These areas of knowledge have converged into a modern theory of epidemiology that has been slow to penetrate into textbooks, particularly at the introductory level. Epidemiology: An Introduction closes the gap. It begins with a brief, lucid discussion of causal thinking and causal inference and then takes the reader through the elements of epidemiology, focusing on the measures of disease occurrence and causal effects. With these building blocks in place, the reader learns how to design, analyze and interpret problems that epidemiologists face, including confounding, the role of chance, and the exploration of interactions. All these topics are layered on the foundation of basic principles presented in simple language, with numerous examples and questions for further thought.

    This book consists of six chapters arranged according to the different stages of research projects. Topics discussed include the different roles of business, engineering, and user-experience stakeholders; identification of research opportunities by developing empathy with stakeholders; and planning UX research with stakeholders. The book also offers ways of teaming up with stakeholders; strategies to improve the communication of research results to stakeholders; and the nine signs that indicate that research is making an impact on stakeholders, teams, and organizations. This book is meant for UX people engaged in usability and UX research. Written from the perspective of an in-house UX researcher, it is also relevant for self-employed practitioners and consultants who work in agencies. It is especially directed at UX teams that face no-time-no-money-for-research situations.

    It is surprising then that until now there has been no major one-volume reference devoted to the most widely dispersed and influential language of our time: the English language. A language-lover's dream, The Oxford Companion to the English Language is a thousand-page cornucopia covering virtually every aspect of the English language as well as language in general. The range of topics is remarkable, offering a goldmine of information on writing and speech (including entries on grammar, literary terms, linguistics, rhetoric, and style) as well as on such wider issues as sexist language, bilingual education, child language acquisition, and the history of English. There are biographies of Shakespeare, Noah Webster, Noam Chomsky, James Joyce, and many others whohave influenced the shape or study of the language; extended articles on everything from psycholinguistics to sign language to tragedy; coverage of every nation in which a significant part of the population speaks English as well as virtually every regional dialect and pidgin (from Gullah and Scouseto Cockney and Tok Pisin). In addition, the Companion provides bibliographies for the larger entries, generous cross-referencing, etymologies for headwords, a chronology of English from Roman times to 1990, and an index of people who appear in entries or bibliographies. And like all Oxford Companions, this volume is packed with delightful surprises. We learn, for instance, that the first Professor of Rhetoric at Harvard later became President (John Quincy Adams); that "slogan" originally meant "war cry"; that the keyboard arrangement QWERTY became popular not because it was efficientbut the opposite (it slows down the fingers and keeps them from jamming the keys); that "mbenzi" is Swahili for "rich person" (i.e., one who owns a Mercedes Benz); and that in Scotland, "to dree yir ain weird" means "to follow your own star." From Scrabble to Websters to TESOL to Gibraltar, the thirty-five hundred entries here offer more information on a wider variety of topics than any other reference on the English language. Featuring the work of nearly a hundred scholars from around the world, this unique volume is the ideal shelf-mate to The Oxford Companion to English Literature. It will captivate everyone who loves language.

    James Paul Gee begins his new book with 'I want to talk about vide games- yes, even violent video games - and say some positive things about them'. With this simple but explosive beginning, one of America's most well-respected professors of education looks seriously at the good that can come from playing video games. Gee is interested in the cognitive development that can occur when someone is trying to escape a maze, find a hidden treasure and, even, blasting away an enemy with a high-powered rifle. Talking about his own video-gaming experience learning and using games as diverse as Lara Croft and Arcanum, Gee looks at major specific cognitive activities: How individuals develop a sense of identity; How one grasps meaning; How one evaluates and follows a command; How one picks a role model; How one perceives the world.

    Kotter shows with compelling evidence what leadership really means today, why it is rarely associated with larger-than-life charismatics, precisely how it is different from management, and yet why both good leadership and management are essential for business success, especially for complex organizations operating in changing environments.The critics who despair of the coming of imaginative, charismatic leaders to replace the so-called manipulative caretakers of American corporations don't tell us much about what leadership actually is, or, for that matter, what management is either. Leadership, Kotter clearly demonstrates, is for the most part not a god-like figure transforming subordinates into superhumans, but is in fact a process that creates change -- a process which often involves hundreds or even thousands of "little acts of leadership" orchestrated by people who have the profound insight to realize this. Building on his landmark study of 15 successful general managers, Kotter presents detailed accounts of how senior and middle managers in major corporations, in close concert with colleagues and subordinates, were able to create a leadership process that put into action hundreds of commonsense ideas and procedures that, in combination with competent management, produced extraordinary results. This leadership turned NCR from a loser to a big winner in automated teller machines, despite intense competition from IBM. The same process at American Express and SAS helped businesses grow dramatically despite the fact that they were "mature" and "commodity-like." Kotter also shows how leadership turned around operations at P&G and Kodak; produced huge business successes at PepsiCo, ARCO, and ConAgra; and made the impossible occasionally happen at Digital. Thousands of companies today are overmanaged and underled, John Kotter concludes, not because managers lack charisma, but because far too few executives have a clear understanding of what leadership is and what it can accomplish. Without such a vision, even the most capable people have great difficulty trying to lead effectively and to create the cultures which will help others to lead.
