Title in Portuguese
Efeitos das conexões sociais nos processos de agenda-setting interpessoal
Keywords in Portuguese
agenda-setting
análise de redes sociais
Twitter
Abstract in Portuguese
Propomos o uso da análise de redes sociais para entender efeitos de agenda-setting. Para tanto, recuperamos a evolução dos estudos sobre a teoria da agenda-setting, desde as aplicações relacionadas à mídia tradicional até os estudos contemporâneos sobre mídias sociais. Em seguida, apresentamos o conceito de agenda-setting interpessoal e descrevemos métodos da análise de redes sociais para investigação desse conceito. A operacionalização empírica da proposta foi feita pela comparação de dois tipos de redes: 1) um grupo de indivíduos que publicou mensagens no Twitter sobre um tópico transmitido na TV nacional e 2) um grupo de indivíduos que publicou mensagens no Twitter sobre um tema que não fez parte da mídia broadcast. Nosso objetivo foi investigar as diferenças entre as redes de indivíduos que experimentaram efeitos de agenda-setting advindos da mídia de massa e indivíduos que experimentaram efeitos de agenda-setting interpessoal. Nossos resultados ainda são preliminares, mas indicam diferenças estruturais entre os grupos e evidências de que indivíduos mais centrais são impactados antecipadamente por mensagens transmitidas interpessoalmente.

Abstract in English
We propose the use of social network analysis to understand agenda-setting effects. To achive that purpose, we recover the evolution of studies on agenda-setting theory, from applications related to traditional media to contemporary studies on social media. Next, we present the concept of interpersonal agenda-setting and describe methods of social network analysis to investigate this concept. The empirical operationalization of the proposal was made by comparing two types of networks: 1) a group of individuals that tweeted about a topic broadcasted on national TV and 2) a group of individuals that tweeted about a non-mainstream topic. We aim to investigate differences between networks of individuals that experienced mass media agenda-setting effects and individuals that experienced interpersonal agenda-setting effects. Our results are still preliminary but indicate structural differences between the groups and also indicate evidence that more central individuals are impacted in advance by interpersonally transmitted messages.
