Sample records for twentieth century sea

  1. Probabilistic reanalysis of twentieth-century sea-level rise. (United States)

    Hay, Carling C; Morrow, Eric; Kopp, Robert E; Mitrovica, Jerry X


    Estimating and accounting for twentieth-century global mean sea level (GMSL) rise is critical to characterizing current and future human-induced sea-level change. Several previous analyses of tide gauge records--employing different methods to accommodate the spatial sparsity and temporal incompleteness of the data and to constrain the geometry of long-term sea-level change--have concluded that GMSL rose over the twentieth century at a mean rate of 1.6 to 1.9 millimetres per year. Efforts to account for this rate by summing estimates of individual contributions from glacier and ice-sheet mass loss, ocean thermal expansion, and changes in land water storage fall significantly short in the period before 1990. The failure to close the budget of GMSL during this period has led to suggestions that several contributions may have been systematically underestimated. However, the extent to which the limitations of tide gauge analyses have affected estimates of the GMSL rate of change is unclear. Here we revisit estimates of twentieth-century GMSL rise using probabilistic techniques and find a rate of GMSL rise from 1901 to 1990 of 1.2 ± 0.2 millimetres per year (90% confidence interval). Based on individual contributions tabulated in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, this estimate closes the twentieth-century sea-level budget. Our analysis, which combines tide gauge records with physics-based and model-derived geometries of the various contributing signals, also indicates that GMSL rose at a rate of 3.0 ± 0.7 millimetres per year between 1993 and 2010, consistent with prior estimates from tide gauge records.The increase in rate relative to the 1901-90 trend is accordingly larger than previously thought; this revision may affect some projections of future sea-level rise.

    The prediction of global sea-level rise is one of the major challenges of climate science. While process-based models are still being improved to capture the complexity of the processes involved, semi-empirical models, exploiting the observed connection between global-mean sea level and global temperature and calibrated with data, have been developed as a complementary approach. Here we investigate whether twentieth century sea-level rise could have been predicted with such models given a knowledge of twentieth century global temperature increase. We find that either proxy or early tide gauge data do not hold enough information to constrain the model parameters well. However, in combination, the use of proxy and tide gauge sea-level data up to 1900 AD allows a good prediction of twentieth century sea-level rise, despite this rise being well outside the rates experienced in previous centuries during the calibration period of the model. The 90% confidence range for the linear twentieth century rise predicted by the semi-empirical model is 13–30 cm, whereas the observed interval (using two tide gauge data sets) is 14–26 cm. (letter)

  3. Experiments in Reconstructing Twentieth-Century Sea Levels (United States)

    Ray, Richard D.; Douglas, Bruce C.


    One approach to reconstructing historical sea level from the relatively sparse tide-gauge network is to employ Empirical Orthogonal Functions (EOFs) as interpolatory spatial basis functions. The EOFs are determined from independent global data, generally sea-surface heights from either satellite altimetry or a numerical ocean model. The problem is revisited here for sea level since 1900. A new approach to handling the tide-gauge datum problem by direct solution offers possible advantages over the method of integrating sea-level differences, with the potential of eventually adjusting datums into the global terrestrial reference frame. The resulting time series of global mean sea levels appears fairly insensitive to the adopted set of EOFs. In contrast, charts of regional sea level anomalies and trends are very sensitive to the adopted set of EOFs, especially for the sparser network of gauges in the early 20th century. The reconstructions appear especially suspect before 1950 in the tropical Pacific. While this limits some applications of the sea-level reconstructions, the sensitivity does appear adequately captured by formal uncertainties. All our solutions show regional trends over the past five decades to be fairly uniform throughout the global ocean, in contrast to trends observed over the shorter altimeter era. Consistent with several previous estimates, the global sea-level rise since 1900 is 1.70 +/- 0.26 mm/yr. The global trend since 1995 exceeds 3 mm/yr which is consistent with altimeter measurements, but this large trend was possibly also reached between 1935 and 1950.

  4. Twentieth-century global-mean sea level rise: Is the whole greater than the sum of the parts? (United States)

    Gregory, J.M.; White, N.J.; Church, J.A.; Bierkens, M.F.P.; Box, J.E.; Van den Broeke, M.R.; Cogley, J.G.; Fettweis, X.; Hanna, E.; Huybrechts, P.; Konikow, Leonard F.; Leclercq, P.W.; Marzeion, B.; Oerlemans, J.; Tamisiea, M.E.; Wada, Y.; Wake, L.M.; Van de Wal, R.S.W.


    Confidence in projections of global-mean sea level rise (GMSLR) depends on an ability to account for GMSLR during the twentieth century. There are contributions from ocean thermal expansion, mass loss from glaciers and ice sheets, groundwater extraction, and reservoir impoundment. Progress has been made toward solving the “enigma” of twentieth-century GMSLR, which is that the observed GMSLR has previously been found to exceed the sum of estimated contributions, especially for the earlier decades. The authors propose the following: thermal expansion simulated by climate models may previously have been underestimated because of their not including volcanic forcing in their control state; the rate of glacier mass loss was larger than previously estimated and was not smaller in the first half than in the second half of the century; the Greenland ice sheet could have made a positive contribution throughout the century; and groundwater depletion and reservoir impoundment, which are of opposite sign, may have been approximately equal in magnitude. It is possible to reconstruct the time series of GMSLR from the quantified contributions, apart from a constant residual term, which is small enough to be explained as a long-term contribution from the Antarctic ice sheet. The reconstructions account for the observation that the rate of GMSLR was not much larger during the last 50 years than during the twentieth century as a whole, despite the increasing anthropogenic forcing. Semiempirical methods for projecting GMSLR depend on the existence of a relationship between global climate change and the rate of GMSLR, but the implication of the authors' closure of the budget is that such a relationship is weak or absent during the twentieth century.

  5. Aerosol-driven increase in Arctic sea ice over the middle of the twentieth century (United States)

    Gagné, Marie-Ève; Fyfe, John C.; Gillett, Nathan P.; Polyakov, Igor V.; Flato, Gregory M.


    Updated observational data sets without climatological infilling show that there was an increase in sea ice concentration in the eastern Arctic between 1950 and 1975, contrary to earlier climatology infilled observational data sets that show weak interannual variations during that time period. We here present climate model simulations showing that this observed sea ice concentration increase was primarily a consequence of cooling induced by increasing anthropogenic aerosols and natural forcing. Indeed, sulphur dioxide emissions, which lead to the formation of sulphate aerosols, peaked around 1980 causing a sharp increase in the burden of sulphate between the 1950s and 1970s; but since 1980, the burden has dropped. Our climate model simulations show that the cooling contribution of aerosols offset the warming effect of increasing greenhouse gases over the midtwentieth century resulting in the expansion of the Arctic sea ice cover. These results challenge the perception that Arctic sea ice extent was unperturbed by human influence until the 1970s, suggesting instead that it exhibited earlier forced multidecadal variations, with implications for our understanding of impacts and adaptation in human and natural Arctic systems.

  6. The Diversity of Cloud Responses to Twentieth-Century Sea Surface Temperatures (United States)

    Silvers, L. G.; Paynter, D.; Zhao, M.


    Clouds play a crucial role in determining the magnitude of the global temperature response to forcing. Previous work has shown strong connections between cloud feedbacks and climate change, and between these feedbacks and changing patterns of surface temperature. We show that strong variability of the climate feedback parameter is present in three GFDL atmospheric general circulation models (AM2.1, AM3, AM4) over the twentieth century. This variability is highly correlated with the global mean cloud radiative effect (CRE) and low-cloud cover (LCC) anomalies. The decadal variability is characterized by a period of high climate sensitivity (1925-1955) and a period of low climate sensitivity (1975-2005). Observed trends of surface temperature also show distinct differences over these two periods. Although it is the SST that drives the atmospheric response, the estimated inversion strength (EIS) is necessary to reproduce the changing LCC field. During both periods, trends of EIS are shown to closely mirror trends of LCC over much of the globe, not only in the typical stratocumulus regions. Trends of the shortwave CRE (SWCRE), LCC, and the EIS are analyzed in particular geographic regions. All of these regions show a consistent relationship between LCC, SWCRE, and EIS, as well as significant differences between the two time periods. This study uses a 15 member ensemble of amip-piForcing simulations from 1870 -2005. These experiments are driven by observed SST patterns and hold greenhouse gases and other atmospheric forcing agents fixed at constant pre-industrial levels. This allows for a clean analysis of how clouds respond to changing patterns of SST and the resulting influence on the climate feedback parameter. The cloudy response of the atmosphere to changing SST patterns is critical in driving the variability of the climate feedback parameter during periods of both high and low climate sensitivity.

  7. The Diversity of Cloud Responses to Twentieth Century Sea Surface Temperatures (United States)

    Silvers, Levi G.; Paynter, David; Zhao, Ming


    Low-level clouds are shown to be the conduit between the observed sea surface temperatures (SST) and large decadal fluctuations of the top of the atmosphere radiative imbalance. The influence of low-level clouds on the climate feedback is shown for global mean time series as well as particular geographic regions. The changes of clouds are found to be important for a midcentury period of high sensitivity and a late century period of low sensitivity. These conclusions are drawn from analysis of amip-piForcing simulations using three atmospheric general circulation models (AM2.1, AM3, and AM4.0). All three models confirm the importance of the relationship between the global climate sensitivity and the eastern Pacific trends of SST and low-level clouds. However, this work argues that the variability of the climate feedback parameter is not driven by stratocumulus-dominated regions in the eastern ocean basins, but rather by the cloudy response in the rest of the tropics.

    The revolution in twentieth century physics has changed the way we think about space, time and matter and our own place in the universe. It has offered answers to many of the big questions of existence, such as the ultimate nature of things and the how the universe came into being. It has undermined our belief in a Newtonian mechanistic universe and a deterministic future, posing questions about parallel universes, time-travel and the origin and end of everything. At the same time we have witnessed amazing attempts at unification so that physicists are able to contemplate the discovery of a si

  9. The sea as science: ocean research institutions and strategies in Portugal in the twentieth century (from the First Republic to democracy). (United States)

    Rollo, Maria Fernanda; Queiroz, Maria Inês; Brandão, Tiago


    Historical perspective has revealed the many aspects of Portugal's interest in the sea, evident in a series of initiatives and entities throughout the twentieth century. From the beginning of the century until the 1974 Revolution, the genesis of organizations devoted to the scientific study of the sea is analyzed, observing their specific missions in the context of the formulation of science policy, and more specifically "ocean policies." The Portuguese valued knowledge of the sea due to their maritime vocation, coastal life and geographic position. Traversing different historical and political contexts and development cycles, the assumptions and political implications that accentuate the strategic dimension of science policy, visible in the geopolitical affirmation of oceanography, are studied.

    Favaro, Cleci Eulalia


    During their settlement of the so-called Old Italian Colonies of Rio Grande do Sul, immigrants constructed a set of positive values that were to serve as an emotional support and a means of outside communication. When women immigrants embroidered images and sayings on wall hangings or kitchen towels made of rustic fabric, they helped nourish the dream of a better life, sought by all and achieved by some. The objects crafted by these twentieth-century Penelopes bear witness to a way of doing, thinking, and acting. Local museums and exhibits have fostered the recovery of old-time embroidery techniques and themes; sold at open-air markets and regional festivals, these products represent income for women whose age excludes them from the formal labor market.

  16. Are Simulated and Observed Twentieth Century Tropical Pacific Sea Surface Temperature Trends Significant Relative to Internal Variability? (United States)

    Coats, S.; Karnauskas, K. B.


    Historical trends in the tropical Pacific zonal sea surface temperature gradient (SST gradient) are analyzed herein using 41 climate models (83 simulations) and 5 observational data sets. A linear inverse model is trained on each simulation and observational data set to assess if trends in the SST gradient are significant relative to the stationary statistics of internal variability, as would suggest an important role for external forcings such as anthropogenic greenhouse gasses. None of the 83 simulations have a positive trend in the SST gradient, a strengthening of the climatological SST gradient with more warming in the western than eastern tropical Pacific, as large as the mean trend across the five observational data sets. If the observed trends are anthropogenically forced, this discrepancy suggests that state-of-the-art climate models are not capturing the observed response of the tropical Pacific to anthropogenic forcing, with serious implications for confidence in future climate projections. There are caveats to this interpretation, however, as some climate models have a significant strengthening of the SST gradient between 1900 and 2013 Common Era, though smaller in magnitude than the observational data sets, and the strengthening in three out of five observational data sets is insignificant. When combined with observational uncertainties and the possibility of centennial time scale internal variability not sampled by the linear inverse model, this suggests that confident validation of anthropogenic SST gradient trends in climate models will require further emergence of anthropogenic trends. Regardless, the differences in SST gradient trends between climate models and observational data sets are concerning and motivate the need for process-level validation of the atmosphere-ocean dynamics relevant to climate change in the tropical Pacific.

    Recent studies indicate a weakening of the Walker Circulation during the twentieth century. Here, we present evidence from an atmospheric general circulation model (AGCM) forced by the history of observed sea surface temperature (SST) that the Walker Circulation may have intensified rather than weakened. Observed Equatorial Indo-Pacific Sector SST since 1870 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 western part and the Equatorial Indian Ocean exhibited a rather strong warming. This has resulted in an increase of the SST gradient between the Maritime Continent and the eastern part of the Equatorial Pacific, one driving force of the Walker Circulation. The ensemble experiments with the AGCM, with and without time-varying external forcing, suggest that the enhancement of the SST gradient drove an anomalous atmospheric circulation, with an enhancement of both Walker and Hadley Circulation. Anomalously strong precipitation is simulated over the Indian Ocean and anomalously weak precipitation over the western Pacific, with corresponding changes in the surface wind pattern. Some sensitivity to the forcing SST, however, is noticed. The analysis of twentieth century integrations with global climate models driven with observed radiative forcing obtained from the Coupled Model Intercomparison Project (CMIP) database support the link between the SST gradient and Walker Circulation strength. Furthermore, control integrations with the CMIP models indicate the existence of strong internal variability on centennial timescales. The results suggest that a radiatively forced signal in the Walker Circulation during the twentieth century may have been too weak to be detectable. (orig.)

  1. Revolutions in twentieth-century physics

    International Nuclear Information System (INIS)

    Griffiths, David J.


    Relativity theory, quantum mechanics, elementary-particle physics, and cosmology are the four pillars of modern physics. The life in the 21th century is without them no more conceivable: The special relativity theory renewed our understanding of space and time, on the laws of quantum mechanics are based countless everyday objects like transistors, computer chips, and mobile telephones; in particle accelerators we study the components oof matter, and with telescopes we take an ever deeper look in the past of the universe. Taking reference books to these themes at hand, one is overwhelmed by the plethora and complexity of the mathematical formulas. This book of the renowned professor of physics David J. Griffiths id refreshingly different. By means of many illustrative examples and entertaining stories it introducts to the themes and helps the reader also without a large mathematical apparatus to a fundamental understanding of that, about which Einstein, Schroedinger, Heisenberg, and Hubble actually thought and spoke. In each chapter numerous, pedagogically selected examples are completely worked out, in order to fill the matter with life. Moreover the text contains a manifold of problems, which allow the reader to deepen his knowledge and apply immediately. Griffith's ''Revolution in Twentieth Century Physics'' appeals not only to pupils and future studyings of natural sciences, who want to get an appetite for what lies ahead, but also to interested readers, which have already heared in the media from quarks and quanta, the curved space-time, Albert Einstein, and the big bang and now want to understandably know what is at stake in all the excitement.

  2. Imagining the Twentieth Century: Retrospective, Myth, and the Colonial Question

    Directory of Open Access Journals (Sweden)

    David B MacDonald


    Full Text Available Retrospectives on the twentieth century often portray it as the most atrocious century in human history, in terms of totalising ideologies, moral abandonment, technological horror, and mass death. The nineteenth and earlier centuries, by contrast, emerge as progressive and enlightened eras, characterised by morality, rationalism, and the absence of war. Creating a dramatic contrast between old and new centuries ignores the historical reality of colonialism and violence outside Europe’s borders. This article problematises twentieth century retrospectives and their nostalgia for the past, comparing these with recent histories of colonialism and genocide. Rather than see the twentieth century as a decisive break from the past, there are important elements of continuity and evolution which should not be ignored.

  6. Rethinking Folk Culture in Twentieth-Century Britain. (United States)

    Carter, Laura


    Research on folk culture in twentieth-century Britain has focused on elite and transgressive political episodes, but these were not its mainstream manifestations. This article re-evaluates the place of folk culture in twentieth-century Britain in the context of museums. It argues that in the modern heritage landscape folk culture was in an active dialogue with the modern democracy. This story begins with the vexed, and ultimately failed, campaign for a national English folk museum and is traced through the concurrent successes of local, regional, and Celtic 'first wave' folk museums across Britain from the 1920s to the 1960s. The educational activities of these museums are explored as emblematic of a 'conservative modernity', which gave opportunities to women but also restricted their capacity to do intellectual work. By the 1970s, a 'second wave' folk museology is identified, revealing how forms of folk culture successfully accommodated the rapid social change of the later twentieth century, particularly in deindustrializing regions. From this new, museums' perspective, folk culture appears far less marginal to twentieth-century British society. In museums folk culture interacted with mainstream concerns about education, regionalism, and commercialization. © The Author [2017]. Published by Oxford University Press.

  10. Aerological observations in the tropics in the early twentieth century

    Energy Technology Data Exchange (ETDEWEB)

    In the first decades of the 20{sup th} century, aerological observations were for the first time performed in tropical regions. One of the most prominent endeavours in this respect was Arthur Berson's aerological expedition to East Africa. Although the main target was the East African monsoon circulation, the expedition provided also other insights that profoundly changed meteorology and climatology. Berson observed that the tropical tropopause was much higher and colder than that over midlatitudes. Moreover, westerly winds were observed in the lower stratosphere, apparently contradicting the high-altitude equatorial easterly winds that were known since the Krakatoa eruption ('Krakatoa easterlies'). The puzzle was only resolved five decades later with the discovery of the Quasi-Biennial Oscillation (QBO). In this paper we briefly summarize the expedition of Berson and review the results in a historical context and in the light of the current research. In the second part of the paper we re-visit Berson's early aerological observations, which we have digitized. We compare the observed wind profiles with corresponding profiles extracted from the 'Twentieth Century Reanalysis', which provides global three-dimensional weather information back to 1871 based on an assimilation of sea-level and surface pressure data. The comparison shows a good agreement at the coast but less good agreement further inland, at the shore of Lake Victoria, where the circulation is more complex. These results demonstrate that Berson's observations are still valuable today as input to current reanalysis systems or for their validation. (orig.)

    The meaning and message of the history of science will be discussed with relevance to XX century physics. This decisive period began in 1894-95 with the discoveries of the electron,X-rays and radioactivity,with the consequent development of relativity and quantumphysics. Connections of the development of science and society in XX century with culture and the influence on industry will be examined. Finally, the corruption of physics by the military will be considered. The influence of physics on chemistry and biology will be briefly treated and the impact of the approach and method of physics on modern thinking will be assessed. It should be kept in mind that the history of science is not a way of getting a simplified or adulterated presentation of the subject ,in this case of physics and so some understanding of general physics will be assumed. On the other hand, the broader generalisations of the history of ideas and events are illustrated (if not proven) by the facts (and myths) of science. Finally,as an e...

  13. Mustaches and masculine codes in early twentieth-century America. (United States)

    Oldstone-Moore, Christopher


    The purpose of this article is to deepen our understanding of twentieth-century masculinity by considering the social function of facial hair. The management of facial hair has always been a medium of gendered body language, and as such has elicited a nearly continuous private and public conversation about manliness. Careful attention to this conversation, and to trends in facial hairstyles, illuminates a distinct and consistent pattern of thought about masculinity in early twentieth-century America. The preeminent form of facial hair - mustaches - was used to distinguish between two elemental masculine types: sociable and autonomous. A man was neither wholly one nor the other, but the presence and size of a mustache - or its absence - served to move a man one way or another along the continuum that stretched from one extreme to the other. According to the twentieth-century gender code, a clean-shaven man's virtue was his commitment to his male peers and to local, national or corporate institutions. The mustached man, by contrast, was much more his own man: a patriarch, authority figure or free agent who was able to play by his own rules. Men and women alike read these signals in their evaluation of men.

  14. The Long Twentieth Century and Barriers to China's Hegemonic Accession

    Directory of Open Access Journals (Sweden)

    John Gulick


    Full Text Available Giovanni Arrighi's The Long Twentieth Century is an almost unfathomably ambitious andcomplex work. Its monumentality derives from Arrighi 's conviction that the best way to handicapthe possible futures of the world capitalist geo-economy is to analyze the structural evolution ofthis global system, an evolution spanning more than five centuries; the genius of the work rests inthe distinctive approach that Arrighi takes. At the core of his approach is the identification ofthose long-term trends and accreted characteristics - one might call them "systemiccontradictions" - that promise to send the world capitalist geo-economy in a radically differentdevelopmental direction as US hegemony wanes. Arrighi 's assessment of these contradictionscompel him to make a provocative suggestion: in all likelihood, no singular concentration of stateand economic power possesses the territorial scale or the organizational capacities required tolead the global system through another round of restructuring and expansion. Properly framed,this illuminating insight could serve as the starting point for a theoretical exploration of thesocio-ecological constraints to global capitalist reproduction, but such is a journey (mostly nottaken by Arrighi in The Long Twentieth Century. In fact, to the degree that he subsequentlycontemplates the prospect of a China-centered reconstitution of the world geo-economy, Arrighimarginalizes the question of global systemic contradictions altogether.

  15. Global generations: social change in the twentieth century. (United States)

    Edmunds, June; Turner, Bryan S


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

  16. John Stewart Bell and twentieth century physics vision and integrity

    CERN Document Server

    Whitaker, Andrew


    John Stewart Bell (1928-1990) was one of the most important figures in twentieth-century physics, famous for his work on the fundamental aspects of the century's most important theory, quantum mechanics. While the debate over quantum theory between the supremely famous physicists, Albert Einstein and Niels Bohr, appeared to have become sterile in the 1930s, Bell was able to revive it and to make crucial advances - Bell's Theorem or Bell's Inequalities. He was able to demonstrate a contradiction between quantum theory and essential elements of pre-quantum theory - locality and causality. The book gives a non-mathematical account of Bell's relatively impoverished upbringing in Belfast and his education. It describes his major contributions to quantum theory, but also his important work in the physics of accelerators, and nuclear and elementary particle physics.

  17. Riemannian geometry during the second half of the twentieth century

    CERN Document Server

    Berger, Marcel


    In the last fifty years of the twentieth century Riemannian geometry has exploded with activity. Berger marks the start of this period with Rauch's pioneering paper of 1951, which contains the first real pinching theorem and an amazing leap in the depth of the connection between geometry and topology. Since then, the field has become so rich that it is almost impossible for the uninitiated to find their way through it. Textbooks on the subject invariably must choose a particular approach, thus narrowing the path. In this book, Berger provides a truly remarkable survey of the main developments in Riemannian geometry in the last fifty years, focusing his main attention on the following five areas: Curvature and topology; the construction of and the classification of space forms; distinguished metrics, especially Einstein metrics; eigenvalues and eigenfunctions of the Laplacian; the study of periodic geodesics and the geodesic flow. Other topics are treated in less detail in a separate section. Berger's survey p...

  18. Immigration, crime, and incarceration in early twentieth-century America. (United States)

    Moehling, Carolyn; Piehl, Anne Morrison


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

  19. Financial crises of the early twentieth century in Ukraine

    S.Z. Moshenskyi


    Full Text Available The article analyzes the major financial crises in Ukraine at early twentieth century dealing with the crises of 1899–1902 and 1908–1910. The main attention is paid to the large-scale crisis of 1899–1902 at the new industrial region in Eastern Ukraine where numerous steel and mining companies based on massive foreign investment (mainly Belgian and French were created shortly. The general boom of new joint-stock companies and insufficient provision of these companies by state orders were the main reason of the crisis which was the reflection of the international industrial and financial crisis of those years. The author also researches the crisis of 1908–1910 in the Ukrainian sugar industry.

  2. Memoirs a twentieth-century journey in science and politics

    CERN Document Server

    Teller, Edward


    The story of Edward Teller is the story of the twentieth century. Born in Hungary in 1908, Teller witnessed the rise of Nazism and anti-Semitism, two world wars, the McCarthy era, and the changing face of big science. A brilliant and controversial figure whose work on nuclear weapons was key to the American war effort, Teller has long believed in freedom through strong defense, a philosophy reflected in his stance on arms control and nuclear policy. These extraordinary recollections at last reveal the man behind the headlines-passionate and humorous, devoted and loyal. In clear and compelling prose, Teller tells of the people, events, and ideas that shaped him as a scientist, beginning with his early love of music and math, and continuing with his study of quantum physics with Werner Heisenberg. Present at many of the pivotal moments in modern science, Teller also describes his friendships with some of the century's greatest minds-Einstein, Bohr, Fermi, Szilard, von Neumann, Oppenheimer-and offers an honest a...

  3. Blackett physics, war, and politics in the twentieth century

    CERN Document Server

    Nye, Mary Jo


    This is a lively and compact biography of P. M. S. Blackett, one of the most brilliant and controversial physicists of the twentieth century. Nobel laureate, leader of operational research during the Second World War, scientific advisor to the British government, President of the Royal Society, member of the House of Lords, Blackett was also denounced as a Stalinist apologist for opposing American and British development of atomic weapons, subjected to FBI surveillance, and named as a fellow traveler on George Orwell’s infamous list. His service as a British Royal Navy officer in the First World War prepared Blackett to take a scientific advisory role on military matters in the mid-1930s. An international leader in the experimental techniques of the cloud chamber, he was a pioneer in the application of magnetic evidence for the geophysical theory of continental drift. But his strong political stands made him a polarizing influence, and the decisions he made capture the complexity of living a prominent twen...

  5. Twentieth century North Atlantic climate change. Part II: Understanding the effect of Indian Ocean warming

    Energy Technology Data Exchange (ETDEWEB)

    Hoerling, M.P.; Xu, T.; Bates, G.T. [Climate Diagnostics Center NOAA, Boulder, CO 80305-3328 (United States); Hurrell, J.W.; Phillips, A.S. [National Center for Atmospheric Research, Boulder, CO (United States)


    Ensembles of atmospheric general circulation model (AGCM) experiments are used in an effort to understand the boreal winter Northern Hemisphere (NH) extratropical climate response to the observed warming of tropical sea surface temperatures (SSTs) over the last half of the twentieth Century. Specifically, we inquire about the origins of unusual, if not unprecedented, changes in the wintertime North Atlantic and European climate that are well described by a linear trend in most indices of the North Atlantic Oscillation (NAO). The simulated NH atmospheric response to the linear trend component of tropic-wide SST change since 1950 projects strongly onto the positive polarity of the NAO and is a hemispheric pattern distinguished by decreased (increased) Arctic (middle latitude) sea level pressure. Progressive warming of the Indian Ocean is the principal contributor to this wintertime extratropical response, as shown through additional AGCM ensembles forced with only the SST trend in that sector. The Indian Ocean influence is further established through the reproducibility of results across three different models forced with identical, idealized patterns of the observed warming. Examination of the transient atmospheric adjustment to a sudden ''switch-on'' of an Indian Ocean SST anomaly reveals that the North Atlantic response is not consistent with linear theory and most likely involves synoptic eddy feedbacks associated with changes in the North Atlantic storm track. The tropical SST control exerted over twentieth century regional climate underlies the importance of determining the future course of tropical SST for regional climate change and its uncertainty. Better understanding of the extratropical responses to different, plausible trajectories of the tropical oceans is key to such efforts. (orig.)

    Full Text Available Data on the occurrence, biology, and historical background of the Atlantic salmon, Salmo salar L., (Pisces, Salmoniformes in the Elbe river basin (Europe, North Sea drainage area with a focus on Bohemian territory (Central Europe from the fourteenth to twentieth centuries are summarized in this paper. Historical methods of salmon fishing in Central Europe and historical legal protection of salmon in Bohemia are presented. The salmon is a model example of species which was extirpated as a result of anthropogenic changes in the landscape and rivers in some water systems. The human activities, such as stream bed regulation, dam system construction, other migration barriers, water pollution, fisheries exploitation, that led to the extirpation of Atlantic salmon in the Elbe river basin (are discussed. The last sporadic migrating native salmon were registered in the Bohemian section of the Elbe river basin in the mid twentieth century.

  11. Probabilistic precipitation and temperature downscaling of the Twentieth Century Reanalysis over France (United States)

    Caillouet, Laurie; Vidal, Jean-Philippe; Sauquet, Eric; Graff, Benjamin


    This work proposes a daily high-resolution probabilistic reconstruction of precipitation and temperature fields in France over the 1871-2012 period built on the NOAA Twentieth Century global extended atmospheric reanalysis (20CR). The objective is to fill in the spatial and temporal data gaps in surface observations in order to improve our knowledge on the local-scale climate variability from the late nineteenth century onwards. The SANDHY (Stepwise ANalogue Downscaling method for HYdrology) statistical downscaling method, initially developed for quantitative precipitation forecast, is used here to bridge the scale gap between large-scale 20CR predictors and local-scale predictands from the Safran high-resolution near-surface reanalysis, available from 1958 onwards only. SANDHY provides a daily ensemble of 125 analogue dates over the 1871-2012 period for 608 climatically homogeneous zones paving France. Large precipitation biases in intermediary seasons are shown to occur in regions with high seasonal asymmetry like the Mediterranean. Moreover, winter and summer temperatures are respectively over- and under-estimated over the whole of France. Two analogue subselection methods are therefore developed with the aim of keeping the structure of the SANDHY method unchanged while reducing those seasonal biases. The calendar selection keeps the analogues closest to the target calendar day. The stepwise selection applies two new analogy steps based on similarity of the sea surface temperature (SST) and the large-scale 2 m temperature (T). Comparisons to the Safran reanalysis over 1959-2007 and to homogenized series over the whole twentieth century show that biases in the interannual cycle of precipitation and temperature are reduced with both methods. The stepwise subselection moreover leads to a large improvement of interannual correlation and reduction of errors in seasonal temperature time series. When the calendar subselection is an easily applicable method suitable in

  11. The wisdom of elders: Inuvialuit social memories of continuity and change in the twentieth century. (United States)

    Lyons, Natasha


    The Inuvialuit of the Canadian Western Arctic are no strangers to change. From the arrival of whalers ca. 1890, they underwent a century of monumental societal upheaval. Perhaps against the odds, they sustained many of their traditional socioeconomic activities and continued to follow a land-based lifestyle through much of the twentieth century. With a few notable exceptions, historical accounts of this period were written by cultural outsiders who conveyed their own perspectives on Inuvialuit culture. This paper focuses on the social memories of present-day Inuvialuit Elders who recount aspects of their lifeways throughout the twentieth century, including seasonal practices, traditional skills they maintained, and responses to the historical events that challenged their ways of living and spurred continuous change. These oral narratives form part of a larger history for succeeding generations, and a platform from which to construct contemporary identities and to negotiate a collective future.

  12. Mutant utopias: evening primroses and imagined futures in early twentieth-century America. (United States)

    Endersby, Jim


    Hugo de Vries's mutation theory is now little more than a footnote to the history of biology, a failed theory that briefly led a few biologists astray. However, for the first quarter of the twentieth century it attracted considerable attention from both professional biologists and laypeople. De Vries's theory--together with the plant, Oenothera lamarckiana, that had supplied most of his evidence--became the focus of a surprising variety of imaginative hopes. Scientists and their various publics were fascinated by the utopian possibilities that the primrose seemed to offer, and their discussions shaped a public culture around biology that would help define the twentieth century as the "century of the gene." From a conventional history of science perspective (which, in the case of twentieth-century biology, often remains focused on the content of scientific theories and the professional communities that shaped them), the mutation theory seems unimportant. However, while De Vries's new theory of evolution ultimately failed to persuade the scientific community, it was much more important than is now realized, particularly because it helped make biology part of a wide variety of public debates. Understanding the mutation theory's story more fully suggests that we may need to rethink much of the rest of the century of the gene's history, to think less in terms of what happened in the lab and more about how biology came to function as public culture.

  14. Chinese Avant-garde Art in the Late Twentieth Century

    Directory of Open Access Journals (Sweden)

    Nataša Vampelj Suhadolnik


    Full Text Available The main topic of the present paper is the '85 Art Movement, which was the first significant nationwide Avant-garde art movement in China. This movement, which arose in the mid-80s, defined the aesthetic foundations and identity of contemporary Chinese art, and represented Chinese globalized society on the threshold of the 21st century. Whilst focusing on China’s specific cultural and political contexts, the present paper analyses the concepts of humanism (renwen 人文 and idea (guannian 觀念. The spirit of humanism, with a rationalist connotation, and the desire for a revolution of ideas were the two main factors underpinning the Chinese Avant-garde movement and its artistic expressions. The paper also shows that the '85 Art Movement did not stem solely from the socio-political challenges of the 1980s, but should be regarded in the wider context of the “modernization project of Chinese art”, in the early 20th century.

  16. One hundred years of alcoholism: the Twentieth Century. (United States)

    Mann, K; Hermann, D; Heinz, A


    The past 100 years witnessed the formation of a disease concept of alcoholism and a rapid increase in the knowledge of its aetiopathology and treatment options. In the first half of the century, public sanctions aimed at the abolition of alcoholism. In the United States, alcohol prohibition was revoked in the economic turmoil of the Great Depression. In Germany, proposed medical procedures to reduce the fertility of alcoholics had catastrophic consequences during the fascist dictatorship. A revived focus on alcoholics as patients with a right to medical treatment came out of self-organized groups, such as Alcoholics Anonymous. The current disease concept includes the psychosocial and neurobiological foundations and consequences of alcoholism. Neurobiological research points to the dispositional factor of monoaminergic dysfunction and indicates that neuroadaptation and sensitization may play a role in the maintenance of addictive behaviour. New treatment options include pharmacological approaches and indicate that behaviour and motivational therapy and the attendance of patient groups may equally reduce the relapse risk. The task of the future will be to apply scientific discoveries in the best interest of the patients and to support their efforts to be respected like subjects suffering from other diseases.

  17. The concept of time in early twentieth-century philosophy a philosophical thematic atlas

    CERN Document Server


    This book presents a collection of authoritative contributions on the concept of time in early twentieth-century philosophy. It is structured in the form of a thematic atlas: each section is accompanied by relevant elementary logic maps that reproduce in a “spatial” form the directionalities (arguments and/or discourses) reported on in the text. The book is divided into three main sections, the first of which covers phenomenology and the perception of time by analyzing the works of Bergson, Husserl, Sartre, Merleau-Ponty, Deleuze, Guattari and Derrida. The second section focuses on the language and conceptualization of time, examining the works of Cassirer, Wittgenstein, Heidegger, Lacan, Ricoeur and Foucault, while the last section addresses the science and logic of time as they appear in the works of Guillaume, Einstein, Reichenbach, Prigogine and Barbour. The purpose of the book is threefold: to provide readers with a comprehensive overview of the concept of time in early twentieth-century philosophy; ...

  18. How to manage a revolution: Isaac Newton in the early twentieth century (United States)

    Clarke, Imogen


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

  19. New perspectives on forced migration in the history of twentieth-century neuroscience. (United States)

    Stahnisch, Frank W; Russell, Gül


    This special issue of the Journal of the History of the Neurosciences, comprised of six articles and one commentary, reflects on the multifold dimensions of intellectual migration in the neurosciences and illustrates them by relevant case studies, biographies, and surveys from twentieth-century history of science and medicine perspectives. The special issue as a whole strives to emphasize the impact of forced migration in the neurosciences and psychiatry from an interdisciplinary perspective by, first, describing the general research topic, second, by showing how new models can be applied to the historiography and social studies of twentieth-century neuroscience, and, third, by providing a deeper understanding of the impact of European émigré researchers on emerging allied fields, such as neurogenetics, biological psychiatry, psychosomatics, and public mental health, etc. as resulting from this process at large.

  20. Rabid epidemiologies: the emergence and resurgence of rabies in twentieth century South Africa. (United States)

    Brown, Karen


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

  3. Hungarian Population Discourses in the Twentieth Century: The Problem of Declining Birth Rates


    Ildikó Szántó


    Falling birth rates had already been recorded as early as the late-eighteenth century in south-western Hungary in the Ormánság. Population loss from low birth rate remained one of the main topics writers and sociologists focused on in the twentieth century. The issue of Hungarian population decline was highlighted among the social ills in the interwar period, which was one of several subjects that divided intellectuals into ‘populists’ and ‘urbanites’. Following the impact of the low birth ra...

  5. Ocean heat content variability in an ensemble of twentieth century ocean reanalyses (United States)

    de Boisséson, Eric; Balmaseda, Magdalena Alonso; Mayer, Michael


    This paper presents a ten-member ensemble of twentieth century Ocean ReAnalyses called ORA-20C. ORA-20C assimilates temperature and salinity profiles and is forced by the ECMWF twentieth century atmospheric reanalysis (ERA-20C) over the 1900-2010 period. This study attempts to identify robust signals of ocean heat content change in ORA-20C and detect contamination by model errors, initial condition uncertainty, surface fluxes and observing system changes. It is shown that ORA-20C trends and variability in the first part of the century result from the surface fluxes and model drift towards a warmer mean state and weak meridional overturning circulation. The impact of the observing system in correcting the mean state causes the deceleration of the warming trend and alters the long-term climate signal. The ensemble spread reflects the long-lasting memory of the initial conditions and the convergence of the system to a solution compatible with surface fluxes, the ocean model and observational constraints. Observations constrain the ocean heat uptake trend in the last decades of the twentieth century, which is similar to trend estimations from the post-satellite era. An ocean heat budget analysis attributes ORA-20C heat content changes to surface fluxes in the first part of the century. The heat flux variability reflects spurious signals stemming from ERA-20C surface fields, which in return result from changes in the atmospheric observing system. The influence of the temperature assimilation increments on the heat budget is growing with time. Increments control the most recent ocean heat uptake signals, highlighting imbalances in forced reanalysis systems in the ocean as well as in the atmosphere.

  6. Surviving the Lunacy Act of 1890: English Psychiatrists and Professional Development during the Early Twentieth Century. (United States)

    Takabayashi, Akinobu


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

  8. In Referees We Trust? Controversies over Grant Peer Review in the Late Twentieth Century (United States)

    Baldwin, Melinda

    While many accounts of external refereeing assume that it has been a consistent part of science since the seventeenth century, the practice developed far more slowly and haphazardly than many observers realize, and it was not until after the Second World War that ''peer review'' became considered an essential part of scientific publishing or grant-making. This talk will explore refereeing procedures at American grant-giving organizations in the twentieth century, focusing especially on the National Science Foundation and the National Institutes of Health. The creators of the NSF and the NIH put refereeing systems in place at their foundation. However, the form and function of these systems differed from modern ''peer review'' in several important ways. At the NSF the initial purpose of the referee process was to advise the NSF program directors, not to dictate funding decisions. At the NIH, small ''study sections'' devoted to particular subjects made recommendations to the NIH leadership, which rendered final judgments. However, beginning in the 1960s a series of controversies about NIH and NSF grants placed refereeing procedures at these organizations under more intense scrutiny. These debates culminated in six days of Special Oversight Hearings into the NSF's peer review process in the summer of 1975. Following the hearings, both the NSF and NIH reformed their review processes to place more emphasis on referees' opinions about grant proposals, making peer review increasingly responsible for decision-making. These controversies illustrate that refereeing continued to undergo significant changes in form and purpose throughout the twentieth century, and further suggest that both the scientific community and the public placed increased emphasis on the role of the referee during the late twentieth century.

  9. Coupled Aerosol-Chemistry-Climate Twentieth-Century Transient Model Investigation: Trends in Short-Lived Species and Climate Responses (United States)

    Koch, Dorothy; Bauer, Susanne E.; Del Genio, Anthony; Faluvegi, Greg; McConnell, Joseph R.; Menon, Surabi; Miller, Ronald L.; Rind, David; Ruedy, Reto; Schmidt, Gavin A.; hide


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

  10. The riddle of sex: biological theories of sexual difference in the early twentieth-century. (United States)

    Ha, Nathan Q


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

  11. "Do grandmas have husbands?" Generational memory and twentieth-century women's lives. (United States)

    Alexander, Sally


    This essay uses memory in the ancient and modern sense of the "inner life of thought" to describe the formation of generational memory in a modern professional family whose twentieth-century history has been fractured by migration, war, education, and divorce. It is about the power of feeling and law, which framed the practical freedoms of twentieth-century women's lives and introduced the modern citizen in the aftermath of universal suffrage and world war. The first part of the essay emphasizes the psychic dimension of bodily feeling and drive in the formation of memory; a dimension overlooked by oral history and social movements, yet confirmed by autobiography and memoir. My granddaughter's questions provoked resistance as well as family stories, and let me observe the thought process in a child. Social history, autobiography, and personal memory confirm the common experience of everyday life reaching back through generations of London families; folklore, commerce, and family story make narratives of dreams, hopes, terrors, and events; a child's comprehension of the outside world is grasped through curiosity, imagination, and play in which bodily feeling is as powerful as speech and prohibition to make meanings that flow between inner world and external reality. The second half of the essay reflects on Joan Riviere's description of the self. Leading British psychoanalyst, translator of Freud, writing in the 1950s, Riviere's language of the inner world resonates with the liberal social ethics -- empathy, public service, common good -- which underpinned women's and human rights mid-twentieth century and the egalitarian and reproduction reforms whose universalism has been challenged since the 1970s. Negative feeling is striking in Riviere's description of the self -- fear, shame, shock, and trauma, which are confirmed in memoir and autobiography. In contrast, liberal social democratic accounts of the time idealized English character. Today, the future uncertain

  12. The Significance Of Space In Iris Murdoch’s The Unicorn As A Twentieth-Century Irish Gothic Novel

    Directory of Open Access Journals (Sweden)

    Jarząb Joanna


    Full Text Available During the twentieth century almost all literary genres came back to prominence in different and alternative forms. The Gothic is no exception to this phenomenon as many a writer made an attempt at using this eighteenth-century genre once again, but adding to it some contemporary elements. Consequently, an abundance of new techniques have been introduced to Gothic fiction to evoke the feeling of horror and terror among the more and more demanding readers of modern times. Still, some writers prefer to return to the traditional concept of the Gothic – as does Iris Murdoch in her novel The Unicorn. The purpose of this article is to analyse the text from the perspective of the Irish Gothic. Those features of the genre which are traditional as well as local are going to be discussed in the context of space as the dominating aspect of the novel. The typical Irish landscape abounding in marshes, bogs and the sea will be contrasted with the inner space of the house, and its resemblance to the old Victorian mansions popular among the Anglo-Irish ascendancy of nineteenth-century Ireland. In what follows, the paper aims at showing how Murdoch’s skilful play with the spatial differentiation between the inside and the outside dislodges other more universal issues, such as the question of freedom, of social taboos and of the different anxieties still present in Irish society today.

  15. Pain: metaphor, body, and culture in Anglo-American societies between the eighteenth and twentieth centuries. (United States)

    Bourke, Joanna


    This article explores the relationship between metaphorical languages, body, and culture, and suggests that such an analysis can reveal a great deal about the meaning and experience of pain in Anglo-American societies between the eighteenth and twentieth centuries. It uses concepts within embodied cognition to speculate on how historians can write a history of sensation. Bodies are actively engaged in the linguistic processes and social interactions that constitute painful sensations. Language is engaged in a dialogue with physiological bodies and social environments. And culture collaborates in the creation of physiological bodies and metaphorical systems.

  16. The State of Native America at the End of the Twentieth Century

    Directory of Open Access Journals (Sweden)

    J. Kelly Robison


    Full Text Available When stereotypes of modern Native Americans are brought forward, these usually manifest themselves in visions of poor Indians living on reservations, which are on lands no one else wanted. Modern Native Americans are often stereotyped as drunks or succumbing to the pressure of gamblers to open their reservations to casinos. One place to start in order to disprove these stereotypes is the statistical data. What follows is not an interpretive essay in the classic scholarly vein, but an informative one that provides a picture of the state of Native America at the end of the Twentieth Century based on current statistical data.

  17. [Constant or break? On the relations between human genetics and eugenics in the Twentieth Century]. (United States)

    Germann, Pascal


    The history of human genetics has been a neglected topic in history of science and medicine for a long time. Only recently, have medical historians begun to pay more attention to the history of human heredity. An important research question deals with the interconnections between human genetics and eugenics. This paper addresses this question: By focusing on a Swiss case study, the investigation of the heredity of goiter, I will argue that there existed close but also ambiguous relations between heredity research and eugenics in the twentieth century. Studies on human heredity often produced evidence that challenged eugenic aims and ideas. Concurrently, however, these studies fostered visions of genetic improvement of human populations.

  19. Hydrotherapy in state mental hospitals in the mid-twentieth century. (United States)

    Harmon, Rebecca Bouterie


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

  20. Buddhism, Christianity, and psychotherapy: A three-way conversation in the mid-twentieth century. (United States)

    Harding, Christopher


    This article explores the scope of 'religion-psy dialogue' in the mid-twentieth century, via a case study from Japan: Kosawa Heisaku, a Buddhist psychoanalyst based in Tokyo. By putting this case study in brief comparative perspective, with the conversation that took place in 1965 between Paul Tillich and Carl Rogers, the article discusses both the promise and the pitfalls of the modern and contemporary world of 'religion-psy dialogue', alongside the means by which specialists in a variety of fields might investigate and hold it to account.

  1. Probabilistic precipitation and temperature downscaling of the Twentieth Century Reanalysis over France (United States)

    Caillouet, Laurie; Vidal, Jean-Philippe; Sauquet, Eric; Graff, Benjamin


    considered to correct monthly precipitation and temperature time series. The first one applies two new analogy steps, using the sea surface temperature (SST) and the large-scale two-meter temperature. The second method is a calendar selection that keeps the closest analogue dates in the year for each target date. A sensitivity study has been performed to assess the final number of analogues dates to retain for each method. A comparison to Safran over 1958-2010 shows that biases on the interannual cycle of precipitation and temperature are strongly reduced with both methods. Using two supplementary analogy levels moreover leads to a large improvement of correlation in seasonal temperature time series. These two methods have also been validated before 1958 thanks to both raw observations and homogenized time series. The two post-processing methods come with some advantages and drawbacks. The calendar selection allows to slightly better correct for seasonal biases in precipitation and is therefore adapted in a forecasting context. The selection with two supplementary analogy levels would allow for possible season shifts and SST trends and is therefore better suited for climate reconstruction and climate change studies.

  2. The concept of ‘transcendence’ in modern Western philosophy and in twentieth century Hindu thought

    Directory of Open Access Journals (Sweden)

    Ferdinando SARDELLA


    Full Text Available ‘Transcendence’ has been a key subject of Western philosophy of religion and history of ideas. The meaning of transcendence, however, has changed over time. The article looks at some perspectives offered by the nineteenth and the twentieth century Anglo‑American and continental European philosophers of religion and presents their views in relation to the concept of transcendence formulated by the Bengali Hindu traditionalist Bhaktisiddhanta Sarasvati (1874–1937. The questions raised are what transcendence in the philosophy of religion is, how one can speak of it, and what its goal is. The paper points to parallels and differences in epistemology, ontology and practice. One difference is that the nineteenth and the twentieth century Western philosophy of religion tended to assume an ontological difference between self and transcendence inherited from personalities such as Søren Kierkegaard, but also to explore the concept of transcendence beyond the idea of a metaphysical God. Bhaktisiddhanta, whose foundational thought mirrors medieval Hindu philosophy of religion and the theistic schools of Vedānta, suggests that transcendence has a metaphysical and personal dimension that is to some degree ontologically similar to and directly knowable by the self. Bhaktisiddhanta’s approach to transcendence differs from Kierkegaard’s and other Western philosophers’ and revolves around the idea of God as a transcendent person that can be directly known morphologically and ontologically through devotion. The article is a contribution to the history of ideas and the philosophy of religion in Eurasia and beyond.

  3. The holist tradition in twentieth century genetics. Wilhelm Johannsen's genotype concept. (United States)

    Roll-Hansen, Nils


    The terms 'genotype', 'phenotype' and 'gene' originally had a different meaning from that in the Modern Synthesis. These terms were coined in the first decade of the twentieth century by the Danish plant physiologist Wilhelm Johannsen. His bean selection experiment and his theoretical analysis of the difference between genotype and phenotype were important inputs to the formation of genetics as a well-defined special discipline. This paper shows how Johannsen's holistic genotype theory provided a platform for criticism of narrowly genocentric versions of the chromosome theory of heredity that came to dominate genetics in the middle decades of the twentieth century. Johannsen came to recognize the epoch-making importance of the work done by the Drosophila group, but he continued to insist on the incompleteness of the chromosome theory. Genes of the kind that they mapped on the chromosomes could only give a partial explanation of biological heredity and evolution. © 2014 The Author.

  4. The acceleration of the masculine in early-twentieth-century Berlin. (United States)

    Prickett, David James


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

  5. Continuum mechanics through the ages from the renaissance to the twentieth century : from hydraulics to plasticity

    CERN Document Server

    Maugin, Gérard A


    Mixing scientific, historic and socio-economic vision, this unique book complements two previously published volumes on the history of continuum mechanics from this distinguished author. In this volume, Gérard A. Maugin looks at the period from the renaissance to the twentieth century and he includes an appraisal of the ever enduring competition between molecular and continuum modelling views. Chapters trace early works in hydraulics and fluid mechanics not covered in the other volumes and the author investigates experimental approaches, essentially before the introduction of a true concept of stress tensor. The treatment of such topics as the viscoelasticity of solids and plasticity, fracture theory, and the role of geometry as a cornerstone of the field, are all explored. Readers will find a kind of socio-historical appraisal of the seminal contributions by our direct masters in the second half of the twentieth century. The analysis of the teaching and research texts by Duhem, Poincaré and Hilbert on cont...

  6. Pioneers of Gentrification: Transformation in Global Neighborhoods in Urban America in the Late Twentieth Century. (United States)

    Hwang, Jackelyn


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

  7. Real Men Wear Uniforms: Photomontage, Postcards, and Military Visual Culture in Early Twentieth-Century Germany

    Directory of Open Access Journals (Sweden)

    Elizabeth Otto


    Full Text Available This essay examines early twentieth-century German representations of men and women in uniform to consider how mass culture allowed individuals to participate in aspects of gender construction. It also reveals how masculinity was increasingly linked to military ideals. The pictures under scrutiny here were made in two significant but as yet under-researched types of pictures: pre-avant-garde photomontaged soldier portraits and popular postcards. Both of these visual forms originated in the 1870s, the decade that Germany was itself founded, and they both were in wide circulation by the early twentieth century. Individualized soldier portraits and postcards offered a glorious vision of a man’s military service, and they performed what Theodor Lessing has called Vergemütlichung, the rendering harmless of history. These idealized images of soldierly life were available to a broad swath of the public, but their democratization only extended so far. Representations of women in uniform served to reinforce—through stereotyping and humor—the unquestionably male nature of military institutions and, by extension, of public space. At the same time, by making apparent their own constructed nature, these portraits and postcards offered viewers a glimpse behind the masquerade of masculinity. This essay thus also identifies these images’ links to the subsequent work of avant-garde artists and to the National Socialists’ return to the ideal of uniformed masculinity.

  9. Landlordism, Rent Regulation and the Labour Party in mid-twentieth century Britain, 1950-64. (United States)

    Child, Phil


    This article examines the politics of private renting in 1950s and early 1960s Britain, through the radical approach taken by Labour Party towards private landlords. Through setting the radical aims of Labour in a mid-twentieth-century context of decrepit housing, rising rents and sluggish public housing programmes, Labour's rationale in arguing for the 'abolition' of the private landlord is more transparent. This article takes a chronological approach, investigating what actions Labour actors took, at local and national level, and what effect this had on the wider housing market. Part one takes a long view of Labour attitudes to the private rented sector. Part two explores the policy of 'municipalization'-the attempt to place rented homes under local authority control. Part three discusses the post-1962 policy shift to state-sponsored 'improvement' of private rented housing, prior to Labour's victory at the 1964 general election. Three key arguments are made: that Labour's radicalism hastened the collapse of the post-war private rented sector; that rental market weaknesses indicated the confused place of renting in the 'tenurial pattern'; and that the proposed 'abolition' of private landlords had a direct effect on slum clearance and the composition of British cities. The conclusion suggests that Labour's pursuit of the private landlord can shed light on the vast urban transformations of the post-war period. It invites greater attention to be paid to the effects that political ideas had on the composition of the twentieth-century British housing market.

    Costea, Claudia Florida; Turliuc, Şerban; Buzdugă, Cătălin; Cucu, Andrei Ionuţ; Dumitrescu, Gabriela Florenţa; Sava, Anca; Turliuc, Mihaela Dana


    The optic chiasm is an essential structure located at the skull base that stirred over time the curiosity of anatomists, who became more and more interested in its structure and function. Through centuries, the optic chiasm was viewed as a vessel crossing, a way of transporting tears secreted by the brain to the eye, integrating images, or responsible for coordinated eye movements. The paper aims to overview the history of understanding the optic chiasm from the beginnings of antiquity to the twentieth century. We reviewed the literature and studied all the historical sources on optic chiasm and eyes in the works of ancient, medieval, Renaissance authors, and the seventeenth to nineteenth century works. The optic chiasm is a structure that fascinated ancient anatomists and made them develop various theories on its function. In terms of function, the optic chiasm had a history based more on speculation, the seventeenth century bringing its first understanding and reaching the peak in the nineteenth century with the understanding of the anatomical structure of the chiasm and its role in the visual process. The history of the optic chiasm is a fascinating time travel displaying the conceptual transformations that have been made in anatomy and medicine by our forerunners.

  11. ‘Canonization in early twentieth-century Chinese art history’

    Directory of Open Access Journals (Sweden)

    Guo Hui


    Full Text Available Since the 1980s, the discussion of canons has been a dominant theme in the discipline of Western art history. Various concerns have emerged regarding ‘questions of artistic judgment’, ‘the history genesis of masterpieces’, ‘variations in taste’, ‘the social instruments of canonicity’, and ‘how canons disappear’. Western art historians have considered how the canon’s appearance in Western visual art embodies aesthetic, ideological, cultural, social, and symbolic values. In Chinese art history, the idea of a canon including masterpieces, important artists, and forms of art, dates back to the mid ninth century when Zhang Yanyuan wrote his painting history Record of Famous Painters of All the Dynasties. Faced with quite different political, economic, and social conditions amid the instability of the early twentieth century, Chinese scholars attempted to discover new canons for cultural orthodoxy and authority. Modern means for canonization, such as museums and exhibition displays, cultural and academic institutions, and massive art publications with image reproduction in good quality, brought the process up to an unprecedented speed. It is true that most of these means have comparable counterparts in pre-modern times. However, their enormous scope and overwhelming influence are far beyond the reach of their imperial counterparts. Through an inter-textual reading of the publications on Chinese art history in early twentieth-century China, this paper explores the transformation of canons in order to shed light on why and how canonical formation happened during the Republican period of China. Despite the diverse styles and strategies which Chinese writers used in their narratives, Chinese art historical books produced during the Republican period canonized and de-canonized artworks. In this paper, the discussion of these texts, with reference to other art historical works, comprises three parts: 1 canon formation of artistic forms

  12. The Representation of Jews in Nineteenth- and Twentieth-Century Hungarian Proverb Collections

    Directory of Open Access Journals (Sweden)

    Ilana Rosen


    Full Text Available Proverbs are concise formulations of folk wisdom and as such, when seen in masses, they may well express the spirit of their time and place. In Hungarian proverbial lore Jews figure prominently in nineteenth-century proverb collections but fade out of such collections as of the mid-twentieth century. In the nineteenth-century proverb collections Jews are invariably portrayed as faithless, dishonest, greedy, physically weak and unattractive. Largely, this portrayal as well as the dynamics of the earlier presence of Jews versus their later disappearance from Hungarian proverb collections match the shared history of Hungarians and Hungarian Jews since the 1867 Emancipation of the country's Jews and possibly even earlier, through their growing integration in significant arenas of their host society, up to their persecution and annihilation in the Holocaust, and later their decade long forced merging into the general Hungarian society under communism. This article traces the occurrence and disappearance of Jews in Hungarian proverb collections throughout the last two centuries and analyzes the language, content and messages of the proverbs about Jews in these collections.

  13. BOOK REVIEW: Quantum Generations. A history of physics in the twentieth century (United States)

    Brown, Neil


    Physics has a long history, but more physics has been discovered in the twentieth century than in all previous eras together. That in itself would be a sufficient justification for a history of physics in the twentieth century, but the end of the previous century also marked a discontinuity, from Newtonian classical physics to relativity and quantum mechanics. If any single event marks the start of the process it is the discovery of x-rays in 1895, and Kragh's century spans from about 1895 to about 1995. It is, of course, too much for a single volume, even a large one, and Kragh recognizes from the outset that he has to be selective and concentrate on those subjects that define twentieth-century physics. For the early part of the century the author relies on carefully chosen secondary sources, to avoid the near-impossible task of absorbing a multitude of original papers. The recent period is more difficult, and the sources are articles, reviews, and the recollections of physicists. The book is in three main sections, roughly to the end of World War I, to the end of World War II, and up to 1995, plus a retrospective summary. It deals with more than just discoveries in physics, looking also at physicists and institutions, and at their interactions with the rest of society. The broad outlines of many discoveries are often known to physicists who have no special interest in history, and Kragh is careful to point out where these conventional accounts are inadequate. The first chapters set the scene at the end of the nineteenth century, acknowledging that there was a belief that all the grand underlying principles had been established, but also pointing out that there was a ferment of attempts to reinterpret physics in terms of concepts like vortices and hyperspaces. The history begins with the mould-breaking discoveries of x-rays, radioactivity and the electron. The chapters that follow look at theories about atomic structure, and at quantum physics, relativity and

  14. The reinvention of twentieth century microscopy for three-dimensional imaging. (United States)

    Whitehead, Lachlan W; McArthur, Kate; Geoghegan, Niall D; Rogers, Kelly L


    In just over a decade, the field of biomedical research has witnessed a radical evolution in technologies for the 3- and 4-dimensional imaging of biological samples. Light sheet fluorescence microscopy is quickly developing into a powerful approach for fast, volumetric imaging of cells, tissues and living organisms. This review touches on the development of 3-dimensional imaging, from its foundations, namely from the invention of confocal microscopy in the twentieth century to more recent examples, notably the IsoView SPIM, the Lattice Light Sheet Microscope and swept confocally aligned planar excitation. These technologies overcome the limitations of conventional optical sectioning techniques and enable unprecedented levels of spatio-temporal resolution with low levels of phototoxicity. Developing in parallel with powerful computational approaches, light sheet based methods promise to completely transform cell biology as we know it today.

  15. Hidden in plain sight marketing prescription drugs to consumers in the twentieth century. (United States)

    Greene, Jeremy A; Herzberg, David


    Although the public health impact of direct-to-consumer (DTC) pharmaceutical advertising remains a subject of great controversy, such promotion is typically understood as a recent phenomenon permitted only by changes in federal regulation of print and broadcast advertising over the past two decades. But today's omnipresent ads are only the most recent chapter in a longer history of DTC pharmaceutical promotion (including the ghostwriting of popular articles, organization of public-relations events, and implicit advertising of products to consumers) stretching back over the twentieth century. We use trade literature and archival materials to examine the continuity of efforts to promote prescription drugs to consumers and to better grapple with the public health significance of contemporary pharmaceutical marketing practices.

  18. Physiology, propaganda, and pound animals: medical research and animal welfare in mid-twentieth century America. (United States)

    Parascandola, John


    In 1952, the University of Michigan physiologist Robert Gesell shocked his colleagues at the business meeting of the American Physiological Society by reading a prepared statement in which he claimed that some of the animal experimentation being carried out by scientists was inhumane. He especially attacked the National Society for Medical Research (NSMR), an organization that had been founded to defend animal experimentation. This incident was part of a broader struggle taking place at the time between scientists and animal welfare advocates with respect to what restrictions, if any, should be placed on animal research. A particularly controversial issue was whether or not pound animals should be made available to laboratories for research. Two of the prominent players in this controversy were the NSMR and the Animal Welfare Institute, founded and run by Gesell's daughter, Christine Stevens. This article focuses on the interaction between these two organizations within the broader context of the debate over animal experimentation in the mid-twentieth century.

  19. Thomson, his discovery of the electron and the twentieth century science and technology

    International Nuclear Information System (INIS)

    Ahmad, N.


    Sir J. J. Thomson was the first to discover a subatomic particle i. e. electron. Due to this discovery he is remembered in the history as T he Atom Smasher . He was a great experimentalists and a devoted physicist. He himself, his son and his seven pupils earned Noble prizes on the basis of their scientific discoveries. The discovery of electron by Sir Thomson in 1897, at Cavendish Laboratory, has rewritten the entire physical science. Although electron has wide spread applications in almost every field, yet its exact nature is not fully known. This article briefly describes the life of Sir Thomson, his achievements and the impact of his discovery of electron on the twentieth century science and technology. (author)

  20. Intellectual disability, mental illness and offending behaviour: forensic cases from early twentieth-century Ireland. (United States)

    Kelly, B D


    The history of institutional care for individuals with intellectual disability is under-researched, complex and troubling. To explore the experiences of women who may have had intellectual disability and/or mental illness and were admitted to forensic psychiatric care in early twentieth-century Ireland. All female case records at the Central Mental Hospital, Dublin from 1910 to 1948 (n = 42) were studied for evidence of possible intellectual disability and a series of five cases is presented in detail. These committals occurred in the context of adverse social conditions, over-crowding in asylums and a belief that rates of mental illness were rising. Particular challenges included diagnostic issues (especially in relation to intellectual disability), adjustment to asylum environments, mental illness and physical ill-health. The institutional experiences of individuals with intellectual disability represents an important area for further historical research, using larger and more varied forensic populations.

  1. Léon Rosenfeld physics, philosophy, and politics in the twentieth century

    CERN Document Server

    Jacobsen, Anja Skaar


    This book is a social-intellectual biography of the Belgian physicist Léon Rosenfeld (1904-1974). Rosenfeld was at the center of modern theoretical physics and he became the Danish physicist Niels Bohr's right-hand man. Rosenfeld was a perceptive, polyglot cosmopolitan, whose life crossed those of many important people in many countries. He was also a strong integrated personality capable of performing exotic calculations at one moment, while disentangling subtle philosophical questions or intervening in a political discussion the next — all at the highest level. This book aims at a broad audience interested in contextual history of twentieth century physics. No specialized knowledge of physics is required to read it.

  3. Alfred Owre: revisiting the thought of a distinguished, though controversial, early twentieth-century dental educator. (United States)

    Nash, David A


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

  5. Natural histories of infectious disease: ecological vision in twentieth-century biomedical science. (United States)

    Anderson, Warwick


    During the twentieth century, disease ecology emerged as a distinct disciplinary network within infectious diseases research. The key figures were Theobald Smith, F. Macfarlane Burnet, René Dubos, and Frank Fenner. They all drew on Darwinian evolutionism to fashion an integrative (but rarely holistic) understanding of disease processes, distinguishing themselves from reductionist "chemists" and mere "microbe hunters." They sought a more complex, biologically informed epidemiology. Their emphasis on competition and mutualism in the animated environment differed from the physical determinism that prevailed in much medical geography and environmental health research. Disease ecology derived in part from studies of the interaction of organisms - micro and macro - in tropical medicine, veterinary pathology, and immunology. It developed in postcolonial settler societies. Once a minority interest, disease ecology has attracted more attention since the 1980s for its explanations of disease emergence, antibiotic resistance, bioterrorism, and the health impacts of climate change.

  6. Taming the unknown a history of algebra from antiquity to the early twentieth century

    CERN Document Server

    Katz, Victor J


    What is algebra? For some, it is an abstract language of x's and y's. For mathematics majors and professional mathematicians, it is a world of axiomatically defined constructs like groups, rings, and fields. Taming the Unknown considers how these two seemingly different types of algebra evolved and how they relate. Victor Katz and Karen Parshall explore the history of algebra, from its roots in the ancient civilizations of Egypt, Mesopotamia, Greece, China, and India, through its development in the medieval Islamic world and medieval and early modern Europe, to its modern form in the early twentieth century. Defining algebra originally as a collection of techniques for determining unknowns, the authors trace the development of these techniques from geometric beginnings in ancient Egypt and Mesopotamia and classical Greece. They show how similar problems were tackled in Alexandrian Greece, in China, and in India, then look at how medieval Islamic scholars shifted to an algorithmic stage, which was further dev...

  7. Causes and impacts of changes in the Arctic freshwater budget during the twentieth and twenty-first centuries in an AOGCM

    Energy Technology Data Exchange (ETDEWEB)

    Arzel, Olivier [University of New South Wales, Climate and Environmental Dynamics Laboratory, School of Mathematics and Statistics, Sydney, NSW (Australia); Fichefet, Thierry; Goosse, Hugues [Universite Catholique de Louvain, Institut d' Astronomie et de Geophysique G. Lemaitre, Louvain-la-Neuve (Belgium); Dufresne, Jean-Louis [Institut Pierre Simon Laplace UPMC/CNRS, Laboratoire de Meteorologie Dynamique, Paris (France)


    The fourth version of the atmosphere-ocean general circulation (AOGCM) model developed at the Institut Pierre-Simon Laplace (IPSL-CM4) is used to investigate the mechanisms influencing the Arctic freshwater balance in response to anthropogenic greenhouse gas forcing. The freshwater influence on the interannual variability of deep winter oceanic convection in the Nordic Seas is also studied on the basis of correlation and regression analyses of detrended variables. The model shows that the Fram Strait outflow, which is an important source of freshwater for the northern North Atlantic, experiences a rapid and strong transition from a weak state toward a relatively strong state during 1990-2010. The authors propose that this climate shift is triggered by the retreat of sea ice in the Barents Sea during the late twentieth century. This sea ice reduction initiates a positive feedback in the atmosphere-sea ice-ocean system that alters both the atmospheric and oceanic circulations in the Greenland-Iceland-Norwegian (GIN)-Barents Seas sector. Around year 2080, the model predicts a second transition threshold beyond which the Fram Strait outflow is restored toward its original weak value. The long-term freshening of the GIN Seas is invoked to explain this rapid transition. It is further found that the mechanism of interannual changes in deep mixing differ fundamentally between the twentieth and twenty-first centuries. This difference is caused by the dominant influence of freshwater over the twenty-first century. In the GIN Seas, the interannual changes in the liquid freshwater export out of the Arctic Ocean through Fram Strait combined with the interannual changes in the liquid freshwater import from the North Atlantic are shown to have a major influence in driving the interannual variability of the deep convection during the twenty-first century. South of Iceland, the other region of deep water renewal in the model, changes in freshwater import from the North Atlantic

  8. Hungarian Population Discourses in the Twentieth Century: The Problem of Declining Birth Rates

    Directory of Open Access Journals (Sweden)

    Ildikó Szántó


    Full Text Available Falling birth rates had already been recorded as early as the late-eighteenth century in south-western Hungary in the Ormánság. Population loss from low birth rate remained one of the main topics writers and sociologists focused on in the twentieth century. The issue of Hungarian population decline was highlighted among the social ills in the interwar period, which was one of several subjects that divided intellectuals into ‘populists’ and ‘urbanites’. Following the impact of the low birth rate figures in the 1960s, the populists’ views of the 1930s resurfaced in public discourse in the 1960s and 1970s and up to the present day. The concern about the increasing trend of single-child families in rural settlements as well as in urban areas appeared in the various works of Hungarian writers and journalists throughout the previous century. The present paper intends to focus on the intellectual background to the public debates on the population issue, outlining the accounts of the interwar ‘village explorers’ briefly, and the way they are related to the pre-Second World War populist movement. Finally the reappearance of the debates between populists and non-populists of the 1970s is discussed, a debate that is still continuing.

  9. Communal Cattle in Mixteca Alta: From Colonial Times to the Twentieth Century. The Case of Tepelmeme

    Directory of Open Access Journals (Sweden)

    Edgar Mendoza García


    Full Text Available This is an analysis of the political  and economic factors than allowed the keeping of a herd of goats as communal property from the  república de indios of the colonial period until municipal administrations at the beginning of the twentieth century  in the region called the Mixteca Alta. The case of Tepelmeme, Oaxaca, is the basis of an account of the economic importance of communal property in the local governments of villages and  municipios, as well of the opposition of villages to liberal laws of the nineteenth century. In short, during the colonial period and part of the nineteenth century,  communal property was the main economic support of Indian villages. Not only was this property equivalent to communal  savings kept  for  critical  moments, but  also  an  economic means  that  allowed financing public  administration and  paying for religious services. Moreover, it was a factor that gave cohesion to these villages and inserted them into a regional economy.

  10. Building Baluchitherium and Indricotherium: imperial and international networks in early-twentieth century paleontology. (United States)

    Manias, Chris


    Over the first decades of the twentieth century, the fragmentary remains of a huge prehistoric ungulate were unearthed in scientific expeditions in India, Turkestan and Mongolia. Following channels of formal and informal empire, these were transported to collections in Britain, Russia and the United States. While striking and of immense size, the bones proved extremely difficult to interpret. Alternately naming the creature Paraceratherium, Baluchitherium and Indricotherium, paleontologists Clive Forster-Cooper, Alexei Borissiak and Henry Fairfield Osborn struggled over the reconstruction of this gigantic fossil mammal. However, despite these problems, shared work on the creature served as a focus for collaboration and exchange rather than rivalry between these three scientific communities. Not only did the initial interpretation and analysis depend on pre-existing connections between British and American paleontological institutions, but the need for comparative material, recognition and contacts brought British and American scholars into communication and exchange with their counterparts in the Soviet Union. This article examines these processes. It first uses these excavations as a comparative case-study of different manifestations of colonial science in this period, examining how scholars in the Britain, the Russian Empire and the United States used formal and informal colonial links to Asia to pursue new research. It then moves to examine how the common problem of reconstructing this giant animal drew metropolitan scientific communities together, at least for a time. The construction of the Baluchitherium and Indricotherium illustrates the drives to expand research both imperially and internationally in the early-twentieth century, but also the continual problems in resources, institutionalization, transport and communication that could run up against scientific work.

    Andrés Fortunato


    Full Text Available In this work I analyze the theories of Carl Schmitt and Hans Kelsen of democracy in the light of the weberian topic of rationalization. My thesis is that this counterpoint does not escape the contemporary split that characterizes the nineteenth century modernity and continues in the twentieth century. At last, I’ll maintain that the political manifestation of this aporeticalbackground –over which one must understand the challenge of democracy– is what Schmitt calls the total State.

  19. Theory versus Practice in the Twentieth-Century Search for the Ideal Anaesthetic Gas. (United States)

    Rae, Ian D


    At the beginning of the twentieth century, an anaesthetist could choose between nitrous oxide, chloroform, and ether (diethyl ether) for the induction of painrelieving unconsciousness. By the end of century, the choice was between a small number of fluorinated aliphatic ethers such as Enflurane, Desflurane, and Sevoflurane, and (in some jurisdictions) the rare gas, xenon. Between these endpoints researchers had identified a surprisingly broad range of hydrocarbons, noble gases, organohalogens, and aliphatic ethers that possessed anaesthetic properties. None was entirely satisfactory, but clinicians at various times and in various places employed substances in each of these categories. Behind the search for new anaesthetic gases was a theory of action (Meyer- Overton theory) that was known to be inadequate, but as no alternative was strong enough to displace it the search continued on purely empirical grounds, while lip-service was paid to the theory. By the time a theory couched in more modern terms was proposed, a suite of modern anaesthetic gases was in place, and there have been no attempts to use that theory to drive a new search.

  20. Economic performance and public concerns about social class in twentieth-century books. (United States)

    Chen, Yunsong; Yan, Fei


    What is the association between macroeconomic conditions and public perceptions of social class? Applying a novel approach based on the Google Books N-gram corpus, this study addresses the relationship between public concerns about social class and economic conditions throughout the twentieth century. The usage of class-related words/phrases, or "literary references to class," in American English-language books is related to US economic performance and income inequality. The findings of this study demonstrate that economic conditions play a significant role in literary references to class throughout the century, whereas income inequality does not. Similar results are obtained from further analyses using alternative measures of class concerns as well as different corpora of English Fiction and the New York Times. We add to the social class literature by showing that the long-term temporal dynamics of an economy can be exhibited by aggregate class concerns. The application of massive culture-wide content analysis using data of unprecedented size also represents a contribution to the literature. Copyright © 2016 Elsevier Inc. All rights reserved.

  1. "For ever and ever": Child-raising, domestic workers and emotional labour in twentieth century Britain

    Directory of Open Access Journals (Sweden)

    Lucy Delap


    Full Text Available The relationships of physical and emotional labour which exist between children, parents and domestic workers are historically fluid. Different styles of parenting, discourses of social class, and material contexts of care have given rise to very diverse degrees of delegation of childcare to servants. Servants themselves have often invested emotionally in their relationships with children, and the relationship has clearly not been simply commodified in being delegated. However, the relationships that result have sometimes been troubled and ambivalent. A simple narrative of exploitation does little to capture the experiences of servants who cared for children, and the recent historiography of emotions and emotional labour can help to trace a fuller picture. In this paper, I examine the roles of laughter as a form of emotional expression that can shed light on the affects of care – the shared jokes, failed jokes and forms of mockery that characterised the management of servants by mothers who employed them, or the experiences of servants and children in late nineteenth and twentieth century servant-keeping houses.

  2. Twentieth-Century Hydrometeorological Reconstructions to Study the Multidecadal Variations of the Water Cycle Over France (United States)

    Bonnet, R.; Boé, J.; Dayon, G.; Martin, E.


    Characterizing and understanding the multidecadal variations of the continental hydrological cycle is a challenging issue given the limitation of observed data sets. In this paper, a new approach to derive twentieth century hydrological reconstructions over France with an hydrological model is presented. The method combines the results of long-term atmospheric reanalyses downscaled with a stochastic statistical method and homogenized station observations to derive the meteorological forcing needed for hydrological modeling. Different methodological choices are tested and evaluated. We show that using homogenized observations to constrain the results of statistical downscaling help to improve the reproduction of precipitation, temperature, and river flows variability. In particular, it corrects some unrealistic long-term trends associated with the atmospheric reanalyses. Observationally constrained reconstructions therefore constitute a valuable data set to study the multidecadal hydrological variations over France. Thanks to these reconstructions, we confirm that the multidecadal variations previously noted in French river flows have mainly a climatic origin. Moreover, we show that multidecadal variations exist in other hydrological variables (evapotranspiration, snow cover, and soil moisture). Depending on the region, the persistence from spring to summer of soil moisture or snow anomalies generated during spring by temperature and precipitation variations may explain river flows variations in summer, when no concomitant climate variations exist.

  3. Ninety-Eight Atheists: Atheism among the Non-Elite in Twentieth Century Britain

    Directory of Open Access Journals (Sweden)

    Matt Sheard


    Full Text Available Widespread atheism in the general population is one of the defining characteristics of twentieth-century British society, yet until very recently, it has largely been unregarded by historians. This study attempts to contribute to the remedy of this omission by considering autobiographies and oral histories of non-elite atheists between 1890 and 1980. It shows that atheisation (the transition from religious belief to atheism is principally a phenomenon of childhood and adolescence, with 80% of the sources becoming atheist by the age of twenty. The reasons the subjects gave for their irreligion were varied, of greatest significance were nearly two thirds who regarded religion as irrelevant to their lives, showing a lack of engagement with religion, its concepts and rituals. Many of these were from weakly religious or irreligious backgrounds who experienced ‘irreligious socialisation’, rendering religion irrelevant and contributed significantly to the progress of atheisation. Religious trauma, criticism of religion, personal trauma, radical politics, and rationalism accounted for similar proportions of reasons, and were mentioned by only 12–18% of sources. The potential influence of parental attitude to religion, other childhood experiences, religious education, reducing existential threat, historic events, and the social revolution of the 1960s are also considered as ‘unarticulated causes’ of the subjects’ irreligion.

  4. Experiments and Research Programmes. Revisiting Vitalism/Non-Vitalism Debate in Early Twentieth Century

    Directory of Open Access Journals (Sweden)



    Full Text Available Debates in the philosophy of science typically take place around issues such as realism and theory change. Recently, the debate has been reformulated to bring in the role of experiments in the context of theory change. As regards realism, Ian Hacking’s contribution has been to introduce ‘intervention’ as the basis of realism. He also proposed, following Imre Lakatos, to replace the issue of truth with progress and rationality. In this context we examine the case of the vitalism — reductionism debate in biology inspired by the works of Indian physicist-turned-biologist Jagadish Chandra Bose (1858–1937, in the early twentieth century. Both camps had their characteristic hardcores. Vitalists led by John S. Burdon-Sanderson and Augustus D. Waller accepted religious metaphysics to support their research programme, which ultimately degenerated. Bose worked more with the ideals of science such as Occam’s razor, large-scale systematization of phenomena and novel prediction. I argue that his religious metaphysics, instead of acting as a protective shield, helped him to consolidate his position and allowed further problem shift resulting in a research programme that involved consciousness too. His research programme remains relevant even today.

  5. The German genius Europe's third renaissance, the second scientific revolution, and the twentieth century

    CERN Document Server

    Watson, Peter


    Peter Watson's virtuoso sweep through modern German thought and culture, from 1750 to the present day, will challenge and confound both the stereotypes the world has of Germany and those that Germany has of itself. From the end of the Baroque era and the death of Bach to the rise of Hitler in 1933, Germany was transformed from a poor relation among Western nations into a dominant intellectual and cultural force—more creative and influential than France, Britain, Italy, Holland, and the United States. In the early decades of the twentieth century, German artists, writers, scholars, philosophers, scientists, and engineers were leading their freshly unified country to new and unimagined heights. By 1933, Germans had won more Nobel Prizes than any other nationals, and more than the British and Americans combined. Yet this remarkable genius was cut down in its prime by Adolf Hitler and his disastrous Third Reich—a brutal legacy that has overshadowed the nation's achievements ever since. How did the Germans t...

  6. Creeping, drinking, dying: the cinematic portal and the microscopic world of the twentieth-century cell. (United States)

    Landecker, Hannah


    Film scholars have long posed the question of the specificity of the film medium and the apparatus of cinema, asking what is unique to cinema, how it constrains and enables filmmakers and audiences in particular ways that other media do not. This question has rarely been considered in relation to scientific film, and here it is posed within the specific context of cell biology: What does the use oftime-based media such as film coupled with the microscope allow scientists to experience that other visualization practices do not? Examining three episodes in the twentieth-century study of the cell, this article argues that the apparatus ofmicrocinematography constitutes what might be thought of as a technical portal to another world, a door that determines the experience of the world that lies on the other side of it. In this case, the design of apparatuses to capture time-lapsed images enabled the acceleration of cellular time, bringing it into the realm of human perception and experience. Further, the experience of the cellular temporal world was part of a distinct kind of cell biology, one that was focused on behavior rather than structure, focused on the relation between cells, and between the cell and its milieu rather than on cell-intrinsic features such as chromosomes or organelles. As such, the instruments and technical design of the microcinematographic apparatus may be understood as a kind of materialized epistemology, the history of which can elucidate how cinema was and is used to produce scientific knowledge.

  7. Potentially induced earthquakes during the early twentieth century in the Los Angeles Basin (United States)

    Hough, Susan E.; Page, Morgan T.


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

  8. Metal Construction Toys of the Early Twentieth Century: Their Astronomical Applications (United States)

    Rumstay, K. S.


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

  9. Comparing early twentieth century and present-day atmospheric pollution in SW France: A story of lichens. (United States)

    Agnan, Y; Séjalon-Delmas, N; Probst, A


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

  10. Analysis of the projected regional sea-ice changes in the Southern Ocean during the twenty-first century

    Energy Technology Data Exchange (ETDEWEB)

    Lefebvre, W.; Goosse, H. [Universite Catholique de Louvain, Institut d' Astronomie et de Geophysique Georges Lemaitre, Louvain-la-Neuve (Belgium)


    Using the set of simulations performed with atmosphere-ocean general circulation models (AOGCMs) for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4), the projected regional distribution of sea ice for the twenty-first century has been investigated. Averaged over all those model simulations, the current climate is reasonably well reproduced. However, this averaging procedure hides the errors from individual models. Over the twentieth century, the multimodel average simulates a larger sea-ice concentration decrease around the Antarctic Peninsula compared to other regions, which is in qualitative agreement with observations. This is likely related to the positive trend in the Southern Annular Mode (SAM) index over the twentieth century, in both observations and in the multimodel average. Despite the simulated positive future trend in SAM, such a regional feature around the Antarctic Peninsula is absent in the projected sea-ice change for the end of the twenty-first century. The maximum decrease is indeed located over the central Weddell Sea and the Amundsen-Bellingshausen Seas. In most models, changes in the oceanic currents could play a role in the regional distribution of the sea ice, especially in the Ross Sea, where stronger southward currents could be responsible for a smaller sea-ice decrease during the twenty-first century. Finally, changes in the mixed layer depth can be found in some models, inducing locally strong changes in the sea-ice concentration. (orig.)

  11. Some doctors of medicine who published optometry books and played significant roles in early twentieth century optometric education. (United States)

    Goss, David A


    This paper provides brief profiles of four doctors of medicine who wrote books for optometrists and who were faculty members in, and/or directors of, optometry schools in the early twentieth century. Those studied were Thomas G. Atkinson (1870-1946), Marshall B. Ketchum (1856-1937), Joseph I. Pascal (1890-1955), and Clarence W. Talbot (1883-1958). The content of the books they wrote is also discussed.

    Full Text Available Based on the concern that abandoned and vulnerable children represented for governmental and intellectual elites in Argentina in the late nineteenth and early twentieth centuries, this paper analyses the vicissitudes around installation of a Patronato de Menores in the province of Buenos Aires. The article pays special attention to the relationship between budgetary issues and the political dimension, which colored parliamentary debate. I maintain that political centralization and the question of municipal autonomy crossed over into the debate surrounding children.

    Full Text Available The definition of a policy of national defense and internal security in democracy, created conditions to advance in the process of restructuring of the Argentina Navy, introducing changes in its organization and functions. In this article we will focus this process analyzing, on the one hand, the relationship between the definitions of defense policy and the configuration of naval military instrument between the end of the twentieth century and early twenty-first century; and, on the other hand, understanding their development in the case of two components of the force: the marine corps and the division of maritime patrol.

  14. The Role of Degeneration Theory in the Understanding of Mental Illness, Colombia First Half of the Twentieth Century

    Directory of Open Access Journals (Sweden)

    María Fernanda Vásquez Valencia


    Full Text Available Based on medical journals and theses from the first half of the twentieth century, this article analyzes the role played by the theory of degeneration in the understanding of mental illness in Colombia. It is particularly interesting to show how Colombian physicians have appropriated concepts such as degeneration, diathesis, morbid heredity and stigmas of degeneration since the early 20th century to describe, classify and define mental illnesses present in Colombian territory. During this period the theory of degeneration served as the conceptual and theoretical framework for understanding the etiology, genesis and evolution of mental illness.

  15. Women, work and health between the nineteenth and twentieth centuries from a national and international perspective. (United States)

    Salerno, Silvana


    A few years after a series of meetings of Italian scientists were convened prior to the unification of Italy, the first women qualified in medicine and other dedicated women participated in founding a movement for the improvement of living and working conditions of women and children in Italy. analysis of Italian women's contributions in the proceedings of the International Council of Women Congresses and their impact on increasing the number of women's occupational health studies presented at the fourth National Congress on Occupational Diseases held in Rome in 1914. Analysis of the proceedings of the International Council of Women Congresses (Washington, Chicago, London), and of the Women's National Council and other documents so as to obtain a picture of Italian women's working conditions at that time. Women and children worked an excessive number of hours per day, were underpaid, and had a legal status of inferiority. The main work sectors were sewing, embroidery, lace making, ironing, cooking, washing, dressmaking, millinery, fashion design, typing, weaving, artificial flowers, etc. The same sort of work was available to Italian women who emigrated to the United States of America. The success achieved by the women's movement is shown in the paper presented by Irene de Bonis "Occupational diseases among women" and published in the proceedings of the fourth National Congress on Occupational Diseases held in Rome, 9-14 June 1914. The article outlines the main features of the women's movement at the turn of the twentieth century, focussing on their publications describing Italian women's working conditions, considered in an international context. The movement's engagement in the promotion of women's occupational health at international and national level was successful but the First World War was to transform this achievement into the women's peace movement.

  16. Radioactivity in the twentieth century and some of its implications for the third millennium

    International Nuclear Information System (INIS)

    Paschoa, Anselmo S.


    Radioactivity has always been present in the Earth, as well in the Universe at large. However, the discovery of the phenomenon of radioactivity occurred just over 100 years ago. It is well known today that nuclear processes are directly related to the nucleosynthesis in starts. As a matter of fact, all types of nuclear reactions, like fission and captures, occur in stars at different stages of stellar evolution. The sequence of episodes that took place between 1896 and 1898, involving Henry Becquerel, and Marie and Pierre Curie, led to the discover of the phenomena that would greatly influence the twentieth century. It took, however, until 1939 for the phenomenon of fission to be explained by Otto Frish and Lise Meitner, based on experimental results obtained earlier by Otto Hahn and Fritz Strassman. Aware of the potential military implications of fission Leo Szilard exhorted Albert Einstein to write a letter to the President of the United States, Franklin Delano Roosevelt. Such letter is regarded as the initial step of the mammoth Manhattan Project to build the first nuclear weapons. The aftermath of nuclear attacks to Japan, at the end of the Second World War, created dramatic changes in the relations among the nations. The escalation of the nuclear arsenals throughout the world created peculiar and secretive that, by and large, produced wastes of many kinds and a variety of radioactive concentrations which were held by the governments and/or the military industries themselves. The paper will discuss some possible international cooperative efforts to reduce some of the deleterious implications for the third millennium of the inheritance left behind by the military nuclear programs.

  17. History and development of Carboniferous palynology in North America during the early and middle twentieth century

    Energy Technology Data Exchange (ETDEWEB)

    Cross, A.T.; Kosanke, R.M. [Michigan State University, East Lansing, MI (United States). Dept. of Geological Sciences


    Three main roots of upper Palaeozoic palynology in North America date from the opening of the twentieth century. These are Gresley`s recognition of spores in Iowa coal balls in 1901, analyses of spores by Sellards from Mazon Creek compressions in 1902, and Thiessen`s analyses of dispersed spores from coal maceration and thin sections in 1913. The Pollen Analysis Circular brought workers into contact in the 1940s and generated interest in older fossils. The Paleobotanical Section of the Botanical Society of America (1936) and the Coal Geology Division of the Geological Society of America (1955) encouraged palynologists to participate in meetings and field trips. Fundamental papers by Schopf et al. in 1944 and Kosanke in 1950 established Carboniferous palynology in North America. Active teaching and research centers at the University of Chicago in the 1920s and the University of Illinois and Coe College in the 1930s spawned new palynological centers, particularly throughout the Midwest. Palynological contributions on dispersed spores, mainly from coals and associated rocks, appeared from educational centers from 1929 through the 1950s. Limited reviews of early researches at early palynologic centers are here included by region. Palynology applied to petroleum exploration appeared in the 1940s and major petroleum companies had palynology laboratories in place by 1960. The first international palynology journals appeared in the 1950s and catalogs first appeared in the mid-1960s, except the Catalog of Fossil Spores and Pollen, which began in 1957. The first specific palynology organization, the American Association of Stratigraphic Palynologisst, was founded in 1968. 304 refs., 38 figs

    Following the petroleum price and supply disruptions of 1973, the U.S. government began a substantial program to fund the development of alternative fuels. Direct coal liquefaction was one of the potential routes to alternative fuels. The direct coal liquefaction program was funded at substantial levels through 1982, and at much lower levels thereafter. Those processes that were of most interest during this period were designed to produce primarily distillate fuels. By 1999, U.S. government funding for the development of direct coal liquefaction ended. Now that the end of this campaign has arrived, it is appropriate to summarize the process learnings derived from it. This report is a summary of the process learnings derived from the DOE direct coal liquefaction process development campaign of the late twentieth century. The report concentrates on those process development programs that were designed to produce primarily distillate fuels and were largely funded by DOE and its predecessors in response to the petroleum supply and price disruptions of the 1970s. The report is structured as chapters written by different authors on most of the major individual DOE-funded process development programs. The focus of the report is process learnings, as opposed to, say, fundamental coal liquefaction science or equipment design. As detailed in the overview (Chapter 2), DOE's direct coal liquefaction campaign made substantial progress in improving the process yields and the quality of the distillate product. Much of the progress was made after termination by 1983 of the major demonstration programs of the ''first generation'' (SRC-II, H-Coal, EDS) processes

  19. Vagabond Figures in Slovenian Visual Art and Literature at the Beginning of the Twentieth Century

    Directory of Open Access Journals (Sweden)

    Robert Simonišek


    Full Text Available The article explores the relationship between visual and literary motifs in Slovenian painting (and illustration, graphics, and drawing and literature (both prose and poetry at the beginning of the twentieth century. It uses examples to show the popularity and rich variety of vagabond figures and their transformations and reciprocity at the level of the painting/text. However, a distinctive feature of this article is that it places the subject within the context of hermeneutics, a method that has not been used in Slovenian art history. In addition, it also reveals the symbolic complexity of the vagabond figure in the context of writers, other works, and social-historical circumstances. The emphasis is placed on artists that showed enthusiasm for this figure as a subject during the Belle Époque and also those that followed the very popular bohemian lifestyle in their everyday lives. The reception of Slovenian folk and traditional motifs from the past produced visual and semantic oscillation in which the phenomena of vagabond figures were systematized and interpreted. Many painters (e.g., Gvidon Birolla, and Maksim Gaspari and writers (e.g., Oton Župančič, Cvetko Golar, and Ivan Cankar clung to the Slovenian tradition with romantic overtones and, in line with their artistic atmosphere, integrated vagabond figures into typical Slovenian landscapes or environments. Some of them followed Symbolism and modernized the figures with autobiographical references (e.g., Fran Tratnik. The situation among the youngest generation of artists in particular showed that they managed to “escape” from copying traditional motifs and instead used them in a modern form in the “here and now” (e.g., Ivan Cankar. The discrepancy between the lack of the vagabond theme in oil painting and strong diversification in illustration, drawing, graphics, and literature could be explained by consumers’ perceived difference between “high” and “popular” art.

  20. Bruised witness: Bernard Spilsbury and the performance of early twentieth-century English forensic pathology. (United States)

    Burney, Ian; Pemberton, Neil


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

  1. Biography of a technology: North America's power grid through the twentieth century (United States)

    Cohn, Julie A.

    North Americans are among the world's most intense consumers of electricity. The vast majority in the United States and Canada access power from a network of transmission lines that stretch from the East Coast to the West Coast and from Canada to the Mexican Baja. This network, known as the largest interconnected machine in the world, evolved during the first two thirds of the twentieth century. With the very first link-ups occurring at the end of the 1890s, a wide variety of public and private utilities extended power lines to reach markets, access and manage energy resources, balance loads, realize economies of scale, provide backup power, and achieve economic stability. In 1967, utility managers and the Bureau of Reclamation connected the expansive eastern and western power pools to create the North American grid. Unlike other power grids around the world, built by single, centrally controlled entities, this large technological system emerged as the result of multiple decisions across eighty-five years of development, and negotiations for control at the economic, political, and technological levels. This dissertation describes the process of building the North American grid and the paradoxes the resulting system represents. While the grid functions as a single machine moving electricity across the continent, it is owned by many independent entities. Smooth operations suggest that the grid is a unified system; however, it operates under shared management and divided authority. In addition, although a single power network seems the logical outcome of electrification, in fact it was assembled through aggregation, not planning. Interconnections intentionally increase the robustness of individual sub-networks, yet the system itself is fragile, as demonstrated by major cascading power outages. Finally, the transmission network facilitates increased use of energy resources and consumption of power, but at certain points in the past, it also served as a technology of

  2. Balkans as a cultural symbol in the Serbian music of the first half of the twentieth century

    Directory of Open Access Journals (Sweden)

    Milanović Biljana


    Full Text Available Focus on the internalization of Western images in the Balkans has special significance in researching Serbian art. The functioning of Balkanism as it overlapped and intersected with Orientalism is indicated in the text by an examination of the cases of Petar Konjović, Miloje Milojević and Josip Slavenski, the three significant composers working in Serbia during the first half of the twentieth century. Their modernistic projects present different metaphors of the Balkans. Nevertheless each of them is marked by desire to change the Balkan image into a 'positive' one and thus stands as a special voice for Serbian and regional placing in European competition for musical spaces.

  3. Maintaining Masculinity in Mid-Twentieth-Century American Psychology: Edwin Boring, Scientific Eminence, and the "Woman Problem". (United States)

    Rutherford, Alexandra


    Using mid-twentieth-century American psychology as my focus, I explore how scientific psychology was constructed as a distinctly masculine enterprise and was navigated by those who did not conform easily to this masculine ideal. I show how women emerged as problems for science through the vigorous gatekeeping activities and personal and professional writings of disciplinary figurehead Edwin G. Boring. I trace Boring's intellectual and professional socialization into masculine science and his efforts to understand women's apparent lack of scientific eminence, efforts that were clearly undergirded by preexisting and widely shared assumptions about men's and women's capacities and preferences.

  4. [The medical, social and institutional challenges resulting from poliomyelitis: comprehensive rehabilitation in Argentina in the mid-twentieth century]. (United States)

    Alvarez, Adriana


    Poliomyelitis on an epidemic scale gave rise to several challenges, one of which was the rehabilitation from the after-effects on many of the people who suffered from the disease. Paralysis and the ways it transformed the concept of physical rehabilitation (where the objective was only to restore the mobility of the affected muscles) and comprehensive rehabilitation that included social, educational and professional aspects in Argentina in the mid-twentieth century are the themes addressed in this article. It uses the methodology of institutional history that interacts in an ongoing manner with the history of health and disease.

  5. The return of the phoenix: the 1963 International Congress of Zoology and American zoologists in the twentieth century. (United States)

    Johnson, Kristin


    This paper examines the International Congress of Zoology held in Washington D.C. in 1963 as a portrait of American zoologists' search for effective and rewarding relationships with both each other and the public. Organizers of the congress envisioned the congress as a last ditch effort to unify the disparate subdisciplines of zoology, overcome the barriers of specialization, and ward off the heady claims of more reductionist biologists. The problems zoologists faced as they worked to fulfill these ambitious goals illuminate some of the challenges faced by members of the naturalist tradition as they worked to establish disciplinary unity while seeking public support in the competitive world of twentieth century science.

  8. The other woman and her child: extra-marital affairs and illegitimacy in twentieth-century Britain. (United States)

    Evans, Tanya Evans


    This article investigates the numbers of 'other women' and their children up until the 1960s in Britain. It analyses 'irregular and illicit unions' in the records of the National Council for the Unmarried Mother and her Child (now One Parent Families/Gingerbread), and explores evidence on these unions in the debates over the passage of the Divorce Acts of 1923 and 1937 as well as the Legitimacy Acts of 1926 and 1959. It suggests that the prevalence of illicit unions throughout the twentieth century and before allows us to question contemporary concerns about our supposed 'divorcing society' and the decline of family life in modern Britain.

  9. A historical perspective on the development of modern concepts of tissue perfusion: prehistory to the twentieth century. (United States)

    Ashby, Nathan; Squiers, Joshua


    The historical development of the concept of perfusion is traced, with particular focus on the development of the modern clinical concepts of perfusion through the fields of anatomy, physiology, and biochemistry. This article reviews many of the significant contributors to the changing ideas of perfusion up through the twentieth century that have influenced the modern physiologic circulatory and metabolic models. The developments outlined have provided the modern model of perfusion, linking the cardiopulmonary circulation, tissue oxygen utilization and carbon dioxide production, food intake, tissue waste production and elimination, and ultimately the production and utilization of ATP in the body.

  10. The Strategic Petroleum Reserve: United States energy security, oil politics, and petroleum reserves policies in the twentieth century (United States)

    Beaubouef, Bruce Andre

    The history of U.S. petroleum reserves policies in the twentieth century, including the Strategic Petroleum Reserve (SPR) program, provides a case study of the economic and political aspects of national security, and shows the ways in which the American political economy influences national security. One key problem plagued federal petroleum reserve programs and proposals throughout the twentieth century. In a political economy which traditionally placed strong emphasis upon the sanctity of private property and free markets, could the government develop an emergency petroleum reserve policy despite opposition from the private sector? Previous literature on the SPR and oil-stockpiling programs has largely disregarded the historical perspective, focusing instead upon econometric models, suggesting future oil-stockpiling policy options. This study will also make conclusions about the future of governmental oil-stockpiling policies, particularly with regard to the SPR program, but it will do so informed by a systematic history of the emergency petroleum reserve impulse in the twentieth century. Through a study of the emergency petroleum reserve impulse, one can see how the American political economy of oil and energy changed over the twentieth century. As petroleum became crucial to the military and then economic security of the United States, the federal government sought to develop emergency petroleum reserves first for the military, then for the civilian economy. But while the American petroleum industry could deliver the energy "goods" to American energy consumers at a reasonable price, the companies reigned supreme in the political equation. While that was true, federal petroleum reserve programs and proposals conflicted with and were overwhelmed by the historic American tradition of individual economic and private property rights. The depletion of American petroleum reserves changed that political equation, and the ensuing energy crises of the 1970s not only

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

  12. Exploring Changes in Nitrogen and Phosphorus Retention in Global Rivers in the Twentieth Century (United States)

    Beusen, A.; Bouwman, L.; Van Beek, R.; Wisser, D.; Hartmann, J.


    Nutrients are transported from land to sea through the continuum formed by components of river basins (soils, groundwater, riparian zones, streams, rivers, lakes, and reservoirs). The hydrology, ecology and biogeochemical processing in each of these components are strongly coupled and result in retention of a significant fraction of the nutrients transported. For analyzing the impact of multiple changes and disturbances at the global scale, we use a distributed approach to describe the nitrogen (N) and phosphorus (P) transport and retention in all the above river basin components. A hydrological model is used to describe the water flow through the respective compartments. We analyze the changes in retention during the past century (1900-2000), as this period encompasses dramatic increases in human population and economic human activities that have resulted in global changes, such as climate change, land use change, changes in the hydrology by dam construction, irrigation, and consumptive water use. In the period 1900-2000, the global soil N budget surplus (inputs minus withdrawal by plants) for agricultural and natural ecosystems increased from 118 to 202 Tg yr-1, and the global P budget increased from nutrient spiraling concept. We concentrate on the flows of total N and total P, because of the importance of the ratios between these two elements for biogeochemistry and the functioning of aquatic ecosystems. Since the various processes in the different compartments in terms of delivery to surface water are poorly known, we present a sensitivity analysis of the modeled river export for a number of key variables.

  13. Italian news coverage of radiation in the early decades of the twentieth century: A qualitative and quantitative analysis. (United States)

    Candela, Andrea; Pasquarè Mariotto, Federico


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

  14. Working-Class Ideas and Experiences of Sexuality in Twentieth-Century Britain: Regionalism as a Category of Analysis. (United States)

    Smith, Helen


    This article will explore region as a category of analysis for understanding gender, sexual cultures, and the expression of same-sex desire. In unpicking the notion of regional difference in both its tangible and intangible forms, it outlines the corresponding impact on how sexual cultures developed and were experienced in twentieth-century Britain. By recognizing that the area in which an individual lived could have as much impact on their sense of self and their sexual experiences as issues of race, gender, and class, a new and fruitful avenue of interpretation is opened up for the history of sexuality and twentieth-century British history more broadly. Such a methodology has the potential to add a new dimension to all histories of non-state-sanctioned sexual experience such as illegitimacy, premarital sex, extramarital affairs, and prostitution. In using regional case studies and interrogating ideas of sexual taboo, this article offers a unique interpretation of sexual experience that destabilizes current London-centric narratives and offers a more democratic and nuanced history of sex.

  15. Has psychology "found its true path"? Methods, objectivity, and cries of "crisis" in early twentieth-century French psychology. (United States)

    Carson, John


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

  16. Multi-year climate variability in the Southwestern United States within a context of a dynamically downscaled twentieth century reanalysis (United States)

    Carrillo, Carlos M.; Castro, Christopher L.; Chang, Hsin-I.; Luong, Thang M.


    This investigation evaluates whether there is coherency in warm and cool season precipitation at the low-frequency scale that may be responsible for multi-year droughts in the US Southwest. This low-frequency climate variability at the decadal scale and longer is studied within the context of a twentieth-century reanalysis (20CR) and its dynamically-downscaled version (DD-20CR). A spectral domain matrix methods technique (Multiple-Taper-Method Singular Value Decomposition) is applied to these datasets to identify statistically significant spatiotemporal precipitation patterns for the cool (November-April) and warm (July-August) seasons. The low-frequency variability in the 20CR is evaluated by exploring global to continental-scale spatiotemporal variability in moisture flux convergence (MFC) to the occurrence of multiyear droughts and pluvials in Central America, as this region has a demonstrated anti-phase relationship in low-frequency climate variability with northern Mexico and the southwestern US By using the MFC in lieu of precipitation, this study reveals that the 20CR is able to resolve well the low-frequency, multiyear climate variability. In the context of the DD-20CR, multiyear droughts and pluvials in the southwestern US (in the early twentieth century) are significantly related to this low-frequency climate variability. The precipitation anomalies at these low-frequency timescales are in phase between the cool and warm seasons, consistent with the concept of dual-season drought as has been suggested in tree ring studies.

  17. An assemblage of science and home. The gendered lifestyle of Svante Arrhenius and early twentieth-century physical chemistry. (United States)

    Bergwik, Staffan


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

  18. Sound Objects and Sound Products: Standardizing a New Culture of Listening in the First Half of the Twentieth Century

    Directory of Open Access Journals (Sweden)

    Alexandra Hui


    Full Text Available In this chapter I develop the psychological underpinnings of environmental music towards an understanding of how the goals of cognitive and behavioral psycholo-gists contributed to a new kind of listening at the beginning of the twentieth century. I begin with an examination of nineteenth-century concerns about both the physical and psychological effects of music and fraught debate among experi-mental psychologists of the role of musical expertise in the laboratory. These con-cerns were, I argue, rooted in the assumption of a direct, corporeal connection between the generation and reception of music, usually bound within a single, individual body. In the twentieth century, new technology liberated the listener from a temporally- and geographically-bound experience of music. The Tone Tests, Re-Creation Recitals, and Mood Change “parties” of Thomas Edison and the psychologist Walter Bingham show that recording technology allowed for a normalization and standardization of listening not previously possible in the music halls and laboratories of the nineteenth century. Rather paradoxically, since it also made music more accessible to the individual listener, recorded music, mobilized by industrial psychologists and record companies alike, created a new sound experience actively designed for the lowest common denominator of mass listen-ing. It also contributed to the cultivation of a new practice of mass listening. The new mass listening practice presents broader questions about the definition of music and its functional role – If the function of music is to be ignored, is it still music?

    Directory of Open Access Journals (Sweden)

    Hugo de Carvalho Quinta


    Full Text Available This article aims to discuss the beginning of criminology in Argentina in the late nineteenth century and early twentieth century, to understand how it was articulated during the nation-state building process. To achieve this purpose, a state project reflection unfolded in criminological perspective that is based on legal positivism of the period was made. The country was forefront in interest in criminology in that some intellectuals jurists published numerous articles on the crime studies in the first criminology journal of Argentina, Criminalogia Moderna magazine, founded in 1898 and directed by the teacher, lawyer and intellectual Italian, Pietro Gori. The influence of European sociological perspective in Argentina criminology can be seen from a literature review. The examination of some articles published in the journal indicates how criminology introduced in Europe grounds the buenosairean intellectuality. Some authors have linked criminology with social phenomena of a nation increasingly industrialized, proletarianized, politicized and urbanized.

    Directory of Open Access Journals (Sweden)

    Jasna Potočnik Topler


    Full Text Available Norman Mailer, one of the most influential authors of the second half of the twentieth century, faithfully followed his principle that a writer should alsobe a critic of contemporary reality. Therefore, most of his works portray the reality of the United States of America and the complexities of the contemporary American scene. Mailer described the spirit of his time - from the terror of war and numerous dynamic social and political processes to the 1969 moon landing. Conflicts were often in the centre of his writing, as was the relationship between an individual and the society; he speaks of politicalpower and the dangerous power of capital, while pointing to the threat of totalitarianism in America. Mailer spent his entire career writing about violence, power, perverted sexuality, the phenomenon of Hitler, terrorism, religion and corruption. He continually pointed out that individuals were in constant danger of losing freedom and dignity.

    Pietro Pisano


    Full Text Available From the study of articles published in Colombian magazines (particularly Cromos magazine in the second half of the twentieth century, this article proposes the analysis of some representations about upward mobility of black people. Consideration is given to the stories of some characters at different times: the judge Jose Antonio Camacho, the boxer Kid Pambelé, the model Laura Mosquera and the pianist Teresa Gómez. Although they emerged in different professional contexts, narratives about their paths have in common the emphasis on how the class representations articulated with the race and gender ones and were used to show the difficulty for a black person to be inserted in a social context different from the popular sectors, showing both their alleged incompatibility with the values of the middle class as well as the inability to fully integrate into a society dominated by whites.

  5. Contributions to a historical review of biological anthropology in Brazil from the second half of the twentieth century

    Directory of Open Access Journals (Sweden)

    Verlan Valle Gaspar Neto

    Full Text Available Abstract This article provides a preliminary historical survey of Brazilian biological anthropology from the second half of the twentieth century. Even today, little historiographic information on the last 50 or 60 years is available and/or has been explored, while few allusions to bioanthropology can be found in existing works on the history and contemporary state of anthropology in Brazil; this article attempts to span this gap. The first section examines various aspects of the general development of biological anthropology as it radiated from the centers (Europe and the United States outward over time. This initial survey affords a clearer understanding of the Brazilian case, which is the topic of the second section. This is followed by a brief historical and bibliographic account of the most recent state of biological anthropology in the country, including a number of specialized areas of research. The article concludes with a short discussion of the material covered.

  6. Freedom to divorce or protection of marriage? The divorce laws in Denmark, Norway, and Sweden in the early twentieth century. (United States)

    Le Bouteillec, Nathalie; Bersbo, Zara; Festy, Patrick


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

  7. Planning ideology and geographic thought in the early twentieth century: Charles Whitnall's progressive era park designs for socialist Milwaukee. (United States)

    Platt, Lorne A


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

  8. Techniques for nothingness: Debate over the comparability of hypnosis and Zen in early-twentieth-century Japan. (United States)

    Wu, Yu-Chuan


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

  9. Traveling with faith: the creation of women's immigrant aid associations in nineteenth and twentieth-century France. (United States)

    Machen, Emily


    This article explores the efforts of French Catholic, Protestant, and Jewish women to morally, spiritually, and physically protect immigrant and migrant women and girls in the late nineteenth and early twentieth centuries. Women of faith worried about the dangers posed by the white slave trade, and they feared the loss of spiritual consciousness among women living far from their families and their places of worship. In response to these concerns, they developed numerous faith-based international organizations aimed at protecting vulnerable working-class immigrants. Upper-class women's work in immigrant aid societies allowed them to take on much greater social and religious leadership roles than they had in the past. Likewise, the intricate, international networks that these women developed contributed to the building of international cooperation throughout Europe.

  10. The limited effect of increasing educational attainment on childlessness trends in twentieth-century Europe, women born 1916–65 (United States)

    Beaujouan, Eva; Brzozowska, Zuzanna; Zeman, Kryštof


    During the twentieth century, trends in childlessness varied strongly across European countries while educational attainment grew continuously across them. Using census and large-scale survey data from 13 European countries, we investigated the relationship between these two factors among women born between 1916 and 1965. Up to the 1940 birth cohort, the share of women childless at age 40+ decreased universally. Afterwards, the trends diverged across countries. The results suggest that the overall trends were related mainly to changing rates of childlessness within educational groups and only marginally to changes in the educational composition of the population. Over time, childlessness levels of the medium-educated and high-educated became closer to those of the low-educated, but the difference in level between the two better educated groups remained stable in Western and Southern Europe and increased slightly in the East.

  11. Crisis, change and creativity in science and technology: chemistry in the aftermath of twentieth-century global wars. (United States)

    Johnson, Jeffrey Allan


    This paper presents the organising ideas behind the symposium "Chemistry in the Aftermath of World Wars," held at the 23rd International Congress of History of Science and Technology, Budapest, 2009, whose theme was "Ideas and Instruments in Social Context." After first recounting the origins of the notion of "crisis" as a decisive turning point in general history as well as in the history of science, the paper presents war and its aftermath as a form of crisis that may affect science and technology, including chemistry, in a variety of contexts and leading to a variety of types of change. The twentieth-century world wars were exemplary forms of crisis, whose aftermaths shaped the contexts for decisive changes in modern chemistry, which continue to offer challenging opportunities for historical research. In discussing these, the paper cites selected current literature and briefly describes how the individual papers of the symposium, including the three papers published in this volume, approached these challenges.

  12. Charles Darwin's reputation: how it changed during the twentieth-century and how it may change again. (United States)

    Amundson, Ron


    Charles Darwin died in 1882. During the twentieth century his reputation varied through time, as the scientific foundation of evolutionary theory changed. Beginning the century as an intellectual hero, he soon became a virtual footnote as experimental approaches to evolution began to develop. As the Modern Synthesis developed his reputation began to rise again until eventually he was identified as a founding father of the Modern Synthesis itself. In the meantime, developmental approaches to evolution began to challenge certain aspects of the Modern Synthesis. Synthesis authors attempted to refute the relevance of development by methodological arguments, some of them indirectly credited to Darwin. By the end of the century, molecular genetics had given new life to development approaches to evolution, now called evo devo. This must be seen as a refutation of the aforesaid methodological arguments of the Modern Synthesis advocates. By the way, we can also see now how the historiography that credited Darwin with the Synthesis was in error. In conclusion, one more historical revision is suggested. Copyright © 2014 Elsevier Ltd.

  13. Comparing early twentieth century and present-day atmospheric pollution in SW France: A story of lichens

    International Nuclear Information System (INIS)

    Agnan, Y.; Séjalon-Delmas, N.; Probst, A.


    Lichens have long been known to be good indicators of air quality and atmospheric deposition. Xanthoria parietina was selected to investigate past (sourced from a herbarium) and present-day trace metal pollution in four sites from South-West France (close to Albi). Enrichment factors, relationships between elements and hierarchical classification indicated that the atmosphere was mainly impacted by coal combustion (as shown by As, Pb or Cd contamination) during the early twentieth century, whereas more recently, another mixture of pollutants (e.g. Sb, Sn, Pb and Cu) from local factories and car traffic has emerged. The Rare Earth Elements (REE) and other lithogenic elements indicated a higher dust content in the atmosphere in the early twentieth century and a specific lithological local signature. In addition to long-range atmospheric transport, local urban emissions had a strong impact on trace element contamination registered in lichens, particularly for contemporary data. - Highlights: ► We compared metal concentrations registered in contemporary and early 1900's lichens. ► In the past, As, Pb and Cd were enriched due to coal combustion. ► Nowadays, a new mixture of enriched contaminants (Sb, Sn, Pb and Cu) was evidenced. ► REE originated from local bedrock and proved an increased dust deposition in the past. ► Lichens recorded both local and long-range atmospheric contamination. - Using lichens registration, past (As, Pb, Cd) and recent (Sb, Sn, Cu) atmospheric pollution from local and long-range transport, as well as dust deposition, was evidenced in SW France.

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

    Engelmann, Lukas


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

  15. Illustrating phallic worship: uses of material objects and the production of sexual knowledge in eighteenth-century antiquarianism and early twentieth-century sexual science. (United States)

    Funke, Jana; Fisher, Kate; Grove, Jen; Langlands, Rebecca


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

    Full Text Available The social responsibility of organizations concept has become the subject of considerable researches, debates and commentaries especially in the second half of the last century. According to ethical principles organizations and individuals have the obligation to act in the benefit of society at large. Consequently, the social responsibility of a business is related to its duties and obligations directed towards the social welfare. The role of corporations in society and the issue of corporate social responsibility have been increasingly debated in the last century. Based on a literature review our paper seeks to describe and summarize some of the main contributions to the development of the social responsibility of organizations. The aims of our paper are to explore the evolution of the social responsibility of organization concept in the last century and to emphasize its various approaches, mostly in the business field. This historical trace identifies both similarities and differences related to social responsibility themes.

  1. A brief history of the American radium industry and its ties to the scientific community of its early Twentieth Century

    International Nuclear Information System (INIS)

    Landa, E.R.


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

  2. Industrial Growth in Araraquara and São Carlos Region in the First Decades of the Twentieth Century

    Directory of Open Access Journals (Sweden)

    Helena Carvalho De Lorenzo


    Full Text Available This article describes and analyzes the formation of the first manufacturing activities and the industrial growth in Araraquara and São Carlos region in the early twentieth century. It shows that from the development of the coffee economy in the region, were created the initial conditions for the emergence of a variety of industrial transformation activities of goods for local and regional consumption that could survive while the conditions for its operation and reproduction prevailed. However, changes in the state economy after the 1929 crisis brought deep changes in industry course in the region. Classic studies on the industry origin in São Paulo are taken as reference. From a methodological point of view the research that led to this study had an exploratory and investigative nature of primary and secondary sources. The conclusions point to the cyclical nature of regional productive activities, to changes in the production cycle of the region from the 30s, and to the reasons for the survival of some companies that have managed to overcome the initial difficulties and till the XXI century are part of the regional productive structure.

  10. Sub-ice-shelf sediments record history of twentieth-century retreat of Pine Island Glacier


    Smith, J.A.; Andersen, T.J.; Shortt, M.; Gaffney, A.M.; Truffer, M.; Stanton, T.P.; Bindschadler, R.; Dutrieux, P.; Jenkins, A.; Hillenbrand, C.-D.; Ehrmann, W.; Corr, H.F.J.; Farley, N.; Crowhurst, S.; Vaughan, D.G.


    The article of record as published may be found at The West Antarctic Ice Sheet is one of the largest potential sources of rising sea levels. Over the past 40 years, glaciers flowing into the Amundsen Sea sector of the ice sheet have thinned at an accelerating rate, and several numerical models suggest that unstable and irreversible retreat of the grounding line—which marks the boundary between grounded ice and floating ice shelf—is underway.

  11. Object lessons: notes on geometry in Norman Allison Calkins’ textbook (Brazil, end of nineteenth century, beginning of twentieth century

    Directory of Open Access Journals (Sweden)

    Maria Laura Magalhães Gomes


    Full Text Available Primary object lessons, by Norman Allison Calkins, ranslated by Rui Barbosa, a book that was widely disseminated in Brazil during the final years of the 19th century and the beginning of the 20th century, presents object teaching as a general method to be used in every subject or primary school. This article analyses Calkins’ book according to its presentation of mathematical content, focusing particularly on geometry lessons. It also iscusses five features of the approach adopted by Calkins: the presentation of plane geometry before geometry in space, the several materials necessary to the teaching of geometry, the drawing lessons associated with the lessons on shape, the sequence of presentation of the contents and the relations between geometry teaching and children’s pleasure and curiosity. Comments about the utilization and circulation of Calkins’ manual in geometry teaching in Brazil are also provided.

  12. Faunal isotope records reveal trophic and nutrient dynamics in twentieth century Yellowstone grasslands. (United States)

    Fox-Dobbs, Kena; Nelson, Abigail A; Koch, Paul L; Leonard, Jennifer A


    Population sizes and movement patterns of ungulate grazers and their predators have fluctuated dramatically over the past few centuries, largely owing to overharvesting, land-use change and historic management. We used δ(13)C and δ(15)N values measured from bone collagen of historic and recent gray wolves and their potential primary prey from Yellowstone National Park to gain insight into the trophic dynamics and nutrient conditions of historic and modern grasslands. The diet of reintroduced wolves closely parallels that of the historic population. We suggest that a significant shift in faunal δ(15)N values over the past century reflects impacts of anthropogenic environmental changes on grassland ecosystems, including grazer-mediated shifts in grassland nitrogen cycle processes.

  13. "Not a very nice subject." Changing views of parasites and parasitology in the twentieth century. (United States)

    Vickerman, Keith


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

  14. Glacier variability in the conterminous United States during the twentieth century (United States)

    McCabe, Gregory J.; Fountain, Andrew G.


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

  15. From Halsted to prevention and beyond: advances in the management of breast cancer during the twentieth century. (United States)

    Fisher, B


    This commentary evaluates progress made in the treatment of breast cancer during the twentieth century. Most of the period from 1900 to 1970 was governed by the 'non-science' of anecdotalism and classical inductivism and was marked by the absence of a scientific gestalt. In keeping with the Halstedian concept that breast cancer was a local disease that spread throughout the body by contiguous extension and could be cured by more expansive surgery, the disease was treated with radical surgery. In 1950, however, a new era of enlightenment began to emerge. The awareness that there was a scientific process in which hypotheses generated from laboratory and clinical investigation could be tested by means of randomised clinical trials was a seminal advance, as were findings from studies that laid the groundwork for the modern era of steroid hormone action, including identification of oestrogen receptors. Expanding knowledge regarding tumour cell kinetics, tumour heterogeneity, and technological advances related to mammography and radiation therapy were also to play a role in making possible the advances in therapy that were subsequently to occur. In the past 30 years, as a result of laboratory and clinical investigation, the Halstedian thesis of cancer surgery was displaced by an alternative hypothesis that was supported by findings from subsequent clinical trials. A new paradigm governed surgery for breast cancer, and lumpectomy followed by radiation therapy became accepted practice. A second paradigm that governed the use of adjuvant systemic therapy arose as a result of laboratory and clinical investigation. Treating patients who were free of identifiable metastatic disease with systemic adjuvant therapy because some of them might develop distant disease in the future was a revolutionary departure from prior treatment strategy and became a new exemplar. Not only did the chemotherapy favourably alter the outcome of breast cancer patients, but the anti

    Rex Butler


    Full Text Available This paper argues for a new conception of both Australian and New Zealand art history based on their long-standing historical connection. The national histories of the art of both countries that dominated the 20th century are revealed as themselves historical, preceded and followed by non-national histories that are in effect part of a wider history of world art. The paper makes its case by looking at a number of artists whose careers cross between the two countries and at the expatriates from both countries who worked together in Europe.

    Zafeiris, Konstantinos N; Kaklamani, Stamatina


    This study aimed to delineate temporal trends and differentials of completed fertility and their relationship with some characteristics of the marriage system in specific anthropological populations of northern Greece. The analysis was based on the life history of quinquennial and decennial birth cohorts of married women born in the 20th century who reproduced solely within the settlements studied. The variables studied were: children ever born, mean age of mother at first marriage, mean age of mother at first child (live birth), mean age of mother at last child and reproductive span. The results indicated that there were significant differences in the demographic characteristics of marriage and that there was an ongoing fertility transition in the 20th century in the populations studied. The mechanism of fertility decline was connected with the gradual reduction of the mean age of the mother at last child, the parallel decrease in the mean age at childbearing and a shortening of the reproductive span. Fertility levels at all times maintained a dynamic character imposed by local cultural, economic and social structures, which, in turn, were part of broader national and international structures, in all the populations studied. A strong trend of convergence of fertility levels was observed among the populations studied.

  20. A history of the ideas of theoretical physics essays on the nineteenth and twentieth century physics

    CERN Document Server

    D’Agostino, Salvo


    This book presents a perspective on the history of theoretical physics over the past two hundreds years. It comprises essays on the history of pre-Maxwellian electrodynamics, of Maxwell's and Hertz's field theories, and of the present century's relativity and quantum physics. A common thread across the essays is the search for and the exploration of themes that influenced significant con­ ceptual changes in the great movement of ideas and experiments which heralded the emergence of theoretical physics (hereafter: TP). The fun. damental change involved the recognition of the scien­ tific validity of theoretical physics. In the second half of the nine­ teenth century, it was not easy for many physicists to understand the nature and scope of theoretical physics and of its adept, the theoreti­ cal physicist. A physicist like Ludwig Boltzmann, one of the eminent contributors to the new discipline, confessed in 1895 that, "even the formulation of this concept [of a theoretical physicist] is not entirely without...

  2. From antiquity to Olympic revival: sports and Greek national historiography (nineteenth-twentieth centuries). (United States)

    Koulouri, Christina


    This study investigates the evolution of the historiography of Greek sport from the foundation of the Greek state (1830) until 1982 and its links with Greek national history, which also took shape primarily during the nineteenth century. The gradual 'nationalisation' of sport as an element of Greek national character since antiquity corresponded to changes in perceptions of the national past reflected in historiography. The ancient Olympic Games, Byzantine contests and exercises, the competitions of the klephts and armatoloi (militia soldiers) during the Ottoman rule and the modern revival of the Olympic Games were all successively integrated in a national history of sport confirming national continuity and unity. However this particular genre of national historiography did not gain academic recognition until recently. The authors of histories of physical exercise and sport were amateurs or physical education instructors and could not ensure to their work the authority of a separate discipline.

  3. Historicizing “Korean Criminality”: Colonial Criminality in Twentieth Century Japan

    Directory of Open Access Journals (Sweden)

    Joel Matthews


    Full Text Available In the context of Japanese colonialism, this article examines the discourse of colonial criminality that came to epistemologically position the Korean colonial subject as criminal and therefore necessitating domination, surveillance and punishment. The discourse of colonial criminality stemmed from Japan's late nineteenth century epistemological commitment to imperialism and concomitant knowledge of law and the legality of colonial subjects. Through an analysis that historicizes the “criminal Korean” (futei senjin epithet in the prewar and the emergence of yami as a signifier of Korean economic criminality throughout the 1940s, this article illustrates how the racialization of Koreans in Japan was both framed in terms of crime and subversion, and how that criminality functioned as a justification for postcolonial legalized exclusion and discrimination.

  4. Clear and pregnant danger: the making of prenatal psychology in mid-twentieth-century America. (United States)

    Eisenberg, Ziv


    Despite shaky evidence, American medical literature in the twenty-first century includes assumptions about the ability of expectant women's psyche to impact their pregnancy. This essay argues that such notions are rooted in "prenatal psychology," a discursive hybrid constructed by renowned psychiatrists in the 1940s and 1950s. Benefiting from the popularity of Freudianism and from women's social status after the war, doctors like Karl Menninger, William Menninger, Helene Deutsch, and Flanders Dunbar fused traditional ideas about the power of women's emotions to influence pregnancy with trendy ego psychology and psychosomatic theories. They argued that women who experienced difficult pregnancies, threw up excessively or miscarried, suffered from a problem that had a name: neurosis. Several leading obstetricians and gynecologists embraced these ideas and helped spread them in the professional literature, urging their colleagues to use talk therapy in the care of pregnant women.

  5. From Science to Industry: The Sites of Aluminium in France from the Nineteenth to the Twentieth Century. (United States)

    Le Roux, Muriel


    This paper explores the history of the isolation and industrial production of aluminium in France, from the work of Henri Sainte-Claire Deville in the 1850s to the latter part of the twentieth century, focusing on the relationships between academic research and industrial exploitation. In particular, it identifies a culture and organisation of research and development, "learning-by-doing," that emerged in the French aluminium industry following the establishment of the first electrolytic production facilities in the late 1880s by Paul Héroult, who, along with the American Charles Hall, patented the electrolytic method of producing the metal. This French method of R&D was a product both of a scientific culture that saw a continuity between scientific research and industrial application, and of a state policy that, unlike in Germany or the United States, was late to recognise the importance of fostering, on a large scale, the relations between academic chemistry and industry. It was only after World War II that the French state came fully to recognise the importance of underpinning industry with scientific research. And it was only from the 1960s, in the face of intensifying global competition, the risks of pollution, and the cost of energy, that the major aluminium firm Pechiney et Cie was able to replace a culture of "learning-by-doing" by one that integrated fundamental science with the production process.

  6. Sex discrimination from the acetabulum in a twentieth-century skeletal sample from France using digital photogrammetry. (United States)

    Macaluso, P J


    Digital photogrammetric methods were used to collect diameter, area, and perimeter data of the acetabulum for a twentieth-century skeletal sample from France (Georges Olivier Collection, Musée de l'Homme, Paris) consisting of 46 males and 36 females. The measurements were then subjected to both discriminant function and logistic regression analyses in order to develop osteometric standards for sex assessment. Univariate discriminant functions and logistic regression equations yielded overall correct classification accuracy rates for both the left and the right acetabula ranging from 84.1% to 89.6%. The multivariate models developed in this study did not provide increased accuracy over those using only a single variable. Classification sex bias ratios ranged between 1.1% and 7.3% for the majority of models. The results of this study, therefore, demonstrate that metric analysis of acetabular size provides a highly accurate, and easily replicable, method of discriminating sex in this documented skeletal collection. The results further suggest that the addition of area and perimeter data derived from digital images may provide a more effective method of sex assessment than that offered by traditional linear measurements alone.

  7. Making Space for Red Tide: Discolored Water and the Early Twentieth Century Bayscape of Japanese Pearl Cultivation. (United States)

    Ericson, Kjell


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

  8. Il futurismo polacco nella critica letteraria dell’epoca [Polish Futurism in Literary Criticism of the Early Twentieth Century

    Directory of Open Access Journals (Sweden)

    Andrea F. De Carlo


    Full Text Available The article analyses the critical voices raised against the young poets and artists who promoted Futurism in Poland during the first half of the Twentieth century. Futurist manifestos influenced the new Polish poetry, stimulating a lively debate among intellectuals of the calibre of Stefan Żeromski and Karol Irzykowski. In general, the coeval criticism of Polish Futurism focused on three main points: the lack of originality and servile imitation of foreign literary models; the repudiation of the past and national traditions; Futurism as an expression of ideologies such as Fascism in Italy and Bolshevism in Russia. In this article, specific attention is devoted to an analysis of the essay Snobizm i postęp (Snobbery and Progress, 1923 by Żeromski. The writer, criticising Polish imitators of Russian Futurism, affirmed that Polish literature and culture, in the context of national reconstruction after three partitions of Poland, needed to maintain its natural connection with the past and at the same time, without losing its national nature, to weave some universal suggestions into the plot of purely Polish themes. The goal of this article is to reveal that Żeromski and Irzykowski’s critical stance towards the Polish Futurists, which influenced the critics of the next generation, was dictated by a shallow analysis of Futuristic works and by their inability to understand Futuristic efforts to modernise Polish art and literature.

  9. The Silwood Circle a history of ecology and the making of scientific careers in late twentieth-century Britain

    CERN Document Server

    Gay, Hannah


    This is an original and wide-ranging account of the careers of a close-knit group of highly influential ecologists working in Britain from the late 1960s onwards. The book can also be read as a history of some recent developments in ecology. One of the group, Robert May, is a past president of the Royal Society, and the author of what many see as the most important treatise in theoretical ecology of the later twentieth century. That the group flourished was due not only to May's intellectual leadership, but also to the guiding hand of T. R. E. Southwood. Southwood ended his career as Linacre Professor of Zoology at the University of Oxford, where he also served a term as Vice-Chancellor. Earlier, as a professor and director of the Silwood Park campus of Imperial College London, he brought the group together. Since it began to coalesce at Silwood it has been named here the Silwood Circle. Southwood promoted the interests of its members with the larger aim of raising the profile of ecological and environmental ...

  10. Ready, willing, and able to divorce: an economic and cultural history of divorce in twentieth-century Sweden. (United States)

    Simonsson, Per; Sandström, Glenn


    This study outlines a long history of divorce in Sweden, recognizing the importance of considering both economic and cultural factors in the analysis of marital dissolution. Following Ansley Coale, the authors examine how a framework of multiple theoretical constructs, in interaction, can be applied to the development toward mass divorce. Applying a long historical perspective, the authors argue that an analysis of gendered aspects of the interaction between culture and economics is crucial for the understanding of the rise of mass divorce. The empirical analysis finds support for a marked decrease in legal and cultural obstacles to divorce already during the first decades of the twentieth century. However, economic structures remained a severe obstacle that prohibited significant increases in divorce rate prior to World War II. It was only during the 1940s and 1960s, when cultural change was complemented by marked decreases in economic interdependence between spouses, that the divorce rate exhibited significant increases. The authors find that there are advantages to looking at the development of divorce as a history in which multiple empirical factors are examined in conjunction, recognizing that these factors played different roles during different time periods.

  11. Psyche’s Sisters: Ambivalence of Sisterhood in Twentieth-century Irish Women’s Short Stories

    Directory of Open Access Journals (Sweden)

    Ann Wan-lih Chang


    Full Text Available This paper examines and evaluates representations of problematic sisterly relationships in twentieth-century Irish women’s stories which display an emphasis on ambivalence and sibling rivalry.  The paper is based primarily on the literary output of Mary Lavin, Clare Boylan, Moy McCrory, Éilís Ní Dhuibhne, Jan Kennedy, Mary Morrissy and Claire Keegan.  The paper seeks, by reference both to feminist studies and Irish women’s short stories, to demonstrate the consequences and causes of a divided sisterhood which itself may be traced back to a suppression of expression of female solidarity embedded in western culture and manifested in western literary heritage.  Typically, such stories depict a conflict sourced in the need to develop self-identity and framed within the constraints imposed by separate social roles.  This kind of conflict results potentially in rivalry, antagonism, ambivalence, and the domination of one sibling by another.  Daughters/sisters are often depicted in these stories both as competing with each other for limited resources and also as seeking a sense of personal identity through mutual polarisation.  There are also stories into which are woven undertones of domination disguised as sisterly closeness, for which the actual motivation seems to be a repressed aspiration for intimacy.

  12. Holocaust and strategic bombing: case studies in the psychology, organization, and technology of mass killing in the twentieth century

    Energy Technology Data Exchange (ETDEWEB)

    Markusen, E.R.


    After preliminary discussion of the unprecedented scale of mass killing in the twentieth century, the threat of nuclear war, and the widespread neglect of these issues, the literature on two major types of government sanctioned mass killing is reviewed; genocide, in which a government slaughters its own citizens or subjects, and total war, in which two or more governments slaughter each other's civilian citizens or subjects. This literature review reaches two basic conclusions: (1) there is considerable inconsistency and ambiguity among definitions of genocide and total war; and (2) there is a controversy regarding how distinct or similar the two forms of mass killing actually are. A comparative historical analysis was undertaken in which the Nazi Holocaust was selected as an example of genocide, and the Allied strategic bombing campaigns during World War II were selected to exemplify total war. The two cases are compared in terms of a conceptual framework of five hypothesized facilitating factors. On the basis of this comparative analysis, four or the five hypothesized facilitating factors are found to have played important roles in both cases. The findings of the study are discussed, and their implications for the threat of nuclear holocaust are explored.

  13. Key textbooks in the development of modern american plastic surgery: the first half of the twentieth century. (United States)

    Haddock, Nicholas T; McCarthy, Joseph G


    A number of historical texts published during the first half of the twentieth century played a pivotal role in shaping and defining modern plastic surgery in the United States. Blair's Surgery and Diseases of the Mouth and Jaws (1912), John Staige Davis's Plastic Surgery: Its Principles and Practice (1919), Gillies's Plastic Surgery of the Face (1920), Fomon's Surgery of Injury and Plastic Repair (1939), Ivy's Manual of Standard Practice of Plastic and Maxillofacial Surgery, Military Surgery Manuals (1943), Padgett and Stephenson's Plastic and Reconstructive Surgery (1948), and Kazanjian and Converse's The Surgical Treatment of Facial Injuries (1949) were reviewed. These texts were published at a time when plastic surgery was developing as a distinct specialty. Each work represents a different point in this evolution. All were not inclusive of all of plastic surgery, but all had a lasting impact. Four texts were based on clinical experience from World War I; one included experience from World War II; and two included experience from both. One text became a military surgical handbook in World Wars I and II, playing an important role in care for the wounded. History has demonstrated that times of war spark medical/surgical advancements, and these wars had a dramatic impact on the development of reconstructive plastic surgery. Each of these texts documented surgical advancements and provided an intellectual platform that helped shape and create the independent discipline of plastic surgery during peacetime. For many future leaders of plastic surgery, these books served as their introduction to this new field.

  14. The "Make Love, Not War" Ape: Bonobos and Late Twentieth-Century Explanations for War and Peace. (United States)

    Weinstein, Deborah


    Why do people fight wars? Following the devastation of the Second World War, this question became particularly pressing. Postwar scholars in the human sciences, from political science to anthropology, investigated the role of human nature in the causes of war even as they debated the very meaning of human nature itself. Among the wide-ranging efforts of postwar social and behavioral scientists to explain the causes of war, research on primate aggression became a compelling approach to studying the evolution of human warfare. In contrast, primatologist Frans de Waal's popular and scientific publications on primate reconciliation emphasized the naturalness of conflict resolution and peacemaking, thereby providing a counterpoint to the pessimism of aggression research while simultaneously shoring up the logic of simian analogy. De Waal's popular books heralded the "make love, not war" bonobo as humans' evolutionary next-of-kin and contributed to raising public interest in bonobos during the late twentieth century, although the apes' popular reputation subsequently exceeded the scientific discourse about them.

  15. Anthropocene landscape change and the legacy of nineteenth- and twentieth-century mining in the Fourmile Catchment, Colorado Front Range (United States)

    Dethier, David P.; Ouimet, William B.; Murphy, Sheila F.; Kotikian, Maneh; Wicherski, Will; Samuels, Rachel M.


    Human impacts on earth surface processes and materials are fundamental to understanding the proposed Anthropocene epoch. This study examines the magnitude, distribution, and long-term context of nineteenth- and twentieth-century mining in the Fourmile Creek catchment, Colorado, coupling airborne LiDAR topographic analysis with historical documents and field studies of river banks exposed by 2013 flooding. Mining impacts represent the dominant Anthropocene landscape change for this basin. Mining activity, particularly placer operations, controls floodplain stratigraphy and waste rock piles related to mining cover >5% of hillslopes in the catchment. Total rates of surface disturbance on slopes from mining activities (prospecting, mining, and road building) exceed pre-nineteenth-century rates by at least fifty times. Recent flooding and the overprint of human impacts obscure the record of Holocene floodplain evolution. Stratigraphic relations indicate that the Fourmile valley floor was as much as two meters higher in the past 2,000 years and that placer reworking, lateral erosion, or minor downcutting dominated from the late Holocene to present. Concentrations of As and Au in the fine fraction of hillslope soil, mining-related deposits, and fluvial deposits serve as a geochemical marker of mining activity in the catchment; reducing As and Au values in floodplain sediment will take hundreds of years to millennia. Overall, the Fourmile Creek catchment provides a valuable example of Anthropocene landscape change for mountainous regions of the Western United States, where hillslope and floodplain markers of human activity vary, high rates of geomorphic processes affect mixing and preservation of marker deposits, and long-term impact varies by landscape location.

    Energy Technology Data Exchange (ETDEWEB)

    Griffiths, David J. [Reed College, Portland, OR (United States). Howard-Vollum-Professur fuer Naturwissenschaften


    Relativity theory, quantum mechanics, elementary-particle physics, and cosmology are the four pillars of modern physics. The life in the 21th century is without them no more conceivable: The special relativity theory renewed our understanding of space and time, on the laws of quantum mechanics are based countless everyday objects like transistors, computer chips, and mobile telephones; in particle accelerators we study the components oof matter, and with telescopes we take an ever deeper look in the past of the universe. Taking reference books to these themes at hand, one is overwhelmed by the plethora and complexity of the mathematical formulas. This book of the renowned professor of physics David J. Griffiths id refreshingly different. By means of many illustrative examples and entertaining stories it introducts to the themes and helps the reader also without a large mathematical apparatus to a fundamental understanding of that, about which Einstein, Schroedinger, Heisenberg, and Hubble actually thought and spoke. In each chapter numerous, pedagogically selected examples are completely worked out, in order to fill the matter with life. Moreover the text contains a manifold of problems, which allow the reader to deepen his knowledge and apply immediately. Griffith's ''Revolution in Twentieth Century Physics'' appeals not only to pupils and future studyings of natural sciences, who want to get an appetite for what lies ahead, but also to interested readers, which have already heared in the media from quarks and quanta, the curved space-time, Albert Einstein, and the big bang and now want to understandably know what is at stake in all the excitement.

  17. P A Jungian Approach to Self-fragmentation of Twentieth Century in Orwell’s Nineteen Eighty Four

    Mozhdeh Alizadeh Shirazi


    Full Text Available The problematic life of modern human has always been a significant issue for many areas of study. In reaction to the absence of romantic values and the unity of the pre-modern world, Human being was afflicted with a sense of inner crises which is referred to as self-fragmentation. Fragmentation is one of the significant features of twentieth century when a mode of anxiety subjugated both art and society. In such an atmosphere many writers of the modern century attempted to reflect in their works of literature, what they had experienced in the real world. Orwell’s Nineteen Eighty Four is one of the popular novels of Modern Era that describes a modern but fragmented society wherein the modern human’s lack of self-integration is perceptible. By representing how the protagonists respond to the voices of their psyches through characterization and dreams, which is also of crucial significance in Jung’s Analytical Psychology, Orwell explores the roots of modern human’s urge for achieving a cohesive sense of self. Accordingly, this study, attempts to illustrate how modern human steps in the path of individuation and to what extent these efforts meet with success, if any. To achieve this goal, some terms and notions of Jungian Criticism such as archetypes and the process of individuation will be borrowed, and a particular focus will be held on dreams occurring in the course of the story. In addition, this paper would like to argue that the dystopian society portrayed in these novels is the offspring of a mere rationalism which prevents human from knowing the opposing forces working within as well as the forces functioning from without.

  18. Sub-ice-shelf sediments record history of twentieth-century retreat of Pine Island Glacier. (United States)

    Smith, J A; Andersen, T J; Shortt, M; Gaffney, A M; Truffer, M; Stanton, T P; Bindschadler, R; Dutrieux, P; Jenkins, A; Hillenbrand, C-D; Ehrmann, W; Corr, H F J; Farley, N; Crowhurst, S; Vaughan, D G


    The West Antarctic Ice Sheet is one of the largest potential sources of rising sea levels. Over the past 40 years, glaciers flowing into the Amundsen Sea sector of the ice sheet have thinned at an accelerating rate, and several numerical models suggest that unstable and irreversible retreat of the grounding line-which marks the boundary between grounded ice and floating ice shelf-is underway. Understanding this recent retreat requires a detailed knowledge of grounding-line history, but the locations of the grounding line before the advent of satellite monitoring in the 1990s are poorly dated. In particular, a history of grounding-line retreat is required to understand the relative roles of contemporaneous ocean-forced change and of ongoing glacier response to an earlier perturbation in driving ice-sheet loss. Here we show that the present thinning and retreat of Pine Island Glacier in West Antarctica is part of a climatically forced trend that was triggered in the 1940s. Our conclusions arise from analysis of sediment cores recovered beneath the floating Pine Island Glacier ice shelf, and constrain the date at which the grounding line retreated from a prominent seafloor ridge. We find that incursion of marine water beyond the crest of this ridge, forming an ocean cavity beneath the ice shelf, occurred in 1945 (±12 years); final ungrounding of the ice shelf from the ridge occurred in 1970 (±4 years). The initial opening of this ocean cavity followed a period of strong warming of West Antarctica, associated with El Niño activity. Thus our results suggest that, even when climate forcing weakened, ice-sheet retreat continued.

  19. Memory Politics at Work in a Gyalrong Revolt in the Early Twentieth Century

    Tenzin Jinba


    Full Text Available A 1917 uprising led by Zöpa, a low-ranking monk who proclaimed himself emperor, attracted over four thousand participants in the Gyalrong region on the southeastern edge of the Tibetan Plateau. Some of the uprising’s agendas and goals contradicted one another. It targeted the Han with the shout of “Crush the Great Han,” even though Zöpa’s two main henchmen were Han. It evoked the support of a wider Gyalrong community and claimed to avenge Qing oppression (since the Jinchuan campaigns of the eighteenth century while attempting to establish a Qing-branded kingdom. Also, this revolt targeted foreign intrusion, as evidenced by the burning of a Catholic church in Danba. This article offers a glimpse into how this uprising was embedded in sociopolitical changes during a critical transitional period from the Qing to the Republic in Sichuan’s Sino-Tibetan borderlands. It particularly examines how memories of the Qing’s atrocities and subsequent reforms, as well as of the “golden past” of Gyalrong, catalyzed ethnic and religious tensions. Above all, this study exemplifies the significance of integrating historical analyses with ethnographic investigations by examining the ways in which written documents and oral histories constitute competing yet complementary interpretive narratives about sociopolitical changes.

    Full Text Available The end of the nineteenth century witnessed paradox among the Chinese in colonial Java. On one hand, they were prospering economically, but were nonetheless held in contempt by the Dutch, encountered legal discrimination and faced challenges if they wanted to educate their children in European schools. Their marginal position motivated them do their utmost to become “civilized subjects”, on a par with Europeans, but they were also inspired to reinvent their Chinese identity. This contribution will highlight role played by “enlightened” Chinese, the kaoem moeda bangsa Tjina. Central to this movement were the Chinese girls known to the public as bangsawan prampoewan (the noblewomen, who wrote letters the newspaper and creating a gendered public sphere. They also performed western classical music in public. Considering the inspirational impact of bangsawan prampoewan’s enlightening achievements on non-Chinese women, it is appropriate to include them into the narrative of the history of the nation’s women’s movements.

    Full Text Available A sustained progress of the town of Constanta, a predominantly commercial and touristic centre, needed the support of a modern transport infrastructure, i.e. secure and quick communication networks. This is why the development of the land transportation system, technically, as well as organizationally, turned out to be just as important as the harbour’s well known commercial shipping lanes. As such, the city was among the first towns in the country to build a connecting railway with the Danube River, once the bridges over the river were put up, and, consequently, to have a direct link with Western Europe, and the Orient Express. On the other hand, the city owes much of its progress to the local authorities, for whom the transport from town to places such as the harbour, the hippodrome, the beaches at Vii and Mamaia, were not to be neglected. Overall, this progress transformed Constanta into one of the most modern and dynamic economic areas in the Romanian Old Kingdom, in the early 20th century.

  3. Serbian music criticism in the first half of the twentieth century: Its canon, its method and its educational role

    Directory of Open Access Journals (Sweden)

    Vasić Aleksandar


    Full Text Available Serbian music criticism became a subject of professional music critics at the beginning of the twentieth century, after being developed by music amateurs throughout the whole previous century. The Serbian Literary Magazine (1901- 1914, 1920-1941, the forum of the Serbian modernist writers in the early 1900s, had a crucial role in shaping the Serbian music criticism and essayistics of the modern era. The Serbian elite musicians wrote for the SLM and therefore it reflects the most important issues of the early twentieth century Serbian music. The SLM undertook the mission of educating its readers. The music culture of the Serbian public was only recently developed. The public needed an introduction into the most important features of the European music, as well as developing its own taste in music. This paper deals with two aspects of the music criticism in the SLM, in view of its educational role: the problem of virtuosity and the method used by music critics in this magazine. The aesthetic canon of the SLM was marked by decisively negative attitude towards the virtuosity. Mainly concerned by educating the Serbian music public in the spirit of the highest music achievements in Europe, the music writers of the SLM criticized both domestic and foreign performers who favoured virtuosity over the 'essence' of music. Therefore, Niccolò Paganini, Franz Liszt, and even Peter Tchaikowsky with his Violin concerto became the subject of the magazine's criticism. However their attitude towards the interpreters with both musicality and virtuoso technique was always positive. That was evident in the writings on Jan Kubelík. This educational mission also had its effect on the structure of critique writings in the SLM. In their wish to inform the Serbian public on the European music (which they did very professionally, the critics gave much more information on biographies, bibliographies and style of the European composers, than they valued the interpretation

  4. Variability of tropical days over Greece within the second half of the twentieth century (United States)

    Nastos, P. T.; Matzarakis, A. P.


    Tropical days (TD) are defined as the days with a maximum air temperature greater than 30.0 °C. It is clear that the study of TD includes also the absolute maximum temperatures, which are of great interest for the description of a region’s climate. These days are considered as very hot, and they particularly are of great importance not only for bioclimatology and applied sciences, but also for the individuals who are sensitive in the heat-stress. The regime of the TD in Greece is the focus of this study. The aim is to demonstrate their changes from decade to decade, for the time period 1960-2000. For this study, the Annual Number of Tropical Days (ANTD) recorded by each of the 26 meteorological stations of National Meteorological Service, which are uniformly distributed in the Hellenic peninsula, was calculated and analysed. In terms of quantifying the conditions in a humanbiometeorological manner, the thermal index Physiological Equivalent Temperature (PET) and the consecutive days for Athens have been included in this study. The trends of the TD for each station were analysed through the Mann-Kendall technique, while the spatial distribution per decade reveals the regions with change (increase or decrease) in the ANTD during the examined period. Two characteristic periods of change for the ANTD appear in the majority of the meteorological stations in Greece. The first period (1955-1976) is determined by a negative trend, which is statistically significant (c.l. 95%), for adequate stations. In the period between 1976 and 2000, the increase in the ANTD and the maximum temperature exceed the corresponding maximum that appeared in the beginning of the 1950s for several of the examined meteorological stations. The human-biometeorological analysis shows that the consecutive days of PET > 35 °C have had a positive trend in the last two decades of the last century.

    Full Text Available The revolution that took place in Russia on 25 October (or, according to the new style, on 7  November 1917 is believed to have been the most important political event of the 20th century  and to have had a great influence on all aspects of life both within the country and worldwide. This  article discusses the extent to which the Russian socialist revolution affected the relatively narrow,  although extremely important, area of the mechanism for the legal regulation of labor. For this  purpose, the authors compared the concept of socialism and the practice of its implementation in  Russia with the practice of the legal regulation of labor in the countries that did not experience a  socialist revolution and therefore were considered by socialists as “bourgeois” countries. At the  same time, the authors challenged the view of the majority of Russian researchers of the Soviet period, including the researchers of the history of the legal regulation of labor, that Soviet  economic history was a process of linear progressive development (when applied to the sphere of  labor. The article shows and analyzes the dissimilarity in the qualitative characteristics of the  history of the economy and the history of the legal regulation of labor in Soviet Russia. On this  basis, the conclusions are drawn as to the influence of the Soviet experience on other countries in the sphere of the legal regulation of social labor and the relevance of this experience for the current times.

    Isabelle Brajer


    Full Text Available Eigil Rothe (active 1897-1929 is a central figure in the development of wall paintings conservation and restoration in Denmark, marking a clear departure from the practices of artist-restorers influenced by historicism. His ideas about retouching and impregnation were propelled by his sense of aesthetics, which rejected nineteenth century interpretations, and called for a respect for the passage of time. His experiments with surface treatments demonstrate unprecedented thoughts about the necessity of future treatments. His work was driven by an aspiration for the truth, as seen by his diligent photographs, such as his noteworthy documentation of the stage prior to aesthetic treatment.Eigil Rothe (actif 1897-1929 est une figure centrale dans le développement de la conservation de peintures murales et la restauration au Danemark, marquant clairement le début de pratiques nouvelles pour les restaurateurs-artiste qu’influencent l’historicisme. Ses idées relatives à la retouche et à l'imprégnation ont été soutenues par son sens esthétique, qui rejette les interprétations du dix-neuvième siècle et insiste sur le respect des marques du temps. Ses expériences relatives aux traitements de surface démontrent une conscience originale et sans précédent quant à la nécessité de traitements futurs. Son travail a toujours été motivé par une passion pour la vérité, comme le démontrent ses remarquables photographies et la documentation remarquable de l’état avant traitement.

  7. The Novarupta-Katmai eruption of 1912 - largest eruption of the twentieth century; centennial perspectives (United States)

    Hildreth, Wes; Fierstein, Judy


    The explosive outburst at Novarupta (Alaska) in June 1912 was the 20th century's most voluminous volcanic eruption. Marking its centennial, we illustrate and document the complex eruptive sequence, which was long misattributed to nearby Mount Katmai, and how its deposits have provided key insights about volcanic and magmatic processes. It was one of the few historical eruptions to produce a collapsed caldera, voluminous high-silica rhyolite, wide compositional zonation (51-78 percent SiO2), banded pumice, welded tuff, and an aerosol/dust veil that depressed global temperature measurably. It emplaced a series of ash flows that filled what became the Valley of Ten Thousand Smokes, sustaining high-temperature metal-transporting fumaroles for a decade. Three explosive episodes spanned ~60 hours, depositing ~17 km3 of fallout and 11±2 km3 of ignimbrite, together representing ~13.5 km3 of zoned magma. No observers were nearby and no aircraft were in Alaska, and so the eruption narrative was assembled from scattered villages and ship reports. Because volcanology was in its infancy and the early investigations (1915-23) were conducted under arduous expeditionary conditions, many provocative misapprehensions attended reports based on those studies. Fieldwork at Katmai was not resumed until 1953, but, since then, global advances in physical volcanology and chemical petrology have gone hand in hand with studies of the 1912 deposits, clarifying the sequence of events and processes and turning the eruption into one of the best studied in the world. To provide perspective on this century-long evolution, we describe the geologic and geographic setting of the eruption - in a remote, sparsely inhabited wilderness; we review the cultural and scientific contexts at the time of the eruption and early expeditions; and we compile a chronology of the many Katmai investigations since 1912. Products of the eruption are described in detail, including eight layers of regionwide fallout

  8. Snow contribution to springtime atmospheric predictability over the second half of the twentieth century

    Peings, Yannick [CNRM-GAME, Meteo-France et CNRS, Toulouse (France); CNRM/GMGEC/VDR, Toulouse (France); Douville, H.; Alkama, R.; Decharme, B. [CNRM-GAME, Meteo-France et CNRS, Toulouse (France)


    A set of global atmospheric simulations has been performed with the ARPEGE-Climat model in order to quantify the contribution of realistic snow conditions to seasonal atmospheric predictability in addition to that of a perfect sea surface temperature (SST) forcing. The focus is on the springtime boreal hemisphere where the combination of a significant snow cover variability and an increasing solar radiation favour the potential snow influence on the surface energy budget. The study covers the whole 1950-2000 period through the use of an original snow mass reanalysis based on an off-line land surface model and possibly constrained by satellite snow cover observations. Two ensembles of 10-member AMIP-type experiments have been first performed with relaxed versus free snow boundary conditions. The nudging towards the monthly snow mass reanalysis significantly improves both potential and actual predictability of springtime surface air temperature over Central Europe and North America. Yet, the impact is confined to the lower troposphere and there is no clear improvement in the predictability of the large-scale atmospheric circulation. Further constraining the prescribed snow boundary conditions with satellite observations does not change much the results. Finally, using the snow reanalysis only for initializing the model on March 1st also leads to a positive impact on predicted low-level temperatures but with a weaker amplitude and persistence. A conditional skill approach as well as some selected case studies provide some guidelines for interpreting these results and suggest that an underestimated snow cover variability and a misrepresentation of ENSO teleconnections may hamper the benefit of an improved snow initialization in the ARPEGE-Climat model.

  9. Women as food producers and suppliers in the twentieth century. The case of Zambia. (United States)

    Muntemba, S


    It is argued in this discussion that women's ability to produce and supply food has been deteriorating over time. Although this may have begun in precolonial times, particularly with the advent of merchant capital, 20th century economic and political developments have accelerated the process. This situation applies to peasant production as a whole, but discussion is limited to food production and supply. The discussion attempts to understand and discuss the position of women as food producers and suppliers within the framework of the social relations of production, distribution, and surplus appropriation. Land and labor issues have affected women's food production capabilities adversely, and their ability to supply food has been deteriorating. In those countries where their husbands are wage laborers, women have both fed themselves and their children and have supplemented their husbands' wages through food gifts and by maintaining them during their stay at home before the cycle begins again. Despite the fact that they could not adequately do so, men were obligated to start partially maintaining their families "back home" through cash remittances, but cash came at irregular intervals, or it was insufficient, mainly because of small wages. Some women have tried to increase their food supply capacities by going into seasonal wage labor, but often the wages are too low and the prices of food too high for this strategy to work. The time spent in wage labor could be better spent in their own production, provided the factors of production are favorable to them. The intensification of cash crop production has drawn land and labor away from food crops resulting in local food shortages. This process was realized earlier in West Africa when the colonial government started to import rice from China. Gradually, this became an acceptable food crop, but attempts to grow it in sufficient quantities have benefited only men. With the growing urban population rice became a viable

  11. How the nerves reached the muscle: Bernard Katz, Stephen W. Kuffler, and John C. Eccles-Certain implications of exile for the development of twentieth-century neurophysiology. (United States)

    Stahnisch, Frank W


    This article explores the work by Bernard Katz (1911-2003), Stephen W. Kuffler (1913-1980), and John C. Eccles (1903-1997) on the nerve-muscle junction as a milestone in twentieth-century neurophysiology with wider scientific implications. The historical question is approached from two perspectives: (a) an investigation of twentieth-century solutions to a longer physiological dispute and (b) an examination of a new kind of laboratory and academic cooperation. From this vantage point, the work pursued in Sydney by Sir John Carew Eccles' team on the neuromuscular junction is particularly valuable, since it contributed a central functional element to modern physiological understanding regarding the function and structure of the human and animal nervous system. The reflex model of neuromuscular action had already been advanced by neuroanatomists such as Georg Prochaska (1749-1820) in Bohemia since the eighteenth century. It became a major component of neurophysiological theories during the nineteenth century, based on the law associated with the names of François Magendie (1783-1855) in France and Charles Bell (1774-1842) in Britain regarding the functional differences of the sensory and motor spinal nerves. Yet, it was not until the beginning of the twentieth century that both the histological and the neurophysiological understanding of the nerve-muscle connection became entirely understood and the chemical versus electrical transmission further elicited as the mechanisms of inhibition. John C. Eccles, Bernard Katz, and Stephen W. Kuffler helped to provide some of the missing links for modern neurophysiology. The current article explores several of their scientific contributions and investigates how the context of forced migration contributed to these interactions in contingently new ways.

  12. Ranking GCM Estimates of Twentieth Century Precipitation Seasonality in the Western U.S. and its Influence on Floristic Provinces. (United States)

    Cole, K. L.; Eischeid, J. K.; Garfin, G. M.; Ironside, K.; Cobb, N. S.


    Floristic provinces of the western United States (west of 100W) can be segregated into three regions defined by significant seasonal precipitation during the months of: 1) November-March (Mediterranean); 2) July- September (Monsoonal); or, 3) May-June (Rocky Mountain). This third region is best defined by the absence of the late spring-early summer drought that affects regions 1 and 2. Each of these precipitation regimes is characterized by distinct vegetation types and fire seasonality adapted to that particular cycle of seasonal moisture availability and deficit. Further, areas where these regions blend from one to another can support even more complex seasonal patterns and resulting distinctive vegetation types. As a result, modeling the effects of climates on these ecosystems requires confidence that GCMs can at least approximate these sub- continental seasonal precipitation patterns. We evaluated the late Twentieth Century (1950-1999 AD) estimates of annual precipitation seasonality produced by 22 GCMs contained within the IPCC Fourth Assessment (AR4). These modeled estimates were compared to values from the PRISM dataset, extrapolated from station data, over the same historical period for the 3 seasonal periods defined above. The correlations between GCM estimates and PRISM values were ranked using 4 measures: 1) A map pattern relationship based on the correlation coefficient, 2) A map pattern relationship based on the congruence coefficient, 3) The ratio of simulated/observed area averaged precipitation based on the seasonal precipitation amounts, and, 4) The ratio of simulated/observed area averaged precipitation based on the seasonal precipitation percentages of the annual total. For each of the four metrics, the rank order of models was very similar. The ranked order of the performance of the different models quantified aspects of the model performance visible in the mapped results. While some models represented the seasonal patterns very well, others

  13. Between biomedical and psychological experiments: The unexpected connections between the Pasteur Institutes and the study of animal mind in the second quarter of twentieth-century France. (United States)

    Thomas, Marion


    This article explores the unexpected connections between the Pasteur Institute in French Guinea and the study of animal mind in early twentieth century France. At a time when the study of animal intelligence was thriving in France and elsewhere, apes were appealing research subjects both in psychological and biomedical studies. Drawing on two case studies (Guillaume/Meyerson and Urbain), and then, on someone responding negatively to those connections, Thétard, this article shows how the long reach of biomedicine (linked to the prestige of Bernard and Pasteur) impinged on French biology and played a role in the tortuous, if not unsuccessful fate of animal psychology in France in the second quarter of the twentieth century. It shows how attempts to use apes (and other zoo animals) to yield new insights on animal psychology faced heavy restrictions or experienced false starts, and examines the reasons why animal psychology could not properly thrive at that time in France. Beyond the supremacy of biomedical interests over psychological ones, this article additionally explains that some individuals used animal behaviour studies as steppingstones in careers in which they proceeded on to other topics. Finally, it illustrates the tension between non-academic and academic people at a time when animal psychology was trying to acquire scientific legitimacy, and also highlights the difficulties attached to the scientific study of animals in a multipurpose and hybrid environment such as the early twentieth century Parisian zoo and also the Pasteur Institute of French Guinea.

    Wöppelmann, Guy; Pouvreau, Nicolas; Simon, Bernard


    rise during the last decade compared to the global estimations of about 1.8 mm/year over longer periods (Douglas, J Geophys Res 96:6981 6992, 1991). The onset of the relatively large global sea level trends observed in the twentieth century is an important question in the science of climate change. Our findings point out to an ‘inflexion point’ at around 1890, which is remarkably close to that in 1880 found in the Liverpool record by Woodworth ( Geophys Res Lett 26:1589 1592, 1999b).

  15. The Preparation of the Diccionario biográfico obrero de Chile. Printed Culture and Working-class Sociability in the Early Twentieth Century

    Directory of Open Access Journals (Sweden)

    Juan David Murillo Sandoval


    Full Text Available Printed between 1910 and 1919, the Diccionario biográfico obrero de Chile was the first book of its kind produced in Latin America in the twentieth century. Coordinated by journalist Osvaldo López, this dictionary sought to show the trajectories of leaders and representatives of the Chilean labor world to the beginning of the century. Although this work has served as a source for many investigations, little is known about its production process, and even less about their general contents, and what they indicate about the labor elites, their self-images, objectives or print culture. Therefore, this paper seeks to contribute to the analysis of this collective biography, by rebuilding its publishing history and examining the key feature which identified the workers: sociability.

  16. Representing and Coping with Early Twentieth-Century Chongqing: “Guide Songs” as Maps, Memory Cells, and Means of Creating Cultural Imagery

    Directory of Open Access Journals (Sweden)

    Igor Chabrowski


    Full Text Available Chongqing’s “guide songs” form an interesting subgenre among the broad category of haozi 號子 (workers’ songs. These early twentieth-century songs were a form of rhythm-based oral narrative describing Chongqing’s urban spaces, river docks, and harbors. Each toponym mentioned in the lyrics was followed by a depiction of the characteristic associations, whether visible or symbolic, of the place. This article aims to analyze the verbal images of Chongqing presented in these songs in order to understand how the city was remembered, reproduced, and represented. The article deconstructs representations of the city produced by the lower classes, mainly by Sichuan boatmen, and links culturally meaningful images of urban spaces with the historical experiences of work, religion, and historical-mythical memory. It also points to the functions that oral narratives had in the urban environment of early twentieth-century Chongqing. Rhythmic and easy to remember, the songs provided ready-to-use guides and repositories of knowledge useful to anyone living or working there. A cross between utilitarian resource books and cultural representations, they shaped modes of thinking and visualizations of urban spaces and Chongqing. Finally, this article responds to the need to employ popular culture in our thinking about Chinese cities and the multiplicity of meanings they were given in pre-Communist times.

  17. Exploring the impact of agriculture on nitrogen and phosphorus biogeochemistry in global rivers during the twentieth century (Invited) (United States)

    Bouwman, L.; Beusen, A.; Van Beek, L. P.


    Nutrients are transported from land to sea through the continuum formed by soils, groundwater, riparian zones, floodplains, streams, rivers, lakes, and reservoirs. The hydrology, ecology and biogeochemical processing in each of these components are strongly coupled and result in retention of a significant fraction of the nutrients transported. This paper analyzes the global changes in nutrient biogeochemical processes and retention in rivers during the past century (1900-2000); this period encompasses dramatic increases in human population and economic human activities including agriculture that have resulted in major changes in land use, nutrient use in agriculture, wastewater flows and human interventions in the hydrology (1). We use the hydrological PCR-GLOBWB model (2) for the period 1900-2000, including climate variability and the history of dam construction and land use conversion. Global agricultural and natural N and P soil budgets for the period 1900-2000 are the starting point to simulate nutrient flows from the soil via surface runoff and leaching through the groundwater system and riparian zones. In-stream processes are described with the nutrient spiraling concept. In the period 1900-2000, the global soil N budget surplus (inputs minus withdrawal in harvested crops) for agricultural and natural ecosystems increased from 118 to 202 Tg yr-1, and the global P budget increased from nutrient delivery to streams and river nutrient export has increased rapidly in the 20th century. Model results are sensitive to factors determining the N and P delivery, as well as in-stream processes. The most uncertain factors are N delivery to streams by groundwater (denitrification as a function of thickness and reactivity of aquifers), and in-stream N and P retention parameters (net uptake velocity, retention as function of concentration).

  18. Twentieth-century atmospheric river activity along the west coasts of Europe and North America: algorithm formulation, reanalysis uncertainty and links to atmospheric circulation patterns (United States)

    Brands, S.; Gutiérrez, J. M.; San-Martín, D.


    A new atmospheric-river detection and tracking scheme based on the magnitude and direction of integrated water vapour transport is presented and applied separately over 13 regions located along the west coasts of Europe (including North Africa) and North America. Four distinct reanalyses are considered, two of which cover the entire twentieth-century: NOAA-CIRES Twentieth Century Reanalysis v2 (NOAA-20C) and ECMWF ERA-20C. Calculations are done separately for the OND and JFM-season and, for comparison with previous studies, for the ONDJFM-season as a whole. Comparing the AR-counts from NOAA-20C and ERA-20C with a running 31-year window looping through 1900-2010 reveals differences in the climatological mean and inter-annual variability which, at the start of the twentieth-century, are much more pronounced in western North America than in Europe. Correlating European AR-counts with the North Atlantic Oscillation (NAO) reveals a pattern reminiscent of the well-know precipitation dipole which is stable throughout the entire century. A similar analysis linking western North American AR-counts to the North Pacific index (NPI) is hampered by the aforementioned poor reanalysis agreement at the start of the century. During the second half of the twentieth-century, the strength of the NPI-link considerably varies with time in British Columbia and the Gulf of Alaska. Considering the period 1950-2010, AR-counts are then associated with other relevant large-scale circulation indices such as the East Atlantic, Scandinavian, Pacific-North American and West Pacific patterns (EA, SCAND, PNA and WP). Along the Atlantic coastline of the Iberian Peninsula and France, the EA-link is stronger than the NAO-link if the OND season is considered and the SCAND-link found in northern Europe is significant during both seasons. Along the west coast of North America, teleconnections are generally stronger during JFM in which case the NPI-link is significant in any of the five considered

    Simulations performed with the climate model LOVECLIM, aided with a simple data assimilation technique that forces a close matching of simulated and observed surface temperature variations, are able to reasonably reproduce the observed changes in the lower atmosphere, sea ice and ocean during the second half of the twentieth century. Although the simulated ice area slightly increases over the period 1980-2000, in agreement with observations, it decreases by 0.5 x 10{sup 6} km{sup 2} between early 1960s and early 1980s. No direct and reliable sea ice observations are available to firmly confirm this simulated decrease, but it is consistent with the data used to constrain model evolution as well as with additional independent data in both the atmosphere and the ocean. The simulated reduction of the ice area between the early 1960s and early 1980s is similar to the one simulated over that period as a response to the increase in greenhouse gas concentrations in the atmosphere while the increase in ice area over the last decades of the twentieth century is likely due to changes in atmospheric circulation. However, the exact contribution of external forcing and internal variability in the recent changes cannot be precisely estimated from our results. Our simulations also reproduce the observed oceanic subsurface warming north of the continental shelf of the Ross Sea and the salinity decrease on the Ross Sea continental shelf. Parts of those changes are likely related to the response of the system to the external forcing. Modifications in the wind pattern, influencing the ice production/melting rates, also play a role in the simulated surface salinity decrease. (orig.)

    Mustafë Haziri


    Full Text Available The historical significance of the Trepça’s mine in Stan-Terg is so big, that it is impossible to be presented in this scientific paper, because of its historic, economic and social character. This paper analyses chronologically the importance of Trepça mine, focusing with particular emphasis on the period of the twentieth century where in 1926 the first research that was implemented by the British government began. In 1930 began the modern exploitation of Trepça which was followed by some union movements which lasted until 1939. In 1941, Trepça fell into the hands of the nazi regime of Germany. Other aspects of this work include the period of the Second World War, when the nationalization of property was implemented during the communist regime in former Yugoslavia until the great strike of 1989.

  3. Love Practices in the Colombian School during the First Half of the Twentieth Century: Notes for a History of Feminine Love

    Directory of Open Access Journals (Sweden)

    Claudia Ximena Herrera Beltrán


    Full Text Available In Latin America women increasingly detach themselves from feminine representations produced by certain discourses of modernity. However, unequal relations, binary constructions of sex and gender, and exclusion whenever there is any sign of resistance are still signs of contemporaneity. In response to this situation, this research paper shows, through an archaeological and genealogical study, how love, as a feeling and emotion, was a subject of education for girls in the Colombian school during the first half of the twentieth century. In that sense, the author reflects upon emotions, feelings and discourses, and reveals how society shaped practices and legitimized truths that, even today, define both men’s and women’s nature.

  4. The Innovative Work of S. S. Glagolev: Theism in Russian Theological Academies of the Beginning of the Twentieth Century and Its Focusing on the Problem of Man

    Directory of Open Access Journals (Sweden)

    Marjana Ershova


    Full Text Available The author details the results of her study of the works of Sergey Sergeyevich Glagolev, a prominent professor of the Moscow Theological Academy. Glagolev’s heritage produces a profound impression by means of its versatility, its original way of looking at diverse problems as well as his unique solutions to the same problems. For this reason, it possesses enduring relevance. Despite this fact, his correspondence is still not well known nor understood. The author focuses on Glagolev’s analysis of the human problem. This choice may be explained by the fact that Sergey Sergeevich considered the problem of man to be the key issue behind the collision of religion and science taking place during the early twentieth century. Glagolev attempted to solve this problem by focusing on certain aspects of the subject: the origin of mankind, the interaction of the spirit and the body, the immortality of the soul, the origin of religion, as well as the way in which religious faith came about. A vital aspect of Glagolev’s treatment of the problem of man is his criticism of Charles Darwin and Darwinism, and thereby of the entire theory of evolution. Glagolev disagreed with the basic premises of this theory as well as with some of its specific conclusions. While opposing the concept of anthropo-genesis, Glagolev formulated his own theory regarding the origins of mankind. Thus, Glagolev viewed the origins and later history of mankind through the prism of his theory of degradation, which allowed him to seamlessly link the biblical narrative of the origins of man with contemporary scientific data. The author concludes that Glagolev was a major influence in the development of Russian theology during the first years of the twentieth century.

    Full Text Available This paper discusses how and why the Quakers dealt with human rights issues in the United States before 20th century, ranging from the mid 17th century to the mid 19th century. It applies Nash Smith’s interdisciplinary theory as a theoretical approach. The Quakers, as a Christian religious group, had got several features or identities since George Fox declared its existence in England in the mid of 17th century. They lived in simplicity, adopted the principle of pacifism, rejected paying tith and tax, rejected taking off hat, used archaic words, and so forth. However, the Quakers in the United States had shown a new feature or identity; namely, the enforcement of human rights in the eras before the 20th century. The human rights enforcement was motivated by their piety and loyality to the Quakerism. In other words, it was an expression of their belief in Quakerism. This theology empowered their thoughts and actions in responding issues pertaining to human rights of the minorities i.e. the Indians or Native Americans, the African-Americans, and women along the span of time. Their goal was to let the minorities enjoy their unalienable rights as what most of white men had enjoyed.

    The article discusses a set of pictures that illustrate public health activities, practices, and campaigns against malaria in Brazil from 1918 through 1956. Exemplary of certain key moments in this history, the illustrations belong to three archives from the Casa de Oswaldo Cruz/Fundação Oswaldo Cruz collection: Arquivo Belisário Penna, Arquivto Fundação Rockefeller ("Serviço de Malária do Nordeste" series), and Arquivo Rostan Soares. The article links these photographic records to their specific historical-public health contexts and to the campaign models and strategies represented by each archive. It also draws relations with the 20th -century history of the photographic medium itself. It is argued that these images of malaria constitute prime sources in constructing a visual history of the disease in 20th -century Brazil and of the country's public health history.

    Full Text Available This paper is devoted to the research of the history of participation Benenson and Golitsyn in the formation of financial and industrial group Russian-British bank in the Russian Empire. It is necessary to emphasize, that in the beginning of the 20 century joint-stock companies have occupied a prevailing situation in the main industrial and financial spheres of the Russian economy already. The densities of production, made by them, was dominant in many industries, making 70-80%, and sometimes more.

  13. [Emancipation of the works of artists with psychiatric illness - Artistic reflections from the twentieth century and the Art Brut]. (United States)

    Plesznivy, Edit


    The study presents the emancipation of the artworks of psychiatric patients through the review of four centuries, focusing on some of the most important medical cultural and art historical stages of the period between the 18th and the 21st century, which is a particularly relevant era in this regard. It touches on the collections linked to psychiatrists and hospitals that were formed primarily on the basis of the researches that were analyzing the connection between creativity and mental illness. After that, the study discusses the ever-changing attitudes and preferences of artists' and major artistic movements towards psychosis and the pictorial world of the psychotic. With great care, it analyses the aesthetic category of the art brut, which is connected to the French painter Jean Dubuffet and was born in the middle of the 1940s, and the relationship between contemporary art and art brut. In connection with some of the most significant art brut collections and exhibitions, the works of a few classical and contemporary art brut artists are also discussed (Adolf Wolfli, Louis Soutter, Aloise Corbaz, August Walla ).

  14. The reformist triad and institutional forgetting of culture: a field study into twentieth-century Swedish social medicine. (United States)

    Nyce, James M; Timpka, Toomas


    Social medicine deals with the interplay between medicine and society. An awareness of how analytical categories have emerged historically can strengthen the role the discipline can play in the societal reinventions of health care now under way around the world. This study examines the categories that informed social medicine in Sweden during the 20th century. An anthropological field study was conducted over a 12-year period in a Swedish academic clinical setting. Historical documents were used to link local-level issues with macro-level (here, national and European) contexts. Social medicine, modernity, and social democracy were found to share a common history and a common vision of what society should be. As a result, concepts from politics, ideology, economy, and science tended to be conflated. As a clinician at the study site explained, "samhälle [community] is both society and state". The consequence for social medicine is that culture has become neglected as an analytical category. This institutional amnesia has strongly influenced how 21st century social medicine, in this region of the world, has defined itself and its interests. To return a cultural perspective to social medicine, a critical distance must be kept between the analyses the discipline undertakes and the prevailing societal ideologies.

  15. Athens: New capital of traditional Greek music: Testimonies on musical life at the beginning of the twentieth century

    Directory of Open Access Journals (Sweden)

    Peno Vesna


    Full Text Available During its long Byzantine and Post-Byzantine history Constantinople was the center for church art in general, but especially for music. This old city on the Bosporus maintained its prime position until the beginning of the 20th century when, because of new political and social conditions, the Greek people started to acquire their independence and freedom, and Athens became the new capital in the cultural as well as the political sense. During the first decades of the 20th century the Athenian music scene was marked by an intensive dispute between those musicians who leaned towards the European musical heritage and its methods in musical pedagogy, and those who called themselves traditionalists and were engaged in the preservation of traditional values of church and folk music. The best insight into the circumstances in which Greek musical life was getting a new direction are offered by the numerous musical journals published in Athens before the First World War. Among them, The Formigs is of the special interest, firstly because of the long period during which it was published (1901-1912, and secondly because of its main orientation. The editor Ioannes Tsoklis, a church chanter, and his main collaborator, the famous Constantinopolitan musician and theorist and later Principal of the Department for Byzantine music at Athens musical school Konstantinos Psahos, with other associates firmly represented the traditional position. That is why most of the published articles and the orientation of the journal generally were dedicated to the controversial problems and current musical events that were attracting public attention. The editorial board believed that there was a connection between the preservation of musical traditions and their development on one side, and foreign musical influences that were evident in the promotion of polyphonic church music, which had been totally foreign to the Greek Orthodox church until the end of the 19th century, on

  16. Politics and pellagra: the epidemic of pellagra in the U.S. in the early twentieth century. (United States)

    Bollet, A. J.


    The epidemic of pellagra in the first half of this century at its peak produced at least 250,000 cases and caused 7,000 deaths a year for several decades in 15 southern states. It also filled hospital wards in other states, which had a similar incidence but refused to report their cases. Political influences interfered, not only with surveillance of the disease, but also in its study, recognition of its cause, and the institution of preventive measures when they became known. Politicians and the general public felt that it was more acceptable for pellagra to be infectious than for it to be a form of malnutrition, a result of poverty and thus an embarrassing social problem. Retrospectively, a change in the method of milling cornmeal, degermination, which began shortly after 1900, probably accounted for the appearance of the epidemic; such a process was suggested at the time, but the suggestion was ignored.

  17. Twentieth-century shifts in forest structure in California: Denser forests, smaller trees, and increased dominance of oaks. (United States)

    McIntyre, Patrick J; Thorne, James H; Dolanc, Christopher R; Flint, Alan L; Flint, Lorraine E; Kelly, Maggi; Ackerly, David D


    We document changes in forest structure between historical (1930s) and contemporary (2000s) surveys of California vegetation through comparisons of tree abundance and size across the state and within several ecoregions. Across California, tree density in forested regions increased by 30% between the two time periods, whereas forest biomass in the same regions declined, as indicated by a 19% reduction in basal area. These changes reflect a demographic shift in forest structure: larger trees (>61 cm diameter at breast height) have declined, whereas smaller trees (Forest composition in California in the last century has also shifted toward increased dominance by oaks relative to pines, a pattern consistent with warming and increased water stress, and also with paleohistoric shifts in vegetation in California over the last 150,000 y.

  19. Veterinary entomology, colonial science and the challenge of tick-borne diseases in South Africa during the late nineteenth and early twentieth centuries. (United States)

    Brown, K


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

    To analyse the institutionalisation of nutrition sciences in Spain in the second half of the twentieth century, and evaluate the activities of the journal Anales de Bromatología. Descriptive bibliometric study of the original articles. Full names of the authors and the complete article title were recorded. Using key words, each article was assigned by consensus of the researchers to a single main subject in accordance with the thirteen subject areas addressed by the Spanish Society of Bromatology in its meetings. An analysis was conducted of the distribution and trends of general productivity indicators and their characteristics. A total of 917 original articles were published, with a mean of 20.8 papers/year. The subjects for which the highest percentage of articles was recorded were foreign substances in foods, foods of plant origin and nutrition. A total of 874 authors contributed, with a collaboration rate of 2.43 and a transience rate of 70.1%. Distribution of the number of authors per article was close to that indicated by Lotka's law of scientific productivity. The top twelve producers, predominantly women, participated in 49.9% of the articles published. The journal showed low productivity and was of an endogamous nature, with a predominance of authors related to the School of Bromatology in the Faculty of Pharmacy, at the Complutense University. The subjects addressed reflected the demands of the nutrition transition in Spain.

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



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

  2. A Chronology of Annual-Mean Effective Radii of Stratospheric Aerosols from Volcanic Eruptions During the Twentieth Century as Derived From Ground-based Spectral Extinction Measurements (United States)

    Strothers, Richard B.; Hansen, James E. (Technical Monitor)


    Stratospheric extinction can be derived from ground-based spectral photometric observations of the Sun and other stars (as well as from satellite and aircraft measurements, available since 1979), and is found to increase after large volcanic eruptions. This increased extinction shows a characteristic wavelength dependence that gives information about the chemical composition and the effective (or area weighted mean) radius of the particles responsible for it. Known to be tiny aerosols constituted of sulfuric acid in a water solution, the stratospheric particles at midlatitudes exhibit a remarkable uniformity of their column-averaged effective radii r(sub eff) in the first few months after the eruption. Considering the seven largest eruptions of the twentieth century, r(sub eff) at this phase of peak aerosol abundance is approx. 0.3 micrometers in all cases. A year later, r(sub eff) either has remained about the same size (almost certainly in the case of the Katmai eruption of 1912) or has increased to approx. 0.5 micrometers (definitely so for the Pinatubo eruption of 1991). The reasons for this divergence in aerosol growth are unknown.

  3. "God save us from psychologists as expert witnesses": the battle for forensic psychology in early twentieth-century Germany. (United States)

    Wolffram, Heather


    This article is focused on the jurisdictional battle between psychiatrists and psychologists over psychological expertise in legal contexts that took place during the first decades of the 20th century. Using, as an example, the debate between the psychologist William Stern, the psychiatrist Albert Moll, and the jurist Albert Hellwig, which occurred at the International Congress for Sexual Research held in Berlin in 1926, it aims to demonstrate the manner in which psychiatrists' responses to psychologists' attempts to gain admittance to Germany's courtrooms were shaped not only by epistemological and methodological objections, but also by changes to expert witnessing that had already encroached on psychiatrists' professional territory. Building upon recent work examining the relationship between psychologists and jurists prior to the First World War, this article also seeks to examine the role of judges and lawyers in the contest over forensic psychology in the mid-1920s, arguing that they ultimately became referees in the increasingly public disputes between psychiatrists and psychologists.

  6. Judging Edward Teller: A Closer Look at One of the Most Influential Scientists of the Twentieth Century

    Energy Technology Data Exchange (ETDEWEB)

    Libby, S B


    Much has been written about Edward TEller, but little of it is objective. Given, on the one hand, his position as one of the most inventive theoretical physicists of the 20th century, and on the other, his central role in the development and advocacy of thermonuclear weapons, one might imagine it impossible at this point in history to write a scholarly, impartial account of Teller's life and his impact. Now, however, Istvan Hargittai, a prominent Hungarian physical chemist and historian of science, has written a balanced, thoughtful, and beautifully research biography that comes closest. Hargittai is uniquely qualified for this difficult task. Coming a generation and a half later from a similar Hungarian-Jewish background, Hargittai understands well the influences and terrible events that shaped Teller. The advent of virulent, political anti-Semitism, first in Hungary and then in Germany, made Teller twice a refugee. Both Teller and Hargittai lost close family in the Holocaust; Hargittai was himself liberated from a Nazi concentration camp as a child. While Teller was in the US by then, his and Hargittai's surviving family members in Hungary suffered mistreatment at the hands of the postwar Hungarian Communist dictatorship. Hargittai's informed Eastern European perspective also provides a fresh viewpoint to the cold war context of the second half of Teller's career. Furthermore, Hargittai's own scientific work in molecular structure clearly makes him appreciate of Teller's breakthroughs in that field in the 1930s.

The study is based on the articles from Jewish weeklies, magazines and newspapers from pre-war Bosnia and Hercegovina and from Germany/Poland. It demonstrates a double-sided attitude towards the languages. On the one hand – an image of the languages as determinants of Jewish identity. Touching on this theme, the authors of the paper also try to highlight the images of Yiddish and Judeo-Spanish and as determinants in a narrower sense – of the Sephardi/Ashkenazi identity in that period. On the other hand, the paper shows a tendency to treat the languages as “corrupted” and “dying” languages, and as factors slowing down the assimilation of Jewish groups and also as an obstacle for Zionist ideologies.   Języki jidysz i żydowsko-hiszpański jako wskaźniki tożsamości – na przykładzie żydowskich tekstów prasowych pierwszej połowy XX wieku Artykuł ukazuje obraz i funkcje języków jidysz i żydowsko-hiszpańskiego wśród żydowskich grup diasporowych – bałkańskich Sefardyjczyków oraz Aszkenazyjczyków (Ostjuden – w okresie od początków wieku XX do wybuchu II wojny światowej.

  11. Avalanche related damage potential - changes of persons and mobile values since the mid-twentieth century, case study Galtür (United States)

    Keiler, M.; Zischg, A.; Fuchs, S.; Hama, M.; Stötter, J.


    When determining risk related to natural hazard processes, many studies neglect the investigations of the damage potential or are limited to the assessment of immobile values like buildings. However, persons as well as mobile values form an essential part of the damage potential. Knowledge of the maximum number of exposed persons in an endangered area is of great importance for elaborating evacuation plans and immediate measures in case of catastrophes. In addition, motor vehicles can also be highly damaged, as was shown by the analysis of avalanche events. With the removal of mobile values in time as a preventive measure this kind of damage can be minimised. This study presents a method for recording the maximum number of exposed persons and monetarily assessing motor vehicles in the municipality of Galtür (Tyrol, Austria). Moreover, general developments of the damage potential due to significant socio-economic changes since the mid-twentieth century are pointed out in the study area. The present situation of the maximum number of persons and mobile values in the official avalanche hazard zones of the municipality is described in detail. Information on the number of persons is derived of census data, tourism and employment statistics. During the winter months, a significant increase overlaid by strong short-term fluctuation in the number of persons can be noted. These changes result from a higher demand of tourism related manpower as well as from varying occupancy rates. The number of motor vehicles in endangered areas is closely associated to the number of exposed persons. The potential number of motor vehicles is investigated by means of mapping, statistics on the stock of motor vehicles and the density distribution. Diurnal and seasonal fluctuations of the investigated damage potential are pointed out. The recording of the number of persons and mobile values in endangered areas is vital for any disaster management.

  13. The Debate about the Origin of Venereal Disease and VD Control in Modern China : Focusing on Shanghai and Beijing in the First Half of the Twentieth Century

    Full Text Available This paper examines venereal disease(VD control in Shanghai and Beijing in the first half of the twentieth century. It focuses on the debate about the origin of VD in which western doctors stressed the importance of prostitution rather than VD itself. While missionary western doctors approached VD and prostitution from a moral perspective, Chinese western doctors adopted a public health approach. Because Chinese western doctors favored the medium of popular magazines and newspapers to publicize VD and enlighten the public, it is difficult to find their writings on VD in the medical journals such as The National Medical Journal of China(NMJ. Therefore, Chinese western doctors had not been indifferent to VD as previously thought. Common people preferred the black market to the open clinic, and abused salvarsan to cure VD in secret. This suggests the sensitive nature of VD as a disease that degrades personal honor. VD control varied depending on the perspective of the origin of VD and the prostitution, and measures taken. While moralists in the debate upheld a position to abolish licensed prostitution, public health enthusiasts propped up licensed prostitution. VD control in Shanghai and Beijing displays a striking contrast. In Shanghai, the power to control VD and prostitutes were separated. The Shanghai Municipal Council(SMC, French Municipal Council(FMC, and Shanghai Municipality(SM did not cooperate in the control of VD and prostitutes. When SMC devoted its energies to abolish licensed prostitution, FMC and SM enjoyed prostitute's taxes. The Beiping Municipality(1928-1937 practiced multiple forms of control patterns and targets of VD. They adopted a bifurcated policy regarding VD. The targets of diagnosis were divided into prostitute, pregnant women, and normal citizen. The range of the reach of the health administration in Beiping Municipality was gradually magnified.

  15. Reassessment of 20th century global mean sea level rise (United States)

    Dangendorf, Sönke; Marcos, Marta; Wöppelmann, Guy; Conrad, Clinton P.; Frederikse, Thomas; Riva, Riccardo


    The rate at which global mean sea level (GMSL) rose during the 20th century is uncertain, with little consensus between various reconstructions that indicate rates of rise ranging from 1.3 to 2 mm⋅y−1. Here we present a 20th-century GMSL reconstruction computed using an area-weighting technique for averaging tide gauge records that both incorporates up-to-date observations of vertical land motion (VLM) and corrections for local geoid changes resulting from ice melting and terrestrial freshwater storage and allows for the identification of possible differences compared with earlier attempts. Our reconstructed GMSL trend of 1.1 ± 0.3 mm⋅y−1 (1σ) before 1990 falls below previous estimates, whereas our estimate of 3.1 ± 1.4 mm⋅y−1 from 1993 to 2012 is consistent with independent estimates from satellite altimetry, leading to overall acceleration larger than previously suggested. This feature is geographically dominated by the Indian Ocean–Southern Pacific region, marking a transition from lower-than-average rates before 1990 toward unprecedented high rates in recent decades. We demonstrate that VLM corrections, area weighting, and our use of a common reference datum for tide gauges may explain the lower rates compared with earlier GMSL estimates in approximately equal proportion. The trends and multidecadal variability of our GMSL curve also compare well to the sum of individual contributions obtained from historical outputs of the Coupled Model Intercomparison Project Phase 5. This, in turn, increases our confidence in process-based projections presented in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. PMID:28533403

  16. Two centuries of extreme events over the Baltic Sea and North Sea regions (United States)

    Two centuries of extreme events over the Baltic Sea and North Sea regions In the framework of the BACC 2 (for the Baltic Sea) and NOSCCA projects (for the North Sea region), studies of past and present variability and changes in atmospheric variables within the North Sea region over the instrumental period (roughly the past 200 years) have been investigated. Findings on trends in temperature and precipitation have already been presented. Here we focus on data homogeneity issues and examine how reliable reanalyses are in this context. Unlike most other regions in the world, there is a wealth of old observations available for the Baltic and North Sea regions, most of it in handwritten form in meteorological journals and other publications. These datasets need to be carefully digitised and homogenized. For this, a thorough quality control must be applied; otherwise the digitised datasets may prove useless or even counterproductive. We present evidence that this step cannot be conducted without human interference and thus cannot be fully automated. Furthermore, inhomogeneities due to e.g. instrumentation and station relocations need to be addressed. A wealth of reanalysis products is available, which can help detect such inhomogeneities in observed time series, but at the same time are prone to biases and/or spurious trends themselves e.g. introduced by changes in the availability and quality of the underlying assimilated data. It therefore in general remains unclear in how far we can simulate the pre-satellite era with respect to homogeneity with reanalyses based only on parts of the observing system. Extreme events and changes in extreme situations are more important and of greater (societal) significance than changes in mean climate. However, changes in extreme weather events are difficult to assess not only because they are, per definition, rare events, but also due to the homogeneity issues outlined above. Taking these into account, we present evidence for changes

  19. Changes in the Authority of the Father in the Polish Family in the Twentieth Century. The Interpretation from the Historical and Pedagogical Perspective [Przemiany autorytetu ojca w rodzinie polskiej w XX wieku. Interpretacja z perspektywy historyczno-pedagogicznej

    Directory of Open Access Journals (Sweden)

    Paweł ŚPICA


    Full Text Available Nowadays numerous researchers are interested in the subject area concerning fatherhood, including the father’s role in bringing up the child. It is not coincidental. In the last couple of years the position of men has significantly changed in Polish families. Jerzy Witczak has indicated that since the 1970s the role of man has not been thoroughly defined. The changes have led to the modification the roles of fathers, previously which were traditionally based on taking care of material needs and representing the family to the outside world. While in the first half of the twentieth century the role of man in family was clearly defined, in the second half of the twentieth century the father’s authority was increasingly contested. The reasons for this state of affairs lie in the transformations that took place in Polish culture and in socio-economic policy. Consequently traditional educational methods upon which parents used to build their authority ceased to be effective in the educational practise. Increasingly, researchers have begun to ask questions concerning the importance of father in the process of raising a child. However, the transformation of family life in the twentieth-century Poland did not proceed equally in all social classes. Fathers from the villages held different positions than men living in the cities. The latter group adopted the so-called urban lifestyle. There is no doubt, however, that in the first and second environment – although in varying degrees – the father as the head of the family has lost its dominant position. In order to understand why the old methods stopped working, we should look through the prism of social history and we should not forget about the consequences of political and economical transformations, which directly and indirectly influenced the transformations of Polish families in the twentieth century. The main aim of the article is to provide the historical context and the scholars

  20. XXI century projections of wind-wave conditions and sea-level rise in the Black sea (United States)

    Polonsky, A.; Garmashov, A.; Fomin, V.; Valchev, N.; Trifonova, E.


    Projection of regional climate changes for XXI century is one of the priorities of EC environmental programme. Potential worsening of the waves' statistics, sea level rise and extreme surges are the principal negative consequences of the climate change for marine environment. That is why the main purpose of this presentation is to discuss the above issue for the Black sea region (with a strong focus to the south-west subregion because the maximum heights of waves exceeding 10 m occur just here) using output of several global coupled models (GCM) for XXI century, wave simulation, long-term observations of sea level and statistical techniques. First of all we tried to choose the best coupled model (s) simulated the Black sea climate change and variability using the control experiments for 20 century (203). The principal result is as follows. There is not one model which is simulating adequately even one atmospheric parameter for all seasons. Therefore we considered (for the climate projection) different outputs form various models. When it was possible we calculated also the ensemble mean projection for the selected model (s) and emission scenarios. To calculate the wave projection we used the output of SWAN model forced by the GCM wind projection for 2010 to 2100. To estimate the sea level rise in XXI century and future surges statistics we extrapolate the observed sea level rise tendencies, statistical relation between wave heights and sea level and wave scenarios. Results show that in general, the climate change in XXI century doesn't lead to the catastrophic change of the Black sea wind-wave statistics including the extreme waves in the S-W Black sea. The typical atmospheric pattern leading to the intense storm in the S-W Black sea is characterized by the persistent anticyclonic area to the North of the Black sea and cyclonic conditions in the Southern Black sea region. Such pressure pattern causes persistent and strong eastern or north-eastern wind which

  1. Observation-Driven Estimation of the Spatial Variability of 20th Century Sea Level Rise (United States)

    Hamlington, B. D.; Burgos, A.; Thompson, P. R.; Landerer, F. W.; Piecuch, C. G.; Adhikari, S.; Caron, L.; Reager, J. T.; Ivins, E. R.


    Over the past two decades, sea level measurements made by satellites have given clear indications of both global and regional sea level rise. Numerous studies have sought to leverage the modern satellite record and available historic sea level data provided by tide gauges to estimate past sea level rise, leading to several estimates for the 20th century trend in global mean sea level in the range between 1 and 2 mm/yr. On regional scales, few attempts have been made to estimate trends over the same time period. This is due largely to the inhomogeneity and quality of the tide gauge network through the 20th century, which render commonly used reconstruction techniques inadequate. Here, a new approach is adopted, integrating data from a select set of tide gauges with prior estimates of spatial structure based on historical sea level forcing information from the major contributing processes over the past century. The resulting map of 20th century regional sea level rise is optimized to agree with the tide gauge-measured trends, and provides an indication of the likely contributions of different sources to regional patterns. Of equal importance, this study demonstrates the sensitivities of this regional trend map to current knowledge and uncertainty of the contributing processes.

  2. “Gate and Port of the South of Argentina”? Nuances and Debates in the Image of Bahia Blanca City in Its Regional Context in the Mid-twentieth Century

    Directory of Open Access Journals (Sweden)

    Juliana López Pascual


    Full Text Available For over a century the people of Bahia Blanca, Argentinian port city located at the south west of the province of Buenos Aires, they have imagined it and defined it not only as part of the Patagonian territories but also as their legitimate political, economic and cultural center. The aim of historicizing and questioning this idea, trying to account for the interests that were mobilized, the ideological postures that hinted, and the impact it had on the effective regional layout, is what motivates our research. To that end, this article does focus on economic and infrastructural dimension that some debates of mid-twentieth century used simultaneously as evidence and as ultimate goal of this alleged hegemony. For this purpose, we will analyze the writings of Domingo Pronsato and Ricardo M. Ortiz whom, from different geopolitical perspectives, devised specific roles for the city that suited their plans for the regional development of Patagonia.

    In this study, we use IP25 and alkenone biomarker proxies to document the subdecadal variations of sea ice and sea surface temperature in the subpolar North Atlantic induced by the decadally paced explosive tropical volcanic eruptions of the second half of the thirteenth century. The short-and long......-term evolutions of both variables were investigated by cross analysis with a simulation of the IPSL-CM5A LR model. Our results show short-term ocean cooling and sea ice expansion in response to each volcanic eruption. They also highlight that the long response time of the ocean leads to cumulative surface cooling...... and subsurface heat buildup due to sea ice capping. As volcanic forcing relaxes, the surface ocean rapidly warms, likely amplified by subsurface heat, and remains almost ice free for several decades....

  5. Time and Time Again; Determination of longitude at sea in the 17th Century (United States)

    de Grijs, Richard


    Determination of one's longitude at sea has perplexed sailors for many centuries. The significant uptake of world trade in the 17th and 18th Centuries rendered the increasingly urgent need to solve the 'longitude problem', an issue of strategic national importance. Historical accounts of these efforts often focus almost exclusively on John Harrison's role in 18th-Century Britain. This book starts instead from Galileo Galilei's late-16th-Century development of an accurate pendulum clock, which was first achieved in practice in the mid-17th-Century by Christiaan Huygens in the Dutch Republic. It is primarily based on collections of letters that have not been combined into a single volume before. Extensive introductory chapters on the history of map making, the establishment of the world's reference meridian at Greenwich Observatory, and the rise of the scientific enterprise provide the appropriate context for non-expert readers to fully engage with the book's main subject matter.

  7. Dwudziestowieczna filozofia analityczna. O pewnej próbie całościowego ujęcia (TWENTIETH-CENTURY ANALYTIC PHILOSOPHY. ON A RECENT ATTEMPT OF ITS GENERAL ACCOUNT

    Directory of Open Access Journals (Sweden)

    Tadeusz Szubka


    Full Text Available Although analytic philosophy is a major movement shaping contemporary philosophy, there are not too many historical accounts of that movement which would be comprehensive, unified and sufficiently detailed. An impressive attempt to fill in this lacuna is the two-volume book 'Philosophical Analysis in the Twentieth Century', modestly described by its author Scott Soames (renowned mainly for his work in the philosophy of language as 'an introductory overview of the analytic tradition in philosophy covering roughly the period between 1900 and 1975'. The first volume discusses the philosophy of G.E. Moore, the most influential views of Bertrand Russell, Ludwig Wittgenstein's 'Tractatus', logical positivism (including emotivism in ethics and reaction against it, as well as the early philosophy of W.V. Quine. The second volume continues the story of analytic philosophy by providing an account of the later philosophy of Wittgenstein, the ordinary language philosophy and its demise, the philosophical naturalism of W.V. Quine, the theory of meaning of Donald Davidson, and finally Saul Kripke's seminal philosophy of language and its wide-ranging implications. The book contains also a short epilogue outlining the direction taken by analytic philosophy in the last quarter of the twentieth century. The two volumes of Soames' account of contemporary analytic tradition are packed with lucid, sophisticated and detailed discussions of various views of major thinkers of that tradition. However, besides these merits the book by Soames has several weaker points. It defines analytic philosophy in a rather loose and unspecific manner, as well as gives an arbitrarily selective and unbalanced account of its recent developments.

  8. The land-ice contribution to 21st-century dynamic sea level rise (United States)

    Howard, T.; Ridley, J.; Pardaens, A. K.; Hurkmans, R. T. W. L.; Payne, A. J.; Giesen, R. H.; Lowe, J. A.; Bamber, J. L.; Edwards, T. L.; Oerlemans, J.


    Climate change has the potential to influence global mean sea level through a number of processes including (but not limited to) thermal expansion of the oceans and enhanced land ice melt. In addition to their contribution to global mean sea level change, these two processes (among others) lead to local departures from the global mean sea level change, through a number of mechanisms including the effect on spatial variations in the change of water density and transport, usually termed dynamic sea level changes. In this study, we focus on the component of dynamic sea level change that might be given by additional freshwater inflow to the ocean under scenarios of 21st-century land-based ice melt. We present regional patterns of dynamic sea level change given by a global-coupled atmosphere-ocean climate model forced by spatially and temporally varying projected ice-melt fluxes from three sources: the Antarctic ice sheet, the Greenland Ice Sheet and small glaciers and ice caps. The largest ice melt flux we consider is equivalent to almost 0.7 m of global mean sea level rise over the 21st century. The temporal evolution of the dynamic sea level changes, in the presence of considerable variations in the ice melt flux, is also analysed. We find that the dynamic sea level change associated with the ice melt is small, with the largest changes occurring in the North Atlantic amounting to 3 cm above the global mean rise. Furthermore, the dynamic sea level change associated with the ice melt is similar regardless of whether the simulated ice fluxes are applied to a simulation with fixed CO2 or under a business-as-usual greenhouse gas warming scenario of increasing CO2.

The situation within the Czech family illustrates the current problems in family ties and intergenerational relationships that have surfaced since the nineteen nineties. Negative developmental trends are being seen, particularly in comparison with family circumstances in other European countries, most significantly the continuing ageing of the population and the wide-ranging activities of seniors. Looser relationships with their families and a decline in their engagement in caring for their grandchildren mean that Czech grandparents tend to rank alongside more socially developed countries in this respect. Under Czech conditions, however, this can lead to great strain on the active roles played by seniors. The growing number of adult offspring, particularly men, living with their parents is a far from progressive trend in social and economic development, and corresponds more closely with southern European traditions. A preference for alternative forms of cohabitation, particularly among partners with primary education, the postponing of the birth of the first child, the growth in the number of single-person households and, perhaps most importantly, the enormous rise in the number of households comprised of young or middle-aged individuals in the economically productive age group may, it is true, rank the Czech Republic among socially developed countries and at around the European average, though in view of the unfavourable demographic trend a fundamental change in state support for marriage and the family is, however, also essential in the Czech Republic. The fact is that more than a third of families with children are threatened with poverty. The conclusion arising from the analyses performed indicates that the current problems in state social and family policy are reflected in the increasing

    Full Text Available The author examines the relationship between scientific and theological components in a selection of the works of well-known Biblical scholars active at the Kiev Theological Academy around the turn of the nineteenth century and the begin ning of the twentieth. Among them figure the names of F. J. Pokrovsky, V. P. Rybinsky, D. I. Bogdashevsky, and Father A. A. Glagolev. The work of these experts has been little studied until today. The spiritual, intellectual, and ideological context of the time has been taken into account by the author. The author of this article pays special attention to the ideological background surrounding the polemic between Russian Orthodox biblical scholars and those proponents of the negative school of biblical exegesis. The focus is on several key elements of understanding the Bible, the research and exposition of biblical history, as well as points of dogmatic and moral import stemming from an interpretation of the scriptures. The author demonstrates that the position of the Kievan biblical scholars was apologetic, contrasting the theological and scientific schools against the background of a more than positivistic understanding of history and the Bible seen as the sacred scripture of the Church. In this way, they contributed to academic research, and the way of teaching the scriptures of the schools, as well as the exposition of the scriptures for the purpose of dogmatic and moral enlightenment. At the same time, they began the process of working towards a synthesis as an approach for further scientific and theological research. Important for the continuing development of Russian Orthodox biblical studies during the twentieth century was finding a balance between Orthodox biblical apologetics and scientific thought . This attempt at re-discovering and reconstructing the apologetic atmosphere of the Kievan biblical scholars was made possible through a combination of several factors — one of the most important being

  13. A European Culture War in the Twentieth Century? Antic-Catholicism and Anti-Bolshevism between Moscow, Berlin, and the Vatican 1922 to 1933


    Weir, Todd


    The term “culture war” has become a generic expression for secular-catholic conflicts across nineteenth-century Europe. Yet, if measured by acts of violence, anticlericalism peaked in the years between 1927 and 1939, when thousands of Catholic priests and believers were imprisoned or executed and hundreds of churches razed in Mexico, Spain and Russia. This essay argues that not only in these three countries, but indeed across Europe a culture war raged in the interwar period. It takes, as a c...

  14. Women in Chemistry: Their Changing Roles from Alchemical Times to the Mid-Twentieth Century (by Marelene Rayner-Canham and Geoffrey Rayner-Canham) (United States)

    Caserio, Marjorie C.


    Women who made significant contributions in the chemical sciences prior to the 20th century do not come readily to mind. Yet, as this book relates so engagingly, women have been influential in chemistry since the earliest period of recorded history. However, Women in Chemistry is more than a dated collection of biographical sketches of notable women scientists. The book highlights the main periods of history when it was possible for women to have some measure of success in the chemical sciences and focuses on their changing roles from alchemical times to the mid-20th century. By glimpsing into the life and work of individuals in the context of the time in which they lived, the authors impart a credible and moving image of the restraints imposed on aspiring women scientists and the obstacles that confronted them-making the extent of their contributions all the more remarkable. Each chapter has a theme into which are woven selected biographical sketches. Chapter 1 offers a whirlwind tour of the centuries from Babylonian times (1200 B.C.E.) through the Middle Ages and into the 17th century, giving perspective on how the various civilizations did (or did not) consider women capable of intellectual achievement or permit such of them. This short but powerful chapter invokes appreciation for the major contributions made by women in the face of enormous obstacles of prejudice, superstition (witchcraft), monastic reprisals, pseudoscience (alchemy), and denial of education. The women featured include Maria Hebraea (around 300 C.E.famed for the water bath, bain Marie), Hypatia (mathematician, 400 C.E.), Western alchemists (de Gourney and Meudrac), and Chinese alchemists. By the 18th century, science had progressed and alchemy was at an end. Though enlightened scientifically, western society still considered women's intellect inferior. But, as Chapter 2 relates, the literary salons of France nurtured intellectual discussion in society women, and it was in this context that

  15. Léon Marillier and the veridical hallucination in late-nineteenth- and early-twentieth-century French psychology and psychopathology. (United States)

    Le Maléfan, Pascal; Sommer, Andreas


    Recent research on the professionalization of psychology at the end of the nineteenth century shows how objects of knowledge which appear illegitimate to us today shaped the institutionalization of disciplines. The veridical or telepathic hallucination was one of these objects, constituting a field both of division and exchange between nascent psychology and disciplines known as 'psychic sciences' in France, and 'psychical research' in the Anglo-American context. In France, Leon Marillier (1862-1901) was the main protagonist in discussions concerning the concept of the veridical hallucination, which gave rise to criticisms by mental specialists and psychopathologists. After all, not only were these hallucinations supposed to occur in healthy subjects, but they also failed to correspond to the Esquirolian definition of hallucinations through being corroborated by their representation of external, objective events. © The Author(s) 2015.

  16. Innovation in hydroelectric power plant design in early twentieth century. Casto Fernández-Shaw's Engineering Architecture in La Jándula dam

    A. B. Berrocal Menárguez


    Full Text Available The power plant location in the first hydroelectrial dams was a relevant issue at the end of XIX century and early XX. Different solutions were tried, some of them with very interesting aesthetics results and hydraulic and structural implications. Such is the case of La Jándula dam, inaugurated in 1930, that includes the power station inside the dam. This article examines the possible national and international inspirations of this singular solution, corroborating the hypothesis of its unprecedented nature. The collaboration of the architect Casto Fernández-Shaw in the design and integration of the engine room was decisive, because it achieved a result of an aesthetic quality and formal expressiveness unprecedented in a work of hydraulic engineering, as well as the birth of a style Shaw himself defined as architectural engineering.

    Judit Kádár


    Full Text Available In this paper, I examine some literary texts of two turn-of-the century Hungarian women writers, Anna Tutsek and Terka Lux who left behind their childhood environment in remote regions of the Austro-Hungarian Monarchy in order to move to Budapest, the capital of the eastern part of the Empire. Assuming that individuals hold multiple identities that are flexible and inevitably affected by environmental and social changes, my main focus is on the transformation of their ethnic, regional, occupational and gender identity influenced by the disengagement from their birthplace. Within a context of Hungarian−Eastern-European women's social history, I investigate how migration had led them to reshape their original identities and create new ones and how these emigrant writers reacted to the loss of cultural and social norms in which they had previously lived.

    Directory of Open Access Journals (Sweden)

    Arnold Witte


    Full Text Available German Art History and Scientific Thought – Beyond Formalism discusses the relation between art history and the human and natural sciences in the late nineteenth and early twentieth centuries. All contributions in this volume highlight the way in which this exchange affected art history on a practical and methodological level, but at the same time illustrate how the quest for objectivity and scientific methods was accompanied by an irrational search for essential characteristics of art through race. Especially the exchange with psychology, physiognomy, and psychophysiology supported this kind reasoning in circles in which objectivity was related to holistic explanations. This led to a rhetoric of objective Kunstwissenschaft that spoke in terms of rational facts, but in which the concepts of character and evolution resulted in highly ideological interpretations, which became discredited after 1945. However, the post-war reaction to this in itself again affected another turn towards the ‘objective’ which goes to show how external, political, changes affected the relation between art history and the sciences.

    Full Text Available O objetivo do artigo é esclarecer de que modo a paulatina legitimação dos padrões de relacionamento romântico ocorrida no século passado - conforme pregados por várias defensoras da reforma dos costumes e promovidos por meios de comunicação em massa - enfrenta a resistência, entre os setores partidários do racionalismo terapêutico, de um discurso em favor do intimismo amoroso. A hipótese é de que o sentido dessa reação seja o de proteção contra os efeitos negativos potencialmente gerados pela crença em certo tipo de romantismo e suas promessas de felicidade, em meio à ordem social individualista e desprovida de salvaguardas tradicionais.The article seeks to explain how the gradual legitimation of romantic relationships over the course of the last century - advocated by socials reformers and propagated by the mass media - have met with resistance from a discourse in favour of amorous intimacy among followers of therapeutic rationalism. The text argues that this reaction comprises a defensive protection against the negative effects potentially generated by the belief in a certain type of romanticism and its promises of happiness within a individualistic social order lacking in the traditional safeguards.

  20. The rise of a science in the early twentieth century: the forgotten voice of Gualtiero Sarfatti and the first "social psychology" volumes in Italy. (United States)

    Sensales, Gilda; Dal Secco, Alessandra


    Establishing social psychology as a distinct field of study has been the object of heated debate over the first decades of the 20th century. Entrenched in different theoretical traditions, such as philosophy, sociology, psychology, and criminology, the development of the conceptual boundaries of social psychology as an autonomous science was the result of a historic effort. Resulting from a negotiation process between competing stances, some voices relevant to the identity construction of social psychology have been lost over time. Within the framework of a "polycentric" historical perspective valorizing local histories, the present study aims to scrutinize those early voices, which were later marginalized. To this scope, we conducted a narrative analysis on the first volumes explicitly naming social psychology in their titles and identified the main themes, conceptual frameworks, and scientific advancements. The analysis illustrates the work of Gualtiero Sarfatti and articulates his forgotten contribution to drawing social psychology as a distinct discipline, built on the scientific method and positioned within the psychological sociocentric tradition. Our analysis reveals the leading role of Sarfatti in the disciplinary foundation of social psychology as a psychological science based on the concept of social psyche. Yet despite the fact his contribution was influential in the scholarly community of his time, our work highlights how his voice vanished from the subsequent disciplinary developments to date, and suggests some explanations behind this neglect.

  1. Two centuries of observed atmospheric variability and change over the North Sea region (United States)

    Stendel, Martin; van den Besselaar, Else; Hannachi, Abdel; Kent, Elizabeth; Lefebvre, Christiana; Rosenhagen, Gudrun; Schenk, Frederik; van der Schrier, Gerard; Woollings, Tim


    In the upcoming North Sea Region Climate Change Assessment (NOSCCA), we present a synthesis of current knowledge about past, present and possible future climate change in the North Sea region. A climate change assessment from published scientific work has been conducted as a kind of regional IPCC report, and a book has been produced that will be published by Springer in 2016. In the framework of the NOSCCA project, we examine past and present studies of variability and changes in atmospheric variables within the North Sea region over the instrumental period, roughly the past 200 years, based on observations and reanalyses. The variables addressed in this presentation are large-scale circulation, pressure and wind, surface air temperature, precipitation and radiative properties (clouds, solar radiation, and sunshine duration). While air temperature over land, not unexpectedly, has increased everywhere in the North Sea region, with strongest trends in spring and in the north of the region, a precipitation increase has been observed in the north and a decrease in the south of the region. This pattern goes along with a north-eastward shift of storm tracks and is in agreement with climate model projections under enhanced greenhouse gas concentrations. For other variables, it is not obvious which part of the observed changes may be due to anthropogenic activities and which is internally forced. It remains also unclear to what extent atmospheric circulation over the North Sea region is influenced by distant factors, in particular Arctic sea-ice decline in recent decades. There are indications of an increase in the number of deep cyclones (but not in the total number of cyclones), while storminess since the late 19th century shows no robust trends. The persistence of circulation types appears to have increased over the last century, and consequently, there is an indication for 'more extreme' extreme events. However, changes in extreme weather events are difficult to assess

  3. Sea Level Rise in the 21st Century: Will projections ever become reliable? (United States)

    Willis, J. K.


    Global sea level rise has the potential to become one of the most costly and least well predicted impacts of human caused climate change. Unlike global surface temperature, the spread of possible scenarios (as little as 1 foot and as much as 6 feet by 2100) is not due to uncertainty about future rates of greenhouse gas emissions, but rather by a fundamental lack of knowledge about how the major ice sheets will behave in a warming climate. Clearly improved projections of sea level rise should become a major research priority in the next decade. At present, controversial techniques based on comparison with historical analogs and rates of recent warming and sea level rise are often used to create projections for the 21st Century. However, many in the scientific community feel that reliable projections must be based on a sound knowledge of the physics governing sea level rise, and particularly ice sheet behavior. In particular, large portions of the West Antarctic Ice Sheet and parts of the Greenland Ice Sheet rest on solid earth that sits below sea level. These regions may be threatened, not by atmospheric warming or changes in precipitation, but rather by direct forcing from the ocean. Fledgling efforts to understand these ocean ice interactions are already underway, as are efforts to make improved models of ice sheet behavior. However a great deal of work is still needed before widely accepted projections of sea level rise become a reality. This paper will highlight the hurdles to making such projections today and suggest ways forward in this critical area of research.

  4. Uncertainty in Twenty-First-Century CMIP5 Sea Level Projections (United States)

    Little, Christopher M.; Horton, Radley M.; Kopp, Robert E.; Oppenheimer, Michael; Yip, Stan


    The representative concentration pathway (RCP) simulations included in phase 5 of the Coupled Model Intercomparison Project (CMIP5) quantify the response of the climate system to different natural and anthropogenic forcing scenarios. These simulations differ because of 1) forcing, 2) the representation of the climate system in atmosphere-ocean general circulation models (AOGCMs), and 3) the presence of unforced (internal) variability. Global and local sea level rise projections derived from these simulations, and the emergence of distinct responses to the four RCPs depend on the relative magnitude of these sources of uncertainty at different lead times. Here, the uncertainty in CMIP5 projections of sea level is partitioned at global and local scales, using a 164-member ensemble of twenty-first-century simulations. Local projections at New York City (NYSL) are highlighted. The partition between model uncertainty, scenario uncertainty, and internal variability in global mean sea level (GMSL) is qualitatively consistent with that of surface air temperature, with model uncertainty dominant for most of the twenty-first century. Locally, model uncertainty is dominant through 2100, with maxima in the North Atlantic and the Arctic Ocean. The model spread is driven largely by 4 of the 16 AOGCMs in the ensemble; these models exhibit outlying behavior in all RCPs and in both GMSL and NYSL. The magnitude of internal variability varies widely by location and across models, leading to differences of several decades in the local emergence of RCPs. The AOGCM spread, and its sensitivity to model exclusion and/or weighting, has important implications for sea level assessments, especially if a local risk management approach is utilized.

  5. Women’s Activism and Innovation in Education: the Role of the Unione Femminile Nazionale in Sicily for the Transformation of Italian Pedagogy at the Beginning of the Twentieth Century

    Directory of Open Access Journals (Sweden)

    Letterio Todaro


    Full Text Available The beginning of the twentieth century represented a special occasion in the development of women’s movements as a vehicle for a new culture of education. The growing role of women’s associations in modern society found fertile ground in the increasing demand for childcare. In Italy such a process reflected a meaningful phenomenon of social transformation, which was linked to the ascent of the lower classes and to the progression of democratic values. In a region like Sicily, the appearance of local branches of the Unione Femminile Nazionale in some principal cities of the isle, such as Catania, from 1909 onwards represented a crucial opportunity not only for the social and cultural elevation of working-class children, but also for the introduction of new models of schooling and the experimentation of new methods in education, within the wider framework of a general renewal in the science of education of the time. The most representative witness and «learner» of these innovative approaches to education was Giuseppe Lombardo Radice, who was to «transfer» many aspects of his experience into the reform of the entire primary school system in Italy (1923 in line with the design of «active schooling». A survey of the experience of the Sicilian sections of the Unione provides not only a significant example of civilization processes promoted by women’s activism, but also a key to better understanding the wealth of resources involved in the construction of a modern pedagogy in Italy before the coming of Fascism.

    Full Text Available Cartagena de Indias, puerto en el Caribe colombiano, convivió durante su historia con la desventaja de no poder ofrecer condiciones de salubridad a sus habitantes y visitantes. La falta de un acueducto y de un sistema de alcantarillado fueron obstáculos para el progreso de la ciudad. Estos problemas provocaron, casi por cuarenta años (1890-1930, un sinnúmero de discursos de medicalización formulados por científicos, técnicos y políticos. El aporte de Cartagena a la solución del problema de la higiene de las ciudades consistió en aprovechar el saber del ingeniero. La construcción del equipamiento urbano, a comienzos del siglo XX, requirió la presencia de un conocimiento más técnico que planteara una solución integral para el problema del agua, garantizando abastecimiento suficiente y eficiente evacuación. Así, en el último cambio de siglo, el médico deja de ser la única autoridad en los asuntos de regulación de la vida urbana. Las obras que demandan al ingeniero y lo involucran en la salubridad pública producen una distinción entre "higiene" y "ciencia sanitaria".Throughout its history, Cartagena de Indias, a seaport in the Colombian Caribbean, has been handicapped for not offering salubrious conditions to its people and visitors. The lack of an aqueduct and a sewerage system was an impairment to progress. For nearly forty years (1890-1930 these problems have caused a myriad of medical discourses formulated by scientists, technicians and politicians. Cartagena’s contribution to solve the sanitation problem in cities has consisted in making use of engineers’ knowledge. The construction of urban facilities in the beginning of the twentieth century required a more technical knowledge, one which would advance a comprehensive solution to the water problem, ensure sufficient supply and efficient drainage.

  8. 21st Century Sea-Level Rise in Line with the Paris Accord (United States)

    Jackson, Luke P.; Grinsted, Aslak; Jevrejeva, Svetlana


    As global average sea-level rises in the early part of this century there is great interest in how much global and local sea level will change in the forthcoming decades. The Paris Climate Agreement's proposed temperature thresholds of 1.5°C and 2°C have directed the research community to ask what differences occur in the climate system for these two states. We have developed a novel approach to combine climate model outputs that follow specific temperature pathways to make probabilistic projections of sea-level in a 1.5°C and 2°C world. We find median global sea-level (GSL) projections for 1.5°C and 2°C temperature pathways of 44 and 50 cm, respectively. The 90% uncertainty ranges (5%-95%) are both around 48 cm by 2100. In addition, we take an alternative approach to estimate the contribution from ice sheets by using a semi-empirical GSL model. Here we find median projections of 58 and 68 cm for 1.5°C and 2°C temperature pathways. The 90% uncertainty ranges are 67 and 82 cm respectively. Regional projections show similar patterns for both temperature pathways, though differences vary between the median projections (2-10 cm) and 95th percentile (5-20 cm) for the bulk of oceans using process-based approach and 10-15 cm (median) and 15-25 cm (95th percentile) using the semi-empirical approach.

    The conceptual changes brought by modern physics are important, radical and fascinating, yet they are only vaguely understood by people working outside the field. Exploring the four pillars of modern physics – relativity, quantum mechanics, elementary particles and cosmology – this clear and lively account will interest anyone who has wondered what Einstein, Bohr, Schrödinger and Heisenberg were really talking about. The book discusses quarks and leptons, antiparticles and Feynman diagrams, curved space-time, the Big Bang and the expanding Universe. Suitable for undergraduate students in non-science as well as science subjects, it uses problems and worked examples to help readers develop an understanding of what recent advances in physics actually mean.

  15. Mean relative sea level rise along the coasts of the China Seas from mid-20th to 21st centuries (United States)

    Chen, Nan; Han, Guoqi; Yang, Jingsong


    Mean relative sea level (MRSL) rise has caused more frequent flooding in many parts of the world. The MRSL rise varies substantially from place to place. Here we use tide-gauge data and satellite measurements to examine past MRSL trends for the coasts of the China Seas. We then combine climate model output and satellite observations to provide MRSL projections in the 21st century. The MRSL trend based on tide-gauge data shows substantial regional variations, from 1 to 5 mm/yr. The vertical land motion (VLM) based on altimetry and tide-gauge (ATG) data indicates large land subsidence at some tide-gauge locations, consistent with the Global Positioning Systems (GPS)-based VLM but different significantly from small uplift estimated by a Glacial Isostatic Adjustment (GIA) model, which suggests other important factors causing the VLM instead of the GIA process. When GPS- or ATG-based VLM estimates are used, the projected MRSL rise between 1986-2005 and 2081-2100 at tide-gauge sites varies from 60 to 130 cm under the Representative Concentration Pathway 8.5 (RCP8.5) scenario of the Intergovernmental Panel on Climate Change (IPCC). Our projections are significantly larger than those of IPCC and other literature, as a result of accounting for the land subsidence derived from observations. Steric and dynamic ocean effects and land-ice melt effects are comparable (about 30 cm each) and do not vary much over the tide-gauge locations. The VLM effect varies from -10 to 60 cm. The projections between 1986-2005 and 2081-2100 under RCP4.5 show a similar spatial distribution to that under RCP8.5, with a smaller amount of rise by 18 cm on average for this region.

    Full Text Available In this work we present the result of a study aimed at examining the Italian earthquake sequences that occurred in the area of the central Adriatic sea with the purpose of understanding whether some of them were accompanied by tsunami effects. The motivation for this research was the update and enrichment of the Italian Tsunami Catalogue. The result was that evidence was found for two new cases of earthquake-induced tsunamis: these are the August 1916 Rimini and the October 1930 Ancona events. The bulk of the present research consisted in collecting all the available data on the earthquakes that affected the selected area in the past century and in identifying those potentially capable of generating tsunamis. During the study all the available material was gathered, which includes specific monographs and scientific papers, articles available in contemporary chronicles and in local and national newspapers. The final result of this research will improve our knowledge of the tsunamigenic activity of the central Adriatic sea and contribute to the assessment of the tsunami hazard and risk along these coasts, that especially in the peak season form one of the most densely populated areas of the Italian peninsula with flat and large beaches and water front resorts crowded of tourists.

  18. Keep up or drown: adjustment of western Pacific coral reefs to sea-level rise in the 21st century. (United States)

    van Woesik, R; Golbuu, Y; Roff, G


    Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for vertical reef expansion. Here, we show that Porites microatolls, from reef-flat environments in Palau (western Pacific Ocean), are 'keeping up' with contemporary sea-level rise. Measurements of 570 reef-flat Porites microatolls at 10 locations around Palau revealed recent vertical skeletal extension (78±13 mm) over the last 6-8 years, which is consistent with the timing of the recent increase in sea level. We modelled whether microatoll growth rates will potentially 'keep up' with predicted sea-level rise in the near future, based upon average growth, and assuming a decline in growth for every 1°C increase in temperature. We then compared these estimated extension rates with rates of sea-level rise under four Representative Concentration Pathways (RCPs). Our model suggests that under low-mid RCP scenarios, reef-coral growth will keep up with sea-level rise, but if greenhouse gas concentrations exceed 670 ppm atmospheric CO2 levels and with +2.2°C sea-surface temperature by 2100 (RCP 6.0 W m(-2)), our predictions indicate that Porites microatolls will be unable to keep up with projected rates of sea-level rise in the twenty-first century.

  19. Reconciling past changes in Earth's rotation with 20th century global sea-level rise: Resolving Munk's enigma. (United States)

    Mitrovica, Jerry X; Hay, Carling C; Morrow, Eric; Kopp, Robert E; Dumberry, Mathieu; Stanley, Sabine


    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.

  20. The role of local and external factors in determining the interannual sea level variability of the Adriatic and Black Seas during the 20th century. (United States)

    Scarascia, Luca; Lionello, Piero


    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

  1. The study of the hydrological regime extreme effects of the Caspian Sea during the XX-XXI centuries (United States)

    Yaitskaya, Natalia


    The Caspian Sea - the unique largest enclosed inland body of water on Earth. Significant periodic sea level fluctuations are a typical feature of the sea. In the XIX-XX centuries a number of comprehensive studies of the Caspian Sea was carried out. The results are published in the papers, monographs and climatic atlases. But a number of fundamental questions about the features of the hydrological regime of the Caspian Sea is still open: 1. How does the water circulation change during the level variations? 2. What is the effect of heterogeneity of evaporation from the water surface on the formation of the flow field in the conditions of long-term level changes? 3. How does the water salinity regime change depending on the sea level position, water circulation, river flow and different climatic influences? 4. What is the effect of extreme events (multi-hazards) (ice, storms, destruction of the coasts) on coastal infrastructure? In 2016, the project aims to study hydrological regime extreme effects of the Caspian Sea was supported by the Russian Foundation for Basic Research. Within this project all of the above problems will be solved. Geographic information system "Caspian Sea" for the storage and data processing, including a database of primary oceanographic information for the period of instrumental observations (1897-2013), cartographic database (1921-2011) and tools for multidimensional analysis of spatio-temporal information is the basis of the study. The scheme of interconnected hydrodynamic models (Caspian Sea MODel - Ocean Model - Wind wave model) was developed. The important factors are taken into account in the structure of the models: long-term and seasonal dynamics of the sea waves parameters, new long-term values of evaporation from the shallow waters areas of the Caspian Sea, water circulation. Schemes of general seasonal circulation of the Caspian Sea and the Northern Caspian at different positions of the sea level in XX-XXI centuries using

    Full Text Available No início do século XX a cárie dentária era um problema de saúde pública, na maior parte do planeta. As populações conviviam com infecção, dor, sofrimento e mutilação. A descoberta do efeito preventivo do flúor o transformou, ao longo do século, no principal agente utilizado no enfrentamento da doença em todo o mundo. Em vários países e também no Brasil produtos fluorados têm sido apontados como os principais responsáveis pelo declínio observado na prevalência da cárie. No Brasil, estudos pioneiros realizados nos anos 50 e 60 corroboraram a eficácia preventiva da fluoretação das águas. No período 1986-1996, com 42% da população recebendo água fluoretada, a queda na prevalência da cárie entre crianças de 12 anos de idade foi de 53%. Além da água fluoretada também os dentifrícios são, no presente, amplamente utilizados como veículos para uso do flúor em saúde pública. Neste artigo são abordados aspectos históricos do emprego de flúor, algumas características epidemiológicas da cárie dentária no Brasil, e as perspectivas da continuidade do uso de produtos fluorados nas próximas décadas.In the early of Twentieth Century, dental caries were a big public health problem around world. Infection, pain, suffering and mutilation reached all people. The discovering of preventive effect of fluorine became them, through the Century, the main agent in fighting to disease worldwide. In various countries, including Brazil, fluoridated products have been pointed as main causes for dental caries prevalence decline. Also in Brazil, at the 50s and 60s, the preventive effect of water fluoridation was ratified for some pioneer studies. For the period 1986-1996 epidemiological data shown a significant reduction of 53% in the DMF-T index value at 12-years-old schoolchildren. Water and dentifrices are largely used as vehicle for fluoride in public health actions. In Brazil 42% of population has access to fluoridated

    Abstract Arctic marine mammals (AMMs) are icons of climate change, largely because of their close association with sea ice. However, neither a circumpolar assessment of AMM status nor a standardized metric of sea ice habitat change is available. We summarized available data on abundance and trend for each AMM species and recognized subpopulation. We also examined species diversity, the extent of human use, and temporal trends in sea ice habitat for 12 regions of the Arctic by calculating the dates of spring sea ice retreat and fall sea ice advance from satellite data (1979–2013). Estimates of AMM abundance varied greatly in quality, and few studies were long enough for trend analysis. Of the AMM subpopulations, 78% (61 of 78) are legally harvested for subsistence purposes. Changes in sea ice phenology have been profound. In all regions except the Bering Sea, the duration of the summer (i.e., reduced ice) period increased by 5–10 weeks and by >20 weeks in the Barents Sea between 1979 and 2013. In light of generally poor data, the importance of human use, and forecasted environmental changes in the 21st century, we recommend the following for effective AMM conservation: maintain and improve comanagement by local, federal, and international partners; recognize spatial and temporal variability in AMM subpopulation response to climate change; implement monitoring programs with clear goals; mitigate cumulative impacts of increased human activity; and recognize the limits of current protected species legislation.

  5. Projections of wind-waves in South China Sea for the 21st century (United States)

    Mohammed, Aboobacker; Dykyi, Pavlo; Zheleznyak, Mark; Tkalich, Pavel


    IPCC-coordinated work has been completed within Fourth Assessment Report (AR4) to project climate and ocean variables for the 21st century using coupled atmospheric-ocean General Circulation Models (GCMs). GCMs are not having a wind-wave variable due to a poor grid resolution; therefore, dynamical downscaling of wind-waves to the regional scale is advisable using well established models, such as Wave Watch III (WWIII) and SWAN. Rectilinear-coordinates WWIII model is adapted for the far field comprising the part of Pacific and Indian Oceans centered at the South China Sea and Sunda Shelf (90 °E-130 °E, 10 °S - 26.83 °N) with a resolution of 10' (about 18 km). Near-field unstructured-mesh SWAN model covers Sunda Shelf and centered on Singapore Strait, while reading lateral boundary values from WWIII model. The unstructured grid has the coarsest resolution in the South China Sea (6 to 10 km), medium resolution in the Malacca Strait (1 to 2 km), and the finest resolution in the Singapore Strait (400 m) and along the Singapore coastline (up to 100 m). Following IPCC methodology, the model chain is validated climatologically for the past period 1961-1990 against Voluntary Observing Ship (VOS) data; additionally, the models are validated using recent high-resolution satellite data. The calibrated model chain is used to project waves to 21st century using WRF-downscaled wind speed output of CCSM GCM run for A1FI climate change scenario. To comply with IPCC methodology the entire modeling period is split into three 30-years periods for which statistical parameters are computed individually. Time series of significant wave height at key points near Singapore and on ship sea routes in the SCS are statistically analysed to get probability distribution functions (PDFs) of extreme values. Climatological maps of mean and maximum significant wave height (SWH) values, and mean wave period are built for Singapore region for each 30-yrs period. Linear trends of mean SWH values

    Fortibuoni, Tomaso; Libralato, Simone; Arneri, Enrico; Giovanardi, Otello; Solidoro, Cosimo; Raicevich, Saša


    Historic data on biodiversity provide the context for present observations and allow studying long-term changes in marine populations. Here we present multiple datasets on fish and fisheries of the Adriatic Sea covering the last two centuries encompassing from qualitative observations to standardised scientific monitoring. The datasets consist of three groups: (1) early naturalists' descriptions of fish fauna, including information (e.g., presence, perceived abundance, size) on 255 fish species for the period 1818-1936 (2) historical landings from major Northern Adriatic fish markets (Venice, Trieste, Rijeka) for the period 1902-1968, Italian official landings for the Northern and Central Adriatic (1953-2012) and landings from the Lagoon of Venice (1945-2001) (3) trawl-survey data from seven surveys spanning the period 1948-1991 and including Catch per Unit of Effort data (kgh-1 and/or nh-1) for 956 hauls performed at 301 stations. The integration of these datasets has already demonstrated to be useful to analyse historical marine community changes over time, and its availability through open-source data portal will facilitate analyses in the framework of marine historical ecology.

  9. Uncertainty of the 20th century sea-level rise due to vertical land motion errors (United States)

    Santamaría-Gómez, Alvaro; Gravelle, Médéric; Dangendorf, Sönke; Marcos, Marta; Spada, Giorgio; Wöppelmann, Guy


    Assessing the vertical land motion (VLM) at tide gauges (TG) is crucial to understanding global and regional mean sea-level changes (SLC) over the last century. However, estimating VLM with accuracy better than a few tenths of a millimeter per year is not a trivial undertaking and many factors, including the reference frame uncertainty, must be considered. Using a novel reconstruction approach and updated geodetic VLM corrections, we found the terrestrial reference frame and the estimated VLM uncertainty may contribute to the global SLC rate error by ± 0.2 mmyr-1. In addition, a spurious global SLC acceleration may be introduced up to ± 4.8 ×10-3 mmyr-2. Regional SLC rate and acceleration errors may be inflated by a factor 3 compared to the global. The difference of VLM from two independent Glacio-Isostatic Adjustment models introduces global SLC rate and acceleration biases at the level of ± 0.1 mmyr-1 and 2.8 ×10-3 mmyr-2, increasing up to 0.5 mm yr-1 and 9 ×10-3 mmyr-2 for the regional SLC. Errors in VLM corrections need to be budgeted when considering past and future SLC scenarios.

  15. Centuries of thermal sea-level rise due to anthropogenic emissions of short-lived greenhouse gases. (United States)

    Zickfeld, Kirsten; Solomon, Susan; Gilford, Daniel M


    Mitigation of anthropogenic greenhouse gases with short lifetimes (order of a year to decades) can contribute to limiting warming, but less attention has been paid to their impacts on longer-term sea-level rise. We show that short-lived greenhouse gases contribute to sea-level rise through thermal expansion (TSLR) over much longer time scales than their atmospheric lifetimes. For example, at least half of the TSLR due to increases in methane is expected to remain present for more than 200 y, even if anthropogenic emissions cease altogether, despite the 10-y atmospheric lifetime of this gas. Chlorofluorocarbons and hydrochlorofluorocarbons have already been phased out under the Montreal Protocol due to concerns about ozone depletion and provide an illustration of how emission reductions avoid multiple centuries of future TSLR. We examine the "world avoided" by the Montreal Protocol by showing that if these gases had instead been eliminated in 2050, additional TSLR of up to about 14 cm would be expected in the 21st century, with continuing contributions lasting more than 500 y. Emissions of the hydrofluorocarbon substitutes in the next half-century would also contribute to centuries of future TSLR. Consideration of the time scales of reversibility of TSLR due to short-lived substances provides insights into physical processes: sea-level rise is often assumed to follow air temperature, but this assumption holds only for TSLR when temperatures are increasing. We present a more complete formulation that is accurate even when atmospheric temperatures are stable or decreasing due to reductions in short-lived gases or net radiative forcing.

  17. Probabilistic 21st and 22nd Century Sea-Level Projections at a Global Network of Tide-Gauge Sites (United States)

    Kopp, Robert E.; Horton, Radley M.; Little, Christopher M.; Mitrovica, Jerry X.; Oppenheimer, Michael; Rasmussen, D. J.; Strauss, Benjamin H.; Tebaldi, Claudia


    Sea-level rise due to both climate change and non-climatic factors threatens coastal settlements, infrastructure, and ecosystems. Projections of mean global sea-level (GSL) rise provide insufficient information to plan adaptive responses; local decisions require local projections that accommodate different risk tolerances and time frames and that can be linked to storm surge projections. Here we present a global set of local sea-level (LSL) projections to inform decisions on timescales ranging from the coming decades through the 22nd century. We provide complete probability distributions, informed by a combination of expert community assessment, expert elicitation, and process modeling. Between the years 2000 and 2100, we project a very likely (90% probability) GSL rise of 0.5–1.2?m under representative concentration pathway (RCP) 8.5, 0.4–0.9?m under RCP 4.5, and 0.3–0.8?m under RCP 2.6. Site-to-site differences in LSL projections are due to varying non-climatic background uplift or subsidence, oceanographic effects, and spatially variable responses of the geoid and the lithosphere to shrinking land ice. The Antarctic ice sheet (AIS) constitutes a growing share of variance in GSL and LSL projections. In the global average and at many locations, it is the dominant source of variance in late 21st century projections, though at some sites oceanographic processes contribute the largest share throughout the century. LSL rise dramatically reshapes flood risk, greatly increasing the expected number of “1-in-10” and “1-in-100” year events.

  20. Critical Beach Habitat for Hawaiian Green Sea Turtle Endangered Before Mid-Century (United States)

    Burstein, J. T.; Fletcher, C. H., III; Dominique Tavares, K.


    Many Hawaiian beaches provide critical habitat for the Hawaiian Green Sea Turtle (Chelonia Mydas). However, sea level rise drives beaches and dunes to migrate landward where they may encounter roads and other types of developed lands. Where developed lands are threatened by coastal erosion, defined as a distance of 20 ft (6.1 m) by state rules, property owners are eligible to apply for an emergency permit. These have historically led to coastal armoring. Seawalls and revetments on chronically receding shorelines cause permanent beach loss by restricting sand supply to the beach in front of the sea wall, as well as to beaches adjacent to the restrictive structure (flanking). This study focuses on four primary beach habitats along the North Shore of Oahu, Hawai'i: Waimea, Haleiwa, Kawailoa, and Mokuleia. We utilize GIS techniques to apply spatial analysis of nesting and basking locations collected from the National Oceanic Atmospheric Administration (NOAA). We then estimate the number of homes and the length of shoreline threatened by coastal armoring for 0 m, 0.17 m, 0.32 m, 0.60 m, and 0.98 m of sea-level rise. We demonstrate that 0.17 m of sea level rise impacts 31% of all beach front homes, and 4.6 km of shoreline, or 21% of the total shoreline. An increase to 0.32 m of sea level rise impacts 42% of all beach front homes, and 5.8 km of shoreline, or 31% of the total shoreline. The upper bound of the most recent sea level rise projection by the International Panel on Climate Change (IPCC RCP 8.5) affirms that 0.17 m of sea level rise may be reached by 2030, and 0.32 m by 2050. This sea level projection is a "worst-case" under IPCC-AR5, however, Sweet et al. (2017) depicts this as an "Intermediate" scenario on the basis of faster than expected mass loss by Greenland and Antarctica ice sheets, and rapid heat uptake and thermal expansion by the world's oceans. We conclude that the impacts of sea level rise and reactive coastal armoring currently endanger critical

  1. Contemporary sea level rise. (United States)

    Cazenave, Anny; Llovel, William


    Measuring sea level change and understanding its causes has considerably improved in the recent years, essentially because new in situ and remote sensing observations have become available. Here we report on most recent results on contemporary sea level rise. We first present sea level observations from tide gauges over the twentieth century and from satellite altimetry since the early 1990s. We next discuss the most recent progress made in quantifying the processes causing sea level change on timescales ranging from years to decades, i.e., thermal expansion of the oceans, land ice mass loss, and land water-storage change. We show that for the 1993-2007 time span, the sum of climate-related contributions (2.85 +/- 0.35 mm year(-1)) is only slightly less than altimetry-based sea level rise (3.3 +/- 0.4 mm year(-1)): approximately 30% of the observed rate of rise is due to ocean thermal expansion and approximately 55% results from land ice melt. Recent acceleration in glacier melting and ice mass loss from the ice sheets increases the latter contribution up to 80% for the past five years. We also review the main causes of regional variability in sea level trends: The dominant contribution results from nonuniform changes in ocean thermal expansion.

  2. Effective inundation of continental United States communities with 21st century sea level rise

    Directory of Open Access Journals (Sweden)

    Kristina A. Dahl


    Full Text Available Recurrent, tidally driven coastal flooding is one of the most visible signs of sea level rise. Recent studies have shown that such flooding will become more frequent and extensive as sea level continues to rise, potentially altering the landscape and livability of coastal communities decades before sea level rise causes coastal land to be permanently inundated. In this study, we identify US communities that will face effective inundation—defined as having 10% or more of livable land area flooded at least 26 times per year—with three localized sea level rise scenarios based on projections for the 3rd US National Climate Assessment. We present these results in a new, online interactive tool that allows users to explore when and how effective inundation will impact their communities. In addition, we identify communities facing effective inundation within the next 30 years that contain areas of high socioeconomic vulnerability today using a previously published vulnerability index. With the Intermediate-High and Highest sea level rise scenarios, 489 and 668 communities, respectively, would face effective inundation by the year 2100. With these two scenarios, more than half of communities facing effective inundation by 2045 contain areas of current high socioeconomic vulnerability. These results highlight the timeframes that US coastal communities have to respond to disruptive future inundation. The results also underscore the importance of limiting future warming and sea level rise: under the Intermediate-Low scenario, used as a proxy for sea level rise under the Paris Climate Agreement, 199 fewer communities would be effectively inundated by 2100.

  5. Future sea ice conditions in Western Hudson Bay and consequences for polar bears in the 21st century. (United States)

    Castro de la Guardia, Laura; Derocher, Andrew E; Myers, Paul G; Terwisscha van Scheltinga, Arjen D; Lunn, Nick J


    The primary habitat of polar bears is sea ice, but in Western Hudson Bay (WH), the seasonal ice cycle forces polar bears ashore each summer. Survival of bears on land in WH is correlated with breakup and the ice-free season length, and studies suggest that exceeding thresholds in these variables will lead to large declines in the WH population. To estimate when anthropogenic warming may have progressed sufficiently to threaten the persistence of polar bears in WH, we predict changes in the ice cycle and the sea ice concentration (SIC) in spring (the primary feeding period of polar bears) with a high-resolution sea ice-ocean model and warming forced with 21st century IPCC greenhouse gas (GHG) emission scenarios: B1 (low), A1B (medium), and A2 (high). We define critical years for polar bears based on proposed thresholds in breakup and ice-free season and we assess when ice-cycle conditions cross these thresholds. In the three scenarios, critical years occur more commonly after 2050. From 2001 to 2050, 2 critical years occur under B1 and A2, and 4 under A1B; from 2051 to 2100, 8 critical years occur under B1, 35 under A1B and 41 under A2. Spring SIC in WH is high (>90%) in all three scenarios between 2001 and 2050, but declines rapidly after 2050 in A1B and A2. From 2090 to 2100, the mean spring SIC is 84 (±7)% in B1, 56 (±26)% in A1B and 20 (±13)% in A2. Our predictions suggest that the habitat of polar bears in WH will deteriorate in the 21st century. Ice predictions in A1B and A2 suggest that the polar bear population may struggle to persist after ca. 2050. Predictions under B1 suggest that reducing GHG emissions could allow polar bears to persist in WH throughout the 21st century. © 2013 John Wiley & Sons Ltd.

  7. "The necessity for better bodies to perpetuate our institutions, insure a higher development of the individual, and advance the conditions of the race." Physical culture and the formation of the self in the late nineteenth and early twentieth century USA. (United States)

    Martschukat, Jürgen


    This article explores the significance of sports and physical exercise in the turn-of-the-century culture and society of the U.S. It depicts how physical fitness became a decisive feature of collective and individual self-perception and was understood as being at the core of a successful shaping of both the self and of the American body politic. I concentrate in particular on paradigms and strategies of human resources management to exemplify the overarching significance of physical fitness as it established itself at the heart of the USA's enterprise culture that began to emerge in the later nineteenth century. American peculiarities will be considered, alongside ties and allusions to European, and particularly British, developments.

    Joseph Park


    Full Text Available South Florida encompasses a dynamic confluence of urban and natural ecosystems strongly connected to ocean and freshwater hydrologic forcings. Low land elevation, flat topography and highly transmissive aquifers place both communities at the nexus of environmental and ecological transformation driven by rising sea level. Based on a local sea level rise projection, we examine regional inundation impacts and employ hydrographic records in Florida Bay and the southern Everglades to assess water level exceedance dynamics and landscape-relevant tipping points. Intrinsic mode functions of water levels across the coastal interface are used to gauge the relative influence and time-varying transformation potential of estuarine and freshwater marshes into a marine-dominated environment with the introduction of a Marsh-to-Ocean transformation index (MOI.

  10. The Demographic Characteristics of the Tribes of the Black Sea Region in the first half of the XIX century

    Aleksandr A. Cherkasov


    Full Text Available The social class structure of the Black sea tribes, the resettlement area which was the territory from Anapa to the river Bzyb, has not yet become a subject of research in the historiography. Natukhaitsy and shapsugs of Adygeyan tribe, ubykhs, and also jikis of Abaza tribe lived in the territory during the first half of the XIX century. The data sources on the population in this territory at a specified time are contradictory, thus practically does not reflect the proportion of estates. The authors attracted as sources the statistical materials of 1800-1860-ies, including those published in the modern period on the Abkhazia (Abaza tribe and the Kuban. By the comparison of the different sources there was made an attempt to calculate the proportion of the population on the estates, namely: the proportion of princes, nobles, free inhabitants, dependent inhabitants, slaves separately for coastal and mountain societies. In addition there were attracted the sources of personal origin – diaries and memoirs, the works of Abkhazians who lived among travelers, and, of course, the scientific literature. The authors used the methods of demographic statistics for reconstruction of the population of the tribes of the Black sea region due to the presence of incomplete data on the number of classes. In conclusion the research provides with the accumulated statistical data on total population, population class and gender.

  11. On the mechanisms of late 20th century sea-surface temperature trends over the Antarctic Circumpolar Current (United States)

    Kravtsov, Sergey; Kamenkovich, Igor; Hogg, Andrew M.; Peters, John M.


    The Antarctic Circumpolar Current (ACC), with its associated three-dimensional circulation, plays an important role in global climate. This study concentrates on surface signatures of recent climate change in the ACC region and on mechanisms that control this change. Examination of climate model simulations shows that they match the observed late 20th century sea-surface temperature (SST) trends averaged over this region quite well, despite underestimating the observed surface-wind increases. Such wind increases, however, are expected to lead to significant cooling of the region, contradicting the observed SST trends. Motivated by recent theories of the ACC response to variable wind and radiative forcing, the authors used two idealized models to assess contributions of various dynamical processes to the SST evolution in the region. In particular, a high-resolution channel model of the ACC responds to increasing winds by net surface ACC warming due to enhanced mesoscale turbulence and associated heat transports in the mixed layer. These fluxes, modeled, in a highly idealized fashion, via increased lateral surface mixing in a coarse-resolution hybrid climate model, substantially offset zonally non-uniform surface cooling due to air-sea flux and Ekman-transport anomalies. These results suggest that the combination of these opposing effects must be accounted for when estimating climate response to any external forcing in the ACC region.

    In this study we analyse the effect of both foreign and domestic technological innovation on Total Factor Productivity (TFP) for Spain in the second half of the XXth century. For this purpose we estimate an extended version of Coe and Helpman (1995) model, in which the foreign and domestic stock of knowledge is measured using the expenditure on R and D. Our results suggest that the entrance of foreign technology had a positive and significant effect on the Spanish TFP. We also find that the domestic knowledge had a positive and significant effect, although this effect is always smaller than the effect associated to foreign knowledge. (Author)

  14. Century-scale high-resolution black carbon records in sediment cores from the South Yellow Sea, China (United States)

    Xu, Xiaoming; Hong, Yuehui; Zhou, Qianzhi; Liu, Jinzhong; Yuan, Lirong; Wang, Jianghai


    Black carbon (BC) has received increasing attention in the last 20 years because it is not only an absorbent of toxic pollutants but also a greenhouse substance, preserving fire-history records, and more importantly, acting as an indicator of biogeochemical cycles and global changes. By adopting an improved chemothermal oxidation method (WXY), this study reconstructed the century-scale high-resolution records of BC deposition from two fine-grained sediment cores collected from the Yellow Sea Cold Water Mass in the South Yellow Sea. The BC records were divided into five stages, which exhibited specific sequences with three BC peaks at approximately 1891, 1921, and 2007 AD, representing times at which the first heavy storms appeared just after the termination of long-term droughts. The significant correlation between the times of the BC peaks in the cores and heavy storms in the area of the Huanghe (Yellow) River demonstrated that BC peaks could result from markedly strengthened sedimentation due to surface runoff, which augmented the atmospheric deposition. Stable carbon isotope analysis indicated that the evident increase in carbon isotope ratios of BC in Stage 5 might have resulted from the input of weathered rock-derived graphitic carbon cardinally induced by the annual anthropogenic modulation of water-borne sediment in the Huanghe River since 2005 AD. Numerical calculations demonstrated that the input fraction of graphitic carbon was 22.97% for Stage 5, whereas no graphitic carbon entered during Stages 1 and 3. The obtained data provide new and important understanding of the source-sink history of BC in the Yellow Sea.

  16. "Pittura Romeica" in Italy: Artistic transfers across the Adriatic sea (18th - 19th centuries

    Directory of Open Access Journals (Sweden)

    Eugenia Drakopoulou


    Full Text Available The complex historical reality of the Adriatic region, an area located even today on the borderline between East and West, is reflected in the works of religious painting and in the painters’ geographical movements. The art of Orthodox regions was mainly influenced by Venice, but also by the rest of Italy, and, as a result, a unique art emerged in the Ionian Islands, which remained under Venetian control until the end of the eighteenth century. In the course of the eighteenth century, political and economic conditions contributed to the growth of the Orthodox communities in Italy. Their members were interested in the art of the country where they lived and prospered, but they simultaneously wished to preserve the “pittura romeica” in the decorations of churches and in the icons used for their personal worship. From Naples to the cosmopolitan Trieste, Orthodox painters, coming mainly from the Ionian Islands, produced artworks which were adapted to the new surroundings, thereby making the Adriatic region once again a privileged area for cultural exchanges.

  18. ['The spirit has left the bottle': the medieval Arabic physician 'Abd al-Latĭf ibn Yŭsuf al-Baghdădĭ: his medical work and his bizarre affiliation with twentieth-century spiritualism]. (United States)

    Joosse, N Peter


    The Arabic physician 'Abd al-Latĭf ibn Yŭsuf al-Baghdădĭ, lived at the crossroads of the twelfth and the thirteenth century. His unbridled curiosity and his unquenchable thirst for knowledge of any kind brought him to far-away countries and regions and put him in contact with all sorts and conditions of people. The great Egyptian famine of the years 1200-1202 enabled him to study and examine thousands of human cadavers and skeletons at first hand. This led to a new understanding of the anatomical structure of the human body, and rejected the more or less antiquated ideas of the Greek doctor Galen of Pergamum. However, 'Abd al-Latĭf's vision was granted only a short life. After his death, his discovery sank into oblivion and as a consequence it was never again mentioned in Arabic medical manuals. From then on the Arabic physicians once more referred to the anatomical data which were developed and taught by Galen. Relatively few specimens of his remaining medical work were preserved for posterity. However, his Book of the two advices (or: K. al-Nasĭhatain) is of the utmost importance as a source for the medical thinking and the medical treatment in the late twelfth and the early thirteenth century A.D. During the years following World War I, 'Abd al-Latĭf's name reappeared within the spiritualistic movement in England. He became known as Abduhl Latif the great Persian physician and acted as a control of mediums. Until the late sixties, he practised the art of healing as the head of a medical mission somewhere in the Spheres.

  19. Atmospheric lead fallout over the last century recorded in Gulf of Lions sediments (Mediterranean Sea)

    International Nuclear Information System (INIS)

    Miralles, J. . E-mail; Veron, A.J.; Radakovitch, O.; Deschamps, P.; Tremblay, T.; Hamelin, B.


    Six marine sediment cores from the Gulf of Lions continental slope (700-1700 m water depth) were analyzed for stable lead isotopes and 21 Pb geochronology in order to reconstruct lead atmospheric fallout pattern during the last century. The detrital lead contribution is 25 μg g -1 and the mean sediment anthropogenic inventory is 110 ± 7 μg cm -2 , a little bit higher than atmospheric deposition estimate. Anthropogenic lead accumulation in sediments peaked in early 1970s (1973 ± 2) in agreement with lead emissions features. For the period 1986-1997, the sediment signal also reflect the decrease of atmospheric lead described by independent atmospheric fallout investigations. The anthropogenic Pb deposition in the late 1990s was similar to the 1950s deposition, attesting thus of the output of European environmental policies

    Directory of Open Access Journals (Sweden)



    Full Text Available Based on interviews, autobiographical materials, and archival documents from the mid-twentieth century, there is an attempt made to find answers to the question of how much the collectivization of agriculture in Poland broke young people’s emotional and economic ties with the family and their farms. The government’s decision on the necessity of making agriculture collective as soon as possible liberated the young from the previous obligation to inherit farms and allowed them to work outside agriculture without risking parental dissatisfaction. The establishment of production cooperatives enabled them to continue their studies in secondary school and made the dreams of those young people come true, namely to live in the city. It was much easier because the developing industries needed labour. This way the idea of patrimony, developed throughout decades as the sole basis of life of the peasant child was overthrown. Thus, with the move to the city such traditional peasant values as the authority of the father, piety, respect for bread faded away. The situation led to numerous conflicts with the family remaining in the countryside.

    Full Text Available Em quatro escolas superiores de agricultura estudadas o percentual de mulheres no corpo discente ou no corpo docente é estatisticamente desprezível nas décadas de 1930 e 1940. Apesar disso, do ponto de vista dos estudos de gênero e da história das ciências, é importante compreender essa presença para entender e reconhecer o papel das mulheres na sociedade e em particular no meio científico. Nosso propósito não foi o de realizar um balanço aprofundado sobre a carreira seguida pelas engenheiras agrônomas. Outrossim, reunimos o que falavam sobre elas as poesias, os ofícios, algumas fotos e figuras, relacionando essas representações ao processo de institucionalização das ciências agrícolas no Brasil no período.Our research on the historical trajectory of four Brazilian agricultural schools in the thirties and forties of the twentieth century does not show a significant number of women in the profession. Nevertheless, rethinking these data, inspired by the history of science and gender studies, it is possible to understand the meanings, and the role played of those women within society, and in the scientific milieu. We collected and analyzed speeches, poetry, official documents, images, and photos, which led to a reflection on these representations, as well as the process of institutionalization of agricultural science.

  2. Wonders with the Sea: Rachel Carson’s Ecological Aesthetic and the Mid-Century Reader

    Directory of Open Access Journals (Sweden)

    Amanda Hagood


    Full Text Available Recent scholarship on the work of the great nature writer, Rachel Carson, posits that her landmark book, Silent Spring (1962—often credited with igniting the modern environmental movement—is best understood in the context of her earlier, extraordinarily popular publications on the natural history of the oceans, which helped establish her as a talented and trustworthy translator of scientific concepts into literary prose. This essay builds upon that idea, showing how Carson’s The Sea Around Us (1951 and The Edge of the Sea (1955 not only shaped public understandings of ocean ecology, but also spurred a public passion for all things oceanographic, best embodied in a wave of “Carsonalia”—consumer items and experiences ranging from hats, to Book of the Month Club editions, to liner notes for the NBC Symphony’s recording of Debussy’s La Mer. While these items inspired and expressed the “sense of wonder” that was critical to Carson’s ecological aesthetic, I argue, they also subsumed the new “frontier” of the world’s oceans into the technological imperialism of the post-World War II United States. As new technologies allowed military and scientific researchers to see deeper into the oceanic depths than ever before, images of the open ocean were domesticated through consumer markets into viewable, readable, and even wearable forms. This commodification of the ocean, and of Carson’s ecocentric message, both enabled and frustrated her attempts to promote ecological literacy. Yet they also reveal much about our contemporary relationship to the world’s oceans, which remain sites of both enduring wonder and extraordinary exploitation.

  4. The Different Western Perception of the Oriental Moor in the Renaissance and the Twentieth Century: Shakespeare's Othello and Tayeb Salih's Season of Migration to the North: A Post-Colonial Critique

    Directory of Open Access Journals (Sweden)

    Hussein A. Alhawamdeh


    Full Text Available This paper comparatively explores the different experience of the Muslim Orient - namely, Othello in Shakespeare's Othello (1604 and Mustafa Saeed and the narrator in Salih's Season of Migration to the North (1966 - in the West. It aims at relocating the transformation of the discourse of Orientalism from Renaissance, as represented by Shakespeare's Othello, to the post-eighteenth century, as represented by Salih's Season of Migration to the North. By contrasting the West and the Crescent, from power relations' vantage, this study highlights the historical difference of the western perception of the Orient from a colonizer, liberator, and guide to the West, as in Shakespeare's Othello, to a colonized subject, as in the characters of Mustafa Saeed and the narrator in Season of Migration. This paper bridges the gap left by modern scholarship which either focuses only on applying post-colonial theory on Salih's novel or neglects its resonance to Shakespeare's Othello in terms of power relations' vantage. Salih's novel laments, rather than deconstructs, the Renaissance Shakespearean powerful Moor, as represented by Othello in Shakespeare's Othello.

    Sale, Peter F; Agardy, Tundi; Ainsworth, Cameron H; Feist, Blake E; Bell, Johann D; Christie, Patrick; Hoegh-Guldberg, Ove; Mumby, Peter J; Feary, David A; Saunders, Megan I; Daw, Tim M; Foale, Simon J; Levin, Phillip S; Lindeman, Kenyon C; Lorenzen, Kai; Pomeroy, Robert S; Allison, Edward H; Bradbury, R H; Corrin, Jennifer; Edwards, Alasdair J; Obura, David O; Sadovy de Mitcheson, Yvonne J; Samoilys, Melita A; Sheppard, Charles R C


    Over 1.3 billion people live on tropical coasts, primarily in developing countries. Many depend on adjacent coastal seas for food, and livelihoods. We show how trends in demography and in several local and global anthropogenic stressors are progressively degrading capacity of coastal waters to sustain these people. Far more effective approaches to environmental management are needed if the loss in provision of ecosystem goods and services is to be stemmed. We propose expanded use of marine spatial planning as a framework for more effective, pragmatic management based on ocean zones to accommodate conflicting uses. This would force the holistic, regional-scale reconciliation of food security, livelihoods, and conservation that is needed. Transforming how countries manage coastal resources will require major change in policy and politics, implemented with sufficient flexibility to accommodate societal variations. Achieving this change is a major challenge - one that affects the lives of one fifth of humanity. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

  6. Status of biodiversity in the Baltic Sea. (United States)

    Ojaveer, Henn; Jaanus, Andres; Mackenzie, Brian R; Martin, Georg; Olenin, Sergej; Radziejewska, Teresa; Telesh, Irena; Zettler, Michael L; Zaiko, Anastasija


    The brackish Baltic Sea hosts species of various origins and environmental tolerances. These immigrated to the sea 10,000 to 15,000 years ago or have been introduced to the area over the relatively recent history of the system. The Baltic Sea has only one known endemic species. While information on some abiotic parameters extends back as long as five centuries and first quantitative snapshot data on biota (on exploited fish populations) originate generally from the same time, international coordination of research began in the early twentieth century. Continuous, annual Baltic Sea-wide long-term datasets on several organism groups (plankton, benthos, fish) are generally available since the mid-1950s. Based on a variety of available data sources (published papers, reports, grey literature, unpublished data), the Baltic Sea, incl. Kattegat, hosts altogether at least 6,065 species, including at least 1,700 phytoplankton, 442 phytobenthos, at least 1,199 zooplankton, at least 569 meiozoobenthos, 1,476 macrozoobenthos, at least 380 vertebrate parasites, about 200 fish, 3 seal, and 83 bird species. In general, but not in all organism groups, high sub-regional total species richness is associated with elevated salinity. Although in comparison with fully marine areas the Baltic Sea supports fewer species, several facets of the system's diversity remain underexplored to this day, such as micro-organisms, foraminiferans, meiobenthos and parasites. In the future, climate change and its interactions with multiple anthropogenic forcings are likely to have major impacts on the Baltic biodiversity.

  7. Les nouvelles frontières des Jeux Anthropologiques de Saint-Louis The new frontiers of the St. Louis Anthropological Games: sport and the racialization of the American nation at the onset of the twentieth century

    Directory of Open Access Journals (Sweden)

    Fabrice Delsahut


    Full Text Available En 1904, à Saint-Louis, les compétitions olympiques furent perdues dans le chaos d’une exposition universelle, la Louisiana Purchase Exposition. Les Jeux olympiques ne purent échapper à la montée des idéologies racistes du début du xxe siècle et ils contribuèrent à discuter du mérite athlétique des différentes races. Malgré l’esprit universel qu’on voulait y voir présider, Saint-Louis refléta longtemps les préjugés raciaux de leurs organisateurs. Ces derniers mirent aussi sur pied des compétitions spéciales, appelées pour l’occasion « journées anthropologiques », réservées à ceux que l’Amérique ségrégationniste du moment considérait comme des sous-hommes. À partir de ces faits, nous essaierons de montrer comment les sciences du sport et l’anthropologie naissante se mirent ensemble au service de causes aussi discutables que la hiérarchisation raciale et le droit à la colonisation et contribuèrent grandement à la naissance d’une nation américaine mettant le sport au cœur de sa constitution. L’impact des race studies sur les façons de penser le sport ne furent pas, contrairement à ce que s’efforcèrent de faire croire les différents présidents du C.I.O. au cours des décennies suivantes, qu’un simple avatar du mouvement olympique. Enfin, nous verrons l’influence de ce spectacle athlétique interracial en dehors des États-Unis qui a assurément permis d’élaborer une certaine perception de l’altérité et limiter l’insertion des peuples autochtones dans le tissu sportif mondial.In 1904, in St. Louis, the Olympic competitions were lost in the chaos of a World Fair called the Louisiana Purchase Exposition.

    Pavel V. Fedorov


    This article is dedicated to analysing the historical background of the process of colonization Murman coast of the Barents Sea at the second half of the 19th and the begining 20th century. It consider two different interpretations of the history of colonization. One of them is the process of checking the Murman coast as a result of Russia imposed Western European initiatives. Another interpretation associates colonization with traditional process of the Russian presence on Murman.

    Full Text Available O objetivo deste artigo é o de analisar como o assassinato de um homossexual foi tratado em um tribunal da Capital da República em meados do século XX. Os autos criminais podem revelar aspectos significativos sobre a aplicação do direito nas instâncias judiciais. Ressaltamos como a cultura jurídico-penal no país continuou reproduzindo os mesmos padrões socioculturais das culturas jurídico-penais ocidentais; em última instância, condenando o prazer ou pelo menos determinadas formas de senti-lo. Da mesma forma, inferimos que, por intermédio da legalidade processual, se reprimiu determinado comportamento sexual, já que a legalidade formal não preceituava a homossexualidade como crime.The aim of this paper is to analyze how the murder of a homosexual was treated at a court in the capital of the Republic of Brazil in mid-twentieth century. Although intrinsically individualizing, criminal records reveal significant aspects on the application of the law in judicial court instances. The juridical and penal culture of the period reproduced continually the same social and cultural standards of Western juridical and penal culture in spite of the contemporary accumulation of knowledge. In other words, pleasure was condemned or, at least, certain forms of feeling pleasure, especially those which directly impaired procreation. Results show that through juridical legality certain types of sexual behavior were repressed, since the law itself did not consider homosexuality a crime.

    Full Text Available Se examina en un caso concreto la afirmación general de la importancia de las redes de comunicación y la movilidad de las cosas para la ciencia. De qué forma esto jugó un papel relevante en las investigaciones sobre la embriología de ciertas especies de armadillos a principios del siglo XX? Como intentamos mostrar, el acceso a las hembras preñadas de esas especies silvestres y los tiempos en el transporte hasta el laboratorio fueron cuestiones substanciales en los inicios de esas investigaciones. Las estrategias para obtener muestras en el campo y la temporalidad de ciertos fenómenos, los circuitos comerciales en los que participan los organismos estudiados y su trasformación en el laboratorio permiten vislumbrar aspectos de cómo trabajaron y qué problemas enfrentaron esos científicos.The article examines the general affirmation that communication networks and mobility are important to science by examining how these factors played a relevant role in one specific case, that is, research on the embryology of certain species of armadillos in the early twentieth century. As we show, access to pregnant females of the species and transport time from the wild to the laboratory were significant issues in the early days of such research. The strategies used to obtain field samples, the temporality of certain phenomena, the commercial circuits of which the organisms under study were a part, and the transformations they underwent in the laboratory all afford a glimpse at some aspects of how these scientists approached their work and what problems they faced in producing new knowledge.

  12. Can uncertainties in sea ice albedo reconcile patterns of data-model discord for the Pliocene and 20th/21st centuries? (United States)

    Howell, Fergus W.; Haywood, Alan M.; Dolan, Aisling M.; Dowsett, Harry J.; Francis, Jane E; Hill, Daniel J.; Pickering, Steven J.; Pope, James O.; Salzmann, Ulrich; Wade, Bidget S


    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.

  13. Most atolls will be uninhabitable by the mid-21st century because of sea-level rise exacerbating wave-driven flooding (United States)

    Storlazzi, Curt; Gingerich, Stephen B.; van Dongeren, Ap; Cheriton, Olivia; Swarzenski, Peter W.; Quataert, Ellen; Voss, Clifford I.; Field, Donald W.; Annamalai, Hariharasubramanian; Piniak, Greg A.; McCall, Robert T.


    Sea levels are rising, with the highest rates in the tropics, where thousands of low-lying coral atoll islands are located. Most studies on the resilience of these islands to sea-level rise have projected that they will experience minimal inundation impacts until at least the end of the 21st century. However, these have not taken into account the additional hazard of wave-driven overwash or its impact on freshwater availability. We project the impact of sea-level rise and wave-driven flooding on atoll infrastructure and freshwater availability under a variety of climate change scenarios. We show that, on the basis of current greenhouse gas emission rates, the nonlinear interactions between sea-level rise and wave dynamics over reefs will lead to the annual wave-driven overwash of most atoll islands by the mid-21st century. This annual flooding will result in the islands becoming uninhabitable because of frequent damage to infrastructure and the inability of their freshwater aquifers to recover between overwash events. This study provides critical information for understanding the timing and magnitude of climate change impacts on atoll islands that will result in significant, unavoidable geopolitical issues if it becomes necessary to abandon and relocate low-lying island states.

  14. North Atlantic 20th century multidecadal variability in coupled climate models: sea surface temperature and ocean overturning circulation

    Directory of Open Access Journals (Sweden)

    I. Medhaug


    Full Text Available Output from a total of 24 state-of-the-art Atmosphere-Ocean General Circulation Models is analyzed. The models were integrated with observed forcing for the period 1850–2000 as part of the Intergovernmental Panel on Climate Change (IPCC Fourth Assessment Report. All models show enhanced variability at multi-decadal time scales in the North Atlantic sector similar to the observations, but with a large intermodel spread in amplitudes and frequencies for both the Atlantic Multidecadal Oscillation (AMO and the Atlantic Meridional Overturning Circulation (AMOC. The models, in general, are able to reproduce the observed geographical patterns of warm and cold episodes, but not the phasing such as the early warming (1930s–1950s and the following colder period (1960s–1980s. This indicates that the observed 20th century extreme in temperatures are due to primarily a fortuitous phasing of intrinsic climate variability and not dominated by external forcing. Most models show a realistic structure in the overturning circulation, where more than half of the available models have a mean overturning transport within the observed estimated range of 13–24 Sverdrup. Associated with a stronger than normal AMOC, the surface temperature is increased and the sea ice extent slightly reduced in the North Atlantic. Individual models show potential for decadal prediction based on the relationship between the AMO and AMOC, but the models strongly disagree both in phasing and strength of the covariability. This makes it difficult to identify common mechanisms and to assess the applicability for predictions.

  20. Population and society in twentieth-century Southeast Asia. (United States)

    Hirschman, C


    The historical demographic analysis in this article is a revision of a paper presented at the Conference of the Northwest Regional Consortium for Southeast Asian Studies in 1988 at the University of Oregon. The author takes the view that fertility has remained high in the Southeast Asian region due to the dynamics of colonialism and the reinforcement of traditional society. Industrialization, urbanization, and advancing education was not favored by colonial policy. The shift to planting cash crops was labor-intensive work which reinforced large families. The fertility decline after the 1960s is attributed to population pressure and the lower limits of land and production per family. Incentives for smaller families are identified as the expansion of mass education, increased consumer aspirations, and opportunities for modern sector employment. The impact of population growth is viewed as multidimensional and indicative of the conflicts between resources, obligations, and aspirations. The historical record in Southeast Asia reveals a population shortage and the risk of losing the minimum supply of labor necessary for a subsistence economy. Traditional local authorities were in need of men for waging war and producing an economic surplus. Colonial administrators imported cheap labor. As mortality declined and population increased, the societal response was migration, usually to frontier areas. New zones of wet rice production were created in lower Burma, central Siam, and Cochin China due to increased demand. Other survival strategies are identified as infinite land subdivision and multiple job holding in the off-season. Densely populated areas appeared to have lower fertility. Over the past 20 years the strategy appears to have been lower fertility coupled with acceptance of family planning, higher female educational attainment, and higher age at marriage. Southeast Asian patterns are considered indicative of the impact of wars, crises, and economic change on demographic processes and of the demographic impact of changes in population size, density, and structure on social, political, and economic outcomes.

  2. Twentieth century surge of excess adult male mortality (United States)

    Beltrán-Sánchez, Hiram; Finch, Caleb E.; Crimmins, Eileen M.


    Using historical data from 1,763 birth cohorts from 1800 to 1935 in 13 developed countries, we show that what is now seen as normal—a large excess of female life expectancy in adulthood—is a demographic phenomenon that emerged among people born in the late 1800s. We show that excess adult male mortality is clearly rooted in specific age groups, 50–70, and that the sex asymmetry emerged in cohorts born after 1880 when male:female mortality ratios increased by as much as 50% from a baseline of about 1.1. Heart disease is the main condition associated with increased excess male mortality for those born after 1900. We further show that smoking-attributable deaths account for about 30% of excess male mortality at ages 50–70 for cohorts born in 1900–1935. However, after accounting for smoking, substantial excess male mortality at ages 50–70 remained, particularly from cardiovascular disease. The greater male vulnerability to cardiovascular conditions emerged with the reduction in infectious mortality and changes in health-related behaviors. PMID:26150507

  7. Mechanical engineering prospects at the end of the twentieth century

    International Nuclear Information System (INIS)

    Garcia Rodriguez, A.


    The future of Mechanical Engineering in Spain appears to be very bright indeed. This conclusion has been derived from an analysis of its evolution in the last 20 years, a period which has seen the development of excellent working universities, research organizations and centres, and in industry. The initial delay in Spain's industrialization process, as compared to other European countries, has led to the situation where we do not have multinational companies which are purely Spanish-owned in these areas. Nevertheless, a process of globalization of the industry is clearly under way, not only in Europe, under the aegis of the EC, but also all over the world. This implies that in this new context it will be possible to access, from Spain itself, posts of growing responsibility in large post-multinational companies, and also to work in areas I have defined as more noble. The possibility of these companies implementing activities of major interest in Spain will depend on factors such as existing infrastructure, qualification of personnel and the surrounding life style. The qualification of personnel relies on basic training and promotion of research activities; therefore, these aspects will require special attention. (author)

  9. Twentieth-Century Latin American Literary Studies and Cultural Autonomy

    Directory of Open Access Journals (Sweden)

    Naomi Lindstrom


    Full Text Available Since the 1920s, when scholars first began to specialize in Latin American writing, the subject of Latin American literary studies has grown from a small subset of Spanish and Portuguese literary research and teaching to become the largest field within Hispanism and a significant presence in comparative literature. The expansion of their place in the academic world has often prompted students of Latin American literature to wonder whether, in being swept into the mainstream, their field has not left out of account the historical situations of Latin American nations. These reflections lead critics back to a problem that has troubled Latin American thinkers since Independence: the achievement, or erosion, of cultural autonomy. Though undeniably close to major powers, the Latin American nations are unequal partners in trade and cultural exchange. Corresponding to their uneven and shifting relations with Europe and later the United States, their cultural life evolves following a distinctive historical dynamic. This article considers recent efforts by scholars and essayists to characterize the features that distinguish Latin America from more politically and economically advantaged nations. Special attention goes to those scholars who, drawing on anthropological research, examine communicative and expressive practices of indigenous origin, and those who borrow from economic theory to view Latin America as shaped by its history of dependence on more powerful nations and regions.

  15. Italian neuropsychology in the second half of the twentieth century. (United States)

    Vallar, Giuseppe; Boller, François; Grossi, Dario; Gainotti, Guido


    Since the early 1960s, human neuropsychology, the study of brain-behavior interrelations, mainly based on the analysis of their pathological variations, brought about by brain damage, has had a remarkable systematical development in Italy. All this started in Milan, with the neurologist Ennio de Renzi, and his collaborators (Luigi Vignolo, then Anna Basso, Pietro Faglioni, Hans Spinnler, François Boller, and, more autonomously, Edoardo Bisiach), in the Clinic of Nervous and Mental Diseases. Scientists of the "Milan group" investigated several neuropsychological deficits caused by focal hemispheric lesions in large series of left- and right-brain-damaged patients, and control participants, comparable for cultural and demographic variables. Standardized tests and advanced statistical methods were used, which also applied to the diagnosis and rehabilitation of aphasia. Subsequently, neuropsychology developed in Italy extensively, reaching high international reputation. Leading neuropsychologists have been the neurologists Guido Gainotti (Rome), and Franco Denes (Padua), the physicians and psychologists Luigi Pizzamiglio (Rome), and Carlo Umiltà (Parma, with fruitful interactions with the neurophysiologists Giovanni Berlucchi, Giacomo Rizzolatti, and Carlo Marzi, from the school of Giuseppe Moruzzi in Pisa) A second scientific generation of neuropsychologists has then developed in the 1970s, trained by the abovementioned scientists, further boosting and spreading high-level basic and applied research (diagnosis and rehabilitation of neuropsychological deficits of patients with brain damage or dysfunction throughout the life span, from childhood to the elderly). Available techniques include structural and functional imaging (CT, PET, SPET, MRI and fMRI Scans, DTI), electrophysiological recording (EEG, ERPs), non-invasive brain stimulation (TMS, tES), and their combined use.

    Full Text Available This article analyzes the relationship between the foundation, consolidation and reinvention of the political elite in the People's Republic of China and the search to modernization from an historical perspective. To do this, this article proposes that modernity is a political project that has been an important ideological justification. This justification allowed that Chinese Communist Party took the political power. Also, the project of modernization has favored the reinvention of the political elite. The contribution of this paper is to present this process and the particular characteristics of Chinese history. In conclusion, this paper suggests that the search to modernization has been a constitutive element with deep historical roots.

    V. M. Skyrtach


    Full Text Available The purpose is to identify common and distinctive features of concepts and methodology of the problem of subject within different discourses, implicitly or explicitly relevant to the definition of "clinical" mode of human existence. The research methodology combines techniques of discourse analysis and basic principles of historical and philosophical studies. Originality of the research lies in definition of the clinical philosophical discourse as a special communicative process, where utterances not only focus on disease syndromes, and reveal phenomenology of inner experience of a pathological self, but also structure a certain type of sociality. Clinical discourse represents the space where the patient is treated not as a subject but as an object of disease. Ontology of clinical discourse prevails over ontology of disease, since its structures determine the notion of disease as such. Categorization of the disease, the idea of disease as a phenomenon subdued to professional authority leads to the idea of the need for patient’s isolation from the natural environment and removing him to special social institutions. The clinicist doctrines share the intention to reduce the patient’s self to its bodily dimension, while ignoring social determinants of psychological deviations. Conclusions of the study are summarized in the following positions: the current clinical discourse is based on the positivist-biological trend in humanitarian knowledge and it is the basis for the production and reproduction of medical and pharmaceutical repressive ideology; criticism of philosophical clinical discourse opens the possibility of overcoming the dominance of purely clinicist discourse; such a transformation is possible only after a paradigm shift in understanding the category of subject.

  6. Ethno-Demographic Processes in the North-East Black Sea Area in the 19th – Early 21th Centuries (through the Example of Greater Sochi

    Directory of Open Access Journals (Sweden)

    Aleksandr A. Cherkasov


    Full Text Available This article examines ethno-demographic processes in the north-east Black Sea area, more specifically the territory of Greater Sochi, in the 19th – early 21th centuries. In writing the article, the authors have relied on archive materials from the archives department of the administration of the city of Novorossiysk and the archives department of the administration of the city of Sochi. The authors have consulted reference pre-revolution literature, Soviet-era and present-day population censuses, as well as the findings of present-day research studies. The methodological basis of this study are the principles of historicism, objectivity, and systemicity, which helps to get an insight into the general patterns and regional peculiarities in the demographic development of the major ethnicities in the north-east Black Sea area in the 19th-20th centuries. The authors touch upon the process of colonization of the territory and its ethnic composition. In the end, the authors come to the conclusion that the ethno-demographic picture of Greater Sochi had been forming in a complicated fashion. As a consequence, in the second half of the 19th century, following the Caucasian War, the territory had to be repopulated. Resettlement flows from different locations in the Russian Empire and overseas had formed by 1917 an ethno-picture that featured Russians and Armenians as two principal ethnicities. The authors note that this picture has not changed in a major way to this day.

    Full Text Available In the first years of the Spanish Restoration, some republican feminists, together with other more moderate feminist groups, made use of the press to demand access for women to education (including higher education that would enable them to work in the liberal professions. In a later period, during the nineteenth and twentieth centuries, lay feminist networks also demanded education and freedom of conscience for women, gained access to public platforms and promoted their social actions through the network of associations linked to free thought and republicanism. Subsequently, these lay groups would adopt clearly suffragist positions alongside other feminist organisations whose main objective around 1918 was the claim for political rights. Accordingly, the fight for the emancipation of women propagated new meanings relating to womanhood that in practice led to forms of female identity that were closer to those of men. | Durante los primeros años de la Restauración, algunas feministas republicanas en conjunción con otros sectores feministas más moderados demandaron, a través de la prensa, el acceso de las mujeres a una educación, también superior, que les permitiera ejercer profesiones liberales. En una etapa posterior, las redes del feminismo laicista, entre los siglos XIX y XX, reivindicaron también la educación y la libertad de conciencia de las mujeres, accedieron a las tribunas y promovieron su acción social a través del entramado asociativo vinculado al librepensamiento y al republicanismo. Posteriormente, esos mismos núcleos laicistas evolucionarían hacia postulados claramente sufragistas en alianza con otras organizaciones feministas que, en torno a 1918, hicieron de la reivindicación de derechos políticos su principal objetivo. En todo caso, las demandas en pro de la emancipación difundieron nuevos significados en torno a las mujeres que se concretaron en la práctica en formas de identidad femenina más equivalentes a las

  9. Projected sea level rise and changes in extreme storm surge and wave events during the 21st century in the region of Singapore (United States)

    Cannaby, Heather; Palmer, Matthew D.; Howard, Tom; Bricheno, Lucy; Calvert, Daley; Krijnen, Justin; Wood, Richard; Tinker, Jonathan; Bunney, Chris; Harle, James; Saulter, Andrew; O'Neill, Clare; Bellingham, Clare; Lowe, Jason


    Singapore is an island state with considerable population, industries, commerce and transport located in coastal areas at elevations less than 2 m making it vulnerable to sea level rise. Mitigation against future inundation events requires a quantitative assessment of risk. To address this need, regional projections of changes in (i) long-term mean sea level and (ii) the frequency of extreme storm surge and wave events have been combined to explore potential changes to coastal flood risk over the 21st century. Local changes in time-mean sea level were evaluated using the process-based climate model data and methods presented in the United Nations Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5). Regional surge and wave solutions extending from 1980 to 2100 were generated using ˜ 12 km resolution surge (Nucleus for European Modelling of the Ocean - NEMO) and wave (WaveWatchIII) models. Ocean simulations were forced by output from a selection of four downscaled ( ˜ 12 km resolution) atmospheric models, forced at the lateral boundaries by global climate model simulations generated for the IPCC AR5. Long-term trends in skew surge and significant wave height were then assessed using a generalised extreme value model, fit to the largest modelled events each year. An additional atmospheric solution downscaled from the ERA-Interim global reanalysis was used to force historical ocean model simulations extending from 1980 to 2010, enabling a quantitative assessment of model skill. Simulated historical sea-surface height and significant wave height time series were compared to tide gauge data and satellite altimetry data, respectively. Central estimates of the long-term mean sea level rise at Singapore by 2100 were projected to be 0.52 m (0.74 m) under the Representative Concentration Pathway (RCP)4.5 (8.5) scenarios. Trends in surge and significant wave height 2-year return levels were found to be statistically insignificant and/or physically

  11. The ecological century

    Energy Technology Data Exchange (ETDEWEB)

    Worthington, E. B.


    This essay attempts to reconstruct the evolution of Ecology as the scientific basis for environmental conservation and human progress, as seen through the eyes of a biologist who has exercised that science during a number of tasks in various parts of the world over most of the twentieth century. From its beginnings in evolutionary thinking during the nineteenth century, ecology emerged from natural history at the beginning of the twentieth. At first the running was made by botanists; but this was soon followed by zoologists, who dealt with more mobile communities. The first quarter-century was mainly exploratory; the second was mainly descriptive (although biological exploration was still dominant in the tropics). The third quarter saw ecology developing into an experimental science, and, as the environmental revolution got into its stride, ecology became organized both nationally and internationally. Although the term is now often misused and sometimes misunderstood by laymen, the last quarter-century is seeing the wide application of ecology in environmental and human affairs, and this gives some assurance that the twenty-first century will not become one of chaos.

  12. Coastal fisheries in the Eastern Baltic Sea (Gulf of Finland and its basin from the 15 to the Early 20th centuries.

    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.

  17. The sea ice mass budget of the Arctic and its future change as simulated by coupled climate models

    Arctic sea ice mass budgets for the twentieth century and projected changes through the twenty-first century are assessed from 14 coupled global climate models. Large inter-model scatter in contemporary mass budgets is strongly related to variations in absorbed solar radiation, due in large part to differences in the surface albedo simulation. Over the twenty-first century, all models simulate a decrease in ice volume resulting from increased annual net melt (melt minus growth), partially compensated by reduced transport to lower latitudes. Despite this general agreement, the models vary considerably regarding the magnitude of ice volume loss and the relative roles of changing melt and growth in driving it. Projected changes in sea ice mass budgets depend in part on the initial (mid twentieth century) ice conditions; models with thicker initial ice generally exhibit larger volume losses. Pointing to the importance of evolving surface albedo and cloud properties, inter-model scatter in changing net ice melt is significantly related to changes in downwelling longwave and absorbed shortwave radiation. These factors, along with the simulated mean and spatial distribution of ice thickness, contribute to a large inter-model scatter in the projected onset of seasonally ice-free conditions. (orig.)

  19. Northern Alaskan land surface response to reduced Arctic sea ice extent

[University of Colorado, Cooperative Institute for Research in Environmental Sciences, Department of Atmospheric and Oceanic Sciences, Boulder, CO (United States)


    With Arctic sea ice extent at near-record lows, an improved understanding of the relationship between sea ice and the land surface is warranted. We examine the land surface response to changing sea ice by first conducting a simulation using the Community Atmospheric Model version 3.1 with end of the twenty-first century sea ice extent. This future atmospheric response is then used to force the Weather and Research Forecasting Model version 3.1 to examine the terrestrial land surface response at high resolution over the North Slope of Alaska. Similar control simulations with twentieth century sea ice projections are also performed, and in both simulations only sea ice extent is altered. In the future sea ice extent experiment, atmospheric temperature increases significantly due to increases in latent and sensible heat flux, particularly in the winter season. Precipitation and snow pack increase significantly, and the increased snow pack contributes to warmer soil temperatures for most seasons by insulating the land surface. In the summer, however, soil temperatures are reduced due to increased albedo. Despite warmer near-surface atmospheric temperatures, it is found that spring melt is delayed throughout much of the North Slope due to the increased snow pack, and the growing season length is shortened.

  20. Reassessing biases and other uncertainties in sea surface temperature observations measured in situ since 1850: 2. Biases and homogenization (United States)

    Kennedy, J. J.; Rayner, N. A.; Smith, R. O.; Parker, D. E.; Saunby, M.


    Changes in instrumentation and data availability have caused time-varying biases in estimates of global and regional average sea surface temperature. The size of the biases arising from these changes are estimated and their uncertainties evaluated. The estimated biases and their associated uncertainties are largest during the period immediately following the Second World War, reflecting the rapid and incompletely documented changes in shipping and data availability at the time. Adjustments have been applied to reduce these effects in gridded data sets of sea surface temperature and the results are presented as a set of interchangeable realizations. Uncertainties of estimated trends in global and regional average sea surface temperature due to bias adjustments since the Second World War are found to be larger than uncertainties arising from the choice of analysis technique, indicating that this is an important source of uncertainty in analyses of historical sea surface temperatures. Despite this, trends over the twentieth century remain qualitatively consistent.

  1. Quantification of the early small-scale fishery in the north-eastern Baltic Sea in the late 17th century. (United States)

    Verliin, Aare; Ojaveer, Henn; Kaju, Katre; Tammiksaar, Erki


    Historical perspectives on fisheries and related human behaviour provide valuable information on fishery resources and their exploitation, helping to more appropriately set management targets and determine relevant reference levels. In this study we analyse historical fisheries and fish trade at the north-eastern Baltic Sea coast in the late 17th century. Local consumption and export together amounted to the annual removal of about 200 tonnes of fish from the nearby sea and freshwater bodies. The fishery was very diverse and exploited altogether one cyclostome and 17 fish species with over 90% of the catch being consumed locally. The exported fish consisted almost entirely of high-valued species with Stockholm (Sweden) being the most important export destination. Due to rich political history and natural features of the region, we suggest that the documented evidence of this small-scale fishery should be considered as the first quantitative summary of exploitation of aquatic living resources in the region and can provide a background for future analyses.

    Full Text Available The article discusses the activities of the armenian parties Dashnaktsutyun and Gnchak on the territory of the Black sea province at the beginning of the XX century. The article is paid attention to the reasons of participation of armenians in the revolutionary events of 1905–1907. The authors have selected as materials the archival documents of the central and regional archives, namely the state archive of Russian Federation, the Russian State Archive of Social and Political History, the state archive of the Krasnodar Krai, a documentation center of the modern history of the Krasnodar Krai, the archive department ofSochi city and the museum of Sochi history. The authors come to the conclusion thatdespite the existing problems in relations with the armenian population of the Black sea province until 1905, the armenians are forced to participate in the riots of the First russian Revolution. Later, during the investigation of the Sochi republic that has been established, and the Armenian population avoidedthe criminal liability.

  4. Stable Isotopes of Nitrogen in Fossil Cladoceran Exoskeletons: Implications for Nitrogen Sources in the Central Baltic Sea During the Past Century (United States)

    Struck, Ulrich; Voss, Maren; von Bodungen, Bodo; Mumm, Nicolai

    The ratios of stable nitrogen isotopes were analysed in zooplankton exoskeletons extracted from dated sediment cores from the Gotland Basin of the central Baltic Sea. Combined with results on δ15N of bulk sediment, organic carbon concentrations, and abundances of exoskeletons of Bosminalongispinamaritima in the sediment, the data are used to evaluate significant sources of nitrogen in the food web over the past century. Nitrogen isotopic composition of bulk sediments ranges from 2.5 to 4.5ö, that of exokeletons varies between 0.4 and 6.2ö. The two are positively correlated. A marked increase in the abundance of Bosmina since 1965 (from less than 500 specimen to more than 5000 specimencm3 of sediment) is correlated with a significant increase in sedimentary organic carbon concentrations (from 4% to more than 10%). The isotopic data do not identify increased land-derived nitrate as the dominant nitrogen source fuelling the increase. Instead, we postulate that nitrogen fixation by diazotrophic bacteria has been one of the larger sources of nitrogen in the Baltic Sea, as it is today.

    This study examines the potential impact of 21st century sea-level rise on Aarhus, the second largest city in Denmark, emphasizing the economic risk to the city's real estate. Furthermore, it assesses which possible adaptation measures that can be taken to prevent flooding in areas particularly at risk from flooding. We combine a new national Digital Elevation Model in very fine resolution (∼2 meter), a new highly computationally efficient flooding algorithm that accurately models the influence of barriers, and geospatial data on real-estate values to assess the economic real-estate risk posed by future sea-level rise to Aarhus. Under the A2 and A1FI (IPCC) climate scenarios we show that relatively large residential areas in the northern part of the city as well as areas around the river running through the city are likely to become flooded in the event of extreme, but realistic weather events. In addition, most of the large Aarhus harbour would also risk flooding. As much of the area at risk represent high-value real estate, it seems clear that proactive measures other than simple abandonment should be taken in order to avoid heavy economic losses. Among the different possibilities for dealing with an increased sea level, the strategic placement of flood-gates at key potential water-inflow routes and the construction or elevation of existing dikes seems to be the most convenient, most socially acceptable, and maybe also the cheapest solution. Finally, we suggest that high-detail flooding models similar to those produced in this study will become an important tool for a climate-change-integrated planning of future city development as well as for the development of evacuation plans.

    Full Text Available Aim of this paper is to investigate the traditional technologies of lifting and sea transport of large stone blocks (time spent for sea transport, ways of charging and stewing large stone pieces, number of people engaged with evidence from 18th and 19th century Italy, as a key to understand ancient Roman practices. I shall use data from reconstruction of the 5th century Christian basilica of St. Paul at Rome, burnt in 1823, where new granite shafts, mainly from Italian quarries, replaced the Roman ones. Other documentary sources help to understand some details related to heavy transport, otherwise unknown for Roman period. It should be obviously dangerous to induce directly that the same technologies used for lifting and transport of columns in 18th or 19th century were in use also in Roman Imperial age, but the study of such processes can help us to put in the right view our reconstruction of ancient reality.

The NACO instrument has obtained amazing images of the rings, while SINFONI has been used to study the changes in the rings' appearances and the evolution of the spectral lines. "SN 1987A was full of surprises and it remains unique amongst the known supernovae," says Leibundgut. "Not only was it the closest supernova for several centuries, it was also very peculiar, coming from a blue supergiant progenitor, with a circumstellar environment unlike any other supernova known. We will certainly continue to monitor its evolution for many years to come." One goal will be to find the possible compact object that should have survived the dramatic explosion. But until now, this remnant has proved elusive

  13. Potential Predictability of the Sea-Surface Temperature Forced Equatorial East Africa Short Rains Interannual Variability in the 20th Century (United States)

    Bahaga, T. K.; Gizaw, G.; Kucharski, F.; Diro, G. T.


    In this article, the predictability of the 20th century sea-surface temperature (SST) forced East African short rains variability is analyzed using observational data and ensembles of long atmospheric general circulation model (AGCM) simulations. To our knowledge, such an analysis for the whole 20th century using a series of AGCM ensemble simulations is carried out here for the first time. The physical mechanisms that govern the influence of SST on East African short rains in the model are also investigated. It is found that there is substantial skill in reproducing the East African short rains variability, given that the SSTs are known. Consistent with previous recent studies, it is found that the Indian Ocean and in particular the western pole of the Indian Ocean dipole (IOD) play a dominant role for the prediction skill, whereas SSTs outside the Indian Ocean play a minor role. The physical mechanism for the influence of the western Indian Ocean on East African rainfall in the model is consistent with previous findings and consists of a gill-type response to a warm (cold) anomaly that induces a westerly(easterly) low-level flow anomaly over equatorial Africa and leads to moisture flux convergence (divergence) over East Africa. On the other hand, a positive El Nino-Southern Oscillation (ENSO) anomaly leads to a spatially non-coherent reducing effect over parts of East Africa, but the relationship is not strong enough to provide any predictive skill in our model. The East African short rains prediction skill is also analyzed within a model-derived potential predictability framework and it is shown that the actual prediction skill is broadly consistent with the model potential prediction skill. Low-frequency variations of the prediction skill are mostly related to SSTs outside the Indian Ocean region and are likely due to an increased interference of ENSO with the Indian Ocean influence on East African short rains after the mid-1970s climate shift.

  15. Accelerated contributions of Canada's Baffin and Bylot Island glaciers to sea level rise over the past half century

    Directory of Open Access Journals (Sweden)

    A. Gardner


    Full Text Available Canadian Arctic glaciers have recently contributed large volumes of meltwater to the world's oceans. To place recently observed glacier wastage into a historical perspective and to determine the region's longer-term (~50 years contribution to sea level, we estimate mass and volume changes for the glaciers of Baffin and Bylot Islands using digital elevation models generated from airborne and satellite stereoscopic imagery and elevation postings from repeat airborne and satellite laser altimetry. In addition, we update existing glacier mass change records from GRACE satellite gravimetry to cover the period from 2003 to 2011. Using this integrated approach, we find that the rate of mass loss from the region's glaciers increased from 11.1 ± 3.4 Gt a−1 (271 ± 84 kg m−2 a−1 for the period 1963–2006 to 23.8 ± 6.1 Gt a−1 (581 ± 149 kg m−2 a−1 for the period 2003–2011. The doubling of the rate of mass loss is attributed to higher temperatures in summer with little change in annual precipitation. Through both direct and indirect effects, changes in summer temperatures accounted for 70–98% of the variance in the rate of mass loss, to which the Barnes Ice Cap was found to be 1.7 times more sensitive than either the Penny Ice Cap or the region's glaciers as a whole. This heightened sensitivity is the result of a glacier hypsometry that is skewed to lower elevations, which are shown to have a higher mass change sensitive to temperature compared to glacier surfaces at higher elevations. Between 2003 and 2011 the glaciers of Baffin and Bylot Islands contributed 0.07 ± 0.02 mm a−1 to sea level rise accounting for 16% of the total contribution from glaciers outside of Greenland and Antarctica, a rate much higher than the longer-term average of 0.03 ± 0.01 mm a−1 (1963 to 2006.

  16. Commodity Price Fluctuations: A Century of Analysis


    Walter Labys


    Commodity prices again! The twentieth century has only been the latest spectator to the impacts and importance of commodity price fluctuations. It is reasonably well known that commodity price records have come down to us from the ancient civilizations of India, Mesopotamia, Egypt, Greece and Rome. Earlier in the century, formal research began on the relationships between agricultural demand, supply and prices in a market context. This research not only evolved in sophistication but extended ...

  17. Women’s Costume of German Origin in the Funeral Context of Early Byzantine Cities of the Northern Black Sea (5th–6th Centuries

    Directory of Open Access Journals (Sweden)

    Anna V. Mastykova


    Full Text Available This work is devoted to burials containing elements of a female costume of East German origin, discovered in the urban necropolises of Chersonesus and Cimmerian Bosporus in the 5th–6th centuries. Burials with German objects are most often in the same collective tombs and in the same necropolises as the burial of the urban Hellenized population. The appearance and resettlement of the eastern Germans in the cities of the Northern Black Sea Coast is attested by written sources only for the Cimmerian Bosporus. About 400 Goths could even occupy a dominant position here. This explains their integration into the Bosporus ruling elite, as evidenced by the existence of rich graves with German implements in the tombs of the local nobility. Later, Cimmerian Bosporus is under the rule of the Huns, and in 534 the military expedition sent by Justinian returns the region to the power of the Empire. Written sources directly indicate the presence of Gothic federates from Minor Scythia as part of the Justinian assault. Therefore, the researchers explain the appearance of a new series of East German things in the Northern Black Sea region by the arrival here of the German soldiers with their families. On the other hand, the violent deportation of barbarians to the Crimea is also possible – a practice well known in the Justinian era. This is how you can explain the appearance here of Italo-Ostrogothic and Gepidic things. In Chersonese German things could fall and as a result of various contacts with the Goths from the country of Dori, in the South-Western Crimea. However, despite the various historical destinies and different statutes of the Germans, in the north-Pontic cities they sooner or later come to be absorbed by the local environment, which reflects the finds of the items of female clothing in urban necropolises.

    The Chinese migration to Mazatlan and Mexico, began in the mid-nineteenth century, via San Francisco. They were the most important foreign colony from the early decades of the twentieth century. On arrival the Chinese population lacked capital as largely devoted to provide their services as domestic workers, especially farmers and craft activities related to repairing and making shoes. With the advent of the twentieth century and the accumulation of some capital, began its foray into the reta...

  2. A heuristic evaluation of long-term global sea level acceleration (United States)

    Spada, Giorgio; Olivieri, Marco; Galassi, Gaia


    In view of the scientific and social implications, the global mean sea level rise (GMSLR) and its possible causes and future trend have been a challenge for so long. For the twentieth century, reconstructions generally indicate a rate of GMSLR in the range of 1.5 to 2.0 mm yr-1. However, the existence of nonlinear trends is still debated, and current estimates of the secular acceleration are subject to ample uncertainties. Here we use various GMSLR estimates published on scholarly journals since the 1940s for a heuristic assessment of global sea level acceleration. The approach, alternative to sea level reconstructions, is based on simple statistical methods and exploits the principles of meta-analysis. Our results point to a global sea level acceleration of 0.54 ± 0.27 mm/yr/century (1σ) between 1898 and 1975. This supports independent estimates and suggests that a sea level acceleration since the early 1900s is more likely than currently believed.

  5. Twenty-first century vaccines (United States)

    Rappuoli, Rino


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

  6. Sources, variability and fate of freshwater in the Bellingshausen Sea, Antarctica (United States)

    Regan, Heather C.; Holland, Paul R.; Meredith, Michael P.; Pike, Jennifer


    During the second half of the twentieth century, the Antarctic Peninsula was subjected to a rapid increase in air temperatures. This was accompanied by a reduction in sea ice extent, increased precipitation and a dramatic retreat of glaciers associated with an increase in heat flux from deep ocean water masses. Isotopic tracers have been used previously to investigate the relative importance of the different freshwater sources to the adjacent Bellingshausen Sea (BS), but the data coverage is strongly biased toward summer. Here we use a regional model to investigate the ocean's response to the observed changes in its different freshwater inputs (sea ice melt/freeze, precipitation, evaporation, iceberg/glacier melt, and ice shelf melt). The model successfully recreates BS water masses and performs well against available freshwater data. By tracing the sources and pathways of the individual components of the freshwater budget, we find that sea ice dominates seasonal changes in the total freshwater content and flux, but all sources make a comparable contribution to the annual-mean. Interannual variability is dominated by sea ice and precipitation. Decadal trends in the salinity and stratification of the ocean are investigated, and a 20-year surface freshening from 1992 to 2011 is found to be predominantly driven by decreasing autumn sea ice growth. These findings will help to elucidate the role of freshwater in driving circulation and water column structure changes in this climatically-sensitive region.

    A high-resolution integrated study, which includes tephrochronology (tefra layer associated to 1906 AD Vesuvius event) and radionuclide dating method (210Pb and 137Cs), has been performed in a super-expanded marine record (sedimentation rate of 0.47 cm/yr) from the continental shelf of the Gulf of Gaeta (central eastern Tyrrhenian Sea). Planktonic foraminifera, calcareous nannofossils, pollens and oxygen stable isotope data performed on Globigerinoides ruber, revealed environmental changes occurred during the last two centuries. In detail we recognise four paleoclimatic changes. From ca. 1800 to ca. 1865 AD, d18O G. ruber signal combined with evidences of abundance increase of planktonic foraminifera Globoratialia inflata and G. truncatulinoides and of calcareous nannofossils Emiliana huxley document cold-temperate phase. Between ca. 1865 and ca. 1882 AD, d18O G. ruber record document a short warm interval associated with a turnover from carnivorous to herbivorous-opportunistic planktonic foraminiferal species and an increase in abundance of calcareous nannofossil Florisphaera profunda. At ca. 1935 AD, d18O G. ruber data indicate a gradually warming, concomitant an evident turnover from carnivorous to herbivorous-opportunistic planktonic foraminiferal species, and associated to the increase of calcareous nannofossil F. profunda. From ca. 1950 AD to the present day the warm phase documents a further strong increase in G. ruber alba, G. quadrilobatus and F. profunda abundances. The pollen analysis carried out on the same core revealed a two-step increase in arboreal vegetation, this is mostly related to a rise of Olea, Quercus evergreen and riparian trees (Alnus and Salix) from ca. 1882 AD, and increase in conifers (Pinus and Cupressaceae) from ca. 1980 AD. The short lived warm interval documented by d18O between ca. 1865 and ca. 1882 AD may triggered the increase in Olea and the coeval general decrease in deciduous trees. Among herbs, Cyperaceae, along with ferns

    ão .This article analyzes the institutional transformation of the Provincial Police of Buenos Aires during the first half of the Twentieth Century. First, the period from the 1880s when both city and provincial police were separated up to the 1920s is studied. Then, the institutional evolution of this Law Enforcement Agency is divided in three stages: 1 the 1930s when significant changes began to taking place, 2 the military coup of 1943 and the following Peronist period, when a deep administrative police reform happened. And 3 the years of the Revolución Libertadora from 1955 on, analyzed in this article as a conclusion. The entire piece refers to the transition from a brava (1930s to a dura (1960s police agency that issued its own institutional goals in concurrence with the political and military governments during those decades.

  10. Tree ring-based seven-century drought records for the Western Himalaya, India (United States)

    Yadav, Ram R.


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

  12. Climate: Into the 21st Century (United States)

    Burroughs, William


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

    This paper traces the ancestry of a familiar historiographical narrative, according to which early modern philosophy was marked by the development of empiricism, rationalism, and their synthesis by Immanuel Kant. It is often claimed that this narrative became standard in the nineteenth century, due to the influence of Thomas Reid, Kant and his disciples, or German Hegelians and British Idealists. The paper argues that the narrative became standard only at the turn of the twentieth century. Th...

In the span of 100 years, completed years of schooling doubled and working hours decreased by 30 percent. What explains these trends? We consider a model of human capital and labor supply t...

  20. Causes of accelerating sea level on the East Coast of North America. (United States)

    Davis, James L; Vinogradova, Nadya T


    The tide-gauge record from the North American East Coast reveals significant accelerations in sea level starting in the late twentieth century. The estimated post-1990 accelerations range from near zero to ∼0.3 mm yr -2 . We find that the observed sea level acceleration is well modeled using several processes: mass change in Greenland and Antarctica as measured by the Gravity Recovery and Climate Experiment satellites; ocean dynamic and steric variability provided by the GECCO2 ocean synthesis; and the inverted barometer effect. However, to achieve this fit requires estimation of an admittance for the dynamical and steric contribution, possibly due to the coarse resolution of this analysis or to simplifications associated with parameterization of bottom friction in the shallow coastal areas. The acceleration from ice loss alone is equivalent to a regional sea level rise in one century of 0.2 m in the north and 0.75 m in the south of this region.

  1. Benthic community structures in the North Sea (United States)

    Heip, C.; Craeymeersch, J. A.


    Coherent assemblages of marine benthic species have been recognized from the early twentieth century, and the classical papers of Petersen (1914, 1918) were based on studies of limited areas in the North Sea. In 1986, a synoptic survey of the North Sea north to 57°N was undertaken by a group of ten laboratories from seven North Sea countries. The results of this survey have recently been published (Heip et al., 1992a, b; Künitzer et al., 1992; Huys et al., 1992), and some of the results are summarized in this paper. The analysis of the macrofauna is based on slightly more than 700 taxa. In general, the North Sea macrofauna consists of northern species extending south to the northern margins of the Dogger Bank, and southern species extending north to the 100 m depth line. The central North Sea is an area of overlap of southern and northern species, especially around the 70 m depth contour. Consistent groupings of species are recognized that were summarized in seven faunal groupings. Macrofaunal body weight, density and diversity increase linearly towards the north. Macrofaunal biomass for the whole area averages 7 g adwt. m-2 and decreases from south to north. Distribution patterns and trends within the meiofauna were very different. Nematodes, which are the dominant taxon overall, are least abundant in the sandy sediments of the Southern Bight, then increase to a maximum around 53° 30' N and slowly decrease again towards the north. Copepod density and diversity are highest in the Southern Bight, due to the presence of many interstitial species. A large number of species new to science were recorded by the North Sea Benthos Survey and about 1500 species are expected to occur. Copepods show very distinct assemblages according to water depth and sediment type. The contrasting patterns in latitudinal gradients of body weight and number of species of macro- and meiofauna can be only partially explained. Latitude and sediment characteristics, such as grain size and
