Making Data More Used and Useful Undergraduate courses meet growing desire of students like Arielle Cunanan to master new technologies

By Mary Braswell

Each year, the Los Angeles Unified School District surveys its students, parents, teachers and staff, collecting hundreds of thousands of responses to questions about academics, safety, campus climate, emotional maturity and more.

A group of UCLA Luskin students got the unique opportunity to take a deep dive into this massive pool of raw data, identifying trends and developing insights to help principals better understand their schools’ strengths and areas for improvement.

The undergraduates and a select group of master’s students were enrolled in “Data Analysis for Educational Equity and Improvement,” offered for the first time in spring 2023. It’s one of a number of new offerings added to the Public Affairs curriculum to meet a growing demand for data and technology courses in the social sciences.

“Our students care about the world and want to make a difference. And one of the ways we learn about the world is exploring data sets,” said Meredith Phillips, the associate professor of public policy who developed the course with funding from the UCLA Chancellor’s Award for Community-Engaged Research.

“It’s a way of introducing students to the joy of becoming a scholar and a discoverer. And that’s what’s awesome about a research university, right? We essentially spend much of our time learning new things.”

The class was an upper division offering, but every Public Affairs major must complete basic coursework in the tools of quantitative analysis. Some love it; others do not.

But undergrads who get a taste of multivariate regression and chi-squared tests and simply want more now have additional courses to choose from, including open spots in graduate-level classes offered by the Luskin School’s Public Policy and Urban Planning programs. Many go on to learn a new type of foreign language, including R, Python and SQL.

“We’re getting a lot of students who are interested in the intersection of data science, tech and public affairs,” said Erika Villanueva, director of student services for the undergraduate program.

“We’re always thinking about what else we can do with our curriculum to support our students and to augment what we already offer. So, it just became a natural progression to add to our research methods offerings.”

Undergrad Arielle Cunanan said her first encounter with statistical analysis came through Public Affairs 60, “Using Data to Learn About Society,” a core course taught by Phillips.

“I never touched coding, never touched data science or analytics or computer science — nothing before 60,” she said. “And Professor Phillips was amazing. She really cared about teaching us about statistics and data analysis specifically for public affairs and social justice issues.”

When Cunanan spotted Phillips’ new course on educational equity, she jumped at the chance to enroll.

Working on behalf of a local elementary school, she and her team sharpened their proficiency in R, the programming language used to clean, organize and analyze the trove of survey data from LAUSD.

“It was hard. It was stressful. There were late nights. But then we got into the groove,” said Cunanan, who is majoring in psychology with a public affairs minor.

As patterns began to emerge from the enormous pool of data, the students set out to share their findings. That led to another key skill the course emphasized: In addition to being scientifically sound, the discoveries drawn from data must also be clearly and powerfully communicated.

Cunanan said her team was grateful for the opportunity to deliver two presentations to the school’s leadership team.

“The first time around, it was a bunch of charts, a bunch of graphs, different bar plots about each variable. It was just throwing numbers at them, statistics, percentages,” she said.

“And so, the next time around, we put ourselves in their shoes and said, OK, if we’re the administration, what do we need to see to help us create change at our school based on these variables? How can we make this more understandable so that it’s actually helpful?”

The team distilled the most relevant findings and conveyed them in a simpler presentation with bullet points, a few targeted graphs and time for fielding questions.

The experience has turned Cunanan into a true believer in the power of data to compel social change. She says she is bent on learning every coding language she can during her time at UCLA.

“Once you feel like you sort of get it, it really teaches you how to do hard things,” she said. “For me, if I could do this, I could do anything.”

“Data Analysis for Educational Equity and Improvement” arose out of Phillips’ desire to teach students how to find data-informed solutions to the pressing needs of local schools.

It’s the type of work she has conducted for more than a decade as co-founder of the Los Angeles Education Research Institute at UCLA Luskin, a role that has put her in close collaboration with LAUSD decision-makers. The annual School Experience Survey has been a crucial resource in Phillips’ research.

“We had heard a lot of folks at the district saying we wish these survey data were more used and useful,” she said. “So I thought that there might be a really neat opportunity to help train students in data analysis and data communication, then use them as analysts for particular schools and principals.

“They use real data with a real audience, an audience that genuinely cares.”

Winning the Chancellor’s Award for Community-Engaged Research allowed Phillips to hire a team of undergraduates to help her develop and test the curriculum.

“The class is a really hands-on, applied class. It develops problem-solving skills and logic skills and communication skills,” she said.

“The students learn that data has many kinds of roles to play. It’s useful for telling stories, making arguments and for trying to understand the world — and for making the world better in education.”

Matute Takes Waymo for Driverless Taxi Rides and Likes the Result

You can count UCLA Luskin’s Juan Matute among those excited about the potential of driverless vehicles, according to a recent article in the Los Angeles Times that rounded up reaction to a 24/7 robotaxi service recently launched in Santa Monica by Waymo.  The Silicon Valley-based driverless car company began offering Waymo One to the public in mid-October, and the reaction has not been universally positive. Matute, deputy director of the UCLA Institute of Transportation Studies, decided to experience it for himself, taking three rides with Waymo already. He’s a safe streets advocate who thinks self-driving vehicles are probably safer than human drivers. Vehicle automation can “help with some of the issues we have with distracted driving because an autonomous vehicle is never distracted,” Matute told the Times.


 

$7.5 Million Federal Grant to Establish Mobility Center of Excellence at UCLA

The Federal Highway Administration, an agency within the U.S. Department of Transportation, has awarded a five-year, $7.5 million grant to establish the Center of Excellence on New Mobility and Automated Vehicles. The award will support research on the impacts of new mobility technologies on the evolving transportation system when deployed at scale. “Digital connectivity, automation and electrification have dramatically changed the way we transport, both in terms of how people travel and how goods are delivered,” said Jiaqi Ma, who will direct the new center. “We will study the impacts of these new technologies and how they can be better leveraged to improve equitable access to transportation and job participation.” Ma is faculty associate director of the UCLA Institute of Transportation Studies, where he leads the New Mobility program area. He is also an associate professor of civil and environmental engineering at the UCLA Samueli School of Engineering, where the new center will be based. Scheduled to launch in November, the Mobility Center of Excellence, as it will be informally known, will assess the anticipated long-term impact of new mobility technologies and services on land use, real estate and urban design; transportation system optimization including resilience, security and reliability; equitable access to mobility and job participation; and the cost-effective allocation of public resources. The center will include researchers from UCLA Samueli, UCLA Luskin School of Public Affairs and UCLA Fielding School of Public Health, along with other universities and government and nonprofit groups.

Report Finds Equity Gaps in L.A. Tech Sector

A new study led by UCLA Luskin Public Policy faculty member Jasmine Hill analyzes the diversity of 2022 venture capital investments in Greater Los Angeles. Released today, the report assesses investments made by 75 venture capital firms that are members of the PledgeLA initiative, which prioritizes equitable access to capital. Hill’s research team determined that less than one-third of the firms’ investments in 2022 went to companies led by women, Black or Latino founders, and these companies received only 4.6% ($6.4 billion) of the $139 billion invested. However, venture capital firms led by underrepresented minorities and those with a diversity thesis were almost twice as likely to back Latino and women founders and four times more likely to invest in Black founders. “Los Angeles has long surpassed the portfolio diversity typical of venture capital on the national level,” Hill said, “but there is a considerable journey ahead before PledgeLA firms reflect the region’s diversity.” The research team, which used a cross-section of data to create a holistic view of the Los Angeles tech ecosystem, included master of public policy student Sydney Smanpongse and public affairs major June Paniouchkine from the Luskin School and UCLA master of economics student Joleen Chiu. The report was commissioned by PledgeLA, launched by the Annenberg Foundation and the Office of the Mayor of Los Angeles to measurably increase diversity, equity and community engagement in the tech sector. In June, PledgeLA announced a new regional goal called “50 in 5,” which seeks to drive 50% of all venture investments to companies led by women, Black and Latino founders by 2028.

Circumvention of Censorship in China Has Increased During COVID-19 Pandemic People who broke through firewalls to seek health information also gained access to long-banned political content, study finds

By Mary Braswell

A study co-authored by Zachary Steinert-Threlkeld of the UCLA Luskin School of Public Affairs shows that more people in China circumvented censorship restrictions during the COVID-19 pandemic, opening a gateway to a trove of sensitive and long-hidden information.

Published today in the Proceedings of the National Academy of Sciences, the research identifies a spike in China-based activity on Twitter and Wikipedia, two platforms long banned by the government in Beijing.

The authors analyzed changes in the number of followers of popular accounts and traffic to certain Wikipedia pages to determine that, in addition to seeking news and information about the pandemic, users found sensitive information about China’s politics, history and human rights record.

During a crisis, the search for information increases under any form of governance, but leaders who use censorship as a tool to suppress dissent face heightened risks, said Steinert-Threlkeld, an assistant professor of public policy.

In China, the search for COVID-19-related information motivated individuals to find ways to skirt government-imposed regulations and technologies that block internet use. As a result, they gained access to censored material that government leaders perceive as damaging, he said.

“If I were one of those leaders I would find this alarming because it’s something that I can’t control.”

Researchers used Twitter to examine a sample of Chinese-language accounts whose self-reported locations are in mainland China, as well as an app-tracking service. They identified several trends, including:

  • an uptick in the number of people accessing technologies that would enable them to jump the Great Firewall, China’s network of restrictions on internet access;
  • Facebook becoming the 250th most downloaded app in China, up from the 600th, and Twitter becoming the 200th most downloaded app, up from the 575th, according to estimates;
  • a 10% long-term increase in the number of accounts from China using Twitter;
  • a greater than expected growth in followers — compared to users in Hong Kong, which was not under lockdown at the time — for accounts that tweet in Chinese, including international news agencies (31%), citizen journalists (42%), activists (28%) and pornography feeds that are generally banned in China (8%); and
  • increased viewership of Chinese-language Wikipedia pages on sensitive topics such as artist-activist Ai Weiwei and the 1989 Tiananmen Square protests.

The authors also uncovered nuances in Twitter usage. Their analysis of the content of the tweets alone suggested no effect — positive or negative — of the COVID-19 crisis. Digging deeper, however, they found that users who post only innocuous, nonpolitical tweets might still follow foreign news media, pro-democracy activists from Hong Kong or Taiwan, Chinese citizen-journalists or other banned Twitter accounts.

“As far as we can tell, the Chinese government has been relying on what people say to monitor the population,” Steinert-Threlkeld said. “But we show in this paper that people also reveal their sentiments by who they follow.”

The paper’s other authors are Keng-Chi Chang and Margaret E. Roberts of UC San Diego and William R. Hobbs of Cornell University.

The researchers note in the paper that Beijing’s crackdown on citizens who comment on banned platforms has become increasingly repressive over the last several years.

“While the results here do not link the COVID-19 crisis gateway effect to the political fortunes of the Chinese government, they do suggest that a country with a highly censored environment sees distinctive and wide-ranging increases in information access during crisis,” they conclude.

Matute on Democratizing Parking Data and Access

Juan Matute, deputy director of the UCLA Institute of Transportation Studies, was featured in a Dot.LA article about taking advantage of Los Angeles’ hidden parking spaces. According to Matute, the most straightforward way to cut down on congestion is by ensuring fewer cars are on the road in the first place. Still, new apps such as Metropolis can play an important role in “eliminating some of the most obvious and wasteful impracticalities associated with parking.” Even in dense areas like downtown Los Angeles, where a parking spot seems impossible to locate, there is abundant parking concealed in parking garages. The Metropolis app allows drivers to access parking facilities that are registered in the database without obtaining a ticket or paying at a booth; instead, the owner’s credit card is charged automatically. “These apps are addressing the issue where you only know about parking you can see,” Matute said.


Holloway Calls for Safety Precautions on LGBTQ Dating Apps

Professor of Social Welfare Ian Holloway spoke to Insider about the importance of safety precautions to protect users of LGBTQ dating apps such as Grindr. These apps have proven to be useful platforms for people to connect with one another, especially during the pandemic, but some have safety risks. Holloway noted that apps like Grindr “could be taking further steps to protect users.” For example, he suggested stronger staffing to help review profiles and monitor reports of improper behavior. “There’s often very little vetting because of the sheer volume of guys using these apps,” Holloway explained. At the start of 2021, Grindr reported having over 13 million active users worldwide, with only 100 customer support and content moderation staffers. “There is not enough content moderation on these platforms,” Holloway said. “And there’s really nothing that I’ve seen that allows users to escalate a case where they can get to an actual person.”


Tilly Analyzes Restructuring of Best Buy

Urban Planning Chair Chris Tilly spoke to Retail Dive about the internal reorganization of Best Buy following a recent large wave of layoffs. The company has been struggling to compete against generalist stores, such as Walmart and Target, as well as Amazon. Over the last decade, Best Buy said it prized a “human-centric approach” focusing on the company’s front-line workers, but it recently cut many full-time employees in favor of part-time staff who are expected to be knowledgeable about all areas of the store. “It’s clear that the entire store-based consumer electronics industry has faced incredible pressure from online sales,” Tilly said. “The fact that Best Buy survived and bounced back is miraculous, when a lot of other companies were going down.” The pandemic made competition even tougher by shifting more things online. “If you’re just competing with online sales, what is the difference between Best Buy and Amazon?” Tilly asked.


Manville Skeptical About Flying Car Technology

Associate Professor of Urban Planning Michael Manville spoke to KCRW’s “Greater LA” about the future of traffic in Los Angeles and the prospect of flying cars as a solution. Mayor Eric Garcetti’s interest in flying cars resulted in the creation of the Urban Air Mobility Partnership, which aims to release low-noise, electric aircraft by 2023. However, Manville expressed skepticism about the logistics of this new technology. “It’s just the beauty of technology that doesn’t exist yet. … You can say anything about it, right? It’s, ‘Oh, yeah, it’s gonna be affordable, and we’re gonna have this many vehicles in seven years,’” Manville said. “It just doesn’t work that way.” Manville was also featured in another “Greater LA” episode focusing on the cinematic inspiration for flying cars, from “The Jetsons” to “Blade Runner.” “If someone says, ‘We want to have less congestion and make it easier to move around,’ flying cars are a silly way to accomplish that,” Manville said.
