    "Pirates," Stewards, and the Securitization of Global Circulation,

    INTERNATIONAL POLITICAL SOCIOLOGY, Issue 3 2008
    Luis Lobo-Guerrero
    This article is a contribution to the theorization of global maritime circulation as a key category of a global biopolitics of security. It seeks to advance knowledge on the ways in which liberal life is promoted and protected by exacerbating global circulation. It focuses on the security effects of a complex maritime insurance apparatus driven by global insurance in which the Joint War Committee of the Lloyd's Market Association and the International Underwriting Association plays a pivotal role. Through the analysis of the inclusion of the Strait of Malacca in the Lloyd' War List in 2006 under the argument of heightened piracy, it is argued that global maritime insurance performs a special security role, that of stewardship, in securing the circulation of the high seas.

    Records of Bursaphelenchus spp. intercepted in imported packaging wood at Ningbo, China

    FOREST PATHOLOGY, Issue 5 2006
    J. Gu
    Summary From January 2003 to June 2005, samples from 3416 batches of wooden packaging material were inspected for the presence of nematodes in the Ningbo Entry,Exit Inspection and Quarantine Bureau, China. Bursaphelenchus spp. were detected in 202 batches from 25 different countries. The following species were identified on the basis of their morphology and their intergenic transcribed spacer-restriction fragment length polymorphism (ITS-RFLP) patterns: B. xylophilus, B. fungivorus, B. rainulfi, B. hylobianum, B. thailandae, B. mucronatus, B. aberrans, B. lini, B. singaporensis, B. doui, B. conicaudatus, B. vallesianus, B. pinasteri, B. hofmanni and B. arthuri. The most frequently found species were B. mucronatus (57 batches), B. xylophilus (40 batches), B. fungivorus (21 batches), B. rainulfi (19 batches) and B. thailandae (nine batches). The pine wood nematode B. xylophilus was not only found in packaging wood imported from areas where it is known to occur (i.e. The United States of America, Japan, Korea, Hong Kong and Taiwan), but also from countries considered to be free of this dangerous pest (i.e. Brazil, Thailand, Belgium, The Netherlands, Italy and Spain). The occurrence of B. xylophilus in packaging wood from countries regarded as being free of the nematode can most likely be explained by the global circulation of wooden packaging material among infested and non-infested countries. Our findings emphasize the need to fully implement international standards on phytosanitary treatment of packaging wood, in order to prevent further spread of the pine wood nematode, and the need for careful re-examination of the current heat treatment measures. Résumé De Janvier 2003 à Juin 2005, des échantillons de 3416 lots de matériel d'emballage en bois ont été inspectés pour rechercher la présence de nématodes au bureau de quarantaine de Ningbo, en Chine. Des Bursaphelenchus spp. ont été détectés dans 202 lots en provenance de 25 pays différents. Les espèces suivantes ont été identifiées sur la base de leur morphologie et des profils de restriction de l'ITS: B. xylophilus, B. fungivorus, B. rainulfi, B. hylobianum, B. thailandae, B. mucronatus, B. aberrans, B. lini, B. singaporensis, B. doui, B. conicaudatus, B. vallesianus, B. pinasteri, B. hofmanni, et B. arthuri. Les espèces les plus fréquemment trouvées sont B. mucronatus (57 lots), B. xylophilus (40 lots), B. fungivorus (21 lots), B. rainulfi (19 lots) et B. thailandae (9 lots). Le nématode du pin, B. xylophilus, a été trouvé dans du bois d'emballage en provenance non seulement de zones où sa présence est connue (Etats-Unis, Japon, République de Corée, Hongkong et Taïwan) mais aussi de pays considérés comme indemnes de ce redoutable pathogène (Brésil, Thaïlande, Belgique, Pays-Bas, Italie et Espagne). La présence de B. xylophilus dans du bois d'emballage de pays considérés comme indemnes s'explique probablement par la circulation généralisée de matériel d'emballage en bois entre pays infestés ou non. Nos résultats soulignent la nécessité d'appliquer pleinement les normes de traitement phytosanitaire du bois d'emballage, afin d'éviter une plus grande dissémination du nématode du pin, et de réexaminer de façon approfondie les mesures actuelles de traitement thermique. Zusammenfassung Von Januar 2003 bis Juni 2005 wurde im Quarantäne-Inspektionsbüro in Ningbo, China, das Verpackungsholz von 3416 Sendungen nematologisch untersucht. Bursaphelenchus spp. wurden in 202 Sendungen aus 25 verschiedenen Ländern festgestellt. Folgende Arten wurden morphologisch und mit Hilfe der ITS-RFLP-Methode identifiziert: B. xylophilus, B. fungivorus, B. rainulfi, B. hylobianum, B. thailandae, B. mucronatus, B. aberrans, B. lini, B. singaporensis, B. doui, B. conicaudatus, B. vallesianus, B. pinasteri, B. hofmanni, und B. arthuri. Die am häufigsten gefundenen Arten waren B. mucronatus (57 mal), B. xylophilus (40), B. fungivorus (21), B. rainulfi (19) and B. thailandae (9). Der Quarantäneschädling B. xylophilus wurde nicht nur in Verpackungsholz aus Gebieten mit bekannter Verbreitung des Nematoden (USA, Japan, Republik Korea, Hongkong, Taiwan) gefunden, sondern auch aus Ländern, die als frei vom Kiefernholznematoden gelten (Brasilien, Belgien, Niederlande, Italien, Spanien). Die Feststellung von B. xylophilus in Verpackungsholz aus Nichtbefallsländern kann nur durch Zirkulation des Verpackungsholzes zwischen Befalls- und Nichtbefallsländern erklärt werden. Der mittlere prozentuale Anteil der jegliche Nematoden enthaltenden Packholzproben lag im Zeitraum von Januar 2000 bis August 2005 bei 21,3 %; eine klare Tendenz zur Zu- oder Abnahme war während dieser Jahre nicht erkennbar. Die Befunde unterstreichen die Notwendigkeit der strikten Anwendung international erarbeiteter Standards der phytosanitären Behandlung von Verpackungsholz zur Verhinderung der Verschleppung des Kiefernholznematoden und der Überprüfung der Wirksamkeit der zur Zeit angewandten Maßnahmen.

    Thermodynamic optimization of global circulation and climate

    INTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 4 2005
    Adrian Bejan
    Abstract The constructal law of generation of flow structure is used to predict the main features of global circulation and climate. The flow structure is the atmospheric and oceanic circulation. This feature is modelled as convection loops, and added to the earth model as a heat engine heated by the Sun and cooled by the background. It is shown that the dissipation of the power produced by the earth engine can be maximized by selecting the proper balance between the hot and cold zones of the Earth, and by optimizing the thermal conductance of the circulation loops. The optimized features agree with the main characteristics of global circulation and climate. The robustness of these predictions, and the place of the constructal law as a self-standing principle in thermodynamics, are discussed. Copyright © 2005 John Wiley & Sons, Ltd. [source]

    Dynamical mechanisms controlling the vertical redistribution of dust and the thermodynamic structure of the West Saharan atmospheric boundary layer during summer

    ATMOSPHERIC SCIENCE LETTERS, Issue 1 2009
    Juan Cuesta
    Abstract The Saharan atmospheric boundary layer (SABL) plays a significant role in the atmospheric global circulation and directly affects the vertical redistribution of dust originated in the Sahara, the world's largest dust source. Recent measurements have revealed a variety of new dynamical mechanisms that control the structure of the SABL, which are responsible for exchange between the Saharan convective and residual boundary layers. Using new space-borne laser remote sensing data (CALIPSO) and recently published results, we provide an overview of the following known dynamical mechanisms: diurnal vertical mixing, dynamical lifting (density currents and cold air outbreaks) and topographic effects (mountains and albedo anomalies).

    COSMOPOLITANISM, REMEDIATION, AND THE GHOST WORLD OF BOLLYWOOD

    CULTURAL ANTHROPOLOGY, Issue 1 2010
    DAVID NOVAK
    ABSTRACT This essay considers the process of remediation in two North American reproductions of the song-and-dance sequence Jaan Pehechaan Ho from the 1965 "Bollywood" film Gumnaam. The song was used in the opening sequence of the 2001 U.S. independent film Ghost World as a familiar-but-strange object of ironic bewilderment and fantasy for its alienated teenage protagonist Enid. But a decade before Ghost World's release, Jaan Pehechaan Ho had already become the lynchpin of a complex debate about cultural appropriation and multicultural identity for an "alternative" audience in the United States. I illustrate this through an ethnographic analysis of a 1994 videotape of the Heavenly Ten Stems, an experimental rock band in San Francisco, whose performance of the song was disrupted by a group of activists who perceived their reproduction as a mockery. How is Bollywood film song, often itself a kitschy send-up of American popular culture, remediated differently for different projects of reception? How do these cycles of appropriation create overlapping conditions for new identities,whether national, diasporic, or "alternative",within the context of transcultural media consumption? In drawing out the "ghost world" of Bollywood's juxtapositions, I argue that the process of remediation produces more than just new forms and meanings of media, but is constitutive of the cosmopolitan subjects formed in its global circulations.
