The purpose of this article is to discuss some basic methods for optimally allocating federal money to cities. Optimally allocating in this context means using the quantitative methods of operations research, management science, and related fields in order to allocate federal money to cities in such a way as to (1) maximize benefits subject to a given budget, (2) minimize costs subject to a minimum satisfaction level, or (3) maximize benefits minus costs. The basic methods include (1) allocating by marginal rates of return, which partly relies or statistical regression analysis; and (2) allocating by part/whole percentages, which partly relies on ideas associated with multiattribute utility theory. The basic methods will be illustrated with the example of allocating anticrime dollars to cities, although one could easily reason by analogy to allocation in any subject matter area. 相似文献

A controlled laboratory experiment was conducted in order to investigate the effect of the method of burial (i.e. the presence of coffin and clothing) on the formation of adipocere. This study follows previous studies by the authors who have investigated the effect of physical conditions on the formation of adipocere present in a controlled burial environment. The study utilises infrared spectroscopy to provide a preliminary lipid profile of the remains following a 12 month decomposition period. Inductively coupled plasma-mass spectrometry was employed as a technique for determining the salts of fatty acids present in adipocere. Gas chromatography-mass spectrometry (GC-MS) was used as the confirmatory test for the identification and determination of the chemical composition of adipocere which formed in the controlled burial environments. The results suggest that coffins will retard the rate at which adipocere forms but that clothing enhances its formation. The results concur with previous observations on adipocere formation in burial environments. 相似文献

This study examined effects of clothing cues on children's identification accuracy from lineups. Four- to 14-year-olds (n = 228) saw 12 video clips of individuals, each wearing a distinctly colored shirt. After watching each clip children were presented with a target-present or target-absent photo lineup. Three clothing conditions were included. In 2 conditions all lineup members wore the same colored shirt; in the third, biased condition, the shirt color of only one individual matched that seen in the preceding clip (the target in target-present trials and the replacement in target-absent trials). Correct identifications of the target in target-present trials were most frequent in the biased condition, whereas in target-absent trials the biased condition led to more false identifications of the target replacement. Older children were more accurate than younger children, both in choosing the target from target-present lineups and rejecting target-absent lineups. These findings suggest that a simple clothing cue such as shirt color can have a significant impact on children's lineup identification accuracy. 相似文献

The analysis of fatty acids from common vegetable oils was investigated for application to forensic casework. A base-catalyzed transesterification of the fatty acids to fatty acid methyl esters using tetramethylammonium hydroxide was simple, rapid, straightforward and inexpensive. Canola, corn, olive, peanut, safflower, soybean and sunflower oils were able to be classified based on their fatty acid methyl ester profiles. Using gas chromatography-mass spectrometry, the detection limits for canola, corn, olive, peanut and safflower oils were determined to be 0.4 mg/mL or less and 0.2 mg/mL or less for soybean and sunflower oils. 相似文献

The objective of this paper is to introduce managers of R&D operations to tax issues that must be considered when technology is transferred across international boundaries within the same company. The tax implications are often misunderstood or even overlooked in the technology transfer process. The paper explains how countries seek to tax their fair share of the income earned inside their borders. Since the amount of income earned depends on the price for technology paid by one part of a company to another, this transfer price is of keen interest to the tax authorities. To preserve their tax bases, therefore, countries establish rules to regulate the international transfer of goods and services, including technology, between related parties. This paper provides an overview of the economic principles underlying these rules, and illustrates their application with a series of examples. 相似文献
