Abstract:

Denne avhandlingen fokuserer på hvordan informasjon fra mange forskjellige samlinger kan gjøres lettere tilgjengelig for informasjonsbrukere. I dagens informasjonssamfunn finnes og produseres det store mengder digital informasjon, og mange organisasjoner og bedrifter anvender derfor beskrivende metadata til å organisere informasjonen sin i mange ulike samlinger/databaser. Dette fører til at personer som ønsker å søke etter informasjon, må forholde seg til tilsvarende mange forskjellige søkesystemer og søketeknikker. Fra disse brukernes ståsted er det ønskelig med et søkesystem som gjør det mulig å søke etter informasjon fra et stort antall samlinger/databaser på ett sted.

Problemstillingen som ligger til grunn for oppgaven er todelt. For det første skal det undersøkes hvordan man kan utforme en arkitektur som muliggjør samtidig søking i flere heterogene metadatabaser. For det andre skal det undersøkes hvordan denne arkitekturen kan anvendes til å bygge opp et enhetlig søkegrensesnitt som gir brukeren tilgang til ressursbeskrivelser fra alle de heterogene metadatabasene.

Forutsetningen for oppgaven er at arkitekturen skal baseres på metadatahøsting ved hjelp av OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting). Dessuten skal Fast Data Search anvendes som indekserings- og søkesystem.

I denne avhandlingen presenteres et forslag til et system som, basert på metadatahøsting fra flere forskjellige datakilder og påfølgende sentral indeksering av de innhøstede metadataene, tilbyr en enhetlig søketjeneste. Dette gjør det i praksis mulig å søke i innholdet fra mange datakilder gjennom ett felles søkegrensesnitt.

Datagrunnlaget i prototypen utgjøres av om lag 1400 metadatabeskrivelser som blir høstet fra tre av Nasjonalbibliotekets samlinger; Digitalt Radioarkiv, Galleri NOR og Mavis. Metadatahøstingen utføres av en OAI-høster som er en videreutvikling av en fritt tilgjengelig høsterapplikasjon med åpen kildekode. Alle metadataene er beskrevet i formatet MODS (Metadata Object Description Schema), som er et mer uttrykksfullt alternativ til Dublin Core. Etter en enkel normalisering, blir metadataene indeksert i Fast Data Search. Et webbasert søkegrensesnitt, med mulighet for både enkelt og avansert søk, gjør det mulig for brukerne å søke i alle de indekserte metadataene.

Hovedkonklusjonen er at metadatahøsting ved hjelp av OAI-PMH er en velegnet metode for å utvikle en felles søketjeneste for informasjon fra mange datakilder. Metoden fungerer også internt i en organisasjon/bedrift. Det er likevel viktig å være bevisst på at eksterne faktorer, som for eksempel variasjoner metadatakvalitet, kan påvirke kvaliteten på søketjenesten. Når metoden anvendes internt i en organisasjon/bedrift, kan det derfor være nyttig å undersøke datakildenes kvalitet på forhånd. På denne måten kan uegnede datakilder utelukkes på et tidlig tidspunkt.


This thesis focuses on how information from a lot of different collections can be made more easily available for information users. Today’s information society contains large amounts of digital information, and many organizations and enterprises therefore employ descriptive metadata when organizing their information in several different collections/databases. This diversity forces people wanting to search for information to deal with a corresponding number of different search systems and techniques. For these users, a search system which makes it possible to locate information from a large number of collections/databases at single spot is desirable.

The problem to be addressed in this thesis is split. Firstly it has to be examined how to model an architecture which supports simultaneous searching in heterogeneous metadatabases. Secondly it has to be examined how this architecture can be employed to build a uniform search interface which gives the user access to resource descriptions from all the heterogeneous metadatabases.

A premise for the thesis is that the architecture should be based on metadata harvesting by means of the OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting). In addition Fast Data Search should be used as the indexing and searching system.

This thesis presents a system suggestion which offers a uniform search service, based on metadata harvesting from several different data sources and subsequent central indexing of the harvested metadata. In practice this makes it possible to search the content of several data sources using one common search interface.

The data foundation in the prototype is constituted by about 1400 metadata descriptions harvested from three collections at the National Library of Norway: Digitalt radioarkiv (Digital Radio Archive), Galleri NOR (photo gallery) and Mavis (multimedia database). The harvesting process is performed by an OAI harvester which is an adaptation of an open source harvester application. All metadata is described using MODS (Metadata Object Description Schema), which is a more expressive alternative to Dublin Core. After a simple normalization process, the metadata is indexed by Fast Data Search. A web based search interface, enabling both basic and advanced search options, makes it possible for the users to search the indexed metadata.

The main conclusion is that metadata harvesting by means of OAI-PMH is a suitable method for developing a common search service for information from various data sources. The method is also applicable for internal use in an organization or enterprise. However, it is important to be conscious about external factors that may affect the quality of the search service, for instance variations in metadata quality. When the method is used internally in an organization/enterprise, it may be useful to examine the quality of the data sources in advance. By doing this, unsuitable data sources can be excluded early in the development process.

This work focuses on two aspects: the integration of a set of digital libraries, repositories and other data providers through the OAI-PMH protocol (Open Archives Initiative Protocol for Metadata Harvesting) and contextualized documents retrieval in this integrated repository. It is proposed the use of ontologies and content analysis of articles in wiki environments in the context definition. The interest in ontologies is in its use as artifacts of specification domain. An ontology is a data model that represents a set of concepts and their relationships within a domain of knowledge. A wiki is a collaborative environment, containing a collection of items connected by hyperlinks, which can be edited collectively by using a web browser. In this work, the wiki environments are used as an auxiliary repository of knowledge to the extraction of relevant terms. Thus, several concepts and relationships that may not be present in the ontology that specifies the domain of knowledge (since the construction of ontologies is a complex process) can be identified. The result of the developed tool processing is a ranking of documents ordered by a higher degree of importance with respect to the query provided by a user and a particular domain of knowledge, which is specified by an ontology.
Este trabalho aborda duas vertentes: a integração de um conjunto de bibliotecas digitais, repositórios e outros provedores de dados por meio do protocolo OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) e a recuperação contextualizada de documentos neste repositório integrado. Propõe-se a definição dos contextos utilizando ontologias e a análise do conteúdo de artigos de ambientes wiki. O interesse em ontologias está no seu uso como artefatos de especificação de domínios. Uma ontologia é um modelo de dados que representa um conjunto de conceitos e seus relacionamentos, dentro de um domínio de conhecimento. Um wiki é um ambiente colaborativo, que contêm uma coleção de artigos conectados através de hiperlinks, que podem ser editados coletivamente, através da utilização de um navegador web. Neste trabalho, os ambientes wiki são utilizados como um repositório de conhecimento auxiliar, para a extração de termos relevantes. Dessa forma, diversos conceitos e relacionamentos que podem não estar presentes na ontologia que especifica o domínio de conhecimento (uma vez que a construção de ontologias é um processo complexo) podem ser identificados. O resultado do processamento da ferramenta desenvolvida é um ranking de documentos ordenado por maior grau de relevância com relação à consulta fornecida por um usuário e a um determinado domínio de conhecimento, que é especificado por uma ontologia.

Abstract:
A publicação de trabalhos científicos é uma das principais formas de avanço da Ciência, dando aos autores o reconhecimento de seu trabalho por parte da comunidade científica. A divulgação de trabalhos publicados é de grande interesse tanto da parte de quem os desenvolve (autores), quanto de quem pode vir a se beneficiar dos resultados (a comunidade científica em geral). Neste contexto, as bibliotecas digitais surgem como uma alternativa para simplificar o processo de publicação de artigos. Nelas encontram-se repositórios de dados que possuem informações sobre os artigos publicados bem como links para os próprios artigos, ou mesmo os arquivos propriamente ditos. Dois pontos importantes na implementação e uso de bibliotecas digitais são a interoperabilidade e a padronização dos metadados que serão utilizados pelos repositórios. Essas questões podem ser resolvidas através da OAI (Open Archives Initiative) e pelo formato Dublin Core. Um exemplo de biblioteca digital que utiliza o padrão OAI é a BDBComp (Biblioteca Digital Brasileira de Computação), que disponibiliza os metadados sobre os artigos publicados nos eventos de computação no Brasil. Por outro lado, a SBC (Sociedade Brasileira de Computação) disponibiliza aos eventos que promove (e atualmente também a alguns eventos internacionais) o sistema JEMS para o gerenciamento das submissões dos artigos. Através dele os artigos são avaliados, e é feita a seleção daqueles que serão publicados em cada evento ou periódico que utiliza o sistema. Neste trabalho é apresentado um serviço de geração de metadados compatível com o padrão OAI, desenvolvido para disponibilizar os metadados sobre os artigos publicados nas conferências ou periódicos que utilizem o JEMS. Os metadados gerados são disponibilizados para bibliotecas digitais, como a BDBComp. O serviço é de fato um provedor de dados OAI, que utiliza dados provenientes do sistema JEMS e os disponibiliza no formato Dublin Core a bibliotecas digitais através do protocolo OAI-PMH, o qual é baseado em XML. Este provedor de dados foi desenvolvido para uso com a biblioteca digital da SBC, e oferece um aumento da quantidade e da qualidade dos metadados disponibilizados sobre os artigos publicados nos eventos e periódicos gerenciados pelo JEMS.
The publication of scientific works is one of the greatest forms of Science progress, giving the authors recognition from scientific community about their work. The publication spreading is of great interest for both the authors and those that can be benefited from the results. In this context, the digital libraries appear as an alternative to simplify the paper publication process. They own data repositories that have information about published papers as well as links for the papers. Two important points in the implementation and use of digital libraries are metadata interoperability and metadata standadization. These questions can be solved by the OAI (Open Archives Initiative) and by the Dublin Core format. An example of digital library that uses the OAI standard is BDBComp (Biblioteca Digital Brasileira de Computação), which have metadata about papers published in computing science events in Brazil. On the other hand, SBC (Sociedade Brasileira de Computação) have the JEMS system for use in the management of paper submission for the events that SBC promotes (and nowadays for some international events too). Through JEMS the papers are evaluated, and a selection of the accepted papers can be done. This work presents an OAI-compatible metadata generation service developed to offer metadata about the papers published in conferences or journals that use JEMS. The generated metadata are made available to digital libraries, like BDBComp. The service is in fact an OAI data provider that uses data obtained from JEMS and offer the metadata in the Dublin Core format to digital libraries, through the OAI-PMH protocol, which is based on XML. This data provider was developed for use with the SBC’s digital library. It gives an improvement on the quantity and quality of the available metadata about the papers published by the events and journals managed by JEMS.

O interesse na criação de Bibliotecas Digitais cresceu significativamente a partir do sur- gimento e da disseminação da Web, que trouxe consigo a necessidade de ferramentas que facilitassem a publica»c~ao, gerenciamento e a recupera»c~ao da informa»c~ao digital. Atual- mente, podemos observar uma ampla gama de Bibliotecas Digitais, que se caracterizam como servi»cos que gerenciam e disponibilizam documentos digitais, de forma mais es- truturada do que convencionalmente se observa na Web. Nesses servi»cos, em geral, os documentos s~ao descritos por metadados, recuperados atrav¶es de ferramentas de busca estruturada e visualizados em interfaces apropriadas.Uma das limita»c~oes de grande parte das Bibliotecas Digitais existentes ¶e a aus^encia de mecanismos de integra»c~ao de dados, de maneira a fornecer ao usu¶ario, acesso uni¯cado e transparente aos reposit¶orios gerenciados por diferentes servi»cos. Esse problema ¶e conhecido na literatura como o problema da Inte- roperabilidade entre Bibliotecas Digitais. Dentro desse contexto, desenvolvemos o Clio-i, um sistema para gerenciamento de Bibliotecas Digitais. A sua arquitetura apresenta ca- racter¶³sticas desej¶aveis como um m¶odulo de recupera»c~ao de documentos, um visualizador de documentos e dois m¶odulos para interoperabilidade entre reposit¶orios digitais. Para prover o mecanismo de interoperabilidade, foi implementada no Clio-i uma extens~ao do protocolo OAI-PMH (Open Archives Initiative-Protocol for Metadata Harvesting), que ¶e um padr~ao internacional para interoperabilidade de reposit¶orios digitais. A interopera- bilidade do Clio-i ¶e composto por dois m¶odulos: (1) o Clio-i Data Provider, respons¶avel por exportar os metadados dos documentos gerenciados localmente, de acordo com os padr~oes estabelecidos no OAI-PMH; e (2) o Clio-i Service Provider, que realiza a coleta de informa»c~oes a partir de qualquer provedor de dados remoto baseado em OAI-PMH. O prot¶otipo de sistema implementado foi validado em dois estudos de caso, operacionali- zando centenas de milhares de registros e efetivando a extens~ao do protocolo OAI-PMH adotada

Abstract:
L'organisation africaine de la propriété intellectuelle (OAPI) a consacré la théorie de l'épuisement des droits depuis sa révision de 1999. Elle en a posé les conditions légales. On découvre que ses conditions, qui sont une limitation du droit exclusif de commercialisation des titulaires, n'en préservent pas moins la quintessence. À travers une mise en circulation limitée au territoire national pour la marque et au territoire régional pour le brevet, le législateur a fait partiellement échec au libre commerce des produits protégés. L'existence des zones de libre-échange peut néanmoins contribuer à élargir le domaine de l'épuisement qui deviendra alors communautaire dans l'UEMOA et la CEMAC. L'encadrement de l'épuisement des droits est rigide mais maîtrisé. Il est cohérent avec le principe de départ qui est la protection des droits de propriété industrielle. Aussi l'épuisement international est-il tout simplement rejeté, alors même qu'il aurait pu constituer un moyen de régulation de la libre circulation des produits protégés. Néanmoins, il faut relativiser ce rôle et se tourner vers une véritable quête de transfert de technologie qui est le seul moyen de transformer le sort de la propriété industrielle sur le continent africain.

São apresentados os resultados de uma pesquisa que teve como objetivo propor um modelo de previsão da degradação, baseada numa análise determinística e estocástica, para contribuir no acompanhamento das Obras de Arte Especiais – OAEs do Brasil, sob responsabilidade do Departamento Nacional de Infraestrutura de Transporte – DNIT, e para banco de dados similares. No banco de dados do DNIT consta o inventário de quatro mil quinhentos e trinta e uma OAEs, com uma vistoria realizada entre 2012 a 2016 para todas as obras do inventario. Devido ao número insuficiente de registros históricos para o desenvolvimento de um modelo de previsão da degradação das OAEs, foram testados os modelos de degradação utilizando-se o banco de dados do Departamento de Transporte de Nevada (NDOT), obtido durante um ano de estágio desenvolvido na Universidade de Nevada, Las Vegas (USA). Foi realizado um estudo comparativo dos modelos de degradação, e após a calibragem dos modelos de previsão com o banco de dados de NDOT, foi determinado o modelo de degradação mais apropriado para as OAEs sob responsabilidade do DNIT e banco de dados similares, visando proporcionar apoio na tomada de decisões e garantir um desempenho eficiente das estruturas. Foi determinado que a Regressão de Potência é o método de cálculo mais apropriado para a estimação das curvas de degradação das OAEs no Brasil, sob responsabilidade do DNIT. Podendo-se utilizar esta regressão de maneira individual para cada uma das OAEs, uma vez sejam realizadas mais inspeções nas estruturas.
The objective of this research was to propose a degradation prediction model, based on a deterministic and stochastic analysis, to contribute to the accompaniment of the Brazil Bridges, under the responsibility of the National Department of Transport Infrastructure - DNIT, and other similar databases. In the DNIT database there is an inventory of four thousand five hundred and thirty-one bridges, but only one inspection was carried out between 2012 and 2016. Due to the insufficient number of historical records for the development of a model for predicting the degradation of bridges, the models of degradation were tested using the database of the Department of Transportation of Nevada (NDOT), obtained during a year of internship developed at the University of Nevada, Las Vegas (USA). A comparative study of the degradation models was carried out, and after the calibration of the forecast models with the NDOT database, the most appropriate degradation model was determined for the bridges under the responsibility of DNIT and similar databases, aiming to provide support in decision-making and ensure efficient performance of structures. It was determined that the Power Regression is the most appropriate calculation method for the estimation of the degradation curves of OAEs in Brazil, under the responsibility of DNIT. This regression can be used individually for each of the OAEs, once more inspections are performed on the structures.

Resumo: A Iniciativa Open Archives (OAI) permite que bibliotecas e museus criem e compartilhem suas próprias Bibliotecas Digitais (BD) com baixo custo. A concepção de BDs OAI ´e baseada no protocolo OAI-PMH, que, embora tenha se consolidado como padrão para disseminação de metadados, não se preocupa com aspectos relativos à preservação digital e disponibilidade dos objetos, requisitos essenciais neste tipo de sistema. Assim, a construção de mecanismos que garantam melhorias neste âmbito, sem acréscimos de custo, torna-se um grande desafio. Devido suas estruturas topológicas, redes Peer-to-Peer são candidatas naturais para resolver este tipo de problema. Esta dissertação apresenta uma arquitetura OAI para preservação digital baseada em redes P2P estruturadas (Tabelas Hash Distribuídas). A proposta da arquitetura é manter as características atuais do protocolo OAI-PMH e realizar, de forma transparente ao usuário, a preservação do conteúdo, considerando a importância do objeto para o administrador. A arquitetura proposta, bem como seus componentes e trocas de mensagens foram validadas através da execução de experimentos e da implementação de protótipos não funcionais.

Full text
Abstract:
Les savoirs traditionnels médicinaux c’est-à-dire l’aspect de la médecine traditionnelle portant sur des connaissances relatives au médicament traditionnel à base de plantes, qui part de la collecte des végétaux jusqu’au produit final, constituent un élément important dans la réalisation de la couverture des besoins de santé publique. En Afrique, les savoirs traditionnels médicinaux contribuent selon l’Organisation mondiale de la santé (OMS) à hauteur de 80% des besoins de santé des populations. Les savoirs traditionnels médicinaux représentent une source d’informations notamment dans la perspective d’une éradication des maladies endémiques du continent africain. L’OMS, et l’Union africaine (UA) voient dans les savoirs traditionnels médicinaux une piste de recherche en vue du développement de nouveaux médicaments à des prix abordables. Leur importance est aussi constatée au niveau de l’industrie du médicament où ils représentent 30% de la recherche dans l’industrie pharmaceutique et l’essentiel des informations dans le secteur des phytomédicaments. Cette appétence pour les savoirs traditionnels médicinaux ainsi que la médiatisation des actes de biopiraterie, ont contribué à renforcer leur valeur (sur les plans scientifique, économique, social et politique) et à justifier la nécessité de les protéger. Cependant, contrairement à la tendance actuelle des pays africains, l’Organisation africaine de la propriété intellectuelle (OAPI), à travers son Accord de Bangui révisé, ne dispose pas de mécanismes de propriété intellectuelle permettant une protection satisfaisante des droits des détenteurs de savoirs traditionnels médicinaux (tradipraticiens, familles, communautés autochtones et locales). Face à ce qui s’apparente à un vide juridique, il convient de s’interroger sur le régime juridique à mettre en place. Autrement dit, quel système sui generis de protection des savoirs traditionnels médicinaux faut-il envisager pour les pays membres de l’OAPI? C’est à cette interrogation que la présente étude se propose d’apporter des éléments de réponses. L’objectif visé sera de démontrer, dans le cadre d’une démarche prospective prenant appui notamment sur les droits de l’homme, le droit international de la propriété intellectuelle, le droit civil, le droit de la biodiversité, et les lois nationales, en particulier, celles de la République du Congo (Brazzaville), qu’il est possible d’établir au sein de l’OAPI un régime juridique cohérent et adapté à même de répondre aux besoins et attentes des différents acteurs intervenant dans l’exploitation de ces créations intellectuelles
Traditional medical knowledge, which is the aspect of traditional medicine relating to the knowledge of plant-based therapy and which goes from collecting plants to issuing a finished product, is a key component for providing health care coverage for all. According to the World Health Organization (WHO), traditional medical knowledge contributes about 80% of primary health care in Africa. Traditional medical knowledge is perceived as a valuable source of information useful to eradicate African endemic diseases. The WHO and the African Union (AU) consider that traditional medical knowledge is a serious way for researchers to develop new and affordable drugs. Traditional medicinal knowledge is also important for the drug industry where it represents 30% of the researches made in the pharmaceutical sector and constitutes the main source of information in the herbal medicine sector. The drug industry’s increasing interest for traditional medical and the huge media coverage for biopiracy cases strengthened the (scientific, economic, social and politic) value of traditional medicinal knowledge and contribute to justify their protection. However contrary to the current trend in many African countries, it appears that the African Intellectual Property Organization (OAPI) and the Bangui Agreement, does not provide any suitable legal protective mechanism for the intellectual property rights of the holders of traditional medical knowledge (traditional healers, families, indigenous and local communities).In view of the limits and weaknesses of the intellectual property mechanisms to provide an effective protection to traditional medicinal knowledge’s holders, it is quite legitimate to question the legal mechanism or system to implement. In other words, what type of sui generis protection OAPI members can enact to protect traditional medicinal knowledge? This is the question that the present study intends to answer. The aim is to demonstrate from a prospective approach with regards to human rights, international intellectual property law, civil law, biodiversity law, and national laws, in particular the ones of the Republic of Congo (Brazzaville), that it is possible to build a coherent and adapted legal regime

Abstract:
Par rapport aux nombreux signes d'artisans identifiés autrefois sur les objets et les corps humains, ces marques de l'Organisation Africaine de la Propriété Intellectuelle (l'OAPI), véritables instruments de conquête de la clientèle, sont définies comme des signes visibles servant à distinguer les produits et services d'une personne physique ou morale, de ceux des concurrents, par l'annexe III de l'Accord de Bangui révisé le 24 février 1999, en vigueur le 28 mars 2002. . Parmi les divers titres délivrés dans ce système africain autrefois francophone, à législation uniforme, pour les seize États membres, les marques, semblent réduites aux fonctions symboliques et uniquement conçues pour les pays développés dans certaines mentalités africaines. Certes, la protection des signes par un droit écrit est assez récente car née avec l'industrialisation en Europe. Mais, qu'en est-il réellement des marques de produits ou de services puisque les sociétés africaines en profondes mutations, vivent une économie de marché qui ne peut se développer, créer des richesses nationales et des emplois que si les agents économiques confrontent leurs aptitudes sur les marchés ? Il suffit de voir l'usage des marques dans les sociétés africaines et leur installation progressive dans toutes les couches sociales. Les consommateurs potentiels devraient être plus sensibilisés dans un langage adapté au leur. Moyen qui semble efficace pour mieux faire respecter les marques, l'escortant de sanctions effectives contre les atteintes. Inutile de multiplier donc les réformes législatives. Cette thèse vise donc à répondre aux questions de savoir si la protection des droits exclusifs des titulaires en conflit apparent avec les intérêts communautaires des tiers, peut être parmi les facteurs socioéconomiques et industriels en faveur du développement de l'Afrique ?

Abstract:
Background. A multitude of data exists regarding global incidence of OASI as well as its contributing factors and complications. Little to no data exists regarding the incidence of OASI or its complications and the nature of these complications within South Africa. Objective. To describe the rate and nature of complications of OASI that occur within 6 weeks following primary repair of an OASI, followed up at the GSH perineal clinic. Secondarily, to investigate the incidence of OASI and follow up rate post primary repair Methods. This was a retrospective chart review. Participants were identified from theatre record books between January 2014 and December 2015. The charts of those that attended the perineal clinic follow up were reviewed and complications and possible associated risk factors were identified from the clinical notes. Primary aims were to identify the incidence and nature of complications seen in this population as well as possible related risk factors. The secondary aims were to determine the incidence of OASI and follow up rate for complication following primary OASI repair. Results. The mean age of participants was 25.85 years with a mean body mass index of 25.15kg/m2 . The mean birthweight seen was 3382.05 grams. Constipation (10.87%), pain with defaecation (11.96%) and anal incontinence (10.87%) were the most frequently reported complications. Wound infection was found on examination in 3.26% of participants and wound dehiscence was seen in 6.67%. Incidence of OASI in this study group was 8.64 per 1000 vaginal deliveries. The follow up rate of these participants was 26.20%. A total of 374 OASI were repaired within this region during the study period. Only 97 of these attended follow up, for which 93 folders were available to be included in analysis Conclusion. The Incidence of OASI in this Western Cape region is within the range seen worldwide but the proportion of complications seem to be less than global data suggests despite adverse conditions, theatre delays and the fact that repairs were mostly performed by specialists in training. It was not possible to identify any relationship with possible associated factors. There is a very poor follow up rate within this community which needs to be explored and systems need to be put in place to ensure all participants are given the opportunity of follow up.

Abstract:
The growth of Web technologies has benefited researchers and the academic community by supporting the access of electronic publications as soon as they have been finished and published. In this context, Digital Libraries emerges as complex information systems which are essential for disseminating and preserving data, information and knowledge. However, due to the high amount of content available on the Web, specially in Digital Libraries, users face many correlated options, what result in the phenomenon known as information overload. Aiming to decrease or even eliminate these diffculties, recommender systems for Digital Libraries have been proposed and developed. This work presents a personalized recommender system which presents alternative ways to achieve better query results. For this, the main existing approaches of automatic recommendation have been studied in order to identify extension points and points to be improved. The proposed recommender system follows a hybrid approach which combines filtering techniques, content-based recommendation and collaborative recommendation. A hybrid recommendation engine has been proposed, which uses standard technologies for content description (Dublin Core), for communication with Digital Libraries (OAI-PMH Protocol ), as well as the user profile extracted from the curriculum vitae Lattes. The proposed solution has been evaluated in the context of the CiteSeer database, which contains papers and articles in the Dublin Core format. The preliminary results has showed an improvement in the quality of recommendation, thus presenting a better precision and coverage, when compared with existing approaches based either on content-based recommendation or on collaborative recommendation
O crescimento acelerado das tecnologias Web tem beneficiado pesquisadores e acadêmicos, pois as publicações de pesquisa podem ser acessadas eletronicamente tão logo elas tenham sido finalizadas e publicadas. Nesse contexto, surgem as Bibliotecas Digitais como um sistema de informação complexo que possui uma série de atividades que integram coleções, serviços e pessoas em suporte ao completo ciclo de criação, disseminação, acesso e preservação de dados, informação e conhecimento. No entanto, devido a enorme quantidade de conteúdo presente na Web, em particular nas Bibliotecas Digitais, usuários acabam se deparando com uma diversidade muito grande de opções, o que leva ao fenômeno conhecido como sobrecarga de informação. Com o objetivo de contribuir para amenizar ou até mesmo eliminar essas dificuldades, sistemas de recomendação para Bibliotecas Digitais têm sido propostos e desenvolvidos. Este trabalho segue essa direção, investigando soluções alternativas para alcançar mais qualidade nas indicações geradas por um sistema de recomendação na sua tarefa de ajudar os seus usuários. Para isso estudou-se as abordagens tratadas na literatura especializada sobre tais sistemas, propondo-se em seguida, um sistema de recomendação personalizada de artigos científicos para Bibliotecas Digitais. Tal sistema seguiu uma abordagem híbrida, procurando tirar proveito das características interessantes identificadas nas técnicas de filtragem e recomendação baseadas em conteúdo e colaborativa. Nesse sentido desenvolveu-se um engenho de recomendação híbrido que se utiliza de tecnologias padrão para a descrição de conteúdo (Padrão Dublin Core), comunicação com Bibliotecas Digitais (Protocolo OAI-PMH) e perfil do pesquisador (Currículo Lattes). Finalmente, avaliou-se o sistema proposto sobre uma base de dados do CiteSeer contendo artigos no formato Dublin Core, tendo os resultados preliminares mostrado-se satisfatórios melhorando a precisão na recomendação e a cobertura quando comparado com sistemas que implementam abordagens baseada em conteúdo e colaborativa isoladamente

Full text
Abstract:
Les présomptions interviennent pour corriger les lacunes du raisonnement juridique. Elles sont traditionnellement définies comme « des conséquences que la loi ou le magistrat tire d’un fait connu à un fait inconnu ». Les présomptions occupent un rôle important en droit de la propriété intellectuelle car la recherche de la vérité ainsi que le traitement du doute en constituent l’essence. Qu’il s’agisse d’appréhender les objets (œuvre de l’esprit, invention, marque, etc.), de désigner les acteurs (titulaires ou contrefacteurs) ou de délimiter le contenu des droits de propriété intellectuelle, l’usage des présomptions est incontournable. Cependant, les nouveaux défis (numérique, mondialisation de l’économie, communautarisation du droit, etc.) auxquels sont confrontées les créations immatérielles conduisent le législateur et le juge à galvauder les présomptions. On assiste à une inflation voire une densification de la « norme présomptive » en droit de la propriété intellectuelle : il y a une présomption pour presque tout, sur presque tout et presque partout. Cela fragilise le système de protection des créations immatérielles et, fatalement, engendre une insécurité juridique en droit de la propriété intellectuelle. L’objectif de notre thèse est d’analyser ce que recouvre réellement l’idée de présomptions en droit de la propriété intellectuelle et de délimiter concrètement leur champ d’action (première partie). Cette démarche envisage à terme de proposer une théorie générale des présomptions à partir de laquelle les présomptions applicables en propriété intellectuelle pourraient s’identifier et tirer leur légitimité (deuxième partie). Une telle approche permettra de fournir une grille de lecture plus pertinente tant aux théoriciens qu’aux praticiens de la matière pour aborder efficacement les problématiques inhérentes à ce domaine dont la complexité n’est plus à présenter
Presumptions in intellectual property law, analysis in the light of general lawPresumptions intervene to correct shortcomings in legal reasoning. They are traditionally defined as "consequences that the law or the magistrate draws from a known fact to an unknown fact". Presumptions play an important role in intellectual property law because the search for truth and the treatment of doubt are its essence. Whether it is to apprehend the objects (intellectual work, invention, trademark, etc.), to designate the actors (owners or counterfeiters) or to delimit the content of the intellectual property rights, the use of presumptions is unavoidable. However, the new challenges (digital, globalization of the economy, communalization of the law, etc.) faced by intangible creations force the legislator and the judge to squander the presumptions. We are witnessing inflation and even densification of the "presumptive norm" in intellectual property law: there is a presumption for almost everything, on almost everything and almost everywhere. This weakens the system of protection of intangible creations and, inevitably, creates unprecedented legal uncertainty in intellectual property law. The aim of our thesis is to analyze what the idea of presumptions in intellectual property law really covers and to concretely define their field of action. This approach ultimately aims to propose a general theory of presumptions from which the presumptions applicable in intellectual property could identify and draw their legitimacy. Such an approach that will provide a reading grid more relevant to both theorists and practitioners of the subject to effectively address the issues inherent in this area whose complexity is more to present

Abstract:
Ce travail se propose de répertorier les incidences de l'Accord sur les ADPIC sur la protection de la propriété industrielle de seize Etats africains, signataires de l'Accord instituant l'OMC et réunis au sein de l'Organisation africaine de la propriété intellectuelle (OAPI). En raison de l'exigence de conformité de leur législation à l'Accord ADPIC, ces pays ont du procéder à la révision en profondeur de l'Accord de Bangui du 2 mars 1977, portant création de l'OAPI. Ce texte qui constitue le Code de propriété intellectuelle desdits Etats a subi d'importantes modifications du fait de cette révision. Les incidences de l'Accord ADPIC au sein de l'OAPI s'étendent aussi à l'ordre juridique interne de ces Etats, notamment sur leurs institutions et leurs pratiques administratives et judiciaires. En outre, l'Accord ADPIC, du moins certaines de ses dispositions, objets d'une forte contestation dans les pays en développement confrontés à d'importants problèmes sociaux, est de plus en plus décrié par les populations et les gouvernements de ces Etats. Les revendications qu'ils ont formulées à cet égard ont abouti à la Déclaration de Doha (Qatar) sur l'Accord ADPIC et sur la santé publique en novembre 2001. Le contenu de cette Déclaration et les décisions qu'elle a ultérieurement entraînées devraient avoir pour conséquence, une renégociation de l'Accord de Bangui révisé ou l'adoption de mesures internes par les Etats membres
The aim of this report is to list the implications of the TRIPS Agreement for the protection of industrial property in sixteen African states, parties to the Agreement establishing the WTO and members of the African intellectual protection organization (OAPI). Due to the requirements of conforming their legislation to the TRIPS Agreement, these countries have had to carry out an in-depth revision of the Bangui Agreement of 2 March 1977, relating to the creation of OAPI. This text, the Code on intellectual property of the above States, has undergone significant changes due to this revision. The effect of the TRIPS Agreement on OAPI has also changed the internal legal structure of these states, particularly their institutions and their administrative and legal practices. Moreover, some of the dispositions of the TRIPS Agreement, strongly contested by developing countries with considerable social problems, are facing increasingly hostile reactions from the populations and governments of the States. The requested demands in this respect by theses last have led to the Doha Declaration (Qatar) on the TRIPS Agreement in its relations on public health, of November 2001. The contents of this Declaration and the decisions which it brought about may lead to a renegotiation of the revised Bangui Agreement or the adoption of internal measures by Member states

Abstract:
La procedure de controle instituee par l'accord de bangui, ratifie le 8 fevrier 1982, est une necessite juridique en reponse a un imperatif economique: le developpement par l'acquisition et le deploiement des techniques rentables. La premiere partie de la these opere une description comparative du cadre du controle et effectue une analyse du fonctionnement de ladite institution. Elle met en evidence les attributions de l'autorite du controle : les attributions strictu senso procedent des dispositions regionales: les pouvoirs de l'autorite de controle consistent a interdire les clauses limitatives (abusives) figurant dans le contrat de licence. Les attributions lato senso sont deduites des positions doctrinales: les competences de l'autorite de controle s'elargissent jusqu'a empieter sur celles du juge en matiere de litige concernant les actes juridiques. Elles permettent d'assurer a la procedure de controle efficacite et efficience. La deuxieme partie scrute les retombees de la procedure du controle sur l'environnement des techniques. Sur le plan juridique, la menace de nullite, efficace pour decourager les tentatives d'insertion de clauses abusives, mais insuffisante pour encourager la signature des contrats de licence, est secondee par les garanties supplementaires exigibles tant au concedant qu'au concessionnaire afin de stimuler la conclusion de la licence. Sur le plan economique, le controle contribue a la mise en place d'une industrie consequente. Il favorise le passage de la simple reproduction de techniques a leur determination celle-ci implique non seulement le developpement des capacites techniques mais aussi la mutation de l'environnement economique, la mise en valeur des ressources et techniques locales
The control procedure laid down by the bangui agreement and ratified on february 8, 1982, is a judicial necessity in response to an economic imperative : development by the acquisition and the deployment of profitable technology. The first part of the thesis makes a comparative description of framework of control and carries out an analysis of the functioning of the said institution. It brings into focus the prerogatives of the control authority: the prerogatives stricto senso proceed from regional arrangements: the powers of the control authority consist in forbidding the limiting clauses (excessives) appearing in the licence contract. The prerogatives lato senso, are deduced from doctrinal positions: the juridictions of the control authority extend to the point of encroachingupon those of the judge in matters of litigation concerning writs. They ensure the efficiency and the effectiveness of the control procedure. The second part scrutinizes the repercussions of the control procedure on the technological environment. At the judicial level, the threat of nullity, which is effective for discouraging the attempts at the insertion of excessive clauses, but inadequate for encouraging the signing of licence contracts, is supported by supplementary guarantees exactable as much from the grantor as from the licensee, in order to stimulate the conclusion of the licence. At the economic level, the control contributes to the setting up of an important industry. It favours the passage from the simple reproduction of technologies to their determination. This implies not only the development of technological capacities but also the alteration of the economic environment, the development of local resources and of local technologies

Federated, distributed, and broadcast searches on the Internet depend on an underlying common metadata framework by which the information resources to be searched are organized. The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is designed to facilitate searches across OAI-compliant databases. Software such as Arc allow service providers to offer federated searching of multiple, OAI-compliant resources. The majority of web-accessible information resources, however, are not OAI-compliant. This article describes a process whereby readily available open source tools and customized scripts were developed for integrating metadata from non-OAI compliant repositories for a federated search. The work described is being carried out as part of the development of the Digital Library of Information Science and Technology (DLIST), an Eprints repository.

Information about a particular subject can be stored in different repositories such as databases, digital libraries, spreadsheets, text files, web pages etc. In this context of heterogeneous data sources, to query, possibly in natural language, to integrate information and to promote interoperability are tasks that depend, among other factors, on the prior knowledge that an user has regarding location, owner, content description of each information source etc. More specifically, in the case of database, this information are not usually stored in a catalogue of the database management system and to obtain is necessary to resort to the administrator s knowledge database. Another factor is the absence of search engines to databases in the web that access and make available the information in those repositories, data are limited due to the organizations themselves. In a shared information environment, it is highly relevant to make possible access to metadata that describe a data source, regardlessly of the device and format in which is stored. This study aims to describe a mechanism to promote interoperability of relational databases with other sources of information through the extraction and exposing of metadata using OAI-PMH
Informações sobre um determinado assunto podem estar armazenadas em diferentes repositórios como banco de dados, bibliotecas digitais, planilhas eletrônicas, arquivos textos, páginas na web etc. Nesse contexto de fontes de dados heterogêneas, consultar, possivelmente em linguagem natural, integrar informações e promover interoperabilidade são tarefas que dependem, dentre outros fatores, do conhecimento prévio que um usuário tem sobre a localização, o proprietário, a descrição do conteúdo de cada fonte de informação. Mais especificamente, no caso de bancos de dados, essas informações não são, em geral, armazenadas no catálogo de um sistema gerenciador de bancos de dados; para obtê-las é necessário recorrer ao conhecimento do administrador desse banco. Outro fator que evidencia essa dependência é a ausência de mecanismos de busca a bancos de dados na web que acessam e tornam disponíveis as informações contidas nesses repositórios, devido ao fato desses dados estarem limitados às próprias organizações. Em um ambiente de compartilhamento de informações, é altamente relevante tornar possível o acesso aos metadados que descrevem uma fonte de dados, independentemente do meio e do formato em que esteja armazenada. Este trabalho tem como objetivo descrever um mecanismo para promover interoperabilidade de bancos de dados relacionais com outras fontes de informações, por meio da extração e exposição dos metadados usando o protocolo OAI-PMH.

Researchers are changing old habits and making self-publishing in open access archives through the Internet, allowing the creation of hypermedia documents and streamlining communication. To keep track of these repositories and open meet this new demand came the Open Archives Initiative (OAI Open Archives Initiative), trying to make possible the interoperability of repositories to define the initiative Protocol for Metadata Harvesting of the Open Archives Initiative (OAI-PMH Open Archives Initiative Protocol for Metadata Harvesting) which is a protocol used to distribute and collect metadata, following the pattern Dublin Core (DC), at least. Through the collective characteristic of scientific finds, a researcher without partners hardly gets significant results and this publication is a mechanism that allows the creation of links in the community. Social Networks on the Internet are relations between individuals in computer mediated communication, seeking to connect people and provide communication. This paper presents the UbiProject, an environment which allows the formation of a social network of researchers on the Internet, which will include a repository for scientific projects joined to digital resources in form of text files, pictures, videos or hyperlinks. Both projects and resources will be compatible with OAI-PMH as the environment implements the Dublin Core metadata pattern in the repository, which will be able to be propagated on the Internet, working as a way of open digital publication tool, based on the self-archiving of the member s production.
Os pesquisadores estão modificando antigos hábitos e fazendo a autopublicação em repositórios de acesso aberto, através da Internet, permitindo o surgimento de documentos hipermídia e dinamizando a comunicação. Para manter o controle desses repositórios abertos e atender a esta nova demanda surgiu a Iniciativa de Arquivos Abertos (OAI Open Archives Initiative). Buscando viabilizar a interoperabilidade de repositórios, a iniciativa definiu o Protocolo para Colheita de Metadados da Iniciativa de Arquivos Abertos (OAI-PMH Open Archives Initiative Protocol for Metadata Harvesting) que é um protocolo utilizado para coletar e distribuir metadados que seguem no mínimo o padrão Dublin Core (DC). Pela característica coletiva do descobrimento científico, um pesquisador sem parceiros dificilmente obtém resultados significativos e a publicação de suas produções é um mecanismo que permite a criação de elos na comunidade científica. As Redes Sociais na Internet permitem o constante relacionamento entre indivíduos através de contato e comunicação mediada por computador, buscando conectar pessoas e proporcionar o diálogo. Este trabalho apresenta o UbiProject, uma infra-estrutura para a formação de uma Rede Social de pesquisadores na Internet, que traz um repositório de projetos científicos associados a recursos digitais na forma de arquivos de texto, fotos, vídeos ou hiperlinks. Projetos e recursos serão disseminados devido à compatibilidade com o padrão de metadados DC e OAI-PMH. O ambiente computacional serve então como uma forma de publicação científica digital aberta, baseado no auto-arquivamento da produção dos membros.

Abstract:
Achieving interoperability between digital libraries and visualization tools is a difficult problem. To solve this problem, a version of the Open Archives Initiative (OAI) Protocol for Metadata Harvesting called VIDI is proposed. It is a lightweight protocol, which contains only 5 request verbs -- Identify, ListMetadataFormats, ListVisdataFormats, ListTransformers, and RequestResultSet. It is extended from the OAI protocol, which enables its simplicity and wider acceptability. It is flexible, which avoids a rigid architecture in implementation. It is general, so it can apply to all kinds of Visualization Systems and Digital Libraries. But most importantly, it reaches our goal of enabling operability between Visualization Systems and Digital Libraries. The protocol design and implementation details are given. Two prototype systems are implemented to demonstrate the above features. Implementation details are given about ENVISION-ODL and ENVISION-MARIAN. Analysis, evaluation, and conclusions reinforce the discussion of the benefits of VIDI.

Abstract:
A Digital Library (DL) is an electronic information storage system focused on meeting the information seeking needs of its constituents.

As modern DLs often stay in synchronization with the latest progress of technologies in all fields, interoperability among DLs is often hard to achieve. With the advent of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and Open Digital Libraries (ODL), lightweight protocols show a promising future in promoting DL interoperability. Furthermore, DL is envisaged as a network of independent components working collaboratively through simple standardized protocols. Prior work with ODL shows the feasibility of building componentized DLs with techniques that are a precursor to web services designs.

In our study, we elaborate the feasibility to apply web services to DL design. DL services are modeled as a set of web services offering information dissemination through the Simple Object Access Protocol (SOAP). Additionally, a flexible DL user interface assembly framework is offered in order to build DLs with customizations and personalizations. Our hypothesis is proven and demonstrated in the PhysNet reengineering project.

Full text
Abstract:

Rapid changes in Earth?s marine environment are sufficiently rare that the scope and consequences of these events cannot be inventoried without recourse to the stratigraphic record of deep pre-historic time. Traditional stratigraphy divides geologic time into a succession of coarse biozones ? uneven time bins, each recognized by distinctive index fossils and spanning several hundred thousand to even a few million years. This thesis uses the CONOP software to resolve sequences of global appearance and disappearance events at the species level across the late Cenomanian oceanic anoxic event (OAE 2) at a much finer resolution than traditional biostratigraphy. The resulting time-lines include information for the Aptian to Maastrichtian from 501 locations, 4,962 taxa, and 25,112 local last occurrences. This dataset is large enough to represent the global environment and to compensate for the inevitably patchy and incomplete record preserved at any one location. Six geographically widespread clades ? ammonites, calcareous nannofossils, dinocysts, benthic forams, planktonic forams, and radiolaria ? were analyzed; they span a range of trophic levels, composition and preferred habitat. Extinction pulses and intervals of falling diversity are not unique to OAE 2 or even uniquely severe. Several occur throughout the Albian-Santonian interval. The key is to monitor trends in diversification rate. OAE 2 is distinguished as a boundary between more positive (or equal in the ammonite case) and more negative diversification regimes. It may have been part of a general habitat deterioration or disturbance, but it would be too simplistic to describe it as a coordinated pelagic extinction event.

Abstract:

Barn med Down syndrom har ofta återkommande hörselproblem som exempelvis vaxpropp och sekretorisk mediaotit. Vanligt förekommande hörselnedsättning bland dessa barn är en fluktuerande konduktiv hörselnedsättning. Den utvecklingsstörning som syndromet orsakar kan leda till att barnen ej kan medverka aktivt vid konventionella hörselmätningar. Metoder för hörselutredning av små barn och barn som ej kan medverka adekvat är BRA, OAE och tympanometri. Syftet med arbetet är att belysa resultaten från BRA, OAE och tympanometri hos barn med DS. Vidare syftar studien till att belysa tänkbara habiliterande insatser för att bibehålla eller förbättra hörseln hos barn med Down syndrom. Som metod används systematisk litteraturstudie. Resultatet från föreliggande studie visar att mätresultat skiljer sig mellan barn med Down syndrom och barn utan Down syndrom. Strukturella avvikelser i hörselsystemet hos barn med Down syndrom påverkar resultaten från dessa mätningar. Det är därför av vikt att resultaten tolkas utifrån kunskaper om hur olika faktorer i hörselsystemet orsakade av syndromet kan påverka resultaten. Barn med DS behöver regelbundna och återkommande hörselhabiliterande insatser för att förebygga konduktiva hörselnedsättningar.

Abstract:
Le passage Cénomanien-Turonien (~94 Ma) au Crétacé supérieur est marqué par une période de diminution de la quantité d’O2 dans les sédiments et la colonne d’eau et de perturbations biogéochimiques appelé Évènement Océanique Anoxique 2 (OAE 2). Comme l’ensemble des OAEs du Crétacé, l’OAE 2 s’est mis en place dans un contexte d’augmentation de la concentration en CO2 dans les océans et l’atmosphère, interprétée comme d’origine volcanique. L’hétérogénéité des réponses à cette perturbation globale suggère que des paramètres environnementaux régionaux ou locaux ont contribué au scénario de mise en place et d’évolution de l’OAE 2. L’objectif cette thèse est ainsi de déterminer le rôle de ces mécanismes à différentes échelles spatiales. La démarche consiste en une comparaison des conditions biogéochimiques associées à l’OAE 2 dans un bassin épicontinental, comme le Bassin Vocontien (SE France), avec les bassins océaniques mondiaux. La comparaison de données de géochimie organique (TOC, HI vs. OI), inorganique (enrichissements en éléments majeurs et traces, spéciation du fer) et isotopique (δ13C, δ15N, δ34S) de deux coupes du Bassin Vocontien semble indiquer que l’augmentation de la quantité de CO2 et de sulfates dans le bassin, associée à l’activité d’une Grande Province Volcanique, fut le facteur déclencheur de l’OAE 2. Par ailleurs, les hétérogénéités des conditions d’oxygénation semblent être majoritairement associées aux configurations géométriques des bassins et au taux de renouvellement des leurs eaux profondes, mais aussi aux conditions de productivité primaire influencés par les cycles de nutriments, et enfin aux paramètres climatiques régionaux
The Cenomanian-Turonian transition (~94 Ma) of the upper Cretaceous is marked by a period of decreased O2 concentration in the sediments and water-column and biogeochemical perturbations, named Oceanic Anoxic Event 2 (OAE 2). Like all the OAEs of the Cretaceous, OAE 2 was initiated in a context of increasing CO2 concentrations in the oceans and in the atmosphere, interpreted as volcanic outgassing. The heterogeneity in the responses toward this global-scale perturbation suggests that regional or local environmental mechanisms contributed to the scenario of initiation and evolution of OAE 2. The objective of this thesis is to determine the role of these mechanisms at different spatial scales. The approach consists in a comparison of the biogeochemical conditions associated with OAE 2 in an epicontinental basin, as the Vocontian Basin (SE France), with others basins in the world. The comparison of geochemical organic (TOC, HI vs. OI), inorganic (Major and Trace elements enrichments, iron speciation) and isotopic (δ13C, δ15N, δ34S) data of two sections from the Vocontian Basin likely indicate that the concentration of CO2 and sulfates in the basin, associated with the activity of a Large Igneous Province, was the triggering factor of the OAE 2. Heterogeneities in the oxygenation conditions were predominantly associated with basin configuration and renewal rate of deep waters, but also with primary productivity conditions and with regional climatic parameters

Abstract:
The discovery of otoacoustic emissions (OAE) has advanced our understanding of cochlear mechanics and the efferent auditory system. OAE are sounds generated within normal cochlea either spontaneously or in response to stimulation. The ability to measure OAE non-invasively, objectively and quickly makes a powerful tool to probe cochlear mechanics. Stimulation of the efferent auditory system causes changes in cochlear amplification processes and hence changes characteristics of OAE. Contralateral acoustic stimulation, commonly called OAE suppression, provides an index of the efferent auditory system (specifically, medial olivocochlear bundle) functioning. OAE is also a sensitive tool to demonstrate subtle changes in cochlear functioning caused by various pathological (e.g., noise exposure, aspirin toxicity, etc.) and non-pathological (e.g.,posture, efferent stimulation) factors. Although OAE are frequently used in both clinic and laboratory, their generation mechanism was not clearly understood until recently. It is currently accepted that distortion product otoacoustic emissions (DPOAE) are composed of two separate components, named wave- and place-fixed emissions. They not only arise from two different cochlear locations but also from two fundamentally different processes. Wave-fixed components arise from distortion sources and manifest a phase that is almost independent of frequency, where as, place-fixed components arise from reflection sources and have a phase that increases systematically with frequency. The overall aim of the work presented in this thesis was to use various OAE methods to examine cochlear function and the efferent auditory system. A related objective was to substantiate the functional relevance of the efferent auditory system in speech-in-noise perception, in order to address the clinical significance of measuring OAE suppression. Cochlear functioning was potentially manipulated by three treatments separately: one extrinsic (electromagnetic radiation exposure from mobile phone) and two intrinsic (posture and efferent activation). Potential changes in auditory function due to mobile phone exposure were evaluated in a within-subject study in a double-blind design (n=35).A comprehensive examination of the auditory system was conducted using audiometry,OAE and auditory event related potentials (ERP). The second experiment used mechanism-based DPOAE to investigate posture-induced changes in cochlear functioning (n=15). Similar DPOAE measurements were performed to evaluate the effect of contralateral acoustic stimulation on cochlear functioning (n=14). The last experiment examined the relationship between contralateral suppression of transient evoked otoacoustic emissions (TEOAE) and recognition of speech in noise (n=13). Results indicate that (i) acute exposure to mobile phone radiation does not cause any significant changes in auditory functions measured by TEOAE suppression, DPOAE or ERP (however, there were changes in auditory thresholds at 6 and 8 kHz), (ii) posture induced cochlear changes and contralateral acoustic stimulation cause significantly greater reduction in place-fixed components than wave-fixed components, and (iii) the efferent auditory system plays an anti-masking role in speech-in-noise recognition. It appears that wave- and place-fixed components are differentiallysensitive to changes in cochlear functioning. Collectively, the present results provide emerging empirical support for the need to separate the wave- and place-fixed components in DPOAE measurements. Because of inherent differences in the generation of wave- and place-fixed components, it is suggested that the separation of the components may improve the efficiency of DPOAE-based measures of cochlear dysfunction and also, of the efferent auditory system function.

Abstract:
Populationer med utvecklingsstörning behöver kontinuerlig hörseltestning, men konsensus om lämplig testmetod saknas. Syfte: Syftet med Studie I var att utvärdera psykoakustisk testmetod och med Studie II att utvärdera OAE-registrering som komplementär metod. Studie I. 1478 barn och vuxna med lätt till djup utvecklingsstörning, i åldrarna 7-91 år deltog i studien. De testades med tonaudiometri på sex frekvenser på screeningnivån 20 dB HL med lätt modifierad testutrustning. Kriterierna för remittering var tröskelnivåer på ≥ 25 dB HL på två frekvenser eller flera på ett öra eller båda. 1470 (99,5%) barn och vuxna medverkade i screeningen och 1325 (90%) testades på båda öronen på samtliga sex frekvenser. En majoritet, 987 (67,1%), medverkade i vanlig tonaudiometri, 234 (15,9%) i lekaudiometri, och 249 (16,9%) testades med observationsaudiometri. 669 (45%) visade normala värden medan 809 (55%) visade onormala värden relaterat till screeningkriterierna. Av de 809 accepterade 441 (54,5%) remittering för hörselutredning. Studie II. 38 vuxna med måttlig till djup utvecklingsstörning, i åldrarna 31-73 år deltog i studien, alla med ofullständiga testresultat vid tonaudiometri. Portabel utrustning, ILO 288 Echoport och dator Compaq LTE 5100 med mjukvara ILO 88 V 4.2, användes. Otoskopi och tympanometri kompletterade registreringen. Kriterierna för emissioner var S/N 3 dB eller mer och reproducerbarhet på 60% eller mer på åtminstone tre frekvensband. Kriterierna för partiella emissioner var desamma men för en eller två frekvenser. Två personer behövdes för att genomföra testningen: en för att hålla testpersonen lugn och tyst och den andra för att sköta testapparaturen. Reproducerbara TEOAE-svar registrerades från 11 öron (7 personer), partiella svar från 6 öron (4 personer), inga emissioner kunde registreras från 15 öron (10 personer) och 4 öron (4 personer) med otit eller vaxpropp testades inte. Registreringen från 24 öron (13 personer) kunde inte värderas p g a alltför mycket yttre och inre störningar. 8 personer vägrade delta i testningen. Endast 4 personer visade emissioner på båda öronen. Resultatet av undersökningen blev att 34 personer (89.5%) behövde testas om eller bli remitterade för ytterligare utredning, 21 av dem (55%) beroende på störningar vid registreringen eller p g a vägran att medverka. Konklusion: Tonaudiometri med lätt modifiering kan användas för screening av en population med lätt till djup utvecklingsstörning. TEOAE-registrering, som den genomfördes, kan inte uppfylla kraven på en fungerande testmetod för en population med måttlig till djup utvecklingsstörning. I det enskilda fallet kan TEOAE-registrering vara ett komplement till andra hörseltest. Det mest utmanande och tidskrävande är att introducera testprocedurerna på ett sätt som begränsar oro och skapar tillit. Oberoende av testmetod är en audionom med tålamod och vana att samarbeta med personer med utvecklingsstörning en viktig förutsättning för framgångsrik och säker testning.

Full text
Abstract:
Oceanic anoxic events occur in response to significant climate perturbations. This study focuses on the late Cretaceous OAE 2, which occurred across the Cenomanian-Turonian boundary (CTB), ~93.9 Ma. Multiple isotope proxies have reviewed the implications of palaeocirculation, volcanism and climate change to assess the driving mechanism(s) associated with global anoxia. Utilising geochemistry and geochronology (Os, Ca and U-Pb) this study provides a greater understanding of palaeoclimate conditions and assesses the global extent of anoxia. Hitherto, analyses have focussed on sections in and around the proto-North Atlantic. Herein, high-resolution 187Os/188Os isotope stratigraphy from 8 globally representative sections is presented; Portland #1 core, Site 1260, Wunstorf, Vocontian Basin, Furlo, Site 530, Yezo Group, and Great Valley Sequence. The Re-Os system is sensitive to regional and global variation in seawater chemistry on the order of the residence time of Os due to ocean inputs: radiogenic Os from continental weathering and unradiogenic Os from hydrothermal inputs. The initial 187Os/188Os (Osi) profiles present a globally ubiquitous trend: radiogenic Os values are attenuated by unradiogenic Os for ~200 kyr, which then gradually return to radiogenic Os. Minor discrepancies illustrate the sensitivity of local water masses as a function of basin connectivity and global sea level; i.e., Portland, Great Valley Sequence and Yezo Group (temporally restricted basins) vs. Site 1260 and Site 530 (open ocean). Furthermore, a temporal framework is developed from existing ages (from the Western Interior, USA) and new U-Pb zircon geochronology (Yezo Group, Japan) to quantify the duration of OAE 2 and volcanic activity at the Caribbean LIP. Age models are applied and support the revision of the stratigraphic position of the OAE 2 onset and the CTB in the Yezo Group. The integration of the Western Interior and Pacific geochronology quantitatively verifies that the OAE 2 was globally synchronous occurring at ~94.4 Ma ± 0.15 Ma. In addition, marine δ44Ca records from 4 global OAE 2 sections are presented. The seawater mixing models reveal that δ44Ca values show no appreciable change to riverine or hydrothermal influx. Herein, I quantitatively demonstrate that fractionation is a parameter for δ44Ca isotopic variation at Portland and Pont d’Issole, which may be attributed to diagenetic reactions in the marl-rich lithology leading to site-specific fractionation. Therefore, marine δ44Ca profiles are different in each section as a function of varying fractionation factor. Ca isotope systematics are highly complex and so further work is crucial in order to develop our understanding of other parameters and to establish which, if any, is the most influential.

Abstract:
Les changements climatiques sont plus que jamais expliqués et détaillés par les recherches scientifiques. Malgré tout, les négociations climatiques et les mesures internationales semblent avancer à une vitesse inférieure à ce que leurs rapports scientifiques recommandent. Il existe, cependant, plusieurs initiatives telles que les marchés du carbone qui, sans être mondiaux, émergent partout dans le monde. Ceux-ci ont peut-être le potentiel de produire une pression suffisante sur les émetteurs de CO[indice inférieur 2] afin de diminuer l’amplitude de la crise climatique qui guette l’humanité. Les marchés du carbone en activité sont régionaux, étatiques ou internationaux, mais il y aura très probablement, dans les prochaines années, un premier marché du carbone mondial et celui-ci sera sectoriel. En effet, le secteur de l’aviation civile internationale par le biais de l’Organisation de l’aviation civile internationale (OACI), projette de mettre en place un mécanisme de marché d’ici 2020. Dès 2005, l'encadrement des émissions de l'aviation civile internationale est étudié par la Commission européenne et l'étude aboutit à une décision officielle en 2008. Ainsi, a-t-elle décidé, dès le début de l’année 2013, de taxer, par le système communautaire d’échange de quotas d’émission européen tous les vols en provenance et au départ de destinations internationales traversant l’Union européenne. La décision de l'Union européenne a probablement précipité les négociations au sein de l’OACI, car elle a provoqué un véritable conflit diplomatique. En effet, de nombreux pays ont montré un désaccord certain avec cette mesure. Depuis, l’Union européenne a reporté l’ajout de l’aviation civile internationale dans son marché du carbone afin de diminuer les tensions en vue de la 38e Assemblée de l’OACI qui a eu lieu à la fin de 2013 et qui a abouti à la décision importante de mettre en place une mesure basée sur le marché pour 2020. Cependant, plusieurs désaccords ont émergé des négociations. Ainsi, dans ce mémoire, nous présenterons l’état de la situation et répondrons aux questions suivantes : quelles sont les dissensions au sein de l’OACI sur l’élaboration d’une mesure basée sur le marché et comment peuvent-elles être atténuées?

Full text
Abstract:
Otoacoustic Emissions (OAE) are minute acoustic responses originating from the cochlea as a result of an external acoustic stimulus and are recorded using a sensitive microphone placed in the ear canal. OAEs are acquired by synchronous stimulation with an acoustic click or tone burst and recording of the post-stimulus responses. This method of acquiring OAEs is known as transient evoked otoacoustic emissions (TEAOE) and is commonly used in clinics as a screening method for hearing and cochlear functionality in infants. Recently, a novel method of acquiring OAEs utilizing a swept-tone, or chirp, as a stimulus was developed. This method used a deconvolution process to compress the swept tone response into an impulse or click-like response. Because the human ear does not hear all frequencies (pitches) at equal loudness the swept-tone stimulus was equalized in amplitude with respect to frequency. This equalized stimulus will be perceived by the ear as equally loud in all frequencies. In this study a new hearing level equalized stimulus was designed and the OAE responses were analyzed and compared to conventional click evoked OAEs. The equalized swept-tone stimulus evoked greater magnitude OAE responses when compared to the conventional methods. It was also able to evoke responses in subjects that had little TEOAEs which might fail conventional hearing screening.

Formation exposed near the YeniceSihlar village of Mudurnu (Bolu). Field and thin-section analyses showed that the Ü

mlü
Formation is composed of cm to m scale cycles of 4th and 5th order. The 4th order cycles are equivalencies of parasequences and have 0.4 Ma average duration. 5th order cycles are interpreted as episodic. Upper Albian (OAE1c or OAE1d) and Cenomanian/Turonian (OAE2) anoxic events are observed as black shale levels in the studied section. Position of black shale levels is interpreted using cyclostratigraphy and sequence stratigraphy. Four types of cycle are determined. A and B-type cycles are placed in transgressive and Highstand System Tract. C and D-type cycles are placed in Lowstand System Tract. Two type 3 and one type 1 sequence boundaries are recorded. The boundary between the Sogukç
am Limestone and the Ü

mlü
Formation is interpreted as the first type 3 sequence boundary. The second one separates the Ü

mlü
Formation and the Yenipazar Formation and is observed at the top of the section. Type 1 boundary is represented by a conglomeratic level in the middle of the succession. Provenance analysis of sandstones indicates that during the Cenomanian the source area changed from magmatic arc setting to continental setting.

Abstract:
La proliferazione della civiltà egizia è stata possibile solo grazie alla presenza del Nilo. Da qui lo spunto per indire un concorso sulla progettazione di un polo museale che racconti i motivi dello sviluppo della popolazione egiziana. Il concorso è stato preso come riferimento per questa tesi in quanto nata dall’esigenza di un confronto personale con un’architettura diversa da quelle affrontate in precedenza durante il percorso accademico. Ciò che oggi si conosce dell’architettura egizia è basato principalmente sui monumenti religiosi, da quelli di culto a quelli funerari, che sono stati oggetti di studio per comprenderne e rivisitarne gli stilemi, associandoli ad una tipologia di architettura differente, quella museale. La progettazione di un museo è accompagnata da notevoli difficoltà, quali la corretta distribuzione e la piena fruizione degli spazi espositivi, di intrattenimento e privati, una giusta illuminazione interna e un adeguato inserimento dell’opera nel contesto ambientale. Si è voluto infatti, in primo luogo, creare una relazione sia con il fiume che con il deserto presente a Nord dell’area indicata: il museo è stato disposto col suo sviluppo longitudinale in direzione dei due temi ambientali, in modo da creare un cannocchiale visivo attraverso la duna che li separa. Per realizzarlo, si è concepita l’opera come una frattura del terreno stesso, la cui morfologia ha reso necessario uno studio attento delle quote altimetriche, ottenendo così una corte centrale protetta su tre lati e scoperta verso il Nilo. La frattura è stata rappresentata attraverso una pelle geometrica che viene fuori dalla duna e che nella corte si solleva per unificare gli spazi esterni con quelli interni, per i quali è stato svolto uno studio approfondito. A differenza dell’aspetto impiantistico che, a causa della scelta di una scala elevata, non è stato analizzato dettagliatamente, l’elemento cardine di questo progetto di tesi è stato il rapporto con l’ambiente circostante.

The construction sector presents a historic of problems related to the quality of its products, services and processes. Many researches and initiatives against such problems have been conducted by researchers, professionals and organizations from the wide field covered by this sector.Making use technological innovations, methods and tools adapted from other industrial sectors and experiences gathered from development of the design and execution processes, the construction sector in Brazil has shown progress on the performance improvements, due to efforts undertaken in the last decades, mainly on the building construction segment.Part of the solutions to these problems points to the need of improvement in the management mechanisms of the design process and the integration between the design and execution activities. This research takes this field for granted, leading the focus to the special art constructions, expression used to kinds of constructions such as bridges and viaducts. The methodology of the case study was used to attend of a large sized viaduct project development in which some basics of the Concurrent Engineering are evaluated in order to improve the quality of the product and also of other processes involved in construction sector. This approach is based on the methods and tools studied on the literature revision; in the specific features of the sector, completed by a research done with the professionals of the bridges and viaducts designs; and also by the analysis of the case study emphasizing the aspects of the design-production integration in the design process, besides a discussion about the way of contracting engineering services. The case study shows that a bigger integration between design and production using the Concurrent Engineering concepts, has allowed the constructive rationalization and the decrease of the costs in the construction.

Abstract:
Les Evénements Océaniques Anoxiques (OAE) sont des événements extrêmes qui se sont pro- duits majoritairement durant le Crétacé et qui sont caractérisés par un enfouissement massif et brutal de carbone organique. Ces événements ont été très étudiés durant ces 40 dernières années mais aucun consensus n’a été atteint quand aux processus à l’origine de leur déclenchement. Pour tenter de répondre aux questions encore en suspens, nous avons réalisé une étude géochimique approfondie (éléments majeurs et traces, compositions isotopiques en Nd et Hf) des différentes fractions (détritiques et authigènes) de sédiments marins déposés lors de l’événement océanique anoxique associé à la limite Cénomanien-Turonien (OAE2, 93.5Ma). Les deux sections étudiées représentent différents environnements de dépôt : un environnement peu profond et proche des sources continentales (Taghazoute, Maroc) et un environnement marin profond, loin des côtes (DSDP Site 367, Cap-Vert).A l’approche de l’OAE2, les compositions isotopiques du Nd et de l’Hf ne présentent que peu de variations. Ces observations reflètent une absence de changement dans le régime d’érosion continentale en amont des deux sections étudiées. Notre étude diverge du scenario proposant qu’un fort apport de nutriments résultant d’une altération continentale accrue soit à l’origine des OAEs. En revanche, les variations isotopiques (Nd) mesurées dans les fractions authigènes du Site 367, interprétées comme reflétant la composition océanique passée, supportent l’idée d’une contribution magmatique dans l’Océan Atlantique durant l’OAE2. Ces nouveaux résultats sont cohérents avec de précédentes études et confortent le rôle des grandes provinces magmatiques (plateau des Caraïbes) dans l’eutrophisation des océans qui précède les événements anoxiques.En outre, l’étude combinée des terres rares (REE) et des compositions isotopiques (Nd) de fractions authigènes obtenues par extraction chimique (leaching) démontre l’incorporation de matériel détritique dans ces fractions en milieu peu profond. Ces nouvelles observations questionnent l’idée que toute fraction authigène enregistre une composition chimique océanique pure. Enfin, l’étude complète des concentrations en éléments traces de ces mêmes fractions souligne le rôle important de la lithologie des sédiments sur la composition des leachates. Cette étude questionne également l’utilisation de certaines méthodes de leaching qui semblent favoriser l’extraction de phases détritiques externes lorsque les sédiments sont soumis à des étapes de leaching répétées
Oceanic Anoxic Events (OAE) are brief and extreme events that mostly occurred during the Cretaceous and are defined by the burial of massive amounts of organic carbon. These events have been intensely investigated in the last 40 years but the mechanism that triggered OAEs remains problematic. In order to better constrain what causes these events, we realised a complete geochemical study (major and trace elements, isotopic compositions of Nf and Hf) of various sedimentary fractions (detrital and authigenic) for marine sediments associated with the Cenomanian-Turonian boundary event or OAE2 (93.5 Ma). We focused our study on two marine sections that represent different depositional settings : a shallow marine setting, close to the continental shelf (Taghazoute, Morocco) and a abyssal marine section (DSDP Site 367, Cape-Verde), far from the African shelf.The remarkable stability of the Nd-Hf decoupling in both sections indicates no obvious change of continental weathering approaching OAE2. Our conclusions diverge from the hypothesis that proposes an higher nutrient input through an enhanced continental weathering as a triggering mechanism of OAEs. However, Nd isotopic compositions of authigenic fractions measured at Site 367, interpreted as past oceanic composition, exhibit a positive isotopic excursion and indicate a magmatic contribution in the deep Atlantic Ocean during OAE2. These new data are consistent with previous isotopic studies and support the role of Large Igneous Province (in our case, the Caribbean Plateau) as nutrient provider and triggering mechanism of anoxic events.The combined study of rare earth elements (REE) and Nd isotopic compositions of authigenic fractions recovered by leaching demonstrates the incorporation of detrital material in authigenic fractions in shallow marine settings. These new results challenge the traditional belief that authigenic material always records an untouched seawater composition. Finally, the extensive study of trace element concentrations of these same fractions demonstrated the strong impact of sample lithology on their trace element content. Our study also questions the relevance of sequential leaching methods that facilitate external contamination when sediments are submitted to repeated leaching steps

Le débat sur l’importance et le rôle de la propriété intellectuelle dans le développement en Afrique s’est jusqu’ici focalisé sur les brevets d’invention au détriment d’autres formes d’appropriation de droits intellectuels telles que le droit des dessins et modèles industriels. Pourtant l’exploitation des droits sur les créations ornementales est susceptible de générer des valeurs économiques pouvant contribuer à la réalisation des objectifs de développement des pays africains. L’efficacité d’une telle valorisation est entre autres tributaire de l’existence d’un système de protection servant de tels objectifs, ainsi que d’une réglementation internationale favorisant l’exploitation transnationale des dessins et modèles industriels et tenant compte du niveau et des besoins de développement des pays africains.

The debate on the importance and the role of intellectual property in the development in Africa was focused up to now on patents at the expense of other forms of appropriation of intellectual rights such as industrial designs’ right. However, the commercialization of the rights on ornamental creations is likely to generate economic values that could contribute to the realization of development objectives of African countries. The effectiveness of such a valorisation among other things is dependent on the existence of a protection system created to meet such objectives, as well as an international rules supporting the transnational commercialization of industrial designs and taking into account the level and the needs for development of African countries.

The present work of two Lower Aptian deposits, Madotz (N Spain) and Curití Quarry (Colombia), is a multiproxy study that includes fossil assemblages, microfacies, X-ray diffraction bulk and clay mineralogy, elemental analyses (major, minor, trace elements), Rock-Eval pyrolysis, biomarkers, inorganic and organic carbon content, and stable carbon isotopes. The results provide baseline evidence of the local and global controlling environmental factors influencing OAE-1a in shallow-water settings. The data also improve our general understanding of the conditions under which organic-carbon-rich deposits accumulate. The sequence at Madotz includes four intervals (Unit 1; Subunits 2a, 2b and 2c) that overlap the times prior to, during and after the occurrence of OAE-1a. The Lower Unit 1(3m thick) is essentially siliciclastic, and Subunit 2a (20m) contains Urgonian carbonate facies that document abruptly changing platform conditions prior to OAE-1a. Subunit 2b (24.4 m) is a mixed carbonate-siliciclastic facies with orbitolinid-rich levels that coincides with OAE-1a δ13C stages C4-C6, and is coeval with the upper part of the Deshayesites forbesi ammonite zone. Levels with pyrite and the highest TOC values (0.4-0.97%), interpreted as accumulating under suboxic conditions, and are restricted to δ13C stages C4 and C5. The best development of the suboxic facies is at the level representing the peak of the transgression. Subunit 2c, within δ13C stage C7, shows a return of the Urgonian facies. The 23.35-m section at Curití includes a 6.3-m interval at the base of the Paja Formation dominated by organic-rich marlstones and shales lacking benthic fossils and bioturbation, with TOC values as high as 8.84%. The interval overlies a level containing reworked and phosphatized assemblages of middle Barremian to lowest Aptian ammonites. The range of values and the overall pattern of the δ13Corg (-22.05‰ to -20.47‰) in the 6.3m-interval is comparable with Lower Aptian δ13C stage C7. Thus, conditions of oxygen depletion at this site also occurred after Oceanic Anoxic Event-1a, which developed between carbon isotope stages C3 and C6. Both sites, Madotz and Curití, attest to the importance of terrigenous and nutrient fluxes in increasing OM productivity that led to episodic oxygen deficiency.

Abstract:
This study assessed the role of otoacoustic emission screening for the early identification of noise-induced hearing loss in South African mineworkers. Transient otoacoustic emissions and distortion product otoacoustic emissions were recorded in 106 noise exposed mineworkers (212 ears) aged between 20 and 55 years, and in 17 non-exposed novice workers (34 ears) aged between 18 and 29 years. All subjects had normal hearing acuity, otoscopic examinations and immittance measurements. Four otoacoustic emission (OAE) measurements were taken per ear and repeated by a second audiologist for the evaluation of inter-test reliability. Age and number of years of noise exposure was additionally evaluated as well as the specificity and sensitivity of the tests for this population group. In general the OAEs were diminished at four KHz for both the exposed and non-exposed groups. Age was found to be the primary predictor of diminished OAE tracings. Poor inter-test reliability was obtained. These results indicate that further research is required within this population group before OAE testing can be implemented for screening for noise-induced hearing loss.

Abstract:
Storage, preservation and access of Master's and PhD theses as well as their abstracts in an electronic form provide unique opportunities to the academic community in Lithuania as well as worldwide. The main aims of this project were to establish an archive (Lithuanian ETD IS) of Lithuanian student final year projects, PhD theses and their abstracts in an electronic form (ETD). This archive should become a part of the Lithuanian academic library network (LABT), ensuring registration and storage of ETD documents, and should be accessible by the academic community in Lithuania and the rest of the world. In order to develop the Lithuanian ETD IS, the most widely used formats and methods for access, retrieval and exchange with NDLTD and other national ETD projects were employed. A solution, ensuring efficient ETD registration, preservation, retrieval and access by users, is presented and discussed. Application of the ExLibris programming products (ALEPH500™, MetaLib™, SFX™), developed during the LABT project, was used.
