The focus of Software for Dependable Systems is a set of fundamental principles that underlie software system dependability and that suggest a different approach to the development and assessment of dependable software.Unfortunately, it is difficult to assess the dependability of software. The field of software engineering suffers from a pervasive lack of evidence about the incidence and severity of software failures; about the dependability of existing software systems; about the efficacy of existing and proposed development methods; about the benefits of certification schemes; and so on. There are many anecdotal reports, which—although often useful for indicating areas of concern or highlighting promising avenues of research—do little to establish a sound and complete basis for making policy decisions regarding dependability. The committee regards claims of extraordinary dependability that are sometimes made on this basis for the most critical of systems as unsubstantiated, and perhaps irresponsible. This difficulty regarding the lack of evidence for system dependability leads to two conclusions: (1) that better evidence is needed, so that approaches aimed at improving the dependability of software can be objectively assessed, and (2) that, for now, the pursuit of dependability in software systems should focus on the construction and evaluation of evidence.The committee also recognized the importance of adopting the practices that are already known and used by the best developers; this report gives a sample of such practices. Some of these (such as systematic configuration management and automated regression testing) are relatively easy to adopt; others (such as constructing hazard analyses and threat models, exploiting formal notations when appropriate, and applying static analysis to code) will require new training for many developers. However valuable, though, these practices are in themselves no silver bullet, and new techniques and methods will be required in order to build future software systems to the level of dependability that will be required.

A revolutionary concept-based approach to thinking about, designing, and interacting with softwareAs our dependence on technology increases, the design of software matters more than ever before. Why then is so much software flawed? Why hasn’t there been a systematic and scalable way to create software that is easy to use, robust, and secure?Examining these issues in depth, The Essence of Software introduces a theory of software design that gives new answers to old questions. Daniel Jackson explains that a software system should be viewed as a collection of interacting concepts, breaking the functionality into manageable parts and providing a new framework for thinking about design. Through this radical and original perspective, Jackson lays out a practical and coherent path, accessible to anyone—from strategist and marketer to UX designer, architect, or programmer—for making software that is empowering, dependable, and a delight to use.Jackson explores every aspect of concepts—what they are and aren’t, how to identify them, how to define them, and more—and offers prescriptive principles and practical tips that can be applied cost-effectively in a wide range of domains. He applies these ideas to contemporary software designs, drawing examples from leading software manufacturers such as Adobe, Apple, Dropbox, Facebook, Google, Microsoft, Twitter, and others. Jackson shows how concepts let designers preserve and reuse design knowledge, rather than starting from scratch in every project.An argument against the status quo and a guide to improvement for both working designers and novices to the field, The Essence of Software brings a fresh approach to software and its creation.

The Routledge Handbook of Political Campaigning provides an essential, global, and timely overview of current realities, as well as anticipating the trajectory and evolution of campaigning in the coming years.

Offering a comprehensive analysis, the handbook is structured into seven thematic sections, including the campaign environment; rhetoric and persuasion; campaign strategies; campaign tactics and platform affordances; news and journalism; citizens and voters; and civil society. The chapters within each section reflect on the latest societal, technological, and cultural developments and their impact on campaigning, on democratic culture within societies, and on the roles that campaigns might play in both facilitating and impeding political engagement. Key trends and innovations are examined alongside case studies and examples from a range of nations and political contexts. Issues around trust and representation are further reflected in a focus on the wider campaigning environment and the rise in importance of grassroots and pressure groups, social movements, and movements that coalesce within digital environments.

The Routledge Handbook of Political Campaigning is an essential resource for scholars, students, and practitioners in political communication, media and communication, elections and voting behavior, digital media, journalism, social movements, strategic communication, social media, and more broadly to democracy, sociology, and public policy.

Technological, cultural and economic forces are transforming political communication, posing challenges and opportunities for politicians and media organisations, while at the same time many governments and civil society express concerns about the extent and nature of political empowerment and civic engagement.

This book offers an international perspective on current thinking and practice about civic and audience empowerment, focusing on the ways and means through which media can empower or dis-empower citizens as audiences. It features theoretical and empirical chapters that draw specific attention to a reappraisal of the theories, methods and issues that inform our understanding of citizens and audiences in contemporary politics. The authors address the following questions:

With examples from the UK, USA, Holland, France, Germany, The Middle East, South Africa and Mexico, this innovative volume will be of interest to students and scholars of political science, marketing, journalism, cultural studies, public relations, media and international relations.

The London 2012 Paralympic Games - the biggest, most accessible and best-attended games in the Paralympics'' 64-year history - came with an explicit aim to "transform the perception of disabled people in society," and use sport to contribute to "a better world for all people with a disability." This social agenda offered the potential to re-frame disability; to symbolically challenge "ableist" ideology and to offer a reinvention of the (dis)abled body and a redefinition of the possible. This edited collection investigates what has and is happening in relation to these ambitions. The book is structured around three key questions: 1. What were the predominant mediated narratives surrounding the Paralympics, and what are the associated meanings attached to them? 2. How were the Paralympics experienced by media audiences (both disabled and non-disabled)? 3. To what extent did the 2012 Paralympics inspire social change? Each section of this book is interspersed with authentic "voices" from outside academia: broadcasters, athletes and disabled schoolchildren.
