Spacepower and space warfare : the continuation of terran politics by other means

Bowen, Bleddyn Endaf January 2015 (has links)
Space technologies and the tools of space warfare are proliferating across Earth. The use of spacepower in conflict necessitates strategic thinking. Strategic theory can guide and improve strategic thought about outer space. Drawing on strategic theory, this thesis develops a spacepower theory in the next step of a collective theory-making effort about warfare in the Space Age. This spacepower theory is based on seven distinct, complementary, and interacting propositions that aim to shift the debate of spacepower away from space weaponisation and the Revolution in Military Affairs (RMA), and towards a more holistic view of the vast possibilities granted by spacepower. This spacepower theory proposes that space warfare only has meaning in so far it works towards the command of space; that the command of space is about manipulating celestial lines of communication; that spacepower in Earth orbit is a place to conduct strategic manoeuvres to influence the wider war and grand strategic goals; and that the command of space can have direct meaning for battlefield success through its dispersing effects. The theory is based on three major strategic analogies from terrestrial strategic theory and experience. First, space warfare is a continuation of terrestrial politics. Second, space is like the sea in its most basic concepts. Third, Earth orbit is like a coastal region. The contributions of this work are a theory that assists the individual’s education on warfare in the Space Age that takes emphasis away from space-based weaponry and the RMA, and a treatise that demonstrates and encourages a pedagogical method of analysis in strategic studies. This has tentative implications for wider discussions of astropolitics in International Relations (IR) as well. IR will continue in its usefulness in the cosmos, while Terran IR today must account for the realities of the Space Age.

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / This research seeks to portray and analyze the process of internationalization and the international cooperation of higher education in Brazil, since 2010 mainly, when it is inaugurated the Federal University of Latin American Integration (UNILA) in the city Foz do IguaÃu-PR, with regional integration proposal, through the teaching of Latin American countries and the Caribbean, and also that year it was founded the University of International Integration of African Brazilian Lusophone (UNILAB) having an integrative proposal between the nations that make up the Community of Portuguese Language Countries (CPLC), comprising Angola, Cape Verde, Guinea Bissau, Mozambique, Portugal, Sao Tome and Principe, East Timor, Equatorial Guinea and Brazil in the city of RedenÃÃo-CE. With these universities Brazil presents to the world, an internationalization project by higher education, through a cooperation project called South, with a promise to ensure the humanistic, scientific and technological knowledge and the partnership in South Atlantic area, which appears as an area of political interest to Brazil for some time. The main aim of this research is to understand the strategies for internationalization of higher education in a globalized world, and to know how Brazil has been acting in this process. In this study we used as methodological basis, a descriptive exploratory survey on the perception of internationalization of higher education, from international universities in Brazil, and geopolitical and economic interests in Latin America and Africa. We interviewed teachers, administrative staff, students and people from the society, to get a sense of social actors involved and we based on literary scholars authors on the subject. We seek to understand in this study, how educational policies may interfere with power relations and local arrangements, allowing greater regional role in a globalized world. We obtained as results that the challenges are many, internally and externally, in the institution and in the municipalities involved, but it is geographically feasible and relevant for educational policies in the South Atlantic zone. / Essa pesquisa procura apresentar e analisar o processo de internacionalizaÃÃo e a cooperaÃÃo internacional do ensino superior no Brasil a partir principalmente do ano de 2010, quando à inaugurada a Universidade Federal da IntegraÃÃo Latino Americana (UNILA) na cidade de Foz do IguaÃu-PR, com a proposta de integraÃÃo regional, atravÃs do ensino dos paÃses da AmÃrica Latina e Caribe e tambÃm nesse ano foi fundada a Universidade da IntegraÃÃo Internacional da Lusofonia Afro-Brasileira (UNILAB) possuindo uma proposta integradora, entre as naÃÃes que compÃem a Comunidade dos PaÃses de LÃngua Portuguesa (CPLP), formada por: Angola, Cabo Verde, GuinÃ-Bissau, MoÃambique, Portugal, SÃo Tomà e PrÃncipe, Timor-Leste, Guinà Equatorial e Brasil na cidade de RedenÃÃo-CE. Com essas universidades o Brasil apresenta ao mundo um projeto de internacionalizaÃÃo, por meio do ensino superior, atravÃs de uma proposta de cooperaÃÃo denominada Sul-Sul, com a promessa de garantir o conhecimento humanÃstico, cientÃfico, tecnolÃgico e a cooperaÃÃo solidÃria na zona do AtlÃntico Sul, que se apresenta como Ãrea de interesse polÃtico para o Brasil hà algum tempo. O principal objetivo dessa pesquisa à compreender as estratÃgias para a internacionalizaÃÃo do ensino superior em um mundo globalizado, e como o Brasil vem agindo nesse processo. Nesse estudo utilizamos como embasamento metodolÃgico um levantamento descritivo e exploratÃrio sobre a percepÃÃo da internacionalizaÃÃo do ensino superior, a partir das universidades de integraÃÃo internacional no Brasil, e os interesses geopolÃticos e econÃmicos na AmÃrica Latina e na Ãfrica. Entrevistamos professores, tÃcnicos administrativos, alunos e pessoas da prÃpria sociedade, para obter uma visÃo dos atores sociais envolvidos e nos embasamos na literatura de autores estudiosos no assunto. Procuramos entender nesse estudo, como polÃticas educacionais podem interferir nas relaÃÃes de poder e nos arranjos locais, possibilitando uma maior atuaÃÃo regional em um mundo globalizado. Obtivemos como resultados que os desafios sÃo muitos, a nÃvel interno e externo, na prÃpria instituiÃÃo e nos municÃpios envolvidos, porÃm à geograficamente viÃvel e de relevÃncia para as polÃticas educacionais na zona do AtlÃntico Sul.

C0-Semigroup Methods for Delay Equations

Stein, Martin 06 November 2008 (has links) (PDF)
In der Dissertation werden Werkzeuge zur Analyse von Wohlgestelltheit und Asymptotik von Integro-Differential- und Verzögerungsgleichungen entwickelt. Im ersten Teil der Arbeit (Kapitel 1 und 2) werden Methoden zur Bestimmung der Modulhalbgruppe (kleinste dominierende C0-Halbgruppe) einer C0-Halbgruppe zur Verfügung gestellt, die unter anderem auf Volterra-Halbgruppen (die aus Integro-Differentialgleichungen hervorgehen) und Evolutionshalbgruppen (Rückkopplungsgleichungen mit Zeitverzögerung, Transport in Netzwerken) angewendet werden. Im Mittelpunkt des zweiten Teils (Kapitel 3 und 4) steht ein Integro-Differentialgleichungstyp, der Schwingungsphänomene von Tragswerksflächen im Unterschallbereich beschreibt. Das besondere dieser Gleichung ist das Auftreten der Zeitableitung der gesuchten Funktion im Integralterm. Es werden eine Reihe von Wohlgestelltheitskriterien hergeleitet, welche Wohlgestelltheit der Gleichung liefern, ohne das es möglich ist, durch partielle Integration die Zeitableitung im Integralterm zu beseitigen und dadurch die Gleichung auf einen bekannten Integro-Differentialgleichungstyp zurückzuführen. Die entwickelten Methoden eignen sich auch für die Herleitung neuer Wohlgestelltheitskriterien für andere Verzögerungsgleichungen. Entsprechende Resultate werden in Kapitel 4 hergeleitet. / In the dissertation tools for the analysis of well-posedness and asymptotic behaviour of integro-differential equations and delay equations are developed. In the first part (chapter 1 and 2) methods for the determination of the modulus semigroup (smallest dominating C0-semigroup) of a C0-semigroup are provided and applied to various examples such as Volterra semigroups and evolution semigroups and transport evolution equations in networks. The main interest of the second part (chapter 3 and 4) is a type of an integro-differential equation which occurs in the modelling of the flutter of airfoils at subsonic speed. The remarkable property of the equation is the time derivative of the sought function in the integral term. A number of well-posedness criteria are proved for which integration by parts is not possible. The developed methods are also suitable for the derivation of new well-posedness results for other delay semigroups. Corresponding criteria are presented in chapter 4.

Deliberative peacebuilding in East Timor and Somaliland

Nakagawa, Yoshito January 2016 (has links)
This thesis is a theoretical and empirical inquiry into ‘deliberative peacebuilding’, seeking to explain the ‘failures’ and ‘successes’ of peacebuilding in East Timor and Somaliland. While warfare has increased globally since the end of the Cold War, the UN has made efforts to build peace (e.g. Boutros-Ghali 1992). While peacebuilding has become an internationally applied set of ideas and practices, one of the theoretical gaps is deliberation. This research thus conceptualises ‘deliberative peacebuilding’, and associates this with peacebuilding in the non-Western, post-colonial, and (post-)conflict context. This research identified East Timor and Somaliland as its case studies. Despite similarity in the ‘legitimation problem’ with vertical (state-society) and horizontal (‘modernity’-‘tradition’) inequalities/differences based upon cultural and historical backgrounds, East Timor and Somaliland undertook different approaches in a decade after the end of their civil wars. While East Timor accepted UN peace operations, Somaliland rejected them. Yet both experienced similar transitions to make political order between ‘failure’ (political de-legitimation/societal dissent) and ‘success’ (political legitimation/societal consent).Accordingly, this thesis poses two questions: 1) what caused the UN to have ‘failed’ (to prevent the ‘crisis’ from recurring in 2006) in East Timor, and 2) what caused East Timor and Somaliland to have experienced ‘equifinality’ (making similar progress along different paths) in building peace (in East Timor from 1999 to 2012 and in Somaliland from 1991 to 2005). Findings, among others, include different paths in transition: a ‘hybrid’ path with external intervention in East Timor and an ‘agonistic’ path without it in Somaliland. Asymmetry in power relations urged deliberative agencies to address the ‘legitimation problem’ differently.

Duality theory for p-th power factorable operators and kernel operators

Galdames Bravo, Orlando Eduardo 29 July 2013 (has links)
El presente trabajo está dedicado al análisis de una clase particular de operadores (lineales y continuos) entre espacios de Banach de funciones. El objetivo es avanzar en la teoría de los llamados operadores factorizables a la p-potencia analizando todos los aspectos de la dualidad. Esta clase de operadores ha demostrado ser de utilidad tanto en la teoría de factorización de operadores sobre espacios de Banach de funciones (teoría de Maurey-Rosenthal) como en el Análisis Armónico (dominios óptimos de la transformada de Fourier y operadores de convolución). A ¿n de desarrollar esta teoría de dualidad y sus aplicaciones, se de¿ne y estudia una nueva clase de operadores con propiedades de extensión que involucran al operador y a su adjunto. Ésta es la familia de operadores factorizables a la (p,q)- potencia, 1 · p,q Ç 1, y pueden caracterizarse mediante un esquema de factorización a través del espacio de p-potencias del dominio y el dual del espacio de q-potencias del dual del codominio. También se obtiene una equivalencia mediante un diagrama de factorización a través de espacios L p (m) y L q (n) 0 , donde m y n son medidas vectoriales adecuadas y ésta será nuestra principal herramienta. Para esta construcción resultan necesarios algunos resultados preliminares relativos a las p-potencias de los espacios de Banach de funciones que intervienen y que también se estudian. Con estos útiles se dan algunos resultados para caracterizar el rango óptimo ¿el menor espacio de Banach de funciones en el que puede tomar valores el operador¿ para operadores que van de un espacio de Banach a un espacio de Banach de funciones. Además, se desarrolla y presenta formalmente la idea de factorización óptima de un operador que optimiza una factorización previa, en términos del diagrama que debe satisfacer un operador factorizable a su (p,q)-potencia. Todos estos resultados extienden los actuales cálculos del dominio óptimo mediante medidas vectoriales para operadores sobre espacios de Banach de funciones. Dichos cálculos han dado resultados relevantes en diversas áreas del análisis matemático mediante una descripción del mayor espacio de Banach de funciones al cual, operadores relevantes ¿como la transformada de Fourier o el operador de Hardy¿ se pueden extender. La teoría se aplica para encontrar nuevos resultados en determinados campos: como la teoría de interpolación de operadores entre espacios de Banach de funciones, los operadores de núcleo y en particular, la transformada de Laplace. / Galdames Bravo, OE.

"Potápějící se ostrovy" a Rada bezpečnosti OSN / "Sinking Islands" and the United Nations Security Council

Bruner, Tomáš January 2019 (has links)
Certain Small Island Developing States (hereinafter the "SIDS") such as Kiribati or Tuvalu are often incorrectly called "sinking islands" because their highest points are located just a few meters above the sea level. Sea level rise may turn their territories to uninhabitable land gradually disappearing beneath the tide. Worsening of the environmental conditions causes internal displacement, migration and other problems. SIDS repeatedly brought their plight to the United Nations Security Council (the "UNSC") during its meetings in 2007, 2011, 2015, 2018 and 2019. They demanded that the UNSC should deal with their situation as a potential security issue and safeguard more equal distribution of environmental security risks and costs. During the UNSC negotiations, various states attempted to interpret and re-interpreted the UNSC mandate in order to suit their interests. The representatives of SIDS suggested that the UNSC should be a body based on the principles of distributive justice decision-making and thus safeguard fairer sharing of threats and burdens, including those of environmental character. The rapidly developing states strongly opposed; they implicitly claimed that the UNSC should be based rather on the principles of commutative justice, i.e. decide in strictly given situations of violations of...
