Abstract

The aim of the study is to compare behavioral and EEG reactions in Turkic-speaking inhabitants of Siberia (Tuvinians and Yakuts) and Russians during the recognition of syntax errors in native and foreign languages. Sixty-three healthy aboriginals of the Tyva Republic, 29 inhabitants of the Sakha (Yakutia) Republic, and 55 Russians from Novosibirsk participated in the study. EEG were recorded during execution of error-recognition task in Russian and English language (in all participants) and in native languages (Tuvinian or Yakut Turkic-speaking inhabitants). Reaction time (RT) and quality of task execution were chosen as behavioral measures. Amplitude and cortical distribution of P300 and P600 peaks of ERP were used as a measure of speech-related brain activity. In Tuvinians, there were no differences in the P300 and P600 amplitudes as well as in cortical topology for Russian and Tuvinian languages, but there was a difference for English. In Yakuts, the P300 and P600 amplitudes and topology of ERP for Russian language were the same as Russians had for native language. In Yakuts, brain reactions during Yakut and English language comprehension had no difference, while the Russian language comprehension was differed from both Yakut and English. We found out that the Tuvinians recognized both Russian and Tuvinian as native languages, and English as a foreign language. The Yakuts recognized both English and Yakut as foreign languages, but Russian as a native language. According to the inquirer, both Tuvinians and Yakuts use the national language as a spoken language, whereas they do not use it for writing. It can well be a reason that Yakuts perceive the Yakut writing language as a foreign language while writing Russian as their native., {"references":["S.

Abstract

EEG correlates of mathematical and trait anxiety level were studied in 52 healthy Russian-speakers during execution of error-recognition tasks with lexical, arithmetic and algebraic conditions. Event-related spectral perturbations were used as a measure of brain activity. The ERSP plots revealed alpha/beta desynchronizations within a 500-3000 ms interval after task onset and slow-wave synchronization within an interval of 150-350 ms. Amplitudes of these intervals reflected the accuracy of error recognition, and were differently associated with the three conditions. The correlates of anxiety were found in theta (4-8 Hz) and beta2 (16- 20 Hz) frequency bands. In theta band the effects of mathematical anxiety were stronger expressed in lexical, than in arithmetic and algebraic condition. The mathematical anxiety effects in theta band were associated with differences between anterior and posterior cortical areas, whereas the effects of trait anxiety were associated with inter-hemispherical differences. In beta1 and beta2 bands effects of trait and mathematical anxiety were directed oppositely. The trait anxiety was associated with increase of amplitude of desynchronization, whereas the mathematical anxiety was associated with decrease of this amplitude. The effect of mathematical anxiety in beta2 band was insignificant for lexical condition but was the strongest in algebraic condition. EEG correlates of anxiety in theta band could be interpreted as indexes of task emotionality, whereas the reaction in beta2 band is related to tension of intellectual resources., {"references":["M.

Abstract

Cannabinoids are known to regulate inhibitory synaptic transmission via activation of presynaptic G protein-coupled cannabinoid CB1 receptors (CB1Rs). Additionally, recent studies suggest that cannabinoids can also directly interact with recombinant GABAA receptors (GABAARs), potentiating currents activated by micromolar concentrations of γ-aminobutyric acid (GABA). However, the impact of this direct interaction on GABAergic inhibition in central nervous system is unknown. Here we report that currents mediated by recombinant GABAARs activated by high (synaptic) concentrations of GABA as well as GABAergic inhibitory postsynaptic currents (IPSCs) at neocortical fast spiking (FS) interneuron to pyramidal neuron synapses are suppressed by exogenous and endogenous cannabinoids in a CB1R-independent manner. This IPSC suppression may account for disruption of inhibitory control of pyramidal neurons by FS interneurons. At FS interneuron to pyramidal neuron synapses, endocannabinoids induce synaptic low-pass filtering of GABAAR-mediated currents evoked by high-frequency stimulation. The CB1R-independent suppression of inhibition is synapse specific. It does not occur in CB1R containing hippocampal cholecystokinin-positive interneuron to pyramidal neuron synapses. Furthermore, in contrast to synaptic receptors, the activity of extrasynaptic GABAARs in neocortical pyramidal neurons is enhanced by cannabinoids in a CB1R-independent manner. Thus, cannabinoids directly interact differentially with synaptic and extrasynaptic GABAARs, providing a potent novel context-dependent mechanism for regulation of inhibition., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

In the era of transformations the financial factors can be prejudiced and the market value of the company does not reflect its fundamental value it is important to scrutinize other "resources" of the firm, to define, the non-financial basis for growth. And according to the Knowledge management approach, we can regard the Intellectual Capital (IC) of the Firm as an estimation basis for growth of these resources. The strategic changes models of large companies tend to be the context items, i. e. depending from the various key components. The value as the result of constant strategic changes becomes the complicated intellectual parameter, which is managed and defined by the multi-level combination of interactions of different groups of stakeholders. Accordingly the authors of the article make an attempt to consider the Intellectual Value Based Management concept. At a whole this article covers the results of the research of the Intellectual value of the large Russian companies. Particularly the authors use the panel data to investigate the different growth factors of the intellectual value. According to the topic of the research, the authors analyze the potential for growth of large Russian trading companies through evaluation of its Intellectual Capital. The main idea of the research was to compare the contribution of fundamental and non-fundamental factors (that is, companies IC) which create the company Value proposition. And the main hypothesis was: the components of the company IC create more value than fundamental factors. The empirical study included the analysis of panel data regarding fundamental factors (e.g. Sales, Return on Assets) and such components of IC as Human Capital, Process Capital, Client Capital, Innovation Capital and Network Capital. The authors use a range of proxy variables (the so-called subcomponents of IC) to assess the contribution of each component of IC to the process of company value creation. The groups of proxy variables were the following: the existence and the efficiency of corporative training programs for employees; the efficiency of assets usage; the mature and the structure of the Board of directors; the process capital; measures for future growth; the client capital; relations with the stakeholders. To clarify the crucial idea of the research it is necessary to regard each sub-component of IC. The research covered three time periods (five years period, six years period, one forecasted cross-section). Due to the fact that Russian market could not be named among world highly investigated markets it is of great importance to scrutinize it through the analysis of the Intellectual capital accrued in the corporative sector of the economy. The results of this research can be used to explain some phenomena of Russian market development, and the research model can be used to evaluate the potential for growth of different companies (in primary importance - the potential of developing countries which tend to be "a locomotive" for the further recovery of the World economy). According to the results the main drivers for company's growth are factors of the following groups of proxy variables: the existence and the efficiency of corporative training programs for employees; the efficiency of assets usage; the process capital; measures for future growth; the client capital; relations with the stakeholders. The main hypothesis of the research was accepted, and consequently the authors proved through the empirical analysis that the components of IC create more value and can be regarded as growth drivers for the long-term development of the company and the creation of the sustainable competitive advantage.

Abstract

Intellectual capital and its components can be regarded as the source for a company's organic growth to maintain sustainable development. Under the crisis conditions most of financial reserves are unavailable; the inner organizational efficiency by means of intellectual capital is a question of survival edge for most of the large companies of emerging markets. Multidirectional trends of the development of BRIC economies played a significant role in this discussion and the issue became more complicated under the pressure of the crisis. Notwithstanding BRIC countries can be regarded as leaders of so-called developing economies. In terms of the downturn, however, the problem of the crisis should not be overstated: due to the cyclical changes of the world economy the stagnation will be rearranged by upturn sooner or later, however the accumulation of intellectual capital is the over time process. Intellectual capital of the company and its components can be regarded as "latent reserves" of the long term value growth. Intellectual capital is the "intangible safety-cushion" and it can be used only by those companies who have created it years before and therefore have focused on sustainable development. The research of intellectual capital components and its role in value creation and building competitive advantage can remain an actual topic for empirical investigations, carried out in various countries and by different research centers. The intellectual value of a company is a part of the total value, created through the process of the intellectual components' accumulation. The main goal of this research is to evaluate by means of the panel data analysis the influence of particular components of intellectual capital on the intellectual value of BRIC companies. The process of intellectual capital accumulation is over time and it can be measured according to the long run panel data analysis not less than 5 years. The panel data analysis revealed that the human capital can be considered the key factor of the long-term growth of BRIC companies of all industries. Employees and their competencies are this basis which is undervalued currently whereas most of financial assets lost trust and its value. However, specified directions of internal reserves audit and discussion of the Intellectual value on the emerging markets are very close to the fact that large BRIC companies depend a lot on the specific features of the infrastructure of each developing country. India and Russia are countries with the industrial potential, which is not fully realized, e.g. a lot of Russian companies are underinvested with unbalanced development strategies. Decrepit and out-of-date production facilities, in turn capital expenditures are a matter of great importance. The capital expenditures together with innovative managers and management techniques tend to be the leverage, which can push these companies towards intensive development, especially Russian companies.
