The Spanish influenza arrived in the United States at a time when new forms of mass transportation, mass media, mass consumption, and mass warfare had vastly expanded the public places in which communicable diseases could spread. Faced with a deadly "crowd" disease, public health authorities tried to implement social-distancing measures at an unprecedented level of intensity. Recent historical ...

Taxonomic uncertainty as to the identities of Hyalomma (Euhyalomma) scupense Schulze, 1919 and Hyalomma detritum Schulze, 1919 has existed for nearly 85 years. The chief criterion used to consider these taxa as separate species has been an ecological feature, namely that H. scupense is a one-host tick while H. detritum is a two-host species. Morphologically they are identical. To date no compre...

We provide accounts of four species of Synelmis Chamberlin, 1919 (Annelida: Phyllodocida: Pilargidae) from Australian and adjacent seas, including one new species, S. sergi sp. nov. The only previous, positively identified, record of a Synelmis species in the region, S. gibbsi Salazar-Vallejo, 2003, has been checked and the specimens re-identified here as S. knoxi Glasby, 2003, which extends th...

The influenza pandemic of 1918-1919 killed at least 50 million people. The reasons why this pandemic was so deadly remain largely unknown [9]. However, It has been shown that the 1918 viral hemagglutinin allows to reproduce the hallmarks of the illness observed during the original pandemic [11]. Thanks to the wealth of hemagglutinin sequences accumulated over the last decades, amino-acid substi...

Introduction An early textbook in hydrology (Mead 1919) contains a remarkable chapter on ground water as well as two chapters on geology. The author, Daniel W. Mead, a professor of hydraulic and sanitary engineering at the University of Wisconsin (now the University of WisconsinMadison), based the text on lecture notes (published earlier, Mead [1904]) for his course in general hydrology. In fac...

A population of the gall midge Pumilomyia protrahenda De Stefani, 1919 causing galls on Artemisia arborescens (Asteraceae) was discovered near Palermo (Sicily) in 2008. This species had not been found since 1918. Detailed study of morphological characters of adults, larvae and pupae revealed that Pumilomyia protrahenda belongs to the genus Rhopalomyia Rübsaamen, 1892, tribe Rhopalomyiini. The m...

Almost all deaths related to current influenza epidemics occur among the elderly. However, mortality was greatest among the young during the 1918-1919 pandemic. This study compared the age distribution of influenza-related deaths in the United States during this century's three influenza A pandemics with that of the following epidemics. Half of influenza-related deaths during the 1968-1969 infl...

Riegeriana gen. nov. is described to accommodate Physopelta apicalis Walker, 1873. A lectotype of Ph. apicalis is de-signated. Iphita fasciata Stehlík & Jindra, 2008, syn. nov., is recognized as a new junior subjective synonym of Riegeriana apicalis. In addition, Iphita lata sp. nov. is described from southern India and a check-list of the species of the genus Iphita Stål, 1873 is provided. The...

During the 1918-1919 influenza pandemic in the United States, most cities responded by implementing community mitigation strategies, such as school closure. However, three cities--New York City, Chicago, and New Haven, Connecticut--diverged from the dominant pattern by keeping their public schools open while the pandemic raged. This article situates the experiences of these three cities in the ...
