The good, the bad and the ugly: The fall and resolution of Banco Espírito Santo

This case study – and accompanying teaching note – briefly describes the history of the Espírito Santo family, a banking dynasty who led one of Portugal’s leading economic and financial groups, along with its “crown jewel”, Banco Espírito Santo. It chronicles how the corporate governance issues at BES allowed the family to exploit the bank, its shareholders and its customers, so as to support its unprofitable non-financial businesses. This left the bank in a poor financial situation, which deteriorated beyond control, leaving regulators – whose actions are also analysed here – with no alternative, amidst a severe liquidity crisis, but to apply a resolution measure, pinning large losses on junior bondholders and shareholders before recapitalising the bank.

Vol, fraude et autres infractions semblables et Internet

Dans l’espace réel, l’identité d’une personne est clairement circonscrite à l’état civil et pleinement protégée par le droit interne des pays. Alors que dans le cyberespace, les contours de la notion sont plutôt flous, voire incertains. Le développement du commerce électronique et la croissance des transactions en ligne ont donné naissance au « crime » de l’usurpation d’identité. Et si l’usurpation d’identité a pu émerger, c’est grâce à la spécificité du médium, qui s’est avéré un terrain fertile aux abus des usurpateurs d’identité. Ce présent article étudie et analyse la fraude, le vol et l’escroquerie en tant qu’infractions économiques commises dans le cyberespace par le biais du système informatique. Il constate la désuétude et l’inefficacité des infractions prévues dans le droit pénal canadien relativement à l’incrimination du crime de l’usurpation d’identité et propose une solution basée sur des approches réglementaires, législatives et techniques.

La construction du verdict de culpabilité : magistrature pénale et production de vérité judiciaire au Brésil

L’objectif de cette thèse est de comprendre de quelle manière le juge décide de la culpabilité de l’accusé, notamment dans les affaires de vol et de trafic de stupéfiants. En s’appuyant sur le programme ethnométhodologique et sur une enquête ethnographique, la recherche se penche sur l’ensemble de pratiques et raisonnements présents dans l’activité décisionnelle des juges, afin de rendre visibles les savoirs d’action mobilisés pour décider de la culpabilité. La thèse montre que la prise de décision est fortement marquée par la présomption de culpabilité qui découle d’un processus de catégorisation des justiciables en tant que « voleurs » et « trafiquants ». Ces catégories typiques sont associées à l’image de l’ennemi, c’est-à-dire, l’individu insoumis et incapable d’un modus vivendi commun (Jakobs, 2009). Prenant appui sur les analyses empiriques réalisées, l’étude fait une analogie entre la figure de l’ennemi et le concept d’homo sacer (Agamben, 1997; 2002) en proposant finalement que le verdict de culpabilité se construit à l’intérieur d’un « camp » - c’est-à-dire, un lieu de suspension de l’ordre juridique (Agamben, 1997) – qui se structure, paradoxalement, au sein même de la justice pénale.

Daughters of Lilith : transgressive femininity in Bram Stoker’s late gothic fiction

Daughters of Lilith: Transgressive Femininity in Bram Stoker’s Late Gothic Fiction explore le thème de la transgression féminine dans quatre romans gothiques de Bram Stoker. En combinant les études féministes et les études de genre, cette thèse examine les différents visages de la dissidence féminine à travers Dracula (1897), The Jewel of Seven Stars (1903), The Lady of the Shroud (1909) et The Lair of the White Worm (1911). Dans ces textes, la transgression est incarnée par la femme hystérique, la mère monstrueuse, la femme exotique et la New Woman. De plus, le traitement de ces stéréotypes féminins révèle une certaine tolérance envers la dissension féminine chez l’auteur. Souvent perçu comme un écrivain conservateur, Stoker est plutôt qualifié de progressiste dans cette thèse. L’inclusion de personnages féminins forts et déterminés à travers ses romans ainsi que ses rapports avec plusieurs féministes et proto-féministes dans sa vie privée témoignent de sa libéralité envers les femmes. Sa largeur d’esprit semble d’ailleurs évoluer tout au long de sa carrière ainsi qu’avec la progression du mouvement suffragiste britannique, une période mouvante à la fin du dix-neuvième et au début du vingtième siècle.

Host-symbiont interactions of the primary endosymbiont of human head and body lice

The first mycetome was discovered more than 340 yr ago in the human louse. Despite the remarkable biology and medical and social importance of human lice, its primary endosymbiont has eluded identification and characterization. Here, we report the host-symbiont interaction of the mycetomic bacterium of the head louse Pediculus humanus capitis and the body louse P. h. humanus. The endosymbiont represents a new bacterial lineage in the -Proteobacteria. Its closest sequenced relative is Arsenophonus nasoniae, from which it differs by more than 10%. A. nasoniae is a male-killing endosymbiont of jewel wasps. Using microdissection and multiphoton confocal microscopy, we show the remarkable interaction of this bacterium with its host. This endosymbiont is unique because it occupies sequentially four different mycetomes during the development of its host, undergoes three cycles of proliferation, changes in length from 2–4 µm to more than 100 µm, and has two extracellular migrations, during one of which the endosymbionts have to outrun its host’s immune cells. The host and its symbiont have evolved one of the most complex interactions: two provisional or transitory mycetomes, a main mycetome and a paired filial mycetome. Despite the close relatedness of body and head lice, differences are present in the mycetomic provisioning and the immunological response.—Perotti, M. A., Allen, J. M., Reed, D. L., Braig, H. R.

Cheaters in mutualism networks

Mutualism-network studies assume that all interacting species are mutualistic partners and consider that all links are of one kind. However, the influence of different types of links, such as cheating links, on network organization remains unexplored. We studied two flower-visitation networks (Malpighiaceae and Bignoniaceae and their flower visitors), and divide the types of link into cheaters (i.e. robbers and thieves of flower rewards) and effective pollinators. We investigated if there were topological differences among networks with and without cheaters, especially with respect to nestedness and modularity. The Malpighiaceae network was nested, but not modular, and it was dominated by pollinators and had much fewer cheater species than Bignoniaceae network (28% versus 75%). The Bignoniaceae network was mainly a plant-cheater network, being modular because of the presence of pollen robbers and showing no nestedness. In the Malpighiaceae network, removal of cheaters had no major consequences for topology. In contrast, removal of cheaters broke down the modularity of the Bignoniaceae network. As cheaters are ubiquitous in all mutualisms, the results presented here show that they have a strong impact upon network topology.

Arquitetura da (in)segurança: estudando relações entre configuração espacial, artifícios de segurança e violência urbana no bairro Manaíra, João Pessoa, Paraíba

João Pessoa, the capital city of the state of Paraíba (Northeast Brazil), is reputed throughout the country as a quiet place, although it has been acquiring, over the past years, an urban character with social implications similar to those of major metropolitan Brazilian areas. The new situation is evident by the social inequalities, with the creation of confined spaces, which segregate and cause enclosure of the inhabitants, leading to death the public space. This study correlates accessibility in spatial structure with two types of crime data, burglary and robbery, recorded in 2008 and 2009, by the Secretaria de Segurança da Paraíba (The government agency public in charge of safety), in the district of Manaíra, an upper middle class neighborhood, which has, in recent times, been considered one of the most violent areas in João Pessoa. Sought to understand connections between these events and morpho-social aspects of the built environment, where examined the spatial properties, such as accessibility of the urban net, the presence of control measures, the safety of buildings and their uses. Spatial properties were also validated by the observation of pedestrian flows at strategic points of the study area. It was concluded that the presence of intense flows helps to attract potential thieves, physical security and control offers little protection

Floral visitors and reproductive strategies in five melittophilous species of Bignoniaceae in Southeastern Brazil

Com objetivo de avaliar as estratégias de polinização de espécies de Bignoniaceae, foram estudados a biologia floral e os visitantes florais de cinco espécies, três arbustivas do cerrado (Arrabidaea brachypoda (DC.) Bor., Jacaranda decurrens Cham. e Jacaranda oxyphylla Cham.) e duas lianas da orla da floresta estacional semidecidual (Arrabidaea samydoides (Cham.) Sandw. e Arrabidaea triplinervia H. Baill.), na região de Botucatu (22º52'20 S e 48(0)26'37 W), estado de São Paulo, sudeste do Brasil. Os períodos de florescimento, principalmente entre espécies do mesmo habitat, apresentaram sobreposição parcial. Observou-se que as cinco espécies são alogâmicas funcionais, melitófilas, nototríbicas, polinizadas principalmente por abelhas grandes de língua comprida. Algumas abelhas coletoras de pólen de tamanho médio e pequeno atuaram como polinizadoras ocasionais, enquanto outros visitantes foram pilhadores. Cada uma das Bignoniaceae apresentou um conjunto particular de polinizadores havendo apenas duas espécies comuns a mais de uma delas. Não houve partilha de polinizadores mesmo entre bignoniáceas que, no mesmo habitat, apresentaram períodos de florescimento simultâneo.

The Effects of Nectar-Robbing on Fruit Production in Sparattosperma leucanthum (Bignoniaceae)

Many animals behave as robbers or thieves of floral resources, causing damage to floral tissues or consuming resources used to attract pollinators, or producing effects similar to emasculation by reducing the pollen load in the anthers (which generally results in losses in terms of sexual reproduction). The present work examined the direct and indirect impacts caused by nectar-robbing on the reproductive success of Sparattosperma leucanthum. Different manipulations of the flowers were tested to determine if fruit production was influenced by the perforations made in the floral tissues (direct damage), and if there were changes in visitation frequencies or in the behaviors of effective pollinators (indirect damage). Perforations made by nectar robbers did not lower the reproductive success of the plant species studied. The bee Trigona spinipes was the most frequent visitor and caused the largest perforations in the calyx and corolla of S. leucanthum. Additionally, we noted the occurrence of pollen theft by this same bee in flowers that had been protected against nectar-robbing. These results suggest that if S. leucanthum had developed a mechanism of resistance to robbery by T spinipes it would probably have experienced even lower pollination levels as a result of reductions in the quantities of pollen available for transfer by effective pollinators. We were not able to evaluate if nectar depletion through robbery modified the behavior of the effective pollinators (bumblebees of the genus Bombus).

Biologia floral e sistema de reprodução de Merostachys riedeliana (Poaceae: Bambusoideae)

Merostachys riedeliana Rupr. é uma espécie monocárpica com floração cíclica e muito freqüente em sub-bosques de fragmentos florestais do sul do estado de Minas Gerais, Brasil. Sua biologia floral e seu sistema de reprodução foram estudados e comparados com os de outros bambus. Devido ao complexo sistema de rizomas, formam touceiras vigorosas no interior da floresta, ocorrendo a interrupção na produção de novos colmos meses antes do aparecimento das primeiras inflorescências. O início da floração maciça e da morte da população ocorreu em outubro de 1998 e maio de 1999, respectivamente, com pico de floração durante a estação quente e chuvosa (dezembro e janeiro). As inflorescências espiciformes possuem, em média, 29 espiguetas. Estas são hermafroditas com três anteras poricidas e dois estigmas plumosos que se expõem durante a antese. O pólen é abundante e facilmente liberado das anteras pelo vento ou pelos visitantes. Apis mellifera L. e Trigona spinipes (F.) foram os visitantes mais freqüentes, atuando como pilhadores de pólen e, ocasionalmente, através de movimentos vibratórios, como elementos auxiliares para a dispersão do pólen. A alta pluviosidade durante a floração e a escassez de vento no sub-bosque da floresta, podem diminuir a efetividade da anemofilia. No entanto, vários caracteres morfológicos das espiguetas, queda de folhas e o hábito espacialmente agrupado, apontam para uma polinização pelo vento. Testes de polinização controlada, mostraram que M. riedeliana é autocompatível (ISI 0,99). A auto-incompatibilidade não favorece a formação de frutos em clones vegetais, ao passo que a autocompatibilidade poderia resultar em uma elevada produção de sementes. Assim, a possível ocorrência de clones de M. riedeliana nos fragmentos florestais, originados pelo crescimento vegetativo durante os intervalos reprodutivos de 30-32 anos, poderiam explicar o alto investimento na produção de espiguetas e a formação de frutos provenientes da autocompatibilidade.

Entomofauna visitante de Belamcanda chinensis (L.) DC (Iridaceae) durante o período de floração

A study of the reproductive biology of B. chinensis (L.) DC. (Iridaceae) was realized comprising floral biology and breeding systems. The floral biology studies included analyses of nectar production, occurence of osmophores, corolla pigments, ultraviolet reflexion and absortion patterns, viability of pollen, pollinators and flower visitors. The breeding systems were studied taking into account the results of manual pollinators tests. B. chinensis is self-compatible bul cross-pollination is more frequent. The effective pollinators are Plebeia droryana (Friese, 1906) (45,7%), Trigona spinipes (Fabricius, 1793) (27,3%), Tetragonisca angustula (Latreille, 1811) (9,3%). Others insects visitors are considered nectar and pollen thieves. The flowering begins generally in January and February. The complete reproductive cicle, as here considered, begining with floral bud production ending with development of mature fruits, lasts January to June. Seed dispersion is ornitocoric.

Efeitos tóxicos de surfactantes fitossanitários para o peixe mato grosso (Hyphessobrycon eques)

Toxic effects of phytosanitary surfactants for jewel tetra (Hyphessobrycon eques). Surfactants are amphipatic molecules that reduce the surface tension of water and make up the inert components of pesticide formulations. Thus, the objectives of this study were: to estimate the lethal concentration (LC(I)50;96h); classify and evaluate water quality during testing of the following surfactants: Agral[registered trademark], Aterbane[registered trademark]BR, Ag-bem[registered trademark], Energic[registered trademark], Fixade[registered trademark] and Gotafix[registered trademark] for jewel tetra (Hyphessobrycon eques); and the signs of intoxication in the animals. For this, the fish were acclimated for ten days in the bioassay room. The animals were exposed to the surfactants in an entirely randomized design with three replications. The LC(I)(50;96h) of surfactant Agral[registered trademark] was 3.29 mg L-1; Aterbane[registered trademark] BR 8.21 mg L-1; Energic[registered trademark] 2.34 mg L-1; Gotafix[registered trademark] 4.37 mg L-1; Fixade[registered trademark] 3.38 mg L-1; and Ag-bem[registered trademark] 34.95 mg L-1. The variables of water quality were unchanged. The fish showed an increase in the opercular beating after exposure; 4 and 24 hours, loss of gasping ability; 48 hours, slow opercular beating; and 72 and 96 hours later, recovery. The surfactants Energic[registered trademark], Agral[registered trademark], Gotafix[registered trademark], Aterbane[registered trademark] BR and Fixade[registered trademark] can be classified as moderately toxics, and Ag-Bem[registered trademark] as slightly toxic for H. eques; this organism shows similar intoxication signs for all surfactants.

Flower mites decrease nectar availability in the rain-forest bromeliad Neoregelia johannis

Nectarivorous flower mites can reduce the volume of nectar available to pollinators. The effects of the flower mite Proctolaelaps sp. on nectar availability in flowers of a melittophilous bromeliad Neoregelia johannis (Bromeliaceae) was evaluated in a coastal rain forest in south-eastern Brazil. In a randomized block experiment utilizing 18 flower pairs, one per bromeliad ramet, pollinators (Bombus morio) and mites were excluded, and then nectar volume, sugar concentration and sugar mass were quantified over the anthesis period. Mites significantly reduced nectar volume early in the morning (6h00-8h00), but not later (10h00-12h00). Mites decreased total volume of nectar available up to 22%. Sugar concentration in nectar was higher earlier in the morning, and decreased between 10h00-12h00. The pronounced consumption of nectar by mites during the period of higher sugar concentration reduced the total amount of sugar available to pollinators by 31%. This is the first study showing that flower mites decrease nectar rewards in a melittophilous plant. Because nectar volume by itself incompletely describes nectar production rates and the effects of nectar removal by flower mites on the availability of sugar, our study highlights the inclusion of sugar content in future studies assessing the effects of thieves on nectar production rates.
