The medieval ‘scientia' of structures: the rules of Rodrigo Gil de Hontañón
Medieval builders didn't have a scientific structural theory, however gothic cathedrals were not build without a theory. Gothic masters had a ‘scientia', a body of knowledge which permitted the safe design of their buildings. The nature of this theory has not only a historical or erudite interest; perhaps something could be learned from the true masters of masonry architecture.
Literary sources from the gothic period are scarce; in almost all we find structural rules to design the principal structural elements: walls, vaults (ribs and keystones) and, above all, buttresses. These rules (arithmetical or geometrical) conduced in most cases to a certain proportions independently of size, to geometrically similar designs (for example, the depth of a buttress is a fraction of the span). Very rarely, and this is the case with Rodrigo Gil, appeared arithmetical rules which lead to non-proportional designs (following Rodrigo's rule the buttresses become more slender in relation to the span as the size increases).
These rules were a means to register stable forms. Proportional rules are, as has pointed Professor Heyman, essentially correct. It is a problem of stability and not of strength. Non-proportional rules express a finer adjustment to some non-proportional design problems: buttress design for the thin domical cross vaults (bóvedas baídas), boss design for the vaults themselves, and wall design for towers. The rules were deduced empirically, give correct dimensions, but above all draw our attention to some significant facts of design which so far have remained unnoticed

Rodrigo Calderón de Aranda and the administrative correspondence in the time of Philip III
Rodrigo Calderón de Aranda resulta uno de los personajes clave del valimiento del duque
de Lerma y, por extensión, del reinado de Felipe III; de ahí que se le haya dedicado atención
desde diversos campos de estudio, sin embargo, ¿qué hay de su documentación?
En este sentido, el presente trabajo pretende ofrecer una visión general de la cultura escrita
del periodo y su relación con el poder, así como de su aplicación al mundo de la
Administración a través del desarrollo de la correspondencia administrativa en un periodo
en plena transición. Todo ello a través de este personaje, su labor política y su
documentación.Rodrigo Calderón de Aranda is one of the key figures in the reign of the Duke of Lerma and,
by extension, in the reign of Philip III; hence, attention has been devoted to him from various
fields of study, but what about his documentation?
In this sense, this paper aims to offer an overview of the written culture of the period and its
relationship with power, as well as its application to the world of the Administration through
the development of administrative correspondence in a period in full transition. All this
through this character, his political work and his documentation.Grado en Histori

Un long chemin semé d'objets cultuels: le cycle initiatique aranda
International audienceFrom Durkheim to Lévi-Strauss, through Mauss and many other authors, the founding texts of French anthropology have been deeply inspired by the ethnography of an Australian aboriginal group, the Aranda, particularly with regard to religion, kinship and totemism. Paradoxically, the reference works of Aranda anthropology, such as those of Spencer & Gillen, C. and T. Strehlow, have never been translated into French. Marika Moisseeff presents here a detailed analysis of the Aranda ethnographic material bequeathed by these authors, enriched by more current data on neighboring communities. In so doing, she revises certain classic, somewhat fixed conceptions that the French public too often adopts to consider the social organization and cosmology of Australian Aborigines. The author thus shows that the Aboriginal Dreaming refers less to past and mythical times than to a dynamic entity referring to space, to the very particular landscape of the Australian continent. Similarly, the categories of kinship and totemism respond less to an exclusively classificatory necessity than to a relational logic requiring the regeneration of links from one generation to the next. The unfolding of ritual life constitutes the framework of this rereading of the Aranda data. It takes us step by step through the initiatory itinerary of the individuals that leads them to melt into the Dream, weighted with their atemporal double, the ritual object that supports their spiritual identity.De Durkheim à Lévi-Strauss, en passant par Mauss et bien d'autres auteurs, les textes fondateurs de l'anthropologie française se sont profondément inspirés de l'ethnographie d'un groupe aborigène d'Australie, les Aranda, tout particulièrement en ce qui concerne la religion, la parenté et le totémisme. Paradoxalement, les ouvrages de référence de l'anthropologie aranda, tels que ceux de Spencer & Gillen, C. et T. Strehlow, n'ont jamais été traduits en français. Marika Moisseeff présente ici une analyse détaillée du matériel ethnographique aranda légué par ces auteurs, enrichie par les données plus actuelles portant sur des communautés voisines. Ce faisant, elle rénove certaines conceptions classiques, quelque peu figées, que le public français adopte trop souvent pour considérer l'organisation sociale et la cosmologie des Aborigènes australiens. L'auteur montre ainsi que le Rêve aborigène renvoie moins aux temps passés et mythiques qu'à une entité dynamique se référant à l'espace, au paysage si particulier du continent australien. De même, les catégories de parenté et le totémisme répondent moins à une nécessité exclusivement classificatoire qu'à une logique relationnelle exigeant la régénération des liens d'une génération à l'autre. Le déroulement de la vie rituelle constitue la trame de cette relecture des faits aranda. Il nous fait parcourir pas à pas l'itinéraire initiatique des individus qui les conduit à se fondre dans le Rêve, lesté de leur double atemporel, l'objet cultuel support de leur identité spirituelle
The Stability of Subsidized Childcare in Georgia
Georgia’s Childcare and Parent Services (CAPS) program provides scholarships for children in families with low incomes and in vulnerable circumstances to help them obtain high-quality childcare at a subsidized value. The scholarships are intended to subsidize childcare costs while parents/caregivers work or prepare themselves for work through school or training. The scholarships give families flexibility by allowing them to choose a care provider and type of care (subject to some restrictions). Stable childcare arrangements for families participating in the program are an important aspect of quality. In this technical report, Rodrigo Aranda and David C. Ribar use 2015 to 2020 CAPS program records to investigate stability in the program by examining continuous, uninterrupted periods (i.e., spells) of children holding CAPS scholarships, receiving subsidized care from the same provider, and holding scholarships but not using them. We find that most CAPS scholarship spells are stable, with nearly two-thirds lasting six months or more, 30% lasting a year or more, and 15% lasting two years or more. We also find that care arrangements are relatively stable, with only about a third of children ever changing providers. However, many children take breaks from their providers—often when they continue to hold scholarships. Nearly two-thirds of children have spells where they hold a scholarship but do not use it. Most spells of non-use are short and last about three weeks. Care arrangement spells tend to be shorter for older children and are stable across demographic characteristics, such as race and ethnicity. Many care arrangement spells end when families are required to renew their eligibility for CAPS services.
