Abstract: La elodea (Egeria densa), un problema para lagos y lagunas en Colombia, puede ser materia prima para la producción de abonos orgánicos de bajo costo y de buena calidad. Para emplearla en la obtención de abonos orgánicos, se elaboraron fertilizantes a partir de seis formulaciones, así: 1) Elodea 50% cal dolomítica 20% levadura 5% melaza 5% gallinaza 20%. 2) Elodea 60% cal dolomítica10% levadura 3% melaza 8% gallinaza 19%. 3) Elodea 70% cal dolomítica 15% levadura 2% melaza 3% gallinaza 10%. 4) Formulación 1 + lombricompuesto; 5) Formulación 2 + lombricompuesto y 6) Formulación 3 + lombricompuesto. Para cada uno de los abonos, se determinó el contenido total de N, P2O5, K2O, MgO, CaO, carbón oxidable total, coliformes y relación C:N. Bajo condiciones de invernadero, se evaluó el efecto de los abonos en un Andisol sobre el cultivo de lechuga e igualmente, se monitoreó la temperatura y el pH a través del periodo de producción de los abonos. En general, el contenido de los elementos analizados y la relación C:N cumplen los requisitos para estos abonos. Hubo efecto significativo del contenido entre formulaciones y en el bioensayo para rendimiento entre formulaciones y dosis, siendo la formulación tres la de más alto rendimiento. De igual manera hubo efecto significativo de fuentes y de dosis en el contenido de N-P-K en la lechuga. El pH de los seis abonos fue de 7,00 a 7,30, considerado apropiado. Se demostró la factibilidad de producción de abonos orgánicos de buena calidad a partir de elodea.

Abstract: the common 'popping' bean is characterised by its cotyledons' ability to expand on being subjected to heat, making this type of common bean an innovative genetic resource, having interesting prospects as snack food or candy for both local and export markets. given its origin and selection in the south-american andes, this bean could adapt itself to high andean areas in the colombian ordillera and become a product diversifying itself and providing commercial prospects for the region's local inhabitants. this work evaluated the bean's agronomic and chemical characteristics, growth and functional opping properties of 29 popping bean accessions from peru and bolivia by correlating and selecting the variables having the greatest affect on characterisation. the information so obtained allowed the accessions to be grouped according to the aforementioned characteristics into two conglomerates. the variables providing the most information regarding the accessions were precocity and yield, followed by nutritional quality and percentage of expansion. shell colour, predominant limb colour, pod colour and seed form featured amongst the nominal variables. accessions selected for yield presented for plant were g12575, g12586, g7245 and g24886. accessions having promising expansion percentage were g23729, g12570, g12623, g23715, g23736, g23742, g23767b, g12605, g23693 and 23695.

Revista CS , 2010,
Abstract: Un espacio educativo significativo es un ambiente de aprendizaje que promueve y fortalece el desarrollo de competencias sociales y cognitivas en los ni os. Este artículo ofrece elementos conceptuales y metodológicos de la psicología educativa que facilitan el dise o de espacios educativos significativos para el desarrollo de competencias infantiles dentro y fuera del aula. Por una parte, se brinda una definición de ambiente de aprendizaje que permite comprenderlo como un espacio dinámico y complejo de construcción de conocimiento. De otra parte, teniendo en cuenta algunas consideraciones sobre la concepción de desarrollo infantil, se establecen cinco criterios para caracterizar los ambientes de aprendizaje como espacios educativos significativos: situaciones estructuradas, intensivas, extensivas, generativas y ricas en formas de interacción. Cada uno de los criterios se ilustra con ambientes de aprendizaje dise ados por agentes educativos de Colombia, basados en el uso de prácticas culturales de sus comunidades de origen. Las prácticas culturales resultaron ser pertinentes para el desarrollo de las competencias de sus ni os. A meaningful educational space is a learning environment that promotes and strengthens the development of social and cognitive competencies in children. This article offers conceptual and methodological elements from Educational Psychology that facilitates the design of significant educational spaces for the development of child competencies, both in and out of school. On the one hand, the learning environment is defined as a dynamic and complex space of construction of knowledge. On the other it takes into account some considerations about child development which help set five criteria to characterize learning environments as meaningful educational spaces: They are structured, intensive, extensive, generative and interactive situations. Each of these criteria is illustrated through learning environments designed by educators in Colombia, based on the use of cultural practices inherent their communities of origin. Cultural practices were found to be relevant to the development of their children’s competencies.
Catolicismo y ciencia moderna

Ingeniería e Investigación , 1985,
Abstract: En un trabajo anterior fue posible mostrar lo aleatorio de las bases científicas del materialismo. Ante ciertas inquietudes resulta indispensable confrontar la actitud de la iglesia católica frente al mismo tema; las presentes líneas aspiran a ser tan solo un esbozo al respecto.
Contrarréplica a “Apostillas sobre Catolicismo y ciencia moderna”
Corsi Otálora Luis
Ingeniería e Investigación , 1990,
Abstract: En momentos en los cuales parece casi extinguido el espíritu universitario de análisis acerca de los grandes problemas conceptuales, es de celebrar que los profesores Luz Amanda Salazar Hurtado y Fabio Barrera TélIez, se hayan tomado la molestia de comentar y criticar el trabajo Catolicismo y Ciencia moderna. Permiten así proponer debates que superen, por una parte, los pobres marcos de una tecnocracia pendiente de la rentabilidad de sus estudios; por otra, capaces de aclarar un poco el panorama de un cientifismo saturado de monta as de saber inasimilado, a causa del exceso respeto a tratados de autores con nombre resonante.
La relación existente entre el conflicto trabajo-familia y el estrés individual en dos organizaciones colombianas The existing relation between work - family conflicts and individual stress in two Colombian organizations
Guillermo Otálora Montenegro
Cuadernos de Administración , 2007,
Abstract: El propósito de este artículo es explicar cómo los conflictos que surgen en la relación trabajo-familia se relacionan con el estrés individual en dos organizaciones colombianas, específicamente dos cajas de compensación familiar situadas en Bogotá. Las siguientes hipótesis constituyen el objeto del trabajo: (a) la carga laboral y las responsabilidades familiares están positivamente relacionadas con el conflicto trabajo-familia y (b) el conflicto trabajo-familia está positivamente relacionado con el estrés individual. El estudio de campo realizado en las dos organizaciones mencionadas especializadas en proveer a los empleados servicios básicos como salud, vivienda, recreación y educación, entre otros, da evidencia que valida las hipótesis planteadas. Se discuten algunas implicaciones prácticas y teóricas, al igual que se propone ahondar en la investigación que permita avanzar en el conocimiento de los mecanismos a través de los cuales el conflicto trabajo-familia conduce al estrés individual.

Park of the Affects: Communication, to Be Together and Recognition in the Intersubjectives Relations of Young People in Their Experience of Inhabit a Park  [PDF]
Mónica Marión Cata?o Otálora
Advances in Journalism and Communication (AJC) , 2017, DOI: 10.4236/ajc.2017.52004
Abstract: This article presents a research done with young people in the city of Cali-Colombia and investigates their ways of being together, their forms of recognition and their intersubjectives relationships that underlie the experience of inhabiting a certain park. The affective turn of cultural studies and Spinoza’s affective theory are those that illuminate the work that corresponds to a comprehensive study with an ethnographic approach and takes up the narratives of young people to describe the topophilia or room experience. The main results of the research point to the affective communities as the new forms of grouping of young people, the language of affection, the mixing of expressive languages with those that weave their communicative ties and perform their practices of resistance in defense of place, which is not only a place to be but is constituted instead of being.
