Jack Holloway works alone, for reasons he doesn't care to talk about. Hundreds of miles from ZaraCorp's headquarters on planet, 178 light-years from the corporation's headquarters on Earth, Jack is content as an independent contractor, prospecting and surveying at his own pace. As for his past, that's not up for discussion. Then, in the wake of an accidental cliff collapse, Ja...(展开全部)

Jack Holloway works alone. Hundreds of miles from ZaraCorp's headquarters on planet, 178 light-years from the corporation's headquarters on Earth, Jack is content as an independent contractor. As for his past, that's not up for discussion. Then, in the wake of an accidental cliff collapse, Jack discovers a seam of unimaginably valuable jewels, to which he manages to lay legal c...(展开全部)

In this innovative approach to the practice of social science, Charles Ragin explores the use of fuzzy sets to bridge the divide between quantitative and qualitative methods. Paradoxically, the fuzzy set is a powerful tool because it replaces an unwieldy, "fuzzy" instrument (the variable, which establishes only the positions of cases relative to each other) with a precise one (...(展开全部)

This classic introduction to the main areas of mathematical logic provides the basis for a first graduate course in the subject. It embodies the viewpoint that mathematical logic is not a collection of vaguely related results, but a coherent method of attacking some of the most interesting problems, which face the mathematician. The author presents the basic concepts in an unus...(展开全部)

Undergraduate students with no prior classroom instruction in mathematical logic will benefit from this evenhanded multipart text by one of the centuries greatest authorities. Part I offers an elementary but thorough overview of mathematical logic of first order. Part II introduces some of the newer ideas and the more profound results of logical research in the twentieth centur...(展开全部)

Textbook taking a logical approach to the study and instruction of economics, offering a rigorous college-level course, attempting to integrate disciplines associated with economics, such as business, finance and sociology, into the traditional instruction. Looks at both macroeconomics and microeconomics, another unique feature. Softcover.

This introduction to first-order logic clearly works out the role of first-order logic in the foundations of mathematics, particularly the two basic questions of the range of the axiomatic method and of theorem-proving by machines. It covers several advanced topics not commonly treated in introductory texts, such as Fraisse's characterization of elementary equivalence, Lindstro...(展开全部)

Assuming no previous study in logic, this informal yet rigorous text covers the material of a standard undergraduate first course in mathematical logic, using natural deduction and leading up to the completeness theorem for first-order logic. At each stage of the text, the reader is given an intuition based on standard mathematical practice, which is subsequently developed wit...(展开全部)

This is an advanced 2001 textbook on modal logic, a field which caught the attention of computer scientists in the late 1970s. Researchers in areas ranging from economics to computational linguistics have since realised its worth. The book is for novices and for more experienced readers, with two distinct tracks clearly signposted at the start of each chapter. The development i...(展开全部)
