ABSTRACTThis article analyzes differences between United States and West German export controls. It shows that United States controls are more extensive and stricter than controls in West Germany. Three possible explanations for this variation in policy are considered. First, these two states differ in regard to their positions in the international system and in their choice of economic strategies. Second, the extent of domestic political support for strict export control policies varies between the two countries. Finally, West Germany lacks the institutional framework to adequately control its foreign trade. The evidence presented corroborates the first two alternatives, while institutional explanations receive relatively little support. The article then discusses the historical development of United States and West German export control policies and institutions. The analysis shows evidence of both change and stability. More specifically, the article questions the argument that institutions in foreign economic policy, once established, persist and resist change, instead of adapting to environmental changes. Several hypotheses are considered to explain why in the area of export controls changes in policy, and to some extent institutions, occurred more frequently in West Germany than in the United States.

More than in many other countries, the oil market in West Germany is traditionally characterised by liberal trade patterns. This open market allowed a virtually free inflow of oil products. Hence, the pressure on prices at Rotterdam's spot market affected directly the product prices for German consumers. In all end-product markets, oligopoly and strong competition by outsiders prevail. If the cutthroat competition is intensified, this may lead to an alteration of the supply structure within the group of the quite heterogeneous market participants. The West German oil industry is passing through a period of painful economic adjustments. The shrinking of the market, changing demand patterns, and financial losses have led to the shedding of considerable over-capacity in refining and distribution. The process includes both a drastic reduction of simple (straight-run) distillation capacity and an increase in conversion potential, along with toll refining, reduction of marketing outlets, concentration of participants in processing and distribution, attempts at optimisation of downstream activities within the Common Market area, as well as the promotion of joint ventures with foreign state companies. The approach to the adaptation process varies from company to company according to upstream and downstream strength, financial position, access to sources of supply, international linkages, and special areas of interest. Of course, over-capacity of refining is a global phenomenon that cannot be eliminated without international co-operation. The problems may, after all, become even more complex after new export refineries in OPEC countries have been completed. This paper presents the results and features that reflect the reaction of the main companies affected. It describes the chances and challenges of a free oil market system. In recent years the petroleum industry in Germany has suffered heavy financial losses, and has embarked on a radical and seemingly successful adaptation process, but it remains vulnerable to developments on the world oil market. It would gain from better co-ordinated policies within the framework of the European Community—including a free play of market forces and a standardisation of environmental controls. Farther afield, the necessity for closer links to the government-controlled companies in producing countries is perceived to secure sources of supply on a basis of mutual advantage.

The article examines the specificity of commodities exports of Germany’s eastern and western lands. The indicators of sectoral export specialization are determined by comparing sectoral export quotas of the federal lands and the East/West with the general German sectoral export quotas. Calculations are based on data from the country's Federal Statistical Office for 2008 and 2019. As a result of the analysis of the indicators obtained, the general characteristics of the export specifics in relation to industrial branches and federal lands in two parts of the country are formulated, changes among the main specialized branches are explored, the roles of individual lands in the creation of export profiles of East and West Germany and the degree of correspondence between export profiles of the East/West and their lands are determined. The author outlines the convergence of new and old lands in various dimensions of specialization, the success of the East in the competition for specialization in the cars export and the preservation of significant Western advantages in the mechanical engineering’s export specialization and in the formation of new sectoral export focuses, and highlights the federal lands that have achieved high efficiency in the given field (Saxony in the East and Baden-Württemberg in the West).

Full textAbstract:
Increased government scrutiny of cross-border university research relationships, tightened export controls on technologies, and strengthened national regimes regulating technology-related foreign direct investment are now priorities for most democracies. These policy changes are motivated by the common goal of shoring up economic and national security. But the approaches are neither uniform nor harmonized, even among the relatively homogeneous G7 nations, undermining cross-border research and development (R&D) collaboration. When the leaders of G7 meet in late June in Schloss Elmau, Germany, they should make it a priority to coordinate controls on knowledge flows and technology. They need to act together to demonstrate how democracies can counter illicit activities for acquiring technologies.

The war of Germany against the USSR was based on the idea of expanding the "living space" of the German nation, capable of using the resources of the occupied territories of the Soviet republics for the benefit of its own development. The population of the countries destined for conquest must feed the German economy with man power resources, the natural reserves of their former territories will provide the economic needs of the German army and the entire German people. The most important tool for the economic use of the occupied territories was the tax system, the export of production equipment, property of organizations and citizens. For staffing industrial production in the occupied territories, labor exchanges were created, distributing the civilian population to work at local enterprises. The occupation caused enormous damage to the population, economy and economy of the North-West of Russia. The number of the local population, which was destroyed in concentration camps, was subjected to robberies and terror, and was mobilized for defensive and other work, significantly decreased. The population experienced constant hunger, only those who were involved in compulsory work in production received the minimum supply. A significant number of able-bodied citizens of the occupied regions of the North-West were sent to forced labor in Germany. The violent deportation of the population to Germany was accompanied by unprecedented cruelty and brutal reprisals. In the face of intensified repression, the process of mass entry of the rural population into partisan detachments began.

Yearly 4 900 000 tons of hazardous waste are generated in West Germany. The Germany Waste Disposal Act regulates not only the import and the export, but also the transit of wastes. Also avoidance of waste generation and recycling of wastes are emphasized by the act. To reduce waste amounts the collected wastes are treated preliminarily by chemical, physical and biological methods. 740 000 tons of hazardous waste are combusted annually in 27 incineration plants. 18 additional incineration plants are planned. Disposal of diluted acids in the North Sea was completely stopped by the end of 1989. Chlorinated hydrocarbons were burned on a German incineration ship. This was stopped in 1989. The most usual disposal process is the sanitary landfill. Rainfall results in water and soil pollution caused by leachates. A roof above the landfill could eliminate the generation of leachates. The safest disposal is the deep underground deposition in salt domes.

Full textAbstract:
The German economy is recovering hesitantly from the sharp post-unification boom and recession. Two features of recent West German performance are novel: there has been an unprecedented loss of jobs in industry, and manufacturing profitability has been pushed to its lowest level ever and is now low relative to other OECD economies. Serious problems with labour costs and innovation would be expected to show up in a weakening in the trend of export performance. That this has not yet happened is the consequence of the existence of an apparently robust innovation system which enables companies to pursue high quality incremental innovation strategies. However, the experiment of transferring the West German model to the East has proved extremely costly and has not so far established the basis for self-sustaining growth. Problems in profitability, investment and employment in West Germany reflect the failure of the bargaining system—unions, employers, Bundesbank and public sector—to negotiate the sharing of the burden of unification.

After India's detonation of a nuclear explosive in 1974 publicly demonstrated the proliferation risks from nuclear assistance, the U.S. government increased its efforts to control nuclear exports worldwide. In doing so, U.S. policymakers faced challenges from two major West European allies, France and West Germany, both of which pursued their commercial interests through nuclear exports to countries such as Pakistan, Brazil, Iran, and India, among others. Despite multilateral efforts including the formation of the Nuclear Suppliers Group and bilateral negotiations with the supplier governments, the administrations of Gerald Ford and Jimmy Carter attained only partial success. The commercial interests of nuclear firms, the influence of pro-export coalitions inside supplier countries, and the emerging importance of the Soviet Union and other Warsaw Pact countries as alternative suppliers influenced the outcome. The United States was more successful in restraining the French through a series of quid pro quo arrangements than it ever was with the West Germans. Using recently declassified archival documents, this article sheds new light on U.S. nonproliferation policy in the aftermath of the 1973 oil price shock.

Over the past decade Germany has had one of the most successfuleconomies in the developed world. Despite the ongoing Euro crisis unemploymenthas fallen below 7 percent, reaching its lowest levels since Germanreunification in 1990. Germany’s youth unemployment is among thelowest in Europe, far beneath the European average.1 One of the mostimportant engines of the German economy today, and in fact throughoutthe twentieth and twenty-first centuries, has been its export sector. As LudwigErhard, West Germany’s Economics Minister during the Wirtschaftswunderof the 1950s remarked: “foreign trade is quite simply the core andpremise of our economic and social order.”2 According to various estimates,today exports and imports of goods and services account for nearly a half ofGerman GDP—up from only a quarter in 1990. Germany is one of only threeeconomies that do over a trillion dollars worth of exports a year, the othertwo being the United States and China.

Despite record levels of domestic production, forecasters are predicting that the east coast Australian gas market will remain tight in 2019. The introduction of the Australian Domestic Gas Security Mechanism (ADGSM) by the Federal Government in 2017, and the proposal announced by the Australian Labour Party (ALP) to bolster the mechanism, have again thrust the issue of political intervention in the export gas market into sharp focus. This paper provides an overview of the current regulatory intervention at the state and federal level, and looks back at the history of controls imposed upon the Australian gas export market. The paper is divided into two parts: Part 1, which looks at current regulatory controls engaged by various State and Federal governments: (a) the development and implementation of the ADGSM; (b) the development and implementation of the Queensland Government’s Prospective Gas Production Land Reserve policy (PGPLR); and (c) the Government of Western Australia’s (WA Government) domestic gas policy. The paper also reviews policy announcements made by the ALP in the lead up to the 2019 Federal election. Part 2 provides a broad overview of the history of controls on gas exports in Australia, from the embargo on exports from the North West Shelf between 1973 and 1977, through the increasing liberalisation of Australian energy policy during the 1980s and 1990s (and the associated conflict with state concerns of ensuring sufficiency of the domestic supply of gas), up to the removal of federal controls on resources exports (including liquefied natural gas) in 1997.

Abstract. The 2 June 2008 flood-producing storm on the Starzel river basin in South-West Germany is examined as a prototype for organized convective systems that dominate the upper tail of the precipitation frequency distribution and are likely responsible for the flash flood peaks in Central Europe. The availability of high-resolution rainfall estimates from radar observations and a rain gauge network, together with indirect peak discharge estimates from a detailed post-event survey, provided the opportunity to study in detail the hydrometeorological and hydrological mechanisms associated with this extreme storm and the ensuing flood. Radar-derived rainfall, streamgauge data and indirect estimates of peak discharges are used along with a distributed hydrologic model to reconstruct hydrographs at multiple locations. Observations and model results are combined to examine two main questions, (i) assessment of the distribution of the runoff ratio for the 2008 flash flood and how it compares with other less severe floods; and (ii) analysis of how the spatial and temporal distribution of the extreme rainfall, and more specifically storm motion, controls the flood response. It is shown that small runoff ratios (less than 20%) characterized the runoff response and that these values are in the range of other, less extreme, flood events. The influence of storm structure, evolution and motion on the modeled flood hydrograph is examined by using the "spatial moments of catchment rainfall". It is shown that downbasin storm motion (in the range of 0.7–0.9 m s−1) had a noticeable impact on flood response by increasing the modeled flood peak by 13%.

Full textAbstract:
Saratoga Scleropages jardinii (Saville-Kent 1892) is a popular aquarium and sportsfish native to southern New Guinea and northern Australia. In recent years the people of the Bensbach River area in Papua New Guinea's Western Province have been harvesting wild fingerlings for sale across the nearby international border in Indonesia's Papua Province. From there the fish are sold to dealers in other parts of Asia. The species is protected by law in Indonesia, and subject to various regulations in Australia. In Papua New Guinea there are no controls on its exploitation. Uncontrolled harvesting of fingerlings from the Bensbach and other river systems in south New Guinea has had negative impacts on local fisheries, and led to a decline in the Australian export trade in wild-caught and farm-bred Saratoga.

AbstractUnnoticed Disappearance – The Decline of the West-German Clothing Industry in the 1960s/70sIn the beginning of the 20th century the German clothing industry used to be a considerable producer of consumer goods, manufacturing clothes for both home and export market. In the 1960s and 70s this branch of the German industry began to decline, mainly due to the pay gap between the labor costs in Germany and low-wage-countries located in Eastern Europe and Asia. In response to this development bigger German companies outsourced their production abroad to save labor costs. Smaller companies often lacked the needed financial resources and had to face bankruptcy as result. At the end only services like planning and quality control remained in Germany. In consequence of this development a lot of German seamstresses lost their jobs. The government did not care about these problems; the enterprises did not receive subsidies. The unions in the sector were weak due to a high percentage of working women and the high ratio of small and medium sized regionally dispersed enterprises.

Germany has been growing political and military activity in Northern Africa and Sahel region by the mid 2010s. FRG and its EU partners faced the great number of instability risks which are projected from zones of armed conflicts located in northern part of Africa. The key elements of the corridor of instability which has connected the fragile states in Sahel and Northern Africa were the «Libyan door» (the upper part) and «Malian gates» (the lower one). But in the 2010s FRG faced the absence of opportunities for itself to be directly involved in the resolution of «Libyan problem». That is why in 2012-2019 Germany had been trying only to fence «Libyan problem» in. This perimeter has four segments. German contribution to the creation of Western one (the strengthening of Tunisian and Algerian borders with Libya) and especially Eastern segment (the same with Egypt) was rather limited and consisted of arms export to these countries. The article explores the evolution of German participation to the resolution of Mali armed conflict (first of all FRG`s military contribution to EUTM Mali and MINUSMA missions). This one and also German participation in the reform of Niger`s security sector was the creation of Southern segment of the perimeter. By 2020 Germany has deepened cooperation on «Libyan problem» not only with regional players but also world powers. During Merkel`s visit to Moscow (January 11, 2020) the scheme of future Berlin conference on Libya was declared. This format was established on January 19, 2020. Germany became the coordinator of inter-Libyan dialogue (between the Government of national consensus in the West of the country and Libyan national army in the East) and supported it by the launch of the EU mission «IRINI». The article concludes about the perspectives of German policy towards Libya considering COVID-19 pandemics.

The 1950s in Germany, especially the period 1953–1958, were later recognised as the ‘golden years of the post-war period’. By the end of this period, most of the war damage had been removed and the economy was in a state of dynamic growth. In the period 1949–59, the average real GDP growth rate was about 7.4% with an average investment rate of 24.2% (in current prices). In the years (1950–53), a massive housing construction programme was carried out that was financed almost in half from public funds. Germany’s economic growth in 1950–60 mainly influenced by investment activities and the growth of exports. During this period, state expenditure did not play a major role in the growth of the West German economy (its share in national income steadily declined during the period in question). A the same time, the share of exports in national income was very high and showed a continuously increasing trend. A long-term growth of exports — affecting constantly the expansion of demand — became an important factor stimulating investment activity, which is the main lever of economic growth. At the same time, unusually strong export activity improved the balance of payments, which showed systematic surpluses. It should also be stressed that private consumption was not a factor driving economic prosperity in West Germany in this period. The share of consumption in Germany’s national income showed a declining trend in favour of investment.

Historical Survey of the Railway Development in West Africa The present day railway system in West Africa is the result of the transport-policy developed by the colonial powers (France, Great Britain and Germany) at the end of the 19th century. It is remarkable that no network of railways, like in Southern Africa, was brought about. The colonial railways in West Africa were built by the State or by a joint-stock company within the borders of one colony to export the raw materials from the production centres to the harbours. Nevertheless railways were built for more than economical grounds only, in West Africa they had to accomplish a strategic and military role by “opening Africa for the European civilization”. Hargreaves calls railways the “heralds of new imperialism” and Baumgart speaks of the own dynamics of the railways, to push the European colonial powers further into Africa ... The construction of a railway needed a very high capital investment and the European capitalists wouldn’t like to take risks in areas that were not yet “pacified”. It is remarkable how many projects to build a Transcontinental railway right across the Sahara desert largely remained on paper. Precisely because such plans did not materialize, however, the motive force they provided to such imperialist actions as political-territorial annexations can be traced all the more clearly. The French built the first railway in West Africa, the Dakar - St-Louis line (Senegal), between 1879 and 1885. This line stimulated the production of ground-nuts, although the French colonial-military lobby has had other motives. The real motivation became very clear at the construction of the Kayes-Bamako railway. Great difficulties needed the military occupation of the region and the violent recruitment of thousands of black labourers, all over the region. The same problems transformed the building of the Kayes-Dakar line into a real hell. Afterwards the Siné Saloum region has been through a “agricultural revolution”, when the local ground-nuts-producers have been able to produce for foreign markets. The first British railways were built in Sierra Leone and the Gold Coast-colony (Ghana). Jn Nigeria railway construction stimulated the growth of Lagos as an harbour and administrative centre. Lugard had plans for the unification of Nigeria by railways. The old Hausa town of Kano flourished after the opening of the Northern Railway, for other towns a period of decline had begun. Harbour cities and interior railwayheads caused an influx of population from periphery regions, the phenomenon is called “port concentration”. Also the imperial Germany built a few railwaylines in their former colony Togo, to avoid the traffic flow off to the British railways. ifs quite remarkable that the harbours at the Gulf of Guinea-coast developed much later than the harbours of Senegal and Sierra Leone. After the First World War only a few new railways were constructed, the revenues remained very low, so the (colonial) state had to take over many lines. The competition between railways and roadtransport demonstrated the first time in Nigeria, it was the beginning of the decline of railways as the most important transportsystems in West Africa. Only multinational companies built specific railways for the export of minerals (iron, ore and bauxite) after the Second World War, and the French completed the Abidjan - Ouagadougou railway (1956). The consequences of railway construction in West Africa on economic, demographic and social sphere were not so far-reaching as in Southern Africa, but the labour migration and the first labour unions of railwaymen who organized strikes in Senegal and the Ivory Coast mentioned the changing social situation. The bibliography of the West African railways contains very useful studies about the financial policy of the railway companies and the governments, but only a few railways were already studied by economic historians.

Since German unification, assessments of the German economy have swung from “sick man of the euro” in the early years to dominant hegemon of late. I argue that the German economy appears strong because of its recent positive performance in two politically salient areas: unemployment and the current account. A deeper assessment reveals, however, that German economic performance cannot be considered a second economic miracle, but is at best a mini miracle. The reduction in unemployment is an important achievement. That said, it was not the product of faster growth, but of sharing the same volume of work among more individuals. Germany’s current account surpluses are as much the result of weak domestic demand as of export prowess. Germany has also logged middling performances in recent years regarding growth, investment, productivity, and compensation. The article also reviews seven challenges Germany has faced since unification: financial transfers from west to east, the global financial crisis, the euro crisis, internal and external migration, demographics, climate change, and upheavals in the automobile industry. German policy-makers managed the first four challenges largely successfully. The latter three will be more difficult to tackle in the future.

Full textAbstract:
Australia's North West Shelf Project is based on the development of major gas reserves discovered in the early 1970s in deep water some 130 km off the coast from Dampier, Western Australia.The project was developed in two phases. The Domestic Gas Phase, completed in 1984, supplies pipeline gas to the State Energy Commission of Western Australia for distribution in the south-west of the State. The Liquefied Natural Gas (LNG) Phase involves the export of LNG to eight Japanese power and gas utilities under 20-year Sale and Purchase Agreements. The production and export of LNG commenced in 1989.A Total Hazard Control Plan (THCP) has been developed for the project's onshore and offshore facilities to ensure that all hazards which could affect public safety outside the plant boundary are identified and controlled for the life of the site.The THCP applies to all sites, including the trunkline, onshore gas treatment plant, King Bay supply base and North Rankin A offshore platform. The objectives of the THCP are: to identify the hazards that exist together with their potential consequences; to list the policies and procedures which control the hazards and assign responsibility within the organisation to ensure that those policies and procedures are implemented; to provide verifiable assurance to Government that the Project Operator, Woodside, comprehensively and systematically controls all foreseen hazards to public safety, at the level of 'reasonably practicable'.Compliance with the THCP is verified using a structured auditing programme involving both internal and external audits.

Abstract. Understanding the controls on event-driven dissolved organic carbon (DOC) export is crucial as DOC is an important link between the terrestrial and the aquatic carbon cycles. We hypothesized that topography is a key driver of DOC export in headwater catchments because it influences hydrological connectivity, which can inhibit or facilitate DOC mobilization. To test this hypothesis, we studied the mechanisms controlling DOC mobilization and export in the Große Ohe catchment, a forested headwater in a mid-elevation mountainous region in southeastern Germany. Discharge and stream DOC concentrations were measured at an interval of 15 min using in situ UV-Vis (ultraviolet–visible) spectrometry from June 2018 until October 2020 at two topographically contrasting subcatchments of the same stream. At the upper location (888 m above sea level, a.s.l.), the stream drains steep hillslopes, whereas, at the lower location (771 m a.s.l.), it drains a larger area, including a flat and wide riparian zone. We focus on four events with contrasting antecedent wetness conditions and event size. During the events, in-stream DOC concentrations increased up to 19 mg L−1 in comparison to 2–3 mg L−1 during baseflow. The concentration–discharge relationships exhibited pronounced but almost exclusively counterclockwise hysteresis loops which were generally wider in the lower catchment than in the upper catchment due to a delayed DOC mobilization in the flat riparian zone. The riparian zone released considerable amounts of DOC, which led to a DOC load up to 7.4 kg h−1. The DOC load increased with the total catchment wetness. We found a disproportionally high contribution to the total DOC export of the upper catchment during events following a long dry period. We attribute this to the low hydrological connectivity in the lower catchment during drought, which inhibited DOC mobilization, especially at the beginning of the events. Our data show that not only event size but also antecedent wetness conditions strongly influence the hydrological connectivity during events, leading to a varying contribution to DOC export of subcatchments, depending on topography. As the frequency of prolonged drought periods is predicted to increase, the relative contribution of different subcatchments to DOC export may change in the future when hydrological connectivity will be reduced more often.

Full textAbstract:
In this piece I look at the BRICS bloc (Brazil, Russia, India, China, and South Africa) as rivals of the West, united more by circumstance than by intent. It emerged as a seemingly innocuous banker’s gimmick referring to the ‘emerging market’ potential of the countries thus thrown together, but due to the aggressive Western response to independent policies, the BRICS have slowly moved towards solidifying their cohesion. Comprising half the world’s population, the bloc on the eve of the financial crisis of 2008 was closing in on the West. In Purchasing Power Parity (PPP) terms, China’s GDP was three-quarters the size of the US economy, and India no. 4 behind Japan, whilst Brazil and Russia were catching up with the main EU states (Armijo 2007: 12). The 2008 financial collapse in the West contracted China’s export markets and speculation that the BRICS were passé, was rife (Sharma, 2012: 6). However, China and India soon recovered, surpassing the US and Japan, respectively, whilst Russia and Brazil are trailing just behind Germany (World Bank 2016).This (uneven) recovery of the BRICS bloc in turn has provoked an even less benevolent response, increasingly amounting to a straightforward confrontation policy. My argument is that once the crisis forcedChina, the bloc’s locomotive, to slow down and the global commodity boom ended, a Western strategy of isolating it from the other BRICS ensued. This is most obvious in the case of the NATO siege on Russia.

SUMMARYIn Baden-Wuerttemberg, a federal state in south-west Germany, a large outbreak of 1089 laboratory-confirmed human Puumala virus (PUUV) infections occurred in 2007. We conducted a survey to describe the disease burden and a case-control study to identify risk factors for acquiring PUUV. Case-patients were interviewed about clinical outcome and both case-patients and randomly recruited controls were interviewed about exposure. We calculated matched odds ratios (mOR) using a conditional logistic regression model. Multivariable analysis of 191 matched case-control pairs showed that case-patients were more likely than controls to have seen small rodents/their droppings (mOR 1·9, 95% CI 1·2–3·0), cleaned utility rooms (mOR 1·8, 95% CI 1·0–3·4) and visited forest shelters (mOR 3·9, 95% CI 1·1–14·3). Two thirds of case-patients required hospitalization. During PUUV epidemics rodent control measures and use of protective equipment should be considered in utility rooms and shelters.

Full textAbstract:
This article offers a Japanese perspective on the debate about the international financial system immediately after the first oil shock of 1973–4. Using archival records from the OECD and Bank of Japan, I analyze the three key policy issues discussed at the meetings of Working Party 3 (WP3) of the OECD: petrodollar recycling, balance-of-payments adjustments, and the management of global growth. Documents show that the Japanese approach to capital controls, exchange rate management, state-led growth orientation and international banking strategies was rather strengthened by the impact of the oil shock. By 1975 the OECD viewed Japan, together with Germany and the United States, as one of the ‘locomotives’ that would trigger a revival of economic growth in the industrialized West.

Full textAbstract:
Pakistan follows the flexible exchange rate system since July 2000. Prior to this period it followed a managed floating exchange rate since 1982 and a fixed rate prior to 1982. Due to controlled exchange rate a little fluctuation in exchange rate was observed. It is empirical concluded that the Pakistan’s share of exports in world market did not indicate any significant change during fixed and managed floating exchange rate regimes [Kumar and Dhawan (1991)]. Pakistan’s share in world exports was stable during the last 24 years, ranging between a minimum of 0.12 percent in 1980 and a maximum of 0.18 percent in 1992. After introduction of floating exchange rate during 2002-2003 (the share was 0.17 percent) Pakistan’s exports performance was related to the volatility of exchange rate. Only one empirical study is available regarding to Pakistan’s context by Kumar and Dhawan (1991) who estimated the impact of exchange rate volatility on Pakistan exports to the developed world from 1974 to 1985. They found that volatility of exchange rate adversely effect on export demand. They also investigated the third country effect and suggested that Japan and West Germany act as the alternate market for Pakistan’s export to the United States and United Kingdom. The high degree of volatility and uncertainty of exchange movements observed in Pakistan is of great concern of policy-makers and researchers to investigate the nature and extent of the impact of such movements on Pakistan’s volume of trade. In many countries it is experienced that higher exchange rate volatility reduced the trade by creating uncertainty about future profit from exports.

Full textAbstract:
Human salmonellosis in Germany has been an increasing problem since the 1980s, with a peak of 195000 reported cases in 1992. During the peak years, isolates of Salmonella Enteritidis (SE) predominated by far over other salmonella serovars (NSE) (80 vs. 20%). In a comparison of the clinical characteristics of 790 persons infected with SE to 175 persons infected with NSE, watery diarrhoea (OR 1·7) and high grade (> 39 °C) fever (OR 1·8) were independently associated with SE infection. When comparing possible risk factors for acquiring salmonella infection among patients with SE compared to those with NSE, consumption of raw eggs (OR 4·4; P = 0·0006) was the most significant alimentary risk factor for SE infection, while travel outside Europe was negatively associated with SE infection (OR 0·08; P = 0·0001). When comparing all patients with salmonella infection, regardless of serovar, with healthy controls, consumption of raw eggs (OR 30·3; P = 0·001), of raw or undercooked eggs (OR 1·9; P = 0·003), or having puppies, kittens or turtles (OR 6·8; P = 0·002), were risk factors for salmonellosis.

This study examines the impact of economic development and generational turnover on trends in sex differences in political participation. Election studies of the United States and West Germany are the sources of the trend data, which cover the period between 1952-1953 and 1980. Controls are imposed for increased education levels, the decreased preponderance of rural residents and farming families, and the replacement of older generations by younger ones. The results show that these socioeconomic processes have had a negligible impact on the sex difference trends. Furthermore, these socioeconomic processes cannot explain the variations in the rate of change by nation and by indicator of political participation. The article identifies different configurations of factors affecting the trends in voter turnout, in media attention and discussion, and in organizationally related types of campaign activity.

Many writers have argued that anti-immigration politics in Germanyand other West European countries have been driven by radical-rightparties or the electoral maneuvering of national politiciansfrom established parties. Others have argued that waves of violenceagainst immigrants and ethnic minorities have spurred anti-immigrationpolitics, or that racist ideologies and socioeconomic inequalityare the root causes. By comparison, authors have paid relatively littleattention to anti-immigration mobilization at subnational levels,including the public positions taken by subnational politicians andthe activities of movement groups, or “challengers.” Nonetheless,research has shown that subnational politicians are often importantin pressing national campaigns for immigration controls. Moreover,as I have argued elsewhere, anti-immigration politicians in Britainand Germany have responded in large part to local challengers, whowere aided by political elites at local and regional levels.

Full textAbstract:
In the framework of the EU-project RANR (Regional analysis of subsurface nitrogen retention and its impact on the nitrogen export from land to sea) a model system was developed to estimate groundwater-borne nitrogen inputs into river systems. The core of this model system is composed of a soil nitrogen leaching model (SOIL-N) and a groundwater residence time/denitrification model (WEKU). The application of the model system was carried out for the study catchment areas of the Uecker basin (ca. 2400 km2, Germany) and the Gjern basin (ca. 200 km2, Denmark). For both catchment areas, the modelled average nitrogen loads leached into the groundwater were about 40 kg N/ha a, while the remaining groundwater-borne nitrogen intake to rivers was quantified to an average of about 2 kg/ha a. The comparision with observed groundwaterborne riverine nitrogen loads showed a very good agreement, proofing the key role nitrogen retention in groundwater plays in the two catchment areas. With regard to the generalisationand transfer of the SOIL-N/WEKU model concept we assume that the model can be applicated in catchment areas in the European Pleistocene Lowland, which ranges from the Netherlands in the west to the Baltic States and the Ukraine in the east.

Full textAbstract:
The use of isolated regional perfusion in an adjuvant setting for stage I melanoma of the extremity continues to be controversial. The present retrospective study evaluates the past 20 years' experience by comparing 227 perfused patients from Groningen with 238 matched controls from five hospitals in The Netherlands and Westphalia (a region of West Germany bordering the Netherlands). All patients underwent wide local excision for a primary extremity melanoma of 1.5 mm or greater in thickness. A proportional hazards regression analysis for recurrence of disease and survival identified the significant prognostic factors, of which tumor thickness was the most important. Corrected for these factors, it was not possible to demonstrate a statistically significant effect for perfusion in terms of time to limb recurrence (P = .61), time to regional lymph node metastasis (P = .11), time to distant metastasis (P = .73), disease-free interval (P = .42), and survival (P = .90). No statistically significant differences were seen for adjuvant perfusion in any of the subgroups.

Full textAbstract:
Dynamic façades play an important role in enhancing the overall performance of buildings: they respond to the environmental conditions and adjust the amount of transmitted solar radiation. This paper proposes a simulation-based framework to evaluate the energy and comfort performance of different control strategies for switchable electrochromic glazing (EC). The presented method shows the impact of a model predictive control (MPC) on energy savings and on visual and thermal comfort for different orientations compared to other strategies. Besides manual operation and conventional rule-based controls, the benchmark in this study was a simulation-based control (multi-objective penalty-based control) with optimal performance. The hourly results of various control cases were analyzed based on the established performance indicators and criteria. The cumulative annual results show the capabilities and limitations of each control strategy for an EC glazing. For a temperate climate (Mannheim, Germany), results showed that an MPC for EC glazing provides visual and thermal comfort while saving energy of up to 14%, 37%, 37%, and 34% respectively for facing north, east, south, and west relative to the base-case.

In the article the author has analyzed the general principles of transport logistics in Ukraine. The main factors that determine the logistical activities and which have an influence on the choice of the mode of transport have been determined. The transportation of cargo by mode of transport was analysed, and outlined a place of road transport. In this paper conducted analytical studies to determine the sectoral structure of export of Ukraine’s regions to neighboring countries by automobile transport by means of transportation and information portal Ukraine “Lardi-trans”. According to the study from the regions highest exports to neighboring countries – produce timber and woodworking industry. Production of the industry ranks first in the structure of exports of goods Volyn, Rivne, Zhytomyr, Lviv, Ternopil, Khmelnytsky, Transcarpathian, Ivano-Frankivsk, Vinnytsia, Chernivtsi, Donetsk, Chernihiv and Sumy regions. Food products in the export structure dominated Kiev, Cherkassy, Poltava, Kharkiv, Odessa, Mykolayiv and Kherson regions. In other regions dominated by agricultural products – particularly Kirovohrad region, iron and steel products – Dnipropetrovsk region, Lugansk region – produce pulp and paper industry. In second place in the export structure in Western countries mainly agricultural products and foodstuffs. But in the eastern regions of the country is mostly engineering products. According to the study the regions of Ukraine were divided into 3 groups: West of the predominance in the structure of exports of forestry and wood processing industry, Central – dominated the food industry and agricultural and East – dominated, industries and mechanical engineering and metal working, chemical, steel and non-ferrous industry. In the work assessed exports by region of Ukraine with the release of several groups of regions and analyzed by mode of transport. An important role in the study covers evaluation of transit of goods by road through the territory of Ukraine with analysis of major trend and states – participants. Countries that use the transport system of Ukraine for the transit of their goods to third countries were divided into three groups. The first group includes Turkey, Russia and Moldova on transit volumes over 500 ths. tons. The second group consists of Romania, Italy, Belarus and Poland. The volume of transit through Ukraine up to 200 – 500 ths. tons. In the third group, with the least, but no less important for the economic development of Ukraine transit volumes include Bulgaria, Hungary, Greece, Slovenia and Germany. The basic tasks of transport logistics were defined in the article, including states which improve the quality of the transport infrastructure and transport services and bringing them up to global standards, the maximum load of the rolling stock, cargo insurance and vehicles.

Salah satu kebijakan Menteri Pertanian berkenaan dengan ekspor dan impor beras adalah peningkatan ekspor jenis beras khusus, seperti beras organik. Permintaan pasar global beras organik semakin meningkat, tetapi Indonesia menghadapi pesaing seperti Thailand dan Vietnam. Meskipun demikian, petani beras organik di Provinsi Jawa Barat menunjukkan kemampuan daya saingnya dengan keberhasilannya melakukan ekspor ke negara Amerika Serikat, Jerman, Malaysia, Singapura, Belanda, Italia, dan Dubai. Penelitian ini bertujuan menganalisis daya saing beras organik, dan mengidentifikasi dampak kebijakan pemerintah terhadap kegiatan usaha tani beras organik. Metode analisis yang digunakan adalah Policy Analysis Matrix (PAM). Hasil penelitian menunjukkan bahwa varietas beras organik memiliki daya saing yang cukup untuk ekspor, terlihat pada keunggulan kompetitif (Private Cost Ratio) dan komparatif (Domestic Resource Cost Ratio). Penerimaan secara finansial maupun sosial dapat memenuhi biaya input domestik. Keunggulan kompetitif dan komparatif melemah akibat dari adanya pengaruh biaya sertifikasi lahan pada biaya domestik dan biaya kemasan, sedangkan dampak kebijakan pemerintah terhadap input dan output menguntungkan petani. Kebijakan bersifat efektif namun belum efisien akibat belum adanya lembaga penyediaan input seperti pupuk dan benih organik. One of the agriculture minister policies related to rice exports and imports is the increased number of certain type of rice export such as organic rice.The global demand of organic rice market has been increasing but Indonesia is facing competitors, such as Thailand and Vietnam. Nevertheless, organic rice farmers in west java province are showing their competitive capability by exporting to a United States, Germany, Malaysia, Singapore, The netherlands, Italy, and Dubai. This study aims to analyze the competitiveness of organic rice, and identify the impacts in government policy for the organic rice farming.The result shows that some varieties of organic rice have adequate export competitiveness, seen from the competitive advantage (private cost ratio) and the comparative advantage (domestic cost ratio) which are positive. The analysis method used was Policy Analysis Matrix (PAM). The financial and social revenue could cover the input of domestic cost. The competitive and comparative advantages were weakened as a result of the influence of land certification in the domestic and packaging cost, whereas the impact of government policy to input and output is profitable for farmers. The policy is effective but has not been efficient due to lack of input providers such as fertilizer and organic seeds.

<b><i>Introduction:</i></b> Hypertension (HTN) and diabetes frequently coexist, imposing significant cardiovascular risk that is normally studied in terms of brachial blood pressure (bBP). Direct and superior parameters like central haemodynamics and arterial stiffness are studied scarcely. Pulse wave analysis (PWA) offers a non-invasive measurement of the same that we studied in diabetic hypertensives. <b><i>Materials and Methods:</i></b> We conducted a case-control study on 333 treated diabetic hypertensive cases and 333 euglycaemic normotensive controls. Oscillometric PWA was performed by Mobil-o-Graph (IEM, Aachen, Germany). Parameters were further analysed in relation to gender, physical activity, body mass index (BMI), glycaemic control, blood pressure control, and disease duration (cut-off 5 years). Multiple linear regressions were done to find significant associations. <b><i>Results:</i></b> Cases had significantly higher brachial haemodynamics (blood pressure, heart rate (HR), and rate pressure product); arterial stiffness measures (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, and pulse pressure amplification), and central haemodynamics (central blood pressure, cardiac output, stroke work) than controls. In the case group, female gender, BMI ≥23, and uncontrolled blood pressures were significant factors that affected the results while other factors such as glycaemic control, physical activity, and duration did not. HR was significantly associated with study parameters. Brachial pressures were not significantly associated with corresponding aortic pressures. <b><i>Conclusion:</i></b> Diabetic hypertensives had adverse profile of cardiovascular parameters beyond bBP, related to female gender, and HTN and its control, more than that of diabetes. This baseline work suggests further study on these potential parameters.

Abstract. The outflow of dust from the northern African continent towards the North Atlantic is stimulated by the atmospheric circulation over North Africa, which modulates the spatio-temporal distribution of dust source activation and consequently the entrainment of mineral dust into the boundary layer, as well as the transport of dust out of the source regions. The atmospheric circulation over the North African dust source regions, predominantly the Sahara and the Sahel, is characterized by three major circulation regimes: (1) the harmattan (trade winds), (2) the Saharan heat low (SHL), and (3) the West African monsoon circulation. The strength of the individual regimes controls the Saharan dust outflow by affecting the spatio-temporal distribution of dust emission, transport pathways, and deposition fluxes.This study aims at investigating the atmospheric circulation pattern over North Africa with regard to its role favouring dust emission and dust export towards the tropical North Atlantic. The focus of the study is on summer 2013 (June to August), during which the SALTRACE (Saharan Aerosol Long-range TRansport and Aerosol-Cloud interaction Experiment) field campaign also took place. It involves satellite observations by the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) flying on board the geostationary Meteosat Second Generation (MSG) satellite, which are analysed and used to infer a data set of active dust sources. The spatio-temporal distribution of dust source activation frequencies (DSAFs) allows for linking the diurnal cycle of dust source activations to dominant meteorological controls on dust emission. In summer, Saharan dust source activations clearly differ from dust source activations over the Sahel regarding the time of day when dust emission begins. The Sahara is dominated by morning dust source activations predominantly driven by the breakdown of the nocturnal low-level jet. In contrast, dust source activations in the Sahel are predominantly activated during the second half of the day, when downdrafts associated with deep moist convection are the major atmospheric driver. Complementary to the satellite-based analysis on dust source activations and implications from their diurnal cycle, simulations on atmosphere and dust life cycle were performed using the mesoscale atmosphere–dust model system COSMO-MUSCAT (COSMO: COnsortium for Small-scale MOdelling; MUSCAT: MUltiScale Chemistry Aerosol Transport Model). Fields from this simulation were analysed regarding the variability of the harmattan, the Saharan heat low, and the monsoon circulation as well as their impact on the variability of the Saharan dust outflow towards the North Atlantic. This study illustrates the complexity of the interaction among the three major circulation regimes and their modulation of the North African dust outflow. Enhanced westward dust fluxes frequently appear following a phase characterized by a deep SHL. Ultimately, findings from this study contribute to the quantification of the interannual variability of the atmospheric dust burden.

Full textAbstract:
The political participation of immigrants has received increased scholarly attention over recent decades. However, comparisons between the electoral behavior of immigrants in their countries of origin and of residence are still limited. This article addresses this gap in the literature and seeks to identify the determinants of Romanian immigrants' electoral participation in the local elections of four West European countries (Germany, France, Italy, and Spain) as compared to their turnout in their home country's legislative elections. Looking through the lenses of exposure theory, we hypothesize that contact with institutions, people, and values from the countries of residence are likely to have different effects in the two types of elections. We test the explanatory power of four main variables - time spent in the host country, social networks, degree of involvement in the local community, and the type of relationship with citizens of their host countries - to which we add a series of individual-level controls such as age, education, gender, and media exposure. To assess our claim, we employ binary logistic regression to analyze original web survey data collected in the summer of 2013. The result supports the empirical implications of exposure theory.

Full textAbstract:
SynopsisMatteuccia struthiopteris is distributed throughout most of the boreal region of the northern hemisphere. It has been variously recorded as a vermifuge and an ingredient in beer manufacture as well as a food. Young leaves, alternatively known as croziers or fiddleheads, are picked before they have unfurled and are boiled or steamed and served as a hot vegetable. The market, between Malecite indian and colonists, developed in the Fredericton area of New Brunswick 200 years ago, following a particularly severe winter. The newly arrived United Empire Loyalists, having emigrated from the United States, were so short of food that by the spring of 1784, they were reduced to eating any sort of provender nature could supply. Specific mention is made of fiddleheads, which became a traditional spring vegetable in New Brunswick. This market spread into Maine in the United States, particularly into those areas bordering the St John River. The present market is still predominantly in New Brunswick, where the wild harvest is between 150–200 t/yr, a yield which is approximately four times the harvest in neighbouring Maine. Food companies process about one third of the crop. In Maine, this is done by a single canning company in Wilton, whereas in New Brunswick, tinned fiddleheads have largely been superseded by the frozen product which is the monopoly of a company working in Florenceville. In addition, Canadian companies have recently sprung up which export the fresh spring vegetable in refrigerated lorries to larger centres west of the province. These companies account for less than a quarter of the harvest. The remainder is sold from either roadside stands, or to a wholesaler who distributes them to outlets in the region. The harvest is still predominantly done by natives. Much greater detail of both harvest, food preparation, and economic history is given by von Aderkas (1984). It has recently come to the author's attention that crowns of M. struthiopteris are sold also as a garden ornamental. Over 5000 plants/yr are sold by one Ontario distributor alone. Estimates from other nurseries in West Germany and the United States which do the same trade are presently unavailable.

Full textAbstract:
Background: Diode-assisted endodontics is nowadays utilized for pulp space disinfection, but little is known on the bonding potential of this lased root dentin when the tooth is restored with an intracanal polymer post. Objectives: to investigate the influence of diode laser irradiation settings, in laser-assisted endodontics, on the intraradicular bonding of composite materials. Methods: Sixteen two-rooted, maxillary first premolars were collected, prepared up to F4 (Protaper Universal. Dentsply-Maillefer, Ballaigues, Switzerland), and randomly assigned in two groups: group A (chopped mode or short pulse), diode irradiated according to protocol, pulse 25 ms, power 2.5 W, and group B (microchopped mode or ultrashort pulse), pulse 25 μs, peak power 12 W (both groups GentleRay. KaVo Dental, Biberach an der Riss, Germany). Buccal canals were irradiated, palatal ones served as controls. Canals were then obturated, post space was created in all canals, and quartz-fiber posts (ICE light Danville. Danville Materials, San Ramon, CA, USA) were cemented by self-etch self-curing cement (Max Cem Elite. Kerr, West Collins Orange, CA, USA) (Max Cem Elite. Kerr, Brea, CA, USA). A week later, teeth were sectioned horizontally in 1 mm increments. Push-out test was conducted in a Zwick testing machine (Zwick Roell, Ulm, Germany) at 1 mm/min speed, and the force required to dislodge the post from each specimen (F-max) was recorded. Weibull regression models were applied for statistical analyses. Results: Differences in F-max by group (control vs. chopped mode vs. microchopped mode) and height (meaning the apical-to-coronal position of each specimen along the root) were statistically significant (p < 0.05 in all cases). Conclusions: Short pulses (or chopped mode) had a profound positive effect on the quality of intraradicular bonding, while Ultrashort pulses (or microchopped mode) affected it negatively. In addition, apically positioned bonding proved weaker compared with more coronally located specimens.

The article analyzes the peculiarities of the current state of development of the economy of Ukraine. A review and assessment of the economic recovery of countries after military aggression was carried out. The key points in the formation of the recovery policy were highlighted on the example of the countries that were being rebuilt according to the Marshall Plan. The main directions of post-war recovery of countries such as Israel, South Korea, Japan, Italy, and West Germany were analyzed in detail and highlighted. It was established that, taking into account the fact that Ukraine has a powerful natural resource and intellectual and personnel potential, the main vectors in the direction of economic recovery for Ukraine in the post-war period are: the development of high technologies for production with high added value; forming the export orientation of the economy; development of infrastructural support, since Ukraine has a favorable geographical position, the development of the transport and communication structure will allow to develop the transit potential; use of intellectual and personnel potential in the development of high technologies, innovative production; activation due to state support of small business; changing the principles of implementing reforms of economic growth towards the activation of entrepreneurial initiatives and the attraction of foreign investors, while reducing the influence of the state on these processes; promoting the development of high-tech industries that use intellectual and innovative developments and have a high added value. The key directions for Ukraine were formed, which can be taken into account during recovery with adaptation to modern conditions of innovative development of the world economy. To determine the resource potential, the state and trends of the state’s economic development were analyzed over the last period according to certain characteristics. Conceptual bases for the formation of a strategy for the development and restoration of the state in the post-war period are proposed.

Full textAbstract:
This article, based on the archives stored in Estonia, Latvia, Lithuania, and Russia and some recently published documents, investigates the coup attempted by the Soviets on December 1, 1924 in Tallinn and evaluates its consequences within the broad context of international relations. During the research, it was established that an attempt to stage a coup in Estonia had been undertaken both by the Estonian communists and the USSR leadership, which had the highest political body – the Politburo – and the Comintern, a self-crafted tool set up for spreading the communist movement around the world, at its disposal. Thus, the revolution was masterminded by the Soviet authorities, whereas the Estonian communists were mainly responsible for its implementation. The task of the coup leadership was to seize power and hold on to it for some time, long enough to request that the USSR “renders support.” Preparations were underway for such support. This is evidenced by military preparations in the northern regions of the USSR and the territory near the Estonian border as well as by the deployment of Soviet ships in the vicinity of Tallinn and the activities of the Soviet embassy located in the capital. The attempted coup turned into a putsch due to the maximum conspiracy of their organizers. The conspiracy was brought about by the then-public awareness that the revolutionary events in Germany in 1923 had been instigated by the Soviets. The attempted coup in Estonia failed due to the extraordinary defensive operations put up by the Estonian authorities and power structures as well as due to the failure to involve the workers and the other strata of society in the coup.
Latvia, Estonia’s only ally, was the first country to stand by Estonia’s side after the country withstood the attempted coup. The lessons were learnt not only by these two countries but by Lithuania as well. They began taking adequate measures to stifle communist activities. Neither France nor England or any other Western state made plans to deploy their fleets to the Baltic Sea to support the Estonians or at least show, in a demonstrative way, their support in such a trying time. They also failed to hold any diplomatic démarches against the Soviets opposing the export of revolution practiced by the Soviets. Due to diplomatic pressure imposed by the USSR, Estonia could not publicly and officially name the actual organizers of the putsch. As a result, only the local communists were indiscriminately accused. Such forced tactics, if only indirectly, had at least partially been influencing the area of historical research as well.
However, the sudden and unequivocal liquidation of the putsch in Tallinn could have prompted the USSR to no longer expand its revolutionary export to the West, and the “abstinence” of such kind had lasted until the Second World War. The war itself and the previous collusion with Adolf Hitler made it possible for Stalin to cherish even greater ambitions to renew the spread of communism in other countries.

Abstract. Increasing dissolved organic carbon (DOC) concentrations and exports from headwater catchments impact the quality of downstream waters and pose challenges to water supply. The importance of riparian zones for DOC export from catchments in humid, temperate climates has generally been acknowledged, but the hydrological controls and biogeochemical factors that govern mobilization of DOC from riparian zones remain elusive. A high-frequency dataset (15 min resolution for over 1 year) from a headwater catchment in the Harz Mountains (Germany) was analyzed for dominant patterns in DOC concentration (CDOC) and optical DOC quality parameters SUVA254 and S275−295 (spectral slope between 275 and 295 nm) on event and seasonal scales. Quality parameters and CDOC systematically changed with increasing fractions of high-frequency quick flow (Qhf) and antecedent hydroclimatic conditions, defined by the following metrics: aridity index (AI60) of the preceding 60 d and the quotient of mean temperature (T30) and mean discharge (Q30) of the preceding 30 d, which we refer to as discharge-normalized temperature (DNT30). Selected statistical multiple linear regression models for the complete time series (R2=0.72, 0.64 and 0.65 for CDOC, SUVA254 and S275−295, resp.) captured DOC dynamics based on event (Qhf and baseflow) and seasonal-scale predictors (AI60, DNT30). The relative importance of seasonal-scale predictors allowed for the separation of three hydroclimatic states (warm and dry, cold and wet, and intermediate). The specific DOC quality for each state indicates a shift in the activated source zones and highlights the importance of antecedent conditions and their impact on DOC accumulation and mobilization in the riparian zone. The warm and dry state results in high DOC concentrations during events and low concentrations between events and thus can be seen as mobilization limited, whereas the cold and wet state results in low concentration between and during events due to limited DOC accumulation in the riparian zone. The study demonstrates the considerable value of continuous high-frequency measurements of DOC quality and quantity and its (hydroclimatic) key controlling variables in quantitatively unraveling DOC mobilization in the riparian zone. These variables can be linked to DOC source activation by discharge events and the more seasonal control of DOC production in riparian soils.

Summary Objectives: To assess the joint effect of smoking and alcohol consumption on laryngeal risk on tumor subsites. Methods: Population-based case-control study in South-West Germany with 257 histologically confirmed cases (236 males, 21 females), age 37 to 80 years, and 769 population controls (702 males, 67 females), 1:3 frequency matched by age and sex. Results: Half of the tumors (50.6%) were glottic or subglottic, 17.5% were supraglottic. Due to advanced stage, the subsite of 31.9% of the tumors could not be determined clearly. There is a strong increase in risk with increasing tobacco consumption with an odds ratio (OR) of 59.8 (95% confidence interval (CI) 21.3-167.3) for heavy smoking (>80 packyears (py)), all cases combined. In comparison to current smokers, cancer risk is reduced for ex-smoking (>2 years) OR=0.36, 95% CI 0.24-0.53. The risks were higher for supraglottic than for glottic and sub-glottic tumors. The effect of alcohol is not as strong. A significantly increased odds ratio of 2.0, 95% CI (1.0-3.9) results for 75-100 g ethanol/day only for glottic and subglottic tumors. The OR rises from 2.2, 95% CI (1.1-4.3) for 100-150 g ethanol/day to 4.3, 95% CI (1.4-13.2) for more than 150 g ethanol/day (all models adjusted for education). The joint effect of smoking and alcohol results appears sub-multiplicative but super-additive. Almost 90% of the tumors can be attributed to both factors. Conclusion: Contrary to earlier investigations we observed a sub-multiplicative effect of smoking and alcohol. The risk for persons with both high alcohol and tobacco consumption is extremely high which indicates the importance of intervention.

The purpose of the article is to define the place of Novomoskovsk in the international economic relations of Ukraine in the 1950s – 1980s, and main participants of these relations at the city level, directions, content and features. Research methods: historical-chronological, historical-genetic, comparative, descriptive. Main results. the article reveals the importance of Novomoskovsk, Dnipropetrovsk region, one of the small cities in the development of international economic relations of Ukraine as a part of the USSR. It is defined that the main factor that determined the place of Novomoskovsk in the international economic relations is the Novomoskovsk Pipe Plant activity. The role of the plant in these relations consisted of the production for export, business trips abroad, their admission to study and exchange experiences. The USSR, Ukraine in particular with its powerful industrial complex, played an important role in the reconstruction, formation, and development of the metallurgical industry in the countries of “people’s democracy” in Europe, Asia, countries whose governments were loyal to the USSR. The Novomoskovsk Pipe Plant and its employees contributed to the construction and operation of the first metallurgical complexes in Bulgaria and China. Since 1963, the enterprise has been one of the leaders in Ukraine and the USSR in the production of large diameter pipes for main gas and oil pipelines, which has strengthened its presence in the execution of export orders. The relations of the plant were not limited to the countries of the socialist camp, but also included countries with market economies. These relations were particularly influenced by political and ideological factors, as shown by the example of the USSR’s relations with West Germany, France and Japan. The Novomoskovsk Pipe Plant served as a base for holding international UN seminars on the training of metallurgical specialists, and its employees participated in international exhibitions, presenting the plant’s products. The course of the Cold War and international crises led to the appearance of a peculiar phenomenon of the Soviet era – the inclusion of production in propaganda campaigns, which were joined by groups of enterprises. From the side of the pipe plant, these were rallies in support (of Algeria, Cuba, Vietnam, etc.) and commitments on additional working days, increased production rates, early deadlines for implementation of plans, and the deduction of products in favor of support facilities. The importance of industrial relations for the development of the non-productive sphere is emphasized: contacts with foreigners in the city during business trips served as a window to the world, contributed to the expansion of worldview. In addition, with the help of people’s diplomacy there were formed trustworthy relationships between nations and people, which promoted the positive international image of the USSR in the best way possible. Practical significance: the results of the research can be used to form the theme of scientific research on regional, Ukrainian, world history of the second half of the 20th century implied into the practice of teaching relevant disciplines in higher education institutes, used to create / update museum exhibitions in Novomoskovsk. Scientific novelty: a significant part of published and unpublished sources on the topic of international economic relations of Novomoskovsk is generalized and processed for the first time, some of the sources are introduced into scientific circulation firstly and are interpreted considering the latest research on the history of the Cold War. Type of article: research.

Full textAbstract:
In July 2011, greenhouse-grown chrysanthemum hybrid plants (Chrysanthemum × morifolium) with symptoms resembling those associated with tospoviruses were observed in the Kupusina locality (West Bačka District, Serbia). Disease incidence was estimated at 40%. Symptomatic plants with chlorotic ring spots and line patterns were sampled and tested by double antibody sandwich (DAS)-ELISA using polyclonal antisera (Bioreba AG, Reinach, Switzerland) against the two of the most devastating tospoviruses in the greenhouse floriculture industry: Tomato spotted wilt virus (TSWV) and Impatiens necrotic spot virus (INSV) (2). Commercial positive and negative controls and extracts from healthy chrysanthemum tissue were included in each ELISA. TSWV was detected serologically in 16 of 20 chrysanthemum samples and all tested samples were negative for INSV. The virus was mechanically transmitted from ELISA-positive chrysanthemum samples to five plants each of both Petunia × hybrida and Nicotiana tabacum ‘Samsun’ using chilled 0.01 M phosphate buffer (pH 7) containing 0.1% sodium sulfite. Inoculated plants produced local necrotic spots and systemic chlorotic/necrotic concentric rings, consistent with symptoms caused by TSWV (1). The presence of TSWV in ELISA-positive chrysanthemum plants and N. tabacum‘Samsun’ was further confirmed by conventional reverse transcription (RT)-PCR. Total RNAs were extracted with an RNeasy Plant Mini Kit (Qiagen, Hilden, Germany). RT-PCR was performed with the One-Step RT-PCR Kit (Qiagen) using primers TSWVCP-f/TSWVCP-r specific to the nucleocapsid protein (N) gene (4). A Serbian isolate of TSWV from tobacco (GenBank Accession No. GQ373173) and RNA extracted from a healthy chrysanthemum plant were used as positive and negative controls, respectively. An amplicon of the correct predicted size (738-bp) was obtained from each of the plants assayed, and that derived from chrysanthemum isolate 529-11 was purified (QIAqick PCR Purification Kit, Qiagen) and sequenced (JQ692106). Sequence analysis of the partial N gene, conducted with MEGA5 software, revealed the highest nucleotide identity of 99.6% (99% amino acid identity) with 12 TSWV isolates deposited in GenBank originating from different hosts from Italy (HQ830186-87, DQ431237-38, DQ398945), Montenegro (GU355939-40, GU339506, GU339508), France (FR693055-56), and the Czech Republic (AJ296599). The consensus maximum parsimony tree obtained on a 705-bp partial N gene sequence of TSWV isolates available in GenBank revealed that Serbian TSWV isolate 529-11 from chrysanthemum was clustered in the European subpopulation 2, while the Serbian isolates from tomato (GU369723) and tobacco (GQ373172-73 and GQ355467) were clustered in the European subpopulation 1 denoted previously (3). The distribution of TSWV in commercial chrysanthemum crops is wide (2). To our knowledge, this is the first report of TSWV infecting chrysanthemum in Serbia. Since chrysanthemum popularity and returns have been rising rapidly, the presence of TSWV may significantly reduce quality of crops in Serbia. References: (1) Anonymous. OEPP/EPPO Bull. 34:271, 2004.

Full textAbstract:
In 2003 and 2004, soils in oak forest ecosystems in nine central and eastern states of the United States were surveyed for Phytophthora spp. Soil samples were collected around healthy and symptomatic trees. Symptoms included dieback of branches, gaps in lateral branch systems, yellowing of foliage, wilting and clustering of leaves, and the presence of epicormic shoots. Soil subsamples were collected in each of the four cardinal directions and at a distance of 1 to 2 m from the base of a tree. The four subsamples were bulked to produce a sample of approximately 2,000 ml. In the laboratory, each sample was mixed thoroughly and a single 250-g subsample was flooded with 500 ml of distilled water and baited with Quercus robur leaflets for 3 to 5 days at 17 to 20°C. Discolored leaflets were examined microscopically (×200) and those with sporangia typical of Phytophthora spp. were plated on PARPNH selective medium (1). Phytophthora europaea was recovered from soil samples collected from Q. alba in West Virginia, Q. rubra in Minnesota, West Virginia, and Wisconsin, Q. phellos in Ohio, and Q. velutina in Pennsylvania. Cultures were identified as P. europaea by their morphological, physiological, and molecular characteristics (4). Average dimensions of nine isolates were determined. Oogonia were 40 ± 3.9 μm in diameter and often had few bullet protuberances and tapered bases; oospores mostly filled the oogonia and averaged 36 ± 3.7 μm; sporangia dimensions averaged 42 ± 6.1 × 30 ± 4.1 μm with a length/width ratio of 1:4. Isolates produced larger oogonia and oospores but had similar sporangia length/width ratios comparable to the species description (4). Growth optimum (5.8 to 6.9 mm day-1) on V8 juice agar (V8A) occurred at 25°C. On potato dextrose agar, colonies produced dense, felt-like mycelia, often with a central mound of aerial hyphae. DNA also was extracted from eight representative isolates and the internal transcribed spacer (ITS) region of rDNA from each isolate was amplified and sequenced. ITS sequences were identical to those of P. europaea in the NCBI GenBank database (Accession No. DQ313222). Pathogenicity of six isolates (one from each site) was confirmed by wounding stems of 2-year-old Q. alba, Q. rubra, and Q. velutina seedlings and inoculating wounds with V8A plugs (6 mm) containing mycelia; V8A plugs without mycelia were used for controls. Two months after inoculation, P. europaea was reisolated on PARPNH medium from advancing lesions on all inoculated seedlings but was not isolated from control plants. Mean lesion lengths on seedlings inoculated with P. europaea were significantly greater (P < 0.05) than those on control plants; lesions averaged 0.46 cm on Q. alba, 1.38 cm on Q. rubra, and 1.01 cm on Q. velutina. Previously, P. europaea only was reported from oak trees and soil in forests of Austria, France, and Germany (1–4). These findings extend the current distribution of P. europaea and raise questions about its origin and role in the health of oak forests in eastern and north-central United States. Q. alba, Q. phellos, Q. rubra, and Q. velutina are new host associations for P. europaea. References: (1) Y. Balci and E. Halmschlager. For. Pathol. 33:157, 2003. (2) E. Hansen and C. Delatour. Ann.

Full textAbstract:
Since the late 1970s, chestnut (Castanea spp.) has been one of the most commonly cultivated nuts for human consumption in Korea. In 1998, as much as 100,000 t of chestnut seeds were produced from 79,000 ha of plantations for export (2). Most cultivated chestnuts are hybrids of Castanea crenata and C. mollissima that have resulted in 27 cultivars commonly grown in Korea. In 2004, dead trees of two cultivars (Tsukuba and Ginyose) from different locations were found with black ooze emanating from reddish, sunken tissues on the trunks. When the bark was peeled off, a distinct necrotic region was observed on the basal trunk with the discoloration extending up and girdling the trunk. In November 2006, a Phytophthora species was isolated from the necrotic areas with a CARP selective medium (4). Eleven isolates were obtained from three locations: Hadong, Hapcheon, and Youngqwang. The isolates produced numerous homothallic oogonia (34.0 to 46.2 × 21.9 to 26.7 μm) with warty protuberances on the surface. Antheridia were amphigynous with long, funnel-shaped stalks at the base of the oogonia. The formation of papillate, ovoid to obpyriform sporangia (17.0 to 38.9 × 14.6 to 29.2 μm) was induced by cold treatment in filtered (through 25-μm particle retention) creek water or deionized water. Chlamydospores were not observed. Comparison of the rDNA ITS sequence using ITS1/4 (3) showed 99.6% similarity to P. katsurae (GenBank Accession No. AF266771) with three base pair differences. All eleven isolates showed identical ITS sequences. Pathogenicity studies were conducted on excised three 15-cm-long × 5-cm-diameter logs from each of three chestnut cultivars (Moriwase, Parkmi 2, and Ibuki). Bark (5 mm in diameter) was taken with a cork borer on each log followed by inoculation with a 5-mm agar disk of two isolates, PH.K01 and PH.K07. The logs were placed in a moist chamber for 7 days. Noninoculated controls consisted of log sections from each cultivar treated with agar disks. The pathogencity test was repeated three times. The entire log of cv. Parkmi 2 became necrotic, whereas the other two cultivars developed only small lesions (P < 0.0001). The noninoculated control logs of each cultivar did not develop lesions and no pathogen was reisolated from them. This suggests that cultivars differ in susceptibility. P. katsurae (synonym = P. castaneae) was first described from Japan in 1931. P. cambivora, P. cinnamomi, and P. katsurae are commonly responsible for ink disease on chestnut species in Europe, the United States, and Asia (1). The impact of P. katsurae on chestnut production in Korea is currently unknown. References: (1) A. Boutard et al. The West. Chestnut. 3:6, 2001. (2) S. H. Lee et al. J. Korean For. Soc. 95:61, 2006.

Boxleaf veronica (Hebe buxifolia (Benth.) Cockayne & Allan), native to New Zealand, is an annual or perennial shrub widely cultivated in Mediterranean zones. During late spring 2003, after seasonably wet and cool weather, a downy mildew epidemic occurred on potted, overhead irrigated, 1-year-old seedlings at a commercial nursery in eastern Sicily (southern Italy). Infections affected boxleaf veronica at first, but spread to variegated boxleaf (H. buxifolia cv. variegata). Initial symptoms on the upper side of leaves were small, gray brown patches that gradually spread, eventually resulting in necrosis in the center of infected areas. At that point, brown patches were evident on both sides of the leaves. Lesions on the lower leaf surface became covered with a fairly dense, pale gray-to-brown layer of conidia and conidiophores. As the disease progressed, these spots coalesced into large and conspicuous brown lesions. The youngest, most succulent shoots withered and died. The large brown lesions on the leaves were disfiguring and affected 95 to 100% of plants in the nursery. All diseased nursery stock had to be discarded. Oospores were not observed in leaf tissues. The fungus recovered from leaves with abundant gray brown sporulation was identified as Peronospora grisea (Unger) Unger. Microscopic observations revealed conidiophores that branched dichotomously five to seven times with branch ends 6 to 10 × 2 to 3 μm, slightly curved, and tapered to a blunt apex. Hyaline conidia were ellipsoid, brownish when mature, and measured 23 to 27 × 15 to 18 μm (mean = 25.2 × 17.1 μm), falling within the range of those reported for P. grisea (1). Pathogenicity was confirmed by inoculating 10 1-yr-old seedlings (10 cm tall) by gently pressing infected leaves with abundant sporulation onto healthy leaves and maintaining inoculated plants in a humid chamber at 21°C. An equal number of noninoculated plants served as controls. After 9 to 11 days, symptoms similar to those originally observed developed onto inoculated plants, and after 12 to 15 days, grayish mildew grew on leaves. Microscopic examination of the developing mycelium confirmed that leaves were infected with P. grisea. Uninoculated control plants did not develop any symptoms. The disease was also confirmed in this way on variegated boxleaf veronica (H. buxifolia cv. variegata). Downy mildew of Hebe spp. has been recorded in New Zealand, Britain, France, Germany, and more recently, West Sussex (2). Heavy rainfall during the spring of 2003 in eastern Sicily could have favored disease development. To our knowledge, this is the first report of downy mildew of boxleaf veronica and variegated boxleaf veronica caused by P. grisea in Italy. References: (1) S. M. Francis and A. M. Berrie.

Abstract. The ability of seven state-of-the-art chemistry–aerosol models to reproduce distributions of tropospheric ozone and its precursors, as well as aerosols over eastern Asia in summer 2008, is evaluated. The study focuses on the performance of models used to assess impacts of pollutants on climate and air quality as part of the EU ECLIPSE project. Models, run using the same ECLIPSE emissions, are compared over different spatial scales to in situ surface, vertical profiles and satellite data. Several rather clear biases are found between model results and observations, including overestimation of ozone at rural locations downwind of the main emission regions in China, as well as downwind over the Pacific. Several models produce too much ozone over polluted regions, which is then transported downwind. Analysis points to different factors related to the ability of models to simulate VOC-limited regimes over polluted regions and NOx limited regimes downwind. This may also be linked to biases compared to satellite NO2, indicating overestimation of NO2 over and to the north of the northern China Plain emission region. On the other hand, model NO2 is too low to the south and west of this region and over South Korea/Japan. Overestimation of ozone is linked to systematic underestimation of CO particularly at rural sites and downwind of the main Chinese emission regions. This is likely to be due to enhanced destruction of CO by OH. Overestimation of Asian ozone and its transport downwind implies that radiative forcing from this source may be overestimated. Model-observation discrepancies over Beijing do not appear to be due to emission controls linked to the Olympic Games in summer 2008.With regard to aerosols, most models reproduce the satellite-derived AOD patterns over eastern China. Our study nevertheless reveals an overestimation of ECLIPSE model mean surface BC and sulphate aerosols in urban China in summer 2008. The effect of the short-term emission mitigation in Beijing is too weak to explain the differences between the models. Our results rather point to an overestimation of SO2 emissions, in particular, close to the surface in Chinese urban areas. However, we also identify a clear underestimation of aerosol concentrations over northern India, suggesting that the rapid recent growth of emissions in India, as well as their spatial extension, is underestimated in emission inventories. Model deficiencies in the representation of pollution accumulation due to the Indian monsoon may also be playing a role. Comparison with vertical aerosol lidar measurements highlights a general underestimation of scattering aerosols in the boundary layer associated with overestimation in the free troposphere pointing to modelled aerosol lifetimes that are too long. This is likely linked to too strong vertical transport and/or insufficient deposition efficiency during transport or export from the boundary layer, rather than chemical processing (in the case of sulphate aerosols). Underestimation of sulphate in the boundary layer implies potentially large errors in simulated aerosol–cloud interactions, via impacts on boundary-layer clouds.This evaluation has important implications for accurate assessment of air pollutants on regional air quality and global climate based on global model calculations. Ideally, models should be run at higher resolution over source regions to better simulate urban–rural pollutant gradients and/or chemical regimes, and also to better resolve pollutant processing and loss by wet deposition as well as vertical transport. Discrepancies in vertical distributions require further quantification and improvement since these are a key factor in the determination of radiative forcing from short-lived pollutants.

Full textAbstract:
<p><strong>Abstract.</strong> The Federal Agency for Cartography and Geodesy (BKG) in Germany is a technical agency under the Federal Ministry of the Interior, Building and Community (BMI). The organization consists of three departments namely Geoinformation, Geodesy and a Business Operations/Support department. Each department has multiple units which carry out their own respective duty in their field of subject. Tasks related to providing and homogenizing spatial data are located inside the geoinformation department. The main focus lies here on uniting the data collected by the federal states to form different types of nationwide datasets. The geodesy department focusses on real time satellite navigation systems, very long baseline interferometry and geodetic reference systems.</p><p>A recent development in the federal authorities has been the demand for quick maps and spatial data to support fast decision making processes. The BKG has established a complete workflow which allows for rapid data processing and the distribution to the respective customers. It is split into six sub processes with several branching options, processing and backpropagation steps. This allows for a systematic approach to covering the customer’s demand for spatial data and for the internal production chain. The workflow is backed up by a project management system, a quality management system and a production management system each covered in a handbook specially prepared to ensure consistency along the workflow.</p><p>The workflow gets started by the customer posing their request either via the service center (SC) unit, via mail or phone or through the controlling institution as a decree or an executive order. The first contact is crucial as important information is being exchanged and a rough concept of the demand is shaped. Once the actual task has reached the BKG a ticket number and an internal processing identifier will be assigned by the SC and the resource manager (RM) respectively. These unique keys will be used for the communication with the customer and additionally utilized as a tool for the administrative actions being carried out in the background. This action involves querying the license status of the customer which in addition determines the maximum cost of the task and the authorization of the data being used. In parallel the task, now referred to as a ticket, is being implemented in the project management system. Certain additional information will be assigned to the ticket like the project manager (PM) and the project processor. Once this step has been completed the working directory for the ticket will be created by using a predefined folder structure. This structure is composed of a data, export, communications and documentation folder. Depending on the nature of the ticket various preconfigured templates are at hand and will be used to ensure uniformity of the final products. If needed further communication with the customer is carried out. Data research is the last step in this part of the workflow (see figure 1).</p><p>The processing of the actual data makes up most of the workflow regarding time. Aspects like a uniform styleguide and quality controls by colleagues are performed alongside the work progress. If any non comforming aspect is found, the feedback is given directly to the person in charge of the ticket while also being mirrored in the project management system. Once the product is ready for deployment, final communication with the customer is executed. Additional changes stated by the customer can be implemented whereby an extra iteration of the quality process will be necessary. The data deployment is either carried out as a print product, a DVD, an OGC service or via a download option (see figure 2).</p><p>The final steps of the workflow involve the report of delivery to the service center, the creation of the cost report and the closure of the ticket in the project management system. The cost report is created in a semi-automatic process from data stored in the project management system and combined with the material cost report. It is then send via e-mail to the service center which will carry out any necessary invoice collections. Furthermore the internal data folder structure is cleaned up and a screenshot is taken of the product to use it as a subsidiary product in the dedicated online gallery of created products. Finally the closing information is relayed to the service center and the ticket gets closed (see figure 3). This whole workflow can be executed within several hours, days or weeks, depending on the deadline imposed by the customer or the event. Actual rapid mapping activations are done by multiple people simultaneously working on different steps of the previously explained workflow. This allows for fast response times and the accomplishment of the activation in time.</p>
