The importance of social media as a way to monitor an electoral campaign is well established. Day-by-day, hour-by-hour evaluation of the evolution of online ideas and opinion allows observers and scholars to monitor trends and momentum in public opinion well before traditional polls. However, there are difficulties in recording and analyzing often brief, unverified comments while the unequal age, gender, social and racial representation among social media users can produce inaccurate forecasts of final polls. Reviewing the different techniques employed using social media to nowcast and forecast elections, this book assesses its achievements and limitations while presenting a new technique of "sentiment analysis" to improve upon them. The authors carry out a meta-analysis of the existing literature to show the conditions under which social media-based electoral forecasts prove most accurate while new case studies from France, the United States and Italy demonstrate how much more accurate "sentiment analysis" can prove.

Elections are a fundamental element of democracy, since elected governments reflect voter preferences. At the same time, it is inevitable that policies pursued by any government closely resemble the preferences of some citizens, while alienating others who hold different views. Previous works have examined how institutional settings facilitate or hinder policy proximity between citizens and governments. Building on their findings, the book explores a series of "so what" questions: how and to what extent does the distance between individual and government positions affect citizens'' propensity to vote, protest, believe in democracy, and even feel satisfied with their lives?

Using cross-national public opinion data, this book is an original scholarly research which develops theoretically grounded hypotheses to test the effect of citizen-government proximity on three dependent variables. After introducing the data (both public opinion surveys and country-level statistics) and the methodology to be used in subsequent chapters, one chapter each is devoted to how proximity or the absence thereof affects political participation, satisfaction with democracy, and happiness. Differences in political attitudes and behavior between electoral winners and losers, and ideological moderates and radicals, are also discussed in depth.

The SAGE Handbook of Research Methods in Political Science and International Relations offers a comprehensive overview of research processes in social science — from the ideation and design of research projects, through the construction of theoretical arguments, to conceptualization, measurement, & data collection, and quantitative & qualitative empirical analysis — exposited through 65 major new contributions from leading international methodologists. 

Each chapter surveys, builds upon, and extends the modern state of the art in its area. Following through its six-part organization, undergraduate and graduate students, researchers and practicing academics will be guided through the design, methods, and analysis of issues in Political Science and International Relations:

Part One: Formulating Good Research Questions & Designing Good Research Projects

Part Two: Methods of Theoretical Argumentation

Part Three: Conceptualization & Measurement

Part Four: Large-Scale Data Collection & Representation Methods

Part Five: Quantitative-Empirical Methods

Part Six: Qualitative & "Mixed" Methods

This book investigates the ideological conditions inducing political actors to highlight corruption issues through valence campaigns. Using case studies and comparative analyses of party programmes, legislatives speeches and social media data, the author demonstrates that the more parties and/or candidates present a similar policy programme, the more they rely on valence campaigns. In other words, as the ideologies of parties have become increasingly similar over recent decades, the content of political competition has substantially shifted from policy to non-policy factors, such as corruption issues. These dynamics, and the ideological considerations underpinning them, also provide a novel perspective on recent phenomena in contemporary democracies, such as the growth of negative campaigning, as well as populist strategies based on anti-elite rhetoric. The book will appeal to students and scholars interested in political corruption, valence politics, populism and electoral campaigning.

Due miliardi e mezzo di utenti internet, oltre un miliardo di account Facebook, 550 milioni di profili Twitter. Che parlano, discutono, si confrontano sui temi più svariati. Un flusso in continuo divenire di informazioni che dà sostanza ogni giorno al mondo dei Big Data. Ma come si analizza concretamente il “sentiment” della Rete? Quali sono i pregi e i limiti dei diversi metodi esistenti? E a quali domande possiamo dare una risposta?

Dopo aver presentato le varie tecniche di analisi testuale applicate ai social media, questo libro discute di come l’informazione presente in Rete sia in grado di aiutarci a meglio comprendere il presente e a fare previsioni sul futuro riguardo a una molteplicità di fenomeni sociali, che spaziano dall’andamento dei mercati finanziari, alla diffusione di malattie, alle rivolte e ai sommovimenti popolari fino ai risultati dei talent show, prima di concentrarsi su due casi specifici: l’andamento della felicità degli italiani giorno per giorno, e i risultati delle campagne elettorali in Francia, Stati Uniti e Italia tra il 2012 e il 2013.
