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

  2. Norm of Exploitation of Miners in Siberia in the Late 19th – Early 20th Centuries

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

    In the early 20th century, some American ministers were eager participants in the Chautauqua and Lyceum lecture circuits that flourished across the Midwest and beyond. Ministers expressed their vocation in the public arena, and the Redpath Chautauqua collection shows how part of this public life was conducted. In their role as lecturers in multiple educational and civic venues, ministers functioned as experts on the Bible, as well as supporting American ideals that were loosely connected to P...

    Elementary schooling in North America in the early 20th century underwent major changes with the spread of graded schools with multiple classrooms and teachers to semi-urban and rural areas. Detailed schooling records from British Columbia indicate that pupil attendance responded strongly to the introduction of additional teachers in one-room schools. The attendance impact of grading a school dominated alternatives such as employing more highly qualified teachers, or building additional schoo...

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

    Full Text Available There are many monographs, articles, chapters and exhibitions and their catalogues dedicated to Croatian posters from the early 20th century. Posters are evaluated as works of art, but received very little attention as an advertising medium. Their communication and advertising role in the specified time and place has not been investigated thoroughly. This paper does not investigate the relationship between the artistic and marketoriented aspects of posters, neither does it evaluate which and what type of posters deserve to be considered works of art. It focuses on how and where did people in the early 20th century used posters to inform themselves about new events and products. Posters are viewed only as a communicative and promotion medium, and the place where they were displayed as a sort of an information hub.The authors investigate the possibility of using two types of historical resources: city administration documents that regulated the displaying of posters and different pictures - like postcards, newspaper photos showing current events, posters and notice-boards or columns. The city of Osijek is selected as a case study for this approach. As the appropriation of posters is determined by their content, graphic design and place where they are displayed, the aim of the paper is to investigate the possible resources that can help us reconstruct the procedures and locations for poster displays. Following the methodology proposed by Robert Darnton, who listed five possible approaches to investigating different texts, and by Roger Chartier’s papers in which he stresses the importance of content appropriation, i.e. the subjectivity of readers, and not the de-contextualized content itself, the authors propose a step from posters to displaying them - or advertising - in public places in the city.Analyzing the above stated sources it can be established that there was a demand for the public advertising space in Osijek in the early 20th century. Advertising columns were covered in posters and served as ‘information centers’. It can be concluded that the efficiency of posters depended on their graphic design and the way they were displayed in the public space in the city, as most posters, especially the ones on cultural issues, did not rely as much on visual attractiveness or quick transfer of information, as they did on the continuity of the location where they were displayed. There was a huge demand for the advertising space, as the city administration had to draft statutes to regulate the displaying of posters. There were clients who rented the display rights for a certain time period. It can be concluded that there were many businesses and institutions that wanted or had to advertise their products, services or events, as well as the interested citizens who needed this information.The authors believe that the investigation of the communicative role of posters cannot rely only on the evaluation of the different aspects of posters themselves, but they had to be observed as communication media. The display or publishing mode also needs to be taken into consideration. Therefore, posters must be contextualized and analyzed in the public city space where they were displayed. Two historical resources that we used in this paper: city administration ordinances and visual records (postcards and photos, can be used as very useful to reconstruct the procedure and place for displaying posters. Key words : poster, poster displays, promotion, media, communication, Osijek, advertising columns, poster appropriation.

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

    CERN Document Server

    Martini, José X

    2007-01-01

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

  7. ANTHROPOLOGICAL PROBLEMS IN THE PHILOSOPHICAL WORKS OF RUSSIAN SPIRITUAL ACADEMIES’ TEACHERS OF THE EARLY 20TH CENTURY

    Full Text Available The paper deals with the analysis of philosophical and theological creativity of Russian theological academies’ teachers of the early 20th century. The aim of this study is to identify the impact of methodological foundations’ changes of philosophical-theological quest on the teachers of Russian theological academies and the educational process itself in theological schools. Methods. The author focuses on the content of training courses delivered in the theological academies in the first two decades of the 20th century; problem statement peculiarities; aspect and priority choice in the fundamental researches conducted by the teachers of these schools. The applied methods include the comparative method, analysis, synthesis, method of abstraction, other philosophical and scientific methods. Results. The author comes to the conclusion that the changes of methodological installations in scientific research representatives of spiritual and academic theism beginning of the 20th century can be compared with similar studies of the nineteenth century. It is mentioned that reorientation of a number of prominent representatives of spiritual and academic theism from scholastic methods, speculative psychology and metaphysics towards Patristics, asceticism and personal experiences allows us to propose this movement as West-European Philosophy searches of the same period. Thus, V. I. Nesmelov sees the basis of any religious teachings in the experience of human cognition. M. M. Tareev draws up his own moral theology reading course based on the personal experience living the Gospel Book. Archimandrite Sergious (Stragorodsky interprets the topic of finding salvation not against the background of the changes in God, but from the standpoint of the changes that occur in humanity. Bishop Theodore (Pozdeevsky, Archbishop Hilarion (Troitsky and Bishop Barnabas (Belyaev make known scholasticism as epistemological malice characterizing the specifics of theological knowledge necessary to base their intellectual efforts on the personal experience of the struggle against the passions; therefore, they see the new basis of theology in asceticism. Professor S. V. Troitsky considers marriage as the key problem for religion and philosophy of the early 20th century. Professor S. S. Glagolev sees the descent of a man as the crossing point of religion and science. The author mentions that despite some heterogeneity of the proposed concepts, there is an obvious General anthropological orientation that had an impact on the educational process changes in theological academies (seminaries. Scientific novelty. The author systemizes and sums up anthropologic views of the most recognizable ecclesiastical academics in the early 20th century. Representation and analysis of anthropologic problematics in philosophical and religious papers of the Russian ecclesiastical education stage of development signify essential agreement among Russian and Western sophists; they had been discussing the same problem – a human being. The author points out that their discussions were not absolutely the same, but it gives the reason to regard the anthropology of the early 20th century as modern Philosophy; and this difference allows academic anthropology to avoid classic and non-classic types of philosophy. Practical significance. The research outcomes can be used for further understanding development of the all European searching process of the early 20th century. Received by the author of the study findings provide its scientific innovation. The results of this study can be used in assessing the role of theological academies in European cultural processes and culture of the Russian society of the early 20th century; research findings can enrich the content of the lectures on the History of Philosophy, Russian History, European History, Cultural Studies and other Humanities (non-science disciplines.

    Children's fiction in school libraries have played and still play a role in mediating representations of technology and attitudes towards technology to schoolchildren. In early 20th century Sweden, elementary education, including textbooks and literature that were used in teaching, accounted for the main mediation of technological knowledge to schoolchildren. An investigation of children's literature for schools is therefore important in order to understand what was considered worth knowing a...

    2013-12-01

    Roald Amundsen (1872-1928) is best known as a polar explorer, the first to lead a team to the South Pole in 1911. He did, however, have a serious interest in science, in particular, in geomagnetism. His expedition through the Northwest Passage above Canada in 1903 to 1906 and his Maud expedition through the Arctic ice in 1918 to 1925 included full complements of magnetic instrumentation. He and his magnetic researchers collaborated with the Carnegie Institution of Washington's Department of Terrestrial Magnetism and with the Prussian Geomagnetic Observatory in Potsdam for training, instruments, and research programs. Amundsen's expeditions provided magnetic and other geophysical data for important geographical regions, while gaining support for polar and geophysical research generally. His work is part of a broader 20th-century story that includes the International Polar Years and the International Geophysical Year.

  12. Age-specific measles mortality during the late 19th-early 20th centuries.

    Measles mortality fell prior to the introduction of vaccines or antibiotics. By examining historical mortality reports we sought to determine how much measles mortality was due to epidemiological factors such as isolation from major population centres or increased age at time of infection. Age-specific records were available from Aberdeen; Scotland; New Zealand and the states of Australia at the end of the 19th and beginning of the 20th centuries. Despite the relative isolation of Australia, measles mortality was concentrated in very young children similar to Aberdeen. In the more isolated states of Tasmania, Western Australia and Queensland adults made up 14-15% of measles deaths as opposed to 8-9% in Victoria, South Australia and New South Wales. Mortality in Iceland and Faroe Islands during the 1846 measles epidemic was used as an example of islands isolated from respiratory pathogens. The transition from crisis mortality across all ages to deaths concentrated in young children occurred prior to the earliest age-specific mortality data collected. Factors in addition to adult age of infection and epidemiological isolation such as nutritional status and viral virulence may have contributed to measles mortality outcomes a century ago.

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

    2015-04-01

    One of the major Dutch landscapes is formed by lowland rivers. They divide the country in a southern and a northern part, both physically and culturally. We screened the freely available database of 19th and early 20th century paintings of Simonis & Buunk, www.simonis-buunk.com, looking for lowland river landscapes depicting geodiversity and cultural heritage relationships (See References for other landscapes). Emperor Napoleon declared The Netherlands as naturally belonging to his empire as its lands originated from muds originating in France and transported there by the big rivers. A description that may have given rise to the idea of the Netherlands as a delta, but from a geomorphological perspective The Netherlands consists of series of river plains of terrestrial origin, of which the north-western part are subsiding and invaded by the sea. Now, the rivers Meuse and Rhine (including its branches Waal and IJssel) meander through ever larger river plains before reaching the North Sea. They end in estuaries, something one would not expect of rivers with catchments discharging a large part of Western Europe. Apart from the geological subsidence, the estuaries might be due to human interference, the exploitation of peat and building of dikes since the 11th century, heavy storms and the strong tidal currents. Archaeological finds show Vikings and Romans already used the river Rhine system for trading and transporting goods. During the Roman Empire the Rhine was part of The Limes, the northern defence line of the empire. Romans already influenced the distribution of water over the different river branches. Since the middle of the 19th century groins and canalization drastically changed the character of the rivers. The 19th and early 20th century landscape paintings illustrate this change as well as changes in land use. Examples of geodiversity and cultural heritage relationships shown: - meanders and irregular banks disappear as river management increases, i.a. bends are straightened and the flow is regulated by groins; - large-stem orchards on the river banks are replaced by low-stem orchards; - big trees still grow on the river banks on the oldest paintings; - 19th century dikes align the river and are low compared to modern dikes; - transport of trade goods always has been an important river function; - the 19th century small-scale shipyards have disappeared from the banks; - ferry crossings remained a popular painting object, while bridges are seldom depicted - building bridges started in the mid-19th century; - commercial fishery on migrating salmon has disappeared since; - skating scenes indicate the rivers froze more often in this period.

    2014-01-01

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

    2015-01-01

    Individual stature depends on multifactorial causes and is often used as a proxy for investigating the biological standard of living. While the majority of European studies on 19th and 20th century populations are based on conscript heights, stature derived from skeletal remains are scarce. For the first time in Denmark this study makes a comparison between skeletal stature and contemporary Danish conscript heights and investigates stature of males and females temporally and between socially distinct individuals and populations in 19th and early 20th century Copenhagen. A total of 357 individuals (181 males, 176 females) excavated at the Assistens cemetery in Copenhagen is analyzed. Two stature regression formulae (Trotter, 1970; Boldsen, 1990) are applied using femur measurements and evaluated compared to conscript heights. The results indicate that mean male stature using Boldsen follows a similar trend as the Danish conscript heights and that Trotter overestimate stature by ca. 6cm over Boldsen. At an inter population level statistically significant differences in male stature are observed between first and second half of the 19th century towards a slight stature decrease and larger variation while there are no significant changes observed in female stature. There are insignificant differences in stature between middle and high class individuals, but male stature differs statistically between cemeteries (p=0.000) representing middle/high class, paupers and navy employees, respectively. Female stature had no significant wealth gradient (p=0.516). This study provides new evidence of stature among males and females during the 19th century and suggests that males may have been more sensitive to changes in environmental living and nutrition than females.

To revisit all the historic glaciers would be a near impossible, not to mention extremely expensive task, so we targeted the most important glaciers in terms of present mass loss as well as the most aesthetically appealing historical images. The result is a then-and-now comparison that vividly captures both the raw beauty of the land and the ongoing often dramatic glacial changes. As the historic flights covered nearly half the Greenlandic coast line, we capture both areas of massive retreat and areas of still stand and even advance.

  20. Conservation of 19th and early 20th century oil paintings - in situ studies using the environmental scanning electron microscope

    International Nuclear Information System (INIS)

    Full text: Most 19th and early 20th century oil paintings suffer from fading, discolouration, pitting, cracking swelling or the loss of material due to the embrittlement or the extreme friability of the paint layers. As a consequence of this deterioration, they require special care by experienced conservators to ensure their continued preservation. These aging processes are a consequence of (i) chemical interactions between pigments, oils and binders used by the artist and (ii) the action of air, water and ultra-violet irradiation on these materials. The influence of chemical interactions is pertinent for paintings of this era as the industrial revolution brought forth new colourful chemicals that were quickly adopted as pigments with varying success. The conservation of oil paintings requires an understanding of the individual structure of each work of art and what mechanisms underlie its deterioration. This generally involves the need for (i) correct identification of the pigments used by the artist, (ii) a detailed knowledge of the chemical interaction between these pigments, (iii) an understanding of the artist's method of mixing colours and laying paint on the canvas and (iv) a detailed knowledge of the role of the atmosphere, moisture and UV irradiation on painting deterioration. In addition to dealing with the deterioration that occurs within the painting, conservators spend a large portion of their time correcting earlier failed conservation attempts. Most oil paintings from this era are valuable from an artistic or historic perspective and only an extremely small sample may be excised from the work, hence microscopy is an indispensable technique in art preservation. Optical microscopy is the core analysis technique used, however, in recent years a limited number of conservators have begun to use Environmental scanning electron microscopy (ESEM) technology to examine paint layers to take advantage of the accurate and rapid identification of elements present in layers of paints it allows. X-ray diffraction (XRD) can be used to ascertain pigments based on their crystal structure but this technique is generally ruled out due to the relatively large sample required for accurate identification. In this project techniques have been developed to examine the chemical interaction of pigments in oil paintings using the ESEM. The ultimate aim is to investigate these aging and degradation processes in situ under accelerated conditions using the controlled gas phase and temperature capabilities of this instrument. The ESEM also allows direct observation of the effects of sudden and slow changes in the relative humidity as well as the exposure to UV radiation on paint layers under controlled conditions. Other complementary techniques have been used to both characterise the pigments and linseed oils used in this work and to examine the chemical interactions in constructed paint layers. XRD has been used to characterise the dry pigments used in 19th and early 20th century oil paintings and GC-MS was used to characterize a range of linseed oils. Differential Scanning Calorimetry and Thermogravimetry have been used to study the drying kinetics of all the linseed oils used in this work on their own and in combination with pigments to establish the optimum conditions for ESEM analysis. Paint layers have been constructed using similar materials and methods as were used by oil painters in the 19th and early 20th centuries. Dry inorganic pigments of the type used in that era were obtained from an art supplier and chemical suppliers. Each pigment was ground in three types of linseed oil using the traditional muller and glass plate. These were applied in layers to glass slides to avoid influence from ground media or canvas and allowed to dry in the air and in an oven. Pigments that were known to interact strongly were placed in paint layers in direct contact with one another to encourage chemical interaction between the various pigments. In this paper, the key results to date of the present study will be reported. In addition, the practi

  4. Spanish Flu and Early 20th-Century Expansion of a Coronary Heart Disease–Prone Subpopulation

    2004-01-01

    According to Stephen Jay Gould, “we have a strong preference for seeing trends as entities moving somewhere.” However, trends may instead be the product of relative expansions and contractions of different subpopulations constituting the system. Variation in attributes of coronary heart disease cases during the decline in coronary heart disease mortality suggests a change in the primary source-subpopulation of cases over time. It is proposed that an early 20th-century expansion of a coronary heart disease–prone subpopulation, characterized by high serum-cholesterol phenotype and high case-fatality—which contributed to most of the coronary heart disease cases and deaths during the 1960s—may have been a late result of the 1918 influenza pandemic. The same unusual immune response to infection that in 1918 killed preferentially men, whites, and those born from 1880 to 1900 (20–40 years old) may have “primed” survivors of those birth cohorts to late coronary heart disease mortality. Ecologic evidence in favor of a birth cohort and geographic association between both epidemics is presented. Cross-reactive auto-immune response upon reinfection could explain the excess coronary heart disease deaths reported during influenza epidemics from the late 1920s onward. Mimicry between the viral hemagglutinin and the apolipoprotein B or the low-density lipoprotein receptor could be the link between infection and hypercholesterolemia. The extinction of those birth cohorts would result in a relative increase in cases coming from a 2nd subpopulation, which was characterized by insulin resistance and chronic expression of low-grade inflammation markers and was comparatively less vulnerable to die acutely from coronary heart disease.

    According to Stephen Jay Gould, "we have a strong preference for seeing trends as entities moving somewhere." However, trends may instead be the product of relative expansions and contractions of different subpopulations constituting the system. Variation in attributes of coronary heart disease cases during the decline in coronary heart disease mortality suggests a change in the primary source-subpopulation of cases over time. It is proposed that an early 20th-century expansion of a coronary heart disease-prone subpopulation, characterized by high serum-cholesterol phenotype and high case-fatality--which contributed to most of the coronary heart disease cases and deaths during the 1960s--may have been a late result of the 1918 influenza pandemic. The same unusual immune response to infection that in 1918 killed preferentially men, whites, and those born from 1880 to 1900 (20-40 years old) may have "primed" survivors of those birth cohorts to late coronary heart disease mortality. Ecologic evidence in favor of a birth cohort and geographic association between both epidemics is presented. Cross-reactive auto-immune response upon reinfection could explain the excess coronary heart disease deaths reported during influenza epidemics from the late 1920s onward. Mimicry between the viral hemagglutinin and the apolipoprotein B or the low-density lipoprotein receptor could be the link between infection and hypercholesterolemia. The extinction of those birth cohorts would result in a relative increase in cases coming from a 2nd subpopulation, which was characterized by insulin resistance and chronic expression of low-grade inflammation markers and was comparatively less vulnerable to die acutely from coronary heart disease.

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

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

    The 'Heroic Age' of Antarctic exploration, which occurred during the first 15 years of the 20th century, captured headlines around the world. Australia was no exception, especially as Australian scientists played important roles in several expeditions. Through participation in the British Antarctic Expedition of 1907-1909, two Australian scientists - T.W. Edgeworth David (1858-1934) and Douglas Mawson (1882-1958) - became genuine national heroes, mainly through being members of the first party to reach the South Magnetic Pole area. At a superficial level, the vehicle of Antarctic exploration placed science at the forefront of public awareness, fulfilling David's ambition for greater recognition of science and scientists, especially considering the high level of public interest in sport. However, although David and Mawson gave Antarctic exploration a scientific veneer, simply through their status as scientists, the public viewed them as heroes because they had endured great hardships and conquered a point on the map in the name of science and the Empire.

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

  14. The Making and Development of Economic Forms of the Industry of Turkestan Krai in the late 19th – Early 20th Centuries

    2015-06-01

    Full Text Available The period of the late 20th and the early 21st centuries is characterized for many post-socialist countries by profound social/economic transformations. They are going through a tough transition from the implementation of market reform to the formation of a market economy oriented towards innovation development. The historical past of these countries attests that, in a sense, they have already been going through a similar process – back in the late 19th-early 20th centuries. The history of the industry of Turkestan Krai during that period is a vivid example of the process of the making and development of capitalist relations. This proves once again the relevance and timeliness of the study of the characteristics of the evolution of the region’s industry and determination of its prevalent forms. The author examines the initial forms of the region’s industry. Only the penetration of commodity production on the capitalist basis and the resettlement of peasants, the settling down of Kazakhs on the land, the development of old and emergence of new towns and villages, and the construction of railroads would lay the foundation for social division of labor. This spurred the development of old and emergence of new sectors in the industry of Turkestan Krai. During the period under examination, the prevalent form of industry was petty commodity capitalist production. But the transition from craft production and its workshop form to capitalist petty commodity production in Turkestan Krai was a long and not always straightforward process. The author investigates the issue of the making of the factory/plant form of industry. The emergence of particular factories and plants was a consequence of the wide development of Russian capitalism, a result of adopting Central Russia’s accumulated experience in the way of applying production techniques and technology in Turkestan Krai. Based on the author’s study of facts relating to industrial production in Turkestan Krai, the author comes to the conclusion that the region’s development is characterized by a top-bottom line, which stands for capitalist, and a bottom-top line, which denotes ante-capitalist relations.

    2011-11-01

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

  1. Geodiversity and biodiversity interactions in the sand landscapes of the Netherlands on 19th and early 20th century landscape paintings

    Jungerius, Pieter; van den Ancker, Hanneke

    2014-05-01

    Sand landscapes occupy about half of the territory of the Netherlands. Apart from an insignificant amount of Tertiary deposits, these sands are of Pleistocene and Holocene age. They include Saalian push moraines, Weichselian cover sands and Holocene drift sands. To these geological landscapes, cultural variants should be added such as the essen, i.e. a landscape with plaggen soils, and reclaimed lands (e.g. former moors). Not included are the coastal sands, which we dealt with in an earlier EGU contribution (van den Ancker & Jungerius 2012). Nature and man created a wide variety of sceneries that inspired painters in the 19th and early 20th century (Jungerius et al. 2012). Painter communities on the sandy soils flourished in Oosterbeek/Wolfheze, Laren/Blaricum, Nijkerk, Nunspeet/Elspeet, Hattem and Heeze. Many of the landscape paintings are found in the database of Simonis en Buunk that can be freely consulted on line (http//www.simonis&buunk.com). For this presentation we selected specimens that show geodiversity-biodiversity relationships, some of which have changed since. Painters of push moraines were attracted by the rolling terrain, the dry valleys and occasionally the colourful podzol soil profiles. Popular themes in the cover sands were the undulating relief and heathlands with herds of sheep, sandy footpaths and country roads with erosion phenomena. The dynamics of erosion captivated the painters of Holocene drift sand scenery, as did the bare fields of cultivated lands. Their paintings show the rural areas that since the beginning of the 20th century lost their traditional charm in large-scale re-allotment schemes and artificial nature-building project, that changed geodiversity-biodiversity relationships. Changes in the sandy terrains that can be inferred from the paintings are on a landscape scale, the scale of the landform and vegetation type, and are illustrated by changes in colour, pattern, structure and texture. Examples are: · active drift sands with erosional phenomena, most vanished as a result of afforestation and eutrophic precipitation; · wetland heath habitats, that largely disappeared due to reclamation and regional lowering of the groundwater table; · grazing of herded sheep of local breed on geo-structured heathlands, that is recently re-introduced for nature mangement purposes; · smaller agricultural plots on undulating 'essen' with crops such as buckwheat and wheat, now replaced by level terrain and maize monocultures; · monumental old trees on the oldest landscape paintings, often on river banks, are notably absent on later paintings.

    The early years of the 20th century were notable for improvements in general sanitation, dairying practices and milk handling. Most infants were breast-fed, often with some formula feeding as well. Availability of the home icebox permitted safe storage of milk and infant formula, and by the 1920s, feeding of orange juice and cod liver oil greatly decreased the incidence of scurvy and rickets. Use of evaporated milk for formula preparation decreased bacterial contamination and curd tension of infant formulas. From 1930 through the 1960s, breast-feeding declined and cow's milk and beikost were introduced into the diet at earlier and earlier ages. Although commercially prepared formulas, including iron-fortified formulas replaced home-prepared formulas, few infants were breast-fed or formula fed after 4-6 mo of age. Iron deficiency was prevalent. From 1970 through 1999, a resurgence of breast-feeding was associated with a prolongation of formula feeding and an increase in usage of iron-fortified formulas. By the end of the century, formula feeding of older infants had largely replaced feeding of fresh cow's milk and the prevalence of iron deficiency had greatly decreased. PMID:11160571

  5. Nuclear tracks: A success story of the 20th century

    Starting with the observation of a few feeble trails of damage in a sheet of mica exposed to fission fragments some 40 years ago, the discipline based on their correct interpretation has emblazoned a resounding success story in the second half of the 20th century. The spectrum of information revealed by the technique extends from delineating the history of the cosmos over billions of years to observing exotic decays lasting from a minute to a fraction of a second. More, directly useful researches have included medical and biological uses as well as industrial applications. A topic of great current interest is the study of the environmental and health effects of the naturally occurring radon gas. These and other highlights of the track work over the past 40 odd years of the 20th century - with some tentative glimpses of things to come in the 21st - are presented and examined in this review paper

    Full Text Available Since the late 18th century, the Korean traditional medicine trade witnessed a steady growth. There were lots of stores which sold Korean medicinal herbs in Seoul and every major towns had at least one or more stores in Korea, which led to a subsequent growth of people involved in the trade. However, Korean medicine merchants encountered a new environment with the influx of western medicines after the Opening of Ports and the execution of modern medicine policies. Such change of atmosphere led the merchants to seek new breakthroughs. Some of the merchants found the answer in producing and selling patent medicine. The people in the industry had little knowledge of western medicine, so that they had little choice but to combine their experience of Korean medicine with whatever information they had about western counterpart. Such resolution generated a new kind of medicine known as patent medicine. Patent medicine businessmen observed the new medicine policies of the Korean Empire. Some visionary ones even sought to eagerly utilize the trademark system to secure the selling route. The Japanese colonial government strengthened the medicine policies. It revised the legislature and mobilized administrative powers to manage and control the industry. However, such colonial policies in the 1910s implicated certain limits due to its lack of understanding of Korean medicine industry. Also, the colonial government showed poor efforts in introducing modern medicine facilities and systems, so that the ground was set for the patent medicine business to flourish. Patent medicine enjoyed a high turnover. So, the entrepreneurs endeavored to promote the sales in whatever means necessary. The most basic form of advertisement was through the newspaper. Indirect promotion through newspaper articles, issuing medicine flyers, free gift draw, reputation of an influential expert were widely used for its sales. Consequently, patent medicine industry in the 1910s saw a healthy prosperity. One example of such golden days was the case of Hwapyungdangyakbabg(one of the biggest patent medicine companies, which won a third place along with Kyungsungbangjik, which was the top Korean company at that time, in the advertisement design contest hosted by the classified department of Dong-a Daily in 1926.

    The aim of this paper is to understand both continuities and changes in the reference to the Risorgimento in 20th century political discourse. The narrative proceeds by analyzing historical “snapshots,” from the Liberal period to post-Cold War Italy, that allows us to spell out what has changed and what has remained constant in the memorization and actualization of the Risorgimento in the 20th century political discourse. We single out historical events, public rituals and public discourses unfolding in the context of symbolic years and anniversaries of the nation like 1911, 1932, and 1961 where the nexus between the Risorgimento past and the political present came to the fore with particular emphasis. In the contextual discussion of these memorization events, we discuss intellectual elaborations of Risorgimento memorization and indicate how such elaborations spread to wider layers of the populace. In the final section, we bring the analysis up to date by briefly discussing more current interpretations and evocations of the Risorgimento, with a focus on the highly symbolic Presidency of Carlo Azeglio Ciampi (1999-2006).

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

  11. Memoiristics as a Meta-Genre of Historical Literature (through the Example of the Reminiscences of Participants in and Witnesses of the Peasant Movement in Ukraine in the Early 20th Century

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

  13. The Top Ten Astronomical 'breakthroughs' of the 20th century

    Directory of Open Access Journals (Sweden)

    Hughes, D. W.

    2007-10-01

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

  14. FRUIT GROWING IN ROMANIA IN THE 20TH CENTURY

    2002-11-01

    Full Text Available In Romania, fruit growing has an old and rich tradition. During the 20th century, the Romanian fruit growing witnessed dramatic changes. The acreage grown with fruit trees was 340,100 ha in 1927, 184,200 ha in 1950, 428,400 ha in 1970 and 239,900 ha in 1999. Total fruit yield varied during this period of time between 401,100 tons in 1950 and 2,183,000 tons in 1993. In spite of the fact that in 1993 was produced the highest total fruit yield, the average fruit consumption/capita was only of 35.7 kg which is significantly lower than that considered optimal for adult people in temperate zones (62 kg/capita. The main reason of this situation is the poor varietal structure of fruits in which plum trees represented more than 40% of all the fruit trees grown. Another reason would be the low yields/ha registered in all species and cultivars of fruit trees grown in Romania in the last 30-40 years. With a very serious shrink of acreages grown with fruit trees in 1999, the average consumption/capita is expected to become totally unfavorable. There are not many solutions to this problems and one of them certainly means the significant increase of average yields in all fruit species grown in Romania, at least to the level of those achieved in industrial orchards of Western Europe.

    With history writing in general, press history is often linked to the framework of the nationstate. Such nationalist approaches may, however, lead to a fragmented view of history. We should remember that many current European nation states have fairly short histories, and, even old kingdoms, such as Sweden, have changed shape several times. During the 17th and 18th century, the Swedish Empire included Finland, Estonia, Livonia, Ingria, Pomerania, Wismar and Bremen/Verden, and the previously D...

    Cristiani Bereta da, Silva; Ernesta, Zamboni.

    Full Text Available O artigo apresenta análises das relações estabelecidas entre a produção historiográfica e a produção de uma história de Santa Catarina para o uso escolar, no início do século XX. A cultura política republicana era construída e se legitimava como parte de um fenômeno que precisava formular respostas [...] à sociedade sobre variados problemas 'herdados do Império' que impediam o progresso do Brasil. No caso dos catarinenses, era preciso enfrentar o desafio de uma educação cívico-patriótica num território em que o sistema escolar, precário, ainda lidava com o problema da língua, posto que em muitas escolas falava-se alemão ou italiano, por exemplo. Estas questões são problematizadas por meio da análise da produção sobre a história de Santa Catarina pelo Instituto Histórico e Geográfico Catarinense (criado em 1896), de manuais didáticos que circularam nesse período, programas e relatórios de ensino. O objetivo é contribuir para o estudo das relações entre ensino de História e cultura política, buscando compreender como o ensino de História participou, naquele período, de projeções simbólicas sobre o futuro do Brasil, a partir de leituras compartilhadas de seu passado. Abstract in english This article analyzes the relations weaved between historiographic production and the production of a history of Santa Catarina for school use in the early 20th century. Republican political culture was constructed and legitimated as part of a phenomenon which needed to formulate answers for society [...] regarding several 'Empire-inherited' issues holding back progress in Brazilian. In the case of Santa Catarina, one of the issues faced was the challenge of patriotic education in a territory where the precarious school system also had to deal with the issue of language, since in several schools the language spoken was German or Italian. These issues are analyzed through the production of the history of Santa Catarina history, consisting of the didactic material published at that time, such as teaching programs and reports, by the Instituto Histórico e Geográfico Catarinense (created in 1896). The objective is to contribute to discussions about the relation between history teaching and political culture, in the sense of understanding the ways in which the teaching of history participated, in the early 20th century, in symbolic projections of the future of Brazil through shared readings of their past.

  17. Global physical water scarcity trajectories for the 20th century

    Food security and the overall wellbeing of human kind are threatened by overexploitation of our freshwater resources. Water scarcity is not only a threat to people, but also to many of the planet's key ecosystems. Due to increasing population pressure, changing water consumption behaviour, and climate change, the threat is projected to become even worse in the future. Water can be physically scarce in two ways: population-driven water shortage occurs in areas where a large population has to depend on a limited resources (indicated by m3/capita/yr), while demand-driven water stress is related to the excessive use of otherwise sufficient water resources (indicated by demand/supply ratio). Although many studies have increased our understanding of current water scarcity and how this may increase in the future, the understanding of trajectories with the past development of the water scarcity is less well understood. To date, studies of past water resources have focused on either water shortage or water stress. We aim to calculate global water scarcity, both water stress and water shortage, for the period 1900-2005. We can thus provide, for the first time, continuous regional trends and local analyses of trajectories of water scarcity for the entire 20th century. By including both dimensions of water scarcity, we can increase the understanding of reasons behind the scarcity. We found that in year 1900 13% of the population (i.e. 0.22 billion people) was living in areas that suffer some kind of water scarcity (0.2), while in year 2005 this percentage has increased to 57% (3.80 billion). Especially the population suffering from both high water stress (ratio >0.4) and high water shortage (stress and water shortage, to illustrate trajectories of how water scarcity develops for different regions. Insights into these trajectories can help to understand possible measures to alleviate water scarcity for different regions and support macro-scale analysis and planning to tackle with the future challenges in terms of water scarcity.

  1. Ionizing radiation in the 20th century and beyond

    International Nuclear Information System (INIS)

    Ionizing radiation and radioactivity have been subjected to very different evaluations since their discovery in the late 19th century. This is due to their potential effects, which are beneficial in medical diagnosis and treatment as well as in technical applications, and cause damage at high doses. In the light of the early finding that high doses are harmful, some first concepts limiting the exposure to manmade radiation were elaborated in the twenties of the last century. They were based on effects detectable at an early stage, and were lowered step by step as far as dose limits were concerned. The question about possible genetic effects, which was still open in the fifties, and the definition of the linear dose - effect hypothesis, resulted in further decreases of limits. It is doubtful to what extent current levels can be justified and are able to protect the health and lives of people, given the limited financial resources available to protect the public. In connection with the debate about the peaceful uses of nuclear power and the necessary final storage of radioactive waste, possibly in repositories in deep underground geologic formations, attention should be drawn to two natural facts: Natural sources annually release 2 to 5 orders of magnitude more radioactive substances into the atmosphere than all manmade sources taken together. The cumulated activities released by all nuclear power plants worldwide today roughly correspond to the natural activities of approx. 3 km3 of terrestrial rock in some 500 years. Accordingly, the human contribution to the natural flow of radioactivity is rather minimal, especially as it can be controlled and limited. (orig.)

  2. ???????????? ?? ??????? ??????? ? ????????????? ????? ?? 20 ??? : The theology of the Divine energies in 20th century Orthodox thought

    Tanev, Stoyan

    2012-01-01

    The dissertation was part of an individual doctoral research program as an external scholar in the Faculty of Theology at Sofia University, Bulgaria. It suggests a comprehensive study of the concept of energy in Orthodox theology and physics. It consists of a historical, dogmatic and empirical component. The first chapter discusses the re-emergence of the distinction between Divine essence and energies in Orthodox theology by focusing on the sophiological controversy in the first half of 20th century with a specific emphasis on the theology of Fr. Georges Florovsky and Fr. Sergius Bulgakov. The analysis points out the role of Fr. G. Florovsky for the rediscovery of the teaching on the Divine essence and energies as one of his key theological contributions by focusing on some of his letters to Bulgakov that were written as early as 1925 and on his work Creature and creaturehood (1927). The analysis suggests that these early works have determined the main direction of Orthodox theological reflection in the 20thcentury. Chapter II of the dissertation focuses on a comparative analysis of the theological insights of three key Orthodox theologians: Metropolitan John Zizioulas (1931 ?), Fr. Dumitru Staniloae (1903 ? 1993) and Fr. John Romanides (1927?2001). Metropolitan John Zizioulas is a Greek theologian who is currently the main theological representative of the Ecumenical Patriarchate of Constantinople, New Rome. Fr. D. Staniloae is a Romanian theologian who provided one of the most comprehensive theological syntheses in the 20th century. Fr. Romanides is a Greek-born American theologian who returned to Greece and became one of the main drivers of the renewal of Greek Orthodox theology in the 20th century. These three theologians have significantly contributed to Orthodox theology in the 20th century and have addressed the teaching on the Divine energies in different ways. Fr. D. Staniloae and Fr. John Romanides included the teaching on the Divine energies as an integral part of their theological systems. Metr. John Zizioulas adopted a different approach trying to demonstrate that the teaching on the Divine energies is not essential in Orthodox theology. The dissertation suggests a comparative analysis of the three theologians to show that neglecting the teaching on the energies leads to a narrower understanding of both spiritual life and the Church. Chapter III provides a parallel study of the term energy in Orthodox theology and physics. Its intention is to build on existing works and established knowledge to provide a basis for the development of an interdisciplinary analytical framework in contribution to the ongoing contemporary dialogue between science and theology. The Chapter starts with a discussion of the methodological grounds for the parallel exploration of the concept of energy in Orthodox theology and physics by focusing on the ‘analogical isomorphism’ approach. Afterwards it provides a more detailed articulation of the ways the concept of energy is used in physics and Orthodox theology by concentrating on the history, content and major issues related to two debates, the first one, between two monks - Barlaam the Calabrian and St Gregory Palamas - in 14th century Byzantium, and, the second, between two great physicists - Niels Bohr and Albert Einstein - in the 20th century. The qualitative comparative analysis approach was found to be particularly fruitful. It builds on insights from Eastern Christian (Byzantine) theology, philosophy of science and philosophy of religion to suggest an analysis of the way of using language in theology and quantum mechanics. The Chapter concludes by summarizing the observations emerging from the analysis and a number of conclusions related to their potential value for the science-theology dialogue.

    Full Text Available El presente artículo busca responder en qué sentido la lucha antivenérea en Antioquia a finales del siglo XIX y principios del XX, parte del dispositivo higienista, fue una lucha contra la inmoralidad. Para su construcción se realizó revisión bibliográfica de fuentes secundarias. El proyecto regional en su dimensión ética-cultural incluyó una apuesta modernizadora, a cargo de los médicos, ajustada a la moral puritana promovida por la Iglesia, para ello emprendieron una lucha antivenérea que consistió en ilustrar a las masas populares: se debía reservar la sexualidad a la familia y reprochar moralmente a la población donde aparecían dichas enfermedades. Así, el discurso médico-científico juzgó las prácticas de los sectores populares mientras los hombres de ciencia ingresaban al escenario social con poder por tener jerarquía moral. This article aims to define in what ways the anti-venereal fight in Antioquia, during the late 19th and early 20th centuries, which was part of the hygienic device, was really a fight against the immorality. In order to write it, secondary bibliographic sources were revised. In its ethical and cultural dimension, the regional project included a modernizing project. Doctors were in charge of this project which was adjusted to fit the puritan moral the Church promoted. They began a fight against sexual transmission diseases tah was bases upon illustration of communities: sexuality was to be reserved to family environments and populations where diseases appeared should be morally rejected. An so, medical scientific speech be judged low class populations` actions while men of science entered the social scenario with power from having moral hierarchy.

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

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

    Full Text Available The aim of this article is to provide an overview of translations of English literature into Estonian between 1779 and 1917. There is an attempt to analyse the texts by describing them on the basis of, or in their departure from, a text or texts that chronologically and logically precede them. The discussion includes the nature of the transfer and the changes that have been made to the text, either because they existed in the source or mediating text or because of the expectations or requirements in the receptor, i.e. Estonian culture. The translated texts are seen in their historical-cultural context. For the analysis, a corpus of translated texts – religious, fiction, drama and non-fiction (published in a book form was compiled. The general orientation of Estonia until the 1880s was to the German cultural sphere. So the first translations of English literature were made via a mediating language, which was German. English Puritan writers were introduced by the Pietist missionaries with the aim of spreading their teachings in the second half of the 18th century. At about the same time the narrative element was introduced into stories with religious content. Some internationally popular stories, e.g. the Inkle and Yarico story, later robinsonades, stories of slavery and plant at ion life, as well as Amer ican Indian st or ies wer e also t r anslat ed fr om Ger man. However, until  1875  ver  y  few  translations  of  English  literature  into  E stonian were  published.  The  last quarter of the 19th century saw an explosion in literary production: there was a substantial increase  both  in  the  number  of  translations  of  English  literature  into  E stonian  as  well  as diversification of genres. This continued into the first decade of the 20th  centur y,  when  the sociopolitical situation in Estonia changed. In addition, books came to be translated directly from  English,  although  many  translations  of  English  literature  were  still  made  via  German and, to a lesser extent, via Russian, Swedish or Finnish. Thus, English literature often reached the Estonian audiences in a mediated form. The selection of authors and books, the structure of the texts and the overall meaning and tone of the texts often depended on the mediating text or culture. However, many changes were made by the translator: explanations of new words and phrases, pronunciations, references to the Estonian reader, etc. Here paratexts are quite important: the titles often explained the content or the purpose of the book and referred to the language from which the book was translated. In the prefaces, translators or publishers explained their aims or connected the book to discussions in society (e.g. the translator of Uncle Tom’s Cabin connected it to anabolitionist argument of slavery as a moral evil; on the other hand, the editor connected it to the Estonian fight for freedom; the translation of The Pathfinder was related to the polemics in the Estonian newspapers over migration. However, in very many cases it was difficult to positively identify the mediating or source language or text and to establish whether it was a translation of English literature.

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

    International Nuclear Information System (INIS)

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

  13. Increasing cloud cover in the 20th century: review and new findings in Spain

    Full Text Available Visual observations of clouds have been performed since the establishment of meteorological observatories during the early instrumental period, and have become more systematic and reliable after the mid-19th century due to the establishment of the first national weather services. During the last decades a large number of studies have documented the trends of the total cloud cover (TCC and cloudy types; most of these studies are focused on the trends since the second half of the 20th century. Due to the lower reliability of former observations, and the fact that most of this data is not accessible in digital format, there is a lack of studies focusing on the trends of cloudiness since the mid-19th century. In the first part, this work attempts to review the previous studies analyzing TCC changes with information covering at least the first half of the 20th century. Then, the study analyses a database of cloudiness observations in Southern Europe (Spain since the second third of the 19th century. Specifically, monthly TCC series were reconstructed since 1866 by means of a so-called parameter of cloudiness, calculated from the number of cloudless and overcast days. This estimated TCC series show a high interannual and decadal correlation with the observed TCC series originally measured in oktas. After assessing the temporal homogeneity of the estimated TCC series, the mean annual and seasonal series for the whole of Spain and several subregions were calculated. The mean annual TCC shows a general tendency to increase from the beginning of the series until the 1960s; at this point, the trend becomes negative. The linear trend for the annual mean series, estimated over the 1866–2010 period, is a highly remarkable (and statistically significant increase of +0.44% per decade, which implies an overall increase of more than +6% during the analyzed period. These results are in line with the major part of the previous trends observed at many areas of the World, especially for the records before the 1950s, when a widespread increase of TCC can been considered as a common feature.

  14. What was Glaucoma Called Before the 20th Century?

    Leffler, Christopher T.; Schwartz, Stephen G.; Giliberti, Francesca M.; Young, Matthew T.; Bermudez, Dennis

    2015-01-01

    Glaucoma involves a characteristic optic neuropathy, often with elevated intraocular pressure. Before 1850, poor vision with a normal eye appearance, as occurs in primary open-angle glaucoma, was termed amaurosis, gutta serena, or black cataract. Few observers noted palpable hardness of the eye in amaurosis. On the other hand, angle-closure glaucoma can produce a green or gray pupil, and therefore was called, variously, glaucoma (derived from the Greek for glaucous, a nonspecific term connoting blue, green, or light gray) and viriditate oculi. Angle closure, with palpable hardness of the eye, mydriasis, and anterior prominence of the lens, was described in greater detail in the 18th and 19th centuries. The introduction of the ophthalmoscope in 1850 permitted the visualization of the excavated optic neuropathy in eyes with a normal or with a dilated greenish-gray pupil. Physicians developed a better appreciation of the role of intraocular pressure in both conditions, which became subsumed under the rubric “glaucoma”. PMID:26483611

  20. Progress in Reconstructing 20th Century Oceanic Precipitation

    Global land and ocean precipitation analyses are available using satellite data beginning 1979. Prior to 1979 gauge data provide coverage for much of the land, but over oceanic regions there are only a few island gauges. In recent years attempts have been made to reconstruct large-scale oceanic precipitation variations using the sparse gauge network and large-scale spatial covariance. Covariance statistics are based on analyses using satellite data. Sufficient gauge observations are available to permit reconstructions to begin as early as 1900, providing a time series more than 100 years in length. Earlier reconstruction efforts have resolved ENSO variations, which have large scales and strong signals. Recent studies at ESSIC/CICS have improved these reconstructions by using a new, more homogeneous satellite analysis for statistics and improved tuning of the method. This has improved reconstruction skill of interannual variations over the Northern Hemisphere extra-tropical oceans, and allowed reconstructions to be extended to 1900. However, the gauge-based methods do a poor job at oceanic inter-decadal variations for the satellite period. To address that problem, a new method was developed using a CCA to compute the annual-average precipitation anomaly from annual-averages of sea-level pressure and sea-surface temperature anomalies. Initial results suggest that this method resolves the large-scale inter-decadal variations. At present we are developing a two-part reconstruction, using the CCA-based method to analyze inter-decadal variations and the gauge-based analysis to resolve interannual variations. An improved, longer homogeneous satellite- period analysis is also under development to provide improved reconstruction statistics. Progress toward the goal of a comprehensive global precipitation product beginning in 1900 will be discussed.

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

  3. A Revised Estimate of 20th Century Global Mean Sea Level

    One of the primary goals of paleo-sea level research is to assess the stability of ice sheets and glaciers in warming climates. In this context, the 20th century may be thought of as the most recent, recorded, and studied of all past episodes of warming. Over the past decade, a consensus has emerged in the literature that 20th century global mean sea level (GMSL), inferred from tide gauge records, rose at a mean rate of 1.6-1.9 mm/yr. This sea-level rise can be attributed to multiple sources, including thermal expansion of the oceans, ice sheet and glacier mass flux, and anthropogenic changes in land water storage. The Fifth Assessment Report of the IPCC summarized the estimated contributions of these sources over 1901-1990 and computed a total rate, using a bottom-up approach, of ~1.0 mm/yr, which falls significantly short of the rate inferred from tide gauge records. Using two independent probabilistic approaches that utilize models of glacial isostatic adjustment, ocean dynamics, and the sea-level fingerprints of rapid land-ice melt to analyze tide gauge records (Kalman smoothing and Gaussian process regression), we are able to close the 20th century sea-level budget and resolve the above enigma. Our revised estimate for the rate of GMSL rise during 1901-1990 is 1.1-1.3 mm/yr (90% credible interval). This value, which is ~20-30% less than previous estimates, suggests that the change in the GMSL rate from the 20th century to the last two decades (2.7 ± 0.4 mm/yr, consistent with past estimates) was greater than previous estimates. Moreover, since some forward projections of GMSL change into the next century are based in part on past estimates of GMSL change, our revised rate may impact projections of GMSL rise for the 21st century and beyond.

  4. How in the 20th century physicists, chemists and biologists answered the question: what is life?

    International Nuclear Information System (INIS)

    The most essential achievements in 20th century biology are analyzed and the question of how throughout the last century physicists, chemists and biologists answered the question 'What is life?' is considered. The most considerable scientific achievement of 20th century biology, and perhaps of all science, is considered by many to be the discovery by biologist J Watson and physicists F Crick and M Wilkins that resulted in establishing the DNA structure. The related work of well-known scientists of the USA and Europe, E Schroedinger, L Pauling, M Perutz, J Kendrew, and of the Russian scientists N K Koltsov, N V Timofeeff-Ressovsky, G A Gamow, A M Olovnikov, is analyzed. Presently, when the structure of DNA, the process of gene expression and even the genomes of human beings are already known, scientists realize that we still do not know many of the most important things. In our opinion, the 20th century studies of nucleic acids largely ignored the principle of the cyclic organisation of DNA. In this connection, we analyze the principle of cyclicity, which in its generality may well complement the concept of the atomic structure of matter. (from the history of physics)

  13. The process of Danish nurses' professionalization and patterns of thought in the 20th century.

    Beedholm, Kirsten; Frederiksen, Kirsten

    2015-06-01

    In this article, we address how the professionalization process is reflected in the way Danish nursing textbooks present 'nursing' to new members of the profession during the 20th century. The discussion is based on a discourse analysis of seven Danish textbooks on basic nursing published between 1904 and 1996. The analysis was inspired by the work of Michel Foucault, in particular the concepts of rupture and rules of formation. First, we explain how the dominating role of the human body in nursing textbooks disappears in the mid-20th century. This transformation can of course be attributed to changes in tasks and responsibilities for nurses or to the implementation of increasing amounts of knowledge and theories from other disciplines than medicine into the nurses' knowledge base. However, inspired by Foucault, we consider these historical changes to be the conditions of possibilities and not causes. The second part of the analysis shows that along with 'the disappearance of the body', a second discursive change appears: the role of doctors and medicine changes fundamentally from about mid-20th century. Finally, we argue that this discursive reorganization enabling new patterns of thought to emerge was driven by a professional interest in describing nursing as an independent profession.

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

    Since systematic measurements of Louisiana continental-shelf waters were initiated in 1985, hypoxia (oxygen content area termed the dead zone. Monitoring and modeling studies have concluded that the expansion of the Louisiana shelf dead zone is related to increased anthropogenically derived nutrient delivery from the Mississippi River drainage basin, physical and hydrographical changes of the Louisiana Shelf, and possibly coastal erosion of wetlands in southern Louisiana. In order to track the development and expansion of seasonal low-oxygen conditions on the Louisiana shelf prior to 1985, we used a specific low-oxygen foraminiferal faunal proxy, the PEB index, which has been shown statistically to represent the modern Louisiana hypoxia zone. We constructed a network of 13 PEB records with excess 210Pb-derived chronologies to establish the development of low-oxygen and hypoxic conditions over a large portion of the modern dead zone for the last 100 years. The PEB index record indicates that areas of low-oxygen bottom water began to appear in the early 1910s in isolated hotspots near the Mississippi Delta and rapidly expanded across the entire Louisiana shelf beginning in the 1950s. Since ~1950, the percentage of PEB species has steadily increased over a large portion of the modern dead zone. By 1960, subsurface low-oxygen conditions were occurring seasonally over a large part of the geographic area now known as the dead zone. The long-term trends in the PEB index are consistent with the 20th-century observational and proxy data for low oxygen and hypoxia.

    Full Text Available Plots reeled into the ekphrasis have always existed. In belles lettres of the beginning of the 20th century, the fight between the pagan and the Christian manifests in the opposition of scenic space and it creates a powerful «magnetic» field. This is a special type of mythologism in which the Christian imagery is on the positive side of the binary opposition with its respective system of ethical coordinates. In «polytheistic systems, the presentations of evil is static as of the essential and eternal beginning of the world», but in the orthodox Christianity, the devil is a ghost, lure, disembodied temptation and «with every day it approaches nonexistence» (from the «Moralia» of the 6th century by Gregory the Great. However, Gregory the Great also notes that the power of Satan is from God as all other powers, he just distorted his power with his God-given free will. Even at the level of worldly wisdom aphorisms there is a conventional belief that our shortcomings are the continuation of our merits, and therefore it is necessary to adhere to the golden mean. Accroding to A. Gracheva in the book «Dialogues of Janus: Belles lettres and classics in the Russian literature of the early twentieth century», at the beginning of the 19th century, the mythologism of the spontaneous and not experimental type (often encyclopaedic and «algebraic» like in the works of Joyce and Bely, is especially pronounced in the works of writers, who are close to mass literature with their democracy or «boudoir» and especially in the works of female writers. This is due both to existing archetypes of the collective unconscious (some of which are even atavistic and «migratory plots» which are characteristic of both folklore and popular culture. Despite the compelling erotic subject matter, belles lettres is not always frivolous and, on the contrary, it is edifying and full of moral questions, which are sometimes rhetorical: «What is a sin and what does the evil mean? I’m going through my memory, what interesting things I heard and read about love, about the rights of genders, flesh, and find different clever words. But that’s just words ... They do not illuminate my soul with the understanding «(from the story of Avgusta Damanskaya» One day», published in the seventh issue of the «Education» magazine for 1908.

    Full Text Available This paper investigates the changes in precipitation levels in Croatia that can be observed since the mid 20th century. Based on the data from 22 weather stations, linear trends show very little oscillation for the period 1950–2010. In eastern Croatia, a slight increase was recorded, while a slight drop or stagnation was evident in other parts of the country. However, were such trends to continue, they could have long-term geographic consequences. In the analytical period, it is possible to determine cyclical changes in the annual levels of precipitation.

Our results show that siblings of centenarians, who share half of their genes and a common childhood environment,lived 3–4 years longer than their birth cohort. However, husbands and wives of centenarians lived 4 and 2.5 years longer than theircounterparts of the same sex, respectively, suggesting that longevity is also modulated by shared environment in adulthood.

    2007-01-01

    At the beginning of the 20th century the pulp industry in Sweden faced major problems with waste. Pine and spruce contain at the best 40 % cellulose. The remainder was released into the air and water, causing major environmental problems. In 1909 two Swedish engineers patented a method to ferment sulphite lye into alcohol. Apart for consumption, the alcohol could be used as fuel. The rest of the lye, reduced of it’s saccariferous contents, was expected to become the basis of a new chemical in...

    The Little Ice Age maximum extent of glaciers in Iceland was reached about 1890 AD and most glaciers in the country have retreated during the 20th century. A model for the surface mass balance and the flow of glaciers is used to reconstruct the 20th century retreat history of Hoffellsjökull, a south-flowing outlet glacier of the ice cap Vatnajökull, which is located close to the southeastern coast of Iceland. The bedrock topography was surveyed with radio-echo soundings in 2001. A wealth of data are available to force and constrain the model, e.g. surface elevation maps from ~1890, 1936, 1946, 1989, 2001, 2008 and 2010, mass balance observations conducted in 1936-1938 and after 2001, energy balance measurements after 2001, and glacier surface velocity derived by kinematic and differential GPS surveys and correlation of SPOT5 images. The approximately 20% volume loss of this glacier in the period 1895-2010 is realistically simulated with the model. After calibration of the model with past observations, it is used to simulate the future response of the glacier during the 21st century. The mass balance model was forced with an ensemble of temperature and precipitation scenarios derived from 10 global and 3 regional climate model simulations using the A1B emission scenario. If the average climate of 2000-2009 is maintained into the future, the volume of the glacier is projected to be reduced by 30% with respect to the present at the end of this century. If the climate warms, as suggested by most of the climate change scenarios, the model projects this glacier to almost disappear by the end of the 21st century. Runoff from the glacier is predicted to increase for the next 30-40 yr and decrease after that as a consequence of the diminishing ice-covered area.

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

    Full Text Available The aim of the paper is to present the history of the Podsused reading rooms and library in the 20th century, using the original archival material. The materials stored in the Croatian State Archives, original printed and hand-written Regulations of reading associations, minutes of general meetings, and documents of other associations describe the organizational and operational features of reading rooms. In addition, private documents and photos of the citizens of Podsused were also used to reconstruct the operation and influence of the Susedgrad reading room on the life in Podsused. They recorded rich cultural activities of the reading association and its role in the cultural and public life of Podsused. The first readership associations were established in Podsused under the influence of the readership movement in Croatia: The Susedgrad reading room (1913, which was renamed in 1923 to the Croatian Reading Room of Podsused and the Croatian Reading Room Croatia in Podsused, located in the factory canteen of the Portland Cement Works (1923. The today's Library and Reading Room for Children and Adults was opened in 1951 in Dom kulture in Podsused, and has been working ever since. The main contribution of the paper is the identification of core features of the development of librarianship in Podsused in the 20th century.

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

    International Nuclear Information System (INIS)

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

    Full Text Available Holiday memories maintain the continuity of a society with the past and help keep the past alive in the memory of the community. The holiday calendar of the Yugoslav and Serbian state in the second half of the 20th century changed with every regime change, which meant that the contents of holiday memories changed along. The culture of memory in Serbia during socialism served the purpose of “socializing” the society, but also imprinting the achievements of the people’s liberation war into the consciousness of the people. In the holiday culture of memory in Serbia after 2000 political holidays are intertwined as symbols with the newly established tradition of remembering events from the first half of the 19th century, as well as religious holidays with roots in the mythical past.

  10. High resolution sedimentary record of dinoflagellate cysts reflects decadal variability and 20th century warming in the Santa Barbara Basin

    2014-12-01

    We present a continuous record of dinoflagellate cysts from a core of laminated sediments collected in the Santa Barbara Basin (SBB), off Southern California. The core spans the last ?260 years and is analysed at biennial (two-year) resolution. Variations in dinoflagellate cyst assemblages are compared with 20th century historical changes, and are used to examine changes in primary productivity and species composition, which are bound to the variability in upwelling and sea-surface temperature (SST) in the region. Cysts produced by heterotrophic dinoflagellates dominate the assemblages. In particular, Brigantedinium spp. (on average 64.2% of the assemblages) are commonly associated with high levels of primary productivity, typically observed under active upwelling conditions, when nutrient supply is higher. Other heterotrophic taxa such as cysts of Protoperidinium americanum, Protoperidinium fukuyoi, Protoperidinium minutum and Archaeperidinium saanichi, all Echinidinium species, Quinquecuspis concreta and Selenopemphix undulata are more abundant in the early part of the record (?1750s-1870s). These taxa are generally associated with high primary productivity and are observed predominantly during intervals marked by relatively variable conditions of SST, stratification and nutrient loading. The 20th century is marked by an increase in several species of autotrophic affinity, primarily Lingulodinium machaerophorum and Spiniferites ramosus. In recent surface sediments from the region, these species are more abundant in the Southern California Bight, and they are associated with conditions of relaxed upwelling in the SBB (typically observed during summer and fall), when SST is higher and nutrient supply is moderate. Their increasing concentrations since the early 20th century reflect warmer SST and possibly stronger stratification during the warmest season. Taken together, the changes in cyst assemblages provide further evidence that persistently warmer conditions in the SBB began affecting marine populations by the late 1920s. Decadal-scale variations in primary productivity are encoded in the heterotrophic dinoflagellate cyst record, with higher (lower) concentrations of heterotrophic taxa occurring during "cool" ("warm") phases of the Pacific Decadal Oscillation (PDO) index. Wavelet analysis of heterotrophic taxa concentrations suggests a weaker influence of the PDO on biota of the region during the 19th century.

  11. Organic petrology in the 19th, 20th, and 21st centuries: The Newcastle contribution

    2005-04-12

    The paper describes the development of coal petrology, then organic petrology, over a period of approximately 175 years around and in Newcastle upon Tyne (England). From 1833 until 1950, the basis of study was essentially transmitted light microscopy. In this period, perhaps the supreme contribution was the work of Hutton, Lindley, and Witham, who demonstrated the vegetable nature of coal in 1833. A major Scottish legal case, the 'Boghead Controversy' of 1853, in which 'Newcastle' was much later to be involved, was not finally resolved until Blackburn and Temperly confirmed the true nature of the relationship between the modern alga Botryococcus and the algal coals some 80 years later. In the early part of the 20th century, works by Hickling on the 'coal belt' and Hickling and Marshall on the cell structures of vitrinites were important as was Raistrick's substantial contribution to the founding of the field of palynology through his microspore correlation studies on coal seams from the coalfields of northeast England and Lancashire.Large-scale organisational changes in the Department of Geology at Newcastle in the period 1950 to 1989 took place with the development of the Organic Geochemistry Unit (OGU) in which organic petrology was a major component. Organic petrology and organic geochemistry were major components. There was almost entire replacement of transmitted light microscopy by reflected light procedures as the principal means of studying crustal organic matter microscopically. Widespread collaboration with industry, particularly with oil companies, which, with the University and the Research Councils, provided invaluable support to the research group over many years. Considered here are the results of investigations across the expanding field of organic petrology, covering the development of equipment and relationships between maceral properties, the varied effects of carbonisation treatments, and the influence of igneous activity on crustal organic matter.There were further radical changes in the composition of the research group after the completion of the national Earth Science Review in 1989. The Institute of Fossil Fuels and Environmental Geochemistry (FFEGI) was formed with a further substantial increase of both staff and postgraduate students. Organic petrology as a component was much reduced, although reflected light studies continued on coals from the offshore coalfields of northeast England, and transmitted light studies, almost exclusively related to the study of organic facies, returned. The output of organic petrologists virtually ceased. Most effective research groups, however, shift their emphases with time. FFEGI occupied a substantial and successful international research niche within the environmental field, as well as being still heavily committed to petroleum geochemistry until 2003 when FFEGI was integrated within the new School of Civil Engineering and Geosciences.

  13. Rapid changes in the seasonal sea level cycle along the US Gulf coast from the late 20th century

    2014-01-01

    Temporal variations of the seasonal sea level harmonics throughout the 20th and early 21st century along the United States Gulf coast are investigated. A significant amplification of the annual sea level cycle from the 1990s onward is found, with both lower winter and higher summer sea levels in the eastern Gulf. Ancillary data are used to build a set of multiple regression models to explore the mechanisms driving the decadal variability and recent increase in the annual cycle. The results suggest that changes in the air surface temperature toward warmer summers and colder winters and changes in mean sea level pressure explain most of the amplitude increase. The changes in the seasonal sea level cycle are shown to have almost doubled the risk of hurricane induced flooding associated with sea level rise since the 1990s for the eastern and north-eastern Gulf of Mexico coastlines.

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

  16. Causes of mortality and development: Evidence from large health shocks in 20th century America

    DEFF Research Database (Denmark)

    Worm Hansen, Casper

    2012-01-01

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

    The following calendar systems, introduced in Europe from 18^{th} to 20^{th} century, which were in use for a shorter or longer period by a larger or smaller community, were reviewed and discussed: The French Revolutionary Calendar, the Theosebic calendar invented by Theophilos Kairis, the Revolutionary Calendar of the Soviet Union (or 'Bolshevik calendar'), the Fascist calendar in Italy and the calendar of the Metaxas dictatorship in Greece before World War II. Also the unique of them, which is still in use, the New Rectified Julian calendar of the Orthodox Church, adopted according to proposition of Milutin Milankovi? on the Congress of Orthodox Churches in 1923 in Constantinople, is presented and discussed. At the end, difficulties to introduce a new calendar are discussed as well.

    Directory of Open Access Journals (Sweden)

    Simon Krek

    2013-05-01

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

  20. Long-term non-linear predictability of ENSO events over the 20th century

    Astudillo, H F; Borotto, F A

    2015-01-01

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

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

    CERN Document Server

    Petkov, V B

    2000-01-01

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

    2015-06-01

    The regional analysis of extreme hydrological events is connected with the availability of a dense network of rainfall data that is absent or inaccessible in Brazil, especially for sub-daily information. In engineering, extreme events rainfall information is represented by intensity-duration-frequency (IDF) relationships which are the most commonly used tools in water resources engineering for planning and design. Even if the sub-daily information that is included in the relationships is not available, the extreme rainfall information rest in the fundamentals of the IDF. This paper analyzes spatial distribution and track changes in sub-daily precipitation over Northeastern (NE) Brazil. Precipitation was estimated from IDF relationships information in Brazil based in rainfall measured from 1920's to 1950's (but still used in engineering projects) and information from the last half of the 20th century obtained from several IDFs gathered from municipalities' manuals, local symposia and books in many cases not easily obtainable. Results showed an intensification of extreme events in recent years, especially in shorter duration rainfall (less than 12 h). Hourly rainfall is bigger in almost all the Brazilian region, but especially in littoral and Northern portion, however, 12 and 24 h rainfall exhibit increases in the North, but, lower values in the Southern half of the region in concordance with flood changes reported by Milly et al. (2005). Analyzing the ratio between 1 and 24 h rainfall is possible to confirm its increase in all the region, with up to 35% in some areas. These results were able to show insight of sub-daily extreme events changes during 20th century in NE Brazil were previous reports were not found. The results also alerts for the necessity of engineering projects review, as outdated information is still being used for design purposes.

  4. Ice core evidence for a 20th century decline of sea ice in the Bellingshausen Sea, Antarctica

    This study uses ice core methanesulphonic acid (MSA) records from the Antarctic Peninsula, where temperatures have been warming faster than anywhere else in the Southern Hemisphere, to reconstruct the 20th century history of sea ice change in the adjacent Bellingshausen Sea. Using satellite-derived sea ice and meteorological data, we show that ice core MSA records from this region are a reliable proxy for regional sea ice change, with years of increased winter sea ice extent recorded by increased ice core MSA concentrations. Our reconstruction suggests that the satellite-observed sea ice decline in the Bellingshausen Sea during recent decades is part of a long-term regional trend that has occurred throughout the 20th century. The long-term perspective on sea ice in the Bellingshausen Sea is consistent with evidence of 20th century warming on the Antarctic Peninsula and may reflect a progressive deepening of the Amundsen Sea Low due to increasing greenhouse gas concentrations and, more recently, stratospheric ozone depletion. As a first-order estimate, our MSA-based reconstruction suggests that sea ice in the Bellingshausen Sea has retreated southward by ˜0.7° during the 20th century. Comparison with other 20th century sea ice observations, reconstructions, and model simulations provides a coherent picture of Antarctic sea ice decline during the 20th century, although with regional-scale differences evident in the timing and magnitude of this sea ice decline. This longer-term perspective contrasts with the small overall increase in Antarctic sea ice that is observed in post-1979 satellite data.

  5. AN ANALYSIS OF THE DIFFERENTIATION STRATEGIES OF RURAL FOUNDRIES IN THE BEGINNING OF THE 20TH CENTURY IN THE PROVINCE OF QUEBEC

    2009-01-01

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

    Frequency and intensity of heavy rainfalls, triggering floods and causing human and large economic losses, are expected to increase in the context of the global warming, due to the larger water carrying capacity of warmer air masses. However, the relationship between such events and climatic changes remains still poorly understood. In particular, the stability of the flood-prone atmospheric circulations under future climate changes is a key question for projections of extreme precipitation. This study aims at exploring this issue using flood reconstructions from the NW Mediterranean domain. We compiled existing historical records from the Southern Massif Central and lake-sediment records from the Eastern Pyrenees and the Southern French Alps. We completed this West-East transect by studying new lake sequences in the SE French Alps and the Western Italian Alps. For both of the new lake sediment sequences (Lake Foréant, Queyras massif, France and Lago Inferiore di Laurès, Aosta valley, Italy), several short cores were retrieved to understand the sedimentary processes. In the laboratory, high-resolution pictures, bulk density, geochemistry and grain size were measured. Dating was undertaken by short-lived radionuclides (EAWAG, Zürich) and radiocarbon (University of Bern) measurements. Lago Inferiore sequence covers the last 250 years and Lake Foréant sequence the last millennium. 232 turbidites were identified; 11 of which seem to be related to mass movements, whereas the other 221 were triggered by flood events. The reconstructed flood regimes were then compared to local flood activity based on historical data. The good agreement between the datasets supports the quality and sensitivity of flood reconstructions. In the NW Mediterranean domain, floods and related heavy rainfalls are mostly triggered by autumn humid air masses coming from the Mediterranean Sea. In detail, distinct atmospheric pathways transport these air masses and trigger floods in the different studied regions. Comparing all the flood reconstructions over the last 250 years aims at tracking these atmospheric pathways and their possible changes over time. Strong similarities in flood frequency are observed from 1750 to 1900 for the western part (Cévennes, Southern French Alps), while no convincing correlation appears between the other records. Around 1900, a drastic change appears with strong similarities between records of the eastern part (Southern Alps, SE French Alps and NW Italian Alps). In particular, the flood frequency largely increased in the Cévennes during the first part of the 20th century, while this period is one of the most 'quiet' in all other records. Hence, these results suggest a reorganization of the flood-prone atmospheric patterns at the onset of the 20th century.

    Full Text Available Average monthly precipitation, the original Palmer Drought Severity Index (PDSI and a recent adaptation to Europe, the Self Calibrated PDSI (scPDSI have been used here to analyse the spatial and temporal evolution of drought conditions in the Mediterranean during the 20th century. Monthly, seasonal and annual trends were computed for the period 1901–2000 and also for the first and second halves of this period. The statistical significance of trends was obtained with a modified version of the Mann-Kendall test that accounts for serial auto-correlation. The results show a clear trend towards drier conditions during the 20th century in most western and central Mediterranean regions, with the exceptions of northwestern Iberia and most of Turkey that reveal an increase of moisture availability. A Generalized Extreme Values (GEV analysis was applied to the maximum and minimum regional values of scPDSI, with results pointing towards a significant decline of absolute extreme values in central areas (Italy and Balkans and a less clear picture emerging in western (Iberia and eastern (Turkey realms.

    The inter-annual variability of the scPDSI index series is shown to be more realistic than the corresponding PDSI version, fitting better the drought episodes sequence and magnitude described in the literature for each sub-region. We assess the decadal and inter-annual variability of the scPDSI for each sub-domain and evaluate the role played by the major teleconnection patterns, and by several sea surface temperature (SST anomalies. The main driver of scPDSI in western and central Mediterranean areas is the winter North Atlantic Oscillation (NAO pattern that is also relevant during the following spring and summer seasons with anti-correlation values below ?0.60. The second most important mode corresponds to the Scandinavian Pattern that is significantly associated to the scPDSI between winter and summer over central Mediterranean (correlation values around 0.50. Finally, the teleconnection and SST analysis has allowed us to calibrate a stepwise regression model, enabling the forecasting of summer drought conditions six months in advance. The final model obtained is capable of reproducing the observed scPDSI time series fairly well, with a correlation coefficient of 0.79 (0.77 after cross-validation and a significant gain over climatology (SSc=59%, while the corresponding result against persistence is more modest (SSp6=11%.

    This paper examines the development of a medical perspective on child sexual abuse during the course of the 20th century and argues that such a perspective has not served the best interests of sexually abused children. An alternate social perspective is outlined, which would appear to have the potential to adequately address the needs of sexually abused children in the 21st century. The paper concludes by arguing that, despite its merits, the social perspective is likely to be of little value...

    With the completion of the Akashi Kaikyo Bridge and the Storebælt East Bridge the development of the suspension bridge technology in the 20th century has manifested itself in two impressive structures. With the present echnology may bridges of similar (and also more modest) dimensions will undoubtedly be built far into the next century. For bridges going beyond the spans of existing bridges it is, however, likely that new concepts will be developed.

    Full Text Available This study examines changes in annual and seasonal mean (minimum and maximum temperatures variations in Jordan during the 20th century. The analyses focus on the time series records at the Amman Airport Meteorological (AAM station. The occurrence of abrupt changes and trends were examined using cumulative sum charts (CUSUM and bootstrapping and the Mann-Kendall rank test. Statistically significant abrupt changes and trends have been detected. Major change points in the mean minimum (night-time and mean maximum (day-time temperatures occurred in 1957 and 1967, respectively. A minor change point in the annual mean maximum temperature also occurred in 1954, which is essential agreement with the detected change in minimum temperature. The analysis showed a significant warming trend after the years 1957 and 1967 for the minimum and maximum temperatures, respectively. The analysis of maximum temperatures shows a significant warming trend after the year 1967 for the summer season with a rate of temperature increase of 0.038°C/year. The analysis of minimum temperatures shows a significant warming trend after the year 1957 for all seasons. Temperature and rainfall data from other stations in the country have been considered and showed similar changes.

    Full Text Available Interdisciplinary frameworks for studying natural hazards and their temporal trends have an important potential in data generation for risk assessment, land use planning, and therefore the sustainable management of resources. This paper focuses on the adjustments required because of the wide variety of scientific fields involved in the reconstruction and characterisation of flood events for the past 1000 years. The aim of this paper is to describe various methodological aspects of the study of flood events in their historical dimension, including the critical evaluation of old documentary and instrumental sources, flood-event classification and hydraulic modelling, and homogeneity and quality control tests. Standardized criteria for flood classification have been defined and applied to the Isère and Drac floods in France, from 1600 to 1950, and to the Ter, the Llobregat and the Segre floods, in Spain, from 1300 to 1980. The analysis on the Drac and Isère data series from 1600 to the present day showed that extraordinary and catastrophic floods were not distributed uniformly in time. However, the largest floods (general catastrophic floods were homogeneously distributed in time within the period 1600–1900. No major flood occurred during the 20th century in these rivers. From 1300 to the present day, no homogeneous behaviour was observed for extraordinary floods in the Spanish rivers. The largest floods were uniformly distributed in time within the period 1300–1900, for the Segre and Ter rivers.

    Nowhere is the problem of understanding the complex linkages between organisms and their environments more apparent than in the science of plants. Today, efforts by scientists to predict and manage the biological consequences of shifting global and regional climates depend on understanding how organisms respond morphologically, physiologically, and behaviorally to changes in their environments. Investigating organismal "adaptability" (or "plasticity") is rarely straightforward, prompting controversy and discourse among and between ecologists and agricultural scientists. Concepts like agro-climatic adaptation, phenotypic plasticity, and genotype-environment interaction (GxE) are key to those debates, and their complex histories have imbued them with assumptions and meanings that are consequential but often opaque. This special section explores the diverse ways in which organismal adaptability has been conceptualized and investigated in the second half of the 20th century, and the multifarious political, economic, environmental, and intellectual contexts in which those conceptions have emerged and evolved. The papers in this section bring together perspectives from the histories of agriculture, population ecology, evolutionary theory, and plant physiology, cutting across Asian, North American, and British contexts. As a whole, this section highlights not only the diversity of meanings of "adaptability" and "plasticity," but also the complex linkages between those meanings, the scientific practices and technologies in which they are embedded, and the ends toward which those practices and technologies are employed.

  16. Brief resume of exploration history in Azerbaijan sector of Caspian sea in 20th century

    International Nuclear Information System (INIS)

    Full text : This article contains information about seismic exploration activities in the shallow water part of Azeri sector of Caspian see in the 20th century. During this time 145 perspective structures had been discovered in Azeri sector of Caspian as a result of the exploration. On some of those perspectives that were prepared for geological prospecting deep-hole exploration drilling was carried out and according to the data acquired, there were 27 oil and gas gas fields discovered at that time. The distinctive feature of these deposits is that the production was conducted by means of special dums, piers, built from the shore and also by deviated wells having there wellhead on the land. After World War 2, due to depletion of the main oil producing region, i.e. Apsheron peninsular, Azerbaijan geologists appealed to exploring new oil bearing deposits in other regions of Azerbaijan. Analyses of the geological and geophysical data reveal that along with the high probability of new deposit detection within already discovered structures, positive results may also be acquired by exploration of non-anticlinal traps and pliocene deposits of the western slope of Caspian sea.

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

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

    Light in the marine environment is a key environmental variable coupling physics to marine biogeochemistry and ecology. Weak light penetration reduces light available for photosynthesis, changing energy fluxes through the marine food web. Based on published and unpublished data, this study shows that the central and southern North Sea has become significantly less clear over the second half of the 20th century. In particular, in the different regions and seasons investigated, the average Secchi depth pre-1950 decreased between 25% and 75% compared to the average Secchi depth post-1950. Consequently, in summer pre-1950, most (74%) of the sea floor in the permanently mixed area off East Anglia was within the photic zone. For the last 25+ years, changes in water clarity were more likely driven by an increase in the concentration of suspended sediments, rather than phytoplankton. We suggest that a combination of causes have contributed to this increase in suspended sediments such as changes in sea-bed communities and in weather patterns, decreased sink of sediments in estuaries, and increased coastal erosion. A predicted future increase in storminess (Beniston et al., 2007; Kovats et al., 2014) could enhance the concentration of suspended sediments in the water column and consequently lead to a further decrease in clarity, with potential impacts on phytoplankton production, CO2 fluxes, and fishery production.

    Early statistical methods focused on pre-data probability statements (i.e., data as random variables) such as P values; these are not really inferences nor are P values evidential. Statistical science clung to these principles throughout much of the 20th century as a wide variety of methods were developed for special cases. Looking back, it is clear that the underlying paradigm (i.e., testing and P values) was weak. As Kuhn (1970) suggests, new paradigms have taken the place of earlier ones: this is a goal of good science. New methods have been developed and older methods extended and these allow proper measures of strength of evidence and multimodel inference. It is time to move forward with sound theory and practice for the difficult practical problems that lie ahead. Given data the useful foundation shifts to post-data probability statements such as model probabilities (Akaike weights) or related quantities such as odds ratios and likelihood intervals. These new methods allow formal inference from multiple models in the a prior set. These quantities are properly evidential. The past century was aimed at finding the "best" model and making inferences from it. The goal in the 21st century is to base inference on all the models weighted by their model probabilities (model averaging). Estimates of precision can include model selection uncertainty leading to variances conditional on the model set. The 21st century will be about the quantification of information, proper measures of evidence, and multi-model inference. Nelder (1999:261) concludes, "The most important task before us in developing statistical science is to demolish the P-value culture, which has taken root to a frightening extent in many areas of both pure and applied science and technology".

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

    Health progress, as measured by the decline in mortality rates and the increase in life expectancy, is usually conceived as related to economic growth, especially in the long run. In this investigation it is shown that economic growth is positively associated with health progress in Sweden throughout the 19th century. However, the relation becomes weaker as time passes and is completely reversed in the second half of the 20th century, when economic growth negatively affects health progress. The effect of the economy on health occurs mostly at lag 0 in the 19th century and is lagged up to 2 years in the 20th century. No evidence is found for economic effects on mortality at greater lags. These findings are shown to be robustly consistent across a variety of statistical procedures, including linear regression, spectral analysis, cross-correlation, and lag regression models. Models using inflation and unemployment as economic indicators reveal similar results. Evidence for reverse effects of health progress on economic growth is weak, and unobservable in the second half of the 20th century. PMID:18249452

  5. Final Scientific Report for "The Interhemispheric Pattern in 20th Century and Future Abrupt Change in Regional Tropical Rainfall"

    2012-10-29

    This is the final scientific report for grant DOE-FG02-08ER64588, "The Interhemispheric Pattern in 20th Century and Future Abrupt Change in Regional Tropical Rainfall."The project investigates the role of the interhemispheric pattern in surface temperature – i.e. the contrast between the northern and southern temperature changes – in driving rapid changes to tropical rainfall changes over the 20th century and future climates. Previous observational and modeling studies have shown that the tropical rainband – the Intertropical Convergence Zone (ITCZ) over marine regions, and the summer monsoonal rainfall over land – are sensitive to the interhemispheric thermal contrast; but that the link between the two has not been applied to interpreting long-term tropical rainfall changes over the 20th century and future.The specific goals of the project were to i) develop dynamical mechanisms to explain the link between the interhemispheric pattern to abrupt changes of West African and Asian monsoonal rainfall; ii) Undertake a formal detection and attribution study on the interhemispheric pattern in 20th century climate; and iii) assess the likelihood of changes to this pattern in the future. In line with these goals, our project has produced the following significant results: 1.We have developed a case that suggests that the well-known abrupt weakening of the West African monsoon in the late 1960s was part of a wider co-ordinated weakening of the West African and Asian monsoons, and driven from an abrupt cooling in the high latitude North Atlantic sea surface temperature at the same time. Our modeling work suggests that the high-latitude North Atlantic cooling is effective in driving monsoonal weakening, through driving a cooling of the Northern hemisphere that is amplified by positive radiative feedbacks. 2.We have shown that anthropogenic sulfate aerosols may have partially contributed to driving a progressively southward displacement of the Atlantic Intertropical Convergence Zone (ITCZ) over the course of the 20th century prior to the 1980s. This is based on our detection and attribution analysis of 20th century simulations done by international modeling groups as part of the Coupled Model Intercomparison Project phase 3 (CMIP3). We repeated the same analysis with the current CMIP5 multimodel simulations, with essentially similar results. 3.Future projections of the global interhemispheric thermal gradient suggest a pronounced trend that well exceeds the 20th century range of behavior. The major cause of this trend is due to anthropogenic greenhouse gas emissions, acting in such a way as to warm the North more than the South. This result is based on our analysis of the CMIP3 and 5 simulations of future scenarios. The underlying suggestion is that tropical rainfall may concentrate more northwards in the future climate, though further research is required to more firmly establish that result.Taken together, our results shows the important role of the interhemispheric thermal gradient in determining tropical rainfall changes in the 20th century and future. Our analysis specifically highlights high-latitude North Atlantic sea surface temperature, and anthropogenic sulfate aerosols, as important drivers of the interhemispheric gradient over the 20th century; and anthropogenic greenhouse gases in the 21st. The PI has written a review paper in order to promote the awareness of the interhemispheric gradient amongst the climate science community.Our project was instrumental in developing the career of a postdoctoral scholar, as well as contributing to the research training of three Ph.D. candidates.

  6. Intergenerational Educational Rank Mobility in 20th Century United States : Differences by Race and Gender

    DEFF Research Database (Denmark)

    Karlson, Kristian Bernt

    BACKGROUND: Studies of educational mobility in the United States report widespread persistence in the association between parental and offspring schooling over most of the 20th century. Despite this apparent persistency, many other studies report substantial improvements in the educational performance of historically disadvantaged groups. To reconcile these diverging trends, I propose examining educational mobility in terms of percentile ranks in the respective schooling distributions of parents and offspring. Using a novel estimator of educational rank, I compare patterns of mobility in the overall schooling distribution both over time and among population groups defined by race and gender.METHODS & DATA: To analyze educational rank mobility, I use quantile transition matrices known from studies on intergenerational income mobility. However, because schooling distributions are quite lumpy, particularly around 12 and 16 years of schooling, percentile ranks of interest may not always be defined among parents or offspring (e.g., the lower or upper quartile may not be given by the data). To deal with this issue, I use a cohort-adjustment that deflates the schooling distribution in proportion to average growth in schooling. The resulting within-cohort distribution of schooling is much smoother than the original distribution and, consequently, it has well-defined percentile ranks. Using about 30,000 parent-offspring pairs in the General Social Surveys, I study quartile-by-quartile matrices for individuals born 1903 through 1980.RESULTS: My analyses yield two key results. First, I find widespread equalization among groups in upward mobility: Among those born before Second World War, Whites are significantly more likely than are Blacks to be upwardly mobile out of the lower quartile of the schooling distribution (about 18 percentage points), but among those born after the War, the gap disappears. Second, I find widespread persistency among groups in downward mobility: Blacks are significantly more likely than are Whites to transition out of the upper quartile of the schooling distribution (about 18 percentage points), and this gap is virtually unchanged between cohorts born over the 20th century. Further analyses show that these differences in mobility with respect to the overall distribution of schooling cannot be explained by differences in the intergenerational transmission of schooling between Blacks and Whites, but rather by the fact that these groups regress to very different means.IMPLICATIONS: My study has at least two implications. First and most importantly, I can compare my estimates to corresponding estimates reported in studies of intergenerational income mobility. These studies show that for cohorts born after the War, Blacks have a much smaller probability of upward income mobility than do Whites. This would suggest that the equalization in upward educational mobility reported in my study has not brought about similar equalization in upward income mobility. Second, my study offers a generalized way to compare nonlinearities and group differences in educational mobility relevant to comparative research across countries.

    The final aim of the climate research is to create correct forecasts of the changing climate for the future. For this reason we have to identify the individual processes which can influence our climate. Knowing the different climate forcing processes and evaluating the effects of their changes can help to achieve this goal. Potential effects of land use changes on the surface albedo and the evapotranspiration are considerable. The land use changes were significant in Hungary in the 20th century according to the database of the Hungarian Central Statistical Office, and different historical maps. Climatic effects of these land cover changes are further evaluated using the MM5 non-hydrostatic dynamical model. The lower boundary conditions are generated for two selected time period, i.e. about 1900 and 2000. The dynamical model has been run with the same detailed meteorological conditions of selected days from 2006 and 2007, but with modified lower boundary conditions. The set of the 26 selected initial conditions represents the whole set of the macrosynoptic situations (Peczely, 1983) for Hungary. In this way, 2x26 forecasts are performed with 48 hours of integration in each case. The effects of land use change under the different weather situations are further weighted by the long-term (1961-1990) mean frequency of the corresponding macrosynoptic types, to assume the climatic effect by these stratified averages. According to the comparisons, climatic effects of the land use changes on the near-surface meteorological variables were not negligible during the surveyed 100 years. In nation-wide average, they caused +0.14 ± 0.5 K temperature rise and 0.17 ± 5 K increase in the dew point depression during the vegetation period, depending on the weather situation. In the selected vertically unstable cases, the land cover differences could significantly perturb the convective precipitation patterns and the area mean as well.

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

  9. Enhanced 20th century heat transfer to the Arctic simulated in the context of climate variations over the last millennium

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

    Full Text Available O presente artigo analisa a representação de personagens deficientes em livros britânicos e norte-americanos do século XIX ao início do século XXI. São analisados tanto os assim chamados clássicos infantis quanto livros fora de edição ou não tão disponíveis. Uma das conclusões é que a representação [...] de personagens deficientes geralmente é mais complexa e variada nos livros mais antigos. Além disso, segundo a visão de muitos autores do século XIX e início do século XX, é necessário aceitar infortúnios como uma forma de obediência a Deus, mas também porque, em última análise, eles são considerados um bem. Portanto, em muitos livros, a deficiência e sua cura, quando ocorre, estão associadas com o caráter. Abstract in english This article examines the treatment of disabled characters in British and North-American children's classics and in books that are out-of-print or less available to children from the 19th century to early 20th century. One of the main findings of this article is that the treatment of disabled charac [...] ters is often more complex and varied in the latter than in the former. Moreover, the prevailing view of many 19th century and some early 20th century authors was that one should submit to misfortunes, both as a form of obedience to God's will, and because these seeming misfortunes are ultimately intended for one's own good. Therefore, in many books, disability, where it occurs, and its cure are associated with character.

  11. Global reconstructed daily storm surge levels from the 20th century reanalysis (1871-2010)

    The study of global patterns of wind and pressure gradients, and more specifically, their effect on the sea level variation (storm surge), is a key issue in the understanding of recent climate changes. The local effect of storm surges on coastal areas (zones particularly vulnerable to climate variability and changes in sea level), is also of great interest in, for instance, flooding risk assessment. Studying the spatial and temporal variability of storm surges from observations is a difficult task to accomplish since observations are not homogeneous in time and scarce in space, and moreover, their temporal coverage is limited. The development of a global storm surge database (DAC, Dynamic Atmospheric Correction by Aviso, Carrère and Lyard, 2003) fulfils the lack of data in terms of spatial coverage, but not regarding time extent since it only includes last couple of decades (1992-2014). In this work, we propose the use of the 20CR ensemble (Compo et al., 2011) which spans from 1871 to 2010 to statistically reconstruct storm surge at a global scale and for a long period of time. Therefore, the temporal and spatial variability of storm surges can be fully studied and with much less effort than performing a dynamical downscaling. The statistical method chosen to carry out the reconstruction is based on multiple linear regression between an atmospheric predictor and the storm surge level at daily scale (Camus et al., 2014). The linear regression model is calibrated and validated using daily mean sea level pressure fields (and gradients) from the ERA-interim reanalysis and daily maxima surges from DAC. The obtained daily database of maximum daily surges has allowed us to estimate global trends at a centennial scale and analyse the effect of the changing climate on storm surges during the 20th century. Hence, this work improves the knowledge on historical storm-surge conditions and provides helpful information to the community concern on marine climate evolution and coastal impacts.

    The record and analysis of statistical information on disaster occurrence, impacts and losses have been made worldwide in recent years. The development of natural disasters databases is crucial for risk management purposes, because it allows improving systems of indicators on disaster risk and vulnerability at national and sub-national scales. During the last century, Portugal was affected by several destructive natural disasters, namely of hydrologic (floods) and geomorphologic (landslides) origin. However, only recently risk prevention and management was assumed to be a national priority by the Portuguese Government. The basic information on past floods and landslides that occurred in Portugal is disperse and incomplete, and this is a shortcoming for the implementation of effective disaster mitigation measures, particularly when it is expectable an increase of frequency, magnitude, dimension and complexity of the hydro-geomorphologic phenomena resulting from climate change. In this work we present a preliminary assessment of hydro-geomorphologic disasters occurred in Portugal during the 20th century, based on the systematic survey of daily national newspapers. We included into a database those floods and landslides that produced, alternatively, dead people, injured people, missing people, evacuated and homeless. A total of 937 hydro-geomorphologic events were registered. In addition to physical and material damages, these events produced economic losses amounting to millions Euros. Our attention will focus on the geographic distribution and the temporal dimension of disastrous floods and landslides occurred in Portugal, and the temporal trends of hydro-geomorphologic disasters will be presented. The preliminary results shown that disastrous floods and landslides have been more frequent on the most populated regions of Portugal: the metropolitan areas of Lisbon and Oporto. In addition, data shows that disastrous hydrologic and geomorphologic phenomena were more frequent from 1940 to 1970, and there is no evidence of a clear increment in time both in the number of disastrous events and the number of associated death people. Finally, we assess the societal risk regarding landslides and floods in Portugal through the construction of F-N curves.

    Full Text Available The keenness and acuity of the agrarian and peasant question, which should be conceived as conscious problem of land scarcity, legal status of peasant social stratum, of peasant agrarians and peasant labourers made political parties at the beginning of the 20th century to work out their visions of crisis situation overcoming in the countryside. The necessity to be armed with own opinion on this matter concerned both Russian and national parties in the Russian Empire. The author suggests reviewing agrarian concepts of various parties as the measure of their referring to either to left wing or liberal political parties. Such concept statement is investigated in frames of historiographic discourse with involvement of original documents, which permits to make sense of the stated issue. The participants of the historiographic dialogue are mostly represented by contemporary scientists, who study the agrarian components of Ukrainian parties platforms at the beginning of the 20th century.

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

    Abstract Background Time trends in infant mortality for the 20th century show a curvilinear pattern that most demographers have assumed to be approximately exponential. Virtually all cross-country comparisons and time series analyses of infant mortality have studied the logarithm of infant mortality to account for the curvilinear time trend. However, there is no evidence that the log transform is the best fit for infant mortality time trends. Methods We use maximum likelihood methods to deter...

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

    Full Text Available The process which created the conditions for the development of
    mass media press in Brazil was consolidated in the first half of the 20th Century with the emergence of newspaper companies based on an industrial form of production, the modernization of the writing style and design, plus the use of photography as a newsy element. There was a strong investment in technology in order to modernize the nation and photography, as a technical image par excellence, started to portray the acceleration of the passage of time that was accentuated by the 1890’s. In the beginning of the 20th century a new technological trend occurred mediated by the photographic apparatus and diffused through the newspaper and illustrated magazines pages that were multiplying in the nation’s capital, Rio de Janeiro1. The press used photography and a series of technological artifacts to acquire the status of a modern entity and multiply the number of readers, changing its forms of production and its auto-referential discourse, starting to be more and more the icon of modernity. The technologies capable of giving a wider dimension to the concept of time and space were decisive in shaping the new symbolic world which emerged since the turn of the century. The world got closer and more visible, the perception of the “other” changed gradually and temporality took on a new dimension. This article traces a panorama of the use of photography by the main newspapers published in the capital of Brazil in the first half of the 20th century, seeking in photography the reflection of the modernizing process that Brazilian society desired and underwent.

    2011-06-01

    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.

    Adriatic and Black Sea are semi-enclosed basins characterized by densely populated coasts, industrial compounds and a rich cultural and historical heritage. It appears to be crucial, for the management and the protection of their coastlines, to understand how much they will be impacted by the global sea level (SL) rise, projected by the end of this century. The aim of this work is to develop a method that allows to estimate to which extent the SL of the two basins will depart from the mean global level. The future evolution of global sea level is not a meaningful indicator at this regional scale and past deviations, due to local factors of the Adriatic and Black Sea levels from the global one, have been observed. The Adriatic Sea is the basin of the Mediterranean Sea best covered by past SL observations. In fact, for the Adriatic Sea is possible to obtain, by statistical method based on PCA and Least square Method, a seamless and long time series (from 1900 to 2009) using records of 7 mareographic stations located along the Italian and Croatian coasts (from PSMSL database). Satellite data of SL are available for the whole Mediterranean from 1993 to 2012 and they show a very high correlation (rho > 0.9) with Adriatic time series based on mareographic records. The SL time series of the 20th century in the Black Sea is computed using data of 4 stations, which are available in the PSMSL (Permanent Service for Mean Sea Level) archive, located on the north-east coast. This time series shows a lower correlation (rho about 0.5) with satellite data than in the case of Adriatic Sea. Further it shows a higher interannual variability. All the time series are considered after the subtraction of the Inverse Barometer (IB) effect. A statistical approach, based on a multivariate linear regression model, is used to investigate the link between SL anomaly, computed as the difference between the regional SL and global SL, and three large scale climate variables (sea level pressure, air temperature and precipitation). The linear model at a monthly scale provides a good reconstruction of the past variability in the case of Adriatic sea, but presenting substantial differences in the reconstruction skill between cold and warm seasons. Reconstruction is substantially worse for Black Sea. Always the main factor reproducing the signal variability is represented by the mean sea level pressure. The model forced by predictors extracted from CMIP5 multi-model simulations, finally provides the projections of SL anomaly until 2100. This study is part of the activities of RISES-AM project (FP7-EU-603396).

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

    2015-07-01

    During the 19th century, numerous figures, with different qualifications, claimed to practice orthopedics: doctors, surgeons, inventors of equipment and instruments, and other empiricists. They performed certain types of techniques, massages, surgical operationsand/or fitted prostheses. The polysemous notion of orthopedics had created conflicts of interest that would reach their height at the end of the 19th century. The integration of orthopedics into the training at the university level enhanced its proximity to surgery, a discipline that has dominated the so-called modern medicine. During the 20th century, various medical branches defend the legitimacy of certain orthopedic practices, thereby threating to a degree the title itself of this specialization. By examining the challenges that have shaped the history of orthopedics in Switzerland, this article also seeks to shed light on the strategies that were implemented in adopting a medical and technical discipline within a transforming society.

    2011-09-01

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

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

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

    Geodiversity is the natural and cultural range of geological, geomorphological and soil features. We analysed the large database of 19th and early 20th century paintings of Simonis and Buunk (www.Simonis-Buunk.com) to track changes in the geodiversity of Dutch peatlands since pre-photographic times. Peat dominated in two of the eight main landscapes of the Netherlands: the Lowland peats in the Holocene west and the Highland peats in the sandy Pleistocene eastern parts. Painters were mainly attracted by the lowland peats. Since more than thousand years, peat plays a major role in Dutch military security, economy, ecology and cultural life. Natural variety and cultural use resulted in a geodiversity that is unique in Europe. There are more than 100 place names with 'veen' (= peat), and surnames with 'veen' are common. Proof of the exploitation of peat for salt and fuel exists from the Roman times onwards. In the 9th century, peatlands were drained and reclaimed for growing wheat. Already in the 11th century, it was necessary to build dikes to prevent flooding, to control waterlevels to avoid further oxidation, and to convert landuse to grassland. But subsidence continued, and in the 14th century windmills were needed to drain the lands and pump the water out. In the 16th century industrial peat exploitation fuelled the rise of industries and cities. All this draining and digging caused the peat surface to shrink. The few remaining living peats are conserved by nature organisations. Geodiversity and landscape paintings In the peat landscapes, popular painting motives were high water levels, the grasslands of the 'Green Heart', the winding streams and remaining lakes. The paintings of landscapes where peat had been removed, show watermanagement adaptations: wind mills, different water levels, canals made for the transport of fuel, bridges, tow paths and the 'plassen', i.e. the lakes left after peat exploitation. The droogmakerijen (reclaimed lakes), now 2 to 5 m below sealevel, were less inspiring. Examples of geodiversity changes illustrated by the landscape paintings • Peat extraction stopped • Land use changed e.g. the deforestation of the 'Bovenlanden' • Erosion by waves and boats caused the collapse of peat islands in the artificial lakes • Peat polders of the Green Heart were sacrificed for building projects • 90% of the original wind mills were replaced by electrical and motor pumps • Horse traction was replaced by motor vehicles, which made tow paths and high wooden bridges redundant. • Dam burst risk increased and skating scenes disappeared with climate change, References Jungerius, P.D., 2010.

  16. Morphologic changes in the Paraná River channel (Argentina) in the light of the climate variability during the 20th century

    2005-09-01

    Recent studies regarding the climate variability in South America during the 20th century, revealed the existence of climate cycles that influenced the hydrologic conditions in the Paraná River basin, one of the largest in the continent. How that variability affected the channel morphology of this river in its middle reach is quantitatively analyzed in this paper. The link between climate, hydrology and channel morphology is obtained through the computation of effective discharge. This discharge implicitly synthesizes the point hydrologic and bed sediment transport changes in an alluvial stream during a relatively long period. The results were obtained studying, with increasing detail, two channel reaches 373 km and 25 km long, respectively. The analysis involved the processing of more than 180 bathymetric charts, satellite images and hydraulic and sedimentologic data recorded in the Paraná River since the very beginning of the 20th century. A rather detailed description of the treatment made with this information is given in the paper. It is shown that three periods of different effective discharges fairly well correlated with reported climatic fluctuations occurred during the last 100 years, i.e. two periods of high discharges (at the century beginning and from 1970 till present) and another of relatively low discharges between 1930 and 1970. Morphologic parameters of the main channel, such as mean width, thalweg sinuosity, braided index and aspect ratio, increased or decreased in correspondence with those variations. In transitional channels (between meandering and braided) like the Paraná River, careful study of the thalweg behavior is a key issue, if a proper approach to the dynamic of morphologic processes operating on the whole channel is intended. Finally, on the basis of theoretical (extreme hypotheses approach) and empirical results, it is suggested that the Paraná River main channel would not be adjusted to the present high values of effective discharge. Thus, larger erosion of banks (channel widening) and increases in the other cited morphologic characteristics will occur if those values persist.

  20. Effects of The NAO/ao Fluctuations Upon Precipitation Over Sardinia In The 20th Century.

    Science.gov (United States)

    Delitala, A.

    The effects at regional scale of decadal fluctuation of the NAO/AO on the 20th cen- tury precipitation over Sardinia will be analyzed. Decadal variations of precipitation will initially be described, by use of the Standardized Anomaly Index (Katz &Glantz, 1986) based on two indicators: the cumulated precipitation (the classical approach) and the number of rainy days. A clear decreasing trend in the last two deacdes, statis- tically significant at the 1% level, will be highlighted. A short survey of connections with MSLP and 500hPA Geopotential Height fields will be used to give an overview of dependence of Sardinia (regional) precipitation on synoptic-scale and planetary scale features. In the following part, three different paradigms of the NAO/AO will be used: the classical two point obscillation, the PCA analysis of MSLP (Thompson &Wallace, 1998) and the centers of action approach (Machel et al., 1998). The results of the anal- ysis of the effects of NAO/AO (described in the former three ways) on precipitation will enable to discuss how such a teleconnection influences regional precipitation on this part of the Mediterranean. Statistical significance of each result will be provided during the presentation. Katz, R., Glantz, M., 1986. "Anatomy of a Rainfall Index". Mon. Wea. Rev., 114, 764-771.

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

    Energy Technology Data Exchange (ETDEWEB)

    2005-11-01

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

    During the first half of the 20th century numerous drugs, foodstuffs and cosmetics were brought on the market, whose supposed effects were explained with their weak radioactivity. Their subtle radiation was believed to stimulate the vital forces of the body, thus leading to recovery from illness, or to an improvement in beauty and to rejuvenation. Among others, bath and drinking waters enriched with radioactive materials were advertised for this purpose. The then known radioactive medicines included preparations of healing earth, the so-called Salus-Oil, the TRUW preparations, and "Radithor", which was popular in the United States. There were also radioactive foodstuffs (butter, chocolate, rusk) and cosmetics. This mild radiotherapy may be characterised as a form of bio-dynamistic healing. PMID:16382691

    This article aims to reconstruct the elements of continuity and/or discontinuity in Sante De Sanctis' (1862-1935) contributions in the scientific understanding of sleep and dreaming as compared to the scientific research of his time. An Italian psychologist and psychiatrist, De Sanctis, in his work conducted between the 19th and 20th centuries, has framed the study of dreams using multi-methodology. In addition, De Sanctis experimentally established the correspondence between the deep and desynchronization phases of sleep with respect to dreaming. In this context, De Sanctis' subjects described the periodicity of sleep and consciousness, influencing the explanations of the themes that modern sleep research has, after decades, systematically studied. We demonstrate that De Sanctis' work has been underestimated, and in our opinion, deserves to be reconsidered as a source of the psychophysiological explanation of dreams and sleep. Finally, we present a graphical representation of De Sanctis' psycho- and neurophysiological model of dreaming. PMID:25533542

  4. Dating of ivory from 20th century by determination of 14C by the direct absorption method

    International Nuclear Information System (INIS)

    We aim to date ivory samples by determination of the concentration of 14C in the sample. However, such data do not always represent unambiguous evidence. In these cases other nuclides have to be additionally analyzed which causes additional costs. To make the dating method still affordable, the direct CO2 absorption method for analyzing 14C was tested. Results show that this method has a precision of about 4.0% (95% confidence level) which is good enough for this purpose. - Highlights: ? Dating ivory samples from the 20th century. ? Using direct CO2 absorption as an easy method with adequate performance for 14C determination. ? 90Sr and 228Th/232Th determination provides additional information when the data of 14C represent ambiguous evidence.

It suggests that an autoimmune interference at the apoB-LDL interface could explain both hypercholesterolemia and inflammation (through interference with the cellular metabolism of arachidonic acid. Autoimmune inflammation, then, would explain the 1950s-60s acute coronary events (coronary thrombosis upon influenza re-infection and the respiratory failure seen among young adults in 1918. This hypothesis also argues that the lethality of the 1918 pandemic may have not depended so much on the 1918 virus as on an immune vulnerability to it, possibly resulting from an earlier priming of cohorts born around 1890 by the 1890 influenza pandemic virus.

    1993-01-01

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

  8. Using atmospheric CO2 data to assess a simplified carbon-climate simulation for the 20th century

    International Nuclear Information System (INIS)

    The CSIRO biosphere model has been coupled to an atmosphere model and a simulation has been performed for the 20th century. Both biosphere and atmosphere are forced with global CO2 concentration and the atmosphere is also forced with prescribed sea surface temperatures. The simulation follows the C4MIP Phase 1 protocol. We assess the model simulation using atmospheric CO2 data. Mauna Loa growth rate is well simulated from 1980 but overestimated before that time. The interannual variations in growth rate are reasonably reproduced. Seasonal cycles are underestimated in northern mid-latitudes and are out of phase in the southern hemisphere. The north-south gradient of annual mean CO2 is substantially overestimated due to a northern hemisphere net biosphere source and a southern tropical sink. Diurnal cycles at three northern hemisphere locations are larger than observed in many months, most likely due to larger respiration than observed

  9. Evidence for 20th century climate warming and wetland drying in the North American Prairie Pothole Region

    2013-01-01

    The Prairie Pothole Region (PPR) of North America is a globally important resource that provides abundant and valuable ecosystem goods and services in the form of biodiversity, groundwater recharge, water purification, flood attenuation, and water and forage for agriculture. Numerous studies have found these wetlands, which number in the millions, to be highly sensitive to climate variability. Here, we compare wetland conditions between two 30-year periods (1946–1975; 1976–2005) using a hindcast simulation approach to determine if recent climate warming in the region has already resulted in changes in wetland condition. Simulations using the WETLANDSCAPE model show that 20th century climate change may have been sufficient to have a significant impact on wetland cover cycling. Modeled wetlands in the PPR's western Canadian prairies show the most dramatic effects: a recent trend toward shorter hydroperiods and less dynamic vegetation cycles, which already may have reduced the productivity of hundreds of wetland-dependent species.

    More than 30 Chinese students went to Great Britain to study physics during the first half of the 20th century. They were concentrated in London University (13), Cambridge University (9), Edinburgh University (5) and Manchester University (3) and so on. All these students returned to China after finishing their study and most of them later became excellent physicists. They contributed to the development of physics in China. Based on newly discovered primary materials concerning these Chinese physicists, I examine their study in UK and subsequent accomplishments after their return to China. I will then analyze these British-trained Chinese physicists and compare them with those studying in Japan and America. I would argue that Chinese physicists educated in Britain have high degree of specialization as a whole and formed unique style. They made certain unique contributions to Chinese physics development.

  11. Precipitation changes in wet and dry seasons over the 20th century simulated by two versions of the FGOALS model

    2015-06-01

    Seasonal precipitation changes over the globe during the 20th century simulated by two versions of the Flexible Global Ocean-Atmosphere-Land System (FGOALS) model are assessed. The two model versions differ in terms of their AGCM component, but the remaining parts of the system are almost identical. Both models reasonably reproduce the mean-state features of the timings of the wet and dry seasons and related precipitation amounts, with pattern correlation coefficients of 0.65-0.84 with observations. Globally averaged seasonal precipitation changes are analyzed. The results show that wet seasons get wetter and the annual range (precipitation difference between wet and dry seasons) increases during the 20th century in the two models, with positive trends covering most parts of the globe, which is consistent with observations. However, both models show a moistening dry season, which is opposite to observations. Analysis of the globally averaged moisture budget in the historical climate simulations of the two models shows little change in the horizontal moisture advection in both the wet and dry seasons. The globally averaged seasonal precipitation changes are mainly dominated by the changes in evaporation and vertical moisture advection. Evaporation and vertical moisture advection combine to make wet seasons wetter and enhance the annual range. In the dry season, the opposite change of evaporation and vertical moisture advection leads to an insignificant change in precipitation. Vertical moisture advection is the most important term that determines the changes in precipitation, wherein the thermodynamic component is dominant and the dynamic component tends to offset the effect of the thermodynamic component.

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

    In this thesis mainly anthropometric indicators are used to investigate several aspects of living standards and inequality in global and historical perspective. Chapter two uses anthropometric information as an indicator for human health and welfare in 156 countries spanning the period 1810-1989. The findings suggest that regional height levels around the world were fairly uniform throughout most of the 19th century, with two exceptions: above-average levels in Anglo-Saxon settlement regions ...

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

  5. The distribution of an illustrated timeline wall chart and teacher's guide of 20th century physics

    Energy Technology Data Exchange (ETDEWEB)

    Schwartz, Brian

    2000-12-26

    The American Physical Society's part of its centennial celebration in March of 1999 decided to develop a timeline wall chart on the history of 20th century physics. This resulted in eleven consecutive posters, which when mounted side by side, create a 23-foot mural. The timeline exhibits and describes the millstones of physics in images and words. The timeline functions as a chronology, a work of art, a permanent open textbook, and a gigantic photo album covering a hundred years in the life of the community of physicists and the existence of the American Physical Society. Each of the eleven posters begins with a brief essay that places a major scientific achievement of the decade in its historical context. Large portraits of the essays' subjects include youthful photographs of Marie Curie, Albert Einstein, and Richard Feynman among others, to help put a face on science. Below the essays, a total of over 130 individual discoveries and inventions, explained in dated text boxes with accompanying images, form the backbone of the timeline. For ease of comprehension, this wealth of material is organized into five color-coded story lines the stretch horizontally across the hundred years of the 20th century. The five story lines are: Cosmic Scale, relate the story of astrophysics and cosmology; Human Scale, refers to the physics of the more familiar distances from the global to the microscopic; Atomic Scale, focuses on the submicroscopic world of atoms, nuclei and quarks; Living World, chronicles the interaction of physics with biology and medicine; Technology, traces the applications of physic to everyday living. Woven into the bottom border of the timeline are period images of significant works of art, architecture, and technological artifacts such as telephones, automobiles, aircraft, computers, and appliances. The last poster, covering the years since 1995, differs from the others. Its essay concerns the prospect for physics into the next century, and is illustrated with pictures of promising award winning high school students who, it is hoped, will be the leading researchers of physics in the decades ahead. Appropriately the last entries in the timeline are not achievements but open questions to be answered in the future.

  6. Changing climatic and anthropogenic influences on the Bermejo wetland, through archival documents - Mendoza, Argentina, 16th-20th centuries

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

    Full Text Available The changes which took place in the balance of power in Europe in the last thirty years of the 19th century, together with the process of colonial expansion and partition, led Spanish geographers to see the need to combine the territorial projects and interests of Spain and Portugal with the aim of defending what remained of their colonial empires, coveted by English-speaking countries. This gave new life to a school of thought known as "Iberismo", which now extended to include France in the formula of a "triple alliance of the South" based on the common interests of Latin countries. The failure of both attempts at rapprochement gave rise to these ideas being transferred, by the beginning of the 20th century, to the Spanish-speaking countries of America. Iberismo was to become "Hispano-Americanismo", and the defence of strategic and material interests was to begin with a reaffirmation of the moral and spiritual qualities of peoples sharing common roots and a common language. Ideas and arguments along these lines were then developed on both sides of the Atlantic, crossing boundaries into other spheres of intellectual activity.

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

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

    Full Text Available The Contuinity and Discontinuity. The Question of Territorialism and Double Identity from the Perspective of 20th Century MacedoniaThe sense of territorial identity gains force whenever political means of solving the Macedonian Question, a repugnant legacy of the Eastern issue, become scarce. This attitude is reflected in the articles published by the representatives of the Macedonian diaspora in journals of its different centres. Due to space constraints I decided to present only (and at least the views of Krste Misirkov, a very complex figure indeed, who in contemporary Macedonia belongs to the undisputable national pantheon. His opinions on the Macedonian Question were far from explicit and his statements delivered at different stages of his life do not fit into a cohesive whole as the national purists would want it. However, it is difficult to imagine a better mirror for “Macedonian matters” in the 20th century and a more comprehensive picture of the twisted paths that the Macedonian Slavs took to reach the concept of ‘Macedonian’ understood as an ethnos, not only in its territorial aspect.A bond with the territory has never disappeared from Macedonian self-perception. Only the constant presence of territorial identity explains the assimilation of the ancient heritage, which is in fact heritage of a territory, into the Macedonian national canon. It is further confirmed by the most recent Macedonian history textbooks for high school students where the ancient tradition is treated as a part of their own heritage. While the bond with the territory is still an integral part of the Macedonian elite’s consciousness, the question of double identity remains less obvious. In Misirkov’s time double identity, expressed through various ethnic configurations, on the one hand shaped Macedonian self-identity and on the other proved the distinctiveness of a ‘Macedonian’ at that time (i.e. in the first half of the 20th century from a ‘Serb’ in Serbia proper and a ‘Bulgarian’ in Bulgaria proper, thus creating favourable conditions for the emergence of separatist understanding of Macedonianness, allowing even non-Slavs to be Macedonians. Macedonianness began to be founded on Slavicness relatively late and this dependence was propagated quite naturally mainly by Slavophile circles (the circle of Nace Dimov and by the communists in the 1920’s and 1930’s. However, in the first half of the 20th century there still existed alternatives, such as, for instance, the above-described project of Krste Misirkov. The most evident connection between the term ‘Macedonian’ and Slavicness crystallised in Tito’s post-war Macedonia, de facto undermining the notion of double identity in the sense in which it had functioned in the first half of the 20th century.Ci?g?o?? i jej brak.

  12. Changes of mean relative sea level around Canada in the 20th and 21st centuries

    Trends in regional mean sea levels can be substantially different from the global mean trend. Here, we first use tide-gauge data and satellite altimetry measurements to examine trends in the mean relative sea level (MRSL) for the coasts of Canada in the past century. We then combine model output and satellite observations to provide sea level projections in the 21st century. The MRSL trend based on historical tide-gauge data shows large regional variations, from 3 mm/yr (above the global mean MRSL rise rate 0f 1.7 mm/yr) along the southeast Atlantic coast, close to or below the global mean along the Pacific coast and Arctic, to -9 mm/yr in the northeast centred near Hudson Bay. This significant spatial contrast can largely be attributed to the vertical land motion. The combination of altimeter-measured sea level change with Global Positioning System (GPS) data can approximately account for tide-gauge measurements at most stations over 1993-2011. When the GPS data are used the projected MRSL change between 1980-1999 and 2090-2099 under a medium high climate change emission scenario (A2) ranges from -50 cm in the northeast to 75 cm in the southeast. Along the Beaufort Sea, the MRSL rise is up to 70 cm. The MRSL change in the Pacific coast varies from -15 to 50 cm. The ocean steric and dynamical effect contributes to the MRSL rise along the Canadian coasts, and is dominant in the southeast. The land-ice (glaciers and ice sheets) melt contributes 10-20 cm to the MRSL rise, except in the northeast. The effect of the vertical land uplift is large in the northeast centered near Hudson Bay, significantly reducing the MRSL rise. The land-ice melt also causes the MRSL to fall in the northeast. The projected MRSL change under a high emission scenario (RCP 8.5) has a spatial pattern similar overall to that under A2, with a slightly bigger rise of 7 cm on average and some notable differences at specific sites.

  13. The danish vocational education and training system in the 19th and 20th century

    Directory of Open Access Journals (Sweden)

    Ida JUUL

    2015-04-01

    Full Text Available This article analyzes the development of Vocational Education and Training (VET in Denmark. It traces the characteristics of the Danish VET system of today back to the late 19th century. It was during this period that the control of the guilds over apprentices was replaced by a free market model and later by legislative regulations. Parallel to this development, the masters began to engage in the liberal education of their apprentices. Later, this involvement was institutionalized by giving the social partners a central role, alongside the Ministry of Education, in the management of the VET system. With the introduction of new VET legislation in 1956, the dual system was introduced, combining workplace training with practical and theoretical school-based training. Although workplace training today comprises 2/3 of vocational education and training, the introduction of daytime school-based training signaled the beginning of a process in which the VET system became more and more integrated in the general educational policy of the country. The article illustrates how this has forced the VET system to adapt to changing political strategies in ways which do not necessarily reflect problems inherent to the VET system itself. The strategy of education for all is considered as an example.

  14. 20th-century glacier recession and regional hydroclimatic changes in northwestern Patagonia

    This paper documents the occurrence of significant glacier and hydroclimatic changes in northwestern Patagonia during the past century. Drastic, widespread glacier recession is documented by repeat photography of some of the earliest glacier images from southern South America. Linear trends in regionally-averaged annual and seasonal temperature and precipitation records indicate significant warming and decreasing precipitation over the 1912-2002 interval. A climatic index is developed, based on winter precipitation and summer temperature records, that mimics glacier mass balance relationships and shows a strong negative trend which agrees with the drastic glacier recession shown by the photographic comparisons. Short positive periods of this climatic index broadly correspond with known evidence of glacier advances in the region. Regionally-averaged mean annual streamflow records east of the mountains were used in an independent verification check of the climatic series used in this study. This regional runoff record shows a strong negative trend, remarkable similarities with the climatic index, and highly significant positive (negative) correlations with the regional precipitation (temperature) series. This highlights the existence of a strong, regionally coherent hydroclimatic signal across this region and supports the utility of these records as environmental indicators for northwestern Patagonia between ca. 38° and 45°S. Given the significant socio-economic importance of rivers and glaciers in this area, further research is needed to evaluate the full range of natural hydroclimate variability and improve understanding of potential impacts of the future warmer and drier climates projected for this region.

    2010-12-01

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

    La segunda mitad del siglo XIX es un periodo caracterizado por una muy importante presencia social de la ciencia, que incluso llega a permear las clases populares. Las teorías evolucionistas y algunas figuras como la del propio Darwin aparecen así en ámbitos en principio alejados de los de la creación científica. La utilización de conceptos y leyes de origen biológico para el diagnóstico y la práctica política frente a determinadas realidades sociales problemáticas, como la delincuencia o la pobreza, dio lugar al surgimiento de teorías y escuelas intelectuales que hicieron valer los principios evolucionistas de aplicación biológica al análisis de complejas realidades de desigualdad sociocultural. La atracción por la diferencia y por el método científico, junto a la posibilidad de observación de situaciones de pobreza y desigualdad social que el desarrollo industrial y la modernidad ponían delante de los escritores, provocaron un interés literario por la degeneración, física y cultural, de la humanidad que confluía con el de naturalistas y biólogos.

  16. TOPOGRAPHIC MAPPING SUPPORT IN THE SOUTH AFRICAN MILITARY DURING THE 20TH CENTURY

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

    Full Text Available This paper analyzes the process of natural growth movements of the City of Belgrade in the second half of the 20th and beginning of the 21st centuries. The time level of the analysis was determined by the available data on vital statistics (1961-2005, while the spatial level was determined by the administrative distribution of the City into districts during the 2002 census. It has been established that the natural growth rates for the City of Belgrade were stable until the beginning of the 1980s, though with small oscillations. Then a decrease began until 1992, when the number of deaths exceeded the number of births, with a tendency of negative growth. From then on, the population of Belgrade increased in the last decade of the 20th and beginning of the 21st centuries, only due to the migration component. Although the increase of Belgrade population has never mainly depended on natural growth, it was concluded in the paper that the effects of the ceased natural replacement would yet be shown.

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

    The consequence of elevated ocean temperatures on commercial fish stocks is addressed using time series of commercial landings (1906–2004) and juvenile survey catch data (1904–2006) collected around Denmark. We analyze (i) whether warm?water sole (Solea solea) has increased relative to Boreal plaice (Pleuronectes platessa) and (ii) whether two related warm?water species (turbot, Psetta maxima and brill, Scophthalmus rhombus) show similar responses to increasing temperature or, alternatively, whether turbot (which has a broader juvenile diet) has been favored. Since the early 1980s, both sole and turbot have constituted an increasing part of the commercial landings and survey catches, as compared with plaice and brill, respectively. These changes in species composition were linked to sea surface temperatures, Northern Hemisphere temperature anomalies (NHA) and the North Atlantic Oscillation. NHA was closely related and explained 43% of the observed variation in sole survey catches relative to the plaice catches and almost 38% of the observed variation in the sole landings relative to the plaice landings. For the less common species, turbot and brill, none of the global change indicators explained more than 15% of the variation, although all showed a positive relationship. Survey catch per unit effort increased significantly for both sole and turbot around the early 1980s, whereas catch per unit effort for plaice and brill remained constant. The results indicate that the abundance of warm?water species is likely to increase with increasing temperature but also that species with similar life histories might react differently according to degree of specialization.

    Full Text Available El siglo XX ha sido uno de los períodos de la Historia más intensos y Convulsivos que le ha tocado vivir a la humanidad. Siglo de paradojas y de contrastes, se inició con optimismo, fue testigo del apocalipsis de dos guerras mundiales y terminó con un progreso científico inimaginable que nos condujo [...] a una nueva civilización, que aún no podemos intuir. En él ocurrieron grandes acontecimientos que moldearon nuestro tiempo y proyectaron sus resultados hacia un futuro inmediato. Unos fueron providenciales para entender la vida del hombre, combatir las enfermedades y prolongar la vida y otros de innegable importancia social para la humanidad. Unos saberes se fundamentaron en otros. La filosofía se adentro en la matemática, como la ciencia en la filosofía, mientras la política y la economía ejercían tan decisivo influjo en nuestro modo de sentir y de vivir, que la cultura y la sociedad se conmovieron hasta sus cimientos. En esa centuria, se gestó además, la mayor revolución tecnológica de todos los tiempos, tan trascendental como inimaginable, que con el alunizaje pusieron al hombre en el camino hacia las estrellas y con ella se creó la sociedad de la información, cuyo máximo símbolo: internet, emergió como un nuevo demiurgo. Sin embargo ha sido el siglo XX hasta ahora, con todo su infortunio y esplendor, paradojas y contrastes, creación y destrucción, el más trascendental de toda la historia y lega al futuro un horizonte promisor en la búsqueda de un renovado significado de vida y un anhelo de convivencia pacífica para toda la humanidad. Abstract in english The 20th century has been one of the most intense and convulsive periods in the History of humanity. A century of paradoxes and contrasts, it began with optimism, it witnessed the apocalypse of two world wars, and finished with unimaginable scientific progress that gave us a new civilization that we [...] cannot yet grasp. In this century, significant events happened that shaped our time and projected their results toward an immediate future. Some of these were providential in understanding man 's life, fighting against illnesses and prolonging life, and others were of undeniable social importance for humanity. Some knowledge was based on the work of others. Philosophy was embedded in mathematics, as was science in philosophy, while politics and the economy exercised so decisive an influence in our way of feeling and living that culture and society were affected to the core. Within that century the biggest technological revolution of all the time was also created, as transcendent as it was unimaginable, which put mankind on the road to the stars with the moon landing and in the process created the information society whose signature symbol, the internet, emerged as a new demiurge. However, the 20th century, with all its misfortune and splendor, paradoxes and contrasts, creation and destruction, was the most transcendent in the whole of history and it bequeaths to the future a promising horizon in the search for a renovated meaning of life and a yearning for peaceful coexistence for the whole humanity.

  4. Evaluating 20th century warming trends with modern Porites corals from the western Indian Ocean

    Recent studies suggest that instrumental records of sea surface temperature (SST) are unreliable prior to 1965 due to changes in the measurement procedures. Thompson et al. (2008) identified an artificial cool bias of up to 0.3Ë? C in global mean SSTs between 1945 and the mid-1960s. Geochemical parameters in skeletons of massive corals can be used to infer past changes in climate on seasonal to centennial time scales. The Sr/Ca ratio of coral aragonite is a widely used tool for deriving high-resolution proxy records of past sea surface temperatures. Application of the Sr/Ca paleothermometer relies on the assumption that coral Sr/Ca varies predictably with temperature and that seawater Sr/Ca is invariant on millennial timescales due to the long residence time of Sr and Ca in the ocean. In contrast, the oxygen isotope ratios (^18O) of coral aragonite vary in response to temperature and changes in the ^18O of seawater, the latter depending on the freshwater balance. Thus, coral ^18O may be used as a record of past sea surface temperatures only at sites were ^18O seawater variations are negligible. SST in the western tropical Indian Ocean closely follows global mean temperature trends (Funk et al., 2008). Here we present a set of Porites coral Sr/Ca and/or oxygen isotope records from the tropical Indian Ocean covering the past 120-336 years (Seychelles, Chagos Archipelago). We computed a composite sea surface temperature record for the Western Indian Ocean using ^18O (Seychelles) and Sr/Ca (Chagos). This record clearly follows instrumental SST trends in the Western tropical Indian Ocean, except in the 1945-1965 interval, were instrumental SST data show a pronounced cooling not evident in the coral proxy index (the linear correlation coefficient between the coral index and instrumental SST is r=0.86 if we omit the most problematic time period from 1945 to 1960). However, the coral index follows the global land surface air temperature trend, which is free of systematic biases due to changes in the measurement technique. We therefore conclude that the cooling of the tropical Indian Ocean indicated by instrumental SST is an artifact that may result from changes in the SST measurement techniques, as suggested by Thompson et al., 2008). Our results will have important implications for the investigation of large-scale teleconnections in the oceans (for example, the apparent shift in the Indian Ocean SSTs around 1945 has been related to a regime change in the North Pacific Ocean).

  5. Surgical pathology in the 20th century at the Mount Sinai Hospital, New York.

    How did the education of surgical pathology, and pathology in general, differ at Mount Sinai? Passing the examination of the American Board of Pathology was never the focus of the department. Learning criteria or quoting references was de-emphasized, but mastery of macroscopic pathology was required, supported in both word and action by two brilliant surgical pathologists, Otani and Kaneko, and by two extraordinary medical pathologists, Klemperer and Popper. Meticulous microscopy emphasized pattern rather than reliance on lists of discrete features. Otani developed a regular "problem case" meeting for a community of pathologists, made up of alumni and other interested pathologists, as well as active department members. These monthly sessions provided the highest level of "continuing medical education." Otani and Kaneko unequivocally believed in learning from cases, and Mount Sinai residents were fortunate both in the one-to-one teaching and in the wealth of material, in all systems, that came to surgical pathology. Outstanding pathologists who came from Mount Sinai settled throughout the country and provided the highest level of diagnoses, but, with the exception of Bernard Wagner, Emanuel Rubin, Fiorenzo Paronetto, Richard Horowitz, Michael Gerber, Marc Rosenblum, Bruce Wenig, Jaishree Jagirdar, Swan Thung, Cesar Moran, Hideko Kamino, Philip LeBoit, Alberto Marchevsky, and others, there were relatively few academic leaders. Otani and Kaneko did not have national reputations. Klemperer, although world renowned, was relatively unassuming, and his disciples numbered almost as many nonpathologists as pathologists. Popper did establish a major center for liver pathology, with students coming from around the world, but did not particularly promote general surgical pathology. Can the Mount Sinai approach still be applied? The decline in the numbers of autopsies performed, the demands for rapid turnaround time, the de-emphasis of gross pathology as newer technologies (eg, immunohistochemistry, cytogenetics, molecular pathology) gain place, the increasing tendency to select investigators, including basic scientists, as teaching department chairs and the financial constraints requiring increasing use of nonphysician workers all speak to the relegation of the Otani-Kaneko era to history. Is this a loss to Pathology? It is certainly a style of practice that has been lost. However, there is no reason to bemoan the state of Pathology in the beginning years of the 21st century. Pathology practice is outstanding at many medical centers throughout the world, including at Mount Sinai under the very able and creative leadership of Alan Schiller, who has presided over great enhancements of the department in both anatomic and clinical pathology, including significant advances in the study of diseases by molecular methods. Surgical Pathology at Mount Sinai has been led by James Strauchen, a renowned hematopathologist recruited by Schiller's predecessor, Jerome Kleinerman, and is currently directed by Ira Bleiweiss, a student of Kaneko. Other techniques and technologies have, to a degree, compensated for some of the changes since the Otani-Kaneko years and it is almost certain that advances in molecular pathology will allow for increasing sophistication in establishing diagnoses, and likely even grading and staging, probably even on blood, rather than tissue, samples. The science of Pathology will advance, as the art declines. Those who learned at Mount Sinai during the Otani-Kaneko years will, however, very likely tell you that they were privileged to have learned Pathology there and, especially, to have learned a distinct philosophy of Pathology under the guidance of caring, thoughtful, and especially gifted pathologists.

    Full Text Available The article dwells on the problem of Rakhmaninov’s art, style and poetics influence on the process of formation and development of national music cultures, national composer schools and some individual author’s styles of the former USSR. Three evolution stages of all national music cultures are determined: “preprofessional”, “professional” and the stage of “new music”. Two work concepts are introduced: a Rakhmaninov’s musical and style canon as an individual system including characteristic properties of the composer’s style and poetics, and a national musical and style canon as a system of musical and expressive language principles typical for every musical culture and possessive of the national character. The signs representing the Rakhmaninov’s style are revealed and considered on the piano concerto genre. These two spheres outlined are disclosed in folklore and neofolklore conditions as the main evolution directions of the national musical thinking. The main principles of the Rakhmaninov’s and national canons interaction are singled out: adaptation corresponding to the early development stages of national music cultures (forlklore stage and assimilation (by G. Golovinsky characteristic for “new music” (neofollore stage. The problems are considered on the example of piano concertos by Z. Ismagilov, A. Khatchaturyan, A. Eshpay, R. Gazizov and some others.

    International Nuclear Information System (INIS)

    An approach to ground thermodynamics description using a coupled system of atmospheric regional climate and ground heat transfer models is improved by accounting for the time varying snow density. The simulations are compared to available observational analyses, and the sensitivity of the ground thermal regime to variable snow density is analysed. Projected changes of the ground thermal regime in the 21st century relative to the late 20th century are shown and compared to earlier estimates.

    The pigment composition of six painted metal knight shields of the Order of the Elephant dating from the second half of the 20th century belonging to the Danish royal collection were studied using Raman microscopy. By focusing a 785 nm laser with a 50× objective on particles in paint cross sections, it was possible to identify the following 20 compounds: hematite, goethite, chrome red/orange, chrome yellow, zinc chrome yellow, carbon black, toluidine red PR3, chlorinated para red PR4, dinitroaniline orange PO5, phthalocyanine blue PB15, indanthrone blue PB60, ultramarine, Prussian blue, lead white, anatase, rutile, calcium carbonate, barium sulphate, gypsum and dolomite. The components were frequently present in complex pigment mixtures. Additional information was obtained by elemental analysis with scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) to identify cobalt blue, zinc white and cadmium red, as well as to indicate the presence of zinc white in some pigment mixtures. The study allowed a comparison between the industrially applied preparation layers and the artistic paint layers applied by the heraldic painter. Differences in the choice of paint and pigment types were observed on the earliest knight shields, demonstrating a general delay of industrial materials into artist paints. PMID:26023056

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

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

  11. Composition of `Marbrite Fauquez' 20th-century opalescent glass: results of historical study and laboratory analyses

    Belgian Marbrite Fauquez opalescent glass is an innovative material developed at the take-off of the 20th century. S.A. Verreries de Fauquez produced this from 1922 onwards. Low maintenance requirements and appropriate properties in terms of hygienic aspects make these mass coloured glass plates popular as finishes for bathrooms, kitchens, hospitals, store fronts, decorative façade cladding,... Since production of Marbrite stopped in the 1960s, replacement of its applications in the framework of restoration procedures is almost impossible. Limited knowledge of the composition and production results in the lack of a proper conservation strategy. In order to improve the existing knowledge a historical research was conducted. Archive records including patents, literature, building specifications, plans, journals, advertisements, interviews with former directors of the glassworks, etc. were considered and evaluated. Onsite lifted samples of Marbrite glass were submitted to a laboratory investigation using optical and scanning electron microscopy. The results revealed crucial information about the original formula and components. This paper discusses the composition of Marbrite, a peculiar Belgian opalescent glass. This interdisciplinary research - a cooperation between the Vrije Universiteit Brussel and Royal Institute for Cultural Heritage - aims to improve the knowledge of Marbrite glass in order to develop repair and renovation techniques.

  12. Sediment accumulation in San Leandro Bay, Alameda County, California, during the 20th century - A preliminary report

    International Nuclear Information System (INIS)

    Major changes made in the configuration of San Leandro Bay, Alameda County, California, during the 20th century have caused rapid sedimentation within parts of the Bay. Comparison of bathymetric surveys indicates that sedimentation in the vicinity of the San Leandro Bay channel averaged 0.7 cm/annum between 1856 and 1984. Lead-210 data collected at four shallow water sites east of the San Leandro Bay channel indicated that sedimentation rates have averaged between 0.06 and 0.28 cm/annum. Because bioturbation of bottom sediments cannot be discounted, better definition of this range in sedimentation rates would require measuring the activity of lead-210 on incoming sediments. In addition to sediment deposited in the vicinity of the San Leandro Bay channel and open, shallow areas to the east, 850,740 cu m of sediment was deposited between 1948 and 1983 in an area dredged at the mouth of San Leandro Creek. All available data indicate that between 1,213,000 and 1,364,000 cu m of sediment was deposited in San Leandro Bay between 1948 and 1983. Sediment yield data from an adjacent drainage basin, when combined with inventories of lead-210 and cesium-137, indicate that most of the sediment deposited in San Leandro Bay is coming from resuspension of bottom sediments or from erosion of marshes or shorelines of San Leandro or San Francisco Bay. 31 refs., 7 figs., 4 tabs

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

    International Nuclear Information System (INIS)

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

    Long-term changes in nitrate concentration and flux between the middle of the 20th century and the first decade of the 21st century were estimated for the Des Moines River and the Middle Illinois River, two Midwestern Corn Belt streams, using a novel weighted regression approach that is able to detect subtle changes in solute transport behavior over time. The results show that the largest changes in flow-normalized concentration and flux occurred between 1960 and 1980 in both streams, with smaller or negligible changes between 1980 and 2004. Contrasting patterns were observed between (1) nitrate export linked to non-point sources, explicitly runoff of synthetic fertilizer or other surface sources and (2) nitrate export presumably associated with point sources such as urban wastewater or confined livestock feeding facilities, with each of these modes of transport important under different domains of streamflow. Surface runoff was estimated to be consistently most important under high-flow conditions during the spring in both rivers. Nitrate export may also have been considerable in the Des Moines River even under some conditions during the winter when flows are generally lower, suggesting the influence of point sources during this time. Similar results were shown for the Middle Illinois River, which is subject to significant influence of wastewater from the Chicago area, where elevated nitrate concentrations were associated with at the lowest flows during the winter and fall. By modeling concentration directly, this study highlights the complex relationship between concentration and streamflow that has evolved in these two basins over the last 50 years. This approach provides insights about changing conditions that only become observable when stationarity in the relationship between concentration and streamflow is not assumed.

    The study is focused on future changes in climate extremes over the northern Eurasia. The changes in the extreme indices for the mid 21st century relative to the late 20th century have been inferred from CMIP3 daily temperature and precipitation output. It has been found that modeling temperature extremes are in reasonable agreement with reanalysis. Future projections for the extremes in Northern Eurasia are prone to large uncertainties arising primarily from intermodel differences. The uncertainties for «warm» extremes are larger than for «cold» extremes not only due to greater model-to-model differences but also due to slower warming of the former. In the warm season the models project drier climate conditions over some regions of the northern Eurasia, longer droughts, fewer number of wet days and increased heavy precipitation intensity. The AOGCM simulated changes in the extremes lack credibility due to low spatio-temporal resolution of current global models. There is a pressing need to further investigate the impact related aspects of regional climate changes over the northern Eurasia using sufficiently large ensembles of RCM simulations at 10-50 km resolution. Currently, the most dramatic warming in Eurasia is expected to occur in the regions for which a very limited number of single RCM simulations exists (e.g., central and eastern Russia). The MGO RCM has been developed at 50 and 25 km resolutions for three domains: Western Russia, Siberia, and Europe. The regional climate change simulation has been performed and analysis of daily temperature variability and fire danger conditions has been carried out.

  17. Impacts of the EA and SCA patterns on the 20th century NAO-winter precipitation relationship in Europe

    2013-04-01

    Much of the 20th century multi-decadal variability in the NAO-winter precipitation relationship over the N. Atlantic / European sector can be ascribed to the combined effects of the North Atlantic Oscillation (NAO) and either the East Atlantic pattern (EA) or the Scandinavian pattern (SCA). The NAO, EA and SCA indices employed here are defined as the three leading vectors of the cross-correlation matrix calculated from monthly sea-level pressure anomalies for 138 complete winters from the 20CRv2 dataset (Compo et al., 2011). Winter precipitation data over Europe for the entire 20th century is derived from the high resolution CRU-TS3.1 climate dataset (Mitchell and Jones, 2005). Here we document for the first time, that different NAO/EA and NAO/SCA combinations systematically influence winter precipitation conditions in Europe as a consequence of NAO dipole migrations. We find that the zero-correlated line of the NAO-winter precipitation relationship migrates southwards when the EA is in the opposite phase to the NAO. This can be related to a south-westwards migration of the NAO dipole under these conditions, as shown by teleconnectivity maps. Similarly, a clockwise movement of the NAO-winter climate correlated areas occurs when the phase of the SCA is opposite to that of the NAO, reflecting a clockwise movement of the NAO dipole under these conditions. An important implication of these migrations is that they influence the spatial and temporal stationarity of climate-NAO relationships. As a result, the link between winter precipitation patterns and the NAO is not straightforward in some regions such as the southern UK, Ireland and France. For instance, much of the inter-annual variability in the N-S winter precipitation gradient in the UK, originally attributed to inter-annual and inter-decadal variability of the NAO, reflects the migration of the NAO dipole, linked to linear combinations of the NAO and the EA. Our results indicate that when the N-S winter precipitation gradient is accentuated by the occurrence of a positive EA during positive NAO winters, drier conditions than normal are found in the southern UK. This is consistent, for example, with the severe winter drought of 1976, when computed NAO and EA indices were both positive (0.97 and 1.87, respectively), illustrating the modulating effect of NAO/EA combinations on winter precipitation patterns in the southern UK.

    An important role in the formation of modern Lithuanian society was played by pharmacists who at the beginning of the 20th century were one of the most numerous parts of Lithuanian intelligentsia. They chose a job in a pharmacy not as a mission of life but due to political, social, and economic reasons. The majority of pharmacists were children of peasants who had refused to obey their parents and study in the seminary of priests. Those people who had been ousted from gymnasiums because of an anticzarist activity or those who had not finished school due to the lack of money also became pharmacists. Young men who had chosen a way of self-support left to the biggest cities of Russia and started the practice of an apprentice in a pharmacy. Later, they took examinations to become an assistant of a pharmacist, and after two years of studies at university, they took examinations of a pharmacist at last. Having got a diploma, they usually did not return to their motherland because there was a large network of pharmacies; thus, business conditions were harder, of course. They established pharmacies in various provinces of Russia most often, and it is supposed that only 10% of Lithuanian pharmacists worked in their native country. Living and working in a Russian environment, however, they enshrined national patriotic ideas, were active participants in social activities, published a Lithuanian professional newspaper "Farmaceutu reikalai" (translation, "Matters of pharmacists"), and attempted to unite all Lithuanians living in czarist Russia to struggle against denationalization, to encourage people to return to their motherland, and to work for its good. This article deals with the path for a career of Lithuanian pharmacists in czarist Russia and their national patriotic activity. PMID:19124967

  20. Comparison of 20th century and pre-industrial climate over South America in regional model simulations

    Full Text Available In this study, we assess how the anthropogenically induced increase in greenhouse gas concentrations affects the climate of central and southern South America. We utilise two regional climate simulations for present day (PD and pre-industrial (PI times. These simulations are compared to historical reconstructions in order to investigate the driving processes responsible for climatic changes between the different periods. The regional climate model is validated against observations for both re-analysis data and GCM-driven regional simulations for the second half of the 20th century. Model biases are also taken into account for the interpretation of the model results. The added value of the regional simulation over global-scale modelling relates to a better representation of hydrological processes that are particularly evident in the proximity of the Andes Mountains.

    Climatic differences between the simulated PD minus PI period agree qualitatively well with proxy-based temperature reconstructions, albeit the regional model overestimates the amplitude of the temperature increase. For precipitation the most important changes between the PD and PI simulation relate to a dipole pattern along the Andes Mountains with increased precipitation over the southern parts and reduced precipitation over the central parts. Here only a few regions show robust similarity with studies based on empirical evidence. However, from a dynamical point-of-view, atmospheric circulation changes related to an increase in high-latitude zonal wind speed simulated by the regional climate model are consistent with numerical modelling studies addressing changes in greenhouse gas concentrations.

    Our results indicate that besides the direct effect of greenhouse gas changes, large-scale changes in atmospheric circulation and sea surface temperatures also exert an influence on temperature and precipitation changes in southern South America. These combined changes in turn affect the relationship between climate and atmospheric circulation between PD and PI times and should be considered for the statistical reconstruction of climate indices calibrated within present-day climate data.

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

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

    Hydrocarbon contaminants are ubiquitous in urban aquatic ecosystems, and the ability of some microbial strains to degrade certain polycyclic aromatic hydrocarbons (PAHs) is well established. However, detrimental effects of petroleum hydrocarbon contamination on nondegrader microbial populations and photosynthetic organisms have not often been considered. In the current study, fatty acid methyl ester (FAME) biomarkers in the sediment record were used to assess historical impacts of petroleum contamination on microbial and/or algal biomass in South San Francisco Bay, CA, USA. Profiles of saturated, branched, and monounsaturated fatty acids had similar concentrations and patterns downcore. Total PAHs in a sediment core were on average greater than 20× higher above ?200 cm than below, which corresponds roughly to the year 1900. Isomer ratios were consistent with a predominant petroleum combustion source for PAHs. Several individual PAHs exceeded sediment quality screening values. Negative correlations between petroleum contaminants and microbial and algal biomarkers - along with high trans/cis ratios of unsaturated FA, and principle component analysis of the PAH and fatty acid records - suggest a negative impacts of petroleum contamination, appearing early in the 20th century, on microbial and/or algal ecology at the site.

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

    International Nuclear Information System (INIS)

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

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

  13. Impacts of 20th century aerosol emissions on the South Asian monsoon in the CMIP5 models

    L. Guo

    2014-12-01

    Full Text Available Comparison of single-forcing varieties of 20th century historical experiments in a subset of models from the Fifth Coupled Model Intercomparison Project (CMIP5 reveals that South Asian summer monsoon rainfall increases towards the present day in Greenhouse Gas (GHG-only experiments with respect to pre-industrial levels, while it decreases in anthropogenic aerosol-only experiments. Comparison of these single-forcing experiments with the all-forcings historical experiment suggests aerosol emissions have dominated South Asian monsoon rainfall trends in recent decades, especially during the 1950s to 1970s. The variations in South Asian monsoon rainfall in these experiments follows approximately the time-evolution of inter-hemispheric temperature gradient over the same period, suggesting a contribution from the large-scale background state relating to the asymmetric distribution of aerosol emissions about the equator. By examining the twenty-five available all-forcings historical experiments, we show that models including aerosol indirect effects dominate the negative rainfall trend. Indeed, models including only the direct radiative effect of aerosol show an increase in monsoon rainfall, consistent with the dominance of increasing greenhouse gas emissions and planetary warming on monsoon rainfall in those models. For South Asia, reduced rainfall in the models with indirect effects is related to decreased evaporation at the land surface rather than from anomalies in horizontal moisture flux, suggesting the impact of indirect effects on local aerosol emissions. This is confirmed by examination of aerosol loading and cloud droplet number trends over the South Asia region. Thus while remote aerosols and their asymmetric distribution about the equator play a role in setting the inter-hemispheric temperature distribution on which the South Asian monsoon, as one of the global monsoons, operates, the addition of indirect aerosol effects acting on very local aerosol emissions also plays a role in declining monsoon rainfall. The disparity between the response of monsoon rainfall to increasing aerosol emissions in models containing direct aerosol effects only and those also containing indirect effects needs to be urgently investigated since the suggested future decline in Asian anthropogenic aerosol emissions inherent to the representative concentration pathways (RCPs used for future climate projection may turn out to be optimistic. In addition, both groups of models show declining rainfall over China, also relating to local aerosol mechanisms. We hypothesize that aerosol emissions over China are large enough, in the CMIP5 models, to cause declining monsoon rainfall even in the absence of indirect aerosol effects. The same is not true for India.

  15. Climatic changes between 20th century and pre-industrial times over South America in regional model simulations

    S. Wagner

    2011-09-01

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

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

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

    Precipitation differences show a more heterogeneous pattern, especially over tropical regions. This might be explained by changes in convective processes acting on small scales. During southern summer wetter conditions are evident over the Amazonian and Parana basin in the present-day simulation. Precipitation increases are evident over Patagonia together with decreases to the north along the western slope of the Andes Mountains. During southern winter also a dipole pattern along the Andes Mountains with wetter conditions over the southern parts and drier conditions over the central parts is evident. An interesting feature relates to precipitation changes with changing sign within a few 10th of kilometers along the southern parts of the Andes mountain chain. This pattern can be explained by changes in large-scale circulation related to latitudinal changes of the extratropical southern hemispheric westerlies.

    Full Text Available At the end of the 19th and beginning of the 20th century, the evolution of American multiple-dwelling architecture was marked by the passage from the standard construction of single-family standalone homes and row houses to a new housing typology which corresponded to all of the new urban planning rules and requirements of the contemporary way of life in cities. New York was the first American city to face the problem of dense settlement in limited spaces. The »U, E, H« ground plan designs were developed and were most commonly used during the period when the Building Zone Resolution adopted in 1916 by New York City was in force. The Building Zone Resolution introduced another novelty into New York town planning, i.e. the setting back of exterior walls above a determined height. Consequently, this gave rise to buildings with stepped profiles and many more storeys. The solutions developed by the New York residential architecture were adopted by other cities and further developed in line with specific local influences. Chicago is the most interesting of these cities; between 1924 and 1929 several quality housing complexes were built there which strongly deviated from the then housing construction in New York by the consistent ground plan designs of structures and apartment designs.

    We present observations of the long-term recession of surging outlets of Icelandic ice caps in response to 20th century climate. In August 1998, synthetic aperture radar (SAR) data, covering the western part of Vatnajokull and the northern part of Myrdalsjokull in southern Iceland, were acquired with the Danish airborne EMISAR radar system. Polarimetric and interferometric SAR data reveal the margins of the present ice caps as well as a series of terminal moraines in the fore field. These moraines date back to the maximum Neoglacial extent at the end of the 19th century and the outermost allow reconstruction of the margin at that time. The data offer a unique opportunity to estimate the area decrease of these ice caps in the 20th century. The influence of the fluctuations of the surge type outlets, constituting most of W-Vatnajokull area and a good part of N-Myrdalsjokull area, is minimal, since they had all recently surged in 1998 as was presumably the case when the outermost moraines were formed. The major contributor to the area decrease is therefore climate changes in the 20th century even though the glacier retreat has been interrupted by short-lived surges. Moraines associated with most of the surges in W-Vatnajokull in the 20th century are observed in the SAR data including the most recent surges in the 1990s. Interestingly no push moraines were observed in front of the surge advance, but the moraines appear when the glaciers start retreating. We estimate that the collective decrease of the outlets of western Vatnajokull since maximum Neoglacial extent of each outlet, is log km(2) (6.7%) corresponding to an average retreat of 850 in over a 130 km long margin. In the same period the outlet Slettjokull, in N-Myrdalsjokull, has decreased by 33 km(2) (20%) corresponding to an average retreat of 1500 in over a 20 kin long margin. (c) 2005 Elsevier B.V.

  20. Quantifying the role of fire in the Earth system - Part 2: Impact on the net carbon balance of global terrestrial ecosystems for the 20th century

    Fire is the primary form of terrestrial ecosystem disturbance on a global scale. It affects the net carbon balance of terrestrial ecosystems by emitting carbon directly and immediately into the atmosphere from biomass burning (the fire direct effect), and by changing net ecosystem productivity and land-use carbon loss in post-fire regions due to biomass burning and fire-induced vegetation mortality (the fire indirect effect). Here, we provide the first quantitative assessment of the impact of fire on the net carbon balance of global terrestrial ecosystems during the 20th century, and investigate the roles of fire's direct and indirect effects. This is done by quantifying the difference between the 20th century fire-on and fire-off simulations with the NCAR Community Land Model CLM4.5 (prescribed vegetation cover and uncoupled from the atmospheric model) as a model platform. Results show that fire decreases the net carbon gain of global terrestrial ecosystems by 1.0 Pg C yr-1 averaged across the 20th century, as a result of the fire direct effect (1.9 Pg C yr-1) partly offset by the indirect effect (-0.9 Pg C yr-1). Post-fire regions generally experience decreased carbon gains, which is significant over tropical savannas and some North American and East Asian forests. This decrease is due to the direct effect usually exceeding the indirect effect, while they have similar spatial patterns and opposite sign. The effect of fire on the net carbon balance significantly declines until ?1970 with a trend of 8 Tg C yr-1 due to an increasing indirect effect, and increases subsequently with a trend of 18 Tg C yr-1 due to an increasing direct effect. These results help constrain the global-scale dynamics of fire and the terrestrial carbon cycle.

    Fire is the primary terrestrial ecosystem disturbance agent on a global scale. It affects carbon balance of global terrestrial ecosystems by emitting carbon to atmosphere directly and immediately from biomass burning (i.e., fire direct effect), and by changing net ecosystem productivity and land-use carbon loss in post-fire regions due to biomass burning and fire-induced vegetation mortality (i.e., fire indirect effect). Here, we provide the first quantitative assessment about the impact of fire on the net carbon balance of global terrestrial ecosystems for the 20th century, and investigate the roles of fire direct and indirect effects. This study is done by quantifying the difference between the 20th century fire-on and fire-off simulations with NCAR community land model CLM4.5 as the model platform. Results show that fire decreases net carbon gain of the global terrestrial ecosystems by 1.0 Pg C yr-1 average across the 20th century, as a results of fire direct effect (1.9 Pg C yr-1) partly offset by indirect effect (-0.9 Pg C yr-1). Fire generally decreases the average carbon gains of terrestrial ecosystems in post-fire regions, which are significant over tropical savannas and part of forests in North America and the east of Asia. The general decrease of carbon gains in post-fire regions is because fire direct and indirect effects have similar spatial patterns and the former (to decrease carbon gain) is generally stronger. Moreover, the effect of fire on net carbon balance significantly declines prior to ~1970 with trend of 8 Tg C yr-1 due to increasing fire indirect effect and increases afterward with trend of 18 Tg C yr-1 due to increasing fire direct effect.

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

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

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

    Marxism was indeed vulgarized due to scientism in the 20th century, which even limits the development of Chinese social theories nowadays. This paper put forward the idea that it was serious misunderstanding to interpret Marx as prophet or inventor like empiricists who regard finding out eternal laws as the goal of science. In fact, Marx did not propose any so-called “natural laws of historical development”. He articulated that the only thing worth to do was to take note of what happened befo...

  7. Abrupt and severe 20th Century changes in the fire regimes of southeastern Australia: Evidence from a 3000 year multi-proxy analysis

    Fire is the dominant natural disturbance in southeastern Australia. For millennia it has been the driving force shaping terrestrial ecosystems in the region -- simultaneously killing vegetation and initiating regeneration across whole landscapes. Fire regimes across the region are driven by several factors including climate, vegetation, and ignition sources. Humans have been a significant contributing factor to past and present fire regimes. Prior to European settlement in the late 1700s, Aboriginal Australians used frequent, low-intensity fires to manage vegetation across much of the landscape. European settlement led to the displacement of Aboriginal communities and a shift to active fire suppression and control. This changing approach to fire management is widely believed to have initiated a fundamental shift towards extreme, high-intensity fire events as fuel loads increased. In addition, during the 20th Century prolonged periods of warm, dry conditions have occurred with greater frequency and intensity. The relative importance of climate and fire management practices on contemporary fire regimes is vigorously debated in Australia and is directly relevant to land management policies and their implementation. To put the current fire regime into historical context, we used a multi-proxy approach combining palaeo-charcoal and tree-ring analyses to assess how fire regimes have changed over the last 3000 years in the Snowy Mountains region of southeastern Australia. We found almost no evidence of high-intensity fires in the 3000 years that preceded the 20th Century. However, in the mid-20th Century there is a sudden and dramatic increase in the presence of charcoal and the pulsed establishment of trees across the landscape, suggesting a recent shift from low-intensity fires with minimal charcoal signatures to moderate- to high-intensity fires with substantial charcoal inputs. Importantly, the tree-ring data demonstrate that most of these fires were not stand-replacing and led to the establishment of multiple-age cohorts. While there is a clear shift in the fire regime in the 20th Century, the intensification of fire occurs nearly 150 years after European settlement in this area and has led to the establishment of complex, multi-aged forests across the landscape, suggesting an important interaction between fire management practices associated with European settlement and changing climatic conditions.

Abstract in english Under the light of Labovian Sociolinguistics, I take the Brazilian Portuguese connectors E, AÍ, DAÍ, and ENTÃO as variants of the dependent variable "retroactive-propeller sequenciation". The data come from the following sources: (i) "The grapes of wrath", an novel written by John Steinbeck in 1939, [...] the 1940 Brazilian Portuguese translation of which is marked by spoken language traits of the working classes from Rio Grande do Sul (RS), the most southern Brazil State; (ii) 48 interviews from the VARSUL Data Base of Florianópolis (the capital of Santa Catarina State), which were collected during the last decade of the 20th century. My goal are: (i) to seek evidence of change in real time, (ii) to seek evidence of change in apparent time by controlling the social variable 'age', (iii) to interrelate the results regarding the variable 'age' in both periods of time. The results present evidences of change in both real time and apparent time. Moreover, I set up an inter-relationship between the results regarding the variable 'age' at the end of the first half of the 20th century and at the end of the second half of the 20th century. Based on this inter-relationship, I was able to trace a more detailed picture of the changes the connectors E, AÍ, DAÍ, and ENTÃO possibly underwent throughout the 20th century.

  14. ENSO variability in the western tropical Pacific during the 20th and 14th centuries: preliminary results from a ~700 year coral

    Understanding El Niño Southern Oscillation (ENSO) variability prior to anthropogenic influence is crucial to understanding natural climate variability and to informing predictions of future climate change. Coral-based climate records from ENSO-sensitive regions provide unique high-resolution archives of past ENSO variability. However, the massive coral most commonly used in climate studies, Porites spp., rarely provide climate record lengths in excess of 200 years. This presents a challenge because recent work suggests that proxy records of ENSO variability need to exceed 500 years in length in order to capture the full range of natural variability of the ENSO system. Here we present preliminary oxygen isotope (?18O) data from a slower growing, ~700 year long Diploastrea heliopora coral from Lambumbu Bay, Vanuatu (LBV; 16.19°S, 167.39°E), located at the southern edge of the Western Pacific Warm Pool (WPWP). Coral-based climate records from this region have been shown to be reliable recorders of ENSO-related variability of the South Pacific Convergence Zone (SPCZ). The LBV coral was drilled live in 2010 and the bottom of the coral has a U-Th date of 1228 ± 10 CE. Our initial focus is to characterize and compare the geochemical variability recorded in the oldest (14th century) and youngest (20th century) sections of the coral. We observe a ?18O anomaly during the 14th century similar in magnitude to the ?18O anomaly associated with the 1997-1998 ENSO warm-phase event. We also observe that coral ?18O values in the 14th century are enriched by ~ 0.9‰, relative to modern coral ?18O values, which likely reflects salinity differences. Finally, 20th century coral ?18O variability agrees well with a previously published ?18O record from a Porites lutea coral (Sabine Bank, Vanuatu, ~130 km away) providing us with confidence in using Diploastrea heliopora corals for multicentury, continuous coral-based paleoclimate reconstructions.

    Full Text Available At the end of the 19th and the beginning of the 20th century, due to the initiative of Russian government and Orthodox Church, several grand churches were built in Vilnius. The development and restoration of Catholic sacral objects were practically restricted until the end of Russian rule in 1915, but at the beginning of the 20th century, this restriction was slightly defused. The Catholic community of Vilnius seized this opportunity and began an action of sav-ing sacral objects. The churches of St. Ann and St. Michel and the interior of St. Peter and Paul’s church were restored. The development of new churches in Vilnius was enabled after revolution-ary events in 1905–1907 when tsarist authorities were forced to make some abatements for the people of the enslaved country. A small Catholic church in the actual Gerosios Vilties street and the church of St. Kasimir in Naujoji Vilnia were built, the construction of Blessed Virgin Mary church was started in Žv?rynas and a modern church of Holy Heart of Jesus was not completed. Article in Lithuanian

    Full Text Available A 137 m ice core drilled in 1999 from Eastern Bolivian Andes at the summit of Nevado Illimani (16º 37' S, 67º 46' W, 6350 m asl was analyzed at high temporal resolution, allowing a characterization of trace elements in Andean aerosol trapped in the ice during the 20th century. The upper 50 m of the ice core were dated by multi-proxy analysis of stable isotopes (d18O and d2H, 137Cs and Ca+2 content, electrical conductivity, and insoluble microparticle content, together with reference historical horizons from atmospheric nuclear tests and known volcanic eruptions. This 50 m section corresponds to a record of environmental variations spanning about 80 years from 1919 to 1999. It was cut in 744 sub-samples under laminar flow in a clean bench, which were analyzed by Ion Chromatography for major ionic concentration, by a particle counter for insoluble aerosol content, and by Inductively Coupled Plasma Mass Spectrometry (ICP-MS for the concentration of 45 chemical species from Li to U. This paper focuses on results of trace element concentrations measured by ICP-MS. The high temporal resolution used in the analyses allowed classifying samples as belonging to dry or wet seasons. During wet season elemental concentrations are low and samples show high crustal enrichment factors. During dry seasons the situation is opposite, with high elemental concentrations and low crustal enrichments. For example, with salt lakes as main sources in the region, average Li concentration during the 20th century is 0.035 and 0.90 ng g-1 for wet and dry seasons, respectively. Illimani average seasonal concentration ranges cover the spectrum of elemental concentration measurements at another Andean ice core site (Sajama for most soil-related elements. Regional crustal dust load in the deposits was found to be overwhelming during dry season, obfuscating the contribution of biomass burning material. Marked temporal trends from the onset of 20th century to more recent years were identified for the concentrations of several trace species of anthropic origin, especially for Cu, As, Zn, Cd, Co, Ni and Cr. Among these elements, Cu shows average wet season crustal enrichment factors above 103, while the others range between 102 to about 5x102. P and K show moderate average wet season enrichment factors, suggesting an impact of natural biogenic emissions from the Amazon Basin. Pb has multiple anthropic sources in the region, from mining activities in the beginning of 20th century to automotive fuel after 1950s. From the large number of samples analyzed from Illimani, it was possible to derive an effective chemical characterization of the deposited background Andean soil dust aerosol during 20th century.

  18. On a set of 20th century monumental events that shaped the modern discipline of ocean wind wave's research

    Liu, P.

    2012-04-01

    History is made up of individual events. The modern ocean wind waves research has been active for nearly 70 years since the early years of the decade of 1940's while the World War II was still fighting in earnest and Sverdrup and Munk were embarked on an unprecedented attempt to make wave condition prediction for Navy Amphibious forces carrying out landing operation. That was certainly a monumental event that started the modern ocean wind wave's research. Here I wish to present a set of other monumental events in the intervening years which, in my personal view, are vital to the formation of our present day conventional ocean wind wave's research: • Circa 1945: The war time invention of underwater pressure wave gage that measures pressure fluctuations induced by surface waves and also marked as the start of single-point wave measurements prevalent today. • Circa 1950: When oceanographer Pierson met statistician Tukey and ocean wave spectrum analysis was thereby born. • Circa 1952: Something old something new - Longuet-Higgins introduced the distribution function of Load Rayleigh to the emerging ocean wave data analysis and Rayleigh distribution has been the mainstay of ocean wind wave's research ever since. • Circa 1953: Neumann started the quest to formulate a wind wave spectrum with his impressive first empirical spectrum before spectrum was widely measured. • Circa 1957: Phillips worked out the resonance theory for wind wave's generation. • Circa 1957: Miles simultaneously developed the shear flow model for wind wave's generation, complementary to Phillips theory. • Circa 1959: Hasselmann formulated the source function to start the first framework of comprehensive wind wave modeling. These are all the basic innovative milestones that the bulk of the conventional ocean wind wave research studies today were evolved from. While the monumental status of these works may represent merely the personal opinion of a single aficionado, I do feel that they were the ones that sowed a rich fertile ground from which a whole sphere of wind wave's research over the last 7 decades was stemmed from and also most of today's practices in ocean wind wave's research were evolved, directly or indirectly, from those original works. As we are now well into the second decade of the 21st century, we can only hope that at some time, a new period of rejuvenation like those flowerishing 1950's can be reshaped to further expand our knowledge on the wind wave research to take further advantages of the many new technological advancements of the new century has to offer and lead us to the true understanding of the ubiquitous but still elusive ocean wind waves which we are all mesmerized to study them!

  19. The Influence of Canadian Intellectuals’ Ideological Views on the Political Culture in Canada at the Beginning of the 20th Century

    SOKOV I.A.

    2014-06-01

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

    Full Text Available [...] Abstract in english Due to the strategies implemented by post-Independence Ibero-American states to curtail political participation, exile was mainly reserved as a privilege for ostracized members of the elite, who drew on their support networks in the process. The late 19th and early 20th centuries witnessed a process [...] of "mass exile", expressed by a growing number of exiles from different social classes, excluded due to their participation in politics and public spheres. The expansion of institutional exclusion spawned solidarity networks and increasing attention by the international community towards politics in the exiles' home countries. Old domestic political issues found a transnational echo, based on a growing concern over human rights violations and political persecution. This process produced a radical transformation in the structure, impact, and functioning of political exile from Ibero-American countries.

    Full Text Available During the 20th century, the 'subject' of knowledge (i.e. the individual scientist or a scientific community) was attributed an increasingly relevant role in (the philosophy of) science. Anchoring scientific knowledge to the subject (rather than to the object, as in early positivism) was proposed as [...] a 'liberating' move, leading to a less authoritarian and rationalistic view of science. This article provides a reformational point of view on the topic. A historical documentation of the shift to the subject is provided by visiting the philosophies of Popper, Kuhn, Collins and others. It is argued that the promise of a more libertarian or emancipating conception of science was challenged by several problems. In particular, the conflict between an individual and a communal understanding of the subject is highlighted. Furthermore, it is argued that the roots of the phenomenon in most cases remain hidden. An interpretation of the shift and the sketch of an alternative approach conclude the article.

    The Arveyron of the Mer de Glace is the emissary of the most famous and largest French glacier. The latter has dramatically shrunk since the end of the Little Ice Age (LIA), such as every alpine glacier: the front has registered a retreat of 2.7 km since 1820 and a recent modelling showed a likely decrease of an extra km by 2040. The Arveyron and its surroundings are deeply impacted by the retreat. Then, dynamics of proglacial streams and of lateral moraines have been studied at different time and space scales through various methods: airborne and terrestrial Lidar DEM comparisons, mapping from orthophotos, 2D and 3D monoplotting to quantify past events from old terrestrial pictures, etc. By coupling studies on moraines and on stream morphology we wanted to better understand the influence of glacier retreat on sediment supply and transport downstream. Results show the evolution of the stream sediment sources linked to the glacier retreat. Before the middle of the 20th century, till was the main sediment source and was released by major flood events such as GLOFs. Now, geomorphic activity is especially important on the right lateral moraine into the recently deglaciated hanging valley of the Mer de Glace but also in the moraine flanks of the current glacier tongue (many landslides occurred during the Summer 2014). The recent glacier retreat has also formed sediments sinks such as two proglacial lakes which are progressively filling. These lakes work as big sediment traps until they will disappear (around 2017). Fluvial dynamics of the Arveyron depends on the connectivity with potential sediments sources. This is why we crossed upstream studies with the channel evolution on its fan. Arveyron channel has got narrower and incised for at least a century. Such evolution should mean a decreasing sediment yield, but anthropic factors play also an important role on stream morphology. The main anthorpic impact is the complex subglacial harnessing of the Mer de Glace. The Arveyron discharge is totally by passed up to the restitution channel, even during flood events. Evolution of the paraglacial area, but also downstream, is thus largely influenced by that facility. Finally we used recent modelling of the Mer de Glace retreat for the next decades to comprehend the future paraglacial landscapes and what the Arveyron dynamics should become. Excepted small threshold effects, no major evolution should occur.

    This paper investigates trends in the history of names for psychiatric institutions in Germany in the 20 (th) century. Professional lobbyism as well as efforts to fight stigmatisation of mentally ill patients form the background for name changes. The replacement of the term "Heil- Und Pflegeanstalt" ("Institution for the Cure and Care") by "Krankenhaus" ("hospital") in the 1950s/1960s, when through the introduction of modern psychopharmaceuticals psychiatry finally got acknowledged as an equal medical discipline and at the same time broke with the dreadful heritage of Nazi psychiatry, was a major step. The unity of the hospital itself and complimentary mental health care institutions is often expressed by "Zentrum" ("centre") as is the preservation of the patients' ties and their reintegration into the community by "Soziale Psychiatrie".

  8. Long-term Trends in Interplanetary Magnetic Field Strength and Solar Wind Structure during the 20th Century

    Lockwood et al have recently reported an approximately 40% increase in the radial component of the interplanetary magnetic field (IMF) at Earth between 1964 and 1996. We argue that this increase does not constitute a secular trend but is largely the consequence of lower than average fields during solar cycle 20 (1964-1976) in comparison with surrounding cycles. For times after 1976 the average IMF strength has actually decreased slightly. Examination of the cosmic ray intensity, an indirect measure of the IMF strength, over the last five solar cycles (19-23) also indicates that cycle averages of the IMF strength have been relatively constant since approximately 1954. We also consider the origin of the well-documented increase in the geomagnetic alphaalpha index that occurred primarily during the first half of the twentieth century. We surmise that the coronal mass ejection (CME) rate for recent solar cycles was approximately twice as high as that for solar cycles 100 years ago. However, this change in the CME rate and the accompanying increase in 27-day recurrent storm activity reported by others are unable to account completely for the increase in alphaalpha. Rather, the CMEs and recurrent high-speed streams at the beginning of the twentieth century must have been embedded in a background of slow solar wind that was less geoeffective (having, for example, lower IMF strength and/or flow speed) than its modern counterpart.

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

    Directory of Open Access Journals (Sweden)

    Eduardo Prieto González

    2013-10-01

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

    Full Text Available La escolarización de masas fue un asunto público que ocupó la atención de intelectuales, políticos y pedagogos en la transición del siglo XIX al XX. La obligatoriedad de la enseñanza representó un paso importante aunque insuficiente: más de 50 por ciento de la población en edad escolar seguía siendo [...] analfabeta y la oferta educativa se concentraba en las ciudades en un país donde 70 por ciento de la población vivía en el campo. En el proceso de construir la escolarización pública de masas se traza una curva de pensamiento que muestra replanteamientos en las concepciones sobre "el pueblo" y las formas de vincularlo con el desarrollo de la nación. El artículo enfoca la instrucción rudimentaria de principios del siglo XX y propone que esta experiencia de escolarización preparó para una "ruptura relativa" en la constelación de ideas sobre quién es el pueblo y cómo educarlo entre finales del XIX y la escuela rural que despunta en la posrevolución. Abstract in english The schooling of the masses has been a public affair that took up the attention of intellectuals, politicians and educators during the transition period between the 19th and the 20th Century.

This process of building up the public schooling of masses shows a thinking curve that makes necessary to rethink the conceptions about "the people" and the ways to connect it with the development of the nation. The article focuses on the rudimentary education of the beginnings of the 20th Century and proposes that this schooling experiment was the starting point for a "relative breaking-of" within the constellation of ideas about who is the people and how to educate it between the end of the 19th Century and the rural school that comes up affer the Mexican Revolution.

    An extended array of carbonaceous species including elemental carbon (EC), water insoluble organic carbon (WinOC) as well as dissolved organic carbon (DOC), humic-like substances (HULIS), and single organic compounds like carboxylic acids, levoglucosan, and cellulose was investigated for the first time in Alpine snow deposits. These investigations were done on selected discrete ice cores sections extracted from Mount Rosa and Mount Blanc glaciers covering the 20th century and extending back to previous centuries. Here we focus on major changes in summer ice layers. Among carbonaceous components, EC reveals an outstanding increase with a sharp summer increase after World War II. This result is discussed against available past EC emission inventories in Europe which are thought to be mainly driven by emissions from road transport and residential sector. The long-term trend of organic carbon (OC) aerosol preserved in ice, WinOC as well as water soluble organic carbon (WSOC), was successfully reconstructed using the suitable array of organic compounds we investigated in this study. It is shown that the level of OC preserved in ice has increased by a factor of 2 after 1950 likely as a result of the enhancement of the oxidative capacity of the atmosphere over the last decades producing more secondary organic atmospheric aerosol from biogenic gaseous precursors.

Starting from the late nineteenth century, northwest China, Eastern Turkestan (modern Xinjiang, and eastern Tibet became increasingly attractive destinations for foreign travelers and explorers. There was a veritable 'run' on the region, which was deemed one of the last blank spots on world maps. In addition, northwest China, Tibet, and Eastern Turkestan received special attention because of competition between the British and Russian empires as part of what is known as the Great Game in Central Asia. This caused other European countries such as France, Belgium, and Germany to fear that they would miss out on new geographic and scientific discoveries. Apart from geo-political, economic, and archeological incentives, Tibetan Buddhism also attracted considerable interest, although mostly on a 'touristic', rather than an academic, level.

  14. Changes in mercury and cadmium concentrations and the feeding behaviour of beluga (Delphinapterus leucas) near Somerset Island, Canada, during the 20th century

    International Nuclear Information System (INIS)

    Beluga (Delphinapterus leucas) continues to be an important food species for Arctic communities, despite concerns about its high mercury (Hg) content. We investigated whether Hg and cadmium (Cd) concentrations had changed during the 20th century in beluga near Somerset Island in the central Canadian Arctic, using well-preserved teeth collected from historical sites (dating to the late 19th century and 1926-1947) and during subsistence hunts in the late 1990s. Mercury concentrations in both historical and modern teeth were correlated with animal age, but 1990s beluga exhibited a significantly more rapid accumulation with age than late 19th century animals, indicating that Hg concentrations or bioavailability in their food chain had increased during the last century. The geometric mean tooth Hg concentration in modern 30 year old animals was 7.7 times higher than in the late 19th century, which corresponds to threefold higher concentrations in muktuk and muscle. Teeth from 1926 to 1947 were similar in Hg content to the late 19th century, suggesting that the increase had occurred sometime after the 1940s. In contrast, tooth Cd was not correlated with animal age and decreased during the last 100 years, indicating that anthropogenic Cd was negligible in this population. Late 19th century beluga displayed a greater range of prey selection (tooth ? 15N values: 15.6-20.5%o) than modern animals (? 15N: 17.2-21.1%o). To prevent this difference from confounding the temporal Hg comparison, the Hg-age relationships discussed above were based on historical animals, which overlapped isotopically with the modern group. Tooth ? 13C also changed to isotopically more depleted values in modern animals, with the most likely explanation being a significant shift to more pelagic-based feeding. Industrial Hg pollution is a plausible explanation for the recent Hg increase. However, without further investigation of the relationship between the range exploitation of modern beluga and their possible exposure to regional marine food chains with (naturally) higher Hg contents than their historical counterparts, we cannot unequivocally conclude that the increase was anthropogenically driven

    Trends in many surface climate variables have already been observed worldwide. These can then be compared with atmosphere-ocean general circulation (AOGCM) simulations to identify the influence of human-induced warming. However, many trends in surface climate are likely being driven by changes in atmospheric circulation patterns. Here, we cluster geopotential and surface pressure fields from ERA-40 and NCEP reanalysis for the period 1948-2002 to identify five dominant seasonal circulation patterns over North America that are strongly correlated with seasonal temperature anomalies. Several of these patterns show trends that are significant at the 95th confidence level, including increasing frequency of the dominant summer pattern in the "transition" months leading up to and following summer (June, September, and October). These results suggest that typically summer-like patterns are already occurring earlier in the year and lasting longer into the fall than the used to a few decades ago. Simulations from the PCM model also show similar seasonal patterns over the historical period, although the trends appear less distinct. Over the coming century, however, significant increases in the frequency of summer patterns and decreases in winter patterns are seen, particularly under a higher as compared with a lower emissions scenario.

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

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

    2007-10-01

    Carlos Younger de la Peña (1920-1996) was one of the representative urologists of his time, both in urology as a whole and particularly in urology in Madrid, during the 40 years between 1945 to 1985. His professional training was linked to the department of urology in the "La Princesa" Hospital chaired by Dr. Pedro Cifuentes Díaz first and Luis Cifuentes Delatte posteriorly. The important influence of French urology led Carlos Younger to complete his studies in the departments of urology chaired by professors J. Cibert (Lyon), Truc (Montpellier) and Couvelaire (Paris). When he returned from France he completed his doctoral thesis with the title "Experimental study on the ureterosigmoidostomy type Coffey I" directed by Prof. J. Garcia Orcoyen in 1957. His first publications started in 1946 and he ended with almost 100, including communications to various speciality congresses and meetings. Established in his private clinic in the Ferraz Street in Madrid he alternated his professional practice between Social Security patients and the Red Cross Central Hospital. At the end of his life he had collected near to 10.000 patients' clinical records. He was member of various scientific societies (among them the International Society Of Nephrology) and received various awards such as the one from the Pediatric Surgeons Association for his work on "bladder exstrophy "and the one from the Medical Academy of Valladolid for his study "Vascular renal hypertension". In 1961 he performed the second renal transplant in Spain. His professional interest was preferentially focused on uro-oncology, pediatric urology, gynecologic urology, and endoscopic surgery. He left many disciples with the same interests. The professional life of Carlos Younger de la Peña, in the period of time under analysis, is much significant as a reflex of the evolution of urology and urologists over half a century.

To Slovenes, China was then seen as a faraway land that had been visited by some Slovene missionaries, noblemen and travellers throughout the past centuries. Nevertheless, much interest was expressed by the Slovene public and press in the events surrounding the Boxer Rebellion. Despite the fact that the Austro-Hungarian military was part of the international coalition that intervened in Chinese internal affairs, the leading Slovene newspapers of the period supported the right of the Chinese people to defend their country against the big powers of the time, who tried to dismember China and enforce the regime of capitulation.Keywords: China, Slovenia, Boxer Rebellion, Austria-Hungary, Tientsin Izvle?ek?lanek obravnava slovenske reakcije na intervencijo osmih koalicijskih sil na Kitajskem med tako imenovano boksarsko vstajo na Kitajskem leta 1900.

  3. Assessing how seasonal hydrological balance has changed during the warming 20th century in the montane forests of Southeast Asian monsoon region using a stable isotope dendroclimatology approach

    Tropical montane forests act as water catchment and host of biodiversity in the Southeast Asian monsoon region, and understanding how their hydrological conditions change with global warming is vitally important. Global climate model simulations project enhanced moisture cycle in the tropics, which would cause stronger summer monsoon precipitations, but on the other hand the adiabatic lapse rate would be shifted towards a moister condition (amplification of warming at high elevation), inhibiting dry season orographic lifting cloud/fog formation (lifting cloud base hypothesis), enhancing evapo-transpiration, and leading to a net moisture loss during winter dry season. In this study, we have attempted to investigate how the seasonal moisture balance in Southeast Asia has evolved in response to these influences through the 20th century using the oxygen isotopic composition (?18O) of subannual tree cellulose samples extracted from the annual rings of pine trees that grow in Doi Chiang Dao, a limestone mountain in northern Thailand. At this location the ?18O of cellulose exhibits distinctive annual cycles of up to 12‰, which is primarily a reflection of both the so-called ‘isotope amount effect’ that is associated with the strong monsoon precipitation during summer wet season and the moisture availability from different sources during winter dry season. We have demonstrated that tree cellulose ?18O could be used as a proxy for regional monsoon strength by showing that the annual mean cellulose ?18O correlate significantly with All India Rainfall, Webster-Yang monsoon index, as well as with both local and regional monsoon precipitation. ENSO is the dominant influence on interannual rainfall variability and this is well expressed in the interannual cellulose ?18O record. Using a 21-year moving window correlation analysis we find a weakening of ENSO influence after 1980, coinciding with the most rapid atmospheric warming. We expect to analyze older trees to reconstruct monsoon behavior beyond the instrumental period. Further we find that the annual cellulose ?18O maxima, which represent the ?18O of soil moisture in winter dry season, has decline progressively by about 3.5‰ over the 80 years. We interpret this 20th century trend to reflect a smaller contribution of isotopically enriched fog drip to soil moisture, and propose that both global warming and low land deforestation have resulted in reduced dry season fogginess/cloudiness. This would imply that the dry season moisture budget of these tropical montane forests has shifted towards dryer conditions, with a possible impact on biodiversity in this region. We intend to test this hypothesis against a longer and more regionally extensive data set of cellulose isotope records.

    Full Text Available Mykolas Birziska (1882–1962 was a prominent Lithuanian scholar and politic, a signatory of the Act of Independence (1918, a member of Lithuanian Council (1917–1920, director of the first Lithuanian Gymnasium of Vytautas the Great in Vilnius (1915–1922, professor and rector of Kaunas and Vilnius universities. This articles deals with his early journalistic activities and editorship in the press in Vilnius before the outbreak of the First World War, and seeks to analyze the formation of his intellectual and political attitudes. In 1905, being a member of the Party of Lithuanian Social Democrats, Birziska began his journalistic career in socialist press. In 1906 heedited a party newspaper “Echo” in Polish language, where his specific interest in cooperation between different nationalities first became vivid. At the same time he began contributing to theliberal and antinationalist newspaper of the Polish krajovtsy movement “Gazeta Wileñska” (edited by Michal Römer, that argued for the political equality and tolerant cultural coexistence of allthe national groups in Lithuania. After the closure of “Gazeta Wileñska”, Birziska in 1907–1908 cooperated with another liberal daily in Russian language “Severo-Zapadnyj Golos”. Writing in threelanguages and simultaneously contributing to Lithuanian, Polish, and Russian press, Birziska exercised a specific role of a publicist as a mediator between different cultural groups in the multinational city. Professional analysis of the national conflicts, the principals of cultural tolerance and liberal antinationalist outlooks became the dominant features of his trilingual journalistic texts. Consequently, Birziska seeked to realize these intellectual attitudes working at the Lithuanian daily “Vilniaus zinios” in 1908 and especially editing the journal “Visuomene” (1910–1911 for the Lithuanian leftist intelligentsia. Birziska’s journalistic activities and his early intellectual biography carried features of specific cultural liberalism that was characteristic to the entire group of multinational intelligentsia in Vilnius before the First World War (Michal Römer, Tadeusz Wróblewski, Anton and Ivan Luckievich, Uriah Katzenelenbogen, and others.

  6. Establishment and evolution of the radiation risk concept for the man and human population in the 20th century

    International Nuclear Information System (INIS)

    The concept of radiation risk (RR) is the main basis for human protection from the harmful effect of ionizing radiation. It concerns the expected unfavorable health effects upon the irradiated person and probably upon his/her progeny. The early period of the history of RR evaluation was grounded on the assessment of acute skin reactions (erythema, epilation, dermatitis, ulceration) and on the measures (erythema dose) taken to diminish them. The second period covers the appraisal, based on estimation of different somatic effects and expected heredity ( genetic effects). They could be avoided if irradiation does not exceed the maximum permissible dose - the concept of zero RR. The current (third) period estimates both irradiation effects: deterministic effects that have a dose-related threshold and stochastic non-threshold effects. The ultimate goal of radiation protection is to exclude all deterministic effects and to diminish probability of stochastic effects (carcinogenesis and heredity effects) down to an acceptable level. Seven postulates describe the modern concept of RR for the man and human population: globalization irreversibility, accumulation, non-threshold harm, stochastic, non-specificity and acceptance of the risk

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

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

    Directory of Open Access Journals (Sweden)

    Meyer-Kalkus Reinhart

    2015-01-01

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

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

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

  17. Hyperdisease in the late Pleistocene: validation of an early 20th century hypothesis

    The hypothesis of disease-related large mammal extinction has new support. A unique pathologic zone of resorption was first noticed in a Hiscock Mammut americanum metacarpal. The pathognomonic zone of resorption was present in fifty-nine (52%) of 113 skeletons with feet available for examination. Metacarpals and metatarsals were most commonly affected. Associated rib periosteal reaction is highly suggestive of tuberculosis and the foot lesions were identical to that documented in Bison as pathognomonic for tuberculosis. Recognizing that only a portion of animals infected by infectious tuberculosis develop bone involvement, the high frequency of the pathology in M. americanum suggests that tuberculosis was not simply endemic, but actually pandemic, a hyperdisease. Pandemic tuberculosis was one of several probable factors contributing to mastodon extinction.

    This paper discusses how Spain’s urban housing markets reacted to the farreaching changes that affected the demand for dwellings during the first phase of the rural-urban transition process. To this end, we construct a new hedonic index of real housing prices and assemble a cross-regional panel dataset of price fundamentals. The results of our econometric analysis suggest that urban housing markets did not face supply constraints and responded swiftly to the growing demand for accommodation. ...

By studying the origin of constitutionalism in China and Japan, my dissertation reexamines the idea that “limited government” is the core of modern constitutionalism. I argue that constitutionalism, as it was introduced in Meiji Japan and late Qing China, focused on strengthening the gover...

  20. The relative contributions of radiative forcing and internal climate variability to the late 20th Century winter drying of the Mediterranean region

    The roles of anthropogenic climate change and internal climate variability in causing the Mediterranean region's late 20th Century extended winter drying trend are examined using 19 coupled models from the Intergovernmental Panel on Climate Change Fourth Assessment Report. The observed drying was influenced by the robust positive trend in the North Atlantic Oscillation (NAO) from the 1960s to the 1990s. Model simulations and observations are used to assess the probable relative roles of radiative forcing, and internal variability in explaining the circulation trend that drove much of the precipitation change. Using the multi-model ensemble we assess how well the models can produce multidecadal trends of realistic magnitude, and apply signal-to-noise maximizing EOF analysis to obtain a best estimate of the models' (mean) sea-level pressure (SLP) and precipitation responses to changes in radiative forcing. The observed SLP and Mediterranean precipitation fields are regressed onto the timeseries associated with the models' externally forced pattern and the implied linear trends in both fields between 1960 and 1999 are calculated. It is concluded that the radiatively forced trends are a small fraction of the total observed trends. Instead it is argued that the robust trends in the observed NAO and Mediterranean rainfall during this period were largely due to multidecadal internal variability with a small contribution from the external forcing. Differences between the observed and NAO-associated precipitation trends are consistent with those expected as a response to radiative forcing. The radiatively forced trends in circulation and precipitation are expected to strengthen in the current century and this study highlights the importance of their contribution to future precipitation changes in the region.

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

The temporal trends show constant incidence during endemic periods, interrupted by epidemic events. Four epidemic events during the last century occurred in circumstances of serious social disturbances and were caused by serogroups A (the first two, A and C, and B and C, respectively. Seasonal variations involved aggravation during autumn and winter throughout the entire century. Geographic distribution followed the displacement of the poor population in the urban territory. Age and gender distribution remained unaltered during all the endemic periods, showing an increased risk associated with younger age. The epidemic periods (except for the last showed major alterations in age and gender distribution, with an increased risk among young people and youth adults and occurrence in all age brackets.

Pero la emigración ya había provocado un estrangulamiento irreparable en las edades activas y de procreación, un fuerte descenso de la natalidad acentuado por la caída de la fecundidad posteriormente y un profundo envejecimiento. Por otra parte, la retención de los efectivos jóvenes y adultos en sus lugares de origen, junto a otros factores, incrementaron el paro hasta niveles desconocidos, si bien es un fenómeno que se ha conseguido paliar en buena medida en los últimos años del siglo. El futuro se presenta incierto, pues aunque no existe ningún núcleo abandonado, el envejecimiento, la baja natalidad y el paro están hipotecando el desarrollo endógeno de los núcleos rurales de la región.Summary: Along the second half of the 20th century the deepest transformations of the regional history have been produced so much by factors exogenous as endogenous of every kind. It has passed of an agrarian economy of subsistence to a competitive economy of the services and of the knowledge, what has supposed enormous excesses of agrarian unemployment to the end of century. Surplus that enlarged the great volume of emigrant population of the sixties and seventy that supposed the 40% of the regional population. Nevertheless, from beginnings of the eighty, the population is being stabilized. But the emigration already had caused an irreparable strangulation in the active ages and of procreation and a strong descent of the birthrate accentuated by the fall of the fertility and a deep aging. On the other hand, the retention of the young and adult population in its places of origin, next to other factors, it has increased the unemployment to unknown levels, though is a phenomenon that has managed to alleviate itself in good measure in recent years of the century. The future is presented uncertain, therefore although no nucleus abandoned exists, the aging, the low birthrate and the unemployment are mortgaging the endogenous development of the rural nuclei of the region.

    Full Text Available The article deals with the history of operation of Russia’s first railway ferry and the process of bridge construction across the lower Volga streamflows at Ryazan-Ural (now Volga railway line in Saratov, Stalingrad (Volgograd and Astrakhan. River railway ferries “Saratovskaya pereprava” and “Saratovsky ledokol” were built in 1894 in England and water crafts “Vtoraya pereprava” (1909 and “Stalin” (1926 were floated out in Volga in Nizhny Novgorod, from the Sormov plant. As a rule, the organization of transportations by means of steam locomotives and waggons through Volga during the first half of the 20th century preceded the construction of capital metal railway bridges, such as Astrakhan (1909 and Saratov (1935, and also a combined railway-automobile bridge through the Volga (Stalingrad Hydro-Electric Power Station (1961. The article is devoted not only to the technical features of ferries, bridges, but their efficient use in peace time and war time. So, the carrying capacity of the Saratov railway ferry increased in more than three times from 1907 to 1916. The Ryazan-Ural railway ferries were actively used by new Bolshevist regime. After the railroad construction on the left bank of Volga in autumn and winter of 1941, railway ferries “Stalin” and “Saratovskaya pereprava” were used for the carriage of military trains and population evacuation from the western bank of Volga. The author describes one of the most heroic and tragic facts in the history of Stalingrad battle using the example of the special operation railway ferry flooding and its consequent reconstruction.

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

  12. Studying in-between spaces of the Danish primary and secondary school as spaces of and in transition in the late 20th century

    DEFF Research Database (Denmark)

    Rasmussen, Lisa Rosén

    This paper analyzes the history of school corridors, walking areas, entrance halls and stairwells in the Danish primary and lower secondary school from 1970 and up till now. The paper uses the notion of transitory spaces to explore these in-betweens as spaces of and in transition. Spaces of transition in the sense of: being a space for moving across or moving between different contexts. Spaces in transition in the sense that: perceptions, uses and materiality of it change over time. A large corpus of written and visual material together with interviews and school visits is analyzed to see how in-between spaces come into being through specific attention to their danger and potential, but also in relation to the perception and construction of classrooms and school layout. In this the alteration of the in-between spaces pulls together important dynamics in the formation of the Danish primary and lower secondary school in the late 20th century, closely linked to the overall transformation of school life and its displaced material and discursive becoming as it is. The analysis is inspired by works of Karen Barad (2003, 2007) and Nigel Thrift (2006) and shows how the notion of the in-between spaces has taken shape in complex material-discursive intra-actions related to shifting concerns about the vulnerable and yet potential child as well as through available building materials, architectural designs and the number and organization of pupils’ bodies. By using this approach and working through the empirical material the analysis also points to possible ways to think the notion of transitory spaces as such.

    2006-12-01

    Full Text Available The article handles general developments and changes in book trade which took place in Estonia during the second half of the 19th century. The aim is to show the formation of bookshops trading with Estonian books and to analyse the activities of Estonian booksellers.The survey is based on the research literature and on the master thesis by Signe Jantson “Raamatukaubandus Eestis aastatel 1850–1917: raamatukauplused ja nende omanikud” (Book trade in Estonia 1850–1917: bookshops and their owners [9]. In this study great importance wasattached to the national and social origin of bookshop owners and their activities. Up to the middle of the 19th century the book production and dissemination in Estonia was in the hands of Baltic German entrepreneurs and depended on the political and economic developments not only in Russia but also in Germany. In the middle of the 19th century there were only 5 bookshops in Estonia located in bigger towns – Tallinn and Tartu. In 1870 the number of bookshops reached 13. The greater ascent can be noticed in the last decade of the period – 1870–1880 when 20 new bookshops were opened. In 1867 Heinrich Laakmann, a German origin publisher and the printing shop owner opened the first bookshop in Tartu to sell Estonian language books. The economic and political reforms as well as the national awakening movement favoured the engagement of Estonians in the sphere of book production and dissemination. Increasing publishing of Estonian language books enabled the development of trade. At the end of the national awakening period most of the bookshop owners were already of Estonian origin. Since 1870ies the number of Estonian bookshops started to grow and at the end of the 19th century they outnumbered German and Russian shops. In all over Europe book trade concentrated into the big cities (in the case of Estonia in Tallinn and Tartu, but bookshops were opened also in the rural area (small towns and villages. Altogether 263 bookshops were founded in the second half of the 19th and at the beginning of the 20th century and 283 persons became bookshop owners (at least for some years. These figures allow to conclude that book trade was a popular sphere of activity. The most intensive was foundation of bookshops during 1898–1904. Legally it was not difficult to get a permission to open a bookshop but only few shops (31% operated more than ten years; most often was that small shops operated up to five years. Trading with books did not guarantee sufficient income and the bookshop owners were often engaged in other spheres, mainly in book production and publishing. Majority of the Estonian origin bookshop owners derived from the peasant families and made up the first generation in book trade business. The newcomers had not enough education nor experience in the field. The most important achievement can be seen in the fact that bookshops were opened in all over Estonia that guaranteed dissemination of Estonian language books to all stratums of the society.

    Full Text Available Durante o século XX, o comércio internacional de peles foi responsável pelo abate de milhões de mamíferos e répteis na Amazônia. Negociadas no regime de comércio fluvial e aviamento, as peles seguiam dos portos e seringais, localizados no interior, para as casas aviadoras e exportadoras de Manaus e [...] Belém, de onde eram exportadas principalmente para os Estados Unidos, a Europa e o sul brasileiro. Neste artigo, analisamos documentos fiscais inéditos liberados pelo extinto império econômico do aviamento - a empresa J. G. Araujo -, bem como periódicos da Associação Comercial do Amazonas e os registros portuários da Manáos Harbour Ltd. O comércio internacional de peles silvestres intensificou-se imediatamente após a crise da borracha (1912) e atingiu seu auge entre 1935 e 1946, com o pico durante a Segunda Guerra Mundial. O segundo pico ocorreu na década de 1960, principal e ironicamente logo após a publicação da Lei de Proteção à Fauna (1967). Ao longo do período que antecedeu a aprovação da Convenção sobre o Comércio Internacional de Espécies Ameaçadas (CITES), em 1973-1975, não houve depreciação significativa no preço ou na demanda internacional por peles silvestres, sugerindo um esforço de caça constante e intenso por quase meio século. Abstract in english Throughout the 20th century, an international trade in animal hides resulted in the slaughter of millions of mammals and reptiles in the Amazon. Animal hides were purchased from extractivists through a network of traveling river merchants in a regime of debt peonage known as aviamento, carried from [...] trade posts in the hinterlands to warehouses in Manaus and Belém, and then exported to the United States, Europe and southern Brazil. Here we analyze previously unpublished shipping invoices from the famous merchant empire of J. G. Araujo as well as public port registries and commercial statistics from Manaus (Manáos Harbour Ltd., Associação Comercial do Amazonas). The international trade in Amazonian animal hides intensified immediately after the 1912 crash in rubber prices and spiked between 1935 and 1946, with a peak during World War II. The second spike occurred in the 1960s, mainly after the passage of Brazil's 1967 "Wild Animal Protection Law" intended to halt this trade. Throughout the period leading up to the adoption of the Convention on International Trade in Endangered Species (CITES) in 1973-1975, there was no significant depreciation in the price or international demand for animal skins, suggesting constant and intense hunting effort for nearly half a century.

    The study of the health/disease/healthcare process from the socio-medical aspect is the field of the medical anthropology. In Mexico, this medical specialty had its origins at the end of the 19th century. Since then, many educational reforms occurred associated to the political processes and the recognition and better understanding of Mexican pluricultural society; allowing expansion, diversification and consolidation of medical anthropology as an specialty. This review presents the historical evolution of the academic courses on this field, the educators that influenced its consolidation, and the current situation of the available academic programs on medical anthropology. The diversity of specialties from those health sciences that are associated to medical anthropology is emphasized. PMID:21072457

    2011-05-01

    Full Text Available This paper aims at retracing the important phases of migrations in the alpine regions and the Jura from the Middle Ages up to the middle of the 20th century. Migration has always functioned as a necessary complement to the resources of the inhabitants of the upland regions and it increases when the economic disparity with the lowlands becomes more marked. A striking characteristic of such migration is the great diversity that can be observed, since not only the destinations of the migrants varied from community to community, but also different forms of mobility coexisted within the same territory. Migration might be seasonal, pluriannual, lifelong or even definitive. It is also notable that the various types of migration can be observed to be part of a plurisecular tradition, apart from some significant exceptions, such as the emigration of the Walser, enforced migrations and the new types of migration as from the second half of the nineteenth century. The mobility of part of the population was also a consequence of modifications deriving from changes in the prevalent type of production (animal husbandry instead of the cultivation of cereals, as well as from demographic factors. In addition to these factors one can observe the role played by political institutions throughout the period under study: seigneurial power in the Middle Ages, the communal and cantonal instances until the second half of the nineteenth century, and afterwards the federal authorities.Cette contribution vise à montrer les grandes phases des mouvements migratoires du Moyen Age au milieu du XXe siècle dans les mondes alpin et jurassien suisses. La migration a toujours été une complémentarité nécessaire aux ressources de la montagne, et elle s'amplifie lorsque les disparités économiques avec le plat pays s'accroissent. Elle se caractérise par une forte diversité, puisque non seulement les destinations et les aires d'établissement des migrants peuvent varier fortement d'une commune à l'autre, mais aussi parce qu'au sein d'un même territoire ont toujours coexisté des formes différentes de mobilité, saisonnières, pluriannuelles, viagères ou définitives. Un aspect remarquable de ces types de migration est qu’ils s'inscrivent dans une très longue tradition pluriséculaire, avec quelques exceptions notables, ainsi les migrations des Walser, les migrations forcées et les nouvelles formes de la migration dès la seconde moitié du XIXe siècle. La mobilité est imposée aussi par les modifications des formes prévalantes de production (élevage plutôt qu'emblavures, de même que par les facteurs démographiques. A ces facteurs s'ajoute celui du rôle des institutions politiques tout au long de la période étudiée, seigneuriales au Moyen Age, communales et cantonales jusque dans la seconde moitié du XIXe siècle, puis fédérales.

  19. Dangerous and/or potential spaces. Securing the in-between in Danish primary and secondary schools in the late 20th century

    DEFF Research Database (Denmark)

    Rasmussen, Lisa Rosén

    The alterations of entrance halls, walking areas, stairways and schoolyards pull together important aspects of the formation of the Danish primary and lower secondary school in the late 20th century. On the one hand these in-between spaces can be seen as shaped by considerations of the child’s well-being as well as by safety legislation, and on the other hand their potentials as learning areas have been pointed out, they have been utilized for teaching purposes and optimized according to the latest didactics. These spaces which to a large extent have been overlooked as can be seen – in the terminology of Werner and Zimmermann’s histoire croisée (2006) – as important intersection points of entangled histories that fuel the changing understandings of what school, school life and school pupils are all about. This paper will explore how these in-between spaces at Danish schools have taken shape in complex material-discursive intra-actions between architects’ design of new school buildings, everyday furnishing andshifting concerns about the vulnerable and yet potential child. The paper will also look into the intra-actions between the physical layout of the schools and the increased focus on how to enhance learning with its altered connections between playing and learning. The analysis will work through notions of space, potentiality and material-discursive intra-activity inspired by works of Nigel Thrift (2006), Brian Massumi (2002) and Karen Barad (2003, 2007). The paper will concentrate on two examples from schools in the 1970s and the 2000s, respectively. Empirically, the paper will draw on material generated for the project “Schools in Denmark: A History of Everyday Life, Conditions, and Visions over 500 Years” (De Coninck-Smith et al. 2015) and include sources such as pedagogical journals, architects’ magazines, newspaper articles, reports from conferences and school developments, photographs, observations from school visits and from architects’, municipalities’ and schools’ digital platforms.

    Full Text Available It is very important to comprehend the climate variations in the vast regions of Central Plains of China. Current knowledge about climate changes of the past few hundred years in this region is primarily based on historical documents, and lack of evidences from the natural archives. However, these documents had somewhat artificially effects caused by the recorders, and not sufficient to fully understand natural climatic changes. In this paper, based on a significant correlation between the tree-ring width of Chinese Pine and observed instrumental data in the Mt. Yaoshan, China, we formulated a transfer function to reconstruct the mean minimum temperature (MMinT from the previous December to the current June (Tmin_DJ for the period 1873–2011. The reconstruction explained 39.8% of the instrumental variance during the calibration period of 1958–2011. High Tmin_DJ intervals with values greater than the 139 year average occurred in 1932–1965 and 1976–2006. The intervals 1878–1894 and 1906–1931 experienced a Tmin_DJ lower than the 139 year average. The ten highest Tmin_DJ years occurred after the 1950s, especially after 1996. A distinct upward trend in the Tmin_DJ series beginning in the 1910s was apparent, and the highest value occurred around 2000. The 20th-century warming signal was captured well by the Yaoshan Tmin_DJ temperature reconstruction, indicating that the temperature rise in the sensitive Central Plains of China region reflected the global temperature change. The Tmin_DJ reconstruction also matched several other temperature series in China with similar warm-cold patterns. The distinct spatial correlation between both observed and reconstructed series and CRU TS3.10 grid data indicates that our results may represent Tmin_DJ changes on a larger scale. The spatial correlation with sea surface temperature (SST indicated that observed and reconstructed Tmin_DJ temperatures in the Mt. Yaoshan are closely linked to the West Pacific, Indian and North Atlantic Oceans as well as El Niño-Southern Oscillation (ENSO.

  1. The place occupied by early measurement (20th minute) of the thyroid uptake of sup(99m)Tc pertechnetate in thyroid pathology

    International Nuclear Information System (INIS)

    The place occupied by early measurement (20th minute) of the thyroid uptake of sup(99m)Tc pertechnetate is situated for different types of thyroid condition (hypo-, normo- and hyperthyroidism). The use of technetium is simple in practice because only the cervical and crural radioactivity measurements are required. Like all simplified methods it involves risks of errors but lends itself to systematic routine use. The practical advantages of this isotope, which in view of its short half-life appears with iodine 123 as the nearly ideal tracer for thyroid exploration at present are outlined. The thyroid gland can be studied both functionally and scintigraphically at the cost of minimum irradiation, which is a great advantage. The fact that a number of data may be obtained in less than an hour (including scintigraphy) is a particularly valuable asset. However the method has its limits. For example a diagnosis of hyper or hypothyroidism based on the technetium uptake at the 20th minute alone is out of the question. A zero uptake may be observed in the presence of Basedow's disease or conversely a high uptake in hypo- or euthyroid cases. Discrimination is satisfactory between hyper and euthyroid but not between eu- and hypothyroid subjects. Technological progress however promises a routine use of 123 I and 99mTc together, the two isotopes serving to explore two different phases of the thyroid metabolism

    There is substantial evidence that soil thermal dynamics are changing in terrestrial ecosystems of the Northern Hemisphere and that these dynamics have implications for the exchange of carbon between terrestrial ecosystems and the atmosphere. To date, large-scale biogeochemical models have been slow to incorporate the effects of soil thermal dynamics on processes that affect carbon exchange with the atmosphere. In this study we incorporated a soil thermal module (STM), appropriate to both permafrost and non-permafrost soils, into a large-scale ecosystem model, version 5.0 of the Terrestrial Ecosystem Model (TEM). We then compared observed regional and seasonal patterns of atmospheric CO2 to simulations of carbon dynamics for terrestrial ecosystems north of 30??N between TEM 5.0 and an earlier version of TEM (version 4.2) that lacked a STM. The timing of the draw-down of atmospheric CO2 at the start of the growing season and the degree of draw-down during the growing season were substantially improved by the consideration of soil thermal dynamics. Both versions of TEM indicate that climate variability and change promoted the loss of carbon from temperate ecosystems during the first half of the 20th century, and promoted carbon storage during the second half of the century. The results of the simulations by TEM suggest that land-use change in temperate latitudes (30-60??N) plays a stronger role than climate change in driving trends for increased uptake of carbon in extratropical terrestrial ecosystems (30-90??N) during the recent decades. In the 1980s the TEM 5.0 simulation estimated that extratropical terrestrial ecosystems stored 0.55 Pg C yr-1. with 0.24 Pg C yr-1 in North America and 0.31 Pg C yr-1 in northern Eurasia. From 1990 through 1995 the model simulated that these ecosystems stored 0.90 Pg C yr-1, with 0.27 Pg C yr-1 stored in North America and 0.63 Pg C yr-1 stored in northern Eurasia. Thus, in comparison to the 1980s, simulated net carbon storage in the 1990s was enhanced by an additional 0.35 Pg C yr-1 in extratropical terrestrial ecosystems, with most of the additional storage in northern Eurasia. The carbon storage simulated by TEM 5.0 in the 1980s and 1990s was lower than estimates based on other methodologies, including estimates by atmospheric inversion models and remote sensing and inventory analyses. This suggests that other issues besides the role of soil thermal dynamics may be responsible, in part, for the temporal and spatial dynamics of carbon storage of extratropical terrestrial ecosystems. In conclusion, the consideration of soil thermal dynamics and terrestrial cryospheric processes in modeling the global carbon cycle has helped to reduce biases in the simulation of the seasonality of carbon dynamics of extratropical terrestrial ecosystems. This progress should lead to an enhanced ability to clarify the role of other issues that influence carbon dynamics in terrestrial regions that experience seasonal freezing and thawing of soil.

    Full Text Available The topic of this article is the literary discourse of Young Estonia; its relations with other important Estonian literary discourses from the beginning of the 20th century, and its relations with colonial cultural discourse. First, I give an overview of the basic positions of the Young Estonians’ literary discourse, the main shapers of which were Friedebert Tuglas, Gustav Suits, later on Johannes Semper as well. Next, I present the basic principles of three Estonian literary discourses from the beginning of the 20th century, which were also important to the Young Estonians: nationalist-naturalistic (close-to-life; socialist/ class-based, and 20th century modernist. The Young Estonians began as nationalists and/or socialists. During the formation of Young Estonia’s discourse at the end of the first and beginning of the second decade of the 20th century, 20th century modernism began, which the Young Estonians regarded first and foremost with irony. The Young Estonians’ literary discourse is a mixture of aestheticism, decadence, symbolism, romanticism, and classicism. The point of departure for the Young Estonian approach to literature was eurocentrism. They took a superior and negative view of existing Estonian literature, which they regarded as having fallen drastically behind Europe. Since it was unable to build on its own foundation, it had to borrow from Europe. The discourse’s understandings of cultural values – theory, reading, knowledge, ready-made culture, derive from the centrality of the dynamic of borrowing. New culture could be created freely, without the support of previous local tradition; it was to be an elite culture, while the writer remained an individualist. Literature was to follow the principle of art for art’s sake; aesthetics and the form of the work of art were basic criteria. The formal ideals of the work of art were classicist: unity, integrity (wholeness, harmony, order, logic, etc. Thirdly, I outline the basic positions of colonial thinking about culture, and compare the Young Estonian approaches to literature with colonial thought. The foundation of colonialism is eurocentrism: if Europe is the core; everything else belongs to the periphery, and regarded from the outset as of lesser inherent worth: colonialism is characterized by a superior and negative attitude toward local culture. The colonizing culture interprets its own values and experiences as universals; these are congruent with the outlines of what is deemed to be ”European” culture. The mission of colonialism is to bring the periphery into the sphere of influence of the enlightened core. Though colonial thinking does not commit itself to any specific artistic movement or style, its most important tenet with regard to evaluating art is classicist, emphasizing enduring values and good ”handiwork”. The bases for the creation of colonial culture are ready-made models and categories, and the outcome of colonization is culture constructed according to a model. The outcome of the analysis is that the Young Estonian way of thinking is in close consonance with the colonial way of thinking. Those attitudes that Young Estonians did not adopt, or those they relinquished and discarded, are in opposition to it. My own basic claim is that the Young Estonians unconsciously carried a colonial way of thinking, and that they might be considered to be self-colonizers.

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

Desde la perspectiva de la arqueología histórica, se propone reconstruir las historias tafonómicas del conjunto artefactual de superficie de es [...] te "Ghost town". Los procesos tafonómicos son analizados desde la escala del artefacto y su distribución espacial considerando múltiples variables (tamaño, alteración térmica, meteorización, topografía del terreno, pisoteo, actividades antrópicas y animales cavadores). Se utiliza sistema de información geográfica (SIG) para interrelacionar las diferentes variables de análisis y evaluar la incidencia de los distintos agentes tafonómicos en las características y distribución de los materiales. Esperamos poder comprender la dinámica de formación que afectó al sitio y generar expectativas para contextos tafonómicos similares de la región. Abstract in english The Mariano Miró archaeological site (Chapaleufú Department, La Pampa Province, Argentina) was a town of nearly 500 inhabitants, founded in 1901 and abandoned in 1911. From the Historical Archaeology perspective, this paper aims to reconstruct the taphonomic histories of surface artifact assemblages [...] from the Mariano Miró ghost town. We analyze taphonomic processes at both the artifact and the assemblage level, considering multiple variables including size, thermal alteration, weathering, site topography, trampling, anthropic activities and burrowing animal activities. We use GIS to interrelate the selected variables and assess the roles of various taphonomic agents in shaping the characteristics and distributions of materials at Mariano Miró. The information pertaining to formation processes obtained from Mariano Miró is potentially useful for generating expectations for and understanding other sites in the region that exhibit similar taphonomic conditions.

Resultados: en las cuatro primeras décadas estudiadas de 1910 a 1949, la mortalidad materna en Cuba mostró un descenso de 51,0 %, desde tasas de 493,4 por 100 000 nacidos vivos en la década 1910-1919 a tasas de 242,2 en la década de 1940-1949, en una época en la que no existían los antibióticos ni los bancos de sangre, ni tampoco se había generalizado la atención prenatal. Estas cifras no deben considerarse demasiado elevadas en aquellos años en un país subdesarrollado. El notable descenso de una década a otra, es testimonio de la lucha contra sus principales causas, llevada a cabo por profesores y discípulos, por el desarrollo obtenido por las mujeres, las facilidades del transporte, la disponibilidad de médicos, enfermeras y comadronas y el alcance obtenido por los medios masivos de comunicación como la radio y la prensa escrita. Se muestran los descensos obtenidos en las principales causas de muerte como la infección puerperal, las muertes por hemorragia y las debidas a eclampsia convulsiva y preclampsia. Conclusiones: el comportamiento de las cifras analizadas no es una simple coincidencia con la aplicación en Cuba de los nuevos cambios en la medicina en general, y en la atención materna en particular, sino también la influencia que tuvo en la salud el desarrollo económico y social de la nación.Objective: to describe cases of maternal deaths between 1910 and 1949. Methods: descriptive and documentary research. Results: in the first four decades surveyed from 1910 to 1949, maternal mortality in Cuba showed a decrease of 51.0 % from rates of 493.4 per 100 000 live births from 1910 to 1919 at a rate of 242.2 during 1940-1949, at a time when there were no antibiotics or blood banks, nor was widespread prenatal care. These figures should not be considered as too high in those years in an underdeveloped country. The sharp decline during these decades is an evidence of the fight against the main causes, conducted by teachers and pupils, by the work achieved by women, the availability of doctors, nurses, midwives and means of transportation, and the extended scope of mass media such as radio and print media. The declines in the leading causes of death as puerperal infection, bleeding and deaths due to preeclampsia and convulsive eclampsia are shown in the study. Conclusions: the behavior of the data examined is not a mere coincidence with the implementation of the new changes in medical general practice in general in Cuba, and particularly maternal care, but also influence it had on the health and social-economic development of the whole nation.

  9. Major 20th century changes of water-soluble humic-like substances (HULISWS) aerosol over Europe inferred from Alpine ice cores

    Using a newly developed method dedicated to measurements of water-soluble humic-like substances (HULISWS) in atmospheric aerosol samples, the carbon mass quantification of HULISWS in an Alpine ice core is achieved for the first time. The method is based on the extraction of HULISWS with a weak anion-exchanger resin and the subsequent quantification of the extracted carbon fraction with a total organic carbon (TOC) analyzer. Measurements were performed along a Col du Dôme (4250 m above sea level, French Alps) ice core covering the 1920-2004 time period. The HULISWS concentrations exhibit a well-marked seasonal cycle with winter minima close to 7 ppbC and summer maxima ranging between 10 and 50 ppbC. Whereas the winter HULISWS concentrations remained unchanged over the twentieth century, the summer concentrations increased from 20 ppbC prior to the Second World War to 35 ppbC in the 1970-1990s. These different trends reflect the different types of HULISWS sources in winter and summer. HULISWS are mainly primarily emitted by domestic wood burning in winter and secondary in summer being produced from biogenic precursors. For unknown reason, the HULISWS signal is found to be unusual in ice samples corresponding to World War II.

Starting from the re-opening of the university, the growth of the population in the city has been directly correlated with the growth of the university and its student body (Kruus, 1927. In 2010 the collective body of the university constituted approximately 1/5 of the registered population (Tartu City Forum, 2010. The anchor institution is a driver of economic growth, a real estate developer and a service provider (Harkavy et al., 2009. The University of Tartu and Tartu University Hospital known as Estonian Meds and Eds are one of the key factors of the favorable economic climate since the two medical and educational institutions concur in providing health care, quality of life, amenity and highly educated labor for the community. In the 21st century Tartu University Hospital has become one of the anchor institutions of Tartu and South Estonian Region, having a direct impact on the City and its economic growth.

    Full Text Available The territory of the former Yugoslavia (within all of its structures and forms during the second half of the 20? century - from FPRY, SFRY, FRY, to Serbia and Montenegro was the subject of more or less intensive external and internal migrations. The first larger wave of emigration occurred immediately after the end of World War II, mostly due to the political events in the country that concerned ideological orientation of national-liberation war winners. In most cases, the furthest destinations of these emigrants were overseas countries. The remoteness of the new "homelands", among other reasons, made these relocations permanent. In the beginning of 1960's a new wave of mass immigrations occurred due to the "liberation" of Yugoslavia's economy and politics, and the need of labor force in the countries of Western Europe. These were the economic, so-called labor-migrations that were supposed to have a temporary character. During the period of 1964-1973, Yugoslav citizens living in Western European countries numbered approximately one million and one hundred thousand, out of which two-fifths were Serbs. In the mid 1970's, a migration trend seemed to slightly decline, only to increase again in the 1980's, and especially during the 1990's, however with the new socio-economic-political background and different characteristics than the preceding ones. It could be argued though, that these new migrations of Yugoslav citizens sum up all the characteristics of the preceding ones, being, at the same time, very dramatic in nature considering that the migrations were most of the time the only available option for emigrants. In general, these migrations are characterized by relocation of whole families, absence of a long-term plan considering the future (duration of stay, return to the home country, money investment in the home country, and relatively high although diverse educational level. Actually, based on comparison between censuses in 1981 and 1991, it is evident that in 1991 more people with a high school diploma gymnasium, higher and academic education have left the country than in 1981. The available data from 2001 census consist only of a relative number of Yugoslav citizens living abroad, around 400,000, but this number does not include citizens from Kosovo and Metohija, or Montenegro. Only when the final census data come out, will it be possible to analyze and compare migrations from 1991 -2001, although considering census gathering and its limitations, it is clear that many trends will remain hidden.

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

Friendship opens up an ethical way to selfovercoming, in which each human being, accompanied by another, has the opportunity to reach beyond his or hers own limitations. The article confronts this interpretation of friendship with Nietzsche’s vision of the superman and shows the relevance of the ethics of friendship to philosophical ethics in the 20th.

La amistad abre un camino ético hacia la autosuperación, en el que cada ser humano, acompañado por otro, tiene la oportunidad de llegar más allá de sus propias limitaciones. El artículo confronta esta interpretación con la visión nietzscheana del superhombre y muestra la relevancia de la ética de la amistad para dos representantes de la ética filosófica del siglo xx, Hans-Georg Gadamer y Emmanuel Lévinas.

    Full Text Available The classic risk factors for developing coronary heart disease (CHD explain less than 50% of the decrease in mortality observed since 1950. The transition currently under way, from the degenerative to the infectious-inflammatory paradigm, requires a new causal interpretation of temporal trends. The following is an ecological study based on data from the United States showing that in men and women an association between the age distribution of mortality due to influenza and pneumonia (I&P associated with the influenza pandemic in 1918-1919 in the 10-49-year age bracket and the distribution of CHD mortality from 1920 to 1985 in survivors from the corresponding birth cohorts. It further shows a significant negative correlation (r = -0.68, p = 0.042 between excess mortality from I&P accumulated in epidemics from 1931 to 1940 (used as indicator for persistent circulation of H1N1 virus combined with vulnerability to infection and the order of the beginning in the decline in CHD mortality in nine geographic divisions in the United States. In light of current biological knowledge, the data suggest that the 1918 influenza pandemic and the subsequent epidemics up to 1957 might have played a determinant role in the epidemic of CHD mortality registered in the 20th century.

    Full Text Available This paper has two main goals. The first is to review the context for studying infant mortality, which includes a review of the theoretical framework, the covariates used to examine mortality over the first 60 months of life, and the major findings of empirical studies. Second, the paper adds some new empirical evidence that comes from the longitudinal reconstitution of church registers of Bejsce parish, located in the south of Poland. This rich database allows for an analysis of mortality trends of cohorts born between the 18th and 20th centuries in the parish. The analysis includes a reconstruction of descriptive measures of infant and childhood mortality, and a hazard model of mortality over the first 60 months of life. The hazard model has been calculated for each cohort separately in order to demonstrate the change in the relative importance of analyzed factors during the process of mortality decline in the parish. Obtained mortality patterns are discussed with reference to the theoretical context presented in the first part of the paper.

    Full Text Available Comparar trajetórias políticas ao longo de um século supõe um esforço muito maior de esquecimento do que de memória. Tentarei aqui converter uma grande quantidade de matérias analíticas muito heterogêneas em algumas conjeturas "popperianas". Elas podem provir de qualquer parte e podem ser submetidas [...] à corroboração ou à refutação. Ou seja, trata-se de um processo inverso à tarefa estritamente acadêmica. Em certamedida, estou recomeçando "desde o zero" o meu trabalho. É verdade que a história democrática argentina, no século XX, é mais longa do que a brasileira. Todavia, essa diferença não invalida a comparação. Minha hipótese concisa é a seguinte: na política democrática brasileira, a dimensão institucional é dominante - as instituições, de fato, representam o lugar em que se dão as interações e em que os atores coletivos configuram-se. Em compensação, nessas instituições, a inclusão tanto social como política tem sido fraca. No entanto, no caso argentino, a dimensão inclusiva tem sido dominante, com o prejuízo indubitável da dimensão institucional. Na política democrática argentina, participaram "todos". Na política democrática brasileira até 1964, a estabilidade baseou-se na exclusão - por exemplo, das massas rurais. Estas hipóteses podem estar corretas ou erradas, mas, em qualquer caso, importa dizer que não as estabeleci ex nihilo, como vindas do nada, nem diacrônica, nem sincronicamente. Diacronicamente, porque a história do século XX sustenta-se, é obvio, na do XIX; sincronicamente, porque com certeza cada uma das hipóteses ou conjeturas que discuti aqui pode imbricar-se com os processos do próprio século XX, com os dramas, as lutas, as lideranças, os conflitos, as controvérsias, as gestões de governo, os períodos de depressão e de prosperidade e as esperanças, tudo, enfim, o que constitui a história desse século. Abstract in english Comparing political trajectories over the course of a century demands more forgetting than remembering. I will make an attempt here to convert a considerable amount of very heterogeneous analytical material into some "Popperian" conjectures. They may emerge from anywhere within and may be subjected [...] to corroboration or refutation. In other words, this process is precisely the reverse of the one that informs strictly academic tasks. To some extent, I begin my work "from scratch". It may be true that the history of democracy in Argentina is longer than that of Brazil. Nonetheless, this difference does not invalidate comparison. My concise hypothesis is the following: in Brazilian democratic politics, the institutional dimension prevails - institutions, in fact, represent the place in which interactions occur and collective actors take shape. In compensation, within these institutions, both social and political inclusion has been weak. However, in the Argentine case, the inclusive dimension has been dominant, in clear detriment to the one. In Argentine democratic politics, "everyone" was included. In Brazilian democratic politics until 1964, stability was based on exclusion - for example, the exclusion of the rural masses. These hypotheses may be correct or incorrect but in any case, it is important to emphasize that they have not been established ex nihilo, as if coming from nowhere and neither diachronic nor synchronic. Diachronic, insofar as the history of the 20th century is sustained, obviously, in the history of the preceding one; synchronic, because each of the hypotheses or conjectures discussed here are undeniably embedded in processes that are proper to the 20th century, its dramas, struggles, leaders, conflicts, controversies, political administrations, periods of depression and prosperity and hopes; in short, all that makes up the history of the century.

Décrypté naguère à travers certains poncifs assignés aux peuples méridionaux (irrationalité, pusillanimité, etc., le présumé conservatisme culinaire des Italiens, du Sud en particulier, y était perçu comme un syndrome quasi pathologique, devenant la cible des politiques sociales et de santé. Avec le temps, cette culture alimentaire « sans qualités » s’est vue amendée du stigmate de son origine puis ennoblie par la promotion du modèle de consommation dit méditerranéen. La déconstruction diachronique des lectures américaines et helvétiques des habitudes alimentaires des migrants italiens met en exergue, outre l’inversion de certaines catégories normatives, un rapport de (biopouvoir spécifique entre culture d’accueil et d’origine soulevant l’utilité d’une réflexion épistémologique sur la construction sociale actuelle de la santé et du goût « méditerranéens ».Dietary habits of Italians settled in the US and in Switzerland have been interested during the 20th century by a mutation of host society attitude, formerly hostile but now full of this gastronomic heritage. The presumed culinary conservatism of southern Italians, represented through classical clichés (irrationality, pusillanimity, etc., was diagnosed as a pathological-like syndrome and became in that sense a target for social and health policies. With the passing of time, this « propertiless » dietary culture lost the infamous marks of its origins and got ennobled by the promotion of the Mediterranean consumption model. The diachronic deconstruction of American and Swiss interpretations of Italian migrants dietary habits underline, besides the inversion of some normative categories, a specific relation of (biopower between host and native cultures. This analysis raises the interest of an epistemological reflexion about the current social construction of « Mediterranean » health and taste.

    Full Text Available Este estudio tiene como propósito mostrar desde una perspectiva histórico-ambiental, aspectos relacionados con las prácticas higienistas características de la ciudad de Cali durante la primera mitad del siglo XX. Se destacan algunos de los problemas centrales relacionados con esta urbe y con algunas [...] poblaciones aledañas, en un momento histórico en el que se presentaron graves dificultades concernientes al abastecimiento de agua, al sistema de desagüe urbano y a la organización de los servicios de higiene correspondientes a la limpieza pública, la recolección de residuos, y la situación de establecimientos insalubres. El estrecho vínculo existente entre el discurso higienista y la idea de progreso impulsó la ejecución de propuestas encaminadas al mejoramiento de la potabilidad del agua y la adopción de prácticas en las que este recurso se convirtió en elemento estratégico para la limpieza pública, doméstica y personal. La construcción del acueducto y el alcantarillado representó una vía de solución frente a los requerimientos propios del panorama citadino de comienzos de siglo, en el que resultaba prioritario responder al tema de la salubridad, al avance del crecimiento demográfico, industrial y urbano, y al logro de mejores condiciones de vida para la población.

Métodos: Entresacamos datos de la información recogida en diferentes publicaciones periódicas, de las memorias de algunos de los participantes y de las actas de los congresos. Resultados: Hemos obtenido notas de la reunión constitutiva de la Asociación Internacional y de sus dos congresos y luego de los veinticinco de la Sociedad. Extraemos, principalmente de las actas editadas por el secretario de la reunión, la asistencia de los urólogos españoles y su contribución con ponencias o comunicaciones así como la relevancia que han tenido al desempeñar cargos en el seno de la organización. Conclusiones: Desde 1907 la presencia de urólogos españoles tanto en la Asociación como en la Sociedad Internacional de Urología ha sido constante. En la primera mitad del siglo, años en los que nuestra Urología se encontraba en un periodo de consolidación, fueron los responsables de los principales servicios urológicos de los grandes hospitales del país los que podían transmitir su experiencia con un nivel y calidad equiparables a los del resto de los europeos. En la segunda, una vez recuperadas las naciones de los episodios bélicos, prosigue la actividad científica con una creciente aportación española conforme se extiende por todo el país la creación de los Hospitales de la Seguridad Social con servicios jerarquizados de Urología en los que se realiza el estudio y el análisis de sus casuísticas y se inician la investigación clínica y experimental, lo que permite que las comunicaciones españolas se incrementen de modo notable sobre todo en los congresos celebrados en poblaciones de habla castellana o en los europeos. Como consecuencia de su participación, en España se han desarrollado tres de los veinticinco congresos organizados en el siglo XX. La presencia española en los órganos rectores de la Sociedad se vio favorecida con la presidencia del profesor D. Salvador Gil Vernet por dos periodos consecutivos.

In the present study, 44 Anatolian skulls from two different eras, Byzantine (13th century) and contemporary (20th century), were investigated for morphology and location of the pterion. Sphenoparietal was the most common form, comprising 87.5% and 89.2% in the Byzantine and contemporary groups, respectively. The frequencies of the epipteric type of pterion were 6.25% and 3.6% in the Byzantine and contemporary groups, respectively. Measurements of the location of the pterion were made by using stainless steel calipers and Scion Image software. There were no significant differences in digital and manual measurements between the right and left sides of the skulls in both groups. However, the distance from the pterion to the inion was significantly greater in the manual measurements compared to the digital measurements. Anatomical variations of the pterion, which are of interest to anthropologists, forensic pathologists and surgeons, deserve further investigation in other populations from different geographical areas.

    Full Text Available The article presents statistical data on the publications of belles-lettres in Estonia in 1900–1940 – a period when the country developed into a modern European society and gained independence. The topic is treated in the context of book history, which uses publishing statistics to provide a broader context for individual case studies. The research on the quantity and share of translated literature in book production comes close to the statisticalsociological approach in translation history, characterised by Peeter Torop as one of the aspects of the study of translation culture. The statistical indicators have been elaborated on the basis of retrospective bibliographies and on the data, obtained from National Library of Estonia. The analysis includes the share of belles-lettres in book production, the balance of original works and translations, the changes in the quantity of translations during different decades and the share of source literatures. The Estonian statistics have been presented in comparison with corresponding data from Finland, which has been published in the collective monograph on Finnish translation history, issued in 2007. As the Finnish data is organized by decades, the same principle is used for statistics on Estonia. This approach corresponds generally to the political history of the two countries – both belonged to the Russian Empire during the first two decades of the 20th century and existed as independent states during the following two decades. Both nations had passed through the first stage in the development of literary culture, characterised by extensive publication of adaptations and free translations by the beginning of the century. Thus the share of original works started to increase and slightly exceeded the share  of  translations  in  E stonia  as  well  as  in  Finland.  The  selection  of  translated  works  in both countries was varied and their level was unstable. Despite the longstanding plans of developing translation culture in Finland, the choice of works was influenced by international acclaime and the activitiy of translators. The immaturity of Estonian publishing manifested itself, among other things, as inadeaquate paratexts of the translations. Due to the differences in historical development and cultural background, the structure of  source  literature s  of  translated  belle s-let tre s  in  the  two  countrie s  dif fered  in  many  ways – translating from the English language increased considerably in Finland, fending the traditional German and Scandinavian domination. The importance of translations of German literature, which maintained the leading role in Estonia, is a common feature of both countries. At the same time, the interest in Scandinavian literature only started to emerge in Estonia. The  translations  of  Rus sian  literature,  however,  were  much  more  numerous  in  E stonia  thanin Finland. In general, the period of 1900–1919 is characterised by a notable increase in the quantit y of translated belles-lettres as well as their uneveness. However, the growing number of translations provided greater diversity, introducing new authors, styles and trends.The existence of an independent Republic of Estonia (since 1918 opened utterly new perspectives for the development of national culture – for the first time it could be done without external control and using the Estonian language in all levels of administration and education. These circumstances fostered publishing, the demand for books was especially great during the first years after the War of Independence (1918–1920, later the declines and increases in book production were connected to the economic conditions. Belles-lettres formed about 20 per cent of the title production, which in turn was almost equally divided between original works and translations. In contrast to Estonia, the number of translations started to decrease in Finland in the 1930s due to economic and political factors, idealising conservative national values. Th

Durante los siglos XX y XXI el abordaje de esta enfermedad sufrió cambios paradigmáticos muy interesantes, pero principalmente estuvo influenciado por los descubrimientos relacionados con la segunda guerra mundial, la situación económi [...] ca mundial, el advenimiento de nuevas estrategias de control y el abordaje de la enfermedad por medio de la participación comunitaria y el sector de la salud. El propósito de este trabajo es presentar los cambios de paradigmas desde una óptica vertical o erradicación, a una horizontal o eliminación, y desde lo positivista cuantitativo a lo mixto, en el abordaje de la malaria en Guatemala. Se realiza una reseña histórica de la malaria y se discuten los aspectos bioéticos del uso del insecticida dicloro-difenil-tricloroetano a nivel mundial. En los países desarrollados fueron justificadas las intervenciones de erradicación con el rociamiento intradomiciliar del insecticida citado y completarlas con el diagnóstico y tratamiento de la malaria; la realidad en la mayoría de los países en vías de desarrollo, fue diferente, puesto que no pudieron mantener los programas de erradicación por problemas financieros, un ejemplo claro de iniquidad global. Guatemala en esta década trabaja en la fase de preeliminación-eliminación, con buenos resultados, lo que marca un cambio de paradigma e indica que las medidas contra la malaria deben ser horizontales y favorecer el trabajo intra e intersectorial. Abstract in english Malaria remains a world health problem. During the 20th and 21st centuries, the approach to this disease underwent very interesting paradigmatic changes, but they were influenced by breakthroughs derived from the Second World Wear, the international economic situations, the advent of new monitoring [...] strategies and the approach to the disease based on the community and the health sector involvement. The objective of this paper was to present changes in paradigms form a vertical perspective or eradication to a horizontal viewpoint or elimination, and from a quantitative positivist to a combined standpoint in addressing malaria in Guatemala. A historical account of malaria was made and the bioethical aspects of the use of dichlorodiphenyltrichloroethane worldwide were discussed. The eradicating interventions by using the insecticidal spraying of houses were backed up in the developed countries. This was supplemented with the diagnosis and treatment of malaria. However, the situation was different in most of the developing countries, since their financial restrictions did not make possible to keep the eradication programs, being a clear example of the global inequality. In the present decade, Guatemala is going through the pre-elimination-elimination phase and it works with good results, which is indicative of a change in paradigm and shows that actions against malaria should be horizontal in order to encourage the intrasectorial and the intersectorial work.

They concluded that the feeling of the racial consciousness, the need to integrate themselves with the nation and the desire for social mobility were the reasons that held the African Americans together through those associations. Thence, the "Black Press" tried to build a representation of black identity that emphasized the soccer resources, without forgetting moral matters as discipline, hygiene and order. The dissemination of the achievements of blacks in sports promoted a positive identity of black man in soccer, in accordance with the demands of that context: a sanitized and disciplined nation in accordance with the national project that understood soccer as a mean of positive expression of "Brazilianness".

The objective was to observe the continuity and regularity of the speech, the points of confrontation and symbolic dispute around the negotiation of the identity construction of "black" in the sport and identify, by means of the messages sent by those media outlets, the strategies of distinction used by the ethnic / racial group around the defense against negative representations or construction of positive representations of blacks in the emerging field of soccer. They concluded that the feeling of the racial consciousness, the need to integrate themselves with the nation and the desire for social mobility were the reasons that held the African Americans together through those associations. Thence, the "Black Press" tried to build a representation of black identity that emphasized the soccer resources, without forgetting moral matters as discipline, hygiene and order. The dissemination of the achievements of blacks in sports promoted a positive identity of black man in soccer, in accordance with the demands of that context: a sanitized and disciplined nation in accordance with the national project that understood soccer as a mean of positive expression of "Brazilianness".

  11. Dietary reconstruction and reservoir correction of 14C dates on bones from pagan and early Christian graves in Iceland : Proceedings of the 20th International Radiocarbon Conference

    In this study, ?13C and ?15N of bone samples from 83 skeletons (79 humans, 2 horses, and 2 dogs) excavated from pagan and early Christian graves from 21 localities in Iceland are used to reconstruct diet of the early settlers in Iceland and possible differences in diet depending on the distance between the excavation site and the seashore. We have radiocarbon dated 47 of these skeletons and used the carbon isotopic composition (?13C) to estimate and correct for the marine reservoir effect (the 14C difference between terrestrial and mixed marine organisms). The reservoir-corrected ages lie in the range of AD 780?1270 (68.2% probability). Reservoir age corrections were checked by comparing 14C dates of a horse (terrestrial diet), a dog (highly marine diet), and a human (mixed diet) from the same burial. The range in measured marine protein percentage in individual diet is from about 10% up to 55%, mostly depending on the geographical position (distance from the sea) of the excavation site. We had access to the skeleton (AAR-5908) of the Sk?lholt bishop P?ll J?nsson whose remains are enshrined at the Episcopal residence in Sk?lholt, southern Iceland. According to written sources, the bishop died in AD 1211. Using our dietary reconstruction, his bones were about 17% marine, which is within the range of human skeletons from the same area, and the reservoir-corrected calibrated 14C age of the skeleton is in accord with the historical date.

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

    In certain respects the situation of Marxism in the early 21st century has much in common with that in the late 19th century. In both cases Marxism is faced with a world in which the capitalist mode of production dominates. During what Hobsbawm called the ‘shorter 20th century’, the period from 1914 to 1990, world politics centered round the epochal struggle between capitalist and socialist economic systems, and that reality gave to Marxism a quite different character than in its first period...

  19. Turn of the century refueling: A review of innovations in early gasoline refueling methods and analogies for hydrogen

    International Nuclear Information System (INIS)

    During the first decades of the 20th century, a variety of gasoline refueling methods supported early US gasoline vehicles and successfully alleviated consumer concerns over refueling availability. The refueling methods employed included cans, barrels, home refueling outfits, parking garage refueling facilities, mobile stations, hand carts and curb pumps. Only after robust markets for gasoline vehicles had been firmly established did the gasoline service station become the dominant refueling method. The present study reviews this history and draws analogies with current and future efforts to introduce hydrogen as a fuel for vehicles. These comparisons hold no predictive power; however, there is heuristic value in an historical review of the first successful and large-scale introduction of a vehicle fuel. From an energy policy perspective, these comparisons reinforce the importance of a long-term and portfolio approach to support for technology development and innovation

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

    Wahl, T.; Calafat, F. M.; Luther, M. E.

    2013-12-01

    The seasonal cycle is an energetic component in the sea level spectrum and dominates the intra-annual sea level variability outside the semidiurnal and diurnal tidal bands in most regions. Changes in the annual or semi-annual amplitudes or phase lags have an immediate impact on marine coastal systems. Increases in the amplitudes or phase shifts towards the storm surge season may for instance exacerbate the risk of coastal flooding and/or beach erosion, and the ecological health of estuarine systems is also coupled to the seasonal sea level cycle. Here, we investigate the temporal variability of the seasonal harmonics along the US Gulf of Mexico (GOM) coastline using records from 13 tide gauges providing at least 30 years of data in total and at least 15 years for the period after 1990. The longest records go back to the early 20th century. Running Fourier analysis (with a window length of 5-years) is used to extract the seasonal harmonics from the observations. The resulting time series show a considerable decadal variability and no longer-term changes are found in the phase lags and the semi-annual amplitude. The amplitude of the dominating annual cycle in contrast shows a tendency towards higher values since the turn of the century at tide gauges in the eastern part of the GOM. This increase of up to more than 25% is found to be significant at the 90% confidence level for most tide gauges along the coastline of West Florida and at the 75% confidence level for virtually all stations in the eastern GOM (from Key West to Dauphin Island). Monthly mean sea level sub-series show that the changes are partly due to smaller values in the cold season but mostly a result of higher values in the warm season, i.e. sea levels tend to be higher during the hurricane season. We use information on the steric sea level component, sea surface and air temperature, wind forcing, precipitation, and sea level pressure to explain the mechanisms driving the decadal variability in the annual amplitude and the rapid increase over the last decade in the eastern GOM. We have developed several multiple regression models (MRM) with a varying number of independent predictors to reconstruct the temporal changes back to the mid and early 20th century (depending on data availability of the predictors). The models are able to explain up to 85% of the observed variability (70% on average across sites) and major parts of the rapid increase in the early 21st century. Multicollinearity between the predictors makes it difficult to quantify the contribution of individual parameters to the increase but sensitivity tests outline that changes in the annual cycle of the air surface temperature (which in turn directly propagates into the sea surface temperature) played a dominant role. The MRMs allow us to reconstruct the seasonal sea level cycle back to the early 20th century at all tide gauge sites and will be used in a follow-up study in combination with regional climate model output to assess potential future changes.

Estudia la sustitución de modelos de atención al embarazo, parto y crianza, tradicionalmente opacos para varones y objeto de cuidados mediante agentes populares, por otros accesibles a la medicina académica. A partir de la situación existente a nivel popular en el último tercio del siglo XIX, exploramos la repercusión de campañas de divulgación científica - entendidas como crítica sin cuartel a lo que se construyó como cultura popular - y la proliferación de dispositivos asistenciales gratuitos. La oferta de vigilancia sobre la alimentación de lactantes permitió familiarizar a las madres con la asistencia facultativa en la enfermedad, hasta que, en la segunda mitad del siglo XX, la Pediatría se centró preferentemente en las patologías y la Puericultura dejó de ser especialidad médica para convertirse en identidad profesional subalterna.The article explores how childhood visits to doctors first became routine in Spain. The introduction of new models of prenatal care, childbirth, and childrearing required the extension of academic medicine into a terrain traditionally occupied by practitioners of popular medicine. Focusing on the status quo for most of the population in the final third of the nineteenth century, the study examines the repercussion of the era's scientific outreach campaigns (expressions of harsh criticism of what popular culture had constructed and the spread of free health assistance. In particular, it highlights how attention to the nutritional needs of nursing mothers helped these women gain familiarity with the medical assistance available in the case of illness - so much so that by the second half of the twentieth century, the issues of health education and promotion had been relegated to a secondary plane within the medical profession.

The Nestorians central area of living was thevicinity of Hakkari and on this geography, until XX. Century, they liveda semi-autonomous tribal life which was peculiar to them. Having livedtheir most brilliant era in the X. Century, the Nestorians hadencountered no serious problem with the Kurds, their neighbours, andwith the central authority until the second half of the XIX. Century. TheNestorians’ idea of having an independent state combined with thepolitical development caused by the missionary activities of the midXIX. Century and the domination struggle of states like Russia andBritain caused serious problems for Nestorians with the Kurds and theCentral Authority. The Nestorians settled in the British-controlledregion of Iraq after the military operation following the riots of 1915 and1924. The Ottoman Empire has always followed the fundamental policyof avoiding conflicts between ethnic groups as well as conflicts betweenethnic groups and itself. Because of the multiple conflicts going onbetween different ethnic groups over the empire and ongoing battles inso many different fronts, the Ottoman Empire could not achieve toimplement this policy.The studies on the Nestorians reveal that there is lack ofawareness about the current locations of the geography inhabited bythe Nestorians. It is evaluated that a such awareness is very importantto establish a historical bond between the past and the present and fora better understanding of the causes of the today’s problems from ahistorical perspective.

In a more abstract way, it introduces the idea of prevention and a first idea of self care that allows the individual to project himself into the future, in order to preserve his health.

    2013-10-01

    Full Text Available ResumenLejos de ser un concepto de índole técnica —el simple equilibrio higrotérmico entre las condiciones del clima y las constantes fisiológicas humanas— el confort es una idea culturalmente construida, que concierne a factores heteróclitos, como la relación de la arquitectura con el cuerpo, o el modo en que se conciben a través de este la naturaleza, el espacio y la materialidad. Sin embargo, la noción de confort no ha merecido toda la atención historiográfica que merece, de ahí la necesidad de una nueva perspectiva de índole estética y multidisciplinar. Tal punto de vista se ensaya en el artículo a través de una parcial y brevísima historia del confort que recoge los diferentes sentidos asignados al concepto a lo largo de los dos últimos siglos de acuerdo a una suerte de ‘poéticas’: la añeja poética del fuego, vinculada al confort regenerativo; las poéticas de la higiene y del hábitat, desarrolladas durante la modernidad como dogmas cientificistas y a la vez como coartadas estéticas, y, finalmente, la poética de las atmósferas, que da cuenta de las inquietudes contemporáneas sobre la percepción, la memoria y la sociabilidad. De tal repaso histórico puede concluirse que el bienestar no es un concepto objetivable ni aislable en la probeta del técnico o el científico, sino una noción compleja, formada por capas diversas que se entremezclan: fisiológicas, constructivas, estéticas, existenciales, sociales. La historia del confort es, de este modo, una suerte de versión reducida de la historia de la cultura.Palabras claveconfort, arquitectura, higiene, hábitat, atmósferaAbstractArchitectural history of the last two centuries shows that welfare, far from being a purely technical issue – a balance between weather and the physiological human constants – is a culturally constructed idea concerning diverse factors, such as the relationship between space and human body or the ways of conceiving nature in architecture. However, the notion of comfort has not received the historiographical attention it deserves, hence the need for a new perspective, aesthetic and multidisciplinary in nature. Such a view is discussed in this article through a brief and partial history of comfort that addresses the different meanings assigned to the concept over the past two centuries, in accordance with a kind of 'poetics': the longstanding poetics of fire, linked the regenerative comfort; the poetics of hygiene and habitat, developed during modernity as a scientifistic dogma and as an aesthetic alibi, and, finally, the poetics of atmospheres, which accounts for contemporary concerns about perception, memory and sociability. From this historical review we can conclude that welfare is not an objectifiable concept, nor an idea synthesized in the technician or scientist test tubes, but a complex notion consisting of several intertwined layers: physiological, constructive, aesthetic, existential, social. The history of comfort is, thus, a sort of small version of the history of culture.Key wordscomfort, architecture, hygiene, habitat, atmosphere
