This book covers recent advances in efficiency evaluations, most notably Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) methods. It introduces the underlying theories, shows how to make the relevant calculations and discusses applications. The aim is to make the reader aware of the pros and cons of the different methods and to show how to use these methods in both standard and non-standard cases. Several software packages have been developed to solve some of the most common DEA and SFA models. This book relies on R, a free, open source software environment for statistical computing and graphics. This enables the reader to solve not only standard problems, but also many other problem variants. Using R, one can focus on understanding the context and developing a good model. One is not restricted to predefined model variants and to a one-size-fits-all approach. To facilitate the use of R, the authors have developed an R package called Benchmarking, which implements the main methods within both DEA and SFA. The book uses mathematical formulations of models and assumptions, but it de-emphasizes the formal proofs - in part by placing them in appendices -- or by referring to the original sources. Moreover, the book emphasizes the usage of the theories and the interpretations of the mathematical formulations. It includes a series of small examples, graphical illustrations, simple extensions and questions to think about. Also, it combines the formal models with less formal economic and organizational thinking. Last but not least it discusses some larger applications with significant practical impacts, including the design of benchmarking-based regulations of energy companies in different European countries, and the development of merger control programs for competition authorities.

Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.

The virgin forests of longleaf pine, bald cypress and oak that covered much of the South Carolina Lowcountry presented seemingly limitless opportunity for lumbermen. Henry Buck of Maine moved to the South Carolina coast and began shipping lumber back to the Northeast for shipbuilding. He and his family are responsible for building the "Henrietta," the largest wooden ship ever built in the Palmetto State. Buck was followed by lumber barons of the late nineteenth and early twentieth centuries who forever changed the landscape, clearing vast tracts to supply lumber to the Northeast. The devastating environmental legacy of this shipbuilding boom wasn't addressed until 1937, when the International Paper Company opened the largest single paper mill in the world in Georgetown and began replanting hundreds of thousands of acres of trees. Local historian Robert McAlister presents this epic story of the ebb and flow of coastal South Carolina's lumber industry.

“From the ring of the ax in the woods, to the scream of the saw blade in the mill, to the founding of many of Wisconsin’s communities, Jerry Apps does an outstanding job bringing Wisconsin’s logging and lumbering heritage to life.”—Kerry P. Bloedorn, director, Rhinelander Pioneer Park Historical Complex For more than half a century, logging, lumber production, and affiliated enterprises in Wisconsin’s Northwoods provided jobs for tens of thousands of Wisconsinites and wealth for many individuals. The industry cut through the lives of nearly every Wisconsin citizen, from an immigrant lumberjack or camp cook in the Chippewa Valley to a Suamico sawmill operator, an Oshkosh factory worker to a Milwaukee banker. When the White Pine Was King tells the stories of the heyday of logging: of lumberjacks and camp cooks, of river drives and deadly log jams, of sawmills and lumber towns and the echo of the ax ringing through the Northwoods as yet another white pine crashed to the ground. He explores the aftermath of the logging era, including efforts to farm the cutover (most of them doomed to fail), successful reforestation work, and the legacy of the lumber and wood products industries, which continue to fuel the state’s economy. Enhanced with dozens of historic photos, When the White Pine Was King transports readers to the lumber boom era and reveals how the lessons learned in the vast northern forestlands continue to shape the region today.
