The paper describes livestock herding in Shimshal, an indigenous mountain community in Pakistan, with particular attention to the considerations that inform herding decisions. Ethnographic fieldwork in Shimshal reveals two main categories of consideration: instrumental and symbolic. Habermas' theory of communicative action provides a basis for reformulating these categories into a set of conceptually integrated ideal types of resources and for arguing that instrumental and symbolic resources provide motivations toward consumption and conservation, respectively. Two examples of outside interventions to Shimshal's pastoral ecology reveal the limitations of conceptualizing indigenous resource use in purely instrumental terms. The paper concludes with a call to conceptualize indigenous community sustainability in instrumental and symbolic terms.
Cet article traite des troupeaux de bétail à Shimshal, une communauté indigène montagnarde au Pakistan en insistant sur des considérations qui influencent les décisions au sujet des troupeaux. La recherche éthnographique sur le terrain de Shimshal nous révèle deux grandes catégories: instrumental et symbolique. La théorie de l'action communicative d'Habermas fournit une base pour la reformulation des catégories en regroupant d'une façon conceptuelle des types de ressources idéales et permet de constater que les ressources instrumentales et symboli-ques motivent la consommation et la conservation respectivement. Deux exemples d'intervention externe à l'écologie pastorale de Shimshal révèlent les limites de la conceptualisation des ressources indigènes dans les ter-mes instrumentaux. Cet article conclut en suggérant le besoin d'une communauté indigène en termes instrumentaux et symboliques.  相似文献

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 20ème 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.  相似文献

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.  相似文献

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.  相似文献

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.

Twenty‐first‐century political crises stretching from Europe to the Middle East and the Asia–Pacific have undermined the worldview that governed post‐Cold War western thinking about a liberal end of history. This worldview assumed that shared norms and transnational institutions would transform the state based‐order. In this context, the use of force is considered appropriate only for humanitarian ends meeting a set of predetermined axioms laid down in chapter 7 of the UN Charter. Yet for any strategy to be effective—in an international order subject to change—a clear political aim is required, which might deviate from the general rule. Preoccupied with universal postulates, legal normativism has lost sight of the particular. The argument put forth in this article is that the failure of contemporary western foreign policy in the twenty‐first century to address this limitation or to prioritize political ends has led to strategic confusion from Afghanistan to Syria and Ukraine. In this context, it might be useful to reappraise the utility of abstract rationalist approaches to global governance and return instead to an earlier understanding of statecraft that avoided premature generalizations and treated norms as maxims of prudence rather than axioms requiring universal application.  相似文献
