Fasting shapes chromatin architecture through an mTOR/RNA Pol I axis.

Chromatin architecture is a fundamental mediator of genome function. Fasting is a major environmental cue across the animal kingdom, yet how it impacts three-dimensional (3D) genome organization is unknown. Here we show that fasting induces an intestine-specific, reversible and large-scale spatial reorganization of chromatin in Caenorhabditis elegans.

The non-use of evidence in the adoption of a sugar-sweetened beverage tax in OECD countries.

Background: Studies confirm the positive effect of sugar-sweetened beverage (SSB) taxation on public health. However, only a few countries in Europe adopt SSB taxes. From a public policy perspective, we investigate the conditions under which countries do or do not follow this evidence.

Public Policy Research-Born in the USA, at Home in the World?

Public policy emerged as an academic subfield in the United States after the second World War. The theoretical foundations of the discipline are essentially based on analyses of Anglo-Saxon policies and politics and were originally aimed at providing knowledge for the policy process of pluralistic democracies. Given the increasing transfer of the subject and related approaches to other countries, it is necessary to clarify how suitable theories, goals, and methods of policy research are applied in other contexts.

Social Identities in the Policy Process of Authoritarian Systems.

The integration of the social-psychological social identity approach to policy process research has recently generated new insights on policy-making. Empirical applications for established democracies and multilevel settings such as the European Union have identified five general types of social identities that are relevant for the preferences and behavior of policy actors and their stability and change over time. Social identities are based on joint memberships in social groups, such as organizations, demographic/biographical identities, sectors, locations, and informal opportunities for exchange (which may result in programmatic groups and identities).
