Este documento estudia cómo la migración afecta las decisiones de las mujeres rurales jóvenes con respecto al estado civil, a tener hijos y a usar métodos anticonceptivos. Los resultados muestran que efectivamente las decisiones de las mujeres jóvenes migrantes difieren de las de aquellas que permanecen en zonas rurales. En particular, las mujeres migrantes se inclinan más por casarse o convivir con su pareja que a permanecer solteras, y prefieren la unión libre sobre el matrimonio. Además, usan con más frecuencia métodos anticonceptivos modernos y, si bien tienen menor probabilidad de tener hijos, en promedio, tienen más hijos que las mujeres rurales que no migran. También se investiga si al migrar, las mujeres mejoran su posición de negociación en el hogar. En este ejercicio, diferenciamos a las mujeres entre aquellas que se casaron antes y después de migrar. Las mujeres...

            The aim of this study was to determine the behaviour and management practices related to the welfare of the animals destined for slaughter in an abattoir in the city of Sogamoso, Boyacá, Colombia. Behavioural and management indicators were evaluated before, during and after desensitization in 100 cattle aged 1 to 5 years. The evaluation parameters were classified as excellent, acceptable, not acceptable and problem, according to a system proposed by the American Meat Institute. It was found that 11% of the animals suffered falls and 17% slipped, 23% vocalized and that in 61% of the animals the electric prod or another instrument was used for their mobilization, these facts being considered as problem from a wellness viewpoint. In the desensitization process, 93% correct stunning was obtained with a single shot and stunni...

             Objective: To determine the surface roughness and color stability of a nanohybrid resin subjected to different salivary pH at different times. Materials and methods: experimental, comparative, in vitro study, in which 45 discs of EA2 nanohybrid resin (OPALLIS FGM) of 10 mm in diameter and 1 mm in thickness. They were randomly distributed in three groups (n = 15), each of the resin discs was subjected to an evaluation of its roughness by means of a digital roughness meter (TESTER SRT-6200) and color by colorimeter (Tooth Color Comparator). The discs according to their group were immersed in 18ml of artificial saliva modified with citric acid until obtaining saliva of pH 5, 6 and 7 respectively and placed in specific reservoirs maintained at 37 ° C, according to the specifications of the ANSI / ADA n0 standard. 66, after 168 and 504 hours of storage, a second and thir...

"Este documento caracteriza las mujeres rurales jóvenes colombianas en cuatro dimensiones fundamentales: capital humano, contextos de vida, estrategias de vida y vínculos con el Estado. Las tendencias encontradas para las mujeres rurales jóvenes se compararon con las de otros grupos pertinentes: hombres rurales jóvenes (para estudiar la brecha de género), con mujeres urbanas jóvenes (brecha de lugar de residencia), con mujeres rurales mayores de 35 años (brecha generacional), y separando a las mujeres rurales jóvenes y sus familias entre las pobres y las no pobres (brecha de pobreza). Los resultados muestran que las brechas de género y de lugar de residencia (urbano-rurales) son las más significativas para casi todas las variables analizadas. La alta vulnerabilidad de las mujeres rurales jóvenes y la creación de un estereotipo urbano parecieran crear un esquema de incentivos ...
