AbstractImperfect historical records and complex demographic histories present challenges for reconstructing the history of biological invasions. Here, we combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of Mimulus guttatus from North America to Europe and the Southwest Pacific. By sampling 521 plants from 158 native and introduced populations genotyped at >44,000 loci, we determined that invasive M. guttatus was first likely introduced to the British Isles from the Aleutian Islands (Alaska), followed by admixture from multiple parts of the native range. We hypothesise that populations in the British Isles then served as a bridgehead for vanguard invasions worldwide. Our results emphasise the highly admixed nature of introduced M. guttatus and demonstrate the potential of introduced populations to serve as sources of secondary admixture, producing novel hybrids. Unravelling the history of biological invasions provides a starting point to understand how invasive populations adapt to novel environments.

AbstractHumans are transforming species ranges worldwide. While artificial translocations trigger biological invasions with negative effects on biodiversity, invasions provide exceptional opportunities to generate ecological and evolutionary hypotheses. Unfortunately, imperfect historical records and exceedingly complex demographic histories present challenges for the reconstruction of invasion histories. Here we combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of yellow monkeyflowers (Mimulus guttatus) from North America to Europe and the Southwest Pacific. By sampling 521 plants from 158 native and introduced populations genotyped at >44,000 loci, we determined that invasive North American M. guttatus was first likely introduced to the British Isles from the Aleutian Islands (Alaska), followed by rapid admixture from multiple parts of the native range. Populations in the British Isles then appear to have served as a bridgehead for vanguard invasions worldwide into the rest of Europe, New Zealand and eastern North America. Our results emphasise the highly admixed nature of introduced M. guttatus and demonstrate the potential of introduced populations to serve as sources of secondary admixture, producing novel hybrids. Unravelling the history of biological invasions provides a starting point to understand how invasive populations adapt to novel environments.

This brief response to Will Davies clarifies and expands a number of the core arguments of the article ‘The Emergence of Neoliberalism: Thinking through and Beyond Michel Foucault’s Lectures on Biopolitics’ (published in TCS 31(4): 3–27). It is argued that it is a mistake to treat Foucault as a neoliberal because his lectures on biopolitics centred on the emergence of different trajectories of neoliberal reason. Instead, Foucault’s genealogy of neoliberalism can be read as a critical history, one that is partial and incomplete but which nonetheless can be used as a starting point to think historically and critically about neoliberalism. It is suggested that a more nuanced history of neoliberalism, however, can be developed by paying closer attention to the complex relationship between neoliberal reason and the earlier liberal ideas of the 19th century – in particular those of John Stuart Mill. Finally, a claim is made for the value of historical analysis for understanding and responding to the challenges of the post-crisis present, to a situation in which neoliberal ideas appear to have a near-hegemonic grip over popular politics and discourse.

<p><strong>Resumo:</strong> O artigo tem como objetivo apresentar a análise histórica das principais legislações federais brasileiras que regulamentaram e regulamentam a relação do homem com o território e o meio ambiente que o integra. Entende-se que referida investigação possibilita aprimorar o conhecimento do processo de construção do Direito e das Políticas Ambientais no Brasil. A partir da concepção histórica desse processo de desenvolvimento da legislação ambiental brasileira, como um produto provisório e que se encontra em permanente transformação, conforme os objetivos do Estado e da sociedade em cada período, abre-se a possibilidade para diagnósticos das origens normativas, espaciais, sociais, econômicas e ambientais que permeiam o processo legislativo, bem como propor alternativas para maior efetividade dos objetivos jurídico-institucionais dos comandos normativos analisados. Sendo, portanto, a leitura histórica da formação da legislação ambiental brasileira utilizada como ponto de partida para se pensar e propor alternativas no sentido de aprimorar a relação presente e futura do homem com o território.</p><p><strong>Palavras chave:</strong> Direito ambiental; História da Legislação Ambiental; Política ambiental.</p><p><strong>Abstract:</strong> The article aims to present a historical analysis of the main Brazilian federal laws that regulated and regulate man's relationship with the territory and the environment that it integrates. It is understood that such research enables to improve the knowledge of the construction process of the Law and Environmental Policies in Brazil. From the conception of this historical development of the Brazilian environmental legislation process as an interim product that is constantly changing, according to the aims State and society in each period, it opens the possibility for diagnosis of normative sources, spatial social, economic and environmental factors that permeate the legislative process, as well as to propose alternatives for greater effectiveness of legal and institutional goals of normative commands analyzed.

AbstractUnlike other European countries, the human population genetics and demographic history of Metropolitan France is surprisingly understudied. In this work, we combined newly genotyped samples from various zones in France with publicly available data and applied both allele frequency and haplotype-based methods in order to describe the internal structure of this country, by using genome-wide single nucleotide polymorphism (SNP) array genotypes. We found out that French Basques are genetically distinct from all other populations in the Hexagone and that the populations from southwest France (namely the Gascony region) share a large proportion of their ancestry with Basques. Otherwise, the genetic makeup of the French population is relatively homogeneous and mostly related to Southern and Central European groups. However, a fine-grained, haplotype-based analysis revealed that Bretons slightly separated from the rest of the groups, due mostly to gene flow from the British Isles in a time frame that coincides both historically attested Celtic population movements to this area between the 3th and the 9th centuries CE, but also with a more ancient genetic continuity between Brittany and the British Isles related to the shared drift with hunter-gatherer populations. Haplotype-based methods also unveiled subtle internal structures and connections with the surrounding modern populations, particularly in the periphery of the Hexagone.

The introduction substantiates the need to address the ethic foundations of human life in connection with the discussions on the search for a way out of the modern civilization of the systemic crisis. Materials and Methods. The object and subject of research are indicated. Based on this, it is given the argumentation for the choice of research methods, which are the method of studying primary sources and comparative historical analysis. Results. A number of preliminary observations are made, which indicate the peculiarities of the study of the problem under consideration. It is indicated the difference of approaches to understanding the history of mankind in the Old and New Testaments of the Christian’s Holy Scripture and in the Koran. As a starting point of comparative historical analysis, the ethic content of the historical concept of the Holy books is highlighted, it is noted that all of them are united by the idea of human sinfulness and the inevitability of punishment for sins. It is given the analysis of the ethic content of the historical concepts of the Old and New Testaments based on the fundamental ideas that determine the content of history of God’s nation of Israel and the Great Commandment. In relation to the Old Testament, the author analyzes the contradictory influence of the idea of God’s nation on the formation of ethics. The analysis of the moral content of the historical concept of the Koran is given based on the recognition of the importance of the prophets in human history; the main plot lines associated with the moral content of this activity are indicated. Discussion and Conclusion. The author substantiates the importance of understanding the historical concept of the sacred books for modern civilization and shows the importance of affirming in interpersonal relations the highest moral principles that form a respectful attitude to a human being.

AbstractOver the last few years a distinct shift has occurred within the thought of liberation theology’s most famous proponent, Gustavo Gutiérrez. Specifically, Gutiérrez has ventured into mysticism. With this movement a fascinating question can be posed: Does the incorporation of mysticism open up a door for dialogue with Latin America’s other popular theology, Pentecostalism? Conversely, should Pentecostalism reflexively understand itself historically and theologically as a liberating movement of the poor? Placed together, an emphasis on praxis seems to reveal, at minimum, a common starting point. The methodology of the paper incorporates a detailed historical analysis of Gutiérrez’s position on mysticism and moves to the conclusion that the shift in emphasis opens the door, albeit a small crack, to one of the most exciting opportunities to occur within the history of Christianity: the marriage of Pentecostal spirituality with liberating social action.

Twenty nine items of correspondence from the mid-1950s discovered recently in the archives of the University Marine Biological Station Millport, and others made available by one of the illustrators and a referee, shed unique light on the publishing history of Collins pocket guide to the sea shore. This handbook, generally regarded as a classic of its genre, marked a huge step forwards in 1958; providing generations of students with an authoritative, concise, affordable, well illustrated text with which to identify common organisms found between the tidemarks from around the coasts of the British Isles. The crucial role played by a select band of illustrators in making this publication the success it eventually became, is highlighted herein. The difficulties of accomplishing this production within commercial strictures, and generally as a sideline to the main employment of the participants, are revealed. Such stresses were not helped by changing demands on the illustrators made by the authors and by the publishers.

H. Lawrence Freeman's “Negro Jazz Grand Opera,” Voodoo, was premiered in 1928 in Manhattan's Broadway district. Its reception bespoke competing, racially charged values that underpinned the idea of the “modern” in the 1920s. The white press critiqued the opera for its allegedly anxiety-ridden indebtedness to nineteenth-century European conventions, while the black press hailed it as the pathbreaking work of a “pioneer composer.” Taking the reception history of Voodoo as a starting point, this article shows how Freeman's lifelong project, the creation of what he would call “Negro Grand Opera,” mediated between disparate and sometimes apparently irreconcilable figurations of the modern that spanned the late nineteenth century through the interwar years: Wagnerism, uplift ideology, primitivism, and popular music (including, but not limited to, jazz). I focus on Freeman's inheritance of a worldview that could be called progressivist, evolutionist, or, to borrow a term from Wilson Moses, civilizationist. I then trace the complex relationship between this mode of imagining modernity and subsequent versions of modernism that Freeman engaged with during the first decades of the twentieth century. Through readings of Freeman's aesthetic manifestos and his stylistically syncretic musical corpus I show how ideas about race inflected the process by which the qualitatively modern slips out of joint with temporal modernity. The most substantial musical analysis examines leitmotivic transformations that play out across Freeman's jazz opera American Romance (1924–29): lions become subways; Mississippi becomes New York; and jazz, like modernity itself, keeps metamorphosing. A concluding section considers a broader set of questions concerning the historiography of modernism and modernity.

The article has as its object the elucidation of the history of the Vyshnivetsky Castle Library, definition of the content of its fund, its historical and cultural significance, correlation of the founder of the Library Mychailo Servaty Vyshnivetsky with the Book.The Vyshnivetsky Castle Library was formed in the Ukrainian historical region of Volyn’, in the Vyshnivets town – “family nest” of the old Ukrainian noble family of the Vyshnivetskies under the “Korybut” coat of arm. The founder of the Library was Prince Mychailo Servaty Vyshnivetsky (1680–1744) – Grand Hetman and Grand Chancellor of the Grand Duchy of Lithuania, Vilno Voievoda. He was a politician, an erudite and great bibliophile. In the 30th–40th of the 18th century the main Prince’s residence Vyshnivets became an important centre of magnate’s culture in Rich Pospolyta. M. S. Vyshnivetsky’s contemporaries from the noble class and clergy knew quite well about his library and really appreciated it. According to historical documents 5 periods are defined in the Library’s history. In the historical sources the first place is occupied by old-printed books of Library collection and 7 Library manuscript catalogues dating from 1745 up to the 1835 which give information about quantity and topical structures of Library collection.The Library is a historical and cultural symbol of the Enlightenment epoch. The Enlightenment and those particular concepts and cultural images pertaining to that epoch had their effect on the formation of Library’s fund. Its main features are as follow: comprehensive nature of the stock, predominance of French eighteenth century editions, presence of academic books and editions on orientalistics as well as works of the ideologues of the Enlightenment and new kinds of literature, which generated as a result of this movement – encyclopaedias, encyclopaedian dictionaries, almanacs, etc. Besides the universal nature of its stock books on history, social and political thought, fiction were dominating.The reconstruction of the history of Vyshnivetsky’s Library, the historical analysis of the provenances in its editions give us better understanding of the personality of its owners and in some cases their philanthropic activities, and a better ability to identify the role of this Library in the culture life of society in a certain epoch.
