The study described in this manuscript analyzed the effects of quarantine and social distancing policies implemented due to the Coronavirus Disease 2019 (COVID-19) pandemic on air pollution levels in four western megacities: São Paulo in Brazil; Paris in France; and Los Angeles and New York in the United States. The study investigated the levels of four air pollutants—Carbon monoxide (CO), Ozone (O3), Fine Particulate (PM2.5) and Nitrogen dioxide (NO2)—during the month of March 2020, compared to 2015–2019, in the urban air of these metropolitan areas, controlling for meteorological variables. Results indicated reductions in the levels of PM2.5, CO and NO2, with reductions of the latter two showing statistical significance. In contrast, tropospheric ozone levels increased, except in Los Angeles. The beneficial health effects of cleaner air might also help prevent deaths caused by the epidemic of COVID-19 in megacities by diminishing pressure on hospitals and health equipment. Future actions for the re-starting of non-essential economic activities in these cities should take into consideration the overall importance of health for the individual, as well as for societies.

Many observers have noted that immigrants to the United States are highly concentrated in the largest metropolitan areas of a relatively few states. Though immigrants diffused into many places that had previously seen relatively few immigrants during the 1990s, as of the 2000 census, 77 percent of the nation's 31.1 million foreign born residents still lived in six states – California, New York, Texas, Florida, New Jersey, and Illinois. According to the 2000 census, the two largest metropolitan areas, Los Angeles and New York, accounted for one third of all immigrants ( http://www.census.gov/Press-Release/www/2002/demoprofiles.html ). While immigrants moved into many new areas during the 1990s, making the challenge of incorporating their children a national issue, their concentration in our largest cities remained pronounced.

Abstract. Background: US suicide rates correlate with firearm availability. Little is known about variability in rates across countries. Aims: To observe the relationship between firearm/overall suicide rates in Toronto, Canada, and the five most populous US metropolitan areas. Method: Centers for Disease Control suicide rates by age and sex for New York, Los Angeles, Chicago, Dallas-Fort Worth, and Houston metropolitan areas were compared with equivalent data for Toronto (1999–2015). Results: Suicide rates by firearm, per 100,000 population, ranged from 0.45 in Toronto to 6.03 in Houston while rates by other methods ranged from 4.34 in Dallas-Fort Worth to 7.11 in Toronto. Overall rates of suicide ranged from 6.14 in New York to 10.45 in Houston. The two cities with the highest firearm suicide rates, Dallas-Fort Worth and Houston, also had much higher overall rates. Firearm suicides were most common in men over the age of 65 in all cities. Limitations: This study could not account for cultural differences between cities/countries. Conclusion: Much higher overall rates of suicide observed for Dallas-Fort Worth and Houston appear to be associated with high rates of suicide by firearm. Advocacy for means safety should target cities with high rates of firearm suicide and, in particular, elderly men.

In the 1970s, Japanese cooks began to appear in the kitchens of nouvelle cuisine chefs in France for further training, with scores more arriving in the next decades. Paul Bocuse, Alain Chapel, Joël Robuchon, and other leading French chefs started visiting Japan to teach, cook, and sample Japanese cuisine, and ten of them eventually opened restaurants there. In the 1980s and 1990s, these chefs' frequent visits to Japan and the steady flow of Japanese stagiaires to French restaurants in Europe and the United States encouraged a series of changes that I am calling the “Japanese turn,” which found chefs at fine-dining establishments in Los Angeles, New York City, and later the San Francisco Bay Area using an ever-widening array of Japanese ingredients, employing Japanese culinary techniques, and adding Japanese dishes to their menus. By the second decade of the twenty-first century, the wide acceptance of not only Japanese ingredients and techniques but also concepts like umami (savory tastiness) and shun (seasonality) suggest that Japanese cuisine is now well known to many American chefs.

This paper describes the relation between values and behavior of a new life style, that of voluntary simplicity which is characterized by low consumption, self-sufficiency, and ecological responsibility. Also, specific hypotheses regarding the motivation for voluntary simplicity and adoption in two areas of the United States were tested. Analysis shows (a) values of voluntary simplicity and behaviors are consistent, (b) the motivation for voluntary simplicity includes personal preference and economic hardship, and (c) adoption of voluntary simplicity is different in the Denver and New York City metropolitan areas.

In 1967 the 90th Congress of the United States attached an amendment to the Partnership for Health Act requiring the Secretary of the Department of Health, Education, and Welfare to undertake a survey of "the incidence and location of serious hunger and malnutrition–in the United States." In response to the legislative mandate the Ten-State Nutrition Survey was conducted during the years 1968 through 1970. The sample was selected from urban and rural families living in the following ten states: New York, Massachusetts, Michigan, California, Washington, Kentucky, West Virginia, Louisiana, Texas, and South Carolina. The families selected were those living in some of the census enumeration districts that made up the lowest economic quartiles of their respective states at the time of the 1960 census. During the eight years after the 1960 census the social and economic characteristics found in some of the individual enumeration districts had changed, so that there was a significant numer of families in the surveys with incomes well above the lowest income quartile. Thus, it was possible in analyzing results to make some comparisons on an economic basis. Thirty thousand families were identified in the selection process; 23,846 of these participated in the survey. Data regarding more than 80,000 individuals were obtained through interviews and 40,847 of these individuals were examined. The survey included the following: extensive demographic information on each of the participating families; information regarding food utilization of the family; a 24-hour dietary recall for infants up to 36 months of age, children 10 to 16 years of age, pregnant and lactating women, and individuals over 60 years of age.

Walter Hopps was an American art dealer and curator of modern and contemporary art. Best known for organizing the first museum retrospective of Marcel Duchamp in 1963 at the Pasadena Art Museum (now the Norton Simon), Hopps was a pioneering example of the independent, creative curator, a model that emerged in the 1960s in the United States From his start as an organizer of unconventional shows of California painters on the cultural fringe of conservative Cold War-era Los Angeles, Hopps became one of the most respected, if unorthodox, curators of his generation, holding a dual appointment at the end of his life as 20th-century curator at Houston’s Menil Collection and adjunct senior curator at the Solomon R. Guggenheim Museum in New York. Some of his noted exhibitions include: in Pasadena, a 1962 group show that helped to define pop art, The New Paintings of Common Objects; the first U retrospectives of Kurt Schwitters (1962) and Joseph Cornell (1967); Robert Rauschenberg retrospectives in 1976 and 1997 at the National Museum of American Art and Menil Collection, respectively; a 1996 survey of Edward Kienholz for The Whitney Museum of American Art; and a James Rosenquist retrospective in 2002 at the Guggenheim.

One of the first full-time newspaper dance reviewers in the United States, John Martin wrote for The New York Times from 1927 to 1962 and was often referred to as the dean of American dance critics during his 35-year tenure. Martin used his bully pulpit at the Times to launch a discourse within the dance community surrounding the aesthetics of modernism in dance as well as to educate and rally a new audience. In the process he helped to establish dance reviewing as a specialized field of arts reporting and commentary and not just a subgenre of music criticism, as it had been treated before 1927. A vocal defender of the legitimacy of an American modern dance as defined by New York-based practitioners such as Martha Graham and Doris Humphrey, Martin was among the first theorists of it, outlining a poetics of its form and function while introducing a new vocabulary. His prolific output includes thousands of essays and reviews for the Times and other periodicals, seven books, and a series of highly influential lectures given at the New School for Social Research, Bennington School of the Dance, and in the latter part of his career at the University of California-Los Angeles.

Confucian heritage culture holds that a good education is the path to upward social mobility as well as the road to realizing an individual’s fullest potential in life. In both China and Chinese diasporic communities around the world, education is of utmost importance and is central to childrearing in the family. In this paper, we address one of the most serious resettlement issues that new Chinese immigrants face—children’s education. We examine how receiving contexts matter for parenting, what immigrant parents do to promote their children’s education, and what enables parenting strategies to yield expected outcomes. Our analysis is based mainly on data collected from face-to-face interviews and participant observations in Chinese immigrant communities in Los Angeles and New York in the United States and in Singapore. We find that, despite different contexts of reception, new Chinese immigrant parents hold similar views and expectations on children’s education, are equally concerned about achievement outcomes, and tend to adopt overbearing parenting strategies. We also find that, while the Chinese way of parenting is severely contested in the processes of migration and adaptation, the success in promoting children’s educational excellence involves not only the right set of culturally specific strategies but also tangible support from host-society institutions and familial and ethnic social networks. We discuss implications and unintended consequences of overbearing parenting.
