Water vapour foreign-continuum absorption in near-infrared windows from laboratory measurements

For a long time, it has been believed that atmospheric absorption of radiation within wavelength regions of relatively high infrared transmittance (so-called ‘windows’) was dominated by the water vapour self-continuum, that is, spectrally smooth absorption caused by H2O−H2O pair interaction. Absorption due to the foreign continuum (i.e. caused mostly by H2O−N2 bimolecular absorption in the Earth's atmosphere) was considered to be negligible in the windows. We report new retrievals of the water vapour foreign continuum from high-resolution laboratory measurements at temperatures between 350 and 430 K in four near-infrared windows between 1.1 and 5 μm (9000–2000 cm−1). Our results indicate that the foreign continuum in these windows has a very weak temperature dependence and is typically between one and two orders of magnitude stronger than that given in representations of the continuum currently used in many climate and weather prediction models. This indicates that absorption owing to the foreign continuum may be comparable to the self-continuum under atmospheric conditions in the investigated windows. The calculated global-average clear-sky atmospheric absorption of solar radiation is increased by approximately 0.46 W m−2 (or 0.6% of the total clear-sky absorption) by using these new measurements when compared with calculations applying the widely used MTCKD (Mlawer–Tobin–Clough–Kneizys–Davies) foreign-continuum model.

Phylogenetic variation in the shoot mineral concentration of angiosperms

The calcium (Ca) concentration of plant shoot tissues varies systematically between angiosperm orders. The phylogenetic variation in the shoot concentration of other mineral nutrients has not yet been described at an ordinal level. The aims of this study were (1) to quantify the shoot mineral concentration of different angiosperm orders, (2) to partition the phylogenetic variation in shoot mineral concentration between and within orders, (3) to determine if the shoot concentration of different minerals are correlated across angiosperm species, and (4) to compare experimental data with published ecological survey data on 81 species sampled from their natural habitats. Species, selected pro rata from different angiosperm orders, were grown in a hydroponic system under a constant external nutrient regime. Shoots of 117 species were sampled during vegetative growth. Significant variation in shoot carbon (C), calcium (Ca), potassium (K), and magnesium (Mg) concentration occurred between angiosperm orders. There was no evidence for systematic differences in shoot phosphorus (P) or organic-nitrogen (N) concentration between orders. At a species level, there were strong positive correlations between shoot Ca and Mg concentration, between shoot P and organic-N concentration, and between shoot K concentration and shoot fresh weight:dry weight ratio. Shoot C and cation concentration correlated negatively at a species level. Species within the Poales and the Caryophyllales had distinct shoot mineralogies in both the designed experiment and in the ecological survey.

Biała Góra: the forgotten colony in the Medieval Pomeranian-Prussian borderlands

Biała Góra 3 is a small settlement founded in the late twelfth or early thirteenth century AD in the disputed Christian borderlands of Northern Europe. The incorporation of Pomerania into the Polish state in the tenth century was followed by a process of colonisation across the lower Vistula valley, which then stalled before resuming in the thirteenth century under the Teutonic Order. Biała Góra 3 is unusual in falling between the two expansionist phases and provides detailed insight into the ethnicity and economy of this borderland community. Pottery and metalwork show strong links with both Pomeranian and German colonists, and caches of bricks and roof tiles indicate durable buildings of the kind associated with the monastic and military orders. Evidence for the presence of merchants suggests Biała Góra 3 was one of many outposts in the commercial network that shadowed the Crusades.

Judah Benjamin: marginalized outsider or admitted insider?

Judah Benjamin (1811-1884) was one of the greatest of nineteenth century lawyers. This article analyses how a young man who might have been marginalized in society because of the circumstances of his birth, ethnic origin and religious identity rose to prominence in law, politics and business in the United Kingdom and the United States.

Caribbean Irish connections

There has been an Irish presence within the Caribbean since at least the 1620s and yet the historical and cultural dimensions of this encounter remain relatively under-researched and are often conceived of in reductive terms by crude markers such as redlegs or poor whites. While there are some striking reminders of this hitory throughout the region, this collection explores how the complications and contradictions of Irish Caribbean relations are much richer and deeper than previously recognized. Caribbean Irish Connections makes an important contribution to Irish studies by challenging the dominance of a US diasporic history and a disciplinary focus on cultural continuity and ancestry. Likewise, within Caribbean studies, the Irish presence troubles the orthodox historical models for understanding race and the plantation, race and class structures, as well as questions of ethnic and religious minorities. The contributors emphasize the importance of understanding the transatlantic nexus between Ireland and the Caribbean in terms of the shared historical experiences of dislocation, diaspora and colonization, as well as of direct encounter. This collection pays tribute to the extraordinarily rich tradition of cultural expression that informs both cultures and their imagination of each other.

L’illustration marginale d’un ouvrage profane : étude du manuscrit Paris, Bibliothèque nationale de France, français 95, xiiie siècle (1290)

BnF fr. 95 is a late 13th century manuscript containing Arthurian romances and other fictional and didactic texts. The Estoire del saint Graal and Merlin section is the most highly illuminated, with a rich marginal iconography, an unusual feature in the illustration of lay works and in these texts’ manuscript tradition. This article shows how in Merlin and its Vulgate Sequel marginal scenes overlap with widespread subjects in courtly and chivalric vernacular romances, in contrast with Latin and religious works. The reuse of similar patterns in principal and marginal miniatures, examined in the episode of the Battle of Danablaise, where King Arthur fights the Saxon King Rion, highlights the need for a comprehensive reading of text and images, taking into account the mise en page and the different levels of illustration in the manuscript.

L’infidélité dans le couple : Charles et Emma Bovary dans Madame Bovary de Flaubert et Dinah et Loulou dans Traversée de la Mangrove de Maryse Condé

Ce travail sur l’infidélité dans le couple traite les différentes sources de l’ennui ainsi que leurs conséquences dans la vie du couple. Les différentes opinions de différents auteurs sur la cause de l’infidélité dans le couple sont vues en long et en large. L’éducation féminine du XIXème siècle éclaire sur le handicap qui a entrainé certaines filles dans le malheur car l’éducation de l’époque ne les avait pas bien préparées pour devenir de bonnes épouses. Ce mémoire montre l’image de la religion dans ces deux oeuvres : Madame Bovary et Traversée de la mangrove. La question est de voir comment ces auteurs peignent la religion dans ces oeuvres et pourquoi ils adoptent l’infidélité pour sauver la femme de son ennui. Enfin, la comparaison de ces ennuis est faite afin de voir que dans ces couples, malgré le fait qu’ils appartiennent à des époques différentes, l’ennui dans le couple est le même. Ces auteurs ont procédé aux mêmes stratégies pour sauver le couple de son ennui. La morale critique et religieuse a été utilisée pour aborder ce thème, lorsque nous avons fait une lecture biblique de ces deux oeuvres.

Wolves in sheeps' clothing: Creationist manipulation of Kansas science standards

So the question that animates this paper is this: what happens when a state's education policy seeks to make popular social and religious values a central part of its education standards in direct confrontation with the Establishment Clause of the First Amendment of the U.S. Constitution? I will try to answer that question in three ways. First, I will examine the tactics used in the manipulation of curricula to reflect social and religious values, with special focus on the Kansas case. Second, I will try to ascertain the determinants of success in these efforts; under what conditions are movements to impose creation science on public school curricula likely to succeed, and when to fail? Third, I will try to place these struggles over educational curricula, and between religion and science, in broader context, focusing on what they tell us about the nature of public policy making in the contemporary United States.

Beyond the Threshold: Life in the New Russia

Amanda Sprang spent nine months, from September of 1995 to May of 1996, studying at Colby College's program in St. Petersburg, Russia. Through contacts made during previous trips to Russia in middle and high school, Amanda was able to quickly rekindle her old friendships and make new ones with many young Russians from different backgrounds. The following work is a collection of twelve essays about life in the New Russia. The essays are framed by a foreword and an epilogue that help place the entire work in a historical context. Although the theme of each essay emerges from a particular incident, within every story Amanda has addressed numerous topics relating to Russian life in today’s changing society. Her first essay, “Art Klinika," takes place in an avant-garde night club in St. Petersburg, and includes a brief yet impressionable, encounter with three young Russian men. “The Birthday Party” recalls a wild evening at the home of her close friend, showing how the Russians greet special occasions. Both the third and fourth essays take place in Moscow, where Amanda returns to visit old friends. These two essays portray the lives of the new economic elite in comparison with the average citizen, as well as show how young Russians face the new challenges that greet them. "Politics Russian Style" recalls a political rally in St. Petersburg, and attempts to shed light on the wacky political world of an infant democracy. Chapters Six through Ten take place away from the western cities of St. Petersburg and Moscow, as Amanda brings us to the cold, mysterious land of Siberia in the dead of winter. She recounts her five day train ride with a retired, high-powered, Communist party official, her experiences in the provincial city of Irkutsk, and a brief trip to a Buddhist monastery and, later, an excursion to Lake Baikal. Back in St. Petersburg, Chapter Eleven gives a humorous account of a ski trip with several Russian friends. Amanda finishes her work with her final chapter, “The Dacha," which describes a weekend spent at a Russian country home with her friend's family.

A gestão estratégica no terceiro setor: estudo de caso numa organização eclesiástica

This study has the objective to evaluate until which extent the adoption of the strategic planning by the Presbyterian Church of Manaus (IPM) expresses its effective fitting within the strategic management paradigm, whose ethos is the predominance of the instrumental-strategic rationality and the market-orientated logic in the managerial actions. It is assumed as a research initial hypothesis that the adoption of this technique by IPM represented an instrumental-strategic managerial action and a deliberated incorporation of market-orientated managerial parameters, strengthening some of the organizational studies¿ ultimate conclusions about the colonization of the third sector¿s organizations by the capitalist system logic. The research method foresees: (a) a bibliographical review about the themes ¿critical social theories¿, ¿strategic management¿, ¿third sector¿ and ¿religious organizations sociology¿; and (b) a case study at IPM, religious organization established at the state of Amazonas, branch of the Presbyterian Church of Brazil (IPB) and socially active according to religious aims and related (social care, cultural, etc.).

A relação homem-mundo em René Descartes e no Zen-Budismo

Este trabalho procura justapor duas visões do homem no mundo, a cartesiana e a zen-budista, ressaltando o aspecto fragmentador da primeira e o aspecto integrador da segunda. O objetivo básico é contribuir para maior articulação e integração do homem contemporâneo através de três movimentos. Primeiro, através da critica à concepçao racionalista, mecânica, prepotente e antinatural, fundada na lógica dual e antitética do paradigma da ciência e do pensamento ocidental em boa parte construido por René Descartes; Segundo, através da divulgação e da exposição enfática, em nosso meio acadêmico ocidental, da metafisica e da mística budistas, especialmente em sua versão Zen, que compreende o mundo em permanente transformação e construção como um todo articulado ao equilibrio universal, no qual as palavras, os conhecimentos e a percepção são meros signos passageiros que escondem a realidade cósmica. O movimento final pretende negar uma visão maniqueísta da realidade onde a oposição não é vista como a liquidação de um dos termos pelo outro, mas como a busca de uma nova síntese: a gestação, enfim, de um novo referencial do mundo - e aqui apenas se levanta a questão - a ser construído, quem sabe, a partir da integração dos paradigmas caracterizados hoje como ocidental e oriental.

Similaridades entre a psicoterapia centrada no cliente e o pensamento existencial de Soren Kierkegaard

Com o objetivo de contactar a existência de similaridades entre a terapia de Carl Rogers e o posicionamento existencial de Sören Kierkegaard, partiu-se do exame da obra do pensador dinamarquês, sua preocupação com o concreto, o singular, o homem como subjetividade, e os estágios - estético, ético e religioso - maneira como se processa sua existência. A seguir, após estudo do evoluir da teoria psicoterápica de Rogers, abrangendo as três fases, assinala-se a convergência de intuições e convicções que refletem perspectivas comuns aos dois pensadores. O próprio Rogers em artigo publicado em 1955 expressa seu agradecimento a Kierkegaard que, através de sua posição, levou-o a confiar e exprimir sua experiência. A análise da abordagem existenciaI da terapia rogeriana ressalta que, muito embora ele tenha nascido um século após Kierkegaard há várias pautas convergentes entre eles.

Atribuição de causalidade em presos, amputados e cegos: aceitação e luta contra o infortúnio

Os objetivos deste trabalho compreendem a determinação: (a) dos processos de atribuição de causalidade e responsabilidade empregados, por sujeitos presos, cegos e amputados, na explicação dos eventos que os vitimaram; (b) da relação entre os processos de atribuição de causalidade e as respostas de combate a situação; (c) da eficácia das teorias de busca de controle, mundo justo e atribuição defensiva na explicação dos eventos por parte dos sujeitos: (d) da influência do sentimento de auto-estima, crença no mundo justo, “locus" de controle e sentimento de religiosidade, na atribuição de causalidade; (e) de como os observadores emparelhados aos atores atribuição da causalidade e responsabilidade aos eventos vitimadores. A parte inicial consiste em uma revisão das principais contribuições teóricas ao fenômenos da atribuição de causalidade em psicologia social e das pesquisas a ele relacionadas; sua extensão se justifica pela inexistência de textos desta natureza em nossa língua. A segunda parte compreende a análise das respostas a conjunto de questionários e escalas fornecidas por 43 sujeitos presos por homicídio ou assalto, 40 amputados de membro superior ou inferior, 35 cegos congênitos ou adquiridos, e de 138 sujeitos observadores a eles emparelhados em idade, nível sócio-econômico e escolaridade. Os resultados indicam diferenças no processo de atribuição de causalidade empregado pelos sujeitos com perdas diversas e na utilização de princípios das três teorias consideradas. O mesmo se verifica quando se comparam sujeitos atores e observadores. Os dados mostram ainda relações entre as variáveis psicológicas e o processo de atribuição de causalidade, bem como a influência destas variáveis no processo de luta contra a perda sofrida.

A necessidade de afiliação: um levantamento crítico

Este trabalho pretendeu realizar um levantamento crítico das pesquisas efetuadas em torno da necessidade de afiliação. Partindo de explicações gerais, calcadas nos conceitos de aprendizagem e instinto chegou-se às contribuições mais recentes e específicas, que tendem a destacar, principalmente, a influência de variáveis de personalidade e de ordem afetiva no desenvolvimento da conduta afiliativa. Procurou-se assinalar os aspectos dessas contribuições que podem ser considerados ambíguos e contraditórios, buscando abranger questões metodológicas, conceituais e teóricas. Tentou-se, finalmente, - objetivando contribuir para o prolongamento da pesquisa relacionada com este tipo de motivação - sugerir a vinculação entre a necessidade de afiliação e algumas variáveis consideradas no estudo da atração interpessoal. A realização da pesquisa sugerida faz parte de futuro projeto da autora.

O mercado de opções de petrobras é Ineficiente? Um estudo a partir da estratégia delta-gama-neutra

Este trabalho tem como objetivo verificar se o mercado de opções da Petrobras PN (PETR4) é ineficiente na forma fraca, ou seja, se as informações públicas estão ou não refletidas nos preços dos ativos. Para isso, tenta-se obter lucro sistemático por meio da estratégia Delta-Gama-Neutra que utiliza a ação preferencial e as opções de compra da empresa. Essa ação foi escolhida, uma vez que as suas opções tinham alto grau de liquidez durante todo o período estudado (01/10/2012 a 31/03/2013). Para a realização do estudo, foram consideradas as ordens de compra e venda enviadas tanto para o ativo-objeto quanto para as opções de forma a chegar ao livro de ofertas (book) real de todos os instrumentos a cada cinco minutos. A estratégia foi utilizada quando distorções entre a Volatilidade Implícita, calculada pelo modelo Black & Scholes, e a volatilidade calculada por alisamento exponencial (EWMA – Exponentially Weighted Moving Average) foram observadas. Os resultados obtidos mostraram que o mercado de opções de Petrobras não é eficiente em sua forma fraca, já que em 371 operações realizadas durante esse período, 85% delas foram lucrativas, com resultado médio de 0,49% e o tempo médio de duração de cada operação sendo pouco menor que uma hora e treze minutos.
