SummaryBorn to a noble family in the Italian Trentino, Prati studied philosophy in Austria and Germany. Returning to Italy, he joined the carbonari, a network of revolutionary secret societies. Forced into exile in Switzerland, he worked as an educator alongside Pestalozzi. Following his expulsion from Switzerland, Prati sought refuge in Britain, becoming acquainted with Coleridge, the Benthamite utilitarians, and the Owenites. Following the July Revolution, Prati went to Paris, where he became a Saint-Simonian. Returning to Britain, he sought to convert the British to Saint-Simonism, before undertaking a series of other literary projects. He eventually returned to Italy, where he entered into correspondence with the Roman Catholic philosopher Antonio Rosmini. Prati left behind him a trail of letters, newspaper articles, pamphlets, and books, written in four different European languages. These have been hitherto neglected by scholars, and constitute the basis of the current article. 相似文献

Hydraulic plasters or mortars prior to the Roman period are rare. Here, we report the identification and characterization of 3000 year old (Iron Age) hydraulic plaster surfaces from the site of Tell es-Safi/Gath. This site, located in central Israel, was occupied almost continuously from prehistoric through modern times, and is identified as the Canaanite and Philistine city of Gath. A survey using an on-site Fourier transform infrared spectrometer (FTIR) identified the presence of amorphous silicates, in addition to calcite, in each of two superimposed plaster layers. This suite of minerals is characteristic of hydraulic plaster. An in-depth characterization of the plasters using FTIR, acid dissolution, X-ray fluorescence (XRF), X-ray powder diffractometry (pXRD), heating experiments and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (SEM–EDS), shows that special silicate-containing minerals were brought from some distance to the site in order to produce these plaster surfaces. We therefore conclude that the plasters were deliberately produced, and were not the result of a fortuitous addition of local silicate minerals. A layer of around 150 μm thick enriched in carbonate hydroxylapatite was found in both plaster surfaces, and the same mineral was identified by infrared spectrometry in the surrounding sediments. This suggests that organic materials were used on these surfaces. These surfaces are among the oldest hydraulic plasters known. 相似文献

This article deals with actual and potential contributions of history to policy studies. Some historians have attempted to influence specific policies through their writings, others have held policy-relevant positions in government agencies, while others have functioned in roles that have made them official preservers of our past. The authors discuss a number of ways in which history is relevant to policy studies-among them, the conception of history as a policy laboratory, as a source for perspective about the development of current policies, as a source of theoretically interesting rare or unique occurrences, and as a repository of values to which appeals can be made to justify current and proposed policies. Historians are becoming aware of the need for alternative careers to teaching in universities and this has led them to seek an increase in the number of policy-relevant positions for historians in government. 相似文献
