Summary: This paper explores the definitions and implementations of extremism in different opinion dynamics models, and suggests that Bayesian inspired opinion models can provide a perspective to better address the differences, thereby tackling the problem of extremism more effectively.

Summary: Inspired by partisan competitions and contentious elections in democratic countries, this study numerically explores the impact of campaign strategies and related factors on the opinion of an electorate. Short-term high-impact campaigns are found to be effective in electorates with conformist agents, while long-term campaigns targeting local politics are more effective in electorates with both conformist and contrarian agents and varying levels of dominance due to local factors.

Summary: This study presents evidence from two national surveys indicating that moderate Democratic candidates have an electoral advantage over more extreme candidates in elections against Donald Trump. However, the high support for Bernie Sanders is due to an implausibly large increase in intended turnout among young voters.

Summary: This study develops a Downsian model of electoral competition and reveals the phenomena of platform divergence and inefficiency in campaign spending during the process of candidates using platforms and campaign spending to gain voter support.

Summary: This study compares mass media debates on extreme right and Islamist terrorist attacks and highlights the impact of ideology on political reactions and framing of key security threats. The results demonstrate the favorable conditions for the far right in both types of attacks, with political elites playing a central role in disseminating far-right frames. Meanwhile, victims and ethnic or religious minorities have little voice in public debates.

Summary: Core values, defined as abstract beliefs about government and society, play a crucial role in enabling citizens to reason about politics. However, research shows that electoral campaigns have limited effect on activating citizens' core values.

Summary: This paper introduces four mathematical measures for polarisation in society, including min-max flow, spectral radius, Kullback-Leibler divergence, and Hellinger distance. Results from opinion dynamics simulations show that these measures provide insight into different aspects of polarisation and allow real-time monitoring of polarisation indicators in social networks.

Summary: This study examines the evolution of Argentina's political landscape during the 2015 and 2019 presidential elections using Twitter data, building a semantic network to detect societal topics. By assigning dynamic topic vectors to users, it reveals similarities and differences among groups of supporters of different candidates. The method can capture the reshaping of political opinions and the inversion of election results between the two rounds in 2015.

Summary: The study introduces an active model to demonstrate the macroscopic development of opinion evolution, revealing the difference between people's voting results and collective opinions, and how this difference narrows with the stabilization of opinion evolution.

Summary: By using two models of opinion dynamics, this study explores the impact of the change of disorder from annealed to quenched on phase transitions in networks. The results reveal that such a change of disorder eliminates all discontinuous phase transitions and broadens ordered phases. Moreover, the annealed and quenched types of disorder lead to distinct phase diagrams on networks.

Summary: In social networks, the influence of advertisement opinion leaders plays a crucial role in shaping followers' opinions. The study reveals that advertisement influence has a dual effect on opinion evolution, and the probability of information transmission by opinion leaders significantly impacts collective opinion evolution.

Summary: This study argues that political parties can avoid blame and even gain electoral advantages by effectively responding to terrorism and utilizing their local presence. The Justice and Development Party (AKP) in Turkey is highlighted as a successful example, as they maintained their national incumbency and even strengthened their dominance in the political system despite growing security threats.

Summary: This paper estimates the persuasive effect of newspaper presidential endorsements on its readers over five elections (1960-1980), a period when the vast majority of newspaper endorsements were for the Republican candidate. The study finds that newspaper endorsements caused a large, significant change in readers' preferred candidate and Republican endorsements, despite being more common, were at least as effective as Democratic endorsements.

Summary: In this study, we constructed a two-layer multiplex network for the coupled spread of disease and conflicting opinions. We found that opinion dynamics can influence disease transmission, lengthening the duration of holding an opinion may suppress disease transmission, and increasing cross-layer or intra-layer correlations of node degrees may reduce the number of individuals infected with the disease.
