The Emerging Strategic Balance
light. Indubitably the strategic balance between the two super powers is the most important strategic equation obtaining today. What differentiates the nuclear forces of the super powers from other nuclear powers is not the overwhelmingly larger number of atomic weapons available with them, but their technological capability quickly to reach higher levels of sophistication which can be attained by other nuclear powers only with very great difhculty. Besides intercontinental missiles (ICBMs), multiple warhead systems (MIRVs) and anti-ballistic missile (ABM) systems, they have at present reconnaissance satellites, communication satellites and satellite inter-
Can Nuclear Deterrence Last Out The Century
The autumn of last year marked half the road from the beginning of the nuclear era to the year 2000. Mankind has been spared nuclear devastation since the annihilation of two Japanese cities by the only two nuclear weapons then existing. But the destructiveness of nuclear arsenals, now increased many thousandfold, has sunk into human consciousness like man’s knowledge of his mortality.
Effects of signaling topic structure on text recall
Two experiments studied effects of signaling devices (headings, overviews, and summaries) on text memory. In Experiment 1, subjects read a text with or without signals, then recalled the topics of the text. Signaling produced better memory for the topics and their organization. In Experiment 2, subjects recalled the content of the text they read, and recalls were scored for the number of accurately recalled ideas. Signals produced recalls that were better organized by text topics. Signals also influenced the distribution of recall of ideas: Subjects remembered more topics but recalled less about each accessed topic if the text they read contained signals than if it did not
