This study analyzes the possible occurrence of plagiarism and self-plagiarism in a sample of articles published in the Scientific Periodicals Electronic Library (SPELL), an open database that indexes business journals in Brazil. The author compared one sample obtained in 2013 ( n = 47 articles) and another selected from 2018 ( n = 118 articles). In both samples, we verified the guidelines that each of the journals provided to authors regarding plagiarism and the adoption of software to detect textual similarities. In the analysis conducted in 2013, it was found that only one journal (2%) mentioned the word “plagiarism” in its policies, although the majority of the directives required guarantees that no type of violation of authors’ rights was contained in the manuscript. In the analysis conducted in 2013, it was determined that there were literal reproductions in 31 published articles (65.9%), and no relevant similarities with other publications were encountered in 16 articles (34.1%). In the 2018 analysis, 69 of the publications (58%) included observations and guidelines related to plagiarism and self-plagiarism. In the analysis conducted in 2018, it was found that similarities (plagiarism and self-plagiarism) occurred in 52 articles (44%), and no relevant evidence of plagiarism or self-plagiarism was found in 66 (56%) manuscripts. Although a reduction in the index of the occurrence of plagiarism was observed, as was an increase in the instructions on the prevention of plagiarism by authors, practices directed at guiding authors by means of directives concerning the importance of preventing plagiarism in manuscripts submitted for publication can be recommended.

在科学期刊电子图书馆（SPELL）收录的期刊上发表的文章中存在窃：2013年至2018年之间的比较分析

这项研究在科学期刊电子图书馆（SPELL）中发表的文章样本中分析了窃和自我pla窃的可能发生，该期刊是对巴西商业期刊进行索引的开放数据库。作者比较了2013年获得的一个样本（n = 47篇文章）和2018年选择的另一个样本（n = 118篇文章）。在这两个样本中，我们验证了每本期刊向作者提供的有关窃和采用软件来检测文本相似性的指南。在2013年进行的分析中，发现只有一本期刊（2％）在其政策中提到了“抄袭”一词，尽管大多数指令都要求保证手稿中不包含任何侵犯作者权利的行为。 。在2013年进行的分析中，经确定，有31篇文章（65.9％）有直译，而在16篇文章（34.1％）中未发现与其他出版物的相似之处。在2018年的分析中，有69篇出版物（58％）包括与窃和自pla有关的观察和指南。在2018年进行的分析中，发现有52篇文章（44％）存在相似性（抄袭和自-），而在66篇（56％）手稿中未发现任何relevant窃或自-的相关证据。尽管发现抄袭发生的指数有所下降，但作者关于预防窃的说明有所增加，
