Effects of pimozede on the psychopathology of delusional disorder

1. The effects of pimozide on the psychopathology of delusional disorder were studied. 2. After six weeks, pimozide (2-12 mg/day) administration had no effect on the Brief Psychiatric Rating Scale, or in the psychological, social and occupational functioning, as measured by the Global Assessment of Functioning Scale. 3. When the different dimensions of the delusional experience were looked upon, no modifications were observed in any of them after six weeks of pimozide treatment. 4. These data failed to support the therapeutic role of pimozide in the treatment of delusional disorder and may suggest, when compared to other disorders with prominent delusions such as schizophrenia, a different neurobiology for the illness.

Cronología y organizaCión eConómiCa de las poblaCiones arCaiCas de la Costa de taltal

This study is a reassessment of the chronological and cultural sequence of the Archaic Period in Taltal, in an attempt to document the continuities and transformations in the economic organization of local populations who inhabited this area. We base our understanding of this process on new data generated by our project in recent years, as well as previously published studies in the area. This research has been mainly directed towards the understanding of three variables in the economic organization of Taltal’s hunter-gatherer-fisher communities: mobility systems, subsistence practices and technology.

PAISAJES MINERO-METALÚRGICOS INCAICOS EN ATACAMA Y EL ALTIPLANO SUR DE TARAPACÁ (NORTE DE CHILE)

espanolEn el presente trabajo ponemos a prueba interpretaciones en boga que le otorgan a la actividad minera un rol central dentro del expansionismo incaico al norte de Chile, y en particular a la region atacamena y el altiplano sur de Tarapaca. Luego de sintetizar la informacion acerca de la mineria en la region durante el Periodo Intermedio Tardio (ca. 950-1.400 d.C.), revisamos las evidencias arqueologicas de mineria del cobre incaica en la region atacamena y el altiplano sur de Tarapaca (ca. 1.400-1.540 d.C.), reconstruyendo a partir de dicha revision las modalidades de organizacion de la produccion y su administracion, asi como el consecuente paisaje minero-metalurgico instaurado por los Incas en la region. Concluimos senalando que no solo la mineria jugo un rol esencial dentro de la reorganizacion economica incaica en el area de estudio, sino que esta actividad y su simbolismo asociado fueron los ejes alrededor de los cuales el Tawantinsuyu reorganizo los espacios sociales y sagrados a nivel regional EnglishThe present paper examines current interpretations of the importance of mining activity in Inka expansion into northern Chile, and particularly into the Atacama and Southern Tarapaca regions. We first present a synthesis on the evidence for pre-inka and inka copper mining and metallurgy in the study area. We then go on to infer the organizational systems of production and administration of this activity during the Late Period (ca. 1,400- 1,540 AD), and thus reconstruct the mining and metallurgical landscape created by Tawantinsuyu in Atacama and the southern altiplano of Tarapaca. We conclude that not only did copper mining play a major role in the reorganization of economic systems in the region, but that this activity and its symbolic context served as the principal axis of regional Inca social and sacred spaces

PRE-HISPANIC MINING ERGOLOGY OF NORTHERN CHILE: AN ARCHAEOLOGICAL PERSPECTIVE

Mines, spoils, retention walls and pads are the most common material remains of pre-Hispanic mining activity studied by archaeologists. In this paper we will focus on yet another category, the mining ergology, defined as the material artefacts associated with day to day mining activities. Mining ergology seeks to document the technological equipment of the pre-Hispanic miner, which is seldom found in archaeological contexts due to poor preservation of organic materials. The arid conditions of the Atacama desert offer unique conservation possibilities which have shown a varied mining ergology that includes hafted stone hammers bound to wooden handles with rawhide and wool, lithic hammer heads, lithic and wooden shovels, baskets and capachos (rawhide sacks). The study of these components complements our knowledge of pre-Hispanic mining technologies and increases our understanding of the organization of mining operations, the diachrony of mining activity, the variability and continuity of the material record, and therefore of mining and its development in the Andes in general

MINERÍA Y METALURGIA EN LA COSTA ARREICA DE LA REGIÓN DE ANTOFAGASTA, NORTE DE CHILE

Este trabajo da cuenta de los resultados de un proyecto aun en curso acerca de la historia de la mineria y la metalurgia de la zona de Taltal y Paposo. Se presentan datos sobre San Ramon 15, la primera mina prehispanica de oxidos de hierro conocida en Chile, y datada en el Periodo Arcaico. Se plantea que su data indica que la actividad minera en el norte de Chile tendria su origen en la extraccion de pigmentos rojos, antecediendo en varios milenios a la mineria del cobre. Asimismo, se sintetizan diversos datos recopilados con relacion a los objetos metalicos prehispanicos de Taltal y Paposo, centrandose en sus caracteristicas morfologicas y analisis preliminares de composicion quimica, los cuales sustentan la existencia de una metalurgia de caracter local, ademas de la existencia de bienes metalicos importados.

Metalurgia prehispánica en las sociedades costeras del norte de Chile (quebrada Mamilla, Tocopilla)

We present direct and indirect evidences of metallurgical activities by hunter-gatherer and fishers populations of the arid coast of Northern Chile during Late Intermediate and Late periods. We discuss these evidences and propose the existence of a local metallurgical tradition with particular characteristics for the coastal societies in this region. This tradition complements current knowledge about the use and significance of metals in the Andes.

Middle Holocene Production of Mussel Shell Fishing Artifacts on the Coast of Taltal (25° Lat South), Atacama Desert, Chile

ABSTRACT Shell fishhooks have been found in several sites along the Pacific Coast of the Americas, but little is known about prehistoric workshops of these tools and the socio-economic context of their production and distribution. The present study provides new data about the production of mussel (Choromytilus chorus) shell fishing tools (MSFT) at Morro Colorado and Zapatero, two Middle Holocene sites on the coast of Taltal, northern Chile. The MSFT assemblages of the two sites suggest the existence of workshop areas and a specialized manufacture of C. chorus fishhooks associated with an increased dependence on fishing in local subsistence practices. Abundance and type of mussel shell fishing artifacts, preforms, and shell debris at these two shell midden sites are discussed to better understand Prehispanic workshops, the techniques used to work C. chorus shells, and the possible relationship between raw material acquisition, technological change and overall transformations in subsistence practices and levels of social complexity among Middle Holocene coastal groups along the northern coast of Chile.
