Guanaco (Lama guanicoe) isotopic ecology in southern South America: spatial and temporal tendencies, and archaeological implications

We synthesize and discuss available isotopic data on Holocene guanaco samples from southern South America, extending from Tierra del Fuego Island to northern Patagonia and the Pampean region. We evaluate temporal and spatial tendencies on the basis of 91 samples (mainly based on δ¹³C_collagen values), presenting implications for paleodietary research in archaeology. We conclude that there are no strong correlations with latitude in the macro-spatial scale, while there is a set of interesting patterns at smaller regional scales. These patterns lead us to evaluate the role of ecologic and topographic variables (e.g. canopy effect, variations in altitude, ecotones) in structuring isotopic variability. Finally, on the basis of the present analysis we suggest a number of hypotheses and perspectives for the use of stable isotopes as geographic tracers of guanaco distribution in the past, and specific implications for the paleodietary study of human samples.     

The Effect of Public Infrastructure on the Private Productive Sector of Spanish Regions

In this paper we analyze the effect of infrastructure on the cost and productivity performance of the private productive sector of Spanish regions over the period 1980–1993. We use a dual approach based on cost functions that allows us to recover the usual parameters estimated with production functions. In addition, we obtain rates of return and cost elasticities of production factors at the regional level. Our framework explicitly considers that some factors are quasi-fixed and their volume can differ from their optimal endowment levels. Our results indicate that the public sector has contributed significantly to enhance productivity and reduce costs in the private sector of almost every Spanish region. Nevertheless, there is still scope for the government to continue its investment efforts, given that there remains an appreciable gap between observed and optimal public capital, and we find that in the long run, public capital promotes private investment.     

The experiments of Ramón M. Termeyer SJ on the electric eel in the River Plate region (c. 1760) and other early accounts of Electrophorus electricus

This paper focuses on Ramón M. Termeyer SJ (1737-1814?), a naturalist who experimented with the electric eel in the River Plate region during the 1760s. After going through an enumeration of the chroniclers that since the sixteenth century noticed the benumbing discharge of Electrophorus electricus, the article summarizes the work that immediately preceded Termeyer's and considers as a term of comparison the experiments on the electric eel performed by Bertrand Bajon (fl. 1751-1778) in the French Guyanne. It ends by discussing the meaning of Termeyer's 1781 and 1810 articles in the light of contemporary ideas of animal electricity.     

Microeconomic Formulation and Estimation of a Residential Location Choice Model: Implications for the Value of Time

Abstract We formulate a microeconomic model of residential location choice behavior as an aggregate of the individual behaviors of household members, subject to individual time constraints and a common income budget. A simplified version of the model is estimated from stated preference rank‐order data, yielding a function that may be interpretated as a conditional indirect utility function. We consider Box‐Tukey transformations, segmentation by income class, and a consistent treatment of data at different rank depths using the simultaneous mixed‐estimation method. Measures of the household's willingness‐to‐pay (through rents) for reducing travel times to work and study in the short run, are interpreted as subjective values of time and compared with such values derived from mode choice models. Our results are plausible, and consistent with recent findings showing that the short‐run benefits of transport projects derived by transport models are larger than benefits measured at the land use system.     

Understanding Population Decline Trajectories in Spain using Sequence Analysis

Population decline is a key contemporary demographic challenge. Previous work has measured the national extent of population decline, and we know that it is more acute in Japan and Eastern Europe and is set to accelerate across many industrialized countries. Yet, little is known about the population trajectories leading to current trends of depopulation and their underpinning demographic and contextual factors. To address this gap, we aim to identify and characterize the different trajectories of depopulation in Spain from 2000 to 2020 at the small area level using sequence analysis, spatial autocorrelation analysis, decomposition techniques, and multinomial logistic modeling. We show that while Spain recorded an overall 17.2% national population growth between 2000 and 2020, 63% of municipalities experienced depopulation. We identify six trajectories of population decline, with a well-defined northwest-south divide. These trajectories include mostly rural municipalities, but also certain small- and medium-sized cities. Natural decline comprises the main demographic component underpinning differences in the extent of depopulation across trajectories, and international migration plays an important role in explaining transitions to decline since the financial crisis of 2008. Small and old populations, and, to a lesser extent, remoteness from cities are key features characterizing areas of high decline.     

From deep to shallow fluid reservoirs: evolution of fluid sources during exhumation of the Sierra Almagrera,Betic Cordillera,Spain

The combination of structural, geochemical and palaeotopographic data proves to be an efficient tool to understand fluid transfers in the crust. This study discriminates shallow and deep fluid reservoirs on both sides of the brittle–ductile transition under an extensional regime and points out the role of major transcurrent fault activity in this palaeohydrogeological setting. Palaeofluids trapped in quartz and siderite–barite veins record the transfer of fluids and metal solute species during the Neogene exhumation of the Sierra Almagrera metamorphic belt. Ductile then brittle–ductile extensional quartz veins formed from a deep fluid reservoir, trapping metamorphic secondary brines containing low‐density volatile phases derived from the dissolution of Triassic evaporites. During exhumation, low‐salinity fluids percolated within the brittle domain, as shown by transgranular fluid inclusion planes affecting previous veins. These observations indicate the opening of the system during Serravalian to early Tortonian times and provide evidence for the penetration of surficial fluids of meteoric or basinal origin into the upper part of the brittle–ductile transition. During exhumation, synsedimentary transcurrent tectonic processes occurred from late Tortonian times onwards, while marine conditions prevailed at the Earth's surface. At depth in the brittle domain, quartz veins associated with haematite record a return to high‐salinity fluid circulation suggesting an upward transfer fed from a lower reservoir. During the Messinian, ongoing activity of the trans‐Alboran tectono‐volcanic trend led to the formation of ore deposits. Reducing fluids caused the formation of siderite and pyrite ores. The subsequent formation of galena and barite may be related to an increase of temperature. The high salinity and Cl/Br ratio of the fluids suggest another source of secondary brine derived from dissolved Messinian evaporites, as corroborated by the δ³⁴S signature of barite. These evaporites preceded the main sea‐level drop related to the peak of the salinity crisis (5.60–5.46 Ma).     

Gender,Legend, and the Icelandic Countryside in the Long Nineteenth Century: Re-Engaging the Archives as a Means of Giving Voice to the Women of the Past

This article addresses the way in which, in spite of their accepted drawbacks (which often include an over-emphasis on male informants), folklore archives can be used to reconstruct the oral traditions of women from earlier times, especially when used in combination with other archival sources that are increasingly becoming available online. In Iceland, the recorded interviews by the folklore collector Hallfreður Örn Eiríksson in the 1960s and 1970s have proven to be a particularly useful source for engaging with the reconstruction of women’s narrative traditions in Iceland. These interviews not only provide us with women’s narratives told in their own voices, but also yield a wide range of additional information about the context of women’s storytelling within the rural society of previous centuries.     

Between political emancipation and creole hegemony: Viscardo’s Letter to the Spanish Americans (c. 1791)

Viscardo’s Letter to the Spanish Americans inaugurates a tradition of nonconformist political writing against Spanish colonial rule during the second half of the eighteenth century, a period characterized by the Crown’s attempt to reorganize several aspects of the colonial administration. As an ex-Jesuit living in exile after the expulsion of the Society of Jesus from all Spanish territories in 1767, Viscardo had a political as much as a personal motive in designing a project that would cut the colonial ties between Spain and the New World. His plans for emancipation included the instauration of a monarchical form of government, but his design was out of touch with reality and would have hardly been taken seriously by the inhabitants had a British-backed expeditionary force reached the coasts of Chile and Peru, as he had planned. While Viscardo’s Letter may have stirred a sense of creole patriotism some years after his death, the political scruples of the ancien regime based on social privileges and racial distinctions were too strong to be dismantled by mere ideals of freedom, justice and equality. Thus, effective political participation was restricted to the creole elite, whom Viscardo saw as the legitimate guarantor of social order and economic prosperity.     

Innovations in cultural policy and development in Latin America

ABSTRACT

This essay looks at two major tendencies in cultural policy recommendations in Latin America: (1) the economic contribution of arts, heritage and especially the cultural and creative industries; and (2) cultural rights, with a focus on inclusion, access, empowerment, and the integral development/well-being of citizens. The two tendencies, which are part of cultural development policies, are not easily integrated into an all-encompassing policy because they follow different logics and management strategies. Nevertheless, both of these tendencies, which emerged in the heyday of neoliberalism (the 1990s), continue to provide the major justifications for cultural funding, although the current economic crisis has led to budget cuts. After a review of cultural development policies, this essay examines innovative strategies to compensate for scarce funding, including those that seek to bridge both tendencies. The cases examined below correspond to discussions of cultural policies in Latin American forums with hundreds of policy-makers and analysts over the past 20-plus years.

Biological differences related to cultural variability during the Neolithic in a micro-geographical area of the Iberian Peninsula

This paper presents dental morphological data of Neolithic, Chalcolithic and Bronze Age populations from the Catalan Pre-Pyrenean area. The Neolithic group, in particular, differs from those of surrounding areas in its funerary culture: the building of cists, which is not present in the Sepulcres de Fossa Culture. A minimum number of 118 individuals from this area were studied for this work, and the data were compared with those of other Iberian and European groups. The results indicate that the two micro-regional groups from the Catalan area (Pre-Pyrenean and Pre-Coastal) were biologically different during the Neolithic and the Chalcolithic, but not in the Bronze Age, when they also appeared to be more homogeneous culturally. In addition, both areas differ biologically from coetaneous Italian groups, although those closer to the coast show slightly smaller differences. Finally, the Bronze Age groups also present fewer differences with regard to the Italian Bronze Age’s group. Therefore, the results suggest that the Catalan Neolithic population had two separate origins, related to cultural patterns, and that differences between the groups decreased within time, probably due to trade-related activities. Moreover, the fact that the difference with Italian populations decreased during the Bronze Age suggests major population movements through the Mediterranean that would affect the biological composition of the human groups.
