Districtly Speaking: Evenwel v. Abbott and the Apportionment Population Debate

The Equal Protection Clause of the Fourteenth Amendment, as interpreted by the Supreme Court, promises substantial equality of population within state legislative districts under the “one-person, one-vote” rule. Most frequently, total population is the basis for state reapportionament, but state citizenship and voter registration populations have also been acceptable bases in certain situations. The case of Evenwel v. Abbott, provides the Court with the opportunity to resolve the permissible population basis for reapportionment of state legislative districts. This Commentary argues that a state may rely upon total population as the basis for apportionment because such an approach is consistent with existing precedent and would avoid arbitrary administration based on volatile and uncertain statistical evidence related to voting patterns

Multimodal One-Shot Learning of Speech and Images

Imagine a robot is shown new concepts visually together with spoken tags, e.g. "milk", "eggs", "butter". After seeing one paired audio-visual example per class, it is shown a new set of unseen instances of these objects, and asked to pick the "milk". Without receiving any hard labels, could it learn to match the new continuous speech input to the correct visual instance? Although unimodal one-shot learning has been studied, where one labelled example in a single modality is given per class, this example motivates multimodal one-shot learning. Our main contribution is to formally define this task, and to propose several baseline and advanced models. We use a dataset of paired spoken and visual digits to specifically investigate recent advances in Siamese convolutional neural networks. Our best Siamese model achieves twice the accuracy of a nearest neighbour model using pixel-distance over images and dynamic time warping over speech in 11-way cross-modal matching.Comment: 5 pages, 1 figure, 3 tables; accepted to ICASSP 201

The use of a DMT to monitor the stability of the slopes of a clay exploitation pit in the Boom clay in Belgium

In Belgium the Boom Clay is a well known overconsolidated clay formation. This Tertiary clay, with the same geological origin as the London Clay, is used for the fabrication of bricks, roofing tiles. In the article is described how the DMT can be used to evaluate the stability of slopes, to determine the risk of instability and how the cause of the failure directly could be related to the results of the DMT-measurement. The results of the tests before the period of instability, during the period of instability and after stabilization are discussed. The KD-value is a representative value to judge the risk of instability

I/O-optimal algorithms on grid graphs

Given a graph of which the n vertices form a regular two-dimensional grid, and in which each (possibly weighted and/or directed) edge connects a vertex to one of its eight neighbours, the following can be done in O(scan(n)) I/Os, provided M = Omega(B^2): computation of shortest paths with non-negative edge weights from a single source, breadth-first traversal, computation of a minimum spanning tree, topological sorting, time-forward processing (if the input is a plane graph), and an Euler tour (if the input graph is a tree). The minimum-spanning tree algorithm is cache-oblivious. The best previously published algorithms for these problems need Theta(sort(n)) I/Os. Estimates of the actual I/O volume show that the new algorithms may often be very efficient in practice.Comment: 12 pages' extended abstract plus 12 pages' appendix with details, proofs and calculations.

After a career break: supporting women returning to ICT

This is a case study of an initiative to support women returning to ICT after a career break, which was run in the UK and Ireland between 2005 and 2011.The article starts by outlining how the UK government’s concern about women failing return to SET careers led to the setting up of a national campaign (RETURN) to address this issue. A brief overview of previous research about women’s reasons for leaving ICT employment and the difficulties and barriers they encounter in returning to work, sets the context for the development of the online course Return to SET. An outline of the course and its innovative support model is then described followed by a discussion about measurement of impact and concluding with some suggestions for future developmen
