Porcine deltacoronavirus (δ-CoV) is the object of extensive research in several countries including the United States. In contrast, the epidemiology of δ-CoVs in wild birds in the US is largely unknown. Our aim was to comparatively assess the prevalence of δ- and γ-CoVs in wild migratory terrestrial and aquatic birds in Arkansas, Illinois, Indiana, Maryland, Mississippi, Missouri, Ohio, Tennessee and Wisconsin. A total of 1236 cloacal/fecal swabs collected during the period 2015–2018 were tested for γ- and δ-CoVs using genus-specific reverse transcription-PCR assays. A total of 61 (4.99%) samples were γ-CoV positive, with up to 29 positive samples per state. In contrast, only 14 samples were positive for δ-CoV (1.14%) with only 1–4 originating from the same state. Thus, unlike previous reports from Asia, γ-CoVs are more prevalent than δ-CoVs in the US, suggesting that δ-CoVs may spread in birds with lower efficiency. This may indicate δ-CoV emerging status and incomplete adaptation to new host species limiting its spread. Phylogenetic analysis of the partial N gene revealed that the newly identified δ-CoV strains were most closely related to the HKU20 (wigeon) strain. Further studies are necessary to investigate the role of aquatic bird δ-CoVs in the epidemiology of δ-CoVs in swine and terrestrial birds.

The article analyzes the US policy towards Ukraine dating back from the time before the reunification of Crimea with Russia and up to Donald Trump coming to power. The spectrum of Washington’s interests towards this country being of particular strategic interest to the United States are disclosed. It should be noted that since the disintegration of the Soviet Union Washington’s interest in this country on the whole has not been very much different from its stand on all post-Soviet states whose significance was defined by the U,S depending on their location on the world map as well as on the value of their natural resources. However, after the reunification of Crimea with Russia Washington’s stand on this country underwent significant changes, causing a radical transformation of the U,S attitude in their Ukrainian policy. During the presidency of Barack Obama the American policy towards Ukraine was carried out rather sluggishly being basically declarative in its nature. When President D. Trump took his office Washington’s policy towards Ukraine became increasingly more offensive and was characterized by a rather proactive stance not only because Ukraine became the principal arena of confrontation between the United States and the Russian Federation, but also because it became a part of the US domestic political context. Therefore, an outcome of the “battle” for Ukraine is currently very important for the United States in order to prove to the world its role of the main helmsman in the context of a diminishing US capability of maintaining their global superiority.

In both the United States and Canada, bankruptcy preferential transfer avoidance provisions are aimed at creating equality of distribution among similarly situated creditors. However, there is a key difference in the way each jurisdiction’s regime treats the notion of intent. An analysis of each regime, using examples, illustrates the way in which Canada’s regime effectually does violence to the distributive equality policy objective, while the US regime adheres to it.

Jimmy Carter was elected President of the United States in November 1976. A few months earlier, the Italian elections marked an extraordinary result for the Italian Communist Party (PCI), and some of its members obtained institutional roles. During the electoral campaign, members of Carter's entourage released declarations that seemed to prelude to abandoning the anti-communist veto posed by previous governments. For a year after the inauguration, the US administration maintained an ambiguous position. Nonetheless, on 12 January 1978, the United States reiterated its opposition to any forms of participation of communists in the Italian government. Drawing on a varied set of sources and analysing the role of non-state actors, including think tanks and university centres, this article examines the debate on the Italian "communist question" within the Carter administration and among its advisers. Such discussion will be placed within a wider debate that crossed America's liberal culture.

This chapter traces the development of the medical interpreting profession in the United States as a case study. It begins with the conception of interpreters as volunteer helpers or dual-role medical professionals who happened to have some knowledge of languages other than English. Then it examines the emergence of training programs for medical interpreters, incipient efforts to impose standards by means of certification tests, the role of government in providing language access in health care, and the beginning of a labor market for paid medical interpreters. The chapter concludes with a description of the current situation of professional medical interpreting in the United States, in terms of training, certification and the labor market, and makes recommendations for further development.

There is no shortage of scholarly and other research on the reciprocal relationship that inequality bears to crime, victimisation and contact with the criminal justice system, both in the specific United States context and beyond. Often, however, inequality has been studied in conjunction with only one of the three phenomena at issue, despite the intersections that arguably obtain between them–and, indeed, between their respective connections with inequality itself. There are, moreover, forms of inequality that have received far less attention in pertinent research than their prevalence and broader significance would appear to merit. The purpose of this chapter is dual: first, to identify ways in which inequality’s linkages to crime, victimisation and criminal justice may relate to one another; and second, to highlight the need for a greater focus than has been placed heretofore on the role of institutionalised inequality of access to the political process, particularly as this works to bias criminal justice policy-making towards the preferences of financially motivated state lobbying groups at the expense of disadvantaged racial minorities. In so doing, the chapter singles out for analysis the US case and, more specifically, engages with key extant explanations of the staggering rise in the use of imprisonment in the country since the 1970s.

We present rearing records of Agromyzidae (Diptera) from five years of collecting throughout the United States. We review host and distribution data, and describe leaf mines, for 93 species, plus 28 others that could not be confidently identified in the absence of male specimens. We report 147 new host species records, including the first rearing records for Agromyza bispinata Spencer, A. diversa Johnson, A. parca Spencer, A. pudica Spencer, A. vockerothi Spencer, Calycomyza michiganensis Steyskal, Ophiomyia congregata (Malloch), and Phytomyza aldrichi Spencer. Phytomyza anemones Hering and (tentatively identified) Cerodontha (Dizygomyza) iraeos (Robineau-Desvoidy) are new to North America; Agromyza albitarsis Meigen, Amauromyza shepherdiae Sehgal, Aulagromyza populicola (Walker), Liriomyza orilliensis Spencer, Phytomyza linnaeae (Griffiths), P. solidaginivora Spencer, and P. solidaginophaga Sehgal are new to the USA. We also present confirmed USA records for Calycomyza menthae Spencer (previous records were based only on leaf mines), Ophiomyia maura (Meigen) (reported from the USA in older literature but deleted from the fauna in the most recent revision (Spencer & Steyskal 1986)), and Phytomyza astotinensis Griffiths and P. thalictrivora Spencer (previously only tentatively recorded from the USA). We provide 111 additional new state records. We describe the following 30 new species: Agromyza fission, A. soka, Melanagromyza palmeri, Ophiomyia euthamiae, O. mimuli, O. parda, Calycomyza artemisivora, C. avira, C. eupatoriphaga, C. vogelmanni, Cerodontha (Dizygomyza) edithae, Cer. (D.) feldmani, Liriomyza ivorcutleri, L. valerianivora, Phytomyza actaeivora, P. aesculi, P. confusa, P. doellingeriae, P. erigeronis, P. hatfieldae, P. hydrophyllivora, P. palmeri, P. palustris, P. sempervirentis, P. tarnwoodensis, P. tigris, P. triangularidis, P. vancouveriella, P. verbenae, and P. ziziae.

Understanding the spatial or geographical dependence of income inequality and regional inequality is crucial in the study of inequality. This paper employs a multi-scale, multi-mechanism framework to map and analyze historical patterns of regional and income inequality in the United States (US) by using state and regional panel data spanning over a century. To explore the patterns systematically and see the role of spatial partitioning, we organize the data around several established geographical partitions before conducting various geographical information system (GIS) analyses and statistical techniques. We also investigate the spatial dependence of income inequality and regional inequality. We find that spatial autocorrelation exists for both types of inequality in the US. However, the magnitude of spatial dependence for regional inequality is declining whereas it is volatile for income inequality over time. While income inequality has been at its peak in the most recent decades, we also notice that regional inequality is at its lowest point. As for the choice of partitioning, we observe that within inequality dominates for Census Divisions and Bureau of Economic Analysis (BEA) regions. Conversely, we see that between inequality overall contributes the most to the inequality among Census Regions.

President Obama's and President Xi Jinping's visits to Tanzania — and the associated jubliation and fanfare accompanying them — seem to validate much of what has been written in the past few years of the supposed competition between the United States and China for influence and resources in Africa, with many authors proclaiming that the U.S. was losing this competition. Aside from propagating the idea that Africa is some sort of homogenous collection of people, ideas, and cultures, many of these authors view the role of Africa as primarily an economic battleground in which the U.S and China must battle to determine control while ignoring the fact that the differing strengths and focuses of the American and Chinese economies do not lend themselves to any sort of outright competition in Africa.
