Global modeling of pollutant transport and deposition from anthropogenic emission hot spots on global scale

Urban centers significantly contribute to anthropogenic air pollution, although they cover only a minor fraction of the Earth's land surface. Since the worldwide degree of urbanization is steadily increasing, the anthropogenic contribution to air pollution from urban centers is expected to become more substantial in future air quality assessments. The main objective of this thesis was to obtain a more profound insight in the dispersion and the deposition of aerosol particles from 46 individual major population centers (MPCs) as well as the regional and global influence on the atmospheric distribution of several aerosol types. For the first time, this was assessed in one model framework, for which the global model EMAC was applied with different representations of aerosol particles. First, in an approach with passive tracers and a setup in which the results depend only on the source location and the size and the solubility of the tracers, several metrics and a regional climate classification were used to quantify the major outflow pathways, both vertically and horizontally, and to compare the balance between pollution export away from and pollution build-up around the source points. Then in a more comprehensive approach, the anthropogenic emissions of key trace species were changed at the MPC locations to determine the cumulative impact of the MPC emissions on the atmospheric aerosol burdens of black carbon, particulate organic matter, sulfate, and nitrate. Ten different mono-modal passive aerosol tracers were continuously released at the same constant rate at each emission point. The results clearly showed that on average about five times more mass is advected quasi-horizontally at low levels than exported into the upper troposphere. The strength of the low-level export is mainly determined by the location of the source, while the vertical transport is mainly governed by the lifting potential and the solubility of the tracers. Similar to insoluble gas phase tracers, the low-level export of aerosol tracers is strongest at middle and high latitudes, while the regions of strongest vertical export differ between aerosol (temperate winter dry) and gas phase (tropics) tracers. The emitted mass fraction that is kept around MPCs is largest in regions where aerosol tracers have short lifetimes; this mass is also critical for assessing the impact on humans. However, the number of people who live in a strongly polluted region around urban centers depends more on the population density than on the size of the area which is affected by strong air pollution. Another major result was that fine aerosol particles (diameters smaller than 2.5 micrometer) from MPCs undergo substantial long-range transport, with about half of the emitted mass being deposited beyond 1000 km away from the source. In contrast to this diluted remote deposition, there are areas around the MPCs which experience high deposition rates, especially in regions which are frequently affected by heavy precipitation or are situated in poorly ventilated locations. Moreover, most MPC aerosol emissions are removed over land surfaces. In particular, forests experience more deposition from MPC pollutants than other land ecosystems. In addition, it was found that the generic treatment of aerosols has no substantial influence on the major conclusions drawn in this thesis. Moreover, in the more comprehensive approach, it was found that emissions of black carbon, particulate organic matter, sulfur dioxide, and nitrogen oxides from MPCs influence the atmospheric burden of various aerosol types very differently, with impacts generally being larger for secondary species, sulfate and nitrate, than for primary species, black carbon and particulate organic matter. While the changes in the burdens of sulfate, black carbon, and particulate organic matter show an almost linear response for changes in the emission strength, the formation of nitrate was found to be contingent upon many more factors, e.g., the abundance of sulfuric acid, than only upon the strength of the nitrogen oxide emissions. The generic tracer experiments were further extended to conduct the first risk assessment to obtain the cumulative risk of contamination from multiple nuclear reactor accidents on the global scale. For this, many factors had to be taken into account: the probability of major accidents, the cumulative deposition field of the radionuclide cesium-137, and a threshold value that defines contamination. By collecting the necessary data and after accounting for uncertainties, it was found that the risk is highest in western Europe, the eastern US, and in Japan, where on average contamination by major accidents is expected about every 50 years.

Kindesmisshandlung: Behandlung von psychischen Störungen im Zusammenhang mit Gewalt an Kindern

Auszug Im November 2006 stellten die Vereinten Nationen (UN) den jüngsten von einem unabhängigen Experten erstellten internationalen Bericht zu Gewalt an Kindern vor, wonach im Jahre 2002 weltweit schätzungsweise 53.000 Kinder durch Totschlag starben sowie 150 Mio. Mädchen und 73 Mio. Jungen unter 18 Jahren Opfer sexueller Misshandlungen wurden. In 31 von 200 Staaten sind körperliche Strafen von Auspeitschen bis Amputationen erlaubt und in knapp der Hälfte der Staaten ist die Körperstrafe an Schulen erlaubt (Pinheiro 2006). In Deutschland und Großbritannien sterben pro Woche zwei, in Frankreich drei, in Japan vier und in USA 27 Kinder an Misshandlung und Vernachlässigung. In einer vorangegangen Studie der UNICEF, dem Kinderhilfswerk der Vereinten Nationen, wurde festgestellt, dass in den reichen Ländern auf 100.000 Kinder jährlich zwischen 0, 1 und 3, 7 Kinder unter 15 Jahren als Folge von Misshandlung oder Vernachlässigung sterben (⊡ Abb. 48.1 ). Schätzungen gehen davon aus, dass auf einen Todesfall rund 150 Fälle von Kindesmisshandlung ohne Todesfolge kommen (UNICEF 2003).

Why Freeter and NEET are Misunderstood: Recognizing the New Precarious Conditions of Japanese Youth

In developed countries, the transition from school to work has radically changed over the past two decades. It has become prolonged, complicated and individualized (Bynner et al., 1997; Walther et al., 2004). Young people used to transition directly from school to stable employment, or with a very short unemployed period. In many European countries, this situation has been changing since the eighties: overall youth unemployment has increased, and many young people experience long periods of unemployment, government training schemes and part-time or temporary jobs. In Japan, this change has taken a decade later to appear, becoming prevalent by the late nineties (Inui, 2003). The transiting process has become not only precarious for young people, but also difficult for society to precisely understand the risks and problems. Traditionally, we have been able to recognize young people's situation by a simple category: in education, employed, in training or unemployed. However, these categories no longer accurately represent young people's state. In Japan, most young people used to move from school directly to full-time employment through the new graduate recruitment system (Inui, 1993). Therefore, in official statistics such as the School Basic Survey, 'employed' includes only those who are in regular employment, while those who are in part-time or temporary work are covered by the categories 'jobless' and 'others'. However, with the increase in non-full-time jobs in the nineties, these categories have become less useful for describing the actual employment conditions of young people. Indeed, this is why, in the late of nineties, the Japanese Ministry of Education changed the category name from 'jobless' to 'others'.

Eheschließung auf japanisch

Hochzeiten sind Feste, die in der Regel von lokalen Traditionen bestimmt werden. Anders in Japan: Japanische Paare orientieren sich bei ihrer Hochzeit sehr häufig nicht mehr an der eigenen kulturellen Überlieferung, sondern kopieren westlich-christliche Hochzeitsfeiern mit langen weißen Brautkleidern und gotischen Kapellen. Rund um diese Hochzeitskultur existiert eine Infrastruktur aus kopierten Bauten, Kulissen und Atmosphären.

Political process and government growth: a theoretical and empirical investigation

A striking feature of virtually al western industrialized countries sice the middle of the past century has been the persistent growth of their government sector. From the beginning of the century to the late 1970's, the government expenditures' share of gross national product has increased from 7% to 36% in the U.S., 11% to 40% in the U.K., and 3% to 25% in Japan. In Germany, it went from 7% to 42% (1872-1978), while in France it soared from 11% to 59% (1872-1979). The evolution of the number of government employees followed a similar pattern. In the U.S., for instance, the average annual rate of growth of the government labor force over the period 1899-1974 has been 3.17%, compared to a 1.62% average annual growth rate of the working population. Less quantifiable aspects like the number and scope of regulations also refelct a growing public sector.

Pion emission from the T2K replica target: method, results and application

The T2K long-baseline neutrino oscillation experiment in Japan needs precise predictions of the initial neutrino flux. The highest precision can be reached based on detailed measurements of hadron emission from the same target as used by T2K exposed to a proton beam of the same kinetic energy of 30 GeV. The corresponding data were recorded in 2007-2010 by the NA61/SHINE experiment at the CERN SPS using a replica of the T2K graphite target. In this paper details of the experiment, data taking, data analysis method and results from the 2007 pilot run are presented. Furthermore, the application of the NA61/SHINE measurements to the predictions of the T2K initial neutrino flux is described and discussed.

International Frameworks for Disaster Risk Reduction: Useful Guidance for Sustainable Mountain Development?

In recent decades, a number of global frameworks have been developed for disaster risk reduction (DRR). The Hyogo Framework for Action 2005–2015 and its successor document, the Sendai Framework for Disaster Risk Reduction, adopted in Japan in March 2015, provide general guidance for reducing risks from natural hazards. This is particularly important for mountainous areas, but DRR for mountain areas and sustainable mountain development received little attention in the recent policy debate. The question remains whether the Hyogo and Sendai frameworks can provide guidance for sustainable mountain development. This article evaluates the 2 frameworks in light of the special challenges of DRR in mountain areas and argues that, while the frameworks offer valuable guidance, they need to be further adapted for local contexts—particularly for mountain areas, which require special attention because of changing risk patterns like the effects of climate change and high land-use pressure.

MS 073 Guide to the William C. Moloney MD papers; 1952-1954

William C. Moloney MD kept a personal journal, with photographs, for much of his two years in Japan with the Atomic Bomb Casualty Commission. In January of 1986, Dr.Moloney donated his journal, correspondence and diary pages to the Harris County Medical Archive. He died in 1998 at the age of 91. His first contribution was a set of ten reprints representing his work with the ABCC from 1952 to 1954. Dr.Moloney's journal is a fine document, one which will be of great use to historians. It is an important record of personal impressions, thoughts and details of events. The journal gives new insights into the work of the ABCC and into the people who participated in that work. Dr. Moloney wrote in his journal from April 1952 to February 1954. The Korean War was on and there was a great deal of military activity in southern Japan. The collection is open for research. The collection consists of a handwritten journal, loose calendar or notebook pages and some reprints. The journal is in generally fair condition. The paper is slightly acidic and the binding is loose. There are numerous photos glued onto the pages. The collection encompasses the years 1952-1954 and is 0.25 cubic feet (1 box).

MS#73 William C. Moloney, M.D., papers; 1952-1954

Dr. Moloney kept a personal journal, with photographs, for much of his two years with the Atomic Bomb Casualty Commission in Japan. Along with other scientists, he studied the biological and medical effects of ionized radiation on the survivors of the Hiroshima and Nagasaki atomic bombings. In January of 1986, Dr. Moloney donated his journal, correspondence and diary pages to the Harris County Medical Archive, whose collections were later incorporated into the Texas Medical Center Library. Dr. Moloney's journal is in relatively good shape containing a mix of handwritten notes and comments, news-clippings, photos, and ephemera. The journal is an important record of personal impressions, thoughts and details of events during a pivotal time in Japan. This 192-pagee journal gives new insights into the work of the ABCC and into the people who participated in that work. The journal covers the period from April 1952 to February 1954. In these documents, Moloney records his struggles with understanding the Japanese culture, his frustration at not being allowed to treat the survivors he studied, and his concerns, fears, hopes and revelations as he dealt with the bombing survivors and their children. The original papers are open for research at the John P. McGovern Historical Collections and Research Center in the TMC Library in Houston.

Sediment geochemistry of ODP Leg 127 sites

The relative effects of paleoceanographic and paleogeographic variations, sediment lithology, and diagenetic processes on the final preserved chemistry of Japan Sea sediments are evaluated by investigating the rare earth element (REE), major element, and trace element concentrations in 59 squeeze-cake whole-round and 27 physical-property sample residues from Sites 794, 795, and 797, cored during ODP Leg 127. The most important variation in sedimentary chemical composition is the increase in SiO2 concentration through the Pliocene diatomaceous sequences, which dilutes most other major and trace element components by various degrees. This biogenic input is largest at Site 794 (Yamato Basin), moderately developed at Site 797 (Yamato Basin), and of only minor importance at Site 795 (Japan Basin), potentially reflecting basinal contrasts in productivity with the Yamato Basin recording greater biogenic input than the Japan Basin and with the easternmost sequence of Site 794 lying beneath the most productive waters. There are few systematic changes in solid-phase chemistry resulting from the opal-A/opal-CT or opal-CT/quartz silica phase transformations. Most major and trace element concentrations are controlled by the aluminosilicate fraction of the sediment, although the effects of diagenetic silica phases and manganese carbonates are of localized importance. REE total abundances (Sum REE) in the Japan Sea are strongly dependent upon the paleoceanographic position of a given site with respect to terrigenous and biogenic sources. REE concentrations at Site 794 overall correspond well to aluminosilicate chemical indices and are strongly diluted by SiO2 within the upper Miocene-Pliocene diatomaceous sequence. Eu/Eu* values at Site 794 reach a maximum through the diatomaceous interval as well, most likely suggesting an association of Eu/Eu* with the siliceous component, or reflecting slight incorporation of a detrital feldspar phase. SumREE at Site 795 also is affiliated strongly with aluminosilicate phases and yet is diluted only slightly by siliceous input. At Site 797, SumREE is not as clearly associated with the aluminosilicate fraction, is correlated moderately to siliceous input, and may be sporadically influenced by detrital heavy minerals originating from the nearby rifted continental fragment composing the Yamato Rise. Ce/Ce* profiles at all three sites increase essentially monotonically with depth and record progressive diagenetic LREE fractionation. The observed Ce/Ce* increases are not responding to changes in the paleoceanographic oxygenation state of the overlying water, as there is no independent evidence to suggest the proper oceanographic conditions. Ce/Ce* correlates slightly better with depth than with age at the two Yamato Basin sites. The downhole increase in Ce/Ce* at Sites 794 and 797 is a passive response to the diagenetic transfer of LREE (except Ce) from sediment to interstitial water. At Site 795, the overall lack of correlation between Ce/Ce* and Lan/Ybn suggests that other processes mask the diagenetic behavior of all LREEs. First-order calculations of the Ce budget in Japan Sea waters and sediment indicate that ~20% of the excess Ce adsorbed by settling particles is recycled within the water column and that an additional ~38% is recycled at or near the seafloor. Thus, because the remaining excess Ce is only ~10% of the total Ce, there is not a large source of Ce to the deeply buried sediment, further suggesting that the downhole increase in Ce/Ce* is a passive response to diagenetic behavior of the other LREEs. The REE chemistry of Japan Sea sediment therefore predicts successive downhole addition of LREEs to deeply buried interstitial waters.
