  1. Artisanal salt production in Aveiro/Portugal - an ecofriendly process.

    Rodrigues, Carolina M; Bio, Ana; Amat, Francisco; Vieira, Natividade


    Solar salinas are man-made systems exploited for the extraction of salt, by solar and wind evaporation of seawater. Salt production achieved by traditional methods is associated with landscapes and environmental and patrimonial values generated throughout history. Since the mid-twentieth century, this activity has been facing a marked decline in Portugal, with most salinas either abandoned or subjected to destruction, making it necessary to find a strategy to reverse this trend.It is, however, possible to generate revenue from salinas at several levels, not merely in terms of good quality salt production, but also by obtaining other products that can be commercialized, or by exploring their potential for tourism, and as research facilities, among others. Furthermore, with an adequate management, biodiversity can be restored to abandoned salinas, which constitute important feeding and breeding grounds for resident and migratory aquatic birds, many of which are protected by European Community Directives.The aims of this manuscript are to present a brief overview on the current state of sea salt exploitation in Portugal and to stress the importance of recovering these salinas for the conservation of this particular environment, for the regional economy, the scientific community and the general public. The Aveiro salina complex is presented in detail, to exemplify salina structure and functioning, as well as current problems and potential solutions for artisanal salinas. PMID:22053788

  2. Tsunami Impact from a 1755-like event in the Aveiro Region, Portugal

    Lemos, Catarina R.; Omira, Rachid; Pinheiro, Luis M.; Baptista, Maria A.; Quaresma, Luis S.; Garrido, Carla


    In this study, we present 5m-resolution tsunami flooding maps for the Aveiro region, W. Central Portugal. Aveiro is known to have been impacted by the 1st November 1755 earthquake and tsunami. At that time this portion of the coast had almost no constructions nor population but eversince geomorphological changes took place, and there has been a very large population increase living in constructions extremely close to the shore. As such it is important to model and evaluate the potential impact that a similar event to the 1755 earthquake would have in this area at present. Tsunami flooding maps were computed using a digital elevation model produced from the present-day bathymetric and topographic data including bathymetric surveys, LiDAR and photogrammetric data. Tsunami scenarios were generated considering different solutions for the 1755 earthquake seismic source, in faults constrained by multibeam and multichannel seismic data. The modeling of the tsunami propagation was performed with a validated non-linear shallow water model. To compute inundation, we considered four levels of nested grids with resolutions ranging from 320m to 5m. The tsunami-associated flood is discussed in terms of flow depth, run-up height and maximum inundation area. The Ria de Aveiro is characterized by both flattened relief and significant tidal amplitude range, which can contribute to an important variation in flooding due to tsunami-tide interaction. Therefore, the effect of the tide variation on the extent of tsunami inundation is also discussed. Results are compared with the historical descriptions of the consequences in Aveiro. An event similar to the one from 1755 would cause tsunami run-up heights above one meter within the Ria de Aveiro. The Aveiro oceanic coast would also be strongly affected. The results obtained can be used to identify the potential tsunami inundation areas in Aveiro, which is important for the Portuguese tsunami emergency management system. Keywords

  3. Mercury pollution in Ria de Aveiro (Portugal): a review of the system assessment

    Pereira, M E; Lillebø, A. I.; Pato, P.; Válega, M.; J. P. Coelho; Lopes, C. B.; Rodrigues, S.; Cachada, A.; Otero, M; Pardal, M.A.; Duarte, A.C.


    The Ria de Aveiro (Portugal) is a coast al lagoon adjacent to the Atlantic Ocean and it has an inner bay (Laranjo bay) that received a highly contaminated effluent discharged by a mercury cell chlor-alkali plant from the 1950s until 1994. The aim of this study is to review in a holistic way several research studies that have been carried out in the Ria de Aveiro, in order to evaluate the remobilization of the mercury accumulated within the system and the recovery of the lagoon. The spatial di...

  5. Trophic web structure and ecosystem attributes of a temperate estuarine system (Ria de Aveiro, Portugal

    Eva García-Seoane


    Full Text Available Estuaries are among the most productive ecosystems and simultaneously among the most threatened by conflicting human activities, which damage their ecological functions. Describing and attempting to understand the structure and functioning of estuaries is an essential step for maintaining and restoring the quality of estuarine ecosystems. The objective of this study was to obtain insights into the ecosystem structure and functioning of Ria de Aveiro. The study area is a coastal lagoon located on the Northwest Atlantic coast of Portugal, which is connected to the sea through an artificial channel. The ECOPATH software was used to create a static balanced trophic food web model of the tidal part of Ria de Aveiro. The model considers 26 functional groups, including birds, fish, invertebrates, seagrasses, zooplankton, phytoplankton and detritus. Few adjustments were necessary for the input parameters because most of the data were based on direct observations or compiled from literature based on the study site. The trophic interactions within the food web of Riade Aveiro and the transference of energy between functional groups were quantitatively represented. Finally, the keystone index was defined for each functional group.

  6. Benthic biodiversity patterns in Ria de Aveiro, Western Portugal: Environmental-biological relationships

    Rodrigues, Ana Maria; Quintino, Victor; Sampaio, Leandro; Freitas, Rosa; Neves, Ramiro


    This study characterizes the macrobenthic gradients in Ria de Aveiro, Western Portugal. Ria de Aveiro is the meeting place of a number of river basins, resulting in a transition system of complex geometry, with channels running parallel to the coast line, north and south of the entrance, but also inland, creating an intricate system of navigation channels, islands and intertidal sand and mudflats. This renders unique characteristics to this system within the framework of transitional waters. The study was based on the analysis of samples from 248 sites, covering the full salinity gradient and the entire channel system. A total of 120 taxa in more than 76,350 specimens were identified. The most abundant and frequent taxa were all annelids, namely Alkmaria romijni, Streblospio shrubsolii, Tharyx sp., Tubificoides benedii, Nereis diversicolor, Capitella sp., Pygospio elegans, Polydora ligni and an unidentified oligochaete. The spatial distribution of the fauna was found to be mainly related to hydrodynamics and the salinity gradient, whereas sediment grain-size characteristics were much less important. Shear stress, flux, current velocity, salinity and sediment redox potential were the environmental variables which best related to the biological data. Benthic assemblages succeed from the euhaline pole, at the entrance, to the limnetic poles, located in the inner parts of the channels. In this succession, mean abundance increased from the outward to the inward assemblages but species richness and diversity were higher in intermediate assemblages. These descriptors decrease abruptly in the limnetic areas. Using the M-AMBI index, the ecological quality of Ria de Aveiro revealed moderate, poor and bad status. However, the ecological status spatial trend closely followed the benthic assemblages succession, their species richness and diversity, indicating the need for proper reference conditions and inter-calibration exercises in the transition waters before final

  7. Support mechanisms for oil spill accident response in costal lagoon areas (Ria de Aveiro, Portugal)

    Oliveira, Eduardo R.; Silveira, Bruno; Alves, Fátima L.


    Oil spill accidents can be caused by several risk factors associated to maritime transport and port activities, which cannot always be predicted or controlled. Therefore, it is essential to support prevention and contingency plans, whose effectiveness is crucial to produce adequate responses and minimize resulting impacts. Ria de Aveiro (Portugal) is a wide coastal lagoon, within a densely populated area, representing a concentration of important biodiversity resources and several economic activities. This paper presents alternative methodologies to support the optimization of civil protection assets in the occurrence of oil spill events and the results of their application on a section area of the Aveiro Lagoon, using an established geographic information system database containing crucial data. The presented methodologies are based on the Environmental Sensitivity Index developed by the North American National Oceanic and Atmospheric Administration (USA) and the Global Vulnerability Index which were applied on the Bay of Biscay (Spain). However, during the development of this work, neither of these methodologies was considered to entirely assess the study area in its full extent, which led to the need to adapt and define a bespoke approach. The introduced changes include extra categories in shoreline classification, an adapted physical vulnerability index for coastal lagoons, differentiated aspects for highly protected status areas, qualitative assessment of socioeconomic features and an access and operability index created to support emergency operation response. The resulting maps are the subject of analysis, in which considerations regarding control and cleanup methods are introduced, together with guidelines for further integration in local risk management strategies.

  8. Participação escolar: representações dos alunos do 3º ciclo de Aveiro (Portugal School participation: representations of 3rd cycle pupils in Aveiro (Portugal

    Ana Paula Pedro


    Full Text Available Este artigo propõe uma reflexão sobre a relação intrínseca entre democracia e educação, particularmente na vertente relacionada com a participação dos discentes nas decisões da escola. Neste sentido e, no quadro do regime de autonomia das escolas portuguesas, importa identificar os espaços formais e informais que são proporcionados aos jovens na tomada de decisões da vida organizativa da escola para compreendermos o papel desta na promoção e capacitação dos jovens para o exercício de uma cidadania ativa. O modo de vida democrático constrói-se através de oportunidades de aprendizagem acerca do mesmo, nomeadamente pela vivência de experiências participativas no contexto escolar. Em 2009, realizámos um estudo, no âmbito da dissertação de uma dissertação de mestrado em Ciências da Educação da Universidade de Aveiro, Portugal, em duas escolas públicas do ensino básico, do Concelho de Aveiro, abrangendo uma população composta por 240 alunos do 8º e 9º ano de escolaridade e 14 delegados de turma. Os resultados mostram que os alunos possuem uma débil participação formal e informal, apesar de o Decreto-lei n. 115-A/98 prever a possibilidade de cada escola, no âmbito da sua autonomia, poder promover e criar espaços de efetiva participação dos alunos. A análise dos instrumentos de autonomia das escolas estudadas revela que a participação dos alunos é assumida, ainda, como um ideal e não já como um efetivo projeto de concretização. Concluímos, pois, que as escolas ainda mantêm uma centralização das decisões nos professores, verificando-se, por parte dos alunos, uma participação formal, passiva e ritualizada.This article proposes a reflection about the intrinsic relationship between democracy and education, particularly in the aspects related to the participation of students in the school decisions. In this sense, and within the sphere of the autonomy regime of Portuguese schools it is important to

    Rangel, LF; Santos, MJ


    This is the first host record of Gymnophallus choledochus metacercariae infecting the polychaete Diopatra neapolitana in the Aveiro estuary (Portugal). The metacercariae were round unencysted, and their morphology is similar to that presented by metacercariae harbored by Nereis diversicolor and Cerastoderma edule, although they are larger in size. In D. neapolitana, the prevalence and mean intensity of the infection was very high, at 100% and 202 +/- 139 metacercariae per host, respectively, ...

  11. Juncus maritimus root biochemical assessment for its mercury stabilization potential in Ria de Aveiro coastal lagoon (Portugal).

    Anjum, Naser A; Duarte, Armando C; Pereira, Eduarda; Ahmad, Iqbal


    Major endogenous biochemical properties can make plants ideal agents for metal/metalloid-contaminated site cleanup. This study investigates the biochemistry of Juncus maritimus (Lam) roots for its high mercury (Hg) stabilization potential in the sediments of the Ria de Aveiro coastal lagoon (Portugal), which received Hg-rich effluents from a chlor-alkali industry between 1950 and 1994. J. maritimus plants were collected at a reference (R) site and three sites with the highest (L1), moderate (L2), and the lowest (L3) Hg contamination levels. The highest Hg-harboring/stabilizing J. maritimus roots at L1, exhibited significantly elevated damage endpoints (H2O2; lipid peroxidation, LPO; electrolyte leakage, EL; protein oxidation, PO; proline) which were accompanied by differential changes in H2O2-metabolizing defense system components (ascorbate peroxidase, catalase, glutathione peroxidase, glutathione S-transferase), glutathione reductase and the contents of both reduced and oxidized glutathione. Trends in measured endpoints reached maximum levels at L1 followed by L2 and L3. Cross-talks on root-Hg status and the studied biochemical traits revealed (a) high Hg-accrued elevations in oxidative stress as an obvious response; (b) Hg-stabilization potential of J. maritimus roots as a result of a successful mitigation of elevated high Hg-induced H2O2, and its anomalies such as LPO, EL, and PO; and (c) the induction of and a fine synchronization between non-glutathione and glutathione-based systems. Overall, the study unveiled biochemical mechanisms underlying root tolerance to Hg burden-accrued anomalies which, in turn, helped J. maritimus during Hg-stabilization. PMID:25175353

  12. Response of Benthic Foraminifera to Organic Matter Quantity and Quality and Bioavailable Concentrations of Metals in Aveiro Lagoon (Portugal)

    Martins, Maria Virgínia Alves; Silva, Frederico; Laut, Lazaro L. M.; Frontalini, Fabrizio; Clemente, Iara M. M. M.; Miranda, Paulo; Figueira, Rubens; Sousa, Silvia H. M.; Dias, João M. Alveirinho


    This work analyses the distribution of living benthic foraminiferal assemblages of surface sediments in different intertidal areas of Ria de Aveiro (Portugal), a polihaline and anthropized coastal lagoon. The relationships among foraminiferal assemblages in association with environmental parameters (temperature, salinity, Eh and pH), grain size, the quantity and quality of organic matter (enrichment in carbohydrates, proteins and lipids), pollution caused by metals, and mineralogical data are studied in an attempt to identify indicators of adaptability to environmental stress. In particular, concentrations of selected metals in the surficial sediment are investigated to assess environmental pollution levels that are further synthetically parameterised by the Pollution Load Index (PLI). The PLI variations allowed the identification of five main polluted areas. Concentrations of metals were also analysed in three extracted phases to evaluate their possible mobility, bioavailability and toxicity in the surficial sediment. Polluted sediment in the form of both organic matter and metals can be found in the most confined zones. Whereas enrichment in organic matter and related biopolymers causes an increase in foraminifera density, pollution by metals leads to a decline in foraminiferal abundance and diversity in those zones. The first situation may be justified by the existence of opportunistic species (with high reproduction rate) that can live in low oxic conditions. The second is explained by the sensitivity of some species to pressure caused by metals. The quality of the organic matter found in these places and the option of a different food source should also explain the tolerance of several species to pollution caused by metals, despite their low reproductive rate in the most polluted areas. In this study, species that are sensitive and tolerant to organic matter and metal enrichment are identified, as is the differential sensitivity/tolerance of some species to

  13. Diopatra neapolitana (Polychaeta: Onuphidae) as a second intermediate host of Gymnophallus choledochus (Digenea: Gymnophallidae) in the Aveiro estuary (Portugal): distribution within the host and histopathology.

    Rangel, L F; Santos, M J


    This is the first host record of Gymnophallus choledochus metacercariae infecting the polychaete Diopatra neapolitana in the Aveiro estuary (Portugal). The metacercariae were found unencysted, and their morphology is similar to that presented by metacercariae harbored by Nereis diversicolor and Cerastoderma edule, although they are larger in size. In D. neapolitana, the prevalence and mean intensity of the infection was very high, at 100% and 202 +/- 139 metacercariae per host, respectively, suggesting that this polychaete is the most suitable host for G. choledochus in the Aveiro estuary. In terms of distribution within the host, the metacercariae were found almost exclusively in the branchial segments (97.4%). This, in conjunction with the close relationship between the mean intensity and branchial surface area, suggests that the branchiae may be the site of entry into the polychaete. Within the branchial segments, the sites selected by the metacercariae are the parapodia (68.9%), where they are mostly located inside the setal sac, and the longitudinal muscles (22.3%), causing hypertrophy and rupture of the muscle bundles, respectively. These histological changes suggest a reduction in polychaete mobility, which should aid the easy predation of infected hosts by birds and thus facilitate the continuity of the G. choledochus life cycle.

  14. Mercury behaviour in the water column of an impacted coastal lagoon: Ria de Aveiro (Portugal) as a case study

    Ramalhosa, Elsa; Pereira, Eduarda; Duarte, Armando


    As mercury presents high toxicity and is of great concern when dealing with protection of human health, mercury pollution related issues are the main subject of this work. At first, two general themes are discussed, namely: I) Mercury: highlights of physicochemical and biogeochemical properties of interest and of the main natural and anthropogenic metal sources; and II) Biogeochemical cycling of mercury in the water column of natural waters. Secondly, a case study performed in Ria de Aveiro (...

  15. [The emergence and institutionalization of sexology in Portugal: processes, actors, and specificities].

    Alarcão, Violeta; Machado, Fernando Luís; Giami, Alain


    Based on Bourdieu's field theory, this article analyzes the emergence and institutionalization of sexology as a science and profession in Portugal, identifying relevant institutions, actors, and professional practices and discussing its relations and specificities. The analysis begins by contextualizing the emergence of modern Western sexology in order to comprehend the Portuguese case in the international sexology context. The second section describes the social, cultural, and institutional factors that have driven the professionalization of sexology. The third section describes the emergence of Portuguese sexology and its principal historical milestones, institutions, and actors. Finally, the article discusses some implications of this process for the role of sexology as a science and profession. The study reveals the dynamics of national and international processes in the field, in the transition from a holistic perspective of sexology to the hegemony of sexual medicine, and sheds light on its mechanisms of legitimation as a transdisciplinary science of sexuality, suggesting future perspectives.

  16. Investigaciones realizadas en la Universidad de Aveiro sobre caracterización mecánica de las construcciones existentes en adobe en Portugal y propuestas de rehabilitación y refuerzo. Resultados alcanzados

    Varum, H.


    Full Text Available In Portugal, mainly in Aveiro region, adobe buildings were the prevailing construction system during the first half of the 20th century. Presently, the legacy that results from the patrimony built in that period is still significant –about 30% of the existing constructions in the region– and, moreover, it is comprised by a large number of patrimonial buildings of high historical, cultural and architectural value. A marked negligence in the rehabilitation of this patrimony has been observed in the last decades, and has resulted in the actual damage state presented by many of these constructions, which generally resulted in unfavourable safety and durability conditions. However, in the last years, an increasing interest in the conservation and rehabilitation of the adobe patrimony in the region, associated with environmental, economical and patrimonial safeguard factors, has been demonstrated by public administrative entities and also by the private sphere. In face of this reality, which emphasizes the need and importance of developing intervention strategies that may enable, by rehabilitation and/or strengthening, extending the lifespan of these structures, a group of researchers of the University of Aveiro has been developing a multidisciplinary study on the adobe construction in Portugal. The main objective of this research work is the creation of a test results database that may support rehabilitation and/or strengthening interventions, and also the study of solutions for the improvement of the structural behaviour of these constructions. In this sense, the research carried out was constituted seeking to contribute to the knowledge of this type of adobe masonry, focused mainly on their rehabilitation, providing information to the professionals and institutions working in the field of heritage conservation.

  17. Ecology of the polychaete Nereis diversicolor in the Canal de Mira (Ria de Aveiro, Portugal): Population dynamics, production and oogenic cycle

    Abrantes, António; Pinto, Fátima; Moreira, Maria Helena


    The population of Nereis diversicolor O.F. Müller was studied in 1993 and 1994 at three intertidal areas along the estuarine gradient in the Canal de Mira (Ria de Aveiro). The population dynamics, secondary production and growth were followed for the 2-year period, whereas in the second year, a study on the oogenic cycle was also carried out. For the population dynamics and production studies, core samples were collected monthly at each site, and for the study of the oogenic cycle, medium size and large individuals were sampled from the sediment. Mean annual densities were higher (573-718 ind.m -2) at a station located in the middle zone of the channel, followed by the outer (190-275 ind.m -2) and the innermost (43-94 ind.m -2) stations. A cohort analysis by `Bhatta' software enabled the separation of the cohorts present at each date, and two cohorts were followed from recruitment to extinction. The secondary production ranged from 15.9 to 74.2 g ash free dry weight.m -2.year -1 and the P/ overlineBratio from 4.4 to 7.9. The average body growth rate varied between 0.16 and 0.20 mm.d -1 for worms longer than 2 cm. Two recruitment seasons were detected each year. Two spawning periods were also observed, one in the spring and the other in early autumn.

  19. Oxidative stress status, antioxidant metabolism and polypeptide patterns in Juncus maritimus shoots exhibiting differential mercury burdens in Ria de Aveiro coastal lagoon (Portugal).

    Anjum, Naser A; Duarte, Armando C; Pereira, Eduarda; Ahmad, Iqbal


    This study assessed the oxidative stress status, antioxidant metabolism and polypeptide patterns in salt marsh macrophyte Juncus maritimus shoots exhibiting differential mercury burdens in Ria de Aveiro coastal lagoon at reference and the sites with highest, moderate and the lowest mercury contamination. In order to achieve these goals, shoot-mercury burden and the responses of representative oxidative stress indices, and the components of both non-glutathione- and glutathione-based H2O2-metabolizing systems were analyzed and cross-talked with shoot-polypeptide patterns. Compared to the reference site, significant elevations in J. maritimus shoot mercury and the oxidative stress indices such as H2O2, lipid peroxidation, electrolyte leakage and reactive carbonyls were maximum at the site with highest followed by moderate and the lowest mercury contamination. Significantly elevated activity of non-glutathione-based H2O2-metabolizing enzymes such as ascorbate peroxidase and catalase accompanied the studied damage-endpoint responses, whereas the activity of glutathione-based H2O2-scavenging enzymes glutathione peroxidase and glutathione sulfo-transferase was inhibited. Concomitantly, significantly enhanced glutathione reductase activity and the contents of both reduced and oxidized glutathione were perceptible in high mercury-exhibiting shoots. It is inferred that high mercury-accrued elevations in oxidative stress indices were obvious, where non-glutathione-based H2O2-decomposing enzyme system was dominant over the glutathione-based H2O2-scavenging enzyme system. In particular, the glutathione-based H2O2-scavenging system failed to coordinate with elevated glutathione reductase which in turn resulted into increased pool of oxidized glutathione and the ratio of oxidized glutathione-to-reduced glutathione. The substantiation of the studied oxidative stress indices and antioxidant metabolism with approximately 53-kDa polypeptide warrants further studies. PMID:24488555

  1. Portugal.


    Portugal's 1983 population of 10.04 million was growing at .7%/year. 97% were Roman Catholic, 80% were literate, and 4.1 million were in the labor force in 1984. Portugal is mountainous north of the Tagus River and consists of rolling plains in the central south. The Azores and Madeira islands belong to Portugal but enjoy considerable autonomy. Portugal's dependency of Macau on the Chinese coast is an autonomous entity under Portuguese administration. The former teritories of Goa and Portuguese Timor were annexed by India and Indonesia respectively in 1961 and 1976, and the former territories in Africa achieved independence in 1974 and 1975. Portugal, 1 of the oldest states in Europe, traces its modern history to A.D. 1140 when the 1st king was crowned. The approximate present day boundaries were secured in 1249. Portugal eventually became a massive colonial empire with territories in Africa and Latin America and outposts in the Far East. The Portuguese Republic replaced the monarchy in 1910. After some years of instability, Antonio Salazar became prime minister, and with his successor, ruled Portugal as an authoritarian "corporate" state for 42 years. An almost bloodless coup in 1974 led to establishment of a parliamentary democracy. The 4 main organs of national government are the presidency, the prime minister and council of ministers, the assembly of the republic, and the courts. Portugal's gross domestic product (GDP) in 1984 was $19.4 billion, and per capita income was $1930. After almost a decade of rapid growth, the economy declined in the mid 1970s due to disruption after the 1974 revolution and the large influx of refugees from Portugal's former colonies in Africa. Growth resumed in the late 1970s, but structural problems and an often adverse international economic climate have slowed progress. The proportion of the labor force in agriculture has dropped from 42% to 24.4% since 1960. Agricultural production now contributes only 8.8% to the GDP, and a

    During 2011, Portugal experienced a strong reduction of electricity demand. With a decrease of 2.3%, the total consumption was 50.5 TWh (1). Due to a mild winter season, the most relevant renewable generation facilities (hydro and wind) experienced a strong production reduction in comparison with 2010. In 2011, Portuguese wind farms produced 21 GWh less than the previous year. It is only because of the decrease in consumption that wind penetration achieved a value of 18%. The growth of the wi...

  5. O Senhor Director: fragmentos de uma história de actores e práticas escolares em Portugal

    Carvalho Luís Miguel


    Full Text Available Este artigo procura analisar a trajectória das orientações e das práticas de administração de um director de uma escola portuguesa, entre meados de 1950 e de 1970. Por meio dela igualmente se pretende aumentar a compreensão de um conjunto de circunstâncias, processos e significados que marcaram, nesse período, a própria trajectória do sistema educativo escolar em Portugal, particularmente a que diz respeito ao alargamento da escolaridade obrigatória e à unificação dos estudos pós-primários. O texto articula seis fragmentos de uma investigação de maior escala que tomou a forma de um estudo de caso histórico-organizacional, e na qual se concretizou a história de um grupo de professores de uma disciplina escolar. As narrativas que se apresentam resultam do recurso a fontes de evidência orais (entrevistas e escritas (documentos oficiais, imprensa pedagógica, documentos pessoais de professores, documentos do arquivo do estabelecimento escolar. Os fragmentos que aqui se apresentam e que ganham unidade em torno da figura do director resultam também do uso de matrizes micropolíticas para a análise do quotidiano escolar, razão pela qual neles se enfatizam fenómenos ligados quer à coordenação quer à disputa ao redor de interesses ideológicos e materiais, bem como às estratégias empregues na ampliação ou defesa de margens de autonomia no controlo do trabalho de administração de estabelecimentos escolares. Sobressaem, por isso, os processos que guindaram uma escola e um director ao estatuto de singulares e modelos, no âmbito da rede escolar portuguesa de então.

  10. Salt Fluxes in a Complex River Mouth System of Portugal

    Vaz, Nuno; Lencart e Silva, João D.; Dias, João Miguel


    Measurements of velocity and salinity near the mouth and head of the Espinheiro channel (Ria de Aveiro lagoon, Portugal) are used to study the local variation of physical water properties and to assess the balance, under steady conditions, between the seaward salt transport induced by river discharge and the landward dispersion induced by various mixing mechanisms. This assessment is made using data sampled during complete tidal cycles. Under the assumption that the estuarine tidal channel is...

  11. Impact of freshwater inflow on bacterial abundance and activity in the estuarine system Ria de Aveiro

    Santos, Luísa; Vaz, Leandro; Marcial Gomes, Newton C.; Vaz, Nuno; Dias, João Miguel; Cunha, Ângela; Almeida, Adelaide


    The influence of freshwater flow on bacterial communities in the estuarine system Ria de Aveiro (Portugal) was investigated at two sites differently impacted by river inputs, representative of the marine and brackish water zones of the estuary. Sampling events were clustered based on hydrological features. The hydrodynamic was simulated with a Lagrangian model and related to microbiological parameters. Estuarine bacteria responded to different freshwater regimes developing distinct patterns of abundance and activity at the marine and brackish water zones. A circulation pattern induced by high river inflow produced vertical stratification in the marine zone, promoting a seaward flux of bacterioplankton, and stimulating the import of riverine phytoplankton and particle-attached bacteria to the brackish water zone. Advective transport and resuspension processes contributed to a 3-times increase in abundance of particle-attached bacteria during intense freshwater inputs. Additionally, bacterial activity in the estuary was controlled by inorganic nitrogen, responding to different freshwater inputs, which, in association with different prevailing sources of organic substrates induced significant changes in bacterial production. The dynamic and main controlling factors of bacterial communities are clearly impacted by freshwater inputs. Therefore, significant changes in the recycling of nutrients by microbial activities can be expected from alterations in freshwater inputs either related to global climate change or regional hydrological regimes.

  18. Expectations of a group of Portuguese pregnant women in the districts of Viseu and Aveiro regarding motherhood.

    Coutinho, Emília de Carvalho; Rocha, Ana Maria Anjos; Silva, Alcione Leite da


    Motherhood is a complex phenomenon, supplementedwith expectations about the new reality, the hopes of all going well, taking into account the expected care. In order to meet the needs of the Portuguese expectant mother, it is necessary to know what she deems essential for herself and her family, so that strategies may be developed to facilitate the transition process. This study was intended to gain insight into fulfilled and unfulfilled expectations of health care in motherhood with a group pregnant females in Portugal. This is a qualitative, exploratory and descriptive study, with 22 Portuguese women belonging to the Clusters of Health Care Centers of the districts of Viseu and Aveiro. The data was collected through semi-structured interviews and analysed using content analysis proposed by Bardin, supported by QSR NVivo 10. It was observed that fulfilled expectations surpassed those unmet, especially in terms of high quality health care and competent health care professionals. Regarding unfulfilled expectations, they mainly refer to maternity incentives, with an emphasis on the wish of greater financial familly supportfrom the government. PMID:27557007

  19. Determinants of Actor Rationality

    Ellegaard, Chris

    Industrial companies must exercise influence on their suppliers (or supplier actors). Actor rationality is a central theme connected to this management task. In this article, relevant literature is studied with the purpose of shedding light on determinants of actor rationality. Two buyer......-supplier relations are investigated in a multiple case study, leading to the proposal of various additional factors that determine and shape actor rationality. Moreover a conceptual model of rationality determinants in the buyer-supplier relation is proposed, a model that may help supply managers analyse and...... understand actor rationalities. Finally managerial implications are discussed....

    Vieira, L; Silvestre-Ferreira, A C; Fontes-Sousa, A P; Balreira, A C; Morchón, R; Carretón, E; Vilhena, H; Simón, F; Montoya-Alonso, J A


    Dirofilaria immitis is endemic in Portugal. Several studies have reported the presence of canine heartworm disease, although no previous studies on feline infections have been published. The aim of this study was to determine the prevalence of D. immitis in cats and dogs from central and northern Portugal. Blood samples from 434 cats were tested for circulating anti-D. immitis and anti-Wolbachia antibodies. Furthermore, 386 dogs were tested for circulating D. immitis antigens. Overall feline seroprevalence was 15%, while canine prevalence was 2.1%. The highest feline seroprevalences of 18.7% and 17.6% were found in Aveiro and Viseu, respectively, while the highest canine prevalences of 8.8% and 6.8% were found in Coimbra and Aveiro, respectively. Cats and dogs showing respiratory signs presented higher prevalences of 24.4% and 17%, respectively, while 50% of cats with gastrointestinal signs were seropositive. The present study confirms the seropositivity of D. immitis in the feline population in central and northern Portugal, and suggests the importance of including heartworm disease in the list of differential diagnoses of cats and dogs showing clinical signs compatible with the disease.

  12. Soil versus lichen analysis on elemental dispersion studies (north of Portugal)

    Chemical elements contents in topsoil and lichens sampled at regular intervals in the north of Portugal were obtained by using both comparative and k0 methods of instrumental neutron activation analysis. The topsoil chemical composition was studied in an attempt to discriminate between natural background and anthropogenic inputs, as well as to eliminate the influence of soil on the lichen composition. Topsoil maps revealed the existence of areas with anomalous concentrations due: (1) to natural causes (inherited from the initial rock) especially Cr in Tras-os-Montes and (2) anthropogenic influence, namely Aveiro-Estarreja area for Cr and Co associated to high values of Fe. Br contents in topsoil decrease from the coast to the interior explained by the sea influence (wet deposition). Exceptional concentration values of As, Zn, and W were found in one particular topsoil (Nogueira do Cravo), probably due to aerial inputs originated in mining activities. The enrichment factors (E.F.) in Parmelia sulcata relative to topsoil clearly showed that lichens are fingerprints of atmospheric pollution, especially for Cr, Zn, As, Br, Sb, and W. The following areas with anomalous E.F. in lichens were detected: (1) Viana do Castelo - Braga for Cr, Sb, (Zn and Br), (2) Tras-os-Montes for Br, (3) Porto for As and Zn, and (4) Aveiro-Estarreja for As, Cr, Sb, and W. Identification of industrial pollution sources was possible. (author)

  20. Salt fluxes in a complex river mouth system of Portugal.

    Nuno Vaz

    Full Text Available Measurements of velocity and salinity near the mouth and head of the Espinheiro channel (Ria de Aveiro lagoon, Portugal are used to study the local variation of physical water properties and to assess the balance, under steady conditions, between the seaward salt transport induced by river discharge and the landward dispersion induced by various mixing mechanisms. This assessment is made using data sampled during complete tidal cycles. Under the assumption that the estuarine tidal channel is laterally homogeneous and during moderate tidal periods (except for one survey, currents and salinity data were decomposed into various spatial and temporal means and their deviations. Near the channel's mouth, the main contributions to the salt transport are the terms due to freshwater discharge and the tidal correlation. Near the channel's head, this last term is less important than the density driven circulation, which is enhanced by the increase in freshwater discharge. The remaining terms, which are dependent on the deviations from the mean depth have a smaller role in the results of salt transport. The computed salt transport per unit width of a section perpendicular to the mean flow is in close agreement to the sum of the advective and dispersive terms (within or very close to 12%. An imbalance of the salt budget across the sections is observed for all the surveys. Considerations are made on how this approach can inform the management of hazardous contamination and how to use these results to best time the release of environmental flows during dry months.

  4. Self-Recovering Sensor-Actor Networks

    Kamali, Maryam; Petre, Luigia; Sere, Kaisa; 10.4204/EPTCS.30.4


    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...

  14. tradicional: Conflictos y actores laborales

    Héctor Lucena


    Full Text Available Este artículo forma parte de una línea de investigación más general que se ocupa de analizar las transformaciones en las Relaciones de Trabajo. El presente documento centra su atención en los cambios que experimenta la Organización del Trabajo y como ellos repercuten en la conflictividad laboral. Se parte de reconocer que la relación capital-trabajo es de naturaleza conflictiva, pero que los mecanismos de convivencia entre las partes y todo el marco regulatorio, permiten y facilitan el desenvolvimiento y la convivencia productiva. Sin embargo, los cambios en la Organización del Trabajo que reducen la fuerza de trabajo y lesionan conquistas históricas de los trabajadores, estimulan el desarrollo de conflictos colectivos, los que materializan en tanto existan constituidos los actores laborales. En el proceso de investigación seguido en esta línea, se revisa la literatura pertinente, se analizan casos de la realidad laboral venezolana reciente vía hemeroteca y entrevistas, privilegiándose la huelga de Sidor en el 2004. Se concluye, destacando que los cambios que paulatinamente se emprenden desde la empresa para modificar la Organización del Trabajo, erosionan la capacidad de respuesta de los actores laborales representativos de los trabajadores.

  15. Fully Abstract Game Semantics for Actors

    Wang, Yong


    Along the way paved by the recent concurrent game semantics for process algebra CCS and $\\pi$-calculus, based on the basic characteristics of the actor computational model and the very reductive semantics for actors, we establish a fully abstract concurrent game semantics for actors by borrowing the algebraic structure from CCS. This semantics can both be seen as an innocent presheaf semantics, and a concurrent game semantics.

  19. Is Portugal potentially insolvent

    Eric Dor


    The primary surplus ratio which is required to stabilize the public debt ratio depends on assumptions about the future rate of growth of nominal GDP and implicit interest rates levels. Under the official scenario of a long term nominal growth rate of 4% and an unchanged implicit interest rate of 3.5%, Portugal may even have a small deficit of the primary balance. However, under realistic forecasts of a 2.5% rate of nominal growth, and an implicit interest rate at 4.5%, debt stabilization requ...

These actors are public actors who can be incentive or financing actors (ADEME, ANR) or research institutions (CNRS, CEA, university and engineering schools, IFP, INERIS, INRETS), private actors like industrial groups (Air Liquide, AREVA, GDF Suez, Total, PSA Peugeot Citroen, Renault, Saint-Gobain, SNECMA, ST Microelectronics, 3M, Veolia Environnement) or small companies (Alca Torda Applications, Axane, CETH2, Helion, MaHytec, N-GHY, PaxiTech, Sertronic, ULLIT). It also presents the HyPAC platform created by the AFH2 and ADEME), the AFH2 (the French Association for Hydrogen), and regional initiatives

  2. Long-term monitoring of a mercury contaminated estuary (Ria de Aveiro, Portugal): the effect of weather events and management in mercury transport

    Coelho, J. P.; Pato, P.; Henriques, B.; A. Picado; Lillebo, A. I.; Dias, J.M.; Duarte, A.C.; Pereira, M. E.; Pardal, M.A.


    The main aim of this research was to assess the mercury transport from an estuarine basin with a background of anthropogenic contamination during a spring tidal cycle (year 2009) and compare it with two previous tidal cycles (years 1994 and 1999), as part of a long-term monitoring program. Results showed that effective mercury transport occurs both in the dissolved and particulate fractions (0.18 and 0.20 kg per tidal cycle, respectively), and despite an overall decrease in enviro...

  6. Ultraviolet radiation watch in Portugal

    Ultraviolet radiation monitoring in Portugal started in the eighties using a broadband type detector installed at Lisbon. Currently, the Portuguese Institute of Meteorology has set up a new ultraviolet network using both spectral and broadband detectors covering most of the mainland territory and Madeira islands. Ultraviolet monitoring is complemented by the ultraviolet Index forecasting program started in 1999. A brief historical view, methodology and some results of the ultraviolet watch in Portugal are shown. (author)

  7. Women in Portugal.

    Barbosa, M


    Prior to 1974, women in Portugal were restricted by the Penal Code and had little organizational power. Women's groups were formed within the Catholic Church to teach women about cooking, child care, and home economics. There was no contact with international women's groups. The press only reported events such as bra burning. 80% of all illiterates in Portugal are women. The conditions of Portuguese women are described after the revolution of April 25, 1974. Present roles are discussed for work, health, education, religion, trade unions and political parties, and women's organizations. The Women's Liberation Movement (WLM) appeared in May 1974 among a heterogenous group of women in Lisbon who were concerned about the oppression of women. WLM made feminist issues public amid ridicule and promoted the declaration of equal rights for women in the 1976 Republic Constitution and in the Family Code. Wage discrimination became illegal in 1979. Women represent 32.8% of the labor force. Unemployment is particularly high among women and is increasing. Women's wages and levels of skill are the lowest. The Christian Democratic government is actively engaged in a campaign to keep women at home and has formed the special Ministry of Family Affairs, which encourages large families and women's home activity in order to save jobs for men. There is a crisis in education: large class sizes and limited number of schools. Child care for the working mother is expensive when available and rarely available. An obstacle to women's rights has been the role of the Catholic Church, which fought equal rights legislation, condemned the Family Code and divorce laws, forbade the practice of contraception, and supported the movement against abortion. Only 1 member of government is a women, and she is considered a token. Trade unions have a women's section, but little attention is given to the problems of women. Women's groups within larger organizations have little autonomy. Those with autonomy

  8. Journalism : new media, new actors - new ethics?

    Fidalgo, Joaquim


    The traditional field of journalism has been facing major challenges in recent years, either because new actors have entered that field (professional journalists actually lost the monopoly of searching, gathering, editing and diffusing news in the public sphere), or because the old actors are increasingly asked to play new roles. The social demand for more public participation in the process of handling news and information, added to the fabulous possibilities of communication brought by the ...

  11. Bad Actors Criticality Assessment for Pipeline system

    Nasir, Meseret; Chong, Kit wee; Osman, Sabtuni; Siaw Khur, Wee


    Failure of a pipeline system could bring huge economic loss. In order to mitigate such catastrophic loss, it is required to evaluate and rank the impact of each bad actor of the pipeline system. In this study, bad actors are known as the root causes or any potential factor leading to the system downtime. Fault Tree Analysis (FTA) is used to analyze the probability of occurrence for each bad actor. Bimbaum's Importance and criticality measure (BICM) is also employed to rank the impact of each bad actor on the pipeline system failure. The results demonstrate that internal corrosion; external corrosion and construction damage are critical and highly contribute to the pipeline system failure with 48.0%, 12.4% and 6.0% respectively. Thus, a minor improvement in internal corrosion; external corrosion and construction damage would bring significant changes in the pipeline system performance and reliability. These results could also be useful to develop efficient maintenance strategy by identifying the critical bad actors.

  12. Effective Location Management of Mobile Actors in Wireless Sensor and Actor Networks

    Nauman Aslam


    Full Text Available Recent years have witnessed an increasing availability of heterogeneous sensor networks that consist of a large number of resource constrained nodes (sensors and a small number of powerful resource rich nodes (actors. Such heterogeneous Wireless Sensor Actor Network (WSANs offer improvement of sensor networks' capacity/coverage, energy conservation and network lifetime. This paper investigates the case where sensors are organized into clusters and mobile actors are used for maintaining an energy efficient topology by periodically manipulating their geographical position. We present an elegant technique that allows actor nodes to find an optimal geographical location with respect to their associated cluster heads such that the overall energy consumed is minimized. The proposed technique includes a weighted cost function based on the residual energy levels of cluster heads that allows the mobile actor to optimally fine-tune its geographical location. We present simulation results that demonstrate a significant increase of network lifetime over the traditional cluster based WSN deployments.

  13. New Actors and Alliances in Development

    Richey, Lisa Ann; Ponte, Stefano


    ‘New actors and alliances in development’ brings together an interdisciplinary group of scholars exploring how development financing and interventions are being shaped by a wider and more complex platform of actors than usually considered in the existing literature. The contributors also trace...... governments. Despite the diversity of these actors and alliances, several commonalities arise: they are often based on hybrid transnationalism and diffuse notions of development responsibility; rather than being new per se, they are newly being studied as practices that are now coming to be understood...... as ‘development’; and they are limited in their ability to act as agents of development by their lack of accountability or pro-poor commitment. The articles in this collection point to images and representations as increasingly important in development ‘branding’ and suggest fruitful new ground for critical...

  16. Off-Policy Actor-Critic

    Degris, Thomas; Sutton, Richard S


    This paper presents the first actor-critic algorithm for off-policy reinforcement learning. Our algorithm is online and incremental, and its per-time-step complexity scales linearly with the number of learned weights. Previous work on actor-critic algorithms is limited to the on-policy setting and does not take advantage of the recent advances in off-policy gradient temporal-difference learning. Off-policy techniques, such as Greedy-GQ, enable a target policy to be learned while following and obtaining data from another (behavior) policy. For many problems, however, actor-critic methods are more practical than action value methods (like Greedy-GQ) because they explicitly represent the policy; consequently, the policy can be stochastic and utilize a large action space. In this paper, we illustrate how to practically combine the generality and learning potential of off-policy learning with the flexibility in action selection given by actor-critic methods. We derive an incremental, linear time and space complexi...

  20. The moral problem of worse actors

    Scott Wisor


    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.

    Silva, Filipe Carreira da


    Sociology in Portugal provides the first English-language account of the history of sociology in Portugal from 1945 to the present day. Banned by the fascist regime until 1974, the institutionalization of sociology as an academic discipline came relatively late. Understanding academic disciplines as institutionalized struggles over meaning, Filipe Carreira da Silva gives a genealogy of sociology in Portugal from its origins in the political-administrative interstices of a dictatorship, throug...

  17. Test Case Generation of Actor Systems

    Albert Albiol, Elvira; Arenas Sánchez, Purificación; Gómez Zamalloa, Miguel


    Testing is a vital part of the software development process. It is even more so in the context of concurrent languages, since due to undesired task interleavings and to unexpected behaviours of the underlying task scheduler, errors can go easily undetected. Test case generation (TCG) is the process of automatically generating test inputs for interesting coverage criteria, which are then applied to the system under test. This paper presents a TCG framework for actor systems, which consists of...

  18. Towards feature selection in actor-critic algorithms

    Rohanimanesh, Khashayar; Roy, Nicholas; Tedrake, Russell Louis


    Choosing features for the critic in actor-critic algorithms with function approximation is known to be a challenge. Too few critic features can lead to degeneracy of the actor gradient, and too many features may lead to slower convergence of the learner. In this paper, we show that a wellstudied class of actor policies satisfy the known requirements for convergence when the actor features are selected carefully. We demonstrate that two popular representations for va...

At the table, the ESO Director General, Catherine Cesarsky , and the Portuguese Minister of Science and Technology, José Mariano Gago . In his speech, the Portuguese Minister of Science and Technology, José Mariano Gago , stated that "the accession of Portugal to ESO is the result of a joint effort by ESO and Portugal during the last ten years. It was made possible by the rapid Portuguese scientific development and by the growth and internationalisation of its scientific community." He continued: "Portugal is fully committed to European scientific and technological development. We will devote our best efforts to the success of ESO". Catherine Cesarsky , ESO Director General since 1999, warmly welcomed the Portuguese intention to join ESO. "With the accession of their country to ESO, Portuguese astronomers will have great opportunities for working on research programmes at the frontiers of modern astrophysics." "This is indeed a good time to join ESO", she added. "The four 8.2-m VLT Unit Telescopes with their many first-class instruments are nearly ready, and the VLT

  2. Portugal's Petrogal eyes expansion amid continuing privatization

    Portugal's recently privatized state oil company Petrogal is about to embark on a major expansion worldwide. That comes against the backdrop of major change in Portugal's energy sector and the rocky road to Petrogal's partial privatization. Despite the controversy, there remain opportunities for foreign companies investing in Portugal's energy sector. The most attractive opportunities are in Portugal's downstream petroleum sector and in the country's continuing campaign to develop its natural gas industry. Typical of the latter is Portugal's participation in the Trans-Maghreb gas pipeline megaproject. The paper discusses the background to privatization, its current status, Petrogal strategy, modernization of refineries, a joint partnership with Venezuela, constraints, energy policy program, gas pipeline privatization, and concerns of the gas industry

  3. Geology and religion in Portugal

    Carneiro, Ana; Simoes, Ana; Diogo, Maria Paula; Mota, Teresa Salomé


    This paper addresses the relationship between geology and religion in Portugal by focusing on three case studies of naturalists who produced original research and lived in different historical periods, from the eighteenth to the twentieth century. Whereas in non-peripheral European countries religious themes and even controversies between science and religion were dealt with by scientists and discussed in scientific communities, in Portugal the absence of a debate between science and religion within scientific and intellectual circles is particularly striking. From the historiographic point of view, in a country such as Portugal, where Roman Catholicism is part of the religious and cultural tradition, the influence of religion in all aspects of life has been either taken for granted by those less familiar with the national context or dismissed by local intellectuals, who do not see it as relevant to science. The situation is more complex than these dichotomies, rendering the study of this question particularly appealing from the historiographic point of view, geology being by its very nature a well-suited point from which to approach the theme. We argue that there is a long tradition of independence between science and religion, agnosticism and even atheism among local elites. Especially from the eighteenth century onwards, they are usually portrayed as enlightened minds who struggled against religious and political obscurantism. Religion—or, to be more precise, the Roman Catholic Church and its institutions—was usually identified with backwardness, whereas science was seen as the path to progress; consequently men of science usually dissociated their scientific production from religious belief.

  4. Policy analysis of multi-actor systems

    Enserink, Bert; Kwakkel, Jan; Thissen, Wil; Koppenjan, Joop; Bots, Pieter


    Policy analysts love solving complex problems. Their favorite problems are not just technically complex but also characterized by the presence of many different social actors that hold conflicting interests, objectives, and perceptions and act strategically to get the best out of a problem situation. This book offers guidance for policy analysts who want to assess if and how their analysis could be of help, based on the premise that problem formulation is the cornerstone in addressing complex problems. This book positions policy analysis within the theories on processes of policy making, and f

  6. Diásporas y transiciones en la Teoría del Actor-Red Diasporas and transitions in Actor-Network Theory

    Blanca Callén


    Full Text Available Este texto es una presentación del monográfico Diásporas y transiciones en la teoría del actor-red. Sus páginas presentan las principales características de esta teoría, una manera de entender sus orígenes y una descripción de su presente estableciendo un paralelismo con la etnometodología. El texto finaliza con una valoración del estado de la teoría del actor-red en España y un comentario sobre un congreso que llevó el título de Presente y futuro de la teoría del actor-red y que constituye el embrión del presente monográfico. En el texto se defiende una tesis muy simple: la teoría del actor-red nace con cierta relevancia para el pensamiento social en el momento en que se difracta en una miríada de usos y aplicaciones diferentes. El principal corolario de este hecho también es muy sencillo: la gran diferencia entre la teoría del actor-red y otras propuestas del pensamiento social es su permanente estado de diáspora y transición.
    This paper is an introduction to the monograph titled Diasporas and Transitions in the Actor-Network Theory. Drawing a parallel with ethnomethodology, its pages present the main features of this theory, a way to figure out its origins and a description of its present. The text ends with a brief look at the state of art of actor-network theory in Spain and an appraisal of a meeting titled Present and Future of Actor-Network Theory, which is the origin of our monograph. In this paper we put forward a very simple idea: Actor-Network Theory was born with certain relevance in Social Sciences when it diffracted in a myriad of different uses and applications. The main corollary of such an idea is also straightforward: the very difference between Actor-Network Theory and other perspectives in Social Sciences resides in the permanent diaspora and transition of the former.

  7. Climate change projections for precipitation in Portugal

    Andrade, C.; Santos, J. A.


    The strong irregularity of precipitation in Portugal, which may e.g. trigger severe/extreme droughts and floods, results in a high vulnerability of the country to precipitation inter-annual variability and to its extremes. Furthermore, dryer future climates are projected for Portugal, though there has also been some growing evidence for a strengthening of precipitation extremes. Due to the central role played byprecipitation on many socio-economic sectors and environmental systems, regional climate change assessments for precipitation in Portugal are necessary. This study is focused on analyzing climate change projections for seasonal (3-month) precipitation totals and their corresponding extremes over mainland Portugal. Taking into account the strong seasonality of the precipitation regimes in Portugal, winter (DJF) and summer (JJA) are considered separately. Precipitation datasets generated by a 16-member ensemble of regional climate model experiments from the ENSEMBLES project are used. Percentile-based indices of precipitation are computed and analyzed for a recent past period (1961-2000) and for a near future period (2041-2070). Results for the R5p, R50p and R95p indices highlight significant projected changes in precipitation, with a clear distinction between northwestern Portugal and the rest of the country in both seasons. Overall, precipitation is projected to decrease in both seasons, particularly over northwestern Portugal in winter, despite some significant regional differences. Although precipitation is projected to decrease in most cases, extremely high seasonal precipitations (above the 95th percentile)areexpected to increase in winter.

  8. Transnational citizenship: Latin Americans in Portugal

    Beatriz Padilla


    Full Text Available This article is a reflection upon the exercising of transnational citizenship as a consequence of international migration, applied to Latin Americans resident in Portugal. In order to do this we have adopted the concept of transnational citizenship, as its malleability allows us to consider the whole concept of countries of origin and destination and the influence of bilateral and international relations. We ask how transnational citizenship is exercised in the European Union, Ibero-American and, particularly, Portuguese spaces, and whether it is affected by the economic crisis in Europe and, in particular, Portugal, by analysing the cases of Argentines, Brazilians and Uruguayans living in Portugal.

  13. [Carbon monoxide intoxications in Portugal].

    Sá, Márcia Christel; Rodrigues, Rui Paulo; Moura, Daniel


    The prevalence of carbon monoxide intoxication in the World shows that this is a common situation. In Portugal, there are no concrete data available in literature and its incidence remains unknown. Currently, the use of hyperbaric oxygen is a valid therapeutic for carbon monoxide poisoning management. However, its effectiveness and its proper handling are still controversial. The first aim of this study was to estimate the incidence of carbon monoxide intoxication in Portugal and to analyze its demographic characteristics. The second objective of this work was to evaluate the possible change in the type of treatment applied in areas near de hyperbaric chamber of Unidade Local de Saúde de Matosinhos, since its opening in June 2006. To achieve these objectives, we conducted a survey on admissions data for carbon monoxide intoxication occured between January first, 2000 and December 31, 2007. These data was collected in seven hospitals and in the Administração Central do Sistema de Saúde, I.P. Nationally, 621 hospitalizations were recorded, which represents an incidence of 5,86/100000 in 8 years. In the seven hospitals, there were 93 hospitalizations due to carbon monoxide intoxication during the same period of time. There was a peak of incidence during winter, between November and March and there was a similar distribution in men (47,3%) and women (52,7%). Since June 2006, date of opening of the hyperbaric chamber, the Unidade Local de Saúde de Matosinhos, E.P.E. recorded a sharp increase in the number of hospitalization for carbon monoxide intoxication. The number of admissions in the 19 months after the chamber opening was double the number of all cases occurred in that institution in the 65 months prior. We concluded that, in Portugal, carbon monoxide intoxication is an uncommon situation but it´s still an important cause of hospitalization. The referral of cases to the Unidade Local de Saúde de Matosinhos, E.P.E. since the opening of hyperbaric chamber

  19. Optometry in Portugal: a historical perspective

    Teixeira, Eduardo; Baptista, António M. G.; Sousa, Raul A. R. C.


    The establishment and development of optometry in Portugal resulted from the committed work of many individuals and institutions. These efforts have had good results in terms of raising the public's awareness of the major role played by optometrists in primary eye care. Back in the late 80's higher education in optometry was started. Ten years ago the results of scientific research on the topic first became available and are now also contributing to the success of optometry in Portugal. In regard to the optometry profession, specific regulations are to be discussed in the national parliament. The Associação de Profissionais Licenciados de Optometria (APLO), as the professional organization representing optometrists in Portugal, has been critically important in this process. This article will present an overview of the history of optometry in Portugal, of change in the foreseeable future and of the APLO's experience and activities.

  20. Wind power costs in Portugal

    Saleiro, C. [Univ. of Minho, Dept. of Biological Engineering (Portugal); Araujo, M.; Ferreira, P. [Univ. of Minho, Dept. of Production and Systems (Portugal)


    In a way to reduce the external energy dependence, increasing also the investments in renewable energy sources and aiming for the concretization of the European renewable objectives, the Portuguese government defined a goal of 5100 MW of installed wind power, up to 2012. If the drawn objectives are accomplished, by 2010 the wind power share may reach values comparable to leading countries like Denmark, Germany or Spain. The Portuguese forecasts also indicate a reinforcement of the natural gas fired generation in particular through the use of the combined cycle technology, following the European tendency. This analysis sets out to evaluate the total generating cost of wind power and CCGT in Portugal. A life cycle cost analysis was conducted, including investment costs, O and M costs, fuel costs and external costs of emissions, for each type of technology. For the evaluation of the externalities ExternE values were used. The results show that presently the wind power production cost is higher than the CCGT one, at least from the strictly financial point of view. CCGT costs increase significantly when charges for externalities are included. However, they only reach levels higher than the equivalents for wind power for high externality costs estimations. This partially results from the low load factor of the wind farms in Portugal and also from the low emission levels of the gas fired technology used in the comparison. A sensitive analysis of the technical and economical parameters was also conducted. Particular attention was given to the natural gas prices due to the possible increase over time. The fuel escalation rate is the parameter that has larger effects on the final costs. It was verified that the total cost of wind plant is more influenced by the load factor than the total cost of CCGT. (au)

    Eduardo Gudynas


    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.

  6. Private Actors on the Rise? The Role of Non-State Actors in Compliance with International Institutions

    Börzel, Tanja


    (Transnational) private actors have a significant role in ‘global governance’. But their influence varies significantly, both across time and issues. The major challenge for theorizing about non-state actors in world politics is not only to demonstrate that they matter but explain where, when, and how they matter. This paper takes issue with these challenges by looking at the role of private actors in compliance with international institutions. The first part of the paper clarifies the concep...

  7. Between authority and media actor. The municipality as a news actor on the Internet

    Signe Bock Segaard


    Full Text Available

    The article illuminates how local authorities as news actors fill their websites with content. This is done through a study of how active the local authorities are as news actors on the Internet, what kinds of electronic news dissemination they do in practice, and to what degree they experience dilemmas in electronic news dissemination. The analytic point of departure is the tension between a journalistic ideal of news mediation relates to democratic values and a strategic ideal of communication related to branding. Empirically the analysis is based on data from several Danish and Norwegian municipalities which are considered as particularly active on the Internet. Finally the article discusses municipal news mediation on the Internet in the light of the municipality as a public authority as well as a market actor, a service provider, and as a democratic actor. The question is in what way municipal news dissemination on the Internet is a democratic gain. The article shows that the work with news dissemination on the Internet to some degree is characterized by professionalization, centralization, and bureaucratization. The democratic gain of municipal news dissemination is an empirical question and related to the criteria of news selection (in practice. Furthermore the article shows that some municipalities have a more strategic focus while others have a more journalistic focus but one focus does not rule out the other.

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



    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

    A first set of article comments and discusses the various stakes and challenges of the 21. Conference of Parties (COP 21): the negotiation process which resulted in a synthesis which is to be signed by 95 States in Paris, the elaboration of an Agenda of solutions with the commitment of enterprises and local authorities, the issue of international financing as some promises remained not kept for the support to adaptation of developing countries. A second set of articles addresses the involved actors and their technological or economic challenges: the needed evolution of energy (electricity, heat, gas, fuel) producers away from fossil energies to reduce greenhouse gas emissions, the strategy of the French company Engie in the field of photovoltaic, wind and more generally renewable energies, innovating trends of decentralisation of energy production (offshore wind energy, hydrogen, plasma torch, flexible photovoltaic arrays, the wind tree, the floating wind turbine, new technologies for solar arrays), the perspectives for industrial sectors concerned by energy transition (with the example of Schneider Electric), emerging technologies (oil lamp, new boilers, desalination equipment, storage of wind energy, co-generation), developments and perspectives in the transport sector (example of Renault, new technologies for hybrid propulsion, bio-refineries, reduction of fuel consumption, hybrid aircraft, and heat management in railways) and in the building sector (new standards and applications, new building materials). A last article outlines the threat that climate can be for profitability and the taking of the carbon risk into account by the insurance and financial sectors


    Marian MIHAILA


    Full Text Available International law, taken by globalization, helps emerge “private actors at an international level” by generating “a removal from territories of problems and solutions”. The question of NGO accessing international jurisdictions is situated at this intersection, which is a dangerous one for jurists. The ways of national laws intersect, in fact, with those of international law. More over, private international law, more specifically, the private judicial nature of NGOs that enter into contact with public international law, an intersection that will imprint a plural-disciplinary character that marks this study. Thus, we must follow this rocky road and try a private approach of a question disputed by public law, which is also a part of international law. The risks of maladroitness are numerous, but must be assumed according to their importance and of the rarity of clarification attempts. NGOs, legal persons from private law exercising their activities in international context contain, in fact, elements of foreign origin that result in specific problems of international law. And if “international law can not be the domain of perfect solutions” it can allow however the adoption of others which, that can seem less perfect to some, will possess the aptitude of “creating the laws of a state”. Thus, only by allying public international law to private law, the question of NGOs access to international jurisdictions can receive an answer.

  12. The natural gas industry in Portugal

    This article makes a synthesis of the evolution of the natural gas sector in Portugal since the end of the 1990's. The aim of the energy policy of Portugal was the creation of a liberalized energy market capable to ensure the security of the energy supplies and to encourage the energy efficiency in order to reduce the environmental impact. The success of the introduction of natural gas in Portugal perfectly fulfills these goals. Since 1997, the natural gas consumption has increased significantly. The start-up of the methane terminal of Sines allows the diversification of the supply sources and contributes to the growth of the offer. The opening of the market is under development. It will allow the main consumers to select their supplier among those present on the Portuguese market. GALP company should keep its leader position and its daughter company 'Gas du Portugal' should reach 300 MW of power generation capacities by 2005 with the development of multi-energy services. The creation of an Iberian energy market between Spain and Portugal should speed up in 2004 leading to deep modifications in the energy sector of southern Europe. (J.S.)

  17. Occurrence of persistent organic pollutants in sediments and biota from Portugal versus European incidence: A critical overview.

    Ribeiro, Cláudia; Ribeiro, Ana Rita; Tiritan, Maria Elizabeth


    Persistent organic pollutants (POPs) are widespread compounds, such as organohalogenated compounds, polycyclic aromatic hydrocarbons (PAHs) and pesticides, which can be found in all types of environmental compartments. Their presence in the aquatic environment is a worldwide problem, with emphasis on sediments which act as depository and consequently as a source of hydrophobic, recalcitrant and harmful compounds. Besides, these pollutants might affect the reproduction and mortality of living organisms, diverging in their potential to bioaccumulate in tissues. The present paper aims to review the occurrence of POPs in sediments and biota from the coastal, estuarine and river areas of Portugal. The list of the studied compounds comprises organohalogenated compounds, PAHs, organometallic compounds, pesticides, sterols, fatty acids and pharmaceutical compounds. The contamination of sediments by various pollutants is presented, such as PAHs up to 7,350 ng g(-1) found in Sado estuary and polychlorinated biphenyls up to 62.2 ng g(-1) in the case of sediments collected in Ria de Aveiro. The occurrence of these persistent toxic substances in sediments demonstrates aquatic contamination from agricultural, industrial and urban discharges and the concern about the potential risks to aquatic organisms, wildlife and humans. In fact, several classes of POPs have also been found in biota, such as polychlorinated biphenyls up to 810.9 ng g(-1) in sentinel fish from the Douro River estuary and pesticides in bivalves from the Sado River estuary. The importance of further systematic research on sediments and biota is here highlighted to compare the contamination of these two reservoirs; to assess their spatial and temporal variation; and to determine other classes of POPs that were not investigated yet (e.g., industrial compounds, estrogens and many classes of pharmaceuticals).

  2. Research on virtual actor action editing and movement control

    Wenhu QIN; Yuhui WU; Zhengxu ZHAO


    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.

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

    Grondman, Ivo; Vaandrager, Maarten; Buşoniu, Lucian; Babuska, Robert; Schuitema, Erik


    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.

    Laments the narcissism that the author sees in too many contemporary approaches to acting and directing. Argues that actors must focus on the world outside themselves, where the play and the audience most need them to be. (SR)

  6. Physical Education and sports: sportive institutions and their actors

    Osvaldo Omar Ron


    Full Text Available The work exposed here seeks to display, as a synthesis, the general characteristics and some conclusions of the investigation project "Physical Education and sports: sportive institutions through actors' perspective", developed between 2003 and 2005. It is through it that we sought to recognize the ideas and concepts that coexist in everyday institutional life, by recovering the voice of sport institutions' actors - parents, leaders, trainers and teachers, practising and players-, and also by analyzing speeches and practices; those institutions' distinguishing forms of organization; the ways that diverse actors relate and the social forms acting on them. We investigated sport institutions with the purpose of tracking the senses and meaning that actors grant them, their organization and dynamics, the reasons for their behaviour, the principles and logics that shape them. We also analyzed the joints that link them to external macroinstitutions, their autonomy or dependency with regard to the latter, and their incidence on sport institutions' logics

  8. Actors with Multi-Headed Message Receive Patterns

    Sulzmann, Martin; Lam, Edmund Soon Lee; Van Weert, Peter

    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...... 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 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...

  9. CAM within a field force of countervailing powers: The case of Portugal.

    Almeida, Joana; Gabe, Jonathan


    This paper examines the extent to which the position of the medical profession and the state towards complementary and alternative medicine (CAM) practitioners has changed since the late 1990s, taking Portugal as a case study. Using Light's concept of countervailing powers, we consider the alliances, interests, rhetoric and degrees of control between these three actors over time, focussing particularly on the extent to which CAM practitioners have acted as a countervailing force in their relationship with the medical profession and the state. It also brings to the fore the position of supra-state agencies concerning CAM regulation. A critical discourse analysis was conducted on data derived from a systematic search of information dating from the late 1990s up to 2015. Our analysis suggests that CAM has emerged as an active player and a countervailing power in that it has had significant influence on the process of state policy-making. The medical profession, in turn, has moved from rejecting to 'incorporating' CAM, while the state has acted as a 'broker', trying to accommodate the demands and preferences of both actors while simultaneously demonstrating its power and autonomy in shaping health policy. In sum, the history of countermoves of CAM, the medical profession and the state in recasting power relations regarding CAM regulation in Portugal has highlighted the explanatory value of Light's countervailing power theory and the need to move away from a professional dominance and corporatist approach, in which CAM has simply been seen as subjugated to the power of the medical profession and the state.

  10. A Convergent Online Single Time Scale Actor Critic Algorithm

    Di Castro, D.; Meir, R.


    Actor-Critic based approaches were among the first to address reinforcement learning in a general setting. Recently, these algorithms have gained renewed interest due to their generality, good convergence properties, and possible biological relevance. In this paper, we introduce an online temporal difference based actor-critic algorithm which is proved to converge to a neighborhood of a local maximum of the average reward. Linear function approximation is used by the critic in order estimate ...

  12. Using Actor Network Theory to Understand Information Security Management

    Hedström, Karin; Dhillon, Gurpreet; Karlsson, Fredrik


    This paper presents an Actor Network Theory (ANT) analysis of a computer hack at a large university. Computer hacks are usually addressed through technical means thus ensuring that perpetrators are unable to exploit system vulnerabilities. We however argue that a computer hack is a result of different events in a heterogeneous network embodying human and non-human actors. Hence a secure organizational environment is one that is characterized by 'stability' and 'social order', which is a resul...

  19. La prueba PISA: una mirada alternativa desde la Teoría del Actor-Red

    Paola Paredes Suzarte


    Full Text Available En el marco de la proliferación de las evaluaciones estandarizadas, inscritas en lo que ha sido conceptualizado por la literatura como políticas de accountability o de rendición de cuentas, se ofrece por medio de este artículo una línea de pensamiento y discusión alternativa sobre la prueba PISA. Utilizando como enfoque la Teoría del Actor-Red (TAR de Bruno Latour, se presentan ejercicios de traslación epistémica de la prueba PISA desde un modelo de pensamiento positivista moderno, a uno materialista pragmático en el que se privilegia una descripción constructivista y analítica de los componentes que la constituyen. En base al seguimiento y análisis de noticias sobre la prueba PISA desplegadas en diarios electrónicos en Chile y Argentina, más la revisión de fuentes secundarias, se exponen algunas de las controversias suscitadas en torno a la evaluación y se discute sobre su posible impacto en nuestras percepciones sobre educación y calidad. También se problematiza el carácter neutral y objetivo de la prueba, y se levanta la pregunta acerca de su posible agencia en la cristalización de las relaciones de centro-periferia entre países que, en el marco del enfoque de la TAR, tiene sentido explorar. 

  20. Muslim Slaves and Freedmen in Medieval Portugal

    Soyer, François


    Full Text Available The study of slavery in medieval Portugal has focused almost exclusively on the status and fate of the sub-Saharan Africans who started to arrive in the kingdom from 1441 onwards. The work of A. C. de C. M Saunders, A Social History of Black Slaves and Freedmen in Portugal 1441-1555 (Cambridge University Press, 1982 has been particularly important in this respect. In stark contrast to this, the fate of the substantial number of Muslim slaves who lived and worked in Portugal during the medieval period has to a large extent been overlooked. Using documentary evidence obtained from the national Portuguese archives, this article proposes to analyse in detail the origins of these slaves, their economic and social role and the laws that were promulgated to control them and their owners. The status of freedmen and manumission practices are also closely studied.

    El estudio de la esclavitud en el Portugal medieval ha sido dominado por estudios sobre los esclavos oriundos del África subsahariana que comenzaron a ser importados en aquel reino desde 1441. La obra de A. C. de C. M. Saunders, A Social History of Black Slaves and Freedmen in Portugal 1441-1555 (Cambridge University Press, 1982 ha sido particularmente importante a este respecto. En contraste con esta situación, se sabe relativamente poco de los esclavos musulmanes en el reino medieval de Portugal. Utilizando nuevas fuentes documentales del archivo nacional portugués, este artículo se propone examinar los orígenes de estos esclavos musulmanes y su posición económica y social en el Portugal del medievo, así como las leyes reales que fueron promulgadas para controlar a los esclavos y a sus dueños. La posición social de los libertos y las prácticas de manumisión serán también estudiadas.

  1. Neo-Lamarckism in Portugal

    Almaça, Carlos


    Full Text Available

    Darwinism was championed in Portugal by the University and progressionist political parties from the 1860's on. Neo-Darwinism was neglected in its proper time and so the acceptance of the inheritance of acquired characters continued over the first decades of the 20th century. Men of medical education who were professors of Biology at the University of Oporto supported neo-Lamarckian theories in early 20th century. The first one has been Américo Pires de Lima (1886-1966, professor of Botany, whose doctoral dissertation sustaining early Darwinism and neo-Lamarckism was presented in 1912. This thesis, as well as a few neo-Lamarckian publications with antropological significance, are commented and discussed in the present paper.

    El Darwinismo fue defendido en Portugal en la Universidad y por los partidos políticos progresistas durante la década de los años 60 del siglo XIX. El neo-darwinismo fue ignorado en su tiempo y así continuó la aceptación de la herencia de los caracteres adquiridos a lo largo de las primeras décadas del siglo XX. Los profesores de biolog

    Actor-Critic based approaches were among the first to address reinforcement learning in a general setting. Recently, these algorithms have gained renewed interest due to their generality, good convergence properties, and possible biological relevance. In this paper, we introduce an online temporal difference based actor-critic algorithm which is proved to converge to a neighborhood of a local maximum of the average reward. Linear function approximation is used by the critic in order estimate the value function, and the temporal difference signal, which is passed from the critic to the actor. The main distinguishing feature of the present convergence proof is that both the actor and the critic operate on a similar time scale, while in most current convergence proofs they are required to have very different time scales in order to converge. Moreover, the same temporal difference signal is used to update the parameters of both the actor and the critic. A limitation of the proposed approach, compared to results a...

  4. Transnational corporations as 'keystone actors' in marine ecosystems.

    Henrik Österblom

    Full Text Available Keystone species have a disproportionate influence on the structure and function of ecosystems. Here we analyze whether a keystone-like pattern can be observed in the relationship between transnational corporations and marine ecosystems globally. We show how thirteen corporations control 11-16% of the global marine catch (9-13 million tons and 19-40% of the largest and most valuable stocks, including species that play important roles in their respective ecosystem. They dominate all segments of seafood production, operate through an extensive global network of subsidiaries and are profoundly involved in fisheries and aquaculture decision-making. Based on our findings, we define these companies as keystone actors of the Anthropocene. The phenomenon of keystone actors represents an increasingly important feature of the human-dominated world. Sustainable leadership by keystone actors could result in cascading effects throughout the entire seafood industry and enable a critical transition towards improved management of marine living resources and ecosystems.

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

    Qubbaj, Murad R.; Muneepeerakul, Rachata


    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.

  9. In Portugal, the energy revolution is underway

    As at the beginning of 2013, 70 per cent of the electricity consumed in Portugal had a renewable origin, this article outlines that this result is based on a strong-willed policy. In fact, Portugal entered the energy transition in 2001 with its '4E program' (energy efficiency and endogenous energies) which aimed at reaching 60 per cent of renewable energies in electricity consumption by 2020. This program was based on a strong development of wind and hydraulic energy. Moreover, the country developed its own capacities for the manufacturing of wind turbines. On another hand, other renewable energies (notably solar energy) seem a bit late although several projects are underway. As far as hydraulic energy, a dam project is a matter of controversy

  8. Essays on actor models in exchange networks and social dilemmas

    Assen, Marcus Adrianus Leonardus Maria van


    A central problem in economics and sociology is that of explaining or predicting phenomena at the macro-level. One possible mode of explanation or prediction of macro-level phenomena entails examining processes internal to the system that involve actors at the micro-level. In this dissertation complexities were added to the model of the actor on the micro-level in order to better predict and understand two macro-level phenomena that receive a lot of attention in social science research in gen...

  11. Population diversity of Theileria annulata in Portugal.

    Gomes, Jacinto; Salgueiro, Patrícia; Inácio, João; Amaro, Ana; Pinto, João; Tait, Andy; Shiels, Brian; Pereira da Fonseca, Isabel; Santos-Gomes, Gabriela; Weir, William


    The tick-borne protozoan parasite Theileria annulata causes tropical theileriosis, a severe disease of cattle that occurs across the Mediterranean littoral, the Middle East and Southern Asia. In the Mediterranean region, the disease has long been perceived as being a constraint to livestock production in North Africa and Turkey but was believed to have minimal impact in Southern European countries. It has recently been demonstrated that in Southern Portugal the prevalence of T. annulata is approximately 30%. While the population genetics of the parasite and the multiplicity of infection in the bovine host have been studied in a number of countries, no information is currently available on the composition of the parasite population in Southern Europe or its relationship to populations in bordering regions. A parasite genotyping system, based on micro- and mini-satellite amplification, was used to perform genetic analysis of T. annulata populations from T. annulata infected cattle in twelve farms in Southern Portugal. A diversity of genotypes and a high multiplicity of infection were found, suggesting that the parasite possesses a panmictic population in this region. In comparison with genotypes found in Tunisia and Turkey, parasites from Portugal form a genetically distinct group and show lower genetic diversity. PMID:27109468

  12. Municipal solid waste disposal in Portugal

    In recent years municipal solid waste (MSW) disposal has been one of the most important environmental problems for all of the Portuguese regions. The basic principles of MSW management in Portugal are: (1) prevention or reduction, (2) reuse, (3) recovery (e.g., recycling, incineration with heat recovery), and (4) polluter-pay principle. A brief history of legislative trends in waste management is provided herein as background for current waste management and recycling activities. The paper also presents and discusses the municipal solid waste management in Portugal and is based primarily on a national inquiry carried out in 2003 and directed to the MSW management entities. Additionally, the MSW responsibility and management structure in Portugal is presented, together with the present situation of production, collection, recycling, treatment and elimination of MSW. Results showed that 96% of MSW was collected mixed (4% was separately collected) and that 68% was disposed of in landfill, 21% was incinerated at waste-to-energy plants, 8% was treated at organic waste recovery plants and 3% was delivered to sorting. The average generation rate of MSW was 1.32 kg/capita/day

  13. New Actors in Health Financing: Implications for a Donor Darling

    Denis Drechsler; Felix Zimmermann


    With concern about how to finance the Millennium Development Goals (MDGs) widespread, recent donor pledges to raise aid volumes are welcome. However, aid alone will not suffice – bringing in new actors and sources of development finance will be essential. In many developing countries, this is already happening, creating new opportunities and challenges for their governments and donors....

  18. VR/IS Lab Virtual Actor research overview

    Shawver, D.M.; Stansfield, S.


    This overview presents current research at Sandia National Laboratories in the Virtual Reality and Intelligent Simulation Lab. Into an existing distributed VR environment which we have been developing, and which provides shared immersion for multiple users, we are adding virtual actor support. The virtual actor support we are adding to this environment is intended to provide semi-autonomous actors, with oversight and high-level guiding control by a director/user, and to allow the overall action to be driven by a scenario. We present an overview of the environment into which our virtual actors will be added in Section 3, and discuss the direction of the Virtual Actor research itself in Section 4. We will briefly review related work in Section 2. First however we need to place the research in the context of what motivates it. The motivation for our construction of this environment, and the line of research associated with it, is based on a long-term program of providing support, through simulation, for situational training, by which we mean a type of training in which students learn to handle multiple situations or scenarios. In these situations, the student may encounter events ranging from the routine occurance to the rare emergency. Indeed, the appeal of such training systems is that they could allow the student to experience and develop effective responses for situations they would otherwise have no opportunity to practice, until they happened to encounter an actual occurance. Examples of the type of students for this kind of training would be security forces or emergency response forces. An example of the type of training scenario we would like to support is given in Section 4.2.

  19. The Mousterian complex in Portugal

    João Luís CARDOSO


    Full Text Available ABSTRACT: Considering the available data, the Mousterian period is the only techno-complex from the Middle Paleolithic identified and characterized in Portugal. However, some of the sites referred in this work should be simply attributed to the Middle Paleolithic due to the lack of detailed elements. The site of Vale do Forno 8 probably represents the transition between the final Upper Paleolithic and the early Middle Paleolithic.The open-air sites such as the ones in the outskirts of Lisbon and on the left margin of the Tagus estuary, where vestiges are extremely abundant and the permanence for long periods correspond to sites of residential character.None of these sites were subject to extensive excavations in order to confirm this type of settlement and further knowledge of the social organization of the inhabited spaces. Other open-air sites located in fluvial terraces present smaller areas of occupation and were probably related to game activities, maybe seasonal in nature. This was the case of Santo Antão do Tojal, were elephants and horses were eventually captured, of Foz do Enxarrique were red deer was almost exclusive and of Vilas Ruivas, were faunal remains were not preserved but remains of wind-breaks or hunting blind structures were found associated with fireplaces and post-holes. Fireplaces were also found in Gruta da Buraca Escura and on the open-air site of Santa Cita.Caves such as Gruta da Oliveira and the Gruta Nova da Columbeira show long stratigraphic sequences and prolonged settlements, of residential type, though a few other caves also show temporary settlements related to game activities or the exploitation of geological resources. In most cases, there is an alternance of the cave occupation by humans and large carnivores. Food subsistence of humans was non-specialized, capturing large, mid and also small preys such as the rabbit, an abundant endemic species. The terrestrial turtle was also captured, especially in Gruta

  5. The future of nuclear power in Portugal

    Full text: 1. Introduction. The paper will be an update of the paper entitled 'Nuclear technology and energy in Portugal' prepared for the IAEA Workshop: 'Steps for Conducting Nuclear Power Plant Technology Assessments' which took place in Vienna on 17 - 20 November 2008. 2. Update on the ITN. The ITN continues to be the main institution in the country dealing with nuclear applications. A probable visit of the author to this institution before the conference will enable to supply more information, particularly on its readiness to develop capabilities to enacting the legal regulatory framework for nuclear power generation and the capacity to implement it. 3. Energy Policy, Supply and Demand in Portugal. An Update on the Energy Policy, Supply and Demand in Portugal will be supplied with the most recent figures extracted from the International Energy Agency in Paris and national sources. The present Administration continues to place emphasis on renewable forms of energy, without considering the nuclear option in the energy mix. The prospects for nuclear energy in Portugal have been affected by the ongoing economic crisis. This crisis has particularly affected the economy with has a low per capita GDP by European standards and is still too dependent on export oriented industries with a weak technology base. Entrepreneurs and government have became more concerned with short term measures , consequently the interest in nuclear energy , a long term endeavor, has taken a long step back. While the plans to pursue renewable energies continued unabated, the import of electric energy and oil and gas has increased in the recent two years. New licenses have been recently awarded for eight gas power plants. Prospects on whether the increase of energy demand will continue in the face of the ongoing economic downturn will be analyzed in the paper. Elections planned during 2009 for the European parliament, local bodies and the national parliament are not expect to change the

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

    Ana Isabel Xavier


    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

  7. Balancing influence between actors in healthcare decision making

    Babad Yair M


    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

  8. Public Investment and Budgetary Consolidation in Portugal

    Alfredo M. Pereira; Maria de Fátima Pinho


    In this paper we find that public investment in durable goods has a positive effect on long-term economic performance in Portugal. We also find that these positive effects are not strong enough for public investment to pay for itself in the form of future tax revenues. Therefore, cuts in public investment in durable goods, although costly in terms of long-term economic performance seem to be an effective way of alleviating pressure on the public budget. It is important to note, however, that ...

    International Monetary Fund


    The three year Fund-supported program that expired at end-June 2014 succeeded in stabilizing Portugal’s economy and restoring access to sovereign debt markets. Following the deep downturn of 2011–12, the economy has expanded in six of the last seven quarters, albeit at a moderate pace. The cumulative fiscal consolidation over the past three years has been substantial, and the current account is now in surplus. Regained policy credibility and benign market conditions have facilitated the r...

  17. Current status of nucleonic gauges in Portugal

    The nucleonic gauges are largely used in Portugal industry, despite the fact that design and manufacturing of prototypes of nucleonic gauges is rather limited. The modernization of some industrial sectors (cement, paper and civil engineering) has enhanced applications of nucleonic gauges and has created local capability but new legislation tends to restrict further spread of them. The Institute of Nuclear Technology is the only applied research institution developing nucleonic gauges for moisture, thickness and density, and elemental analysis, as well as providing assistance in calibration, safe operation and maintenance of them.

  20. Semantics for Communicating Actors with Interdependent Real-Time Deadlines

    Knoll, Istvan; Ravn, Anders Peter; Skou, Arne


    Models of embedded systems with communicating actors and deadlines offer abstraction and encapsulation of related functionality, but their behavior is complex. Verification is therefore difficult and requires a combination of simulation, model checking and testing tools. In order to rely 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...... 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....

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

    Stensdal, Iselin


    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)

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

    Lisa-Britt Fischer


    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.

  8. An Actor-Critic Algorithm for Sequence Prediction

    Bahdanau, Dzmitry; Brakel, Philemon; Xu, Kelvin; Goyal, Anirudh; Lowe, Ryan; Pineau, Joelle; Courville, Aaron; Bengio, Yoshua


    We present an approach to training neural networks to generate sequences using actor-critic methods from reinforcement learning (RL). Current log-likelihood training methods are limited by the discrepancy between their training and testing modes, as models must generate tokens conditioned on their previous guesses rather than the ground-truth tokens. We address this problem by introducing a \\textit{critic} network that is trained to predict the value of an output token, given the policy of an...

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

    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

  10. The European Union as a Comprehensive Police Actor

    Stephen Anthony Rozée


    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.
