AbstractFor many years research on development has been focused on complex economic models. However, the underdevelopment phenomenon entails important cultural aspects which have been barely explored. One of those aspects is the relationship between legal culture and the rule of law, and its effects on development. The aim of this article is to find evidence of the relationship between the lack of the binomial rule of law/legal culture and underdevelopment. The article states that legal culture and rule of law, as factors for development, are a binomial, meaning that, in the research of development/underdevelopment phenomenon, those factors are to be studied together. Rule of law, in terms of its relationship with development, should not be conceived as a mere formal expression of generalized submission to laws, including on the part of the organs of the State itself, but it should also be observed from a broader perspective. Hence its necessary connection with the legal culture, as the existence of these laws and the actual fact that people, generally, be conscious of them and their conduct be guided by them. The existence of the binomial rule of law/legal culture constitutes, in this way, a framework for the flourishing of development in a given region or country.

This article discusses the use of economic models for understanding law. It begins by describing the nature of economic models in general, and then turns to the specific application of economic models to law. It distinguishes between ‘economic analysis of law’, which concerns the use of economic theory for describing the incentive effects of legal rules (positive analysis) and for prescribing better rules (normative analysis); and ‘law and economics’, which concerns the relationship between law and markets as alternative institutions for organizing economic activity. The article concludes with some comments on the actual process of building economic models of law.

Aim: This article was written out of a felt need to reflect on the relationship between economic theories and models on the one hand and the empirical world as we experience it on the other. The question is in particular whether it is possible for economic models and theories to say anything definitive about the world we live in.   Design/Research methods: The article relies on professional publications, both within the field of economics and outside of it.   Conclusions/findings: There is much reason for humility, economic models and theories have hardly anything definitive to say about the empirical world, and there is a need for a more varied menu of theories and models and for a listening ear for the needs and fears of the population at large. The best we can do is discussing competing and conflicting views in a polite way. However, this requires a Sprachethik that looks more and more like an endangered species.   Originality/value of the article: Recent developments concerning the reach of economic models and theories are related to earlier discussions and a way forward is sketched

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.

Abstract Cognitive Gadgets offers a new, convincing perspective on the origins of our distinctive cognitive faculties, coupled with a clear, innovative research program. Although we broadly endorse Heyes’ ideas, we raise some concerns about her characterisation of evolutionary psychology and the relationship between biology and culture, before discussing the potential fruits of examining cognitive gadgets through the lens of active inference.
