Late Pleistocene climate change and the global expansion of anatomically modern humans

The extent to which past climate change has dictated the pattern and timing of the out-of-Africa expansion by anatomically modern humans is currently unclear [Stewart JR, Stringer CB (2012) Science 335:1317–1321]. In particular, the incompleteness of the fossil record makes it difficult to quantify the effect of climate. Here, we take a different approach to this problem; rather than relying on the appearance of fossils or archaeological evidence to determine arrival times in different parts of the world, we use patterns of genetic variation in modern human populations to determine the plausibility of past demographic parameters. We develop a spatially explicit model of the expansion of anatomically modern humans and use climate reconstructions over the past 120 ky based on the Hadley Centre global climate model HadCM3 to quantify the possible effects of climate on human demography. The combinations of demographic parameters compatible with the current genetic makeup of worldwide populations indicate a clear effect of climate on past population densities. Our estimates of this effect, based on population genetics, capture the observed relationship between current climate and population density in modern hunter–gatherers worldwide, providing supporting evidence for the realism of our approach. Furthermore, although we did not use any archaeological and anthropological data to inform the model, the arrival times in different continents predicted by our model are also broadly consistent with the fossil and archaeological records. Our framework provides the most accurate spatiotemporal reconstruction of human demographic history available at present and will allow for a greater integration of genetic and archaeological evidence.

Reflexive stasis, scale reversal and the myth of modern cinema

This chapter looks at three films whose Portuguese urban settings offer a privileged ground for the re-evaluation of the classical-modern-postmodern categorisation with regard to cinema. They are The State of Things (Wim Wenders, 1982), Foreign Land (Walter Salles and Daniela Thomas, 1995) and Mysteries of Lisbon (Raúl Ruiz, 2010). In them, the city is the place where characters lose their bearings, names, identities, and where vicious circles, mirrors, replicas and mise-en-abyme bring the vertiginous movement that had characterised the modernist city of 1920s cinema to a halt. Curiously, too, it is the place where so-called postmodern aesthetics finally finds an ideal home in self-ironical tales that expose the film medium’s narrative shortcomings. Intermedial devices, whether Polaroid stills or a cardboard cut-out theatre, are then resorted to in order to turn a larger-than-life reality into framed, manageable narrative miniatures. The scaled-down real, however, turns out to be a disappointing simulacrum, a memory ersatz that unveils the illusory character of cosmopolitan teleology. In my approach, I start by examining the intertwined and transnational genesis of these films that resulted in three correlated visions of the end of history and of storytelling, typical of postmodern aesthetics. I move on to consider intermedia miniaturism as an attempt to stop time within movement, an equation that inevitably brings to mind the Deleuzian movement-time binary, which I revisit in an attempt to disentangle it from the classical-modern opposition. I conclude by proposing reflexive stasis and scale reversal as the common denominator across all modern projects, hence, perhaps, a more advantageous model than modernity to signify artistic and political values.

'Nature concocts & expels': the agents and processes of recovery from disease in Early Modern England

The ‘golden saying’ in early modern medicine was ‘Nature is the healer of disease’. This article uncovers the meaning and significance of this forgotten axiom by investigating perceptions of the agents and physiological processes of recovery from illness in England, c.1580-1720. Drawing on sources such as medical texts and diaries, it shows that doctors and laypeople attributed recovery to three agents – God, Nature, and the practitioner. While scholars are familiar with the roles of providence and medicine, the vital agency of Nature has been overlooked. In theory, the agents operated in a hierarchy: Nature was ‘God’s instrument’, and the physician, ‘Nature’s servant’; but in practice the power balance was more ambivalent. Nature was depicted both as a housewife who cooked and cleaned the humours, and as a warrior, who defeated the disease. Through exploring these complex dynamics, the article sheds fresh light on concepts of gender, disease, and bodies.

Children’s physic: medical perceptions and treatment of sick children in early modern England, c. 1580-1720

Historians of medicine, childhood, and paediatrics, have often assumed that early modern doctors neither treated children, nor adapted their medicines to suit the peculiar temperaments of the young. Through an examination of medical textbooks and doctors’ casebooks, this article refutes these assumptions. It argues that medical authors and practising doctors regularly treated children, and were careful to tailor their remedies to complement the distinctive constitutions of children. Thus, this article proposes that a concept of ‘children’s physic’ existed in early modern England: this term refers to the notion that children were physiologically distinct, requiring special medical care. Children’s physic was rooted in the ancient traditions of Hippocratic and Galenic medicine: it was the child’s humoral makeup that underpinned all medical ideas about children’s bodies, minds, diseases, and treatments. Children abounded in the humour blood, which made them humid and weak, and in need of medicines of a particularly gentle nature.

“Very sore nights and days”: the child’s experience of illness in early modern England, c. 1580-1720

Sick children were ubiquitous in early modern England, and yet they have received very little attention from historians. Taking the elusive perspective of the child, this article explores the physical, emotional, and spiritual experience of illness in England between approximately 1580 and 1720. What was it like being ill and suffering pain? How did the young respond emotionally to the anticipation of death? It is argued that children’s experiences were characterised by profound ambivalence: illness could be terrifying and distressing, but also a source of emotional and spiritual fulfilment and joy. This interpretation challenges the common assumption amongst medical historians that the experiences of early modern patients were utterly miserable. It also sheds light on children’s emotional feelings for their parents, a subject often overlooked in the historiography of childhood. The primary sources used in this article include diaries, autobiographies, letters, the biographies of pious children, printed possession cases, doctors’ casebooks, and theological treatises concerning the afterlife.

NATO and the environment: the committee on the challenges of modern society

Launched with considerable fanfare in 1969, the Committee on the Challenges of Modern Society (CCMS) was supposed to bring new life to NATO by both re-energising public support and engaging with a variety of themes, issues and partners well beyond the alliance’s traditional scope. The first aim of this article is to go beyond the careful media operation that surrounded the launch of the CCMS and to examine the scepticism and resistance of some European partners, particularly the British. The second aim is to demonstrate that NATO started to think in terms of crisis management, disaster relief and environmental disasters well before 1989. The sheer military strength of the alliance and of its partners did remain central – and notably came back to the forefront in 1979 – but the alliance did start to see itself as a geopolitical player and to consider engagement beyond its strictly defined geographical area as early as 1969.

Genomic evidence for the Pleistocene and recent population history of Native Americans

How and when the Americas were populated remains contentious. Using ancient and modern genome-wide data, we found that the ancestors of all present-day Native Americans, including Athabascans and Amerindians, entered the Americas as a single migration wave from Siberia no earlier than 23 thousand years ago (ka) and after no more than an 8000-year isolation period in Beringia. After their arrival to the Americas, ancestral Native Americans diversified into two basal genetic branches around 13 ka, one that is now dispersed across North and South America and the other restricted to North America. Subsequent gene flow resulted in some Native Americans sharing ancestry with present-day East Asians (including Siberians) and, more distantly, Australo-Melanesians. Putative “Paleoamerican” relict populations, including the historical Mexican Pericúes and South American Fuego-Patagonians, are not directly related to modern Australo-Melanesians as suggested by the Paleoamerican Model.

The Sick Child in Early Modern England, 1580-1720

The Sick Child in Early Modern England is a powerful exploration of the treatment, perception, and experience of illness in childhood, from the late sixteenth to the early eighteenth centuries. At this time, the sickness or death of a child was a common occurrence - over a quarter of young people died before the age of fifteen - and yet this subject has received little scholarly attention. Hannah Newton takes three perspectives: first, she investigates medical understandings and treatments of children. She argues that a concept of 'children's physic' existed amongst doctors and laypeople: the young were thought to be physiologically distinct, and in need of special medicines. Secondly, she examines the family's' experience, demonstrating that parents devoted considerable time and effort to the care of their sick offspring, and experienced feelings of devastating grief upon their illnesses and deaths. Thirdly, she takes the strikingly original viewpoint of sick children themselves, offering rare and intimate insights into the emotional, spiritual, physical, and social dimensions of sickness, pain, and death. Newton asserts that children's experiences were characterised by profound ambivalence: whilst young patients were often tormented by feelings of guilt, fears of hell, and physical pain, sickness could also be emotionally and spiritually uplifting, and invited much attention and love from parents. Drawing on a wide array of printed and archival sources, The Sick Child is of vital interest to scholars working in the interconnected fields of the history of medicine, childhood, parenthood, bodies, emotion, pain, death, religion, and gender.

Araucaria forest dynamics in relation to fire frequency in southern Brazil based on fossil and modern pollen dataf

To elucidate the relationship between forest dynamics and fire frequency pollen percentages and charcoal amounts from a 120 cm long peat core and from samples of modern pollen rain were collected along a transect. The study site in southern Brazil is characterized by a species-rich mosaic of grassland-Araucaria forest. It is of crucial importance for management strategies for conservation to understand the development and maintenance of these vegetation mosaics including their sharp forest-grassland boundaries. During the late Holocene, considerable changes occurred in the area. From Anno Domini (AD) 1360 to 1410, the area was dominated by Campos (grassland) vegetation and fire was very common. From AD 1410 to 1500, Araucaria forest expanded and fire was less frequent. From AD 1500 to 1580, Campos grassland spread and the Araucaria forest ceased its development, apparently due to the increase of fire. From AD 1580 to 1935, after a decrease in fire frequency, Araucaria forest expanded again. From AD 1935 to the present, the Araucaria forest expanded while the Campos area decreased. Fire was very rare in this period. The results indicate a strong interaction of forest expansion, forming a mosaic of Campos and Araucaria forest, and the frequency of fire during the past 600 years. A possible collapse of the indigenous population following the post-Colombian colonization in southern Brazil after about AD 1550 may have caused a great reduction of fire frequency. The introduction of cattle (probably after AD 1780) and the resulting decrease of fire frequency might be the reason for forest expansion. Fire is probably the most important factor controlling the dynamics of the forest-grassland mosaics and the formation of sharp borders between these two vegetation types. (C) 2010 Elsevier B.V.

Mellan etnologi och modern sociologi : K. Rob. V. Wikman som medlare i Finland och Sverige

Between ethnology and sociology: K. Rob. V. Wikman as a mediator in Finland and Sweden K. Rob. V. Wikman, professor in sociology at the Åbo Akademi University in Turku, Finland, played a central role both within Finnish and Swedish sociology in the 1940s and 1950s. He was a student of Westermarck and thus his own research represented an ethnosociological tradition, which at that time was challenged by modern, American-influenced sociological ideas. The aim of this article is to discuss the adaptation of “modern sociology” and the drawing of boundaries in Nordic sociology after the Second World War by focusing on Wikman’s work in Finnish as well as Swedish sociology, especially the assessor assignments he was given, and by giving emphasis to some of those that served as border poles or border markers in this process. The comparative starting point gives us reason to discuss some nationally characterized similarities and differences that can be observed in the establishment process of modern sociology in Finland and Sweden.

Carl Maria von Weber’s Overture to Oberon: A History of Recorded Performance

My research examines the recorded performance history of the Overture to Weber’s Oberon in light of these aesthetic goals. I have charted changes in performance practice trends, including in timing, tempo fluctuation, rhythmic accuracy and ensemble, and the use of portamento. The twenty recordings studied that I surveyed span nearly seventy-five years, and include many of the 20th century’s most prominent conductors and orchestras, including groups from Communist Russia, both pre-World War II and post-World War II continental Europe, the British Isles, and the United States.8 Though by no means comprehensive, my selections encompass a diverse sampling of surviving recordings, ensuring a large enough sample size to reflect general trends in the performance of Weber’s masterpiece. My research and analysis confirms the conventional view of a move toward more accurate—but also more cautious, uniform, and inexpressive— performances. Surprisingly, however, this analysis also suggests that we are on the cusp of a new era in orchestra performance practice, one that shares many of the values of the earlier recorded performances. While maintaining today’s high standards of execution, modern performances now look to regain many of the past’s expressive qualities, doing so in sometimes surprising ways.
