“…its direct and indirect contacts) represents an individual access which can be measured by the network constraint developed by Burt et al (1998), Burt (2008) and Burt and Merluzzi (2016). The first-type of constraint, network constraint is the most widespread measure in the literature, and is at the core of many works such as Aarstad (2014), Bizzi (2013), Buskens and van de Rijt (2008), Bruggeman et al (2003), Chung et al (2009), Chunlei et al (2014), Figueiredo et al (2015), Frankort (2008), Ho et al (2006), Kalish and Robins (2006), Kleinbaum and Stuart (2014), Li et al (2017), Mascia and Cicchetti (2011), Rost (2011) and Tortoriello (2015). Ucinet and Pajek software is used frequently to compute network constraint scores.…”

Social capital theory generally analyses network structures by focusing on the connections between players. However, it has been suggested by several authors that the absence of relations in a network or ‘structural holes’ is meaningful. The aim of our paper is to provide a global survey and appraisal of the academic research on structural holes and discuss its main measurements. We adopt a bibliometric approach and identify a typology of practices, developments, and issues related to structural holes. We highlight a strand of work on operationalization of structural holes, and discuss the various measures they propose. We provide numerical examples emphasizing the respective advantages and limitations of the studied measures. Based on our results, we propose a guide to using existing measures of structural holes according to the type (simple or complex) of network.

“…We then explored the role of individuals' network centrality, measured by the average friend number in the observation period (Jackson 2008), in the relationship between emotions and article cascades. Empirical evidence suggests that users' network centrality can affect the decisions of whether to share online content with different characteristic (Figueiredo et al 2015) and lead to larger information cascades (Banerjee et al 2013). Individuals with greater network centrality often have higher social status and exert increased social influence in adoption decisions (Hu and Van den Bulte 2014, Huang et al 2020).…”

Social media-transmitted online information, particularly content that is emotionally charged, shapes our thoughts and actions. In this study, we incorporate social network theories and analyses to investigate how emotions shape online content diffusion, using a computational approach. We rigorously quantify and characterize the structural properties of diffusion cascades, in which more than six million unique individuals transmitted 387,486 articles in a massive-scale online social network, WeChat. We detected the degree of eight discrete emotions (i.e., surprise, joy, anticipation, love, anxiety, sadness, anger, and disgust) embedded in these articles, using a newly generated domain-specific and up-to-date emotion lexicon. We found that articles with a higher degree of anxiety and love reached a larger number of individuals and diffused more deeply, broadly, and virally, whereas sadness had the opposite effect. Age and network degree of the individuals who transmitted an article and, in particular, the social ties between senders and receivers, significantly mediated how emotions affect article diffusion. These findings offer valuable insight into how emotions facilitate or hinder information spread through social networks and how people receive and transmit online content that induces various emotions.

“…Os indivíduos que apresentam elevado grau de contato na rede social, ou seja, relacionam-se intensamente com os demais membros da rede, ocupam posições mais centrais (Figueiredo, Chen, & Azevedo, 2015). Essas pessoas estão em vantagem em relação aos membros mais periféricos, pois o elevado nível de relacionamento na rede permite que seus colegas de trabalho estejam familiarizados com suas ideias e cientes dos seus pontos de vista.…”

“…Além disso, funcionários com elevado grau de relacionamento no trabalho possuem acesso direto aos recursos e demonstram certa independência (Figueiredo et al, 2015). Segundo Perry-Smith e Mannucci (2015), a independência em relação aos colegas de trabalho está relacionada com a percepção de liberdade.…”

Resumo A adequação indivíduo-organização refere-se à congruência dos valores individuais do funcionário aos valores organizacionais. Essa adequação é explorada em diversos resultados individuais e organizacionais, tais como: desempenho, comprometimento, motivação, etc. Embora vários fatores tenham sido identificados como responsáveis por essa adequação, poucos estudos brasileiros exploraram quantitativamente o papel das redes sociais dentro das empresas. Esses relacionamentos construídos e mantidos dentro da organização são identificados pelos padrões de comunicação e interação entre os indivíduos, e podem interferir no nível de adequação indivíduo-organização. O objetivo desta pesquisa é compreender como as características das redes sociais, tais como grau de relacionamento, proximidade entre os atores e nível de intermediação, podem influenciar o nível de adequação indivíduo-organização. Realizou-se um survey com 116 funcionários de micro e pequenas empresas do setor de serviços. Os resultados da análise Partial Least Squares (PLS) indicam que o grau de relacionamento entre os funcionários influencia o nível de adequação indivíduo-organização. Ou seja, quanto mais o funcionário interage com seus colegas de trabalho, maior a probabilidade de adequação dos valores do indivíduo com os da organização.
