This paper attempts to analyze the pure consumption of exhaustible resource under hy- perbolic time preference, and to discuss the optimal depletion rate and the effect of the protection of the exhaustible resource under different commitment abilities. The results of model show that the case of the hyperbolic discount with the full commitment of the govemment is equivalent to the case of constant discount of the social planner problem. In that case, the optimal depletion rate and the initial consumption of exhaustible resource are the slowest. On the contrary, they are the highest and the myopic behaviors lead to excessive consumption of exhaustible resources inevitably without commitment. Otherwise, in the case of partial commit- ment, the results are between the cases of full commitment and of no commitment. Therefore, with the hyperbolic time preference, the optimal depletion rate of resource depends on the commitment ability. Higher commitment ability leads to lower effective rate of time preference, and consequently, lower depletion rate and lower initial depletion value. The improvement of commitment ability can decrease the impatience and myopia behaviors, and contribute to the protection of the exhaustible resources.展开更多

This urban slum is plagued by unsanitary conditions, such as high density, dust, mud, squalor, hazards, litter, and smell. As a result of these deplorable conditions, Umande Trust, a local non-governmental organization （NGO）, has developed a new educational initiative using biotechnology to turn human waste into gas for cooking. This initiative supports Freire＇s （2000） theory pedagogy of the oppressed, which will serve as the theoretical framework, in which the people who have been oppressed and/or have had to endure the horrible conditions in which they live play an active role in their development to regain their humanity. Jacobson （2004） raised a critical question that will be the focal point of this study regarding development： ＂Who is better suited to help Africa determine her future＂ （p. 75）. Using a qualitative case study design, the answer to this question will be answered in terms of Kibera specifically and its use of bio-technology as a sustainable development initiative. This study will also assess the use of communication in this approach.展开更多

The employment post cannot satisfy the need of the talented person＇s production. The employing situation is getting worse gradually. How to find the realistic reasons and seek out a feasible way, and how to get rid of the current employment difficulties will become one of our major tasks. Through the investigation and analysis, we find out the mismatch on one-sided enrollment expansion of higher education with the economic system and the model of talent training. The prominent contradictions of the professional settings in universities with the marketing demands is the main reason of difficult employment.

Solving the employment problem is the foundation of stable development of social economy. Through a lot of investigation and study, we have carried on the thorough analysis to solve the problems Thinking that we seek truth only from facts, especially knowing reality and admitting the reality, we could find the reasonable solution to resolve a series of problems in the process of popularization of higher education, and to promote the scientific development and progress of higher education and social economy展开更多
