Since coal resources are located around the world and often far away from where the coal is consumed, transportation is important. The industries that use coal such as power plants, industrial plants, coke plants, and commercial institutions usually prefer different transportation methods. The demand in these industries and the transportation methods they use differ over time. This chapter analyzes the international coal transportation and demand. An analysis for the US coal market and the transportation to industries along with the methods that are used between 2001-2015 are presented. A trend analysis was performed to show the long-term demand for each transportation method in each industry. Such analysis is also useful as it allows observing the coal demand from each industry. Analysis results reveal the change in coal amounts that are transported to each industry using the railroad, truck, and other methods.

AbstractThis paper studies the existence of a world business cycle by examining quarterly and annual comovements in production, prices and interest rates in the three main world economies: Germany, Japan and the US. In accordance with earlier studies, contemporaneous relationships clearly dominate short-term dynamics. The evidence indicates the existence of strong comovements in prices and long-term interest rates, and, to a lesser degree, in GDP and short-term interest rates. They are, however, rather unstable over time.

The article highlights the changes in the global thermal coal market associated with the consequences of the COVID-19 pandemic, examines the dynamics of import volumes by key countries - consumers of thermal coal and export volumes by major exporting countries, as well as price changes in the main international markets. Analysis of changes in the global steam coal market caused by the consequences of the COVID-19 pandemic and a number of other objective factors demonstrates a change in the competitive positions of the largest exporting countries, which may have long-term consequences. In addition, the article examines the continuing trend of dividing the thermal coal market into the high-calorie and low-calorie thermal coal markets, which have multidirectional development prospects.

World growth is expected to remain below trend at 3.1 per cent in 2012 and 3.4 per cent in 2013.The Euro Area is forecast to contract by 0.5 per cent this year and grow only marginally next year with unemployment reaching ‘depression-era’ rates in some periphery economies. The US is likely to grow by 2 per cent in each year.Growth in Brazil, Russia, India and China will be below long-term potential next year, although ‘hard-landings’ will be avoided; the impact on advanced economies will be offset by a large gain in competitiveness.Debt to GDP ratios in OECD countries will, on average, be higher in 2014 than at present.

Recent studies have explored how the US public responded to the March for Science protests that took place around the world on April 22, 2017, as well as why individuals participated in these protests. Yet, little research has examined how participants used social media and other channels to learn, communicate, and form behavioral intentions regarding the movement. In addressing these questions, the present study conceptualizes the March for Science as a “networked protest.” It then analyzes data from two surveys: one distributed through social media in the month preceding the March for Science events, and one conducted at the Washington, DC event. The results suggest that social media—particularly Facebook—played key roles in how respondents learned and communicated about the protest. At the same time, respondents also learned and communicated about it through other channels, including texting, email, and face-to-face conversations. Both social media respondents and in-person respondents reported that their experiences with the March had increased their likelihood of undertaking future online and offline actions. Furthermore, communicating through Facebook and Twitter predicted a range of self-reported effects of March experiences on intentions to undertake future actions, whereas learning through social media largely failed to do so. Thus, some—but not all—social media uses may have encouraged participants to sustain both online and offline engagement. Taken together, the findings carry potential implications for how the March for Science and other networked protests can use social media and other communication forms to mobilize supporters and facilitate long-term engagement.

In 2018, after 25 years of the North America Trade Agreement (NAFTA), the United States requested new rules which, among other requirements, increased the regional con-tent in the production of automotive components and parts traded between the three part-ner countries, United States, Canada and Mexico. Signed by all three countries, the new trade agreement, USMCA, is to go into force in 2022. Nonetheless, after the 2020 Presi-dential election, the new treaty's future is under discussion, and its impact on the automo-tive industry is not entirely defined. Another significant shift in this industry – the acceler-ated rise of electric vehicles – also occurred in 2020: while the COVID-19 pandemic largely halted most plants in the automotive value chain all over the world, at the reopen-ing, the tide is now running against internal combustion engine vehicles, at least in the an-nouncements and in some large investments planned in Europe, Asia and the US. The definition of the pre-pandemic situation is a very helpful starting point for the analysis of the possible repercussions of the technological and geo-political transition, which has been accelerated by the epidemic, on geographical clusters and sectorial special-isations of the main regions and countries. This paper analyses the trade networks emerg-ing in the past 25 years in a new analytical framework. In the economic literature on inter-national trade, the study of the automotive global value chains has been addressed by us-ing network analysis, focusing on the centrality of geographical regions and countries while largely overlooking the contribution of countries' bilateral trading in components and parts as structuring forces of the subnetwork of countries and their specific position in the overall trade network. The paper focuses on such subnetworks as meso-level structures emerging in trade network over the last 25 years. Using the Infomap multilayer clustering algorithm, we are able to identify clusters of countries and their specific trades in the automotive internation-al trade network and to highlight the relative importance of each cluster, the interconnec-tions between them, and the contribution of countries and of components and parts in the clusters. We draw the data from the UN Comtrade database of directed export and import flows of 30 automotive components and parts among 42 countries (accounting for 98% of world trade flows of those items). The paper highlights the changes that occurred over 25 years in the geography of the trade relations, with particular with regard to denser and more hierarchical network gener-ated by Germany’s trade relations within EU countries and by the US preferential trade agreements with Canada and Mexico, and the upsurge of China. With a similar overall va-riety of traded components and parts within the main clusters (dominated respectively by Germany, US and Japan-China), the Infomap multilayer analysis singles out which com-ponents and parts determined the relative positions of countries in the various clusters and the changes over time in the relative positions of countries and their specialisations in mul-tilateral trades. Connections between clusters increase over time, while the relative im-portance of the main clusters and of some individual countries change significantly. The focus on US and Mexico and on Germany and Central Eastern European countries (Czech Republic, Hungary, Poland, Slovakia) will drive the comparative analysis.

China is currently the only member of the UN Security Council that is actively increasing the quality and quantity of its nuclear potential. Exactly how far China is willing to go in developing its nuclear forces remains a subject of discussion. The prevailing view is that China is seeking to implement a limited increase in its nuclear arsenal in order to secure the potential for a guaranteed re taliation in the face of the US continuously improving its missile defense systems. Since late 1990s, the development of air and naval forces of the Chinese People’s Liberation Army (PLA) has been a subject of increased attention both in Asia and in the world at large. Nuclear potential was not perceived as a priority for China’s development of its military power and remained in the background. However, the events of recent years have shown that the world does not quite realize the true scale of China’s efforts in creating strategic nuclear forces. At this point, it can be perceived as a fait accompli that China has managed to implement most of its long-term program for the modernization of its nuclear forces without attracting too much attention from other major countries and, above all, from the world’s sole superpower.

The Sahel has been a region of movement for millennia, as people cope with drought, search for better land, and seek out new economic opportunities. People move from rural to urban areas and from Mali to elsewhere in West Africa. For the people of Dlonguébougou (DBG), migration has become much more significant since 1980. Increasing numbers of people have left the village permanently, and their children will be urban dwellers. As described through interviews, both men and women want to spend some time away from the village, exploring the world and earning some cash. Becoming a long-term migrant is not usually a one-off choice, but a process over time, which leads one to stay away. Migrant earnings are key to purchase of assets and buying personal goods such as a motorbike, clothes, and mobile phones. For some, they say they see no future in bush villages like DBG.

The globalization of jazz was also the globalization of black US popular culture. This essay discloses, and provides a model for, the ambiguous dynamics of popular music migrations and the race politics that frame them. In diasporic destinations, those politics are generated by cultural histories very different from that of the United States, and which also exhibit their own synchronic and diachronic heterogeneities, thus introducing distinctive local complexities. In the context of the black-centered jazz canon, these circumstances have produced regional jazz narratives that are derived from the US model, but with often radically different inflections from place to place, and over time. Apart from documenting the perennial ubiquity of the blackness/jazz nexus, the study identifies a broad historical trajectory, in which the focus shifted from African American blackness to a pan-African model that anticipated the World Music phenomenon.

A review of: Jansen, Bernard J., and Amanda Spink. “How Are We Searching the World Wide Web? A Comparison of Nine Search Engine Transaction Logs.” Information Processing & Management 42.1 (2006): 248-263. Objective – To examine the interactions between users and search engines, and how they have changed over time. Design – Comparative analysis of search engine transaction logs. Setting – Nine major analyses of search engine transaction logs. Subjects – Nine web search engine studies (4 European, 5 American) over a seven-year period, covering the search engines Excite, Fireball, AltaVista, BWIE and AllTheWeb. Methods – The results from individual studies are compared by year of study for percentages of single query sessions, one-term queries, operator (and, or, not, etc.) usage and single result page viewing. As well, the authors group the search queries into eleven different topical categories and compare how the breakdown has changed over time. Main Results – Based on the percentage of single query sessions, it does not appear that the complexity of interactions has changed significantly for either the U.S.-based or the European-based search engines. As well, there was little change observed in the percentage of one-term queries over the years of study for either the U.S.-based or the European-based search engines. Few users (generally less than 20%) use Boolean or other operators in their queries, and these percentages have remained relatively stable. One area of noticeable change is in the percentage of users viewing only one results page, which has increased over the years of study. Based on the studies of the U.S.-based search engines, the topical categories of ‘People, Place or Things’ and ‘Commerce, Travel, Employment or Economy’ are becoming more popular, while the categories of ‘Sex and Pornography’ and ‘Entertainment or Recreation’ are declining. Conclusions – The percentage of users viewing only one results page increased during the years of the study, while the percentages of single query sessions, one-term sessions and operator usage remained stable. The increase in single result page viewing implies that users are tending to view fewer results per web query. There was also a significant difference in the percentage of queries using Boolean operators between the US-based and the European-based search engines. One of the study’s findings was that results from a study of a particular search engine cannot necessarily be applied to all search engines. Finally, web search topics show a trend towards information or commerce searching rather than entertainment.
