Le présent mémoire a pour ambition d'analyser la nature juridique et les particularismes du contrat de progiciel. Dans une première partie, nous examinerons les obligations mises à la charge des parties puis nous tenterons de qualifier le contrat de progiciel au regard du droit civil. Dans une seconde partie, nous examinerons la formation du contrat de progiciel dans un environnement traditionnel puis dans les environnements électroniques. Nous aborderons plus particulièrement deux nouveaux modes de formation des contrats, que sont les mécanismes du «shrink-wrap» et du «click-wrap». Nous analyserons ensuite les clauses limitatives ou exonératoire de garantie et de responsabilité, la clause d'élection de for et les clauses relatives à la propriété intellectuelle. / This thesis is intended to analyse the nature and the particularities of software license package contracts. Firstly, the obligations of each party will be studied, after which it shall be endeavoured to qualify the software license package contract with regard to civil law. Secondly, the creation of the software license package contract in a generalised situation as well as in an electronic environment will be examined. Furthermore, two new methods of contract creation will be contemplated, namely the "shrink-wrap" and the "click-wrap" methods. Finally, clauses limiting or exonerating responsibilities and guaranties, the de for election clause and clauses in relation to intellectual property will be analysed.

This thesis examines the microeconomic consequences of the arrival of open source in the software market. Specifically, it analyzes three features of open source software by using specific models of industrial organization. Open source software is free, and may be modified or duplicated by anyone. The first paper studies the entry of an open source software in a closed source software market. Using a model of horizontal differentiation, the analysis considers a closed source firm's investment in the quality of its software. The introduction of open source on the market reduces the firm's investment in quality and increases the price of its software. Moreover, the entry of open source software may reduce consumer welfare. Post-entry by an open source software, the reduction in market share lowers the firm's incentive to invest in quality. The second paper features vertical differentiation to study a monopolist selling supporting product to its software. The study begins by contrasting the supply of support by an open source provider and a closed source vendor. The model shows that in both cases the levels of support offered are the same. In addition, consumer welfare is higher and profit lower under an open source software. Then, the paper considers the competition in the provision of support. Here, the supply of high level support is greater than under a monopolist. Finally, the monopolist adopts a dual licensing strategy to extract more surplus from developers interested in modifying open source software and redistributing the resulting product. This technique, when the developers place high value on the source code, generates more profit if the monopolist chooses to publish as open source rather than closed source. The last paper studies how a closed source firm is affected by the introduction of an open source benefiting from contributions by users. A vertical differentiation model is used, and reveals that, when contribution of users is present, the closed source vendor may lower its price to a level where it forces the open source out of the market. The firm's lower price not only increases demand for its software, but also induces consumers into switching from open to closed source software therefore reducing the contribution of users. / Les logiciels libres sont uniques en leur genre\ : non seulement sont-ils distribués gra-tuitement, mais on peut aussi les modifier et les copier. Cette thèse étudie l'impact de ces propriétés du logiciel libre sur la compétition et sur les entreprises de logiciel propriétaire. Des modèles propres à l'organisation industrielle sont utilisés. Le première étude examine l'arrivée d'un logiciel libre sur un marché occupé par un logiciel propriétaire. En utilisant un modèle de différenciation horizontale, le papier consi-dère une firme propriétaire qui investit dans la qualité de son logiciel. L'arrivée d'un logiciel libre cause l'entreprise du logiciel propriétaire à réduire le niveau de son investissement et à augmenter le prix de son produit. Il s'avère alors que l'introduction du logiciel libre sur le marché réduit l'investissement de l'entreprise et engendre même l'augmentation du prix du produit. De plus, l'arrivée du logiciel libre peut réduire le niveau de bien-être des consommateurs. Comme le logiciel libre ne réagit pas aux décisions stratégique de l'entreprise, cette dernière voit son marché réduit peu importe sa stratégie. La firme décide conséquemment de vendre un produit de moindre qualité à un prix plus élevé à une clientèle réduite. Le deuxième papier propose un modèle qui utilise la différenciation verticale afin d'exa-miner un monopoleur offrant un produit complémentaire à son logiciel. L'étude compare d'abord les cas d'un logiciel libre et d'un logiciel propriétaire, toujours dans le contexte d'un monopoleur offrant du support professionnel pour son logiciel. Il est établi que le bien-être des consommateurs est plus élevé, et le profit inférieur dans le cas d'un distributeur de logiciel libre. Ensuite, le modèle initial est modifié avec l'ajout d'une seconde entreprise offrant du support professionnel. Dans ce cas, l'offre de support de haut niveau est plus élevée. Finalement, le monopoleur adopte une stratégie de licences doubles. Ce concept permet au monopoleur de proposer la vente d'une licence même si son logiciel est libre. Cette technique génère plus de profits, certaines conditions étant présentes, que si l'entreprise optait pour un logiciel propriétaire. Un logiciel libre profite des contributions de ses usagers pour améliorer son produit. Le troisième papier examine l'arrivée d'un tel produit sur un marché dominé par un logiciel propriétaire. Le modèle de différenciation verticale utilisé contraste les deux logiciels dans un marché donné et révèle que la contribution des utilisateurs peut diminuer la part de marché du logiciel libre au profit de son conccurrent. De fait, en diminuant ses prix le licenceur du logiciel propriétaire incite le consommateur à délaisser le logiciel libre pour le produit de son concurrent.

Embora recente em termos históricos, a preocupação de indivíduos e governos quanto à capacidade de suporte do meio, face aos efeitos das intervenções antrópicas e da enorme probabilidade de danos irreparáveis para as condições de todas as formas de vida, implicou na necessidade da gestão dos recursos ambientais e do disciplinamento dessas intervenções, buscando-se instrumentos técnicos e jurídicos adequados. A avaliação de impacto ambiental (AIA) e o licenciamento ambiental com eficaz participação da sociedade, são cruciais para abalizar decisões e garantir um mínimo de sustentabilidade ambiental. A inserção do Brasil nesse contexto se dá com a lei nº 6938/81, que estabelece a Política Nacional do Meio Ambiente (PNMA), porém, ganha corpo na Constituição Federal de 1988, com a exigência sine quan non de prévia elaboração e publicidade do Estudo de Impacto Ambiental (EIA) para as hipóteses de degradação ambiental significativa. Nada obstante, a Secretaria do Meio Ambiente do Estado de São Paulo edita a Resolução SMA nº 42/94, permitindo o licenciamento subsidiado apenas em um incógnito Relatório Ambiental Preliminar (RAP), instrumento técnico de elaboração prévia obrigatória, quebrando a aparente harmonia normativa até então vigente. Restou evidenciado neste trabalho que a própria Resolução SMA nº 42/94, assim como o RAP, que não tem seu conteúdo mínimo fixado na regra jurídica que o criou, são objetos de dissensões técnicas e jurídicas que possibilitam o questionamento do procedimento de licenciamento ambiental quanto à sua legitimidade, o que pode levar à anulação da licença ambiental expedida por vício de origem. / Although historically recent, the individual and governmental preoccupation towards the capacity of nature to provide for the human beings, due to their interventions and the enormous probability of irrecoverable damage to the conditions of life for all forms of lives, has engendered the necessity for the orderly management of the natural resources, seeking technical and legalized instruments for the task. The Environmental Impact Statement (EIS), and the environmental licensing, plus the efficient society participation, are crucial to backup decisions and assure a minimum of environmental sustainability. Brazil\'s insertion in this context begins with the Law nº6938/81, which establishes the National Environment Policy (PNMA, in Portuguese), and is enhanced in the Federal Constitution of 1988 by the sine qua non requirement of previous elaboration and publicity of the EIS. Notwithstanding, the rules imposed by the Environmental Office of the Government of São Paulo State (SMA, in Portuguese) Resolution nº 42/94 endorsing the licensing subsidized solely by an incognito Preliminary Environmental Report (RAP, in Portuguese), shattered the seemingly normative harmony existent and became a source for dissensions that make it possible to question the legitimacy of the license issued. It is evinced in this work that the very Resolution SMA nº 42/94, along with the RAP - which has not its minimum contents described by the rule that created it - are subject to technical and juridical dissensions that might give room to the questioning of the environmental licensing as to its legitimacy by a flaw, that might lead to the annulment of the issued license.

The Supremo Tribunal Federal rules that the rights on the urban law happens with the start of the works, dully licensed by the local public office. On the other hand, most cities in Brazil defines that this moment really happens when the owner submitt the License Permit to the City Offices. Based on the Constitutional Principles of Urban Planning, the intent of this paper is to demonstrate that the the proper moment for the acquisition of the rights is exactily when the license is granted by the local autorirty. Is is also sugested that all the process of annalises of construction permits should be suspended during the phases of alteration or revision of City Regulation Plans / A ideia central deste trabalho é discutir a questão do direito adquirido no âmbito do direito urbanístico. O Supremo Tribunal Federal (STF) entende que o direito adquirido no âmbito do direito urbanístico se dá com o início da obra regularmente licenciada pelo poder público local. No entanto, o ordenamento jurídico dos municípios brasileiros estabelece que esse momento se consolida quando o proprietário protocola seu pedido de licença perante a Administração Pública Municipal. A partir da interpretação do princípio constitucional do planejamento urbano pretendese demonstrar que o momento da constituição do direito adquirido se dá quando da concessão da licença urbanística. Defende-se, também, a necessidade de suspensão dos processos administrativos tendentes à concessão de licenças urbanísticas no curso do processo de alteração ou revisão de planos diretores

Em termos metodológicos, a pesquisa se apoiou na revisão sistemática da literatura adotada tanto para oferecer o devido embasamento teórico sobre licença social para operar e justiça ambiental, quanto para apoiar a construção de instrumentos de coleta de dados aplicados junto a distintos stakeholders. Dentre os resultados destacaram-se: a necessidade de um maior esforço por um diálogo para além dos requisitos legais para licenciamento dos empreendimentos, assim como a busca por uma maior contribuição da academia e poder público na comunicação e esclarecimentos sobre os riscos e impactos locais do empreendimento, e suas respectivas oportunidades, quando existem. / This study aims to analyze the impacts of the implementation from LNG projects (liquefied natural gas) and LPG (liquefied petroleum gas) by an oil company and natural gas to the fisherfolk of Magé, State of Rio de Janeiro in the period 2007-2016. In terms of methodology, the research relied on the systematic review of the literature to both provide theoretical basis of social license to operate and environmental justice, and to support the construction of data collection instruments applied along the different stakeholders. The results highlighted the need for a greater effort for dialog beyond the legal requirements for the licensing of enterprises, as well as the search for a greater contribution of academia and public power in communication on the local risks and impacts, as their opportunities, when it exists.

In order to accomplish that, we have analyzed the historical origins, the theoretical influences mainly the reflective practice, according to Donald Schön, and the competences, according to Philippe Perrenoud the relations between theory and practice and the interferences of international fomentation agencies, such as World Bank, in the elaboration of official directives. Soon afterwards, we have done four interviews where coordinators of higher education institutions were invited to expose their ideas, doubts and suggestions concerning the reformulation of licensing courses in Mathematics due to the new demands imposed by the Resolutions 01 and 02 of CP/CNE in 2002. We have checked, according to the coordinators of licensing courses of Mathematics, that the fundamental concepts transmitted by the present legislation and the discussions are innocuous if compared to the serious problems the licensing courses in Mathematics are facing nowadays. By the way, this seems to be one of the great implications of the governmental proposes: being far from the reality of the courses. We have also checked that the governmental proposes were not totally put into practice in the courses, what should have happened in February 2004. On the other hand, the coordinators have proposed alternatives to overcome the existing contradictions in the elaboration of the official directives, what make us think that, with a little bit of information and the spread of the existing researches, other institutions of higher education will have remarkable results in the reformulation of their courses / O presente trabalho tem como objetivo pesquisar a formação de professores de Matemática no Brasil, analisando as propostas apresentadas e interpretações que estão sendo feitas pelos coordenadores de cursos de Licenciatura em Matemática a respeito da atual legislação oficial para formação de professores, no momento atual. Para tanto, analisamos a origem histórica, as influências teóricas principalmente a prática reflexiva, segundo Donald Schön, e as competências, segundo Philippe Perrenoud as relações entre teoria e prática e as interferências de agências de fomento internacional, como o Banco Mundial, na elaboração das diretrizes oficiais. Em seguida, realizamos quatro entrevistas, em que os coordenadores de instituições de ensino superior foram convidados a expor suas idéias, dúvidas e sugestões a respeito da reformulação dos cursos de Licenciatura em Matemática face à nova demanda imposta pelas Resoluções 01 e 02 do CP/CNE de 2002. Constatamos, por parte dos coordenadores de cursos de Licenciatura em Matemática, que os conceitos fundamentais veiculados pela atual legislação e as discussões tornam-se inócuas, frente aos graves problemas que os cursos de Licenciatura em Matemática enfrentam atualmente. Aliás esta parece ser uma grande implicação das propostas governamentais: estar longe da realidade dos cursos. Notamos, também, que as propostas governamentais não foram totalmente colocadas em prática nos cursos, o que deveria ter ocorrido em fevereiro de 2004. Por outro lado, os coordenadores propuseram alternativas para superarem as contradições existentes na elaboração das diretrizes oficiais, o que nos leva a crer que, com um pouco de informação e a disseminação das pesquisas existentes, as instituições de ensino superior poderão obter resultados expressivos na reformulação de seus cursos

人類經濟活動重心之變革推動著產業競爭的樣貌，於二十一世紀的今日，知識已成為經濟活動中最主要之價值驅力，與之相應的，產業中智慧財產層面的競爭也逐漸受到重視，發展至今，智慧財產已深入產業鏈且細化為各種以智慧財產運用為中心以創造獲利之企業。 半導體產業於台灣經濟發展之推進中佔有關鍵性之地位，隨著台灣廠商在全球產業鏈中扮演的角色重要性與日俱增，難以避免必須因應半導體產業中由智慧財產所造就的新興商業模式，其中，智慧財產研發公司拋棄舊有以生產製造為主之商業模式，開創以知識為本的競爭場域，並挾其智慧財產進行全球化的授權以及訴訟，扮演著遊戲規則的創造者，尤其記憶體產業之兩大智慧財產研發公司Rambus Inc.以及Tessera Technology Inc.，自2000年起不斷於全球提起專利訴訟，對整體產業乃至於台灣廠商帶來無法忽視之影響。 本研究試圖建立分析智慧財產研發公司之架構，亦即由該等公司之策略演進出發，宏觀的了解其於變動的競爭環境中如何發揮企業優勢；其次，以公司策略定位為基礎，進一步推動資源投入之分配，並形塑商業模式的產生；最後，本研究萃取智慧財產研發公司商業模式中較具特色且影響廣泛之訴訟階段，藉由記憶體產業中之個案分析比較之方式進行深入之實證研究，以管窺該等公司之專利運用模式，期能透過提升對於智慧財產研發公司策略定位、商業模式以及訴訟模式之了解，活化企業智慧財產之管理，並提供台灣廠商面對專利授權與訴訟時因應之基礎。 / The revolution of economic activities of human beings has been the force behind the changing format of competition among industries. In the contemporary 21st century, knowledge has become one of the most valuable forces in economic activities; correspondently, the competition strategy of intellectual property also seized much attention. As of today, intellectual property has already been integrated in each and every industry chains and developed into various enterprises which earn profits by operating it. Semi-conductor industry played an important role in the process of Taiwan’s economic development. As Taiwanese companies claim more crucial roles in the global industry chain, they are inevitably forced to deal with the new business model established by the creation of intellectual properties. Among them, intellectual property development companies have withdrawn from old business model of production and manufacturing and create a new competition field on the basis of intellectually properties. Intellectual property development companies engage in global wide license and litigation, acting as the rule-maker within the new frame of competition. Rambus Inc. and Tessera Technology Inc. are the two leading intellectual property development companies which brought lawsuits internationally since 2000, creating serious impacts on both the entire industry and Taiwanese companies. This research aims to establish an analytical framework to observe intellectually property development companies, starting from the progress of strategy, try to understand how to exercise their advantages in the ever-changing competitive business world; furthermore, based on business strategies, this research look further into the distribution of resources and the creation of business models; lastly, this research closely examines the litigation phase of the business model of intellectual property development companies by comparative case studies, in order to conclude the operation pattern of patents of such companies. With further exploration on the strategic positioning, business model and litigation pattern of intellectual property development companies, this research provides not only a deeper understanding on the management of IPRs but also a framework for Taiwanese companies to cope with patent licenses and litigations.

A 15.5-mile portion of the I-85 high-occupancy vehicle (HOV) lane in the metropolitan area of Atlanta, GA was converted to a high-occupancy toll (HOT) lane as part of a federal demonstration project designed to provide a reliable travel option through this congested corridor. Results from the I-85 demonstration project provided insight into the results that may follow the Georgia Department of Transportation's planned implementation of a $16 billion HOT lane network along metropolitan Atlanta's other major roadways [2]. To evaluate the impacts of the conversion, it was necessary to measure changes in corridor travel speed, reliability, vehicle throughput, passenger throughput, lane weaving, and user demographics. To measure such performance, a monitoring project, led by the Georgia Institute of Technology collected various forms of data through on-site field deployments, GDOT video, and cooperation from the State Road and Toll Authority (SRTA). Changes in the HOT lane's speed, reliability or other performance measure can affect the demographic and vehicle characteristics of those who utilize the corridor. The purpose of this particular study was to analyze the changes to the vehicle characteristics by comparing vehicle occupancy, vehicle classifications, and vehicle registration data to their counterparts from before the HOV-to-HOT conversion. As part of the monitoring project, the Georgia Tech research team organized a two-year deployment effort to collect data along the corridor during morning and afternoon peak hours. One year of data collection occurred before the conversion date to establish a control and a basis from which to compare any changes. The second year of data collection occurred after the conversion to track those changes and observe the progress of the lane's performance. While on-site, researchers collected data elements including visually-observed vehicle occupancy, license plate numbers, and vehicle classification [25]. The research team obtained vehicle records by submitting the license plate tag entries to a registration database [26]. In previous work, vehicle occupancy data were collected independently of license plate records used to establish the commuter shed. For the analyses reported in this thesis, license plate data and occupancy data were collected concurrently, providing a link between occupancy records of specific vehicles and relevant demographic characteristics based upon census data. The vehicle records also provided characteristics of the users' vehicles (light-duty vehicle vs. sport utility vehicle, model year, etc.) that the researchers aggregated to identify general trends in fleet characteristics. The analysis reported in this thesis focuses on identifying changes in vehicle characteristics that resulted from the HOV-to-HOT conversion. The data collected from post-conversion are compared to pre-conversion data, revealing changes in vehicle characteristics and occupancy distributions that most likely resulted from the implementation of the HOT lane. Plausible reasons affecting the vehicle characteristics alterations will be identified and further demographic research will enhance the data currently available to better pinpoint the cause and effect relationship between implementation and the current status of the I-85 corridor. Preliminary data collection outliers were identified by using vehicle occupancy data. However, future analysis will reveal the degree of their impact on the project as a whole. Matched occupancy and license plate data revealed vehicle characteristics for HOT lane users as well as indications that the tested data collectors are predominantly synchronized when concurrently collecting data, resulting in an argument to uphold the validity of the data collection methods. Chapter two provides reasons for why HOT lanes were sought out to replace I-85's HOV lanes. Chapter two will also provide many details regarding how the HOT lanes function and it will describe the role the Georgia Institute of Technology played in the assessment the HOV-to-HOT conversion. Chapter three includes the methodologies used to complete this document while chapter four provides results and analysis for the one year period before the conversion and the one year period after the conversion.

Καθώς η Κοινωνία της Πληροφορίας αναπτύσσεται με ταχύτατους ρυθμούς, οι τεχνολογικές κατακτήσεις από το χώρο της επιστήμης των υπολογιστών και τηλεπικοινωνιών, αποτελούν σημαντικό κεφάλαιο σε αρκετούς επιμέρους τομείς του κοινωνικού βίου, ανάμεσα στους οποίους είναι και ο Πολιτισμός. Η πολιτισμική ποικιλομορφία του υπάρχοντος υλικού και η διάθεση για αξιοποίηση της επιπρόσθετης εκπαιδευτικής του αξίας, σε συνδυασμό με την απαίτηση για διάσωση των πρωτότυπων έργων, συνθέτει ένα πολύπλοκο τεχνολογικό πρόβλημα με νομικές και κοινωνικές προεκτάσεις. Η διαδικασία της ψηφιοποίησης και η δημιουργία μιας νέας άυλης ηλεκτρονικής υπόστασης για τα έργα πολιτισμού, γεννά νέες δυνατότητες αλλά παράλληλα θέτει νέους περιορισμούς. Η έμπνευση και η δημιουργικότητα των καλλιτεχνών εκφράζεται με τα πνευματικά δικαιώματα, η προστασία και η διαχείριση των οποίων αποτελεί το αντικείμενο της διπλωματικής εργασίας. Το σύνολο των πνευματικών δικαιωμάτων και ο τρόπος που αυτά ορίζονται, δεσμεύονται, εγείρονται και μεταβιβάζονται, μεταβάλλεται ριζικά καθώς περνάμε από την πραγματική αναλογική μορφή στην άυλη ψηφιακή απεικόνιση. Στην παρούσα διπλωματική εργασία, ορίζονται οι διάφοροι τύποι δικαιωμάτων πνευματικής ιδιοκτησίας και αποσαφηνίζονται οι δεσμεύσεις και οι περιορισμοί που προκύπτουν από αυτά συναρτήσει της Διεθνούς,της Ευρωπαϊκής και της Ελληνικής Νομοθεσίας. Επίσης, καθορίζεται η ενδεικτική διαδικασία που πρέπει να ακολουθηθεί από μια οντότητα (πολύ συχνά από έναν πολιτιστικό οργανισμό) για την εκκαθάριση των δικαιωμάτων των έργων που κατέχει, κατά τη διαδικασία της Ψηφιοποίησης με σκοπό την προβολή τους στο Διαδίκτυο. Σε δεύτερη φάση, μελετάται το ευρύ φάσμα των τεχνολογικών μέσων, τα οποία μπορούν να χρησιμοποιηθούν για την προστασία των πνευματικών δικαιωμάτων που δεσμεύουν τους ψηφιακούς πόρους, παράλληλα με κάποιο κατάλληλα επιλεγμένο σύνολο μεταδεδομένων. Ιδιαίτερο τμήμα της εργασίας, αποτελούν τα συστήματα ψηφιακής διαχείρισης των πνευματικών δικαιωμάτων (DRMs). Πραγματοποιείται αναλυτική παρουσίαση των προτεινόμενων προτύπων που πρέπει να ακολουθούν τα συστήματα αυτά, όσον αφορά την αναπαράσταση και μοναδική αναγνώριση των δεδομένων, αλλά και την αναπαράσταση των δικαιωμάτων μέσων των γλωσσών περιγραφής πνευματικών δικαιωμάτων. Τέλος, παρουσιάζονται, η αρχιτεκτονική, οι βασικές λειτουργίες και η υλοποίηση ενός πρότυπου συστήματος διαχείρισης πνευματικών δικαιωμάτων για ψηφιακές εικόνες. / As Information Society is rapidly developing, technological conquests in computer science and telecommunications are becoming a very important part in many areas of social life, including Culture. The diversity of the cultural material and the intention of utilizing the added educational value, combined with the demand for preservation of the original works, compose a complex technological problem with legal and social extensions. The inspiration and creativity of the artists are expressed by Intellectual Property Rights – IPR, the protection and management of which is the subject of this thesis. The set of rights as well as the way they are specified, rised, binded and assigned changes while we pass from the analog to the materialess digital display. In this thesis we define the several types of Intellectual Property Rights and clarify the engagements and restrictions that result from them in connection with the International, European and National legislation. We also define the process that an entity (usually a cultural organization) must follow in order to clear the rights of the works it owns, during a digitization process which will lead to publication on the Internet. In the second part we study the technological solutions that can be used for the protection of IPR in parallel with a suitable metadata set. A special part of the thesis is the study of Digital Rights Management Systems – DRMs. We analytically present the standards on which modern DRMs must be based on in terms of identification and declaration of digital resources, as well as the representation of rights through rights expression languages. Finally we present the architecture, basic functionality and realization of a new Digital Rights Management System for digital images.
