Historically, or so we would like to believe, the story of everyday life for many people included regular, definitive moments of news consumption. Journalism, in fact, was distributed around these routines: papers were delivered before breakfast, the evening news on TV buttressed the transition from dinner to prime time programming, and radio updates were centred around commuting patterns. These habits were organized not just around specific times but occurred in specific places, following a predictable pattern. However, the past few decades have witnessed tremendous changes in the ways we can consume journalism and engage with information – from tablets, to smartphones, online, and so forth – and the different places and moments of news consumption have multiplied as a result, to the point where news is increasingly mobile and instantaneous. It is personalized, localized and available on-demand. Day-by-day, month-by-month, year-by-year, technology moves forward, impacting more than just the ways in which we get news. These fundamental shifts change what news ‘is’. This book expands our understanding of contemporary news audiences and explores how the different places and spaces of news consumption change both our experiences of journalism and the roles it plays in our everyday lives. This book was originally published as a special issue of Journalism Studies.

There is no doubt, journalism faces challenging times. Since the turn of the millennium, the financial health of the news industry is failing, mainstream audiences are on the decline, and professional authority, credibility and autonomy are eroding. The outlook is bleak and it’s understandable that many are pessimistic. But this book argues that we have to rethink journalism fundamentally.Rather than just focus on the symptoms of the ‘crisis of journalism’, this collection tries to understand the structural transformation journalism is undergoing. It explores how the news media attempts to combat decreasing levels of trust, how emerging forms of news affect the established journalistic field, and how participatory culture creates new dialogues between journalists and audiences. Crucially, it does not treat these developments as distinct transformations. Instead, it considers how their interrelation accounts for both the tribulations of the news media and the need for contemporary journalism to redefine itself.

Algebraic geometry is a central subfield of mathematics in which the study of cycles is an important theme. Alexander Grothendieck taught that algebraic cycles should be considered from a motivic point of view and in recent years this topic has spurred a lot of activity. This 2007 book is one of two volumes that provide a self-contained account of the subject. Together, the two books contain twenty-two contributions from leading figures in the field which survey the key research strands and present interesting new results. Topics discussed include: the study of algebraic cycles using Abel-Jacobi/regulator maps and normal functions; motives (Voevodsky's triangulated category of mixed motives, finite-dimensional motives); the conjectures of Bloch-Beilinson and Murre on filtrations on Chow groups and Bloch's conjecture. Researchers and students in complex algebraic geometry and arithmetic geometry will find much of interest here.

This up-to-date introduction to Griffiths' theory of period maps and period domains focusses on algebraic, group-theoretic and differential geometric aspects. Starting with an explanation of Griffiths' basic theory, the authors go on to introduce spectral sequences and Koszul complexes that are used to derive results about cycles on higher-dimensional algebraic varieties such as the Noether-Lefschetz theorem and Nori's theorem. They explain differential geometric methods, leading up to proofs of Arakelov-type theorems, the theorem of the fixed part and the rigidity theorem. They also use Higgs bundles and harmonic maps to prove the striking result that not all compact quotients of period domains are Kähler. This thoroughly revised second edition includes a new third part covering important recent developments, in which the group-theoretic approach to Hodge structures is explained, leading to Mumford-Tate groups and their associated domains, the Mumford-Tate varieties and generalizations of Shimura varieties.

It’s easy to make a rhetorical case for the value of journalism. Because, it is a necessary precondition for democracy; it speaks to the people and for the people; it informs citizens and enables them to make rational decisions; it functions as their watchdog on government and other powers that be.But does rehashing such familiar rationales bring journalism studies forward? Does it contribute to ongoing discussions surrounding journalism’s viability going forth? For all their seeming self-evidence, this book considers what bearing these old platitudes have in the new digital era. It asks whether such hopeful talk really reflects the concrete roles journalism now performs for people in their everyday lives. In essence, it poses questions that strike at the core of the idea of journalism itself. Is there a singular journalism that has one well-defined role in society? Is its public mandate as strong as we think?The internationally-renowned scholars comprising the collection address these recurring concerns that have long-defined the profession and which journalism faces even more acutely today. By discussing what journalism was, is, and (possibly) will be, this book highlights key contemporary areas of debate and tackles on-going anxieties about its future.

The first edition of "Compact Complex Surfaces" was published in 1984 and has become one of the most important books on the subject. In this second enlarged edition the major developments of the last 20 years have been incorporated. The Enriques-Kodaira classification is carried out in the spirit of Mori theory and many new developments have been added, including new analytic tools as well as new algebraic methods such as the theorems of Bogomolov and Reider and their applications. A new section is devoted to the stunning results achieved by the introduction of Donaldson and Seiberg-Witten invariants.

In the 19 years which passed since the first edition was published, several important developments have taken place in the theory of surfaces.
