In this paper the primary types of Centris bees described by the British entomologist Theodore Dru Alison Cockerell deposited in the Natural History Museum (London) and the Oxford University Museum of Natural History (Oxford) in the United Kingdom, as well as in the United States National Museum (Washington), American Museum of Natural History (New York), the Academy of Natural Sciences of Drexel University (Philadelphia), and in the California Academy of Sciences (San Francisco) in the United States were studied. To stabilize the application of the name C. lepeletieri (= C. haemorrhoidalis (Fabricius)), a lectotype is designated. The study of the primary types allow proposing the revalidation of C. cisnerosi nom. rev. from the synonymy of C. agilis Smith, C. nitida geminata nom. rev. from C. facialis Mocsáry, C. rufulina nom. rev. from C. varia (Erichson), C. semilabrosa nom. rev. from C. terminata Smith and C. triangulifera nom. rev. from C. labrosa Friese. Centris bakeri syn. nov., C. bimaculata carrikeri syn. nov., C. fusciventris matoensis syn. nov., C. heterodonta syn. nov. and C. elegans grenadensis syn. nov. are proposed as a new junior synonyms of C. varia, C. claripennis Friese nom. rev., C.  caurensis, C. dentata Smith and C. elegans Smith, respectively. Centris ruae is withdrawn from the synonymy of C. transversa Pérez and proposed as a new junior synonym of C. nitida Smith. In addition, a lectotype for C. buchholzi Herbst (= C. wilmattae) is designated. Information on the repository of the lectotype of C. lepeletieri and images of most primary types studied here are also provided.

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.

Every child has a right to an education. In the United States, the issue is not necessarily about access to a school but access to a quality education. With strict compulsory education laws, more than 50 million students enrolled in primary and secondary schools, and billions of dollars spent annually on public and private education, American children surely have access to buildings and classrooms. However, because of a complex and competitive system of shared policymaking among national, state, and local governments, not all schools are created equal nor are equal education opportunities available for the poor, minorities, and underprivileged. One manifestation of this inequity is the lack of qualified teachers in many urban and rural schools to teach certain subjects such as science, mathematics, and technology. The purpose of this article is to describe a partnership model between two major institutions (The American Museum of Natural History and The City University of New York) and the program designed to improve the way teachers are trained and children are taught and introduced to the world of science. These two institutions have partnered on various projects over the years to expand educational opportunity especially in the teaching of science. One of the more successful projects is Seminars on Science (SoS), an online teacher education and professional development program, that connects teachers across the United States and around the world to cutting-edge research and provides them with powerful classroom resources. This article provides the institutional perspectives, the challenges and the strategies that fostered this partnership.

How does the prevalence of COVID-19 impact people’s mental health? In a preregistered study (N = 857), we sought to answer this question by comparing demographically matched samples in four regions in the United States and Italy with different levels of cumulative COVID-19 prevalence. No main effect of prevalence emerged. Rather, prevalence region had opposite effects, depending on the country. New York City participants (high prevalence) reported more general distress, PTSD symptoms, and COVID-19 worry than San Francisco (low prevalence). Conversely, Campania participants (low prevalence) reported more general distress, PTSD symptoms, and COVID-19 worry than Lombardy (high prevalence). Consistent with these patterns, COVID-19 worry was more strongly linked with general distress and PTSD symptoms in New York than San Francisco, whereas COVID-19 worry was more strongly linked with PTSD in Campania than Lombardy. In exploratory analyses, media exposure predicted and mapped on to geographic variation in mental health outcomes.

William Diller Matthew was the eldest child of Dr. G. E. Matthew, of New Brunswick, an amateur geologist, who, by his great collections and excellent papers, added much to our knowledge of that part of Canada. Dr. Matthew was born on February 19,1871, in St. John, New Brunswick ; throughout his life he retained an interest in this town, visiting it yearly, except when abroad, and retaining his Canadian nationality during nearly forty years’ residence in the United States. Dr. Matthew was introduced to geological methods by his father, and sent at first to the small University of Halifax, whence in 1892 he proceeded to Columbia University as a graduate-student, there studying geology, mineralogy and metallurgy. He graduated Ph.D. in 1895. In that year he was selected by Professor H. F. Osborn, whose classes he had attended, as assistant in the department of Vertebrate Palaeontology in the American Museum of Natural History, New York. In this department he worked for thirty-two years, finally becoming Curator-in-chief of the division of geology, mineralogy and palaeontology.

Asians and Asian Americans are the most suburbanized people of color in the United States. While Asians and Asian Americans have been moving to the metropolitan fringe since the 1940s, their settlement accelerated in the 1970s, 1980s, and 1990s. This was partly the result of relaxed US immigration policies following the 1965 Hart-Celler Act. Globalization and burgeoning transnational economies across the so-called Pacific Rim also encouraged outmigration. Whether it is Korean or Indian immigrants in northern New Jersey or Vietnamese refugees in suburban Houston, Asians and Asian Americans have shifted Americans’ understandings of “typical” suburbia. In the late 1980s, academic researchers and policymakers started paying closer attention to this phenomenon, especially in Southern California, where Asians and Asian Americans often clustered together in select suburbs. Sociologists, in particular, observed how greater Los Angeles’s economic, political, and built landscapes changed as immigrants and refugees—predominantly from Hong Kong, Taiwan, the Philippines, South Korea, India, and Vietnam—established roots throughout the region, including Orange County. Since then, other studies of heavily populated Asian and Asian American ethnic suburbs—or “ethnoburbs”—have emerged, including research on New York City, Boston, and Washington, DC. Nonetheless, scholarship remains focused on Southern California, the San Francisco Bay Area, and other hubs of the metropolitan West Coast. Research and scholarship on Asians and Asian Americans living in the suburbs has grown over the last decade. This is partly a response to demographic shifts occurring beyond the coasts. Moreover, geographers, historians, and urban planners have joined the discussion, producing critical studies on race, class, architecture, and political economy. Despite the breadth and depth of recent research, literature on Asian and Asian American suburbanization remains limited. There is thus much room for additional research on this subject, given a majority of Asians and Asian Americans in the United States live outside city limits.

During a career that spanned four decades, Russian artist Vasily Konovalenko (1929–1989) produced more than 70 sculptures carved from gems, minerals, and other raw materials. As unorthodox, compelling, and masterful as Konovalenko's sculptures are, they had been poorly published and poorly known. They are on permanent display at only two museums in the world: the small and obscure State Gems Museum (Samotsvety) in Moscow, Russia, and the Denver Museum of Nature & Science (DMNS), a major natural history museum in Colorado, the United States. This article examines Konovalenko's life and work, as well as the unusual circumstances that led to the two exhibitions, their role in Konovalenko's relative obscurity, and a recent resurgence of interest.

The material on which this article is based was sent to Dr. R. T. Leiper, C.M.G., F.R.S., by Mr. L. R. Hutson, Veterinary Officer, Antigua, to both of whom my thanks are due. Most of the cestodes had already been described by Prof. J. G. Baer and recorded by him in 1940. The rest of the collection consists mainly of nematodes but there are, however, representatives of all three groups of helminths—Trematoda, Cestoda and Acanthocephala as well as the Nematoda. The hosts were all described by the local popular names and I am much indebted to Mr. Kinnear, of the Natural History Museum, London, for identifying them.The only trematode in the collection is the Strigeid, Apharyngostrigca cornu Goeze, 1800, which had been removed from the large gut of a Yellow crowned night heron, Nycticorax violaceous. It has already been recorded from a number of birds belonging to the Ciconidae and to the Ardeidae but not from this particular host. It is not uncommon in Europe and the United States but has not been reported in the British West Indies before. There are two specimens both attached to the mucous membrane but they were easily removed and seemed to have caused no pathological changes. They are mature and contain eggs and the vitellaria are strongly developed, obscuring most of the other organs.
