Rapid Spread

Verticillium wilt is becoming an increasing concern in artichoke production because the rapid spread of the disease to new growing areas has led to declining production. Scientists from Italy, Spain, and the United States combine to bring us up to date on diagnosis of the disease, its epidemiology and life cycle, as well as management strategies, current and forthcoming.

Tropical spiderwort (more appropriately called Benghal dayflower) poses a serious threat to crop production in the southern United States. Although tropical spiderwort has been present in the United States for more than seven decades, only recently has it become a pest in agricultural fields. Identified as an isolated weed problem in 1999, tropical spiderwort became the most troublesome weed in Georgia cotton by 2003. Contributing to the significance of tropical spiderwort as a troublesome weed is the lack of control afforded by most commonly used herbicides, especially glyphosate. Vegetative growth and flower production of tropical spiderwort were optimized between 30 and 35 C, but growth was sustained over a range of 20 to 40 C. These temperatures are common throughout much of the United States during summer months. At the very least, it appears that tropical spiderwort may be able to co-occur with cotton throughout the southeastern United States. The environmental limits of tropical spiderwort have not yet been determined. However, the rapid spread through Georgia and naturalization in North Carolina, coupled with its tolerance to current management strategies and aggressive growth habit, make tropical spiderwort a significant threat to agroecosystems in the southern United States.

Verticillium wilt, caused by the fungus Verticillium dahliae, is the most important and destructive disease of mint (Mentha spp.) in the United States (U.S.). The disease was first observed in commercial mint fields in the Midwestern U.S. in the 1920s and, by the 1950s, was present in mint producing regions of the U.S. Pacific Northwest. Verticillium wilt continues to be a major limiting factor in commercial peppermint (Mentha x piperita) and Scotch spearmint (Mentha x gracilis) production, two of the most important sources of mint oil in the U.S. The perennial aspect of U.S. mint production, coupled with the soilborne, polyetic nature of V. dahliae, makes controlling Verticillium wilt in mint a challenge. Studies investigating the biology and genetics of the fungus, the molecular mechanisms of virulence and resistance, and the role of soil microbiota in modulating host-pathogen interactions are needed to improve our understanding of Verticillium wilt epidemiology and inform novel disease management strategies. This review will discuss the history and importance of Verticillium wilt in commercial U.S. mint production, as well as provide a format to highlight past and recent research advances in an effort to better understand and manage the disease.

Transnational Citizenship

In the context of research on the “thickening” of borders, Specters of Belonging raises the related question: How does transnational citizenship thicken across the political life cycle of Mexican migrants? In addressing this question, this book resembles what any good migration corrido (ballad) does—narrate the thickening of transnational citizenship from beginning, middle, to end. Specifically, Specters of Belonging traces Mexican migrant transnationalism across the migrant political life cycle, beginning with the “political baptism” (i.e., naturalization in the United States) and ending with repatriation to México after death. In doing so, the book illustrates how Mexican migrants enunciate, enact, and embody transnational citizenship in constant dialectical contestation with the state and institutions of citizenship on both sides of the U.S.-México border. Drawing on political ethnographies of citizenship classrooms, the first chapter examines how Mexican migrants enunciate transnational citizenship as they navigate the naturalization process in the United States and grapple with the contradictions of U.S. citizenship and its script of singular political loyalty. The middle chapter deploys transnational ethnography to analyze how Mexican migrants enact transnational citizenship within the clientelistic orbit of the Mexican state, focusing on a group of returned migrant politicians and transnational activists. Last, the final chapter turns to how Mexican migrants embody transnational citizenship by tracing the cross-border practice of repatriating the bodies of deceased Mexican migrants from the United States to their communities of origin in rural México.

Abstract Over the last decade, communities have become increasingly aware of the risks they face. They are threatened by natural disasters, which may be exacerbated by climate change and the movement of land masses. Growing globalization has made a pandemic due to the rapid spread of highly infectious diseases ever more likely. Societal discord breeds its own threats, not the least of which is the spread of radical ideologies giving rise to terrorism. The accelerating rate of technological change has bred its own social and economic risks. This widening spectrum of risk poses a difficult question to every community – how resilient will the community be to the extreme events it faces. In this paper, we present a new approach to answering that question. It is based on the stress testing of financial institutions required by regulators in the United States and elsewhere. It generalizes stress testing by expanding the concept of “capital” beyond finance to include the other “capitals” (e.g., human, social) possessed by a community. Through use of this approach, communities can determine which investments of its capitals are most likely to improve its resilience. We provide an example of using the approach, and discuss its potential benefits.

This article reviews the contributions of the Panel Study of Income Dynamics (PSID) to the study of intergenerational mobility. The PSID enables researchers to track individuals as they form new households and covers many dimensions of socioeconomic status over large portions of the life cycle, making the data ideal for studying intergenerational mobility. Studies have used PSID data to show that the United States is among the least economically mobile countries among advanced economies. The PSID has been instrumental to understanding various dimensions of intergenerational mobility, including occupation; wealth; education; consumption; health; and group differences by gender, race, and region. Studies using the PSID have also cast light on the mechanisms behind intergenerational persistence.

Near Future

The pandemic has enhanced the social function of digital technologies and services. It is solely through digital technology that a massive shift to remote work has been possible during the most difficult period of the pandemic. All over the world, the philosophy of office work is changing, and there is a transition to permanent and conditional-permanent remote work. For example, Transport Canada is planning to move to telecommuting as a key employment model for its employees. In the near future, telecommuting will continue for most of the 6,000 employees in the agency. In China, widespread use of WeChat, Tencent, and Ding digital working applications began in late January 2020, when isolation measures were introduced. In Switzerland, COOVID-19 Remote Work and Study Resources provides free resources for remote operation and distance learning. Zoom and Google Meet videoconferencing, remote workplaces, and new social platforms run remote work almost immediately, and this trend is likely to continue after the lifting of the quarantine. Trends in staff employment worldwide are rather mixed. According to LinkedIn, it is possible to track changes in the employment rates of seven key economies – Australia, China, France, Italy, Singapore, Great Britain and United States. In France and Italy, the decline was more pronounced at -70% and -64.5% respectively by mid-April 2020. Since then, employment has been gradually recovering, and most of the seven key economies for which these figures have been analysed tend to change by 0 per cent year on year. By July 1, 2020, China, France, and the United States had seen the largest rebound in relative recruitment – -6% or -7%. At the end of September 2020, the countries with a high recovery in employment were China (22 per cent), Brazil (13 per cent), Singapore (8 per cent) and France (5 per cent). In these economies, hiring so far seems to compensate for months in which no new personnel have been recruited, indicating some stabilization of the labor market.
