To improve analytical thinking skills among college students, a course on ＂bioethics＂ was introduced and offered in two consecutive semesters to undergraduate students for which 245 students registered at each semester. The course was taught in the form of 14 lecture and discussion sessions, each for 95 minutes based on the content of A Cross-Cultural Introduction to Bioethics （2006） edited by Darryl Macer, and reviewed a wide variety of ethical and bioethical issues. In the next semester, the students received a similar teaching content that was rearranged to reflect the 15 universal principles of bioethics and human rights covered in the Bioethics Core Curriculum （2008）. Case studies were also added to each unit of the Core Curriculum with the support of the UNESCO＇s Asia Pacific Regional Office, Bangkok （Case Studies for Bioethics 2010）. To evaluate the results of teaching and to compare the achieved objectives between the two groups of students, a short questionnaire was given to all students who finished the course and took up the final written examination. In the whole, 454 students （225 in group I and 229 in group 2） completed the course and took the final examination and 427 （218 in group 1 and 209 in group 2） responded to the questionnaire which inquired into their interest in the discussion of bioethical issues： why they believed they were important, and what they had learned through them. The results of the questionnaire have been examined and compared to evaluate the success of ＂bioethics＂ in stimulating the interest and thinking ability of the students and enriching their experience of a cross-cultural discussion over bioethical issues using universal principles as general guidance. The result of this examination was so impressive that from 2011 bioethics has been formalized into the reformed curriculum of our international school.展开更多

However, some problems, including literary aphasia, objectified objectivism and de-contextualization, have revealed during our rethinking of Westernization, scientism and systematism, showing that we have been trapped by Western-centralism, scientism and post-colonialism. Faced with the demand from modem knowledge pattern of de-sinicization, de-contextualization and de-subjectification, we propose reconstruction strategies of re-sinicization and re-pragmatism in order to provide theoretical conception of rebuilding modem system for ancient literary theory study.展开更多

Thus, we will try to briefly elaborate on several tendencies about contemporary art in the Republic of Macedonia, by ＂screening＂ the theoretical discourses on the issue and by critical perception of recent practices concerning the field. Today＇s views on the creative practices, incorporated in ＂conceptual＂ packages that should develop a new culture of living, are manifested in the creative industries, have been just recently recognized in the Macedonian society. The ＂propaganda＂ character of the treatment of artistic practice changes only formally the media of their manifestations. The idea about the possible and necessary engaged attitude of art towards society had its place also in the modern as well in the postmodern concept of art. In the Republic of Macedonia this ＂ideological＂ attitude towards art regretfully has also become the main mechanism for political domination, manifested mainly in architecture and landscaping of public space. The commercialisation of art supported by the media imposes the discourses of popular art over the content of high art. It seems that art is represented in the field of ＂education and science＂ in the Republic of Macedonia only when certain pragmatic, frequently politicised, interests need to be satisfied.展开更多

Although there are several bibliometric studies based on citation analysis, very few have focused on research related to Traditional Chinese Medicine in China. METHODS: The bibliometric method used in this study included the following focuses: publication outputs for each year, paper type, language of publication, distribution of internationally collaborative countries, sources of funding, authorization number, distribution of institutes regarding collaborative publications, research fields, distribution of out-puts in journals, citation data, and h-index. RESULTS: A total of 3809 papers published from 1995 to 2012 were extracted from the science citation index(SCI). The cumulative number of papers from all six universities is constantly increasing. The United States attained the dominant position regarding complementary and alternative medicine research. The Chinese Academy of Sciences was the greatest participator in collaborative efforts. Research field analysis showed that the research mainly focused on pharmacology pharmacy, chemistry, integrative complementary medicine, plant sciences, and biochemistry molecular biology. The Shanghai University of Chinese Medicine had the most citations. CONCLUSION: In recent years, in terms of SCI papers, the six Traditional Chinese Medicine universities studied here have made great advances in scientific research.展开更多

The students＇ task was to participate as speakers in an international conference. Undergraduate students in a course of Business English at a small private university in western Mexico worked in teams to research and develop a topic to be sent as a proposal to the conference.The study used Interaction Analysis with a qualitative focus to observe participant interactions. Video and audio recordings were supplemented with participant interviews and questionnaires. Analysis shows that in the course of the project, the students learned not only business terminology, but also how to work together.展开更多

We monitored the comet from September 30 to November 4, 2010 and investigated the variation of activities. The Afp parameter derived from our r broadband data varies from 46.0 to 126.0 cm and increases with time. The dust production rate in terms of Afp was measured and a tentative calculation of the dust （or gas） loss-rate of nucleus was executed under the assumption that the nucleus of comet 103P/l-lartley 2 is spherical. The r-band image and the surface brightness profile taken on September 30, 2010 was measured and the gradient of surface brightness profile of 103P/Hartley 2 showed m 〈 -1.5,展开更多
