Report on Meteorological Research March 1, 1935 (m-1)
No full textThe object of the report was to elucidate in detail the various features of the research program in meteorology being carried on at the Daniel Guggenheim Airship Institute in Akron, Ohio. Mr. L. J. Fangman, of the U.S. Weather Bureau, was collaborating with the author in carrying out work such as a study of autographic records of the various meteorological elements during frontal passages with a view to the possible prediction of the intensity of the accompanying disturbance as it may affect the operation of aircraft and a study of atmospheric gustiness with a view to finding the dependence between frequency end amplitude of velocity fluctuations and the vertical temperature and velocity gradients

Are traditional thinking and decision-making techniques adequate for developing sustainable water systems?
No full text'The problems we have today cannot be solved by thinking the way we thought when we created them' (Einstein). Many water systems planned or constructed prior to the 1990s did not consider the concept of sustainability and were based on traditional technical thinking, analytical processes and decision-making techniques. The question now is, can we develop sustainable water systems by using the same thinking and decision making techniques? A model has been presented that develops sustainability as a journey, balancing economic, environmental and social factors in both spatial and temporal dimensions. Over time, the number, complexity, variety and interconnectedness of factors required for managing water resource projects have increased. Analytical or economic techniques are no longer sufficient or appropriate, and inputting the data into a black box for analysis would appear unnecessary.Bernadette A. Foley and Trevor M. Daniel
Defoe's Foes:The Author as Character
No full textThe most famous fictional Defoe features in J. M. Coetzee’s Foe (1986), in which he conjures Robinson Crusoe out of a memoir by a “true” castaway. Harrumphing across the country alongside the modern-day narrator of Stuart Campbell’s Daniel Defoe’s Railway Journey (2017), a surreal iteration quite literally leaps out of the pages of a Penguin Classics edition of his real-life counterpart’s travel writing. Setting aside a long tradition of neo-Georgian novels in which Defoe cameos as a seventeenth-century spy, a Defoe-as-character only for all intents and purposes, this chapter attends to two complex cases in the genre of author fictions: Coetzee’s Foe and Campbell’s Defoe
Short-term response of herpetofauna to timber harvesting in conjuction with streamside-management zones in seasonally-flooded bottomland-hardwood forests of southeast Texas
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references.Impacts of selection-cutting and clearcutting on local herpetofauna populations were evaluated. Also, the effectiveness of a streamside-management zone (SMZ) implemented within harvested areas was assessed. Research was conducted at Forest Lake Forest and Wildlife Research Station, located in southeast Tyler County, Texas. A randomized block design experiment was used. Three 24-ha blocks, bisected lengthwise by an intermittent stream, were subdivided into three (8-ha) plots consisting of a control, selection-cut, and clearcut. A SMZ was established 20. 1-m from each bank of the intermittent stream and subjected only to limited selection-cutting. Herpetofauna were censused using 144 drift fence arrays, consisting of pit-fall and double-ended-wire funnel traps. Traps were checked for 180 days, between 24 January 1993 and 22 June 1994. During this time, 8194 individual reptiles and amphibians comprising 38 species were captured. Differences in abundance between control and both timber harvesting treatments and between SMZ within control and SMZ within both timber harvesting treatments were analyzed utilizing a one-way ANOVA and multiple comparison tests for the 15 most commonly captured species. The remaining 23 species were rarely encountered, preventing meaningful statistical evaluation. Selection-cutting did not decreased abundance of any species. Selection-cutting increased abundance of 2 species and had no effect on the remaining 13 species. Clearcutting decreased abundance of one species. Clearcutting increased abundance of 3 species and had no impact on I I species. No species decreased in abundance in SMZs of either selection-cut or clearcut plots. Two species increased in abundance in SMZs implemented within selection-cuts. Two species increased in abundance in SMZs implemented within clearcuts. Both selection-cut and clearcut treatments possessed greater species diversities than control areas. In addition, selection-cut and clearcut Sws possessed greater species diversities than control SMZS. In the short-term, genotypic species of seasonally-flooded-bottomland forests suffer greatest impact after timber harvest, while more generalist species remain stable or increase in abundance. Selection-cutting appeared to have the least harmful effect on herpetofauna, as this method maintains the essence of natural forests by allowing heterogeneity in stand age and habitat. The continued use of SMZs is recommended. These areas provide a refugium and may act as centers of dispersal for detrimentally impacted species to repopulate the new emerging forest

American Roulette: The Effect of Reminders of Death on Support for George W. Bush in the 2004 Presidential Election
No full textAn experiment was conducted to assess the effect of a subtle reminder of death on voting intentions for the 2004 U.S. presidential election. On the basis of terror management theory and previous research, we hypothesized that a mortality salience induction would increase support for President George W. Bush and decrease support for Senator John Kerry. In late September 2004, following a mortality salience or control induction, registered voters were asked which candidate they intended to vote for. In accord with predictions, Senator John Kerry received substantially more votes than George Bush in the control condition, but Bush was favored over Kerry following a reminder of death, suggesting that President Bush's re-election may have been facilitated by non conscious concerns about mortality in the aftermath of September 11, 2001.This is an electronic version of the article published in Analyses of Social Issues and Public Policy, 5(1):177-187, 2005 Dec.The definitive version is available at www3.interscience.wiley.co
Perspective:Sign Epistasis and Genetic Constraint on Evolutionary Trajectories
No full textEpistasis for fitness means that the selective effect of a mutation is conditional on the genetic background in which it appears. Although epistasis is widely observed in nature, our understanding of its consequences for evolution by natural selection remains incomplete. In particular, much attention focuses only on its influence on the instantaneous rate of changes in frequency of selected alleles via epistatic contribution to the additive genetic variance for fitness. Thus, in this framework epistasis only has evolutionary importance if the interacting loci are simultaneously segregating in the population. However, the selective accessibility of mutational trajectories to high fitness genotypes may depend on the genetic background in which novel mutations appear, and this effect is independent of population polymorphism at other loci. Here we explore this second influence of epistasis on evolution by natural selection. We show that it is the consequence of a particular form of epistasis, which we designate sign epistasis. Sign epistasis means that the sign of the fitness effect of a mutation is under epistatic control; thus, such a mutation is beneficial on some genetic backgrounds and deleterious on others. Recent experimental innovations in microbial systems now permit assessment of the fitness effects of individual mutations on multiple genetic backgrounds. We review this literature and identify many examples of sign epistasis, and we suggest that the implications of these results may generalize to other organisms. These theoretical and empirical considerations imply that strong genetic constraint on the selective accessibility of trajectories to high fitness genotypes may exist and suggest specific areas of investigation for future research
