This paper analyzes voting behavior for President, Senate, andHouse at the state level for the period 1914–80. The majorfinding of this study is that since World War II, there hasbeen a pronounced trend toward "particularization" in votingfor federal offices. This trend consists of more than the erosionof party attachments among the electorate; it also includesthe dissolution of other traditional electoral ties such aspresidential coattails, the midterm congressional swing, andincumbency. As a result of this trend, the vote in federal electionsis largely determined by factors which are unique to the specificsetting in which each election occurs and by the ability ofcandidates to convert these factors to their political advantagethrough mass media campaigns. 相似文献

An important issue being discussed for Chilean pine plantation policies is the application of environmental protection measures when managing its timber areas. Typical measures, already in place in more developed countries, include imposing riparian strips and protecting fragile soils from the use of heavy machinery. While environmental protection measures have been considered vital for decades, so far there has been almost no attempt to quantify both the benefits and costs of these measures. This paper attempts to measure the costs associated with the main measures which can help both the forestry firms and the government evaluate the cost impact of the new environmental protection regulations being studied. The analysis for different environmental scenarios is carried out by modifying a mixed integer LP, currently used for tactical planning by one forestry firm. 相似文献
