the data were collected from 1992 to 2009 in burri, white boni and black boni sheep maintained at the regional research station in the central highlands of yemen. data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. the least square means for body weights (bw) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

According to their symmetry, flowers are classified as radially symmetrical or bilaterally symmetrical. Bilateral symmetry, which is thought to have evolved from radial symmetry, results from establishment of asymmetry relative to a dorsoventral axis of flowers. Here we consider developmental genetic mechanisms underlying the generation of this asymmetry and how they relate to controls of petal...

Shuming Bao University of Michigan [email protected] IIntroduction Although spatial phenomena have been extensively studied in various research fields, such as economic geography (e.g., convergence in per capita income growth rates, inter-regional and intersectorial flows of labor and capital, and regional resource endowments), environmental sciences (e.g., dispersion of air-borne pollutants, soil...

We evaluated whether growth rates of six fish species correlated with PCB concentrations in a moderately-to-heavily polluted freshwater ecosystem. Using a large dataset (n = 984 individuals), and after accounting for growth effects related to fish age, habitat, sex, and lipids, growth correlated significantly, but positively with lipid-corrected PCB concentrations for 4 of 6 species. Remaining ...

Regional knowledge capital has become one of the key factors of economic development of a nation and region, and enhanced the regional competitiveness greatly. In this paper, firstly, the connotation of the regional knowledge capital is introduced, and then the synergy model of the system between knowledge capital and regional economic growth is constructed. Secondly, the synergy of the model i...

The paper is based on recent theoretical writings in growth economics that emphasise the effects of both own research and development efforts and of interregional technology spillovers on regions’ productivity. It proposes robust e...

This annotated bibliography gives an overview of the theoretical literature on regional economic growth and examines its conceptual foundations, major competing paradigms, and recent developments. The overview concludes with a discussion of the policy implications suggested by this body of theory. Throughout the review, three themes are emphasized: (1) the theoretical predictions regarding the ...
