Essai de détection de processus migratoires à travers les isotopes de strontium et d’oxygène : étude des restes humains du cimetière Saint-Matthew (Québec, 1771-1860)

Afin de distinguer les immigrants de première génération des individus nés à Québec et de discuter de l’identité des immigrants de cette ville aux XVIIIe et XIXe siècles, trente-quatre squelettes humains exhumés du cimetière protestant Saint-Matthew (Québec, 1771-1860) ont fait l’objet d’analyses ostéologiques et isotopiques du strontium (87Sr/86Sr) et de l’oxygène (δ18O). Les teneurs obtenues, bien que moins précises que les données historiques, ont permis de distinguer trois groupes d’origine, soit les individus nés à Québec (N = 12), les immigrants de première génération provenant le plus probablement des îles Britanniques et du nord de la France (N = 19) et les immigrants de première génération dont l’origine ne peut être précisée (N = 3). De plus, l’origine écossaise de certains individus a pu être suggérée en fonction de compositions isotopiques variant entre -10,0 et -9,09 % vs VSMOW. La comparaison des groupes d’origine à des données provenant de sources historiques et d’une étude antérieure a permis de dresser un portrait de l’identité des immigrants, à la fois sur les plans populationnel et individuel. De plus, les compositions isotopiques (δ18O, 87Sr/86Sr, δ13C et δ15N) nous laissent croire qu’au moins un individu pourrait être d’origine amérindienne et qu’un autre proviendrait d’une partie de l’Europe plus appauvrie en 18O (possiblement un pays scandinave ou une région alpine). La distribution spatiale des sépultures nous a également permis d’émettre des hypothèses sur les liens familiaux et sociaux d’immigrants inhumés en caveaux ou entassés de façon particulièrement modeste.

Évolution des pratiques alimentaires en cours de vie : une étude isotopique multi-matérielle de la population du cimetière Saint-Matthew (Québec, 1771-1860)

En tant que population majoritairement immigrante, les protestants inhumés au cimetière Saint-Matthew, ville de Québec (1771-1860) ont dû s'adapter à un nouvel environnement à leur arrivée au Québec, et donc à de nouvelles ressources. Parallèlement, les 18e et 19e siècles sont marqués par un contexte socio-économique en pleine mutation avec l'arrivée graduelle de la période industrielle, et la ville de Québec, avec son contexte portuaire, a ainsi été au coeur de ces changements. L'objectif de ce mémoire est d'évaluer si la géochimie des isotopes stables appliquée à plusieurs matériaux du squelette humain (collagène et apatite de l'os, collagène de la dentine, et carbonate de l'émail) permet de mieux comprendre comment les comportements alimentaires des individus analysés provenant de ce cimetière cosmopolite (n=40) ont évolué en cours de vie. L'alimentation étant influencée par des conditions socio-économiques, culturelles et environnementales, cela peut nous informer indirectement sur les processus d'adaptation et l'identité d'un individu. C'est dans cette perspective d'écologie culturelle que nous avons interprété les données recueillies lors de ce projet, en complément aux analyses effectuées précédemment par Morland (2009) et Caron (2013). Nos résultats corroborent les tendances déjà observées, soit des pratiques alimentaires semblables à celles que l'on retrouve en Europe, et des immigrants provenant majoritairement des Îles Britanniques. Ils démontrent également une légère augmentation de la consommation de ressources C4, comme le maïs et la canne à sucre, à l'âge adulte pour 90% des individus analysés, de même qu'une baisse du niveau de protéines. Par ailleurs, les individus étudiés ont généralement eu tendance à conserver le même niveau alimentaire les uns par rapport aux autres tout au cours de leur vie, même si les pratiques étaient moins diversifiés à l'âge adulte. Finalement, on constate des similarités de comportements avec les populations irlandaises et britanniques plus pauvres durant l'enfance, alors qu'ils ressemblent davantage à ceux visibles dans la vallée laurentienne en fin de vie, notamment en ce qui concerne l'apport en protéines. Nos résultats suggèrent donc des changements alimentaires significatifs, fort possiblement liés aux processus de migration et à une adaptation constante à un nouvel environnement de la part des individus étudiés.

La communauté du dehors : imaginaire social et représentations du crime au Québec (XIXe-XXe siècle)

La société québécoise a, comme toutes les sociétés, ses crimes et criminels légendaires. Or, si ces faits divers célèbres ont fait l’objet, dans les dernières décennies, de quelques reconstitutions historiographiques, on connaît beaucoup moins, en revanche, le mécanisme de leur légendarisation, le processus historique et culturel par lequel ils passent du « fait divers » au fait mémorable. C’est d’abord ce processus que s’attache à étudier cette thèse de doctorat, qui porte sur quatre crimes célèbres des XVIIIe et XIXe siècles (le meurtre du seigneur de Kamouraska [1839] ainsi que les crimes commis par « la Corriveau » [1763], par le « docteur l’Indienne » [1829] et par les « brigands du Cap-Rouge » [1834-1835]) : pour chacun de ces cas particuliers, l’analyse reconstitue la généalogie des représentations du crime et du criminel de manière à retracer la fabrication et l’évolution d’une mémoire collective. Celles-ci font chaque fois intervenir un système complexe de discours : au croisement entre les textes de presse, les récits issus de la tradition orale et les textes littéraires, l’imaginaire social fabrique, à partir de faits criminels ordinaires, de grandes figures antagoniques, incarnations du mal ou avatars du diable. Ce vaste processus d’antagonisation est en fait largement tributaire d’une époque (le XIXe siècle) où, dans les sociétés occidentales, le « crime » se trouve soudainement placé au cœur de toutes les préoccupations sociales et politiques : l’époque invente un véritable engouement littéraire pour le crime de même que tout un arsenal de savoirs spécialisés, d’idées nouvelles et de technologies destinées à connaître, mesurer et enrayer la criminalité. Dès les premières décennies du XIXe siècle, le phénomène se propage de ce côté-ci de l’Atlantique. Dans la foulée, les grands criminels qui marquent la mémoire collective sont appelés à devenir des ennemis imaginaires particulièrement rassembleurs : figures d’une altérité radicale, ils en viennent à constituer le repoussoir contre lequel, à partir du XIXe siècle, s’est en partie instituée la société québécoise.

The frequency and dynamics of stratospheric sudden warmings in the 21st century

Changes to stratospheric sudden warmings (SSWs) over the coming century, as predicted by the Geophysical Fluid Dynamics Laboratory (GFDL) chemistry climate model [Atmospheric Model With Transport and Chemistry (AMTRAC)], are investigated in detail. Two sets of integrations, each a three-member ensemble, are analyzed. The first set is driven with observed climate forcings between 1960 and 2004; the second is driven with climate forcings from a coupled model run, including trace gas concentrations representing a midrange estimate of future anthropogenic emissions between 1990 and 2099. A small positive trend in the frequency of SSWs is found. This trend, amounting to 1 event/decade over a century, is statistically significant at the 90% confidence level and is consistent over the two sets of model integrations. Comparison of the model SSW climatology between the late 20th and 21st centuries shows that the increase is largest toward the end of the winter season. In contrast, the dynamical properties are not significantly altered in the coming century, despite the increase in SSW frequency. Owing to the intrinsic complexity of our model, the direct cause of the predicted trend in SSW frequency remains an open question.

Roman diet and trade: evidence from organic residues on pottery sherds recovered at the Roman town of Calleva Atrebatum (Silchester Hants.)

The analysis of organic residues from pottery sherds using Gas-Chromatography with mass-spectroscopy (GC-MS) has revealed information about the variety of foods eaten and domestic routine at Silchester between the second and fourth–sixth centuries A.D. Two results are discussed in detail: those of a second-century Gauloise-type amphora and a fourth-century SE Dorset black-burnished ware (BB1) cooking pot, which reveal the use of pine pitch on the inner surface of the amphora and the use of animal fats (ruminant adipose fats) and leafy vegetables in cooking at the Roman town of Silchester, Hants.

Impact of increasing resolution and a warmer climate on extreme weather from NH extra-tropical cyclones

The effect of a warmer climate on the properties of extra-tropical cyclones is investigated using simulations of the ECHAM5 global climate model at resolutions of T213 (60 km) and T319 (40 km). Two periods representative of the end of the 20th and 21st centuries are investigated using the IPCC A1B scenario. The focus of the paper is on precipitation for the NH summer and winter seasons, however results from vorticity and winds are also presented. Similar number of events are identified at both resolutions. There are, however, a greater number of extreme precipitation events in the higher reso- lution run. The difference between maximum intensity distributions are shown to be statistically significant using a Kolmogorov-Smirnov test. A Generalised Pareto Distribution is used to analyse changes in extreme precipitation and wind events. In both resolutions, there is an increase in the number of ex- treme precipitation events in a warmer climate for all seasons, together with a reduction in return period. This is not associated with any increased verti- cal velocity, or with any increase in wind intensity in the winter and spring. However, there is an increase in wind extremes in the summer and autumn associated with tropical cyclones migrating into the extra-tropics.

European storminess and associated circulation weather types: future changes deduced from a multi-model ensemble of GCM simulations

A range of possible changes in the frequency and characteristics of European wind storms under future climate conditions was investigated on the basis of a multi-model ensemble of 9 coupled global climate model (GCM) simulations for the 20th and 21st centuries following the IPCC SRES A1B scenario. A multi-model approach allowed an estimation of the (un)certainties of the climate change signals. General changes in large-scale atmospheric flow were analysed, the occurrence of wind storms was quantified, and atmospheric features associated with wind storm events were considered. Identified storm days were investigated according to atmospheric circulation, associated pressure patterns, cyclone tracks and wind speed patterns. Validation against reanalysis data revealed that the GCMs are in general capable of realistically reproducing characteristics of European circulation weather types (CWTs) and wind storms. Results are given with respect to frequency of occurrence, storm-associated flow conditions, cyclone tracks and specific wind speed patterns. Under anthropogenic climate change conditions (SRES A1B scenario), increased frequency of westerly flow during winter is detected over the central European investigation area. In the ensemble mean, the number of detected wind storm days increases between 19 and 33% for 2 different measures of storminess, only 1 GCM revealed less storm days. The increased number of storm days detected in most models is disproportionately high compared to the related CWT changes. The mean intensity of cyclones associated with storm days in the ensemble mean increases by about 10 (±10)% in the Eastern Atlantic, near the British Isles and in the North Sea. Accordingly, wind speeds associated with storm events increase significantly by about 5 (±5)% over large parts of central Europe, mainly on days with westerly flow. The basic conclusions of this work remain valid if different ensemble contructions are considered, leaving out an outlier model or including multiple runs of one particular model.

Married woman and their landholdings: the evidence from feet of fines, 1310-1509

Despite the recent expansion in studies of medieval women, uncertainty surrounds their married lives due to the social and legal constraints that existed at that time. Here it is argued that feet of fines provide a lens, albeit partial, on the activities of married women who were effectively managing the disposal and inheritance of their landed estates. At the same time the importance to the purchaser of ensuring the lawful acquisition of the property is also observed. As a result, greater insights into married women and their property in the fourteenth and fifteenth centuries are obtained.

Strong armies, slow adaptation: civil-military relations and diffusion of military power

Why are some states more willing to adopt military innovations than others? Why, for example, were the great powers of Europe able to successfully reform their military practices to better adapt to and participate in the so-called military revolution of the sixteenth and seventeenth centuries while their most important extra-European competitor, the Ottoman Empire, failed to do so? This puzzle is best explained by two factors: civil-military relations and historical timing. In the Ottoman Empire, the emergence of an institutionally strong and internally cohesive army during the early stages of state formation—in the late fourteenth century—equipped the military with substantial bargaining powers. In contrast, the great powers of Europe drew heavily on private providers of military power during the military revolution and developed similar armies only by the second half of the seventeenth century, limiting the bargaining leverage of European militaries over their rulers. In essence, the Ottoman standing army was able to block reform efforts that it believed challenged its parochial interests. Absent a similar institutional challenge, European rulers initiated military reforms and motivated officers and military entrepreneurs to participate in the ongoing military revolution.

How Islamic is al-Qaeda? The politics of Pan-Islam and the challenge of modernisation

This article investigates the contested ideology of al-Qaeda through an analysis of Osama bin Ladin’s writings and public statements issued between 1994 and 2011, set in relation to the development of Islamic thought and changing socio-political realities in the late nineteenth and twentieth centuries. Challenging popular conceptions of Wahhabism and the “Salafi jihad”, it reveals an idealistic, Pan-Islamic sentiment at the core of his messages that is not based on the main schools of Islamic theology, but is the result of a crisis of meaning of Islam in the modern world. Both before and after the death of al-Qaeda’s iconic leader, the continuing process of religious, political and intellectual fragmentation of the Muslim world has led to bin Ladin’s vision for unity being replaced by local factions and individuals pursuing their own agendas in the name of al-Qaeda and Islam.

Survival at the frontier of Holy War: political expansion, crusading, commerce and the medieval colonizing settlement at Biała Gora, North Poland

Between the eleventh and thirteenth centuries AD, the Lower Vistula valley represented a permeable and shifting frontier between Pomerelia (eastern Pomerania), which had been incorporated into the Polish Christian state by the end of the tenth century, and the territories of western Prussian tribes, who had resisted attempts at Christianization. Pomeranian colonization eventually began to falter in the latter decades of the twelfth and early thirteenth centuries, most likely as a result of Prussian incursions, which saw the abandonment of sites across the borderland. Subsequently, the Teutonic Order and its allies led a protracted holy war against the Prussian tribes, which resulted in the conquest of the region and its incorporation into a theocratic state by the end of the thirteenth century. This was accompanied by a second wave of colonization, which resulted in the settlement pattern that is still visible in the landscape of north-central Poland today. However, not all colonies were destroyed or abandoned in between the two phases of colonization. The recently excavated site of Biała Góra, situated on the western side of the Forest of Sztum overlooking the River Nogat, represents a unique example of a transitional settlement that included both Pomeranian and Teutonic Order phases. The aim of this paper is to situate the site within its broader landscape context which can be characterized as a militarized frontier, where, from the later twelfth century and throughout much of the thirteenth century, political and economic expansion was combined with the ideology of Christian holy war and missionary activity. This paper considers how the colonists provisioned and sustained themselves in comparison to other sites within the region, and how Biała Góra may be tentatively linked to a documented but otherwise lost outpost in this volatile borderland.

The ecological impact of conquest and colonization on a medieval frontier landscape: combined palynological and geochemical analysis of lake sediments from Radzyń Chełminski, northern Poland

Slavic and German colonization of the southern Baltic between the 8th and 15th centuries A.D. is well-documented archaeologically and historically. Despite the large number of pollen profiles from Poland, few palaeoecological studies have examined the ecological impact of a process that was central to the expansion of European, Christian, societies. This study aims to redress this balance through multiproxy analysis of lake sediments from Radzyń Chełminski, Northern Poland, using pollen, element geochemistry (Inductively Coupled-Optical Emission Spectroscopy [ICP-OES]), organic content, and magnetic susceptibility. The close association between lake and medieval settlements presents the ideal opportunity to reconstruct past vegetation and land-use dynamics within a well-documented archaeological, historical, and cultural context. Three broad phases of increasing landscape impact are visible in the pollen and geochemical data dating from the 8th/9th, 10th/11th, and 13th centuries, reflecting successive phases of Slavic and German colonization. This involved the progressive clearance of oak-hornbeam dominated woodland and the development of an increasingly open agricultural landscape. Although the castles and towns of the Teutonic Order remain the most visible signs of medieval colonization, the palynological and geochemical data demonstrate that the major phase of woodland impact occurred during the preceding phase of Slavic expansion; Germans colonists were entering a landscape already significantly altered.

Papal power and protection in the Shebet Yehudah

The sixteenth-century Shebet Yehudah is an account of the persecutions of Jews in various countries and epochs, including their expulsion from Spain in the fifteenth century. It is not a medieval text and was written long after many of the events it describes. Yet although it cannot give us a contemporary medieval standpoint, it provides important insights into how later Jewish writers perceived Jewish–papal relations in the thirteenth, fourteenth, and fifteenth centuries. Although the extent to which Jewish communities came into contact either with the papacy as an institution or the actions of individual popes varied immensely, it is through analysis of Hebrew works such as the Shebet Yehudah that we are able to piece together a certain understanding of Jewish ideas about the medieval papacy as an institution and the policies of individual popes. This article argues that Jews knew only too well that papal protection was not unlimited, but always carefully circumscribed in accordance with Christian theology. It is hoped that it will be a scholarly contribution to our growing understanding of Jewish ideas about the papacy's spiritual and temporal power and authority in the Later Middle Ages and how this impacted on Jewish communities throughout medieval Europe.
