Fluctuations in land values in a rural municipality in southern Québec, Canada

The agro-forested region of the Haut-St-Laurent, in southwestern Québec, in Canada, has served as a laboratory for several years to a multi-disciplinary research team seeking to understand the interplay of stakeholders and processes influencing the rural space of southern Québec. Following directly in the footsteps of previous research, this study was undertaken to analyze the hitherto neglected but important aspect of fluctuations in land values with respect to geomorphology and land use, during the 1958–1997 period. A geo-referenced database was built within an object-oriented geographic information system (GIS) that includes data from the sale of parcels of land within the study area, land registry maps, land use maps, and a geomorphological map. These data were analyzed and sorted through queries addressed to the database. Finally, a statistical analysis was performed to analyze the relationship between sale price, geomorphology and indirectly land use, for the entire study period and for each of its decades. The results show that land value has increased at different times during the past, according to its geomorphological type and land use. These relationships are explained by the important transformation phases that have affected southern Québec during the second half of the twentieth century.     

HANNIBAL'S INVASION ROUTE: AN AGE‐OLD QUESTION REVISITED WITHIN A GEOARCHAEOLOGICAL AND PALAEOBOTANICAL CONTEXT

The point of Hannibal's departure from New Carthage in Iberia, in 218 bc , and his subsequent march along the Mediterranean coast to the Pyrénées and on to the Rhône Basin, has been reconstructed by ancient historians with considerable accuracy. The latter 400‐km phase through the Alps, however, has been the subject of some controversy as to whether the Punic Army followed a southern versus a northern invasion route, or some intermediate variant. What is certain from the ancient texts is that Hannibal was trapped by Gallic tribes in a large defile—a gorge large enough to hold the entire army—along the approach to the high col of passage on to the Po River Plains of northern Italia. The entrapment involved an enfilade attack planned by an unknown Gallic commander, a military operation that nearly decimated the Punic Army. Previous arguments as to the location of the defile have hinged on inconclusive topographic, geological and geomorphic assessments. New data from palaeobotanical reconstruction of the northern approach route show the Gorges de la Bourne and the Gorge du Bréda, astride the Isère River, to have been forest covered during the invasion, which would have made the Gallic assault impossible. The existing evidence argues for a southern route, the approach through the narrow defile of the Combe de Queyras, with passage over the Col de la Traversette, as argued by Sir Gavin de Beer nearly a half century ago. Narrowing the approach route focuses on sites worth geoarchaeological exploration.     

CHARACTERIZATION OF PLASTERS FROM PTOLEMAIC BATHS: NEW EXCAVATIONS NEAR THE KARNAK TEMPLE COMPLEX,UPPER EGYPT*

The aim of the present work is to characterize plasters from Ptolemaic baths recently discovered in front of the Karnak temple complex, by the excavations of an Egyptian–French team. The characterization was carried out by means of optical microscopy (OM), scanning electron microscopy (SEM) equipped with an energy‐dispersive X‐ray detector (EDS), X‐ray diffraction analysis (XRD) and Fourier transform infrared spectroscopy (FT–IR). The results allowed the identification of the chemical composition and structure of these plasters. In addition, samples of red, yellow, black and white pigments were examined and identified. The results helped in providing an image concerning some materials used during the Ptolemaic era in ancient Egypt.     

A CRITICAL REVIEW OF THE SEISMIC HAZARD ZONING OF PESHAWAR AND ADJOINING AREAS

Many of the structural engineers in Pakistan refer to the UBC code for the design of aseismic structures. On the seismic zones of international cities, the UBC code 1997 has placed Peshawar in the most severe earthquake Zone 4 similar to the high earthquake prone cities of California, Alaska, Japan, Chile, Taiwan or Turkey. These places have suffered some of the most destructive earthquakes of the past. The earthquake history of Peshawar, however, does not inform us about moderate devastation. Moreover work done on the seismic zoning of Pakistan by different national and international agencies and independent researchers present widely conflicting pictures of the seismic hazard of Peshawar. This paper critically reviews almost all of the published work done on seismic zoning, in the light of the locally available data, geology, tectonics and earthquake history of Peshawar.     

SOUTHERN ASIA'S OLDEST INCENDIARY MISSILE?*

A small burnt ball was recovered in 1995 from the basal fills of a ditch surrounding the Bala Hisar, or High Fort, of Charsadda, Pakistan. Associated by Sir Mortimer Wheeler with the siege of the ancient site by Alexander the Great in 327 bce , the ditch forms part of the city's defensive circuit. Using geochemical and microscopic techniques (X‐ray diffraction, micro‐FTIR, SEM and GC–MS) the ball is identified as an artificial composite of mineral (mostly barite) and flammable resinous organic matter originating from conifers from the Podocarpaceae, Araucariaceae and Cupressaceae. The physical and chemical nature of the find suggests that the ball was ignited in a fire, although whether this was a deliberate or accidental occurrence is impossible to establish. The analytical data, combined with the archaeological context of the find, leads us to evaluate whether the find represents southern Asia's earliest incendiary missile.     

THE IMPACT OF SOLUBLE SALTS ON THE DETERIORATION OF PHARAONIC AND COPTIC WALL PAINTINGS AT AL QURNA,EGYPT: MINERALOGY AND CHEMISTRY*

The wall paintings of Al Qurna in Egypt were studied by means of XRD and ICP–AES in order to determine their mineralogical and chemical composition, and to evaluate the impact of soluble salts on their deterioration, including the identification of the building materials and pigments used. Soluble salts analysis showed that NaCl is the most common soluble salt in the bedrock, ground water and surface water samples. The building materials are affected by the ground water, while the wall paintings in the area are affected by the Upper Egypt climatic conditions, which were studied in order to detect their role in the deterioration cycle in the area.

Iran under Ahmadinejad: populism and its malcontents

This article assesses the rise of President Ahmadinejad from the perspective of the Weberian concept of charismatic authority. It argues that in re‐engaging with an authoritative structure founded on charisma, the hard line political establishment of the Islamic Republic have returned to a traditional form of autocratic power which is inherently unstable. The cycle of distress and enthusiasm from which it grows generates a momentum and ideological polarization which the leaders of the Islamic Republic may find increasingly difficult to escape.
