Pensar su tiempo, deshilvanar el orden social

Edgardo Antonio Vigo fue un artista plástico que utilizó distintas técnicas y formas de expresión, como la poesía visual, las performances urbanas, el arte correo, la escritura de manifiestos y otros textos, así como la edición de revistas, entre otras actividades. Vigo produjo su poética en clave de rebeldía de su tiempo, especialmente entre los '60 y '70, pero su rebelión transcurrió también por fuera del estereotipo más consolidado para la época. La obra de Vigo retoma algunos procedimientos de las vanguardias, como la utilización del objeto ya hecho, el uso de espacios alternativos de producción y difusión de sus obras, el abandono casi completo del formato de cuadro, entre otros. Interesa pensar en este trabajo de qué modo esta apropiación de técnicas y procedimientos previos, se combina con otra ruptura dirigida no sólo al sistema artístico, sino también al orden social. En este sentido, la obra de Vigo piensa su tiempo. ;Así como tematizó ciertos acontecimientos de relevancia política de los ámbitos nacional e internacional, también realizó una operación novedosa en su obra: la utilización del discurso judicial-administrativo. Se analizan en este trabajo algunos de sus usos en acciones artísticas. Concluimos en que se trató de una materia que incorporaría en su poética para desnaturalizarla de su lugar original, aristocrático y privatista. En este sentido, toma un aspecto no menor del funcionamiento del orden social disociándolo de su lugar normal y, al ofrecerlo a todos a través de acciones artísticas, permite una apropiación descentrada, fuera de los límites impuestos por su naturaleza

Events in Indonesia: exploring the limits to formal tourism trends forecasting methods in complex crisis situations

The desire to know the future is as old as humanity. For the tourism industry the demand for accurate foretelling of the future course of events is a task that consumes considerable energy and is of great significance to investors. This paper examines the issue of forecasting by comparing forecasts of inbound tourism made prior to the political and economic crises that engulfed Indonesia from 1997 onwards with actual arrival figures. The paper finds that current methods of forecasting are not able to cope with unexpected crises and other disasters and that alternative methods need to be examined including scenarios, political risk and application of chaos theory. The paper outlines a framework for classifying shocks according to a scale of severity, probability, type of event, level of certainty and suggested forecasting tools for each scale of shock.

Fatty acids as haptens: exploring the limits of antigenicity

Fatty acids (FAs) are relatively small, hydrophobic and highly mobile molecular structures with vital biological functions and a ubiquitous distribution. Surprisingly, however, they can be rendered immunogenic. We have synthesised a novel immunogen in which dicarboxylic linoleic acid was conjugated to a carrier protein. Dicarboxylic fatty acids (DCA) differ from their normal counterparts only by their possession of a carboxyl group at each end of the molecule. When conjugated to proteins as haptens, they are, therefore, presented to the immune system with a free carboxyl group at the distal end, instead of a methyl group. Polyclonal IgG antibodies raised in response to this unique immunogen could bind not only conjugated hapten with high affinity, but also the equivalent free FA in mono and dicarboxylic form. Similar conjugates constructed from normal FAs produced much weaker antibody responses and could scarcely be considered antigenic at all. The cross-reactivities of the anti-DCA antibodies with FA variants differing in the number, position and configuration of their double bonds showed that the antibody paratope (binding site) was structured to accommodate the hapten in a way that depended on the precise shape of the acyl chain. We suggest that FAs become much more effective as B-cell epitopes when presented with their hydrophilic carboxyl group exposed on the surface of immunogenic conjugates. This type of epitope is determined by the particular double bond pattern of the unsaturated acyl chain, as well as the polar head group. (C) 2003 Elsevier Ltd. All rights reserved.

An evolutionary radiation of beeflies in semi-arid Australia: systematics of the Exoprosopini (Diptera : Bombyliidae)

Almost half of the 4822 described beeflies in the world belong to the subfamily Anthracinae, with most of the diversity found in three cosmopolitan tribes: Villini, Anthracini, and Exoprosopini. The Australian Exoprosopini previously contained three genera, Ligyra Newman, Pseudopenthes Roberts and Exoprosopa Macquart. Pseudopenthes is an Australian endemic, with two species including Ps. hesperis, sp. nov. from Western Australia. Two new species of the exoprosopine Atrichochira Hesse, Atr. commoni, sp. nov. and Atr. paramonovi, sp. nov., are also described from Australia, extending the generic distribution from Africa. Cladistic analysis clarified the phylogenetic relationships between the recognised groups of the Exoprosopini and determined generic limits on a world scale. Inclusion of 18 Australian exoprosopines placed the Australian species in the context of the world fauna. The Exoprosopini contains six large groups. The basal group I contains species previously included in Exoprosopa to which the name Defilippia Lioy is applied. Group II contains Heteralonia Rondani, Atrichochira, Micomitra Bowden, Pseudopenthes, and Diatropomma Bowden. Colossoptera Hull is newly synonymised with Heteralonia. Group III is a paraphyletic assemblage of Pterobates Bezzi and Exoprosopa including the Australian Ex. sylvana ( Fabricius). Ligyra is paraphyletic, forming two well-separated clades. The African clade is described as Euligyra Lambkin, gen. nov., which, together with Litorhina Bezzi and Hyperalonia Rondani, form group IV. The Australian group V is true Ligyra. The remaining monophyletic lineage of exoprosopines, group VI, the Balaana-group of genera, shows evidence of an evolutionary radiation of beeflies in semi-arid Australia. Phylogenetic analysis of all 42 species of the Balaana-group of genera formed a basis for delimiting genera. Seven new genera are described by Lambkin & Yeates: Balaana, Kapua, Larrpana, Munjua, Muwarna, Palirika and Wurda. Four non-Australian species belong to Balaana. Thirty two new Australian species are described: Bal. abscondita, Bal. bicuspis, Bal. centrosa, Bal. gigantea, Bal. kingcascadensis, K. corusca, K. irwini, K. westralica, Lar. collessi, Lar. zwicki, Mun. erugata, Mun. lepidokingi, Mun. paralutea, Mun. trigona, Muw. vitreilinearis, Pa. anaxios, Pa. basilikos, Pa. blackdownensis, Pa. bouchardi, Pa. cyanea, Pa. danielsi, Pa. decora, Pa. viridula, Pa. whyalla, W. emu, W. impatientis, W. montebelloensis, W. norrisi, W. patrellia, W. skevingtoni, W. windorah, and W. wyperfeldensis. The following new combinations are proposed: from Colossoptera: Heteralonia latipennis (Brunetti); from Exoprosopa: Bal. grandis (Pallas), Bal. efflatounbeyi (Paramonov), Bal. latelimbata ( Bigot), Bal. obliquebifasciata ( Macquart), Bal. tamerlan (Portschinsky), Bal. onusta ( Walker), Def. busiris (Jaennicke), Def. efflatouni ( Bezzi), Def. eritreae (Greathead), Def. gentilis ( Bezzi), Def. luteicosta ( Bezzi), Def. minos (Meigen), Def. nigrifimbriata ( Hesse), Def. rubescens ( Bezzi), K. adelaidica ( Macquart), Lar. dimidiatipennis ( Bowden), Muw. stellifera ( Walker), and Pa. marginicollis ( Gray); from Ligyra: Eu. enderleini ( Paramonov), Eu. mars ( Bezzi), Eu. monacha (Klug), Eu. paris ( Bezzi), Eu. sisyphus ( Fabricius), and Eu. venus (Karsch).
