Spatial and temporal dynamics of the urban heat island effect in a small Brazilian city

This study examined the spatial and temporal patterns of the canopy layer urban heat islands (UHI_UCL) in a small city in southeastern Brazil using the local climate zone (LCZ) system. We analysed the influence of weather conditions, LCZs characteristics, and local surface relief on the UHI_UCL magnitudes. Mobile traverses were used to measure air temperatures during representative nights of wet and dry seasons. Daily maximum magnitudes were observed in compact classes (LCZs 3 and 7) under ideal weather conditions (dry, clear skies, and calm) and higher anthropogenic heat release (weekdays). Seasonal effects on LCZ thermal differences were negligible. The peripheral landscapes were warmer than the city centre in both seasons. Among the warmer areas in the city, magnitudes in compact LCZs 3 and 7 were consistently higher than in LCZ 6. In general, representative sites of the main ‘built’ LCZs in the study area exhibit similar inter-zone temperature patterns to those reported for cities of different sizes from tropical and midlatitude regions. Thermal contrasts of ΔT_{LCZ 3 − D} in the study area reveal significant evidence that small cities can have as strong heat islands as bigger cities. These findings highlight the importance of the LCZ system to identify the main controlling factors driving such thermal differences and the need to extend the application of this approach in other South American cities to yield systematic data of UHI_UCL for urban planning given the coming challenges of climate change over the region.     

Phaedrus’ Cicadas: Patrizi's Dialoghi and vernacular rhetoric

ABSTRACT

In his Dieci dialoghi della retorica (Venice, 1562), Francesco Patrizi analyses the nature of language and the historical developments of oratory, taking part in the debate on this art reinforced by the spread of the Aristotelian Rhetoric. This gave him the opportunity to consider the origins of human social life and explain the traditional rhetorical teaching in an anthropological perspective. He also argued against the civic use of oratory as presented in some contemporary treatises on it, written in the vernacular.     

Colonial Servicemen and their British ‘War Brides’: First World War Marriages in the British Empire

This article uses the phenomenon and failure of war marriages between British women and ‘colonial’ servicemen, mostly from the settler dominions, to explore the gendered, classed and racialised conditions of migration after the First World War. Positioning this migration of British war brides as part of the continued normalisation of settler occupation, the article demonstrates the patriarchal social expectations to which white women were subject. Fears of ‘khaki fever’ were extended to the protection of naïve ‘colonial’ soldiers from the manipulative sexuality of white, particularly working-class, women and girls. At the same time, ‘respectable’ women were prepared for frontier life and protected from the indignities of bigamy and desertion. The emphasis on their role as ‘daughters of Empire’ meant ‘undesirable’ matches and marital failure, as reported by the press, had consequences for the closeness of the imperial family and the maintenance of white superiority. The mediation of mobility in cases of mixed-race marriage indicate a more explicit, and sometimes violent, policing of the sexual independence of women and Black and indigenous men of colour. In doing so, the article makes an important contribution to understandings of the legacies of global mobilisation and colonial encounters during the First World War.     

Possible cases of leprosy and tuberculosis in medieval Sigtuna,Sweden

In Sigtuna, Sweden, a medieval cemetery, including 227 skeletons, was analysed in 2006. On the outskirts of the churchyard, six skeletons with bone changes indicating systemic inflammatory disease were observed. Two out of three individuals with well‐preserved facial bone regions displayed signs of rhinomaxillary remodelling. Four of the afflicted exhibit severe bilateral alterations of the lower legs and phalanges of the feet and concentric atrophy of the metatarsals. In addition, one of the individuals exhibited a kyphosis in the lumbar vertebrae. In a discussion about alternative diagnoses, lepromatous leprosy and tuberculosis were identified as the causes of the destructive lesions in two individuals. Though the skeletal changes of the lower legs and feet in four cases demonstrate a close resemblance to secondary lesions of leprosy, the disease could not be confirmed. The skeletal changes of the last individual were unspecific and the possible causes several, rendering diagnosis difficult. The burial locations imply that the afflicted persons belonged to a lower social stratum. Due to the significantly higher frequency of pathological changes in the cemetery compared to other cemeteries in the town, the individuals could be regarded as fellow sufferers among others with various medical conditions. The bioarchaeological identification of systemic infectious diseases of a group of individuals of this size is unique to north of Scania in Sweden, where only a few cases of leprosy and tuberculosis have previously been diagnosed. The significance of the present study is emphasised by the interconnection between the afflicted, the archaeological context and the knowledge of the medieval society in Sigtuna.
