Parental influences on the development of adolescent autonomy and identity

Two studies were undertaken to examine parental influences on autonomy and identity development. In Study 1, 262 adolescents in seventh and eleventh grades were given Kurtines's autonomy measure, Simmons's identity measure, and Elder's questions regarding the adolescents' perceptions of their parents' autocratic, democratic, or permissive parenting styles. Study 2 was a replication with 168 subjects. Across both studies it was found that sex-role socialization is more influential for automony development than is either level of parental power or age. Both age and father's use of democracy were the most influential variables on identity development.Received Ph.D. from the University of Minnesota.

The dynamic evolution of the Greek regional net fixed capital time series

This paper investigates the impact of different depreciation methods on the dynamic characteristics of the Greek regional net fixed capital series. Using annual data over the period from 1974 to 2006, Karpetis and Zikos (Int J Econ Res 11(2):333–354, 2014) constructed the series of nominal net fixed capital in the case of the thirteen administrative regions of Greece, applying four different depreciation methods of capital. In the context of the present analysis, these series were initially deflated, using the country’s G.D.P. deflator (2005 = 100), and subsequently were exploited to investigate their dynamic characteristics through estimation of the best fitted ARIMA(p,d,q) models and determination of the roots of the characteristic polynomials. The statistical findings reveal, firstly, the impact of the employed depreciation methods of capital on the evolutionary pattern (monotonic or sinusoidal) of the series and secondly, the slow convergence of the Greek regional net fixed capital towards its long-run equilibrium value.
