ARTIS: Advanced RTI System
No full textARTIS: Advanced RTI System
The Advanced RTI System (ARTÌS) is a middleware for Parallel and Distributed Simulation (PADS) supporting massively populated models. The middleware provides to system modellers an easy-to-use software tool in which is possible to build simulation models that can be executed using a sequential (monolithic) or parallel/distributed approach. On top of ARTIS, the Generic Adaptive Interaction Architecture (GAIA) framework provides an environment in which the simulation entities are adaptively clustered based on their communication patterns. The aim of this mechanism is to reduce the communication overhead of the PADS and to improve the Load Balancing of the execution architecture. In practice, GAIA offers to the final user a clear and elegant paradigm for the implementation of simulation models.
The software, that is free for educational and research purposes, can be downloaded from the research group website: http://pads.cs.unibo.it
on the same website is possibile to find some documentation on the usage of the sofware and the FAQs.

The last version of ARTIS (version 2.0.0) integrates both the middleware, the GAIA framework, many simulation models and all the necessary scripts and tools for the evaluation of complex systems. The most part of this software is provided in both binary and source code versions.
The ARTIS/GAIA software has been described/used in the following research papers (PARTIAL LIST):

No full textHypercoagulability during l‐asparaginase treatment: the effect of antithrombin III supplementation in vivo
No full textTo evaluate the occurrence of hypercoagulability during treatment with l‐asparaginase (l‐ase), thrombin‐antithrombin complex (TAT) and d‐dimer levels in plasma were serially measured in 15 consecutive adult patients with acute lymphoblastic leukaemia or lymphoblastic lymphoma who had recently completed a chemotherapy cycle with cytosine arabinoside and methotrexate. The first eight patients (group A) received i.v. l‐ase alone (20000 U/m2 on alternate days over 10 d); the last seven patients (group B) received, in addition to l‐ase, bolus injection of antithrombin concentrate (2000 U) on alternate days for a total of six administrations, beginning with the second l‐ase infusion. Increased levels of TAT (P<0·05) and d‐dimer (P<0·01) were observed prior to l‐ase, possibly related to inflammation and cytolysis secondary to previous chemotherapy. In patients treated with l‐ase alone, further elevation of TAT (P<0·05) and persistence of increased d‐dimer were observed, associated with marked reduction of the anticoagulant activities of protein C, protein S and antithrombin III. At variance, in patients receiving antithrombin III supplementation there was no increase of TAT and a normalization of d‐dimer levels occurred during l‐ase treatment. In these patients, mean plasma antithrombin III activity was maintained at levels higher than 70% of normal throughout the treatment. The rate of decline of fibrinogen, factor IX, protein C and protein S was unaffected by antithrombin III supplementation, indicating that hypercoagulability has little if any relevance for the reduction of coagulation factors and inhibitors induced by l‐ase treatment. The usefulness of antithrombin III concentrates in preventing thromboembolic complications in patients submitted to l‐ase treatment remains to be determined. Copyright © 1990, Wiley Blackwell.

Capitalismo e risorse minerarie in una prospettiva ‘sferica’”
No full textCome è cambiata la nostra percezione dell’ambiente da quando le prime navicelle spaziali ci hanno mostrato le immagini di un piccolo globo, di dimensioni finite, le cui risorse - per quanto estese possano essere - sono a loro volta finite? E’ quanto si domandava intorno alla metà degli anni Sessanta Kenneth Boulding, secondo cui le prime fotografie della Terra scattate dallo spazio contribuirono a mettere definitivamente in crisi l’illusione di vivere in un mondo virtualmente illimitato, senza frontiere - un mondo dove le risorse ambientali sono infinitamente a disposizione degli uomini che non hanno bisogno di preoccuparsi della loro disponibilità futura e degli effetti inquinanti derivati dal loro sfruttamento (Boulding 1966). L’obiettivo di una crescita economica continua, ricercata ossessivamente da tutti i governi fin dalla fine della Seconda guerra mondiale (Kula 1998), e avvalorata dalle analisi degli economisti neoclassici, veniva perciò messo seriamente in discussione: uno sviluppo senza limiti poteva essere davvero desiderabile considerati i possibili disastrosi esiti in termini di inquinamento, guerre per l’accaparramento delle risorse e povertà?
Con queste domande in mente, l’obiettivo primario di questo capitolo è passare in rassegna alcuni studi antropologici focalizzati sulla questione dello sfruttamento delle risorse e, in particolare, di quelle minerarie. Il filo conduttore di questa riflessione è l’immagine stessa del nostro globo terrestre

Negare l’ovvietà. Identità, violenza e razzismo attraverso il discorso antropologico
No full textC’è una nozione in antropologia che segnala, forse meglio di altre, alcuni aspetti dell’irrisolto rapporto di questa disciplina tra formulazioni teoriche, pratica etnografica e responsabilità dell’antropologo fuori dal e nel campo. Questa è la nozione di “razza”. A partire dagli anni Settanta gli antropologi sentivano di aver fatto abbastanza per combattere il razzismo e fronteggiare le discriminazioni razziali. Oggi che il razzismo continua a persistere e a trovare nuove forme e nuove retoriche per radicarsi in pratiche e discorsi del quotidiano, il sapere antropologico - che pure ha effettivamente giocato un ruolo importante in molte battaglie civili per i diritti umani - sembra avere poco da dire a proposito del razzismo. La domanda che ci poniamo qui senza pretendere di trovare una risposta conclusiva è perché. Perché ci sono nozioni antropologiche che si prestano ad un “cattivo uso”? Ovvero, il problema è solo nell’uso

Il duro lavoro ed i soldi veloci. L’economia occulta dell’estrazione mineraria in Sierra Leone”
No full textQuesto contributo ha l’obiettivo teorico, e al contempo critico, di mettere in luce il carattere ideologico dei miti e delle superstizioni che sorreggono l’economia simbolica della nostra società facendo quel “giro più lungo” che contraddistingue un certo modo – ma non l’unico - di fare l’antropologia: andare lontano per capire qualcosa di più di ciò che ci è vicino e familiare riflettendo criticamente sui nostri stessi modi di vita. Parafrasando un autore di cui avremo modo di riparlare a breve, lo scopo di questa analisi è di evidenziare come l’interpretazione di certe reazioni magiche e fantastiche alla nostra realtà non fantastica, possa essere parte di una critica metaforica ed obliqua dei moderni modi di sfruttamento e di produzione dell’economia capitalista
Dimenticare i propri morti. Oggetti alienabili ed inalienabili nel Nord Ovest della Tanzania
No full textChanging environments, occult protests, and social memories in Sierra Leone
No full textIn Sierra Leone, the environmental and economic impacts of extractive industry are a source of great concern for local communities. Through the usual weapons of the weak (e.g., sabotage, thefts, and rumors) and the idiom of the occult, the population expresses dissatisfaction with a modernity which has always been promised but never achieved. By comparing three different cases this paper argues that extractive landscapes are places of great political contest at the local and national level. In the first and the second case I will explore the ways in which the inhabitants of two different mining regions interpret in terms of the occult some unexpected and mysterious events occurring to a large-scale mining company and to a hydroelectric power dam. In the third case I will show how the complex interplay of negotiations between diamond miners and inhabitants of mining areas can be mediated by the presence of spiritual beings locally named 'debul dem'. What I suggest is that mining or extractive landscapes are never neutral sites. They embody past experiences which simultaneously globally connect and locally disconnect places and people. From an anthropological perspective, occult mining narratives can be analyzed as forms of social memory pointing to a history of violence, terror, and uncertainties inscribed in the landscape and dwelling practices. The basic idea of this paper is that the local discourses on the occult are not just ways to make sense of the uncertainties and anxieties of a globalized modernity but are, above all, highly politicized practice
