UC Santa Cruz Other Recent Work
UC Santa Cruz Other Recent Work Title Robert B. Stevens: UCSC Chancellorship, 1987-1991 Permalink https://escholarship.org/uc/item/95h8k9w0 Authors Stevens, Robert Jarrell, Randall Regional History Project, UCSC Library Publication Date 1999-05-21 Supplemental Material https://escholarship.org/uc/item/95h8k9w0#supplemental eScholarship.org Powered by the California Digital Library University of California Introduction The Regional History Project conducted six interviews with UCSC Chancellor Robert B. Stevens during June and July, 1991, as part of its University History series. Stevens was appointed the campus’s fifth chancellor by UC President David P. Gardner in July, 1987, and served until July, 1991. He was the second UCSC chancellor (following Chancellor Emeritus Robert L. Sinsheimer) recruited from a private institution. Stevens was born in England in 1933 and first came to the United States when he was 23. He was educated at Oxford University (B.A., M.A., B.C.L., and D.C.L.) and at Yale University (L.L.M.) and became an American citizen in 1971. An English barrister, Stevens has strong research interests in legal history and education in the United States and England. He served as chairman of the Research Advisory Committee of the American Bar Foundation, has written a half dozen books on legal history and social legislation, and numerous papers on American legal scholarship and comparative Anglo-American legal history. Prior to his appointment at UCSC he served for almost a decade as president of Haverford College from 1978 until 1987. From 1959 to 1976 he was a professor of law at Yale University. -

ARTICLE .1 Macro-Perspectives beyond the World System Joseph Voros Swinburne University of Technology Australia Abstract This paper continues a discussion begun in an earlier article on nesting macro-social perspectives to also consider and explore macro-perspectives beyond the level of the current world system and what insights they might reveal for the future of humankind. Key words: Macrohistory, Human expansion into space, Extra-terrestrial civilisations Introduction This paper continues a train of thought begun in an earlier paper (Voros 2006) where an approach to macro-social analysis based on the idea of "nesting" social-analytical perspectives was described and demonstrated (the essence of which, for convenience, is briefly summarised here). In that paper, essential use was made of a typology of social-analytical perspectives proposed by Johan Galtung (1997b), who suggested that human systems could be viewed or studied at three main levels of analysis: the level of the individual person; the level of social systems; and the level of world systems. Distinctions can be made between different foci of study. The focus may be on the stages and causes of change through time (termed diachronic), or it could be at some specific point in time (termed synchronic). As well, the focus may be on a specific single case (termed idiographic), in contrast to seeking regularities, patterns, or generalised "laws" (termed nomo- thetic). In this way, there are four main types of perspectives found at any particular level of analy- sis. This conception is shown here in slightly adapted form in Table 1.1 Journal of Futures Studies, February 2007, 11(3): 1 - 28 Journal of Futures Studies Table 1: Three Levels of Social Analysis Source: Adapted from Galtung (1997b). -

A Direct Communication Proposal to Test the Zoo Hypothesis

Given the >100 Received 3 March 2016 billion stars in our galaxy, many have argued that it is statistically unlikely that life, including intelligent Accepted 16 June 2016 life, has not emerged anywhere else. The lack of any sign of extraterrestrial intelligence, even though on a Available online 26 July 2016 cosmic timescale extraterrestrial civilizations would have enough time to cross the galaxy, is known as Fermi's Paradox. One possible explanation for Fermi's Paradox is the Zoo Hypothesis which states that Keywords: one or more extraterrestrial civilizations know of our existence and can reach us, but have chosen not to Active SETI disturb us or even make their existence known to us. I propose here a proactive test of the Zoo Hy- Astrobiology fi Fermi's Paradox pothesis. Speci cally, I propose to send a message using television and radio channels to any extrater- Messaging to extraterrestrial intelligence restrial civilization(s) that might be listening and inviting them to respond. Even though I accept this is METI unlikely to be successful in the sense of resulting in a response from extraterrestrial intelligences, the possibility that extraterrestrial civilizations are monitoring us cannot be dismissed and my proposal is consistent with current scientific knowledge. -

Searching for Extraterrestrial Intelligence
THE FRONTIERS COLLEctION THE FRONTIERS COLLEctION Series Editors: A.C. Elitzur L. Mersini-Houghton M. Schlosshauer M.P. Silverman J. Tuszynski R. Vaas H.D. Zeh The books in this collection are devoted to challenging and open problems at the forefront of modern science, including related philosophical debates. In contrast to typical research monographs, however, they strive to present their topics in a manner accessible also to scientifically literate non-specialists wishing to gain insight into the deeper implications and fascinating questions involved. Taken as a whole, the series reflects the need for a fundamental and interdisciplinary approach to modern science. Furthermore, it is intended to encourage active scientists in all areas to ponder over important and perhaps controversial issues beyond their own speciality. Extending from quantum physics and relativity to entropy, consciousness and complex systems – the Frontiers Collection will inspire readers to push back the frontiers of their own knowledge.

Inflation-Theory Implications for Extraterrestrial Visitation

Institute for Advanced Studies at Austin, 4030 W. Braker Ln., Suite 300, Austin, Texas 78759, USA. Email: [email protected] It has recently been argued that anthropic reasoning applied to inflation theory reinforces the prediction that we should find ourselves part of a large, galaxy-sized civilisation, thus strengthening Fermi’s paradox concern- ing “Where are they?” Furthermore, superstring and M-brane theory allow for the possibility of parallel universes, some of which in principle could be habitable. In addition, discussion of such exotic transport concepts as “traversable wormholes” now appears in the rigorous physics literature. As a result, the “We are alone” solution to Fermi’s paradox, based on the constraints of earlier 20th century viewpoints, appears today to be inconsistent with new developments in our best current physics and astrophysics theories. Therefore we reexamine and reevaluate the present assumption that extraterrestrials or their probes are not in the vicinity of Earth, and argue instead that some evidence of their presence might be found in certain high-quality UFO reports. This study follows up on previous arguments that (1) interstellar travel for advanced civilizations is not a priori ruled out by physical principles and therefore may be practicable, and (2) such advanced civilisations may value the search for knowledge from uncontaminated species more than direct, interspecies communica- tion, thereby accounting for apparent covertness regarding their presence.
