programas de Transferência de Renda. Além das entrevistas, as outras fontes utilizadas foram: os relatórios e/ou atas das reuniões do Grupo de Trabalho, da Câmara de Política Social do governo; as legislações dos programas anteriores; a legislação do Programa Bolsa Família; os discursos realizados pelo presidente eleito Luiz Inácio Lula da Silva entre janeiro e outubro de 2003. Por meio da análise, de toda a documentação elencada, é possível verificar o esforço governamental no sentido de implementar mudanças nos programas de transferência de renda. Dessas reuniões foram produzidos relatórios pelos Grupos Técnicos, abordando as políticas sociais para a redução das desigualdades, construindo o Programa Bolsa Família levando se em conta a importância do legado histórico das ações existentes. Como resultado da pesquisa, identificou-se que o presidente Lula, a Câmara de Política Social e o seu grupo de especialistas técnicos souberam aproveitar a janela de oportunidades de um governo que estava iniciando com forte apelo para desenvolver políticas públicas de combate à fome e a pobreza. Após percorrer o caminho de reconstrução histórica para a elaboração dessa dissertação, buscou-se destacar algumas contribuições que tem por objetivo servir de incentivo para novos estudos sobre o processo decisório na esfera pública de governo.
