Ergastava transkraniaalse magnetstimulatsiooni mõju petukäitumisele

The present study investigated the effects of excitation of the dorsolateral prefrontal cortex (DLPFC) with repetitive transcranial magnetic stimulation (rTMS) on deceptive behaviour. The event-related potential (ERP) component P300 is well known as a neural marker of deception. P300 amplitude was examined in response to critical, familiar, and neutral stimuli in a task similar to the concealed information test. The electroencephalography (EEG) of 13 volunteers was recorded combined with rTMS. We did not find a difference in response to rTMS between right and left DLPFC as initially expected. However, TMS elicited a higher mean P300 amplitude to the critical stimulus compared to sham condition. Therefore, noninvasive prefrontal cortex excitation by rTMS can be used to increase the sensitivity of P300 to critical items in an analogue of the concealed information test

The Coming Multi-Order World

The article shows that the current international system is changing towards a completely new form of international system, conceptualized as a multi-order system. The suggestion for a multi-order world stands in contrast to three current narratives about the future global order expressed through a multipolar narrative; a multi-partner narrative and a multi-culture narrative. The article demonstrates that although each narrative points to a plausible future, neither fully captures what lies ahead. Using English School concepts such as order, international society, international system and primary and secondary institutions, the article reveals a conception of the coming international system as a system consisting of several different ‘orders’ (or international societies) nested within an overall international system. In the coming ‘multi-order world’, the liberal order will continue, and may even be strengthened internally, but its global reach will be a thing of the past. Moreover, the challenge in a multi-order world will be to forge new forms of relationships between composite and diverse actors across complex lines of division and convergence. Scholars and policy-makers should note that the coming multi-order world will be radically different, requiring new thinking and new institutions and the acceptance of diversity in both power and principle

Advancing student achievement through labor-management collaboration

[Excerpt] One of the most contentious issues unfolding in the political landscape of the United States is public education optimization and reform. While the United States represents the world’s largest and most diverse economy, it ranks “average” at best when it comes to public school education as a whole, and markedly worse in the math and science disciplines. Making matters even more bleak, states such as Wisconsin, Ohio, and Indiana have mandated deep educational cuts in the face of extreme budget pressure, which has made reform and advancement even more of a tenuous suggestion

Impact of Forecast Errors on Expansion Planning of Power Systems with a Renewables Target

This paper analyzes the impact of production forecast errors on the expansion planning of a power system and investigates the influence of market design to facilitate the integration of renewable generation. For this purpose, we propose a stochastic programming modeling framework to determine the expansion plan that minimizes system-wide investment and operating costs, while ensuring a given share of renewable generation in the electricity supply. Unlike existing ones, this framework includes both a day-ahead and a balancing market so as to capture the impact of both production forecasts and the associated prediction errors. Within this framework, we consider two paradigmatic market designs that essentially differ in whether the day-ahead generation schedule and the subsequent balancing re-dispatch are co-optimized or not. The main features and results of the model set-ups are discussed using an illustrative four-node example and a more realistic 24-node case study

Parapositronium Decay and Dispersion Relations

Positronium decay rates are computed at the one-loop level, using convolution-type factorized amplitudes. The dynamics of this factorization is probed with dispersion relations, showing that unallowed approximations are usually made, and some ordre alpha^2 corrections missed. Further, we discuss the relevance of the Schrodinger wavefunction as the basis for perturbative calculations. Finally, we apply our formalism to the parapositronium two-photon decay.Comment: LaTeX, 13 pages, 1 eps figur
