La participation des pêcheurs artisanaux a longtemps été écartée de la gestion institutionnelle des activités halieutiques marines côtières dans la zone intertropicale, notamment au sein des États centralisés d’Amérique Centrale. L’objectif majeur de cette thèse était de déterminer le potentiel de cogestion des activités halieutiques artisanales au sein du Golfo Dulce (Pacifique Sud du Costa Rica). La réflexion s’organise en deux parties. La première est consacrée à l’étude de la gestion des activités halieutiques artisanales exploitant les ressources marines côtières, ressources communes, dans les pays en développement tropicaux, et la seconde, à une étude de cas du Golfo Dulce. Dans un premier temps, le secteur halieutique artisanal costaricain a été caractérisé, notamment au travers de son évolution historique et de sa gestion déconcentrée et pluri-institutionnelle. Les différentes modalités de participation des pêcheurs artisanaux à la gestion de leurs activités halieutiques sont illustrées par plusieurs études de cas (Cahuita, Marino-Ballena, Palito, Tárcoles, Golfo Dulce). Dans un second temps, les pratiques de pêche et le profil socio-économique des pêcheurs artisanaux des trois communautés de Bahía Pavones (sud-est du Golfo Dulce) ont été caractérisés. L’activité de pêche artisanale y repose sur huit espèces, dont les deux principales, Lutjanus gutattus (vivaneau rose) et L. peru (vivaneau garance) seraient surexploitées. La participation des pêcheurs artisanaux aux organisations locales est importante malgré un déficit de confiance envers ces dernières. Enfin, la comparaison des différentes études de cas a mis en évidence l’existence de huit conditions nécessaires au développement d’un processus de cogestion d’activités halieutiques artisanales au Costa Rica. Au sein de l’Aire Marine de Pêche Responsable du Golfo Dulce, malgré la volonté des pêcheurs artisanaux de participer à une pêche durable, c’est la manipulation de ces derniers par divers acteurs qui entrave le processus de cogestion. / The participation of small scale fishers in institutional management of tropical coastal marine fisheries activities has long been excluded, notably in the centralized states of Central America. The major objective of this study was to determine the potential of co-management of coastal marine small scale fisheries activities in Golfo Dulce (South Pacific of Costa Rica). The study consists of two main parts. The first analyses the management of small scale fishing activities exploiting coastal marine resources in tropical developing countries, and the second is devoted to the case study of Golfo Dulce. In a first step, the Costa Rican small scale fishery sector was characterized, especially its historical evolution and its decentralized and multi-agency management. The various modalities of the participation of small scale fishers in its management were illustrated by several case studies (Cahuita, Marino-Ballena, Palito, Tárcoles, Golfo Dulce). Second, fishing practices and socio-economic profile of small scale fishers of the three communities of Bahía Pavones (southeast of Golfo Dulce) were characterized. The small scale fishing activity is essentially based on eight species, of which the two main ones, Lutjanus gutattus (spotted rose snapper) and L. peru (Pacific red snapper) could be overexploited. The participation of small scale fishers to local organizations is significant despite a general lack of confidence towards these organizations. Finally, comparing the different case studies revealed the existence of eight key conditions for the development of a successful co-managed small scale fishery in Costa Rica. Within the Marine Responsible Fishing Area of the Golfo Dulce, it is the manipulation of small scale fishers by various user groups (in particular government and the tourism sector) that hinders the process of co-management.

Based on the constituition of JOC, ACO and PO in Santo Antonio and Imaculada Conceiçao churches, I tried to bring out the proposals and tendencies according to the military regime and the present workers. So, I noticed the plurality of existing positions and the ambiance of disputes in which are constituted the catholic workers movements, where different interpretations of work relations and catholic doctrine, for example, were debated and improved. The sources analysis showed that it is possible to observe a transformation in the movements throughout this period. We can notice the search for alternatives of solution for workers issues, those movements radicalize their speech and point to a construction of new strategies of fight and worker resistance. Declining an accidental view of the History, the construction of a new syndicalism and base syndicalism did not happen by chance, since the strikes of 1978, neither essentially starting from the Steelworkers Union of SA Bernardo. In the history reconstruction of the work class in Osasco, it is necessary to consider, beside other forces, the acting of catholic militants in the worker and syndical movement and to realize its influence on the authentic syndicalism, mainly in ABC paulista region / Esta dissertação visa à análise das relações entre militantes da Juventude Operária Católica (JOC), Ação Católica Operária (ACO), Frente Nacional do Trabalho (FNT) e Pastoral Operária (PO) e a classe operária, na cidade de Osasco, nas décadas de 1960-1970. Tendo como referência a constituição da JOC, ACO e PO nas igrejas Santo Antônio e Imaculada Conceição, procurei resgatar as propostas e tendências com relação ao regime militar e aos trabalhadores presentes. Notei, então, a pluralidade de posições existentes e o ambiente de disputas em que se constituíam os movimentos católicos operários, onde diferentes interpretações das relações de trabalho e da doutrina católica, por exemplo, debatiam-se e implementavam-se. A análise das fontes permitiu demonstrar que é possível observar uma transformação nos movimentos ao longo deste período. Observa-se que na busca de alternativas de soluções às questões operárias, estes movimentos radicalizaram o seu discurso e apontaram para a construção de novas estratégias de luta e resistência operária. Recusando uma visão acidental da História, a construção de um novo sindicalismo e de base não se deu por acaso, desde as greves de 1978, nem essencialmente partindo do Sindicato dos Metalúrgicos de São Bernardo. Na reconstrução da história da classe operária de Osasco, é preciso considerar, ao lado de outras forças, a atuação dos militantes católicos no movimento operário e sindical e perceber sua influência nos rumos do sindicalismo autêntico, especialmente no ABC paulista

原住民族長期生活於山村地區，有著特殊民族文化維繫個人或團體間長期的互動，惟日本時期沿襲迄今的保留地制度，無論是空間區位的選擇或增劃編地點的決定，原住民族毫無參與的餘地，導致無法妥善勘選區位適當的土地作為原住民保留地使用，進而使文化傳承、經濟生活所依賴的母土逐漸流失；近年來受國外原住民保留地經營管理成功案例的激勵及民族意識的興起下，原住民發起三次還我土地運動，而政府部門在增劃編的回應中，也認真的思索保留地興革的建議，遂在學者專家及原住民族菁英的討論過程，凝聚回復傳統產權共有舊制的共識。 　　憲法增修條文第十條第十二項對原住民族基本權的規範，含有「制度保障」之意涵，因此原住民族土地管理法規，是有提昇為法律位階之必要性，爰由內政部研定「原住民族土地開發管理條例」草案，刻正依法定程序送請立法院審議中。按該條例草案異於前之管理辦法者，在於增加了「原住民族保留區」的制度設計，新制在原住民族社會已有共識，惟尚缺乏個案研究的實證分析，因此難以辨別制度可能引發的後遺症，爰有本研究就桃源鄉進行個案分析驗證。 　　本研究以國外學者Elinor Ostrom在制度經濟學對共用資源共管機制的制度設計原則，來檢驗分析個案在保留區新制實施過程中，可能衍生的問題，以實地問卷訪談的方式進行調查；嗣經得知劃設原住民族保留區可以解決桃源鄉現存的保留地問題，而劃設地點以該鄉梅山村及寶山村最適宜，惟應建立一套劃設指標據以實施且應有相關配套措施，最後根據當地原住民的意見反應，證明集體決策理論觀點，適合運用在劃設原住民族保留區的決策過程。 　　此外，在後續研究的部分，本研究亦建議：桃源鄉小規模群體自主治理的資源利用方式，可否全面運用到保留區新制，有待與其他個案比較分析及探討，而欲達此政策目的，必須選定實驗區域，進行試驗及檢討，方得確保制度設計成為法律後，能夠彌補現行保留地措施肇致政府失靈與市場失靈的缺失。 / Taiwan indigenous people have lived in mountainous area for centuries. The interactions between their individuals and groups are regulated by specific cultures. However, the Reserved Land Institution began with Japan Colonist Era does not allow indigenous people to chose the place they live in by themselves. It made improper zoning. urthermore, it led to the land, which had supported their cultural and economic life lapsed gradually. In past twenty years, encouraged by the international indigenous movements and domestic ideology wakening, Taiwan indigenous people had held the Return My Land Demonstrations for three times. Government began to deliberate the reform of Indigenous Reserved Land Institution, and acquired conclusions after long-term discussion between government, scholars and indigenous elites. One of the conclusions is to revert to the traditional land tenure co-owning institution. 　　According to the Added Article of the Constitution (article 10, item 12) , this country has obligation to protect the basic rights of indigenous people with formal institutions. It means the Indigenous Reserved Land Developing and Managing Regulation needs to be promoted to a formal law. At this moment, The Legislative Yuan is deliberating the Indigenous Reserved Land Developing and Managing Law drafted by the Exclusive Yuan. A new designing named Reserved Area was made in it. This new designing was agreed by most of indigenous people. However, there is no empirical analysis to it and its side effect so far. Therefore, this research examined the Reserved Area Institution by case study in Taoyuan Township of Kaohsiung County. 　　The theoretical basis of this research is the institution designing principles of common pool resources self-governance, which addressed by Elinor Ostrom. Meanwhile, the investigation was processed by questionnaires. After the analysis, this research pointed that Indigenous Reserved Area Institution can solve the problems of Reserved land in Taoyuan Township now. The most proper locations of Indigenous Reserved Area are May-Shan and Pao-Shan villages. In farther step, it needs relative supporting measures and concrete area setting index. Beside, base on the responses of local residences, the research proved that Collective Action Theory is proper to be applied in the decision making process of setting the Indigenous Reserved Area. 　　In the end, the research suggested: the way people in Taoyuan Township governing their resource is not definitely proper to other indigenous groups. The precondition of implementing the new designing is to make more case tudies, compares and analysis. It is necessary to have small-scale experiments in advance. In the way, it can just correct the market failure and government failure caused by on going regulation when the new designing becomes a formal new law.

土地制度規範著對於土地的使用所引起的人與人之間相互認可的行為關係，對於制度起源的討論，往往認為制度具有降低成本、創造集體利益的功能，但由於制度主體的因素，制度則可能是國家對某一群體的剝削，例如日治時期將原住民土地收歸國有；由於制度安排的失當，很可能使得後續的發展陷入惡性的路徑依賴之中，例如民國五十五年的保留地私有化政策後原住民地權的快速流失。 　　一項近年的政府調查顯示，原住民保留地被非法使用、私下轉讓的情況日益嚴重，但同一時期的另一項研究卻又指出：原住民社會普遍傾向認為原住民保留地不得移轉給非原住民的限制不宜開放。從政治經濟的角度來說，保留地若朝向全面的私有化、開放原漢買賣，固然可以回應市場立即的需求，但交易過程中信息不完全、原住民經濟的弱勢等等外部效果卻不可能依靠市場機制加以解決，同時，可預見的原住民土地大量流失將和社會普遍認同的價值相違背；另一方面，保留地若朝向以國有化進行政府的干預，固然可以抑制自由買賣造成的原住民地權流失，但卻又和資源利用極佳化的市場邏輯相去甚遠而必須付出高額的成本，亦難以有效執行；從制度研究的眼光來看，現行的保留地制度正處於兩難下的制度失衡狀態。 　　在五年的反覆討論之後，內政部法規會於九十年一月十七號通過了「原住民族保留地開發管理條例草案」，該條例草案最大的特色是在所有權移轉限制下，增加了「原住民族保留區」的制度設計，在「原住民族保留區」中的土地所有權，得登記為原住民部落團體「共有」，土地的經營管理也將由部落團體來共同進行，這樣的政策所呈現是政府對於社會壓力和原住民土地困境的回應。然而，作為共有制實行的基礎，無論是在學理上或實證上，對於共有資源自主治理的探討都有尚待進一步充實的空間。 　　經過先期的調查和訪談，本研究選定新竹縣尖石鄉中三個公共資源自主治理的案例，並從制度經濟與集體選擇理論的架構，分析案例中人們如何建立自主性的組織，如何經由集體的選擇制定符合當地條件的公共資源治理規則，如何履行彼此的承諾並相互監督，以及如何避免陷入集體不理性的過度利用的悲劇，且對於案例中影響原住民部落採取資源共有和自主治理策略的因素加以探討。最後，評析內在制度的變遷及泰雅族傳統制度在現代的演化，以及公共資源自主管理在降低執行和監督成本、降低其外部效果、降低制度供給的成本等方面的制度優勢，並指出資源形式與共有範圍的關係、學習過程的重要、共有組織的作用是為共有制度有效運作的關鍵。 　　此外，在後續研究部份，本研究亦建議：理論上對於非以直接提取資源單位方式產生的利益分配問題、排他性技術的成本的雙重影響的探討；實證上對於集團移住後的原住民部落中共有組織的分析；政策上對共有組織「分級分類」原則的研議，皆值得作為後續進一步研究的課題。 / Institution about land rules the relationship, which is caused by land using and identified between people. According to the discussion of the beginning of institution, it can descend the cost of trade and make collective interesting. However, institutions can also be the means for a nation to exploit its people because of the subject of institution. The Nationalization of land, which is owned by aboriginal people in the time Japan governed Taiwan for instance. And, because of the improper arrangement of institution, the development may go in to a vicious path-dependence circle; the privatization policy in 1966 made the fast lapse of aboriginal land for example. 　　A recent investigation made by government shows that more and more aboriginal reserved-land was illegally sold and transferred in the black market. However, in the same time, another research appointed that most people in aboriginal society disagree the revocation of the limit that non-aboriginal cannot get the property of aboriginal reserved-land. In the view of political economics, if the property of aboriginal reserved-land was turn to entirely privatized, it can reply the immediate need market, but the external diseconomy such as incomplete information and the lower position of the aboriginal people can not be resolved by the market, and the following results that most of the aboriginal land property lapse will belie the general value identified by our society. On the other hand, if the property of aboriginal keeps on nationalized it can bate the lapse of the land property, but government has to pay high cost to belie the market logic hat resource should be optima used, and it will be difficult to administer. In the view of institutional study, the institution of aboriginal reserved-land is in a situation of inequilibrium. 　　After a long discussion lasted from more than five years, the Act Committee of Administer Department announced a proposed act for the development and administers of aboriginal reserved-land. The most particular part of this proposed act is the design of "aboriginal-reserved zone" and common land property. The total area of the aboriginal reserved zones was supposed to be 1.4 million acres, and the land property in the zones may belong to the whole settlement society. Such a policy is a positive reply to the social strait and the predicament of aboriginal society. However, being the base to exercise the common property institution, either the theoretical or the practical discussion of the "common pool resources self-governing" still needs to be completed. 　　A previous investigation and visiting, an Atayal county with three CPR self-governing cases was chosen in this approach. With a framework of institutional economics and collective act theory, this approach analyzed how people organized a self-governing organization, how a public choice was made to design the rules which are proper to local CPR situation, how people fulfill their obligation and supervise each other, how people avoid the tragic result o collective irrationality such as over using, furthermore, discuss the factor effect the CPR self-governing strategy .In the end, this approach discuss the change of internal institution and the evolution of Atayal tribes’ traditional institution in modern time, and the advantage of self-governing institution. Then, pointed out the relation between types of resources and areas of common property, the processes of learning, and the effects of organization are the key points to exercise the common property institution. 　　In addition, this approach suggested: in the theoretical aspect, the dispute caused by distribution of the interest that was not made by direct appropriation, the dual influence from the cost of exclusion technology. And, in the practical aspect, the principles to classify the self-governing organizations, can be the new problematic for further approach.

專利聯盟（patent pools）可以創造龐大的促進競爭效益，但是同時也可能產生妨礙競爭與創新之疑慮，若法律完全不對專利聯盟之運作進行規範，專利權人將得以利用專利聯盟制度作為提昇自己市場獨占力量，抑制市場競爭，甚至是濫用專利排他權的工具。為了畫下專利權人正當行使權利之界限，維護專利制度的政策目的，以規範專利聯盟所產生之專利權濫用問題，美國的法制上遂逐漸發展出以專利權濫用原則（patent misuse doctrine）與競爭法（即美國之反托拉斯法），對專利聯盟進行管制的結構。美國法上之專利權濫用原則創設之初係為了限制輔助侵權理論之適用，此理論最初與競爭法制並無交集，判斷的重點在於專利權人是否逾越其權限，之後隨著1988年美國專利法之修正，以及學理實務的改變，現今專利權濫用原則的認定已牽涉競爭法「合理原則」之判斷，然而，許多爭議也逐漸浮現，例如應如何判斷專利權人在專利聯盟中所為之限制競爭行為是否成立濫用，專利權濫用原則與競爭法之間之關係為何，甚至專利權濫用原則本身是否仍有必要存在，這些問題都尚待解決，因此現今正是對專利權濫用理論進行全面檢討之時機。 本文以下將針對專利聯盟所涉及之專利權濫用問題進行研究，對於實務上專利權人利用專利聯盟所進行之搭售、包裹授權、聯合訂價、競業禁止條款等行為進行觀察，並對其所涉及之專利權濫用問題進行初步分析。基於此一研究所獲得之基礎，本文將嘗試指出專利權濫用理論值得檢討之處，並指出專利權濫用理論兼具專利制度和競爭法制之特質，也反映了兩者間之衝突，其亦具有能夠與時俱進，以及反映專利制度政策公益之特質，因此仍有繼續存在價值。尤其係在專利聯盟成員利用彼此間競業禁止協議抑制新生替代性技術發展之情形，法院在適用競爭法合理原則時，往往因為專利聯盟所創造的促進競爭效益，以及新生技術未來發展的不確定性，而傾向認定此種契約條款為合法，忽略其所產生之抑制創新問題，此時即有適用專利權濫用原則之空間。此外，更可以考慮以我國民法第148條所規範之誠信原則與權利濫用原則作為將專利權濫用理論引入我國法之基礎，而在尚未引入以前，對於專利聯盟所涉及之專利權濫用問題，我國實務可以將美國法專利權濫用原則之理論基礎作為操作民法第148條、專利法第60條、公平交易法第18條及第19條以及其他相關規定時之指導原則。本文之意旨並非在完全以專利權濫用原則取代競爭法規範的角色，而係期待實務上應當設法對專利權濫用原則之價值進行重新評估，以賦予專利權濫用原則嶄新之生命，讓專利權濫用原則與競爭法共同形成一個完善、合理的專利權行使規範體系。 / Patent pool licensing can both create enormous pro-competitive and anti-competitive effects. Without legal intervention, the patentee would be able to manipulate the patent pool system as a mean to increase his own monopoly power, suppress competition in the market, and even misuse his patent exclusive power. In order to prevent the misuse of patent rights, protect patent policy and regulate patent misuse issues in patent pools, the U.S law system employs the “patent misuse doctrine” and competition law (antitrust law) to deal with the above issues. The patent misuse doctrine was initially designed to limit the overexpansion of the contributory infringement theory and has no relationship with competition law. The essential factor to constitute patent misuse is that the patentee extends the patent monopoly over the statutory scope of his patent right. Nevertheless, in pace with the Patent Misuse Reform Act of 1988 and the conversion of the legal practice, the patent misuse doctrine has begun to intertwine with competition law’s “rule of reason” analysis. Gradually, many disputes have emerged, such as how to determine whether the patentee’s conduct constitutes patent misuse in patent pools, what is the relationship between the patent misuse doctrine and competition law, and whether the patent misuse doctrine itself is necessary to exist. Therefore, it is high time to conduct a comprehensive review of the patent misuse theory. This article will provide insights to patent misuse issues in patent pool licensing, such as tie-in arrangement, package licensing, price fixing, non-competition agreements, etc, and review the theoretical basis of the patent misuse doctrine. This article will also submit that the patent misuse doctrine is a doctrine which has both the characteristics of patent law and competition law and can compromise the interests of these two areas of regulations. It can also reflect patent policy and grow and change with time. Therefore, it is a doctrine which should continue to exist. Particularly, in the situation which patent pool members use non-competition agreements to suppress the development of nascent substitute technologies, courts would often consider this kind of agreement to be legal because of the enormous pro-competitive effects created by the patent pool and the uncertainty of the future development of the nascent technology. At this moment, it is necessary to apply the patent misuse doctrine to deal with the problem. In addition, the principle of good faith which is encoded in article 148 of the civil code may be an appropriate medium to introduce the patent misuse doctrine into our legal system. Even if it is not yet introduced into our system, the patent misuse doctrine could be the guiding principle for our legal practitioners to apply article 148 of the civil code, article 60 of the patent act, article 18 and article 19 of the Fair Trade Act in order to deal with patent misuse issues in patent pool licensing. This article supports that the patent misuse doctrine should be refined and cooperate with competition law in order to form a complete regulation of patent misuse conducts, but it does not submit that current competition law should be entirely replaced by the patent misuse doctrine.

L'athérosclérose est une atteinte de la paroi des vaisseaux, qui détériore progressivement la circulation du sang à mesure qu'elle évolue. Les crises cardiaques et les attaques cérébrales qui sont les conséquences de cette maladie causent, dans les pays industrialisés, plus de décès que le cancer. L'angiographie est l'ensemble des techniques d'imagerie utilisées durant le diagnostic, le traitement, et le suivi de l'athérosclérose. Récemment, il a été montré que l'angiographie par Résonance Magnétique (ARM) avait un fort potentiel pour remplacer l'angiographie conventionnelle, invasive, par imagerie à rayons X. Cependant, pour exploiter toutes les informations apportées par cette modalité, il est nécessaire de mettre au point des méthodes plus objectives et plus reproductibles.<br />Cette thèse montre, à l'aide de deux applications, comment l'analyse d'images peut proposer une solution pour la définition et l'implémentation de ces méthodes. Premièrement, en utilisant la segmentation pour améliorer la visualisation de clichés d'ARM utilisant des produits de contraste du pool sanguin. Cette technique est aussi appliquée en angiographie scanner. Nous montrons que, en utilisant un algorithme issu de la théorie des graphes et de la logique floue, associé à une interaction limitée avec un utilisateur expert, nous pouvons simplifier la visualisation de structures 3D complexes comme les arbres vasculaires. Deuxièmement, nous proposons une méthodologie pour analyser la géométrie des artères en ARM corps entier. La ligne centrale des artères est extraite, et les propriétés géométriques de cette courbe 3D sont calculées, pour améliorer l'interprétation des angiogrammes. Ces techniques sont le point de départ d'une approche plus globale que la procédure conventionnelle d'évaluation de l'athérosclérose, dans l'espoir un jour d'utiliser ces méthodes pour un suivi systématique des maladies vasculaires.<br />Nous avons développé les méthodes que nous présentons dans le but qu'elles soient utilisées dans la pratique clinique. Cependant, elle peuvent potentiellement être utilisées pour d'autres applications de l'analyse d'images.

The Peruvian anchoveta fishery was for nearly 60 years characterized by the unsustainable dynamics of open access resource pools. This thesis investigates whether the 2009 Peruvian Legislative Decree 1084 on Individual Vessel Quotas (IVQ's) is an effective response to the industrial overcapacity and race-to-fish problems that threatened the environment before its implementation. It employs Common-Pool Resource theory to assess the impact of the new IVQ scheme on collective dynamics, and Ribot and Peluso's access theory (2009) to elucidate evolving power relations in the fishery. In this framework, DL1084 is evaluated as a regulatory instrument, as a lens on fisheries governance in Peru, and as a source of insight into how environmental impact serves in developing regulations of natural resource exploitation. A triangulated mixed-method design is employed: (1) a two-stream literature review of fisheries management and of the fishery's political ecology; (2) a quantitative analysis of daily state-published landings reports; and (3) seven in-depth intensive interviews with key actors in the fishery, conducted in Peru over two field-trips of approximately 2 months in total. Results indicate that although IVQ's supported existing trends towards large-scale economic efficiency and altered extreme competitive strategies previously associated with open access, fishing companies have built larger ships, favour bigger catches and still concentrate fishing effort around a given annual peak. Meanwhile, capacity has again increased in the unregulated artisanal fishery sector. DL1084 appears to reflect a broader process of growing private sector involvement in managing the fishery, made official by its institutionalization of market self-regulation. Ultimately, it evidences deep structure and capacity limitations in the state's ability to govern marine resources. The law was nevertheless seen as a landmark for the environmental legal process in Peru and an opportunity for reform. This thesis suggests that studying such legislations can provide insight into state identity and the evolving relationship between a nation and its geography. / Durante casi 60 años, la pesquería peruana de anchoveta estaba caracterizada por las dinámicas insostenibles de la explotación de recursos de propiedad común en situación de acceso abierto. Esta tesis investiga si el Decreto Legislativo Peruano 1084 (DL1084) sobre Límites Máximos de Captura por Embarcación (LMCE) es una respuesta efectiva a los problemas de sobrecapacidad industrial y de carrera por el recurso que amenazaban el ambiente antes de su aplicación en 2009. Se basa en la teoría de los Recursos de Propiedad Común (Common-Pool Resource theory) para evaluar el impacto del nuevo modelo de gestión por LMCE sobre las dinámicas colectivas, y en la teoría del Acceso de Ribot y Peluso (2009) para trazar la evolución de las relaciones de poder en la pesquería. En este marco, el DL1084 es evaluado como herramienta regulatoria, como lente sobre la gobernanza pesquera en el Perú y como reflejo del proceso por el cual el impacto ambiental sirve como base para el desarrollo de regulaciones sobre el acceso a recursos naturales. Sigue un diseño triangulado de métodos combinados: (1) una revisión de literatura en dos ramas de la gestión de pesquería como campo general y de la ecología política de la pesquería de anchoveta; (2) un análisis cuantitativo de los informes diarios de desembarques publicados por el estado (IMARPE); y (3) siete entrevistas intensivas de fondo con actores claves en la pesquería, realizadas en Perú durante dos visitas de aproximadamente dos meses en total. Los resultados indican que a pesar de que los LMCE soportaron una tendencia existente hacia una eficiencia económica de mayor escala y alteraron las estrategias competitivas extremas asociadas con el acceso abierto, las empresas pesqueras han construido embarcaciones más grandes, favorecen capturas de mayor tamaño y todavía concentran su esfuerzo pesquero alrededor de un pico anual de abundancia. En paralelo, ha aumentado la capacidad de captura en el sector artesanal, el cual no cuenta con límites de captura. El DL1084 aparece como parte de un proceso más general de creciente involucramiento del sector privado en el manejo de la pesquería, haciéndolo oficial por su misma institucionalización de la autorregulación del mercado. Por último, pone en evidencia profundas limitaciones de estructura y de capacidad en el estado en cuanto a cómo gobierna los recursos marinos. La ley ha sin embargo sido vista como un precedente importante para el proceso legislativo ambiental en el Perú así como una oportunidad para impulsar otras reformas. Esta tesis sugiere que el estudio de tales legislaciones puede ofrecer una mirada sobre los procesos de formación de la identidad de un estado y sobre la evolución de la relación entre una nación y su geografía.

La désinfection de l’eau de consommation et des piscines induit la formation de sous-produits (SPD) potentiellement nocifs pour la santé, parmi lesquels les trihalométhanes (THM), les acides haloacétiques (HAA) et les chloramines (CAM). La difficulté d’estimer l’exposition humaine à ces SPD empêche de cerner précisément les risques sanitaires possiblement associés (i.e., cancérigènes, reprotoxiques, irritatifs). Nos travaux s’articulent autour d’une méthodologie consistant à intégrer des données d’occurrence environnementales à des modèles toxicocinétiques à base physiologique (TCBP) pour améliorer les mesures de l’exposition aux SPD. Cette approche multidisciplinaire veut prendre en compte de manière aussi appropriée que possible les deux composantes majeures des variations de cette exposition : les variations spatio-temporelles des niveaux de contamination environnementale et l’impact des différences inter- et intra-individuelles sur les niveaux biologiques. Cette thèse, organisée en deux volets qui explorent chacun successivement des aspects environnemental et biologique de la problématique, vise à contribuer au développement de cette stratégie innovante d’estimation de l’exposition et, plus généralement, à des meilleures pratiques en la matière. Le premier volet de la thèse s’intéresse à l’exposition en milieu domestique (i.e., résultant de l’utilisation de l’eau potable au domicile) et est consacré au cas complexe des THM, les plus abondants et volatils des SPD, absorbables par ingestion mais aussi par inhalation et voie percutanée. Les articles I et II, constitutifs de ce volet, documentent spécifiquement la question des variations inter- et intra- journalières de présence des SPD en réseau et de leurs impacts sur les estimateurs de l’exposition biologique. Ils décrivent l’amplitude et la diversité des variations à court terme des niveaux environnementaux, présentent les difficultés à proposer une façon systématique et « épidémiologiquement » pratique de les modéliser et proposent, de manière originale, une évaluation des mésestimations, somme toute modestes, des mesures biologiques de l’exposition résultant de leurs non-prise en compte. Le deuxième volet de la thèse se penche sur l’exposition aux SPD en piscine, d’un intérêt grandissant au niveau international, et se restreint au cas jugé prioritaire des piscines publiques intérieures. Ce volet envisage, pour quantifier l’exposition dans ce contexte particulier, l’extension de l’approche méthodologique préconisée, élaborée originellement pour application dans un contexte domestique : d’abord, à travers une analyse approfondie des variations des niveaux de contamination (eau, air) des SPD en piscine en vue de les modéliser (article III); puis en examinant, dans le cas particulier du chloroforme, le THM le plus abondant, la possibilité d’utiliser la modélisation TCBP pour simuler des expositions en piscine (article IV). Les résultats mettent notamment en évidence la difficulté d’appréhender précisément la contamination environnementale autrement que par un échantillonnage in situ tandis que la modélisation TCBP apparait, sur le plan toxicologique, comme l’outil le plus pertinent à ce jour, notamment au regard des autres approches existantes, mais qu’il convient d’améliorer pour mieux prédire les niveaux d’exposition biologique. Finalement, ces travaux illustrent la pertinence et la nécessité d’une approche multidisciplinaire et intégratrice et suggère, sur cette base, les pistes à explorer en priorité pour mieux évaluer l’exposition aux SPD et, in fine, cerner véritablement les risques sanitaires qui en résultent. / Disinfection of drinking and swimming pool waters disinfection is unavoidable but induces the formation of by-products (DBPs), such as trihalomethanes (THMs), haloacetic acids (HAAs) and chloramines (CAMs), that could be harmful to human health. The still challenging DBP exposure assessment prevent their suspected adverse effects (i.e., cancers, adverse pregnancy outcomes, irritations) to be clearly established. A methodology has been conceptualized which consists of integrating environmental occurrence data with physiologically based toxicokinetic (PBTK) modeling to improve DBP exposure assessment. It was designed to allow both spatial and temporal variations of the environmental contamination and the biological impacts of between- and within- individual differences to be accounted for. This thesis comprised of two parts. Each one investigates successively both environmental and biological aspects. The objective is to contribute to the development of an innovative integrated strategy and to the definition of best practices for DBP exposure assessment. The first part of the thesis, comprising papers I and II, focuses on household exposure (i.e., resulting from drinking water use at home) and on THMs, the most abundant and volatile DBPs that can be absorbed not only by ingestion but also by inhalation and dermal absorption. These two papers investigate particularly the short-term (day-to-day and within-day) variations of THM levels in the drinking water and then their impact on the internal exposure indicators. They described the amplitudes and the diversity of the environmental variations, failed to model them in a systematic and practical way for epidemiological purposes but assessed, for the first time, their impacts on the predicted biological levels which appeared quite low. The second part concerns the exposure to DBPs in swimming pool which is of a growing international interest. Only the allegedly worrying case of public indoor swimming pool was regarded. This section focuses on the feasibility of using the previously mentioned approach, which was first designed for dealing with household exposure, for DBP exposure assessment in swimming pools. First, Paper III investigated the occurrence and spatial and temporal variations of DBPs in both water and air of swimming pools to model them. Focusing on chloroform, the most abundant THM, Paper IV examined the ability and reliability of PBTK modeling to simulate various swimming pool exposure events and predict the resulting biological levels in individuals. The results show, among other things, the difficulty of explaining precisely the environmental contamination and point out the necessity to carry out a minimal in situ sampling to monitor the environmental levels of DBPs. Compared to other approaches, PBTK modeling is a powerful but still to be improved tool for predicting swimming pool exposure. Eventually, these works underline the relevance and the necessity of a multidisciplinary and integrating approach for better estimating exposure to DBPs and therefore health risks. Further issues that should be addressed are recommended.

An understanding of compartment fire behaviour is important for fire protection engineers. For design purposes, whether to use a prescriptive code or performance based design, life safety and property protection issues are required to be assessed. The use of design fires in computer modelling is the general method to determine fire safety. However these computer models are generally limited to the input of one design fire, with consideration of the complex interaction between fuel packages and the compartment environment being simplified. Of particular interest is the Heat Release Rate, HRR, as this is the commonly prescribed design parameter for fire modelling. If the HRR is not accurate then it can be subsequently argued that the design scenario may be flawed. Therefore the selection of the most appropriate fire design scenario is critical, and an increased level of understanding of compartment behaviour is an invaluable aid to fire engineering assumptions. This thesis details an experimental study to enhance the understanding of the impact and interaction that the size and location of pool fires within an enclosure have upon the compartment fire behaviour. Thirty four experiments were conducted in a reduced scale compartment (½ height) with dimensions of 3.6m long by 2.4m wide by 1.2m high using five typical ventilation geometries (fully open, soffit, door, window and small window). Heptane pool fires were used, located in permutations of three evenly distributed locations within the compartment (rear, centre and front) as well as larger equivalent area pans located only in the centre. This thesis describes the experimental development, setup and results of the experimental study. To assist in the classification of compartment fire behaviour during the experiments, a ‘phi’ meter was developed to measure the time dependent equivalence ratio. The phi meter was developed and configured to measure O₂, CO₂ and CO. The background development, calibration, and experimental results are reported. A review of compartment fire modelling using Fire Dynamics Simulator, has also been completed and the results discussed. The results of this experimental study were found to have significant implications for Fire Safety Engineering in that the size of the fire is not as significant as the location of the fire. The effect of a fire near the vent opening was found to have a significant impact on compartment fire behaviour with the vent located fuel source increasing the total compartment heat release rate by a factor of 1.7 to that of a centrally placed pool fire of the same total fuel area. The assumption that a fire located in the centre of the room provides for the highest heat release rate is not valid for post-flashover compartment fires. The phi meter was found to provide good agreement with the equivalence ratio calculated from total compartment mass loss rates, and the results of FDS modelling indicate that the use of the model in its current form can not be applied to complex pool fire geometries.

The thesis is focused on the topic of virtual cryptocurrency Bitcoin. The theoretical part is divided into several chapters. First of all, there is a chapter containing basic information about the currency's history, its development to the present, as well as principles of operation of this currency. Because it is a currency based on cryptographic principles next chapter summarizing cryptographic techniques, which is necessary to know for subsequent analysis of this currency. In other parts is elaborated a detailed analysis of the principles of Bitcoin. The main point of this analysis is a system of transactions, decentralized history, then joining the transactions into blocks and in the end creating blockchain. It also explains the principle of P2P networks. The practical part of this work focuses on the analysis and design of payment applications for mobile devices. There used open-source libraries such BitcoinJ. The application is developed in Java programming language with plugin for portable devices, which work under the operating system Android. For the purposes of analysis and design of graphical user interface is used UML diagrams. The specification of the UML diagrams was utilized by freely available graphics software and the result is also included in this work.
