    At very high energies, the high parton densities (characterized by a semi-hard saturation scale \Lambda_s) ensure that parton distributions can be described by a classical effective field theory with remarkable properties analogous to those of spin glass systems. This color glass condensate (CGC) of gluons also provides the initial conditions for multi-particle production in high energy nuclear collisions. In this talk, we briefly summarize recent theoretical and phenomenological progress in the CGC approach to small x physics. In particular, we discuss recent numerical work on the real time gluodynamics of partons after a nuclear collision. The implications of this work for the theoretical study of thermalization in nuclear collisions and on the phenomenological interpretation of results of the recent RHIC experiments are also discussed.Comment: LaTex, 8 pages.

    Research on humanistic-experiential psychotherapies

    In this chapter we focus on research published since our previous reviews (Greenberg, Elliott & Lietaer, 1994; Elliott, Greenberg & Lietaer, 2004), which covered research published between 1978 and 2001, plus additional earlier research on humanistic-experiential psychotherapy (HEP) outcome that we have been able to track down. A key element of the chapter is a meta-analysis of nearly 200 HEP outcome studies (through 2008) and a survey of the use of the approach with different client groups. In addition, we offer a meta-synthesis of qualitative research on these therapies (cf. Timulak, 2007), and provide a narrative review of recent quantitative research on change processes in HEPs. We conclude by reviewing and integrating the literature reviewed and discuss policy implications

    Da pågina ao(s) ecrã(s): tecnologia, educação e cidadania digital no século XXI

    Na atual sociedade em rede, a relação entre literacia e tecnologia tem vindo a estreitar-se, abrindo um amplo debate sobre as vantagens da utilização das TIC em contexto escolar, para acompanhar o ritmo das geraçÔes quotidianamente rodeadas de ecrĂŁs que as convidam a explorar novas formas de “ler” o mundo. Partindo deste pressuposto, os objetivos do artigo sĂŁo: 1) fazer uma revisĂŁo de literatura sobre a evolução conceptual da literacia digital, sublinhando a pluralidade das suas facetas e a sua relevĂąncia em contexto escolar; 2) refletir sobre o modo como tal evolução alimenta e consolida o exercĂ­cio da cidadania digital, tendo como objetivo a promoção da e-inclusĂŁo; 3) indagar o modo como a escola tem sido desafiada a integrar as TIC em contexto de sala de aula, a partir de uma seleção de estudos que, por um lado, configuram um retrato possĂ­vel da atual “geração digital” e, por outro lado, incidem sobretudo em exemplos concretos de atividades realizadas no ensino bĂĄsico, enfatizando as perceçÔes e atitudes de professores e alunos nelas envolvidos. Finalmente, conclui-se que os avanços conseguidos sĂŁo um incentivo para repensar a implementação sistemĂĄtica de processos de utilização pedagĂłgica das TIC no ensino e aprendizagem enquanto um dos pilares do futuro digital da educação
