Ancient Egypt in Brazil: A Theoretical Approach to Contemporary Uses of the Past

In this paper we consider archaeology as a product of social interaction, and discuss how ancient Egyptian materiality has been an important part of identity building in Brazil. We begin by reviewing our theoretical setting, and suggest that a postmodern approach is most helpful to our goal of understanding the social context of the public uses of archaeology. The paper then turns to the trajectory of “Egyptomania” in Brazil, from the 19th century onwards, highlighting the importance of cultural movements such as Kardecism and Masonry in this trend. We argue that the use of Egyptian subjects in Brazil has connections with social inequality, racism, and gender biases. Finally, we present a case study on positive recent trends in the presentation of ancient Egypt in school textbooks which highlights critical approaches to the use of ancient Egyptian subjects in contemporary Brazil.     

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 Using published works, unpublished reports, and photographic records, we examine the research themes, actors, scholars, and institutions that influenced archaeological research in the country.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.

     

A Simulation Study to Explore Inference about Global Moran's I with Random Spatial Indexes

Inference procedures for spatial autocorrelation statistics assume that the underlying configurations of spatial units are fixed. However, sometimes this assumption can be disadvantageous, for example, when analyzing social media posts or moving objects. This article examines for the case of point geometries how a change from fixed to random spatial indexes affects inferences about global Moran's I, a popular spatial autocorrelation measure. Homogeneous and inhomogeneous Matérn and Thomas cluster processes are studied and for each of these processes, 10,000 random point patterns are simulated for investigating three aspects that are key in an inferential context: the null distributions of I when the underlying geometries are varied; the effect of the latter on critical values used to reject null hypotheses; and how the presence of point processes affects the statistical power of Moran's I. The results show that point processes affect all three characteristics. Inferences about spatial structure in relevant application contexts may therefore be different from conventional inferences when this additional source of randomness is taken into account.     

Révolution industrielle logique et signification de l'opératoire

In England, during the first half of the xix^th century, a network organised around Charles Babbage (1791–1871), John F. W. Herschel (1792–1871), George Peacock (1791–1858), Duncan F. Gregory (1813–1844), Augustus de Morgan (1806–1871), George Boole (1815–1864), and other less known authors renewed the status of algebra in a peculiar way. As a result, their works are often considered to mark the birth of abstract algebra. But these algebraists were also involved, as reformers, in the new organisation of science. Taking this into account, I propose a more contextual reading of their works, which can then be understood as side-effects of the Industrial Revolution (1760–1830). These works are analysed as cultural mediators between the roots of University teaching, founded on fidelity to the Ancients on the one hand, and new forms of construction of knowledge on the other. Such a mediation brought together algebra and logic for the first time.     

THE FOOD VALUE CHAIN AS A LOCUS FOR (DIS)AGREEMENT: CONVENTIONS AND QUALITIES IN THE SPANISH WINE AND NORWEGIAN SALTED COD INDUSTRIES

According to the theory of conventions, food value chains (FVCs) involve a complex array of actors who share an agreement about the qualities embodied in their particular foodstuff. Nevertheless, that agreement is continuously challenged by changes in consumer markets. Therefore, I argue that FVCs able to adapt those qualities to new trends will perform better than FVCs whose commitment to certain qualities leads to a misunderstanding between producers and consumers. The organization of the chain itself, the values of national regulatory frameworks, and the goals of the national innovation system are discussed as factors that shape an FVCs' ability to re‐arrange that core agreement. By using professional reports, statistical records and personal interviews, this article focuses on two FVCs that have experienced contrasting trajectories in recent decades in the Spanish market: the wine industry located in the region of Castile and Leon (Spain) and the Norwegian salted cod industry. The growing wine FVC has achieved a successful agreement about a set of qualities linked to nature, tradition, and place, all of them guaranteed by the reputation of the Designation of Origin (DO) system. In contrast, the salted cod FVC is losing its market share because its main actors are failing to properly communicate the key qualities of environmental sustainability and artisanal cod production to concerned Spanish consumers, as well as in the adoption of the place‐related attributes that still shape consumer preferences in Spain.
