Sociedad del conocimiento: herramienta de competitividad en el comercio internacional

The knowledge society was born to make way for a new model of social organization in which wealth is no longer measured in quantity of goods produced and / or possessed, or in natural resources and much less on holding money, Now the decisive factor for the production of wealth is only found in the new ideas that manage to be reflected in the role and then be applied to produce a useful improvement for humanity. The strategy of generating this string that provides value added to goods and processes is education, which today opens its doors to those who want to understand more about their own environment, this task is simplified in a world where virtuality in communications and media succeeds in widening the range of possibilities of access to such education. It is at this point where it is argued that the educational model of Colombia must take aim at encouraging the development of research and improve conditions to foster environments that encourage this taskLa sociedad del conocimiento nace para dar paso a un nuevo modelo de organización social en donde la riqueza ya no se mide en cantidad de bienes producidos y/o poseídos, ni tampoco en recursos naturales y mucho menos en la tenencia de dinero, ahora el factor decisivo para la producción de riqueza solo se encuentra en las nuevas ideas que logran ser plasmadas en el papel para luego ser aplicadas y producir una mejora útil para la humanidad. La estrategia de generar esta cadena que proporciona valor agregado a los bienes y procesos es la educación, que hoy en día le abre sus puertas a quien desee comprender un poco más acerca de su propio entorno, dicha tarea se simplifica en un mundo en el que la virtualidad en las comunicaciones y en los medios informativos logra ampliar el margen de posibilidades de acceso a dicha educación. Es en este punto en donde se plantea que el modelo educativo de Colombia debe apuntarle a incentivar el desarrollo investigativo y mejorar las condiciones para propiciar ambientes que motiven a dicha tarea

Protein Repeats from First Principles

Some natural proteins display recurrent structural patterns. Despite being highly similar at the tertiary structure level, repeating patterns within a single repeat protein can be extremely variable at the sequence level. We use a mathematical definition of a repetition and investigate the occurrences of these in sequences of different protein families. We found that long stretches of perfect repetitions are infrequent in individual natural proteins, even for those which are known to fold into structures of recurrent structural motifs. We found that natural repeat proteins are indeed repetitive in their families, exhibiting abundant stretches of 6 amino acids or longer that are perfect repetitions in the reference family. We provide a systematic quantification for this repetitiveness. We show that this form of repetitiveness is not exclusive of repeat proteins, but also occurs in globular domains. A by-product of this work is a fast quantification of the likelihood of a protein to belong to a family.Fil: Turjanski, Pablo Guillermo.

The Demand for Preventive Activities Among Older Adults and its Association With Medicare Expenditures

In recent years, certain health policy makers have emphasized the need for an increase in preventive services interventions as means to improve health outcomes and cut health care costs. Oftentimes, the debate around the purported benefits of prevention centers on the need to cut the costs of highly costly systems such as Medicare. However, little is known about the factors that might actually influence the demand for preventive services among older adults, neither do we know much about how the dynamic for the demand for prevention plays out among older adults within the context of a household. Moreover, there is little evidence to support the belief that all preventive activities necessarily translate in cost savings. This dissertation examines the theoretical and empirical factors that influence the demand for prevention at the individual and household level. It also analyzes the associations between a diverse set of preventive services and Medicare expenditures in older adults. Using a panel data set from the Health and Retirement study linked to Medicare claims data, I find evidence that while lifestyle prevention such as physical activity, non-smoking and normal weight status maintenance are negatively associated with Medicare expenditures at ages 65-69, clinical preventive activities such as flu shot, cholesterol screening, mammography, Pap smears test and prostate cancer screening have at best no effect on expenditures, at worst they are positively associated; yet these findings may be biased due to uncontrolled unobservables. Also, I find that education, risk aversion, and long term planning are significantly associated with a higher demand for all preventive services. Finally, I find large bargaining effects between household members whereby spouses initiate and terminate preventive activities together. This result leaves room for policy makers to take advantage of spillover effects in the design of interventions designed with the purpose of increasing the demand for prevention

Reflexões sobre a enfermagem desde a biopolítica: relações de poder e cuidado

Este ensayo tiene como objetivos reflexionar desde la perspectiva foucaultiana, el cuidado que se entrega y se enseña a los futuros profesionales y analizar las relaciones de poder en el ámbito de la enfermería y el vínculo con las personas “objetos de cuidado” desde un enfoque bioético. La metodología incorpora un análisis de textos desde la perspectiva foucaultiana en salud, una mirada retrospectiva sobre experiencias profesionales y la instalación de dispositivos de poder en enfermería. Se analizan fuentes relacionadas con la historia de enfermería y la formación profesional con énfasis en las relaciones profesores/estudiantes y enfermeros/pacientes. Se contrastan aspectos bioéticos y contextos profesionales. La enfermería ha normalizado la instalación de lógicas de control en la atención directa de personas y en el cuidado, lo cual además se transfiere a la formación de enfermeras y enfermeros. Actualmente, el pensamiento de enfermería se ha ampliado, independizado y adaptado a los contextos, lo que invita a visualizar desde una perspectiva más amplia el propósito del quehacer disciplinar y profesional, abriendo una mirada introspectiva que permita comprender, que el ejercicio de la enfermería desde lo cotidiano, perpetúa lógicas de subordinación y poder tanto en la atención directa como en los equipos de trabajo.This essay invites to a reflection, from the Foucauldian perspective, about the viewpoint of nursing-care delivery and teaching to future professionals, as well as the analysis of the relations of power in nursing and the link with people “caring objects” from a bioethical point of view. The methodology includes texts analysis from a Foucauldian perspective in health, a retrospective view about the experiences of professionals nurses and the installation of mechanism of power in nursing. Sources related to nursing history and the professional formation with emphasis on professor/student and nurse/patient relationship were analyzed. Bioethical aspects and professional contexts were compared. Currently nurses have normalized the existence of control mechanism within the direct attention of people and their care, which is transferred to the formation of nurses. Nowadays, nursing thoughts have been expanded, become independent and adapted to different contexts. This invites to use a broader perspective to observe the purpose of the discipline and the profession of nursing, using an introspective view that allows to understand that the nursing practice perpetuates subordination and power in both direct care teams and work teams.Este tema tem como objetivos reflexionar desde a perspectiva foucaultiana, o cuidado que se entrega e se ensina a os futuros professionais e analizar as relações de poder em o ámbito da enfermería e o vínculo com as pessoas “objetos de cuidado” desde um enfoque bioético.
