Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985 and 2015, we searched for documents in the ISI Web of Science, Scopus and SciELO databases. A total of 979 works were evaluated from 184 periodicals. The United States is the country with the most publications about aquatic oligochaetes, followed by France, Germany and Italy. Works related to the ecology and ecotoxicology of these organisms are most abundant. Studies carried out in the laboratory are most frequent, consisting of investigations involving bioassays, morphology, genetics and molecular biology. The results also show that spring, cave water bodies and swamps have been studied less than any other aquatic habitat and that countries of the Southern Hemisphere are under-represented in the studies of aquatic oligochaetes. Hence, there is a need for increased efforts to fill in gaps in the knowledge about these oligochaetes.

Introdução: É notável o crescimento na produção de conhecimento na área da psicologia do esporte (PE). O conhecimento produzido pelos pesquisadores ocorre através da publicação de seus trabalhos no formato de artigos em periódicos científicos. Não existe na literatura análises considerando os periódicos específicos da área e suas características. Objetivo: Discutir acerca do cenário atual de periódicos específicos relacionados à PE. Métodos: Trata-se de uma pesquisa documental a respeito dos periódicos de PE. Foram extraídos e analisados dados como país, instituição, editora, língua de publicação, as métricas (JCR - ISI Web of Science, SJR, Citescore e SNIP – Scopus, e índice h5 – Google Scholar), periodicidade, período de publicações e número de artigos publicados em 2018. Resultados: Foram observados 14 periódicos na literatura relacionados diretamente a temática da PE. A maioria dos periódicos (5) é dos Estados Unidos, três da Espanha e três do Reino Unido. Brasil, Itália e Holanda apresentaram um periódico cada. A maioria dos periódicos publica na língua inglesa (13 dos 14). O fator de impacto (JCR) dos periódicos variou de 0,64 a 6,90, cinco periódicos não apresentaram essa métrica em 2018. Neste ano, os periódicos publicaram de 11 até 144 artigos. Conclusão: A partir da análise dos periódicos científicos específicos da PE, verificou-se que os de maior qualidade considerando as métricas analisadas, são dos Estados Unidos e da Europa. No Brasil ressalta-se a necessidade de fortalecimento do periódico específico existente na área, que pode ser realizado a partir da unificação das organizações que atuam na prática profissional e na pesquisa científica em PE. ABSTRACT. Sport psychology research and the specific journals scenario. Background: There is a remarkable growth in the production of knowledge in the field of sports psychology (SP). The knowledge produced by researchers occurs through the publication of their work in the format of articles in scientific journals. There are no analyses in the literature considering the specific journals of the area and their characteristics. Objective: To discuss about the current scenario of specific journals related to SP. Methods: This is a documentary research about the SP journals. The following data were extracted and analyzed: country, institution, publisher, publication language, metrics (JCR - ISI Web of Science, SJR, Citescore and SNIP – Scopus, and index h5 – Google Scholar), periodicity, publication period, and number of articles published in 2018. Results: It was observed 14 journals related to SP. Most of them are from United States, three from Spain and three from United Kingdom. Brazil, Italy and Netherlands showed one journal each. Most of the journals publish in English language (13 of 14). The impact factor ranged from 0.64 to 6.90, and five journals do not show this metric in 2018. In this year, the journals published from 11 to 144 articles. Conclusion: From the analysis of the specific scientific journals of the SP, it was found that the journals with highest quality are from the United States and Europe. In Brazil, there is a need to strengthen the existing specific journal in the area, which can be done by unifying the organizations that work in professional practice and scientific research of SP.

In this article, we present a tool and a method for measuring the psychological and cultural distance between societies and creating a distance scale with any population as the point of comparison. Because psychological data are dominated by samples drawn from Western, educated, industrialized, rich, and democratic (WEIRD) nations, and overwhelmingly, the United States, we focused on distance from the United States. We also present distance from China, the country with the largest population and second largest economy, which is a common cultural comparison. We applied the fixation index ( FST), a meaningful statistic in evolutionary theory, to the World Values Survey of cultural beliefs and behaviors. As the extreme WEIRDness of the literature begins to dissolve, our tool will become more useful for designing, planning, and justifying a wide range of comparative psychological projects. Our code and accompanying online application allow for comparisons between any two countries. Analyses of regional diversity reveal the relative homogeneity of the United States. Cultural distance predicts various psychological outcomes.

Economic crisis, which took place in the years 2008–2009, was one of the biggest cri-ses, which affected the world’s economy. It began in the United States, and then it moved through most countries in the world, especially the highly developed, and the effects of this crisis have been very painful for the entire global economy. It should be stressed that the framework of the economic crisis include the period 2008–2010, although its roots go back to an earlier period than 2008, and its consequences – accord-ing to the authors – will be felt for many years. In the wide range, the financial crisis referred to the economic collapse, caused by making the wrong decisions by the monetary authorities of individual countries, unskilful ac-tions of speculators and recession on the course of business cycle. Undoubtedly it was globalisation which contributed to such state, which has led to a great openness of economies, which in turn resulted in the transfer between all economic phenomena, both the positive and the negative. Moreover, globalisation caused the fact that crisis phenomena are growing strong, more and more noticeable and faster and faster move between individual countries. Trade and financial relations, and (perhaps most importantly) the panic in the markets, are responsible for this process.

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.

The coronavirus disease 2019 (COVID-19) is spreading rapidly all over the world. The transmission dynamics of the COVID-19 pandemic is still unclear, but developing strategies for mitigating the severity of the pandemic is yet a top priority for global public health. In this study, we developed a novel compartmental model, SEIR-CV(susceptible-exposed-infectious-removed with control variables), which not only considers the key characteristics of asymptomatic infection and the effects of seasonal variations, but also incorporates different control measures for multiple transmission routes, so as to accurately predict and effectively control the spread of COVID-19. Based on SEIR-CV, we predicted the COVID-19 epidemic situation in China out of Hubei province and proposed corresponding control strategies. The results showed that the prediction results are highly consistent with the outbreak surveillance data, which proved that the proposed control strategies have achieved sound consequent in the actual epidemic control. Subsequently, we have conducted a rolling prediction for the United States, Brazil, India, five European countries (the United Kingdom, Italy, Spain, Germany, and France), southern hemisphere, northern hemisphere, and the world out of China. The results indicate that control measures and seasonal variations have a great impact on the progress of the COVID-19 pandemic. Our prediction results show that the COVID-19 pandemic is developing more rapidly due to the impact of the cold season in the southern hemisphere countries such as Brazil. While the development of the pandemic should have gradually weakened in the northern hemisphere countries with the arrival of the warm season, instead of still developing rapidly due to the relative loose control measures such as the United States and India. Furthermore, the prediction results illustrate that if keeping the current control measures in the main COVID-19 epidemic countries, the pandemic will not be contained and the situation may eventually turn to group immunization, which would lead to the extremely severe disaster of about 5 billion infections and 300 million deaths globally. However, if China's super stringent control measures were implemented from 15 July, 15 August or 15 September 2020, the total infections would be contained about 15 million, 32 million or 370 million respectively, which indicates that the stringent and timely control measures is critical, and the best window period is before September for eventually overcoming COVID-19.

Osteoporosis is a systemic disease of the bone that affects millions of people and causes burden for both the affected individual and health systems and societies worldwide. Since the 1970s much research has been done in the field of osteoporosis. The number of citations of a paper reflects its influence and importance to the field. Thomson ISI Web of Science database was searched to retrieve a list of the fifty most cited articles related to osteoporosis and its research. The fifty most cited articles in absolute numbers in the field of osteoporosis were cited from 877 to 3056 times (mean1141±537). Most papers were published in the basic science category(n=23). 395 authors contributed; a single paper had between one and 62 authors (mean:10.02±9.9authors). 12 authors (3.04%) contributed between 7 and 4 papers; 340 authors (86.1%) were at least named once. Corresponding authors were from eight countries with most contributions from the United States (n=34, 68%). The majority of papers were published in the 1990s(n=29). The list of 50 most cited papers presents citation classics in the field of osteoporosis and related research.

A lack of uniformity in laws regulating professionals such as auditors and lawyers in relation to defective prospectuses exists across nations around the world. Securities legislation of some jurisdictions clearly imposes criminal liabilities for defective prospectuses on professionals along with directors and promoters of the issuer of securities. But the laws of some other countries are ambiguous in this regard. Such an ambiguity is present in the securities legislation of the United States, Australia and Canada. Their legislation does not categorically name the persons who should be criminally liable for a defective prospectus; nonetheless auditors and lawyers are sometimes caught by virtue of judicial interpretations of those vague legal provisions. Even though they could be on the hook under such interpretations, legislation provides a wide range of defences that facilitate escaping liabilities by offenders at the expense of the integrity of the market. Regarding sanctions, although the term of imprisonment is identical in all these three jurisdictions, pecuniary penalties significantly vary after the recent reforms triggered by some spectacular corporate bankruptcy taking place especially in the U.S. and Australia. Most importantly, the post-Enron reforms explicitly amend the laws governing secondary securities markets, and therefore their application to defective prospectuses is questionable except for the Canadian reforms. If the post-Enron reforms do not really touch the prospectus liability regimes in the U.S. and Australia, it can be said that the lawmakers have ignored their primary securities markets. If this is so, it would be an unwise policy to wait for an Enron-type disaster to occur in the IPO market for stimulus to initiate reforms addressing professional malpractices in the preparation of prospectuses. If not, the law should make it clear before it is too late.

Abstract. There is a wide range of article and literature in agricultural sciences, but only a few review of existing studies has systematically analyzed and visualized the trends in agricultural research. This study reviews agricultural research mainly published in the Scopus and Web of Science databases from 2013 to 2018 with the scientometric analysis. The main hot Research Fronts mainly cover research on plant-gene regulatory networks and genome editing; crop disease and pest control; food nutrition and safety; photosynthesis; plant rhizosphere microbial community; immunity of aquatic animals; and forest tree cultivation. The analysis covers 325 966 scientific research in General Agricultural and Biological Sciences in online tool SciVal (Scopus). Most frequently occurred keywords indexed in the research area are patients, cells, humans. Three subject area were identified with the combination of cluster analysis with VosViewer: „Medicine“, „Biochemistry, Genetic and Molecular Biology“, „Engineering“. Nearly half the papers (49,3 %) were published by the following three countries: the United States, China and the United Kingdom. Russia's contribution to the global ranking is 1,8 %. The most popular journals by average number of publication produced in the United Kingdom. Web of Science data analyzed with a tool InCites. The analysis covers 141 010 papers in categories „Agricultural Economics & Policy“, „Agricultural Engineering“, „Agriculture, Dairy & Animal Science“, „Agriculture, Multidisciplinary“. Сompilation of bibliometric maps allows to identify the commonly used keywords: evidence, pretreatment, cattle, growth. Four research themes were identified with the combination of cluster analysis: „Material Science Multidisciplinary“, „Biochemistry and Molecular Biology“, „Engineering Electrical Electronic“, „Chemistry, Physical“. In the Web of Science, the most cited journals have been taken by the company „Elsiever“. The study revealed that the Scopus is a more developed database on the direction of agriculture. The potential of Russian journals is determined by sampling journals in the RSCI by the number of citations. This review provides an in-depth understanding of existing agricultural trends in this research domain.

AbstractThe COVID-19 pandemic has impacted billions of people around the world. To capture some of these impacts in the United States, we are conducting a nationwide longitudinal survey collecting information about activity and travel-related behaviors and attitudes before, during, and after the COVID-19 pandemic. The survey questions cover a wide range of topics including commuting, daily travel, air travel, working from home, online learning, shopping, and risk perception, along with attitudinal, socioeconomic, and demographic information. The survey is deployed over multiple waves to the same respondents to monitor how behaviors and attitudes evolve over time. Version 1.0 of the survey contains 8,723 responses that are publicly available. This article details the methodology adopted for the collection, cleaning, and processing of the data. In addition, the data are weighted to be representative of national and regional demographics. This survey dataset can aid researchers, policymakers, businesses, and government agencies in understanding both the extent of behavioral shifts and the likelihood that changes in behaviors will persist after COVID-19.
