Canada: How Many Glaciations?

Editor's note: The first President's Symposium was held during the cag annual meeting at the University of Winnipeg in 1983. The idea was to air some broad and invigorating topic to which invited specialists from across the country could contribute under presidential direction. The inaugural topic selected by the president, Professor D.C. Ford, was ‘Canada: how many glaciations?’ The specialist contributors certainly learned a great deal, and the symposium was well received by the general membership whom the specialists wished to interest. This article consists of a summary of the presentations made by the various contributors and a concluding polemic.     

Production and use of birch bark tar at the Neolithic pile-dwelling of Palù di Livenza (North-Eastern Italy) revealed by X-ray computed micro-tomography and synchrotron Fourier-transform infrared spectroscopy

Recent excavations at Palù di Livenza (northeastern Italy) revealed a multiphase Neolithic pile dwelling dated between ca. 4,300/4200 and 3,600 cal BC. Three lumps with teeth imprints and a larger amorphous piece from the Late Neolithic layers have been studied by X-ray computed micro-tomography (microCT) and synchrotron Fourier-transform infrared spectroscopy (FTIR). FTIR spectra match well that of birch bark tar and microCT of the larger piece has revealed a rolled-up structure likely corresponding to bark rolls. The lumps of birch pitch were probably chewed to soften the tar prior to be used as hafting adhesive or therapeutic substance. The rolled-up inner structure of the larger piece and the remains of birch bark tar and abundant charcoals on its surface suggest it probably corresponds to a rare waste product from allothermic tar production.     

Rosa e Ballo and German literature in Italy: the genesis of an intellectual network and the production of a new repertoire in the field of theatre

Between 1944 and 1950 the publishing house Rosa e Ballo renewed the Italian repertoire of German dramatic literature by collecting translations from Büchner, Wedekind, Toller, Kaiser and Brecht in the book series ‘Teatro/Teatro moderno’. The series was designed by Paolo Grassi, who was then struggling to legitimize the teatro di regia (director’s theatre) against the dominant teatro del grande attore (lead actor’s theatre), a revolution he would accomplish after WWII by establishing the Piccolo teatro in Milan. The company and the network of collaborators set up in Turin and Milan by the editor-in-chief Ferdinando Ballo provided Grassi with an ideal instrument for his subversion in the field of theatre. In turn, Grassi’s networking in Rome, where the most recognized men of theatre were based, brought to Rosa e Ballo its most successful book series and finally a position within the field of publishing. By joining forces, newcomers in two different fields mutually contributed to their primary accumulation of symbolic capital.     

Sins of memory: reflections on the lack of an Italian Nuremberg and the administration of international justice after 1945

This article reconstructs the history of the major trial that the Allies planned to institute against the entire military command of the Nazi armies operating in Italy from 1943 to 1945. The trial was prepared on the same juridical and technical bases as the Nuremberg Tribunal, but it never took place. The reason was that it would have jeopardized the re-integration of the Federal Republic in the European community, and would also have risked placing the Italian government in the embarrassing position of having the Italian army prosecuted for crimes committed in the countries occupied by the Rome?–?Berlin axis. For those reasons, the trial was abandoned and instead only legal proceedings were taken only for some marginal cases, creating the impression that these were simply isolated cases of individual responsibility. The enigma of this missing trial and an explanation of the limits of international justice can only be understood in terms of the political situation in post-war Europe, the relations between Italy and the Allies and the double game played by the Italian government. These events served, however, to give rise to highly selective memories of totalitarianism and the war.     

The Roman quarries at Antinoopolis (Egypt): development and techniques

The aim of this research was the survey and the study of the many quarries located in the first spurs of the Gebel el-’Adila, close to Antinoopolis (Middle Egypt). These quarries are an excellent opportunity for observation and research concerning the “landscape archives” and preserve traces of man’s activity, representing a real cultural heritage. The paper gives a short geological setting of the area and reports our recent study (2006 onward) on traces, typologies, methods and development of the quarrying activity in the area, focussing on the Roman period. The working traces allowed us to define the working tools used for quarrying, the organisation of the works and of the quarry exploitation, as in the area many remains of the quarry organisation network are extant or recognisable, such as: service posts, sledge-ways, docks.     

Worker Housing in the Vermont Copper Belt: Improving Life and Industry Through Paternalism and Resistance

During the mid-nineteenth century, east-central Vermont supported two major copper mines and their associated villages. In order to wrest thousands of tons of copper from the earth these mines, the Elizabeth and Ely mines, hired and housed thousands of miners, laborers, and their families. Both mines pursued the same resource in the same environment during the same period, but the Ely Mine developed a centralized village, while the Elizabeth Mine housed its workers in isolated housing clusters. The causes of these differences in worker housing can be traced to differences in scale, setting, and managerial philosophy, and can be analyzed within the larger historical context of Improvement and the larger ethnographic context of paternalism in mining communities.     

Adhesion An Interdisciplinary Science

Abstract

The interdisciplinary science of adhesion is built upon contributions from the classical branches of science: chemistry, physics and mathematics, and some of their more specialized subdivisions such as polymer chemistry, surface chemistry, rheology and continuum mechanics. An historical review of the development of adhesive technology stresses the role of polymer chemistry in the advances made in modern adhesion technology, but many other disciplines have contributed. Their roles are discussed from the point of view of adhesion theories that are biased toward one discipline or another. Such bias can lead to fallacy. Challenging adhesion problems still exist and their solution will involve other disciplines, like biology and medicine.
