Quelle est la différence entre un flibustier et un pirate ? Ce projet de recherche est basé sur cette question enfantine. En fait, les historiens contemporains, qui ont consacré de nombreuses pages à la « piraterie » et à la « flibuste » de l’âge moderne, n’ont pas réussi à répondre à cette – apparemment – simple question. Les reconstructions et les théories développées, en fait, ont assimilé ces deux phénomènes, en traitant les deux termes comme de simples synonymes. Mais, si cela peut être considéré comme vrai aujourd’hui, il n'était pas au cours des XVIIème et XVIIIème siècles. À l'époque, pirate était équivalent de « hostis humani generis », et comme tel craint et persécuté. Les flibustiers, au contraire, ont été considérés comme l’un des groupes les plus importants dans les premiers établissements des îles de la Mer des Caraïbes. En outre, le terme flibustier, dans la correspondance des gouverneurs français, se réfère à un élément considéré comme essentiel pour la réussite du processus de construction de la colonie, et également cruciale pour la consolidation des établissements américains. C’est donc la relation spéciale entre les flibustiers et le Nouveau Monde est l’objet de cette thèse. En utilisant une approche historico-culturel, on a essayé de contextualiser le phénomène de la flibuste dans le « processus d’américanisation » des premières communautés européennes en Amérique. La relation étroite entre les colons des établissements français de Saint-Domingue (aujourd’hui Haïti) et les nombreux espaces - économique, militaire, diplomatique, social, humain - des Caraïbes a fait des flibustiers un élément fortement « américanisé ». Grâce à la lecture des documents d'archives et les mémoires des années entre 1684 et 1727, on a reconstruit la dynamique de la relation entre ce groupe et le contexte américain, avec une attention particulière à la dynamique culturelle et sociale.

Joaquín Camaño fu un gesuita della Provincia del Paraguay, vissuto nell' esilio italiano la maggior parte della sua vita dal 1767 al 1820. Il suo lavoro e la sua fama possono essere considerati di minore importanza se paragonati a molti altri gesuiti esiliati per ordine di Carlo III alla fine del XVIII secolo in Emilia-Romagna. Attraverso la mia ricerca approfondisco il ruolo di J. Camaño quale personaggio minore che entra nella vita degli altri espulsi tramite un dinamico network relazionale di cui è stato uno dei principali artefici. Il mio obiettivo è stato quello di studiare l'impatto che ebbero gli esuli gesuiti americani, attraverso la vita di Joaquin Camaño, sul mondo intellettuale italiano, europeo ed americano dopo l'espulsione del 1767. Egli, con i suoi studi, si inserisce nella rinnovata e vivace retorica del “Mondo Nuovo” che in quegli anni assume un grande dinamismo. Nato nella modesta città di La Rioja, in Argentina, si erge come un brillante cartografo, etnografo e linguista nel contesto dell'Illustrazione europea grazie alla sua particolare vita da missionario. Dopo l'espulsione, Joaquin Camaño, insieme ad altri numerosi confratelli americani, arriverà a Faenza, nello Stato Pontificio, dedicandosi allo studio della cartografia, dell'etnografia e delle lingue americane. Le sue ricerche si collocano in un momento nevralgico per la storia del pensiero linguistico-antropologico, quando l'osservazione diretta e la riflessione teorica dei fenomeni si misuravano con la grande varietà umana ormai riscontrata nel mondo.

Con le "Imagini degli dei degli antichi", pubblicate a Venezia nel 1556 e poi in più edizioni arricchite e illustrate, l’impegnato gentiluomo estense Vincenzo Cartari realizza il primo, fortunatissimo manuale mitografico italiano in lingua volgare, diffuso e tradotto in tutta l’Europa moderna. Cartari rimodula, secondo accenti divulgativi ma fedeli, fonti latine tradizionali: come le ricche "Genealogie deorum gentilium" di Giovanni Boccaccio, l’appena precedente "De deis gentium varia et multiplex historia" di Lilio Gregorio Giraldi, i curiosi "Fasti" ovidiani, da lui stesso commentati e tradotti. Soprattutto, però, introduce il patrimonio millenario di favole ed esegesi classiche, di aperture egiziane, mediorientali, sassoni, a una chiave di lettura inedita, agile e vitalissima: l’ecfrasi. Le divinità e i loro cortei di creature minori, aneddoti leggendari e attributi identificativi si susseguono secondo un taglio iconico e selettivo. Sfilano, in trionfi intrisi di raffinato petrarchismo neoplatonico e di emblematica picta poesis rinascimentale, soltanto gli aspetti figurabili e distintivi dei personaggi mitici: perché siano «raccontate interamente» tutte le cose attinenti alle figure antiche, «con le imagini quasi di tutti i dei, e le ragioni perché fossero così dipinti». Così, le "Imagini" incontrano il favore di lettori colti e cortigiani eleganti, di pittori e ceramisti, di poeti e artigiani. Allestiscono una sorta di «manuale d’uso» pronto all’inchiostro del poeta o al pennello dell’artista, una suggestiva raccolta di «libretti figurativi» ripresi tanto dalla maniera di Paolo Veronese o di Giorgio Vasari, quanto dal classicismo dei Carracci e di Nicolas Poussin. Si rivelano, infine, summa erudita capace di attirare appunti e revisioni: l’antiquario padovano Lorenzo Pignoria, nel 1615 e di nuovo nel 1626, vi aggiunge appendici archeologiche e comparatistiche, interessate al remoto regno dei faraoni quanto agli esotici idoli orientali e dei Nuovi Mondi.

Capuchin monkeys are notable among New World monkeys for their widespread use of tools. They use both hammer tools and insertion tools in the wild to acquire food that would be unobtainable otherwise. Evidence indicates that capuchins transport stones to anvil sites and use the most functionally efficient stones to crack nuts. We investigated capuchins’ assessment of functionality by testing their ability to select a tool that was appropriate for two different tool-use tasks: A stone for a hammer task and a stick for an insertion task. To select the appropriate tools, the monkeys investigated a baited tool-use apparatus (insertion or hammer), traveled to a location in their enclosure where they could no longer see the apparatus, made a selection between two tools (stick or stone), and then could transport the tool back to the apparatus to obtain a walnut. Four capuchins were first trained to select and use the appropriate tool for each apparatus. After training, they were then tested by allowing them to view a baited apparatus and then travel to a location 8 m distant where they could select a tool while out of view of the apparatus. All four monkeys chose the correct tool significantly more than expected and transported the tools back to the apparatus. Results confirm capuchins’ propensity for transporting tools, demonstrate their capacity to select the functionally appropriate tool for two different tool-use tasks, and indicate that they can retain the memory of the correct choice during a travel time of several seconds.

Self-control is a prerequisite for complex cognitive processes such as cooperation and planning. As such, comparative studies of self-control may help elucidate the evolutionary origin of these capacities. A variety of methods have been developed to test for self-control in non-human primates that include some variation of foregoing an immediate reward in order to gain a more favorable reward. We used a token exchange paradigm to test for self-control in capuchin monkeys (Cebus apella). Animals were trained that particular tokens could be exchanged for food items worth different values. To test for self-control, a monkey was provided with a token that was associated with a lower-value food. When the monkey exchanged the token, the experimenter provided the monkey with a choice between the lower-value food item associated with the token or another token that was associated with a higher-value food. If the monkey chose the token, they could then exchange it for the higher-value food. Of seven monkeys trained to exchange tokens, five demonstrated that they attributed value to the tokens by differentially selecting tokens for higher-value foods over tokens for lower-value foods. When provided with a choice between a food item or a token for a higher-value food, two monkeys selected the token significantly more than expected by chance. The ability of capuchin monkeys to forego an immediate food reward and select a token that could then be traded for a more preferred food demonstrated some degree of self-control. Thus, results suggest a token exchange paradigm could be a successful technique for assessing self-control in this New World species.

The benefits animals derive from living in social groups have produced the evolution of many forms of cooperative behavior. To cooperate, two or more individuals coordinate their actions to accomplish a common goal. One cognitive process that has the potential to influence cooperation is self control. Individuals delaying their impulsive choice for an immediate reward may potentially receive a larger reward later by cooperating with others. In this study, I measured whether brown capuchin monkeys (Cebus apella) were capable of impulse control and whether impulse control was related to cooperation. Impulse control and cooperation were measured using a lazy susan-like apparatus, on which animals could turn a wheel to receive food rewards. The capuchins went through two training phases that taught them how to turn the wheel efficiently to obtain rewards and how to turn the wheel to obtain the larger of two rewards. After training, I tested impulse control by giving the capuchins a choice between a smaller and a larger reward placed at shorter or more distant locations on the wheel. The capuchins demonstrated impulse control in that they tended to inhibit the impulse to select the smaller reward when it was closer and easier to reach and instead selected the larger reward when it was farther away. Cooperation was tested in all possible dyads of seven individuals, a total of 21 dyads, by allowing each dyad 10 trials to work together with effort on the lazy-susan so that each would obtain a reward. Seventeen out of 21 dyads cooperated by simultaneously moving the wheel in the same direction. The correlation between how often a particular dyad cooperated and their average impulse control score was not statistically significant, r(21) = -.125, p = .591. Capuchins demonstrated impulse control and cooperation using this novel apparatus but the two abilities were not related. Other factors such as the unique social relationship between two individuals may play a more prominent role in the motivation to cooperate rather than the cognitive capacity to inhibit behavior.

The present case report describes a novel etiological agent of cutaneous leishmaniasis that appears for the first time in a cow. A similar agent had recently been described as causing autochthonous infections in horses of Germany and Switzerland. The infection in the cow was initially diagnosed upon clinical and immunohistological findings. Subsequent comparative sequence analysis of diagnostic PCR products from the internal transcribed spacer 1 (ITS1) of ssrRNA classified the respective isolate as neither Old World nor New World Leishmania species, but yielded complete identity of the analysed sequence with the above mentioned horse cases and 98% identity to Leishmania sp. siamensis, an organism recently identified in a visceral leishmaniasis patient from Thailand. The potential transmitting vectors for all these cases have not yet been identified. Future investigations will have to elucidate the veterinary-epidemiological relevance of this etiological agent, as well as biological parameters such as transmission mode and geographical origin and distribution.

Self-control allows an individual to obtain a more preferred outcome by forgoing an immediate interest. Self-control is an advanced cognitive process because it involves the ability to weigh the costs and benefits of impulsive versus restrained behavior, determine the consequences of such behavior, and make decisions based on the most advantageous course of action. Self-control has been thoroughly explored in Old World primates, but less so in New World monkeys. There are many ways to test self-control abilities in non-human primates, including exchange tasks in which an animal must forgo an immediate, less preferred reward to receive a delayed, more preferred reward. I examined the self-control abilities of six capuchin monkeys using a task in which a monkey was given a less preferred food and was required to wait a delay interval to trade the fully intact less preferred food for a qualitatively higher, more preferred food. Partially eaten pieces of the less preferred food were not rewarded, and delay intervals increased on an individual basis based on performance. All six monkeys were successful in inhibiting impulsivity and trading a less preferred food for a more preferred food at the end of a delay interval. The maximum duration each subject postponed gratification instead of responding impulsively was considered their delay tolerance. This study was the first to show that monkeys could inhibit impulsivity in a delay of gratification food exchange task in which the immediate and delayed food options differed qualitatively and a partially eaten less preferred food was not rewarded with the more preferred food at the end of a delay interval. These results show that New World monkeys possess advanced cognitive abilities similar to those of Old World primates.

Recent publishing on the migration phenomena in the communitarian and globalized Europe, puts in evidence a fundamental racism which is capable of making cultural processes grow and feed both chaos and social disorder. As a matter of fact we are approaching the ending debates on multicultural citizenship as well as on solidary integration and antiracism. Since the appearing of these phenomena, namely the huge post colonial migration in the nineteen-eighties, by which the colonized countries became almost “emigrant nurseries”, one could expect their stabilization. On the contrary, globalization and migration (twin subjects) everywhere still produce, at various levels, social disturbances together with some chauvinistic limitations as an ultimate kind of western prosperity defense. The peculiar European features of this new racism, less than ideological (superiority, homogeneity and civilizing mission), are confined to the concepts of patriotism, inequality and exclusion. In these terms one can understand why the new economic expansionism and the quest for new world markets makes European policies unstable, which remain undecided between conservatism, liberalism and extreme right. All this explains at least two things: the existing ambiguities of some European policies aiming to enhance particular forms of protectionism, and the difficulties in which the antiracist thought seems to be embedded. Indeed, according to what Walter Lorenz has already made clear, by using a well founded methodology, which prevents any fruitless protestations, it is impossible to contrast racism and nationalism. In such context, the educational field should try to use an operative epistemology. In other words the antiracist thought should dispose of competences and skills and, especially, personal and reflective capabilities. All this in order to avoid that which, in different historical scenes, permit the revival of the sense of moral opprobrium could not be identified with the political alibi to maintain privileges as well as advantages for the exclusive benefit of wealthy countries.

While sound and video may capture viewers' attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution is this new type of interactive content, offered in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop multimedia authoring package Macromedia Director into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals. The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper. In the following sections, an overview of the operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services. The next section examines a number of metadata languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services.

The emergence of the diary as a digital form has generated the kinds of introduction and explanation that typically accumulate around emerging genres, even though online diarists in many ways strive to reproduce the stereotypical print diary. However, as diarists and readers explore the nature of blogs, both in diary entries and comments pages, a tension is apparent between users’ accounts or explanations of the genre and their actual practices, and this tension provides a rich site for studying the evolution of the diary genre. Readers’ and writers’ comments illustrate the blogging community’s ideas about genre as a concept and how these ideas transfer to the “new” world of online media. In this paper, I look at the diary’s transition from page to screen, and consider how readers and writers build on and diverge from print culture practices in establishing expectations and “rules” for Weblogs. Examining how diarists and their communities establish and police the digital diary, and how generic knowledge is circulated and codified, helps understand the particular social actions the diary can perform only on the Internet.

The present report describes a novel etiological agent of cutaneous leishmaniasis in horses that, at least for some cases, sporadically appeared as autochthonous infections in geographically distant regions of Germany and Switzerland. The infection was initially diagnosed upon clinical and immunohistological findings. Subsequent comparative sequence analysis of diagnostic PCR products from the internal transcribed spacer 1 (ITS1) of ssrRNA classified the respective isolates as neither Old World nor New World Leishmania species. However, four isolates subjected to molecular analyses all exhibited a close phylogenetic relationship to Leishmania sp. siamensis, an organism recently identified in a visceral leishmaniasis patient from Thailand. Future investigations will demonstrate if this form of leishmaniasis represents an emerging, and perhaps zoonotic, disease of European, or even global, importance.

Since the UsedSoft ruling of the CJEU in 2012, there has been the distinct feeling that – like the big bang - UsedSoft signals the start of a new beginning. As we enter this brave new world, the Copyright Directive will be read anew: misalignments in the treatment of physical and digital content will be resolved; accessibility and affordability for consumers will be heightened; and lock-in will be reduced as e-exhaustion takes hold. With UsedSoft as a precedent, the Court can do nothing but keep expanding its own ruling. For big bang theorists, it is only a matter of time until the digital first sale meteor strikes non-software downloads also. This paper looks at whether the UsedSoft ruling could indeed be the beginning of a wider doctrine of e-exhaustion, or if it is simply a one-shot comet restrained by provisions of the Computer Program Directive on which it was based. Fighting the latter corner, we have the strict word of the law; in the UsedSoft ruling, the Court appears to willingly bypass the international legal framework of the WCT. As far as expansion goes, the Copyright Directive was conceived specifically to implement the WCT, thus the legislative intent is clear. The Court would not, surely, invoke its modicum of creativity there also... With perhaps undue haste in a digital market of many unknowns, it seems this might well be the case. Provoking the big bang theory of e-exhaustion, the UsedSoft ruling can be read as distinctly purposive, but rather than having copyright norms in mind, the standard for the Court is the same free movement rules that underpin the exhaustion doctrine in the physical world. With an endowed sense of principled equivalence, the Court clearly wishes the tangible and intangible rules to be aligned. Against the backdrop of the European internal market, perhaps few legislative instruments would staunchly stand in its way. With firm objectives in mind, the UsedSoft ruling could be a rather disruptive meteor indeed.
