As taxas de intera??es na col?nia s?o reguladas pela densidade de indiv?duos que ela cont?m e atrav?s das quais pode haver rapidez na transfer?ncia de informa??o, provocando mudan?as na din?mica de rede social. A fim de analisar o fluxo de informa??o em oper?rias de Dinoponera quadriceps investigamos duas col?nias com base na quantidade de oper?rias e larvas no ninho, n?mero de intera??es individuais, n?mero de sa?das, ?for?a? e ?alcance? de cada intera??o, al?m do fluxo de informa??o em diferentes hor?rios. O estudo foi realizado no Laborat?rio de Biologia Comportamental da UFRN. Foram observadas duas col?nias com diferentes densidades de oper?rias por 16h/col?nia, totalizando 8h/dia atrav?s de grava??o com c?mera digital. As col?nias de D. quadriceps n?o apresentaram correla??o entre o n?mero total de intera??es com o n?mero total de oper?rias e nem com as sa?das do ninho. As taxas de intera??es per capita apresentaram padr?o semelhante para as duas col?nias, sendo maiores no hor?rio com disponibilidade de alimento. A col?nia com menor densidade de oper?rias apresentou mais intera??es por individuo, principalmente no dia e hor?rio com alimento, e estas intera??es obtiveram maior ?for?a? e ?alcance?. A din?mica de redes sociais tamb?m apresentou padr?o semelhante entre as col?nias, apresentando maiores fluxos de informa??o no hor?rio com alimento. Com base no exposto conclu?mos que as oper?rias de D. quadriceps regulam a atividade de forrageamento atrav?s de autoestimula??o, como tamb?m suas taxas de contato, aumentando o n?mero de intera??es em dia e hor?rio com alimento na col?nia, modificando o fluxo de informa??o e aumentando a dissemina??o da informa??o. / Social interactions between workers in a colony do not happen randomly, since workers decide how often they will interact and who they will interact with. Interactions rate in the colony are regulated by the density of individuals it contains and through which can quickly transfer information in the colony, causing changes in network dynamics. In order to analyze the flow of information among workers of Dinoponera quadriceps we investigated two colonies based on the number of workers and larvae in the nest, number of individual interactions, number of outputs, 'strength' and 'reach of each interaction, and also the information flow at different times. The study was conducted in the Behavioral Biology Laboratory at UFRN. Two colonies with different densities of workers were observed for 16h/colony, totaling 8 hours/day by recording using a digital camera. Colonies of D. quadriceps showed no correlation between the total number of interactions with the total number of workers nor to the number of nest exits. The per capita rates of interactions showed a similar pattern in both colonies, being higher during the food availability periods. The colony with lower density of workers had more interactions per individual, especially on the day and period with food, and these interactions got stronger and greater range. The dynamics of social networks also showed a similar pattern among colonies, with greater flow of information during the feeding time. Based on these results we conclude that workers of D. quadriceps regulate foraging activity through self-stimulation, as well as with their contact rates by increasing the number of interactions when food was offered to the colony, changing the flow of information and increasing dissemination of information.

A fundamenta??o te?rica trata da Gest?o da Informa??o e dos fluxos de informa??o nas organiza??es, al?m do fluxo de informa??o no Arquivo Geral, por onde tramitam os processos de aposentadoria anteriores ao SIPAC. Aborda ainda modelos de fluxos e enfatiza a Lei de Acesso ? Informa??o, de n. 12.527/2011, visto que todos os Arquivos P?blicos devem atender a seus preceitos no que diz respeito ? gest?o documental arquiv?stica, ? tipologia documental, ao paradigma custodial e p?s-custodial. Destaca a import?ncia do tratamento, da conserva??o dos suportes de papel dos processos de aposentadoria danificados sob a guarda no Arquivo Geral. Na metodologia, utiliza abordagem qualitativa e a estrat?gia de pesquisa-a??o. Para tanto, faz uso de instrumentos de coleta de dados como: pesquisa documental, observa??o participante e entrevista semiestruturada. Entre os sujeitos respondentes da pesquisa constam o primeiro diretor do Arquivo Geral, os servidores atuais do referido arquivo, alguns servidores do Departamento de Administra??o de Pessoal, al?m de um bolsista de apoio t?cnico que atua no Arquivo Geral. Para o tratamento dos dados, utiliza a an?lise de conte?do, nesse sentido, foi elaborado um projeto piloto composto de 20 processos de aposentadoria sob a guarda do Arquivo Geral, no per?odo de 1965 a 2002, os quais ainda n?o est?o cadastrados no sistema SIPAC. Como resultado, para o tratamento e a conserva??o dos suportes, sugere aperfei?oar o fluxo dessa documenta??o por meio da higieniza??o, do cadastramento no SIPAC. Em rela??o ao acondicionamento, sugere um modelo de embalagem, preservando assim, os processos f?sicos. / This paper investigates information and information flows management at General Archive of Universidade Federal do Rio Grande do Norte (UFRN). The baseline is the retirement processes, which precede Sistema Integrado de Patrim?nio, Administra??o e Contratos (SIPAC), created in 2003. Theoretical foundation is about information and information flows management in organizations, besides information flow at General Archive, where retirement processes preceding SIPAC are handled. It also considers flow models and emphasizes the Access to Information Law - LAI - (Law 12 527/2011), since every public archive must meet its requirements relating to archival documental management, documental typology and custodial and post-custodial paradigm. We focus on the relevance of handling and preserving the paper supports of damaged retirement processes under the General Archive guard. In Methodology, we do a qualitative approach and action research strategy, using data collecting instruments such as documentary survey, participating observation, semi-structured interview and quiz. The research subjects are the General Archive first director, archive active public servants, some agents from Personnel Administration Department and an assistant for technical support. To analyze data, we use content analysis. For that purpose, a pilot project was elaborated; being composed by 20 retirement processes under General Archive custody, from 1965 to 2002, which are still not registered in SIPAC system. As a result, to the treatment and conservation of supports it suggests improve documents flow by cleaning, and registering in the SIPAC system. Related to the keeping documents, it suggests a better packing model to preserve physical processes.
