Sociophonetic Variation in the Production and Perception of Obstruent Voicing in Buenos Aires Spanish Sociophonetic Variation in the Production and Perception of Obstruent Voicing in Buenos Aires Spanish by Marcos Rohena-Madrazo A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Linguistics New York University September, 2011 Lisa Davidson c Marcos Rohena-Madrazo All Rights Reserved, 2011 Dedication lunes, martes, miercoles:´ tres jueves, viernes, sabado:´ seis ¡y domingo siete! Para ti, Abuela. iii Acknowledgements First of all, I would like thank each and every one of the participants in this investigation, who selflessly donated their time, energy, and speech. Without their generosity, this dissertation would not have been possible. I would like to express my deepest gratitude to my advisor, Lisa Davidson. Thank you for being such a patient guide, for always having your door open to discuss new ideas, for encouraging me to step back and question my assumptions, and for instilling in me a passion for experimental research. I am truly grateful for all you have taught me and am honored to have been your student. I would also like to thank the other members of my committee: Gregory Guy, for always bringing it back to the big picture; John Singler, for delivering the harsh (and well-deserved) critiques in a way that always made me smile; Susannah Levi, for her detailed comments that provided a new perspective; and Laura Colantoni, for believing in my work and offering words of encouragement at just the right time. Your input throughout this process has undoubtedly made me a better scholar. The inspiration for this project, I owe to Mercedes Paz. Thank you for your in- valuable support and for all the wonderful moments we shared. Likewise, I would like to express my heartfelt appreciation to the Paz and Fink families for their hospitality iv and boundless generosity. Thank you also to Santiago Kalinowski, Helgal´ıs Ramos, Giselle Roman,´ Lourdes Lavaque,´ Pedro Rodr´ıguez, Daniela Laur´ıa and all my friends in Buenos Aires, native and transplanted, who made me feel right at home. I am grateful to Sean Martin, Jason Shaw, Tuuli Morrill, Kevin Roon, Jocelyn Doxsey, Andrea Cattaneo, Stacy Dickerman, Carina Bauman, Vincent Chanethom, Lu- ciana Muniz, Kyle Major, Libby Coggshall, Sang Im Lee, Jon Brennan, Suzanne Dikker, Luiza Newlin-Lukowicz, Emily Nguyen, Cara Shousterman, Eytan Zweig, Lisa Levin- son, Tom Leu, Jen Nycz, Sonya Fix, Dan Lassiter, Txuss Mart´ın, Philipp Angermeyer, Laziz Nchare, Oana Savescu, Mike Taylor, Silvia Perpin˜an,´ Meghan Armstrong, Hilary Barnes, Eva Suarez,´ Ryan LaBrozzi, Ana de Prada, and the other fellow graduate stu- dents at NYU Lingustics and other departments for the hearty meals, numerous drinks, and fruitful discussions that we have shared throughout these years. Also, many thanks to the professors at NYU Linguistics for promoting such a collegial environment, in par- ticular, to Renee´ Blake and Louise Vasvari´ for helping me uncover academic interests I never knew I had. I am also grateful to Mar´ıa Vaquero, who taught at the University of Puerto Rico, for being the first to usher me into the endlessly fascinating field of Hispanic Linguistics. I owe many thanks to my research assistants, Linden Bairey, Autumn Gerami, Scott Lawrence, Sophia LeFraga, Joe Raite, Matt Sauter, Jess Tauber, and Molly Trisler, who helped me through the less glamorous aspects of phonetics research. Thanks to David Pe and my fellow Grad Halls Staff, Bryan Brazeau, Elaine Tang, Jeff Steen, Lauren Aument, Monica Putt, Olga Sanchez-Eltell,´ Shavanna Calder, Theo Mitchell, and Thomas Fai, for cheering me on and making my last year at NYU so memorable in such an unexpectedly delightful way. v I am especially grateful to Jeff Crumbliss, who was there every week to help me surpass the hurdles and celebrate the successes of the dissertation process (and of life in general!). I cannot imagine what it would have been like without your help. Thank you for making me learn so much about myself. I am very fortunate to have such a fantastically varied group of friends keeping me afloat. Many thanks to Juan Carlos Guzman,´ Omar Acevedo, Joel Maysonet, Marla Tor- rado, Yari Otero, Carmen Otero, Chetzil Penalverty,˜ and to all my friends from Puerto Rico, who have supported me on and off the island. In particular, a tidal wave of grat- itude goes out to Lorna Torrado for being the best pep-talker in the universe, from the first chapter to the defense. And Sara Ortiz, I will be thanking you many more times than just once a month. Many thanks to my NYC friends, Fu Chung, Andrew Solomon, Chris Mark, Emily McNeil, Jill Emmanuele, Dave Bowles, Josh Siegel, Vicky Cattani, and Pablo Ariel for keeping me from falling prey to the grad school vortex. Thanks to Tricia Irwin for showing me the LATEX ropes, without her help this dis- sertation would have never been written, literally. Thanks to Kara Becker for blazing trails and showing me that it can be done. Thanks to Maryam Bakht, whose quinces and company got me through my segmentation and much more. Amanda Dye’s G-chat banter, dependably full of football and Spanishness, made the late night work sessions much more enjoyable. Gracias y ¡hala! Special thanks to Javier Uriarte for being such a faithful friend, from across the block or across globe, through the NYU experience and beyond. We have overcome! If I am the onset, Danny Erker is the coda. Our fricative dork-out sessions have been, without a doubt, the most intellectually stimulating (and fun!) part of the dissertation process. I look forward to many more, my friend. vi I am particularly indebted to Miquel Simonet for teaching me so much about lin- guistics research at every level, from the most abstract theoretical questions to the most concrete scripting code. You seamlessly embody the role of friend, colleague, and men- tor; for this I am deeply grateful. One person has been a constant not just in my academic career but in my life ever since I started this roller coaster called graduate school: Amy Wong. There is no one in the world whose interests/obssessions overlap so perfectly with mine. Truly, a match made in foodie-linguistics heaven. Sharing with you offices, holidays, thoughts, theo- ries, mooncakes, guavacakes, and countless hours of conversation has been an immense pleasure. Thank you so very much for being my best friend throughout. Many thanks to my family: to Abuela Alicia for showering all of us with uncondi- tional love, to Abuelo Santos for always telling me ¡usted es de los buenos!, to Giovanna, Mar´ıa, and Cuqui for showing me that I can do it too, to Mar´ıa del Mar for always check- ing in, to titi Sunchi for her illuminating cheer, to An´ıbal for encouraging me by means of ¡termina!, to Ana Cecilia for always wanting to talk shop, and to Larisa for being the sister I never had. I am very fortunate to have all of you in my life. Finally, I would like to thank my parents Gloria Madrazo and Ricardo Rohena for inspiring and motivating me in the most of diverse ways. No one has been more influ- ential in my life than you. I am eternally grateful for your unwavering love and support. ¡Los quiero infinitamente! vii Abstract This dissertation presents an instrumental study of variation in fricative voicing in Buenos Aires Spanish (BAS), particularly with respect to the devoicing change of the postalve- olar fricative: /Z/>/S/. It proposes a novel way of determining the completion of this change by comparing the percentage voicing of the postalveolar fricative to that of /s/, thus providing a system-internal benchmark for voicelessness in a language without a fricative voicing contrast. The findings from the production study show that there is still much variation in the voicing of /Z/ that is both socially and phonetically conditioned. Although the change has reached completion only in the younger middle class group, all other social groups show evidence that the devoicing change is still progressing. Cross language discrimination experiments using Portuguese stimuli were conducted to explore the effects that socially conditioned variation and positionally defined allo- phonic variation in obstruent voicing may have on the delimitation of perceptual cate- gories used to discriminate non-native obstruent voicing contrasts. The results from the ABX task show that, instead of improving the discrimination of Portuguese /S/-/Z/, hav- ing socially differentiated variation in the native speech community actually hinders the discrimination of this contrast, regardless of the listener’s social background. Listen- ers, regardless of age and social class, do not seem to tap into the socially conditioned viii differential distribution of [S] and [Z] in BAS in order to discriminate the non-native contrast. The goodness rating task results show that listeners who maintain the voicing of /Z/ in their production give Portuguese /S/ significantly lower ratings than Portuguese /Z/. However, the converse is not true: listeners for whom the /Z/>/S/ change has been completed give similarly high ratings to both /Z/ and /S/. Rather than being determined by social differences, the evaluation of the variation (/S∼Z/) seems to be affected by the listener’s own production. The more innovative speakers in the devoicing change seem to have a more expansive postalveolar fricative perceptual category, whereas the conservative speakers’ category has a smaller range of acceptable realizations. ix Contents Dedication iii Acknowledgements iv Abstract viii List of Figures xv List of Tables xx List of Appendices xxiv 1 Introduction 1 1.0 Overview . 1 1.1 Background on ye´ısmo in Buenos Aires . 3 1.1.1 Historical development: J > Z > S ...............

  • The South–South Remittance Corridor Between Argentina and Bolivia
    The South–South remittance corridor M Also available online at: R between Argentina S http://publications.iom.int/bookstore 49 and Bolivia South–South remittance corridors still remain a largely unexplored research area, despite the fact that for a few years already, international organizations, such as the International Organization for No. 49 Migration and the World Bank, have been highlighting the importance of South–South migration and remittance flows. In South America, the Argentina–Bolivia corridor is the third most relevant South– South corridor in terms of annual volumes, after Venezuela–Colombia and Argentina–Paraguay. This publication provides a diagnostic report on the access to and use of remittance services by Bolivian migrants in Argentina, showing the main obstacles and challenges faced to achieve a productive use of remittances. The study examines the legal and regulatory frameworks of remittance- related transactions, together with the sending process from Argentina to Bolivia, with its chain of intermediation and different money transfer schemes. Field research was carried out through a survey and qualitative interviews with Bolivian immigrants living in Greater Buenos Aires and Greater La Plata, divided into two sub-samples of clients and non- clients of microfinance institutions. Research outcomes highlight a series of ways for policymakers and international organizations to facilitate the flow of South–South remittances, from a standpoint of progressive financial inclusion of migrants and their families. This study provides key recommendations for public policies and actions aimed at maximizing the positive impact of remittances in terms of local development, focusing on two intervention pillars: financial education and transparency of the remittance services market.

  • Everyday Water Struggles in Buenos Aires: the Problem of Land Tenure in the Expansion of Potable Water and Sanitation Service to Informal Settlements
    Everyday Water Struggles in Buenos Aires: The Problem of Land Tenure in the Expansion of Potable Water and Sanitation Service to Informal Settlements Florencia Almansi, Ana Hardoy, Gustavo Pandiella, Ricardo Schusterman and Gaston Urquiza (Instituto Internacional de Media Ambiente y Desarrollo, IIED-America Latina) A study commissioned by WaterAid (UK) 1. Introduction Joveli, Elisa and Cristina are women from three informal settlements in the Greater Buenos Aires and Greater La Plata Area. This area can be visualised as a continuous urban and sub- urban area of three rings extending from the City of Zarate down to La Plata, some 100 kilometers across, facing the river. At the centre of the rings is the city of Buenos Aires, the federal capital. Elisa lives in San Fernando, which is in the north of Buenos Aires. Joveli lives in Moreno, the westernmost municipality in the second ring. Cristina is in La Plata, at the end of the conurbation on the southeast. The stories of these three women, and the communities where they come from, reveal much about the drama and ‘everyday struggles’ over land and access to services by poor people in unplanned, informal and illegal settlements. Joveli, Elisa and Cristina have led nearly parallel lives. They all live with their children in these informal neighbourhoods settled mostly by poor migrants in constant search of employment while living in precarious, unhealthy conditions. All three have had difficult lives marked by poverty and insecurity, that have been made even worse by the treatment they get as women. Yet, these three have emerged as able local leaders, and are intensely proud of being women.

  • Transportation Investments in Argentina Impacts on Social and Economic Development
    TRANSPORTATION INVESTMENTS IN ARGENTINA IMPACTS ON SOCIAL AND ECONOMIC DEVELOPMENT I-TED 2014 – INTERNATIONAL TRANSPORTATION ECONOMIC DEVELOPMENT CONFERENCE April 9-11, 2014 Dallas. Texas Haydée A. Lordi WORLD ROAD ASSOTIATON –NACIONAL COMMITTEE- ARGENTINA ASOCIACIÓN ARGENTINA DE CARRETERAS Contents Introduction Study Area Socioeconomic characterisation Demographic analysis Transport Infrastructure Diagnostic of Mobility Case Study : BRT La Matanza (Nacional Road Nº 3 Avda. Brig. General Juan Manuel de Rosas) Conclusions and recommendations INTRODUCTION This presentation aims to show the scope of the research that I undertook in 2010, together with other professionals:“Study of technological measures and applications to maximize the installed capacity of the transport system” (Lordi , Ortiz , Russomanno and Bortolín), awarded first prize by the World Engineering Congress 2010 corresponding to the Chapter “Large metropolis and its infrastructures”. The main objective of the study was to provide a detailed analysis of the transport infrastructure in the Metropolitan Area of Buenos Aires (AMBA) in Argentina, and to propose solutions to optimize the existing system capacity, without resorting to strategies focused on expanding capacity, especially road capacity. The study bases its justification on the need to moderate transport’s impacts to ensure sustainable transport in the AMBA. The research designates areas that warrant greater development and formulates the recommendation of encouraging development measures for the local context. Finally, it illustrates the application of the mentioned recommendations to a particular regional case study: “Development of a Bus Rapid Transit (BRT) on National Route Nº 3 – La Matanza to Autonomous City of Buenos Aires”. Outcome of this study: The government of Argentina has recently received a loan from the World Bank to implement a 26 km modern bus passenger transport prioritization system in the Municipality of La Matanza, the largest BRT ever built so far in Argentina.
