La Incorporación de la Historia Local a la Enseñanza Formal de la Historia: Desafíos y Oportunidades

El presente artículo reflexiona en torno a la incorporación de la perspectiva de la "historia local" en la enseñanza formal de la Historia. Con ese propósito, se exploran los antecedentes de esta corriente disciplinaria, reseñando su desarrollo e identificando sus peculiaridades teóricas y metodológicas. Finalmente, se propone una identificación de los desafíos que representa su incorporación al curriculum escolar y los alcances que su adopción puede llegar a tener en la búsqueda de una renovación en la enseñanza de la Historia

On the accuracy of Latin American trade statistics: A nonparametric test for 1925

This paper proposes a nonparametric test in order to establish the level of accuracy of the foreign trade statistics of 17 Latin American countries when contrasted with the trade statistics of the main partners in 1925. The Wilcoxon Matched-Pairs Ranks test is used to determine whether the differences between the data registered by exporters and importers are meaningful, and if so, whether the differences are systematic in any direction. The paper tests for the reliability of the data registered for two homogeneous products, petroleum and coal, both in volume and value. The conclusion of the several exercises performed is that we cannot accept the existence of statistically significant differences between the data provided by the exporters and the registered by the importing countries in most cases. The qualitative historiography of Latin American describes its foreign trade statistics as mostly unusable. Our quantitative results contest this view.Latin America, statistical accuracy, international trade data, nonparametric methods, petroleum trade, coal trade.

Energy as an indicator of modernisation in Latin America by 1925

In absence of comparable macroeconomic indicators for most of the Latin American economies beyond the 1930s, this paper presents an estimate of the apparent consumption per head of coal and petroleum for 25 countries of Latin American and the Caribbean for the year 1925, doubling the number of countries for which energy consumption estimates were previously available. Energy consumption is then used as an indicator of economic modernisation. As a result, the paper provides the basis for a quantitative comparative analysis of modernisation performance beyond the few countries for which historical national accounts are available in Latin America.Energy consumption, modernisation, Latin America, petroleum, coal

Weld Distortion Prediction With Virtual Analysis For Practical Applications

The reduction in time and facilities involved in the partial elimination or mitigation of welding distortion is one of the key points for manufacturers. Welding distortion is influenced by the sequence and position of joints, the clamping configuration and the design of the assembly. For large complex assemblies, the range of these options may be large. Therefore the use of numerical simulations at an early stage of the product development process is valuable to enable a wide range of these factors to be explored with the aim of minimizing welding distortions before production commences. This thesis investigates two techniques for simulation of welding distortions based on shrinkage analysis and transient analysis. Both techniques are evaluated for an automotive assembly. The shrinkage simulations were built and solved using the Weld Planner, whereas the transient simulations were solved with Sysweld. The rapid simulation speed enabled a wide range of welding materials and clamping positions to be explored, leading to recommendations for reduction of the distortions. The solution times were found to be significantly lower for the shrinkage analysis than the transient analysis

Modern energy consumption and economic modernisation in Latin America and the Caribbean between 1890 and 1925

In the absence of comparable macroeconomic indicators for most of the Latin American economies before the 1930s, the apparent consumption of energy is used in this paper as a proxy of the degree of modernisation of Latin America and the Caribbean. This paper presents an estimate of the apparent consumption per head of modern energies (coal, petroleum and hydroelectricity) for 30 countries of Latin American and the Caribbean for 1890 to 1925, multiplying the number of countries for which energy consumption estimates were previously available. As a result, the paper provides the basis for a quantitative comparative analysis of modernisation performance beyond the few countries for which historical national accounts are available in Latin America.Energy consumption, economic modernisation, Latin America

Rainwater Catchment System At Walden West Outdoor Science School

Walden West Outdoor Science School is a science camp in the hills of Saratoga where children learn science as it relates to the environment and the importance of using sustainable practices. A full-scale bioswale was designed to capture and reuse the rainwater runoff from the main parking lot and lodge on the site. To encourage future implementation of the design as well as to provide a learning tool for future science camps, a model bioswale was built using materials required in actual bioswale construction. A synthetic water sample was developed to mimic the characteristics of rainwater runoff. The synthetic sample was applied to the model bioswale and water quality analyses were performed on the water collected from the bottom of the model in an attempt to exhibit the effectiveness of bioswales. In addition, a curriculum was created for the students at Walden West to teach them about bioswales and their effects on water quality
