An economy with unrealistic indicators: an evaluation of the economic situation in Belarus and a forecast for 2013. OSW Commentary No. 103, 2013-02-20

The macroeconomic results achieved by Belarus in 2012 laid bare the weakness and the inefficiency of its economy. Belarus’s GDP and positive trade balance were growing in the first half of last year. However, this trend was reversed when Russia blocked the scheme of extremely lucrative manipulations in the re-export of Russian petroleum products by Belarus and when the demand for potassium fertilisers fell on the global market. It became clear once again that the outdated Belarusian model of a centrally planned economy is unable to generate sustainable growth, and the Belarusian economy needs thorough structural reforms. Nevertheless, President Alyaksandr Lukashenka consistently continues to block any changes in the system and at the same time expects that the economic indicators this year will reach levels far beyond the possibilities of the Belarusian economy. Therefore, there is a risk that the Belarusian government may employ – as they used to do – instruments aimed at artificially stimulating domestic demand, including money creation. This may upset the relative stability of state finances, which the regime managed to achieve last year. The worst case scenario would see a repeat of what happened in 2011, when a serious financial crisis occurred, forcing Minsk to make concessions (including selling the national network of gas pipelines) to Moscow, its only real source of loans. It thus cannot be ruled out that also this time the only way to recover from the slump will be to receive additional loan support and energy subsidies from Russia at the expense of selling further strategic companies to Russian investors.

Public feeling in Ukraine ahead of the parliamentary election. OSW Commentary No. 89, 2012-07-12

After two and a half years under President Viktor Yanukovych and the Party of Regions, the overwhelming majority of Ukrainians are dissatisfied with the state the country’s economy is currently in and the direction it has been developing in. There has also been a significant drop in stability and social security with the general public increasingly feeling that the government has little interest in their problems. Only 16% of Ukrainians believe that the current government has performed better than their predecessors, although overall confidence in both the ruling party and the opposition remains low. Nonetheless, falling support for the president and the Cabinet does not seem to have translated into greater popularity for the country’s opposition parties; these currently enjoy the confidence of only a quarter of the electorate. The clear lack of credibility for politicians on either side of the political spectrum, coupled with an almost universal preoccupation with the bare necessities of life, has shifted the political processes in Ukraine further down the agenda for the majority of Ukrainians. Ukraine’s poor economic performance, which over the last two years has been addressed through a series of highly unpopular economic reforms, has resulted in a growing mood of discontent and increased civil activity, with the Ukrainian people reporting a greater willingness than ever to join protests on social issues. Most of them, however, have shown much less interest in political rallies. This is likely to stem from low levels of trust in the opposition and the general belief that opposition politicians are not a viable alternative to the current government. One may therefore assume that there will be little public scrutiny of the parliamentary election scheduled for 28 October, and that the likelihood of mass demonstrations during it is low. However, in the event of large-scale vote rigging and a dismissive response from the government, spontaneous unsanctioned rallies cannot be ruled out. What is more likely, however, is a series of protests after the elections, when the already difficult economic situation is further exacerbated by a predicted rise in the price of gas for Ukrainian households and a possible move to devalue the Ukrainian hryvnia.

Turkey: has the AKP ended its winning streak? OSW Commentary No. 117, 2013-10-07

Since the conservative Justice and Development Party (AKP) took power in Turkey in 2002, it has enjoyed a constant winning streak: it won each election (with a support level of 49.83% in 2011), subordinated the army (which had de facto stood above the civilian government) and was reforming the country. The situation in the country was stable (especially when compared to the crises and restlessness in the 1990s), the economy was booming, Turkey’s position in regional politics was strengthening, and Ankara’s significance on the international arena was growing. This encouraged the ruling class to make long-term plans, leading up to the hundredth anniversary of the republic in 2023. In the coming decade, Turkey governed by the AKP was to become one of the global economic and political centres, a full member of the EU and at the same time a political and economic leader in the Middle East. However, the negative trends in the situation both domestically (mass public protests, the deadlocked Kurdish issue and the unsuccessful attempt to amend the constitution) and abroad (the war in Syria and the coup in Egypt) seen over the past few months have laid bare the limitations of the AKP’s rule and have affected the government’s democratic mandate, prestige and credibility on the international arena, as well as peace and order and domestic security. When compared to the beginning of 2013, the way the situation will develop in Turkey is at this moment definitely less predictable; and the possible scenarios include both relative peace (however, with socio-political tension present in the background) and the threat of destabilisation. Therefore, although the AKP will still remain the sole major political force, this party will have to face challenges which will decide not only its political future but also the directions the country will be developing in. However, a comprehensive solution of the accumulated problems and a simple return to the status quo ante, convenient to the government, seem unlikely in the foreseeable future.

Type A aortic dissection model to improve endovascular research and technologies.

OBJECTIVE Type A aortic dissection is a life-threatening disease requiring immediate surgical treatment. With emerging catheter-based technologies, endovascular stent-graft implantation to treat aneurysms and dissections has become a standardized procedure. However, endovascular treatment of the ascending aorta remains challenging. Thus we designed an ascending aortic dissection model to allow simulation of endovascular treatment. METHODS Five formalin-fixed human aortas were prepared. The ascending aorta was opened semicircularly in the middle portion and the medial layer was separated from the intima. The intimal tube was readapted using running monofilament sutures. The preparations were assessed by 128-slice computed tomography. A bare-metal stent was implanted for thoracic endovascular aortic repair in 4 of the aortic dissection models. RESULTS Separation of the intimal and medial layer of the aorta was considered to be sufficient because computed tomography showed a clear image of the dissection membrane in each aorta. The dissection was located 3.9 ± 1.4 cm proximally from the aortic annulus, with a length of 4.6 ± 0.9 cm. Before stent implantation, the mean distance from the intimal flap to the aortic wall was measured as 0.63 ± 0.163 cm in the ascending aorta. After stent implantation, this distance decreased to 0.26 ± 0.12 cm. CONCLUSION This model of aortic dissection of the ascending human aorta was reproducible with a comparable pathological and morphological appearance. The technique and model can be used to evaluate new stent-graft technologies to treat type A dissection and facilitate training for surgeons.

Enriching plant diversity in grasslands by large-scale experimental sward disturbance and seed addition along gradients of land-use intensity

Aims The relationship between biodiversity and ecosystem functioning is among the most active areas of ecological research. Furthermore, enhancing the diversity of degraded ecosystems is a major goal in applied restoration ecology. In grasslands, many species may be locally absent due to dispersal or microsite limitation and may therefore profit from mechanical disturbance of the resident vegetation. We established a seed addition and disturbance experiment across several grassland sites of different land use to test whether plant diversity can be increased in these grasslands. Additionally, the experiment will allow us testing the consequences of increased plant diversity for ecosystem processes and for the diversity of other taxa in real-world ecosystems. Here we present details of the experimental design and report results from the first vegetation survey one year after disturbance and seed addition. Moreover, we tested whether the effects of seed addition and disturbance varied among grassland depending on their land use or pre-disturbance plant diversity. Methods A full-factorial experiment was installed in 73 grasslands in three regions across Germany. Grasslands were under regular agricultural use, but varied in the type and the intensity of management, thereby representing the range of management typical for large parts of Central Europe. The disturbance treatment consisted of disturbing the top 10 cm of the sward using a rotavator or rotary harrow. Seed addition consisted of sowing a high-diversity seed mixture of regional plant species. These species were all regionally present, but often locally absent, depending on the resident vegetation composition and richness of each grassland. Important findings One year after sward disturbance it had significantly increased cover of bare soil, seedling species richness and numbers of seedlings. Seed addition had increased plant species richness, but only in combination with sward disturbance. The increase in species richness, when both seed addition and disturbance was applied, was higher at high land-use intensity and low resident diversity. Thus, we show that at least the early recruitment of many species is possible also at high land-use intensity, indicating the potential to restore and enhance biodiversity of species-poor agricultural grasslands. Our newly established experiment provides a unique platform for broad-scale research on the land-use dependence of future trajectories of vegetation diversity and composition and their effects on ecosystem functioning.

A 300 kyr record of upwelling off Oman during the Late Quaternary: evidence of the Asian southwest monsoon

In the northwest Arabian Sea upwelling occurs each summer, driven by the strong SW monsoon winds. Upwelling results in high biological productivity and a distinctive assemblage of plankton species in the surface waters off Oman that are preserved in the sediments along the Oman continental margin, creating a geologic record of monsoon-driven upwelling. Sediments recovered from the Oman continental margin during Ocean Drilling Program leg 117 provide an opportunity to examine how upwelling has varied during the late Quaternary, spanning a longer interval than piston cores recovered prior to the ODP cruise. Variations in foraminifer shell accumulation and in the relative abundance of Globigerina bulloides indicate dominant cycles of variation at 1/100 kyr, the dominant frequency of glacial-interglacial variations, and at 1/23 kyr, the frequency of precessionally driven cycles in seasonal insolation. The strongest monsoon winds (indicated by increased upwelling) occurred during interglacial times when perihelion was aligned with the summer solstice, an orbital change that increased the insolation received during summer in the northern hemisphere. During glacial times upwelling was reduced, and although the precessional cycles were still present their amplitude was smaller. At both frequencies the upwelling cycles are in phase with minimum ice volume, evidence that glacial-interglacial climate changes also include changes to the climate system that influence the low-latitude monsoon. We attribute the decrease in the monsoon winds observed during glacial times to changes in bare land albedo over Asia and/or to changes in the areal extent and seasonal cycle in Asian snow cover that decrease the summer land-sea temperature contrast. Other mechanisms may also be involved. These new upwelling time series differ substantially from previous results, however the previous work relied on cores located farther offshore where upwelling is less intense and other physical mechanisms become important. Our results support the observations derived from atmospheric general circulation models of the atmosphere that indicate that both glacial boundary conditions, and the strength of summer insolation are important variables contributing to cycles in the monsoon winds during the late Quaternary.

Plant species, biomass and environmental characteristics of relevés along the North America Arctic bioclimate gradient

Question: How do interactions between the physical environment and biotic properties of vegetation influence the formation of small patterned-ground features along the Arctic bioclimate gradient? Location: At 68° to 78°N: six locations along the Dalton Highway in arctic Alaska and three in Canada (Banks Island, Prince Patrick Island and Ellef Ringnes Island). Methods: We analysed floristic and structural vegetation, biomass and abiotic data (soil chemical and physical parameters, the n-factor [a soil thermal index] and spectral information [NDVI, LAI]) on 147 microhabitat releves of zonalpatterned-ground features. Using mapping, table analysis (JUICE) and ordination techniques (NMDS). Results: Table analysis using JUICE and the phi-coefficient to identify diagnostic species revealed clear groups of diagnostic plant taxa in four of the five zonal vegetation complexes. Plant communities and zonal complexes were generally well separated in the NMDS ordination. The Alaska and Canada communities were spatially separated in the ordination because of different glacial histories and location in separate floristic provinces, but there was no single controlling environmental gradient. Vegetation structure, particularly that of bryophytes and total biomass, strongly affected thermal properties of the soils. Patterned-ground complexes with the largest thermal differential between the patterned-ground features and the surrounding vegetation exhibited the clearest patterned-ground morphologies.

Concentrations and isotopic compositions of low molecular weight hydrocarbons in hydrothermal fluids from ODP Field, Middle Valley, northern Juan de Fuca Ridge

The presence of sedimentary organic matter blanketing midocean ridge crests has a potentially strong impact on metal transport in hydrothermal vent fluids. To constrain the role of organic matter in metal mobility during hydrothermal sediment alteration, we reacted organic-rich diatomaceous ooze from Guaymas Basin, Gulf of California, and organic-poor hemipelagic mud from Middle Valley, northern Juan de Fuca Ridge, with seawater and a Na-Ca-K-Cl fluid of seawater chlorinity, at 275° to 400°C, 350 to 500 bars, and initial fluid: sediment mass ratios ranging from 1.6 to 9.8. Reaction of these fluids with both sediment types released CO2 and high concentrations of ore-forming metals (Fe, Mn, Zn, Pb) to solution. Relatively low concentrations of Cu were observed in solution and likely reflect the reducing conditions that resulted from the presence of sedimentary organic matter. Both the concentrations of CO2 and dissolved metals were lower in fluids reacted with Middle Valley sediment compared with aqueous concentrations in fluids reacted with Guaymas Basin sediment. During alteration of both sediment types, metal concentrations varied strongly as a function of temperature, increasing by up to an order of magnitude over the 75°C range of each experiment. Major element fluid chemistry and observed alteration assemblages suggest that during hydrothermal alteration of organic-lean sediment from Middle Valley a feldspar-quartz-illite mineral assemblage buffered in situ pH. In contrast, data from the experimental alteration of organic-rich Guaymas Basin sediment suggest that a calcite-plagioclase-quartz assemblage regulated in situ pH. Fluid speciation calculations suggest that in situ pH during Guaymas Basin sediment alteration was lower than during alteration of Middle Valley sediment and accounts for the substantially greater metal mobility at a given temperature and pressure during the former experiment. Comparison of our results with the results of basalt alteration experiments indicate that except for Cu, hydrothermal sediment alteration results in equal or greater concentrations of ore-forming metals at a given temperature and pressure. Accordingly, the presence of ore-forming metals in fluids currently venting from sediment-covered hydrothermal systems at concentrations substantially lower than in fluids from bare-rock systems may reflect chemical reequilibration during subsurface cooling within the sediment pile.
