2008-04-01

Resumen en español Actualmente las universidades esperan jugar un nuevo papel en la sociedad además de investigar y enseñar, aplicar la “tercera misión” de desarrollo socioeconómico. Por lo cual, las universidades desempeñan un papel importante en el fortalecimiento de la creación de empresas a través del entrenamiento en planes de negocios. Un plan de negocios es un documento que resume cómo un emprendedor creará una organización para explotar una oportunidad comercial. Prepara (mas) r un plan de negocios requiere de una gran cantidad de conocimientos en diferentes disciplinas: finanzas; gestión humana, de derechos de propiedad intelectual, de cadenas de abastecimiento y de operaciones y mercadeo, entre otras. En este artículo se presenta una herramienta computacional que sirve como soporte en la elaboración de un plan de negocios, desde la perspectiva colombiana, identificando las etapas más relevantes tenidas en cuenta por entidades nacionales que tienen mayor trayectoria en el apoyo a la creación y consolidación de empresas. Para desarrollar el software se hizo énfasis en las etapas de análisis, diseño e implementación del ciclo de vida de desarrollo de sistemas. Durante la etapa de análisis fue importante la revisión de la literatura sobre planes de negocio teniendo en cuenta el caso colombiano. Resumen en inglés Currently, universities are expected to play a new role in society, in addition to research and teaching, by applying a ‘third mission’ of socio-economic development. Also universities play an important role in encouraging entrepreneurship through training for business plan. Business plan is a document that summarizes how an entrepreneur will create an organization to exploit a business opportunity. Preparing a business plan draws on a wide range of knowledge from many (mas) different business disciplines: finance, human resource management, intellectual property management, supply chain management, operations management, and marketing, among others. This article presents a computational tool that serves like support in the elaboration of a business plan from the Colombian perspective identifying the most outstanding stages kept in mind by national entities that have bigger trajectory in the support to the creation and consolidation of companies. Special emphasis was made in the stages of analysis, design and implementation of the Systems Development Life Cycle to develop the software. During the analysis stage it was important the revision of the literature about business plans keeping in mind the Colombian case.

Resumen en español El establecimiento de redes de áreas marinas protegidas (AMP) ecológicamente representativas es una importante herramienta de manejo con que se cuenta para proteger la biodiversidad y regular el uso de los recursos naturales marinos y costeros. Este trabajo tuvo como objetivo principal aportar elementos para el futuro diseño de una red de AMP para el norte del Caribe continental colombiano. Con la participación de expertos nacionales se identificaron 51 objetos de con (mas) servación (OdC) a diferentes niveles de organización biológica (sistemas ecológicos, comunidades ecológicas relevantes y especies) y sitios de importancia arqueológica, histórica y cultural indígena. Para cada uno de estos objetos se definieron metas de conservación cuantitativas por estrato o sistema costero (Tayrona, Palomino y Guajira), a partir de la evaluación de cuatro criterios (tipo de objeto, abundancia, condición actual y vulnerabilidad). Las metas finales determinadas para cada OdC fueron de ≤ 10, 30, 60 y 100%. Por último, a través de un sistema soporte de decisiones (SSD) llamado MARXAN, se identificó un portafolio con 63 sitios prioritarios de conservación equivalentes a un área de 129964 ha, de las cuales 71971 ha corresponden a 32 sitios considerados para ser parte de la red, al ser aplicados sobre estos criterios ecológicos de representatividad, heterogeneidad de hábitats, naturalidad y etapas de vida vulnerables. Este conjunto de áreas constituye una guía para una futura "planificación de sitio" más detallada, donde se deberán aplicar criterios sociales, económicos y político-administrativos con el fin de proponer el tipo de categoría de manejo más adecuada y estrategias de conservación específicas, para implementarlas en el corto y mediano plazo. Los sitios identificados adyacentes a las áreas protegidas existentes deberán ser tomados en cuenta como elementos de análisis para ampliar y re-alinderar dichas áreas hacia la porción marina principalmente. Resumen en inglés Ecological representative marine protected areas (MPA) establishment is an important management tool for natural marine and coastal resources use regulation and biodiversity protection. Through a systematized selection process using MARXAN decision support system (DSS), the first Colombian Northern Caribbean MPA network was designed. Fifty-one conservation targets at different biological organization levels (ecosystems, communities and species) as well as archeological, h (mas) istorical, and indigenous cultural important sites were identified based on national expert knowledge. Target and coastal systems (Tayrona, Palomino, and Guajira) quantitative conservation goals were established using four criteria: type, abundance, natural condition, and vulnerability. Conservation goals ranged between ≤ 10, 30, 60, and 100%. A portfolio with 63 priority conservation sites, equivalent to an area of 129964 ha, was identified. Based on their high representativeness, habitat heterogeneity, naturalness, and vulnerable life stages 32 sites (71971 ha) were selected above all to be included in the MPA network. Follow up detailed "planning site" is now required to identify boundaries, short and middle time conservation strategies and adequate national category management type proposal. Priority conservation sites adjacent to existing protected areas are suggested as extendable areas over the submerged boundaries.

¿La bioética en la educación ambiental?/ The environmental education in the bioethics

Cuenca, Roberto E
2006-12-01

Resumen en español Introducción: En el área del medio ambiente, se ha percibido la bioética como una interdisciplina en la construcción de un pensamiento crítico, que debería concluir en un saber ambiental con ética y en un planteamiento epistemológico donde se reafirmen los valores existenciales y axiológicos, para finalizar analizando los derroteros de la educación ambiental. Objetivos: Demostrar cómo la bioética reivindica los valores del humanismo y plantear la educación am (mas) biental como una oportunidad de acción y generación de acciones en el desarrollo sostenible de las comunidades colombianas. Metodología: Mediante revisión bibliográfica, se elaboró un ensayo acerca de la relación de la bioética con la educación ambiental, en cuanto a los aspectos del ambiente, el desarrollo socioeconómico y la pedagogía ambiental. Resultados: Se realizaron descripciones acerca del concepto holístico en el medio ambiente; conceptualización sobre ética ambiental; conceptualización acerca del desarrollo sostenible, la globalización y la sustentabilidad; y conceptualización acerca de la educación ambiental y la bioética. Conclusiones: Del análisis realizado hay un primer epílogo que conduce a asumir la responsabilidad por nuestro accionar en el mundo y ser capaces de entender que la calidad de vida alcanza su plenitud, cuando se trasciende desde la conciencia individual hacia una forma de conciencia capaz de sentir como propia no sólo la necesidad sino, la de todo otro ser humano y de toda otra forma de vida. Y un segundo epílogo en el plantear estrategias de una educación ambiental, diferentes a las tradicionales, como una evolución hacia la educación para la sostenibilidad, sobre el cómo continuar el desarrollo al mismo tiempo que se protege, preserva y conservan los sistemas de soporte vital del planeta. Resumen en inglés Introduction: In the area of the environment, it has been perceived the Bioethics like an interdisciplinary in the construction of a critical thought that should conclude in an environmental knowledge with ethics and in a position epistemologist where the existential values and axiological are reaffirmed, to conclude analyzing the courses of the environmental education. Objectives: To demonstrate how the Bioethics claims the values of the humanism and to outline the Envir (mas) onmental Education as an action opportunity and generation of actions in the sustainable development of the communities of our region. Methodology: By means of bibliographical revision, a rehearsal was elaborated about the relationship of the Bioethics with the Environmental Education, as for the aspects of the atmosphere, the socioeconomic development and the environmental pedagogy. Results: They were carried out descriptions about the Holistic concept in the environment; conceptualization on Environmental Ethics; conceptualization about the Sustainable Development, the Globalization and the Sustainability; and conceptualization about the Environmental Education and the Bioethics. Conclusions: Of the carried out analysis we have a first epilogue that drives to assume the responsibility for our to work in the world and being able to understand that our quality of life reaches its fullness, when we transcend from our individual conscience toward a form of conscience able to not feel as own alone our necessity but, that of all other human being and in all other way of life. And a second epilogue in outlining strategies of an Environmental Education, different to the traditional ones, like an evolution toward the Education for the Sustainability, on the as continuing the development at the same time that it is protected, it preserves and they conserve the systems of vital support of the planet.

Ácidos grasos omega-6 y omega-3 en la nutrición perinatal: su importancia en el desarrollo del sistema nervioso y visual/ Omega-6 and omega-3 fatty acids in perinatal nutrition: their importance in the development of the nervous and visual systems

Valenzuela B, Alfonso; Nieto K, Susana
2003-03-01

Resumen en español Los ácidos grasos poliinsaturados de cadena larga omega-6; ácido araquidónico, y omega-3; ácido docosahexaenoico, son fundamentales en la formación de la estructura y en la funcionalidad del sistema nervioso y visual de los humanos. Ambos ácidos grasos constituyen más del 30% de la estructura lipídica del cerebro y de los conos y bastoncitos de la retina. Se estima que la función de estos ácidos grasos es aportar un alto grado de fluidez a las membranas celulare (mas) s, permitiendo el movimiento de proteínas en su superficie y dentro de la bicapa lipídica. Estos ácidos grasos se forman a partir de precursores de menor tamaño de cadena: el ácido linoleico da origen al ácido araquidónico, y el ácido alfa linolénico al ácido docosahexaenoico. Esta transformación ocurre principalmente en el hígado. Actualmente se estima que el feto, durante el último tercio del período gestacional, y el recién nacido, durante los primeros 6 meses de vida, requieren de un gran aporte de ácido araquidónico y de ácido docosahexaenoico, debido a que la velocidad de transformación de los precursores a nivel hepático no es suficiente para cubrir los requerimientos metabólicos de estos ácidos grasos. Es la madre quien los aporta a través del transporte placentario durante la gestación y a través de la leche durante la lactancia. Este aporte proviene de las reservas tisulares de la madre, de su actividad biosintética y del aporte nutricional de los ácidos grasos precursores. De esta forma, el adecuado aporte dietario de los ácidos grasos precursores o ya preformados es de vital importancia para la formación del tejido nervioso y visual. Se han observado alteraciones en la funcionalidad de estos tejidos en lactantes y niños que no han recibido un aporte adecuado de ácidos grasos omega-6 y omega-3 durante la gestación y en los primeros meses de vida. Actualmente se sugiere que las fórmulas de reemplazo o de complemento a la leche materna sean suplementadas, ya sea con los ácidos grasos omega-6 y omega-3 ya preformados, o con sus precursores Resumen en inglés The large chain polysaturated fatty acids omega-6; arachidonic acid, and omega-3; docosahexaenoic acid, are fundamental in the formation of the structure and the function of the human nervous and visual systems. These fatty acids form more than 30% of the lipid content of the brain and of the cones and rods of the retina. Their function is to provide a high grade of fluidity to the cell membrane, permiting the movement of proteins on the surface and within the lipid bilay (mas) er. These fatty acids are formed from smaller chain precursors principally in the liver, linoleic acid going to form arachidonic acid and linolenic acid forming docosahexanic acid. During the third trimester of pregnancy and the first 6 months of life large amounts of both fatty acids are needed. Hepatic production is not sufficient to meet the demand of these fatty acids, and additional support is needed, by transplacental transfer during pregnancy and from the maternal milk thereafter. This comes from the mothers tissue reserves, biochemical synthesis in the maternal liver and dietary support in the form of fatty acid precursors. Thus the dietary content of precursor and formed fatty acids are vitally important for the formation of the nervous and visual systems. Alterations in the function of these 2 systems in children who have not received an adequate intake of omega-6 and omega-3 fatty acids have been demonstrated. It is suggested that milk formulas are supplemented with omega 6 and 3 fatty acids or their precursors

La otra migración. Historias de discriminación de personas que vivieron con VIH en México/ The other migration. Histories of discrimination of people who lived with HIV in Mexico

Hernández-Rosete Martínez, Daniel
2008-08-01

Resumen en español La migración mexicana a Estados Unidos se ha interpretado como un proceso demográfico que existe en respuesta al empobrecimiento y a la polarización económica en México. Aunque la desarticulación económica y el abandono de las regiones rurales de México persisten como factores de expulsión de población, la migración de mexicanos muestra cambios recientes en las causas que la originan. La violencia familiar, por ejemplo, aparece como un detonante importante de l (mas) a incorporación de la mujer en los flujos migratorios, particularmente es el caso de zonas rurales del país. La homofobia es otro referente que, relacionado a los crímenes de odio, parece generar un nuevo orden de migración hacia Estados Unidos. No obstante que la violencia empieza a ser reconocida y vista sociológicamente como un factor de expulsión migratoria, en México es un fenómeno que hasta ahora se ha explorado poco. En este trabajo se analizan la violencia sexual y la discriminación como detonantes de un fenómeno migratorio emergente entre grupos de población homosexual. Se trata de un estudio cualitativo de tipo fenomenológico con el que se exploraron los universos de sentido y significado por medio de las historias de vida de migrantes transgénero y transexuales que viven con VIH en San Diego. El trabajo de campo se realizó en agosto de 2003 en condados de San Diego, California, en Estados Unidos. Se realizaron entrevistas y observaciones etnográficas en tres regiones geográficas de la ciudad donde se detectó la presencia de vecindarios de migrantes transgénero y transexuales de origen latinoamericano. En este artículo se describen precisamente las historias de personas transgénero y transexuales que se infectaron de VIH-sida en México. Para estas personas, la migración se convirtió en un recurso para atender su derecho a la salud e incluso para conservar la vida. El objetivo de este artículo es dar cuenta de las formas de agresión física y de discriminación que llevaron a los entrevistados a solicitar asilo político en San Diego, California. Las narraciones permiten comprender que en México la transfobia es una forma de violencia sexual que, ligada a la construcción social de la masculinidad dominante, existe a partir del miedo social a la homosexualidad como el basamento que legitima la discriminación, la persecución y la agresión de personas transgénero y transexuales. Un aspecto que parece recrudecer estas formas de violencia es la aparición de infecciones sexualmente transmisibles de tipo viral. De hecho, la historia de las enfermedades infecciosas muestra que homosexuales, trabajadoras sexuales y migrantes son figuras que aparecen de manera recurrente en el imaginario colectivo como responsables del origen de las epidemias. En el contexto global actual destaca la construcción del transgénero como víctima propiciatoria del VIH/sida. En México, esta coyuntura parece reforzar los esquemas de odio social en contra de las personas homosexuales que son VIH positivas, quienes pueden llegar a vivir con el estigma social de quien cree que la infección es un castigo meritorio. La discriminación y la violencia sexual que describen las informantes tiene que ver con la triple estigmatización (por ser poblaciones móviles, por ser transgénero y además por vivir con VIH). Se trata de un sistema de estigmatización que no sólo afecta la calidad de vida al excluirles laboral y jurídicamente, sino que impide reconocerles como sujetos de derecho a la salud, especialmente en materia de acceso a medicamentos antirretrovirales y de atención médica relativa al control del VIH/sida. Es necesario desarrollar un modelo de sensibilización dirigido a personal médico y, en general, de los sistemas de salud sobre la diversidad de prácticas e identidades sexuales y hacer énfasis en los derechos a la salud sexual y mental de las personas que viven con VIH, sin importar su preferencia sexual y de género. Resumen en inglés Mexican migration to the United States has been attributed to the poverty and economic polarization in Mexico. Although the dismantling of the peasant economy persists as a factor in demographic displacement, there have been recent changes in the causes that provoke the migration of Mexicans. Family violence, for example, appears as an important motivator in pushing women into the migratory flow, especially in rural areas of the country where women's sexual and reproducti (mas) ve rights appear to be less respected. Homophobia is another point of reference which, along with hate crimes, generates a new category of migration to the United States. Although violence is beginning to be recognized and viewed sociologically as a factor in migratory displacement, it is a phenomenon that has been little explored in Mexico until now. This article proposes to analyze sexual violence and discrimination as motivators of an emerging migratory phenomenon among transgender and transsexual groups within the Mexican population. The article is based on a qualitative study which explored the universes of sense and meaning through the stories of four Mexican women, three transgender and one transsexual, infected with HIV-AIDS in Mexico and who are currently seeking political asylum in San Diego, California. The fieldwork was done between August and September 2003 in San Diego County. Interviews and ethnographic observations were carried out in three geographic regions in the city where neighborhoods of transgender and transsexual migrants of Mexican origin were detected, as well as Non-Governmental Organizations (NGOs) that provide medical and psychological care to undocumented migrants of Latin American origin who live with HIV/AIDS: Northern Region: Carlsbad and Rancho Bernardo; Central Region: North Hill Park and Balboa Park; Southern Region: San Ysidro and Imperial Beach. The article provides anthropological data regarding the contexts, practices and magnitude of rejection and violence that the subjects suffered in Mexico. Four settings are emphasized: family life, interaction in the streets, the relationship with police and the relationship with health services related to caring for HIV/AIDS. To support the analysis it was considered advisable to resort, on the one hand, to phenomenology as a methodological approach to daily life and, on the other hand, to semiotics, where culture is understood as the expression of symbolic forms and objectivizations of sense and meaning that exist in the context of asymmetrical social relationships. This theoretical framework allowed us to postulate that sexual violence is a structural process based on asymmetrical power relationships and that it implies social norms and ideologies of male hegemony that contribute to the social acceptance of violent practices against transgender and transsexual men, which can make them go unnoticed in the community. For the interviewees, migration became a resort for asserting their right to health care, and even a means to preserve their lives. In Mexico, their presence in public places would frequently provoke attacks, scorn and mockery, which could lead to physical and emotional wounds. Civil society is not the only source of violence against transsexual and transgender individuals. Some police organizations systematically persecute them and submit them to violence. The harassment of homosexuals is routine practice among police officers. Their physical appearance is interpreted as a moral misdemeanor. Under this argument, they can become the victims of a complex range of abuses and humiliations that include blackmail or extortion and can lead to physical assault and sexual violence. This last type of aggression is one of the most dangerous because it implies a homosexual conduct on the part of the aggressor. Because there is a risk that his victim might press charges, the violence exercised against the transgender individual by the aggressor may be aggravated, which initiates a cycle of territorial mobility linked to exile because of the fear of being killed. Violence against transsexuals is reinforced by Mexican laws and bureaucratic procedures, which only recognize two genders and thus make it more complicated for transsexuals to prove their legal right to initiate proceedings or a lawsuit. These legal-bureaucratic loopholes help make the aggressor's impunity acceptable and his violations socially invisible. The stories make it possible to understand that in Mexico transphobia is a specific form of sexual violence which, linked to the social construction of male dominance, exists out of social fear of homosexuality as the foundation that legitimizes discrimination, hate, persecution and aggression against transgender and transsexual individuals. One aspect that seems to intensify these forms of violence is the appearance of sexually transmitted viral infections. In fact, the history of infectious diseases shows that homosexuals, sexual workers and migrants appear over and over again in the collective imagination as those responsible for the origin of epidemics. In today's epidemiological context, transgender is seen as a scapegoat for HIV/ AIDS. In Mexico, this situation appears to reinforce the preconceptions of social hatred against transgender persons who are HIV positive, who may end up living with the social stigma of those who believe that the infection is fitting punishment. The evidence suggests that, when transgender individuals are HIV carriers, discrimination against them is worse. The prejudice of medical personnel and the financial inability of health institutions to treat HIV/AIDS lead to precarious care and, occasionally, denial of access to antiretroviral medications. Ethnography suggests that violence against transsexuals is not eliminated when they immigrate to the United States. They experience less aggression than in Mexico, but in the United States they suffer racial and job discrimination. The benefit resides in that, despite their undocumented status, they have free access to antiretroviral drugs and to psychological care offered by the NGOs in San Diego that assist persons infected with HIV/AIDS. The discrimination and sexual violence described by those interviewed amount to a triple stigmatization (because they are itinerant populations, because they are transgender and because they live with HIV). This is a system of stigmatization that not only affects their quality of life by excluding them from jobs and the legal system, but also because it keeps them from being recognized as subjects with rights to health care, especially with regard to access to antiretroviral drugs and medical care related to control of HIV/AIDS, decisive factors which trigger the decision to migrate. This paper suggests the development of a model aimed at making medical practitioners and, in general, health systems personnel more aware of the diversity of sexual practices and identities and emphasizes the right to sexual and mental health care for individuals who live with HIV, regardless of their sexual preference or gender. It is fundamental to develop policies that will prevent the stigmatization and discrimination of persons with HIV and that will recognize the right to health care among populations that have been stigmatized historically.

La evaluación de los valores humanos con el Portrait Values Questionnaire de Schwartz/ Human values assessment with Schwart's Portrait Values Questionnaire

Castro Solano, Alejandro; Nader, Martín
2006-12-01

Resumen en español El estudio de los valores puede ser abordado desde múltiples perspectivas (filosófica, psicológica, sociológica, etc.). En Psicología, el análisis de las orientaciones valóricas de los individuos ha cobrado especial importancia a partir de las conceptualizaciones de Schwartz (1992, 2001) quien verificó una estructura de diez valores (Poder, Logro, Hedonismo, Estimulación, Autodirección, Universalismo, Benevolencia, Tradición, Conformidad y Seguridad), los cuale (mas) s se organizan en cuatro bipolaridades (Autotrascendencia, Autopromoción, Conservación y Apertura al cambio) en más de 60 países, dando soporte empírico a la clasificación de los valores humanos. Este estudio tiene como objetivos: (a) adaptar y validar el Portrait Values Questionnaire (PVQ) de Schwartz (1992, 2001) y (b) verificar si existen diferencias individuales según dos contextos objeto de estudio (civil y militar) y según sexo y edad. Se recogieron datos de una población argentina (N = 692) en tres contextos diferentes: (a) población civil (n = 471), (b) oficiales militares (n = 97) y (c) cadetes (n = 124). El estudio permitió verificar parcialmente la estructura de los valores propuestos por el autor. La fiabilidad del PVQ resulta muy adecuada en los tres contextos estudiados. Asimismo se pudo verificar que los civiles están más orientados hacia el logro de objetivos personales (Autopromoción) y la independencia para decir y hacer lo que uno quiere (Apertura al cambio), mientras que los militares están más orientados hacia los valores relacionados con el mantenimiento del orden social, la seguridad, la conservación de las tradiciones (Tradición y Conformidad). Por otra parte, los resultados mostraron que no existen diferencias en las orientaciones valóricas según sexo y edad. Resumen en inglés The study of human values can be approached from multiple perspectives (philosophical, psychological, sociological, etc.). In Psychology, the analysis of individual differences on value orientation has grown exponentially since Schwartz's works (1992, 2001) who verified a structure of ten universal values (Power, Achievement, Hedonism, Stimulation, Self-direction, Universalism, Benevolence, Tradition, Conformity and Security) which are organized in four bipolarities (Self (mas) -transcendence, Self-enhancement, Conservatism and Openness to change). Influenced heavily by Rokeach (1973), Schwartz's theory defines values as desirable, trans-situational goals, varying in importance, that serve as guiding principles in people's lives. The crucial aspect that distinguishes one value from another is the type of motivational goal it expresses. Schwartz derived a typology of different value contents by reasoning that values represent in the form of conscious goals three universal requirements of human existence: biological needs, coordinated social interaction requisites and group survival and functioning demands. There is substantial, cross-cultural support for the distinctiveness of this ten-type research from more than 60 countries. A specific value represents a type of action that when attained, promotes the central goal of the type. In addition to propositions regarding the content of values, the theory specifies dynamic relationships among the types of values. Actions taken in pursuit of each type of value have psychological, practical and social consequences that may clash or be compatible with the pursuit of other value types. The complete pattern of relationships of value conflict and compatibility among value priorities give rise to a circular structure of value systems. Competing value types emanate in opposing directions from the center; complementary types are in close proximity going around the circle. There are three methods for value assessment (Vera Martínez, 2001), namely: (1) by inferring on the observed behavior of people to determine the values to which they adhere, (2) by asking people to share their values explicitly with us, and (3) by giving people a set of stimuli such as questionnaires which they must answer. Hechter (1993) and Rokeach (1973) state that the objective evaluation of values by observation is inappropriate, because it is information difficult to categorize and to quantify, and is influenced by the observer's values. The second form of evaluation is in a way difficult for the individuals, since they are asked to respond to issues that perhaps have never been a matter of reflection for them. The difficulty for people in this case resides in the expression of their values in words they transmit to the interviewer. An intermediate position sustains that people have a series of stable values of moderate complexity that they put into practice when facing different daily life situations. In this way, both the questionnaires and the surveys turn out to be useful and easy to apply, especially among large populations. Nevertheless, these instruments are not exempt of problems. One of the main problems lies in that the predetermined formulation of elements might not necessarily be any of the person's values or that the different participants interpret differently each stimuli. The main goals for this study are: (a) to adapt and validate the PVQ (Portrait Values Questionnaire) for the assessment of human values and (b) to verify individual differences in two contexts (civil and military), as well as in gender and age. Data were taken from an Argentinian population (N = 692) in three different contexts: (a) a civil setting (n = 471), (b) among military officers (n = 97), and (c) military cadets (n = 124). The study allowed us to verify partially the value structure proposed by the author. PVQ reliability is adequate in all three contexts applied. We were also able to verify that the civil population is more oriented by Self-enhancement and Openness to change (Achievement and Hedonism) compared to military population. The latter were more oriented by values related to Conservatism (Tradition and Conformity). We found no differences related to gender and age.

Resumen en español Estudio descriptivo relacional de corte transversal, cuyo propósito fue analizar la percepción del funcionamiento familiar de los trabajadores jefes de hogar en sistemas de turnos rotativo, su pareja y un hijo adolescente. El universo estuvo constituido por el total de los trabajadores en sistemas de turno de la empresa. La muestra fue 142 familias de trabajadores que reunían las características para el estudio, 59 familias constituyeron la unidad de análisis. Para r (mas) ecolectar los datos se utilizó el instrumento "Cómo es tu familia, cómo es su familia", de Hernández A. Los ítemes con significación estadística que resultaron predictores del funcionamiento familiar fueron: Comunicación padre-madre-adolescente, y sus cuatro dimensiones, Afrontamiento de problemas global, Búsqueda de apoyo social, Esfuerzo personal, Poder-dinero y sexo, Satisfacción global, Satisfacción con la vida, y Rendimiento académico/laboral. Existieron ítemes sin significación estadística pero que pueden constituirse en predictores de riesgo por su condición de déficit. El funcionamiento familiar de las familias estudiadas es bueno aunque no óptimo. Se destaca como grupo socialmente privilegiado al compararlos con la población media de trabajadores del país, dado sus condiciones económicas, educacionales y culturales, además de un gran apoyo laboral. Los hallazgos indican que en la gran mayoría de los factores existe una tendencia a agruparse en rangos de media-baja vulnerabilidad o riesgo, que implican una baja alteración del funcionamiento familiar Resumen en inglés A descriptive relational and cross section study whose aim is to analyze the perception of the family management of householder workers in rotating shift systems, his/her spouse and a teenager son/daughter. The universe consists of the amount of workers in a plant shift system. The sample was 142 families of workers which had the characteristics for the study, being 59 families considered as analysis unit. The instrument used for data collection was the survey "Cómo es t (mas) u familia, cómo es su familia", by Hernández A. The items with statistical significance that turned out determinant in the family management were: Father-Mother-Adolescence Communication, and its four dimensions. Facing of Global problems, Searching for Social Support, Self-effort, Power-Money and Sex, Global Satisfaction. Life Satisfaction and Academic/Labor Achievement. There were items without statistical significance, but might be determinant of risks due to their deficit condition. The management in the families who were studied is good but not optimal. It stands out as a socially privilege group when compared to the standard worker groups in the country, due to the economic, educational and cultural conditions, besides a great labor support. The findings show that there is a tendency to group the ranges of medium and low vulnerability or risk in the great majority of factors, which imply a low alteration in the family management

El rol de la instrucción en la comprensión simbólica temprana de mapas/ The role of instruction in early comprehension of maps

2008-12-01

Resumen en español Se informan los resultados del estudio del desarrollo de la comprensión simbólica de mapas por parte de niños pequeños. El propósito fundamental consistió en investigar el rol de la instrucción del adulto en el desarrollo temprano de dicha competencia. Se presentan dos estudios en los cuales se realizó una tarea de búsqueda en la que los niños debían utilizar un mapa para encontrar un juguete en una habitación pequeña. En el primer estudio se comparó la ejec (mas) ución de dos grupos de niños de 30 y 36 meses, brindándoles instrucciones explícitas acerca de la relación mapa-habitación. Se pretendía conocer si dicha relación era susceptible de ser enseñada a los pequeños. Los resultados indicaron que a los 30 meses los niños no lograron el insight representacional, o sea comprender que el mapa y la habitación se hallan relacionados simbólicamente. A los 36 meses, los niños en su mayoría no resolvieron correctamente la primera subprueba, pero luego de recibir instrucción explícita, alcanzaron el insight representacional. En el segundo estudio se examinó a partir de qué edad los niños son capaces de comprender y utilizar la función simbólica de un mapa sin la instrucción del adulto. Se encontró que mientras a los 42 meses algunos niños fueron capaces de resolver la prueba, a los 46 meses la mayoría alcanzó el insight representacional. Esta investigación muestra claramente que la comprensión temprana de mapas no sólo depende de la edad; el andamiaje que proporciona el adulto, bajo la forma de instrucción, es también crucial en algunos puntos del desarrollo. Resumen en inglés Very early in life children must learn to master a wide variety of symbolic systems and objects for a full participation in the culture, like letters, numbers, and pictures. The symbolic systems, like numbers or letters are elements that do not have significance on their own, but provide information when combined in systematic ways. Symbolic objects, on their own, are objects that represent, with different degrees of iconicism or similarity, real entities and provide and (mas) transmit specific information. Symbolic objetcs, then, have a dual reality, they are physical objects and, at the same time, they are symbols of the entity they represent. This double nature of symbolic objects is very hard to comprehend by very young children. Symbolic objects can be tridimensional, like scale-models, or bidimensional, as photographs or graphs. This research is focused in the study of the development of early symbolic comprehension of a particular bidimensional symbolic object: a map; specifically we study the role of instruction in this process. Maps can be found among the symbolic objects of a given culture. Like other symbolic objects, they amplify aspects of our perception, attention and cognition; their specific role consists in representing and making comprehensible spatial information. The purpose of this research is to explore if, when and how instruction could affect young children's understanding and use of maps. Specifically, we wanted to know if it is possible to teach very young children the symbolic function of a map, and, if so, when is this possible. An important factor in children's symbolic functioning is the nature and extent of adult informational support. Although we know a great deal about the relation between adult scaffolding and the understanding and production of language and symbolic play, we still know relatively little about the influence of this factor in other symbolic domains such as external representations. So far, no study has investigated the impact of direct instruction or teaching on the detection and use of objects as symbols. In this research a novel manipulation of instruction is proposed: explicit instruction. Explicit instruction implies that the experimenter not only provides complete and detailed information about the symbol-referent relation before the task begins, but also, if necessary, during the task the experimenter corrects and directly teaches the child how to employ the map in order to find the hidden object. The two studies presented in this paper employ a search task in which children have to use a map in order to find a hidden toy in a small room. The first study compares the performance of two age group children (30 months and 36-month-olds) with explicit instructions about the map-room relation. The aim of this study is to find out if it is possible to teach little children the symbolic function of a map. The results show that while 30-month-old children are not able to recognize the map-room relation at all, the majority of 36-month-olds children achieved representational insight after failing the first search and being explicitly taught how to use the map. The second study examines at what age children are capable of recognizing and using the symbolic function of a map without adult's instruction. It was found that while at 42 months old some children are able to solve the task with no instructions at all, at 46 months the majority of children achieve representational insight. This research clearly shows that the early comprehension of maps is not solely dependent of age and maturation, the scaffolding that adult instruction provides is also crucial at some points of development.

Resumen en español Se analiza la situación que guarda la educación ambiental en el nivel superior, mediante el estudio de caso de la Universidad Autónoma de Campeche. Se realizó una investigación de carácter exploratoria que combina métodos cuantitativos y cualitativos para diagnosticar el grado de cultura ambiental de los estudiantes de la Universidad Autónoma de Campeche y el tipo de educación ambiental que reciben. Los resultados indican que los estudiantes poseen un nivel de cu (mas) ltura ambiental bajo y que carecen de los conocimientos y de las habilidades necesarias para realizar cambios ambientalmente favorables en sus estilos de vida. Se resalta que el contexto institucional opera como un factor que inhibe la educación ambiental debido a que la formación ambiental no es considerada prioritaria y por lo tanto no existen los espacios, la infraestructura y los apoyos necesarios para su estudio, enseñanza y promoción. Se requiere un cambio radical en la formación de los maestros para superar el tipo de enseñanza que se practica, centrada en proporcionar información sin una compresión profunda de la complejidad y la interdependencia entre los sistemas naturales y socioeconómicos. Resumen en inglés This study examined the state of environmental teaching at the higher education level through a case study in the Autonomous University of Campeche. An exploratory study was carried out, combining quantitative and qualitative methods, in order to diagnose the degree of environmental literacy in the students of the Autonomous University of Campeche and the type of environmental education they receive. Results indicate that the students have a low level of environmental lit (mas) eracy and that they lack the knowledge and necessary skills to carry out favourable environmental changes in their life styles. It is notable that the institutional context operates as the factor that inhibits environmental education, as this is not considered essential and therefore there are no spaces, infrastructure and support, that are necessary for its study, teaching and promotion. A radical change in the formation of the teachers is required to improve the type of teaching that is practiced, as it is at present centered in providing information without a deep comprehension of the complexity and interdependence that exist between the natural and socioeconomic systems.

Echinococcosis quística: epidemiología y control en América del Sur/ CYSTIC ECHINOCOCCOSIS: EPIDEMIOLOGY AND CONTROL IN SOUTH AMERICA

Resumen en inglés Hydatidosis is a zoonosis produced by a parasite, Echinococcus granulosus, of high prevalence in Argentina, Uruguay, Chile, Peru and the south of Brazil, producing high losses for cattle raising and for health systems. Man acts as a host for the metacestode and is infected when ingesting fertile eggs adhering to the anus or hair of parasitized dogs or by ingestion of vegetables or water polluted with canine feces. Major epidemiological risk factors are: to slaughter sheep (mas) in the household, to cohabit with a great number of dogs during the first years of life, to have a history of hydatidosis cases in the family nucleus, to use non-potable water and to be in contact with parasitized dogs. It has been estimated that over 2000 new human cases are reported every year in the region, with rates of incidence ranging from 41 per 100,000 in the Patagonian region in southern Argentina, 80 per 100,000 in the XI Region of Chile, up to 100 x 100,000 in the Flores Department of Uruguay. Successful programs based on systematic canine deparasitation with praziquantel have been developed in Uruguay, Chile and Argentina, with diverse organization models. Traditionally, cystic echinococcosis has been regarded as a disease requiring surgical resolution. However, during the last years alternative methods have been developed including chemotherapeutic treatment with albendazol and minimally invasive surgical procedures such as echo-assisted puncture (PAIR). The Ministers of Agriculture and Health attending the XII RIMSA approved Resolution RIMSA12.R7 requesting the Pan American Health Organization (PAHO) to strengthen cooperative actions and coordination among countries and their institutions in matters related to hydatidosis control and prevention. In implementing this directive, the PAHO through the Program of Veterinary Public Health and its specialized center, the Pan American Center of Foot-and-Mouth Disease (PANAFTOSA), initiated actions to consolidate efforts carried out throughout the continent for hydatidosis control, establishing the mechanisms of collaboration among countries that have been developing control actions and drawing up a strategy of joint action aimed to strengthen and to support the actions \\ overall thrust

Resumen en inglés This report explains how and why to evaluate the technology employed in health care. This technology includes not only medicines, instruments, equipment, and procedures used directly on patients, but also the organizational models and support systems that make health care possible. During the various stages of a technology’s life cycle, an assessment is made of several different characteristics, such as safety and effectiveness, clinical utility, economic impact, and (mas) effect on the organiztion and provision of services. Originally, the ways of assessing and testing technical methods were only of interest to manufacturers and service providers. Today, however, the interested parties include legislators, government officials, health administrators, researchers, industrial managers, and, certainly, patients and their families. Therefore, health technology assessment is a highly important activity and its promotion is an element of PAHO’s technical cooperation with the Member States.
