as them as if they had been created by

as almost the same in all categories. These preliminary results are discussed in more detail in the following sections.  As can be seen from the above table, the patterns of use of first person singular pronouns and possessive adjectives in the corpus were very different from the ones of plural pronouns, which was not surprising given that only eleven of the 60 articles were single-authored. As mentioned before, this paucity of single-authored articles could ultimately be explained by the fact that research in some areas is expected to be the result of the joint effort of a team of researchers, which makes it difficult for individual researchers to stake claims individually. Based on what Becher (1989) points out, team work is more common in “urban” disciplines, where the number of hot issues for research is limited and there is a higher competition and more intense interaction among disciplinary members. Interestingly, researchers in their disciplines actually do write some articles on their own, although in some cases it seems to be common practice to compose them and publish them as if they had been created by the whole group of specialists.  While the personal pronouns “I” “my” and “me” were non-existent in all four disciplines analyzed, the pronouns “we” “our” and “us” were frequent. A number of single authors in all disciplines decided to avoid using exclusive first person pronouns altogether or, perhaps more surprisingly, opted for the use of exclusive plural pronouns and possessive adjectives rather than singular ones when referring to themselves in their text. In sum, there seems to exist a degree of variation among individual authors as to the ways in which singular pronouns and possessives were used in single-author RAs in the disciplines studied. However, a deeper investigation of this aspect of pronoun use would require a fully comparable corpus of single-author and multiple-author RAs in each discipline, such analysis is beyond the scope of the present study. According to the results (Table 4-1), there was also a very large difference in the incidence of the two plural first person pronouns analyzed in the corpus, namely “we” and “us”. The exclusive subject pronoun “we” was used very frequently in all the subcorpora except for Life Sciences, where its incidence was notably low (81). The highest values were found in a discipline belonging to Physical Sciences and Engineering. The results for the use of personal markers in RAs were in apparent conflict with the traditionally
