La stratégie de désinvestissement graduel des marchés financiers sécurise-t-elle réellement l’épargne ?
Authors: Direr Alexis , Yayi Éric 
Published: May 2018

Cet article étudie la validité empirique du mécanisme de sécurisation de l’épargne fondé sur le désinvestissement graduel en actifs risqués. Nous comparons ce mécanisme à une politique de constance de la part investie en actifs risqués à partir des données financières de cinq pays, pour des horizons variant de 5 à 30 ans. Nous utilisons différentes définitions du risque : l’écart type du rendement cumulé final, son degré de dissymétrie, la probabilité de perte ou la prime de risque réclamée par un investisseur pour passer d’une stratégie à l’autre. Contrairement aux recommandations habituelles des conseillers financiers, nos résultats ne montrent pas d’avantages tangibles de la stratégie de désinvestissement graduel en termes de réduction du risque à l’échéance du placement. L’hypothèse jointe d’épargne progressive et d’imperfection des marchés financiers rend la politique de désinvestissement graduel préférable à celle de constance de la part risquée mais d’une marge quantitativement faible.

Entrepreneurs politiques et engagement électoral
Authors: Guinaudeau Isabelle , Saurugger Sabine 
Published: May 2018

Résumé L’objectif de cet article est d’expliquer pourquoi le pouvoir exécutif présidé par Nicolas Sarkozy a tenu sa promesse électorale d’accorder plus d’autonomie aux universités. Alors que les projets politiques développés successivement depuis les années 1960 avaient échoué, la loi relative aux libertés et responsabilités des universités (LRU) fut adoptée en août 2007, soit moins de deux mois après les élections législatives. Combinant des cadres conceptuels issus de la sociologie politique et de l’analyse des politiques publiques, l’article fait émerger deux facteurs essentiels de la réalisation des promesses électorales : la mobilisation d’un entrepreneur politique lorsqu’il permet de renforcer à la fois les motivations et la capacité du pouvoir exécutif à faire ce qu’il a promis.
Chocolate City
Authors: Asch Chris Myers , Musgrove George Derek 
Published: May 2018

Monumental in scope and vividly detailed, Chocolate City tells the tumultuous, four-century story of race and democracy in our nation’s capital. Emblematic of the ongoing tensions between America’s expansive democratic promises and its enduring racial realities, Washington often has served as a national battleground for contentious issues, including slavery, segregation, civil rights, the drug war, and gentrification. But D.C. is more than just a seat of government, and authors Chris Myers Asch and George Derek Musgrove also highlight the city’s rich history of local activism as Washingtonians of all races have struggled to make their voices heard in an undemocratic city where residents lack full political rights. Tracing D.C.’s massive transformations--from a sparsely inhabited plantation society into a diverse metropolis, from a center of the slave trade to the nation’s first black-majority city, from “Chocolate City” to “Latte City”--Asch and Musgrove offer an engaging narrative peppered with unforgettable characters, a history of deep racial division but also one of hope, resilience, and interracial cooperation.
Extrapolating regional probability of drying of headwater streams using discrete observations and gauging networks
Authors: Beaufort Aurélien , Lamouroux Nicolas , Pella Hervé , Datry Thibault , Sauquet Eric 
Published: May 2018

Abstract. Headwater streams represent a substantial proportion of river systems and many of them have intermittent flows due to their upstream position in the network. These intermittent rivers and ephemeral streams have recently seen a marked increase in interest, especially to assess the impact of drying on aquatic ecosystems. The objective of this paper is to quantify how discrete (in space and time) field observations of flow intermittence help to extrapolate over time the daily probability of drying (defined at the regional scale). Two empirical models based on linear or logistic regressions have been developed to predict the daily probability of intermittence at the regional scale across France. Explanatory variables were derived from available daily discharge and groundwater-level data of a dense gauging/piezometer network, and models were calibrated using discrete series of field observations of flow intermittence. The robustness of the models was tested using an independent, dense regional dataset of intermittence observations and observations of the year 2017 excluded from the calibration. The resulting models were used to extrapolate the daily regional probability of drying in France: (i) over the period 2011–2017 to identify the regions most affected by flow intermittence; (ii) over the period 1989–2017, using a reduced input dataset, to analyse temporal variability of flow intermittence at the national level. The two empirical regression models performed equally well between 2011 and 2017. The accuracy of predictions depended on the number of continuous gauging/piezometer stations and intermittence observations available to calibrate the regressions. Regions with the highest performance were located in sedimentary plains, where the monitoring network was dense and where the regional probability of drying was the highest. Conversely, the worst performances were obtained in mountainous regions. Finally, temporal projections (1989–2016) suggested the highest probabilities of intermittence (> 35 %) in 1989–1991, 2003 and 2005. A high density of intermittence observations improved the information provided by gauging stations and piezometers to extrapolate the temporal variability of intermittent rivers and ephemeral streams.

Abstract. The oldest ice core records are obtained from the East Antarctic
Plateau. Water isotopes are key proxies to reconstructing past climatic
conditions over the ice sheet and at the evaporation source. The accuracy of
climate reconstructions depends on knowledge of all processes affecting water
vapour, precipitation and snow isotopic compositions. Fractionation processes
are well understood and can be integrated in trajectory-based Rayleigh
distillation and isotope-enabled climate models. However, a quantitative
understanding of processes potentially altering snow isotopic composition
after deposition is still missing. In low-accumulation sites, such as those
found in East Antarctica, these poorly constrained processes are likely to
play a significant role and limit the interpretability of an ice core's
isotopic composition. By combining observations of isotopic composition in vapour, precipitation,
surface snow and buried snow from Dome C, a deep ice core site on the East
Antarctic Plateau, we found indications of a seasonal impact of
metamorphism on the surface snow isotopic signal when compared to the initial
precipitation. Particularly in summer, exchanges of water molecules between
vapour and snow are driven by the diurnal sublimation–condensation cycles.
Overall, we observe in between precipitation events modification of the
surface snow isotopic composition. Using high-resolution water isotopic
composition profiles from snow pits at five Antarctic sites with different
accumulation rates, we identified common patterns which cannot be attributed
to the seasonal variability of precipitation. These differences in the
precipitation, surface snow and buried snow isotopic composition provide
evidence of post-deposition processes affecting ice core records in low-accumulation areas.
Genetic diversity and differentiation of invasive &lt;i&gt;Acacia longifolia&lt;/i&gt; in Portugal
Authors: Vicente Sara , Máguas Cristina , Trindade Helena 
Published: May 2018

Abstract. Acacia longifolia is an aggressive invader worldwide. This
species was brought to Portugal by the forestry services and is now
found throughout the country with very strong ecological and social
impacts. Although several ecological and physiological studies have
been carried out, molecular studies in this species are
sparse. Particularly, genetic variability evaluation in invasive
ranges clearly deserves more attention. The aim of this study was to
evaluate the genetic diversity and the genetic differentiation among
populations of the alien invasive A. longifolia under
different Mediterranean conditions. For that we studied three sandy
dune populations along the Portuguese coast: Osso da Baleia
(mesomediterranean), Pinheiro da Cruz and Vila Nova de Milfontes
(termomediterranean). All sampled acacia plants were located
underneath a pine forest, with the exception of the latter case
study, where we also sampled in a diversified habitat conditions
associated with the margins of agriculture fields. According to the
historical records, it was also possible to compare acacia samples
from original plantations and recently invaded areas. We have used
two molecular markers – inter-simple sequence repeats (ISSR) and
microsatellites (SSR). ISSR analysis showed that
A. longifolia populations at all sampled locations have
similar levels of diversity and a relatively low differentiation
(ΦPT=0.135). However, samples tended to cluster
according to the regional (macro-scale) collection
site. Microsatellites confirmed this low differentiation
pattern. Our results indicate that differences in phenology and
reproductive success observed during a previous study cannot be
accounted for by genetic diversity and differentiation
alone. Furthermore, our results taken together with historical
information of A. longifolia suggest a single original
introduction and a subsequent acclimation process.
Costumes e Justiça: a interpretação da norma no cabildo de Corrientes - 1588 a 1646
Authors: Martins Liz Araujo 
Published: May 2018

Esse texto foi desenvolvido pelo resultado de um projeto de pesquisa, financiado pela FAPESP. A proposta do projeto era ler e analisar as Actas Capitulares da cidade de Corrientes (1588 a 1646). A análise se fez com o propósito de investigar as leis e sua aplicação nesta cidade, tomando como hipótese as reflexões desenvolvidas pelo professor Rafael Ruiz2, em seu projeto “Direitos e Justiça nas Américas”. Tais reflexões consistem na idéia de que as leis na América Ibérica do século XVII eram heterogêneas e flexíveis, estavam sujeitas a daptações, a especificidades circunstanciais e a demandas locais.
REPRESENTAÇÕES DA SOCIEDADE BOLIVIANA EM SOLEDAD, DE BARTOLOMÉ MITRE
Authors: Troncozo Mayra Vanessa Villca 
Published: May 2018

Soledad foi escrita pelo argentino Bartolomé Mitre (1821- 1906) durante sua curta passagem pela Bolívia, entre 1846 e 1847. O romance apresenta uma clara dicotomia entre as representações da sociedade colonial e da nova sociedade independente. Neste artigo analisaremos essas representações criadas pelo autor para referir-se ao passado colonial e aos primeiros anos de história independente da Bolívia. Procuraremos demonstrar como Mitre, ao escrever Soledad, estava se posicionando politicamente e legitimando o projeto político do presidente José Ballivián.
TRAJETÓRIA DE UM PATRÍCIO: CONHECENDO RIZKALLAH JORGE TAHAN E A CONSTRUÇÃO DE SEU PODER SIMBÓLICO
Authors: Geraissati Renata 
Published: May 2018

O artigo pretende reconstruir a trajetória de um expoente imigrante sírio-libanês com ascendência armênia Rizkallah Jorge Tahan (1868-1949), tendo como foco a construção de seu poder simbólico dentro das comunidades que frequentou na cidade de São Paulo. Ao desembarcar no porto de Santos em 1895 fugiu da trajetória da maioria dos imigrantes desta nacionalidade que se tornavam mascates ao chegarem no Brasil. Rizkallah trabalhou com a fundição de cobre, algo que já fazia em sua terra natal. Após três anos na capital paulista inaugurou a Casa da Boia, balcão comercial baseado no comércio de elementos como “a boia sanitária”– o que permitiu seu enriquecimento e, o consequente investimento em uma série de obras nos centros “velho” e “novo” de São Paulo.
GÊNERO, MASCULINIDADES E ALCOOLISMO: BRASIL NO INÍCIO DO SÉCULO XX
Authors: Savian Zulemar Augusta Girotto 
Published: May 2018

A presente pesquisa tem como objetivo analisar, em uma perspectiva das relações de gênero, os discursos masculinos vinculados ao consumo de álcool no Brasil, no inicio do século XX. Através de pesquisa bibliográfica e da análise de propagandas de cerveja da época, busca-se compreender a relação entre a definição de masculinidade e o consumo de bebida alcoólica, e como foi possível a emergência das cervejarias brasileiras em um momento em que o consumo alcoólico passava a ser considerado um problema social e de saúde pública, sob o controle do Estado e do saber médico. O intenso debate sobre a questão do consumo excessivo de bebidas alcoólicas, posto naquele momento, fez com que os fabricantes de cerveja investissem em um novo significado de consumo, distante daquele condenado, na busca do consumidor, em particular, o masculino, das classes mais abastadas. As imagens projetadas nas propagandas estabelecem um perfil idealizado de masculinidade vinculado à elite do sudeste brasileiro, distinto daquele relacionado às classes mais pobres urbanas e vinculado a problemas sociais.
RISO E REGENERAÇÃO: O MEDIEVO DO SÉCULO XIV ATRAVÉS DO ESCRITO LITERÁRIO DE GIOVANNI BOCCACCIO
Authors: Zattera Amanda Cristina 
Published: May 2018

No presente artigo realizamos uma análise sobre uma importante obra literária do período tardo-medieval: Decamerão de Giovanni Boccaccio (1313-1375). Escrita na Florença do século XIV, ela apresenta, no teor de suas narrativas, resquícios de um contexto marcado pela ideia da Morte, tendo em vista as terríveis circunstâncias e consequências nefastas que a Peste Negra, desde 1347, havia trazido para a região europeia. Propomos então observar o otimismo e o riso como uma das formas de agir perante uma realidade de cotidianidade da morte.
WAKING LIFE E A MODERNIDADE LÍQUIDA
Authors: Wasak Aline Isabel , Moraes Anne Caroline de Rocha de , Oliveira Maybel Sulamita de , Martins Paula Marinelli 
Published: May 2018

Este artigo visa analisar o filme Waking Life, produzido nos Estados Unidos em 2001, como expressão de seu contexto social. A análise da conjuntura é dada a partir do conceito de Modernidade Líquida forjado pelo filósofo Zygmunt Bauman, conceito que faz referência ao período posterior a Segunda Guerra Mundial, onde ocorre a crise da ideia de Progresso e Civilização, que se estende até os dias atuais. A análise do filme como fonte histórica busca compreender como este expõe os questionamentos e contradições da sociedade em que ele foi produzido e consumido, revelando elementos que Bauman expõe em suatese.

ESPAÇOS INVISÍVEIS: ARTE E ARQUITETURA NA CIDADE CONTEMPORÂNEA
Authors: Junqueira ribeiro pinto Julia 
Published: May 2018

Arte e arquitetura partilham questões comuns dentro do campo ampliado da cultura, visando a compreensão do mundo contemporâneo, no qual a cidade genérica, regida por produções imateriais de valor, é expoente. Parte necessária à manutenção deste sistema são os espaços residuais, por exemplo aqueles comumente gerados em renovações urbanas especulativas. É tamanha a dificuldade de se lidar com eles, são espaços ignorados, quase invisíveis. Porém, nesses lugares onde o tecido da cidade afrouxa – a densidade diminui, assim como os fluxos –, ficam evidentes os valores, dinâmicas e fraquezas contemporâneas. Daí a potência de intervenções que chamam a atenção para esses locais. Assim, o presente trabalho analisa e compara práticas recentes no contexto brasileiro de três artistas-arquitetos – Lotes Vagos, de Louise Ganz; Vazadores e Calçada, de Rubens Mano; e Amnésias Topográficas I, Amnésias Topográficas II e Espaços Públicos Invisíveis, de Carlos Teixeira – para entender como eles lidam com a realidade espacial desse mundo capitalizado e fragmentado e ao mesmo tempo dinâmico e virtualizado.
Georges de La Tour and the Enigma of the Visible
Authors: Judovitz Dalia 
Published: May 2018

Celebrated due to the aura of mystery attached to his rediscovered works in the twentieth century, Georges de La Tour’s paintings continue to be an object of scholarly interest and public fascination. Exploring the representations of light, vision and the visible in his works, this interdisciplinary study raises seminal questions regarding the nature of painting and its artistic, theological, and conceptual implications. If the visible presents an enigma in La Tour’s pictorial works, this is because familiar objects of visible reality serve as emblems of an invisible, spiritual reality. La Tour’s pursuit of likeness between image and the natural world bears the influence of the Catholic Reform’s call for the revitalization of religious imagery in the wake of Protestant iconoclastic outbreaks. Like the books shown in his paintings which are asking to be read, La Tour’s paintings are examined not just as visual depictions but also as instruments of insight, which ask to be deciphered rather than merely seen. La Tour’s paintings show how the figuration of faith as spiritual passion and illumination challenges the meanings attached to the visual realm of painterly expression. This study shows that La Tour’s emphasis on spiritual insight opens up a broader artistic, philosophical and conceptual reflection on the conditions of possibility of painting and its limitations as a visual medium. By scrutinizing what is seen and how and by questioning the position of the beholder, his works encourage meditation on the role of painting and its engagements with the visible world.

Fenomenologia cognitiva
Authors: Jorba Marta 
Published: May 2018

Cognitive phenomenology Resum: La naturalesa i les característiques del pensament conscient han ocupat la filosofia i altres ciències al llarg de la història. Darrerament, però, ha sorgit la pregunta per les propietats fenomèniques del pensament, això és, pel caràcter qualitatiu de les experiències del pensar o el que s’ha anomenat ‘fenomenologia cognitiva’. L’existència d’aquest tipus de consciència fenomènica té un estatut controvertit i trobem diverses posicions en la filosofia de la ment contemporània. En aquest article s’introdueix la qüestió, s’explica quina és la importància del tema, quines visions i arguments principals trobem en la literatura i quins són els elements que juguen un paper rellevant en el debat. Finalment es conclou apuntant possibles desenvolupament futurs en aquest àmbit de recerca. Abstract: The nature and characterization of conscious thought has occupied philosophy and the sciences across history. Lately, though, several authors have raised the question of the phenomenal properties of thought, that is, of the qualitative character of experiences of thinking or what has been called ‘cognitive phenomenology’. The existence of this kind of phenomenal consciousness has a controversial status and we find several views within contemporary philosophy of mind. In this article I introduce the question and present the importance of the topic, together with the main views and arguments we find in the literature and the elements that play a central role in the debate. I conclude with possible future developments for this research area. Palabras clave: consciència, experiència, caràcter fenomènic, pensament, pensar, intencionalitat.

Exigencias éticas del prosumidor-ciudadano frente a las empresas
Authors: Medina-Vicent Maria 
Published: May 2018

Ethical requirements of the prosumer-citizen facing companies Resumen: Los procesos de recesión económica y los cambios políticos que se están desarrollando en las sociedades occidentales, plantean una disyuntiva sobre el papel social de las empresas y su modo de relacionarse con el público. Se ha producido el despertar de consumidores/as conscientes de su poder, tanto como creadores/as de contenidos a través de los espacios digitales, como de vigilantes activos de las acciones de empresas y gobiernos. Ante esta realidad, las organizaciones no pueden actuar sin atender al entorno, deben reconocer su responsabilidad social y responder a las demandas de sus stakeholders a través de una gestión empresarial ética y comunicativa. En el presente artículo se reflexiona en torno a una propuesta de ética empresarial de corte discursivo capaz de responder a las exigencias sociales y promover una comunicación transparente que incorpore los intereses de los grupos afectados por la actividad empresarial. Abstract: The economic crisis and the political changes that are taking place in Western societies set out a dilemma about the social role of companies and their social interactions. Nowadays, consumers have become aware of their power, both as creators of content through digital tools, as active guards of the actions of companies and governments. In front of this, organizations cannot act without pay attention to their environment; companies must recognize their social responsibility and respond to the stakeholders demands through an ethical and communicative management. We’ll explain a business ethics based on a discursive model, because it can be useful to attend social demands, to promote transparent communication, and to incorporate the interests of those affected by business activity.
