Designing Fair Ranking Schemes
Items from a database are often ranked based on a combination of multiple
criteria. A user may have the flexibility to accept combinations that weigh
these criteria differently, within limits. On the other hand, this choice of
weights can greatly affect the fairness of the produced ranking. In this paper,
we develop a system that helps users choose criterion weights that lead to
greater fairness.
We consider ranking functions that compute the score of each item as a
weighted sum of (numeric) attribute values, and then sort items on their score.
Each ranking function can be expressed as a vector of weights, or as a point in
a multi-dimensional space. For a broad range of fairness criteria, we show how
to efficiently identify regions in this space that satisfy these criteria.
Using this identification method, our system is able to tell users whether
their proposed ranking function satisfies the desired fairness criteria and, if
it does not, to suggest the smallest modification that does. We develop
user-controllable approximation that and indexing techniques that are applied
during preprocessing, and support sub-second response times during the online
phase. Our extensive experiments on real datasets demonstrate that our methods
are able to find solutions that satisfy fairness criteria effectively and
efficiently

The Failure of American Socialism Reconsidered
Of all the questions that have bemused observers of political life in America, perhaps none has been as perplexing as that of why the United States, alone among the advanced industrial countries, never developed a truly mass-based socialist movement. Foreigners, in particular, have long been struck by the almost universal antipathy of Americans toward socialist ideas. Writing of the America of the 1830s, Tocqueville astutely observed that in no other country of the world is the love of property keener or more alert than in the United States, and nowhere else does the majority display less inclination toward doctrines which in any way threaten the way property is owned'. This attitude, Tocqueville argued, was uniquely suited to a society in which most of its members possessed property. Yet more than half a century later-and long after the formation of a massive wage-earning class-Engels, in a letter to Sorge, observed that the pervasive attachment to private property witnessed by Tocqueville persisted among American workers: 'It is remarkable,' he wrote, 'how firmly rooted are bourgeois prejudices even in the working class in such a young country.' Perhaps, suggested an exasperated Engels, the dogged resistance to socialist ideas among American proletarians reflected a pronounced theoretical backwardness: 'The Anglo-Saxon race-these damned Schleswig-Holsteiners, as Marx always called them-is slow-witted anyhow.
