The humanitarians' tragedy: escapable and inescapable cruelties.
Paradoxically, elements of cruelty are intrinsic to the humanitarian enterprise.(1) This paper focuses on some of these. Escapable cruelties arise from technical failings, but the gradual professionalisation of the field and improvements in relief technologies mean that they have been significantly reduced in comparison to earlier eras. Other cruelties arise from clashes among rights, and the t...
متن کاملDifferential effects of escapable and inescapable footshock on hippocampal theta activity.
Three groups of rats were exposed to escapable shock, inescapable shock, or no shock using procedures known to induce learned helplessness effects. Twenty-four hours later, hippocampal electroencephalograms were recorded from freely moving subjects. A 5-s probe shock was delivered after 15 min, and recording continued. Frequency analyses revealed no differences between the pretreatment groups d...

Characteristics of emotional, behavioral, and physiological responses to pain are determined to a large extent by the behavioral significance of the pain, in particular to the degree to which the pain can be escaped. This review presents evidence that these different patterns of response depend on the activation of distinct pathways within the brain.
