Science Letters:Discovery of ultrahigh-T spinel-garnet granulite with pure CO_2 fluid inclusions from the Altay orogenic belt, NW China

We first report discovery of the spinel-garnet-orthopyroxene granulite with pure CO2 fluid inclusions from the Fuyun region of the late Paleozoic Altay orogenic belt in Central Asia, NW China. The rock is characterized by an assemblage of garnet, orthopyroxene, spinel, cordierite, biotite, plagioclase and quartz. Symplectites of orthopyroxene and spinel, and orthopyroxene and cordierite indicate decompression under UHT conditions. Mineral chemistry shows that the or-thopyroxenes have high XMg and A12O3 contents (up to 9.23 wt%). Biotites are enriched in TiO2 and XMg and are stable under granulite facies conditions. The garnet and quartz from the rock carry monophase fluid inclusions which show peak melting temperatures of around -56.7℃, indicating a pure CO2 species being presented during the ultrahigh-T metamorphism in the Altay orogenic belt. The inclusions homogenize into a liquid phase at temperatures around 15.3-23.8℃ translating into CO2 densities of the order of 0.86-0.88 g/cm3. Based on prelim     

西部大开发与农村教育发展的走向

农村教育是困扰中国农村三大难题之一。西部大开发给了农村教育从低层次单一性走向各级、各类、各层次教育全面发展的必要与可能,建议采取“在教育事业发展基础上以提高教育质量为目标的战略取向”。农村教育告别“工具论”,走向“主体论”,其重要标志是看能否以“把教育公正与公平放在首位”作为教育发展价值的最大化;其科学方式是通过信息技术教育实现跨越式发展;其前提是建立贫困地区农村义务教育投入的保证机制。     

论伏尔泰与孟德斯鸠中国观的主要分歧

伏尔泰与孟德斯鸠中国观的主要分歧在于:中国是开明君主制国家还是专制国家;中国的伦理道德是理想社会的基础还是专制暴政的纠偏器;中国人的品行是诚实有礼的还是狡诈的。伏尔泰和孟德斯鸠对中国问题的不同看法,是由他们各自的政治观点和学术立场决定的。     

Chinese gay men’s coming out narratives: Connecting social relationship to co-cultural theory

Theorizing the intersection of queer identity and culture values, this study examines Chinese gay men’s coming-out experiences through a narrative analysis of 60 self-reported stories online. It finds that Chinese gay men’s decision to come out, their communication orientations, and the outcomes of their coming out are influenced by traditional Chinese cultural values such as family, marriage, and duty. Assertive assimilation, assertive accommodation, and nonassertive accommodation are the most used communication orientations. The study adds to co-cultural theory by demonstrating that types of social relationships affect the communication orientations adopted, at least in the context of China.     

A U.S.-Chinese Comparison of Affectionate Communication in Parent-Child Relationships

Affectionate communication is central to the maintenance of relational closeness, but it is also subject to relational, contextual, and cultural factors. This study was designed to examine the cultural effects on affectionate communication in parent-child relationships in the United States and China. Results indicated that Chinese fathers and mothers expressed less verbal, nonverbal, and supportive affection to their children than American parents. Both Chinese and American parents expressed affection to their children more through supportive behaviors than through verbal and nonverbal behaviors. In both cultures, mothers engaged in more verbal, nonverbal, and supportive affection with their children than fathers.

回归后的香港新诗创作

20世纪90年代以来的香港诗坛并未因九七回归导致香港新诗主体性的消失和创作自由的失落,反而由于有“艺术发展局”的资助,诗刊、诗集的出版显得更加丰富多元。在诗体建设方面,颂歌的勃兴和散文诗的崛起,是最值得重视的现象。“立足香港,胸怀祖国,放眼世界”的香港新诗,就这样以自由的独特风姿屹立在新世纪的两岸四地诗坛中。
