Paper by Amirhosein Shabrang, Mehdi Pourpeikari Heris, and Travis Flohr: “We investigated the spatial shade patterns of trees and buildings on sidewalks and bike lanes in Cambridge, Massachusetts. We used Lidar data and 3D modeling to analyze the spatial and temporal shade distribution across the City. Our analysis shows significant shade variations throughout the City. Western city areas receive more shade from trees, and the eastern regions receive more shade from buildings. The City’s northern areas lack shade, but natural and built sources of shade can improve shade coverage integration. This study’s findings help identify shade coverage gaps, which have implications for urban planning and design for more heat-resilient cities…(More)”
Who Is Government?
Book edited by Michael Lewis: “The government is a vast, complex system that Americans pay for, rebel against, rely upon, dismiss, and celebrate. It’s also our shared resource for addressing the biggest problems of society. And it’s made up of people, mostly unrecognized and uncelebrated, doing work that can be deeply consequential and beneficial to everyone.
Michael Lewis invited his favorite writers, including Casey Cep, Dave Eggers, John Lanchester, Geraldine Brooks, Sarah Vowell, and W. Kamau Bell, to join him in finding someone doing an interesting job for the government and writing about them. The stories they found are unexpected, riveting, and inspiring, including a former coal miner devoted to making mine roofs less likely to collapse, saving thousands of lives; an IRS agent straight out of a crime thriller; and the manager who made the National Cemetery Administration the best-run organization, public or private, in the entire country. Each essay shines a spotlight on the essential behind-the-scenes work of exemplary federal employees.
Whether they’re digitizing archives, chasing down cybercriminals, or discovering new planets, these public servants are committed to their work and universally reluctant to take credit. Expanding on the Washington Post series, the vivid profiles in Who Is Government? blow up the stereotype of the irrelevant bureaucrat. They show how the essential business of government makes our lives possible, and how much it matters…(More)”.
Computer Science and the Law
Article by Steven M. Bellovin: “There were three U.S. technical/legal developments occurring in approximately 1993 that had a profound effect on the technology industry and on many technologists. More such developments are occurring with increasing frequency.
The three developments were, in fact, technically unrelated. One was a bill before the U.S. Congress for a standardized wiretap interface in phone switches, a concept that spread around the world under the generic name of “lawful intercept.” The second was an update to the copyright statute to adapt to the digital age. While there were some useful changes—caching proxies and ISPs transmitting copyrighted material were no longer to be held liable for making illegal copies of protected content—it also provided an easy way for careless or unscrupulous actors—including bots—to request takedown of perfectly legal material. The third was the infamous Clipper chip, an encryption device that provided a backdoor for the U.S.—and only the U.S.—government.
All three of these developments could be and were debated on purely legal or policy grounds. But there were also technical issues. Thus, one could argue on legal grounds that the Clipper chip granted the government unprecedented powers, powers arguably in violation of the Fourth Amendment to the U.S. Constitution. That, of course, is a U.S. issue—but technologists, including me, pointed out the technical risks of deploying a complex cryptographic protocol, anywhere in the world (and many other countries have since expressed similar desires). Sure enough, Matt Blaze showed how to abuse the Clipper chip to let it do backdoor-free encryption, and at least two other mechanisms for adding backdoors to encryption protocols were shown to have flaws that allowed malefactors to read data that others had encrypted.
These posed a problem: debating some issues intelligently required not just a knowledge of law or of technology, but of both. That is, some problems cannot be discussed purely on technical grounds or purely on legal grounds; the crux of the matter lies in the intersection.
Consider, for example, the difference between content and metadata in a communication. Metadata alone is extremely powerful; indeed, Michael Hayden, former director of both the CIA and the NSA, once said, “We kill people based on metadata.” The combination of content and metadata is of course even more powerful. However, under U.S. law (and the legal reasoning is complex and controversial), the content of a phone call is much more strongly protected than the metadata: who called whom, when, and for how long they spoke. But how does this doctrine apply to the Internet, a network that provides far more powerful abilities to the endpoints in a conversation? (Metadata analysis is not an Internet-specific phenomenon. The militaries of the world have likely been using it for more than a century.) You cannot begin to answer that question without knowing not just how the Internet actually works, but also the legal reasoning behind the difference. It took more than 100 pages for some colleagues and I, three computer scientists and a former Federal prosecutor, to show how the line between content and metadata can be drawn in some cases (and that the Department of Justice’s manuals and some Federal judges got the line wrong), but that in other cases, there is no possible line1

When data disappear: public health pays as US policy strays
Paper by Thomas McAndrew, Andrew A Lover, Garrik Hoyt, and Maimuna S Majumder: “Presidential actions on Jan 20, 2025, by President Donald Trump, including executive orders, have delayed access to or led to the removal of crucial public health data sources in the USA. The continuous collection and maintenance of health data support public health, safety, and security associated with diseases such as seasonal influenza. To show how public health data surveillance enhances public health practice, we analysed data from seven US Government-maintained sources associated with seasonal influenza. We fit two models that forecast the number of national incident influenza hospitalisations in the USA: (1) a data-rich model incorporating data from all seven Government data sources; and (2) a data-poor model built using a single Government hospitalisation data source, representing the minimal required information to produce a forecast of influenza hospitalisations. The data-rich model generated reliable forecasts useful for public health decision making, whereas the predictions using the data-poor model were highly uncertain, rendering them impractical. Thus, health data can serve as a transparent and standardised foundation to improve domestic and global health. Therefore, a plan should be developed to safeguard public health data as a public good…(More)”.
What Happens When AI-Generated Lies Are More Compelling than the Truth?
Essay by Nicholas Carr: “…In George Orwell’s 1984, the functionaries in Big Brother’s Ministry of Truth spend their days rewriting historical records, discarding inconvenient old facts and making up new ones. When the truth gets hazy, tyrants get to define what’s true. The irony here is sharp. Artificial intelligence, perhaps humanity’s greatest monument to logical thinking, may trigger a revolution in perception that overthrows the shared values of reason and rationality we inherited from the Enlightenment.
In 1957, a Russian scientist-turned-folklorist named Yuri Mirolyubov published a translation of an ancient manuscript—a thousand years old, he estimated—in a Russian-language newspaper in San Francisco. Mirolyubov’s Book of Veles told stirring stories of the god Veles, a prominent deity in pre-Christian Slavic mythology. A shapeshifter, magician, and trickster, Veles would visit the mortal world in the form of a bear, sowing mischief wherever he went.
Mirolyubov claimed that the manuscript, written on thin wooden boards bound with leather straps, had been discovered by a Russian soldier in a bombed-out Ukrainian castle in 1919. The soldier had photographed the boards and given the pictures to Mirolyubov, who translated the work into modern Russian. Mirolyubov illustrated his published translation with one of the photographs, though the original boards, he said, had disappeared mysteriously during the Second World War. Though historians and linguists soon dismissed the folklorist’s Book of Veles as a hoax, its renown spread. Today, it’s revered as a holy text by certain neo-pagan and Slavic nationalist cults.
Mythmaking, more than truth seeking, is what seems likely to define the future of media and of the public square.
Myths are works of art. They provide a way of understanding the world that appeals not to reason but to emotion, not to the conscious mind but to the subconscious one. What is most pleasing to our sensibilities—what is most beautiful to us—is what feels most genuine, most worthy of belief. History and psychology both suggest that, in politics as in art, generative AI will succeed in fulfilling the highest aspiration of its creators: to make the virtual feel more authentic than the real…(More)”
Accounting for State Capacity
Essay by Kevin Hawickhorst: “The debates over the Department of Government Efficiency have revealed, if nothing else, that the federal budget is obscure even to the political combatants ostensibly responsible for developing and overseeing it. In the executive branch, Elon Musk highlights that billions of dollars of payments are processed by the Treasury without even a memo line. Meanwhile, in Congress, Republican politicians highlight the incompleteness of the bureaucracy’s spending records, while Democrats bemoan the Trump administration’s dissimulation in ceasing to share budgetary guidance documents. The camp followers of these obscure programs are thousands of federal contractors, pursuing vague goals with indefinite timelines. As soon as the ink on a bill is dry, it seems, Congress loses sight of its initiatives until their eventual success or their all-too-frequent failure.
Contrast this with the 1930s, when the Roosevelt administration provided Congress with hundreds of pages of spending reports every ten days, outlining how tax dollars were being put to use in minute detail. The speed and thoroughness with which these reports were produced is hard to fathom, and yet the administration was actually holding its best information back. FDR’s Treasury had itemized information on hundreds of thousands of projects, down to the individual checks that were written. Incredibly, politicians had better dashboards in the era of punch cards than we have in the era of AI. The decline in government competence runs deeper than our inability to match the speed and economy of New Deal construction: even their accounting was better. What happened?
Political scientists discuss the decline in government competence in terms of “state capacity,” which describes a government’s ability to achieve the goals it pursues. Most political scientists agree that the United States not only suffers from degraded state capacity in absolute terms, but has less state capacity today than in the early twentieth century. A popular theory for this decline blames the excessive proceduralism of the U.S. government: the “cascade of rigidity” or the “procedure fetish.”
But reformers need more than complaints. To rebuild state capacity, reformers need an affirmative vision of what good procedure should look like and, in order to enact it, knowledge of how government procedure is changed. The history of government budgeting and accounting reform illustrates both. There were three major eras of reform to federal accounting in the twentieth century: New Deal reforms of the 1930s, conservative reforms of the 1940s and 1950s, and liberal reforms of the 1960s. This history tells the story of how accounting reforms first built up American state capacity and how later reforms contributed to its gradual decline. These reforms thus offer lessons on rebuilding state capacity today…(More)”.
“R&D” Means Something Different on Capitol Hill
Article by Sheril Kirshenbaum: “My first morning as a scientist-turned-Senate-staffer began with a misunderstanding that would become a metaphor for my impending immersion into the complex world of policymaking. When my new colleagues mentioned “R&D,” I naively assumed they were discussing critical topics related to research and development. After 10 or so confused minutes, I realized they were referring to Republicans and Democrats—my first lesson in the distinctive language and unique dynamics of congressional work. The “R&D” at the center of their world was vastly different than that of mine.In the 20 years since, I’ve moved between academic science positions and working on science policy in the Senate, under both Republican and Democratic majorities. My goal during these two decades has remained the same—to promote evidence-based policymaking that advances science and serves the public, regardless of the political landscape. But the transition from scientist to staffer has transformed my understanding of why so many efforts by scientists to influence policy falter. Despite generations of scholarly research to understand how information informs political decisions, scientists and other academics consistently overlook a crucial part of the process: the role of congressional staffers.
The staff hierarchy shapes how scientific information flows to elected officials. Chiefs of staff manage office operations and serve as the member’s closest advisors. Legislative directors oversee all policy matters, while legislative assistants (LAs) handle specific issue portfolios. One or two LAs may be designated as the office “science people,” although they often lack formal scientific training. Committee staffers provide deeper expertise and institutional knowledge on topics within their jurisdiction. In this ecosystem, few dedicated science positions exist, and science-related topics are distributed among staff already juggling multiple responsibilities…(More)”
Farmers win legal fight to bring climate resources back to federal websites
Article by Justine Calma: “After farmers filed suit, the US Department of Agriculture (USDA) has agreed to restore climate information to webpages it took down soon after President Donald Trump took office this year.
The US Department of Justice filed a letter late last night on behalf of the USDA that says the agency “will restore the climate-change-related web content that was removed post-inauguration, including all USDA webpages and interactive tools” that were named in the plaintiffs’ complaint. It says the work is already “underway” and should be mostly done in about two weeks.
If the Trump administration fulfills that commitment, it’ll be a significant victory for farmers and other Americans who rely on scientific data that has disappeared from federal websites since January…(More)”.
The Meanings of Voting for Citizens: A Scientific Challenge, a Portrait, and Implications
Book by Carolina Plescia: “On election day, citizens typically place a mark beside a party or candidate on a ballot paper. The right to cast this mark has been a historic conquest and today, voting is among the most frequent political acts citizens perform. But what does that mark mean to them? This book explores the diverse conceptualizations of voting among citizens in 13 countries across Europe, Africa, the Americas, and Oceania. This book presents empirical evidence based on nearly a million words about voting from over 25,000 people through an open-ended survey and both qualitative and quantitative methods. The book’s innovative approach includes conceptual, theoretical, and empirical advancements and provides a comprehensive understanding of what voting means to citizens and how these meanings influence political engagement. This book challenges assumptions about universal views on democracy and reveals how meanings of voting vary among individuals and across both liberal democracies and electoral autocracies. The book also examines the implications of these meanings for political behaviour and election reforms. The Meanings of Voting for Citizens is a critical reference for scholars of public opinion, behaviour, and democratization, as well as a valuable resource for undergraduate and graduate courses in comparative political behaviour, empirical methods, and survey research. Practitioners working on election reforms will find it particularly relevant via its insights into how citizens’ meanings of voting impact the effectiveness of electoral reforms…(More)”.
New data tools enhance the development effectiveness of tourism investment
Article by Louise Twining-Ward, Alex Pio and Alba Suris Coll-Vinent: “The tourism sector is a major driver of economic growth and inclusive job creation. Tourism generates a high number of jobs, especially for women (UN Tourism). In 2024, tourism was responsible for one in ten jobs worldwide, delivering 337.7 million total jobs, and accounted for 10.5 percent of global GDP . For many developing countries, it is a primary generator of foreign exchange.
The growth of this vital sector depends heavily on public investment in infrastructure and services. But rapid change, due to uncertain geopolitics, climate shocks, and shifting consumer behavior, can make it hard to know how best to spend scarce resources. Traditional data sources are unable to keep up, leaving policymakers without the timely insights needed to effectively manage mounting complexities. Only a few developing coutries collect and maintain tourism satellite accounts (TSAs), which help capture tourism’s contribution to their economies. However, even in these countries, tourist arrival data and spending behavior, through immigration data and visitor surveys, are often processed with a lag. There is an urgent need for more accessible, more granular, and more timely data tools.
Emerging Data Tools
For this reason, the World Bank partnered with Visa to access anonymized and aggregated credit card spend data in the Caribbean and attempt to fill data gaps. This and other emerging tools for policymaking—such as satellite and geospatial mapping, analysis of online reviews, artificial intelligence, and advanced analytics—now allow tourism destinations to take a closer look at local demand patterns, gauge visitor satisfaction in near-real time, and measure progress on everything from carbon footprints to women’s employment in tourism…(More)”.
