Carne e bits : reflexões sobre a indiscernibilidade das fronteiras entre mentes e máquinas e os sistemas cognitivos híbridos

Faz reflexões sobre as várias formas de relação entre sujeitos e objetos-técnicos, com ênfase para a utilização dos computadores digitais e, particularmente, os softwares chamados agentes inteligentes. Analisa o espaço e suas mudanças qualitativas na atualidade, a partir do conceito do espaço como produção humana, analisando como as transformações em curso no ambiente afetam nossas subjetividades e, reciprocamente, como afetamos nossos ambientes. Discutidas as possibilidades de sobrevivência do homem nu nesses novos espaços, sem que esteja devidamente atualizado com as últimas novidades tecnológicas - próteses sensoriais e motoras. Perpassa a discussão sobre o pensamento que se utiliza do espaço como elemento constituinte do próprio pensamento e reflete sobre o espaço abstrato por excelência, os mundos virtuais. Discute o padrão de apropriação de artefatos pelo homem e seus efeitos na subjetividade, a manutenção do padrão de apropriação dos objetos-técnicos materiais em relação às formas de apropriação dos objetos-técnicos intangíveis (softwares). Traz reflexões sobre a possibilidade de autonomização completa dos agentes inteligentes e a sua instituição, ipso facto, como agentes - a chamada Inteligência Artificial.

Responding to desire to die statements from patients with advanced disease:recommendations for health professionals

It is not uncommon for patients with advanced incurable disease to express a desire to hasten their death. Health professionals often have difficulty responding to such statements, and find it challenging to ascertain why these statements are made. Health professionals may struggle to determine whether a 'desire to die' statement (DTDS) is about a request for hastened death, a sign of psychosocial distress, or merely a passing comment that is not intended to be heard literally as a death wish. Given the lack of guidelines to assist health professionals with this issue, we have prepared multidisciplinary recommendations for responding to a DTDS, underpinned by key principles of therapeutic communication and a systematic review of empirical literature. Where the relevant literature was lacking, the recommendations were drafted by the authors (clinicians and/ or academics from the following disciplines: nursing, medicine, psychiatry, psychology, sociology, aged care and theology), based on their expert opinion. Multiple drafts of the recommendations were circulated to the authors for refinement until consensus was reached. Strategies for advancing the evidence base for the maturation of guidelines in this area are offered.

Um contraste entre as teorias cognitivas da consciência de Baars e Dennett: o espaço de trabalho global seria um teatro cartesiano?

Is global workspace a cartesian theater? How the neuro-astroglial interaction model solves conceptual issues

The Global Workspace Theory (GWT) proposed by Bernard Baars (1988) along with Daniel Dennett’s (1991) Multiple Drafts Model (MDM) of consciousness are renowned cognitive theories of consciousness bearing similarities and differences. Although Dennett displays sympathy for GWT, his own MDM does not seem to be fully compatible with it. This work discusses this compatibility, by asking if GWT suffers from Daniel Dennett’s criticism of what he calls a “Cartesian Theater”. We identified in Dennett 10 requirements for avoiding the Cartesian Theater. We believe that some of these requirements are violated by GWT, but not all, hence there is partial incompatibility with MDM, and it is nonsense to answer if GWT is or is not a Cartesian Theater. However, by asking such question we conclude that the issues around this discussion involve fuzzy claims about degrees of consciousness and we show how the Neuro-Astroglial Interaction Model (NAIM) is fit for solving such conceptual issues.
