This paper develops a multisector residential energy policy model. This model hypothesizes that household energy behavior is affected by conditions in the housing, the mortgage finance, and the energy markets. The relationships encompassed by the model are specified with 32 single and simultaneous equations and tested with quarterly data drawn from behavior in Delaware. After the testing and evaluation of the model for its statistical performance, thereafter, three energy policies are simulated a 5 percent residential energy consumption tax, a set of conventional insulation requirements for all new housing, and a passive solar-installation requirement for all new housing. These policy choices are evaluated in terms of their impact on energy consumption, prices, demand and size of different types of housing permits, and mortgage financing. Finally, the economic and social implications of these policy impacts are discussed. 相似文献

Early Chinese texts speak of the Han state conquering the kingdom of Dian in southwest China in 109 B.C. The limited historical record is complemented by archaeolgical discoveries pointing to the presence in Yunnan province of a complex Bronze Age society whose association with the historical Dian has been generally accepted. Historiographic and nonprocessual in nature, archaeology in Yunnan has yet to generate the data needed for a deeper understanding of Dian social structure and change. Whatever its shortcomings, however, Dian archaeology plays a consistent and important role within a system of thought which gives preeminence to the historical record. 相似文献

Destination planning raises questions relative to spatial organization within the destination and to the spatial extent of the gains generated by attractions. Thus, it is important to increase understanding and knowledge of the mechanisms by which attractions generate tourism development. The aim of this study is to analyze how tourist attractions influence tourism development within destination and what the spatial extent of this influence is. It is argued that both the appeal of tourist attractions and their spatial characteristics are determining factors. Thus, distinguishing local, spread, and diffuse attractions is essential and specific indicators were created to that purpose. Using count data models, an econometric analysis was conducted in order to test the effect of attractions on the number of hotel rooms in 2015 on the one hand, and on the number of employees in the tourism sector in 2014 on the other, in French municipalities. The study brings several original results. First, as in the case of green areas, some attractions may trigger the emergence of tourism development but may also have a depressive effect on the level of tourism development when they exceed a certain threshold. Second, the influence of sport and leisure facilities is more limited in space than for ski slopes, beaches and tourist sites, which confirms that the appeal of attractions determine the spatial extent of tourism development. Third, beyond a distance threshold, some attractions can generate negative spatial spillovers and have a depressive effect on tourism development. 相似文献

This article shares the first-time geographic information system (GIS) experiences of two advanced placement human geography classes. The teacher had participated in a summer GIS workshop and then brought those skills into her classroom for the students' benefit. Eighteen students shared their experiences researching their family history, working to map the migration of their genealogy to the United States, and presenting their findings to their classmates. Researchers were on hand to observe presentations and collected survey data from the students. Overall it was a very successful educational experience in which students utilized a “new” technology in the context of their own lives. 相似文献
