Contributo das organizações do terceiro setor no desenvolvimento dos países de píngua pficial portuguesa

O empreendedorismo social é um campo que tem vindo a ganhar uma importância crescente nas sociedades atuais, sendo reconhecido como uma ferramenta útil na promoção do desenvolvimento sustentável. Como se trata de um campo emergente, apresenta-se ainda pouco explorado. Em Cabo Verde não existem ainda estudos sobre o tema, embora existam já algumas iniciativas de empreendedorismo social. A investigação foi desenvolvida de forma a responder ao objetivo de se conhecer qual o contributo que as Organizações Não Governamentais para o Desenvolvimento (ONGD) portuguesas têm dado para a sedimentação do empreendedorismo social em Cabo Verde. Assim, procurou-se apurar e analisar as ONGD que desenvolvem projetos em Cabo Verde, as áreas em que estas atuam para promoverem o desenvolvimento economico-social, os meios de financiamentos a que recorrem, as dificuldades encontradas no desenvolvimento das suas atividades, bem como compreender a razão que levou a que Cabo Verde fosse beneficiado com as ações dessas ONGD. Para conseguir atingir estas metas recorreu-se à metodologia qualitativa onde se fez uma análise exploratória e descritiva. A técnica utilizada para a recolha da informação primária foi a entrevista dirigida aos responsáveis de seis ONGD portuguesas que atuam em Cabo Verde, nomeadamente a Associação para a Cooperação Entre os Povos, a Associação de Defesa do Património de Mértola, Instituto Marquês de Valle Flôr, Meninos do Mundo, Terras Dentro e a Associação Raia Histórica. Os resultados deste estudo permitiram identificar que as ONGD portuguesas agem impulsionando o empreendedorismo social em Cabo Verde através da promoção do desenvolvimento integrado e sustentável, apoiado em parcerias estabelecidas com outras organizações locais caboverdeanas. Estes parceiros são atores chave que estão no terreno e possuem o conhecimento da realidade do país. Cabo Verde foi beneficiado pelos projetos por pertencer aos Países Africanos de Língua Oficial Portuguesa e/ou à Comunidade dos Países de Língua Portuguesa. Na obtenção de recursos, a maioria das ONGD portuguesas recorre a recursos em espécie e a voluntários portugueses, desempenhando estes o papel de formadores. A geração de valor social por parte destas entidades é feita muitas vezes de uma forma indireta, através da criação de valor económico que depois se repercute em valor social. Este valor social resulta da sua atuação em várias áreas como a saúde e segurança alimentar, desenvolvimento rural, meio ambiente, educação e formação profissional, emprego, economia alternativa ou microcrédito, pobreza e exclusão social, ambiente, habitação, promoção social e do turismo, capacitação e reforço institucional e coerência das políticas públicas para o desenvolvimento. Sendo Cabo Verde um arquipélago, as principais dificuldades encontradas pelas ONGD na sua atuação prende-se com a acessibilidade às ilhas devido à falta de transportes e meios de comunicação.

Delineating environmental groundwater vulnerability and protection zones mapping in fractured rock masses

Hard‐rock watersheds commonly exhibit complex geological bedrock and morphological features. Hydromineral resources have relevant economic value for the thermal spas industry. The present study aims to develop a groundwater vulnerability approach in Caldas da Cavaca hydromineral system (Aguiar da Beira, Central Portugal) which has a thermal tradition that dates back to the late 19th century, and contribute to a better understanding of the hydrogeological conceptual site model. In this work different layers were overlaid, generating several thematic maps to arrive at an integrated framework of several key‐sectors in Caldas da Cavaca site. Thus, to accomplish a comprehensive analysis and conceptualization of the site, a multi‐technical approach was used, such as, field and laboratory techniques, where several data was collected, like geotectonics, hydrology and hydrogeology, hydrogeomorphology, hydrogeophysical and hydrogeomechanical zoning aiming the application of the so‐called DISCO method. All these techniques were successfully performed and a groundwater vulnerability to contamination assessment, based on GOD‐S, DRASTIC‐Fm, SINTACS, SI and DISCO indexes methodology, was delineated. Geographical Information Systems (GIS) technology was on the basis to organise and integrate the geodatabases and to produce all the thematic maps. This multi‐technical approach highlights the importance of groundwater vulnerability to contamination mapping as a tool to support hydrogeological conceptualisation, contributing to better decision‐making of water resources management and sustainability.

Análise do ciclo de vida da produção do butanol

Este trabalho teve como objetivo avaliar e comparar os impactes ambientais da produção do butanol considerando três processos produtivos: um que usa fontes fósseis e dois que usam fontes renováveis, nomeadamente palha de trigo e milho. Para o primeiro caso considerouse o processo oxo e os restantes usaram o processo de produção ABE (acetona, butanol e etanol). Na primeira etapa estudaram-se e descreveram-se os diferentes processos referidos. A análise do ciclo de vida foi depois aplicada efetuando as quatro fases nomeadamente definição do âmbito e objetivo, inventário, avaliação de impactes e interpretação dos resultados obtidos. O inventário foi efetuado tendo em conta a bibliografia existente sobre estes processos e com o auxílio da base de dados Ecoinvent Versão3 Database™. Na avaliação de impactes utilizou-se o método Impact 2002 + (Endpoint). Concluiu-se que a produção do butanol pelo processo ABE utilizando o milho é a que apresenta maior impacte ambiental e a que produção do butanol pelo processo ABE usando a palha de trigo é a que apresenta um menor impacte ambiental, quando o processo de alocação foi efetuado tendo em conta as massas de todos os produtos produzidos em cada processo. Foi efetuada uma análise de sensibilidade para a produção de butanol usando palha de trigo e milho relativa aos dados de menor qualidade. No processo da palha de trigo fez-se variar a quantidade de material enviado para a digestão anaeróbia e a quantidade de efluente produzida. No processo relativo ao milho apenas se fez variar a quantidade de efluente produzida. As variações tiveram um efeito pouco significativo (<1,3%) no impacte global. Por fim, efetuou-se o cálculo dos impactes considerando uma alocação económica que foi executada tendo em conta os preços de venda para o ano 2013 na Europa, para os produtos produzidos pelos diferentes processos. Considerando o valor económico verificou-se um aumento do peso relativo ao butanol, o que fez aumentar significativamente o impacte ambiental. Isto deve-se em grande parte ao baixo valor económico dos gases formados nos processos de fermentação. Se na alocação por massa for retirada a massa destes gases os resultados obtidos são similares nos dois tipos de alocação.

Cell wall degrading enzymes and interaction between Trichoderma Aggressivum and Agaricus Bisporus

Agaricus bisporus is the most commonly cultivated mushroom in North America and has a great economic value. Green mould is a serious disease of A. bisporus and causes major reductions in mushroom crop production. The causative agent of green mould disease in North America was identified as Trichoderma aggressivum f. aggressivum. Variations in the disease resistance have been shown in the different commercial mushroom strains. The purpose of this study is to continue investigations of the interactions between T. aggressivum and A. bisporus during the development of green mould disease. The main focus of the research was to study the roles of cell wall degrading enzymes in green mould disease resistance and pathogenesis. First, we tried to isolate and sequence the N-acetylglucosaminidase from A. bisporus to understand the defensive mechanism of mushroom against the disease. However, the lack of genomic and proteomic information of A. bisporus limited our efforts. Next, T. aggressivum cell wall degrading enzymes that are thought to attack Agaricus and mediate the disease development were examined. The three cell wall degrading enzymes genes, encoding endochitinase (ech42), glucanase (fJ-1,3 glucanase) and protease (prb 1), were isolated and sequenced from T. aggressivum f. aggressivum. The sequence data showed significant homology with the corresponding genes from other fungi including Trichoderma species. The transcription levels of the three T. aggressivum cell wall degrading enzymes were studied during the in vitro co-cultivation with A. bisporus using R T -qPCR. The transcription levels of the three genes were significantly upregulated compared to the solitary culture levels but were upregulated to a lesser extent in co-cultivation with a resistant strain of A. bisporus than with a sensitive strain. An Agrobacterium tumefaciens transformation system was developed for T. aggressivum and was used to transform three silencing plasmids to construct three new T. aggressivum phenotypes, each with a silenced cell wall degrading enzyme. The silencing efficiency was determined by RT-qPCR during the individual in vitro cocultivation of each of the new phenotypes with A. bisporus. The results showed that the expression of the three enzymes was significantly decreased during the in vitro cocultivation when compared with the wild type. The phenotypes were co-cultivated with A. bisporus on compost with monitoring the green mould disease progression. The data indicated that prbi and ech42 genes is more important in disease progression than the p- 1,3 glucanase gene. Finally, the present study emphasises the role of the three cell wall degrading enzymes in green mould disease infection and may provide a promising tool for disease management.

Impact des coupes partielles sur l’activité de coléoptères phloeophages et xylophages en forêt boréale

Ce projet de recherche évalue la réponse à court terme de coléoptères phloeophages et xylophages (Cerambycidae et Scolytinae) à différentes intensités de coupes partielles (0, 25 et 40% de la surface terrière prélevée) afin de déterminer la viabilité de cette méthode sylvicole en forêt boréale. Disposant de 12 parcelles expérimentales (4 répétitions pour chaque intensité de coupe) dans une sapinière à bouleau blanc située au sud de la forêt boréale (Québec, Canada), nous avons évalué l’abondance, la diversité ainsi que l’établissement (taux d’attaque) de ces deux groupes d’insectes, et ce dès la première année suivant la coupe. L’échantillonnage a été réalisé à l’aide de pièges à interception multidirectionnelle et de l’écorçage de sections de 3 espèces d’arbres exposées dans l’ensemble des parcelles. Nos résultats montrent une plus grande activité/abondance des deux taxons (abondance 5 à 6 fois plus élevée) ainsi qu’une composition en espèces différente et plus diversifiée dans les peuplements partiellement coupés (25 et 40%). De plus, la présence et la distribution d’espèces colonisant habituellement des hôtes affaiblis (e.g., Trypodendron lineatum, Rhagium inquisitor) – et pouvant donc réduire la valeur économique d’arbres résiduels – a été recensée et semble être favorisée entres autres par l’ouverture de la canopée et des blessures physiques faites aux arbres pendant les opérations sylvicoles. Par ailleurs, l’approche combinant différentes techniques d’échantillonnage a permis une meilleure compréhension des mécanismes de localisation/sélection d’hôte (variant en fonction de l’espèce), un aspect important de la dynamique des insectes pour l’évaluation des risques suite aux coupes forestières. Sur la base de cette étude à court terme, il ne semblerait pas y avoir de différence significative sur les risques pour le milieu quant à l’augmentation d’activité des Cerambycidae et Scolytinae entre les deux traitements de coupe appliqués. Il reste cependant indispensable de vérifier la validité de ces résultats sur une plus longue période afin d’établir des plans d’aménagement forestier durables pour la forêt boréale.

Évaluation économique des services écosystémiques dans la région de Montréal : analyse spatiale et préférences exprimées

Les services écosystémiques (SE) réfèrent aux bénéfices que produisent et soutiennent la biodiversité et les écosystèmes et qui profitent à l’être humain. Dans beaucoup de cas, ils ne sont pas pris en compte dans le système économique. Cette externalisation des SE engendre des décisions sur l’utilisation du territoire et des ressources naturelles qui ignorent leur contribution à la qualité de vie des communautés. Afin notamment de sensibiliser l’opinion publique à l’importance des SE et de mieux les intégrer dans les processus décisionnels, ont été développées des démarches d’évaluation économique des SE. Dans cette thèse, nous avons cherché à comprendre à la fois comment l’utilisation passée et actuelle des sols dans la région de Montréal affecte la valeur des SE et comment ces aménités naturelles sont perçues et valorisées par la population, dans une perspective d’aménagement futur du territoire. Pour ce faire, nous avons utilisé deux approches : l’analyse spatiale recourant aux systèmes d’information géographique et l’analyse des préférences exprimées par des techniques d’enquête. Pour l’analyse spatiale, nous avons combiné des analyses cartographiques à des valeurs monétaires associées aux SE publiées dans la littérature. Nous avons alors estimé la valeur des écosystèmes d’un territoire par le transfert de bénéfices, de prix de marchés directs et de coûts évités. Cette démarche nous a permis de comprendre la relation entre l’utilisation actuelle du territoire du Grand Montréal écologique et la valeur des services fournis par les écosystèmes, que nous avons estimée à 2,2 milliards de dollars par année. Elle nous a permis aussi de mesurer les effets sur la valeur des SE du changement d’utilisation des sols entre les années 1960 et 2010. Nous avons montré que malgré différentes politiques de contrôle et d’encadrement de l’étalement urbain au cours de cette période, les pertes économiques non marchandes liées aux SE s’élèvent à 236 millions de dollars par année. Pour l’analyse des préférences exprimées, nous avons utlilisé deux méthodes, l’évaluation contingente et le choix multi-attributs, avec l’objectif de mesurer le consentement à payer de répondants pour des variations dans l’aménagement du territoire. Nous avons montré d’une part que les répondants valorisent significativement l’incidence des pratiques agro-environnementales sur la qualité de l’environnement et des paysages en consentant à payer entre 159 et 333 dollars par ménage par année pour une amélioration de la diversité du paysage agricole. D’autre part, leur volonté à payer pour l’amélioration de l’état des milieux humides du Québec est estimée entre 389 et 455 dollars par ménage par année. L’utilisation conjointe des deux méthodes nous a permis d’en comparer les résultats. Nous avons en outre démontré que le choix du format de question de valorisation de l’évaluation contingente affecte la convergence des résultats. Enfin, nous avons proposé des pistes de recherches futures portant sur l’intégration des démarches d’analyse biophysique, économique et politique dans des outils de prise de décision mieux adaptés à la dynamique des écosystèmes, de la biodiversité et des communautés humaines.

Studies on the seaweeds of andaman and nicobar group of islands

The importance of marine algae, often referred to as seaweeds, has been felt over a long time and is appreciated more and more in modern times. The economic value of marine algae is understood both indirectly and directly. The indirect benefit is due to the role of marine phytoplankton as well as the benthic macrophyte biomass along the shore and in the continental shelf, in primary production of the sea. Direct benefit includes the use of marine algae as food, feed, fertilizer and as source of various products of commercial importance such as agar and alginic acid. Hence to understand the potential resources of seaweeds, their distribution, density, standing crop and interrelated environmental parameters, a detailed study (survey and ecological work) was carried out for a period of 20 months from August 1988 to March 1990 in South Andaman, North Andaman, Middle Andaman, Havelock, Neil, Car Nicobar, Terassa, Chowra and Bumpoka islands. However in South Andaman, data were collected from five fixed stations fortnightly during this period for the purpose of modelling and system analysis.

Brachyuran Crabs of Cochin Backwaters- Diversity, Habitat Ecology and Systematics, with special emphasis to Genus Scylla

Among the decapod crustaceans, brachyuran crabs or the true crabs occupy a very significant position due to their ecological and economic value. Crabs support a sustenance fishery in India, even though their present status is not comparable to that of shrimps and lobsters. They are of great demand in the domestic market as well as in the foreign markets. In addition to this, brachyuran crabs are of great ecological importance. They form the conspicuous members of the mangrove ecosystems and play a significant role in detritus formation, nutrient recycling and dynamics of the ecosystem. Considering all these factors, crabs are often considered to be the keystone species of the mangrove ecosystem. Though several works have been undertaken on brachyuran crabs world –wide as well as within the country, reports on the brachyuran crabs of Kerala waters are very scanty. Most of the studies done on brachyuran fauna were from the east coast of India and a very few works from the west coast. Among the edible crabs, mud crabs belonging to genus Scylla forms the most important due to their large size and taste. They are being exported on a large scale to the foreign markets like Singapore, Malaysia and Hong Kong. Kerala is the biggest supplier of live mud crabs and Chennai is the major centre of live mud crab export. However, there exists considerable confusion regarding the identification of mud crabs because of the subtle morphological differences between the species.In this context, an extensive study was undertaken on the brachyuran fauna of Cochin Backwaters, Kerala, India, to have a basic knowledge on their diversity, habitat preference and systematics. The study provides an attempt to resolve the confusion pertaining in the species identification of mud crabs belonging to Genus Scylla. Diversity study revealed the occurrence of 23 species of brachyuran crabs belonging to 16 genera and 8 families in the study area Cochin Backwaters. Among the families, the highest number of species was recorded from Family Portunidae .Among the 23 crab species enlisted from the Cochin backwaters, 5 species are of commercial importance and contribute a major share to the crustacean fishery of the Cochin region. It was observed that, the Cochin backwaters are invaded by certain marine migrant species during the Post monsoon and Pre monsoon periods and they are found to disappear with the onset of monsoon. The study reports the occurrence of the ‘herring bow crab’ Varuna litterata in the Cochin backwaters for the first time. Ecological studies showed that the substratum characteristics influence the occurrence, distribution and abundance of crabs in the sampling stations rather than water quality parameters. The variables which affected the crab distribution the most were Salinity, moisture content in the sediment, organic carbon and the sediment texture. Besides the water and sediment quality parameters, the most important factor influencing the distribution of crabs is the presence of mangroves. The study also revealed that most of the crabs encountered from the study area preferred a muddy substratum, with high organic carbon content and high moisture content. In the present study, an identification key is presented for the brachyuran crabs occurring along the study area the Cochin backwaters and the associated mangrove patches, taking into account the morphological characters coupled with the structure of third maxillipeds, first pleopods of males and the shape of male abdomen. Morphological examination indicated the existence of a morphotype which is comparable with the morphological features of S. tranquebarica, the morphometric study and the molecular analyses confirmed the non existence of S. tranquebarica in the Cochin backwaters.

Administrative authorization for the demolition of urban rental units pursuant to the law of 1964: a spanish example of problematic over-activity in the application of transitional laws

Transitional provisions are defined as the set of regulations that rule juridical relationships on the occasion of a legislative change. Out of this context of law succession, their indiscriminate application can lead to serious inconsistencies. The analysis of a Spanish private law example is offered to illustrate this fact. It concerns the administrative authorization for the demolition of rented buildings in the cities. A regulation repealed more than fifteen years ago and however widespread utilised on ancient constructions that, after recent urban development, have acquired great economic value; something that in the end explains the current importance of such provisions. What is happening in Spain: denaturalization of the original  figure due to a mixture of formalist interpretations and speculative market interests, is presented here to call the attention on the necessary limitation of transitional provisions’ effects.

Metodologías de valoración de empresas

La valoración de una empresa como sistema dinámico es bastante compleja, los diferentes modelos o métodos de valoración son una aproximación teórica y por consiguiente simplificadora de la realidad. Dichos modelos, se aproximan mediante supuestos o premisas estadísticas que nos permiten hacer dicha simplificación, ejemplos de estos, son el comportamiento del inversionista o la eficiencia del mercado. Bajo el marco de un mercado emergente, este proceso presenta de indistinta forma retos paracualquier método de valoración, dado a que el mercado no obedece a los paradigmas tradicionales. Lo anterior hace referencia a que la valoración es aún más compleja, dado que los inversionistas se enfrentan a mayores riesgos y obstáculos. Así mismo, a medida que las economías se globalizan y el capital es más móvil, la valoración tomaráaún más importancia en el contexto citado. Este trabajo de gradopretende recopilar y analizar los diferentes métodos de valoración, además de identificar y aplicar aquellos que se reconocen como “buenas prácticas”. Este proceso se llevó a cabo para una de las empresas más importantes de Colombia, donde fundamentalmente se consideró el contexto de mercado emergente y específicamente el sector petrolero, como criterios para la aplicación del tradicional DCF y el práctico R&V.
