Minimum Thrust of Rounded Cross Vaults

This study analyzes the static behavior of the rounded cross vaults based on the limit analysis approach developed for masonry structures and adopts a rigid no-tension constitutive model with no sliding. The kinematic theorem of the limit analysis with a compatible tridimensional mechanism is applied on these structures with the aim of evaluating the minimum thrust. In this way it was possible to build some abaci in which the ratio between the minimum thrust and the weight is plotted versus the geometrical characteristics of the vaults. Finally, the proposed abaci are used to calculate the thrust of the main vault of the Diocletian Baths in Rome.     

Measuring the impact of the European Capital of Culture programme on overnight stays: evidence for the last two decades

This study explores the effects of the European Capital of Culture (ECoC) on tourism demand, measured as overnight stays, for the years 1998–2014. The analysis includes 34 ECoC hosts and makes use of data on approximately 800 European cities. A difference-in-differences propensity score matching estimator shows that hosting the ECoC leads to an increase in overnight stays of 8% on average during the year of the event but does not stimulate tourism demand in subsequent years. To account for deviations in the distribution of tourism inflows between ECoC and other cities, the quantile difference-in-differences estimator is used. This leads to similar but somewhat stronger results, especially for the year of the event and for the year after. Separate estimations of ECoC hosts reveal that there is a certain degree of heterogeneity in the effect. Long-term impacts can only be observed for a small group of cities (Essen, Guimarães, Salamanca and Tallinn).     

International mediation and Australian foreign policy: building institutional capacity to respond to overseas conflict

In October 2012, Australia's parliamentary Joint Standing Committee on Foreign Affairs, Defence and Trade recommended that a mediation support unit should be created within the Australian Agency for International Development, a department now amalgamated with the Department of Foreign Affairs and Trade. The question is: Does Australia possess the motivation and capacity to implement active and effective international mediation by building the capacity of intermediaries to deploy various peacemaking methods to hasten de-escalation at different stages of a conflict? If not, is a mediation support unit an appropriate initiative to address this capability gap? This article draws on quantitative conflict data sets and an expert panel to conclude that Australia's track record demonstrates significant capacity to undertake international mediation, but that the mediation personnel and processes available to government are insufficiently resourced and coordinated to readily provide policymakers with accessible tools to undertake the diverse range of mediation strategies advocated by conflict scholars. While a mediation support unit would address some of these issues, at present it conflicts with the Department of Foreign Affairs and Trade's institutional philosophy based on diffused expertise.     

From productivism to post-productivism … and back again? Exploring the (un)changed natural and mental landscapes of European agriculture

This paper has evolved out of a growing dissatisfaction with the relatively uncritical acceptance in contemporary debates that agriculture in advanced societies has moved from 'productivism' to 'post-productivism'. A brief review of current conceptualizations of productivist and post-productivist agricultural regimes reveals inconsistencies in current understandings these dualistic terms. The problem has partly been that the conceptual literature on post-productivism has largely failed to take into account the wealth of actor-oriented and behaviourally grounded research. Productivist and post-productivist agricultural regimes have also been conceptualized from a UK-centric perspective that has largely failed to discuss whether the concept has wider applicability within Europe and beyond. The paper discusses the time-lag and spatial inconsistencies in the adoption of post-productivist action and thought, and emphasizes that different localities are positioned at different points in a temporal, spatial and conceptual transition from 'pre-productivist' to 'post-productivist' agricultural regimes. The notion of the 'territorialization' of productivist and post-productivist actor spaces highlights the wide-ranging diversity that exists within the productivist/post-productivist spectrum, and that productivist and post-productivist action and thought occurs in multidimensional coexistence leads one to question the implied directionality of the traditional productivist/post-productivist debate. It is suggested that the notion of a 'multifunctional agricultural regime' better encapsulates the diversity, non-linearity and spatial heterogeneity that can currently be observed in modern agriculture and rural society.     

THE SPACES OF NATURE: INTRODUCTION

The articles in this section aim at critical reappraisal of space from the viewpoint of the materiality of human action which is underpinned by a special focus on its dealings with nature. Space is primarily viewed by others than geographers and/or from outside Scandinavian and Anglo‐American research. The role of language and culture, as well as using the possibilities of ecosemiotics grown out of the Tartu–Moscow school, is highlighted in an attempt to enliven discussions of lived space and human relationships with nature.     

Applying the Strategic‐Relational Approach to Urban Political Ecology: The Water Management Problems of the Baixada Fluminense,Rio de Janeiro,Brazil

Abstract: The complexity of water management requires an explanatory framework that is able to capture the multidimensionality of the relations between nature and society increasingly mediated by the state. The evolution of water problems in the Baixada Fluminense, a wetland area situated to the north of Rio de Janeiro, provides a paradigmatic example of how water management becomes incorporated into the fluid politics between state, nature and society. The local experience is examined by making use of the strategic‐relational approach (after Bob Jessop) expanded to urban political ecology. The concept of “trialectics” is proposed as an ontological representation of the interconnections between the state apparatus, class‐based relations and the socionatural elements of the water cycle. The empirical results show that, in a situation of precarious water supply, regular flooding and severe river degradation, state interventions have tended to favour certain groups and areas, which only intensifies the politicisation of water management.     

THE EPISTEMIC AND MORAL ROLE OF TESTIMONY1

My aim in this article is to provide a critical‐productive appreciation of witness testimony that avoids the false and crooked dichotomies that pervade contemporary philosophy of history and historical theory. My specific, pragmatist approach combines the recent accounts of Hayden White about “witness literature” with the “generative‐performative” consideration of testimony by Martin Kusch. The purpose is to appreciate, in a non‐foundationalist way, the epistemic and moral role of testimony in the constitution of the representation of the recent past. To achieve this I examine the assumed epistemic and political privilege of the testimonies of survivors of state terrorism from the recent past, and I draw on insights of three of the most relevant survivor witnesses: Primo Levi, Victor Klemperer, and Pilar Calveiro. The essay tries to avoid both an epistemic and a moral posture based on something like “the privileged victim's perspective,” and instead approaches the specific analysis of production and circulation of witness discourse in terms of its contribution to the constitution of the past. That is, it recommends that one look at witness testimony not as an attempt to return to the past but as an action in the present. The result in so doing is to follow some recent results discussed in the new epistemology of witness testimony, which insist that: first, trust in testimony is an irreducible function of the acceptance of knowledge (this means that testimonies should not be treated as secondary sources of knowledge or as parasitical on experience and reason); and second, the production‐circulation of testimonies does not function only in the context of justification but is also legitimately constitutive of knowledge.     

THE CRISIS OF CULTURE AND THE CULTURE OF CRISIS

“Crisis” in cultural policy is a widespread phenomenon, whose meaning can be exemplified in case of opera. The Berlin, Paris and London opera houses hit a crisis at the end of the twentieth century. At the core of these crises and the discussions surrounding them were funding problems – which were also a point of academic interest. But beyond that, opera seemed to be an arena of discourse where creeping conflicts in the political system and society were debated as fundamental crises of a most cherished cultural heritage. This paper examines how, in these cases, “crisis” proves to be a cultural phenomenon in itself, displaying a symbolic and functional character rather than being defined by references to specific matters and qualities.     

Towards a holistic approach to heritage values: a multidisciplinary and cosmopolitan approach

ABSTRACT

In this paper, we explore the ‘Preservation/Heritage Values/Management’ triptych, and we propose a new method for addressing the values attributed to cultural heritage sites. Combining multidisciplinary and cosmopolitan approaches, we propose a way of moving beyond the traditional lens of assessing significance within the imposed categorical framework of ‘aesthetic, historic, scientific, social or spiritual values’. We provide an example of our new approach through a worked case study in the Maloti-Drakensberg Park World Heritage Site (South African section). Our case study concerns the values associated with the world famous San (Bushman) rock art of this mountain area. Through a thematic analysis of data collected in this area from 2009 to 2017, six cross-cultural interest points are identified and are discussed. Building upon the history of values-based heritage management, we argue that our multidisciplinary and cosmopolitan method is transferable and can be applied to heritage sites around the world. It can facilitate the construction of heritage management plans that are more in tune with local actors and that will therefore prove to be more effective and sustainable.     

Constructing places for the market: The case of Newcastle,NSW

Abstract

Cities with a heritage of heavy industry, such as Newcastle (NSW), face an insecure future as they undergo economic restructuring. The identities of cities are being refashioned by entrepreneurial urban governments, as part of a three‐pronged attempt to market their territories. A social construction approach reveals the problematic nature of these symbolic reconstructions, their partiality, the reduction of heritage to a commodity, and the eliding of socio‐economic disadvantage. The new post‐industrial identity for Newcastle disinherits working people, ignores the local indigenous peoples, and trivialises the role of women. The richly layered urban landscape and historically constructed narratives – the local heritage – have been cynically appropriated and transformed for the purposes of place marketing. The rhetoric of post‐industrialism conceals poverty and alienation, and the associated physical restructurings are displacing service‐dependent populations.
