Realizing the benefits of globalization depends on a host of realistic conditions including technology and infrastructure, geopolitical pattern and the structure of market power, and international institutional arrangements, i.e., the global governance structure, among others. In this new era of economic globalization, international competition boils down to the ＂good governance＂ of countries rather than the use of force and hegemonism. Most importantly, a country must promote the vibrancy of innovation in order to stay competitive and creative. In this sense, China＇s position in the new era of economic globalization hinges upon its transition from being the ＂leader of world economic growth＂ to being a future ＂leader of good governance and vibrancy. ＂ Interests of various economies become interlocked, intertwined and overlap. Despite the inevitability of conflicts and frictions, more inclusive and balanced global development serves the interests of most nations. For great powers with extended boundaries of interests across the world, the maintenance of the new balance of power in economic globalization is consistent with their respective national interests. Hence, in the new era of economic globalization characterized by the inevitability of intricate interests and inevitable conflicts, the world is likely to be more peaceful, competitive and inclusive than any previous age of economic globalization.展开更多

And the formation mechanism of the scattering resonance states of this reaction was well interpreted with the partial potential energy surface. The scattering resonance states of this reaction should belong to Feshbach resonance because of the coupling of the vibrational mode and the translational mode. With the one-dimensional square potential well model, the resonance width and lifetime of the I＋HI（v=0）→IH（v＇=0）＋I state-to-state reaction were calculated, which preferably explained the high-resolved threshold photodetachment spectroscopy of the IHI- anion performed by Neumark et al..展开更多

For instance, it is a source of employment, cultural preservation, presentation, and projection. It also serves therapeutic functions and as social control mechanism in a society. It is a mirror of life, reflecting and highlighting the moral codes and the ills of society and castigating social evil and its doers. Beyond all of these, the theatre could also serve as an agent of civilization, community mobilisation, and youth development and emancipation. This paper discusses how the potentials of the youth in a country such as Nigeria, could be harnessed and deployed for the purposes of national orientation, development, and integration, using culture, drama, and theatre as the defining tools for this evolvement.展开更多
