    Coping with Natural Disasters and Urban Risk: An Approach to Urban Sustainability from Socio-Environmental Fragmentation and Urban Vulnerability Assessment
    (Emerald Group Publishing Limited, 2014) Link, Felipe; Barth, Katrin; Harris, Jordan Michael; Irarrazaval Irarrazaval, Felipe; Valenzuela, Felipe; Welz, Juliane; William G. Holt; CEDEUS (Chile)
    Purpose - Cities have been exposed to a variety of natural disasters such as flooding, extreme temperatures, storms, earthquakes, and other natural shocks, and have had to respond and adapt to such pressures over time. In the context of global climate change, natural disasters have increased across the globe. Apart from climate change, many urban environments in Latin America are experiencing significant transformations in land use patterns, socio-demographic change, changing labor markets, and economic growth, resulting from recent decades of globalization. Such transformations have resulted in the internal fragmentation of cities. In this context, the purpose of the present chapter is to demonstrate the importance in both theoretical and methodological terms, of integrating the concept of socio-environmental fragmentation into urban vulnerability research in order to make progress toward higher degrees of local sustainability in those areas of the city that suffer natural disasters and fragmentation. Methodology/approach - A mixed methods approach is used in order to combine different technical issues from urban and climate change studies. Findings - The findings are related to the importance of an integrated approach, regarding the complexity of urban life, and the relationship between the urban, the social, and the environmental phenomenon. Social implications - This chapter relates to the revisit of the current state of preparedness and to determine whether further adaptations are required. The authors understood that these kinds of mixed approaches are necessary in order to understand the new complexity of urban processes.

    From Community to Public Familiarity: Neighborhood, Sociability, and Belonging in the Neoliberal City
    (SAGE PUBLICATIONS INC, 2021) Link, Felipe; Senoret, Andres; Valenzuela, Felipe
    Current urban neoliberalism processes have shaped and changed contemporary cities, including the local scale's built environment and social relations. This article aims to study how such transformations affect local sociability by analyzing the effects of neighborhoods' morphology and socio-demographic characteristics on different forms of interactions and how they affect the sense of belonging. Taking the Metropolitan Area of Santiago, Chile, as a case study, we gathered secondary data on urban morphology and surveyed ten neighborhoods to measure sociability patterns. The results obtained from multilevel logistic regression models show that time living in the neighborhood and public pedestrian space is the most critical factor affecting neighborhood sociability. Moreover, instead of local ties, public familiarity is the form of sociability with the most substantial effects on a sense of belonging. We conclude that recent neighborhoods, formed by neoliberal urbanization, tend to discourage neighborhood sociability and a sense of belonging.

    Optimal length of triple therapy for H pylori eradication in a population with high prevalence of infection in Chile
    (BAISHIDENG PUBLISHING GROUP INC, 2007) Riquelme, Arnoldo; Soza, Alejandro; Pedreros, Cesar; Bustamante, Andrea; Valenzuela, Felipe; Otarola, Francisco; Abbott, Eduardo; Arellano, Marco; Medina, Brenda; Pattillo, Alejandro; Greig, Douglas; Arrese, Marco; Rollan, Antonio
    AIM: To compare the efficacy of 7-d versus 14-d triple therapy for the treatment of H pylori infection in Chile, with a prevalence of 73% in general population. METHODS: H pylori-infected patients diagnosed by rapid urease test, with non-ulcer dyspepsia or peptic ulcer disease were randomized to receive omeprazole 20 mg bid, amoxicillin 1 g bid, and clarithromycin 500 mg bid for 7 (OAC7) or 14 (OAC14) d. Primary outcome was eradication rate 6 wk after the treatment. Subgroup analysis was carried out considering the eradication rate among patients with or without peptic ulcer disease and eradication rate among smokers or non-smokers.

    Segregation, structure and social composition of the metropolitan area of Santiago, Chile. Methodological complexity in the study of social differentiation in space
    (PONTIFICA UNIV CATOLICA CHILE, INST GEOGRAFIA, 2015) Link, Felipe; Valenzuela, Felipe; Fuentes, Luis
    The study of social differentiation in space requires significant theoretical and methodological definitions in order to address the complex relationship between space and society. In that regard, it is possible to identify different lines of research that claim to account for this relationship. The aim of this paper is to present an analysis of social differentiation in space in the metropolitan area of Santiago using socio- spatial typologies. The results indicate that, although it is possible to identify some general patterns that are similar when using different approaches, typology analysis can better address the social complexity of metropolitan space. Finally, this paper aims to account for the centrality of the variable occupation as a factor of social differentiation in the urban context.
