The divergent predictions of 2 models of dual-task performance are investigated. The central bottleneck and central capacity sharing models argue that a central stage of information processing is capacity limited, whereas stages before and after are capacity free. The models disagree about the nature of this central capacity limitation. The central bottleneck model claims that central processin...

Some studies suggest that dual-task processing impairs sequence learning; others suggest it does not. The reason for this discrepancy remains obscure. It may have to do with the dual-task procedure often used. Many dual-task sequence learning studies pair the serial reaction time (SRT) task with a tone-counting secondary task. The tone-counting task, however, is not ideal for studying the cogni...

In this paper we give various equivalent characterizations of upper estimates of heat kernels of regular, conservative and local Dirichlet forms on doubling spaces, from both the analytic and probabilistic points of view. The first part of this paper uses purely analytic arguemtn, while the second part focuses on the probabilistic aspects where the exit time plays an important role.

The article deals with the sacred groves of the Balts in Lithuania and presents the linguistic background, the historical documents from the 12th– 18th century, the key folklore motifs of the topic, as well as selected examples of groves. The article also discusses possible relationships between pre-Christian religious traditions connected with the sacred groves and the ones which have survived...

The Master of Liberal Arts provides the chance to practice the methods of interdisciplinary inquiry that are the hallmark of a rigorous liberal arts education. As a student in the program, one can explore questions of identity through art, literature, and religion; analyze the politics of race in fiction, historical documents, the visual arts, and music; debate ethical choices presented by fict...

Document binarization is an active research area for many years. The choice of the most appropriate binarization algorithm for each case proved to be a very difficult procedure itself. In this paper, we propose a new technique for the validation of document binarization algorithms. Our method is simple in its implementation and can be performed on any binarization algorithm since it doesn’t req...

An enduring problem in electoral systems is that of "disproportionality," i.e., the mismatch between a party's percentage of the popular vote and its percentage of legislative seats. Such disproportionality is quite common and extreme cases are easy to find in the real word. To give just one example, the Liberal Party in Britain polled 13.8% of the national vote in 1979 but was rewarded with on...
