This paper obtains an evolving pattern of goods market integration in Russia, considering the period of economic upturn, since the second half of 2000 through the end of 2007. In an integrated market, the price of a tradable good at any location is determined by the national market, not local demand. Based on this, the strength of dependence of local prices on local demands is used to detect an...

This paper adopts the industrial capabilities argument and the concept of revealed comparative advantage as the basis for evaluating the competitiveness of the UK creative industries in sustaining export growth. The empirical results have revealed a heterogeneous nature of the economic linkages and comparative advantage positions within the UK creative sector. There is also evidence to support ...

Spatial econometrics has been an ongoing research …eld. Recently, it has been extended to the panel data settings. The spatial panel data can allow cross sectional dependence as well as state dependence, and it can also enable researchers to control for unknown heteorgeneity. This paper reports some recent developments in the econometric speci…cation and estimation on spatial panel data models....

This paper investigates spatial panel data models with spatially and serially correlated disturbances. We …rst discuss the short panels and consider their estimation by both …xed e¤ects and random e¤ects speci…cations. With a between equation properly de…ned, the di¤erence of the random vs. …xed e¤ects models can be highlighted. We show that the random e¤ects estimate is a pooling of the within...

Puberty is a remarkable developmental process with the activation of the hypothalamic–pituitary–gonadal axis culminating in reproductive capacity. It is accompanied by cognitive, psychological, emotional, and sociocultural changes. There is wide variation in the timing of pubertal onset, and this process is affected by genetic and environmental influences. Disrupted puberty (delayed or absent) ...

A genetic map containing 103 microsatellite loci and 200 F2 plants derived from the cross R15 × Ye478 were used for mapping of quantitative trait loci (QTL) in maize (Zea mays L.). QTLs were characterized in a population of 200 F2:4 lines, derived from selfing the F2 plants, and were evaluated with two replications in two environments. QTL mapping analysis of plant height was performed by using...

The temperature and pressure dependence of the addition reaction of ethyl methyl ketone (EMK) with HȮ2 radical has been calculated using the master equation method employing conventional transition state theory estimates for the microcanonical rate coefficients in the temperature range of 600–1600 K. Geometries, frequencies, and hindrance potentials were obtained at the B3LYP/6-311G(d,p) level ...
