Availing ourselves of this opportunity, we sincerely wish our readers a happy and prosperous New Year! China International Studies began its publication last December. Since its inception, various think-tanks and institutions of higher learning both at home and abroad as well as Chinese embassies in foreign countries and foreign embassies in Beijing have offered it great support. Many readers wrote to us giving their encouragement on this new-born publication. We are carrying some of the messages in this issue to express our deep appreciation. Articles in this issue are mainly on the Middle East situation, the Iran nuclear issue, China-EU relations, China-India relations and China’s peaceful diplomacy. We are also publishing a paper by a foreign scholar for the first time.展开更多

Furthermore, it is still a country where international relations are under the umbrella of political science and political science itself is heavily influenced by the study of the law. This paper looks at the development of international relations both as a tool for training diplomats and as a topic of study within political science in Chile. It does so within the framework of the social sciences. Using interviews as a complimentary tool of research, it concludes that, along with a marked influence of economics in the study of social sciences in Chile, the country's political and social history has shaped the advent of social sciences at the undergraduate level and has dwarfed the growth and contents of both political science and international studies, in spite of the country's successful embrace of globalization.展开更多

The aim of the study was to investigate whether International Study Experiences (ISE) in other countries during basic nursing education had an impact on newly graduated nurses as regards to self-reported competence. Moreover, a second aim was to explore what background factors that facilitated or constituted a hindrance for nursing students to choose to conduct part of their basic nursing education abroad. At 11 Universities/University Colleges (henceforth called Higher Education Institutions [HEIs]) in Sweden, 565 nursing students responded to the Nurse Professional Competence (NPC) Scale. Students with ISE rated their competence significantly higher on three NPC competence areas—“Legislation in nursing and safety planning”, “Leadership and development of nursing” and “Education and supervision of staff/students”. Background factors that significantly seemed to enhance ISE were living alone, not having children or other commitments in relation to family, international focus at the HEI and previous international experience. Lack of financial means was reported to prevent students from choosing ISE. The study implies that several background factors are of importance whether students choose ISE or not. ISE during basic nursing education might result in better self-reported competence in leading and developing nursing care, including education of future nurses, and in providing safe care.展开更多

Key variables that may influence stillbirth, early neonatal, perinatal and infant mortality rates in BC and Finland were studied. Methods: After standardizing definitions, data for all births between 2001 and 2009 from provincial and national registries were used to compare perinatal outcomes between BC and Finland. Annual change was evaluated with regression analyses. Results: Births before 22 weeks gestation were excluded. All mortality rates per 1000 were lower in Finland vs BC (perinatal: 5.1 vs 6.2, stillbirth: 3.4 vs 3.9, early neonatal 1.7 vs 2.4, infant 2.9 vs 4.0;all p Higher multiple birth and preterm birth rates in BC are affecting mortality rates. Finland’s policy of single embryo transfer is a potential explanation. It is possible to have good perinatal outcomes and low caesarean section rates. Conclusions: The Finnish health care system may suggest possible solutions for improved perinatal outcomes. Lower per capita health care expenditures in Finland do not appear to have adversely affected perinatal outcomes.展开更多

It is also a process to await the Fourth World Conference on Women to be held in Beijing in 1995, a process to further mobilize women from various countries to gain equality between the sexes and to take a part in social development. The second international seminar on women’s studies was held from November 23 to 26, 1993, at Beijing University in preparation for this day. Some 100 women researchers from Australia, Bangladesh’, Canada, the United States, England, Malaysia and Japan, as well as Hong Kong and China participated in the event. It was one of the most lively and active seminars held during this process. To take prompt action in development was a common nderstanding of the participants.展开更多

Life span studies on carcinogenesis. Pacific Northwest Laboratory observed 3782 rats given a single inhalation of 239Pu O2 at initial lung burden ranging from 0.25 to 180 nCi. Significant life span shortening was found at lung dose > 8 Gy and it was indicated that the presence of a 'possible' threshold of about 1 Gy for lung tumor formation. 2. Health effects of radon and its progeny. Both experimental and epidemiological survey were studied. The nominal probability coefficient (fatality) for the public and workers are 7.90×105 per mJhm-3 (2.77 ×10~4 per working level month, WLM). 3. Health effects of 3H on postnatal brain development and neurobehavior, genetic effects, carcinogenic effects and adaptive effects of 3H were investigated. 4. Study on the effects of neuroendocrine system under low level irradiation of 75Se (Auger electron emitter) and 35S (β-particles emitter). The results showed that the neuroendocrine system is very sensitive to small dose of internal irradiation.展开更多
