One of the ways to achieve such an acceptance is by establishing intertextual links to prior research using citation. Despite a vast research on the topic and suggestion of typologies for the form and function of citation in ...

The present corpus-based lexical study reports the development of a Pharmacy Academic Word List (PAWL); a list of the most frequent words from a corpus of 3,458,445 tokens made up of 800 most recent pharmacy texts including research articles, review articles, and short communications in four sub-disciplines of pharmacy. WordSmith (Scott, 2017) and AntWordProfiler (Anthony, 2014) were used to sc...

In light of the understanding that the analysis of the generic features of different academic genres can enhance the ability of non-native members of academic discourse communities to understand, and where appropriate, to produce them, the present study aimed at investigating the dominant generic structure of research articles in mathematics. To start with a relatively narrow focus, a corpus of...

More recently, several articles (see, e.g., [1, 3–8]) address the problem of determining when certain operations between nonderogatory digraphs are again nonderogatory...
