academic discourse

There has been increasing interest in utilizing corpora in linguistic research and pedagogy in recent years. Rhetorical organization of different sections of research articles may appear similar in various disciplines, but close examination may show subtle differences nonetheless. One of the features that has been at the center of attention especially in recent years is the idiomaticity of a discourse which can be examined from the perspective of multi-word units captured by the automatic retrieval of lexical bundles. This study takes a corpus-based approach for the identification of lexical bundles. A corpus of 801,894 words from 790 articles was collected. In order to fulfill the purposes of the present study, ABBYY FineReader 10 professional edition, Total Assistant, Antconc 3.2.3, and WordSmith Tools 5 were used to identify lexical bundles. Then these bundles were classified structurally and functionally based on the presented taxonomies in the literature. The results of the current study indicated that the writers of medical research articles mostly rely on text-oriented bundles in the discussion section of research articles to establish academic discourse.

L2 language socialization asks how learners come to gain the ability to write appropriately and sufficiently in an institutional academic community of practice. In the same line, this study focuses on the process of socialization of an Iranian English L2 essay writing class in the context of higher education. The theoretical backgrounds rely on the socialization and Vygotsky's sociocultural theories. Three case studies were analyzed throughout six weeks. The learners' essays, outlines, and reflective diaries were analyzed to trace their development in appropriating academic discourse and argumentation. Also, an interview session was held at the end of the study in which the issues regarding the whole experience of socialization were discussed with the participants. The results suggested that each learner pursued their path of socialization based on their individual and social needs of the academic discourse community. Accordingly, a model demonstrating their paths of development is presented. The model shows that the new-comers to this social site of engagement were mediated by the old-timer agent of practice (instructor) to appropriate the values, principles, and behaviors of this community of practice through the activities they were engaged in.

Research on the special relationship between the United States and Israel has usually been focused on strategic aspects, whilst fewer scholars have focused on non-material dimensions of the relationship. In addition, the existing research is mostly confined to the political and decision-making realms, with very few excursions into the academic arena. The current article aims to fill this lacuna through the study of pro-Israel academic discourse in America, focusing on the specific case of the field of terrorism studies. Critical discourse analysis of pro-Israel academic texts in this field is carried out to reveal the discourse, themes and arguments used to build this ideational pillar of the special relationship and move towards a common identity between the US and Israel. The common ingroup identity model (CIIM) is used to describe the process through which a common identity is constructed. The article concludes that defining the Self, defining the Other, and defining the norms are the three main strategies employed in the studied texts to achieve this goal.
