Brazil is the world's largest broiler meat exporter. Health control, knowledge and technology, as well as the natural aspects of the country are pointed out as the keys for the success of that product in the market. Brazilian broiler production grew significantly in the last decade; it creates jobs and has a significant social role in Brazilian economy. This study aimed at evaluating the Brazilian broiler meat supply chain from 2000 to 2010 using the social network analysis (SNA). Data from governmental and private sources were organized and analyzed. The focus of this study was the broiler production supply chain segment involving the hatchery, the broiler farm, the feed mill, the processing plant, and the government. The inputs considered were one-day-old chicks, pullet, feedstuff, and the infrastructure; and the outputs were broiler meat and taxes paid. The software UCINET was applied for calculating the structural attributes and indicators of the network. Results showed a relatively disorganized network in 2000 with the strongest tie between the farmer and the processing plant. The structural organization of the network improved until 2010. The density of the ties in the broiler meat production network increased steadily from 2000 to 2010 within a vertical cohesive supply chain structure. The success of Brazilian broiler meat production is attributed to the abundance of land, fertile soil, favorable climate, and the effort and investments in research and development by innovative companies in the last few years. The results of the present study showed that Brazilian broiler production evolved positively in the last ten years, and it was weakly influenced by international challenges.

Brazil is one of the world's largest broiler meat exporters. Broiler meat is one of the most consumed meats worldwide. The most significant challenge for strategic business management when optimizing the financial returnis knowing exactly where to invest. The same happens in the broiler production chain. The present research aimed to investigate which were the most central actors in the broiler supply chain and the dynamics of the chain. The current study was done based on the poultry chain business relations, from 2000 to 2015, of the leading actors of the Brazilian broiler production chain. The centrality indicator was established through social network analysis (SNA) approach, to determine their positions in the chain as a whole. The most used indicators within network analysis are those designed to identify the extent to which one actor occupies a more central position than another. The Gephi ® software was applied to calculate the structural attributes and indicators of the network. Results were estimated using the RapidMiner ® software. A model was presented that shows one infrastructure indicator as an explanatory variable. The findings indicate that the centrality indicator was weakly influenced when compared to the other variables, such as market demand, wide variations on the scenario, and mergers or acquisitions.

Retail has undergone several transformations over the years. The main reason is due to the digital transformation that is occurring in business, changing all processes and, as a consequence, consumer behavior. This new retail model, much more interactive and integrated, is taking over the market. Retail distribution systems are considered multi- or omni- channel systems when consumers can place orders to buy products: online, physically and online in the stores. Nowadays, most companies try to increase their sales using this recent business model called omni-channel retailing. This is changing the way companies sell their products. These changes can be seen both in the internal logistics of retailers and in the structure and processes of the supply chain. It integrates two existing distribution systems: the retail distribution system and the consumer distribution system. The current study aims to understand this model that integrates the digital and offline and raise its key implications for the strategies applied in logistics.

With growing interest worldwide in the use of liquid biofuels in the transport sector, ethanol is considered as one of the best alternatives. Rising oil prices, environmental concerns and interests in energy security have driven Brazilian researchers to look to biofuels production as a potential solution. Other driving forces are the need to stabilize commodity prices and cut down on agricultural subsidies. This paper describes the analysis of Brazilian large-scale network of ethanol production and lead to answer issues related to the sustainable development indicators by studying the structural characteristics of the production chain through social network analysis (SNA). The result showed two structural indicators that monitor the growth of the production chain and also indicates sustainability, based on the fact that no major change occurred in the area planted with sugarcane. The increasing power of distributors is noticed by the increase of the degree of centrality and the strengthening of the chain which is visible through the density evolution.

Abstract. Communications agencies are private organizations that have a fundamental role in marketing and communication markets. Following this perspective, this study, with the support of Social Network Analysis tools, the structure of an agency will be modeled with the purpose of identifying the most important actors and its relationships, and show its interdependence with the workflow of the production chain. To achieve compatible results with the organization goals, it is important that their areas or teams relate with one another so as to optimize their production processes. With support of the Ucinet ® software and its integrated module NetDraw ® , this paper describes through a case study, how to implement this innovative approach and follow the evolution of the network in order to improve their operational performance. The results pointed out an increase in productivity after the analysis and change in the organization's internal communication.
