In this thesis, we study the phenomenology of selected observables in the context of the Randall-Sundrum scenario of a compactified warpedrnextra dimension. Gauge and matter fields are assumed to live in the whole five-dimensional space-time, while the Higgs sector is rnlocalized on the infrared boundary. An effective four-dimensional description is obtained via Kaluza-Klein decomposition of the five dimensionalrnquantum fields. The symmetry breaking effects due to the Higgs sector are treated exactly, and the decomposition of the theory is performedrnin a covariant way. We develop a formalism, which allows for a straight-forward generalization to scenarios with an extended gauge group comparedrnto the Standard Model of elementary particle physics. As an application, we study the so-called custodial Randall-Sundrum model and compare the resultsrnto that of the original formulation. rnWe present predictions for electroweak precision observables, the Higgs production cross section at the LHC, the forward-backward asymmetryrnin top-antitop production at the Tevatron, as well as the width difference, the CP-violating phase, and the semileptonic CP asymmetry in B_s decays.

In this thesis, the phenomenology of the Randall-Sundrum setup is investigated. In this context models with and without an enlarged SU(2)_L x SU(2)_R x U(1)_X x P_{LR} gauge symmetry, which removes corrections to the T parameter and to the Z b_L \bar b_L coupling, are compared with each other. The Kaluza-Klein decomposition is formulated within the mass basis, which allows for a clear understanding of various model-specific features. A complete discussion of tree-level flavor-changing effects is presented. Exact expressions for five dimensional propagators are derived, including Yukawa interactions that mediate flavor-off-diagonal transitions. The symmetry that reduces the corrections to the left-handed Z b \bar b coupling is analyzed in detail. In the literature, Randall-Sundrum models have been used to address the measured anomaly in the t \bar t forward-backward asymmetry. However, it will be shown that this is not possible within a natural approach to flavor. The rare decays t \to cZ and t \to ch are investigated, where in particular the latter could be observed at the LHC. A calculation of \Gamma_{12}^{B_s} in the presence of new physics is presented. It is shown that the Randall-Sundrum setup allows for an improved agreement with measurements of A_{SL}^s, S_{\psi\phi}, and \Delta\Gamma_s. For the first time, a complete one-loop calculation of all relevant Higgs-boson production and decay channels in the custodial Randall-Sundrum setup is performed, revealing a sensitivity to large new-physics scales at the LHC.

The aims of the dissertation are to find the right description of the structure of perceptual experience and to explore the ways in which the structure of the body might serve to explain it. In the first two parts, I articulate and defend the claim that perceptual experience seems direct and the claim that its objects seem real. I defend these claims as integral parts of a coherent metaphysically neutral conception of perceptual experience. Sense-datum theorists, certain influential perceptual psychologists, and early modern philosophers (most notably Berkeley) all disputed the claim that perceptual experience seems direct. In Part I, I argue that the grounds on which they did so were poor. The aim is then, in Part II, to give a proper appreciation of the distinctive intentionality of perceptual experience whilst remaining metaphysically neutral. I do so by drawing on the early work of Edmund Husserl, providing a characterisation of the perceptual experience of objects as real, qua mind-independent particulars. In Part III, I explore two possible explanations of the structure characterising the intentionality of perceptual experience, both of which accord a distinctive explanatory role to the body. On one account, perceptual experience is structured by an implicit pre-reflective consciousness of oneself as a body engaged in perceptual activity. An alternative account makes no appeal to the metaphysically laden concept of a bodily self. It seeks to explain the structure of perceptual experience by appeal to anticipation of the structural constraints of the body. I develop this alternative by highlighting the conceptual and empirical basis for the idea that a first-order structural affordance relation holds between a bodily agent and certain properties of its body. I then close with a discussion of the shared background assumptions that ought to inform disputes over whether the body itself (in addition to its representation) ought to serve as an explanans in such an account.

Die vorliegende Arbeit setzt sich zum Ziel, die gesellschaftliche Relevanz der Praktischen Philosophie vor allem für die beiden Strömungen der Philosophischen Praxis als Beratung und der Fachdidaktik der Philosophie und Ethik aufzuzeigen.rnDabei sollen die umfassenden Themenfelder der philosophischen Praxis in einen systematischen Zusammenhang gebracht und auf die Grundfragen der Praktischen Philosophie und ihre Methoden zurückgeführt werden.rnZentraler Bestandteil dieser Fundierung lebensrelevanter Bereiche philosophischer Praxis sind neben den methodischen Perspektiven der Praktischen Philosophie (Phänomenologie, Hermeneutik, Dialektik) vor allem anthropologische und allgemein ethische Fragestellungen. In Form einer integralen Philosophie und Ethik können diese philosophischen Kompetenzen dazu beitragen, sowohl in beratenden Berufen als auch in Berufen des Bildungssektors Hilfestellungen zu leisten. rnEin Anliegen der Philosophischen Praxis besteht dabei darin, das Selbstverständnis und Weltverständnis des Menschen in seiner Entwicklung zu fördern. Innerhalb dieses Bildungsprozesses der menschlichen Orientierungsfähigkeit in der Gesellschaft leisten gerade kulturanthropologische Untersuchungen zu kulturellen Phänomenen wertvolle Beiträge und sind daher für eine Deutung von Menschenbildern und kulturellen Ausprägungen fruchtbar zu machen. Das fachliche Selbstverständnis dieser Disziplin ist an der Schnittstelle verschiedener Geistes- und Sozialwissenschaften angesiedelt und liefert aufgrund seiner Alltags- und Lebensnähe eine wissenschaftliche Haltung im Sinne der Philosophischen Praxis, die sowohl den individuellen Menschen als auch seine wissenschaftliche Erforschung und Deutung im Blick hat.rnDies ist vor allem für fachdidaktische Überlegungen im Rahmen eines schulischen Philosophie- und Ethikunterrichts relevant, denen an sowohl fachwissenschaftlichen Diskursen als auch an Problemfragen der jeweils persönlich betroffenen Lerngruppe gelegen ist.rnDie Perspektiven der Philosophischen Praxis als Strömung der Praktischen Philosophie bestehen darin, für die Didaktik der Philosophie ein Instrumentarium in Form von Methoden, Problemfragen und Inhalten zusammenzustellen, das auch der Philosophie als Universitäts- und Unterrichtsfach neue Wege eröffnen kann.rnDaher soll die vorliegende Arbeit deutlich machen, dass die bisher in der akademischen Philosophie kaum oder wenig beachtete Form der Philosophischen Praxis als wichtiger Teil der Didaktik der Philosophie und Ethik erkannt werden kann. Die Philosophische Praxis in der hier zusammengestellten Form kann daher wichtige Impulse für eine sich entwickelnde Didaktik der Philosophie und Ethik liefern. rnDie Philosophie leistet dabei einen wichtigen Beitrag für einen integralen Bildungsbegriff. Die untersuchten Autoren und philosophischen Strömungen lassen erkennen, dass die Tradition der Philosophischen Praxis und Selbstsorge seit der Antike eine bedeutende Strömung der Philosophie darstellt, deren Wiederaufnahme von gesellschaftlicher Relevanz sein kann, da sie sich gerade zu Fragen der „Selbstfindung“, „Selbstverwirklichung“ und „Glückssuche“, wie sie in der Gegenwart virulent sind, philosophisch fundiert zu äußern vermag. Vor allem philosophiedidaktische Überlegungen sollten die an dieser Stelle bedeutsamen Konvergenzen akademischer Philosophie und alltäglicher Problemfragen, wie sie im schulischen Kontext zu stellen sind, berücksichtigen. Die im zweiten Teil der Arbeit durchgeführte kritische Untersuchung und Gegenüberstellung philosophiedidaktischer Positionen konnte zeigen, inwiefern verschiedene didaktische Konzepte Bezüge zu Themenfeldern der Philosophischen Praxis aufweisen. Dadurch konnte die Arbeit zeigen, inwiefern die zwei Bereiche der beratenden und schulischen Praxis der Philosophie im Zusammenhang stehen.rn

In this thesis we investigate the phenomenology of supersymmetric particles at hadron colliders beyond next-to-leading order (NLO) in perturbation theory. We discuss the foundations of Soft-Collinear Effective Theory (SCET) and, in particular, we explicitly construct the SCET Lagrangian for QCD. As an example, we discuss factorization and resummation for the Drell-Yan process in SCET. We use techniques from SCET to improve existing calculations of the production cross sections for slepton-pair production and top-squark-pair production at hadron colliders. As a first application, we implement soft-gluon resummation at next-to-next-to-next-to-leading logarithmic order (NNNLL) for slepton-pair production in the minimal supersymmetric extension of the Standard Model (MSSM). This approach resums large logarithmic corrections arising from the dynamical enhancement of the partonic threshold region caused by steeply falling parton luminosities. We evaluate the resummed invariant-mass distribution and total cross section for slepton-pair production at the Tevatron and LHC and we match these results, in the threshold region, onto NLO fixed-order calculations. As a second application we present the most precise predictions available for top-squark-pair production total cross sections at the LHC. These results are based on approximate NNLO formulas in fixed-order perturbation theory, which completely determine the coefficients multiplying the singular plus distributions. The analysis of the threshold region is carried out in pair invariant mass (PIM) kinematics and in single-particle inclusive (1PI) kinematics. We then match our results in the threshold region onto the exact fixed-order NLO results and perform a detailed numerical analysis of the total cross section.

In this thesis, we develop high precision tools for the simulation of slepton pair production processes at hadron colliders and apply them to phenomenological studies at the LHC. Our approach is based on the POWHEG method for the matching of next-to-leading order results in perturbation theory to parton showers. We calculate matrix elements for slepton pair production and for the production of a slepton pair in association with a jet perturbatively at next-to-leading order in supersymmetric quantum chromodynamics. Both processes are subsequently implemented in the POWHEG BOX, a publicly available software tool that contains general parts of the POWHEG matching scheme. We investigate phenomenological consequences of our calculations in several setups that respect experimental exclusion limits for supersymmetric particles and provide precise predictions for slepton signatures at the LHC. The inclusion of QCD emissions in the partonic matrix elements allows for an accurate description of hard jets. Interfacing our codes to the multi-purpose Monte-Carlo event generator PYTHIA, we simulate parton showers and slepton decays in fully exclusive events. Advanced kinematical variables and specific search strategies are examined as means for slepton discovery in experimentally challenging setups.

This paper reports on a Virtual Reality theater experiment named Il était Xn fois, conducted by artists and computer scientists working in cognitive science. It offered the opportunity for knowledge and ideas exchange between these groups, highlighting the benefits of collaboration of this kind. Section 1 explains the link between enaction in cognitive science and virtual reality, and specifically the need to develop an autonomous entity which enhances presence in an artificial world. Section 2 argues that enactive artificial intelligence is able to produce such autonomy. This was demonstrated by the theatrical experiment, "Il était Xn fois" (in English: Once upon Xn time), explained in section 3. Its first public performance was in 2009, by the company Dérézo. The last section offers the view that enaction can form a common ground between the artistic and computer science areas.

One fundamental question raised by the philosophical works of Maurice Blondel, which were published over a long life, is that of the relation between his early masterpiece L’Action (1893) and the volume of the same name—more precisely, its second tome L’Action humaine et les conditions de son aboutissement (1937)—forming part of the Trilogy of his later years (La Pensée; L’Être et les êtres; L’Action). The treatment of the nature of international relations in the work of 1937 is more developed than that found in L’Action of 1893. For understanding the development of Blondel’s thought on this matter, the key text is "Patrie et Humanité", a paper prepared for the 1928 annual meeting, held in Paris, of the Catholic Semaine sociale movement. It brings out the affinity between his understanding of international relations and that represented by such established thinkers in the canon of international thought as Vitoria and Suarez (in the case of the latter, despite some radical difference in respect of metaphysics). Not surprisingly from the standpoint of the genesis of Blondel’s philosophy, there is also a certain affinity between his view of the importance of justice for international affairs and that of Leibniz (notably in the preface of the Codex Juris Gentium, 1693). Various specialists treating of Blondel’s philosophy have drawn attention to parallels between the phenomenology of the will in L’Action of 1893 and Hegel’s Phänomenologie des Geistes. However, as regards the two philosophers’ understanding of the nature of international relations, there is a considerable gulf, and some of the difference may be related to the Hegelian idea of the Christian Church as found, at least implicitly, in the Grundlinien der Philosophie des Rechts (1821).
