Dominance hierarchies have been studied for almost 100 years. A science of science approach can help provide high-level insight into how the dynamics of dominance hierarchy research have shifted or been maintained over this long timescale. To summarize these general patterns, I extracted publication metadata using a Google Scholar search of "dominance hierarchy'', resulting in over 26,000 publications. I used text mining approaches to assess patterns in three areas: (1) general patterns in publication frequency and rate, (2) dynamics of term usage, and (3) term co-occurrence in publications across the history of the field. While the overall number of publications per decade continues to rise, the percent growth rate has fallen in recent years, demonstrating that although there is sustained interest in dominance hierarchies, the field is no longer experiencing the explosive growth it showed in earlier decades. Based on term co-occurrence networks and community structure, the different subfields of dominance hierarchy research were most strongly separated early in the field's history while modern research shows more evidence for cohesion and a lack of distinct term community boundaries. These methods provide a general view of the history of research on dominance hierarchies and can be applied to other fields or search terms to gain broad synthetic insight into patterns of interest, especially in fields with large bodies of literature.

Dominance hierarchies have been studied for almost 100 years. The science of science approach used here provides high-level insight into how the dynamics of dominance hierarchy research have shifted over this long timescale. To summarize these patterns, I extracted publication metadata using a Google Scholar search for the phrase ‘dominance hierarchy’, resulting in over 26 000 publications. I used text mining approaches to assess patterns in three areas: (1) general patterns in publication frequency and rate, (2) dynamics of term usage and (3) term co-occurrence in publications across the history of the field. While the overall number of publications per decade continues to rise, the percent growth rate has fallen in recent years, demonstrating that although there is sustained interest in dominance hierarchies, the field is no longer experiencing the explosive growth it showed in earlier decades. Results from title term co-occurrence networks and community structure show that the different subfields of dominance hierarchy research were most strongly separated early in the field’s history while modern research shows more evidence for cohesion and a lack of distinct term community boundaries. These methods provide a general view of the history of research on dominance hierarchies and can be applied to other fields or search terms to gain broad synthetic insight into patterns of interest, especially in fields with large bodies of literature. This article is part of the theme issue ‘The centennial of the pecking order: current state and future prospects for the study of dominance hierarchies’.

Project management, as a subsidiary of social science, is a vast and varied topic of the area of knowledge. In the past decades, many studies have compiled an immense amount of information for theoreticians and practitioners in this field. In this paper, traditional and novel methods of bibliometric analysis are introduced through a survey for analyzing the history of research in project management. This study focuses on the last four decades of publications on project management, from 1980 to 2019. In the survey, the number of publications, the countries of publication, the cooperating relations among those countries, and the top categories of publications are analyzed. The extraction of publication keywords and the investigation of knowledge seeds are also presented. In the survey, the examination of the network of top occurring keywords, keyword clustering, together with the keyword correlation matrix, were used to explore the main trends in project management. A novel indicator, called the ICCO ranking, is presented by using the degree, betweenness and cluster coefficient of the network of keywords. Using this indicator, the potential knowledge seeds in project management may be identified.

Muscari botryoides (L.) Mill. s. l. (Asparagaceae s. l. / Hyacinthaceae s. str.) is a taxonomically complicated species (or a species aggregate) with a high level of intraspecific polymorphism. Since it has been taxonomically established, a large number of taxa of different ranks have been identified for various regions of Europe, such as Muscari lelievrei Boreau, M. motelayi Foucaud – for France, M. transsilvanicum Schur – for Romania, Botryanthus kerneri Marches., Muscari longifolium Rigo – for Italy, M. botryoides subsp. hungaricum Priszter – for Hungary, M. botryoides var. podolicum Zapał., M. carpaticum Racib. and M. pocuticum Zapał. – for Ukraine. The article provides a brief overview of the main publications on intraspecific taxonomy of M. botryoides. A list of selected synonyms (mainly taxa mentioned for the flora of Ukraine) of the species is provided. It is noted that the intraspecific taxonomy of M. botryoides remains unresolved in many aspects.

The research deals with creating a diverse reader image of an intellectual personality of a historian. V.K. Yakunin started his reading career as a student of Dnipropetrovsk State University in the 1960’s. During his studies he constantly visited the scientific library. It was at this time when he first became acquainted with rare and valuable editions on historical subjects. The reading experience of the historian is about 60 years. While writing his Candidate dissertation (1972) and PhD thesis (1990), he worked with a significant number of sources and literature, and he also used interlibrary loan services. He was a high-level bibliographer, he constantly searched and selected carefully new books of political and historical content. V.K.Yakunin began to collect his own library from the late 1960s. The analysis of his reader cards from the departments of scientific literature and fiction shows that scientist V.K. Yakunin paid primary attention to documents, book sources and periodicals. He perfectly knew the works of foreign historical science classics. He was interested in memoir literature. Psychological and art literature was not ignored by the scientist. The historian always turned to classical works and editions of contemporary Ukrainian writers. V. K. Yakunin’s private library totals about 2000 copies in Ukrainian, Russian and German. It has been stored in the Scientific Library since 2017. Each copy of the professor’s book collection received the stamp «Professor V.K. Yakunin’s Library». The chronological limits of the book collection cover the 20th – the beginning of the 21st century. Most publications are books of social and humanitarian directions. He was interested in the history of the 20th century: political history, public opinion, World War II, history of Nazism, the Ukrainian national movement. Memories held a special place in the book collection. Ways of acquisition to the Library: donations and purchasing. The historian was surrounded by books during his life. Thus, the value of the book collection of Professor V.K. Yakunin is in the presence of a large number of publications that give an idea of the state of book publishing in Ukraine and Russia and indicate the high intellectual level of its owner.

Amblyopia is a sensory developmental disorder affecting as many as 4% of children around the world. While clinically identified as a reduction in visual acuity and disrupted binocular function, amblyopia affects many low- and high-level perceptual abilities. Research with nonhuman primate models has provided much needed insight into the natural history of amblyopia, its origins and sensitive periods, and the brain mechanisms that underly this disorder. Amblyopia results from abnormal binocular visual experience and impacts the structure and function of the visual pathways beginning at the level of the primary visual cortex (V1). However, there are multiple instances of abnormalities in areas beyond V1 that are not simply inherited from earlier stages of processing. The full constellation of deficits must be taken into consideration in order to understand the broad impact of amblyopia on visual and visual–motor function. The data generated from studies of animal models of the most common forms of amblyopia have provided indispensable insight into the disorder, which has significantly impacted clinical practice. It is expected that this translational impact will continue as ongoing research into the neural correlates of amblyopia provides guidance for novel therapeutic approaches.

Wanawa Precolonial Africa: An Introduction focuses on the history and culture of the African continent before it was colonized by Europe. Many people still associate Africa only with the history of the transatlantic slave trade and slavery and neglect the fact that this continent has a rich and diverse history. As this book explains, the history of Africa did not start with the transatlantic slave trade, and Africa is not merely a victim of colonialism but an agent of its own history and rich culture. The intention of this book is to highlight and thereby broaden the knowledge of Africa’s historical, economic, cultural and social diversity. This book is a brief introduction in Papiamentu to the history and culture of precolonial Africa, with the aim of stimulating people to dig deeper into this subject themselves. Its purpose is to provide a general view of the continent’s flora and fauna, to illustrate how large and small states rose, developed and sometimes fell over the course of time, and to shed light on historically significant persons, while also mentioning these states in some cases were connected to the transatlantic slave trade. In addition, the book provides insight into the diverse and heterogeneous cultures of the continent. Rose Mary Allen (Curaçao, 1950) is an anthropologist and Extraordinary Professor of the Chair of Culture, Community and History at the University of Curaçao Dr. Moises da Costa Gomez. She has published many books and articles on migration, slavery, music, oral history, the dynamics of identity formation, modern nationalism, and gender issues. She is a recipient of the Boeli van Leeuwen Award and of the 2015 Cola Debrot Award for her contribution to the sciences.

The article aims at presenting an overview of the main concepts in the philosophical thought of Zhang Shenfu, one of the leading intellectuals from Republican China (1912–1949). The study sets out from a brief summary of Zhang’s intellectual achievements, and proceeds by offering a more concise picture of the main influences, developmental stages and finally also central ideas of Zhang’s thought. By offering a general view on the concrete confluences and dissonances between the keystones of Zhang’s philosophy on one side, and its alleged sources in Western and Chinese philosophy on the other, this study further aims at presenting a new insight into the unique characteristics of Zhang’s philosophy. At the same time, by setting the discussion on Zhang’s philosophy in a broader context of contemporary intellectual discourse, the article also endeavours to establish a tentative basis for the future critical analyses and potential revaluations of Zhang Shenfu’s role in intellectual history of modern China.
