Annotated record of the detailed examination of Mn deposits from ARA Islas Orcadas Cruise 11 core stations

The purpose of this volume, the eighth in a series of similar publications (Goodell, 1964, 1965, 1968; Frakes 1971, 1973 ; Cassidy et al., 1977a, 1977b), is to continue a presentation to the research community of sediment core descriptions and attendant data of cored and otherwise obtained sediments retrieved in waters of the Southern Ocean aboard the research vessel, ARA Islas Orcadas (formerly, USNS Eltanin), as a part of the circumpolar survey begun by Eltanin in 1962 (see issue of Antarctic Journal of the United States, Vol. 8, No. 3, 1973). The data presented herein are concerned with the results of coring activities aboard cruise 1176 of Islas Orcadas, the second marine geology coring cruise of this vessel under the terms of the present United States-Argentine agreement.

Visibilidad y percepción en la construcción de un paisaje Prehistórico. El caso de Calviá (Mallorca, Islas Baleares)

El presente trabajo se centra en el estudio del papel que juega el control visual del espacio en las prácticas sociales de las comunidades prehistóricas. Este trabajo se articula a partir de un estudio de caso, el término municipal de Calviá, situado en el sureste de la isla de Mallorca, para analizar las diferentes formas de monumentalidad arquitectónica y cómo estas se constituyen cómo un punto de referencia social dentro del paisaje. Partiendo de una amplia horquilla temporal, que abarcaría el Bronce Naviforme (1550-850 AC), el período Talayótico (850-550 AC) y el Postalayótico (550-123 AC), se propone analizar los cambios y pervivencias en la construcción del paisaje, a través de estrategias de visibilidad, percepción y movimiento alrededor de los monumentos arquitectónicos. A través de la perspectiva de la Arqueología del Paisaje y mediante el uso de Sistemas de Información Geográfica (SIG) se propone un análisis de tendencias a largo plazo en la configuración social de un paisaje.

¿Doble reaseguro o doble inestabilidad?: El papel de EEUU en Asia y el conflicto por las islas Senkaku/Diaoyu

Durante décadas, tras la II Guerra Mundial, EEUU ha jugado un papel clave en la seguridad de Asia Pacífico como estabilizador exterior.En el contexto actual de lucha por la hegemonía en Asia entre los propios Estados Unidos y la República Popular de China esa situación puede estar cambiando. Así parece ponerse de manifiesto en los distintos conflictos planteados en la región y en concreto de las islas Senkaku/Diaoyu divide la República Popular de China y Japón, aliado en el área de Estados Unidos

Patrimonio arquitectónico de las Islas Canarias: nuevas vías de investigación

Tres documentos fundamentales explican la historia de los Planes Especiales de Protección y Reforma Interior del Centro Histórico de Las Palmas de Gran Canaria. El PEPRI de 1985 redactado por los arquitectos Luis Alemany y Faustino García, su revisión en 2001 a cargo de Joaquín Casariego y Elsa Guerra y la última actualización llevada a cabo por el Servicio de Planeamiento del Área de Urbanismo en 2016.

Patrimonio arqueológico de las Islas Canarias

Los paisajes insulares canarios han estado sometidos a transformaciones que, en los tres últimos milenios se han debido, por un lado, a razones estrictamente naturales tales como emisiones lávicas y piroclásticas y por otro a causas antrópicas vinculadas con las prácticas agrícolas y ganaderas desarrolladas a partir de la primera colonización humana. Por lo que a esto último se refiere, en torno al cambio de Era hemos detectado en la isla de Lanzarote una notable degradación del medio asociada a un fenómeno de intensificación económica basada en actividades ganaderas. Desde la perspectiva metodológica se han utilizado datos geo-arqueológicos derivados de intervenciones arqueológicas y análisis sedimentológicos y polínicos efectuados en diferentes yacimientos de Lanzarote datados entre los siglos X a.C. y XIV d.C.
