In recent years there has been an exponential rise in the number of studies employing transcranial direct current stimulation (tDCS) as a means of gaining a systems-level understanding of the cortical substrates underlying behaviour. These advances have allowed inferences to be made regarding the neural operations that shape perception, cognition, and action. Here we summarise how tDCS works, a...

This paper describes the OpenURL Framework, both the original ‘de facto’ standard version 0.1, and the NISO standard Z39.88-2004, ‘The OpenURL Framework for Context-Sensitive Services’. The explanation is illustrated by examples from Zetoc, a journal article and conference paper current awareness service available in the UK. Various emerging novel uses of the OpenURL Framework are described. Ev...

Zunächst wird der Prototyp eines elektronischen Diskussionsforums für das Internet beschrieben, wobei auf dessen Systemeigenschaften, die Implementation auf Basis des Konstanzer Hypertext-Systems (KHS) und auf bestehende Anwendungen eingegangen wird. Daran anschließend wird das Konzept einer Erweiterung dieses Systems beschrieben, mit dem es mehreren Benutzern zeitversetzt möglich ist, Beiträge...

On April 26, 1996, Public Law 104-134 was Chart 1 .-Payment volume, by type of disbursement, fiscal year 1997 enacted, requiring all Federal payments except tax refunds be issued electronically by January 2, 1999, thus beginning a new era in electronic N Federal tax 10.5% funds transfer (EFT). This legislation, the Debt Collection Improvement Act of 1996-part of the Omnibus Consolidated Resciss...

We study the double parton interaction process in collisions between highly virtual qq̄ pairs in the BFKL regime. Explicit expressions for the double parton distributions are obtained both in the case of direct coupling of the BFKL pomerons to the qq̄ pair and in the case of triple pomeron interaction.

Recently there has been a proposal for modified gravitational f(R) actions which include a direct coupling between the matter action and the Ricci scalar, R. Of particular interest is the specific case where both the action and the coupling are linear in R. It is shown that such an action leads to a theory of gravity which includes higher order derivatives of the matter fields without introduci...

OBJECTIVE To evaluate the relative effectiveness of different policies in attracting nurses to rural areas in Kenya, South Africa and Thailand using data from a discrete choice experiment (DCE). METHODS A labelled DCE was designed to model the relative effectiveness of both financial and non-financial strategies designed to attract nurses to rural areas. Data were collected from over 300 grad...

Although direct manipulation (DM) has been considered a potentially inappropriate interface style for learnware, convincing indication that the problem with DM lies rather on “what is manipulated” than on the “manipulation” itself has been obtained from empirical studies in the domain of Euclidean geometry. A semiotic examination of such findings suggests that there may be theoretically-based c...
