Abstract The digitization of several million books by Google in 2011 meant the popularization of a new kind of humanities research powered by the treatment of cultural objects as data. Culturomics, as it is called, was born, and other initiatives resonated with such a methodological approach, as is the case with the recently formed Digital Humanities or Cultural Analytics. Intrinsically, these new quantitative approaches to culture all borrow from techniques and methods developed under the wing of the exact sciences, such as computer science, machine learning or statistics. There are numerous examples of studies that take advantage of the possibilities that treating objects as data has to offer for the understanding of the human. This new data science that is now applied to the current trends in culture can also be replicated to study more traditional humanities. Led by proper intellectual inquiry, an adequate use of technology may bring answers to questions intractable by other means, or add evidence to long held assumptions based on a canon built from few examples. This dissertation argues in favor of such approach. Three different case studies are considered. First, in the more general sense of the big and smart data, we collected and analyzed more than 120,000 pictures of paintings from all periods of art history, to gain a clear insight on how the beauty of depicted faces, in the framework of neuroscience and evolutionary theory, has changed over time. A second study covers the nuances of modes of emotions employed by the Spanish Golden Age playwright Calderón de la Barca to empathize with his audience. By means of sentiment analysis, a technique strongly supported by machine learning, we shed some light into the different fictional characters, and how they interact and convey messages otherwise invisible to the public. The last case is a study of non-traditional authorship attribution techniques applied to the forefather of the modern novel, the Lazarillo de Tormes. In the end, we conclude that the successful application of cultural analytics and computer science techniques to traditional humanistic endeavours has been enriching and validating. ii Keywords Digital Humanities, Cultural Analytics, Machine Learning, Art History, Face Recognition, Beauty, Calderón de la Barca, Sentiment Analysis, Authorship Attribution, Lazarillo de Tormes. iii Co-Authorship Statement Chapter 2 is an article that has been already published in a peer-reviewed journal.

Prof. Suárez has motivated me to continue to strive for excellence particularly during the most challenging times, while providing a reality check of the trade-offs we all must assume at any point of a career. My colleagues, the faculty, and staff from the Department of Modern Languages and Literature, for fostering a kind of critical thinking that I was lacking, for making me realize the importance of knowing how the world has worked and how it currently works beyond the sciences, and for the discovery of how brilliant people can be, no matter their field of study. I would also like to thank my colleagues at the CulturePlex Lab, past and present: María, Miriam, Camelia, Shiddarta, Roberto, Diego and Élika. And the ones who I have shared most of my time and space with: Adriana, Antonio, Ben, David, Nandita, and Natalia. Thanks for making everyday a pleasure to go to work, for sharing your lives and circumstances with me, and for teaching me so much inglish. It has been a long trip, but I am happy to see they are not only excellent researchers and persons, but possibly friends for life. Josema, Gabi, and Fernando, with whom I have shared many virtual meetings, have also been extremely patient and understanding in both my excuses and changes of mood. My distant family: my father, my brothers Fernando, and Raúl, my sister Mirian, and my awesome nephew –who refers to me as “Uncle Javi from Canada”–, who have provided me with their unconditional love and heartwarming support at all times, regardless of whether or not they understood what was that I was doing or even why. This work is dedicated to them. And to my mom, la más Bort, who although sadly and hurtfully long vi gone, is still present in all my life successes and endeavours, and made me the person I am, with her pleasant and serene wisdom that only a great person can have, and who always supported every crazy and adventurous idea I had, even when that meant space and distance between us. My friends, mostly overseas, have offered their smiles, inside jokes, free nostalgia, words of encouragement, and good vibes in that of life always finds its way, and achievements and sharing them, are as important as enjoying the path while maintaining close those who we love. Their contribution has touched my heart and motivated me during the most difficult times. And to the love of my life, Esperanza, who, at the risk of sounding cliché, has provided me with the kind of unconditional, uninterested, and encouraging support that only she can and knows how to offer, despite of the good and bad times, through the good and bad times. And to the tiresome and simpleton dog, Nilo, who at times has forced me to go outside against my will, which almost always has been of help. In summary, my way on this dissertation has made me a more honest, humble, and critical person, and for that I am grateful. Through my collaboration at the CulturePlex Lab and the Hispanic Baroque Project, this research was generously supported by SSHRC and CFI. vii Table of Contents Abstract ............................................................................................................................... ii Co-Authorship Statement................................................................................................... iv Acknowledgments.............................................................................................................. vi Table of Contents ............................................................................................................

  • The New Urban Success: How Culture Pays
    The New Urban Success: How Culture Pays DESISLAVA HRISTOVA, Cambridge University, Cambridge, UK LUCA MARIA AIELLO, Nokia Bell Labs, Cambridge, UK DANIELE QUERCIA, Nokia Bell Labs, Cambridge, UK Urban economists have put forward the idea that cities that are culturally interesting tend to attract “the creative class” and, as a result, end up being economically successful. Yet it is still unclear how economic and cultural dynamics mutually influence each other. By contrast, that has been extensively studied inthecase of individuals. Over decades, the French sociologist Pierre Bourdieu showed that people’s success and their positions in society mainly depend on how much they can spend (their economic capital) and what their interests are (their cultural capital). For the first time, we adapt Bourdieu’s framework to the city context. We operationalize a neighborhood’s cultural capital in terms of the cultural interests that pictures geo-referenced 27 in the neighborhood tend to express. This is made possible by the mining of what users of the photo-sharing site of Flickr have posted in the cities of London and New York over 5 years. In so doing, we are able to show that economic capital alone does not explain urban development. The combination of cultural capital and economic capital, instead, is more indicative of neighborhood growth in terms of house prices and improvements of socio-economic conditions. Culture pays, but only up to a point as it comes with one of the most vexing urban challenges: that of gentrification. Additional Key Words and Phrases: culture, cultural capital, Pierre Bourdieu, hysteresis effect, Flickr Original paper published on Frontiers: https://doi.org/10.3389/fphy.2018.00027 1 INTRODUCTION The French sociologist Pierre Bourdieu argued that we all possess certain forms of social capital.

Cultural History Cultural history brings to life a past time and place. In this search, cultural historians study beliefs and ideas, much as What is Cultural History? historians do. In addition to the writings of intellectual elites, they consider the notions sometimes unwritten of the less privileged and less educated. These are reflected in the products of deliberately artistic culture, but also include the objects and experiences of everyday life, such as clothing or cuisine. In this sense, our instincts, thoughts, and acts have an ancestry which cultural history can illuminate and examine critically. Historians of culture at Yale study all these aspects of the past in their global interconnectedness, and explore how they relate to our many understandings of our varied presents. Cultural history is an effort to inhabit the minds of the people of different worlds. This journey is, like great literature, thrilling in itself. It is also invaluable for rethinking our own historical moment.

  • Measuring the Effects of Bias in Training Data for Literary Classification
    Measuring the Effects of Bias in Training Data for Literary Classification Sunyam Bagga Andrew Piper .txtLAB Department of Languages, Literatures, and Cultures McGill University McGill University [email protected] [email protected] Abstract Downstream effects of biased training data have become a major concern of the NLP community. How this may impact the automated curation and annotation of cultural heritage material is cur- rently not well known. In this work, we create an experimental framework to measure the effects of different types of stylistic and social bias within training data for the purposes of literary clas- sification, as one important subclass of cultural material. Because historical collections are often sparsely annotated, much like our knowledge of history is incomplete, researchers often can- not know the underlying distributions of different document types and their various sub-classes. This means that bias is likely to be an intrinsic feature of training data when it comes to cultural heritage material. Our aim in this study is to investigate which classification methods may help mitigate the effects of different types of bias within curated samples of training data. We find that machine learning techniques such as BERT or SVM are robust against reproducing certain kinds of social and stylistic bias within our test data, except in the most extreme cases. We hope that this work will spur further research into the potential effects of bias within training data for other cultural heritage material beyond the study of literature. 1 Introduction One of the challenges facing researchers working with cultural heritage data is the difficulty of producing historically representative samples of data (Bode, 2020).

    Managing Facilitation in Cross-Cultural Contexts March 2014 Managing Facilitation in Cross-Cultural Contexts: The Application of National Cultural Dimensions to Groups in Learning Organisations Matthew Jelavic, Dawn Salter Durham College Authors’ Contact Information Matthew Jelavic Durham College 2000 Simcoe Street North Oshawa, Ontario, L1H 7K4 phone: 905-721-2000 email: [email protected] Dawn Salter email: [email protected] Abstract: This paper provides an evaluation of the literature pertaining to national culture as it relates to pedagogy and the management of facilitation processes within groups in learning organisations. National culture plays a pivotal role influencing the cognitive processes of individuals and their comfort levels with various methods of facilitation management. By incorporating cultural analytics into the preparation of cross-cultural facilitative processes, facilitators can ensure management methods meet the unique needs of the participants. Key Words: Facilitation management, pedagogy, learning organisations, groups, training, national culture. Introduction The following paper explores a pedagogical approach to managing facilitation in relation to the theoretical concepts of national culture as originally developed by Geert Hofstede in his book Culture’s Consequences (Hofstede, 1980). Facilitation management is considered a core competency for those seeking to create and manage learning groups effectively and thus has become a popular pedagogical approach in the field of adult education
