Definición de perfiles basados en actitudes hacia los programas de apoyo público de los microempresarios rurales de la comuna de Cauquenes, Región del Maule
(Universidad de Chile, 2014)
La presente investigación tiene como propósito identificar las actitudes de los beneficiarios de los programas de apoyo público dirigidas a microempresarios rurales en la comuna de Cauquenes, Región del Maule, Chile. Para ello, se llevó a cabo una...
This research aims to identify the attitudes of beneficiaries of public support programs, aimed at rural micro entrepreneurs in the commune of Cauquenes, Maule Region, Chile. For this purpose, a survey was conducted of 126 of these micro entrepreneurs, which participate in a support program coordinated by the Municipality of Cauquenes together with the Institute of Agricultural Development (INDAP). The survey focused on the following topics: a) identification of the producer and their homes, b) characterization of the productive system, c) farm and non-farm income, d) participation in social networks, e) sustainable handling of productive resources, f ) innovation activities, g) participation in other public programs, and h) attitudes toward public programs. The data emanating from the above, was applied a descriptive analysis in first place, to obtain a characterization of respondents. After it is review in greater depth responses to the statements contained in paragraph h), later to apply a non-hierarchical cluster analysis in order to determine profiles. The above identify the existence of two groups of entrepreneurs, according to their attitudes towards public support programs, identified like "traditional" (30.15%) and "innovative-informed" (69.84%) which are principally differentiated by their attitudes about partnerships, training targets, requirements for access to public programs, the support provided by the public sector, among others. Finally, a number of recommendations were established based on the results obtained, for example, the need to make the information of public programs more easy to the micro entrepreneurs, associative, collaboration between different government organizations, use of ICT, among others....

Efectos de la administración de vitaminas antioxidantes en la gametogénesis y el estatus redox del semen en carneros expuestos a la altura
(Universidad de Chile, 2019)
Introducción: La producción ovina es el principal recurso de familias que habitan a gran altura. Sin embargo, presenta una eficiencia reproductiva pobre en relación con lo registrado a nivel del mar. La hipoxia hipobárica propia de ambientes a gran...
Introduction: The sheep production is the main resource of families living at high altitude. However, has a poor reproductive efficiency in relation to that recorded at sea level. Hypobaric hypoxia at high altitude environments produces oxidative stress, which leads to detrimental effects on the reproductive system. Low fertility rates, low intrauterine development and low birth weights are some of the damaging effects of exposure to high altitude. Therapy with antioxidant in ewes maintained at high altitude has been shown to reduce oxidative damage caused by hypoxia and increase reproductive capacity. For these reasons, supplementation with antioxidant vitamins C and E was evaluated in its capacity to attenuate the oxidative deleterious effects on reproductive function in rams exposed to high altitude for short or long periods. Materials and Methods: Three groups of rams were evaluated, rams born and kept at sea level (BB, n = 20); rams born at sea level and exposed to high altitude (BA; n = 50); born and kept at high altitude (AA; n = 50). Half of the animals in each group were daily supplemented with 600 mg of vitamin C and 450 IU of vitamin E, orally, for 240 days. The cell populations present in the seminiferous epithelium, the sperm morphology in the ejaculate and the antioxidant status of seminal plasma were analyzed. Results: Oral supplementation with vitamins C and E prevented and / or softened the reduction of the spermatogonial population, the reduction of the height of the seminiferous epithelium and the tubular diameter, the decrease of the total antioxidant capacity and reduced the degree of spermatogenic arrest at day 30 in rams not adapted to high altitude However, it did not have effects on sperm morphology and enzymes present in the seminal plasma of rams exposed at high altitude for a short and long periods. Conclusion: Supplementation with antioxidant vitamins favors the spermatogenesis and the total antioxidant capacity of the seminal plasma of rams not adapted to high altitude in the short term....
