Cultural studies as the new humanities

The purpose of this study is to argue that Cultural Studies may be regarded as the new humanities. Cultural Studies focus on ethnic, post-colonial, communication, anthropological, ethnographic and feminist studies, and only ‘very marginally’ have they shown an interest in literature and literary studies (Aguiar & Silva, 2008). But those fields, which ‘Social Science’ rather than the ‘Arts’ have invested in (Ibid., p. 254), are the touchstone of modernity. Today, the concept we have of humankind is, to a large extent, played out in these areas. The questioning of both humankind and modernity has as backdrop the technologically-driven shift of culture from word to image (Martins, 2011 a). My proposal takes into account this debate, while underscoring how Cultural Studies are engaged in what is current and contemporary, which means, in the present and everyday life.

Small intestinal inflammation following oral infection with Toxoplasma gondii does not occur exclusively in C57BL/6 mice: review of 70 reports from the literature

Small intestinal immunopathology following oral infection with tissue cysts of Toxoplasma gondii has been described in C57BL/6 mice. Seven days after infection, mice develop severe small intestinal necrosis and succumb to infection. The immunopathology is mediated by local overproduction of Th1-type cytokines, a so-called "cytokine storm". The immunopathogenesis of this pathology resembles that of inflammatory bowel disease in humans, i.e., Crohn's disease. In this review, we show that the development of intestinal pathology following oral ingestion of T. gondii is not limited to C57BL/6 mice, but frequently occurs in nature. Using a Pubmed search, we identified 70 publications that report the development of gastrointestinal inflammation following infection with T. gondii in 63 animal species. Of these publications, 53 reports are on accidental ingestion of T. gondii in 49 different animal species and 17 reports are on experimental infections in 19 different animal species. Thus, oral infection with T. gondii appears to cause immunopathology in a large number of animal species in addition to mice. This manuscript reviews the common features of small intestinal immunopathology in the animal kingdom and speculates on consequences of this immunopathology for humankind.

Metastatic leishmaniasis. A chronic inflammatory response to Leishmania's viral endosymbiont.

Leishmania parasites have been plaguing humankind for centuries as a range of skin diseases named the cutaneous leishmaniases (CL). Carried in a hematophagous sand fly, Leishmania usually infests the skin surrounding the bite site, causing a destructive immune response that may persist for months or even years. The various symptomatic outcomes of CL range from a benevolent self- healing reddened bump to extensive open ulcerations, resistant to treatment and resulting in life- changing disfiguration. Many of these more aggressive outcomes are geographically isolated within the habitats of certain Neotropical Leishmania species; where about 15% of cases experience metastatic complications. However, despite this correlation, genetic analysis has revealed no major differences between species causing the various disease forms. We have recently identified a cytoplasmic dsRNA virus within metastatic L. guyanensis parasites that acts as a potent innate immunogen capable of worsening lesionai inflammation and prolonging parasite survival. The dsRNA genome of Leishmania RNA virus (LRV) binds and stimulates Toll-Like-Receptor-3 (TLR3), inducing this destructive inflammation, which we speculate as a factor contributing to the development of metastatic disease. This thesis establishes the first experimental model of LRV-mediated leishmanial metastasis and investigates the role of non-TLR3 viral recognition pathways in LRV-mediated pathology. Viral dsRNA can be detected by various non-TLR3 pattern recognition receptors (PRR); two such PRR groups are the RLRs (Retinoic acid-inducible gene 1 like receptors) and the NLRs (nucleotide- binding domain, leucine-rich repeat containing receptors). The RLRs are designed to detect viral dsRNA in the cytoplasm, while the NLRs react to molecular "danger" signals of cell damage, often oligomerizing into molecular scaffolds called "inflammasomes" that activate a potent inflammatory cascade. Interestingly, we found that neither RLR signalling nor the inflammasome pathway had an effect on LRV-mediated pathology. In contrast, we found a dramatic inflammasome independent effect for the NLR family member, NLRP10, where a knockout mouse model showed little evidence of disease. This phenotype was mimicked in an NLR knockout with which NLRP10 is known to interact: NLRC2. As this pathway induces the chronic inflammatory cell lineage TH17, we investigated the role of its key chronic inflammatory cytokine, IL-17A, in human patients infected by L. guyanensis. Indeed, patients infected with LRV+ parasites had a significantly increased level of IL-17A in lesionai biopsies. Interestingly, LRV presence was also associated with a significant decrease in the correlate of protection, IFN-y. This association was repeated in our murine model, where after we were able to establish the first experimental model of LRV-dependent leishmanial metastasis, which was mediated by IL-17A in the absence of IFN-y. Finally, we tested a new inhibitor of IL-17A secretion, SR1001, and reveal its potential as a Prophylactic immunomodulator and potent parasitotoxic drug. Taken together, these findings provide a basis for anti-IL-17A as a feasible therapeutic intervention to prevent and treat the metastatic complications of cutaneous leishmaniasis. -- Les parasites Leishmania infectent l'homme depuis des siècles causant des affections cutanées, appelées leishmanioses cutanées (LC). Le parasite est transmis par la mouche des sables et réside dans le derme à l'endroit de la piqûre. Au niveau de la peau, le parasite provoque une réponse immunitaire destructrice qui peut persister pendant des mois voire des années. Les symptômes de LC vont d'une simple enflure qui guérit spontanément jusqu' à de vastes ulcérations ouvertes, résistantes aux traitements. Des manifestations plus agressives sont déterminées par les habitats géographiques de certaines espèces de Leishmania. Dans ces cas, environ 15% des patients développent des lésions métastatiques. Aucun «facteur métastatique» n'a encore été trouvé à ce jour dans ces espèces. Récemment, nous avons pu identifier un virus résidant dans certains parasites métastatiques présents en Guyane française (appelé Leishmania-virus, ou LV) et qui confère un avantage de survie à son hôte parasitaire. Ce virus active fortement la réponse inflammatoire, aggravant l'inflammation et prolongeant l'infection parasitaire. Afin de diagnostiquer, prévenir et traiter ces lésions, nous nous sommes intéressés à identifier les composants de la voie de signalisation anti-virale, responsables de la persistance de cette inflammation. Cette étude décrit le premier modèle expérimental de métastases de la leishmaniose induites par LV, et identifie plusieurs composants de la voie inflammatoire anti-virale qui facilite la pathologie métastatique. Contrairement à l'homme, les souris de laboratoire infectées par des Leishmania métastatiques (contenant LV, LV+) ne développent pas de lésions métastatiques et guérissent après quelques semaines d'infection. Après avoir analysé un groupe de patients atteints de leishmaniose en Guyane française, nous avons constaté que les personnes infectées avec les parasites métastatiques LV+ avaient des niveaux significativement plus faibles d'un composant immunitaire protecteur important, appelé l'interféron (IFN)-y. En utilisant des souris génétiquement modifiées, incapables de produire de l'IFN-y, nous avons observé de telles métastases. Après inoculation dans le coussinet plantaire de souris IFN-y7" avec des parasites LV+ ou LV-, nous avons démontré que seules les souris infectées avec des leishmanies ayant LV développent de multiples lésions secondaires sur la queue. Comme nous l'avons observé chez l'homme, ces souris sécrètent une quantité significativement élevée d'un composant inflammatoire destructeur, l'interleukine (IL)-17. IL-17 a été incriminée pour son rôle dans de nombreuses maladies inflammatoires chroniques. On a ainsi trouvé un rôle destructif similaire pour l'IL-17 dans la leishmaniose métastatique. Nous avons confirmé ce rôle en abrogeant IL-17 dans des souris IFN-y7- ce qui ralentit l'apparition des métastases. Nous pouvons donc conclure que les métastases de la leishmaniose sont induites par l'IL-17 en absence d'IFN-v. En analysant plus en détails les voies de signalisation anti-virale induites par LV, nous avons pu exclure d'autres voies d'activation de la réponse inflammatoire. Nous avons ainsi démontré que la signalisation par LV est indépendante de la signalisation inflammatoire de type « inflammasome ». En revanche, nous avons pu y lier plusieurs autres molécules, telles que NLRP10 et NLRC2, connues pour leur synergie avec les réponses inflammatoires. Cette nouvelle voie pourrait être la cible pour des médicaments inhibant l'inflammation. En effet, un nouveau médicament qui bloque la production d'IL-17 chez la souris s'est montré prometteur dans notre modèle : il a réduit le gonflement des lésions ainsi que la charge parasitaire, indiquant que la voie anti-virale /inflammatoire est une approche thérapeutique possible pour prévenir et traiter cette infection négligée.

Commercialization of Biopharmaceuticals

Biotekniikkaa pidetään yhtenä lupaavimmista nykyään tunnetuista teknologioista. Biotekniikan alalta erityisesti uusien lääkeaineiden kehittely on saavuttanut huomiota julkisuudessa. Biotekniikkaa lääkeaineiden kehittämiseen soveltavien yritysten määrä on kasvanut nopeasti viimeisen vuosikymmenen aikana, mutta tämänhetkiset tulokset osoittavat, että yritykset voisivat hyötyä riskien hallintaan ja kaupallistamiseen liittyvien prosessien kehittämisestä. Tutkielma keskittyy biolääkkeiden kaupallistamiseen, erityisesti suomalaisten uusien biolääkeyritysten kannalta. Tutkielma jakaantuu kahteen osaan: ensimmäinen osa tutkii kaupallistamista käsitteenä ja biolääkeliiketoiminnan erityispiirteitä. Toinen osa keskittyy kaupallistamisen empiiriseen tutkimukseen, joka kattaa viisi suomalaista uutta biolääkeyritystä. Empiirisen osan tavoitteena oli tunnistaa ne keinot, jotka auttavat menestyksekkään kaupallistamisprosessin luomisessa tuotekehitysvaiheen läpäisseelle lääkeaineelle. Saavutetut tulokset voidaan tiivistää neljän kriittisen menestystekijän ympärille, jotka ovat 1) tuote, 2) viestintä, 3) uskottavuus ja 4) yhteistyökumppanin valinta. Ensimmäinen menestystekijä on ainutlaatuinen biolääke, joka parantaa kansantaloudellisesti merkittäviä tauteja. Toisen menestystekijän avulla yritys viestittää uudesta ainutlaatuisesta tuotteestaan mahdollisille yhteistyökumppaneilleen. Kolmas menestystekijä kohdistuu yrityksen uskottavuuteen uutena korkean teknologian biolääkeaineiden kehittäjänä. Uskottavuustekijä on erityisen tärkeä suhteiden luomisessa kansainvälisiin lääkeyrityksiin. Neljäs tekijä keskittyy yhteistyökumppanin valintaan, joka alan erityisluonteesta johtuen on tärkeä uudelle biolääkeyritykselle. Viimeiseksi havaittiin, että uusi biolääkeyritys virtuaalisen rakenteensa vuoksi tarvitsee hyvät johdon suhdemarkkinointikyvyt.

Incendiaires et pyromanes [Arson and pyromania, update 2015].

While the fire constitutes a threat and provokes avoidance by the entire animal world, its control as lighting and maintenance is inseparable from the history of humankind. For 1% of the population that use is turned to harm, repeatedly and without objective reason, responding to the historical definition of pyromania. The profile of arsonists does not appear to be different from that of the general criminal population: alcohol abuse, nicotine, marijuana and antisocial personality do not make fire setters a special case. However positive fire experience lived in childhood, emotional avoidance and expertise in fire settings' control seems to be specific, as recidivism risk below that of the general criminal population.

Transgression et initiation : tendances idéologiques et développement littéraire du récit de Genèse 2-3

Several questions about the story of Gen 2-3 remain unresolved in current scholarship. For instance, the implications and manifold consequences of the transgression act - the consumption of the forbidden fruit - are much debated. Interpreters generally agree that the story is connected to several "J" / "non-P" narratives of the primeval history. Besides the use of the tetragrammaton as the designation for God, a common characteristic of these stories is the strong opposition between Yhwh as a harsh deity on one hand and disobedient and transgressing humankind on the other. This paper reconsiders several open questions as well as the aforementioned consensus. The analysis of important motifs in Gen 2-3 leads to the conclusion that this story differs in theologically important ways from the postulated "J"-narrative in Genesis. This indicates that it was not composed as an integral part of that narrative. There are, in Gen 2-3, ideological features and linguistic elements typical of the "J" stratum, but they are all found in the sections that present Yhwh God's investigation and punishment of the couple (3,8-19.24). Since these verses are in tension with or even contradict their immediate context, it should be assigned to a redactional ("J") layer. According to this analysis, the transgression in Gen 2-3 should not be considered a sin. Rather, it is an important step in human evolution towards a self-conscious and autonomous being. The plot has a structure similar to some episodes in ancient Near Eastern myths. 'Initiation' functions as a central theme. Finally, the article discusses the literary milieu of the story. Because of several linguistic and thematic similarities with Gen 1, with P-texts in general, and with the book of Ezekiel, the relationship of Gen 2-3 to these literary entities needs to be reconsidered.

A síntese da amônia: alguns aspectos históricos

A short historical development of discoveries of the nitrogen cycle, the nitrogen sources for agriculture and the ammonia synthesis (in laboratory and industry) are presented. Some brief aspects of nitrogen chemistry are described. Short biographies of Fritz Haber and Carl Bosch, the main persons in this epopee, are also presented.

Da escassez ao estresse do planeta: um século de mudanças no ciclo do nitrogênio

Heavy metals and pesticides are usually associated with the main problems humankind has created in the natural environment. However, compounds with characteristics of essential macronutrients are causing serious environmental changes that could intensify, compromising the diversity of life on the planet. This is the case of nitrogen compounds, produced by industrial processes for use in intensive agriculture in addition to those unwittingly produced from human activities, available in excess in the environment. These compounds warrant greater attention from researchers in various fields of knowledge and public agencies for environmental control, toward minimizing their availability in the environment, thereby returning conditions closer to the natural environmental balance of the planet.

Optimal trading of wind power in the short term market

The energy reform, which is happening all over the world, is caused by the common concern of the future of the humankind in our shared planet. In order to keep the effects of the global warming inside of a certain limit, the use of fossil fuels must be reduced. The marginal costs of the renewable sources, RES are quite high, since they are new technology. In order to induce the implementation of RES to the power grid and lower the marginal costs, subsidies were developed in order to make the use of RES more profitable. From the RES perspective the current market is developed to favor conventional generation, which mainly uses fossil fuels. Intermittent generation, like wind power, is penalized in the electricity market since it is intermittent and thus diffi-cult to control. Therefore, the need of regulation and thus the regulation costs to the producer differ, depending on what kind of generation market participant owns. In this thesis it is studied if there is a way for market participant, who has wind power to use the special characteristics of electricity market Nord Pool and thus reach the gap between conventional generation and the intermittent generation only by placing bids to the market. Thus, an optimal bid is introduced, which purpose is to minimize the regulation costs and thus lower the marginal costs of wind power. In order to make real life simulations in Nord Pool, a wind power forecast model was created. The simulations were done in years 2009 and 2010 by using a real wind power data provided by Hyötytuuli, market data from Nord Pool and wind forecast data provided by Finnish Meteorological Institute. The optimal bid needs probability intervals and therefore the methodology to create probability distributions is introduced in this thesis. In the end of the thesis it is shown that the optimal bidding improves the position of wind power producer in the electricity market.

Energiantuotannossa talteenotetun hiilidioksidin hyötykäyttö

Hiilidioksidilla on merkittävä vaikutus ilmastoon ja suurin osa ihmisten käyttämästä energiasta perustuu hiilipohjaisiin polttoaineisiin. Energiantuotannossa talteenotetun hiilidioksidin hyötykäyttö tarjoaa erinomaisen mahdollisuuden ilmastonmuutoksen vai-kutusten vähentämiseen vaikuttamatta kuitenkaan merkittävästi käytettyihin energialäh-teisiin. CO2:n talteenottotekniikat voidaan jakaa neljään periaatteeltaan erilaiseen tyyppiin: pol-ton jälkeiseen talteenottoon, ennen polttoa tapahtuvaan talteenottoon, happipolttoon ja kemialliseen kiertoon perustuvaan palamiseen. Polton jälkeinen ja ennen polttoa tapah-tuva talteenotto edustavat eniten tutkittua ja käytettyä tekniikkaa. Hyötykäyttökohteita CO2:lla on useita, joista nykyiset merkittävimmät ovat öljyn tuo-tannon tehostus ja elintarviketeollisuus. Tulevaisuudessa merkittäviä käyttökohteita tulee todennäköisesti olemaan uusiutuvan energian varastointi synteettiseen metaa-niin/metanoliin, kemian-, paperi- ja selluteollisuuden prosessit ja vedenkäsittely.

Future at risk: A study on the Club of Rome

Sustainability, in its modern meaning, has been discussed for more than forty years. However, many experts believe that humanity is still far from being sustainable. Some experts have argued that humanity should seek survivable development because it is too late for sustainable one, since 1990s. Obviously, some problems prevented humanity from becoming sustainable. This thesis focuses on the agenda of sustainability discussions and seeks for the essential topics missing from it. For this purpose, the research is conducted on 21 out of 33 books endorsed by the Club of Rome. All of these books are titled ‘a report to the Club of Rome’. The Club of Rome is an organization that has been constantly working on the problems of humankind for the past 40 years. This thesis has three main components: first, the messages of the reports to the Club of Rome, second, academics perceptions of the Club, and third, the Club member perceptions of its evolution, messages and missing topics. This thesis investigates the evolution of four aspects in the reports. The first one is the agenda of the reports. The second one is the basic approaches of the Club (i.e., global, long-term and holistic). The third one is the ways that the reports treat free market and growth ideology. The fourth one is the approach of the reports toward components of the global complex system (i.e., society, economy and politics). The outline of the thesis is as follows. First, the original reports are briefly summarized. After this, the academic perceptions are discussed and structured around three concepts (i.e., futures studies, sustainability and degrowth). In the final step, the perceptions of the experts are collected and analysed, using a variation of Delphi method, called ‘in-depth interviews’, and ‘quality content analysis’ method. This thesis is useful for those interested in sustainability, global problems, and the Club of Rome. This thesis concludes that the reports from 1972 up to 1980 were cohesive in discussing topics related to the problems of humankind. The topics of the reports are fragmented after this period. The basic approaches of CoR are visible in all the reports. However, after 1980, those approaches and especially holistic thinking are only visible in the background. Regarding the free market and growth ideology, although all the reports are against them, the early reports were more explicitly expressing their disagreement. A milestone is noticeable around 1980 when such objections went completely to the background. However, recent reports are more similar to those of 1970s both in adopting a holistic approach and in explicitly criticizing free market and growth ideology. Finally, concerning the components of global complex system, the society is excluded and the focus of the reports is on politics, economy and their relation. Concerning the topics missing from the debate, this thesis concludes that no major research has been conducted on the fundamental and underlying reasons of the problems (e.g. beliefs, values and culture). Studying the problems without considering their underlying reasons, obviously, leads to superficial and ineffective solutions. This might be one of the reasons that sustainability discussions have as yet led to no concrete result.

Climate Change and Ethics of Geoengineering -- Implications Of Climate Emergency Ethics

Global climate change and intentional climate modification, i.e. geoengineering include various ethical problems which are entangled as a complex ensemble of questions regarding the future of the biosphere. The possibilities of catastrophic effects of climate change which are also called “climate emergency” have led to the emergence of the idea of modifying the atmospheric conditions in the form of geoengineering. The novel issue of weather ethics is a subdivision of climate ethics, and it is interested in ethical and political questions surrounding weather and climate control and modification in a restricted spatio-temporal scale. The objective of geoengineering is to counterbalance the adverse effects of climate change and its diverse corollaries in various ways on a large scale. The claim of this dissertation is that there are ethical justifications to claim that currently large-scale interventions to the climate system are ethically questionable. The justification to pursue geoengineering on the basis of considering its pros and cons, is inadequate. Moral judgement can still be elaborated in cases where decisions have to be made urgently and the selection of desirable choices is severely limited. The changes needed to avoid severe negative impacts of climate change requires commitment to mitigation as well as social changes because technical solutions cannot address the issue of climate change altogether. The quantitative emphasis of consumerism should shift to qualitative focus on the aspiration for simplicity in order to a move towards the objective of the continuation of the existence of humankind and a flourishing, vital biosphere.

La connaissance de soi chez Thomas d’Aquin : l’auto-intellection humaine et le moi

Ce mémoire entend présenter les formes de connaissance de soi développées par Thomas d’Aquin: la reditio incompleta, la réfraction sur les phantasmes, la conscience préréflexive, la réflexion par réfluence, l’analyse abstraite, le jugement critique et la reditio completa. L’âme humaine ne pouvant se connaître directement, elle a accès à son essence par le biais de tous ses actes ou actes de conscience. Notre analyse se concentre sur la connaissance habituelle, habitus de toutes les connaissances, qui est la racine de l’image trinitaire en l’homme et garantit la vérité des intellections humaines. Pour ce faire, nous avons procédé à la traduction des questions 87 à 89 de la Somme théologique, dans lesquelles Thomas présente la connaissance humaine des substances séparées et le statut de l’âme séparée, montrant en quoi l’esprit de l’homme partage un certain commun avec les autres esprits de son univers.
