Ambos fenómenos han sido, y continúan siendo, de sumo interés para quienes estudian nuestro dialecto. Un importante número de trabajos revela, largamente, que el uso de dichas variables y sus respectivas variantes, está condicionado por una serie de factores lingüísticos y extralingüísticos (sociales). Esta abundante literatura, sin embargo, se centra principalmente en hablantes adultos y adultos-jóvenes, dejando el estudio de la adquisición y desarrollo del uso de estas variables sociolingüísticas en el habla de niños/as chilenos como un terreno que invita fuertemente a su exploración. La investigación tiene como objetivo general conocer el proceso de adquisición y desarrollo de los patrones de uso de la variación del grupo consonántico /tɾ/ y el fonema /t∫/, en el habla de niños y niñas chilenos y sus cuidadores. Los datos de este estudio serán obtenidos a partir de actividades de interacción natural/espontánea diádica entre niño/a y tutor/a.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Moreover, in real world situations, it is important to bridge the gap between the theoretical insights developed through mechanism design and the implementability issues stressed in the market design literature. Real world situations might be complex for di↵erent reasons, and in this proposal I plan to study two issues which up to now have not been fully analyzed in this theoretical/applied interface. The first is regulation in the presence of vertical structures, an issue which is very common in industrial organization, but it has received surprisingly little attention in the mechanism design literature. The second is the design of new markets for natural resources, where property rights are crucial to their e�cient use, but dynamic issues make standard simple solutions very di�cult to implement and they usually perform poorly. Curbing the monopoly power of firms is a fundamental issue for regulators where the cost structure makes a monopoly unavoidable in the first place. In particular, the study of simple mechanisms that help with this goal becomes relevant. Firms are better informed about its production cost or the demand that they faced. This information gives them infor- mational rents that the regulators attempt to control to increase social welfare. While this is a well-studied problem by economists, it still generates challenges due to the complexity of real world situations. The granting of a monopoly right and the establishment of certain rules (like a quantity to produce or a maximum price to be set) is not the end of the story. Subsequently, the regulated firm will deal with downstream firms, which in turn might have significant market power in its dealings with consumers and even providers. In the first project, I study how an agent designs a mechanism to allocate resources that afterwards turns the chosen firm downstream into a mechanism designer on its on. Applications include infrastructure regulation: for example airports that in turn chose how to deal with airlines, which use their market power to extract rent from consumers. Creating markets under the “tragedy of the commons” has a long tradition in economics, dating back to Pigou (1920) . The basic intuition is simple: prices would provide agents with the right scarcity signals, leading to an e�cient resource allocation. However, dynamic issues and the uncertainty about the real value of di↵erent uses for the resource introduce significant challenges. On the second project, I study e�cient mechanisms in a dynamic framework where the value of the asset is known only by experimentation of investors. A general objective of this project is to study the conditions for which simple mechanism can be e�cient on one hand, and furthermore they increase the social welfare.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Adverse intrauterine conditions increase the risk of developing NCDs during the life course, a phenomenon known as Developmental Origins of Health and Disease (DOHaD). The most frequent and clinically relevant adverse condition during fetal life is intrauterine hypoxia (IH), which is associated with a high perinatal morbi-mortality. The molecular mechanisms that could be involve in IH causes and consequences are an important aspect in most of the pregnancies at high altitudes (> 2500m), and in 3-4% of the pregnancies with utero-placental complications at lowlands. Nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) are endogenous gasotransmitters with vasodilator properties that can regulate cardiovascular functions. These gasotransmitters may be affected by intrauterine chronic hypoxia- induced oxidative stress, eliciting vascular programming and deriving in cardiovascular dysfunction along life course. Although these gasotransmitters have shown to determine endothelial, smooth muscle and cardiac function, the role of them in the fetal programming CV dysfunction due to developmental hypoxia and their relationship with oxidative stress is still unknown. Our hypothesis is that the intrauterine development in chronic hypoxia programms the gasotransmitters pathways (NO, CO and H2S) in the heart and blood vessels through oxidative stress, which impacts in the short, medium and long term cardiovascular function. Therefore, an oral treatment with antenatal melatonin will prevent the hypoxic-induced cardiovascular impairment. In this proposal, we aim to study, in a well-characterized guinea pig model, the origins and outcomes of cardiovascular dysfunction resulting from IH, by characterizing the functional, structural and molecular aspects of vasoactive mechanisms dependent on endogenous gasotransmitters, in the heart and blood vessels. Moreover, as fetal growth restriction and cardiovascular programming are related with hypoxia induced-oxidative stress, we will implement an antenatal treatment with melatonin, a proved antioxidant, to test the prevention of IH-induced cardiovascular risks in the short-, mediate- and long-term. To address these aims, we will study the effects of intrauterine chronic hypoxia and oxidative stress on the NO, CO and H2S related pathways of the cardiovascular system in guinea pigs. We will describe the NO, CO and H2S related pathways, its epigenetic changes and their roles as important regulators of function, structure and biomechanical properties of heart and vessels, under hypoxia induced-oxidative stress. The aforementioned will be done in animals gestated under IH, with or without antenatal melatonin treatment, and follow the cardiovascular function from fetus to adulthood. The methodology is an in vivo non-invasive evaluation of the function and structure of the cardiovascular system (ultrasound); an ex vivo function and biomechanical characterization of heart and arteries (Langendorff, wire myography, biomechanical tests); and in vitro determinations of genetic, protein and epigenetic expression in heart and several vascular beds; at different stages of life. These approaches will permit us to correlate and integrate the short-, mediate- and long-term cardiovascular effects related to the gasotransmitters pathways, in the offspring gestated under chronic hypoxia. In addition, we will evaluate a supported treatment with melatonin, to prevent intrauterine growth restriction and cardiovascular impairment after IH exposure, to test the relationship of gasotransmitters pathways with intrauterine oxidative stress. We expect to unravel the mechanisms underlying IH- induced cardiovascular reprogramming focusing on oxidative stress and gasotransmitters, in order to potentiate melatonin treatment as a possible therapy in hypoxia related complicated pregnancies, either at high altitude or lowlands. This grant will effectively provide a valuable resource for the scientific and clinical community to pursue the understanding of cardiovascular NCDs programmed by intrauterine hypoxia, a worldwide burden still without effective therapeutic approach. Furthermore, this will add knowledge to the foundations for the development of novel therapies for intrauterine hypoxia, and the prevention of CV risk in fetuses, neonates and adults.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Se conciben como laboratorios que facilitan herramientas de fabricación avanzada y capacidades a la comunidad en general, pudiendo ser más enfocados a emprendedores, empresas e institutos de investigación. Una característica común es que sirven como plataforma para estimular el aprendizaje y la invención en la comunidad. Las máquinas y capacidades técnicas instaladas en estos laboratorios brindan la oportunidad de encontrar soluciones innovadoras a problemas comunes y ser incubadores de microemprendimientos que resuelvan problemas de forma innovadora y sustentable. El primer laboratorio de fabricación digital, junto con el concepto FabLab, aparece en el MIT (Massachussets Institute of Technology, Estados Unidos) en el año 2000. Actualmente, existe una red mundial de alrededor de 3000 FabLabs distribuidos en 5 continentes. En Chile se pueden encontrar 17 de estos laboratorios, la mayoría de ellos concentrados en la Región Metropolitana; 2 en la Región del Maule y ninguno en la Región de O’Higgins. La ausencia de un laboratorio regional está en concordancia con estadísticas del año 2016 que reportan apenas 118 m2 de espacios dedicados a innovación en la Región de O’Higgins frente a 27 936 m2 en la Región Metropolitana. En ese contexto, la Región de O’Higgins es la segunda región con menor superficie dedicada a innovación. La instalación de un laboratorio de fabricación digital en la Región de O’Higgins se identifica como una gran oportunidad para promover la innovación, brindando acceso a equipos y a capacitaciones sobre herramientas de fabricación avanzada a industrias y emprendedores regionales.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
