This article provides a CGE analysis of the medium to long‐run impact of FDI inflows on poverty and income distribution in Bolivia. The simulation results suggest that FDI inflows enhance economic growth and reduce poverty. However, the income distribution typically becomes more unequal. In particular, FDI widens disparities between urban and rural areas. The Bolivian government may promote the growth‐enhancing and poverty‐alleviating effects by overcoming labour‐market segmentation and providing complementary public investment in infrastructure. But simulated policy reforms or alternative productivity scenarios are hardly effective in reducing the economic divide. 相似文献

Green facades—a view back and some visions 总被引:2,自引:1,他引:1
Manfred Köhler 《Urban Ecosystems》2008,11(4):423-436
Building facades are under permanent environmental influences, such as sun and acid rain, which age and can ultimately destroy
them. Living wall systems can protect facades and offer similar benefits to those gained from installing a green roof. A view
back in history shows that vegetated facades are not new technology but can offer multiple benefits as a component of current
urban design. In the 19th century, in many European and some North American cities, woody climbers were frequently used as
a cover for simple facades. In Central Europe in the 1980s a growing interest in environmental issues resulted in the vision
to bring nature into cities. In many German cities incentive programmes were developed, including some that supported tenant
initiatives for planting and maintaining climbers in their backyards and facades. Since the 1980s, research has been conducted
on issues such as the insulating effects of plants on facades, the ability of plants to mitigate dust, plants’ evaporative
cooling effects, and habitat creation for urban wildlife, including birds, spiders and beetles. The aim of this paper is to
review research activities on the green wall and facade technology with a focus on Germany. The potential of green facades
to improve urban microclimate and buildings’ ecological footprint is high, but they have not developed a widespread presence
outside of Germany because they are not as well known as green roofs and there is a lack of implementation guidelines and
incentive programs in other countries. 相似文献

Wade F. Horn 《Gender Issues》2006,23(4):22-35
In “Fatherhood, Cohabitation, and Marriage,” Wade F. Horn, Assistant Secretary for Children and Families at the Department
of Health and Human Services, summarizes the importance of fathers to child well-being. He explains that “fatherlessness is
a significant risk factor for poor developmental outcomes for children.” This connection has led some observers to view cohabitation
as a substitute or at least an alternative to marriage. Horn argues, however, that marriage is the best option for children
and that cohabitation is a weak family structure compared with marriage. Children in households with married parents do better
on almost every measure of child well-being, even after controlling for income. 相似文献
