Comparing political communication across time and space : new studies in an emerging field
\"This volume addresses the challenges that political communication is facing today from a comparative perspective, using principles and methods of comparison both across space (cross-national) and across time (longitudinal), thereby advancing the understanding of global trends and cultural differences. It covers a wide range of countries and cultures from advanced Western democracies and beyond. The research tools employed include quantitative and qualitative content analyses, comparative case studies, document analysis, opinion surveys, elite interviews and a combination of various methods. Employing different research strategies and theoretical approaches, this book sheds new light on key concepts in the literature on comparative political communication research, such as professionalization, personalization and globalization. It also investigates processes of change and transformation, such as negativization of campaigns, internationalization of campaign coverage, professionalization of government communication, democratization, commercialization of the media and transnationalization of national public spheres. \"-- Provided by publisher.

Research on the Role of Computer Image Technology in Visual Communication Design
Computer image came into being at the end of 1980s, and it has experienced more than 30 years of development. Image processing technology has been widely used and has become modern applied science. Computer technology is playing an increasingly important role in people’s daily life. The use of computer technology is becoming more and more extensive along with the construction and development of information society nowadays. People’s daily life and work are inseparable. Computer graphics has also been fully valued, which greatly improves the overall effect and level of visual communication design. Graphic image processing technology is also widely used in today’s society, the works designed with it can bring great impact on people’s vision. This paper analyzes the meaning of computer graphics and image technology and visual communication design, and on this basis, expounds the significance of computer graphics and image technology on the realization of visual communication design elements, hoping that the results can bring some help to the relevant leading city [1].

On the ‘grand narrative’ of media and mass communication theory and research: a review
This paper offers a genealogy of the field of mass media and communication theory and research, with the purpose of distilling a grand narrative of media studies and communication science. Such a ‘story of stories’ is articulated with recurring concerns over the categories and taxonomies of the communication process, the rapid development and penetration of new information and communication technologies, and attempts by scholars around the world to respond to our increasingly complex and convergent media environment. In conclusion, an argument is developed for a vital, creative, and public way forward for the field.

Communication and midterm elections : media, message, and mobilization
\"This book offers a comprehensive examination of contemporary US midterm elections through the lens of communications and media coverage. Using a wide variety of methods, this contributed volume covers the challenges unique to midterm elections. In the US, midterm elections do not receive the same amount of media attention and voter participation as presidential elections, yet their outcomes often have significant consequences. This edited collection closely examines 2014 midterm election trends in media, messaging, and mobilization. The 2014 midterm election yielded several important trends, headlines, and milestones: Democrats suffered significant and humbling defeats, historically low turnout propelled a sweeping Republican wave, billions of dollars were spent airing millions of ads, unprecedented amounts of 'dark money' linked to outside groups was used to buy television advertisements, working-class white voters continued their decades-long defection from the Democratic Party, and Republicans devoted substantial time and resources to catch up with Democrats in the use of digital and social media. Communication and Midterm Elections includes top scholars from leading research institutions using various research methodologies to generate new understandings--both theoretical and practical--for students, researchers, journalists, and practitioners\"-- Provided by publisher.

The process and domain of intergroup communication: Mapping the field
This article presents an integrative model mapping the field of intergroup communication. Building from Lasswell’s (1948) model of communication, our map discusses how communication about and between groups can be understood by separating Lasswell’s concepts (sender/receiver, message, channel, and effect). We present the articles in the current special issue as examples fitting within the map and illustrate how the map suggests some interesting extensions of this work.

Mediatization of politics : understanding the transformation of western democracies
\"The first book-long analysis of the 'mediatization of politics', this volume aims to understand the transformations of the relationship between media and politics in recent decades, and explores how growing media autonomy, journalistic framing, media populism and new media technologies affect democratic processes. As politics becomes increasingly mediatized, the role of the media becomes more important in political processes, overlaying and subsuming political logic. This affects not only the presentational aspects of politics but, it is feared, also policymaking processes. This may in turn have far-reaching implications as to how well democracy works. Against this background, Mediatization of Politics brings together state-of-the-art chapters written by leading scholars in the field of political communication. It synthesizes relevant concepts and arguments, identifies core components of the mediatization paradigm, and sets the agenda for subsequent work on the changing relationship between media and politics in general, and on the mediatization of politics in particular\"-- Provided by publisher.

CASE STUDY ON THE EFFICIENCY OF COMMUNICATION AT THE WORKPLACE IN AN ORGANIZATION
The paper present a case study which aims to improve the efficiency of communication relations, between employees and managers within an organization, namely within the Joyson company.The study is based on the interpretation of the results of a questionnaire that includes 14 relevant questions regarding the existing communication relationships within the organization where the questionnaire was implemented, to which questions all employees answered. The results of the study can be considered eloquent not only for the organization in which the questionnaire was implemented but also for other organizations facing similar communication problems for the solution of which they could use a questionnaire to identify and remove existing communication barriers between management organization and employees, a fact that would determine the efficiency of the communication climate primarily but also of the organizational climate in general.

Prime Ministers and rhetorical governance
\"It is a well-known fact that Prime ministers are fond of talking, in fact at times it seems impossible to get them to do anything else. The reason for this constant talking is that Prime Ministers are all too aware of the importance of frequently talking to and communicating with the electorate. Political rhetoric has a central function that goes far beyond the need to rouse people at election time or in times of great crisis but rather persuasive political talk by prime ministers is central to the practice of modern government itself.This book argues that there are institutionalised patterns in the speeches that prime ministers give. Like an old-style jukebox, there are only a certain number of records in the prime ministerial machine. Inevitably, each prime minister will play the same songs in the same order as their predecessor. This repetitive rhetoric has an impact not just on the minds of voters, but also on day-to-day governance in Westminster system democracies\"-- Provided by publisher.

PETLFC: Parallel ensemble transfer learning based framework for COVID-19 differentiation and prediction using deep convolutional neural network models
Despite a worldwide research involvement in the global COVID-19 pandemic, the research community is still struggling to develop reliable and faster prediction mechanisms for this infectious disease which is distinct from other respiratory diseases. The commonly used clinical RT-PCR test is not widely available in areas with limited testing facilities, and it performs and responds slowly. Using digital chest X-Ray images and CT scan images, recently a number of works are proposed using deep transfer learning and ensemble of these deep models as base classifiers. Though ensemble approaches exhibit better accuracy, they are computational intensive and have slower prediction time. Therefore, to handle computational-intensiveness and to accelerate prediction time without compromising accuracy, a Parallel Ensemble Transfer Learning based Framework for COVID (PETLFC) is proposed for the underlying multi-class classification problem. Three pre-trained convolutional neural network models (VGG16, ResNet18, and DenseNet121) were fine tuned to act as base models for the proposed parallelized bagging-based ensemble to predict COVID-19. The data parallel model is implemented on PARAM SHAVAK HPC system using MPI programming and a dataset of 21,165 chest X-Ray images (10,192 normal, 1345 pneumonia, 3616 COVID-19, and 6012 lung opacity). The results are compared with some state-of-the-art sequential ensemble approaches where the proposed PETLFC was observed to exhibit superior performance.
Highlights
• This work proposes a parallel ensemble transfer learning based deep CNN framework for COVID-19 prediction from chest X-Rays.
• The deep CNN models which are tuned using transfer learning are: DenseNet-121, VGG-16 and ResNet18. They act as base classifiers for the proposed parallelized bagging-based ensemble.
• The underlying problem is formulated using data parallel model and as a multi-class classification problem to differentiate COVID-19 from other similar pulmonary diseases. This enables the model to predict COVID-19 in lesser time due to parallelism, with equal accuracy with state-of-the-art sequential bagging-based ensemble methods.
• An in-depth evaluation of the system is carried out considering standard performance metrics like accuracy, precision, recall and F1-score. The parallel system is tested using standard parallel performance metrics like speedup and efficiency.
