Hyperbolic subdiffusive impedance

We use the hyperbolic subdiffusion equation with fractional time derivatives (the generalized Cattaneo equation) to study the transport process of electrolytes in media where subdiffusion occurs. In this model the flux is delayed in a non-zero time with respect to the concentration gradient. In particular, we obtain the formula of electrochemical subdiffusive impedance of a spatially limited sample in the limit of large and of small pulsation of the electric field. The boundary condition at the external wall of the sample are taken in the general form as a linear combination of subdiffusive flux and concentration of the transported particles. We also discuss the influence of the equation parameters (the subdiffusion parameter and the delay time) on the Nyquist impedance plots.Comment: 10 pages, 5 figure

Psychopathology in adolescents from seven countries: What role does controlling identity development and family relationships play?

This study analyzed the unique effects of gender and culture on psychopathology in adolescents from seven countries, after controlling for factors that might have contributed to variations in psychopathology. In a sample of 2259 adolescents (M = 15 years; 54 % female) from France, Germany, Turkey, Greece, Peru, Pakistan, and Poland, we assessed identity development, maternal parenting (support, psychological control, anxious rearing), and psychopathology (internalizing, externalizing). Using an analysis of covariance (ANCOVA), we analyzed country, sex, age, and the interaction country x sex as independent variables, while controlling for maternal rearing dimensions and identity development as covariates. This resulted in similar findings for internalizing and externalizing symptoms: Identity rumination and maternal rearing (support, psychological control, anxious rearing) proved to be significant covariates. Further, country, sex, age, and the interaction country x sex were significant. These analyses result in a clearer picture of culture- and gender-specific effects on psychopathology, which is helpful in designing interventions. © 2018 Hogref

Emerging Adults’ Psychopathology in Seven Countries: The Impact of Identity-Related Risk Factors

The impact of identity-related risk factors on psychopathology was analyzed in 2,113 emerging adults (M = 22.0 years; 66% female) from France, Germany, Turkey, Greece, Peru, Pakistan, and Poland. Identity stress, coping with identity stress, maternal parenting (support, psychological control, and anxious rearing), and psychopathology (internalizing, externalizing, and total symptomatology) were assessed. After partialing out the influence of stress, coping, and perceived maternal behavior, country did no longer exert a significant effect on symptom scores. The effect for gender remained, as did an interaction between country and gender. Rather unexpected, on average, males reported higher internalizing symptomatology scores than females. Potential causes for the higher scores of males are therefore discussed. Partialing out covariates resulted in a clearer picture of country-specific and gender-dependent effects on psychopathology, which is helpful in designing interventions. © 2018 Society for the Study of Emerging Adulthood and SAGE Publishing

Psychopathology in emerging adults in seven countries: Impact of identity-related risk factors [Psychopathologie bei jungen Erwachsenen aus sieben Ländern: Einfluss identitätsbezogener Risikofaktoren]

The study examined the influence of culture and gender on psychopathology after controlling for identity-related risk factors. A total of 2113 young adults from 7 countries (France, Germany, Poland, Greece, Turkey, Peru and Pakistan) answered a questionnaire on symptom burden, identity development and family relationships. After controlling for identity-related risk factors (e. g. identity development, maternal upbringing styles), the strong country effect on symptom burden disappeared. While there were practically no gender effects in western countries, in countries such as Peru, Pakistan, Poland and Turkey men reported significantly higher symptom burdens than women. In accordance with DSM-5, a weakening of the cultural effect and a certain universality of mental symptoms was found with a clear interaction between country × and gender. New is the greater vulnerability of men in some countries. © 2018, Springer Medizin Verlag GmbH, ein Teil von Springer Nature
