In the US, following passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act , the Commodity Futures Trading Commission (CFTC) has proposed regulations aimed at limiting speculation in futures markets by instituting position limits. The CFTC offers three basic elements for their regulatory framework: "the size (or levels) of the limits themselves; the exemptions from the limits (for example, hedged positions) and; the policy on aggregating accounts for purposes of applying the limits."  The proposed position limits apply to 28 physical commodities traded in various exchanges across the US. 
Evolutionary anthropology came under fire in the fin de siècle from within anthropology itself. There were numerous contributing factors, including a new emphasis on the importance of anthropologists doing their own fieldwork rather than examining the reports of others. But in terms of cultural theory, the most important criticism was that of the American anthropologist Franz Boas (1858-1942). A German immigrant to the United States, he was influenced by German Romantic philosophy, including Herder’s insistence on cultural particularity. In 1896, Boas published an influential critique of Tylor’s science, “The Limitations of the Comparative Method of Anthropology,” in which he persuasively challenged the basic notions of psychic unity and independent invention upon which Victorian evolutionary anthropology rested. Boas had been actively contesting evolutionary orthodoxy since at least 1887, when he objected to the typological arrangement of ethnographic artifacts within American national museums, insisting that they should instead be displayed with other objects from their originating culture (Stocking, Shaping of American Anthropology 61-67). He argued throughout his work for cultural pluralism, for “cultures” in the plural, and with him began the final shift in anthropological thought from the traditional universalism to the new, particular theory of culture that characterized twentieth-century thought.
