The Buffalo Commons: Its Antecedents and Their Implications
Over the last 150 years, the North American Great Plains, once a region of native grasses and wildlife, has become largely agricultural. During the same time, however, many have responded to the changes\u27 environmental, social and economic costs by proposing preservation. In the December 1987 issue of Planning, we contended that the future of the rural parts of the region lay in a vision we called the Buffalo Commons. To us the Buffalo Commons meant more bison and less cattle, more preservation and ecotourism and less conventional rural development and extraction--in short, a Great Plains that nurtured land uses that fell between intensive cultivation on the one side and wilderness on the other. The Buffalo Commons provoked much debate and led, directly or indirectly, to many public and private Plains initiatives that went in its direction. This article places our idea in historical context by examining it, its precedents, and the implications of both. In the Native American period the Plains amounted to a sort of Buffalo Commons. In the Euroamerican period numerous observers have suggested variations on Buffalo Commons-style preservation, conservation, or set-asides. George Catlin offered the earliest suggestion for a Great Plains Park in 1842, and the photographer L.A. Huffman had a similar idea in the early 1880s. The environmentally and politically restorationist Plains advocacy of the Indian prophet Wovoka led to the Wounded Knee Massacre in 1890. In the twentieth century proposals for versions of the Buffalo Commons came from the Agriculture Department official Lewis Gray; Interior Department Secretary Harold Ickes; biologist V.H. Cahalane; economist Herbert Stein; geographers Daniel Luten and Bret Wallach; and novelists Sharon Butala, Tom Clancy, James Michener and (in the twenty-first century) Annie Proulx, among many others. The Buffalo Commons is effective in part because it echoes this broad and varied group of thinkers. We suggest that the long-term persistence of such a controversial idea means that portions of it will continue to find success as well as resistance
Overview of the fifth international conference on the effects of noise on aquatic life
The Effects of Noise on Aquatic Life took place in Den Haag, the Netherlands, in July 2019. The potential effects on animals ranging from plankton, shrimps, crabs, and lobsters, to fishes, seals, dolphins, and whales were discussed. Reported effects include behavioral responses, auditory masking, cardiac rate changes, stress, a temporary loss of hearing, and perhaps more serious tissue and organ damage. Short-term and long-term, individual and population-level effects were portrayed. Several studies also looked at the fundamentals of animal sound production and perception. One session dealt with the regulation and management of underwater noise. Another integral part of the meeting focused on the sounds and sound sources that might affect aquatic life. As a consequence, underwater noise from pile driving, seismic surveying, shipping, and sonars, as well as from non-anthropogenic sources such as wind and waves was examined. The social program was intended to encourage more leisurely discussions amongst conference participants in order to facilitate networking and the strengthening of relationships. The feedback from conference delegates (submitted via an online survey after the meeting) was very positive
Consistent use of paradoxes in deriving constraints on the dynamics of physical systems and of no-go-theorems
The classical methods used by recursion theory and formal logic to block
paradoxes do not work in quantum information theory. Since quantum information
can exist as a coherent superposition of the classical ``yes'' and ``no''
states, certain tasks which are not conceivable in the classical setting can be
performed in the quantum setting. Classical logical inconsistencies do not
arise, since there exist fixed point states of the diagonalization operator. In
particular, closed timelike curves need not be eliminated in the quantum
setting, since they would not lead to any paradoxical outcome controllability.
Quantum information theory can also be subjected to the treatment of
inconsistent information in databases and expert systems. It is suggested that
any two pieces of contradicting information are stored and processed as
coherent superposition. In order to be tractable, this strategy requires
quantum computation.Comment: 10 pages, latex, no figure
The chromospherically--active binary CF Tuc revisited
New high-resolution spectra, of the chromospherically active binary system CF
Tuc, taken at the Mt. John University Observatory in 2007, were analyzed using
two methods: cross-correlation and Fourier--based disentangling. As a result,
new radial velocity curves of both components were obtained. The resulting
orbital elements of CF Tuc are: = AU,
= AU, =
, and = . The cooler
component of the system shows H and CaII H & K emissions. Our
spectroscopic data and recent light curves were solved simultaneously
using the Wilson-Devinney code. A dark spot on the surface of the cooler
component was assumed to explain large asymmetries observed in the light
curves. The following absolute parameters of the components were determined:
= , = ,
= , = ,
= and = . The
orbital period of the system was studied using the O-C analysis. The O-C
diagram could be interpreted in terms of either two abrupt changes or a
quasi-sinusoidal form superimposed on a downward parabola. These variations are
discussed by reference to the combined effect of mass transfer and mass loss,
the Applegate mechanism and also a light-time effect due to the existence of a
massive third body (possibly a black hole) in the system. The distance to CF
Tuc was calculated to be pc from the dynamic parallax, neglecting
interstellar absorption, in agreement with the Hipparcos value.Comment: 33 pages, 10 figures, accepted for publication by MNRA
Offshore wind energy development: Research priorities for sound and vibration effects on fishes and aquatic invertebrates
Author Posting. © Acoustical Society of America, 2022. This article is posted here by permission of Acoustical Society of America for personal use, not for redistribution. The definitive version was published in Journal of the Acoustical Society of America 151(1), (2022): 205–215, https://doi.org/10.1121/10.0009237.There are substantial knowledge gaps regarding both the bioacoustics and the responses of animals to sounds associated with pre-construction, construction, and operations of offshore wind (OSW) energy development. A workgroup of the 2020 State of the Science Workshop on Wildlife and Offshore Wind Energy identified studies for the next five years to help stakeholders better understand potential cumulative biological impacts of sound and vibration to fishes and aquatic invertebrates as the OSW industry develops. The workgroup identified seven short-term priorities that include a mix of primary research and coordination efforts. Key research needs include the examination of animal displacement and other behavioral responses to sound, as well as hearing sensitivity studies related to particle motion, substrate vibration, and sound pressure. Other needs include: identification of priority taxa on which to focus research; standardization of methods; development of a long-term highly instrumented field site; and examination of sound mitigation options for fishes and aquatic invertebrates. Effective assessment of potential cumulative impacts of sound and vibration on fishes and aquatic invertebrates is currently precluded by these and other knowledge gaps. However, filling critical gaps in knowledge will improve our understanding of possible sound-related impacts of OSW energy development to populations and ecosystems.Support for this project was provided by New York State Energy Research and Development Authority (Agreement #118972)
Science and Ideology in Economic, Political, and Social Thought
This paper has two sources: One is my own research in three broad areas: business cycles, economic measurement and social choice. In all of these fields I attempted to apply the basic precepts of the scientific method as it is understood in the natural sciences. I found that my effort at using natural science methods in economics was met with little understanding and often considerable hostility. I found economics to be driven less by common sense and empirical evidence, then by various ideologies that exhibited either a political or a methodological bias, or both. This brings me to the second source: Several books have appeared recently that describe in historical terms the ideological forces that have shaped either the direct areas in which I worked, or a broader background. These books taught me that the ideological forces in the social sciences are even stronger than I imagined on the basis of my own experiences.
The scientific method is the antipode to ideology. I feel that the scientific work that I have done on specific, long standing and fundamental problems in economics and political science have given me additional insights into the destructive role of ideology beyond the history of thought orientation of the works I will be discussing
Hypertrophic osteoarthropathy and rheumatoid arthritis. Simultaneous occurrence in association with diffuse interstitial fibrosis
A patient is described who was treated with high-dose prednisone in an attempt to halt progressive respiratory insufficiency associated with diffuse interstitial fibrosis. On cessation of steroid therapy the patient was noted to have radiologic manifestations of hypertrophic osteoarthropathy (HOA) as well as clinical and laboratory features of rheumatoid arthritis (RA). Subsequently a diffuse vasculitis developed with bowel perforation and sepsis leading to death.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37728/1/1780190319_ftp.pd
We Are History: The Outlines of a Quasi-Substantive Philosophy of History
In times of a felt need to justify the value of the humanities, the need to revisit and re-establish the public relevance of the discipline of history cannot come as a surprise. On the following pages I will argue that this need is unappeasable by scholarly proposals. The much desired revitalization of historical writing lies instead in reconciling ourselves with the dual meaning of the word history, in exploring the necessary interconnection between history understood as the course of events and as historical writing. Despite the general tendency of the last decades to forbid philosophizing about history in the former sense (at least in departments of history and philosophy), I think that to a certain extent we already do so without succumbing to substantive thought. We already have the sprouts of a speculative although only quasi-substantive philosophy of history that nevertheless takes seriously the postwar criticism of the substantive enterprise. In this essay I will first try to outline this quasi-substantive philosophy of history that attests to the historical sensibility of our times; and second, I will try to outline its consequences regarding history as historical writing. Finally, in place of a conclusion I will suggest that historical writing is not as much a contribution to public agendas as it is the very arena in which public life is at stake
