Abstract E. ophiuroides is a perennial grass that has been intentionally introduced into tropical and warm temperate areas to be used as a lawn grass (USDA-ARS, 2016). In the United States it has become a common lawn grass principally in the southeastern states (Brosnan and Deputy, 2008; Duble, 2016). However, in the USA, it also behaves as a weed principally in disturbed sites and along roadsides (Coile, 1993; USDA-NRCS, 2016) and Miller et al. (2010) recently reported that it is invading natural and disturbed areas across the southern states. It is also listed as an invasive grass in Puerto Rico (Rojas-Sandoval and Acevedo-Rodríguez, 2015). E. ophiuroides spreads easily by seeds and by stolons and grows forming dense mats of prostrate, low-growing stems and leaves (Brosnan and Deputy, 2008). Plants also recover quickly after fire (Walsh, 1994).

The work is devoted to the analysis of a collection prepared by a group of American researchers on the historical past and present of the situation of Hispanic population in the United States of America, which raises the problem of segregation of Hispanics at the federal level. In the 21st century, ethnic Hispanics are becoming one of the largest population groups in the United States, and Spanish is the second most widely used language after English in this country, which makes the issue raised in the monograph under review very relevant. The authors of the collection focused their research on the features of segregation of Latin Americans in the states of the Sunbelt, thereby clearly limiting the regional scope of their research. By their publications, they prove that the southern states of the United States have turned into carceral states for Latin Americans.

Percent resistance and minimum inhibitory concentrations (MIC) were described for canine (n = 301) and feline (n = 75) pathogenic Escherichia coli (E. coli) isolates solicited during May 2005 to Sep 2005 from the Clinical Pharmacology Laboratory at Auburn University (n = 165) or commercial diagnostic laboratories ([CDL]; n = 211) from four regions in the USA. Drugs tested were amoxicillin (AMX), amoxicillin trihydrate/clavulanate potassium (AMXC), cefpodoxime (CFP), doxycycline (DXY), enrofloxacin (ENR), gentamicin (GM) and trimethoprim-sulfamethoxazole (TMS). Urinary isolates were most common (n = 174). Percent resistance was greatest for isolates from the respiratory tract, urine, and skin compared with the ear. Resistance was also greatest for samples sent from the south and central states compared with the western states (P ≤ 0.001). Percent resistance by drug was AMX (46 ± 2.6%) > AMXC (37 ± 2.5%) > CFP (21.8 ± 2%) = DXY (22 ± 2.1%) = ENR (20 ± 2.1%) = TMS (19 ± 2%) > GM (12 ± 1.7%). There was a significant difference in resistance between the different antibiotic drugs (P ≤ 0.001). Population MIC distributions were bimodal, and MICs were highest in samples from the southern states (P ≤ 0.001). E. coli resistance may limit its empirical treatment. For susceptible isolates, AMX and AMXC may be least effective and TMS most effective.

AbstractWith the passage of the Jones Act (1917), the United States expanded Puerto Rican autonomy, made Puerto Ricans citizens of the USA, and gave the island prohibition of alcohol. The Puerto Rican people overwhelmingly ratified prohibition in a referendum in July 1917. Prohibition won because it was emotionally linked to patriotism and morality. Prohibition enforcement was almost impossible, compounded by the colonial status of the island. It was that status which brought an immediate end to prohibition in Puerto Rico with the demise of prohibition in the United States in 1933.

he systemic crisis of old industrial regions in many countries of the world is a very important historical phenomenon of recent decades. This article examines the decline of traditional industrialism in the Great Lakes region of the United States as an example of such events. The article covers the first stage of the regional crisis (the mid-1960s – early 1980s). The study is based on historical statistics, as well as on various non-quantitative data. It is argued that the onset of the crisis was associated with aggravated competition – basic sectors of the local economy (steel manufacturing, automotive industry, etc.) were increasingly lagging behind advanced factories located in the southern states of the USA, as well as in Japan and Western Europe. Later the region (with some differences by industry and state) faced very deep failures during recessions of 1969–1970, 1974–1975 and 1980–1982, also experiencing constant pressure due to the high dollar exchange rate. However, a further deterioration in the early 1980s drew public attention to the situation in the region, which contributed to the turn of local and federal authorities to more active anti-crisis politics.

Abstract P. aurea is a highly invasive running bamboo native to Southeast China that is now widespread globally and especially problematic in Australia and North America. This woody, rhizomatous perennial grass rapidly forms a dense monoculture, suffocating other native plants and altering the entire ecosystem. As well as having detrimental effects on the environment this bamboo may also damage property and poses a potential threat to human health as it harbours a fungus responsible for the disease Histoplasmosis. Invasive bamboos are among the fastest growing plants on Earth and one infestation of P. aurea can spread as far as 9.3 miles. The spread is rapid in all directions, increasing each successive year. It is listed as invasive in Australia, New Zealand, Hawaii, Reunion, Brazil, Costa Rica, Cuba, USA, Mexico, Spain and France. In the United States, it is listed as naturalized or invasive in 273 counties including the mid-Atlantic region of the USA, Pennsylvania, Maryland, Virginia, West Virginia, and Georgia. It is reported as fully naturalizing in New Zealand, with infestations forming dense stands, and some invading national parks. In Australia, this species is regarded as an environmental weed in Queensland and New South Wales.

Introduction: The federal government estimates that per mile traveled in 2018, the number of deaths on motorcycles was nearly 27 times the number in cars. In the United States there is no universal helmet law. In twenty-two states, motorcycle helmets are entirely optional, while in nineteen states and the District of Columbia universal motorcycle helmets laws requiring helmets for all riders regardless of age are implemented and nine states only require younger motorcycle riders to wear a helmet, with varying age limits. Objectives: The overall objectives of this study were to evaluate the following: (1) number of fatalities (with and without helmet use), (2) fatality rate per motorcycle registration, (3) fatality percentage with age, (4) percent fatality due to alcohol impairment, and (5) location of collision impact to the rider in two southern states (Mississippi and Alabama) where helmet laws are established compared with a southern state (Florida) that only requires riders less than 20 years of age to be helmeted. Methods: Data from 2015-2018 were obtained from the National Highway Transportation Safety Administration Reporting System (FARS) and supplemented with state related and CDC data. Results: In all three states, the most common collision was a front-end impact. Mississippi had the highest percentage of motorcycle fatalities even with >80% of riders helmeted when the fatal accident occurred, followed by Florida motorcyclist who are only 50% of the time helmeted. In all three southern states similar percentage of fatalities were seen in each age group with higher fatalities associated with age range of 30-39 years. Conclusions: Variables such as helmet type, distance from a level 1 trauma center, poor roads, weather conditions, and visibility of the rider may also be factors that contribute to a higher incidence of fatality and need to be further investigated to improve motorcycle safety.

Abstract I. rugosum is a C4 grass species widely cultivated and naturalized in moist, tropical habitats around the world (Clayton et al., 2015; USDA-ARS, 2015). It is an opportunistic and effective colonizer of open and disturbed areas, swamps, and along roadsides. It is a serious weed in many crops, especially in paddy fields and sugarcane plantations (Holm et al., 1977; Baki and Manidool, 1992). I. rugosum is a highly invasive grass which can produce up to 4,000 seeds per plant and has the potential to grow even in shaded areas (Holm et al., 1977; PROTA, 2015). I. rugosum is listed as invasive in Costa Rica, Cuba, the Dominican Republic and Fiji (Kairo et al., 2003; Chacon and Saborio, 2012; Oviedo Prieto et al., 2012; PIER, 2015). In the USA, the Department of Agriculture considers it a noxious weed; plants found growing within the continental USA should be promptly reported to that agency (Barkworth et al., 2003).

Interest in the fate of the German psychoanalysts who had to flee Hitler's Germany and find refuge in a new nation, such as the United States, has increased. The ‘émigré research’ shows that several themes recur: (1) the theme of ‘loss’ of one's culture, homeland, language, and family; and (2) the ambiva-lent welcome these émigrés received in their new country. We describe the political-social-cultural context that existed in the United States during the 1930s, 1940s and 1950s. Documentary evidence found in the FBI files of three émigré psychoanalysts, Clara Happel, Martin Grotjahn, and Otto Fenichel, are then presented in combination with other source material. This provides a provisional impression of how each of these three individuals experienced their emigration. As such, it gives us elements of a history. The FBI documents suggest that the American atmosphere of political insecurity and fear-based ethnocentric nationalism may have reinforced their old fears of National Socialism, and contributed to their inclination to inhibit or seal off parts of them-selves and their personal histories in order to adapt to their new home and become Americanized. They abandoned the rich social, cultural, political tradition that was part of European psychoanalysis. Finally, we look at these elements of a history in order to ask a larger question about the appropriate balance between a liberal democratic government's right to protect itself from internal and external threats on the one hand, or crossover into the blatant invasion of civil rights and due process on the other.

Sandra Ramos (b. 1969) is one of the few artists to reflect critically on both sides of the Cuban di-lemma, fully embodying the etymological origins of the word in ancient Greek: di-, meaning twice, and lemma, denoting a form of argument involving a choice between equally unfavorable alternatives. Throughout her works she shines a light on the dilemmas faced by Cubans whether in Cuba or the United States, underlining the bad personal and political choices people face in both countries. During the hard 1990s, while still in Havana, the artist focused on the traumatic one-way journey into exile by thousands, as well as the experience of profound abandonment experienced by those who were left behind on the island. Today she lives in Miami and operates a studio there as well as one in Havana. Her initial disorientation in the USA has morphed into an acerbic representation and critique of the current administration and a deep concern with the environmental collapse we face. A buffoonlike Trumpito has joined el Bobo de Abela and Liborio in her gallery of comic characters derived from the rich Cuban graphic arts tradition where she was formed. While Cuba is now represented as a rotten cake with menacing flies hovering over it ready to pounce, a bombastic Trumpito marches across the world stage, trampling everything underfoot, a dollar sign for a face.
