Resumo: | This study analyzes the network evolution, specifically that of the Brazilian film network. It examines two generative mechanisms that lie behind the network evolution: preferential attachment and fitness. The starting point is that preferential attachment and fitness may compete to shape the network evolution. We built a novel dataset with 974 Brazilian feature films released between 1995 and 2017 and used PAFit, a brand-new statistical method, to estimate the joint effects of preferential attachment and fitness on the evolution of the Brazilian film network. This study concludes that the network evolution is shaped by both preferential attachment and fitness. However, in the presence of fitness, the effects of preferential attachment on the network evolution become weaker. This means that the node ability to form ties in the Brazilian film network is mainly explained by its fitness. Besides, the preferential attachment assumes a sub-linear form. Costs, communication and managerial capabilities, and node age explain why nodes are unable to accumulate ties at rates proportional to their degree. Finally, preferential attachment and fitness manifest themselves heterogeneously, depending on either the type or the duration of the network. Preferential attachment drives the cast network evolution, whereas fitness is the main generative mechanism of the crew network. Actors and actresses rely on their status, privilege, and power to obtain future contracts (preferential attachment), whereas technical members are selected on the basis of their talent, skills, and knowledge (fitness). Due to node age or exit, preferential attachment becomes stronger in shorter networks. |

O presente estudo traz uma análise da evolução de redes, especificamente da rede de filmes brasileiros, envolvendo dois mecanismos generativos subjacentes à formação de laços, a saber: ligação preferencial e aptidão. Tanto a ligação preferencial quanto a aptidão podem competir pela modelagem da evolução da rede; portanto, nós desenvolvemos uma nova base de dados com 974 filmes brasileiros de longa-metragem, lançados entre 1995 e 2017 e usamos o PAFit (um novo método estatístico) para estimar os efeitos conjuntos da ligação preferencial e da aptidão na evolução da rede de filmes brasileiros. Os dados coletados e analisados mostraram que a evolução da rede é direcionada tanto pela ligação preferencial quanto pela aptidão. Entretanto, os efeitos da ligação preferencial na evolução da rede tornam-se mais fracos na presença da aptidão. O que significa dizer que a habilidade do nó para formar laços na rede de filmes brasileiros é explicada, principalmente, por sua aptidão; ademais, a ligação preferencial assume uma forma sublinear. Custos, capacidades gerenciais e de comunicação, assim como a idade do nó, explicam por que os nós são incapazes de acumular laços proporcionalmente aos seus graus. Finalmente, observamos que a ligação preferencial e a aptidão manifestam-se heterogeneamente, a depender do tipo, ou da duração, da rede. A ligação preferencial direciona a evolução da rede de atores e atrizes, ao passo que a aptidão é o principal mecanismo generativo da rede de técnicos. Atores e atrizes apoiam-se no status, no privilégio e no poder para a obtenção de contratos futuros (ligação preferencial). Já os membros da equipe técnica, por sua vez, são selecionados a partir de talento, habilidades e conhecimentos (aptidão). A ligação preferencial torna-se mais forte em redes de menor duração em função da idade do nó ou da saída dele da rede.Núcleo de Pós-graduação em Administração, Escola de Administração, UFBA2021-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://periodicos.ufba.br/index.php/revistaoes/article/view/38424Organizações & Sociedade; Vol. 28 No. 99 (2021)Organizações & Sociedade; v. 28 n. 99 (2021)1984-92301413-585Xreponame:Organizações & Sociedade (Online)instname:Universidade Federal da Bahia (UFBA)instacron:UFBAengporhttps://periodicos.ufba.br/index.php/revistaoes/article/view/38424/25445https://periodicos.ufba.br/index.php/revistaoes/article/view/38424/25446Copyright (c) 2021 Organizações & Sociedadeinfo:eu-repo/semantics/openAccess Rocha Tameirão, Cinthya Loureiro Rezende, Sérgio Fernando Pereira de Assis, Luciana 2021-12-01T13:21:14Zoai:ojs.periodicos.ufba.br:article/38424Revistahttp://www.revistaoes.ufba.br/PUBhttps://old.scielo.br/oai/scielo-oai.phpcandidab@ufba.br||revistaoes@ufba.br1984-92301413-585Xopendoar:2021-12-01T13:21:14Organizações & Sociedade (Online) - Universidade Federal da Bahia (UFBA)false |
