Hawaii's Hottest Issue: Update On Geothermal Development, Paul Faulstich

Pitzer Faculty Publications and Research

Walking through Hawai'i's Wao Kele O Puna rainforest, you can hear the coarse volcanic soil crunch underfoot. A surrealistic calm lingers in the thick air while songbirds call out from the understory. Yet this is a forest under siege.

Geothermal developers want to tap the volcanic heat beneath the Wao Kele O Puna forest and use it to make electricity and profits.

Malaysian Deforestation Proceeds Apace, Paul Faulstich

Pitzer Faculty Publications and Research

A hunger fast, dubbed Fast Action, was staged in front of the Japanese Consulate General in Honolulu on July 20 to protest the destruction of the most ancient and biologically diverse ecosystem on Earth. Organized by Hawai'i Earth First! and the O'ahu Rainforest Action Group, Fast Action was designed to alert people to the destruction of tropical rainforests in Sarawak, Malaysia. Protesters demanded on immediate moratorium on the cutting of rainforests in,which the Penan and other-native peoples live.

Hawaiians Fight For The Rainforest, Paul Faulstich

Pitzer Faculty Publications and Research

On March 25, 141 were arrested as part of the largest demonstration yet against the drilling of geothermal wells in the Wao Kele O Puna Rainforest on the Big Island of Hawaii. The geothermal project, undertaken by True Geothermal Company and endorsed by Hawaii's governor and other high-powered, short-sighted people, has already invaded the largest intact tropical lowland rainforest in the United States. The demonstration drew over 1500 protesters,

Graphs, Maneuvers, And Turnpikes, Arthur T. Benjamin

All HMC Faculty Publications and Research

We address the problem of moving a collection of objects from one subset of Z^m to another at minimum cost. We show that underfairly natural rules for movement assumptions, if the origin and destination are far enough apart, then a near optimal solution with special structure exists: Our trajectory from the originto the destination accrues almost all of its cost repeatingat most m different patterns of movement. Directions for related research are identified.

Size‐Inconsistency Effects In Molecular Properties For States With Valence‐Rydberg Mixing: The Low‐Lying Π→Π∗ States Of Ethylene And Butadiene, Robert J. Cave

All HMC Faculty Publications and Research

Ab initio results for the low‐lying 1B1u states of ethylene are used to discuss size‐inconsistency effects on calculated molecular properties for states where valence‐Rydberg mixing is important. Results for the expectation value of x2, x being the coordinate perpendicular to the plane of the molecule, are presented from quasidegenerate variational perturbation theory and multireference configuration‐interaction calculations. These results are compared with values from previous studies. It is argued that size inconsistency in configuration‐interaction studies can have a significant effect on estimated molecular properties. Calculations on several low‐lying states of butadiene are also reported where similar size‐inconsistency effects are found.

Hawaii's Rainforest Crunch: Land, People, And Geothermal Development, Paul Faulstich

Pitzer Faculty Publications and Research

One hundred and forty-one people, led by Native Hawaiians, were arrested on 25 March 1990 as part of the largest demonstration yet against geothermal development in Hawaii. The gathering was intended to focus attention on Native Hawaiian rights and the ecological consequences of drilling geothermal wells in the near-pristine Wao Kele O Puna rain forest. The energy project, undertaken by True Geothermal Company and endorsed by Hawaii's governor and other imposing figures, has already invaded the largest intact tropical lowland rain forest in the United States.

Olmos Park And The Creation Of A Suburban Bastion, Char Miller, Heywood T. Sanders

Pomona Faculty Publications and Research

An examination of this small Texas community will also cast light on the larger world of which it was a part. The development of Olmos Park, then, was inextricably bound up with and reflective of the political machinations and social problems that dominated San Antonio in the first decades of this century. As Mauerman understood, the suburb was a fragment of the urban whole, an observation that needs to be pushed one step farther. The forces that shaped Olmos Park and determined its relations with San Antonio were also part of a national pattern, of tensions generated by the explosive …

The Rise Of Urban Texas, Char Miller, David R. Johnson

Pomona Faculty Publications and Research

Texas contains three of the nation's ten largest cities, but their existence has not yet affected the hold that the state's rural heritage has on Texas' imagination--or so Texans' attachment to two nineteenth-century cultural landmarks, the Alamo and the Chisholm Trail, would suggest. As the shrine of Texas liberty, the Alamo continually generates elegies to the manly courage and bravery of the fallen heroes of 1836.

Ordered Ultraconnected Rings, Melvin Henriksen, Frank A. Smith

All HMC Faculty Publications and Research

A ring R with identity element 1 is called ultraconnected if for each unital homomorphism ϕ of Z^ω into R, there is an i < ω such that ϕ(f) = f(i) • 1 for every f € Z^ω . Our main result is that if no sum of nonzero squares in R is 0 and R has only trivial idempotents, then R fails to be ultraconnected iff R contains a subring isomorphic to Z^ω/P for some free minimal prime ideal P of Z^ω.

Faster Circuits And Shorter Formulas For Multiple Addition, Multiplication And Symmetric Boolean Functions, Michael Paterson, Uri Zwick, Nicholas Pippenger

All HMC Faculty Publications and Research

A general theory is developed for constructing the shallowest possible circuits and the shortest possible formulas for the carry-save addition of n numbers using any given basic addition unit. More precisely, it is shown that if BA is a basic addition unit with occurrence matrix N, then the shortest multiple carry-save addition formulas that could be obtained by composing BA units are of size n1p+o(1)/, where p is the unique real number for which the Lp norm of the matrix N equals 1. An analogous result connects the delay matrix M of the basic addition unit BA and the minimal …
