Experimental Investigation of Impact in Landing on Water

Description: "The extent of agreement of the theoretical impact computations with the actual phenomenon has not as yet been fully clarified. There is on the one hand a certain imperfection in the theory (simplifying assumptions made) and on the other an insufficiency in the experimental data available. The object of our present paper is to show how far test results agree with the available approximate computation methods, to investigate in greater detail the physical nature of impact on water, and to perfect the experimental method of studying the phenomenon" (p. 1).

Philosophy Matters - Examining the Value of Knowledge

Description: This paper discusses the University of North Texas' (UNT) Center for the Study of Interdisciplinarity (CSID), where philosophers continue to examine the value of knowledge. The authors also discuss one example of CSID's work with the Comparative Assessment of Peer Review (CAPR) project. CAPR is a four-year project (2008-2012) studying the changing nature of peer review processes across six U.S. and foreign public science agencies. CAPR is funded by the U.S. National Science Foundation's (NSF) Science of Science and Innovation Policy (SciSIP) program.

Theory of the Landing Impact of Seaplanes

Description: The present investigation is an endeavor to express the jolting stresses, designated as landing impacts, undergone by seaplanes in landing and taking off from rough water, as functions of specific factors, in order to enable the evaluation of empirically obtained results and thus acquire theoretical data for the construction of seaplane floats and hulls.

GlobalWarming and Terrestrial Biodiversity Decline

Description: This study demonstrates that rapid rates of global warming are likely to increase rates of habitat loss and species extinction, most markedly in the higher latitudes of the Northern Hemisphere. Extensive areas of habitat may be lost to global warming and many species may be unable to shift their ranges fast enough to keep up with global warming. Rare and isolated populations of species in fragmented habitats or those bounded by large water bodies, human habitation and agriculture are particularly at risk, as are montane and arctic species.

Polar Bears at Risk

Description: Satisfactory monitoring information has been obtained for most polar bear populations in recent years, however there is concern about hunting in areas without formal quota systems, such as Greenland. A range of toxic pollutants, including heavy metals, radioactivity, and persistent organic pollutants (POPs) are found throughout the Arctic. Of greatest concern are the effects of POPs on polar bears, which include a general weakening of the immune system, reduced reproductive success and physical deformities. The expansion of oil development in the Arctic poses additional threats; for example, disturbances to denning females in the Arctic National Wildlife Refuge in Alaska could undermine recruitment of the Beaufort Sea polar bear population.

Coastal Alabama Offshore Natural Gas Economic Projection Model

Description: This document summarizes an economic projection model is third in a series of investigations concerning the social and economic impacts of the Coastal Alabama offshore gas industry. In addition to Alabama, this forecast concerns the economies of Texas and Louisiana as well. The results are based off the results from the study "Economic Effects of Coastal Alabama and Destin Dome Offshore Natural Gas Exploration, Development and Production."

Environmental Impacts of Synthetic Based Drilling Fluids

Description: This report covers the observed environmental impacts of synthetic based drilling fluids (SBF) that are used in deepwater oil drilling. It is found that SBF tends to accumulate in the sediment which tends to exhibit low toxicity and effects the living organisms in various ways.

Ecological Data in Support of the Tank Closure and Waste Management Environmental Impact Statement. Part 2: Results of Spring 2007 Field Surveys

Description: This review provides an evaluation of potential impacts of actions that have been proposed under various alternatives to support the closure of the high level waste tanks on the Hanford Site. This review provides a summary of data collected in the field during the spring of 2007 at all of the proposed project sites within 200 East and 200 West Areas, and at sites not previously surveyed. The primary purpose of this review is to provide biological data that can be incorporated into or used to support the Tank Closure and Waste Management Environmental Impact Statement.

The role of science and technology for energy and the environment

Description: The premise of this paper is that science, and the technology derived from science, is not the answer to energy and environmental problems. Science is a method of answering questions and as modern societies people must be very careful and specific in posing those questions. Many of the environmental issues addressed at the meeting are the direct result of not being specific enough in the demands placed on the science community. For example, when science was asked to increase chemical production to produce greater and greater quantities of consumer products, society forgot to ask that they be produced without significant damage to the environment. When society developed nuclear deterrents to protect national security interests, it failed to consider the life-cycle costs of these weapons systems. Now society must deal with a legacy of hundreds of billions of dollars in clean-up costs. One impediment has been that energy and environmental problems are intrinsically crosscutting, both across scientific disciplines and the decision-making systems of society. The author suggests that one approach to this problem is better integration across scientific disciplines and the integration of science and technology with political, economic and social factors. Three examples of successes are used to illustrate this.

Using Weather Data and Climate Model Output in Economic Analyses of Climate Change

Description: Economists are increasingly using weather data and climate model output in analyses of the economic impacts of climate change. This article introduces a set of weather data sets and climate models that are frequently used, discusses the most common mistakes economists make in using these products, and identifies ways to avoid these pitfalls. We first provide an introduction to weather data, including a summary of the types of datasets available, and then discuss five common pitfalls that empirical researchers should be aware of when using historical weather data as explanatory variables in econometric applications. We then provide a brief overview of climate models and discuss two common and significant errors often made by economists when climate model output is used to simulate the future impacts of climate change on an economic outcome of interest.

What is "Normative" at Cooling Water Intakes? Defining Normalcy Before Judging Adverse

Description: Judgments of adverse environmental impact from cooling water intake structures need to be preceded by an appreciation of what is normal. In its repo~ Return to the River, the Independent Scientd5c Group (now called the Independent Scientfilc Advisory Board) --the scientific peer review arm of the Northwest Power Planning Council-- advanced the notion of a "normative river ecosystem" as a new conceptual foundation for salrnonid recovery in the Columbia River basin. With this perspective, the sum of the best scientific understanding of how organisms and aquatic ecosystems function should be the norm or standard of measure for how we judge the effects of human activities on aquatic systems. ,For the best likelihood of recovery, key aspects of altered systems should be brought back toward nonnative (although not necessarily fully back to the historical or pristine state); new alterations should be judged for adversity by how much they move key attributes away from normative or what might be considered normal. In this presentation, I ask what "normative" is for the setting of cooling water intake structures and how this concept could help resolve long-standing disputes between groups interested in avoiding darnage to all organisms that might be entrained or impinged and those who take a more population or community perspective for judging adverse environmental impact. In essence, I suggest that if a water intake does not move the aquatic ecosystem outside the "normative" range, based on expressions of norrrdcy such as those discussed, then no adverse impact has occurred. Having an explicit baseline in normal or normative would place 316(b) analyses on the same conceptual foundation as 316(a) analyses, which strive to demonstrate the continuation of a balanced, indigenous community of aquatic organisms at the power station Iocation.
