The benefits of urban open spaces for improving the quality of life and sustainability in cities are widely recognized. The functions they perform within the framework established by urban planning, as well as their metrics, are now more complex than in the past. It is convenient to develop methodologies for the evaluation of these spaces adapted to the present time to check their level of efficiency, which is useful in urban planning for the establishment of new urban open spaces. The aim of this study is to classify such spaces through a methodology that integrates spatial analysis, configuration analysis, and decision support so as to understand their complexity from a more advanced analytical perspective. In order to do this, a prior exploration of specific literature is carried out, which allows the characterization of the functions of urban open spaces by means of the corresponding analysis variables in a weighted manner. The integrated combination of these advanced tools is a step forward in achieving consistent and detailed results for urban open spaces. They perform their functions best in dense, central, equipped, accessible, connected, and easily walkable urban environments. In addition, future recommendations are provided.  相似文献

This article presents the life stories of six indigenous women from the Amazonian region, who coordinate local women processes through indigenous organizations and networks. Since the political and legal visibility of violence against indigenous women in Colombia is weak and limited, we aim to analyze their experiences from an intersectional perspective. For this purpose, we employed multiple methodologies, including body mapping and social cartography. Thus, by reconstructing their experiences and attempts to make visible violence against them, we could perceive some of its multiple modalities, which are quickly captured by the great category.  相似文献

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes.  相似文献

Zusammenfassung  Regionale Entwicklungsstrategien werden in der Regel ohne substanzielle Beteiligung der Wirtschaft entwickelt. Das war im Projekt „Zukunft Ruhr 2030“ anders. Hier hat der „Initiativkreis Ruhrgebiet“, die Vereinigung gro?er Unternehmen in der Metropolregion Ruhr, Entwicklungsperspektiven für die Region aus Sicht der Wirtschaft entworfen. Sechs führende Unternehmensberatungen haben in Zusammenarbeit mit Experten aus Wissenschaft und Wirtschaft verschiedene Themenfelder untersucht, eine Vision entwickelt und daraus eine Entwicklungsstrategie für die kommenden Jahre abgeleitet.  相似文献
