  2. External forcing of the early 20th century Arctic warming

    2013-12-01

    Full Text Available The observed Arctic warming during the early 20th century was comparable to present-day warming in terms of magnitude. The causes and mechanisms for the early 20th century Arctic warming are less clear and need to be better understood when considering projections of future climate change in the Arctic. The simulations using the Bergen Climate Model (BCM can reproduce the surface air temperature (SAT fluctuations in the Arctic during the 20th century reasonably well. The results presented here, based on the model simulations and observations, indicate that intensified solar radiation and a lull in volcanic activity during the 1920s–1950s can explain much of the early 20th century Arctic warming. The anthropogenic forcing could play a role in getting the timing of the peak warming correct. According to the model the local solar irradiation changes play a crucial role in driving the Arctic early 20th century warming. The SAT co-varied closely with local solar irradiation changes when natural external forcings are included in the model either alone or in combination with anthropogenic external forcings. The increased Barents Sea warm inflow and the anomalous atmosphere circulation patterns in the northern Europe and north Atlantic can also contribute to the warming. In summary, the early 20th century warming was largely externally forced.

    During the 1800’s – before the well-known genocide, planned in the twentieth century – there were massacres and persecution on Armenian villages. It is important to underline that many Christian Armenians lived in Ottoman Empire. At the beginning of 1800’s they paid many taxes and felt themselves an important part of the Empire. Thus they would have liked to achieve more significant public roles, without losing their religion and cultural background. Howewer, the Turkish leaders and populatio...

    The last one hundred years have seen many important achievements in the classical part of number theory. After the proof of the Prime Number Theorem in 1896, a quick development of analytical tools led to the invention of various new methods, like Brun's sieve method and the circle method of Hardy, Littlewood and Ramanujan; developments in topics such as prime and additive number theory, and the solution of Fermat's problem. "Rational Number Theory in the 20th Century: From PNT to FLT" offers a short survey of 20th century developments in classical number theory, documenting between

  5. Marl Prairie Vegetation Response to 20th Century Hydrologic Change

    2007-01-01

    We conducted geochronologic and pollen analyses from sediment cores collected in solution holes within marl prairies of Big Cypress National Preserve to reconstruct vegetation patterns of the last few centuries and evaluate the stability and longevity of marl prairies within the greater Everglades ecosystem. Based on radiocarbon dating and pollen biostratigraphy, these cores contain sediments deposited during the last ~300 years and provide evidence for plant community composition before and after 20th century water management practices altered flow patterns throughout the Everglades. Pollen evidence indicates that pre-20th century vegetation at the sites consisted of sawgrass marshes in a peat-accumulating environment; these assemblages indicate moderate hydroperiods and water depths, comparable to those in modern sawgrass marshes of Everglades National Park. During the 20th century, vegetation changed to grass-dominated marl prairies, and calcitic sediments were deposited, indicating shortening of hydroperiods and occurrence of extended dry periods at the site. These data suggest that the presence of marl prairies at these sites is a 20th century phenomenon, resulting from hydrologic changes associated with water management practices.

    2011-01-01

    Weyl's original scale geometry of 1918 ("purely infinitesimal geometry") was withdrawn from physical theory in the early 1920s. It had a comeback in the last third of the 20th century in different contexts: scalar tensor theories of gravity, foundations of physics (gravity, quantum mechanics), elementary particle physics, and cosmology. Here we survey the last two segments. It seems that Weyl geometry continues to have an open research potential for the foundations of physics after the turn of the century.

  13. Immigration and Crime in Early 20th Century America

    MOEHLING, CAROLYN; Piehl, Anne Morrison

    2007-01-01

    Research on crime in the late 20th century has consistently shown that immigrants have lower rates of involvement in criminal activity than natives. We find that a century ago immigrants may have been slightly more likely than natives to be involved in crime. In 1904 prison commitment rates for more serious crimes were quite similar by nativity for all ages except ages 18 and 19 when the commitment rate for immigrants was higher than for the native born. By 1930, immigrants were less likely t...

  14. The epidemic of the 20(th) century: coronary heart disease.

    2014-09-01

    Heart disease was an uncommon cause of death in the US at the beginning of the 20th century. By mid-century it had become the commonest cause. After peaking in the mid-1960s, the number of heart disease deaths began a marked decline that has persisted to the present. The increase in heart disease deaths from the early 20th century until the 1960s was due to an increase in the prevalence of coronary atherosclerosis with resultant coronary heart disease, as documented by autopsy studies. This increase was associated with an increase in smoking and dietary changes leading to an increase in serum cholesterol levels. In addition, the ability to diagnose acute myocardial infarction with the aid of the electrocardiogram increased the recognition of coronary heart disease before death. The substantial decrease in coronary heart disease deaths after the mid-1960s is best explained by the decreased incidence, and case fatality rate, of acute myocardial infarction and a decrease in out-of-hospital sudden coronary heart disease deaths. These decreases are very likely explained by a decrease in coronary atherosclerosis due to primary prevention, and a decrease in the progression of nonobstructive coronary atherosclerosis to obstructive coronary heart disease due to efforts of primary and secondary prevention. In addition, more effective treatment of patients hospitalized with acute myocardial infarction has led to a substantial decrease in deaths due to acute myocardial infarction. It is very likely that the 20th century was the only century in which heart disease was the most common cause of death in America.

    In the first half of the 20th century G. W. Stewart was a physics faculty member at the University of Iowa (UI) with a distinguished record of research and teaching, especially in acoustics. Much of his research focused on the design and use of several types of acoustical filters. Some apparatus which he developed or utilized are still housed in the Department of Physics and Astronomy or are available in detailed diagrams. Demonstration apparatus (apparently homemade) from his era are still available for use. Carl E. Seashore, a renowned psychologist also at UI in the early 20th century, had interdisciplinary interests linking psychology, speech and hearing, music, and acoustics. He was responsible for obtaining an Henrici harmonic analyzer, a mechanical Fourier analyzer manufactured in Switzerland, a special grant from the state legislature during Depression conditions provided the funding. It resides in the Department of Speech Pathology and Audiology at UI. The Grinnell College Physics Historical Museum houses a set of 18 Helmholtz resonators and a Savart bell and resonator. Apparatus at Iowa State University, the University of Northern Iowa, and other Iowa institutions will also be described. Pictures and diagrams as well as some actual apparatus will be exhibited.

    Physics students often have problems understanding waves. Over the years numerous mechanical devices have been devised to show the propagation of both transverse and longitudinal waves (Ref. 1). In this article an updated version of an early-20th-century transverse wave machine is discussed. The original, Fig. 1, is at Creighton University in Omaha, NE. The new version, by the authors, is shown in Fig. 2. It was designed in such a way that it can be built relatively easily. Sliders that rest on a rotating helical rail move up and down in approximate simple harmonic motion. When the helix is at rest, the tops of the sliders form a good approximation to a sine wave. In the original, the sliders are double-ended knitting needles, and the handle was taken from an earlier piece of apparatus.

  18. Essential shift: Scientific revolution in the 20th century

    Ismay, David K.

    1993-05-01

    With the publishing of Sir Isaac Newton's Principia Mathematica in 1687, a scientific paradigm was established that clearly dominated society for two and half centuries. Many historians of science have identified the Copenhagen interpretation of the quantum theory, formulated c.1927, as having completed a scientific revolution that ended the reign of classical Newtonian science. A rival claim to contemporary scientific revolution, however, has been put forward by Ilya Prigogine and the Brussels school of thermodynamics based on Prigogine's work in non-equilibrium thermodynamics. Using the historical consensus model of scientific revolution first articulated by Thomas S. Kuhn in 1962, this analysis examines the extent to which the Copenhagen interpretation of the quantum theory and the work of IIya Prigogine complete the conceptual, scientific paradigm-shift necessary for a scientific revolution. The resulting historical evidence shows that the Copenhagen interpretation did not complete a paradigm-shift; instead, it was a self-revelation by the scientific community which revealed the essence and fundamental limitations of Newtonian science. Evidence further indicates that the valid claim to scientific revolution in the 20th century lies with the contemporary work of Prigogine and the Brussels school. By abandoning the deterministic, mechanical world-view of the Newtonian paradigm and accepting a new reality of process and irreversible time, Prigogine and his associates have established the foundations for a revolutionary new scientific paradigm.

    2015-12-01

    Area changes of photospheric faculae associated with magnetic active regions are responsible for the bright contribution to variation in total solar irradiance (TSI). Yet, the 102-year white light (WL) facular record measured by the Royal Greenwich Observatory between 1874 and 1976 has been largely overlooked in past TSI reconstructions. We show that it may offer a better measure of the brightening than presently used chromospheric proxies or the sunspot number. These are, to varying degrees, based on magnetic structures that are dark at the photosphere even near the limb. The increased contribution of the dark component to these proxies at high activity leads to an overestimate of solar brightening around peaks of the large spot cycles 18 and 19. The WL facular areas measure only the bright contribution. Our reconstruction based on these facular areas indicates that TSI decreased by about 0.1% during these two cycles to a 20th century minimum, rather than brightening to some of the highest TSI levels in four centuries, as reported in previous reconstructions. This TSI decrease may have contributed more to climate cooling between the 1940s and 1960s than present modeling indicates. Our finding adds to previous evidence that such suppression of solar brightening by an increased area of dark flux tubes might explain why the Sun is anomalously quiet photometrically compared to other late-type stars. Our findings do not change the evidence against solar driving of climate warming since the 1970s.

  1. Everglades Plant Community Response to 20th Century Hydrologic Changes

    Pollen records in sediment cores from sites in the historic Everglades allowed us to document the natural variability of the ecosystem over the past 2,000 years and contrast it to 20th century changes in wetland plant communities. The natural system included extensive water-lily sloughs, sawgrass ridges, and scattered tree islands extending from Lake Okeechobee southward through Shark River Slough. Between ~1000 AD and 1200 AD, weedy species such as Amaranthus (water hemp) became more abundant, indicating decreased annual rainfall, shorter hydroperiods, and shallower water depths during this time. After ~1200 AD, vegetation returned to its pre-1000 AD composition. During the 20th century, two phases of hydrologic alteration occurred. Completed by 1930, the first phase included construction of the Hoover Dike, canals linking Lake Okeechobee to the Atlantic Ocean, and the Tamiami Trail. Reconstructions of plant communities indicate that these changes shortened hydroperiods and lowered water depths throughout the Everglades. The extent of water-lily slough communities decreased, and tree islands became larger in Shark River Slough. The second phase resulted from construction of canals and levees in the 1950s, creating three Water Conservation Areas. The response of plant communities to these changes varied widely depending on location in the Everglades. In Loxahatchee NWR, weedy and short-hydroperiod plant species became more abundant in marshes, and species composition of tree islands changed. In Water Conservation Area 2A, cattail replaced sawgrass in marshes with high nutrient influx; the ridge and slough structure of the marshes was replaced by more homogeneous sawgrass marshes; sustained high water levels for more than a decade resulted in loss of tree islands that had existed for more than 1,000 years. In Everglades National Park, the extent of slough vegetation decreased further. Near Florida Bay, the rate of mangrove intrusion into fresh-water marshes

    Full Text Available Astronomy was revolutionized in the 20th century. The electron was discovered in 1897 and this transformed spectroscopy and introduced plasma and magnetohydrodynamic physics and astro-chemistry. Einstein’s E = mc2, solved the problem of stellar energy generation and spawned the study of elemental nuclear synthesis. Large telescopes led to a boom in astronomical spectroscopic and photometric data collection, leading to such cornerstones as the Hertzprung-Russell diagram and the mass-luminosity relationship, and to the realization that the Universe contained a multitude of galaxies and was expanding. Radio astronomy was introduced and the advent of the space age saw the astronomical wavelength range expand into the ultraviolet, X-ray and gamma-ray regions, as well as the infrared and millimetre. We also startedwandering around roaming the Solar System instead of merely glimpsing its members from the bottom of our warm, turbulent atmosphere. Astronomical “breakthroughs” abounded. We have asked astronomers to select their “top ten” and these are listed and discussed in this paper.

    Full Text Available The paper explores the potential impact of studying the 20th century philosophical adventure fiction on educational process. In spite of the well-recognized idea of M. M. Bakhtin about the equality of classical and grotesque-fantastic aesthetic traditions, the former still predominates in the secondary and higher school curricula. The research aims to demonstrate the educational opportunities of the philosophical adventure fantasy; the content of the given concept being defined along with its specific features: unconditional world description, experimental plot type, discrepancy between the fantastic world created by the author and the real laws of nature, the hero’s experience in the alien world, related moral and philosophical problems.The author substantiates the idea of incorporating  the number of philosophical adventure novels into the Literature course in secondary schools, and the Theory and History of Literature course in  the higher schools of the humanities profile to facilitate the detailed and in-depth comprehension of theoretical topics concerning literary genres, types of literary heroes, grotesque adventure traditions, fantasy types, etc.

    1995-12-12

    Not until the 19th century theories on sleep were based upon experimental findings in animal and humans. The so-called 'hypnotoxin theory' culminated, when Legendre and Piéron successfully induced sleep in a dog by transmission of cerebrospinal fluid from a dog deprived of sleep. The main discussion concerning the origin of sleep has been the question if sleep is a passive or an active state. Similarities with coma, the positive Babinski sign and pathoanatomical findings in patients who died after encephalitis lethargica were the arguments for the 'deafferentiation hypothesis'. Bremer's classical brainstem-transsections in cats confirmed this idea. Pavlov was the major representative of the idea that sleep was due to a general inhibition of the brain. Hess induced physiological sleep in cats by electrical stimulation of the diencephalon, proving the active nature of sleep. The introduction of the EEG in animals by Caton and in humans by Berger allowed for the first time the measurement of sleep depth without waking the sleeper. After discovery of the REM sleep periods by Aserinsky and Kleitman in 1953 and the demonstration of periodical sleep cycles by Dement and Kleitman, polysomnography with simultaneous whole night recording of EEG, EMG, electrooculogram and other physiological parameters was established as the major diagnostic tool in sleep disorders. One of the most important questions about the function of sleep is still unresolved. NREM sleep is believed to have a restorative function, whereas REM sleep might be involved in learning processes. According to the sleep interpretation of Sigmund Freud, the dream content represents endogenous wishes which cannot be expressed during wakefulness because of an internal 'sensor'. A more recent theory by Hobson explains the dreams by a very unspecific brainstem activity occurring during REM sleep which projects to the frontal brain and activates stored memory. The most important sleep disease of the 20th century is

    Food security and the overall wellbeing of human kind are threatened by overexploitation of our freshwater resources. Water scarcity is not only a threat to people, but also to many of the planet's key ecosystems. Due to increasing population pressure, changing water consumption behaviour, and climate change, the threat is projected to become even worse in the future. Water can be physically scarce in two ways: population-driven water shortage occurs in areas where a large population has to depend on a limited resources (indicated by m3/capita/yr), while demand-driven water stress is related to the excessive use of otherwise sufficient water resources (indicated by demand/supply ratio). Although many studies have increased our understanding of current water scarcity and how this may increase in the future, the understanding of trajectories with the past development of the water scarcity is less well understood. To date, studies of past water resources have focused on either water shortage or water stress. We aim to calculate global water scarcity, both water stress and water shortage, for the period 1900-2005. We can thus provide, for the first time, continuous regional trends and local analyses of trajectories of water scarcity for the entire 20th century. By including both dimensions of water scarcity, we can increase the understanding of reasons behind the scarcity. We found that in year 1900 13% of the population (i.e. 0.22 billion people) was living in areas that suffer some kind of water scarcity (0.2), while in year 2005 this percentage has increased to 57% (3.80 billion). Especially the population suffering from both high water stress (ratio >0.4) and high water shortage (Pakistan and parts of India and Northern China. The region of sub-Saharan Africa mainly suffers from water shortage. We used WaterGAP model to simulate the water use and available water resources. WaterGAP was forced with WATCH data. For the past population, we used HYDE dataset. The water

    Advances in understanding of the white light faculae measured at the Royal Greenwich Observatory from 1874 to 1976 suggest that they offer a more direct measure of solar brightening by small diameter photospheric magnetic flux tubes than do chromospheric proxies. Proxies such as the area of Ca K plages, the Mg index or the microwave flux include many dark photospheric structures as well as pores and sunspots. Our reconstruction of variation in total solar irradiance,TSI,based on the faculae indicates that the sun dimmed by almost 0.1 percent in the mid- twentieth century rather than brightening as represented in previous reconstructions. This dimmimg at the sun's highest activity level since the seventeenth century is consistent with the photometric behavior observed in somewhat younger sun like stars. The prolonged TSI decrease may have contributed more to the cooling of climate between about 1940 and 1970 than present models indicate.

  8. [Turning points in American psychiatry of the 20th century].

    Sabshin, M

    1990-09-01

    Sabshin describes three turning points in twentieth century American psychiatry. Following "the time of the Thirteen", the time of the founders of modern American psychiatry, the first turning point was marked by the rise of Meyerian psychobiology and had its peak impact during the second quarter of the twentieth century. In the post World War II years diverging therapeutic ideologies became dominant, including the important impact of psychoanalysis. But competing ideologies (e.g. in social and biological psychiatry) were of importance also. The most recent turning point was marked by the current surge of neuro-science and psychopharmacology along with empiricism and logical positivsm. It is predicted to peak in the middle of the current decade. Following the preceding demedicalization a remedicalization of psychiatry was the result. For the turn of the 21st century, as Sabshin predicts, a re-emergence of analogues of Meyerian psychobiology will take center stage, particularly concentrating on questions of coping and adaptability, on how the human being keeps himself healthy and sane during subsequent developmental stages as well as in the face of stressful life events.

  10. Radiation legacy of the 20th century: Environmental restoration

    International Nuclear Information System (INIS)

    As a result of events in the twentieth century, mainly related to the development of nuclear energy, mankind has been forced to deal with the restoration of the environments which contain radioactive residues. The International Conference RADLEG-200 was particularly focused on the radioactive legacy of the countries of the former Soviet Union and eastern Europe. By means of reviews and case studies the conference assessed the overall situation with respect to the contaminated sites and sources of potential environmental contamination and evaluated the achievements of rehabilitation and remediation programmes as well as identifying future needs in this field. The Conference was attended by 266 participants from 16 countries and 6 international organizations with 49 papers presented orally and 64 presented as posters. This publication contains the 49 orally presented papers, each of them was indexed separately

    1998-06-01

    This volume provides a broad synthesis of conceptual developments of twentieth century field theories, from the general theory of relativity to quantum field theory and gauge theory. The book traces the foundations and evolution of these theories within a historio-critical context. Theoretical physicists and students of theoretical physics will find this a valuable account of the foundational problems of their discipline that will help them understand the internal logic and dynamics of theoretical physics. It will also provide professional historians and philosophers of science, particularly philosophers of physics, with a conceptual basis for further historical, cultural and sociological analysis of the theories discussed. Finally, the scientifically qualified general reader will find in this book a deeper analysis of contemporary conceptions of the physical world than can be found in popular accounts of the subject.

    Physics of the 20th century has contributed significantly to modern technology, and yet many physics students are never availed the opportunity to study it as part of the curriculum. One of the possible reasons why it is not taught in high school and introductory physics courses could be because curriculum designers believe that students need a solid background in classical mechanics and calculus in order to study physics of the 20th century such as the photoelectric effect, special and general relativity, the uncertainty principle, etc. This presumption may not be justifiable or valid. The authors of this paper contend that teaching physics of the 20th century aids students in relating physics to modern technology and the real world, making studying physics exciting. In this study, the authors correlated scores for matched questions in the Mechanics Baseline Test and a physics of the 20th century test in order to examine the trend of the scores. The participants included undergraduate students attending an introductory algebra-based physics course with no intention of taking physics at a higher level. The analysis of the scores showed no significant correlation for any of the matched pairs of questions. The purpose of this article is to recommend that even without a solid background in classical mechanics, teachers can introduce physics of the 20th century to their students for increased interest.

    2014-05-01

    Full Text Available This article considers some preliminary reflections in view of a 20th century theatre-and-neuroscience history. Up to now, the history of the 20th century theatre has been too fragmentary and irregular, missing out on the subterranean links which, either directly or indirectly, bound different experiences. The article aims to put in evidence the recurrent problems of these encounters. The hypothesis of the essay concerns the possibility of gathering and grouping a great part of the relationships between theatre and neuroscience around four trajectories: the physiology of action, the physiology of emotions, ethology, and studies on the spectator’s perception.

    Full Text Available In the early 20th century, some American ministers were eager participants in the Chautauqua and Lyceum lecture circuits that flourished across the Midwest and beyond. Ministers expressed their vocation in the public arena, and the Redpath Chautauqua collection shows how part of this public life was conducted. In their role as lecturers in multiple educational and civic venues, ministers functioned as experts on the Bible, as well as supporting American ideals that were loosely connected to Protestant Christianity. The essay explores how a substantial archival collection reveals a particular public role ministers played in a popular culture venue in early 20th century America.

    What makes the 21st century different from the 20th century? This century is the century of extremes -- political, economic, social, and global black-swan events happening with increasing frequency and severity. Book of Extremes is a tour of the current reality as seen through the lens of complexity theory – the only theory capable of explaining why the Arab Spring happened and why it will happen again; why social networks in the virtual world behave like flashmobs in the physical world; why financial bubbles blow up in our faces and will grow and burst again; why the rich get richer and will continue to get richer regardless of governmental policies; why the future of economic wealth and national power lies in comparative advantage and global trade; why natural disasters will continue to get bigger and happen more frequently; and why the Internet – invented by the US -- is headed for a global monopoly controlled by a non-US corporation. It is also about the extreme innovations and heroic innovators yet t...

During the first half of the 20th century the existence of Serbian people in Turkey (later in Greece was acknowledged through school and church. Thanks to the Serbian schools, Serbs as an invisible minority became a visible one. In the second half of the 20th century there is primarily a teaching of Serbian language as a foreign language. During this period, Serbian was accepted primarily by Greeks at courses and private classes. At the beginning of the nineties in the 20th century because of the war in the territory of Yugoslavia, a large number of refugees went to Greece. Teaching of Serbian as a native language was organized only ten years later (at the beginning of 21st century. In some places, the schools are located in consular sections and have the assistance of the country of origin (Thessalonica, Katerini while in Hani (Crete immigrants organized them-selves without the assistance from the country of origin.

    Full Text Available According to data of IPCC (Intergovernmental Panel for Climatic Change, the global surface air temperature increased to 0,6 ± 0,2 °C in the 20th century. Weber G. R., (1995 quotes that there is a trend of cold in the last 60 years in the middle latitudes including Europe, too. Starting from already mentioned perplexities we have tried to perceive the problem of climate variability in Serbia in the second half of the 20th century, when it came to very important increasing of concentration of CO2. With that aim we observed the decade values of average annual temperatures in the network of 20 climatic stations. In the period 1951 - 1990 a decrease of temperature was registered in 13 stations while in other stations an increase was less than 0,1 °C. Explorers from Bulgaria (Alexandrov V., 2000 and Hungary (Domonkos P., Zoboki J., 2000 came to similar results, too. However, if we take in account the last decade 20th century the number of stations with positive changes is enlarged on 15. Stations that have small changes and those with decrease of temperature were localized in the south and south eastern part of the country, and they are mainly coincided with before separated climatic regions with maritime pluviometric regime (Radovanović M., 2001. Using Dzerdzevskis B. L., (1975 division on three main types of circulation in the north hemisphere, we found that the increase of temperatures in the last decade 20th century is above all caused by change of dominant type of circulation from the south meridian to zonal. An analysis of seasonal changes showed that in the last five decades 20th century it came to decrease of winter temperatures in almost half of the stations in contrast with results of paleoclimatics models of possible greenhouse effect.

    Droughts are becoming the most expensive natural disasters in China and have exerted serious impacts on local economic development and ecological environment. The fifth phase of the Coupled Model Intercomparison Project (CMIP5) provides a unique opportunity to assess scientific understanding of climate variability and change over a range of historical and future period. In this study, fine-resolution multimodel climate projections over China are developed based on 7 CMIP5 climate models under RCP8.5 emissions scenarios by means of Bilinear Interpolation and Bias Correction. The results of downscaled CMIP5 models are evaluated over China by comparing the model outputs with the England Reanalysis CRU3.1 from 1951 to 2000. Accordingly, the results from the output of downscaled models are used to calculate the Standardized Precipitation Index (SPI). Time series of SPI has been used to identify drought from 20th century to 21st century over China. The results show that, most areas of China are projected to become wetter as a consequence of increasing precipitation under RCP8.5 scenarios. Detailed examination shows that the SPI show a slightly increasing trend in the future period for the most parts of China, but drought in Southwest region of China will become the norm in the future RCP8.5 scenarios.

  7. Solar cycle length and 20th Century northern hemisphere warming: Revisited

    Science.gov (United States)

    Damon, Paul E.; Peristykh, Alexei N.

    It has been suggested that the length of the solar cycle (SCL) is related to solar forcing of global climate change [Friis-Christensen and Lassen, 1991]. Although no physical mechanism had been proposed, the relation seemed to be supported by interesting correlations with several paleoclimate records and, separately, with the 20th century Northern Hemisphere instrumental record. Actually, what has been correlated is the quasi-sinusoidal Gleissberg cycle which is slightly greater in the 18th century than in the 20th century. Using the pre-industrial record as a boundary condition, the SCL-temperature correlation corresponds to an estimated 25% of global warming to 1980 and 15% to 1997.

    Full Text Available Desert dust perturbs climate by interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean and land biogeochemistry. While we know that desert dust is sensitive to perturbations in climate and human land use, previous studies have been unable to determine whether humans were in the net increasing or decreasing desert dust. Here we present observational estimates of desert dust based on paleodata proxies showing a doubling of desert dust during the 20th century over much, but not all the globe. Large uncertainties remain in estimates of desert dust variability over 20th century due to limited data. Using these observational estimates of desert dust change in combination with ocean, atmosphere and land models, we calculate the net radiative effect of these observed changes (top of atmosphere over the 20th century to be −0.14±0.11 W/m2 (1990–1999 vs. 1905–1914. The estimated radiative change due to aerosols is especially strong between the dusty 1980–1989 and the less dusty 1955–1964 time periods (−0.57±0.46 W/m2, which model simulations suggest may have reduced the rate of temperature increase between these time periods by 0.11 °C. Model simulations also indicate strong regional shifts in precipitation and temperature from the desert dust changes, causing 6 ppm (12 Pg C reduction in model carbon uptake by the terrestrial biosphere over the 20th century. Desert dust carries iron, an important micronutrient for ocean biogeochemistry that can modulate ocean carbon storage; here we show that dust deposition trends increase ocean productivity by an estimated 6% over the 20th century, drawing down an additional 4 ppm (8 Pg C of carbon dioxide into the oceans.

    Parenteral nutrition (PN) and enteral nutrition (EN) have a very long history, emerging in the ancient world and developing throughout the common epoch. This history dates back as far as 3500 bc to the ancient Egyptians, Indians, and Chinese. Their medical practices were the first reports of enteral feeding therapy, provided via rectum with enemas of wine, milk, whey, wheat, and barley. Hippocrates and Plato, in ancient Greece, were the first personalities to emphasize the importance of diet on health. In the following centuries, Erasistratus and Herophilus described the first notion of the circulatory system, and Oribasius and Celsus described the role of nutrition and disease. There is a great historical gap between the times of Galen (2nd century), who elaborated on the circulatory system; Ibn Zuhr (12th century), who constructed the first model of PN; and Capivacceus (16th century), who placed the first tube for EN. The 17th-19th centuries showed major developments in modern nutrition elements. Steps toward artificial nutrition began in 1628 with the detailed description of blood circulation by William Harvey; however, most of the advances in enteral and parenteral feeding techniques, solutions, and formulas took place in the 20th century. Over the last decade of the 20th century, research focused on metabolic control, multitude formulas, timing and the combination of EN and PN for intensive care patients.

  17. Changes in the global freshwater N and P cycles over the 20th century

    Dramatic world-wide changes occurred during the 20th century in both nutrient delivery and in-stream retention. In this paper, we use a combined nutrient-input, hydrology, in-stream nutrient retention model to quantitatively track the changes in the global freshwater N and P cycles over the 20th century. Global nutrient delivery almost doubled due to expanding agriculture and increasing wastewater discharge. Nutrient retention also increased by a factor of two as a result of the rapidly growing number of dams and reservoirs. This increase in nutrient retention could not balance the increase in nutrient delivery to rivers. River export to coastal seas increased during the 20th century from 19 to 37 Tg yr-1 of N and 2 to 4 Tg yr-1 of P. There are important differences in riverine N:P export ratios in various parts of the world resulting from the interplay of multiple processes and economic activities in different river basins. Increasing nutrient loading of freshwater systems is a threat to water quality. Furthermore, the global river export increase in the molar N:P ratio during recent decades may affect the ecology within both the river basins and the coastal system. This ratio change may be driven by the recent stagnation of P fertilizer use in most industrialized countries, in comparison to the ever increasing N fertilizer use.

  18. Sea Level did not Accelerate in the Last Quarter of the 20th Century

    The Permanent Service for Mean Sea Level (PSMSL)collects quality-controlled sea levels from tide gages on all seas, and tabulates them at www.pol.ac.uk/psmsl/psmsl(underline)individual(underline)stations.html. I examined annual average sea levels (Ra in column 6) for generally open-coast tide gages having data at the years defining quarter points in the 20th century: 1900, 1925, 1950, 1975, 2000. Gages lacking data for a given date, say 1975, were assumed to qualify if they had data for one year, plus or minus, of the missing data, i. e., for 1974 or 1976 in this example. This examination of data from gages on all seas identified 54 gages with data for the last three of the five dates, which included 26 gages with data for the last four of the five dates, which included 7 gages with data for all five dates. This means that sea-level change during the last quarter (Q4) of the 20th century could be compared at 54 sites with sea-level change in Q3, at 26 sites with sea- level change in Q2, and at 7 sites with sea-level change in Q1, providing 87 tests of the widely reported acceleration in rate of sea-level rise at the end of the 20th century. If sea level is rising at an accelerating rate, then sea-level rise during Q4 should almost always exceed sea-level rises in Q1, Q2, and Q3 of the 20th century. Of the 87 tests, 44 showed more sea-level rise in Q4, and 43 showed less sea-level rise in Q4, compared to the earlier quarters. Thus there is no evidence for an accelerating rise in sea level at the end of the 20th century from these quality-controlled data. The data do indicate that sea-level changes are synchronized over long reaches of shoreline (Sturges, 1990), and sites where gages are imbedded in deposits of clastic sediment have higher apparent sea-level rise attributable to sediment compaction. Beach erosion on the East Coast of the U.S. is widely attributed to the acceleration of sea-level rise, yet all 8 long-term gages at this coast show significantly LESS

    2014-01-01

    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. PMID:24983802

    2007-01-01

    The impacts of external forcing, including natural and anthropogenic, on the 20th century global warming were assessed with the use of the Grid Atmospheric Model of IAP/LASG Version 1.1.0, following the standard coordinated experiment design of the Climate Variability and Predictability (CLIVAR) International Climate of the Twentieth Century Project (C20C), Phase II. The results indicate that external forcing plays an important role in the evolution of the land surface air temperature on interannual, decadal, and interdecadal time scales, and contributes greatly to the global warming in the following two periods: the early twentieth century between the 1910s and the 1940s and the late twentieth century after the 1970s. External forcing also has strong impact on the regional temperature change during the two warming periods except for parts of the Eurasia and the North America continents. In the cooling period, however, the impact of internal variability is dominant.

    This study asks two related questions about the shifting landscape of marriage and reproduction in US society over the course of the last century with respect to a range of health and behavioral phenotypes and their associated genetic architecture: (i) Has assortment on measured genetic factors influencing reproductive and social fitness traits changed over the course of the 20th century? (ii) Has the genetic covariance between fitness (as measured by total fertility) and other traits changed over time? The answers to these questions inform our understanding of how the genetic landscape of American society has changed over the past century and have implications for population trends. We show that husbands and wives carry similar loadings for genetic factors related to education and height. However, the magnitude of this similarity is modest and has been fairly consistent over the course of the 20th century. This consistency is particularly notable in the case of education, for which phenotypic similarity among spouses has increased in recent years. Likewise, changing patterns of the number of children ever born by phenotype are not matched by shifts in genotype-fertility relationships over time. Taken together, these trends provide no evidence that social sorting is becoming increasingly genetic in nature or that dysgenic dynamics have accelerated. PMID:27247411

    Twentieth-century disease, or total allergy syndrome, is a condition attributed to hypersensitivity to the environment that may sometimes be seen as so serious that the patient is incapable of living in the modern world. Although the popular media frequently carry stories about it, there is little scientific literature. It is diagnosed by clinical ecologists, who maintain, among other theories, that susceptible individuals experience an overload in assaults by artificial materials in the environment. The patients usually have multiple ill defined symptoms for which no organic cause can be found, but they vigorously resist psychiatric referral, as they attribute their symptoms to allergy. A group of 18 patients who were purportedly suffering from 20th-century disease were referred to a university psychiatric consultation liaison service. They virtually all had a long history of visits to physicians, and their symptoms were characteristic of several well known psychiatric disorders. The case histories and management of three of them are presented. Although this group of patients may have been atypical in that they had more severe psychologic symptoms, the experience indicates that a psychiatric diagnosis ought to be considered. The symptoms of 20th-century disease have much in common with other conditions known to physicians for centuries.

    Several scenario experiments of the IPCC 4th Assessment Report (AR4) are performed by version g1.0 of a Flexible coupled Ocean-Atmosphere-Land System Model (FGOALS) developed at the Institute of At- mospheric Physics, Chinese Academy of Sciences (IAP/CAS), including the "Climate of the 20th century experiment", "CO2 1% increase per year to doubling experiment" and two separate IPCC greenhouse gases emission scenarios AIB and B1 experiments. To distinguish between the different impacts of natural vari- ations and human activities on the climate change, three-member ensemble runs are performed for each scenario experiment. The coupled model simulations show: (1) from 1900 to 2000, the global mean temper- ature increases about 0.5℃ and the major increase occurs during the later half of the 20th century, which is in consistent with the observations that highlights the coupled model's ability to reproduce the climate changes since the industrial revolution; (2) the global mean surface air temperature increases about 1.6℃ in the CO2 doubling experiment and 1.5℃ and 2.4℃ in the AlB and Bl scenarios, respectively. The global warming is indicated by not only the changes of the surface temperature and precipitation but also the temperature increase in the deep ocean. The thermal expansion of the sea water would induce the rise of the global mean sea level. Both the control run and the 20th century climate change run are carried out again with version g1.1 of FGOALS, in which the cold biases in the high latitudes were removed. They are then compared with those from version g1.0 of FGOALS in order to distinguish the effect of the model biases on the simulation of global warming.

    Full Text Available Throughout the history of Psychopathology, several meanings have been assigned to the term melancholia. The main ones were related to affective (fear and sadness and thought disorders (a type of mental disorder characterised mainly by the presence of abnormal believes. At the time of Hippocrates melancholia was regarded mainly in its affective component. Since that time, and until the 18th century, authors and opinions have been divided, with both aspects (affective and thought disorders, being valued. Finally, in the 18th-19th centuries, with Pinel at its peak, melancholia becomes exclusively a synonym of thought disorders (abnormal believes: delusions/overvalued ideas.At the turn of the 19th to the 20th century, the affective component returns as the main aspect characterising melancholia.

    2005-01-01

    Based on the reanalysis data throughout 1948―2002 as derived from the United States National Centers for Environmental Prediction and National Center for Atmospheric Research, it is revealed that East Asian summer monsoon (EASM) intensity weakens on an interdecadal timescale since the mid-1960s, and twice interdecadal jumps are recorded in the EASM intensity index series in the late 20th century, respectively occurring in the mid-1960s and mid- to late 1970s. Six globally coupled atmosphere-ocean models' outputs under the SRES A2 greenhouse gas and aerosol emission scenario, provided by the IPCC Data Distribution Center and the Hadley Center for Climate Prediction and Research, are then systematically examined. It follows that the above EASM weakening is not closely related to synchronizing anthropogenic global warming, and, therefore, it should be qualitatively natural change process. Over the 21st century, the EASM intensity is likely increased slightly by continually intensified greenhouse effect relative to the late 20th century.

    Full Text Available Longevity runs in families, either through genetic or environmental influences. Using Quebec civil registration and historical Canadiancensuses, we compared the longevity of siblings and spouses of 806 centenarians to a group of controls, all born in Quebec at the turnof the 20th century. Our results show that siblings of centenarians, who share half of their genes and a common childhood environment,lived 3–4 years longer than their birth cohort. However, husbands and wives of centenarians lived 4 and 2.5 years longer than theircounterparts of the same sex, respectively, suggesting that longevity is also modulated by shared environment in adulthood.

    2011-12-01

    Full Text Available The aim of the paper is the research of transformation of formatting information on banknotes during the 20th century, which is the period of some of the greatest graphical innovations after Gutenberg’s invention of movable type printing. Computer graphics had taken over in the field of typography in the exact moment of hand engraving’s highest level of art in the creation of the font cut. About forty years ago, the era of etching used in copper etching and steel engraving in hand - made drawings had begun, along with the use of phototypesetting as the representative of digital technology. Quality of the written lines has introduced microtypography as a special method of rasterization in the background of banknotes. In Croatia, the above mentioned modifications are present through the works of our typographers, even though the multiplication of banknotes was done in foreign printing houses that had appropriately protected printing technology. The paper contributes to the scientific analysis of the technical aspect of banknote making on Croatia’s soil during the course of the 20th century, and this, with the methods of analysis and synthesis incorporated, gives a clear picture and transparency into the method of banknote making, both from a technological and development cycle - making aspect. Given the fact that not only the Croatian banknotes are examined, analysis contributes to comparative procedures of local scopes in the field of technological manufacture of other banknotes that belong to the same time period.

    In general, the history of environmental research is not known very well. Our study contributes to filling this gap by focusing on the history of the methods that were used during the 20th century to study the state of the urban sea area in Helsinki, Finland. From the beginning of the past century, the methodological basis of municipal water pollution studies in Helsinki was broad, involving the use of physical, chemical, hygienic and biological methods. Since 1904, municipal laboratories have overseen and conducted most physico-chemical and bacteriological studies of pollution of urban watercourses, and they have done regular annual sampling since 1947. In the 1920s and 1930s, the municipal laboratories cooperated with the University of Helsinki and, secondarily, with the Helsinki University of Technology in order to develop the skills and manpower that were required in order to conduct pollution studies. Statutory monitoring was initiated in the mid-1960s, and it continues today. (orig.)

    Full Text Available Unlike the new age of migration that we are experiencing now, the social mobility specific to the end of the 19th century and the beginning of the 20th century may be defined by the expression “one way ticket”; the immigrant, usually a man, used to leave his country of origin and settle for good in his host-country (he did not look for his happiness from state to state, as it happens now. The Romanian migration of that time was directed mainly towards the New World (particularly to the USA, and less to Canada. This paper is an attempt to sketch the image of Romanian emigration by taking into account the peculiarities determined by: emigration causes, geographical predominance, social composition, occupational options in the host-country, and the structure of Romanian immigrant communities.

  16. Atom pictures. Iconography of the atom in science and public of the 20th century

    International Nuclear Information System (INIS)

    The 20th century can be described as century of the atom. From the development of molecular models until nanotechnology, from Becquerel's discovery of the radioactivity until the reactor accident in Chernobyl was and remains the atom subject of the research as well as of the discussion in culture and politics. Thereby the concept and the imagination of the ''atom'' have been subjected to manifold changes, which were essentially generated by pictures. The volume summarizes famous as well as less famous pictures from laboratories, exhibitions, publications, and films. It gives both a contribution to the history of science and culture and a summarizing of different disciplinary approaches to the circulation of pictures between science and public

    The history of tuberculosis as a worldwide fatal illness traces back to antiquity, a well-known disease in ancient civilizations. However, its causative agent remained unidentified until the last decades of the 19th century, when discovered by Robert Koch. In due course, preparation of the BCG vaccine, application of the Mantoux intradermal diagnostic tuberculosis test and administration of proper antituberculosis medications eventually controlled tuberculosis. However, despite these significant advancements tuberculosis remained uneradicated, particularly in developing countries after the emergence of both multidrug-resistant tuberculosis and HIV co-infection. Presented here, is a brief review of the history of tuberculosis in the world as well as its historical background in Iran, mainly during the 19th and 20th centuries.

    In this study, we provide a determination of the 20th Century (1900--2002) global sea level rise, the associated error budgets, and the quantifications of the various geophysical sources of the observed sea level rise, using data and geophysical models. We analyzed significant geographical variations of the global sea level including those caused by the steric component (heat and salinity) in the ocean, and the self-gravitational signal as a result of ice sheets melting, including the effects of glacial isostatic adjustment (GIA) since the Pleistocene. In particular, relative sea level data from long-term (longest is 150 year records) and over 600 tide gauge sites globally from PSMSL and other sources, and geocentric sea level data from multiple satellite altimetry (1985--2005) have been used to determine and characterize 20th century global sea level rise. Altimeter and selected tide gauge sea level data have been used for the 20th century sea level determination, accounting for relative biases between the altimeters, effects of sea level corresponding to oceanic thermal expansion, vertical motions affecting tide gauge measurements, self gravitations, and barotropic ocean response. This study is also characterized by the roles of the polar ocean in the global sea level study and addressing the question whether there is a detectable sea level rise acceleration during the last decade. Vertical motions have been estimated by combining geocentric sea level measurements from satellite altimetry (TOPEX/POSEIDON) and long-term relative (crust-fixed) sea level records from global tide gauges using the Gauss-Markov (GM) model with stochastic constraints. The study provided a demonstration of improved vertical motion solutions in semi-enclosed seas and lakes, including Fennoscandia and the Great Lakes region, showing excellent agreement with independent GPS observed radial velocities, or with predictions from GIA models. In general, the estimated uncertainty of the observed

    van de Giesen, Nick

    2010-05-01

    In this presentation, an overview is given of global dam building activities in the 20th century. Political, economical and hydrological factors shaped the building of large dams. The development of the relations between these three factors and dam building over time is examined. One can argue whether or not history is simply "one damn thing after another" but the second half of the 20th century suggests that history is at least reflected by the construction of one dam after another. The financial crisis of the 1930's started the first construction wave of large hydropower dams in the United States. This wave continued into the Second World War. During the Cold War, the weapon race between the USA and USSR was accompanied by a parallel neck-and-neck race in dam construction. By the 1970's, dam construction in the USA tapered off, while that in the USSR continued until its political disintegration. In China, we see two spurts in dam development, the first one coinciding with the disastrous Great Leap Forward and the second with the liberalization of the Chinese economy after the fall of the Berlin Wall. Economic and political events thus shaped to an important extent decisions surrounding the construction of large dams. Clearly, there are some hydrological prerequisites for the construction of dams. The six largest dam building nations are USSR, Canada, USA, China, Brazil, and India, all large countries with ample water resources and mountain ranges. Australia has relatively little reservoir storage for the simple fact that most of this country is flat and dry. A few countries have relatively large amounts of reservoir storage. Especially Uganda (Owens Falls), Ghana (Akosombo), and Zimbabwe (Kariba) are examples of small countries where gorges in major rivers were "natural" places for large dams and reservoirs to be built early on. It seems that, deserts aside, the average potential storage capacity lies for most continents around 10 cm or about 50% of the total

    Worm Hansen, Casper

    Exploiting pre-intervention variation in flu/pneumonia, tuberculosis and maternal mortality, together with time variation arising from medical breakthroughs starting in the late 1930s, this paper studies the aggregate impact of large health shocks across US states. The analysis demonstrates......, the decline in maternal mortality has a fragile, but positive relationship with income per capita. Because these specific health shocks affected mortality across the life cycle differently, the evidence here underscores the general tenet of regarding health as multifaceted....... that the shocks influenced income per capita in different ways. While the shock to flu/pneumonia mortality has been conductive for development, the large reduction in the incidence of tuberculosis deaths has been a negative force in the development of US states over the second-half of 20th century. In addition...

    Full Text Available One component of the heritage of publicly funded property developments put up since the Second World War is residential districts designed by leading architects in which upgrading has to take into account considerations of safeguarding. The raising of the threshold from 50 to 70 years before safeguarding norms come into effect means that local authorities and management companies have sole responsibility for the modification and safeguarding of this heritage. This paper looks at some examples of 20th century housing estates designated for upgrading in order to highlight the specific strategies adopted, selected from a range of actions based on the need for accurate knowledge and collective agreement by all the parties involved right from the design phase.

    Full Text Available Estimates of the contribution of glaciers to sea-level rise during the 20th century that were published in recent years are strongly divergent. Advances in data availability have allowed revisions of some of these published estimates. Here we show that outside of Antarctica, the global estimates of glacier mass loss obtained from glacier-length-based reconstructions and from a glacier model driven by gridded climate observations are now consistent with each other, and also with an estimate for the years 2003–2009 that is mostly based on remotely sensed data. This consistency is found throughout the entire common periods of the respective data sets. Inconsistencies of reconstructions and observations persist in estimates on regional scales.

    At the end of the 20th century Eissler looks back to its beginnings and the outside figure of Sigmund Freud. What good have Freud's discoveries done? What progress have they promised and which of those promises have actually been redeemed? What kind of track record does psychoanalysis have to show for itself? The author undertakes a careful assessment of Freud's stature, his limitations and his scientific achievements, and comes to the skeptical conclusion that in the last resort it was in fact the founder of psychoanalysis who destroyed the illusion he himself had long subscribed to, i.e. that there is an indissoluble link between the increase of scientific knowledge and the salvation of homo sapiens. For Eissler's Freud the survival of humanity and the scientific civilization created by mankind are irreconcilable.

    Directory of Open Access Journals (Sweden)

    Simon Krek

    2013-05-01

    Full Text Available In the 20th century structuralism established itself as the central linguistic theory, in the first half mainly through its originator Ferdinand de Saussure, and in the second half with the figure of Noam Chomsky. The latter consistently refused to acknowledge analysis of extensive quantity of texts as a valuable method, and favoured linguistic intuition of a native speaker instead. In parallel with structuralism other trends in linguistics emerged which pointed to the inadequateness of the prevailing linguistic paradigm and to theoretical insights which were only possible after the systematic analysis of large quantities of texts. The paper discusses some of the dilemmas stemming from this dichotomy and places corpus linguistics in a broader linguistic context.

    The late 19th and early 20th centuries ushered in a number of significant events that helped advance the nursing profession in its early development. Nursing leaders began to show interest in the reform movements under way, such as woman's suffrage, settlement houses, and labor activities. They knew that nurses were not alone in their struggle to improve the health of the public. Philanthropic groups abounded, working for social betterment as well as for changes needed in overcrowded tenements, food inspection, and information to the nation about healthy living (1). In addition, serious concerns surfaced in the profession relating to the proliferation of training schools and reforms required in the educational system. PMID:10754856

    2015-01-01

    We show that the monthly recorded history (1878-2013) of the Southern Oscillation Index (SOI), a descriptor of the El Ni\\~no Southern Oscillation (ENSO) phenomenon, can be well described as a dynamic system that supports an average nonlinear predictability well beyond the spring barrier. The predictability is strongly linked to a detailed knowledge of the topology of the attractor obtained by embedding the SOI index in a wavelets base state space. Using the state orbits on the attractor we show that the information contained in the Southern Oscillation Index (SOI) is sufficient to provide average nonlinear predictions for time periods of 2, 3 and 4 years in advance throughout the 20th century with an acceptable error. The simplicity of implementation and ease of use makes it suitable for studying non linear predictability in any area where observations are similar to those that describe the ENSO phenomenon.

    During the whole 20th century in China, especially the latest 50 years, we have gotten much geological information about geological mapping, geophysics, geochemistry, mineral exploration,remote sensing, environmental geology, hydrogeoiogy, engineering geology and oceanic geology etc. by our geologists and explorers. All the information has been accumulated and can be used as a decisionmaking foundation for the future plan of geological survey. The spatial database of geological survey extents has been established by using computer technology. The database contained all kinds of exploration sections and collected about 160 000 records in this database. This paper introduces the data construction, contents and applying system of this database, and trys to let people know what kinds of geological survey were finished, when the exploration were carried out, and how and where you can get this information.

  9. Anthropogenic aerosols may have increased upper tropospheric humidity in the 20th century

    Directory of Open Access Journals (Sweden)

    M. Bister

    2011-05-01

    Full Text Available Recent simulations of deep convection with a spectral microphysics cloud model show that an increase in aerosol concentration can have a significant effect on the nature of convection with more ice precipitation and less warm rain in polluted air. The cloud lifetime and the area covered by cloud anvils of deep convection are also larger for polluted air. Therefore, it is possible that the increase of anthropogenic aerosols in most of the 20th century has increased humidity and perhaps also cloudiness in the mid- to upper troposphere. Satellite data of upper tropospheric relative humidity in 1979–1997 and observed changes in cloudiness support this hypothesis. As changes in upper tropospheric humidity strongly affect longwave radiation, it is possible that anthropogenic aerosols have had a significant warming effect in addition to their other known effects on radiation.

In addition to centennial-scale temperature shifts, the existence of numerous temperature maxima between 2200 and 250 years BP (average ???70 years) suggests that multi-decadal processes typical of the North Atlantic Oscillation (NAO) are an inherent feature of late Holocene climate. However, late 19th and 20th century temperature extremes in Chesapeake Bay associated with NAO climate variability exceeded those of the prior 2000 years, including the interval 450-1000 AD, by 2-3??C, suggesting anomalous recent behavior of the climate system. ?? 2002 Elsevier Science B.V.

    Recent estimates of the contribution of glaciers to sea-level rise during the 20th century are strongly divergent. Advances in data availability have allowed revisions of some of these published estimates. Here we show that outside of Antarctica, the global estimates of glacier mass change obtained from glacier-length-based reconstructions and from a glacier model driven by gridded climate observations are now consistent with each other, and also with an estimate for the years 2003-2009 that is mostly based on remotely sensed data. This consistency is found throughout the entire common periods of the respective data sets. Inconsistencies of reconstructions and observations persist in estimates on regional scales.

    The role mathematics plays within physics has been of sustained interest for physicists as well as for philosophers and historians of science. We explore this topic by tracing the role the mathematical structure associated with SU(2) has played in three key episodes in 20th century physics - intrinsic spin, isospin, and gauge theory and electroweak unification. We also briefly consider its role in loop quantum gravity. Each episode has led to profound and new physical notions of a space other than the traditional ones of space and spacetime, and each has had associated with it a complex and in places, contested history. The episodes also reveal ways mathematical structures provide resources for new physical theorizing and we propose our study as a contribution to a need Roger Penrose has identified to develop a 'profoundly sensitive aesthetic' sense for locating physically relevant mathematics.

  13. Did 20th century physics have the means to reveal the nature of inertia and gravitation?

    At the beginning of the 20th century the classical electron theory (or, perhaps more appropriately, the classical electromagnetic mass theory) - the first physical theory that dared ask the question of what inertia and mass were - was gaining momentum and there were hopes that physics would be finally able to explain their origin. It is argued in this paper that if that promising research path had not been inexplicably abandoned after the advent of relativity and quantum mechanics, the contemporary physics would have revealed not only the nature of inertia, mass, and gravitation, but most importantly would have outlined the ways of their manipulation. Another goal of the paper is to try to stimulate the search for the mechanism responsible for inertia and gravitation by outlining a research direction, which demonstrates that the classical electromagnetic mass theory in conjunction with the principle of equivalence offers such a mechanism.

    Sea ice is an important component in the Earth's climate system.Coupled climate system models are indispensable tools for the study of sea ice,its internal processes,interaction with other components,and projection of future changes.This paper evaluates the simulation of sea ice by the Flexible Global Ocean-Atmosphere-Land System model Grid-point Version 2 (FGOALS-g2),in the fifth phase of the Coupled Model Inter-comparison Project (CMIP5),with a focus on historical experiments and late 20th century simulation.Through analysis,we find that FGOALS-g2 produces reasonable Arctic and Antarctic sea ice climatology and variability.Sea ice spatial distribution and seasonal change characteristics are well captured.The decrease of Arctic sea ice extent in the late 20th century is reproduced in simulations,although the decrease trend is lower compared with observations.Simulated Antarctic sea ice shows a reasonable distribution and seasonal cycle with high accordance to the amplitude of winter summer changes.Large improvement is achieved as compared with FGOALS-g1.0 in CMIP3.Diagnosis of atmospheric and oceanic forcing on sea ice reveals several shortcomings and major aspects to improve upon in the future:(1) ocean model improvements to remove the artificial island at the North Pole;(2) higher resolution of the atmosphere model for better simulation of important features such as,among others,the Icelandic Low and westerly wind over the Southern Ocean; and (3) ocean model improvements to accurately receive freshwater input from land,and higher resolution for resolving major water channels in the Canadian Arctic Archipelago.

  15. On the transformation of antique stories and images in German literature of the 20th century

    Full Text Available On the basis of analysis of Russian and foreign scholars, the work is aimed at studying the specificity of the transformation of antique stories and images, which is the desired model in the art of the 20th century thanks to its fluidity and unlimited variability. Actualization of antique stories and images in the works of German-language writers account for life-changing moments of social life, the periods of losing of constant moral landmarks and the periods of looking for new moral and aesthetic ideals. The analysis of the reception and transformation of mythological stories and images in the contemporary literature proves the conception of its polysemy. The built-in contradiction of myths is realized through the transformation of mythological stories and images in the literary works of contemporary writers and is explained by the individuality of writers and theirs aesthetic aims. On the one side, the absence de facto in German drama of the 20th century of interpretations of the story about Achilles and of the image of Achilles, and numerous variations on the topic of moral strivings of fearless and peccant Ulysses, on the other side, are proving the statements of classic aesthetic that the tragedy is based on the conflict, which is close to lofty and linked with the idea of dignity of the man, which is ready and capable of promoting the views of his own by the real acts that are often lead to suffer and death. According to Aristotle, the sympathy for the character leads to catharsis - the basis of education of real civic-mindedness and humanness.

    Full Text Available Cultural heritage institutions, archives, libraries and museums, which share the common goal of safeguarding and enabling wide accessibility to and use of cultural heritage, have developed in different but not diametrically opposing directions. Many scientists and practitioners from archival science, librarianship, museology and the wider area of information science have therefore studied, over many years, fundamental principles and characteristics of their activity and similarities and differences between these institutions and professions with the ultimate aim of discovering and describing potential models and guidelines for their coordinated action. First papers on this topic in the 20th century appeared in 1930s. Authors of these papers were most often librarians and archivists whose writing was initiated by their immediate working and professional environment. Based on the analysis and overview of accessible literature this paper presents and comments the thoughts of the author who was writing on this subject for over five decades, from 1930s to 1980s. These authors came, in most cases, from the United States of America and they dealt with similarities and differences between archives and libraries. Museum professionals joined this discussion only in 1960s by introducing specific characteristics and aspects of museums and museum work. In order to contribute to the understanding of interrelationships and evident convergence of these three cultural heritage institutions, which resulted in their mutual respect and in some cases with practical and active collaboration in particular in the modern networked society, the authors will try to present the development of theoretical and methodological thought on this phenomenon. The paper will provide a critical review of the most important authors who wrote on this topic from the first works that appeared through the last decade of the 20th century.

    Full Text Available Visual observations of clouds have been performed since the establishment of meteorological observatories during the early instrumental period, and have become more systematic and reliable after the mid-19th century due to the establishment of the first national weather services. During the last decades a large number of studies have documented the trends of the total cloud cover (TCC and cloudy types; most of these studies focus on the trends since the second half of the 20th century. Due to the lower reliability of former observations, and the fact that most of this data is not accessible in digital format, there is a lack of studies focusing on the trends of cloudiness since the mid-19th century. In the first part, this work attempts to review previous studies analyzing TCC changes with information covering at least the first half of the 20th century. Then, the study analyses a database of cloudiness observations in Southern Europe (Spain since the second half of the 19th century. Specifically, monthly TCC series were reconstructed since 1866 by means of a so-called parameter of cloudiness, calculated from the number of cloudless and overcast days. These estimated TCC series show a high interannual and decadal correlation with the observed TCC series originally measured in oktas. After assessing the temporal homogeneity of the estimated TCC series, the mean annual and seasonal series for the whole of Spain and several subregions were calculated. The mean annual TCC shows a general tendency to increase from the beginning of the series until the 1960s; at this point, the trend becomes negative. The linear trend for the annual mean series, estimated over the 1866–2010 period, is a highly remarkable (and statistically significant increase of +0.44% per decade, which implies an overall increase of more than +6% during the analyzed period.

    Public health nursing work has always involved education about nutrition and food habits. Nurses serve as interpreters of scientific and medical knowledge and as agents of behavioral change among the individuals and groups for whom they provide care. For public health nurses in mid-20th-century America, this meant direct involvement in many aspects of family life at home. Meal preparation and the eating patterns of family members were two areas into which most public health nurses had access. This brief history provides an introduction to some of the issues confronting American public health nurses at mid-century. Examining the content of articles related to nutrition in families around mid-century yields evidence about the role of the nurse, the state of the art in nutritional knowledge, and opinions and prejudices related to eating habits prevalent at the time. These glimpses into concerns expressed in the original Public Health Nursing journal may enhance understanding of the role of public health nurses in preventing diet-related disorders and form the basis for additional historical research.

    The IAP/LASG GOALS coupled model is used to simulate the climate change during the 20th century using historical greenhouse gases concentrations, the mass mixing ratio of sulfate aerosols simulated by a CTM model, and reconstruction of solar variability spanning the period 1900 to 1997. Four simulations,including a control simulation and three forcing simulations, are conducted. Comparison with the observational record for the period indicates that the three forcing experiments simulate reasonable temporal and spatial distributions of the temperature change. The global warming during the 20th century is caused mainly by increasing greenhouse gas concentration especially since the late 1980s; sulfate aerosols offset a portion of the global warming and the reduction of global temperature is up to about 0.11°C over the century; additionally, the effect of solar variability is not negligible in the simulation of climate change over the 20th century.

  2. Reconstructing 20th Century Summer Precipitation on the South-Central Tibetan Plateau

    The Tibetan Plateau has experienced significant increases in temperature over the 20th century, but trends in precipitation are less clear, as station precipitation records are sparse and satellite observations only extend back to 1979. Here we use the sediment record from Ngamring Co, a closed-basin, freshwater lake in south-central Tibet, to assess summer precipitation over the last century. Ngamring Co is located in a watershed without glaciers, so recent changes in runoff and lake level are independent of the influence of glacial ice volume. The first principal component of the Ngamring Co grain size dataset is highly correlated with median grain size and covaries significantly with local July-August precipitation from the CPC Merged Analysis of Precipitation (CMAP). From 1979 to 2007, median grain size decreases with increasing July-August precipitation and increases with decreasing July-August precipitation. There is prominent multidecadal variability in the 20th century grain size record, including a gradual decline in median grain size from 1900 to 1930, a gradual increase in median grain size from 1930 to 1990, and a rapid decline in median grain size since 1990. Median grain size values from 2000-2007 are the lowest in the 107-year record, suggesting the most abundant monsoon precipitation in the last 107 years has occurred in the last decade. Satellite images of the lake also confirm an increase in lake area since the early 1990s, but also show the greatest lake area occurred in the 1970s. Thus, although summer precipitation and lake area do covary, precipitation does not seem to control grain size by influencing lake area. We presently hypothesize that increased July-August precipitation causes enhanced erosion of the fine-grained sediment (likely paleolake sediments and loess) that blankets the slopes surrounding the lake. The ensuing runoff and deposition of this sediment into the lake then results in a decline in median grain size within the lake

    Unlike in the North Atlantic, no continuous record of anthropogenic lead (Pb) has been available in the western Pacific. We reconstructed historical changes in anthropogenic Pb on the basis of Pb isotope ratios recorded in annually-banded coral retrieved from Ogasawara Island, Japan. Whereas the predominant natural source of Pb to the surface of the western Pacific apparently is Chinese loess, anthropogenic Pb has affected the western Pacific at least since the late 19th century. From the late 19th to the early 20th century, Australian Pb used in Japan was an important source of anthropogenic Pb. During 1920-1940, Pb emitted from parts of the world other than Japan contributed somewhat to the western Pacific, and the amount of Pb imported from Australia declined. Alkyl Pb used in Japan became the main source from 1950 until the mid-1970s, when leaded gasoline began to be regulated in Japan. Since the mid-1980s, aerosols from China have been the predominant source of Pb in the western Pacific. During the 1990s, around 60% of Pb in the surface of the western Pacific was from Chinese aerosols. We also investigated the present spatial distribution and likely sources of Pb in the western Pacific by using coral samples. Enrichment in {sup 208}Pb, which is a characteristic of Pb from China, was found in all coral samples except that from Pohnpei, Micronesia, suggesting that at present anthropogenic Pb is transported to the western Pacific mainly from China via westerly winds.

    Full Text Available The following paper talks about the formation, urban expansion and the emergence of 19th and early 20th century slums at Pelotas city, Rio Grande do Sul state. Since the rise of this kind of residential building, during the second half of the 19th century up to, at least, the 1920s – the last decade covered by this research – government and local elites had been putting a great effort in order to move away these residences towards the outskirts of the city. All of this ideas were paved around hygienist ideals. Lots and edifications in downtown Pelotas had an increase in economic value because of the expansion of that area. That being said, it was important to force a migration of these slums, away from central areas, based upon aesthetic reasons and in order to increase even more the value of the area.

    Pollock, Warhol, Basquiat and Haring made an international reputation for themselves with their art foremost of the American artists of the 20th century, and became pop cultural icons for the man in the street and for the media as well. Accordingly to the habits of the consumer society their art and even themselves become product and consumer's goods. Their not mistaken, individual style - which also became their trademark - makes that possible. The connection between the four artists is that each of them had a dependent personality, their fine art activity was arguable in their period, and after all themselves and his artworks get into the increased attention of the media. These four artists embody the brand-new artist type, who steps into a star status. Besides the artworks the artist also get into the focus of interest. Through psychological aspect their artworks tell a lot about their way of life, their personality, and the social estate around them. Four of them were catalysts, they set new art trends. The influence of Basquiat and Haring stretched over to the 21st century, and keeps going in the graffiti street-art which gets into the "high art" at last, and captivates the art galleries and critics as well.

  7. From posters to displaying: poster communication in Osijek in the early 20th century

    Full Text Available There are many monographs, articles, chapters and exhibitions and their catalogues dedicated to Croatian posters from the early 20th century. Posters are evaluated as works of art, but received very little attention as an advertising medium. Their communication and advertising role in the specified time and place has not been investigated thoroughly. This paper does not investigate the relationship between the artistic and marketoriented aspects of posters, neither does it evaluate which and what type of posters deserve to be considered works of art. It focuses on how and where did people in the early 20th century used posters to inform themselves about new events and products. Posters are viewed only as a communicative and promotion medium, and the place where they were displayed as a sort of an information hub.The authors investigate the possibility of using two types of historical resources: city administration documents that regulated the displaying of posters and different pictures - like postcards, newspaper photos showing current events, posters and notice-boards or columns. The city of Osijek is selected as a case study for this approach. As the appropriation of posters is determined by their content, graphic design and place where they are displayed, the aim of the paper is to investigate the possible resources that can help us reconstruct the procedures and locations for poster displays. Following the methodology proposed by Robert Darnton, who listed five possible approaches to investigating different texts, and by Roger Chartier’s papers in which he stresses the importance of content appropriation, i.e. the subjectivity of readers, and not the de-contextualized content itself, the authors propose a step from posters to displaying them - or advertising - in public places in the city.Analyzing the above stated sources it can be established that there was a demand for the public advertising space in Osijek in the early 20th century

    New focus on the internationalization of universities occurred in the late 20th century and higher education in nursing has been quick to embrace the opportunities. In this manuscript, writers provide a brief overview of the nursing and more general literature from the late 20th century relating to key dimensions of internationalization, as well as present data from a survey conducted in 1995-96 of the international activities and dimensions at Canadian faculties/schools of nursing. While it is clear that nurses in Canadian universities were engaged in significant international endeavours in the 20th century, the literature and our experience suggest that the extent of such activity has increased substantially in recent years. Discussion centres on examination of how knowledge generated in the 20th century can inform current internationalization initiatives and on identification of key questions that merit consideration as we move forward in the 21st century.

    Santorini, the famous stratovolcano in the Aegean Sea, erupted three time periods during the 20th century (1925-1928, 1939-1941, 1950) and since then remains dormant. This study tried to combine and evaluate new and published volcanological, petrological, geochemical, environmental and sociological data of these three phases of Santorini's activity, which practically restricted to the caldera center on the Nea Kameni Islet. After field work on the formed dacite flows, pyroclastics and domes, representative rock samples and enclaves were collected and investigated for their texture, physical parameters, mineralogy and chemical composition by polarizing light microscope, scanning electron microscope (SEM-EDS), XRD, Raman spectroscopy and ICP-MS. The petrogenetic evaluation of the data obtained suggests slight but significant changes in the solid and aerial phases produced during the three explosion stages, which can be attributed to minor variations in the magmatic differentiation and magma chamber physicochemical conditions. These variations were also expressed by decrease of duration and intensity of the eruptions, as well as in their volume of ejecta and lava. Probably, the subsequent relatively long dormant period of the volcano is also related to this tension of decrease. The first compared results were collected from scientific literature, old photos as well as local and regional press and state documents from the different periods of volcanism, record the past hazard case scenarios and civil defense planning of the individual eruptions. As part of the disaster management a pilot survey, in which personal interviews with aged local islanders that were eye-witnesses of the events and elderly people or tourists that they indirectly experienced or have heard about them, was also conducted. This event-tracing, along with air pollution software models using volcanological data have shown the social impacts and the environmental consequences of the volcanic

    In 2002, Munk defined an important enigma of 20th century global mean sea-level (GMSL) rise that has yet to be resolved. First, he listed three canonical observations related to Earth's rotation [(i) the slowing of Earth's rotation rate over the last three millennia inferred from ancient eclipse observations, and changes in the (ii) amplitude and (iii) orientation of Earth's rotation vector over the last century estimated from geodetic and astronomic measurements] and argued that they could all be fit by a model of ongoing glacial isostatic adjustment (GIA) associated with the last ice age. Second, he demonstrated that prevailing estimates of the 20th century GMSL rise (~1.5 to 2.0 mm/year), after correction for the maximum signal from ocean thermal expansion, implied mass flux from ice sheets and glaciers at a level that would grossly misfit the residual GIA-corrected observations of Earth's rotation. We demonstrate that the combination of lower estimates of the 20th century GMSL rise (up to 1990) improved modeling of the GIA process and that the correction of the eclipse record for a signal due to angular momentum exchange between the fluid outer core and the mantle reconciles all three Earth rotation observations. This resolution adds confidence to recent estimates of individual contributions to 20th century sea-level change and to projections of GMSL rise to the end of the 21st century based on them.

  11. THE POPULATION’S NOMINAL AND REAL INCOMES IN ROMANIA IN THE 20TH CENTURY

    Full Text Available The research of Romania’s population incomes for a period of a century has not only an incontestable historical importance, but also a social one, as it may give answer to the question what was gained from the viewpoint of the living standard of the population in the 20th century. The issue is approached under two aspects of the economic and social polarisation process, and of the real incomes, and also with respect to the capacity of comparing the main population categories. The differing purposes of the social and ideological systems underwent during this century, and the periods of war and destruction have both triggered a sinuous incomes’ curve with considerable raises and falls of incomes. The final conclusion is that the level of average incomes from 1914 is re-established in the aftermath of the First World War only about 1929, and the year 1938 is situated beneath the pre-crises threshold. World War II and the crisis following it have diminished average incomes to 20 - 25% from the level of the year 1938 and only after 1970 the pre-war threshold is reached again, which is followed in the eighties and nineties by significant growth to be brutally annulled by the transition processes up to 2000, when the average real income is again at the level of the year 1970. It results that the development efforts of six decades, 1939-2000, from the viewpoint of incomes’ level were lost for the majority of the country’s population in favour of a minority that was made rich by the transition.

    by bedrock geometry. It is revealed that dynamic ice loss recently seen in the southeast and northwest GrIS also occurred in the northwest between 1985 and 1993, highlighting the difficulty of capturing these events in mass balance models. Extending the record back to the LIA, the results show...... that for the past 110 years, the surface mass balance has been decreasing, while the dynamic term has been constant. The spatial pattern of thinning in the 20th century is identical to that of current change, suggesting this pattern will continue in the near future. The mass change of the GrIS in 20th century...

    This paper presents the results of the dental analysis performed on a Khoesan skeletal sample representing the late 19th and early 20th century Cape Colony in southern Africa. Skeletal material from two European collections (Vienna and Paris) was selected to compile a total sample of 116 specimens. Dental pathology frequencies were calculated for caries (28.4%), antemortem tooth loss (37.9%), periapical abscesses (29.3%), periodontal disease (26.7%), calculus (44.0%) and impacted canines (4.3%). Attrition scores indicated that the group under study had an average rate of attrition compared to other southern African populations. Frequency and intensity data were compared to several other samples from both the pre-contact and contact phases by means of chi-squared analysis. The outcome of the study suggested that the group under study was most likely in a state of transition between a diet and lifestyle of hunting-and-gathering and agriculture. Results were also consistent with those of groups from a low socio-economic status. PMID:25882044

  15. High-resolution record of pyrogenic polycyclic aromatic hydrocarbon deposition during the 20th century.

    2003-01-01

    A high-resolution record of polycyclic aromatic hydrocarbon (PAH) deposition in Rhode Island over the past approximately 180 years was constructed using a sediment core from the anoxic Pettaquamscutt River basin. The record showed significantly more structure than has hitherto been reported and revealed four distinct maxima in PAH flux. The characteristic increase in PAH flux at the turn of the 20th century was captured in detail, leading to an initial maximum prior to the Great Depression. The overall peak in PAH flux in the 1950s was followed by a maximum that immediately preceded the 1973 Organization of Petroleum Exporting Countries (OPEC) oil embargo. During the most recent portion of the record, an abrupt increase in PAH flux between 1996 and 1999 has been found to follow a period of near constant fluxes. Because source-diagnostic ratios indicate that petrogenic inputs are minor throughout the record, these trends are interpreted in terms of past variations in the magnitude and type of combustion processes. For the most recent PAH maximum, energy consumption data suggest that diesel fuel combustion, and hence traffic of heavier vehicles, is the most probable cause for the increase in PAH flux. Systematic variations in the relative abundance of individual PAHs in conjunction with the above changes in flux are interpreted in relation to the evolution of combustion processes. Coronene, retene, and perylene are notable exceptions, exhibiting unique down-core profiles. PMID:12542290

    Full Text Available In spite of being a historic constant and a characteristic phenomenon of the 20th century, the subject ‘exile’ is still little valued by contemporary historiography´. The civil war from 1936 to 1939 and the Francoist triumph provoked an exile without precedent in recent Catalonian history. This exile was decisive in the preservation of Catalan culture (persecuted by the Franco regime in Catalonia itself, as well as for the continuity of Catalan self-government, the ‘Generalitat of Catalonia’. It was also an extremely important platform for the democratic opposition to Francoism, although it lost its political weight around the nineteen sixties. At that time, though, new waves of exiles took place caused by the fight against the dictatorship, but they were in no way related to the scale of those from the civil war in the thirties. At the dictator’s death many people returned home, but the fragility of the democracy born from the political transition process brought new exiles. In order to know more in detail on such an important subject it is necessary to promote a culturally institutionalised process that makes possible its systematic study, and it is also necessary that the analysis of this phenomenon become a top priority aim of study for historiography and for all human sciences.

  17. Einstein and early 20th Century avant-garde art: points of contact?

    CERN Document Server

    Martini, José X

    2007-01-01

    Art history linked some early 20th Century avant-garde visual art movements to contemporary systems of ideas in mathematics and theoretical physics. One of the proposed connections is the one that might have existed between Cubism and Relativity, or more precisely, between Picasso and Einstein. The suggested links are similarity (in a weak version) or identity (in a strong version) in matters of space, time and simultaneity. It is possible, however, that these supposed links of Einstein and avant-garde art movements were more the product of the imagination of historians and critics, than the result of connections between painters and scientists. On the one hand, the visual arts (in contrast to music, as far as we now) were of no interest to Einstein, who, moreover, did not seem inclined or knowledgeable enough to appreciate advanced forms. On the other hand, Einstein's theories fell outside the artists' ken, let alone their understanding, although there are firm clues pointing to the fact that repercussions o...

    2003-01-01

    We have used numerical models to test the impact of the change in Sea Surface Temperatures (SSTs) and carbon dioxide (CO2) concentration on the global circulation, particularly focusing on the hydrologic cycle, namely the global cycling of water and continental recycling of water. We have run four numerical simulations using mean annual SST from the early part of the 20th century (1900-1920) and the later part (1980-2000). In addition, we vary the CO2 concentrations for these periods as well. The duration of the simulations is 15 years, and the spatial resolution is 2 degrees. We use passive tracers to study the geographical sources of water. Surface evaporation from predetermined continental and oceanic regions provides the source of water for each passive tracer. In this way, we compute the percent of precipitation of each region over the globe. This can also be used to estimate precipitation recycling. In addition, we are using the passive tracers to independently compute the global cycling of water (compared to the traditional, Q/P calculation).

    Full Text Available This study presents linear trends of coastal upwelling intensity in the later part of the 20th century (1960–2001 employing various indices of upwelling, derived from meridional wind stress and sea surface temperature. The analysis was conducted in the four major coastal upwelling regions in the world, which are off North-West Africa, Lüderitz, California and Peru respectively. The trends in meridional wind stress showed a steady increase of intensity from 1960–2001, which was also reflected in the SST index calculated for the same time period. The steady cooling observed in the instrumental records of SST off California substantiated this observation further. Correlation analysis showed that basin-scale oscillations like the Atlantic Multidecadal Oscillation (AMO and the Pacific Decadal Oscillation (PDO could not be directly linked to the observed increase of upwelling intensity off NW Africa and California respectively. The relationship of the North Atlantic Oscillation (NAO with coastal upwelling off NW Africa turned out to be ambiguous due to a negative correlation between the NAO index and the meridional wind stress and a lack of correlation with the SST index. Our results give additional support to the hypothesis that the coastal upwelling intensity increases globally because of raising greenhouse gas concentrations in the atmosphere and an associated increase of the land-sea pressure gradient and meridional wind stress.

    Oumar Faye

    Full Text Available Zika virus (ZIKV is a mosquito-borne flavivirus first isolated in Uganda in 1947. Although entomological and virologic surveillance have reported ZIKV enzootic activity in diverse countries of Africa and Asia, few human cases were reported until 2007, when a Zika fever epidemic took place in Micronesia. In the context of West Africa, the WHO Collaborating Centre for Arboviruses and Hemorrhagic Fever at Institut Pasteur of Dakar (http://www.pasteur.fr/recherche/banques/CRORA/ reports the periodic circulation of ZIKV since 1968. Despite several reports on ZIKV, the genetic relationships among viral strains from West Africa remain poorly understood. To evaluate the viral spread and its molecular epidemiology, we investigated 37 ZIKV isolates collected from 1968 to 2002 in six localities in Senegal and Côte d'Ivoire. In addition, we included strains from six other countries. Our results suggested that these two countries in West Africa experienced at least two independent introductions of ZIKV during the 20(th century, and that apparently these viral lineages were not restricted by mosquito vector species. Moreover, we present evidence that ZIKV has possibly undergone recombination in nature and that a loss of the N154 glycosylation site in the envelope protein was a possible adaptive response to the Aedes dalzieli vector.

    2014-09-01

    Full Text Available The article reveals the peace-making ideas of famous historian, sociologist and lawyer M.M. Kovalevsky at the beginning of 20th century and analyzes the sociological conception of solidarity which served as the basis for his views on war and peace. He considered social progress as broadening of solidarity sphere which was unavoidably promoted to the consciousness of political integration society. The scientist approximately compared the progress with concentric circles which embodied of uninterruptedly widing human solidarity. The final stage of social and political development should be the creation of national and federal unions, which in their turn would unify in international union. The union built on the principles of democracy and observance of international right standards was destined not only to keep and to ensure the common peace, but also to promote the development of international trade and industry. Kovalevsky played important role in building the peace-making movement in Russia by supporting it with his high scientific and moral authority. In particular, he headed the St. Petersburg’s peace society, established in 1909. Besides, there were a lot of contradictions in his peaceful views. Being the patriot and supporter of the state, the scientist was very far from peace when Russian national interests were taken ino account. This contradiction was clearly revealed during Balkan’s conflict (1912-1913 and the First World War.

    Full Text Available Pedagogy in Slovenia gradually won its recognition as an academic science, and therefore obtained improved possibilities for its conceptualization, when the university in Ljubljana was established in 1919. The time between the two world wars was marked with three principal pedagogical concepts: Herbartianism, geisteswissenschaftliche pedagogy, and reform pedagogy. The first of these to be theoretically conceptualized in Slovenia was the geisteswissenschaftliche, or cultural pedagogy. Ideas of reform pedagogy, especially its social-critical movement, interpreted, represented, and defended primarily left-oriented pedagogues and teachers, who were convinced that actual school reform would be possible only after (revolutionary changes of social conditions. In the first decades of the 20th century, numerous conflicts and disagreements occurred in the process of establishing individual pedagogical currents and orientations in Slovenia. The strongest and most productive polemics were held between geisteswissenschaftliche, or cultural pedagogy, and some currents, or just individual representatives, of reform pedagogy (e.g., theory vs. praxis, old vs. new school. Unfortunately, the postwar Marxist pedagogical concept was highly unfavorable to the prewar orientations and prevented their further development.

    Full Text Available The article analyzes the development of agriculture and trade relations in the Caucasus in the early 20th century. This article utilizes the records of Georgian national archives, pre-revolutionary periodicals and monographic literature published in pre-revolutionary, soviet and Russian contemporary periods. The authors used the research methods such as principles of objectivity, historicism, systematic, comprehensive accounting of the economic indicators of agriculture development and trade in the Caucasus and the maximum possible neutrality of the researcher to interpret factual material. The authors come to the conclusion that the development of agriculture in the Caucasus after the revolutionary upheavals of 1905-1907 years in the subsequent period before the First World War entered into the stage of recovery. The reasons of this phenomenon became the discovery of significant quantities of oil, cement, manganese and other fields. The objects of the industry demanded also the additional food supply, this enabled the agriculture in the Caucasus to develop actively.

We constructed a network of 13 PEB records with excess 210Pb-derived chronologies to establish the development of low-oxygen and hypoxic conditions over a large portion of the modern dead zone for the last 100 years. The PEB index record indicates that areas of low-oxygen bottom water began to appear in the early 1910s in isolated hotspots near the Mississippi Delta and rapidly expanded across the entire Louisiana shelf beginning in the 1950s. Since ???1950, the percentage of PEB species has steadily increased over a large portion of the modern dead zone. By 1960, subsurface low-oxygen conditions were occurring seasonally over a large part of the geographic area now known as the dead zone. The long-term trends in the PEB index are consistent with the 20th-century observational and proxy data for low oxygen and hypoxia. ?? 2009 US Government.

    Full Text Available In this article, we introduce a new algorithm called randomised multichannel singular spectrum analysis (RMSSA, which is a generalisation of the traditional multichannel singular spectrum analysis (MSSA into problems of arbitrarily large dimension. RMSSA consists of (1 a dimension reduction of the original data via random projections, (2 the standard MSSA step and (3 a recovery of the MSSA eigenmodes from the reduced space back to the original space. The RMSSA algorithm is presented in detail and additionally we show how to integrate it with a significance test based on a red noise null-hypothesis by Monte-Carlo simulation. Finally, RMSSA is applied to decompose the 20th century global monthly mean near-surface temperature variability into its low-frequency components. The decomposition of a reanalysis data set and two climate model simulations reveals, for instance, that the 2–6 yr variability centred in the Pacific Ocean is captured by all the data sets with some differences in statistical significance and spatial patterns.

  7. Language & authoritarianism in the 20th century: The cases of Estonia and Catalonia

    Directory of Open Access Journals (Sweden)

    Delaney Michael Skerrett

    2010-05-01

    Full Text Available The 20th century saw the Soviet and Francoist regimes enforce their respective ideologies in Estonia and the Catalan-speaking territories in Spain. In both cases, the autochthonous language suffered under the stringent control of the mechanisms of censorship and repression. In fact, Soviet and Spanish leaders—representing both extremes of the political spectrum—tried to replace the use of the autochthonous language in many sociolinguistic domains with their own—Russian and (Castilian Spanish—as these languages embodied the ideologies and the new orders that they wished to establish. This paper compares and contrasts the diverse methods of control over language carried out in Estonia and the Catalan-speaking areas of Spain in order to demonstrate that highly centralised multilingual states—whatever their political ideology—can make use of surprisingly similar means of control, ultimately depriving local linguistic communities of the ability to use and develop their own language.DOI: http://dx.doi.org/10.5128/ERYa6.16

    René Leriche (1879-1955) was a 20(th) century French surgeon generally known in medicine for the syndrome that carries his name, namely the Leriche syndrome in the aorto-iliac occlusive disease. This paper is published to mark the commemoration of 60 year since Leriche's death. Although Dr. Leriche's legacy resides in the domain of vascular medicine, his research enclosed bone pathology and surgical management of pain. Having his surgical training done under professors Mathieu Jaboulay and Antonin Poncet, his friendship and association with Alexis Carrel and William Halsted have contributed to René Leriche's development as a surgeon, researcher and thinker. Following the footsteps of his mentors, he produced outstanding clinical and academic work which had earned him a good reputation among his students and colleagues. Surgeons such as Jean Kunlin, Jao Cid dos Santos, Michael DeBakey, René Fontaine and others came to study and learn from him. These future generations of surgeons would themselves bring much contribution to the understanding and treatment of vascular diseases and medicine in general. René Leriche pioneered medicine with his research and ideas. His assiduous work of teaching, research and clinical practice made his influence last to our present. PMID:27004042

    Lens and cataract research from a clinical, biophysical, biological and mainly biochemical point of view has a long tradition. Already since the beginning of the 20th century research relating to the chemical composition and metabolism of the lens was conducted. With these analyses an attempt was made to understand the existence and maintenance of lens transparency and the mechanisms leading to lens opacities. Around the middle of the century the stationary analyses measuring the content of certain substances in the lens were more and more replaced by the search for dynamic metabolic processes responsible for lens growth, maintenance of transparency and possibly active participation in lens function (such as accommodation). Also the disturbances as a result of ageing or the formation of lens opacities have been investigated and resulted partially in the elucidation of reaction chains, leading from a trigger to the formation of a cataract. Lens biochemistry is no longer a closed book to us, but there are still many question marks. Why were we not able to solve more problems around lens and cataract? The research effort with a remarkable financial input and a great number of scientists worldwide during the second half of the century does not correspond to the results obtained. There must be something wrong with our strategy, our interpretation of the results or even both. We would like to stress some points which might be regarded as errors or misunderstandings in the lens research community, thus preventing a better outcome of the enormous investment of work and money. A great disadvantage is the missing cooperation between clinicians and epidemiologists on one hand and basic lens researchers on the other. Especially the ignorance of basic researchers regarding the clinical problems of the lens and of cataracts might be to blame for several 'errors and misunderstandings'. It is not even so long ago since the slitlamp microscope examination of animals belonged to the

    The historical reanalysis dataset generated by NOAA ESRL and the University of Colorado CIRES, the Twentieth Century Reanalysis version 2 (20CRv2), is a comprehensive global atmospheric circulation dataset spanning 1871-2012, assimilating only surface pressure and using monthly Hadley Centre SST and sea ice distributions (HadISST1.1) as boundary conditions. It has been made possible through collaboration with GCOS, WCRP, and the ACRE initiative. It is chiefly motivated by a need to provide an observational validation dataset, with quantified uncertainties, for assessments of climate model simulations of the 20th century, with emphasis on the statistics of daily weather. It uses, together with an NCEP global numerical weather prediction (NWP) land/atmosphere model to provide background "first guess" fields, an Ensemble Kalman Filter (EnKF) data assimilation method. This yields a global analysis every 6 hours as the most likely state of the atmosphere, and also yields the uncertainty of that analysis. Improvements in the new version ("2c") include an extension back to 1850 and the specification of new boundary conditions. These come from new fields of monthly COBE-SST2 sea ice concentrations and an ensemble of daily Simple Ocean Data Assimilation with Sparse Input (SODAsi.2c) sea surface temperatures. SODAsi.2c itself was forced with 20CR, allowing these boundary conditions to be more consistent with the atmospheric reanalysis. Millions of additional pressure observations contained in the new International Surface Pressure Databank version 3 are also included. These improvements result in 20CR version "2c" having comparable or better analyses, as suggested by improved 24 hour forecast skill, more realistic uncertainty in near-surface air temperature, and a reduction in spurious centennial trends in the tropical and polar regions. An intercomparison with ERA-Interim, MERRA, and JRA-55 reanalyses that assimilate all available upper-air and satellite observations will

    Construction of Canada’s Dominion Astrophysical Observatory (DAO) commenced in 1914 with first light on 6 May 1918. Its varied, rich contributions to the astronomical heritage of the 20th century continue into the 21st century. The first major research observatory built with public funding on the West Coast of North America, it was Canada’s first ‘big science’ project. DAO welcomed scientists from around the world to use its 1.8m telescope designed by John Stanley Plaskett working in close collaboration with the Warner and Swasey Company of Cleveland, OH. Their original design was copied seven times around the globe, the last occasion being in the 1960s. From Day 1 the DAO welcomed the public for viewing and interaction with the small scientific staff whose early efforts would today be characterized as ‘Key Projects’. Those efforts included measuring the radial velocities of O and B stars that, interpreted through Oort’s ideas of differential rotation, determined the most reliable estimate of the size and mass of the Milky Way available until radio astronomical techniques emerged in the 1950s. The first organic molecule in interstellar space, CH, was discovered by a DAO astronomer. The first, very puzzling estimate of ~3K for the temperature of interstellar space was deduced from interstellar CN observations a year after interstellar CH and CN were discovered. DAO’s heritage of innovative instrumentation continues to the present day where expertise in optically efficient, mechanically stable spectrographs and adaptive optics are much in evidence at Mauna Kea’s CFHT, Gemini and Subaru observatories. In 2009 the DAO was designated a National Historic Site. This presentation will draw links between DAO, developments of Canadian astronomy and the emergence of Mauna Kea as an exceptional global astronomical reserve.

    The present paper describes the main results obtained from the characterization of a wide range of natural and synthetic ochre samples used in Portugal from the 19th to the 20th century, including powder and oil painting samples. The powder ochre samples came from several commercial distributors and from the collection of Joaquim Rodrigo (1912-1997), a leading Portuguese artist, particularly active during the sixties and seventies. The micro-samples of oil painting tubes came from the Museu Nacional de Arte Contemporânea-Museu do Chiado (National Museum of Contemporary Art-Chiado Museum) in Lisbon and were used by Columbano Bordalo Pinheiro (1857-1929), one of the most prominent naturalist Portuguese painters. These tubes were produced by the main 19th century colourmen: Winsor & Newton, Morin et Janet, Maison Merlin, and Lefranc. The samples have been studied using μ-Fourier Transform Infrared Spectroscopy (μ-FTIR), Raman microscopy, μ-Energy Dispersive X-ray fluorescence (μ-EDXRF), and X-ray diffraction (XRD). The analyzed ochres were found to be a mixture of several components: iron oxides and hydroxides in matrixes with kaolinite, gypsum and chalk. The results obtained allowed to identify and characterize the ochres according to their matrix and chromophores. The main chromophores where identified by Raman microscopy as being hematite, goethite and magnetite. The infrared analysis of the ochre samples allowed to divide them into groups, according to the composition of the matrix. It was possible to separate ochres containing kaolinite matrix and/or sulfate matrix from ochres where only iron oxides and/or hydroxides were detected. μ-EDXRF and Raman were the best techniques to identify umber, since the presence of elements such as manganese is characteristic of these pigments. μ-EDXRF also revealed the presence of significant amounts of arsenic in all Sienna tube paints.

    Switzerland has experienced a number of severe precipitation events during the last few decades, such as during the 14-16 November of 2002 or during the 21-22 August of 2005. Both events, and subsequent extreme floods, caused fatalities and severe financial losses, and have been well studied both in terms of atmospheric conditions leading to extreme precipitation, and their consequences [e.g. Hohenegger et al., 2008, Stucki et al., 2012]. These examples highlight the need to better characterise the frequency and severity of flooding in the Alpine area. In a larger framework we will ultimately produce a high-resolution data set covering the entire 20th century to be used for detailed hydrological studies including all atmospheric parameters relevant for flooding events. In a first step, we downscale the aforementioned two events of 2002 and 2005 to assess the model performance regarding precipitation extremes. The complexity of the topography in the Alpine area demands high resolution datasets. To achieve a sufficient detail in resolution we employ the Weather Research and Forecasting regional climate model (WRF). A set of 4 nested domains is used with a 2-km resolution horizontal resolution over Switzerland. The NCAR 20th century reanalysis (20CR) with a horizontal resolution of 2.5° serves as boundary condition [Compo et al., 2011]. First results of the downscaling the 2002 and 2005 extreme precipitation events show that, compared to station observations provided by the Swiss Meteorological Office MeteoSwiss, the model strongly underestimates the strength of these events. This is mainly due to the coarse resolution of the 20CR data, which underestimates the moisture fluxes during these events. We tested driving WRF with the higher-resolved NCEP reanalysis and found a significant improvement in the amount of precipitation of the 2005 event. In a next step we will downscale the precipitation and wind fields during a 6-year period 2002-2007 to investigate and

    Landscape spatial pattern mainly refers to the distribution of patches, which are different in size and shape in space owing to the interaction of various ecological activities. In landscape ecology study, landscape pattern has been one of the key study areas. Water body landscape plays an important role in the development history of a city, but at present city water body landscape in many cities has been destroyed, hence protecting water body in the city is becoming more and more important. In order to protect city water body landscape reasonably, the precondition is to probe the dynamics of water body landscape. Based on historical data and remote sensing data, six indexes including patch number, patch area, landscape dominance index, fractal dimension, patch density and connectivity index etc. were used to analyze landscape pattern dynamics of water body in Kaifeng city since the end of the Qing Dynasty (in the 20th century). The results showed: (1) Since the end of the Qing Dynasty, landscape area of water body in Kaifeng city increased first and then decreased from 1898 to 2002AD; the landscape dominant degree had the same changing tendency with the area. (2) Patch number of water body landscape in Kaifeng city had an increase from 1898 to 2002, but maximum area of patch, minimum area of patch and average area of patch decreased, which resulted in an increase in landscape fragment degree. (3) Connectivity index decreased and fractal dimension increased from 1898 to 2002. The reasons for these changes were the repeated overflows and flooding of the Yellow River and the influence of human activities.

    Geological, paleontological and geomorphologic studies show that the Earth's climate has always been changing since it came into existence. The climate change itself is self-evident. Therefore the far more serious question is how much does mankind strengthen or weaken these changes beyond the natural fluctuation and changes of climate. The aim of the present study was to restore the historical land cover changes and to simulate the meteorological consequences of these changes. Two different land cover maps for Hungary were created in vector data format using GIS technology. The land cover map for 1900 was reconstructed based on statistical data and two different historical maps: the derived map of the 3rd Military Mapping Survey of the Austro-Hungarian Empire and the Synoptic Forestry Map of the Kingdom of Hungary. The land cover map for 2000 was derived from the CORINE land cover database. Significant land cover changes were found in Hungary during the 20th century according to the examinations of these maps and statistical databases. The MM5 non-hydrostatic dynamic model was used to further evaluate the meteorological effects of these changes. The lower boundary conditions for this mesoscale model were generated for two selected time periods (for 1900 and 2000) based on the reconstructed maps. The dynamic model has been run with the same detailed meteorological conditions of selected days from 2006 and 2007, but with modified lower boundary conditions. The set of the 26 selected initial conditions represents the whole set of the macrosynoptic situations for Hungary. In this way, 2×26 "forecasts" were made with 48 hours of integration. The effects of land cover changes under different weather situations were further weighted by the long-term (1961-1990) mean frequency of the corresponding macrosynoptic types, to assume the climatic effects from these stratified averages. The detailed evaluation of the model results were made for three different meteorological

    Water quality in surface waters is influenced by watershed climate, hydrology, land cover and land use. Inputs from anthropogenic sources, such as fertilizers, wastewater and livestock, can greatly degrade water quality as they are transferred into surface water bodies. It is important to quantify the rate and severity of this transformation in order to minimize water quality damages to water resources. Additionally, throughout the 20th century, land use practices have constantly shifted with technological advancements and increases in population. Export coefficient models are useful regional scale models, which can address non-point pollution sources; however, such models only address land use practices without regard for other inputs to the hydrologic system. While physical models can model the relationships between the hydrologic system, human activities and water quality, such models are complex to develop and only apply to localized areas. Our primary goal is to quantify and characterize the trends in total nitrogen, total phosphorus and BOD loading into surface waters in the Northeast Corridor of the US from 1920-2000. The models combine features of export coefficient models and physical models using streamflow, climate, land use and anthropogenic inputs. Models are developed for 26 watersheds across the Northeast Corridor, which have over 10 years of water quality data. These models are representative of a wide range of land use types and thus may be applied to HUC 8 watersheds within the region. The resulting models describe how land use practices and the hydrologic system have affected water quality for this time period. Cross validation methods are employed to test and evaluate the resulting models.

    Full Text Available Plots reeled into the ekphrasis have always existed. In belles lettres of the beginning of the 20th century, the fight between the pagan and the Christian manifests in the opposition of scenic space and it creates a powerful «magnetic» field. This is a special type of mythologism in which the Christian imagery is on the positive side of the binary opposition with its respective system of ethical coordinates. In «polytheistic systems, the presentations of evil is static as of the essential and eternal beginning of the world», but in the orthodox Christianity, the devil is a ghost, lure, disembodied temptation and «with every day it approaches nonexistence» (from the «Moralia» of the 6th century by Gregory the Great. However, Gregory the Great also notes that the power of Satan is from God as all other powers, he just distorted his power with his God-given free will. Even at the level of worldly wisdom aphorisms there is a conventional belief that our shortcomings are the continuation of our merits, and therefore it is necessary to adhere to the golden mean. Accroding to A. Gracheva in the book «Dialogues of Janus: Belles lettres and classics in the Russian literature of the early twentieth century», at the beginning of the 19th century, the mythologism of the spontaneous and not experimental type (often encyclopaedic and «algebraic» like in the works of Joyce and Bely, is especially pronounced in the works of writers, who are close to mass literature with their democracy or «boudoir» and especially in the works of female writers. This is due both to existing archetypes of the collective unconscious (some of which are even atavistic and «migratory plots» which are characteristic of both folklore and popular culture. Despite the compelling erotic subject matter, belles lettres is not always frivolous and, on the contrary, it is edifying and full of moral questions, which are sometimes rhetorical: «What is a sin and what does the

    The 20th century surface air temperature (SAT) records of China from various sources are analyzed using data which include the recently released Twentieth Century Reanalysis Project dataset. Two key features of the Chinese records are confirmed: (1) significant 1920s and 1940s warming in the temperature records, and (2) evidence for a persistent multidecadal modulation of the Chinese surface temperature records in co-variations with both incoming solar radiation at the top of the atmosphere as well as the modulated solar radiation reaching ground surface. New evidence is presented for this Sun-climate link for the instrumental record from 1880 to 2002. Additionally, two non-local physical aspects of solar radiation-induced modulation of the Chinese SAT record are documented and discussed.Teleconnections that provide a persistent and systematic modulation of the temperature response of the Tibetan Plateau and/or the tropospheric air column above the Eurasian continent (e.g., 30°N-70°N; 0°-120°E) are described. These teleconnections may originate from the solar irradiance-Arctic-North Atlantic overturning circulation mechanism proposed by Soon (2009). Also considered is the modulation of large-scale land-sea thermal contrasts both in terms of meridional and zonal gradients between the subtropical western Pacific and mid-latitude North Pacific and the continental landmass of China. The Circum-global teleconnection (CGT) pattern of summer circulation of Ding and Wang (2005) provides a physical framework for study of the Sun-climate connection over East Asia. Our results highlight the importance of solar radiation reaching the ground and the concomitant importance of changes in atmospheric transparency or cloudiness or both in motivating a true physical explanation of any Sun-climate connection. We conclude that ground surface solar radiation is an important modulating factor for Chinese SAT changes on multidecadal to centennial timescales. Therefore, a

    The record and analysis of statistical information on disaster occurrence, impacts and losses have been made worldwide in recent years. The development of natural disasters databases is crucial for risk management purposes, because it allows improving systems of indicators on disaster risk and vulnerability at national and sub-national scales. During the last century, Portugal was affected by several destructive natural disasters, namely of hydrologic (floods) and geomorphologic (landslides) origin. However, only recently risk prevention and management was assumed to be a national priority by the Portuguese Government. The basic information on past floods and landslides that occurred in Portugal is disperse and incomplete, and this is a shortcoming for the implementation of effective disaster mitigation measures, particularly when it is expectable an increase of frequency, magnitude, dimension and complexity of the hydro-geomorphologic phenomena resulting from climate change. In this work we present a preliminary assessment of hydro-geomorphologic disasters occurred in Portugal during the 20th century, based on the systematic survey of daily national newspapers. We included into a database those floods and landslides that produced, alternatively, dead people, injured people, missing people, evacuated and homeless. A total of 937 hydro-geomorphologic events were registered. In addition to physical and material damages, these events produced economic losses amounting to millions Euros. Our attention will focus on the geographic distribution and the temporal dimension of disastrous floods and landslides occurred in Portugal, and the temporal trends of hydro-geomorphologic disasters will be presented. The preliminary results shown that disastrous floods and landslides have been more frequent on the most populated regions of Portugal: the metropolitan areas of Lisbon and Oporto. In addition, data shows that disastrous hydrologic and geomorphologic phenomena were more

    As the topmost predator in Antarctica,the seal is a unique indicator of Antarctic environment and climate changes.In this study,we collected a sediment core from the Fildes Peninsula of West Antarctica,and used cholesterol,cholestanol,epicoprostanol,coprostanol,and seal hair numbers as the proxy indicators of seal population size and phytol as of general vegetation,and we reconstructed the 20th century history of variation of the seal population and vegetation abundance on this island.The sealing industry in the early 20th century caused the dramatic decline of seal population,and the ban of seal hunting since the 1960s led to its recovery of seal population.The seal population during the past century was primarily controlled by human activities and krill density.The reconstructed relation between seal population and vegetation abundance may offer new insights into Antarctic environment and ecology.

    This is the final scientific report for grant DOE-FG02-08ER64588, "The Interhemispheric Pattern in 20th Century and Future Abrupt Change in Regional Tropical Rainfall."The project investigates the role of the interhemispheric pattern in surface temperature – i.e. the contrast between the northern and southern temperature changes – in driving rapid changes to tropical rainfall changes over the 20th century and future climates. Previous observational and modeling studies have shown that the tropical rainband – the Intertropical Convergence Zone (ITCZ) over marine regions, and the summer monsoonal rainfall over land – are sensitive to the interhemispheric thermal contrast; but that the link between the two has not been applied to interpreting long-term tropical rainfall changes over the 20th century and future.The specific goals of the project were to i) develop dynamical mechanisms to explain the link between the interhemispheric pattern to abrupt changes of West African and Asian monsoonal rainfall; ii) Undertake a formal detection and attribution study on the interhemispheric pattern in 20th century climate; and iii) assess the likelihood of changes to this pattern in the future. In line with these goals, our project has produced the following significant results: 1.We have developed a case that suggests that the well-known abrupt weakening of the West African monsoon in the late 1960s was part of a wider co-ordinated weakening of the West African and Asian monsoons, and driven from an abrupt cooling in the high latitude North Atlantic sea surface temperature at the same time. Our modeling work suggests that the high-latitude North Atlantic cooling is effective in driving monsoonal weakening, through driving a cooling of the Northern hemisphere that is amplified by positive radiative feedbacks. 2.We have shown that anthropogenic sulfate aerosols may have partially contributed to driving a progressively southward displacement of the Atlantic Intertropical

    Health progress, as measured by the decline in mortality rates and the increase in life expectancy, is usually conceived as related to economic growth, especially in the long run. In this investigation it is shown that economic growth is positively associated with health progress in Sweden throughout the 19th century. However, the relation becomes weaker as time passes and is completely reversed in the second half of the 20th century, when economic growth negatively affects health progress. The effect of the economy on health occurs mostly at lag 0 in the 19th century and is lagged up to 2 years in the 20th century. No evidence is found for economic effects on mortality at greater lags. These findings are shown to be robustly consistent across a variety of statistical procedures, including linear regression, spectral analysis, cross-correlation, and lag regression models. Models using inflation and unemployment as economic indicators reveal similar results. Evidence for reverse effects of health progress on economic growth is weak, and unobservable in the second half of the 20th century.

    Full Text Available The masters, or owners, of mining rights for the exploration of ores were prospectors and free or independent prospectors. Concession books and registers were kept about the proprietors of ore fields or mines. In them was entered, among other things, which ore was planned to be exploited. The possessor of a licence, permits for exploration and exploitation of ores, paid a certain fee every year. He could also sell his mining righis. in the shape of permits, partially or, more frequently, totally, as was recorded in the books. If he did not pay taxes, he could lose all his rights, which were then deleted, or crossed out of the mining books. Those who possessed mining permits had to solve the questions of compensation to the owners of the lands where they intended to do detailed explorations, and to exploit the ore, even to the extent of leasing or buying the land. The mining activity in Croatia between the mid-19th and mid-20th centuries is richly documented in the (Imperial and Royal mining captaincies in Zagreb, Zadar and Split. The basic mining law was the General Austrian Mining Law of 1854, with its amendments of 1911 (Legal Article VI about mineral oil substances and natural gases. In Croatia, mining enterpreneurs were individuals or companies (including the slate with the proviso that at the beginning there were more foreigners. However, Croatian traders, industrialists, magnates, officials, bankers, various companies, engineers, artists, retired persons, peasants, officers and others soon became involved in mining. Among the entrepreneurs there were various noblemen. It has been ascertained in this research that in individual periods between 1855 and 1945 there was a dominance of individuals (mainly 81%-85% while today (1990-1995 it is quite the opposite (86% are companies, because this is the end of the long term control of the socially owned companies.

    High water stress due to economic growth and climate change (ex. global warming) will be falling into 2 billion people to 4 billion people in the future. Agricultural water use accounting for about 70% of global water consumption might continue to increase due to production of foods and biofuels occurred by population growth in the future. In particular, water demand, food and biofuel production have an inextricable link. It is very important to evaluate these relationship for sustainable water use from past to the future. In this study, we focused on the objective to assess the impact of water withdrawal from various sources (stream flow, medium-sized reservoirs and nonrenewable nonlocal blue water) in the 20th century by considering irrigation area and climate change. Irrigation water withdrawal is the most important water use sector accounting for about 90% of total water withdrawal. First, we make the global spatial database of equipped irrigation area change and medium-sized reservoirs capacity. Then, water withdrawal from each sources for 50 years from 1950 to 2000 were simulated in global-scale at a resolution of 1.0 degree x 1.0 degree using an integrated global water resources model (hereafter, the H08 model). The H08 model can simulate both natural or anthropogenic water flow and anthropogenic water withdrawals. For comparison with our results, distribution of agricultural, industrial and domestic water withdrawals from 1950 to 2000 were estimated by distributing the country-based withdrawal data from AQUASTAT with irrigation area, urban population and total population, respectively. Groundwater withdrawal was then estimated by distributing the country-based withdrawal data based on statistical data from WRI, IGRAC and AQUASTAT with the total water withdrawal. As a result, agricultural water withdrawal change from nonrenewable nonlocal blue water during the past 50 years agreed well with the observed groundwater abstraction based on statistical data. In

    2014-07-01

    Full Text Available Oceanic heat transport variations, carried by the northward flowing Atlantic Water, strongly influence Arctic sea-ice distribution, ocean–atmosphere exchanges, and pan-Arctic temperatures. Paleoceanographic reconstructions from marine sediments near Fram Strait have documented a dramatic increase in Atlantic Water temperatures over the 20th century, unprecedented in the last millennium. Here we present results from Earth system model simulations over the last millennium that reproduce and explain reconstructed integrated quantities such as pan-Arctic temperature evolution during the pre-industrial millennium as well as the exceptional Atlantic Water warming in Fram Strait in the 20th century. The associated increase in ocean heat transfer to the Arctic can be traced back to changes in the ocean circulation in the sub-polar North Atlantic. An interplay between a weakening overturning circulation and a strengthening sub-polar gyre as a consequence of 20th century global warming is identified as driving mechanism for the pronounced warming along the Atlantic Water path toward the Arctic. Simulations covering the late Holocene provide a reference frame that allows us to conclude that the changes during the last century are unprecedented in the last 1150 years and that they cannot be explained by internal variability or natural forcing alone.

    Demeter Georgievitz-Weitzer (1873-1949), called "Surya", Sanskrit for "sun", was an important representative of medical occultism in the first half of the 20th century. He worked as a journal editor and published a 13-volume book series about occult medicine, mainly written by himself. His hypotheses were closely related to the "Lebensreform" movement around 1900. Regarding diagnostics, he relied on astrology, cheiromancy, and clairvoyance, while therapeutics were dominated by diet and spagyric remedies according to Cesare Mattei (1809-1896) and Carl-Friedrich Zimpel (1801-1879). In his later years, he developed his own healing system, initially comprising eight, later only two preparations. Surya remedies were commercially available until the end of the 20th century, PMID:22822609

    Full Text Available The article focuses on the question of the distribution of added value in the mining industry in Siberia in the late 19th – early 20th centuries. Relying on the analysis of financial reports from Siberian goldmines and coalmines, the author reveals the correlation between the means spent on workforce and the means spent on income and the companies’ non-production expenses. The calculated norm of added value – the most precise reflection of the measure of wage labour exploitation – turned out to be higher for Siberian mine workers in the late 19th – early 20th centuries than for workers in the European Russia and demonstrated the tendency to further growth. The author believes it to be a consequence of the modernization of production and the exploitation of the richest and most easily accessible Siberian deposits.

    The decommissioning of nuclear submarines, disposal of highly-enriched uranium and weapons-grade plutonium, and processing of high-level radioactive wastes represent the most challenging issues facing the cleanup of 20th century radiation legacy wastes and facilities. The US and Russia are the two primary countries dealing with these challenges, because most of the world's fissile inventory is being processed and stored at multiple industrial sites and nuclear weapons production facilities in these countries.

    The density and contours of networks of transnational and international economic integration are hypothesized by many theorists to be causally related to the patterns of cooperation and conflict. [1] The usual notion is that trade creates ties of symmetrical interdependence, which are likely to inhibit conflict. We seek to test this hypothesis in the 19th and early 20th century run-up to World War I. We examine the relationship between the structure of conflict and the contours of trade ties ...

    Adriatic and Black Sea are semi-enclosed basins characterized by densely populated coasts, industrial compounds and a rich cultural and historical heritage. It appears to be crucial, for the management and the protection of their coastlines, to understand how much they will be impacted by the global sea level (SL) rise, projected by the end of this century. The aim of this work is to develop a method that allows to estimate to which extent the SL of the two basins will depart from the mean global level. The future evolution of global sea level is not a meaningful indicator at this regional scale and past deviations, due to local factors of the Adriatic and Black Sea levels from the global one, have been observed. The Adriatic Sea is the basin of the Mediterranean Sea best covered by past SL observations. In fact, for the Adriatic Sea is possible to obtain, by statistical method based on PCA and Least square Method, a seamless and long time series (from 1900 to 2009) using records of 7 mareographic stations located along the Italian and Croatian coasts (from PSMSL database). Satellite data of SL are available for the whole Mediterranean from 1993 to 2012 and they show a very high correlation (rho > 0.9) with Adriatic time series based on mareographic records. The SL time series of the 20th century in the Black Sea is computed using data of 4 stations, which are available in the PSMSL (Permanent Service for Mean Sea Level) archive, located on the north-east coast. This time series shows a lower correlation (rho about 0.5) with satellite data than in the case of Adriatic Sea. Further it shows a higher interannual variability. All the time series are considered after the subtraction of the Inverse Barometer (IB) effect. A statistical approach, based on a multivariate linear regression model, is used to investigate the link between SL anomaly, computed as the difference between the regional SL and global SL, and three large scale climate variables (sea level pressure

    Full Text Available In this last part of our attempt to present briefly the history of Croatian chemistry in the 20th century, the development of chemistry in the Republic of Croatia, established as an independent state on June 25th, 1991 is outlined. The last 10 years of the 20th century are characterized first by defense of the country by arms until 1995, and then until the end of century, and after the constructive building of the foundations of Croatia. In these turbulent times, scientists could not be just bystanders. Thus, some went to defend the country by arms and others (perhaps older kept informing colleagues all around the globe about our defense of the homeland. This was the reason why scientific research in Croatia showed very limited results. This article briefly describes research in chemistry at the Faculty of Natural Sciences and Mathematics, the Rugjer Bošković Institute, Faculty of Chemical Engineering and Technology, Faculty of Pharmacy and Biochemistry, Faculty of Medicine, Faculty of Veterinary Medicine, Faculty of Agronomy and Faculty of Forestry.

  9. Consistent QBO-dependent effect of geomagnetic activity on the Northern Annular Mode during the 20th century

    Science.gov (United States)

    2016-04-01

    Several earlier studies have shown that geomagnetic activity (GA), as a proxy for energetic particle precipitation into the atmosphere, affects the winter-time Northern Annular Mode (NAM), which is the dominant circulation pattern in the northern hemisphere during winter. It has also been found that the quasi-biennial oscillation (QBO) modulates the relationship between GA and NAM. However, some of the earlier studies on this QBO modulation have been mutually conflicting, with some studies suggesting a stronger positive relation in the easterly phase of the QBO, while other studies suggest a stronger positive relation in the westerly phase of the QBO. Here we study the QBO-GA-NAM relationship using a QBO reconstruction covering the whole 20th century. We find that the QBO modulation of the GA-NAM relation is temporally variable, which explains the earlier, seemingly differing results. Positive GA-NAM relation is found to be valid in the easterly QBO phase at 30 hPa during the whole 20th century. We also find that the QBO at 30 hPa represents the Holton-Tan relation for the surface circulation better than QBO at 50 hPa, and that the Holton-Tan relation is only observed during early/mid winter, while an anti-Holton-Tan relation is found in the late winter for strong geomagnetic activity. These results emphasize the variable but systematic response of NAM to energetic particle precipitation during the entire 20th century, and underline the importance of considering the preconditioning of the atmosphere when studying the solar-related effects upon climate.

    Starting in the 1960s, the Indian chemist Krishna Bahadur, from the University of Allahabad, published on organic and inorganic particles that he had synthesized and baptized `Jeewanu’, or `particle of life’. Bahadur conceived of the Jeewanu as a simple form of the living. These studies are presented in a historical perspective and positioned within mid-20th century research on the origin of life, notably the so-called `coacervate theory’ of the Soviet biochemist Aleksandr I Oparin.

    We provide empirical evidence on the existence of the Pigou-Dalton principle. The latter indicates that aggregate welfare is - ceteris paribus - maximized when incomes of all individuals are equalized (and therefore marginal utility from income is as well). Using anthropometric panel data on 101 countries during the 19th and 20th centuries, we determine that there is a systematic negative and concave relationship between height inequality and average height. The robustness of this relationship is tested by means of several robustness checks, including two instrument variable regressions. These findings help to elucidate the impact of economic inequality on welfare. PMID:23352274

  16. The Lowland Rivers of The Netherlands - Geodiversity and Cultural Heritage on 19th and early 20th century Landscape Paintings

    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

    Marques, Rita de Cássia

    2011-01-01

    This article is the fruit of research into the cultural heritage of healthcare in Minas Gerais (Brazil) and explores the construction of hospitals supported by Catholic charities from the 18th to 20th century. Catholicism has always been strong in Minas Gerais, partly because the Portuguese Crown prohibited the free travel of priests, who were suspected of illegally trading in gold from the mines. A brotherhood was responsible for creating the first Santa Casa, in Vila Rica. Another very important religious group in Brazil, the Vincentians, was also devoted to charitable works and propagated the ideas on charity of Frederico Ozanan, based on the work of St. Vincent de Paul. This group comprised both a lay movement, supported by conferences organized by the St. Vincent de Paul Society, and a religious order, the Vincentian priests and nuns. Catholic physicians make up the third group studied here, organized in a professional association promoted by the Catholic Church. The brotherhoods, Vincentians, and associations, with their Santa Casas, represent a movement that is recognized worldwide. The enormous Catholic participation in these charitable works brought in the physicians, who would often make no charge and exerted efforts to create hospitals that served the population. Although the capital of Minas Gerais was the creation of republicans and positivists in the 20th century, with their ideas of modernity, it remained dependent on Christian charity for the treatment of the poor.

    Full Text Available This article aims to analysis the Brazilian city between late 19th and the early 20th century, when there are structural changes in the economic, social and political framework that will lead to new forms of production and consumption of the city and housing. It overlaps the archaic matrix of colonial trait a new guise that disguised as modern has only exacerbated their dramatic njustices, leading to production of a segregated urban space, both socially and space terms. The access to land and the State participation are central to the explanation of theses inequalities. The methodological procedures include bibliographic survey, selection and reading, data compilation, data and information systematization, data analysis. We conclude that, between late 19th and early 20th century, the Brazilian cities are the product of urbanization whose logic state intervention produced clear inequalities between sectors of the city, because it favored those spaces fitted with infrastructure at the expense of the shortage of rest of the city.

  1. Response of the everglades ridge and slough landscape to climate variability and 20th-century water management

    Science.gov (United States)

    Bernhardt, C.E.; Willard, D.A.

    2009-01-01

    The ridge and slough landscape of the Florida Everglades consists of a mosaic of linear sawgrass ridges separated by deeper-water sloughs with tree islands interspersed throughout the landscape. We used pollen assemblages from transects of sediment cores spanning sawgrass ridges, sloughs, and ridge-slough transition zones to determine the timing of ridge and slough formation and to evaluate the response of components of the ridge and slough landscape to climate variability and 20th-century water management. These pollen data indicate that sawgrass ridges and sloughs have been vegetationally distinct from one another since initiation of the Everglades wetland in mid-Holocene time. Although the position and community composition of sloughs have remained relatively stable throughout their history, modern sawgrass ridges formed on sites that originally were occupied by marshes. Ridge formation and maturation were initiated during intervals of drier climate (the Medieval Warm Period and the Little Ice Age) when the mean position of the Intertropical Convergence Zone shifted southward. During these drier intervals, marsh taxa were more common in sloughs, but they quickly receded when precipitation increased. Comparison with regional climate records suggests that slough vegetation is strongly influenced by North Atlantic Oscillation variability, even under 20th-century water management practices. ?? 2009 by the Ecological Society of America.

    2016-06-01

    Full Text Available The Hlučín Region is a small border area in the Moravia-Silesia Region. Its history is specific. Over 25 years in the 20th century, its border shifted three times and its inhabitants’ nationality also changed three times. The region was annexed by the German Reich in 1938 and its inhabitants gained the rights of citizens of the Reich, with the obligation to enlist in the Wehrmacht, the armed forces of Germany. These historical turning points and their consequences after the Second World War are part of the cultural and communicative memory of most of the local people. The purpose of the article is to show the communicative memory of Hlučín Region inhabitants and the common knowledge of 20th century historical events to be one of the important integral parts of regional identity, which is a source of regional consciousness. Hlučín Region inhabitants identify themselves strongly with their region and society. This identification results from specific culture finding its expression in shared values, faith and traditions, and from the awareness of their own specificity. As a consequence of the predominant regional endogamy, this culture is handed down from one generation to another. Strong regional consciousness based on this identification, has a positive influence on the rich communal life and possibilities of stabilization and further development of the region.

    2014-01-01

    A long-term decrease in downward surface solar radiation from the 1950s to the 1980s ("global dimming") followed by a multi-decadal increase up to the present ("brightening") have been detected in many regions worldwide. In addition, some researchers have suggested the existence of an "early brightening" period in the first half of 20th century. However, this latter phenomenon is an open issue due to the opposite results found in literature and the scarcity of solar radiation data during this period. This paper contributes to this relevant discussion analyzing, for the first time in Southern Europe, the atmospheric column transparency derived from pyrheliometer measurements in Madrid (Spain) for the period 1911-1928. This time series is one of the three longest dataset during the first quarter of the 20th century in Europe. The results showed the great effects of the Katmai eruption (June 1912, Alaska) on transparency values during 1912-1913 with maximum relative anomalies around 8%. Outside the period affect...

    Results have been presented for studies of the microstructure and chemical composition of a number of articles made of iron and cast iron at the Kamensk plant, which cover the period from the start of the production of iron on the territory of the city of Kamensk-Ural'skii at the turn of the 17th-18th centuries to the beginning of the 20th century. Differences in the composition of the Kamensk cast iron and modern grades of foundry cast iron have been established. Possible sources of technological difficulties and production waste at the Kamensk plant have been revealed. The potential of metallographic studies for the attribution of historical articles made of ferrous metals are shown.

    This study investigates the Arctic Ocean warming episodes in the 20th century using both a high-resolution coupled global climate model and historical observations. The model, with no flux adjustment, reproduces well the Atlantic Water core temperature (AWCT) in the Arctic Ocean and shows that four largest decadalscale warming episodes occurred in the 1930's, 70s, 80s, and 90s, in agreement with the hydrographic observational data. The difference is that there was no pre-warming prior to the 1930s episode, while there were two pre-warming episodes in the 1970s and 80s prior to the 1990s, leading the 1990s into the largest and prolonged warming in the 20th century. Over the last century, the simulated heat transport via Fram Strait and the Barents Sea was estimated to be, on average, 31.32 TW and 14.82TW, respectively, while the Bering Strait also provides 15.94 TW heat into the western Arctic Ocean. Heat transport into the Arctic Ocean by the Atlantic Water via Fram Strait and the Barents Sea correlates significantly with AWCT ( C =0.75 ) at Olag. The modeled North Atlantic Oscillation ( NAO ) index has a significant correlation with the heat transport ( C = 0.37 ). The observed AWCT has a significant correlation with both the modeled AWCT (C =0.49) and the heat transport (C =0.41 ).However, the modeled NAO index does not significantly correlate with either the observed AWCT (C =0.03 ) or modeled AWCT (C = 0. 16) at a zero-lag, indicating that the Arctic climate system is far more complex than expected.

    Portugal’s forests in the 12th century were dominated by the Fagaceae represented by Quercus and Castanea, and several pine species. From the 12th century onwards, forests underwent changes in their man-agement starting with protection and ultimately leading to intense ex-ploitation. The massive naval construction during the maritime expansion (mainly in the 15th-16th centuries) involved felling of approximately 5 million trees mainly Quercus suber, Pinus pinea and other Quercus species. Cumulative fuel-wood consumption of 959 Mm3 during 1300-1854 was attributed to demographic expansion while the deforesta-tion rate during 1636-1854 accounted for a minimum of 72.6% and a maximum of 96% of total forest cover. The volume of timber used in railway sleepers from 1856 onwards might have reached 0.5 Mm3. The last quarter of the 20th century increased the forest cover of Portugal through the World Bank program of Eucalyptus globulus reforestation.

  17. Rolling-element bearings in China: From ancient times to the 20th century

    2016-03-01

    The development of rolling-element bearings in China has spanned a long period. Based on several typical and important cases, the present article reconstructs the history of rolling-element bearings in China by dividing it into four stages according to the various characteristics of the bearings. The first stage represents the origin of rolling bearings in China, which remains controversial because of several suspected races and cages that were likely the components of bearings more than a millennium ago. At the second stage, a type of simple roller bearing was used for astronomical instruments not later than the 13th century based on clear philological and physical evidence. A similar bearing was also applied to an abridged armillary in the 17th century. Another type of spherical thrust bearings with rolling elements, which is a key component of a traditional Chinese windmill, could support a rotating shaft that moves rotationally and at an angle. At the third stage, the Chinese began studying and using the so-called Europeanstyle bearing since the 17th century. Moreover, over the last 100 years, the modern rolling bearing industry was gradually established in China, particularly because of the technology transfer from the Soviet Union in the 1950s. At the fourth stage, the Chinese government initiated the relatively rapid development of bearing technology. The government launched the "bearing movement" from the 1950s to the 1960s to establish the modern bearing industry and to promote rolling bearings as replacement for traditional sliding bearings. Furthermore, a number of large professional factories and institutions in China have continually introduced advanced technology and equipment. At present, these companies and institutions play a significant role in the international bearing industry.

    Full Text Available In this article I examine the position of women in Islam, from the beginning of the 19th century till the end of the Second World War, through the eyes of female travel writers. The first women travellers who set out for the Middle East were the first outsiders to be accepted into women’s societies in the Islamic world, and thus they entered the life behind the veil. Comparing writers’ encounters with Muslim women and the Muslim world in general, I describe Muslim women throughout various stages of life.

    2009-04-01

    Climate simulations with an atmospheric general circulation model driven with natural and anthropogenic forcings have been carried out from 1870 to 2000. The atmospheric GCM ECHAM5 is interactively coupled to the atmospheric aerosol module HAM, while the SSTs are based on data from the Hadley Center dataset. Aerosol emissions are taken from the National Institute for Environmental Studies (NIES), and include SO2 and black carbon from fossil fuel combustion as well as black carbon from biomass burning. Other forcings included in the simulations are changes in greenhouse gases, DMS, solar output and volcanic activities. Global simulations will give a general overview of the climate evolution since the mid-nineteenth century, and will allow the definition of limits to further regional simulations. Sensitivity experiments are carried out, in order to understand better the impact of the the different forcings on the climate since the mid-nineteenth century. Results are discussed with particular emphasis on the hydrological and radiation conditions under different forcings.

  1. Increase of upper troposphere/lower stratosphere wave baroclinicity during the second half of the 20th century

    Full Text Available A strengthening of the equatorward temperature gradient in the upper troposphere/lower stratosphere (UTLS, at subtropics and midlatitudes, is consistently reproduced in several modelling studies of the atmospheric response to the increase of greenhouse gas radiative forcing. Some of those studies suggest an increase of the baroclinicity in the UTLS region because of the enhanced meridional temperature gradient.

    This study presents observational evidence of an increase of UTLS wave baroclinicity, during the second half of the 20th century. The evidence is given by significant positive trends in the energy of baroclinic normal modes of the NCEP/NCAR reanalysis, and significant positive trends in the eddy available potential energy of the ERA-40 reanalysis as well as in the eddy available potential energy of the JRA-25 reanalysis. Significant positive trends in the frequency of double tropopause events in radiosonde data are also interpreted as a manifestation of an increase of the UTLS wave baroclinicity.

    Throughout the 20th century, US public health and immigration policies intersected with and informed one another in the country's response to Mexican immigration. Three historical episodes illustrate how perceived racial differences influenced disease diagnosis: a 1916 typhus outbreak, the midcentury Bracero Program, and medical deportations that are taking place today. Disease, or just the threat of it, marked Mexicans as foreign, just as much as phenotype, native language, accent, or clothing. A focus on race rendered other factors and structures, such as poor working conditions or structural inequalities in health care, invisible. This attitude had long-term effects on immigration policy, as well as on how Mexicans were received in the United States.

    Alpine glacier retreat resulting from global warming since the close of the Little Ice Age in the 19th and 20th centuries has increased the risk and incidence of some geologic and hydrologic hazards in mountainous alpine regions of North America. Abundant loose debris in recently deglaciated areas at the toe of alpine glaciers provides a ready source of sediment during rainstorms or outburst floods. This sediment can cause debris flows and sedimentation problems in downstream areas. Moraines built during the Little Ice Age can trap and store large volumes of water. These natural dams have no controlled outlets and can fail without warning. Many glacier-dammed lakes have grown in size, while ice dams have shrunk, resulting in greater risks of ice-dam failure. The retreat and thinning of glacier ice has left oversteepened, unstable valley walls and has led to increased incidence of rock and debris avalanches. ?? 1993 Kluwer Academic Publishers.

  4. Evaluation of Continental Precipitation in 20th-Century Climate Simulations: The Utility of Multi-Model Statistics

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, T J; Gleckler, P J

    2005-11-01

    At the request of the Intergovernmental Panel on Climate Change (IPCC), simulations of 20th-century climate have been performed recently with some 20 global coupled ocean-atmosphere models. In view of its central importance for biological and socio-economic systems, model-simulated continental precipitation is evaluated relative to three observational estimates at both global and regional scales. Many models are found to display systematic biases, deviating markedly from the observed spatial variability and amplitude/phase of the seasonal cycle. However, the point-wise ensemble mean of all the models usually shows better statistical agreement with the observations than does any single model. Deficiencies of current models that may be responsible for the simulated precipitation biases as well as possible reasons for the improved estimate afforded by the multi-model ensemble mean are discussed. Implications of these results for water-resource managers also are briefly addressed.

  5. Methodological disputes about interpretation of neum notation in the 20th century

    2015-01-01

    Full Text Available Until the end of the twentieth century in Byzantine musicological science there were two diametrically opposite approaches to the interpretation of the Byzantine neum notation systems and post-Byzantine music heritage after the Fall of Constantinople. Western European scholars, ignoring the post-Byzantine Chant tradition and the last semeography reform from the early nineteenth century, looked at the problems of the musical past only from the perspective of the Middle Ages. Greek researchers have shared the belief that the condition of an adequate understanding of the mid-Byzantine notation, or the so-called old method, is the knowledge of analytical neum system and theory, the basics of which were set up by musicians from the end of the seventeenth and during the eighteenth century, and were finally shaped by Chrisantos, Gregory and Chourmouzios and officially accepted in the Greek church in 1814. The path to overcoming the issues relating to the development of neum notation, and finding an adequate manner of decoding it, led through the understanding of the phenomenon of "interpretation" and other tendencies that marked the post-Byzantine music practice. Two scientists -the Danish Jørgen Raasted, a follower of the Western European musicological methods established by founders of Monumenta Musicae Byzantinae, and Greek theologist and musicologist Gregory Stathes - are specifically responsible for the reconciliation of the different methodological approaches. After numerous and often heated debates, the Danish scientist eventually largely accepted the views of his Greek counterpart. Moreover, he himself insisted, at the musicological conferences organized during the 1980s, on reviewing the controversial issues: the existence of chromatic intervals in the psalmody of the Middle-Ages, the problem of syllabic and melismatic interpretations of stenographic neum records, and so on. Concerning the above mentioned issues, the contemporary trends in

    The second half of the nineteenth century in Spain was a period characterized by a strong presence of social science, which even came to permeate the masses. Evolutionary theories and some figures such as Charles Darwin himself were present in areas far from the scientific activity proper. The use of concepts and laws of biological origin for the diagnosis and political practice against certain problematic social realities, such as crime or poverty, gave rise to theories and intellectual schools that asserted the value of evolutionary principles for the analysis of complex realities of socio-cultural inequality. The attraction for difference and the scientific method, with the possibility of observation of poverty and social inequality that industrial development and modernity put forward to the writers, added to the naturalist and biological interest a literary curiosity for the degeneration, both physical and cultural, of that unfortunate part of humanity.

    Based on analyses of the share of documents of structural geology and tectonics in the GeoRef system over 100 years in the last century, and the historical change of international (31 years) and domestic (16 years) document counts of various topics in structural geology and tectonics, the position of structural geology and tectonics in the geosciences is evaluated and the major advaces in fields of plate tectonics, continental dynamics and global dynamics are reviewed. Our attention mainly focuses on the advances in studies of structural analysis, deformation mechanisms and rheology of rocks,contractional tectonics and late- and post-orogenic extensional collapse in orogens, large-scale strikeslip faults and indentation-extrusion tectonics, active tectonics and natural hazards. The relationships of structural geology and tectonics with petrology and geochronology are also discussed in terms of intersection of scientific disciplines. Finally, some suggestions are proposed for the further development of structural geology and tectonics in China.

    Full Text Available Common practices, whether recognized or not as a source of law, represented an area of great importance in economic practice and judicial bodies, especially in maritime and river transport, but also rail and air transport. The Civil Code of 1864 made some references to local custom, while the new Civil Code provisions establish that practices are sources of law. In this way was settled a particularly sensitive area, namely, the existence and applicability of common practices in special matters such as those on business, commercial transactions, financial and otherwise, being directly related to maritime and river transport. This study attempts to identify specific features of the common practices application in Galaţi port in the early twentieth century.

    Rejuvenation by monkey testicle transplanting was terribly fashionable in Paris, between years 1925-1930. The manual miracles done by a group of very well-known surgeons, in Paris, (especially Serge Voronoff and Dartigues) rooted in the head of a too credulous public the idea according to it was possible to be made scientifically younger by genital graftings. The "Etude sur la vieillesse et la rajeunissement par la greffe" (1926), written by Voronoff, provided the clinical, histological and iconographical proofs of a such rejuvenation. The paper analyses that was put forward as "proofs", situated in the scientific and cultural context of the time. A possible link between youth, sexual vigour and animality sends back to a mythic history of gerontology and endocrinology, two medical fields which however became scientific specialties in the beginning of the twentieth century.

    Claudio Varagnoli

    2016-06-01

    Full Text Available Pescara was born from the merger of two small existing towns, in 1926. The new town thus feels like a place with no past, no history; something that is far from the truth. This notion has endorsed the ongoing demolition and replacement, even in recent times. An initial survey of the architectural heritage carried out by L. Bartolini Salimbeni, in 1994, highlighted considerable architectural heritage, that should have been defended by a variant of the urban master plan approved in 2007. However, recent demolitions of buildings of a certain importance (the Porta Nuova Station, the former Centrale del Latte, a textile mill from the early twentieth century proceed amid protests from citizens and associations. The Town Hall tried to remedy the situation, entrusting revision of the current urban master plan to a group of experts, who extended the work of Bartolini Salimbeni. However, the Administrative Court rejected these and other attempts of protection, disputing the application of restrictive rules on the part of the Town Hall: only the Superintendence, the local office of the Ministry of Cultural Heritage, in fact, may apply such restrictions. The essay highlights the need to improve alternative means of protection instead of traditional ways. However, it also points out that, in Italy, the economic and financial aspects of “heritage” still prevail. New dangers threaten other important buildings, such as the Adriatic Stadium, designed by Luigi Piccinato (1952-56. The issue not only concerns the preservation of monuments, but also the quality of life of the inhabitants. The risk is that our towns will be reduced to mere merchandise.

  12. Are infant mortality rate declines exponential? The general pattern of 20th century infant mortality rate decline

    2009-08-01

    Full Text Available Abstract Background Time trends in infant mortality for the 20th century show a curvilinear pattern that most demographers have assumed to be approximately exponential. Virtually all cross-country comparisons and time series analyses of infant mortality have studied the logarithm of infant mortality to account for the curvilinear time trend. However, there is no evidence that the log transform is the best fit for infant mortality time trends. Methods We use maximum likelihood methods to determine the best transformation to fit time trends in infant mortality reduction in the 20th century and to assess the importance of the proper transformation in identifying the relationship between infant mortality and gross domestic product (GDP per capita. We apply the Box Cox transform to infant mortality rate (IMR time series from 18 countries to identify the best fitting value of lambda for each country and for the pooled sample. For each country, we test the value of λ against the null that λ = 0 (logarithmic model and against the null that λ = 1 (linear model. We then demonstrate the importance of selecting the proper transformation by comparing regressions of ln(IMR on same year GDP per capita against Box Cox transformed models. Results Based on chi-squared test statistics, infant mortality decline is best described as an exponential decline only for the United States. For the remaining 17 countries we study, IMR decline is neither best modelled as logarithmic nor as a linear process. Imposing a logarithmic transform on IMR can lead to bias in fitting the relationship between IMR and GDP per capita. Conclusion The assumption that IMR declines are exponential is enshrined in the Preston curve and in nearly all cross-country as well as time series analyses of IMR data since Preston's 1975 paper, but this assumption is seldom correct. Statistical analyses of IMR trends should assess the robustness of findings to transformations other than the log

    Full Text Available This essay relates improvements in social indicators in Bolivia during the Twentieth Century to ideological changes during the same period. During the Twentieth Century, most social indicators improved dramatically in Bolivia. Separately, scholars have vigorously debated ideologies, such as neoliberalism and its macroeconomic competitors, and the potential social impact of these ideologies. Despite the separate emphases on ideas and social outcomes, no systematic attempt has been made by scholars of Bolivia to link long–term ideological change to long–term social improvement in the country. This essay argues that it is probable that such a relationship exists, but it is important to consider mass ideology, which affects the whole of Bolivian society, in addition to elite ideology, which affects a much more limited portion of society.Este ensayo relaciona las mejoras en indicadores sociales en Bolivia durante el siglo XX con cambios ideológicos registrados durante el mismo periodo. Durante el siglo XX la mayoría de los indicadores sociales mejoraron dramáticamente en Bolivia. Los especialistas han debatido vigorosamente  la relación de estas mejoras con ideologías tales como el neoliberalismo y sus competidores macroeconómicos, discutiendo su potencial impacto social. Sin embargo, pese al énfasis otorgado a la relación de las ideas con los resultados sociales, no ha habido ninguna tentativa sistemática por parte de los especialistas de  relacionar el cambio ideológico de largo plazo con las mejoras sociales de largo plazo en el país. Este ensayo sostiene que es probable que tal relación exista, pero para visibilizarla es importante considerar la ideología de masas, que afecta al conjunto de la sociedad boliviana, además de la ideología de la élite, que afecta a una porción mucho más limitada de la sociedad.

    2011-12-01

    Full Text Available Originally published in Centropa: Journal of Central European Art and Architecture 5, n. 1 (January 2005: 16-25. Kimberly A. Smith discusses the ways in which the understanding of style was articulated by intellectuals working in the late nineteenth century, primarily in Germany and Austria, and the epistemological repercussions of this shift in thinking for both the theory and practice of central European art in the years before World War I. Smith focuses in particular on the writings of Alois Riegl, in which this approach to thinking about style came to its most influential fruition, and proposes that Riegl’s conception of form had implications for artistic practice. Riegl’s methodological understanding of artistic form drew connections between morphological types and perceptions of reality, thereby altering the ways in which artists could conceive of aesthetic authenticity. Style itself could be seen as the harbinger of truth, opening up the possibility that any style might offer a genuine revelation of the real. Yet as Smith shows, the Rieglian theory of meaningful form may have encouraged an artistic pluralism that subverted the very Kunstwollen theory of historically unified style from which it sprung.

    In the early 1930s Greenlandic explorers and scientists began using airplanes as an effective mean of surveying and mapping the hitherto unknown and inaccessible lands. By replacing the dogsled and the drawing board with the seaplane and camera, huge areas could now be covered. Here in the 21st Century the photographs now serve as a snapshot of the state of the glaciers, and possess unique scientific value as they stand as the first testimony of hundreds of Greenlandic glaciers. In the summer of 2013, we flew in the paths of the early flights and captured the changes that occurred during the last 80 years. To revisit all the historic glaciers would be a near impossible, not to mention extremely expensive task, so we targeted the most important glaciers in terms of present mass loss as well as the most aesthetically appealing historical images. The result is a then-and-now comparison that vividly captures both the raw beauty of the land and the ongoing often dramatic glacial changes. As the historic flights covered nearly half the Greenlandic coast line, we capture both areas of massive retreat and areas of still stand and even advance. The Heinkel Seaplane is being prepared for a photo flight in southeast Greenland in 1933. Flying an open plane in 14.000 ft and -40 °C called for a special breed of pilots.

Research on different types of historical documents reflecting the characteristics of work organization in Novosibirsk archive Bureau's Department of archives and district executive committees archives, conditions of archival funds formation, classification and use, archivists staff appointments, their accounting and qualifications, allowed to accumulate the historiography and source studies experience on the organization of archives in Novonikolaevsk through the example of the Archival Bureau in the first five years of its existence. Archival materials stored in MPI «Novosibirsk City Archives» and GKU NSO «State Archives of the Novosibirsk region» were used as the documentary basis of the article.

  19. Indian Ocean zonal mode activity in 20th century observations and simulations

    The Indian Ocean zonal mode (IOZM) is a coupled ocean-atmosphere system with anomalous cooling in the east, warming in the west and easterly wind anomalies, resulting in a complete reversal of the climatological zonal sea surface temperature (SST) gradient. The IOZM has a strong influence on East African climate by causing anomalously strong October - December (OND) precipitation. Using observational data and historical CMIP5 (Coupled Model Intercomparison Project phase 5) model output, the September - November (SON) dipole mode index (DMI), OND East African precipitation and SON zonal wind index (ZWI) are calculated. We pay particular attention to detrending SSTs for calculating the DMI, which seems to have been neglected in some published research. The ZWI is defined as the area-averaged zonal wind component at 850 hPa over the central Indian Ocean. Regression analysis is used to evaluate the models' capability to represent the IOZM and its impact on east African climate between 1948 and 2005. Simple correlations are calculated between SST, zonal wind and precipitation to show their interdependence. High correlation in models implies a good representation of the influence of IOZM on East African climate variability and our goal is to detect the models with the highest correlation coefficients. In future research, these model data might be used to investigate the impact of IOZM on the East African climate variability in the late 20's century with regard to anthropogenic causes and internal variability.

    Windmills are one of the oldest prime movers and have been used for more than 700 years in Europe. The transition from low speed windmills for grain grinding and water pumping to high speed wind turbines for electric power generation had occurred at the end of 19{sup th} century. This paper, at first, reviews the windmill technologies and the researchers before 20th century. Then describes the back ground of how the wind power generator has existed and how the four pioneers developed their wind power generator. The historical developments of windmills to wind turbines in this century are studied focusing mainly on Danish activities. Then, the effort of the development of large wind turbine such as Smith-Putnum's first MW machine in U.S.A. and other mammoth machine concept are introduced. The new concept machines such as Savonius and Darrieus wind turbines in 1920s to 1930s are also explained. Finally, the novel technologies of wind turbine covering larger machines, variable speed generators, special wing sections for wind turbines, theoretical analysis method of wind turbine performance, offshore wind turbines, and wind turbine control technologies are stated.

  1. Placenta accreta: pathogenesis of a 20th century iatrogenic uterine disease.

    Placenta accreta refers to different grades of abnormal placental attachment to the uterine wall, which are characterised by invasion of trophoblast into the myometrium. Placenta accreta has only been described and studied by pathologists for less than a century. The fact that the first detailed description of a placenta accreta happened within a couple of decades of major changes in the caesarean surgical techniques is highly suggestive of a direct relationship between prior uterine surgery and abnormal placenta adherence. Several concepts have been proposed to explain the abnormal placentation in placenta accreta including a primary defect of the trophoblast function, a secondary basalis defect due to a failure of normal decidualization and more recently an abnormal vascularisation and tissue oxygenation of the scar area. The vast majority of placenta accreta are found in women presenting with a previous history of caesarean section and a placenta praevia. Recent epidemiological studies have also found that the strongest risk factor for placenta praevia is a prior caesarean section suggesting that a failure of decidualization in the area of a previous uterine scar can have an impact on both implantation and placentation. Ultrasound studies of uterine caesarean section scar have shown that large and deep myometrial defects are often associated with absence of re-epithelialisation of the scar area. These findings support the concept of a primary deciduo-myometrium defect in placenta accreta, exposing the myometrium and its vasculature below the junctional zone to the migrating trophoblast. The loss of this normal plane of cleavage and the excessive vascular remodelling of the radial and arcuate arteries can explain the in-vivo findings and the clinical consequence of placenta accreta. Overall these data support the concept that abnormal decidualization and trophoblastic changes of the placental bed in placenta accreta are secondary to the uterine scar and thus

    Belarus became a Soviet Socialist Republic in the USSR in 1921. Belarus is now an independent country between Poland and Lithuania and Russia. The pharmacy sector of Belarus improved in fits and starts from 1921 to the present but serious quantitative and qualitative problems were evident until the 21st century. A number of factors caused this situation. The Soviet Republic of Belarus started with handicaps. The area, comprised of several provinces of western Russia, had no pharmaceutical factories during the imperial period and, while pharmacies were of high quality in the cities all over the Russian Empire--including Minsk, which became the capital of Belarus--pharmacies were sparse and primitive in rural areas and Belarus was basically rural. Belarus was devastated by wars--World War I, the Russian-Polish war of 1920-21, and of course, by World War II. The Bolshevik policy of nationalizing private pharmacies adversely affected dispensing between 1918 and 1921. Dispensing improved during the New Economic Policy of 1921 to 1927 with re-introduction of private enterprise and the establishment of BelMedTorg and the Mogilev Experimental Station of Medicinal Plants. The number of pharmacies and medical facilities increased during the 1930s and again after World War II. However, utopian plans to provide free or low-cost medicines to all citizens never came to fruition. Inadequate amounts of state-of the-art and even basic medicines persisted through the 1990s. The number of pharmacists also was inadequate and their education and training was on a low level. Because of shortages, citizens of Belarus often self-medicated with medicinal plants. The transition to a market economy in the 1990s made medicines expensive for citizens but opened the door to greater interaction with Western pharmaceutical practices and physical improvements in pharmacies and pharmaceutical production.

    Snow accumulation records derived from ice cores are one of the only direct archives of precipitation changes that extend prior to the instrumental period. In Alaska, the development of centennial scale precipitation records is needed to contextualize the current rapid changes in precipitation and glacial mass balance occurring along the North Pacific margin. Here, we investigate precipitation changes over the last three centuries using an ice core collected to bedrock from Mt. Hunter (63° N, 151° W, 4,000 meters above sea level) in Denali National Park, Alaska. To develop the snow accumulation record, we calculated water equivalent annual layer thicknesses in the ice core by identification of annual peaks in major ions (MSA, Cl-, NO3-, SO42-, Na+, NH4+, K+, Mg2+, and Ca2+) and water isotopes. We then corrected the annual layer thickness for thinning using three different flow models (Nye, Hooke and Dansgaard-Johnsen) that have been widely used to simulate layer thickness with depth near an ice divide. Each of these models is optimized such that the discrepancy between the annual layer counted age scale and the modeled age scale is minimized. Our results show that water equivalent annual accumulation has increased from 1.43 meters in 1900 to 2.03 meters by 2012, an increase of 42%. The Mt. Hunter accumulation record is regionally representative of precipitation in southwest and central Alaska based on strong correlations with reanalysis precipitation data. Comparisons with ERA-Interim reanalysis data show that years of high accumulation on Denali are associated with stronger southerly winds, warmer sea surface and air temperatures, and pressure anomalies resembling a positive phase of the East Pacific-North Pacific Pattern. Together, this analysis shows that precipitation on Mt. Hunter has a strong positive correlation (R2=0.73) with annual average meridional wind strength in southwestern Alaska, which is related to atmospheric pressure gradients between the

    Full Text Available Maps provide a base for all intelligence operations and strategic and tactical decisions, supporting the planning and execution of all battlefield functions. The development of military mapping support in South Africa, related closely to the development of aerial photography, may be divided into five, sometimes overlapping, phases. The first of these phases spans the years from 1840 to 1930 and is characterised by the gradual recognition that aerial photographs could be used for mapping. Two major conflicts – the Anglo Boer War and the First World War – marked this development. The Second World War is the key event of the second phase (1930–1950, which witnessed a rapid expansion of aerial photo coverage. The third phase (1945–1960 saw the overemphasising of interpretation techniques rather than the analytical use of results, which was rectified during the fourth phase (1955–1962 when the focus shifted to the applied uses of air-photo interpretation. During the third and fourth phases the topographic mapping support ability of the South African military was expanded. The fifth phase (since 1960 commenced with the expansion of data gathering and analysis into portions of the electromagnetic spectrum beyond the small visible sector. During this period the protracted nature of the conflict on the northern border of Namibia (formerly South West Africa and the war in Angola focused attention on the South African military mapping system. The National Service system allowed for the expansion of mapping units and the thorough mapping of large areas adjoining our borders. Through all five phases, mapping in the South African military has advanced from hand-produced maps to the utilisation of complex equipment that satisfies the sophisticated mapping needs of a modern defence force.This paper presents a brief history of both mapping support and the mapping units that have served within the South African theatre during the twentieth century.

    Full Text Available The historical development of Lithuanian parks cannot be separated from the historical evolution of our cities and towns and formation of their urbanistic structure. The beginnings of creating garden art in Lithuania, the same as in West Europe, are mentioned in medieval castles and monasteries. A strong influence on the developement of the history of Renaissance gardens was exerted by new models of garden theory, which were formed and formulated by famous European architects, artists, scientists, philosophers. The traditions of antique art were revived, new scientific inventions had an influence on garden art. During the 17th–18th centuries a lot of residences and manors were built, and they played an important role in the urbanisation of the country. In the 17th–18th centuries the tendencies in the Italian art of garden parks in West Europe were taken over by French baroque. In the junction of the 18th and 19th centuries the planning of cities and towns and urbanistic development in the territories of Lithuania and East Europe took place due to bizarre and geometralised influence of the baroque epoch. In the 19th century scenery parks were created next to mansions in Lithuanian towns by famous scenery specialists of that time from West Europe. In the junction of 19th and 20th centuries important geopolitical processes in Lithuania and Europe took place not only in the urbanisation of cities, but also in the planning of parks and their art tendencies. Due to the growth of cities, their urbanised territories and strengthening of social attitude towards a surrounding environment, the boundaries of park art spread into the public areas of cities. At the end of the paper there is a scheme which summarises the development and influence of park structure on city development and formation .Article in Lithuanian

    Epilepsy is a disorder that has been used by dramatists in various ways over the ages and therefore highlights the views of the disorder as people saw it at the time the plays were written and performed. In the 6th century BC, links between tragedy and epilepsy were developed by Greek playwrights, especially Euripides, in Iphigenia among the Taureans and Heracles where epilepsy and madness associated with extreme violence occur together. Both Heracles and Orestes have episodes after a long period of physical exhaustion and nutritional deprivation. During the Renaissance, Shakespeare wrote plays featuring different neurological disorders, including epilepsy. Epilepsy plays a crucial part in the stories of Julius Caesar and Othello. Julius Caesar is a play about politics, and Caesar's epilepsy is used to illustrate his weakness and vulnerability which stigmatizes him and leads to his assassination. Othello is a play about jealousy, and Othello, an outsider, is stigmatized by his color, his weakness, and his 'seizures' as a form of demonic possession. In modern times, Night Mother portrays the hard life of Jessie, who lives with her mother. Jessie has no friends, her father has abandoned the family, and she has no privacy and is ashamed. Stigma and social pressures lead her to commit suicide. Henry James' novella, The Turn of the Screw, portrays a governess with dream-like states, déjà vu, and loss of temporal awareness who has been sent to the country to look after two small children and ends up killing one. This novella was turned into an opera by Benjamin Britten. Most recently, performance art has been portraying epilepsy as the reality of a personally provoked seizure. Both Allan Sutherland and Rita Marcalo have purposely provoked themselves to have a seizure in front of an audience. They do this to show that seizures are just one disability.

    Full Text Available The second half of the nineteenth century in Spain was a period characterized by a strong presence of social science, which even came to permeate the masses. Evolutionary theories and some figures such as Charles Darwin himself were present in areas far from the scientific activity proper. The use of concepts and laws of biological origin for the diagnosis and political practice against certain problematic social realities, such as crime or poverty, gave rise to theories and intellectual schools that asserted the value of evolutionary principles for the analysis of complex realities of socio-cultural inequality. The attraction for difference and the scientific method, with the possibility of observation of poverty and social inequality that industrial development and modernity put forward to the writers, added to the naturalist and biological interest a literary curiosity for the degeneration, both physical and cultural, of that unfortunate part of humanity.

    La segunda mitad del siglo XIX es un periodo caracterizado por una muy importante presencia social de la ciencia, que incluso llega a permear las clases populares. Las teorías evolucionistas y algunas figuras como la del propio Darwin aparecen así en ámbitos en principio alejados de los de la creación científica. La utilización de conceptos y leyes de origen biológico para el diagnóstico y la práctica política frente a determinadas realidades sociales problemáticas, como la delincuencia o la pobreza, dio lugar al surgimiento de teorías y escuelas intelectuales que hicieron valer los principios evolucionistas de aplicación biológica al análisis de complejas realidades de desigualdad sociocultural.

Is this a loss to Pathology? It is certainly a style of practice that has been lost. However, there is no reason to bemoan the state of Pathology in the beginning years of the 21st century. Pathology practice is outstanding at many medical centers throughout the world, including at Mount Sinai under the very able and creative leadership of Alan Schiller, who has presided over great enhancements of the department in both anatomic and clinical pathology, including significant advances in the study of diseases by molecular methods. Surgical Pathology at Mount Sinai has been led by James Strauchen, a renowned hematopathologist recruited by Schiller's predecessor, Jerome Kleinerman, and is currently directed by Ira Bleiweiss, a student of Kaneko. Other techniques and technologies have, to a degree, compensated for some of the changes since the Otani-Kaneko years and it is almost certain that advances in molecular pathology will allow for increasing sophistication in establishing diagnoses, and likely even grading and staging, probably even on blood, rather than tissue, samples. The science of Pathology will advance, as the art declines. Those who learned at Mount Sinai during the Otani-Kaneko years will, however, very likely tell you that they were privileged to have learned Pathology there and, especially, to have learned a distinct philosophy of Pathology under the guidance of caring, thoughtful, and especially gifted pathologists.

Both boreholes were logged with thermistors shortly after drilling. The shallow borehole was instrumented for 4 months with a series of resistance thermometers with satellite uplink. Surface temperature proxy data derived from an inversion of the borehole temperature profiles are compared to available multi-decadal records from weather stations and ice cores located along a latitudinal transect of the Antarctic Peninsula to West Antarctica. The LARISSA Site Beta profiles show temperatures decreasing from the surface downward through the upper third of the ice, and warming thereafter to the bed. The average temperature for the most recent year is −14.78 °C (measured at 15 m depth, abbreviated T15. A minimum temperature of −15.8 °C is measured at 173 m depth and basal temperature is estimated to be −10.2 °C. Current mean annual temperature and the gradient in the lower part of the measured temperature profile have a best fit with an accumulation rate of 1.9 × 103 kg m−2 a−1 and basal heat flux (q of 88 mW m−2, if steady-state conditions are assumed.

    The American Physical Society's part of its centennial celebration in March of 1999 decided to develop a timeline wall chart on the history of 20th century physics. This resulted in eleven consecutive posters, which when mounted side by side, create a 23-foot mural. The timeline exhibits and describes the millstones of physics in images and words. The timeline functions as a chronology, a work of art, a permanent open textbook, and a gigantic photo album covering a hundred years in the life of the community of physicists and the existence of the American Physical Society. Each of the eleven posters begins with a brief essay that places a major scientific achievement of the decade in its historical context. Large portraits of the essays' subjects include youthful photographs of Marie Curie, Albert Einstein, and Richard Feynman among others, to help put a face on science. Below the essays, a total of over 130 individual discoveries and inventions, explained in dated text boxes with accompanying images, form the backbone of the timeline. For ease of comprehension, this wealth of material is organized into five color-coded story lines the stretch horizontally across the hundred years of the 20th century. The five story lines are: Cosmic Scale, relate the story of astrophysics and cosmology; Human Scale, refers to the physics of the more familiar distances from the global to the microscopic; Atomic Scale, focuses on the submicroscopic world of atoms, nuclei and quarks; Living World, chronicles the interaction of physics with biology and medicine; Technology, traces the applications of physic to everyday living. Woven into the bottom border of the timeline are period images of significant works of art, architecture, and technological artifacts such as telephones, automobiles, aircraft, computers, and appliances. The last poster, covering the years since 1995, differs from the others. Its essay concerns the prospect for physics into the next century, and is

    During most of the 20th century, precipitation has been continuously measured by means of the so-called "pluviographs", i.e. rain gauges including a mechanical apparatus for continuously recording the depth of water from precipitation on specific strip charts, usually on a weekly basis. The signal recorded on such strips was visually examined by trained personnel on a regular basis, in order to extract the daily precipitation totals and the maximum precipitation intensities over short periods (from a few minutes to hours). The rest of the high-resolution information contained in the signal was usually not extracted, except for specific cases. A systematic recovering of the entire information at high temporal resolution contained in these precipitation signals would provide a fundamental database to improve the characterization of historical rainfall climatology during the previous century. The Department of Land Engineering of the University of Cagliari has recently developed and tested an automatic software, based on image analysis techniques, which is able to acquire the scanned images of the pluviograph strip charts, to automatically digitise the signal and to produce a digital database of continuous precipitation records at the highest possible temporal resolution, i.e. 5 to 10 minutes. Along with that, a significant amount of daily precipitation totals from the late 19th and the 20th century, either elaborated from pluviograph strip charts or simply derived from bucket rain gauges, still exists in paper form, but it has never been digitalized. Within a project partly-funded by the Operational Programme of the European Union "Italia-Francia Marittimo", the Regional Environmental Protection Agency of Sardinia and the University of Cagliari will recover both the high-resolution rainfall signals and the older time series of daily totals recorded by a large number of pluviographs belonging to the historical monitoring networks of the island of Sardinia.

    Full Text Available The wrong management of watering in the highest zones of the Mendoza northern oasis, the topography of the terrain and the deficient drainage, together with neotectonics phenomena, but mostly a dramatic and progressive increase of the Rio Mendoza flow volume originated the expansion of the wetlands area at the NE of the city of Mendoza at the turn of the 18th century, while in previous centuries it had retracted to a minimum. The area grew until reaching the dimension of large wetlands in the lowest oasis zones, resulting from a larger runoff and soil saturation by the rise of the phreatic layers. This situation remained throughout the 19th century, affecting the extension and use of the available land for human activity. The purpose of this study was to research this process that culminated in 1930 with the partial desiccation of the area. We have given particular importance to the influence of the climatic fluctuations in the Cordillera de los Andes and to the consequent variations of the Rio Mendoza flow volume in this process. For the analysis we used snowfall series at the cordillera and flow volume of the Rio Mendoza, built by Prieto (2009 with documental data. We analyzed which were the mediate and immediate consequences of the growth and later desiccation of the wetlands over the environment and its present repercussion on the ecosystem (salinization, poor soil drainage, soil alkalinization, sedimentation. In addition, we have also worked over georeferenced historic charts that partially reflect the behavior of the Cienaga del Bermejo during the 18th, 19th and 20th centuries. This behavior characterized by "growth pulses" and retraction moments is reflected in the analyzed charts, where those moments of major growth coincide with cycles of bigger snowstorms and larger flow volume in the Rio Mendoza.

With the analysis of historical periods that are highlighted in the research, general trends in the changing of paradigms about Russian historical development were concluded, which were translated to mass historical consciousness from the beginning of the 18th century up to 1917. The periods were closely connected with the specific political, historical and economic changes in Russian Empire and with the dominance of certain textbooks during this time. The books were selected because of a number of factors: their inclusion to the school curriculum, the number of publications (10 and more, the equal number of textbooks devoted to different historical periods. For the analysis were used 19 textbooks, schoolbooks for different courses of secondary schools and primary schools. All the sources of educational literature were grouped into two concepts - officially-state (patriotic and the liberal. Each publication was highlighted the dominant concept as a base for the whole textbook. There is also a characteristic of the concepts that are presented chronologically. The analysis represents school history books as an important source for the formation of state policy in the representing of Russian history, and, that is more important, for creation of the concept of the state of Russian history.

  17. Defense Industry of the Russian Federation at the End of 20th-Beginning of the 21st Century

    Full Text Available In the developed countries claiming for global leadership permanent military and industrial complexes were formed. These complexes produce high-tech products and play the key system-forming role in the economies of their states. Country’s position in world economy as well as its position at the weapons and military equipment market depends on the military and industrial complexes development. At the end of the 20th century, there had been great changes in the military and industrial complex of the Russian Federation. Drastic remission and demerger accompanied these changes unlike those in the Unites States and Western Europe. These processes were determined by inconsiderate defense conversion, reduction of expenses and the loss of weapons and military equipment production. At the beginning of the 21st century, Russian Federation government has changed its attitude towards the military and industrial complex. Main directions of surmounting the crisis were found through creation of military and industrial corporations, increase of state defense order in the favor of national Armed Forces. Development of state-owned corporations and significant increase in financial allocations for state defense order promoted the growth of military and industrial companies’ activity and rise in weapons and military equipment export. All above-listed processes of Russian military and industrial complexes predetermined the scientific and pragmatic interest for this research.

  18. Views of Europe among Serbian political and cultural elite in late 20th and early 21st century

    2006-01-01

    Full Text Available On the basis of his own previous research the author examines views of Europe held by the Serbian political and cultural elite in the late 20th and early 21st century. Unable to meet the challenges of the historical moment, this elite has brought Serbia into open conflict with its closest neighbors and exposed its citizens to international sanctions. War-mongering propaganda of the major state-controlled media was developing feelings of xenophobia and frustration among citizens. The collusion between authoritarian government and war profiteers was systematically destroying the lives of Serbian citizens, bringing them to the brink of material impoverishment and spiritual misery. The process of dissolution of the common Yugoslav state is coming to its end in the first decade of this century. Just as it lacked wisdom political will or strength to prevent armed conflicts and crimes, the Serbian elite today is unable to condemn war crimes, to face disastrous consequences of its own policies, and to help Serbian citizens find their way to prosperity.

  19. Fighting for Anatomy. Overview regarding two prestigious Romanian anatomists of the 20th century: Victor Papilian and Grigore T. Popa.

    During many centuries, the progress of Anatomy was based on the perseverant and laborious activities done by anatomists. Their work can be considered as a fight for Anatomy. A particular problem arouse when this fight is excessively done and it limits the ability to correctly analyze the contribution made by other scientists in the same domain. This situation was identified at different personalities who lived in the same time and were involved in the same fundamental field of research. If, theoretically, the similarities between scientists should get them closer, in order to have a better communication, the antagonisms can lead them to rivalry. Our paper exemplifies a historical case in which the personages are Victor Papilian (1888-1956) and Grigore T. Popa (1892-1948). The resemblances between these two famous Romanian anatomists from the first half of the 20th century induced an evident scientific rivalry. Papilian and Popa brought a significant contribution in anatomy. Each of them was very much appreciated by his students. It is interesting that both of them had achievements in literature. We present the reasons of their disagreement and its consequences. Paradoxically, not the contrasts, but the resemblances between their strong characters produced a sort of animosity between them. This attitude diminished in time and their successors - Ioan Albu from the Cluj Faculty of Medicine and Ion Iancu from the Jassy Faculty of Medicine - had a long lasting and successful cooperation.

  3. Migrations from the Gora region at the end of the 20th and the beginning of the 21st century

    Full Text Available In this paper I will analyze economic and political migration in the Gora region at the end of the 20th and in the first decade of the 21st century. It is my intent to consider and explain their cause and their intensity and scope. In short, I view the socioeconomic and political dimension of these migrations from an ethnological and anthropological point of view. The economic and political migrations from the Gora region at the end of the 20th and the beginning of the 21st century represent the continuation of earlier migrations, albeit more intensive and larger in scope (whole families are migrating. There migrations can be viewed as the effects of political changes in Kosovo, as well as the socioeconomic crisis of the 1990’s. There are no fixed boundaries between these types of migrations, and the only truly stand out examples are the cases in which people migrated for safety reasons. A certain type of migration can be identified based on the terminology used by the interlocutors. I have encountered the terms “banishment” and “displacement” in the narrative discourse of my interlocutors. These terms are used to describe the migrations from Gora during the 1999 war, as well as immediately after. The differences between economic and political migrants can be gouged from other factors such as going to Gora during vacations and holidays as well as investing money into real-estate in the region. Individuals who emigrated from Gora because they feared for their and the loves of their families go to Gora rarely (to attend funerals for example and are not currently thinking of investing unlike those who had left Gora as economic migrants. There are no differences when it comes to where people migrate to for different reasons. Places of migration can, however, be indicative of the form of migration in the sense of whether people migrated to a foreign country or not. One can turn into the other due to the changing of state borders. Thus

    Full Text Available A strengthening of the equatorward temperature gradient in the upper troposphere/lower stratosphere (UTLS, at subtropics and midlatitudes, is consistently reproduced in several modelling studies of the atmospheric response to the increase of greenhouse gas radiative forcing. Some of those studies suggest an increase of the baroclinicity in the UTLS region because of the enhanced meridional temperature gradient.

    This study presents observational evidence of an increase of the baroclinic wave components of UTLS circulation (UTLS wave baroclinicity, during the second half of the 20th century. The evidence is given by significant positive trends in the energy of baroclinic normal modes of the NCEP/NCAR reanalysis, and significant positive trends in the UTLS eddy available potential energy of the NCEP/NCAR, ERA-40, NCEP-2 and JRA-25 reanalyses. Significant positive trends in the frequency of double tropopause events in radiosonde data are also interpreted as a manifestation of an increase of the UTLS wave baroclinicity.

    Full Text Available Topics of ethnological research, as well as scientific discourse in general often represent the mirror of social reality. This paper researches the ways in which dealing with death and current ethnological approaches in Serbian ethnology during the second half of the 20th century, reflect the Zeitgeist. The intensity and the quality of interests for this important anthropological theme varied during the researched period, wherefore it is possible to differentiate two types of works and authors: those who write about funeral rituals, and those who 'read' them. From 1980s until nowadays there are three subgroups of contributions to this theme that reflect critical moments of the contemporary Serbian history. The issues raised in this paper are the following: The way in which state/society regards death the way in which it structures death, the way in which it gives meaning to death, as well as the usage of death for political purpose and the constant effort of civilization to repress it into oblivion.

  6. The death of "Till death us do part": the transformation of pair-bonding in the 20th century.

    2002-01-01

    During the last half of the 20th century within Western civilization, for the first time in human history, divorce replaced death as the most common endpoint of marriage. In this article I explore the history of this death-to-divorce transition, the forces associated with the transition, and what the transition may have revealed about the human capacity for monogamous, lifelong pair-bonding. The impact and consequences of the transition for the generations that came of age during it and immediately afterwards are examined, with particular attention to the emergence of new, alternative pair-bonding structures such as cohabitation and nonmarital co-parenting. The article highlights the inability of the dichotomous marriage-versus-being-single paradigm to encompass the new pair-bonding structures and the normalizing of divorce. Precepts for a new, more encompassing, veridical and humane pair-bonding paradigm are presented, and some of their implications for social policy, family law, social science, and couple and family therapy are elaborated.

    Full Text Available A process-based ecosystem model, the Dynamic Land Ecosystem Model (DLEM, was applied to evaluate the effects of cropland expansion on terrestrial carbon fluxes and pools in South and Southeast Asia in the 20th century. The results indicated that cropland expansion in both regions has resulted in a release of 18.26 Pg C into the atmosphere in the study period. Of this amount, approximately 23 % (4.19 Pg C was released from South Asia and 77 % (14.07 Pg C from Southeast Asia. More land area was converted to cropland but less carbon was emitted in South Asia than in Southeast Asia, where forest biomass and soil carbon are significantly higher. Carbon losses in vegetation, soil organic matter, and litter carbon pools accounted for 15.09, 2.01, and 1.60 Pg C, respectively. Significant decreases in vegetation carbon occurred across most regions of Southeast Asia due to continuous cropland expansion and depletion of natural forests. Our study also indicated that it is important to take into account the land use legacy effect when evaluating the contemporary carbon balance in terrestrial ecosystems.

    Louis Nico Marie (L. N. M.) Duijsens (Duysens) was one of the giants in the biophysics of photosynthesis. His PhD thesis "Transfer of Excitation Energy in Photosynthesis" (Duysens, 1952) is a classic; he introduced light-induced absorption difference spectroscopy to photosynthesis research and proved the existence of reaction centers, introducing advanced methods from physics to understand biological processes. Further, it is his 1959-1961 seminal work, with Jan Amesz, that provided evidence for the existence of the series scheme for the two light reactions in oxygenic photosynthesis. In one word, he was one of the master biophysicists of the 20th century-who provided direct measurements on many key intermediates, and made us understand the intricacies of photosynthesis with a simplicity that no one else ever did. We present here our personal perspective of the scientist that Lou Duysens was. For an earlier perspective, see van Grondelle and van Gorkom (Photosynth Res 120: 3-7, 2014). PMID:27039907

  9. Floodplain lakes as an archive for the metal pollution in the River Elbe (Germany) during the 20th century

    International Nuclear Information System (INIS)

    Highlights: • A floodplain sediment sequence (about 1900–1998) was analyzed on potentially harmful elements. • High sediment contamination by industry restricted to unstable metal binding forms. • After closure of industries (1990) the level of floodplain contamination perpetuates. • Antagonistic binding forms indicate a sensitive equilibrium in sediments. • Floodplain management requires the stabilization of the environmental equilibrium. - Abstract: The German Elbe River floodplains rank under the most polluted areas in Europe. A sudden concentration increase of potentially harmful elements (PHEs) is documented in sediment profiles of Elbe bayous. The increase is dated to the mid of the 20th century (137Cs) and indicates industrialization of the former German Democratic Republic (GDR) as the source of intense pollution. The collapse of the GDR and the industries in the 1990s is traced by a concentration decrease in young sediments. The contamination is restricted to an increase of unstable binding forms; the hydroxide binding form is predominant. The geogenic concentration portions are of normal level and remain stable throughout the profiles (0–2 m). The equilibrium of contradictory binding forms in the sediments makes it mandatory not to interfere with the thermodynamic conditions and to keep the Elbe floodplain as an undisturbed ecological system

  10. Predicting U.S. food demand in the 20th century: a new look at system dynamics

    1998-08-01

    The paper describes a new methodology for predicting the behavior of macroeconomic variables. The approach is based on System Dynamics and Fuzzy Inductive Reasoning. A four- layer pseudo-hierarchical model is proposed. The bottom layer makes predications about population dynamics, age distributions among the populace, as well as demographics. The second layer makes predications about the general state of the economy, including such variables as inflation and unemployment. The third layer makes predictions about the demand for certain goods or services, such as milk products, used cars, mobile telephones, or internet services. The fourth and top layer makes predictions about the supply of such goods and services, both in terms of their prices. Each layer can be influenced by control variables the values of which are only determined at higher levels. In this sense, the model is not strictly hierarchical. For example, the demand for goods at level three depends on the prices of these goods, which are only determined at level four. Yet, the prices are themselves influenced by the expected demand. The methodology is exemplified by means of a macroeconomic model that makes predictions about US food demand during the 20th century.

  11. 20th Century trends and budget implications of trihalomethanes and dihalomethanes inferred from North GRIP firn air

    2006-01-01

    Full Text Available Four trihalomethane (THM; CHCl3, CHBrCl2, CHBr2Cl and CHBr3 and two dihalomethane (DHM; CH2BrCl and CH2Br2 trace gases have been measured in air extracted from polar firn collected at the North Greenland Icecore Project (NGRIP site. CHCl3 was also measured in firn air from Devon Island (DI, Canada, Dronning Maud Land (DML, Antarctica and Dome Concordia (Dome C, Antarctica. All of these species are believed to be almost entirely of natural origin except for CHCl3 where anthropogenic sources have been reported to contribute ~10% to the global burden. A 2-D atmospheric model was run for CHCl3 using reported emission estimates to produce historical atmospheric trends at the three firn sites, which were then input into a firn diffusion model to produce concentration depth profiles that were compared against the measurements. The anthropogenic emissions were modified in order to give the best model fit to the firn data at NGRIP, Dome C and DML. As a result, the contribution of CHCl3 from anthropogenic sources, mainly from pulp and paper manufacture, to the total chloroform budget appears to have been considerably underestimated and was likely to have been close to ~40% at the maximum in atmospheric CHCl3 concentrations around 1990, declining to ~19% at the beginning of the 21st Century. We also show that the atmospheric burden of the brominated THM's in the northern hemisphere have increased over the 20th Century while CH2Br2 has remained constant over time implying that it is entirely of natural origin.

    Freshwater lakes play a key role in the global carbon cycle as sinks (organic carbon sequestration) and sources (greenhouse gas emissions). Understanding the carbon cycle response to environmental changes is becoming a crucial challenge in the context of global warming and the preponderance of human pressures. We reconstructed the long-term (1500 years) evolution of trophic functioning of the benthic food web, based on methanotrophic ancient DNA and chironomid isotope analyses). In addition, human land use is also reconstructed in three different lakes (eastern France, Jura Mountains). Our findings confirm that the benthic food web can be highly dependent on methane-derived carbon (up to 50% of the chironomid biomass) and reveal that the activation of this process can correspond to a natural functioning or be a consequence of anthropic perturbation. The studied lakes also showed a similar temporal evolution over the last century with the disappearance of the profundal aquatic insects (Chironomidae, Diptera), considered as keystone for the whole lake food web (e.g., coupling benthic-pelagic), inducing a potential collapse in the transfer of methane to top consumers. This functional state, also called the dead zone expansion, was caused by the change in human land-use occurring at the beginning of the 20th century. The strong modification of agro-pastoral practices (e.g., fertilization practices, intensive grazing, and sewage effluent) modified the influx of nutrients (by diffuse and/or point-source inputs) and induced a significant increase in the trophic status and organic matter sedimentation to reach unprecedented values. Further studies should be planned to assess dead zone expansion and, according to the regime shift theory, to provide environmental tipping points for sustainable resource management.

  13. Stevens’ forgotten crossroads: The divergent measurement traditions in the physical and psychological sciences from the mid-20th century

    Directory of Open Access Journals (Sweden)

    Joshua A McGrane

    2015-04-01

    Full Text Available The late 19th and early 20th Centuries saw the consolidation in physics of the three main traditions that predominate in discussions of measurement theory. These are: (i the systematic tradition pioneered by Maxwell; (ii the representational tradition pioneered by Campbell; and (iii the operational tradition pioneered by Bridgman (1927. These divergent approaches created uncertainty about the nature of measurement in the physical sciences and provided Stevens (1946 with an opportunity and rationale to, in effect, reinvent the definition of scientific measurement. Stevens appropriated the representational and operational traditions as the sole basis for his definition of measurement, excluding any place for the systematic approach. In committing to Stevens’ path, the psychological sciences were blinded to the advances made in metrology, the establishment of the International System (SI and the standard units contained within this system. These advances were only possible due to the deep conceptual and instrumental connections between the system of physical units and the body of physical theory and laws developed over the preceding centuries. It is argued that if the psychological sciences are to ever achieve equivalent methodological advances, they must bridge this ‘metrological gap’ created by Stevens’ measurement crossroads and understand the ways in which the systematic approach advanced measurement. This means that psychological measurement needs to be de-abstracted, rid of operational rules for numerical assignment and set upon a foundation of quantitative theory, definition and law. In the absence of such theoretical foundations, claims of measurement in the psychological sciences remain a methodological chimera.

    2007-06-01

    The start of the 19th century saw the enthusiasm of the previous one for mouth-to-mouth ventilation (MMV) dissipated. To inflate the lungs of the asphyxiated, the Royal Humane Society in the United Kingdom had recommended bellows since 1782. Principal determinants for change were aesthetic distaste for mouth-to-mouth contact and the perceived danger of using expired air, although MMV survived in the practice of some midwives. Following the 1826-9 investigations of Jean-Jacques Leroy d'Etiolles then François Magendie, all positive pressure ventilation methods were generally abandoned, after 1829 in France, and 1832 in the UK; but not chest compressions. During the next quarter century, rescuers lost understanding of the primary need for "artificial respiration", apart from researchers such as John Snow and John Erichsen, until Marshall Hall's "Ready Method" heralded the second half-century's various methods of negative pressure ventilation. Some of those methods continued in use until the 1940s. Sporadic anecdotal cases of MMV rescues were documented throughout. In the 20th century, inadequate mechanical inhalators were also tried from 1908, while obstetricians devised indirect methods of expired air ventilation (EAV). Anaesthetists in the 1940s, such as Ralph Waters, Robert Dripps, and the pair, Robert Macintosh and William Mushin, described the usefulness of MMV, and James Elam was "re-discovering" it. Following World War II, "Cold War" concerns stimulated research at the Edgewood Medical Laboratories in Maryland in the United States into the possibilities of MMV, and Elam et al confirmed and expanded on brief experiments at Oxford (United Kingdom) on the efficacy of mouth-to-tube EAV. Studies, 1957-9, by Archer Gordon, Elam and especially Peter Safar resulted in the resolution of previous airway problems, established the primacy of MMV, and incorporated it into an integrated system for basic cardiopulmonary resuscitation. Ready adoption of MMV in the US was

    In the Netherlands nation-wide databases are available with about 10 million records of occurrences of vascular plant species in the 20th century on a scale of approximately 1 km{sup 2}. These data were analysed with a view to identifying relationships between changes in botanical biodiversity and climatic and other environmental factors. Prior to analysis the data were corrected for several major forms of survey bias. The records were broken down into three periods: 1902-1949, 1975-1984 and 1985-1999. Using multiple regression analysis, differences between successive periods were related to plant functional characteristics as explanatory variables. Between the periods 1902-1949 and 1975-1984 there were small but significant increases in the presence of both thermophilic ('warm') and psychrophilic ('cold') species. However, in the final decades of the 20th century there was a marked increase in thermophilic species only, coinciding with the marked increase in ambient temperature observed during this period, evidence at least of a rapid response of Dutch flora to climate change. Urbanisation was also examined as an alternative explanation for the increase in thermophilic plant species and was found to explain only 50% of the increased presence of such species in the final decades of the 20th century. Besides temperature-related effects, the most important change during the 20th century was a strong decline in oligotrophic and a marked increase in eutrophic plant species.

    The variation in surface wetness index (SWI), which was derived from global gridded monthly precipi- tation and monthly mean surface air temperature datasets of Climatic Research Unit (CRU), from 1951― 2002 over global land was analyzed in this paper. The characteristics of the SWI variation in global continents, such as North America, South America, Eurasia, Africa, and Australia, were compared. In addition, the correlation between the SWI variation of each continent (or across the globe) and the large-scale background closely related to SST variations, which affects climate change, was analyzed. The results indicate that the SWI variation shows distinct regional characteristics in the second half of the 20th century under global warming. A drying trend in the last 52 years occurred in Africa, Eurasia, Australia and South America, most obviously in Africa and Eurasia. North America shows a wetting trend after 1976. A 30-year period of dry-wet oscillation is found in South America and Australia; the latest is in a drying period in two regions. The results also revealed that global warming has changed the dry-wet pattern of the global land. South America and Australia have a drying trend despite in- creases in precipitation. This indicates that increases in surface air temperature cannot be ignored in aridification studies. Global dry-wet variation is closely related to large-scale SST variations: the drying trend in Africa and Eurasia and the wetting trend in North America are correlated with Pacific Decadal Oscillation (PDO); the interdecadal oscillation of SWI in South America and Australia is consistent with the interdecadal variation in Southern Oscillation Index (SOI).

    The mean and extreme matrices of the monsoon rainfall in India not only play an important role in depicting the global monsoon climate, but also their spatiotemporal patterns influence the socio-economic profile of a major proportion of the country's huge population. Given the reported conflicting trends at the global and national scales, the present study investigates the 20th century (1901-2004) changes in monsoon rainfall of India, particularly focusing the indices developed by the Expert Team on Climate Change Detection and Indices (ETCCDI) to facilitate a global comparison. Result of this comprehensive analysis, which includes the response of fifteen indices over two study periods (i.e., 1901-1940 and 1961-2004), indicates clear signals of change with respect to the period and region of study and the choice of the ETCCDI indices. While wet day frequency, low-to-moderate events and consecutive wet days (CWD) exhibit a prominent transition from a pre-1940 wetting to a post-1960 drying tendency over a large part of the central-north India (CNI), both the wet and dry extremes have occurred in a spatially less consistent manner during the recent decades. For consecutive dry days (CDD), the reported less clear global signals could be related to the timescale of analysis, as our sub-seasonal scale results display consistent changes compared to that of the seasonal and annual scales. The Palmer Drought Severity Index (PDSI) provides clear indications of a post-1960 non-stationarity, showing changes in the mean as well as variance. Based on the partial Mann-Kendall test (PMK), some of the identified rainfall trends during 1961-2004 are found to be influenced more by the tropical Indian Ocean sea surface temperatures than the El Niño-Southern Oscillation index. These results have important implications for formulating the water resource management strategy, particularly over the drying central and northern parts of the country.

    Full Text Available Completion of the human genome sequencing has stirred the whole scientific community in many ways. Apart from deciphering the biological meaning of sequence-language written in three billion letters, which may take a century, scientists are essentially confronted with many challenges. It will not only revolutionise the field of genetics in terms of knowing ourselves better but also help us tremendously in identifying genetic diseases and preventing them by predicting and finding cure for them. Integration of medicine and molecular biology is expected to lead to better health care systems by preventing people from becoming sick by following a suggested way of life based on individual genetic makeup. Recently developed technologies are helping scientists to analyse the genome at an unprecedented scale and understand the function of various genes, influence of environmental factors on them and their correlation with human behaviour. Availability of human genome sequence has raised several ethical and moral questions regarding the confidentiality of the sharing of genomic information as well as whether society is ready for this. Real challenge, after knowing functions of all the genes, would be to make use of this knowledge for the welfare of human beings with the aim to enhance the quality of human life.

  8. Changes in the geodiversity of Dutch peatlands inferred from 19th and 20th century landscape paintings

    Geodiversity is the natural and cultural range of geological, geomorphological and soil features. We analysed the large database of 19th and early 20th century paintings of Simonis and Buunk (www.Simonis-Buunk.com) to track changes in the geodiversity of Dutch peatlands since pre-photographic times. Peat dominated in two of the eight main landscapes of the Netherlands: the Lowland peats in the Holocene west and the Highland peats in the sandy Pleistocene eastern parts. Painters were mainly attracted by the lowland peats. Since more than thousand years, peat plays a major role in Dutch military security, economy, ecology and cultural life. Natural variety and cultural use resulted in a geodiversity that is unique in Europe. There are more than 100 place names with 'veen' (= peat), and surnames with 'veen' are common. Proof of the exploitation of peat for salt and fuel exists from the Roman times onwards. In the 9th century, peatlands were drained and reclaimed for growing wheat. Already in the 11th century, it was necessary to build dikes to prevent flooding, to control waterlevels to avoid further oxidation, and to convert landuse to grassland. But subsidence continued, and in the 14th century windmills were needed to drain the lands and pump the water out. In the 16th century industrial peat exploitation fuelled the rise of industries and cities. All this draining and digging caused the peat surface to shrink. The few remaining living peats are conserved by nature organisations. Geodiversity and landscape paintings In the peat landscapes, popular painting motives were high water levels, the grasslands of the 'Green Heart', the winding streams and remaining lakes. The paintings of landscapes where peat had been removed, show watermanagement adaptations: wind mills, different water levels, canals made for the transport of fuel, bridges, tow paths and the 'plassen', i.e. the lakes left after peat exploitation.

    Full Text Available The aim of this article is to examine the relations between the old and the new in the context of 20th-century Slovenian music. The question about the old and the new is seen not only as a question of different facets of an age-old opposition, but also as a complex issue of the epistemological contextualization of those different facets. Centered on the main historiographical entries – the avant-garde, modernity, traditionalism, and post-modernity –, the outline of the 20th-century Slovenian musical culture endeavors to point out what is a common problem of the Western musical heritage from the past century: the problem of defining constituents of the old and the new within different epistemological contexts.

    2007-01-01

    Progress in the attribution of climate warming in China for the 20th century is summarized. Three sets of climate model experiments including both coupled and uncoupled runs have been used in the attribution analyses. Comparison of climate model results with the observations proves that in the 20th century, especially in the recent half century, climate warming in China is closely related to the increasing of the anthropogenic emissions of greenhouse gases, while sulfate aerosol should also have contributions. When both external forcing and natural forcing agents are prescribed, coupled climate models have better results in producing the observed variation of temperature in China. The role of oceanic forcing is also emphasized in the attribution analyses. The observed climate warming of China in the 1920s could not be reproduced in any set of climate model simulations.

  11. Extension of the SIM Hydrometeorological Reanalysis Over the Entire 20th Century by Combination of Observations and Statistical Downscaling

    The SAFRAN-ISBA-MODCOU (SIM) system is a combination of three different components: an atmospheric analysis system (SAFRAN) providing the atmospheric forcing for a land surface model (ISBA) that computes surface water and energy budgets and a hydrological model (MODCOU) that provides river flows and level of several aquifers. The variables generated by the SIM chain constitute the SIM reanalysis and the current version only covers the 1958-2012 period. However, long climate datasets are required for evaluation and verification of climate hindcasts/forecasts and to isolate the contribution of natural decadal variability from that of anthropogenic forcing to climate variations. The aim of this work is to extend of the fine-mesh SIM reanalysis to the entire 20th century, especially focusing on temperature and rainfall over France, but also soil wetness and river flows. This extension will first allow a detailed investigation of the influence of decadal variability on France at very fine spatial scales and will provide crucial information for climate model evaluation. Before 1958, the density of available observations from Météo-France necessary to force SAFRAN (rainfall, snow, wind, temperature, humidity, cloudiness) is much lower than today, and not sufficient to produce a correct SIM reanalysis. That's why is has been decided to use the available atmospheric observations over the past decades combined to a statistical downscaling algorithm to overcome the lack of observations. The DSCLIM software package implemented by the CERFACS and using a weather typing based statistical methodology will be used as statistical downscaling method to reconstruct the atmospheric variables necessary to force the ISBA-MODCOU hydrological component. The first stage of this work was to estimate and compare the bias and strengths of the two approaches in their ability to reconstruct the past decades. In this sense, SIM hydro-meteorological experiments were performed for some recent

    Full Text Available Two simulations with a regional climate model are analyzed for climatic changes between the late 20th century and a pre-industrial period over central and southern South America. The model simulations have been forced with large-scale boundary data from the global simulation performed with a coupled atmosphere-ocean general circulation model. The regional simulations have been carried out on a 0.44° × 0.44° grid (approx. 50 km × 50 km horizontal resolution. The differences in the external forcings are related to a changed greenhouse gas content of the atmosphere, being higher in the present-day simulation.

    For validation purposes the climate model is analyzed using a five year long simulation between 1993 and 1997 forced with re-analysis data. The climate model reproduces the main climatic features reasonably well, especially when comparing model output co-located with observational station data. However, the comparison between observed and simulated climate is hampered by the sparse meteorological station network in South America.

    The present-day simulation is compared with the pre-industrial simulation for atmospheric fields of near-surface temperatures, precipitation, sea level pressure and zonal wind. Higher temperatures in the present-day simulation are evident over entire South America, mostly pronounced over the southern region of the Andes Mountains and the Parana basin. During southern winter the higher temperatures prevail over the entire continent, with largest differences over the central Andes Mountains and the Amazonian basin.

    Precipitation differences show a more heterogeneous pattern, especially over tropical regions. This might be explained by changes in convective processes acting on small scales. During southern summer wetter conditions are evident over the Amazonian and Parana basin in the present-day simulation. Precipitation increases are evident over Patagonia together with decreases to the

    Full Text Available Comparison of single-forcing varieties of 20th century historical experiments in a subset of models from the Fifth Coupled Model Intercomparison Project (CMIP5 reveals that South Asian summer monsoon rainfall increases towards the present day in Greenhouse Gas (GHG-only experiments with respect to pre-industrial levels, while it decreases in anthropogenic aerosol-only experiments. Comparison of these single-forcing experiments with the all-forcings historical experiment suggests aerosol emissions have dominated South Asian monsoon rainfall trends in recent decades, especially during the 1950s to 1970s. The variations in South Asian monsoon rainfall in these experiments follows approximately the time-evolution of inter-hemispheric temperature gradient over the same period, suggesting a contribution from the large-scale background state relating to the asymmetric distribution of aerosol emissions about the equator. By examining the twenty-five available all-forcings historical experiments, we show that models including aerosol indirect effects dominate the negative rainfall trend. Indeed, models including only the direct radiative effect of aerosol show an increase in monsoon rainfall, consistent with the dominance of increasing greenhouse gas emissions and planetary warming on monsoon rainfall in those models. For South Asia, reduced rainfall in the models with indirect effects is related to decreased evaporation at the land surface rather than from anomalies in horizontal moisture flux, suggesting the impact of indirect effects on local aerosol emissions. This is confirmed by examination of aerosol loading and cloud droplet number trends over the South Asia region. Thus while remote aerosols and their asymmetric distribution about the equator play a role in setting the inter-hemispheric temperature distribution on which the South Asian monsoon, as one of the global monsoons, operates, the addition of indirect aerosol effects acting on very local

    The tsunami generated by the 1st November 1755 (Mw ~8.5) earthquake off Portugal affected mainly the coasts of the Iberian Peninsula and Northwest Morocco, and was observed in some places on the North Atlantic coasts, towards the West Indies, but also towards Ireland and the Great Britain, in Cornwall. However, no evidence of observation were found along French Atlantic coastline so far. In a first step, to determine whether there could be effects due to tsunamis on the French coastline, we conducted a study to search for actual tsunamis signals in all historical tide gauge stations of the French Atlantic coast available during the 20th century, specifically for the 1969 and 1975 tsunamis that were well observed in Portugal. Because many recordings are available from the French Hydrographic Service in La Rochelle (west French Atlantic coastline), we focus our study on this harbor. The analysis of these historical tide gauge data shows no evidence for tsunamis in La Rochelle, neither in 1969 or in 1975. Then, to confirm this lack of tsunami, we simulate the tsunamis from the 1969 and 1975 sources, using non linear shallow water equations and a series of imbricated bathymetric grids focusing to the French coastline, and then towards the harbor of La Rochelle: the modeling results confirm unnoticeable amplitudes. In the following step, tsunamis from three different scenarios for the 1755 earthquake have been similarly modeled to estimate the impact of such a tsunami on the French Atlantic coast, with a focus on La Rochelle harbor. The results show that, while the harbor is well protected (amplitudes computed on a synthetic tide gage in the harbor do not exceed 20 to 30 cm crest-to-trough) several areas may have undergone a more important, yet moderate impact, from 0.5 to 1 m, especially in the western part of the island of Ré and the northern coast of the island of Oléron. This may have caused possible local inundations in lowland areas, all the more since the tide

    Full Text Available The business model and strategic position of Quebec's rural foundries at the beginning of the 20th century is virtually unknown. Inferences have been made based on pictorial and oral data sources. This data reveals that successful rural foundries were, in essence, confined to producing and selling agricultural tools to local farmers on an as-needed basis, because large urban foundries were already mass-producing domestic and industrial objects. In contrast, use of detailed accounting records and advertising publications of three rural foundries over the 1900 to 1914 period provides a clearer picture of the production and of the clientele of those rural foundries. Analysis of these sources suggests that the strategic business model of rural foundries was much more elaborate than the existing literature posits. Rural owner-managers of the early 20th century were sophisticated strategists, marketers, and operators.

    During the first half of the 20th century, the issue of sex education for young people was the topic of virulent debate. Increasing proposals for sex education in schools, along with lectures and information leaflets, were quickly opposed by Catholic circles, which did not reject sex education in principle but sought to control its form and content. Yet no matter which form or content was chosen, sex education remained underpinned by considerations about the future of the population and the s...

    Full Text Available On the basis of the analyzed demographic data for the last decade of the 20th century and the beginning of the 21st century, one could conclude that the most significant characteristics of the population of Vojvodina are: slow demographic increase; negative population growth; more and more unfavourable age structure; increase in the decision to remain single; relatively low level of urbanization, a very heterogeneous national composition of the population; acceptance of low reproductive norms in the majority of the population; and a very probable depopulation in the future. The discussed demographic features characteristic for Vojvodina as a whole are also present in most of the smaller territorial-administrative units like districts and muinicipalities. Their population is also characterized by the negative population growth, low birthrate and fertility, high general mortality-rate as well as by a very advanced process of demographic ageing. The analysis about the demographic situation in Vojvodina was primarily based on the data from the 1991 and 2002 censuses, as well as on the data of the vital statistics for that inter-census period.

  3. The decline of winter monsoon velocity in the South China Sea through the 20th century: Evidence from the Sr/Ca records in corals

    A modern massive Porites coral was collected from the Longwan Bay (19??20???N, 110??39???E) on the east coast of the Hainan Island, China. The coral was sectioned vertical to the growth axis into discs of double density-bands representing annual growth. The samples were analyzed for the Sr/Ca ratio by inductively coupled plasma atomic emission spectrometry. The history of winter sea-surface temperature (SST) is reconstructed using the Sr/Ca ratio in winter bands of corals. The winter SST at Xisha in the middle of the South China Sea (SCS) is weakly correlated with the instrument-measured winter monsoon velocity (WMV) with a correlation coefficient of 0.19. The winter SST data from corals at Longwan Bay, Hainan, in the northern SCS are moderately correlated with the WMV (r = 0.40). Interestingly we found that the difference of winter SSTs between the two sites (Xisha and Longwan Bay, Hainan) (the X-H index) is significantly negatively correlated with the WMV (r = - 0.73). This negative correlation may be related to the intrusion of the warm Kuroshio Current into the SCS through the Luzon Strait promoted by the strong northeastern monsoon winds in the winter. Using the relationship between our coralline data and observed WMV, the calculated winter monsoon velocity (WMVc) was obtained for 87??years. This data set in combination with the instrument-measured data between 1993 and 1998 generate a record of WMVc for a period of 93??years from 1906 to 1998. The WMVc in the 20th century shows significant interannual and decadal variability with a trend of persistent decline in the whole 20th century at the rate of decrease of - 0.02 (m/s)/a. The lowest wind velocity occurred during the last two decades of the 20th century. The WMVc has decreased significantly by about 30% from the early to the late of 20th century. The 20th century decline of winter monsoon velocity evidenced from the SCS coral records is consistent with the atmosphere-ocean general circulation models

    This study reconstructs a series of droughts and high flow volumes of the Bermejo River from the 17th to 20th century based on a content analysis of historic documentary evidence, which is calibrated with instrumental climate data. The historic data series shows an increase in the frequency of extraordinarily high waters beginning in the 19th century and a significant decrease in extreme droughts beginning in 1890. The data are compared to variations in the Mendoza River for the same period, which show that there was a long-standing lack of correlation between the rivers.

    Full Text Available This study looks into the history of the Jewish community in Ukrainian governorates within the Russian Empire in the 19th century. The article examines the social-economic state of the Jewish community in Ukrainian governorates in the 19th century and analyzes preconditions for the creation of national Jewish public organizations in the Russian Empire in the early 20th century. At the turn of the century, there formed a specific social structure of the Jewish population in Ukrainian governorates within the Russian Empire. Even a superficial analysis and comparison of the social structure of the Jewish and other ethnoses lets us draw a conclusion about the prevalence of representatives of the merchant, craftsman, and usurer social groups among the Jews of the region. The prevalence of Jews within the non-productive sphere led to interethnic conflicts with representatives of the Ukrainian and Polish ethnoses.

    Studies on the 20th century climate change in China have revealed that under the background of global warming over the past century,climate in China has also experienced significant change with mean annual temperature increased by about 0.5 °C.More reliable results for the latter part of the 20th century indicate that the largest warming occurred in Northwest China,North China and Northeast China,and the warming in winter is most significant.Although no obvious increase or decrease trends were detected for mean precipitation over China in the past half century,regional differences are very distinct.In the middle and lower reaches of the Yangtze River,precipitation increased,while that in the Yellow River Basin markedly decreased.Studies suggest that climate change in China seems to be related not only with the internal factors such as ENSO,PDO,and the others,but also with the anthropogenic effects such as greenhouse gas emissions,and land use.The future climate change studies in China seem to be important in narrowing understanding the nature of China's climate change and its main causes,since it is significant for projection and for impact assessment of climate change in the future.

    Full Text Available The agrarian crisis in the European part of the Russian Empire in the middle of the 20th century seriously impeded agricultural progress. Agrarian overpopulation and peasants deprived of land in the course of the peasant reform of 1861 further aggravated the negative situation in the governorates of Central Russia, Belarus, and left-bank Ukraine. These factors provided fertile soil for migratory sentiments among peasants. It was resettlement in vacant lands in the Asiatic Russia and North Caucasus, which allowed most of them to preserve their homesteads. In the 2nd half of the 19th – early 20th century, Ukrainian peasants were actively engaged in the migration movement which was supported by the state. One of the main placement areas became Western Siberia where a large Ukrainian peasant community was formed. The history of research on the Ukrainian community in Western Siberia is fragmentary, as many aspects remain unstudied. Hence, the article focuses on the following questions: causes of the Ukrainian migration to the border lands of the Russian Empire; stages in the migration; main areas where Ukrainians resided in Siberia; population dynamics of the Ukrainian community; adaptation patterns specific for Ukrainian migrants in their new places of residence; their role in the economic life of Siberia in the early 20th century. This article utilizes primary data from the All-Russian Agricultural and Land Census of 1917, which have been introduced for scientific use for the first time. As the methodological basis, the study draws on the system approach combining regional, neo-imperial and comparative principles.

    Full Text Available French medicine was of the utmost importance for the birth of modern medicine and neurology in the 19 th century. Innovative approaches, such as examination at the bedside, the use of the stethoscope, techniques of auscultation, palpation, and close patient examination, besides emphasis on anatomical-clinical correlation and observation of the outcome of the disease, were put into practice. French medicine offered professional training and incentives for the beginnings of Brazilian neurology and psychiatry. Returning from France, many Brazilian physicians implemented what they had learned, mainly in Paris. The most important pupils of the French neurology schools in Brazil during the 19 th century and first half of the 20 th century include names like Antonio Austregesilo, Aloysio de Castro, Enjolras Vampré, and Deolindo Couto, founders of the leading Brazilian neurological schools, directly influenced by Dejerine, Pierre Marie, Guillain and Babinski.

    In this paper evidence of anthropogenic influence over the warming of the 20th century is presented and the debate regarding the time-series properties of global temperatures is addressed in depth. The 20th century global temperature simulations produced for the Intergovernmental Panel on Climate Change’s Fourth Assessment Report and a set of the radiative forcing series used to drive them are analyzed using modern econometric techniques. Results show that both temperatures and radiative forcing series share similar time-series properties and a common nonlinear secular movement. This long-term co-movement is characterized by the existence of time-ordered breaks in the slope of their trend functions. The evidence presented in this paper suggests that while natural forcing factors may help explain the warming of the first part of the century, anthropogenic forcing has been its main driver since the 1970’s. In terms of Article 2 of the United Nations Framework Convention on Climate Change, significant anthropogenic interference with the climate system has already occurred and the current climate models are capable of accurately simulating the response of the climate system, even if it consists in a rapid or abrupt change, to changes in external forcing factors. This paper presents a new methodological approach for conducting time-series based attribution studies. PMID:23555866

    Full Text Available About 500 tombstones from National cemetery in Martin were carried out. The cemetery represents section through sepulchral architecture in the 19th and 20th centuries and records history of natural stones use and tombstone evolution. From c. 1850, classicistic steles were produced from Gerecse marble and Banská Bystrica sandstone. Historicist steles of Silesian marble were imported from 1870s. End of 1880s years, variability of tombstone appearance began to grow. Outlined text, carved text fields, ornaments and new typefaces were emerged. In 90s years Carrara marble is imported. Real variousness of tombstone face is typical for first 20 years of the 20th century, when hard natural stones (Silesian granite, Swedish dolerite, and Norwegian larvikite are widely used. Besides them domestic Cenozoic conglomerates, Banská Bystrica sandstone and Bohemian Hořice sandstone were utilized. From 20s years to half of the century, variability of natural stones decreased at the expense of Swedish dolerite. Variety of tombstone shapes grew from decorated secession steles, through geometric functionalistic compositions, to simple tabular tombstones.

    Gardening has multiple meanings depending on where and how it is performed as well as what purpose it is attributed. This paper will discuss the meanings and cultural aspects of own-home gardens in the early 20th century Swedish urban context. Stately loans were paid out in order for people to be able to build houses with gardens, so called own-homes, in the countryside or in the outskirts of cities in the early 1900s. A home of one's own, with a garden, had a positive effect on health and so...

    Fire is the dominant natural disturbance in southeastern Australia. For millennia it has been the driving force shaping terrestrial ecosystems in the region -- simultaneously killing vegetation and initiating regeneration across whole landscapes. Fire regimes across the region are driven by several factors including climate, vegetation, and ignition sources. Humans have been a significant contributing factor to past and present fire regimes. Prior to European settlement in the late 1700s, Aboriginal Australians used frequent, low-intensity fires to manage vegetation across much of the landscape. European settlement led to the displacement of Aboriginal communities and a shift to active fire suppression and control. This changing approach to fire management is widely believed to have initiated a fundamental shift towards extreme, high-intensity fire events as fuel loads increased. In addition, during the 20th Century prolonged periods of warm, dry conditions have occurred with greater frequency and intensity. The relative importance of climate and fire management practices on contemporary fire regimes is vigorously debated in Australia and is directly relevant to land management policies and their implementation. To put the current fire regime into historical context, we used a multi-proxy approach combining palaeo-charcoal and tree-ring analyses to assess how fire regimes have changed over the last 3000 years in the Snowy Mountains region of southeastern Australia. We found almost no evidence of high-intensity fires in the 3000 years that preceded the 20th Century. However, in the mid-20th Century there is a sudden and dramatic increase in the presence of charcoal and the pulsed establishment of trees across the landscape, suggesting a recent shift from low-intensity fires with minimal charcoal signatures to moderate- to high-intensity fires with substantial charcoal inputs. Importantly, the tree-ring data demonstrate that most of these fires were not stand

    Leonor Michaelis spent the years of 1922-1926 as Professor of Biochemistry of the Aichi Medical College (now Graduate School of Medicine, Nagoya University) in Nagoya, Japan. Michaelis succeeded in gathering many bright young biochemists from all over Japan into his laboratory, and made tremendous contributions to the promotion of biochemistry in Japan. Michaelis was invited to many places in Japan to present lectures over those years. Kunio Yagi, who was Professor of Biochemistry at Nagoya University in the second half of the 20th century, succeeded in crystallizing the "Michaelis" enzyme-substrate complex. Historically, Michelis has had an enormous impact on biochemistry in Japan.

    Is it any good? Most readers have asked and been asked this question. But is there such a thing as a good book, or good writing? That is the question here, examined through a comparative analysis of the poetics of a group of 20th century writers: Jack Kerouac, David Foster Wallace, Stephen King and Ayn Rand. It appears that these writers, who had seemingly little in common except for the fact that they wrote fiction in America, mainly after World War 2, agree on some important aspects consid...

    The 20th century climate for the Southeastern United States and surrounding areas as simulated by global climate models used in the Coupled Model Intercomparison Project Phase 5 (CMIP5) was evaluated. A suite of statistics that characterize various aspects of the regional climate was calculated from both model simulations and observation-based datasets. CMIP5 global climate models were ranked by their ability to reproduce the observed climate. Differences in the performance of the models between regions of the United States (the Southeastern and Northwestern United States) warrant a regional-scale assessment of CMIP5 models.

    Held, Lisa; Rutherford, Alexandra

    2012-05-01

    Popular depictions of 20th-century American motherhood have typically emphasized the joy and fulfillment that a new mother can expect to experience on her child's arrival. But starting in the 1950s, discussions of the "baby blues" began to appear in the popular press. How did articles about the baby blues, and then postpartum depression, challenge these rosy depictions? In this article, we examine portrayals of postpartum distress in popular magazines and advice books during the second half of the 20th century to examine how the unsettling pairing of distress and motherhood was culturally negotiated in these decades. We show that these portrayals revealed a persistent reluctance to situate motherhood itself as the cause of serious emotional distress and a consistent focus on changing mothers to adapt to their role rather than changing the parameters of the role itself. Regardless of whether these messages actually helped or hindered new mothers themselves, we suggest that they reflected the rarely challenged assumption that motherhood and distress should not mix.

    Full Text Available The aim of the paper is to conduct research on the topic of ways of bookstore (sales classification of Croatian bookstores from the beginning of the 20th century. By content analysis of the 17 sales lists/catalogs of books from Dubrovnik, Split, Zadar, Karlovac, Zagreb and Osijek, the classification structure has been reconstructed, and the criteria according to which the booksellers offerings have been classified in the early 20th century have been determined. Conducting of the analysis established the following criteria of the bookstore classification: topic/content, form/type of work, type of corpus, genre, language, purpose, publishing series, publisher, time of publication, (new edition, time of publication/purchase, customer's specific interests, number, letter and author. Order of enumeration within specific categories is mostly alphabetic, numeric or according to order of publication. Unlike the library classification and classification systems in general, the problematics of bookstore classification is not very present in the current existing sources. Research studies that focus on the history of bookselling, even if they reveal ways of classification of booksellers offers remain on a descriptive level without any deeper analysis of the criteria or possible reasons of such classification. Therefore, the contribution of the paper is a detailed analysis of a larger pattern of bookstore sales catalogs, and also an attempt of illuminating the criteria and reasons of creating a system of bookstore classification in the defined historical, spatial and time context.

    Extra-tropical cyclones and wind storms are responsible for a large portion of damages all around the globe. Thus, knowledge about the temporal variability of these events during the past is of high socio-economic importance. In this study, the temporal variability of extra-tropical cyclones and wind storms during the past century are analysed using ERA-20C and NOAA-20CR reanalysis datasets. Cyclones are identified using six hourly mean sea level pressure fields whereas wind storms are identified based on near-surface wind speeds. Analyses focus on wintertime events over both hemispheres and also for several subregions. Long-term trends as well as higher-frequency variability are investigated. Therefore, cyclone and wind storm time series are low-pass filtered with a cut-off frequency of 1/31 years using 31 weights and the high-frequency time series are obtained by calculating the residuum of the original and low pass-filtered time series. To analyse long-term trends, a linear regression model is fitted to the original time series for three different periods: 1901-1930, 1931-1960 and 1961-1999. Results suggest substantial differences regarding long-term trends between ERA-20C and NOAA-20CR for cyclones and wind storm events, especially during the first half of the 20th century. In general, a better agreement is found for extreme cyclones compared to all cyclones. Furthermore, high-frequency variability over the Northern Hemisphere is in good agreement for cyclones and wind storms over most regions and throughout the century, with the highest correlations found at the end of the 20th century. Analyses for the Southern Hemisphere show smaller agreement between ERA-20C and NOAA-20CR for cyclone and wind storms regarding their high-frequency variability. The results of this study indicate that no reliable conclusion regarding long-term variability of cyclones and wind storms can be drawn, based on solely these two 20th century reanalysis products. However, analyses

    Full Text Available A 137 m ice core drilled in 1999 from Eastern Bolivian Andes at the summit of Nevado Illimani (16º 37' S, 67º 46' W, 6350 m asl was analyzed at high temporal resolution, allowing a characterization of trace elements in Andean aerosol trapped in the ice during the 20th century. The upper 50 m of the ice core were dated by multi-proxy analysis of stable isotopes (d18O and d2H, 137Cs and Ca+2 content, electrical conductivity, and insoluble microparticle content, together with reference historical horizons from atmospheric nuclear tests and known volcanic eruptions. This 50 m section corresponds to a record of environmental variations spanning about 80 years from 1919 to 1999. It was cut in 744 sub-samples under laminar flow in a clean bench, which were analyzed by Ion Chromatography for major ionic concentration, by a particle counter for insoluble aerosol content, and by Inductively Coupled Plasma Mass Spectrometry (ICP-MS for the concentration of 45 chemical species from Li to U. This paper focuses on results of trace element concentrations measured by ICP-MS. The high temporal resolution used in the analyses allowed classifying samples as belonging to dry or wet seasons. During wet season elemental concentrations are low and samples show high crustal enrichment factors. During dry seasons the situation is opposite, with high elemental concentrations and low crustal enrichments. For example, with salt lakes as main sources in the region, average Li concentration during the 20th century is 0.035 and 0.90 ng g-1 for wet and dry seasons, respectively. Illimani average seasonal concentration ranges cover the spectrum of elemental concentration measurements at another Andean ice core site (Sajama for most soil-related elements. Regional crustal dust load in the deposits was found to be overwhelming during dry season, obfuscating the contribution of biomass burning material.

    Full Text Available The poetry of César Simón is still maintaining the ungrateful marginal position. Although many eminent poets and critics recognize the Simón's opus as one of the most comprehensive and pervasive in the second half of the 20th century, it still has not entered into literary and critical studies. The persistent silence that hovers over Simón's work is a result of the difficulty of its clasification and of the peculiarities of its aesthetic principles in the context of Spanish poetry of the last century. This article attempts to bring closer Simón's work and thus contribute to the proliferation of views on this different poetics.

    Full Text Available 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 20(th 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 20(th 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 16(th century, but did not become commercially significant until the 19(th century. From then until now herring have been the dominant catch.

    The past century changed the classical, scientific way of view enormously. The quantum theory broke with the imagination of continuity of all dynamical processes and gave space to completely new, nearly revolutionary approaches of thinking. Einstein's relativity theory put the absoluteness of time and space as well as the general validity of the Euclidean geometry in question. The absolute calculability, as it was formulated by Laplace, was by the influence of chaos theory proven as illusion. Computers made by the Mandelbrot set the presentation of new esthetic and never seen structures. Hilbert's century program of a complete formalization of mathematics failed because of the famous law of Goedel. It is the demand of this book to present all these theories and conclusions easily understandably and entertainingly.

    Full Text Available The article analyses the political views of Canadian intellectuals which had influence on the formation of Canadian political culture at the turn of the 20th century. The author confirms that the Canadian intellectual thought was the main ideological factor in the conditions of the formation of Canadian statehood, undeveloped party and political system, the lack of deep traditions of the parliamentary system, insufficient political practice and the lack of distinct ideology of basic political parties in the process of forming the Canadian nation. On the basis of studied Canadian sources, the author makes conclusion that the most of Canadian intellectuals did not participate directly in the political process and they considered themselves its bystanders. Besides, the Canadian intellectuals promoted the British political culture of the Victorian epoch. Although all of them were familiar wih the British socialistic thought – Fabianism, they insisted that the social transformation in the Canadian society is possible only through the improvement of moral system, the education of lower social classes and the maintenance of elite monarch traditions. The American influence on Canadian political culture was peripheral at the beginning of the 20th century. The ideas of the Chicago Sociological School and the European continental thought were not used. The Victorian intellectuals understood their time as the social crisis and their political discussions were often devoted to the problems of imperialism, religion, education and feminism. They undoubtedly influenced the Canadian political elite in the matter of further development of the Canadian nation and state, but they expressed their own unique views on the contemporary society in academic press and in elite clubs discussions. They did not share the opinion of publicity about contemporary social processes, because their position was far from the direct party policy. Though some of them participated as

    Full Text Available The paper tackles the controversial question of the affinities between the work of Aby Warburg and Carl Gustav Jung. Instead of focussing her interest exclusively on the concepts of collective memory and primordial images, though, the author critically compares the different ways Warburg and Jung looked at the renaissance of ancient practices of Paganism at the beginning of the Twentieth century, and questions the extent to which the cultural crisis heralded by Modernity, and the challenges brought about by secularisation influenced their reading of the revivals.

    Full Text Available War, in its various forms, still represents even in the XXI century a common manner for states as well as for ethnic, political and religious groups to settle disputes. The geopolitical context, marked by the al Qaeda attacks on the USA, and the multiple world events they determined lead to major changes for the armed violence character and simultaneously for its moral implications. Therefore, the present analysis subjects the relevance of the just war theory for the new international realities, the degree to which the theory needs a revision of its classical categories ius ad bellum and ius in bello or, on the contrary, an abandonment.

  15. The Welfare Culture. Poetics of Comfort in Architecture of the 19th and 20th-centuries

    Eduardo Prieto González

    2013-10-01

    Full Text Available AbstractArchitectural history of the last two centuries shows that welfare, far from being a purely technical issue – a balance between weather and the physiological human constants – is a culturally constructed idea concerning diverse factors, such as the relationship between space and human body or the ways of conceiving nature in architecture. However, the notion of comfort has not received the historiographical attention it deserves, hence the need for a new perspective, aesthetic and multidisciplinary in nature. Such a view is discussed in this article through a brief and partial history of comfort that addresses the different meanings assigned to the concept over the past two centuries, in accordance with a kind of 'poetics': the longstanding poetics of fire, linked the regenerative comfort; the poetics of hygiene and habitat, developed during modernity as a scientifistic dogma and as an aesthetic alibi, and, finally, the poetics of atmospheres, which accounts for contemporary concerns about perception, memory and sociability. From this historical review we can conclude that welfare is not an objectifiable concept, nor an idea synthesized in the technician or scientist test tubes, but a complex notion consisting of several intertwined layers: physiological, constructive, aesthetic, existential, social. The history of comfort is, thus, a sort of small version of the history of culture.Key wordscomfort, architecture, hygiene, habitat, atmosphere

    Full Text Available The article is devoted to studying the reasons and preconditions for religions, educational and missionary activities of the Russian Orthodox Church in the late 19th – early 20th centuries. Basing on the archive records, the author shows that most important preconditions for enhancing religions – educational activities were the following: the destruction of traditional patriarchal life of the masses, which was based on religions values, the need to overcome “religions ignorance” of a significant part of Orthodox population, the rapid religions dissent in the Russian Empire. Analysis of reasons for their wide spread shows that it wasn’t the cause of foreign influence or any kind of social protest. Studying contemporary opinions as well as specific facts of provincial parish life led to the conclusion that there existed a wide complex of preconditions that influenced the growth of “protest” forms of religion.

    Tibetan archaeology has always drawn close attention from academic circles both athome and abroad. In the first half of the 20th century, archaeological work in this region was principallydone by Western scholars. They obtained some achievements, such as those in the surveys of Tubo royaltombs, though there appeared shortcomings. Since the 1950s, Chinese scholars have independently car-tied out a series of archaeological surveys and diggings on the Qamdo karub site and in the NaogxianLieshan cemetery. The 1990s was an remarkable decade, when Tibetan archaeology was going ahead byleaps and bounds. The general investigation of ancient monuments across Tibet laid the foundations offuture Tibetan archaeology. The excavation of the prehistoric site at Qugoog village, Lhasa, the explo-ration of the ancient Guge city in Ngari and other archaeological projects carried out in recent years ex-erted significant influence in Chinese and foreign academic circles.

    Full Text Available This essay deals with the Slovene reaction to the military intervention of eight coalition forces in China during the Boxer Rebellion in China in 1900. To Slovenes, China was then seen as a faraway land that had been visited by some Slovene missionaries, noblemen and travellers throughout the past centuries. Nevertheless, much interest was expressed by the Slovene public and press in the events surrounding the Boxer Rebellion. Despite the fact that the Austro-Hungarian military was part of the international coalition that intervened in Chinese internal affairs, the leading Slovene newspapers of the period supported the right of the Chinese people to defend their country against the big powers of the time, who tried to dismember China and enforce the regime of capitulation.

    Full Text Available Tropical rainforest dwellers, who are currently engaged in bushmeat trade, used to track game for their own subsistence. We investigate the technical evolution over the past century of bushmeat procurement by the Fang, a group of southern Cameroon forest dwellers who are renowned for their extensive cynegetic expertise. This investigation consists of a diachronic approach to assess Fang hunting and trapping technology by comparing firsthand data on bushmeat procurement collected in the early 1990s with detailed descriptions recorded in the early 1900s among the same populations by the German anthropologist Günter Tessmann. Other archive sources bequeathed by explorers in the twilight of the 19th century are also exploited. The comparison conveys a more dynamic view of hunting practices following the greater involvement of the Fang hunters in the bushmeat trade. Historical sources remind us that projectile weapons were initially destined for warfare and that trapping, mobilizing a vast panel of modalities, was the prominent means to catch game for domestic consumption. Net hunting and crossbow hunting, which used to be typical Fang activities, are now exclusively conducted by Pygmies; spear hunting with hounds has become anecdotal. If a large range of trap mechanisms is still functional, effort is now focused on snares, elicited by the banalization of twisted wire cable. The legacy of other remaining models is left to children who carry out a didactic form of garden trapping. The major detrimental change is the use of firearms, which were initially adopted as a warfare prestige attribute before becoming the backbone instrument of bushmeat depletion. Revisiting the past provides useful lessons for improving current hunting management, through the promotion of garden hunting and wildlife farming, and the revitalization of a collective and cultural art of hunting as an alternative to indiscriminate overhunting by neophyte and increasingly

  20. The role of deep processes in late 20th century subsidence of New Orleans and coastal areas of southern Louisiana and Mississippi

    Geodetic leveling observations from Biloxi, MS, to New Orleans, LA, and water level gauge measurements in the New Orleans-Lake Pontchartrain area were analyzed to infer late 20th century vertical motions. These data were used to test the validity of previous subsidence rate measurements and the models that predict the location and causes of subsidence. Water gauges attached to bridge foundations and benchmarks affixed to deep rods that penetrate Holocene strata subsided as much as 0.8 m locally between 1955 and 1995. The observed deep-seated subsidence far exceeds model predictions and demonstrates that shallow processes such as compaction and consolidation of Holocene sediments are inadequate by themselves to explain late 20th century subsidence. Deep-seated subsidence occurring east and north of the normal faults marking the Gulf of Mexico basin margin can be explained by local groundwater withdrawal, and regional tectonic loading of the lithosphere by the modern Mississippi River delta (MRD). Sharp changes in subsidence coincide with strands of the basin margin normal faults. Displacements are consistent with activity and show motions consonant with fault creep. Deep subsidence of the region to the south, including New Orleans, can be explained by a combination of groundwater withdrawal from shallow upper Pleistocene aquifers, the aforementioned lithospheric loading, and perhaps, nongroundwater-related faulting. Subsidence due to groundwater extraction from aquifers ˜160 to 200 m deep dominated urbanized areas and is likely responsible for helping to lower local flood protection structures and bridges by as much as ˜0.8 m.

    Full Text Available Laguna Mar Chiquita is a highly variable closed saline lake located in the Pampean Plains of central Argentina. Presently is the largest saline lake in South America (∼ 6,000 km2 and also one of the largest in the world. During the 20th century the hydrological balance of the region was characterized by contrasting scenarios. Well-defined wet or dry climatic phases had ruled the lake level fluctuations and the rivers discharge, mainly controlling the geochemical composition of sediments. Sediments accumulated during positive hydrological balances (i.e., high lake level are mainly composed of allogenic mineral due to higher riverine inputs into the lake. This fluvial-dominated lake phases are recorded as sediments enriched in Al2O3, SiO2, K2O, Fe2O3 and TiO2 and in trace elements such as Co, Cr, Cs, Rb, Sc, Hf, Ta, Th as well as rare earth elements (REE. Sediments accumulated during dry phases (i.e., low lake levels and high salinity are evaporite mineral-rich with elevated concentrations of CaO, MnO, MgO, and P2O5. High contents of As and U are probably due to a co-precitation during high evaporative phases. The calibration of the sediment chemical composition of Laguna Mar Chiquita to well-defined water-level fluctuations of the 20th century shows that elemental geochemistry can be a useful proxy to study former lake-water fluctuations. It may further provide a comparative model to evaluate past environmental conditions in other saline lacustrine basins.

  2. Underground fieldwork – A cultural and social history of cave cartography and surveying instruments in the 19th and at the beginning of the 20th century

    2015-09-01

    Full Text Available At the turn of the 20th century, the practical examination of caves went through a radical change. Governmental organizations and private clubs were founded in an attempt to establish speleology as an independent academic subject. In contrast to earlier cave visitors, travelers began entering underground areas and attributing the names of “explorers” or “researchers” to themselves. Fieldwork—especially cave surveying and cartography—became common practice in speleology and such work provided important clues on speleogenesis, which was a controversial issue in the first half of the 20th century. Due to the fact that speleologists began separating themselves from ordinary cave visitors and tourists, tools and instruments for cave exploration and mapping, such as carbide lamps, ropes, compasses, clinometers, and drawing boards, became the emblems of speleology. Through historical discourse analysis, this paper examines whether this change in the status and practice of underground fieldwork had an effect on the self-perception of speleology and led to new forms of social cooperation and control between speleologists. Further questions address the manner in which the usage of new surveying instruments and the relevance of cave mapping modified the scientific research parameters and the cultural perceptions of the subterranean world. As a contribution to speleo-history, this approach opens a new perspective on the social and cultural dimensions of speleological fieldwork as well as the historical, scientific, and political dynamics in which they were involved. Sources for this research comprised historical scientific papers on cave mapping, textbooks, and archive materials from the Austrian National Library, the Natural History Museum in Vienna, and the Austrian Speleological Association.

  3. Changes in the relationships between climate and silver fir (Abies alba Mill.) growth during the 20th century in the Tuscan Apennine Alps (Middle Italy)

    In the Tuscan Apennine Alps, recent research has shown that similarity in trends of monthly climate variables (i.e., temperature and rainfall) is non-stationary amongst sites during the 20th century even between sites that differ little in elevation and at a relatively short distance from each other (D'Aprile et al., 2010; D'Aprile et al., 2011). Moreover, the level of correlation between series of monthly climate variables varies irregularly from highly positive to negative over time. We hypothesised that those changing climate conditions, even at the local level, could cause different tree-ring growth responses in silver fir amongst sites. The hypothesis was tested by dendroclimatological analysis, which was applied to study stands in silver fir forests close to the meteorological stations where climate analysis has been made. Results show that the influences of both monthly mean temperature and monthly rainfall on silver fir growth vary greatly during the 20th century in the Tuscan Apennine Alps, and the ways that they change differ with month and amongst sites. Within sites, differences in the relationships between climate variables and silver fir tree-ring growth appear small in spite of different elevation of the study stands. These results contribute a changing point in forest planning and management especially in consideration of the need to adapt forest management and interventions to changing climate conditions and mitigate the impacts on silver fir forests. Moreover, they introduce climate variability as a key parameter in sustainable forest management for biodiversity conservation, socially responsible uses, nature conservation, and survival of the only conifer tree species typical of mountain mixed forest ecosystems in the Apennine Alps.

    Simulations of aerosols, clouds and their interaction contribute to the major source of uncertainty in predicting the changing Earth's energy and in estimating future climate. Anthropogenic contribution of aerosols affects the properties of clouds through aerosol indirect effects. Three different versions of NASA GISS global climate model are presented for simulation of the twentieth century climate change. All versions have fully interactive tracers of aerosols and chemistry in both the troposphere and stratosphere. All chemical species are simulated prognostically consistent with atmospheric physics in the model and the emissions of short-lived precursors [Shindell et al., 2006]. One version does not include the aerosol indirect effect on clouds. The other two versions include a parameterization of the interactive first indirect aerosol effect on clouds following Menon et al. [2010]. One of these two models has the Multiconfiguration Aerosol Tracker of Mixing state (MATRIX) that permits detailed treatment of aerosol mixing state, size, and aerosol-cloud activation. The main purpose of this study is evaluation of aerosol-clouds interactions and feedbacks, as well as cloud and aerosol radiative forcings, for the twentieth century climate under different assumptions and parameterizations for aerosol, clouds and their interactions in the climate models. The change of global surface air temperature based on linear trend ranges from +0.8°C to +1.2°C between 1850 and 2012. Water cloud optical thickness increases with increasing temperature in all versions with the largest increase in models with interactive indirect effect of aerosols on clouds, which leads to the total (shortwave and longwave) cloud radiative cooling trend at the top of the atmosphere.

    Full Text Available Demographic development belongs to the group of the primary social and developmental issues, and the demographic processes and tendencies in the population trends are included in the basic social processes which are expressed by the demographic (that is, synthetic social indicators. The process of the depopulation of Vojvodina is a result of the several-decades long decrease in birthrate, ageing of the population and mortality rate which is related to a series of historical, socioeconomic, cultural educational, specifically local, family, as well as psychological factors. Unfavourable demographic circumstances in Vojvodina started already in the 1920s, and became more pronounced after World War II, in 1989 resulting in the negative natural increase (-1%o, in the process of a more intensive decrease in the population which today, in the 21st century, acquires greater dimensions (-4,7%o in 2002, creating not only disturbances in the demographic, but also in the economic-social structures. Taking into account the far-developed process of demographic ageing of the population of Vojvodina and the accepted reproductive norms implying a low fertility (giving birth to a smaller number of children or only one child which does not ensure even the simple reproduction of the population, one cannot expect - in spite of the present immigrational processes (the inflow of refugees and the absolute increase in the population (between the previous two censuses - significantly more favourable population trends and a better prospective demographic picture of Vojvodina.

    2011-03-01

    Full Text Available A heat flow model was used to simulate both past and future ground temperatures of mountain permafrost in Southern Norway. A reconstructed air temperature series back to 1860 was used to evaluate the permafrost evolution since the end of the Little Ice Age in the region. The impact of a changing climate on discontinuous mountain permafrost until 2100 is predicted by using downscaled temperatures from an ensemble of downscaled climate models for the A1B scenario. From 13 borehole locations two consecutive years of ground temperature, air temperature and snow cover data are available for model calibration and validation. The boreholes are located at different elevations and in substrates having different thermal properties. With an increase of air temperature of ~+1.5 °C over 1860–2010 and an additional warming of +2.8 °C towards 2100 in air temperature, we simulate the evolution of ground temperatures for the borehole locations. According to model results, the active-layer thickness has increased since 1860 by about 0.5–5 m and >10 m for the sites Juvvass and Tron, respectively. The simulations also suggest that at an elevation of about 1900 m a.s.l. permafrost will degrade until the end of this century with a likelihood of 55–75% given the chosen A1B scenario.

    Full Text Available The teaching of evolution in the Portuguese secondary schools is not yet fully understood. This research aimed to contribute to this clarification, in the framework of the history of the curriculum and the biology subject, by showing the expressions of the evolutionism teaching in the first three decades of the twentieth century. To this end we analyzed the programs of Zoology of 1905 and 1919, as well as two textbooks, entitled «Lições de Zoologia» and written by Bernardo Aires in accordance with these programs. This analysis showed that the study of evolution, eliminated from the program in 1905, was again recognized in the program in 1919. In textbooks, the exposure of evolution focused on the subject of evolution, in the grounds of competition and natural selection, adaptation, the biogenetic law and the essential differences between Lamarckism and Darwinism. The comparative study of these textbooks showed that the text which addresses the evolution is essentially Darwinian. However, neoLamarckians sections have been identified that show the influence of the «eclipse of Darwinism» on the teaching of evolutionism.

    2016-04-01

    Full Text Available The present article is based on Western, Japanese and field-work materials of the author who describes the main stages of formation of the Indian entrepreneurial diaspora in Japan in the period from the late 19th century until the beginning of the World War II. Indian entrepreneurs, being the representatives of trade and usury communities, Sindhis and Parsis in particular, started to arrive here in 1870s under British protection. Their main occupation was the export of Japanese textile which was the main export item of Japan in the mentioned period. Indians maintained the export of the textile goods, silk and cotton, in different countries all over the world through their strong entrepreneurial networks. The majority of Indian firms in Japan were Sindhis firms, and Sindhis network was especially prominent. Indian firms especially prospered in 1920-1930s, when their share of Japanese textile export constituted about 70 %. Thanks to strong ethnic loyalties, Indians in Japan could not only prosper but also successfully adapt to closed Japanese society. The article considers the pattern of settlement of Indians in Japan, and emphasizes two stages of Indian community formation in the pre-War period. The first one lasted from 1870s till 1923 year, when the community was formed basically in Yokohama. And the second stage after Great Kanto Earthquake lasted from 1923 till 1939, when it was constituted mainly in Kobe, which in present days remains the centre of Indian entrepreneurial community in Japan.

    Thanks to their ability to synthesize a wide variety of meteorological data and "produce data where there are none", nowhere are global atmospheric reanalyses more needed than over Antarctica and the Southern Ocean, where long-term records are few and far between. At the same time, because of the reduced observational constraint, nowhere else do reanalyses face more challenges, which can significantly reduce the reliability of their products. Most notably, the transition into the modern satellite era in 1979 greatly affected the skill of the NCEP-NCAR and ERA-40 reanalyses and explains why most reanalysis-based investigations of Antarctic climate change have since focused on the post-1979 period. The most recent generation of reanalyses has benefited from advances in numerical weather prediction, data rescue/quality-control and lessons learned from previous projects, all of which have improved their overall quality in the southern polar region. Alongside comprehensive reanalyses, recent data assimilation experiments using only surface or conventional observations have tried to overcome the 1979 "barrier", but other problems have become apparent, including the necessity to specify realistic ocean boundary conditions (sea ice, SST) around Antarctica prior to 1979. The presentation will provide an overview of the skill of recent global reanalyses in high southern latitudes from the 1900s onward. It will discuss how far back in time we can reasonably go and in what areas caution is needed. The datasets covered will include ERA-Interim, CFSR, MERRA, and JRA-55, as well as recent century-long efforts, 20CR and ERA-20C.

    The boreal summer Asian monsoon has been evaluated in 25 Coupled Model Intercomparison Project-5 (CMIP5) and 22 CMIP3 GCM simulations of the late twentieth Century. Diagnostics and skill metrics have been calculated to assess the time-mean, climatological annual cycle, interannual variability, and intraseasonal variability. Progress has been made in modeling these aspects of the monsoon, though there is no single model that best represents all of these aspects of the monsoon. The CMIP5 multi-model mean (MMM) is more skillful than the CMIP3 MMM for all diagnostics in terms of the skill of simulating pattern correlations with respect to observations. Additionally, for rainfall/convection the MMM outperforms the individual models for the time mean, the interannual variability of the East Asian monsoon, and intraseasonal variability. The pattern correlation of the time (pentad) of monsoon peak and withdrawal is better simulated than that of monsoon onset. The onset of the monsoon over India is typically too late in the models. The extension of the monsoon over eastern China, Korea, and Japan is underestimated, while it is overestimated over the subtropical western/central Pacific Ocean. The anti-correlation between anomalies of all-India rainfall and Niño3.4 sea surface temperature is overly strong in CMIP3 and typically too weak in CMIP5. For both the ENSO-monsoon teleconnection and the East Asian zonal wind-rainfall teleconnection, the MMM interannual rainfall anomalies are weak compared to observations. Though simulation of intraseasonal variability remains problematic, several models show improved skill at representing the northward propagation of convection and the development of the tilted band of convection that extends from India to the equatorial west Pacific. The MMM also well represents the space-time evolution of intraseasonal outgoing longwave radiation anomalies. Caution is necessary when using GPCP and CMAP rainfall to validate (1) the time

    Full Text Available Glaciers respond to mass balance changes by adjusting their surface elevation and area. These properties in their turn affect the local and area-averaged mass balance. To incorporate this interdependence in the response of glaciers to climate change, models should include an interactive scheme coupling mass balance and ice dynamics. In this study, a spatially distributed mass balance model, comprising surface energy balance calculations, was coupled to a vertically integrated ice-flow model based on the shallow ice approximation. The coupled model was applied to the ice cap Hardangerjøkulen in southern Norway. The available glacio-meteorological records, mass balance and glacier length change measurements were utilized for model calibration and validation. Forced with meteorological data from nearby synoptic weather stations, the coupled model realistically simulated the observed mass balance and glacier length changes during the 20th century. The mean climate for the period 1961–1990, computed from local meteorological data, was used as a basis to prescribe climate projections for the 21st century at Hardangerjøkulen. For a linear temperature increase of 3 °C from 1961–1990 to 2071–2100, the modelled net mass balance soon becomes negative at all altitudes and Hardangerjøkulen disappears around the year 2100. The projected changes in the other meteorological variables could at most partly compensate for the effect of the projected warming.

  13. 20th Century variability of Atlantic Meridional overturning circulation: Planetary wave influences on world ocean surface phosphate utilization and synchrony of small pelagic fisheries

    Kamykowski, Daniel

    The Atlantic Meridional Overturning Circulation (AMOC), part of the global Thermohaline Circulation (THC), is variable. In the present analysis, an Atlantic Dipole Phosphate Utilization (ADPU) index, related to the existing Atlantic Dipole Sea Surface Temperature Anomaly (ADSA) index, is used to represent 20th century changes in AMOC strength that are applied to global ecosystem variability. ADPU index cycles set the timing for the calculation of six 2° latitude-longitude resolution world ocean maps depicting higher surface phosphate utilization (SPU) in some regions when AMOC is weaker and in other regions when AMOC is stronger. The average of these six maps yields a summary map with a pattern of alternating latitudinal SPU regions differentiated by AMOC strength that exhibits relationships with ocean bathymetry and wind-driven currents through a consideration of the THC deep and shallow limbs. The latitudinal pattern of SPU regions exhibits conceptual associations with sardine (S) and anchovy (A) population ranges off Japan (J), California (C), Peru (P) and South Africa (B). These sardine and anchovy populations have exhibited apparently synchronous fluctuations on decadal scales through at least part of the 20th century that is summarized in a Regime Indicator Series (RIS=(JS+CS+PS+BA)-(JA+CA+PA+BS)) index. In the present analysis based on Food & Agriculture Organization (FAO) catch data, a revised Regime Indicator Series index formulation (RIS3=(JS+CA+PS+BA)-(JA+CS+PA+BS)), in which CS and CA catches reverse positions, is defined. AMOC variability represented in ADPU is significantly correlated with the RIS3 index (no lag but a significant range of 14 years) and four of eight small pelagic fisheries (JS, PS, BA, and JA). The post-1950 RIS3 index is significantly correlated with seven of eight small pelagic fisheries but not CS. When the regional small pelagic fisheries are considered as normalized species differences (S-A), ADPU has significant positive

    In this paper, it was studied how physics affected development of optometry in the United States, from aspects of formation and academization of optometry. It was also revealed that history of optometry was analogous to history of engineering. Optics in the 19th century was divided into electromagnetic study of light and visual optics. Development of the visual optics promoted professionalization of ophthalmology that had already started in the 18th century. The visual optics also stimulated formation of optometry and optometrists body in the late 19th century of the United States. The American optometrists body were originated from opticians who had studied visual optics. Publication of several English academic textbooks on visual optics induced appearance of educated opticians (and jewelers). They acquired a right to do the eye examination in the early 20th century after C. F. Prentice's trial in 1897, evolving into optometrists. The opticians could be considered as craftsmen, and they were divided into (dispensing) opticians and optometrists. Such history of American optometrists body is analogous to that of engineers body in the viewpoints of craftsmen origin and separation from craftsmen. Engineers were also originated from educated craftsmen, but were separated from craftsmen when engineering was built up. Education system and academization of optometry was strongly influenced by physics, too. When college education of optometry started at American universities, it was not belonged to medical school but to physics department. Physics and optics were of great importance in curriculum, and early faculty members were mostly physicists. Optometry was academized in the 1920s by the college education, standardization of curriculum, and formation of the American Academy of Optometry. This is also analogous to history of engineering, which was academized by natural sciences, especially by mathematics and physics. The reason why optometry was academized not by

In 20th century Chinese literature Gun Yu prototype is not simply repeat the Gun Yu myth, not just confined to a single, forever hero model, but with the development of history and the cultural background of the different age is rich, the constantly changing, constantly displacement deformation, from hero to ordinary mortals. In 20th century Chinese literature Gun Yu prototype become forces so as to express its own cultural codes, not only reflects the profound connotation of culture and history of the works, but also let us in the same original thinking mode of the experience of different cultures, and more direct, more profound understanding prototype this is both abstract and concrete, is both varied and genetic stability of human culture and literature.%鲧禹神话作为原型在文学中被塑造成英雄神话,它凝结了人类对英雄的崇拜,积淀在原始先民的意识底层。20世纪中国文学中的鲧禹原型并不是对鲧禹神话的简单重复,也不仅局限在单一的、永远不变的英雄模式,而是随着历史发展和不同时代文化背景被不断丰富、变化,不断置换变形,从英雄走向普通凡人。20世纪中国文学中的鲧禹原型成为各种力量借以表达自身的文化符码,既体现出了作品的深厚的文化底蕴和历史内涵,又能让我们在相同的原始思维的模式下体验不同的文化,也能更直接、更深刻地认识原型这一既抽象又具体,既多变又稳定的人类文化与文学基因。

    The purpose of this paper is to use climatic history for contributing to the general objectives of the IAI -CRN II-047 Project. It will reconstruct, from archival documents, the hydroclimatic variability occurring in the high basin of the Bermejo River during the last centuries and its effects on the floods and swellings in the middle basin. The Río Bermejo in the Southern Andes, is a binational (Argentina-Bolivia) river that contributes the largest proportion of the sediment load to the La Plata basin. Its headwaters are in the Subtropical Andes, near Tarija, Bolivia (22?00'14"S, 64?57'38"W). The main headwater tributaries are the Río Grande de Tarija, in Bolivia and the Iruya and San Francisco Rivers in Argentina. When the river abandons the mountain and turns eastwards (Gran Chaco), it acquires the characteristics of typical lowland rivers, widens its course, and occupies a large, low sedimentary plain with vast floodland areas. Quite often during very high sediment discharge the main river avulses and changes its course, creating big alluvial plains that are occupied for many years. Administrative documents from the colonial and republican periods have provided useful information to reconstruct climate and hydrology of the region. Documents from the Archivo General de Indias in Seville, Archivo Nacional de Bolivia and Archivo General de la Nación (Argentina) have been used to identify extreme floods and swellings in the high and middle-basin of the Rio Bermejo from the 17th century to the first decades of the 20th century. Old maps of the region, reports from annals, chronicles, priests' and travelers' descriptions were also used. Diaries written by the military, explorers and government officials in charge of discovering and taking possession of the territory also provide important sources of information. The archival documents show abrupt hydrological changes in response to the climatic fluctuations in the headwaters region. These records document

  18. FIRST STEPS IN URBAN PLANNING OF BULGARIAN CITIES WITH PARTICIPATION OF CZECH ARCHITECTS AND ENGINEERS AT THE TURN OF 19TH AND 20TH CENTURIES

    Full Text Available This article focuses on beginnings of the urban planning and first organized planning activities of Bulgarian cities at the turn of 19th and 20th centuries when many Czech engineers and architects participated in significantly. A common feature of all Bulgarian cities was irregular structure and build-up area. The main task of the Czech engineers was to cope with this situation and to design modern cities. In general, the original structure did not make planning easy and unambiguous. Planning of the cities destroyed in the Russian-Turkish war in 1877-78 was easier. A possibility to apply a new city structure freely existed in Stara Zagora and partially in Nova Zagora. A usual principle was straightening of the streets where the engineers used original street network and the new modern streets were built according to it, e.g. the centre of Kystendil and the old part of Nova Zagora. These principles were used also in some central parts of Sofia and Plovdiv. The city of Sofia itself is a distinctive example. Although the original structure was preserved during the war and in the first steps the principle of straightening of the streets in the centre was applied, the other parts of Sofia were designed with a new structure and the old city disappeared. Plovdiv is in contrary to Sofia and its original structure was preserved as an old city and the new one was joined to it in neighbourhoods.

    On insanity, life crises and the longing for a "right life". A contribution to the discussion on the deviant behavior and mental disorders in the psychiatry of the 19th and 20th centuries using the example of patient stories. History of psychiatry, understood as social and cultural history, provides the framework for this micro-historical article. Using the example of three patients treated in Wuerttemberg or Baden psychiatric asylums between 1875 and 1912, the article focuses on the critical analysis of types of asylums, their practices of admissions, therapies and power relations between patients and staff. Ways of thinking and acting, subjective experiences and emotions are exemplified by patient records, personal testimonials and contemporary publications again by patients and staff. The article examines options of patients to influence the institutional daily asylum routine against the background of its complexity and dynamics. Borders, manipulations, malingering and querulous paranoia are at stake here. Furthermore, the article reflects various forms of social interaction with the power regulating therapeutic and disciplinary aspects against the backdrop of the "canons of rules" of the asylum as well as the contemporary political and legal framework.

    Full Text Available In this article the hazy boundary between folklore and literature, orality and literacy is explored in relation to the individual and the community. How do people who belong to the first generation of active writers in their family and community express their own experiences through fictional narratives and the literary tradition? This question is explored in relation to the working-class youth in the small industrial community of Karkkila (Högforsin southern Finland. The most important research materials are the editions of hand-written newspapers written by these young people from 1914 to 1925.My theoretical background is derived from both folklore studies and book history. Inspired by the research of Robert Darnton, I have outlined the communication circuit of the working-class youth during the early 20th century, discussing the position of the manuscript tradition (hand-written newspapers, ballad books, minutes in relation to the printed texts(books, newspapers, broadsheets and the oral tradition. In my article I focus on the narratives of love in the manuscripts written by the working-class youth. How do they work with the ideas and narrative genres and themes adopted from the printed media and the oral tradition? I outline fictionalization of personal experiences and localization of fictional, printed texts as two basic narrative strategies utilized in these processes.

  1. Risk communication and the transformations in the meta narrative of the nuclear field in the 20th and 21st centuries

    International Nuclear Information System (INIS)

    The meta narrative of the nuclear field was influenced in the beginning by the perspectives of economic prosperity and the possibility of diversifying to alternative sources of power. However, it has been transformed throughout the 20th and the early 21st centuries by the collective memory and micro narratives of the nuclear bombs during the II World War and the nuclear or radiologic incidents of Three Mile Island, in 1979, Chernobyl, 1986, Goiania, 1987, and Fukushima, 2011. The most recent occurrence made countries like France and Germany, which depend a great deal on nuclear power supply, to suspend their nuclear programs, although having to retake them afterwards due to the impossibility of getting new sources of energy in a short period of time. All that attracted negative attention to the field and severely impacted the perception of risk by the society. This paper observes the future of the meta narrative in such area will be based in the influence of other national and supranational risk communication narratives around security, pollution, environment and economy. The discussion is based on theories by researchers such as Andreas Huyssen, Carlo Ginzburg, Lorenzo Negri, Maurice Halbwachs, Max Weber, Pedro Fernando Bendassolli, Peter Sandman, Roland Barthes, Ulrick Beck and Walter Benjamin.

  4. The speech choir in central European theatres and literary-musical works in the first third of the 20th century

    2015-01-01

    Full Text Available Speech choirs emerged as an offshoot of the choral gatherings of a wider youth musical and singing movement in the first half of the 20th century. The occasionally expressed opinion that choral speaking was cultivated primarily by the Hitler Youth and pressed into service on behalf of Nazi nationalist and racist propaganda is, historically, only partially accurate. The primary forces of choral speaking in Germany were, from 1919, the Social Democratic workers’ and cultural movement and the Catholic youth groups, in addition to elementary and secondary schools. The popularity of speech choirs around 1930 was also echoed in the music of the time. Compositions for musical speech choirs were produced by composers like Heinz Thiessen, Arnold Schönberg, Ernst Toch, Carl Orff, Vladimir Vogel, Luigi Nono, Helmut Lachenmann and Wolfgang Rihm. Moving forward from the Schönberg School, the post-1945 new music thereby opens up the spectrum of vocal expressions of sound beyond that of the singing voice. It does so not only for solo voices but for the choir as well.

    Full Text Available The article presents the use of historical Polish post-war topographic maps and their usefulness in the detection and assessment of environmental changes caused by 20th century urbanisation. The case study area is the Polish city of Lublin. Two main research questions are defined and answered. The first is what kinds of maps can be used to trace environmental changes as well as to find the present-day remains of past environments and what is the reliability of these maps? Several series of topographic maps are used here together with aerial photography. The second research question is what changes can be found by comparing spatial sources and what features can be found today with the help of early maps. The main features investigated in this section are linear (road networks and areal (orchards supplemented with point features of various kinds (trees, wells, shrines. The quality of cartographic information is assessed and remnants of the past environment are discovered.

  6. The Concerns Underlying Sex Education for Young People in France During the First Half of the 20th Century: Morality, demography and public health

    Virginie De Luca Barrusse

    2011-01-01

    Full Text Available During the first half of the 20th century, the issue of sex education for young people was the topic of virulent debate. Increasing proposals for sex education in schools, along with lectures and information leaflets, were quickly opposed by Catholic circles, which did not reject sex education in principle but sought to control its form and content. Yet no matter which form or content was chosen, sex education remained underpinned by considerations about the future of the population and the state of public health, particularly the resurgence of syphilis, as well as moral principles. The concerns underlying sex education were morality, demography and public health, which set limits on what was desirable and undesirable in this area and guided the objectives it was to achieve. Sex education was therefore conceived as an instrument for the reproduction and preservation of the race but was not supposed to become an instrument of debauchery. This is confirmed by an analysis of the proposed systems, which differed according to the sexes.

  7. Energy feedbacks of northern high-latitude ecosystems to the climate system due to reduced snow cover during 20th century warming

    The warming associated with changes in snow cover in northern high-latitude terrestrial regions represents an important energy feedback to the climate system. Here, we simulate snow cover-climate feedbacks (i.e. changes in snow cover on atmospheric heating) across the Pan-arctic over two distinct warming periods during the 20th century, 1910-1940 and 1970-2000. We offer evidence that increases in snow cover-climate feedbacks during 1970-2000 were nearly three times larger than during 1910-1940 because the recent snow-cover change occurred in spring, when radiation load is highest, rather than in autumn. Based on linear regression analysis, we also detected a greater sensitivity of snow cover-climate feedbacks to temperature trends during the more recent time period. Pan-arctic vegetation types differed substantially in snow cover-climate feedbacks. Those with a high seasonal contrast in albedo, such as tundra, showed much larger changes in atmospheric heating than did those with a low seasonal contrast in albedo, such as forests, even if the changes in snow-cover duration were similar across the vegetation types. These changes in energy exchange warrant careful consideration in studies of climate change, particularly with respect to associated shifts in vegetation between forests, grasslands, and tundra. ?? 2007 Blackwell Publishing Ltd.

    Full Text Available The aim of the paper is to present the development of sections and features in newspapers published in Osijek from mid-19th to mid-20th century. The paper focuses on the establishment, development and shaping of sections, i.e. their setting, headings, name changes, change patterns, graphic and typographical solutions, etc. The research was conducted in the Newspaper Collection of the Museum of Slavonia. It was based on two criteria: years of publication and cultural importance, and included the following newspapers: Die Drau, Slavonische Presse, Narodna (Hrvatska obrana and Hrvatski list. The research results prove that newspaper sections and features are only in the initial stage of development as a concept of newspaper content organization. Their names are mostly highlighted graphically as sub-headings on a page, often not systematically. The more important news is often not embedded in feature sections - features are a content element and not an organizational category. They often gather related information and occur only when there’s a sufficient amount of particular type of information. The paper takes a fresh look at investigating the history of Croatian newspapers, showing not only the development of sections and features, but also how research of this type can help reconstruct social change and the way it is reflected in daily newspapers, as we can assume that a new section or feature is introduced only when there is increased interest or sufficient attention of the public to a particular topic.

    We use human-skeleton samples to estimate the height of adults living in Anatolia during the Neolithic period. We also report the results of surveys taken in the 20th century on the height of the Turkish population. Neolithic and the Chalcolithic (5000-3000 B.C.) male heights are estimated as 170.9 cm and 165.0 cm, respectively. Pronounced increases were observed for both sexes between the Chalcolithic and Iron (1000-580 B.C.) periods and sharp decreases among both males and females in the Hellenistic-Roman period (333 B.C. to 395 A.D.). Moreover, recovery to the Iron Age levels was achieved in the Anatolian Medieval period (395-1453 A.D.) for both sexes (169.4 cm for males and 158.0 cm for females). In 1884 the mean height of men was 162.2 cm and by the beginning of the 1930s it increased to 166.3 cm. In the first nationwide survey in 1937 males mean height was 165.3 cm, and females was 152.3 cm, where today current heights are 174.0 cm and 158.9 cm, respectively. PMID:21316315

    Ocelots (Leopardus pardalis) in the United States currently exhibit low levels of genetic diversity. One hypothesis for this observation is that habitat fragmentation, resulting from human induced changes in the landscape during the 20(th) century, created island populations with highly reduced gene flow and increased genetic drift and inbreeding. In an effort to investigate this, we used a portion of the mitochondrial control region and 11 autosomal microsatellite loci to examine historical levels of genetic diversity and infer temporal changes in ocelot populations between 1853 and 2005. Levels of genetic diversity were higher in historical ocelot populations than in extant populations from Texas. The earliest documented loss of mitochondrial haplotype diversity occurred at Laguna Atascosa National Wildlife Refuge. The second extant population inhabiting private lands in Willacy County retained higher levels of genetic diversity through the 1990s, but subsequently lost diversity over the next decade. A similar pattern was observed for autosomal microsatellite loci. This supports the argument that low levels of genetic diversity in Texas are related to human induced population reductions and fragmentation, both of which threaten the remaining ocelots in the United States. At this time, the best means of mitigating the continued erosion of genetic variation are translocation of individuals either from larger populations in Mexico to Texas, or between the Texas populations.

    2015-05-01

    Full Text Available This article presents the development of recruitment and education of police trainees in Sweden during the 20th century. The aim is to analyse the efforts to promote a role for the police and a police force that would be more social, representative and intellectual. While this has been the goal during the last ten to fifteen years, this investigation shows that the roots of these efforts go back to the 1930s. The ideas underlying recruitment originally sought the ideal police among soldiers, a foundation that metamorphosed into the desire to attract men from different social and occupational groups, and finally developed into attempts at including more women and immigrants. Gradually, police education has been prolonged with an orientation and introduction, plus increased instruction in theoretical subjects such as the social sciences, psychology and Swedish. The conclusion is that more research is needed in other countries as well, because knowledge about changes in recruitment and education can make a valuable contribution to the general field of police history.

    This article traces prostitution in al-Mahalla in the first half of the 20th century as a regulated urban practice until the trade was outlawed in Egypt in 1949. Studying prostitution during this period of exceptionally rapid growth and transformation not only provides a window on a particular type of illicit sexuality and public morality in a colonial context, it also gives us a hint as to gender relations and inter-communal relations on the invisible marginalized part of a provincial local community, and how it was socially transformed. I argue that the regulation of prostitution in Egypt in 1882 and 1905 created a sphere for a power contest between the colonial state and the local community, between nationalist discourse and the local way of life, and between public morality and private space. While nationalist discourse constructed one virtuous nation, the local community accepted the licensed prostitution quarter, and resisted secret prostitution. The people of the town actively and continually shifted boundaries on what was public and what was private, what was the state's responsibility and what was communal liability.

    Full Text Available How did intellectuals react to the economic crisis of 2007-2008 and its long-term backlash? What did they learn from the main twentieth-century political and social experiences, in order to make a new sense of the traditional cultures of the Left? In order to answer these crucial issues, this proposal will analyze the paths of the well-known historians E. Hobsbawm and T. Judt and their apparently similar, but actually different reactions to the crisis. First, I will focus on their respective books: How to Change the World (2011 and Ill Fares the Land (2010. On the one hand, Hobsbawm’s critical approach to the post-1991 world, shaped by his lifelong fidelity to Marxism and his persistent sympathy for the Russian Revolution, was connected to his catastrophic vision of the end of the both conflicting and collaborative dynamics between capitalism and socialism. On the other hand, Judt’s re-thinking of the social-democratic tradition, compelled by the global transformations of the social question, was inspired by his connections with the East Central European dissidents’ anti-totalitarian liberalism and by his critical approach to the engagement of the French intellectuals. Second, I will investigate their different interpretations of the „Golden Age“ of post-1945 Europe (with special regard to the long-term impact of the crisis of 1929 and to the influence of Soviet communism and of the causes of its crisis. Third, I will show how, in spite of their common reference to Marx, late Hobsbawm’s and Judt’s historical visions - respectively combined with determinism and moralism - provide opposite ways of coping with the legacies of the 20th century and of criticizing the language of neoliberal economy within the Left.

    Full Text Available Interannual-to-decadal variability in stratospheric ozone and climate have a number of common sources, such as variations in solar irradiance, stratospheric aerosol loading due to volcanic eruptions, El Niño Southern Oscillation variability and the quasi-biennial oscillation (QBO. Currently available data records as well as model simulations addressing stratospheric chemical climate variability mostly cover only the past few decades, which is often insufficient to address natural interannual-to-decadal variability. Here we make use of recently reconstructed and re-evaluated data products to force and validate transient ensemble model simulations (nine members across the twentieth century computed by means of the chemistry-climate model SOCOL. The forcings included sea surface temperatures, sea ice, solar irradiance, stratospheric aerosols, QBO, changes in land properties, greenhouse gases, ozone depleting substances, and emissions of carbon monoxides, and nitrogen oxides. The transient simulations are in good agreement with observations, reconstructions and reanalyses and allow quantification of interannual-to-decadal variability during the 20th century. All ensemble members are able to capture the low-frequency variability in tropical and mid-latitudinal total ozone as well as in the strength of the subtropical jet, suggesting a realistic response to external forcings in this area. The region of the northern polar vortex exhibits a large internal model variability that is found in the frequency, seasonality, and strength of major warmings as well as in the strength of the modeled polar vortex. Results from process-oriented analysis, such as correlation between the vertical Eliassen Palm flux (EP flux component and polar variables as well as stratospheric ozone trends, are of comparable magnitude to those observed and are consistent in all analysed ensemble members. Yet, trend estimates of the vertical EP flux component vary greatly among

    Terrestrial vegetation currently absorbs approximately a third of anthropogenic CO2 emissions, mitigating the rise of atmospheric CO2. However, terrestrial net primary production is highly sensitive to atmospheric CO2 levels and associated climatic changes. In C3 plants, which dominate terrestrial vegetation, net photosynthesis depends on the ratio between photorespiration and gross photosynthesis. This metabolic flux ratio depends strongly on CO2 levels, but changes in this ratio over the past CO2 rise have not been analyzed experimentally. Combining CO2 manipulation experiments and deuterium NMR, we first establish that the intramolecular deuterium distribution (deuterium isotopomers) of photosynthetic C3 glucose contains a signal of the photorespiration/photosynthesis ratio. By tracing this isotopomer signal in herbarium samples of natural C3 vascular plant species, crops, and a Sphagnum moss species, we detect a consistent reduction in the photorespiration/photosynthesis ratio in response to the ∼100-ppm CO2 increase between ∼1900 and 2013. No difference was detected in the isotopomer trends between beet sugar samples covering the 20th century and CO2 manipulation experiments, suggesting that photosynthetic metabolism in sugar beet has not acclimated to increasing CO2 over >100 y. This provides observational evidence that the reduction of the photorespiration/photosynthesis ratio was ca. 25%. The Sphagnum results are consistent with the observed positive correlations between peat accumulation rates and photosynthetic rates over the Northern Hemisphere. Our results establish that isotopomers of plant archives contain metabolic information covering centuries. Our data provide direct quantitative information on the "CO2 fertilization" effect over decades, thus addressing a major uncertainty in Earth system models. PMID:26644588

    In Chinese free werse of the 20th century, "the motherland" (or"China")is a common image, as a result of China's destiny ups and downs in 20th century, "mother land's" image connotation in free poetry also changes. By the end of Qing Dynasty, motherland was the mountains and rivers broken as well as Chinese territory overrun and occupied by the enemy; During May Forth Movement, motherlan is"the nirvana phoenix", "youth China", "motherland like flower's"; During 1920's and 1930's China is" the nightmare hanging from cliff","a ditch despairs stagnant water"; During Sino-Japanese War, motherland is"coldly blocking China", covers entirely by" the blood and the muds"; After the liberation, great motherland is grand"Tian'an men",the bright"Five-Starred Red Flag"and the great leader; Since the new time,motherland's connotation has been richly colorful, not only"riverside worn-out old waterwheel"but also"the crimson daybreak", prosperous" scaffold"and" railway line"" the language and the quarry stone throw build" the spiritual home;In overseas Chinese eyes, motherland is"specially anchors of Chinese local accent" "the Chinatown" ,several millennium bright cultures"sad kind nurses with hardship""the Baiyu balsam pear".%"祖国"(或"中国")是二十世纪中国诗歌中常见的一个意象,由于二十世纪中国命运的坎坷多变,诗歌中"祖国"意象的内涵也与时俱变.清末诗歌中的祖国是山河破碎、神州陆沉;五四的祖国是"涅槃的凤凰"、"少年中国"、"如花的祖国";二、三十年代的中国是"噩梦挂着悬崖"的"一沟绝望的死水";抗战期间的祖国是被"寒冷封锁着的中国"、布满"血和泥"的中国;解放后的伟大祖国,是雄伟的"天安门"、鲜艳的"五星红旗"和伟大领袖;新时期以来的祖国,其内涵丰富多彩,既是"河边破旧的老水车",也是"绯红的黎明",欣欣向荣的"脚手架"和"铁道线",又是"语言和乱石投筑"的精神家园;在海外华人眼中,祖国则

  1. Adventurers, Flaneurs, and Agitators: Travel Stories as Means for Marking and Transgressing Boundaries in 19th and Early 20th Century Finland

    Full Text Available The article focuses on border crossings in travel stories, which were published in hand-written newspapers in 19th- and early 20th-century Finland. These papers were a popular tradition in student organizations and popular movements. Border crossings appear in travel stories in three different representations. Firstly, border crossings are repeated motifs in travel stories, both as challenging events and as small gestures and encounters. Travel stories demarcate boundaries, but they also provide a means for transgressing them. Secondly, hand-written newspapers as a literary practice highlight borders between oral and written communication. They were produced as one single manuscript copy, and published by being read out aloud in social events. Thirdly, the authors of hand-written newspapers were placed on the border of different positions in society such as class, gender and age. My analysis is based on the methodological discussion of small stories and personal experience narratives; travel stories can be defined as "local event narratives". I have outlined four basic models for travel stories which emerge from hand-written newspapers: the great mission story, the grand tour story, the flaneur story and the retreat story. The analysis of travel stories is presented through four different case studies with a time range from the 1850s to the 1920s: these materials have been produced in two provincial student fraternities (osakunta, in the temperance society "Star" in Helsinki in the 1890s, and in the Social Democratic Youth Club in the small industrial town of Karkkila in the 1910s and the 1920s. Many parallel features can be observed in travel stories, even though the social background and ideology of the authors are quite different. Time and space are important aspects in travel stories, and they often demarcate boundaries of class and gender.

    Landscape spatial pattern mainly refers to the distribution of patches, which are different in size and shape in space owing to the interaction of various ecological activities. In landscape ecology study, landscape pattern has been one of the key study areas. Water body landscape plays an important role in the development history of a city, but at present city water body landscape in many cities has been destroyed, hence protecting water body in the city is becoming more and more important. In order to protect city water body landscape reasonably, the precondition is to probe the dynamics of water body landscape. Based on historical data and remote sensing data, six indexes including patch number, patch area, landscape dominance index, fractal dimension, patch density and connectivity index etc. were used to analyze landscape pattem dynamics of water body in Kaifeng city since the end of the Qing Dynasty (in the 20th century). The results showed: (1) Since the end of the Qing Dynasty, landscape area of water body in Kaifeng city increased first and then decreased from 1898 to 2002AD; the landscape dominant degree had the same changing tendency with the area. (2) Patch number of water body landscape in Kaifeng city had an increase from 1898 to 2002, but maximum area of patch, minimum area of patch and average area of patch decreased, which resulted in an increase in landscape fragment degree. (3) Connectivity index decreased and fractal dimension increased from 1898 to 2002. The reasons for these changes were the repeated overflows and flooding of the Yellow River and the influence of human activities.

    美国一直很重视对移民的同化,公民教育是移民同化采用的非常重要的手段。为此,20世纪中期美国采取了一系列相应的措施,其实践探索值得研究。美国成人移民公民教育的基本理念是帮助非美国公民身份的成人移民通过入籍考试,加入美国国籍,并培养他们对美国文化和价值观的认同感,使之与整个社会结合成一个团结而统一的整体。为实现这一目标,公立学校、移民归化局和其他一些机构相互配合,共同努力,取得了显著的成效。%They always pay much attention to assimilation of immigrants in the United States, the very important as- similation way is citizenship education. They took a series of measures of citizenship education for adult immigrants in Mid -20th Century in America, which is worth researching for us. The fundamental concept of citizenship education for adult immigrants was to help non- Americans of adult immigrants pass American Citizenship Test and be Americans, and train them to identify American culture and outlook of American value, then make them and the society as a unite and unified whole. To fulfill the objective, the public schools, U.S. Immigration and Naturalization Service and other organizations cooperated and worked hard together. At last, their work was very effective.

  4. Over the hills and further away from coast: global geospatial patterns of human and environment over the 20th-21st centuries

    Proximity to the coast and elevation are important geographical considerations for human settlement. Little is known, however, about how spatial variation in these factors exactly relates to human settlements and activities, and how this has developed over time. Such knowledge is important for identifying vulnerable regions that are at risk from phenomena such as food shortages and water stress. Human activities are a key driving force in global change, and thus detailed information on population distribution is an important input to any research framework on global change. In this paper we assess the global geospatial patterns of the distribution of human population and related factors, with regard to the altitude above sea level and proximity to the coast. The investigated factors are physical conditions, urbanisation, agricultural practices, economy, and environmental stress. An important novel element in this study, is that we included the temporal evolution in various factors related to human settlements and agricultural practices over the 20th century, and used projections for some of these factors up to the year 2050. We found population pressure in the proximity of the coast to be somewhat greater than was found in other studies. Yet, the distribution of population, urbanisation and wealth are evolving to become more evenly spread across the globe than they were in the past. Therefore, the commonly believed tendency of accumulation of people and wealth along coasts is not supported by our results. At the same time, food production is becoming increasingly decoupled from the trends in population density. Croplands are spreading from highly populated coastal zones towards inland zones. Our results thus indicate that even though people and wealth continue to accumulate in proximity to the coast, population densities and economic productivity are becoming less diverse in relation to elevation and distance from the coast.

    20世纪德国的发展轨迹极为典型。自从1871年俾斯麦统一德国后,德国借着国家统一和两次工业革命的东风,迅速崛起,一跃成为当时的资本主义强国之一。随后德国相继经历了战争、战败、再复兴、再挑起战争、再战败。在二战后,德国终于跳出战争怪圈,与其欧洲邻国启动欧洲一体化进程,成就了今天德国的大国地位。德国的发展特别是二战后再度迅速崛起有许多值得中国借鉴的地方,尤其在崛起方式、统一问题、外交选择和文化实力等方面。%The developing track of German is a typical one in the 20th century. After Bismarck unified German in 1871, it became one of the strongest capitalist countries by means of its unification and the two industrial revolutions. Then German experienced the World War I, being defeated and its renaissance. And then it provoked the World War II and was defeated again. After World War II, German finally jumped out of the vicious circle of war and with its neighbor countries promoted the development of European Integration, and achieved its status of great power today. German’s development, especially which after World War II, its developing track has great reference value to China, especially in the way of rising, unification, diplomacy and cultural power.

    Full Text Available Purpose: Travelling library service is a field of librarianship which has not been thoroughly explored yet either in Slovenia or abroad. The most interesting question is who the beginner was and how the idea of a travelling library service has been introduced to Slovenia.Methodology/approach: The analysis of primary and secondary resources served to represent the life and work of Lovro Stepišnik as well as a short introduction to the history of travelling librarianship in Slovenia at the turn of the 19th to the 20th century.Results: The findings show that the hypothesis on Lovro Stepišnik as the first travelling librarian in Slovenia could be confirmed. After establishing the library together with the Reading society in the year 1863, either Stepišnik or his assistant, delivered baskets of books to rural readers. At the same time, some initiatives on private travelling libraries based on American and European practices emerged. The aim of the first travelling libraries was to stimulate reading and literacy among rural population, especially in the areas without reading societies and on the borders with German speaking population,in order to stimulate national consciousness and the use of the Slovenian language.Research limitation: The research was limited to the selected primary resources of selected serial publication in the Slovenian language. Some difficulties due to the variety of terms and archaic expressions were identified.Originality/practical implications: The short study should stimulate the research in the development of travelling libraries in Slovenia.

    近代以来, 作为中国传统文化一脉的风水观因其缺乏 "真确的知识" 而受到摒弃和批判, 五四以来风水一直受到科学理性、 唯物主义主导的文学思潮的攻伐. 随后, 20世纪中国社会及文化思潮发生了巨大的变迁,风水在文学中的境遇也因时而易, 这不但反映了时代思潮的嬗变, 还纠结着20世纪纷繁复杂的政治、 哲学及美学取向. 尤其是随着90年代中国文化语境的变迁, 风水文化逐渐浮现出其反思现代性的 "复魅" 特质.%In modern times, Feng Shui, which has been inherent to traditional Chinese culture, has been denounced and defamed as lack of scientific and truthful knowledge, and has long been criticized by the rational and materialistic school of literature since the May Fourth Movement. In the 20th century, as the Chinese society and ideology is undergoing dramatic changes, Feng Shui varies from time to time in literature, which reflects not only the transformation of ideology but also the complication of politics, philosophy and aesthetics. Particularly in the 1990s, as the cultural environment in China has greatly changed, the culture of Feng Shui tends to be charged with the nature of "revitalizing the enchantment of the world", i. e. reflections upon modernism.

    The motion of the Earth's pole in space has been observed with great accuracy for the last 115 years. The angular variations of the pole position away from its mean are a well explained at annual and 434-day periods. Variations at annual periods are caused by changes in the mass and angular momentum forced by all Earth surface changes that have near seasonality. The 434-day period is explained as a resonance between the cumulative driving forces having periods near the Chandler wobble free eigenmode of the Earth and is well understood theoretically. The Earth also has a longer-term drift that is explained primarily as a response to the ice age changes in the moments of inertial of the Earth. However, there has been a long-standing search for the origins of pole variations that have a period near 10 years. Using GRACE space gravimetry we show that ice mass losses from Greenland and Antarctica, and when combined with changes in continental hydrology, explain almost all the main features of interannual time scale polar wander. The discovery has broad interdisciplinary implications, as we show that decadal scale pole variations are directly linked to global changes continental water. The energy sources for these pole position changes are, therefore, likely to be associated with decadal scale ocean and atmospheric oscillations that also drive 20th Century on-land wet-dry oscillations at decadal-scale across the globe. Variability in pole position, therefore, offers a tool for assessing past stability of our climate, and for the future, now faced with an increased intensity in the water cycle and more vulnerable to ice sheet instability.

    . Altogether 263 bookshops were founded in the second half of the 19th and at the beginning of the 20th century and 283 persons became bookshop owners (at least for some years. These figures allow to conclude that book trade was a popular sphere of activity. The most intensive was foundation of bookshops during 1898–1904. Legally it was not difficult to get a permission to open a bookshop but only few shops (31% operated more than ten years; most often was that small shops operated up to five years. Trading with books did not guarantee sufficient income and the bookshop owners were often engaged in other spheres, mainly in book production and publishing. Majority of the Estonian origin bookshop owners derived from the peasant families and made up the first generation in book trade business. The newcomers had not enough education nor experience in the field. The most important achievement can be seen in the fact that bookshops were opened in all over Estonia that guaranteed dissemination of Estonian language books to all stratums of the society.

    In recent decades air temperature (Ta) has been increasing steadily around the globe and it is reported that in the last 40 years Ta in Mongolia alone has increased by about 2.1 deg.C. The boreal region as a whole is expected to experience changes due to atmospheric drying, permafrost degradation, increases in the frequency of forest fires and other factors that will lead to a shift of the forest ecosystems northward. The southern border of the boreal forest distributes in northern Mongolia and northeast China, which as transition areas are more sensitive to changes. In a 500 km long south-north transect of larch forests extending in each of these two countries, larch forest sites were chosen (Larix sibirica in Mongolia and Larix gmeliini in China). Studies until now have used only tree-ring analysis to determined past and recent climate in Mongolia and China. However, isotope analysis has not been coupled with this analysis to give a wider overview of the environmental changes taking place in these regions. Therefore in this study tree core samples were collected for tree-ring and carbon isotope analysis to be coupled with available meteorological data. These data indicate that in the last four decades, the northernmost site of the selected transect has experienced the largest increase in Ta, but nevertheless the annual Ta in the southernmost site remained several degrees higher. On the other hand precipitation shows a very slight increase in the central and northernmost sites while an insignificant decrease is observed in the southernmost site. Tree-ring analysis shows that for most of the 20th century tree ring growth had lower inter-annual variability until the beginning of the 1970's but from then on the annual variability has increased. Unlike the results of the tree-ring analysis, the carbon isotope analysis revealed that until the 1970's the increases in the drying atmospheric conditions (higher temperature-no changes in rainfall) were not present but the

    Socioeconomic developments increasingly put pressure on our global fresh water resources. Over the past century, increasing extents of land were converted into (irrigated) agricultural production areas whilst dams and reservoirs were built to get grip on the timing and availability of fresh water resources. Often targeted to be of use at local, regional, or national levels, such human interventions affect, however, terrestrial water fluxes on larger scales. Although many of these interventions have been studied intensively at global and regional scales, the impact of land use and land cover change has often been omitted, and an assessment on how land conversions impact water resources availability and water scarcity conditions was not executed before, despite its importance in the development of sound integrated river basin water management plans. To address this issue, we evaluate in this contribution how land use and land cover change impact water resources and water scarcity conditions in the 20th century, using a multi-model multi-forcing framework. A novelty of this research is that the impact models applied in this study use the dynamic HYDE 3.1 - MIRCA dataset to cover the historical (1971-2010) changes in land use and land cover. Preliminary results show that more than 60% of the global population, predominantly living in downstream areas, is adversely affected by the impacts of land use and land cover change on water resources and water scarcity conditions. Whilst incoming discharge generally (in 97% of the global land area) tends to decrease due to upstream land conversions, we found at the same time increases in local runoff levels for a significant share (27%) of the global land area. Which effect eventually dominates and whether it causes water scarcity conditions is determined by the dependency of a region to water resources originating in upstream areas, and by the increasing rates with which the (locally generated) stream flow is used to fulfil (non

    Full Text Available This paper aims at retracing the important phases of migrations in the alpine regions and the Jura from the Middle Ages up to the middle of the 20th century. Migration has always functioned as a necessary complement to the resources of the inhabitants of the upland regions and it increases when the economic disparity with the lowlands becomes more marked. A striking characteristic of such migration is the great diversity that can be observed, since not only the destinations of the migrants varied from community to community, but also different forms of mobility coexisted within the same territory. Migration might be seasonal, pluriannual, lifelong or even definitive. It is also notable that the various types of migration can be observed to be part of a plurisecular tradition, apart from some significant exceptions, such as the emigration of the Walser, enforced migrations and the new types of migration as from the second half of the nineteenth century. The mobility of part of the population was also a consequence of modifications deriving from changes in the prevalent type of production (animal husbandry instead of the cultivation of cereals, as well as from demographic factors. In addition to these factors one can observe the role played by political institutions throughout the period under study: seigneurial power in the Middle Ages, the communal and cantonal instances until the second half of the nineteenth century, and afterwards the federal authorities.Cette contribution vise à montrer les grandes phases des mouvements migratoires du Moyen Age au milieu du XXe siècle dans les mondes alpin et jurassien suisses. La migration a toujours été une complémentarité nécessaire aux ressources de la montagne, et elle s'amplifie lorsque les disparités économiques avec le plat pays s'accroissent. Elle se caractérise par une forte diversité, puisque non seulement les destinations et les aires d'établissement des migrants peuvent varier

    Public health policy underwent substantial transformation during the latter half of the 20th century. The landmark statement was the 1948 World Health Organization (WHO) constitution, which identified good health as a fundamental right and gave the responsibility to governments to achieve it for all their people. However, following World War II, developed countries made substantial investment in health care with less attention paid to public health. The importance of public health was slowly recognised over the period from 1970 to 2000 with the publication of several reports from different organisations. The first authoritative policy statement that the important determinants of health lay outside health care was in the Lalonde Report from Canada. These ideas were subsequently expressed in the WHO Alma-Ata declaration and were emphasised a year later by the US Surgeon General. The idea of setting goals for health improvement also began in the 1970s. The Lalonde Report and the United Kingdom Black Report recommended that targets be used, but the first explicitly stated health targets were set by the US in 1979. WHO also identified the need for such targets at this time, but did not introduce them until 1984. Since then health targets have become a central feature of public health policy in developed countries. The Ottawa Conference on Health Promotion in 1986 championed the view that health promotion was central to achieving health goals internationally. It helped clarify the types of actions needed: that individuals need to be provided with the supportive environment and economic resources to be able to lead healthy lives. In a further development, the Healthy Cities Project was launched with the specific aim of involving political decision-makers in building a strong lobby for public health at the local level. The Healthy Cities Project illustrates how to provide means and opportunity for interventions to be implemented in communities. Concerns with inequalities

    The Adriatic Sea and the Black Sea are two semienclosed basins connected to the Mediterranean Sea by the Otranto and the Bosporus straits, respectively. This work aims to reconstruction the sea level for both basins in the 20th century and to investigate main sources of interannual variability. Using 7 tide gauge timeseries located along the Adriatic coast and 5 along the Black Sea coast, provided by the PSMSL (Permanent service of mean sea level), a seamless sea level timeseries (1900-2009) has been obtained for each basin on the basis of statistical procedure involving PCA and Least Square Method. The comparison with satellite data in the period 1993 - 2009 confirms that these are reliable representations of the observed sea level for the whole basin, showing a great agreement with a correlation value of 0.87 and 0.72 for Adriatic and Black Sea respectively. The sea level has been decomposed in various contributions in order to analyze the role of the factors responsible for its interannual variability. The annual cycles of the local effect of pressure (inverse barometer effect IB), of the steric effect due to temperature and salinity variation and of the wind effect have been computed. The largest contribute for the Adriatic Sea is due to the wind, whilst inverse barometer effect plays a minor role and the steric effect seems to be almost negligible. For the Black Sea, on the contrary, wind effect is negligible, and the largest source of variability is due to the Danube river, which is estimated from the available discharge data of Sulina (one of the exits of the Danube delta. Steric and IB effects play both a minor role in this basin. A linear regression model, built considering as predictor the SLP gradient identified at large scale after having carried out the correlation analysis, is capable to explain a further percentage of variability (about 20-25%) of the sea level after subtracting all the factors considered above. Finally, residual sea levels show a

    Since the late 18th century, the Korean traditional medicine trade witnessed a steady growth. There were lots of stores which sold Korean medicinal herbs in Seoul and every major towns had at least one or more stores in Korea, which led to a subsequent growth of people involved in the trade. However, Korean medicine merchants encountered a new environment with the influx of western medicines after the Opening of Ports and the execution of modern medicine policies. Such change of atmosphere led the merchants to seek new breakthroughs. Some of the merchants found the answer in producing and selling patent medicine. The people in the industry had little knowledge of western medicine, so that they had little choice but to combine their experience of Korean medicine with whatever information they had about western counterpart. Such resolution generated a new kind of medicine known as patent medicine. Patent medicine businessmen observed the new medicine policies of the Korean Empire. Some visionary ones even sought to eagerly utilize the trademark system to secure the selling route. The Japanese colonial government strengthened the medicine policies. It revised the legislature and mobilized administrative powers to manage and control the industry. However, such colonial policies in the 1910s implicated certain limits due to its lack of understanding of Korean medicine industry. Also, the colonial government showed poor efforts in introducing modern medicine facilities and systems, so that the ground was set for the patent medicine business to flourish. Patent medicine enjoyed a high turnover. So, the entrepreneurs endeavored to promote the sales in whatever means necessary. The most basic form of advertisement was through the newspaper. Indirect promotion through newspaper articles, issuing medicine flyers, free gift draw, reputation of an influential expert were widely used for its sales. Consequently, patent medicine industry in the 1910s saw a healthy prosperity. One

    Historical flood data series of Eastern Spanish Coast (14th-20th centuries). Improving identification of climatic patterns and human factors of flood events from primary documentary sources Armando Alberola, Barriendos, M., Gil-Guirado, S., Pérez Morales, A., Balasch, C., Castelltort, X., Mazón, J., Pino, D., Ruiz-Bellet, J.L., Tuset, J. Historical flood events in eastern spanish coast have been studied by different research groups and projects. Complexity of flood processes, involving atmospheric, surface and human factors, is not easily understandable when long time series are required. Present analysis from PREDIFLOOD Project Consortium defines a new step of flood event databases: Improved access to primary (documentary) and secondary (bibliographical) sources, data collection for all possible locations where floods are detected, and improved system of classification (Barriendos et al., 2014). A first analysis is applied to 8 selected flood series. Long chronologies from PREDIFLOOD Project for Catalonia region (Girona, Barcelona, Tarragona, Lleida, Tortosa). In addition, to cover all sector of spanish mediterranean coast, we introduce Valencia city in Turia River basin. South Eastern sector is cover with Murcia and Caravaca cities, Segura River basin. Extension of area under study required contributions of research teams experienced in work of documentary primary sources (Alberola, 2006; Gil-Guirado, 2013). Flood frequency analysis for long scale periods show natural climatic oscillations into so-called Little Ice Age. There are general patterns, affecting most of basins, but also some local anomalies or singularities. To explain these differences and analogies it is not enough to use purely climatic factors. In this way, we analyze human factors that have been able to influence the variability of floods along last 6 centuries (demography, hydraulic infrastructures, urban development...). This approach improves strongly understanding of mechanisms producing

    There is substantial evidence that soil thermal dynamics are changing in terrestrial ecosystems of the Northern Hemisphere and that these dynamics have implications for the exchange of carbon between terrestrial ecosystems and the atmosphere. To date, large-scale biogeochemical models have been slow to incorporate the effects of soil thermal dynamics on processes that affect carbon exchange with the atmosphere. In this study we incorporated a soil thermal module (STM), appropriate to both permafrost and non-permafrost soils, into a large-scale ecosystem model, version 5.0 of the Terrestrial Ecosystem Model (TEM). We then compared observed regional and seasonal patterns of atmospheric CO2 to simulations of carbon dynamics for terrestrial ecosystems north of 30??N between TEM 5.0 and an earlier version of TEM (version 4.2) that lacked a STM. The timing of the draw-down of atmospheric CO2 at the start of the growing season and the degree of draw-down during the growing season were substantially improved by the consideration of soil thermal dynamics. Both versions of TEM indicate that climate variability and change promoted the loss of carbon from temperate ecosystems during the first half of the 20th century, and promoted carbon storage during the second half of the century. The results of the simulations by TEM suggest that land-use change in temperate latitudes (30-60??N) plays a stronger role than climate change in driving trends for increased uptake of carbon in extratropical terrestrial ecosystems (30-90??N) during the recent decades. In the 1980s the TEM 5.0 simulation estimated that extratropical terrestrial ecosystems stored 0.55 Pg C yr-1. with 0.24 Pg C yr-1 in North America and 0.31 Pg C yr-1 in northern Eurasia. From 1990 through 1995 the model simulated that these ecosystems stored 0.90 Pg C yr-1, with 0.27 Pg C yr-1 stored in North America and 0.63 Pg C yr-1 stored in northern Eurasia. Thus, in comparison to the 1980s, simulated net carbon storage in the

    Full Text Available The topic of this article is the literary discourse of Young Estonia; its relations with other important Estonian literary discourses from the beginning of the 20th century, and its relations with colonial cultural discourse. First, I give an overview of the basic positions of the Young Estonians’ literary discourse, the main shapers of which were Friedebert Tuglas, Gustav Suits, later on Johannes Semper as well. Next, I present the basic principles of three Estonian literary discourses from the beginning of the 20th century, which were also important to the Young Estonians: nationalist-naturalistic (close-to-life; socialist/ class-based, and 20th century modernist. The Young Estonians began as nationalists and/or socialists. During the formation of Young Estonia’s discourse at the end of the first and beginning of the second decade of the 20th century, 20th century modernism began, which the Young Estonians regarded first and foremost with irony. The Young Estonians’ literary discourse is a mixture of aestheticism, decadence, symbolism, romanticism, and classicism. The point of departure for the Young Estonian approach to literature was eurocentrism. They took a superior and negative view of existing Estonian literature, which they regarded as having fallen drastically behind Europe. Since it was unable to build on its own foundation, it had to borrow from Europe. The discourse’s understandings of cultural values – theory, reading, knowledge, ready-made culture, derive from the centrality of the dynamic of borrowing. New culture could be created freely, without the support of previous local tradition; it was to be an elite culture, while the writer remained an individualist. Literature was to follow the principle of art for art’s sake; aesthetics and the form of the work of art were basic criteria. The formal ideals of the work of art were classicist: unity, integrity (wholeness, harmony, order, logic, etc. Thirdly, I outline the

    The main goal of this work is to investigate which are the main factors determining interannual sea level variability of Baltic, Adriatic and Black seas, and to which extent the sea level of these three basins can deviate from the global mean. The three basins selected are semi-enclosed marginal seas connected with the adjacent seas by narrow straits. 13 sea level timeseries in Baltic Sea, 7 in Adriatic Sea and 5 in Black Sea provided by PSMSL, allowed us to compute a single seamless sea level timeseries representative for each basin from 1900 and for the entire 20th century, using statistical tools (PCA and Least Square method). Comparison with satellite data in the period 1993-2009, confirms that timeseries so computed are good representations of the observed sea level, with correlation values of 0.97, 0.87 and 0.72 for Baltic, Adriatic and Black Sea respectively. At basin scale the sea level has been decomposed in various contributions that have been separately analyzed: local effect of pressure, steric effect due to temperature and salinity variation, boundary forcing, wind effect and river discharge. The annual cycles and their variability, show that the largest contribution is due to the wind for the Adriatic Sea and for the Baltic Sea. In these two basins the inverse Barometer effect plays a minor role and the steric factor is almost negligible. The wind seems to play a negligible role on Black Sea, where the Danube river discharge plays an important role. A linear regression model, built considering large scale sea level pressure distribution as predictor, is capable to explain a further percentage of sea level variability variability (about 20%) left after subtracting all the factors considered above. Sea level of the Baltic and Black Sea show a significant positive correlation (0.3 about) revealing the likely influence of an external common forcing. Past sea level variability shows no strong evidences of large deviation from the global mean sea level

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

    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.

To demonstrate my point, I shall discuss two recent publications. First, I shall analyze the context of the convergence of racist and misogynist discourses in turn-of-the-century Vienna through discussing András Gerő’s book, Neither Woman Nor Jew.

The article proposes the author’s concept for classifying the reminiscences of participants in and witnesses of the peasant movement in Ukraine in the early 20th century. The author notes that memoir literature dedicated to the peasant movement can be examined through the prism of the proposed classification scheme, which will help get an answer to a number of questions posed in the procedure for analysis of reminiscences – the authorship-attribution of the source, the memoirist’s world-perception and views, the degree of proximity to events described, the degree of competence and logicalness of judgments, the author’s expression, operant motives for writing a memoir work, and the specific, genre, and stylistic nature of reminiscences – as well as identify their content fragments.

    Philanthropies funded by the Rockefeller family have been prominent in the social history of the twentieth century for their involvement in medicine and applied science. This book provides the first detailed study of their relatively brief but nonetheless influential foray into the field of mathematics. The careers of a generation of pathbreakers in modern mathematics, such as S.Banach, B.L.van der Waerden and André Weil, were decisively affected by their becoming fellows of the Rockefeller-funded International Education Board in the 1920s. To help promote cooperation between physics and mathematics Rockefeller funds supported the erection of the new Mathematical Institute in Göttingen between 1926 and 1929, while the rise of probability and mathematical statistics owes much to the creation of the Institut Henri Poincaré in Paris by American philanthropy at about the same time. This account draws upon the documented evaluation processes behind these personal and institutional involvements of philanthropies...

  1. [Power and everyday life in a lunatic asylum environment - a case example from Glasgow at the beginning of the 20th century].

    Science.gov (United States)

    Gründler, Jens

    In this article the focus of analysis lies on power relations in everyday life in one of Glasgow's Pauper Lunatic Asylums at the turn of the twentieth century. Taking a sample of patient case files I examine the daily processes of negotiation between inmates and their relatives, physicians, attendants and nurses as well as the poor law administration. Some cases especially exemplify the complex relationships between the actors. They show which opportunities and boundaries existed for "power brokering" for the more powerless. At the same time these cases illustrate the formal and practical limits of enforcement by doctors and nursing staff. Without turning a blind eve to hierarchies and power imbalances the analysis shows that even in settings like "total institutions" power remains volatile. Even there the more powerful actors have to actualize, seize and prevail on a regular basis. PMID:27501547

    Full Text Available The purpose of this investigation was to ascertain when the Italian Jewish communities and the Western Portuguese “Nations” adopted the nasal-guttural pronunciation of the ‘ayin, variously represented as gn, ng, ngh, hg. In 16th century Ferrara and Venice, the phonetic value of this consonant was zero or close to zero. Only at the very end of the 16th century, some authors in Italy graphically represented it as ng. In the same period, an Amsterdam author introduced new graphemes and expressed the ‘ayin as gh or hg, while a Hamburg scholar published a grammar-book where he gave the name of this consonant as Hgain. The new graphemes were not adopted by the majority of authors, who continued to represent it by a simple h, or left it without notation. Both in Italy and in Northern Europe, the h > gn shift was rather discontinuous.Estudio de la adopción de la pronunciación naso-gutural de la consonante ‘ayin y de su variada representación gráfica entre los judíos de Italia y de las «Naciones» judías hispano-portuguesas. Durante el siglo XVI, el valor fonético de esa consonante era o tendía a cero. A fines de ese siglo y a comienzos del XVII, algunos autores en Italia la representan como ng. Un autor coetáneo en Amsterdam introduce nuevos grafemas, tales como gh o hg, mientras que otro autor de Hamburgo publicaba una gramática en la que denomina Hgain esta consonante. Los nuevos grafemas no fueron adoptados por la mayoría de autores que continuaron representando dicha consonante por una h. Tanto en Italia como en el norte de Europa el cambio h > gn fue discontinuo.

    Climate drift in preindustrial control (PICTL) simulations can lead to spurious climate trends and large uncertainties in historical and future climate simulations in coupled models.This study examined the longterm behaviors and stabilities of the PICTL simulations in the two versions of FGOALS2 (the Flexible Global Ocean-Atmosphere-Land System model Version 2),which have been submitted to the Coupled Model Intercomparison Project Phase 5 (CMIP5).As verified by examining time series of thermal fields and their linear trends,the PICTL simulations showed stable long-term integration behaviors and no obvious climate drift [the magnitudes of linear trends of SST were both less than 0.04℃ (100 yr)-1] over multiple centuries.The changed SSTs in a century (that corresponded to the linear trends) were less than the standard deviations of annual mean values,which implied the internal variability was not affected.These trend values were less than 10% of those of global averaged SST from observations and historical runs during the periods of slow and rapid warming.Such stable long-term integration behaviors reduced the uncertainty of the estimation of global warming rates in the historical and future climate projections in the two versions of FGOALS2.Compared with the trends in the Northern Hemisphere,larger trends existed in the SST and sea ice extents at the middle to high latitudes of the Southern Hemisphere (SH).To estimate the historical and future climate trends in the SH or at some specific regions in FGOALS2,corrections needed to be carried out.The similar long-term behaviors in the two versions of FGOALS2 may be attributed to proper physical processes in the ocean model.

  4. Extinction of the northern oceanic deep convection in an ensemble of climate model simulations of the 20th and 21st centuries

    We study the variability and the evolution of oceanic deep convection in the northern North Atlantic and the Nordic Seas from 1850 to 2100 using an ensemble of 12 climate model simulations with EC-Earth. During the historical period, the model shows a realistic localization of the main sites of deep convection, with the Labrador Sea accounting for most of the deep convective mixing in the northern hemisphere. Labrador convection is partly driven by the NAO (correlation of 0.6) and controls part of the variability of the AMOC at the decadal time scale (correlation of 0.6 when convection leads by 3-4 years). Deep convective activity in the Labrador Sea starts to decline and to become shallower in the beginning of the twentieth century. The decline is primarily caused by a decrease of the sensible heat loss to the atmosphere in winter resulting from increasingly warm atmospheric conditions. It occurs stepwise and is mainly the consequence of two severe drops in deep convective activity during the 1920s and the 1990s. These two events can both be linked to the low-frequency variability of the NAO. A warming of the sub-surface, resulting from reduced convective mixing, combines with an increasing influx of freshwater from the Nordic Seas to rapidly strengthen the surface stratification and prevent any possible resurgence of deep convection in the Labrador Sea after the 2020s. Deep convection in the Greenland Sea starts to decline in the 2020s, until complete extinction in 2100. As a response to the extinction of deep convection in the Labrador and Greenland Seas, the AMOC undergoes a linear decline at a rate of about -0.3 Sv per decade during the twenty-first century.

However, because of many cultural and social differences between Chinese and Western, the entry of modernity into China faced many twists and variations. The Chinese literature was tied up in the way of modernization in 20th century, thus, its aesthetic characteristics and independent spirit were destined to be influenced by the specific historical society.

    Full Text Available The aim of this article is to provide an overview of translations of English literature into Estonian between 1779 and 1917. There is an attempt to analyse the texts by describing them on the basis of, or in their departure from, a text or texts that chronologically and logically precede them. The discussion includes the nature of the transfer and the changes that have been made to the text, either because they existed in the source or mediating text or because of the expectations or requirements in the receptor, i.e. Estonian culture. The translated texts are seen in their historical-cultural context. For the analysis, a corpus of translated texts – religious, fiction, drama and non-fiction (published in a book form was compiled. The general orientation of Estonia until the 1880s was to the German cultural sphere. So the first translations of English literature were made via a mediating language, which was German. English Puritan writers were introduced by the Pietist missionaries with the aim of spreading their teachings in the second half of the 18th century. At about the same time the narrative element was introduced into stories with religious content.

    To what degree does the built environment of cities shape the social environment? In this paper we use a Schelling-like agent based model to consider how changes to the built environment of cities relate to changes in residential segregation by income and ethnicity. To develop this model we exploit insights from a high resolution historical GIS which maps 100% of the population of Newark, NJ in 1880. Newark in 1880 had a complex social landscape characterized by areas of significant social and economic segregation and areas of relative integration. We develop a Schelling model capable of reproducing these residential patterns. We use this model to explore the decentralization of housing, a specific phenomenon associated with the demise of the walking city in the late 19th century. Holding agent preferences constant, but allowing the landscape of the Schelling model to evolve in ways that reflect historical changes to the built environment produces changes to the social landscape that are also consistent with history. Our work suggests that changes in residential segregation do not necessarily imply changes to individual attitudes and preferences. Changes in residential segregation can be generated by changes to the built environment, specifically the geographic distribution of housing. PMID:25419167

    The creation of the Veterinary Schools in the 18th century would reveal a plethora of scientists, some of whom would be the precursors of Pasteur, some rivals, others followers collaborators or friends of the Master. Among the precursors let us name Chabbert, Huzard, Girard, Delafond, Renault, Toussaint, Galtier ; among the rivals: Chauveau, Arloing, Cornevin and Thomas; among the followers, collaborators or friends of Pasteur: Bouley, at first a resolute spontaneist, then the most fervent in defense of Pasteur (President of the Academy of Medicine and of the Academy of Sciences) and Nocard, Director of the School in Alfort, an important collaborator of Pasteur. Later, there was Leclainche, who created the International Office of Epizootics, and who was President of the Academy of Sciences; Guérin, who with Calmette developed the BCG vaccination; Ramon, the father of anatoxins (vaccines against diphtheria, and tetanus, combined vaccines, adjuvants to immunity). Thus, the creation of the Veterinary Schools contributed not only to the evolution of the notion of contagion, to the amelioration of animal health and the economics of agricultural production, but also to serious advances in human care, and to the protection of public health.

    General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with discrepancies of up to 11°C for sea surface temperature estimates and 17°C for surface air temperature estimates. Sea ice has a strong influence on high-latitude climates, partly due to the albedo feedback. We present results demonstrating the effects of reductions in minimum sea ice albedo limits in general circulation model simulations of the mPWP. While mean annual surface air temperature increases of up to 6°C are observed in the Arctic, the maximum decrease in model-data discrepancies is just 0.81°C. Mean annual sea surface temperatures increase by up to 2°C, with a maximum model-data discrepancy improvement of 1.31°C. It is also suggested that the simulation of observed 21st century sea ice decline could be influenced by the adjustment of the sea ice albedo parameterization.

    The first laboratories of psychology established in Brazil were organized in the early twentieth century by professionals trained in medical schools or in education. These laboratories, linked to mental health hospitals or to normal schools, followed guidelines suggested by Edouard Claparède, from the Laboratory of Psychology of the University of Geneva, and by Alfred Binet, from the Laboratory of Psychology of the University of Paris (Sorbonne). Besides replicating experimental studies done in Europe, their purpose was to study the psychological characteristics of the population attended by the mental health or educational systems. The themes explored by the researchers were the comparison of psychological processes in normal and mentally troubled individuals, or the study of the mental development of school-age children. The meaning of the word "laboratory" became associated with applied psychology, and with the adaptation to the Brazilian population of mental tests elaborated in other countries (mainly in France). Around the 1940s and 1950s, with the establishment of the teaching of psychology in higher learning institutions, research in the area expanded. Two authors are mainly responsible for this expansion: Lourenço Filho (1897-1970), and Helena Antipoff (1892-1974). Their work, still inspired by Claparède and Binet, contributed to the development of important lines of research in psychology in Brazil, with a lasting influence on subsequent generations of psychologists. From the 1960s onwards, with the regulation of the profession of psychologist, formal university programs increased strongly, and, in the 1980s and 1990s, a comprehensive system of graduate programs in psychology was established, contributing to the professionalization of research in the field.

    2016-04-01

    Global ocean hindcast simulations for the period 1871-2009 have been run with the ocean-sea ice component of the Norwegian Earth System Model (NorESM-O), forced by an adjusted version of the Twentieth Century Reanalysis version 2 data set (20CRv2 data set), as well as by the commonly used second version of atmospheric forcing data set for the Coordinated Ocean-ice Reference Experiments phase-II (CORE-II) for the period 1948-2007 (hereafter CORE.v2 data set). The simulated Atlantic Meridional Overturning Circulation (AMOC) in the 20CR and the CORE simulations have comparable variability as well as mean strength during the last three decades of the integration. The simulated AMOC undergoes, however, distinctly different evolutions during the period 1948-1970, with a sharply declining strength in CORE but a gradual increase in 20CR. Sensitivity experiments suggest that differences in the wind forcing between CORE and 20CR have major impact on the simulated AMOCs during this period. It is furthermore found that differences in the air temperature between the two data sets do contribute to the differences in AMOC, but to a much lesser degree than the wind. An additional factor for the diverging AMOC in the two decades following 1948 is the inevitable switching of atmospheric forcing fields in 1948 in the CORE.v2-based runs due to the cyclic spin-up procedure of the ocean model. The latter is a fundamental issue for any ocean hindcast simulation. The ocean initial state mainly influence the actual value but to a lesser degree also the temporal evolution (variability) of AMOC. It may take about two decades for the AMOC to adjust to a new atmospheric state during the spin-up, although a dynamically balanced ocean initial state tends to reduce the adjustment time and the magnitude of the deviation, implying that an ocean model run with atmospheric forcing fields extending back in time, like 20CRv2, can be used to extend the reliable duration of CORE-type of simulations.

  18. Fram Strait ice export during the 19th and 20th centuries reconstructed from a multi-year sea-ice index from Southwestern Greenland

    2003-04-01

    Historical observations of multi-year ice, called 'Storis', in the Southwest Greenland waters exist from the period 1820-2000, obtained from ships logbooks and ice charts. It is argued that this ice originates in the Arctic Ocean and has travelled via the Fram Strait, southward along the Greenland coast in the East Greenland Current and around the southern tip of Greenland. Therefore, it is hypothesised that these observations can be used as 'proxies' for reconstructing the Fram Strait ice export on an annual basis. An index describing the Storis extent is extracted from the observations and a linear statistical model formulated relating this index to the Fram Strait ice export. The model is calibrated using ice export values from a hindcast study with a coupled ocean-ice model over the period 1949-1998. Subsequently, the model is used to reconstruct the Fram Strait annual ice export in the period 1820-2000. The model has significant skill, calculated on independent data. Based on this reconstruction, it is discussed how time periods with large and small ice export on multidecadal time scale coincide with time periods of cold and warm North Atlantic sea surface temperatures reported by others. This implies that trend studies based on satellite observations should be regarded with some care, since the time period of satellite observations, the last decades, where a particularly strong negative trend is observed in the ice export is preceded by a time period with a positive trend. The occurrence of 'Great salinity anomalies' (GSA's) are also connected to the multidecadal variability. The GSA's observed in Greenland waters around 1968-1970 and 1980-1982 both occurred when the general level of ice export was high. Prior to these there was a long period with generally low ice export and no GSA's but during an epoch around the turn of the 19th century several GSA's occurred. Finally, it is found that the correlation between the Fram Strait ice export and the NAO index

    Full Text Available The paper analyses the phenomenon of extramarital births in Serbia in the period of 1950-2008. Great changes that European countries have been undergoing in the last half-century related to fertility and family forms were also followed by an intense increase in the share of extramarital births. This is also true for Serbia (excluding Kosovo, where the share of extramarital births in total live births for the period of 1950-2008 increased almost 3 times (from 8.0% to 22.8%, and their number increased by a fifth (from 13,1 to 15,7 thousand. At the beginning of the observed period, significant differences existed in the percentage shares of extramarital births in the main regions, with the share in Vojvodina several times that of Central Serbia. Subsequent divergent dynamics led to the disappearance of regional differences and, after 1970, the level of extramarital fertility was mostly balanced. From a European aspect, the increase in the share of extramarital births in Serbia was moderate, with Serbia being one of the few countries that also recorded a decrease in the share of extramarital births in the last four decades (between 1970 and 1980. In comparison with other European countries, position of Serbia changed during the observed period from the top towards the bottom of the list, so that it was in its lower half in 2008. During the 1990s, as well as at the beginning of the 2000s, the greatest increase in the share of extramarital births in Europe was recorded in countries in transition. In the paper, the changes in the marital status of the population were treated as one of the determinants of the increase of extramarital births in Serbia. The paper also points out the similarities and differences between births in cohabitation and marriage, and legal aspects related to extramarital unions and extramarital births were also analyzed. The conclusions about the degree of presence of births in stable partner unions were made indirectly, based on

    Full Text Available Somalia has been one of the UN member countries who lingers from the presence of terrorist groups in its territory, that exert tremendous influence in the daily life of its society and economy. Al Shabaab is well known in the horn of Africa, particularly in Somalia, for its terrorist training and strong affiliation with other terrorist groups in Nigeria and Al-Qaeda. The Harakat Shabaab Al Mujahidin, also known as Al-Shabaab. has completely controlled the central and southern part of Somalia including some of its important sea ports, which are vital for the country’s economy. Although Ethiopian and Somali military forces attempted to rout the group in a two week war between December 2006 and January 2007, Al Shabaab, with its 14,500 militants, still continues to maintain control over strategic locations, not only in Somalia, but also throughout the horn of Africa. The paper delves into the recent events and attacks either undertaken or influenced by Al-Shabaab, including a snap shot of its threat to humanitarian aid personnel as well as the Africa Union troops who are desperately trying to lower the intensity of conflict along the Somalia Kenya border area and Al-Shabaab’s actions to secure financial resources.

    The American Eugenics Movement is a social movement launched and led by eugenicists from the early of the 20th century to 1940s in the name of eugenics .This movement focused on the propaganda to spread the knowledge of eugenics as well as on the making of eugenics laws and putting them into implementation .To be sure ,it was an active response of American eugenicists and their supporters to the social and demographic changes at the turning of the 20th century . However ,its philosophy and specific measures tended to be closely interwoven with racism ,nativism and other social prejudices ,which made the movement gradually become the tools of racial discrimination and social oppression .In the final analysis ,Eugenics Movement has not only made a lasting impact on American society ,but also provided a profound lesson in the history of science .%20世纪初至40年代的美国优生运动是一场在优生学名义下,由优生学家发起和领导的国内运动,其主要内容为宣扬优生知识、制定并实施优生立法。尽管这场运动是美国优生学家及其支持者们对19世纪末20世纪初美国社会及人口格局变化做出的积极回应,但它所宣扬的观念及其具体实践都融入了当时社会上所盛行的种族主义、排外主义以及其他偏见,使得这场运动逐渐沦为种族歧视和社会压迫的工具。时至今日,优生运动仍给美国社会带来了深远的影响,同时在科学发展史上留下了深刻的教训。

    Full Text Available Objective: to show the role played by experimental physiology in the way of understanding the effects of high-altitude climates on the functioning of the human body and the possibilities of progress of the Colombian nation throughout the 19th and early 20th centuries. Content: the transformation of the concept of climate as an object of scientific inquiry is explored over the studied period. This is done by analyzing investigations on respiratory capacity, nutrition and metabolism, blood chemistry and heart function in people of the eastern range of the Colombian Andes. Conclusions: beyond an institutional or disciplinary history of physiology, this article shows that some practices of experimental physiology played a role in the process of represent­ing the Colombian nation, territory, and population. The inhabitants of the Andean highlands were understood not only in terms of race and innate abilities, but also in terms of social classes and organic transformations. The idea that there was a supposed process of “physiological de­generation”, decreasing the efficiency of high-altitude workers, was tried to compensate through a “rational diet”.

    20世纪初,中韩知识分子都在国难当头、民族存亡之时发表了旧戏改良理论,两者的相同之处在于都具有功利主义的理论精神,都提出戏曲内容重于形式,都以西方文学思想为武器反对传统戏曲观。但相较而言,中国的旧戏改良理论所涉及的范围更加广泛,中国论者还亲手创作了许多剧本。因此,中国的旧戏改良比韩国取得了更为丰硕的成果。%In early 20th century, faced with national crises, intellectuals in China and Korea proposed theories of reforming old dramas. Those theories are similar in that they were all utilitarian and argued that the content of traditional dramas was more important than the form. They both used Western literature and thoughts as a weapon to oppose traditional views. However, relatively speaking, the Chinese reform theory is more wide-ranging, with supporters creating many plays by themselves. Therefore, the reform in China made more plentiful achievements.

    2015-06-01

    Full Text Available This article examines the role of the Russian government in the set-up of the spiritual life of Moslem communities. Between the second half of the 19th and early 20th centuries, the Russian government saw its major objective in control over communities practicing faiths other than Orthodox Christianity – most importantly, the activity of Moslem communities. Such policy, in large part, was about control over the construction of cult buildings, as well as the set-up of confessional schools. Based on archive materials, the author provides an insight into the issue of the set-up of the spiritual life of the Moslem community of Western Siberia during the period under examination, as well as the major aspects of record management in the area. Special attention is devoted to the complexity of getting permits for the erection of Moslem facilities, which sometimes led to unauthorized construction. There was a similar trend in respect of opening academic institutions, since the government mostly supported the creation of new-type schools with Russian-based classes and their major objective was teaching Russian and familiarizing Moslems with Russian culture.

    Women are the blind spots in China history of two thousand years, which makes "history" as a relative huge political concept for women. Thus, "history" or "historical narrative" is a writing topic for women to choose after they gain writing power which is significant for the modern Chinese women's writing.

    Using observations of sea surface temperature (SST) from HadISST and ERSST and the Coupled Model Intercomparison Project (CMIP) database in the 20th century, we analyzed the spatial variations in the long-term variation of SST over the tropical oceans in the twentieth century. The results displayed that the El Niño-Southern Oscillation (ENSO) and long term linear trend were the most significant signals, and this signal also displayed a long term linear trend. Observed Equatorial Indo-Pacific Sector SST exhibited a zonally asymmetric evolution:while the eastern part of the Equatorial Pacific showed only a weak warming, or even cooling in one SST dataset, the west-ern part and the Equatorial Indian Ocean exhibited a rather strong warming. The zonally asymmetric correlated the eastern part of the Equatorial Pacific significantly. These results may be important in the context of global warming, as regional climate changes in the Equatorial Sector may critically depend on inter-basin interactions.%利用 Hadley 中心海冰和海表面温度资料集 HadISST 和美国国家海洋大气管理局的扩展重建海温(ERSST)海表面温度(sea surface temperature, SST)观测数据,结合政府间气候变化专门委员会(Intergovernmental Panel on Climate Change, IPCC)中CMIP3(Coupled Model Intercomparison Project 3)的24个耦合模式的模拟结果,通过经验正交函数(EOF)分解等方法,对20世纪热带海洋在的SST年际变化进行了分析。结果表明,20世纪热带海洋年际变化的主要规律是ENSO信号,且有持续增强的趋势;热带海盆间存在显著的SST梯度,其长期变化与热带东太平洋显著相关。本文结论有利于理解在全球变暖背景下,海盆间的相互作用对赤道海域气候改变的影响。

Se ha pasado de una economía agraria de subsistencia a una economía competitiva de los servicios y del conocimiento, lo que ha supuesto enormes excedentes de mano de obra agraria hasta el final de siglo. Excedentes que fueron engrosando la intensa sangría emigratoria de los sesenta y setenta, que arrastró al 40% de la población regional. Sin embargo, desde comienzos de los ochenta, la población ha tendido a estabilizarse. Pero la emigración ya había provocado un estrangulamiento irreparable en las edades activas y de procreación, un fuerte descenso de la natalidad acentuado por la caída de la fecundidad posteriormente y un profundo envejecimiento. Por otra parte, la retención de los efectivos jóvenes y adultos en sus lugares de origen, junto a otros factores, incrementaron el paro hasta niveles desconocidos, si bien es un fenómeno que se ha conseguido paliar en buena medida en los últimos años del siglo. El futuro se presenta incierto, pues aunque no existe ningún núcleo abandonado, el envejecimiento, la baja natalidad y el paro están hipotecando el desarrollo endógeno de los núcleos rurales de la región.Summary: Along the second half of the 20th century the deepest transformations of the regional history have been produced so much by factors exogenous as endogenous of every kind.

    The development and impact of electromagnetism at the beginning of the 20th century are discussed from the angle of the “two theories and two discoveries”. The “two theories”refer to the electron theory of Lorentz and the electromagnetism theory of Einstein′s relativity, the so-called “two discoveries”are the discovery of the electron and the discovery of X-rays. The background, historical role and limitations of Lorentz′electron theory are first analyzed. Einstein′s revolutionary reform of classical electromagnetism is then discussed as well as several issues explained by electron theory. Some important experiments following the discovery of electron,and X-rays are also mentioned.%主要围绕电磁学的“两论两发现”讨论了上一世纪之交电磁学的发展和影响.“两论”是指洛伦兹电子论和爱因斯坦相对论电磁学,“两发现”是指X射线的发现和电子的发现.第一部分着重分析了洛伦兹电子论如何从综合超距电动力学和“无源”电磁场理论中产生的历史背景及其地位、作用和历史局限.第二部分重点讨论了爱因斯坦对经典电磁学的革命性变革、光量子假说、相对论电磁学和质能关系的意义及影响.第三和第四部分,则主要讨论X射线和电子的发现,及其发现后的电磁学的一些重要实验和电子论对一些重要电磁学问题的解释,强调了波粒二象性论争及其积极作用,并阐述了电子论对物质磁性的经典分析.文章的时间范围主要是从洛伦兹电子论到量子力学诞生之前的二三十年,尚未涉及量子电动力学的内容.

    National Amalgamation is always accompanied by the construction of culture. Books of Chinese culture and history in the early 20th century, attached more importance to the discussion on the relationship between integration and cultural construction. On the composition of the nationality and the culture, they emphasized the complexity of the Chinese nation and culture constitute and advocated that culture is not on the basis of race. On the national Amalgamation and cultural construction, they affirmed the centripetal force and assimilatory power of the Han nationality culture,emphasized the importance of integration for the cultural construction and believed that Chinese culture is a growing organism, not for the ethnic conflicts and regime changes and mutates. At the same time, they attached great importance to the impact of Indian culture and Western culture as the main foreign culture on Chinese culture.The se views are not only a new cognitive of national culture formed in the process of modern transformation of traditional historiography, but also the important embodiment of the modern nation-state ideas.%民族的融合始终伴随着文化的建构。在20世纪初的中国文化通史性著作中,颇为重视对民族融合与文化建构关系的讨论。在民族与文化的构成上,强调中国民族与文化构成的复杂性,主张“文化不以种族而分”。在民族融合与文化建构上,肯定中原汉族文化的向心力和同化力,强调民族融合对于文化建构的重要性,而且认为中国文化是一个不断发展的有机体,不因民族冲突和政权更迭而发生变异。同时十分重视以印度文化和西方文化为主的外来文化对中国文化的影响。这些观点既是传统史学近代转型过程中形成的民族文化新认知,同时也是近代民族国家观念的重要体现。

    The Later Memorial on Dispatching the Army, which has aroused a lot of controversy since the Qing Dynasty, is the most important material to study Zhuge Liang. The academic world holds different views on this issue. Some scholars think it is not Zhuge Liang's work, while the others approve its genuineness, and both sides provide much evidence for their argument. In this paper, the author collects, reviews and analyzes carefully the evidences from both the supporters and the opponents since the 20th century and finally comes to the conclusion that Zhuge Liang is indeed the author of the Later Memorial on Dispatching the Army based on the study of its origin, emotional tone, language use and historical figures concerned.%《后出师表》是研究诸葛亮的重要材料。自清代开始,《后出师表》的真伪成了学者们争论不休的话题。针对这一问题分别有正反两种观点。综合20世纪以来前人的研究成果,搜集关于证明《后出师表》真伪的各种依据。针对同一个论争点,学界分别有支持和反对两种观点。分别列出不同论争点的正反两种观点,总结陈述并细致分析这些观点。最后根据不同的论争点如《后出师表》的出处问题、感情基调与用语问题、涉及的历史人物等提出自己的观点,即《后出师表》确实出自诸葛亮之手。

    “范式”一词于20世纪70年代由库恩基于科学哲学提出,并逐渐为科学界接受。同时,各学科学者借用库恩的“范式”概念和“研究程序”思想而构建出本学科的研究范式。因此,使得各学科间的研究范式既具有相对独立性又存在联系性。地理学也因此形成自己的研究范式。中国近现代地理学作为世界地理学的重要组成部分,深受其思想与方法的影响。因此,系统地认识20世纪初叶以来我国地理学研究范式的发展历程十分必要。采用“历史”与“逻辑”统一的原则对地理学研究范式的含义与意义及我国地理学研究范式历史的认识进行研究得出:中国地理学经历了区域因果关系范式到空间范式的继承与转变;我国近现代地理学范式的发展始终是“显范式”(冠予“范式”一词的研究方法)与“潜范式”(未冠予“范式”一词的研究方法)并存发展的;我国人文地理学研究范式与应用多以“显范式”为主,自然地理学多以“潜范式”为主;所有地理学研究范式都遵循地理学空间思想指导;未来地理学研究范式将朝向定量化、技术化、空间化、社会性和文化性方向及格局、过程、机制及模拟发展,朝向科学第四范式迈进。%The word Paradigm, which was raised by Kuhn in the 1970s based on the philosophy of science,is accepted gradually by academic cicles.

Geography has it’s own paradigm specially. The modern geography in China is affected by the ideas and methods of that in the world. Therefore, it is necessary to understand systematically the history of the paradigm of Chinese geography in the 20th century. In this article, the history and logic are

    Sexuality has been defined a central feature of personal identity since the epoch of enlightenment and has gradually become a decisive issue also in societal and political terms. A major transfer from religion and religious institutions to medicine and medical experts and later on to neuropsychiatrists has to be underlined in the primary position to assess "normal" and "deviant" manifestations of sexuality. Richard Freiherr von Krafft-Ebing and Sigmund Freund play an eminent role in this "discourse on sexuality" (M. Foucault) during the nineteenth and beginning twentieth century on the way to modern sexology. Within this overarching context Krafft-Ebing's and Freud's theoretical conceptualizations of sexuality and perversion will be sketched and basic clinical and societal implications there out will be discussed.

    During late 19th to early 20th century, the monopolies within Russian petroleum industry form and achieve a rapid development. The factors such as establishment and popularization of joint-stock company, intense free contention among enterprises, penetration of foreign capital, and integra-tion of bank capital with industrial capital have jointly promoted an unprecedented centralization of production and capital within Russian petroleum industry, therefore provide necessary conditions for the formation of monopolies. During this period, petroleum monopoly of three types including Cartel, Syndicate and Trust is set up one after another and carries out activities of a wide range. They grab high monopoly profits by establishing monopoly price of petroleum and its products, strongly oppose state regulation of petroleum price, and actively participate in the competition of world petroleum mar-ket. These activities bring a dual effect that is both positive and negative to the development of Rus-sian petroleum industry; therefore, the two trends of outgrowth and stagnation coexist or alternate with each other within the production of petroleum industry.%19世纪末20世纪初,俄国石油工业垄断形成并获得快速发展。这主要是股份制公司的建立和推广、各企业之间激烈的自由竞争、外国资本的渗入及银行资本与工业资本的融合等因素,共同促进了俄国石油工业中生产和资本的空前集中,为垄断的形成提供了必要条件。在这一时期,卡特尔、辛迪加和托拉斯三种类型石油垄断组织先后建立并开展了广泛的活动,即通过建立石油及其产品的垄断价格攫取高额垄断利润;极力反对国家调控石油价格;积极参与争夺世界石油市场。这些活动给俄国石油工业的发展带来了双重影响,既有正面的促进作用,也有负面的抑制作用,从而使石油工业生产呈现出发展与停滞两种趋势同时并存、相互交替的局面。

    Full Text Available The article presents statistical data on the publications of belles-lettres in Estonia in 1900–1940 – a period when the country developed into a modern European society and gained independence. The topic is treated in the context of book history, which uses publishing statistics to provide a broader context for individual case studies. The research on the quantity and share of translated literature in book production comes close to the statisticalsociological approach in translation history, characterised by Peeter Torop as one of the aspects of the study of translation culture. The statistical indicators have been elaborated on the basis of retrospective bibliographies and on the data, obtained from National Library of Estonia. The analysis includes the share of belles-lettres in book production, the balance of original works and translations, the changes in the quantity of translations during different decades and the share of source literatures. The Estonian statistics have been presented in comparison with corresponding data from Finland, which has been published in the collective monograph on Finnish translation history, issued in 2007. As the Finnish data is organized by decades, the same principle is used for statistics on Estonia. This approach corresponds generally to the political history of the two countries – both belonged to the Russian Empire during the first two decades of the 20th century and existed as independent states during the following two decades. Both nations had passed through the first stage in the development of literary culture, characterised by extensive publication of adaptations and free translations by the beginning of the century. Thus the share of original works started to increase and slightly exceeded the share  of  translations  in  E stonia  as  well  as  in  Finland.  The  selection  of  translated  works  in both countries was varied and their level was unstable.

    Full Text Available Until recently, the treatment of Estonian literature from the beginning of the 20th century has been influenced by the literary and cultural activities and programmatic articles of the Young Estonia movement. Current research on Young Estonia has addressed their more everyday realm of activity, which has heretofore received less attention: the Young Estonians as readers of the new works of their literary contemporaries and their practical criticism in reviews, particularly in daily newspapers. This article uses a receptionhistorical approach to analyze a large body of source material: the Young Estonians voluminous critical oeuvre in the period 1905–1915. The Young Estonians to be examined are all members of the core group of the movement: Gustav Suits, Bernhard Linde, Aino Kallas, Johannes Aavik, Villem Grünthal-Ridala, Jaan Oks, August Alle, and Johannes Semper. Within the larger framework of collective horizons of expectation, the focus of the study is the critics` concept of the reader. In addition, I will briefly discuss the dynamics of how such conceptions change. Research results indicate that in critical reviews from the time of Young Estonia, the topic of the reader was addressed from different standpoints depending on the addressee. Texts directed rhetorically toward a broad readership are characterized by the pursuit of objectivity and generalizations. When the concept of the reader is critic-centered, the text emphasizes subjective judgments, experience, and emotion. When focusing on the author and the text, the reviewer describes the influence on the reader, the cause of which is either the literary work directly or the author’s genius. In the case of polemic on the subject of reading, found mainly in responses written to reviews, the writer interprets another reader (or other readers` reading, opposing it to his or her own. When we follow the way the readers of Young Estonia and the Young Estonians themselves handle the

Frauen in den Wissenschaften waren in der Weimarer Republik fast schon selbstverständlich, als der Nationalsozialismus zu gravierenden Rückschlägen führte. Damit einher ging die Verschiebung des universitären Betätigungsfeldes der Frauen von den Natur- zu den Geisteswissenschaften. Noch lange nach 1945 waren die Folgen dieser Entwicklung zu spüren. Zu diesen Ergebnissen kommt Vogt durch die vergleichende Analyse der Werdegänge von mehreren hundert Wissenschaftlerinnen an der Berliner Universität und der außeruniversitären Kaiser-Wilhelm-Gesellschaft in der ersten Hälfte des 20. Jahrhunderts.“From the exception to the marginalized": Thus reads Annette Vogt’s summary for the first fifty years in which German universities opened their doors to women. During the Weimar Republic the existence of women in the sciences went almost without saying, until National Socialism led to grave setbacks. Along with this came the displacement of women working in the university from the area of the natural sciences to that of the humanities. The consequences of this development were felt long after 1945. Vogt comes to these conclusions through a comparative analysis of the career development of hundreds of female scientists at Berlin universities and at the Kaiser-Wilhelm-Society in the first half of the 20th century”.

    Still, Tamara G.

    Paul Fritts is known internationally as a builder of mechanical-action pipe organs based on historical models of the 17th and 18 th centuries. He is one of a number of contemporary builders who have researched renaissance and baroque organs as a point of departure for their designs. As builders have returned to antique models to inform their craft, they have debated the importance of certain aspects of classical design. Included here is discussion of some aspects of design with regard to Fritts and other important mechanical-action organbuilders. Topics of discussion include the significance of pipe metals, temperaments and tunings, key action and case design. Some of the professional debate is scientific, other is subjective and very emotional. This dissertation explores the work of Paul Fritts and chronicles his contribution.

This article concludes with a provisional assessment of a cultural confrontation.

    Full Text Available La obra artística de Violeta Parra presenta, en diversos niveles, una compleja problematización de los esquemas sociales de la primera mitad del siglo XX. Este trabajo busca examinar los modos en los que esta folclorista transita por los esquemas de género que recaían sobre los hombres y mujeres de la época, dando lugar a una mirada crítica e irreverente en la que la tradición cultural y la innovación confluyen, tanto en lo que respecta al contenido de sus textos como en el plano expresivo de su musicalidad.Violeta Parra's artistic work presents on different levels the complex problem of unraveling the social schemes of the first half of the twentieth century. This article examines the ways in which this "folclorista" moved through the gender schemes corresponding to men and women of that epoch. This movement opened a space for a both critical and irreverent view in which cultural tradition and innovation converge, both regarding the contents other texts as well as the expression of their musicality.

    Full Text Available En los albores de la pasada centuria, la difusión de la figura de Mefistófeles, concebida como evolución moderna de la imagen de Satanás, fue un fenómeno social y cultural de suma importancia en cuanto a lo que atañe a la divulgación de la fe cristiana entre el imaginario colectivo. En España, la prensa se nutrió del terror de la Gran Guerra para relegar al Diablo de su trono del Mal, haciendo de él un individuo cuyas artes se amoldaban a la era moderna, y dejando, por consiguiente, su halo maléfico al ser humano. Con todo, ya desde el ocaso del período decimonónico y el « esplendor » de la Belle Époque, así como durante la década de los años veinte y la Segunda República, la literaturización que se hizo del Maligno revolucionó las mentalidades burguesas y populares de la época, dado que los periódicos estaban mucho más cerca de la realidad cotidiana de la gente que la propia Iglesia. De este modo, la prensa logró que hombres y mujeres perdieran el temor al Satanás difundido por la dogmática cristiana y, simpatizaran con un Mefistófeles que comprendía mucho mejor las desdichas y las alegrías de sus vidas.At the dawn of the past century, the diffusion of the character of Mephistopheles, conceived as the modern evolution of the image of Satan, was an extraordinarily important social and cultural phenomenon from the perspective of spreading the Christian faith within the collective imaginary. In Spain, the press was fuelled by the terror of the Great War to drive the Devil from his throne of evil, thus turning him into an individual whose arts adjusted to the modern period and leaving his evil halo to the human being. All the same, as early as the decline of the nineteenth century and the height of the Belle Époque, and during the twenties and the Spanish Second Republic, the literaturisation that was made of the devil revolutionised the ideas of the Bourgeoisie and the people of the time since newspapers were much

    Full Text Available ResumenLejos de ser un concepto de índole técnica —el simple equilibrio higrotérmico entre las condiciones del clima y las constantes fisiológicas humanas— el confort es una idea culturalmente construida, que concierne a factores heteróclitos, como la relación de la arquitectura con el cuerpo, o el modo en que se conciben a través de este la naturaleza, el espacio y la materialidad. Sin embargo, la noción de confort no ha merecido toda la atención historiográfica que merece, de ahí la necesidad de una nueva perspectiva de índole estética y multidisciplinar. Tal punto de vista se ensaya en el artículo a través de una parcial y brevísima historia del confort que recoge los diferentes sentidos asignados al concepto a lo largo de los dos últimos siglos de acuerdo a una suerte de ‘poéticas’: la añeja poética del fuego, vinculada al confort regenerativo; las poéticas de la higiene y del hábitat, desarrolladas durante la modernidad como dogmas cientificistas y a la vez como coartadas estéticas, y, finalmente, la poética de las atmósferas, que da cuenta de las inquietudes contemporáneas sobre la percepción, la memoria y la sociabilidad. De tal repaso histórico puede concluirse que el bienestar no es un concepto objetivable ni aislable en la probeta del técnico o el científico, sino una noción compleja, formada por capas diversas que se entremezclan: fisiológicas, constructivas, estéticas, existenciales, sociales. La historia del confort es, de este modo, una suerte de versión reducida de la historia de la cultura.Palabras claveconfort, arquitectura, higiene, hábitat, atmósferaAbstractArchitectural history of the last two centuries shows that welfare, far from being a purely technical issue – a balance between weather and the physiological human constants – is a culturally constructed idea concerning diverse factors, such as the relationship between space and human body or the ways of conceiving nature in

Maintenant, c’est le conflit ouvert, la guerre, qui l’emporte. D’un autre côté, nombreux sont les auteurs inspirés par la religion musulmane, voire le soufisme, ce qui constitue en fait une influence ottomane détournée.The Ottoman Empire, whose occupation in Bosnia lasted from the 15th to the 19th century, left numerous traces in local literature. A big number of Slavs, who converted to Islam, wrote their literary works in so-called oriental languages (Turkish, Arabic and Persian; their poetry anthologies, dîwâns, written in Ottoman Turkish, were impregnated by Sufism (Muslim mysticism. There are hundreds of authors of this kind, a phenomenon specific to Bosnia and not found among all the other countries occupied by the Ottomans. We observe a double identity in Bosnian Ottoman poems: both an attachment to the Empire, due to the Muslim religion, as well as to their country or town. Numerous authors also expressed themselves in the Slavic Bosnian language, by using Arabic characters (a kind of literature known by the name of alhamiado or aljemiado; another type, principally an urban one, the sevdalinka is representative of Muslim popular art, still very famous these days in the Balkans.Among the Bosnians who wrote in the Bosnian language by using latten characters--this movement appeared at the end of the 19th century--it is necessary to mention Safvet Bey Bašagić (1870-1934 and Musa

    1974-01-01

    Wind turbine systems for generating electrical power have been tested in many countries. Representative examples of turbines which have produced from 100 to 1250 kW are described. The advantages of wind energy consist of its being a nondepleting, nonpolluting, and free fuel source. Its disadvantages relate to the variability of wind and the high installation cost per kilowatt of capacity of wind turbines when compared to other methods of electric-power generation. High fuel costs and potential resource scarcity have led to a five-year joint NASA-NSF program to study wind energy. The program will study wind energy conversion and storage systems with respect to cost effectiveness, and will attempt to estimate national wind-energy potential and develop techniques for generator site selection. The studies concern a small-systems (50-250 kW) project, a megawatt-systems (500-3000 kW) project, supporting research and technology, and energy storage. Preliminary economic analyses indicate that wind-energy conversion can be competitive in high-average-wind areas.

    Malaria has been part of Peruvian life since at least the 1500s. While Peru gave the world quinine, one of the first treatments for malaria, its history is pockmarked with endemic malaria and occasional epidemics. In this review, major increases in Peruvian malaria incidence over the past hundred years are described, as well as the human factors that have facilitated these events, and concerted private and governmental efforts to control malaria. Political support for malaria control has varied and unexpected events like vector and parasite resistance have adversely impacted morbidity and mortality. Though the ready availability of novel insecticides like DDT and efficacious medications reduced malaria to very low levels for a decade after the post eradication era, malaria reemerged as an important modern day challenge to Peruvian public health. Its reemergence sparked collaboration between domestic and international partners towards the elimination of malaria in Peru.

Based on specialists' statements as well as opinions from educational reformers and journalists it is clear that this exclusion was created due to the stigmatization of the social places belonging to the poor children through the image of the urchins and street boys.. Such images were a model that could reveal the illegitimacy of the family structures, of the school history and of the way children from the popular areas lived, given the articulation, mistaken and dangerous, that was established between the life of poor people and children delinquency.

    Full Text Available Este estudo analisa o comportamento epidemiológico da doença meningocócica na cidade de São Paulo, Brasil, ao longo do século XX. Utilizando dados de prontuários, atestados de óbito e do sistema de vigilância epidemiológica os autores descrevem a tendência secular da doença, sua variação sazonal, a distribuição espacial e por idade e sexo. A tendência secular mostra incidência constante nos períodos endêmicos, interrompida pela presença de epidemias. As quatro epidemias registradas durante o século XX ocorreram em momentos de graves perturbações sociais e foram produzidas pelos sorogrupos A, A e C, e B e C. A variação sazonal com exacerbação no outono/inverno mantém-se constante durante todo o século. A distribuição espacial acompanha os deslocamentos da população pobre no espaço urbano. A distribuição por idade e sexo mantém-se inalterada em todos os períodos endêmicos, mostrando maior risco entre os menores de um ano e decréscimos acentuados à proporção que aumenta a idade. Os períodos epidêmicos, com exceção do último, mostram alteração significante na distribuição etária, com aumento do risco entre jovens e adultos jovens, e ocorrência de casos em todas as faixas etárias.This study analyzes the epidemiological behavior of meningococcal disease in the city of São Paulo, Brazil, over the course of the 20th century. Applying data from patient records, death certificates, and epidemiological surveillance, the authors describe trends in the disease throughout the century, seasonal variations, and incidence distribution by area, age, and gender. The temporal trends show constant incidence during endemic periods, interrupted by epidemic events. Four epidemic events during the last century occurred in circumstances of serious social disturbances and were caused by serogroups A (the first two, A and C, and B and C, respectively. Seasonal variations involved aggravation during autumn and winter

    Full Text Available Les représentations de la Passion et de la Vie de Jésus ont figuré parmi les premiers titres des débuts du cinéma. A posteriori, la critique des films religieux, notamment dans les années soixante, a été sévère pour ces tentatives jugées plus commerciales que très inspirées. L’intérêt pour le cinéma des premiers temps s’est approfondi dans les dernières décennies et favorise une autre approche de ces productions des années 1895-1920. Restituer l’univers visuel dans lequel ces films ont pris naissance permet de préciser les modalités de représentation des sujets biblique, en lien avec l’historicisme et l’orientalisme. Outre les liens étroits avec la peinture et la photographie, ces premiers films retrouvent certains effets narratifs des jeux de la Passion ou des projections d’images fixes encore abondantes au tournant du XXe siècle. S’attacher à la conception de la figuration contribue à cerner le « désir de voir » et l’effet de présence christique qui se manifestent dans ces premières Passion filmées.Representations of the Passion and the Life of Jesus Christ were a popular topic in early cinema. Retrospective criticism, especially in the 1960’s, was judgmental towards the first religious films, insofar as they were regarded more as commercially driven reenactments than inspired works. Interest in early cinema deepened in recent decades, and has led to a different reading of productions from the period 1895-1920. By restoring the universe of visual references in which these films arose, we are able to relate representations of biblical subjects to movements in historicism and Orientalism. Beyond their close relationship with painting and photography, these early films also reproduced the narrative effects of Passion plays or projections of fixed images that were still widespread at the turn of the 20th century. A focus on figurative conception will help us reconnect with the "need to see" and

    "JiaoXue" is the most central concept in teaching theory.The study on the changes of the concepts of "JiaoXue" in the textbooks of teaching theory will help us understand the changes of the general teaching thinking.From the early 20th century to the 1960s,the mainstream understanding of the concept in China had been influenced successively by Japan which was affected by Herbart's theory,the behavioral psychology of the United States,and the pedagogy of the Soviet Union.After 1980s,our understanding of the concept has formed Chinese characteristics,generally considering it as the unity of teaching and learning in education activities.The statement to educational teaching in different periods' concepts of "JiaoXue" has reflected that the concepts are generally not the description of reality,but the expression of some ideal standards.These kinds of concepts have an important function in leading the teaching practice.%"教学"是教学理论中最为核心的概念,对不同时期教学论教材中的教学概念变迁的研究,有利于我们认识主流教学观念的变化。20世纪初至20世纪60年代,我国对教学概念的主流认识相继受到日本具有赫尔巴特学派倾向的教学理论、美国行为主义心理学、苏联教育学和教学论的影响。80年代后,我国对教学概念的认识形成了中国特色,普遍认为教学是教与学相统一的教育活动。不同时期的教学概念对"教学的教育性"问题的表述,反映了教学概念通常不是对客观存在的教学的描述,而是对应然教学的一种规范。这种规范性的教学概念对教学实践具有重要的引领功能。

    Full Text Available O artigo discute o processo de introdução da energia elétrica na cidade de São Paulo no início do século XX. A Proclamação da República marcou o início da modernização das empresas de serviços urbanos, com a introdução da eletricidade. Foi neste contexto que dois grupos iniciaram uma intensa batalha no setor elétrico paulista: o grupo nacional da Companhia Brasileira de Energia Elétrica (CBEE - conhecido também como Docas de Santos - e o canadense Light. A falta de uma legislação federal para o setor de energia elétrica legou às Câmaras Municipais o poder concedente para os serviços de eletricidade, garantindo que as relações políticas entre vereadores e empresários tivessem decisivo papel na instalação de tais serviços. Assim, o artigo descreve o processo de introdução da eletricidade em São Paulo mediante os debates sobre a regulamentação dos serviços públicos, desvendando os critérios políticos ou ideológicos que levaram a conformação de tais leis.This paper discusses the introduction of electric power in the city of São Paulo during the beginning of the 20th century. The Brazilian Republic Proclamation (1889 established the beginning of the public services companies' modernization, which through the enterprises fusion and the arrival of foreign capital allowed the electric power introduction in the main Brazilian cities. Two rival groups started a competition in the São Paulo's electric sector: the national enterprise Companhia Brasileira de Energia Elétrica (CBEE - so called as Docas de Santos - and the Canadian company Light. The inexistence of a federal legislation to electric power services had transformed municipal decisions in deterministic guidelines for utility bids, making municipal lobbying a key instrument in utility concessions. Hence, this paper issues describe the electric power introduction in the city through the debates about the utilities' rules, analyzing the political or

    In the 20th century,scientists has played an important role in U.S.nuclear weapons policy,and once as representatives participate in political negotiations.Through this process,U.S.nuclear scientists are involved into the realm of politics.In political affairs,they use their own expertise,sometimes occupying a dominant position.These scientists have affected the formulation of national policy,and political decision-making activities,in turn,have profoundly influenced the development of scientists' career.After Cold War,U.S.scientists participate in the development of nuclear power,and economic factors and cultural factors such as nuclear safety directly affect the operations of nuclear power plants and technical safety,thereby affecting the professional behaviors of the nuclear scientists.The scientists showed the tendency of the diverse pursuits such as interest,fame and gain as well as diverse social responsibility and moral understanding.The diversity of the scientist's role in society has become increasingly evident.%20世纪的科学家在美国的核武政策中发挥了重要作用,一度作为代表参加政治谈判。美国的核科学家们通过这一过程被纳入到政治范畴。在政治斗争中,他们也会利用自身的专门知识占据优势地位。这些科学家影响了国家政策的制定,反过来,政治决策活动也深刻地影响了科学家的职业发展。冷战后,美国科学家参与到核电发展之中,经济因素与核安全文化因素直接影响核电公司的运行与技术操作,进而影响到核电科学家的职业行为。科学家表现出追求功利以及社会责任与道德认识多元化等倾向。科学家的社会角色的多元性日趋明显。

    Full Text Available A melhora das condições de vida do homem durante o século XX contribuiu para transformações da estrutura demográfica e para mudanças dos padrões de morbi-mortalidade. Com o objetivo de discutir essas mudanças, pretende-se comparar os dados de mortalidade do Município de São Paulo em 1901, 1960 e 2000. As causas de morte foram obtidas das seguintes fontes: Anuários Estatísticos da FSEADE, para 1901; Anuário de 1961 do Departamento de Estatística do Estado e CD-ROM de Mortalidade do Ministério da Saúde, para o ano de 2000. Os demais dados - de população, de nascidos vivos, coeficientes de mortalidade geral e infantil - foram obtidos do CD-ROM "500 anos de Divisão territorial e 100 anos de Estatísticas Demográficas Municipais" da FSEADE. Do início até o final do século XX, a população do Município de São Paulo aumentou 36 vezes, o número de nascimentos quase 24 e o número de óbitos 13,6 vezes. No entanto, as taxas de mortalidade diminuíram, a mortalidade geral foi 2,6 vezes menor no ano 2000 e a mortalidade infantil 11,3 vezes menor. A proporção de óbitos por doenças infecciosas declina de 45,7% do total de óbitos em 1901 para 9,7% em 2000. Em 1901, entre as 10 principais causas de morte no Município, 5 eram doenças infecciosas, correspondendo a 37% das mortes; em 1960, apareciam nesta lista apenas 3 doenças infecciosas (16,1% dos óbitos, e em 2000 apenas a pneumonia constava entre as principais causas de morte. Doenças como tétano, difteria, coqueluche, sarampo e escarlatina mostraram-se controladas no final do período. No entanto, a pneumonia, a tuberculose, a septicemia e a aids ainda se situam entre as que merecem especial atenção na área de saúde pública.The changes in living conditions during the 20th century have contributed to change morbidity and mortality standards, and the population structure. This study aims to present and discuss these changes by comparing mortality data of the City of
