This longitudinal case study tracks an adult second-language (L2) learner’s quality and quantity of encounters with 20 vocabulary items in an English for Academic Purposes course over 3 months. The learner completed pretest and posttest vocabulary knowledge interviews, submitted course materials and notes for analysis, and was observed during class lessons. The results show that frequency of en...

A comparison has been made of productive vocabulary in some normal university English majors’ theses in China and American final-year undergraduates’ papers. The research demonstrates that with family as the measurement unit, Chinese students proportionally use fewer words of the 1 st , 8th to 10th 1000 frequency level words than American students, while in terms of the 2nd to 4th 1000 frequenc...

Language used to describe resources in an institutional repository may benefit from the consistency offered by a controlled vocabulary as well as introduction into the larger linked data universe. Transitioning to a linked data vocabulary presents concerns regarding the effectiveness of mapping pre-existing terms and the potential for semantic loss. This paper describes such a transition to OCL...

The purpose of this study was to create a means for comparing the vocabulary levels of Japanese junior and senior high school (JSH) texts, Japanese college qualification tests, English proficiency tests, and EGP, ESP and semi-ESP college textbooks in order to determine what the vocabulary levels are, and what additional vocabulary is required for students to understand 95% of these materials. T...

Mid-wave infrared (MIR, 3–5 µm) optical frequency combs (OFC) are of critical importance for spectroscopy fundamental molecular transitions in space and terrestrial applications. Although this band OFCs can be obtained via supercontinuum or difference generation using pumping schemes, unprecedented source miniaturization, monolithic design unique to electrically-pumped semiconductor laser struc...
