The role of perceived cultural distance in the acculturation of exchange students in Russia

This study is the first to address processes of psychological acculturation by exchange students in Russia. Using a sample of 168 exchange students in Moscow from China, North Korea, and countries in sub-Saharan Africa and in the former Soviet Union, the hypothesis was confirmed that a larger perceived cultural distance between mainstream and immigrant culture is associated with less psychological and sociocultural adaptation. The Chinese and North-Korean group reported to experience the largest perceived cultural distance and the lowest levels of adjustment, while the groups from the former USSR and (to a slightly lesser extent) Africa reported the smallest perceived cultural distance and the highest levels of adjustment. The results of a stepwise regression analysis showed that antecedent variables (perceived cultural distance, home and host domain resources, and personality) showed somewhat stronger associations with outcome variables (self-esteem, stress, and behavior in the home and the host domain) than did intervening variables (acculturation attitudes and coping)

The simulation has been carried out using recently developed HTSC microwave software, Vendik and Kollberg (1), comparing the results with commercially available software (Microwave and RF Design Systems (mds) from Hewlett Packard, and Microwave Harmnonica (MH) from Compact Software). Problems limiting narrow-band microstrip filter development at millimeter wavelengths are studied and discusse

The role of perceived ethnic vitality in acculturation among Russian, emigrants of france, germany, and the Netherlands

This study addressed the role of perceived ethnic vitality in acculturation among Russian emigrants to France (N= 229), Germany (N = 240), and the Netherlands (N = 182). Support was found for the hypothesis that Russian emigrants to France whose community has a high perceived ethnic vitality showed more psychological adjustment and more interactions with co-nationals and host nationals (sociocultural adjustment) than do emigrants in the two other countries whose communities have lower levels of perceived ethnical vitality. Regression demonstrated that a higher level of perceived ethnic vitality and a lower level of perceived cultural distance were associated with more psychological adjustment. Moreover, emigrants who reported more perceived ethnic vitality interacted more frequently with both co-nationals and host nationals. Extraverted emigrants showed more psychological adjustment and interacted more frequently with host nationals. Acculturation orientations and coping were found to mediate antecedent conditions and outcomes. Attitudes towards host domain and seeking social support were positively associated with psychological adjustment and interactions with host nationals. Emigrants of the second generation were more oriented and better adjusted to the host country

CAD Model of a Gap in a Coplanar Waveguide

The partial capacitance approach and conformal mapping techniques are used to evaluate simple closed-form models for parallel and series capacitances of equivalent π-network of a symmetric gap in a CPW. Models are compared with experimental data and full wave analysis. They are useful for a wide range of CPW parameters and frequencies

On Temperature Dependence of Microstructure, Deformation Mechanisms and Tensile Properties in Austenitic Cr-Mn Steel with Ultrahigh Interstitial Content C + N = 1.9 Mass.%

The microstructure, deformation mechanisms, tensile properties and fracture micromechanisms of ultrahigh-interstitial austenitic Fe-22Cr-26Mn-1.3V-0.7C-1.2N (mass.%) steel were investigated in wide temperature interval. After conventional homogenization and solid-solution treatment, the steel possesses complex hardening which includes grain boundary, solid-solution and dispersion strengthening. In the temperature interval of −60 to +60 °C, steel demonstrates striking temperature dependence of a yield strength which could be enhanced by the increase in solid-solution treatment temperature. The variation in test temperature does not change the dominating deformation mechanism of the steel, dislocation slip and insufficiently influences tensile elongation and fracture micromechanisms. The insignificant increase in the fraction of brittle cleavage-like component on the fracture surfaces of the specimens in low-temperature deformation regime is promoted by increase in planarity of dislocation arrangement and the gaining activity of mechanical twinning. In high-temperature range (200–300 °C) of deformation, a negative strain-rate dependence, serrations on the stress-strain diagrams and improved strain-hardening associated with a dynamic strain aging phenomenon have been observed
