Stable isotope analysis on human remains from the final Early Holocene in the southern Puna of Argentina: The case of Peñas de las Trampas 1.1

In this work are presented the results of isotopic analyses made on bone remains of human individuals (n?=?6) from the southern Puna of Argentina dated to the final Early Holocene (ca. 8230–8000 BP). They were found in structures located in Peñas de las Trampas 1.1, a rockshelter at 3582 m.a.s.l. in Antofagasta de la Sierra, in the southern Argentinian Puna. They contain multiple secondary burials. Bone fragments were recovered from at least six individuals, three in each structure. Stable isotopes of Carbon (δ¹³C) and Nitrogen (δ¹⁵N) analysis were aimed at defining aspects related to the palaeodiet of the six individuals within the palaeo-economic subsistence spectrum typical of hunter–gatherers. It is worth noting that these human remains are among the earliest from North-Western Argentina, where funeral practices are related with the transportation of certain anatomical parts. The palaeodietary inference considers, on the one hand, the extreme aridity of this geographical area and its impact on the isotopic ecology. And, on the other, it takes into account the fact that four of the six individuals under study were breastfed infants. The results are in agreement with the expected values of the period, which has been characterized as the beginning of the arid Altithermal.     

Dating Historical Buildings: An Update on the Possibilities of Absolute Dating Methods

The reconstruction of the history of a building represents a difficult task, as written information is not usually available or incomplete. Some building materials (e.g., bricks, wood) have been classically used for absolute dating while on others has been considered unreliable (e.g., stone). However, developments and tests performed in the last 20 years have shown important advances on the use of such methods, increasing the possibilities of successful reconstruction of building chronologies, although most of these advances are still scarcely known by the community involved in the site management (e.g., archaeologists, architects). Both, radiocarbon and luminescence dating have been the most successful techniques but others, such as archaeomagnetism, can also be used. Even, some important events such as fires could be dated. The purpose of this work is to provide an overview of the last achievements of absolute dating techniques available in building materials.

Maritime Archaeology in Uruguay: Towards a Manifesto

We report a collaborative maritime archaeological project in Uruguay, one of several Latin American countries where the subject is undergoing review in terms of the ways it is practised and managed. Uruguay is typical of many states where there has been a tension between a heritage-based approach in which the results of investigations are viewed as publicly owned, as opposed to the profit motive in which commercial and personal gain is the underlying ethic. This project was conceived both as a way of assisting the Uruguayan Heritage Commission in promoting the former approach as well as advancing a programme of research into the age of global exploration. This paper sets out the rationale of the initial field season and reflects on subsequent developments.     

Spatial distribution of US employment in an urban efficiency wage setting

We analyze whether efficiency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in which shirking at work and leisure are assumed to be substitutes. We use unique data from the American Time Use Survey (ATUS) that allow us to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We confirm that shirking and leisure are substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a worker's time endowment and shirking at work. Our findings point to the existence of efficiency wages in labor markets.     

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.     

La Espiral Cave (Cuba): Guano and signs of Plant Substances Used as Paint Ingredients

At La Espiral cave, located in Bahia Honda municipality (Artemisa province, Cuba), there are several pictographs, including two of particular importance due to the design used: one of concentric circles and another of a spiral. We analyzed the pigments and binders used in one of these pictographs. The chemical ingredients of the paint are considered in this article, as well as the use of bat guano as a major pigment compound. The apparent presence of ellagic acid, ellagitannin, or anthocyanins would strengthen the hypothesis that artists used vegetable protein as a paint binder or solvent.     

New World civitas,contested jurisdictions,and inter-cultural conversation in the construction of the Spanish Monarchy

Jurisdictional frontiers were created, contested, and negotiated among a wide range of actors, including native Americans and Europeans, with reference to the cities founded in Castilla del Oro (roughly present-day Panama). This research deals, first, with the reshaping of the concept of a city in the New World, based on its inhabitants’ sense of civitas. It analyses, secondly, the creation and redefinition of jurisdiction during political conflicts and, third, the construction and maintenance of jurisdiction through local relations with indigenous populations described as ‘conversation’. The analysis of the creation and preservation of local jurisdictions allows for an interpretation of the complexities involved in the configuration of political power and political space from below in the territories claimed by the Spanish Monarchy.     

Catholic students at war: the Federazione Universitaria Cattolica Italiana, 1940–43

Abstract

This article deals with the religious experience of the Federazione Universitaria Cattolica Italiana during the Second World War. Since many of the future Christian Democrat leaders that would rule the country after the conflict were formed in the ranks of the organization, most of the existing literature has tended to focus on the formation of this ruling class and their political trajectory and, has tended to overstate the origins and character of their anti-fascist departure, neglecting the initial support for many aspects of the Regime's war effort. This article contends, instead, that the most salient features of the war experience of the university students are to be located in the spiritual dimension and in their effort to contrive a religiosity adapted to warfare and modernity in general, interlaced with the powerful myth of a Catholic Italy that, at least in the early stages of the conflict, fuelled the expectations of many in the federation of a primordial role to be played by Italy in a new world order.
