In order to enhance Hong Kong non-Chinese speaking (NCS) students’ ability to learn practical writing and presenting ideas appropriately in Chinese, Dr. Mark Shum Shiu Kee’s research team received funding from the Hong Kong Education Bureau to develop Chinese practical writing teaching materials for NCS students in 2016/17. This paper describes how the researchers develop these teaching materials by adopting Functional Grammar Theory, and investigates the effectiveness of the teaching material package at equipping the NCS students’ with ability in using function words. This paper aims at exploring how effective the newly developed practical writing teaching material package at enhancing NCS students’ ability to use function words is. With reference to the Systemic Functional Linguistic (SFL) Theory, Chinese practical writing teaching material package suitable for NCS students was developed. The package reading materials were developed by looking into the communicative function, schematic structure and metalanguage of different genres. Besides, NCS students’ difficulty in using function words and expressions of different genres were also analyzed. By referring to “Genre Function” theory and “Reading to Learn” pedagogy, interactive exercises that combine reading and writing were designed. These suggested exercises guide students to learn in a process, from deconstruction of the sample texts to joint construction and individual construction. Apart from the above, frontline Chinese language teachers were invited to conduct tryout sessions to test the effectiveness of the teaching material package. The analysis of students’ writings in pre-tests and post-tests, together with the research data from teachers and students interviews, provide a comprehensive evaluation on the effectiveness of the practical writing teaching material package. Feasible suggestions for enhancing NCS students’ ability, particularly in using function words and constructing practical writing, are provided for teaching NCS students to construct practical writing.

Tuned liquid column dampers with adaptive tuning capacity for structural vibration control

Shum, K.M.,Xu, Y.L. Techno-Press 2005 Structural Engineering and Mechanics, An Int'l Jou Vol.20 No.5

The natural frequencies of a long span bridge vary during its construction and it is thus difficult to apply traditional tuned liquid column dampers (TLCD) with a fixed configuration to reduce bridge vibration. The restriction of TLCD imposed by frequency tuning requirement also make it difficult to be applied to structure with either very low or high natural frequency. A semi-active tuned liquid column damper (SATLCD), whose natural frequency can be altered by active control of liquid column pressure, is studied in this paper. The principle of SATLCD with adaptive tuning capacity is first introduced. The analytical models are then developed for lateral vibration of a structure with SATLCD and torsional vibration of a structure with SATLCD, respectively, under either harmonic or white noise excitation. The non-linear damping property of SATLCD is linearized by an equivalent linearization technique. Extensive parametric studies are finally carried out in the frequency domain to find the beneficial parameters by which the maximum vibration reduction can be achieved. The key parameters investigated include the distance from the centre line of SATLCD to the rotational axis of a structure, the ratio of horizontal length to the total length of liquid column, head loss coefficient, and frequency offset ratio. The investigations demonstrate that SATLCD can provide a greater flexibility for its application in practice and achieve a high degree of vibration reduction. The sensitivity of SATLCD to the frequency offset between the damper and structure can be improved by adapting its frequency precisely to the measured structural frequency.

Optimum LCVA for suppressing harmonic vibration of damped structures

Shum, K.M.,Xu, Y.L.,Leung, H.Y. Techno-Press 2017 Smart Structures and Systems, An International Jou Vol.20 No.4

Explicit design formulae of liquid column vibration absorber (LCVA) for suppressing harmonic vibration of structures with small inherent structural damping are developed in this study. The developed design formulae are also applicable to the design of a tuned mass damper (TMD) and a tuned liquid column damper (TLCD) for damped structures under harmonic force excitation. The optimum parameters of LCVA for suppressing harmonic vibration of undamped structures are first derived. Numerical searching of the optimum parameters of tuned vibration absorber system for suppressing harmonic vibration of damped structure is conducted. Explicit formulae for these optimum parameters are then obtained by a series of curve fitting techniques. The analytical result shows that the control performance of TLCD for reducing harmonic vibration of undamped structure is always better than that of non-uniform LCVA for same mass and length ratios. As for the effects of structural damping on the optimum parameters, it is found that the optimum tuning ratio decreases and the optimum damping ratio increases as the structural damping is increased. Furthermore, the optimum head loss coefficient is inversely proportional to the amplitude of excitation force and increases as the structural damping is increased. Numerical verification of the developed explicit design expressions is also conducted and the developed expressions are demonstrated to be reasonably accurate for design purposes.

Buffeting response control of a long span cable-stayed bridge during construction using semi-active tuned liquid column dampers

Shum, K.M.,Xu, Y.L.,Guo, W.H. Techno-Press 2006 Wind and Structures, An International Journal (WAS Vol.9 No.4

The frequency of a traditional tuned liquid column damper (TLCD) depends solely on the length of liquid column, which imposes certain restrictions on its application to long span cable-stayed bridges during construction. The configuration of a cable-stayed bridge varies from different construction stages and so do its natural frequencies. It is thus difficult to apply TLCD with a fixed configuration to the bridge during construction or it is not economical to design a series of TLCD with different liquid lengths to suit for various construction stages. Semi-active tuned liquid column damper (SATLCD) with adaptive frequency tuning capacity is studied in this paper for buffeting response control of a long span cable-stayed bridge during construction. The frequency of SATLCD can be adjusted by active control of air pressures inside the air chamber at the two ends of the container. The performance of SATLCD for suppressing combined lateral and torsional vibration of a real long span cable-stayed bridge during construction stage is numerically investigated using a finite element-based approach. The finite element model of SATLCD is also developed and incorporated into the finite element model of the bridge for predicting buffeting response of the coupled SATLCD-bridge system in the time domain. The investigations show that with a fixed container configuration, the SATLCD with adaptive frequency tuning can effectively reduce buffeting response of the bridge during various construction stages.

Spaceborne Gravity Sensors for Continental Hydrology and Geodynamic Studies

Shum C. K.,Han Shin-Chan,Braun Alexander The Korean Society of Remote Sensing 2005 大韓遠隔探査學會誌 Vol.21 No.1

The currently operating NASA/GFZ Gravity Recovery and Climate Experiment (GRACE) mission is designed to measure small mass changes over a large spatial scale, including the mapping of continental water storage changes and other geophysical signals in the form of monthly temporal gravity field. The European Space Agency's Gravity field and steady state Ocean Circulation Explorer (GOCE) space gravity gradiometer (SGG) mission is anticipated to determine the mean Earth gravity field with an unprecedented geoid accuracy of several cm (rms) with wavelength of 130km or longer. In this paper, we present a summary of present GRACE studies for the recovery of hydrological signals in the Amazon basin using alternative processing and filtering techniques, and local inversion to enhance the temporal and spatial resolutions by two-folds or better. Simulation studies for the potential GRACE detection of slow deformations due to Nazca-South America plate convergence and glacial isostatic adjustment (GIA) signals show that these signals are at present difficult to detect without long-term data averaging and further improvement of GRACE measurement accuracy.

The Effect of Chinese Subsidiary Manager's Dual Organizational Identification on Intra-firm Vertical Knowledge Flow

Shum Sze Ching,Eon-Seong Lee 한국무역통상학회 2020 무역통상학회지 Vol.20 No.3

Organizational identification is a well-known topic in the field of human resources, but it has not commanded much research in the context of multinational corporations. Subsidiary managers act as boundary spanners and are, thus, likely to develop a dual organizational identification. This study aimed to examine the pattern of Chinese subsidiary managers’ organization identification and test how dual organizational identification affect the degree and direction of knowledge flow. A survey was conducted on China subsidiary managers. Managers were grouped into high comparable, disparate with subsidiary-oriented identification, disparate with MNC-oriented identification, and low comparable levels of dual organizational identification. Results confirmed the dual organizational identification of Chinese subsidiary managers and its effect on the degree and direction of knowledge flow. Results provided critical insight to international human resources management.
