Since it was first published, Quantum Field Theory in a Nutshell has quickly established itself as the most accessible and comprehensive introduction to this profound and deeply fascinating area of theoretical physics. Now in this fully revised and expanded edition, A. Zee covers the latest advances while providing a solid conceptual foundation for students to build on, making this the most up-to-date and modern textbook on quantum field theory available. -/- This expanded edition features several additional chapters, as well as (...) an entirely new section describing recent developments in quantum field theory such as gravitational waves, the helicity spinor formalism, on-shell gluon scattering, recursion relations for amplitudes with complex momenta, and the hidden connection between Yang-Mills theory and Einstein gravity. Zee also provides added exercises, explanations, and examples, as well as detailed appendices, solutions to selected exercises, and suggestions for further reading. (shrink)

Concept of ethics in Ādi-Granth, Sikh canon.

Estudio sistemático sobre la imagen y sus complejas relaciones con el lenguaje verbal, partiendo de una crítica al logocentrismo en su vertiente racionalista -que reduce el conocimiento y el pensamiento al discurso lingüístico- para desembocar en una teoría de la representación. El autor sostiene que la imagen va más allá de la representación al tornarse presencia, basándose en el examen de pensadores clásicos y teóricos actuales que han abordado cuestiones afines. Propone una teoría de la imagen que no se ciñe (...) sólo a lo visual, sino que reconoce las dimensiones no visuales de lo imaginal: "el principal objetivo de este libro es contribuir a la construcción de una filosofía de la imagen. Hoy en día es ya una necesidad urgente contar con un aparato conceptual que nos permita afrontar las distintas modalidades de lo imaginal, que aparecen en ámbitos tan diversos como la intimidad psicológica, la ciencia, la filosofía, la comunicación masiva, la religión, la educación, la propaganda o el arte".

In this paper we examine the functional anatomy of volition, as revealed by modern brain imaging techniques, in conjunction with neuropsychological data derived from human and non-human primates using other methodologies. A number of brain regions contribute to the performance of consciously chosen, or ‘willed', actions. Of particular importance is dorsolateral prefrontal cortex , together with those brain regions with which it is connected, via cortico-subcortical and cortico-cortical circuits. That aspect of free will which is concerned with the voluntary selection (...) of one action rather than another critically depends upon the normal functioning of DLPFC and associated brain regions. Disease, or dysfunction, of these circuits may be associated with a variety of disorders of volition: Parkinson's disease, ‘utilization’ behaviour, ‘alien’ and ‘phantom’ limbs, and delusions of ‘alien control’ . Brain imaging has allowed us to gain some access to the pathophysiology of these conditions in living patients. At a philosophical level, the distinction between ‘intentions to act', and ‘intentions in action’ may prove particularly helpful when addressing these complex disturbances of human cognition and conscious experience. The exercise and experience of free will depends upon neural mechanisms located in prefrontal cortex and associated brain systems. (shrink)

HSÜN Tzu's essay on "Rectifying Terms" is justly considered a work of "great logical interest." For in this essay, one finds a remarkably modern concern with such topics as the rationale for having terms; the empirical and pragmatic bases for the classification of terms; the formation of generic and specific terms; the importance of observing established linguistic practices; the necessity of complying with proper standards for the institution, ratification, and regulation of the uses of language ; the nature of argumentative (...) discourse ; and the problems inherent in successful linguistic communication. A careful examination of some passages in other essays also suggests an awareness of the distinction between deductive, inductive, and analogical inferences, though Hsün Tzu provides us no explicit discussion of the nature of reasoning and its validating rules.

International Relations and the Philosophy of History examines the concept of civilization in relation to international systems through an extensive use of the literature in the philosophy of history. A. Nuri Yurdusev demonstrates the relevance of a civilizational approach to the study of contemporary international relations by looking at the multi-civilizational nature of the modern international system, the competing claims of national and civilizational identities and the rise of civilizational consciousness after the Cold War.

Anistia e as Ambivalências do Cinismo- A ADPF 153 e Micropolíticas da Memória consiste em uma primeira aproximação da pesquisa dos problemas contemporâneos suscitados por um tema cujo aparente anacronismo revela progressivamente sua extemporânea atualidade- o da anistia no Brasil, suas consequências éticas e políticas na transição do Estado brasileiro, e de suas instituições à democracia. Estes estudos foram escritos na atmosfera do debate público suscitado por ocasião do julgamento da ADPF 153 - sob todos os aspectos - sua propositura, (...) pelo Conselho Federal da OAB, consistiu em um gesto simbólico com o potencial de reabrir internamente o debate jurídico, ético e político sobre os temas da anistia e da responsabilização de agentes de Estado, civis e militares, violadores de direitos humanos no Brasil. Decantados nos anos seguintes, os textos que apresentamos ao leitor foram revistos e ampliados à luz de alguns encontros e oportunidades para debater o tema em espaços de pesquisa e de divulgação acadêmica privilegiados.
