    Full Text Available Las actividades productivas generan riesgos antrópicos [1] a mediano y largo plazo. La zona de estudio se ubica en las Parroquias de Pomasqui, San Antonio y Calacalí, donde se han producido riesgos debido a las actividades humanas, en este caso, por la explotación de las canteras para abastecer el mercado de la construcción del Distrito Metropolitano de Quito. La investigación propone determinar los riesgos antrópicos generados por la actividad minera. Los pobladores de la zona identifican que la minería artesanal en sus inicios constituyó una fuente de trabajo, donde sus familias también se involucraban. Actualmente, se observa que en la mayoría de las canteras se utiliza maquinaria especializada y no participan los trabajadores de la zona. Los taludes de las canteras son de 80o y 90o grados, generando amenazas para los trabajadores y moradores de las viviendas aledañas. Uno de los mayores impactos es la contaminación del aire, sin embargo, el suelo y los cursos de agua están siendo afectados por los desperdicios que produce la actividad minera. La población, que está expuesta permanentemente al polvo ocasionado por las canteras y al transporte de material, acusa enfermedades de tipo respiratorio. Así mismo, el ruido ocasionado por el transporte constituye una molestia constante para los pobladores.

    ambiente han aumentado considerablementedesde el inicio de la era industrial. El mercurio se encuentra actualmente en diversos medios y alimentos (especialmente, el pescado en todo el mundo a niveles que afectan adversamente a los seres humanos y la vida silvestre. La actividad del hombre ha generalizado los casos de exposición, contribuyendocon un legado de mercurio en vertederos, los desechos de la minería y los emplazamientos, suelos ysedimentos industriales contaminados. Hasta las regiones donde se registran emisiones mínimas demercurio, como el Ártico, se han visto afectadas debido al transporte transcontinental y mundial delmercurio. Desde el punto de vista toxicológico, existen tres formas de mercurio: elemental, inorgánico (sales demercurio y óxido de mercurio y orgánico. Cada una de estas especies químicas de mercurio poseeespectros diferentes de toxicidad, aunque todas ellas tienen en común su capacidad de inducir cambiosen los sistemas neuronales de los humanos. La minería es una de las actividades económicas más antiguas de la humanidad. No es por nada quese clasifican las épocas prehistóricas según los minerales utilizados: Edad de Piedra, Edad de Bronce,Edad de Hierro.La actividad minera a nivel mundial se desarrolla con diferentes dimensiones; estas sonfundamentalmente tres: gran minería, mediana minería y pequeña minería o minería artesanal. Esta última aparece, especialmente, en los países en desarrollo. Según un informe de la Organización Internacional del Trabajo (OIT del 2004, la minería artesanal a nivelmundial ocupaba directamente a 13 millones de personas (30 % mujeres y 15 % niños e indirectamentedependen de esta actividad 100 millones para subsistir.

    Full Text Available La actividad minera, a partir del caso de la mina Marlin, abre una discusión sobre su pertinencia en el contexto guatemalteco. Desde la perspectiva del Estado la actividad se considera un importante aporte a la economía del país y a las comunidades donde se ubica la explotación; sin embargo, la experiencia de Marlin ha sido un importante foco de conflictividad socioambiental, especialmente porque la actividad ha generado más problemas que soluciones. El presente artículo muestra cómo se distribuyen los costos y beneficios (derivados de la explotación de la mina Marlin entre la empresa, el Estado y las comunidades donde se establece la mina, utilizando para el análisis la perspectiva de la justicia ambiental. Se concluye que para que la empresa mantenga las ganancias actuales, debe trasladar los costos sociales, económicos y ambientales al país y a las comunidades locales.

    2008-12-01

    Full Text Available In the various debates on globalization, it has often been understood as a process that empowers multinational capital vis-à-vis local communities and workers. This paper is an attempt to uncover some alternative effects of globalization, or more precisely, how globalization can also open political spaces for local communities to campaign and negotiate for their livelihoods. Through a case study of the conflicts around mining in Tambogrande, the paper shows how this community managed to stop a mining project that it considered destructive. The study explores the political strategies of narrative construction, and the way the opposition narrative was articulated across scales. The opposition narrative was strategically constructed to draw on the national identification with lemon-based dishes and the international strength of the democratization discourse. The Tambogrande case illustrates how a local community can be empowered by aspects of globalization that enables networking and rescaling of narratives.En los diversos debates sobre globalización, este se ha entendido a menudo, como un proceso que fortalece el capital multinacional en comparación de las comunidades y trabajadores locales. El presente artículo intenta revelar algunos efectos alternativos de la globalización, o más exactamente, de cómo la globalización puede también abrir espacios políticos donde las comunidades locales accionen y negocien su sustento. A través de un estudio de caso sobre los conflictos alrededor del proyecto de explotación minera en Tambogrande, se aborda el como esta comunidad logró evitar un proyecto de explotación minera que consideraba destructivo.El estudio explora las estrategias políticas de la construcción de narrativas, y la manera en que la narrativa de la oposición al proyecto minero fue articulada a través de escalas. Esta narrativa fue construida estratégicamente sobre la base de su identificación con caracteres de identidad

    2017-11-01

    Full Text Available En este trabajo se realizó una recopilación de la zona minera más antigua e importante del Ecuador desde su época precolombina hasta la actualidad. Se recolectaron datos que muestran las concentraciones de algunos metales pesados no esenciales (Hg, Pb, As, Mg, Zn, Cd, en los cantones Zaruma y Portovelo de la provincia de El Oro. Los resultados revelaron que los recorridos de los lugares afectados por estos metales van desde el nacimiento de los ríos Calera, Amarillo y Pindo, a lo largo de la cuenca, hasta llegar al río Puyango, donde se obtiene los valores más bajos de estos elementos, a excepción del Manganeso puesto a que su nivel vuelve a elevarse debido a la presencia mineralógica del bosque petrificado de Puyango. Los datos tomados del FONSAD fueron obtenidos del material procesado de los relaves de molienda y colas de cianuración en el año 2004, los mismos demostraron que las concentraciones de plomo y arsénico superaban los valores límites de referencia para estos metales en los suelos. En otros estudios realizados a los pobladores, se tomaron muestras biológicas (sangre, orina y cabello, y con ello se logró determinar que la mayoría de los habitantes de las poblaciones cercanas a la cuenca del río Puyango, se encuentran envenenados con Hg y Pb en pequeñas cantidades dentro de su organismo.

    Full Text Available Mining is the main economic sector that generates incomes for Ecuador; however, the hard ergonomic work and use of chemicals affect the ecosystem and human health. Heavy metals have specific characteristics of bioaccumulation and bioavailability in the human body by altering the physiology of neuronal synapses, respiratory alveolar membrane, locomotor system and alterations in the genetic system and cell dysplasia. So this study examines the effects on human health of individuals and their relation to mining activities by exposure to certain toxic pollutants as risk factors for miners, population of Portovelo Canton, province of El Oro-Ecuador. This activity is traditionally performed without following biosecurity actions both in the mine, narrow and hot tunnels, in the transport of material, also in processing plants where gold, silver, and other metals are processed becoming constant danger. The results of this study show health problems affecting the locomotor system, nervous system and congenital problems. Its severity depends on the dose, age, time of exposure, ways of exposure and environmental, nutritional and genetic factors.

  12. Moral actor, selfish agent.

    Science.gov (United States)

    Frimer, Jeremy A; Schaefer, Nicola K; Oakes, Harrison

    2014-05-01

    People are motivated to behave selfishly while appearing moral. This tension gives rise to 2 divergently motivated selves. The actor-the watched self-tends to be moral; the agent-the self as executor-tends to be selfish. Three studies present direct evidence of the actor's and agent's distinct motives. To recruit the self-as-actor, we asked people to rate the importance of various goals. To recruit the self-as-agent, we asked people to describe their goals verbally. In Study 1, actors claimed their goals were equally about helping the self and others (viz., moral); agents claimed their goals were primarily about helping the self (viz., selfish). This disparity was evident in both individualist and collectivist cultures, attesting to the universality of the selfish agent. Study 2 compared actors' and agents' motives to those of people role-playing highly prosocial or selfish exemplars. In content (Study 2a) and in the impressions they made on an outside observer (Study 2b), actors' motives were similar to those of the prosocial role-players, whereas agents' motives were similar to those of the selfish role-players. Study 3 accounted for the difference between the actor and agent: Participants claimed that their agent's motives were the more realistic and that their actor's motives were the more idealistic. The selfish agent/moral actor duality may account for why implicit and explicit measures of the same construct diverge, and why feeling watched brings out the better angels of human nature.

  16. El desarrollo de la industria minera sonorense: el retorno a la producción de metales preciosos

    Directory of Open Access Journals (Sweden)

    Alvaro Bracamonte Sierra

    1997-01-01

    Full Text Available En este artículo muestra cómo la historia antigua y reciente del estado de Sonora se halla estrechamente ligada a la explotación de los ricos yacimientos mineros localizados en la entidad: a fines del siglo pasado, la economía sonorense se concentraba primordialmente en la extracción de metales preciosos, en especial el oro y la plata; después de las primeras décadas del presente siglo fueron los metales industriales, en particular el cobre, los que tomaron el liderazgo en este sector y, en consecuencia, del conjunto de actividad económica estatal. La importancia adquirida por la minería se desdibujó paulatinamente a causa de que la agricultura y la industria manufacturera ampliaron sus espacios de participación y consiguieron altas tasas de crecimiento. Sin embargo, el ensayo presenta las características que en la actualidad posee la industria minera, sobre todo en 1995 y 1996. Se observa un febril dinamismo en la exploración y explotación de varios metales que hace recordar sus mejores años. Lo diferente de este repunte, por una parte, es que los metales preciosos encabezan la expansión y, por otro lado, que el financiamiento de los nuevos proyectos es mayoritariamente la inversión extranjera. Una vez desarrollados estos puntos se concluye que el nuevo boom de la minería sonorense se distingue por estar conformando una estructura de la producción minera donde lo que destaca es la tendencia menos nacional y más vulnerable a los caprichos del ciclo económico internacional.

    Full Text Available La comarca que conocemos como la Cuenca Minera de Ríotinto comprende una extensión de 453,9 km , y de ella forman parte siete municipios: Zalamea (3.948 ha., El Campillo (2.850 ha., Ríotinto (6.013 ha., Nerva (7.208 ha., Campofrío (896 ha., Berrocal (428 ha. y La Granada (234 ha.. Se podría decir que Zalamea es el núcleo matriz originario de la comarca, pues de su término municipal nacieron , segregándose, Ríotinto (1841, Nerva (1885 y El Campillo (1931. El factor explicativo principal para entender la comarca -su configura­ción espacial, las pautas de poblamiento , su economía, sus formas de articulación social, la mentalidad y peculiaridad es culturales-, es la actividad minera. Se podría decir que la minería ha "creado" la comarca. Las minas fueron vendidas a una compañía británica en 1873, en 1954 pasaron a un consorcio español, desde mediados de los ochenta pertenecen al Holding Ercross (controlado hasta muy recientemente por el grupo KIO y actualmente (enero de 1993 han sido compra das por la corporación norteamericana Free Port Macmoran. Las empresas mineras han sustituido desde fines del siglo XIX, y hasta hace pocas fechas, al estado en las funciones propias de éste en la comarca, teniendo el control absoluto sobre todos los ámbitos de la vida comarcal: vivienda, infraestructuras, comunicaciones, servicios, e incluso sobre la propia sociedad en cuanto a los principales cauces y modos de expresión de la sociabilidad y de la acción sociopolítica, así como en cuanto a los liderazgos y grupos de prestigio y poder.

    Full Text Available La relación inversa entre fecundidad y actividad femenina ha constituido uno de los postulados de la teoría de la transición demográfica y de las formulaciones corrientes. La participación de la mujer en la población activa en España no ha sido continuamente creciente, sino que depende de la coyuntura económica y de contextos sociales específicos. Frente a esta situación fluctuante, el descenso de la fecundidad en la ultima década ha sido significativo. En esta medida, no se puede establecer una correlación entre actividad femenina remunerada y fecundidad, en plazos relativamente cortos. Las sociedades europeas no tienen la misma evolución. En este trabajo se analiza la situación de la actividad femenina y de la fecundidad en España, Francia, Italia y la RFA.

Al respecto se encontró que el 72% de las minas del país corresponden a pequeña minería y dentro de este porcentaje, el 66% es ilegal. Respecto a las minas ilegales se logró determinar que el 39% lleva más de 10 años de explotación minera por lo cual pueden ser consideradas como minería tradicional no legalizada. También se destaca el papel de la mujer y de los grupos étnicos en la pequeña minera. Finalmente, se hacen evidentes los fracasos que ha tenido el Gobierno nacional para legalizar y formalizar esta actividad.

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Este artículo analiza el Código de Minería de 1886 y sus reformas de 1892, considerando de manera particular los impactos que su aplicación ocasionó en el espacio geográfico. Las leyes introdujeron criterios para la demarcación de las propiedades mineras, asegurando el dominio estatal sobre el subsuelo y la obtención de beneficios para el concesionario. La adopción de nuevos principios de Derecho minero resultó funcional a la llegada de los inversionistas extranjeros interesados en la exploración de yacimientos auríferos. El estudio encuentra que la legislación minera se configuró en una interacción dinámica entre actores de diferentes escalas y reestructuró el espacio geográfico de las áreas que contenían yacimientos. Se explora la tensión entre los imperativos del liberalismo económico, a escala nacional, y la expansión del extractivismo industrial, a escala regional, a fines del siglo XIX.

  15. What is a conservation actor?

    Directory of Open Access Journals (Sweden)

    Paul Jepson

    2011-01-01

    Full Text Available As a crisis-oriented discipline, conservation biology needs actions to understand the state of nature and thwart declines in biodiversity. Actors-traditionally individuals, institutions, and collectives-have been central to delivering such goals in practice. However, the definition of actors within the discipline has been narrow and their role in influencing conservation outcomes inadequately conceptualised. In this paper, we examine the question ′What is a conservation actor?′ Who or what creates the capacity to influence conservation values and actions? Drawing from theoretical developments in Actor-Network Theory and collective governance, we argue that the concept of an actor in conservation biology should be broadened to include non-humans, such as species and devices, because they have the agency and ability to influence project goals and outcomes. We illustrate this through four examples: the Asian elephant, International Union for Conservation of Nature red lists, the High Conservation Value approach, and an Integrated Conservation and Development Project. We argue that a broader conceptualisation of actors in conservation biology will produce new forms of understanding that could open up new areas of conservation research, enhance practice and draw attention to spheres of conservation activity that might require stronger oversight and governance.

  16. Efficient Actor Recovery Paradigm for Wireless Sensor and Actor Networks.

    Science.gov (United States)

    Mahjoub, Reem K; Elleithy, Khaled

    2017-04-14

    The actor nodes are the spine of wireless sensor and actor networks (WSANs) that collaborate to perform a specific task in an unverified and uneven environment. Thus, there is a possibility of high failure rate in such unfriendly scenarios due to several factors such as power consumption of devices, electronic circuit failure, software errors in nodes or physical impairment of the actor nodes and inter-actor connectivity problem. Therefore, it is extremely important to discover the failure of a cut-vertex actor and network-disjoint in order to improve the Quality-of-Service (QoS). In this paper, we propose an Efficient Actor Recovery (EAR) paradigm to guarantee the contention-free traffic-forwarding capacity. The EAR paradigm consists of a Node Monitoring and Critical Node Detection (NMCND) algorithm that monitors the activities of the nodes to determine the critical node. In addition, it replaces the critical node with backup node prior to complete node-failure which helps balancing the network performance. The packets are handled using Network Integration and Message Forwarding (NIMF) algorithm that determines the source of forwarding the packets; either from actor or sensor. This decision-making capability of the algorithm controls the packet forwarding rate to maintain the network for a longer time. Furthermore, for handling the proper routing strategy, Priority-Based Routing for Node Failure Avoidance (PRNFA) algorithm is deployed to decide the priority of the packets to be forwarded based on the significance of information available in the packet. To validate the effectiveness of the proposed EAR paradigm, the proposed algorithms were tested using OMNET++ simulation.

    Full Text Available INTRODUÇÃO: Com o aumento da quantidade de dados armazenados na prática da Fisioterapia e da área de saúde em geral, amplia-se, também, a possibilidade de obtenção de informações importantes no apoio ao processo decisório dos profissionais de saúde. Porém, muitas vezes, o volume de dados gerados é tão grande que dificulta sua utilização, demandando processos mais sofisticados para a manipulação de tais dados. OBJETIVO: Este artigo se propõe a apresentar e discutir o potencial de utilização do processo KDD sobre um conjunto de dados de acompanhamento fisioterapêutico de pacientes, bem como sua utilidade na tomada de decisões terapêuticas ou profiláticas. METODOLOGIA: Selecionou-se um subconjunto de dados, referentes a prontuários disponíveis em uma clínica de fisioterapia, do qual foram extraídos três grandes grupos-alvo de tarefas de Mineração de Dados: associação, classificação e agrupamento, explicitados no texto. RESULTADOS: Foram extraídos padrões a partir dos dados, de tal forma que se permitisse ao leitor entender passo a passo o processo, ampliando sua compreensão dos resultados obtidos. Foram descobertos padrões em diversos formatos, os quais evidenciaram as possíveis relações entre as variáveis disponíveis. Em seguida, não apenas os padrões foram discutidos, mas, também, a importância da qualidade dos dados coletados. CONCLUSÕES: As etapas de classificação, descoberta de regras de associação e agrupamento dos dados oportunizou melhor entendimento das especificidades de pacientes atendidos pela clínica em questão, ampliando, assim, o conhecimento do profissional na identificação das condutas a serem adotadas.

  9. Self-Recovering Sensor-Actor Networks

    Directory of Open Access Journals (Sweden)

    Maryam Kamali

    2010-07-01

    Full Text Available Wireless sensor-actor networks are a recent development of wireless networks where both ordinary sensor nodes and more sophisticated and powerful nodes, called actors, are present. In this paper we formalize a recently introduced algorithm that recovers failed actor communication links via the existing sensor infrastructure. We prove via refinement that the recovery is terminating in a finite number of steps and is distributed, thus self-performed by the actors. Most importantly, we prove that the recovery can be done at different levels, via different types of links, such as direct actor links or indirect links between the actors, in the latter case reusing the wireless infrastructure of sensors. This leads to identifying coordination classes, e.g., for delegating the most security sensitive coordination to the direct actor-actor coordination links, the least real-time constrained coordination to indirect links, and the safety critical coordination to both direct actor links and indirect sensor paths between actors. Our formalization is done using the theorem prover in the RODIN platform.

    Full Text Available The argument that the minimization of the dysfunctional consequences of organizational politics is no longer dependent on self-equilibrating mechanism remains valid. This inquiry is therefore framed with a view to establishing suitable strategies for managing political actors. There is a nexus between the diagnosis typology of political actors and the qualitative classes of political actors and their management strategies. In the management of mixed blessing, supportive, non-supportive and marginal political actors; collaborative, involvement, defensive and information strategies respectively were found suitable. This research is based on existing theoretical knowledge on organizational politics and stakeholders management. Data was collected from the literature by means of critical analysis and dialectic reflection on the emerging themes. The study will enhance capability in contexts where the scientific management of political actors is yet to be exemplified.

These changes involve a deep transformation of work and technic systems and organizations distinctly differents from those which appear defined by “endogenous” thesis (Smith’s version and Kaldor law. In new prototypes, turning to automatic and telecommunication systems as well as to a relational, cognitive and linguistic productive forms, knowledge raises as capital productive force.

No obstante, los resultados muestran que no se ha logrado el bienestar planeado. La actividad como estrategia para disminuir la pobreza ha fracasado porque la sociedad local no tiene acceso a los beneficios prometidos. A pesar de este hecho, la actividad tiene todas las posibilidades de catalizar estrategias que permitan a los actores locales reconstruir su proyecto de vida. En el siguiente trabajo se propone la Animación Turística como herramienta pedagógica, no sólo para la construcción del diálogo de saberes, sino también como catalizador de los procesos de concientización del turista sobre la necesidad planetaria de ser un turista solidario y respetuoso de la sociedad y del ecosistema del territorio, denominado "destino".

    Full Text Available OBJETIVO: Analizar cómo se manifiesta la inequidad de género en contextos de pobreza en diferentes escenarios de riesgo ambiental en México. MÉTODOS: Diseño cualitativo basado en seis grupos de discusión y 54 entrevistas en profundidad con mujeres de seis comunidades expuestas, dos al manganeso ambiental en un distrito minero, dos en un corredor industrial y dos aledañas a un relleno sanitario. Se llevó a cabo una revisión documental de los estudios ambientales y de salud realizados en cada zona para relacionarlos con la visión que las mujeres tienen del problema. RESULTADOS: En los tres casos de estudio, por los papeles de género, las mujeres permanecen en el hogar y realizan el trabajo doméstico y, como consecuencia, su exposición ambiental es intensa cuando llevan a cabo sus tareas cotidianas, como la limpieza de la vivienda. Se comprobó que los resultados de las entrevistas y de los grupos de discusión guardan relación con los de los estudios epidemiológicos. En el caso del distrito minero, lo que perciben las mujeres concuerda con lo que se señala en los estudios sobre los efectos cognitivos adversos por exposición al manganeso. En los tres casos, las mujeres tienen serias limitaciones de participación política en la gestión del riesgo ambiental. CONCLUSIONES: Por las condiciones de inequidad, las mujeres están muy expuestas a los riesgos ambientales para la salud y su participación social en la solución de los problemas ambientales es muy limitada. Estos resultados tienen implicaciones para las políticas sociales y ambientales en las zonas estudiadas, especialmente respecto a la evaluación, gestión y comunicación de los riesgos.

    Girotto, Vittorio; Ferrante, Donatella; Pighin, Stefania; Gonzalez, Michel

    2007-06-01

    How do individuals think counterfactually about the outcomes of their decisions? Most previous studies have investigated how readers think about fictional stories, rather than how actors think about events they have actually experienced. We assumed that differences in individuals' roles (actor vs. reader) can make different information available, which in turn can affect counterfactual thinking. Hence, we predicted an effect of role on postdecisional counterfactual thinking. Reporting the results of eight studies, we show that readers undo the negative outcome of a story by undoing the protagonist's choice to tackle a given problem, rather than the protagonist's unsuccessful attempt to solve it. But actors who make the same choice and experience the same negative outcome as the protagonist undo this outcome by altering features of the problem. We also show that this effect does not depend on motivational factors. These results contradict current accounts of counterfactual thinking and demonstrate the necessity of investigating the counterfactual thoughts of individuals in varied roles.

    Directory of Open Access Journals (Sweden)

    Uribe Salas, José Alfredo

    2011-08-01

    Full Text Available This article studies the business strategies and capacity of small and medium-sized mining enterprises that operated in the Pachuca-Real del Monte mining district in Mexico in the late 19th century. In a regional economic context dominated by the monopoly of the Compañía de Minas Real del Monte y Pachuca, small and medium-sized enterprises managed to obtain advantages from both the silver depreciation in the international currency markets and the Mexican public policies focused precisely on mitigating the fall in the price of silver after 1873. The way that some minor and medium-sized local entrepreneurs injected new life into mining activities in the region, thereby actually benefiting from the international circumstances, is analysed. In sum, it was the small and medium-sized mining companies that supported the productive and business development that characterized the period of mining growth in the district during the dictatorship of President Porfirio Díaz.

    Se estudian las estrategias empresariales y la capacidad de las pequeñas y medianas empresas mineras que operaron en el Distrito de Real del Monte y Pachuca para obtener ventajas relativas tanto de la depreciación de la plata en los mercados internacionales como de las políticas públicas establecidas por los gobiernos mexicanos después de 1873 para paliar la caída del valor argentífero, en un contexto de monopolio minero-metalúrgico promovido por la Compañía de Minas Pachuca y Real del Monte. Se analiza cómo algunos pequeños y medianos empresarios locales dieron nuevos bríos a la actividad minera y cómo se vieron beneficiados con la situación internacional. Se concluye que fueron las pequeñas y medianas empresas las que sustentaron el desarrollo productivo y empresarial que caracterizó el auge minero en la región de estudio durante periodo porfirista en México.

    Directory of Open Access Journals (Sweden)

    Simon Fowler

    2016-08-01

    Full Text Available By requiring co-ordination to take place using explicit message passing instead of relying on shared memory, actor-based programming languages have been shown to be effective tools for building reliable and fault-tolerant distributed systems. Although naturally communication-centric, communication patterns in actor-based applications remain informally specified, meaning that errors in communication are detected late, if at all. Multiparty session types are a formalism to describe, at a global level, the interactions between multiple communicating entities. This article describes the implementation of a prototype framework for monitoring Erlang/OTP gen_server applications against multiparty session types, showing how previous work on multiparty session actors can be adapted to a purely actor-based language, and how monitor violations and termination of session participants can be reported in line with the Erlang mantra of "let it fail". Finally, the framework is used to implement two case studies: an adaptation of a freely-available DNS server, and a chat server.

    Full Text Available La minería aurífera en la región de la Orinoquia colombiana ha tenido un importante crecimiento en los últimos 15 años. Esta actividad se ha convertido en un importante problema de salud pública debido a varios factores como el uso de mercurio durante el proceso de amalgamación del oro, la contaminación del ecosistema y la exposición de la población de la región. El objetivo del presente trabajo fue determinar los niveles de mercurio en cabello y sangre en una población minera del departamento del Guainía y la percepción que tiene dicha población del riesgo de usar este elemento. Para tal fin, se encuestaron 78 residentes de la región, de los cuales se obtuvieron 59 muestras de sangre y 61 de cabello. Los resultados indican un precario ambiente laboral y una falta de conocimiento del riesgo ecológico, lo cual permite la contaminación del ecosistema de la Orinoquia. Los individuos perciben la exposición al mercurio como nociva para la salud, aunque sus conocimientos al respecto son inadecuados. Los valores de mercurio en sangre entre los mineros oscilaron entre 6,9 y 168,0 ug/l (promedio=59,16 y entre los individuos indirectamente expuestos fluctuó entre 17,7 y 100,8 ug/l (promedio=53,5. Las concentraciones de mercurio total en cabello oscilaron entre 3,0 y 89,2 ug/g (promedio=26,93 en el grupo de mineros y entre 2,8 y 48,7 ug/g (promedio=22,86 entre los expuestos indirectamente. No se encontraron diferencias significativas en los niveles de mercurio entre los dos grupos estudiados. Se sugieren medidas preventivas y de control de la situación generada por el uso de mercurio en las labores de mineria aurífera de la región.

    Full Text Available In the absence of vegetative cover mining spoils can be subject to leaching, and to erosion by wind and water; as well as being unsightly. Rivers and streams can became clogged or polluted and adjacent areas can be contaminated. Although such wastes can be stabilized by physical means, the alternative is to cover the waste with vegetation. Revegetalion of any reclamation site will occur naturally given time, bu1 usually a more rapid development of vegetation is desirable. So, various approaches to encourage this have been tried. Plant-species selection and establishment techniques are two very important aspects to bear in mind in revegetation approaches. This paper emphasizes the role of successional studies as way to select the promising species as to test the eficacy of hydroseeding as vegetation establishment technique. Results from Mine Fe (Salamanca reveal the mutifactorial character of natural revegetation, and to allow us to identify, the plant species associated with different revegetation stages. This information can be helpful and applied in the future management of this area. Hydroseeding has, al (he beginning, a positive effect to most of the analyzed parameters. This positive effect disappears quite soon. So, hydroseeding do not affect the natural-revegetation dynamics in Mine Fe, but the process is faster with it.En ausencia de cubierta vegetal las áreas mineras sufren procesos de lixiviación y erosión, contaminando y/o colmatando ríos, arroyos, acuíferos y zonas adyacentes, y ocasionan un fuerte impacto visual. Frente a la estabilización de los estériles por medios fisicos, la alternativa es cubrirlos con vegetación. La revegetación natural de escombreras mineras es un proceso muy lento. Puesto que se desea un desarrollo más rápido de la vegetación se han emprendido diversas iniciativas de revegetación.

  8. The moral problem of worse actors

    Full Text Available Individuals and institutions sometimes have morally stringent reasons to not do a given action. For example, an oil company might have morally stringent reasons to refrain from providing revenue to a genocidal regime, or an engineer might have morally stringent reasons to refrain from providing her expertise in the development of weapons of mass destruction. But in some cases, if the agent does not do the action, another actor will do it with much worse consequences. For example, the oil company might know their assets will be bought by a company with worse environmental and labor practices. Or the engineer might know her position will be filled by a more ambitious and amoral engineer. I call this the moral problem of worse actors (MPWA. MPWA gives reason, at least some of the time, to consider otherwise morally impermissible actions permissible or even obligatory. On my account, doing the action in the circumstances of MPWA remains morally objectionable even if permissible or obligatory, and this brings additional moral responsibilities and obligations to the actor. Similarly, not doing the action in the circumstances of MPWA may also bring additional (but different moral responsibilities and obligations. Acknowledging MPWA creates considerable challenges, as many bad actors may appeal to it to justify morally objectionable action. In this paper, I develop a set of strategies for individuals and institutions to handle MPWA. This includes appeals to integrity and the proper attribution of expressive responsibility, regulatory responsibility, and compensatory responsibility. I also address a set of related concerns, including worries about incentivizing would-be bad actors, concerns about epistemic uncertainty, and the problem of mala in se exceptions.

    Full Text Available Resumo: A tragédia do rompimento da barragem de Fundão, considerado como o pior desastre socioambiental do país, ocorrida no município de Mariana, no distrito de Bento Rodrigues, em Minas Gerais, no dia 05 de novembro de 2015, por volta das 16 horas, instiga a investigação científica em várias áreas do conhecimento. Este trabalho busca contribuir para o debate sobre os vazios institucionais nas políticas públicas ambientais que incidem no setor econômico minerário. Associado a este objetivo, propõe uma reflexão numa perspectiva pluridimensional acerca da promoção de um alinhamento estratégico entre os atores que compõem o cenário da extração de minérios, a partir do rompimento da barragem de Fundão. Foi utilizada a análise hermenêutico-dialética e fez-se uma análise qualitativa, a partir de dois níveis de interpretação: o campo das determinações fundamentais (o contexto sócio-histórico e o encontro dos fatos empíricos. Foi realizada uma pesquisa documental. Verificou-se que as atividades minerárias evidenciam a existência de muitos vazios institucionais, desde a concepção de projetos até a sua execução. Evidenciou-se que o sistema jurídico atual não abarca a complexidade que o impacto socioambiental do desastre da barragem de Fundão provocou. A omissão da participação da comunidade local nos processos de licenciamento ambiental da mineração também está associada a vazios institucionais.   Palavras-chave: Mineração; Barragem de rejeito de Fundão; Vazios institucionais; Gestão de impactos sociais.    

  10. Simulation of the Mineração Serra Grande Industrial Grinding Circuit

    Thiago Oliveira Nunan

    Full Text Available Abstract Increasing throughput during the mining cycle operation frequently generates significant capital gains for a company. However, it is necessary to evaluate plant capacity and expand it for obtaining the required throughput increase. Therefore, studies including different scenarios, installation of new equipment and/or optimization of existing ones are required. This study describes the sampling methodology, sample characterization, modeling and simulation of Mineração Serra Grande industrial grinding circuit, an AngloGold Ashanti company, located in Crixás, State of Goiás, Brazil. The studied scenarios were: (1 adding a third ball mill in series with existing two ball mills, (2 adding a third ball mill in parallel with existing mills, (3 adding a vertical mill in series with existing mills and (4 adding high pressure grinding rolls to existing mills. The four simulations were carried out for designing the respective circuit, assessing the interference with existing equipment and installations, as well as comparing the energy consumption among the selected expansion alternatives. Apart from the HPGR alternative, all other three simulations resulted in the required P80 and capacity. Among the three selected simulations, the Vertimill alternative showed the smallest installed power.

    Highlights: • Waters have a meteoric origin even in samples located near the shore. • Marine infiltration only takes place in the deepest layers. • Sulfate enrichment was caused by oxidative dissolution of pyrite by ferric iron. - Abstract: The objective of this work was to evaluate processes affecting waters from Portman Bay by way of stable isotopic analysis, particularly H and O stable isotopes from water and S and O from dissolved sulfates. In addition, surface waters from Sierra Minera were examined for the purpose of determining if these waters are affected by similar processes. The results obtained indicate that Portman Bay waters are meteoric, and marine infiltration only takes place in the deepest layers near the shore or if water remains stagnated in sediments with low permeability. The main source of sulfate was the oxidation of sulfides, resulting in the liberation of acid, sulfate and metals. In order to assess the mechanism responsible for sulfide oxidation, the stoichiometric isotope balance model and the general isotope balance model were tested, suggesting that the oxidation via Fe 3+ was predominant in the surface, and controlled by Acidithiobacillus ferrooxidans, while at depth, sulfate reduction occurred

    2016-11-01

    Full Text Available African Initiated Churches (AICs are not yet recognised as relevant actors of community development interventions. While it has been acknowledged that many of them provide coping mechanisms in adverse environments, support in social transformation and social capital, little information is available on their role as development actors. In this article, we evaluate the potential of AICs as partners of international development agencies for community development. We draw on interviews and focus group discussions with leaders of various AICs conducted in South Africa in February and March 2016. In particular, we examine the churches’ understanding of development, their view on the separation of spiritual and development activities and their priorities. Moreover, we outline the development activities which they are currently engaged in and analyse the structures they have in place to do so. Our findings indicate that AICs are increasingly active in community development and offer various entry points for possible cooperation.

  8. Neoliberalism and political actors in contemporary Argentina

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available In this paper we set out a critical reading of the literature on political neoliberal actors in Argentina. We consider that the concentration of these studies in the national level has to do with a definition of neoliberalism as a set of economical and structural macro politics. We propose to define neoliberalism as a technology of government that intends to hegemonize an “enterprise form” in different social spheres, articulating a symbolical framework in a contingent and contentious way. This insight allows analyzing neoliberal identification processes as heterogeneous trajectories with diverse geographic and temporal scopes.

Por este motivo, se ha desarrollado una propuesta modificatoria del cálculo de regalía minera en base a dos temas principales: (i terminología empleada en la Ley y, (ii establecimiento de la utilidad antes de participaciones y del impuesto a la Renta como base para el cálculo de regalía. Como consecuencia de ello, se estableció como objeto de estudio a todas las empresas minera que pagan regalía; sin embargo, para efectos de la investigación se eligió tres empresas mineras representativas de la mediana y gran minería. Posteriormente se concertaron entrevistas con los gerentes financieros y tributarios de las empresas mencionadas anteriormente así como expertos en el tema de regalía minera; de ello se concluyó que los conceptos de “costo” y “año fiscal correspondiente” mencionados en la Ley generaban ambigüedades, incongruencias y distorsiones contables. Asimismo, las empresas mineras y los expertos coincidieron en que la base vigente para el cálculo de la regalía no es la adecuada para el sector minero puesto que no refleja la situación financiera de las empresas. Por ende, se realizó una propuesta de reformulación de la empleada y una nueva base para el cálculo de la regalía minera basada en el costo de ventas; puesto que, en el costo de ventas se encuentra lo que Kieso y Weygandt (1999 denominaran como “el precio que se paga para obtener el derecho de buscar y encontrar un recursos natural oculto, o el que se paga por una fuente ya descubierta”.

    2018-05-01

    Full Text Available Olive oil consumption has grown substantially in recent years, due in part to the fact that olive oil is healthy. Much of the global olive oil production comes from the rural areas of Jaén in southern Spain. Surrounding this industry, services such as oleotourism are increasing. This paper aims to identify the key elements supporting the development of oleotourism. After a preliminary exploratory analysis of the existing data, a qualitative analysis was performed with actors directly involved in the industry in Jaén. The results helped us define the level of the stakeholders’ involvement and the sustainability, the opportunities, and the constraints affecting oleotourism in this area. The practical implications of this investigation can be useful for governing agencies, local firms, and the tourism industry in support of oleotourism development.

  18. Lone-actor Terrorism and Impulsivity.

    Science.gov (United States)

    Meloy, J Reid; Pollard, Jeffrey W

    2017-11-01

    In some recent cases of lone-actor terrorism, there is evidence the subject acted impulsively, often in response to a triggering event which contained a loss and humiliation. Evidence suggests the subjects acted precipitously, despite planning and preparation carried out in the preceding weeks or months, and their attacks failed to include the often considerable preparation that had been done. The pathway became a runway. The authors recommend the traditional assessment of impulsivity in persons of concern for lone acts of terrorism, as well as other proximal warning behaviors for targeted violence. Both indirect and direct assessment guidelines are proposed, with an emphasis upon self-report, psychological testing, collateral data gathering, and historical records. © 2017 American Academy of Forensic Sciences.

    Trace elements contained in the residues from mining and metallurgical operations are often dispersed by wind and/or water after their disposal. These areas have severe erosion problems caused by water run-off in which soil and mine spoil texture, landscape topography and regional and microclimate play an important role. Water pollution by dissolved metals in mining areas has mainly been associated with the oxidation of sulphide-bearing minerals exposed to weathering conditions, resulting in low quality effluents of acidic pH and containing a high level of dissolved metals. The studied area, Sierra Minera, is close to the mining region of La Unión (Murcia, SE Spain). This area constituted an important mining centre for more than 2500 years, ceasing activity in 1991. The ore deposits of this zone have iron, lead and zinc as the main metal components. Studied area showed a lot of contaminations sources, formed by mining steriles, waste piles and foundry residues. As a consequence of the long period of mining activity, large volumes of wastes were generated during the mineral concentration and smelting processes. Historically, these wastes were dumped into watercourses, filling riverbeds and contaminating their surroundings. 40 sediment samples were collected from the area affected by mining exploitations, and at increasing distances from the contamination sources in 4 zones In addition, 36 surficial water samples were collected after a rain episode The Zn and Fe content was determined by flame atomic absorption spectrometry (FAAS). The Pb and Cd content was determined by electrothermal atomization atomic absorption spectrometry (ETAAS). The As content was measured by atomic fluorescence spectrometry using an automated continuous flow hydride generation spectrometer and Al content was determined by ICP-MS. Mineralogical composition of the samples was made by X Ray Diffraction (XRD) analysis using Cu-Kα radiation with a PW3040 Philips Diffractometer. Zone A: Water

    Full Text Available Se analiza el concepto de "actores claves" en la generación de políticas ambientales. Independientemente de la definición de actor social que se maneje, el asumir la existencia de actores claves ofrece limitaciones conceptuales y prácticas, ya que éstos son coyunturales a cada situación específica. Todos pueden ser actores claves en generar políticas ambientales cumpliendo papeles diferenciales. Como alternativa se utiliza el término de "actores destacados" y se revisan aspectos sobresalientes de varios de ellos en América Latina. Seguidamente se postula que el análisis se debe centrar en los escenarios sociales donde esos actores se pueden manifestar. Se ofrece una distinción preliminar de escenarios que permite integrar a nuevos y viejos movimientos sociales y establecer relaciones de articulación y equivalencia.The concept of "key actors" in the field of environmental politics is analyzed. Beyond the definition of social actor, the assumption of the existence of key actors implies conceptual and practical limitations, as it depends of each specific situation. Everyone could be a key actor under differential roles in the generation of environmental politics. As an alternative, the term "noteworthy actors" is used and a brief review of them in Latin America is presented. The relevant question should address the social scenarios from where these actors can express themselves. A preliminary distinction of scenarios is presented, in which old and new social movements could be integrated and relationships of articulation and equivalence could be established.

  8. International Political Actorness of the European Union: Evaluation Criteria

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available The European Union is a completely new international entity which is hard to evaluate using traditional criteria of political actorness. Its active international presence stimulates the modeling of international actor features beyond the scope of “state-international organization” scheme. The concept of international actorness serves as a starting point for the development of appropriate analytical model. Unlike the traditional state-centered approaches which define an international actor through its affiliation witch the international system, this concept operates at the internal level of international entity and at the international structure level. Furthermore, both of these levels are treated as ontologically neutral and mutually constitutive. This basic theoretical scheme is used for elaboration of evaluation criteria of political actorness. The proposed system of criteria is based on drawing, synthesizing and developing the main writings on “new international actors” since the times of classic work by Carol A. Cosgrove and Kenneth J. Twitchett. The key elements of actorness assessed in this article include defining of capacity to act on the global scene as well as the acceptance by other actors and by international system as a whole. At the internal level, the EU’s actor capacity is measured by assessing its core elements ranging from core aspects, such as autonomy, authority, actor capability, coherence and cohesion to identity aspects. On the external level, the decisive criteria are recognition and acceptance by others which reflect expectations and perceptions of the EU. The proposed approach of evaluating the international actorness enables us to consider the political activity of the EU on the basis of coordinated system of interaction between the variables of international and domestic levels of the analysis. Furthermore, this contributes to the development of cumulative, coherent, and comprehensive theory of international

    Full Text Available Public-Private Partnerships (PPPs have emerged along with the growing role of corporations in global development. One of the largest forms of PPP today is the UN Global Compact. The UN Global Compact involves of companies, NGOs, IGOs and state governments. All of them are trying to realize globalization with a more humanist face with attention to the protection of human rights, environment, labor standards and anti-corruption. Engaging private actors in global governance, The UN Global Compact raises many issues such as power, authority, and legitimacy. The effort to tackle it all is to increase PPP accountability. This research seeks to describe what efforts can be made to enhance private accountability within the international regime. The research undertaken is a descriptive study, focuses on public-private partnerships in the UN Global Compact regime. The study found that there were two attempts that could be done. First, by involving the stakeholders in the development of procedures, mechanisms, reporting and monitoring associated with trying to improve the company’s reputation. Second, by looking at corporate relations as agent and UN Global Compact as principal in principal-agent relation in the international regime.

    2018-04-05

    This paper addresses the problem of spatiotemporal localization of actions in videos. Compared to leading approaches, which all learn to localize based on carefully annotated boxes on training video frames, we adhere to a weakly-supervised solution that only requires a video class label. We introduce an actor-supervised architecture that exploits the inherent compositionality of actions in terms of actor transformations, to localize actions. We make two contributions. First, we propose actor proposals derived from a detector for human and non-human actors intended for images, which is linked over time by Siamese similarity matching to account for actor deformations. Second, we propose an actor-based attention mechanism that enables the localization of the actions from action class labels and actor proposals and is end-to-end trainable. Experiments on three human and non-human action datasets show actor supervision is state-of-the-art for weakly-supervised action localization and is even competitive to some fully-supervised alternatives.

    2015-02-01

    We test whether significant differences in mental illness exist in a matched sample of lone- and group-based terrorists. We then test whether there are distinct behavioral differences between lone-actor terrorists with and without mental illness. We then stratify our sample across a range of diagnoses and again test whether significant differences exist. We conduct a series of bivariate, multivariate, and multinomial statistical tests using a unique dataset of 119 lone-actor terrorists and a matched sample of group-based terrorists. The odds of a lone-actor terrorist having a mental illness is 13.49 times higher than the odds of a group actor having a mental illness. Lone actors who were mentally ill were 18.07 times more likely to have a spouse or partner who was involved in a wider movement than those without a history of mental illness. Those with a mental illness were more likely to have a proximate upcoming life change, more likely to have been a recent victim of prejudice, and experienced proximate and chronic stress. The results identify behaviors and traits that security agencies can utilize to monitor and prevent lone-actor terrorism events. The correlated behaviors provide an image of how risk can crystalize within the individual offender and that our understanding of lone-actor terrorism should be multivariate in nature.

  6. Using attractiveness model for actors ranking in social media networks.

    Qasem, Ziyaad; Jansen, Marc; Hecking, Tobias; Hoppe, H Ulrich

    2017-01-01

    Influential actors detection in social media such as Twitter or Facebook can play a major role in gathering opinions on particular topics, improving the marketing efficiency, predicting the trends, etc. This work aims to extend our formally defined T measure to present a new measure aiming to recognize the actor's influence by the strength of attracting new important actors into a networked community. Therefore, we propose a model of the actor's influence based on the attractiveness of the actor in relation to the number of other attractors with whom he/she has established connections over time. Using an empirically collected social network for the underlying graph, we have applied the above-mentioned measure of influence in order to determine optimal seeds in a simulation of influence maximization. We study our extended measure in the context of information diffusion because this measure is based on a model of actors who attract others to be active members in a community. This corresponds to the idea of the IC simulation model which is used to identify the most important spreaders in a set of actors.

La leche materna es esencial para el desarrollo del ser humano, pero puede contener sustancias tóxicas provenientes de la contaminación ambiental, especialmente en las áreas mineras.Objetivo. Determinar la prevalencia de la contaminación con mercurio de la leche materna de mujeres lactantes residentes en los municipios con explotación minera de oro.Materiales y métodos. Se hizo un estudio transversal de 150 madres lactantes de cuatro municipios mineros de Antioquia (El Bagre, Segovia, Remedios y Zaragoza), a quienes se les hizo una encuesta sobre factores sociodemográficos, ocupacionales y ambientales relacionados con el mercurio, y se les tomaron muestras de leche materna, de orina y de cabello. Se calculó el promedio de la concentración de mercurio y las prevalencias municipales de contaminación.Resultados. El promedio de la concentración de mercurio en la leche materna fue de 2,5 (± desviación estándar 9,2) μg/L. La prevalencia de muestras de leche materna con niveles altos de mercurio fue de 11,7 %.Conclusión. En este estudio se evidencia un grave problema en las regiones mineras auríferas de Antioquia por el efecto de la contaminación con mercurio en sectores de la población más vulnerable.

  10. Trail-Based Search for Efficient Event Report to Mobile Actors in Wireless Sensor and Actor Networks.

    Xu, Zhezhuang; Liu, Guanglun; Yan, Haotian; Cheng, Bin; Lin, Feilong

    2017-10-27

    In wireless sensor and actor networks, when an event is detected, the sensor node needs to transmit an event report to inform the actor. Since the actor moves in the network to execute missions, its location is always unavailable to the sensor nodes. A popular solution is the search strategy that can forward the data to a node without its location information. However, most existing works have not considered the mobility of the node, and thus generate significant energy consumption or transmission delay. In this paper, we propose the trail-based search (TS) strategy that takes advantage of actor's mobility to improve the search efficiency. The main idea of TS is that, when the actor moves in the network, it can leave its trail composed of continuous footprints. The search packet with the event report is transmitted in the network to search the actor or its footprints. Once an effective footprint is discovered, the packet will be forwarded along the trail until it is received by the actor. Moreover, we derive the condition to guarantee the trail connectivity, and propose the redundancy reduction scheme based on TS (TS-R) to reduce nontrivial transmission redundancy that is generated by the trail. The theoretical and numerical analysis is provided to prove the efficiency of TS. Compared with the well-known expanding ring search (ERS), TS significantly reduces the energy consumption and search delay.

    2008-01-01

    To directly use a virtual surface model for action editing and movement control, a general method for creating virtual actor skeleton models and controlling movement is presented. The method includes judging borderlines of the block virtual surface model, calculat-ing the joints, confirming the above block, and using the block hierarchical layout to create the skeleton model. Then, according to the virtual actor model and move-ment restriction, the study focuses on the generation of movement animation using the key frame technique and smoothing movement technique by automatically adding animation and adjusting the actor's pose by different weights on movement amplitude. Finally, movement control of the actor in the virtual environment is implemented by real-time control and path point control, which achieve a good result.

    style actors with receive clauses containing multi-headed message patterns. Patterns may be non-linear and constrained by guards. We provide a number of examples to show the usefulness of the extension. We also explore the design space for multi-headed message matching semantics, for example first-match......The actor model provides high-level concurrency abstractions to coordinate simultaneous computations by message passing. Languages implementing the actor model such as Erlang commonly only support single-headed pattern matching over received messages. We propose and design an extension of Erlang...... and rule priority-match semantics. The various semantics are inspired by the multi-set constraint matching semantics found in Constraint Handling Rules. This provides us with a formal model to study actors with multi-headed message receive patterns. The system can be implemented efficiently and we have...

    Full Text Available Article considers theoretical aspects of soft power concept and its use by various actors in Central Asia. It is noted that scholars as well as practitioners are paying insufficient attention to such key concepts position J. Nye, as an attraction. As a result the efficiency of the use of soft power is significantly reduced. It also shows that the attractiveness is not a universal characteristic. For this reason, attractiveness and hence soft power of different actors are different and aimed at different segments of the population. These differences lead to competition of actors, but they do not reduce interaction in the region to zero-sum game. Specific forms and directions of the soft power of Russia, the U.S., the EU and China in Central Asia are discussed. The article emphasizes that the Central Asian states are not just recipients of soft power of external actors, but also themselves form behavioral strategies that are attractive to others.

  1. Efficient model learning methods for actor-critic control.

    We propose two new actor-critic algorithms for reinforcement learning. Both algorithms use local linear regression (LLR) to learn approximations of the functions involved. A crucial feature of the algorithms is that they also learn a process model, and this, in combination with LLR, provides an efficient policy update for faster learning. The first algorithm uses a novel model-based update rule for the actor parameters. The second algorithm does not use an explicit actor but learns a reference model which represents a desired behavior, from which desired control actions can be calculated using the inverse of the learned process model. The two novel methods and a standard actor-critic algorithm are applied to the pendulum swing-up problem, in which the novel methods achieve faster learning than the standard algorithm.

    2003-01-01

    International audience; In an environment marked by ever-greater international competition, wine sector companies have been seriously questioning the structure of their entire logistics chain. This is due to the emergence of new actors (i.e., large retailers); the diversification of service providers' product offers; and the different rapprochements between actors in this branch. These are all signals that have caused companies to question their logistics strategies as shown in the ISLI survey.

  7. Trail-Based Search for Efficient Event Report to Mobile Actors in Wireless Sensor and Actor Networks †

    In wireless sensor and actor networks, when an event is detected, the sensor node needs to transmit an event report to inform the actor. Since the actor moves in the network to execute missions, its location is always unavailable to the sensor nodes. A popular solution is the search strategy that can forward the data to a node without its location information. However, most existing works have not considered the mobility of the node, and thus generate significant energy consumption or transmission delay. In this paper, we propose the trail-based search (TS) strategy that takes advantage of actor’s mobility to improve the search efficiency. The main idea of TS is that, when the actor moves in the network, it can leave its trail composed of continuous footprints. The search packet with the event report is transmitted in the network to search the actor or its footprints. Once an effective footprint is discovered, the packet will be forwarded along the trail until it is received by the actor. Moreover, we derive the condition to guarantee the trail connectivity, and propose the redundancy reduction scheme based on TS (TS-R) to reduce nontrivial transmission redundancy that is generated by the trail. The theoretical and numerical analysis is provided to prove the efficiency of TS. Compared with the well-known expanding ring search (ERS), TS significantly reduces the energy consumption and search delay. PMID:29077017

  12. The Grand Strategy of Nonstate Actors: Theory and Implications

    Directory of Open Access Journals (Sweden)

    Garrett Pierman

    2015-12-01

    Full Text Available This article addresses the Realist assumption that only actors that are states can be considered to have a strategic culture. The primary issue raised is the question of the ability of non-state actors to have a strategic culture. Al-Qaida is used as a theoretical case study. Ultimately this article rejects the idea of territoriality in strategic culture formulation and calls for academics and policymakers alike to adopt a broader conception of actors on the international, stage. This broader conception of actors would necessitate rich case studies to be done in the future in order to seek an understanding of the strategic culture of the non-state actors which academics and policymakers must deal with in the modern security environment. In particular, the article finds that the assumptions held about al-Qaida thus far are wrong and, in reality, the group has ambitions that are cosmic in nature, which will necessitate change in the strategies used to fight against terrorism.

  18. Burst Diplomacy The Diplomacies of Foreign Policy: Actors and Methods

    Directory of Open Access Journals (Sweden)

    Guillaume Devin

    2010-12-01

    Full Text Available Approaches to diplomacy tend to be restrictive because of an exclusively interstate insight. Indeed, historically, the state monopoly over diplomacy has always been challenged by private actors. Today, it is defied both from the inside because of growing public fragmentation (every ministry tends to lead its own foreign policy; subnational authorities develop their diplomatic relations and from the outside (the business sector and civil society play a growing role on the international scene. This proliferation of actors has transformed diplomatic methods. Beyond the binary division between “old diplomacy” – bilateral, secret and resident – and “new diplomacy” – multilateral, public and itinerant – this article shows that diplomacy has to adapt to number and complexity. Therefore a more global conception need now be considered. Diplomacy today is a system of multiple actors using diverse methods in order to coordinate positions of common interest in a competitive and sometimes hostile environment.

  20. Two-actor conflict with time delay: A dynamical model

    Science.gov (United States)

    Qubbaj, Murad R.; Muneepeerakul, Rachata

    2012-11-01

    Recent mathematical dynamical models of the conflict between two different actors, be they nations, groups, or individuals, have been developed that are capable of predicting various outcomes depending on the chosen feedback strategies, initial conditions, and the previous states of the actors. In addition to these factors, this paper examines the effect of time delayed feedback on the conflict dynamics. Our analysis shows that under certain initial and feedback conditions, a stable neutral equilibrium of conflict may destabilize for some critical values of time delay, and the two actors may evolve to new emotional states. We investigate the results by constructing critical delay surfaces for different sets of parameters and analyzing results from numerical simulations. These results provide new insights regarding conflict and conflict resolution and may help planners in adjusting and assessing their strategic decisions.

  7. Balancing influence between actors in healthcare decision making.

    Kaplan, Robert M; Babad, Yair M

    2011-04-19

    Healthcare costs in most developed countries are not clearly linked to better patient and public health outcomes, but are rather associated with service delivery orientation. In the U.S. this has resulted in large variation in healthcare availability and use, increased cost, reduced employer participation in health insurance programs, and reduced overall population health outcomes. Recent U.S. healthcare reform legislation addresses only some of these issues. Other countries face similar healthcare issues. A major goal of healthcare is to enhance patient health outcomes. This objective is not realized in many countries because incentives and structures are currently not aligned for maximizing population health. The misalignment occurs because of the competing interests between "actors" in healthcare. In a simplified model these are individuals motivated to enhance their own health; enterprises (including a mix of nonprofit, for profit and government providers, payers, and suppliers, etc.) motivated by profit, political, organizational and other forces; and government which often acts in the conflicting roles of a healthcare payer and provider in addition to its role as the representative and protector of the people. An imbalance exists between the actors, due to the resources and information control of the enterprise and government actors relative to the individual and the public. Failure to use effective preventive interventions is perhaps the best example of the misalignment of incentives. We consider the current Pareto efficient balance between the actors in relation to the Pareto frontier, and show that a significant change in the healthcare market requires major changes in the utilities of the enterprise and government actors. A variety of actions are necessary for maximizing population health within the constraints of available resources and the current balance between the actors. These actions include improved transparency of all aspects of medical decision

    2016-01-01

    Private business and philanthropic organizations have played a prominent role in the response to the Ebola outbreak in West Africa and the support of global health governance more broadly. While this involvement may appear to be novel or unprecedented, this article argues that this active role for private actors and philanthropies actually mirrors the historical experience of cross-border health governance in the first half of the twentieth century. By examining the experiences, roles and criticisms of the Rockefeller Foundation's International Health Division and the Bill and Melinda Gates Foundation, it is possible to identify potential opportunities for better cooperation between public and private actors in global health governance.

    2017-01-01

    We introduce an Actor-Critic Ensemble(ACE) method for improving the performance of Deep Deterministic Policy Gradient(DDPG) algorithm. At inference time, our method uses a critic ensemble to select the best action from proposals of multiple actors running in parallel. By having a larger candidate set, our method can avoid actions that have fatal consequences, while staying deterministic.

Foi elaborada uma base de dados, com óbitos infantis analisados pelos Comitês de Prevenção da Mortalidade Infantil de 2000 a 2004, a partir da integração dos Sistemas de Informações de Nascidos Vivos, da Mortalidade e da Investigação da Mortalidade Infantil no Estado do Paraná. O programa da mineração foi o WEKA, de uso livre. A mineração faz busca em banco de dados e fornece regras que devem ser analisadas para transformação em informação útil. Após a mineração, selecionaram-se 4.230 regras, por exemplo: mãe adolescente e peso ao nascer This study aims to identify patterns in maternal and fetal characteristics in the prediction of infant mortality by incorporating innovative techniques like data mining, with proven relevance for public health. A database was developed with infant deaths from 2000 to 2004 analyzed by the Committees for the Prevention of Infant Mortality, based on integration of the Information System on Live Births (SINASC, Mortality Information System, and Investigation of Infant Mortality in the State of Paraná. The data mining software was WEKA (open source. The data mining conducts a database search and provides rules to be analyzed to transform the data into useful information. After mining, 4,230 rules were selected: teenage pregnancy plus birth weight < 2,500g, or post-term birth plus teenage mother with a previous child or intercurrent conditions increase the risk of neonatal death. The results highlight the need for greater attention to teenage mothers, newborns with birth weight < 2,500g, post-term neonates, and infants of mothers with intercurrent conditions, thus corroborating other studies.

    Raquel Olimpia Peláez Ocampo Almeida

    Full Text Available Um procedimento para monitoramento e obtenção de indicadores para avaliação da recuperação ambiental de áreas mineradas foi desenvolvido e testado. Quatro bacias de disposição de rejeitos de mineração de areia industrial revegetadas em épocas distintas constituíram uma cronossequência de 14 anos que possibilitou a observação das mudanças das características físicas e químicas do substrato e o estabelecimento de relações com parâmetros de crescimento da vegetação. Uma análise de covariâncias multivariada entre os indicadores identificou a densidade de solo, teores de matéria orgânica e fósforo e pH como os mais apropriados para avaliar a qualidade do substrato e para atuarem como indicadores de resultados de ações de recuperação das bacias estudadas. Esse procedimento mostrou-se um instrumento de fácil aplicação para o acompanhamento da evolução da recuperação ambiental e para a obtenção de parâmetros quantitativos que facilitem a avaliação dos resultados das ações de recuperação.

    Full Text Available Las mujeres del carbón se hicieron visibles en las protestas del verano de 2012 trascendiendo el ámbito de lo privado y ocupando espacios de protesta y de participación en un sector claramente masculinizado abogando por “salvar” la mina; salvar un trabajo que les identificaba –a ellas y sus familias– como ser y ciudadano de un tejido social fuertemente ligado a una industria en vías de extinción. A través del análisis de discursos, traeremos las voces de las mujeres participantes en la movilización de la minería aragonesa (el origen del ruido y los motivos para el silencio acercándonos a la sociogénesis y el sentido de la protesta. Concluiremos que si bien el contexto de crisis y falta de alternativas laborales están en la base la movilización minera, la acción colectiva femenina fue en primer lugar, expresión de un proceso de reidentificación grupal (en el que mediaban diferentes identidades, entre ellas las de género; en segundo lugar, que la incorporación de la voz femenina a la protesta moldeó discursivamente su expresión, dando centralidad a la dimensión familiar en primer lugar y a la comunitaria después. Y en tercer y último lugar, que estas nuevas formas y narrativas generaron zonas emocionales que activaron y renovaron de modo efectivo y eficaz las solidaridades y reciprocidades articuladoras de la Marea Negra.

    ACToR (Aggregated Computational Toxicology Resource) is a centralized database repository developed by the National Center for Computational Toxicology (NCCT) at the U.S. Environmental Protection Agency (EPA). Free and open source tools were used to compile toxicity data from over 1,950 public sources. ACToR contains chemical structure information and toxicological data for over 558,000 unique chemicals. The database primarily includes data from NCCT research programs, in vivo toxicity data from ToxRef, human exposure data from ExpoCast, high-throughput screening data from ToxCast and high quality chemical structure information from the EPA DSSTox program. The DSSTox database is a chemical structure inventory for the NCCT programs and currently has about 16,000 unique structures. Included are also data from PubChem, ChemSpider, USDA, FDA, NIH and several other public data sources. ACToR has been a resource to various international and national research groups. Most of our recent efforts on ACToR are focused on improving the structural identifiers and Physico-Chemical properties of the chemicals in the database. Organizing this huge collection of data and improving the chemical structure quality of the database has posed some major challenges. Workflows have been developed to process structures, calculate chemical properties and identify relationships between CAS numbers.

En cumplimiento de la normativa europea y nacional, se ha puesto en marcha un programa de vigilancia de la salud de estas personas en la Comunidad de Madrid. Como paso previo se ha reconstruido la cohorte de sujetos expuestos a los que hacer dicho seguimiento. Dicha cohorte está constituida mayoritariamente por hombres (casi el 96,5 %, que son los que en mayor número realizaban actividades de fabricación de productos y piezas con amianto. Sin embargo, el descubrir una mujer afectada por amianto, trabajadora de una empresa sin exposición conocida ni declarada, puso de manifiesto que existen otra serie de actividades relacionadas con dichas fibras, tradicionalmente realizadas por mujeres, y que no habían sido consideradas como de riesgo de amianto, por estar invisibilizadas. Introducir la perspectiva de género en las actividades y programas de las instituciones mejorará la calidad de los mismos, y permitirá la equidad real en el ejercicio del derecho de hombres y mujeres en el ámbito de la salud laboral.

    2004-10-01

    This study determined if actors could portray depressed patients to establish the interrater reliability of raters using the Hamilton Depression Rating Scale (HDRS). Actors portrayed depressed patients using scripts derived from HDRS assessments obtained at three points during treatment. Four experienced raters blindly viewed videotapes of two patients and two actors. They guessed if each interviewee was a patient or an actor and rated the certainty of their guesses. For each interview, they also rated the realism of the portrayal and completed the HDRS. Experienced raters could not distinguish actors and patients better than chance and were equally certain of their right and wrong guesses. Actors and patients received high scores on the realism of their portrayals. The HDRS scores of the actor-patient pairs were correlated. Actors can effectively portray depressed patients. Future studies will determine if actors can accurately portray patients with anxiety and psychosis.

En este trabajo se analizan las posiciones de los diferentes actores sociales, así como las principales fortalezas-debilidades y oportunidades-amenazas que existen en las posibilidades de un planteamiento estratégico de regeneración de la bahía y de la Sierra Minera. Desde una perspectiva socio-ecológica, los análisis realizados ponen de manifiesto las potencialidades para el desarrollo de un turismo ambiental y cultural de este entorno. Sin embargo, las propias debilidades y amenazas podrían superar esas potencialidades si no se lleva a cabo una gestión cuidadosa y una apuesta clara por un modelo de desarrollo sensible en extremo con el patrimonio natural, paisajístico y cultural. Un modelo de turismo ligado a la restauración ambiental y al consenso con los agentes sociales locales debe constituir un elemento básico para la adaptación del territorio como producto turístico, y así debe reflejarse en las futuras decisiones.

  8. Balancing influence between actors in healthcare decision making

    Directory of Open Access Journals (Sweden)

    Babad Yair M

    2011-04-01

    Full Text Available Abstract Background Healthcare costs in most developed countries are not clearly linked to better patient and public health outcomes, but are rather associated with service delivery orientation. In the U.S. this has resulted in large variation in healthcare availability and use, increased cost, reduced employer participation in health insurance programs, and reduced overall population health outcomes. Recent U.S. healthcare reform legislation addresses only some of these issues. Other countries face similar healthcare issues. Discussion A major goal of healthcare is to enhance patient health outcomes. This objective is not realized in many countries because incentives and structures are currently not aligned for maximizing population health. The misalignment occurs because of the competing interests between "actors" in healthcare. In a simplified model these are individuals motivated to enhance their own health; enterprises (including a mix of nonprofit, for profit and government providers, payers, and suppliers, etc. motivated by profit, political, organizational and other forces; and government which often acts in the conflicting roles of a healthcare payer and provider in addition to its role as the representative and protector of the people. An imbalance exists between the actors, due to the resources and information control of the enterprise and government actors relative to the individual and the public. Failure to use effective preventive interventions is perhaps the best example of the misalignment of incentives. We consider the current Pareto efficient balance between the actors in relation to the Pareto frontier, and show that a significant change in the healthcare market requires major changes in the utilities of the enterprise and government actors. Summary A variety of actions are necessary for maximizing population health within the constraints of available resources and the current balance between the actors. These actions include

  9. The legislative actor in the Nobel era: Quo Vadis EU?

    Full Text Available The idea of a political union, as well as an economic union of Europe, beyond free circulation of persons, goods and services, has always been included in the ideals of the building of Europe. However, its de jure formalization only occurs on November 1, 1993, when the Treaty of Maastricht is in force and a new political and strategic actor is in place: the European Union (EU. Since then, literature has "defined" the European Union in order to clearly establish what this UPO - Unidentified Political Object (an expression by Jacques Delors in the 1990s - is or what it can be. One of the ideas which has been a focus of discussion is that of "legislative actor" (Manners, 2001; 2002, which claims that the European Union has progressed towards normativity, both internally as well as externally, to its close neighbors and its relations with the rest of the world. This paper aims to contribute to the discussion on Europe's quality or condition to impose rules. We will begin by systematizing a series of achievements which, according to Manners, lead to the triangle democracy, Human Rights and good governance in the signing of the Treaty of Lisbon on December 13, 2007 and its entering in full force on December 1, 2009. However, this paper does not disregard the fact that the concept "legislative actor" has been (reworked and perfected by its author and other scholars due to criticism and empirical studies and has thus been altered, enhanced and argued against. Therefore, some concepts will be studied whose arguments will allow us to question the internal and external dimension of the actor European Union. We will also explore the symbolic power of the Union in the development of tools and capacity to be acknowledged as an actor able to face current threats and challenges but whose profile may not be different from other actors in international relations. Finally, we will discuss the impact of the EU having been awarded the Nobel Peace Prize in 2012 on

    Full Text Available Los antioxidantes son esenciales en el cuerpo humano para prevenir el daño oxidativo. Estas substancias pueden obtenerse de diversas fuentes como frutas, plantas y hongos. En Guatemala, diversas especies de hongos comestibles son comercializadas y consumidas, sin embargo su actividad antioxidante no ha sido documentada en el país. El objetivo de este estudio fue determinar la actividad antioxidante de extractos acuosos y etanólicos obtenidos de diez especies de basidiomicetos comestibles (Agaricus aff. bisporus, Agaricus brunnescens, Armillariella polymyces, Amanita garabitoana, Boletus edulis, Cantharellus lateritius, Laccaria amethystina, Lactarius deliciosus, Neolentinus ponderosus y Pleurotus ostreatus. Se utilizó un método cualitativo por cromatografía en capa fina (CCF y tres ensayos macrométricos in vitro de cuantificación de fenoles totales, reducción del radical 1,1-difenil-2-pricrilhidrazilo (DPPH y decoloración del radical catiónico del reactivo ácido 2,2’-azinobis-(acido-3-etilbenzotiazolina-6-sulfónico (ABTS. Los extractos acuosos mostraron mayor actividad antioxidante que los extractos etanólicos en todas las técnicas cuantitativas realizadas. La especie que mostró mayor actividad antioxidante en ambos extractos fue B. edulis, cuyos resultados fueron: fenoles totales del extracto acuoso 93.46 ± 18.17 mg/g y 42.70 ± 3.48 mg/g, DPPH CI50 del extracto acuoso 0.93 mg/mL (IC95 0.65-1.28 y 2.75 mg/mL (IC95 2.46-3.07 del extracto etanólico; y en ABTS CI50 del extracto acuoso 0.96 mg/mL (IC95 0.63-1.35 y 4.13 mg/mL (IC95 2.67-5.88 del extracto etanólico. Por la actividad antioxidante de los extractos acuosos de algunas de las especies de basidiomicetos, pueden promoverse como alimentos funcionales.

  11. Action recognition is sensitive to the identity of the actor.

    Ferstl, Ylva; Bülthoff, Heinrich; de la Rosa, Stephan

    2017-09-01

    Recognizing who is carrying out an action is essential for successful human interaction. The cognitive mechanisms underlying this ability are little understood and have been subject of discussions in embodied approaches to action recognition. Here we examine one solution, that visual action recognition processes are at least partly sensitive to the actor's identity. We investigated the dependency between identity information and action related processes by testing the sensitivity of neural action recognition processes to clothing and facial identity information with a behavioral adaptation paradigm. Our results show that action adaptation effects are in fact modulated by both clothing information and the actor's facial identity. The finding demonstrates that neural processes underlying action recognition are sensitive to identity information (including facial identity) and thereby not exclusively tuned to actions. We suggest that such response properties are useful to help humans in knowing who carried out an action. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

  13. Actor proliferation and the fragmentation of violent groups in conflict

    Directory of Open Access Journals (Sweden)

    Caitriona Dowd

    2015-09-01

    Full Text Available This paper proposes a novel application of a measure of actor fragmentation drawn from electoral studies to the growing field of conflict event data. The application facilitates comparison of conflict environments over time and across cases, while enabling researchers to take account of the relative activity levels of diverse actors. Analysis of the measure suggests that a fragmentation index diverges from a simple count of active conflict agents in important instances, including in providing a more accurate measure of dominant and weaker conflict agents, capturing dynamics of escalation and continuation of conflict over time and across country cases, and reflecting the coalescence of conflict agents around dominant conflict cleavages. The findings suggest that future research may benefit from combining measures of the discrete count of groups and their relative activity levels in order to accurately capture evolving conflict dynamics.

  14. APPROACHES TO GLOBAL SECURITY. ACTORS, MANIFESTATIONS AND TENDENCIES

    Directory of Open Access Journals (Sweden)

    Gheorghe MINCULETE

    2013-01-01

    Full Text Available Nowadays, the world seems to be in a transition from the current system founded on the liberal social, economic and political model to a more diverse and heterogeneous model in which the determinant role is played by a number of state and non-state actors. The step from the Western system of cultural, political and predominant economic values to a more diverse and heterogeneous system makes the actors involved defend not only their visions, but also promote their own interests. The differences between visions gain relevance and clarity because the countries supporting them obtain increased power, and that is more than obvious. All this leads to a symmetric allocation of different means, which generates uncertainties and diminishes unilateral actions This transition process impacts global security especially through the asymmetric, unconventional and hybrid risks and threats manifesting worldwide.

  15. Widening the scope? How intermediary actors can shape energy consumption

    DEFF Research Database (Denmark)

    Maneschi, Davide

    2013-01-01

    This paper deals with energy consumption in the residential sector and with the implementation of measures to reduce it. While most research dealing with energy consumption has targeted factors and drivers at the individual user level, more recent works have highlighted collective aspects...... of (energy) consumption, both to explain the resilience of consumption patterns and to identify leverage points for the reduction of energy use. One understudied aspect of this discussion is the way “intermediary” actors – those actors who are neither policy makers, nor users, nor energy providers...... – influence energy consumption. This paper presents a review of the literature on intermediaries, providing an overview of their roles and contextualizing their functions in energy efficiency improvements. The review shows how the concept of intermediaries has been used in research dealing with innovation...

    on the results, these tools must use consistent semantics for the model. Yet, a monolithic semantic model is just as complex as the entity it describes. In order to circumvent this issue, we define a three level semantics giving independent definitions of the functionality of actors, the temporal properties...... of communications, and finally imposing deadlines on the timing of dependent actors. With this approach the semantics is used directly in developing a simulator supporting the nondeterminism of the abstract semantics such that e.g. potential race conditions can be detected. The layers are also planned to underpin...... independent specialized verification tools. The verification task for timed, hybrid systems can thus be divided into the continuous, discrete, and timing domains with automated translation to specialized tools, and this promises better scalability than simulation or model checking of one complex model....

  17. Chinas carbon-intensity target: climate actors and policy developments

    Energy Technology Data Exchange (ETDEWEB)

    Stensdal, Iselin

    2012-11-01

    China has become the largest GHG emitting country, and announced in 2009 its first policy objective measured in carbon emissions. The carbon-intensity target is to reduce the carbon intensity by 40-45 % by 2020 compared to 200 levels. Since then there has been further policy developments in order to attain the reduction carbon intensity and steer China towards a low-carbon development. The 12th 5-year plan (2011-2015) is strong on incentives for reducing China's carbon intensity such as energy conservation measures and the establishment of new market-based mechanisms. While the central government forms the policies, the implementation is dependent on a range of actors. In addition to the climate change bureaucracy, the positive forces and actors on GHG mitigation is presented. All in all, there are promising developments in China for the years to come.(auth)

  18. New market actors: economic social movements and politicized consumers

    Directory of Open Access Journals (Sweden)

    Fátima Portilho

    2009-10-01

    Full Text Available This article presents reflections on new market actors, and economic social movements in particular - that is, those in which actors build a new culture of political action that seeks to reappropriate the economy through their own values. Some examples of this are the movements organized around “solidarity economics”, fair trade, geographic indications, “slow food” and consumer organization. This interface of social movements and the market may be the most marked, differentiated and polemic trait of contemporary political mobilizations. Nonetheless, beyond economic social movements, this article simultaneously emphasizes and problematizes political action within the sphere of individual consumption, that is, that which has been referred to as “political consumption”. Keywords: economic social movements, consumer movements, political consumption.

  5. Counterterrorism in the Russian Arctic: legal framework and central actors

    Directory of Open Access Journals (Sweden)

    Ingvill M. Elgsaas

    2017-12-01

    Full Text Available Russia’s strategic interests in the Arctic coupled with a complex and diffuse terrorist threat has produced a niche topic: Arctic counterterrorism. Arctic counterterrorism is a new and underdeveloped topic that has received only limited attention. This article contributes a discussion of the legal framework and the main actors involved in countering terrorism in the Russian Arctic. The author finds that the legal framework for counterterrorism is extensive yet centered in core documents. Similarly, counterterrorism involves many and varied actors united in a relatively simple and streamlined national system for counterterrorism. Current legal regulation and organisation provide a solid base that may support efficient management of counterterrorism, also in the Arctic. A notable strength is the concentration of coordination responsibilities in the hands of one central actor, the FSB. Another important characteristic is that the system is symmetrical and follows Russia’s federal organisation with coordinating bodies for all regions including those in the Arctic. Counterterrorism legislation is kept up to date and the trend is towards tougher punishments and a wide understanding of terrorist offenses. A potential weak spot is the unclear role of the newly formed National Guard. The uncertainty surrounding the role of the National Guard in the fight against terrorism may challenge the FSB and weaken coordination of the system for counterterrorism in the future.

  6. Environmental assessment for sustainable development: process, actors and practice

    International Nuclear Information System (INIS)

    Andre, P.; Delisle, C.E.; Reveret, J.-P.

    2003-01-01

    Multiple environmental problems afflict our contemporary world and have been the subject of discussions during many international meetings. All declarations resulting from these meetings insist on including environmental problems and on environmental assessment (EA) as an important tool to achieve this. This book aims to reach three objectives. First, it introduces EA to people from different disciplines, and therefore it opens up the perspective of new disciplinary horizons. Second, the authors discuss EA as a socio-political process rather than emphasizing methodologies. Third, this book draws mainly on the experience in Francophone countries which is still poorly disseminated. This book focusses on process and actors. Thus, the subject matter is divided into five major parts: the history and major issues of EA from a sustainable development perspective (Chapters 1 to 3); the actors, i.e. the Project Proponent and consulting firms, the public, the decision maker and international actors (Chapters 4 to 7); methods and tools including public participation (Chapters 8 and 9); processes in practice through step by step processes in practice and case studies (Chapters 10 and 11); and, finally, recent and upcoming developments in EA, including elements of strategic environmental assessment (Chapters 12 and 13). An index facilitates searching for information. The reader is also invited to consult the book's website

  7. The European Union as a Comprehensive Police Actor

    Directory of Open Access Journals (Sweden)

    Stephen Anthony Rozée

    2011-12-01

    Full Text Available The European Union (EU has responded to changing security threats by seeking to increase cooperation between the law enforcement agencies of the Member States, granting further powers to Europol and other intelligence-sharing institutions, and by undertaking police missions beyond EU borders. The literature relating to EU policing is generally focused on the ‘internal’ and ‘external’ dimensions, or on specific aspects of police activity. This tendency to concentrate on narrow or isolated areas of policing has led to a significant gap regarding the broader analysis of the EU as a comprehensive police actor. Important questions about the nature of EU policing as a whole, as well as the contribution of policing activities to the EU’s security agenda, remain unexplored in the literature. This article aims to define what is meant by ‘comprehensive policing’ and to indentify criteria by which the comprehensiveness of EU-level policing may be measured. In addition to this, an integrated actorness/police comprehensiveness framework will be presented as a tool for assessing the EU as a comprehensive police actor.

  8. Searching for realism, structure and agency in Actor Network Theory.

    Science.gov (United States)

    Elder-Vass, Dave

    2008-09-01

    Superficially, Actor Network Theory (ANT) and critical realism (CR) are radically opposed research traditions. Written from a realist perspective, this paper asks whether there might be a basis for finding common ground between these two traditions. It looks in turn at the questions of realism, structure, and agency, analysing the differences between the two perspectives and seeking to identify what each might learn from the other. Overall, the paper argues that there is a great deal that realists can learn from actor network theory; yet ANT remains stunted by its lack of a depth ontology. It fails to recognize the significance of mechanisms, and of their dependence on emergence, and thus lacks both dimensions of the depth that is characteristic of critical realism's ontology. This prevents ANT from recognizing the role and powers of social structure; but on the other hand, realists would do well to heed ANT's call for us to trace the connections through which structures are constantly made and remade. A lack of ontological depth also underpins ANT's practice of treating human and non-human actors symmetrically, yet this remains a valuable provocation to sociologists who neglect non-human entities entirely.

  9. The Psychological Self as Actor, Agent, and Author.

    Science.gov (United States)

    McAdams, Dan P

    2013-05-01

    The psychological self may be construed as a reflexive arrangement of the subjective "I" and the constructed "Me," evolving and expanding over the human life course. The psychological self begins life as a social actor, construed in terms of performance traits and social roles. By the end of childhood, the self has become a motivated agent, too, as personal goals, motives, values, and envisioned projects for the future become central features of how the I conceives of the Me. A third layer of selfhood begins to form in the adolescent and emerging adulthood years, when the self as autobiographical author aims to construct a story of the Me, to provide adult life with broad purpose and a dynamic sense of temporal continuity. An integrative theory that envisions the psychological self as a developing I-Me configuration of actor, agent, and author helps to synthesize a wide range of conceptions and findings on the self from social, personality, cognitive, cultural, and developmental psychology and from sociology and other social sciences. The actor-agent-author framework also sheds new light on studies of self-regulation, self-esteem, self-continuity, and the relationship between self and culture. © The Author(s) 2013.

  10. Biomass markets. Growth strategy and challenges for French actors

    International Nuclear Information System (INIS)

    2015-01-01

    This study comprises three reports. The first one is an executive summary which focuses on the main aspects of the evolution of the activity in the biomass sector, and highlights factors of change and their strategic consequences. The second one proposes an overview of the situation of biomass French markets, analyses growth strategies adopted by actors of the biomass sector (development of new production capacities, international growth, development of strategies based on several energies, diversification of prospects, innovation and improvement of installation efficiency), and discusses the main strategic challenges on the medium term. The third report proposes a presentation of the context of French biomass markets (political, regulatory and energetic framework, energetic assessment and assessment of the waste-based sector, economic context, housing stock, and other contextual factors), a presentation of the biomass French market (data for 2005-2013, dynamics of three specific segments: solid biomass, renewable urban wastes, and biogas), and a description of the competitive landscape (economic structure, actors) and of the 15 main actors

  11. Innovation in the plural of the alpine cre-actors

    Directory of Open Access Journals (Sweden)

    Andréa Finger-Stich

    2009-06-01

    Full Text Available The capacity to innovate for a sustainable development of alpine territories cannot depend only on economic, legal and political conditions defined by the State at national and international levels. It depends also on local conditions that situate historically and geographically the actors in a continuity of social and ecological relationships. This approach highlights the collective – thus organisational – dimensions of the innovation process, including the imagination, the development, the implementation and even the diffusion of a new practice. Our point of view is that for contributing to the sustainable development of the Alps, innovations need to change the ecological, political, social and cultural relationships engaging the actors in these territories. This change affects as much the object territory as the subject actor of the territory. This is why innovating in the Alps means also innovating the Alps and the alpine actors (Cosalp, 2008. Based on a research about local people’s participation in the management of alpine communal forests, the article shows the importance of local interactions involving actors of diverse occupation, gender, age and origins1.La capacité d’innovation pour un développement durable des territoires alpins ne peut dépendre uniquement de conditions économiques, légales et politiques définies par les Etats aux échelles nationale et internationale. Elle dépend aussi de conditions locales, qui situent historiquement et géographiquement les acteurs dans une continuité de relations sociales et écologiques. Cette perspective accentue l’importance de la dimension collective, donc organisationnelle, du processus d’innovation, allant de l’imagination, puis au développement, à la réalisation – voire la diffusion – d’une nouvelle pratique. Le point de vue de cet article est qu’une innovation, pour contribuer au développement durable des Alpes, doit changer les relations

  13. Importance of Actors and Agency in Sustainability Transitions: A Systematic Exploration of the Literature

    Directory of Open Access Journals (Sweden)

    Lisa-Britt Fischer

    2016-05-01

    Full Text Available This article explores the role of actors and agency in the literature on sustainability transitions. We reviewed 386 journal articles on transition management and sustainability transitions listed in Scopus from 1995 to 2014. We investigate the thesis that actors have been neglected in this literature in favor of more abstract system concepts. Results show that this thesis cannot be confirmed on a general level. Rather, we find a variety of different approaches, depending on the systemic level, for clustering actors and agency as niche, regime, and landscape actors; the societal realm; different levels of governance; and intermediaries. We also differentiate between supporting and opposing actors. We find that actor roles in transitions are erratic, since their roles can change over the course of time, and that actors can belong to different categories. We conclude by providing recommendations for a comprehensive typology of actors in sustainability transitions.

    Nelson F. González

    2018-01-01

    Full Text Available Resumen: Los beneficios de la actividad física y el ejercicio en la salud de la mujer son indiscutibles, hecho que está respaldado con fuerte evidencia científica en más de veinticinco condiciones médicas, incluidas la enfermedad cardiovascular y la mortalidad prematura.La actividad física provee beneficios de forma multifactorial con efectos en el sistema inmune, hemostático, autonómico, metabólico y hormonal entre otros, que pueden ser aplicables en las diferentes etapas de la historia fisiológica de la mujer. Por ende se requiere un abordaje específico de cada una de esas etapas para dar provecho a todas las ganancias que trae consigo la práctica del ejercicio físico.Los beneficios de la actividad física y la prescripción de ejercicio individualizada siempre superan considerablemente los posibles riesgos a los que se exponen por su práctica. A la hora de la prescripción del ejercicio es importante tener en cuenta características propias de la mujer, como composición corporal y rasgos endocrinológicos ya que representan diferencias en la respuesta fisiológica al ejercicio agudo y a entrenamientos prolongados. Adicionalmente, dentro de la evaluación médica es importante hacer una búsqueda activa de los riesgos cardiovascular, osteoarticular y metabólico.A pesar de los beneficios demostrados, los indicadores de inactividad física y sus consecuencias siguen siendo alarmantes en las mujeres. Estrategias que promuevan la actividad física en las mujeres y que permitan eliminar las barreras de acceso, además de nuevos métodos para cuantificar de manera indicada los niveles de actividad física, se convierten en un desafío para los profesionales de la salud y los planificadores de políticas de salud pública. Abstract: The benefits of physical activity and exercise on health are indisputable for women. There is scientific evidence of the benefits in more than 25 medical conditions, including cardiovascular disease and

    2015-06-01

    Full Text Available Os produtos das atividades de mineração têm grande relevância econômica no Estado de Minas Gerais, Brasil. No entanto, seus inúmeros danos à biota, incluindo a fauna edáfica, resultam na necessidade de recuperação e biomonitoramento dessas áreas e do seu entorno. Considerando a importância ecológica e o potencial bioindicador das minhocas, o objetivo deste estudo foi avaliar a toxicidade de arsênio presente em solos do entorno de minerações de ouro, nas bacias dos rios Doce e São Francisco, a oligoquetas da espécie Eisenia andrei Bouché. Amostras de solos dessas áreas foram caracterizadas em relação às suas propriedades físicas e químicas, incluindo os metais Fe, Al, Cu, Ni, Zn e Mn e do metaloide As; com elas, foram conduzidos bioensaios, que avaliaram a sobrevivência, reprodução e variação da biomassa dos organismos. Também foram realizados testes de sensibilidade dessa espécie ao As adicionado a solo artificial tropical e em solo natural. Houve evidente efeito tóxico sobre a reprodução dessa espécie, que esteve altamente correlacionado com as concentrações de As nas amostras (r = -0,80. Amostras de solos naturais de locais avaliados nas duas áreas apresentaram concentrações de As acima do limite estipulado pela Resolução Conama nº 420 de 2009, chegando a 2.388,2 mg kg-1. A CL50 do As em solo artificial tropical (207,4 mg kg-1 foi seis vezes menor que a do solo natural (1.248,1 mg kg-1. A menor biodisponibilidade do As nos solos naturais foi atribuída a sua associação com o minério de Fe presente nas amostras. Concluiu-se que os solos do entorno de áreas de mineração causaram toxicidade crônica a E. andrei, em termos de sua reprodução, o que demonstrou o potencial de danos dessas atividades sobre a fauna edáfica dessas áreas. O estudo também forneceu informações ecotoxicológicas que podem ser úteis em avaliações de risco ambiental em solos tropicais.

    Melloni Rogério

    2003-01-01

    Full Text Available Apesar de a mineração de bauxita causar grandes alterações nas características do solo, com efeitos negativos nas micorrizas arbusculares, os efeitos da reabilitação de áreas mineradas sobre os fungos micorrízicos arbusculares (MA e sua simbiose são pouco conhecidos. O objetivo deste trabalho foi avaliar a ocorrência, diversidade e eficiência dos fungos MA, em áreas de mineração de bauxita, com diferentes tipos de vegetação e idades de reabilitação. Amostras de solo da rizosfera foram coletadas para analisar o micélio fúngico extrarradicular, o número de esporos, a riqueza e diversidade de fungos MA e para avaliar a colonização micorrízica e eficiência simbiótica de populações fúngicas. A mineração afetou negativamente os fungos MA, sendo a recuperação destes mais relacionada com o tipo de vegetação do que com o tempo de reabilitação da área. Foram encontradas as espécies: Gigaspora margarita, Gigaspora sp., Paraglomus occultum, Glomus sp., Entrophospora colombiana e Acaulospora scrobiculata. A ocorrência desses fungos foi favorecida pela presença de gramíneas ede bracatinga. Embora Eucalyptus saligna não seja um bom hospedeiro para os fungos MA, quando associado a sub-bosque bem desenvolvido e diverso, contribuiu para a recuperação dos fungos. As populações fúngicas isoladas de áreas com braquiária e feijão-guandu ou de bracatinga com capim-gordura apresentaram elevada eficiência para o feijoeiro, mostrando que é possível recuperar a função deste grupo de microrganismos utilizando diferentes tipos de vegetação.

  18. The role of social actors in times of crisis / El papel de los actores sociales en tiempos de crisis

    Directory of Open Access Journals (Sweden)

    Iván Medina Iborra

    2013-10-01

    Full Text Available The aim of this article is to analyze the performance of the two main trade unions (UGT and CCOO and the employers’ association CEOE during the economic crisis. The analysis focuses on their position on major reforms, on their ideological differences over various public policies, as well as on their ability to negotiate collective bargaining agreements. We depart from the command of the Spanish Constitution of 1978, which in its seventh article gives trade unions and business associations a prominent role in representing economic interests, to suggest that social actors would be likely to reduce their chances of veto in times of economic crisis given the exceptional situation. However, the article confirms a gap in the approaches of social actors and the few options for a strong social dialogue. This leads to a greater distance between the social actors and the public opinion, as evidenced by the results derived from the survey on ‘Culture and Political Representation in Spain’.

  14. A Low-cost System for Generating Near-realistic Virtual Actors

    Afifi, Mahmoud; Hussain, Khaled F.; Ibrahim, Hosny M.; Omar, Nagwa M.

    2015-06-01

    Generating virtual actors is one of the most challenging fields in computer graphics. The reconstruction of a realistic virtual actor has been paid attention by the academic research and the film industry to generate human-like virtual actors. Many movies were acted by human-like virtual actors, where the audience cannot distinguish between real and virtual actors. The synthesis of realistic virtual actors is considered a complex process. Many techniques are used to generate a realistic virtual actor; however they usually require expensive hardware equipment. In this paper, a low-cost system that generates near-realistic virtual actors is presented. The facial features of the real actor are blended with a virtual head that is attached to the actor's body. Comparing with other techniques that generate virtual actors, the proposed system is considered a low-cost system that requires only one camera that records the scene without using any expensive hardware equipment. The results of our system show that the system generates good near-realistic virtual actors that can be used on many applications.

    The Millennium Development Goals have ended and the Sustainable Development Goals have begun, marking a shift in the global health landscape. The frame of reference has changed from a focus on 8 development priorities to an expansive set of 17 interrelated goals intended to improve the well-being of all people. In this time of change, several groups, including the Lancet Commission on Global Surgery, have brought a critical problem to the fore: 5 billion people lack access to safe, affordable surgical and anaesthesia care when needed. The magnitude of this problem and the world's new focus on strengthening health systems mandate reimagined roles for and renewed commitments from high income country actors in global surgery. To discuss the way forward, on 6 May 2015, the Commission held its North American launch event in Boston, Massachusetts. Panels of experts outlined the current state of knowledge and agreed on the roles of surgical colleges and academic medical centres; trainees and training programmes; academia; global health funders; the biomedical devices industry, and news media and advocacy organisations in building sustainable, resilient surgical systems. This paper summarises these discussions and serves as a consensus statement providing practical advice to these groups. It traces a common policy agenda between major actors and provides a roadmap for maximising benefit to surgical patients worldwide. To close the access gap by 2030, individuals and organisations must work collectively, interprofessionally and globally. High income country actors must abandon colonial narratives and work alongside low and middle income country partners to build the surgical systems of the future. PMID:28588908

Asimismo, un gran número de micobacterias no tuberculosas, especialmente M. avium, M. intracellulare y M. chelonae, causan infecciones oportunistas en pacientes con SIDA. Muchos terpenos poseen actividad biológica y se emplean en el tratamiento de diversas enfermedades, razón que los hace fuente de moléculas promisorias. Objetivo: El objetivo del presente estudio fue determinar la actividad antimicobacteriana de 16 terpenos contra M. tuberculosis H37Rv y un aislamiento clínico de M. chelonae. Materiales y métodos: Se obtuvo la concentración mínima inhibitoria (CMI de los mismos y se realizaron curvas de letalidad para establecer actividad bactericida, empleando una técnica de macrodilución en caldo estandarizada para este tipo de compuestos volátiles. Resultados: Los terpenos con menor valor de CMI fueron timol y carvacrol, con concentraciones de 125-250 μg/mL, y actividad bactericida contra los dos microorganismos. Geraniol, mirceno, ρ-cimeno, alfa-pineno, presentaron valores de CMI entre 250 y 500 μg/mL. Conclusiones: Algunos terpenos han presentado actividad importante contra microorganismos del género Mycobacterium, sin embargo los valores de CMI obtenidos no explican el efecto antimicrobiano presentado por el aceite completo, se requiere evaluar las interacciones de sinergismo y/o antagonismo entre los terpenos para determinar los componentes responsables de la acción farmacológica.

  15. The population-development tangle. Aspects and actors.

    Since the 1974 Population Conference, the population field has become of interest to members of the fundamentalist right wing, feminists, and environmentalists. Therefore, it is necessary to understand the areas of agreement and disagreement among each set of actors as well as how they define the issues. Currently, development discourse is characterized by considerations of: 1) economic growth, 2) the provision of livelihoods, 3) the provision of basic needs, 4) ecological sustainability and renewability, and 5) political participation. The actors who define the terms of this discourse include: 1) corporate interests, which concentrate on economic growth; 2) international and national agencies, which place primary importance on economic growth and some importance on basic needs and ecological sustainability; 3) popular organizations and social movements, which concentrate on livelihoods, basic needs, and political participation; and 4) environmentalists, who focus on ecological sustainability, economic growth, and (occasionally) political participation. The field of population, on the other hand, is dominated by traditional populationists, whose primary focus is economic growth; developmentalists; the fundamentalist right, who are most concerned with family and control over reproduction; environmentalists; and the women's movement, which is most concerned with reproductive rights and reproductive health. When the perspective of poor women is considered, it can be seen that economic growth and ecological sustainability must support the securing of livelihoods, basic needs, political participation, and reproductive rights, and that reproductive health programs must be part of an overall health agenda.

  16. Understanding Health Information Seeking from an Actor-Centric Perspective

    Full Text Available This paper presents a conceptual approach for discussing health information seeking among poor households in Africa and Asia. This approach is part of a larger research endeavor aimed at understanding how health systems are adapting; with possibilities and constraints emerging. These health systems can be found in a context of the changing relationships between states, markets and civil society in low and middle income countries. The paper starts from an understanding of the health sector as a “health knowledge economy”, organized to provide people with access to knowledge and advice. The use of the term “health knowledge economy” draws attention to the ways the health sector is part of a broader knowledge economy changing the way individuals and households obtain and use specialist information. The paper integrates an actor centric approach with the theory of planned behavior. It seeks to identify the actors engaged in the health knowledge economy as a precursor to longer term studies on the uptake of innovations integrating health services with mobile phones, commonly designated as mHealth, contributing to an understanding of the potential vulnerabilities of poor people, and highlighting possible dangers if providers of health information and advice are strongly influenced by interest groups.

    Full Text Available Building A creative Barcelona: new actors, new strategies.Barcelona is under the international spotlight. The city that triumphed with the organisation of the Olympic Games in 1992 now wants to become a 21st Century creative city. In order to achieve this goal, the city must establish conditions that facilitate the emergence of a shared discourse around its ability to become an attractive city for creative talent and for businesses. The recognition of the historical-economic heritage, as a starting point for the creative city, along with the driving role played by culture in the generation of a exclusive and distinctive experience, turnBarcelona into a unique city. However, this is not sufficient. The participation and involvement of all the actors in a shared strategy pose significant challenges to Barcelona, as does the need to minimise the negative effects that inevitably accompany success. Companies, institutions and citizens constitute the city’s best assets: they must work in partnership and take advantage of the synergies generated amongst them. Consensus and participation are more than mere utopias in Barcelona: they have become requirements for the city of tomorrow. Moreover, leadership in Barcelona is largely left to public initiative: the emergence of linkages across the needs of the various creative sectors, based on public intervention mechanisms is the best way to ensure success.

    Full Text Available The 1999 Tampere Summit marked the start of the development of the external dimension of the European Union’s policy of Justice and Home Affairs (JHA. This external dimension has been reflected in the inclusion of JHA in agreements with third countries, and particularly with Mediterranean countries. Furthermore, the European NeighbourhoodPolicy (ENP, in addition to bilateral and multilateral programmes, confirmed the transformation of the JHA policy into one of the EU’s foreign policy objectives. In the light of this evolution, this article examines Spain’s role in the development of the Mediterraneandimension of the JHA policy: firstly, it covers the stance of José Luis Rodríguez Zapatero’s government toward the JHA policy and its external dimension; secondly, it explores the new parameters of governance in the area of security and the Spanish case through three main factors: the neighbours, spaces and actors that define this governance. Lastly, and within a context of a multiplicity of governance actors on security, it focuses on the Canary Islands,which have acquired a central importance with respect to the management of borders and the policy of development for Africa. The analysis of this period helps to explain the new security perceptions that define Spain’s policy in the Mediterranean.

    Full Text Available Dr. Gil questions the role played by Mexican university academics in the transformation of higher education during the nineties. After outlining the general context of change and its importance, the author proposes avoiding the false dichotomy between restoring the past or installing, without reflective mediation, a schematic future. He suggests taking into consideration the current national academic body composed of several generations of scholars. Three phases are established in terms of the modification of academic activities during the last decades of the twentieth century, and the changes in the level of higher education are considered. Dr. Gil asks if the academics have been actors, subjects, spectators or hostages-both in regard to regulations governing their activity and in the modifications of university processes and structure. The essay ends by proposing a general agenda for research in the field of university studies, and emphasizes two problems: the need for a detailed description of the type and depth of changes, and the definition of the academic as a central actor in institutional life.

    Full Text Available The aim of this article is to portray the main shifts which have been taking place in Colombian drug scene since the 70’s up to the present especially in relation to actors of this business and form of their activity. At first the development of Colombian drug trade till the 80’s when two big cartels centered in Medellín and Cali arose will be briefly outlined. These cartels were able to control a great part of domestic drug trade and due to their enormous power represented serious threat to Colombian state. Thus the cartels declared open warfare with the state in the 80’s. After the cartels’ elimination in the middle of 90’s new actors represented by small drug organizations arose in Colombian drug scene. These small groups were dependent upon cooperation with foreign partners, especially with Mexican cartels. Ever more important role in drug business is played by Colombian left-wing guerilla groups which will be described in the next part of the article. The problem of right-wing paramilitary groups and their participation in Colombian drug trade will be mentioned as well.

En este artículo se establecen una serie de consideraciones tendientes a cambiar estructuralmente las relaciones pedagógicas en el aula, en el contexto de las ciencias sociales en la educación superior pública, de tal manera que se desencadene y sostenga un proceso motivacional entre los estudiantes y el profesor, hacia la actividad cognoscitiva y la asimilación consciente del conocimiento, utilizando como referente las teorías motivacionales en las organizaciones.

  8. Action adaptation during natural unfolding social scenes influences action recognition and inferences made about actor beliefs.

    When observing another individual's actions, we can both recognize their actions and infer their beliefs concerning the physical and social environment. The extent to which visual adaptation influences action recognition and conceptually later stages of processing involved in deriving the belief state of the actor remains unknown. To explore this we used virtual reality (life-size photorealistic actors presented in stereoscopic three dimensions) to see how visual adaptation influences the perception of individuals in naturally unfolding social scenes at increasingly higher levels of action understanding. We presented scenes in which one actor picked up boxes (of varying number and weight), after which a second actor picked up a single box. Adaptation to the first actor's behavior systematically changed perception of the second actor. Aftereffects increased with the duration of the first actor's behavior, declined exponentially over time, and were independent of view direction. Inferences about the second actor's expectation of box weight were also distorted by adaptation to the first actor. Distortions in action recognition and actor expectations did not, however, extend across different actions, indicating that adaptation is not acting at an action-independent abstract level but rather at an action-dependent level. We conclude that although adaptation influences more complex inferences about belief states of individuals, this is likely to be a result of adaptation at an earlier action recognition stage rather than adaptation operating at a higher, more abstract level in mentalizing or simulation systems.

    recursos minerales en los parajes más recónditos del país. La llegada de estas grandes empresas no solo significó un enorme crecimiento macroeconómico sino también una cuantiosa inyección de capital y un cambio en el acceso de los recursos naturales. Estos cambios causaron diferentes protestas en las comunidades campesinas ubicadas en las áreas de influencia minera que dan pie a la creación de nuevas perspectivas de cómo lograr un desarrollo local. Una de las maneras de estudiar las interacciones entre estos dos actores —la mina y las comunidades— es mediante el uso del análisis de discurso y narrativas.De este modo, este artículo tiene como objetivo hallar las conexiones entre IFD, acceso a los recursos y desarrollo local en nueve comunidades en la cuenca del río Ayash y la multinacional Compañía Minera Antamina (CMA. En este sentido, se utilizaron métodos cualitativos para describir y analizar los efectos directos e indirectos en la población y en su acceso a los recursos. También se analizará cómo la ausencia del Estado puede dar cabida a un uso inadecuado de la Responsabilidad Social Corporativa (RSC y, en consecuencia, motivar a las comunidades a reclamar compensaciones por los daños ambientales. Siguiendo esta línea, se utilizará el Análisis de Discurso para esquematizar estas protestas en forma de narrativas de desarrollo y establecer nuevas consideraciones para futuros y actuales proyectos de IFD en minería.

    In the German movie "Vincent will Meer" a healthy actor portrays a man with Tourette's syndrome. Objective. The aim of this study was to investigate whether the performance of tics is convincing and whether this judgment depends on whether he/she suffers from tics or not. While the movie was broadcasted in German cinemas, we put an online survey (including 28 questions on different aspects related to the observation, performance, and authenticity of tics) on the web pages of the German self-help group. 276/296 surveys submitted could be used for further analyses. 95.7% of all participants felt that the performance of tics was convincing. However, people with tics (n = 26) were less convinced compared to those who had never met a person with tics (n = 110) (P = 0.020). Our results further support the hypothesis that tics are not "abnormal" but "physiological" movements that are only misplaced both in time and context.

    Cities concentrate populations, consumptions, levers of actions, and are places of various experiments for energy transition. This book aims at giving an overview of possible scenarios of development of renewable energies in urban context. It is based on interviews of actors of the energy, building and urban planning sectors by researchers in town planning, management, technology, political and economic sciences. The authors examine what would occur if large companies would manage entire quarters, if local authorities would supervise production and supply, if the State would take control of all fields of action again, or if consumer cooperatives would exchange energy and pool productions. In its different chapters, the book presents four scenarios of energy coordination in urban context by 2040, discuss energy transition in urban spaces, discuss the perspectives of evolution towards more autonomous cities and quarters from an energetic point of view, and discuss business models and urban energetic innovations

    Full Text Available El 1 de enero del año 2006, entró a regir el impuesto especial o adicional a la renta operación de las empresas mineras, conocido como Royalty. Más allá de las diferentes formas en que fue técnicamente planteado, su discusión permitió observar algunas realidades anexas dignas de un análisis más detenido. La más relevante quizá haya sido el bajo apoyo ciudadano y político que concita la industria minera, a pesar de sus importantes e indiscutibles aportes económicos, el reconocimiento del cumplimiento de la ley y el pago de los impuestos que ella exige. En segundo lugar, mostró algunos mecanismos de nuestro sistema tributario general, especialmente notorios en sectores intensivos en el uso de capital, que permiten resultados complejos y difíciles de explicar a la ciudadanía, y de cuya existencia la industria minera no tenía responsabilidad alguna. La combinación de ambas situaciones, más la oposición ideológica e histórica a la minería, la puso en una frágil posición, que en buena medida explica la facilidad con que fue aprobado un tributo específico tan débilmente fundado. Sostenemos en este trabajo que en lugar del royalty, hubiese sido deseable implementar un plan perfeccionador general de la institucionalidad tributaria, que terminase con las opciones o alternativas tributarias (principalmente en depreciación, la desigualdad de trato ofrecidos a algunos contribuyentes (principalmente entre chilenos y extranjeros y aumentase el bajísimo monto actual de las patentes mineras. Creemos que ellas ofrecían interesantes posibilidades que beneficiarían tanto a la institucionalidad minera como al sistema tributario general. Desgraciadamente, la ley del royalty, en vez de asumir esos puntos, crea una serie de excepciones, beneficios y situaciones especiales, de las cuales muchas buscaron atenuar los efectos negativos del impuesto, pero van en la dirección opuesta a lo propiciado por los autores, en cuanto a simplificar y

    “REDD+” is a mechanism created under the United Nations Framework Convention on Climate Change (UNFCCC) for Reducing {carbon} Emissions from Deforestation and Degradation and forest enhancement. In addition, REDD+ “safeguards” are intended to protect non-carbon forest values. While REDD+ countries are formally requested to provide information on safeguards, there is as yet no agreement on the relative priority of carbon versus non-carbon values, and the appropriate level of safeguard standardization. This, we argue, has allowed REDD+ to function as a “boundary object” spanning disparate priorities. Meanwhile, the contestation of these priorities has been displaced from intergovernmental processes to the various organizations involved in operationalizing REDD+ activities. This article applies a set of organizational, substantive and conceptual typologies to compare differences in the balance of actors, interests and ideas across these organizations. It finds that multi-lateral funding programs have drawn heavily on existing safeguards for international aid, while private certification schemes have specialized in different niche priorities at the project level. In regards to the substance of safeguard requirements, the involvement of donors and investors appears correlated with a stronger emphasis on carbon and risk mitigation while greater NGO involvement and the decoupling of safeguards design from REDD+ funding appear correlated with greater emphasis on social rights and benefits. These findings have several critical implications for future REDD+ activities. Firstly, the choice of organizations involved in defining, funding and verifying safeguard activities, and the balance of actors in their governing structures, are likely to influence the relative emphasis on non-carbon values. Secondly, a diversity of approaches to disbursing REDD+ incentives may be necessary to maintain widespread support for REDD+. Thirdly, it remains to be seen whether REDD

    Full Text Available Este artículo presenta una descripción del funcionamiento de la disciplina escolar en una institución educativa de secundaria en Colombia. Tiene como objetivo explicar el origen del conflicto disciplinario, las situaciones que lo generan, la forma como la institución trata de lograr y mantener la disciplina, las explicaciones que cada uno de los actores da a las situaciones conflictivas y la manera como son vividas por ellos. El diseño metodológico de la investigación combinó una encuesta, entrevistas y el análisis de documentos de la institución educativa. El análisis de los datos se hace a la luz de planteamientos sociológicos que reconocen la enorme importancia que ejercen las estructuras sociales sobre la forma de pensar y actuar de los individuos, pero también resaltan la gran capacidad de los actores sociales para amoldarse a dichas estructuras y a través de sus ideas y acciones darle una dinámica propia al tipo de relaciones que establecen entre individuos en sus entornos de vida más inmediatos. Se pudo concluir que sobre la disciplina escolar no hay unidad de criterio entre los docentes, los directivos y los estudiantes, ni en su definición, ni en su importancia, ni en los medios para conseguirla; dichas diferencias producen tensiones y desacuerdos entre los miembros de la comunidad educativa.

    In Turkey, the discussions in the modern sense about disaster management begun after the 1992 Erzincan and the 1995 Dinar earthquakes, faulting in terms of features and effects. These earthquakes are "Urban Earthquakes'' with effects and faulting charectristics, and have led to radical changes in terms of disaster and disaster management. Disaster Management, to become a science in the world, but with the 1999 Izmit and Duzce earthquakes in Turkey has begun to take seriously on the agenda. Firstly, such as Civil Defense and Red Crescent organizations, by transforming its own, have entered into a new organizing effort. By these earthquakes, NGO's have contributed the search-rescue efforts in the field and to the process of normalization of life. Because "the authority and responsibilities" of NGO's could not be determined, and could not be in planning and scenario studies, we faced the problems. Thus, to the citizens of our country-specific "voluntary" has not benefited enough from the property. The most important development in disaster management in 2009, the Disaster and Emergency Management Presidency (AFAD) has been the establishment. However, in terms of coordination and accreditation to the target point has been reached yet. Another important issue in disaster management (need to be addressed along with disaster actors) is the role of women in disasters. After the Golcuk Earthquake, successful field works of women and women's victimization has attracted attention in two different directions. Gender-sensitive policies should be noted by the all disaster actors due to the importance of the mitigation, and these policies should take place in laws, regulations and planning.

    Full Text Available Adequate and accessible expert-based forest information has become increasingly in demand for effective decisions and informed policies in the forest and forest-related sectors in Europe. Such accessibility requires a collaborative environment and constant information exchange between various actors at different levels and across sectors. However, information exchange in complex policy environments is challenging, and is often constrained by various institutional, actor-oriented, and technical factors. In forest policy research, no study has yet attempted to simultaneously account for these multiple factors influencing expert-based forest information exchange. By employing a policy analysis from an actor-centred institutionalist perspective, this paper aims to provide an overview of the most salient institutional and actor-oriented factors that are perceived as constraining forest information exchange at the national level across European countries. We employ an exploratory research approach, and utilise both qualitative and quantitative methods to analyse our data. The data was collected through a semi-structured survey targeted at forest and forest-related composite actors in 21 European countries. The results revealed that expert-based forest information exchange is constrained by a number of compound and closely interlinked institutional and actor-oriented factors, reflecting the complex interplay of institutions and actors at the national level. The most salient institutional factors that stand out include restrictive or ambiguous data protection policies, inter-organisational information arrangements, different organisational cultures, and a lack of incentives. Forest information exchange becomes even more complex when actors are confronted with actor-oriented factors such as issues of distrust, diverging preferences and perceptions, intellectual property rights, and technical capabilities. We conclude that expert-based forest information

    The actor-dimension of the Activitiy-Resource-Actor (ARA)-model has not gained the same attention among Industrial Marketing and Purchasing (IMP) scholars as the resource and activity dimensions. However, the issue of what an actor actually is, in the sense of its interactive constitution, is important from an industrial marketing and purchasing perspective that emphasizes the interactive character of the business landscape. This is adressed in this paper. As a concequence of their interactiv...

    Full Text Available En fútbol, el patrón de actividad de jugadores adultos, tanto masculinos como femeninos, ha sido ampliamente estudiado, pero son escasos los estudios que han centrado su atención en el análisis de los desplazamientos de los jugadores de categorías infantiles. Un mayor conocimiento de las demandas de este deporte en las etapas iniciales permitiría la confección de programas de entrenamiento más acordes con las características de los chicos de estas edades. El objetivo del presente estudio fue cuantificar de los desplazamientos en jugadores de fútbol de categoría infantil (12,2 ± 0,6 años; 156 ± 0,8 cm y 51 ± 5,2 kg que pertenecían a la selección de la ciudad autónoma de Melilla, mediante la aplicación de dispositivos basados en tecnología GPS. Los resultados obtenidos certifican que el fútbol infantil es una especialidad deportiva intermitente en la que se intercalan actividades de alta intensidad con situaciones del juego que permiten que el jugador recupere estando parado, andando o con una velocidad de carrera muy baja. La tasa trabajo-descanso fue de 1:3,5 y la distancia media recorrida por minuto fue aproximadamente de 100 m. Esta distancia varía disminuyendo de forma lineal conforme transcurre el partido, existiendo diferencias significativas entre el inicio y el final del juego, lo que indicaría la aparición de la fatiga. Los esfuerzos de alta intensidad que se realizan implican el 6,1% del tiempo de juego y el 16,3 % de la distancia recorrida, efectuando un sprint máximo de entre 10 y 15 m de media, cada 141 segundos. La aplicación de tareas que reproduzcan la intensidad del juego durante cortos periodos de tiempo (no superiores a 10 minutos aseguraría una elevada intensidad de trabajo durante los entrenamientos.

  5. Confidence, Actors' Beliefs and Transparency: the Case of ANDRA

    International Nuclear Information System (INIS)

    Buclet, Nicolas; Bouzidi, Youcef

    2003-01-01

    Considering the predominant position of nuclear power in France, one could think that nuclear in France has always benefited from a high consensus within the French opinion. The emerging of nuclear and its development through years in France, might seem to have taken place in a rather singular climate of good social acceptability, if compared with other countries. Yet, now that the question has to be raised concerning the management of long-life radioactive waste, things are complicated. A strong contest accompanies each choice of a site that could be dedicated to stocking those very sensitive wastes. Actually, only one site has been found and accepted by local political authorities. A laboratory has been created by ANDRA, with the scope to study the opportunity to stock long-life radioactive waste. The decision should take place in 2006 and, since many years, is at the origin of a strong controversy between actors in favour or against the project. How to explain that? Why in a country where everything has been done for the nuclear development, is it so difficult to find a place to manage the residues of such an activity? It is even amazing to see that, on this specific topic, controversy is even stronger in France than in Sweden, although the Swedish opinion is by far less nuclear-friendly than the French one. The present paper focuses on one aspect of the strategy followed by ANDRA in order to achieve its mission: the essential aspect of the social acceptability of its activities. The comprehension of the difficulties met by ANDRA is not possible without taking into account the history of French nuclear and the catastrophic lack of democracy that characterised it. Among the results from an inquiry done by CREIDD for ANDRA in 2002, it indeed emerged that ANDRA was most of all perceived as an entity belonging to a global 'nuclear sphere'. Although rather young, ANDRA therefore has to carry with it the 'weigh of history' of the whole 'sphere', and its social

  6. Recollection and unitization in associating actors with extrinsic and intrinsic motions.

    Four experiments provide evidence for a distinction between 2 different kinds of motion representations. Extrinsic motions involve the path of an object with respect to an external frame of reference. Intrinsic motions involve the relative motions of the parts of an object. This research suggests that intrinsic motions are represented conjointly with information about the identities of the actors who perform them, whereas extrinsic motions are represented separately from identity information. Experiment 1 demonstrated that participants remembered which actor had performed a particular intrinsic motion better than they remembered which actor had performed a particular extrinsic motion. Experiment 2 replicated this effect with incidental encoding of actor information, suggesting that encoding intrinsic motions leads one to automatically encode identity information. The results of Experiments 3 and 4 were fit by Yonelinas's (1999) source-memory model to quantify the contributions of familiarity and recollection to memory for the actors who carried out the intrinsic and extrinsic motions. Successful performance with extrinsic motion items in Experiment 3 required participants to remember in which scene contexts an actor had appeared, whereas successful performance in Experiment 4 required participants to remember the exact path taken by an actor in each scene. In both experiments, discrimination of old and new combinations of actors and extrinsic motions relied strongly on recollection, suggesting independent but associated representations of actors and extrinsic motions. In contrast, participants discriminated old and new combinations of actors and intrinsic motions primarily on the basis of familiarity, suggesting unitized representations of actors and intrinsic motions.

    Full Text Available Los patrimonios procedentes de las actividades en declive como la minería pasan por una etapa de atención, tras décadas de abandono, como recurso para una nueva modalidad de turismo cultural. De ello hay numerosas experiencias, fundamentalmente, en los países de cultura industrial (Reino Unido, Alemania, Estados Unidos, etc., con efectos económicos apreciables sobre el ámbito territorial en el que se ubican. España cuenta ya con algunos ejemplos válidos para fundamentar la hipótesis de que la conservación y adaptación al uso turístico de este patrimonio ha dado resultados aceptables en determinadas regiones del país (Asturias, Andalucía, Cataluña, etc.. Al margen de los éxitos alcanzados, se corre el riesgo de sacar la conclusión de que todo el patrimonio minero es capaz por sí mismo de impulsar la creación de riqueza y empleo en el medio rural, sin embargo, la realidad es otra, a pesar de haber iniciativas, recursos y muchas administraciones públicas involucradas. Precisamente, la gran variedad de actores en juego con intereses dispares junto a las dificultades para su despegue constituyen estrangulamientos que condicionan que el proceso anterior se inicie o culmine. Tal será la hipótesis de partida de esta contribución.

  9. Defining and Theorizing Terrorism: A Global Actor-Centered Approach

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Arriving at a consensual definition of the phenomenon of terrorism has been a particularly difficult undertaking. Some definitions are either too specific or too vague, concentrating on some essential “terrorist” aspect of the actions, strategies, or types of non-state organizations that engage in terrorism. In this paper I draw on global approaches from international relations and world systems theories to propose a definition of terrorism that skirts these issues by concentrating on terrorist actors rather than terrorist behavior. I argue that this approach has several advantages, including the dissolution of several empirical and analytical problems produced by more essentialist definitions, and the location of terrorism within a two dimensional continuum of collective-violence phenomena in the international system which discloses important theoretical insights. I proceed to examine the characteristics of terrorism by comparing it with other forms of violence in the international system. I propose that terrorism may be part of the cycles and trends of unrest in the world system, responding to the same broad families of global dynamics as other forms of system-level conflict.

The aim of this study was to investigate whether the performance of tics is convincing and whether this judgment depends on whether he/she suffers from tics or not. Methods. While the movie was broadcasted in German cinemas, we put an online survey (including 28 questions on different aspects related to the observation, performance, and authenticity of tics on the web pages of the German self-help group. 276/296 surveys submitted could be used for further analyses. Results. 95.7% of all participants felt that the performance of tics was convincing. However, people with tics (n=26 were less convinced compared to those who had never met a person with tics (n=110 (P=0.020. Conclusions. Our results further support the hypothesis that tics are not “abnormal” but “physiological” movements that are only misplaced both in time and context.

    Full Text Available This article aims to reconstruct the history of civil society in Quebec (Canada to relate it with nationalism, the rise of the welfare state, trade unions, Catholic Church and civil society, the dynamic forces of society. Through in-depth interviews with key leaders, exploration of institutional archives and specific literature, we work with a particular case that, when compared to Catalonia, will allow us to evaluate the importance of civil society within nationalism. This actor is not usually considered as the central subject of researches and rarely token into account, unlike political parties, their leaders or intellectuals. Currently, in a context of crisis of the state and political parties, it has begun to be considered that civil society can be a key factor for its ability to produce alliances between sectors, build hegemony and dialogue directly with the population. The study is divided into four parts: 1 the development of the theoretical framework along with the construction of the object of study and the hypotheses; 2 an analysis about the importance of the involvement of civil society in the construction of the nationalist movement in Quebec; 3 a comparison with the Catalan case; and, 4 finally some conclusions.

    To analyse the role of Mexico's mental health system governance in the development of mental health policies and programmes, from the perspective of its own actors. A map was developed for identifying the actors in Mexico's mental health system. A guide was designed for in-depth interviews, which were recorded and arranged in categories for their analysis. The Atlas-ti v.7 software was used for the organisation of qualitative data and Policy Maker v.4 was used to determine the position and influence of actors within the health system. The actors were identified according to their level of influence in mental health policies: high, medium and low. Actors with a high level of influence participate in national policies, actors with medium influence are involved in regional or local policies and the participation of actors with a low level of influence is considered marginal. This study facilitated understanding of governance in mental health. The level of influence of the actors directly affects the scope of governance indicators. Relevant data were obtained to improve policies in mental health care. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

    2014-01-01

    Full Text Available Wireless Sensor and Actor Networks (WSANs refer to a group of sensors and actors linked by wireless medium to probe environment and perform specific actions. Such certain actions should always be taken before a deadline when an event of interest is detected. In order to provide such services, the whole monitor area is divided into several virtual areas and nodes in the same area form a cluster. Clustering of the WSANs is often pursued to give that each actor acts as a cluster-head. The number of actors is related to the size and the deployment of WSANs cluster. In this paper, we find a method to determine the accurate number of actors which enables them to receive data and take actions in an imposed time-delay. The k-MinTE and the k-MaxTE clustering algorithm are proposed to form the minimum and maximum size of cluster, respectively. In those clustering algorithms, actors are deployed in such a way that sensors could route data to actors within k hops. Then, clusters are arranged by the regular hexagon. At last, we evaluate the placement of actors and results show that our approach is effective.

    Literacy testing objects as co-actors in framing bilingual children´s literacy development Based on Latour´s theoretical perspective that human beings delegate roles and responsibility to artifacts, it becomes important to track and research the objects that circulate within and between “sites...... of human social interaction” (Latour, 2005). Latour argues that objects – e.g. a literacy testing instrument – play a central role through the meaning, human beings delegate to objects. In this way objects become co-actors in a network through the agency human actors delegate to them, and objects mediate...... categories and artifacts based on the local context. The second is termed “globalising connects” that brings local actors in line with bigger and remote networks. In order to understand the semiotic function of artifacts in a meaning making network an ethnographic oriented approach with a focus on actor...

    2018-03-01

    The Actor model of concurrent computation discretizes a problem into a series of independent units or actors that interact only through the exchange of messages. Without direct coupling between individual components, an Actor-based system is inherently concurrent and fault-tolerant. These traits lend themselves to so-called "Big Data" applications in which the volume of data to analyze requires a distributed multi-system design. For a practical demonstration of the Actor computational model, a system was developed to assist with the automated analysis of Nondestructive Evaluation (NDE) datasets using the open source Myriad Data Reduction Framework. A machine learning model trained to detect damage in two-dimensional slices of C-Scan data was deployed in a streaming data processing pipeline. To demonstrate the flexibility of the Actor model, the pipeline was deployed on a local system and re-deployed as a distributed system without recompiling, reconfiguring, or restarting the running application.

    Full Text Available Las empresas PYMES del sector metalmecánico de la ciudad de Olavarría aportan a su desarrollo económico pero presentan deficiencias a nivel de productividad, competitividad y en su gestión. Ante esta realidad se hace necesario intensificar el estudio de sus actividades y recursos para mejorar su situación actual. Por tanto, el objetivo es conocer la disponibilidad de recursos tangibles e intangibles y la forma en que los mismos son gestionados en cada una de las actividades empresariales. Para enmarcar el estudio de las actividades y el uso de recursos asociados se recurre a la cadena de valor, complementado con el enfoque basado en recursos. Se recolectan los datos mediante la aplicación de un instrumento, que indaga sobre el uso de recursos relacionados con las actividades primarias y de apoyo. Los recursos tangibles e intangibles son las variables independientes y las variables dependientes son las actividades primarias y de soporte. Luego, se profundiza el diagnóstico a través de un segundo instrumento, que define el nivel de madurez alcanzado en términos de competitividad. Como resultado del diagnóstico y caracterización del estado competitivo de empresas metalmecánicas de Olavarría se obtiene un grado de desarrollo, asociado al uso de los recursos con valores que van desde 49 al 72% para las actividades primarias y desde 55 al 67% para las de soporte. Al evaluar el aprovechamiento de los recursos en la totalidad de las actividades, a través del nivel de madurez, se obtiene un valor promedio asociado al nivel 2, correspondiente al uso ineficiente de recursos. Esto permite concluir que las mismas cuentan con recursos tangibles e intangibles, pero los mismos no son utilizados eficientemente para realizar sus actividades en pos de lograr una ventaja competitiva.

    Full Text Available Objetivos: Explicar la influencia de las actividades antrópicas en la variación de las capas de acumulación de nieve en los glaciares de la vertiente sur-occidental del nevado Huaytapallana de los Andes Centrales del Perú, en el ciclo hidrológico 2011-2012. Métodos: Se utilizó el método general hipotético – deductivo como guía en la investigación cuantitativa; el método del Thornthwaite para realizar el análisis hidrológico y clasificación climática de la zona; y el balance de masas como método para estimar la carga o descarga de nieve acumulado mediante balizas. Resultados: Se ha encontrado que las actividades antrópicas de turismo vivencial es una de las actividades principales que afectan al glaciar con el 60% de impacto. Las actividades de reforestación constituyen el 20% de impacto y el 10% la actividad de pastoreo. También los impactos de las actividades antrópicas a altitudes bajas en el glaciar son negativas, mientras que a altitudes superiores a los 5 000 msnm se registran menores impactos negativos. De igual manera se encontró una relación directa (coeficiente r= 0,97 entre el impacto a bajas altitudes de las masas glaciares. Conclusiones: La actividad de turismo vivencial que se realiza en varios sectores del nevado Huaytapallana, es una de las principales actividades antrópicas que está generando impactos negativos en el sistema glaciar al acelerar la pérdida de masa de nieve acumulado durante un ciclo hidrológico.

  15. China's Coal Methane: Actors, Structures, Strategies and their Global Impacts

    International Nuclear Information System (INIS)

    Chen, Ke; Charnoz, Olivier

    2012-12-01

    The need for China to alleviate its energy shortage, reduce its dependence on foreign sources and mitigate its climate impact is driving a dire quest for alternative fuels. Coal Mine Methane (CMM), in this context, holds significant potential. While the 11. Five-Year Plan aimed to capture and use 10 billion m"3 per year of CMM by 2010, the country achieved less than a quarter of this. This paper enquires into this puzzling outcome, which bears consequences for the world at large. China is indeed responsible for more than 40% of the world's total un-captured CMM emissions - which act as a greenhouse gas 21 times more potent than CO_2, and whose role in global warming is often underestimated, especially in short- and medium-term climate strategies. While the Chinese central government may have incentive to work towards promoting CMM, the benefits of such policies at the sub-national level are far from self-evident. National CMM policies can have significant economic and social costs at the local level, and thus their implementation can be jeopardized. Implementation of such policies is inherently ambiguous, conflicting, and as such, political. Current research on the Chinese CMM industry has largely focused on its techno-economic aspects, with little if any politico-institutional analyses. As for policy research on the larger Chinese energy sector, this seems sturdily to embody a top-down view: it mostly ends up blaming the country's decentralized governance structure and lack of a stringent implementation chain. Such top-down approaches do not help uncover 'the sinews of war': the range of less formal mechanisms, negotiations and agreements among the local actors, without which implementation does not in fact occur at the sub-national level. Nor do top-down research approaches facilitate inquiry into the way local stakeholders re-frame the meaning, content and impact of CMM policies. More generally, the top-down approaches fail to consider the significance of

  16. Actors or Spectators? Vulnerability and Critical Environmental Law

    Directory of Open Access Journals (Sweden)

    Andreas Philippopoulos‐Mihalopoulos

    2013-12-01

    Full Text Available The question of whether we as humans should remain spectators of the great theatre of ecological disaster or become actors is a false dichotomy. In this chapter, I argue that both are needed, since the critical distance of spectatorship does not annul the need for immersion in the ecological continuum. A tool in the realisation of this is the concept of vulnerability, which is here conceptualised as a space of ‘the middle’ (as opposed, emphatically, to ‘the centre’ and offers an opportunity to think away from the sterile debate on eco/anthropocentricity and from such limiting hierarchies as animal/human, human/environmental, natural/artificial. This new, vulnerable position of the middle allows the reconfiguration of ecological processes, and more specifically, the position of environmental law in relation to them. Environmental law now finds itself amidst a new, moving, ‘open ecology’ of social, biological and ecological processes. This is a new, radical conceptualisation of what I have called ‘critical environmental law’, based upon an epistemology of observation and an ontology of being part of this open ecology. Environmental law, in this light, is simultaneously reformulated as being an invitation to disciplinary and ontological openness and yet a call to remain immanent within existing legal structures. This finds expression in four critical environmental positions that set the stage for the further elaboration of a critical environmental law. La cuestión de si nosotros, como seres humanos, debemos seguir siendo espectadores del gran teatro de la catástrofe ecológica o convertirnos en actores es una dicotomía falsa. En este artículo se sostiene que ambos son necesarios, ya que la distancia crítica del espectador no anula la necesidad de una inmersión en el continuum ecológico. Una herramienta para la realización de esto es el concepto de vulnerabilidad, que aquí se concibe como un espacio 'intermedio' (en oposici

  17. Natural gas supply strategies for European energy market actors

    International Nuclear Information System (INIS)

    Girault, Vincent

    2007-06-01

    The liberalization of the European energy markets leads to the diversification of supplies. Hence, we analyse the natural gas importation problem in a power producer point of view. Upstream and downstream natural gas markets are concentrated. In this oligopoly context, our topic is to focus on strategies which modify natural gas sourcing price. This by studying the surplus sharing on the natural gas chain. A European firm can bundle gas and electricity outputs to increase its market share. Therefore, a bundling strategy of a power producer in competition with a natural gas reseller on the final European energy market increases upstream natural gas price. Bundling also acts as a raising rival cost strategy and reduces the rivals' profit. Profits opportunities incite natural gas producers to enter the final market. Vertical integration between a natural gas producer and a European gas reseller is a way, for producers, to catch end consumer surplus. Vertical integration results in the foreclosure of the power producer on the upstream natural gas market. To be active on the natural gas market, the power producer could supply bundles. But, this strategy reallocates the rent. The integrated firm on natural gas gets the rent of electricity market in expenses of the power producer. Then, a solution for the power producer is to supply gas and electricity as complements. Then, we consider a case where vertical integration is not allowed. Input price discrimination by a monopolist leads to a lower natural gas price for the actor which diversifies its supplying sources. Furthermore, a bundling strategy increases the gap between the price proposed to the firm which also diversify its output and the firm which is fully dependent from the producer to supply natural gas on final market.

  18. SRC: marker or actor in prostate cancer aggressiveness.

    2014-01-01

    A key question for urologic practitioners is whether an apparently organ-confined prostate cancer (PCa) is actually aggressive or not. The dilemma is to specifically identify among all prostate tumors the very aggressive high-grade cancers that will become life-threatening by developing extra-prostatic invasion and metastatic potential and the indolent cancers that will never modify a patient's life expectancy. A choice must be made between several therapeutic options to achieve the optimal personalized management of the disease that causes as little harm as possible to patients. Reliable clinical, biological, or pathological markers that would enable distinctions to be made between aggressive and indolent PCas in routine practice at the time of initial diagnosis are still lacking. The molecular mechanisms that explain why a PCa is aggressive or not are also poorly understood. Among the potential markers and/or actors in PCa aggressiveness, Src and other members of the Src kinase family, are valuable candidates. Activation of Src-dependent intracellular pathways is frequently observed in PCa. Indeed, Src is at the cross-roads of several pathways [including androgen receptor (AR), TGFbeta, Bcl-2, Akt/PTEN or MAPK, and ERK …], and is now known to influence some of the cellular and tissular events that accompany tumor progression: cell proliferation, cell motility, invasion, epithelial-to-mesenchymal transition, resistance to apoptosis, angiogenesis, neuroendocrine differentiation, and metastatic spread. Recent work even suggests that Src could also play a part in PCa initiation in coordination with the AR. The aim of this review is to gather data that explore the links between the Src kinase family and PCa progression and aggressiveness.

  5. The key role of supply chain actors in groundwater irrigation development in North Africa

    2017-09-01

    The role played by supply chain actors in the rapid development of groundwater-based irrigated agriculture is analyzed. Agricultural groundwater use has increased tremendously in the past 50 years, leading to the decline of water tables. Groundwater use has enabled intensification of existing farming systems and ensured economic growth. This "groundwater economy" has been growing rapidly due to the initiative of farmers and the involvement of a wide range of supply chain actors, including suppliers of equipment, inputs retailers, and distributors of irrigated agricultural products. In North Africa, the actors in irrigated production chains often operate at the margin of public policies and are usually described as "informal", "unstructured", and as participating in "groundwater anarchy". This paper underlines the crucial role of supply chain actors in the development of groundwater irrigation, a role largely ignored by public policies and rarely studied. The analysis is based on three case studies in Morocco, Tunisia and Algeria, and focuses on the horticultural sub-sector, in particular on onions and tomatoes, which are irrigated high value crops. The study demonstrates that although supply chain actors are catalyzers of the expansion of groundwater irrigation, they could also become actors in adaptation to the declining water tables. Through their informal activities, they help reduce market risks, facilitate credit and access to subsidies, and disseminate innovation. The interest associated with making these actors visible to agricultural institutions is discussed, along with methods of getting them involved in the management of the resource on which they depend.

    Performing a task alone or together with another agent can produce different outcomes. The current study used event-related functional magnetic resonance imaging (fMRI) to investigate the neural underpinnings when participants performed a Go/Nogo task alone or complementarily with another co-actor (unseen), whom was believed to be another human or a computer. During both complementary tasks, reaction time data suggested that participants integrated the potential action of their co-actor in their own action planning. Compared to the single-actor task, increased parietal and precentral activity during complementary tasks as shown in the fMRI data further suggested representation of the co-actor's response. The superior frontal gyrus of the medial prefrontal cortex was differentially activated in the human co-actor condition compared to the computer co-actor condition. The medial prefrontal cortex, involved thinking about the beliefs and intentions of other people, possibly reflects a social-cognitive aspect or self-other discrimination during the joint task when believing a biological co-actor is present. Our results suggest that action co-representation can occur even offline with any agent type given a priori information that they are co-acting; however, additional regions are recruited when participants believe they are task-sharing with another human.

    This article analyzes the sociodemographic network characteristics and antecedent behaviors of 119 lone-actor terrorists. This marks a departure from existing analyses by largely focusing upon behavioral aspects of each offender. This article also examines whether lone-actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone-actor terrorist events, other people generally knew about the offender's grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors' plots or events. Many but not all lone-actor terrorists were socially isolated. Lone-actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone-actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups. The implications for policy conclude this article. © 2013 American Academy of Forensic Sciences.

    2018-01-01

    There are basically two modeling approaches applicable to analyzing an actor-partner interdependence model: the multilevel modeling (hierarchical linear model) and the structural equation modeling. This article explains how to use these two models in analyzing an actor-partner interdependence model and how these two approaches work differently. As an empirical example, marital conflict data were used to analyze an actor-partner interdependence model. The multilevel modeling and the structural equation modeling produced virtually identical estimates for a basic model. However, the structural equation modeling approach allowed more realistic assumptions on measurement errors and factor loadings, rendering better model fit indices.

O experimento foi conduzido em casa de vegetação, utilizando-se o delineamento inteiramente casualizado, em esquema fatorial 4x2, considerando-se: quatro tratamentos de inoculação (controle não-inoculado, inoculado com Glomus clarum, inoculado com Glomus etunicatum e com a mistura dos dois fungos (Mix e duas condições de substrato (estéril e natural, com quatro repetições. As mudas de sabiá foram produzidas em bandeja de isopor, sendo transplantadas e inoculadas em vasos após treze dias da semeadura. Após trinta dias do transplantio foram realizadas avaliações de altura da parte áerea, diâmetro do colo, número de folíolos e porcentagem de sobrevivência. A inoculação com fungos micorrízicos arbusculares favoreceu o crescimento das mudas de sabiá em substrato da mineração de manganês, em condições naturais, principalmente quando se utilizou o Glomus etunicatum. No substrato esterilizado a inoculação com micorrizas arbusculares proporcionou a atenuação da toxidez de Mn nas mudas de sabiá favorecendo o crescimento das mesmas nestas condições.Arbuscular mycorrhiza on the growth of sabiá seedlings on a substrate from the manganese miningAbstract: Manganese (Mn is considered an essential micronutrient to plants but its excess can result in toxicity causing chlorosis and necrosis on

    The focus is on GAVE as an integral multi-actor process, as a collaboration process in which the parties have to find each other. The reason for this multi-actor approach is that the parties themselves have to realise the importance of sustainable energy. A multi-actor approach uses this crucial fact as the starting point. By means of the use of specific multi-actor methods and insights, it is possible during the collaboration process to develop a clear idea of the content of the joint path and the intended collaborative future, while paying specific attention to the individual roles of the players. Based on this, a well- considered and promising realisation path can be followed. The objective of this study is to illustrate - on the basis of two GAVE options - how the multi-actor approach can support the GAVE programme. In doing this, emphasis is placed on examples, the demonstration of added value of such an approach, and making recommendations for the future. Two experiments have been carried out on the basis of the Trinity approach. The Trinity approach is a set of methods specifically developed for supporting change processes which involve many parties (i.e. multi-actor processes). Trinity helps those involved to obtain a clear picture of both the route to be followed and the future situation to be aimed at. The term 'picture' must be understood literally: an important aspect of Trinity is the collaboration and communication with multi-actor models (also referred to as actorprints). By means of a diagram technique (figures and arrows) these models demonstrate the cohesion between the roles and activities of the various parties involved. The modelling process is instrumental in this; the actual result is that the image that is developed is formed and backed up by the participants in the process. Within these experiments, we have, so far, worked mainly in the shadow of the current GAVE process. A forceful participative use of the actor approach is

    Full Text Available Se puede hablar de sequía agropecuaria cuando la escasez de precipitaciones afecta el desarrollo fenológico de los cultivos o las necesidades de las actividades ganaderas. Las repercusiones sociales de este tipo de sequía dependen de la existencia de prácticas productivas y políticas rurales, que modifican la capacidad de los actores sociales para resistir y adaptarse a un periodo sin lluvias. En este trabajo se enumeran algunos de los factores que determinan la vulnerabilidad de los productorespecuarios de La Colorada, municipio localizado en el noroeste árido de México, frente a la sequía. Se identifican sus estrategias de respuesta ante el fenómeno y se discute la correspon-dencia entre las acciones promovidas por los programas de fomento agropecuario y las necesidades del sector ganadero local para enfrentar un evento de esta naturaleza.

    Full Text Available La refrigeración de la leche reduce el ritmo de multiplicación y actividad de los microorganismos, pero ha generado nuevos problemas relacionados con el crecimiento y la actividad de los microorganismos psicrótrofos, que son aquellos que crecen a temperaturas inferiores a 7 °C, independientemente de su temperatura óptima. Estos microorganismos producen enzimas termoestables que degradan algunos componentes de la leche deteriorando su calidad y la de sus derivados, y disminuyendo los rendimientos queseros. Con el fin de evaluar la actividad proteolítica de las bacterias psicrótrofas sobre las caseínas y su relación con la temperatura y tiempo de almacenamiento de la leche, se inocularon diferentes lotes de leche con este tipo de bacterias, hasta obtener recuentos de 104 y 105 unidades formadoras de colonia por mililitro (ufc/ml; como control se utilizó leche que no recibió inoculación con recuento de psicrótrofos de 103 ufc/ml. Después de almacenar la lechea4y7°Cdurante tres y seis días, se evaluó la actividad proteolítica sobre las caseínas. Al almacenar leche durante tres días a 4 y 7 °C, no se presentó actividad proteolítica cuando el recuento inicial de psicrótrofos era del orden de 103 ufc/ml, mientras que cuando dicho recuento fue superior a 104 ufc/ml se observó actividad proteolítica, siendo más intensa a 7 °C que a 4 °C. Con almacenamiento de seis días, solamente la leche conservada a 4 °C con recuento inicial de 103 ufc/ml no presentó actividad proteolítica, los demás tratamientos mostraron gran actividad proteolítica sobre la fracción de caseínas aumentando dicha actividad a medida que aumenta el grado de contaminación.

    2018-06-01

    This paper analyzes the actors in the climate change arena and their influence in directing Mexico toward policies that decrease greenhouse gas emissions, such as the carbon tax and climate change law. The network analysis of the agreement of these laws and public policies in Mexico is a lesson for any country that is in the process of designing and adopting environmental laws. The research is performed using a network analysis that is derived from interviews with various main actors and a discourse analysis of the media. Results show that actors do not coordinate their efforts-they meet frequently but in different inter-ministerial commissions-and do not enforce the same policies. The actors in the industry have formed strong coalitions against the carbon tax and the General Law on Climate Change, whereas international institutions have formed coalitions that support these policies and laws.

  16. [Can we consider the journalist an actor in suicide prevention?

    2016-10-01

    After more than 50 years of dedicated research, media coverage of suicide is now well known to have a significant influence on the suicide epidemiology. This influence is supposed to result from two opposite effects. The Werther effect (WE) refers to the robust increase of suicide rates following the publication of a suicide story. This specific kind of mass cluster implies a suggestion process, i.e. imitation of the depicted death by vulnerable persons. In contract, the preventive potential of medias has been labeled the "Papageno effect" (PE). Although more recently discovered and far less known, PE predicts that journalists can help prevent suicidal behaviors beyond a simple WE reduction. Because PE and WE directly bridge journalistic productions to suicidal events, several national and international health organisms (including the World Health Organization) started to see the media as new prevention opportunities. In this paper, we intend to assess the extent to which journalists can be considered as public health actors in the specific field of suicide prevention. Based on a critical review of the so-called Media effect studies, we explore the opportunities, limits and constraints of collaborating with media professionals for public health actions. For that purpose, we focus on the main strategy employed so far, namely providing recommendations for more cautious coverage of suicide. An overview of the efficacy of these recommendations serves not only as a starting point for understanding how public health and journalistic perspectives can confront, but also how they can be combined in a fertile way. Numerous suicide prevention organisms developed strategies in order to assist journalists in reporting suicide stories in a safer way. As a formal support to these strategies, around 30 national or international guides have been produced around the word, with the shared aim of reducing WE and, eventually, promoting PE.

    2014-06-01

    Guided by a dyadic view of children's peer behavior, this study assessed actor and partner effects of attachment security and temperament on young children's behavior with an unfamiliar peer. At 33 months of age, child-mother attachment security was assessed via a modified Strange Situation procedure, and parents reported on child temperament (anger proneness and social fearfulness). At 39 months, same-sex children (N = 114, 58 girls) were randomly paired, and child dyads were observed during 3 laboratory visits occurring over 1 month. Actor-partner interdependence models, tested via multilevel modeling, revealed that actor security, partner anger proneness, and acquaintanceship (e.g., initial vs. later visits) combined to predict child behavior. Actor security predicted more responsiveness to the new peer partner at the initial visit, regardless of partner anger proneness. Actor security continued to predict responsiveness at the 2nd and 3rd visits when partner anger was low, but these associations were nonsignificant when partner anger was high. Actor security also predicted a less controlling assertiveness style at the initial visit when partner anger proneness was high, yet this association was nonsignificant by the final visit. The findings shed light on the dynamic nature of young children's peer behavior and indicate that attachment security is related to behavior in expected ways during initial interactions with a new peer, but may change as children become acquainted.

    The assumed characteristics of individuals in the adult entertainment industry have been used to advocate positions for and against pornography. Although prior studies have investigated perceptions of porn actors, no data on the actual characteristics of this group exist. The present study compared the self-reports of 105 male and 177 female porn actors to the perceptions of 399 college students on childhood sexual abuse (CSA), self-esteem, work and non-work sexual behaviors, and safe sex issues. College students were asked to identify the characteristics associated with either a male or female porn star. College students provided underestimates for both female and male porn actors on self-esteem, age of first intercourse, lifetime number of partners outside of work, ideal experience in a romantic partner, concerns regarding sexually transmitted diseases (STDs), enjoyment of sex, and condom use during a first time sexual encounter, but overestimated earnings. Additional differences among male porn stars included an underestimate of the number of partners at work. For female porn stars, college students underestimated their enjoyment of work, the probability of catching an STD, and having unprotected sex. Although there were no significant differences on perceived rates of childhood abuse of porn actors, the incidence of CSA among the porn actor participants were within the ranges of the general population. The majority of college student stereotypes were not supported regarding the perceptions of porn actors. These findings were discussed within the context of attributing unfounded characteristics of individuals to an entire industry.

    We present an extension of the actor model with real-time, including deadlines associated with messages, and explicit application-level scheduling policies, e.g.,"earliest deadline first" which can be associated with individual actors. Schedulability analysis in this setting amounts to checking whether, given a scheduling policy for each actor, every task is processed within its designated deadline. To check schedulability, we introduce a compositional automata-theoretic approach, based on maximal use of model checking combined with testing. Behavioral interfaces define what an actor expects from the environment, and the deadlines for messages given these assumptions. We use model checking to verify that actors match their behavioral interfaces. We extend timed automata refinement with the notion of deadlines and use it to define compatibility of actor environments with the behavioral interfaces. Model checking of compatibility is computationally hard, so we propose a special testing process. We show that the analyses are decidable and automate the process using the Uppaal model checker.

    Full Text Available Performing a task alone or together with another agent can produce different outcomes. The current study used event-related functional magnetic resonance imaging (fMRI to investigate the neural underpinnings when participants performed a Go/Nogo task alone or complementarily with another co-actor (unseen, whom was believed to be another human or a computer. During both complementary tasks, reaction time data suggested that participants integrated the potential action of their co-actor in their own action planning. Compared to the single-actor task, increased parietal and precentral activity during complementary tasks as shown in the fMRI data further suggested representation of the co-actor’s response. The superior frontal gyrus of the medial prefrontal cortex was differentially activated in the human co-actor condition compared to the computer co-actor condition. The medial prefrontal cortex, involved thinking about the beliefs and intentions of other people, possibly reflects a social-cognitive aspect or self-other discrimination during the joint task when believing a biological co-actor is present. Our results suggest that action co-representation can occur even offline with any agent type given a priori information that they are co-acting; however additional regions are recruited when participants believe they are task-sharing with another human.

    Full Text Available Vietnam was one of the first countries to introduce the National REDD+ (Reduced Emissions from Deforestation and Forest Degradation Action Program in 2012. The country has recently revised the Program to aim for a more inclusive 2016–2020 strategy and a vision to 2030. This study explores how Vietnam policy actors view REDD+ policy development and their influence in these processes. The results can contribute to the discussion on how policy actors can effectively influence policy processes in the evolving context of REDD+ and in the types of political arrangements represented in Vietnam. We examined the influence of state and non-state actors on the 2012 National REDD+ Action Program (NRAP processes, and explored factors that may have shaped this influence, using a combination of document analysis and semi-structured interviews with 81 policy actors. It was found that non-state actors in REDD+ are still on the periphery of decision making, occupying “safe” positions, and have not taken either full advantage of their capacities, or of recent significant changes in the contemporary policy environment, to exert stronger influence on policy. We suggest that REDD+ policy processes in Vietnam need to be revitalized with key actors engaging collectively to promote the possibilities of REDD+ within a broader view of social change that reaches beyond the forestry sector.

    Performing a task alone or together with another agent can produce different outcomes. The current study used event-related functional magnetic resonance imaging (fMRI) to investigate the neural underpinnings when participants performed a Go/Nogo task alone or complementarily with another co-actor (unseen), whom was believed to be another human or a computer. During both complementary tasks, reaction time data suggested that participants integrated the potential action of their co-actor in their own action planning. Compared to the single-actor task, increased parietal and precentral activity during complementary tasks as shown in the fMRI data further suggested representation of the co-actor’s response. The superior frontal gyrus of the medial prefrontal cortex was differentially activated in the human co-actor condition compared to the computer co-actor condition. The medial prefrontal cortex, involved thinking about the beliefs and intentions of other people, possibly reflects a social-cognitive aspect or self-other discrimination during the joint task when believing a biological co-actor is present. Our results suggest that action co-representation can occur even offline with any agent type given a priori information that they are co-acting; however, additional regions are recruited when participants believe they are task-sharing with another human.

    Gill, Paul; Horgan, John; Deckert, Paige

    2014-01-01

    This article analyzes the sociodemographic network characteristics and antecedent behaviors of 119 lone-actor terrorists. This marks a departure from existing analyses by largely focusing upon behavioral aspects of each offender. This article also examines whether lone-actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone-actor terrorist events, other people generally knew about the offender’s grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors’ plots or events. Many but not all lone-actor terrorists were socially isolated. Lone-actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone-actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups. The implications for policy conclude this article. PMID:24313297

    Full Text Available Economic actors are the main trade player in the World Trade Organization, although, the relation between WTO and economic actor is built by trade regulation that is negotiated among the WTO Members. Nothing in the WTO regulates economic actors to involve directly in the WTO, especially in the WTO dispute settlement system. Nevertheless, the debate amongst experts regarding the involvement of economic actors in the WTO dispute settlement system is unavoidable. This article therefore discusses the possibility of the involvement of economic actors in the WTO dispute settlement system, whether there is legal and political point of views

  8. Not My Problem: Vicarious Conflict Adaptation with Human and Virtual Co-Actors

    Directory of Open Access Journals (Sweden)

    Michiel M. Spapé

    2016-04-01

    Full Text Available The Simon effect refers to an incompatibility between stimulus and response locations resulting in a conflict situation and, consequently, slower responses. Like other conflict effects, it is commonly reduced after repetitions, suggesting an executive control ability, which flexibly rewires cognitive processing and adapts to conflict. Interestingly, conflict is not necessarily individually defined: the Social Simon effect refers to a scenario where two people who share a task show a conflict effect where a single person does not. Recent studies showed these observations might converge into what could be called vicarious conflict adaptation, with evidence indicating that observing someone else’s conflict may subsequently reduce one’s own. While plausible, there is reason for doubt: both the social aspect of the Simon Effect, and the degree to which executive control accounts for the conflict adaptation effect, have become foci of debate in recent studies. Here, we present two experiments that were designed to test the social dimension of the effect by varying the social relationship between the actor and the co-actor. In Experiment 1, participants performed a conflict task with a virtual co-actor, while the actor-observer relationship was manipulated as a function of the similarity between response modalities. In Experiment 2, the same task was performed both with a virtual and with a human co-actor, while heart-rate measurements were taken to measure the impact of observed conflict on autonomous activity. While both experiments replicated the interpersonal conflict adaptation effects, neither showed evidence of the critical social dimension. We consider the findings as demonstrating that vicarious conflict adaptation does not rely on the social relationship between the actor and co-actor.

  9. Bridging centrality: A new indicator to measure the positioning of actors in R&D networks

    Energy Technology Data Exchange (ETDEWEB)

    Scherngell, T.; Wanzenboeck, I.; Berge, L.

    2016-07-01

    In the recent past, we can observe growing interest in the STI community in the notion of positioning indicators, shifting emphasis to actors in the innovation process and their R&D inter-linkages with other actors. In relation to this, we suggest a new approach for assessing the positioning of actors relying on the notion of bridging centrality (BC). Based on the concept of bridging paths, i.e. a set of two links connecting three actors across three different aggregate nodes (e.g. organisations, regions or countries), we argue that triangulation in networks is a key issue for knowledge recombinations and the extension of an actor's knowledge base. As bridges are most often not empirically observable at the individual level of research teams, we propose an approximated BC measure that provides a flexible framework for dealing with the aggregation problem in positioning actors. Hereby, BC is viewed as a function of an aggregate node's (i) participation intensity in the network, (ii) its openness to other nodes (i.e. the relative outward orientation of network links), and iii) the diversification of links to other nodes. In doing so, we provide an integrative perspective that enables us to achieve a better understanding of the positioning of certain actors in R&D networks. An illustrative example on the co-patent network of European regions demonstrates the performance and usefulness of our BC measure for networks constructed at the aggregated level, i.e. regions in our example. A region's outward orientation and the diversification of its network links moderates the influence of regional scale on network centrality. This is a major strength of the measure, and it paves the way for future studies to examine the role of certain aggregate node's, and, by this, contributes to the debate on positioning indicators in the STI context.

Com base nos valores percentuais de participação de cada fração nos teores totais, procedeu-se ao agrupamento das amostras similares por meio da análise de componentes principais (PCA. Houve basicamente duas formas de contaminação dos perfis de solo, sendo uma em decorrência das partículas das chaminés e a outra em função do acúmulo de rejeitos sólidos sobre os solos. A primeira foi mais prejudicial ao ambiente em razão dos maiores teores totais e de formas mais disponíveis no solo (solução mais trocável. De modo geral, houve maior associação de Pb aos carbonatos, seguida das frações residual e óxidos de Fe e Al de baixa cristalinidade. O Zn apresentou-se em formas mais insolúveis, aumentando a participação da fração residual nos teores totais. A PCA foi sensível às diferentes formas de Pb nos solos, pois promoveu o agrupamento das amostras, principalmente, em função da participação das formas trocáveis, ligadas aos óxidos de Fe e Al e ligadas aos carbonatos, em relação aos teores totais.

  14. Emotional labor actors: a latent profile analysis of emotional labor strategies.

    Science.gov (United States)

    Gabriel, Allison S; Daniels, Michael A; Diefendorff, James M; Greguras, Gary J

    2015-05-01

    Research on emotional labor focuses on how employees utilize 2 main regulation strategies-surface acting (i.e., faking one's felt emotions) and deep acting (i.e., attempting to feel required emotions)-to adhere to emotional expectations of their jobs. To date, researchers largely have considered how each strategy functions to predict outcomes in isolation. However, this variable-centered perspective ignores the possibility that there are subpopulations of employees who may differ in their combined use of surface and deep acting. To address this issue, we conducted 2 studies that examined surface acting and deep acting from a person-centered perspective. Using latent profile analysis, we identified 5 emotional labor profiles-non-actors, low actors, surface actors, deep actors, and regulators-and found that these actor profiles were distinguished by several emotional labor antecedents (positive affectivity, negative affectivity, display rules, customer orientation, and emotion demands-abilities fit) and differentially predicted employee outcomes (emotional exhaustion, job satisfaction, and felt inauthenticity). Our results reveal new insights into the nature of emotion regulation in emotional labor contexts and how different employees may characteristically use distinct combinations of emotion regulation strategies to manage their emotional expressions at work.

    2017-10-23

    This article provides an in-depth assessment of lone actor terrorists' attack planning and preparation. A codebook of 198 variables related to different aspects of pre-attack behavior is applied to a sample of 55 lone actor terrorists. Data were drawn from open-source materials and complemented where possible with primary sources. Most lone actors are not highly lethal or surreptitious attackers. They are generally poor at maintaining operational security, leak their motivations and capabilities in numerous ways, and generally do so months and even years before an attack. Moreover, the "loneness" thought to define this type of terrorism is generally absent; most lone actors uphold social ties that are crucial to their adoption and maintenance of the motivation and capability to commit terrorist violence. The results offer concrete input for those working to detect and prevent this form of terrorism and argue for a re-evaluation of the "lone actor" concept. © 2017 The Authors.

    Full Text Available We aim at mapping out a detailed framework that reveals the proportionate flow of cassava and its products along the value chain (VC. Furthermore, we aim at establishing the role of institutions and the linkages between institutions and other VC actors that influence the cassava VC in Uganda. We use both primary and secondary data obtained from four regions in Uganda. Results show that farmers, processors, transporters, traders, consumers and institutions are the major actors. There are four categories of institutions, viz, government, non-government, community based organisations and international agencies. Roles performed by institutions include: development and enforcement of policies, Research and Development (R&D, capacity building, and creation of market access linkages for cassava and its products. Findings reveal that there is no clear nexus and no coordination among farmers/producers, processors, traders, transporters and consumers. However, institutions are well coordinated and play various roles along the VC to influence the dynamics of actors. Policy-wise it is important to establish strong private-public partnerships to bridge the impaired linkages between the actors (farmers/producers, processors, traders, transporters, and consumers and institutions. Strong partnerships are envisaged to reduce the associated transaction costs amongst the actors.

    Full Text Available Nothing in the Uruguay Round mentions directly about rights of private economic actors. It seems that the relationship to private economic actors (or may be individual does not exist within the WTO Agreements, because as a general rule, private parties are not legal subjects of the international legal order. However, this article will prevail upon this situation, by looking closer at the essence of the WTO Agreements to discern the rights of private economic actors that derive from the WTO. The main question of this article is to what extent then Indonesia is dealing with the rights of private economic actors under the WTO Agreements? The background of this questionis because four years after ratifying the WTO Agreements, Indonesia has been facing what is arguably the most serious multidimensional crisis in 1997, some difficult situations have arisen from the crisis; therefore, the society hesitated to accept the open world trading system. The society seemed look askance to the implementation of the WTO Agreements. But Indonesian Government took major step to reduce the skepticism of society toward liberalization, by readjusting its national laws conform to the WTO Agreements with the intention to support the rights of national economic actors under the WTO Agreements in order to achieve total benefits of the WTO rules.

    Full Text Available El neologismo consum’actor (consumidor-actor es utilizado en diferentes espacios sociales para dirigirse a los consumidores susceptibles de ejercer una forma de compromiso través del consumo. El artículo muestra cómo la figura del consum’actor cumple una función de tipo ideal en la promoción del consumo de productos del comercio justo para el caso de promotores y consumidores franceses entrevistados en el marco de una investigación sociológica. Observando el mecanismo de recalificación del consumidor en consum’actor analizamos cómo se fabrica una argumentación tendiente a politizar ese acto de compra, interrogando la lógica de acción de los promotores. La reflexividad de los consumidores justos sobre las prácticas asociadas con el consum’actor permitió conocer los límites en la apropiación de esta figura. La porosidad de campos (mercado, consumo, política movilizados en la argumentación para su caracterización explica la distancia entre aquella función y los límites de su apropiación como figura social del compromiso ciudadano

    Actors are widely used in medical education as simulated patients. In this session, the role of actors was extended to 'simulated students' and facilitators in an introductory communication session. After an initial activity with the entire cohort of first-year students, groups of 20 students worked with either an actor or medical teacher in three activities. The activities aimed to raise students' awareness of the range of communication challenges in medical education and practice. After the session, students completed evaluation forms based on their experiences in the session. The results revealed no difference between students who were facilitated by actors or medical teachers in relation to meeting the learning objectives and their ratings of the usefulness of the activities to support learning. The actors who participated in this session were experienced in working with medical students. Their enhanced role provides students with an opportunity to identify with and reflect on the expertise of a lay teacher and to consider extending their definition of a learning opportunity to more informal encounters.

    Annual deforestation rates in the Brazilian Amazon fell by 77% between 2004 and 2011, yet have stabilized since 2009 at 5,000-7,000 km(2). We provide the first submunicipality assessment, to our knowledge, of actor-specific contributions to the deforestation slowdown by linking agricultural census and remote-sensing data on deforestation and forest degradation. Almost half (36,158 km(2)) of the deforestation between 2004 and 2011 occurred in areas dominated by larger properties (>500 ha), whereas only 12% (9,720 km(2)) occurred in areas dominated by smallholder properties (deforestation rates fell during this period by 68-85% for all actors, the contribution of the largest landholders (>2,500 ha) to annual deforestation decreased over time (63% decrease between 2005 and 2011), whereas that of smallholders went up by a similar amount (69%) during the same period. In addition, the deforestation share attributable to remote areas increased by 88% between 2009 and 2011. These observations are consistent across the Brazilian Amazon, regardless of geographical differences in actor dominance or socioenvironmental context. Our findings suggest that deforestation policies to date, which have been particularly focused on command and control measures on larger properties in deforestation hotspots, may be increasingly limited in their effectiveness and fail to address all actors equally. Further reductions in deforestation are likely to be increasingly costly and require actor-tailored approaches, including better monitoring to detect small-scale deforestation and a shift toward more incentive-based conservation policies.

  1. La actividad económica informal y el negocio de franquicia en Venezuela

    Full Text Available En el presente artículo se plantea el negocio de franquicia como una alternativa viable para canalizar la problemática de la informalidad laboral en Venezuela. Con base a un análisis documental-bibliográfico, semuestra la aplicabilidad de dichomodelo en un proceso de reconversión de la actividad económica informal en el país. Para lograrlo, se ha considerado la articulación entre diferentes conceptos económicos: el modelo de franquicia de conversión y la problemática de la economía informal en Venezuela, flagelo económico social presente en la realidad venezolana. Se concluye que un modelo de reconversión de la actividad económica informal representaría una alternativa para transformar esta actividad en el país, planteándose la conformación de una PYME con fortalezas financiera y operacional, con altos niveles de racionalidad, cuya actividad principal es ejecutada por otros individuos de manera informal; de esta forma se estructura una estrategia de crecimiento en función de la absorción de los ejecutores informales quienes, a través del financiamiento público o privado, concretan la conformación de una microempresa y la firma de un contrato tipo franquicia con la PYME.

The research was carried out in 2010 and 2011 in Cluj-Napoca, Romania; it uses multiple qualitative methods (focus-group and interviews and covers three layers of perception: candidate’s perception, employer’s perception and recruiter’s perception. Usually, the main social actors publically perceived as influencing age discrimination in the recruiting process are the employers (as the main responsible, some public institutions (as guardians and the candidates (as victims. The findings of the paper show that the number of social actors perceived as interested and with power by the main social actors (employers and candidates is much higher than the number classically targeted by researchers, reaching 20 or more

  8. Putting Gino's lesson to work: Actor-network theory, enacted humanity, and rehabilitation.

    Abrams, Thomas; Gibson, Barbara E

    2016-02-01

    This article argues that rehabilitation enacts a particular understanding of "the human" throughout therapeutic assessment and treatment. Following Michel Callon and Vololona Rabeharisoa's "Gino's Lesson on Humanity," we suggest that this is not simply a top-down process, but is cultivated in the application and response to biomedical frameworks of human ability, competence, and responsibility. The emergence of the human is at once a materially contingent, moral, and interpersonal process. We begin the article by outlining the basics of the actor-network theory that underpins "Gino's Lesson on Humanity." Next, we elucidate its central thesis regarding how disabled personhood emerges through actor-network interactions. Section "Learning Gino's lesson" draws on two autobiographical examples, examining the emergence of humanity through rehabilitation, particularly assessment measures and the responses to them. We conclude by thinking about how rehabilitation and actor-network theory might take this lesson on humanity seriously. © The Author(s) 2016.

    Pork safety is an important public health concern in Vietnam and is a shared responsibility among many actors along the pork value chain. We examined the knowledge, perceptions, and practices regarding food safety, disease, and health risk among selected pork value chain actors (slaughterhouse owners and workers, people living around slaughterhouses, pork sellers, consumers, and veterinary and public health staff) in three districts in Hung Yen Province, Vietnam. We randomly selected 52 pork value chain actors to be surveyed through questionnaires, observation checklists, key informant interviews, and focus group discussions. Most slaughterhouse workers acquired knowledge and experience of food safety through "learning by doing" rather than from training by a veterinary or public health professional. Both slaughterhouse worker and pork seller groups had some accurate perceptions about pig diseases and foodborne diseases; however, misperceptions of risk and, especially, of zoonoses were present. Furthermore, while workers and sellers often use cloths to dry the meat and clean equipment, they did not think this was a risk for meat contamination. Moreover, when sellers wear protective equipment, such as gloves, masks, or hats, consumers perceive that the sellers may have health issues they are trying to conceal and so consumers avoid buying from them. The perceived freshness of pork, along with trust in the seller and in the pork production process, were strong indicators of consumer preference. And yet, pork value chain actors tend to trust their own individual food safety practices more, rather than the practices of other actors along the chain. Veterinary and public health staff emphasized the gap between regulations and food safety practices. Education and training on food safety risks and proper handling are priorities, along with integrated and intensive efforts to improve food safety among pork value chain actors.

    Full Text Available Public policies are government programs that directly influence the citizens' lives. In the formulation and implementation of these policies, there is the presence of political and private actors. The final beneficiaries are between different types of private actors. Some laws require the government listen to society at the time of decision-making in public policy and in national conferences and public consultations. The final beneficiaries, actual users of these public policies have to reach some mechanisms of direct participation in the formulation of these policies, but the number of participants is smaller and doesn't influence in making government decisions.

  16. Effect of Acting Experience on Emotion Expression and Recognition in Voice: Non-Actors Provide Better Stimuli than Expected.

    Science.gov (United States)

    Jürgens, Rebecca; Grass, Annika; Drolet, Matthis; Fischer, Julia

    Both in the performative arts and in emotion research, professional actors are assumed to be capable of delivering emotions comparable to spontaneous emotional expressions. This study examines the effects of acting training on vocal emotion depiction and recognition. We predicted that professional actors express emotions in a more realistic fashion than non-professional actors. However, professional acting training may lead to a particular speech pattern; this might account for vocal expressions by actors that are less comparable to authentic samples than the ones by non-professional actors. We compared 80 emotional speech tokens from radio interviews with 80 re-enactments by professional and inexperienced actors, respectively. We analyzed recognition accuracies for emotion and authenticity ratings and compared the acoustic structure of the speech tokens. Both play-acted conditions yielded similar recognition accuracies and possessed more variable pitch contours than the spontaneous recordings. However, professional actors exhibited signs of different articulation patterns compared to non-trained speakers. Our results indicate that for emotion research, emotional expressions by professional actors are not better suited than those from non-actors.

    2014-12-01

    Full Text Available This study aims at investigating the linguistic representation of male and female social actors in the Four Corners 4 textbook, drawing on CDA. More specifically, van Leeuwen’s (1996 framework, which highlights the connection of linguistic and social practices, is used as the analytical framework to examine gendered social actors in this English language teaching (ELT textbook. To this end, content analysis was done to explore the frequency and proportion of each social actor. Quantitative and qualitative data analysis showed that there were some differences, though not statistically significant, between males and females regarding substitution, individualization, and activation. Males, in contrast with females, were included more as active and famous actors in social circumstances and they were more individualized. In addition, they were more activated through circumstantialization and participation. On the other hand, the case of formalization was mostly observed for males. Moreover, males and females were distributed equally in the textbook in terms of classification, genericization, and collectivization. The results reveal that the gender bias still exists, though to a small degree, in this ELT textbook, which is taught as a substitution for the previous ELT textbooks in many language schools in Iran.
