The Role of State Corporations in Redesign of Sectoral Supply Chain Management

The article discusses the problem of supply chain management in economy of Russian Federation. The institutional analysis revealed a trend towards the restoration of the supply chain management system that operated during the Soviet period on the basis of a transition to the manual economy management mode. The modern system of supply chain management of Russia has a number of differences from the Soviet model such as market pricing and distribution channels of the product, and it designed to implement the policy of import substitution in the Russian economy. The state corporation was chosen as the most appropriate organizational form to solve amassed structural problems. High risks of investing to the Russian economy, insecurity of private property rights, monopolization of certain sectors of the economy are creating an unfavorable institutional environment for business. Under these conditions, instead of expanding and encouraging the activities of private entrepreneurs, the state chose a different way to solve the structural problems of the Russian economy - withdrawing funds through taxes and distributing them through budgets of all levels to state corporations that are headed by the persons closest to power. The article shows that this path led to the restoration of the supply chain management system that was very characteristic to the Soviet economy. Since the experience of such management turned out to be negative, its repetition in the new market conditions is unlikely to bring a positive result, however, the government’s strategy does not provide for the possibility of replacing budget investments with private ones, as a result of which budget investments increasingly dominate, private investments are reduced, capital outflow is increasing, and the economy remains inefficient

Helioseismology space and ground-based studies

We give a preliminary report on the observations of solar irradiance fluctuations with the DIFOS photometer aboard the Russian–Ukrainian satellite CORONAS-F launched in 2001. In addition, the parallel ground-based spectral observations (VTT, Tenerife) carried out with 20-day observing space campaign are described

Brain structural correlates of insomnia severity in 1053 individuals with major depressive disorder : results from the ENIGMA MDD Working Group

It has been difficult to find robust brain structural correlates of the overall severity of major depressive disorder (MDD). We hypothesized that specific symptoms may better reveal correlates and investigated this for the severity of insomnia, both a key symptom and a modifiable major risk factor of MDD. Cortical thickness, surface area and subcortical volumes were assessed from T1-weighted brain magnetic resonance imaging (MRI) scans of 1053 MDD patients (age range 13-79 years) from 15 cohorts within the ENIGMA MDD Working Group. Insomnia severity was measured by summing the insomnia items of the Hamilton Depression Rating Scale (HDRS). Symptom specificity was evaluated with correlates of overall depression severity. Disease specificity was evaluated in two independent samples comprising 2108 healthy controls, and in 260 clinical controls with bipolar disorder. Results showed that MDD patients with more severe insomnia had a smaller cortical surface area, mostly driven by the right insula, left inferior frontal gyrus pars triangularis, left frontal pole, right superior parietal cortex, right medial orbitofrontal cortex, and right supramarginal gyrus. Associations were specific for insomnia severity, and were not found for overall depression severity. Associations were also specific to MDD; healthy controls and clinical controls showed differential insomnia severity association profiles. The findings indicate that MDD patients with more severe insomnia show smaller surfaces in several frontoparietal cortical areas. While explained variance remains small, symptom-specific associations could bring us closer to clues on underlying biological phenomena of MDD

CF3-Carbenoid functionalization of N-(pyrimidin-2-yl)indole catalyzed by cobalt complexes: Ligand control of selectivity

The carbonyl cobalt complex Cp*Co(CO)I2 catalyzes carbenoid Co alkylation of N-(pyrimidin-2-yl)indole with methyl 3,3,3-trifluoro-2-diazopropionate regioselectively giving 2-substituted indole, while the N,N’-ligated cations [CpCo(L)I]+ (L = bipy, phen) provide 3-substitution exclusively. The structure of [CpCo(phen)I]PF6 was investigated by X-ray diffraction.[Figure presented] © 201

Fluorine-containing ruthenium-based olefin metathesis catalysts

The review summarizes literature data on the methods for the introduction of fluorine atoms and fluoralkyl groups into different ligands to construct metathesis-active ruthenium carbene complexes. It also analyzes the influence of fluorinated ligands on the catalytic activity of the complexes. The choice, structure and positions of fluorinated substituents in NHC ligands are generally dictated by the desire to increase the electrophilicity of the ruthenium atom due to the electron-withdrawing effect of fluorine atoms and fluoroalkyl groups, resulting, as a rule, in an increase in the activity of the ruthenium complex. In catalysts with unsymmetrical fluorine-containing NHC ligands, there is a possibility of additional Ru-F coordination, making the complexes much more stable and, consequently, more active. The presence of fluorine in chelating alkylidene ligands provides an increase in the catalyst initiation rate due to a weakening of the ruthenium - heteroatom bond. Besides, the introduction of polyfluoroalkyl groups into ligands solves the problem of catalyst recovery using fluorous biphasic systems for reuse
