Human occupation in South America by 20,000 BC: the Toca da Tira Peia site,Piauí, Brazil

When and how did the first human beings settle in the American continent? Numerous data, from archaeological researches as well as from palaeogenetics, anthropological and environmental studies, have led to partially contradictory interpretations in recent years, often because of the lack of a reliable chronological framework. The present study contributes to the establishment of such a framework using luminescence techniques to date a Brazilian archaeological site, the Toca da Tira Peia. It constitutes an exemplary case study: all our observations and measurements tend to prove the good integrity of the site and the anthropological nature of the artifacts and we are confident in the accuracy of the luminescence dating results. All these points underline the importance of the Toca da Tira Peia. The results bring new pieces of evidence of a human presence in the north-east of Brazil as early as 20,000 BC. The Toca da Tira Peia thus contributes to the rewriting of the history of the peopling of the American continent.     

Functional insights into the innovative Early Howiesons Poort technology at Diepkloof Rock Shelter (Western Cape,South Africa)

The Howiesons Poort (‘HP’) is characterized by a set of technological innovations that mark a rupture in the Southern African Middle Stone Age. However perspectives regarding its origin and emergence remain speculative. The recent identification of an Early HP phase at Diepkloof Rock Shelter provides the opportunity to characterize the initial stage of this technology and to discuss various mechanisms behind its innovative characteristics.     

Community Collaboration and Other Good Intentions

Collaborative and community-based archaeological research encompasses a broad spectrum of approaches; however, there are often discrepancies between how researchers ‘sell’ the collaborative endeavour in theory and how it is actually practised. Over the past several years, I have had the opportunity to participate in several projects, ranging from those that claimed to be ‘truly collaborative,’ to research that maybe should have asked, ‘what community?’ These experiences raised difficult and disturbing questions concerning the nature and practice of collaborative and community-based archaeology. In this paper, I confront these issues as I have experienced them personally. While community-based practices aim to redress a historical and ongoing power imbalance between the researcher and the researched, constant vigilance is required lest the ‘good intentions’ of anthropologists inadvertently mask an exploitation that may be inherent in the structure of research itself. In considering the corporate nature of academia, I query whether the collaborative research model represents a break with the past, or is instead simply the same old practice dressed up in fashionable new language.     

Life Sciences in the Netherlands: Weakness in a Strong National Policy

The Netherlands is an example of a European country in which the commercialization of knowledge is hampered by a somewhat risk-averse culture at universities and a shortage of venture capital for early growth of start-up firms. This article addresses the policy programme in the Netherlands to improve the situation for the life sciences since the early 2000s. The target number of newly established firms could easily be achieved and the programme was able to improve the business climate for new firm establishment. However, the programme could not improve conditions for growth of new firms because it could not achieve a comprehensive turn in the business climate, due to the short cycle-time of the programme (4–5 years). In addition, the programme did not take advantage of existing critical mass in the largest cluster or from any other competitive strength of particular clusters. These circumstances were influencing a relatively large number of small and vulnerable firms. The article concludes with a set of insights from which lessons can be drawn.     

Narrative strategies in a nondemocratic setting: Moscow’s urban policy debates

The Narrative Policy Framework (NPF) explains the role of narratives in policy processes. The NPF was developed for democratic contexts and has not been systematically applied in a nondemocratic setting. This study fills this gap with an empirical analysis of narrative strategies used by governmental and oppositional actors in urban policy debates in Moscow. Results show how governmental actors consistently use angel shifts, contain issues, and avoid using causal mechanisms, while actors opposing governmental policy use devil shifts, expand issues, and use intentional causal mechanisms. The findings suggest that narrative strategies differ depending on whether policy actors seek to promote policy reforms or draw attention to problems. We argue that policy actors’ objectives are a well-suited predictor for narrative strategies in both democratic and nondemocratic contexts.     

Nationalism,populism or peopleism? Clarifying the distinction through a two-dimensional lens

Prompted by recent scholarly debates on the distinction between populism and nationalism, we elaborate on the Laclaudian understanding of populism as an antagonistic form of us-building/community-making that relies on the extension of equivalential chains between demands. From this heuristic perspective, populism can be understood as an empty form to be filled with different contents, such as nationalism. Our radically anti-essentialist stance combines Laclau's formalist conceptualisation of populism and Brubaker's work on nationalism. We highlight the ontological dimension of populism, as a form of us-building, and the ontic dimension, as an array of discursive repertoires that fill the form, such as ‘the people’ for peopleism. We explore the ontological–ontic distinction through the case of Narodism in Serbia. Conceptualising populism two-dimensionally contributes both to debates on the ‘core’ of populism and to cases where articulations of ‘the people’ coincide with expressions of nationhood, civilisationalism and culturalism, rather than being entirely the same.     

Seismic Assessment of a Monumental Building through Nonlinear Analyses of a 3D Solid Model

ABSTRACT

The paper analyzes the static behavior and the seismic vulnerability of the “San Francesco ad Alto” building in Ancona (Italy), which is currently used as a Regional Headquarter of the Marche Region by the Italian Army and was formerly a monastery. The global static structural behavior and the dynamic properties have been evaluated using the Finite Element modeling technique, in which the nonlinear behavior of masonry has been taken into account by proper constitutive laws. The concepts of homogenized material and smeared cracking are used to evaluate the capacity of the monastery to withstand lateral loads together with the expected demands resulting from seismic actions (N2 method), using a nonlinear static analysis (pushover). The comparison of seismic demand and capacity confirms the susceptibility of these types of buildings to extensive damage and collapse, as frequently observed in similar buildings. This paper aims to point out that advanced numerical analyses can offer significant information on the understanding of the actual structural behavior of historical buildings. It is believed that the methodology and the overall conclusions of this case study are valid for many historical monasteries in Europe.     

The impacts of spatial planning on the sustainable territorial development of the Rhine-Danube Trans-European Transport Corridor through Serbia

The Danube River is both the international waterway E-80 and the Rhine-Danube Core Network Corridor of nine European corridors in the trans-European transport network, and it is the core area of the most significant Danubian development axis in the Republic of Serbia. The present research focus of this paper is the integrated impact of spatial planning on achieving the sustainable territorial development of the Rhine-Danube Corridor through Serbia and its potential transboundary impact. Integrated assessment (environmental and social), based on the combined application of the standard strategic environmental assessment (SEA) method and the newly presented adapted strategic environmental assessment (ASEA) method, has made it possible to predict the effects of future activities on the sustainable territorial development of the waterway corridor, not only in Serbia, but also in other Danubian countries. The applied combination of the SEA and ASEA methods is presented in the form of key planning solutions in three selected sectors: international inland waterway, water management infrastructure and tourism. The results indicate that the negative impacts of potential conflicts between the planning solutions are far greater than the negative impacts of individual planning solutions, and that it is more difficult to control and mitigate or neutralize them.
