Ontic structural realism is the view that structures are what is real in the first place in the domain of fundamental physics. The structures are usually conceived as including a primitive modality. However, it has not been spelled out as yet what exactly that modality amounts to. This paper proposes to fill this lacuna by arguing that the fundamental physical structures possess a causal essence, being powers. Applying the debate about causal vs. categorical properties in analytic metaphysics to ontic structural realism, I show that the standard argument against categorical and for causal properties holds for structures as well. Structural realism, as a position in the metaphysics of science that is a form of scientific realism, is committed to causal structures. The metaphysics of causal structures is supported by physics, and it can provide for a complete and coherent view of the world that includes all domains of empirical science.

We first introduce structural realism as a position in the metaphysics of science, pointing out the way in which this position replaces intrinsic properties with relations so that it amounts to a holistic in contrast to an atomistic metaphysics. We argue in favour of a moderate version of structural realism that puts objects and relations on the same ontological footing and assess the general philosophical arguments for this position. The second section shows how structural realism gains support from quantum physics. The third section explains how structural realism can be applied to the metaphysics of space-time.

ABSTRACT This dissertation investigates the, nature of space-time as described by the theory of general relativity. It mainly argues that space-time can be naturally interpreted as a physical structure in the precise sense of a network of concrete space-time relations among concrete space-time points that do not possess any intrinsic properties and any intrinsic identity. Such an interpretation is fundamentally based on two related key features of general relativity, namely substantive general covariance and background independence, where substantive general covariance is understood as a gauge-theoretic invariance under active diffeomorphisms and background independence is understood in the sense that the metric (or gravitational) field is dynamical and that, strictly speaking, it cannot be uniquely split into a purely gravitational part and a fixed purely inertial part or background. More broadly, a precise notion of (physical) structure is developed within the framework of a moderate version of structural realism understood as a metaphysical claim about what there is in the world. So, the developement of this moderate structural realism pursues two main aims. The first is purely metaphysical, the aim being to develop a coherent metaphysics of structures and of objects (particular attention is paid to the questions of identity and individuality of these latter within this structural realist framework). The second is to argue that moderate structural realism provides a convincing interpretation of the world as described by fundamental physics and in particular of space-time as described by general relativity. This structuralist interpretation of space-time is discussed within the traditional substantivalist-relationalist debate, which is best understood within the broader framework of the question about the relationship between space-time on the one hand and matter on the other. In particular, it is claimed that space-time structuralism does not constitute a 'tertium quid' in the traditional debate. Some new light on the question of the nature of space-time may be shed from the fundamental foundational issue of space-time singularities. Their possible 'non-local' (or global) feature is discussed in some detail and it is argued that a broad structuralist conception of space-time may provide a physically meaningful understanding of space-time singularities, which is not plagued by the conceptual difficulties of the usual atomsitic framework. Indeed, part of these difficulties may come from the standard differential geometric description of space-time, which encodes to some extent this atomistic framework; it raises the question of the importance of the mathematical formalism for the interpretation of space-time.

Why do great powers expand? Offensive realist John Mearsheimer claims that states wage an eternal struggle for power, and that those strong enough to seek regional hegemony nearly always do. Mearsheimer's evidence, however, displays a selection bias. Examining four crises between 1814 and 1840, I show that the balance of power restrained Russia, Prussia and France. Yet all three also exercised self-restraint; Russia, in particular, passed up chances to bid for hegemony in 1815 and to topple Ottoman Turkey in 1829. Defensive realism gives a better account of the Concert of Europe, because it combines structural realism with non-realist theories of state preferences.

Liberal-Institutionalism and Structural Realism expectations about international organizations are confronted by looking at if and how US-controlled international aid is granted, and particularly if it is related or not to political affinity and to United Nations Security Council (UNSC) non-permanent membership. A preliminary assessment suggests that these relations only hold for the period of the Cold War, and, even then, only when UNSC non-permanent membership is in years in which the Security Council was deemed very important.

The paper spells out five different accounts of the relationship between objects and relations three of which are versions of ontic structural realism (OSR). We argue that the distinction between objects and properties, including relations, is merely a conceptual one by contrast to an ontological one: properties, including relations, are modes, that is the concrete, particular ways in which objects exist. We then set out moderate OSR as the view according to which irreducible relations are central ways in which the fundamental physical objects exist. Physical structures thus consist in objects for whom it is essential that they are related in certain ways. There hence are objects, but they do not possess an intrinsic identity. This view can also admit intrinsic properties as ways in which objects exist provided that these do not amount to identity conditions for the objects. Finally, we indicate how this view can take objective modality into account.

Este estudio de caso se enfoca en identificar cuales fueron los factores que motivaron la participación de los partidos kurdos PDK y UPK en la invasión a Irak 2003 – 2009. Con base en los supuestos teóricos de autores realistas K.Waltz, M. Ayoob y liberales y R. Keohane y J. Nye, se estudian las dinámicas y las interacciones que permitieron establecer un acercamiento con los Estados Unidos con un énfasis específico en los intereses políticos de los partidos kurdos. El kurdistán iraquí llega a ser el área clave para el acercamiento de la potencia a la zona y los intereses políticos permitieron establecer un escenario de cooperación e interdependencia, incrementando tanto la participación como la autonomía de los kurdos en las dinámicas del país y de la región.

El propósito principal de esta monografía es ofrecer una perspectiva crítica sobre el conflicto latente en la Península Coreana, haciendo un acercamiento al mismo desde un marco teórico asentado en el realismo estructural de Kenneth Waltz. De este modo, se busca responder a cuestiones sobre los intereses estatales como fundamento básico de las estrategias de mantenimiento de la Estructura en regiones geopolíticamente sensibles. Al final, se llega a la conclusión afirmando que la Estructura ejerce una serie de funciones para garantizar su preservación mediante una acción de convergencia en la conducta de los Estados. Esta realidad ha mantenido a la Península Coreana sin un conflicto bélico en los últimos 50 años, muy a pesar de estar al borde del mismo en varias ocasiones, ya que de llegarse a presentar se rompería la estabilidad de la región, y por ende el Equilibrio de Poderes estaría en grave riesgo.

El Grupo Visegrád es un escenario de cooperación multilateral, conformado por Polonia, República Checa, Eslovaquia y Hungría, el cual tiene como objetivo principal contribuir al cumplimiento de los intereses de dichos países, por medio de la financiación de proyectos culturales. El interés de esta monografía consiste en determinar la incidencia de la cooperación cultural en la reafirmación identitaria de cada uno de los miembros del Grupo y, por ende, en la manera como éstos se proyectan dentro de la Unión Europea. Así pues, se identifican los principales hechos históricos que han moldeado los intereses de los países del V4 y que condujeron a la creación de una estructura institucional sólida, que ha servido como plataforma para el accionar de dichos países dentro del bloque europeo. Se utiliza la perspectiva constructivista de Alexander Wendt, la cual permite entender la naturaleza de la cooperación y, su relación con las identidades y los intereses de los Estados.

El interés de esta monografía es evaluar la influencia del conflicto armado nepalí sobre las relaciones de Nepal con India y China. Se analiza y se explica como un conflicto armado interno puede influir desde sus causas, desarrollo y desenlace en las relaciones regionales y bilaterales de un país con sus vecinos. El presente texto pretende probar que la guerra civil de Nepal influyo positivamente en sus relaciones con India y China, planteando al país nepalí como un escenario en disputa entre estas dos potencias emergentes. Mediante el Realismo Estructural de Keneth Watlz se evaluaran las lógicas y los patrones de cambio que puedan modificar el sistema conformado por Nepal, China e India, para posteriormente examinar los cambios reales o parciales que sufrieron las relaciones de estos países al termino del conflicto armado.
