In 1899 the age of sexual consent in some American jurisdictions was 9 years. It has ranged from 7 to 21 years and at present the range is from 11 to 18 years. The age selected seems to be an arbitrary matter, the product of legislative compromise. The age of sexual consent should not be so early that little protection is provided for a child. Conversely, it should not be so late that a man can be held for statutory rape when the "victim" is fully capable of informed consent and readily acquiesced to a proposal or even invited a sexual relationship.  相似文献

Fires that occur either while aircraft are in flight or as a consequence of a crash remain life-threatening possibilities despite progress in technology and adoption of safety precautions. This article details some of the likely causes of aircraft fires, the resulting dangers in the immediate environment, prospects for survival, and recommends additional measures that may help avoid future accidents.  相似文献

In recent years, numerous cities in the U.S. have enacted taxes on beverages to promote health and raise revenue. This paper examines the impact of Philadelphia's beverage tax, enacted in 2017, on the prices and availability of both taxed and untaxed beverages. Using original data we collected in late 2016 and again one year later, we estimate difference-in-differences regressions of the change over time in beverage prices and availability in stores in Philadelphia relative to stores in nearby counties. We find that, on average, distributors and retailers fully passed through the tax to consumers. Pass-through is higher for individual servings than for larger sizes. There is also heterogeneity in the pass-through rate among stores; it is greater among stores that are in higher-poverty neighborhoods, located farther from untaxed stores outside Philadelphia, and that are independent as opposed to part of national chains. We also find that the tax reduced the availability of taxed beverages and increased the availability of untaxed beverages, particularly bottled water, in Philadelphia stores.  相似文献
