A sure house studies on the dynastic promise to David in the books of Samuel

The dissertation studies the texts mentioning or alluding to the dynastic promise to David in the books of Samuel; in the concluding further perspectives it also overviews the occurrences of the promise in the books of Kings; in the appendix, it comments on the "Law of the King" in Deut 17,14-20, the last verse of which may contain an allusion to the Davidic promise. The study engages with recent discussion on the history of the text of 2 Sam 7. In a detailed textual commentary, it treats with all the differences between the main textual witnesses of the chapter, and apart from the evaluation of the individual variants, it attempts to answer the question whether the differences are due exclusively to the process of transmission, or they are of literary character. Special attention is paid to the value of 1 Chr 17 for the reconstruction of the oldest text of 2 Sam 7; the author hopes that the conclusions of this part of the dissertation may prove to be of some importance for a more general study of the reception of Samuel in Chronicles. The subsequent literary analysis of 2 Sam 7 and the other passages referring to the dynastic promise to David leads to two alternative datings of Nathan's oracle and consequently two alternative redactional hypotheses trying to give account of the emergence of the examined passages. In the concluding perspectives, the function of the promise in Samuel is compared with the occurrences of the motif in Kings; this comparison leads to tentative conclusions concerning the development of the relation of the two books.

"Periodic crises": Clément Juglar between theories of crises and theories of business cycles

Business cycle theory is normally described as having evolved out of a previous tradition of writers focusing exclusively on crises. In this account, the turning point is seen as residing in Clément Juglar's contribution on commercial crises and their periodicity. It is well known that the champion of this view is Schumpeter, who propagated it on several occasions. The same author, however, pointed to a number of other writers who, before and at the same time as Juglar, stressed one or another of the aspects for which Juglar is credited primacy, including the recognition of periodicity and the identification of endogenous elements enabling the recognition of crises as a self-generating phenomenon. There is indeed a vast literature, both primary and secondary, relating to the debates on crises and fluctuations around the middle of the nineteenth century, from which it is apparent that Juglar's book Des Crises Commerciales et de leur Retour Périodique en France, en Angleterre et aux États-Unis (originally published in 1862 and very much revised and enlarged in 1889) did not come out of the blue but was one of the products of an intellectual climate inducing the thinking of crises not as unrelated events but as part of a more complex phenomenon consisting of recurring crises related to the development of the commercial world - an interpretation corroborated by the almost regular occurrence of crises at about 10-year intervals.

Low rates of X-Y recombination, not turnovers, account for homomorphic sex chromosomes in several diploid species of Palearctic green toads (Bufo viridis subgroup).

Contrasting with birds and mammals, most ectothermic vertebrates present homomorphic sex chromosomes, which might be due either to a high turnover rate or to occasional X-Y recombination. We tested these two hypotheses in a group of Palearctic green toads that diverged some 3.3 million years ago. Using sibship analyses of sex-linked markers, we show that all four species investigated share the same pair of sex chromosomes and a pattern of male heterogamety with drastically reduced X-Y recombination in males. Phylogenetic analyses of sex-linked sequences show that X and Y alleles cluster by species, not by gametolog. We conclude that X-Y homomorphy and fine-scale sequence similarity in these species do not stem from recent sex-chromosome turnovers, but from occasional X-Y recombination.

Iridophores and not carotenoids account for chromatic variation of carotenoid-basedcColoration in Common lizards (Lacerta vivipara).

Abstract Carotenoids typically need reflective background components to shine. Such components, iridophores, leucophores, and keratin- and collagen-derived structures, are generally assumed to show no or little environmental variability. Here, we investigate the origin of environmentally induced variation in the carotenoid-based ventral coloration of male common lizards (Lacerta vivipara) by investigating the effects of dietary carotenoids and corticosterone on both carotenoid- and background-related reflectance. We observed a general negative chromatic change that was prevented by β-carotene supplementation. However, chromatic changes did not result from changes in carotenoid-related reflectance or skin carotenoid content but from changes in background-related reflectance that may have been mediated by vitamin A. An in vitro experiment showed that the encountered chromatic changes most likely resulted from changes in iridophore reflectance. Our findings demonstrate that chromatic variation in carotenoid-based ornaments may not exclusively reflect differences in integumentary carotenoid content and, hence, in qualities linked to carotenoid deposition (e.g., foraging ability, immune response, or antioxidant capacity). Moreover, skin carotenoid content and carotenoid-related reflectance were related to male color polymorphism, suggesting that carotenoid-based coloration of male common lizards is a multicomponent signal, with iridophores reflecting environmental conditions and carotenoids reflecting genetically based color morphs.

Martin Lindhart (Ed.), Practicing the Faith. The Ritual Life of Pentecostal-Charismatic Christians, Berghahn Books, Oxford, 2011, 344 p.

This edited volume examines, from a ritual perspective, Pentecostal-Charismatic groups that are the fastest growing religious movements in the world today. The authors, who are anthropologists, ethnologists or sociologists (with one theologian) collected rich and diverse material on healing, deliverance, personal devotion, public engagement. Their work covers several regions such as Chile, South California, Fiji, Kenya, and Sweden. After an introduction by the editor, eleven chapters examine various issues relevant to the field. Overcoming the diversity of subjects, the unity of the volume is provided by the general ritual perspective and by the methodological implications of employing such a perspective.
