Human mobility is crucial to understand the transmission pattern of COVID-19 on spatially embedded geographic networks. This pattern seems unpredictable, and the propagation appears unstoppable, resulting in over 350,000 death tolls in the U.S. by the end of 2020. Here, we create the spatiotemporal inter-county mobility network using 10 TB (Terabytes) trajectory data of 30 million smart devices in the U.S. in the first six months of 2020. We investigate the bond percolation process by removing the weakly connected edges. As we increase the threshold, the mobility network nodes become less interconnected and thus experience surprisingly abrupt phase transitions. Despite the complex behaviors of the mobility network, we devised a novel approach to identify a small, manageable set of recurrent critical bridges, connecting the giant component and the second-largest component. These adaptive links, located across the United States, played a key role as valves connecting components in divisions and regions during the pandemic. Beyond, our numerical results unveil that network characteristics determine the critical thresholds and the bridge locations. The findings provide new insights into managing and controlling the connectivity of mobility networks during unprecedented disruptions. The work can also potentially offer practical future infectious diseases both globally and locally.

AbstractThis Article discusses the impact of the international financial crisis on Brazilian capital markets. While the banking industry was not severely affected, leading nonfinancial corporations experienced severe financial turmoil. Two Brazilian corporations cross-listed in the United States - Sadia S.A. and Aracruz Celulose S.A. - suffered billion-dollar losses when the Brazilian real unexpectedly plummeted in relation to the dollar. Despite earlier disclosure that these companies had engaged only in pure hedging activity, these great losses were found to be the result of their highly speculative trading in currencyderivatives. Consequently, several private lawsuits were filed both in the United States and in Brazil.This Article takes a novel approach to the transnational securities litigation debate by examining the particular consequences of private litigation in a developed and in an emerging country. It compares the types of lawsuits filed and their final outcomes. Despite substantially similar alleged wrongdoing, the outcomes for securities holders in each jurisdiction contrast strikingly. Only U.S. investors of both companies were able to obtain substantial financial recoveries; Brazilian investors obtained none. This Article examines the reasons behind these discrepant results and the consequent economic distributional effects on global securities markets after the U.S. Supreme Court decision in Morrison.The Article argues that Morrison aggravates such (i) shareholder cross-border non pro rata compensation and (ii) transfers of company value from foreign to U.S. investors. It identifies a set of costs borne by foreign investors, and so far neglected by scholars, as a consequence of the current status of U.S. and international securities law regimes. These costs are the result not only of the typical “circularity problem” in securities litigation, but also of a “double circularity problem” as they fall on foreign shareholders who also suffered equivalent damages to those experienced by the U.S. class being compensated. The Article then discusses potential policy reforms for fixing transnational securities litigation.

An American Language is a political history of the Spanish language in the United States. The nation has always been multilingual and the Spanish language in particular has remained as an important political issue into the present. After the U.S.-Mexican War, the Spanish language became a language of politics as Spanish speakers in the U.S. Southwest used it to build territorial and state governments. In the twentieth century, Spanish became a political language where speakers and those opposed to its use clashed over what Spanish's presence in the United States meant. This book recovers this story by using evidence that includes Spanish language newspapers, letters, state and territorial session laws, and federal archives to profile the struggle and resilience of Spanish speakers who advocated for their language rights as U.S. citizens. Comparing Spanish as a language of politics and as a political language across the Southwest and noncontiguous territories provides an opportunity to measure shifts in allegiance to the nation and exposes differing forms of nationalism. Language concessions and continued use of Spanish is a measure of power. Official language recognition by federal or state officials validates Spanish speakers' claims to US citizenship. The long history of policies relating to language in the United States provides a way to measure how U.S. visions of itself have shifted due to continuous migration from Latin America. Spanish-speaking U.S. citizens are crucial arbiters of Spanish language politics and their successes have broader implications on national policy and our understanding of Americans.

In 2013, the Walt Disney Company submitted an application to trademark “Día de los muertos” (Day of the Dead) as they prepared to launch a holiday themed movie. Almost immediately after this became public Disney faced such strong criticism and backlash they withdrew their petition. By October of 2017 Disney/Pixar released the animated film Coco. Audiences in Mexico and the U.S. praised it's accurate and authentic representation of the celebration of Day of the Dead. In this essay, I argue that despite its generic framing, Coco mobilizes many elements of horror in its account of Miguel's trespassing into the forbidden space of the dead and his transformation into a liminal figure, both dead and alive. Specifically, with its horror so deftly deployed through tropes and images of borders, whether between life and death or the United States and Mexico, Coco falls within a new genre, the border horror film.

This section, updated regularly on the blog Palestine Square, covers popular conversations related to the Palestinians and the Arab-Israeli conflict during the quarter 16 November 2017 to 15 February 2018: #JerusalemIstheCapitalofPalestine went viral after U.S. president Donald Trump recognized Jerusalem as the capital of Israel and announced his intention to move the U.S. embassy there from Tel Aviv. The arrest of Palestinian teenager Ahed Tamimi for slapping an Israeli soldier also prompted a viral campaign under the hashtag #FreeAhed. A smaller campaign protested the exclusion of Palestinian human rights from the agenda of the annual Creating Change conference organized by the US-based National LGBTQ Task Force in Washington. And, UNRWA publicized its emergency funding appeal, following the decision of the United States to slash funding to the organization, with the hashtag #DignityIsPriceless.

There are over 1,000 McDonald's on French soil. Two Disney theme parks have opened near Paris in the last two decades. And American-inspired vocabulary such as “le weekend” has been absorbed into the French language. But as former French president Jacques Chirac put it: “The U.S. finds France unbearably pretentious. And we find the U.S. unbearably hegemonic.” Are the French fascinated or threatened by America? They Americanize yet are notorious for expressions of anti-Americanism. From McDonald's and Coca-Cola to free markets and foreign policy, this book looks closely at the conflicts and contradictions of France's relationship to American politics and culture. The book shows how the French have used America as both yardstick and foil to measure their own distinct national identity. France has charted its own path: it has welcomed America's products but rejected American policies; assailed Americ's “jungle capitalism” while liberalizing its own economy; attacked “Reaganomics” while defending French social security; and protected French cinema, television, food, and language even while ingesting American pop culture. The book examines France's role as an independent ally of the United States, but he also considers the country's failures in influencing the Reagan, Bush, and Clinton administrations. Whether investigating France's successful information technology sector or its spurning of American expertise during the AIDS epidemic, the book asks if this insistence on a French way represents a growing distance between Europe and the United States or a reaction to American globalization. Exploring cultural trends, values, public opinion, and political reality, this book delves into the complex relationship between two modern nations.

Most histories of Catholicism in the United States focus on the experience of Euro-American Catholics, whose views on social issues have dominated public debates. This book provides a comprehensive overview of the Latino Catholic experience in America from the sixteenth century to today, and offers the most in-depth examination to date of the important ways the U.S. Catholic Church, its evolving Latino majority, and American culture are mutually transforming one another. This book highlights the vital contributions of Latinos to American religious and social life, demonstrating in particular how their engagement with the U.S. cultural milieu is the most significant factor behind their ecclesial and societal impact.

Under the United States Alien Tort Statute, which permits non-U.S. citizens to bring lawsuits in U.S. courts for human rights violations that are violations of the law of nations, plaintiffs have filed claims against multinational oil and gas corporations for the direct or complicit commission of such violations carried out by the government of the country in which the corporation operated. In addition to exercising jurisdiction over U.S. corporations, U.S. courts have exercised jurisdiction in cases involving non-U.S. defendants for alleged wrongful conduct against non-U.S. plaintiffs committed outside the U.S.The exercise of jurisdiction by U.S. courts over non-U.S. defendants for alleged wrongful conduct against non-U.S. plaintiffs committed outside of the U.S. raises serious questions as to the jurisdictional foundation on which the power of U.S. courts to adjudicate them rests. Defences that foreign defendants can raise against the exercise of jurisdiction by the U.S. courts are an objection to the extraterritorial assertion of jurisdiction, the act of state doctrine, the political question doctrine, forum non conveniens, and the principle of comity. These defences are bolstered by the support of the defendant’s home government and other governments.
