    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.

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

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

    2014-10-01

    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.

  5. Early diagenesis and clay mineral adsorption as driving factors of metal pollution in sediments: the case of Aveiro Lagoon (Portugal).

    This work aims to define the factors driving the accumulation of metals in the sediment of the lagoon of Aveiro (Portugal). The role of initial diagenetic processes in controlling trace metal retention in surface sediment is traced by mineralogy, magnetic susceptibility and geochemical analyses. Although several studies have focused on the metal distribution in this polihaline and anthropized coastal lagoon, most of them have been solely focused on the total metal concentrations. This study instead represents the first attempt to evaluate in a vast area of the Aveiro Lagoon the role of biogeochemical processes in metal availability and distribution in three extracted phases: exchangeable cations adsorbed by clay and elements co-precipitated with carbonates (S1), organic matter (S2) and amorphous Mn hydroxides (S3). According to the sediment guideline values, the sediment is polluted by, for instance, As and Hg in the inner area of the Murtosa Channel, Pb in the Espinheiro Channel, Aveiro City canals and Aveiro Harbour, and Zn in the northern area of the Ovar Channel. These sites are located near the source areas of pollutants and have the highest total available concentrations in each extracted phase. The total available concentrations of all toxic metals are however associated, firstly, with the production of amorphous Mn hydroxides in most of the areas and, secondly, with adsorption by organic compounds. The interplay of the different processes implies that not all of the sites near pollution sources have polluted surface sediment. The accumulation of metals depends on not only the pollution source but also the changing in the redox state of the sediments that may cause alterations in the sediment retention or releasing of redox-sensitive metals. Results of this work suggest that the biogeochemical processes may play a significant role in the increase of the pollutants in the sediment of the Aveiro Lagoon.

    Full Text Available Fish assemblages of Ria de Aveiro coastal lagoon (Northwest Portugal were studied from February 2012 and January 2013. Sampling were monthly conducted with a traditional beach-seine net (“chincha” at 9 sites. Multivariate approach were used in order to analyse the spatial and temporal variation in fish community. A total of 58,201 fishes, weighting 249,540 g, were identified, representing 37 taxa and 21 families. Four taxa (Atherina spp., Dicentrarchus labrax, Liza spp., and Sardina pilchardus were responsible for 94.7% and 85.4% of the total abundance, in number and weight. There were significant differences in fish community, in terms of fish number and weight, between sites and between months (ANOSIM, p<0.01. A total of 12 species appeared as characteristics of one of more sampling sites either in terms of number and weight. In both cases, D. labrax, Liza spp. and Atherina spp. were typical throughout the study area. Other species, such as Spondyliosoma cantharus appeared as typical only in the part of the lagoon more influenced by marine waters, whereas Anguilla anguilla was typical of the inner area. A total of 11 (in number or 13 (in weight species appeared as typical of at least one month of the year. Liza spp. and Atherina spp. were typical all the year round for number and weight data. In both cases, D. labrax, Diplodus spp. and S. pilchardus, appeared as a typical from spring to autumn. The number of typical species varied with the season, being maximum in May and minimum in winter. Finally, results of this work were discussed in comparison to previous studies.

    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.

    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

    The use of some fish parasites as bioindicators of heavy metal pollution has been demonstrated as particularly adequate due to their capacity of bioconcentration. This study evaluated the effect of Proteocephalus macrocephalus on the accumulation of trace elements in the edible fish, Anguilla anguilla, in a contaminated area in Portugal (Ria de Aveiro). Also, the model P. macrocephalus/A. anguilla was assessed as a bioindicator system in the presence of the highly prevalent nematode Anguillicola crassus. Samples (kidney, liver, muscle, A. crassus and P. macrocephalus) of 20 eels harbouring A. crassus and another 20 harbouring both A. crassus and P. macrocephalus were selected for element analysis by ICP-MS. The highest concentrations of Cr, Ni and Zn were detected in P. macrocephalus. However, there was a higher liver and muscle Cr concentration in eels not infected by P. macrocephalus. Also, the nematode A. crassus presented higher Cr concentrations in those eels harbouring P. macrocephalus. Results suggest that P. macrocephalus individuals accumulate Cr and Ni while levels of Cr in eel livers and Ni levels in eel kidney are reduced. The system P. macrocephalus/A. anguilla yielded bioaccumulation factors for Cr, Ni, Pb and Zn, whereas bioaccumulation of Cu, Cr and Pb in A. crassus varied according to eel co-infection with P. macrocephalus, thus emphasising the possible role of cestode infection in metal metabolization/storage processes in host tissues. Results suggest that heavy metal pollution in Ria de Aveiro has been decreasing although it is still higher than in other contaminated areas in Europe. Nevertheless, eel consumption in Ria de Aveiro represents no risk for humans although they may represent a real contamination risk for wildlife. The system P. macrocephalus/A. anguilla is proposed as another promising bioindicator system to evaluate environmental Cr, Ni, Pb and Zn exposure in estuarine areas where both species co-occur.

    Full Text Available Cada país tiene sus casos historiográficos y Portugal no escapa a la regla. Tenemos muchos casos, muchas dudas, muchas historias. El dia 3 de septiembre de 1758 quedará para siempre envuelto en el misterio, lo que no impide que procuremos hacer la mayor luz posible sobre el tema del atentado contra el rey D. José, junto a la quinta de Belém. El atentado originó un proceso sumarísimo que en casi cuatro meses liquidó las Casas de Távora, Atouguia y Aveiro, así como a la Compañía de Jesús, con las monstruosas ejecuciones en el patíbulo de Belém del 13 de enero de 1759. Los inventarios y el secuestro de bienes ejecutados por orden de la Junta da Inconfidência, pueden servir tanto para medir la grandeza de las Casas, como también su situación social y financiera. Por estos inventarios se evidencia que estas Casas, que eran socialmente de las más consideradas en Portugal en el siglo XVIII, estaban bastante endeudadas. A mediados del siglo XVIII, la clase emergente de hombres de negocios y de prestamistas era, de hecho, la poseedora de los grandes activos de éstos y de otros Grandes de Portugal ya que los mismos servían de garantía a los créditos concedidos. Sin embargo, la aristocracia, profundamente endogámica, no se permitía ninguna contaminación con las clases adineradas, pero sin título. Este hecho nos sirve de punto de partida para llegar a conclusiones tangenciales de coyuntura para la década de los 50 del siglo XVIII, así como también de estructura, válidas éstas para todo el período pombalino, por lo que respecta a los Grandes de Portugal.Each country has its own histograph cases and Portugal is no exception.

    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.

    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.

    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

    The aim of this study was to investigate the influence of monospecific colonization of sediment stands by Spartina maritima or Halimione portulacoides on benthic prokaryote assemblages in a salt marsh located in Ria de Aveiro (Portugal). The distribution of Bacteria, Archaea and sulfate-reducing bacteria (SRB) in sediments with monospecific plant stands and in unvegetated sediments was characterized by Fluorescence In Situ Hybridization (FISH). Total prokaryote abundance (0.4 × 109-1.7 × 109 cells gdw-1) was highest in sediments from the surface layer. The domain Bacteria comprised approximately 40% of total prokaryote communities with the highest percentages occurring in the surface layer. Archaeal cells corresponded to an average of 25% of total prokaryote population, with higher abundance in the vegetation banks, and displaying homogeneous vertical distribution. The relative abundance of SRB represented approximately 3% of total 4', 6-diamidino-2-phenylindole dihydrochloride (DAPI) stained cells at unvegetated sediment and H. portulacoides stand and 7% at S. maritima stand. Headspace solid-phase microextraction (HS-SPME) combined with Comprehensive Two-Dimensional Gas Chromatography-Time-of-Flight Mass Spectrometry (GC × GC-ToFMS) was used to analyse the volatile and semi-volatile fraction of root exudates. A total of 171 compounds were identified and Principal Component Analysis showed a clear separation between the chemical composition (volatile and semi-volatile organic compounds) of the exudates of the two plants. The patterns of vertical distribution and differences in the proportion of SRB and Archaea in the prokaryote communities developing in sediments colonized by Spartina maritima or Halimione portulacoides suggest the existence of plant-specific interactions between halophyte vegetation and estuarine sediment bacteria in Ria de Aveiro salt marshes, exerted via sediment lithology and root-derived exudates.

    Primary producers represent an important pathway for mercury incorporation in aquatic food webs. With eutrophication processes occurring worldwide, macroalgae may represent a substantial pool of mercury, as a result of its high growth rate and capacity to bind trace metals. The main aim of this work was to evaluate the response of the macroalgae to a human-induced environmental mercury gradient in a temperate coastal lagoon, by assessing the total and organic mercury contamination levels of t...

    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

    High-accuracy Doppler shift measurements and high-precision spectroscopy are primary techniques in the search for exo-planets. Further extremely interesting applications include the analysis of QSO absorption lines to determine the variability of physical constants and the analysis of the isotopic ratios of absorption lines both in stars and in QSOs, and the determination of stellar oscillations through radial velocity measurements. Since the use of high-precision/resolution spectroscopy is closely connected to the ability to collect a large number of photons, the scientific domains using this technique benefit tremendously from the use of 8-meter class telescopes and will fully exploit the tremendous gain provided by future Extremely Large Telescopes (ELTs). IR high-resolution spectroscopy should soon approach the same accuracy regime achieved in the optical range. This volume comprehensively covers the astrophysical and technical aspects of high-precision spectroscopy with an outlook to future developments,...

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

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

    2010-01-01

    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...

    Different characteristics of Spartina maritima found in two distinct salt marshes located in different estuaries were analysed through interpretation of their local hydrodynamic patterns, as well as the impact of sea level rise on physical processes and consequently on plant dynamics and salt marshes stability. These salt marshes are situated in two of the most important Portuguese coastal systems, Tagus estuary (Rosário salt marsh) and Ria de Aveiro lagoon (Barra salt marsh), which are dominated by physical processes that induce strong tidal currents. They were monitored during one year and plant and sediment samples of S. maritima were collected quarterly in order to determine the vegetation coverage, above and belowground biomass, organic matter and sediment moisture. Residual circulation, tidal asymmetry and tidal dissipation were determined from numerical modelling results of the MOHID 2D model that was applied to each coastal system, considering the actual sea level and a sea level rise (SLR) scenario. Results suggest that the different characteristics found for Spartina maritima in the Rosário and the Barra salt marshes may be related with the diverse hydrodynamic conditions identified for each salt marsh. Consequently, the exploration of SLR scenario predictions indicates how these salt marshes could evolve in the future, showing that the important changes in these hydrodynamic parameters under climate change context might induce significant modifications in the salt marshes dynamics and stability. SLR scenario could lead to changes in nutrients and sediments patterns around the salt marshes and thus vegetation coverage percentage would be affected. Additionally, as a consequence of flood duration increase, sediment moisture will increase causing a stress condition to plants. Hence, the ratio below/aboveground biomass might increase, becoming critical to plants survival under conditions of accelerated sea level rise. Accordingly, both SLR and expected

    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

    Full Text Available Different from existing range-free algorithms in wireless sensor networks (WSN, a cooperative localization algorithm based on coverage optimization of actors (CLCOA for wireless sensor and actor networks (WSAN is proposed. It uses mobile actors instead of anchors in WSN. Firstly, the area of the unknown node is determined through the movement of positioning actors. Then this area decreases through iteration. When localization accuracy is satisfied, the centroid of this area is calculated and treated as the coordinate of the unknown node. Free actors adjust their positions through virtual force while locating actors work. Accordingly, actors’ coverage is optimized. Via simulation, it is proven that CLCOA has high locating accuracy with RSSI error and GPS error, and the introduction of virtual force improves actors’ coverage and locating speed

    1993-09-01

    Perceivers who observe social behaviors may form impressions not only of actors' traits but also of people as targets and of interpersonal relationships. In Study 1, Ss read about 4 individuals' behaviors under instructions to form actor-, target-, and relationship-based impressions. Ss then read additional behavioral information that they later tried to recall. Ss accurately perceived actor, target, and relationship effects in the presented information, and they better recalled subsequent behaviors that were consistent with all 3 types of impressions. In Study 2, Ss thought of 4 people they knew and judged how much each liked the other 3. These ratings revealed actor, target, and relationship effects as well as individual and dyadic reciprocity. Perceivers can form relatively accurate impressions of people as actors and as targets and accurate impressions of relationships between people, and these impressions influence memory for further behaviors.

    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.

  11. Off-Policy Actor-Critic

    CERN Document Server

    Degris, Thomas; Sutton, Richard S

    2012-01-01

    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...

  12. Empathy and attribution: turning observers into actors.

    Science.gov (United States)

    Regan, D T; Totten, J

    1975-11-01

    A laboratory experiment was conducted to test Jones and Nisbett's information-processing explanation of the often-observed tendency for individuals (actors) to provide relatively more situational and less dispositional causal attributions for their behavior than those provided by observers of the same behavior. According to this explanation, aspects of the situation are phenomenologically more salient for actors, whereas characteristics of the actor and his behavior are more salient for observers. To test this explanation, the phenomenological perspective of observers are altered without making available any additional information. Subjects watched a videotape of a get-acquainted conversation after instructions either to observe a target conversant or to empathize with her. As predicted, taking the perspective of the target through empathy resulted in attributions that were relatively more situational and less dispositional than attributions provided by standard observers. The results support Jones and Nisbett's information-processing explanation of actor-observer attributional differences, and shed additional light on the process of empathy.

  16. The moral problem of worse actors

    Directory of Open Access Journals (Sweden)

    Scott Wisor

    2014-05-01

    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.

    2009-08-01

    Full Text Available Actor-network theory and the analysis of technoscience developed by Javier Echeverría (2003 have many features in common, but they also diverge in a number of points. While the analysis of technoscience amounts to the attempt of classifying and characterizing the modalities of contemporary scientific and technological practices, the set of methodological tools of actor-network theory brings to the forefront the disorder hidden behind the ordered image of both contemporary and past technoscience. However, actor-network theory may be useful to describe the complex networks woven by research centres, institutions, universities, and companies, and their products in terms of natural and social order. In this paper, we characterize actor-network theory as well as technoscience and we identify how both, in spite of their differences, might benefit each other.La teoría del actor-red y el análisis de la tecnociencia desarrollado por Javier Echeverría (2003 presentan múltiples puntos comunes, pero también importantes divergencias. Mientras que el análisis de la tecnociencia responde al intento filosófico de clasificar y caracterizar las modalidades de práctica científico-tecnológica contemporánea, el conjunto de herramientas metodológicas de la teoría del actor-red trae al primer plano el desorden oculto tras la ordenada apariencia de la tecnociencia, la contemporánea y la de épocas pasadas. Sin embargo, la teoría del actor-red se muestra útil para describir las complejas redes tejidas por centros de investigación, instituciones, universidades y empresas, y los productos resultantes de las mismas en términos de orden natural y social. En este trabajo caracterizamos someramente tanto la teoría del actorred como la tecnociencia, para identificar de qué modo ambas, pese a sus diferencias, pueden beneficiarse mutuamente.

  19. A Method for Studying Social Actors

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available So little agreement exists on what constitutes sociology that it seems impossible to de?ne its speci?c methods. We can however proceed through a series of eliminations. Light has been shed on many types of social behavior as economic studies have taken more interest in issues of social strati?cation and mobility or in consumer behavior, and as they increasingly incorporate elaborate quantitative analysis into this type of data. Correlations between social statuses and social behavior tell us about the logic of the system, yet not about that of the actors. Hence, we must imagine other methods in order to reach the actor as an autonomous being, as an agent of transformation of his environment and of his own situation, as a creator of imaginary worlds, as capable of referring to absolute values or of being involved in love relations.

    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...

  6. Geology and religion in Portugal

    Science.gov (United States)

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

    2013-01-01

    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.

    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.

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.

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.

    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.

    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)

Beyond the definition of social actor, the assumption of the existence of key actors implies conceptual and practical limitations, as it depends of each specific situation. Everyone could be a key actor under differential roles in the generation of environmental politics. As an alternative, the term "noteworthy actors" is used and a brief review of them in Latin America is presented. The relevant question should address the social scenarios from where these actors can express themselves. A preliminary distinction of scenarios is presented, in which old and new social movements could be integrated and relationships of articulation and equivalence could be established.

  3. 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

  6. NGO - PRIVATE ACTORS AT AN INTERNATIONAL LEVEL

    Directory of Open Access Journals (Sweden)

    2011-12-01

    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.

  7. A solution for actors' viewpoints representation with collaborative product development

    2007-01-01

    As product complexity and marketing competition increase, a collaborative product development is necessary for companies which develop high quality products in short lead-times. To support product actors from different fields, disciplines, and locations, wishing to exchange and share information, the representation of the actors' viewpoints is the underlying requirement of the collaborative product development. The actors' viewpoints approach was designed to provide an organisational framework following the actors' perspectives in the collaboration, and their relationships, could be explicitly gathered and formatted. The approach acknowledges the inevitability of multiple integration of product information as different views, promotes gathering of actors' interests, and encourages retrieved adequate information while providing support for integration through PLM and/or SCM collaboration. In this paper, a solution for neutral viewpoints representation is proposed. The product, process, and organisation informa...

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

    Science.gov (United States)

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

    2016-01-01

    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).

    1991-02-01

    Full Text Available In Portugal fish farming has expanded very rapidly in the last decade, with trout, mullet, cuttlefish, seabream, eel, salmon and prawns being intensively reared in artificial ponds. A questionnaire was sent to all known fish farmers to assess the effect of predation, especially by otters; no compensation scheme exists in Portugal. This paper discusses the results of this exercise. It is suggested that fish farmers need to look beyond economic and technological aspects of aquaculture and consider the wider environmental impact of their activities.

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

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

    Science.gov (United States)

    Almeida, Joana; Gabe, Jonathan

    2016-04-01

    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.

    2007-12-01

    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.

    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.

    Wenhu QIN; Yuhui WU; Zhengxu ZHAO

    2008-01-01

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

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

    2012-06-01

    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.

    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

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

    To assess prevalence of interpersonal violence among a mixed gender sample of immigrants in Portugal, describing the type of violence and associated factors. A cross-sectional study was conducted between October 2008 and May 2009, evaluating a sample of 702 immigrants residing in the Lisbon region. Information was obtained by trained interviewers using a structured questionnaire. Overall, 15.1 % (15.5 % females and 14.7 % males; p = 0.844) of the immigrants reported to be victims of at least one episode of violence during the last year, regardless of which type of violence was involved. The prevalence of intimate-partner violence was 4.1 %, and it was significantly higher among women than men (7.1 % vs. 0.9 %, respectively, p Portugal, with different gender patterns regarding the perpetrators and settings of abuse.

    2013-04-01

    Several studies demonstrate that wildfires in Portugal present high temporal and spatial variability as well as cluster behavior (Pereira et al., 2005, 2011). This study aims to contribute to the characterization of the fire regime in Portugal with the multivariate statistical analysis of the time series of number of fires and area burned in Portugal during the 1980 - 2009 period. The data used in the analysis is an extended version of the Rural Fire Portuguese Database (PRFD) (Pereira et al, 2011), provided by the National Forest Authority (Autoridade Florestal Nacional, AFN), the Portuguese Forest Service, which includes information for more than 500,000 fire records. There are many multiple advanced techniques for examining the relationships among multiple time series at the same time (e.g., canonical correlation analysis, principal components analysis, factor analysis, path analysis, multiple analyses of variance, clustering systems). This study compares and discusses the results obtained with these different techniques.

    The relatively recent phenomenon of migration into Portugal is broken down into three components: foreign immigrants, return of emigrants, and repatriation of those from the old African colonies in Angola and Mozambique. Changes in the flow of migrants since 1960 are noted, and the economic and social situation of the various groups of immigrants is examined. Changes in public policies aimed at addressing migration-related issues are also discussed. (SUMMARY IN ENG AND SPA)

    2009-01-01

    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...

    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

    Full Text Available The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity. All the terrestrial isopods from caves of mainland Portugal, including data from the literature and new material, are listed, revealing new biodiversity patterns. Twenty-seven species, belonging to 15 genera and six families, are known, of which 16 species are considered to be exclusively from subterranean ecosystems, i.e., troglobionts. Trichoniscidae is the most diverse family. Seven species in the family Trichoniscidae and one species in the family Styloniscidae are described as new (all with Reboleira & Taiti as authors: Trichoniscoides bellesi sp. nov. from the Montejunto Massif; T. sicoensis sp. nov. from the Sicó Massif; Metatrichoniscoides salirensis sp. nov. from the typhonic valley of Caldas da Rainha; Troglonethes olissipoensis sp. nov. from the Lisbon Peninsula; T. arrabidaensis sp. nov. from the Arrábida Massif; Miktoniscus longispina sp. nov. from the Sicó Massif and Cesaredas Plateau; Moserius inexpectatus sp. nov. from the Estremenho Massif; and Cordioniscus lusitanicus sp. nov. from Alentejo and Algarve, the southernmost provinces of Portugal. The subgenus Trogleluma Vandel, 1946 (Armadillidiidae is raised to genus level. In this geographic region terrestrial isopods are the richest group of cave-adapted animals.

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

    Directory of Open Access Journals (Sweden)

    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.

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

    Directory of Open Access Journals (Sweden)

    Guillaume Devin

    2010-12-01

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

    João Luís CARDOSO

    2009-12-01

    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

    Neurocysticercosis (NCC) is the most common cause of acquired epilepsy in resource-poor countries. We report the case of a 24-year-old woman born and residing in Guinea-Bissau, who was transferred to Portugal two months after the onset of a possible meningitis (fever, headache, seizures, and coma) that did not respond to antibiotic treatment. The diagnosis of NCC was confirmed by MR imaging, which showed multiple lesions compatible with cysticercus, and by polymerase chain reaction (PCR) of the cerebrospinal fluid. After 28 days on albendazole and dexamethasone without improvement, she was started on praziquantel, which she completed in six weeks with progressive recovery.

    2014-09-01

    In sum, this paper examines the core determinants of lottery sales in Portugal. With panel data analysis covering 18 Portuguese districts and 5 years, this study explains the variations in a district's per-capita lottery sales in terms of key theoretical hypotheses such as per capita district income, age, education index, gender and religion. This paper concludes that the richer Portuguese districts spend more than the poorer districts and there is an inverted-U relationship between lottery sales and per capita income. The paper also concludes that married Catholic citizens spend more on lottery products than others and that the level of education returns a negative effect on lottery spending.

    2013-05-01

    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

  18. Balancing influence between actors in healthcare decision making

    2011-04-01

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

    This radar image of Lisbon, Portugal illustrates the different land use patterns that are present in coastal Portugal. Lisbon, the national capital, lies on the north bank of the Rio Tejo where the river enters the Atlantic Ocean. The city center appears as the bright area in the center of the image. The green area west of the city center is a large city park called the Parque Florestal de Monsanto. The Lisbon Airport is visible east of the city. The Rio Tejo forms a large bay just east of the city. Many agricultural fields are visible as a patchwork pattern east of the bay. Suburban housing can be seen on the southern bank of the river. Spanning the river is the Ponte 25 de Abril, a large suspension bridge similar in architecture to San Francisco's Golden Gate Bridge. The image was acquired on April 19, 1994 and is centered at 38.8 degrees north latitude, 9.2 degrees west longitude. North is towards the upper right. The image is 50 kilometers by 30 kilometers (31 miles by 19 miles). The colors in this image represent the following radar channels and polarizations: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted and vertically received; and blue is C-band, horizontally transmitted and vertically received.

    2009-12-01

    Full Text Available In Portugal we are assisting, since the nineties, to the reform of all public accounting, having as main innovations the utilization of double entry system and the obligatoryness to implement three accounting systems: budget accounting, patrimonial and cost accounting. In the systems of patrimonial and cost accounting, it will be used the accrual systems. The publication of the first Public Accounting Plan (POCP in 1997 identifies the change from a traditional public accounting, which main objective was the execution and budgetary control to a modern public accounting with economical, financial and patrimonial information that serves as basis to the decision making and to the evaluation of public entities concerning the efficient, effective utilization and economy of the public resources, contributing, this way, to the implementation of the New Public Management. The objective of this work has two perspectives: to describe and analyze the situation in Portugal concerning the public accounting reform and to present some results consequent to twelve years of implementation.

  1. CHINESE ENTREPRENEURIAL ACTIVITY IN PORTUGAL: TRADITIONAL ETHNIC STRATEGIES?

    Directory of Open Access Journals (Sweden)

    Catarina Reis Oliveira

    2010-12-01

    Full Text Available In Portugal in recent decades, just like in other welcoming countries, immigrants have reached levels of entrepreneurial activity that are higher than those of autochthonous citizens. However, a deeper analysis of the official data shows that not all immigrant groups have the same tendency to become entrepreneurs. In this respect, the Chinese stand out as being the group with the highest ratio of entrepreneurial activity in Portugal, despite the fact that their migration is a relatively recent phenomenon. What factors can explain the Chinese community’s disproportionate rate of entrepreneurial initiative? Do they possess any particular resources that make them more enterprising than the autochthonous population, or than other groups of immigrants? Does the context of Portugal hamper certain opportunities or in some way limit their economic integration into the job market? Do we find similar business strategies among other Chinese entrepreneurs residing in welcoming societies apart from that of Portugal? Why did Chinese business initiative grow at such an exceptional rate in Portugal in the late 1990s? By seeking answers to these questions, this article attempts to examine Chinese business strategies in Portugal, as well as their exceptional success rate in comparison with other entrepreneurial immigrants. To that end, the author has analysed the data gathered in a survey carried out on 309 Chinese entrepreneurs resident in Portugal (see Oliveira, 2005.

Therefore an analysis and comparison of relevant concepts that capture the key generative features of actor bonds in both socially constructed networks and socially constructed markets is undertaken. These concepts include the "milieu" of project marketing (Cova et al., 1996......Demand in many industrial buying situations, e.g. project purchases or procurement related to virtual organizations, is discontinuous. In situations of discontinuity, networks are often more of an ad hos informational and social nature, as strong activity and resource links are not present......) and the institutional concept of the "field". Finally this paper introduces the concept of "social capital" (Bourdieu, 1983) and discusses whether it can be used to conceptualize the dynamic features of actor bonds in situations of discontinuity....

    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....

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

    Energy Technology Data Exchange (ETDEWEB)

    Stensdal, Iselin

    2012-11-01

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

    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...

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

    International Nuclear Information System (INIS)

    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

  14. The European Union as a Comprehensive Police Actor

    Directory of Open Access Journals (Sweden)

    Stephen Anthony Rozée

    2011-12-01

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

  15. Environmental actors and European integration: Attitudes towards further integration

    Energy Technology Data Exchange (ETDEWEB)

    Dahl, A.

    1994-12-31

    This report asks to what extent environmental actors in the EU are positively or negatively inclined to further integration of environmental policy in the EU, and why. The main objective in the EU`s fifth environmental action programme is to integrate environmental concerns into other policy areas. In this study the concept of integration is used to describe various forms of cooperation between states, from independent nation states (inter-governmentalism) at one end of the scale to a supranational authority at the other. What kind of EU cooperation do environmental actors want? Do they believe that further integration of environmental policy in the EU will promote environmental interests and facilitate the integration of environmental concern into other policy areas? Or do they believe that further integration of environmental policy in the EU will reduce the possibilities of developing an ambitious environmental policy in Europe? The empirical material for the study consists of interviews with representatives of political parties and environmental organizations at both the national and the international level. The study concentrates on four arguments called (1) The ``transboundary`` argument, referring to the transboundary character of environmental problems, (2) The single market argument, focusing on the internal market and use of economic instruments in EU environmental policy, (3) The institutional argument, referring to the effectiveness of EU institutions in solving environmental problems and (4) The political influence argument, which focuses on political influence of environmental actors in the development of EU environmental policy. 29 refs., 8 tabs.

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

    Science.gov (United States)

    Elder-Vass, Dave

    2008-09-01

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

    2009-06-01

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

    Full Text Available From 1564 to 1565, Clusius (1526-1609 travelled to the Iberican Peninsula as the tutor of the young heir of the Függers. This journey, which lasted nearly a year, took the two men to the most important cities in the Peninsula. If strolling through the Portuguese countryside demonstrated the peculiarities of the local flora to the botanist, the decreed visit to Lisbon offered many surprising experiences. The encounter with the work recently arrived from the Orient —Colóquios dos Simples e Drogas he Cousas Mediçinais da Índia, by Garcia de Orta (Goa, 1563— awakened his interest. The present article weaves together considerations on the multiple impacts that the botanist’s voyage to Portugal caused in European science of the time.

    International Nuclear Information System (INIS)

    This study reports the occupational radiation doses for external exposure received in 1999 by the radiation workers monitored by the Radiological Protection and Nuclear Safety Department (DPRSN) in Portugal. Occupational exposures arise from conventional industry, research laboratories, the health or medical sector, and mining. There are no nuclear power plants in the country. There are two dosimetry systems running simultaneously at DPRSN, one based on film dosimetry and the other on thermoluminescence dosimetry (TLD). In 1999, 8400 persons were monitored, 3100 with film and 5300 with TLD and the data presented in this report were obtained by using both technologies. The annual mean effective doses received from external radiation in the different fields of activity and the distribution of the annual effective dose by dose intervals are presented. The collective annual dose by field of activity is estimated and the contribution to the total annual collective dose is determined. (author)

    Full Text Available España y Portugal son dos países que comparten mucho en el terreno de la historia, la cultura y la geografía. Sin embargo, esa misma proximidad se ha convertido muchas veces en el principal obstáculo para que cooperen entre sí.Desde la perspectiva portuguesa, la proximidad española se ha visto permanentemente como una amenaza a la independencia de Portugal. Desde el punto de vista de España, la cercanía de Portugal ha debilitado su consideración como país extranjero y ha acentuado un sentido de comunidad no siempre bien recibido por los portugueses. De modo que Portugal siempre ha querido diferenciarse y España ha respondido siempre aproximándose. Esta es la raíz del malentendido.Este cruce de percepciones distintas sobre el valor de proximidad, da lugar a todo tipo de equívocos, pues el deseo de diferenciación de uno puede entenderse como enemistad por el otro y, a la inversa, el de aproximación del segundo como invasión por el primero. Ejemplo de esto es lo que ocurre con la palabra iberismo, una palabra que se escribe igual en ambas lenguas pero que puede significar cosas opuestas, esto es, que puede ser un falso amigo. Así en las dos lenguas iberismo señala el ideal de una integración de ambos países, pero en portugués esto implica la subordinación de la soberanía portuguesa a la española y puede vincularse a la idea de traición; mientras que en español tiene una carga política mucho menor y puede apuntar a la simple simpatía por Portugal.En este artículo quiero mostrar cómo la proximidad de España y Portugal ha sido un obstáculo en las relaciones exteriores entre los dos países peninsulares, cuya comunicación ha sido distorsionada por los falsos amigos hasta el punto de convertirse, ellos mismos, en falsos amigos.

    In my research I examine the situation of women from Eastern Europe who migrate alone to Portugal. Many had to leave behind their families and children. This Thesis explores the women's decisions for leaving their home countries, and looks at the experiences and challenges they face in Portugal. The impact of the women's often undocumented legal status and the precarious work conditions is explained. Central to the Thesis is the migrants' possibilities for agency and the meaning of migration ...

    Climatic variability from the beginning of regular meteorological observations is now acknowledged. However, climate change prior to 1900 is far from being well known in Portugal, except for the 1675-1800 period in Southern Portugal. An interdisciplinary team is working in the frame of the KLIMHIST PROJECT ("Reconstruction and model simulations of past climate in Portugal using documentary and early instrumental sources, 17th-19th century)", since May 2012. The main objectives of the project are: (i) to contribute to the creation of a long-term history of climate in Portugal by producing databases of documentary evidence and of instrumental data since 1645, a period of natural climate variability that includes the Maunder Minimum and the Dalton Minimum; (ii) to search systematically for the first simultaneous documentary and instrumental data in order to calibrate the series; (iii) to analyse simulated multi-decadal trends over Portugal generated by climate models; (iv) to compare results with those obtained from dendroclimatology and from geothermal studies regarding Portugal and (v) to study extreme events of the past, their impacts and the vulnerability of societies to weather during the last 350 years, and compare them with current analogues. With these tasks, we expect to help completing the spatial coverage of past European climate, as the data gap over SW Europe is often mentioned. As the team members come from four different Universities in Portugal (Évora, Lisbon, Oporto and UTAD), we expect to obtain a good spatial representation of documentary evidence. Teams are now progressing in data search activities in archives. An Access database frame was constructed. Some 18th century extreme events have been and are being studied (Barbara storm, Dec.1739, among others). The first workshop took place in Lisbon (October 2012): Prof Brázdil and Dr. Domínguez-Castro (two of our consultants) were keynote speakers. Key-words: Climate reconstruction, Documentary

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

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

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

    Introdução: A satisfação com a profissão médica tem sido apontada como um fator essencial para a qualidade assistencial, o bemestar dos doentes e a estabilidade dos sistemas de saúde. Estudos recentes têm vindo a enfatizar um crescente descontentamento dos médicos, principalmente como consequência das alterações das relações laborais.Objetivos: Avaliar a perceção dos médicos de formação específica em Portugal, sobre as expectativas e grau de satisfação com a profissão, especialidade e local de formação; razões da insatisfação e intenção de emigrar.Material e Métodos: Estudo transversal. A colheita de dados foi efetuada entre Maio e Agosto de 2014 através de um Inquérito online sobre a âÄúSatisfação com a EspecialidadeâÄù.Resultados: De uma população total de 5788 médicos, foram obtidas 804 respostas (12,25% do total de médicos internos). Desta amostra, 77% das respostas correspondem a internos dos três primeiros anos de formação. Verificou-se que 90% dos médicos se encontram satisfeitos com a especialidade, tendo-se encontrado também níveis elevados de satisfação com a profissão (85%) e local de formação (86%). Por outro lado, constatou-se que estes diminuíam com a progressão ao longo dos anos de internato. A avaliação global sobre o panorama da prática médica foi negativa e 65% dos médicos responderam que consideram emigrar após conclusão do internato.Conclusão: Os médicos internos em Portugal apresentam níveis positivos de satisfação com a sua profissão. No entanto, a sua opinião sobre o panorama da Medicina e os resultados relativos à intenção de emigrar alertam para a necessidade de tomada de medidas para inverter este cenário.

    Full Text Available São representadas cartograficamente as unidades geomorfológicas identificadas para os 89015 km2 do território de Portugal Continental. A delimitação das unidades teve por base a análise dos padrões da textura fornecida por imagens SRTM, com revisão e adaptação posterior à altimetria e à geologia, para os quais foram usadas bases cartográficas digitais. Foram considerados três níveis taxionómicos que permitem descrever e caracterizar áreas homogéneas do ponto de vista geomorfológico. As três unidades de 1º nível baseiam-se nas unidades morfostruturais clássicas consideradas para a Península Ibérica. As dez unidades de 2º nível constituem, na sua maioria, divisões clássicas do relevo de Portugal Continental, agora agrupadas de acordo com a metodologia adoptada e designadas como unidades morfosculturais. As 56 unidades de 3º nível, ou subunidades morfosculturais, foram individualizadas com base nos padrões de relevo identificados nas imagens SRTM e na observação de campo e adquiriram uma designação baseada essencialmente nas geoformas que as individualizam e na toponímia local. As unidades geomorfológicas identificadas são descritas através de características do relevo, dissecação fluvial, estruturas, tipo de drenagem e base geológica, bem como de parâmetros numéricos gerados de forma automática, como classes de altitude e de declividade. Pretende-se que o mapa elaborado possa contribuir para a gestão territorial, em especial na tomada de decisões em conservação da natureza.

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

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

  12. Ship Finds and Their Management as Actor Network

    Science.gov (United States)

    Tuddenham, David Berg

    2012-12-01

    Ship finds in Norwegian waters that are more than 100 years old came under the jurisdiction of the Cultural Heritage Management (CHM) in 1963, when section 12a of the Norwegian Cultural Heritage Act was implemented. As a consequence, a functional division between land and sea was created where management objects receive different values depending on whether or not they belong to a ship. The objective of this paper is to review Norwegian CHM underwater policy, and discuss the creation of a new management object and its borders with the introduction of a section on ship finds specifically focusing on Actor Network Theory. It is argued that the understanding of the ship find and its belongings can not be understood as something based on inherent qualities to the management object. Instead this paper proposes to comprehend the ship find as a phenomenon held together within a heterogeneous network.

    Ding, Xu Chu; Lahijanian, Morteza; Paschalidis, Ioannis Ch; Belta, Calin A

    2012-01-01

    In this paper, we consider the problem of deploying a robot from a specification given as a temporal logic statement about some properties satisfied by the regions of a large, partitioned environment. We assume that the robot has noisy sensors and actuators and model its motion through the regions of the environment as a Markov Decision Process (MDP). The robot control problem becomes finding the control policy maximizing the probability of satisfying the temporal logic task on the MDP. For a large environment, obtaining transition probabilities for each state-action pair, as well as solving the necessary optimization problem for the optimal policy are usually not computationally feasible. To address these issues, we propose an approximate dynamic programming framework based on a least-square temporal difference learning method of the actor-critic type. This framework operates on sample paths of the robot and optimizes a randomized control policy with respect to a small set of parameters. The transition proba...

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

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

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

  2. Census Model Transition: Contributions to its Implementation in Portugal

    2016-03-01

    Full Text Available Given the high cost and complexity of traditional censuses, some countries have started to change the census process. Following this trend, Portugal is also evaluating a new census model as an alternative to an exhaustive collection of all statistical units. The main motivations for the implementation of this census model transition in Portugal are related to the decrease in statistical burden on citizens, improvements in the frequency of outputs, and the reduction of collection costs associated with census operations. This article seeks to systematise and critically review all alternatives to the traditional census methodologies, presenting their advantages and disadvantages and the countries that use them. As a result of the comparison, we conclude that the methods that best meet these objectives are those that use administrative data, either in whole or in part. We also present and discuss the results of an inventory and evaluation of administrative registers in Portugal with the potential to produce statistical census information.

  3. Contribution of natural gas for sustainable development in Portugal

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Portugal has strongly limited domestic energy resources, since imports almost 90% of its energy needs and its energy production is totally from renewable energy sources. The addition of natural gas to the Portuguese energy mix in 1997 helped to diversify Portugal’s energy sources and is a contribution to the mitigation of environmental problems. In 1997 also ceased the production and use of domestic coal. In fact, Portugal is working to reduce the growth in energy use and CO2 emissions, in order to follow the Kyoto Protocol. This measure can be linked to environmental sustainability policies, creating the opportunity for new business to appear. Natural gas, in some applications, can substitute the electricity, implying a decrease in price. Security of gas supply is an important issue, since Portugal depends mainly on a single supplier. This paper aims at analysing the emerging gas market, (threats and opportunities, its evolution andcomparison with other OECD countries.

  7. The Feminization of the Judiciary in Portugal: Dilemmas and Paradoxes

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available In recent decades, a significant transformation in the legal professions has been its increasing feminization. However, if in other countries we can find relevant studies on this subject, the gender variable is rarely taken into account in Portugal, except through intuitive and non-scientific processes and discourses that often produce bias and where female judges and public prosecutors have no voice. This article aims to contribute to filling in this empirical lacuna and, based on a survey of the Portuguese population and on interviews with judges and public prosecutors in Portugal, to analyse the existing views on the feminization of justice and female judging.

    During the bovine spongiform encephalopathy (BSE) epidemic, Portugal was the third most affected country. As a result of a successful national eradication plan, the number of BSE affected animals has been progressively declining in Portugal with no cases identified in 2013. However, within the scope of this active surveillance scheme, we have identified the first H-type BSE case born after the introduction of the reinforced ban in fallen stock. Here, we report the phenotypic features of this case and the analysis of the protein coding sequence of prnp as well as the prnp promoter and intron 1 insertion-deletions.

    2016-04-01

    In the framework of the EU-FP7 project RECARE (www.recare-project.eu) and, in particular, its WP6, the University of Aveiro partner has recently started testing two measures against the soil threat of post-fire erosion by water in an area in north-central Portugal, close to Coimbra that burnt during the summer of 2015. These measures - mulching with forest slash residues and contour ploughing - had been selected by the local and external stakeholders involved in the project, through two subsequent stakeholder workshops. While contour ploughing has still not taken place, the mulching was already carried out, using residues from eucalypt plantations as the burnt areas was dominated by eucalypt plantations, and applying them in a homogeneous fashion at two contrasting application rates, i.e. a "standard" rate of approximately 10 Mg ha-1 and a "reduced" rate of about 3 Mg ha-1. The standard rate was selected for having proved effective in reducing post-fire runoff and erosion in previous field studies in the region (Prats et al., 2012, 2014, 2015a), while the reduced rate had been found to be nearly as effective as the standard rate in a recent study in the hydraulic laboratory of the University of Coimbra (Prats et al., 2015b). Unlike the referred prior studies, however, the present study will also assess the impacts of mulching on two other soil threats - i.e. decline in soil organic matter and in soil biodiversity - and, ultimately, will compare the two measures in terms of their consequences for soil-based ecosystem services, using the framework being developed by RECARE (Schwilch et al. in Stolte et al., 2016). The proposed presentation will show the first results on the effects of the two mulch application rates on post-fire runoff as well as the associated losses of sediments, organic matter/C and nutrients (N, P), and on selected indicators of soil biological activity and diversity.

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

    International Nuclear Information System (INIS)

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

  13. Direct SW aerosol radiative forcing over Portugal

    Full Text Available In this work, the evaluation of the aerosol radiative forcing at the top of the atmosphere as well as at the surface over the south of Portugal is made, particularly in the regions of Évora (38°34' N, 7°54' W and of Cabo da Roca (38°46' N, 9°38' W, during years 2004 and 2005.

    The radiative transfer calculations, using the radiative transfer code Second Simulation of the Satellite Signal in the Solar Spectrum (6S, combine ground-based measurements, from Aerosol Robotic NETwork (AERONET, and satellite measurements, from MODerate Imaging Spectroradiometer (MODIS, to estimate the direct SW aerosol radiative forcing. The method developed to retrieve the surface spectral reflectance is also presented, based on ground-based measurements (AERONET of the aerosol optical properties combined with the satellite-measured radiances (MODIS.

    The instantaneous direct SW aerosol radiative forcing values obtained at the top of the atmosphere are, in the majority of the cases, negative, indicating a tendency for cooling the Earth at the top of the atmosphere. For Desert Dust aerosols, over the Évora land region, the average forcing efficiency is estimated to be −25 Wm−2/AOT0.55 whereas for the Cabo da Roca area, the average forcing efficiency is −46 Wm−2/AOT0.55. In the presence of Forest Fire aerosols, both from short and long distances, the average value of forcing efficiency at the top of the atmosphere over Cabo da Roca is found to be −28 Wm−2/AOT0.55 and, over Évora, −27 Wm−2/AOT0.55. For specific situations, discussed in this work, the average surface direct SW aerosol radiative forcing efficiency due to the Desert Dust aerosols, in Évora region, is −66 Wm−2/AOT0.55, whereas in Cabo da Roca region, the corresponding average value is −38 Wm−2/AOT0.55

    Full Text Available The estimation of radiative forcing due to desert dust and forest fires aerosols is a very important issue since these particles are very efficient at scattering and absorbing both short and longwave radiation. In this work, the evaluation of the aerosol radiative forcing at the top of the atmosphere over the south of Portugal is made, particularly in the regions of Évora and of Cabo da Roca.

    The radiative transfer calculations combine ground-based and satellite measurements, to estimate the top of the atmosphere direct SW aerosol radiative forcing. The method developed to retrieve the surface spectral reflectance is also presented, based on ground-based measurements of the aerosol optical properties combined with the satellite-measured radiances.

    The aerosol direct radiative effect is shown to be very sensitive to the underlying surface, since different surface spectral reflectance values may originate different forcing values. The results obtained also illustrate the importance of considering the actual aerosol properties, in this case measured by ground-based instrumentation, particularly the aerosol single scattering albedo, because different aerosol single scattering albedo values can flip the sign of the direct SW aerosol radiative forcing.

    The instantaneous direct SW aerosol radiative forcing values obtained at the top of the atmosphere are, in the majority of the cases, negative, indicating a tendency for cooling the Earth. For Desert Dust aerosols, over Évora land region, the average forcing efficiency is estimated to be −25 W/m2/AOT0.55 whereas for Cabo da Roca area, the average forcing efficiency is −46 W/m2/AOT0.55. In the presence of Forest Fire aerosols, over Cabo da Roca region, the average value of forcing efficiency is −28 W/m2/AOT0.55 and over Évora region an average value of −33 W/m2/AOT0.55 is found.

  17. Optimal Placement of Actors in WSANs Based on Imposed Delay Constraints

    Directory of Open Access Journals (Sweden)

    Chunxi Yang

    2014-01-01

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

    2006-10-01

    Full Text Available Abstract Background Listeriosis is a rare disease caused by the bacterium Listeria monocytogenes, the normal vehicle of which is food. The disease, which is largely confined to its risk groups of pregnant women, the elderly and immunocompromised individuals, has increased in incidence in recent years. In Portugal, listeriosis is not a notifiable infection and available data are scarce. The objective of this work was to collate the available information concerning listeriosis in Portugal by compiling a retrospective study of cases recorded over a decade. Methods Requests for case data on clinically confirmed listeriosis, recorded over the previous decade, were replied to by 23 hospitals and a National Institute of Health delegation. Results 35 cases of listeriosis were identified for the period between 1994 and 2003 inclusive, the mortality rate being greater than 17%. According to the data collected in this study for the year 2003, the incidence of this disease in Portugal was at least 1.4 cases per million inhabitants in that year. Conclusion The study demonstrates, for the first time in the widely available literature, that despite their being no cases of listeriosis in Portugal recorded in official reports, the threat of L. monocytogenes to public health is of a similar dimension to that in other countries.

    Full Text Available Automatic recovering node failure in wireless sensor actor network to identify the cutvertex and to meet to the node failure. The network consists of many nodes that are constructed into a tree structure. Once the tree has been constructed the shortest path is found by the Aodv protocol.If a node failure occurs in the shortest path then the cut-vertex could be recovered and the data can be securely passed on to the destination in an alternative route obtained from the routing table. Heartbeat messages acknowledge the node failure. The feasible path is not found by the protocol, and then the network is divided into two or many parts. The MLeDir algorithm is used to identify the network failure and disjoint block of the network. The disjoint block is identified by the MLeDir algorithm and to rectify the disjoint block of failure network nodes. MLeDir algorithm is moving only the respective nodes from source to destination.

  1. Actors of the hydrogen sector in France; Les acteurs de l'hydrogene en France

    2010-07-01

    This document proposes brief presentations (web site address, activities) of actors operating in the hydrogen sector in France. 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

  3. Occupational radiation doses in Portugal from 1994 to 1998

    International Nuclear Information System (INIS)

    This work reports on the occupational radiation doses for external radiation received in 1994-1998 by the radiation workers monitored by the Radiological Protection and Nuclear Safety Department (DPRSN) in Portugal. Individual monitoring for external radiation is carried out in Portugal by DPRSN since the 60s, and the workers are monitored on a monthly or quarterly bases. In 1995 DPRSN monitored approximately 8000 people and was the only laboratory carrying out this sort of activity in Portugal. In 1998 the number of monitored people increased to nearly 8500 from 860 facilities, which leads us to state that the results shown in this work are well representative of the universe of radiation workers in Portugal. Until 1996, the dose measurement procedure was based only on film dosimetry and the results reported for the 1994-1995 period were obtained with this methodology. Since 1996, thermoluminescent dosimetry (TLD) was gradually introduced and since then an effort has been made to transfer the monitored workers from film to TLD. In 1998, both film and TLD dosimetry systems were running simultaneously, with average numbers of 4500 workers monitored with film dosimetry, while 4000 were monitored with TLD. The data presented from 1996 to 1998 were obtained with both methodologies. This work reports the annual mean effective doses received from external radiation, for the monitored and exposed workers in the different fields of activity, namely, industry, research laboratories, health and mining. The distribution of the annual effective dose by dose intervals is also reported. The collective annual dose by field of activity is estimated and the contribution to the total annual collective dose is determined. The collective dose estimates for the period 1994 to 1998 demonstrated that the health sector is the most representative exposed group in Portugal. (author)

  4. Actors or Spectators? Vulnerability and Critical Environmental Law

    Directory of Open Access Journals (Sweden)

    2013-12-01

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

  5. Src: marker or actor of prostate cancer aggressiveness

    Directory of Open Access Journals (Sweden)

    2014-08-01

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

  6. Natural gas supply strategies for European energy market actors

    International Nuclear Information System (INIS)

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

  7. Force-stabilizing synergies in motor tasks involving two actors

    We investigated the ability of two persons to produce force-stabilizing synergies in accurate multi-finger force production tasks under visual feedback on the total force only. The subjects produced a time profile of total force (the sum of two hand forces in one-person tasks and the sum of two subject forces in two-person tasks) consisting of a ramp-up, steady-state, and ramp-down segments; the steady-state segment was interrupted in the middle by a quick force pulse. Analyses of the structure of inter-trial finger force variance, motor equivalence, anticipatory synergy adjustments (ASAs), and the unintentional drift of the sharing pattern were performed. The two-person performance was characterized by a dramatically higher amount of inter-trial variance that did not affect total force, higher finger force deviations that did not affect total force (motor equivalent deviations), shorter ASAs, and larger drift of the sharing pattern. The rate of sharing pattern drift correlated with the initial disparity between the forces produced by the two persons (or two hands). The drift accelerated following the quick force pulse. Our observations show that sensory information on the task-specific performance variable is sufficient for the organization of performance-stabilizing synergies. They suggest, however, that two actors are less likely to follow a single optimization criterion as compared to a single performer. The presence of ASAs in the two-person condition might reflect fidgeting by one or both of the subjects. We discuss the characteristics of the drift in the sharing pattern as reflections of different characteristic times of motion within the sub-spaces that affect and do not affect salient performance variables.

  10. International Political Actorness of the EU: the Dichotomy of Agent and Structure

    Directory of Open Access Journals (Sweden)

    Gnatyuk Nikolay Nikolaevich

    2015-04-01

    Full Text Available Theories of international relations, regional integration and comparative politics have significant difficulties with the classification of the EU as an actor of international politics. At the same time the EU international activities challenge not only the idea of superior role of the state in international relations but also the structure of international system. The article states that conceptualization of international actors should not contrast two levels of analyses – the internal condition of actor and the structure of international system, but treat them as being neutral. Based on suggestions of pluralistic approach, the article argues that primary burden of progress in the classification of the EU as an actor of international politics is due to one way interpretation of “structure and agents problem”. In this regard the constructivist idea of treating actor and structure as mutually constructive may be a useful starting point. Unlike attempts to consider the international activities of the EU as “state like” entity, this approach allows taking into account the EU integrative nature, which is characterized by the presence of individual features of the traditional international actors. Therefore, the concept of international actorness as an alternative to state-centered approaches may offer a theoretical and methodological framework for the understanding of different elements and building-blocks of the “EU as an international actor”. Interaction of variables of internal and external levels composes a harmonized system for evaluating the EU international activity.

  17. Portugal and United States cooperative energy assessment. Volume 3. Reference reports, Part 1

    Energy Technology Data Exchange (ETDEWEB)

    1981-09-01

    Statistical data on energy production and consumption and supporting information were obtained from US Bureau of Mines records supplemented by additional data obtained in Portugal. Geologic descriptions and analysis of known areas and of areas having possible future potential have been prepared by the US Geological Survey. Portugal lacks sufficient indigenous supplies of organic fuels to meet its energy demands, and so must import large quantities of petroleum and coal. Approximately 80% of Portugal's electric energy is produced by hydroelectric stations; thermal stations produce the other 20%. Portugal has produced no crude oil, natural gas, or condensate; no resources or reserves in these categories are listed for Portugal in the 1976 World Energy Conference report. Until the last year or so (1980), no significant onshore petroleum exploration had been done in Portugal since 1963. Production of coal in Portugal has declined steadily to the present annual yield of about 200,000 metric tons. On the basis of estimates in only three coal fields, resources of coal of all ranks in Portugal total at least 76 million (10/sup 6/) metric tons. Uranium is mined near Viseu and Guarda in the northern part of Portugal; the Nisa mine in east-central Portugal will begin producing uranium ore in 1985 after installation of a processing plant. Portugal produced 95 metric tons of uranium oxide (U/sub 3/O/sub 8/) from ore stocks in each year from 1972 through 1974; production is assumed to have continued at the same rate since then. Geothermal energy has not been developed in mainland Portugal; however, hot springs that may have geothermal energy potential are known in the Minho district in the northwest. Geothermal energy resources exist in the Azores and a program of evaluation and exploration with technical assistance from the USGS is presently in progress there.

    Zika virus is an emerging arbovirus transmitted by Aedes sp. mosquitoes like the Dengue and Chikungunya viruses. Zika virus was until recently considered a mild pathogenic mosquito-borne flavivirus with very few reported benign human infections. In 2007, an epidemic in Micronesia initiated the turnover in the epidemiological history of Zika virus and more recently, the potential association with congenital microcephaly cases in Brazil 2015, still under investigation, led the World Health Organization (WHO) to declare a Public Health Emergency of International Concern on February 1, 2016. Here, we present the clinical and laboratory aspects related to the first four imported human cases of Zika virus in Portugal from Brazil, and alert, regarding the high level of traveling between Portugal and Brazil, and the ongoing expansion of this virus in the Americas, for the threat for Zika virus introduction in Europe and the possible introduction to Madeira Island where Aedes aegypti is present.

    Full Text Available The allis shad (Alosa alosa and the twaite shad (Alosa fallax are anadromous migratory species, which are threatened not only in Portugal but also in most of their geographic area of distribution. Overfishing and illegal fishing, pollution, physical barriers and river-bed changes seem to be the main reasons for the populations gradual decline. The progressive reduction in the numbers of anadromous fish registered in the last decades in some Portuguese river basins requires urgent action, namely the implementation of measures to promote the recovery of those populations. The current status of shads populations in Portugal is discussed, and the distribution along the main Portuguese watersheds and major threats to these species are presented, as well.

    2016-01-01

    Dirofilaria repens causes subcutaneous infection in dogs and cats, and is the main agent of human dirofilariosis in Europe. Detection of D. repens is described in a dog from Portugal, a finding that simultaneously represents the first presumable case of autochthonous infection with the parasite in any animal host species in the country. A mixed D. repens/Dirofilaria immitis infection (20:1 ratio) was found, with an overall density of 1267 microfilariae per millilitre of blood. Morphological features, including morphometry, and acid phosphatase histochemical staining confirmed identity of the two filarioids. Distribution of D. repens in Portugal should be further assessed at the population level both in vertebrate hosts and in vectors. Due to the zoonotic potential of the parasite, preventive measures such as the administration of microfilaricides and insect repellents should be put into practice to protect animals and public health.

  11. Photovoltaic energy mini-generation: Future perspectives for Portugal

    International Nuclear Information System (INIS)

    This paper evaluates the benefits of developing the mini-generation PV market in Portugal. It presents the legal framework and current status of the Portuguese PV electricity sector, and compares the country to other European nations: France, Germany, Greece, Italy, Spain and the United Kingdom. A model that combines PVGIS with a self-developed financial tool is used to assess the feasibility of a 150 kW mini-generation system using five different technologies: fixed mount, single-axis tracking, double-axis tracking, low concentration and medium concentration (MCPV). The profitability of the mini-generation systems in the seven countries studied is calculated and compared. According to this analysis, MCPV and, of the conventional technologies, the single-axis tracking systems are the most profitable technologies. Despite the attractiveness of the current Portuguese feed-in tariffs and of the abundant solar resource, investors are discouraged and the country's PV market is far from mature. Specific mini-generation regulations should focus on a fast and transparent licensing procedure and should promote the access to financing. This would attract new investments, which would result in the growth of the PV electricity produced, and would help Portugal to meet its European Union Renewable Energy targets. - Highlights: → This work promotes the development of a mini-generation PV market in Portugal. → The Portuguese current status and legal framework is compared to other EU countries. → The profitability of 5 different PV technologies is compared for 7 European countries. → The Portuguese growth potential for PV energy is still big. → Portugal, due to its radiation levels, presents excellent investment opportunities.

    Toxoplasmosis is a worldwide zoonosis. However, data from Portugal are limited and a considerable part of the literature is in Portuguese. Currently, the rate of congenital infection in Portugal is unknown, and almost nothing is known of sequelae of congenital toxoplasmosis. There is no recent general population-based serological survey of Toxoplasma gondii in humans in Portugal. In addition, there is little information on genetic characteristics of T. gondii in animals and humans. In the present paper, we review prevalence, clinical spectrum and epidemiology of T. gondii in humans and animals in Portugal. This knowledge should be useful to biologists, public health workers, physicians and veterinarians.

    Full Text Available A year ago, Portugal celebrated the twenty-fifth anniversary of the so-called Revolution of the Carnations, which marked the beginning of an unstoppable process of democratization and the ensuing full incorporation of Portugal into the institutionalized international community. The Portugal’s opting for orderly decolonialization and full integration into the world of international law has twice brought it a non-permanent seat on the United Nations Security Council and also the Presidency of the UN General Assembly. In the area of security and defense, Portugal began an unprecedented change of course. Its traditional alliance with NATO has been strengthened by new strategic concepts and by its incorporation into new peacekeeping and international security programs in organizations such as the UN, the Western European Union, the OSCE, and even withinthe framework of the European Union where it participates quite actively in accordance with its level in relation to the other members. Also analyzed are the process of incorporation into Community institutions and its direct, precise participation in the evolution they have followed in recent years, with it now being fully integrated into all the areas of regional integration from the "eurozone” to the Schengen framework. The article also points out the gains this very rational choice has brought. Finally, the changes that have come about in bilateral relations with Spain are analyzed.

    Full Text Available This article discusses the issue of taxation of insolvent companies in Portugal, particularly regarding the Portuguese tax on revenue of legal entities (IRC. For this purpose, first, some considerations on the legal framework of insolvent companies are woven and, second, their tax regime is analyzed. Then, a brief review of the main studies that, in the international context, analyze and debate major issues derived from the tax regime of insolvent companies is conducted, particularly in Brazil, Spain, United States, and Italy. Finally, there are the results of an empirical study conducted in Portugal, in 2013, which evaluates and compares the opinions of insolvency administrators (IA, the tax and customs authority (TA, and court magistrates (CM, in order to contribute to a better solution concerning business taxation under this regime. Respondents (IA, TA, CM demonstrate objective thinking about the fact they believe it is very important that the Portuguese Code of Insolvency and Business Recovery (CIRE and the Portuguese Code of Tax on Revenue of Legal Entities (CIRC are modified, now to make clear whether the settlement of property ownership of an insolvent estate is liable to the IRC, then to assign a chapter specifically devoted to the subject of taxation on insolvency in Portugal.

An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or “running ear” and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.Keywords: otitis media, costs, societal burden, Portugal

  11. Two-factor theory, the actor-critic model, and conditioned avoidance.

    Maia, Tiago V

    2010-02-01

    Two-factor theory (Mowrer, 1947, 1951, 1956) remains one of the most influential theories of avoidance, but it is at odds with empirical findings that demonstrate sustained avoidance responding in situations in which the theory predicts that the response should extinguish. This article shows that the well-known actor-critic model seamlessly addresses the problems with two-factor theory, while simultaneously being consistent with the core ideas that underlie that theory. More specifically, the article shows that (1) the actor-critic model bears striking similarities to two-factor theory and explains all of the empirical phenomena that two-factor theory explains, in much the same way, and (2) there are subtle but important differences between the actor-critic model and two-factor theory, which result in the actor-critic model predicting the persistence of avoidance responses that is found empirically.

  15. El entrenamiento como base de la formación actoral

    Directory of Open Access Journals (Sweden)

    Carlos Araque Osorio

    2011-05-01

    Full Text Available The text presents a reflection on the actor’s training and its implications, virtues and contributions to the professional formation of actors. It starts from the experience that the author has assimilated as teacher and director, but mainly as an active actor, that appeals to his body as a work tool. From this perspective, the relationships between exercise, system and rehearsal are analyzed. Performance is not an esoteric and mystic act propitiated by the gods, it is a work that requires preparation, dedication and conscious inquiry. The actor or the actress that are unable to train in solitude, cannot contribute to a group, perhaps, this should be done without losing the perspective that theater is a collective act, in which communication plays an important role. For this reason, is fundamental to know how it is expressed, how it is signified and how a communication is begun between the actor and the spectator.

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

    In reinforcement learning, the learning algorithms frequently have to deal with both continuous state and continuous action spaces to control accurately. In this paper, the great capacity of kernel method for handling continuous state space problems and the advantage of actor-critic method in dealing with continuous action space problems are combined. Kernel-based continuous-action actor-critic learning ( KCACL ) is proposed grounded on the combination. In KCACL, the actor updates each action probability based on reward-inaction, and the critic updates the state value function according to online selective kernel-based temporal difference( OSKTD) learning. The experimental results demonstrate the effectiveness of the proposed algorithm.%强化学习算法通常要处理连续状态及连续动作空间问题以实现精确控制。就此文中结合Actor-Critic方法在处理连续动作空间的优点及核方法在处理连续状态空间的优势,提出一种基于核方法的连续动作Actor-Critic学习算法( KCACL)。该算法中,Actor根据奖赏不作为原则更新动作概率,Critic采用基于核方法的在线选择时间差分算法学习状态值函数。对比实验验证该算法的有效性。

    2009-02-01

    Full Text Available Remote sensed information on vegetation and soil moisture, namely the Normalised Difference Vegetation Index (NDVI and the Soil Water Index (SWI, is employed to monitor the spatial extent, severity and persistence of drought episodes over Continental Portugal, from 1999 to 2006. The severity of a given drought episode is assessed by evaluating the cumulative impact over time of drought conditions on vegetation. Special attention is given to the drought episodes that have occurred in the last decade, i.e., 1999, 2002 and particularly the major event of 2005. During both the 1999 and 2005 drought episodes negative anomalies of NDVI are observed over large sectors of Southern Portugal for up to nine months (out of eleven of the vegetative cycle. On the contrary, the 2002 event was characterized by negative anomalies in the northern half of Portugal and for a shorter period (eight out of eleven months. The impact of soil moisture on vegetation dynamics is evaluated by analyzing monthly anomalies of SWI and by studying the annual cycle of SWI vs. NDVI. While in the case of the drought episode of 1999 the scarcity of water in the soil persisted until spring, in the recent episode of 2005 the deficit in greenness was already apparent at the end of summer. The impact of dry periods on vegetation is clearly observed in both arable land and forest, and it is found that arable land presents a higher sensitivity. From an operational point of view, obtained results reveal the possibility of using the developed methodology to monitor, in quasi real-time, vegetation stress and droughts in Mediterranean ecosystems.

    Remote sensed information on vegetation and soil moisture, namely the Normalised Difference Vegetation Index (NDVI) and the Soil Water Index (SWI), is employed to monitor the spatial extent, severity and persistence of drought episodes over Continental Portugal, from 1999 to 2006. The severity of a given drought episode is assessed by evaluating the cumulative impact over time of drought conditions on vegetation. Special attention is given to the drought episodes that have occurred in the last decade, i.e., 1999, 2002 and particularly the major event of 2005. During both the 1999 and 2005 drought episodes negative anomalies of NDVI are observed over large sectors of Southern Portugal for up to nine months (out of eleven) of the vegetative cycle. On the contrary, the 2002 event was characterized by negative anomalies in the northern half of Portugal and for a shorter period (eight out of eleven months). The impact of soil moisture on vegetation dynamics is evaluated by analyzing monthly anomalies of SWI and by studying the annual cycle of SWI vs. NDVI. While in the case of the drought episode of 1999 the scarcity of water in the soil persisted until spring, in the recent episode of 2005 the deficit in greenness was already apparent at the end of summer. The impact of dry periods on vegetation is clearly observed in both arable land and forest, and it is found that arable land presents a higher sensitivity. From an operational point of view, obtained results reveal the possibility of using the developed methodology to monitor, in quasi real-time, vegetation stress and droughts in Mediterranean ecosystems.

    The objective of this paper is to analyse temporal birth weight variation, its relationship to the frequency of premature births in Portugal, and the influence of native and immigrant mothers' characteristics as well as to determine the possible existence of a pattern of temporal change in birth weight in the Iberian Peninsula as a whole. Individual mother-child data from the Portuguese National Institute of Statistics regarding live births (N = 2,661,542) permitted an analysis, for the first time, of weight at birth in Portugal from a bio-demographic perspective. The results obtained show that from 1988 to 2011 there was a gradual decline in the average weight at birth in Portugal that may be related to shifts in the duration of gestation. An initial rapid decline in the relative frequency of post-term births took place, followed by small variations from 1995 on. Logistic regressions indicated a pattern unaffected by maternal origin or the sex of the newborn. With regard to weeks of gestation, the odds values obtained were < 1 when the reference category was < 28 weeks. For this factor, no significant differences were found in relation to the mother's origin. Portuguese mothers over 35 years were associated with a higher incidence of low birth weight. Regardless of maternal origin, being a newborn of parity 1, and with the mother not in a couple, resulted in unfavourable outcomes with regard to low birth weight. On the other hand, long gestation periods and having secondary or university education constituted a protective factor.

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

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

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

    2008-01-01

    The recognition, involvement, and description of main actors influences the story line of the whole text. This is of higher importance as the text per se represents a flow of words and expressions that once it is read it is lost. In this respect, the understanding of a text and moreover on how the actor exactly behaves is not only a major concern: as human beings try to store a given input on short-term memory while associating diverse aspects and actors with incidents, the following approach represents a virtual architecture, where collocations are concerned and taken as the associative completion of the actors' acting. Once that collocations are discovered, they become managed in separated memory blocks broken down by the actors. As for human beings, the memory blocks refer to associative mind-maps. We then present several priority functions to represent the actual temporal situation inside a mind-map to enable the user to reconstruct the recent events from the discovered temporal results.

    Dirofilariosis is a severe vector-borne emergent disease that is spreading worldwide and becoming a serious threat to human and veterinary public health. Portugal, a Mediterranean country, has favorable climate conditions for mosquito development and survival. At present, accurate data on the prevalence and epidemiological pattern of dirofilariosis in Portugal is scarce and outdated. To study these trends, a project was developed to assess the current prevalence of Dirofilaria immitis infection in shelter dogs as well as the prevalence of Dirofilaria species present in three coastal regions in central Portugal: Coimbra, Santarém, and Setúbal. Blood samples were collected from 696 shelter dogs during three consecutive years: 2011, 2012, and 2013. A rapid immunomigration technique was performed to detect female D. immitis antigens. Concurrently, to detect and identify circulating microfilariae, a modified Knott's technique and acid phosphatase histochemical staining were also performed. Of the 696 dogs sampled, 105 were positive for D. immitis, with an overall prevalence of 15.1%. Forty of the 105 dogs were antigen negative but were positive for D. immitis microfilariae. Three animals were co-infected with D. immitis and Acanthocheilonema dracunculoides, and there was also one dog infected only with A. dracunculoides, all confirmed by polymerase chain reaction. The highest prevalence of canine heartworm during the 3-y period was in Setúbal (24.8%), followed by Coimbra (13.8%), and Santarém (13.2%), with significant inter-district differences. Our results demonstrate a higher prevalence of dirofilariosis compared with findings of previous studies and show an increasing rate of infection in the southern areas of Portugal attributed, at least in part, to bioclimatic and ecological factors. The present study updates the epidemiological situation and correlates the risk of dirofilariosis transmission within each region. These findings are highly relevant to both human

    Full Text Available We analyze the consequences of the introduction of the EU directed Bologna Process in Portuguese and Polish Universities. Specifically, we study how the Bologna Process has impacted in the employment situations of graduates in Portugal and Poland. Concerning methodology, we use available official data on the implementation of the Bologna Process in Poland and Portugal. We have found that the investment in Higher Education (HE stalled in both countries in the years since the implementation of the Bologna Process due to massive budgetary restrictions. Nevertheless, the stock of HE graduates increased massively, seemingly because the authorities thought that the free market should lead the HE market in the two countries. Employment prospects, unemployment prospects and wages of graduates continued to be much higher than those of non-graduates. But an unexpected divide appeared between graduates and Masters/PhDs, with important social consequences. While the first “saved” themselves and prospered going into high skilled jobs, the later had to endure minimum wage and underskilled occupations. The low payment for these youngsters was also justified because the supply of HE with Bologna increased but the demand by companies did not match. In fact, both Portugal and Poland have stronger needs in the demand side of the market than in the supply side. Finally, both markets continue to be essentially public and the experiences of privatization did not succeed to much. In terms of social implications, the Bologna Process faces in both countries the massive and decisive challenge of eliminating youth unemployment and emigration but this can only be done with the cooperation of companies that should create high paid and high skilled jobs. Only when this occurs the Bologna Process will achieve its ultimate goal of transforming Portugal and Poland in high skilled equibriuns. Let us hope it happens, for the good of the two countries and particularly for the

    Full Text Available This paper aims to demonstrate the advantages of adopting an ethnographic, actor interface approach to understanding the ongoing dynamics of rural development and policy intervention processes. It does so through the discussion of an EU-funded project orientated to introducing village-level forest-management practices in north-west China. The case highlights the ongoing everyday struggles over livelihoods and resources and focuses on the negotiations that take place between the various social actors involved. The case analysis is preceded by a broad-sweep overview of the rise of new ruralities and a discussion of the key elements of an actor interface analysis. The article concludes with a call for more cross-country and cross-regional studies of this kind.

  1. A New Efficient Key Management Protocol for Wireless Sensor and Actor Networks

    CERN Document Server

    Lee, Yunho

    2009-01-01

    Research on sensor networks has become much more active and is currently being applied to many different fields. However since sensor networks are limited to only collecting and reporting information regarding a certain event, and requires human intervention with that given information, it is often difficult to react to an event or situation immediately and proactively. To overcome this kind of limitation, Wireless Sensor and Actor Networks (WSANs) with immediate-response actor nodes have been proposed which adds greater mobility and activity to the existing sensor networks. Although WSANs share many common grounds with sensor networks, it is difficult to apply existing security technologies due to the fact that WSANs contain actor nodes that are resource-independent and mobile. Therefore, this research seeks to demonstrate ways to provide security, integrity, and authentication services for WSANs secure operation, by separating networks into hierarchical structure by each node's abilities and provides differ...

    Clinical tests have shown that the dynamics of a human arm, controlled using Functional Electrical Stimulation (FES), can vary significantly between and during trials. In this paper, we study the application of the actor-critic architecture, with neural networks for the both the actor and the critic, as a controller that can adapt to these changing dynamics of a human arm. Development and tests were done in simulation using a planar arm model and Hill-based muscle dynamics. We begin by training it using a Proportional Derivative (PD) controller as a supervisor. We then make clinically relevant changes to the dynamics of the arm and test the actor-critic's ability to adapt without supervision in a reasonable number of episodes. Finally, we devise methods for achieving both rapid learning and long-term stability. PMID:20689654

    2015-07-01

    The effectiveness of animal health surveillance systems depends on their capacity to gather sanitary information from the animal production sector. In order to assess this capacity we analyzed the flow of sanitary information regarding Highly Pathogenic Avian Influenza (HPAI) suspicions in poultry in Vietnam. Participatory methods were applied to assess the type of actors and likelihood of information sharing between actors in case of HPAI suspicion in poultry. While the reporting of HPAI suspicions is mandatory, private actors had more access to information than public actors. Actors of the upstream sector (medicine and feed sellers) played a key role in the diffusion of information. The central role of these actors and the influence of the information flow on the adoption by poultry production stakeholders of behaviors limiting (e.g. prevention measures) or promoting disease transmission (e.g. increased animal movements) should be accounted for in the design of surveillance and control programs.

    What is the relationship between the logic that guides political attitudes of constituencies and the logic of political actors, whose legitimacy is rooted in electoral choice of the constituencies? Classical approaches, such as the median voter theorem, view political actors as passively mirroring voters’ preferences. An alternative approach, that we suggested in the first part of this series of essays, assumes that how constituencies see the competences of political actors, is crucial, in th...

    The HIV/AIDS pandemia reshaped international relations and the world research landscape. New facilities have been created and new actors have emerged. New institutions has been grafted into the existing health infrastructure resulting in overlapping and sometimes conflicting actions. In this study we analyze this co-existence using the "Centre of Prevention and Voluntary testing of HIV/AIDS" (CPDV) in Cameroon as an example. The purpose is to show that the involvment of new actors in a health systems with multiple dysfunctions creates an environment leading to "straddling". This situation also raises legitimacy issues and leads to competition for position within the existing hierarchies. PMID:18689327

    International non-governmental organizations were among the first international actors that responded to the emergence of AIDS crisis in China. Since 1994, the number of international non-governmental organizations and charitable foundations working in AIDS related issue areas in China has grown steadily and substantially. Despite their organizational differences, most of these non-governmental actors present the characteristics of independent mission, localized practice and diverse working focus. Even though they are constrained by financial and other factors compared with multilateral and bilateral official assistance agencies, they have still played a unique role in fighting against AIDS in China as technical experts, public educators, and civil society supporters.

    Full Text Available OBJECTIVE To analyze the direct medical costs of HIV/AIDS in Portugal from the perspective of the National Health Service. METHODS A retrospective analysis of medical records was conducted for 150 patients from five specialized centers in Portugal in 2008. Data on utilization of medical resources during 12 months and patients’ characteristics were collected. A unit cost was applied to each care component using official sources and accounting data from National Health Service hospitals. RESULTS The average cost of treatment was 14,277 €/patient/year. The main cost-driver was antiretroviral treatment (€ 9,598, followed by hospitalization costs (€ 1,323. Treatment costs increased with the severity of disease from € 11,901 (> 500 CD4 cells/µl to € 23,351 (CD4 count ≤ 50 cells/ µl. Cost progression was mainly due to the increase in hospitalization costs, while antiretroviral treatment costs remained stable over disease stages. CONCLUSIONS The high burden related to antiretroviral treatment is counterbalanced by relatively low hospitalization costs, which, however, increase with severity of disease. The relatively modest progression of total costs highlights that alternative public health strategies that do not affect transmission of disease may only have a limited impact on expenditure, since treatment costs are largely dominated by constant antiretroviral treatment costs.

    Full Text Available Agro-food companies are aware that the technical and soft skills of their employees directly influence business performance and, consequently, improving those skills will enhance the effectiveness and efficiency of their companies. This paper presents the main results of the AgriTraining project “Training requirements for the agro-food industry". Activities in pursuit of the objectives of this project involved: (1 analysis of the training needs in the agro-food industry in Portugal; (2 analysis of the training provision and the training organizations; (3 analysis of market trends; (4 definition of a training strategy; and (5 adjustment and development of training strategies for the agro-food sector. This last activity comprised the development of training curricula, suitable for the food sector as a whole and adjusted for the specific needs of some traditional industries, in order to promote the development and competitiveness of the agro-food industry in Portugal. Such training curricula aimed to promote the uptake of innovative technologies and methodologies, increase the ability of agro-food industries to invest and take risks, and enable adoption of European Community standards for production and marketing. Gaps in training supply were identified and the training provision was updated according to the needs of the agro-food companies. It was determined that companies need and demand knowledge and innovation to increase their competitive position for internationalization purposes. It was possible to define a training strategy based on market-orientation for agro-food differentiation.

    Full Text Available The spatial variability of precipitation and drought are investigated for Portugal using monthly precipitation from 74 stations and minimum and maximum temperature from 27 stations, covering the common period of 1941–2006. Seasonal precipitation and the corresponding percentages in the year, as well as the precipitation concentration index (PCI, was computed for all 74 stations and then used as an input matrix for an R-mode principal component analysis to identify the precipitation patterns. The standardized precipitation index at 3 and 12 month time scales were computed for all stations, whereas the Palmer Drought Severity Index (PDSI and the modified PDSI for Mediterranean conditions (MedPDSI were computed for the stations with temperature data. The spatial patterns of drought over Portugal were identified by applying the S-mode principal component analysis coupled with varimax rotation to the drought indices matrices. The result revealed two distinct sub-regions in the country relative to both precipitation regimes and drought variability. The analysis of time variability of the PC scores of all drought indices allowed verifying that there is no linear trend indicating drought aggravation or decrease. In addition, the analysis shows that results for SPI-3, SPI-12, PDSI and MedPDSI are coherent among them.

    Trichinellosis is one of the most important foodborne parasitic zoonoses, caused by nematodes of the genus Trichinella. Pigs and other domestic and wild animals, including red foxes (Vulpes vulpes), are sources of Trichinella infection for human beings. Trichinella britovi is the major agent of infection in sylvatic animals and the most important species circulating in the European wildlife. The present study aimed at assessing Trichinella spp. infection in red foxes from the North of Portugal. Forty-seven carcasses of wild red foxes shot during the official hunting season or killed in road accidents were obtained between November 2008 and March 2010. In order to identify the presence of Trichinella spp. larvae in red foxes, an individual artificial digestion was performed using approximately 30 g of muscle samples. Larvae of Trichinella spp. were detected in one (2.1%) out of the 47 assessed foxes. After a multiplex polymerase chain reaction analysis, T. britovi was molecularly identified as the infecting species. The recognition of T. britovi in a red fox confirms that a sylvatic cycle is present in the North of Portugal and that the local prevalence of Trichinella infection in wildlife must not be ignored due to its underlying zoonotic risks.

    2013-06-01

    A series of experiments were conducted to characterize formaldehyde and acetaldehyde emissions from residential combustion of common wood species growing in Portugal. Five types of wood were investigated: maritime pine (Pinus pinaster), eucalyptus (Eucalyptus globulus), cork oak (Quercus suber), holm oak (Quercus rotundifolia) and pyrenean oak (Quercus pyrenaica). Laboratory experiments were performed with a typical wood stove used for domestic heating in Portugal and operating under realistic home conditions. Aldehydes were sampled from diluted combustion flue gas using silica cartridges coated with 2,4-dinitrophenylhydrazine and analyzed by high performance liquid chromatography with diode array detection. The average formaldehyde to acetaldehyde concentration ratio (molar basis) in the stove flue gas was in the range of 2.1-2.9. Among the tested wood types, pyrenean oak produced the highest emissions for both formaldehyde and acetaldehyde: 1772 ± 649 and 1110 ± 454 mg kg-1 biomass burned (dry basis), respectively. By contrast, maritime pine produced the lowest emissions: 653 ± 151 and 371 ± 162 mg kg-1 biomass (dry basis) burned, respectively. Aldehydes were sampled separately during distinct periods of the holm oak wood combustion cycles. Significant variations in the flue gas concentrations were found, with higher values measured during the devolatilization stage than in the flaming and smoldering stages.

    In summarizing the reasons for the fall of the Roman empire one has found about 210 significant ones. Without too much comparison the Roman empire and the EU natural gas market have similarities in connections between political authorities and the commercial actors in the European natural gas market. The area has consisted of several independent markets with different solutions that from 1988 has been tried integrated in an inner energy market. Several governmental and private actors have interest in this sector and both inhabitants and businesses are affected by alterations in a national natural gas market. This process is not yet finished. The thesis gives a broad description of the topic by including as many as possible of the EU member states. The topic is large and complex and the author has had to make a choice which parts to emphasize. There are chapters on the theoretical basis, the natural gas industry, what factors may explain the relationship between the political authorities and the commercial actors in the national natural gas market in each EU member and how does the EU Commission goals regarding free competition in the energy market affect the relationship between the political authorities and commercial actors in the national natural gas market

    Science.gov (United States)

    Kono, Tetsuya

    2014-03-01

    The concept of extended mind has been impressively developed over the last 10 years by many philosophers and cognitive scientists. The extended mind thesis (EM) affirms that the mind is not simply ensconced inside the head, but extends to the whole system of brain-body-environment. Recently, some philosophers and psychologists try to adapt the idea of EM to the domain of social cognition research. Mind is socially extended (SEM). However, EM/SEM theory has problems to analyze the interactions among a subject and its surroundings with opposition, antagonism, or conflict; it also tends to think that the environment surrounding the subject is passive or static, and to neglect the power of non-human actants to direct and regulate the human subject. In these points, actor-network theory (ANT) proposed by Latour and Callon is more persuasive, while sharing some important ideas with EM/SEM theory. Actor-network is a hybrid community which is composed of a series of heterogeneous elements, animate and inanimate for a certain period of time. I shall conclude that EM/SEM could be best analyzed as a special case of actor-network. EM/SEM is a system which can be controlled by a human agent alone. In order to understand collective behavior, philosophy and psychology have to study the actor-network in which human individuals are situated.

  13. Social health insurance without corporate actors: changes in self-regulation in Germany, Poland and Turkey.

    Science.gov (United States)

    Wendt, Claus; Agartan, Tuba I; Kaminska, Monika Ewa

    2013-06-01

    Social health insurance in Western Europe has for many years been characterized by self-regulation in which specific conditions of healthcare financing and provision have been regulated by social-insurance institutions through mutual self-governance. However, the principle of self-regulation has recently been weakened by increased state regulation and market competition, which were introduced in response to economic and social changes. Even in Germany, which has been regarded as an "ideal-type" health insurance system and in which self-regulation remains at the core of healthcare governance, more direct state intervention has gained in importance. On the other hand, in countries such as Poland and Turkey, where this tradition of self-regulation is missing, social health insurance is deemed a financing instrument but not an instrument of governance and corporate actors are not accorded a significant role in regulation. This article investigates how social health insurance systems are regulated in contexts in which corporate actors' role is either diminishing or absent by focusing on three crucial areas of regulation: financing, the remuneration of medical doctors, and the definition of the healthcare benefit package. In Germany, state regulation has increased in healthcare financing and remuneration while the role of corporate actors has grown in the definition of the benefits package. In Poland and Turkey, on the other hand, reforms have maintained the status quo in terms of the strong regulatory, budgetary, and managerial powers of the state and very limited involvement of corporate actors.

  16. Actor-critic models of the basal ganglia: new anatomical and computational perspectives.

    Science.gov (United States)

    Joel, Daphna; Niv, Yael; Ruppin, Eytan

    2002-01-01

    A large number of computational models of information processing in the basal ganglia have been developed in recent years. Prominent in these are actor-critic models of basal ganglia functioning, which build on the strong resemblance between dopamine neuron activity and the temporal difference prediction error signal in the critic, and between dopamine-dependent long-term synaptic plasticity in the striatum and learning guided by a prediction error signal in the actor. We selectively review several actor-critic models of the basal ganglia with an emphasis on two important aspects: the way in which models of the critic reproduce the temporal dynamics of dopamine firing, and the extent to which models of the actor take into account known basal ganglia anatomy and physiology. To complement the efforts to relate basal ganglia mechanisms to reinforcement learning (RL), we introduce an alternative approach to modeling a critic network, which uses Evolutionary Computation techniques to 'evolve' an optimal RL mechanism, and relate the evolved mechanism to the basic model of the critic. We conclude our discussion of models of the critic by a critical discussion of the anatomical plausibility of implementations of a critic in basal ganglia circuitry, and conclude that such implementations build on assumptions that are inconsistent with the known anatomy of the basal ganglia. We return to the actor component of the actor-critic model, which is usually modeled at the striatal level with very little detail. We describe an alternative model of the basal ganglia which takes into account several important, and previously neglected, anatomical and physiological characteristics of basal ganglia-thalamocortical connectivity and suggests that the basal ganglia performs reinforcement-biased dimensionality reduction of cortical inputs. We further suggest that since such selective encoding may bias the representation at the level of the frontal cortex towards the selection of rewarded

  17. [Shaken Baby Syndrome: fact or fiction in Portugal?].

    2011-12-01

    Shaken Baby Syndrome (SBS) is an unquestionable and current worldwide problem, as it is considered one of the most severe forms of child abuse, with significant morbidity and mortality among children under one year of age. In Portugal the actual incidence of SBS is still unknown and probably undervalued and underdiagnosed, but international literature reports incidences between 14 and 40.5 per 100.000 children a year in several different countries. It is classically considered SBS to consist of shaking a child repeatedly and violently, inducing a cervical whiplash like movement. Due to the child's development stage, this external force of acceleration/deceleration acting on the head and cervical musculature may cause several lesions, specially subdural, subarachnoid and retinal hemorrhage, and sometimes even bone fractures. However, there is no unanimity concerning this trauma mechanism, especially on the requirement of direct trauma to the head leading to intracranial lesions, since a satisfactory biomechanical model to test it is still lacking. Its diagnosis is controversial, difficult and has important legal and family implications, always adding an emotional element to it, susceptible of withholding the necessary objectivity. In order to substantiate a strong suspicion it is thus mandatory to correlate the clinical history, the physical examination and all the diagnostic auxiliary exams. Consequences may range from mild to fatal, encompassing the child's psychological, cognitive, physical and sensory-motor development, on a short or long term basis. Nevertheless, from a global perspective, its prognosis is almost always poor. So, education and prevention assume primary importance in order to reduce incidence, morbidity and mortality of the SBS. Countries like the U.S.A, Scotland, France, Germany, Switzerland, Canada, Estonia and Japan have long been interested in studying this syndrome's trauma mechanism and incidence, as well as in the development of

    2016-04-01

    Ançã is located in the Lusitanian Basin (western Meso-Cenozoic sedimentary basin), in the municipality of Cantanhede, close to Coimbra, Portugal. This constitutes the northernmost Dogger (Bajocian) limestone sequence in Portugal. The use of the Ançã limestones is documented since the Roman occupation of the Iberian Peninsula. It was used for the construction of houses, palaces, churches, fine sculptures, carving, paving and for the production of lime. These limestones vary from white and very soft varieties, with very high porosity used for sculpture and carving to white and hard varieties used for masonry and as aggregates and to white to bluish with low porosity and high strength varieties, mainly used for paving. The softer and whiter variety is worldwide known as Ançã Stone (Pedra de Ançã) exhibiting a porosity of 26-29 %. It became famous after being largely used by Coimbra most famous Renaissance sculptors like João de Ruão and Nicolau de Chanterenne. The Pedra de Ançã was used mainly in the region of Coimbra, but also in several other places in Portugal, in Santiago de Compostela, Spain, and Brazil. Some examples of heritage in Coimbra using the Pedra de Ançã are the renaissance portal of the Saint Cross Church, the tombs of the first two Portuguese kings located in this church, the altar of the Saint Cross Church or of the Old Cathedral, or in sculptures at the University of Coimbra. It is quite prone to deteriorate when exposed to atmospheric agents and to soluble salts, mainly due to its high porosity. Deteriorated surfaces needing treatment constitute difficult conservation problems, especially when consolidation and protection treatments are required.

Most of the traditional quarries are abandoned and those still in activity are mainly used to produce crushed aggregates, limestone

    2015-04-01

    Portugal is one of the major fire-prone European countries, mainly due to its favourable climatic, topographic and vegetation conditions. Compared to the other Mediterranean countries, the number of events registered here from 1980 up to nowadays is the highest one; likewise, with respect to the burnt area, Portugal is the third most affected country. Portuguese mapped burnt areas are available from the website of the Institute for the Conservation of Nature and Forests (ICNF). This official geodatabase is the result of satellite measurements starting from the year 1990. The spatial information, delivered in shapefile format, provides a detailed description of the shape and the size of area burnt by each fire, while the date/time information relate to the ignition fire is restricted to the year of occurrence. In terms of a statistical formalism wildfires can be associated to a stochastic point process, where events are analysed as a set of geographical coordinates corresponding, for example, to the centroid of each burnt area. The spatio/temporal pattern of stochastic point processes, including the cluster analysis, is a basic procedure to discover predisposing factorsas well as for prevention and forecasting purposes. These kinds of studies are primarily focused on investigating the spatial cluster behaviour of environmental data sequences and/or mapping their distribution at different times. To include both the two dimensions (space and time) a comprehensive spatio-temporal analysis is needful. In the present study authors attempt to verify if, in the case of wildfires in Portugal, space and time act independently or if, conversely, neighbouring events are also closer in time. We present an application of the spatio-temporal K-function to a long dataset (1990-2012) of mapped burnt areas. Moreover, the multivariate K-function allowed checking for an eventual different distribution between small and large fires. The final objective is to elaborate a 3D

    Located on the western Iberian Peninsula, Portugal constitutes a key area for accretionary terrane and basin research, providing the best opportunity to probe a crustal formation shaped by the Paleozoic Variscan orogeny followed by the Mesozoic-Cenozoic extensions. The geology of Portugal documents a protracted history from Paleozoic basement formation to the Mesozoic opening of the North Atlantic Ocean. The inheritance of such complex geologic history is yet to be fully determined, playing an important role in the current geodynamic framework influencing, for example, the observed regional seismicity. The physical properties of its crust have largely remained undetermined so far, with unevenly distributed knowledge on the spatial distributions of a detailed crustal structure. Also, the deep seismic reflection/refraction surveys conducted in Western Iberia do not provide a clear picture of the regional characteristics of the crust. Using Seismic Broad Band observations from a dense temporary deployment, conducted between 2010 and 2012 in the scope of the WILAS project and covering the entire Portuguese mainland, we computed a 3D anisotropic model from ambient seismic noise. The dispersion measurements were computed for each station pair using empirical Green's functions generated by cross-correlating one-day-length seismic ambient-noise records. After dispersion analysis, group velocity measurements were regionalized to obtain 2D anisotropic tomographic images. Afterwards, the dispersion curves, extracted from each cell of the 2D group velocity maps, were inverted as a function of depth to obtain a 3D shear wave anisotropic model, using a bayesian approach. A simulated annealing method, in which the number of splines that describes the model, is adapted within the inversion. The models are jointly interpreted with the models gathered from Ps receiver functions as well as with the regional seismicity, enabling to obtain a more detailed picture of the crustal

  4. Ownership Structure and Earnings Management: Evidence from Portugal

    2012-03-01

    Full Text Available This paper examines the relationship between corporate ownership structure in Portugal and earnings management. The Portuguese governance structure is characterised by the dominance ofthe largest shareholder who typically exercises significant influences on management decisions directly or indirectly. Existing literature suggests that ownership structure decreases the incentive to manage earnings but also provides the opportunity and incentive to manipulate earnings. Therefore, the main purpose of this paper is to analyse whether a firm’s ownership structure (measured with three variables: managerial ownership, ownership concentration and institutional ownershipexacerbate or alleviate earnings management. Using a sample of 34 non-financial listed Portuguese firms for years from 2002 to 2007, we find that discretionary accruals as a proxy for earnings management is negatively related both to managerial ownership and to ownership concentration. The study’s results suggest that both managerial ownership and ownership concentration improvethe quality of annual earnings by reducing the levels of earnings management.

    Full Text Available Facing the challenges brought by Higher Education growth, the Higher Education Institutions (HEIs created the Psychological Support Services. They seek to help the adaptation to the university setting, enhancing the overall students´ development and their integration in the labor market. This qualitative research studies the structure of the Psychological Support Services in HEIs of Portugal and the main activities developed by educational psychologists. Interviews were conducted with eight services and showed that all services are designed for students. Although the most frequent activity is the students' psychological consultation, educational psychologists also develop a variety of interventions: skill development programs, support to students with special needs, and mentoring programs to welcome new students. Traditionally the services were oriented by an individual intervention and in response to the students' problem. Nowadays they are working with other agents and in a preventive way. Actions directed to educational projects and the institutional evaluation could promote a qualitative change in services.

  10. Assessing fire risk in Portugal during the summer fire season

    Science.gov (United States)

    Dacamara, C. C.; Pereira, M. G.; Trigo, R. M.

    2009-04-01

    Since 1998, Instituto de Meteorologia, the Portuguese Weather Service has relied on the Canadian Fire Weather Index (FWI) System (van Wagner, 1987) to produce daily forecasts of fire risk. The FWI System consists of six components that account for the effects of fuel moisture and wind on fire behavior. The first three components, i.e. the Fine Fuel Moisture Code (FFMC), the Duff Moisture Code (DMC) and the Drought Code (DC) respectively rate the average moisture content of surface litter, decomposing litter, and organic (humus) layers of the soil. Wind effects are then added to FFMC leading to the Initial Spread Index (ISI) that rates fire spread. The remaining two fuel moisture codes (DMC and DC) are in turn combined to produce the Buildup Index (BUI) that is a rating of the total amount of fuel available for combustion. BUI is finally combined with ISI to produce the Fire Weather Index (FWI) that represents the rate of fire intensity. Classes of fire danger and levels of preparedness are commonly defined on an empirical way for a given region by calibrating the FWI System against wildfire activity as defined by the recorded number of events and by the observed burned area over a given period of time (Bovio and Camia, 1998). It is also a well established fact that distributions of burned areas are heavily skewed to the right and tend to follow distributions of the exponential-type (Cumming, 2001). Based on the described context, a new procedure is presented for calibrating the FWI System during the summer fire season in Portugal. Two datasets were used covering a 28-year period (1980-2007); i) the official Portuguese wildfire database which contains detailed information on fire events occurred in the 18 districts of Continental Portugal and ii) daily values of the six components of the FWI System as derived from reanalyses (Uppala et al., 2005) of the European Centre for Medium-Range Weather Forecasts (ECMWF). Calibration of the FWI System is then performed in two

We will try to answer two fundamental research questions: 1 What motivates popular support for political parties (or lack thereof? 2 Why does antiparty rhetoric resonate with some citizens, but not with others? The empirical data and statistical regression models used allow the following conclusion: in the eyes of Portuguese citizens, parties have become a kind of “necessary evil”, being criticized for “what they actually do” and supported for “what they are supposed to do”.

    Laukkanen, Tommi; Cruz, Pedro

    This study compares two distinct European countries namely Finland and Portugal in terms of consumer resistance to mobile banking services. We explored how the five adoption barriers namely usage, value, risk, tradition and image, derived from the earlier literature, differ between these two countries. Using an Internet questionnaire a total of 3.597 usable responses was collected. A confirmatory factor analysis was implemented with SEM to build the constructs’ latent score levels. Using non-parametric difference tests we concluded that the resistance is significantly lower among the Portuguese online bank customers in terms of four out of the five barriers. The results can be used for a better understanding and enhancement of adoption of this specific case of mobile communication.

We study whether religion (measured as church attendance and opinions about moral issues influences voting for the two main political parties. Results show a different relationship between religion and voting in both countries: only in Spain religious beliefs play an important role in electoral behaviour. We claim that to account for this finding several factors need to be considered, namely the different configuration of the party systems and religious maps, the distinctive mechanisms linking religious identities with voting and, above all, the important role played by political leaders in activating religiosity within the electoral competition.

    Acute viral bronchiolitis is a common cause for infant hospital admissions. Of all etiological agents, respiratory syncytial virus (RSV) is commonly the most frequent. The present study assesses relationships between atmospheric factors and RSV infections in under 3-year-old patients admitted to the Inpatient Paediatric Service of Vila Real (North of Portugal). For this purpose, (1) clinical files of children admitted with a diagnosis of acute bronchiolitis from September 2005 to December 2015 (>10 years) were scrutinised and (2) local daily temperature/precipitation series, as well as six weather types controlling meteorological conditions in Portugal, were used. Fifty-five percent of all 770 admitted children were effectively infected with a given virus, whilst 48 % (367) were RSV+, i.e. 87 % of virus-infected children were RSV+. The bulk of incidence is verified in the first year of age (82 %, 302), slightly higher in males. RSV outbreaks are typically from December to March, but important inter-annual variability is found in both magnitude and shape. Although no clear connections were found between monthly temperatures/precipitation and RSV outbreaks apart from seasonality, a linkage to wintertime cold spells is apparent on a daily basis. Anomalously low minimum temperatures from the day of admittance back to 10 days before are observed. This relationship is supported by anomalously high occurrences of the E and AA weather types over the same period, which usually trigger dry and cold weather. These findings highlight some predictability in the RSV occurrences, revealing potential for modelling and risk assessments.

    Atmospheric forecasting and predictability are important to promote adaption and mitigation measures in order to minimize drought impacts. This study estimates hybrid (statistical-dynamical) long-range forecasts of the regional drought index SPI (3-months) over homogeneous regions from mainland Portugal, based on forecasts from the UKMO operational forecasting system, with lead-times up to 6 months. ERA-Interim reanalysis data is used for the purpose of building a set of SPI predictors integrating recent past information prior to the forecast launching. Then, the advantage of combining predictors with both dynamical and statistical background in the prediction of drought conditions at different lags is evaluated. A two-step hybridization procedure is performed, in which both forecasted and observed 500 hPa geopotential height fields are subjected to a PCA in order to use forecasted PCs and persistent PCs as predictors. A second hybridization step consists on a statistical/hybrid downscaling to the regional SPI, based on regression techniques, after the pre-selection of the statistically significant predictors. The SPI forecasts and the added value of combining dynamical and statistical methods are evaluated in cross-validation mode, using the R2 and binary event scores. Results are obtained for the four seasons and it was found that winter is the most predictable season, and that most of the predictive power is on the large-scale fields from past observations. The hybridization improves the downscaling based on the forecasted PCs, since they provide complementary information (though modest) beyond that of persistent PCs. These findings provide clues about the predictability of the SPI, particularly in Portugal, and may contribute to the predictability of crops yields and to some guidance on users (such as farmers) decision making process.

    Stray cats live in high-density colonies in urban areas and pose a health hazard to household cats and humans. In Portugal, information on the parasitic fauna of stray cats is limited and relies mostly on results from faecal analysis. The present survey aimed to determine the prevalence, diversity and intensity of parasites in stray cats from the urban area of Lisbon by means of parasitological necropsy. Internal organs were collected from 162 cats captured in different areas of the city and systematically subjected to parasitological dissection. Helminths were identified by macro- and microscopic examination and protozoa by faecal floatation and sedimentation techniques. The overall prevalence of parasites was 90.7% (95% confidence interval (CI): 85.3-94.6%). A total of 12 parasite species was recorded: Cystoisospora felis (14.2%), Cystoisospora rivolta (46.3%), Sarcocystis sp. (1.2%), Ancylostoma tubaeforme (19.1%), Toxocara cati (38.3%), Ollulanus tricuspis (30.9%), Aelurostrongylus abstrusus (12.4%), Eucoleus aerophilus (0.6%), Taenia taeniaeformis (3.1%), Dipylidium caninum (53.1%), Joyeuxiella pasqualei (15.4%) and Diplopylidium nölleri (3.7%). Overall mean species richness was 2.36 ±  1.52. Helminth mean intensity was highest for O. tricuspis (285.8), followed by D. caninum (42.4), J. pasqualei (14.4), A. tubaeforme (8.1) and T. cati (5.9). The prevalence and variety of parasites found in our sampling are substantially higher than the numbers previously reported in Portugal. Some of the parasites, including T. cati and A. tubaeforme, are zoonotic, which emphasizes the need for parasite control strategies based on demographic containment of stray cat populations in urban areas to promote public health protection.

    Miranda do Douro, located in the northeastern region of Portugal, has notable characteristics not only from a geographic or naturalistic point of view, but also from a cultural perspective. A remarkable one is the coexistence of two different languages: Portuguese and Mirandese, the second being an Astur-Leonese dialect. The current persistence of the Astur-Leonese dialect in this population falls on the singularity of the region: relative isolation, implying difficulties to communicate with other Portuguese regions, while the same location facilitated the establishment of social and commercial relationships with adjacent Spanish territories, origin of the Astur-Leonese language. The objective of this study was to characterize the population from Miranda through the analysis of maternal lineages in order to evaluate whether its mitochondrial DNA diversity fitted the patterns previously reported for other populations from the Iberian Peninsula. Viewing that, the entire control region of mitochondrial DNA from 121 individuals was examined. Miranda showed a haplogroup composition usual for a Western European population, in the sense that as high as 63.6% of sequences belonged to macro-haplogroup R0. Lineages ascribed to have an African (L2a and L1b) origin, were detected, but reaching an amount commonly found in Portugal. Miranda also presented a few haplogroups typically found in Jewish populations, while rarely observed in other Iberian populations. The finding can be explained by gene flow with crypto-Jew communities that since long are known to be established in the region where Miranda is located. In Miranda, both genetic and nucleotide diversities presented low values (0.9292 ± 0.0180 and 0.01101 ± 0.00614 respectively) when compared to populations from its micro-geographical framework, which constitute a sign of population isolation that certainly provided conditions for the survival of the Astur-Leonese dialect in the region.

Incluso con estas mejoras, las tasas de frecuencia de accidentes de trabajo y de enfermedades profesionales en Portugal todavía se mantienen muy elevadas necesitando, por tanto, estrategias más "agresivas" para concienciar la sociedad portuguesa en torno a las políticas públicas de SST efectivamente promotoras de prevención de riesgos profesionales y de la promoción de la salud de quien trabaja. Es por tanto indispensable que la protección de la salud y de la seguridad de los trabajadores en los puestos de trabajo sea encarada como un conjunto de actividades de indiscutible utilidad para todos los representantes del mundo del trabajo e que la agenda política pase a valorizar, aún más, la promoción de espacios de trabajo saludables y seguros, con la consecuente valorización de las variables individuales en la estrategia nacional de salud y seguridad.In the present work, the author analyzes several aspects of Occupational Health and Safety (OHS in Portugal.

Para su realización se ha consultado fundamentalmente prensa histórica portuguesa, tanto general como específica del ámbito deportivo. Los resultados obtenidos muestran que la introducción del jujutsu en Portugal se produjo fundamentalmente a través del mundo del espectáculo, mediante actuaciones de expertos japoneses. Las notables diferencias técnicas y corporales entre estos luchadores japoneses y los luchadores profesionales de lucha libre y grecorromana de la época, a los que habitualmente solían derrotar, contribuyeron a generar un potente imaginario de las artes de combate orientales como sistemas superiores de cultura física y defensa personal. No obstante, a pesar del éxito del jujutsu este no logró afianzarse sólidamente en Portugal, desapareciendo progresivamente de la escena pública desde principios de la segunda década del siglo XX.-------------------------------------------------------------------------------The present study analyzes the introduction of jujutsu in Portugal at the beginning of the 20th century. Mainly, historical Portuguese newspapers were reviewed, both general and specific from sports field. Results show that the introduction of jujutsu in Portugal was principally conduced via the show business through exhibitions performed by Japanese experts. Significant technical and physical differences between the Japanese fighters and the professional Freestyle and Greco-roman fighters, who were usually defeated by the former, contributed to create a powerful imaginary of the eastern fighting arts as superior systems of physical culture and self-defence. However, in spite of jujutsu’s success, it did not come to be strongly established in Portugal, vanishing progressively off the public scene since the beginning of the 1910s.

    In November 2002 a special exhibition on climate issues opened in the German Museum for Science and Techniques ('Deutsches Museum') in Munich. Within this exposition we present an interactive game in which visitors control future climate policy by adopting the role of either the government, a CEO (Chief Executive Officer) of a global company or a typical private household of an industrialized country. The players endeavor to maintain a sustainable climate in the future (global goal) while pursuing their own individual welfare goals. Task of the exhibition visitor is to combine the personal interests of the actor he is adopting with the global goal. The individual goal of government is maintain economic growth while avoiding conflicts due to inter-regional or societal inequalities. The CEO seeks to maximize total profits (business earnings). The goal of households is to maximize wages and interest earnings. The evolution of the economic system and climate is governed by the decisions of the actors. Government sets economic side conditions in terms of carbon taxes, subsidies for R&D or market infusion support for climate-friendly technologies, and transfers development aid to less advanced regions. The CEOs decide how much to invest in a number of alternative investment options and in which region. Households influences the economy by their purchasing and savings decisions. The model considers four regions, three real actors (mentioned above) and two different goods (climate-adverse and a climate-friendly). We introduce four different kinds of energy (coal, oil/gas, nuclear, renewable). A World Bank handles money flows. At different points in time the actors can cooperate with other actors in order to reach the global goal Stochastic elements regarding future technology and future climate are included. A touch-screen monitor with user friendly interface is used to present animations and videos. An animated climate scientist uses a climate simulator to compute future

Some of those reforms were motivated by the participation of the European Union and its member States in the World Trade Organization. This paper aims to analyze the role of the European Union as an actor in that organization, paying special attention to its mixed legal nature – EU and Member States. With that purpose, the evolution of the relationship between the EU member States and the EU itself as simultaneous actors at the WTO is studied. The division of competences is also reviewed. Finally, the analysis of the EU position in different negotiation rounds (Uruguay, Doha for the agricultural sector is reviewed as an example of the evolution in the protection of European interests.

  2. Is carbon lock-in blocking investments in the hydrogen economy? A survey of actors' strategies

    International Nuclear Information System (INIS)

    The difficulty of introducing hydrogen and fuel cells in the market stems from the fact that they are not an evolutionary innovation such as biofuels or hybrid cars. Instead they create a disruption in technological utilization. The domination of oil technologies sets a socio-economical context favoring actors involved in the current paradigm, and gives less opportunity to alternative fuels to develop and challenge the status quo. If this hypothesis is correct, then companies interested in the hydrogen economy would not become active because of an unstable context or contradictory interests concerning the replacement of the present system. A review of actions and announcements of main actors shows that technology readiness and the absence of infrastructure are the major justifications to delay investments. Some measures are discussed, which could be deployed in order to reduce uncertainties, such as regulation of carbon emissions from cars, technological subvention, and partnerships for infrastructure implementation.

    Full Text Available Much of the discourse surrounding national intercity passenger rail service in the United States revolves around why it has lagged so far behind European and Asian counterparts. However, a more interesting question might be why it has survived despite competition from faster, more nimble transport modes, discriminatory public policy, and the ascension of neoliberal discourse hostile to public endeavor. This paper uses the concept of durability in actor-network theory to offer some insights into how the system has achieved a remarkable but problematic stability, and how that durability relates to an imagined role for national intercity passenger rail in a future of increasingly constrained material resources. This paper also demonstrates the application of actor-network theory (ANT in a way that can serve as a useful introduction to and template for the use of that methodology.

    CERN Document Server

    Plantikow, Stefan

    2011-01-01

    The logic for handling of application requests to a staged, event-driven architecture is often distributed over different portions of the source code. This complicates changing and understanding the flow of events in the system. The article presents an approach that extracts request handling logic from regular stage functionality into a set of request scripts. These scripts are executed step-wise by sending continuations that encapsulate their request's current execution state to stages for local processing and optional forwarding of follow-up continuations. A new internal domain specific language (DSL) that aims to simplify writing of request scripts is described along with its implementation for the scala actors library. Evaluation results indicate that request handling with actor continuations performs about equally or better compared to using separate stages for request handling logic for scripts of at least 3 sequential steps.

    Full Text Available Actor-network theory (ANT shows how scientific and technical innovations may take the form of a socio-technical network, by the aggregation of humans and non-humans (Callon, 1986; Latour, 1989. This article reflects on the contributions and limits of ANT to examine a particular object of research presenting regular innovations: the outdoor recreation. Firstly, the integration of non-humans to the analysis (Latour, 2006 is relevant in the study of nature sports because physical entities transform the action and involve specific associations. Then it is a particular epistemological positioning that shakes the dichotomies up and givesimportance to the reflexive activity of actors. Finally, understanding the development of collectives is useful for the study of nature sports. The construction of a social coexistence between different activities (sports activities and other activities strongly questions the political transformation of contemporary democracy, including the establishment of a participatory management.

    Full Text Available The higher goal of rehabilitation robot is to aid a person to achieve a desired functional task (e.g., tracking trajectory based on assisted-as-needed principle. To this goal, a new adaptive inverse optimal hybrid control (AHC combining inverse optimal control and actor-critic learning is proposed. Specifically, an uncertain nonlinear rehabilitation robot model is firstly developed that includes human motor behavior dynamics. Then, based on this model, an open-loop error system is formed; thereafter, an inverse optimal control input is designed to minimize the cost functional and a NN-based actor-critic feedforward signal is responsible for the nonlinear dynamic part contaminated by uncertainties. Finally, the AHC controller is proven (through a Lyapunov-based stability analysis to yield a global uniformly ultimately bounded stability result, and the resulting cost functional is meaningful. Simulation and experiment on rehabilitation robot demonstrate the effectiveness of the proposed control scheme.

    Animals' rhythmic movements, such as locomotion, are considered to be controlled by neural circuits called central pattern generators (CPGs), which generate oscillatory signals. Motivated by this biological mechanism, studies have been conducted on the rhythmic movements controlled by CPG. As an autonomous learning framework for a CPG controller, we propose in this article a reinforcement learning method we call the "CPG-actor-critic" method. This method introduces a new architecture to the actor, and its training is roughly based on a stochastic policy gradient algorithm presented recently. We apply this method to an automatic acquisition problem of control for a biped robot. Computer simulations show that training of the CPG can be successfully performed by our method, thus allowing the biped robot to not only walk stably but also adapt to environmental changes.

    Full Text Available Raahe is a medium-sized Finnish town on the western coast of Northern Finland. It has declared itself to become the wind power capital of Finland. The aim of this paper is to find out what being a wind power capital can mean in practice and how it can advance the local industrial business. First, the theoretical framework of this systematic review study was formed by searching theoretical information about the forms of industrial clusters, and it was then examined what kinds of actors take part in these types of clusters. Finally, the actors of the case area were studied. The core companies of wind power clusters are the wind turbine manufacturers, component manufacturers, developers of the wind farms, wind power operators, and service and maintenance organizations. Understanding of the wind power cluster structure may help decision makers to develop the best possible conditions for the emergence of clusters.

  11. Monitoring communication outbreaks among an unknown team of actors in dynamic networks

    This paper investigates the detection of communication outbreaks among a small team of actors in time-varying networks. We propose monitoring plans for known and unknown teams based on generalizations of the exponentially weighted moving average (EWMA) statistic. For unknown teams, we propose an efficient neighborhood-based search to estimate a collection of candidate teams. This procedure dramatically reduces the computational complexity of an exhaustive search. Our procedure consists of two steps: communication counts between actors are first smoothed using a multivariate EWMA strategy. Densely connected teams are identified as candidates using a neighborhood search approach. These candidate teams are then monitored using a surveillance plan derived from a generalized EWMA statistic. Monitoring plans are established for collaborative teams, teams with a dominant leader, as well as for global outbreaks. We consider weighted heterogeneous dynamic networks, where the expected communication count between each p...

  12. Local authorities and electricity: territories, actors and issues within the local public service in France

    International Nuclear Information System (INIS)

    In France, the role of local authorities in the organization of the electricity supply system is largely unknown mainly due to the size of the state-owned utility Electricite de France (EDF). Local authorities and their groupings played a major role in the electrification of the national territory and have kept important prerogatives as conceding authorities of this service of general interest. These groupings also became the tools of the soft power of local actors. The geopolitical analysis of the relationships between local municipalities and electric power stakeholders shows the diversity of actors and opinions. Stuck between market liberalization issues and decentralization to local authorities, these groupings tend to reinforce their competencies. Furthermore, decentralization goes along with a reinforcement of the political involvement in local energy policy and with conflicts on the adequate territorial scale for theses policies. (author)

  13. New actors in environmental management: The case of the civil society in Ensenada

    Full Text Available The environment is a complex space where multiple interests converge, so the traditional government has been insufficient to respond to the new demands of the environmental management. In this sense, the theory governance suggests a bigger role for social actors in decision-making for a more effective resolution of environmental problems. This article focuses on the Civil Society Organizations (cso’s of Ensenada, due to its relevance in the public sphere and the ecological value of the area. Twenty two csos, its participants and the network of actors were characterized through a survey. It was found that three types of csos are focusing on the conservation agenda and urban sustainability.

  15. Hydraulic and marine energies. Market evolution and perspectives on the medium term for the sector actors

    International Nuclear Information System (INIS)

    In its first part, this report proposes an analysis of the hydraulic and marine energy sector and of its perspectives through the identification of its main activity determining factors, a presentation of the activity evolution until 2015, and a discussion of the process of concession renewal, and of the development of small hydroelectric projects. The second part presents and comments the financial performance of enterprises belonging to the sector, and the third part an overview of highlights and of development focuses of operators (increase of production capacities, concession renewals, international development, and diversification in other renewable energies). The third part reports an analysis of the sector context: structural brakes and drivers, hydraulic world market, hydraulic French market. The three last parts propose an analysis of the sector economic structure and of actors, data sheet for operators, equipment manufacturers and engineering companies, and economic and financial indicators for 192 operators which allow a comparative overview of these actors

  16. Deepening of security conception and violent non-state actors as the challengers of human security

    Traditional security approach focuses on the state and the problem of national security. However, it is argued that individuals should be privileged as the referent object of security. Human security concept consists of actors and agendas that are not evaluated by traditional security approach. Human security holds that the security of the state does not necessarily ensure the security of its citizens. The nation-state is experiencing an erosion of power and sovereignty, ...

    Empathy is at the heart of all nurse-patient interactions. Yet empathy often declines during students' nursing education. Nurse educators are challenged to find ways to offset this decline. A mixed-methods research design was used to assess whether an educational intervention using standardized actors influenced nursing student empathy. The results suggest that the educational intervention holds potential for improving empathy in nursing students.

    Actors and the Socio-Political and Symbolic OrderIn this thesis I have shown how women and men, all part of a small ejido in Western Mexico, are actively engaged in struggling to manage the social constraints and conditions they encounter. We have seen that coping with the process of agricultural change and the incorporation of the village and farm enterprise into the wider economic, political and institutional environment requires new skills and knowledge. Male and female farmers are differe...

  20. Virtual actors and avatars in a flexible user-determined-scenario environment

    VRaptor, a VR system for situational training that uses trainer-defined scenarios is described. The trainee is represented by an avatar; the rest of the virtual world is populated by virtual actors, which are under the control of trainer-defined scripts. The scripts allow reactive behaviors, but the trainer can control the overall scenario. This type of training system may be very useful in supplementing physical training.
