During the period in question, large ice drifts transported incalculable numbers of icebergs, ice fields and ice floes from the Antarctica into the South Atlantic, confronting long-journeying sailing ships on the Cape Horn route with considerable danger. As is still the case today, the ice drifts generally tended in a northeasterly direction. Thus it can be assumed that the ice masses occuring near Cape Horn and in the South Atlantic originated in Graham Land and the South Shetland Islands, while those found in the Pacific will have come from Victoria Land. The masses drifting to Cape Horn, Isla de los Estados, the Falkland Islands and occasionally as far as the Tristan da Cunha Group are transported by the West Wind Drift and Falkland Current, diverted by the Brazil Current. The Bouvet and Agulhas Currents have little influence here. The great ice masses repeatedly reached points beyond the "outermost drift ice boundery" calculated in the course of the years, to continue on in the direction of the equator. The number of sailing ships which fell victim to the ice drifts while rounding Cape Horn can only be surmised; they simply disappeared without a trace in the expanses of the South Atlantic. Until the end of the 1900s the dangers presented by ice were less serious for westward-bound ships than for the "homeward-bounders" travelling from West to East. Following the turn of the century, however, the risk for "onwardbounders" increased significantly. Whether the ice drifts actually grew in might or whether the more frequent and more detailed reports led to this impression, could never be ascertained by the German Hydrographie Office. In the forty-one years between 1868 and 1908, ten light, ten medium and nine heavy ice years were counted, and only twelve years in which no reports of ice were submitted to the German Hydrographie Office. "One of the most terrible dangers threatening ships on their return from the Pacific Ocean," the pilot book for the Atlantic Ocean warns, "is the encounter with ice, to be expected south of the 50th parallel (approx.) in the Pacific and south of the 40th parallel (approx.) in the South Atlantic." Following the ice drift of 1854-55, thought to be the first ever recorded, the increasing numbers of sailing ships rounding Cape Horn were frequently confronted with drifts of varying sizes or with single icebergs. Then from 1892-94, a colossal ice drift crossed the path of the sailships in three stages. Several sailing ships collided with the icebergs and could be counted lucky if they survived with heavy damage to the bow and the fo regear. The reports on those which vanished for ever in the ice masses are hardly of investigative value. The English suffered particularly badly in the ice-plagued waters; their captains apparently sailed courses that led more freqently through drifts than did the sailing instructions of the German Hydrographic Office. Thus, among others, Capt. Jarvis' DUNTRUNE, also the STANMORE, ARTHURSTONE and LORD RANOCH as well as the French GALATHEE and CASHMERE all collided with icebergs. The crew of the AETHELBERTH panicked after a collision and took to their lifeboats. It was only after the ship detached itself from the iceberg it had rammed that the men returned to it and continued their journey. The TEMPLEMORE, on the other hand, had to be abandoned for good. Of the German sailing ships, the FLOTOW is to be mentioned here, and in the third phase of the drift the American SAN JOAQUIN lost a large proportion of its rigging. In the 20th century ice drifts continued to cross the courses of the Cape Horn ships. 1906 and 1908 were recorded as particularly heavy ice years. In 1908-09 both the FALKLANDBANK and the TOXTETH fell prey to ice, or so it was assumed during the subsequent Maritime Board proceedings. For the most part the German sailing ships were spared greater damages by sea. Their captains sent detailed ice reports to the German Hydrographic Office, which gratefully welcomed the information and partially incorporated it in the third and final edition of the "Pilot Book for the Atlantic Ocean." From the end of 1926 until the beginning of 1928, the last of the large sailing ships were once again confronted with "tremendous masses of icebergs and ice drifts." Reports of this period originated above all on the P-Liners PADUA, PAMIR, PASSAT, PEKING, PINNAS, PRIWALL and the ships of Gustav Erikson's fleet. The fate of the training sailship ADMIRAL KARPFANGER in connection with the ice in early 1938 was never clearly determined by the Maritime Board proceedings. Collision with an iceberg, however, is thought to be the most likely cause of accident. Today freight sailing ships no longer cross the oceans. The Cape Horn route is relatively insignificant for engine-powered ships and icebergs can be spotted in plenty of time by modern navigation technology ... The large ice drifts are no longer a menace, but only a marginal note in the final chapter of the history of transoceanic sailing.

El modelo de empresa-red constituye un desafío para los sistemas de relaciones laborales. Dicho modelo cuestiona el papel de las instituciones colectivas de trabajo, concebidas históricamente en el marco de una organización integrada verticalmente según el modelo fordista. En efecto, la empresa dispersa o el recurso a la subcontratación son contextos cada vez más habituales, en los cuales la organización del trabajo se encuentra disociada de la empresa en sentido jurídico y patrimonial, y donde se establecen relaciones de trabajo triangulares de facto entre empresa principal, empresa de servicios y trabajadores. La búsqueda de respuestas a esta problemática apunta a la reconstrucción de solidaridades entre los trabajadores, pasando por la acción de los representantes de los trabajadores. A partir de un estudio de casos llevado a cabo en dos industrias de flujo, la industria nuclear y la petroquímica, este artículo se propone analizar los efectos de la triangulación de la relación salarial a nivel de planta, y dos procesos experimentales de organización sindical y de negociación colectiva territorial que buscan dar respuesta a la problemática de la subcontratación. El artículo analiza los resultados y límites de dichas experiencias para reconstruir una “comunidad de trabajo” inclusiva de los trabajadores subcontratistas.

Based on the results of an ethnographic study with people diagnosed with schizophrenia and their relatives in Barcelona and Tarragona along one year, I problematize the transformation of roles and relationships inside the household from the first burst and the assignation of a diagnosis as rite of passage. I appeal to a cultural interpretation of family, understanding the family group as a specific ethnoscape. I analyze the chronicity meaning, and its consequences in the conformation of the “role of sick person” in the context of parental relationships. I also discuss the paradoxes in terms of autonomy for the affected persons because of the projection of cultural connotation of chronicity.

In recent years the concept of "Land Stewardship" has gained a great importance. In short, it means that local entities and individuals can protect enclave of high ecological and cultural value. This vision has been effective in some places in the world with success. For example, the “Projeto Sempre Viva”, created in the town of Mucugê, a place located in one of Brazil´s most renowned Natural Protected Areas: the Chapada Diamantina (State of Bahia). We had looked over the available information about this project on the Internet, as well as a personal visit that was made to the site to know it and to have the possibility to talk to their managers. On this basis, it has been reached to the conclusion that this project, born to protect a Sempre Viva´s endemic species in danger of extinction, has turned into an important site for tourism and environmental education, completed with the preservation of the cultural identity of this region which is linked to diamond mining.

El discernimiento de espíritus ha sido a lo largo de la historia del cristianismo un mecanismo fundamental para el control del acceso al carisma. Su desarrollo ha estado profundamente ligado a los cambios en la estructura social de las iglesias. Por ello buscamos aportar nuevas miradas sobre este dispositivo, analizándolo en el contexto de las periferias cristianas. Específicamente centraremos nuestro análisis en las iglesias evangélicas aborígenes mocoví del suroeste de la provincia del Chaco en Argentina. Nos aproximaremos a estas cuestiones a partir del análisis a la estructura social de estas iglesias, sus concepciones sobre los vínculos con las potencias no-humanas, la gestión de salud y enfermedad y la experiencia del culto.

The role of Constitutional Courts in deeply divided societies is complicated by the danger that the salient societal cleavages may influence judicial decision-making and, consequently, undermine judicial independence and impartiality. With reference to the decisions of the Constitutional Court of Bosnia-Herzegovina, this article investigates the influence of ethno-nationalism on judicial behaviour and the extent to which variation in judicial tenure amplifies or dampens that influence. Based on a statistical analysis of an original dataset of the Court’s decisions, we find that the judges do in fact divide predictably along ethno-national lines, at least in certain types of cases, and that these divisions cannot be reduced to a residual loyalty to their appointing political parties. Contrary to some theoretical expectations, however, we find that long-term tenure does little to dampen the influence of ethno-nationalism on judicial behaviour. Moreover, our findings suggest that the longer a judge serves on the Court the more ethno-national affiliation seems to influence her decision-making. We conclude by considering how alternative arrangements for the selection and tenure of judges might help to ameliorate this problem.

This article considers how far women's rights have improved in Afghanistan since the intervention by the international community in 2001. It examines this question through the author's experience of working with an Afghan women's writing group. It looks at the tension between allowing Afghan women to voice their experiences, and the danger of their writing embracing depictions of the female as ‘victim’. It concludes that while depictions of Afghan womanhood may appear to promote ‘negative’ images, the women themselves offer positive role models.

La vision joue un rôle très important dans la prévention du danger. La douleur a aussi pour fonction de prévenir les lésions corporelles. Nous avons donc testé l’hypothèse qu’une hypersensibilité à la douleur découlerait de la cécité en guise de compensation sensorielle. En effet, une littérature exhaustive indique qu’une plasticité intermodale s’opère chez les non-voyants, ce qui module à la hausse la sensibilité de leurs sens résiduels. De plus, plusieurs études montrent que la douleur peut être modulée par la vision et par une privation visuelle temporaire. Dans une première étude, nous avons mesuré les seuils de détection thermique et les seuils de douleur chez des aveugles de naissance et des voyants à l’aide d’une thermode qui permet de chauffer ou de refroidir la peau. Les participants ont aussi eu à quantifier la douleur perçue en réponse à des stimuli laser CO2 et à répondre à des questionnaires mesurant leur attitude face à des situations douloureuses de la vie quotidienne. Les résultats obtenus montrent que les aveugles congénitaux ont des seuils de douleur plus bas et des rapports de douleur plus élevés que leurs congénères voyants. De plus, les résultats psychométriques indiquent que les non-voyants sont plus attentifs à la douleur. Dans une deuxième étude, nous avons mesuré l’impact de l'expérience visuelle sur la perception de la douleur en répliquant la première étude dans un échantillon d’aveugles tardifs. Les résultats montrent que ces derniers sont en tous points similaires aux voyants quant à leur sensibilité à la douleur. Dans une troisième étude, nous avons testé les capacités de discrimination de température des aveugles congénitaux, car la détection de changements rapides de température est cruciale pour éviter les brûlures. Il s’est avéré que les aveugles de naissance ont une discrimination de température plus fine et qu’ils sont plus sensibles à la sommation spatiale de la chaleur. Dans une quatrième étude, nous avons examiné la contribution des fibres A∂ et C au traitement nociceptif des non-voyants, car ces récepteurs signalent la première et la deuxième douleur, respectivement. Nous avons observé que les aveugles congénitaux détectent plus facilement et répondent plus rapidement aux sensations générées par l’activation des fibres C. Dans une cinquième et dernière étude, nous avons sondé les changements potentiels qu’entrainerait la perte de vision dans la modulation descendante des intrants nociceptifs en mesurant les effets de l’appréhension d’un stimulus nocif sur la perception de la douleur. Les résultats montrent que, contrairement aux voyants, les aveugles congénitaux voient leur douleur exacerbée par l’incertitude face au danger, suggérant ainsi que la modulation centrale de la douleur est facilitée chez ces derniers. En gros, ces travaux indiquent que l’absence d’expérience visuelle, plutôt que la cécité, entraine une hausse de la sensibilité nociceptive, ce qui apporte une autre dimension au modèle d’intégration multi-sensorielle de la vision et de la douleur.

A presente dissertação – A Institucionalização no Feminino: que repercussões na Reintegração (Trajectórias de vida e dimensão dos factores de (des) protecção na transmissão intergeracional das jovens que saíram da CIJE de Castelo Branco no período de 1995-2000) – foi realizada no âmbito do VI Curso de Mestrado em Serviço Social. O objecto desta dissertação centrou-se na análise das trajectórias de vida de mulheres adultas que durante a sua infância estiveram internadas na Instituição Casa de Infância e Juventude de Castelo Branco e cuja desinstitucionalização ocorreu no período de 1995 a 2000, considerando como critério a residência das jovens no Distrito de Castelo Branco. Para a prossecução desta investigação, adoptou-se uma metodologia qualitativa. Recorreu-se à análise documental e a entrevistas semi-directivas efectuadas a nove jovens. Com esta investigação pretendeu-se estudar as trajectórias para a obtenção de dados sobre a experiência de vida, o seu processo de autonomização e de que forma a medida de institucionalização se reproduziu nos descendentes, e se estes constam igualmente das crianças e jovens com medida de protecção, nomeadamente de acolhimento institucional. Relativamente aos objectivos, pretendemos: analisar o percurso de vida das jovens com medida de acolhimento institucional; identificar a avaliação das jovens sobre o seu processo de internamento e a experiência de vida; identificar a forma como estas jovens se relacionam com a percepção do conceito formal da lei de “Perigo”; analisar a autonomia de vida face à família, à inserção profissional e eventual ligação face aos sistemas de protecção social; e analisar a situação e as expectativas face às jovens sem filhos. Dos resultados obtidos na presente investigação, podemos concluir que, após a medida de internamento, a maioria das jovens integrou a família de origem. Algumas valorizam este regresso, ressalvando as dificuldades de adaptação à sua família, e à própria comunidade. A maioria das jovens constituíram agregado próprio, revelando capacidades parentais na educação dos seus filhos, e proporcionando-lhes uma infância segura e feliz, assegurando de forma responsável as suas necessidades tendo em vista a sua segurança, saúde, formação, educação e desenvolvimento.

Thomas De Quincey’s essay ‘Levana and Our Ladies of Sorrow’ provided Dario Argento with the spark of an idea, which was further ignited by tales from his then wife, Daria Nicolodi, who told him of her grandmother’s stay at a music school which was run by a coven of witches. From these sources Argento came up with the mythology of The Three Mothers, which were to feature in three of his films: Suspiria (1977), Inferno (1980) and La terza madre/The Mother of Tears (2007). This article will examine the occult and esoteric sources of The Three Mothers trilogy, and explore how these references work to create a series of films that may superficially appear to use the supernatural and occult to create scares, but actually incorporate elements of Western Esotericism rather than traditional Christian images of evil. By doing this, these films transcend their apparent flaws (in terms of shallow plot and character development, a common complaint directed toward many Italian horror films) and instead imbue the mise-enscene itself with meaning, character and narrative. Although the films are situated within the Gothic genre, and in many respects follow traditional Gothic lines with witchcraft and the occult becoming synonymous with evil, I will argue that the films actually belong to the long tradition of art forms that have attempted to investigate the allure and the danger of occult exploration.

Abstract : Adverse drug reactions (ADRs) are undesirable effects caused after administration of a single dose or prolonged administration of drug or result from the combination of two or more drugs. Idiosyncratic drug reaction (IDR) is an adverse reaction that does not occur in most patients treated with a drug and does not involve the therapeutic effect of the drug. IDRs are unpredictable and often life-threatening. Idiosyncratic reaction is dependent on drug chemical characteristics or individual immunological response. IDRs are a major problem for drug development because they are usually not detected during clinical trials. In this study we focused on IDRs of Nevirapine (NVP), which is a non-nucleoside reverse transcriptase inhibitor used for the treatment of Human Immunodeficiency Virus (HIV) infections. The use of NVP is limited by a relatively high incidence of skin rash. NVP also causes a rash in female Brown Norway (BN) rats, which we use as animal model for this study. Our hypothesis is that idiosyncratic skin reactions associated with NVP treatment are due to post-translational modifications of proteins (e.g., glutathionylation) detectable by MS. The main objective of this study was to identify the proteins that are targeted by a reactive metabolite of Nevirapine in the skin. The specific objectives derived from the general objective were as follow: 1) To implement the click chemistry approach to detect proteins modified by a reactive NVP-Alkyne (NVP-ALK) metabolite. The purpose of using NVP-ALK was to couple it with Biotin using cycloaddition Click Chemistry reaction. 2) To detect protein modification using Western blotting and Mass Spectrometry techniques, which is important to understand the mechanism of NVP induced toxicity. 3) To identify the proteins using MASCOT search engine for protein identification, by comparing obtained spectrum from Mass Spectrometry with theoretical spectrum to find a matching peptide sequence. 4) To test if the drug or drug metabolites can cause harmful effects, as the induction of oxidative stress in cells (via protein glutathionylation). Oxidative stress causes cell damage that mediates signals, which likely induces the immune response. The results showed that Nevirapine is metabolized to a reactive metabolite, which causes protein modification. The extracted protein from the treated BN rats matched 10% of keratin, which implies that keratin was the protein targeted by the NVP-ALK.

In 2014 over 70% of people in Great Britain accessed the Internet every day. This resource is an optimal vector for malicious attackers to penetrate home computers and as such compromised pages have been increasing in both number and complexity. This paper presents X-Secure, a novel browser plug-in designed to present and raise the awareness of inexperienced users by analysing web-pages before malicious scripts are executed by the host computer. X-Secure was able to detect over 90% of the tested attacks and provides a danger level based on cumulative analysis of the source code, the URL, and the remote server, by using a set of heuristics, hence increasing the situational awareness of users browsing the internet.
