Повний текст джерелаNos últimos anos, a Web de dados está sendo rapidamente preenchida com dados de biodiversidade. No entanto, quando pesquisadores precisam recuperar, integrar e visualizar esses dados, eles precisam confiar em abordagens semi-manuais. Isso ocorre devido ao fato de que repositórios sobre biodiversidade, como GBIF, oferecem dados como cadeias de caracteres em planilhas no formato CSV. Não há nenhum metadado legível por máquinas que poderia acrescentar significado (semântico) aos dados. Sem os metadados, soluções automáticas são impossíveis, sendo necessário para visualização e integração dos dados, a utilização de abordagens semi-manuais. Para reduzir esse problema, apresentamos uma arquitetura chamada STBioData. Com ela é possível vincular automaticamente dados de biodiversidade, com informações espaço-temporais provenientes de fontes heterogêneas, tornando mais fácil a pesquisa, visualização e download dos dados relevantes. Ele suporta a geração de mapas interativos e o mapeamento entre dados de biodiversidade e ontologias que os descrevem (como Darwin Core, DBpedia, GeoSPARQL, Time e PROV-O). Foi proposto um novo modelo de proveniência para biodiversidade (BioProv), que estende o modelo de dados PROV W3C. BioProv permite que aplicativos que lidam com dados de biodiversidade incorporem os dados de proveniência em suas informações. Foi implementado um protótipo Web baseado nesta arquitetura. Ele oferece suporte aos especialistas do domínio de biodiversidade em tarefas como, identificação do status de conservação da espécie, além de automatizar a maioria das tarefas necessária. Foi utilizado coleções de dados de importantes pesquisas brasileiras sobre biodiversidade, juntamente com dados de distribuição geográfica das espécies e seu estado de conservação, provenientes da lista de espécies ameaçadas da IUCN (Red List). Esses dados são convertidos em dados conectados, enriquecidos e salvados como triplas RDF. Os usuários podem acessar o sistema, usando uma interface web que permite procurar, utilizando os nomes das espécies, intervalos de tempo e localização geográfica. Os dados recuperados podem ser visualizados no mapa interativo. O conteúdo de registros também é mostrado (incluindo dados de proveniência), juntamente com links para os registros originais no GBIF e IUCN. Os usuários podem exportar o conjunto de dados, como um arquivo CSV ou RDF, ou salvar em PDF (incluindo as visualizações). Escolhendo diferentes intervalos de tempo, os usuários podem por exemplo, verificar a evolução da distribuição das espécies. O protótipo STBioData foi testado usando casos de uso. Para esses testes, 46.211 registros de coleção do SpeciesLink e 38.589 registros de estado de conservação da IUCN (incluindo mapas), sobre mamíferos marinhos, foram convertidos em 2.233.782 triplas RDF. Essas triplas reutilizam ontologias representativas da área . 90% dos especialistas em biodiversidade, usaram a ferramenta para determinar o estado de conservação, eles foram capaz de encontrar as informações sobre determinada espécie de golfinho, com um tempo de recuperação satisfatório e também foram capaz de entender o mapa interativo gerado. Em um experimento sobre recuperação de informações, quando comparado com o sistema de busca por palavra-chave utilizado pela base SpeciesLink, a busca semântica realizada pelo protótipo STBioData, em média, é 24% melhor em testes de precisão e 22% melhor em testes de revocação. Não são considerados os casos onde o protótipo somente retornou o resultado da busca. Esses resultados demonstram o valor de ter dados conectados sobre biodiversidade disponíveis publicamente em um formato semântico.

A e-Science se caracteriza pela manipulação de um vasto volume de dados e utilização de recursos computacionais em larga escala, muitas vezes localizados em ambientes distribuídos. Nesse cenário, representado por alta complexidade e heterogeneidade, torna-se relevante o tratamento da proveniência de dados, que tem por objetivo descrever os dados que foram gerados ao longo da execução de um experimento científico e apresentar os processos de transformação pelos quais foram submetidos. Assim, a proveniência auxilia a formar uma visão da qualidade, da validade e da atualidade dos dados produzidos em um ambiente de pesquisa científica. O SciProv consiste em uma arquitetura cujo objetivo é interagir com sistemas de gerenciamento de Workflows científicos para promover a captura e a gerência dos metadados de proveniência gerados. Para esse propósito, o SciProv adota uma abordagem baseada em um modelo abstrato para a representação da proveniência. Esse modelo, denominado Open Provenance Model, confere ao SciProv a capacidade de prover uma infraestrutura homogênea e interoperável para a manipulação dos metadados de proveniência. Como resultado, o SciProv permite disponibilizar um arcabouço para consulta às informações de proveniência geradas em um cenário complexo e diversificado de e-Science. Mais importante, a arquitetura faz uso de tecnologia web semântica para processar as consultas aos metadados de proveniência. Nesse contexto, a partir do emprego de ontologias e máquinas de inferências, o SciProv provê recursos para efetuar deduções sobre os metadados de proveniência e obter resultados importantes ao extrair informações adicionais além daquelas que encontram-se registradas de forma explícita nas informações gerenciadas.
E-Science is characterized by manipulation of huge data set and large scale computing resources usage, often located in distributed environments. In this scenario, represented by high complexity and heterogeneity, it becomes important to treat data provenance, which aims to describe data that were generated during a scientific experiment execution and presents processes of transformation by which underwent. Thus, lineage helps to form a quality, validity and topicality vision of data produced in a scientific research environment. SciProv consists of an architecture that aims to interact with scientific workflows management systems for capture and manipulation of generated provenance metadata. For this purpose, SciProv adopts an approach based on an abstract model for representing the lineage. This model, called Open Provenance Model, provides to SciProv the ability to set up a homogeneous and interoperable infrastructure for handling provenance metadata. As a result, SciProv is able to provide a framework for query data provenance generated in a complex and diverse e-Science scenario. More important, the architecture makes use of semantic web technology to process metadata provenance queries. In this context, using ontologies and inference engines, SciProv provides resources to make inferences about lineage and to obtain important results in allowing the extraction of information beyond those that are registered explicitly from managed data.

The quality of the geographic data must be a relevant concern for providers and consumers of this type of data because the manipulation and analysis of low quality geographic data may result in errors, which will be propagated through the consequent data. Thus it is important to properly document the information which allows for certifying the quality of the geographic data. In order to provide a minimum amount of metadata for such purpose, this dissertation presents an approach based on the provenance of the geographic data, which corresponds to the information about the history of such data from its origin until the processes that resulted in its current state. For this purpose, a provenance model called ProcGeo was proposed, in which it was defined a minimum amount of metadata that must be considered for the analysis of the quality of a certain geographic data. Although a few works and geographic metadata standards, such as Federal Geographic Data Committee (FGDC) and ISO 19115, consider the information about the provenance in the analysis of the quality of geographic data, it´s the opinion of the author that some metadata considered important for this purpose are not adequately contemplated. In this work, the prototype of an interface called ProcGeoInter was also implemented, aiming to guarantee the completeness and correctness in the filling out of the defined metadata in the ProcGeo model as well as the visualization of their content. The validation of the ProcGeo model and of the ProcGeoInter interface were made through tests and surveys applied to providers and consumers of geographic data. As a means of comparison, the interface for filling out and visualization of metadata available by SIG Quantum GIS (plugin Metatools) was used, which implements the FGDC geographic metadata standard. The obtained results indicated that the metadata defined in the ProcGeo model helped the geographic data provider in the description of the provenance of such data, when compared to those defined in the FGDC geographic metadata standard. Through the consumer´s focus it was possible to notice that the information filled out in the metadata defined by the ProcGeo favored the analysis of the quality of the consumed data. It was clear that both providers and consumers do not possess the habit of providing or consuming the information predicted in the FGDC and ISO 19115 geographic metadata standards.
A qualidade do dado geográfico deve ser uma preocupação relevante para provedores e consumidores desse tipo de dado, pois a manipulação e análise de um dado geográfico com baixa qualidade podem resultar em erros que vão se propagar nos dados gerados a partir desse. Assim, é importante que a informação que permita atestar a qualidade do dado geográfico seja adequadamente documentada. Com o propósito de oferecer um conjunto mínimo de metadados para essa finalidade, esse trabalho apresenta uma abordagem baseada na procedência do dado geográfico, que corresponde à informação sobre a história do dado, desde a sua origem até os processos que resultaram no seu estado atual. Para tanto, foi proposto um modelo de procedência denominado ProcGeo no qual foi definido um conjunto mínimo de metadados que devem ser considerados para a análise da qualidade de um dado geográfico. Embora alguns trabalhos e padrões de metadados geográficos, como o Federal Geographic Data Committee (FGDC) e o ISO 19115, considerem a informação da procedência para a análise da qualidade do dado geográfico, sob o ponto de vista da autora deste trabalho, alguns metadados considerados importantes para essa finalidade não são adequadamente contemplados. Neste trabalho também foi implementado o protótipo de uma interface denominada ProcGeoInter, que tem como finalidade garantir a corretude e completude do preenchimento dos metadados definidos no modelo ProcGeo e a visualização do conteúdo dos mesmos. A validação do modelo ProcGeo e da interface ProcGeoInter foram realizados por meio de testes e questionários aplicados a provedores e consumidores de dados geográficos. Para efeito de comparação, foi considerada a interface para preenchimento e visualização de metadados disponibilizada no SIG Quantum GIS (plugin Metatoools), que implementa o padrão de metadados geográficos FGDC. Os resultados obtidos indicaram que os metadados definidos no modelo ProcGeo auxiliaram o provedor de dados geográficos na descrição da procedência desses dados, quando comparados aos definidos no padrão de metadados geográficos FGDC. Pelo foco do consumidor foi possível perceber que as informações preenchidas nos metadados definidos pelo ProcGeo favoreceram a análise da qualidade dos dados consumidos. Ficou evidente que tanto provedores quanto consumidores não possuem o hábito de prover ou consumir as informações previstas nos padrões de metadados geográficos FGDC e ISO 19115.

Повний текст джерелаSistemas de informação, desenvolvidos para diversos setores econômicos, necessitam com maior freqüência capacidade de rastreabilidade dos dados. Para habilitar tal capacidade, é necessário modelar a proveniência dos dados. Proveniência permite testar conformidade com a legislação, repetição de experimentos, controle de qualidade, entre outros. Habilita também a identificação de agentes (pessoas, organizações ou agentes de software) e pode ser utilizada para estabelecer níveis de confiança para as transformações dos dados. Esta dissertação propõe um modelo genérico de proveniência criado com base no alinhamento de recortes de ontologias de alto nível, padrões internacionais e propostas de padrões que tratam direta ou indiretamente de conceitos relacionados à proveniência. As contribuições da dissertação são portanto em duas direções: um modelo conceitual para proveniência - bem fundamentado - e a aplicação da estratégia de projeto conceitual baseada em alinhamento de ontologias.
Information systems, developed for several economic segments, increasingly demand data traceability functionality. To endow information systems with such capacity, we depend on data provenance modeling. Provenance enables legal compliance, experiment validation, and quality control, among others . Provenance also helps identifying participants (determinants or immanents) like people, organizations, software agents among others, as well as their association with activities, events or processes. It can also be used to establish levels of trust for data transformations. This dissertation proposes a generic conceptual model for provenance, designed by aligning fragments of upper ontologies, international standards and broadly recognized projects. The contributions are in two directions: a provenance conceptual model - extensively documented - that facilitates interoperability and the application of a design methodology based on ontology alignment.

Повний текст джерелаThis essay describes the debate about the principle ofprovenance and its multiple forms, and the transformationsof these forms, due to the coming of electronic informations.The thesis intended to explain the definitions of the principlein a modern information management and there explore howthey operate proactively to assure provenance.The qualitative investigation was carried out at tenmunicipality final archives, where each municipalityarchivist was being interviewed. The study expounds in whatway the digitisation has simplified the methods to conductassured provenance, where automated metadata shows therelationships of the information to function and process. Theessay also debates the difficulties that appear when digitalinformation are being organized in different ways thananalogue information, and how this fact requires a newinterpretation of the principle of provenance.The researcher concludes that the investigated archives,ensure respect des fonds when it concerns the content of thearchives, but not when it comes to the whole content of theinformation management. The result of the study also showsthat the respect of original order as a reflection of theorganization, has to be understood throughout all content ofthe management and its logical order, rather than the visiblecontent that the archives embrace. Furthermore the thesisobserves the importance of proactivity, regarding theclarification of the relationships between the information andthe processes that produce and use them. This could beachieved with early application of metadata and developmentof systems that keep metadata trough all processes. Theconclusion of the essay is that this is not pursued in theextension that is required.

Повний текст джерелаData provenance is the set of metadata that allows for the identification of sources and transformations applied to data, since its creation to its current state. There are several advantages of incorporating data provenance into data integration processes, such as to estimate data quality and data reliability, to perform data audit, to establish the copyright and ownership of data, and to reproduce data integration decisions. In this master\'s thesis, we propose the MPPI, a novel data provenance model that supports data integration processes. The model focuses on systems in which only owners can update their data sources, i.e., the integration process cannot correct the sources according to integration decisions. The main goal of the MPPI model is to handle decisions taken by the user in previous integration processes, so they can be automatically reapplied in subsequent integration processes. The MPPI model introduces the following properties. It is based on mapping provenance data into operations of copy, edit, insert and remove, which are stored in an operation repository. It also provides four techniques to handle overlapping operations: blind, restrict, undo and redo. Furthermore, it identifies anomalies generated by sources that are updated between two data integration processes and proposes four validation approaches to avoid these anomalies: full validation, source validation, target validation and no validation. Moreover, it introduces two methods that perform the reapplication of operations according to decisions taken by the user, called the VRS (Validate and Reapply in Separate) and the VRT (Validate and Reapply in Tandem) methods, in addition to extending the VRT method with the safe reordering optimization. The MPPI model was validated through performance tests that investigated overlapping operations, the VRT method and the safe reordering optimization. The tests showed that the techniques proposed to handle overlapping operations are feasible to be applied to real integration systems. The results also demonstrated that the VRT method provided significant performance gains over data gathering when the goal is to reestablish previous integration results. The performance gains were of at least 93%. Furthermore, the performance results also showed that reordering the operations before the reapplication process can improve even more the performance of the VRT method

Повний текст джерелаReconciliation is the process of providing a consistent view of the data imported from different sources. Despite some efforts reported in the literature for providing data reconciliation solutions with asynchronous collaboration, the challenge of reconciling data when multiple users work asynchronously over local copies of the same imported data has received less attention. In this thesis we investigate this challenge. We propose AcCORD, an asynchronous collaborative data reconciliation model. It stores users integration decision in logs, called repositories. Repositories keep data provenance, that is, the operations applied to the data sources that led to the current state of the data. Each user has her own repository for storing the provenance. That is, whenever inconsistencies among imported sources are detected, the user may autonomously take decisions to solve them, and integration decisions that are locally executed are registered in her repository. Integration decisions are shared among collaborators by importing each others repositories. Since users may have different points of view, repositories may also be inconsistent. Therefore, AcCORD also introduces several policies that can be applied by different users in order to solve conflicts among repositories and reconcile their integration decisions. Depending on the applied policy, the final view of the imported sources may either be the same for all users, that is, a single integrated view, or result in distinct local views for each of them. Furthermore, AcCORD encompasses a decision integration propagation method, which is aimed to avoid that a user take inconsistent decisions over the same data conflict present in different sources, thus guaranteeing a more effective reconciliation process. AcCORD was validated through performance tests that investigated the proposed policies and through users interviews that investigated not only the proposed policies but also the quality of the multiuser reconciliation. The results demonstrated the efficiency and efficacy of AcCORD, and highlighted its flexibility to generate a single integrated view or different local views. The interviews demonstrated different perceptions of the users with regard to the quality of the result provided by AcCORD, including aspects related to consistency, acceptability, correctness, time-saving and satisfaction.

Повний текст джерелаSocial networks have gained a significant interest for society during our decade. These platforms allow users to produce, share and exchange various content. Twitter is one of the most popular social networks that allow users to publish messages, called tweets. These tweets may contain offensive texts, such as harassment or bullying messages, or information related to abnormal topics. Many research studies have shown how such social content can have an impact on users and cause psychological harm. Developing a system for detecting such type of messages is necessary to protect the user and predict tragic events. The work presented in this thesis is brought into the context of data mining from Twitter to identify and detect such messages. We propose a suspicious tweets detection system based on probabilistic topic models and fuzzy logic. In order to identify harassment tweets, we introduce a classification model that exploits a set of features and uses supervised learning algorithms. People also use social networks to search for relevant posts that satisfy their information need where this need is usually formulated using a textual query. Twitter’s messages are short and access to information is sometimes difficult because of the variety of published content and huge amount of data generated. The second part of this work deals with the context of social information retrieval and aims to improve tweets retrieval quality. We propose a query expansion approach to overcome the shortness of user queries and tweets by extracting frequent closed patterns and using word embeddings

Повний текст джерелаWaste reused has been promoted by the definition of final wastes (law of the 13/07/92). The impact of two scenarios against lentic ecosystems was studied : one deals with municipal solid waste incineration bottom ashes (MSWIBA) reused in road embankment, the other with under water deposition of dredged materials in a gravel pit. One of the purpose of yhis study was to complete the methodology for the assessment of waste ecocompatibility, focused by ADEME. The toxic potential of these materials have been distinguished and ordered according to their toxic potential. Four of the dredged materials were characterized by a high toxic potential and presented risks of lentic ecosystem eutrophisation. Risks of this storage scenario are not acceptable for these sediments. Recommendations have been made for the sediment amount to be submerged and for the constraints around thsese deposits. MSWIBA leachates impact was demonstrated whatever the methodology used. Copper seems to be responsible of the effects measured on species. It can be considered as a major pollutant of MSWIBA leachates. Risks of this reused scenario are not acceptable for lentic ecosystems. Recommendations have been made for MSWIBA reused as road embankment. With this study, the interest of microcosm assays have been emphasized. Yhis kind of approach was convenient for the evaluation of contaminated matrix impact against lentic ecosystems. Some aspects of this protocol have to be optimised in order to obtain acceptable variability levels for each parameter

Повний текст джерелаTsavorite, a (V, Cr, Mn)-bearing green grossular, is hosted by graphitic gneisses or calc-silicates, often asssociated with dolomitic marbles, and belonging to the Metamorphic Neoproterozoic Mozambique Belt. Tsavorite is found either as nodules or in quartz veins (primary deposits), or in placers (secondary deposits). The mineralogical study of tsavorites suggests a new protocol to certificate their geographical origin, based on the V/Cr ratio, Mn content and delta18O. The study of the Lemshuku and Namalulu deposits in Tanzania has shown that the metamorphism of organic matter-rich and evaporites-rich sedimentary protoliths occurred at P = 7.0 ± 0.4 kbar and T = 677 ± 14°C, at 634 ± 22 Ma (U-Th-Pb dating on monazite). The metamorphic series cooled down at around 500 Ma (40Ar-39Ar dating on muscovite). Two metasomatic stages are linked to the formation of tsavorite : (i) diffusion metasomatism forming nodules at P = 5.0-7.4 kbar and T = 580-691°C; (ii) calcitic infiltration metasomatism forming quartz veins at P = 3.6-4.9 kbar and T = 505-587°C. These last have been dated in situ with Sm-Nd dating at 606 ± 36 Ma. Continental evaporites, deposited in a coastal marine sabkha with (Si, Ca)-bearing sediments, transformed into tsavorite in the case of the nodules, while the molten salts are associated with the formation of the quartz veins. The mineralisations are controlled by lithostratigraphy and structure

Повний текст джерелаThe first part focuses on material analysis and process use for the manufacturing of funerary “models”. These wooden objects represent people or everyday scenes of life, used by Egyptian elites for funeral furniture between the end of the Old Kingdom to the end of the Middle Kingdom (cir. 2350-1630 BC). In a first part, focused on objects from Saqqara, Assiut and Meir, the stylistic and technical features were examined to define groups of objects and workshops. Then, dating criteria were defined and compared with the funeral furniture discovered in the studied graves. According to one unwound chronological since the end of the Old Kingdom, the second part concentrates on workshops and interregional contacts. A particular attention is worn in the relationship between royal power, elites and craftsmen through the sending of funeral equipment and more particularly bare wooden models of the Memphite area to the Upper Egypt. The third part is interested in the social, economic and religious functions of the models and examines more particularly the narrow relationship which unites this furniture and the funeral practices between the end of the Old Kingdom to the end of the Middle Kingdom. The second volume presents the corpus of the examined wooden models. The third volume is dedicated to appendices. The examination of wooden models, significant of political and religious deep changes at the origin of new customs and funeral faiths between the VIth and the XIIIth dynasty, specifies the geographical, historic and social context associated with the manufacturing. The analysis of these objects allows refining the perception of the relationship between craftsmen and power, omnipresent in the Egyptian society from the Predynastic period

Повний текст джерелаDetrital zircon ages obtained from the Corny Point Paragneiss and the Massena Bay Gneiss in the southeastern Gawler Craton, Australia, constrain their deposition to the interval ca. <1880 Ma. The presence of 2020 Ma, 2450 Ma and 2520 Ma detrital zircons within the Corny Point Paragneiss constrains the source region for the sedimentary protoliths to three possible domains within Australia; the Gawler Craton, the Glenburgh Orogen in the Western Australian Proterozoic, and the North Australian Craton, all of which contain rock systems with similar ages. Whole rock εNd (1850Ma) values from the Corny Point Paragneiss range from -1 to -5. These values potentially preclude the Late Archaean to mid Proterozoic crust of the Gawler Craton as a sole or major source region due to its highly evolved average εNd (1850Ma) of around -10. Preclusion of the Gawler Craton as a source is apparently confirmed by Hf isotopic compositions of 2020 Ma detrital zircons from the Corny Point Paragneiss, which have εHf (2020Ma) ranging between +3 to +7. This compares with εHf (2020Ma) of -1 to -4 for zircons from the 2020 Ma Miltalie Gneiss in the Gawler Craton. Available Nd isotopic data suggests that the Glenburgh Orogen is too crustally evolved to have provided the majority of sediment into the Corny Point Paragneiss protolith. The 2020 Ma detrital Hf isotopic compositions of the Corny Point Paragneiss are similar to the 2020 Ma Wildman Siltstone (εHf (2020Ma) +2 to +7) in the Pine Creek Orogen in the North Australian Craton. Two possible scenarios can be extrapolated from the detrital zircon and Nd isotopic data; (1) the Corny Point Paragneiss sediment was derived from a source region within the North Australian Craton and could share source regions with the Wildman Siltstone, or (2) the sediments were derived from a Gawler Craton source region that included a dominant juvenile component of the 2020 Ma Miltalie Gneiss in the adjacent Gawler Craton which has since been eroded. In the first scenario, the absence of connection to the Gawler Craton allows for the Betts and Giles (2006) plate reconstruction model, which proposes that the Corny Point Paragneiss formed part of the North Australia Craton, and was sutured to the Proto Gawler Craton at 1730-1700 Ma. The second scenario highlights a significant limitation in evaluating the significance of provenance data, particularly when considering old potential source terrains that have undergone significant levels of denudation. The proximity of the Corny Point Paragneiss to the rifted southern and eastern margins of the Australian Proterozoic means a thorough evaluation of the palaeogeographic significance of the Corny Point Paragneiss detrital signature requires corresponding datasets from regions such as Antarctica which were formerly contiguous with the Gawler Craton.

Повний текст джерелаThis thesis consists of three essays in resource economics. Chapter 2 analyzes the effects of resource storage on welfare and on the resource stock, in the context of rice-fish culture. I develop a simple general equilibrium model, that has three central components: one open access renewable resource with logistic natural growth, two production sectors and storage of the good produced with the resource. Consumers store the resource when they speculate that the price of the resource will be higher in the future. Storage has an ambiguous effect on welfare, has a negative impact on resource stock at the period the storage takes place and has a positive impact for all following periods. Chapter 3 examines the effects of migration of skilled workers in a model of interregional trade in the presence of pollution. I develop a two-sector model of trade that incorporates both pollution and migration issues to show that interregional trade can affect the pollution level of a country composed of regions with different industrial structures. The mobility of workers amplifies the effects of interregional trade on the environmental capital. The region with the less (more) polluting technology is affected positively (negatively) by trade. Migration doesn’t affect the trade pattern. The region with the less polluting manufacturing industry always gains from trade. If the preferences over manufactures is relatively low, the region with the more pollutant technology can experience a loss from trade in the long run. Finally, Chapter 4 is co-authored with Yves Richelle. In this chapter, we consider the problem of efficiently allocating water of a lake among different potential users. We consider two types of irreversibility: the irreversibility of an investment that creates a fixed damage to the ecosystem and the irreversibility of the right to use the resource that comes from the legislation (legislative irreversibility). First of all, we determine the value of water for users. Then, we characterize the optimal allocation of water among users. With legislative irreversibility, we show that it is sometimes optimal to reduce the amount of water allocated to the firm, even though there is no rivalry in use. Moreover, we show that it is not always optimal to prevent the damage created by the irreversible vi investment. We define the context, in which it is optimal to intervene to prevent the damage. Furthermore, with irreversibility, we prove that the marginal value of water at the efficient allocation for users is not equalized. Overall, we show that in the case of no rivalry in use, unused water should not be seen as a limitless resource to be used in any way whatever.
