But at present, the graduates that the traditional teaching systems of the independent colleges which cultivate the application-oriented specialists cannot completely meet the requirement of the society. Therefore, colleges and universities should take the professional English ability as the core, and make the major reform from the teaching concepts of the college English teaching, the teaching models, and the teaching evaluation and so on, and establish the new system of college English teaching.展开更多

We found that although the increased rate of population urbanization did not produce a significant difference between "rural migrants" and "city people" in terms of income, migrants fare considerably worse than city people with regard to social security, cultural life, psychological acceptance and status identification. This kind of inequality transforms the original urban/rural dual structure into a new dichotomy that divides urban dwellers into the migrant population and residents with urban household registration, thereby impeding social integration. This finding will help us understand the causes of the social barriers in current urbanization and may provide theoretical and empirical reference material for "new-type urbanization," particularly as it relates to the transformation of the rural migrant population into urban citizens.展开更多

In the lower Mississippi Valley(LMV) the Poverty Point culture defined this period of socio-political elaboration. However, following a significant period of climate change that led to exceptional flooding and a major reorganization of the course of the Mississippi River, this culture collapsed beginning ca. 3300–3200 cal yr BP and the LMV was abandoned for the subsequent 500 years. In this study, we use data from the Jaketown site in the Yazoo Basin of west-central Mississippi to refine the chronology of the climate event that caused the collapse of the Poverty Point culture. A large flood buried Poverty Point-era occupation deposits at Jaketown around 3310 cal yr BP. Lateral migration of the Mississippi River during flooding led to inundation of the Yazoo Basin and re-occupation of ancient river courses. A coarse sand stratum topped by a more than a meter-thick fining upward sediment package marks a crevasse deposit caused by a rupture of the natural levee at Jaketown. This levee breach was part of a larger pattern of erratic flooding throughout the LMV and is associated with major landscape evolution and the abandonment of Poverty Point sites within the valley. Early Woodland peoples re-colonized the crevasse surface after ca. 2780 cal yr BP. Following this event, the Jaketown site and the eastern Yazoo Basin witnessed a period of landscape stability that lasts to this day. These archaeological data demonstrate how climate change and natural disasters can lead to socio-political dissolution and reorganization even in relatively small-scale hunter-gatherer populations.展开更多

The increasing population, urbanization, land-use changes, and the climate significantly affect coupled natural and human systems and threaten environments and socio-ecological land systems. The degradation of drylands poses a severe and widespread threat to the lives of millions of people, especially in developing countries and in the global environment. This review assesses published literature on dryland socio-ecological systems to reveal current research trends and changes in research themes over time and introduces basic theories and advances in dryland socio-ecological system frameworks, resilience measurement, and regime shifts. Developing a more general but adaptable framework and a more practical strategy for long-term coordination and partnership and attaining specific insights into ecological services should receive more attention and be strengthened in future studies on drylands sustainability.展开更多

By tracing China's reform experience and comparing it with the mainstream reform strategies, the paper argues that, first, Chin's reform strategy is fundamentally different from the conventional reform strategies; second, China's success to a large extent is the result of Chinese leaders' decision making and careful management over reform process rather than of simply market force. Finally, the paper suggests that the active role the Chinese Communist Party plays in economic reform grants its legitimacy, thus enabling it to enjoy political stability under long term rapid economic and social transition.展开更多
