La critica d'arte di Alberto Arbasino. Percorsi di un flâneur atipico fra impegno culturale e sperimentalismo formale.

La critica d’arte di Alberto Arbasino è al momento ancora poco discussa dalla critica letteraria che, in taluni casi, si è limitata a indicarne sommariamente i retaggi longhiani. La nostra ricerca, pur partendo dai medesimi presupposti, ha poi spinto verso altre direzioni, poiché la lettura dei materiali in primo luogo ci ha posto dinanzi a un quesito, ossia quanto questi rientrino per peculiarità e scelte stilistiche nella categoria della scrittura artistica, e in secondo luogo ci ha permesso di appurare quanto la funzione di operatore culturale, tanto cara all'autore, pungoli l’interessamento verso questo campo d’indagine e quanto lo renda un prodotto di Alta Cultura. Questi, quindi, gli aspetti che assurgono come materia precipua di studio: analisi stilistica e impegno culturale

Algunas reflexiones sobre crecidas e inundaciones

El presente trabajo pretende brindar un panorama global sobre distintos temas asociados con la ocurrencia de desastres debidos a crecidas e inundaciones y analizar las implicancias desde los puntos de vista hidrológicos, hidráulicos, de ingeniería y de planificación, que deben ser considerados de forma integrada y transdisciplinaria a efectos de reducir las pérdidas en vidas humanas y los crecientes efectos negativos económicos. Se discute la importancia relativa de las consecuencias de desastres por crecidas en sociedades de diferentes niveles de desarrollo, comparándose además brevemente sus efectos con otros fenómenos naturales de escala relevante. Se hace especial mención al sistema de alerta de la cuenca del Plata, de 3.150.000 km2, en territorios de Bolivia, Paraguay, Brasil, Uruguay y Argentina, afectada por las crecidas de los ríos Paraná, Paraguay, Uruguay, Iguazú, Pilcomayo y Bermejo. En tal sentido, se comentan las crecidas del río Paraná y la evolución del sistema de alerta, describiendo los modelos utilizados para la predicción de caudales. Se concluye con una opinión técnica acerca de los temas de investigación y desarrollo que deberían ser considerados prioritariamente por parte de los investigadores, en virtud de su particular importancia para el control de crecidas

Bio-inspired Mechanisms for Artificial Self-organised Systems

Research on self-organization tries to describe and explain forms, complex patterns and behaviours that arise from a collection of entities without an external organizer. As researchers in artificial systems, our aim is not to mimic self-organizing phenomena arising in Nature, but to understand and to control underlying mechanisms allowing desired emergence of forms, complex patterns and behaviours. In this paper we analyze three forms of self-organization: stigmergy, reinforcement mechanisms and cooperation. For each forms of self-organisation, we present a case study to show how we transposed it to some artificial systems and then analyse the strengths and weaknesses of such an approach

Série concertos da "Confraria de La Yerba"

Anais do 35º Seminário de Extensão Universitária da Região Sul - Área temática: CulturaEste projeto possibilita, além da integração dos alunos em diversos espaços de aprendizagem musical e outros espaços culturais, a articulação com diversos contextos sócio-educativos, objetivando divulgar a música platina e, com isto, a música cantada em língua espanhola; os instrumentos autóctones da região e os diversos modos de compor e interpretar a(s) música(s). Tem-se como objetivo desenvolver a ação pedagógica, adotando postura interdisciplinar e de trabalho em equipe, construindo competências e saberes educacionais; além de colaborar com a formação musical dos alunos de graduação da Unipampa participando em um grupo que estimula a prática musical em conjunto. A metodologia adotada neste projeto é de caráter interdisciplinar, articulando os saberes e fazeres construídos desde as práticas realizadas em componentes curriculares da Licenciatura em Música e em outros espaços de aprendizagem, contemplando as experiências prévias dos integrantes do grupo articuladas com as novas vivências e saberes. As avaliações dos eventos realizados e autoavaliações de cada integrante contribuem para o desenvolvimento do grupo em geral, de suas ações didático-musicais, comunitárias e performáticas, colaborando para o crescimento pessoal e grupal. Espera-se contribuir, com este projeto, para a ampliação de espaços diversificados de divulgação da música regional, platina e latino-americana atingindo os mais diversos públicos, desde uma perspectiva didático-musical e socia

Long-term effects of intermittent IL-2 in HIV infection: extended follow-up of the INSIGHT STALWART Study

BACKGROUND The Study of Aldesleukin with and without Antiretroviral Therapy (STALWART) was designed to evaluate whether intermittent IL-2 alone or with peri-cycle ART increased CD4+ cell counts (and so delayed initiation of ART) in HIV infected individuals having ≥ 300 CD4+ cells/mm(3) compared to untreated controls. When the results of two large clinical trials, ESPRIT and SILCAAT, showed no clinical benefit from IL-2 therapy, IL-2 administration was halted in STALWART. Because IL-2 recipients in STALWART experienced a greater number of opportunistic disease (OD) or death and adverse events (AEs), participants were asked to consent to an extended follow-up phase in order to assess persistence of IL-2 effects. METHODOLOGY Participants in this study were followed for clinical events and AEs every 4 months for 24 months. Unadjusted Cox proportional hazards models were used to summarize death, death or first OD event, and first grade 3 or 4 AE. PRINCIPAL FINDINGS A total of 267 persons were enrolled in STALWART (176 randomized to the IL-2 arms and 91 to the no therapy arm); 142 individuals in the IL-2 group and 80 controls agreed to enter the extended follow-up study. Initiation of continuous ART was delayed in the IL-2 groups, but once started, resulted in similar CD4+ cell and viral load responses compared to controls. The hazard ratios (95% CI) for IL-2 versus control during the extension phase for death or OD, grade 3 or 4 AE, and grade 4 AE were 1.45 (0.38, 5.45), 0.43 (0.24, 1.63) and 0.20 (0.04, 1.03), respectively. The hazard ratios for the AE outcomes were significantly lower during the extension than during the main study. CONCLUSIONS Adverse events associated with IL-2 cycling did not persist upon discontinuation of IL-2. The use of IL-2 did not impact the subsequent response to initiation of cART

A Negotiation Style Recommender Based on Computational Ecology in Open Negotiation Environments

The system described herein represents the first example of a recommender system in digital ecosystems where agents negotiate services on behalf of small companies. The small companies compete not only with price or quality, but with a wider service-by-service composition by subcontracting with other companies. The final result of these offerings depends on negotiations at the scale of millions of small companies. This scale requires new platforms for supporting digital business ecosystems, as well as related services like open-id, trust management, monitors and recommenders. This is done in the Open Negotiation Environment (ONE), which is an open-source platform that allows agents, on behalf of small companies, to negotiate and use the ecosystem services, and enables the development of new agent technologies. The methods and tools of cyber engineering are necessary to build up Open Negotiation Environments that are stable, a basic condition for predictable business and reliable business environments. Aiming to build stable digital business ecosystems by means of improved collective intelligence, we introduce a model of negotiation style dynamics from the point of view of computational ecology. This model inspires an ecosystem monitor as well as a novel negotiation style recommender. The ecosystem monitor provides hints to the negotiation style recommender to achieve greater stability of an open negotiation environment in a digital business ecosystem. The greater stability provides the small companies with higher predictability, and therefore better business results. The negotiation style recommender is implemented with a simulated annealing algorithm at a constant temperature, and its impact is shown by applying it to a real case of an open negotiation environment populated by Italian companie
