Crabapples (Malus spp.) are commonly planted ornamental trees in public and private landscapes. Hundreds of selections are available that represent a wide range of growth habits, ornamental traits, and varying degrees of resistance/susceptibility to disease. We distributed 1810 questionnaires in 13 states (Oregon, Washington, Utah, Colorado, Minnesota, Iowa, Missouri, Illinois, Indiana, Michigan, Ohio, New York, and Pennsylvania) to members of either nursery and landscape associations or the Associated Landscape Contractors of America (ACLA, Herndon, Va.) to identify crabapple preferences across a broad geographic region of the United States. We also were interested in learning if regional disease problems were important to green-industry professionals as they decide which crabapples to include in their inventories. Our respondent population numbered 511 (28.2% response rate). A large percentage of respondents (79.4%) said their retail clients focused mostly on fl ower color when choosing crabapples for the home landscape, while commercial clients showed slightly more interest in growth habit (32.5%) than fl ower color (28.7%). `Prairifire' was identified by respondents in all regions, except the west-central (Colorado and Utah), as the crabapple most frequently recommended to clients when tree size is not important. Respondents in the west-central region most often (48.7%) recommend the fruitless selection `Spring Snow'. Respondents in all regions, except the west-central, identified apple scab (Venturia inaequalis) as the most prevalent crabapple disease and named scab-susceptible `Radiant' as the selection most frequently discontinued.

Gerald Handerson Thayer (1883–1939) was an artist, writer and naturalist who worked in North and South America, Europe and the West Indies. In the Lesser Antilles, Thayer made substantial contributions to the knowledge and conservation of birds in St Vincent and the Grenadines. Thayer observed and collected birds throughout much of St Vincent and on many of the Grenadines from January 1924 through to December 1925. Although he produced a preliminary manuscript containing interesting distributional notes and which is an early record of the region's ornithology, Thayer never published the results of his work in the islands. Some 413 bird and bird egg specimens have survived from his work in St Vincent and the Grenadines and are now housed in the American Museum of Natural History (New York City) and the Museum of Comparative Zoology (Cambridge, Massachusetts). Four hundred and fifty eight specimens of birds and eggs collected by Gerald and his father, Abbott, from other countries are held in museums in the United States.

Organized crime is spreading like a global virus as mobs take advantage of open borders to establish local franchises at will. That at least is the fear, inspired by stories of Russian mobsters in New York, Chinese triads in London, and Italian mafias throughout the West. As this book explains, the truth is more complicated. The author has spent years researching mafia groups in Italy, Russia, the United States, and China, and argues that mafiosi often find themselves abroad against their will, rather than through a strategic plan to colonize new territories. Once there, they do not always succeed in establishing themselves. The book spells out the conditions that lead to their long-term success, namely sudden market expansion that is neither exploited by local rivals nor blocked by authorities. Ultimately the inability of the state to govern economic transformations gives mafias their opportunity. In a series of matched comparisons, the book charts the attempts of the Calabrese 'Ndrangheta to move to the north of Italy, and shows how the Sicilian mafia expanded to early twentieth-century New York, but failed around the same time to find a niche in Argentina. The book explains why the Russian mafia failed to penetrate Rome but succeeded in Hungary. A pioneering chapter on China examines the challenges that triads from Taiwan and Hong Kong find in branching out to the mainland. This book is both a compelling read and a sober assessment of the risks posed by globalization and immigration for the spread of mafias.

Every few decades, the world order changes due to various geopolitical, economic and other circumstances. For example, as a result of globalization, the world order has undergone significant changes in the last forty years. Globalization has led to the destruction of the postwar world order, as well as to world leadership by the United States and the West. However, in recent decades, as a result of globalization, the U.S. and the West began to cede their leadership to developing countries, so there is now a change in the economic structure of relations in the world system. Today the center of economic growth is in the East, namely in Asia. There are no new superpowers in the world at the moment, but the unipolar world will cease to exist due to the weakening of the U. S. leadership, which will lead to a change in the world order. A new leader, which may replace the U. S., will not have as wide range of advantages as the USA has. Most likely, the essence of the new order will be to unite the largest countries and alliances into blocks, for example, the USA together with the Trans-Pacific Partnership, the EU, etc. The article outlines forecasts of GDP growth rates as well as the global energy outlook; analyzes the LNG market as well as the impact of the pandemic on the global oil and gas market; and lists the characteristics of U. S. geopolitics.

One of the most boldly conceived assaults on benighted Africa during the nineteenth century was that undertaken by mainline Protestant denominations in the United States. With the brash confidence characteristic of the age, hundreds of American missionaries were dispatched from New York and Baltimore to convert the heathen tribes of Africa and wrest a continent from ruin. If the experience of the Protestant Episcopal church is at all typical, however, these efforts not infrequently aroused suspicion and open hostility. In fact, Episcopal penetration of Liberia in the second half of the second century was remarkable for a long and bitter contest with black nationalists who were intent on using the church as a vehicle for their own personal and racial ambitions.

In the United States, populations of the apple scab pathogen Venturia inaequalis have progressed through three consecutive rounds of fungicide resistance development, first to dodine, then to the benzimidazoles, and most recently to the sterol demethylation inhibitors (DMIs). Analysis of extensive monitoring data have to date provided no indication of detectable cross-resistance or partial cross-resistance of V. inaequalis populations to the three unrelated classes of fungicides prior to the selection of resistant subpopulations. However, in this study, resistance to both benomyl and DMIs developed to significantly higher frequencies within the previously established dodine-resistant population than in the population sensitive to dodine. Accelerated selection of phenotypes double resistant to dodine and the DMI fenarimol was apparent over the course of distinct seasons of apple scab management with either dodine or fenarimol. The data provide evidence for an accelerated speed of resistance development among phenotypes of V. inaequalis already resistant to an unrelated fungicide. This finding represents a departure from the previous model, which assumed entirely independent rounds of resistance developments. The data indicate that phenotypes of V. inaequalis might not only be selected for the trait of fungicide resistance but also for traits allowing a more flexible response to changes in the environment where they compete.

Many individuals and organizations have had a part in the making of this book. They have described influences and forces whose interaction has resulted in the present pattern of our hospital services, and documented their interpretations. The result is a source book of basic information which should be valuable for all students of hospital problems. The Commission was appointed by the American Hospital Association, and chosen to represent a wide range of those providing hospital, health and welfare services, as well as the consuming public.

This chapter examines the shift in global balance that began in the post-2007 economic crisis. For a considerable time before the 2008 crisis, the United States and most European states had been living on high levels of debt both national and individual, public and private. Manufacturing in the developed West, and its provision of secure jobs for many workers, was undermined by the new economic environment of globalization, as well as the growth of cheaper manufacturing in China and the other BRIC countries. A new epoch of financial capitalism, which had emerged since the 1980s, was in full swing by the start of the Noughties. The chapter first considers the post-2007 economic crisis, before discussing the continuing rise of China and Russian foreign policy under Vladimir Putin. It concludes with an assessment of international reactions to China’s rise, including those of East Asia, international organizations, and Taiwan.

The Genesee Valley has long been recognized as a center of Iroquois development, but the connection between Owasco sites in the Genesee and Iroquois sequences in the adjacent regions has never been adequately demonstrated. Attempts to identify transitional Owasco-Iroquois sites in this region have been hampered by the use of diagnostic criteria based on data from eastern New York. This article examines ceramic patterns in the Genesee and establishes a regional cultural sequence based on ceramic criteria which have local diagnostic significance. This sequence reveals the transition from Owasco to Iroquois culture begins in the Genesee with a sudden influx of Ontario Iroquois ceramic traits from the west ca. 1250 A.D. This Owasco-Ontario Iroquois connection in the Genesee negates certain assumptions regarding Iroquois origins and alters our current concept of in situ development.
