The transformation of agriculture in Ukraine: From collective farms to agroholdings. OSW Commentary No. 127, 06.02.2014

In recent years, Ukraine’s agriculture has been consistently improving and has been the only part of the country’s economy to buck the recession. According to preliminary estimates, in 2013 agricultural production increased by 13.7% - in contrast to a 4.7% decline in the industrial sector. According to official statistics, Ukraine’s industrial production was up 40% in the final months of 2013 when compared to the same period of 2012. This translated into an unexpected gain in fourth-quarter GDP growth (+3.7%) and prevented an annual drop in GDP. Crop production, and particularly the production of grain, hit a record high: in 2013, Ukraine produced 63 million tonnes of grain, outperforming its best ever harvest of 2011 (56.7 million tonnes). The value of Ukraine’s agricultural and food exports increased from US$4.3 billion in 2005 to US$17.9 billion in 2012, and currently accounts for a quarter of Ukraine’s total exports. Economic forecasts suggest that in the current marketing year (July 2013 - June 2014) Ukraine will sell more than 30 million tonnes of grain to foreign markets, making it the world’s second biggest grain exporter, after the United States.

Is there a way out of the Polish pickle? EPIN Commentary No. 31/22 January 2016

Poland is making headline news again. This time, however, not in a role of Central European Wunderkind surfing the economic crisis, but for reasons to be less proud of. Ever since the Prawo and Sprawiedliwość (PiS, a member of European Conservatives and Reformists group in the European Parliament) government took power after the elections in November, Poland has experienced political turmoil and is now facing accusations that the rule of law is in danger. This constitutes a major challenge for the European Union and for its other member states, which are looking for ways to deal with a recalcitrant state that makes a rapid U-turn on democratic fundamentals and takes any criticism hysterically. This is not the first time that the organisation has had to deal with such a case, yet solutions have not yet been found. Hungary is a case in point. And now Polish leaders too seem convinced about the virtues of the concept of illiberal democracy. Which prescription should the EU use to buck the trend and what are the potential side-effects?

Prospective longitudinal study of subcortical brain volumes in individuals at high familial risk of mood disorders with or without subsequent onset of depression

Subcortical volumetric brain abnormalities have been observed in mood disorders. However, it is unknown whether these reflect adverse effects predisposing to mood disorders or emerge at illness onset. Magnetic resonance imaging was conducted at baseline and after two years in 111 initially unaffected young adults at increased risk of mood disorders because of a close family history of bipolar disorder and 93 healthy controls (HC). During the follow-up, 20 high-risk subjects developed major depressive disorder (HR-MDD), with the others remaining well (HR-well). Volumes of the lateral ventricles, caudate, putamen, pallidum, thalamus, hippocampus and amygdala were extracted for each hemisphere. Using linear mixed-effects models, differences and longitudinal changes in subcortical volumes were investigated between groups (HC, HR-MDD, HR-well). There were no significant differences for any subcortical volume between groups controlling for multiple testing. Additionally, no significant differences emerged between groups over time. Our results indicate that volumetric subcortical brain abnormalities of these regions using the current method appear not to form familial trait markers for vulnerability to mood disorders in close relatives of bipolar disorder patients over the two-year time period studied. Moreover, they do not appear to reduce in response to illness onset at least for the time period studied.

(Table 2) Age determination of sediment cores from the Panama Basin

Application of the 230Th normalization method to estimate sediment burial fluxes in six cores from the eastern equatorial Pacific (EEP) reveals that bulk sediment and organic carbon fluxes display a coherent regional pattern during the Holocene that is consistent with modern oceanographic conditions, in contrast with estimates of bulk mass accumulation rates (MARs) derived from core chronologies. Two nearby sites (less than 10 km apart), which have different MARs, show nearly identical 230Th-normalized bulk fluxes. Focusing factors derived from the 230Th data at the foot of the Carnegie Ridge in the Panama Basin are >2 in the Holocene, implying that lateral sediment addition is significant in this part of the basin. New geochemical data and existing literature provide evidence for a hydrothermal source of sediment in the southern part of the Panama Basin and for downslope transport from the top of the Carnegie Ridge. The compilation of core records suggests that sediment focusing is spatially and temporally variable in the EEP. During oxygen isotope stage 2 (OIS 2, from 13-27 ka BP), focusing appears even higher compared to the Holocene at most sites, similar to earlier findings in the eastern and central equatorial Pacific. The magnitude of the glacial increase in focusing factors, however, is strongly dependent on the accuracy of age models. We offer two possible explanations for the increase in glacial focusing compared to the Holocene. The first one is that the apparent increase in lateral sediment redistribution is partly or even largely an artifact of insufficient age control in the EEP, while the second explanation, which assumes that the observed increase is real, involves enhanced deep sea tidal current flow during periods of low sea level stand.

Description and chemical composition of manganese nodules in a core located in the Nares Abyssal Plain, Atlantic Ocean

Three nodules from a core taken north of Puerto Rico are composed chiefly of an x-ray amorphous, hydrated, iron-manganese oxide, with secondary goethite, and minor detrital silicates incorporated during growth of the nodules. No primary manganese mineral is apparent. The nodules are enriched in iron and depleted in manganese relative to Atlantic Ocean averages. The formation of these nodules appears to have been contemporary with sedimentation and related to volcanic activity.

Novel multiple sclerosis susceptibility loci implicated in epigenetic regulation.

We conducted a genome-wide association study (GWAS) on multiple sclerosis (MS) susceptibility in German cohorts with 4888 cases and 10,395 controls. In addition to associations within the major histocompatibility complex (MHC) region, 15 non-MHC loci reached genome-wide significance. Four of these loci are novel MS susceptibility loci. They map to the genes L3MBTL3, MAZ, ERG, and SHMT1. The lead variant at SHMT1 was replicated in an independent Sardinian cohort. Products of the genes L3MBTL3, MAZ, and ERG play important roles in immune cell regulation. SHMT1 encodes a serine hydroxymethyltransferase catalyzing the transfer of a carbon unit to the folate cycle. This reaction is required for regulation of methylation homeostasis, which is important for establishment and maintenance of epigenetic signatures. Our GWAS approach in a defined population with limited genetic substructure detected associations not found in larger, more heterogeneous cohorts, thus providing new clues regarding MS pathogenesis.
