Investigating the relationship between linguistic changes in L2 writers’ paraphrasing, paraphrasing performance and L2 proficiency

While the typology of paraphrasing revolves around linguistic changes of paraphrasing, little is known about the importance of different types of linguistic changes and their relationship between paraphrasing performance and L2 proficiency. Empirical enquiry has focused on L2 writers’ inappropriate paraphrasing performance against the norm of L1 writer, which is problematic in that L2 and L1 writers displayed considerable variation in paraphrasing. The present study drew upon 202 Chinese EFL writers’ written responses in a paraphrasing test to look into the discrete linguistic transformations in paraphrasing and examine how the frequency of different linguistic changes in paraphrasing relates to their paraphrasing performance and L2 proficiency. Correlation analysis was run to analyze the relationship between the frequency of linguistic changes and paraphrasing performance. Multivariate analysis of variance analysis was conducted to examine how the frequency of linguistic changes relates to L2 proficiency. The findings revealed that Conceptual Transformation had the highest significant correlation with paraphrasing scores, followed by Lexical Transformation and then Syntactic Transformation. The frequency of Synonym Substitution, Morphology, Multiple Word Units, Phrase/Clause Shift, Active/Passive Shift and Conceptual Transformation increased as L2 writers’ proficiency levels increased. Implications are drawn from the findings for paraphrasing instruction and assessment, research in paraphrasing and L2 writers’ academic writing practice.

An Antonym Substitution-based Model on Linguistic Steganography Method

<p class="IJASEITAbtract"><span lang="EN-GB">This paper implement the antonym procedure in substitution-based approach for linguistic steganography that is expected to be an alternative to the existing substitution approach that using synonym. This method is hidden the message as existing approach, however that is changing the semantic of the stego text from cover text as the medium. This paper proposed the development method is named Antonym Substitution-based that applied based on implementation linguistic steganography in covering the secret message. This approach refines the word choices makes antonym substitution-based approach linguistically is comparable with the previous effort of synonym substitution. Furthermore, this paper also used the verification and validation approaches as the procedure to evaluate performance of this method. The evaluation through verification approach used in order to determine the effectiveness and quality performance. This proposed method is expected has become the new technique implementation of linguistic steganography in process securing secret message that hide in the text medium.</span></p>

The duck cytochrome oxidase I (COI) gene: Sequence and patterns analysis for potential barcoding tool

Susanti R, Iswari RS, Fibriana F, Indriawati. 2018. The duck cytochrome oxidase I (COI) gene: Sequence and patterns analysis for potential barcoding tool. Biodiversitas 19: 997-1003. The local duck DNA barcoding is still rarely conducted in Indonesia while DNA barcoding is extensively used as a tool of species identification and delineation tool. This study aimed to analyze the sequence and patterns of Central Javanese ducks mitochondrial cytochrome c oxidase subunit 1 (COI) gene. Feather samples of seven breeds of native duck were collected from traditional husbandries in Central Java. The samples were employed for DNA extraction and COI gene amplification. Five haplotypes were obtained from 35 samples, i.e., haplotype A, B, C, D, and E. Also, 9 variable sites with synonym substitution was detected in four nucleotides number 55, 61, 100, and 109; whereas five synonym substitutions were identified in the nucleotides number 36, 48, 51, 66, and 756. In conclusion, this study annotates that COI mtDNA gene is essential for local ducks barcoding system.
