En analysant les évolutions récentes de l'industrie du médicament, cette thèse apporte de nouveaux éléments, théoriques et empiriques, sur les mécanismes de transformation des industries de hautes technologies. Nous cherchons à comprendre pourquoi l'introduction de discontinuités technologiques ne conduit pas forcément au changement de l'industrie, et comment la logique dominante peut être remise en question. Pour répondre à cette problématique, nous utilisons une approche qualitative. Nous interrogeons des experts de l'industrie du médicament, et analysons onze études de cas d'entreprises de biotechnologies et de bioinformatique. Notre première contribution théorique est de proposer le concept de logique dominante pour compléter les travaux sur le cycle de vie des industries. Nous argumentons que les discontinuités technologiques sont une condition nécessaire, mais pas suffisante, du changement de phase d'une industrie. Le concept de logique dominante permet de prendre en compte les schémas généraux de création et de capture de valeur qui contraignent la stratégie des firmes évoluant dans l'industrie. Notre seconde contribution théorique est d'identifier quatre mécanismes de remise en cause de la logique dominante d'une industrie :nouvelles propositions de valeur, alliances avec de grandes entreprises d'autres industries, orchestration de réseaux, et portefeuilles de business models. Notre troisième contribution est managériale. Nous proposons un outil de la conception de la stratégie d'entreprise afin d'articuler promesses et risques, moyen et long terme. Enfin, notre quatrième contribution s'adresse aux managers et dirigeants de l'industrie du médicament. Nous leur suggérons quatre pistes de réflexion pour concevoir la stratégie de leur entreprise. / In analyzing recent developments in the drug industry, this thesis brings new elements, both theoretical and empirical, on mechanisms for the transformation of high-technology industries. We seek to understand why the introduction of technological discontinuities does not necessarily lead to change in the industry and on how the dominant logic can be questioned. To address this problem, we used a qualitative approach. We interviewed drug industry experts, and analyzed eleven case studies of biotechnology and bioinformatics companies. Our first theoretical contribution is to propose the concept of dominant logic to complete research on industry life cycle, where we argue that technological discontinuities are a necessary, but not sufficient, condition to change the industry. The concept of dominant logic allows taking into account the general schemes of value creation and value capture that constrain the strategies of the firms that are in the industry. Our second theoretical contribution is to identify four mechanisms of challenge to the industry's dominant logic: new value propositions, alliances with large diversifying entrants, orchestration of networks, and portfolios of business models. Our third contribution is managerial. We offer a tool for the design of corporate strategy. This tool allows articulating promises and risks, medium and long term. Finally, our fourth contribution addresses managers and leaders of the drug industry. We suggest four ways of thinking about the design of their corporate strategies.

[pt] A dissertação visa relatar e analisar o fracasso do processo de paz realizado na Colômbia, durante o governo do presidente Andrés Pastrana, entre os anos de 1998 e 2002. A realidade local constituía-se num drama humanitário cuja solução se mostrava contrária à sustentação de mitos como o de uma democracia política estável ou o da pobreza como a principal causa da violência. O firme desígnio de resolver pacificamente a luta armada exigia que se levasse em consideração a natureza complexa e instável do Estado, a identidade dos atores armados, a realidade do agravamento da crise social e a difícil conciliação entre os interesses internos e externos. O empreendimento conduzido pelo presidente Andrés Pastrana era objeto da área de estudos de resolução pacífica de conflitos, cujas lentes conceituais foram as escolhidas como ferramenta para leitura e interpretação dos fatos. Esta literatura lida com o contexto sócio-político no qual se desenvolvia o enfrentamento armado, abrangendo as várias características específicas deste contexto. Ela preconizava o reconhecimento mútuo e a flexibilização das exigências, para que a negociação apresentasse avanços. O colapso do processo de paz colombiano, entre outros aspectos, tornou evidentes os obstáculos para a transformação do conflito. Sequer conseguiu-se fazer que os dois lados presentes à negociação renunciassem ao uso das armas. Decorridos aproximadamente quatro anos de negociação entre o governo e as FARC, os esforços não lograram substituir uma histórica, vivaz e destrutiva experiência por outra, construtiva e benéfica, a qual poderia ter se sobressaído na eventual assinatura de um acordo de paz. / [en] This essay is an account and an analysis of the failure of the Colombian peace process that took place during the presidential mandate of Andrés Pastrana from 1998 through 2002. The local reality actually became an humanitarian crisis whose solution necessarily involved abandoning shattered myths such as that of a stable democracy or that of poverty as the main root of endemic violence. The strong will to solve the armed conflict in a peaceful way has lead to reflection on the complex and unstable nature of the Colombian state, the true character of the quarrelling actors, the deepening of the social crisis and the tricky conciliation between internal and external interests. President Pastrana´s initiative falls into the area of studies of peaceful conflict resolution. The reading and interpretation of the facts will therefore be undertaken through the lenses of the literature on peaceful conflict resolution. That literature deals with the issue of the socioeconomic context in which the armed struggles occur, including its specifics. It also recommends mutual political recognition among parties and increasingly flexible demands in order to spur the smooth advance of the negotiation. The ultimate collapse of the Colombian peace process exposed the multiple obstacles to a solution to the civil war. It was not even possible to persuade either party to drop weapons. After four years of negotiations between the government and the Revolutionary Armed Forces of Colombia had passed, all these efforts were not enough to replace an ago-old, historical, and destructive social experience for a new, constructive, and beneficial experience. Such a new reality could have been possible if a peace accord had been reached.

The use and trade in medicinal plant products in South Africa is a cultivating sector of rural development. In order to conserve these plants and develop sustainable production, policies to promote domestication have been adopted. However, users view cultivated plants with scepticism. The key for policy makers is to understand how users respond to scarcity of species and whether domestication can be a solution. The main purpose of the study is to give an overview of variables that influence the rate of adoption of medicinal plant gardens. The last discussion will investigate whether domestication of species is an appropriate solution to conservation, or whether the intervention should be promoted as a local economic development option. The research took the form of a case study approach focusing on a specific area, with participatory and qualitative phases providing the basis for a semi-structured interview schedule, designed to assess the healer's acceptability of medicinal plant gardens, their comparative perception of cultivated and collected plants in their natural habitat/environment, and constraints in the establishment of medicinal plant gardens. Results indicated that:<li> The type of healer influences acceptability of medicinal plant gardens; •Healers use medicinal plant gardens to supply urban demand and provide income; • Healer and client perceptions of medicinal plant potency influence acceptability of cultivated plants; •Type of healer influences the environment in which species are collected. • Ancestral belief system forms an integral component of healers behavioural pattern.</li> The study concludes that:<li> Local scarcity of medicinal plants alone does not stimulate demand for nurseries; • Rituals associated with some treatments influence collection, storage and cultivation patterns; • Policy makers also need to promote domestication for commercial production and to investigate alternatives for propagating the population of some plant species in their natural habitat/environment to cater for specific needs of healers and • Interview responses, although useful, cannot always be taken at face value<//i>. / Dissertation (M Inst Agrar ( Agricultural Extension))--University of Pretoria, 2005. / Agricultural Economics, Extension and Rural Development / unrestricted

[pt] O Triângulo Norte da América Central é composto por El Salvador, Honduras e Guatemala. Esses países compartilham um histórico de desigualdades socioeconômicas, violência e intervenções estrangeiras em seus territórios. Intensos fluxos emigratórios são registrados nesses países, com seus nacionais buscando chegar aos Estados Unidos percorrendo o território mexicano, razão pela qual consideramos esses quatro países como uma região de emigração, devido aos fluxos neles originados e atravessados. Essas migrações geralmente ocorrem de maneira forçada e em fluxos maciços. Consoante à mobilidade, ocorre um processo de contenção desses migrantes por parte dos Estados Unidos, que desenvolve mecanismos físicos e políticos para impedir a entrada dessas pessoas em seu território, além de imporem políticas migratórias e fronteiriças ao México e aos países do Triângulo Norte da América Central para impedirem os fluxos de chegarem em sua fronteira. Assim sendo, percebemos esses quatro países como uma região de fronteira que se traduz em região de i-mobilidade migratória, pois nela ocorrem dois processos concomitantes, o de trânsito e o de controle do mesmo. Nesta dissertação, investigamos a violência como elemento deflagrador dessas migrações e como ela atinge os sujeitos migrantes ao longo de seu percurso à Terra Prometida, os Estados Unidos. Analisaremos as migrações ocorridas entre 2018 e 2021, com foco nas caravanas de migrantes centro-americanos, apresentando as inovações de sua organização e o perfil demográfico daqueles que as integraram, bem como as medidas tomadas pelos Estados Unidos e México para impedir essa mobilidade. / [en] The Northern Triangle of Central America is composed by El Salvador, Honduras and Guatemala. These countries share a history of socioeconomic inequalities, violence, and foreign interventions in their territories. Intense emigration flows are recorded in these countries, with their nationals seeking to reach the United States by traveling through Mexican territory, in what we consider these four countries as a region of emigration, due to the flows originating and crossing through them. These migrations usually occur in a forced way and in massive flows. The United States develops physical and political mechanisms to prevent these people from entering its territory and imposes migration and border policies to Mexico and to the countries of the Northern Triangle of Central America to prevent the flows from reaching its borders. Thus, we perceive these four countries as a border region that translates into a region of migratory i-mobility, because two concomitant processes occur there, that of transit and that of control of it. In this dissertation, we investigate violence as a triggering element of these migrations and how it affects the migrant subjects along their journey to the Promised Land, the United States. We will analyze the migrations that occurred between 2018 and 2021, focusing on the Central American migrant caravans, presenting the innovations of their organization and the demographic profile of those who integrated them, as well as the measures taken by the United States and Mexico to prevent this mobility.
