El presente artículo expone una redescripción de la primera persona gramatical en términos de su funcionamiento lógico-pragmático: qué -acción- cuenta como práctica lingüística de enunciación de \"yo\" como operación anafórica. Para conseguir este propósito, se utiliza la noción de anáfora como vínculo inferencial con estructuras suboracionales substituibles, y estas a su vez con estructuras proposicionales articuladas inferencialmente. Además, se cuenta con la noción de juegos de lenguaje y formas de vida -Lebensformen- en tanto adiestramiento para la práctica de dicho jugador. En este sentido, se sigue plenamente la estructura que Robert Brandom desarrolla en Hacerlo explícito. En definitiva, el enunciante de \"yo\" debe articular los contenidos conceptuales que se adscribe de manera anafórica para que se establezca un entramado coherente de compromisos deónticos.

Reichenbachian approaches to indexicality contend that indexicals are 'token-reflexives': semantic rules associated with any given indexical-type determine the truth-conditional import of properly produced tokens of that type relative to certain relational properties of those tokens. Such a view may be understood as sharing the main tenets of Kaplan's well-known theory regarding content, or truth-conditions, but differs from it regarding the bearers of truth-conditional import and truth-conditions. Kaplan has criticized these approaches on different counts, the most damaging of which is that they make impossible a 'logic of demonstratives'. The reason for this is that the token-reflective approach entails that not two tokens of the same sentential type including indexicals are guaranteed to have the same truth-conditions. In this paper I rebut this and other criticisms of the Reichenbachian approach. Additionally, I point out that Kaplan's original theory of 'true demonstratives' is empirically inadequate, and claim that any modification capable of accurately handling the linguistic data would have similar problems to those attributed to the Reichenbachian approach. This is intended to show that the difficulties, no matter how real, are not caused by idiosyncrasies of the 'token-reflexive' view, but by deep facts about indexicality.

Coronet Metals Inc. (\"Coronet\" o la \"Compania\") (TSX VENTURE: CRF.H) se complace en anunciar que ha completado la adquisicion de una participacion de 100 por ciento en Golden Eagle Resources Peru S.A.C. (\"Golden Eagle\"), el propietario de las concesiones mineras del Proyecto de Oro Yanamina localizado en el Peru, a Westmag Resources Limited (\"Westmag\"), una subsidiaria de Latin Gold Limited. Luego de su comunicado de prensa del 28 de marzo de 2011, la Compania pago a Westmag, un total de US$7,5 millones (US$6,5 millones en efectivo y US$1 millon en acciones de Coronet a un precio estimado de $0,30 por accion) para la adquisicion de Golden Eagle y una base de datos con informacion sobre la propiedad mineral sudamericana poseida por Latin Gold and Westmag. Golden Eagle es el propietario registrado de las concesiones minerales que componen el Proyecto de Oro en fase avanzada Yanamina (antes \"Paron\"). Los pagos posteriores adeudados a Latin Gold siguen siendo los indicados en el comunicado de prensa del 4 de enero de 2011 de la Compania. Conjuntamente con la adquisicion del Proyecto de Oro Yanamina, Coronet ha cerrado una colocacion privada directa de 36.172.010 unidades por valor de $10.851.603. Cada unidad consta de una accion ordinaria de la Compania y la mitad de una garantia de compra de acciones (cada garantia completa, una \"garantia o warrant\"). Cada garantia otorga derecho al titular de la misma para adquirir una accion ordinaria adicional a un precio de $0,50 por un periodo de 24 meses a partir de la finalizacion de la oferta. El vencimiento de las garantias esta sujeto a aceleracion de tal manera que, si el precio medio ponderado por volumen de las acciones ordinarias superara $1,00 por veinte jornadas financieras consecutivas, la Compania podra notificar a los titulares de las garantias que estas venceran el dia 30 despues de dicha notificacion a no ser que se ejerzan antes de esa fecha. Latin Gold, como parte de la adquisicion, acordo la compra de un total de 3.261.183 unidades en la colocacion privada directa.

\"Esta situacion constituye una nueva evidencia de que es inviable e irracional aplicar cargas sociales tan altas a salarios tan bajos\", explica Jorge Colina, investigador de Idesa. \"Un monto no remunerativo -aclara [David Scott Kaplan]- implica una jubilacion mas baja. Creo que los trabajadores deberian tener en cuenta esto. Es una vision muy cortoplacista y a la hora de retirarse tendran una menor jubilacion.\"

Briefly, though, [Adams] got great relief from her remitting/ relapsing MS. She twice received monthly injections of Tysabri, before Biogen Idec Inc. and Elan Corp. voluntarily suspended sales on the U.S. market in early 2005, just months after it had first received FDA approval. The move was prompted by concern that three patients had developed progressive multifocal leukoencephalopathy (PML), which is a rare and potentially deadly disease of the central nervous system. \"I am really excited for Tysabri,\" says Adams, a Salt Lake woman who also serves as a National MS Society ambassador. \"I am concerned about the safety, but I think with any of the drugs there are potential safety risks. In the two doses I did take of Tysabri, I had more energy than I'd had in years. And it happened quickly.\" The best treatments currently on the market, Adams says, only help slow progression of MS 30-35 percent. Tysabri did much better than that in earlier clinical studies and in its short-lived availability, as well as in recently published studies, which cited 68 percent fewer relapses with Tysabri than without it.

A seda é uma proteína fibrosa, produzida por glândulas. A seda, que é um líquido no interior do organismo, torna-se sólida ao deixá-lo. As proteínas se dobram de maneiras complexas, dando a cada tipo de seda as suas propriedades únicas. Há limitações para produzir a proteína da seda de aranha em outros organismos, pois o processo de reconstituir as proteínas arruína qualquer padrão relacionado às dobraduras. Mas [David Kaplan], que passou anos aprendendo os mecanismos fundamentais de montagem da seda, está obtendo progressos. \"O processo inteiro\", disse ele, \"está sendo construído em torno de controlar o teor de água\". David Porter, cientista da Universidade de Sheffield, no Reino Unido, disse que os esforços para fazer um equivalente sintético da seda da aranha não resultam em materiais muito diferentes de outros polímeros. \"Quase qualquer um consegue fazer uma seda razoável\", disse Porter. \"Mas não dá realmente para diferenciá-lo de um bom nylon. Para diferenciar o produto natural, é realmente preciso obter as vantagens que a natureza incorpora.\"

U.S.News reports that the controversial program began in early 2002 and has been run by the FBI and the Department of Energy's Nuclear Emergency Support Team (NEST). At its peak, the effort involved monitoring 120 sites in Washington DC per day, nearly all of them Muslim. Sites monitored included mosques, homes, businesses and warehouses, as well as similar sites in at least five other cities when threat levels there have risen: Chicago, Detroit, Las Vegas, New York, and Seattle. Officials conducted daily monitoring for some ten months and have resumed daily checks during periods of high threat.

Luechtefeld discusses his second-in-a-series interview with one of the most renowned interviewers in the field of investigative reporting, David E. Kaplan. In the interview, Kaplan shares his cross-cultural experiences and techniques in dealing with investigative reporting.
