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

    PubMed Central

    2011-01-01

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

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

    The Ria de Aveiro (Portugal) is a coast al lagoon adjacent to the Atlantic Ocean and it has an inner bay (Laranjo bay) that received a highly contaminated effluent discharged by a mercury cell chlor-alkali plant from the 1950s until 1994. The aim of this study is to review in a holistic way several research studies that have been carried out in the Ria de Aveiro, in order to evaluate the remobilization of the mercury accumulated within the system and the recovery of the lagoon. The spatial distribution of the total mercury in the surrounding terrestrial environment has also been considered. Results indicate that the main mercury contamination problems in the Ria de Aveiro are confined to the Laranjo bay. Mercury export to the coastal waters and its impact on the nearshore compartments (water column, sediment and biota) are low. No direct effects of the mercury from nearby industrial activities were detected in Aveiro's urban soils, although historical mercury contamination is still affecting soil quality in the immediate vicinity of the chlor-alkali plant, located in Estarreja. Moreover, macrophyte harvesting for human direct or indirect use and the consumption of mussels, crabs and the sea bass from the Laranjo bay may constitute a health risk. Further studies focusing on developing skills for the restoration of the ecosystem are presently underway.

    Ria de Aveiro (Portugal) is a shallow coastal lagoon of high economic and ecological importance. Hardly any data on its chemical pollution by polar organic pollutants are available in literature. This study focused on the presence and sources of a series of phenolic endocrine-disrupting compounds (EDCs) in this area, including parabens, alkylphenolic compounds and bisphenol-A (BPA). A number of possible sources of pollution are present in the area, including the large harbours present in the lagoon, the city of Aveiro and the rivers discharging into the area. A recently constructed submarine wastewater outfall, located a few kilometres from the lagoon inlet has also been suggested as a possible source of pollution to Ria de Aveiro in several publications. The aim of the current field study was to investigate the occurrence and main sources of phenolic endocrine disruptors in Ria de Aveiro. An extensive sampling campaign was performed, with surface water and wastewater grab samples taken at over 50 locations, in duplicate on different days. Samples were treated using solid phase extraction and analysed by liquid chromatography tandem mass spectrometry. Concentrations in lagoon water were generally low: not exceeding 20 ng/L for most analytes. Levels in river water exceeded those in the lagoon by a factor 3 to 500 (o-phenylphenol (PhP) and nonylphenoxy ethoxy acetic acids (A9PEC), respectively), with concentrations up to 700 ng/L for BPA and 7,300 ng/L for A9PEC. Samples from the harbours showed EDC levels similar to those in the rest of the lagoon, but in the city of Aveiro, elevated concentrations were observed for alkylphenol ethoxylates (A9PEO), A9PEC, PhP and BPA. Wastewater effluents showed low levels for parabens, whilst alkylphenolic compounds reached several micrograms per litre. The effluents are discharged into the ocean via a submarine outfall, but as marine water near the outfall showed slightly elevated concentrations only for A9PEO, it does not seem to

    Ria de Aveiro, which is located in the centre of Portugal (40° 38' N, 8° 45' W), is a well-mixed and complex coastal lagoon that is separated from the sea by a sandy barrier and connects with the Atlantic through an artificial inlet. Tidal currents are the main factor controlling the lagoon's hydrodynamics and, to a great extent, the sedimentary dynamic. The inner lagoonal zones receive input from several rivers and experience the pressure caused by the accumulation of organic matter and pollutants (namely, trace metals) from diverse anthropic activities. This paper is the first piece of work aiming to recognize, characterize and explain the main benthic foraminiferal biotopes in Ria de Aveiro. To provide a broad overview of this kind of setting, our results are compared to those of previous published studies conducted in similar transitional environments. The research is based on an investigation of 225 sites spread throughout this ecosystem. Utilizing a statistical approach, this study analyses the details of dead benthic foraminiferal assemblages composed of 260 taxa, the texture and composition (mineralogical and geochemical) of the sediment and physicochemical data. On the basis of the results of R-mode and Q-mode cluster analyses, several different biotopes can be defined as marsh biotope/near-marsh biotope; marginal urban/marginal urban mixing biotope; inner-outer lagoon biotope or enclosed lagoon; outer lagoon biotope, mixed sub-biotope; and outer lagoon, marine sub-biotope. These biotopes are related to foraminifera assemblages and substrate type and are influenced by local currents, water depth, chemical and physicochemical conditions, river or oceanic proximity, and anthropogenic impact, as evidenced by the mapping of the six factor loadings of the principal component analysis conducted herein. Based on a similar methodology of analysis as that applied in previous studies in the Lagoon of Venice, comparable biotypes were identified in Lagoon of Aveiro.

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

    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.

    This work analyses the distribution of heavy metals in the sediments of Ria de Aveiro (Portugal) assessed by total digestion and sequential chemical extraction of the sediments. The influence of environmental parameters on the living benthic foraminiferal assemblages was studied. The most polluted parts in the Ria de Aveiro are areas where the residence time is high and cohesive sediments are deposited. Organic matter, which is an excellent scavenger for a number of metals, is in general more abundant in the finer deposits of this lagoon, which act as sinks of anthropogenic pollutants. This condition is observed in Aveiro canals and Murtosa channel where sediments with the highest concentrations of Zn, Pb, Cu, and Cr are found. The sediments of Murtosa channel are also enriched in As, Co and Hg. In Aveiro canals the enrichment of heavy metals is mostly related to the past industrial production at their margins (ceramic and metallurgy), whereas in Murtosa channel with effluent discharges of the Chemical Complex of Estarreja. Foraminiferal density and diversity reach higher values near the lagoon mouth under higher marine influence and decline in general under very low-oxygen conditions. Some species seems to be indifferent to the increasing of TOC (e.g. Haynesina germanica and Ammonia tepida) and some have an opportunistic behaviour in areas with very depressed levels of oxygen (e.g. A. tepida and Quinqueloculina seminulum) whereas other species can better tolerate sulphide/reducing conditions (e.g. H. germanica, Bolivina ordinaria, Buliminella elegantissima, Bulimina elongata/gibba and Nonionella stella) a widespread condition in this lagoon. Foraminiferal density and some species are negatively correlated with concentrations of heavy metals. A most sensitive group of species to higher concentrations of heavy metals is identified (such as B. ordinaria, B. pseudoplicata and B. elongata/gibba) and another one of more tolerant species (such as H. germanica A. tepida

    Through the examination of a set of baptismal records from Aveiro, a coastal town between Lisbon and Porto in northern Portugal, this study explores the ways in which women were identified in relation to their families and community, and in relation to their economic occupations. The findings show that of the approximate 2,600 names of parents and godparents who were noted in the parish registers in the years between 1624 and 1638, the vast majority of them were not provided with a work label. Yet, the inconsistent manner in which women and men were identified suggests that what the church scribe deemed worthy of note did not necessarily reflect the views of the broader community. Although officialdom generally relegated women to their marital or family links, it was possible for a woman to acquire an occupational status of her own.

    Aveiro is a town with 80,000 inhabitants situated in the central west coast of Portugal. It is located at the centre of the Ria de Aveiro, a coastal lagoon that functions as a multi-estuarine area. This town is crossed by several canals which are connected with lagoon channels through canal locks. The operation of the canal locks influences the hydro dynamism in Aveiro's canal and this and other human activities have left a sedimentary record. The study of these records was based on the sediments grain size and composition, mineralogy (by XRD techniques), geochemical (by ICP-MS), total organic carbon (TOC), and microfaunal (benthic foraminifera) content in 15 grab-samples collected in 2006 in Aveiro's canal. The total elemental concentrations evaluated by total digestion of the sediment fraction <2000 μm revealed the presence of "hot spots" of pollution caused by heavy metal contaminants in some Aveiro canals, related to legacies of past industrial activities. These "hot spots" have, for instance, higher available concentrations of Al, Cd, Co, Cu, Fe, Pb, Mn and Zn (evaluated by sequential chemical extractions) and are located in Paraíso, Alboi, Botirões and Cojo Canals, at sites where the sediments are finer and richer in TOC. Abiotic and biotic variables submitted to principal component analysis and cluster analysis highlights the hydrodynamics and human effects on the system and the negative influence of pollutants on the benthic organisms (foraminifera).

    A decrease in the areas covered by seagrasses within the Ria de Aveiro, Portugal, has been observed over the past five decades, resulting in a corresponding increase of the areas of uncovered sediment supporting the growth of sparse macroalgae populations only. Presently, several macroalgae ( Ulva spp., Gracilaria sp.) and one seagrass species ( Nanozostera noltii (Hornem.) Toml. & Posl.) comprise the submerged aquatic vegetation (SAV) adapted to this shallow, high-energy environment, characterised by fast tidal currents and turbid waters and in which large areas of the bed are exposed during low tide. This study shows that there is a strong inter-relation between the SAV and the surface sediment in intertidal areas. The sediment covered by N. noltii was finer (median grain size 95 µm) and had a high percentage of organic matter (mean value 7.6%), compared with the sediment colonised by macroalgae (median grain size 239 µm; mean organic content 3.2%). The concentrations of both total nitrogen and phosphorous were significantly greater ( P < 0.001) in surface sediments covered by N. noltii. Thus, sediments within N. noltii appear to act as a large reservoir of N and P by accumulating greater concentrations of fine sediment particles (silt and clay) and organic matter when compared with the coarser sediment covered with macroalgae only. Hence, the reduction in the area covered by seagrasses will likely result in a gradual loss of nutrients and fine sediment from the Ria de Aveiro channels.

    In this study, the DNA integrity of golden grey mullet (Liza aurata) collected in differently contaminated sites of a coastal lagoon, Ria de Aveiro (Portugal), was assessed, over the period of 1 year, using the DNA alkaline unwinding assay, in four different tissues (gill, kidney, liver and blood) and compared to a reference site. The four tissues displayed different DNA integrity basal levels, clearly affected by seasonal factors. Gill and kidney were, respectively, the most and least sensitive tissues. All sites demonstrated the capacity to interfere with DNA integrity. The sites displaying the highest and lowest DNA damage capability were, respectively, Barra (subject to naval traffic) and Vagos (contaminated with polycyclic aromatic hydrocarbons). In terms of seasonal variability, autumn seems to be the more critical season (more DNA damage) unlike summer when no DNA damage was found in any tissue. Data recommend the continued monitoring of this aquatic system.

    This work aims to assess the trematode parasites infecting the edible cockle Cerastoderma edule, collected in the Ria de Aveiro lagoon, one of the most relevant biodiversity hotspots of the Western Iberia, and evaluate the relationship between the observed patterns and environmental descriptors. A total of 11 of the 16 trematode species known to infect C. edule were identified, including Himasthla continua and Psilostomum brevicolle as new occurrences in this lagoon. Parvatrema minutum was the most abundant and dominant species. Species richness and prevalence were high. The relationship between trematode species abundance, intensity and prevalence, and also environmental variables, showed that most parasites preferred muddy sand areas with euhaline conditions in opposition to areas with contamination and/or distant from the lagoon entrance. This study highlighted the good ecological status of the ecosystem and the transitional biogeographic characteristics of the western Portuguese coast where northern and subtropical faunas can coexist.

    The dominance of a plant species in highly metal-contaminated areas reflects its tolerance or adaptability potential to these scenarios. Hence, plants with high adaptability and/or tolerance to exceptionally high metal-contaminated scenarios may help protect environmental degradation. The present study aimed to assess the strategies adopted by common reed, Phragmites australis for its dominance in highly mercury-contaminated Ria de Aveiro coastal lagoon (Portugal). Both plant samples and the sediments vegetated by monospecific stand of Phragmites australis were collected in five replicates from mercury-free (reference) and contaminated sites during low tide between March 2006 and January 2007. The sediments’ physico-chemical traits, plant dry mass, uptake, partitioning, and transfer of mercury were evaluated during growing season (spring, summer, autumn, and winter) of P. australis. Redox potential and pH of the sediment around roots were measured in situ using a WTW-pH 330i meter. Dried sediments were incinerated for 4 h at 500°C for the estimation of organic matter whereas plant samples were oven-dried at 60°C till constant weight for plant dry mass determination. Mercury concentrations in sediments and plant parts were determined by atomic absorption spectrometry with thermal decomposition, using an advanced mercury analyzer (LECO 254) and maintaining the accuracy and precision of the analytical methodologies. In addition, mercury bioaccumulation and translocation factors were also determined to differentiate the accumulation of mercury and its subsequent translocation to plant parts in P. australis. P. australis root exhibited the highest mercury accumulation followed by rhizome and leaves during the reproductive phase (autumn). During the same phase, P. australis exhibited ≈5 times less mercury-translocation factor (0.03 in leaf) when compared with the highest mercury bioaccumulation factor for root (0.14). Moreover, seasonal variations differentially

    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 present work aimed to investigate golden grey mullet (Liza aurata) liver protection versus damage responses at a polluted coastal lagoon, Ria de Aveiro (Portugal), as a tool to evaluate the human impacts on environmental health at five critical sites in Ria de Aveiro (Portugal) in comparison to a reference site (Torreira; TOR). Protection was evaluated by measuring non-enzymatic [total glutathione (GSHt) and non-protein thiols (NPT)] and enzymatic [catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST), and glutathione reductase (GR)] antioxidant defenses. Damage was assessed as DNA integrity loss and lipid peroxidation (LPO). No significant differences were found between sites in terms of non-enzymatic defenses (GSHt and NPT). CAT did not display significant differences among sites. However, GPx at Barra (BAR, associated with naval traffic), Gafanha (GAF, harbor and dry-dock activities area), Laranjo (LAR, metal contaminated associated with chlor-alkali plant), and Vagos (VAG, contaminated by polycyclic aromatic hydrocarbons) was significantly lower than the reference site. GST was lower at GAF, Rio Novo do Príncipe (RIO, pulp mill effluent area), LAR, and VAG, whereas GR was lower at RIO. The loss of antioxidant defenses was paralleled by higher LPO levels only at GAF and VAG. However, no DNA integrity loss was found. Results highlight the importance of the adopted multibiomarkers as applied in the liver of L. aurata in coastal water pollution monitoring. The integration of liver antioxidant defense and damage responses can improve the aquatic contamination assessment.

    The sedimentary unconsolidated cover of the Aveiro-Espinho continental shelf and upper slope (NW Portugal) records a complex interplay of processes including wave energy and currents, fluvial input, sediment transport alongshore and cross-shelf, geological and oceanographic processes and sediment sources and sinks. In order to study this record, a set of surface sediment samples was studied. Sediment grain size and composition, as well as the mineralogical composition (by XRD) of the fine (< 63 μm) and clay (< 2 μm) fractions and benthic microfaunal (foraminifera) data were analysed. Cluster analysis applied to the sedimentological data (grain size, sediment composition and mineralogy) allowed the establishment of three main zones corresponding to the: inner-, mid- and outer-shelf/upper slope. On the inner-shelf, the sedimentary coverture is composed of siliciclastic fine to very fine sand, essentially comprising modern (immature) terrigenous particles. The sediment grain size, as well as mineralogical and microfaunal composition, denote the high energetic conditions of this sector in which the alongshore transport of sand is predominantly southward and occurs mostly during the spring-summer oceanographic regime, when the main river providing sediments to this area, the River Douro, undergoes periods of drought. This effect may emphasize the erosive character of this coastal sector at present, since the Ria de Aveiro provides the shelf with few sediments. On the mid-shelf, an alongshore siliciclastic band of coarse sand and gravel can be found between the 40 m and 60 m isobaths. This gravelly deposit includes relic sediments deposited during lower sea-level stands. This structure stays on the surface due to the high bottom energy, which promotes the remobilization of the fine-grained sediments, and/or events of sediments bypassing. Benthic foraminifera density and "Benthic Foraminifera High Productivity" (BFHP) proxy values are in general low, which is consistent

    Methane is a powerful greenhouse gas and an important energy source. The global significance and impact in coastal zones of methane gas accumulation and seepage in sediments from coastal lagoon environments are still largely unknown. This paper presents results from four high-resolution seismic surveys carried out in the Ria de Aveiro barrier lagoon (Portugal) in 1999, 2002 and 2003. These comprise three chirp surveys (RIAV99, RIAV02, RIAV02A) and one boomer survey (RIAV03). Evidence of extensive gas accumulation and seepage in tidal channel sediments from the Ria de Aveiro barrier lagoon is presented here for the first time. This evidence includes: acoustic turbidity, enhanced reflections, acoustic blanking, domes, and acoustic plumes in the water column (flares). The stratigraphy and structural framework control the distribution and extent of gas accumulations and seepage in the study area. In these shallow systems, however, tidal altitude variations have a significant impact on gas detection using acoustic methods, by changing the raw amplitude of the enhanced seismic reflections, acoustic turbidity, and acoustic blanking in gas-prone areas. Direct evidence of gas escape from drill holes in the surrounding area has shown that the gas present in the Ria de Aveiro consists of biogenic methane. Most of the gas in the study area was probably generated mainly in Holocene lagoon sediments. Evidence of faults affecting the Mesozoic limestones and clays underlying some of the shallow gas occurrences, and the presence of high-amplitude reflections in these deeper units raise the possibility that some of this gas could have been generated in deeper sedimentary layers, and then migrated upward through the fractured Mesozoic strata.

    Fish gill importance in toxicants uptake, bioconcentration and excretion allied to meagre knowledge on branchial damage/protection responses substantiate this study. Five critical sites in Ria de Aveiro (Portugal) were assessed in comparison with a reference site (Torreira), focusing on Liza aurata gill antioxidant defences versus damage (oxidative and genetic). Only in Barra fish displayed damage (lipid peroxidation) though no differences were found in antioxidants. In all other sites, except Rio, antioxidant alterations were found. Thus, fish from Gafanha, Laranjo and Vagos showed higher total glutathione, glutathione peroxidase and catalase. Higher glutathione reductase and glutathione S-transferase activity was also found in the first and the last sites, respectively. In Laranjo, metallothionein levels were higher though lower in Gafanha and Vagos. In general, damage was not accompanied by defences weakening confirming that predicting damage based on antioxidants depletion is not straightforward. The integrated biomarker response index ranked sites as: Gafanha>Barra>Laranjo>Vagos>Rio>Torreira.

    Hepatitis A is a common viral liver disease and brings serious health and economic problems as its epidemiologic pattern changes over time. National serosurveys from developed countries have indicated a decline in HAV (hepatitis A virus) seroprevalence over time due to the improvement of economic and sanitation levels. The hepatitis A virus (HAV) immunity rate was surveyed throughout an eleven-year period by sex and age group in Aveiro District. In this retrospective study, blood samples from patients of Aveiro District, in ambulatory regime, collected at the Clinical Analysis Laboratory Avelab between 2002 and 2012 were screened for the presence of antibodies against HAV antigen using a chemiluminescence immunoassay. The global immunity (positive total anti-HAV) was 60% and only 0.3% of the patients presented recent infection by HAV (positive IgM anti-HAV). The HAV immunity was age-dependent (p < 0.05), but no significant differences (p > 0.05) between sexes were observed. The immunity was similar throughout the study period (p > 0.05). The results of this study indicate that young people (especially under 25 years old) from District of Aveiro are susceptible to HAV infection, constituting a high risk group. The elderly should be also a concern in the future of Hepatitis A infection.

    Organotin compounds are used in a variety of industrial processes therefore their subsequent discharge into the environment is widespread. Bacteria play an important role in biogeochemical transformations acting as natural decontamination agents. Therefore, screening for tributyltin (TBT)-resistant and -degrading bacteria is relevant for the selection of isolates with decontamination ability of these polluted areas. With this purpose, 50 strains were isolated from sediment and water from Ria de Aveiro and their tolerance to TBT, up to 3mM, was evaluated. Generally, occurrence of highly TBT-resistant bacteria was observed, and Gram negative bacteria exhibited more tolerance to TBT than Gram positive bacteria. A memory response was observed when bacteria were progressively exposed to increasingly higher TBT concentrations. One isolate, Aeromonas veronii Av27, highly resistant to TBT (3mM) uses this compound as carbon source and degrades it to less toxic compounds.

    Data on fecundity of Corophium multisetosum from Areão (Ria de Aveiro, Portugal) are analysed by non linear regression to quantify the relationship between brood size (N(e)) and head length (L(h), in mm), water temperature (T, in degrees Celsius) and salinity (S, in psu). The aim of the analysis is to obtain a simple line N(e)=a+bL(h), in which the slope (b) and the y intercept (a) are functions of salinity and/or temperature on each sampling occasion. The equation N(e)=(-2.940-8.027S)+(-89.431+18.171S+12.904T-0.368T(2))L(h) explains 64% of the variability of brood size throughout the breeding period. The model predicts an optimal temperature around 18 degrees C and a very low fecundity at low salinities. The graphical comparison of the lines obtained by the model and by a usual linear regression illustrates its potential usefulness to predict fecundity changes. The authors suggest that the observed variation in the fecundity of other brackish-water amphipods can be described and predicted using similar models.

    Ria de Aveiro is a mesotidal coastal lagoon with one of the largest continuous salt marshes in Europe. The objective of this work was to assess C, N and P stocks of Spartina maritima (low marsh pioneer halophyte) and Juncus maritimus (representative of mid-high marsh halophytes) combined with the contribution of Halimione portulacoides, Sarcocornia perennis, and Bolbochenous maritimus to the lagoon ≈4400 ha marsh area. A multivariate analysis (PCO), taking into account environmental variables and the annual biomass and nutrient dynamics, showed that there are no clear seasonal or spatial differences within low or mid-high marshes, but clearly separates J. maritimus and S. maritima marshes. Calculations of C, N and P stocks in the biomass of the five most representative halophytes plus the respective rhizosediment (25 cm depth), and taking into account their relative coverage, represents 252053 Mg C, 38100 Mg N and 7563 Mg P. Over 90% of the stocks are found within mid-high marshes. This work shows the importance of this lagoon’s salt marshes on climate and nutrients regulation, and defines the current condition concerning the ‘blue carbon’ and nutrient stocks, as a basis for prospective future scenarios of salt marsh degradation or loss, namely under SLR context.

    Efficient and sustainable management of rapidly mounting environmental issues has been the focus of current intensive research. The present study aimed to investigate the impact of plant phenological development stage variation on mercury (Hg) tolerance, accumulation, and allocation in two salt marsh macrophytes Triglochin maritima and Scirpus maritimus prevalent in historically Hg-contaminated Ria de Aveiro coastal lagoon (Portugal). Both plant samples and the sediments vegetated by monospecific stands of T. maritima and S. maritimus were collected from reference (R) and sites with moderate (M) and high (H) Hg contamination in Laranjo bay within Ria de Aveiro lagoon. Hg tolerance, uptake, and allocation in T. maritima and S. maritimus, physico-chemical traits (pH, redox potential, and organic matter content) and Hg concentrations in sediments vegetated by these species were impacted differentially by phenological development stages variation irrespective of the Hg contamination level. In T. maritima, Hg concentration increased with increase in Hg contamination gradient where root displayed significantly higher Hg followed by rhizome and leaf maximally at H. However, in S. maritimus, the highest Hg concentration was perceptible in rhizome followed by root maximally at M. Between the two studied plant species, S. maritimus displayed higher Hg tolerance index (depicted by higher plant dry mass allocated to reproductive stage) and higher available Hg at M (during all growth stages) and H (during senescent stage) when compared to T. maritimus. Both plant species proved to be Hg excluder (low root/rhizome-leaf Hg translocation). Additionally, T. maritima also acted as Hg stabilizer while, S. maritimus as Hg accumulator. It can be inferred from the study that (a) the plant phenological development stage variations significantly influenced plant Hg sensitivity by impacting sediment chemistry, plant growth (in terms of plant dry mass), Hg accumulation, and its subsequent

    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.

    A new outbreak of human diarrhoeic poisonings (DSP) with esters of okadaic acid (OA) was confirmed after ingestion of razor clams (Solen marginatus) harvested at Aveiro lagoon (NW Portugal) in the summer of 2001. Accumulation of marine toxins in second order consumers was investigated in the edible parts of a shellfish predator abundant at Aveiro lagoon, the green crab Carcinus maenas. Okadaic acid was found, also in a predominant esterified form. Levels in edible parts (comprising mainly viscera) surpassed 16microg/100g. We suggest that one patient may have developed profuse diarrhoea after ingestion of a large number of green crabs contaminated with okadaic acid esters. At least 32microg OA/100g were found in a remaining sample of its meal. Domoic acid was also found but under the allowable level in force in USA of 30microg/g crab viscera. In cooked crabs, significant losses of domoic acid were found and it is not suspected to have contributed to the poisoning event, although being a vector for this toxin. The low percentage of free okadaic acid found is in accordance with a predation predominantly on benthonic shellfish (razor clams, clams and common cockle) rather than on rock mussels. These last ones present usually higher percentages of free okadaic acid. Okadaic acid was confirmed with full-scan mass spectra either in plankton and mussel extracts. Okadaic acid esters were also found in plankton extracts. Percentages between 40-60% of esterified OA were found in samples freshly extracted. Ester's percentage diminished drastically if after sonication the extract was kept at room temperature. The major part of the esters was water-soluble.

    In the scope of the first WDF management cycle, a multi-municipality sanitation system with secondary treatment was implemented in 2005 in Ria de Aveiro coastal lagoon, with the treated effluent discharging into the Atlantic Ocean through a submarine outfall. The lagoon water chemical status was evaluated regarding dissolved inorganic nutrients and chlorophyll a before and after 2005. The S. Jacinto outfall has effectively reduced the point source nutrient loads (ammonium and phosphate) into Ria de Aveiro, representing a step forward for the implementation of the WFD, through eutrophication abatement. However, the lagoon remains exposed to non-point nitrogen sources, as a consequence of the current land use and water management, which in a scenario of winter extreme precipitation events, nutrients increase through surface run-off. Besides, in a combined scenario of low freshwater input into the lagoon and favourable oceanic condition, nutrients enter through Ria outer boundary coming from the S. Jacinto outfall. Thus, changes in the system hydrodynamics in the context of global change might pose new challenges regarding the WFD second management cycle involving the second river basin management plan and the first flood risk management plan, foreseeing the 'Good' ecological status in all Ria's Water Bodies.

    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 mean sea level rising is an important consequence of climate change because of its impact on society and coastal ecosystems. Tide gauge information evidences that global mean sea level has increased in the 20th century, and it is expected that its rise will continue during the 21th century. However, the sea levels are not changing uniformly around the world, as both tide gauge and satellite data confirm. Sea level rise can have a wide variety of impacts on worldwide coastal areas, causing flooding, land loss, the salinization of groundwater and the destruction of built property and infrastructures. In Portugal, the region's most affected by the sea level rise are probably the Aveiro and Formosa coastal lagoons as well as the Tagus and Sado estuaries. A good understanding of the sea level rise influence in the estuarine tidal dynamics is crucial to mitigate these problems. However, the response of each coastal region to sea level rise depends on the physical features of the coastal system, and therefore their effects should be locally assessed. Thus, this work aims to investigate the potential impacts of the mean sea level rise in coastal regions, analysing the particular case of Ria de Aveiro, which is in risk of flooding. To assess these changes the numerical model Mohid was implemented in Ria de Aveiro. Mohid is a finite volume model, designed for coastal and estuarine shallow water applications. Although Mohid is a 3D baroclinic model, it was used herein in baratropic mode with a single vertical layer, considering that due to its shallow depths, Ria de Aveiro circulation can be simulated with a depth integrated model. The model was used initially to characterize the lagoons hydrodynamic under the actual sea level, through the determination of the amplitude and phase of the main tidal constituents, maximum levels and velocities, tidal asymmetry, as well as the tidal prism in the main sections of the lagoon. After, a realistic regional sea level rise scenario

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

    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 the dominant species ( Enteromorpha, Fucus and Gracilaria). Total mercury in the plant tissues ranged from 0.02 to 2.1 μg g -1 dwt. Fucus was the most contaminated algae, followed by Gracilaria and Enteromorpha. As a whole, organic mercury never exceeded 15% of total mercury content, but tended to increase with distance to metal source on all macroalgae indicating complex physiological responses from these primary producers in areas of high and low mercury concentrations. Sessile macroalgae may be important mercury immobilisation agents, while free-floating algae ( Enteromorpha) play an important role in mercury transport from contaminated areas (±10 g ha -1) to other areas of the lagoon and even to coastal waters. Based on the present results the use of macroalgal biomass from contaminated areas for direct or indirect human use (e.g. agricultural, industrial and food purposes) may result in health risks, due to the high bioaccumulation capacity (as high as 10 4 the dissolved mercury concentrations).

    The present study aims to evaluate the predominance of uropathogens responsible for urinary tract infection (UTI) and determine their resistance patterns, to assess if the recommended empirical treatment is appropriate for the studied population. Samples were collected in Aveiro (Portugal) from an ambulatory service between June 2011 and June 2014. From the 4,270 positive urine samples for UTI, 3,561 (83%) were from women and only 709 (17%) were from men. The bacterium Escherichia coli was the most frequent uropathogen, followed by Klebsiella sp., Enterococcus sp., and Proteus mirabilis. E. coli was also the uropathogen presenting less resistance to antibiotics, including those recommended as first and second line UTI treatment. In general, bacteria isolated from men were more resistant to antimicrobials than bacteria isolated from women. The results of this study emphasized the relevance to consider sex as a differentiating factor in the choice of UTI empirical treatment, mainly due to differences in antimicrobial resistance. From the first line drugs recommended by the European Association of Urology (EAU) to empirical treatment of uncomplicated UTI, nitrofurantoin is the most appropriate drug for both sexes. Ciprofloxacin, although appropriate for treatment in women, is not appropriate to treat UTIs in men. From the second line drugs, both trimethoprim-sulfamethoxazole (TMP-SMX) and amoxicillin-clavulanic acid (AMX-CA) are appropriate drugs for treatment of uncomplicated UTI in women, but not as effective for men.

    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.

    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.

  4. Moral actor, selfish agent.

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

    The influence of salt marsh on estuarine bacterioplankton was investigated in two estuaries with different hydrodynamic characteristics (Ria de Aveiro and Tagus Estuary). In the Ria de Aveiro, bacteria in the flood water overlying the marsh were two times more abundant and five to six times more active than in the main channel. In the Tagus Estuary, bacterial abundance was similar in flooding and channel water, but bacterial activity was up to two times higher in the main channel. The two salt marshes have distinct influences on estuarine bacterioplankton abundance and activity. In the Ria de Aveiro, salt marsh enhanced estuarine bacterial communities, increasing their size and stimulating their activity. By contrast, the salt marsh in the Tagus Estuary does not seem to increase the bacterial abundance and production in the channel water. These distinct influences may be explained by the hydrodynamic characteristics of the salt marshes, which were confirmed by the hydrodynamic model implemented for both systems.

    The main objective of this paper was to evaluate the impact of mercury on the zooplankton communities' structure and functioning and their bioaccumulation patterns along a contamination gradient in a temperate coastal lagoon. Our results demonstrated that total abundance was not negatively affected by Hg contamination, since the most contaminated areas presented the highest values, being the copepod Acartia tonsa the dominant species, which means that it is a very well adapted and tolerant species to mercury. Nevertheless, negative effects were observed in terms of species diversity, since the most contaminated areas presented the lowest values of species richness, evenness and heterogeneity. Moreover, the spatial mercury gradient was reflected on the bioaccumulation patterns of the zooplankton communities. This reinforces the idea that zooplankton can be considered as an important vehicle of mercury transfer through the food pelagic web since it constitutes a primordial food resource for several commercial fish species.

    During the last decades, achieving water efficiency in buildings has increasingly become an important challenge in the scope of sustainability. Water consumption is directly related to individual conduct. Despite the various technological improvements in fixtures and appliances, their performance will be influenced by human preferences and behavior. As a result, the potential for effective water consumption saving is influenced by behavior change as well as water-efficient fixtures and appliances. This work evaluates the impact of user preferences and behavior change on the water-efficient performance of tap aerators in a case study building: the Department of Civil Engineering building of the University of Aveiro, Portugal. Four aerators with different discharge reductions and types were installed in the toilet's washbasins and the user's preferences and behavior change measured through direct and online questionnaires. It was observed that the effective water consumption reduction (15 to 49%) was less than the discharge reduction (30 to 70%), confirming that user factors influence water savings. Water use reductions in the tested range (2.0 to 6.7 l/min) also varied according to gender, with male users using less water than their female counterparts. It was noted that an awareness of sustainability values prevailed amongst the users when confronted with the choice between comfort and water efficiency, although differences were observed in the user preferences regarding the various aerators. When confronted with the information that the lower discharge aerator would contribute to a reduction of about 70% on the water discharge, 25% of the users agreed with its use, even if it resulted in a certain degree of dissatisfaction. In comparison, only 8% of the users completely disagreed with its installation. On average, the water consumption reduction was 46% smaller than the discharge reduction achievable with the aerator alone. This further confirms the user factors

    The influence of photochemical transformations of chromophoric dissolved organic matter (CDOM) on microbial communities was evaluated in the estuarine system Ria de Aveiro. Two sites, representative of the marine and brackish water zones of the estuary, were surveyed regularly in order to determine seasonal and vertical profiles of variation of CDOM properties. Optical parameters of CDOM indicative of aromaticity and molecular weight were used to establish CDOM sources, and microbial abundance and activity was characterized. Additionally, microcosm experiments were performed in order to simulate photochemical reactions of CDOM and to evaluate microbial responses to light-induced changes in CDOM composition. The CDOM of the two estuarine zones showed different spectral characteristics, with significantly higher values of the specific ultra-violet absorbance at 254 nm (SUVA254) (5.5 times) and of the absorption coefficient at 350 nm (a350) (12 times) and lower SR (S275-295/S350-400) ratio at brackish water compared with the marine zone, reflecting the different amounts and prevailing sources of organic matter, as well as distinct riverine and oceanic influences. At the marine zone, the abundance of bacteria and the activity of Leu-AMPase correlated with a350 and a254, suggesting a microbial contribution to the HMW CDOM pool. The irradiation of DOM resulted in a decrease of the values of a254 and a350 and an increase of the slope S275-295 and of the ratios E2 : E3 (a250/a365) and SR, which in turn increase its bioavailability. However, the extent of photoinduced transformations and microbial responses was dependent on the initial optical characteristics of CDOM. In Ria de Aveiro both photochemical and microbial processes yielded optical changes in CDOM and the overall results of these combined processes determine the fate of CDOM in the estuarine system and have an influence on local productivity and in adjacent coastal areas.

    The pharmaceutical industry is one of the most tightly regulated sectors, and it is essential to know each country׳s legal framework to understand the regulation, approval, and marketing of medicinal products for human use. This article describes the main statutes and procedures governing medicinal products for human use in Portugal and the role of the country׳s National Medicines and Health Products Authority (Autoridade Nacional do Medicamento e Produtos de Saúde, I.P.; INFARMED). From the most recently available data, an update of requests and approvals concerning marketing authorizations, variations, pricing, and reimbursements is provided. Data were sourced from the INFARMED website, Infomed (database of medicinal products for human use), and periodic reports issued by national authorities. Organic laws, acts, and law decrees published in the government gazette (Diário da República) are cited and reproduced as required. In 2015 Portugal ranked fifth in the European System of Medicines Evaluation in terms of the number of completed procedures as a reference member state. Approximately 80% of all approved drug applications in Portugal in 2015 were for generic drugs, mostly pertaining to the nervous system. In Portugal, INFARMED monitors drug quality, safety profile, and efficacy in all stages of the drug life cycle, ensuring patients' safety. The Portuguese market for medicinal products for human use has been appreciably changed by the advent of generic drugs. There is an increased trend for new request applications for biological and biotechnological substances. Copyright © 2016 Elsevier HS Journals, Inc. All rights reserved.

    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.

    This study compared actors', partners', and observers' perceptions of the amount of sarcasm used by participants (n = 80) in videotaped conversations. Significant differences were found among perceptions of actors, partners, and observers. Of the three perspectives, actors perceived themselves as using the greatest amount of sarcasm, followed by partners' perceptions of actors. Observers perceived actors as using the least amount of sarcasm. Correlations conducted to assess whether partners and observers recognized actors' individual attempts at sarcasm during the conversations were generally low.

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

    2017-01-01

    The actor nodes are the spine of wireless sensor and actor networks (WSANs) that collaborate to perform a specific task in an unverified and uneven environment. Thus, there is a possibility of high failure rate in such unfriendly scenarios due to several factors such as power consumption of devices, electronic circuit failure, software errors in nodes or physical impairment of the actor nodes and inter-actor connectivity problem. Therefore, it is extremely important to discover the failure of a cut-vertex actor and network-disjoint in order to improve the Quality-of-Service (QoS). In this paper, we propose an Efficient Actor Recovery (EAR) paradigm to guarantee the contention-free traffic-forwarding capacity. The EAR paradigm consists of a Node Monitoring and Critical Node Detection (NMCND) algorithm that monitors the activities of the nodes to determine the critical node. In addition, it replaces the critical node with backup node prior to complete node-failure which helps balancing the network performance. The packets are handled using Network Integration and Message Forwarding (NIMF) algorithm that determines the source of forwarding the packets; either from actor or sensor. This decision-making capability of the algorithm controls the packet forwarding rate to maintain the network for a longer time. Furthermore, for handling the proper routing strategy, Priority-Based Routing for Node Failure Avoidance (PRNFA) algorithm is deployed to decide the priority of the packets to be forwarded based on the significance of information available in the packet. To validate the effectiveness of the proposed EAR paradigm, the proposed algorithms were tested using OMNET++ simulation. PMID:28420102

    Portugal has experienced rapid decline of neonatal and infant mortality in the last century, similar to that of other western European states. The joint venture of pediatricians and obstetricians with adequate top-down government commissions for maternal and child health for the decision making by health administrators and a well-defined schedule of preventive and managerial measures in the community and in hospitals are the most likely explanations for this success. Another achievement of child health care services is the registry for special diseases. Education of health care workers plays a fundamental role in improving health statistics. Portugal has a reasonable number of doctors, nurses, and health technicians per capita. Quality assurance monitoring systems and implementation of evidence-based clinical guidelines with digital records, including international coding, are essential steps to improve health care systems.

Much of the data was summarized in tables and illustrated on maps, enabling the community of clinicians, researchers, and patient organizations to access the knowledge about the research performed. This study provides an overview about the distribution of aeroallergens in Portugal, signaling regions and critical periods of exposure of the sensitized population. The illustrated data can help the community of allergy specialists to view the temporal and spatial distribution of aeroallergens across the country. In addition, this information can guide clinicians to select the most appropriate allergens for allergy diagnostic testing, treatment, and allergen avoidance.

  15. Tornadoes in Portugal

    NASA Astrophysics Data System (ADS)

    Leitão, Paula

    In Portugal, research on tornadoes is very recent and has shown that they are not as rare as it is believed by public and even by scientific opinion. As tornadoes only affect a small area, the probability of their being observed at a meteorological station is very small. Thus, most of the existing records are people's recollections, some description in newspapers and some photos. It was possible to find data on 30 tornadoes that occurred from 1936 to 2002. This number is undoubtedly underestimated because the database is always under construction. Those tornadoes were moderate to strongly devastating, some of them causing great damage. The strongest tornado in Portugal, a T7 event, happened in November 1954. The less intense tornadoes are, for sure, underestimated. After the year 2000, a more careful look for reports reveals the existence of some weak tornadoes. Tornadoes occur mainly from October to January in association with strong cold fronts or line squalls. Most cases were in association with deep extratropical cyclones west of Portugal, when there was a moist and warm south-west strong to gale-force flow and a generalised severe weather over the country. Some cases happened in a very unstable westerly flow. There are also records on summer tornadoes, developing from strong thunderstorm cells. Often, such thunderstorms are mesoscale convective systems resulting from strong heating of the centre of the Iberian Peninsula.

    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

    Familial hypercholesterolaemia (FH) is characterised clinically by an increased level of circulating LDL cholesterol that leads to lipid accumulation in tendons and arteries, premature atherosclerosis and increased risk of coronary heart disease (CHD). Although Portugal should have about 20,000 cases, this disease is severely under-diagnosed in our country, this being the first presentation of Portuguese data on FH. A total of 602 blood samples were collected from 184 index patients and 418 relatives from several centres throughout Portugal. Fifty-three different mutations were found in 83 index patients, 79 heterozygous and 4 with two defective LDLR alleles. Additionally, 4 putative alterations were found in 8 patients but were not considered mutations causing disease, mainly because they did not co-segregate with hypercholesterolaemia in the families. Three unrelated patients were found to be heterozygous for the APOB(3500) mutation and two unrelated patients were found to be heterozygous for a novel mutation in PCSK9, predicted to cause a single amino acid substitution, D374H. Cascade screening increased the number of FH patients identified genetically to 204. The newly identified FH patients are now receiving counselling and treatment based on the genetic diagnosis. The early identification of FH patients can increase their life expectancy and quality of life by preventing the development of premature CHD if patients receive appropriate pharmacological treatment.

    The renewed interest in mycology has been reflected in growing use of wild mushrooms in culinary, driven by its nutritional, organoleptic and commercial value. However, the international scientific literature describes several syndromes of poisoning by mushrooms. We live, therefore, a paradigm conducive to an increase of mycetism, whose diagnosis requires a high level of suspicion and knowledge of clinical profiles. In Portugal, the real dimension of this problem is unknown. Although some mycetisms, such as the hepatotoxic syndrome, have high morbidity and mortality, their relative incidences are unknown. Add up to the shortage of international scientific literature, often outdated and inappropriate to clinical practice. In this context, this article provides an updated epidemiological and clinical perspective emphasizing a narrative and descriptive information on the forms of presentation, differential diagnosis and therapeutic approach, with the ultimate goal of the elaboration of a national diagram-oriented approach to decision-making diagnosis. We analyzed all the clinical records of patients admitted into ten hospitals between 1990 and 2008, notified with the code 988.1 of GDH (acute poisoning by mushrooms). There were registered demographic data, way of presentation, time between ingestion and onset of symptoms, the annual distribution, clinical profile, clinical and analytical treatment performed and complications. We identified 93 cases of acute poisoning by mushrooms, with equal gender distribution and inclusion of individuals of all age groups (from 1 to 85 years), but with greater representation from 21 to 50 years. There was a bimodal seasonal pattern, with a higher peak between September and December and a second in the spring. The hepatotoxic profile presentation corresponded to 63.4% and 31.7% of the cases to gastroenteritis syndrome. The mortality in cases of hepatotoxicity was 11.8%.

    This analysis of the Portuguese health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Overall health indicators such as life expectancy at birth and at age 65 years have shown a notable improvement over the last decades. However, these improvements have not been followed at the same pace by other important dimensions of health: child poverty and its consequences, mental health and quality of life after 65. Health inequalities remain a general problem in the country. All residents in Portugal have access to health care provided by the National Health Service (NHS), financed mainly through taxation. Out-of-pocket payments have been increasing over time, not only co-payments, but particularly direct payments for private outpatient consultations, examinations and pharmaceuticals. The level of cost-sharing is highest for pharmaceutical products. Between one-fifth and one-quarter of the population has a second (or more) layer of health insurance coverage through health subsystems (for specific sectors or occupations) and voluntary health insurance (VHI). VHI coverage varies between schemes, with basic schemes covering a basic package of services, whereas more expensive schemes cover a broader set of services, including higher ceilings of health care expenses. Health care delivery is by both public and private providers. Public provision is predominant in primary care and hospital care, with a gate-keeping system in place for access to hospital care. Pharmaceutical products, diagnostic technologies and private practice by physicians constitute the bulk of private health care provision. In May 2011, the economic crisis led Portugal to sign a Memorandum of Understanding with the International Monetary Fund, the European Commission and the European Central Bank, in exchange for a loan of 78 billion euros.

    1995-12-31

    The total mercury content in samples of the brine shrimp Artemia, sediments, water, suspended matter and, when available, algae, from nine salines of Portugal, was evaluated, to find out how mercury present in its natural habitat accumulates in Artemia. This study, carried out between 1990 and 1993, was part of a larger research project aiming to contribute to the knowledge on mercury accumulation and its effects on Artemia. This crustacean is used worldwide for marine species feeding in aquafarms, including in Portugal. The following sampling sites were chosen: some salinas of the lagoon of Aveiro, situated in the northern region of Portugal and partially contaminated with mercury-, the salt-mines of Rio Maior, in the interior of the central region of the country, where there are no sediments (the floor is cemented); and salt-marshes in the Algarve, in the south of Portugal. Mercury was determined by cold vapor absorption espectrofotometry after digestion of samples with sulfuric acid and potassium permanganate, and reference materials have been used to control the analytical performance. The concentrations of total Hg varied from 0.014 to 0.36 mg/Kg in the sediments, 0 to 0.30 {micro}g/g in the Artemia, 0.17 to 0.84 {micro}g/l in the suspended matter and 0.09 to 0.56 {micro}g/l in the water. The content of mercury in the artemias was strongly related to the concentration in the sediments, except when the algae were present, because they also accumulate a significantly percentage of the mercury. No relationships could be established with the Hg in water or in suspended matter (in mass of Hg/volume of filtered water), because their, content in Hg varied a lot with time and weather conditions, such as the wind strength. The presence of Hg in the sediments was due either to significant containing Hg discharges or to the composition of the sediments, being more important in the case of clays.

  12. On the question of homosexuality in actors.

    PubMed

    Neuringer, C

    1989-12-01

    There is a belief that a high percentage of male actors are homosexual. The specific linking of actors and homosexuality seems to have first appeared in the Elizabethan Puritan condemnations of the theater. Psychoanalytic theory has tended to further promulgate the linkage between effeminacy, homosexuality, and acting. An analysis of the relevant existing empirical literature indicates that few studies have addressed themselves to evaluating this relationship. Those studies supporting the effeminacy-actor relationship were seriously flawed both in design (e.g., use of indirect measures to infer homosexuality) and interpretation of the data. Only one study used direct measures of sexual orientation. Even though that study had methodological problems, its results indicated that the percentage of homosexuality among actors was not verifiably greater than that found in the general population. It is felt that the current belief of greater homosexuality in actors, as compared to the general population, is a product of our Puritan heritage, the actor's unconventionality, and of public flaunting of the homoerotic behavior of that portion of actors that are homosexual.

    Lone-actor terrorist attacks have risen to the forefront of the public's consciousness in the past few years. Some of these attacks were conducted against public officials. The rise of hard-to-detect, low-tech attacks may lead to more public officials being targeted. This paper explores whether different behavioral traits are apparent within a sample of lone-actor terrorists who plotted against high-value targets (including public officials) than within a sample of lone actors who plotted against members of the public. Utilizing a unique dataset of 111 lone-actor terrorists, we test a series of hypotheses related to attack capability and operational security. The results indicate that very little differentiates those who attack high-value targets from those who attack members of the public. We conclude with a series of illustrations to theorize why this may be the case. Copyright © 2016 John Wiley & Sons, Ltd.

    The article on sex education in Portugal covers background, the educational system, the clashes of the 1960's over sex education, the Committee for the Study of Sexuality and Education (CSSE), the policies, politics and social movements during the period 1974 - 1984, the discussions in Parliament, the 1988 Reform of the Educational System, the Family Planning Association (FPA) and sex education, and the future role of the FPA. It was not until the institution of the multiparity parliamentary system in 1974 that discussing social and political changes was possible, culminating in 1984 with new legislation on abortion, family planning, and sex education. School reform came in 1987/8 with the Ministry of Education primarily responsible for curricula. The 1960's brought with it the influence of the Catholic Church. Change came in the form of progressivism among Catholics who replaced dogma with dialogue and listening. Sex education was considered as preparation for marriage, but masturbation, contraception, and prostitution were also discussed. In addition, the founder of FPA chaired the CSSE in 1971 and opened up debate on sex issues and drafted a bill to establish co-education in Portuguese schools. The revolution of 1974 brought an end to censorship and brought forth a policy of developing family planning. Changed in the Family Code gave women greater equality. UNFPA supported teacher training in non-sexist education. With human reproduction included in the natural sciences, there was still no school sex education policy and contraception was only sometimes represented in the biology curriculum. The focus of FPA was on contraception and abortion. Finally in the 1980's, the first sex education programs were developed for out-of-school youth. Even though in the 1970's there were leftists groups promoting sex education, it took leftist parliamentary power to get legislation on sex education in the schools adopted. The Ministry of Education however was pressured by the

    It is of global interest, for the definition of effective adaptation strategies, to make an assessment of climate change impacts in coastal environments. In this study, the salinity patterns adjustments and the correspondent Venice System zonations adaptations are evaluated through numerical modelling for Ria de Aveiro, a mesotidal shallow water lagoon located in the Portuguese coast, for the end of the 21st century in a climate change context. A reference (equivalent to present conditions) and three future scenarios are defined and simulated, both for wet and dry conditions. The future scenarios are designed with the following changes to the reference: scenario 1) projected mean sea level (MSL) rise; scenario 2) projected river flow discharges; and scenario 3) projections for both MSL and river flow discharges. The projections imposed are: a MSL rise of 0.42 m; a freshwater flow reduction of ∼22% for the wet season and a reduction of ∼87% for the dry season. Modelling results are analyzed for different tidal ranges. Results indicate: a) a salinity upstream intrusion and a generalized salinity increase for sea level rise scenario, with higher significance in middle-to-upper lagoon zones; b) a maximum salinity increase of ∼12 in scenario 3 and wet conditions for Espinheiro channel, the one with higher freshwater contribution; c) an upstream displacement of the saline fronts occurring in wet conditions for all future scenarios, with stronger expression for scenario 3, of ∼2 km in Espinheiro channel; and d) a landward progression of the saltier physical zones established in the Venice System scheme. The adaptation of the ecosystem to the upstream relocation of physical zones may be blocked by human settlements and other artificial barriers surrounding the estuarine environment.

    There is a lack of knowledge on the epidemiology of fungal infections worldwide because there are no reporting obligations. The aim of this study was to estimate the burden of fungal disease in Portugal as part of a global fungal burden project. Most published epidemiology papers reporting fungal infection rates from Portugal were identified. Where no data existed, specific populations at risk and fungal infection frequencies in those populations were used in order to estimate national incidence or prevalence, depending on the condition. An estimated 1,510,391 persons develop a skin or nail fungal infection each year. The second most common fungal infection in Portugal is recurrent vulvovaginal candidiasis, with an estimated 150,700 women (15-50 years of age) suffering from it every year. In human immunodeficiency virus (HIV)-infected people, oral or oesophageal candidiasis rates were estimated to be 19.5 and 16.8/100,000, respectively. Candidaemia affects 2.19/100,000 patients, in a total of 231 cases nationally. Invasive aspergillosis is less common than in other countries as chronic obstructive pulmonary disease (COPD) is uncommon in Portugal, a total of 240 cases annually. The estimated prevalence of chronic pulmonary aspergillosis after tuberculosis (TB) is 194 cases, whereas its prevalence for all underlying pulmonary conditions was 776 patients. Asthma is common (10% in adults) and we estimate 16,614 and 12,600 people with severe asthma with fungal sensitisation and allergic bronchopulmonary aspergillosis, respectively. Sixty-five patients develop Pneumocystis pneumonia in acquired immune deficiency syndrome (AIDS) and 13 develop cryptococcosis. Overall, we estimate a total number of 1,695,514 fungal infections starting each year in Portugal.

    After more than 40 years of democracy and 30 years of European integration, Portugal has bridged the research gap it had previously. However, when compared to global and European research policies, Portugal still has a long way go regarding investment in research and development. Health Research in Portugal has been managed by the Fundação para a Ciência e Tecnologia and the National Health Institute Doctor Ricardo Jorge, and it has not been a political priority, emphasized by the absence of a national scientific research plan for health, resulting in a weak coordination of actors in the field. The strategic guidelines of the 2004 - 2010 National Health Plan are what comes closest to a health research policy, but these were not implemented by the institutions responsible for scientific research for the health sector. Trusting that adopting a strategy of incentives to stimulate health research is an added-value for the Portuguese health system, the authors present five strategic proposals for research in health in Portugal.

    Immersive simulations can enable surgeons to learn complex sets of skills required for safe surgical practice without risk to patients. However, recruiting healthcare professionals to support surgeons training as members of an operating theatre (OT) team is challenging and resource intensive. We developed a training programme for actors to take on the role of an OT team to support validation studies in a simulated environment. This article describes the evaluation of the programme. The programme comprised of written materials, video discussion and experiential activities. Evaluation methods consisted of post-simulation interviews and questionnaires with actors and surgeons. Participants were recruited by convenience sampling. Quantitative data were analysed using descriptive statistics and interviews were analysed using thematic extraction. Three actors participated in the programme. Twelve surgeons completed simulations. All data suggest that the training was successful. Actors were perceived as realistic. Suggestions were made to improve training. After a brief training, actors can realistically portray members of an OT team in simulations designed to support surgeon training. This article highlights factors that contributed to success and suggests improvements. Although there are limitations with the study, its findings have relevance to training and assessment that focuses on individual clinician's functioning as a member of an OT team.

    2015-04-01

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

  6. Two simple models for accounting mussel contamination with diarrhoetic shellfish poisoning toxins at Aveiro lagoon: Control by rainfall and atmospheric forcing

    Vale, Paulo

    2012-02-01

    At Aveiro lagoon (Portuguese northwest coast) bivalve contamination with diarrhoetic shellfish poisoning toxins (DSTs), okadaic acid (OA) and dinophysistoxin-2 (DTX2), is a recurrent annual phenomenon seriously affecting seafood safety. The influence of meteorological parameters was studied to understand accumulation of DSTs in mussels, related to the blooming of the causative toxic microalgae, belonging to genus Dinophysis. Two simplified models were useful in predicting the accumulation of DSTs in blue mussels from this lagoon. Either the May river drainage or the rainfall accumulated from January through May could adequately predict the severity of OA accumulated from predation upon Dinophysis acuminata during June/July. In both cases a linear relationship was obtained, with correlation coefficients of 0.85 or greater. Winds with a west direction favour coastal concentration of Dinophysis acuta in Aveiro region. Both OA and DTX2 contamination increased exponentially in September/October with the cumulative number of days with W-wind orientation in the preceding August (correlation coefficients greater than 0.92). This relationship was attributed to the quadratic effect of wind stress on surface currents. August is a transitional month, when the continental runoff effect upon Dinophysis acuminata can still be observed and Dinophysis acuta advection may be promoted by westerly winds occurring in July. The frequency of periods with northerly winds in July can halt accumulation of toxins derived from Dinophysis acuta.

  7. Beyond the actor's traits: forming impressions of actors, targets, and relationships from social behaviors.

    Frey, K P; Smith, E R

    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.

    The aim of the present study was to investigate differences in the acoustic characteristics of the voice between adolescent actors and non-actors. The experimental sample consisted of 10 actresses and 10 actors while the control sample included 13 girls and 14 boys. Phonation of the vowel /a/, spontaneous speaking and oral reading provided a set of acoustic variables (fundamental frequency, jitter, shimmer, speaking and reading ranges); t test showed statistically significant differences between actresses and non-actresses in speaking range, reading F(0) maximum, and reading range, whereas between actors and non-actors the difference was found in reading range only. The results showed that drama in education without systematic voice training had no effects in terms of acoustic characteristics of the voice. Copyright 2002 S. Karger AG, Basel

    Objective: To evaluate an early home-supported discharge service for stroke patients. Design: We carried out a prospective, randomised, open-label, blinded-endpoint trial (allocation ratio of 1:1) with patients assigned to either an early home-supported discharge service or usual care. Setting: The study was undertaken in Aveiro, Portugal, between April 2009 and April 2013. Subjects: We included stroke patients aged 25–85 years admitted to the stroke unit with an initial Functional Independence Measure of up to 100, who gave informed consent. Interventions: Patients in the early home-supported discharge group began their rehabilitation intervention in the stroke unit and the early home-supported discharge team worked with them at home for a maximum of one month. Patients in the control group received usual services. Main measures: The primary outcome measure was the Functional Independence Measure at six months after stroke. Results: We randomised 190 patients of whom 34 were lost to follow-up. There were no significant differences (p > 0.5) in the average scores of Functional Independence Measure between the early home-supported discharge (69 ±22; mean ±SD) and the control groups (71 ±17) measured at baseline; and between the early home-supported discharge (107 ±20) and the control groups (107 ±25) measured at six months. The number of individuals with a low Functional Independence Measure score (<60) in the early home-supported discharge group compared with the control group was higher at admission (34/95 vs. 26/95) and lower at follow-up (2/74 vs. 5/78). Conclusions: It was feasible to implement early home-supported discharge procedures in a Southern European setting, but we have not shown convincing differences in disability at six months.

  18. Geology and religion in Portugal

    PubMed Central

    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.

  19. Structural fire risk of Portugal

    2017-04-01

    Portugal is on the top of the European countries most affected by vegetation fires which underlines the importance of the existence of an updated and coherent fire risk map. This map represent a valuable supporting tool for forest and fire management decisions, focus prevention activities, improve the efficiency of fire detection systems, manage resources and actions of fire fighting with greater effectiveness. Therefore this study proposed a structural fire risk map of the vegetated area of Portugal using a deterministic approach based on the concept of fire risk currently accepted by the scientific community which consists in the combination of the fire hazard and the potential economic damage. The existing fire susceptibility map for Portugal based on the slope, land cover and fire probability, was adopted and updated by the use of a higher resolution digital terrain model, longer burnt area perimeter dataset (1975 - 2013) and the entire set of Corine land cover inventories. Five susceptibility classes were mapped to be in accordance with the Portuguese law and the results confirms the good performance of this model not only in terms of the favourability scores but also in the predictive values. Considering three different scenarios of (maximum, mean, and minimum annual) burnt area, fire hazard were estimate. The vulnerability scores and monetary values of species defined in the literature and by law were used to calculate the potential economic damage. The result was a fire risk map that identifies the areas more prone to be affected by fires in the future and provides an estimate of the economic damage of the fire which will be a valuable tool for forest and fire managers and to minimize the economic and environmental consequences of vegetation fires in Portugal.

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

    The outreach programme Semanas da Astronomia (Astronomy Weeks) is held in late spring or summer on the island of Madeira, Portugal. This programme has been attracting enough interest to be mentioned in the regional press/TV/radio every year and is now, without doubt, the astronomical highlight of the year on Madeira. We believe that this programme is a good case study for showing how to attract the general public to astronomy in a small (population 250 000, area 900 km2) and fairly isolated place such as Madeira. Our Astronomy Weeks have been different each year and have so far included exhibitions, courses, talks, a forum, documentaries, observing sessions (some with blackouts), music and an astro party. These efforts may contribute towards putting Madeira on the map with respect to observational astronomy, and have also contributed to the planned installation of two observatories in the island.

    2011-05-01

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

  7. Vulnerability assessments as a political creation: tsunami management in Portugal.

    2017-10-01

    Vulnerability assessments are a cornerstone of contemporary disaster research. This paper shows how research procedures and the presentation of results of vulnerability assessments are politically filtered. Using data from a study of tsunami risk assessment in Portugal, the paper demonstrates that approaches, measurement instruments, and research procedures for evaluating vulnerability are influenced by institutional preferences, lines of communication, or lack thereof, between stakeholder groups, and available technical expertise. The institutional setting and the pattern of stakeholder interactions form a filter, resulting in a particular conceptualisation of vulnerability, affecting its operationalisation via existing methods and technologies and its institutional embedding. The Portuguese case reveals a conceptualisation that is aligned with perceptions prevalent in national government bureaucracies and the exclusion of local stakeholders owing to selected methodologies and assessment procedures. The decisions taken by actors involved in these areas affect how vulnerability is assessed, and ultimately which vulnerability reduction policies will be recommended in the appraisal. © 2017 The Author(s).

    2001-04-01

    The use of virtual reality (VR) presentations are becoming a more and more frequent means of communicating information and displaying data to large groups of viewers. VR presentations put heavy demands on reproduction of visual, aural, and tactile information. A common situation in VR presentations is that one actor acts in the virtual environment (VE), while a group of people observes the actors actions in the VE, often from the perspective of the actor. The current paper aims to study actors' (participants actively interacting with the VE) and observers' (participants passively observing the actors' interaction with the VE) evaluations of the VR presentation. In an experiment, 16 actors and 16 observers either acted in or observed a VE and performed ratings of the quality of the presentation. The results showed that actors experienced higher presence and realism, and enjoyed the VR experience more than observers did. Observers, on the other hand, experienced that external events distracted their attention more than actors did. Finally, actors experienced more symptoms of simulation sickness. However, no differences between actors and observers were found for ratings of audio quality.

    This field survey was designed to assess the environmental metal contamination status of Ria de Aveiro (Portugal). To achieve that goal, the concentrations of Cd, Hg, Cu and Zn in the sediments and water were assessed and Liza aurata hepatic metallothionein (MT) determined. The relationships between MT and environmental metal concentrations and hydrological factors were examined. Results revealed a wide distribution of metals both in water and sediments throughout the lagoon, mainly at Rio Novo do Principe (RIO) and Laranjo (LAR), at concentrations that may affect biota. MT concentrations were higher at the sites with high metal content (RIO and LAR). A significant positive correlation was found between MT and Cd in the sediments as well as with MT and Hg and Cu in the water. Moreover, a negative correlation between MT and salinity was found. Thus, the current data support MT use as a biomarker of metal exposure emphasizing the importance of hydrological parameters in its concentrations. Results suggest the continued monitoring of this lagoon system.

    To assess the educational value of improvisational actors in difficult conversation simulations to teach communication and relational skills to interprofessional learners. Surveys of 192 interprofessional health care professionals, and 33 teaching faculty, and semi-structured interviews of 10 actors. Descriptive statistics, Fisher's exact test and chi-square test were used for quantitative analyses, and the Crabtree and Miller approach was used for qualitative analyses. 191/192 (99.5%) interprofessional learners (L), and 31/33 (94%) teaching faculty (F) responded to surveys. All 10/10 actors completed interviews. Nearly all participants found the actors realistic (98%L, 96%F), and valuable to the learning (97%L, 100%F). Most felt that role-play with another clinician would not have been as valuable as learning with actors (80%L, 97%F). There were no statistically significant differences in perceived value between learners who participated in the simulations (47%) versus those who observed (53%), or between doctors, nurses, or psychosocial professionals. Qualitative assessment yielded five actor value themes: Realism, Actor Feedback, Layperson Perspective, Depth of Emotion, and Role of Improvisation in Education. Actors independently identified similar themes as goals of their work. The value attributed to actors was nearly universal among interprofessional learners and faculty, and independent of enactment participation versus observation. Authenticity, feedback from actors, patient/family perspectives, emotion, and improvisation were key educational elements. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Salmonella 1,4,[5],12:i:- is presently considered one of the major serovars responsible for human salmonellosis worldwide. Due to its recent emergence, studies assessing the demographic characterization and spatial epidemiology of salmonellosis 1,4,[5],12:i:- at local- or country-level are lacking. In this study, a analysis was conducted over a 10year period, from 2000 to the first quarter of 2011 at the Portuguese National Laboratory in Portugal mainland, with a total of 215 Salmonella 1,4,[5],12:i:- serotyped isolates obtained from human infections by a passive surveillance system. Data regarding source, year and month of sampling, gender, age, district and municipality of the patients were registered. Descriptive statistical analysis and a spatial scan statistic combined with a geographic information system were employed to characterize the epidemiology and identify spatial clusters. Results showed that most districts have reports of Salmonella 1,4,[5],12:i:-, with a higher number of cases at the Portuguese coastland, including districts like Porto (n=60, 27.9%), Lisboa (n=29, 13.5%) and Aveiro (n=28, 13.0%). An increased incidence was observed in the period from 2004 to 2011 and most infections occurred during May and October. Spatial analysis revealed 4 clusters of higher than expected infection rates. Three were located in the north of Portugal, including two at the coastland (Cluster 1 [RR=3.58, p≤0.001] and 4 [RR=10.42 p≤0.230]), and one at the countryside (Cluster 3 [RR=17.76, p≤0.001]). A larger cluster was detected involving the center and south of Portugal (Cluster 2 [RR=4.85, p≤0.001]). The present study was elaborated with data provided by a passive surveillance system, which may originate an underestimation of disease burden. However, this is the first report describing the incidence and the distribution of areas with higher risk of infection in Portugal, revealing that Salmonella 1,4,[5],12:i:- displayed a significant geographic clustering

    Since 1974 Portugal has experienced some dramatic changes in educational practices at the local level. The school has been opened to the community and the community to the school. Teacher education now includes community studies, designed to prepare teachers for an active role in this process and for the better understanding of the social background of pupils. One new practice is the publication of local newspapers or news-sheets to enhance the understanding of the community by teachers and pupils. The development of a school garden for the cultivation of flowers and vegetables serves as another bridge between school and community. Other examples of community action are adult literacy classes, the creation of voluntary organisations for women, the running of youth clubs, the formation of co-operatives, and local projects like the purchase of an old tram-car to be converted into a library. The introduction of `Civic and Polytechnic Education' for 13-16 year olds was an important innovation. One half-day a week was to be devoted to the integration of the school with the locality, young people's participation in society as agents of change, the linking of study and productive work, and the involvement of young people in the solution of national problems, working from a concrete knowledge of local and regional life. However, since 1976 there has been a more conservative approach, and only in places with a strong consensus amongst teachers has the new relationship between school and community been maintained.

    We describe our more than 10 years' experience working with actors and provide a "how-to" guide to recruiting, auditioning, hiring, training, and mentoring actors for work as simulated patients in simulation programs. We contend that trained actors add great realism, richness, and depth to simulation-based training programs. The actors experience satisfaction from their contributions, and their skill and improvisational talent allow programs to offer ethical and relational training, customized to a wide range of practitioners and adapted across a variety of health care conversations. Such learning opportunities can directly address Accreditation Council for Graduate Medical Education core competencies in preparing capable, confident, and empathic health care practitioners.

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

    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).

    The epidemiology of hepatitis B in Portugal is insufficiently characterized. We aimed to review the epidemiology of hepatitis B in Portugal since 1980. A literature review was performed in MEDLINE, Scielo, Web of Science, and the Portuguese Scientific Repository for studies containing 'Hepatitis B' and 'Portugal' published from 1980 to June 2016. The initial search was complemented by abstract books from national gastroenterology and hepatology meetings and reports from the Service for Intervention on Addictive Behaviours and Dependences, the Portuguese Blood Institute, and Directorate-General of Health. Further studies were identified in references of retrieved papers and https://www.google.pt. Ninety references were included. Hepatitis B surface antigen (HBsAg) prevalence was up to 2% in the general population and decreased in the last decades: 1.13-2.0% in studies carried out in 1980-1989 and 0.02-1.45% in studies carried out in 1990-2014. Among pregnant women, HBsAg prevalence was 1.35% in those on primary care, but 6.2% among risk parturients. Among drug abusers, HBsAg prevalence decreased from 10-19.6% in the decades of 1980-1990 to 4.8% in 2014. Higher HBsAg prevalence rates were observed among populations of African or Asian origin. Individuals with hepatitis B were mostly men, mean age 36.9-49 years. The most frequent viral genotype was D. Genotype E is more prevalent in patient cohorts from Central-Southern Portugal (10-62%) than those from Northern Portugal (1-4.1%). The proportion of inactive carriers varied from 24.2 to 73%. The prevalence of cirrhosis varied from 5.8 to 23.7%. Portugal is a low-endemicity country for hepatitis B. Nevertheless, prevalence is high among specific subgroups that may benefit from specifically designed healthcare programs.

    Objective To describe the experience of planning and developing online refresher courses in nursing management for nurses in the contexts of Brazil and Portugal. Method The instructional design was based on meaningful learning theory, andragogy, and dialectical methodology, so it valued interaction between the actors, emphasizing the scenarios of practice and applying the concepts covered. The course structure is divided into nine theoretical units, four case studies, and an essay exam. Results The course was positively evaluated by the participants, who reported opportunities for acquisition of new knowledge, interaction and exchange of experiences, motivation to study the topics, and self-learning. Conclusion It is expected that description of this experience will stimulate proposals for new courses and programs in distance education modalities, improving the processes of teaching and learning so as to give support to future analyses of their impact on the development and enhancement of management skills in nursing.

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

    PubMed

    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.

  8. A false dichotomy? Mental illness and lone-actor terrorism.

    PubMed

    Corner, Emily; Gill, Paul

    2015-02-01

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

    In this paper, we address the emergence of horticultural practice, agents, spaces and institutions in the two urban settings of Lisbon and Porto, in Portugal, during the second half of the nineteenth century. We do so by following the networking activities of two players: the self-made horticulturist and entrepreneur José Marques Loureiro, who created, in Porto, a commercial horticultural establishment and founded the Journal of Practical Horticulture; and the agronomist Francisco Simões Margiochi, head of the gardens and green grounds department of the municipality, who created the first course on gardening and horticulture, and founded the Royal Horticultural Society, both in Lisbon. Their joint activities were aimed at establishing horticulture as an applied science and to cater simultaneously to an extended audience of citizens. They enable us to enrich the narratives on the emergence and development of horticulture in Europe by calling attention to the participation in circulatory extended networks of actors who are often absent from these accounts. Additionally, they allow a comparative assessment of the outcome of their actions at the national level, and to understand their results in terms consonant with recent historiographical trends on the co-construction of centres and peripheries.

    From June 2004 to December 2007, samples were weekly collected at a fixed station located at the mouth of Ria de Aveiro (West Iberian Margin). We examined the seasonal and inter-annual fluctuations in composition and community structure of the phytoplankton in relation to the main environmental drivers and assessed the influence of the oceanographic regime, namely changes in frequency and intensity of upwelling events, over the dynamics of the phytoplankton assemblage. The samples were consistently handled and a final subset of 136 OTUs (taxa with relative abundance > 0.01%) was subsequently submitted to various multivariate analyses. The phytoplankton assemblage showed significant changes at all temporal scales but with an overriding importance of seasonality over longer- (inter-annual) or shorter-term fluctuations (upwelling-related). Sea-surface temperature, salinity and maximum upwelling index were retrieved as the main driver of seasonal change. Seasonal signal was most evident in the fluctuations of chlorophyll a concentration and in the high turnover from the winter to spring phytoplankton assemblage. The seasonal cycle of production and succession was disturbed by upwelling events known to disrupt thermal stratification and induce changes in the phytoplankton assemblage. Our results indicate that both the frequency and intensity of physical forcing were important drivers of such variability, but the outcome in terms of species composition was highly dependent on the available local pool of species and the timing of those events in relation to the seasonal cycle. We conclude that duration, frequency and intensity of upwelling events, which vary seasonally and inter-annually, are paramount for maintaining long-term phytoplankton diversity likely by allowing unstable coexistence and incorporating species turnover at different scales. Our results contribute to the understanding of the complex mechanisms of coastal phytoplankton dynamics in relation to changing

  12. Towards a computational model of actor-based language comprehension.

    Neurophysiological data from a range of typologically diverse languages provide evidence for a cross-linguistically valid, actor-based strategy of understanding sentence-level meaning. This strategy seeks to identify the participant primarily responsible for the state of affairs (the actor) as quickly and unambiguously as possible, thus resulting in competition for the actor role when there are multiple candidates. Due to its applicability across languages with vastly different characteristics, we have proposed that the actor strategy may derive from more basic cognitive or neurobiological organizational principles, though it is also shaped by distributional properties of the linguistic input (e.g. the morphosyntactic coding strategies for actors in a given language). Here, we describe an initial computational model of the actor strategy and how it interacts with language-specific properties. Specifically, we contrast two distance metrics derived from the output of the computational model (one weighted and one unweighted) as potential measures of the degree of competition for actorhood by testing how well they predict modulations of electrophysiological activity engendered by language processing. To this end, we present an EEG study on word order processing in German and use linear mixed-effects models to assess the effect of the various distance metrics. Our results show that a weighted metric, which takes into account the weighting of an actor-identifying feature in the language under consideration outperforms an unweighted distance measure. We conclude that actor competition effects cannot be reduced to feature overlap between multiple sentence participants and thereby to the notion of similarity-based interference, which is prominent in current memory-based models of language processing. Finally, we argue that, in addition to illuminating the underlying neurocognitive mechanisms of actor competition, the present model can form the basis for a more comprehensive

    PubMed

    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.

    The objective of this study was to compare the mortality of Polish actors (males and females) with the general Polish population for the period 1981-1999 and for two sub-periods: 1981-1991 and 1992-1998. Initially the studied cohort included 3992 dramatic actors (2161 males, 1831 females) of age 18-80 years (at the moment of cohort entrance). After detailed data verification statistical analysis was made for 2120 actors and 1767 actresses, contributing 29477.1 and 24886.2 person-years of observation, respectively. A total of 633 deaths (368 males and 265 females) were noted during the analyzed period. Statistical approach based on the follow-up method. Comparison with the reference population (Polish males and females from urban areas) was made by means of the standardized mortality ratios (SMRs) and their 95% confidence intervals. Direct comparison of the selected subgroups' mortality based on the rate ratio analysis. Standardized mortality ratios were 0.739 (95%CI: 0.666-0.819) for the actors and 0.887 (95%CI: 0.784-1.001) for actresses. Mortality of the actors' cohort was found to be significantly lower than in the reference population during total analyzed period, whereas for actresses no significant differences were found. Age-specific SMR dependence was found. Statistically significant lowering of SMR was observed for actors up to 80 years old. Finally, it could be concluded that in contrast to the actresses' cohort the actors' mortality in 1992-1999 significantly decreased in relation to 1981-1991 period. Moreover, the decrease of the actors' mortality exceeded tendencies observed for Polish urban population.

Six samples of LO define a whole rock isochron age of 285±15 Ma with (87Sr/86Sr)i = 0.7051±0.001 (MSWD = 0.11). Two monazite analyses for the LO granite yield an weighted average 207Pb/235U age of 297.19±0.73 Ma, consistent with the preliminary ID-TIMS U-Pb analyses of two transparent and euhedral prisms of zircon that define a concordia age of 296.37 ±0.52 Ma (MSWD = 0.66). The linear trends of major and trace elements variation diagrams of LO and AC granites and their similar mean values of (87Sr/86Sr)i point, at this stage, to an involvement of mid-crustal sources, probably mixed with asthenospheric material. Therefore, LOP consists of post-D3 biotite granites installed in higher structural crustal levels, testifying the occurrence of a crustal growth episode after the major recycling processes that occurred during the deformation phase D3.

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.

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

    The mobility of health professionals in the European Union is a phenomenon which policy-makers must take into account to provide the conditions to adjust for demand and supply of health services. This paper presents the case of Portugal, a country which at the same time imports and exports health workers. Since the early 1990s Portugal became a destination country receiving foreign health care professionals. This situation is now changing with the current economic situation as fewer immigrants come and more Portuguese emigrate. Foreigners coming to Portugal do so in part for similar reasons that bring Portuguese to want to emigrate, mainly the search for better work conditions and professional development opportunities. The emigration of Portuguese health professionals is also stimulated by the difficulty for recently graduated nurses, dentists and diagnostic and therapeutic technicians to find employment, low salaries in the public and private sectors, heavy workloads, remuneration not related to performance and poor career prospects. The paradoxes described in this study illustrate the consequences of the absence of a policy for the health professions. Strategies based on evidence, and on an integrated information system that captures the dynamic evolution of the workforce in health are not only necessary but also a good investment.

    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. Copyright © 2016 Elsevier B.V.

    2010-04-15

    When another person takes 10 pounds from your hand, it matters if they are a shopkeeper or a robber. That is, the meaning of a simple, goal-directed action can vary depending on the identity of the actors involved. Research examining action understanding has identified an action observation network (AON) that encodes action features such as goals and kinematics. However, it is not yet known how or where the brain links actor identity to action goal. In the present paper, we used a repetition suppression paradigm during functional magnetic resonance imaging (fMRI) to examine the neural representation of actor identity within the context of object-directed actions. Participants watched video clips of two different actors with two different object-goals. Repeated presentation of the same actor suppressed the blood oxygen level-dependent (BOLD) response in fusiform gyrus and occipitotemporal cortex. In contrast, repeated presentation of an action with the same object-goal suppressed the BOLD response throughout the AON. Our data reveal an extended brain network for understanding other people and their everyday actions that go beyond the traditional action observation network.

  9. Body height and occupational success for actors and actresses.

    2010-08-01

    The association of body height with occupational success has been frequently studied, with previous research mainly finding a positive effect among men and positive or null effects among women. Occupational success has almost exclusively been measured so far by short-term success variables (e.g., annual income). In the present study, the relationship of success and height was examined in a group of actors and actresses using a large online database about movies (Internet Movie Database) where heights of actors and actresses are stated. The number of roles played in movies and television series during each actor's lifetime was used as a measure of long-term occupational success. No height effect was found for male actors but a significant negative effect was found for actresses, even after controlling for possible confounding influences (age and birth year). Compared to the general population, actors and actresses were significantly taller; however, actresses who were shorter than average were more likely to achieve greater occupational success, in terms of being featured in more movies.

    Qubbaj, Murad R.; Muneepeerakul, Rachata

    2012-11-01

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

    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.

    2013-01-01

    This paper focuses on the policy context for the deployment of nurses in advanced roles, with particular reference to Portugal. The health sector in Portugal, as in all countries, is labour intensive, and the scope to utilise nurses in more advanced roles is currently being debated. Mixed methods were used: an analysis of international data on the nursing workforce; an analysis of documents and media articles; interviews with key-informants; an online survey of managers, and a technical workshop with key-informants. The limited evidence base on nurses in advanced roles in Portugal is a constraint on progress, but it is not an excuse for inaction. Further research in Portugal on health professionals in innovative roles would assist in informing policy direction. There is the need to move forward with a fully informed policy dialogue, taking account of the current political, economic and health service realities of Portugal.

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

  20. Portugal takes step back on abortion legalization.

    PubMed

    1998-07-01

    According to international press reports, a law that would have allowed Portuguese women abortions through the 10th week of pregnancy and into the 16th week if their physical or mental health was at risk has been rescinded after a referendum to determine the statute's future was voided because of low voter turnout. Passed in February, the law was a liberalization of Portugal's strict anti-abortion laws, which ban all abortions except for narrowly defined medical reasons or in the case of rape (and those are permitted only until the 12th week of pregnancy). Because the issue is such a controversial one, politicians had turned to a national referendum asking Portuguese voters to overturn or ratify the new law. The referendum was the first in the country since the end of its right-wing dictatorship in 1974, and 50% participation was required. Only 31.5% of the country's 8.5 million eligible voters went to the polls on June 28. Of those voting, 50.9% voted against the liberalized new legislation. Sunny weather and World Cup soccer matches were both pointed to as reasons for the low turnout. Officials estimate there are some 20,000 illegal abortions annually in Portugal. Abortion-rights activists in the mostly Roman-Catholic country say hospitals see roughly 10,000 women a year suffering from complications from illegal abortions, and that at least 800 women die each year from the procedure. In the next day's Diario de Noticias, a daily paper in Portugal, the entire front page was filled with a giant question mark. "What now, lawmakers?" the headline read. full text

    Nuclear medicine in Portugal has been an autonomous speciality since 1984. In order to obtain the title of Nuclear Medicine Specialist, 5 years of training are necessary. The curriculum is very similar to the one approved under the auspices of the European Union of Medical Specialists, namely concerning the minimum recommended number of diagnostic and therapeutic procedures. There is a final assessment, and during the training the resident is in an approved continuing education programme. Departments are accredited by the Medical College in order to verify their capacity to host nuclear medicine residencies.

    Whenever several therapeutic options exist, multidisciplinary decision-making is beneficial for the patient and for society at large. The main obstacles to the establishment of heart teams in Portugal are organizational and logistical. Implementing a heart team approach entails definition of the situations requiring multidisciplinary discussion, creation of clear lines of communication, written protocols and obtaining patient informed consent. The European Society of Cardiology guidelines define the clinical scenarios where intervention of the heart team is recommended. Copyright © 2013 Sociedade Portuguesa de Cardiologia.

    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.

    EPA Pesticide Factsheets

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

    The selection of spatial and temporal scales of analysis is an important and challenging activity at the start of any Policy Analysis or Strategic Environmental Assessment (SEA). The scale sets bounds on the types of problems to be addressed, the solutions to be found and the impacts to be evaluated. Particular scale choices may be more or less beneficial to different actors and are therefore politically loaded. Despite its importance, this topic has rarely been specifically addressed through empirical research. This paper presents an assessment of the impacts of scale choice from varying points of view - those of political actors, commissioners, analysts and scientists - focusing on one type of scale choice: the spatial boundary of the study. An examination of the completed transboundary Long Term Vision Study (LTV) of the Scheldt Estuary, commissioned by the Flemish and Dutch governments, is used to illustrate how actors vary both in the boundaries they choose and the assessment they make of the implications of that boundary choice. Consequently, no perfect spatial scale choice appears to exist. The paper recommends ways to structure the problem of scale selection to facilitate rational deliberation. It is suggested that the methods used to analyse different actors perspectives for the completed LVT study, in future could be employed up-front at the start of other projects. Scale-dependent decision trade-offs could then be made more transparent.

    On the 21st of June 2002, in Copenhagen, the Regional Commission for the Certification of Poliomyelitis Eradication, declared the European Region of the World Health Organization (WHO) as polio-free. The last case (not imported) of poliomyelitis in Europe had occurred in November 1998. The health impact is enormous. In Portugal, the last case of poliomyelitis caused by the wild poliovirus, had occurred in December 1986. The path to eradication in Portugal had begun with a vaccination campaign in 1965/1966, with the oral polio vaccine (Sabin). High vaccination coverage has been maintained since then. The Portuguese program to eliminate poliomyelitis follows the strategic recommendations of WHO, with three components: vaccination; surveillance of acute placid paralysis (AFP); laboratory containment of wild polioviruses. Global eradication has not yet been achieved but is likely to happen till 2005. Keeping the high levels of motivation among Portuguese health workers is essential, in order not to loose what has been achieved. High vaccination coverage has to be maintained. Surveillance of AFP has to be improved and the prompt notification of cases by hospital clinicians, sending stool samples to the reference laboratory, is essential for the success of this activity. The laboratory containment programme is important to prevent the accidental reintroduction of poliomyelitis from laboratories.

    2016-01-01

    This article presents the emergence and development of modern sexology in Portugal through the analysis of Portuguese sexologists' narratives, to explore how they commit to a professional identity as sexologists, and to discuss how they integrate their professional role into the vast multidisciplinary field of sexology. In-depth interviews were conducted with 44 key professionals, purposefully recruited to guarantee heterogeneity concerning generation, gender, training, and practice. Content analysis focused on highlighting differences and articulations among the main professionals making up the field. The findings indicate that sexology is not seen as a full-fledged profession but rather as a specialization or a secondary field of action. The sexual medicine perspective is prevalent and more visible among physicians, thus reflecting the gap between psychosocial and biomedical approaches. A close link between clinical work and research and a gap between clinical work and health promotion were found. Despite the multidisciplinary nature of sexology being acknowledged, it is not fully implemented by the experts in the field. However, it is this characteristic that permitted sexology to institutionalize and to legitimate itself as a discourse of truth about sex, in Portugal as in other countries.

    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 < 0.001). Women who reported being victims of violence during the previous year stated that the episodes occurred more often at home (54.4 %) with the partner as the perpetrator (43.9 %). On the other hand, male victims stated that the violent episodes occurred mostly in public spaces (40.8 %); men indicated that the perpetrator was frequently a stranger (28.6 %) or a co-worker (18.4 %). Violence is a frequent problem among both female and male immigrants living in Portugal, with different gender patterns regarding the perpetrators and settings of abuse.

    Coccidiosis caused by Eimeria species is a major form of intestinal infection affecting intensively and semi-intensively reared goats. The province of Alentejo is the main goat-producing area in Portugal. Therefore, all 15 Serpentina goat farms in Alentejo were analyzed regarding the occurrence and diversity of Eimeria species. Fecal samples obtained from 144 animals (52.1% dairy goats, 47.9% pre-pubertal goats) were examined using the modified McMaster technique to determine the number of oocysts per gram of feces. Eimeria spp. oocysts were present in 98.61% of the fecal samples and, overall, nine different Eimeria species were identified. The most prevalent species were E. ninakohlyakimovae (88%) and E. arloingi (85%), followed by E. alijevi (63%) and E. caprovina (63%). The average number of oocysts shed was significantly lower in dairy goats than in pre-adult animals. Astonishingly, no clinical signs of coccidiosis were observed in any of the animals examined, even though they were shedding high numbers of oocysts and were infected with highly pathogenic species. Thus, implementation of routine diagnostic investigation of the occurrence and diversity of caprine Eimeria species may be a useful tool for determination and better understanding of their potential economic impact on goat herds in southern Portugal.

  19. Post-fire vegetation dynamics in Portugal

    2009-04-01

    The number of fires and the extent of the burned surface in Mediterranean Europe have increased significantly during the last three decades. This may be due either to modifications in land-use (e.g. land abandonment and fuel accumulation) or to climatic changes (e.g. reduction of fuel humidity), both factors leading to an increase of fire risk and fire spread. As in the Mediterranean ecosystems, fires in Portugal have an intricate effect on vegetation regeneration due to the complexity of landscape structures as well as to the different responses of vegetation to the variety of fire regimes. A thorough evaluation of vegetation recovery after fire events becomes therefore crucial in land management. In the above mentioned context remote sensing plays an important role because of its ability to monitor and characterise post-fire vegetation dynamics. A number of fire recovery studies, based on remote sensing, have been conducted in regions characterised by Mediterranean climates and the use of NDVI to monitor plant regeneration after fire events was successfully tested (Díaz-Delgado et al., 1998). In particular, several studies have shown that rapid regeneration occurs within the first 2 years after the fire occurrences, with distinct recovery rates according to the geographical facing of the slopes (Pausas and Vallejo, 1999). In 2003 Portugal was hit by the most devastating sequence of large fires, responsible by a total burnt area of 450 000 ha (including 280 000 ha of forest), representing about 5% of the Portuguese mainland (Trigo et al., 2006). The aim of the present work is to assess and monitor the vegetation behaviour over Portugal following the 2003 fire episodes. For this purpose we have used the regional fields of the Normalized Difference Vegetation Index (NDVI) as obtained from the VEGETATION-SPOT5 instrument, from 1999 to 2008. We developed a methodology to identify large burnt scars in Portugal for the 2003 fire season. The vegetation dynamics was then

    Previous research has shown that the media can play a role in shaping consumer perceptions during a public health crisis. In order for public health professionals to communicate well-informed health information to the media, it is important that they understand how media view their role in transmitting public health information to consumers and decide what information to present. This paper reports the perceptions of media actors from three countries about their role in reporting information during a food incident. This information is used to present ideas and suggestions for public health professionals working with media during food incidents. Thirty three semi-structured interviews with media actors from Australia, New Zealand and the United Kingdom were conducted and analysed thematically. Media actors were recruited via purposive sampling using a sampling strategy, from a variety of formats including newspaper, television, radio and online. Media actors said that during a food incident, they play two roles. First, they play a role in communicating information to consumers by acting as a conduit for information between the public and the relevant authorities. Second, they play a role as investigators by acting as a public watchdog. Media actors are an important source of consumer information during food incidents. Public health professionals can work with media by actively approaching them with information about food incidents; promoting to media that as public health professionals, they are best placed to provide the facts about food incidents; and by providing angles for further investigation and directing media to relevant and correct information to inform such investigations. Public health professionals who adapt how they work with media are more likely to influence media to portray messages that fit what they would like the public to know and that are in line with public health recommendations and enable consumers to engage in safe and health promoting

  1. VR/IS Lab Virtual Actor research overview

    1995-06-22

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

  2. Balancing influence between actors in healthcare decision making

    PubMed Central

    2011-01-01

    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 improved transparency of

    2001-01-01

    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.

  4. Structural fire risk: The case of Portugal.

    Parente, Joana; Pereira, Mário G

    2016-12-15

    This study is focused in mapping the structural fire risk in the vegetated area of Portugal using a deterministic approach based on the concept of fire risk currently accepted by the scientific community which consists in the combination of the fire hazard and the potential economic damage. The fire susceptibility map of Verde and Zêzere (2010) was adopted and updated by the use of a higher resolution digital terrain model, longer burnt area perimeter dataset (1975-2013) and the entire set of Corine land cover inventories. The susceptibility was mapped with five classes to be in accordance with the Portuguese law and the results confirms the good performance of this model not only in the favourability scores but also in the predictive values. Three different scenarios of (maximum, mean, and minimum annual) burnt area were consider to estimate the fire hazard which allow to estimate the likelihood of a pixel to burn (ranging between 0% and 20%) depending on the class to which it belongs and on the future burnt area scenario. The potential economic damage was estimated with the vulnerability scores and monetary values of species defined in the literature and by law. The obtained fire risk map identifies the areas more prone to be affected by fires in the future and provides an estimate of the economic damage of the fire which will be a valuable tool for forest and fire managers and to minimize the economic and environmental consequences of vegetation fires in Portugal.

    The use of guidelines for neonatal parenteral nutrition (PN) improves its clinical efficiency and the safety of prescription. To evaluate the practices of neonatal parenteral nutrition prescription in Portugal, and the adherence to the National Consensus on neonatal PN (2008). A questionnaire based on a multiple choice response on parenteral nutrition prescription was conducted, and sent to the coordinators of the 50 public and private Portuguese neonatal special care units, 25 being level III and 25 level II. Parenteral nutrition was prescribed in 32 neonatal units, 23 of which (71.9%) responded to the questionnaire. Of the respondents, 19 (82.6%) refer to follow the National Consensus, the remaining following local guidelines; 17 (73.9%) of units referred to using an electronic based system for prescription. In preterm neonates, most mentioned: administering judiciously the fluid intake during the first post-natal week; starting amino acids from the first post-natal day with 1.5-3g/kg/d, increasing up to 3-4g/kg/d; starting lipids from the first three post-natal days with 1g/kg/d, increasing up to 3g/kg/d; administering 40-70mg/kg/d of calcium and of phosphorus with the fixed calcium:phosphorus ratio of 1.7: 1 (mg:mg); and estimating the osmolality of the solutions, and weekly monitoring of serum triglycerides, blood urea, serum phosphorus and liver function. The high response rate is probably representative of the practice of PN prescription in Portugal. Most of the units used the National Consensus on neonatal PN as a reference, thus contributing to better nutritional support for neonates. Copyright © 2012 Asociación Española de Pediatría.

    Photovoltaic (PV) technology has been gaining a significant share in Portugal's renewable energy mix. In this paper we focus on the analysis of 29 PV systems (mounted and connected to the grid under the micro-generation incentive scheme in Portugal), from which 59% are DoubleSun® technology, the remaining being flat-plate systems. The period in analysis is July 2009-June 2010. A preliminary analysis of the PV systems has confirmed their high potential in Portugal and highlighted the relevance of such analysis to identify: (1) the geographical characterization of PV performance across mainland Portugal; (2) improvement of a tool [1] that predicts the potential of different PV technologies; and (3) the challenges of PV systems when installed on-field and connected to the grid.

    Collins, Harry; Evans, Robert

    2014-10-01

    We question the logic of Coopmans and Button's critique of our analysis of expertise on three grounds. First, their critique depends on a clear distinction between actor and analysts that we show cannot be maintained. Second, we question their reticence to allow the use of taxonomies in the analysis of expertise, suggesting that it is contradicted by their own descriptions of expert work, and we accuse them of making a mistake in the way they relate commonsense to specialist skills. Finally, we express our puzzlement at the antiseptic-like precautions that some ethnomethodologists apply to analysts' categories, especially given that--as we show--analysts' categories sometimes provide a superior resource for understanding and can change the actors' world as well as describing it.

  8. Performance Analysis of an Actor-Based Distributed Simulation

    NASA Technical Reports Server (NTRS)

    Schoeffler, James D.

    1998-01-01

    Object-oriented design of simulation programs appears to be very attractive because of the natural association of components in the simulated system with objects. There is great potential in distributing the simulation across several computers for the purpose of parallel computation and its consequent handling of larger problems in less elapsed time. One approach to such a design is to use "actors", that is, active objects with their own thread of control. Because these objects execute concurrently, communication is via messages. This is in contrast to an object-oriented design using passive objects where communication between objects is via method calls (direct calls when they are in the same address space and remote procedure calls when they are in different address spaces or different machines). This paper describes a performance analysis program for the evaluation of a design for distributed simulations based upon actors.

    In the spring of 2006, a rather unusual advertisement by the Centre of Teaching and Academic Growth at UBC (http://www.tag.ubc.ca) came to my attention. Faculty members were invited to take part in a workshop entitled "All the World's a Stage: Teachers as Actors," offered by a zoology instructor and an amateur actor, Greg Bole: Teaching can be seen as creating an interpersonal relationship and hence uses many of the same skills as acting. The investigation and use of acting skills in teacher preparation can allow a greater facility with diverse methods, increase skill at adapting to change in the classroom or lecture hall, and an increased ability to quickly form positive relationships with students.

    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

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

    PubMed

    McAdams, Dan P

    2013-05-01

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

    2015-06-01

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

    Abstract Relational maintenance is connected to high quality friendships. Friendship maintenance behaviors may occur online via social networking sites. This study utilized an Actor-Partner Interdependence Model to examine how Facebook maintenance and surveillance affect friendship quality. Bryant and Marmo's (2012) Facebook maintenance scale was evaluated, revealing two factors: sharing and caring. Facebook surveillance was also measured. For friendship satisfaction and liking, significant positive actor and partner effects emerged for caring; significant negative actor, partner, and interaction effects emerged for sharing; and significant positive actor effects emerged for surveillance. For friendship closeness, significant positive actor effects emerged for caring and surveillance.

    Prior research has indicated that positive moods increase but negative moods decrease the trait activation of spontaneous trait inferences (STIs). However, it is unknown whether this difference is also present in STIs about the actor. In Study 1, using a false recognition paradigm, we found that Chinese undergraduates made STIs about the actor. In Study 2, we found that the happy Chinese undergraduates were more likely to make STIs about the actor than the sad Chinese undergraduates. These findings showed that Chinese people made STIs about the actor and moods had an influence on their STIs about the actor.

    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.

    Portugal is located next to the plate boundary between Eurasia (Iberia) and Africa (Nubia). The country has been repeatedly affected by some of the largest earthquakes, both onshore and offshore, in the historical European record, including the largest historical European earthquake, the great Lisbon earthquake of 1755 (~M8.5). The Portuguese territory has suffered directly the consequences of strong ground shaking (collapse of buildings, etc) and also some of the most destructive consequences of earthquakes (e.g. tsunamis, fires, etc). However, the rate of tectonic deformation in the Portuguese territory is low (the Eurasian-African plates converge at a rate of ~ 5 mm/yr), which results in long recurrence intervals between earthquakes. This low to moderate rate of seismic activity has two major negative effects: 1) it is difficult to study the regional seismo-tectonics with traditional passive methods; 2) the population is little aware of earthquake risk and unprepared to react in case of disaster. In this scenario, real-time seismology is key to monitoring earthquake crisis in real-time, providing early warnings about potentially destructive events, and assisting in the channeling of recovery efforts in case of disaster. In this paper we will present the real-time algorithms implemented at Instituto de Meteorologia (IM), the institution responsible for seismic monitoring in Portugal. In particular, we will focus on the following aspects: 1) Data collection and real-time transmission to the headquarters. Broadband seismological stations are owned and operated by five different institutions. The last years have witnessed an effort for integration, and presently most data arrives at IM lab in real-time. 2) Earthquake location and local magnitude determination. Data is automatically analyzed in order to obtain a first earthquake hypocenter and ML. While this process is mostly automatic, it still requires the revision by an operator, who is available 24h. 3

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

    The Terrorist Radicalization Assessment Protocol (TRAP-18) is a structured professional judgment instrument for the assessment of individuals who present a concern for lone-actor terrorism. It consists of eight proximal warning behaviors and 10 distal characteristics. Previous research has demonstrated its interrater reliability and some concurrent and postdictive validity. In this article, TRAP-18 is retrospectively applied to the case of US Army psychiatrist and jihadist Malik Nidal Hasan, who committed a mass murder at Fort Hood, Texas in 2009. The strengths and limitations of TRAP-18 as a structured professional judgment instrument for mental health clinicians are discussed, and clinical risk management suggestions are made.

    Two components of lay observers' calculus of moral judgment are proximal intent (the actor's mind is focused on performing the action) and distal intent (the actor's mind is focused on the broader goal). What causes observers to prioritize one form of intent over the other? The authors observed whether construal level (Studies 1–2) and beliefs about free will (Studies 3–4) would influence participants' sensitivity to the actor's proximal vs. distal intent. In four studies, participants read scenarios in which the actor's proximal and distal intent were independently manipulated. In Study 1, when only distal intent was present in the actor's mind, participants rated the psychologically distant actor more responsible than the psychologically near actor. In Study 2, when only distal intent was in the actor's mind, participants with a chronic high level of action identification rated the actor more responsible than did those with a low level of action identification. In both studies, when only proximal intent was in the actor's mind, construal level did not predict judgments of responsibility. In Study 3, when only proximal intent was present in the actor's mind, the more participants believed in free will, the more they rated the actor responsible. When only distal intent was in the actor's mind, free will belief did not influence ratings of responsibility. In Study 4, the same pattern emerged when free will/determinism beliefs were manipulated and the actor performed a positive (life-saving) act. The authors discuss how these results shed new light on the literatures on moral reasoning and psycho-legal theory. PMID:26106352

    Anaphylaxis has a growing incidence, especially in children. It represents a medical emergency and its successful therapy depends on early and proper intervention. Intramuscular epinephrine, with dose adjustment according to weight and age, is the drug of choice for anaphylaxis treatment. After resolution of the acute reaction, the patient should be kept under clinical surveillance for 6 to 24 hours, due to possible biphasic reactions. Prescription of an epinephrine auto injectable device should be considered in all patients with diagnosed or suspected anaphylaxis; additionally these patients should always be referred to an Immunoallergy consultation, to perform adequate investigation and management in order to reduce future risk. All anaphylaxis episodes must be recorded in The Portuguese Catalogue of Allergies and other Adverse Reactions (Catálogo Português de Alergias e outras Reações Adversas, CPARA), which represents a fundamental tool to share clinical information within the Health System. The present manuscript intends to disclose the most recent Portuguese guidelines for the diagnosis and treatment of anaphylaxis, making its clinical approach more effective and homogeneous, and to promote the use of The Portuguese Catalogue of Allergies and other Adverse Reactions as an essential tool to register and share information on anaphylaxis in Portugal.

    The cortical correlates of speech and music perception are essentially overlapping, and the specific effects of different types of training on these networks remain unknown. We compared two groups of vocally trained professionals for music and speech, singers and actors, using recited and sung rhyme sequences from German art songs with semantic and/ or prosodic/melodic violations (i.e. violations of pitch) of the last word, in order to measure the evoked activation in a magnetoencephalographic (MEG) experiment. MEG data confirmed the existence of intertwined networks for the sung and spoken modality in an early time window after word violation. In essence for this early response, higher activity was measured after melodic/prosodic than semantic violations in predominantly right temporal areas. For singers as well as for actors, modality-specific effects were evident in predominantly left-temporal lateralized activity after semantic expectancy violations in the spoken modality, and right-dominant temporal activity in response to melodic violations in the sung modality. As an indication of a special group-dependent audiation process, higher neuronal activity for singers appeared in a late time window in right temporal and left parietal areas, both after the recited and the sung sequences.

    1996-06-01

    Discussions at the workshop centered around the Oxfam UK/1 program work on gender with its partners and other actors. Gender issues have been part of the program since 1985. Around 80% of the program involves mixed partners (men and women), while around 15% involves women-only groups. Strategies for working with partners include training, ongoing dialogue, involvement in planning, networking, lobbying, advocacy work, sectoral interventions, and research to highlight issues. Improving the gender work of existing counterparts and building new relationships are the goals of the Oxfam UK/1 program. Gender awareness should be used as a criterion in choosing those with whom work is done. Time-bound strategies are needed to persuade partners to respond to the gender-related needs of target groups. Resources are needed to enhance the capacity skills of willing partners. The workshop produced the following recommendations: 1) program managers must take conscious steps to invest time and resources in seeking out new relationships with new potential actors; 2) local culture should be analyzed to develop a locally appropriate approach to gender discrimination, and strategies have to synchronize policy directives with what is happening on the ground; 3) in seeking new relationships, centers of positive energy, which can create a domino effect and break down resistance, should be identified; and 4) networking should be broadened to outside the current universe of counterparts.

    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.

    [Purpose] The purpose of the study was to assess the health effects of broadcasting actors through a comprehensive research on their job stress, psychosocial stress, and fatigue and to investigate those factors having an impact on their health condition to present a basis for comparative studies and effective human resource management in the future. [Subjects and Methods] A survey was performed to analyze the relevance of the general features, job stress, psychosocial stress, and fatigue. [Results] Analysis of job stress, one of the characteristics of individuals, revealed that 32.4% of the subjects with less than 5 years of service, 55.5% of those with 6 to 10 years of service, and 52.4% of those with more than 10 years of service showed a high level of stress. Analysis of psychosocial stress, another characteristic of individuals, revealed that 13.4% of the nonsmokers had a high level of psychosocial stress, while 37.7% of smokers had a high level of psychosocial stress based on analysis of chronic disease and psychosocial health. [Conclusion] Based on this study of the stress and fatigue of broadcasting actors, it is expected that improvements can be made to promote their mental health conditions and, organizational safety and to promote effective human resource management.

    Spectrographic analysis of male actors' voices showed a cluster, the "actor's formant" (AF), which is related to the perception of good and projected voice quality. To date, similar phenomena have not been described in the voices of actresses. Therefore, the objective of the current investigation was to compare actresses' and nonactresses' voices through acoustic analysis to verify the existence of the "AF" cluster or the strategies used to produce the performing voice. Thirty actresses and 30 nonactresses volunteered as subjects in the present study. All subjects read a 40-second text at both habitual and loud levels. Praat (v.5.1) was then used to analyze equivalent sound pressure level (Leq), speaking fundamental frequency (SFF), and in the long-term average spectrum window, the difference between the amplitude level of the fundamental frequency and first formant (L1-L0), the spectral tilt (alpha ratio), and the amplitude and frequency of the "AF" region. Significant differences between the groups, in both levels, were observed for SFF and L1-L0, with actresses presenting lower values. There were no significant differences between groups for Leq or alpha ratio at either level. There was no evidence of an "AF" cluster in the actresses' voices. Voice projection for this group of actresses seemed to be mainly a result of a laryngeal setting instead of vocal tract resonances. Copyright © 2012 The Voice Foundation. Published by Mosby, Inc.

    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.

    The prevalence of heart failure is increasing all over the world. It is a common and growing public health problem in Portugal as in many other European countries. This article provides a review of health service organization and current heart failure management in Portugal, discusses primary care and ward practices in different hospitals and reports on the use of proven standard therapies for the treatment of heart failure in the community. Despite major advances in diagnosis and treatment, heart failure is only satisfactorily managed. Furthermore efforts are necessary before the beneficial effects observed in trials have a real impact in clinical practice. A broader view and priority for the management of this syndrome on a national level are needed to improve the quality of heart failure care in Portugal.

    Thelazia callipaeda (Spirurida, Thelaziidae) is a nematode that lives in the conjunctival sac of domestic and wild carnivores, rabbits and humans causing mild to severe symptoms (e.g., conjunctivitis, lacrimation, epiphora, blepharospasm, keratitis and even corneal ulceration) in infected animals. This report describes an autochthonous case of thelaziosis in a cat from the central region of Portugal, representing the most occidental record of thelaziosis in Europe. Adult nematodes recovered from alive animal were morphological identified as T. callipaeda. A portion of the mitochondrial cytochrome c oxidase subunit 1 gene (cox 1) from nematode specimens was amplified by PCR. Cox1 sequences of all specimens were identical to T. callipaeda haplotype 1. Additionally to these findings, a recent description of thelaziosis in the northern region of Portugal suggests that T. callipaeda has successfully established in Portugal.

    Due to globalized migratory processes, female genital mutilation/cutting (FGM/C) has spread to other countries, including countries in Europe, where, with a few exceptions, it remains a concealed problem. To the authors' knowledge, this is the first national extensive study to estimate the prevalence of FGM/C in Portugal. Prevalence estimation. Using extrapolation of country-of-origin prevalence data and the 2011 Census data, this study estimated: the prevalence of FGM/C in Portugal among women of reproductive age (15-49 years) and among all women aged ≥15 years; and the number of girls aged <15 years living in Portugal who have undergone or will probably undergo FGM/C. It is estimated that 6576 women aged ≥15 years living in Portugal have undergone FGM/C, with cases distributed unevenly throughout the national territory. In addition, it is estimated that 1830 girls aged <15 years living in Portugal have undergone or are likely to undergo FGM/C. This study estimated that more than 6000 women living in Portugal have undergone FGM/C, and many girls remain at risk. These two groups need different types of interventions. Awareness of the number and geographical dispersion of cases of FGM/C will enable more informed and targeted definition of public health policies for protection of females who have undergone or are at risk of undergoing FGM/C.

  3. Crustal structure beneath Portugal from teleseismic Rayleigh Wave Ellipticity

    Up until now, Portugal lacked a countrywide shear velocity model sampling short length-scale crustal structure, which limits interpretations of seismicity and tectonics, and predictions of strong ground motion. In turn, such interpretations and predictions are important to help mitigate risk of destruction from future large on- and offshore earthquakes similar to those that Portugal has experienced in the past (e.g. the Mw 8.5-8.7 tsunamigenic event in 1755). In this study, we measured teleseismic Rayleigh Wave Ellipticity (RWE) from 33 permanent and temporary seismic stations in Portugal with wave periods between 15 s and 60 s, and inverted it for 1-D models of shear wave velocity (Vs) structure beneath each station using a fully non-linear Monte Carlo method. Because RWE is strongly sensitive to the uppermost few kilometres of the crust, both RWE measurements and Vs models are spatially correlated with surface geology in Portugal. For instance, we find that sedimentary basins produced by rifting that had begun in the Mesozoic such as the Lusitanian Basin (LB) and the Lower Tagus-Sado Basin (LTSB) are characterised by higher RWE (lower Vs). Interestingly, we observe similar RWE (and Vs) values in the interior of the Central Iberian Zone (CIZ), which is a metamorphic belt of Paleozoic age. Together with reduced crustal thickness previously estimated for the same parts of the CIZ, this suggests that the CIZ might have experienced an episode of extension possibly simultaneous to Mesozoic rifting. The Galicia-Tras-os-Montes-Zone (GTMZ) that has undergone polyphased deformation since the Paleozoic is characterised by the lowest RWE (highest Vs) in Portugal. Ossa Morena Zone and the South Portuguese Zone exhibit intermediate Vs values when compared to that of basins and the GTMZ. Our crustal Vs model can be used to provide new insights into the tectonics, seismicity and strong ground motion in Portugal.

An on-line survey was sent by email including questions about characteristics of national, regional and local health transport systems, vehicles, material, and composition of the transport team and their training. Hospital pediatric healthcare professionals treating children in Spain, Portugal and Latin America RESULTS: A total of 117 surveys from 15 countries were analyzed. Of them, 55 (47%) come from 15 regions of Spain and the rest from Portugal and 13 Latin American countries. The inter-hospital transport of pediatric patients is unified only in the Spanish regions of Baleares and Cataluña and in Portugal. Chile has a mixed unified transport system for pediatric and adult patients. Only 51.4% of responders have an educational program for the transport personnel, and only in 36.4% of them the educational program is specific for pediatric patients. In Spain and Portugal the transport is executed mostly by public entities, while in Latin America public and private systems coexist. Specific pediatric equipment is more frequent in the transport teams in the Iberian Peninsula than in Latin American teams. The specific pediatric transport training is less frequent for teams in Latin America than on Spain and Portugal. There is a great variation in the organization of children transport in each country and region. Most of countries and cities do not have unified and specific teams of pediatric transport, with pediatric qualified personnel and specific material.

    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.

    Although adverse effects of suggestive interviewing on children's accuracy are well documented, it remains unclear as to whether these effects vary depending on the valence of and the actor implicated in suggestions. In this study, 124 3-8-year-olds participated in a classroom activity and were later questioned about positive and negative false details. The interviewer provided positive reinforcement when children acquiesced to suggestions and negative feedback when they did not. Following reinforcement or feedback, young children were comparably suggestible for positive and negative details. With age, resistance to suggestions about negative details emerged first, followed by resistance to suggestions about positive details. Across age, more negative feedback was required to induce acquiescence to negative than positive false details. Finally, children were less willing to acquiesce when they (versus the confederate) were implicated. Findings highlight the interactive effects of valence and children's age on their eyewitness performance in suggestive contexts.

  8. Ship Finds and Their Management as Actor Network

    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.

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

    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.

    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.

    Social status is an important predictor of poor health. Most studies of this issue have focused on the lower echelons of society. To determine whether the increase in status from winning an academy award is associated with long-term mortality among actors and actresses. Retrospective cohort analysis. Academy of Motion Picture Arts and Sciences. All actors and actresses ever nominated for an academy award in a leading or a supporting role were identified (n = 762). For each, another cast member of the same sex who was in the same film and was born in the same era was identified (n = 887). Life expectancy and all-cause mortality rates. All 1649 performers were analyzed; the median duration of follow-up time from birth was 66 years, and 772 deaths occurred (primarily from ischemic heart disease and malignant disease). Life expectancy was 3.9 years longer for Academy Award winners than for other, less recognized performers (79.7 vs. 75.8 years; P = 0.003). This difference was equal to a 28% relative reduction in death rates (95% CI, 10% to 42%). Adjustment for birth year, sex, and ethnicity yielded similar results, as did adjustments for birth country, possible name change, age at release of first film, and total films in career. Additional wins were associated with a 22% relative reduction in death rates (CI, 5% to 35%), whereas additional films and additional nominations were not associated with a significant reduction in death rates. The association of high status with increased longevity that prevails in the public also extends to celebrities, contributes to a large survival advantage, and is partially explained by factors related to success.

  13. Men and family planning in Portugal.

    Although family planning services in Portugal are open to everybody, male and female, and they are free of charge, it is mostly women who are using the services, since family planning services have integrated maternal health care. Between 1978 and 1981, the Commission for the Portuguese Commission for Equality and Women's Rights implemented a family planning information, education, and communication project under technical and financial aid by the United Nations Population Fund. During a training course for a group of 12 women, which took place in the small town Vialonga near Lisbon in 1992, all women said that their husbands did not play any role in family planning. The choice of the method was their sole responsibility. In 1988, data were gathered by the General Direction of Primary Health Care from the local health services. 17.6% of women used the pill, and 28% practiced coitus interruptus. Condom use amounted to 5.7%. Other methods were the IUD (7.3%), natural methods (3.6%), spermicides (2.6%), the diaphragm (0.3%), and sterilization (female 3.6%; male 0.3%). In 1992, the Commission published a study on family planning, involving 638 men and 882 women, which concluded that the responsibility for family planning was no longer exclusively with women and that young, single people were in favor of family planning information sessions. The Portuguese Constitution states that the state shall promote a wider knowledge of family planning methods and responsible parenthood. The Health Secretary of State ordered the integration of family planning into the National Health Service in 1976. A 1984 law, Sex Education and Family Planning, and a 1985 Government Order constitute the legal framework for the practice of family planning. The Commission for Equality and Women's Rights has been implementing information, education, and communication activities since 1976. One of the members of the Consultative Council is the Association for Family Planning, which has also been

    Icosahedral nucleo-cytoplasmic large DNA viruses (NCLDV)-like viruses, which forminclusions in the erythrocyte cytoplasm of reptiles, were previously presented as candidates for a new genus of the Iridoviridae family. The present work describes the distribution of infected lizard hosts and ultrastructural characteristics of the viral inclusions of NCLDV-like viruses from Portugal and adjacent locations in Spain. Giemsa-stained blood smears of 235 Lacerta schreiberi from Portugal and Spain, 571 Lacerta monticola from the mountain Serra da Estrela (Portugal), 794 Podarcis hispanica from several localities in Portugal and Spain, and 25 Lacerta dugesii from Madeira Island, were studied. Infection in L. schreiberi was only found in mountain populations, up to 30% in Serra da Estrela and 9-11% elsewhere. It was absent in lizards from lowlands. Prevalence of infection among L. monticola in Serra da Estrela was 10%; infected lizards were found during March to July and October but not in August and September. Infection in P. hispanica was below 3.3%. Only one infected specimen of L. dugesii was identified by light microscopy. Ultrastructural examination of infected samples revealed that the inclusions are virus assembly sites of icosahedral cytoplasmic iridovirus-like virions. Virions from different host species have different ultrastructural features and probably represent different related viruses.

    2016-02-01

    Although several studies have reported an increase of syphilis incidence over the last decade in Western Europe, information concerning syphilis epidemiology in Portugal remains scarce. Therefore, we sought to characterise acquired syphilis-associated hospitalisations in Portugal according to demographic and clinical data. We used a database containing all hospitalisations that occurred in mainland Portugal public hospitals with discharges between 2000 and 2014. We analysed all hospitalisations associated with ICD-9-CM codes 091-097.x (corresponding to acquired syphilis diagnosis) concerning inpatients' gender, age and comorbidities. The median length of stay and in-hospital mortality rates were also studied. Between 2000 and 2014, there were a total of 8974 syphilis-related hospitalisations in mainland Portugal. The rate of acquired syphilis hospitalisations per 100,000 inhabitants increased by 33 % during the studied period. Syphilis hospitalisation rates increased by 70 % in males and 139 % among patients aged over 55 years. On the other hand, they declined by 10 % in females and 20 % among patients younger than 55 years old. The percentage of syphilis episodes presenting cardiovascular and neuropsychiatric comorbidities increased, while the percentage of syphilis episodes presenting HIV co-infection decreased by 69 %. A fatal outcome was reported in 5 % of episodes; 4.6 % of them had acquired syphilis as the main reason for hospitalisation. This study illustrates that, despite being a preventable infection, syphilis remains a public health problem. The analysis of hospitalisation and administrative data helps to understand syphilis epidemiology and provides a supplement to traditional case notifications.

  3. Diversity of Cercopithifilaria species in dogs from Portugal

    PubMed Central

    2014-01-01

    Background Filarioids belonging to the genus Cercopithifilaria (Spirurida: Onchocercidae) have been described in dogs in association with Rhipicephalus sanguineus group ticks, which act as their biological vectors. This study represents the first investigation on Cercopithifilaria spp. in dogs from Portugal. Findings Dogs (n = 102) from the Algarve region (south of Portugal) were sampled by skin snip collection and tissues were left to soak overnight in saline solution. Sediments were observed under a light microscope and the detected microfilariae identified according to their morphology. Twenty-four dogs (23.5%) were found infected with at least one species of Cercopithifilaria, namely C. bainae (9.8%), C. grassii (3.9%) and Cercopithifilaria sp. II sensu Otranto et al., 2013 (13.7%). Results were confirmed by molecular amplification of partial cytochrome c oxidase subunit I and 12S rRNA genes and sequence analysis. Co-infections with more than one Cercopithifilaria species were detected in 3.9% of the animals. Conclusions This is the first report of Cercopithifilaria spp. in dogs from Portugal. The estimated level of infection with C. bainae, C. grassii and Cercopithifilaria sp. II suggests that these filarioids are prevalent in the canine population of southern Portugal. PMID:24898125

    Mota, Ana; Areias, Jorge; Cardoso, Margarida Fonseca

    2011-01-01

    Infection with Hepatitis B is a public health problem worldwide. In Portugal, around 1% of the population is chronically infected. Some genotypes are only predominant in some geographical regions; however migration around the world can lead to the dissemination of the different genotypes. The heterogeneity of hepatitis B genotypes seems to be related to differences in clinical evolution of the infection and response to antiviral treatment. The present study was designed to review the worldwide geographical distribution of Hepatitis B genotypes, and to analyze the possible relationships with the distribution of genotypes in Portugal. Studies of interest were identified by search on indexed journals. Search of Portuguese information was extended to conference proceedings in the areas of Virology and Hepatology. In Asia genotypes B and C were prevalent; in the North of Africa the genotype D was prevalent, and in the East Coast genotype E was predominant. In the American continent the most predominant genotypes were A, D, F, G and H. In South America, Venezuela and Argentina showed a high prevalence of genotype F, in Brazil genotype A was prevalent. In Europe, including Portugal, genotypes A and D were predominant. In Portugal genotypes C, E and F were observed in Portuguese patients and in immigrant patients. The pattern of global migration affects the pattern of genotype distribution, introducing genotypes in regions where the clinical outcome can differ from the population of origin. The genotypic distribution found in Portugal seems to be associated not just with being a European country, but also with immigration from Africa, Brazil, Eastern Europe, and Asian countries like China. The study of the hepatitis B genotypic distribution should be extended to all regions in Portugal, namely Lisbon where the immigration levels are higher, as well as to the autonomous regions of Portugal, the Azores and Madeira islands. The relationship between hepatitis B genotypes and

    The assessment of climate change impacts on viticulture is often carried out using regional climate model (RCM) outputs. These studies rely on either multi-model ensembles or on single-model approaches. The RCM-ensembles account for uncertainties inherent to the different models. In this study, using a 16-RCM ensemble under the IPCC A1B scenario, the climate change signal (future minus recent-past, 2041-2070 - 1961-2000) of 4 bioclimatic indices (Huglin Index - HI, Dryness Index - DI, Hydrothermal Index - HyI and CompI - Composite Index) over mainland Portugal is analysed. A normalized interquartile range (NIQR) of the 16-member ensemble for each bioclimatic index is assessed in order to quantify the ensemble uncertainty. The results show significant increases in the HI index over most of Portugal, with higher values in Alentejo, Trás-os-Montes and Douro/Porto wine regions, also depicting very low uncertainty. Conversely, the decreases in the DI pattern throughout the country show large uncertainties, except in Minho (northwestern Portugal), where precipitation reaches the highest amounts in Portugal. The HyI shows significant decreases in northwestern Portugal, with relatively low uncertainty all across the country. The CompI depicts significant decreases over Alentejo and increases over Minho, though decreases over Alentejo reveal high uncertainty, while increases over Minho show low uncertainty. The assessment of the uncertainty in climate change projections is of great relevance for the wine industry. Quantifying this uncertainty is crucial, since different models may lead to quite different outcomes and may thereby be as crucial as climate change itself to the winemaking sector. This work is supported by European Union Funds (FEDER/COMPETE - Operational Competitiveness Programme) and by national funds (FCT - Portuguese Foundation for Science and Technology) under the project FCOMP-01-0124-FEDER-022692.

  6. Employment and basic needs: lessons of a mission to Portugal.

    PubMed

    Van Rijckeghem, W

    1978-01-01

    The task of the International Labour Organization (ILO) mission that visited Portugal in 1977 differed in several respects from that of earlier missions undertaken in the framework of the World Employment Programme: 1) with a per capita consumption of U.S. $1000 a year, Portugal is far better off than the other countries to which ILO missions were sent; 2) following the Revolution of April 25, 1974, Portugal had already adopted many of the recommendations such as those concerning income redistribution and land reform contained in the reports of earlier ILO missions; and 3) as a consequence of the above, the ILO mission to Portugal was not asked to produce a report and make recommendations, but to participate directly in the drafting of the 1977-80 Plan through a joint Portuguese-ILO Working Group. The present article draws both on the report of the Working Group and on subsequent research. Open unemployment is a recent phenomenon in Portugal, and the objective of the Medium-Term Plan is to improve basic-needs satisfaction and reduce unemployment. It can be reasonably assumed that the increased activity of the agricultural sector, together with continued north-south migration, will absorb much of the existing underemployment. Concerning industry, the reorientation of industrial growth towards the requirements of a basic-needs strategy and more employment-intensive production represents a considerable change from past strategies and policies. Concerning the basic-needs approach as a development strategy, it is useful to show that such a strategy remains compatible with the pursuit of more traditional objectives, such as sustained growth, full employment, balance-of-payments equilibrium, equitable income distribution, and harmonious regional development.

    Introdução: Tem havido baixa adesão ao padrão da dieta mediterrânica na população portuguesa. Nesta perspectiva, procedemos à revisão crítica do estado de nutrição das mulheres em idade fértil, grávidas e recém-nascidos, em Portugal. Material e Métodos: Realizámos uma revisão narrativa crítica de estudos recentes com qualidade e inquéritos nacionais oficiais, que tivessem avaliado a dieta e estado de nutrição de mulheres em idade fértil e de grávidas portuguesas e sua influência no estado de nutrição dos respetivos fetos e recém-nascidos. Resultados: Foram selecionados e analisados cinco estudos ecológicos multinacionais que incluíram Portugal, dois inquéritos oficiais nacionais sobre disponibilidade de alimentos, sete estudos nacionais sobre dieta e estado de nutrição de mulheres em idade fértil e grávidas e cinco estudos nacionais sobre a influência de fatores nutricionais maternos no crescimento dos fetos. A prevalência de excesso de peso/obesidade em mulheres em idade fértil e grávidas aumentou substancialmente associada à diminuição da adesão à dieta mediterrânica. As variações no consumo de energia e macronutrientes na gravidez parecem não ter impacto significativo no estado de nutrição dos fetos. Pelo contrário, o excesso de peso/obesidade pré-concecional associa-se a aumento de adiposidade ao nascer e o excessivo aumento de peso na gravidez associa-se ao excesso ponderal na infância. Os fatores potencialmente relacionados com a baixa adesão à dieta mediterrânica, merecendo futura investigação, incluem políticas agrícolas da União Europeia que promoveram a produção de grupos alimentares não tipicamente mediterrânicos a baixo preço e a pouca capacidade financeira referida pela população portuguesa para aquisição de alimentos de qualidade. Conclusão: A recuperação dos hábitos dietéticos mediterrânicos tradicionais deve ser incluída em estratégias de prevenção e tratamento do

  8. Reassembling the Social - An Introduction to Actor-Network-Theory

    NASA Astrophysics Data System (ADS)

    Latour, Bruno

    2005-09-01

    Reassembling the Social is a fundamental challenge from one of the world's leading social theorists to how we understand society and the 'social'. Bruno Latour's contention is that the world 'social' as used by Social Scientists has become laden with assumptions to the point where it has become misnomer. When the adjective is applied to a phenomenon, it is used to indicate a stabilized state of affairs, a bundle of ties that in due course may be used to account for another phenomenon. But Latour also finds the word used as if it described a type of material, in a comparable way to an adjective such as 'wooden' or 'steely'. Rather than simply indicating what is already assembled together, it is now used in a way that makes assumptions about the nature of what is assembled. It has become a word that designates two distinct things: a process of assembling: and a type of material, distinct from others. Latour shows why 'the social' cannot be thought of as a kind of material or domain, and disputes attempts to provide a 'social explanation' of other states of affairs. While these attempts have been productive (and probably necessary) in the past, the very success of the social sciences mean that they are largely no longer so. At the present stage it is no longer possible to inspect the precise constituents entering the social domain. Latour returns to the original meaning of 'the social' to redefine the notion and allow it to trace connections again. It will then be possible to resume the traditional goal of the social sciences, but using more refined tools. Drawing on his extensive work examining the 'assemblages' of nature, Latour finds it necessary to scrutinize thoroughly the exact content of what is assembled under the umbrella of Society. This approach, a 'sociology of associations' has become known as Actor-Network-Theory, and this book is an essential introduction both for those seeking to understand Actor-Network-Theory, or the ideas of one of its most

    Díaz-Castro, Lina; Arredondo, Armando; Pelcastre-Villafuerte, Blanca Estela; Hufty, Marc

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

    Introdução: Dada a crescente incidência da diabetes tipo 2 e considerando que parte do seu controlo se deve à atitude do pacienteface à doença, torna-se importante munir os profissionais de saúde com ferramentas capazes de determinar as carências educacionais dos utentes, permitindo uma intervenção mais personalizada na correção de hábitos nocivos. Objetivos: Verificação da fiabilidade da Escala de Conhecimentos da Diabetes em Portugal. Análise e correlação das diferentes variáveis sociodemográficas e patológicas com o número de respostas corretas. Material e Métodos: Aplicação da escala a uma amostra de conveniência de diabéticos tipo 2 do Centro de Saúde da Covilhã.Resultados: Na generalidade, as questões obtiveram um valor de alfa de Cronbach > 0,800. Diabéticos com melhores resultados demonstraram maior controlo, estabelecendo uma relação positiva entre o conhecimento e o controlo da diabetes. Apenas 9,2% dos diabéticos apresentou bom conhecimento sobre a doença, sendo que a maioria (65,8%) demonstrou um conhecimento mediano. Os insulinotratados exibiram os piores resultados (77,6% com baixo conhecimento). As variáveis ‘via de tratamento’ e ‘complicações’ demonstraram ter impacto no desempenho obtido no questionário (valores p iguais a 0,00 e 0,048, respetivamente). Os diabéticos rurais, os sem complicações e os não insulinotratados revelaram-se os mais cumpridores e conhecedores. Discussão: Contrariando estudos anteriores, variáveis como a idade e o grau de escolaridade não demonstraram influenciar o conhecimentodo diabético. Habitantes do meio rural e diabéticos tratados oralmente obtiveram melhores resultados do que o que havia sido defendido previamente. Conclusão: Demonstrou-se a fidelidade psicométrica moderada a elevada do teste, assim como uma correlação positiva entre o controloda diabetes e o desempenho no inquérito. Espera-se que a sua futura aplicação possibilite identificar as

  8. Detecting, measuring, and testing dyadic patterns in the actor-partner interdependence model.

    2010-06-01

    Family researchers have used the actor-partner interdependence model (APIM) to study romantic couples, parent-child dyads, and siblings. We discuss a new method to detect, measure, and test different theoretically important patterns in the APIM: equal actor and partner effect (couple pattern); same size, but different signs of actor and partner effects (contrast pattern); and zero partner effects (actor-only pattern). To measure these different patterns, as well as others, we propose the estimation of the parameter k, which equals the partner effect divided by the actor effect. For both indistinguishable dyad members (e.g., twins) and distinguishable dyad members (e.g., heterosexual couples), we propose strategies for estimating and testing different models. We illustrate our new approach with four data sets. (c) 2010 APA, all rights reserved.

  9. A decoupled graph/computation data-driven architecture with variable-resolution actors

    SciTech Connect

    Evripidou, P.; Gaudiot, J.L.

    1990-12-31

    This paper presents a hybrid multiprocessor architecture that combines the advantages of the dynamic data-flow principles of execution with those of the control-flow model of execution. Two major design ideas are utilized by the proposed model: asynchronous execution of graph and computation operations, and variable- resolution actors. The independence of the two main unites of the machine allows an efficient implementation of functional/data-flow principles with conventional, mature technology. The compiler generates graphs with variable-sized actors in order to match the characteristics of the application to the target machine. For instance, vector actors are proposed for many aspects of scientific computing, while lower resolution (Compound Macro Actors) or conversely higher resolution (atomic instruction actors) is used for unvectorizable programs.

    2015-05-01

    Stochastic actor-based models for network dynamics have the primary aim of statistical inference about processes of network change, but may be regarded as a kind of agent-based models. Similar to many other agent-based models, they are based on local rules for actor behavior. Different from many other agent-based models, by including elements of generalized linear statistical models they aim to be realistic detailed representations of network dynamics in empirical data sets. Statistical parallels to micro-macro considerations can be found in the estimation of parameters determining local actor behavior from empirical data, and the assessment of goodness of fit from the correspondence with network-level descriptives. This article studies several network-level consequences of dynamic actor-based models applied to represent cross-sectional network data. Two examples illustrate how network-level characteristics can be obtained as emergent features implied by micro-specifications of actor-based models.

    People convey their emotional state in their face and voice. We present an audio-visual data set uniquely suited for the study of multi-modal emotion expression and perception. The data set consists of facial and vocal emotional expressions in sentences spoken in a range of basic emotional states (happy, sad, anger, fear, disgust, and neutral). 7,442 clips of 91 actors with diverse ethnic backgrounds were rated by multiple raters in three modalities: audio, visual, and audio-visual. Categorical emotion labels and real-value intensity values for the perceived emotion were collected using crowd-sourcing from 2,443 raters. The human recognition of intended emotion for the audio-only, visual-only, and audio-visual data are 40.9%, 58.2% and 63.6% respectively. Recognition rates are highest for neutral, followed by happy, anger, disgust, fear, and sad. Average intensity levels of emotion are rated highest for visual-only perception. The accurate recognition of disgust and fear requires simultaneous audio-visual cues, while anger and happiness can be well recognized based on evidence from a single modality. The large dataset we introduce can be used to probe other questions concerning the audio-visual perception of emotion. PMID:25653738

    Background. In the German movie “Vincent will Meer” a healthy actor portrays a man with Tourette's syndrome. Objective. The aim of this study was to investigate whether the performance of tics is convincing and whether this judgment depends on whether he/she suffers from tics or not. Methods. While the movie was broadcasted in German cinemas, we put an online survey (including 28 questions on different aspects related to the observation, performance, and authenticity of tics) on the web pages of the German self-help group. 276/296 surveys submitted could be used for further analyses. Results. 95.7% of all participants felt that the performance of tics was convincing. However, people with tics (n = 26) were less convinced compared to those who had never met a person with tics (n = 110) (P = 0.020). Conclusions. Our results further support the hypothesis that tics are not “abnormal” but “physiological” movements that are only misplaced both in time and context. PMID:24895487

  14. Two routes to actorhood: lexicalized potency to act and identification of the actor role.

    PubMed

    Frenzel, Sabine; Schlesewsky, Matthias; Bornkessel-Schlesewsky, Ina

    2015-01-01

    The inference of causality is a crucial cognitive ability and language processing is no exception: recent research suggests that, across different languages, the human language comprehension system attempts to identify the primary causer of the state of affairs described (the "actor") quickly and unambiguously (Bornkessel-Schlesewsky and Schlesewsky, 2009). This identification can take place verb-independently based on certain prominence cues (e.g., case, word order, animacy). Here, we present two experiments demonstrating that actor potential is also encoded at the level of individual nouns (a king is a better actor than a beggar). Experiment 1 collected ratings for 180 German nouns on 12 scales defined by adjective oppositions and deemed relevant for actorhood potential. By means of structural equation modeling, an actor potential (ACT) value was calculated for each noun. Experiment 2, an event-related potential study, embedded nouns from Experiment 1 in verb-final sentences, in which they were either actors or non-actors. N400 amplitude increased with decreasing ACT values and this modulation was larger for highly frequent nouns and for actor versus non-actor nouns. We argue that potency to act is lexically encoded for individual nouns and, since it modulates the N400 even for non-actor participants, it should be viewed as a property that modulates ease of lexical access (akin, for example, to lexical frequency). We conclude that two separate dimensions of actorhood computation are crucial to language comprehension: an experience-based, lexically encoded (bottom-up) representation of actorhood potential, and a prominence-based, computational mechanism for calculating goodness-of-fit to the actor role in a particular (top-down) sentence context.

    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.

    NASA Astrophysics Data System (ADS)

    Walsh, Nathan William

    Changes in the climatic stasis of the planet have been observed for many years and these changes are at last having an impact on the perceived security of the planet as a whole. The causes of these changes are linked generally to the emission of gasses emitted by the burning of hydrocarbons for the production of energy. The shift toward less intensive hydrocarbon use and more non-emitting sources of energy appear to be driven by a popular desire for action from populations. Among the many examples of renewable energy development Portugal stands out as a shining example of great development in a short period of time. Whether that development has been caused by popular demand within the state or due to political processes within the state or political influences external to the state is important to understand so that similar results can be replicated throughout the world.

    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.

    This article analyzes how both the Portuguese state and civil society have addressed the AIDS issue, focusing on participation by the lesbian, gay, bisexual, and transsexual community (LGBT) in the struggle against AIDS. The article begins by describing the situation of LGBT individuals in Portugal during the 1990s, when the Portuguese LGBT movement emerged and grew, and then characterizes the evolution of HIV/AIDS in Portugal, analyzing the relationship between civil society and sexuality in general and the situation of the epidemic in the country in particular, considering key facts, nongovernmental organizations, and state initiatives. Special attention is given to the role played by LGBT organizations in the struggle against HIV. Finally, the article reflects on the future of the struggle against both AIDS and discrimination in the 21st century, considering recent events in the country and the guidelines recommended by international policies.

    The first case of cutaneous leishmaniosis in a horse from the north of Portugal, with a 1.5 cm in diameter ulcerated nodular lesion on the left face, is reported. The skin nodule was surgically excised and assessed by histopathology, including an immunohistochemistry method applied for the first time to equine tissues which clearly demonstrated leishmanial amastigote forms. Two serological determinations with the direct agglutination test performed 13 months apart showed seroconversion specific for Leishmania from a <25 to a 200 antibody titre. Polymerase chain reaction followed by kinetoplast DNA sequencing provided a 116-bp sequence with 98% identity to Leishmania infantum closest sequence deposited in GenBank. No recurrence was observed after complete surgical excision. Leishmaniosis should be included in the differential diagnosis of cutaneous nodular or papular lesions in the equine species in Portugal.

    Borrelia miyamotoi, a relapsing fever spirochete, has been found recently in Ixodes ricinus ticks; however, little is known about its spatial distribution and potential local impact on human health. A total of 640 ticks (447 nymphs and 193 adults) collected throughout Portugal were analyzed using two nested PCR protocols, one targeting the flagellin gene and the other the internal transcribed space region between the 5S and the 23S rRNA. As a result, B. miyamotoi was detected, for the first time, in one guesting I. ricinus nymph collected in the Lisboa district. In addition, a prevalence of 11% (71/640) for B. burgdorferi sensu lato was obtained. Even though no human relapsing fever cases due to infection by B. miyamotoi have been reported yet in Portugal, surveillance must be improved to provide better insight into the prevalence and distribution of this spirochete in ticks.

    Cutaneous loxoscelism is an exceptional diagnosis in Portugal, regardless of the documented presence of Loxosceles rufescens.We report a 33-year old female patient presenting to our clinic after having visualized a bite from a spider in the inner aspect of the right thigh. Afterwards, she developed a warm, painful erythematous plaque, progressing to skin necrosis and torpid ulcer formation. Considering the failure of conservative measures, surgical debridement of the ulcer followed by repair using an O-Z plasty achieved good functional outcome. Definite diagnosis of cutaneous loxoscelism may be difficult since it relies on the visualization of the bite, capture of the spider for identification and typical clinical features. This case meets several criteria that allow the establishment of a causative link between spider bite and dermonecrosis. It is, to the best of our knowledge, the first diagnosis of loxoscelism reported in Portugal.

    In line with the growing concern around the world about construction and demolition waste (CDW) management, an attempt has been made to quantify the amount of CDW generated in Portugal, a country where no reliable/official data exist. This is an increasingly important concern of companies, businesses and municipalities involved with CDW, in a context of rising demands and more demanding recent legislation. One methodology is presented to quantify the present generation, and another to extrapolate this generation over the next few years, up to 2020. It is concluded that at present substantially less CDW is generated than the figure usually cited for Portugal, based on Spanish estimates, although it is predicted that this value will be higher on a 10-15 year timescale, reaching over 400 kg person⁻¹ year⁻¹.

  4. Deterring Asymmetric Threats from Sub-State Actors

    SciTech Connect

    Homsy, R V

    2002-01-31

    Deterrence means preventing another's actions by influencing their decisionmaking process. Nuclear deterrence was successfully accomplished during the Cold War by holding the adversary's valuable assets at risk by targeting them with nuclear weapons, a policy known as mutually assured destruction (MAD). In this case neither player attacks the other, because the ultimate outcome is self-destruction. Deterrence based upon MAD is largely ineffective against sub-state actors who may have few if any assets, the location of which may be unknown. Furthermore, the threat of destroying their assets may only serve to strengthen their motivation to do more stealthy violence, the threat being interpreted as a taunt. The key to establishing deterrence is understanding the adversary's decision process, starting with the factors upon which decisions are made, called decision attributes. Asymmetric threats are assumed to involve chemical, biological, radiological, or nuclear (CBRN) weapons. So, the key decision attributes here are concerned with the acquisition and use of CBRN weapons. We have identified the following five countermeasure objectives for establishing deterrence: (1) Reduce access to CBRN weapons, expertise, materials, and equipment; (2) Make CBRN weapons difficult to use; (3) Reduce the effectiveness of CBRN weapons; (4) Increase the likelihood of being caught acquiring and using CBRN weapons; and (5) Establish a policy of retribution for acquiring and using CBRN weapons. It should be emphasized that an adversary's perception toward these objectives is most important in affecting their decisionmaking. Of course each adversary will respond differently toward these countermeasures, depending upon their motivations, objectives, preferences, resources, and willingness to gamble. Motivation of violence is defined as the fundamental cause or driving force; absent which the intent to do violence no longer exists. Correct understanding of motivations requires adapting your

    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.

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

    This study aimed to identify the actor and partner effects of self-efficacy, marital adjustment, and social support on the health promoting behavior of Korean pregnant couples. Participants were 132 couples who met the eligibility criteria. Data were collected from June to November, 2016 at a community health center. The Actor-Partner Interdependence Model was used for analyzing the actor and partner effects of self-efficacy, marital adjustment, and social support on health promoting behavior. The fitness indices for the model were GFI=0.90, NFI=0.92, CFI=0.91, TLI=0.90, and RMSEA=0.04, which satisfied the criteria. Self-efficacy had actor and partner effect on health promoting behavior of wives, but had only actor effect of on health promoting behavior of husbands. Marital adjustment showed actor and partner effect on the health promoting behavior of pregnant couples. Social support only had an actor effect on the health promoting behavior of wives. And, marital adjustment and social support had a mutual effect. This study indicates that the partner involvement is needed to develop health promotion programs for pregnant couples.

    This paper presents the implementation of scientific programs on a decoupled data-driven architecture with vectors and macro actors. This hybrid multiprocessor combines the dynamic data-flow principles of execution with the control-flow of the von Neumann model of execution. The two major ideas utilized by the decoupled model are: Vector and macro actors with variable resolution, and asynchronous execution of graph and computation operations. The compiler generates graphs with various-sized actors in order to match the characteristics of the computation. For instance, vector actors are proposed for many aspects of scientific computing while lower resolution (complier-generated collection of scalar actors) or higher resolution (scalar actors) is used for unvectorizable programs. A block-scheduling technique for extracting more parallelism from sequential constructs is incorporated in the decoupled architecture. In addition a graph-level priority-scheduling mechanism is implemented that improves resource utilization and yields higher performance. A graph unit executes all graph operations and a computation unit executes all computation operations. The independence of the two main units of the machine allows the efficient pipelined execution of macro actors with diverse granularity characteristics.

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

    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.

  14. Two routes to actorhood: lexicalized potency to act and identification of the actor role

    PubMed Central

    Frenzel, Sabine; Schlesewsky, Matthias; Bornkessel-Schlesewsky, Ina

    2015-01-01

    The inference of causality is a crucial cognitive ability and language processing is no exception: recent research suggests that, across different languages, the human language comprehension system attempts to identify the primary causer of the state of affairs described (the “actor”) quickly and unambiguously (Bornkessel-Schlesewsky and Schlesewsky, 2009). This identification can take place verb-independently based on certain prominence cues (e.g., case, word order, animacy). Here, we present two experiments demonstrating that actor potential is also encoded at the level of individual nouns (a king is a better actor than a beggar). Experiment 1 collected ratings for 180 German nouns on 12 scales defined by adjective oppositions and deemed relevant for actorhood potential. By means of structural equation modeling, an actor potential (ACT) value was calculated for each noun. Experiment 2, an event-related potential study, embedded nouns from Experiment 1 in verb-final sentences, in which they were either actors or non-actors. N400 amplitude increased with decreasing ACT values and this modulation was larger for highly frequent nouns and for actor versus non-actor nouns. We argue that potency to act is lexically encoded for individual nouns and, since it modulates the N400 even for non-actor participants, it should be viewed as a property that modulates ease of lexical access (akin, for example, to lexical frequency). We conclude that two separate dimensions of actorhood computation are crucial to language comprehension: an experience-based, lexically encoded (bottom–up) representation of actorhood potential, and a prominence-based, computational mechanism for calculating goodness-of-fit to the actor role in a particular (top–down) sentence context.

  15. History of Astronomy in Portugal: Theories, Institutions and Practices

    NASA Astrophysics Data System (ADS)

    Saraiva, Luis

    2014-01-01

    In Portugal, throughout its history, astronomy was developed in the context of the mathematical sciences. During the times of Portugal's Maritime Discoveries, astronomical navigation was based on spherical trigonometry, and therefore it was the mathematicians who taught astronomy to the pilots. During the 17th century, basic notions of astronomy were taught in mathematical courses in the University and in the main Jesuit colleges. This tradition continued in the 18th century, so it is no wonder that one of the most influent Portuguese astronomers during this period was the mathematician José Monteiro da Rocha. During the 19th century the new centres of science teaching, as the Polytechnic School in Lisbon, or the Polytechnic Academy in Oporto, developed astronomy teaching and research in the context of the mathematics subjects. The inheritors of these 19th century institutions, respectively the Faculties of Sciences of Lisbon and Oporto, upheld this tradition until the final decades of 20th century and continued to consider astronomy as a subject to be taught in their mathematics departments. This Meeting aims at outlining several perspectives on the history of astronomy in Portugal, particularly analysing its ties with mathematical sciences and astronomy applications. The Meeting is organised by the Museum of Science of the University of Lisbon (MCUL) with CMAF, CMUC, CMUP and the CIUHCT, and is included in CIM events. It is integrated in the commemorations of the International Year of Astronomy (IYA2009).

  16. Regulation of clinical research and bioethics in Portugal.

    2007-06-01

    This article presents an overview of the Portuguese transposition of the European Directive on Good Clinical Practice (2001/20/E) concerning scientific and academic debates on bioethics and clinical investigation. Since the Directive was transposed into Portuguese law by its National Assembly, the bureaucracy of clinical trials has been ever more complex. Despite demands for swift application processes by the Pharmaceutical industry, supported by the European Parliament, the Directive's transcription to the national law has not always delivered the expected outcome. However, this has led to an increased number of applications for clinical trials in Portuguese hospitals. In this article I revise bioethical publications and decree-laws enabling an informed appraisal of the anxieties and prospects for the implementation of the clinical trials Directive in Portugal. This article also places the European Directive in the field of sociology of bioethics, arguing that Portuguese bioethical institutions differ from those of the US, and also from Northern European counterparts. The main divergence is that those people in Portugal who claim expertise in 'legal' bioethics do not dominate either the bureaucratic structure of research or ethics committees for health. Even experts in the applied ethics field now claim that 'professional bioethicists do not exist'. The recent creation of a national Ethics Committee for Clinical Investigation (CEIC) in line with the European Directive on Good Clinical Practice (GCP) will not change the present imbalance between different professional jurisdictions in the national bioethical debate in Portugal.

    This study was carried out to determine chewing louse species of wild birds in the Ria Formosa Natural Park, located in southern Portugal. In addition, the hypothesis that bird age, avian migration and social behaviour have an impact on the louse prevalence was tested. Between September and December of 2013, 122 birds (belonging to 10 orders, 19 families, 31 genera and 35 species) captured in scientific ringing sessions and admitted to the Wildlife Rehabilitation and Investigation Centre of Ria Formosa were examined for lice. Twenty-six (21.3%) birds were found to be infested with at least one chewing louse species. The chewing lice identified include 18 species. Colonial birds (34.9%) and migratory birds (29.5%) had statistically significant higher prevalence than territorial birds (6.8%) and resident birds (13.1%), respectively. This paper records 17 louse species for the first time in southern Portugal: Laemobothrion maximum, Laemobothrion vulturis, Actornithophilus piceus lari, Actornithophilus umbrinus, Austromenopon lutescens, Colpocephalum heterosoma, Colpocephalum turbinatum, Eidmanniella pustulosa, Nosopon casteli, Pectinopygus bassani, Pseudomenopon pilosum, Trinoton femoratum, Trinoton querquedulae, Craspedorrhynchus platystomus, Degeeriella fulva, Falcolipeurus quadripustulatus, Lunaceps schismatus. Also a nymph of the genus Strigiphilus was collected from a Eurasian eagle-owl. These findings contribute to the knowledge of avian chewing lice from important birds areas in Portugal.

    The EQ-5D is a preference-based measure widely used in cost-utility analysis (CUA). Several countries have conducted surveys to derive value sets, but this was not the case for Portugal. The purpose of this study was to estimate a value set for the EQ-5D for Portugal using the time trade-off (TTO). A representative sample of the Portuguese general population (n = 450) stratified by age and gender valued 24 health states. Face-to-face interviews were conducted by trained interviewers. Each respondent ranked and valued seven health states using the TTO. Several models were estimated at both the individual and aggregated levels to predict health state valuations. Alternative functional forms were considered to account for the skewed distribution of these valuations. The models were analyzed in terms of their coefficients, overall fit and the ability for predicting the TTO values. Random effects models were estimated using generalized least squares and were robust across model specification. The results are generally consistent with other value sets. This research provides the Portuguese EQ-5D value set based on the preferences of the Portuguese general population as measured by the TTO. This value set is recommended for use in CUA conducted in Portugal.

    Atmospheric circulation classifications are not a simple description of atmospheric states but a tool to understand and interpret the atmospheric processes and to model the relation between atmospheric circulation and surface climate and other related variables (Radan Huth et al., 2008). Classifications were initially developed with weather forecasting purposes, however with the progress in computer processing capability, new and more robust objective methods were developed and applied to large datasets prompting atmospheric circulation classification methods to one of the most important fields in synoptic and statistical climatology. Classification studies have been extensively used in climate change studies (e.g. reconstructed past climates, recent observed changes and future climates), in bioclimatological research (e.g. relating human mortality to climatic factors) and in a wide variety of synoptic climatological applications (e.g. comparison between datasets, air pollution, snow avalanches, wine quality, fish captures and forest fires). Likewise, atmospheric circulation classifications are important for the study of the role of weather in wildfire occurrence in Portugal because the daily synoptic variability is the most important driver of local weather conditions (Pereira et al., 2005). In particular, the objective classification scheme developed by Trigo and DaCamara (2000) to classify the atmospheric circulation affecting Portugal have proved to be quite useful in discriminating the occurrence and development of wildfires as well as the distribution over Portugal of surface climatic variables with impact in wildfire activity such as maximum and minimum temperature and precipitation. This work aims to present: (i) an overview the existing circulation classification for the Iberian Peninsula, and (ii) the results of a comparison study between these atmospheric circulation classifications based on its relation with wildfires and relevant meteorological

  1. Actors conform, observers react: the effects of behavioral synchrony on conformity.

    PubMed

    Dong, Ping; Dai, Xianchi; Wyer, Robert S

    2015-01-01

    Engaging in synchronous behavior can induce a more general disposition to copy others, which increases the tendency to conform to others' preferences in an unrelated choice situation. In contrast, observing others perform synchronous behavior can induce psychological reactance and decrease conformity to others' preferences. Five experiments confirmed these different effects and circumscribed the conditions in which they occurred. Actors typically focus their attention on the goal to which their synchronous behavior is directed, inducing a copying-others mindset that generalizes to later situations. In contrast, observers focus on the actors' behavior independently of the goal to which it pertains. Consequently, they become sensitive to the restrictions on freedom that synchronous behavior requires and experience reactance. However, changing the relative attention that actors and observers pay to these factors can reverse the effects of the actors' synchronous behavior on conformity.

    This paper presents an overview of a virtual actor system composed of several subsystems designed to automate some of these animation tasks. Our emphasis is on the facial animation of virtual actors. The paper specifically details the situations processor component of the framework, which is a major building block in the automatic virtual actor system. An expert system using a fuzzy knowledge-based control system is used to realize the automated system. Fuzzy linguistic rules are used to train virtual actors to know the appropriate emotions and gestures to use in different situations of a synthetic movie, the higher level parameters of which are provided by human directors. Theories of emotion, personality, dialogue, and acting, as well as empirical evidence is incorporated into our framework and knowledge bases to produce promising results.

    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.

  4. Matching safety to access: global actors and pharmacogovernance in Kenya- a case study.

    2017-03-23

    The Kenyan government has sought to address inadequacies in its National Pharmaceutical Policy and the Pharmacy and Poisons Board's (PPB) medicines governance by engaging with global actors (e.g. the World Health Organization). Policy actors have influenced the way pharmacovigilance is defined, how challenges are understood and which norms are requisite to address drug safety issues. In this paper, we investigate the relationship between specific modes of engagement among global (exogenous) and domestic actors at the national and sub-national level to identify the positive or negative effect on pharmacovigilance and pharmacogovernance in Kenya. Pharmacogovernance is defined as the manner in which governing structures; policy instruments; institutional authority (e.g., ability to act, implement and enforce norms, policies and processes) and resources are managed to promote societal interests for patient safety and protection from adverse drug reactions (ADRs). Qualitative research methods that included key informant interviews and document analysis, were employed to investigate the relationship between global actors' patterns of engagement with national actors and pharmacogovernance in Kenya. Global actors' influence on pharmacogovernance and pharmacovigilance priorities in Kenya (e.g., legislation and adverse drug reaction surveillance) was positively perceived by key informants. We found that global actors' engagement with state actors produced positive and negative outcomes. Engagement with the PPB and Ministry of Health (MOH) that was characterized as dependent (advocacy, empowerment, delegated) or interdependent (collaborative, cooperative, consultative) was mostly associated with positive outcomes e.g., capacity building; strengthening legislation and stakeholder coordination. Fragmentation (independent engagement) hindered risk communication between public, private, and NGO health programs. A framework for assessing pharmacogovernance would support policy

    There is a limited body of research on how the actual social exchange among workplace actors influences the practice of return-to-work. The objective of this study was to explore how workplace actors experience social relations at the workplace and how organizational dynamics in workplace-based return-to-work extends before and beyond the initial return of the sick listed worker to the workplace. An exploratory qualitative method approach was used, consisting of individual open-ended interviews with 33 workplace actors at seven worksites that had re-entering workers. The workplace actors represented in these interviews include: re-entering workers, supervisors, co-workers, and human resource managers. The analysis identified three distinct phases in the return to work process: while the worker is off work, when the worker returns back to work, and once back at work during the phase of sustainability of work ability. The two prominent themes that emerged across these phases include the theme of invisibility in relation to return-to-work effort and uncertainty, particularly, about how and when to enact return-to-work. The findings strengthen the notion that workplace-based return-to-work interventions need to take social relations amongst workplace actors into account. They also highlight the importance and relevance of the varied roles of different workplace actors during two relatively unseen or grey areas, of return-to-work: the pre-return and the post-return sustainability phase. Attention to the invisibility of return-to-work efforts of some actors and uncertainty about how and when to enact return-to-work between workplace actors can promote successful and sustainable work ability for the re-entering worker.

    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.

    People often take either the role of an actor or that of recipient in positive and negative interpersonal events when they interact with others. The present study investigated how the actor-recipient role affected the neural responses to self in emotional situations. Twenty-five participants were scanned while they were presented with positive and negative interpersonal events and were asked to rate the degree to which the actor/the recipient was that kind of person who caused the interpersonal event. Half of the trials were self-relevant events and the other half were other-relevant events. Results showed that people were more likely to isolate self from negative events when they played the role of actor relative to recipient. Pregenual anterior cingulate cortex (pgACC) and posterior dorsal anterior cingulate cortex (pdACC) were more active for self than other only in negative events. More importantly, also in negative interpersonal events, dorsal medial prefrontal cortex (dmPFC) showed greater self-related activations (self-other) when participants played the role of recipient relative to actor, while activities in orbitofrontal cortex (OFC) were greater for self than other only when the evaluation target played the role of recipient. These results showed that the actor-recipient role affected neural responses to self in emotional situations, especially when a recipient role was played in negative situations. PMID:25926781

    Two experiments demonstrated that eyewitnesses more frequently associate an actor with the actions of another person when those two people had appeared together in the same event, rather than in different events. This greater likelihood of binding an actor with the actions of another person from the same event was associated with high-confidence recognition judgments and “remember” responses in a remember–know task, suggesting that viewing an actor together with the actions of another person led participants to falsely recollect having seen that actor perform those actions. An analysis of age differences provided evidence that familiarity also contributed to false recognition independently of a false-recollection mechanism. In particular, older adults were more likely than young adults to falsely recognize a novel conjunction of a familiar actor and action, regardless of whether that actor and action were from the same or from different events. Older adults’ elevated rate of false recognition was associated with intermediate confidence levels, suggesting that it stemmed from increased reliance on familiarity rather than from false recollection. The implications of these results are discussed for theories of conjunction errors in memory and of unconscious transference in eyewitness testimony. PMID:23722927

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

    People often take either the role of an actor or that of recipient in positive and negative interpersonal events when they interact with others. The present study investigated how the actor-recipient role affected the neural responses to self in emotional situations. Twenty-five participants were scanned while they were presented with positive and negative interpersonal events and were asked to rate the degree to which the actor/the recipient was that kind of person who caused the interpersonal event. Half of the trials were self-relevant events and the other half were other-relevant events. Results showed that people were more likely to isolate self from negative events when they played the role of actor relative to recipient. Pregenual anterior cingulate cortex (pgACC) and posterior dorsal anterior cingulate cortex (pdACC) were more active for self than other only in negative events.

    2008-12-01

    Mistakes in eyewitness identification frequently occur when incorrect associations are made between a familiar person and the actions of another person. The present research demonstrates that actors do not need to be similar in appearance for such conjunction errors to occur. The actors can, in fact, be very different in appearance, even of different sexes. Participants attempted to remember a series of brief everyday events, each involving an actor performing an action. Increases in actor similarity led to increases in conjunction errors in which participants incorrectly associated a familiar actor with a familiar action that was actually performed by someone else, but conjunction errors frequently occurred even when the familiar actor was of a different sex than the original actor, arguing against the hypothesis that these conjunction errors are due solely to mistaken identity.

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

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

    Former coastal estuaries in the Algarve region of South Portugal are used for reconstruction coastal evolution since first marine transgression processes at about 8.000 years before. The sediments of these archives allow high resolution analyses of geochemical and palynological signals. Drillings in different lagoons of the Algarve region contain the sequences from the fluvial sediments during the early Holocene, marine transgression facies during the middle Holocene and the marine/fluvial sediment deposits until present. The results of the sedimentological, geochemical and palynological analyses show that each estuary developed differently, depending on the morphology of the paleovalley, environmental conditions and especially the influence of the sea and the formation of barrier systems. The estuaries were flooded between 7500 and 5500 cal a BP by sea level rise and were almost completely filled by sediment by the beginning of the Roman occupation (226 y BC / 2176 cal a BP). A clear change in sedimentological processes is evident in the estuaries between 5500 and 3000 cal a BP and is interpreted as a result of high energy events such as storms or tsunamis (Schneider et al. 2009, Hilbich et al. 2008 ). Palynological as well as archaeological investigations show distinct anthropogenic influences since 3500 cal. BP by increasing values in maquies, cereals and open land communities.

  6. A review of leptospirosis in farm animals in Portugal.

    This paper presents a review of Leptospira infection in farm animals in Portugal which is based mainly on serological results obtained in the National Veterinary Research Laboratory between January 1987 and December 1993. Serum samples were tested by the microscopic agglutination test, at a minimum dilution of 1:100. Positive titres were obtained in 15.3% of the 9,543 bovine samples examined. Sejroe, Pomona, Hebdomadis, Tarassovi and Icterohaemorrhagiae were the principal serogroups which reacted in the tests. A total of 3,195 pigs were tested, of which 20.2% showed positive reactions. The main serogroups which reacted were Australis, Pomona, Cynopteri, Icterohaemorrhagiae and Autumnalis. Field observations on outbreaks of leptospirosis in pigs, along with data obtained from an experimental infection with serovar mozdok in pregnant gilts suggest that this serovar, rather than serovar pomona, may be causing Pomona group infections in pigs. Serum samples from 5,298 sheep were tested and 3.3% gave positive results. The predominant serogroups involved were Canicola, Pomona, Cynopteri, Sejroe and Icterohaemorrhagiae. From the 1,631 goats examined serologically, 5.0% gave positive results, mainly to serogroups Grippotyphosa, Canicola, Pomona, Icterohaemorrhagiae and Pyrogenes. Only 83 serum samples from horses were obtained, of which 43.4% showed positive titres. Serogroups Australis, Autumnalis, Cynopteri and Pyrogenes were those most commonly found. Serological evidence of leptospirosis in farm animals is widespread in Portugal, particularly in cattle and pigs. Leptospirosis in horses needs to be studied further. In an attempt to provide a general view on the occurrence of leptospirosis in these animal species in Portugal, the present results are compared with results obtained in previous studies and are complemented with both previous and recent bacteriological findings.

  7. Determinants of birth weight in Portugal: 1988 to 2011.

    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.

    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.

    An objective classification scheme, as developed by Trigo and DaCamara (2000), was applied to classify the daily atmospheric circulation affecting Portugal between 1980 and 2007 into a set of 10 basic weather types (WTs). The classification scheme relies on a set of atmospheric circulation indices, namely southerly flow (SF), westerly flow (WF), total flow (F), southerly shear vorticity (ZS), westerly shear vorticity (ZW) and total vorticity (Z). The weather-typing approach, together with surfacemeteorological variables (e.g. intensity and direction of geostrophic wind, maximum and minimum temperature and precipitation) were then associated to wildfire events as recorded in the official Portuguese fire database consisting of information on each fire occurred in the 18 districts of Continental Portugal within the same period (>450.000 events). The objective of this study is to explore the dependence of wildfire activity on weather and climate and then evaluate the potential of WTs to discriminate among recorded wildfires on what respects to their occurrence and development. Results show that days characterised by surface flow with an eastern component (i.e. NE, E and SE) account for a high percentage of daily burnt area, as opposed to surface westerly flow (NW, W and SW), which represents about a quarter of the total number of days but only accounts for a very low percentage of active fires and of burnt area. Meteorological variables such as minimum and maximum temperatures, that are closely associated to surface wind intensity and direction, also present a good ability to discriminate between the different types of fire events..

    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

    We have analyzed the spatial and temporal variability of chlorophyll in the Atlantic Ocean off the Portugal coast using satellite imagery from 1979 to 1986 in conjunction with wind data. The spatial patterns in the imagery show the typical inshore-offshore and east-west gradients, while the temporal patterns show seasonal high winter values and low summer values. In the satellite imagery for the period 1979-1986, stable mesoscale and large scale patterns recurred despite interannual differences in absolute satellite-derived pigment concentrations.

    This study aimed to assess the care received and the barriers faced by immigrants and Portuguese pregnant women in Portugal. This is an exploratory qualitative study, resorting to applying semi-structured interviews to 60 immigrant and 22 Portuguese women. Content analysis supported by QSR Nvivo10 program was used. The study was approved by an Ethics Committee. The results showed four categories related to affective dimensions-relational, cognitive, technical-instrumental and health care policy for pregnant women. As for the barriers in health care, these were mentioned by some of the expectant mothers, especially immigrant women. Almost all, both immigrant and Portuguese, pregnant women were satisfied with the health care.

  14. Not My Problem: Vicarious Conflict Adaptation with Human and Virtual Co-actors

    2016-01-01

    The Simon effect refers to an incompatibility between stimulus and response locations resulting in a conflict situation and, consequently, slower responses. Like other conflict effects, it is commonly reduced after repetitions, suggesting an executive control ability, which flexibly rewires cognitive processing and adapts to conflict. Interestingly, conflict is not necessarily individually defined: the Social Simon effect refers to a scenario where two people who share a task show a conflict effect where a single person does not. Recent studies showed these observations might converge into what could be called vicarious conflict adaptation, with evidence indicating that observing someone else's conflict may subsequently reduce one's own. While plausible, there is reason for doubt: both the social aspect of the Simon Effect, and the degree to which executive control accounts for the conflict adaptation effect, have become foci of debate in recent studies. Here, we present two experiments that were designed to test the social dimension of the effect by varying the social relationship between the actor and the co-actor. In Experiment 1, participants performed a conflict task with a virtual co-actor, while the actor-observer relationship was manipulated as a function of the similarity between response modalities. In Experiment 2, the same task was performed both with a virtual and with a human co-actor, while heart-rate measurements were taken to measure the impact of observed conflict on autonomous activity. While both experiments replicated the interpersonal conflict adaptation effects, neither showed evidence of the critical social dimension. We consider the findings as demonstrating that vicarious conflict adaptation does not rely on the social relationship between the actor and co-actor. PMID:27199839

    The increase in prevalence of Salmonella 1,4,[5],12:i:- related infections over the last few years has been considered a public health issue in many European countries, especially as this serovar may be associated with tetraresistance to ampicillin, streptomycin, sulfonamides, and tetracyclines (R-type ASSuT). Salmonella 1,4,[5],12:i:- isolates (n = 187) obtained by the Portuguese National Laboratory from different sources, including human clinical cases (n = 170), veterinary (n = 10), environmental (n = 6), and food samples (n = 1), were collected from 15 districts between 2006 and 2011. All isolates were serotyped using the slide agglutination method and results were confirmed by multiplex PCR for the monophasic variant. From the confirmed Salmonella 1,4,[5],12:i:-, R-type ASSuT isolates were selected by disc diffusion and minimal inhibitory concentration (MIC) determination for further characterization by pulsed-field gel electrophoresis restriction with XbaI, virulence genes determination by PCR, additional antimicrobial resistance profiling by disc diffusion, and epidemiological distribution evaluation. Out of the 187 serotyped isolates, 133 were confirmed as Salmonella 1,4,[5],12:i:- with a R-type ASSuT occurrence of 61.7%. Distribution among Portuguese districts showed a higher percentage of reported cases in coastal areas, in particular, in Porto (24.8%), Setúbal (13.5%), and Aveiro (12.8%), probably due to the higher population density. Clonality analysis revealed a high diversity of pulsotypes with the majority of human salmonellosis cases being attributed to sporadic events. All isolates harbored 14 out of the 18 virulence genes evaluated and 87.8% of the isolates showed all the resistance genes frequently associated with the European clone, blaTEM(+)sul2(+)straA-straB(+)tetB(+). This study shows that Salmonella 1,4,[5],12:i:- resistant isolates are widely distributed in Portugal. This may be related to a selective advantage offered

    African horse sickness (AHS) was diagnosed for the first time in southern Portugal in autumn 1989, following outbreaks in Spain. AHS virus presence was confirmed by virus isolation and serotyping. An eradication campaign with four sanitary zones was set up by Central Veterinary Services in close collaboration with private organizations. Vaccination began on 6 October. In February 1990, vaccination was extended to all Portuguese equines (170000 animals). There were 137 outbreaks on 104 farms: 206 of the equidae present died (16%) or were slaughtered (14%); 81.5% were horses, 10.7% were donkeys and 7.8% were mules. Clinical AHS occurred more frequently in horses than donkeys and mules. In the vaccinated population, 82 animals (62.2% horses and 37.8% mules and donkeys), died or were slaughtered due to suspected or confirmed AHS. One year after ending vaccination, December 1991, Portugal was declared free of AHS. Cost of eradication was US$1955513 (US$11.5/Portuguese equine). PMID:10579455

    Cardiovascular disease is the leading cause of morbidity, mortality and disability in Portugal. Socioeconomic level is known to influence health status but there is scant evidence on socioeconomic inequalities in cardiovascular disease in Portugal. To analyze the distribution of cardiovascular disease in the Portuguese population according to socioeconomic status. We conducted a cross-sectional study using data from the fourth National Health Survey on a representative sample of the Portuguese population. Socioeconomic inequalities in cardiovascular disease, risk factors and number of medical visits were analyzed using odds ratios according to socioeconomic status (household equivalent income) in the adult population (35-74 years). Comparisons focused on the top and bottom 50% and 10% of household income distribution. Of the 21 807 individuals included, 53.3% were female, and mean age was 54 ± 11 years. Cardiovascular disease, stroke, ischemic heart disease, hypertension, diabetes, obesity and physical inactivity were associated with lower socioeconomic status, while smoking was associated with higher status; number of medical visits and psychological distress showed no association. When present, inequality was greater at the extremes of income distribution. The results reveal an association between morbidity, lifestyle and socioeconomic status. They also suggest that besides improved access to effective medical intervention, there is a need for a comprehensive strategy for health promotion and disease prevention that takes account of individual, cultural and socioeconomic characteristics.

    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.

  19. Competition policy for health care provision in Portugal.

    We review the role of competition among healthcare providers in Portugal, which has a public National Health Service (NHS) at the core of the health system. There is little competition among healthcare providers within the NHS. Competition among NHS primary care providers is hindered by excess demand (many residents in Portugal do not have a designated family doctor). Competition among NHS hospitals has been traditionally limited to cases of maximum guaranteed waiting time for surgery being exceeded. The Portuguese Competition Authority enforces competition law. It has focused on mergers between private hospitals and abuse of market power (including cartel cases) by private healthcare providers. The Healthcare Regulation Authority produced several reports on particular areas of activity by private healthcare providers. The main conclusion of these reviews was lack of conditions for effective competition, with the exception of dentistry. Within the NHS, the use of tendering procedures was able to create "competition for the market" in particular areas though it was not problem free. Details in the particular design adopted matter a lot. Overall, the scope for competition policy and for competition among healthcare providers to have a main role in a health system based on a public National Health Service seems limited, with more relevance to "competition for the market" situations than to "competition in the market".

    Since the very first ages, human beings have attempted to understand and manage their environment in order to survive. This is the case regarding wildlife, weather cycles and gathering periods. This is also reflected in the areas surrounding sites where individuals live; they changed the landscape with different aims. This type of archaeology has risen very recently - in the last few years - and is usually called Landscape Archaeology. Traditional landscape archaeology has dealt with earth and location related studies; the relationship of ancient peoples with the sky has been disregarded. The archaeoastronomical studies have mitigated this fact. Archaeoastronomy has revealed an important number of archaeological sites; many of them reveal a clear intention of astronomically designed buildings or structures. This implies a planned detailed design and obviously a deep understanding of astronomical knowledge. As examples of these sites a number of megalithic ditched enclosures sited in Portugal will be shown which were studied inside the project "Ditched enclosures plants and Neolithic cosmologies: A landscape, archaeoastronomical and geophysical perspective". The ideological and astronomical aspects inside the architecture of these types of sites will be explained. In this paper we present a new methodology applied in the archaeoastronomical calculations for southern Portugal sites. It includes GIS techniques and the development of an archaeoastronomical layer that can be used to display the computations over cartographic information from the archaeological sites. A Spatial Data Infrastructure is also created in order to expose the results.

    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.

    An overview of the large-scale atmospheric forcing on the occurrence of cloud-to-ground lightning activity over Portugal is presented here. A dataset generated by a network of nine sensors, maintained by the Portuguese Meteorological Institute (four sensors) and by Spanish Meteorological Agency (five sensors), with available data over the 2003-2009 time period (7 years) is used for this purpose. For the same time period, a state-of-the-art high-resolution reanalysis dataset in a 1.0° latitude × 1.0° longitude grid (Modern Era Retrospective - Analysis for Research and Applications; MERRA300) is also considered in order to assess the atmospheric large-scale features over the target region. Three lightning regimes of the atmospheric general circulation within the Euro-Atlantic sector can be clearly detected. These regimes are characterized according to their underlying dynamical conditions (sea surface pressure, 500 hPa geopotential height and air temperature, streamlines of the 10 m wind vectors, and best 4-layer lifted index at 500 hPa). The spatial distribution of lighting activity in Portugal (patterns of the density of the atmospheric electrical discharges) is also analyzed for each regime separately. Considerations regarding seasonality, flash polarity and daily cycles in the lighting activity are also given for each lightning regime.

    The Portuguese Meteorological Institute (IM), operates regular and non-regular programmes of upper-air observations using balloons and radiosondes for measuring meteorological variables and atmospheric ozone concentration. The regular programmes consists in daily observations of upper-air pressure, temperature, humidity and wind using balloons and electronic radiosondes, carried out at 3 fixed stations in Portugal, which reach more than 30 km of altitude. IM has also 2 portable systems that are occasionally used for temporary observations during field campaigns, which have been taken several times in different regions of Portugal. The radiosondes used include electrical sensors for the PTU measurements and GPS-module for balloon tracking, which signals are used for wind computation at the ground station. Except for the Azores station, where helium is used, the balloons at all other sites are filled with hydrogen. There are also non-regular programmes that have been carried out weekly for the observation of the vertical profile of ozone up to about 35 km of altitude, using 1200 grams balloons and "Brewer-Mast" ozonesondes.

    Air Liquide will spend $18 million to build a naphtha steam reforming unit in Estarreja, Portugal that will produce 3,700 cu meters/hour of hydrogen (H{sub 2}). The new plant will raise Air Liquide`s H{sub 2} capacity at the site to 8,000 cu meters/hour. The company supplies Anilina de Portugal with H{sub 2}. In addition, Air Liquide supplies Dow Chemical with carbon monoxide used in its methylene di-para-phenylene isocyanate plant at the site. Anilina is spending Esc1.8 billion ($11.3 million) to expand aniline capacity from 60,000 m.t./year to 95,000 m.t./year by the end of 1997 and nitrobenzene from 100,000 m.t./year to 170,000 m.t./year. This year Dow will buy more than 50,000 m.t./year of aniline from the Portuguese firm for its MDI production.

    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.

    Developmental Biology has established itself as a solid field of teaching and research in Portugal. Its history is recent, generally considered to have started with the pioneering work of Augusto Celestino da Costa at the beginning of the 20th century. However, research groups were very few and, until the early 1990s, teaching beyond morphological and comparative embryology was uncommon. In 1994, the first university course dedicated to Developmental Biology as a separate field from Embryology was created at the Faculty of Sciences of the University of Lisbon and a course on Plant Differentiation and Morphogenesis was also initiated. A Masters programme in Developmental Biology followed at the Lusofona University in 1996. Subsequently, modules of Developmental Biology were included in many Embryology courses and eventually more Developmental Biology courses were created. From 1999 onwards, the number of research groups working in Developmental Biology started to increase, many of which were initiated by researchers who had had the opportunity to pursue their PhD and/or post-doc studies abroad. The Instituto Gulbenkian de Cincia (Gulbenkian Institute of Science) became the first home of most of these groups, but several later spread to other institutions. This increased activity in turn has stimulated teaching of Developmental Biology and more students have been getting interested in the field. This positive feedback loop makes it a nice time to be teaching and working in Developmental Biology in Portugal.

    Medico-legal entomology, one area in the broad field of entomology, is routinely used in forensic applications. Insects are often collected from a corpse during criminal information related to the body, but requires the fast and accurate identification of the species attracted to the remains. The local entomofauna in most cases is important for explaining entomological evidence. The survey of the local entomofauna has become a fundamental first step in forensic entomological studies, because different geographical distributions, seasonal and environmental factors may influence the decomposition process and the occurrence of different species on corpses. A morphological and DNA-based methods for species identification were used in this study. Thirty-two cases are reported from indoors and outdoors conditions. Specimens were collected from corpses during autopsy procedures in the National Institute of Legal Medicine, Portugal, and cases were summarized by sex, death local, month of discovery, probable cause of death, species found and number of analyzed specimens. Just eight species, mainly Calliphoridae together with one Sarcophagidae were reported from corpses. The DNA sequencing was performed to study the mitochondrial encoded subunit I of the cytochrome oxidase gene. The aim of this work was the beginning of a database of the cadaveric entomofauna in Portugal.

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

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

    Decentralisation and other public policies have created public spaces for participation in most Latin-American countries where community representatives, together with municipal authorities and other public functionaries, decide on social investment plans, including health services and infrastructure. The municipal development council system constitutes such public space in Guatemala. This study analysed such system's governance in a sample of 6 rural municipalities. A descriptive design was used, applying qualitative and quantitative techniques to study three central categories: the strategic actors, the rules of the game and power asymmetry levels amongst actors. The findings revealed inconsistencies amongst the actors who had to participate according to the legal framework and those actors who actually did so in practice. Divergent interests were also identified for participating which affected the possibility of reaching consensus during decision-making. Analysing the rules of the game led to identifying formal and non-formal mechanisms favouring some actors' ability to influence decisions. Analysing power asymmetry levels led to identifying that community representatives had fewer power resources than institutional representatives (local government and other government organisations). Community representatives also face different barriers blocking their participation and perceive a lesser capacity to influence decision-making. Existing barriers and fewer power resources experienced by community representatives reduce their abilities to influence decision-making in municipal development councils.

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

    Life satisfaction has been linked to lower cardiovascular disease mortality. However, much less is known about the biological mechanisms linking life satisfaction to physical health. In addition, the dyadic context of life satisfaction has not been considered despite increasing evidence that partners influence each other in health-relevant ways. These questions were addressed with 94 married couples who completed measures of life satisfaction and had their blood drawn for determination of interleukin-6 (IL-6) and C-reactive protein (CRP). Actor-partner models showed that higher actor levels of life satisfaction predicted lower levels of IL-6 and CRP (p's < .05), whereas partner levels of life satisfaction did not predict any measure of inflammation. The actor results were not mediated by marital satisfaction or health behaviors. Finally, no actor × partner interactions were significant and these links were not moderated by marital satisfaction. These data highlight inflammation as a potentially important biological mechanism linking actor reports of life satisfaction to lower cardiovascular mortality.

    Stochastic actor-based models for network dynamics have the primary aim of statistical inference about processes of network change, but may be regarded as a kind of agent-based models. Similar to many other agent-based models, they are based on local rules for actor behavior. Different from many other agent-based models, by including elements of generalized linear statistical models they aim to be realistic detailed representations of network dynamics in empirical data sets. Statistical parallels to micro-macro considerations can be found in the estimation of parameters determining local actor behavior from empirical data, and the assessment of goodness of fit from the correspondence with network-level descriptives. This article studies several network-level consequences of dynamic actor-based models applied to represent cross-sectional network data. Two examples illustrate how network-level characteristics can be obtained as emergent features implied by micro-specifications of actor-based models. PMID:25960578

    Rainfall is the most important physical process responsible for the landslide triggering in Portugal. Following the work of Zêzere et al. (2014), we present the state of the art concerning the proposition of empirical rainfall thresholds in Portugal for different types of landslides observed in different zones of the country: the Lisbon region, the Douro Valley and the NW Mountains, and the Povoação Municipality in São Miguel Island (Azores). The empirical thresholds applied in Portugal are based on the identification of 120 landslide events and include (i) the computation of antecedent rainfall threshold defined by linear regression, (ii) the normalization of rainfall by the mean annual precipitation, (iii) the definition of combined rainfall thresholds, which integrates the rainfall event and the antecedent rainfall for different time periods, and (iv) the definition of lower limit and upper limit rainfall thresholds. The intensity-duration (ID) threshold is the empirical rainfall threshold more used worldwide. In mainland Portugal, the highest ID rainfall threshold is registered in the NW Mountains, which is the rainiest zone of the country. The Lisbon Region typically receives less rain per year and the corresponding ID threshold is lower than that obtained in the north part of the country. The Povoação study area evidence a contrasting situation, which is associated to the highest value of the negative exponential of the threshold (-0.66). As a consequence, for short duration (< 10 h) this threshold is only exceeded in the NW Mountains, while for long durations (>1,000 h) it is below the remaining thresholds. The normalization of the ID threshold by the mean annual precipitation (MAP) has showed that, in relative terms: (i) the ID threshold is highest in Lisbon Region for duration less than 50 h; (ii) in the north of the country, the ID threshold is more exigent in the Douro Valley than in the NW Mountains and (iii) the ID threshold in Povoa

    Dietary intake has changed considerably in South European countries, but whether those changes were similar between countries is currently unknown. To assess the trends in food availability in Portugal and four other Mediterranean countries from 1966 to 2003. Food and Agricultural Organization food balance sheets from Portugal, France, Italy, Greece and Spain. Trends were assessed by linear regression. The per capita availability of calories has increased in Portugal, France, Greece, Italy and Spain in the past 40 years. Portugal presented the most rapid growth with an annual increase of 28.5 +/- 2.2 kcal (slope +/- standard error), or +1000 kcal overall. In animal products, Portugal had an annual increase of 20.7 +/- 0.9 kcal, much higher than the other four countries. Conversely, the availabilities of vegetable and fruit only showed a slight growth of 1.0 +/- 0.1 kcal/year and 2.5 +/- 0.4 kcal/year, respectively, thus increasing the ration of animal to vegetable products. Olive oil availability increased in all countries with the notable exception of Portugal, where a significant decrease was noted. Wine supply decreased in all five countries; in contrast, beer supply started to take up more alcohol share. Percentage of total calories from fat increased from nearly 25% to almost 35% in Portugal during the study period, mainly at the expenses of calories from carbohydrates, whereas the share of protein showed just a slight increase. Furthermore, fat and protein were increasingly provided by animal products. Portugal is gradually moving away from the traditional Mediterranean diet to a more Westernized diet as well as France, Greece, Italy and Spain. Noticeably, the trends of diet transition were observed relatively faster in Portugal than in the other four Mediterranean countries.

    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.

  17. At what age do children learn to discriminate between act and actor?

    2001-02-01

    Children's ability to make moral judgements about an act on the basis of aspects of the act rather than on liking and preconceived ideas about the actor was investigated. 85 children of 4 age groups (preschool, Grades 1, 2, and 3, age range 5-9 years) participated. Act/Actor discrimination was investigated with a test consisting of 8 cartoons. In 4, a rabbit was behaving aggressively against a wolf; the other 4 portrayed identical acts with the wolf as aggressor and the rabbit as victim. Participants made moral evaluations of each cartoon. IQ was measured with Raven's Standard Progressive Matrices, and the general level of moral development was measured in accord with Piaget's (1932) criteria. Age, IQ, and general moral development correlated with discriminative ability for Act and Actor. In Piagetian terms, children at the heteronomous level were not capable of such discrimination, while children at the autonomous level (above 7 years of age) in general were.

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

The estimated occurrence of immunogobulin G (IgG) antibodies against SBV in sheep of Portugal was 12.8% (95% confidence interval 11.0-15.0%). This is the first study reporting the presence of SBV antibodies in sheep of Portugal.

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

    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.

  2. Formal Specification and Validation of a Hybrid Connectivity Restoration Algorithm for Wireless Sensor and Actor Networks †

    Maintaining inter-actor connectivity is extremely crucial in mission-critical applications of Wireless Sensor and Actor Networks (WSANs), as actors have to quickly plan optimal coordinated responses to detected events. Failure of a critical actor partitions the inter-actor network into disjoint segments besides leaving a coverage hole, and thus hinders the network operation. This paper presents a Partitioning detection and Connectivity Restoration (PCR) algorithm to tolerate critical actor failure. As part of pre-failure planning, PCR determines critical/non-critical actors based on localized information and designates each critical node with an appropriate backup (preferably non-critical). The pre-designated backup detects the failure of its primary actor and initiates a post-failure recovery process that may involve coordinated multi-actor relocation. To prove the correctness, we construct a formal specification of PCR using Z notation. We model WSAN topology as a dynamic graph and transform PCR to corresponding formal specification using Z notation. Formal specification is analyzed and validated using the Z Eves tool. Moreover, we simulate the specification to quantitatively analyze the efficiency of PCR. Simulation results confirm the effectiveness of PCR and the results shown that it outperforms contemporary schemes found in the literature.

  3. Multivariate cluster analysis of forest fire events in Portugal

    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

    Wildfires in the Mediterranean region have severe damaging effects mainly due to large fire events [1, 2]. When restricting to Portugal, wildfires have burned over 1:4 million ha in the last decade. Considering the increasing tendency in the extent and severity of wildfires [1, 2], the availability of modeling tools of fire episodes is of crucial importance. Two main types of mathematical models are generally available, namely deterministic and stochastic models. Deterministic models attempt a description of fires, fuel and atmosphere as multiphase continua prescribing mass, momentum and energy conservation, which typically leads to systems of coupled PDEs to be solved numerically on a grid. Simpler descriptions, such as FARSITE, neglect the interaction with atmosphere and propagate the fire front using wave techniques. One of the most important stochastic models are Cellular Automata (CA), in which space is discretized into cells, and physical quantities take on a finite set of values at each cell. The cells evolve in discrete time according to a set of transition rules, and the states of the neighboring cells. In the present work, we implement and then improve a simple and fast CA model designed to operationally simulate wildfires in Portugal. The reference CA model chosen [3] has the advantage of having been applied successfully in other Mediterranean ecosystems, namely to historical fires in Greece. The model is defined on a square grid with propagation to 8 nearest and next-nearest neighbors, where each cell is characterized by 4 possible discrete states, corresponding to burning, not-yet burned, fuel-free and completely burned cells, with 4 possible rules of evolution which take into account fuel properties, meteorological conditions, and topography. As a CA model, it offers the possibility to run a very high number of simulations in order to verify and apply the model, and is easily modified by implementing additional variables and different rules for the

    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

    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

    Introdução: Nos últimos anos, vários autores evidenciaram a morbilidade associada aos partos ocorridos entre as 34 e 36 semanas (pré-termo tardio) e entre as 37 e 38 semanas de gestação (termo precoce). Neste sentido, pretendemos realizar um estudo epide-miológico dos partos que ocorrem nestas idades gestacionais, em Portugal. Material e Métodos: Realizámos um inquérito, que foi aplicado a todos os hospitais públicos de Portugal, acerca da prevalência e via de parto nos partos pré-termo tardios e de termo precoce, e morbilidade e mortalidade neonatal associada. As questões referiam-se apenas a gestações de feto único e a partos ocorridos em 2013. Resultados: Incluímos 14 hospitais, correspondendo a 33,5% dos partos ocorridos em Portugal, em 2013. Verificámos que 5,4% dos partos ocorreram no período pré-termo tardio e 27% no termo precoce. Aproximadamente dois terços dos partos pré-termo tardio e três quartos dos partos de termo precoce foram espontâneos. A taxa de cesariana foi mais elevada entre as 34 e 36 semanas de gestação (39,1%) do que entre as 37 e 38 semanas (26,4%). As complicações neonatais foram mais frequentes após um parto pré-termo tardio (34,2%), quando comparadas com os de termo precoce (14,2%). Discussão: Na nossa amostra, a prevalência de parto pré-termo tardio e de termo precoce, ainda que ligeiramente inferior, é comparável à publicada em estudos anteriores. Conclusão: Á importante que a comunidade obstétrica nacional adote atitudes no sentido de limitar os partos antes das 39 semanas de gestação. Assim, nestas idades gestacionais os partos devem possuir uma indicação médica válida.

    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. The less porous varieties of the Ançã limestones (< 20 % porosity) were mainly used for masonry, paving and production of lime. The royal Palace of Buçaco is a remarkable masonry building constructed at the end of the XIX century with the less porous varieties of the Ançã limestones

    Background Integrated care is increasingly present in the agenda of policy-makers, health professionals and researchers as a way to improve care services in relation to access, quality, user satisfaction and efficiency. These are overarching objectives of most sectoral reforms. However, health care and social care services and systems are more and more dependent on the performance of each other, imposing the logic of network. Demographic, epidemiologic and cultural changes result in pressure to increase efficiency and efficacy of services and organisations in both sectors and that is why integrated care has become so relevant in the last years. Methods We first used concept maps to organise and systematise information that we had gathered through deep literature review in order to set a framework where to base the subsequent work. Then, we interviewed informants at several levels of the health and social care systems and we built a list of major recent reforms addressing integrated care in Portugal. In a third step, we conducted two independent focus groups where those reforms were discussed and evaluated within the context of the concepts and frameworks identified from the literature. Results were confronted and reconciled, giving place to a list of requisites and guidelines that oriented further search for documentation on those reforms. Results Several important health reforms are in course in primary and hospital care in Portugal, while a so-called third level of care has been introduced with the launch of the National Network of Long-Term Integrated Care (RNCCI – Rede Nacional de Cuidados Continuados Integrados). The social care sector has itself been a subject of alternative models springing from opposite political orientations. All these changes are having repercussions on the way the systems work with each other as they are leading to ongoing and ill-evaluated reformulations on the way they are governed, financed, structured and operated.

    A key issue in fire management is the ability to explore and try to predict where and when fires are more likely to occur. This information can be useful to understand the triggering factors of ignitions and for planning strategies to reduce forest fires, to manage the sources of ignition and to identify areas and frame period at risk. Therefore, producing maps displaying forest fires location and their occurrence in time can be of great help for accurately forecasting these hazardous events. In a fire prone country as Portugal, where thousands of events occurs each year, it is involved to drive information about fires over densities and recurrences just by looking at the original arrangement of the mapped ignition points or burnt areas. In this respect, statistical methods originally developed for spatio-temporal stochastic point processes can be employed to find a structure within these large datasets. In the present study, the authors propose an approach to analyze and visualize the evolution in space and in time of forest fires occurred in Portugal during a long frame period (1990 - 2013). Data came from the Portuguese mapped burnt areas official geodatabase (by the Institute for the Conservation of Nature and Forests), which is the result of interpreted satellite measurements. The following statistical analyses were performed: the geographically-weighted summary statistics, to analyze the local variability of the average burned area; the space-time Kernel density, to elaborate smoothed density surfaces representing over densities of fires classed by size and on North vs South region. Finally, we emploied the volume rendering thecnique to visualize the spatio-temporal evolution of these events into a unique map: this representation allows visually inspecting areas and time-step more affected from a high aggregation of forest fires. It results that during the whole investigated period over densities are mainly located in the northern regions, while in the

    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.

    Concerns about traces of numerous toxic substances and authenticity have prompted consumer demand for honey that is certified as organic, based on strict ecological, natural principles and traceability. The present study aims to characterize organic honey samples (n = 73) from Northeast Portugal, with respect to floral nectar origin, physicochemical parameters and microbial safety. The phenols and flavonoids contents, often referred to as responsible for honey's bioactive properties, were also assessed. All organic honey samples were classified as monofloral lavender (Lavandula sp.), exceeded in quality the international physicochemical standards and showed low microbiological counts (yeast, moulds and aerobic mesophiles), with negative results in respect to fecal coliforms, Salmonella and sulphite-reducing Clostridium spp. Correlation of the palynological, physicochemical and microbiological results is necessary to check the authenticity, quality and sanitation of honey. Although not required by international legislation, results of those assessments provide a complete outlook and elucidation of the organic honey's properties, which could promote its valorisation.

    Primary healthcare in Portugal is undergoing a major reform, of which family health units (FHU) are one of the more visible results. This study aimed to evaluate the FHU implementation process from 2006 onwards. Methods from a previous study of primary healthcare implementation in Brazil were used. Dimensions studied included comprehensiveness of care, organization of care, and the political-institutional perspective. The main improvements identified included better availability of care, team work, technical quality of care, innovative management practices, sustainability of the model, working conditions and infrastructure improvements. Main challenges remaining include integration with hospital care, political and institutional gray areas, need for better information systems, integration within health centers and workflow organization. These data may be useful for management decision-makers when making adjustments and corrections in the reform process.

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

    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

    Equity of access to health services is a major concern as it is an important precondition for positive health outcomes. However, inequities in use of health services among immigrant populations persist. Despite the increasing research in the field, patterns of healthcare seeking among immigrant populations and its associated factors are not fully understood. This study aimed to investigate healthcare-seeking patterns among immigrants in Portugal and identify factors associated with utilisation of health services. A cross-sectional study was conducted between October 2008 and May 2009 with a sample of 1,375 immigrants residing in the Lisbon region. Data were collected through a structured questionnaire applied by trained interviewers. Two stepwise logistic regressions were conducted to identify which factors were associated with utilisation of the National Health Service (NHS) and with healthcare seeking for the first time in Portugal at the Primary Health Care service, estimated by calculating odds ratios and 95% confidence intervals. Among participants, around 77% reported having used the NHS; 50% sought health-care for the first time at the Primary Health Care service and 33% at the emergency room. Lower odds of having used the NHS were associated with being male, Brazilian or eastern European compared with being African, and undocumented. Lower odds of having sought health-care for the first time at the Primary Health Care service were associated with being male and undocumented. These results suggest that further efforts are needed to tackle inequalities in access to care and promote the utilisation of health services, particularly among the more vulnerable immigrant groups. Increasing appropriate utilisation of health services, including the primary and preventive care services, may lead to better health outcomes. Immigrants' involvement and participation should be incorporated into the development of health strategies to improve access and utilisation of

    Vitorino, J.; Monteiro, M.

    In April 2001 the Portuguese Navy conducted a naval exercise (Swordfish 2001) in the area off Cape Sao Vicente, in the southwest tip of Portugal. The operational environ- mental assessment (OEA) component of this exercise, conducted by Instituto Hidro- grafico, intended to provide forecasts of the oceanographic conditions to the naval forces. A program of observations, which included CTD casts to maximum depth of 2500m and AXBTs casts to maximum depth 1000m, was conducted in the area be- tween 35zN and 39zN and from 7zW to 12.5zW. Forecasts of the oceanographic con- ditions were produced using the Harvard Ocean Prediction System (HOPS) with as- similation of the hydrographic data. The period covered by the exercise was character- ized by predominant southerly winds, forcing upwelling conditions along the western Portuguese coast. These conditions promote the development of a large cold upwelling filament that extended a few hundreds of kilometers southwards Cape Sao Vicente. In this communication we present several results obtained for the period between 18 to 28 April 2001, marked by an event of two days of inversion of the upwelling favor- able. The numerical runs were obtained using two nested domains, one covering the global area of observations and the second one covering the shelf and slope area off Cape Sao Vicente. Double-sigma coordinates were used in both domains, with a total of 20 sigma levels. The surface forcing used the wind fields generated by ALADIN- Portugal, a limited area model (12.7-km grid resolution) nested on a global model (ARPEGE).

    Population ageing has paved the way for important and lasting multigenerational bonds, particularly between grandparents and grandchildren. Proximity is a powerful enhancer of relations, and co-residence, by involving continual proximity and long-term commitment, is particularly facilitative of significant linkages between generations. Although co-residence has generally been decreasing in Western societies, in the last decades of the millennium, a trend reversal was identified in the proportion of multigenerational households in the USA. Using data drawn from the European Community Household Panel, 1994-2001, some descriptive insights are provided that were considered to be missing in regard to the socio-demographic composition of extended households with grandparents in Portugal. Additionally, this study finds a rising trend in the proportion of multigenerational households, specifically those that include both grandparents and grandchildren. Portugal is possibly the European country that has the highest probability of exhibiting this pattern of evolution, because of the combination of its being a welfare state with limited resources, its historical reliance on family solidarity and its high level of participation of women in the labor market. Co-residence is a type of intergenerational transfer that can benefit any of the generations involved, but the direction of its net flow is still open to debate. A breakdown is made of its trend into age, period and cohort effects, in order to contribute to the discussion of the relative importance of the different generations in the shared living arrangement. Our findings suggest a mixture of interests, as well as a predominant influence of contemporary circumstances in the observed trend. These contemporary circumstances may be persistent or transient, but co-residence with grandparents is certainly an enduring mechanism, which households use in order to meet their needs.

    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.

    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.

  4. Managerialism and professional strategies: a case from nurses in Portugal.

    PubMed

    Carvalho, Teresa

    There have been profound changes in the Portuguese national health system (NHS), instigated under the influence of managerialism and the new public management (NPM) "philosophy". These changes have been in line with what has happened in other developed countries. At the beginning of the new century, important reforms that emphasised the efficient use of scarce resources were implemented. The objective of this study is to understand how nurses are adapting to a more managerial environment, one in which economic rationalism and market-driven initiatives are the key principles behind the health reforms. A qualitative study was developed, based on semi-structured interviews with 83 nurses with managerial duties in ten hospitals in Portugal. All interviews were tape-recorded and each interviewee's discourses were subjected to content analysis. Data analysis led to the conclusion that under the new logic of the market and managerialism, these professionals have tried to (re)define their professionalisation route by emphasising the importance of care but also by trying to incorporate management as their dominant role in the social division of work. In reconfiguring their notion of professionalism, nurses were incorporating new practices in their day-to-day activities. This empirical study confirms that professionalism can also be conceptualised as a technology of self-control being able to discipline professionals at the micro level. This research is an empirical study based on the effects of managerialism on nurses with managerial duties in Portugal. This study contributes to a better understanding of the complex process of the professionalisation of nurses in a context of institutional change.

    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.

    Although critically ill children may be at risk from developing deep venous thrombosis (DVT), data on its incidence and effectiveness of thromboprophylaxis are lacking. To describe the use of thromboprophylaxis in critically ill children in Spain and Portugal, and to compare the results with international data. Secondary analysis of the multinational study PROTRACT, carried out in 59 PICUs from 7 developed countries (4 from Portugal and 6 in Spain). Data were collected from patients less than 18 years old, who did not receive therapeutic thromboprophylaxis. A total of 308 patients in Spanish and Portuguese (Iberian) PICUS were compared with 2176 admitted to international PICUs. Risk factors such as femoral vein (P=.01), jugular vein central catheter (P<.001), cancer (P=.03), and sepsis (P<.001), were more frequent in Iberian PICUs. The percentage of patients with pharmacological thromboprophylaxis was similar in both groups (15.3% vs. 12.0%). Low molecular weight heparin was used more frequently in Iberian patients (P<.001). In treated children, prior history of thrombosis (P=.02), femoral vein catheter (P<.001), cancer (P=.02) and cranial trauma or craniectomy (P=.006), were more frequent in Iberian PICUs. Mechanical thromboprophylaxis was used in only 6.8% of candidates in Iberian PICUs, compared with 23.8% in the international PICUs (P<.001). Despite the presence of risk factors for DVT in many patients, thromboprophylaxis is rarely prescribed, with low molecular weight heparin being the most used drug. Passive thromboprophylaxis use is anecdotal. There should be a consensus on guidelines of thromboprophylaxis in critically ill children. Copyright © 2014 Asociación Española de Pediatría.

    Canine leishmaniasis (CanL) caused by Leishmania infantum is a serious zoonotic public health and veterinary problem in the Mediterranean basin. Leishmania infection in domestic cats (Felis catus domesticus) has been reported in several countries where this zoonosis is endemic, such as Portugal, Spain, Italy, France, Greece, Israel, Palestine and Brazil. The aim of this study was to contribute to the knowledge of the role played by cats in Leishmania epidemiology, in an endemic focus of zoonotic leishmaniasis, the Lisbon metropolitan area, Portugal. L. infantum DNA was detected in peripheral blood of 28 out of 138 cats (20.3%). The result of PCR in blood of cats was not closely associated with the level of specific circulating antibodies in their sera. Positive serology was observed only in one cat out of 76. In the same geographic region and time period the indirect immunofluorescent test revealed 20.4% (31/152) of dogs with antibodies and PCR detected Leismania DNA on 34.9% (53/152) animals. Despite the fact that specific antibodies have been validated for diagnosis of CanL, their detection does not seem to be sensitive enough to predict Leishmania infection in cats. On the other hand, the presence of parasite DNA in cat's peripheral blood during the transmission season and out of the season suggests that these animals living in endemic areas are frequently exposed or infected with the parasite. Although dogs have been universally regarded as the major domestic/peridomestic reservoir hosts, the present data allow us to hypothesize that cats can act as an alternative reservoir host of L. infantum, rather than an accidental host. However, in order to evaluate the existence of a transmission cycle with cats sustaining and spreading zoonotic leishmaniasis is necessary to prove that these animals can transmit the parasite to the vector in nature.

    TSUNAMI FLOODING ALONG TAGUS ESTUARY (PORTUGAL), THE 1531 EVENT The city of Lisbon one of the main towns in Europe between the XVI and XVIII centuries was severely damaged by two strong earthquakes: 1531-01-26 and 1755-11-01 and the companion tsunamis. In this study we present a re-evaluation of the data available for this event. The 26 January 1531 earthquake occurred between 4 and 5 am and was felt mainly in Lisbon and surroundings dwellings along the Tagus river estuary. The shock heavily destroyed Lisbon downtown causing approximately 1000 casualties Two foreshocks preceded the event: on the 2nd and the 7th January 1531, respectively. The maximum MSK intensity is IX, making it one of the most disastrous earthquakes in the recent history of Portugal. The historical descriptions clearly describe the observation of high waves and the ships touching the riverbed. Although, the difference between tsunamis and storms is sometimes unclear in some historical documents, in this case, the occurrence of the of the earthquake definitively states clearly excludes the hypothesis of a storm. Moreover, the king's chronicle clearly states the observation of high waves and the lack of wind. Other reports consistent with the occurrence of a tsunami are the observation of strong fluxes and refluxes in the river the division of islands into smaller ones and the observation of the riverbed. In this study we present a re-appraisal of the historical information available, a new isoseismal map and the relocation of the epicentre. Finally, we present a tsunami simulation and propagation along a section of 70 km along Tagus estuary compatible with the earthquake data and the historical accounts.

  9. Prevalence of asthma in Portugal - The Portuguese National Asthma Survey

    2012-01-01

    Background Asthma is a frequent chronic respiratory disease in both children and adults. However, few data on asthma prevalence are available in Portugal. The Portuguese National Asthma Survey is the first nationwide study that uses standardized methods. We aimed to estimate the prevalence of current asthma in the Portuguese population and to assess the association between ‘Current asthma’ and comorbidities such as upper airways disease. Methods A cross-sectional, population-based, telephone interview survey including all municipalities of Portugal was undertaken. Participants were randomly selected to answer a questionnaire based on the Portuguese version of the GA2LEN survey. ‘Current asthma’ was defined as self-reported lifetime asthma and at least one of 3 symptoms in the last 12 months: wheezing, waking with breathlessness or having an asthma attack. Results Data were obtained for 6 003 respondents, with mean age of 38.9 (95%CI 38.2-39.6) years and 57.3% females. In the Portuguese population, the prevalence of ‘Current asthma’ was 6.8% (95%CI 6.0-7.7) and of ‘Lifetime asthma’ was 10.5% (95%CI 9.5-11.6) Using GA2LEN definition for asthma, our prevalence estimate was 7.8% (95%CI 7.0-8.8). Rhinitis had a strong association with asthma (Adjusted OR 3.87, 95%CI 2.90-5.18) and the association between upper airway diseases and asthma was stronger in patients with both rhinitis and sinusitis (Adjusted OR 13.93, 95%CI 6.60-29.44). Conclusions Current asthma affects 695 000 Portuguese, with a prevalence of 6.8%. People who reported both rhinitis and sinusitis had the highest risk of having asthma. PMID:22931550

    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.

    Several studies have shown that wildfires in Portugal presenthigh temporal as well as high spatial variability (Pereira et al., 2005, 2011). The identification and characterization of spatio-temporal clusters contributes to a comprehensivecharacterization of the fire regime and to improve the efficiency of fire prevention and combat activities. The main goalsin this studyare: (i) to detect the spatio-temporal clusters of burned area; and, (ii) to characterize these clusters along with the role of human and environmental factors. The data were supplied by the National Forest Authority(AFN, 2011) and comprises: (a)the Portuguese Rural Fire Database, PRFD, (Pereira et al., 2011) for the 1980-2007period; and, (b) the national mapping burned areas between 1990 and 2009. In this work, in order to complement the more common cluster analysis algorithms, an alternative approach based onscan statistics and on the permutation modelwas used. This statistical methodallows the detection of local excess events and to test if such an excess can reasonably have occurred by chance.Results obtained for different simulations performed for different spatial and temporal windows are presented, compared and interpreted.The influence of several fire factors such as (climate, vegetation type, etc.) is also assessed.

    To analyse social actors' frameworks of meaning regarding the definition of health-care quality in Colombia and Brazil. This was a descriptive, interpretative, qualitative study which used focus-groups and individual indepth interviews in two municipalities in Colombia and Brazil. The following social actors were theoretical sampled to represent the variety of views: users and leaders, health-care personnel and policy-makers. Content was analysed with mixed generation of categories and segmentation by country, actors and themes. The frameworks of meaning regarding health-care quality for users and health personnel in both countries revealed coincidences concerning three main topics: structural suitability, technical level and humanisation of care. However, they had differentiated meanings; users from both countries highlighted structural and organisational aspects, together with technical aspects such as resolution level and quality of care. Colombian and Brazilian health-care personnel shared some views but whilst the former highlighted non-bureaucratic and consultation time, the latter singled out the availability of specialised personnel, materials and equipment. Policy-makers' framework of meanings emerge from the legal framework. Features provided by the social actors' frameworks of meaning indicated the need to take them all into consideration as they all pointed out different system weaknesses. They also showed that users valued technical quality more than is generally considered.

  19. Interactive Theater Experience with 3D Live Captured Actors and Spatial Sound

    NASA Astrophysics Data System (ADS)

    Cheok, Adrian David

    This chapter introduces a new reality interactive theater that combines the 3D Live human capturing system, spatial sound, augmented reality, human-oriented interaction, and ambient intelligence technologies. Actors/Dancers at different places remotely are captured by the 3D Live system and transmitted to the theater place in real time and rendered in 3D form and real size, thus they can play/dance with the local actors/dancers and virtual characters at the same place in real time. Audience interaction is allowed and handled by an Ambient Intelligence (AI) agent to generate new actions for virtual characters and send meaningful interactions to real actors. The spatial sound system provides the real 3D sound and at the same time generates special sound effects such as controlling the sound direction that only allows people in a certain direction to heard it. All these features combined together bring a totally new theater experience to both actors/dancers and audiences, and extend the grammar of the traditional theater.

    PubMed

    Granero, Lluís; Villalbí, Joan Ramón; Gallego, Raquel

    2004-01-01

    For a comprehensive approach to policies on smoking, the map of actors related to tobacco and their political ties needs to be identified. The present article constitutes the first attempt at this task in Spain. Analysis of the press, industry publications, and interviews with key people. Active actors favoring smoking in Spain were identified and classified according to their characteristics, the sphere in which they act, and their preferred territorial arena. We identified tobacco companies (Altadis and Philip Morris dominate the market), tobacco trade organizations (tobacconists), front-line organizations created by the tobacco industry (The Smokers for Tolerance Club), organizations of tobacco growers, and processing companies. Distribution to retailers is dominated by Logista, owned by Altadis. Other sectors to take into account are vending companies and those manufacturing related products (cigarette paper, matches or lighters). The contacts of these actors with the public administration are reviewed, notable among which are the role of the Commissioner for the Tobacco Market, the Ministry of Agriculture, the Ministry of Finance and the Ministry of the Economy. Ties were also found with employers' organizations, some political parties, and unions, as well as with other sectors with social influence such as the media and advertising sectors. The map of actors favoring smoking in Spain is complex and goes beyond the confines of the tobacco industry. Understanding this web is crucial to promoting comprehensive prevention policies.

  1. Shaping the midwifery profession in Nepal - Uncovering actors' connections using a Complex Adaptive Systems framework.

    2016-12-01

    To explore how actors connect in a system aiming at promoting the establishment of a midwifery profession in Nepal. A qualitative explorative study based on the framework of Complex Adaptive Systems. Semi-structured interviews were conducted with 17 key people representing eight different organisations (actors) promoting the development of the midwifery profession. The actors' connections can be described with a complex set of facilitators for and barriers to promoting the establishment of a midwifery profession. The identified facilitators for this establishment in Nepal are (1) a common goal and (2) a desire to collaborate, whilst the barriers are (1) different political interests and priorities, (2) competing interests of the nursing profession and societal views, (3) divergent academic opinions on a midwifery profession, and (4) insufficient communication. The results also showed that Nepalese society cannot distinguish between nursing and midwifery and that the public support for a midwifery profession was hence minimal. The move of midwifery from an occupation to a profession in Nepal is an on-going, challenging process. The study indicates the importance of understanding the motivations of, and barriers perceived by, actors that can promote or obstruct the establishment of the midwifery profession. It also points to the importance of informing the wider public about the role and responsibility of an autonomous midwifery profession. Copyright © 2016 Elsevier B.V. All rights reserved.

  17. Extended mind and after: socially extended mind and actor-network.

    PubMed

    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.

  19. Ex-couples' unwanted pursuit behavior: an actor-partner interdependence model approach.

    PubMed

    De Smet, Olivia; Loeys, Tom; Buysse, Ann

    2013-04-01

    Unwanted pursuit behavior (UPB) refers to a wide range of repeated, unwanted, and privacy-violating intrusions that are inflicted to pursue an intimate or romantic relationship. These behaviors most often occur when partners end their romantic entanglements. Despite the fact that UPB is grounded in relationships, psychological explanations for post-breakup UPB perpetration have been restricted to actor effects assessed in samples of separated individuals. For that reason, the present study aimed to identify feasible partner effects that additionally explain UPB perpetration using a Flemish sample of 46 heterosexual divorced couples, beginning with the notion of interdependence. Using actor-partner interdependence models, we explored actor, partner, and gender main and interaction effects of anxious attachment, satisfaction, alternatives, investments, and conflict in the previous marriage on the perpetration of post-divorce UPBs. The significant Partner × Gender interactions of anxious attachment and satisfaction, Actor × Partner interactions of anxious attachment and quality of alternatives, and the marginally significant partner effect of relational conflict underline the important role of the dyad in studying UPB perpetration. These findings shed new light on the nature of UPB perpetration that go beyond the individual and support the use of a systemic approach in clinical practices.

    Cerebrovascular disease has long been the leading cause of death in Portugal. Despite improvements in the treatment of hypertension and the resulting decrease in associated mortality, the progressive aging of the population and increased prevalence of atrial fibrillation have prevented the incidence of stroke from falling as much as desired. The authors review the evidence on the situation in Portugal and propose an intervention plan.
