The Altos de Jalisco region in west central Mexico is the location of the largest concentration of poultry farms. This district has witnessed the emergence of Low Pathogenic H5N2 and the Highly Pathogenic H7N3 Influenza viruses. Eighty counting stations along a 50 km corridor were designated in five ecological environments from water bodies to poultry production facilities. The survey, implemented from fall 2014 to winter 2015, identified 82 species of wild birds where the family Icteridae comprised the most abundant group. A network-theory model provided a value of interaction among the wild bird species in these five environments. The highest ranked species corresponded to the Mexican Great-tailed Grackle and the Barn Swallow ; making those potential hosts for disease transmission of pathogens in the wild bird-poultry interface in the region of Jalisco. These interactions are likely to positively correlate with increased risk factors., Facteurs de risque pour la transmission d’agents de maladies infectieuses dans l’interface oiseaux sauvages -oiseaux commerciaux. étude préliminaire dans la région des altos de Jalisco, Mexique. La région des Altos de Jalisco au Mexique qui se trouve dans la zone centre-occidentale du pays, correspond à la plus grande concentration des fermes avicoles. Ce secteur a été le témoin de l’émergence des virus influenza faiblement pathogène H5N2 et hautement pathogène H7N3. Quatre-vingts points d’évaluation le long d’un couloir de 50 kilomètres ont été réalisés dans cinq environnements écologiques des corps d’eau voisins aux installations productives de volaille. L’enquête, mise en application de l’automne 2014 à l’hiver 2015, a identifié 82 espèces d’oiseaux sauvages où la famille Icteridae a constitué le groupe le plus abondant. Un modèle de théorie des réseaux a fourni une valeur d’interaction parmi les espèces sauvages d’oiseaux dans ces cinq environnements. Les espèces avec les valeurs d’interaction plus hautes ont correspondu au Quiscale à longue queue et à l´Hirondelle rustique permettant de suspecter ces deux espèces en tant que responsables potentiels dans la transmission des agents pathogènes infectieux dans l’interface oiseau sauvages-oiseaux commerciaux dans cette région de Jalisco. Ces interactions permettent de suspecter une corrélation positive avec les facteurs de risque., Valdez-Gomez Hector Enrique, Navarro-Lopez Roberto, Vazquez-Mendoza Laureano Fidelmar, Zalapa-Hernandez Mitzunari, Guerrerro-Hernandez Ignacio, Fonseca-Delgado Victoria, Marquez-Ruiz Miguel Angel, Afonso Claudio L.

The objective of this work is to give time Petri nets a partial order semantics, akin to the nonsequential processes of untimed net systems. To this end a time process of a time Petri net is defined as a traditionally constructed causal process with a valid timing. A timing is a labelling that attaches occurrence times to the events of the process that must satisfy specific validness criteria. The main result of the paper is the bijective correspondence between firing schedules (the classical interleaving semantics of time Petri nets) and linearizations of time processes. The result shows that time processes correctly represent the behavior of the system. Using the definition of validness, an efficient algorithm for checking validness of given timings is derived. Also a sufficient condition is given for when the invalidity of timings for a process can be inferred from its initial subprocess. To compute, e.g. the maximum time separation between two events in a time process an alternative characterization of validness is developed. This definition is used to derive an algorithm for constructing the set of all valid timings for a process. The set of valid timings is presented as sets of alternative linear constraints, which can be used in optimization problems. It is shown that the existence of a valid timing for a given process can be decided in NP time.

Assim, o principal desafio passa a ser como praticar a inovação, e não mais em relação à sua importância. Neste contexto, a literatura (CALIA, 2007; BRITTO, 2002; TERRA; PLONSK, 2006; AMATO NETO, 2005) parece indicar que as redes surgem como uma forma de viabilização das inovações, podendo oferecer as condições necessárias ao seu desenvolvimento. Desta forma, a presente pesquisa tem como objetivo central um aprofundamento na compreensão das redes de transformação. Essas redes são as responsáveis por auxiliar na interligação entre as redes de exploração (criação do conhecimento) e as redes de aplicação (aplicação e utilização do conhecimento). Buscar-se ainda identificar possíveis práticas e ferramentas presentes nas redes de transformação que possam acelerar o processo de inovação. A abordagem metodológica utilizada foi o estudo de caso, realizado em duas empresas do setor químico do interior do estado de São Paulo. Os estudos de caso apresentados foram analisados, segundo o modelo de processo de inovação em redes proposto por Gobbo Júnior e Olsson (2010), que descrevem os tipos de redes abertas, fechadas e de transformação, bem como identificam os tipos de atores presentes na interface entre as redes de exploração e aplicação, sugerindo que a inovação é um processo em rede que ocorre em sentido horário ao modelo apresentado. As pesquisas realizadas nas duas empresas corroboraram com os dados apresentados pelo modelo de inovação proposto por Gobbo Júnior e Olsson (2010), em que foi possível identificar não apenas os atores presentes nas redes de exploração e aplicação, mas também os... The importance of innovation practice by enterprises is already evident in literature (FREEMAN, 1982, HINDMOON, 2008; TAALITA et al., 2006), as an efficient mechanism concerning its development, growt and profit. then, the main challenge is how to practice such innovation, and not its importance anymore. In this context, the literature (CALIA, 2007; BRITTO, 2002; TERRA; PLONSK, 2006; AMATO NETO, 2005), seem to indicate that the networks seem to arise as the feasibility of the innovations offering suitable conditions for its development. In this way, the current research aims mainly to go deeper into the network transformation and comprehension. These networks are responsible for the interlink support, among the network exploration (the knowledge creation), and the network applying (applying and use of knowledge). Yet, it is searched how to identify possible practices and tools in the network transformation, which may accelerate the innovation process. The approach methodology used was a case study help in two interprises in the chemical field within Sao Paulo state. The case studies were examined according to the innovation process model in networks, proposed by Gobbo Junior and Olsson (2010), which describes the types of external, closed and network transformation, and identify the types of actors in the interface between the network exploration and innovation as well, occurring articlockwise compared to the shown model. The two researches help in both enterprises corroborated with data pointed out by the innovation model offered by Gobbo Junior and Olsson (2010), making it possible to identify not only the actors in the exploration and innovation networks but also the intermediate actors related to the process. It was also possible to identify the path of the innovation process in networks by such actors. In the first case, it is was the enterprise which moved along the network, while ...
