What Comes Next for the Law of the Sea Treaty?

On April 15, 2024

In History, Law, Lecture, Oceans, Policy

More than 40 years since its signing, the United States still has not ratified an international agreement known as the “constitution of the oceans.” In a webinar held April 2, two of the world’s leading ocean diplomacy scholars met to discuss its history, challenges, and the U.S.’s potential role in the future.

The 1982 United Nations Convention on the Law of the Sea was truly revolutionary for its time. Unraveling against the backdrop of decades of conflict pertaining to maritime affairs, the significance of this conference and its attempts at negotiating a comprehensive legal framework cannot be understated. Key figures in this development include the members of the United Nations, coastal and landlocked states, the scientific community, environmental community, and developing nations. Yet, with the conclusion of this unifying conference, a singular question remained: What comes next?

This question is what David Balton, the executive director of the U.S. Artic Steering Committee, and David Freestone, a Professor at George Washington University and the Executive Secretary of the Sargasso Sea Commission, aimed to address in a webinar titled, “The UN Convention on the Law of the Sea at 40.” In this discussion a range of topics were discussed but the primary focus was providing viewers with a comprehensive understanding of the events of this convention and the way this history plays out in modern times.

The 1982 convention was one of multiple attempts at setting parameters and guidelines for maritime control. In 1958, the council met for the first time to discuss growing concerns regarding the need for a comprehensive legal framework regarding ocean governance. In this they brought multiple representatives worldwide to discuss the breadth of territorial waters, the rights of coastal states, freedom of navigation, and the exploitation of marine resources. This conversation laid the groundwork for future discussions. However, it was largely ineffective at generating a treaty as they were unable to reach a consensus on the breadth of territorial waters. This first conference is referred to as UNCLOS I.

Following 1958, in 1960 the members of the council and associated parties convened once again to discuss the issues brought forth by UNCLOS I. The purpose of this conference was to further discuss issues pertaining to the Law of the Sea and build a framework to begin ratification of a binding treaty to ensure that conflict regarding the sea diminishes greatly. This discussion was set in the context of the Cold War. This new setting complicated discussions as talks regarding the implementation of nuclear weapons under the deep seabed further elicited great debate and tensions. While the aim of this meeting was of course to reach a general agreement on these subjects, major differences between states and other parties prohibited UNCLOS II from producing said treaty.

UNCLOS III served as the breadwinner of this development, yet this is not to say that results were immediate. Negotiations for UNCLOS III were the longest of the three as they spanned from 1973 to 1982. UNCLOS II was particularly special due to its ability to produce revolutionary concepts such as archipelagic status and the establishment of the exclusive economic zone (EEZ), granting coastal states exclusive rights over fishing and economic resources within 200 miles of their shores. In addition, this led to the development of the International Seabed Authority and the International Tribunal for the Law of the Sea. Despite the limitations and unfinished agenda that preceded this, the treaty was officially ratified in 1994 at Montego Bay. The convention initially received 157 signatories and currently holds participation from 169 parties. Absent from this group are the United States, Turkey, and Venezuela. The convention was designed to work as a package deal and required nations to fully commit to the agreement or abstain entirely. For this reason, the United States retains a nonparty, observer status despite to their adherence to the rules and guidelines of the treaty.

After this explanation, Balton and Freestone addressed the big question: What comes next? As of right now, the United States is still not a signatory of this treaty. However, this is not to say that they are in violation of this treaty either. The United States participates in discussions and negotiations related to UNCLOS issues, both within the United Nations and through bilateral and multilateral engagements. In addition, the Navy still upholds international law in dealings concerning navigational rights. The one factor many claims prohibits the United States from signing is the possibility of their sovereignty being challenged by certain provisions within the treaty. In spite of this, many continue to push to change this reality, advocating for the United States to ratify this agreement.

The 1982 United Nations Convention on the Law of the Sea remains a pivotal moment in the history of international maritime governance. This Convention led to many insightful and necessary developments which will continue to set precedent for generations to come. While imperfect, the efforts put forth by many nations and third parties to ensure that it remains consistent with modern day times is very telling of the hopeful development of this treaty. Furthermore, while the future of U.S. involvement in the treaty is uncertain, the frameworks established by the three UNCLOS’ provide a solid foundation for addressing contemporary challenges and furthering international cooperation.

We Are Killing Birds. Solutions Exist. Research Can Help.

By Sophie Cox

On April 11, 2024

In Animals, Biology, Environment/Sustainability, Science Communication & Education

Look at the nearest window. What did you see first—the glass itself or what was on the other side? For birds, that distinction is a matter of life and death.

A dead red-eyed vireo above the entrance to the Brodhead Center at Duke. Every year, millions of birds die after colliding with windows. Buildings with lots of glass are particularly dangerous.

Every year, up to one billion birds die from hitting windows. Windows kill more birds than almost any other cause of human-related bird mortality, second only to feral and domestic cats. Both the transparency and reflectiveness of glass can confuse flying birds. They either don’t see the glass at all and try to fly through it, or they’re fooled by reflections of safe habitat or open sky. And at night, birds may be disoriented by lit-up buildings and end up hitting windows by mistake. In all cases, the result is usually the same. The majority of window collision victims die on impact. Even the survivors may die soon after from internal bleeding, concussions, broken bones, or other injuries.

Madison Chudzik, a biology Ph.D. student in the Lipshutz Lab at Duke, studies bird-window collisions and migrating birds. “Purely the fact that we’ve built buildings is killing those birds,” she says.

Every spring and fall, billions of birds in the United States alone migrate to breeding and wintering grounds. Many travel hundreds or thousands of miles. During peak migration, tens of thousands of birds may fly across Durham County in a single night. Not all of them make it.

Chudzik’s research focuses on nocturnal flight calls, which migrating birds use to communicate while they fly. Many window collision victims are nocturnal migrants lured to their deaths by windows and lights. Chudzik wants to know “how we can use nocturnal flight calls as an indicator to examine collision risks in species.”

Previous research, Chudzik says, has identified a strong correlation between the number of flight calls recorded on a given night and the overall migration intensity that night. “If sparrows have a high number of detections, there is likely a high number migrating through the area,” Chudzik explains. But some species call more than others, and there is “taxonomic bias in collision risk,” with some species that call more colliding less and vice versa. Chudzik is exploring this relationship in her research.

Unlike bird songs, nocturnal flight calls are very short. The different calls are described with technical terms like “zeep” and “seep.” Chudzik is part of a small but passionate community of people with the impressive ability to identify species by the minute differences between their flight calls. “It’s a whole other world of… language, basically,” Chudzik says.

Chudzik can identify a species not only by hearing its flight call but also by seeing its spectrogram, a visual representation of sound. This spectrogram, from a recording on Adler Planetarium, has flight calls from four species. The x-axis represents time, while the y-axis shows frequency. The brightness or intensity indicates amplitude.
Image from Chudzik.

She began studying nocturnal flight calls for research she did as an undergraduate, but her current project no longer needs to rely on talented humans to identify every individual call. A deep learning model called Nighthawk, trained on a wealth of meticulous flight call data, can identify calls from their spectrograms with 95% accuracy. It is free and accessible to anyone, and much of the data it’s been trained on comes from non-scientists, such as submissions from a Facebook community devoted to nocturnal flight calls. Chudzik estimates that perhaps a quarter of the people on that Facebook page are researchers. “The rest,” she says, “are people who somehow stumbled upon it and… fell in love with nocturnal flight calling.”

In addition to studying nocturnal flight calls, Chudzik’s research will investigate how topography, like Lake Michigan by Chicago, affects migration routes and behavior and how weather affects flight calls. Birds seem to communicate more during inclement weather, and bad weather sometimes triggers major collision events. Last fall in Chicago, collisions with a single building killed hundreds of migratory birds in one night.

Chudzik had a recorder on that building. It had turned off before the peak of the collision event, but the flight call recordings from that night are still staggering. In one 40-second clip, there were 300 flight calls identified. Normally, Chudzik says, she might expect a maximum of about seven in that time period.

Nights like these, with enormous numbers of migrants navigating the skies, can be especially deadly. Fortunately, solutions exist. The problem often lies in convincing people to use them. There are misconceptions that extreme changes are required to protect birds from window collisions, but simple solutions can make a huge difference. “We’re not telling you to tear down that building,” Chudzik says. “There are so many tools to stop this from happening that… the argument of ‘well, it’s too expensive, I don’t want to do it…’ is just thrown out the window.”

What can individuals and institutions do to prevent bird-window collisions?

Turn off lights at night.

For reasons not completely understood, birds flying at night are attracted to lit-up urban areas, and lights left on at night can become a death trap. Though window collisions are a year-round problem, migration nights can lead to high numbers of victims, and turning off non-essential lights can help significantly. One study on the same Chicago building where last year’s mass collision event occurred found that halving lighted windows during migration could reduce bird-window collisions by more than 50%.

Chudzik is struck by “the fact that this is such a big conservation issue, but it literally just takes a flip of a switch.” BirdCast and Audubon suggest taking actions like minimizing indoor and outdoor lights at night during spring and fall migration, keeping essential outdoor lights pointed down and adding motion sensors to reduce their use, and drawing blinds to help keep light from leaking out.

Use window decals and other bird-friendly glass treatments.

There are many products and DIY solutions intended to make windows safer for birds, like window decals, external screens, patterns of dots or lines, and strings hanging in front of a window at regular intervals. For window treatments to be most effective, they should be applied to the exterior of the glass, and any patterning should be no more than two inches apart vertically and horizontally. This helps protect even the smallest birds, like kinglets and hummingbirds.

It can be hard to see from a distance, but these windows on Duke’s Fitzpatrick Center have been retrofitted with tiny white dots, an effective strategy to reduce bird-window collisions.

A 2016 window collision study at Duke conducted by several scientists, including Duke Professor Nicolette Cagle, Ph.D., identified the Fitzpatrick Center as a window collision hotspot. As a result, Duke retrofitted some of the building’s most dangerous windows with bird-friendly dot patterning. Ongoing collision monitoring has revealed about a 70% reduction in collisions for that building since the dots were added.

One obstacle to widespread use of bird-friendly design practices and window treatments is concerns about aesthetics. But bird-friendly windows can be aesthetically pleasing, too, and “Dead birds hurt your aesthetic anyway.”

If nothing else, don’t clean your windows.

Bird-window collisions don’t just happen in cities and on university campuses. In fact, most fatal collisions involve houses and other buildings less than four stories tall. Window treatments like the dots on the Fitzpatrick building can be costly for homeowners, but anything you can put on the outside of a window will help.

“Don’t clean your windows,” Chudzik suggests—smudges may also help birds recognize the glass as a barrier.

Window collisions at Duke

The best thing Duke could do, Chudzik says, is to be open to treating more windows. Every spring, students in Cagle’s Wildlife Surveys class, which I am taking now, collect data on window collision victims found around several buildings on campus. Meanwhile, a citizen science iNaturalist project collects records of dead birds seen by anyone at campus. If you find a dead bird near a window at Duke, you can help by submitting it to the Bird-window collisions project on iNaturalist. Part of the goal is to identify window collision hotspots in order to advocate for more window treatments like the dots on the Fitzpatrick Center.

Spring migration is happening now. BirdCast’s modeling tools estimate that 260,000 birds crossed Durham County last night. They are all protected under the Migratory Bird Treaty Act. However, Chudzik says, “We haven’t thought to protect them while they’re actually migrating.” The law is intended to protect species that migrate, but “it’s not saying ‘while you are migrating you have more protections,’” Chudzik explains. Some have argued that it should, however, suggesting that the Migratory Bird Treaty Act should mandate safer windows to help protect migrants while they’re actually migrating.

“This whole world comes alive while we’re asleep, and… most people have no idea,” Chudzik says about nocturnal flight calls. She is shown here on Northwestern University, one of the Chicago buildings where she has placed recorders for her research.

We can’t protect every bird that passes overhead at night, but by making our buildings safer, we can all help more birds get one step closer to where they need to go.

Echoes of Liberty: Revisiting the Swatantra Party’s Vision for India’s Economy

By Noor Nazir

On April 4, 2024

In Economics, Lecture, Policy

If you’re looking to revisit the nuanced history of the Swatantra Party in post-colonial India, you’ve come to the right place! During Aditya Balasubramanian’s talk on his book, ‘Toward a Free Economy: Swatantra and Opposition Politics in Democratic India’, I embarked on a journey that not only took me back to South Asia’s economy but also helped me reflect on the broader implications of Balasubramanian’s vision for a free economy.

I grew up to have an interest in India’s economic history. Living in Pakistan, we (my household) always looked toward our neighboring country, India, to reflect on our own economic situation. The echoes of discussion on free economy versus socialist planning reverberated in the hallways of everywhere I turned to. The narrative of the Swatantra Party, as captured in the book and the talk, presents a fascinating counterpoint to the dominant economic narratives in post-colonial India, challenging us to ponder the possibilities of a different economic path.

Balasubramanian talked about the heart of Swatantra’s ideology: a profound belief in a nonsectarian, right-wing political stance, advocating for an unfettered private economy and a decentralized economic system. The party’s anti-communism stance wasn’t merely ideological but a practical caution against nationalization. This reminds me of discussions with my grandmother, who, amidst the economic challenges of her time, often lamented the lost opportunities for economic liberalization that Swatantra championed.

Balasubramanian went on to explain the narrative of the Indian libertarian, Ranchhoddas Bhuvan Lotwala, and his transformation of a flower shop into a machine-operated flour mill encapsulates the spirit of economic innovation and entrepreneurship that Swatantra celebrated. This story, emblematic of the broader push for modernization and the embrace of new technologies, serves as a reminder of the countless small businesses across India that continue to innovate and adapt in the face of changing economic landscapes. These small businesses play a bigger role than we think, and the economy of the government can aid in transforming their potential. Swatantra and its stories serve as proof for that.

He concluded the talk by pointing out three things that need our attention::

1) Exploring how a free-market economy can work alongside federal government policies.

2) Addressing how special interests have influenced policies in a way that ignores regional concerns, particularly noting the removal of corporate taxes.

3) Emphasizing the importance of limiting authoritarian tendencies to ensure a balanced and democratic governance system.

The Swatantra Party’s story is a reminder of the enduring power of ideas and the impact they can have on the economic and political fabric of a nation: it is a story that must never be forgotten. Afterall, there’s too much to learn from it.

The Invisible Role of Women in Africa’s Liberation Movements

In Humanities, Lecture

“Claims to knowledge are claims to power”

This phrase succinctly encapsulates Dr. Rama Salla Dieng’s talk on the intricate relationship between information and the patriarchy that exists, and has existed, in our society.

As a Pan-Africanist Feminist scholar-activist, Dr. Dieng’s research mainly encompasses the Anti-Colonial Feminist Solidarity in West Africa. She delved into the Yewwu Yewwi, the first feminist movement in Senegal. She further highlighted the main aims of the women’s liberation movement; to cultivate and maintain solidarity between the members, to stand in solidarity with all Senegalese women, and to show support with all other victims of apartheid.

The focus of this talk was to shed light on movements in Africa that have supported women. She accentuated the importance of mid-wifes, and women who oversaw child-care, cooked, and worked on the fields. They were leading, not from the front but from the back. According to her, the purpose of the liberation movement is to not only celebrate the visible, but also acknowledge the invisible – the true backbone of those who lifted others during the apartheid.

“Can rural African women be heard alongside Aimé and Senghor as also articulating prescient visions of liberation in the 20th century? Can M’ballia Camara’s death at the hands of a canton chief, her pregnant body slashed open by his saber in a dispute over local taxes for the colonial administration, speak across time and archival silences? Can it speak into a historical canon that is only now beginning to acknowledge black women as midwives who help to birth anticolonial movements and bear witness also to the leadership in these movements?” Dieng used Joseph-Gabriel’s poignant reflections to emphasize the pivotal yet overlooked contributions of rural African women in shaping liberation narratives, highlighting the necessity of integrating their voices into our historical understanding.

Dieng’s exploration into the Yewwu Yewwi movement and her invocation of historical accounts like M’ballia Camara’s tragic fate highlight a crucial message: the narratives of rural African women are integral to understanding the full spectrum of liberation efforts. By recognizing the gendered labor that has sustained communities through apartheid and beyond is not only existent but invaluable, we can begin to dismantle the structures of patriarchy that have long marginalized these vital contributions.

M’balia Camara: Guinean independence activist

As I reflect on the significance of these revelations, I am reminded that the path to true liberation is paved with the stories of those who have been overlooked.

Let us commit to making these voices heard, ensuring their rightful place in the annals of history and in the continuing struggle for equality and justice!

Students Offer Their Voices of Change to Climate Commitment

By Gabrielle Douglas

In Climate/Global Change, Science Communication & Education, Students

In a society where it seems like the power to create meaningful change on climate concerns is concentrated in the hands of few, witnessing the youth attempt to counter this dynamic is always inspiring.

Last week, members of Duke University’s Climate and Sustainability Office convened with students for a town hall meeting to discuss current progress, areas for improvement, and aspirations for the future. During this meeting, great emphasis was placed on the opinions and perspectives of students, as the leaders of the Duke climate commitment recognized the importance of their voices within this process.

The meeting began with two thought-provoking questions by Toddi Steelman, Vice President and Vice Provost for Climate and Sustainability, and Tavey Capps, Executive Director of Climate and Sustainability and Sustainable Duke: “What is one word to describe your feelings towards climate change, and what energizes you about climate change?”

These two questions immediately brought the room to life as students began to express their climate anxiety, fears, and frustrations, alongside the ways in which they hoped to one day see change. This passionate discussion set the stage for a deep dive into the objectives and goals of Duke’s Climate Commitment.

*L to R: Toddi Steelman and Tavey Capps*

The Climate Commitment is a university-wide effort aimed at creating initiatives to correct our current climate crisis by creating a sustainable environment for all.

Within the commitment, there are five areas of focus: Research, Education, External Engagement, Operations, and Community Connections. The research sector is focused on connecting Duke’s schools across the board for interdisciplinary research. Education is geared towards ensuring learning occurs in and beyond the classroom. External Engagement focuses on informing policy and decision makers alongside engaging community members within this mission. Operations studies the food, water, waste, energy, and carbon supply chain on campus. Lastly, Community Connections asks: how do we authentically engage with the community and partners alike?

This commitment serves as a broad scale invitation for everyone to get involved, and Duke students did not hesitate to take advantage of this invitation. The town hall was organized through breakout rooms for the students to collectively share ideas.

The first breakout room was focused on the idea of communication. In this, students discussed the ways that they felt the commitment could best reach their peers on campus. Some proposed utilizing the popular social media platform, TikTok by creating short eye-catching videos. Others discussed using professors, posters, and BC Plaza to ensure engagement. Most agreed that email listservs and newsletters also held some merit in getting their classmate’s attention.

Above all, students came to the consensus that informing the student body would be one of the most important missions of the Climate Commitment.

Following the communication session, I attended the research breakout room led by Blake Tedder from the Office of Sustainability and formerly the Director of Engagement at the Duke Forest. He asked again about the most pressing climate issue. From this, many students delved into issues surrounding biodiversity financing, carbon offsetting, access to clean water, and the ways climate change disproportionately affects marginalized communities.

*Blake Tedder leading the Research Breakout Room.*

Conversation about these concerns quickly bled into issues surrounding the larger prospect of interdisciplinary studies. Many students felt that this was best done through Duke’s RESILE initiative (Risk Science for Climate Resilience), Bass Connections, and even greater connection between Duke’s main campus and its Kunshan Campus.

The final room I attended was geared towards making the fight against climate change one that is inclusive and diverse. This talk was coordinated by Jason Elliot from Sustainable Duke.

The question that guided the discussion was: “How can we ensure our goals do not come at the expense of the community?” To this, students proposed a range of ideas. Chief among these were becoming more in tune with the needs of the community and finding ways to actively attend local farms, and other places in need.

*Jason Elliot leading the Justice, Diversity, and Equity Inclusion Breakout Room.*

In addition, many suggested diversifying speakers to ensure representation and voices from all parts of the community. Some students even narrowed in on engagement within our own campus, suggesting greater collaboration among groups such as the Climate Coalition, Keep Durham Beautiful, and Alpha Phi Omega to achieve these goals.

This town hall was simply one of many future engagements expected from Duke’s Climate Commitment in the coming years. While there is still much more work to be done, the diligent efforts of students and faculty alike make the future look promising in the fight against Climate Change.

To get a fuller picture of a forest, sometimes research requires a team effort

For some people, the word “rainforest” conjures up vague notions of teeming jungles. But Camille DeSisto sees something more specific: a complex interdependent web.

For the past few years, the Duke graduate student has been part of a community-driven study exploring the relationships between people, plants and lemurs in a rainforest in northern Madagascar, where the health of one species depends on the health of others.

Many lemurs, for example, eat the fruits of forest trees and deposit their seeds far and wide in their droppings, thus helping the plants spread. People, in turn, depend on the plants for things like food, shelter and medicines.

But increasingly, deforestation and other disturbances are throwing these interactions out of whack.

DeSisto and her colleagues have been working in a 750,000-acre forest corridor in northeast Madagascar known as the COMATSA that connects two national parks.

The area supports over 200 tree species and nine species of lemurs, and is home to numerous communities of people.

“People live together with nature in this landscape,” said DeSisto, who is working toward her Ph.D. in ecology at the Nicholas School of the Environment.

But logging, hunting and other stressors such as poverty and food insecurity have taken their toll.

Over the last quarter century, the area has lost 14% of its forests, mostly to make way for vanilla and rice.

This loss of wild habitats risks setting off a series of changes. Fewer trees also means fewer fruit-eating lemurs, which could create a feedback loop in which the trees that remain have fewer opportunities to replace themselves and sprout up elsewhere — a critical ability if trees are going to track climate change.

DeSisto and her colleagues are trying to better understand this web of connections as part of a larger effort to maximize forest resilience into an uncertain future.

To do this work, she relies on a network of a different sort.

The research requires dozens of students and researchers from universities in Madagascar and the U.S., not to mention local botanists and lemur experts, the local forest management association, and consultants and guides from nearby national parks, all working together across time zones, cultures and languages.

Together, they’ve found that scientific approaches such as fecal sampling or transect surveys can only identify so much of nature’s interconnected web.

Many lemurs are small, and only active at night or during certain times of year, which can make them hard to spot — especially for researchers who may only be on the ground for a limited time.

To fill the gaps, they’re also conducting interviews with local community members who have accumulated knowledge from a lifetime of living on the land, such as which lemurs like to munch on certain plants, what parts they prefer, and whether people rely on them for food or other uses.

By integrating different kinds of skills and expertise, the team has been able to map hidden connections between species that more traditional scientific methods miss.

For example, learning from the expertise of local community members helped them understand that forest patches that are regenerating after clear-cutting attract nocturnal lemurs that may — depending on which fruits they like to eat — promote the forest’s regrowth.

Research collaborations aren’t unusual in science. But DeSisto says that building collaborations with colleagues more than 9,000 miles away from where she lives poses unique challenges.

Just getting to her field site involves four flights, several bumpy car rides, climbing steep trails and crossing slippery logs.

“Language barriers are definitely a challenge too,” DeSisto said.

She’s been studying Malagasy for seven years, but the language’s 18 dialects can make it hard to follow every joke her colleagues tell around the campfire.

To keep her language skills sharp she goes to weekly tutoring sessions when she’s back in the U.S., and she even helped start the first formal class on the language for Duke students.

“I like to think of it as language opportunities, not just language barriers,” DeSisto said.”

“Certain topics I can talk about with much more ease than others,” she added. “But I think making efforts to learn the language is really important.”

When they can’t have face-to-face meetings the team checks in remotely, using videoconferencing and instant messaging to agree on each step of the research pipeline, from coming up with goals and questions and collecting data to publishing their findings.

“That’s hard to navigate when we’re so far away,” DeSisto said. But, she adds, the teamwork and knowledge sharing make it worth it. “It’s the best part of research.”

This research was supported by Duke Bass Connections (“Biocultural Sustainability in Madagascar,” co-led by James Herrera), Duke Global, The Explorers Club, Primate Conservation, Inc., Phipps Conservatory and Botanical Gardens, and the Garden Club of America.

Big Bets on Humanity: How Rajiv Shah’s Audacity is Winning the Fight Against Pandemics

By Noor Nazir

On March 30, 2024

In Global Health, Lecture

If your community relied on COVID-19 rapid tests to reopen safely during the first year of the pandemic, there’s a good chance Rajiv Shah had something to do with it. Not just for his ambition but also for his audacity to transform the nature of our response to pandemics: Rajiv Shah, the president of the Rockefeller Foundation, played a crucial role in scaling up diagnostic testing for COVID-19.

He’s also the man who tackled Ebola with the Obama Administration. Back then, Shah and his team embarked on a “big bet” to deploy 2,500 troops to fight the disease, not on the battlefield, but on the frontlines of human health. Much like the name of his 2023 book “Big Bets,” he embarked on a journey to change the world.

In a Jan. 31 talk hosted by the Duke Global Health Institute, Shah discussed his “big bet mindset” when it comes to tackling public health challenges.

Bet #1 Diagnostic Testing at Scale

For starters, what’s a big bet?

“It’s a big bet you take on the community to help young people get opportunities. Often, when we think of charitable endeavors, we imagine that doing a little bit is beneficial because it makes us feel good. In contrast, a big endeavor means taking on something significant and engaging in the hard work necessary. It’s about going beyond just doing the best we can; this isn’t merely a charitable endeavor, it’s a strategic approach to ensure national security.” Shah explained.

Keeping true to his word, the goal was clear: administer 30 million tests per week to preempt the need for lockdowns and enable a safer, faster return to normalcy. This was not just a health initiative; it was a socio-economic strategy aimed at averting total disaster. He took a big bet, and the numbers spoke for themselves. The Rockefeller Foundation played a pivotal role in assisting schools with their reopening strategies during the pandemic. This support included the establishment of collaborative networks, the development of resources and guidelines, and the provision of expert recommendations. Now do you get why this man probably saved your life? It’s because he did!

Bet #2 A Memo for Bill Gates

It wasn’t all that easy for him though. He had his haters (don’t we all?). Perhaps the difference was, his hater was Bill Gates. But he successfully proved Gates wrong too. Thankfully, Gates and Shah are more like besties than anything now. Despite the initial dismissal of his ideas as “the stupidest thing,” Shah’s persistence and innovative thinking paved the way for a groundbreaking bond structure to fund vaccinations, ultimately saving millions of children’s lives. Shah and Gates – two greats in one room – inevitability led to the production of something good: The Vaccine Alliance. This meeting set the stage for a three-year roadmap focused on a bond structure to fund vaccinations. This initiative ultimately contributed to saving 16 million children’s lives.

The Final Bet: The Power of Experimentation.

I’ll be honest, I was intimidated walking into this room. I was in my Duke hoodie, not expecting fancy foods, and coat checks (good news: this meant they recorded his speech and uploaded it on YouTube. Check it out!).

At the heart of Shah’s philosophy is a belief in the power of experimentation and innovation. His call to “keep experimenting” embodies the spirit of resilience and creativity that is essential for tackling the world’s most daunting health challenges. Being amidst well-suited individuals while donned in a hoodie wasn’t an experiment in the scientific sense, but it was an experience that highlighted the contrast between expectations and reality, comfort zones and the unfamiliar. It served as a metaphor for the broader experiments we’re all a part of—those that push us beyond our boundaries, challenge our preconceptions, and ultimately lead to growth.

His book was called ‘Big Bets’ because the editors thought it was catchy. They were right. But this title doesn’t just grab our attention—it invites us into a world where daring to dream big and taking calculated risks can lead to monumental changes in public health and beyond.

“Biodiversity Is Essential, and It’s Not a Nice-to-Have”

“I have been interested in storytelling and the environment since my earliest memories,” says Ashley Hillard, a documentary filmmaker with an interest in wildlife management and conservation practices in the United States.

Hillard has a background in film, largely with production companies, talent agencies, and independent projects on the side, but she later shifted into climate tech recruitment. Now she is pursuing an environmental leadership Masters in Environmental Management degree at Duke while working on documentary projects. She is also a Communications Assistant Intern in the Duke Environmental Law and Policy Clinic.

She has been working on a film called “Coexistence,” a documentary that spotlights North American species and wildlife management practices. Hillard got the idea for the project when she noticed that U.S.-based researchers often choose to study species in other countries, perhaps “because it’s easier to go over and say ‘Why don’t you try this?’ rather than having to deal with issues in your backyard.”

“We need to pay attention to our own backyards,” Hillard emphasizes. “The hope,” she says, is “more laws and policies and values change along with behaviors as we become more informed and more aware.” She also believes that “local efforts can usually go further.” Part of her goal in creating films about conservation is to help viewers realize that “individuals can be part of change.” Films and other forms of storytelling can inform people about specific species and conservation efforts, but Hillard hopes her work can help shift perspectives more broadly as well. Effective conservation is often “a social attitudes and values issue,” Hillard says. “There needs to be a shift in how we view the environment.”

Shifting baseline syndrome is the idea that people’s expectations of how nature should look reflect their own experiences rather than an accurate picture of the natural state of landscapes, flora, fauna, and wildlife abundance. Our understanding of what nature “normally” looks like changes over generations and is skewed by the societies and time periods we inhabit. The more we damage our environments, the less we collectively remember what they looked like before—and the less motivated we may be to restore them to a condition most of us can’t remember.

When humans and wildlife come into conflict, our perceptions of how nature “should” be can matter tremendously. Gray wolves were recently delisted from the Endangered Species list, then re-listed in most places—both were controversial decisions—but their numbers are far lower than they were historically. Still, some think there are too many wolves. In the Western U.S., gray wolf conservation efforts often clash with the desires of ranchers and and hunters, who may view higher wolf populations as a threat to livestock or game animals like deer and elk. But some of these hunters and ranchers, Hillard says, “are real conservationists doing amazing work,” and she thinks they should get more attention.

While creating the film, Hillard has tried to capture the complexities of wildlife conservation. It’s not as simple as “They’re bad, they’re good, and this is how we solve it,” Hillard says.

There are different ideas about how conservation efforts should be conducted and which animals should be protected in the first place. The dominant approach to wildlife management in the U.S., Hillard says, is rooted in the idea that there are “good” species that people can use and “bad” species that people don’t like to live with, such as wolves and other predators. “This perspective,” she says, “came over with colonists.” She mentions Little Red Riding Hood and the Big Bad Wolf; the stories we tell about animals can reflect societal attitudes toward them. Many indigenous peoples, meanwhile, have traditionally viewed all species as kin. This “cultural aspect” affects people’s willingness to coexist with species like wolves, which in turn affects our conservation practices.

In this country, very few people are killed by wildlife—about 700 annually, according to one review that counted deaths from bites, wildlife-vehicle collisions, and zoonotic diseases. Car accidents, on the other hand, are more than 60 times more deadly, killing about 43,000 people in the U.S. per year. “We have a certain acceptance of how we die,” Hillard says. “There are a number of things that kill people with much higher percentages [than deaths from wildlife] that we… accept as day-to-day,” but we don’t tend to hear calls to eliminate cars from society, while an animal that harms a human is often given a death sentence. Hillard thinks media in general should be more careful about how they share stories about wildlife, especially negative encounters. If stories focus only on rare but tragic incidents, it can distort perceptions of species and “feed into that doom loop.”

Films, Hillard says, can inspire people “to look at things differently and see things from different perspectives.” Storytelling is also a way of communicating scientific information and encouraging action. Hillard feels that some stories about environmental issues are told in a one-sided, black-and-white way, but the nuances of these problems are important. “Finding those complexities and working through them… and then trying to craft stories around that to share with the public so they can make more informed decisions” is part of the goal of Hillard’s films.

“Coexistence” focuses on well-known, often controversial species like red wolves and mountain lions. “Familiarity and awareness of a species can contribute to interest in protecting them,” Hillard says. Such species are sometimes referred to as charismatic megafauna and can be viewed as ambassadors for conservation or umbrella species whose protection helps other wildlife as well. But Hillard has concerns about the term charismatic megafauna. “It diminishes a species’s value and reduces them to ‘cute’ so you no longer see them as an intrinsic part of an ecosystem,” she says. She believes it’s important to emphasize protection of entire ecosystems, not just specific species within them.

Hillard hopes that her films inspire more awareness of and interest in environmental issues. “There’s a lot of pressure to get it right,” she says. And storytelling can have its own issues when it comes to presenting accurate information. “Information can be left out or shaped in a way to make it more compelling,” Hillard acknowledges. She feels that many wildlife films focus first on scenery and animals, then discuss conservation issues at the end. But “Coexistence” is “very much focused on the issues.” It is expected to be released by early 2025.

“I strive to tell impactful stories in creative ways that are more upbeat in tone,” Hillard says. She believes it’s important for people to be aware of the challenges facing wildlife, but she also wants to inspire hope and the belief that individual actions can matter. “To feel powerless can make you feel hopeless, and there is a lot to be hopeful for,” she says. “But there needs to be a shift in how we view the environment.”

One major problem she sees is our consumerist, materialistic society. “We’re kind of consuming ourselves off the planet,” Hillard says. “How do you change behaviors within a society that’s so hyper-consumptive?”

Films and other forms of storytelling can make scientific information more accessible. “Communicating is that bridge to getting people to care, to understand it, to learn about it,” Hillard says. “Without communication, science studies and research may be siloed in academia.” When we lack accurate and accessible information, we may rely on “‘I heard someone say something about that thing’” rather than science to inform our understanding of issues.

Along with providing accurate information, Hillard wants to encourage “a view of mutualism with other species” and raise questions like “How can we be better neighbors to nonhuman species?”

Ultimately, she wants viewers to recognize that “biodiversity is essential, and it’s not a nice-to-have.”

Casting roles, casting votes: Lessons from Sesame Street on media representation and voting

By Emily Zou

In Behavior/Psychology, Policy

La la la la, la la la la, Elmo’s world. La la la la, la la la la, Elmo’s world!

After listening to Dr. Claire Duquennois, it’s come to my attention that we might actually be living in Elmo’s world. On February 29, Duquennois, an assistant professor in the Department of Economics at the University of Pittsburgh, spoke at the Sanford School of Public Policy about her research on the impact of “Sesame Street” on voter turnout and behavior. As the first of a series of papers on child media representation, Duquennois and her co-author Jiangnan Zeng examined the impact of the highly popular television show on voters born in the 1960s.

For those who didn’t have “Sesame Street” as a cornerstone of their childhood, the show first aired in November 1969, and quickly attracted a large audience of young children from 2-5 years old. The show was unique in its academic and socio-emotional curriculum, as well as in its diverse and integrated cast. Duquennois described the show as having two intents: the first was to create academic curriculum for preschool age children. But the second, more implicit goal was to improve children’s self image, increase their racial tolerance, and highlight the importance of different perspectives, cooperation, and fairness. This is exhibited by the amount of documentation from the creation of the show, as well as the consultation of psychiatrists like Dr. Chester Pierce, who was an expert in the consequences of racism and television’s impact on the portrayal of minorities.

Whereas other shows like “Mister Rogers’ Neighborhood” featured a more white and suburban cast and setting, “Sesame Street” aimed to relate to kids in more urban or low income areas. For example, both the adult and adolescent cast featured numerous people of color, and the show’s set was reminiscent of Harlem brownstones. The show also brought on numerous diverse guest stars, many of which were important figures in the Civil Rights movement. For many children living in white-dominated suburbs at the time, “Sesame Street” was their first introduction to people of different cultural backgrounds. This “hidden agenda” did not go unnoticed by more conservative governments. For example, the Mississippi commission for education TV vetoed the airing of “Sesame Street” due to the messaging of integration and diversity, although this decision was later overturned due to popular support for the show. Duquennois and Zeng wanted to know: Can child media reduce prejudice in the long-run, impacting voter preferences and behaviors in adulthood?

There had already been a lot of research on mass media in terms of short-term voting outcomes, Duquennois said. In particular, she spoke about research on the news and mass media creating a negative impact on racial and ethnic tensions. However, there was a lack of research on both child media and its impact on later life voting, as well as media’s ability to reduce biases in the majority group. In particular, Duquennois frequently referenced a paper by Melissa S. Kearney and Phillip B. Levine titled “Early Childhood Education by Television: Lessons from Sesame Street.” Duquennois also spoke on the previous research done on contact theory, which has proven that interactions with other groups can help to reduce biases. For example, research done on random college roommates has found that introducing college-age students to people from differing cultural backgrounds has a positive impact on reducing prejudice.

To any readers still waiting to hear the connection, here it is. Duquennois used a difference in difference model with four different segments (really, a scale of low to high coverage, but she simplified for our sake). The treatment group is identified as children younger than six (“Sesame Street’s” target audience, as well as kids who would be home the majority of the day instead of at school) and with high coverage. This methodology is primarily based on Kearney and Levine’s 2019 study mentioned earlier. Since it’s impossible to tell which children were actually watching “Sesame Street,” Kearney and Levine relied on the statistic that nearly 50% of children were watching the show if it was available to them. They also controlled for general patterns in a particular cohort in that particular state like migration and attenuation bias.

In terms of getting voting reports, the study used election year responses from 2006-2020 on the Cooperative Congressional Election Study (CCES) as well as Implicit Association Test (IAT) scores. Specifically, the report used data in major party ballots for US House elections.

In terms of results, Duquennois broke elections into various different demographic compositions. This included elections between two white men, a Republican white man and Democrat woman of color, vice versa and et cetera.

The results were quite interesting. In the case of electoral participation, an increase in coverage by one standard deviation (20 ppts) increased the treated cohort’s voter turnout by 2.8 ppts (4.4%). Voter registration increased by 1.8 ppts (2.4%), and treated cohorts were more likely to know whether they were registered or not.

Additionally, those with more television coverage in their childhood later on expressed increased political knowledge, including more interest in public affairs, better recognition of elected officials’ names, and increased engagement for marginal voters. There was also increased identification with a party and political ideology. However, there were null effects on more costly forms of political engagement like protesting or primary turnout rates.

The most interesting part to me, however, is the impact on voter preferences. Duquennois found that former watchers of “Sesame Street” are more likely to vote for minority and female candidates, regardless of political party.

Even more interesting, the decreased race and gender bias in voting patterns does not translate to policy views. There’s evidence that “Sesame Street” viewers both support gay marriage and restrictive immigration policies, which are often seen as opposing political views. That said, what is consistent is that those in the treated cohort were more likely to have an opinion, regardless of what the opinion actually is.

Moreover, it appears that the hidden messaging of “Sesame Street” was effective in decreasing bias. According to the IAT score results, one standard deviation increase in television coverage reduced the race IAT scores of white subjects by 0.013 standard deviations. However, it had null effects on non-white respondents. There was no evidence of selection bias of taking the race IAT in treatment versus non-treatment groups. As for the gender-career IAT test scores, there was no clear change on bias results, but there was evidence of a selection bias with the treated cohort more likely to take the gender-career IAT.

Duquennois concluded her presentation with a few final takeaways: “Preschool age exposure to child media portraying an inclusive, egalitarian and diverse America reduced prejudice in the long run, with consequential implications for voter preferences.”

Acknowledging America’s Unspoken Caste System

By Skylar Hughes

On March 7, 2024

In Behavior/Psychology, Lecture, Policy

Pulitzer Prize-winning author Isabel Wilkerson took the Page Auditorium stage on February 22 to discuss her most recent book, “Caste,” and its implications for modern-day America. Co-hosted by the Sanford School of Public Policy and the Mary Lou Williams Center for Black Culture, the event featured a lecture and Q&A section.

A caste system is an artificial construction, a fixed and embedded ranking of human value that sets the presumed supremacy of one group against the presumed inferiority of other groups.”
Isabel Wilkerson

When Wilkerson first published “Caste: The Origin of Our Discontents,” it spent 55 weeks on the U.S. best sellers list. Barack Obama put it in his 2020 reading list, and Oprah Winfrey sent the book to Fortune 500 CEOs around the world. Since then, it has sold over 1.56 million copies and has become a #1 New York Times best seller.

In other words: “Caste” is the Beyoncé of books.

Wilkerson began by reminding the audience of the recentness of our country’s progress. “In recent times it’s not been unusual to hear people say something along the lines of ‘I don’t recognize my country,’ Wilkerson began. “And whenever I hear that I’m reminded that tragically not enough of us have had the chance to know our country’s true and full history.” She described the U.S. as a patient with a preexisting health condition, asserting that America has been plagued by racism since its inception. Like a chronic disease, these roots continuously persist and flare up.

For context, the United States is 247 years old. A full 89 of those years were spent in slavery and 99 were spent in the Jim Crow era. For 227 years, race was considered an innate, factual construct (until the completion of the Human Genome Project in 2003). Racial injustice isn’t a period of history in this country, it is this country’s history.

Wilkerson furthered her point by detailing the dehumanizing customs of the Jim Crow caste system in the South. “You could go to jail if you were caught playing checkers with a person of a different race,” Wilkerson said. “That means that someone had to have seen a Black person and a white person in some town square… And they felt that the entire foundation of southern civilization was in peril and took the time to write that down as a law.” Before the late 20th century, there was even a separate Black and White Bible to take an oath in court. “That means that the very word of God was segregated in the Jim Crow South,” Wilkerson said.

She described this system of racial oppression as an “arbitrary, artificial, graded ranking of human value” – in other words, a caste system. She highlighted how race was weaponized by early colonists to determine “who would be slave or free, who would have rights and no rights.”

This caste system wasn’t just a “sad, dark chapter,” Wilkerson said. It’s “the foundation of the country’s political, social, and economic order.”

For 6 million Black southerners, the caste system became so suffocating that migrating across the country (a movement called The Great Migration), seemed like the only path to freedom. “No other group of Americans has had to act like immigrants in order to be recognized as citizens,” Wilkerson said. “So this great migration was not a move. It was not about moving. It was a defection. A seeking of political asylum within the borders of one’s own country.”

But the U.S. caste system extends far past slavery and Jim Crow. Take the vastly different police response to the January 6 Capitol riot compared to BLM protests during the summer of 2020. “We alive today are tasked with explaining to succeeding generations how…a rioter could deliver the Confederate flag farther than Robert E. Lee himself.” The United States has never adequately dealt with its racist history, which is why it keeps repeating itself.

In a powerful call to action, Wilkerson urged the audience to honor these histories and “teach the children so that we can end these divisions now with the next generation.” She shared the aspiration of novelist Richard Wright: “To transplant in alien soil…and perhaps just perhaps to bloom” in a more equitable world.
