Generation Zombie: The new essential guide to why screens and devices are harming our children and what we can do about it
by Dr Charlotte Armitage'It is never too late to make changes and put things right. If we recognise the problem of device use, we can regain control of our families and allow our children to grow up as they should.' Dr Charlotte ArmitageMany theories that form the bedrock of good parenting were created decades before devices even existed - they don't consider the significant impact on a child's psychological and physical development. The landscape of the early years has changed so quickly, yet parents and caregivers do not have access to the evidence-based, practical advice they need to manage this invasion of screens. They can see their children become addicted to devices, but don't know what to do. Generation Zombie will fill this knowledge gap.Through her clinical work as a psychotherapist, work with schools and as a duty of care psychologist, Dr Charlotte Armitage has witnessed the terrifying impact of screen time on her clients and their families. However, unlike other addictions, the harmful consequences of devices are not widely recognised. With the vital insights in her book - including practical tips and engaging case studies - her mission is hopeful and empowering; to enable parents to make a positive change. Away from devices, you will be amazed how quickly you notice children's behaviour change.

Generative AI and Cyberbullying
by Ravindra DasEver since the COVID-19 pandemic occurred in 2020, the world has transformed itself greatly. For example, not only is the near-99% remote workforce now a reality, but businesses today are taking incident response and disaster recovery much more seriously these days as well. But another area that has blossomed in the last couple of years has been that of Generative AI. It is actually a subfield of artificial intelligence, which has been around since the 1950s.But Gen AI (as it is also called) has been fueled by the technology of ChatGPT, which has been developed and created by OpenAI. Given the GPT4 algorithms Gen AI is powered by, an end user can merely type in, or even speak into the platform a query, and an output that is specific to that query will be automatically generated. The answer (or "output") can be given as a text, video, image, or even an audio file.The scalability and diversity of Gen AI has allowed it to be used in a myriad of industries and applications. But although it has been primarily designed to serve the greater good, it can also be used for very nefarious purposes, such as online harassment and Cyberbullying.In this particular book, we actually take the good side of Gen AI and provide an overview as to how it can be used to help combat Cyberbullying. This book is broken down into the following topics: What Cyberbullying is all about How Gen AI can be used to combat Cyberbullying An overview into Gen AI Advanced topics into Gen AI Conclusions

Geneses: A Comparative Study of the Historiographies of the Rise of Christianity, Rabbinic Judaism, and Islam
by John TolanWhat is a religion? How do we discern the boundaries between religions, or religious communities? When does Judaism become Judaism, Christianity become Christianity, Islam become Islam? Scholars have increasingly called into question the standard narratives created by the various orthodoxies, narratives of steadfastness and consistency, of long and courageous maintenance of true doctrine and right practice over the centuries, in the face of opposition (and at times persecution) at the hands of infidels or heretics. The 11 chapters in this book, Geneses: A Comparative Study of the Historiographies of the Rise of Christianity, Rabbinic Judaism and Islam, written by an international group of specialists the languages, religions, laws and cultures of early Judaism, Christianity and Islam, tackle these questions through a comparative study of these narratives: their formation over time, and their use today. They explore three key aspects of the field: (1) the construction (and scholarly deconstruction) of the narratives of triumph (and defeat) of religions, (2) how legal imperatives are constructed from religious narratives and sacred texts, and (3) contemporary ramifications of these issues. In doing so, they tap into the significant body of research over the last 30 years, which has shown the fluidity and malleability of these religious traditions in relation to each other and to more traditional "pagan" and Zoroastrian religions and philosophical traditions. This book represents an important contribution to, and a valuable resource for, the burgeoning field of comparative history of the Abrahamic religions.

Genre Knowledge in Disciplinary Communication: Cognition/culture/power
by Carol Berkenkotter Thomas N. HuckinAlthough genre studies abound in literary criticism, researchers and scholars interested in the social contexts of literacy have recently become interested in the dynamic, rhetorical dimensions of speech genres. Within this burgeoning scholarly community, the authors are among the first researchers working within social science traditions to study genre from the perspective of the implicit knowledge of language users. Thus, this is the first sociocognitive study of genre using case-study, naturalistic research methods combined with the techniques of rhetorical and discourse analysis. The term "genre knowledge" refers to an individual's repertoire of situationally appropriate responses to recurrent situations -- from immediate encounters to distanced communication through the medium of print, and more recently, the electronic media. One way to study the textual character of disciplinary knowledge is to examine both the situated actions of writers, and the communicative systems in which disciplinary actors participate. These two perspectives are presented in this book. The authors' studies of disciplinary communication examine operations of systems as diverse as peer review in scientific publications and language in a first grade science classroom. The methods used include case study and ethnographic techniques, rhetorical and discourse analysis of changing features within large corpora and in the texts of individual writers. Through the use of these techniques, the authors engaged in both micro-level and macro-level analyses and developed a perspective which reflects both foci. From this perspective they propose that what micro-level studies of actors' situated actions frequently depict as individual processes, can also be interpreted -- from the macro-level -- as communicative acts within a discursive network or system. The research methods and the theoretical framework presented are designed to raise provocative questions for scholars, researchers, and teachers in a number of fields: linguists who teach and conduct research in ESP and LSP and are interested in methods for studying professional communication; scholars in the fields of communication, rhetoric, and sociology of science with an interest in the textual dynamics of scientific and scholarly communities; educational researchers interested in cognition in context; and composition scholars interested in writing in the disciplines.

Geomedia Studies: Spaces and Mobilities in Mediatized Worlds (Routledge Research in Cultural and Media Studies)
by Karin Fast André Jansson Johan Lindell Linda Ryan Bengtsson Mekonnen TesfahuneyThis book introduces and develops the concept of geomedia studies as the name of a particular subfield of communication geography. Despite the accelerating societal relevance of ‘geomedia’ technologies for the production of various spaces, mobilities, and power-relations, and the unquestionable emergence of a vibrant research field that deals with questions pertaining to such topics, the term geomedia studies remains surprisingly unestablished. By addressing imperative questions about the implications of geomedia technologies for organizations, social groups and individuals (e.g. businesses profiting from geo-surveillance, refugees or migrants moving across national borders, or artists claiming their rights to public space) the book also aims to contribute to ongoing academic and societal debates in our increasingly mediatized world.

George Alfred Townsend and Gathland: A Journalist and His Western Maryland Estate
by Dianne WiebeThe youngest correspondent to cover the Civil War and a pioneer in newspaper syndication, George Alfred Townsend came from modest circumstances. Using the pen name of GATH, he rose to fame and fortune after the war, and his career brought him into contact with sitting presidents and luminaries such as Mark Twain. Though almost forgotten today in the canon of Maryland authors, GATH left a lasting legacy of literature and a most unique monument. He created a lavish summer estate near Boonsboro, Maryland, named Gapland--now called Gathland. He also famously erected the War Correspondents Memorial Arch, a monument to fellow wartime journalists. Today, GATH's estate is preserved and interpreted by a state park and its museums. His commanding arch remains a bold reminder of the creative genius of George Alfred Townsend.
George Augustus Sala and the Nineteenth-Century Periodical Press: The Personal Style of a Public Writer
by Peter BlakeIn his study of the journalist George Augustus Sala, Peter Blake discusses the way Sala’s personal style, along with his innovations in form, influenced the New Journalism at the end of the nineteenth century. Blake places Sala at the centre of nineteenth-century newspapers and periodicals and examines his prolific contributions to newspapers and periodicals in the context of contemporary debates and issues surrounding his work. Sala’s journalistic style, Blake argues, was a product of the very different mediums in which he worked, whether it was the visual arts, bohemian journalism, novels, pornographic plays, or travel writing. Harkening back to a time when journalism and fiction were closely connected, Blake’s book not only expands our understanding of one of the more prominent and interesting journalists and personalities of the nineteenth century, but also sheds light on prominent nineteenth-century writers and artists such as Charles Dickens, Mathew Arnold, William Powell Frith, Henry Vizetelly, and Mary Elizabeth Braddon.
George Seldes’ War for the Public Good: Weaponising a Free Press (Palgrave Studies in the History of the Media)
by Helen FordhamThis book examines the idea of fake news through an analysis of the work of early to mid-twentieth century press critic George Seldes. By examining fake news - also known as propaganda and misinformation - from this period it becomes evident that it is a phenomenon that emerges in response to particular social, political and economic conditions. It is, therefore, not a new process but always a feature of the media ecosystem. Seldes’ work makes evident that contemporary anxieties about the role, function, future and credibility of journalism were expressed in the 1930s and 1940s. The same fears were circulated about the consequences of fake news and propaganda on democratic debate. The same concerns were also expressed about how technology extends the circulation of propaganda and fake news, and affects journalism practices. An analysis of Seldes’ media criticism of the fake news, lies and propaganda in daily newspapers in the 1930s and 1940s exposes the historical nature and impact of fake news on public debate, and affirms the critical role of journalists in exposing fake news.
George Washington's War: In Caricature and Print
by Kenneth BakerA Revolutionary War history told through eighteenth-century illustrations: &“Utterly absorbing&” (The Times, London). Americans are steeped in the history of the American Revolution, but often the fog of myth shrouds the reality. In these pages, the path to war is starkly documented by British caricatures of politicians and generals—for the most part favorable to the Colonists. For George III, Lord North, and Britain, the war was a disaster that need not have happened. The problems of coping with a country five thousand miles away with a tradition of representative government, a free press, and a spirit of independence were just too much. But they, together with Generals Howe, Burgoyne, Cornwallis, and others, were mercilessly lampooned. Washington, the hero, is spared, although there are surprising and dark elements to the American victory illustrated here. Using prints and caricatures from the period—some never before published—and drawing on his own experience in politics, Kenneth Baker provides vivid and memorable images that illustrate these extraordinary historical events.
