Group effects on individual attitudes toward social responsibility
No full textThis study uses a quasi-experimental design to investigate what happens to individual socially responsible attitudes when they are exposed to group dynamics. Findings show that group engagement increases individual attitudes toward social responsibility. We also found that individuals with low attitudes toward social responsibility are more likely to change their opinions when group members show more positive attitudes toward social responsibility. Conversely, individuals with high attitudes do not change much, independent of group characteristics. To better analyze the effect of group dynamics, the study proposes to split social responsibility into relative and absolute components. Findings show that relative social responsibility is correlated with but different from absolute social responsibility although the latter is more susceptible than the former to group dynamics
Electricity consumption in Hong Kong: trend analysis and greenhouse gases emission
No full textThe consumption of electricity has increased continuously in the past four decades. Inevitably, the emission of greenhouse gases has increased in the same period even though Hong Kong’s power companies have produced a certain percentage of electricity using “cleaner” fuels such as natural gas and nuclear power in recent years. This paper presents a four-parameter logistic model (To WM, Lai TM, Lo WC, Lam KH, Chung WL. The growth pattern and fuel life cycle analysis of the electricity consumption of Hong Kong. Environ Pollut. 2012;165:1–10) that describes the growth pattern of Hong Kong’s overall electricity consumption. The same approach was used to model the sectoral electricity consumption in Hong Kong. In addition, a fuel life cycle analysis was used to determine greenhouse gases emission due to electricity consumption. It was found that the emission factor due to the electricity generated in Hong Kong was 0.824 kg CO2-equivalent per kWh while the emission factor due to the electricity consumed in Hong Kong was 0.751 kg CO2-equivalent per kWh, as 23% of the electricity consumed was imported (net import) from the Daya Bay Nuclear Power Plant located in Shenzhen in 2012. Future electricity demand is presented
Education and Society in Hong Kong and Macao: Comparative Perspectives on Continuity and Change
No full textHong Kong and Macao have much in common. The dominant populations in both territories are Cantonese-speaking Chinese; both are small in area; both are urban societies; both have been colonies of European powers; and both have undergone political transition to reunification with China. Yet in education, for reasons that are analysed in this book, they are very different.
The patterns of similarities and differences in the two territories make a fascinating basis for comparative study. The overarching theme of the book, on continuity and change, is particularly pertinent following the transition of the two societies to the postcolonial era.
This thoroughly-revised and expanded second edition builds on the widely-recognised first edition. The work has been acclaimed as a significant contribution to the broad field of comparative education as well as to study of the specific societies which are its main focus.
Mark Bray is Chair Professor of Comparative Education at the University of Hong Kong. Ramsey Koo is a Senior Lecturer at the Hong Kong Institute of Education. Both have long experience of research on education in Hong Kong and Macao; and both are active in professional societies concerned with comparative education
Construction of Hong-dae cultural district : cultural place, cultural policy and cultural politics
Full text linkCho M. Construction of Hong-dae cultural district : cultural place, cultural policy and cultural politics. Bielefeld (Germany): Bielefeld University; 2007.This dissertation examines how the process of creating the "Hong-dae cultural district" in Seoul has involved the mobilisation of various social groups and triggered the (re)institutionalisation of the meaning of "the cultural". It seeks to explicate how a cultural policy project can stimulate the emergence of social groups, which challenge existing policy provisions and laws and lead to the (re)institutionalisation of "Hong-dae culture". In so doing, the author will be able to simultaneously take account of the issues of agency, structure and culture by explicating the relationship between cultural policy and social change

Synthesis optimization and charge carrier transfer mechanism in LiLuSiO<sub>4</sub>:Ce, Tm storage phosphor
No full textLiLuSiO4:Ce and LiLuSiO4:Ce, Tm show very efficient charge carrier storage properties upon beta irradiation after samples have received treatment in vacuum. They outperform the commercial storage phosphor BaFBr(I):Eu2+ in many aspects. The influence of the synthesis conditions, Ce and Tm concentration, nonstoichiometry and codoping with Ca, Hf, Al and Ge are reported. Based on the results of the synthesis optimization, thermoluminescence (TL) emission and TL excitation spectra a mechanism of charge carrier transfer, storage, and recombination during irradiation and thermal or optical readout is proposed.Accepted Author ManuscriptRST/Fundamental Aspects of Materials and EnergyRST/Luminescence Material
Urban Heat Island Analysis Using the Landsat TM Data and ASTER Data: A Case Study in Hong Kong
No full textIn this paper, the effect of urban heat island is analyzed using the Landsat TM data and ASTER data in 2005 as a case study in Hong Kong. Two algorithms were applied to retrieve the land surface temperature (LST) distribution from the Landsat TM and ASTER data. The spatial pattern of LST in the study area is retrieved to characterize their local effects on urban heat island. In addition, the correlation between LST and the normalized difference vegetation index (NDVI), the normalized difference build-up index (NDBI) is analyzed to explore the impacts of the green land and the build-up land on the urban heat island by calculating the ecological evaluation index of sub-urban areas. The results indicate that the effect of urban heat island in Hong Kong is mainly located in three sub-urban areas, namely, Kowloon Island, the northern Hong Kong Island and Hong Kong International Airport. The correlation between LST and NDVI, NDBI also indicates that the negative correlation of LST and NDVI suggests that the green land can weaken the effect on urban heat island, while the positive correlation between LST and NDBI means that the built-up land can strengthen the effect of urban heat island in our case study. Although satellite data (e.g., Landsat TM and ASTER thermal bands data) can be applied to examine the distribution of urban heat islands in places such as Hong Kong, the method still needs to be refined with in situ measurements of LST in future studies
