W. J. SHEILS (editor), The Church and healing, (Studies in Church History, No. 19), Oxford, Basil Blackwell for the Ecclesiastical History Society, 1982, 8vo, pp. xxiv, 440, £19.50. This collection of essays represents a thoughtful, stimulating, and generally successful cooperative attempt by medical and ecclesiastical historians to study an important topic, the relationship between the Christi...

The key notion for modelling calendar systems and many other periodic temporal notion is the mathematical concept of a partitioning of the real numbers. A partitioning of R splits the time axis into a sequence of intervals. Basic time units like seconds, minutes, hours, days, weeks, months, years etc. can all be represented by partitionings of R with finite partitions. Besides the basic time un...

Marriage license books are documents that were used for centuries by ecclesiastical institutions to register marriage licenses. These books, that were handwritten until the beginning of the 20th century, have interesting information, useful for demography studies and genealogical research. This information is usually collected by expert demographers that devote a lot of time to manually transcr...

In De iustitia et iureLuis de Molina distinguishes between different meaningsof servitude and considers slavery to be licit ifit is practised within the framework of certain conditions. This article studies Molina's position, showing that precise definition conditions under which allows him limit legal scope this practice, denounce injustices slave trade, claim regulation political ecclesiastic...

This paper proposes to look at the interaction between miter and Indians of Archdiocese Mexico during Manuel Rubio y Salinas prelacy (1749-1765). Some most relevant reformist programs related Indigenous population are examined: exercise ecclesiastical justice, Hispanicization control over confraternities. The goal is show continuities changes in policy this archbishop; parishioner responses pro...

We show that if SAT does not have small circuits, then there must exist a small number of satisfiable formulas such that every small circuit fails to compute satisfiability correctly on at least one of these formulas. We use this result to show that if PNP[1] = PNP[2], then the polynomial-time hierarchy collapses to Sp2 ⊆ Σp2∩Πp2. Even showing that the hierarchy collapsed to Σp2 remained open p...

We characterize the collapse of Buss’ bounded arithmetic in terms of the prov­ able collapse of the polynomial time hierarchy. We include also some general model-theoretical investigations on fragments of bounded arithmetic.
