Today the world modern practice in the field of road construction widely uses warm asphalt concrete mixes (WMA), which are used in the construction of roads for various purposes and ensure their long service life, increasing the construction season, reducing energy costs, as well as reducing the negative impact on the environment. In the United States and Europe, the use of WMA is growing rapidly and now counts tens of millions of tons. The number of asphalt concrete plants equipped with asphalt mixing plants intended for their production is already about 20% of the total number of asphalt concrete plants. The criteria for selecting the combined technology of WMA production are offered. The proposed project management methodology for the development of automated technological processes of WMA production, which allows to formalize the general and partial tasks of the project, taking into account the different degrees

Early studies show that the COVID-19 pandemic causes the rally-around-the-flag effect and increases the level of nationalism among the voters after the outbreak. However, how long does this boost last? Voters may cognitively withdraw their identification to the beloved country if the pandemic is rampant in where they live as well as when the government fails to address it thoroughly. We conducted a pre-registered MTurk experiment (n = 606) on 20 April 2020, in the United States—3 months after the first confirmed case and weeks after the large-scale lockdown. Results show that US subjects who were primed of the COVID-19 in the United States significantly decreased their level of nationalism, especially among Democrats. In contrast, the priming of “COVID-19 in the world” has no effect. The negative impact of COVID-19 on nationalism could be explained by enough time as people could observe and evaluate the government’s performance after the outbreak through the partisan lens.

The US economy is one of the richest and most diversified economies in the world and keeps its leadership in the global economy for the past 100 years. The United States is a global leader in computer technology, pharmaceuticals and the manufacture of medical, aerospace and military equipment. And although services make up about 80% of GDP, the US remains the second largest producer of industrial goods in the world and is a leader in research and development. President Donald Trump was elected in November 2016, promising a big gap with his predecessor’s regulatory, tax and trade policies. Therefore, the current socio-economic status of the USA and the possible ways of its development in the future are interesting for studying the impact on other economies, in particular, on the Ukrainian economy and the search for new and optimal ways of developing relations between the United States and Ukraine. Key macroeconomic indicators of the US economy in 2011–2018 are analyzed, demonstrating the influence of Donald Tramp’s new policy on changes in the indicators of the economy, the labor market, trade, etc., as well as possible ways of development in the coming years. The review of key macroeconomic indicators gives grounds for classifying the American economy as healthy one. Rates of GDP growth will remain in the range of 2 to 3%. These rates of growth in the world’s largest economy are callable to ensure a substantial increase in the global activity. But uncertainties in the politics may hinder global growth and have clearly negative impact on the investment growth in developed and developing economies.

Based on a wide range of sources, the article analyzes the impact of China's trade and economic relations with the United States. Several periods of interaction between countries after the end of World War II are considered. Special attention is paid to the period of restoration of diplomatic relations since 1979. Based on various sources and historiography, the author analyzes the researchers' points of view on the impact of economic issues on the relations between the two countries. In the course of the research, the author came to the conclusion that an important aspect in the direction of the foreign economic policy of the People’s Republic of China in the first post-war years was the ideological factor. The article presents an analysis of changes in the vector of China's foreign policy in different periods. The main ways of interaction between the United States and China are described, depending on changing foreign policy doctrines. The reforms launched in 1978 provided China with economic growth and a growing prestige on the world stage, which is still present today. The rapprochement between the United States and China after the collapse of the Soviet Union in 1991 brought certain economic benefits for the two countries. However, the aggravation of relations between the countries in the new Millennium provides an opportunity for new assessments of the PRC's position on the world stage. Trump’s coming to power in the United States is regarded as an economic war between the two countries. China's increased investment capacity and technological independence make it an attractive partner for other countries, which in turn has a negative impact on trade with America. The most important thing in this situation is the fact that the globalization of the world economy caused by scientific and technological progress, including the rather close interweaving of the US and Chinese economies, contradicts the national interests of both countries, which are trying to strengthen their positions and role in the world economy. Based on the analyzed material, the author comes to the conclusion that recently the foreign policy relations between China and the United States directly depend on the economic interests of the parties.

Background. Nearly all of the research on sex differences in mass media utilization has been based on samples from the United States and a few other Western countries. Aim. The present study examines sex differences in mass media utilization in four Asian countries (Japan, Malaysia, South Korea, and Singapore). Methods. College students self-reported the frequency with which they accessed the following five mass media outlets: television dramas, televised news and documentaries, music, newspapers and magazines, and the Internet. Results. Two significant sex differences were found when participants from the four countries were considered as a whole: Women watched television dramas more than did men; and in Japan, female students listened to music more than did their male counterparts. Limitations. A wider array of mass media outlets could have been explored. Conclusions. Findings were largely consistent with results from studies conducted elsewhere in the world, particularly regarding sex differences in television drama viewing. A neurohormonal evolutionary explanation is offered for the basic findings.

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.

From the Baltic to the South China Sea, newly assertive authoritarian states sense an opportunity to resurrect old empires or build new ones at America's expense. Hoping that U.S. decline is real, nations such as Russia, Iran, and China are testing Washington's resolve by targeting vulnerable allies at the frontiers of American power. This book explains why the United States needs a new grand strategy that uses strong frontier alliance networks to raise the costs of military aggression in the new century. The book describes the aggressive methods which rival nations are using to test American power in strategically critical regions throughout the world. It shows how rising and revisionist powers are putting pressure on our frontier allies—countries like Poland, Israel, and Taiwan—to gauge our leaders' commitment to upholding the American-led global order. To cope with these dangerous dynamics, nervous U.S. allies are diversifying their national-security “menu cards” by beefing up their militaries or even aligning with their aggressors. The book reveals how numerous would-be great powers use an arsenal of asymmetric techniques to probe and sift American strength across several regions simultaneously, and how rivals and allies alike are learning from America's management of increasingly interlinked global crises to hone effective strategies of their own. The book demonstrates why the United States must strengthen the international order that has provided greater benefits to the world than any in history.

Every child has a right to an education. In the United States, the issue is not necessarily about access to a school but access to a quality education. With strict compulsory education laws, more than 50 million students enrolled in primary and secondary schools, and billions of dollars spent annually on public and private education, American children surely have access to buildings and classrooms. However, because of a complex and competitive system of shared policymaking among national, state, and local governments, not all schools are created equal nor are equal education opportunities available for the poor, minorities, and underprivileged. One manifestation of this inequity is the lack of qualified teachers in many urban and rural schools to teach certain subjects such as science, mathematics, and technology. The purpose of this article is to describe a partnership model between two major institutions (The American Museum of Natural History and The City University of New York) and the program designed to improve the way teachers are trained and children are taught and introduced to the world of science. These two institutions have partnered on various projects over the years to expand educational opportunity especially in the teaching of science. One of the more successful projects is Seminars on Science (SoS), an online teacher education and professional development program, that connects teachers across the United States and around the world to cutting-edge research and provides them with powerful classroom resources. This article provides the institutional perspectives, the challenges and the strategies that fostered this partnership.
