杜甫诗歌所叙唐代陇蜀荆湘气候特征   总被引:1,自引:0,他引:1  
杜甫诗歌具有广义的史学价值。杜甫晚年飘泊诗作的相关描述,较为真实而又全面地反映了唐代陇、蜀、荆、湘沿途城市的气候特征。唐代秦州秋阳杲杲,秋雨迷蒙,秋霜凛冽,秋月凄清,同谷岁暮则雨多雪盛,偶见冬虹;成都四季分明,冷热适中,然时有春旱、夏洪发生;夔州夏秋毒热,巫山雾瘴、云雨、霜雪、雷电变幻莫测;荆州及湖湘东南一带春季早暖,夏季酷热多雨、易发洪水,秋季前热后凉,冬季冷热不均。唐代陇、蜀、荆、湘沿途城市的气候与今天上述各地情况基本相符,杜甫夏秋叹热莫过于夔州与潭州,亦与今天的重庆和长沙同列全国“火炉”城市地位相当。另据杜诗所叙剑门蜀道腊月山花开放,通泉冬季蚊蚋活跃,成都四月黄梅成熟,戎州、泸州六月盛产荔枝,江陵正月嫩荷抽叶、飞燕营巢,潭州正月蜂鸣密林、燕舞江滨,湘潭二月南风蒸地、春热黄昏等情况,唐代陇、蜀、荆、湘一带的年平均气温似应高于今天。  相似文献

Although there is a fairly extensive literature on social and educational inclusion of individuals with Down Syndrome (DS) in many countries, very little is produced on the life and education of such individuals in the United Arab Emirates. There is an apparent lack of societal interest in the quality of lives of people with DS. The condition of DS is nearly a taboo subject in this part of the world. With only a handful of pupils with DS included in regular schools, and with many myths and misconceptions surrounding the syndrome and individuals, particularly children with the syndrome, the first ever national support group for individuals with DS, their families and their carers was formed in late 2004 in the United Arab Emirates. This paper examines and evaluates the social and educational impact of the support group. The study particularly focuses on the role of such group in promoting social inclusion and inclusion of pupils with DS in regular schools in the UAE. Members (mainly parents of individuals with DS) of the newly-established group participated in two interviews six months apart and the researcher observed group meetings, recorded activities and events over the same period. Views of individuals with DS on the effects and the activities of the group were also gathered through semi-structured interviews.
Participants reported significant benefits from participating in the group, particularly in the areas of promoting social acceptance for individuals with DS. The study found that the group also helped in eliminating and correcting some of the myths surrounding the syndrome and played a role in promoting social and educational inclusion of such individuals. The study ends with a discussion of the findings and recommendations for future practice.  相似文献

Higher education policies related to quality assurance are implemented in many countries. The purposes of such policies are to ensure the provision for high-quality education, university accountability and transparency in the use of public funding and meeting the needs of the diverse stakeholders. The current Australian Higher Education Quality Assurance Framework was implemented in the year 2000. It can be described that the framework has been enjoyed by universities, academics and other providers in Australia. This paper provides a brief history of quality assurance, its evolution in higher education in Australia and current changes and trends in quality assurance in other developed countries. It then provides an analysis of the success and deficiencies of the current framework used in Australia and suggestions which may be helpful in the development of the new framework. The analysis includes the thoughts of the three authors based on their experience in managing quality and reviews in seven different institutions and the views of more than 40 participants who are staff members from 25 Australian universities.  相似文献

土生土长的福州道教,历史悠久,源远流长。由于福州山多水秀的优越地形的自然条件,早在秦汉时就有方士活动;及至东汉末三国孙吴时,又有道士活动踪迹,同时他们就在方山(福州五虎山,又称虎头山)建有自己活动场所洞元观。此后逐渐发展、繁荣。至宋代趋于鼎盛,明、清、民国时期日益衰微。由此可以看出福州道教文化的特点及演变过程。  相似文献

文学是文化的重要组成部分,现当代文学课对留学生文化知识的积累及语言交际能力的养成有着积极的作用。目前,以中国文学作为对外汉语文化教学内容的课程中,普遍存在重古代文学轻现当代文学,而现当代文学中重现代文学轻当代文学的倾向。事实证明留学生对当下中国的现实和鲜活俗白的语言最感兴趣,不论从语言难度还是内容呈现方面考虑,留学生现当代文学课都应该先由当代文学入手。而当代文学部分,要加大新世纪文学教学比重和分量。  相似文献

Utilizing 2068 individuals in 60 organizations in the U.S. and Italy, this study (a) examines the overall relationship between trust in top management and immediate supervisor and overall estimates of satisfaction and perceived organizational effectiveness, (b) compares the amount of variance in satisfaction and effectiveness that can be explained by trust in top management to the amount of variance explained by trust in immediate supervisor, and (c) clarifies the role of information receiving as a predictor of trust in top management and immediate supervisor. Results of a canonical correlation analysis indicated that the canonical equation explained 49% of the variance in the linear composites (Canonical R = .69, p < .001). Trust in top management was more strongly associated with satisfaction and effectiveness than was trust in immediate supervisor. Tzvo separate multiple regression analyses indicated that after controlling for geographic location of company and type of industry, information received about job and organizational issues uniquely explained 26% of the variance in trust in top management and 13% of the variance in trust in immediate supervisor.  相似文献

Heavy metal contamination of soils, derived from sewage irrigation, mining and inappropriate utilization of various agrochemicals and pesticides, and so on, has been of wide concern in the last several decades. The Shenyang Zhangshi Irrigation Area (SZIA) in China is a representative area of heavy metal contamination of soils resulting from sewage irrigation for about 30 years. This study investigated the spatial distribution and temporal variation of soil cadmium (Cd) and copper (Cu) contamination in the SZIA. The soil samples were collected from the SZIA in 1990 and 2004; Cd and Cu in soils was analyzed and then the spatial distribution and temporal variation of Cd and Cu in soils were modeled using Kriging methods. The results show that long-term sewage irrigation had caused serious Cd and Cu contamination in soils. The mean and the maximum of soil Cd are markedly higher than the levels in second grade standard soil (LSGSS) in China, and the maximum of soil Cu is close to the LSGSS in China in 2004 and is more than the LSGSS in China in 1990. The contamination magnitude of soil Cd and the soil extent of Cd con- tamination had evidently increased since sewage irrigation ceased in 1992. The contamination magnitude of soil Cu and the soil extent of Cu contamination had evidently increased in topsoil, but obviously decresed in subsoil. The soil contamination of Cd and Cu was mainly related to Cd and Cu reactivation of contaminated sediments in Shenyang Xi River and the import of Cd and Cu during irrigation. The eluviation of Cd and Cu in contaminated topsoil with rainfall and irrigation water was another factor of temporal-spatial variability of Cd and Cu contamination in soils.  相似文献

中国的泰语教学和泰国的中文教学具有悠久的历史,它的兴衰和发展,实际反映了两国关系的发展史。从公元1至15世纪,两国的交往主要靠"重译",即通过第3种语言转译。直至公元1578年明朝政府在四夷馆中开设暹罗馆,中国才有了官办的泰语教学。20世纪成立的南京东方语专是近现代中国泰语教学之滥觞。泰国的中文教学始于阿瑜托耶王朝时期,二战以前泰国华校亦是照搬中国学校的办学模式。二战以后泰国政府限制中文教学,致使泰国通晓中文的人才出现断层。中泰建交后两国的政治、经济、文化交流日益发展,催生了中国的泰语教学和泰国的中文教学的迅猛发展,具体的调查数字说明中泰双语教学的蓬勃兴旺,由此反映并进一步促进两国战略合作伙伴关系的发展。  相似文献

The purpose of this study was to survey a sample of high school students in Hawaii and Singapore about what they perceive to be helpful aspects of classroom environments in their learning of science and humanities subjects. The What Is Happening In this Class? (WIHIC) questionnaire was administered in the fall of 2003 to 73 high school students in Hawaii and 70 high school students in Singapore. These students were asked to respond to statements that focused on their actual and preferred environments in science and humanities classes for the three dimensions of learning environments of student cohesiveness, student involvement, and task orientation in the actual and preferred classroom. Principal component analyses were conducted separately for the data collected in the science and the humanities classes to make sure that the questions represented the anticipated factors in each of these two subject areas. A three-way multivariate analysis of variance was also conducted for all three dimensions of learning environments for differences in scores on items in the WIHIC questionnaire for the actual classroom subtracted from scores for the preferred learning environment. Results of this test revealed that the primary difference between students in high schools in Hawaii and Singapore was that students in the high schools in Hawaii wanted more student cohesiveness and involvement than the students in high schools in Singapore regardless of the subject. Another interesting finding was in the dimension of task orientation, for which the interaction between student nationality and subject was statistically significant.  相似文献
