School is the main scenario of social actions where the foundations of interpersonal relations other than those of the family are laid down; it has therefore become one of the main settings for psychoeducational research. In recent years, the phenomena of poor interpersonal relations, gratuitous and cruel aggression, the resulting victimization, and the construction of a psychopathic and inmora...

Sometimes network resources including IP address, MAC address, and hostname could be misused for the weakness of TCP/IP protocol suite and the deficiency of network management. Therefore, there is urgent need to solve the problems from the viewpoint of network management and operation. In this paper, we propose a network network blocking algorithm based on ARP spoofing and evaluate the robustne...

The degradation of agmatine to succinate by Klebsiella aerogenes occurs in five steps. The enzyme catalyzing the first step, agmatinase, is induced by agmatine. The enzymes catalyzing the second and third steps, putrescine aminotransferase and 4-aminobutyraldehyde dehydrogenase, are induced by putrescine and also by their product, 4-aminobutyrate. The enzymes catalyzing the fourth and fifth ste...

In this paper, we construct a type of dynamic closed-loop supply chain network (CLSCN) model with dual-channel (the traditional channel and the Internet channel), time-delays and uncertainties of cost parameters, gratuitous return rate, remanufacturing/recycling/disposal rates, customer preference rate and customer demand. Furthermore, in order to improve the robustness of CLSCN, we propose a r...

Supererogatory acts are considered by some to be part of medicine, whereas others accept supererogation to be a gratuitous virtue, to be extolled when present, but not to be demanded. The present paper sides with those contending that medicine is duty-bound to benefit patients and that supererogation/altruism must per definition remain outside and beyond any role-description of the profession. ...

existence of suffering in life is undeniable. but, why does suffering exist? what is its cause? are there any meanings for this life? is it possible to escape from suffering? dostoyevsky, who believes that suffering is an inherent element of human life, tries to represent the problem of suffering and men's reactions to it in his works. he believes that not only suffering does exist, but al...

Oxalurate, the gratuitous inducer of the allantoin degradative enzymes, was taken into the cell by an energy-dependent active transport system with an apparent Km of 1.2 mM. Efflux of previously accumulated oxalurate was rapid, with a half-life of about 2 min. The oxalurate uptake system appears to be both constitutively produced and insensitive to nitrogen catabolite repression. The latter obs...

Mobile Ad Hoc Network (MANET) is a self-organized and infrastructure-less mobile network. Wireless Mesh Networks is self-configuration; self-healing and low cost adhoc network. Ad-hoc On-demand Distance Vector (AODV), in MANETs is an on-demand variation of the distance vector routing protocol. This protocol initiate route discovery only when a route is needed and maintain active routes only whi...

M. O'Sullivan and P. Ekman (2004) claim to have discovered 29 wizards of deception detection. The present commentary offers a statistical critique of the evidence for this claim. Analyses reveal that chance can explain results that the authors attribute to wizardry. Thus, by the usual statistical logic of psychological research, O'Sullivan and Ekman's claims about wizardry are gratuitous. Even ...

When a group of individuals creates something, credit is usually divided among them. Oddly, that does not apply to scientific papers. The most commonly used performace measure for individual researchers is the h-index, which does not correct for multiple authors. Each author claims full credit for each paper and each ensuing citation. This mismeasure of achievement is fuelling a flagrant increa...
