This summer, I worked with Professor Ge and Jiebei Luo, and my peer Madhav Jha on the U.S. Airline project. Specifically, we aim to discuss the product quality and consumer response using the tweets that we scraped from the Twitter API. In case of the airline industry, the number of airlines in a competitive market is low due to scale economies. Some airlines maintained their monopoly status on specific routes, and their failure to improve service quality (worsening delays) has raised nation-wise concerns and increased consumer dissatisfaction. As social media platforms (e.g., Twitter in our case) provide large amount of text data, we are able to locate tweets directed at a specific airline through mentions (@). See 1-1 below for sample tweets. Considering the short span of the program and the exploratory nature of our project, we limited our data coverage and focused on two chosen airlines, Alaska Air and JetBlue (Delta and Southwest Air in Madhav’s case), on a sample date pre-covid (Nov 12, 2019).

1-1 Sample tweets

To retrieve historical tweets, we utilized the Twitter API, a platform that allows you to find and retrieve, engage with, or create a variety of different resources including the following: user ID, time created, text, and more. 1-2 shows an example of the tweets we pulled. Since many tweets contains URLs, digits, and other things that might disrupt the sentiment analysis, we preprocessed the tweets to trim them and make them ready for future steps.

1-2 Retrieved Tweets

The purpose of preprocessing is to get rid of any unwanted/irrelevant text elements. To conduct sentiment analysis, we used two different toolkits, TextBlob and Vander, in order to compare between results. However, computer programs have problems recognizing things like sarcasm and irony, negation, jokes, and exaggeration – things that are easy for a human to sense and identify. Failure to recognize these things can skew the results. And since some tweets contains multiple mentions, even when the overall sentiment is negative, the sentiment toward a specific airline is not necessarily negative. Therefore, after putting the texts through automated analyzing programs, we manually identified each of the tweets. See 1-3 for an example when sarcasm cannot be detected by the programs.

1-3

Our next step would be to create visualizations to help illustrate our analysis. This summer has been really rewarding as I had zero experience in scraping data, preprocessing data, and text/sentiment analysis prior to this project. Exploring new areas is always exciting and learning about the airline industry is so relevant to our day-to-day life. Even though the research has just started, and we still have a long way to go before we draw any conclusion, being able to start from scratch and building new skills and knowledge on every step of the way is beyond precious. I would like to thank Professor Ge and Jiebei for this wonderful opportunity and experience.

This summer, I worked with Professor Michael Walsh on his project “China Reimagined: An Alternative History in Nine Parts.” While refining his first-year writing seminar “China Reimagined,” the project will also be expanded into a book that provides alternative perspectives of Chinese history than the more traditional chronologies.

The project is inspired by 洛書 (LuoShu), an ancient mystical chart that appeared from the Luo River in central China.

Our primary task was to explore the concept of “China” through 9 themes, beginning with “territory” 國, which concentrates broadly on Chinese cosmology, and ending with “people”民.

The challenge of the project is that it’s impossible to give a comprehensive conclusion of what China is and who ‘counts’ as Chinese. We worked together to figure out the most appropriate nine themes for the book project and the appropriate Chinese and English titles for each topic. I also researched the etymology of relevant Chinese terms.

Besides tracing the history of LuoShu, I mainly worked to find primary and secondary resources in Chinese both in the library and online. Professor Walsh gave me much freedom to explore these topics and I found myself dwelling on some topics like “territory” and “city” while spending less time on others. I then translated, summarized, and annotated  the information I found.

For me, it was also about learning the process of exploring academic research and about research material selection. Additionally, translating the texts was a surprisingly helpful way of learning. I found myself knowing a lot more than merely “reading through the words.” It almost feels like the 8 weeks of research just started yesterday. I want to thank Professor Walsh for making this a wonderful experience. 

This summer, we worked with Professor Frye and Professor Kagy to research the economic consequences of childhood exposure to environmental toxins. We primarily focused on evaluating whether early exposure to lead would cause differences in intergenerational mobility, occupational rank, and total years of schooling. 

The project involved constructing a highly intricate data set that pulled together information on people and towns in the northeast, where the integration of central water systems was prevalent around the turn of the twentieth century and the use of lead and non-lead materials for the municipal pipes varied. We used IPUMS to collect census data for the late nineteenth and early twentieth centuries, the Census Linking Project to probabilistically match people across censuses, the Census Place Project to identify where these people lived, and two books that organized information on cities’ water systems and water chemistry. 

Due to the large sizes of the data, we relied on Amazon’s Web Server to run code in RStudio that could compile and build our data set. Our final data set allowed us to identify children in the Northeast as living in either lead or non-lead cities, and then track this cohort overtime to evaluate their outcomes in adulthood.

Exploratory data analysis, involving graphs, maps and summary statistics tables, shows early implications that exposure to lead in childhood does have negative long-term economic consequences. For example, the average income in 1940 for a child exposed to lead in 1900 was $6062 less than the average for a child who was not exposed to lead via city service pipes.

Figure 1: This map visualizes where lead pipes were located in Maine, Rhode Island, New Hampshire, Massachusetts., Pennsylvania and New York.

This project also sparked an interest in current-day exposure to toxins and made us more cautious about what we may be consuming in our day-to-day lives. Moreover, this project was a very rewarding experience that enabled us to greatly improve our coding skills and collaborate with our professors, who offered deep insights into working in research. We are grateful that we had this opportunity to learn first-hand about economic research and be part of an exciting and innovative project.

My work over the Ford period focused on understanding the mechanism described in a paper by Chaumont and Shi, 2022, by replicating it using python. Initially, it was challenging for me to sufficiently understand Chaumont and Shi’s work without much prior knowledge of the field of job transitioning and wealth study. With the aid of Professor Argudo who patiently answered all my questions over several meetings, I grasped enough to start my own replication. The process was still demanding, but through trials and errors, I have acquired similar results using the method of Value function iteration (VFI). I am familiar with VFI thanks to ECON 304 with Professor Argudo from the previous semester, but tackling such a task with so much independence as I have in the Ford program was something I have never done before. For me, It was a pleasure to receive this opportunity through Ford to assist in professor Argudo’s research and challenge myself outside of my comfort zone.

This summer, I worked with Professor Paravisini-Gerbert and Professor Aronna to prepare a translation of the first volume of Gonzalo de Oviedo’s General and Natural History of the Indies and Ocean Sea for publication. As the royal historian for Spain in the early 1500s, Oviedo produced the first comprehensive history of Spanish America. Covering local flora and fauna, indigenous practices, political scandals, brutal Spanish colonization, and much more, this account offers a vibrant and information dense view into this violent, fascinating, and formative period of American history, and I feel beyond lucky to have helped with the first ever complete translation of this work.

One of my responsibilities this summer included assisting with proofreading and editing the translation. This project was a collaborative effort, with many different students translating different chapters; this meant that despite each translators’ high quality work, sometimes the same word would be translated several different ways across chapters. We cross-referenced each chapter to the original text while editing, ensuring the final product would be a faithful and cohesive adaptation. 

A view of the editing process–– we were changing the translation of “oidor” from “judge” to the more accurate “high court judge.”

Once the chapters were edited and triple checked, I would help upload them to Scalar. Scalar is a website that flows like a book, and my duties included adding content, styling the website, and working out any bugs along the way. Through this process I was exposed to a wide variety of art from early Spanish America, learned the basics of CSS, and gained experience building a website.

An example of how the books look on Scalar.

However, above all, I was able to catch a glimpse of what life was like in early Spanish America, complete with details I would have never otherwise imagined. Sometimes horrifying, sometimes snarky, and always interesting, this Historia is a treasure trove of information and I am grateful to have played a role in bringing it to a wider audience.

This summer, I worked with Professor Kagy on developing an economics seminar on inequality and discrimination.

The project consisted of a few primary tasks: find academic and popular press publications/media sources for the class, create class materials for those sources, and build out the applied econometrics that will be taught alongside the class materials.

Inequality and discrimination, in the US at least, have a long, complicated, and sad history tied to status, subversion, and power. While many are fortunate, far too many, especially people of color, members of the LGBTQIA+ community, women, immigrants, etc., have lived, worked, and struggled in systems of power rigged against them. For example, we can look back at the early to mid-20th century redlining policies that froze people of color out of the housing market. Since assets and wealth, such as a home, build wealth and intergenerational wealth, the impacts of redlining are still being felt today (see Netflix Explained racial-wealth gap & billionaires).

Moving beyond the history and literature of inequality and discrimination, much of my time was spent working with US Census data to create visualizations of inequality over the last 50 years.

The census data I worked with focused on income, and I was able to visualize numerous examples of inequality. I found it immensely striking how evident the inequality was, even after controlling for exogenous variables. As someone who wants to work in the development/general helping people fields, this project has given me further impetus to pursue this path. In addition, after being abroad, working on this project provided a much-needed refresher on coding and econometrics.

I hope my contribution to this project helps whoever takes this class next spring understand and appreciate the complexities of inequality and discrimination, and perhaps push them to do more to help.

Paulo Reglus Neves Freire (1921-1997)

“Because love is an act of courage, not of fear, love is commitment to others. No matter where the oppressed are found, the act of love is commitment to their cause – the cause of liberation.”

– Paulo Freire

Known as the leading advocate for critical pedagogy, Paulo Freire was a Brazilian author, philosopher, and educator who championed education in the fight for liberation, equity, and peace. Through close readings of Freire’s work, explorations of multimedia analysis of his concepts, and dialogues (both academic and community-based) with practitioners of Frerian pedagogy, Professor Hantzopoulos and I inquired: How has Freire’s theories been implemented into practice in educational settings?

Freire’s Pedagogy of the Oppressed (1970) is a seminal, foundational, and revolutionary text from which scholars, activists, and educators draw techniques and theories to institute and sustain social change. With this text as a basis, Professor Hantzopoulos curated a shortlist of books as a catalyst point for further exploration: Education for Critical Consciousness and Pedagogy of Freedom: Ethics, Democracy, and Civic Courage both by Freire, Teaching Community: A Pedagogy of Hope and Teaching Critical Thinking: Practical Wisdom both by bell hooks.

Paulo Freire in the praxis of a “culture circle.”

These books guided me in creating an annotated bibliography of fifty sources ranging from teaching guides, lesson plans and activities, journal articles, book chapters, research databases, videos and documentaries, to podcasts with a focus on the implementation of Freirian theory in educational settings. Each source either contextualized, criticized, or built upon Freire’s ideas. This open-ended exploration allowed me to not only track the ways in which people have employed Freirian practice in everyday life but also track the evolution of Freire’s ideas as they were put through an iterative process of trial, error, and revision in varying contexts.

With this complex and rich bevy of sources, I created an interactive website that chronicles this iterative process; this process revealed to me that Freire’s theories and praxis holds a cyclical paradigm. Paulo Freire’s teachings are still relevant today because they emphasize the powerful influence education has in shaping citizens and society.

“Looking at the past must only be a means of understanding more clearly what and who they are so that they can more wisely build the future.”

– Paulo Freire

Carissa Kolcun ’25 and John Murphy the Philip and Lynn Straus Curator of Prints and Drawings

This summer I assisted John Murphy with preparing materials for a fall intensive class and curating the fall spotlight exhibition on the Women’s Studio Workshop. While both projects divided my time, many of the materials overlapped allowing for cross-thought on how the content could engage each other within a class framework.

The Women’s Studio Workshop (WSW) is a studio and arts space in Rosendale, NY. It was founded in 1974 as a women-centered art space and now, under new leadership, WSW has begun to tease out what exactly “woman-centered” means in a contemporary context. In approaching WSW as the subject of the spotlight exhibition, we were interested in both responding to this question alongside telling a brief history of the Workshop. In using the spotlight space, we were also engaging Vassar’s connection to WSW as a repository for all their artist’s books, as well as engaging WSW’s role in the broader Hudson Valley arts community

In addition to this project, I also planned one class session for Paper Protests, the fall intensive. After a visit to Interference Archives in Brooklyn, I became interested in the spatial theater that posters create when in public space, and how that theater mitigates the original intention of the posters. As a community-centered organization, WSW has collected posters created for various programming and events since its inception. WSW became an outlet to explore spatial theater on a micro scale, while I found readings to guide a discussion of spatial theater on a macro scale.

Between all the research, I visited many locations across the Hudson Valley, including the WSW archives, Art Omi, and Bard CCS. I’m very thankful to John Murphy as well as the rest of the Loeb staff and look forward to further exploring the curatorial process in future endeavors.
