Contacts under the lens: Perspectives on the role of microstratigraphy in archaeological research

Achieving an accurate perception of time and context remains a major challenge in archaeology. This paper highlights the potential benefits of microstratigraphic study to address this goal, drawing on case studies from Lower, Middle, and Upper Paleolithic, Neolithic, and Iron Age archaeological sites. First, we discuss the importance of site formation reconstruction and the ways in which current field methods approach the sedimentary record. Then, we focus on both field identification and high-resolution study of stratigraphic contacts, which are ubiquitous in archaeological deposits. Examples are presented to highlight the role of microstratigraphy in characterizing the nature of contacts and their significance for archaeological interpretation. A microstratigraphic approach is especially useful for distinguishing between contacts that originate from changes in depositional processes and contacts that form as a result of post-depositional processes such as pedogenesis, diagenesis, or burning. Further examples show how “invisible” anthropogenic surfaces and different kinds of occupation deposits can come to light at a microscopic scale of observation. Finally, we illustrate cases in which what appeared to be sterile layers in the field yielded anthropogenic elements. In the end, we discuss how archaeological projects might incorporate microstratigraphic analyses and their results within broader research frameworks that prioritize site formation process reconstruction.     

The Malleability of Participation: The Politics of Agricultural Research under Neoliberalism in Bolivia

This article analyses how neoliberal restructuring encouraged the use of participatory methods in agricultural research in Bolivia and how, at a later stage, participatory development initiatives had to be adapted to prevent conflicts with the post‐neoliberal views of farmer organizations. The article contributes to the debate on the normalization of participatory methods in agrarian development. Engaging with Foucault's work on governmentality and neoliberalism, our analysis goes beyond interpretations of participation which conceptualize it exclusively as a technology of power to discipline subjects. Drawing on a distinction between a liberal and a neoliberal moment in the restructuring of agricultural research, we study the case of PROINPA (Foundation for the Promotion and Research of Andean Products), a national NGO that was once part of the state system for agricultural research but was then privatized. Although PROINPA employed participation mainly to enhance managerial effectiveness, it also facilitated moments of participation from below. We argue that participation designed by this type of NGO is not just ‘technical’ as PROINPA professionals would like to perceive it, nor is it simply ‘political’ as critical views on participation hold. Instead it is malleable in the sense that each actor is involved in finding a new balance between technical, economic and political considerations.     

The bishop and the Basques: The diocese of Calahorra and the Basque provinces of Alava and Vizcaya under Bishop Rodrigo Cascante, 1147–1190

Under Bishop Rodrigo Cascante (1147–90), the northern Iberian diocese of Calahorra made its first significant administrative inroads into Alava and Vizcaya since its nominal assimilation of those Basque provinces around 1090. An examination into the fluctuating history of Calahorra's administrative penetration of its Basque provinces during this period highlights the extreme difficulty of this undertaking, which was severely hampered by the opposition of a strong Basque regional nobility. It also reveals a close connection between the fluctuations that characterized Calahorra's administrative fortunes north of the Ebro and the see's turbulent political context, defined by its position straddling a volatile frontier between Castile, Navarre and Aragon. Finally, it provides a useful opportunity to analyse Rodrigo Cascante's changing relationships with the secular powers that competed for the territory of his Riojan see. This analysis leads to the conclusion that the bishop of Calahorra was not a passive partner in these relationships, but actively adjusted his stance with respect to the crowns of Castile and Aragon, primarily in function of how well they did, or might, contribute to the realization of his Basque agenda.     

‘It is not fair that he is treated as a commoner’: lower-level native lords in the repartimiento of Macha (Charcas) under colonial rule, 1540–1619

This article studies the impact of colonial rule on Andean hierarchies of power, underlining the role of lower-level native leaders who enabled paramount lords to organize labor services, levy tribute, and govern Andean polities. Using the repartimiento of Macha (Charcas) as a case study, this article examines the impact of external colonial authorities' actions against the backdrop of rising internal tensions within Andean polities. Segmented polities such as Macha faced increasing tensions, giving rise to new mediating roles for lesser-ranking native leaders, placing the subordinate lords' fight for status at the center of debate. This article starts by exploring the first interrelations between lesser-ranking lords and colonial authorities under the encomienda system through the late 1560s. It then turns to the impact of Viceroy don Francisco de Toledo's reforms in the early 1570s, which simplified and standardized native hierarchies of power within each repartimiento while also fragmenting local Andean elites between tribute-paying lords and those exempted of from it. Finally, the article examines the reactions of lower-level native leaders in the face of new constraints regarding tribute exemption and related obligations in the early seventeenth century, as exemplified by indio principal don Diego Chambi.     

Radiometric dates and micromorphological evidence for synchronous domestic activity and sheep penning in a Neolithic cave: Cueva de El Toro (Málaga,Antequera, Spain)

We present radiocarbon dates and preliminary micromorphological information from the Neolithic cave site of Cueva del Toro (Antequera, Málaga, Spain). This site has yielded a rich early and late Neolithic archaeological record. The late Neolithic assemblage reflects specialized handcraft activity including in situ ceramic manufacture, textile production, and food processing along with sheep and goat penning, suggesting that the cave occupants and their domestic animals shared the same living space. Until now, dating of the stratigraphic sequence was incomplete, and the function of the combustion activities carried out at the cave remained unclear. New absolute dates from the main late Neolithic domestic activity area, corresponding to the most intense Neolithic occupation of the cave, allow us to place the entire sequence between 5320 and 5170 BP (or 4250–3950 to 2σ Cal BC). Micromorphological results show that many combustion features from this site represent recurrently burnt episodes on sheep/goat stabling deposits all along the sequence, corroborating human-goat/sheep cohabitation. This practice had not been previously documented in southern Spain for such early dates. Our results exemplify the importance of characterizing archaeological deposits at a microstratigraphic scale of observation.     

Phytolith evidence for hearths and beds in the late Mousterian occupations of Esquilleu cave (Cantabria,Spain)

Esquilleu cave site has provided a moderately well preserved archaeological cave deposit from the Late Pleistocene in the Cantabrian area. Phytolith quantification, identification and determination of the refractive index have been carried out, together with FTIR analyses, from sediment samples collected in the profile. The comparison of the data obtained with the previous micromorphological results allows us to make inferences about the site formation processes and the Neanderthals use of the cave. Phytolith results show the presence of grass leaves nearby the hearth suggesting the repetitive existence of a bedding zone on the same area. Neanderthal behavioral patterns should be revised on the light of high resolution analyses, since diagenetic processes can obscure the existence of differentiated activity areas in the site.     

“Who can play this game?” The lived experiences of doctoral candidates and early career women in the neoliberal university

Work intensification is a characteristic of the current neoliberal trend in academia. Postgraduates and Early Career Researchers (PhD candidates and ECRs) in geography are no strangers to this development but are rarely the focus of publications or dialogue on the (gendered) outcomes of the academy’s neoliberal agenda. Encouraged by the recent emotional turn in the social sciences and humanities, this article seeks to unveil some of the everyday particulars of life in academia for PhD candidates and ECRs under the tide of financial cuts and increased competition for funding. We explore the question: “Who can – and indeed wants to – play this game?” As three early and one mid-career academic women in four different institutions in the Global North, we make use of reflexivity, autobiographical writing, and reflection, to analyze increasingly stressful and demanding working conditions. Through the depiction of our lived experiences, we contend that the push for ever increasing outputs attends most of our time and represents a distinctly different form of scholarship than has been traditionally considered as the pathway into academia, not seldom jeopardizing well-being of young academics, one that needs to be interrogated by geographers.     

POTENTIAL HISTORY: READING ARTIFICIAL INTELLIGENCE FROM INDIGENOUS KNOWLEDGES*

Until the beginning of the twentieth century, history, as a core concept of the political project of modernity, was highly concerned with the future. The many crimes, genocides, and wars perpetuated in the name of historical progress eventually caused unavoidable fractures in the way Western philosophies of history have understood change over time, leading to a depoliticization of the future and a greater emphasis on matters of the present. However, the main claim of the “Historical Futures” project is that the future has not completely disappeared from the focus of historical thinking, and some modalities of the future that have been brought to the attention of historical thought relate to a more-than-human reality. This article aims to confront the prospects of a technological singularity through the eyes of peoples who already live in a world of more-than-human agency. The aim of this confrontation is to create not just an alternative way to think about the future but a stance from which we can explore ways to inhabit and therefore repoliticize historical futures. This article contains a comparative study that has been designed to challenge our technologized imaginations of the future and, at the same time, to infuse the theoretical experiment with contingent historical experiences. Could we consider artificial intelligence as a new historical subject? What about as an agent in a “more-than-human” history? To what extent can we read this new condition through ancient Amerindian notions of time? Traditionally, the relationship between Western anthropocentrism and Amerindian anthropomorphism has been framed in terms of an opposition. We intend to prefigure a less hierarchical and more horizontal relation between systems of thought, one devoid of a fixed center or parameter of reference. Granting the same degree of intellectual dignity to the works of Google engineers and the views of Amazonian shamans, we nevertheless foster an intercultural dialogue (between these two “traditions of reasoning”) about a future in which history can become more-than-human. We introduce potential history as the framework not only to conceptualize Amerindian experiences of time but also to start building an intercultural dialogue that is designed to discuss AI as a historical subject.     

Upper Palaeolithic hunter-gatherer subsistence in Mediterranean coastal environments: an isotopic study of the diets of the earliest directly-dated humans from Sicily

The subsistence of hunter-gatherers in the Mediterranean Basin has been the object of few studies, which have not fully clarified the role of aquatic resources in their diets. Here we present the results of AMS radiocarbon dating and of isotope analyses on the earliest directly-dated human remains from Sicily, the largest island in the Mediterranean Sea. The radiocarbon determinations show that the Upper Palaeolithic (Epigravettian) humans from Grotta di San Teodoro (15 232–14 126 cal. BP) and Grotta Addaura Caprara (16 060–15 007 cal. BP) date to the Late-glacial and were possibly contemporary. The diets of these individuals were dominated by the protein of large terrestrial mammalian herbivores, such as red deer (Cervus elaphus). There is no evidence for the consumption of marine resources, which is probably the result not only of the oligotrophic nature of the Mediterranean, but also perhaps of the lack of adequate technology for exploiting intensively the resources from this sea. In spite of being contemporaneous and of the cultural and technological affinities present between the San Teodoro and Addaura humans, the carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope composition of their bone collagen suggests that significant differences were present in their diets. In particular, the hunter-gatherers from Grotta di San Teodoro, in NE Sicily where coastal plains are backed by high mountain chains (Monti Nebrodi), probably had easy access to resources such as anadromous brown trout (Salmo trutta), which might not have been similarly available in the NW of the island, where reliefs are noticeably lower and watercourses fewer and farther between. This study shows that the high biodiversity of this region, which results from the complex topography of Mediterranean landscapes, was probably exploited opportunistically by Late-glacial foragers. Our data also suggest that intensification and diversification of food acquisition in Sicily did not start in the closing stages of the late Pleistocene, as in other Mediterranean regions, probably because the island had only been (re-)colonized by humans around the Last Glacial Maximum.
