A detailed rock density model of the Hong Kong territories

We used the geological map and published rock density measurements to compile the digital rock density model for the Hong Kong territories.We then estimated the average density for the whole territory.According to our result,the rock density values in Hong Kong vary from 2101 to 2681 kg·m^(-3).These density values are typically smaller than the average density of 2670 kg·m^(-3),often adopted to represent the average density of the upper continental crust in physical geodesy and gravimetric geophysics applications.This finding reflects that the geological configuration in Hong Kong is mainly formed by light volcanic formations and lava flows with overlying sedimentary deposits at many locations,while the percentage of heavier metamorphic rocks is very low(less than 1%).This product will improve the accuracy of a detailed geoid model and orthometric heights.

A Comparative Study of the L2 Pragmatic Competence of University Students in Hong Kong and the Chinese Mainland:The Contributions of Sociocultural Context and Linguistic Proficiency

This study investigates the differences in pragmatic competence between Hong Kong and Chinese mainland university students.Participants included 19 native speakers of English,115 Chinese mainland students,divided into those who had spent time abroad in an English-speaking country(CM A)and those who had not(CM NA),and 97 Hong Kong students,divided into those from an English-medium secondary school(Hong Kong EMI)and those from a Chinese-medium school(Hong Kong CMI).Linguistic proficiency was measured by a C-test,and pragmatic competence by a Metapragmatic Knowledge Test,an Irony Test and a Monologic Role Play.Group scores were compared using ANCOVAs to control for differences in proficiency.The results point to a continuum of pragmatic competence—EMI>CMI>CM A>CM NA—reflecting the groups’access to English in real-life contexts.The differences between the Hong Kong groups and the Chinese mainland groups were clearest in those tests measuring processing capacity(i.e.,Irony Response Time and the Monologic Role Play).CM A,but not CM NA,performed as well as the Hong Kong groups on measures of metapragmatic awareness.The results are discussed in terms of Bialystok’s(1993)distinction between analyzed representation and control of processing.

Using Five Music Instructional Methods to Illustrate the Social Constructive Music Teaching Framework in Hong Kong Primary Level Music Education

Music education under the frame name of arts education has been integrated into the primary and secondary education curriculums in Hong Kong for more than 20 years,starting from 2001,the year of launching the Learning to Learn curriculum for the reconstruction of the education system for the younger generation.Music education,embedded into the arts education,was therefore regarded as one of the key subjects to cultivate and uplift student holistic development,focusing on aesthetic skill training and moral growth development.This research was an exploration study of music teaching practices from two private international and two general public school music teachers at the primary school level.The value of this study rested on borrowing the idea of Shulman’s pedagogical content knowledge(PCK)principle to create a social constructivist music teaching framework from five commonly-used instructional methods,namely,Orff,Kodaly,Dalcrozes,Suzuki,and Gordon’s approaches.Based on the evaluations of these four case studies,hypotheses on the differences in the PCK were tested with the types of schools and found to be no difference.The preliminary results suggested that music teachers in private international schools had similar pedagogical approaches to music instruction to teachers in aided-public schools.Additionally,the modeling,guiding,and training approach was identified as a grounded teaching method for music education at the primary school level regardless of different types of schools.Other implications like the further development of the framework were discussed.

Anti-inflammatory effects of Tao Hong Si Wu Tang in mice with lung cancer and chronic obstructive pulmonary disease

BACKGROUND Lung cancer(LC)combined with chronic obstructive pulmonary disease(COPD)is a common combination of comorbidities.Anti-inflammation and modulation of oxidative/antioxidative imbalance may prevent COPD-induced LC,and are also crucial to the treatment of LC combined with COPD.Modern studies have shown that Tao Hong Si Wu Tang(THSW)has vasodilatory,anti-inflammatory,anti-fatigue,anti-shock,immunoregulatory,lipid-reducing,micronutrient-supplementing,and anti-allergy effects.AIM To observe the effects of THSW on COPD and LC in mice.METHODS A total of 100 specific pathogen-free C57/BL6 mice were randomly divided into five groups:Blank control group(group A),model control group(group B),THSW group(group C),IL-6 group(group D),and THSW+IL-6 group(group E),with 20 mice in each group.A COPD mouse model was established using fumigation plus lipopolysaccharide intra-airway drip,and an LC model was replicated by in situ inoculation using the Lewis cell method.RESULTS The blank control group exhibited a clear alveolar structure.The model control and IL-6 groups had thickened alveolar walls,with smaller alveolar lumens,interstitial edema,and several inflammatory infiltrating cells.Histopathological changes in the lungs of the THSW and THSW+IL-6 groups were less than those of the model control group.The serum IL-1β,IL-6,and TNF-αlevels and IL-6R,JAK,p-JAK,STAT1/3,p-STAT1/3,FOXO,p-FOXO,and IL-7R expression levels in lung tissues of mice in the rest of the groups were significantly higher than those of the blank control group(P<0.01).Compared with the model control group,the IL-6 group demonstrated significantly higher levels for the abovementioned proteins in the serum and lung tissues(P<0.01),and the THSW group had significantly higher serum IL-1β,IL-6,and TNF-αlevels and IL-7R expression levels in lung tissues(P<0.01)but significantly decreased IL-6R,JAK,p-JAK,STAT1/3,p-STAT1/3,FOXO,p-FOXO,and IL-7R levels(P<0.01).CONCLUSION THSW reduces the serum IL-1β,IL-6,and TNF-αlevels in the mouse model with anti-inflammatory effects.Its antiinflammatory mechanism lies in inhibiting the overactivation of the JAK/STAT1/3 signaling pathway.

Drivability of Large Diameter Steel Cylinders During Hammer-Group Vibratory Installation for the Hong Kong–Zhuhai–Macao Bridge

The Hong Kong–Zhuhai–Macao Bridge(HZMB)involved the installation of 120 mega-cylinders with a diameter of 22 m,weights up to 513 t,and penetration depths up to 33 m using an eight-vibratory hammer group.Due to the lack of engineering experience on the drivability of large-diameter cylinders under multiple vibratory hammers,predicting the penetration rate and time of steel cylinders is an open challenge that has a considerable impact on the construction control of the HZMB.In this study,the vibratory penetration of large-diameter steel cylinders in the HZMB is investigated based on geological surveys,field monitoring,and drivability analysis.The vibratory penetration rate,installation accuracy,and dynamic responses of the steel cylinders at both the eastern and western artificial islands are analyzed.The dynamic soil resistance has a great influence on the cylinder drivability.However,the current design methods for estimating the vibratory driving soil resistance are proven inaccurate without considering the scale effects.Therefore,a modified method with a normalized effective area ratio A_(r,eff)is proposed in this study to calculate the vibratory soil resistance for open-ended thin-wall cylinders under unplugged conditions.Considering the scale effects on the vibratory driving soil resistance,the proposed method leads to closer results to the measured data,providing a reference for future engineering practice.

Predicting Carpark Prices Indices in Hong Kong Using AutoML

The aims of this study were threefold:1)study the research gap in carpark and price index via big data and natural language processing,2)examine the research gap of carpark indices,and 3)construct carpark price indices via repeat sales methods and predict carpark indices via the AutoML.By researching the keyword“carpark”in Google Scholar,the largest electronic academic database that coversWeb of Science and Scopus indexed articles,this study obtained 999 articles and book chapters from 1910 to 2019.It confirmed that most carpark research threw light on multi-storey carparks,management and ventilation systems,and reinforced concrete carparks.The most common research method was case studies.Regarding price index research,many previous studies focused on consumer,stock,press and futures,with many keywords being related to finance and economics.These indicated that there is no research predicting carpark price indices based on an AutoML approach.This study constructed repeat sales indices for 18 districts in Hong Kong by using 34,562 carpark transaction records from December 2009 to June 2019.Wanchai’s carpark price was about four times that of Yuen Long’s carpark price,indicating the considerable carpark price differences inHong Kong.This research evidenced the features that affected the carpark price indices models most:gold price ranked the first in all 19 models;oil price or Link stock price ranked second depending on the district,and carpark affordability ranked third.

Effects of Manganese on the Antioxidant System and Related Gene Expression Levels in the “Hong Yang” Kiwifruit Seedlings

To explore how manganese affects the antioxidant system and the expression levels of related genes of“Hong yang”seedlings,the leaves of its tissue cultured seedlings were taken as test materials,and single factor treatment was performed by changing the manganese chloride(MnCl_(2)·4H_(2)O)solution concentration when spraying the leaves.The expression levels of Mn-SOD,POD64 and POD27 genes in leaves were quantitatively analyzed by real-time quantitative PCR(qRT-PCR)at different determination times.Meanwhile,the contents of malondial-dehyde(MDA),hydrogen peroxide(H_(2)O_(2)),the activities of antioxidant enzymes,including catalase(CAT),peroxidase(POD),and superoxide dismutase(SOD).The results showed that the SOD,CAT,POD,ascorbate peroxidase(APX),and reduced glutathione(GSH)activities in leaves were the highest at 12 h post-treatment with 50μM MnCl_(2)·4H_(2)O.Furthermore,the contents of MDA and H_(2)O_(2) in leaves also peaked when the concentration of H_(2)O_(2) is 50μM,which is the minimum value.Additionally at 50μM Mn^(2+),the Mn-SOD and POD27 expression was up-regulated as compared to the control,which promoted the expression of their respective enzyme activities.However,POD64 expression increased with the increasing Mn^(2+) concentration.Therefore,50μM is the optimal concentration of Mn when exogenously applied on“Hong yang”,which improve the antioxidant enzyme activity and regulate the plant’s physiological and biochemical functions.
