Political choice and the child labor statute of 1938: Public interest or interest group legislation?
Federal regulation of child labor (unlike that passed in early nineteenth century England) did not materialize until the New Deal of the 1930s. The present paper examines, using anecdotal and empirical evidence, the motives underlying the passage of depression-based child labor legislation embodied in the Senate vote on the Fair Labor Standards Act (FLSA). Our study, which utilizes both dichotomous and trichotomous probit models of the vote, finds evidence that there were critical and dominantprivate as opposed to public interests behind the restrictions that the FLSA placed on child labor and the exemptions that it established. 相似文献

Tax Increment Financing (TIP) uses the increase in taxes resulting from an area's redevelopment to help subsidize the costs of redevelopment. The paper focuses on the mechanisms and problems of using real property tax increments under Illinois law. Two distinct methods of calculating tax increments, the "aggregate" and "parcel" methods, are examined. A briefcase study is provided. 相似文献

The assessment of dangerousness is not a diagnosis, but rather a clinical impression based on the individual's past history
of violence and many other factors. With regard to the mental state, it has been noted that “the essence of dangerousness
appears to be a paucity of concern for others'” (Roth, 1974). As a subjective opinion, predicting violence and future dangerousness
bears the weight of much scrutiny and due diligence. Threat assessment evaluations have inherent social and legal ramifications,
and the responsibility must be accepted with the knowledge that accuracy may not always be achieved. This paper discusses
the various aspects of predicting future violence and dangerousness and the caveats that come with such tasks. 相似文献

Differential extraction is an efficient method to separate sperm cells from epithelial cells. A manual Chelex®-100 based method is used at the Swedish National Laboratory of Forensic Science, SKL. The Differex™ System (Promega) uses a Proteinase K digestion of epithelial cells followed by centrifugation and phase separation. The sperm- and epithelial fractions are further purified with DNA IQ™ System (Promega) or with phenol/chloroform. The Differex™ System in combination with DNA IQ™ System were evaluated and compared to the Chelex®-100 method used routinely. After modifications, the Differex™ System gave comparable results to the Chelex®-100 method. The modifications included additional Proteinase K and DTT, longer incubation time and additional steps when removing the solid support from the Digestion Solution. In the Chelex®-100 based method microscopic examination is done on the sperm pellet in a total volume of 50 μl. It was not possible to do a microscopic examination in less than 100 μl using the Differex™ System. Additionally the sperms were in clusters of epithelial cell debris. Microscopic examination is an important part of the differential extraction at SKL. Therefore, the Differex™ System will not be implemented at our laboratory. 相似文献

Why a combatant command for Africa? I argue that AFRICOM was formed to implement the U.S. national security strategy that seeks to strengthen states and eliminate ungoverned space, as well as establish relationships with African states that offer a means to greater state stability and foster economic development. In so doing, it counters global jihadist by denying them haven among weak governments or in ungoverned areas. It protects U.S. interests in resources by helping governments become more stable. And it competes with the Chinese approach that could worsen the status quo of ineffective states and ungoverned space. Indeed, the U.S. approach of increasing state effectiveness makes African countries less susceptible to the problems that may arise from the Chinese approach and so serves China's interests in access to natural resources. 相似文献
