Inclusive growth from an urban perspective: a challenge for the metropolis of the twenty-first century

This paper addresses the study of inclusive growth from an urban perspective. It proposes to focus the relationship between urban economic growth and income distribution in cities in which manufacturing production and external demand play a central role. Opposed to the literature that considers economic growth leads to an increase in inequality in income distribution, we present some operative economic tools from Marshallian Industrial Districts theory and from urban economic theory with which to develop an economic strategy for inclusive urban growth, making possible to achieve simultaneously economic growth and improvements in income distribution. An interesting example of a metropolis with a dynamic of economic and employment growth compatible with a reduction in income inequality is provided by Barcelona. This metropolis disposes a Survey of living conditions and habits of the population since 1986 that allows an analysis in terms of inclusive urban growth.     

Costs and benefits of environmental change: tourism industry's responses in Arctic Finland

ABSTRACT

Recent research has focused on the impacts of environmental change to tourism. In particular, the perceived costs of climate change have been increasingly studied. However, the relationship between costs and benefits resulting from the changing environmental conditions for the industry has been less examined. This paper identifies the locally observed changes in the natural and socio-economic environments and aims to analyse the financial costs and benefits to tourism businesses in two tourism-dependent communities in northern Finland. The specific focus is on adaptation and adaptive management in a tourist destination scale. Adaption is understood as an investment creating not only implementation costs, but potentially also benefits for tourism operations. Research materials were collected among tourism and tourism-related businesses through 41 semi-structured thematic interviews. Results indicate that the evaluated benefits of environmental change seem to exceed those of costs. This conforms to the on-going discourse of climate change–tourism relations associated with the Arctic region where both awareness and vulnerability to change are considered relatively high but the level of responses, i.e. adaptation, low. These results can help to further identify the most vulnerable sectors in tourism and assist entrepreneurs preparing for environmental and climate change. However, the paper concludes that while global environmental change, with specific adaptive management strategies, may create local short-term direct benefits for the industry, a long-term sustainability of tourism in the Arctic calls for mitigation responses to climate change.     

Seismic performance of historical vaulted adobe constructions: a numerical case study from Yazd,Iran

Past earthquakes have demonstrated that historical vaulted adobe buildings are highly vulnerable to seismic actions. Hence, it is crucial for such building typologies to be evaluated in terms of seismic capacity. To this end, this article deals with the seismic performance of historical vaulted adobe houses from the city of Yazd, Iran as one of the seismically active areas of the world and possessing a very rich adobe heritage. Thus, and based on a detailed geometrical survey, a representative sample of adobe houses from Yazd was studied using a simplified in-plane analysis based on three geometric indexes. Concerning the out-of-plane behavior, a deeper assessment was conducted by performing a numerical study, where the main influential parameters on the seismic behavior of vaulted adobe buildings were considered. The numerical analyses were carried out by adopting the limit analysis theory implemented in the Block2D software. The results obtained indicate the safe in-plane behavior of most of the houses and the safe out-of-plane response of the sample under gravitational loads. However, the sample out-of-plane safety under earthquake-induced loads seems to be a matter of concern.     

Kinetic effect of carbonic anhydrase enzyme on the carbonation reaction of lime mortar

The effect of carbonic anhydrase enzyme on the precipitation kinetics and phase transformations of calcium carbonate, and on the strength development of lime mortars has been investigated with saturated lime solutions, lime pastes and lime mortars under atmospheric conditions. The results clearly show that carbonic anhydrase catalyzes the reaction between carbon dioxide and aqueous lime, and increases the rate of calcium carbonate crystallization, the yield of the carbonation reaction and mortar strength at early ages. This is most likely a kinetic effect associated with the increased rate of carbonate ions supply to the solution by the enzyme. In addition, this enzyme favors the formation of stable calcite and significantly modifies its morphology by developing new crystal faces. These results suggest a novel approach for accelerating the hardening of lime mortars using carbonic anhydrase enzyme, which may offer a potentially novel approach with significant benefits on the applications of lime mortars in architectural heritage conservation as well as in construction.     

Building survey forms for heterogeneous urban areas in seismically hazardous zones. Application to the historical center of Valparaíso,Chile

ABSTRACT

Building survey is an essential data-collection procedure to feed large-scale seismic vulnerability assessment. The available strategies usually consider survey forms to gather information about the urban buildings. The application of the available survey forms poses important challenges for the case of the heterogeneous urban centers including different structural typologies. This work proposes four specific survey forms for traditional structural typologies constructed with masonry, reinforced concrete, mixed steel-reinforced concrete, and timber. The proposed forms request essential information on the parameters necessary for seismic vulnerability assessment, by evaluating the lateral-load resistant system, regularity, condition of conservation, and existing damages. The survey forms were applied to the study of 111 buildings of the historical center of Valparaíso, Chile. The proposed methodology was complemented with the use of Geographic Information Systems to obtain a complete database with the structural characterization of the most representative typologies for future works of large-scale seismic vulnerability assessment.     

Dietary patterns in human populations from northwest Patagonia during Holocene: an approach using Binford’s frames of reference and Bayesian isotope mixing models

The goal of this paper is to assess the variation in the proportional contribution of diverse resources to the diet of human populations from northwest Patagonia (Argentina) throughout the Middle-Late Holocene. Particularly, we assessed the variation among three geographic areas and two periods. We first estimated the expected proportions of terrestrial animals and plants and aquatic resources for each area according to the Binford’s frames of references approach. A Bayesian mixing method was then applied to calculate the proportion of plants and animals in the diets from stable isotopes (δ¹³C and δ¹⁵N) of human bone collagen. The isotope values suggest that the composition of diets differed spatially and temporally. Diets of South Mendoza were mainly composed of terrestrial animals (Rhea-Lama and rodents) with a greater incorporation of C₃ plants towards the later Late Holocene; in North Neuquén, Rhea and Lama represent a proportion of 0.84 of the diet consumed; and finally, the sample of Center Neuquén is the only one with high values of Araucaria in the diet. The isotopic values obtained for the three studied areas did not fit to the expectations of Binford’s model, North Neuquén being the area that departs most from the predicted proportions of terrestrial animals and plants and aquatic organisms in the diet. These findings open up new questions about the local conditions that influenced regional variation in the diet of prehistoric hunter-gatherers.     

Rethinking the metaphor of light: María Zambrano in dialogue with Jacques Derrida and Hans Blumenberg

ABSTRACT

The notion of metaphor has been broadly discussed during the twentieth century as an essential and necessary part of language and history. This article examines the theoretical dialogue that links the centrality of the metaphor of light in the work of María Zambrano with reflections on this topic by Jacques Derrida and Hans Blumenberg. Through various formulations of this metaphor across different works, Zambrano presents the metaphor linked to poetic reason as not reducible to a mere rhetorical ornament or to a concept. By articulating alternative metaphors to the imperative of clarity as the blinding light of Occidental reason, Zambrano introduces a solid critique to rationalism and introduces the metaphor of the Dawn as a new form of knowledge. This new intonation of the metaphor of light opens up an unexplored direction in Spanish thought not only by thinking the metaphor of light through poetic reason and its critique to the philosophical tradition, but also by assuming the political implications of this metaphor and criticizing its heliopolitical configuration. Indeed, Zambrano states the significance of the metaphor of the sun linked to the sacrificial structure of history, particularly of Spain, and its necessary overcoming as the possibility of a radical democracy.     

Megaliths, Agriculture, and Social Complexity: A Diet Study of Two Swedish Megalith Populations

This paper tests the relationship between the erection of megaliths and agriculture in Neolithic Scandinavia. A dietary change in two Swedish megalith populations was tested by analyses of stable carbon and nitrogen isotopes extracted from human bone collagen. Carbon isotopes show that marine resources still were utilized in the coastal area and nitrogen isotope indicates that the major part of the protein came from a high trophic level, i.e., animals. It is concluded that a change in diet, and hence subsistence, took place from a hunter—gatherer-based subsistence toward one based on pastoralism, not horticulturalism. The prerequisite for social complexity is discussed and the author favors sedentism as the major determinant.
