In this paper we discuss a project, still in progress, that moves away from a traditional lecture based educational pedagogy. We present a team taught approach to ethics teaching that embraces a progressive philosophy of education and is focused on the development of a discussion based learning community. We describe our primary pedagogical tools of case discussion and the development of student expert role assignments as a locus, and how they relate to the learning community, course content and course objectives. Finally, we provide our preliminary review of outcomes and emerging issues.  相似文献

Freeman (2006 ) suggested that auctioning immigration visas and redistributing the revenue to native residents in the host country would increase migration from low-income to high-income countries. The effect of the auctioning of immigration visas, in the Ricardian model from Findlay (1982 ), on the optimal level of immigration for the host country is considered. It is shown that auctioning immigration visas will lead to a positive level of immigration only if the initial wage difference between the host country and the source country is substantial. The cost of the immigration visa is more than half the earnings of the immigrant worker.  相似文献

No one would deny that sustainability is necessary for individual, business, and national survival. How this goal is to be accomplished is a matter of great debate. In this article I will show that the United States and other developed countries have a duty to create sustainable cities, even if that is against a notion of private property rights considered as an absolute. Through eminent domain and regulation, developed countries can fulfill their obligations to current and future generations. To do so, the governments must reject perfectly competitive free market capitalism and the absolute right to private property, and more fully adopt social welfare capitalism as their economic system. The result will be a sustainable society that balances democracy, individual rights and individual flourishing with the community’s flourishing.  相似文献

We examine how a project owner optimally selects a project operator and motivates him to deliver an essential noncontractible input (e.g., effort) when potential operators are privately informed about their limited wealth. Truthful revelation of wealth is induced by promising a higher probability of operation and, if necessary, a greater share of realized profit the larger the nonrefundable bond that a potential operator posts. The project owner benefits when total wealth is widely dispersed among potential operators. Under plausible conditions, limited knowledge of wealth is not constraining for the project owner.  相似文献
