This is a book about speech and the silencing of speech; about who gets to speak and who does not; about who is listened to and who is ignored. In this down-to-earth analysis of the democratic principle of freedom of speech, Betty McLellan insists that, if this prized democratic principle is to have any continuing credibility, free speech must be free for all.

The objective of this study—a substudy to a phase I bioequivalence study—was to compare the effect of standard and concise consent forms on research volunteers’ comprehension of and satisfaction with consent forms, as well as to assess the effect of select volunteer characteristics, such as financial motivations to participate in research, on their comprehension. A 36-item questionnaire measured volunteers’ comprehension, satisfaction, and motivations for participation. Volunteers were randomized to the standard Pfizer consent form or a concise, easier-to-read form. We approached (...) 139 volunteers to participate, and 138 completed the questionnaire . The cohorts did not differ in sociodemographic characteristics. We found that the average comprehension scores for the standard consent form cohort and the concise consent cohort were about the same, and that satisfaction with the consent form was high in both cohorts. Surprisingly, volunteers with a financial motivation had significantly greater comprehension of the study. (shrink)

Stem cell tourism is a small but growing part of the thriving global medical tourism marketplace. Much stem cell research remains at the experimental stage, with clinical trials still uncommon. However, there are over 700 clinics estimated to be operating in mostly developing countries – from Costa Rica and Argentina to China, India and Russia – that have lured many patients, mostly from industrialized countries, driven by desperation and hope, which in turn continue to fuel the growth of such tourism.While (...) much research has focused on such dimensions as the promotions that allow such businesses to make their services known, media coverage, some patient research, and regulatory conditions for developing country clinics, little attention has been paid to the non-affected members of the general population, the future potential users of such services. This empirical study based on five focus group discussions with a diverse group of healthy adults in a Canadian city, explored participant views of patients who use stem cell tourism services, the likelihood they would avail themselves of such services if they were to suffer similar illnesses, and the conditions under which they might do so, and the impact that admonitions and advice from international expert bodies might have on their decisions. Our findings suggest that these healthy adults are sympathetic to the drivers of hope and desperation, and, despite cautions about research limitations, may seek such treatments themselves under similar conditions. These findings are discussed in the context of the policy and ethical issues raised by this form of medical tourism. (shrink)

Resumo: Neste artigo, argumentamos a favor de uma versão sofisticada do realismo científico, tendo como eixo norteador a análise do desempenho do que consideramos ser o seu elemento de defesa estratégico: o “argumento do milagre”. O realismo científico é a perspectiva comprometida com as nossas melhores teorias científicas, isto é, com a existência de entidades, processos, relações etc., observáveis ou inobserváveis, indispensáveis para explicar o seu sucesso empírico, em particular, com aqueles componentes das teorias que são cruciais para se alcançar (...) novas previsões bem-sucedidas. O argumento do milagre é um tipo de abdução ou inferência da melhor explicação e se expressa na célebre formulação de Putnam : “O realismo científico é a única filosofia que não faz do sucesso da ciência um milagre.” Analisamos e rebatemos duas importantes modalidades de argumentação antirrealista: a indução pessimista e a circularidade viciosa da inferência da melhor explicação. Acreditamos estar justificados quanto à defesa da intuição básica do realismo científico, com o apoio de uma versão fortalecida e articulada do argumento do milagre, mediante as qualificações de novidade preditiva e fecundidade teórica: a ciência é bem-sucedida em explicar e prever fenômenos, inclusive novos, porque suas melhores teorias são verdadeiras e as entidades inobserváveis postuladas por essas teorias realmente existem. Concluímos que o argumento do milagre continua sendo basilar e estratégico na defesa do realismo científico.: In this article, we argue in favor of a sophisticated version of scientific realism, based on an analysis of what we consider to be the strategic element of its defense: the “miracle argument”. Scientific realism is the perspective applicable to our best scientific theories; that is, it applies to entities, processes, and relationships, etc., whether observable or unobservable, which are indispensable for explaining the empirical success of theories, and it applies particularly to those components of the theories that are crucial to achieving new and successful forecasts. The miracle argument is a type of abduction or inference to the best explanation, and is expressed in the famous formulation of Putnam : “[Scientific] realism is the only philosophy that doesn’t make the success of the science a miracle.” We analyze and refute two important modes of antirealist argument: pessimistic induction and vicious circularity of inference to the best explanation. We believe that we are justified in defending the basic intuition of scientific realism, supported by a strengthened version of the miracle argument, together with the attributes of predictive novelty and theoretical fecundity. From this perspective, science succeeds in explaining and predicting phenomena, including new phenomena, because its best theories are true, and the unobservable entities postulated by these theories actually exist. We conclude that the miracle argument continues to be basic and strategic in the defense of scientific realism. (shrink)

The paper tries to show that an evolutionary perspective helps us to address what is called the adaptation problem, that is, the remarkable coherence, and seemingly successful design, existing between our cognitive tools and the phenomena of the material world. It argues that a fine-grained description of the structure and function of experimental techniques—as a special type amongst evolving scientific practices—is a condition for a better understanding and, ultimately, an explanation of how adaptation among the heterogeneous elements of experimental knowledge (...) is attained. Some apparently contradictory features of techniques, such as their high context-dependency and their capabilities to reproduce and diversify outside their original contexts, are addressed with the help of the concepts of technical variation and the historical entrenchment of phenomena in techniques. In order to do so, a case-study on the construction of satellite-DNA and the evolution of nucleic acid hybridization, a research project carried out by Roy J. Britten and his colleagues in the 1960s, is presented in detail. This case illustrates the close relationship existing between the evolution of techniques and the stabilization of phenomena in experimental biology. (shrink)

Xenotransplantation, or the use of animal cells, tissues and organs for humans, has been promoted as an important solution to the worldwide shortage of organs. While scientific studies continue to be done to address problems of rejection and the possibility of animal-to-human virus transfer, socio-ethical and legal questions have also been raised around informed consent, life-long monitoring, animal welfare and animal rights, and appropriate regulatory practices. Many calls have also been made to consult publics before policy decisions are made. This (...) paper describes the Canadian public consultation process on xenotransplantation carried out by the Canadian Public Health Association in an arm’s length process from Health Canada, the ministry overseeing government health policy and regulation. Focusing on six citizen fora conducted around the country patterned after the citizen jury deliberative approach, the paper describes the citizen panelists’ recommendations to hold off on proceeding with clinical trials and the rationales behind this recommendation. The consultation process is discussed in the context of constructive technology assessment, a framework which argues for broader input into earlier stages of technology innovation, particularly at the technology design stage.

O presente artigo analisa o projeto filosófico de John Dewey (1859-1952) que consta de uma crítica radical à epistemologia tradicional a partir da concepção pragmatista de experiência. O status científico da filosofia, conforme Dewey, não exigirá uma teoria científica passível de prova, mas um programa metafísico construído a partir de lógicas situacionais. O presente artigo apresenta as dimensões históricas e científicas da metafísica empírica de Dewey, argumentando a favor da articulação entre as duas abordagens que configuram o projeto de reconstrução (...) da filosofia. Dewey compreende que a busca dos fundamentos últimos tornou a filosofia prisioneira de uma imagem da mente como construtora de representações - algumas exatas, outras não, mas todas com a pretensão de serem estudadas por meio de métodos puros, não empíricos. Diferentemente dessa tradição que supõe uma ideia de superioridade intelectual do saber, revelado por meio de métodos não empíricos, Dewey argumenta a favor do empírico em filosofia e se coloca contra uma comum concepção da realidade como segura, regular e acabada. Palavras Chave: Experiência. Natureza. Metafísica empírica. Reconstrução filosófica. (shrink)

Lotman’s contribution to semiotic theory, anthroposemiotics, the study of artistic texts and defining the relationship between language and culture represent some of the most powerful work produced within the Tartu–Moscow School of Semiotics. The importance of translation is one of the central principles that unites all of Lotman’s work. In the following paper, we will consider Lotman’s definition of translatability in the context of (1) the definition of semiospheric internal and external boundaries and the importance of crossing these boundaries, (2) (...) the role of no fewer than two languages as a minimal unit of semiotic meaning-generation, (3) culture text-level generation of collective memory, and (4) the ever-present tension in the communication act. In our concluding section, we will offer an extended model of the communication act, based on the fundamental principles given in Jakobson, Sebeok and Lotman, in order to specify important moments of the translation process.

A collection of essays by nine prominent thinkers on the compatibility of socialism and democracy and its future.

Dewey desenvolveu um programa doutrinário que visa mostrar como o conhecimento se funda na experiência. Essa é a dimensão científico-naturalista da sua obra. Nesse sentido, o seu projeto consiste numa rigorosa argumentação contra as explicações em que a experiência e a natureza são apresentadas com base em distinções arbitrárias. Na obra, Reconstruction in Philosophy [Reconstrução em Filosofia], Dewey desenvolveu seu projeto metafísico de dimensão historicista, propondo uma reconstrução para a filosofia. Em Experience and Nature [Experiência e Natureza], ele apresentou uma (...) visada científica para a metafísica. Nessa obra, Dewey tenta pensar um sistema desenvolvido a partir da aplicação do método científico à filosofia tendo como base uma concepção filosófica da experiência. As concepções de Dewey acerca do conhecimento, do uso inteligente da razão e da natureza social da filosofia concorrem para a constituição de sua concepção de ciência. Nas duas obras fica evidente a sua crítica à noção tradicional de conhecimento como representação da realidade. Contra isso, Dewey passa a designar o conhecimento como um conjunto de “crenças” e “proposições” tomadas como garantias de usos ou assertividade garantida. Dewey se opõe à forma pela qual o problema epistemológico é formulado pela tradição, ou seja, a partir de uma posição realista ingênua no qual o conhecimento é visto como representação, desconsiderando o processo de conexão entre as coisas e entre o conhecedor e as coisas.
