Spatial Patterns in the Association between the Prevalence of Asthma and Determinants of Health

The World Health Organization endorses the study of diseases from the perspective of the Determinants of Health (DH), that is, the circumstances in which people are born and raised, the environment in which they grow up and age and their lifestyle. The aim of this study is to analyze the spatial behavior of the prevalence of asthma in Aragon, a Mediterranean region in Spain, under the DH approach. The methodological process entailed building a spatial database collating asthma prevalence as dependent variable, and lifestyle, socioeconomic, and climate indicators as explanatory factors, and then evaluating the spatial variability of the relationships by combining the Principal Component Analysis (PCA), Multiscale Geographically Weighted Regression (MGWR) models and cartographic design techniques. MGWR evidenced spatially varying relationships operating at different scales. Lifestyles seem closely tied to the prevalence of asthma in most of the study area while urban functionality and local climate patterns seem to boost prevalence rates in some specific enclaves. Consequently, the social and environmental conditions that characterize the study area translate into several DH scenarios modulating the spatial distribution of asthma. This differential DH behavior detected by local regression models is relevant to guiding and refining public health decision-making.     

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.     

Characterization of prehispanic cosmetics found in a burial of the ancient city of Teotihuacan (Mexico)

The present paper reports the chemical data obtained on samples of pigmenting materials contained in 31 miniature vessels found in a burial found in Teopancazco, a multiethnic neighborhood center located in the southeastern sector of the archaeological site of Teotihuacan (Central Mexico) and the analytical protocol established for the complete characterization of these archaeological materials. For this purpose a multi-technique approach based on the combination of several non destructive and micro-destructive instrumental techniques, namely, light microscopy (LM), scanning electron microscopy-X-ray microanalysis (SEM-EDX), transmission electron microscopy (TEM), voltammetry of microparticles (VMP), X-ray microdiffraction (μXRD), X-ray diffraction (XRD), UV-Vis spectrophotometry, FTIR spectroscopy and gas chromatography-mass spectrometry (GC-MS) has been developed in an attempt to completely characterize these materials. These instrumental techniques provide reliable and complementary data including elemental and mineralogical composition, identification of functional groups as well as speciation studies of electroactive species. Among the most relevant findings, volcanic pyroclastic rocks and clayey soils, most probably, from the Teotihuacan valley as well as galena, jarosite and mica from other provenances in Mesoamerica, have been identified. Charcoal and Ocote resin have also been identified. The chemical composition of the samples is discussed with a view to the possible function as cosmetic materials and their use in funerary rites. The results have been critically compared with those others obtained in other ancient civilizations. The study carried out on the materials found in the burial 105 is especially relevant insofar it represents the first evidence, scientifically characterized, of the use of cosmetics in Mesoamerica at this early period (AD 200-550).     

Ushnus of the Inca provincial region: An analysis of two ceremonial platforms from Inca sites in Catamarca (Argentina)

The Inca polity deployed a variety of strategies in the establishment of imperial relations with the local communities of the southern provinces. These strategies included the translation of symbols materialized in architectural structures. In this sense, the ceremonial platforms denominated ushnus were spaces with particular significance and high hierarchy.     

Cajal's Views on the Nobel Prize for Physiology and Medicine (October 1904)

In this report we present and discuss an unpublished letter written by Santiago Ramón y Cajal in October 1904 in relation to his possible nomination for the Nobel Prize for Physiology and Medicine. This letter shows that Cajal was aware of his previous nominations for the Prize. He was convinced that these nominations had not been successful because neither anatomy nor histology were among the sciences included in the Nobel Statutes' definition of Physiology or Medicine. He gives a list of the merits he thought might be used for a new nomination, which included only works concluded during the previous five years.     

Spatial Inequality Between and Within Urban Areas: The Case of Israeli Cities

Central areas enjoy greater efficiency in the production of goods and services than do outlying areas. Because of the inherent advantages of central areas over outlying areas, disparities among regions do not vanish over time. On the contrary, centripetal forces increase inequalities across space. The phenomena of increased globalization, trade liberalization and treaties among countries not only enable the flow of labour, products (export) and foreign direct investment but also help reduce spatial inequality between countries. These phenomena also induce greater spatial economic concentration within a country. Thus, although disparities among countries decrease, a widening gap is observed between regions within countries and within large urban areas. In the empirical part, we analyse the general patterns of spatial inequality found among 55 localities in Israel with population size over 20,000. Looking at the spatial inequality relationship, both within and between cities in Israel, we show how all economic indicators measured, including inequality, decrease with distance from the core. Localities in the periphery that experience greater equality also experience lower average income, lower education, less self-employment and more unemployment.     

Calcium oxalate AMS C dating and chronology of post-Palaeolithic rock paintings in the Iberian Peninsula. Two dates from Abrigo de los Oculados (Henarejos,Cuenca, Spain)

Since 2005 we have been utilizing accelerator mass spectrometry (AMS) ¹⁴C dating in research on calcium oxalate crusts associated with open air rock art of the Iberian Peninsula. In this paper we present two dates linked with three eye-idol pictographs at Abrigo de los Oculados (Henarejos, Cuenca, Spain). Radiocarbon ages for these motifs agree with the expected iconography-based archaeological chronology. Such oxalate dates could provide an independent basis for evaluating chronological theories for post-Palaeolithic sites, designated in the UNESCO World Heritage List as Rock Art of the Mediterranean Basin on the Iberian Peninsula.     

The consequences of Wari contact in the Nasca region during the Middle Horizon: archaeological,skeletal, and isotopic evidence

During the Middle Horizon (AD 650–1000), the Wari polity expanded its sphere of control in various regions of the Andes, including Nasca on the south coast of Peru. The nature of the interaction between Wari and local communities varied. This study explores the consequences of Wari contact in the Nasca region at the site of La Tiza, which includes individuals dated to the Early Intermediate, Middle Horizon, and Late Intermediate periods. Using evidence for burial ritual along with demographic, paleopathological and isotopic data, population composition, mobility, diet, and health are investigated. δ¹³C data indicate a relatively stable diet through time at La Tiza with evidence for continued maize consumption, and paleopathological results indicate health problems associated with this type of diet. δ¹⁸O and ⁸⁷Sr/⁸⁶Sr data suggest that most of the individuals buried at La Tiza were local to the area. However, two female adults from the Middle Horizon burials are characterized as nonlocal based on δ¹⁸O and ⁸⁷Sr/⁸⁶Sr values and several individuals overlap with the ⁸⁷Sr/⁸⁶Sr local range for the Wari heartland. In conjunction with the use of new tomb types during this period these results highlight the ideological and populational changes occurring with Wari contact at La Tiza.
