title: A corpus-based study of specialized vocabulary from American political news articles: an analysis of lexical items

description: This study investigated the most frequent specialized vocabulary items of American political news articles from four websites, namely BBC, The Guardian, CNN and Fox News. The size of corpus from each website was approximately 50,000 words, so the total words of this American political corpus was roughly 200,000 words. Compleat Lexical Tutor was used to generate vocabulary profile and AntConc was used to explore the most frequent words and their collocations. Moreover, the data from these programs was compared to see more information and ideologies from the viewpoint of American politics in each website. It was discovered that all four websites had high density of vocabulary, in other words, the American political article is challenging for readers. In addition, the frequent keywords from each website imply interesting information. This means that each website focused on different American political issues. The results also revealed the British websites were likely to present American political issues which affected other countries, but the US websites tended to report about the US president and his administration. Moreover, when analyzing the concordance lines, it was found that Fox News appears as pro-Republican.

title: A corpus-based analysis: the need of using “therefor” and “thereunder” in legal documents

description: This study is to analyze the usage of adverbs “therefor” and “thereunder” and investigate the differences of using them in legal documents between native and non-native English speakers.  Corpus-based analysis software, namely “AntConc”, was used to analyse these two words.  The analytic corpus consisted of 1,511,820 words from legal documents that were written by native and non-native English speakers between the years 2015-2016.  Regarding the grammatical patterns, the results confirm that these two words are adverbs because, overall, they are generally found in positions that would indicate as adverbs.  In reference to the frequency use of “therefor”, it was used 0.0097% and 0.0077% for “thereunder”.  The results between these two words are not substantially different.  After analyzing the frequency use of “therefor” between native and non-native English speakers; surprisingly, the results showed that the non-native group used “therefor” more than the native group.  The non-native group used “therefore” at 0.0115%; and the native group used it at only 0.0072%.  The difference between them is 0.0043%.  Contrary to that, for the word “thereunder”, the results from the native group are higher than the non-native group.  The native group uses “thereunder” at 0.0148% and only 0.0006% for the non-native group.  The difference between these two results is 0.0142%, which are really high.  Nevertheless, the results from both groups are still less than one percent usage.  This means that both groups rarely use “therefor” and “thereunder”.  However, less than one percent is not zero percent; legal writing teachers may use the finding of the study as partial information when they design their legal writing courses materials.

title: Student's attitudes toward using the iTunes U application in English for business

description: This study aimed to investigate students’ attitudes toward using the iTunes U Application in an English for Business class in Thailand. The participants were thirty students who enrolled in an English for Business class in 2016. The participants were required to use the iTunes U Application which contains the English for Business contents for three weeks. To complete the objective of this study, the questionnaires, consisting of both positive and negative questions, were used to collect the data. Some open-ended questions were also included. The data was analyzed using descriptive data. The findings indicate that Thai students have positive attitudes toward using the iTunes U Application in English for Business. However, there were still some problems relating to comprehension of vocabulary which occurred when the application was used in the class.
