La voluntad de no creer
Hernández Iglesias,Manuel;
An??lisis filos?3fico , 2007,
Abstract: is it rational to believe something because one wants to believe it? prima facie it is not, for a rational belief is based on reasons, and the will to believe can be a cause, but not a reason for the belief. nevertheless, some attempts of causally self-inducing beliefs can be viewed as a sort of second-order rationality. this paper sketches a view of this second-order rationality based on davidson's thesis of the divided mind and ortega's distinction between ideas and beliefs. the uncomfortable conclusion of the discussion is that the ability to have second-order beliefs about our beliefs is what makes possible both self-criticism and self-improvement and dogmatism and self-corruption and that the possibility condition of rationality and freedom and of irrationality and alienation are the same.

Hernández Triana,Manuel;
Revista Cubana de Investigaciones Biom??dicas , 2008,
Abstract: health can be supported with consumption of diets differing in a amazing way in its fats, carbohydrates and proteins content, whose net production of atp is of 90%, 75%, and 55%, respectively. change of its ratios in diet has a narrow rank generating poor differences in energy decrease. thus, recommendations to control of body weight must be mainly based more on effect of micronutrients and energy ingestion than that showed in yielding of apt. these recommendations must to consider that the selection of nutrients isn't similar for maintenance or reduction of body weight. body glycogen, genetic load, and life styles may influence on fat oxidation, and fatty tissue dimension, so, fat ingestion and oxidation be proportional. in cuba, obesity increase is generated by cultural patterns, food habits, and by a combined effect of changes in nutrients ingestion and physical activity on glycogen levels and body fat oxidation. biological and social evolution present in our country has leads to more effective mechanisms for searching of not much healthy foods, and not toward decrease of food energy. a future and better availability of desirable foods leads to an excess weight body in more than 50% of adult subjects. these nutrition recommendations must to contribute to prevention of this increase
Requerimiento de energía alimentaria para la población cubana adulta
Hernández Triana,Manuel;
Revista Cubana de Higiene y Epidemiolog?-a , 2005,
Abstract: the requirement of food energy in adults is the amount of energy necessary to balance the energy output and to maintain the height, constitution, indicated and desired physical activity level and a good health status. the standing values for the cuban population were set by the institute of nuitrition in 1996. the new values of requirements for the cuban population starting from 2004 and the methodology for their estimation in population groups, based on height and the suitable weight for it in order to attain a body mass index of 21, are given in this paper. the new proposal has been made aimed at covering the nutritional requirements of this population group. attention has been focused on overweight and chronic diseases in the cuban population and the older adult. the values of food energy recommended to the adult population differ only 1 % from the previous ones and they have been structured according to the guidelines established by the fao/who/unu committee of energy experts in 2004.
Recomendaciones nutricionales para el ser humano: actualización
Hernández Triana,Manuel;
Revista Cubana de Investigaciones Biom??dicas , 2004,
Abstract: the nutritional recommendations of energy and nutrients, which are the basic working tool of nutrionists and health and economy workers and planners were updated . documents setting the guidelines on the amount of nutrients the population should receive to meet its requirements have been published at the international level since 1943. the nutritional recommendation refers to the amount of a certain nutrient capable of facilitating the normal functioning of the human metabolism in almost the totality of the population.the recommendations have practical ends and a merely population approach.they are regularly updated by international bodies in accordance with the results of the nutritional research. the recommendations made by the u.s. food and nutrition board, 2002, the fao/who/uno expert committees of energy and proteins, and the nutritional recommendations and food guides for the cuban population, 1996, were used as reference documents.
Notas sobre la configuración del mal en Platón
Hernández,Silvestre Manuel;
Revista de Filosofía , 2008,
Abstract: this article studies the aspects from which a ?concept of evil? in plato can be derived. stress is given to the intellection of good, identified by the trinomial being-order-truth, in overcoming the human contingency by means of episteme, and to evil as non-being. the hypotheses is sustained that evil exists as a counter-argument to the platonic ideal of an auto-sufficient life based on ethics and knowledge.

Revista Cubana de Higiene y Epidemiología , 2005,
Abstract: El requerimiento de energía alimentaria en adultos es la cantidad de energía necesaria para balancear el gasto energético y mantener el tama o, la composición corporal, el nivel de actividad física indicado y deseado y un buen estado de salud. Los valores vigentes para la población cubana fueron establecidos por el Instituto de Nutrición e Higiene de los Alimentos en el a o 1996. En este trabajo se ofrecen los nuevos valores de requerimientos que rigen para la población cubana a partir del a o 2004 y la metodología para su estimación en grupos poblacionales, basados en la talla corporal y el peso idóneo para esa talla, con el objetivo de alcanzar un índice de masa corporal de 21. La nueva propuesta ha sido establecida con el propósito de cubrir requerimientos nutricionales de este grupo de población. Especial consideración han recibido la prevalencia de sobrepeso corporal y las enfermedades crónicas en la población cubana y en el adulto mayor. Los valores de energía alimentaria recomendados para la población adulta difieren solo en un 1 % de los anteriores y se han estructurado de acuerdo con los lineamientos del Comité de Expertos de Energía de FAO/OMS/UNU del a o 2004.

Recomendaciones nutricionales para adultos con sobrepeso corporal Nutrition recommendations for adults presenting with excess weight

Abstract: La salud puede mantenerse con el consumo de dietas que difieren asombrosamente en su contenido de grasas, carbohidratos y proteínas, cuya producción neta de ATP es 90%, 75% y 55% respectivamente. El cambio de sus proporciones en la dieta tiene un rango estrecho que genera despreciables diferencias en la disipación de energía. Por ello, las recomendaciones para el control del peso corporal deben basarse más en el efecto de los macronutrientes sobre el consumo alimentario y la ingestión de energía, que en el que muestran sobre el rendimiento de ATP. Ellas también deben considerar, que la selección de nutrientes no es similar para mantenimiento o reducción del peso corporal. Glucógeno corporal, carga genética y estilos de vida influencian la oxidación de grasa y la dimensión de tejido adiposo, de forma tal, que la ingestión y la oxidación de grasa resulten proporcionales. El incremento de la obesidad en Cuba esta generado por patrones culturales, hábitos alimentarios y por un efecto combinado de los cambios en la ingestión de nutrientes y en la actividad física sobre los niveles de glucógeno y la oxidación de grasa corporal. La evolución biológica y social en Cuba ha conducido hacia mecanismos más efectivos en la búsqueda de alimentos poco saludables y no hacia la reducción de la energía alimentaría. Una futura mejor disponibilidad de alimentos deseables conducirá a sobrepeso corporal en más del 50% de la población adulta. Estas recomendaciones nutricionales deben contribuir a la prevención de ese incremento Health can be supported with consumption of diets differing in a amazing way in its fats, carbohydrates and proteins content, whose net production of ATP is of 90%, 75%, and 55%, respectively.

Recomendaciones nutricionales para el ser humano: actualización Nutritional recommendations for the human beign: updating

Revista Cubana de Investigaciones Biom??dicas , 2004,
Abstract: Se realizó una actualización de las recomendaciones nutricionales de energía y nutrientes, los cuales constituyen el instrumento básico de trabajo de nutricionistas, trabajadores y planificadores de salud y economía. Desde el a o 1943 se han publicado al nivel internacional documentos que trazan las pautas de la cantidad de nutrientes que debe ser ingerida por poblaciones para satisfacer sus requerimientos. Se entiende por recomendación nutricional la cantidad de un nutriente determinado capaz de facilitar un normal funcionamiento del metabolismo del ser humano en casi la totalidad de una población. Las recomendaciones tienen fines prácticos y un enfoque meramente poblacional. Estas recomendaciones se actualizan con regularidad por organismos internacionales de acuerdo con los resultados de la investigación nutricional. Para este trabajo se han tomado como documentos de referencia las recomendaciones del Consejo de Alimentación y Nutrición de los EE.UU., 2002, los Comités de Expertos de Energía y Proteínas de FAO/OMS/UNU, 2004 y las Recomendaciones Nutricionales y Guías de Alimentación para la Población Cubana, 1996.
