The aim of this study is to report assemblage a large multi-institutional international database esophageal cancer patients, patient and tumor characteristics, survival patients undergoing esophagectomy alone its correlates. Forty-eight institutions were approached agreed participate in worldwide collaboration (WECC), 13 (Asia, 2; Europe, North America, 9) submitted data as July 1, 2007. These used construct de-identified 7884 who underwent esophagectomy. Four thousand six hundred...
Problem-based learning (PBL) has been shown to be effective for promoting student competencies in self-directed and collaborative learning, critical thinking, self-reflection tackling novel situations. However, the need face-to-face interactions at same place time severely limits potential of traditional PBL. The requirements space meeting a specific location create timetabling difficulties. Such limitations tackled before all potentials PBL can realized. present study aimed designing...
Phonological access is an important component in theories and models of word reading. However, phonological regularity consistency effects are not clearly separable alphabetic writing systems. We investigated these Chinese, where the two variables operationally distinct. In this orthographic system, defined as congruence between pronunciation a complex character (or phonogram), that its phonetic radical, while indexes proportion neighbors share same phonogram. current investigation, were...
This paper describes the application of state-of-the-art automatic speech recognition (ASR) systems to objective assessment voice and disorders. Acoustical analysis has long been considered a promising approach non-invasive people. In past types amount materials used for acoustical were very limited. With ASR technology, we are able perform linguistic analyses with large natural from impaired speakers. The present study is focused on Cantonese, which major Chinese dialect. Two representative...
We compared the results of 327 transthoracic (TT) resections and 82 transhiatal (TH) for carcinoma oesophagus operated on between July 1982 June 1991. Significantly more patients with lower third (54% versus 28%) increased pulmonary risks surgery (61% 22%) were selected TH approach as TT approach. Results showed comparable intraoperative complications two groups. 5% in group required a thoracotomy control haemorrhage (3 patients) repair bronchial tear (1 patient) which occurred during...
Chinese script is non-alphabetic and a graph basically syllabic which may consist of phonetic semantic radicals with no representation phonemes. The logographeme, unit smaller than radical, has been suggested to be the basic writing based on data collected people aphasia. To better understand role logographemes in development, corpus characters appearing primary school textbooks established. Logographemes are analysed terms features that believed influence development. A total 249 were...
This study examined the existence of a possible relationship between anomic treatment outcomes and executive functions. An ortho-phonological cueing method was used to facilitate object naming in 12 Cantonese-speaking individuals. Treatment effectiveness for each participant quantified correlated with performance functions language tasks. It found that 10 participants showed significant improvement treated items. Eight were able maintain gains at least 1 month. Phonological generalization...
This study investigated a theoretically challenging dissociation between good production and poor perception of tones among neurologically unimpaired native speakers Cantonese. The is referred to as the near-merger phenomenon in sociolinguistic studies sound change. In passive oddball paradigm, lexical nonlexical syllables T1/T6 T4/T6 contrasts were presented elicit mismatch negativity (MMN) P3a from two groups participants, those who could produce distinguish all language (Control) but...
Abstract We report a Cantonese-speaking brain-damaged patient, CML, who demonstrates better oral reading than naming and writing to dictation written naming. Such dissociations are taken as evidence for nonsemantic routes the production of spoken Chinese words. The occurrence tonal errors in CML's aloud informs us about structure phonological representations. propose that it is nonlinear structure, similar which has been proposed phonology Chinese. Specific impairment these representations...
Abstract This paper describes a case study of Chinese brain-injured patient with mild dyslexia and more severe dysgraphia. The distributions his reading writing errors across tasks are consistent previous reports. Semantic predominated in naming both modalities, while the preponderance LARC or phonologically similar plausible writing-to-dictation was found. Furthermore, showed that semantic radical could be replaced, omitted, added, whereas only substitutions deletions phonetic were...
The present study investigated verbal recall of semantically preserved and degraded words nonwords by taking into consideration the status one's semantic short-term memory (STM). Two experiments were conducted on 2 Chinese individuals with aphasia. first experiment showed that they had largely phonological processing abilities accompanied mild but comparable deficits; however, their performance STM tasks revealed a double dissociation. second found participant more better known than unknown...

Coverbal gesture use, which is affected by the presence and degree of aphasia, can be culturally specific. The purpose this study was to compare use among Cantonese-speaking individuals: 23 neurologically healthy speakers, speakers with fluent 21 nonfluent aphasia.Multimedia data discourse samples from these were extracted Cantonese AphasiaBank. Gestures independently annotated on their forms functions determine how gesturing rate distribution gestures differed across speaker groups. A...
Purpose: The existing body of work regarding discourse coherence in aphasia has provided mixed results, leaving the question being impaired or intact as a result brain injury unanswered. In this study, non-brain-damaged (NBD) speakers and with anomic was investigated quantitatively qualitatively.Method: Fifteen native Cantonese 15 NBD participants produced 60 language samples. Elicitation tasks included story-telling induced by picture series procedural description. samples were annotated...
AbstractThis paper describes the use of a Cantonese linguistic communication measure (CLCM) to quantify narrative production aphasic speakers. Four new pictures containing local characteristics were developed, including revised from BDAE (Goodglass and Kaplan, 1993), WAB (Kertesz, 1982) its version (Yiu, 1992), picture depicting Chinese restaurant. The development pictorial stimuli was motivated by lack culturally appropriate for eliciting speech CLCM contains eight indices reflecting...
AbstractBackground: Differences in processing nouns and verbs have been investigated intensely psycholinguistics neuropsychology past decades. However, the majority of studies examining retrieval these word classes involved tasks single-word stimuli or responses. Although results provided rich information for addressing issues about grammatical class distinctions, it is unclear whether they adequate ecological validity understanding lexical connected speech that characterises daily verbal...
Across languages, lexical frequency and age of acquisition (AoA) are important predictors word reading that naturally correlated, both variables have been shown to interact with phonological regularity. Previous behavioral findings in Chinese stronger regularity effects low relative high characters. Meanwhile, the arbitrary mapping hypothesis predicts interference late-acquired irregular words. This study examined neural bases these phenomena using a delayed naming task 480 single...
