AbstractSARS-CoV-2 is transmitted primarily through close, person-to-person interactions. Physical distancing policies can control the spread of SARS-CoV-2 by reducing the amount of these interactions in a population. Here, we report results from four waves of contact surveys designed to quantify the impact of these policies during the COVID-19 pandemic in the United States. We surveyed 9,743 respondents between March 22 and September 26, 2020. We find that interpersonal contact has been dramatically reduced in the US, with an 82% (95%CI: 80%–83%) reduction in the average number of daily contacts observed during the first wave compared to pre-pandemic levels. However, we find increases in contact rates over the subsequent waves. We also find that certain demographic groups, including people under 45 and males, have significantly higher contact rates than the rest of the population. Tracking these changes can provide rapid assessments of the impact of physical distancing policies and help to identify at-risk populations.

Over Time

SARS-CoV-2 is spread primarily through person-to-person contacts. Quantifying population contact rates is important for understanding the impact of physical distancing policies and for modeling COVID-19, but contact patterns have changed substantially over time due to shifting policies and behaviors. There are surprisingly few empirical estimates of age-structured contact rates in the United States both before and throughout the COVID-19 pandemic that capture these changes. Here, we use data from six waves of the Berkeley Interpersonal Contact Survey (BICS), which collected detailed contact data between March 22, 2020 and February 15, 2021 across six metropolitan designated market areas (DMA) in the United States. Contact rates were low across all six DMAs at the start of the pandemic. We find steady increases in the mean and median number of contacts across these localities over time, as well as a greater proportion of respondents reporting a high number of contacts. We also find that young adults between ages 18 and 34 reported more contacts on average compared to other age groups. The 65 and older age group consistently reported low levels of contact throughout the study period. To understand the impact of these changing contact patterns, we simulate COVID-19 dynamics in each DMA using an age-structured mechanistic model. We compare results from models that use BICS contact rate estimates versus commonly used alternative contact rate sources. We find that simulations parameterized with BICS estimates give insight into time-varying changes in relative incidence by age group that are not captured in the absence of these frequently updated estimates. We also find that simulation results based on BICS estimates closely match observed data on the age distribution of cases, and changes in these distributions over time. Together these findings highlight the role of different age groups in driving and sustaining SARS-CoV-2 transmission in the U.S. We also show the utility of repeated contact surveys in revealing heterogeneities in the epidemiology of COVID-19 across localities in the United States.

Abstract: The object of the study was to evaluate the risk factors associated with accepting online misinformation about COVID-19 vaccination in the United States. The percentages of fully vaccinated people, with regards to COVID-19, were considered as a surrogate measure of accepting online misinformation. The study evaluated the impact of the US state's average intelligence quotient (IQ) and per capita income on accepting misinformation. The study found that socio-demographic groups with lower income along with lower intelligence quotient (IQ) are more vulnerable to online misinformation theories surrounding COVID-19. Further study is needed to evaluate how to increase the intelligence quotient among low-income individuals and whether such an effort will reduce the acceptance of misinformation among the vulnerable population in the United States.

This study examines the impact of monetary and fiscal policies on the stock market in the United States (US), were used. By employing the method of Autoregressive Distributed Lags (ARDL) developed by Pesaran et al. (2001). Annual data from the Federal Reserve, World Bank, and International Monetary Fund, from 1986 to 2017 pertaining to the American economy, the results show that both policies play a significant role in the stock market. We find a significant positive effect of real Gross Domestic Product and the interest rate on the US stock market in the long run and significant negative relationship effect of Consumer Price Index (CPI) and broad money on the US stock market both in the short run and long run. On the other hand, this study only could support the significant positive impact of tax revenue and significant negative impact of real effective exchange rate on the US stock market in the short run while in the long run are insignificant.

Abstract Food insecurity is an under-recognized geriatric syndrome that has extensive implications in the overall health and well-being of older adults. Understanding the impact of food insecurity in older adults is a first step in identifying at-risk populations and provides a framework for potential interventions in both hospital and community-based settings. This symposium will provide an overview of current prevalence rates of food insecurity using large population-based datasets. We will present a summary indicator that expands measurement to include the functional and social support limitations (e.g., community disability, social isolation, frailty, and being homebound), which disproportionately impact older adults, and in turn their rate and experience of food insecurity and inadequate food access. We will illustrate using an example of at-risk seniors the association between sarcopenia, the age-related loss of muscle mass and function, with rates of food security in the United States. The translational aspect of the symposium will then focus on identification of psychosocial and environmental risk factors including food insecurity in older veterans preparing for surgery within the Veterans Affairs Perioperative Optimization of Senior Health clinic. Gaining insights into the importance of food insecurity will lay the foundation for an intervention for food insecurity in the deep south. Our discussant will provide an overview of the implications of these results from a public health standpoint. By highlighting the importance of food insecurity, such data can potentially become a framework to allow policy makers to expand nutritional programs as a line of defense against hunger in this high-risk population.

The Impact

The murder of George Floyd by a police officer in the United States in May 2020 and the subsequent turmoil, as well as the violence against migrants on the US-Mexican border, have drawn major public and media attention to the phenomenon of police brutality (see, e.g., Levin 2020; Misra 2018; Taub 2020), which is often labeled as ‘militarization of police’. At the same time, in recent years military forces have been increasingly involved in policing missions in civilian environments, both domestically (see, e.g., Kanno-Youngs 2020; Schrader 2020; Shinkman 2020) and abroad. The convergence of military conduct and policing raises intriguing questions regarding the impact of these tendencies on the military and the police, as well as on their legitimacy.

This article examines the ebb and flow of the Quebec government’s economic and commercial relations with the United States in the period 1994–2017. The topic demonstrates the impact of three major forces on Quebec’s economic and commercial ties with the US: (1) the North American Free Trade Agreement (NAFTA) which became operational in 1994 and was fully implemented over a 15-year period; (2) the onerous security policies put in place by the US government in the decade following the horrific events of 11 September 2001; and (3) changing economic circumstances in the United States ranging from robust growth to the worst recession since the Great Depression of the 1930s. The article also indicates that the Quebec government continues to sponsor a wide range of activities in the United States, often more elaborate and extensive than comparable activities pursued by many nation-states with representation in the US. 1 1 Stéphane Paquin, ‘Quebec-U.S. Relations: The Big Picture’, American Review of Canadian Studies 46, no. 2 (2016): 149–61.

The Impact

As part of its “War on Terror”, the United States (US) provided immense sums of money and advanced equipment to Afghan warlords in order to defeat and dismantle the Taliban and al-Qaeda in Afghanistan. Nearly two decades after the 2001 US-led intervention in Afghanistan that toppled the Taliban regime, the US continues supporting the warlords in various ways. As the intervention was also aimed at establishing a functioning state and reconstruction of the war-torn country, the US needed the support of local warlords to achieve its goals. However, over time, warlords and warlordism became a major challenge to the postTaliban state-building project and in many ways undermined the overall security and the state monopoly on violence. These warlords, who had been mostly expelled and defeated by the Taliban regime, returned under the aegis of the B52 bombers, recaptured parts of the country and reestablished their fiefdoms with US support and resources. They not only resist giving up the power and prestige they have accumulated over the past few years, but also hamper the effort to improve governance and enact necessary reforms in the country. In addition, many of them run their private militias and have been accused of serious human rights abuses as well as drug trafficking, arms smuggling, illegal mining and extortion in the areas under their control or influence. In many ways, they challenge the government authority and have become a major hurdle to the country’s emerging from lawlessness and anarchy. This paper explores the emergence and reemergence of warlords in Afghanistan as well as the evolution of chaos and anarchy in the country, especially after the US-led intervention of late 2001. It also analyzes the impact of the post-9/11 US support to Afghan warlords and its negative consequences for the overall stability and the US-led state-building process in Afghanistan.

Chapter 1 by Rafael Marquese compares the impact of the demise of slavery in the US and Brazil and the transformation of the coffee economies and cotton economies. Marquese connects American Reconstruction with larger global processes to explore the reorganization of the national state and American capitalism that took place in the Era of Globalization (1870–1914). He shows how “Second Slavery,” a concept articulated by Dale Tomich, provides a model for understanding both the integrated trajectory of slavery in Brazil and the United States and the ways the coffee plantationa and economies and the cotton plantations and economies of these nations interacted after emancipation.

The Impact

This article contends that Western Europe played a crucial and overlooked role in the collapse of Bretton Woods. Most scholars highlight the role of the United States, focusing on the impact of US balance of payments deficits, Washington’s inability to manage inflation, the weakness of the US dollar, and American domestic politics. Drawing on archival research in Britain, Germany, the Netherlands, and the United States, this article argues that Western European decisions to float their currencies at various points from 1969 to 1973 undermined the fixed exchange rate system. The British, Dutch, and West Germans opted to float their currencies as a means of protecting against imported inflation or protecting their reserve assets, but each float reinforced speculators’ expectations that governments would break from their fixed parities. The acceleration of financial globalization and the expansion of the Euromarkets in the 1960s made Bretton Woods increasingly difficult to defend.

Museums Connect is a program funded by the US Department of State and administered by the American Alliance of Museums that sponsors transnational museum partnerships. This program provides one model for teaching public history in a transnational context, and this article analyzes the experiences of two university-museums—the Museum of History and Holocaust Education (MHHE) in the United States and the Ben M’sik Community Museum (BMCM) in Morocco—during two grants between 2009 and 2012. In exploring the impact of the program on the staff, faculty, and students involved and by analyzing the experiences and reflections of participants, I argue that this program can generate positive pedagogical experiences. However, in addition to the successes of the MHHE and BMCM during their two grants, the participants encountered significant power differentials that manifested themselves in both the processes and products of the grants. It is the conclusion of this article that both partners in a public history project need to address and confront potential power issues at the outset in order to achieve a more balanced, collaborative partnership.
