Abstract:

The purpose of this qualitative case study, carried out in two phases, is to systematize the learning experiences and expectations of older adults and their families as they face approaching retirement, in Guadalajara, Mexico, 2012. The strategy implemented was an educational preparation for retirement. Six adults had already retired, two were soon to be retired and eight family members were chosen for this study. Data were collected using semi-structured interviews and a SQA-E format. The educational strategy was an interactive conference. A phenomenological analysis was made of the experiences recorded. The naturalistic criterial evaluation of learning experiences and expectations was applied before and after the educational intervention. Through this intervention, participants were made conscious of their problems, expressed the desire to improve certain aspects of their lives and continued educational preparation.

Abstract: the use of honey in traditional and complementary/alternative medicine needs evidence to explain the bioactive properties of this product from the hive. the analytical techniques of the codex alimentarius commission for safety and trading quality control purposes, are not sufficient to differentiate this apparently homogeneus but complex bee product. in this work, the antioxidant capacity of apis, melipona and trigona honey from venezuela, was measured within three oxidative systems, to test the effectiveness of honey at scavenging superoxide anion (o2●-) formation, hydroxyl radical (oh●) formation and benzoate degradation (aoa). all the diluted genuine honey samples showed higher antioxidant capacity indicators than those of artificial honey and the mild antioxidant control lipoic acid. however, melatonin and quercetin, the potent antioxidant controls used here, were better scavengers than genuine honeys in the oh● and the aoa assays, which are hydroxyl radical generating systems. this is the first time that aoa is used to determine the honey antioxidant capacity. besides its use to measure bioactive properties, the antioxidant capacity indicators used here could also become a test to control adulterated honey. the entomological origin was not related to the antioxidant properties of honey

Abstract: El uso de la miel en medicina tradicional y complementaria/alternativa necesita evidencias para explicar las características bioactivas de este producto de la colmena. Las técnicas analíticas sugeridas por la Comisión del Codex Alimentarius para la inocuidad y los propósitos del control de calidad y de comercialización, no son suficientes para diferenciar este complejo producto de las abejas, aparentemente homogéneo. En este trabajo se midió la capacidad antioxidante de la miel producida por los géneros Apis, Melipona y Trigona de Venezuela, utilizando tres sistemas oxidativos, para probar la eficacia de la miel en la inhibición del anión del superóxido (O2●-), la formación del radical hidroxilo (OH●) y la degradación del benzoato (AOA). Todas las muestras de miel genuina diluida presentaron indicadores antioxidantes más altos que los de la miel artificial y del ácido lipoico utilizado como control antioxidante suave. Sin embargo, la melatonina y la quercetina, los controles antioxidantes potentes usados aquí, fueron mejores limpiadores que las mieles genuinas en los análisis de OH● y del AOA, que son sistemas generadores de radicales hidroxilo. ésta es la primera vez que se utiliza AOA para determinar la capacidad antioxidante de la miel. Además de su uso para medir características bioactivas, los indicadores de capacidad antioxidante aquí usados podrían proponerse en como análisis para controlar la miel adulterada. El origen entomológico no se relacionó con las características antioxidantes de la miel The use of honey in traditional and complementary/alternative medicine needs evidence to explain the bioactive properties of this product from the hive.

Abstract: Resumen Frente al propósito de disminución del déficit habitacional del país, la figura del arrendamiento cobra importancia como herramienta que, además de contribuir de manera directa a su disminu-ción, puede llegar a constituir una opción de inversión rentable. Adicionalmente, en un contexto caracterizado por limitaciones fiscales del estado, precariedades de las viviendas existentes, difi-cultades en el acceso a créditos hipotecarios e ineficiencia en la gestión urbana, entre otras, el arrendamiento se convierte en una alternativa de solución habitacional, en el corto plazo, para los hogares más pobres. Por lo anterior, la investigación adelantada responde a la necesidad de caracterizar el mercado de arrendamiento urbano, enfocado en el segmento de población más pobre. Buscando identificar las posibilidades de articular estos mercados en un marco formal que posibilite su interrelación con instrumentos financieros que apalanquen la oferta de vivienda en arriendo, para los estratos bajos de la población. Abstract Given the aim of decreasing Colombia’s housing shortage, the possibility of renting is important as a tool that, in addition to contributing directly to the reduction of housing shortage, can be a profitable investment option. Additionally, in a context of fiscal constraints at national level, poor conditions of existing homes, difficult access to mortgages and inefficiency in public administration at municipality level, among other aspects, renting is an alternative short term solution for the poorest. The present research was carried out in order to respond to the need for a characterization of the urban rental market, focusing on the poorest segment. It seeks to identify the possibilities of fitting these markets in a legal framework that enables their interaction with financial instruments, so that the supply of rental housing for the lower strata of the population can be stimulated.

Abstract: in 2003 the number of hectares with tomato crops in colombia, was over 16.000. with the increase of the cultivated area, the number of plagues such as the white fly of the greenhouses, trialeurodes vaporariorum, also increased. the most common methods for the control of the white fly are the use of insecticides, cultural practices like defoliation, yellow sticky traps and, the use of natural enemies like encarsia formosa. although the efficiency of this parasitoid has been demonstrated, the determination of the maximum distance in which the parasitism reaches effective levels, was needed. in order to reach this objective, e. formosa was released based on its functional response, and according to the distribution and density of the plague in each sampling point. in those areas were higher densities of white fly were found, more parasitoids were released. as a result the percentage of parasitism was higher compared with the rest of the area. a radio of action between 8 to 10 m was found for this parasitoid, with a maximum parasitism of 47.27%.
