"The Apportionment of Human Diversity" (1972) is the most highly cited research article published by geneticist Richard Lewontin in his career. This study's primary result--that most genetic diversity in humans can be accounted for by within-population differences, not between-population differences--along with Lewontin's outspoken, politically-charged interpretations thereof, has become foundational to the scientific and cultural discourse pertaining to human genetic variation. The article has an unusual bibliometric trajectory in that it is much more salient in the bibliographic record today compared to the first 20 years after its publication. Here, we show how the paper's fame was shaped by four factors: 1) citations in influential publications across several disciplines; 2) Lewontin's own popular books and media appearances; 3) the renaissance of population genetics research of the early 1990s; and 4) the serendipitous collision of scientific progress, influential books/papers, and heated controversies in the year 1994. We conclude with an analysis of Twitter data to characterize the communities and conversations that continue to keep this study at the epicenter of discussions about race and genetics, prompting new challenges for scientists who have inherited Lewontin's legacy.

Abstract Background A citation classic is a highly cited work in a field and regarded as an influential contribution to the field’s advancements and literature. Analyzing citation classics and top articles promotes the recognition of research trends within a field. We present the results of the first analysis to identify the 100 most frequently cited research studies on esophageal cancer or esophagogastric junction cancer using the bibliometric analysis method. Method We searched the Web of Science on September 24, 2020. Articles were listed in descending order by the total number of citations, and the top-100 most-cited original articles on esophageal cancer or esophagogastric junction cancer were extracted and evaluated. Results The top-100 citation classics in esophageal cancer were published from 1981 to 2018. A significant increase was found in the number of citation classics from the early 1990s to the late 2000s, which was paralleled by an increase in randomized controlled trials focusing on the clinical treatment of tumors. The medians of the total and annual citations in our analysis were 444.50 (interquartile range [IQR] 346.25-684.50) and 30.08 (IQR 19.10-56.60), respectively. The majority of articles were published in the Journal of Clinical Oncology (n=26), originated in the United States (n=38) and focused on clinical therapies (n=59). The median impact factor of the journals was 27.603 (IQR 9.727-32.956). Conclusion Our analysis provides a historical perspective on the scientific progress of esophageal cancer and contributes to the recognition of important advances in this specialty.

The article presents a scientometric analysis of the development of the carbon nanotechnology (NT) direction for 2000-2015 with the participation of 30 most active countries. It shows shifting the world research center to the Asian region, both on volume and quality indicators. Using the concept of a national research portfolio gives deep characteristics of different countries behavior in the course of scientific rivalry. Due to the strong skewness of the citation distributions, preference is given to the percentile-based indicators, such as: the contribution of a country to the world top-10% (top-1%) of the most highly cited publications, the share of such publications in the country's total output, the highly cited papers index, etc. Relying on them, the author fully discloses the scientific «offensive» of the «newcomer» countries on the «incumbents» ones (e.g. China on the USA, South Korea on Germany, Iran on Russia), the phenomenon of Singapore as an effective producer of highly cited publications on the carbon nanostructures, and international co-authorship in the top-1% segment of the most cited articles. Russia's positions are studied in detail, the main domestic research participants are established, and based on bibliometric criteria the center of scientific excellence in the field of graphene is identified. The paper characterizes the supporting role of a number of national science foundations in the NT carbon direction development using data of WoS. The author used the Science Citation Index Expanded database for the initial bibliographic sampling; information of science foundations of Russia and the USA, as well as patent organizations of Russia (Rospatent) and the world (WIPO) for additional comparison.

Small countries practising science rarely graduate to the level of performing quality research in sophisticated areas. Viewed on this background, an analysis of 130 papers on superconductivity published by Israeli researchers and indexed in Physics Abstracts 1971-1982 reveal that Israel does pretty well in this area. Prolific institutions and authors have been identified as well as journals most often used, highly cited papers, etc. Many of the papers appeared in high impact international journals, with Physical Review B (26), Journal of Low Temperature Physics (11) and Solid State Communications (10) leading the field. Among the five institutions active in the area, Tel Aviv University (68) accounts for more than half of Israel's publication output. Hebrew University (32) and Tech nion Institute of Technology (22) are the other major centres of research in superconductivity. Five of the 130 papers have won more than 20 citations each up to 1982, and 22 papers more than 10 citations. Israeli papers in superconductivity seem to belong to the mainstream literature in the area as seen from their decent citation record, which is better than that of Canada and almost close to that of the USA. Most of these papers are theoretical/computational and about 30% of them are experi mental.

Abstract Scholars argue that the ‘‘science of science’’ studies have to investigate the critical role of exogenous events in the emergence of new research fields. The goal of this study is to analyze and explain the birth and growth of new research fields driven by exogenous event to science, such as COVID-19 (Coronavirus disease 2019) global pandemic crisis. This study here analyzes how the novel research field of COVID-19 emerges, in a comparative analysis with other scientific fields concerning respiratory illnesses (e.g., Chronic Obstructive Pulmonary Disease, COPD and Lung Cancer), to explain factors determining the unique dynamics of science that is generating scientific breakthroughs in a short period of time. The origin and evolution of the research field of COVID-19 reveal that has an acceleration of scientific production equal to a growth of 1.71% daily in 2020, laying the foundations for science advances and a likely paradigm shift in the treatment of infectious diseases with novel mRNA vaccines. Main results are generalized in properties that clarify the dynamics of science and explain the characteristics that generate the origin and evolution of new research fields driven by unforeseen crises with critical implications for technological and social change directed scientific progress of human societies.

General Perspective

A scientometric analysis as part of a Competitive Technology Intelligence methodology was used to determine the main research efforts in 3D bioprinting. Papers from Scopus and Web of Science (WoS) published between 2000 and 2017 were analysed. A network map of the most frequently occurring keywords in these articles was created, and their average publication year (APY) was determined. The analysis focused on the most relevant keywords that occurred at least five times. A total of 1,759 keywords were obtained, and a co-occurrence analysis was developed for APYs with more keywords: 2011–2016. The results indicated that Polylactic Acid (PLA) is the material used most often. Applications mainly focused on bone tissue engineering and regeneration. The most frequently used technique was inkjet printing, and the main cell sources were Mesenchymal Stem Cells (MSC). From a general perspective, ‘Treatment’ and ‘Bioink’ were the most frequent keywords. The former was mainly related to cancer, regenerative medicine, and MSC and the latter, to multicellular spheroid deposition and the use of hydrogels like GelMA (gelatin methacryloyl). This analysis provides insights to stakeholders involved in 3D bioprinting research and development who need to keep abreast of scientific progress in the field.

The time, extent, and genomic effect of the introgressions from archaic humans into ancestors of extant human populations remain some of the most exciting venues of population genetics research in the past decade. Several studies have shown population-specific signatures of introgression events from Neanderthals, Denisovans, and potentially other unknown hominin populations in different human groups. Moreover, it was shown that these introgression events may have contributed to phenotypic variation in extant humans, with biomedical and evolutionary consequences. In this study, we present a comprehensive analysis of the unusually divergent haplotypes in the Eurasian genomes and show that they can be traced back to multiple introgression events. In parallel, we document hundreds of deletion polymorphisms shared with Neanderthals. A locus-specific analysis of one such shared deletion suggests the existence of a direct introgression event from the Altai Neanderthal lineage into the ancestors of extant East Asian populations. Overall, our study is in agreement with the emergent notion that various Neanderthal populations contributed to extant human genetic variation in a population-specific manner.

Background. Lower extremity reconstruction has always been a challenge. Some of the published articles had a major impact on the field but are often not considered as classics because they have fewer citations. We therefore conducted a scientometric analysis of the most cited articles with a focus solely on the lower limb. Methods. A search was conducted on Medline, the Web of Science database, Google Scholar, and Scopus identifying articles relevant to reconstructive surgery of the lower limb. All journals were included with no time frames. Articles relating solely to orthopedics or vascular reconstruction were excluded. The number of citations obtained were then plotted and compared between the different search engines. The mean citation number was calculated by taking into consideration the total number of years since the article’s first year of publication. Articles were then ranked and classified according to their authors, their years of publications, and their countries. They were furthermore categorized and analyzed. Results. Highly cited articles were easily retrieved with Google Scholar, mostly published in Plastic and Reconstructive Surgery (n = 37) and were mainly authored by American Medical Centers (n = 22). Fifty-four percent (54%) of these classic articles discussed the design of new flaps or were anatomical studies. Conclusions. We were not able to find a correlation between the year of citation and the number of citations. The citation pattern of a paper cannot be predicted, but a majority of highly cited article allowed the design of new reconstructive techniques.

The story is a small volume type of prose, compact, easy to read. At the present stage, the reader's interest in the small genre of prose, which can be seen in the Tom-Tom novels, is especially in demand. Therefore, the study of modern stories is relevant. The main purpose of the research article is to identify the features of life phenomena and author's ideas that make up the content of modern stories. The research was based on stories published in the newspaper” Kazakh Adebieti " over the past five years. The life situations that served as the basis for the conversations were grouped depending on the thematic specifics. The author's views on the topics are systematized and defined. One of the main tasks of the writer is to introduce national interest to the work. The modern story reveals the writers ' position on the causes of various changes in society, the market, scientific progress, contradictions in the correlation of political and social events with the system of national values. One of the main tasks of the research is also to differentiate the features of reflecting the reality of life in synchronous conversations that were censored or written on historical, environmental topics about the abuses of the Soviet government to the Kazakh people during the Soviet period. Behavioral changes and the influence of social aspects on human psychology are analyzed from the point of view of human science. The thematic sphere and actual ideas of modern conversations are discursively analyzed.
