Background: Native Hawaiians (Hawaiian: kanaka `oiwi, kanaka maoli, and Hawai`i maoli) are the aboriginal Polynesian people of the Hawaiian Islands or their descendants. Native Hawaiians trace their ancestry back to the original Polynesian settlers of Hawaii. According to the U.S. Census Bureau report for 2000, there are 401,000 people who identified themselves as being "Native Hawaiian" alone or in combination with one or more other races or Pacific Islander groups. 141,000 people identified themselves as being "Native Hawaiian" alone.
Context: Another important outgrowth of the 1978 Hawai`i State Constitutional Convention was the establishment of the Office of Hawaiian Affairs, more popularly known as OHA. Delegates that included future Hawai`i political stars Benjamin J. Cayetano, John D. Waihee III, and Jeremy Harris enacted measures intended to address injustices toward native Hawaiians since the overthrow of the Kingdom of Hawai`i in 1893. OHA was established as a trust, administered with a mandate to better the conditions of both native Hawaiians and the Hawaiian community in general. OHA was given control over certain public lands, and continues to expand its land-holdings to this day (most recently with Waimea Valley, previously Waimea Falls Park).  Besides purchases since its inception, the lands initially given to OHA were originally crown lands of the Kingdom of Hawai`i used to pay the expenses of the monarchy (later held by the Provisional Government following the fall of the monarchy in 1893). Upon the declaration of the Republic of Hawai`i, they were officially designated as public lands. They were ceded to federal control with the establishment of the Territory of Hawai`i in 1898, and finally returned to the State of Hawai`i as public lands in 1959.  OHA is a semi-autonomous government body administered by a nine-member board of trustees, elected by the people of the State of Hawai`i through popular suffrage. Originally, trustees and the people eligible to vote for trustees were restricted to native Hawaiians. Rice v. Cayetano--suing the state to allow non-Hawaiians to sit on the board of trustees, and for non-Hawaiians to be allowed to vote in trustee elections--reached the United States Supreme Court, which ruled in favor of Rice on February 23, 2000, forcing OHA to open its elections to all residents of the State of Hawai`i, regardless of ethnicity.

Problem: Background: Irving Fisher (February 27, 1867 - April 29, 1947) was an American economist, statistician, inventor, and Progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman. Fisher made important contributions to utility theory and general equilibrium.
Context: Fisher was born in Saugerties, New York. His father was a teacher and a Congregational minister, who raised his son to believe he must be a useful member of society. Despite being raised in religious family, he later on became an atheist. As a child, he had remarkable mathematical ability and a flair for invention. A week after he was admitted to Yale College his father died, at age 53. Irving then supported his mother, brother, and himself, mainly by tutoring. He graduated first in his class with a B.A degree in 1888, having also been elected as a member of the Skull and Bones society.  In 1891, Fisher received the first Ph.D. in economics granted by Yale. His faculty advisors were the theoretical physicist Willard Gibbs and the sociologist William Graham Sumner. As a student, Fisher had shown particular talent and inclination for mathematics, but he found that economics offered greater scope for his ambition and social concerns. His thesis, published by Yale in 1892 as Mathematical Investigations in the Theory of Value and Prices, was a rigorous development of the theory of general equilibrium. When he began writing the thesis, Fisher had not been aware that Leon Walras and his continental European disciples had already covered similar ground. Nonetheless, Fisher's work was a very significant contribution and was immediately recognized and praised as first-rate by such European masters as Francis Edgeworth.  After graduating from Yale, Fisher studied in Berlin and Paris. From 1890 onward, he remained at Yale, first as a tutor, then after 1898 as a professor of political economy, and after 1935 as professor emeritus. He edited the Yale Review from 1896 to 1910 and was active in many learned societies, institutes, and welfare organizations. He was president of the American Economic Association in 1918. The American Mathematical Society selected him as its Gibbs Lecturer for 1929. A leading early proponent of econometrics, in 1930 he founded, with Ragnar Frisch and Charles F. Roos the Econometric Society, of which he was the first president.  Fisher was a prolific writer, producing journalism as well as technical books and articles, and addressing various social issues surrounding of the First World War, the prosperous 1920s and the depressed 1930s. He made several practical inventions, the most notable of which was an "index visible filing system" which he patented in 1913 and sold to Kardex Rand (later Remington Rand) in 1925. This, and his subsequent stock investments, made him a wealthy man until his personal finances were badly hit by the Crash of 1929.  Fisher was also an active social and health campaigner, as well as an advocate of vegetarianism, Prohibition, and eugenics. He died in New York City in 1947, at the age of 80.
