Numerical analysis presents different faces to the world. For mathematicians it is a bona fide mathematical theory with an applicable flavour. For scientists and engineers it is a practical, applied subject, part of the standard repertoire of modelling techniques. For computer scientists it is a theory on the interplay of computer architecture and algorithms for real-number calculations. The tension between these standpoints is the driving force of this book, which presents a rigorous account of the fundamentals of numerical analysis of both ordinary and partial differential equations. The point of departure is mathematical but the exposition strives to maintain a balance between theoretical, algorithmic and applied aspects of the subject. In detail, topics covered include numerical solution of ordinary differential equations by multistep and Runge-Kutta methods; finite difference and finite elements techniques for the Poisson equation; a variety of algorithms to solve large, sparse algebraic systems; methods for parabolic and hyperbolic differential equations and techniques of their analysis. The book is accompanied by an appendix that presents brief back-up in a number of mathematical topics. Dr Iserles concentrates on fundamentals: deriving methods from first principles, analysing them with a variety of mathematical techniques and occasionally discussing questions of implementation and applications. By doing so, he is able to lead the reader to theoretical understanding of the subject without neglecting its practical aspects. The outcome is a textbook that is mathematically honest and rigorous and provides its target audience with a wide range of skills in both ordinary and partial differential equations.

Beginning with the 1988 presidential election and now updated through 2004, The Nightly News Nightmare shows how network news coverage of what is arguably the nation's most important political event has declined. Through extensive analysis of news content from the 'Big Three' and Fox, acclaimed media scholars Farnsworth and Lichter compare what the candidates said with what the networks say they said and judge the disparity a nightmare. The authors go on to suggest that perhaps the candidates themselves do a better job of portraying the campaigns than those who used to be the trusted network guardians of the news. While making clear that overall coverage of the Bush-Kerry race marked an improvement compared to previous elections, Farnsworth and Lichter also point out that in other ways, things were worse.

American presidents often engage in intensive campaigns to obtain public support for their policy initiatives. This core strategy for governing is based on the premise that if presidents are skilled enough to exploit the “bully pulpit,” they can successfully persuade or even mobilize public opinion on behalf of their legislative goals. In this book, George Edwards analyzes the results of hundreds of public opinion polls from recent presidencies to assess the success of these efforts. Surprisingly, he finds that presidents typically are not able to change public opinion; even great communicators usually fail to obtain the public’s support for their high-priority initiatives. Focusing on presidents’ personae, their messages, and the American public, he explains why presidents are often unable to move public opinion and suggests that their efforts to do so may be counterproductive. Edwards argues that shoring up previously existing support is the principal benefit of going public and that “staying private”—negotiating quietly with elites—may often be more conducive to a president’s legislative success.

Message Control_a look at what shapes the news from the presidential campaign trail_comes out of the author's experience traveling with campaigns, interviews with other journalists who have covered campaigns from the road, and research on campaign news. Elizabeth Skewes, a journalism professor and former reporter, investigates journalists' beliefs and the role those beliefs play in the election process, as well as how the routines of campaign reporting affect news coverage. While Skewes does find that journalists make an effort to inform the voting decisions of their readers by giving them a sense of context for each campaign and each candidate's character, she also shows that journalists remain wary of staff manipulation and are constrained by pack journalism, press pools, and life 'in the bubble.' From on-the-trail perspectives to media theory explanations, Message Control begins to answer the question of why political coverage focuses on personalities and peccadilloes when studies show the public wants less of this and more discussion of political issues.

Since the election of Richard Nixon in 1968 to Donald Trump’s victory in 2016, both presidential campaigns and television news have undergone significant changes, perhaps most noticeably in the use of public opinion polls in campaign reporting by the national evening newscasts of ABC, CBS, and NBC. The Influence of Polls on Television News Coverage of Presidential Campaigns explores how during the past 50 years the three networks have quadrupled their use of polls during general election campaigns while the amount of time spent covering the actual issues facing the nation has dwindled. The increasing focus on polls over the years by television news has resulted in an overall diminished quality of journalism which is relying more and more on sensationalism and theatrics. The competition between the candidates has become a central focus of reporting, which has led to presidential campaigns being covered like sporting events. Major party candidates are portrayed increasingly less like potential leaders of the free world and more like athletes who are winning or losing a ballgame. The problem is not exit polls prematurely projecting a winner several hours before voting ends, but pre-election polls which do the same thing weeks before Election Day. Recommended for scholars interested in communication, political science, history, and sociology.

Tracking the effects of media content on the public is a difficult endeavor, and media effects vary on a subject-to-subject basis. To address this challenge, The Politics of Persuasion employs a multifaceted, mixed method approach to studying mass media and public attitudes. Anthony R. DiMaggio analyzes more than a dozen case studies covering US domestic economic policy and examines a wide range of theories of how bias operates in mass media with regard to coverage of these issues. While some research claims that journalists are overly negative and biased against government officials, some reveals that journalists favor citizens groups. Still other studies contend there is a liberal bias in the media, a progovernment bias, or a bias in favor of advertisers and business interests. Through his analysis, DiMaggio is the first to systematically examine all of these competing interpretations. He concludes that reporters tailor stories to corporate and government interests, but argues that the ability to "manufacture consent" from the public in favor of these elite views is far from guaranteed. According to DiMaggio, citizens often make use of their own personal experiences and prior attitudes to challenge official narratives.
