Futuros designers como agentes de mudança : exploração do ensino do design focado em inovação social e sustentabilidade

ABSTRACT : This paper, part of a Ph.D. in Design research, focused on discussing the role of Design Education on training future designers to be actors of change. It describes the methodology of a workshop for design students during the Design Week of Mérida, at Universidad de Extremadura – Spain. The workshop discussed the point of view of students in problem-solving, and what they believe to be the skills, methods, and partnerships for design to achieve such a change in its approach and how Design Education plays a part in preparing the future genera_on of designers to tackle social innovation and sustainability problems. The results showed how these particular group of future designers see as crucial in the given context and the possibilities for improvement on a system that struggles to be resilient and respond at a faster pace.O presente trabalho é parte do projeto de investigação para o programa de Doutoramento em Design e foca em discutir o papel do Ensino do Design na educação de futuros designers como agentes de mudança. O artigo descreve a metodologia aplicada a um workshop facilitado para alunos de design durante a Semana de Design de Mérida, na Universidad de Extremadura, em Espanha. A atividade discutiu os pontos de vista dos estudantes no tocante à resolução de problemas complexos e suas crenças sobre as habilidades, métodos e parcerias necessárias ao Design para que alcance as mudanças necessárias, para além de discutir o papel do Ensino do Design na preparação da futura geração de profissionais focados na resolução de problemas de sustentabilidade e inovação social. O resultado demonstra o que este particular grupo de futuros designers entendem como sendo crucial neste contexto e as possibilidades para melhorias em um sistema que sofre para se tornar resiliente e responder às questões sociais de maneira mais ágil.info:eu-repo/semantics/publishedVersio

Ground state for a massive scalar field in BTZ spacetime with Robin boundary conditions

We consider a real, massive scalar field in BTZ spacetime, a 2+1-dimensional black hole solution of the Einstein's field equations with a negative cosmological constant. First, we analyze the space of classical solutions in a mode decomposition and we characterize the collection of all admissible boundary conditions of Robin type which can be imposed at infinity. Secondly, we investigate whether, for a given boundary condition, there exists a ground state by constructing explicitly its two-point function. We demonstrate that for a subclass of the boundary conditions it is possible to construct a ground state that locally satisfies the Hadamard property. In all other cases, we show that bound state mode solutions exist and, therefore, such construction is not possible.Comment: 17 pages, 3 figure

Mode solutions for a Klein-Gordon field in anti-de Sitter spacetime with dynamical boundary conditions of Wentzell type

We study a real, massive Klein-Gordon field in the Poincar\'e fundamental domain of the $(d+1)$-dimensional anti-de Sitter (AdS) spacetime, subject to a particular choice of dynamical boundary conditions of generalized Wentzell type, whereby the boundary data solves a non-homogeneous, boundary Klein-Gordon equation, with the source term fixed by the normal derivative of the scalar field at the boundary. This naturally defines a field in the conformal boundary of the Poincar\'e fundamental domain of AdS. We completely solve the equations for the bulk and boundary fields and investigate the existence of bound state solutions, motivated by the analogous problem with Robin boundary conditions, which are recovered as a limiting case. Finally, we argue that both Robin and generalized Wentzell boundary conditions are distinguished in the sense that they are invariant under the action of the isometry group of the AdS conformal boundary, a condition which ensures in addition that the total flux of energy across the boundary vanishes.Comment: 12 pages, 1 figure.
