Marketization in all public spheres including academic discourse has led to the increased importance of promotion. One of the promotional tools usually used in Research Articles Introductions (RAIs) is claiming centrality which can be realized through different linguistic and textual resources. In this study, our aim was to explore differences between native and non-native writers in the use of strategies for claiming centrality in RAIs. To this end, a corpus of 50 RAIs (25 L1 and 25 L2 which were written by native English and non-native Iranian writers, respectively) was compiled and analyzed in terms of the strategies used for claiming centrality introduced by Wang and Yang (2015). The introductions were read through closely and the types and orientations of the strategies were identified. Then, the two sub-corpora were compared to highlight differences and/or similarities. The results showed that the mean occurrence of centrality claims in general is nearly the same in both groups of texts while in terms of the specific strategies employed to make such claims there are some differences between them. The findings of this study can serve EAP/ESP practitioners and learners as well as those wishing to publish their research internationally by raising their awareness in this regard and helping them report their research findings more convincingly.

通过在L1和L2英语中占据中心地位来进行推广

所有公共领域的市场化，包括学术话语，都导致促进的重要性日益提高。研究文章简介（RAI）中通常使用的促销工具之一是声称具有中心性，可以通过不同的语言和文字资源来实现。在这项研究中，我们的目的是探索在使用RAI的核心地位的策略使用方面，本地作者与非本地作者之间的差异。为此，根据Wang和Yang（2015年提出的主张中心性的策略）汇编并分析了50个RAI的语料库（分别由本地英语作者和非本地伊朗作家编写的25 L1和25 L2）。 ）。仔细阅读了介绍，并确定了策略的类型和方向。然后，比较了两个子语料库以突出差异和/或相似性。结果表明，在两组文本中，集中性声明的平均出现率几乎相同，而就提出此类声明所采用的具体策略而言，它们之间存在一些差异。这项研究的结果可以提高EAP / ESP从业者和学习者的意识，并帮助他们更有说服力地报告他们的研究结果，从而为EAP / ESP从业者和学习者以及希望在国际上发表其研究的人们服务。
