This paper examines the actors and activities and the institutional–spatial dynamics that characterize innovation and knowledge processes within the aquaculture industry and its support organizations in the coastal region of Quebec, Canada. It aims to identify the main features and components of such support organizations and their roles in entrepreneurial and knowledge processes. Comparing this Canadian case with the more developed Norwegian innovation system in aquaculture, the paper concludes that the market possibilities for the products of aquaculture are almost the same in Norway and Quebec. However, it is the policy and institutional settings, as well as the historical trajectories of the respective innovation systems, which seem to explain the growth of the aquaculture industry in Norway and its less successful development in Quebec. The paper also investigates the conditions and institutional arrangements that may stimulate the building and development of a more mature aquaculture innovation system support in Quebec's coastal region.  相似文献

Condorcet's classical Enlightenment statement of human progress became an essential element of nineteenth‐ and twentieth‐century consciousness, but by the millennium grand narratives had fallen victim to a disillusioned cultural climate. Now Steven Pinker, like Condorcet drawing on a wide range of contemporary “knowledges,” has reasserted a sweeping narrative of human progress in The Better Angels of Our Nature: Why Violence Has Declined. Mapping a spectacular long‐term decline in person‐on‐person violence and reduction in deaths due to war, Pinker celebrates the spread of a cultural pattern of self‐restraint, sensitivity to human suffering, and recent regard for human rights, due to the modern state and gentle commerce capitalism. For Pinker the human condition has gotten steadily better, the decline of violence is an accomplishment we can savor and an impetus to cherish the forces of civilization and enlightenment that made it possible. Why then are so many so negative about modernity? Citing the psychology of temporal proximity to horrific events and the bad‐news predilection of the media, Pinker ignores the specifically modern and less directly brutal institutionalized forms of violence as well as the profound ambivalence of progress. He decisively demonstrates the drop in certain kinds of violence, but his account becomes strangely ideological, recapitulating key Cold‐War themes—the individual against totalitarianism, the Enlightenment against the counter‐Enlightenment, rationalism and freedom against murderous utopianism—distorting his study in the name of gentle commerce, Marxism, and anti‐Communism.  相似文献

During the 2008 global financial crisis, gold‐backed reserves became a ‘safe haven’ for capital investment, causing gold prices to hit historic highs. Globally, small‐scale gold mining activities proliferated as prices climbed. Along the banks of Ghana's Offin River, abandoned, waterlogged mining pits now stretch for kilometres where agricultural and other land uses recently existed. While small‐scale mining is a right reserved for Ghanaian citizens, many mining sites are foreign‐operated and almost all go unremediated. There is thus a stark tension between Ghanaian minerals laws and environmental regulations and the ongoing transformation of rural landscapes. Based on 112 interviews and long‐term observation in Ghana since 2010, this article untangles the relationships and practices mediating ‘illegal’ foreign mining operations. Shifting subjectivities, performances and practices bring land grabbing into being as state actors weave together legal and extra‐legal domains to facilitate, and profit from, foreign mining. Other officials experience fear and frustration in the face of powerful mining interests, demonstrating the complex workings and conflicts between government actors and agencies. Detailing co‐productions between ‘legal’ and ‘illegal’ domains in official licensing procedures complicates understandings of the state and its role in foreign land grabbing, breaking down the ontological binaries — rational/irrational, official/unofficial — used to uphold an image of state legitimacy and cohesion. Finally, given the spatial extent of small‐scale mining deals and ensuing social and environmental transformations, the authors urge land‐grab scholars not to dismiss the importance of small‐scale deals alongside larger transactions.  相似文献

The genus Umkomasia, a megasporophyll, belonging to the pteridosperms (seed ferns) in the family Umkomasiaceae (Corystospermaceae), is reassessed comprehensively worldwide. All previous records are analysed. Certain fertile structures previously attributed are reclassified. Umkomasia is shown to be restricted to the Triassic of Gondwana where it is associated with the genus Pteruchus, a microsporophyll, and the genus Dicroidium, a vegetative leaf. It is well represented from Argentina, Australia and southern Africa where the Molteno Formation is by far the most comprehensively sampled with eight species described. Two specimens from the upper Permian of India attributed to Umkomasia are reclassified as cf. Arberiopsis sp. A whorled fertile structure from Antarctica, previously assigned to Umkomasia, is reclassified in a new genus as Axsmithia uniramia. Another compression fossil and the permineralized Umkomasia resinosa remain as valid records from Antarctica. The material described as Umkomasia from the Triassic of China is reclassified as Stenorachis asiatica. The Lower Jurassic record from Germany is placed in a new genus as Kirchmuellia franconica. The records of Umkomasia sp. from the Rhaetic of Germany are reclassified as cf. Kirchmuellia sp. and the single specimen from the Jurassic of Libya as genus et sp. indet. The Lower Cretaceous record from Mongolia has been reclassified by other researchers as Doylea mongolica. A pictorial key to Umkomasia species is provided, geographic and stratigraphic distributions are tabulated.  相似文献

This article examines how Maoist theory and practice were imported to France during the 1960s. A syncretic phenomenon, as notions developed in the Chinese cultural context were adapted to the very different Gallic situation, French Maoism proved to be especially influential among students at the École normale supérieure at the rue d’Ulm in Paris, where the Marxist theoretician, Louis Althusser, was teaching. Maoist philosophy facilitated critiques of the Moscow-aligned French Communist Party and its student union; it enabled Althusser's rethinking of the Marxist tradition, and it ultimately provided ammunition for his students’ eventual break with his “theoreticism.” Maoism's fecund contribution to French intellectual culture in the 1960s, helping to lay the groundwork for the events of May 1968, derived principally from its dual theoretical and practical nature. This article highlights two specific Maoist tenants—the inevitably violent nature of revolution and the ersatz-empiricist method of the “investigation”—and suggests how, after 1968, French Maoism ultimately surrendered the former as the latter proved more useful to direct democratic politics.  相似文献

Recent geographical contributions to post‐colonial studies have paid relatively little attention to subterranean spaces as arenas of modern European imperial and colonial expansion and instead have concentrated almost exclusively on examining ‘surface’ landscapes and practices. This article argues that greater critical attention deserves to be paid by geographers to the ‘colonial underground’, not only because mining played a central role in many imperial ventures since the 16th century, but also because closer scrutiny of the vertical dimension can provide new insights into the nature of colonial relations and into the ways in which colonial landscapes were inhabited and given meaning. Drawing on recent literature as well as on documentation from early colonial Peru, the article shows that colonial European engagements with the underground were more varied than most work in human geography suggests and, moreover, that the subterranean cannot exclusively be regarded as a space of colonial domination and exploitation.  相似文献
