Black carbon trends in southwestern Iberia in the context of the financial and economic crisis. The role of bioenergy.

Since black carbon concentrations are useful to reveal changes in anthropogenic activities, measurements taken from 2007 to 2015 in a Portuguese city are used to assess to which extent the ambient air was impacted by the economic crisis. The average black carbon concentrations are representative of an urban area of small size (1.3 ± 1.3 μg m−3). The highest concentrations are observed in the heating season, being biomass combustion one of the causes for the high values. The daily cycle of black carbon concentrations presents both morning and evening peaks, mainly due to road traffic and, in the heating season, to domestic heating as well. The yearly averaged black carbon mass concentrations decreased 33 % from 2007 to 2015, possibly due to a combination of the economic recession and environmental legislation. The reduction in road traffic led to a decrease in the daily morning peak from 2007 to 2015. This reduction was not followed by a decrease in the evening peak, explained by an increase in biomass burning. Biomass is the cheapest heating fuel in Portugal, and its consumption increased in the aftermath of the economic crisis. The use of bioenergy is an alternative to fossil fuels and presents many advantages. However, energy policies should discourage inefficient biomass burning and promote better ways of exploiting the available energy resources and emission air pollution mitigation strategies.

The culture of background investigations (Portugal, 1570-1773)

This article seeks to justify why it is possible to speak about a culture of background investigations in Portugal, or even in the Iberian Peninsula, especially in the 17th-18th centuries. It will emphasize three points: the huge number of people who made qualifications in Portugal and in the overseas Empire; how it created specialized knowledge and the need for specialized officers to deal with it; to demonstrate how the culture of qualification conditioned behaviors in different social groups.

Allergological evaluation of a dog population in a veterinary immuno-allergology consultation: What correlates in a canine model

Introduction: Allergic dermatitis (AD) is the most common canine pruritic condition in veterinary dermatology. Allergic dermatitis to flea bites presents the highest prevalence, followed by atopic dermatitis and food AD. This study aimed to identify possible correlation between data from clinical signs, intradermal tests (IDT) and specific IgE levels, which are used in dog AD assessment. Methods: Fifty five dogs from the Veterinary Hospital of the University of Évora (Portugal) and Rof Codina University Hospital (Lugo, Spain) outpatient consultations were studied by means of clinical inquiry, IDT and specific IgE determination. Thirty five of the patients belonged to predisposed breeds, 30 were females and 25 males. Forty one (74%) were indoor. Results: In 82% of cases first clinical signs appeared before the age of 3 years and 24% even before 1 year old. In 70% of the individuals clinical signs included itching, which was generalized in 66%, with 78% of paw licking and chewing. Clinical profile showed seasonal worsening in 64% of cases. From the 69.1% of dogs already presenting with dermatitis, 50% also presented external otitis and 28.9% self-inflicted alopecia. "Intense itching" was found in 10.5%, "medium itching" in 81.6% and “mild itching” in 5.26% of the patients. Prevalence of positive IDT was 37.3 % to Lep d, 29.41% to Der f, 27.5% to Der p, 25.5% to Dac g and 21.6% to Malassezia sp. From the 37 dogs submitted to food IDT, 40.5% revealed positive to beef, 27% to chicken, 27% to porc and 5.4% to lamb. Specific IgE > 150 EAU was found in 84% of dogs to indoor allergen sources and in 68% to pollens. A negative correlation was found between an outdoor life and the intensity (p = 0.033) and precocity (p = 0.026) of clinical signs. Sensitization to pollens was found positively correlated with the seasonality of clinical signs (p = 0.001) and the positivity for Dac g (p = 0.007). The prevalence of chronic otitis correlated positively with alopecia and reactivity to Lep d (p = 0.008), Plantago lanceolata (p = 0.026) and Platanus acerifolia (p = 0.017). There was no correlation between the results of ITD and specific IgE. Conclusion: We can conclude that correlation between different clinical signs and positive testing for some allergenic sources may occur, as well as between sensitization to pollens and the beginning, the intensity and the seasonality of dog patient clinical signs.

First detection of Bursaphelenchus luxuriosae associated with Pinus pinaster in Portugal

During a field survey carried out on symptomatic maritime pine trees (Pinus pinaster) in Góis, central Portugal, Bursaphelenchus luxuriosae was isolated for the first time in Portugal, and in Europe. Identification of the nematodes was based on morphological characters and molecular analyses for this species. The general morphology of both females and males is in agreement with the original description for B. luxuriosae, namely the typical morphology of the male spicules and the conspicuous morphology of female tail. Species identification was confirmed through sequencing of the ITS rDNA region and the fragment spanning the D2/D3 domain of the 28S rDNA gene. This species belongs to the xylophilus-group and is the third species in this group known in Portugal. The nematodes were retrieved in small numbers (<100 nematodes/100 g dry wood), and no insect vector association could be established.

Rock paintings and microorganisms: a new insight on Escoural cave

European cave art is of tremendous importance to understand the cultural traditions of the Upper Palaeolithic (35 000 – 10 000 BP) populations. Indeed, Prehistoric communities performed numerous cave paintings all over Western Europe. Understanding these artworks should provide a better knowledge of these early cultural aspects. Although numerous studies have been carried out to analyse the materials used by those communities, nothing has been done on the techniques’ palette of Escoural Cave’s representations. The present work aims at providing the very first data about the techniques and materials used by the Prehistoric to perform the cave paintings of Escoural (Alentejo, Portugal), and the microorganisms possibly endangering this unique parietal art. In situ observations coupled with an extensive micro-sampling and micro-destructive analyses allowed to characterize the coloured material and the way they were applied on the walls of the cave. Both red and black pigments present major composition’s disparities among the different paintings and drawings, supporting a more complex occupations’ chronology than what was earlier thought. The Palaeolithic paintings have suffered deterioration from environmental conditions and include chemical, mechanical and aesthetic alterations, possibly as a result of fungal activity. The standard techniques for biological assessments used in these contexts provided important insights on the diversity of the microbial population, though they have accuracy limitations. To understand the extent and viability of the existing microbiota, DNA quantification and biomarkers analyses, such as desidrogenase activity were performed and correlated with ergosterol amounts; RESUMO: A Arte Rupestre Europeia é de grande importância para compreender as tradições culturais da população do Paleolítico Superior (35 000 - 10 000 BP). De fato, as comunidades Pré-históricas realizaram inúmeras pinturas rupestres em toda a Europa Ocidental, sendo crucial compreender estas obras de forma a proporcionar um melhor conhecimento destes ancestrais aspectos culturais. Embora vários estudos tenham sido realizados para analisar os materiais utilizados por estas comunidades, nada foi efetuado sobre a técnica de execução das representações presentes na Gruta do Escoural. O presente trabalho visa fornecer os primeiros dados sobre as técnicas e materiais utilizados na Pré-História para executar as pinturas rupestres de Escoural (Alentejo, Portugal) bem como caracterização dos microorganismos possivelmente associados aos danos deste bem único. Observações in situ, juntamente com uma extensa micro-amostragem e análises micro-destrutivas permitiu caracterizar os pigmentos utilizados e a forma como eles foram aplicados nas paredes da caverna. Tanto os pigmentos vermelhos como os pretos apresentam composição distinta nas diversas pinturas e desenhos aí representados, apoiando a presença de diferentes ocupações contrariamente ao que se pensava até então. As pinturas Paleolíticas têm sofrido deterioração, devido às condições ambientais, nomeadamente alterações químicas, mecânicas e, possivelmente como resultado da atividade fúngica. As técnicas usualmente utilizadas para a avaliação de contaminação biológica fornecem informação importante sobre a diversidade da população microbiana, embora apresentem algumas limitações. Para entender a extensão e a viabilidade da microbiota existente, a quantificação de DNA e análise de biomarcadores como actividade de desidrogenases foram realizadas e correlacionadas com o conteúdo em ergosterol.

Pine wilt disease: a worldwide threat to forest ecosystems

The pinewood nematode (PWN), Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD), is a serious pest and pathogen of forest tree species, in particular among the genus Pinus. It was first reported from Japan in the beginning of the XXth century, where it became the major ecological catastrophe of pine forests, with losses reaching over 2 million m3/ year in the 1980s. It has since then spread to other Asian countries such as China, Taiwan and Korea, causing serious losses and economic damage. In 1999, the PWN was first detected in the European Union (EU), in Portugal, and immmediately prompted several government (national and EU) actions to assess the extent of the nematode’s presence, and to contain B. xylophilus and its insect vector (Monochamus galloprovincialis) to an area with a 30km radius in the Setúbal Peninsula, 20 km south of Lisbon. International wood trade, with its political as well as economic ramifications, has been seriously jeopardized. The origin of the population of PWN found in Portugal remains elusive. Several hypotheses may be considered regarding pathway analysis, basically from two general origins: North America or the Far East (Japan or China). World trade of wood products such as timber, wooden crates, palettes, etc… play an important role in the potential dissemination of the pinewood nematode. In fact, human activities involving the movement of wood products may be considered the single most important factor in spreading of the PWN. Despite the dedicated and concerted actions of government agencies, this disease continues to spread. Very recently (2006), in Portugal, forestry and phytosanitary authorities (DGRF and DGPC) have announced a new strategy for the control and ultimately the erradication of the nematode, under the coordination of the national program for the control of the pinewood nematode (PROLUNP). Research regarding the bioecology of the nematode and insect as well as new detection methods, e.g., involving real-time PCR, has progressed since 1999. International agreements (GATT, WTO) and sharing of scientific information is of paramount importance to effectively control the nematode and its vector, and thus protect our forest ecosystems and forest economy.

Pine Wilt Disease: A Threat to Pine Forests in Turkey?

The pinewood nematode, is the causal agent of pine wilt disease, a serious threat to native pine forest in eastern Asia (Japan, Korea, China and Taiwan) and some parts of North America (USA, Canada and Mexico). In 1999, this nematode was found and identified for the first time in Portugal and in Europe. The detection of this quarantine pest in Portugal has indicated the need to know more about the distribution of Bursaphelenchus spp. in coniferous trees in Europe in order to describe the geographic range of the species and to act quickly in case of the nematode’s unwanted introduction into other European regions. Pine forest has a wide distribution in Turkey that increases the number of susceptible host trees for pinewood nematode. Because of these resaons, some regions of Turkey were surveyed for the presence of the nematode. Three different species of Bursaphelenchus were found. However, B. xylophilus was not detected. The detection of B. mucronatus, very similar to B. xylophilus biologically and morphologically, is very important. The presence of this species indicates that B. xylophilus could spread easly in conifer forests of Turkey. A study was conducted to determine the pathogenicity of B. mucronatus and 80% of seedlings of P. sylvestris were wilted. Biological characteristics of M. galloprovincialis were compared with M. carolinensis, Nort American vector, and some of them were found to be similar.

A violência contra idosos e suas representações sociais

O trabalho de investigação documentado nesta dissertação insere-se no estudo das representações sociais da violência contra idosos. Para tanto, recorreu-se à Teoria das Representações Sociais de Serge Moscovici com o objetivo de conhecer as representações acerca da violência contra o idoso, identificando as perspectivas distintas de três grupos participantes de dois países, Portugal e EUA Realizou-se um estudo qualitativo do tipo descritivo, explorando as representações sociais acerca da violência contra idosos mas, também, de carácter comparativo já que oferece a perspectivas de três grupos distintos. Buscou-se saber dos pensamentos acerca da violência sobre o idoso nas perspectivas do próprio idoso, de famílias de idosos e profissionais da área de saúde que prestam assistência à pessoas idosas. O estudo propiciou uma discussão do fenômeno como comportamento social refletindo sobre questões epidemiológicas e psico-sociais que o caracterizam como um dos mais graves na esfera da saúde pública. As questões sócio-demográficas foram processadas através do programa estatístico SPSS e, a produção discursiva das 240 entrevistas, analisada através dos programas estatísticos ALCESTE e, IRAMUTEQ.Apesar das diferenças socio-culturais, os participantes construíram representações sociais da violência contra idosos similares, associadas à identidade social do idoso que os coloca como vítima iminente de violência. As divergências encontram-se nas expectativas de intervenção e prevenção do fenômeno; Violence against the elderly and its social representation Abstract: The research documented in this dissertation is part of a study about elderly violence, considered to be one of the most serious issues in the sphere of public health and examined here through the lens of the Theory of Social Representations. The main objective is to know the perspectives of the elderly, families and health professionals from two countries: Portugal and United States of America, on the subject of elderly violence. Using a qualitative design, this study applied both, descriptive and comparative methods interviewing 240 individuals. The demographic data were analyzed through SPSS and the lexical analysis which were performed by two software programs, ALCESTE and IRAMUTEQ. The social representations of elderly violence had similarities associating violence to the social identity of the elderly as an eventual victim despite cultural differences. Variations are identified in the expectations regarding strategies of intervention and prevention of the phenomena.

A ideia de Europa na imprensa desportiva portuguesa (1893-1945)

Pensar a Europa e Portugal, a partir da imprensa desportiva portuguesa, é o principal objectivo deste trabalho, que deve ser visto como uma espécie de "viagem" por um tempo conturbado (1893-1945), com os principais jornais desportivos a servirem de guia. Esta longa peregrinação de 52 anos — iniciada quando surge o primeiro jornal desportivo em Portugal e encerrada no ano em que termina a Segunda Guerra Mundial (altura em que este género de imprensa se consolida) — permitiu recuperar, simultaneamente, do baú do esquecimento, reflexões sobre a Europa e Portugal, e um pedaço da esquecida história da imprensa desportiva. /***Abstract - The main goal of this work is to think Europe and Portugal starting from the discourses produced in the portuguese spod press on the subject. This research must be seen as a “journey" through a troubled time (1893-1945), with the sport newspapers as guides. It's a long way of 52 years that started when the first portuguese sport newspaper born and finished at the end of the Second World War (period when Chis kind of press was already established) permitted, at the same time, a recovery, from the chests of forgetfulness, of reflections about Europe and Portugal and a piece of forgotten sport press history.

Caracterização da diversidade parasitária em carníveros silvestres e implicações na conservação

Recolher dados para actualizar os conhecimento da diversidade parasitária dos mesocarnívoros mais abundantes nas regiões do sul de Portugal e relacionar a dispersão parasitária, a conservação e a saúde humana constituíram os principais objetivos deste estudo. Raposas (Vulpes vulpes), sacarrabos (Herpestes ichneumon), fuinhas (Martes foina), ginetes (Genetta genetta) e texugos (Meles meles) atropelados foram os carnívoros-hospedeiros em estudo. Um grupo de raposas caçadas foi também considerado parte da amostra. A informação geo-referenciada de todos os animais serviu para executar a análise espacial. Realizaram-se necrópsias meticulosas e procedeu­ se à recolha, identificação e preservação dos parasitas encontrados. Pela primeira vez em Portugal é registada a presença do parasita da gineta Ancytostoma martinezi. A correlação entre os factores humanos e ambientais e, a riqueza de espécies foi determinada estatisticamente. Densidade populacional, disponibilidade de égua, tipo de uso de solo e distância mínima às sedes de concelho não apresentaram uma relação estatisticamente significativa com a infecção parasitária das raposas. Os resultados obtidos relativamente à presença de parasitas zoonóticos nos animais silvestres em estudo fomentam o trabalho multidisciplinar entre a Biologia da Conservação e as ciências médicas. ABSTRACT; The aim of this study was to collect data in order to update the information related to the parasitic diversity of the predominant mesocarnívores in the southern regions of Portugal and to establish relationships between the parasite dispersal, conservation and human health. Road killed foxes (Vulpes vulpes), mongoose (Herpestes ichneumon), stone marten (Martes foina), common genets (Genetta genetta) and euroasian badgers (Meles meles) were the considered carnivore-hosts. A sample of hunted foxes was also regarded.AD the animals had geo-reference information, ultimately used for spatial analysis. Thorough necropsies were performed and macroparasites collected, identified and preserved. For the first time in Portugal Ancylostoma martinezi, a common genets parasite.is recorded. Statistical species richness and correlation between human and environmental factors were determined. Human population density, water drainage, soil use, minimum distance to head council cities and the infection status of foxes proved no significant statistical relation. Results obtained on zoonotic parasites present in wild animals enhance the necessity of multidisciplinary work between Biology conservation and medical sciences.

Condicionantes ecológicas que afectam o Sisão durante o início de um ano agrícola

Este estudo foi realizado durante o Outono de 2001, em três áreas agrícolas do Sul de Portugal e tem como objectivo determinar quais os factores que influenciam a selecção de habitat pelo Sisão no Outono. A amostragem baseou-se na realização de transectos a pé. A identificação das preferências de habitat e o desenvolvimento de modelos preditivos foi realizada recorrendo a modelação linear (GLM) e aditiva (GAM). Os resultados da análise à escala da paisagem indicaram que a espécie prefere restolhos de cereal e pousios. Adicionalmente, foram seleccionadas as áreas com melhores solos e mais próximas das linhas de drenagem. As análises relativas ao microhabitat sugerem que o Sisão utiliza preferencialmente áreas com vegetação herbácea baixa e com elevada disponibilidade de plantas verdes. Os resultados sugerem que a disponibilidade alimentar é ainda limitante durante esta época, pelo que a implementação de medidas agro-ambientais compreendendo a manutenção dos sistemas cerealíferos tradicionais e consequentemente dos restolhos e pousios nas áreas com solos mais produtivos, são as medidas adequadas para promover os habitats da espécie. ABSTRACT; This study was carried out in the autumn of 2001, in three cultivated areas of southem Portugal and aims to determine the factors that influence the habitat selection of the Little Bustard in that period of the year. Foot transects were used to locate Little Bustards. GLM and GAM modelling were performed to identify the species' habitat preferences and to develop explanative occurrence models. The results of the landscape analysis indicate that Little Bustards exhibit a preference for cereal stubbles and fallow lands. Additionally, birds were mostly found in fields with best soils and close to water drainage lines. Microhabitat analysis shows that birds seem to prefer short grassy vegetation, where the availability of green plants is higher. Results suggest that food availability is still limiting for the species at this season. Therefore, the implementation of agri-environmental schemes comprising the maintenance of traditional cereal farming and consequently stubbles and fallow land within areas with more productive soils, are adequate measures to promote suitable foraging habitats for the Little Bustard.

Population’s knowledge about cerebrovascular accident (stroke) - passers of the square giraldo in Evora

Stroke is the leading cause of death in Portugal and the Alentejo region. Objective: Describe the population's knowledge about risk factors, signs and symptoms of stroke. Methodology: Quantitative and cross-sectional study. Convenience sample of 207 pedestrians with ages between 16 and 86 years old (M=38,85; SD = 18.93). Results: The pathology is known, the most frequently mentioned sources of information are television and friends. Hypercholesterolemia, heart disease and smoking are the risk factors more set out. The most well known signs are numbness and weakness in the hemisphere and dysarthria. Conclusion: It is necessary to strengthen the role of health services in education about stroke. Knowledge displays weaknesses in appreciation of advanced age and diabetes. Noteworthy is the recognition of the risk associated with tobacco consumption and persistence on it.

Otter (Lutra lutra) distribution modeling at two resolution scales suited to conservation planning in the Iberian Peninsula

We used the results of the Spanish Otter Survey of 1994–1996, a Geographic Information System and stepwise multiple logistic regression to model otter presence/absence data in the continental Spanish UTM 10 10-km squares. Geographic situation, indicators of human activity such as highways and major urban centers, and environmental variables related with productivity, water availability, altitude, and environmental energy were included in a logistic model that correctly classified about 73% of otter presences and absences. We extrapolated the model to the adjacent territory of Portugal, and increased the model’s spatial resolution by extrapolating it to 1 1-km squares in the whole Iberian Peninsula. The model turned out to be rather flexible, predicting, for instance, the species to be very restricted to the courses of rivers in some areas, and more widespread in others. This allowed us to determine areas where otter populations may be more vulnerable to habitat changes or harmful human interventions. # 2003 Elsevier Ltd. All rights reserved.

De modo a terminar o mestrado em Gestão, especialização em Recursos Humanos, considerou-se pertinente a realização de um estágio em contexto laboral, como forma a melhorar as competências técnicas e comportamentais. O estágio teve dois objectivos: aplicação dos conhecimentos adquiridos na primeira fase do mestrado e pesquisa de uma oportunidade de inserção no mercado de trabalho. O mesmo foi realizado na Caixa Geral Depósitos (CGD), empresa escolhida devido à posição de destaque que assume em Portugal e por se considerar que é uma organização líder e forte em muitos aspectos, nomeadamente em áreas da gestão de recursos humanos. Apesar das múltiplas abordagens que a gestão de recursos humanos tem e devido à especialização existente na CGD nesta área, o estágio foi essencialmente centrado no âmbito da formação. Considera-se que trabalhar nessa área trará bastantes beneficias pessoais uma vez que me dotará de competências fundamentais para enfrentar a realidade empresarial actual, que é fortemente acentuada na gestão do conhecimento. ABSTRACT: ln order to finish the master degree in Management, specializing in Human Resources, a pertinent stage-based learning was considered as a way to improve technical and behavioral skills. This stage had two targets: application of the obtained knowledge during the first stage of the master degree, and search for an opportunity of entering the labor market. This same stage was done at Caixa Geral Depósitos (CGD), a company that was chosen because of its prominent position assumed in Portugal, and is also considered a leading and strong organization in many areas, particularly human resource management. Despite the multiple approaches that human resources management has, and due to the know-how of CGD in this area, the stage was mainly focused in the training. It is considered that work in this area will bring many personal benefits as it will give me fundamental skills to deal with the actual business reality, which is strongly marked in knowledge management.

Social Representations of Violence against the Elderly

The repercussions of violence on the mental, social, and physical well-being of the elderly are some of the most challenging problems in public health today. Using a qualitative design, we conducted a study in Portugal and the United States that applied both descriptive and comparative methods in order to understand the social representations of violence against the elderly. Utilizing the Theory of Social Representations, we explored the perspectives of the elderly, their families, and healthcare professionals on the subject of violence against the elderly. The data on which the findings were based were obtained in two very different cultural contexts, yet the representations of violence against the elderly revealed no significant cross-cultural differences. However, conceptualizations regarding expectations of care and protection for the elderly proved to be distinct. We discussed concerns about the general attitudes of tolerance toward violence, including those of the elderly who self-identified as eventual victims. Violence against the elderly was portrayed as a part of old age and also somehow was justified by it. The results also indicated the need to better prepare healthcare professionals and society in general to deal with the consequences of the problem and not, as we would like to report, to prevent it from happening.
