This work assesses the various meanings attached to calls for police reform in the public discourse on social media, providing readers with a greater appreciation of the assumptions, empirical claims, and rhetorical nuances that underpin the current dialogue about police policy. Drawing upon an intersectional theoretical and mixed-methods approach, the authors look at what it means to "defund" or "abolish" the police, as well as the definition of community policing. The death of George Floyd in 2020 resulted in national and international protests during which some members of the public began to demand "abolishing" or "defunding" the police, ideas previously put forth in academic arenas. However, these public protests were often presented in rhetorical ways that differed from the academic roots of the ideas. This book takes a deep look into what it means to "defund" or "abolish" the police, drawing upon academic origins of the concepts while at the same time examining how the public has used Twitter to define and discuss these ideas. The authors identify frameworks built around the concepts, discuss facts and perspectives that have contributed to these ideas, and explain how quantitative methods can be used to illustrate the most prominent frames. This book incorporates both quantitative and qualitative means of research in an examination of Twitter and brings clarity to the conversation surrounding the "abolish the police", "defund the police", and "community policing" concepts. It is suitable for undergraduate to graduate-level college courses in criminology, sociology, policing, race in America, communication, social media, and research methods.

This study examines tweet content from key periods of the uprisings in Egypt and Syria of 2011 and 2012, generally known as the “Arab Spring”. Some authors and the mainstream media have suggested that these uprisings were significantly influenced and organised by Twitter and subsequently referred to them as “Twitter Revolution”. Other authors have strongly opposed this idea and attributed it to self-deception in the light of marvellous inventions of the Western World. They have suggested Twitter was predominantly used as an information-sharing network. In an effort to contribute data to this debate, this study analyses tweet content from three different observation periods; two tweet datasets were collected from other academics and a third one was crawled from the Twitter API; this process made use of the crawling tool cURL and the database software mongoDB. The combined tweet dataset contained about 1.9 million tweets out of which a sample of 1945 tweets was drawn. This sample was then evaluated in a quantitative content analysis according to a coding manual. These codes were entered into the statistical analysis software SPSS, in which they were also processed.

The World Health Organization defines health as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”, and its constitution also asserts that health for all people is “dependent on the fullest co-operation of individuals and States”. The ongoing pandemic has highlighted the power of both healthy and unhealthy information, so while healthcare and public health services have depended upon timely and accurate data and continually updated knowledge, social media has shown how unhealthy misinformation can be spread and amplified, reinforcing existing prejudices, conspiracy theories and political biases. This book presents the proceedings of MedInfo 2021, the 18th World Congress of Medical and Health Informatics, held as a virtual event from 2-4 October 2021, with pre-recorded presentations for all accepted submissions. The theme of the conference was One World, One Health – Global Partnership for Digital Innovation and submissions were requested under 5 themes: information and knowledge management; quality, safety and outcomes; health data science; human, organizational and social aspects; and global health informatics. The Programme Committee received 352 submissions from 41 countries across all IMIA regions, and 147 full papers, 60 student papers and 79 posters were accepted for presentation after review and are included in these proceedings. Providing an overview of current work in the field over a wide range of disciplines, the book will be of interest to all those whose work involves some aspect of medical or health informatics.
