On Hearsay

I need to place the remarks that follow in context. And that means I need to acknowledge a number of heresies: I don’t like legal jargon; I don’t like the complexity of legal jargon; I don’t like the legal profession’s indifference to brevity; I don’t like the tendency of lawyers and judges always to be looking to the past for answers to novel questions; and I don’t consider law to be a science or remotely like a science. I want law to be simple and commonsensical and forward-looking. I take my judicial credo from a poem by the great Irish poet William Butler Yeats: “And I grew weary of the sun / Until my thoughts cleared up again, / Remembering that the best I have done / Was done to make it plain.” Or, in the words of another though lesser known poet, Ezra Pound, “MAKE IT NEW!

Foreword

[Excerpt] I first met John Hutson in 2005 when I was the Executive Director of Human Rights First. Human Rights First was working to challenge the use of cruelty by U.S. officials in security detentions, practices that had been used at Abu Ghraib, Guantanamo, and elsewhere after the attacks on September 11, 2001. We knew that the human rights community acting alone could not influence this debate, so we went looking for national security experts to help us challenge these practices

John R. Wooden, Stephen R. Covey and Servant Leadership: A Commentary

Ralph Waldo Emerson observed that consistency was the hobgoblin of little minds and that insight well underscores the challenges associated with accurately describing the leadership philosophy (and actions) of anyone - from coaches like John Wooden, leadership gurus like Steve Covey and Peter Drucker, philosophers like Aristotle and Socrates, or you and me. They are not always perfectly consistent, evolving, and even changing as situations and setting shift in both anticipated and unpredictable ways

Expected antenna utilization and overload

The trade-offs between the number of antennas at Deep Space Network (DSN) Deep-Space Communications Complex and the fraction of continuous coverage provided to a set of hypothetical spacecraft, assuming random placement of the space craft passes during the day. The trade-offs are fairly robust with respect to the randomness assumption. A sample result is that a three-antenna complex provides an average of 82.6 percent utilization of facilities and coverage of nine spacecraft that each have 8-hour passes, whereas perfect phasing of the passes would yield 100 percent utilization and coverage. One key point is that sometimes fewer than three spacecraft are visible, so an antenna is idle, while at other times, there aren't enough antennas, and some spacecraft do without service. This point of view may be useful in helping to size the network or to develop a normalization for a figure of merit of DSN coverage

Deep space communications, weather effects, and error control

Deep space telemetry is and will remain signal-to-noise limited and vulnerable to interference. A need exists to increase received signal power and decrease noise. This includes going to Ka-band in the mid-1990's to increase directivity. The effects of a wet atmosphere can increase the noise temperature by a factor of 5 or more, even at X-band, but the order of magnitude increase in average data rate obtainable at Ka-band relative to X-band makes the increased uncertainty a good trade. Lowbit error probabilities required by data compression are available both theoretically and practically with coding, at an infinitesimal power penalty rather than the 10 to 15 dB more power required to reduce error probabilities without coding. Advances are coming rapidly in coding, as with the new constraint-length 15 rate 1/4 convolutional code concatenated with the already existing Reed-Solomon code to be demonstrated on Galileo. In addition, high density spacecraft data storage will allow selective retransmissions, even from the edge of the Solar System, to overcome weather effects. In general, deep space communication was able to operate, and will continue to operate, closer to theoretical limits than any other form of communication. These include limits in antenna area and directivity, system noise temperature, coding efficiency, and everything else. The deep space communication links of the mid-90's and beyond will be compatible with new instruments and compression algorithms and represent a sensible investment in an overall end-to-end information system design

Anatomy of word and sentence meaning

Reading and listening involve complex psychological processes that recruit many brain areas. The anatomy of processing English words has been studied by a variety of imaging methods. Although there is widespread agreement on the general anatomical areas involved in comprehending words, there are still disputes about the computations that go on in these areas. Examination of the time relations (circuitry) among these anatomical areas can aid in under-standing their computations. In this paper we concentrate on tasks which involve obtaining the meaning of a word in isolation or in relation to a sentence. Our current data support a finding in the literature that frontal semantic areas are active well before posterior areas. We use the subject’s attention to amplify relevant brain areas involved either in semantic classification or in judging the relation of the word to a sentence in order to test the hypothesis that frontal areas are concerned with lexical semantics while posterior areas are more involved in comprehension of propositions that involve several words
