Leptotrichia hongkongensis sp. nov., a novel Leptotrichia species with the oral cavity as its natural reservoir

A straight, non-sporulating, Gram-variable bacillus (HKU24T) was recovered from the blood culture of a patient with metastatic breast carcinoma. After repeated subculturing in BACTEC Plus Anaerobic/F blood culture broth, HKU24T grew on brucella agar as non-hemolytic, pinpoint colonies after 96 h of incubation at 37 °C in an anaerobic environment and aerobic environment with 5% CO2. Growth was enhanced with a streak of Staphylococcus aureus. HKU24T was non-motile and catalase-negative, but positive for alkaline phosphatase, β-glucosidase, and α-glucosidase. It hydrolyzed phenylphosphonate and reduced resazurin. 16S rRNA, groEL, gyrB, recA, and rpoB sequencing showed that HKU24T occupies a distinct phylogenetic position among the Leptotrichia species, being most closely related to Leptotrichia trevisanii. Using HKU24T groEL, gyrB, recA, and rpoB gene-specific primers, fragments of these genes were amplified from one of 20 oral specimens. Based on phenotypic and genotypic characteristics, we propose a new species, Leptotrichia hongkongensis sp. nov., to describe this bacterium.

Orientations to Enrolment of Part-time Students: A classification system based upon students' perceived lifelong learning needs

This article develops a classification system for the orientations to enrolment of part-time students based upon their practical lifelong learning needs. Orientation to enrolment is seen as a complex construct embodying all the reasons, purposes, expectations and motivations that cause students to pick a particular course and elect to study by the part-time mode. Virtually all of the interviewed students had a vocational orientation so some previously used categorisation schemes were not suitable. Instead seven categories relating to lifelong learning needs provided a scheme which covered the cases and related well to explanations given by interviewees for enrolling in the courses. These were re-training or further development for those who need to make a career shift; education for professionals who need to undertake continuing professional development through their careers; an opportunity for a tertiary education for those who did not previously have the chance; an education at the tertiary level for those who did not do sufficiently well at school to qualify for direct entry to university; an alternative to mainstream education; education for adults; and learning for pleasure throughout the lifetime.     

Religious engagement and attitudes to the role of religion in society: their effect on civic and social values in an Asian context

This paper explored the impact of religious engagement (religious background, religious service attendance and religious activities participation) on adolescents’ civic and social values. Attitudes towards the influence of religion on society were investigated as a possible mediator/moderator of religious engagement. A model based on Western literature was tested using a sample of over 2000 Hong Kong students. Secondary data were drawn from the International Civics and Citizenship Education Study 2009. Multi-level modelling was used to assess individual and school level effects on civic and social values. Results indicated that religious engagement exerted varied effects. Religious background showed small and negative effects on students’ civic and social values. Participation in religious services indicated a small, positive and significant effect on social but not on civic values. Participation in religious activities showed no significant effect on either social or civic values. These variables exerted a small moderating effect on social and civic values through attitudes to the influence of religion on society. The latter exerted a positive and significant effect on civic values and a negative effect on social values. These results suggested that Western models depicting the positive relationship between religious engagement and citizenship values may not hold for Asian societies.

Changing Ideopolitical Emphases in Moral Education in China: An Analysis of the CCP Central Committee Documents

With the understanding that moral education is interpreted as both ideological and political education in China, this paper attempts to look at the ideopolitical emphases in government moral education documents since the adoption of the open policy in 1978. The analysis will be focused on three particular aspects, namely (1) the changing perception of the role of moral education, (2) the changing emphasis on what moral education should achieve, and (3) how such change of emphases would reflect the changing social and political circumstances in China. In sum, this paper argues that government documents on moral education can be a significant indicator for tracking social transition in China.     

寻索后后现代城市的灵性与正义

西方全球化发展,形成"受伤城市",后现代极端自由主义文化,形成自我中心主义(Egoism),引致城市精神文化与道德崩落.当代西方城市文化的困境,是马克思早年所谓的"异化"(alienation),城市建筑中,人都用铁窗、铁闸把自己锁在屋内,结果形成"枷锁城市"(carceral city).一个正义的城市,必须有义人传统,要解决当代城市这些问题,须了解城市是一个"他者共在的世界",由此寻索一个城市和谐文化的方向.蒲伯(Martin Buber)提出的"我一你"思想模式,关键就是要把"他者"视为一个完整的存在,人与人须建立一种真诚的关系.这人与他者间建立和谐关系的思想,在中国文化来说,就是"仁义"的理念.仁是人性中一种对"他者"的"感通",义则是正直合宜的行为.设计一个后后现代的城市,必须考虑一个文化的空间,建造一个有仁义感通的精神文化.     

Effect of terrain and building structures on the airflow in an airport

The aim of this study was to perform computational fluid dynamics (CFD) simulations on the airflows at the Hong Kong International Airport (HKIA). In particular, the effects of hangar buildings and terrain were studied to explore the effects of turbulence on flying aircraft, especially during landing. The CFD simulation showed that significant differences in wind speeds may occur between the north and the south runways on the western part of the HKIA under typhoon conditions with a strong north to northwesterly wind. Simulation also showed that the hanger buildings between the two runways on the western side and the nearby terrain could be causing the observed difference in the wind speeds. The results also indicated that these obstacles could cause significant wind speed variations at the western end of the south runway. This may affect the operation of landing aircraft. The CFD results for a typical typhoon case were analyzed and found to match the wind data recorded by an aircraft landing that day.     

Youth in a global world: attitudes towards globalization and global citizenship among university students in Hong Kong

Despite the wealth of theoretical literature on globalization and global citizenship, empirical studies on the topic are lacking, especially in the context of pedagogical needs in relation to global citizenship education. In order to address this gap, a study was conducted in Hong Kong to investigate the attitudes of university students towards various dimensions of globalization and global citizenship. The initial results indicate that Hong Kong university students are generally quite aware of globalization's impact on the economy and personal consumption choices and that while there is considerable apathy towards international affairs, there is also a great interest in cross-cultural service learning opportunities that is not being met by the available programmes. Moreover, this study finds almost no association between age, gender, and religion and any of the measured dependent variables on attitudes towards globalization and global citizenship, the only exception being the factor of past intercultural experiences, where a significant difference in measured attitudes was found between respondents who had and respondents who had not participated in such experiences before. Explanations of the findings and the implications of findings for policy and future research are discussed.
