How green was my valley? Urban history in Latin America

The history of Latin America has been dominated by ideas of order and progress. Unfortunately those ideas have not always been of regional origin. In the colonial era the conquest and conversion of the native peoples was seen as progress by the Europeans. The imposition of order was aided greatly by urbanization sometimes symbolically on the ruins of Indian cities such as at Cuzco and Mexico City. Cities became the point of cultural and economic articulation between the barbaric hinterland and the civilization of Europe. Freedom from the Spanish yoke gained in the Independence wars was similarly seen as progress, at least by the ultimately victorious creole ‘patriots’. It was here, however, that notions of national identity, modernization and economic success became intertwined to produce the conflicts which still inflame the region today. The paramount question has remained: whose order and concept of progress should be imposed

Truth is mighty & will eventually prevail Political Correctness, Neo-Confederates, and Robert E. Lee

Jefferson Davis sent Robert E. Lee an unusual note after the battle of Gettysburg. The dispatch did not contain any presidential recommendations or requests, only a clipped article from the Charleston Mercury criticizing Lee and his subordinates for failure in Pennsylvania. Why Davis sent this article is impossible to say, and Lee apparently was not interested in the president’s motivations. The General dismissed newspaper criticism of himself as “harmless,” but the Mercury’s condemnation of the army disturbed him. He considered the charges harmful to the cause, for his officers and soldiers were beyond reproach. Defeat, Lee insisted, was his responsibility alone. “No blame can be attached to the army for its failure to accomplish what was projected by me,” he wrote, “nor should it be censured for the unreasonable expectations of the public. I am alone to blame, in perhaps expecting too much of its prowess & valour. [excerpt

The Problem of Post-Truth. Rethinking the Relationship between Truth and Politics

‘Post-truth’ is a failed concept, both epistemically and politically because its simplification of the relationship between truth and politics cripples our understanding and encourages authoritarianism. This makes the diagnosis of our ‘post-truth era’ as dangerous to democratic politics as relativism with its premature disregard for truth. In order to take the step beyond relativism and ‘post-truth’, we must conceptualise the relationship between truth and politics differently by starting from a ‘non-sovereign’ understanding of truth

An extension of SPARQL for expressing qualitative preferences

In this paper we present SPREFQL, an extension of the SPARQL language that allows appending a PREFER clause that expresses "soft" preferences over the query results obtained by the main body of the query. The extension does not add expressivity and any SPREFQL query can be transformed to an equivalent standard SPARQL query. However, clearly separating preferences from the "hard" patterns and filters in the WHERE clause gives queries where the intention of the client is more cleanly expressed, an advantage for both human readability and machine optimization. In the paper we formally define the syntax and the semantics of the extension and we also provide empirical evidence that optimizations specific to SPREFQL improve run-time efficiency by comparison to the usually applied optimizations on the equivalent standard SPARQL query.Comment: Accepted to the 2017 International Semantic Web Conference, Vienna, October 201

Accuracy vs. Simplicity: A Complex Trade-Off

Inductive learning aims at finding general rules that hold true in a database. Targeted learning seeks rules for the predictions of the value of a variable based on the values of others, as in the case of linear or non-parametric regression analysis. Non-targeted learning finds regularities without a specific prediction goal. We model the product of non-targeted learning as rules that state that a certain phenomenon never happens, or that certain conditions necessitate another. For all types of rules, there is a trade-off between the rule's accuracy and its simplicity. Thus rule selection can be viewed as a choice problem, among pairs of degree of accuracy and degree of complexity. However, one cannot in general tell what is the feasible set in the accuracy-complexity space. Formally, we show that finding out whether a point belongs to this set is computationally hard. In particular, in the context of linear regression, finding a small set of variables that obtain a certain value of R2 is computationally hard. Computational complexity may explain why a person is not always aware of rules that, if asked, she would find valid. This, in turn, may explain why one can change other people's minds (opinions, beliefs) without providing new information.
