Disorientation: An Introduction

This collection of essays analyses the concept of disorientation. It does so by questioning orientation as norm and disorientation as resistance. This exploration of disorientation does not interpret the disoriented subject as the privileged site of new knowledge, dissident pleasure or social critique. Nor does it propose to embrace disorientation as the invisible norm revealed by the study of supposedly exceptional subjects. Contemplating the concept of disorientation does not mean becoming disoriented, nor does it mean adopting a position of condescending mastery or blind admiration vis-à-vis the disoriented other. We argue that only when it becomes possible to imagine, simultaneously, many incompatible or at least discrepant possible forms of powerful, powerless, desirable and undesirable forms of disorientation, does disorientation become a political tool. We can then imagine disorientation as the name of the constantly evolving relationality between a subject and a conscious or unconscious cultural and political grid. Disorientation is the moment during which a world is produced by the acknowledgment of its dependency on the grid. It is also the moment when some subjects are enabled or disenabled by their relationship to the grid and the world in the absence of others who function as the guardians of the norm. What matters here is the subject's positioning vis-à-vis his or her awareness of dis-re-orientation. The question is not who is lost or who is foreign, who is comfortable or who has colonised, who decides where maps stop and start, but rather what kind of relationality explains who feels dis- or re-oriented

Regional fishery management organisation measures and the imposition of criminal and administrative sanctions in respect of high seas fishing

Doctrinal arguments and two examples illustrating the practice of the Spanish courts highlight two risk factors that can undermine the effectiveness of enforcement actions by States in matters involving high seas fishing. Firstly, the absence from treaty law of clearly defined conduct standards and unequivocal criminal enforcement routes to provide a positive basis for the exercise of extraterritorial criminal jurisdiction. Secondly, the transcendence of individual rights and constitutional principles enshrined in domestic constitutional and European Union law and safeguarded by national courts, and their potential for tension with international fisheries conservation objectives. Through a brief analysis of those tensions, the article leads to a reflection on the relevance of legal security considerations to inform the development of international and regional legal frameworks and decision-making mechanisms for addressing high seas illegal and unregulated fishing

Bioactive Botanics against Pathogenic and Mycotoxigenic Fungi Isolated from Rice

[EN] Cereal fungal contamination causes both economic and human health problems. In the present study, the chemical composition of commercial bay leaf, cinnamon, clove and oregano essential oils, and antifungal activity against three pathogenic fungi isolated from rice, were investigated. Essential oils presented a high percentage of oxygenated components: 78.8% in bay leaf (eucalyptol 52%); 90.5% in clove (eugenol 90%); 92% in cinnamon (eugenol 60% and eugenyl acetate 18.5%); 72% in oregano (carvacrol 50% and thymol 20%). Monoterpenes and sesquiterpenes were: 18% in bay leaf, 9% in clove, 5% in cinnamon, 25% in oregano. Cinnamon, and clove essential oils reduced fungal growth by 70%, 80% and almost 90%. Moreover, there was total inhibition using oregano until the seventeenth day. Oregano, clove and cinnamon oils could provide an alternative for controlling Bipolaris spicifer, Fusarium culmorum and Fusarium sambucinum in stored grains and seeds, so extending their shelf life.Giménez, S.; Rosello Caselles, J.; Santamarina Siurana, MP.

Atlantic Shortfin Mako: Chronicle of a Death Foretold?

This article outlines recent events concerning the conservation and management trajectory of a highly migratory shark species, the shortfin mako (Isurus oxyrinchus), in the North Atlantic, where it has been routinely captured recreationally and as part of commercial fishing operations alongside other species. Noting recent warnings concerning the high mortality of the species in this ocean region, and the threat of imminent population collapse, this article sets out a number of applicable law of the sea provisions, and carries out an evaluation of relevant measures for target and incidental capture species, discussing their applicability to the mako fishery. It also presents an analysis of regional and global governance actions taken to date by the international community and by individual actors, noting a number of shortfalls, and outlining potential responses

In vitro antagonistic activity of Trichoderma harzianum against Fusarium sudanense causing seedling Blight and seed rot on wheat

[EN] Fusarium sudanense is a novel fungus recently isolated from asymptomatic samples of wheat grains in Argentina. The fungus caused symptoms of seedling blight and seed rot on wheat after artificial inoculations. It is known that the production of mycotoxins by pathogens belonging to the Fusarium genus is harmful to human and animal health. Moreover, the warm and humid conditions that are favorable for growth and mycotoxin production of these species put the Argentinian wheat production area at a high risk of mycotoxin contamination with this novel pathogen. The aim of this work was to evaluate the antagonistic effect of Trichoderma harzianum against F. sudanense under in vitro tests at different environmental conditions. Fungi were screened in dual culture at different water activities (alpha(w)) (0.995, 0.98, 0.95, and 0.90) and temperatures (25 and 15 degrees C). The growth rate of the fungi, interaction types, and dominance index were evaluated. Also, the interaction between T. harzianum and F. sudanense was examined by light and cryo-scanning microscopy. T. harzianum suppressed the growth of F. sudanense at 0.995, 0.98, and 0.95 alpha(w) at 25 degrees C and 0.995 and 0.98 alpha(w) at 15 degrees C. Macroscopic study revealed different interaction types between F. sudanense and T. harzianum on dual culture. Dominance on contact where the colonies of T. harzianum overgrew the pathogen was the most common interaction type determined. The competitive capacity of T. harzianum was diminished by decreasing the temperature and alpha(w). At 0.95 alpha(w) and 15 degrees C, both fungi grew slowly, and interaction type "A" was assigned. Microscopic analysis from the interaction zone of dual cultures revealed an attachment of T. harzianum to the F. sudanense hyphae, penetration with or without formation of appressorium-like structures, coiling, plasmolysis, and a veil formation. According to our results, T. harzianum demonstrated capability to antagonize F. sudanense and could be a promising biocontrol agent.This work was supported by the Escuela Tecnica Superior de Ingenieria Agronomica y del Medio Natural (ETSIANM), UPV, Spain, and by Facultad de Ciencias Agrarias y Forestales of the Universidad Nacional de La Plata (grant no. 11A 296), Argentina.Larran, S.; Santamarina Siurana, MP.; Rosello Caselles, J.; Simón, MR.; Perelló, A.
