Detecting and mapping buried buildings with Ground-Penetrating Radar at an ancient village in northwestern Argentina

We describe an archaeo-geophysical investigation performed near the Palo Blanco archaeological site, Catamarca, Argentina. A large area beyond the northern limit of the site was explored with the Ground-Penetrating Radar (GPR) method in order to detect new buildings. The exploration showed signals of mud-walls in a sector that was located relatively far from the previously known buildings. A detailed survey was performed in this sector, and the results showed that the walls belonged to a large dwelling with several rooms. The discovery of this dwelling has considerably extended the size of the site, showing that the dwellings occupied at least twice the originally assumed area. High-density GPR surveys were acquired at different parts of the discovered building in order to resolve complex structures. Interpreted maps of the building were obtained. Different characteristics of the walls were satisfactory determined, in spite of the low contrast of the dielectric constant at their interfaces and the noticeable spatial fluctuations of the signals due to wall collapses.     

Review of Archaeological Research in Angola

This article examines the historical processes that shaped the development of archaeological practice in Angola during the Portuguese colonial period and the aftermath of political independence. Using published works, unpublished reports, and photographic records, we examine the research themes, actors, scholars, and institutions that influenced archaeological research in the country. We also used documents and museum collections in Angola and Portugal to create a GIS database of Angola’s archaeological findings. This study highlights the events, personalities, and priorities that motivated earlier investigations, and the geographical distribution of prehistoric sites. We hope this study will be a resource for guiding future archaeological research in Angola.

     

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.     

Identifying the Impacts of Land-Use Spatial Patterns on Street-Network Accessibility Using Geospatial Methods

While the land use-street network nexus is well acknowledged, evidence for the one-way impacts of land-use patterns on street accessibility is still inadequate. The measurements of land-use patterns and street accessibility lack systematic knowledge. Their empirical correlations also lack geographical variability, constraining site-specific land-use practices. Therefore, this study overcame the aforementioned limitations by examining the two-level spatial models to formulate accessibility-oriented land plans, using a well-developed Chinese city as an example. Firstly, two landscape metrics—Euclidean Nearest-Neighbor Distance (ENN) and Similarity Index (SIMI)—were used to quantify the intra- and inter-land-use configurations, respectively. Both city-level and local accessibility were measured using spatial design network analysis. Performing both ordinary least squares (OLS) and geographically weighted regression (GWR) models, results identified the statistically significant effects of inter-land-use patterns on two-level street accessibility. An exception was that land-use configurations within residential and industrial regions were irrelevant to street accessibility. We also found GWR was a better-fitting model than OLS when estimating locally-varied accessibility, suggesting hierarchical multiscale land-use planning. Overall, locally heterogeneous evidence in this study can substantialize land use-street network interactions and support the decision-making and implementation of place-specific accessibility-oriented land use.     

Anthropologie, psychhanalyse et «civilisation» du brésil dans l'entre-deux-guerres

This study concerns the moral regulation of the Person in Brazil from the twenties to the end of the forties, from the point of view of the intense academic relationship between anthropology and psychoanalysis. It deals with the conditions under which that dialogue took place: the general crusade for the «civilization» of the country, between the central State initiatives in the promotion of hygiene and education and the medical, intellectual debates about the «African» heritage and the possibility of surmounting cultural «backwardness».     

Breaking the Silence: Mexican Children and Women's Confrontation of Bracero Family Separation, 1942–64

On 6 August 1942, the Mexican and US governments’ recruitment of Mexican men into the temporary contract labour programme known as the Bracero Program initiated a process that would deteriorate Mexican children and women's personal wellbeing and relationships to each other. The Bracero Program left children to endure the absence of their bracero fathers, while married women and caretakers transitioned into single motherhood under conditions and terms that drove an uncalculated number of these women into undocumented migration to the United States. Separation from their mothers further devastated children. The silence concerning the programme and the whereabouts and intentions of their immigrant parents alienated children from the mothers and caretakers left to care for them. Hence, mothers, caretakers and teachers came together to listen and talk to their children and each other about the dangerous realities of the programme in order to overcome the alienating silence driving them apart within the borders of Mexico. Using archival sources and the oral life‐histories of fifty Mexican children and women who endured the programme's separation of their families in San Martin de Hidalgo, Jalisco, Mexico, I argue that the anxiety and loss of Mexican children and women inspired mothers, caretakers and teachers to transition into instilling a gendered and transnational understanding of the dangers of the programme to their children and among themselves to prevent the onset of permanent alienation from each other.     

Universities,the Second Academic Revolution and Regional Development: A Tale (Solely) Made of “Techvalleys”?

Universities are crucial organizations in the knowledge society. As such, a new social contract between academia and society is being developed, inducing significant dynamics of change in academia. Change is configured by the integration of economic development in the mission realm of universities, together with teaching and research, which set off an academic revolution. This revolutionary move within academia is being scholarly analysed mostly from the perspective of technology transfer and spin-off firms' development. Taking into account the nature and challenges of the contemporary society, this paper acknowledges that these dominant approaches to the changing academic mission provide an incomplete picture of the role universities can play in development processes. Accordingly, it uses a broader perspective on the academic revolution in order to detail the developmental role played by higher education and the relevant development resources that universities can provide and left out of the mainstreamed picture. It suggests that the need for broadening the perspective gains increased relevance when trying to know more about the role universities play in regional development. It asserts that universities, as regional development agents, are essential to help regions to combine and mobilize the knowledge and relational resources that nourish the capacity for collective action, i.e. to build up regional institutional capacity.     

Canary islands aborigin sex determination based on mandible parameters contrasted by amelogenin analysis

Sex determination using mandible parameters is population dependent. In order to assess which measurements better characterize sex in prehispanic individuals from the Canary Islands, we blindly contrasted the results obtained by visual inspection and osteometric measurements with those obtained by molecular sexing using amelogenin ancient DNA analysis on teeth from the same material. Unambiguous sex classification was achieved by amplification of sex specific amelogenin alleles in 56 out of 76 mandibles (73.78% of the cases). Visual inspection led to a correct diagnosis in 66.04% of cases, with a greater proportion of errors for female (54.17%) than male (17.24%) mandibles. Osteometric measurements were able to assign sex correctly in 72.2% in the best of cases (mandibular height), a proportion similar to that obtained using a discriminant function (71.2%). By logistic regression analysis, ramus breadth, index ramus breadth/ramus height and mandibular length were the parameters independently related with a mistaken diagnosis of female sex, whereas bigonial width, ramus height and mandibular length were the parameters more closely and independently related to a mistaken diagnosis of male sex. In conclusion, diagnosis based on visual examination of the mandible or on its metric measurement only serves to roughly estimate sex with an accuracy of around 70% or less, at least among the prehispanic population from Gran Canaria. Amplification of amelogenin alleles leads to unambiguous identification of male and female alleles in 73.68% of cases, at least among the prehispanic population from Gran Canaria.
