Hydrogen produced from renewable energy has the potential to decarbonize parts of the transport sector and many other industries. For a sustainable replacement of fossil energy carriers, both the environmental and economic performance of its production are important. Here, the solar thermochemical hydrogen pathway is characterized with a techno-economic and life-cycle analysis. Assuming a further increase of conversion efficiency and a reduction of investment costs, it is found that hydrogen can be produced in the United States of America at costs of 2.1–3.2 EUR/kg (2.4–3.6 USD/kg) at specific greenhouse gas emissions of 1.4 kg CO2-eq/kg. A geographical potential analysis shows that a maximum of 8.4 × 1011 kg per year can be produced, which corresponds to about twelve times the current global and about 80 times the current US hydrogen production. The best locations are found in the Southwest of the US, which have a high solar irradiation and short distances to the sea, which is beneficial for access to desalinated water. Unlike for petrochemical products, the transport of hydrogen could potentially present an obstacle in terms of cost and emissions under unfavorable circumstances. Given a large-scale deployment, low-cost transport seems, however, feasible.

The national agricultural potential is driven by its current state and agricultural structure development. To date, Ukraine is a leader among the major suppliers of agri-food products to the European Union. However, domestic agriculture sector is still facing a critical need for effective reforms, including its organizational structure, where the key element is the creation of transparent procurement and distribution infrastructure through implementation of the cooperatives paradigm and their further integration with trade as well as processing and food industry enterprises. So far globally, the idea of cooperation has long been translated in a clear economic and legal framework which effectively operates as association of small and medium-sized producers through the creation of individual affluent agricultural business entities – the cooperatives. The United States of America demonstrates best practices in their successful creation and functioning. Given the particularly strong large scale international partnership relations between Ukraine and the US in a number of  economic and social areas, including assistance in boosting cooperative movement, an emphasis is put towards the need to provide insights and suggest a rationale for further development of cooperatives in Ukraine along with enhancing the process management effectiveness based on successful good practice and advancements in the US agribusiness that underpinned the research agenda of this article.  The research findings have revealed that the cooperation of the Ukrainian agriculture enterprises leaves much room for improvement. The number of newly created cooperatives demonstrates slow dynamics; the legislative framework lacks consistency and is inadequate to address the burning issues. The study has identified the key barriers that hamper further development of domestic agricultural cooperation along with discussing the benefits, best practices of implementation, types and specific features of the cooperative form of doing business in the USA. Major challenges in the domestic agricultural cooperation development at macro- and microlevels have been observed and evaluated together with suggesting actions to tackle them. In particular, pathways to enhance the performance of agricultural cooperatives through the transition to more effective process management are proposed.

2018 marks the 100th anniversary of the proclamation of Ukrainian independence. OnJanuary 22, 1918, the Ukrainian People’s Republic proclaimed its independence by adopting the IV Universal of the Ukrainian Central Rada, although this significant event was «wiped out» from the public consciousness on the territory of Ukraine during the years of the Soviet totalitarian regime. At the same time, January 22 was a crucial event for the Ukrainian diaspora in the USA. This article examines how American Ukrainians interacted with the USA Government institutions regarding the celebration and recognition of the Ukrainian Independence day on January 22. The attention is focused on the activities of ethnic Ukrainians in the United States, directed at the organization of the special celebration of the Ukrainian Independence anniversaries in the US Congress and cities. Drawing from the diaspora press and Congressional Records, this article argues that many members of Congress participated in the observed celebration and expressed kind feelings to the Ukrainian people, recognised their fight for freedom, during the House of Representatives and Senate sessions. Several Congressmen submitted the resolutions in the US Congress urging the President of United States to designate January 22 as «Ukrainian lndependence Day». January 22 was proclaimed Ukrainian Day by the governors of fifteen States and mayors of many cities. Keywords: January 22, Ukrainian independence day, Ukrainian diaspora, USA, interaction, Congress

Despite an impressive rise in school enrolment rates over the past few decades, there are concerns about growing inequality of educational opportunity in China. In this article, we examine the level and trend of educational mobility in China, and compare them to the situation in Germany, the Netherlands, the UK and the USA. Educational mobility is defined as the association between parents’ and children’s educational attainment. We show that China’s economic boom has been accompanied by a large decline in relative educational mobility chances, as measured by odds ratios. To elaborate, relative rates of educational mobility in China were, by international standards, quite high for those who grew up under state socialism. For the most recent cohorts, however, educational mobility rates have dropped to levels that are comparable to those of European countries, although they are still higher than the US level.

The article analyzes the prospects for US-North Korean and inter-Korean relations, taking into account the completed policy review of the new US administration towards the Democratic People's Republic of Korea (DPRK), as well as the results of the President of the Republic of Korea Moon Jae-in’s trip to Washington in May 2021 and his talks with US President Joe Biden. It is concluded that the “new" course proposed by the United States in relation to the DPRK will not lead to a solution to the nuclear problem of the Korean Peninsula and will interfere with the normalization of inter-Korean relations. During his visit to the US President Moon failed to obtain the US consent on ROK more “independent policy” toward North Korea. In spite of lavish investments into US economy and other concessions, Seoul was forced to promise to coordinate his approaches to the DPRK with US and Japan and support US position on Taiwan straits and South China Sea. The author argues that in the current conditions, the introduction of a regime of arms limitation and arms control in Korea should be a necessary stage on the way to complete denuclearization of the peninsula. The transition to a such method of the settlement of the nuclear problem could lead to the resumption of the negotiation process, mutual concessions, including reductions in the level of military-political confrontation, partial or large-scale lifting of economic sanctions in exchange for North Korea's restrictions of its nuclear weapon and missile systems.

The last five years defined an alternative course in the US foreign policy. Obama's reelection caused staff transfers which notably influenced the course. This comprehensive process is based on tremendous work conducted by the Administration of Barak Obama, in particular by John Kerry, who was appointed as a Secretary of State in 2013. His personality plays a significant role in American domestic and foreign policy interrelation. Adoption or rejection of the bills, which are well-known today, depended in large on a range of circumstances, such as personality, life journey and political leader career of the today's Secretary of State. John Kerry’s professional life is mainly associated with domestic policy; nevertheless, he has always been interested in foreign relations and national security issues. Those concerns generally included: non-proliferation, US security, ecological problems, fight against terrorism. The article is intended to highlight Kerry’s efforts in each of these fields, showing not only his actions, but also difficult process of adoption or banning bills in the USA. The author tried to display the whole complicated decision-making process among different parties, businessmen and politicians, law and money clashes. The results of many former endeavors can be seen today, in the modern US policy. Based on assumptions about Secretary of State’s beliefs, certain road map can be predicted. In conclusion, the article offers several courses, where the United States are likely to be most active during the next few years. It can be judged exactly which way some current political issues will develop, how the US foreign policy will be shaped by today's decision-makers in the White House.

Abstract. Our understanding of the natural variability of hydroclimate before the instrumental period (ca. 1900 in the United States; US) is largely dependent on tree-ring-based reconstructions. Large-scale soil moisture reconstructions from a network of tree-ring chronologies have greatly improved our understanding of the spatial and temporal variability in hydroclimate conditions, particularly extremes of both drought and pluvial (wet) events. However, certain regions within these large-scale reconstructions in the US have a sparse network of tree-ring chronologies. Further, several chronologies were collected in the 1980s and 1990s, thus our understanding of the sensitivity of radial growth to soil moisture in the US is based on a period that experienced multiple extremely severe droughts and neglects the impacts of recent, rapid global change. In this study, we expanded the tree-ring network of the Ohio River Valley in the US, a region with sparse coverage. We used a total of 72 chronologies across 15 species to examine how increasing the density of the tree-ring network influences the representation of reconstructing the Palmer Meteorological Drought Index (PMDI). Further, we tested how the sampling date influenced the reconstruction models by creating reconstructions that ended in the year 1980 and compared them to reconstructions ending in 2010 from the same chronologies. We found that increasing the density of the tree-ring network resulted in reconstructed values that better matched the spatial variability of instrumentally recorded droughts and to a lesser extent, pluvials. By sampling tree in 2010 compared to 1980, the sensitivity of tree rings to PMDI decreased in the southern portion of our region where severe drought conditions have been absent over recent decades. We emphasize the need of building a high-density tree-ring network to better represent the spatial variability of past droughts and pluvials. Further, chronologies on the International Tree-Ring Data Bank need updating regularly to better understand how the sensitivity of tree rings to climate may vary through time.

Pakistan, since 1947 remains under the umbrella of US, as a result, relations of Pakistan were not smooth with anti US states including USSR. The US was to increase its role in the region in order to make secure the largest petroleum reserves in the Persian Gulf. Pakistan’s alignment with the western world was mainly to counter possible Indian aggression, not to lessen the Soviet influence in the region, but the approach was more or less thwarting Soviet interests in the region. Over 3 million Afghan refugees had travelled to Pakistan in the 1st year of Soviet intervention in Afghanistan. The main objective of the USA during the initial stages of the Soviet invasion of Afghanistan was primarily to ensure that the Soviet exercise would be a costly one. The United States of America supported Afghan militants with the help of Pakistan to organize them against the USSR. A general perception is that US did not want to be directly involved to thwart the Soviet invasion; rather USA handed over the operational aspect of the program to the Pakistan. The Pakistan was in charge of providing the funds and weapons to the mujahedin and setting up training camps. The US remained indecisive over the next course of action in Afghanistan and the Pakistan took the opportunity to carry out its own agenda in Afghanistan to promote their national interests.

The article is devoted to the antimonopoly regulation of IT giants` activities. The author presents an overview of the main trends in foreign and Russian legislation in this area. The problems the antimonopoly regulation of digital markets faces are the following: the complexity of determining the criteria for the dominant position of economic entities in the digital economy and the criteria for assessing the economic concentration in the commodity digital markets; the identification and suppression of cartels; the relationship between competition law and intellectual property rights in the digital age. Some aspects of these problems are considered through the prism of the main trends in the antimonopoly policy in the United States, the European Union, the United Kingdom and Russia. The investigation findings of the USA House of Representatives Antitrust Subcommittee against Apple, Google, Amazon and Facebook are presented. The author justifies the need to separate them, which requires the adoption of appropriate amendments to the antimonopoly legislation. The article analyzes the draft law of the European Commission on the regulation of digital markets – Digital Markets Act, reveals the criteria for classifying IT companies as «gatekeepers», and notes the specific approaches to antimonopoly regulation in the UK and the US. The article describes the concepts «digital platform» and «network effects», presented in the «fifth antimonopoly package of amendments», developed in 2018 by the Federal Antimonopoly Service of the Russian Federation, and gives an overview of the comments of the Ministry of Economic Development regarding these concepts wording in the text of the draft law, which formed the basis for the negative conclusion of the regulator. It is concluded that in the context of the digital markets’ globalization, there is a need for the international legal nature antitrust norms formation, since regional legislation obviously cannot cope with the monopolistic activities of IT giants.

Censuses of population and housing in the United States are of particular interest to experts in many disciplines – in addition to statisticians, also to demographers, political scientists, sociologists, historians, and even psychologists and anthropologists. This is so not only because of the long history of US censuses (the first census in the US was carried out in 1790) or methodological innovations, but due to immigration responsible for the dynamic population growth, and to the specific purpose of the census, which is ensuring the proportional (according to the numer of inhabitants) distribution of seats in the lower chamber of Congress and federal funds (apportionment), guaranteed by the US Constitution. The heterogeneity of the American society, both in the racial-ethnic and religious-cultural sense, in addition to the above considerations, raise questions about the purposes of those changes and directions for improvement in subsequent censuses. The aim of the article is to present the problems and challenges related to censuses in the USA. The paper focuses on methodological and operational solutions that can be implemented thanks to several improvements, including the progress in the fields of statistics and technology. The paper also discusses the issues of credibility of the census data, based on the example of immigration from Poland and the Polish diaspora in the USA.
