The Structure of Idealization in Biological Theories: The Case of the Wright-Fisher Model

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual and hypothetical conditionals that can exhibit different ??degrees of contingency??. We use this idea to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, this structure explains why idealizations, despite being deformations of reality, are so successful in scientific practice. For illustrative purposes, we provide an example from population genetics, the Wright-Fisher Model.     

The Influence of Sex Information on Gender Word Processing

Three different tasks (word repetition, lexical decision, and gender decision) were designed to explore the impact of the sex clues (sex of the speaker, sex of the addressee) and the type of gender (semantic, arbitrary) on the processing of isolated Spanish gendered words. The findings showed that the grammatical gender feature was accessed when no mandatory attentional focus was required. In addition, the results indicated that the participants organize information according to their own sex role, which provides more salience to the words that match in grammatical gender with their own sex role representation, even when the gender assignment is arbitrary. Finally, the sex of the speaker biased the lexical access and the grammatical gender selection, serving as a semantic prime when the two dimensions have a congruent relationship. Furthermore, the masculine form serves as the generic gender representing both male and female figures.     

BRIEF REPORT Set‐shifting and sensitivity to reward: A possible dopamine mechanism for explaining disinhibitory disorders

The objective of this study was to investigate personality correlates of set‐shifting behaviour using a task sensitive to dopaminergic activity. As expected, set‐shifting behaviour was positively correlated with scores on the Sensitivity to Reward scale, a measure of Gray's impulsivity. Discussion is focused on the relationship between this greater ability for set‐shifting and the proneness to disinhibition.     

Doctors with borders? An authority-based approach to the brain drain1

According to the brain drain argument, there are good reasons for states to limit the exit of their skilled workers (more specifically, healthcare workers), because of the negative impacts this type of migration has for other members of the community from which they migrate. Some theorists criticise this argument as illiberal, while others support it and ground a duty to stay of the skilled workers on rather vague concepts like patriotic virtue, or the legitimate expectations of their state and co-citizens. In this article, on the contrary, we suggest that the liberal conception of states’ legitimate political authority demands, and not just permits, that developing states from which migration of skilled workers occurs set up contractual mechanisms. These mechanisms will ensure that state-funded training in the health sector is provided against a commitment on the part of future professionals to reciprocate with their services for the benefits obtained. If one of the conditions for the state to maintain legitimate political authority is to provide basic services such as healthcare to its subjects (while respecting at the same time their autonomy and freedom), then this is what developing states affected by the brain drain ought to do. What we call the authority-based approach to the brain drain also helps to clarify the obligations that other states have not to interfere with these contractual mechanisms when they exist, and not to profit from their absence. Inspired by FIFA’s legal instruments of training compensation and solidarity mechanism for the transfer of players, we conclude by suggesting a plausible global policy to complement this authority-based approach.
