In recent years there has been a resurgence of interest in Hugo Gernsback, and the start of a serious study of the contribution he made to the development of science fiction. . . . It seemed to me that the time was due to reinvestigate the Gernsback era and dig into the facts surrounding the origins of Amazing Stories. I wanted to find out exactly why Hugo Gernsback had launched the magazine, what he was trying to achieve, and to consider what effects he had-good and bad. . . . Too many writers and editors from the Gernsback days have been unjustly neglected, or unfairly criticized. Now, I hope, Robert A. W. Lowndes and I have provided the grounds for a fair consideration of their efforts, and a true reconstruction of the development of science fiction. It's the closest to time travel you'll ever get. I hope you enjoy the trip."-Mike Ashley, Preface

Many national parks and monuments tell unique stories of the struggle between the rights of native peoples and the wants of the dominant society. These stories involve our greatest parks—Yosemite, Yellowstone, Mesa Verde, Glacier, the Grand Canyon, Olympic, Everglades—as well as less celebrated parks elsewhere. In American Indians and National Parks, authors Robert Keller and Michael Turek relate these untold tales of conflict and collaboration. American Indians and National Parks details specific relationships between native peoples and national parks, including land claims, hunting rights, craft sales, cultural interpretation, sacred sites, disposition of cultural artifacts, entrance fees, dams, tourism promotion, water rights, and assistance to tribal parks. Beginning with a historical account of Yosemite and Yellowstone, American Indians and National Parks reveals how the creation of the two oldest parks affected native peoples and set a pattern for the century to follow. Keller and Turek examine the evolution of federal policies toward land preservation and explore provocative issues surrounding park/Indian relations. When has the National Park Service changed its policies and attitudes toward Indian tribes, and why? How have environmental organizations reacted when native demands, such as those of the Havasupai over land claims in the Grand Canyon, seem to threaten a national park? How has the Park Service dealt with native claims to hunting and fishing rights in Glacier, Olympic, and the Everglades? While investigating such questions, the authors traveled extensively in national parks and conducted over 200 interviews with Native Americans, environmentalists, park rangers, and politicians. They meticulously researched materials in archives and libraries, assembling a rich collection of case studies ranging from the 19th century to the present. In American Indians and National Parks, Keller and Turek tackle a significant and complicated subject for the first time, presenting a balanced and detailed account of the Native-American/national-park drama. This book will prove to be an invaluable resource for policymakers, conservationists, historians, park visitors, and others who are concerned about preserving both cultural and natural resources.
TRB's National Cooperative Highway Research Program (NCHRP) Report 684: Enhancing Internal Trip Capture Estimation for Mixed-Use Developments explores an improved methodology to estimate how many internal trips will be generated in mixed-use developments - trips for which both the origin and destination are within the development. The methodology estimates morning and afternoon peak-period trips to and from six specific land use categories: office, retail, restaurant, residential, cinema, and hotel. The research team analyzed existing data from prior surveys and collected new data at three mixed-use development sites. The resulting methodology is incorporated into a spreadsheet model, which is available online for download.

Complex and unexplained phenomena tend to foster unorthodox perspectives. This publication is an example, as is a prior publication that emphasized the concept that intermediary metabolism might play a significant and determining role in hepatocyte proliferation and 1 tumorigenesis. Formulation of this hypothesis was based on an attempt to clarify several poorly understood phenomena; including the observations: 1) that xenobiotic peroxisome proliferators such as the fibrate hypolipidemic agents induce hepatocyte proliferation and carcinogenesis in rodents; 2) that benign and malignant liver tumors complicate the human syndrome of glycogen storage disease type I (glucose-6-phosphatase deficiency); and 3) that in this same syndrome, administration of glucose exerts an anti-tumor effect. Fatty acid and glucose metabolism are tightly linked in a we- established and profoundly inportant interplay. This connection, together with the fact that peroxisome proliferator-induced hepatocyte proliferation and carcinogenesis reflects inhibition of mitochondrial carnitine palmitoyltransferase-I and fatty acid oxidation, suggested the possibility that regulation of fatty acid metabolism could prove to be a pivotal determinant in the control of cell growth. In 1993, the year in which the paper cited above was published, insight into the importance of growth factors and signal transduction pathways in cell cycle regulation was increasing rapidly, but metabolic and energetic aspects of cell proliferation had attracted relatively little attention. Despite this, the concept seemed inescapable that the two seemingly distinct and unrelated determinants — signal transduction and metabolism — were integrally linked.
The first comprehensive history of Native American tribes in Wisconsin, this thorough and thoroughly readable account follows Wisconsin’s Indian communities—Ojibwa, Potawatomie, Menominee, Winnebago, Oneida, Stockbridge-Munsee, and Ottawa—from the 1600s through 1960. Written for students and general readers, it covers in detail the ways that native communities have striven to shape and maintain their traditions in the face of enormous external pressures. The author, Robert E. Bieder, begins by describing the Wisconsin region in the 1600s—both the natural environment, with its profound significance for Native American peoples, and the territories of the many tribal cultures throughout the region—and then surveys experiences with French, British, and, finally, American contact. Using native legends and historical and ethnological sources, Bieder describes how the Wisconsin communities adapted first to the influx of Indian groups fleeing the expanding Iroquois Confederacy in eastern America and then to the arrival of fur traders, lumber men, and farmers. Economic shifts and general social forces, he shows, brought about massive adjustments in diet, settlement patterns, politics, and religion, leading to a redefinition of native tradition. Historical photographs and maps illustrate the text, and an extensive bibliography has many suggestions for further reading.
When we think of baseball, we think of sunny days and leisurely outings at the ballpark--rarely do thoughts of death come to mind. Yet during the game's history, hundreds of players, coaches and spectators have died while playing or watching the National Pastime. In its second edition, this ground-breaking study provides the known details for 150 years of game-related deaths, identifies contributing factors and discusses resulting changes to game rules, protective equipment, crowd control and stadium structures and grounds. Topics covered include pitched and batted-ball fatalities, weather and field condition accidents, structural failures, fatalities from violent or risky behavior and deaths from natural causes.

The present volume describes the general properties of the thorium atom and ions, the thermodynamics of its compounds and solutions, the behavior of solutions and solid com pounds under the influence of its own radiation as well as an external radiation field, and spectroscopic data in great detail. The different chapters are of special interest to scientists who work in these fields, and also in the corresponding fields of other elements. In some special fields there exists a detailed knowledge of this radioelement whereas in other fields, such as M6Bbauer spectra, lower oxidation states, or radiation stability, there are large gaps. Due to the fact that the significance 23 of thorium as a breeder fuel ( 2"fh to be converted to fissile 233U after thermal neutron capture) has decreased within the last decade, the behavior of thorium is not as yet so thoroughly investigated as the heavier radioactive element uranium. Many of these data, however, are not only of academic interest, e.g., the knowledge of atomic spectra is needed for some analytical methods, especially in the trace concentration region. Due to the noble gaS-like electronic configuration of the tetravalent ion, there are no absorption bands in the visible region so that in general spectra and data are very scarce. This volume is a very detailed and critically reviewed compilation, written by experts from the Federal Republic of Germany, Belgium, and the United States.
The volume is concerned exclusively with all the binary species formed between the elements silicon and fluorine such as SiF, SiF2, SiF3, SiF4, and Sif62-. Most of the volume, i.e. 144 pages, is devoted to the description of the well known physical and chemical properties of the SiF4 as well as to its preparation. This is followed in length by the report on SiF2 with its interesting chemistry, along with a section on the diatomic radical SiF. Species with fivefold and sixfold coordination of silicon are exemplified by SiF5- and by the well known SiF62-. Interestingly, the detailed models for describing the bonding situation in both ions are still a matter of discussion. While for Si2F6 most of the basic data are known, information on the chemical and physical properties of the higher members of the acylic perfluorosilanes, SinF2n+2, is scarce. All available information on the unstable cyclic perfluorosilanes of composition (SiF2)n and some even more exotic species is also included.
When published in 1980, Benjamin B. Beck’s Animal Tool Behavior was the first volume to catalog and analyze the complete literature on tool use and manufacture in non-human animals. Beck showed that animals—from insects to primates—employed different types of tools to solve numerous problems. His work inspired and energized legions of researchers to study the use of tools by a wide variety of species. In this revised and updated edition of the landmark publication, Robert W. Shumaker and Kristina R. Walkup join Beck to reveal the current state of knowledge regarding animal tool behavior. Through a comprehensive synthesis of the studies produced through 2010, the authors provide an updated and exact definition of tool use, identify new modes of use that have emerged in the literature, examine all forms of tool manufacture, and address common myths about non-human tool use. Specific examples involving invertebrates, birds, fish, and mammals describe the differing levels of sophistication of tool use exhibited by animals.
This updated edition features three new chapters and current research findings. Topics include prenatal growth and functional development, motor development, thermoregulation, obesity in childhood and adolescence and more.
