Construções euclidianas e o desfecho de problemas famosos da geometria

Construction techniques with ruler and the compasses, fundamental on Euclidean geometry, have been related to modern algebraic theories such as solving equations and extension of bodies from the works by Paolo Ruffini (1765-1822), Niels Henrik Abel (1802-1829) and Evariste Galois (1811-1832). This relation could provide an answer to some famous problems, from ancient Greece, such as doubling the cube, the trisection Angle, the Quadrature of the Circle and the construction of regular polygons, which remained unsolved for over two thousand years. Also important for our purposes are the notions of algebraic numbers, transcendental and the criteria for constructability, of those numbers. The objective of this study is to reconstruct relevant steps of geometric constructions with ruler (unmarked) and the compasses, from the elementary to the outcome buildings, in the nineteenth century, considering those mentioned problems.

La cocina de los venenos. Aspectos de la criminalidad en el Nuevo Reino de Granada, siglos XVII-XVIII

Durante los siglos XVII y XVIII se presentaron varias querellas ante el Tribunal de Justicia Criminal del Nuevo Reino de Granada, en las que se denunciaba que había personas que ejercían los oficios médicos sin tener títulos que los acreditaran como facultativos en las artes curativas. Por ese entonces, se creía que quienes utilizaban yerbas y conjuros como métodos terapéuticos, por lo general mujeres, debían ser juzgadas como yerbateras-envenenadoras, porque no pretendían curar sino matar a quien consumiera sus preparados. El texto establece que los procesos criminales por envenenamiento constituyen un prisma en el que convergen diferentes problemáticas del periodo colonial neogranadino, relacionadas con la salud, los oficios médicos, las enfermedades, las creencias mágico-religiosas, el ideal de mujer en la época, la delincuencia, y las dinámicas de las instituciones españolas, entre otras. De esta manera, se estudió cómo fue la relación entre los aspectos jurídicos, las leyes criminales (dictadas por la Corona) y las conductas “desviadas” (relacionadas con el crimen por envenenamiento) de los habitantes del Nuevo Reino de Granada, entre los siglos XVII y XVIII. Para ello se revistaron desde diferentes perspectivas, varios temas del mundo colonial neogranadino, relacionados con los rumores, la comidilla, los chismes y la importancia de la comunicación hablada en el virreinato; el problema de la honra, como una de las virtudes más sobresalientes de la época y las creencias de la cultura popular con relación al envenenamiento y los diferentes métodos curativos.

Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.
