Are two- or four-year colleges more efficient at increasing the educational attainment of young adults? I use state variation in two- and four-year college systems to address this question at the state level. I find that the composition and cost of higher education in a state affect the enrollment decisions of individuals in that state. Further, attending a two-year rather than a four-year college may lower the educational attainment of some students, but more students will benefit from the community college alternative. It also most likely costs the state more to educate a student in a four-year rather than a two-year college. As a result, community colleges provide a potentially efficient way to increase access to higher education as well as increase the overall educational attainment of a state's residents. 相似文献

Reliability of a two-dimensional footprint measurement approach 总被引:1,自引:0,他引:1
Although footprint evidence can be taken from the scene of a crime, the science underpinning such measurement in forensic science has not been fully explored.A literature search revealed various measuring approaches, all of which demonstrated either little or no measurement rigour in terms of reliability. The aim of this study was to apply a robust measurement approach for testing the reliability of two-dimensional footprint impressions.Three dynamic and three static footprints were taken from the right foot of thirty female and thirty one male volunteers using the ‘Inkless Shoeprint Kit’. The images were digitised. Lengths, widths and angles were measured using a selection of currently employed methods.An investigation of the reliability of the chosen measuring method suggested high intra-rater agreement: for example, the length measurement suggested an intraclass correlation coefficient (ICC) 0.99, 95% Confidence Interval (CI) ? 0.28 to 0.01, standard error of measurement (SEM) 0.07, Limits of Agreement (LOA) ? 0.91 to 0.65.Inter-rater reliability between three operators was also high: SEM ranged from 0.05 mm to 0.07 mm, ICC 0.99.Our study has established a reliable two-dimensional measuring technique that could be used for footprint comparison in further research. 相似文献

One hundred and twenty eight cases of shooting fatalities were investigated during an 11-year period. Of these 57% were homicidal shootings with 34% suicidal in nature. Only two suicidal fatalities were female. Analysis of the sites of entrance wounds confirmed the 'sites of election' in suicidal shootings, whilst homicidal wounds showed a much wider distribution. Multiple entrance wounds were seen in 42% of homicidal shootings. Injuries to hands were seen in 7 homicidal fatalities. 相似文献

In recent years capital spending in the health care industry has escalated tremendously, and most forecasters agree that needs will increase at an even faster rate throughout the 1990s. As a result of this trend, there is a dire need to develop effective and equitable controls on capital spending in health care. One of the capital payment options under consideration is the establishment of a lid on capital expenditures and the concomitant allocation of capital to health care providers whose applications are the most meritorious. The purpose of this article is to present some ideas and methods for the development of a relative need system to accompany a capital expenditure limit and to supplement and expand the absolute need determinations of the typical CON process. 相似文献
