REGIONAL TRAJECTORIES OF TECHNOLOGICAL CHANGE IN CANADIAN MANUFACTURING

Techniques of production were measured for 18 manufacturing industries across 6 regions of Canada between 1961 and 1988. In any given year, production technology, measured by a pair of capital and labour input coefficients, varies markedly over space. The relative positions of regions in a two-dimensional technology-space appears consistent across industries. With industry-mix effects removed, multivariate analysis of variance confirms that regional differences in production techniques are significant. Further investigation reveals that spatial variations in techniques of production persist over time. These findings support the claims of evolutionary theorists, demonstrating that in Canadian manufacturing industries regions tend to move along distinct trajectories of technological change.
On a mesuré les techniques de production dans 18 industries manufacturières de 6 régions du Canada au cours de la période 1961-88. La technologie de production, mesurée par deux coefficients des entrées du capital et du travail, diffère considérablement d'une région à l'autre à une année donnée. Les positions relatives des régions par rapport aux deux dimensions espace-technologie se maintiennent dans toutes les industries. Si on écarte les effets de la composition industrielle, l'analyse de variance à plusieurs variables démontre qu'il existe d'importantes différences régionales en techniques de production. L'analyse complémentaire révèle que les variations spatiales des techniques de production persistent à travers le temps. Ces résultats confirment la position des théoriciens évolutionnistes à l'effet que dans les industries manufacturières canadiennes, les régions ont tendance à suivre des trajectoires distinctes de changements technologiques.     

RECENT ENVIRONMENTAL CHANGE IN THE SOUTHWESTERN CANADIAN PLAINS

This paper examines 20th-century environmental change in the subhumid southwestern Canadian Plains, specifically in relation to the dominant agricultural landscape and to the climate of the past millennium as reconstructed from proxy data. Anthropogenic landscape change in the last century has been dominated by the conversion of grasslands to ranchland and cropland. This has heightened landscape vulnerability to climatic fluctuations, especially drought. Instrumental climate records, extending back to the 1880s, highlight the variability of precipitation in this region. Proxy environmental records, derived from lake cores and tree-ring analysis, extend this picture into the last millennium and show that drought has been a recurring theme of the Prairie climate. Tree-ring records suggest that some droughts in the last millennium may have exceeded in severity any in the instrumental record. The sustainability of Prairie agriculture depends on adaptation to the amplitudes of climatic change and variability evident in these proxy records. Dans cet article nous examinons les changements environnementaux qui sont survenus pendant le 20^ème siècle dans les plaines canadiennes sèches du sud-ouest, spécifiquement par rapport au paysage agricole dominant et au climat du dernier millénaire qui a été déterminéà partir de données de procuration. La transformation des prairies en ranchland et cropland est le changement du paysage le plus important dont l'homme est responsable, pour le dernier siècle. À cause de ce changement, le paysage est plus vulnérable aux fluctuations climatiques - à la sécheresse en particulier. Les enregistrements instrumentaux de climat, qui reculent jusqu'aux années 1880, mettent en évidence la variabilité des précipitations dans cette région. Les enregistrements environnementaux de procuration, dérivés d'échantillons pris dans les lacs et de la dendroanalyse, étendent cette image dans le dernier millénaire et prouvent que le thème de la sécheresse est apparu souvent dans les analyses du climat du prairie. Les enregistrements de boucles d'arbre suggèrent que, dans le dernier millénaire il y avait des sécheresses qui étaient peut-être si sévères que les instruments n'ont pas pu les enregistrer. Si l'agriculture veut survivre comme entreprise dans les prairies, il faudra qu'elle s'adapte aux amplitudes de changement et de variabilité du climat qui ont été constatées dans les données de procuration.     

Spatial Variations,Contextual and Social Structural Influences on Voting for the ALP at the 1996 Federal Election: Conclusions from Multilevel Analyses

Multilevel modelling of individual survey data from the 1996 Australian Election Study and aggregate contextual Census data is used to investigate the extent of spatial variations in voting at the 1996 election, and to examine potential explanations for the variations. The size of the variations was about the same as at the 1993 election, and was again mainly at the divisional rather than the state level. However, unlike in 1993, only a small amount of the variations could be explained by differences in the individual sociodemographic compositions of the areas, suggesting that local influences were more important in 1996 than 1993. The most significant change in the effect of the individual-level variables between the two elections was that the influence of being personally unemployed completely changed direction (working against the ALP in 1996, whereas it had favoured it in 1993), although the estimated strengths of several others also changed. I suggest that the concentration of the 1993 election on the 'Fightback' package might be the main cause of many of these differences. The nature of the main contextual influences is similar to those at the 1993 election, involving an urban-rural effect, a local economic effect and an ethnic effect, confirming that these are more than short-term factors. However, there also remain somewhat larger unexplained local influences than in 1993. Detailed investigation of the ethnic contextual effect suggests the presence of a specifically anti-Asian influence.     

Maps Narratives and Trails: Performativity,Hodology and Distributed Knowledges in Complex Adaptive Systems – an Approach to Emergent Mapping

If maps are conceived as representations of reality or as spatially referenced data assemblages, a dilemma is raised by the nature of Indigenous knowledge traditions and multiple ontologies. How can differing knowledge traditions, differing ways of mapping be enabled to work together without subsumption into one common or universal ontology? The paper explores one way of handling this dilemma by reconceiving mapping and knowing performatively and hodologically. It is argued that one way in which differing knowledge traditions can interact and be mutually interrogated is by creating a database structured as distributed knowledge and emulating a complex adaptive system. Through focusing on the encounters, tensions and cooperations between traditions and utilising the concept of cognitive trails‐ the creation of knowledge by movement through the natural and intellectual environment – the socially distributed performative dimensions of differing modes of spatially organised knowledges can then be held in a dialogical tension that enables emergent mapping.     

Non-dietary Marks in the Anterior Dentition of the Krapina Neanderthals

A sample of 82 anterior teeth from Krapina (Croatia) was studied using a light binocular microscope and a scanning electron microscope to document the presence of non-dietary dental scratches. The patterns of distribution, location and orientation of these marks suggest two different aetiologies: scratches on the labial-occlusal enamel border appear to be related to the action of clenching abrasive materials between teeth, while the scratches primarily in the centre of the labial face correspond to cutmarks as described by other researchers. These scratches may have been produced when flake tools involved in processing materials held between the anterior teeth came into contact with the labial enamel face. Alternatively, they may simply reflect some consistent operation which pulled hard objects across the labial surfaces of the anterior teeth. In either case, the marks on the central face of the labial surface provide evidence for manual dexterity in the Neanderthals. Of the seven Krapina individuals which show a predominant pattern, one shows a pattern of left oblique marks, while six provide evidence of right-handedness. Coupled with other Neanderthal or Upper Pleistocene individuals with these patterns, right-handedness is the dominant pattern in 90 per cent of the documented cases. One complicating factor in the analysis of these scratches in the Krapina hominids is that marks of a similar morphology are found in several anterior teeth of Ursus spelaeus from the site. While resembling the marks on the hominid incisors, the scratches on the bears lack a dominant orientation on the labial face and appear to be more variable in their widths. Despite the occurrence of some similarities in the enamel scratches between ursids and hominids at Krapina, the study of anterior dental marks provides information about manipulative activities which are unique to ancient humans. © 1997 by John Wiley & Sons, Ltd.

Supreme Court Advocacy in the Early Nineteenth Century

The early nineteenth century was transformative of the Supreme Court's practices. Yet understanding those fundamental changes requires some appreciation of practice before the Court in the late eighteenth century, and the developments in the early nineteenth century produced changes in the Court's practices that are still felt today. In this first half-century or so of the Court's existence, more dramatic developments and changes occurred in oral argument practice than in any other period of the Court's history. ¹     

Greetings from the cybercaliphate: some notes on homeland insecurity

One of the paradoxical effects of the 7 July bombings in London was to expose the ambivalence in the British government's attempt to wage war on terror by forcefully prosecuting war against those who resort to jihad abroad, actively participating in coalitions of the willing whether in Afghanistan or Iraq, while affording some of Islamism's key ideologists and strategists a high degree of latitude in the United Kingdom itself. This indicates a number of contradictions in official policy that simultaneously recognizes the globalized threat from violent Islamic militancy while, under the rubric of multiculturalism, tolerating those very strains of Islamist radicalism, some of which draw upon the interdependent and transnational character of conflict, to render the UK vulnerable to those very same violent forces. Consequently, the British authorities displayed a studied indifference towards this developing transnational phenomenon both during the 1990s and in some respects even after the London bombings. To explore the curious character of the government's response to the Islamist threat requires the examination of the emergence of this radical ideological understanding and what it entails as a reaction to modernization and secularism in both thought and practice. The analysis explores how government policies often facilitated the non-negotiable identity politics of those promoting a pure, authentic and regenerated Islamic order both in the UK and abroad. This reflected a profound misunderstanding of the growing source and appeal of radical Islam that can be interpreted as a consequence of the slow-motion collision between modernity in its recent globalized form and an Islamic social character, which renders standard western modernization theory, and indeed, the notion of a 'social science' itself, deeply questionable.

Competition and Cooperation in Industrial Clusters: The Implications for Public Policy

Alfred Marshall believed that, while the benefits of clusters resulted from cooperation between firms, competition was an important driving force. In contrast, contemporary theories of clusters place most emphasis on collective action. This article seeks to distinguish processes of competition and cooperation within clusters, through a critical reading of different theoretical approaches. This distinction has important implications for the scale and nature of public policy. An emphasis on competitive processes implies a more macro-economic role for public agencies in seeking to raise investment in innovation while the fostering of cooperation implies measures to support decentralized public-private research collaborations.
