Book Description
Shrimp is easily America’s favorite seafood, but its very popularity is the wellspring of problems that threaten the shrimp industry’s existence. Asian-Cajun Fusion: Shrimp from the Bay to the Bayou provides insightful analysis of this paradox and a detailed, thorough history of the industry in Louisiana. Dried shrimp technology was part of the cultural heritage Pearl River Chinese immigrants introduced into the Americas in the mid-nineteenth century. As early as 1870, Chinese natives built shrimp-drying operations in Louisiana’s wetlands and exported the product to Asia through the port of San Francisco. This trade internationalized the shrimp industry. About three years before Louisiana’s Chinese community began their export endeavors, manufactured ice became available in New Orleans, and the Dunbar family introduced patented canning technology. The convergence of these ancient and modern technologies shaped the evolution of the northern Gulf Coast’s shrimp industry to the present. Coastal Louisiana’s historic connection to the Pacific Rim endures. Not only does the region continue to export dried shrimp to Asian markets domestically and internationally, but since 2000 the region’s large Vietnamese immigrant population has increasingly dominated Louisiana’s fresh shrimp harvest. Louisiana shrimp constitute the American gold standard of raw seafood excellence. Yet, in the second decade of the twenty-first century, cheap imports are forcing the nation’s domestic shrimp industry to rediscover its economic roots. “Fresh off the boat” signs and real-time internet connections with active trawlers are reestablishing the industry’s ties to local consumers. Direct marketing has opened the industry to middle-class customers who meet the boats at the docks. This “right off the boat” paradigm appears to be leading the way to reestablishment of sustainable aquatic resources. All-one-can-eat shrimp buffets are not going to disappear, but the Louisiana shrimp industry’s fate will ultimately be determined by discerning consumers’ palates.

Book Description
In the post--World War II era, Louisiana's coastal wetlands underwent an industrial transformation that placed the region at the center of America's energy-producing corridor. By the twenty-first century the Louisiana Gulf Coast supplied nearly one-third of America's oil and gas, accounted for half of the country's refining capacity, and contributed billions of dollars to the U.S. economy. Today, thousands of miles of pipelines and related infrastructure link the state's coast to oil and gas consumers nationwide. During the course of this historic development, however, the dredging of pipeline canals accelerated coastal erosion. Currently, 80 percent of the United States' wetland loss occurs on Louisiana's coast despite the fact that the state is home to only 40 percent of the nation's wetland acreage, making evident the enormous unin-tended environmental cost associated with producing energy from the Gulf Coast. In American Energy, Imperiled Coast Jason P. Theriot explores the tension between oil and gas development and the land-loss crisis in Louisiana. His book offers an engaging analysis of both the impressive, albeit ecologically destructive, engineering feats that characterized industrial growth in the region and the mounting environmental problems that threaten south Louisiana's communities, culture, and "working" coast. As a historian and coastal Louisiana native, Theriot explains how pipeline technology enabled the expansion of oil and gas delivery -- examining previously unseen photographs and company records -- and traces the industry's far-reaching environmental footprint in the wetlands. Through detailed research presented in a lively and accessible narrative, Theriot pieces together decades of political, economic, social, and cultural undertakings that clashed in the 1980s and 1990s, when local citizens, scientists, politicians, environmental groups, and oil and gas interests began fighting over the causes and consequences of coastal land loss. The mission to restore coastal Louisiana ultimately collided with the perceived economic necessity of expanding offshore oil and gas development at the turn of the twenty-first century. Theriot's book bridges the gap between these competing objectives. From the discovery of oil and gas below the marshes around coastal salt domes in the 1920s and 1930s to the emergence of environmental sciences and policy reforms in the 1970s to the vast repercussions of the BP/Deepwater Horizon oil spill in 2010, American Energy, Imperiled Coast ultimately reveals that the natural and man-made forces responsible for rapid environmental change in Louisiana's wetlands over the past century can only be harnessed through collaboration between public and private entities.

Book Description
In The Place with No Edge, Adam Mandelman follows three centuries of human efforts to inhabit and control the lower Mississippi River delta, the vast watery flatlands spreading across much of southern Louisiana. He finds that people’s use of technology to tame unruly nature in the region has produced interdependence with—rather than independence from—the environment. Created over millennia by deposits of silt and sand, the Mississippi River delta is one of the most dynamic landscapes in North America. From the eighteenth-century establishment of the first French fort below New Orleans to the creation of Louisiana’s Coastal Master Plan in the 2000s, people have attempted to harness and master this landscape through technology. Mandelman examines six specific interventions employed in the delta over time: levees, rice flumes, pullboats, geophysical surveys, dredgers, and petroleum cracking. He demonstrates that even as people seemed to gain control over the environment, they grew more deeply intertwined with—and vulnerable to—it. The greatest folly, Mandelman argues, is to believe that technology affords mastery. Environmental catastrophes of coastal land loss and petrochemical pollution may appear to be disconnected, but both emerged from the same fantasy of harnessing nature to technology. Similarly, the levee system’s failures and the subsequent deluge after Hurricane Katrina owe as much to centuries of human entanglement with the delta as to global warming’s rising seas and strengthening storms. The Place with No Edge advocates for a deeper understanding of humans’ relationship with nature. It provides compelling evidence that altering the environment—whether to make it habitable, profitable, or navigable —inevitably brings a response, sometimes with unanticipated consequences. Mandelman encourages a mindfulness of the ways that our inventions engage with nature and a willingness to intervene in responsible, respectful ways.

Book Description
The Marksville site, which is believed to be contemporaneous with and connected to Hopewell sites in Ohio and Illinois, is in Avoyelles Parish in central Louisiana, in the Lower Mississippi Valley. In this volume, Alan Toth compiles information drawn from three early archaeological excavations at Marksville. The excavations were led by Gerard Fowke in 1926; Frank M. Setzler and James A. Ford in 1933; and Robert S. Neitzel and Edwin B. Doran in 1939. Includes a ceramic analysis for all three excavations, black and white photographs of ceramics, and 14 tables of ceramic counts.

Book Description
It is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. Rather, common practice is to categorize them under the heading `stratigraphic excavation'. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time - a point little appreciated by modern archaeologists. Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils. The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously. Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques. Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history. This text will appeal to all archaeologists, from graduate students to seasoned professionals, who want to learn more about the backbone of archaeological dating.

Book Description
Abstract: The micro method of hematocrit is rapidly replacing red cell counts in clinical hematology. Observations were made on the value of this method in routine hematological examination of trouts. Under the conditions of data collection, the normal hematocrit values for brook trout were 45 to 50, for brown trout 39 to 44, and for rainbow trout 45 to 53. There was a close correlation between the hematocrits, red cell counts and hemoglobin. The commercial heparinized capillaries, while excellent for human blood, tend to give somewhat higher readings (7 to 18 percent) with trout, due to incomplete prevention of blood coagulation. The procedure as applied to trout is described in detail.
