a growing body of research has indicated that students of esl/efl are reticent and unwilling to be engaged in oral activities in english lessons. communicative language ability includes speaking ability, so vocabulary knowledge plays an integral role in speaking a language. however, there have been few studies examining the degree to which vocabulary knowledge affects speaking ability. the pres...

Lexical items in the vocabulary of a language undergo dramatic changes over time, explaining the mechanisms that cause this change has been an important topic for the cognitive sciences. One particular focus for researchers has been understanding the dynamics of change in word forms. The rate (or half-life) at which word forms change over time varies greatly, and corpus-based cladistic studies ...

Histogram pyramid representations computed from a vocabulary tree of visual words have proven valuable for a range of image indexing and recognition tasks; however, they have only used a single, fixed partition of feature space. We present a new efficient algorithm to incrementally compute set-of-trees (forest) vocabulary representations, and show they improve recognition and indexing performan...

Introduction: Literature regarding the different degrees of hearing loss in patients with Cornelia de Lange syndrome (CDLS) reports that half of the affected patients exhibit severe to profound sensorineural hearing loss. We present the first pre-school child with CDLS who underwent cochlear implantation for congenital profound sensorineural hearing loss.   Case Report: A 3-year-old boy with CD...

This study has examined the effect of semantic mapping on learning vocabulary across genders. The researchers selected 120 intermediate students after the administration of a standard proficiency test. A vocabulary test was also used to measure the students’ vocabulary knowledge. The experimental group received semantic mapping in the pre-reading stage, butthe control group did not receive this...

Background Establishment of viable pregnancy requires embryo implantation and placentation. Ectopic pregnancy (EP) is a pregnancy complication which occurs when an embryo implants outside of the uterine cavity, most often in a fallopian tube. On the other hand, an important aspect of successful implantation is angiogenesis. Vascular endothelial growth factor (VEGF) is a potent angiogenic factor...

Vocabulary learning is considered to be the most comprehensive and the most difficult part of language learning for all the students especially for ESP students. These students complain that vocabulary items are too many and are easily forgotten after they are learned. Mnemonic devices, a group of mental strategies, are developed to facilitate vocabulary learning and retention for such students...
