Feasibility investigation of exposed-core fiber for methadone sensing in biological fluids
No full textIn this paper, we explore numerically the feasibility of a methadone sensor based on novel exposed-core optical fiber coated with a sensitive polymeric layer. The sensor characteristics have been simulated using the Finite Element Method (FEM). In particular, we have shown that the sensor performance can be enhanced, more specifically the minimum detectable concentration of methadone can be reduced, via a suitable choice of the fiber cross section.T.

Cuando las territorialidades se superponen: Producciones tradicionales, agronegocios y proyectos mineros en el Valle del Famatina, La Rioja
No full textEn un contexto de intensificación de las actividades extractivas en América Latina, y Argentina en particular, proponemos explorar sus impactos en el Valle de Famatina, en la provincia de La Rioja (Argentina). La hipótesis de este trabajo es que la extensión de emprendimientos operados bajo lalógica del agronegocio y diversos proyectos de megaminería en la región contienen disputas manifiestas y latentes con las producciones agrícolas tradicionales y los modos de vida locales. En el caso de estudio, la disputa gira en torno a la apropiación material y simbólica de la tierra/territorio y el agua. Para abordar esta problemática proponemos, a través de una revisión bibliográfica, una reconstrucción de los elementos del modelo extractivo, para luego rastrear sus especificidades en el caso propuesto. Este último punto recurre metodológicamente a una combinación de técnicas cuantitativas, principalmente análisis de diversas fuentes estadísticas, y técnicas cualitativas, como la observación participante, entrevistas y análisis de medios periodísticos y comunicados de las organizaciones.En términos generales, una de las conclusiones que arroja el análisis es la presencia superpuesta de disputas en torno al agua protagonizada por las producciones locales, los diferimientosagropecuarios, las diversas empresas mineras que intentaron establecerse en el Valle y la población local.Este artículo fue originalmente publicado como Hadad, G. y Palmisano, T.

Using Ontology Modularization for Efficient Negotiation over Ontology Correspondences in MAS
No full textEfficient agent communication in open and dynamic environments relies on the agents ability to reach a mutual understanding over message exchanges. Such environments are characterized by the existence of heterogeneous agents that commit to different ontologies, with no prior assumptions regarding the use of shared vocabularies. Various approaches have therefore considered how mutually acceptable mappings may be determined dynamically between agents through negotiation. In particular, this paper focusses on the meaning based negotiation approach, proposed by Laera et al [1], that makes use of argumentation in order to select a set of mappings that is deemed acceptable by both agents. However, this process can be highly complex, reaching ?(p)2 complete. Whilst it is non-trivial to reduce this complexity, we have explored the use of ontology modularization as a means of reducing the space of possible concepts over which the agents have to negotiate. In this paper, we propose an approach that combines modularization with argumentation to generate focused domains of discourse to facilitate communication. We empirically demonstrate that we can not only reduce the number of alignments required to reach consensus by an average of 75%, but that in 41% of cases, we can identify those agents that would not be able to fully satisfy the request, without the need for negotiation

No full textPolitical anthropology and social order
No full textIn this article the author discusses the role of democracy in the post-global context. By “post-global” he intends that the grands récits (systems of thought and ideologies) which according to Lyotard were doomed to disappear in the post-modern era are still present and active but that they are not obvious anymore: they work underground within the processes of economic, social, political production. The author proceeds by examining the three principles on which societies order themselves: the sharing and establishment of blood ties – or time ties –, the sharing and establishment of space ties – or territorial ties – and, finally, the sharing of common action such as planning actions for the future. The author argues that democracy is the only form of political organization which is able to guarantee the possibility to these three principles of ordering the world to co-exist in such a way that none of the three principles can survive or prosper at the expense of the other two.
But today this balance is threatened by a new element which sprouts from the third principle – the sharing of common action – in this case, the order of the market: a new transnational order which is also juridical, the order produced by the relations between economic actors becomes juridical.
The State, intended here as expression of the territorial principle of organization of a society, is contractually week in this new context which the author calls the post-global context, and transnational holdings easily colonize the Lebenswelt.
According to the author, it is not possible to practice democracy, to have strength as territorial unit, without the public and visible discussion of other ties, which are not territorial. The practice of assembly dialogue is therefore essential. He further states that democracy is a tension and not a guaranteed condition or state that one can keep to oneself

Dynamic selection of ontological alignments: a space reduction mechanism
No full textEffective communication in open environments relies on the ability of agents to reach a mutual understanding of the exchanged message by reconciling the vocabulary (ontology) used. Various approaches have considered how mutually acceptable mappings between corresponding concepts in the agents' own ontologies may be determined dynamically through argumentation-based negotiation (such as Meaning-based Argumentation). However, the complexity of this process is high, approaching Π2(p)-complete in some cases. As reducing this complexity is non-trivial, we propose the use of ontology modularization as a means of reducing the space over which possible concepts are negotiated. The suitability of different modularization approaches as filtering mechanisms for reducing the negotiation search space is investigated, and a framework that integrates modularization with Meaning-based Argumentation is proposed. We empirically demonstrate that some modularization approaches not only reduce the number of alignments required to reach consensus, but also predict those cases where a service provider is unable to fully satisfy a request, without the need for negotiation
