There is ample evidence that emotions affect performance. Positive emotions can improve performance, while negative ones may diminish it. For example, the fears induced by the possibility of failure or of negative evaluations have physiological consequences (shaking, loss of concentration) that may impair performance in sports, on stage or at school. There is also ample evidence that individual...

— It is shown that it is possible to achieve complete formal symmetrization in the electron and proton quantum theory by means of a new quantization process. The meaning of Dirac equations is somewhat modified and there is no longer any reason to speak of negative-energy states nor to assume, for any other types of particles, especially neutral ones, the existence of antiparticles, correspondin...

This meta-analysis of 57 primary studies with 73,933 students shows strong links between affective teacher-student relationships (TSRs) and students' externalizing behavior problems (EBPs). Moreover, students' culture, age, gender, and the report types of EBPs moderated these effects. The negative correlation between positive indicators of affective TSRs and students' EBPs was stronger (a) amon...

Japanese dare-mo has been widely acknowledged to be an NPI, furthermore, a “strict” NPI in the sense of Giannakidou (2011) as it seems to be licensed only in an “antiveridical” environment, specifically, with a clausemate negation. However, there is a type of positive sentences in which dare-mo can appear, i.e. non-episodic sentences, which indicates that dare-mo is in fact not an NPI and its N...

While standard models of risky choice account for the first and second statistical moments of reward outcome distributions (mean and variance, respectively), they often ignore the third moment, skewness. Determining a decision-maker's attitude about skewness is useful because it can help constrain process models of the mental steps involved in risky choice. We measured three rhesus monkeys' pre...

Growing load and deterioration of the environment can be interpreted as a result of some external effects interventions. While the positive externalities influence the positive productional and utilizational functions of other subjects, the negative externalities influence the negative ones. Both types of external effects can act as parcial or global externalities. Linking of environmental issu...

conclusions optimization of medium composition and synergistic antimicrobial activity on the cyanobacteria could lead to production of effective antimicrobials. results c. leptolyngbya had antimicrobial activity individually and in synergy with antibiotics against gram-positive and gram-negative bacteria. the highest activity of the chloroform extract was on gram positive strains and its effect...

Motivated by problems of comparative genomics and paleogenomics, we introduce the Gapped Consecutive-Ones Property Problem (k,δ)-C1P: given a binary matrix M and two integers k and δ, can the columns of M be permuted such that each row contains at most k sequences of 1’s and no two consecutive sequences of 1’s are separated by a gap of more than δ 0’s. The classical C1P problem, which is known ...

We investigate the complexity of bit counting algorithms in different sets of instructions.

In this paper we address the problem of identifying what local properties the sub-components of a system have to satisfy in order to guarantee a (security) property on the behaviour of the whole system. We associate each action with a value. Hence, we end up with quantitative properties on them, which are specified through a modal logic equipped with a parametric algebraic structure (i.e., a c-...
