Towards a Multi-Agent-Based Modelling of Obsidian Exchange in the Neolithic Near East

This paper examines an alternative approach to previously proposed models of prehistoric exchange such as the law of monotonic decrement or the down-the-line exchange model developed by Renfrew (Proceedings of the Prehistoric Society 34: 319–331, 1968, Renfrew 1977) to explain the distribution of obsidian across the Near East during the Neolithic period. Renfrew’s down-the-line model, which results in a very regular and clustered network, does not permit the circulation of obsidian to regions of the Near East that are further than 300 km from the source zones, as is shown in the archaeological data available. Obsidian exchange is a complex system where multiple factors interact and evolve in time and space. We therefore explore Agent-Based Modelling (ABM) so as to get a better understanding of complex networks. ABM simulations of an exchange network where some agents (villages) are allowed to attain long-distance exchange partners through correlated random walks are carried out. These simulations show what variables (population density, degree of collaboration between villages…) are relevant for the transfer of obsidian over long distances. Moreover, they show that a type of small-world exchange network could explain the breadth of obsidian distribution (up to 800 km from source) during the Near Eastern Neolithic.     

Paper 1: The Coudenberg Archaeological Site in Brussels: The Stakeholders Involved in the Renovation Process

Abstract

The last material evidence of the former Palace of Brussels, the Coudenberg archaeological site, is situated at the heart of the city, constitutes a remarkable part of its heritage, and has been listed as a legally protected monument. Following the redevelopment of the Royal Quarter in the eighteenth century, the successive archaeological discoveries of the last twenty-five years, and the progressive growth of the areas accessible to the public, the various components of the site have not all been preserved in the same condition. The work involved in developing such a complex has already necessitated considerable resources, and still requires more today. The owners, the City of Brussels and the Brussels-Capital Region, as well as the site’s managers, the not-for-profit association ‘Palais de Charles Quint’, are continuing their programme of developing, promoting, and preserving the remains in order to hand down this important historical evidence to future generations.     

Estimating the Number of Combatants during the Mixtón War in the Peñol de Nochistlán

Abstract

The objective of this article is to determine the number of combatants in the Mixtón War (1541–42), one of the most important military confrontations of the early years of the vice-royalty in Western Mexico, by analysing the Peñol de Nochistlán. To this end, information provided by historians has been compared with the population estimates established from the density of settlements known from archaeological evidence in order to define the area occupied by the armies involved in the conflict. This exercise resulted in a shifting array of spaces that could have been used by the combatants during confrontations. However, it will enable more intense archaeological prospecting in the area around the site of El Tuiche — the place identified as the Peñol of Nochistlán — revealing new evidence of the events that occurred on this battlefield.     

WHAT ATTRACTS KNOWLEDGE WORKERS? THE ROLE OF SPACE AND SOCIAL NETWORKS

The aim of this paper is to identify the determinants of the geographical mobility of skilled individuals, such as inventors, across European regions. Among a large number of variables, we focus on the role of social proximity between inventors’ communities. We use a control function approach to address the endogenous nature of networks, and zero‐inflated negative binomial models to accommodate our estimations to the count nature of the dependent variable and the high number of zeros it contains. Our results highlight the importance of physical proximity, job opportunities, social networks, as well as other relational variables in mediating this phenomenon.     

The Augustan Temple and Forum of the Colony of Barcino: A 90 Degree Turn

The Augustan Roman temple at Barcino has been a key element during the last 60 years in the research of the colony's urban development. Its peculiar elongated and narrow plan, first proposed in 1835, and its location at the highest point of the ancient city have dictated our understanding of the urban layout of Barcino by conditioning the shape of the city's forum and affecting the interpretation of the archaeological excavations carried out in the area since then. This paper proposes an alternative plan of the temple, based on data drawn from recent archaeological excavations, topographical analysis, typological comparisons, and the study of written sources. Our alternative hypothesis for the temple permits an in‐depth reinterpretation of the plan of the forum and the evolution of the urban plan.     

Evolution of Innovation Policy in Emilia-Romagna and Valencia: Similar Reality,Similar Results?

This paper examines the evolution of regional innovation policy in Emilia-Romagna and Valencia, two regions with similar economic features that implemented close innovation policies in the 1970s and 1980s. We investigate whether their similarities have led to parallel targets, policy tools and governance developments. We show that innovation policy in both regions suffered from the effects of privatization, budget constraints and changes to manufacturing during the 1990s and we highlight the consequences. Although Emilia-Romagna experienced deeper changes to its innovation policy, privatizations and/or the replacement of public funds promoted commercial approaches and induced market failures in both regions. The worst effects of these policies were the implementation of less-risky innovation projects, the shift towards extra-regional projects and markets, and the favouring of large firms.     

La retórica bajo el barniz de la lógica: Samuel Ramos y su discurso sobre la inferioridad mexicana

Samuel Ramos reflects on the essence of the Mexican people in the philosophical essay El perfil del hombre y la cultura en México (1934). He emphasizes the sentiment of inferiority and the desire to hide this inferiority by camouflage strategies as a distinctive characteristic of the Mexican. This analysis of Ramos's Perfil unveils a discrepancy between the form that the author imitates—the scientific treatise—and the true argumentative constitution of his text—the rhetorical discourse. Along with the anti-rhetoric position of the rationalists, Ramos considers rhetorical argumentation as an inferior approach that has to be dissimulated and hidden under a layer of science.     

Le Socialisme français en crise

This article analyses the gravity and reasons for the crisis currently affecting the French Socialist Party. Going beyond the electoral disasters of 2014, it situates this crisis within the context of the destabilisation of the French party system due to growing divisions on the left and on the right caused by the evolution of the European Union in the current context of economic crisis. The left/right cleavage that structures the functioning of the political system is being called into question by an alternative cleavage that increasingly opposes the supporters of European integration against their opponents. The cross-cutting nature of these two cleavages will henceforth prevent the left from uniting on a programme of government. Within the Socialist Party itself this phenomenon is a factor of serious division and, as a result, makes the government's parliamentary base more fragile. It further deepens the long-standing differences on economic policy because of the explicit choice made by the Socialist government in favour of a supply-side approach. The Socialist Party seems to have arrived at the end of a political cycle where it will have to make choices that it has postponed for many years, with the risk of breaking up and with the threat of starting an electoral and political decline that could ultimately deprive it of its status as a party of government.
