    The article tells about the formation of Russian design education in the XXth century. It focuses on the peculiar features and causes of its insufficient effectiveness in the historical context. It studies the dynamics of changes in the priorities related to the artistic and industrial education in Russia and the connection of these processes with socio-political transformations. The article identifies the role of constructivist artists in the formation and approbation of advanced design-engineering techniques. It emphasizes the interdisciplinary essence of the profession of a designer as a special kind of design activities, its organizing, consolidating and progressive origin in the sphere of industrial production and carrying out interdisciplinary studies. It discloses the essence of a new “engineer-artist” profession. It briefly describes the influence of the fundamental principle of design - projectivity, on engineering and design disciplines when the interaction of an artist, an engineer and an architect is achieved on the basis of design, arrangement and inventive art as well as production organization where science and technology form the basis for creative work.

    The paper deals with the analysis of the experimental research conducted by A.M. Rodchenko and Ya.G. Chernikov who became the ancestors of the Soviet design and substantiated the theory of composition, its main terminology as the basis for professional activities of a designer. It is established that a designer working with traditional or post-traditional visual communication relies on the compositional activity which is at the intersection of science and art and therefore has a dual nature. The preference of various compositional techniques and graphic means by the professional community determines the development direction of avant-garde design.

    In Italy, the town of Buggerru, Sardinia, could be considered the cradle of zinc extractive industries. Around Malfidano mine developed a mining village, that reached a population of 8000 inhabitants. It was a peculiar environment since the population included a lot of younger people, women and children workers. The extractive activity exposed all of them to health and life hazards. A hospital was founded in 1868, but was reorganized at the beginning of 20th century. Medical records enable to study the activity of Buggerru hospital, providing information on the complex health events of its inhabitants. For the history of public health and medicine, the events of these hospitals are a subject of interest, being the reflection of major episodes of those times.

    Surgical dermatology has probably existed since the first steps of antique medicine, especially for cutaneous cancer excision and wound reparation. Wonderful descriptions of surgical flaps can be found in the Encyclopedy of Celse, a Roman doctor living in the first century AC. Major progresses in local anesthesy were achieved at the end of the XIXth century, allowing the first dermatologists of the XXth century to perform biopsies and cutaneous surgery with a good control of patient's pain. Electricity was introduced in medicine at the end of the XIXth century, and our ancestors dermatologists used it for electrocoagulation, cauterization and electric hair removal. In the « Pratique dermatologique », the first encyclopedy of dermatology published in 1900, many chapters show how important instrumental and surgical dermatology was. Pigmentary changes induced by surgery and other procedures were probably well known then but were less important than troubles due to scarring, which are mentioned in the early literature. Spontaneous or post-interventional cheloids are well discussed in the early works of Alibert, in the years 1810. This article shows that surgical dermatology is far more ancient than the creation of societies dedicated to it in the XXth century. © 2016 Elsevier Masson SAS. Tous droits réservés.

    Atopic dermatitis has been described under many names before the XXth century, and first illustrated in the early XIXth century. This article presents historical images from the first volumes of Robert Willan to the Pratique dermatologique, the first encyclopedy published in 1900. Many accurate clinical descriptions of the disease can be found in the early treaties of dermatology, including the one published by Thomas Carrere in 1740. Since then, Alibert and Rayer in France, Hebra and Neumann in Vienna and Duhring and Fox in the USA illustrated their atlases with spectacular images of adults or children suffering from AD, or from other diseases that might have been considered as eczema infantile. Color engravings, color lithographs and black and white photographs showed with an increasing precision the semiology of AD, in the context of artistic representations of high quality, that have not been surpassed by modern photographs. At the beginning of the XXth century the clinical presentation, the course and heredity of the disease were perfectly established, introducing a new era of research in physiopathology and treatment in the following decades. © 2017 Elsevier Masson SAS.

    Results of spectroscopic examinations of three paintings that by the formal and stylistic features can be attributed to the Dutch and Flemish schools of the XVII-XVIIIth centuries were presented. It was supposed that one of the paintings was created by David Teniers the Younger. The signature ″L. de Moni″ was found on the paint layer of another painting. Inorganic art pigments including those of the XIXth century were identified using laser-induced breakdown spectroscopy. Fourier-transform IR spectroscopy was used to determine the paint binders, which allowed the lower limits of the creation time of these artworks to be defined. Results of a microscopic examination of the stratigraphic structure revealed that the creation technology of these artworks differed from that of Dutch and Flemish artists of the XVII-XVIIIth centuries. Thus, all three investigated paintings were XXth century stylistic forgeries of Dutch and Flemish paintings of the XVI-XVIIIth centuries.

  9. Early 20th century conceptualization of health promotion.

    PubMed

    Madsen, Wendy

    2017-12-01

    This historical analysis of the term 'health promotion' during the early 20th century in North American journal articles revealed concepts that strongly resonate with those of the 21st century. However, the lineage between these two time periods is not clear, and indeed, this paper supports contentions health promotion has a disrupted history. This paper traces the conceptualizations of health promotion during the 1920s, attempts to operationalize health promotion in the 1930s resulting in a narrowing of the concept to one of health education, and the disappearance of the term from the 1940s. In doing so, it argues a number of factors influenced the changing conceptualization and utilization of health promotion during the first half of the 20th century, many of which continue to present times, including issues around what health promotion is and what it means, ongoing tensions between individual and collective actions, tensions between specific and general causes of health and ill health, and between expert and societal contributions. The paper concludes the lack of clarity around these issues contributed to health promotion disappearing in the mid-20th century and thus resolution of these would be worthwhile for the continuation and development of health promotion as a discipline into the 21st century. © The Author 2016.

    With amplified warming and record sea ice loss, the Arctic is the canary of global warming. The historical Arctic warming is poorly understood, limiting our confidence in model projections. Specifically, Arctic surface air temperature increased rapidly over the early 20th century, at rates comparable to those of recent decades despite much weaker greenhouse gas forcing. Here, we show that the concurrent phase shift of Pacific and Atlantic interdecadal variability modes is the major driver for the rapid early 20th-century Arctic warming. Atmospheric model simulations successfully reproduce the early Arctic warming when the interdecadal variability of sea surface temperature (SST) is properly prescribed. The early 20th-century Arctic warming is associated with positive SST anomalies over the tropical and North Atlantic and a Pacific SST pattern reminiscent of the positive phase of the Pacific decadal oscillation. Atmospheric circulation changes are important for the early 20th-century Arctic warming. The equatorial Pacific warming deepens the Aleutian low, advecting warm air into the North American Arctic. The extratropical North Atlantic and North Pacific SST warming strengthens surface westerly winds over northern Eurasia, intensifying the warming there. Coupled ocean–atmosphere simulations support the constructive intensification of Arctic warming by a concurrent, negative-to-positive phase shift of the Pacific and Atlantic interdecadal modes. Our results aid attributing the historical Arctic warming and thereby constrain the amplified warming projected for this important region. PMID:28559341

    2017-12-01

    We investigate the influence of Pacific and Atlantic multidecadal variability on the Arctic temperature, with a particular focus on the early 20th century Arctic warming. Arctic surface air temperature increased rapidly over the early 20th century, at rates comparable to those of recent decades despite much weaker greenhouse gas forcing than at present. We find that the concurrent phase shift of Pacific and Atlantic multidecadal variability is the major driver for the early 20th century Arctic warming. Atmospheric model simulations reproduce the early Arctic warming when the interdecadal variability of sea surface temperature (SST) is properly prescribed. The early Arctic warming is associated with the cold-to-warm phase shifts of Atlantic and Pacific multidecadal variability modes, a SST pattern reminiscent of the positive phase of the Pacific decadal and Atlantic multidecadal oscillations. The extratropical North Atlantic and North Pacific SST warming strengthens surface westerly winds over northern Eurasia, intensifying the warming there. The equatorial Pacific warming deepens the Aleutian low, advecting warm air to the North American Arctic. Coupled ocean-atmosphere simulations support the constructive intensification of Arctic warming by a concurrent, cold-to-warm phase shift of the Pacific and Atlantic multidecadal variability. Our results aid attributing the historical Arctic warming and thereby constrain the amplified warming projected for this important region.

    The complex early history of infant incubators provides insight into challenges faced by medical professionals as they promoted care for premature infants in the early 20th century. Despite their absence from the narrative to date, nurses played vital roles in the development of neonatal care. Working in many different settings, from incubator-baby shows to the first hospital unit designed specifically for premature infants, nurses administered quality care and promoted advanced treatment for these newborns.

    In a recent paper in this journal, Sule et al. (2011) argued that an early 17th-century Indian mural of the constellation Sagittarius with a dragon-headed tail indicated that the bright supernova of 1604 was also sighted by Indian astronomers. In this paper it will be shown that this identification is based on a misunderstanding of traditional Islamic astrological iconography and that the claim that the mural represents an early 17th-century Indian sighting of the supernova of 1604 has to be rejected.

  9. American Influence on Chinese Physics Study in the Early Twentieth Century

    To save China from the perils she faced in the early twentieth century, the majority of the Chinese seemed to agree that it was necessary to strengthen the country by developing shiye or industry and commerce. For this purpose, they overhauled China's education system and sent a large number of students to study overseas. Many of them enrolled in American colleges, sponsored either by governmental grants or by private funds. As American physics advanced rapidly during the early twentieth century, Chinese physicists studying in top US institutions received first-class professional training. They later went on to become a main driving force in Chinese physics development. The study-in-America programs were apparently more successful than other study-overseas programs. Among other factors, the historical lessons learned from the aborted Chinese Educational Mission in the 1870s, the prevalent and long-time presence of American mission schools in China, and stable public and private funding contributed to their success. American-trained Chinese physicists not only advanced physics study in China but also played leading roles in the development of Chinese science and technology during the twentieth century. This fertile and far-reaching American influence has been embedded in all their accomplishments.

    The presence of nutrition as an independent matter in the educational programs of the Spanish Faculties of Medicine has been scanty until the end of the XXth century. We have witnessed an important development of the specific opportunities for the nutritional sciences in terms of quality and quantity in the XXIst century. Only one Ibero Latin American journal, Archivos Latinoamericanos de Nutrición (ALAN, ISSN 0004-0622), was present in the Journal Citation Reports, Science Edition among the 51 journals under the heading of Nutrition & Dietetics. Three more ibero latin American journals have been incorporated to JCR in the XXIst century, Nutrición Hospitalaria (Nutr Hosp, ISSN 0212-1611) in 2006, Revista de Nutricao (Rev Nutr, ISSN 1415-5273) and Revista Española de Nutrición Comunitaria (Rev Esp Nutr Comunit, ISSN 1135-3074) in 2007. The four journals are having a growing importance in other electronic platforms, rendering an important service to the scientific society, not only in their environment, but also in the rest of the world. Although English language dominates scientific communications, the critical mass of already existing journals in Spanish and the area of influence of this language is a good stimulus for continuing its utilization.

  12. Industrial Characteristics and Employment of Older Manufacturing Workers in the Early-Twentieth-Century United States

    2015-01-01

    This study explores how industry-specific technological, organizational, and managerial features affected the employment of old male manufacturing workers in the early twentieth-century United States. Industrial characteristics favorably related to the employment of old industrial workers include high labor productivity, less capital- and material-intensive production, short workdays, low intensity of work, high job flexibility, and formalized employment relationship. Results show that aged industrial workers were heavily concentrated in “unfavorable” industries, suggesting that the contemporary argument of “industrial scrap heap” was applicable for most of the manufacturing workers in the early twentieth century United States.

  14. The acceleration of the masculine in early-twentieth-century Berlin.

    PubMed

    Prickett, David James

    2012-01-01

    In early-twentieth-century Berlin, agents of speed and industrialisation, such as the railway, contributed to the seemingly unbridled velocity of urban life. Doctors and cultural critics took an ambivalent stance toward the impact of speed and technology on the human body. Critics argued that these factors, in conjunction with sexual excess and prostitution, accelerated the sexual maturation of young men, thereby endangering ‘healthy’ male sexuality. This comparison of Hans Ostwald's socio-literary study Dunkle Winkel in Berlin (1904) with Georg Buschan's sexual education primer Vom Jüngling zum Mann (1911) queries the extent to which speed shaped the understanding of ‘the masculine’ in pre-World-War-I Germany. The essay thus examines Ostwald's and Buschan's arguments and postulates that speed in the city (Berlin) can be seen as a feminised, sexualised force that determined sex in the city. According to this reading, the homosexual urban dandy resisted the accelerated modernist urban tempo, whereas the heterosexual man and hegemonic, heteronormative masculinity yielded to speed. ‘“Das Verhältnis”’ became a fleeting, momentary alternative to stable marital relationships, which in turn contributed to the general ‘crisis’ of – and in– masculinity in early-twentieth-century Berlin.

    2017-11-01

    In recent years much research has been devoted to global and regional climate changes. Special attention was paid to climate extremes, such as droughts and excessive moisture events. In this study the moisture and aridity of Southern Siberia are estimated using web-GIS called “CLIMATE”. The system “CLIMATE” is part of a hardware and software cloud storage complex for data analysis of various climatic data sets, with algorithms for searching, extracting, processing, and visualizing the data. The ECMWF ERA-Interim reanalysis data for Southern Siberia (50-65°N, 60-120°E) from 1979 to 2010 with a grid cell of 0.75×0.75° is used. Some hydrothermal conditions are estimated using the so-called Ped index (Si), which is a normalized indicator of the ratio of air temperature to precipitation. The mountain regions of Eastern Siberia are becoming more and more arid each month during the last 30 years. In Western Siberia, aridity increases in May and decreases in June, in the other months positive and negative trends are found. The greatest differences between the trends of the aridity index (Si), air temperature, and precipitation are observed in July.

  16. The Not-so-Dark Ages: ecology for human growth in medieval and early twentieth century Portugal as inferred from skeletal growth profiles.

    PubMed

    Cardoso, Hugo F V; Garcia, Susana

    2009-02-01

    This study attempts to address the issue of relative living standards in Portuguese medieval and early 20th century periods. Since the growth of children provides a good measure of environmental quality for the overall population, the skeletal growth profiles of medieval Leiria and early 20th century Lisbon were compared. Results show that growth in femur length of medieval children did not differ significantly from that of early 20th century children, but after puberty medieval adolescents seem to have recovered, as they have significantly longer femora as adults. This is suggestive of greater potential for catch-up growth in medieval adolescents. We suggest that this results from distinct child labor practices, which impact differentially on the growth of Leiria and Lisbon adolescents. Work for medieval children and adolescents were related to family activities, and care and attention were provided by family members. Conversely, in early 20th century Lisbon children were more often sent to factories at around 12 years of age as an extra source of family income, where they were exploited for their labor. Since medieval and early 20th century children were stunted at an early age, greater potential for catch-up growth in medieval adolescents results from exhausting work being added to modern adolescent's burdens of disease and poor diet, when they entered the labor market. Although early 20th century Lisbon did not differ in overall unfavorable living conditions from medieval Leiria, after puberty different child labor practices may have placed modern adolescents at greater risk of undernutrition and poor growth. 2008 Wiley-Liss, Inc.

    1990-01-01

    In the 21st century, the early missions to Mars will entail unmanned Rover and Sample Return reconnaissance missions to be followed by manned exploration missions. High performance leverage technologies will be required to reach Mars and return to earth. This paper describes the mission concepts currently identified for these early Mars missions. These concepts include requirements and capabilities for Mars and earth aerocapture, Mars surface operations and ascent, and Mars and earth rendezvous. Although the focus is on the unmanned missions, synergism with the manned missions is also discussed.

    Recently the Southwest has experienced a spate of dryness, which presents a challenge to the sustainability of current water use by human and natural systems in the region. In the Colorado River Basin, the early 21st century drought has been the most extreme in over a century of Colorado River flows, and might occur in any given century with probability of only 60%. However, hydrological model runs from downscaled Intergovernmental Panel on Climate Change Fourth Assessment climate change simulations suggest that the region is likely to become drier and experience more severe droughts than this. In the latter half of the 21st century the models produced considerably greater drought activity, particularly in the Colorado River Basin, as judged from soil moisture anomalies and other hydrological measures. As in the historical record, most of the simulated extreme droughts build up and persist over many years. Durations of depleted soil moisture over the historical record ranged from 4 to 10 years, but in the 21st century simulations, some of the dry events persisted for 12 years or more. Summers during the observed early 21st century drought were remarkably warm, a feature also evident in many simulated droughts of the 21st century. These severe future droughts are aggravated by enhanced, globally warmed temperatures that reduce spring snowpack and late spring and summer soil moisture. As the climate continues to warm and soil moisture deficits accumulate beyond historical levels, the model simulations suggest that sustaining water supplies in parts of the Southwest will be a challenge.

    Recently the Southwest has experienced a spate of dryness, which presents a challenge to the sustainability of current water use by human and natural systems in the region. In the Colorado River Basin, the early 21st century drought has been the most extreme in over a century of Colorado River flows, and might occur in any given century with probability of only 60%. However, hydrological model runs from downscaled Intergovernmental Panel on Climate Change Fourth Assessment climate change simulations suggest that the region is likely to become drier and experience more severe droughts than this. In the latter half of the 21st century the models produced considerably greater drought activity, particularly in the Colorado River Basin, as judged from soil moisture anomalies and other hydrological measures. As in the historical record, most of the simulated extreme droughts build up and persist over many years. Durations of depleted soil moisture over the historical record ranged from 4 to 10 years, but in the 21st century simulations, some of the dry events persisted for 12 years or more. Summers during the observed early 21st century drought were remarkably warm, a feature also evident in many simulated droughts of the 21st century. These severe future droughts are aggravated by enhanced, globally warmed temperatures that reduce spring snowpack and late spring and summer soil moisture. As the climate continues to warm and soil moisture deficits accumulate beyond historical levels, the model simulations suggest that sustaining water supplies in parts of the Southwest will be a challenge.

    2016-02-01

    By combining digital humanities text-mining tools and a qualitative approach, we examine changing concepts in forestry journals in Sweden and the United States (US) in the early twentieth and early twenty-first centuries. Our first hypothesis is that foresters at the beginning of the twentieth century were more concerned with production and less concerned with ecology than foresters at the beginning of the twenty-first century. Our second hypothesis is that US foresters in the early twentieth century were less concerned with local site conditions than Swedish foresters. We find that early foresters in both countries had broader-and often ecologically focused-concerns than hypothesized. Ecological concerns in the forestry literature have increased, but in the Nordic countries, production concerns have increased as well. In both regions and both time periods, timber management is closely connected to concerns about governance and state power, but the forms that governance takes have changed.

  11. Surviving the Lunacy Act of 1890: English Psychiatrists and Professional Development during the Early Twentieth Century.

    PubMed

    Takabayashi, Akinobu

    2017-04-01

    In recent decades, historians of English psychiatry have shifted their major concerns away from asylums and psychiatrists in the nineteenth century. This is also seen in the studies of twentieth-century psychiatry where historians have debated the rise of psychology, eugenics and community care. This shift in interest, however, does not indicate that English psychiatrists became passive and unimportant actors in the last century. In fact, they promoted Lunacy Law reform for a less asylum-dependent mode of psychiatry, with a strong emphasis on professional development. This paper illustrates the historical dynamics around the professional development of English psychiatry by employing Andrew Abbott's concept of professional development. Abbott redefines professional development as arising from both abstraction of professional knowledge and competition regarding professional jurisdiction. A profession, he suggests, develops through continuous re-formation of its occupational structure, mode of practice and political language in competing with other professional and non-professional forces. In early twentieth-century England, psychiatrists promoted professional development by framing political discourse, conducting a daily trade and promoting new legislation to defend their professional jurisdiction. This professional development story began with the Lunacy Act of 1890, which caused a professional crisis in psychiatry and led to inter-professional competition with non-psychiatric medical service providers. To this end, psychiatrists devised a new political rhetoric, 'early treatment of mental disorder', in their professional interests and succeeded in enacting the Mental Treatment Act of 1930, which re-instated psychiatrists as masters of English psychiatry.

  13. Reconstructing early 17th century estuarine drought conditions from Jamestown oysters.

    PubMed

    Harding, Juliana M; Spero, Howard J; Mann, Roger; Herbert, Gregory S; Sliko, Jennifer L

    2010-06-08

    Oysters (Crassostrea virginica) were a central component of the Chesapeake Bay ecosystem in 1607 when European settlers established Jamestown, VA, the first permanent English settlement in North America. These estuarine bivalves were an important food resource during the early years of the James Fort (Jamestown) settlement while the colonists were struggling to survive in the face of inadequate supplies and a severe regional drought. Although oyster shells were discarded as trash after the oysters were eaten, the environmental and ecological data recorded in the bivalve geochemistry during shell deposition remain intact over centuries, thereby providing a unique window into conditions during the earliest Jamestown years. We compare oxygen isotope data from these 17th century oyster shells with modern shells to quantify and contrast estuarine salinity, season of oyster collection, and shell provenance during Jamestown colonization (1609-1616) and the 21st century. Data show that oysters were collected during an extended drought between fall 1611 and summer 1612. The drought shifted the 14 psu isohaline above Jamestown Island, facilitating individual oyster growth and extension of oyster habitat upriver toward the colony, thereby enhancing local oyster food resources. Data from distinct well layers suggest that the colonists also obtained oysters from reefs near Chesapeake Bay to augment oyster resources near Jamestown Island. The oyster shell season of harvest reconstructions suggest that these data come from either a 1611 well with a very short useful period or an undocumented older well abandoned by late 1611.

    2017-07-03

    This article reveals previously overlooked connections between eighteenth-century antiquarianism and early twentieth-century sexual science by presenting a comparative reading of two illustrated books: An Account of the Remains of the Worship of Priapus , by British antiquarian scholar Richard Payne Knight (1750-1824), and Die Weltreise eines Sexualforschers (The World Journey of a Sexologist), by German sexual scientist Magnus Hirschfeld (1868-1935). A close analysis of these publications demonstrates the special status of material artefacts and the strategic engagement with visual evidence in antiquarian and scientific writings about sex. Through its exploration of the similarities between antiquarian and sexual scientific thought, the article demonstrates the centrality of material culture to the production of sexual knowledge in the Western world. It also opens up new perspectives on Western intellectual history and on the intellectual origins of sexual science. While previous scholarship has traced the beginnings of sexual science back to nineteenth-century medical disciplines, this article shows that sexual scientists drew upon different forms of evidence and varied methodologies to produce sexual knowledge and secure scientific authority. As such, sexual science needs to be understood as a field with diverse intellectual roots that can be traced back (at least) to the eighteenth century.

  17. Potentially induced earthquakes during the early twentieth century in the Los Angeles Basin

    2016-01-01

    Recent studies have presented evidence that early to mid‐twentieth‐century earthquakes in Oklahoma and Texas were likely induced by fossil fuel production and/or injection of wastewater (Hough and Page, 2015; Frohlich et al., 2016). Considering seismicity from 1935 onward, Hauksson et al. (2015) concluded that there is no evidence for significant induced activity in the greater Los Angeles region between 1935 and the present. To explore a possible association between earthquakes prior to 1935 and oil and gas production, we first revisit the historical catalog and then review contemporary oil industry activities. Although early industry activities did not induce large numbers of earthquakes, we present evidence for an association between the initial oil boom in the greater Los Angeles area and earthquakes between 1915 and 1932, including the damaging 22 June 1920 Inglewood and 8 July 1929 Whittier earthquakes. We further consider whether the 1933 Mw 6.4 Long Beach earthquake might have been induced, and show some evidence that points to a causative relationship between the earthquake and activities in the Huntington Beach oil field. The hypothesis that the Long Beach earthquake was either induced or triggered by an foreshock cannot be ruled out. Our results suggest that significant earthquakes in southern California during the early twentieth century might have been associated with industry practices that are no longer employed (i.e., production without water reinjection), and do not necessarily imply a high likelihood of induced earthquakes at the present time.

  18. Late nineteenth to early twenty-first century behavior of Alaskan glaciers as indicators of changing regional climate

    2007-01-01

    Alaska's climate is changing and one of the most significant indications of this change has been the late 19th to early 21st century behavior of Alaskan glaciers. Weather station temperature data document that air temperatures throughout Alaska have been increasing for many decades. Since the mid-20th century, the average change is an increase of ?????2.0????C. In order to determine the magnitude and pattern of response of glaciers to this regional climate change, a comprehensive analysis was made of the recent behavior of hundreds of glaciers located in the eleven Alaskan mountain ranges and three island areas that currently support glaciers. Data analyzed included maps, historical observations, thousands of ground-and-aerial photographs and satellite images, and vegetation proxy data. Results were synthesized to determine changes in length and area of individual glaciers. Alaskan ground photography dates from 1883, aerial photography dates from 1926, and satellite photography and imagery dates from the early 1960s. Unfortunately, very few Alaskan glaciers have any mass balance observations. In most areas analyzed, every glacier that descends below an elevation of ?????1500??m is currently thinning and/or retreating. Many glaciers have an uninterrupted history of continuous post-Little-Ice-Age retreat that spans more than 250??years. Others are characterized by multiple late 19th to early 21st century fluctuations. Today, retreating and/or thinning glaciers represent more than 98% of the glaciers examined. However, in the Coast Mountains, St. Elias Mountains, Chugach Mountains, and the Aleutian Range more than a dozen glaciers are currently advancing and thickening. Many currently advancing glaciers are or were formerly tidewater glaciers. Some of these glaciers have been expanding for more than two centuries. This presentation documents the post-Little-Ice-Age behavior and variability of the response of many Alaskan glaciers to changing regional climate. ?? 2006.

    Ratcliff, Jessica

    2016-09-01

    At the turn of the nineteenth century, at its headquarters in the City of London, the Honourable East India Company established a new museum and library. By midcentury this museum would contain one of Europe’s most extensive collections of the natural history, arts, and sciences of Asia. This essay uses the early history of the company’s museum, focusing in particular on its natural history collections, to explore the material relationship between scientific practice and the imperial political economy. Much of the collections had been gathered in the wake of military campaigns, trade missions, or administrative surveys. Once specimens and reports arrived in Leadenhall Street and passed through the museum storage areas, this plunder would become the stuff of science, going on to feed the growth of disciplines, societies, and projects in Britain and beyond. In this way, the East India Company was integral to the information and communication infrastructures within which many sciences then operated. Collections-based disciplines and societies flourished in this period; their growth, it is argued, was coextensive with administrative and political economic change at institutions like the East India Company. The essay first explores the company’s practices and patterns of collecting and then considers the consequences of this accumulation for aspects of scientific practice—particularly the growth of scientific societies—in both London and Calcutta.

    Lichens have long been known to be good indicators of air quality and atmospheric deposition. Xanthoria parietina was selected to investigate past (sourced from a herbarium) and present-day trace metal pollution in four sites from South-West France (close to Albi). Enrichment factors, relationships between elements and hierarchical classification indicated that the atmosphere was mainly impacted by coal combustion (as shown by As, Pb or Cd contamination) during the early twentieth century, whereas more recently, another mixture of pollutants (e.g. Sb, Sn, Pb and Cu) from local factories and car traffic has emerged. The Rare Earth Elements (REE) and other lithogenic elements indicated a higher dust content in the atmosphere in the early twentieth century and a specific lithological local signature. In addition to long-range atmospheric transport, local urban emissions had a strong impact on trace element contamination registered in lichens, particularly for contemporary data.

  3. Remembering and forgetting Freud in early twentieth-century dreams.

    PubMed

    Forrester, John

    2006-03-01

    The paper explores the use of Freud's methods of dream interpretation by four English writers of the early twentieth century: T. H. Pear, W. H. R. Rivers, Ernest Jones, and Alix Strachey. Each employed their own dreams in rather different ways: as part of an assessment of Freud's work as a psychological theory, as illustrative of the cogency of Freud's method and theories as part of the psychoanalytic process. Each adopted different approaches to the question of privacy and decorum. The paper argues that assessment of the impact of Freud's work must take account of the application of the method to the researcher's own dreams and the personal impact this process of analysis had upon them, and must also gauge how the dreamers' deployment of Freud's methods influenced their explicit relationship to him and his theories.

    2016-01-01

    Pope Leo XII marked the 1825 Jubilee by visiting the hospitals of Rome. Italy was recovering from the French invasion that had disrupted social and religious structures. The Visitors investigated conditions, and recommended changes. By 1826, eight large hospitals were ordered to unite, but, three years later, the order was rescinded. Based on the Visit's mostly unexamined records in the Vatican Secret Archives, hospital registers, and minutes of the governing council held in the Archivio di Stato di Roma, this paper reconstructs the network of Rome's hospitals in the early 19 th century. It also compares Roman hospitals to its Parisian counterparts, especially with respect to governance and education. Finally, it examines the merger as an early example of a practice that remains vibrant (if controversial) today.

    Prior to the advent of the Wasserman Test as a diagnostic tool for Syphilis, the identification rate for Syphilis at the Mysore Government Mental Hospital in Southern India was 1%. With the introduction of the test, there was a dramatic increase in the diagnosis of Syphilis, with 17% of the patients testing positive. This paper throws light on the early notions of Syphilis and GPI, societal responses to the disease, early misdiagnosis, the advent of the Wasserman test and treatment management as reflected in the records of the early 20th century at the Mysore Government Mental Hospital (currently known as NIMHANS).

    A new, Romantic type of mathematical story appeared in the early nineteenth century that was radically different from the sober narrative characteristic of the previous generation of mathematicians. At the same time, a new mathematical practice emerged that differed sharply from the understanding and practice of mathematics during the Enlightenment. These parallel developments are inseparable: the new type of mathematical practice went hand in hand with the new mathematical story.

    2016-08-01

    This paper sheds new light on the prevalence of evolutionary ideas in Scotland in the early nineteenth century and establish what connections existed between the espousal of evolutionary theories and adherence to the directional history of the earth proposed by Abraham Gottlob Werner and his Scottish disciples. A possible connection between Wernerian geology and theories of the transmutation of species in Edinburgh in the period when Charles Darwin was a medical student in the city was suggested in an important 1991 paper by James Secord. This study aims to deepen our knowledge of this important episode in the history of evolutionary ideas and explore the relationship between these geological and evolutionary discourses. To do this it focuses on the circle of natural historians around Robert Jameson, Wernerian geologist and professor of natural history at the University of Edinburgh from 1804 to 1854. From the evidence gathered here there emerges a clear confirmation that the Wernerian model of geohistory facilitated the acceptance of evolutionary explanations of the history of life in early nineteenth-century Scotland. As Edinburgh was at this time the most important center of medical education in the English-speaking world, this almost certainly influenced the reception and development of evolutionary ideas in the decades that followed.

    The new field of paleomicrobiology allows past outbreaks to be identified by testing dental pulp of human remains with PCR. We identified a mass grave in Douai, France dating from the early XVIII(th) century. This city was besieged during the European war of Spanish succession. We tested dental pulp from 1192 teeth (including 40 from Douai) by quantitative PCR (qPCR) for R. prowazekii and B. quintana. We also used ultra-sensitive suicide PCR to detect R. prowazekii and genotyped positive samples. In the Douai remains, we identified one case of B. quintana infection (by qPCR) and R. prowazekii (by suicide PCR) in 6/21 individuals (29%). The R. prowazekii was genotype B, a genotype previously found in a Spanish isolate obtained in the first part of the XX(th) century. Louse-borne outbreaks were raging during the XVIII(th) century; our results support the hypothesis that typhus was imported into Europe by Spanish soldiers from America.

    2015-12-01

    Taking a micro-historical approach, this paper explores the business activities of Elizabeth Carter and Elizabeth Hatchett, two married women who operated together as pawnbrokers in London in the early decades of the eighteenth century. Based on a protracted inheritance dispute through which their extensive dealings come to light, the discussion assesses married women's lending and investment strategies in a burgeoning metropolitan economy; the networks through which women lenders operated; and the extent to which wives could sidestep the legal conventions of 'coverture' which restricted their ownership of moveable property. It is argued that the moneylending and asset management activities of women like Carter and Hatchett were an important part of married women's work that did not simply consolidate neighbourhood ties but that placed them at the heart of the early modern economy.

    The major government commissions on immigration and crime in the early twentieth century relied on evidence that suffered from aggregation bias and the absence of accurate population data, which led them to present partial and sometimes misleading views of the immigrant-native criminality comparison. With improved data and methods, we find that in 1904, prison commitment rates for more serious crimes were quite similar by nativity for all ages except ages 18 and 19, for which the commitment rate for immigrants was higher than for the native-born. By 1930, immigrants were less likely than natives to be committed to prisons at all ages 20 and older, but this advantage disappears when one looks at commitments for violent offenses. The time series pattern reflects a growing gap between natives and immigrants at older ages, one that was driven by sharp increases in the commitment rates of the native-born, while commitment rates for the foreign-born were remarkably stable.

  18. Floods of the Maros river in the early modern and modern period (16th-20th centuries)

    Kiss, Andrea

    2016-04-01

    In the poster presentation a series of historical and recent floods of the Maros river, with special emphasis on the flood events occurred on the lower sections, are presented. Similar to the Hungarian flood databases of the Middle-Danube and Lower-Tisza, the main sources of investigations are the institutional (legal-administrative) documentary evidence (e.g. Szeged and Makó town council protocols and related administrative documentation, Csanád County meeting protocols) mainly from the late 17th-early 18th century onwards. However, in case of the Maros river there is an increased importance of narrative sources, with special emphasis on the early modern period (16th-17th century): in this case the (mainly Transylvanian) narratives (chronicles, diaries, memoires etc.) written by aristocrats, other noblemen and town citizens have particular importance. In the presentation the frequency of detected flood events, from the mid-16th century onwards (with an outlook on sporadic medieval evidence), is provided; moreover, a 3-scaled magnitude classification and a seasonality analysis are also presented. Floods of the Maros river, especially those of the lower river sections, often cannot be understood and discussed without the floods of the (Lower-)Tisza; thus, a comparison of the two flood series are also a subject of discussion. Unlike the Lower-Tisza, the Maros is prone to winter and early spring ice jam floods: since the floods that belonged to this type (similar to those of the Middle-Danube at Budapest) were the most destructive among the flood events of the river, this flood type, and the greatest flood events (e.g. 1751-1752, 1784) are also presented in more detail.

    One of the major Dutch landscapes is formed by lowland rivers. They divide the country in a southern and a northern part, both physically and culturally. We screened the freely available database of 19th and early 20th century paintings of Simonis & Buunk, www.simonis-buunk.com, looking for lowland river landscapes depicting geodiversity and cultural heritage relationships (See References for other landscapes). Emperor Napoleon declared The Netherlands as naturally belonging to his empire as its lands originated from muds originating in France and transported there by the big rivers. A description that may have given rise to the idea of the Netherlands as a delta, but from a geomorphological perspective The Netherlands consists of series of river plains of terrestrial origin, of which the north-western part are subsiding and invaded by the sea. Now, the rivers Meuse and Rhine (including its branches Waal and IJssel) meander through ever larger river plains before reaching the North Sea. They end in estuaries, something one would not expect of rivers with catchments discharging a large part of Western Europe. Apart from the geological subsidence, the estuaries might be due to human interference, the exploitation of peat and building of dikes since the 11th century, heavy storms and the strong tidal currents. Archaeological finds show Vikings and Romans already used the river Rhine system for trading and transporting goods. During the Roman Empire the Rhine was part of The Limes, the northern defence line of the empire. Romans already influenced the distribution of water over the different river branches. Since the middle of the 19th century groins and canalization drastically changed the character of the rivers. The 19th and early 20th century landscape paintings illustrate this change as well as changes in land use. Examples of geodiversity and cultural heritage relationships shown: - meanders and irregular banks disappear as river management increases, i.a. bends

    2013-01-01

    This article explores the articulation of the crime scene as a distinct space of theory and practice in the early twentieth century. In particular it focuses on the evidentiary hopes invested in what would at first seem an unpromising forensic object: dust. Ubiquitous and, to the uninitiated, characterless, dust nevertheless featured as an exemplary object of cutting-edge forensic analysis in two contemporary domains: writings of criminologists and works of detective fiction. The article considers how in these texts dust came to mark the furthest reach of a new forensic capacity they were promoting, one that drew freely upon the imagination to invest crime scene traces with meaning.

  3. Early 20th century untrained nursing staff in the Rockhampton district: a necessary evil?

    Madsen, Wendy

    2005-08-01

    This paper explores the role of untrained nursing staff within the nursing services of the Rockhampton region, Queensland, Australia, throughout the early 20th century. It details who these nurses were, where they worked and how their work was affected by factors such as legislation and social changes. Despite the increasing prevalence of trained nurses from the late 19th century, nurses who had never undergone any formal training continued to gain work in hospitals, institutions and their local communities. This paper is an historical analysis of a wide range of primary source material relating to untrained nursing staff. The primary source material used related specifically to a limited geographical region in Australia. Untrained nursing staff primarily worked as private duty nurses at the beginning of the 20th century. However, as the century progressed, their opportunities to work as untrained nursing staff tended towards institutions dealing with the chronically ill and the aged. As a result of this transition, their profile altered from that of a married/widowed woman living at home with dependents to one who could live on-site at the institution with no dependents. Furthermore, the level of autonomy of the untrained nurse decreased dramatically throughout this period from being relatively independent to being under the control of a trained nurse within the institution. Consideration of the historical evolution of untrained nursing staff challenges some of the assumptions made about this category of nurse, assumptions that can affect current relationships between professional nurses and others who undertake nursing work.

    Children in the United States have benefited considerably from advancements in medical and nursing science over the course of the past 200 years. The twentieth century saw dramatic declines in the incidence of childhood diseases; the prevalence of measles, haemophilus influenzae type B, diphtheria, rubella and tetanus are at all time lows (CDC, 2006). Indeed, many pediatric nurses have never seen any of these diseases, something that would certainly have startled their predecessors just a few generations ago. Before the mid- twentieth century, caring for children with communicable diseases represented the cornerstone of pediatric nursing practice. Now that the incidence has decreased among American children, it is easy to forget about these diseases that once decimated whole communities. This article tries to peel back the mists of history by studying children's health in one rural New England town during the days of the early republic in the 1830s.

  6. Observability, Anschaulichkeit and Abstraction: A Journey into Werner Heisenberg's Science and Philosophy

    NASA Astrophysics Data System (ADS)

    Lacki, Jan

    2003-09-01

    Werner Heisenberg was one of the greatest physicists of the 20th century. He participated as a front rank actor in the shaping of a good part of XXth century physics and directly witnessed most of the intellectual struggles which led to what he called “Wandlungen in den Grundlagen der exakten Naturwissenschaft”. This expression is borrowed from one of the many talks and writings he devoted to the analysis of the scientific and philosophical implications of his, and his fellows physicists, findings. Indeed, Heisenberg's scientific activity increasingly reflected his more general intellectual views. This makes him another magnificent representative of a glorious linage going from the remote times of modern science to Einstein, Bohr and the like. This “philosophical” vein started early in his scientific life, and got stronger with time, prompted by the highly demanding scientific, but also social and political context of his mature years.

  7. Birth Attendants and Midwifery Practice in Early Twentieth-century Derbyshire

    PubMed Central

    Reid, Alice

    2012-01-01

    Summary The 1902 Midwives Act introduced training and supervision for midwives in England and Wales, outlawing uncertified-and-untrained midwives (handywomen) and phasing out certified-but-untrained (bona fide) midwives. This paper compares the numbers and practices of these two different types of birth attendant with each other, with qualified and certified midwives and with doctors in early twentieth-century Derbyshire during this period of change, and examines the spatial and social factors influencing women's choice of birth attendant. It finds that the new legislation did not entirely eliminate continuity in traditional practices and allegiance, and that both social and spatial factors governed the choice of delivery attendant, with fewer midwives available in rural areas and a surviving network of untrained bona fide midwives in mining communities. Within this spatial pattern, however, although wealthier women were more likely to have chosen a doctor or a qualified midwife, familiarity and loyalty allowed bona fide midwives to maintain their case loads.

  10. Priestley's Shadow and Lavoisier's Influence: Electricity and Heat in the Late Eighteenth and Early Nineteenth Centuries

    NASA Astrophysics Data System (ADS)

    Fisher, Amy

    In the late eighteenth century, Joseph Priestley argued that any complete theory of heat also had to explain electrical phenomena, which manifested many similar effects to heat. For example, sparking or heating a sample of trapped air caused a reduction in the volume of air and made the gas toxic to living organisms. Because of the complexity of electrical and thermal phenomena, Antoine Lavoisier did not address electrical action in his published works. Rather, he focused on those effects produced by heating alone. With the success of Lavoisier's caloric theory of heat, natural philosophers and chemists continued to debate the relationship between heat and electricity. In this presentation, I compare and contrast the fate of caloric in early-nineteenth-century electrical studies via the work of two scientists: Humphry Davy in Britain and Robert Hare in America.

  12. Robert Hare's Theory of Galvanism: A Study of Heat and Electricity in Early Nineteenth-Century American Chemistry.

    PubMed

    2018-04-09

    As a professor of chemistry at the University of Pennsylvania, Robert Hare actively shaped early American science. He participated in a large network of scholars, including Joseph Henry, François Arago, and Jacob Berzelius, and experimented with and wrote extensively about electricity and its associated chemical and thermal phenomena. In the early nineteenth century, prominent chemists such as Berzelius and Humphry Davy proclaimed that a revolution had occurred in chemistry through electrical research. Examining Robert Hare's contributions to this discourse, this paper analyzes how Hare's study of electricity and the caloric theory of heat led him to propose a new theory of galvanism. It also examines the reception of Hare's work in America and Great Britain, highlighting the contributions of early American chemists to the development of electrochemistry.

    We present the results of the surveys on sunspots and auroral candidates in Rikkokushi, Japanese official histories from the early 7th century to 887, to review the solar and auroral activities. In total, we found one sunspot record and 13 auroral candidates in Rikkokushi. We then examine the records of the sunspots and auroral candidates, compare the auroral candidates with the lunar phase to estimate their reliability, and compare the records of the sunspots and auroral candidates with the contemporary total solar irradiance reconstructed from radioisotope data. We also identify the locations of the observational sites to review possible equatorward expansion of the auroral oval. These discussions suggest a major gap in auroral candidates from the late 7th to early 9th centuries, which includes the candidate of the grand minimum reconstructed from the radioisotope data, a similar tendency as the distributions of sunspot records in contemporary China, and a relatively high magnetic latitude of observational sites with a higher potential for observing aurorae more frequently than at present.

    Modernity has been antithetical to heritage conservation in the twentieth century. The value of inherited buildings was not widely acknowledged by government officials, politicians, architects, planners and the broader community until the' 1970s. From the turn of the century, a coalition of pioneering preservationists in Sydney confronted a formidable growth mentality, which linked preservation with economic and cultural stasis.

    PubMed

    2002-03-01

    In early nineteenth-century Britain the use of pictures in introducing novices to the study of science was contentious, leading to debates over the ways in which words and images constituted knowledge and over the role of pleasure in intellectual pursuits. While recent studies have stressed visual representation as a critical element of science and considered its relation to the written word in conveying information, this essay explores the nineteenth-century preoccupation with the mind and mental faculties in relation to corporeal responses to explain concerns over the role of images and the process of recognition. By considering illustration in this way, it argues that popular botany was defined by many expert naturalists as the means by which private individuals could best be encouraged to extend their aesthetic appreciation and love of plants to an active and participatory pursuit of science.

  19. Evidence of active dune sand on the Great Plains in the 19th century from accounts of early explorers

    1995-01-01

    Dune fields are found in several areas of the Great Plains, and though mostly stabilised today, the accounts of early explorers show that they were more mobile in the last century. Using an index of dune mobility and tree ring data, it is found that these periods of mobility were related to temperature-induced drought, the high temperatures increasing evapotranspiration. Explorers also record that rivers upwind of these dune fields had shallow braided channels in the 19th century, and these would have supplied further aeolian sand. It is concluded that these dunes are extremely susceptible to climate change and that it may not need global warming to increase their mobility again. -K.Clayton

    Climate change is a key emerging threat to the global environment. It imposes long lasting impacts both at regional and national level. In the recent era, global warming and extreme temperatures have drawn great interest to the scientific community. As in a past century considerable increase in global surface temperatures have been observed and predictions revealed that it will continue in the future. In this regard, current study mainly focused on analysis of regional climatic change (annual minimum temperature trends and its correlation with land surface temperatures in the early 21st century in Punjab) for a period of 1979-2013. The projected model data European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-Interim) has been used for eight Tehsils of Punjab i.e., annual minimum temperatures and annual seasonal temperatures. Trend analysis of annual minimum and annual seasonal temperature in (Khushab, Noorpur, Sargodha, Bhalwal, Sahiwal, Shahpur, Sillanwali and Chinoit) tehsils of Punjab was carried out by Regression analysis and Mann-Kendall test. Landsat 5 Thematic Mapper (TM) data was used in comparison with Model data for the month of May from the years 2000, 2009 and 2010. Results showed that no significant trends were observed in annual minimum temperature. A significant change was observed in Noorpur, Bhalwal, Shahpur, Sillanwali, Sahiwal, Chinoit and Sargodha tehsils during spring season, which indicated that this particular season was a transient period of time.

  9. Rapid changes in the seasonal sea level cycle along the US Gulf coast in the early 21st century

    The seasonal cycle is an energetic component in the sea level spectrum and dominates the intra-annual sea level variability outside the semidiurnal and diurnal tidal bands in most regions. Changes in the annual or semi-annual amplitudes or phase lags have an immediate impact on marine coastal systems. Increases in the amplitudes or phase shifts towards the storm surge season may for instance exacerbate the risk of coastal flooding and/or beach erosion, and the ecological health of estuarine systems is also coupled to the seasonal sea level cycle. Here, we investigate the temporal variability of the seasonal harmonics along the US Gulf of Mexico (GOM) coastline using records from 13 tide gauges providing at least 30 years of data in total and at least 15 years for the period after 1990. The longest records go back to the early 20th century. Running Fourier analysis (with a window length of 5-years) is used to extract the seasonal harmonics from the observations. The resulting time series show a considerable decadal variability and no longer-term changes are found in the phase lags and the semi-annual amplitude. The amplitude of the dominating annual cycle in contrast shows a tendency towards higher values since the turn of the century at tide gauges in the eastern part of the GOM. This increase of up to more than 25% is found to be significant at the 90% confidence level for most tide gauges along the coastline of West Florida and at the 75% confidence level for virtually all stations in the eastern GOM (from Key West to Dauphin Island). Monthly mean sea level sub-series show that the changes are partly due to smaller values in the cold season but mostly a result of higher values in the warm season, i.e. sea levels tend to be higher during the hurricane season. We use information on the steric sea level component, sea surface and air temperature, wind forcing, precipitation, and sea level pressure to explain the mechanisms driving the decadal variability in the

  10. Metal Construction Toys of the Early Twentieth Century: Their Astronomical Applications

    2004-12-01

    During the early twentieth century several toy manufacturers around the globe introduced construction toys in the form of sets of metal parts which could be assembled into a variety of models. The two most successful were the Erector Set, introduced in the United States by A.C. Gilbert in 1913, and the Meccano Set, patented in 1901 in England by Frank Hornby. Whereas the Erector Set never developed beyond being a child's toy, Hornby envisioned his Meccano system as providing a way to teach principles of mechanical engineering to young schoolboys. Indeed, his sets were first marketed under the name "Mechanics Made Easy", and were endorsed by Dr. H.S. Hele-Shaw, Head of the Engineering Department at Liverpool University. Popularity of the new Meccano sets spread throughout the world, spawning the formation of numerous amateur societies composed of adolescent boys and an increasing number of adult hobbyists. The variety of parts increased during the first third of the century, and increasingly sophisticated models were constructed and exhibited in competitive events. Among these were several clocks of remarkable accuracy, and at least one equatorial mounting for a small astronomical telescope. At the same time, many university science and engineering departments found these interchangeable metal parts invaluable in the construction of experimental apparatus. In 1934 a small-scale replica of Vannevar Bush's Differential Analyzer was constructed at the University of Manchester, and used for many years to perform mathematical computations. The introduction in 1928 of a flanged ring with 73 (a sub-multiple of 365) teeth allowed for construction of accurate orreries and astronomical clocks. The most remarkable of these was the Astronomical Clock constructed in the period 1924-1932 by M. Alexandre Rahm of Paris.

  11. Plastic body, permanent body: Czech representations of corporeality in the early twentieth century.

    2009-12-01

    In the early twentieth century, the body was seen as both an ontogenetic and a phylogenetic entity. In the former case, its individual development, it was manifestly changeable, developing from embryo to maturity and thence to a state of decay. But in the latter case, concerning its development as a species, the question was an open one. Was its phylogenetic nature a stationary snapshot of the slow process of evolution, or was this too mutable? Historians have emphasised that the question of acquired inheritance remained open into the twentieth century; this paper explores how various constructions of the individual as a phylogenetic episode--a stage in the race's evolution--related to representations of the body in the same period. A discussion of the work of the brothers Josef and Karel Capek offers a contextualised answer to the question of bodily representation. Karel Capek (1890-1938) explored the nature of the 'average man' through two different organisms, the robot and the amphibian, epitomes respectively of corporeal permanence and plasticity. Josef Capek (1887-1945), along with other members of the Group of Plastic Artists, explored visual representations of the body that challenged cubist Bergsonian norms. In so doing, he affirmed what his brother also held: that despite the constrictions imposed by the oppressive political conditions in which the Czechs found themselves, the individual body was a fragile but fluid entity, capable of effecting change upon the future evolution of humankind.

    In 2008 I chanced upon the lonely grave of Dr. William Theodore Hodge, buried in 1934, in the Derby Pioneer and Aboriginal Cemetery. He turned out to be the founding doctor of the practice in which I have worked for the past thirty years. Dr. Hodge migrated from England in 1896. He was the first western trained doctor to work in the Perth suburb of Claremont and in the wheat-belt town of Kellerberrin. He was an innovative and inventive modern doctor who became a legend in the Kimberley where he died tragically, on the day prior to his retirement, at the age of seventy-five. His story is illustrative of the life and medical practice of a pioneering doctor in metropolitan, rural, and remote practice in Western Australia at the end of the nineteenth and the early years of the twentieth centuries.

    The paper describes and analyzes original data, extracted from historical documents and scientific surveys, related to Russian fisheries in the southeastern part of the Gulf of Finland and its inflowing rivers during the 15- early 20th centuries. The data allow tracing key trends in fisheries development and in the abundance of major commercial species. In particular, results showed that, over time, the main fishing areas moved from the middle part of rivers downstream towards and onto the coastal sea. Changes in fishing patterns were closely interrelated with changes in the abundance of exploited fish. Anadromous species, such as Atlantic sturgeon, Atlantic salmon, brown trout, whitefish, vimba bream, smelt, lamprey, and catadromous eel were the most important commercial fish in the area because they were abundant, had high commercial value and were easily available for fishing in rivers. Due to intensive exploitation and other human-induced factors, populations of most of these species had declined notably by the early 20th century and have now lost commercial significance. The last sturgeon was caught in 1996, and today only smelt and lamprey support small commercial fisheries. According to historical sources, catches of freshwater species such as roach, ide, pike, perch, ruffe and burbot regularly occurred, in some areas exceeding half of the total catch, but they were not as important as migrating fish and no clear trends in abundance are apparent. Of documented marine catch, Baltic herring appeared in the 16th century, but did not become commercially significant until the 19th century. From then until now herring have been the dominant catch.

    This work uses a qualitative approach coupled with a quantitative software-based methodology to examine the Italian news media coverage of radiation in the early decades of the twentieth century. We analyze 80 news stories from two of the most influential Italian newspapers from that time: La Stampa (a daily newspaper) and La Domenica del Corriere (an Italian Sunday supplement). While much of previous research on media coverage of scientific topics was generally focused on present-day news, our work revolves around the ground-breaking discovery of X-rays and radioactivity at the dawn of the last century. Our analysis aims to identify journalistic frames in the news coverage of radiation that journalists might have used to emphasize the benefits (or the risks) of the new discoveries. We also hypothesize how this kind of news coverage might have influenced public perception of technological, commercial, and public health applications of the new scientific advancements. © The Author(s) 2014.

    During the XXth century, the evolution of histology in Romania was marked by different personalities. The aim of our paper is to present a parallel between two Professors of Histology: Alexandru Tupa (1886-1956) and Cornel Crisan (1895-1958) - who were contemporaries. Thus, we bring a homage to their memory, because in 2016 was the anniversary of 130 years since the birth of Al. Tupa and in 2018 will be the commemoration of 60 years since the death of C. Crisan. Both carried out their didactic and scientific activities at two prestigious Faculties of Medicine from Romania: Tupa in Jassy and Crisan in Cluj. Although they had a great respect one for the other, both of them progressing in the same morphological domain, yet it was not a close relationship between them. In our paper, we point out the numerous similarities regarding their lives and careers. The main resemblance between them, seen from a general perspective, is that they did not become unrivalled figures of the School of Medicine from Jassy, respectively from Cluj, even they were remarkable professors and scientists. In our article, we also mention their contribution to the development of histology in Romania.

    In the early 20th century, Harrison first performed renal decapsulation in anuric children with scarlet fever and observed improvement in renal function postoperatively. The pathophysiological explanation was seen in intraparenchymal renal pressure due to edema which was improved by surgical decapsulation. The technique of decapsulation was simple excision after incision and blunt dissection of the renal parenchyma. Renal decapsulation then became a procedure commonly used for many indications in inflammatory renal conditions; indications were renal angioneurosis, hydronephrosis, toxic, bacterial and chronic nephritis, renal abscess and even eclampsia. With the beginning of the antibiotic era, renal decapsulation became obsolete and has disappeared from the urological spectrum completely.

  7. Defining a discovery: priority and methodological controversy in early nineteenth-century anatomy

    2014-01-01

    In the early nineteenth century, Charles Bell and François Magendie engaged in a decades-long priority dispute over the discovery of the roots of motor and sensory nerves. The constantly recalibrated arguments of its participants illuminate changes in the life sciences during that period. When Bell first wrote about the nerves in 1811, surgeon-anatomists ran small schools out of their homes, natural theology was in vogue, exchanges between British and French medical practitioners were limited by the Napoleonic Wars, and British practitioners typically rejected experimental physiology and vivisection. By the end of Magendie's career, medical science was produced in the laboratory, taught through artfully produced performances of the sort at which Magendie excelled, and disseminated through journals. It is not entirely clear which historical character, Bell or Magendie, ‘won’ the dispute, nor that they even had clear and consistent positions in it, but what is clear is that one style of science had won out over the other, and over the course of the dispute, pedagogy lost pride of place in medical science.

    The molecular identification of proviruses from ancient tissues (and particularly from bones) remains a contentious issue. It can be expected that the copy number of proviruses will be low, which magnifies the risk of contamination with retroviruses from exogenous sources. To assess the feasibility of paleoretrovirological studies, we attempted to identify proviruses from early 20th century bones of museum specimens while following a strict ancient DNA methodology. Simian T-cell leukemia virus type 1 sequences were successfully obtained and authenticated from a Chlorocebus pygerythrus specimen. This represents the first clear evidence that it will be possible to use museum specimens to better characterize simian and human T-tropic retrovirus genetic diversity and analyze their origin and evolution, in greater detail.

    Historical reviews suggest that tanning first became fashionable in the 1920s or 1930s. To quantitatively and qualitatively examine changes in tanning attitudes portrayed in the popular women's press during the early 20th century, we reviewed summer issues of Vogue and Harper's Bazaar for the years 1920, 1927, 1928, and 1929. We examined these issues for articles and advertisements promoting skin tanning or skin bleaching and protection. We found that articles and advertisements promoting the fashionable aspects of tanned skin were more numerous in 1928 and 1929 than in 1927 and 1920, whereas those promoting pale skin (by bleaching or protection) were less numerous. These findings demonstrate a clear shift in attitudes toward tanned skin during this period. PMID:19846688

    This article uses textbooks and advertisements to explore the formal and informal ways in which people were introduced to vertical filing in the early twentieth century. Through the privileging of "system" an ideal mode of paperwork emerged in which a clerk could "grasp" information simply by hand without having to understand or comprehend its content. A file clerk's hands and fingers became central to the representation and teaching of filing. In this way, filing offered an example of a distinctly modern form of information work. Filing textbooks sought to enhance dexterity as the rapid handling of paper came to represent information as something that existed in discrete units, in bits that could be easily extracted. Advertisements represented this mode of information work in its ideal form when they frequently erased the worker or reduced him or her to hands, as "instant" filing became "automatic" filing, with the filing cabinet presented as a machine.

    Specialists of the history of hysteria know the name of Jean-Louis Brachet (1789-1858), but few realise the influence of this physician and surgeon from Lyon, a city in the southeastern part of France. Not only a clinician, he was also a neurophysiology researcher in the early 19th century. Along with his descriptions of meningoencephalitis, including hydrocephalus and meningoencephalitis, he elucidated the functioning of the vegetative nervous system and described its activity during emotional states. He also helped describe the different forms of epilepsy and sought to understand their aetiologies, working at the same time as the better-known Louis-Florentin Calmeil (1798-1895).

    Handwritten texts carry significant information, extending beyond the meaning of their words. Modern neurology, for example, benefits from the interpretation of the graphic features of writing and drawing for the diagnosis and monitoring of diseases and disorders. This article examines how handwriting analysis can be used, and has been used historically, as a methodological tool for the assessment of medical conditions and how this enhances our understanding of historical contexts of writing. We analyze handwritten material, writing tests and letters, from patients in an early 20th-century psychiatric hospital in southern Germany (Irsee/Kaufbeuren). In this institution, early psychiatrists assessed handwriting features, providing us novel insights into the earliest practices of psychiatric handwriting analysis, which can be connected to Berkenkotter's research on medical admission records. We finally consider the degree to which historical handwriting bears semiotic potential to explain the psychological state and personality of a writer, and how future research in written communication should approach these sources.

    Early nineteenth century Brazil saw a vibrant movement to study nature, including a number of expeditions aimed at gathering a corpus of knowledge on Brazilian flora. One of the main goals of these expeditions was to map and identify plant species of economic and therapeutic value. The government undertook and sponsored various initiatives, and it was within this context that the Bahian voyager Antônio Moniz de Souza engaged in his activities. He traveled through areas of the Brazilian territory in the first decades of the nineteenth century, observing, cataloging, and collecting products from the three kingdoms, especially plants with medicinal powers. This study of Moniz de Souza pinpoints and analyzes important features in the exploration of nature and knowledge and the use of medicinal plants during this timeframe.

    The using possibility of paleolimnological analyses was considered with the documentation aim of acid-forming substances distant transfer on territory of Northern Fennoscandia. The Holocene and ancient interglacial lakes pH-and alkalinity trends, reconstructed by means of bottom sediments diatomic analyses, were studied. It has been made evident that the tendency to sharp changes of these data is revealed on final stages of interglacial periods. At that time the high amplitude of climatic changes with low periodicity is resulting in catastrophic changes of landscapes in the frames of water-catchments bodies. During the last millennium the climatic situation in the Northern Fennoscandia wasmore » changing repeatedly (Medieval Warm Epoch, Little Ice Age, the rise in temperature in 20-40`s of XXth century). In the Little Ice Age (XVI-XIX centuries) the decrease of average annual temperature and intensification of winds velocity have caused a rapid retreat of latitudinal and high-altitude forest boundaries, accompanied by sharp reconstruction of tundra-,forest-tundra-and northern taiga landscapes. These processes have accelerated due to the enforcement of economic activity which caused the destruction of vegetation cover (salt-working, and ship-building since the XIXth century, pasture of reindeer herds since the end of XIXth century). Acidifying of ground and surface waters in the current century could be caused by the increased entry of organic acids, as a result of plant residues decomposition. The decomposition process was activated in the end of XIXth - beginning of XXth century in connection with the rise of temperature and increase of precipitation. Thus, the trends in pH and alkalinity changes in this region can not be used as indicators of acid-forming substances atmospheric deposition increase.« less

    2004-01-15

    During the first half of the 19th century, warfare did not provide a background for a systematic analysis of spinal cord injury (SCI). Medical officers participating in the Peninsular and Crimean Wars emphasized the dismal prognosis of this injury, although authors of sketchy civil reports persuaded a few surgeons to operate on closed fractures. The American Medical and Surgical History of the War of the Rebellion was the first text to provide summary of results in 642 cases of gunshot wounds of the spine. The low incidence of this injury (0.26%) and the high mortality rate (55%) discouraged the use of surgery in these cases. Improvements in diagnoses and the introduction of x-ray studies in the latter half of the century enabled Sir G. H. Makins, during the Boer War, to recommend delayed intervention to remove bone or bullet fragments in incomplete injuries. The civil experiences of Elsberg and Frazier in the early 20th century promoted a meticulous approach to treatments, whereas efficient transport of injured soldiers during World War I increased the numbers of survivors. Open large wounds or cerebrospinal fluid leakage, signs of cord compression in recovering patients, delayed clinical deterioration, or intractable pain required surgical exploration. Wartime recommendations for urological and skin care prevented sepsis, and burgeoning pension systems provided specialized longterm rehabilitation. By the Armistice, the effective surgical treatment and postoperative care that had developed through decades of interaction between civil and military medicine helped reduce incidences of morbidity and dispel the hopelessness surrounding the combatant with an SCI.

  19. Medical confidentiality in the late nineteenth and early twentieth centuries: an Anglo-German comparison1

    2012-01-01

    Summary Professional secrecy of doctors became an issue of considerable medico-legal and political debate in the late nineteenth and early twentieth centuries in both Germany and England, although the legal preconditions for this debate were quite different in the two countries. While in Germany medical confidentiality was a legal obligation and granted in court, no such statutory recognition of doctors’ professional secrecy existed in England. This paper is a comparative analysis of medical secrecy in three key areas - divorce trials, venereal disease and abortion - in both countries. Based on sources from the period between c.1870 and 1939, our paper shows how doctors tried to define the scope of professional secrecy as an integral part of their professional honour in relation to important matters of public health.

    Throughout the development of literature on urban design theories, utopian thinking has played a crucial role as utopians were among the first designers. Many unrealized utopian projects such as The Radiant City, have presented a research laboratory and positive attempts for all architects, urban designers and theorists. In this essay, a utopian vision following under More’s and Jameson’s definitions is discussed, examining how the utopian vision of modernist and futuristic houses and cities emerged in the early twentieth century in response to several factors, what urban utopia aimed to represent, and how such version was represented in the built form and the urban landscapes.

    On the turn of the 60s and 70s of the XIX century as a result of social -economical transformations which had occurred in the Polish Kingdom, Lódź experienced extremely quick industrial and demographical progress. With the increase in the number of inhabitants, particularly from 80s, the dynamic changes were observed, resulting in the increase in the number of health- service workers in the private service including doctors, dentists, barber-surgeons, midwives and druggists. In the multinational and multireligious Lódz, among health service workers, beside Polish ones there was also staff of German and Jewish descent. In comparison with the private service, the municipal one consisting of only a few doctors, veterinary surgeons and barber-surgeons, was expanding much more slowly. This was a result of Russian sanitary administrations, interest at public health being limited to the minimum. The worsening sanitary-hygienic conditions were the manifestation of this, and in consequence-growing incidence and high death rate of Lódź community, especially from acute and chronic infectious diseases. Decisive role, in the fight against health menaces, fell to socially committed doctors, who were helped by dentists and druggists.

  6. Multi-decadal evolution of ice/snow covers in the Mont-Blanc massif (France)

    2017-04-01

    Dynamics and evolution of the major glaciers of the Mont-Blanc massif have been vastly studied since the XXth century. Ice/snow covers on steep rock faces as part of the cryosphere however remain poorly studied with only qualitative descriptions existing. The study of ice/snow covers is primordial to further understand permafrost degradation throughout the Mont-Blanc massif and to improve safety and prevention for mountain sports practitioners. This study focuses on quantifying the evolution of ice/snow covers surface during the past century using a specially developed monoplotting tool using Bayesian statistics and Markov Chain Monte Carlo algorithms. Combining digital elevation models and photographs covering a time-span of 110 years, we calculated the ice/snow cover surface for 3 study sites — North faces of the Tour Ronde (3792 m a.s.l.) and the Grandes Jorasses (4208 m a.s.l.) and Triangle du Tacul (3970 m a.s.l.) — and deduced the evolution of their area throughout the XXth century. First results are showing several increase/decrease periods. The first decrease in ice/snow cover surface occurs between the 1940's and the 1950's. It is followed by an increase up to the 1980's. Since then, ice/snow covers show a general decrease in surface which is faster since the 2010's. Furthermore, the gain/loss during the increase/decrease periods varies with the considered ice/snow cover, making it an interesting cryospheric entity of its own.

    Starting with two statements made by two great artists and witnesses of the XXth century - Joseph Brodsky and the Polish poet, Tadeusz Rozewicz - the author discusses the roots of our current moral crisis to which we ourselves bear witness: in the unchecked population explosion (Brodsky), and in the sinister legacy of World War II, the effects of which we witness on a daily basis (Rozewicz). The author recalls a third witness: Czeslaw Milosz, who wrote that the world's progress exhibits an inevitable tendency toward nihilism. In his discourse with the three statements mentioned, the author refers to certain XXth century intellectuals - Ortega y Gasset, Cardinal Joseph Ratzinger, Mircea Eliade, Herbert Read - who confirm and develop the thesis of man s spiritual fall and rejection of transcendence through technology. The author further illustrates his thesis with examples taken from the scientific research concerning IT, cloning, euthanasia, as well as from the world of the arts from the apocalyptic works of Hieronymous Bosch and Pieter Bruegel the Elder to the latest performers. He invokes a worldview which, by rejecting the metaphysics of man s birth, aging, and death, also rejects the judeo-christian taboo of the human body as a "dwelling place for the spirit" (porno festivals, exhibitions of human corpses by Prof. von Hagens in Germany).

  8. Evidence of Active Dune Sand on the Great Plains in the 19th Century from Accounts of Early Explorers

    1995-03-01

    Eolian sand is extensive over the Great Plains of North America, but is at present mostly stabilized by vegetation. Accounts published by early explorers, however, indicate that at least parts of dune fields in Nebraska, Colorado, Kansas, New Mexico, and Texas were active in the 19th century. Based on an index of dune mobility and a regional tree-ring record, the probable causes for these periods of greater eolian activity are droughts, accompanied by higher temperatures, which greatly lowered the precipitation-to-evapotranspiration ratio and diminished the cover of stabilizing vegetation. In addition, observations by several explorers, and previous historical studies, indicate that rivers upwind of Great Plains dune fields had shallow, braided, sandy channels, as well as intermittent flow in the 19th century. Wide, braided, sandy rivers that were frequently dry would have increased sand supplies to active dune fields. We conclude that dune fields in the Great Plains are extremely sensitive to climate change and that the potential for reactivation of stabilized dunes in the future is high, with or without greenhouse warming.

  9. An assemblage of science and home. The gendered lifestyle of Svante Arrhenius and early twentieth-century physical chemistry.

    PubMed

    Bergwik, Staffan

    2014-06-01

    This essay explores the gendered lifestyle of early twentieth-century physics and chemistry and shows how that way of life was produced through linking science and home. In 1905, the Swedish physical chemist Svante Arrhenius married Maja Johansson and established a scientific household at the Nobel Institute for Physical Chemistry in Stockholm. He created a productive context for research in which ideas about marriage and family were pivotal. He also socialized in similar scientific sites abroad. This essay displays how scholars in the international community circulated the gendered lifestyle through frequent travel and by reproducing gendered behavior. Everywhere, husbands and wives were expected to perform distinct duties. Shared performances created loyalties across national divides. The essay thus situates the physical sciences at the turn of the twentieth century in a bourgeois gender ideology. Moreover, it argues that the gendered lifestyle was not external to knowledge making but, rather, foundational to laboratory life. A legitimate and culturally intelligible lifestyle produced the trust and support needed for collaboration. In addition, it enabled access to prestigious facilities for Svante Arrhenius, ultimately securing his position in international physical chemistry.

    Typhoid fever was the scourge of 19th- and early 20th-century armies. During the Spanish-American War (1898) and the Anglo-Boer War (1899- 1902), typhoid killed more soldiers than enemy bullets. Walter Reed and his coworkers investigated the cause of the typhoid epidemics in the U.S. Army camps and concluded that, next to human contact, the housefly (Musca domestica) was the most active agent in the spread of the disease. British medical officers in South Africa, facing even worse typhoid epidemics, reached the same conclusion. The experiences of the American and British armies finally convinced the medical profession and public health authorities that these insects conveyed typhoid. The housefly was now seen as a health menace. Military and civilian sanitarians waged fly-eradication campaigns that prevented the housefly's access to breeding places (especially human excrement), and that protected food and drink from contamination. Currently, M. domestica is recognized as the mechanical vector of a wide variety of viral, bacterial, and protozoal pathogens. Fly control is still an important public health measure in the 21st century, especially in developing countries.

  11. Has psychology "found its true path"? Methods, objectivity, and cries of "crisis" in early twentieth-century French psychology.

    PubMed

    Carson, John

    2012-06-01

    This article explores how French psychologists understood the state of their field during the first quarter of the twentieth century, and whether they thought it was in crisis. The article begins with the Russian-born psychologist Nicolas Kostyleff and his announcement in 1911 that experimental psychology was facing a crisis. After briefly situating Kostyleff, the article examines his analysis of the troubles facing experimental psychology and his proposed solution, as well as the rather muted response his diagnosis received from the French psychological community. The optimism about the field evident in many of the accounts surveying French psychology during the early twentieth century notwithstanding, a few others did join Kostyleff in declaring that all was not well with experimental psychology. Together their pronouncements suggest that under the surface, important unresolved issues faced the French psychological community. Two are singled out: What was the proper methodology for psychology as a positive science? And what kinds of practices could claim to be objective, and in what sense? The article concludes by examining what these anxieties reveal about the type of science that French psychologists hoped to pursue. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The large Juneau and Stikine icefields (Alaska) lost mass rapidly in the second part of the 20th century. Laser altimetry, gravimetry and field measurements suggest continuing mass loss in the early 21st century. However, two recent studies based on time series of Shuttle Radar Topographic Mission (SRTM) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) digital elevation models (DEMs) indicate a slowdown in mass loss after 2000. Here, the ASTER-based geodetic mass balances are recalculated carefully avoiding the use of the SRTM DEM because of the unknown penetration depth of the C-band radar signal. We find strongly negative mass balances from 2000 to 2016 (-0.68 ± 0.15 m w.e. a-1 for the Juneau Icefield and -0.83 ± 0.12 m w.e. a-1 for the Stikine Icefield), in agreement with laser altimetry, confirming that mass losses are continuing at unabated rates for both icefields. The SRTM DEM should be avoided or used very cautiously to estimate glacier volume change, especially in the North Hemisphere and over timescales of less than ˜ 20 years.

    The Columbian Exchange resulted in a widespread movement of humans, plants and animals between the Old and New Worlds. The late 15th to early 16th century transfer of cattle from the Iberian Peninsula and Canary Islands to the Caribbean laid the foundation for the development of American creole cattle (Bos taurus) breeds. Genetic analyses of modern cattle from the Americas reveal a mixed ancestry of European, African and Indian origins. Recent debate in the genetic literature centers on the ‘African’ haplogroup T1 and its subhaplogroups, alternatively tying their origins to the initial Spanish herds, and/or from subsequent movements of taurine cattle through the African slave trade. We examine this problem through ancient DNA analysis of early 16th century cattle bone from Sevilla la Nueva, the first Spanish colony in Jamaica. In spite of poor DNA preservation, both T3 and T1 haplogroups were identified in the cattle remains, confirming the presence of T1 in the earliest Spanish herds. The absence, however, of “African-derived American” haplotypes (AA/T1c1a1) in the Sevilla la Nueva sample, leaves open the origins of this sub-haplogroup in contemporary Caribbean cattle.

    Gallbladder cancer (GBC) is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    Acromegaly was first described by Pierre Marie in 1886. Some years later, it became clear that acromegaly and gigantism share the same etiology: GH hypersecretion due to a pituitary adenoma, induces gigantism if already present during puberty, or an acromegalic if it appears only during the adulthood. During the XXth century, the disease has been well described and is now well controlled with several treatments. Recently, genetic alterations responsible for the disease have been elucidated.

    While the global carbon budget (GCB) is relatively well constrained over the last decades of the 20th century [1], observations and reconstructions of atmospheric CO2 growth rate present large discrepancies during the earlier periods [2]. The large uncertainty in GCB has been attributed to the land biosphere, although it is not clear whether the gaps between observations and reconstructions are mainly because land-surface models (LSMs) underestimate inter-annual to decadal variability in natural ecosystems, or due to inaccuracies in land-use change reconstructions. As Eurasia encompasses about 15% of the terrestrial surface, 20% of the global soil organic carbon pool and constitutes a large CO2 sink, we evaluate the potential contribution of natural and human-driven processes to induce large anomalies in the biospheric CO2 fluxes in the early 20th century. We use an LSM specifically developed for high-latitudes, that correctly simulates Eurasian C-stocks and fluxes from observational records [3], in order to evaluate the sensitivity of the Eurasian sink to the strong high-latitude warming occurring between 1930 and 1950. We show that the LSM with improved high-latitude phenology, hydrology and soil processes, contrary to the group of LSMs in [2], is able to represent enhanced vegetation growth linked to boreal spring warming, consistent with tree-ring time-series [4]. By compiling a dataset of annual agricultural area in the Former Soviet Union that better reflects changes in cropland area linked with socio-economic fluctuations during the early 20th century, we show that land-abadonment during periods of crisis and war may result in reduced CO2 emissions from land-use change (44%–78% lower) detectable at decadal time-scales. Our study points to key processes that may need to be improved in LSMs and LUC datasets in order to better represent decadal variability in the land CO2 sink, and to better constrain the GCB during the pre-observational record.

    Many in dental education are unfamiliar with the professional life and thought of Dr. Alfred Owre, a distinguished though controversial dental educator in the early twentieth century. Owre served as dean of dentistry at both the University of Minnesota, 1905-27, and Columbia University, 1927-33. He was also a member of the Carnegie Foundation's commission that developed the report Dental Education in the United States and Canada, written by Dr. William J. Gies. Owre was a controversial leader due to his creative and original ideas that challenged dental education and the profession. His assessment and critique of the problems of dental education in his era can readily be applied to contemporary dental education and the profession, just as his vision for transformative change resonates with ideas that continue to be advocated by some individuals today. This article also documents his tumultuous relationship with Gies.

  3. The Nineteenth-Century Revolution in Astronomy

    2015-08-01

    The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

    2010-01-01

    As Milwaukee’s chief park planner in the early to mid-twentieth century, Charles Whitnall responded to the various underlying ideologies of the period within which he worked. His preference for parks was a political and physical response to and remedy for the industrialized and heavily congested city he called home. By examining the Progressive Era discourse associated with planning, this article situates Whitnall’s work within the political, aesthetic, and environmental contexts of geographic thought that influenced his plans for Milwaukee. In promoting a physical awareness associated with the natural features of the region and responding to the sociopolitical framework of contemporaries such as Ebenezer Howard, Whitnall incorporated a sense of compassion within his planning. He responded to the preexisting beer gardens of Pabst and Schlitz, as well as Olmsted-designed park spaces, by advocating for decentralization as part of a broader socialist agenda that had swept through Milwaukee during the early 1900s.

    Hirschman, Charles

    2005-11-01

    The full impact of immigration on American society is obscured in policy and academic analyses that focus on the short-term problems of immigrant adjustment. With a longer-term perspective, which includes the socioeconomic roles of the children of immigrants, immigration appears as one of the defining characteristics of twentieth-century America. Major waves of immigration create population diversity with new languages and cultures, but over time, while immigrants and their descendants become more "American," the character of American society and culture is transformed. In the early decades of the twentieth century, immigrants and their children were the majority of the workforce in many of the largest industrial cities; in recent decades, the arrival of immigrants and their families has slowed the demographic and economic decline of some American cities. The presence of immigrants probably creates as many jobs for native-born workers as are lost through displacement. Immigrants and their children played an important role in twentieth-century American politics and were influential in the development of American popular culture during the middle decades of the twentieth century. Intermarriage between the descendants of immigrants and old-stock Americans fosters a national identity based on civic participation rather than ancestry.

    Observed and modeled patterns of lower stratospheric seasonal trends in Antarctic ozone and temperature in the late 20th (1979-2000) and the early 21st (2000-2014) centuries are compared. Patterns of pre-2000 observed Antarctic ozone decreases and stratospheric cooling as a function of month and pressure are followed by opposite-signed (i.e., "mirrored") patterns of ozone increases and warming post-2000. An interactive chemistry-climate model forced by changes in anthropogenic ozone depleting substances produces broadly similar mirrored features. Statistical analysis of unforced model simulations (from long-term model control simulations of a few centuries up to 1000 years) suggests that internal and solar natural variability alone is unable to account for the pattern of observed ozone trend mirroring, implying that forcing is the dominant driver of this behavior. Radiative calculations indicate that ozone increases have contributed to Antarctic warming of the lower stratosphere over 2000-2014, but dynamical changes that are likely due to internal variability over this relatively short period also appear to be important. Overall, the results support the recent finding that the healing of the Antarctic ozone hole is underway and that coupling between dynamics, chemistry, and radiation is important for a full understanding of the causes of observed stratospheric temperature and ozone changes.

  9. New Early Cycladic Figurine At Nea Styra

    Kosma, M.

    The existence of an Early Bronze Age coastal site in the district of Nea Styra has been known since the end of the 19th century when three marble figurines of early Cycladic type had been found in the area. During the 20th century survey investigations conducted by Greek and foreign archaeologists offered new evidence which demonstrated the significance of the site during the Early and Middle Helladic periods. A new figurine of early Cycladic type, which recently came to light at Nea Styra due to the control of building permits by the 11th Ephorate of Prehistoric and Classical Antiquities, reaffirms the identification of the area as one of the three most important sites on Euboea during the Early Helladic II period. This paper focuses on a newly discovered figurine and its typological character. The new find is compared to the figurines that had been found in the 19th century at Nea Styra. We hope that the scheduled excavations on the private land plot where the new figurine was found will offer new data leading to a better understanding of the character of the Early Helladic settlement in this part of southern Euboea.

    Great Lakes forests were subject to a severe pulse of disturbance from the mid-19th century through the early 20th century that resulted from extensive harvesting and subsequent fires following European settlement. Today?s forest, in many ways, is exhibiting changes in area and demography that reflect recovery from this pulse of disturbance, as well as response to...

  12. Techniques for nothingness: Debate over the comparability of hypnosis and Zen in early-twentieth-century Japan.

    PubMed

    Wu, Yu-Chuan

    2017-12-01

    This paper explores a debate that took place in Japan in the early twentieth century over the comparability of hypnosis and Zen. The debate was among the first exchanges between psychology and Buddhism in Japan, and it cast doubt on previous assumptions that a clear boundary existed between the two fields. In the debate, we find that contemporaries readily incorporated ideas from psychology and Buddhism to reconstruct the experiences and concepts of hypnosis and Buddhist nothingness. The resulting new theories and techniques of nothingness were fruits of a fairly fluid boundary between the two fields. The debate, moreover, reveals that psychology tried to address the challenges and possibilities posed by religious introspective meditation and intuitive experiences in a positive way. In the end, however, psychology no longer regarded them as viable experimental or psychotherapeutic tools but merely as particular subjective experiences to be investigated and explained.

  13. In the laboratory of the Ghost-Baron: parapsychology in Germany in the early 20th century.

    PubMed

    Wolffram, Heather

    2009-12-01

    During the early twentieth century the Munich-based psychiatrist Albert von Schrenck-Notzing constructed a parapsychological laboratory in his Karolinenplatz home. Furnished with a range of apparatus derived from the physical and behavioural sciences, the Baron's intention was to mimic both the outward form and disciplinary trajectory of contemporary experimental psychology, thereby legitimating the nascent field of parapsychology. Experimentation with mediums, those labile subjects who produced ectoplasm, materialisation and telekinesis, however, necessitated not only the inclusion of a range of spiritualist props, but the lackadaisical application of those checks and controls intended to prevent simulation and fraud. Thus Schrenck-Notzing's parapsychological laboratory with its stereoscopic cameras, galvanometers and medium cabinets was a strange coalescence of both the séance room and the lab, a hybrid space that was symbolic of the irresolvable epistemological and methodological problems at the heart of this aspiring science.

  14. Modeling and Reality in Early Twentieth-Century Physics

    2011-04-01

    Towards the end of 1913, Arnold Sommerfeld, Professor of theoretical physics at Munich University, sent a letter of congratulations to a young Niels Bohr. The Dane's now-classic trilogy of papers, which coupled Rutherford's conception of the atom with a ``planetary'' configuration of electrons, had just appeared. Sommerfeld saw the calculation of the Rydberg constant as a singular triumph and immediately spotted an opportunity to try to explain the Zeeman effect. Yet he also sounded a note of caution, confessing that he remained ``somewhat skeptical'' of atomic models in general. In this, of course, he was hardly alone. Bohr's atom was a particularly egregious example of a peculiar model, one requiring what even its creator considered ``horrid assumptions.'' Nonetheless, success bred conviction. Expanding upon Bohr's original ideas, Sommerfeld soon produced the so-called ``Bohr-Sommerfeld quantization conditions,'' using them to calculate a myriad of results. Experimental evidence, Sommerfeld argued in 1915, showed that quantised electron-paths ``correspond exactly to reality'' and possess ``real existence.'' This kind of realism would not, of course, last long. In 1925, Werner Heisenberg (earlier a student of Sommerfeld's) made scepticism about the details of the Bohr model into a methodological dictum, one later enshrined in the ``Copenhagen interpretation'' of quantum mechanics. This paper uses Sommerfeld's work from the turn of the twentieth century to the mid-1920s as a window onto a landscape involving multiple contestations over the legitimacy of atomic modelling. The surprise that greeted Heisenberg's and others' phenomenological insistences, we will see, can only be understood with reference to what should be considered a ``realist interlude'' in the history of twentieth century atomic physics, one inspired by the astonishing successes of Rutherford's and Bohr's imaginings.

    2017-12-01

    The latter half of the 20th century and the early portion of the 21st century will be recognized as the "Golden Age" of lactation biology. This period corresponded with the rise of systemic, metabolomic, molecular, and genomic biology. It includes the discovery of the structure of DNA and ends with the sequencing of the complete genomes of humans and all major domestic animal species including the dairy cow. This included the ability to identify polymorphisms in the nucleic acid sequence, which can be tied to specific differences in cellular, tissue, and animal performance. Before this period, classical work using endocrine ablation and replacement studies identified the mammary gland as an endocrine-dependent organ. In the early 1960s, the development of RIA and radioreceptor assays permitted the study of the relationship between endocrine patterns and mammary function. The ability to measure nucleic acid content of tissues opened the door to study of the factors regulating mammary growth. The development of high-speed centrifugation in the 1960s allowed separation of specific cell organelles and their membranes. The development of transmission and scanning electron microscopy permitted the study of the relationship between structure and function in the mammary secretory cell. The availability of radiolabeled metabolites provided the opportunity to investigate the metabolic pathways and their regulation. The development of concepts regarding the coordination of metabolism to support lactation integrated our understanding of nutrient partitioning and homeostasis. The ability to produce recombinant molecules and organisms permitted enhancement of lactation in farm animal species and the production of milk containing proteins of value to human medicine. These discoveries and others contributed to vastly increased dairy farm productivity in the United States and worldwide. This review will include the discussion of the centers of excellence and scientists who labored

  16. Composition of Façon de Venise glass from early 17th century London in comparison with luxury glass of the same age

    NASA Astrophysics Data System (ADS)

    Cagno, S.; De Raedt, I.; Jeffries, T.; Janssens, K.

    SEM-EDX and LA-ICP-MS analyses were performed on a set of early 17th century London glass fragments. The samples originate from two archaeological sites (Aldgate and Old Broad Street) where glass workshops were active in this period. The great majority of the samples are made of soda glass. Two distinct compositional groups are observed, each typical of one site of provenance. The samples originating from the Old Broad Street excavation feature a silica-soda-lime composition, with a moderate amount of potash. The samples from Aldgate are richer in potassium and feature higher amounts of trace elements such as Rb, Zr and Cu. The distinction between the two groups stems from different flux and silica sources used for glassmaking. A comparison with different European glass compositions of that time reveals no resemblance with genuine Venetian production, yet the composition of the Old Broad Street glass shows a close similarity to that of fragments produced `à la façon de Venise' in Antwerp at the end of the 16th century. This coincides with historical sources attesting the arrival of glassworkers from the Low Countries in England and suggests that a transfer of technology took place near the turn of the century.

    Although homosexuality was considered to be a crime in nineteenth-century England, the subculture of the school system promoted it. For example, in the early nineteenth century schoolboys of all ages were locked up in dormitories at 8:00 p.m. and no master entered the building until the next morning. No-one supervised the boys' activities during…

  18. 14th-16th century Danube floods and long-term water-level changes reflected in archaeological-sedimentary evidence - in comparison with documentary evidence

    NASA Astrophysics Data System (ADS)

    Kiss, Andrea; Laszlovszky, József

    2014-05-01

    In the present paper an overview of published and unpublished results of archaeological and sedimentary investigations, predominantly reflect on 14th-16th-century changes, are provided and compared to documentary information on flood events and long-term changes. Long-term changes in flood behaviour and average water-level conditions had long-term detectable impacts on sedimentation and fluvio-morphological processes. Moreover, the available archaeological evidence might also provide information on the reaction of the society, in the form of changes in settlement organisation, building structures and processes. At present, information is mainly available concerning the 16th, and partly to the 14th-15th centuries. Medium and short term evidence mainly corresponds to the main flood peaks or even to single catastrophic flood events. Such processes may be identified in archaeological evidence concerning the second half of the 14th, early 15th centuries; while most of the cases listed above were connected to the flood peak (and/or generally increasing water-level conditions) of the late 15th and early 16th centuries. In other cases connections between sedimentary/archaeological evidence and the mid- and late 16th-century high flood-frequency period were presumed. Documentary evidence referring to the same period suggests that higher flood frequency and intensity periods occurred in the early and mid 16th century; a probably more prolonged flood rich period took place in the second half of the 16th century, with a peak in the late 1560s-early 1570s and maybe with another at the end of the 16th century. Earlier flood peaks in documentary evidence were detected on the Danube at the turn of the 14th-15th centuries and in the last decades of the 15th century, continuing in the early 16th century.

    Lundberg, A

    2001-01-01

    In the early twentieth century a wider debate took place about how Swedish society was to fight the spread of contagious venereal diseases and in 1910 a government committee had written a law proposal that would dramatically reform these measures previously, Swedish physicians had been united against any measures against these diseases that did not involve the regulation of prostitutes, but this consensus was slowly withering away in the early parts of the century. Female doctors and a younger generation of venereologists was drawing the conclusion that mandatory checks of only one out of two sexes was insufficient. This article reviews the debate regarding the regulation of prostitution that took place between conservative and liberal members in the Swedish Medical Association in 1911. It depicts a fierce discussion between members that still clung to nineteenth-century ideas of women as being prone to prostitution if left idle and unemployed, and liberal members that believed social injustices such as low wages laid behind women's decisions. The study gives an insight into the complexities of building the Swedish welfare state.

  20. Warm Arctic-cold Siberia: comparing the recent and the early 20th-century Arctic warmings

    Wegmann, Martin; Orsolini, Yvan; Zolina, Olga

    2018-02-01

    The Warm Arctic-cold Siberia surface temperature pattern during recent boreal winter is suggested to be triggered by the ongoing decrease of Arctic autumn sea ice concentration and has been observed together with an increase in mid-latitude extreme events and a meridionalization of tropospheric circulation. However, the exact mechanism behind this dipole temperature pattern is still under debate, since model experiments with reduced sea ice show conflicting results. We use the early twentieth-century Arctic warming (ETCAW) as a case study to investigate the link between September sea ice in the Barents-Kara Sea (BKS) and the Siberian temperature evolution. Analyzing a variety of long-term climate reanalyses, we find that the overall winter temperature and heat flux trend occurs with the reduction of September BKS sea ice. Tropospheric conditions show a strengthened atmospheric blocking over the BKS, strengthening the advection of cold air from the Arctic to central Siberia on its eastern flank, together with a reduction of warm air advection by the westerlies. This setup is valid for both the ETCAW and the current Arctic warming period.

    Early instrumental series are the main source for climate information in the 18th and the first part of the 19th century, which is when systematic meteorological observations started in most national meteorological services. The first continuous series in Spain starts in 1780 in Barcelona due to meteorological observations made by the medical doctor Francisco Salvá Campillo. Moreover, only two other series have been recovered at the present in Spain: Madrid and Cádiz/San Fernando. Until present, in Spain the major part of the meteorological observations detected in early instrumental periods were made by medical doctors, who started to pay attention to the environmental factors influencing population health under the Hippocrates oath, although also there are military institutions and academic university staff (e.g. physicists, mathematicians, etc.). Due to the high spatial and temporal climate variability in the Iberian Peninsula, it is important to recover and digitize more climatic series, and this is one of the main goals of the Salvá-Sinobas project (http://salva-sinobas.uvigo.es/) funded by the Spanish Ministry of Environment, and Rural and Marine Affairs for the 2009-2011 period. The first new series with systematic observations was detected in the city of Valencia, in the eastern façade of the Iberian Peninsula. The meteorological observations were daily published in the newspapers Diario de Valencia (1804-1834) and Diario Mercantil de Valencia (1837-1863) until official meteorological observations started in 1858 at the University of Valencia. Each day 3-daily observations (morning, midday, afternoon) were published with five climatic variables: temperature, air pressure, humidity, wind direction and the sky state. Only during the 1804-1808 period daily rainfall data is available. We checked the observer comments published in the newspapers to obtain metadata about the instruments and meteorological station information. Unfortunately, temperature data

    1986-11-01

    Among the most notable features of the religious revival in western Europe in the early thirteenth century was the development of mysticism among the nuns and religious women of the lowlands. As scholarly attention becomes increasingly focused on this group of remarkable women, the question arises whether a psychiatric viewpoint has something of value to offer to the understanding of such individuals and the culture in which they struggled. The methodological and intellectual problems inherent in examining the life of a thirteenth-century mystic with a twentieth-century empirical frame of reference are illustrated in this study of the adolescence of Beatrice of Nazareth. Beatrice's stormy asceticism, ecstatic states and mood swings lend themselves to potentially competing hypotheses regarding the spiritual and psychopathological significance of her adolescent development and eventual life-course. Common grounds for reconciling these alternative models are discussed.

  5. On the Causes and Dynamics of the Early Twentieth Century North American Pluvial

    NASA Technical Reports Server (NTRS)

    Cook, Benjamin I.; Seager, Richard; Miller, Ron L.

    2011-01-01

    The early twentieth century North American pluvial (1905-1917) was one of the most extreme wet periods of the last five hundred years and directly led to overly generous water allotments in the water-limited American West. Here we examine the causes and dynamics of the pluvial event using a combination of observation-based data sets and general circulation model (GCM) experiments. The character of the moisture surpluses during the pluvial differed by region, alternately driven by increased precipitation (the Southwest), low evaporation from cool temperatures (the Central Plains), or a combination of the two (the Pacific Northwest). Cool temperature anomalies covered much of the west and persisted through most months, part of a globally extensive period of cooler land and sea surface temperatures (SST). Circulation during boreal winter favored increased moisture import and precipitation in the southwest, while other regions and seasons were characterized by near normal or reduced precipitation. Anomalies in the mean circulation, precipitation, and SST fields are partially consistent with the relatively weak El Nino forcing during the pluvial, and also reflect the impact of positive departures in the Arctic Oscillation that occurred in ten of the thirteen pluvial winters. Differences between the reanalysis dataset, an independent statistical drought model, and GCM simulations highlight some of the remaining uncertainties in understanding the full extent of SST forcing of North American hydroclimatic variability.

    2013-01-01

    The 19th century was a period of momentous scientific discoveries, technological achievements, and societal changes. A beneficiary of these revolutionary upheavals was medical empiricism that supplanted the rationalism of the past giving rise to early modern scientific medicine. Continued reliance on sensory data now magnified by technical advances generated new medical information that could be quantified with increasing precision, verified by repeated experimentation, and validated by statistical analysis. The institutionalization and integration of these methodologies into medical education were a defining step that assured their progress and perpetuation. Major advances were made in the nosography of diseases of the kidney, notably that of the diagnosis of progressive kidney disease from the presence of albuminuria by Richard Bright (1789-1858); and of renal structure and function, notably the demonstration of the continuity of the glomerular capsule with the tubular basement membrane by William Bowman (1816-1892), and the arguments for hemodynamic physical forces mediated glomerular filtration by Carl Ludwig (1816-1895) and for active tubular transport by Rudolf Heidenhain (1834-1897). Improvements in microscopy and tissue processing were instrumental in describing the cellular ultrastructure of the glomerulus and tubular segments, but their integrated function remained to be elucidated. The kidney continued to be considered a tubular secretory organ and its pathology attributed to injury of the interstitium (interstitial nephritis) or tubules (parenchymatous nephritis). © 2012 Wiley Periodicals, Inc.

    2013-05-01

    The paucity of available instrumental climate records in cold and arid regions of the western Himalaya, India, hampers our understanding of the long-term variability of regional droughts, which seriously affect the agrarian economy of the region. Using ring width chronologies of Cedrus deodara and Pinus gerardiana together from a network of moisture-stressed sites, Palmer Drought Severity Index values for October-May back to 1310 A.D. were developed. The twentieth century features dominant decadal-scale pluvial phases (1981-1995, 1952-1968, and 1918-1934) as compared to the severe droughts in the early seventeenth century (1617-1640) as well as late fifteenth to early sixteenth (1491-1526) centuries. The drought anomalies are positively (negatively) associated with central Pacific (Indo-Pacific Warm Pool) sea surface temperature anomalies. However, non-stationarity in such relationships appears to be the major riddle in the predictability of long-term droughts much needed for the sustainable development of the ecologically sensitive region of the Himalayas.

    2003-01-01

    American eugenists in the early 20th century distinguished "degenerates," including syphilitics, prostitutes, alcoholics and criminals, from the "normal" population by their particular bad habits. From eugenists' viewpoint, these bad habits were derived from bad character, a flaw that stemmed from an individual's bad genes. This essay explores how eugenists during this period characterized syphilitics and those with associated character "defects" in terms of heredity. Additionally, it examines the methods eugenists most frequently advocated to rectify these bad habits. These methods included marriage restriction, immigration control and reproductive sterilization. Overall, eugenists directed their efforts not so much at the "degenerate" as at his or her germ line.

    Federally funded remedial action projects are presently underway in New Jersey and Colorado at sites containing 226Ra and other radionuclides from radium-uranium ore extraction plants that operated during the early twentieth century. They are but the latest chapter in the story of an American industry that emerged and perished in the span of three decades. Major extraction plants were established in or near Denver (CO), Pittsburgh (PA), and New York City (NY) to process radium from ore that came largely from the carnotite deposits of western Colorado and eastern Utah. The staffs of these plants included some of the finest chemists and physicists in the nation, and the highly-refined radium products found a variety of uses in medicine and industry. The discovery of high-grade pitchblende ores in the Belgian Congo and the subsequent opening of an extraction plant near Antwerp, Belgium, in 1992, however, created an economic climate that put an end to the American radium industry. The geologic, chemical, and engineering information gathered during this era formed the basis of the uranium industry of the later part of the century, while the tailings and residues came to be viewed as environmental problems during the same period.

    Mercury has a long history, fascinating in its many aspects. Through the centuries--from ancient times to the present day--the metal in its various forms, also known under the name "quicksilver", accompanied the man and was used for diversified purposes. Today, mercury is employed in manufacturing thermometers, barometers, vacuum pumps and explosives. It is also used in silver and gold mining processes. Mercury compounds play a significant role in dentistry, pharmaceutical industry and crop protection. The contemporary use of mercury markedly decreases, but historically speaking, the archives abound in materials that document facts and events occurring over generations and the immense intellectual effort aiming at discovering the true properties and mechanisms of mercury activity. Mercury toxicity, manifested in destruction of biological membranes and binding of the element with proteins, what disturbs biochemical processes occurring in the body, was discovered only after many centuries of the metal exerting its effect on the lives of individuals and communities. For centuries, mercury was present in the work of alchemists, who searched for the universal essence or quintessence and the so-called philosopher's stone. In the early modern era, between the 16th and 19th centuries, mercury was used to manufacture mirrors. Mercury compounds were employed as a medication against syphilis, which plagued mankind for more than four hundred years--from the Middle Ages till mid 20th century, when the discovery of penicillin became the turning point. This extremely toxic therapy resulted in much suffering, individual tragedies, chronic poisonings leading to fatalities and dramatic sudden deaths. In the last fifty years, there even occurred attempts of mentally imbalanced individuals at injecting themselves with metallic mercury, also as a performance-enhancing drug. Instances of mass mercury poisoning occurred many times in the past in consequence of eating food products

    Little is known about late 19th and early 20th century BMIs on the US Central Plains. Using data from the Nebraska state prison, this study demonstrates that the BMIs of dark complexioned blacks were greater than for fairer complexioned mulattos and whites. Although modern BMIs have increased, late 19th and early 20th century BMIs in Nebraska were in normal ranges; neither underweight nor obese individuals were common. Farmer BMIs were consistently greater than those of non-farmers, and farm labourer BMIs were greater than those of common labourers. The BMIs of individuals born in Plains states were greater than for other nativities, indicating that rural lifestyles were associated with better net current biological living conditions.

  14. Fumigating the Hygienic Model City: Bubonic Plague and the Sulfurozador in Early-Twentieth-Century Buenos Aires.

    PubMed

    Engelmann, Lukas

    2018-07-01

    The 1899/1900 arrival of bubonic plague in Argentina had thrown the model status of Buenos Aires as a hygienic city into crisis. Where the idea of foreign threats and imported epidemics had dominated the thinking of Argentina's sanitarians at that time, plague renewed concerns about hidden threats within the fabric of the capital's dense environment; concerns that led to new sanitary measures and unprecedented rat-campaigns supported by the large-scale application of sulphur dioxide. The article tells the story of early twentieth-century urban sanitation in Buenos Aires through the lens of a new industrial disinfection apparatus. The Aparato Marot, also known as Sulfurozador was acquired and integrated in the capital's sanitary administration by the epidemiologist José Penna in 1906 to materialise two key lessons learned from plague. First, the machine was supposed to translate the successful disinfection practices of global maritime sanitation into urban epidemic control in Argentina. Second, the machine's design enabled public health authorities to reinvigorate a traditional hygienic concern for the entirety of the city's terrain. While the Sulfurozador offered effective destruction of rats, it promised also a comprehensive - and utopian - disinfection of the whole city, freeing it from all imaginable pathogens, insects as well as rodents. In 1910, the successful introduction of the Sulfurozador encouraged Argentina's medico-political elite to introduce a new principle of 'general prophylaxis'. This article places the apparatus as a technological modernisation of traditional sanitary practices in the bacteriological age, which preserved the urban environment - 'el terreno' - as a principal site of intervention. Thus, the Sulfurozador allowed the 'higienistas' to sustain a long-standing utopian vision of all-encompassing social, bodily and political hygiene into the twentieth century.

    The Google Ngram Viewer shows the frequency of words in a large corpus of books over two centuries. In this study, the names of two pseudosciences, astrology and phrenology, were compared. An interesting pattern emerged. While the level of interest in astrology remained relatively stable over the course of two centuries, interest in phrenology rose rapidly in the early 1800s but then declined. Reasons for this pattern are discussed.

  17. How to manage a revolution: Isaac Newton in the early twentieth century

    PubMed Central

    Clarke, Imogen

    2014-01-01

    In the first half of the twentieth century, dramatic developments in physics came to be viewed as revolutionary, apparently requiring a complete overthrow of previous theories. British physicists were keen to promote quantum physics and relativity theory as exciting and new, but the rhetoric of revolution threatened science's claim to stability and its prestigious connections with Isaac Newton. This was particularly problematic in the first decades of the twentieth century, within the broader context of political turmoil, world war, and the emergence of modernist art and literature. This article examines how physicists responded to their cultural and political environment and worked to maintain disciplinary connections with Isaac Newton, emphasizing the importance of both the old and the new. In doing so they attempted to make the physics ‘revolution’ more palatable to a British public seeking a sense of permanence in a rapidly changing world.

    The concept of "illness's social course" can be approached from two stand-points. We can trace both the way the social world shapes the course of an illness and the way an illness' symptoms shape the social world. The purpose of this study is to locate the specific illness of love melancholy in a specific historical and social context, namely that of France and England in the late sixteenth and early seventeenth centuries, in order to explain the intense discussion on the disorder during that period. This attempt is done with respect to the two dimensions of the concept of "illness' social course" and in the light of constructivist commentary on psychological disorders, which regards them as local stress idioms shaped by a specific social and cultural context.

    From the perspective of the science of astronomy, the interpretation of the light spectrum was a fundamental development in the chemical analysis of celestial starlight. The breakthrough discovery with the application of spectroscopy in 1859, inaugurated a new period in astronomy that evolved into astrophysics. It launched a continuing episode of new astronomy that was later embraced in early 20th-century Canada where it was spearheaded by Canadian physicist and scientist, John S. Plaskett (1865-1941). The research work of John Plaskett at the Dominion Observatory in Ottawa, Ontario, from 1903 and, later, the Dominion Astrophysical Observatory in Victoria, British Columbia, from 1918, brought international recognition to Canada’s early efforts in astrophysics. Plaskett’s determination and personal boldness led to the establishment of a small cadre of Canadian astronomers who worked on their astrophysical research programs under Plaskett as their supervisor. Despite its small population at the time and a relatively infinitesimal number of professional astronomers, Canada did become recognized for its early spectrographic work in astrophysics, which was due to developing a professional status equal to its international colleagues. Plaskett improved the techniques of celestial spectroscopy during his scientific work at the Dominion Observatory and, again later, at its newly-built sister facility, the Dominion Astrophysical Observatory. Historically, Plaskett found himself to be the right person, in the right place, at the right time, and with the right temperament during the review period spanning 1903 to 1935.

    The article considers activity of municipal self-governments of Russia concerning support of sanitary epidemiological well-being of cities in the late XIX--early XX centuries. The acuteness of problem of sanitary conditions of urban settlements particularly became visible in post-reform period due to increasing of number of urban population, alteration of setup and rhythm of life in cities, appearance of new forms of worker's daily chores. Al this, against the background of underdevelopment of communal sphere aggravated epidemiological situation in cities. The impulse to improvement and development of sanitary control was made by the city regulations of 1870 presenting to town authorities the right to deal with sanitary issues. The significant input into improvement of cities was made first of all at the expense of construction of water supplies and sewerage and support of sanitary control of these spheres of municipal economy. Under town councils of many cities the sanitary commissions were organized to support permanent sanitary control in town. The development of town sanitation followed the way of specialization. The housing and communal, trade and food, school and sanitary and sanitary and veterinary control were organized.

    Only selected aspects of the history of the House of the Poor Insane in the Hanseatic Free City of Lübeck have been studied to date.This article presents the results of an entire source study of this small institution in the 17th and 18th centuries, and briefly also during the next 40 years after the opening of a new building. In addition to the minute-book of the Governors, now kept in the Lübeck Municipal Archives, the results are based primarily on the account-books,which illustrate the institution's social history and activities. Examples are given. During most of the 17th century, the House was generally rather like a prison for the insane, but at the end of this century and in the early 18th there was a reform phase.This was followed by phases of repression and 'containment' at the end of the 18th century and in the early 19th century, before a renewed reform by the medical profession.The findings for Lübeck are compared with the development of inpatient care in institutions elsewhere, and the decisive factors in Lübeck are discussed.

  2. Empiricism and Rationalism in Nineteenth-Century Histories of Philosophy.

    2016-01-01

    This paper traces the ancestry of a familiar historiographical narrative, according to which early modern philosophy was marked by the development of empiricism, rationalism, and their synthesis by Kant. It is often claimed that this narrative became standard in the nineteenth century because of the influence of Thomas Reid, Kant and his disciples, or German and British idealists. I argue that the narrative became standard at the turn of the twentieth century. Among the factors that allowed it to become standard are its aptness to be adopted by philosophers of the most diverse persuasions, its simplicity and suitability for teaching.

    In the period 1909-1927, new laws concerning divorce and marriage were enacted by the Scandinavian countries. Both at the time and more recently, these laws were considered as "liberal" as they promoted greater freedom to divorce based on individuality and gender equality. In this article, the authors first analyze the changes in these Family laws in the early twentieth century. Then, the authors study the effect of these laws on divorce and marriage patterns. As these laws did not modify the trend in divorce rates, the authors ask why this was the case. The authors' conclusions are that the laws were more concerned with preserving the sanctity of marriage and maintaining social order than with promoting individual freedom and gender equality.

    A previous paper detailed the life and the works of Louis-Lazare Zamenhof (1857-1917), a young physician, born in Lituania, of Jewish origin, specialiazed in ophtalmology. Zamenhof created a new universal language he called "Esperanto". The study continues Zamenhof's biography, from 1905, date of the first international esperantist congress, at Boulogne-sur-Mer, in France to 1917, year of Zamenhof's death, during World War I. The paper will restitute Zamenhof's ideology in the history of the ideas of the XXth century, such as nationalisms, internationalism, pacifism and universalism of Human Right.

    2012-12-01

    Prejudice and stigma against people with mental illness can be seen throughout history. The worst instance of this prejudice was connected to the rise of the eugenics movement in the early 20th century. Although the Nazi German T-4 program of killing people with mental illness was the most egregious culmination of this philosophy, the United States has its own dark eugenics history-nearing a slippery slope all too similar to that of the Nazis. Mental health care clinicians need to examine this period to honor the memory of the victims of eugenics and to guarantee that nothing like this will ever happen again.

  7. Climate and history in the late 18th and early 19th centuries

    NASA Astrophysics Data System (ADS)

    Feldman, Theodore S.

    As in many areas of human knowledge, the notion of climate acquired a deeper historical content around the turn of the 19th century. Natural philosophers, geographers, and others became increasingly aware of climate's own history and its relation to human, plant and animal, and Earth history. This article examines several aspects of this “historicization” of climate.The lively 18th century discussion of the influence of climate on society is well known. Montesquieu is its most famous representative, but Voltaire, Hume, Kant, and others also participated. Their debate was literary more than scientific, their goal the understanding of man, not climate. Partly for this reason and partly because of the lack of good information on climates, they made no attempt to gather substantial climatic data. In fact, the importance of systematically collecting reliable data was scarcely understood in any area of natural philosophy before the last decades of the century [Cf. Frängsmyr et al., 1990; Feldman, 1990]. Instead, participants in the debate repeated commonplaces dating from Aristotle and Hippocrates and based their conclusions on unreliable reports from travelers. As Glacken wrote of Montesquieu, “his dishes are from old and well-tested recipes” [Glacken, 1967, chapter 12]. This is not to say that the debate over climatic influence was not significant—only that its significance lay more in the history of man than in the atmospheric sciences.

    2012-11-01

    In 1886, addressing the nascent American Society of Mechanical Engineers, Henry R. Towne proposed that "the management of works" be considered a modern art--thereby heralding the Management Century, when management as we know it came into being and shaped the world in which we work. Kiechel, a past editorial director of Harvard Business Publishing, elucidates the three eras that punctuate this period: the years leading up to World War II, during which scientific exactitude gave wings to a new managerial elite; the early postwar decades, managerialism's apogee of self-confidence and a time when wartime principles of strategy were adapted, sometimes ruthlessly, to the running of companies; and the 1980s to the present, years that saw fast-moving changes, disequilibrium, and a servitude to market forces but also ushered in globalism, unprecedented innovation, and heightened expectations about how workers are to be treated. Along the way he examines the contributions of thinkers such as Frederick Taylor, Elton Mayo, Peter Drucker, and Michael Porter. What lies ahead? Perhaps the biggest challenge facing the 21st-century company, Kiechel posits, is to truly free the spark of human imagination from the organization's tidal pull toward the status quo. There's almost always a better way, he concludes--and management will continue to seek it.

    Lee, Hye-Min

    2016-04-01

    This article aims to investigate the shaping of knowledge and discourse on ginseng, especially among physicians and botanists, since its introduction to France from the 17th century until the early 18th century. In France, knowledge on herbal medicine, including that of ginseng, was shaped under the influence of the modern state's policy and institution: mercantilism and the Académie royale des sciences. The knowledge of herbal medicine developed as an important part of the mercantilist policy supported systematically by the Académie. The East Asian ginseng, renowned as a panacea, was first introduced into France in the 17th century, initially in a roundabout way through transportation and English and Dutch publications of travel tales from various foreign countries. The publication activity was mainly conducted by Thévenot company with the intention to meet the needs of French mercantilism promoted by Colbert. It also implied interests on medicine in order to bolster the people's health. The Thévenot company's activity thus offered vital information on plants and herbs abroad, one of which was ginseng. Furthermore, with Louis XIV's dispatching of the Jesuit missionaries to East Asia, the Frenchmen were able to directly gather information on ginseng. These information became a basis for research of the Académie. In the Académie, founded in 1666 by Colbert, the king's physicians and botanists systematically and collectively studied on exotic plants and medical herbs including ginseng. They were also key figures of the Jardin du Roi. These institutions bore a striking contrast to the faculty of medicine at the University of Paris which has been a center of the traditional Galenic medicine. The research of the Académie on ginseng was greatly advanced, owing much to the reports and samples sent from China and Canada by Jartoux, Sarrazin, and Lapitau. From the early 18th century, the conservative attitude of the University of Paris, which was a stronghold of

    The study substantiates the approach to the assessment of impact of climate change on vital activities of population in Russia in the face of increasing climate extremes. The obtained results reveal the occurrence of the essential climate extreme events over the period 1991-2013 in Russia that are vital for population activities. Annual amounts of interdiurnal temperature differences and pressure were calculated. Propagation of heat and cold waves, trends and frequencies of daily precipitation extremes were evaluated. The map “Zoning the territory of the Russian Federation by natural living conditions of the population” adapted for modern climate (2001-2010), illustrates the climate changes in the early 21st century. The modern warming of climate has led to a significant easing of discomfort in the territory of Russia. The steady decline of the absolutely unfavorable zone resulted from the expansion of less unfavorable areas is observed, especially in the Northern and Arctic regions. In the south the boundary of unfavorable territories shifts toward the north. It results in the expansion of the conditionally unfavorable area in West Siberia and in the south of East Siberia. In European Russia the favorable area expands and shifts far to the northern regions.

    Current education reform policies focus on raising academic achievement and ensuring that all students have access to high-quality education. Because the achievement gap is apparent even before children enter school, the authors believe that education reform must encompass the early childhood years. The current dialogue about universal preschool presents an opportunity to address the need for a national system for early care and education. The authors believe this system should provide quality child care and preschool experiences for all children and embrace a whole-child approach that nurtures not only cognitive development but physical and mental health and social-emotional behaviors that are also important to successful schooling. The School of the 21st Century provides an example of an effective early care and education system using the public schools. The authors' work with the School of the 21st Century shows that schools can provide high-quality, developmentally appropriate care and that these programs benefit later school performance. 2007 APA, all rights reserved

    The Hurst exponent of very long birth time series in Romania has been extracted from official daily records, i.e. over 97 years between 1905 and 2001 included. The series result from distinguishing between families located in urban (U) or rural (R) areas, and belonging (Ox) or not (NOx) to the orthodox religion. Four time series combining both criteria, (U,R) and (Ox, NOx), are also examined. A statistical information is given on these sub-populations measuring their XX-th century state as a snapshot. However, the main goal is to investigate whether the "daily" production of babies is purely noisy or is fluctuating according to some non trivial fractional Brownian motion, - in the four types of populations, characterized by either their habitat or their religious attitude, yet living within the same political regime. One of the goals was also to find whether combined criteria implied a different behavior. Moreover, we wish to observe whether some seasonal periodicity exists. The detrended fluctuation analysis technique is used for finding the fractal correlation dimension of such (9) signals. It has been first necessary, due to two periodic tendencies, to define the range regime in which the Hurst exponent is meaningfully defined. It results that the birth of babies in all cases is a very strongly persistent signal. It is found that the signal fractal correlation dimension is weaker (i) for NOx than for Ox, and (ii) or U with respect to R. Moreover, it is observed that the combination of U or R with NOx or OX enhances the UNOx, UOx, and ROx fluctuations, but smoothens the RNOx signal, thereby suggesting a stronger conditioning on religiosity rituals or rules.

    Diabetes mellitus, widely known to the ancients for polyuria and glycosuria, budded off diabetes insipidus (DI) about 200 years ago, based on the glucose-free polyuria that characterized a subset of patients. In the late 19th century, clinicians identified the posterior pituitary as the site of pathology, and pharmacologists found multiple bioactivities there. Early in the 20th century, the amelioration of the polyuria with extracts of the posterior pituitary inaugurated a new era in therapy and advanced the hypothesis that DI was due to a hormone deficiency. Decades later, a subset of patients with polyuria unresponsive to therapy were recognized, leading to the distinction between central DI and nephrogenic DI, an early example of a hormone-resistant condition. Recognition that the posterior pituitary had 2 hormones was followed by du Vigneaud's Nobel Prize winning isolation, sequencing, and chemical synthesis of oxytocin and vasopressin. The pure hormones accelerated the development of bioassays and immunoassays that confirmed the hormone deficiency in vasopressin-sensitive DI and abundant levels of hormone in patients with the nephrogenic disorder. With both forms of the disease, acquired and inborn defects were recognized. Emerging concepts of receptors and of genetic analysis led to the recognition of patients with mutations in the genes for 1) arginine vasopressin (AVP), 2) the AVP receptor 2 (AVPR2), and 3) the aquaporin 2 water channel (AQP2). We recount here the multiple skeins of clinical and laboratory research that intersected frequently over the centuries since the first recognition of DI.

    Aim of this study was to reconstruct the temporal and spatial phylodynamics of WNV-1a, the genotype to which the majority of European/Mediterranean viral strains belongs, by using sequences retrieved from public databases. WNV-1a isolates segregated into two major clades: the recent West Mediterranean sequences formed a single monophyletic group within clade A. Clade B included sequences from East Mediterranean and America. Phylogeographic analysis suggested that WNV-1a probably originated in sub-Saharan Africa in the early XXth century, and then spread northwards since the late 1970s, via two routes: one crossing Eastern Mediterranean and the other the Western Mediterranean countries. Our data suggest that the circulation of the virus in a given geographical area usually precedes the onset of the outbreak by one year or more, and underline the importance of the spatial-temporal phylodynamics reconstruction in clarifying the recent epidemiology and in setting up an efficient surveillance system for emerging/reemerging zoonosis.

    During the 19th century, rocket enthusiasts and inventors began to appear in almost every country. Some people thought these early rocket pioneers were geniuses, and others thought they were crazy. Claude Ruggieri, an Italian living in Paris, apparently rocketed small animals into space as early as 1806. The payloads were recovered by parachute. As depicted here by artist Larry Toschik, French authorities were not always impressed with rocket research. They halted Ruggieri's plans to launch a small boy using a rocket cluster.

In contrast to other commentaries (e.g., Kuehni & Schwarz, Color Ordered: A Survey of Color Order Systems from Antiquity to the Present, 2007, p. 36), we argue that the color space described by Grosseteste is explicitly three-dimensional. We seek the appropriate translation of Grosseteste’s key terms, making reference both to Grosseteste’s other works and the broader intellectual context of the 13th century, and to modern color spaces.

    2014-01-01

    The widespread influence exerted by the medical theories of Scottish doctor, John Brown, whose eponymously named Brunonianism radically simplified the ideas of his mentor, William Cullen, has not been generally recognised. However, the very simplicity of the Brunonian medical model played a key role in ensuring the dissemination of medical ideas about nervous irritability and the harmful effects of overstimulation in the literary culture of the nineteenth century and shaped early sociological thinking. This chapter suggests the centrality of these medical ideas, as mediated by Brunonianism, to the understanding of Romanticism in the nineteenth century, and argues that Brunonian ideas shaped nineteenth-century thinking about the effects of mass print culture in ways which continue to influence contemporary thinking about the effects of media.

    The mortality transition in Western Europe and the U.S. encompassed a much more complex set of conditions and experiences than earlier thought. Our research addresses the complex set of relationships among growing urban communities, family wealth, immigration and mortality in New England by examining individual-level, socio-demographic mortality correlates during the nineteenth-century mortality plateau and its early twentieth-century decline. In contrast to earlier theories that proposed a more uniform mortality transition, we offer an alternative hypothesis that focuses on the impact of family wealth and immigration on individual-level mortality during the early stages of the mortality transition in Northampton and Holyoke, Massachusetts.

  10. A visit to Biotopia: genre, genetics and gardening in the early twentieth century.

    PubMed

    Endersby, Jim

    2018-06-20

    The early decades of the twentieth century were marked by widespread optimism about biology and its ability to improve the world. A major catalyst for this enthusiasm was new theories about inheritance and evolution (particularly Hugo de Vries's mutation theory and Mendel's newly rediscovered ideas). In Britain and the USA particularly, an astonishingly diverse variety of writers (from elite scientists to journalists and writers of fiction) took up the task of interpreting these new biological ideas, using a wide range of genres to help their fellow citizens make sense of biology's promise. From these miscellaneous writings a new and distinctive kind of utopianism emerged - the biotopia. Biotopias offered the dream of a perfect, post-natural world, or the nightmare of violated nature (often in the same text), but above all they conveyed a sense that biology was - for the first time - offering humanity unprecedented control over life. Biotopias often visualized the world as a garden perfected for human use, but this vision was tinged with gendered violence, as it became clear that realizing it entailed dispossessing, or even killing, 'Mother Nature'. Biotopian themes are apparent in journalism, scientific reports and even textbooks, and these non-fiction sources shared many characteristics with intentionally prophetic or utopian fictions. Biotopian themes can be traced back and forth across the porous boundaries between popular and elite writing, showing how biology came to function as public culture. This analysis reveals not only how the historical significance of science is invariably determined outside the scientific world, but also that the ways in which biology was debated during this period continue to characterize today's debates over new biological breakthroughs.

  13. The emergence of medical specialization in the nineteenth century.

    PubMed

    Weisz, George

    2003-01-01

    This essay reexamines the nineteenth-century origins of medical specialization. It suggests that by the 1880s, specialization had become perceived as a necessity of medical science as a result of the realization of two preconditions: First, a new collective desire to expand medical knowledge prompted clinical researchers to specialize; only specialization, it was believed, permitted the rigorous observation of many cases. Second, administrative rationality suggested that one could best manage large populations through proper classification, gathering together individuals belonging to the same class and separating those belonging to different categories. Both of these conditions emerged first and most powerfully in early nineteenth-century Paris.

    The unique observing conditions allowed by total solar eclipses made them a highly desirable target of 19th and early 20th century astronomical expeditions, particularly after 1842. Due to the narrowness of the lunar shadow at the Earth's surface this usually implied traveling to faraway locations with all the subsequent inconveniences, in particular, high costs and complex logistics. A situation that improved as travel became faster, cheaper and more reliable. The possibility to observe an eclipse in one's own country implied no customs, no language barriers, usually shorter travelling distances and the likely support of local and central authorities. The eclipse proximity also provided a strong argument to pressure the government to support the eclipse observation. Sometimes the scientific elite would use such high profile events to rhetorically promote broader goals. In this paper we will analyse the motivation, goals, negotiating strategies and outcomes of the Portuguese eclipse expeditions made between 1860 and 1914. We will focus, in particular, on the observation of the solar eclipses of 22 December 1870 and 17 April 1912. The former allowed the start-up of astrophysical studies in the country while the movie obtained at the latter led Francisco da Costa Lobo to unexpectedly propose a polar flattening of the Moon.

    This study presents two independent reconstructions of precipitation from James Madison's Montpelier plantation at the end of the eighteenth century. The first is transcribed directly from meteorological diaries recorded by the Madison family for 17 years and reflects the scientific interests of James Madison and Thomas Jefferson. In his most active period as a scientist, Madison assisted Jefferson by observing the climate and fauna in Virginia to counter the contemporary scientific view that the humid, cold climate of the New World decreased the size and number of its species. The second reconstruction is generated using tree rings from a forest in the Montpelier plantation and connects Madison's era to the modern instrumental precipitation record. These trees provide a significant reconstruction of both early summer and prior fall precipitation. Comparison of the dendroclimatic and diary reconstructions suggests a delay in the seasonality of precipitation from Madison's era to the mid-twentieth century. Furthermore, the dendroclimatic reconstructions of early summer and prior fall precipitation appear to track this shift in seasonality.

  16. The riddle of sex: biological theories of sexual difference in the early twentieth-century.

    2011-01-01

    At the turn of the twentieth century, biologists such as Oscar Riddle, Thomas Hunt Morgan, Frank Lillie, and Richard Goldschmidt all puzzled over the question of sexual difference, the distinction between male and female. They all offered competing explanations for the biological cause of this difference, and engaged in a fierce debate over the primacy of their respective theories. Riddle propounded a metabolic theory of sex dating from the late-nineteenth century suggesting that metabolism lay at the heart of sexual difference. Thomas Hunt Morgan insisted on the priority of chromosomes, Frank Lillie emphasized the importance of hormones, while Richard Goldschmidt supported a mixed model involving both chromosomes and hormones. In this paper, I will illustrate how the older metabolic theory of sex was displaced when those who argued for the relatively newer theories of chromosomes and hormones gradually formed an alliance that accommodated each other and excluded the metabolic theory of sex. By doing so, proponents of chromosomes and hormones established their authority over the question of sexual difference as they laid the foundations for the new disciplines of genetics and endocrinology. Their debate raised urgent questions about what constituted sexual difference, and how scientists envisioned the plasticity and controllability of this difference. These theories also had immediate political and cultural consequences at the turn of the twentieth century, especially for the eugenic and feminist movements, both of which were heavily invested in knowledge of sex and its determination, ascertainment, and command.

    The article treats the Academy of the Linceans in the early nineteenth century, and more particularly during the Napoleonic domination of Rome in 1809-14. For the French regime, the Academy was instrumental to turning intellectuals into notables; pursuing the advancement of knowledge; stimulating industry; fostering secularization and orientating public opinion. But these goals did not always harmonize one with the other. Moreover, the local agenda was subordinated to strategic and ideological considerations pertaining to the organization of the Empire, relations with the Papacy, and internal politics. Hence, support to the Academy was subject to changes and contradictions. Within the Empire, the small local scientific elite found a place within international networks of science. Men of science increased their visibility and social standing, and greater symbolic and material resources were granted to the practice of science. The Academy, however, was left in the unclear status of a semi-public establishment, and it eventually imploded after the Restoration. The article analyses the Academy's scientific activity and its role in public life, focusing on material history as a key element to understand the ambiguous nature of Roman scientific institutions both under the papal government and the French regime.

  18. Making Space for Red Tide: Discolored Water and the Early Twentieth Century Bayscape of Japanese Pearl Cultivation.

    PubMed

    Ericson, Kjell

    2017-05-01

    "Red tide" has become a familiar shorthand for unusual changes in the color of ocean waters. It is intimately related both to blooms of creatures like dinoflagellates and to the devastating effects they pose to coastal fisheries. This essay tracks the early twentieth century emergence of discolored water as an aquacultural problem, known in Japan as akashio, and its trans-oceanic transformation into the terms and practices of "red tide" in the post-World War II United States. For Japan's "Pearl King" Mikimoto Kōkichi and his contacts in diverse marine scientific communities, the years-long cycle of guarding and cultivating a pearl oyster went together with the ascription of moral qualities to tiny creatures that posed a threat to farmed bayscapes of pearl monoculture. As akashio, discolored water went from curiosity to marine livestock pest, one that at times left dead pearl oysters in its wake. Red tide arose from the sustained study of the mechanisms by which changes in the biological and chemical composition of seawater might become deadly to exclusively-claimed shellfish along Japanese coastlines, but came to be seen as a way to understand aquatic manifestations of harm in other parts of the littoral world.

    2000-01-01

    A resurgence of interest in peroxide propulsion has occurred in the last years of the 21st Century. This interest is driven by the need for lower cost propulsion systems and the need for storable reusable propulsion systems to meet future space transportation system architectures. NASA and the Air Force are jointly developing two propulsion systems for flight demonstration early in the 21st Century. One system will be a development of Boeing's AR2-3 engine, which was successfully fielded in the 1960s. The other is a new pressure-fed design by Orbital Sciences Corporation for expendable mission requirements. Concurrently NASA and industry are pursuing the key peroxide technologies needed to design, fabricate, and test advanced peroxide engines to meet the mission needs beyond 2005. This paper will present a description of the AR2-3, report the status of its current test program, and describe its intended flight demonstration. This paper will then describe the Orbital 10K engine, the status of its test program, and describe its planned flight demonstration. Finally the paper will present a plan, or technology roadmap, for the development of an advanced peroxide engine for the 21st Century.

    2006-01-01

    Founded in the early 1900s, the 4-H Youth Development program can serve as a model for out-of-school programs of the twenty-first century. The 4-H pledge, repeated by its members--over 7 million, ranging in age from five to twenty--articulates its core values: "I pledge: My head to clearer thinking, My heart to greater loyalty, My hands to larger service, and My health to better living for my club, my community, my country, and my world." The 4-H Development movement was created to provide opportunities for rural children, to help them become constructive adults. Through an emphasis on "learning by doing," 4-H teaches children the habits of lifelong learning. Historically, 4-H has tapped into university-level advancements, extending such knowledge to youth and thereby giving them early access to scientific discoveries and technological progress. Members apply this learning in their communities through hands-on projects crossing a wide-range of pertinent topics. Research shows that 4-H members are more successful in school than other children and develop a wide range of skills essential in the twenty-first century. Thus, the author makes the case that the foundation of 4-H is exceptionally relevant in today's complex world, perhaps even more so than a century ago. 4-H is a leader in youth development, making it a natural model for twenty-first century after-school programs. Expanding on the 4-H pledge, the author outlines the principles a successful youth development program would have: an emphasis on leadership skills, a feeling of connection and belonging, a forum for exploring career opportunities, and a component of meaningful community service.

  3. Reconstructing Early Industrial Contributions to Legacy Trace Metal Contamination in Southwestern Pennsylvania.

    Early industrial trace metal loadings are poorly characterized but potentially substantial sources of trace metals to the landscape. The magnitude of legacy contamination in southwestern Pennsylvania, the cradle of North American fossil fuel industrialization, is reconstructed from trace metal concentrations in a sediment core with proxies including major and trace metal chemistry, bulk density, and magnetic susceptibility. Trace metal chemistry in this sediment record reflects 19th and 20th century land use and industry. In particular, early 19th century arsenic loadings to the lake are elevated from pesticides used by early European settlers at a lakeside tannery. Later, sediment barium concentrations rise, likely reflecting the onset of acidic mine drainage from coal operations. Twentieth century zinc, cadmium, and lead concentrations are dominated by emissions from the nearby, infamous Donora Zinc Works yet record both the opening of a nearby coal-fired power plant and amendments to the Clean Air Act. The impact of early industry is substantial and rivals more recent metal fluxes, resulting in a significant potential source of contaminated sediments. Thus, modern assessments of trace metal contamination cannot ignore early industrial inputs, as the potential remobilization of legacy contamination would impact ecosystem and human health.

  6. Figures and Institutions of the neurological sciences in Paris from 1800 to 1950. Part IV: Psychiatry and psychology.

    2012-05-01

    We present a short historical review on the major institutions and figures who contributed to make Paris a renowned centre of physiology and neurology during the XIXth and the first half of the XXth century. We purposely chose to focus on the period 1800-1950, as 1800 corresponds to the actual beginning of neurosciences, and as 1950 marks their exponential rise. Our presentation is divided into four chapters, matching the main disciplines that have progressed and contributed most to the knowledge we have of the brain sciences: anatomy, physiology, neurology, and psychiatry-psychology. The present article is the fourth of the four parts of this review, which deals with the chapter on psychiatry and psychology. When the French Revolution occurred, only a few institutions were taking care of the mentally ill. In the Paris area, these included Maison Royale de Charenton, Les Petites Maisons, and one of the departments of larger hospitals such as Hôtel-Dieu, the Salpêtrière Hospital and Bicêtre Hospital. One of the founders of psychiatry in Paris at that time and thereafter was Philippe Pinel (1745-1826) who was the first to distinguish insane/alienated patients from misfits, beggars, and other vagabonds. During the first half of the XIXth century, his student Jean-Étienne Esquirol (1772-1840) also played a major role with his treatise on mental diseases and the 1838 law and the creation of asylums in all parts of France. Alienists were in general caregivers and learned by themselves. In contrast, at the academic level, the emerging disciplines psychiatry and neurology were very close to each other in the second half of the XIXth century, the best example being Jules Baillarger (1809-1890). The actual development of psychiatry and psychology and the foundation of psychoanalysis later in the XIXth century and in the first half of the XXth century owed much to several European doctors and scientists, particularly those from British institutions and from German

    As temperatures increase, the onset and severity of droughts is likely to become more intense. Improved tools for understanding, monitoring and predicting droughts will be a key component of 21st century climate adaption. The best drought monitoring systems will bring together accurate precipitation estimates with skillful climate and weather forecasts. Such systems combine the predictive power inherent in the current land surface state with the predictive power inherent in low frequency ocean-atmosphere dynamics. To this end, researchers at the Climate Hazards Group (CHG), in collaboration with partners at the USGS and NASA, have developed i) a long (1981-present) quasi-global (50degS-50degN, 180degW-180degE) high resolution (0.05deg) homogenous precipitation data set designed specifically for drought monitoring, ii) tools for understanding and predicting East African boreal spring droughts, and iii) an integrated land surface modeling (LSM) system that combines rainfall observations and predictions to provide effective drought early warning. This talk briefly describes these three components. Component 1: CHIRPS The Climate Hazards group InfraRed Precipitation with Stations (CHIRPS), blends station data with geostationary satellite observations to provide global near real time daily, pentadal and monthly precipitation estimates. We describe the CHIRPS algorithm and compare CHIRPS and other estimates to validation data. The CHIRPS is shown to have high correlation, low systematic errors (bias) and low mean absolute errors. Component 2: Hybrid statistical-dynamic forecast strategies East African droughts have increased in frequency, but become more predictable as Indo- Pacific SST gradients and Walker circulation disruptions intensify. We describe hybrid statistical-dynamic forecast strategies that are far superior to the raw output of coupled forecast models. These forecasts can be translated into probabilities that can be used to generate bootstrapped ensembles

    PubMed

    2012-06-01

    Morphological assumptions concerning the form, structure and internal life of the brain and nervous system profoundly influenced contemporary physiological concepts about nerve actions throughout the 'long eighteenth century'. This article investigates some early theories of mind and metabolism. In a bottom-up fashion, it asks how eighteenth-century theories regarding the physiological actions of the body organs shaped the conceptions of the structure of the brain and nervous tissue themselves. These proposed that a healthy Nervennahrung (the German word for 'nerve nutrition', which might be rendered as brain food in modern English), not only guaranteed the integrity and stability of neuronal structures in the body, but also explained the complex texture of the brain and spinal cord in physiological terms. Eighteenth-century nerve theories already embodied a Leitmotiv of neurology and brain psychiatry from the later nineteenth century: 'Without phosphorus there is no thought!'

    Williamson, L

    1996-01-01

    This paper uses the archives of the St John's training institution for nurses and the Raynard Mission to determine the extent to which cultural images and specialised space defined and drove the nursing profession in nineteenth and early twentieth century London. Emphasis is placed upon image and rhetoric, both sacred and secular, and the way the two combined to define the 'ideal' Victorian woman and nursing in the nineteenth and early twentieth centuries, and the understanding and treatment of illness. Research to date suggests that through a process of rationalisation of biblical and socio-cultural rhetoric, a specialisation of space, symbolic and literal, abstract and real was created; this enabled women to work in a gendered enclave, the organisational structure and rhetoric of which paralleled that of nunneries or convents. And even as the 'secular' became dominant in medical attitudes and treatment, the 'sacred'aspect of nursing and the emphasis placed upon it as being a vocation remained strong.

    Although a number of studies indicate the regional heterogeneity of the glacier elevation and mass changes in high-mountain Asia in the early 21st century, little is known about these changes with high spatial detail for some of the regions. In this study we present respective glacier elevation and mass change estimates in the Indian state of Jammu and Kashmir (JK) for the period 2000-2012. Our estimates are based on the interferometric analysis of SRTM DEM and the bistatic TanDEM-X data. On an average the JK East (Karakoram) glaciers showed less negative elevation changes (- 0.19 ± 0.22 m yr-1) compared to the JK West (Himalaya) glaciers (- 0.50 ± 0.28 m yr-1). This agrees very well with previous studies that show a transition from larger changes in the western Himalaya to a steady-state situation in the Karakoram. We observe distinct elevation change patterns on a glacier scale that is most likely linked to debris insulation and the enhanced ice melting due to supraglacial lakes, ponds and ice cliffs. We also found 16 surge-type glaciers in the JK East which were not documented before. In total, 25 glaciers surged and 4 others appeared to be in a quiescent phase in the observation period. Our results also reveal that the glacier-averaged elevation change rates of surge-type and non surge-type glaciers in the JK East region are not significantly different.

    Physician scientists (researchers with either M.D. or M.D.-Ph.D. degrees) have the unique potential to combine clinical perspectives with scientific insight, and their participation in biomedical research has long been an important topic for policymakers and educators. Given the recent changes in the research environment, an update and extension of earlier studies of this population was needed. Our findings show that physician scientists are less likely to take a major role in biomedical research than they were in the past. The number of physician scientists receiving postdoctoral research training and career development awards is at an all-time low. Physician scientists today, on average, receive their first major research award (R01 equivalent) at a later age than in the 1980s. The number of first-time R01-equivalent awards to physicians is at the same level as it was 30 yr ago, but physicians now represent a smaller percentage of the grant recipients. The long-term decline in the number of physicians entering research careers was temporarily halted during the period of substantial U.S. National Institutes of Health (NIH) budget growth (1998–2003). These gains are lost, however, in the subsequent years when NIH budgets failed to keep pace with rising costs.— Garrison, H. H., Deschamps, A. M.

    2013-09-01

    This essay explores various ways in which bibliographies have exhibited "sociality." Bibliographies are both products of the social contexts that have created them and engines of social interaction in scholarly communities. By tracing the history of the Isis Bibliography, the longest-running and most comprehensive bibliography in its field, this essay explains how different Isis classification systems have been tied to major twentieth-century cataloging efforts. By looking at classification, the essay also attends to the ways in which aspects of the Isis Bibliography in different decades have reflected social mores of their period. Finally, it demonstrates how critical the Isis Bibliography was in the formation of the discipline of history of science and goes on to discuss how that disciplinary connection is evolving in the twenty-first century. By thinking of the bibliography as a network of scholars, not just scholarly works, the essay asks us to reflect on the nature and purpose of bibliography in the digital age.

    The aim of this paper is to show how the Greek men of science negotiated a role for their enterprise within the Greek public sphere, from the institution of the modern Greek state in the early 1830s to the first decades of the twentieth century. By focusing on instances where they appeared in public in their official capacity as scientific experts, I describe the rhetorical schemata and the narrative strategies with which Greek science experts engaged the discourses prevalent in nineteenth- and early twentieth-century Greece. In the end, my goal is to show how they were neither zealots of modernization nor neutral actors struggling in isolated wastelands. Rather, they appear as energetic agents who used scientific expertise, national ideals and their privileged cultural positions to construct a rhetoric that would further all three. They engaged eagerly and consistently with emerging political views, scientific subjects and cultural and political events, without presenting themselves, or being seen, as doing anything qualitatively different from their peers abroad. Greek scientists cross-contextualized the scientific enterprise, situating it in the space in which they were active.

    2011-01-01

    The nineteenth-century Chinese population in Australia was made up mostly of men, drawing many commentators to the conclusion these men faced an absence of family life, resulting in prostitution, gambling, opium use and other so-called vices. Recent research has, however, expanded and complicated our knowledge of Chinese families in New South Wales and Victoria, particularly concerning the extent to which Chinese men and white Australian women formed intimate relationships. This article traces the origins of the misconceptions about Chinese families in nineteenth-century Australia, and considers how new directions in scholarship over the past decade are providing methods for enlarging our knowledge. It argues that instead of being oddities or exceptions, Chinese-European families were integral to the story of Australia's early Chinese communities.

    The aim of this study was to assess the impact of social and occupational status on the BMI of the gentry and peasantry in the Kingdom of Poland at the turn of 19th and early 20th centuries. Use was made of data on the height and weight of 304 men, including 200 peasants and 104 gentlemen, and 275 women, including 200 from the peasantry and 75 from the gentry. Gentlemen were characterized by a greater body height than peasants (169.40 cm and 166.96 cm, respectively), a greater body weight (67.09 kg and 60.99 kg, respectively) and a higher BMI (23.33 kg/m2 and 21.83 kg/m2, respectively). Landowners and intelligentsia had a greater BMI than peasants (23.12 kg/m2 and 24.20 kg/m2 vs 21.83 kg/m2, respectively). In the case of women, there were no statistically significant differences in mean height, weight and BMI by their social position, and in BMI by occupational status. Underweight occurred less frequently in the gentry and more frequently in the peasantry (0.97% and 2.04%, respectively). Overweight was five times more common in gentlemen than in peasants (26.21% and 5.10%, respectively). Differences in the BMI of gentlefolk and peasants resulted from differences in diet and lifestyle related to socioeconomic status.

    A historical and metallurgical characterization of a "falchion" sword manufactured in Caino (Brescia, northern Italy) and dating from the early 17th century was performed to understand the manufacture methods of a Renaissance sword. At first, a set of size measurements was carried out to look for the existence of constant and/or recurring macroscopic sizes, which would indicate a standardized production, or of any type of proportionality between different parts of a sword, which would prove an intentional design activity. Light optical microscopy, scanning electron microscopy, energy-dispersive x-ray spectroscopy, quantometer analyses, and Vickers microhardness tests were then employed to analyze the microstructure and obtain the mechanical properties. All the metallurgical work is supported by an accurate study on the chemical composition of both metal-matrix and nonmetallic inclusions, which allowed for rebuilding and evaluating the efficiency of the whole production process.

    We have relocated seismic events registered within the Barents and Kara sea region from early twentieth century to 1989 with a view to creating a relocated catalog. For the relocation, we collected all available seismic bulletins from the global network using data from the ISC Bulletin (International Seismological Centre), ISC-GEM project (International Seismological Centre-Global Earthquake Model), EuroSeismos project, and by Soviet seismic stations from Geophysical Survey of the Russian Academy of Sciences. The location was performed by applying a modified method of generalized beamforming. We have considered several travel time models and selected one with the best location accuracy for ground truth events. Verification of the modified method and selection of the travel time model were performed using data on four nuclear explosions that occurred in the area of the Novaya Zemlya Archipelago and in the north of the European part of Russia. The modified method and the Barents travel time model provide sufficient accuracy for event location in the region. The relocation procedure was applied to 31 of 36 seismic events registered within the Barents and Kara sea region.

    1988-05-01

    Although other forms of allergic disease were described in antiquity, hay fever is surprisingly modern. Very rare descriptions can be traced back to Islamic texts of the 9th century and European texts of the 16th century. It was only in the early 19th century that the disease was carefully described and at that time was regarded as most unusual. By the end of the 19th century it had become commonplace in both Europe and North America. This paper attempts to chart the growth of hay fever through the medical literature of the 19th century. It is hoped that an understanding of the increase in prevalence between 1820 and 1900 may provide an insight for modern researchers and give some clues into possible reasons for the epidemic nature of the disease today.

    The pages of popular magazines such as Sky and Telescope and Astronomy are filled with advertisements for telescopes and other equipment. However, during the past century astronomical imagery has been widely used to promote distinctly non-astronomical products and services. One of the earliest and most famous examples is the 1893 Chicago newspaper advertisement for Kirk's Soap, which was inspired by the opening of the Yerkes Observatory. A survey of popular magazines published in America during the first half of the twentieth century suggests that these advertisements fall into four categories: 1) Astronomy is universally regarded as an exact and precise science. Manufacturers of mechanical devices may employ images of telescopes or astronomers at work to suggest that their products meet these same standards of quality. This was primarily the case with makers of automobiles and automotive products, although the Longines Watch Company ran an extensive series of ads featuring observatories. 2) The heavens induce a sense of wonder in most people, and advertisers may locate their products in an a celestial setting to give them an otherworldly flavor. 3) Astronomical observatories themselves are viewed as exotic settings, and have provided backgrounds for automotive and travel ads. They may also appear in advertisements for products used in their construction. 4) Finally, newsworthy astronomical events will inspire advertisers to associate their products with that event, in order to capitalize upon the publicity. This was particularly true in the case of the 1910 passage of Halley's Comet and the 1948 opening of the 200-inch Hale telescope at Mt. Palomar. Examples of magazine advertisements from each category are presented for comparison. This work was supported by a faculty development grant from Valdosta State University.

  5. Veterinary entomology, colonial science and the challenge of tick-borne diseases in South Africa during the late nineteenth and early twentieth centuries.

    Brown, K

    2008-12-01

    This article provides an historical overview of developments in veterinary entomology during the late nineteenth and early twentieth centuries. During that period state employed entomologists and veterinary scientists discovered that ticks were responsible for transmitting a number of livestock diseases in South Africa. Diseases such as heartwater, redwater and gallsickness were endemic to the country. They had a detrimental effect on pastoral output, which was a mainstay of the national economy. Then in 1902 the decimating cattle disease East Coast fever arrived making the search for cures or preventatives all the more urgent. Vaccine technologies against tick-borne diseases remained elusive overall and on the basis of scientific knowledge, the South African state recommended regularly dipping animals in chemical solutions to destroy the ticks. Dipping along with quarantines and culls resulted in the eradication of East Coast fever from South Africa in the early 1950s. However, from the 1930s some ticks evolved a resistance to the chemical dips meaning that diseases like redwater were unlikely to be eliminated by that means. Scientists toiled to improve upon existing dipping technologies and also carried out ecological surveys to enhance their ability to predict outbreaks. Over the longer term dipping was not a panacea and ticks continue to present a major challenge to pastoral farming.

    In the presentation an overview of weather events, documented in contemporary written sources - available both in private and institutional evidence -, is provided: geographically the study covers the Hungarian kingdom (occasionally also with sources from the medieval Croatian kingdoms) that included most parts of the Carpathian Basin. Even if the temporal coverage extends the high and late medieval period between 1000 to 1500, most of the data comes from the late medieval times, with special emphasis on the 15th century. Most of the information is available regarding cold spells (e.g. early and late frosts), but especially cold winter periods. Nevertheless, contemporary documentary evidence - mainly legal documentation (charters), official and private correspondence, partly narratives and town accounts - also consists of evidence concerning other, weather-related extreme events such as (thunder)storms, floods and droughts. Apart from the discussion of the availability and type of these events, based on the relative frequency of occurrence we can define periods when a higher frequency and magnitude of weather-related events were reported that is mainly not dependent on changing source densities. These detectable periods (e.g. the early and mid-14th, early and late 15th centuries) are also a further, separate topic of discussion in the presentation.

    At the beginning of the XXth century, Wegener proposed a theory – that of the roaming drift of the continents – unifying the rival theories of the Europeans and the Americans. As the work of a non-specialist who didn’t trouble himself with specific details, it raised numerous criticisms from specialists in various disciplines though others welcomed and supported it. Some even understood that despite its flaws, it started a new research program. Paradoxically, as regards its simplicity, nonspecialists – engineers, popularizers, secondary school teachers and even believers in para-sciences – gave it a favorable reception. Being amateurs, they continued to endorse it when specialists abandoned it.

    During the last two decades, the Arctic was put into the scientific focus as one of the most impacted regions worldwide concerning anthropogenic global warming. However, the warming between 1920 and 1940 proofs the importance of internal variability on yearly and decadal scale. Therefore, it is important to further investigate the role of external and internal forcings on the Arctic climate attribute process and causes leading to changes in the Arctic climate regime (Serreze & Barry 2009). Although much research effort was spent to understand the links and influences of and on the Arctic climate, there is still a need for further insights concerning this topic. Especially the results and discussion about anthropogenic global warming and Arctic amplification put the Arctic into the public and academic focus (Serreze & Barry 2011). However, the early 20th century Arctic warming, although discovered immediately, was scientifically forgotten until recently (Delworth & Knutson 2000, Bengtsson et al 2004, Grant et al 2009, Bekryaev et al 2010). The comparison of this earlier Arctic warming and the recent warming period grants a chance to deepen knowledge about the drivers of Arctic climate and can be used to evaluate the anthropogenic impact. The authors use the Twentieth Century Reanalysis (20CR) dataset and a nudged, reanalysis-driven Aerosol Global Circulation Model (A-GCM) to investigate the impact of atmospheric energy and aerosol fluxes into the Arctic during the 20th century. The 20CR dataset covers the period of 1871 - 2010 with a temporal resolution of 6hr and a spatial resolution of 2° x 2°. For the first time, this dataset (and ist 56 ensemble member) is used to compute the atmospheric energy flux, consisting of sensble heat, latent heat, potential energy and kinetic energy. The values are integrated around 70° N and between 1000 - 100 hPa. Aerosol fluxes for the same domain but for the years 1957 - 2000 are calculated based on the A-GCM nudged to the ECMWF

    Benjamin Banneker is considered to be the first African-American man of science (1731-1806), a contempory of George Washington and Thomas Jefferson. He was a self taught clock maker, mathematician, and astronomer. He owned land in Baltimore County near Ellicott City, Maryland where he farmed tobacco. He is especially known for his work on the Boundary Survey of our new Capital. Surveyors place boundary stones along the boundary of the nascent Capital. Banneker was part of the team who measured the latitutde and longitude for each stone. Using 18th century surveying techniques Banneker became part of the early history of Washington DC. He also published popular almanacs.

    2012-04-01

    An oft-cited belief that, until recently, simulators used in education of health care professionals were simple models is wrong. Hundreds of years ago and, in one instance, thousands of years ago, intricate models were used to help teach anatomy and physiology and in training in obstetrics and many surgical disciplines. Simulators were used to learn skills before performing them on patients and in high-stakes assessment.The newest technologies were often used in simulators to improve fidelity. In the 18th century, obstetric simulators could leak amniotic fluid, and blood were used to train midwives and obstetricians to recognize and manage complications of childbirth. Italy was the major source of simulators early in the 18th century, but in the 19th century, dominance in clinical simulation moved to France, Britain, and then Germany. In comparison, much of the 20th century was a "dark age" for simulation.

    Detection and attribution of human influence on sea level rise are important topics that have not yet been explored in depth. We question whether the sea level changes (SLC) over the past century were natural in origin. SLC exhibit power law long-term correlations. By estimating Hurst exponent through Detrended Fluctuation Analysis and by applying statistics of Lennartz and Bunde, we search the lower bounds of statistically significant external sea level trends in longest tidal records worldwide. We provide statistical evidences that the observed SLC, at global and regional scales, is beyond its natural internal variability. The minimum anthropogenic sea level trend (MASLT) contributes to the observed sea level rise more than 50% in New York, Baltimore, San Diego, Marseille, and Mumbai. A MASLT is about 1 mm/yr in global sea level reconstructions that is more than half of the total observed sea level trend during the XXth century.

    From the early 1960s, the US National Library of Medicine (NLM) has been a leader in applying computer technology to accomplish traditional bibliographic and reference functions. medline, in the early 1970s, was the first large-scale online medical bibliographic reference system. That role has been altered by today's Web environment, which has increased the number and extent of NLM services and the audience for them. The NLM has formally declared that it will seek to serve the general public after over a century of serving the library and medical communities exclusively. In the last several years, many new services have been introduced to fulfil this mandate, including medlineplus and ClinicalTrials.gov. Also a part of the NLM's vision for the 21st century is the need to ensure that the proliferating forms of electronic health information-bibliographic, full text, graphic, audiovisual-are captured and preserved for posterity. A national library such as the NLM has as much an archival responsibility for this electronic information as for centuries-old printed and manuscript historical treasures.

    "Sumali," as an imported cobalt ore from overseas, was a sort of precious and valuable pigment used for imperial kilns only, which produces characteristic "iron spot" to blue-and-white porcelain in early Ming Dynasty (A.D. 14th-15th century). Although there were some old studies on it, the morphology and formation of iron spot has not been fully investigated and understood. Therefore, five selected samples with typical spot from Jingdezhen imperial kiln in Ming Yongle periods (A.D. 1403-1424) were analyzed by various microscopic analysis including 3D digital microscope, SEM-EDS and EPMA. According to SEM images, samples can be divided into three groups: un-reflected "iron spot" without crystals, un-reflected "iron spot" with crystals and reflected "iron spot" with crystals. Furthermore, 3D micro-images revealed that "iron spots" separate out dendritic or snow-shaped crystals of iron only on and parallel to the surface of glaze for which "iron spot" show strong metallic luster. Combining with microscopic observation and microanalysis on crystallization and non-crystallization areas, it indicates that firing oxygen concentration is the ultimate causation of forming reflective iron spot which has a shallower distribution below the surface and limits crystals growing down. More details about characters of "iron spot" used "Sumali" were found and provided new clues to coloration, formation mechanism and porcelain producing technology of imperial kiln from 14th to 15th centuries of China. © 2016 Wiley Periodicals, Inc.

  16. The Lazy Reader: Labor, Books, and Disease in Nineteenth-Century Germany.

    PubMed

    Aselmeyer, Norman

    Looking at nineteenth-century Germany, this article investigates the origin of the idea that fiction causes disease, among both the bourgeoisie and the working class. I argue that the socially constructed notions of reading addiction, which were consistent with medical concepts at that time, touched the bourgeois virtues of industriousness and health. However, little has been written about the transfer of the bourgeois attitudes towards reading to the German working class. The study of workers' autobiographies shows that social circumstances and the emulation of bourgeois values and attitudes resulted in appropriating the concept of lazy readers in the working class. The paper follows the paths from the early nineteenth century accusation of readers to the working class's perception of novels causing disease around 1900.

    At the beginning of the Renaissance magical, witchcraft and demonological medicine still played a large role in the poor healing ability of chronic leg ulcers. This included the general administration of magical potions and topical application. An example of the manipulation of the whole body by the devil was the Abracadabra text from Johann Christoph Bitterkraut in the year 1677. The use of bewitched ointments was particularly propagated by Paracelsus in 1622; however, even as early as the beginning of the seventeenth century, the invocation of supernatural powers was slowly diminishing until at the beginning of the nineteenth century the medical schools on chronic leg ulcers could be cultivated at the universities and by specialized wound healers.

    We present a new analysis of Robert Grosseteste’s account of color in his treatise De iride, On the Rainbow, dating from the early 13th century. The work explores color within the three-dimensional framework set out in Grosseteste’s De colore (see Smithson et al, 2012, A three-dimensional color space from the 13th century.” Journal of the Optical Society of America (A), 29 (2), A346-A352), but now links the axes of variation to observable properties of rainbows. We combine a modern understanding of the physics of rainbows and of human color perception to resolve the linguistic ambiguities of the medieval text and to interpret Grosseteste’s key terms.

    Following the Mongolian invasion of the Middle East in the thirteenth century, a regional power called the Ilkhanid emerged and was ruled by the heirs of Temujin from Mongolia. Embracing present-day Iran, Iraq, Afghanistan, Azerbaijan, areas of Russia, Turkey, and Pakistan, and nearby Middle Eastern territories, the Ilkhanid state patronized medicine and various other professions. Centered in Tabriz (Tauris), a city in the northwest of present-day Iran, was a non-profit-making educational and medical complex founded by Grand Minister Rashid al-Din Fazlollah Hamadani. This paper reviews the literature regarding the rise and fall of the thirteenth century university and the Rabi Rashidi, emphasizing the structure of its medical school. The background training of Rashid al-Din and his keen interest in science turned this complex, Rabi Rashidi (literally meaning the Rashidi Quarters), into a cosmopolitan university that freely trained medical scholars nationally and internationally. The possibility that Rashid al-Din was inspired by university developments in Europe is discussed.

    The development of organic and physical chemistry as specialist fields, during the middle and end of the 19th century respectively, left inorganic behind as a decidedly less highly regarded subfield of chemistry. Despite Alfred Werner's groundbreaking studies of coordination chemistry in the early 20th century, that inferior status remained in place - particularly in the US - until the 1950s, when the beginnings of a resurgence that eventually restored its parity with the other subfields can be clearly observed. This paper explores the extent to which Werner's heritage - both direct, in the form of academic descendants, and indirect - contributed to those advances.

    In a bold 2004 paper, Craig Venter and Daniel Cohen* claimed that whereas the 20th century had been the Century of Physics (Special and General Relativity, Quantum Mechanics, Big Bang Cosmology, Dark Matter and Dark Energy, the Standard Model of Particle Physics…) the 21st century would be the century of biology. They outlined the fantastic potential of genomic research to define the current century. Wondrous as these predictions were, and as rapidly as they have played out and over-delivered during this past decade, these predictions were too parochial. This century will permit us the first opportunities to study biology beyond Earth; biology as we don’t yet know it, and biology that we have exported off the surface of our planet.The technologies needed for discovering biology beyond Earth are different depending on whether you are searching for microbes or mathematicians, and depending on whether you are searching in-situ or remotely. In many cases the necessary technologies do not yet exist, but like genomics, they will probably develop more rapidly, and in more ways, than anyone of us can now imagine. The developing toolkit of the astronomers (stellar, planetary, and exoplanetary) will be shaped and improved as a result of this focus for at least the rest of this century.* New Perspectives Quarterly, Vol 21, pp. 73-77, 2004

    In 1790, Marie Rozette, a freedwoman of Indian origin on Mauritius, executed a series of notarial acts which revealed that she possessed a small fortune in cash assets as well as slaves and substantial landed property in one of the island’s rural districts. The life of this former slave between 1776, when she first appears in the archival record, and her death in 1804 provides a vantage point from which to gain a subaltern perspective on aspects of Mascarene social and economic history, as well as developments in the wider Indian Ocean world during the late eighteenth and early nineteenth centuries. Marie Rozette’s life history challenges the notion that free persons of color in Mauritius were little more than an “unappropriated” people, and invites us to consider how supposedly marginalized individuals were able to cross various socio-economic and cultural boundaries. More specifically, her life affords an opportunity to consider the ways in which class, ethnicity, and gender, as well as race, interacted to create a distinctive Creole society in Mauritius, the nature and dynamics of which bear directly on our knowledge and understanding of the free colored experience elsewhere in the European colonial slave plantation world.

This study examines how poverty and gender influenced incarceration practices, treatment and release in sixteenth-century Paris. A study of the archives of the ecclesiastical gaol at Saint-Germain-des-Prés from 1537 to 1579 suggests that both poverty and gender affected the crimes for which women and men were imprisoned, the length of time they remained in detention and the reasons for their release.

  6. Suppressing Synonymy with a Homonym: The Emergence of the Nomenclatural Type Concept in Nineteenth Century Natural History.

    PubMed

    Witteveen, Joeri

    2016-02-01

    'Type' in biology is a polysemous term. In a landmark article, Paul Farber (Journal of the History of Biology 9(1): 93-119, 1976) argued that this deceptively plain term had acquired three different meanings in early nineteenth century natural history alone. 'Type' was used in relation to three distinct type concepts, each of them associated with a different set of practices. Important as Farber's analysis has been for the historiography of natural history, his account conceals an important dimension of early nineteenth century 'type talk.' Farber's taxonomy of type concepts passes over the fact that certain uses of 'type' began to take on a new meaning in this period. At the closing of the eighteenth century, terms like 'type specimen,' 'type species,' and 'type genus' were universally recognized as referring to typical, model members of their encompassing taxa. But in the course of the nineteenth century, the same terms were co-opted for a different purpose. As part of an effort to drive out nomenclatural synonymy - the confusing state of a taxon being known to different people by different names - these terms started to signify the fixed and potentially atypical name-bearing elements of taxa. A new type concept was born: the nomenclatural type. In this article, I retrace this perplexing nineteenth century shift in meaning of 'type.' I uncover the nomenclatural disorder that the new nomenclatural type concept dissolved, and expose the conceptual confusion it left in its tracks. What emerges is an account of how synonymy was suppressed through the coinage of a homonym.

    The National Observatory of Brazil was created in 1827. It was initially focused on the practical teaching of Astronomy to the students of military and naval academies. Since the mid-nineteenth century to the early twentieth century it was installed over the ruins of a Jesuit church located in the center of Rio de Janeiro, capital of the Brazilian Empire.Due to the constant complaints of its successive directors, the search for a new site to house the Observatory began in 1911. The new headquarters of the institution were located on the hill of São Januário, a little further but still around the city center of Rio de Janeiro. Its inauguration took place in 1921.The main building of the new Observatory was based on one of the Brazilian pavilions of the Turin Exhibition of 1911, and its architecture can be characterized as eclectic. The pavilions intended to house the many telescopes were scattered in a large wooded area. Since 1985 all these facilities are protected by the Federal government, as a consequence of the same initiative that gave birth to the Museum of Astronomy and Related Sciences, which has the custody also of the Observatory’s former instruments, furniture, and documents.Although built in the early twentieth century the National Observatory new facilities reveal astronomical practices typical of the previous century. One of its most important activities was the determination of the legal time, a task that justifies its location in the urban environment. It was also responsible for the organization of expeditions destined to determine the geographical positions of railroads and the borders of Brazil. For this reason, the Museum of Astronomy has currently more than 3,000 portable instruments. Moreover, these instruments belong to the domain of Astronomy, but also to Geodesy, Meteorology, Electricity. Due to the creation of the Museum of Astronomy, this rich collection is now open to public visitation, and has become the object of scholarly

  11. The early history of the synapse: from Plato to Sherrington.

    PubMed

    Bennett, M R

    1999-09-15

    One hundred years ago, in 1897, Sherrington adopted the name synapse. However, the concept of the synapse emerged from considerations of how muscles are contracted and so locomotion affected over a period of 2400 years, from the time of Plato and Aristotle in the 4th century BC to the early part of the 20th century. This early history is considered in the present review. In terms of duration of influence, the early history was dominated by Aristotle's concept of vital pneuma. This was derived from the ether which filled all space, taken in by the lungs, transformed to vital pneuma in the heart, and then conducted in the blood stream to be transmitted to muscles. The vital pneuma then initiated the final phase of the muscle's psyche, that is, its contraction leading to locomotion. Aristotle's ideas had to be modified with the discovery by Galen and his students in the 2nd and 3rd centuries AD that nerves arising from the brain and spinal cord are necessary for the initiation of muscle contraction. They modified the Aristotlean account so that the vital pneuma delivered by blood vessels to the brain was converted there to psychic pneuma, from whence it was conducted along nerves to be transmitted to muscle, so allowing the muscle to contract. There matters rested for about 1300 years until Descartes. Descartes rejected the idea of organs and muscles possessing a psyche with a final cause that was released by the conduction and transmission of psychic pneuma in nerves, emphasising that mechanical explanations must be sought when determining the function of an organ or muscle. He argued in his corpuscular theory that fine particles derived from the blood in the brain, which he gave the unfortunate name of animal spirits, were conducted and transmitted along nerves to enter muscle during transmission, so leading to the increase in width of the muscle fibres, their shortening and contraction. This description was elaborated on in great detail by Descartes, and by his

    The history between cetaceans and humans is documented throughout time not only in reports, descriptions, and tales but also in legal documents, laws and regulations, and tithes. This wealth of information comes from the easy spotting and identification of individuals due to their large size, surface breathing, and conspicuous above water behaviour.

    The history between cetaceans and humans is documented throughout time not only in reports, descriptions, and tales but also in legal documents, laws and regulations, and tithes. This wealth of information comes from the easy spotting and identification of individuals due to their large size, surface breathing, and conspicuous above water behaviour.

    As surgery grew to become a respected medical profession in the eighteenth century, medical ethics emerged as a response to the growing need to protect patients and maintain the public's trust in physicians. The early influences of John Gregory and Thomas Percival were instrumental in the formulation of patient-centered medical ethics. In the late nineteenth century, the modern surgical advances of anesthesia and antisepsis created the need for a discipline of ethics specific to surgery in order to confront new and evolving ethical issues. One of the founding initiatives of the American College of Surgeons in 1913 was to eliminate unethical practices such as fee-splitting and itinerant surgery. As surgery continued to advance in the era of solid organ transplantation and minimally invasive surgery in the latter half of the twentieth century, surgical innovation and conflict of interest have emerged as important ethical issues moving forward into the twenty-first century. Surgical ethics has evolved into a distinct branch of medical ethics, and the core of surgical ethics is the surgeon-patient relationship and the surgeon's responsibility to advance and protect the well-being of the patient.

  16. Effects of Irrigation on Global Climate During the 20th Century

    Various studies have documented the effects of modern ]day irrigation on regional and global climate, but none, to date, have considered the time ]varying impact of steadily increasing irrigation rates on climate during the 20th century. We investigate the impacts of observed irrigation changes over this century with two ensemble simulations using an atmosphere general circulation model. Both ensembles are forced with transient climate forcings and observed sea surface temperatures from 1902 to 2000; one ensemble includes irrigation specified by a time ]varying data set of irrigation water withdrawals. Early in the century, irrigation is primarily localized over southern and eastern Asia, leading to significant cooling in boreal summer (June.August) over these regions. This cooling spreads and intensifies by century fs end, following the rapid expansion of irrigation over North America, Europe, and Asia. Irrigation also leads to boreal winter (December.February) warming over parts of North America and Asia in the latter part of the century, due to enhanced downward longwave fluxes from increased near ]surface humidity. Precipitation increases occur primarily downwind of the major irrigation areas, although precipitation in parts of India decreases due to a weaker summer monsoon. Irrigation begins to significantly reduce temperatures and temperature trends during boreal summer over the Northern Hemisphere midlatitudes and tropics beginning around 1950; significant increases in precipitation occur in these same latitude bands. These trends reveal the varying importance of irrigation ]climate interactions and suggest that future climate studies should account for irrigation, especially in regions with unsustainable irrigation resources.

    The C. T. Williamson spoon with manufactured products from a pharmaceutical company engraved on the bowl of the spoon is one of the earliest examples of a manufacturer marketing products via a drug delivery device. The Burroughs, Wellcome and Company, a British corporation using initially an American patented, and later a British patented, Williamson corkscrew spoon marketed British manufactured medicinal products in the U.S. and England to physicians and pharmacists in the late nineteenth and early twentieth century. Other corkscrew spoons were manufactured in this era without product specific notations contained on the spoons. 40 These corkscrew spoons, such as the Williamson and Noe patented apparatuses, helped patients in more easily consuming liquid medications. They also were items potentially favored by physicians and pharmacists for patient's pro- vided liquid medications. Finally, they allowed patients to open corked containers, consume liquid dosage amounts, and hopefully more appropriately comply with necessary regimens in the late nineteenth and early twentieth century. Not surprisingly, Burroughs, Wellcome and Company used the Williamson spoon to successfully market company products to physicians, pharmacists, and patients on several continents.

    2017-01-01

    In sediment cores spanning ~500 years of history in the Gulf of Trieste, down-core changes in molluscan community structure are characterized by marked shifts in species and functional composition. Between the 16th and 19th century, a strong heavy metal contamination of the sediments, most notably by Hg, together with the effects of natural climatic oscillations (increased sedimentation and organic enrichment) drive community changes. Since the early 20th century up to 2013, the combined impacts of cultural eutrophication, frequent hypoxic events and intensifying bottom trawling replace heavy metal contamination and climatic factors as the main drivers. The pollution-tolerant and opportunistic bivalve Corbula gibba and the scavenging gastropod Nassarius pygmaeus significantly increase in abundance during the 20th century, while species more sensitive to disturbances and hypoxia such as Turritella communis and Kurtiella bidentata become rare or absent. An infaunal life habit and scavenging emerge as the dominant life strategies during the late 20th century. Down-core shifts in the proportional abundances of molluscan species and functional groups represent a sensitive proxy for past ecological changes and reveal a century-long anthropogenic impact as the main driver behind these processes in the northern Adriatic Sea, offering also a unique perspective for other shallow marine ecosystems worldwide.

Father Raimbault, "doctor" and chaplain of the lepers in the middle of the twentieth century, is still honored today. The improvement in living standards and the use of sulfones finally resulted in the control of leprosy. Nonetheless, from 2005 to 2011, an average of three new cases per year were detected among a population of 800,000 inhabitants.

    Seismicity rates have increased sharply since 2009 in the central and eastern United States, with especially high rates of activity in the state of Oklahoma. Growing evidence indicates that many of these events are induced, primarily by injection of wastewater in deep disposal wells. The upsurge in activity has raised two questions: What is the background rate of tectonic earthquakes in Oklahoma? How much has the rate varied throughout historical and early instrumental times? In this article, we show that (1) seismicity rates since 2009 surpass previously observed rates throughout the twentieth century; (2) several lines of evidence suggest that most of the significant earthquakes in Oklahoma during the twentieth century were likely induced by oil production activities, as they exhibit statistically significant temporal and spatial correspondence with disposal wells, and intensity measurements for the 1952 El Reno earthquake and possibly the 1956 Tulsa County earthquake follow the pattern observed in other induced earthquakes; and (3) there is evidence for a low level of tectonic seismicity in southeastern Oklahoma associated with the Ouachita structural belt. The 22 October 1882 Choctaw Nation earthquake, for which we estimate Mw 4.8, occurred in this zone.

    2014-03-01

    This article is a review of the foundation (in 1838) and later developments of the Helsinki (Finland) magnetic and meteorological observatory, today the Finnish Meteorological Institute (FMI). The main focus of the study is in the early history of the FMI up to the beginning of the 20th century. The first director of the observatory was Physics Professor Johan Jakob Nervander (1805-1848). He was a famous person of the Finnish scientific, academic and cultural community in the early decades of the 19th century. Finland was an autonomously part of the Russian Empire from 1809 to 1917, but the observatory remained organizationally under the University of Helsinki, independent of Russian scientific institutions, and funded by the Finnish Government. Throughout the late-19th century the Meteorological Institute was responsible of nationwide meteorological, hydrological and marine observations and research. The observatory was transferred to the Finnish Society of Sciences and Letters under the name the Central Meteorological Institute in 1881. The focus of the work carried out in the Institute was changed gradually towards meteorology. Magnetic measurements were still continued but in a lower level of importance. The culmination of Finnish geophysical achievements in the 19th century was the participation to the International Polar Year programme in 1882-1883 by setting up a full-scale meteorological and magnetic observatory in Sodankylä, Lapland.

    Few studies have considered the role of immigration in the rise of gentrification in the late twentieth century. Analysis of U.S. Census and American Community Survey data over 24 years and field surveys of gentrification in low-income neighborhoods across 23 U.S. cities reveal that most gentrifying neighborhoods were “global” in the 1970s or became so over time. An early presence of Asians was positively associated with gentrification; and an early presence of Hispanics was positively associated with gentrification in neighborhoods with substantial shares of blacks and negatively associated with gentrification in cities with high Hispanic growth, where ethnic enclaves were more likely to form. Low-income, predominantly black neighborhoods and neighborhoods that became Asian and Hispanic destinations remained ungentrified despite the growth of gentrification during the late twentieth century. The findings suggest that the rise of immigration after 1965 brought pioneers to many low-income central-city neighborhoods, spurring gentrification in some neighborhoods and forming ethnic enclaves in others.

    2015-01-01

    Western observatories became scientific factories from the mid-19th century. Astrometry symbolized the transition to an industrious economy of scientific practices. The printing chronograph, which reduced the personal equations of the observers, was, first in the United States, then in England, the symbolic instrument of this transformation. In France, the initiatives of the astronomer Liais were prototypical. In the practices of the Hendaye Observatory, and thanks to the abbé Verschaffel, the printing chronograph made its definitive entry in French observatories at the beginning of the 20th century. Excessive centralization of French astronomy, the authoritarianism of Urbain Le Verrier, the director of the Paris Observatory, and the poor market for scientific instruments explain why the printing chronograph took root, belatedly, in France.

    Robotic surgery is the newst technologic option in urology. To understand how new robots work is interesting to know their history. The desire to design machines imitating humans continued for more than 4000 years. There are references to King-su Tse (clasic China) making up automaton at 500 a. C. Archytas of Tarentum (at around 400 a.C.) is considered the father of mechanical engineering, and one of the occidental robotics classic referents. Heron of Alexandria, Hsieh-Fec, Al-Jazari, Roger Bacon, Juanelo Turriano, Leonardo da Vinci, Vaucanson o von Kempelen were robot inventors in the middle age, renaissance and classicism. At the XIXth century, automaton production underwent a peak and all engineering branches suffered a great development. At 1942 Asimov published the three robotics laws, based on mechanics, electronics and informatics advances. At XXth century robots able to do very complex self governing works were developed, like da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale, CA, USA), a very sophisticated robot to assist surgeons.

    This article examined i) how traditional medico-pharmaceutical custom from the late 19th century influenced such changes, ii) how medical laws of Daehan Empire and early colonial period influenced the differentiation of medico-pharmaceutical profession, and iii) what the responses of medico-pharmaceutical professionals were like, and arrived at following conclusions. First, in late Chosun, there was a nationwide spread of pharmacies (medicine room, medicine store) as general medical institutions in charge of prescription and medication as well as diagnosis. Therefore, Koreans' perception of Western medicine was not very different from that of traditional pharmacy. Second, Western pharmacies were established by various entities including oriental doctors, Western doctors and drug manufacturers.Their business ranged from medical consultation, prescription, medication and drug manufacture. This was in a way the extension of traditional medico-pharmaceutical custom, which did not draw a sharp line between medical and pharmaceutical practices. Also, regulations on medical and pharmaceutical business of Daehan Empire did not distinguish oriental and Western medicine. Third, clinics attached to pharmacy began to emerge after 1908, as some Western pharmacies that had grown their business based on selling medicine began to hire doctors trained in Western medicine. This trend resulted from Government General's control over medico-pharmaceutical business that began in 1908, following a large-scale dismissal of army surgeons trained in medical schools in 1907. Fourth, as specialization increased within medico-pharmaceutical business following the colonial medical law in early 1910s, such comprehensive business practices as Western pharmacy disappeared and existing businesses were differentiated into dealers of medical ingredients, drug manufacturer, patent medicine businessmen and herbalists. And private practice gradually became the general trend by establishment of medical

    This paper reviews manifestations of racism in European and American histories of Arab and Persian astronomy from the eighteenth century to the present day. Its first section discusses representation of Islamic astronomy from Adam Smith to late Victorian writers, particularly tracing ideas of Arab unoriginality and scientific incapacity. The second section first relates the appearance of scientific racism in the early twentieth-century historiography of astronomy, then how the rise of scientifically and linguistically competent scholarship in the latter twentieth century provided much-improved information on Islamic achievements in astronomy. The paper’s conclusion underlines the importance of avoiding ethnic supremacism and integrating research on Islamic astronomy into teaching and publishing on the history of astronomy.

    McCabe, Gregory J.; Fountain, Andrew G.

    2013-01-01

    Glaciers of the conterminous United States have been receding for the past century. Since 1900 the recession has varied from a 24 % loss in area (Mt. Rainier, Washington) to a 66 % loss in the Lewis Range of Montana. The rates of retreat are generally similar with a rapid loss in the early decades of the 20th century, slowing in the 1950s–1970s, and a resumption of rapid retreat starting in the 1990s. Decadal estimates of changes in glacier area for a subset of 31 glaciers from 1900 to 2000 are used to test a snow water equivalent model that is subsequently employed to examine the effects of temperature and precipitation variability on annual glacier area changes for these glaciers. Model results indicate that both winter precipitation and winter temperature have been important climatic factors affecting the variability of glacier variability during the 20th Century. Most of the glaciers analyzed appear to be more sensitive to temperature variability than to precipitation variability. However, precipitation variability is important, especially for high elevation glaciers. Additionally, glaciers with areas greater than 1 km2 are highly sensitive to variability in temperature.

    PubMed

    Yu, Xiaobo

    2017-12-01

    The paper examines the social, cultural and disciplinary factors that influenced the reception and appropriation of Darwinism by China's first generation paleontologists. Darwinism was mixed with Social Darwinism when first introduced to China, and the co-option of Darwinian phrases for nationalistic awakening obscured the scientific essence of Darwin's evolutionary theory. First generation Chinese paleontologists started their training in 1910s-1920s. They quickly asserted their professional identity by successfully focusing on morphology, taxonomy and biostratigraphy. Surrounded by Western paleontologists with Lamarckian or orthogenetic leanings, early Chinese paleontologists enthusiastically embraced evolution and used fossils as factual evidence; yet not enough attention was given to mechanistic evolutionary studies. The 1940s saw the beginning of a new trend for early Chinese paleontologists to incorporate more biological and biogeographical components in their work, but external events such as the dominance of Lysenkoism in the 1950s made the Modern Synthesis pass by without being publicly noticed in Chinese paleontology. Characterized by the larger goal of using science for nation building and by the utilitarian approach favoring local sciences, the reception and appropriation of Darwinism by first generation Chinese paleontologists raise important questions for studying the indigenizing efforts of early Chinese scientists to appropriate Western scientific theories.

  19. Is Psychiatry Scientific? A Letter to a 21st Century Psychiatry Resident

    PubMed Central

    2013-01-01

    During the development of the DSM-5, even the lay press questioned psychiatr's scientific validity. This review provides 21st century psychiatry residents with ways of answering these attacks by defining the concepts and history of psychiatry (a branch of medicine), medicine and science. Psychiatric language has two levels: first, describing symptoms and signs (19th century descriptive psychopathology developed in France and Germany), and second, describing disorders (psychiatric nosology was developed in the early 20th century by Kraepelin and resuscitated by the US neo-Kraepelinian revolution leading to the DSM-III). Science is a complex trial-and-error historical process that can be threatened by those who believe too much in it and disregard its limitations. The most important psychiatric advances, electroconvulsive therapy and major psychopharmacological agents, were discovered by "chance", not by scientific planning. Jaspers's General Psychopathology is a complex 100-year-old book that describes: 1) psychiatric disorders as heterogeneous and 2) psychiatry as a hybrid scientific discipline requiring a combination of understanding (a social science method) and explanation (a natural science method). In the 21st century Berrios reminds us of psychiatry's unfortunate methodological issues due to hybrid symptoms and disorders, some of which are better understood as problems in communication between interacting human beings; in those situations neuroscience methods such as brain imaging make no sense. A new language is needed in psychiatry. East Asian psychiatry residents, who are not particularly attached to the antiquated language currently used, may be particularly equipped for the task of recreating psychiatric language using 21st century knowledge.

    Florence Nightingale lived and worked in response to her times--yet also ahead of her time. She insisted on pursuing a career even though her wealthy family could have provided her with a lifetime of leisure. Because she was a woman, this choice to work outside her home was all the more unusual. Nightingale was also a vanguard woman because she chose nursing, a role that was considered the work of desperate, impoverished women who lived on the street like prostitutes. In addition to these unusual choices, Nightingale's career was unique beyond anyone in her time. She was one of the most prolific authors of the 19th century. In addition to being an early role model for nursing, Nightingale was also a leader in several other fields emerging in her time, including social work, statistical analysis, and print journalism. As a global thinker, Nightingale would have loved 21st century. She noted cultural, social, and economic concerns, particularly in relation to health and to the discipline of nursing. She urged nurses to progress in their practice and to think outside their official domains. She responded to the culture of the 19th century by envisioning what could be changed. Working with her talents and available resources, she evolved the health care culture of the 20th century and beyond. She called all of this work "Health-Nursing." As we remember and further study the extraordinary panorama that is our Nightingale legacy, we are creating and shaping our relevant, emerging 21st century nursing practice.

  2. American marriage in the early twenty-first century.

    PubMed

    Cherlin, Andrew J

    2005-01-01

    During the past century the U.S. family system has seen vast changes--in marriage and divorce rates, cohabitation, childbearing, sexual behavior, and women's work outside the home. Andrew Cherlin reviews these historic changes, noting that marriage remains the most common living arrangement for raising children, but that children, especially poor and minority children, are increasingly likely to grow up in single-parent families and to experience family instability. Cherlin describes the economic and cultural forces that have transformed family life. Job market changes have drawn married women into the work force and deprived less-educated men of the blue-collar jobs by which they traditionally supported their families. And effective contraception and legalized abortion have eroded the norm of marriage before childbearing. Cherlin notes that sentiment in favor of marriage appears to be stronger in the United States than in other developed countries. The share of U.S. adults who are likely to marry is higher, but so is the share likely to divorce. U.S. children are also more likely to live in single-parent families at some time in their childhood. Although nearly all Americans, whether poor or well-to-do, hold to marriage as an ideal, today marriage is increasingly optional. To a greater extent than ever before, individuals can choose whether to form a family on their own, in a cohabiting relationship, or in a marriage. Given U.S. patterns of swift transitions into and out of marriage and high rates of single parenthood, American policymakers eager to promote marriage are unlikely to be able to raise U.S. family stability to levels typical of other developed countries. Consequently, a family policy that relies too heavily on marriage will not help the many children destined to live in single-parent and cohabiting families--many of them poor--during their formative years. Assistance must be directed to needy families, regardless of their household structure

    The present work is carried out in the frame of the KLIMHIST PROJECT ("Reconstruction and model simulations of past climate in Portugal using documentary and early instrumental sources, 17th-19th century)", and is devoted to the study of hydro-meteorological extreme events during the last 350 years, in order to understand how they have changed in time and compare them with current analogues. More specifically, the results selected to this presentation will focus on some hydro-meteorological extreme events of the 18th century, like severe droughts, heavy precipitation episodes and windstorms. One of the most noteworthy events was the winterstorm Bárbara (3rd to 6th December 1739), already studied in prior investigations (Taborda et al, 2004; Pfister et al, 2010), a devastating storm with strong impacts in Portugal caused by violent winds and heavy rainfall. Several other extreme events were detected by searching different documentary archives, including individual, administrative and ecclesiastic sources. Moreover, a more detailed insight to the 1783-1787 period will be made with regard the Lisbon region, taking into consideration the availability of information for daily meteorological observations as well as documentary evidences, like descriptions from Gazeta de Lisboa, the periodic with more continuous publication in the 18thcentury.

    A special place in the reconstruction of climate dynamics takes an analysis of extraordinary meteorological phenomena. These extreme weather events in the first place impact the functioning of, the rhythm and dynamics of the landscapes and determine not only the features of economy, but also certain aspects of historical development. In the analysis of primary chronicles and published data, along with the direct climatic characteristics (hot, warm, cold, wet, dry, etc.) a lot of attention was paid to abnormal (extreme) natural phenomena and indirect indications of climate variability (floods, crop failures, hunger years, epidemics, etc.). As a result, tables were compiled reflecting climatic basic characteristics and extremes for each year since 900 BC. X-XI centuries was a period of minor climatic optimum - the climate was warmer and drier than the modern one. In addition to higher temperatures (up to 1-3C above than mordern), during this period there were no severe winters. A small amount of summer rainfall has led to a reduction in the number of small water reservoirs and flooding rivers. This is evidenced by Slavic settlements on floodplains of a number of rivers in the Moscow region. It is in this favorable climatic time the way "from the Vikings to the Greeks" was open. Catastrophic natural events had a minimum repeatability. For example, during the X century the Russian chronicles mentioned 41 extreme event, but for the XIII century - 102. Most of the villages and towns were located on the low floodplain terraces of rivers. The main farmland was concentrated there as well. In the "period of contrasts" (XIII - XIV centuries) there was an increase of intra-seasonal climate variability, humidity and widespread reduction in summer temperatures by 1-2C. The number of extreme weather events increased: cold prolonged winters, long rains in summers, cold weather returns in the early summer, early frosts in late summer - early autumn. Such conditions often

Again, there is tension between unregulated economic development based on local control and strong centralized decision making, but the 21st century has inadequate international political institutions. National corporations did not fit into the institutional context of the 19th century. Multinational corporations do not fit the political institutions extant in the early 21st century. Hutton's insight about geologic time can be applied to politics. Time scale is important in understanding political as well as geologic processes. Policy trends begin with electoral surges and are sustained with subsequent incremental election results and consensus. Geoscientists of the 21st century may be able to look to their 19th century colleagues to recognize the level of political energy needed to convincingly explain the policy consequences of their data to elected officials. Geoscience influence in the policy process is critical to building a lasting political consensus for sustainable policy choices.

    This chapter examines connections between research in music, neurology, and psychology during the late-nineteenth century. Researchers in all three disciplines investigated how music is processed by the brain. Psychologists and comparative musicologists, such as Carl Stumpf, thought in terms of multiple levels of sensory processing and mental representation. Early thinking about music processing can be linked to the start of Gestalt psychology. Neurologists such as August Knoblauch also discussed multiple levels of music processing, basing speculation on ideas about language processing. Knoblauch and others attempted to localize music function in the brain. Other neurologists, such as John Hughlings Jackson, discussed a dissociation between music as an emotional system and language as an intellectual system. Richard Wallaschek seems to have been the only one from the late-nineteenth century to synthesize ideas from musicology, psychology, and neurology. He used ideas from psychology to explain music processing and audience reactions and also used case studies from neurology to support arguments about the nature of music. Understanding the history of this research sheds light on the development of all three disciplines-musicology, neurology, and psychology. © 2015 Elsevier B.V. All rights reserved.

    2016-04-01

    This paper reconstructs the natural philosophical method of Geminiano Montanari, one of the most prominent Italian natural philosophers of the late seventeenth century. Montanari's views are used as a case study to assess recent claims concerning early modern experimental philosophy. Having presented the distinctive tenets of seventeenth-century experimental philosophers, I argue that Montanari adheres to them explicitly, thoroughly, and consistently. The study of Montanari's views supports three claims. First, experimental philosophy was not an exclusively British phenomenon. Second, in spite of some portrayals of experimental philosophy as an 'atheoretical' or 'purely descriptive' enterprise, experimental philosophers could consistently endorse a variety of natural philosophical explanations and postulate theoretical entities. Third, experimental philosophy and mechanical philosophy were not, as such, antagonistic. They could be consistently combined in a single philosophical enterprise. Copyright © 2015 The Author.

    PubMed

    Nam, Sung Hyun

    2015-04-01

    This study aims to examine the beginning and the development of Christian Charities during the 4(th)-6(th) centuries which would eventually result in the birth of the hospital in modern sense in the first half of the 7(th) century. For this purpose, I looked carefully into various primary sources concerning the early Christian institutions for the poor and the sick. Above all, it's proper to note that the first xenodocheion where hospitality was combined with a systematic caring, is concerned with the Trinitarian debate of the 4(th) century. In 356, Eustathios, one of the leaders of homoiousios group, established xenodocheion to care for the sick and the lepers in Sebaste of Armenia, whereas his opponent Aetios, doctor and leader of the heteroousios party, was reckoned to have combined the medical treatment with his clerical activities. Then, Basil of Caesarea, disciple of Eustathios of Sebaste, also founded in 372 a magnificent benevolent complex named 'Basileias' after its founder. I scrupulously analysed several contemporary materials mentioning the charitable institution of Caesarea which was called alternatively katagogia, ptochotropheion, xenodocheion. John Chrysostome also founded several nosokomeia in Constantinople at the end of the 4(th) century and the beginning of the 5(th) century. Apparently, the contemporary sources mention that doctors existed for these Charities, but there is no sufficient proof that these 'Christian Hospitals,' Basileias or nosokomeia of Constantinople were hospitals in modern sense. Imperial constitutions began to mention ptochotropheion, xenodocheion and orphanotropheion since the second half of the 5(th) century and then some Justinian laws evoked nosokomium, brephotrophia, gerontocomia. These laws reveal that 'Christian Hospitals' were well clarified and deeply rooted in Byzantine society already in these periods. And then, new benevolent institutions emerged in the 6(th) century: nosokomeia for a specific class and

    The man in-the-street who frequently asks the question "Why am I here?" finds even more difficulty with the question "Why are parasites here?" The public's distaste for parasites (and by implication, for parasitologists!) is therefore understandable, as maybe was the feeling of early 20th century biologists that parasites were a puzzle because they did not conform to the then widely held association between evolution and progress, let alone the reason why a benevolent Creator should have created them. In mid-century, the writer, contemplating a career in parasitology was taken aback when he found that extolled contemporary biologists disdained parasites or thought little of parasitology as an intellectual subject. These attitudes reflected a lack of appreciation of the important role of parasites in generating evolutionary novelty and speciation, also unawareness of the value of parasite life-cycle studies for formulating questions of wider significance in biology, deficiencies which were gratifyingly beginning to be remedied in the latter half of the century.

  1. From Danger and Motherhood to Health and Beauty: Health Advice for the Factory Girl in Early Twentieth-Century Britain1

    LONG, VICKY; MARLAND, HILARY

    2015-01-01

    A survey of government reports and the archives and journals of other agencies interested in industrial health in early twentieth-century Britain has led us to conclude that, in addition to apprehension about the potentially harmful impact of industrial work on the reproductive health of women, there was a great deal of interest in the health of young, unmarried girls in the workplace, particularly the factory. Adopting a broader time frame, we suggest that the First World War, with its emphasis on the reproductive health of women, was an anomalous experience in a broader trend which stressed the growing acceptability of women’s work within industry. Concern with girls’ health and welfare embraced hygiene, diet, exercise, recreation, fashion and beauty within and outside of the workplace, as well as the impact of the boredom and monotony associated with industrial work. The health problems of young women workers tended to be associated with behaviour and environment rather than biology, as were anxieties about the impact of work on morals, habits and character. Efforts to ensure that young female factory workers would be equipped to take their place as citizens and parents, we argue, often dovetailed rather than diverged with the ‘boy labour’ question.

    Edward Titchener (1867-1927) is one of the most prominent figures in the history of American psychology from the early 20th century. Accordingly, his psychological system-structuralism-has received due attention in the secondary literature. However, a closer look at traditional interpretations of the development of Titchener's ideas reveals a series of missing elements, such as his early studies before going to Leipzig. The central goal of this article is to present the main elements of Titchener's intellectual education in Oxford, thereby showing the influence of the British tradition of the 19th century upon his early intellectual development. On the basis of hitherto unexplored primary sources, we discuss Titchener's relationship with British idealism and scientific naturalism, two movements that shaped a significant part of British psychological thinking in the 19th century. We conclude that Titchener's Oxford years are much more relevant to understanding his intellectual development than the literature has so far assumed.

  7. Early 20th-century research at the interfaces of genetics, development, and evolution: reflections on progress and dead ends.

    PubMed

    Deichmann, Ute

    2011-09-01

    Three early 20th-century attempts at unifying separate areas of biology, in particular development, genetics, physiology, and evolution, are compared in regard to their success and fruitfulness for further research: Jacques Loeb's reductionist project of unifying approaches by physico-chemical explanations; Richard Goldschmidt's anti-reductionist attempts to unify by integration; and Sewall Wright's combination of reductionist research and vision of hierarchical genetic systems. Loeb's program, demanding that all aspects of biology, including evolution, be studied by the methods of the experimental sciences, proved highly successful and indispensible for higher level investigations, even though evolutionary change and properties of biological systems up to now cannot be fully explained on the molecular level alone. Goldschmidt has been appraised as pioneer of physiological and developmental genetics and of a new evolutionary synthesis which transcended neo-Darwinism. However, this study concludes that his anti-reductionist attempts to integrate genetics, development and evolution have to be regarded as failures or dead ends. His grand speculations were based on the one hand on concepts and experimental systems that were too vague in order to stimulate further research, and on the other on experiments which in their core parts turned out not to be reproducible. In contrast, Sewall Wright, apart from being one of the architects of the neo-Darwinian synthesis of the 1930s, opened up new paths of testable quantitative developmental genetic investigations. He placed his research within a framework of logical reasoning, which resulted in the farsighted speculation that examinations of biological systems should be related to the regulation of hierarchical genetic subsystems, possibly providing a mechanism for development and evolution. I argue that his suggestion of basing the study of systems on clearly defined properties of the components has proved superior to

    Although infrared radiation was described by W. Herschel already in 1800, technical problems delayed its use in astronomy for 160 years. After the invention of a sensitive bolometer and semiconducting CCD arrays for very wide infrared window the progress in the field accelerated. Many high-altitude observatories started their work in the last three decades of XXth century and since 1983 space observatories became most important due to the fact that infrared radiation penetrates through opaque cold shells. Moreover, cosmological expansion of the Universe shifts the maximum of spectral energy of distant hot objects from ultraviolet to near infrared region. Infrared astronomy is also essential for improving our knowledge of the cold universe, particularly for studies about the birth of stars, planetary systems and galaxies.

    PubMed Central

    2014-01-01

    In the early 21st century, sports concussion has become a prominent public health problem, popularly labeled “The Concussion Crisis.” Football-related concussion contributes much of the epidemiological burden and inspires much of the public awareness. Though often cast as a recent phenomenon, the crisis in fact began more than a century ago, as concussions were identified among footballers in the game’s first decades. This early concussion crisis subsided—allowing the problem to proliferate—because work was done by football’s supporters to reshape public acceptance of risk. They appealed to an American culture that permitted violence, shifted attention to reforms addressing more visible injuries, and legitimized football within morally reputable institutions. Meanwhile, changing demands on the medical profession made practitioners reluctant to take a definitive stance. Drawing on scientific journals, public newspapers, and personal letters of players and coaches, this history of the early crisis raises critical questions about solutions being negotiated at present.

  12. A century of Dutch neurology.

    Koehler, P J; Bruyn, G W; Moffie, D

    1998-12-01

    The Netherlands Society of Neurology evolved from the Society of Psychiatry founded in 1871. The name was changed into Netherlands Society of Psychiatry and Neurology (NSPN) in 1897. In the same year, the word neurology was also added to the name of the journal. The Society steadily blossomed, but in 1909 the first signs of dissatisfaction occurred: the Amsterdam Neurologists Society was founded. A few split-offs would follow. The number of members of the NSPN increased from 205 in 1920 to 585 in 1960. In the early 1960s, the Society was reorganised and would consist of two sections, one for psychiatry and one for neurology. However, this would not last, as a full separation was established in 1974. For several reasons, the name of the journal was changed four times until it assumed its present name in 1974. The 100th volume of CNN was not published, as expected. in 1996, but in 1998, because of two skipped publication years, one during WWII and another in the 1970s. During the last decades of the nineteenth century, teaching of neurology was mostly given within the frame of psychiatry, following the German tradition of 'brainpsychiatry' (organic or biologic psychiatry). The first official chair of psychiatry was founded at Utrecht, 1893 (Winkler). In Amsterdam, private teachers such as Delprat taught 'electro-therapy and nervous diseases' since the 1880s. The first extraordinary chair of neurology and electrotherapy was founded for his successor, Wertheim Salomonson in 1899. The first university clinic for psychiatry and neurology started at the Amsterdam Municipal University, when Winkler became professor of psychiatry and neurology in Amsterdam in 1896. Around the turn of the century, chairs of psychiatry and neurology were also founded in Groningen and Leiden. Separate chairs for neurology and psychiatry appeared in Amsterdam in 1923 and in Utrecht in 1936. Following an initiative of Brouwer, the first neurological university clinic opened its doors in

    2011-01-01

    This article explores the status, apparatus and character of forensic pathology in the inter-war period, with a special emphasis on the ‘people’s pathologist’, Bernard Spilsbury. The broad expert and public profile of forensic pathology, of which Spilsbury was the most prominent contemporary representative, will be outlined and discussed. In so doing, close attention will be paid to the courtroom strategies by which he and other experts translated their isolated post-mortem encounters with the dead body into effective testimony. Pathologists built a high-profile practice that transfixed the popular, legal and scientific imagination, and this article also explores, through the celebrated 1925 murder trial of Norman Thorne, how Spilsbury’s courtroom performance focused critical attention on the practices of pathology itself, which threatened to destabilise the status of forensic pathology. In particular, the Thorne case raised questions about the interrelation between bruising and putrefaction as sources of interpretative anxiety. Here, the question of practice is vital, especially in understanding how Spilsbury’s findings clashed with those of rival pathologists whose autopsies centred on a corpse that had undergone further putrefactive changes and that had thereby mutated as an evidentiary object. Examining how pathologists dealt with interpretative problems raised by the instability of their core investigative object enables an analysis of the ways in which pathological investigation of homicide was inflected with a series of conceptual, professional and cultural difficulties stemming in significant ways from the materiality of the corpse itself. This article presents early findings of a larger study of twentieth-century English homicide investigation which focuses on the interaction between two dominant forensic regimes: the first, outlined in part here, is a body-centred forensics, associated with the lone, ‘celebrity’ pathologist, his scalpel and

The broad expert and public profile of forensic pathology, of which Spilsbury was the most prominent contemporary representative, will be outlined and discussed. In so doing, close attention will be paid to the courtroom strategies by which he and other experts translated their isolated post-mortem encounters with the dead body into effective testimony. Pathologists built a high-profile practice that transfixed the popular, legal and scientific imagination, and this article also explores, through the celebrated 1925 murder trial of Norman Thorne, how Spilsbury's courtroom performance focused critical attention on the practices of pathology itself, which threatened to destabilise the status of forensic pathology. In particular, the Thorne case raised questions about the interrelation between bruising and putrefaction as sources of interpretative anxiety. Here, the question of practice is vital, especially in understanding how Spilsbury's findings clashed with those of rival pathologists whose autopsies centred on a corpse that had undergone further putrefactive changes and that had thereby mutated as an evidentiary object. Examining how pathologists dealt with interpretative problems raised by the instability of their core investigative object enables an analysis of the ways in which pathological investigation of homicide was inflected with a series of conceptual, professional and cultural difficulties stemming in significant ways from the materiality of the corpse itself. This article presents early findings of a larger study of twentieth-century English homicide investigation which focuses on the interaction between two dominant forensic regimes: the first, outlined in part here, is a body-centred forensics, associated with the lone, 'celebrity' pathologist, his scalpel and the mortuary

  16. Can we conquer cancer in the twenty-first century?

    The twentieth century recorded the greatest advance in the control of human disease. From the beginning of recorded time, the human life-span changed little until the twentieth century. In the USA, it increased from 47.3 years in 1900 to 76.4 years in 2000. The answer to the question of "Can we cure cancer in the twenty-first century?" requires an appreciation of the contemporary nature of our knowledge. At the beginning of the twentieth century, major problems were nutrition and infection. By 1950, the major causes of mortality and morbidity were still infectious diseases, such as syphilis, tuberculosis, poliomyelitis, and influenza. The 1950s and 1960s were the golden age of control of infectious diseases, while cancer, because of the aging of the population and the strong association between cancer and age, has become the major healthcare problem of the twenty-first century. Until 1960, no one had proposed or demonstrated that a systemic or metastatic form of cancer could be cured. In only 35-40 years not only have techniques for the early detection, prevention, and surgical and radiation therapy treatments improved, but at least 15-20% of patients with systemic/metastatic cancers can be cured with our current primitive systemic treatments. Prior to 1943, there was no chemotherapy. Prior to 1948, no one had described complete regression of a systemic cancer. There were no multi-institution, randomized clinical trials prior to 1949. Additionally, combination chemotherapy, new drugs, bone marrow transplantation, broad-spectrum antibiotics to control infections, and platelets to control hemorrhage have been added in the past 50 years. The pace of progress extrapolates to a prediction of cancer control in the twenty-first century. The human genome has been sequenced, and it will be possible to identify expression profiles not only for malignant cells but for their normal counterparts. It is certain that interventions specific for control of the malignant

  17. Global generations: social change in the twentieth century.

    The concept of generation within sociology has until recently been a marginal area of interest. However, various demographic, cultural and intellectual developments have re-awakened an interest in generations that started with the classic essay by Karl Mannheim. To date, the sociological literature has generally conceptualized generations as nationally bounded entities. In this paper we suggest that the sociology of generations should develop the concept of global generations. This conceptual enhancement is important because the growth of global communications technology has enabled traumatic events, in an unparalleled way, to be experienced globally. The late nineteenth and early twentieth century was the era of international generations, united through print media, and the mid-twentieth century saw the emergence of transnational generations, facilitated by new broadcast communications. However, the latter part of the twentieth century is the period of global generations, defined by electronic communications technology, which is characterized, uniquely, by increasing interactivity. The 1960s generation was the first global generation, the emergence of which had world-wide consequences; today with major developments in new electronic communications, there is even more potential for the emergence of global generations that can communicate across national boundaries and through time. If in the past historical traumas combined with available opportunities to create national generations, now globally experienced traumas, facilitated by new media technologies, have the potential for creating global generational consciousness. The media have become increasingly implicated in the formation of generational movements. Because we are talking about generations in the making rather than an historical generation, this article is necessarily speculative; it aims to provoke discussion and establish a new research agenda for work on generations.

    A standardized tree-ring width chronology of the Scots pine (Pinus sylvestris L.) along with different types of documentary evidence (e.g. annals, chronicles, diaries, private correspondence, records of public administration, early newspapers) have been used to reconstruct air temperature in Poland. The ground surface temperature (GST) history has been reconstructed based on the continuous temperature logs from 13 wells, using a new method developed recently by Harris and Chapman (1998; Journal of Geophysical Research 103: 7371-7383) which is compared with the functional space inversion (FSI) method applied to all available Polish temperature-depth profiles analysed before.Response function calculations conducted for trees growing in Poland (except in mountainous regions) reveal a statistically significant correlation between the annual ring widths of the Scots pine and the monthly mean air temperatures, particularly from February and March, but also from January and April. Therefore, it was only possible to reconstruct the mean January-April air temperature.The following periods featured a warm late winter/early spring: 1530-90, 1656-70 (the warmest period), 1820-50, 1910-40, and after 1985. On the other hand, a cold January-April occurred in the following periods: 1600-50, 1760-75, 1800-15, 1880-1900, and 1950-80.Reconstructions of thermal conditions using documentary evidence were carried out for winter (December-February) and summer (June-August) from 1501 to 1840 and, therefore, their results cannot be directly compared with reconstructions based on tree-ring widths. Winter temperatures in this period were colder than air temperature in the 20th century. On the other hand, historical summers were generally warmer than those occurring in the 20th century. Such situations dominated in the 16th and 17th centuries, as well as at the turn of the 18th and 19th centuries. Throughout almost the entire period from 1501 to 1840, the thermal continentality of the climate

    From the early century Nobel Prize winning (1923) experiments with charged oil droplets, resulting in the discovery of the elementary electronic charge by Robert Millikan, to the early 21st century Nobel Prize (2002) awarded to John Fenn for his invention of electrospray ionization mass spectroscopy and its applications to proteomics, electrostatic processes have been successfully applied to many areas of industry and medicine. Generation, transport, deposition, separation, analysis, and control of charged particles involved in the four states of matter: solid, liquid, gas, and plasma are of interest in many industrial and biomedical processes. In this paper, we briefly discuss some of the applications and research needs involving charged particles in industrial and medical applications including: (1) Generation and deposition of unipolarly charged dry powder without the presence of ions or excessive ozone, (2) Control of tribocharging process for consistent and reliable charging, (3) Thin film (less than 25 micrometers) powder coating and Powder coating on insulative surfaces, (4) Fluidization and dispersion of fine powders, (5) Mitigation of Mars dust, (6) Effect of particle charge on the lung deposition of inhaled medical aerosols, (7) Nanoparticle deposition, and (8) Plasma/Corona discharge processes. A brief discussion on the measurements of charged particles and suggestions for research needs are also included.

    2003-01-01

    This study supplemented by three charts and a list of biographies, is, for the first time, encompassing their life-data, their resumés and even their professional careers as well as political commitments shown by more than 200 Silesian students. They, at the University of Breslau, but also at other German universities, had joined the student fraternities in the 20-ies and early 30-ies of the 19th century and, in consequence, were persecuted by state authorities, notably in Prussia and, in the majority of cases, had been sentenced to prison terms of varying degrees. The first demagogic persecution, which happened in the first half of the twenties, culminating in 1822 in the Breslau Arminen Trail and ending up with the staging of the Youth-Association-Trail in 1826, had implicated about 100 Silesians, with a smaller portion of them - apart from teh three Youth-Association Silesians who were sentenced to five years imprisonment in a fortress - getting away with a relatively short "political fortress imprisonment". Later a considerable part of them made a career in the prussian judicial authority, in the institutions of higher learning, as parish priests, physicians and scientists, whereas any political engagement remained a rare exception. Out of the 137 Silesian members of the student fraternities affected by the second wave of persecution, the overwhelming majority of them being Protestants and originating partly from the middle classes, mostly artisans, and from intellectual background, with about a hundred of them being given essentially higher sentences ranging from six years up to capital punishment and, in the event of reprieves, they had to serve their sentences between six months and four-to-six years in a fortress. The majority of them made a medium-level professional career, never exceeding the medium ranks, as judicial officers, lawyers in state or communal services, parish priests, teachers or physicians. However, from this group of persecuted persons, a

  6. Reconstructing Early Industrial Contributions to Legacy Trace Metal Contamination in Southwestern Pennsylvania

    The remobilization of legacy contamination stored in floodplain sediments remains a threat to ecosystem and human health, particularly with potential changes in global precipitation patterns and flooding regimes. Vehicular and industrial emissions are often the dominant, recognized source of anthropogenic trace metal loadings to ecosystems today. However, loadings from early industrial activities are poorly characterized and potential sources of trace metal inputs. While potential trace metal contamination from these activities is recognized (e.g., the historical use of lead arsenate as a pesticide), the magnitude and distribution of legacy contamination is often unknown. This presentation reconstructs a lake sediment record of trace metal inputs from an oxbow lake in Southwestern Pennsylvania. Sediment cores were analyzed for major and trace metal chemistry, carbon to nitrogen ratios, bulk density, and magnetic susceptibility. Sediment trace metal chemistry in this approximately 250 year record (180 cm) record changes in land use and industry both in the 19th century and the 20th century. Of particular interest is early 19th century loadings of arsenic and calcium to the lake, likely attributable to pesticides and lime used in tanning processes near the lake. After this period of tanning dominated inputs, sediment barium concentrations rise, likely reflecting the onset of coal mining operations and resulting discharge of acid mine drainage to surface waters. In the 20th century portion of our record (70 -20 cm), patterns in sediment zinc, cadmium, and lead concentrations are dominated by the opening and closing of the nearby Donora Zinc Works and the American Steel & Wire Works, infamous facilities in the history of air quality regulation. The most recent sediment chemistry records periods include the enactment of air pollution legislation (~ 35 cm), and the phase out of tetraethyl leaded gasoline (~30 cm). Our study documents the impact of early industry in the

  8. Epidemiologic trends of leprosy for the 21st century.

    2016-01-01

    Major gaps still exist in the knowledge about leprosy, particularly with regard to how it spreads. Leprosy epidemiology remains complicated due to the specific characteristics of Mycobacterium leprae. To describe epidemiologic trends for the 21st century, the first part of this paper gives an overview of the epidemiology of leprosy, followed by past trends and the present situation of new-case detection as a proxy of the incidence. The third part, regarding predicted epidemiologic trends for the 21st century, elaborates on the main topic of this paper. With limited diagnostic tools to detect infection with M leprae, other methods are necessary to estimate trends in incidence and transmission. A computer program has been developed for modeling the transmission and control of leprosy (SIMLEP). The effect of failure to sustain early case detection beyond 2005 on leprosy incidence and case detection is shown. Important unanswered questions are whether the incubation period is contagious and how rapid close contacts of leprosy patients are infected. As long as such key questions remain unanswered, it will be difficult to estimate the impact of control strategies on the transmission of M leprae on resulting disease incidence. In the meantime we can expect that the global new-case detection trends will stay more or less stable or only decrease slightly for many years to come. There is a need of new preventive interventions to change this situation and reduce the incidence of leprosy in the 21st century. Copyright © 2016 Elsevier Inc. All rights reserved.

  9. Arterial Stiffening in Perspective: Advances in Physical and Physiological Science Over Centuries.

    2016-07-01

    Arterial stiffening is not a new issue in medicine or research but was the prime concern of Richard Bright in the early 19th century and of the prominent London physicians and pathologists who tried to unscramble the relationship between kidney, heart, and cerebrovascular disease and hardness of the pulse in the late 19th century. It was of major concern to medical educators including Osler and Mackenzie who were still active in practice 100 years ago. It is all too easy (when dependent on the Internet) to consider arterial stiffness to be a new issue. The terms arterial stiffness, aortic stiffness, or wave reflection do not appear as categories for articles such as this in respectable journals, nor in categories for meetings of specialized physicians. Yet as described in this article, the subject was of interest to clinicians, to investigators such as Harvey in the 17th century, and to physicists who developed laws and principles of elasticity from the study of biological materials including ligaments and arteries. This paper provides a perspective on arterial stiffness from the time of William Harvey and Isaac Newton to the present, with a glance into the future. © American Journal of Hypertension, Ltd 2016.

  10. Russia and the Medical Drug Trade in the Seventeenth Century

    PubMed Central

    Griffin, Clare

    2018-01-01

    Summary This article deals with the trade in medicines into Russia in the seventeenth century. Both the early modern medical drug trade, and Russian medicine, have previously received substantial attention, but no work has thus far been undertaken on the Russian angle of the drug trade. Drawing on previously unused documents, this article traces the kinds of drugs acquired by the Moscow court. In contrast to the dominant view of official Russian medicine as divorced from native healing practices and fundamentally reliant upon Western European trends, these documents reveal that drugs were sourced as locally as Moscow markets, and from as far afield as East Asia and the Americas, but that not all drugs were accepted. As many of these imports came through Western European markets, this article also sheds further light on what drugs were available there, demonstrating the great diversity of drugs traded in early modern Europe.

  11. How 21st century droughts affect food and environmental security

    NASA Astrophysics Data System (ADS)

    Kogan, Felix

    The first 13th years of the 21st century has begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2-6% and 7-16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This presentation is a travelogue of the 21st century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the NOAA operational space technology, called Vegetation Health (VH), which has the longest period of observation and provide good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI) and thermal conditions. The 21st century droughts in the USA, Russia, Australia Argentina, Brazil, China, India and other principal grain producing countries were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food and environmental security and led to food riots in some countries. This presentation investigate how droughts affect food and environmental security, if they can be detected earlier, how to monitor their area, intensity, duration and impacts and also their dynamics during the climate warming era with satellite-based vegetation health technology.

  13. Immigration, Occupation and Inequality in Emergent Nineteenth-Century New England Cities

    PubMed Central

    Leonard, Susan Hautaniemi; Robinson, Christopher; Anderton, Douglas L.

    2017-01-01

    This paper explores the social interactions of immigration, occupation and wealth in two urban industrial cities of nineteenth century New England that were largely built upon, and shaped by, immigration: the very rapidly growing factory town of Holyoke, Massachusetts and a more mixed market and steadily growing nearby community of Northampton, Massachusetts. Both communities were emergent, rapidly industrializing, inland cities, providing a quite distinct immigration context than large established cities of the East Coast. Both were destinations for the same general ethnic immigration waves over the late nineteenth century, but with very different, and differently impacted, social spaces into which immigrants arrived. Contrasting and considering both these emergent cities allows us to ascertain the extent to which the occupational distribution and accumulation of wealth by immigrant groups supports the broad pattern of nineteenth-century assimilation, and reveals ways in which other migration processes may have been at odds, or intertwined, with the long-term historical assimilation of immigrants in such communities. Our findings support a traditional assimilationist perspective in emergent urban-industrial centers. However, they also reveal the role of universal immiseration in an industrial city dual-labor market in facilitating or forcing assimilation, the temporal advantages for ethnic groups of arriving early in growing settlements, and the more individualistic nature of economic enclaves in gaining advantages over time that did not manifest across broad immigrant or occupational groups.

  14. North Atlantic early 20th century warming and impact on European summer: Mechanisms and Predictability

    NASA Astrophysics Data System (ADS)

    Müller, Wolfgang

    2017-04-01

    During the last century, substantial climate variations in the North Atlantic have occurred, such as the warmings in the 1920s and 1990s. Such variations are considered to be part of the variability known as the Atlantic Multidecadal Variations (AMV) and have a strong impact on local climates such as European summers. Here a synthesis of previous works is presented which describe the occurrence of the warming in the 1920s in the North Atlantic and its impact on the European summer climate (Müller et al. 2014, 2015). For this the 20th century reanalysis (20CR) and 20CR forced ocean experiments are evaluated. It can be shown that the North Atlantic Current and Sub-Polar Gyre are strengthened as a result of an increased pressure gradient over the North Atlantic. Concurrently, Labrador Sea convection and Atlantic meridional overturning circulation (AMOC) increase. The intensified NAC, SPG, and AMOC redistribute sub-tropical water into the North Atlantic and Nordic Seas, thereby increasing observed and modelled temperature and salinity during the 1920s. Further a mechanism is proposed by which North Atlantic heat fluxes associated with the AMV modulate European decadal summer climate (Ghosh et al. 2016). By using 20CR, it can be shown that multi-decadal variations in the European summer temperature are associated to a linear baroclinic atmospheric response to the AMV-related surface heat flux. This response induce a sea level pressure structure modulating meridional temperature advection over north-western Europe and Blocking statistics over central Europe. This structure is shown to be the leading mode of variability and is independent of the summer North Atlantic Oscillation. Ghosh, R., W.A. Müller, J. Bader, and J.

    2009-08-01

    This research describes nurses' experiences in administering "the water cure," hot or cold wet sheet packs, and continuous tub baths in state mental hospitals during the early twentieth century. Student and graduate nurses were required to demonstrate competence in hydrotherapy treatments used to calm agitated or manic patients in the era before neuroleptics. The nurses interviewed for this study indicated that, although labor intensive, hydrotherapy worked, at least temporarily. Although no longer used in state hospitals, hydrotherapy is regaining popularity with the general public and may serve as an adjunct to pharmacological treatments to calm hospitalized patients in the future.

    We present a new analysis of Robert Grosseteste's account of color in his treatise De iride (On the Rainbow), dating from the early 13th century. The work explores color within the 3D framework set out in Grosseteste's De colore [see J. Opt. Soc. Am. A29, A346 (2012)], but now links the axes of variation to observable properties of rainbows. We combine a modern understanding of the physics of rainbows and of human color perception to resolve the linguistic ambiguities of the medieval text and to interpret Grosseteste's key terms.

    2008-01-01

    Considerable literature exists on the benefits of breast feeding on the health and survival of infants and young children, but there is less on the effects on later life outcomes. One such measure of health and well-being that has received attention in the historical literature is terminal adult stature. Information on height is rather widely available; however, it is much more difficult to obtain data on breast feeding. One country that does have such information is Imperial Germany (1871–1919). A number of physicians and local health officials collected information on the incidence and duration of breast feeding early in the 20th century, particularly because of concern about the unusually high infant mortality rates in parts of Germany. Hallie Kintner has surveyed the published results of these studies. The information on the prevalence of breast feeding for the period 1903/10 has been inputed into a database of demographic and economic variables for the counties (Regierungsbezirke) of Germany (1850–1939) There are also published data on heights of military recruits from the Imperial German military forces in 1906. These can be linked to areas in the database and related to breast feeding practices and infant mortality both contemporaneously and approximately 20 years previous to 1906. Results indicate a significant effect of infant feeding practices on later life outcomes operating through infant health conditions, proxied by the infant mortality rate. PMID:18715833

    Rapidly increasing incidence of breast cancer is a new social challenge resulting from a spectrum of internal and external risk factors which appear to be well accepted as an attribute of the early twenty-first century, being, however, new for female sub-populations compared to the past. These include altered socio-economical conditions such as occupational exposure, rotating shift work, specific environmental factors (increased pollution and environmental toxicity, altered dietary habits, quality and composition of meal) as well as consequently shifted and/or adapted physiologic factors such as lower age at menarche, late age of first full-term pregnancy, if any, shorter periods of breastfeeding and later menopause. Consolidated expert statements suggest that over 50 % of all breast cancer cases may be potentially prevented by risk reduction strategy such as regulation of modifiable risk factors. Currently available risk assessment models may estimate potential breast cancer predisposition, in general; however, they are not able to predict the disease manifestation individually. Further, current deficits in risk assessment and effective breast cancer prevention have been recently investigated and summarised as follows: gaps in risk estimation, preventive therapy, lifestyle prevention, understanding of the biology of breast cancer risk and implementation of known preventive measures. This paper overviews the most relevant risk factors, provides recommendations for improved risk assessment and proposes an extended questionnaire for effective preventive measures.

    Until the mid-20th century, mortality rates were often very high during measles epidemics, particularly among previously isolated populations (e.g., islanders), refugees/internees who were forcibly crowded into camps, and military recruits. Searching for insights regarding measles mortality rates, we reviewed historical records of measles epidemics on the Polynesian island of Rotuma (in 1911), in Boer War concentration camps (in 1900-1902), and in US Army mobilization camps during the First World War (in 1917-1918). Records classified measles deaths by date and clinical causes; by demographic characteristics, family relationships (for Rotuma islanders and Boer camp internees), and prior residences; and by camp (for Boer internees and US Army recruits). During the Rotuman and Boer War epidemics, measles-related mortality rates were high (up to 40%); however, mortality rates differed more than 10-fold across camps/districts, even though conditions were similar. During measles epidemics, most deaths among camp internees/military recruits were due to secondary bacterial pneumonias; in contrast, most deaths among Rotuman islanders were due to gastrointestinal complications. The clinical expressions, courses, and outcomes of measles during first-contact epidemics differ from those during camp epidemics. The degree of isolation from respiratory pathogens other than measles may significantly determine measles-related mortality risk.

    Systematic entomology flourished as a branch of Natural History from the 1750s to the end of the nineteenth century. During this interval, the "era of Heroic Entomology," the majority of workers in the field were dedicated amateurs. This article traces the demographic and occupational shifts in entomology through this 150-year interval and into the early twentieth century. The survey is based on entomologists who studied beetles (Coleoptera), and who named sufficient numbers of species to have their own names abbreviated by subsequent taxonomists. In the eighteenth century, 27 entomologists achieved this level of prominence, of whom 37% were academics, 19% were doctors, 11% had private incomes, 19% were clergymen, and 8% were government officials. Many of those with private incomes were members of the European aristocracy, and all but one were European men. The nineteenth century list included 192 entomologists, of whom 17% were academics, 16% were museum curators, 2% were school teachers, 15% were doctors, 6% were military men, 7% were merchants, 2% were government entomologists, 6% had private incomes, 5% were clergymen, 5% were government officials, and 4% were lawyers. The demographics of entomology shifted dramatically in the nineteenth century. Whereas many of the noteworthy entomologists of the eighteenth century were German, Swedish, or French, in the nineteenth century, many more European countries are represented, and almost one-fifth of the noteworthy entomologists were from the United States. The nineteenth century list, like the eighteenth century list, contains no women. By the twentieth century, 63% of 178 noteworthy systematic entomologists were paid professionals, teaching entomology courses in universities, or studying insect taxonomy in museums and government-sponsored laboratories. Only one person on the twentieth century list had a private income, but women (ten individuals) were included on the list for the first time.

  3. Astrometry and early astrophysics at Kuffner Observatory in the late 19th century

    Habison, Peter

    The astronomer and mathematician Norbert Herz encouraged Moriz von Kuffner, owner of the beer brewery in Ottakring, to finance a private scientific observatory in the western parts of Vienna. In the years 1884-87 the Kuffner Observatory was built at the Gallitzinberg in Wien-Ottakring. It was an example of enlighted patronage and noted at the time for its rapid acquisition of new instruments and by increasing international recognition. It contained the largest heliometer in the world and the largest meridian circle in the Austrian-Hungarian Empire. Of the many scientists who worked here we mention Leo de Ball, Gustav Eberhard, Johannes Hartmann and we should not forget Karl Schwarzschild. Here in Vienna he published papers on celestial mechanics, measuring techniques, optics and his fundamental papers concerning photographic photometry, in particular the quantitative determination of the departure of the reciprocity law. The telescope and the associated camera with which he carried out his measurements are still in existence at the observatory. The observatory houses important astronomical instruments from the 19th century. All telescopes were made by Repsold und Söhne in Hamburg, and Steinheil in Munich. These two German companies were best renowned for quality and precision in high standard astronomical instruments. The Great Refractor (270/3500 mm) is still the third largest refractor in Austria. It was installed at the observatory in 1886 and was used together with the Schwarzschild Refractor for early astrophysical work including photography. It is this double refractor, where Schwarzschild carried out his measurements on photographic photometry. The Meridian Circle (132/1500 mm) was the largest meridian passage instrument of the Austro-Hungarian Empire. Today it is the largest meridian circle in Austria and still one of the largest in Europe. The telescope is equipped with one of the first impersonal micrometers of that time. First observations were carried

    The growing evidence of an anthropogenically induced climatic change and the need to compare present-day climate with that of the past centuries, has boosted the search of early meteorological data from all kind of historical archives. Among the documentary data sources, early newspapers deserve special attention. Anonymous observers began to send their data to local newspapers to ensure that people were informed of them. Hardly anything is known of the conditions in which these recording were made, and press collections conserved from late 18th century to mid-19th century are fragmentary. However, it is interesting to analyze the potential of these newspapers as climatic data sources in a period prior to the existence of an official meteorological service. In this work, some examples of Andalusian cities (southern Spain) are analyzed and their utility as data sources is studied: El Mensagero (1796-1797), El Publicista (1812-1813), Diario Constitucional (1820) of Granada, Diario del Gobierno de Sevilla (1812-1813), Diario de Sevilla (1826-1831), Diario de Sevilla de Comercio, Artes y Literatura (1829-1830) of Seville, and Diario Mercantil de Cádiz (1802-1803, 1816-1830) of Cádiz. Future research is outlined.

    A close examination of the literature suggests that the consistent relation between political and welfare state characteristics and infant mortality in the second half of the 20th century in wealthy countries may not be causal. The evolution of infant mortality since the late 19th century was studied in 17 wealthy countries classified according to political traditions, family policy model and period of infant mortality transition. The relation of public health expenditure and income inequality to infant mortality from 1980 to 2005 was also evaluated. The Social Democratic and Scandinavian countries, and those with the earliest transition in infant mortality, had the lowest infant mortality rates until the early 21st century, whereas the late democracies, the Southern European countries, and those in which the transition in infant mortality took place later, had the highest rates until the late 20th century. By the early 21st century, the differences in infant mortality were negligible. Three of the four Scandinavian countries were the first to achieve infant mortality transition, whereas the Southern European countries were the last. The relation between public health expenditure and infant mortality varied depending on the time period in which the analysis was made, and increased income inequality was associated with higher infant mortality. The relation between political and welfare state characteristics and infant mortality in previous studies probably reflects the historical moment in which the transition in infant mortality took place in each country. Methodological limitations do not allow inference of causality in the associations found between welfare state characteristics and infant mortality.

    Outside formal university chemistry classes in Scotland, which existed mainly to fulfil the requirements of medical courses, chemistry teaching was available from extramural lecturers. This form of teaching was often aimed at medical students, who could fulfil their graduation requirements if the lecturer had approved status. However, most of those attending would not have been seeking any formal qualification: there was a wave of enthusiasm among people from many walks of life about gaining chemical knowledge. Audiences included fashionable gentlefolk, manufacturers and industrialists, apprentice surgeons, mechanics, and artisans. Much of the teaching was at a highly proficient level, chemists of the stature of Thomas Thomson, Andrew Ure, Andrew Fyfe, Edward Turner, William Gregory, Thomas Graham, David Boswell Reid and George Wilson all offering classes. For several such teachers, it was the first step in a career that would later lead to significant academic or governmental appointments. In an Appendix, the article lists forty-eight chemists who have been identified as having taught extramurally between the later eighteenth and mid-nineteenth centuries.

    We find robust trends in the area where Antarctic stratospheric temperatures are below the threshold for polar stratospheric cloud (PSC) formation in Goddard Earth Observing System (GEOS) chemistry-climate model (CCM) simulations of the 21st century. In late winter (September-October-November), cold area trends are consistent with the respective trends in equivalent effective stratospheric chlorine (EESC), i.e. negative cold area trends in 'realistic future' simulations where EESC decreases and the ozone layer recovers. In the early winter (April through June), regardless of EESC scenario, we find an increasing cold area trend in all simulations; multiple linear regression analysis shows that this early winter cooling trend is associated with the predicted increase in greenhouse gas concentrations in the future. We compare the seasonality of the potential for Antarctic ozone depletion in two versions of the GEOS CCM and assess the impact of the above-mentioned cold area trends on polar stratospheric chemistry.

    Smallpox was probably the single most lethal disease in eighteenth‐century Britain but was reduced to a minor cause of death by the mid‐nineteenth century due to vaccination programmes post‐1798. While the success of vaccination is unquestionable, it remains disputed to what extent the prophylactic precursor of vaccination, inoculation, reduced smallpox mortality in the eighteenth century. Smallpox was most lethal in urban populations, but most researchers have judged inoculation to have been unpopular in large towns. Recently, however, Razzell argued that inoculation significantly reduced smallpox mortality of adults and older children in London in the last third of the eighteenth century. This article uses demographic evidence from London and Manchester to confirm previous findings of a sudden fall in adult smallpox mortality and a rise in the importance of smallpox in early childhood c. 1770. The nature of these changes is consistent with an increase in smallpox transmission in London and Manchester after 1770 and indicates that smallpox inoculation was insufficient to reduce smallpox mortality in large towns. It remains unclear whether inoculation could have operated to enhance smallpox transmission or whether changes in the properties of the smallpox virus drove the intensification of smallpox mortality among young children post‐1770.

    Cosmology attempts to answer questions concerning the origin of the universe, the way in which it evolves, and the way in which it will end. These are ancient questions that fascinate humanity and attendant metaphysical answers predate recorded history. The dawn of the 21st century has witnessed the first scientific answers. The goal of modern cosmology is to determine the basic properties of the universe. Numerous discoveries have been made in the last century which have had a profound influence on cosmology such as the expansion of the universe and the existence of the cosmic microwave background (CMB). CMB and other phenomena act as fossils for cosmologists who attempt to characterize the early universe through an interpretive methodology similar to that of archaeologists. Programs and tools such as NASA's Cosmic Background Explorer (COBE) have been designed to illuminate the morphologic history of the universe including the big bang theory and the current density of the universe. In this primer for cosmology, these and other discoveries and postulations are discussed.

    A key feature of anticipated 21st century droughts in Southwest North America is the concurrence of elevated temperatures and increased aridity. Instrumental records and paleoclimatic evidence for past prolonged drought in the Southwest that coincide with elevated temperatures can be assessed to provide insights on temperature-drought relations and to develop worst-case scenarios for the future. In particular, during the medieval period, ∼AD 900–1300, the Northern Hemisphere experienced temperatures warmer than all but the most recent decades. Paleoclimatic and model data indicate increased temperatures in western North America of approximately 1 °C over the long-term mean. This was a period of extensive and persistent aridity over western North America. Paleoclimatic evidence suggests drought in the mid-12th century far exceeded the severity, duration, and extent of subsequent droughts. The driest decade of this drought was anomalously warm, though not as warm as the late 20th and early 21st centuries. The convergence of prolonged warming and arid conditions suggests the mid-12th century may serve as a conservative analogue for severe droughts that might occur in the future. The severity, extent, and persistence of the 12th century drought that occurred under natural climate variability, have important implications for water resource management. The causes of past and future drought will not be identical but warm droughts, inferred from paleoclimatic records, demonstrate the plausibility of extensive, severe droughts, provide a long-term perspective on the ongoing drought conditions in the Southwest, and suggest the need for regional sustainability planning for the future.

    Although there were drastic changes in the XX-th century, still 70% of the Hungarian population believe in God, and 10-15% can be counted as active believer. A percentage of 44% of the hospitalised patients indicated a need of pastoral counseling during the treatment time. In the field of psychiatry and psychotherapy the percentage of the need of religious care (pastoral psychology, pastoral counseling) may be even higher. In the field of dentistry the increasing number of psychosomatic patients justify the introduction of such religious treatment methods into the dental care system as well. In this review authors try to collect the main points of this special, religious type of therapy to help dental professionals working in the field of psychosomatic dentistry in the orientation in this interesting and important field.

    2012-01-01

    The paper follows the lives of Mateu Orfila and François Magendie in early nineteenth-century Paris, focusing on their common interest in poisons. The first part deals with the striking similarities of their early careers: their medical training, their popular private lectures, and their first publications. The next section explores their experimental work on poisons by analyzing their views on physical and vital forces in living organisms and their ideas about the significance of animal experiments in medicine. The last part describes their contrasting research on the absorption of poisons and the divergences in their approaches, methods, aims, standards of proof, and intended audiences. The analysis highlights the connections between nineteenth-century courtrooms and experimental laboratories, and shows how forensic practice not only prompted animal experimentation but also provided a substantial body of information and new research methods for dealing with major theoretical issues like the absorption of poisons.

At this time, a botanical preparation, derived from the carnivorous plant Sarracenia purpurea, was proclaimed as being a successful therapy for smallpox infections. The work described characterizes the antipoxvirus activity associated with this botanical extract against vaccinia virus, monkeypox virus and variola virus, the causative agent of smallpox. Our work demonstrates the in vitro characterization of Sarracenia purpurea as the first effective inhibitor of poxvirus replication at the level of early viral transcription. With the renewed threat of poxvirus-related infections, our results indicate Sarracenia purpurea may act as another defensive measure against Orthopoxvirus infections. PMID:22427855

    2006-01-01

    This article focuses on the relationship and mutual influence of astrology and other so-called occult sciences within the context of seventeenth-century New Spain. By presenting some case studies of inquisitorial trials against astrologers, it explores the interrelation between astrological and physiognomical ideas and practices in order to shed some light on the moral dimension of these natural philosophical fields of knowledge. During the early modern period, both astrology and physiognomy were regarded as tools for self-understanding and the understanding of others by means of interpretation of natural signs. Thus their history is key for understanding the shaping of the boundaries between the natural and the moral realms.

    2012-01-01

    This paper examines the history of whooping cough (pertussis) from its first recorded mention in 1190 to the time when its microbial cause was identified. The historical records of the disease are complicated by the variation in the nomenclature employed and through using the same name for disorders with different symptoms. During the early-modern period it was considered to be a disease new to Europe-contagious, dangerous, and potentially epidemic. Believed to be confined to children, its significance was limited until the 18th century when its incidence increased markedly. This essay argues pertussis may have occurred in the late medieval period in individual, though not epidemical, cases.

    Dynamics of commercial fish stocks are generally associated with fishing pressure and climate variability. Due to short time series, past studies of the relationships between fish stock dynamics and climate have mainly been restricted to the last few decades. Here we analyzed a century-long time series of plaice, cod and haddock from the Skagerrak-Kattegat, to assess the long-term influence of climate on recruitment. Recruitment success (RS) was compared against sea-surface temperature (SST) and atmospheric circulation indices on large (North Atlantic) and regional (Skagerrak-Kattegat) scales. Our results show that the influence of climate on RS was more pronounced on longer, than on shorter timescales. Over the century-long period, a shift from low to high climate sensitivity was seen from the early to the late part for plaice and cod, while the opposite was found for haddock. This shift suggests that the increasing fishing pressure and the climate change in the Skagerrak-Kattegat have resulted in an increased sensitivity of RS to climate for plaice and cod. The diminishing of climate sensitivity in haddock RS, on the other hand, may be linked to the early twentieth century collapse of the stock in the region. While no long-term relationship between RS and the Atlantic Multidecadal Oscillation (AMO) could be found, large RS fluctuations during the positive phase of the AMO (1935-1960), relative to the cold phases, suggests a changed pattern in recruitment during warm periods. On the other hand, this could be due to the increased fishing pressure in the area. Thus, reported correlations between climate and fish may be caused by strong trends in climate in the late-twentieth century, and coincident reduction in fish stocks caused by intense fishing, rather than a stable relationship between climate and fish recruitment per se.

    In the 20th century early management of acute pancreatitis often included surgical intervention, despite overwhelming mortality. The emergence of high-quality evidence (randomized controlled trials and meta-analyses) over the past two decades has notably shifted the treatment paradigm towards predominantly non-surgical management early in the course of acute pancreatitis. The present evidence-based review focuses on contemporary aspects of early management (which include analgesia, fluid resuscitation, antibiotics, nutrition, and endoscopic retrograde cholangiopancreatography) with a view to providing clear and succinct guidelines on early management of patients with acute pancreatitis in 2017 and beyond.

    The medicinal chemistry and biomedical applications of gold complexes have been intensively studied over the last decades. Some complexes have been used for the treatment of rheumatoid arthritis, and a considerable number of new metallodrug candidates have been developed as new anticancer drugs and anti-infectives. However, the therapeutic use of gold and its complexes goes back to ancient times and was also of great importance for alchemists until the modern age. In this report, we give an overview of the alchemic medicine between the sixteenth and the early eighteenth century and describe the cytotoxicity and thioredoxin reductase (TrxR) inhibition of a typical "aurum vitae" medicine, which was prepared according to a recipe by Bartholomäus Kretschmar from the seventeenth century. "Aurum vitae" consists of a mixture of gold, mercury and antimony complexes and shows the expected cytotoxic and TrxR inhibitory properties providing some rationale for therapeutic effects of this kind of historical medicinal preparation.

  9. Rabid epidemiologies: the emergence and resurgence of rabies in twentieth century South Africa.

    PubMed

    Brown, Karen

    2011-01-01

    This article discusses the history of rabies in South Africa since the early twentieth century. It argues that rabies is a zoonotic disease that traverses rural and urban spaces, that transfers itself between wild and domestic animals and remains a potential threat to human life in the region. Scientists discovered an indigenous form of rabies, found primarily in the yellow mongoose, after the first biomedically confirmed human fatalities in 1928. Since the 1950s canine rabies, presumed to have moved southwards from across the Zambezi River, has become endemic also. South Africa is home to a comparatively large number of rabies strains and animal carriers, making it a particularly interesting case study. Environmental changes during the colonial and apartheid periods have helped to explain the increase in rabies cases since the mid-twentieth century. Moreover, developments in the biological and ecological sciences have provided insights into why the rabies virus has become endemic in certain wildlife species.

  10. Extraterrestrial Life as the Great Analogy, Two Centuries Ago and in Modern Astrobiology

    NASA Astrophysics Data System (ADS)

    Sullivan, Woodruff T.

    Mainstream ideas on the existence of extraterrestrial life in the late 18th and early 19th centuries are examined, with a focus on William Herschel, one of the greatest astronomers of all time. Herschel viewed all of the planets and moons of our solar system as inhabited, and gave logical arguments that even the Sun, and by extension all of the stars, was a giant planet fit for habitation by intelligent beings. The importance for astrobiology both two centuries ago and now of the type of inductive reasoning called "analogy" is emphasized. Analogy is an imperfect tool, but given that we have only one known case of life and of a life-bearing planet, it is very difficult to make progress in astrobiology without resorting to analogy, in particular between known life and possible other life. We cannot overcome the "N = 1 Problem" without resorting to this "Great Analogy" to guide our research.

    Superconducting magnets for accelerators were first suggested in the mid-60's and have since become one of the major components of modern particle colliders. Technological progress has been slow but steady for the last half-century, based primarily on Nb-Ti superconductor. That technology has reached its peak with the Large Hadron Collider (LHC). Despite the superior electromagnetic properties of Nb3Sn and adoption by early magnet pioneers, it is just now coming into use in accelerators though it has not yet reliably achieved fields close to the theoretical limit. The discovery of the High Temperature Superconductors (HTS) in the late '80's created tremendous excitement, but these materials, with tantalizing performance at high fields and temperatures, have not yet been successfully developed into accelerator magnet configurations. Thanks to relatively recent developments in both Bi-2212 and REBCO, and a more focused international effort on magnet development, the situation has changed dramatically. Early optimism has been replaced with a reality that could create a new paradigm in superconducting magnet technology. Using selected examples of magnet technology from the previous century to define the context, this paper will describe the possible innovations using HTS materials as the basis for a new paradigm.

    How can these finings be interpreted in conclusion? Analysis has revealed firstly that, depending on the chosen period, the socio-geographical situation and the profile of the individual doctor's practice, the clientele varied widely in terms of gender, age and social rank. The consultation behaviour of men and women changed noticeably. Findings overall suggest that up until t8o the gender distribution varied in the individual practices. There was a trend for women to be overrepresented in urban practices during the earlier period. But in general, from the mid-nineteenth century they predominated - in towns as well as in the country in allopathic as well as homeopathic practices. The absence of children, which was bemoaned by many physicians, did not apply to the practices under investigation. On the contrary: the percentage is consistently high while older patients remained underrepresented right up until the end of the period under investigation, even though their proportion increased in the individual practices during the course of the nineteenth century In each of the nineteenth century practices investigated - and increasingly among the lower and middle classes - the physicians' services were used by several members of the same family. We have found no evidence to support the thesis that up until the nineteenth century academic physicians were mainly consulted by aristocratic or wealthy bourgeois patients. The theory probably applies only to early modern urban doctors. In the practices examined here, from the middle of the eighteenth century, patients from all social strata went to consult physicians. The participation of members of the lower classes or from an artisanal, (proto) industrial or agricultural background clearly increased over time 'despite ubiquitous economic and cultural barriers. That the annual numbers of consultations per physician increased - despite the growing number of physicians available - suggests that for economically disadvantaged

  13. Early modern mathematical instruments.

    2011-12-01

    In considering the appropriate use of the terms "science" and "scientific instrument," tracing the history of "mathematical instruments" in the early modern period is offered as an illuminating alternative to the historian's natural instinct to follow the guiding lights of originality and innovation, even if the trail transgresses contemporary boundaries. The mathematical instrument was a well-defined category, shared across the academic, artisanal, and commercial aspects of instrumentation, and its narrative from the sixteenth to the eighteenth century was largely independent from other classes of device, in a period when a "scientific" instrument was unheard of.

    We provide a century-scale view of small-mammal responses to global warming, without confounding effects of land-use change, by repeating Grinnell's early-20th century survey across a 3000-meter-elevation gradient that spans Yosemite National Park, California, USA. Using occupancy modeling to control for variation in detectability, we show substantial ( approximately 500 meters on average) upward changes in elevational limits for half of 28 species monitored, consistent with the observed approximately 3 degrees C increase in minimum temperatures. Formerly low-elevation species expanded their ranges and high-elevation species contracted theirs, leading to changed community composition at mid- and high elevations. Elevational replacement among congeners changed because species' responses were idiosyncratic. Though some high-elevation species are threatened, protection of elevation gradients allows other species to respond via migration.

    2016-01-01

    The concept of "organo clinical-hiatus" prepared by Henri Ey the mid-twentieth century has transcended the boundaries of time and has an amazing utility if it is considered from the point of view of both epistemological and clinical. Current developments in the field of neuroscience on the one hand and effective in clinical practice of psychopathological concepts born in the nineteenth century on the other, pose a challenge for psychiatrists today. It is important not to take a naive position on the new neuroscientific knowledge adopting a dogmatic stance that keeps us patient and while maintaining a clear position that avoids specialty contempt by those who argue that mental illness is a mere construct sustained by the medical hegemonic power. We believe the best way to protect our psychiatric practice of involuntary biases and attacks blinded by reductionist ideas is having a historical knowledge of our discipline and a solid epistemological basis. That way we will have the largest options to help our patients.

    Rappuoli, Rino

    2011-01-01

    In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78–85 years (Crimmins, E. M. & Finch, C. E. 2006 Proc. Natl Acad. Sci. USA 103, 498–503; Kirkwood, T. B. 2008 Nat. Med 10, 1177–1185). In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages. PMID:21893537

  2. Keeping Secrets: Leslie E. Keeley, the Gold Cure and the Nineteenth-Century Neuroscience of Addiction.

    PubMed

    Hickman, Timothy A

    2018-03-25

    Dr Leslie E. Keeley was perhaps the world's most famous addiction cure doctor at the turn of the twentieth century, but mainstream medicine dismissed him as a quack because he dispensed a secret cure. The article aims to describe Keeley's now largely forgotten story and to draw attention to the role of contextual issues in the acceptance or rejection of any theory of addiction, particularly the neuroscientific theories of the early twenty first century. This study is a qualitative assessment and contextualisation of historical documents. Its main sources are archival and are for the most part unknown to historians. The article also offers intellectual and historical context that is drawn from leading historical and sociological analyses. Keeley's addiction cure was dismissed as quackery because it failed to meet the changing standards of late-nineteenth century professional medicine. This begs us to consider contextual issues in any assertion of the viability of addiction therapeutics, in the present as well the past. Keeley's near erasure from the historical record was a consequence of a broader, late-nineteenth century medical power struggle that took precedence over the testimony of tens of thousands of satisfied patients who claimed that Keeley's cure worked. Context matters in the assessment of the viability of theories of addiction from the past but also from the present. Historians and social scientists are well placed to make those assessments.

    17th and 19th centuries were particularly important for the development of the Ottoman medicine. Westernization which had already started in the 17th century continued along the 19th and the early 20th centuries. Turkish physicians began to contact with their European colleagues and in this period Latin medical terminology began to appear in the Ottoman medical literature. Sirvanli Semseddin Itaki's work of the 17th century, the Teşrihü'l Ebdan ve Tercüman-i Kibale-i Feylesufan, is the first illustrated Turkish manuscript of anatomy. The illustrations are qualified as developed examples, compared with the medical literature and knowledge of the period. In the 19th century, Sanizade Mehmet Ataullah Efendi (1771-1826) wrote a modern book of anatomy for the Ottoman medical doctors. Miyarü'l Etibba was one of the earliest printed medical books in Turkish. The second volume of Sanizade's Hamse, Miratü'l Ebdan fi Teşrih-i Azai'l Insan is the first printed Ottoman book on anatomy. In Usulü't-Tabia, the third volume of Hamse, the circulatory system is discussed.

  5. The psychologist as a poet: Kierkegaard and psychology in 19th-century Copenhagen.

    PubMed

    Pind, Jörgen L

    2016-11-01

    Psychology had an early start at the University of Copenhagen in the first half of the 19th century, where it was taught as the major part of a compulsory course required of all first-year students. Particularly important in the establishment of psychology at the university was Frederik Christian Sibbern, who was professor of philosophy from 1813 to 1870. Sibbern wrote numerous works on psychology throughout his career. In his first book on psychology, Sibbern expressed the view that the ideal psychologist should also be a poet. Søren Kierkegaard, Sibbern's student, was precisely such a poet-psychologist. Kierkegaard discussed psychology in many of his works, reflecting the gathering momentum of psychology in 19th-century Copenhagen, Denmark. The article brings out some aspects of Kierkegaard's poetic and literary-imaginative approach to psychology. In his opinion, psychology was primarily a playful subject and limited in the questions about human nature it could answer, especially when it came up against the "eternal" in man's nature. Kierkegaard had a positive view of psychology, which contrasts sharply with his negative views on the rise of statistics and the natural sciences. In the latter half of the 19th century, psychology turned positivistic at the University of Copenhagen. This left little room for Kierkegaard's kind of poetic psychology.

    Mullaney, S

    2015-03-01

    2013 is the tercentenary of the death of Sir Patrick Dun. When Dun died in 1713, he left the proceeds of his estate to enhance medical education in Dublin by funding chairs in medicine. He showed remarkable innovation, but it took 95 years, five Acts of Parliament, two House of Commons enquiries and a House of Lords enquiry before Dun's wishes were brought to fruition and systematic clinical education was available for Dublin medical students. The passage of the final School of Physic Act in 1800 insured that a hospital would open in his name and regular clinical education was provided. The physician, Richard Steevens, who died 3 years earlier in 1710, left the proceeds of his estate to found a hospital, which opened, in his name, in 1733. The contemporary primary sources have been analysed and material from relevant secondary sources has been included where appropriate. Dublin was the beneficiary of these bequests and if circumstances had been more favourable, and the proceeds had been used more efficiently at the start of the eighteenth-century, Dublin could well have rivalled Edinburgh as the seat of medical education in the eighteenth century. In the early nineteenth century, it would fulfil that role and equal Edinburgh as one of the primary centres of medical education in Europe.

  7. Seventeenth-century uplift in eastern Hokkaido, Japan

    2004-01-01

    Shores of eastern Hokkaido rose by perhaps 1 m a few centuries ago. The uplifted area extended at least 50 km along the southern Kuril Trench. It included the estuaries Akkeshi-ko and Hichirippu, on the Pacific coast, and Fu??ren-ko and Onneto??, which open to the Okhotsk Sea. At each estuary, intertidal and subtidal flats rose with respect to tide level; wetland plants colonized the emerging land; and peaty wetland deposits thereby covered mud and sand of the former flats. Previous work at Akkeshi-ko and Onneto?? showed that such emergence occurred at least three times in the past 3000 years. Volcanic-ash layers date the youngest emergence to the seventeenth century AD. New evidence from Akkeshi-ko, Hichirippu and Fu??ren-ko clarifies the age and amount of this youngest emergence. Much of it probably dates from the century's middle decades. Some of the newly emerged land remained above high tides into the middle of the eighteenth century or later. The emergence in the last half of the seventeenth century probably exceeded 0.5 m (inferred from stratigraphy and diatom palaeoecology) without far exceeding 1 m (estimated by comparing seventeenth- and eighteenth-century descriptions of Akkeshi-ko). The stratigraphy and palaeoecology of the emergence are better explained by tectonic uplift than by bay-mouth blockage, tidal-flat accretion or sea-level fall. Eastern Hokkaido needs occasional uplift, moreover, to help reconcile its raised marine terraces with its chronic twentieth-century subsidence. Because it took place above forearc mantle, eastern Hokkaido's seventeenth-century uplift probably lacks analogy with coseismic uplift that occurs above typical plate-boundary ruptures at subduction zones.

    A small collection of antique dental instruments located in the LSU School of Dentistry Library (LSUSD) provides a glimpse into the world of the 19th century dentist. The instruments in this collection, with handles carved from common and rare early materials such as bone, wood, ivory, ebony, cameo, shell and pearl, provide a striking contrast to all-steel instruments of the 20th century. An understanding of their development and function substantially increases appreciation of these instruments, which can be categorized as instruments for oral surgery, prophylaxis, restoration, and general use. In this article, the authors summarize the historical development of each type of instrument and describe the specific items in the LSUSD Library collection.

  12. Testing Drugs and Attesting Cures: Pharmaceutical Monopolies and Military Contracts in Eighteenth-Century France.

    PubMed

    Rivest, Justin

    2017-01-01

    This article explores the role of testing in the allocation of royal monopoly privileges for drugs in eighteenth-century France by following the multi-generational fortunes of a single "secret remedy" from 1713 to 1776: the poudre fébrifuge of the Chevalier de Guiller. On at least five occasions, this drug was tested on patients in order to decide whether it should be protected by a privilege and whether or not its vendors should be awarded lucrative contracts to supply it in bulk to the French military. Although efforts were made early in the century to test the drug through large-scale hospital trials and to relegate privilege granting to a bureaucratic commission, the case of the poudre fébrifuge instead suggests that military expediency and relatively small-scale trials administered personally by royal practitioners remained decisive in determining whether or not a drug received a monopoly privilege or a military contract.

    Vaccine development, which began with Edward Jenner's observations in the late 18th century, has entered its 4th century. From its beginnings, with the use of whole organisms that had been weakened or inactivated, to the modern-day use of genetic engineering, it has taken advantage of the tools discovered in other branches of microbiology. Numerous successful vaccines are in use, but the list of diseases for which vaccines do not exist is long. However, the multiplicity of strategies now available, discussed in this article, portends even more successful development of vaccines.

    The Precambrian is the least-understood part of Earth history, yet it is arguably the most important. Precambrian time spans almost nine-tenths of Earth history, from the formation of the Earth to the dawn of the Cambrian Period. It represents time so vast and long ago that it challenges all comprehension. The Precambrian is the time of big questions. How old is the Earth? How old are the oldest rocks and continents? What was the early Earth like? What was the early atmosphere like? When did life appear, and what did it look like? And, how do we know this? In recent years, remarkable progress has been made in understanding the early evolution of the Earth and life itself. Yet, the scientific story of the early Earth is still a work in progress, humankind's latest attempt to understand the planet. Like previous attempts, it too will change as we learn more about the Earth. Read on to discover what we know now, in the early 21st century.

  18. Universal Principles of Depicting Oneself across the Centuries: From Renaissance Self-Portraits to Selfie-Photographs.

    PubMed

    2017-01-01

    Selfie-photography is generally thought of as a cultural mass phenomenon of the early 21st century, inseparably related to the development and triumph of the smartphone with integrated camera. Western culture, however, has been highly familiar with self-depictions since the Renaissance days. Putting the contemporary selfie into this historic context covering more than five centuries of cultural development from Dürer's (1500) famous "Self-Portrait at 28" (also known as "Selbstbildnis im Pelzrock") to today's Instagram galleries allows for identifying central parallels concerning the technical and social antecedents as well as common underlying psychological factors and shared properties of different kinds of self-depiction. The article provides an overview of the types of contemporary photographic selfies and compares them with painted self-portraits. Finally, this historic perspective leads us to the insight that self-portraits as well as selfies are both referring to nothing less than the "conditio humana."

    2015-01-01

    In this paper we present three newly rediscovered documents from the Royal Society archives that, together with the four described in our previous publications, constitute a set on a cognate theme. The documents were written by, or addressed to, members of the early Royal Society, and their subject is several magisterial formulae, including J. B. van Helmont's alkahest and Ludus. In addition to the interest in those formulae as medicines for various grave illnesses, our analysis showed that some seventeenth-century scholars sought to explain operations of the animal body by invoking similar but natural substances, while attempting to assimilate the latest anatomical discoveries into a novel framework. The complete set of documents sheds some new light on the interests of seventeenth-century networks of scholars concerned with experimenta. PMID:26665488

  20. Music as therapy in early history.

    PubMed

    Thaut, Michael H

    2015-01-01

    The notion of music as therapy is based on ancient cross-cultural beliefs that music can have a "healing" effect on mind and body. Explanations for the therapeutic mechanisms in music have almost always included cultural and social science-based causalities about the uses and functions of music in society. However, it is also important to note that the view of music as "therapy" was also always strongly influenced by the view and understanding of the concepts and causes of disease. Magical/mystical concepts of illness and "rational" medicine probably lived side by side for thousands of years. Not until the late-nineteenth and early-twentieth centuries were the scientific foundations of medicine established, which allowed the foundations of music in therapy to progress from no science to soft science and most recently to actual brain science. Evidence for "early music therapy" will be discussed in four broad historical-cultural divisions: preliterate cultures; early civilizations in Mesopotamia, Egypt, Israel; Greek Antiquity; Middle Ages, Renaissance, and Baroque. In reviewing "early music therapy" practice, from mostly unknown periods of early history (using preliterate cultures as a window) to increasingly better documented times, including preserved notation samples of actual "healing" music, five theories and applications of early music therapy can be differentiated. © 2015 Elsevier B.V.

  1. Émilie Du Châtelet's interpretation of the laws of motion in the light of 18th century mechanics.

    PubMed

    Reichenberger, Andrea

    2018-06-01

    Émilie Du Châtelet is well known for her French translation of Newton's Philosophiae Naturalis Principia Mathematica. It is the first and only French translation of Newton's magnum opus. The complete work appeared in 1759 under the title Principes mathématiques de la philosophie naturelle, par feue Madame la Marquise Du Chastellet. Before translating Newton's Principia, Du Châtelet worked on her Institutions de physique. In this book she defended the Leibnizian concept of living forces - vis viva. This paper argues that both of these works were part of a critical transformation and consolidation of post-Newtonian mechanics in the early 18th century, beyond Newton and Leibniz. This will be shown by comparing Du Châtelet's translation of Newton's axioms with her own formulations of the laws of motion in light of Thomas Le Seur's and François Jacquier's Geneva edition which holds a special place among the several editions of the Principia that appeared in the early 18th century.

    In this palaeobiological and palaeopathological study of skeletal remains, we attempt to define the physical characteristics, living conditions and the state of health of a small sample from two early Iron Age (IX-VIII century BC) graves at Capo Colonna, Trani (Bari, Apulia, southern Italy). In the thoraco-lumbar segment (T11-L1) of the vertebral column of an adult male 35 years old, we found wedge-shaped deformation of the anterior part of T12 with kyphosis of the affected tract. Digital radiography and volumetric reconstruction by 3D CT indicated that the alteration did not result from an infectious process (Pott's disease). Instead, it was a traumatic lesion probably caused by falling from a height. The archaeological investigation revealed extraordinary arrangements of the bodies in the graves: they were buried with a boulder placed on the coffin. This practice has been seen in similar graves in the Balkan area, particularly in Greece, from the Neolithic to the Early Middle Ages. The most likely explanation is a funeral ritual characterized by necrophobia, the purpose of which was to prevent the deceased from returning to terrorize the living.

Chlieh et al (2006) documented and modeled deformation of offshore islands associated with the 2004 rupture. Meltzner et al (2010) found coral evidence of uplifts in 1394±2 and 1450±3 CE. Sieh et al. (2015) documented associated tsunami that destroyed a structure built in 1366±3 CE, 40 km east of Banda Aceh at Lamreh. Since 2015, our landscape archaeology survey of 43 coastal villages over a 40-km reach of the coast has revealed 995 archaeological sites ranging from 10th century to present and containing over 5,000 carved gravestones and 50,000 ceramic sherds. The distribution of ceramic material suggests 7 discrete areas of cultural activity before the 1394 tsunami. Six of these appear to be villages that used imported ceramics and have been populated since the 10th century. However, detailed analysis indicates a clear reduction in activity between 1360 and 1450 CE. This suggests that one or both of the 1394 and 1450 tsunami disrupted the villages. The distribution of post-1500 CE ceramic material shows a gradual repopulation of pre-tsunami sites and a significant expansion of activity starting at the end of the 16th Century, for all areas except Lamreh. Only at on the elevated Lambaro highlands, above modern Lamreh, does material conclusively date between the 1394 and 1450 CE tsunamis. This historic trading site of "Lambri" contains large quantities of ceramics ranging from the early 11th century until the early 16th century, including precisely dated early-Ming (1403-1425 CE) material, some of which is distinctive imperial trade ceramics. We suspect that after the 1394 tsunami destroyed the other coastal settlements, the relatively safe highlands of Lambri were the only areas of the coast utilized for at least 50 years. After about 1450 CE, however, these highlands were abandoned, while the low-lying coastal communities began once again to

    The study of anatomy in England during the 18th and 19th century has become infamous for bodysnatching from graveyards to provide a sufficient supply of cadavers. However, recent discoveries have improved our understanding of how and why anatomy was studied during the enlightenment, and allow us to see the context in which dissection of the human body took place. Excavations of infirmary burial grounds and medical school cemeteries, study of hospital archives, and analysis of the content of surviving anatomical collections in medical museums enables us to re-evaluate the field from a fresh perspective. The pathway from a death in poverty, sale of the corpse to body dealer, dissection by anatomist or medical student, and either the disposal and burial of the remains or preservation of teaching specimens that survive today in medical museums is a complex and fascinating one.

    In a century of research published in the Journal of Applied Psychology , we have seen significant advances in our science. The results of this science have broad applications to the workplace and implications for improving organizational effectiveness through a variety of avenues. Research has focused on understanding constructs, relationships, and processes at multiple levels, including individual, team, and organizational. A plethora of research methods and questions have driven this work, resulting in a nuanced understanding of what matters in the workplace. In this paper, we synthesize the most salient discoveries, findings, and/or conclusions in 19 domains. We seek to summarize the progress that has been made and highlight the most salient directions for future work such that the next century of research in industrial and organizational psychological science can be as impactful as the first century has been.

    The field of paleoanthropology arose out of a strange and unacknowledged early phase of development prior to about the 1930s. It is often assumed that a key pillar of the discipline, the unity of humankind--the notion that humans are clearly separated phylogenetically (genealogically) from other non-human primates--was widely accepted from the inception of paleoanthropology around 1860. However, a final consensus on this fundamental question only appeared later on in the 20th century. This paper will focus on two key areas of disagreement, which reveal the unsettled state of this question during this early period: the question of uncertainty with respect to the number, identity and boundary of primate species (including humans) which prevailed in the 18th, 19th and early 20th centuries; and the matter of uncertainty with respect to the nature of the phylogenetic relationships among the various human populations and the other primate species which prevailed between 1864 and 1931. Consideration of these matters reveals that the modern research structure that paleoanthropologists take for granted today is much more recent than believed. Copyright © 2012 Elsevier Ltd.

    There is plenty of evidence for intensification of the global hydrological cycle. In Europe, the northern areas are predicted to receive more precipitation in the future and observational evidence suggests a parallel trend over the past decades. As a consequence, it would be essential to place the recent trend in precipitation in the context of proxy-based estimates of reconstructed precipitation variability over the past centuries. Tree rings are frequently used as proxy data for palaeoclimate reconstructions. Here we use deciduous ( Quercus robur) and coniferous ( Picea abies) tree-ring width chronologies from western Estonia to deduce past early-summer (June) precipitation variability since 1771. Statistical model transforming our tree-ring data into estimates of precipitation sums explains 42% of the variance in instrumental variability. Comparisons with products of gridded reconstructions of soil moisture and summer precipitation illustrate robust correlations with soil moisture (Palmer Drought Severity Index), but lowered correlation with summer precipitation estimates prior to mid-nineteenth century, these instabilities possibly reflecting the general uncertainties inherent to early meteorological and proxy data. Reconstructed precipitation variability was negatively correlated to the teleconnection indices of the North Atlantic Oscillation and the Scandinavia pattern, on annual to decadal and longer scales. These relationships demonstrate the positive precipitation anomalies to result from increase in zonal inflow and cyclonic activity, the negative anomalies being linked with the high pressure conditions enhanced during the atmospheric blocking episodes. Recently, the instrumental data have demonstrated a remarkable increase in summer (June) precipitation in the study region. Our tree-ring based reconstruction reproduces this trend in the context of precipitation history since eighteenth century and quantifies the unprecedented abundance of June

    Although some prodigies grow up to become creative masters as adults, there is no necessary link between early signs of talent and ultimate achievement. Four possible relations between early and late achievement are explored here. The analysis draws upon two lines of evidence: (1) a new theoretical approach that posits the existence of multiple intelligences and examines the important role of the domains and fields in which individuals work; (2) case studies of seven highly creative individuals who lived at the turn of the century. A strong contrast emerges between the adult creator, who must discover the domain in which he or she can excel and the child prodigy, who must invent a creative personality.

    The evolution of industrial-era warming across the continents and oceans provides a context for future climate change and is important for determining climate sensitivity and the processes that control regional warming. Here we use post-ad 1500 palaeoclimate records to show that sustained industrial-era warming of the tropical oceans first developed during the mid-nineteenth century and was nearly synchronous with Northern Hemisphere continental warming. The early onset of sustained, significant warming in palaeoclimate records and model simulations suggests that greenhouse forcing of industrial-era warming commenced as early as the mid-nineteenth century and included an enhanced equatorial ocean response mechanism. The development of Southern Hemisphere warming is delayed in reconstructions, but this apparent delay is not reproduced in climate simulations. Our findings imply that instrumental records are too short to comprehensively assess anthropogenic climate change and that, in some regions, about 180 years of industrial-era warming has already caused surface temperatures to emerge above pre-industrial values, even when taking natural variability into account.

    2014-10-01

    The aim of this paper is to present a short historical perspective on the neurophysiological approach to hysteria and conversion disorders. The body of this paper will be constituted of three main parts. In the first part, we will present the significant progress due to some pioneers of neurology/psychiatry during the XIXth century. As we shall see, this period was particularly rich in personalities whose work gradually laid the foundations to a true medical approach to hysteria. In the first half of the XXth century, different factors have led to a long eclipse of the neurological approach to hysteria. In the second part, we will show how, by the 1960's-1970's, the conceptual and methodological advances in neurophysiology, as well as the turning point of cognitive sciences (and cognitive psychology in particular) allowed a gradual reinstatement of hysteria within the fields of neurology and clinical neurophysiology. Finally, and this is the third part of this paper, we will show how over the past three decades, an entirely new neurophysiological approach to hysteria and conversion disorders has emerged.

    Suspicion towards technological advances has progressively grown during the xx(th) century. However, in the XXI(st) century, reading the NBIC (nanotechnology, biotechnology, information technology and cognitive science) report of the National Science Foundation, we can note that science has caught up with science fiction. These changes in public mentality on one side and in scientific capacities on the other argue for an evolution of the debate on sciences. The recent example of the national debate on nanotechnology in France has clearly shown that the public is no longer waiting for additional sources of scientific knowledge but rather waiting for the recognition of its authority to participate in the definition of the national R&D priority and associated scientific strategies. This is all the more legitimate that these strategies will have profound impact on the future of our societies and therefore cannot be decided only by scientists. Hence, it is crucial to identify innovative tools promoting debate on sciences and their technological spin-off. Here, we contend that science fiction has major assets that could face this challenge and facilitate the dialogue between sciences and society.

  14. Intersection of economics, history, and human biology: secular trends in stature in nineteenth-century Sioux Indians.

    Prince, J M

    1995-06-01

    An unusual confluence of historical factors may be responsible for nineteenth-century Sioux being able to sustain high statures despite enduring adverse conditions during the early reservation experience. An exceptionally long span of Dakota Sioux history was examined for secular trends using a cross-sectional design. Two primary sources were used: One anthropometric data set was collected in the late nineteenth century under the direction of Franz Boas, and another set was collected by James R. Walker in the early twentieth century. Collectively, the data represent the birth years between 1820 and 1880 for adult individuals 20 years old or older. Adult heights (n = 1197) were adjusted for aging effects and regressed on age, with each data set and each sex analyzed separately. Tests for differences between the adult means of age cohorts by decade of birth (1820-1880) were also carried out. Only one sample of adults showed any convincing secular trend (p < 0.05): surprisingly, a positive linear trend for Walker's sample of adult males. This sample was also the one sample of adults that showed significant differences between age cohorts. The failure to find any negative secular trend in this population of Amerindians is remarkable, given the drastic socioeconomic changes that occurred with the coming of the reservation period (ca. 1868). Comparisons with contemporary white Americans show that the Sioux remained consistently taller than whites well into the reservation period and that Sioux children (Prince 1989) continued to grow at highly favorable rates during this time of severe conditions. A possible explanation for these findings involves the relatively favorable level of subsistence support received by most of the Sioux from the US government, as stipulated by various treaties. Conservative estimates suggest that the Sioux may have been able to sustain net levels of per capita annual meat consumption that exceeded the US average for several years before 1893.

    Early detection and investigation of possible collisions and close approaches of asteroids with the Earth are necessary to exept the asteroid-comet hazard. The difficulty of prediction of close approaches and collisions associated with resonant returns after encounters with the Earth due to loss of precision in these encounters. The main research object is asteroid Apophis (99942), for which we found many possible orbits of impacts associated with resonant returns. It is shown that the early orbit change of Apophis allows to avoid main impacts, associated with resonant returns. Such a change of the orbit, in principle, is feasible. We also study the possible impacts with the Ground asteroid 2015 RN35. We present 21 possible collisions in this century, including 7 collisions with large gaps presented in NASA website. The results of observations by the telescope ZA-320M at Pulkovo Obser-vatory of the three near-Earth asteroids, namely, 7822, 20826, 68216, two of which 7822 and 68216 are potentially hazardous, are presented.

    Slackwater deposits are paleostage indicators in paleoflood hydrology that have commonly been used in numerous studies to estimate the magnitude and frequency of flood events and to reconstruct paleoenvironments and paleohydrology. In this study, individual flood events along the Pyeongchang (PC) and Dong (D) rivers of South Korea were differentiated on the basis of changes in deposit color, grain size, organic content, and the existence of laminations. Based on 137Cs and 14C chronological data, 19 flood events have occurred at site PC since 1720, while 17 flood events have occurred at site D since 1815. At the PC study site, the average time interval between the flood events is 15.4 years and the average sediment accumulation rate is 9.7 mm/y. At study site D, the average time interval is 15 years and the average sediment accumulation rate is 11.6 mm/y. These high sediment accumulation rates are consistent with those in humid areas (e.g., Japan) and explain how slackwater deposits can be preserved despite erosion, bioturbation, and pedogenic processes. Based on the results, the study area was divided into three periods: (1) a relatively wet period (1720-1810 CE), (2) a dry period (1810-1960 CE), and (3) a wet period (1960 CE-present). The flood time intervals and average sediment accumulation rates of the eighteenth century were shorter and higher than those of the nineteenth century. This suggests that on the Korean Peninsula, the paleoclimate of the Little Ice Age (LIA) was wetter than that from the nineteenth century to the early twentieth century.

    Records of double-flowered Silene dioica date from the late sixteenth century and four named varieties are grown today, as previously, for their horticultural interest. Although double-flowered mutants have been characterized in several plants, their study in dioecious species is of particular interest due to influences of the homeotic mutation on the different floral whorl configurations in males and females. We have analysed four double-flowered varieties of Silene dioica: Flore Pleno and Rosea Plena date back to the seventeenth and nineteenth centuries, Thelma Kay and Firefly were recognized in the latter part of the twentieth and early twenty-first centuries. We have analysed the floral structure of the four varieties, which have distinct floral architectures. Based on Y chromosome-specific PCR analysis we show that Firefly is male and that the other three varieties are female: Random Amplification of Polymorphic DNA (RAPD) analyses suggested a common origin for the three female varieties. The double-flowered phenotype in all four varieties is caused by mutation of the C-function MADS-box transcription factor gene SDM1. We show that Firefly carries a unique 44bp insertion into SDM1, revealing an independent origin for this variety. Comparative analysis of SDM1 cDNA and genomic sequences in Flore Pleno, Rosea Plena and Thelma Kay shows that all three are caused by the same 7bp insertion within SDM1 and therefore share a common origin. The three alleles also differ by several single nucleotide polymorphisms, which represent somatic mutations accumulated over four centuries of asexual propagation. PMID:25878355

  20. Constraining the temperature history of the past millennium using early instrumental observations

    NASA Astrophysics Data System (ADS)

    Brohan, P.

    2012-12-01

    The current assessment that twentieth-century global temperature change is unusual in the context of the last thousand years relies on estimates of temperature changes from natural proxies (tree-rings, ice-cores etc.) and climate model simulations. Confidence in such estimates is limited by difficulties in calibrating the proxies and systematic differences between proxy reconstructions and model simulations - notable differences include large differences in multi-decadal variability between proxy reconstructions, and big uncertainties in the effect of volcanic eruptions. Because the difference between the estimates extends into the relatively recent period of the early nineteenth century it is possible to compare them with a reliable instrumental estimate of the temperature change over that period, provided that enough early thermometer observations, covering a wide enough expanse of the world, can be collected. By constraining key aspects of the reconstructions and simulations, instrumental observations, inevitably from a limited period, can reduce reconstruction uncertainty throughout the millennium. A considerable quantity of early instrumental observations are preserved in the world's archives. One organisation which systematically made observations and collected the results was the English East-India Company (EEIC), and 900 log-books of EEIC ships containing daily instrumental measurements of temperature and pressure have been preserved in the British Library. Similar records from voyages of exploration and scientific investigation are preserved in published literature and the records in National Archives. Some of these records have been extracted and digitised, providing hundreds of thousands of new weather records offering an unprecedentedly detailed view of the weather and climate of the late eighteenth and early nineteenth centuries. The new thermometer observations demonstrate that the large-scale temperature response to the Tambora eruption and the 1809

    This anthropometric study focuses on the histories of three important Latin American countries - Brazil, Peru, and Argentina - during the 19th century, and tests hypotheses concerning their welfare trends. While non-farm Brazil and Lima, Peru, started at relatively low height levels, Brazil made substantial progress in nutritional levels from the 1860s to the 1880s. In contrast, Lima remained at low levels. Argentinean men were tall to begin with, but heights stagnated until 1910. The only exception were farmers and landowners, who benefited from the export boom.

  2. Accounts from 19th-century Canadian Arctic explorers' logs reflect present climate conditions

    NASA Astrophysics Data System (ADS)

    Overland, James E.; Wood, Kevin

    The widely perceived failure of 19th-century expeditions to find and transit the Northwest Passage in the Canadian Arctic is often attributed to extraordinary cold climatic conditions associated with the “Little Ice Age” evident in proxy records. However, examination of 44 explorers' logs for the western Arctic from 1818 to 1910 reveals that climate indicators such as navigability, the distribution and thickness of annual sea ice, monthly surface air temperature, and the onset of melt and freeze were within the present range of variability.The quest for the Northwest Passage through the Canadian archipelago during the 19th century is frequently seen as a vain and tragic failure. Polar exploration during the Victorian era seems to us today to have been a costly exercise in heroic futility, which in many respects it was. This perspective has been reinforced since the 1970s, when paleoclimate reconstructions based on Arctic ice core stratigraphy appeared to confirm the existence of exceptionally cold conditions consistent with the period glaciologists had termed the “Little Ice Age” (Figure 1a), with temperatures more than one standard deviation colder relative to an early 20th-century mean [Koerner, 1977; Koerner and Fisher, 1990; Overpeck et al., 1998]. In recent years, the view of the Little Ice Age as a synchronous worldwide and prolonged cold epoch that ended with modern warming has been questioned [Bradley and Jones, 1993; Jones and Briffa, 2001 ;Ogilvie, 2001].

    Palliative care went through a significant evolution in the 20th century, but the 19th century has been seen my some scholars as the real turning point toward the more modern concept of hospices and palliative care. To investigate some examples of earlier uses of the word 'palliative', a literature search was conducted within the earliest available BMJ archive sections, the years 1840 to 1842. This provided a glimpse into how the word was used in the medical literature in Victorian times, mid-nineteenth century. Search results brought up a number of case reports, and the word was employed to describe medicines ('use of palliatives') as well as passive, non-active treatment approaches, probably best described as a watch-and-wait strategy. Of note is that the first recorded use of the word in the archives is by a surgeon. Some doctors associated the word palliative with there not being any prospect for cure and only for the relief of symptoms and greater comfort of the patient. There were, however, early reflections on whether palliative treatments may in some cases increase the length of patients' lives.

  4. Historical mathematics in the French eighteenth century.

    PubMed

    Richards, Joan L

    2006-12-01

    At least since the seventeenth century, the strange combination of epistemological certainty and ontological power that characterizes mathematics has made it a major focus of philosophical, social, and cultural negotiation. In the eighteenth century, all of these factors were at play as mathematical thinkers struggled to assimilate and extend the analysis they had inherited from the seventeenth century. A combination of educational convictions and historical assumptions supported a humanistic mathematics essentially defined by its flexibility and breadth. This mathematics was an expression of l'esprit humain, which was unfolding in a progressive historical narrative. The French Revolution dramatically altered the historical and educational landscapes that had supported this eighteenth-century approach, and within thirty years Augustin Louis Cauchy had radically reconceptualized and restructured mathematics to be rigorous rather than narrative.

    The authors simulate transient twentieth-century climate in the Goddard Institute for Space Studies (GISS) GCM, with aerosol and ozone chemistry fully coupled to one another and to climate including a full dynamic ocean. Aerosols include sulfate, black carbon (BC), organic carbon, nitrate, sea salt, and dust. Direct and BC snow-albedo radiative effects are included. Model BC and sulfur trends agree fairly well with records from Greenland and European ice cores and with sulfur deposition in North America; however, the model underestimates the sulfur decline at the end of the century in Greenland. Global BC effects peak early in the century (1940s); afterward the BC effects decrease at high latitudes of the Northern Hemisphere but continue to increase at lower latitudes. The largest increase in aerosol optical depth occurs in the middle of the century (1940s-80s) when sulfate forcing peaks and causes global dimming. After this, aerosols decrease in eastern North America and northern Eurasia leading to regional positive forcing changes and brightening. These surface forcing changes have the correct trend but are too weak. Over the century, the net aerosol direct effect is -0.41 Watts per square meter, the BC-albedo effect is -0.02 Watts per square meter, and the net ozone forcing is +0.24 Watts per square meter. The model polar stratospheric ozone depletion develops, beginning in the 1970s. Concurrently, the sea salt load and negative radiative flux increase over the oceans around Antarctica. Net warming over the century is modeled fairly well; however, the model fails to capture the dynamics of the observedmidcentury cooling followed by the late century warming.Over the century, 20% of Arctic warming and snow ice cover loss is attributed to the BC albedo effect. However, the decrease in this effect at the end of the century contributes to Arctic cooling. To test the climate responses to sulfate and BC pollution, two experiments were branched from 1970 that removed

    Selfie-photography is generally thought of as a cultural mass phenomenon of the early 21st century, inseparably related to the development and triumph of the smartphone with integrated camera. Western culture, however, has been highly familiar with self-depictions since the Renaissance days. Putting the contemporary selfie into this historic context covering more than five centuries of cultural development from Dürer's (1500) famous “Self-Portrait at 28” (also known as “Selbstbildnis im Pelzrock”) to today's Instagram galleries allows for identifying central parallels concerning the technical and social antecedents as well as common underlying psychological factors and shared properties of different kinds of self-depiction. The article provides an overview of the types of contemporary photographic selfies and compares them with painted self-portraits. Finally, this historic perspective leads us to the insight that self-portraits as well as selfies are both referring to nothing less than the “conditio humana.” PMID:28270789

  7. Growing a Colony from an Outpost - The Colonization of Mars in the Twenty-Second Century

    NASA Astrophysics Data System (ADS)

    Halyard, R. J.

    Near the end of the Twenty-first Century there may be one or more permanent outposts on Mars; these outposts will recycle their water and atmosphere and remain permanently staffed. The Earth will provide crew rotation plus food supplies and replacement equipment approximately every one and one-half years. Assuming that the permanent outposts are located near deposits of frozen water and necessary minerals, the potential exists of expanding these outposts to a small, self-sufficient colony. Additional equipment, structures and personnel plus changes in operations will be required to make the expansion to a colony possible. Because many variables and assumptions exist in the determination of the additional hardware, the resulting proposed colony design is very tentative and provides only as an initial estimate of the effort required. However if the assumptions are met and the equipment indicated developed, it should definitely be possible to establish a Mars colony in the early Twenty-second Century.

    The present work is a review of the remedies in use in Ferrara against tuberculosis in the 1800s. The work started from the discovery of accounts describing methods and remedies. These remedies were also in use world wide. Of particular interest is the work by Antonio Campana, a famous professor of Pharmaceutical Chemistry and Botany in Ferrara, who wrote a pharmacopoeia which had several editions between 1797 and 1841. The Farmacopea Ferrarese was addressed to the apothecaries of Ferrara. Nevertheless, due to its great reputation it had an international distribution. It provided us with an exhaustive view about the medical field in Ferrara in the early 1800s. The remedies adopted in the city in the second half of the century were in line with those present abroad. The work was also supported by the discovery of statistical accounts of the Sant'Anna hospital from 1871. The manuscript written by Alessandro Bennati enabled elucidation of the methods used to treat tuberculosis in the second half of the century. Bennati's work is an historical document completed by the work of the physician Cesare Minerbi.

    Toward the end of the twentieth century, it became evident to professionals working within the meterological arena that the world's climate system was showing signs of change that could not be adequately explained in terms of natural variation. Since that time there has been an increasing recognition that the climate system is changing as a result of human industries and lifestyles, and that the outcomes may prove catastrophic to the world's escalating population. Compiled by an international team formed under the auspices of the World Meteorological Organization (WMO), Climate: Into the 21st Century features an unrivalled collection of essays by the world's leading meteorological experts. These fully integrated contributions provide a perspective of the global climate system across the twentieth century, and describe some of the most arresting and extreme climatic events and their effects that have occurred during that time. In addition, the book traces the development of our capabilities to observe and monitor the climate system, and outlines our understanding of the predictability of climate on time-scales of months and longer. It concludes with a summary of the prospects for applying the twentieth century climate experience in order to benefit society in the twenty-first century. Lavishly illustrated in color, Climate is an accessible acccount of the challenges that climate poses at the start of the twenty-first century. Filled with fascinating facts and diagrams, it is written for a wide audience and will captivate the general reader interested in climate issues, and will be a valuable teaching resource. William Burroughs is a successful science author of books on climate, including Weather (Time Life, 2000), and Climate Change: A Multidisciplinary Approach (2001), Does the Weather Really Matter? (1997) and The Climate Revealed (1999), all published by Cambridge University Press.

    Lanuza Navarro, Tayra M C

    2006-01-01

    It is well known that astrological practice during the Early Modern period was closely related to medicine, and that it provided a tool for diagnosis and treatments. An interesting aspect of this relationship of medicine and astrology is the recognition of the prevailing ideas about medical astrology in the astrological works and astrological-medical treatises. This article discusses the ideas of Galenism and the astrological doctrines that established such a strong relationship between astrology and medicine. There is an overview of the Spanish authors who wrote about the subject, especially those linked with the universities. The paper then goes into detail about the examples of these ideas found in the Spanish printed texts of the seventeenth century. Finally, there is a section on some very interesting and little known treatises on medical astrology which were a reference for the practice of astrological medicine in the period.

  12. Rainfall over the African continent from the 19th through the 21st century

    Most of the African continent is semi-arid and hence prone to extreme variations in rainfall from year to year. The extreme droughts that have plagued the Sahel and eastern Africa are particularly well known. This article uses a markedly expanded and updated rainfall data set to examine rainfall variability in 13 sectors that cover most of the continent. Annual rainfall is presented for each sector; the March-to-May and October-November seasons are also examined for equatorial sectors. In each case, the article includes the longest and most comprehensive precipitation gauge series ever published. All time series cover at least a century and most cover roughly one and one-half centuries or more. Although towards the end of the 20th century there was a widespread trend towards more arid conditions, few significant trends are evident over the entire period of record. The largest were downward trends in the Sahel and western sectors of North Africa. In those regions, an abrupt reduction in rainfall occurred around 1968, but a synchronous change occurred many other parts of Africa. A recovery did occur in the Sahel, but to varying degrees across the east-west expanse of the region. Noteworthy is that the west-to-east rainfall gradient across the region appears to have weakened in recent decades. For the continent as a whole, another change began in the 1980s decade, with more arid conditions persisting at the continental scale until early in the twenty-first century. No other such period of dry conditions occurred within the roughly one and one-half centuries evaluated here. A notable change also occurred at the seasonal level. During the period 1980 to 1998 rainfall during March-to-May was well below the long-term mean throughout most of the area from 20° N to 35° S. At the same time rainfall was above the long-term mean in most of eastern sectors within this latitude span, indicating a change in the seasonality of rainfall of a large part of Africa.

  13. "The History of Half the Sex": Fashionable Disease, Capitalism, and Gender in the Long Eighteenth Century.

    PubMed

    Lawlor, Clark

    This essay examines the way in which disease was framed and narrated as fashionable in the long eighteenth century, and argues that the intensifying focus on women's fashionable disorders in the period grew in tandem with the rise of an unstable capitalism in its manifold forms. Using the satirical articles written by Henry Southern in the London Magazine-"On Fashions" (August 1825), "On Fashions in Physic" (October 1825), and "On Dilettante Physic" (January 1826)-and the literature that led to them, I analyze the role that women were now taking in the newly capitalized world of the early nineteenth century. This world was characterized by a burgeoning medical market, a periodical and print market which could adequately reflect and promote fashionable diseases and the medical market that spawned them, and the nexus of actors in the whole drama of the production, maintenance, and dissolution of fashionable diseases.

    This paper uses a combination of Geographic Information Systems (GIS) and corpus linguistic analysis to extract and analyse disease related keywords from the Registrar-General's Decennial Supplements. Combined with known mortality figures, this provides, for the first time, a spatial picture of the relationship between the Registrar-General's discussion of disease and deaths in England and Wales in the nineteenth and early twentieth centuries. Techniques such as collocation, density analysis, the Hierarchical Regional Settlement matrix and regression analysis are employed to extract and analyse the data resulting in new insight into the relationship between the Registrar-General's published texts and the changing mortality patterns during this time.

    2010-01-01

    Within the discipline of psychology, the conventional history outlines the development of two fundamental approaches to the scientific study of emotion—“basic emotion” and “appraisal” traditions. In this article, we outline the development of a third approach to emotion that exists in the psychological literature—the “psychological constructionist” tradition. In the process, we discuss a number of works that have virtually disappeared from the citation trail in psychological discussions of emotion. We also correct some misconceptions about early sources, such as work by Darwin and James. Taken together, these three contributions make for a fuller and more accurate account of ideas about emotion during the century stretching from 1855 to just before 1960. PMID:20221412

    Gaspare Tagliacozzi published his carefully documented procedures for nasal reconstruction at the end of the sixteenth century. However, almost all authorities in the succeeding century failed to give him credence. Although his name was widely known, his work became an object of scorn. James Cooke, author of one of the most popular English surgical textbooks of the seventeenth century, in an amusing and previously unnoted reference, adds to this denigration and helps to explain why nasal reconstruction became a subject of satire in England.

  19. Prevention of asthma: where are we in the 21st century?

    PubMed

    Propp, Phaedra; Becker, Allan

    2013-12-01

    Asthma is the most common chronic disease of childhood and, in the latter part of the 20th century, reached epidemic proportions. Asthma is generally believed to result from gene-environment interactions. There is consensus that a 'window of opportunity' exists during pregnancy and early in life when environmental factors may influence its development. We review multiple environmental, biologic and sociologic factors that may be important in the development of asthma. Meta-analyses of studies have demonstrated that multifaceted interventions are required in order to develop asthma prevention. Multifaceted allergen reduction studies have shown clinical benefits. Asthma represents a dysfunctional interaction with our genes and the environment to which they are exposed, especially in fetal and early infant life. The increasing prevalence of asthma also may be an indication of increased population risk for the development of other chronic non-communicable autoimmune diseases. This review will focus on the factors which may be important in the primary prevention of asthma. Better understanding of the complex gene-environment interactions involved in the development of asthma will provide insight into personalized interventions for asthma prevention.

  20. An Eight-Century High-Resolution Paleoclimate Record From the Cariaco Basin: Baseline Variability and the 20th Century

    The Cariaco Basin, Venezuela is well-positioned to record a detailed history of surface ocean changes along the southern margin of the Caribbean and the tropical Atlantic. Varved, high deposition rate sediments deposited under anoxic conditions and an abundance of well-preserved microfossils result in one of the few marine records capable of preserving evidence of interannual- to decadal-scale climate variability in the tropical Atlantic. Here we present Mg/Ca and stable oxygen isotope data with sub-decadal resolution derived from sediments deposited over the last 800 years. Mg/Ca measured on the planktic foraminifer Globigerina bulloides from a Cariaco Basin sediment core strongly correlates with spring (March-May) instrumental SSTs between AD 1870 and 1990. The long-term record displays a surprising amount of variability for a tropical location. The temperature swings are not necessarily related to local upwelling variability, but instead represent wider conditions in the Caribbean and western tropical Atlantic. The Mg/Ca-SST record also captures the decadal and multidecadal variability observed in global land and sea surface temperature anomalies, and correlates with Atlantic tropical storm and hurricane frequency over the late-19th and 20th centuries. On average, 20th century temperatures are not the warmest in the entire record, but they do show the largest increase in magnitude and fastest rate of SST change over the last eight hundred years. Stable oxygen isotope data also correlate well with instrumental SSTs, but not over the full instrumental record. Poor correlations with early instrumental SST data suggest a salinity overprint. However, reconstructing δ- water variability using combined Mg/Ca and δ18O data is not straightforward as the δ- water/salinity relationship varies seasonally in the Cariaco Basin. Comparisons with percent titanium data suggest intervals of both local and regional surface salinity changes over the length of the record.

    One of the most important issues in national urban planning is arrangement of high-rise buildings in the largest cities of Russia. This issue becomes especially acute in such cities as Saint Petersburg, which has unique architectural and urban-planning heritage preserved to a great extent. In this regard, it seems important to trace the evolution of high-rise construction development and arrangement in Leningrad - Saint Petersburg in the middle of the 20th — early 21st centuries. The goal of the article is to consider high-rise construction development regarding both public and residential buildings in comparison of project ideas and results of their implementation in the 1940s-2000s. Prerequisites and issues of high-rise construction of that period are considered. Particular attention is paid to changes in the official urban-planning policy, regulatory framework and attitude of city authorities to high-rise construction. The study was carried out with the consideration of the following historic periods differing in their urban-planning policy: the late 1940s-1950s; 1960s; 1970-1980s; 1990s; 2000s-2010s. Economical prerequisites of high-rise construction and their influence on the modern urban-planning policy during the post-Soviet period are considered. In conclusion, an attempt is made to determine tendencies of high-rise construction development in Saint Petersburg.

Dimitrie Onciul 23e25, Sector 2, 024053 Bucharest, Romania Razelm-Sinoe Lagoon System, situated in the NW part of the Black Sea, in tight connection with the Danube Delta, has been subject to major changes due to human interventions in the past century. These changes have resulted into a complete change of the Lagoon specific ecosystems compared to its pristine state. In its natural state, as brackish - transitional environment, Antipa (1894) mentions Razelm Lagoon as one of the places with the greatest fisheries around the Black Sea coast (about 1879 - 1884, there were approximately 10,000 fishermen, all working on the Razelm Sinoe Lagoon System). Starting with the end of the XIXth Century, new canals were dug and existing channels were dredged in order to develop tighter connections with the Danube River. The natural inlet of Portita was blocked four decades ago and connections between the various parts of the lagoon system were controlled by the building of locks and sluices. The 2 inlets of Sinoe Lagoon were also controlled during early 1980s. Under these conditions, the lagoon ecosystem changed from brackish towards freshwater, with major effects on the existing flora and fauna. The period of brutal interventions ended in 1989 and the Razelm-Sinoe Lagoon System became part of the Danube Delta Biosphere Reserve in 1991, with a strict policy of nature protection and restoration. Spatial planning has been the major management option for the entire reserve, lagoon system included. Plans for sustainable development of the Razelm-Sinoe Lagoon System have been built in a participative manner, involving the local stakeholders, as part of FP7 ARCH project. Special attention has been given to impacts of climate change. The study presents the vision for the development Razelm-Sinoe Lagoon System over

    The current assessment that twentieth-century global temperature change is unusual in the context of the last thousand years relies on estimates of temperature changes from natural proxies (tree-rings, ice-cores etc.) and climate model simulations. Confidence in such estimates is limited by difficulties in calibrating the proxies and systematic differences between proxy reconstructions and model simulations. As the difference between the estimates extends into the relatively recent period of the early nineteenth century it is possible to compare them with a reliable instrumental estimate of the temperature change over that period, provided that enough early thermometer observations, covering a wide enough expanse of the world, can be collected. One organisation which systematically made observations and collected the results was the English East-India Company (EEIC), and their archives have been preserved in the British Library. Inspection of those archives revealed 900 log-books of EEIC ships containing daily instrumental measurements of temperature and pressure, and subjective estimates of wind speed and direction, from voyages across the Atlantic and Indian Oceans between 1789 and 1834. Those records have been extracted and digitised, providing 273 000 new weather records offering an unprecedentedly detailed view of the weather and climate of the late eighteenth and early nineteenth centuries. The new thermometer observations demonstrate that the large-scale temperature response to the Tambora eruption and the 1809 eruption was modest (perhaps 0.5 °C). This provides a powerful out-of-sample validation for the proxy reconstructions - supporting their use for longer-term climate reconstructions. However, some of the climate model simulations in the CMIP5 ensemble show much larger volcanic effects than this - such simulations are unlikely to be accurate in this respect.

  5. The Live Chicken Treatment for Buboes: Trying a Plague Cure in Medieval and Early Modern Europe.

    PubMed

    Heinrichs, Erik A

    2017-01-01

    This article traces a seven-hundred-year history of one puzzling treatment for plague buboes that used the rumps of chickens to draw out the bubo's poisons. It traces the origin of the recipe to Avicenna's Canon and explores how medieval and early modern physicians altered the treatment and explained its workings up to the early eighteenth century. Much of the analysis focuses on the variants of the recipe that German physicians created as they adapted or elaborated on older recipes. This article argues that most variations of the treatment likely resulted from physicians trying ideas on paper, rather than in practice, as they attempted to unlock the mysteries of the plague's underlying poisons. Starting in the sixteenth century, however, evidence suggests that practice began to play an important role in the adaptation and interpretation of the "live chicken" recipes.

  9. The early history of the placebo.

    PubMed

    Jütte, Robert

    2013-04-01

    In the late 18th century the term "placebo" became part of medical jargon. In contrast to the prevailing opinion that it was the Scottish physician and pharmacologist William Cullen (1710-1790) who introduced this expression into medical language in 1772, the credit must be given to another English physician, Alexander Sutherland (born before 1730 - died after 1773). The main reason for administering placebos in late 18th-century medical practice was to satisfy the patient's demand and his expectations. Another reason was obstinancy of the patient: the motivation behind such prescriptions may be summarized as prescribing inert drugs for the satisfaction of the patient's mind, and not with the view of producing any direct remedial effect. In most cases these 18th century physicians did not administer "pure" placebos but resorted to any kind of medicine which they thought simple, feeble, or altogether powerless, non-perturbing medicines. Today we make the distinction between pure placebos (substances with no pharmacological effect, e.g. sugar pills) and impure placebos (substances with pharmacological effect but not on the condition being treated). In the 18th century those physicians who prescribed placebo usually thought of drugs which were considered not very effective in the particular case, e.g. a mild ointment. At the same time, only very few brilliant minds came up with the ingenious idea of using inert substances as placebo. An alternative to milk sugar used as placebo in homeopathy was breadpills. Recent research suggests that expectancy is an integral part of the placebo effect. As early as 1775 the English bishop John Douglas (1721-1807) anticipated the findings of modern research on the placebo effect. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The Syenite from the Cervo Torrent Valley near Biella in northern Italy has been widely used as a building material. During the XXth century it has been exported all over the World for covering and paving slabs and monumental work. It is an intrusive magmatic rock found in the Cervo Valley pluton, which is part of the Balma pluton. It formed about 30 million years ago as a result of the Alpine Orogeny and is known to be post-orogenic because of the absence of metamorphism. Hydrothermal mineralization associated with the pluton includes minerals of molybdenum, tungsten, copper, lead, silver and gold. Utilisation of the Syenite has been the only industrial activity in the high Cervo Valley sustaining the whole of valley life. During the second half of the XIXth century and during the first part of the XXth the competencies and the working skills of the Cervo Valley stonecutters was exported as far as Perù and China. It was e.g. used for the edification and refinement of the Oropa Sanctuary square in Piedmont, Italy. It has been recognized as an interesting building material because of the intrinsic characteristics such as its resistance to mechanical wear, durability of colour tone and intensity and resistance to water wear (e.g. in fountains) and maintains its mechanical integrity over time. Diorite is also a magmatic intrusive rock and, similar to the syenite, differs from granite due to the low concentration of quartz (<10%). It consists of plagioclase, pyroxene, amphibole and quartz. It is exploited at the Vico Canavese quarry, near Turin, Italy. It is easy to cut and to process with the suitable tools. It has a number of variants, each with specific characteristics and behavior. It is multipurpose material and consequently it can be used in different shape and application, such as slabs, covering, bed river, building block and tiles. Although mainly used in Italy, it has also been used world wide for many different constructional and aesthetic purposes. These

    The global importance of food safety is not fully appreciated by many public health authorities despite a constant increase in the prevalence of foodborne illness. Numerous devastating outbreaks of salmonellosis, cholera, enterohaemorrhagic Escherichia coli infections, hepatitis A and other diseases have occurred in both industrialized and developing countries. In addition, many of the re-emerging or newly recognized pathogens are foodborne or have the potential of being transmitted by food and/or drinking water. More foodborne pathogens can be expected because of changing production methods, processes, practices and habits. During the early 21st century, foodborne diseases can be expected to increase, especially in developing countries, in part because of environmental and demographic changes. These vary from climatic changes, changes in microbial and other ecological systems, to decreasing freshwater supplies. However, an even greater challenge to food safety will come from changes resulting directly in degradation of sanitation and the immediate human environment. These include the increased age of human populations, unplanned urbanization and migration and mass production of food due to population growth and changed food habits. Mass tourism and the huge international trade in food and feed is causing food and feedborne pathogens to spread transnationally. As new toxic agents are identified and new toxic effects recognized, the health and trade consequences of toxic chemicals in food will also have global implications. Meeting the huge challenge of food safety in the 21st century will require the application of new methods to identify, monitor and assess foodborne hazards. Both traditional and new technologies for assuring food safety should be improved and fully exploited. This needs to be done through legislative measures where suitable, but with much greater reliance on voluntary compliance and education of consumers and professional food handlers. This will

  16. A Coupled Ocean-Iceberg Model Over The 20th Century: Iceberg Flux At 48°N As A Proxy For Greenland Iceberg Discharge

    NASA Astrophysics Data System (ADS)

    Bigg, G. R.; Wilton, D.; Hanna, E.

    2013-12-01

    Grant R. Bigg1 , David J. Wilton1 and Edward Hanna1 1Department of Geography, The University of Sheffield, Sheffield, S10 2TN We have used a coupled ocean-iceberg model, the Fine Resolution Greenland and Labrador ocean model [1], to study the variation in, and trajectory of, icebergs over the twentieth century, focusing particularly on Greenland and surrounding areas. The model is forced with daily heat, freshwater and wind fluxes derived from the Twentieth Century Reanalysis Project [2]. We use the observed iceberg flux at 48°N off Newfoundland (I48N) from 1900 to 2008 [3] to assess the iceberg component of the model. Model I48N is calculated with both a variable and constant annual calving rate. The results show that ocean and atmosphere changes alone do not account for the variation in observed I48N and suggests that this series can be used as a proxy for iceberg discharge from west Greenland tidewater glaciers. The implication of this proxy is that there is significant interannual variability in Greenland iceberg discharge over the whole twentieth century. Our model results suggest that in the early decades of the twentieth century I48N was dominated by icebergs originating from south Greenland (below latitude 65°N) with west Greenland becoming the main source of I48N from the late 1930s onwards. Modeled icebergs from the east of Greenland very rarely reach 48°N. We also present results from the ocean model showing the variation of ocean transport fluxes over the course of the twentieth and early twenty first century. References 1. M. R. Wadley, and G. R.

    Fire is a global phenomenon and tightly interacts with the biosphere and climate. This study provides the first quantitative assessment of fire’s influence on the global land air temperature during the 20th century through its impact on terrestrial ecosystems. We quantify the impact of fire by comparing 20th century fire-on and fire-off simulations with the Community Earth System Model (CESM) as the model platform. Here, results show that fire-induced changes in terrestrial ecosystems increased global land surface air temperature by 0.04 °C. Such changes significantly warmed the tropical savannas and southern Asia mainly by reducing latent heat flux, but cooledmore » Southeast China by enhancing the East Asian winter monsoon. 20% of the early 20th century global land warming can be attributed to fire-induced changes in terrestrial ecosystems, providing a new mechanism for explaining the poorly-understood climate change.« less

    Pine Island Glacier, a major outlet of the West Antarctic Ice Sheet, has been undergoing rapid thinning and retreat for the past two decades. We demonstrate, using glacial-geological and geochronological data, that Pine Island Glacier (PIG) also experienced rapid thinning during the early Holocene, around 8000 years ago. Cosmogenic (10)Be concentrations in glacially transported rocks show that this thinning was sustained for decades to centuries at an average rate of more than 100 centimeters per year, which is comparable with contemporary thinning rates. The most likely mechanism was a reduction in ice shelf buttressing. Our findings reveal that PIG has experienced rapid thinning at least once in the past and that, once set in motion, rapid ice sheet changes in this region can persist for centuries.
