SPARK: Strategic Planning Approach for Resilience Keeping

In a world in growing turbulence, complexity and uncertainty, where crisis is becoming the norm rather than the exception, resilience is increasingly seen as a critical feature that reflects the capacity of a system to absorb disturbance and reorganize without collapsing. Resilient systems are more adaptable to change, are more able to learn and are less vulnerable to disturbance and external shocks (e.g. natural phenomena, economic crises or political shifts). The resilience theories are re-emerging as a field of research and practice with application to socio-ecological systems, fostering new insights in the discussions about sustainable development. The main purpose of this paper is to explore resilience as a concept and as a framework for promoting more sustainable trajectories, highlighting its potentialities and advantages for policy and planning processes. SPARK, or the strategic planning approach for resilience keeping is introduced in the paper as a new sustainability framework, following key underlying concepts and seven key principles that capture the essence of resilience theories. The paper advances a methodological concept proposal for resilience assessment and planning that aims to contribute to linking theory and practice, performing knowledge brokerage and enhancing policy learning.     

Fertility decline in rural China: a comparative analysis

Many models have been proposed to explain both the rapidity of China's fertility decline after the 1960s and the differential timing of the decline in different places. In particular, scholars argue over whether deliberate policies of fertility control, institutional changes, or general modernization factors contribute most to changes in fertility behavior. Here the authors adopt an ethnographically grounded behavioral-institutional approach to analyze qualitative and quantitative data from three different rural settings: Xiaoshan County in Zhejiang (East China), Ci County in Hebei, (North China), and Yingde County in Guangdong (South China). The authors show that no one set of factors explain differential timing by a combination of differences in social-cultural environments (e.g. spread of education, reproductive ideologies, and gender relations) and politico-economic conditions (e.g. economic development, birth planning campaigns, and collective systems of labor organization) during the early phases of the fertility decline.     

A Multidisciplinary Approach to the Study of Archaeological Mortars from the Town of Ammaia in the Roman Province of Lusitania (Portugal)

The Roman town of Ammaia (in Marvão Region) is considered one of the most important recent findings of the Roman presence in Portuguese territory. It was settled in Republican times and abandoned in the seventh century. In this research, 17 masonry mortars and renders from the West Tower (South Gate), the residential area near the West Tower, the macellum, the peristylium, the public bath building, the podium of the temple and the portico of the forum were analysed. The methodology of chemical, mineralogical and microstructural characterization has involved several complementary techniques, including stereomicroscopy, X‐ray diffraction, thermal analysis and scanning electron microscopy coupled with energy‐dispersive X‐ray spectroscopy. The results indicate that the mortars from the beginning of the town's edification were mainly composed of soil (clays). Later, during the main Roman building period, mortars were composed using a calcitic binder and the mortar composition varied according to their use and function. The samples from a period subsequent to the Roman occupation are based on a dolomitic binder. From the present study, relevant information has been acquired about the technological evolution of Roman construction in Ammaia, the historical context of the archaeological structures and guidelines for the conservation and restoration of mortars.     

Bronze production in Southwestern Iberian Peninsula: the Late Bronze Age metallurgical workshop from Entre Águas 5 (Portugal)

Archaeological works at Entre Águas 5 (Portugal) uncovered a seasonal LBA settlement with significant metallurgical remains (crucibles, moulds, prills and a tuyere) related to bronze production. Radiocarbon dating ascribes an occupation period (10th–9th century BC) previous to Phoenician establishment in Southwestern Iberia. In spite of the proliferation of metal artefacts during LBA, the production of bronze alloys is still poorly understood. An integrated analytical approach (EDXRF, optical microscopy, SEM–EDS, micro-EDXRF and Vickers microhardness) was used to characterise this metallurgy. Crucibles show immature slags with copious copper nodules, displaying variable tin content (c. 0–26 wt.%), low iron amount (<0.05 wt.%) and different cooling rates. Certain evidences point to direct reduction of oxide copper ores with cassiterite. Scorched moulds with residues of copper and tin indicate local casting of artefacts. Finished artefacts also recovered at the site have an analogous composition (bronze with ∼10 wt.% Sn and low amounts of Pb, As and Fe) typical of coeval metallurgy in SW Iberia. Some artefacts reveal a relationship between typology and composition or manufacture: a higher tin content for a golden coloured ring or absence of the final hammering for a bracelet. An uncommon gilded nail (gold foil c. 140 μm thick; 11.6 wt.% Ag; ∼1 wt.% Cu) attests the existence of evolved prestige typologies. This LBA settlement discloses a domestic metallurgy whose main features are typical in Iberian Peninsula. Finally, it should be emphasized that a collection as comprehensive and representative of a single workshop has rarely been studied, enabling a deeper understanding of the various operations involving the bronze production and manufacture of artefacts.     

Closed Condominiums as Urban Fragments of the Contemporary City

Contemporary cities have witnessed the emergence of new real-estate products in which gated communities and closed condominiums (CCs) can be included. The proliferation of these urban products is worldwide, with similar patterns that are analysed in this paper according to five perspectives of analysis: physical, economic, social, political and cultural. These perspectives cross-cut some of the main issues of discussion of the contemporary urban debate associated with private residential developments. These developments seem to appeal to an increasing number of social groups and have been able to adapt to different planning systems. With a smaller scale, these developments emerged in Portugal in the form of CCs, and are analysed in a case study in Greater Oporto. The purpose of this paper is to present the Portuguese singularities of this phenomenon in comparison with the worldwide dimension. In our case study we find some important particularities strongly associated with the Portuguese planning system. Some of these particularities have negative impacts on the surrounding urban landscape. As a result, CCs demand specific planning policies to counteract the negative consequences they are likely to generate in local social and urban fabrics. In the absence of these policies, CCs, as well as other private residential developments, are likely to contribute further to an increasingly fragmented and divided urban landscape.     

Early Neolithic funerary diversity and mitochondrial variability of two Iberian sites

An analysis of the burial characteristics of the individuals recovered from two Early Neolithic sites in Navarre (Los Cascajos and Paternanbidea), in the Spanish Basque Country, revealed a complex funerary ritual. The individuals recovered from the Paternanbidea site were distributed in three double graves and a multiple one, while the individuals from Los Cascajos were buried in individual pit-shaped tombs; furthermore, the tombs had a variety of cultural and funerary features. The aim of this study is to evaluate the burial ritual by means of mitochondrial DNA data and the funerary characteristics of 36 individuals recovered from these two sites. The results show that the diversity of these Early Neolithic burial practices from the northern Iberian Peninsula cannot be explained by means of maternal kinship relationships.     

Crossed gazes over an old city: photography and the ‘Experientiation’ of a heritage place

Abstract

The paper analyses a group of photographs of the old city of Porto, a UNESCO World Heritage Site. The photograph is used as a medium to elicit the ways different social agents experience and relate to Old Porto as a heritage place. The photographs were collected as part of a wider research project on the way sense of place of Porto’s old city was differentially constructed by local inhabitants, tourists and the City Council. Illustrated postcards were also analysed. The findings demonstrate the usefulness of this particular form of image-based ethnographic research in understanding the forms in relation to a heritage lived-in place.     

Evidence of contact between New and Old World: paleoparasitological and food remains study in the Tagus river population of Sarilhos Grandes (Montijo,Portugal)

The period of European maritime expansion that started in the fifteenth century had a great impact on trading, on human migrations and consequently in the dispersion of infectious diseases. Portugal was at the core of this expansion; however, studies about parasitic infections, especially helminths, are lacking. This study aims to help reduce this gap presenting the results of microscopic analysis of soil sediments collected from the São Jorge churchyard of Sarilhos Grandes (Montijo). Consecrated in the fourteenth century AD, it remained as a burial ground until the nineteenth century. Soil samples collected from the pelvic girdle of five adult individuals and samples taken as control were analysed under the microscope after current conventional methodological procedures were undertaken. Eggs from Ascaris lumbricoides were identified. Also eggs of trichostrongyle type species were identified in two individuals and may represent the first report in archaeological European samples. Food remains include potato and rice starches, muscle fibres, bivalves, pollen grains and fungi spores. The stratigraphy interpretation together with potato findings put the oldest skeletons to a chronology around the sixteenth century AD. These results are consistent with historical sources that documented the prominence of Tagus river nearby villages in maritime expansion.     

Urban Regeneration in the Brazilian urban policy agenda

This article aims to highlight the main arguments that sought to justify the incorporation and legitimization of Urban Regeneration in the urban policy agenda in Brazil. It shows how the convergence between different and even conflicting propositions related to urban development provided ideological support to the construction of discourses in which urban regeneration is portrayed as beneficial to society as a whole, and how recent international ideas on urban development were incorporated in urban policies of contemporary Brazil, considering our local socio-economic and political environment, planning tradition and regulatory frameworks. The focus will be on Rio de Janeiro and particularly São Paulo given the key role these two cities play in defining urban policy paradigms, guiding government agendas and exporting regulatory models to other parts of Brazil.
