Biobank research is potentially fruitful. It is argued that broad consent is acceptable for future research on biological material because a) the benefit is high, b) it pays respect to people’s autonomy, c) it is consistent with current practices and d) because the risk is low. Furthermore, broad consent should be allowed if information is handled safely, people can withdraw and expanded research should be approved by an ethics review board. However, these arguments are flawed and the criteria (...) for broad consent are either too restrictive to allow any research or fail to address important challenges with biobank research. Broad consent for biobank research can hide substantial ethical challenges and threaten trust in research. This does not mean that biobank research should be abandoned or that people cannot authorise future research on donated biological material. (shrink)

« La fin du SIDA » prévue en 2030 par le plan 90-90-90 de l’ONUSIDA est-elle possible au Québec? L’offre universelle proportionnée et systématique de dépistage avec consentement opt-out (consentement présumé) apparait comme la politique sanitaire la plus pertinente et équitable à mettre en place en vue d’identifier les personnes vivant avec le VIH ignorant leur statut sérologique. Cette démarche à première vue contraignante vis-à-vis des libertés individuelles peut être largement compensée par des bénéfices sanitaires, sociaux, économiques et structurels à (...) l’échelle individuelle et populationnelle. Dans la mesure où le VIH/SIDA reste un révélateur puissant des inégalités sociales, cette approche ne sera prolifique qu’en présence d’une ambition politique d’amélioration de l’accès aux soins et de couverture sanitaire universelle et inclusive à l’égard des individus échappant au dépistage. L’approche opt-out au sein des groupes à forte prévalence est une stratégie éthiquement pertinente pour augmenter les taux de dépistage. Bien que le consentement n’y soit pas explicite, la présomption tiendrait compte de « l’injustice structurelle » auxquels les groupes clés – présentant de forts taux de prévalence – sont soumis initialement. Cette dernière est responsable de leurs difficultés d’accès aux soins et aux dépistages. Cet article propose d’uniformiser l’offre de dépistage. Le Comité des Infections Transmissibles Sexuellement et par le Sang du Québec recommande actuellement l’approche opt-in pour les groupes-clés et le consentement opt-out en population générale. Nous pensons que cette différenciation constitue une barrière dans l’accès au dépistage et produit un effet d’éviction des groupes-clés craignant la stigmatisation. (shrink)

In her interesting paper on cross-jurisdictional legal approaches to brain death, Ariane Lewis considers whether informed consent is required for DNC testing in the UK, and proposes that it is not...

In [5] we study Nonassociative Lambek Calculus augmented with De Morgan negation, satisfying the double negation and contraposition laws. This logic, introduced by de Grooté and Lamarche [10], is called Classical Non-Associative Lambek Calculus. Here we study a weaker logic InNL, i.e. NL with two involutive negations. We present a one-sided sequent system for InNL, admitting cut elimination. We also prove that InNL is PTIME.

In his article “Nudging and Informed Consent,” Shlomo Cohen (2013) argues, among other things, that 1) “to the extent that the nudge-influenced decision making is rational—in whatever sense,” there...

The λY calculus is the simply typed λ calculus augmented with the fixed point operators. We show three results about λY: the word problem is undecidable, weak normalisability is decidable, and higher type fixed point operators are not definable from fixed point operators at smaller types.

When individual patients' medical decisions contribute to population-level trends, physicians may struggle with how to promote justice while maintaining respect for patient autonomy. This article argues that this tension might be resolved by using the informed consent conversation as an opportunity to position patients as societal stewards.

Electronic informed consent represents an opportunity to redesign the way that participants understand and elect to enroll in clinical research studies. However, electronic consent faces certain barriers common to all informed consent processes and other barriers specific to the technical environment. At Sage Bionetworks, we designed an electronic consent process as a software product and released it as an open source tool. We believe that using contemporary design processes to intentionally create cognitive friction, where potential study (...) participants are confronted with interfaces that require them to slow down and contemplate study concepts, offers a significant opportunity for ethical design as research increasingly uses smartphones and digital methodologies.

Informed consent is a perennial topic in bioethics. It has given the field a place in clinical practice and the law and is often the starting point for introductory instruction in medical ethics. One would think that nearly everything has been said and done on this well-worn topic.

Furthermore, adults with decision-making capacity, including pregnant women, can currently accept interventions with moderate net risks for themselves in other settings (e.g., open f...

The derivative is a basic concept of differential calculus. However, if we calculate the derivative as change in distance over change in time, the result at any instant is 0/0, which seems meaningless. Hence, Newton and Leibniz used the limit to determine the derivative. Their method is valid in practice, but it is not easy to intuitively accept. Thus, this article describes the novel method of differential calculus based on the double contradiction, which is easier to accept intuitively. (...) Next, the geometrical meaning of the double contradiction is considered as follows. A tangent at a point on a convex curve is iterated. Then, the slope of the tangent at the point is sandwiched by two kinds of lines. The first kind of line crosses the curve at the original point and a point to the right of it. The second kind of line crosses the curve at the original point and a point to the left of it. Then, the double contradiction can be applied, and the slope of the tangent is determined as a single value. Finally, the meaning of this method for the foundation of mathematics is considered. We reflect on Dehaene’s notion that the foundation of mathematics is based on the intuitions, which evolve independently. Hence, there may be gaps between intuitions. In fact, the Ancient Greeks identified inconsistency between arithmetic and geometry. However, Eudoxus developed the theory of proportion, which is equivalent to the Dedekind Cut. This allows the iteration of an irrational number by rational numbers as precisely as desired. Simultaneously, we can define the irrational number by the double contradiction, although its existence is not guaranteed. Further, an area of a curved figure is iterated and defined by rectilinear figures using the double contradiction. (shrink)
