One of the underlying ethical values of the Patient Self-Determination Act (PSDA) is the legal right of patients to decide on their own medical care, i.e., to accept or refuse medical treatment. Yet, there is a growing concern that a patient's legal right to determine medical treatment might result in health care professionals violating their own personal and/or professional ethical values. I shall therefore briefly review the requirements of the PSDA and outline the consequences of this act for a particular (...) case. The application of the Act becomes problematic in this case because the health care professionals involved believe that the treatments involved are medically futile. I consider the potential conflict between autonomy and futility. The thesis defended is that patient autonomy is not an absolute moral right and that health care professionals are not only permitted, but are sometimes morally required, to withhold and/or withdraw futile treatments even if the patient or the patient's surrogate request (demand!) that the treatments be continued.

Darwin proposed that evolutionary novelties are environmentally induced in organisms “constitutionally” sensitive to environmental change, with selection effective owing to the inheritance of constitutional responses. A molecular theory of inheritance, pangenesis , explained the cross‐generational transmission of environmentally induced traits, as required for evolution by natural selection. The twentieth‐century evolutionary synthesis featured mutation as the source of novelty, neglecting the role of environmental induction. But current knowledge of environmentally sensitive gene expression, combined with the idea of genetic accommodation of mutationally (...) and environmentally induced change, supports a revival of Darwin's original theory that is consistent with modern molecular and population genetics. †To contact the author, please write to: Smithsonian Tropical Research Institute, c/o Escuela de Biología, Universidad de Costa Rica, Costa Rica; e‐mail: [email protected].

Die AutorInnen aus der Humangeographie und Soziologie leisten einen Beitrag zur raumbezogenen qualitativen Sozialforschung, indem sie in kritischer Reflexion auf den spatial turn die soziale Welt erforschen und interpretieren. Einer schlagwortartig vorgebrachten Renaissance des Raumes in den Sozial- und Kulturwissenschaften werden konkrete qualitativ-empirische und theoretisch-konzeptionelle Arbeiten gegenübergestellt, die einen eigenständigen, raumreflektierten Zugang zur Thematik bieten. Die AutorInnen verfolgen zwei Ziele: Zum einen geht es um die Überwindung von „just-do-it“-Ansätzen in der (raumbezogenen) Methodologie. Zum anderen wird deutlich, dass eine eingehende methodologische (...) Reflexion kein redundanter Aspekt ist oder einen lässlichen Arbeitsschritt darstellt, sondern entscheidender Bestandteil qualitativer Forschungslogik sein muss. Gefordert ist hierfür eine Debatte sowohl über die theoretischen Grundlagen einer solchen Positionierung, als auch die Diskussion ihrer praktischen Umsetzungen in der empirischen Forschung. Die AutorInnen demonstrieren, dass mit ‚Raum‘ qualitativ verfahren werden kann und die Sensibilität hinsichtlich relationaler und praxeologischer Raumbezüge in der qualitativen Sozialforschung gestärkt werden kann.
