EFECTO DEL GRADIENTE ALTITUDINAL SOBRE ASPECTOS AUTOECOLóGICOS DE ESPELETIA PYCNOPHYLLA ssp. ANGELENSIS CUATREC. (ASTERACEAE) EN EL PáRAMO EL INFIERNILLO (NARI?O-COLOMBIA)

Abstract: some autoecological features of espeletia pycnophylla ssp. angelensis cuatrec. such as its demographic structure, population density, spatial pattern of dispersion, production of reproductive structures, adult morphometry and survivorship, were studied in an altitudinal gradient on a dry paramo of nari?o (colombia). hypothesis proposed by other authors about a linear effect caused by the elevation on these variables were completely rejected. the elevation induces an ecoclinal effect on population density, and this density correlates negatively with both production of reproductive structures and adult sizes. these results elucidate an unequivocal effect of density-dependence phenomena on population fitness. the intermediate zone of the altitudinal gradient exhibits a high population density, but on the other hand show reduced corporal adult sizes, minimal production of reproductive structures and the probability of juveniles reaching advanced ages is low. evidently, this intermediate elevation can have favorable ecological conditions for the seedling establishment, wich increments population densities at long term. we propose that other author's generalizations about the influence of elevation on the autoecology of these plants are limited, because the particular life and disturbance stories of paramos and the spatial, ecological and genetic isolating are explicative factors impossible to take away from the context. the demographic structure of the population fitted the logarithmic model, revealing its early regeneration state from the last fire event on 2003 and the similarity of the survivorship curves among every elevation, probed a high demographic stability.

Abstract: Se estudió el efecto de la elevación sobre algunos aspectos autoecológicos de la especie Espeletia pycnophylla ssp. angelensis Cuatrec. (Asteraceae), tales como su estructura demográfica, densidad poblacional, patrón de distribución espacial, producción de estructuras reproductivas, morfometría de adultos y supervivencia, en un páramo seco del departamento de Nari o (Colombia). Las hipótesis propuestas por otros autores acerca del efecto lineal que la elevación produce sobre estas variables, fueron completamente rechazadas. La elevación induce un efecto coenoclínico sobre la densidad poblacional y ésta a su vez, se correlaciona negativamente con la producción de estructuras reproductivas y el tama o de los adultos, evidenciándose un efecto inequívoco del fenómeno de la densodependencia sobre el potencial biótico de la población. En la zona intermedia del gradiente, la densidad poblacional es máxima, pero los tama os corporales son reducidos, la producción de estructuras reproductivas es mínima y la probabilidad de que un juvenil alcance edades avanzadas es baja. Evidentemente, esta elevación intermedia estaría presentando condiciones ecológicas favorables para el establecimiento y supervivencia de plántulas, lo que a largo plazo conlleva a un aumento de la densidad poblacional. Se propone que las generalizaciones de otros autores acerca de la influencia de la elevación sobre la autoecología de estas plantas son inverosímiles y limitadas, ya que la historia particular de vida y disturbio del páramo y los aislamientos espaciales, ecológicos y genéticos, son factores explicativos que no pueden aislarse del contexto. Paralelamente, la población se ajustó al modelo demográfico logarítmico, revelando su temprano estado de regeneración frente a la última quema ocurrida en el 2003, y la similitud de las curvas de supervivencia entre todas las elevaciones, probó una alta estabilidad demográfica.

Cuadernos de Administración (Universidad del Valle) , 2009,
Abstract: the organizational climate is now a key factor in business development, and thorough study, diagnosis and improvement directly affects the so-called spirit of the organization. it is for this reason that this paper makes a conceptual approach, since different authors, which helps to highlight the importance of climate in organizational changes, and outlines the various tools that can be used for measurement and diagnosis and consider many variables that revolve around the organization?s values, beliefs, customs and business practices, and clarifying the causes of satisfaction and dissatisfaction at work, and thus the incidence of these in the organizational changes.
Los macro-procesos: un nuevo enfoque en el estudio de la Gestión Humana
García Solarte,Mónica;
Pensamiento & Gestión , 2009,
Abstract: human resources management involves processes and strategic activities that serve as backup and support for the organizations management through the establishment of policies, plans and programs to select, train, reward, develop and motivate the organizations' staff with the purpose to potentiate the human factor as a key element of the competitive advantage of the organization and the creation of value in it. the classification of the processes according to their objective or purpose in macro-processes gives a new approach to human management by identifying and describing five of them in a logical sequence, but they can also occur simultaneously, demonstrating that the processes can not be viewed in isolation and that this union is critical in the pursuit of organizational development and competitiveness.

Abstract: La gestión humana involucra procesos y actividades estratégicas que sirven como apoyo y soporte para la Dirección de la Organización. En este artículo de investigación se muestra cómo mediante el establecimiento de políticas, planes y programas se puede seleccionar, formar, retribuir, desarrollar y motivar el personal de la organización con el fin de potencializar el ser humano como factor fundamental de la ventaja competitiva de la organización y la generación de valor en su interior. La clasificación de los procesos de acuerdo con su objetivo o fin determinado en macroproce-sos, le dan un nuevo enfoque a la gestión humana al identificar y describir cinco de ellos en un orden lógico secuencial, aunque también pueden presentarse de manera simultánea, lo cual demuestra que los procesos no pueden verse de manera aislada y que esta agrupación es fundamental en la búsqueda del desarrollo y la competitividad organizacional.

Cuadernos de Administración (Universidad del Valle) , 2009,
Abstract: El clima organizacional es hoy un factor clave en el desarrollo empresarial, y su estudio en profundidad, diagnóstico y mejoramiento incide de manera directa en el denominado espíritu de la organización. Por lo anterior, en el presente documento se realiza una aproximación conceptual desde diferentes autores, que ayuda a evidenciar la importancia del clima en los cambios organizacionales. De igual forma, se exponen las diferentes herramientas que se pueden emplear para su medición y diagnóstico y que consideran numerosas variables que giran en torno a los valores de la organización, las creencias, costumbres y prácticas empresariales, para esclarecer las causas de la satisfacción e insatisfacción en el trabajo, y su incidencia en los cambios organizacionales.

Journal of Epilepsy and Clinical Neurophysiology , 2009, DOI: 10.1590/S1676-26492009000400009
Abstract: rationale: benign focal seizures of adolescence (bfsa) described by loiseau et al in 1972, is considered a rare entity, but maybe underdiagnosed. although mild neuropsychological deficits have been reported in patients with benign epilepsies of childhood, these evaluations have not so far been described in bfsa. the aim of this study is to evaluate neuropsychological functions in bfsa with new onset seizures (<12 months). methods: eight patients with bfsa (according to loiseau et al, 1972, focal or secondarily tonic clonic generalized seizures between the ages of 10-18 yrs., normal neurologic examination, normal eeg or with mild focal abnormalities) initiated in the last 12 months were studied between july 2008 to may 2009. they were referred from the pediatric emergency section of the hospital universitário of the university of sao paulo, a secondary care regionalized facility located in a district of middle-low income in sao paulo city, brazil. the study was approved by the ethics committee of the institution. all patients performed neurological, eeg, brain ct and neuropsychological evaluation which consisted of raven's special progressive matrices - general and special scale (according to different ages), wechsler children intelligence scale-wisc iii with acid profile, trail making test a/b, stroop test, bender visuo-motor test, rey complex figure, rey auditory verbal learning test-ravlt, boston naming test, fluency verbal for phonological and also conceptual patterns - fas/animals and hooper visual organization test. for academic achievement, we used a brazilian test for named "teste do desempenho escolar", which evaluates abilities to read, write and calculate according to school grade. results: there were 2 boys and 6 girls, with ages ranging from 10 yrs. 9 m to 14 yrs. 3 m. most (7/8) of the patients presented one to two seizures and only three of them received antiepileptic drugs (aeds). six had mild eeg focal abnormalities and all had normal brain ct. all w

Girón-Vargas,Sandra L.; Mateus-Solarte,Julio C.; Cabrera-Arana,Gustavo A.;
Revista de Salud Pública , 2009, DOI: 10.1590/S0124-00642009000300008
Abstract: objective estimating the difference between direct and indirect family costs arising from women who continue exclusive breastfeeding and those who abandon it during the first postpartum month. methods a cost analysis was carried out on primiparous women from cali, colombia; they were recruited during their immediate puerpery and follow-up during the first 30 postpartum days. non-parametric bootstrap techniques were used for estimating average costs and differences for 0-8, 9-30 and 0-30 postpartum days regarding women who abandoned exclusive breastfeeding and those who did not. results women who abandoned exclusive breastfeeding assumed higher costs related to baby feeding while those who continued exclusive breastfeeding had higher food costs for the mother and in contracting domestic support. conclusion the savings which a woman and her family can make due to continuing with exclusive breastfeeding become negated by the mother's food-related costs. interventions should be designed which are orientated towards prolonging exclusive breastfeeding and modifying beliefs about nutrition which contribute towards generating economic consequences for families.

Anna Flavia de Souza Silva, Sandra Helena da Cruz
Natural Science (NS) , 2016, DOI: 10.4236/ns.2016.83019
Abstract: Brazil is the largest producer of sugarcane and its derivatives in the world, and one of the largest consumers of sugarcane derivatives. Sugar places a position of great prominence in Brazilian feed, either by direct consumption or as a component of industrialized products, from increasing consumption in the country. Sugar samples taken from local market were analyzed as the quality of table sugar consumed in the state of Sao Paulo (Brazil). The analysis of the parameters and basic attributes of characterization of sugar was according to the methodology developed by ICUMSA (2005; 2011) and ICUMSA modified by Copersucar (2002). Samples of sugar from this region showed that medium-low quality. It can be observed in fundamental aspects such as purity and insoluble residues, which were below the standard. In addition, it should be noted the difficulty of obtaining information about the limit values for each attribute, by virtue of Legislation not be assertive to the product and, also, the scientific studies have not been unified to present the specifics for each type of sugar.
