Schools that participate in the National School Lunch Program receive a portion of their federal funding as commodity foods rather than cash payments. This research compared the product costs and estimated total procurement costs of commodity and commercial foods from the school district perspective using data from 579 Minnesota ordering sites in school year (SY) 2008–2009. Though comparison of product prices indicates that commercial foods were an average of 17 percent more expensive than equivalent commodity foods, once full estimated procurement costs were included, the commercial products became 9 percent less expensive per food case than commodity products. Base case results were sensitive to the cost of risk to hold inventory. When this input was tested at zero, the estimated cost to procure commercial foods was 2 percent higher per case than commodity foods, though total commercial procurement costs remained less than commodity costs by 3 percent. It is estimated that Minnesota schools collectively spent an additional $1.7 to $3.7 million to procure USDA commodity foods in SY 2008–2009. © 2009 by the Association for Public Policy Analysis and Management.  相似文献

The first synthesis of the 2,3-isomers of MDPV, butylone and methylone is reported. The isomers were characterised by (1)H and (13)C NMR spectroscopy and compared to the corresponding 3,4-isomers. A GC method is described which separates the 3,4- and the 2,3-isomers from each other. IR spectra of the 2,3-isomers are also compared with the corresponding 3,4-isomers. Two seized drug samples were analysed by GCMS and the samples were found to contain the 3,4-isomers.  相似文献

The paper applies the concepts of the horizon problem, agency costs, monitoring, and special interest incentives to trustee management of public schools and higher education. We examine whether South Carolina's 1984 Education Improvement Act, a major restructuring of educational organization and spending in South Carolina, is related to the ratio of pupils in private versus public schools. We employ 30 years of county level data in South Carolina, and we uncover several things. There is no statistically credible relation between public school expenditures per pupil and the private school/public school enrollment ratio. However, we do find that the directed changes in rules, organizational structure, and incentives mandated by the 1984 Educational Improvement Act are associated with a reduction in the relative number of children attending private school. We interpret this to mean that the features of the law requiring better accountability and the like were perceived by parents to make for better education while the increased money spent was only a transfer to teachers or some other groups; we find that organization matters more than money.  相似文献

A certain number of single‐vehicle crashes into stationary roadside objects such as trees are thought to be occult suicides. However, is it possible that some cases of multiple deaths within a family in similar crashes are due to unrecognized familial murder‐suicides? A 39‐year‐old woman and her 11‐year‐old daughter are reported who died of injuries following a vehicle impact with a tree. Unusual behavior of the mother leading up to the crash, and assessment at the scene, raised the possibility of this being a nonaccidental event. However, difficulties in retrospectively determining the intent of a driver in a vehicle crash, and the nonrecording of, or lack of separate coding for murder‐suicides on registers, make determination of the incidence of these types of events extremely difficult. It may be that this is a subcategory of murder‐suicide that is underdiagnosed and so is not being registered on central motor vehicle crash databases.  相似文献
