Perceptions of authorial identity in academic writing among undergraduate accounting students: implications for unintentional plagiarism

The current study explores first, second and third year UK accounting students’ perceptions of authorial identity and their implications for unintentional plagiarism. The findings suggest that whilst all students have reasonably positive perceptions of their authorial identity, there is room for improvement. Significant differences in second year students’ perceptions were reported for some positive aspects of authorial identity. However, results for negative aspects show that second year students find it significantly more difficult to express accounting in their own words than first and third years. Furthermore, second years are significantly more afraid than first years that what they write will look unimpressive. Finally, the results for approaches to writing, which also have implications for unintentional plagiarism, revealed that students across all years appear to adopt aspects of top-down, bottom-up and pragmatic approaches to writing. Emerging from these findings, the study offers suggestions to accounting educators regarding authorial identity instruction.

Plasmid pRTL1 controlling 1-chloroalkane degradation by Rhodococcus rhodochrous NCIMB 13064

Rhodococcus rhodochrous NCIMB13064 can dehalogenate and use a wide range of 1-haloalkanes as sole carbon and energy source. The 1-chloroalkane degradation phenotype may be lost by cells spontaneously or after treatment with Mitomycin C. Two laboratory derivatives of the original strain exhibited differing degrees of stability of the chloroalkane degradation marker. Plasmids of approximately 100 kbp (pRTL1) and 80 kbp (pRTL2) have been found in R. rhodochrous NCIMB13064. pRTL1 was shown to be carrying at least some genes for the dehalogenation of 1-chloroalkanes with short chain lengths (C-3 to C-9). However, no connection was found between the utilization of 1-chloroalkanes with longer chain lengths (C-12 to C-18) and the presence of pRTL1. Three separate events were observed to lead to the inability of NCIMB13064 to dehalogenate the short-chain 1-chloroalkanes; the complete loss of pRTL1, the integration of pRTL1 into the chromosome, or the deletion of a 20-kbp fragment in pRTL1. High-frequency transfer of the 1-chloroalkane degradation marker associated with pRTL1 has been demonstrated in bacterial crosses between different derivatives of R. rhodochrous NCIMB13064, (C) 1995 Academic Press, Inc.
