Assisted reproduction , particularly that performed using donated gametes, increases the prospect of healthy babies being delivered to increasing numbers of people striving for parenthood. The psychosocial, ethical and legislative issues related both to the donation and receipt of gametes are perceived as extraordinarily complicated. In 2009, a research project aimed at mapping the issues was drawn up and implemented in the Czech Republic. The project should have provided material for consultation purposes, for the work of ethical and legislative bodies, (...) and for better interdisciplinary and international communication in reproductive medicine. Work on the project was affected by several unforeseen events, particularly by the drafting and adoption of a new law on ART . The article describes the dynamic and structural changes occurring within the project due to drafting of the bill as well as the changes and consequences resulting from other circumstances related to the topic researched.

In the fearful ape hypothesis, Grossmann argues that heightened fearfulness increases human-unique cooperation. We suggest that this conclusion, however, may be premature. In particular, we question Grossmann's singling out of fear as the affective trait that enhances cooperative care. Additionally, we problematize the extent to which heightened fearfulness in humans, and its association with human-unique cooperation, are supported empirically.

A question dating to Mardešić and Prasolov’s 1988 work [S. Mardešić and A. V. Prasolov, Strong homology is not additive, Trans. Amer. Math. Soc. 307(2) (1988) 725–744], and motivating a considerable amount of set theoretic work in the years since, is that of whether it is consistent with the ZFC axioms for the higher derived limits [Formula: see text] [Formula: see text] of a certain inverse system [Formula: see text] indexed by [Formula: see text] to simultaneously vanish. An (...) equivalent formulation of this question is that of whether it is consistent for all [Formula: see text]-coherent families of functions indexed by [Formula: see text] to be trivial. In this paper, we prove that, in any forcing extension given by adjoining [Formula: see text]-many Cohen reals, [Formula: see text] vanishes for all [Formula: see text]. Our proof involves a detailed combinatorial analysis of the forcing extension and repeated applications of higher-dimensional [Formula: see text]-system lemmas. This work removes all large cardinal hypotheses from the main result of [J. Bergfalk and C. Lambie-Hanson, Simultaneously vanishing higher derived limits, Forum Math. Pi 9 (2021) e4] and substantially reduces the least value of the continuum known to be compatible with the simultaneous vanishing of [Formula: see text] for all [Formula: see text]. (shrink)
