Doing science through translanguaging: a study of translanguaging practices in secondary English as a medium of instruction science laboratory sessions

This study explores how students in a joint process of knowledge construction through the use of multilingual and multimodal resources in groups promotes the learning of scientific concepts in the context of laboratory work. Inductive qualitative discourse analysis was conducted to examine how students’ translanguage in a group completing tasks in two Grade 10 secondary science labs (biology and chemistry) in a Hong Kong EMI secondary school and how such a joint process of knowledge construction promotes the learning of scientific concepts. Using translanguaging as a theoretical framework, the analysis shows that even though schools have imposed an English-only policy, students use their linguistic and semiotic resources to both co-construct their scientific knowledge and practise their science apprenticeship. Translanguaging plays a role in mediating the students’ understanding of science, facilitating peer work and creating an enjoyable learning environment in the lab. The result implies that translanguaging as a pedagogical tool may create a space for content subject learning in Hong Kong EMI school setting

The building of a new business ecosystem: Sustaining national competitive advantage through electronic commerce

Despite the high level of interest in the role of governments in building national information infrastructure (NII) as a source of competitive advantage, it is still not clear how major information technology initiatives can help leverage national economies into the global marketplace. In light of the recent rollout of one of the world's largest electronic commerce initiatives, we examine the role of private-public partnerships in the success of such initiative in Hong Kong. Furthermore, we trace the 3 stages of the project - development, implementation, and competitive entrenchment - to identify the difficulties and challenges encountered and how these were overcome. By drawing some comparisons with the Singapore approach, we identify the kind of government involvement appropriate to spur on national competitiveness. We show that in building the NII, the dual aspects of private-sector leadership and government involvement are mutually reinforcing. Government intervention is necessary in creating the initial supply push, whereas the demand pull engendered by the market is critical for leveraging the NII as a platform for national competitiveness. The ramification of the study for other countries is discussed.published_or_final_versio

An in vitro Evaluation on a Novel Root Canal Cleansing Method by Using Nylon Fibers

Despite traditional metal-based dental files, such as NiTi being demonstrated effective in root cleaning, the tooth structure is always damaged. Thus, to fulfill the need for a minimally invasive tool for contemporary endodontics and dentistry, the use of polymer fibers might provide a good option, as it is soft, fabricable, and disposable. In this study, two types of nylon fibers with respective average diameters of 206.9 µm (fiber W) and 156.4 µm (fiber B), respectively, were used as dental files, and mounted onto either a reciprocating or a low-speed rotary hand-piece. In vitro, simulated root canal models were colored red using nail varnish, and then cleaned by the fiber files mounted on the hand-pieces. Three parts of the simulated models, i.e., the apical third, the medium third, and the coronal third, were chosen to assess the cleaning the efficiency (CE) of each specimen by calculating the ratio of the cross-sectional area changes, before and after cleansing, using micro-Computer Tomography (CT). A NiTi file with a low-speed hand-piece was used as a control. SEM was used to observe the nylon fiber surfaces before and after the cleansing. Micro-CT results showed that for both the nylon fibers, W and B, an average CE of 82.11% ± 9.68% for the medium third could be achieved, which is statistically higher (p < 0.01) than the coronal third and apical third. The cleansing efficiency was not affected by, the types of fibers, nor the hand-pieces according to student’s t-test. Most of the nylon fibers could withstand deformation after the cleansing. To conclude, nylon fiber files have demonstrated a certain cleansing efficiency in simulated root canals, and micro-CT is a promising method to assess CE.published_or_final_versio

Factors affecting communication in emergency departments: doctors and nurses’ perceptions of communication in a trilingual ED in Hong Kong

© 2015, Pun et al. Background: This study investigates clinicians’ views of clinician-patient and clinician-clinician communication, including key factors that prevent clinicians from achieving successful communication in a large, high-pressured trilingual Emergency Department (ED) in Hong Kong. Methods: Researchers interviewed 28 doctors and nurses in the ED. The research employed a qualitative ethnographic approach. The interviews were audio-recorded, transcribed, translated into English and coded using the Nvivo software. The researchers examined issues in both clinician-patient and clinician-clinician communication. Through thematic analyses, they identified the factors that impede communication most significantly, as well as the relationship between these factors. This research highlights the significant communication issues and patterns in Hong Kong EDs. Results: The clinician interviews revealed that communication in EDs is complex, nuanced and fragile. The data revealed three types of communication issues: (1) the experiential parameter (i.e. processes and procedures), (2) the interpersonal parameter (i.e. clinicians’ engagements with patients and other clinicians) and (3) contextual factors (i.e. time pressures, etc.). Within each of these areas, the specific problems were the following: compromises in knowledge transfer at key points of transition (e.g. triage, handover), inconsistencies in medical record keeping, serious pressures on clinicians (e.g. poor clinician-patient ratio and long working hours for clinicians) and a lack of focus on interpersonal skills. Conclusions: These communication problems (experiential, interpersonal and contextual) are intertwined, creating a complex yet weak communication structure that compromises patient safety, as well as patient and clinician satisfaction. The researchers argue that hospitals should develop and implement best-practice policies and educational programmes for clinicians that focus on the following: (1) understanding the primary causes of communication problems in EDs, (2) accepting the tenets and practices of patient-centred care, (3) establishing clear and consistent knowledge transfer procedures and (4) lowering the patient-to-clinician ratio in order to create the conditions that foster successful communication. The research provides a model for future research on the relationship between communication and the quality and safety of the patient safety

Characterization of a new polysiloxane-based titanium surface treatment for resin titanium bonding

PURPOSE: To characterize the polysiloxane-coated titanium surface with thermal treatment by XPS and AFM. Such a novel coating might significantly enhance resin bonding. METHODS AND MATERIALS: A layer (2mm) of silicone grease (Dow Corning Co., Michigan, USA) was applied on two titanium plates (Permascand, Ljungaverk, Sweden) followed by a thermal treatment at two temperatures, 800 and 1100 ◦C, respectively. Another titanium plate was surface treated by sandblasting. The atomic composition of titanium surfaces and change of chemical state…postprin

Herpetic shoulder paresis in a Chinese elderly patient

A patient with left shoulder girdle weakness secondary to herpetic myotomal paresis is reported. Needle electromyography revealed denervational discharge from the left supraspinatus, deltoid, and brachioradialis muscles, compatible with a radiculopathy that was relevant to his myotomes affected by zoster infection. The patient was managed with range-of-movement and strengthening exercises as well as pain relief for post-herpetic neuralgia. Further studies are required to determine whether antiviral treatment can limit the extent of motor deficit and hasten recovery. Zoster paresis should be one of the differential diagnoses of girdle muscle weakness.published_or_final_versio

Effectiveness of influenza vaccination in institutionalised older adults: a systematic review

This journal suppl. entitled: 19th Medical Research Conference; Department of Medicine, The University of Hong Kong, Queen Mary Hospital, Hong KongBACKGROUND: Influenza infection is common among institutionalised older adults. Many non-randomised observational studies on influenza vaccination suggested that it could reduce influenza-related hospitalizations and mortality in institutionalised older adults. Criticism regarding the effectiveness of influenza vaccine estimated by non-randomised observational studies includes the frailty selection bias and use of non-specific outcome like all-cause mortality. A systematic review of studies of influenza vaccination in institutionalized older adults to ...postprin

A Systematic Review of the Core Components of Language Learning Strategy Research in Taiwan

As the broader field of individual differences in second/foreign language learning has grown tremendously over the past few decades, its subfields have expanded with a similar intensity. Language learning strategies (LLS) is one such area. Developments have been made regarding the scope and methodology of LLS research, especially. While there have been a number of reviews of the field’s output, few have targeted research in a specific context. With this in mind, the current study offers a situated view of LLS research in Taiwan. It focuses on three core components that are essential to empirical research: (a) contexts and participant characteristics; (b) theoretical-conceptual aspects; and (c) methodological characteristics. Drawing on journal articles systematically collected from major databases and reviews conducted by multiple researchers to ensure reliability and to minimize bias, we provide an overview of the field as it has manifested in Taiwan. Findings from select studies are also discussed. In doing so, this article makes connections between LLS research in Taiwan and the larger, global context, with implications for "the road ahead." We hope it will be a valuable resource for anyone interested in reading about and/or conducting LLS research in this setting and others
