Parallel distractor rejection as a binding mechanism in search.

The relatively common experimental visual search task of finding a red X amongst red O's and green X's (conjunction search) presents the visual system with a binding problem. Illusory conjunctions (ICs) of features across objects must be avoided and only features present in the same object bound together. Correct binding into unique objects by the visual system may be promoted, and ICs minimized, by inhibiting the locations of distractors possessing non-target features (e.

The theory and prevention of genocide.

The development of a social-scientific theory of genocide has been neglected by most social scientists, viewed with suspicion by several Holocaust scholars, and advanced in a fragmentary and confused manner by those few scholars who have committed themselves to this task. This paper attempts to clarify the problems which confront those attempting a social theory of genocide and proposes solutions which, while recognising a necessary pluralism in social science methodology, seek to clear the way for the advance of theory construction. A theoretical account of genocide is proposed which draws on work in the social sciences and in genocide studies.
