This book was released on 2012-02 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2005 in the subject English Language and Literature Studies - Linguistics, grade: 2,0, University of Rostock, language: English, abstract: Many articles one reads in a newspaper have an emotional impact on the addressee. This impact can involve the public in general or only a limited part of the readership. For instance a headline like One of these players will be axed (from News of the World, September 4, 2005) will probably not effect the whole British readership but only a part of it, namely those who are interested in soccer. They might be sad that players of their favourite team will be dismissed. (Ungerer in Niemeyer/Dirven 1995: 307) But how is it possible for a news story to cause emotions in the reader? In my term paper I am going to describe the system which is responsible for the emotional impact of news stories. Afterwards I will go on to give a short overview of the different kinds of emotions which can be evoked. My next section will take us to the main concern of this paper: the comparison of quality and popular papers regarding their emotional impact. I will analyse a news story from The Guardian which is one of the British quality papers. Then I will have a detailed look at a news story from the British popular paper News of the World which deals with the same issue. I will try to find out which of both the papers arouses more or greater emotions in the reader and what means they use to achieve that. What are the different ways in which emotions are approached in the two kinds of newspapers? In my conclusion I will evaluate the comparison and make an effort to answer the question asked before.

Download or read book News Framing Effects written by Sophie Lecheler and published by Routledge. This book was released on 2018-09-03 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: News Framing Effects is a guide to framing effects theory, one of the most prominent theories in media and communication science. Rooted in both psychology and sociology, framing effects theory describes the ability of news media to influence people’s attitudes and behaviors by subtle changes to how they report on an issue. The book gives expert commentary on this complex theoretical notion alongside practical instruction on how to apply it to research. The book’s structure mirrors the steps a scholar might take to design a framing study. The first chapter establishes a working definition of news framing effects theory. The following chapters focus on how to identify the independent variable (i.e., the "news frame") and the dependent variable (i.e., the "framing effect"). The book then considers the potential limits or enhancements of the proposed effects (i.e., the "moderators") and how framing effects might emerge (i.e., the "mediators"). Finally, it asks how strong these effects are likely to be. The final chapter considers news framing research in the light of a rapidly and fundamentally changing news and information market, in which technologies, platforms, and changing consumption patterns are forcing assumptions at the core of framing effects theory to be re-evaluated.

Download or read book News based Sentiment Indicators written by Chengyu Huang and published by International Monetary Fund. This book was released on 2019-12-06 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: We construct sentiment indices for 20 countries from 1980 to 2019. Relying on computational text analysis, we capture specific language like “fear”, “risk”, “hedging”, “opinion”, and, “crisis”, as well as “positive” and “negative” sentiments, in news articles from the Financial Times. We assess the performance of our sentiment indices as “news-based” early warning indicators (EWIs) for financial crises. We find that sentiment indices spike and/or trend up ahead of financial crises.

Download or read book Emotional written by Leonard Mlodinow and published by Pantheon. This book was released on 2022-01-11 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: We’ve all been told that thinking rationally is the key to success. But at the cutting edge of science, researchers are discovering that feeling is every bit as important as thinking. You make hundreds of decisions every day, from what to eat for breakfast to how you should invest, and not one of those decisions would be possible without emotion. It has long been said that thinking and feeling are separate and opposing forces in our behavior. But as Leonard Mlodinow, the best-selling author of Subliminal, tells us, extraordinary advances in psychology and neuroscience have proven that emotions are as critical to our well-being as thinking. How can you connect better with others? How can you make sense of your frustration, fear, and anxiety? What can you do to live a happier life? The answers lie in understanding your emotions. Journeying from the labs of pioneering scientists to real-world scenarios that have flirted with disaster, Mlodinow shows us how our emotions can help, why they sometimes hurt, and what we can learn in both instances. Using deep insights into our evolution and biology, Mlodinow gives us the tools to understand our emotions better and to maximize their benefits. Told with his characteristic clarity and fascinating stories, Emotional explores the new science of feelings and offers us an essential guide to making the most of one of nature’s greatest gifts.

Download or read book WikiLeaks written by Charlie Beckett and published by Polity. This book was released on 2012-02-13 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: WikiLeaks is the most challenging journalistic phenomenon to have emerged in the digital era. It has provoked anger and enthusiasm in equal measure, from across the political and journalistic spectrum. WikiLeaks poses a series of questions to the status quo in politics, journalism and to the ways we understand political communication. It has compromised the foreign policy operations of the most powerful state in the world, broken stories comparable to great historic scoops like the Pentagon Papers, and caused the mighty international news organizations to collaborate with this tiny editorial outfit. Yet it may also be on the verge of extinction. This is the first book to examine WikiLeaks fully and critically and its place in the contemporary news environment. The authors combine inside knowledge with the latest media research and analysis to argue that the significance of Wikileaks is that it is part of the shift in the nature of news to a network system that is contestable and unstable. Welcome to Wiki World and a new age of uncertainty.

Download or read book Economic News Sentiment and Behavior written by Juliane A. Lischka and published by Springer. This book was released on 2015-11-04 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the relations between objective, media-related, and social attitudinal as well as behavioral realities of private, expert, and corporate agents in the traditions of mass communication, journalism studies and behavioral economics. Results based on time series analyses for German data show that the news reports in a volatile manner on the economy and may influence its development through third-person effects. Bad economic news does not cause a decrease in private purchase intentions. Bad news may lead to a change in corporate decisions, such as advertising expenditures, because corporate decision makers may presume changes in consumer behavior through news.

Download or read book Media Sentiment and International Asset Prices written by Samuel P. Fraiberger and published by International Monetary Fund. This book was released on 2018-12-10 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: We assess the impact of media sentiment on international equity prices using more than 4.5 million Reuters articles published across the globe between 1991 and 2015. News sentiment robustly predicts daily returns in both advanced and emerging markets, even after controlling for known determinants of stock prices. But not all news-sentiment is alike. A local (country-specific) increase in news optimism (pessimism) predicts a small and transitory increase (decrease) in local returns. By contrast, changes in global news sentiment have a larger impact on equity returns around the world, which does not reverse in the short run. We also find evidence that news sentiment affects mainly foreign – rather than local – investors: although local news optimism attracts international equity flows for a few days, global news optimism generates a permanent foreign equity inflow. Our results confirm the value of media content in capturing investor sentiment.
