Oral Language Performance of Deaf and Hard-of-Hearing Students in Mainstream Schools.

J Deaf Stud Deaf Educ

October 2019

Centre for Sign Linguistics and Deaf Studies, The Chinese University of Hong Kong, Hong Kong Special Administrative Region.

In Hong Kong, students are expected to speak fluent Cantonese, Putonghua, and English. However, the curriculum does not include Cantonese studies, as children are expected to have already acquired Cantonese by the age of school entry. This study examined the language outcomes of Cantonese-speaking deaf or hard-of-hearing children who attend primary schools within the Hong Kong educational system and considered whether the system currently meets the needs of these children.

Electronic address:

Food waste is a low-cost and nutritious source of feed which could be beneficial to the fishery industry. The objective of this study was to use fermented food wastes as major sources of protein to replace the fish meal used in fish feeds for culturing jade perch (Scortum barcoo) and Nile tilapia (Oreochromis niloticus). Two experiments (a laboratory and a field trial) were conducted to test the suitability of the fish feeds for the two fish species.

Hypoxia is an important environmental stressor leading to endocrine disruption and reproductive impairment in fish. Although the hypoxia-inducible factor 1 (HIF-1) is known to regulate the transcription of various genes mediating oxygen homeostasis, its role in modulating steroidogenesis-related gene expression remains poorly understood. In this study, the regulatory effect of HIF-1 on the expression of 9 steroidogenic enzyme genes was investigated in zebrafish embryos using a "gain-of-function and loss-of-function" approach.

Understanding the microstructure and macrostructure of passages is important for reading comprehension. What cognitive-linguistic skills may contribute to understanding these two levels of structures has rarely been investigated. The present study examined whether some word-level and text-level cognitive-linguistic skills may contribute differently to the understanding of microstructure and macrostructure respectively.

Paddy soils and rice (Oryza sativa L.) contaminated by mixed heavy metals have given rise to great concern. Field experiments were conducted over two cultivation seasons to study the effects of steel slag (SS), fly ash (FA), limestone (LS), bioorganic fertilizer (BF), and the combination of SS and BF (SSBF) on rice grain yield, Cd, Pb, and Zn and nutrient accumulation in brown rice, bioavailability of Cd, Pb, and Zn in soil as well as soil properties (pH and catalase), at two acidic paddy fields contaminated with mixed heavy metals (Cd, Pb, and Zn).

Ni/Fe bimetallic nanoparticles were synthesized using biochar as a support (BC@Ni/Fe) and their effectiveness in removing BDE209 from soil was investigated. BET, SEM, TEM, XPS and FTIR were used to characterize the catalyst, and the efficiencies of biochar, Ni/Fe nanoparticles and BC@Ni/Fe for removing BDE209 from soil were compared. The results showed that Ni/Fe bimetallic nanoparticles highly dispersed in the biochar, reducing its agglomeration.

In vivo studies of the interactions of polybrominated diphenyl ethers (PBDEs) in plants have generally focused on uptake, translocation, metabolism and accumulation, but there were limited reports about the phytotoxicity and translocation of PBDEs in contaminated soil with the effects of nanoparticles. In this study, the effects of Ni/Fe bimetallic nanoparticles on translocation of polybrominated diphenyl ethers (PBDEs) in contaminated soil and its phytotoxicity to Chinese cabbage were investigated by soil culture experiments. The results showed that the plant biomass, germination rate, and shoot and root lengths of treated soil (S-5) increased by 0.

Environmental Engineering Program, Department of Civil Engineering, Auburn University, Auburn, AL, 36849, USA.

In this study, a kind of biochar-supported nano-hydroxyapatite (nHAP@BC) material was used in in-situ remediation of lead-contaminated soil. Column experiments were performed to compare the mobility of nHAP@BC and Bare-nHAP. The immobilization, accumulation and toxic effects of Pb in the after-amended soil were assessed by the in vitro toxicity tests and pot experiments.

The potential for nanoscale phosphate amendments to remediate heavy metal contamination has been widely investigated, but the strong tendency of nanoparticles to form aggregates limits the application of this technique in soil. This study synthesized a composite of biochar-supported iron phosphate nanoparticle (BC@Fe3(PO4)2) stabilized by a sodium carboxymethyl cellulose to improve the stability and mobility of the amendment in soil. The sedimentation test and column test demonstrated that BC@Fe3(PO4)2 exhibited better stability and mobility than iron phosphate nanoparticles.

Prior research has documented a relationship between narcissism and aggression but has focused only on dispositional narcissism without considering situational factors that may increase narcissism temporarily. This study explored the possibility that an increase in state narcissism would foster aggressive responding by increasing anger and hostile attributional bias following unexpected provocation among 162 college students from China. We created a guided-imagination manipulation to heighten narcissism and investigated its effects on anger, aroused hostile attribution bias, and aggressive responses following a provocation with a 2 (narcissism/neutral manipulation) × 2 (unexpected provocation/positive evaluation condition) between-subjects design.

Plastic waste in the marine environment: A review of sources, occurrence and effects.

Sci Total Environ

October 2016

Department of Science and Environmental Studies, The Hong Kong Institute of Education, Hong Kong.

This review article summarises the sources, occurrence, fate and effects of plastic waste in the marine environment. Due to its resistance to degradation, most plastic debris will persist in the environment for centuries and may be transported far from its source, including great distances out to sea. Land- and ocean-based sources are the major sources of plastic entering the environment, with domestic, industrial and fishing activities being the most important contributors.

August 2016

Environmental Engineering Program, Department of Civil Engineering, Auburn University, Auburn, AL, 36849, USA.

This paper was aimed to study the impact of "ageing" (aged in non-saturated soil for 2 and 4 weeks prior to exposure) nanoscale zero-valent iron (nZVI) on the terrestrial plant. The effects of nZVI on Oryza Sativa germination, seedlings growth, chlorophyll biosynthesis, oxidative stress and the activities of antioxidant enzymes at low (250 mg/kg) and high (1000 mg/kg) concentrations were investigated in this study. The results showed that neither the freshly added nor the "ageing" nZVI to the soil had a significant effect on germination, regardless of concentration.

September 2016

Department of Science and Environmental Studies, The Hong Kong Institute of Education, Hong Kong. Electronic address:

A photoresponsive surface molecularly imprinted polymer for uric acid in physiological fluids was fabricated through a facile and effective method using bio-safe and biocompatible ZnO nanorods as a support. The strategy was carried out by introducing double bonds on the surface of the ZnO nanorods with 3-methacryloxypropyltrimethoxysilane. The surface molecularly imprinted polymer on ZnO nanorods was then prepared by surface polymerization using uric acid as template, water-soluble 5-[(4-(methacryloyloxy)phenyl)diazenyl]isophthalic acid as functional monomer, and triethanolamine trimethacryl ester as cross-linker.
