The use of tree-rings and foliage as an archive of volcanogenic cation deposition.

2007

Tree cores (Pinus nigra ssp. laricio) and leaves (Castanea sativa) from the flanks of Mount Etna, Sicily were analysed by ICP-MS to investigate whether volcanogenic cations within plant material provide an archive of a volcano's temporal and spatial depositional influence. There is significant compositional variability both within and between trees, but no systematic dendrochemical correlation with periods of effusive, explosive or increased degassing activity. Dendrochemistry does not provide a record of persistent but fluctuating volcanic activity. Foliar levels of bioaccumulated cations correspond to modelled plume transport patterns, and map short-term volcanic fumigation. Around the fl…

Kant and the scientific study of consciousness.

2010

We argue that Kant’s views about consciousness, the mind—body problem and the status of psychology as a science all differ drastically from the way in which these topics are conjoined in present debates about the prominent idea of a science of consciousness. Kant never used the concept of consciousness in the now dominant sense of phenomenal qualia; his discussions of the mind—body problem center not on the reducibility of mental properties but of substances; and his views about the possibility of psychology as a science did not employ the requirement of a mechanistic explanation, but of a quantification of phenomena. This shows strikingly how deeply philosophical problems and conceptions c…

“A Perfect Heroine in Foreign Travel.” Female Mobile Identities and Southern Italy in the 19th Century Non-feminist Periodical Press

2016

This essay focuses on the inteaction between the publication of female travel writing abouth the South Of Italy in non -feminist 19th century British periodicaldìs and the circulation of a transgressive model of femininity centred on the concepts of mobility, vitality and visibility. the choice of Southern Italy, and anti-tourist destination that since the era of the Grand Tour had been considered dangerous for men, let alone for women, magnifies female heroic attitudes and contaminates female conventional domestic purity enhancing the concept of an unfixed female identity. The publications of a travelogue, a mostly non fictional genre, on an innovative and reactive medium, was a manifest a…

Mundo obrero, cultura y asociacionismo: algunas reflexiones sobre modelos y pervivencias formales

2003

In this article, the author reflects on the associative models chosen by Spanish working and popular classes since the middle of nineteenth century in order to defend their interests, especially in the case of the difussion of culture and education. It is remarkable the continuity and success of some inherited prototypes, as it happened with the «ateneos» until the years of the Spanish civil war. At the same time, workers' organizations tried to satisfy an extensive range of demands by developing multifunctional centres. Examples of these were the «Casas del Pueblo» (People's Houses) erected by the socialist movement.

Bourgeois Women and the Question of Divorce in Finland in the Late 19th and Early 20th Centuries

2017

This article explores perceptions and actions of Finnish upper-middle-class women with regard to divorce in the late 19th century and early 20th century. Divorce was discussed in the periodicals of bourgeois women’s associations and later in Finnish Parliament, in which several leading figures of the bourgeois women’s associations were elected as members from 1907 onwards. Compared to other issues related to marriage and its legislation, divorce was not an especially important question for bourgeois women, but a tool to promote other issues. Women writers demanded drunkenness and violence as new grounds for divorce, and proposed that loveless marriages should be made possible to dissolve. M…

A new multi analytical approach for the identification of synthetic and natural dyes mixtures. The case of orcein-mauveine mixture in a historical dr…

2017

In this paper, the application of a multi-analytical approach for the characterisation of synthetic and natural dyes in a historical textile is presented. The work is focused on a historical dress of a Sicilian noblewoman, dating from about 1865–1870. Firstly, SERS on fibre was performed, in order to individuate the classes of dyes employed. The SERS spectra suggested the presence of two main dyes: mauveine and orcein. In order to confirm these preliminary results, two different extraction protocols were applied. The extracts obtained were analysed by ESI-MS, MALDI-ToF and UHPCL-MS analyses, confirming the SERS results. In particular, the application of the ammonia mild extraction technique…

History of bioavailable lead and iron in the Greater North Sea and Iceland during the last millennium – A bivalve sclerochronological reconstruction

2014

We present the first annually resolved record of biologically available Pb and Fe in the Greater North Sea and Iceland during 1040-2004 AD based on shells of the long-lived marine bivalve Arctica islandica. The iron content in pre-industrial shells from the North Sea largely remained below the detection limit. Only since 1830, shell Fe levels rose gradually reflecting the combined effect of increased terrestrial runoff of iron-bearing sediments and eutrophication. Although the lead gasoline peak of the 20th century was well recorded by the shells, bivalves that lived during the medieval heyday of metallurgy showed four-fold higher shell Pb levels than modern specimens. Presumably, pre-indus…

The Jewish doctors involved in the development of health resorts in eastern Galicia at the late 19th and early 20th century (Central and Eastern Euro…

2018

Summary Background The involvement of Jewish doctors and scientists in the development of health resorts in eastern Galicia (part of the Austrian monarchy after 1772, and since 1918 as part of independent Poland, now part of Ukraine) is unquestionable; however, awareness of this fact is not that common. Meanwhile, also due to their work and activity, small borderland resorts became important medical, cultural and social centers of the region. The involvement of Jewish doctors in the development of Galician health resorts resulted from, among others, the rich and multi-layered tradition and integration of Judaism with the hygiene regulations and moral principles of the religion. The eastern …

Louis Jacques Thenard's Chemistry Courses at the Collège de France, 1804–1835

2010

This article is concerned with the public courses and lecture demonstrations given by Louis Jacques Thenard at the College de France during the first decades of the nineteenth century. The expectations and needs of Thenard's auditors will be studied in order to understand the role played by chemistry courses at the College in the context of the growing and changing Parisian teaching market during the first third of the nineteenth century. The preparation and performance of lecture demonstrations was the main driving force of several major changes in the premises and the personnel associated with the chair of chemistry. Our analysis of the parallel process of expansion and functional differe…
