E-Procurement and Innovation in the Portuguese Municipalities: When Change Is Mandatory

Changing the traditional pattern of public procurement for an electronic paradigm is a radical innovation involving major organizational changes, the breaking up of traditional processes and practices, obsolescence of knowledge and skills. Going beyond the European Commission's recommendations, in 2009 Portugal pioneered in making e-procurement mandatory in the pre-award phase, in a European context of multiple technical standards and lack of interoperability of electronic platforms across the EU countries. Six years later, when the creation of a European e-procurement single market is a EU mission and a major legislative amendment is underway in Portugal, this study looks at the relationship between e-procurement and innovation in the Portuguese municipalities aiming to understand the extent into which the adoption of e-procurement embraced a real organizational change or, on the other hand, if it just represented a mere adaptation of the usual procurement practices. The study draws on data from an electronic survey to all municipalities in mainland Portugal and the analysis is mainly descriptive and exploratory. The paradigm shift in public procurement involves major organizational changes but, overall, the results suggest that most municipalities do not have a clear understanding of the innovative scope (depth and diversity) implied by e-procurement. E-procurement shows advantages over the paper-based model but an unbalanced perception of the innovation dimensions has influenced the implementation of e-procurement and the degree of organizational change.

Percurso profissional. Destaque para a análise da produção de resíduos urbanos no Alentejo Central - portugal e utilização do modelo DEA na definição da meta da recolha seletiva

Neste trabalho de Projeto efetua-se o desenvolvimento do tema da produção de Resíduos Urbanos (RU) no Alentejo Central, utilizando-se o modelo DEA (Data Envelopment Analysis) para a análise das metas da recolha seletiva estabelecidas para 2020. Genericamente, quanto maior é o grau de desenvolvimento económico de um território, maior é a taxa de urbanização e maior é também a quantidade de resíduos urbanos produzidos por habitante. O rendimento e a urbanização são variáveis altamente correlacionadas, quando aumenta o rendimento disponível e os padrões de vida, aumenta também o consumo de bens e serviços de modo correspondente, o que leva ao aumento da quantidade de resíduos gerados. Assim, tendo em conta os impactos locais que os RU abandonados trazem, e com o objetivo de quebrar o elo entre crescimento económico e os impactos ambientais associados à produção de resíduos, são implementadas, nos países com elevados níveis de desenvolvimento, políticas baseadas em modelos integrados de gestão de RU que permitem a recuperação, reciclagem e valorização dos materiais, reservando-se a eliminação (deposição em aterro) para frações não valorizáveis, o que gera empregos e riqueza. Em Portugal vigora o Plano Estratégico para os Resíduos Urbanos (PERSU 2020) que define objetivos e metas nacionais, nomeadamente a meta da recolha seletiva, estabelecendo para 2020 um quantitativo nacional mínimo a recuperar de 47 kg por habitante por ano. Deste modo, importa caracterizar, para o período de 2002 a 2012, como evoluiu a produção de RU em comparação com a evolução do PIB em Portugal. A análise foca-se então na produção de RU na região do Alentejo em particular no Alentejo Central que evidencia um elevado nível per capita em comparação com o resto do país, situando-se mesmo acima das regiões do grande Porto e Lisboa. São apresentadas possíveis razões para o registo destes elevados níveis de produção de RU não se conseguindo, no entanto, avançar com evidências. Como o modelo DEA é utilizado no PERSU 2020 para fundamentar a projeção das metas da recolha seletiva por sistema de gestão de resíduos urbanos, fez-se a sua reprodução, o que permitiu uma análise mais detalhada dos dados e o ensaio de novos resultados considerando, para além do nível de produção de RU, o numero de equipamentos de deposição de recolha seletiva como input do modelo; Abstract: Title of the report: Professional career. Emphasis on the analysis of urban waste production in Alentejo Central - Portugal and the use of the DEA in defining the separate collection target This professional report presents the theme of the Urban Waste (UW) production in Central Alentejo, using the DEA (Data Envelopment Analysis) to analyse the target set for selective collection in 2020. Generally, the higher the degree of economic development of a region, the greater the rate of urbanization and the greater also the amount of municipal waste produced per capita. The variables income and urbanization are highly correlated, if you have an increase in the disposable income and living standards, the consumption of goods and services will increase accordingly, which leads to the increase of the amount of produced waste. Thus, taking into account the local impact that the abandoned UW brings, and in order to break the link between economic growth and the environmental impacts associated with the production of waste, countries with high levels of development implement policies based on integrated UW management models that allow the recovery, recycling and valorisation of materials, restricting the disposal (landfill) to non-recoverable fractions, which creates jobs and wealth. Portugal established a national strategic plan for Urban Waste (PERSU 2020) which defines the goals and national targets, including the selective collection target stating for 2020 a minimum recover of 47 kg per capita per year. Then it is relevant to characterize and compare the evolution of UW production and GDP in Portugal for the period 2002 to 2012. The analysis then focuses on the production of UW in Alentejo, particularly in Central Alentejo region, which shows a high per capita level compared to the rest of the country, placed just above the Greater Porto and Lisbon region. Then we explore several possible reasons for this high level of UW production in this region, but none is successful in producing strong evidence. As the DEA is used in PERSU 2020 to support the projection of the selective collection targets for the municipal waste management systems, in this report we develop the model, which allowed access to the data and a more detailed analyse. Then we introduce and test a new input, the number of separate collection deposition equipment, which gives new results that are compared with the original ones.

Living on the intertidal/subtidal edge: ecology of the stalked barnacle Pollicipes Pollicipes and of the sea urchin Paracentrotus lividus

This thesis contributes to the knowledge of temperate rocky shore ecology, with direct implications in the management and conservation of two important local marine resources that inhabit the very edge of subtidal and intertidal habitats on wave-swept rocky shores: the sessile filter feeding stalked barnacle Pollicipes pollicipes and the mobile keystone herbivore sea urchin Paracentrotus lividus. Research was conducted along gradients of wave exposure on rocky shores of Southern Europe. The abundance of P. lividus was four times higher in SW Portugal than in NW Italy. Most of the variation in urchin abundance occurred at small spatial scales, probably shaped by habitat complexity. In SW Portugal, sea urchin attachment forces while in burrows were measured and related to burrow shape, urchin size and habitat. Burrowing behaviour enhances sea urchin attachment force and might be an adaptive response to hydrodynamic stress. Abundance of P. pollicipes in SW Portugal is highly and positively related to wave exposure at local and regional scales. Predation and recruitment processes seem to be important drivers of these abundance patterns. A distribution model of P. pollicipes abundance in relation to wave exposure was developed for the SW coast of Portugal and might be used for improvement of its management and conservation. Growth of P. pollicipes was studied by applying a novel method using fluorescent calcein for marking and to estimate growth. Growth rate decreased with barnacle size and was highly variable amongst individuals, particularly in smaller barnacles. No effect of shore level on barnacle growth was detected. An assessment of the state of the fishery, conservation and management of the stalked barnacle in different regions of continental Portugal was made, highlighting an overall negative tendency of this state and recommending a change into a co-management system; Resumo: Viver no limite intertidal / subtidal: ecologia do percebe Pollicipes pollicipes e do ouriço-do-mar Paracentrotus lividus Esta tese contribui para o conhecimento da ecologia do litoral rochoso e tem implicações diretas na gestão e conservação de dois recursos marinhos locais que habitam o interface subtidal/intertidal de costas rochosas sujeitas a agitação marinha: o percebe Pollicipes pollicipes, animal séssil e filtrador e o ouriço-do-mar Paracentrotus lividus, animal móvel e herbívoro. Foram realizados vários estudos ao longo de gradientes de hidrodinamismo em costas rochosas do sul da Europa. A abundância de P. lividus foi quatro vezes superior no sudoeste de Portugal relativamente ao noroeste de Itália. Grande parte da variação na abundância de P. lividus ocorreu a pequenas escalas espaciais, provavelmente influenciada pela complexidade do habitat. A força com que o ouriço-do-mar se fixa ao substrato foi medida no terreno no sudoeste de Portugal, tendo esta sido relacionada com a forma da depressão que ocupa, o tamanho individual e o habitat. O comportamento escavador desta espécie aumenta a sua força de fixação ao substrato e poderá ser uma resposta adaptativa ao hidrodinamismo.. A abundância de P. pollicipes na costa sudoeste de Portugal, a diferentes escalas espaciais, está relacionada de forma positiva com a agitação marinha, e é influenciada pela predação e pelo recrutamento desta espécie. Foi desenvolvido um modelo de distribuição e abundância de P. pollicipes para esta costa baseado na relação com a agitação marinha, cujos resultados podem ser usados para melhorar a gestão e conservação deste recurso. Um novo método com recurso a calceina fluorescente foi desenvolvido para marcar percebes e estudar o seu crescimento. A taxa de crescimento diminuiu com o tamanho do animal, sendo altamente variável entre indivíduos, sobretudos nos de menores dimensões. O estado da apanha, conservação e gestão do percebe em diferentes regiões de Portugal Continental apresentou uma tendência global negativa, e recomenda-se uma alteração para um sistema de cogestão deste recurso.

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.

Climatic zoning of the Ibero-American viticultural regions.

The Ibero-American Network of Viticulture, a component of the program of agricultural technology of the CYTED (Ibero-American Program of Science and Technology for Development), is developing the project ?Zoning Methodology and Application in Viticultural Regions of Ibero-America?. An objective of the project is the climatic characterization of this large viticultural region with the participation of ten countries: Argentine, Bolivia, Brazil, Chile, Cuba, Spain, Mexico, Peru, Portugal, and Uruguay.

Climatic groups in Ibero-America viticulture compared to worldwide wine producer regions.

The wine production is an important activity in many Ibero-American countries. The wine producer regions of these countries configure a large use of different climate types and viticultural climates. In a vitivinicultural zoning project of CYTED (Ibero-American Program for Science, Technology and Development), a viticultural climatic characterization was done in this macro viticultural region. The project have assembled a climatic database that characterizes the viticultural regions, including relevant variables for viticulture: air temperature (mean, maximum, and minimum), precipitation, relative humidity, solar radiation, number of sunshine hours, wind speed, and evapotranspiration. Using indices of the Geoviticulture MCC System (HI, CI and DI), more than 70 viticultural regions in different countries (Argentina, Bolivia, Brazil, Chile, Cuba, Spain, Mexico, Peru, Portugal and Uruguay) were characterized according to its viticultural climatic. The results, which will be integrated to the worldwide database of the MCC System, showed that the Ibero-American viticulture is placed in a wide range of climatic groups of the wine producing regions around the world. This article presents the climatic groups found in Ibero-America, identifying also some new climatic groups not yet found in other regions of the world. This work also identifies some climatic groups not found in Ibero-America viticulture. The research has also highlighted viticultural areas characterized by climates with ?intra-annual climatic variability?, with the potential to produce more than one growing cycle per year. The results allow to conclude that the wide variability and climatic diversity present in Ibero-America may be one of the reasons to explain the diversity in terms of wine types, sensorial characteristics, typicity and uniqueness of wines produced on this macro-region.

What shapes attitudes toward paying taxes? Evidence from multicultural European countries

Objectives. Considerable evidence suggests that enforcement efforts cannot fully explain the high degree of tax compliance. To resolve this puzzle of tax compliance, several researchers have argued that citizens' attitudes toward paying taxes, defined as tax morale, helps to explain the high degree of tax compliance. However, most studies have treated tax morale as a black box, without discussing which factors shape it. Additionally, the tax compliance literature provides little empirical research that investigates attitudes toward paying taxes in Europe. Methods. Thus, this article is unique in its examination of citizen tax morale within three multicultural European countries, Switzerland, Belgium, and Spain, a choice that allows far more detailed examination of the impact of culture and institutions using data sets from the World Values Survey and the European Values Survey. Results. The results indicate the tendency that cultural and regional differences affect tax morale. Conclusion. The findings suggest that higher legitimacy for political institutions leads to higher tax morale.

Contribution of industry-based student learning performance for the STEM education

We hypothesized that Industry based learning and teaching, especially through company assigned student projects or training programs, is an integral part of science, technology, engineering and mathematics (STEM) education. In this paper we show that industry-based student training and experience increases students’ academic performances independent to the organizational parameters and contexts. The literature on industry-based student training focuses on employability and the industry dimension, and neglects in many ways the academic dimension. We observed that the association factors between academic attributes and contributions of industry-based student training are central and vital to the technological learning experiences. We explore international initiatives and statistics collected of student projects in two categories: Industry based learning performances and on campus performances. The data collected were correlated to five (5) universities in different industrialized countries, e.g., Australia N=545 projects, Norway N=279, Germany N=74, France N=107 and Spain N=802. We analyzed industry-based student training along with company assigned student projects compared with in comparisons to campus performance. The data that suggests a strong correlation between industry-based student training per se and improved performance profiles or increasing motivation shows that industry-based student training increases student academic performance independent of organizational parameters and contexts. The programs we augmented were orthogonal to each other however, the trend of the students’ academic performances are identical. An isolated cohort for the reported countries that opposed our hypothesis warrants further investigation.

De Jiménez de Asúa a Perón : sus exilios como componentes de la política exterior hispano-argentina

Resumen: El compromiso vital de Jiménez de Asúa con sus ideas y con la España republicana, lanzará al eminente jurista al exilio en la Argentina, donde su prestigio intelectual le permitirá retomar su vida académica. Al encarnar la oposición legal en el exterior contra el solidificado régimen franquista, colocará su protagonismo en una situación cercana al poder desestabilizador del exilio en España del mismo Perón. La política exterior de la Argentina y de España, por diferentes vías de intervención, pero sin definiciones drásticas, procurará influir indirectamente para neutralizar a ambos.
