The inequality of bargaining power between employees who do not possess full freedom of association or actual liberty of contract and employers who are organized in the corporate or other forms of ownership association substantially burdens and affects the flow of commerce, and tends to aggravate recurrent business depressions, by depressing wage rates and the purchasing power of wage earners i...

Indirect aggression includes behaviours such as criticizing a competitor's appearance, spreading rumours about a person's sexual behaviour and social exclusion. Human females have a particular proclivity for using indirect aggression, which is typically directed at other females, especially attractive and sexually available females, in the context of intrasexual competition for mates. Indirect ...

The cultural defense has been the subject of a great deal of recent scholarship. Much of this analysis has concerned the consequences of the cultural defense, both for defendants and victims. Scholars differ on what these unintended consequences may be, however, and identify effects ranging from encouraging American ideals to spreading racism, to legitimizing violence against women. Although se...

Prior theory suggests that reputation spreading (e.g., gossip) and punishment are two key mechanisms to promote cooperation in groups, but no behavioral research has yet examined their relative effectiveness and efficiency in promoting and maintaining cooperation. To examine these issues, we observed participants interacting in a four-round public goods game (PGG) with or without gossip and pun...

OBJECTIVE To examine co-occurrence of five subtypes of peer victimization. METHODS Data were obtained from a national sample of 7,475 US adolescents in grades 6 through 10 in the 2005/2006 Health Behavior in School-Aged Children (HBSC) study. Latent class analyses (LCA) were conducted on victimization by physical, verbal, social exclusion, spreading rumors, and cyber bullying. RESULTS Three...

In social psychology, emotional contagion describes the widely observed phenomenon of one person’s emotions being influenced by surrounding people’s emotions. While the overall effect is agreed upon, the underlying mechanism of the spread of emotions has seen little quantification and application to computational agents. In this paper, we explore computational models of emotional contagion by i...

Introduction: Studies by Frey et al. [1,2] and Frey [3,4] indicate the northern lowlands of Mars have been in existence for nearly all of martian history, predating even the very large impacts Hellas, Argyre and Isidis. Large populations of “Quasi-Circular Depressions” (QCDs) were observed in the northern lowlands in MOLA data where few impacts were visible in surface imagery. These “non-visibl...

New evidence concerning the pathophysiology of migraine has come from the results of therapeutic transcranial magnetic stimulation (tTMS). The instantaneous responses to single pulses applied during the aura or headache phase, together with a number of other observations, make it unlikely that cortical spreading depression is involved in migraine. tTMS is considered to act by abolishing abnorma...

Introduction: Repetitive cortical spreading depression (CSD) can lead to cell death in immature brain tissue. Caspases are involved in neuronal cell death in several CSD-related neurological disorders. Yet, whether repetitive CSD itself can induce caspase activation in adult or juvenile tissue remains unknown. Inducing repetitive CSD in somatosensory cortices of juvenile and adult rats in vivo,...

cortical spreading depression (csd) are associated with dramatic failure of brain ion homeostasis, efflux of excitatory amino acids from nerve cells, increased energy metabolism and changes in cerebral blood flow. there is strong clinical and experimental evidence to suggest that csd is involved in the mechanism of migraine, stroke, subarachnoid hemorrhage and traumatic brain injury. therefore,...
