Abstract: the incipient use of internet in rural areas and there was the assumption that the low educational level, older producers, the lack of infrastructure and computer hardware, affect the interest of producers to know and use the medium of communication. diagnosis was performed to identify factors that determine the use of these electronic media in rural areas of the state of aguascalientes. in april 2008; 81 producers were interviewed by sampling method in "bola de nieve". sociodemographic characteristics were identified: gender, age, education, occupation and aspects of computer use, email and internet. negative correlation was found between the age of producers and computer use (r2= -0.43920) and high positive correlation with educational level (r2= 0.74248), and the need for training in the internet use (r2= 0.89646). notwithstanding the alleged cultural barriers and lack of infrastructure and computer equipment in rural areas, it was possible in three workshops to train 37 farmers in the management of a computer, email and internet. under the light of the results, contrary to the assumption that the internet has no rural penetration, it was found in the area of study, that there is interest in using electronic means of communication as well as the availability of infrastructure (10 000 digital community centers nationwide) so there is a great opportunity for internet use in the transfer of information on web pages, email, video conferencing, distance learning, discussion forums, among other tools and applications like a cost-effective to enhance persona l communication, group and institutional development and strengthening rural families.

Revista mexicana de ciencias agrícolas , 2011,
Abstract: Los científicos(as) agropecuarios(as) están influenciados(as) por diversos factores para definir su enfoque de investigación. El objetivo de este trabajo fue identificar aspectos demográficos y profesionales, institucionales e influencias internas-externas asociados al enfoque sostenible, ecologista o productivista de los científicos(as) en Aguascalientes, México en 2008. Los enfoques fueron sometidos a un análisis de correlación con 44 factores de influencia. El enfoque sostenible correlacionó positivamente con la especialidad, la solución de problemas de interés institucional, investigación en terrenos de productores e investigación en sistemas de producción y negativamente con investigación básica y biotecnología. El enfoque ecologista correlacionó positivamente con la opinión del grupo interdisciplinario en la definición del problema a investigar. El enfoque productivista correlacionó positivamente con la especialidad, opinión del usuario y colegas en la definición del problema, estudios en terrenos de productores y en la estación experimental, trabajos por componente tecnológico y con la objetividad del investigador(a), y negativamente con la disciplina ecología. El modelo de regresión logística para la investigación con enfoque sostenible se explica por el origen de los investigadores(as), estancias de investigación, tipo de institución, fuente de financiamiento, investigación por demanda del usuario y prioridad institucional, trabajo interdisciplinario, estudios tanto en sistemas de producción como por componente tecnológico. El modelo ecologista se explica por las estancias de investigación, aprobación del proyecto por un comité técnico, investigación en terrenos de productores, trabajo interdisciplinario y estudios en sistemas de producción. El modelo productivista tuvo las variables explicatorias tipo de institución y trabajo en sistemas de producción.

Estudios Geográficos , 2003,
Abstract: From 1936 to 1939 the cartographic services of the Republic, and the cartographic section of the Franco's General Staff, carried out an enormous task in cartography in order to fulfil the requiriments of the Spanis Civil War. In spite of his importance, those maps are poorly known. So the persons in charge of them. After presenting a general description of Spanish official cartography before 1936, this article explains how the Republic solved the problems of map production, and describes the maps employed by the Republican Army. A forthcoming paper will present the task developed by the cartographers of General Franco. [es] Desde 1936 a 1939 los servicios cartográficos de la República, y los del Estado Mayor del general Franco, realizaron un enorme esfuerzo para atender las necesidades cartográficas impuestas por la guerra civil. Pese a su importancia, tales mapas han sido muy poco estudiados, ignorándose los responsables de su formación. Tras presentar un panorama general del estado de la cartografía oficial espa ola antes de julio de 1936, este artículo explica cómo abordó la República los problemas de producción cartográfica durante la guerra, y describe los mapas empleados por el ejército republicano. Un artículo próximo se ocupará de la labor realizada por los cartógrafos del ejército franquista. [fr] Depuis 1936 à 1939 les services cartographiques de la Répubhque et les de l'état Major du général Franco, accompliren un énorme effort pour satisfaire les nécessites cartographiques imposés par la guerre civile. Malgré leur importance, ces cartes ont été peu étudiés, et les responsables de leur formation sont igonorés. Après la presentation d'une panorama général sur l'état de la cartographie officielle espagnole avant juillet de 1936, cette article explique comme la République résolu les problèmes de production cartographique pendant la guerre, et décrive les cartes utilisisés par l'armée républicaine.

Country-Specific Dynamic Optimal Capital Income Tax Rate  [PDF]
Kazunobu Muro
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.23045
Abstract: The empirical tax rate on capital income ranges between 0.4 and 0.6 in OECD countries. This paper presents the optimal taxation problem in an one-sector dynamic general equilibrium model where the government is confronted with fiscal constraint (the ratio of government expenditure to GDP is exogenously given) while households and firms do not recognize the fiscal constraint. We derive analytically the positive optimal tax rates on capital income. Under the fiscal constraint, the optimal tax rate on capital income depends on the discount rate, the rate of capital depreciation, and the ratio of government spending to GDP. Our model can generate the country-specific optimal tax rate on capital income (0.2 to 0.4). Thus, this paper insists that the empirical data of tax rates in OECD countries are higher than the results predicted by our model.
