In recent years, the accumulated molecular data of Turnip mosaic virus (TuMV) isolates from various hosts originating from different parts of the world considerably helped to understand the genetic complexity and evolutionary history of the virus. In this work, four complete TuMV genomes (HC9, PK1, MS04, MS15) were characterised from naturally infected cultivated and wild-growing Papaver spp., hosts from which only very scarce data were available previously. Phylogenetic analyses showed the affiliation of Slovak Papaver isolates to the world-B and basal-B groups. The PK1 isolate showed a novel intra-lineage recombination pattern, further confirming the important role of recombination in the shaping of TuMV genetic diversity. Biological assays indicated that the intensity of symptoms in experimentally inoculated oilseed poppy are correlated to TuMV accumulation level in leaves. This is the first report of TuMV in poppy plants in Slovakia.

An important problem of religious studies, the history of religion as a branch of knowledge is the periodization process of the development of religious phenomenon. It is precisely here, as in focus, that the question of the essence and meaning of the religious development of the human being of the world, the origin of beliefs and cult, the reasons for the changes in them, the place and role of religion in the social and spiritual process, etc., are converging.

Medardo Rosso (1858–1928) is one of the most original and influential figures in the history of modern art, and this book is the first historically substantiated critical account of his life and work. An innovative sculptor, photographer, and draftsman, Rosso was vital in paving the way for the transition from the academic forms of sculpture that persisted in the nineteenth century to the development of new and experimental forms in the twentieth century. His antimonumental, antiheroic work reflected alienation in the modern experience yet showed deep feeling for interactions between self and other. Rosso's art was transnational: he refused allegiance to a single culture or artistic heritage and declared himself both a citizen of the world and a maker of art without national limits. This book develops a narrative that is an alternative to the dominant Franco-centered perspective on the origin of modern sculpture in which Rodin plays the role of lone heroic innovator. Offering an original way to comprehend Rosso, the book negotiates the competing cultural imperatives of nationalism and internationalism that shaped the European art world at the fin de siècle.

This chapter examines the continuities between the categories of the “national” and the “universal” in the nineteenth century. It construes these categories as interrelated efforts to create a “world” on various scales. The chapter explores the perceived role of music as a world-making medium within these discourses. It argues that the increased exposure to cultural difference and the interpretation of that cultural difference as distant in time and space shaped a conception of “humanity” in terms of a universal history of world cultures. The chapter reexamines those early nineteenth-century thinkers whose work became inextricably linked with the rise of exclusivist notions of nationalism in the late nineteenth century, such as Johann Gottfried Herder and John Stuart Mill. It draws from their respective treatment of music to recover their early commitment to universalizable principles and their view that the “world” is something that must be actively created rather than empirically observed.

AbstractThe use of different sources of evidence has been recommended in order to conduct species delimitation analyses to solve taxonomic issues. In this study, we use a maximum likelihood framework to combine morphological and molecular traits to study the case of Xylodon australis (Hymenochaetales, Basidiomycota) using the locate.yeti function from the phytools R package. Xylodon australis has been considered a single species distributed across Australia, New Zealand and Patagonia. Multi-locus phylogenetic analyses were conducted to unmask the actual diversity under X. australis as well as the kinship relations respect their relatives. To assess the taxonomic position of each clade, locate.yeti function was used to locate in a molecular phylogeny the X. australis type material for which no molecular data was available using morphological continuous traits. Two different species were distinguished under the X. australis name, one from Australia–New Zealand and other from Patagonia. In addition, a close relationship with Xylodon lenis, a species from the South East of Asia, was confirmed for the Patagonian clade. We discuss the implications of our results for the biogeographical history of this genus and we evaluate the potential of this method to be used with historical collections for which molecular data is not available.

Abstract Plato’s invention of the metaphor of carving the world by the joints (Phaedrus 265d–66c) gives him a privileged place in the history of natural kind theory in philosophy and science; he is often understood to present a paradigmatic but antiquated view of natural kinds as possessing eternal, immutable, necessary essences. Yet, I highlight that, as a point of distinction from contemporary views about natural kinds, Plato subscribes to an intelligent-design, teleological framework, in which the natural world is the product of craft and, as a result, is structured such that it is good for it to be that way. In Plato’s Philebus, the character Socrates introduces a method of inquiry whose articulation of natural kinds enables it to confer expert knowledge, such as literacy. My paper contributes to an understanding of Plato’s view of natural kinds by interpreting this method in light of Plato’s teleological conception of nature. I argue that a human inquirer who uses the method identifies kinds with relational essences within a system causally related to the production of some unique craft-object, such as writing. As a result, I recast Plato’s place in the history of philosophy, including Plato’s view of the relation between the kinds according to the natural and social sciences. Whereas some are inclined to separate natural from social kinds, Plato holds the unique view that all naturalness is a social feature of kinds reflecting the role of intelligent agency.

Abstract The Wukan Incident attracted extensive attention both in China and around the world, and has been interpreted from many different perspectives. In both the media and academia, the focus has very much been on the temporal level of the Incident. The political and legal dimensions, as well as the implications of the Incident in terms of human rights have all been pored over. However, what all of these discussions have overlooked is the role played by religious force during the Incident. The village of Wukan has a history of over four hundred years, and is deeply influenced by the religious beliefs of its people. Within both the system of religious beliefs and in everyday life in the village, the divine immortal Zhenxiu Xianweng and the religious rite of casting shengbei have a powerful influence. In times of peace, Xianweng and casting shengbei work to bestow good fortune, wealth and longevity on both the village itself, and the individuals who live there. During the Wukan Incident, they had a harmonizing influence, and helped to unify and protect the people. Looking at the specific roles played by religion throughout the Wukan Incident will not only enable us to develop a more meaningful understanding of the cultural nature and the complexity of the Incident itself, it will also enrich our understanding, on a divine level, of innovations in social management.

ABSTRACT Cucumber mosaic virus (CMV) is an RNA plant virus with a tripartite genome and an extremely broad host range. Previous evolutionary analyses with the coat protein (CP) and 5′ nontranslated region (NTR) of RNA 3 suggested subdivision of the virus into three groups, subgroups IA, IB, and II. In this study 15 strains of CMV whose nucleotide sequences have been determined were used for a complete phylogenetic analysis of the virus. The trees estimated for open reading frames (ORFs) located on the different RNAs were not congruent and did not completely support the subgrouping indicated by the CP ORF, indicating that different RNAs had independent evolutionary histories. This is consistent with a reassortment mechanism playing an important role in the evolution of the virus. The evolutionary trees of the 1a and 3a ORFs were more compact and displayed more branching than did those of the 2a and CP ORFs. This may reflect more rigid host-interactive constraints exerted on the 1a and 3a ORFs. In addition, analysis of the 3′ NTR that is conserved among all RNAs indicated that evolutionary constraints on this region are specific to the RNA component rather than the virus isolate. This indicates that functions other than replication are encoded in the 3′ NTR. Reassortment may have led to the genetic diversity found among CMV strains and contributed to its enormous evolutionary success.

Historians of political thought and international lawyers have both expanded their interest in the formation of the present global order. History, Politics, Law is the first express encounter between the two disciplines, juxtaposing their perspectives on questions of method and substance. The essays throw light on their approaches to the role of politics and the political in the history of the world beyond the single polity. They discuss the contrast between practice and theory as well as the role of conceptual and contextual analyses in both fields. Specific themes raised for both disciplines include statehood, empires and the role of international institutions, as well as the roles of economics, innovation and gender. The result is a vibrant cross-section of contrasts and parallels between the methods and practices of the two disciplines, demonstrating the many ways in which both can learn from each other.

In an effort to fight climate change, many cities try to boost their cycling levels. They often look towards the Dutch for guidance. However, historians have only begun to uncover how and why the Netherlands became the premier cycling country of the world. Why were Dutch cyclists so successful in their fight for a place on the road? Cycling Pathways: The Politics and Governance of Dutch Cycling Infrastructure, 1920-2020 explores the long political struggle that culminated in today’s high cycling levels. Delving into the archives, it uncovers the important role of social movements and shows in detail how these interacted with national, provincial, and urban engineers and policymakers to govern the distribution of road space and construction of cycling infrastructure. It discusses a wide range of topics, ranging from activists to engineering committees, from urban commuters to recreational cyclists and from the early 1900s to today in order to uncover the long and all-but-forgotten history of Dutch cycling governance.
