Map projection concerns the science of mathematical cartography, the techniques by which the Earth's dimensions, shape and features are translated in map form, be that two-dimensional paper or two- or three- dimensional electronic representations. The central focus of this book is on the theory of map projections. Mathematical cartography also takes in map scales and their variation, the division of maps into sets of sheets and nomenclature, and addresses the problems of making measurements and conducting investigations which make use of geodetic measurements and the development of graphical methods for solving problems of spherical trigonometry, marine- and aeronavigation, astronomy and even crystallography.

With the advance of science and technology, there have been breakthroughs in the field of classical research and methods of map projection. Among these, computer science and space science have had the greater influence upon the field of research and the formation of a working body of map projection, developing them in breadth and depth.This book reflects several aspects of the development of modern mathematical cartography, especially the theory and methods of map projection transformation. Map projection transformation is an area of research in mathematical cartography newly developed over the last 25 years. It is widely used in surveying and computer-assisted cartography, data processing for information systems, and the transformation of data from space, remote sensing, and other space sciences. The development of map projection transformation not only expands new areas of research on mathematical cartography, but it also further develops the applied area with the creation and application of map projection transformation software and mapping mathematics bases on the computer.

Genre -- the articulation of "kind" -- is one of the oldest and most continuous subjects of theoretical and critical commentary. Yet from Romanticism to postmodernism, the concept of genre has been punched with so many holes that today it hardly seems graspable, let alone viable. By combining theory with dialectical literary histories of three significantly different genres -- tragedy, satire, and the essay -- John Snyder reconstructs genre as the figural deployment of symbolic power.One purpose of this approach is to reconcile the recent dismantling of representational and classificatory genres with the incipient notion in post-Althusser Marxism that genre is the crucial mediation between history and aesthetics. Snyder extends certain implications of Aristotle, Benjamin, Bakhtin, Foucault, and Serres. He also offers the first antisystem yet comprehensive genre theory to serve as a fully distinct alternate to Frye's formalist and Genette's structuralist schemes.Finally, Snyder's theory of genre as power opens a way to a fundamentally new theory of literature itself: that aesthetic language deployed as power organizes itself as generic intervention. Three historically dynamic configurations establish the range of all possible genres -- tragedy as power politically deployed as mimesis, satire as power rationally deployed as rhetoric, and the essay as power textually deployed as constative rhetoric.Specific analyses developing this important new theory cover a broad spectrum of literature, from classical to contemporary. Other genres, different media, and a variety of subgenres and modes political and religious -- all acquire fresh significance from the elaborations of Snyder's three selected genres.

Sales forecasting and market analysis are the cornerstones of the planning process. Yet, these two tasks are usually performed by people with only limited training in either area because most firms do not have full-time forecasters/market analysts. The authors acknowledge this situation and attempt to describe the key techniques for forecasting sales and analyzing markets in a format that meets the needs of an audience with limited quantitative skills. In addition to its basic approach, another strength of this book is that it combines the coverage of two key activities--forecasting and market analysis--that are performed by the same person in most middle-sized (and smaller) firms.The book's contents and format were designed with two audiences in mind: persons assigned to develop forecasts and market analyses, but who are not specialists in either area, and persons who will be incorporating these results in their planning and decision making. The major portion of the book is devoted to the three basic categories of forecasting models--time series, causal, and judgmental--emphasizing the most widely used models in each category. Special attention is also given to the sources for obtaining the data needed to make forecasts and analyze markets. The latter part of the book describes procedures for developing market and sales potentials, methods for segmenting markets, and some analytic techniques such as conjoint analysis and cluster analysis, gaining increased usage among market analysts.

Sometimes the road to forgiveness and restoration can be a rocky one. Set in Chicago and Baltimore in 1944 with flashbacks to the 1920s, JACOB'S BELL follows Jacob MacCallum on his arduous journey to redemption. At one time, Jacob had it all: wealth, a wonderful family and a position as one of the most respected businessmen in Chicago. Then he made some bad decisions and all that changed. For the past twenty years he lived in an alcohol-induced haze, riddled with guilt for the dreadful things he had done to his family and his role in the untimely death of his wife. Estranged from his children and penniless, he was in and out of jail, on the street and jumping freight trains for transportation. Realizing he needed a drastic change, Jacob embarked on a journey to find his children, seek their forgiveness, and restore his relationship with them. Befriended by a pastor at a Salvation Army mission, he struggled to transform his life. Yet finally he overcame his demons, but not without a fair number of setbacks. Jacob became a Salvation Army Bell Ringer at Christmastime. While ringing his bell on a street corner one snowy day, he met a young girl who, through a series of strange coincidences, led him back to his children and facilitated Jacob's forgiveness just in time for Christmas. Author John Snyder pens a story of love, hardship, and reconciliation that will leave readers filled with Christmas joy.

Tourism throughout the world raises environmental issues that are often concerned with conflicting rights and responsibilities: the inherent right of mankind to travel, the no-less inherent right of indigenous people to guard their environmental heritage, and the responsibility of governments - local, national or (in the unique case of Antarctica) international - to protect environments over which they exercise stewardship. Additionally, the presence of international commercial enterprises, especially marine and other mass transport modes, represent unique governance challenges.This book deals mainly with environmental issues and the management implications arising from polar tourism, one of the fastest-growing sectors of world tourism. However, many of the issues discussed here arise no less urgently in temperate and tropical wilderness areas, and indeed in any region where sensitive environments are subjected to mass tourism. The principles and guidelines discussed here are of interest and practical use in tourism studies generally.
