COVID-19 in Chihuahua,Mexico: Assessing its spatial behaviour through the inverse distance weighted interpolation technique

This study focused on the spatial evolution of COVID-19 in the state of Chihuahua, Mexico. Data were retrieved from governmental databases and analyzed by means of GIS, applying the inverse distance weighted (IDW) method. The period of December 2019 through November 2021 was split into eight seasons. The root mean square error (RMSE) was used to assess the reliability of the interpolations, showing acceptable values (RSME < 25). During the period, the municipalities of Juarez and Chihuahua reached the highest number of confirmed cases and deaths, Juarez being the main hotspot of contagion (37.2% of confirmed cases; 46.9% of deaths). Four waves of contagion were identified during the evaluated period, with Fall 2020 being the strongest season. Since Fall 2020, the spread of the disease was more often observed in municipalities with the highest human mobility. Although the spread of COVID-19 decreased after Spring 2021, in Fall 2021 records indicated a continuous increase in cases in the state. That could be due to a relaxation of the implementation of sanitary measures, as well as to the propagation of novel COVID-19 variants having an elevated infectious level. Geospatial techniques allowed for an understanding of the spatial spread of COVID-19 and could be useful for its control.     

The 18th-Century Baraccato of L’Aquila

ABSTRACT

This article attempts to describe a particular form of baraccata house, found in L’Aquila, Italy. The differences between this form of baraccato and the Italian traditional timber-framed (T-F) structures, the baraccato borbonico and the baraccato alla beneventana, are shown. In the upper valley of the Aterno river (Abruzzo, Italy), a few kilometers far from L’Aquila, wonderful 18^th-century examples of T-F masonry structures are present. The use of wood pervades both the poor and noble buildings. In this article, the documentary and functional features of this peculiar anti-seismic timber-based building technique, which is widespread in L’Aquila and the neighboring areas, is described. After a comparative analysis of the technique’s features, the case of three T-F buildings, belonging to three different social classes is reported, the first is the Ricci palace in Mopolino di Montereale, the second is a middle-class building, and the third is a rural one. The 1703 earthquake, which affected the upper valley of the Aterno river and the nearby city of L’Aquila, gave rise to an ante litteram anti-seismic culture. Timber was not seen as an obstacle to durability but a material to be exploited to protect buildings from earthquakes.     

A Multidisciplinary Study on the Seismic Vulnerability of St. Agostino Church in Amatrice following the 2016 Seismic Sequence

ABSTRACT

The big earthquake of August 24, 2016 and subsequent major shocks severely damaged many historic villages in Central Italy and dramatically showed the intrinsic vulnerability of the diffused architectural heritage. The St. Agostino church is one of the collapsed historical buildings, being inside the epicentre village of Amatrice. During the long seismic earthquake swarm, progressively the church was damaged and monitored. This multidisciplinary study of the damage of the church includes correlations of all the data derived from three steps geomatics surveys (3D aerial and terrestrial models): the archival drawings and images documenting previous events distressing the building, the previous strengthening intervention, and finally the seismic site response analysis (from Amatrice’s accelerometric station). Through a back analysis carried out by a finite elements model, it was possible to understand the seismic vulnerability of this historical building, in relation to the previous interventions and damage events. The proposed methodology, based on the interdisciplinary data analysis, provides useful information for the next strengthening projects of damaged historical monument.     

First record of the ichthyodectiform fish Xiphactinus (Teleostei) from Patagonia,Argentina

Abstract

We report the first record of the genus Xiphactinus from southern South America. The recovered fossil material consists of an associated maxilla and abdominal vertebra, probably derived from latest Maastrichtian marine deposits of the Salamanca Formation in Chubut Province, Argentina. Xiphactinus has been widely reported from Late Cretaceous strata throughout the Northern Hemisphere, although to date, equivalent Southern Hemisphere occurrences include only a single specimen from Venezuela. Our new discovery thus indicates that Xiphactinus had a much more cosmopolitan distribution, encompassing the southern paleolatitudinal extremities of South America during the terminal Cretaceous.

Russia,China, and the universalism of modernity: the “Account of the Reforms of Peter the Great” by Kang Youwei

ABSTRACT

This paper analyzes a short essay by Kang Youwei (1858–1927) – one of the intellectual and political protagonists of late imperial and early Republican China. In it, he interpreted the historical experience of Russian modernization under Peter the Great (1672–1725) and used it as a “success story” for the renewal of Chinese monarchical institutions. It was written in 1898 and presented to the Manchu throne under the title “Account of the Reforms of Peter the Great”, and for our purposes will be the departing point for a “global intellectual circuit” through which the following questions will be addressed: Why was seventeenth and eighteenth century Russia considered as a model for China by the author? How did he manage to adapt the historical experience of Russia into a social and political conceptual framework for China? What was Kang’s historiographical method, and what kind of philosophy of history framed his reflections? What does this short essay tell us about Kang’s view on “Westernization”, on the concept of “modernity” itself, and on its use for historiographical purposes?     

The interplay between school and home location and its relationship with children’s subjective well-being

ABSTRACT

The aim is to determine the extent to which children’s subjective well-being (SWB) varies according to age, gender and the fact of living in the same context as the school (urban/rural) or not, in representative samples of 8, 10 and 12-year-olds (N?=?3708) in Spain. The existence of a match between schoolchildren’s living context and that of their school was the most common situation for the participants. The results, analysed using linear regression models and analysis of variance (ANOVA) with complex samples, show that a match between home and school context is not associated with statistically different levels of SWB in the three age groups (8, 10 and 12-year-olds) or by gender. Whereas no interactions between age, gender, school context and home location contribute to explaining overall life satisfaction, some do contribute to explaining the modified version of the Student’s Life Satisfaction Scale (SLSS) used here.     

The landscape of Metztitlan,Mexico: Power and control in a sixteenth century Spanish administrative painting

ABSTRACT

The concept of landscape has been studied mostly as the view of a space with particular interest in its aesthetics, originating at the turn of the sixteenth century. However, I argue that in fourteenth century northern Europe, the concept was focused on polity rather than aesthetics. This article examines this lesser-known tradition by analysing the painting of Metztitlan, a sixteenth century town in Mexico, and arguing, first, that unlike all the other representations in the Relaciones Geográficas to which it belongs, it is the only landscape, and second, that this painting is associated with an administrative procedure common in Spain to gain control over imperial lands. I review European practices regarding the representation of towns under the Spanish Crown. Then, I present the results of the fieldwork carried out to locate several heights which probably served as vantage points to paint the landscape. Based on this research, I analyse the intentions of the painter to argue that it should be considered within the same tradition as the paintings made in Spain by Flemish painter Anton van de Wyngaerde, as part of the Spanish Empire's Germanic tradition of describing places with the intention of exerting control over them.
