The noticed advantage of using this extension is that it does not separate the terms that form a keyword when generating the cloud. At last, a word cloud was created using the Wordcloud 2.5 extension (Fellows, 2013). (2010) suggest that an analysis should be performed from the hierarchical tree, thus the number of clusters can be defined considering the overall appearance (or shape) of the tree formed. The function allows forming as many clusters the researcher wishes, being of its attribution to analyze a division that best represents the characteristics of the data (Husson, Josse, and Pagès, 2010). This function allows creating clusters from the characteristics of the articles analyzed and highlights the justifications for the groupings created. ![]() By using the FactoMineR 1.34 extension, the hierarchical clustering on principal components (HCPC) function was used (Husson et al., 2007 Lê et al., 2008). The characteristics considered for carrying out MCA were the “main term”, “research approach”, “type of research”, “constructs” and “research strategies”. In the present research, multiple CA (MCA) was applied – indicated when the elements are described as categorical variables (Lê et al., 2008). This extension is dedicated to the multivariate analysis of data and allows the manipulation of different types of variables (quantitative or categorical). CA is a multivariate exploratory technique that converts a data matrix into a graphical representation, so that rows and columns are represented by points in a graph (Greenacre and Hastie, 1987). Correspondence analysis (CA) was also performed. This extension is able to manipulate networks with millions of vertices and edges and provides a series of functions to analyze the properties of social networks, such as subnetworks, intermediation, centrality, among other characteristics (Csárdi and Nepusz, 2006). The IGRAPH 0.5.5-2 extension (package) was used to analyze graphs and co-authorship networks (Csárdi and Nepusz, 2006). The R 3.3.2 and R Studio 1.0.136 software were used. It has been identified that 77 articles were published in eight journals. The procedures suggested by Crossan and Apaydin (2010) for conducting bibliometric studies were adopted. However, it was decided to analyze ten of them. ![]() In total, 12 “A” concept journals were identified. Design/methodology/approach – This paper uses national journals with Concept “A” of the Qualis classification (2016) for journal selection. Purpose – The present study seeks to answer the following research question: what is the profile of the academic production related to the interorganizational networks in the period between 20? Thus, this study aims to characterize the academic production about the subject interorganizational networks available in national journals with Concept“A” (Qualis Capes), in the period between 20.

This information can be used to improve orbital image quality and avoid misinterpretation of image artifacts. ![]() Protocol errors may cause artifacts such as saturation, phase wraparound, truncation, shading, and partial-volume artifacts. Artifacts due to a nonuniform magnetic field are particularly noticeable at air-tissue interfaces but may also be caused by incomplete fat saturation or highly magnetic materials near the orbit. Motion artifacts are caused primarily by unavoidable globe motion during imaging. Chemical shift artifacts may be induced by orbital fat or silicone oil used to treat retinal detachment. However, there are a number of artifacts and pitfalls associated with orbital MR imaging. High-resolution magnetic resonance (MR) imaging of the orbit has become widely accepted as a valuable diagnostic technique.
