Seismic Vulnerability of an Inventory of Overturning Objects

A methodology is presented for assessing the probability of overturning under the action of ground motions of given intensities, and the expected values and standard deviations of damage produced by overturning of objects in a group or inventory exposed to the same seismic event. We apply this methodology to one example of the typical contents located on the base (i.e., free-field) of a middle-class house or apartment. A detailed inventory was gathered, and recent well-recorded accelerograms at the site were used to compute the rocking response of every object. Vulnerability functions for the whole inventory computed at four different sites in terms of epicentral distance and site effects show large differences between them.     

Goldsmithing traditions and innovations in colonial Colombia: an analytical study of crucibles from Santa Cruz de Mompox

SUMMARY: The 16th-century Spanish conquest of Colombia brought new technologies that altered and interacted with native metalworking traditions. In the colonial village of Santa Cruz de Mompox, renowned because of its goldsmithing tradition, indigenous groups and Spaniards experienced momentous encounters of individuals, metallurgical technologies and knowledge. However, little is known concerning colonial metallurgy, its continuities and changes with regards to the pre-Columbian period. Here we present the analytical characterization of five crucibles recovered in Mompox, together with discussion of relevant archival evidence. We find evidence for the local manufacture of crucibles as well as for the melting of unrefined gold dust, tumbaga (gold-copper-silver alloys) and silver. These metallurgical practices illustrate some likely illegal activities, continuities with pre-Columbian traditions in the use of tumbagas, and the Spanish-led introduction of silver in northern Colombia. It is argued that metallurgical remains can be informative of wider social and economic negotiations that engaged indigenous peoples, mestizos and Spaniards, which are critical to understand the configuration of the colonial reality.     

The Study of Archaeological Floors: Methodological Proposal for the Analysis of Anthropogenic Residues by Spot Tests,ICP-OES,and GC-MS

The identification of chemical activity residues on archaeological surfaces requires the analysis of large numbers of samples, which can be costly and time consuming. Researchers wishing to apply sediment chemistry often are confronted with a dilemma of which technique to use and how to accommodate sediment chemistry into their budget. We propose an approach to the identification of chemical activity residues in which semiquantitative spot tests, which are cheap, quick, and easy to apply, are employed as an initial phase of analysis in order to leverage the results of more time-consuming and costly instrumental techniques. Three examples that pair spot tests with gas chromatography-mass spectroscopy and inductively coupled plasma-optical emission spectrometry analysis show that spot tests successfully identify areas of interest. This approach can save both time and research funds.     

Technological aspects of Mesopotamian Uruk pottery: estimating firing temperatures using mineralogical methods,thermal analysis and luminescence techniques

The Middle Uruk phase in Mesopotamia (3600–3500 bc) has been characterised by the massive production of “bevelled rim bowls” (BRBs). They are characterised by their similar shape and volume in Mesopotamia and surroundings. However, their production method has not been studied in detail, including the firing temperature. The determination of the firing temperature of ancient pottery has been attempted by studying mineral phase transformation sequences; although, very little knowledge exists about such transformations in mixtures or thermal analyses. These methods usually provide imprecise firing temperatures between 500 and 800 °C, as other factors such as the raw materials or firing time and conditions must be considered. As an alternative, luminescence techniques have been tested with promising results, as they have provided reliable maximum firing temperatures for ancient pottery at mild conditions (below 600 °C) with high precision. In this work, the firing temperatures of BRB samples from two archaeological sites located in the Middle Euphrates Valley (Syria) have been studied using mineralogical, chemical and thermal analysis. Both mineral characterization techniques and thermal analyses show agreement and firing probably below 600–700 °C. Luminescence yields ambiguous results but circumstantial evidence on the firing temperature between 400 and 550 °C.     

First Approach to Study the Presence of Domesticated Camelids (Lama glama) in the Chaco‐Santiago Region,a Marginal Zone of the South Central Andes

We analysed bone remains of camelids from the Maquijata site, assigned to the late pottery‐making and farming stage (ca. 800–400 BP), in order to differentiate between domestic and wild species in the Chaco‐Santiago archaeological region. This region is considered marginal to the Argentine Northwest regarding its cultural development and has received less attention than other regions. South American camelids have been one of the major resources in this continent, with domestication recorded in the South Central Andes at around 4400–3000 BP. We applied osteometric techniques and multivariate statistical analyses to proximal phalanges; the results showed interspecific differentiation of archaeological specimens, though with some methodological application issues. These results are the first contribution regarding the presence of domesticated animals in the study area. Copyright © 2012 John Wiley & Sons, Ltd.     

The Upper Paleolithic Rock Art of Iberia

Nearly 200 rock art sites of Upper Paleolithic age are currently known on the Iberian Peninsula, in both caves and the open air. Over half are still concentrated in Cantabrian Spain and they span the period between c. 30–11 kya, but–tracking the course of human demography in this geographically circumscribed region–many of the images were probably painted or engraved during the Solutrean and, especially, Magdalenian. Dramatic discoveries and dating projects have significantly expanded the Iberian rock art record both geographically and temporally in recent years, in close coincidence with the growth of contemporaneous archeological evidence: cave art loci in Aragón and Levante attributable to the Solutrean and Magdalenian, many cave art sites and a few open-air ones in Andalucía and Extremadura that are mostly Solutrean (in line with evidence of a major Last Glacial Maximum human refugium in southern Spain), the spectacular Côa Valley open-air complex in northern Portugal (together with a growing number of other such loci and one cave) that was probably created during the Gravettian-Magdalenian periods, and a modest, but important increase in proven cave and open-air sites in the high, north-central interior of Spain that are probably Solutrean and/or Magdalenian. Despite regional variations in decorated surfaces, themes, techniques and styles, there are broad (and sometimes very specific) pan-Iberian similarities (as well as ones with the Upper Paleolithic art of southern France) that are indicative of widespread human contacts and shared systems of symbols and beliefs during the late Last Glacial. As this Ice Age world and the forms of social relationships and ideologies that helped human groups survive in it came to an end, so too did the decoration of caves, rockshelters and outcrops, although in some regions other styles of rock art would return under very different conditions of human existence.     

Establishment Radical: Assessing the Legacy of Reinhold Niebuhr's Reflections on the End of an Era

This article argues that Reinhold Niebuhr's most politically radical work, Reflections at the End of an Era (1934) is more determinative of his subsequent political theology than Niebuhr scholarship has acknowledged. In particular, the doctrine of grace and view of history that Niebuhr here developed continued to shape his mature thought, infusing his work with a politically unsettling quality that Niebuhr scholarship routinely overlooks in favor of depicting him as the “establishment theologian.” This article maintains that reclaiming the legacy of Reflections will enable future reception of Niebuhr to recover the radical dimension to his thought.     

Pornoprecariedad: crisis biopolítica,trabajo y régimen visual en Hermosa juventud (Jaime Rosales, 2014)

ABSTRACT

Entendiendo por “pornoprecariedad” el entramado visual que explota y consume como forma de entretenimiento la exhibición de las nuevas formas de miseria en las que se sostiene y que reproduce el neoliberalismo, en este artículo se analiza cómo el largometraje de ficción Hermosa juventud (2014), de Jaime Rosales, cuestiona constructos sobre los que se asienta dicho acercamiento mediático dominante a la precariedad. Relacionar críticamente precariedad con pornografía hace emerger problemáticas relacionadas con la representación visual, la recepción de esta y la dimensión ética de ambas, planteando interrogantes acerca de la responsabilidad, el mirar o las relaciones de género y poder. El film de Rosales dialoga con tradiciones artísticas y reflexivas que trabajan con desarrollos socioeconómicos de largo alcance que la crisis biopolítica patente especialmente desde 2008 en la Europa meridional ha sacado a la luz.
