Contributing factors to academic achievements: from community college to university in Hong Kong
No full text[EN] Academic achievement of students transferring from community colleges to 4-year institutions has been a topic of interest to educational researchers globally. However, local empirical evidence remains limited on how transfer students’ learning approaches and the teaching-learning environment relate to their academic achievement in Hong Kong’s universities. The study aims at exploring the relationship between transfer students’ approaches to learning, their perceptions of the teaching-learning environment and academic achievement. The participants were 617 undergraduate students transferring from community colleges to an university in Hong Kong. Students’ approaches to learning and perceptions of the teaching-learning environment were measured using the HowULearn questionnaire. Analyses were carried out using factor analysis, Pearson correlation and linear regression. The results confirmed positive relations between students’ perceptions, approaches and achievement. Students studying in an organised manner achieved better academic performance, whereas those using a surface approach poor performance. Others might also adopt an intermediate approach to learning. The results indicate that promoting awarenesses of choosing and using appropriate learning approaches is important for fostering academic success among students.Li, Y.; Li, B.; Cheung, K.; Tsang, H.

Anti-transfer effects in third language acquisition
No full textRecent work has established that reverse transfer from L3 to L2 can occur, resulting in transfer in domains such as tense-aspect (Cheung, Matthews and Tsang 2011). A related possibility which has been less widely discussed is that L1 effects on L2 can be modulated by subsequent acquisition of an L3. Studies in the Hong Kong context suggest that this is a real possibility. L3 learners at universities who have been exposed to Cantonese and English from early on show influence of Chinese in their L2 English. For example, Hui (2010) found that speakers who learnt French as L3 were less prone to produce ill-formed subject relative clauses as in (1) in their English. (1) *The one stood outside 10B has a ponytail. Also prominent among the interlanguage features of Chinese learners are morphological errors in English, such as use of uninflected verbs referring to the past (2): (2) Last week I see a movie. In a written production task, L3 learners of German were found to produce errors of this type at approximately half the rate of bilingual controls without knowledge of German. We attribute this finding to the systematic tense inflection in German sensitizing learners to the need for morphological marking of tense. These are not merely cases of reverse positive transfer, since the effect apparently involves expunging errors resulting from L1 transfer. We therefore suggest the term anti-transfer effects for this phenomenon. We discuss how anti-transfer effects may be further investigated and their potential importance for applied linguistics
Some Weighted Hardy-type Inequalities of Vector-Valued Functions
No full textBy adopting the C-technique of Cheung and Pečrić, we establish some interesting weighted Hardy-type inequalities of vector-valued functions. These generalize and improve some existing results of Cheung, Cheung-Hanjš-Pēcarić, Hanjš-Love-Pečarić, Levinson, and Pachpatte. [ABSTRACT FROM AUTHOR

<div><strong>Abstract</strong></div>
<div>A major goal of systems biology is the development of models that accurately predict responses to perturbation. Constructing such models requires the collection of dense measurements of system states, yet transformation of data into predictive constructs remains a challenge. To begin to model human immunity, we analyzed immune parameters in depth both at baseline and in response to influenza vaccination. Peripheral blood mononuclear cell transcriptomes, serum titers, cell subpopulation frequencies, and B cell responses were assessed in 63 individuals before and after vaccination and were used to develop a systematic framework to dissect inter- and intra-individual variation and build predictive models of postvaccination antibody responses. Strikingly, independent of age and pre-existing antibody titers, accurate models could be constructed using pre-perturbation cell populations alone, which were validated using independent baseline time points. Most of the parameters contributing to prediction delineated temporally stable baseline differences across individuals, raising the prospect of immune monitoring before intervention.</div>

HIFU 治疗患有肝硬化的原发性肝癌病人
No full textHepatocellular carcinoma (HCC) is one of the commonest cancers in Asia. However, only a small amount of patients is eligible for surgical intervention upon diagnosis. Treatment planning for patients with HCC remains a great challenge to most clinician. In Asia, most of the HCC patients are hepatitis B carrier. The bad combination of liver cancer and hepatitis B related cirrhosis make liver resection impossible in most of the patients.1 Radiofrequency ablation (RFA) is one of the very effective and simple treatment methods for HCC which can achieve survival similar to liver resesction for HCC smaller than 2cm. However, RFA may not be well tolerated in patients with cirrhosis and severe complication may follow after prolonged ablation.2 Transarterial choemoembolization (TACE) is a widely used treatment option for unresectable HCC and its effect has been shown to be better by best symptomatic treatment by randomised controlled studies.3 However, the survival outcome of TACE is not very appealing as the 2 year survival is around 30%. High intensity focused ultrasound (HIFU) is a totally non invasive ablation treatment modality. 4. Our center started offering HIFU treatment in 2006 as a non-invasive mode of surgical ablation for patients who could not tolerate liver resection because of poor liver reserve.5. Our initial results showed that the complete ablation rate with single ablation was 89.2%.6. Up to date, we have performed more than 200 cases of HIFU ablation to treat HCC and no postoperative liver failure has been recorded. HIFU ablation was safely performed in the present case even though the patient had thrombocytopenia. The unique needleless design of the HIFU system makes HIFU ablation superior to RFA, for needle penetration may induce hemorrhage from a hypervascular tumor in a patient with coagulopathy and low platelet count. Furthermore, without needle
puncture, there is no risk of direct tumor seeding to the surrounding major vessels. 4,7 In conclusion, HIFU ablation is a potentially curative measure which seems to be safe and effective for patients with unresectable HCC.
