    Analyzing the relationship between social network space and activity space. Evidence from 4 databases in Chile
    (Universidad de Concepción, 2023) Medina de Cortillas, Diego Emiliano; Carrasco Montagna, Juan; Astroza Tagle, Sebastián
    In transportation sciences, it is usual to study people's trips for work, study or shopping purposes. However, not enough attention is paid to the social or leisure activities that people engage in. Moreover, it is not usual to see studies or reports that relate activities to people's social networks. This is why this study aims to relate the spatiality of activities, the time dedicated to each activity and the characteristics of each individual's personal social networks. This is relevant in order to better understand daily mobility based on its reasons and not only its destinations. The objective of this thesis is to describe and relate mobility, time use and social networks for 4 different databases collected in the years 2008, 2012, 2015 and 2018. The central hypothesis is that people's activity space is related to the geography of the social network and to the attributes of the social networks. For this, the study subdivides the types of activity into 3 categories: productive activities are those related to production such as studying and working ; the second type of activity consist s of reproductive activities which make biological life endure from one generation to the next or within the same generation (housework, shopping, window shopping, dropping off or picking up, caring, food preparation, etc.). Finally, leisure activities are those where people engage in socializing activities between the individual and his or her social network or leisure activities (visits, religion, pubs, leisure, telephone, cinema, etc.). The results obtained underline the importance of reproductive time within the home as a time that reduces the probability of leaving the home, restricts the time dedicated to leisure activities and, in addition, restricts the magnitude of activity spaces both in terms of number of places and distances traveled. On the other hand, it accentuates the group of women as the people who have the most limitations when leaving the home and who are also the ones who allocate the most reproductive time within the home. Finally, the role of the family social network is highlighted as the socio spatial context that promotes the mobility of each individual in their daily lives.

    Segregación socioespacial y tipologías de barrio para 6 comunas del área metropolitana de Concepción.
    (Universidad de Concepción, 2020) Medina de Cortillas, Diego Emiliano; Carrasco, Juan Antonio
    La siguiente investigación busca caracterizar la segregación socio espacial y la estructura morfológica que presentan 6 comunas del área metropolitana de Concepción. En el desarrollo de la investigación se mostraría el contexto histórico de América Latina y cómo las políticas públicas del siglo XX lograron conformar una ciudad industrializada con consignas de equidad, para posteriormente ser abatidas por políticas de corte neoliberal generando estructuras urbanas segregadoras. Los propósitos de la investigación son cartografiar las zonas segregadas de las comunas y agrupar según las características sociodemográficas del ´área (Escolaridad del jefe de hogar, Tasa de inmigración, Diversidad de usos de suelo, Hacinamiento, Distancia a los Bicentros). Para aquello se ocuparán mapas auto-organizantes que agruparán las zonas más parecidas según su contexto sociodemográfico. Los principales resultados arrojan que en la detección de la segregación se puede categorizar en 5 tipos de barrios los cuales gradualmente se diferencian de mayor a menor calidad de los indicadores, presentando zonas altamente integradas y zonas altamente segregadas, coincidiendo estas últimas con procesos históricos de la política de vivienda y la violencia institucional a partir del golpe de estado del 11 de septiembre de 1973.
