Abstract Thymophylla tenuiloba is a small annual or short-lived perennial herb native to Texas and northern Mexico. It is used as an ornamental species and has escaped from cultivation in some parts of its distribution range. It is reported as invasive in the Bahamas, Hawaii and in some of the US states bordering the Gulf Coast. No details are available on its invasiveness and its effect over other species or habitats. T. tenuiloba is listed as an alien species in Anguilla, Cuba and parts of the USA; it is included in the Global Invasive Species Database but with no further information and also listed as a species of concern to Pacific ecosystems. T. tenuiloba is considered to be potentially invasive in Saba and Curaçao and listed as an environmental weed in Queensland, Australia.

AbstractWe discuss the most recent changes in smoking policies and support for smoking cessation offered to smokers at US workplaces. We used reports of employed adults (n = 112,008) regarding smoking restrictions and support for smoking cessation offered at their indoor workplaces from the 2010–11 and 2014–15 Tobacco Use Supplement–Current Population Survey. The percentage of adults who reported having workplace smoking restrictions was 94% in 2010–11 and 93% in 2014–15 (P = 0.001). There was a decrease in the Northeastern region (P < 0.001) and no significant changes in the other three US regions. The percentages decreased in Hawaii, New York, Oregon, Pennsylvania, and Tennessee and increased in Indiana, Nebraska, and Wyoming. The percentage of employees who reported having workplace support for smoking cessation increased from 24% to 29% (P < 0.001), which was uniform across all US regions but differed across the US states. The percentages decreased in Hawaii and increased in the majority of states. Analysis of smokers' reports (versus all reports) resulted in lower percentages of workplaces with smoking restrictions and support for smoking cessation. It is essential to further enhance support for smoking cessation offered to smokers at US workplaces.

On 29 August 2005, Hurricane Katrina hit the Gulf Coast of the USA to become one of the worst natural disasters in the country's history. The forecasts and official warnings of the event issued by the US National Hurricane Center up to 60 h ahead were excellent and largely based on an ‘ensemble’ of model and statistical guidance. The Met Office Global Model is highlighted as one of the best performers for Hurricane Katrina. The active 2005 Atlantic hurricane season has fuelled the debate on the impact of climate change on tropical cyclones. Some recent publications have suggested that this impact is already apparent, while others are more cautious. Inconsistencies remain among many of the theoretical, modelling and observational studies. Despite the excellent warnings, there was a tragic loss of life as a result of Hurricane Katrina which has led to political questions concerning complex socio-economic issues, the state of flood defences and how to coordinate the reaction to and mitigate the impact of such monumental natural hazards.

Investors' decisions are largely influenced by the riskiness of the country. Several different approaches are available to calculate this risk, but even so, the values set by Damodaran are usually used, even for non-US states. The aim of the paper is to propose a methodology for creating a risk premium in the environment of the Czech Republic and then compare it with Damodaran [1]. Methods applicable in the Czech Republic and Damodaran methods are used, then these methods are compared. For Czech as well as foreign investors, the easiest way to obtain a risk premium is to use the company’s investment rating. In the case of determining the risk premium of the Czech Republic, the easiest method is the CRP (country risk premiums) model. If the country’s market does not have a long history or does not have such a developed capital market, it is recommended to apply data from the US capital market. However, there are significant differences in the economy between Europe and the USA, so the data of an European country such as Germany, which has historical risk premium calculations, should be used.

Abstract M. jalapa is a perennial herb in tropical and subtropical regions (Encyclopedia of Life, 2016). It is an annual in temperate climates (Dave's Garden, 2016). It has been introduced into various continents as an ornamental since the 1500's (Le Duc, 1995; Encyclopedia of Life, 2016). The species is listed as invasive in Asia (China, Indonesia, Maldives, Philippines), Africa (Kenya, Seychelles, South Africa, Uganda), South America (Chile, Ecuador) and Oceania (Cook Islands, Federated States of Micronesia, Fiji, Hawaii-USA, Kiribati, Nauru, New Caledonia, New Zealand, Niue, Pitcairn, Tonga, US Minor Outlying Islands) (BioNET-EAFRINET, 2016; Invasive Species South Africa, 2016; PIER, 2016). Oviedo Prieto et al. (2012) consider it a species with the potential of becoming invasive in Cuba. It has also been separately reported as invasive in Ethiopia, Malawi, Rwanda, Tanzania and Zambia. Although its popularity has decreased (Flora of India, 2015; Missouri Botanical Garden, 2017), the species is still popular in some countries and it is available from nurseries and over the internet worldwide (Fuentes Fiallo et al., 2001; Dave's Garden, 2016; Encyclopedia of Life, 2016). The species has a high reproductive potential as it can re-seed easily and propagate vegetatively through its tuberous roots (BioNET-EAFRINET, 2016; Invasive Species South Africa, 2016). M. jalapa is cited as not having a weed potential (PFAF, 2016), but also as an environmental weed, a "sleeper weed" or as a possible noxious weed (BioNET-EAFRINET, 2016; Dave's Garden; 2016). It can escape from gardens into nearby areas and will naturalise in disturbed areas (BioNET-EAFRINET, 2016).

Since the identification of Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China in December 2019, there have been more than 17 million cases of the disease in 216 countries worldwide. Comparisons of prevalence estimates between different communities can inform policy decisions regarding safe travel between countries, help to assess when to implement (or remove) disease control measures and identify the risk of over-burdening healthcare providers. Estimating the true prevalence can, however, be challenging because officially reported figures are likely to be significant underestimates of the true burden of COVID-19 within a community. Previous methods for estimating the prevalence fail to incorporate differences between populations (such as younger populations having higher rates of asymptomatic cases) and so comparisons between, for example, countries, can be misleading. Here, we present an improved methodology for estimating COVID-19 prevalence. We take the reported number of cases and deaths (together with population size) as raw prevalence for the population. We then apply an age-adjustment to this which allows the age-distribution of that population to influence the case-fatality rate and the proportion of asymptomatic cases. Finally, we calculate the likely underreporting factor for the population and use this to adjust our prevalence estimate further. We use our method to estimate the prevalence for 166 countries (or the states of the United States of America, hereafter referred to as US state) where sufficient data were available. Our estimates show that as of the 30th July 2020, the top three countries with the highest estimated prevalence are Brazil (1.26%, 95% CI: 0.96 - 1.37), Kyrgyzstan (1.10%, 95% CI: 0.82 - 1.19) and Suriname (0.58%, 95% CI: 0.44 - 0.63). Brazil is predicted to have the largest proportion of all the current global cases (30.41%, 95%CI: 27.52 - 30.84), followed by the USA (14.52%, 95%CI: 14.26 - 16.34) and India (11.23%, 95%CI: 11.11 - 11.24). Amongst the US states, the highest prevalence is predicted to be in Louisiana (1.07%, 95% CI: 1.02 - 1.12), Florida (0.90%, 95% CI: 0.86 - 0.94) and Mississippi (0.77%, 95% CI: 0.74 - 0.81) whereas amongst European countries, the highest prevalence is predicted to be in Montenegro (0.47%, 95% CI: 0.42 - 0.50), Kosovo (0.35%, 95% CI: 0.29 - 0.37) and Moldova (0.28%, 95% CI: 0.23 - 0.30). Our results suggest that Kyrgyzstan (0.04 tests per predicted case), Brazil (0.04 tests per predicted case) and Suriname (0.29 tests per predicted case) have the highest underreporting out of the countries in the top 25 prevalence. In comparison, Israel (34.19 tests per predicted case), Bahrain (19.82 per predicted case) and Palestine (9.81 tests per predicted case) have the least underreporting. The results of this study may be used to understand the risk between different geographical areas and highlight regions where the prevalence of COVID-19 is increasing most rapidly. The method described is quick and easy to implement. Prevalence estimates should be updated on a regular basis to allow for rapid fluctuations in disease patterns.

This article is devoted to the analysis of legal regulation of marriage in fact in the Russian Federation and the United States. The purpose of this work is due to an increase in the number of marriage in fact and as a consequence the need for legal regulation of these relations. For a comprehensive study the author uses comparative legal method that takes into account the experience of not only Russia, but also foreign states. The author examines the legal regulation of marriage in fact in Russia and the United States; defines the legal norms, which is applied for the regulation of relations between the actual spouses, current Russian legislation and the legislation of the states of the USA. In the issue the researcher comes to the conclusion that neither in Russia, nor in the US states in the regulation of marriage in fact, special marriage and family provisions are not applied. At the same time the factual spouses are under legal protection. In Russia, the legal regulation of the relations developing between the actual spouses, no different from the regulation of corresponding relations of other persons. In some US states the actual spouses have special rights and duties, the scope of which is substantially less than the amount of the rights and duties of legal spouses.

Pachycondyla harpax (Fabricius) is a widespread and conspicuous New World ponerine ant (subfamily Ponerinae). To examine the geographic distribution of P. harpax, I compiled and mapped published and unpublished specimen records from >1500 sites. I documented the earliest known P. harpax records for 28 geographic areas (countries, West Indian islands, and US states), including four for which I found no previously published records: the islands of Guadeloupe, Margarita, and Tobago and the US state of Georgia. Pachycondyla harpax has been recorded from every country in South and Central America except Chile and Uruguay. Pachycondyla harpax is also now known from six West Indian islands: Grenada, Guadeloupe, Jamaica, Margarita, Trinidad, and Tobago. The known continental range of P. harpax appears to be essentially continuous, extending from Rio Grande do Sul, Brazil in the south (31.8°S) to Wood County, Texas in the north (32.8°N), including the continental islands of Margarita, Tobago, and Trinidad. Isolated island populations of P. harpax on Grenada, Guadeloupe, and Jamaica may be exotic, introduced through human commerce. In the US, it is unclear why P. harpax populations are only known from Texas, Louisiana, and Georgia, when there would appear to be suitable habitat for this species all along the Gulf coast of Alabama, Mississippi, and Florida.

Abstract. The current study examines the item and scalar equivalence of an abbreviated school-based universal screener that was cross-culturally translated and adapted from English into German. The instrument was designed to assess student behavior problems that impact classroom learning. Participants were 1,346 K-6 grade students from the US (n = 390, Mage = 9.23, 38.5% female) and Germany (n = 956, Mage = 8.04, 40.1% female). Measurement invariance was tested by multigroup confirmatory factor analysis (CFA) across students from the US and Germany. Results support full scalar invariance between students from the US and Germany (df = 266, χ2 = 790.141, Δχ2 = 6.9, p < .001, CFI = 0.976, ΔCFI = 0.000, RMSEA = 0.052, ΔRMSEA = −0.003) indicating that the factor structure, the factor loadings, and the item thresholds are comparable across samples. This finding implies that a full cross-cultural comparison including latent factor means and structural coefficients between the US and the German version of the abbreviated screener is possible. Therefore, the tool can be used in German schools as well as for cross-cultural research purposes between the US and Germany.

This article examines fundamental questions of monetary policy in the context of challenges to the national security of Russia in connection with the imposition of economic sanctions by the US and the EU. It is proved that the policy of the Russian monetary authorities, particularly the Central Bank, artificially limiting the money supply in the domestic market and pandering to the export of capital, compounds the effects of economic sanctions and plunges the economy into depression. The article presents practical advice on the transition from external to domestic sources of long-term credit with the simultaneous adoption of measures to prevent capital flight.
