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

The pedagogical practices of mathematics education for young children in English and Korean pre-schools were compared through analyses of interviews with practitioners, observations of classroom activities and an examination of documents related to the planning and implementation of mathematics education. Practitioners in both countries used integrated activities to teach mathematics, although they used such activities more frequently in nurseries than in reception classes in England and more frequently in state settings than in independent settings in Korea. Furthermore, mathematics education was more structured, more likely to be led by an adult and less holistic in reception classes than in nurseries in England, whereas it was more structured and didactic in independent than in state settings in Korea. However, mathematics education in England was more systematic, used a more individualised approach and incorporated a variety of hands-on materials and rigorous outdoor activities, whereas it was more group-oriented and utilised limited materials and fewer outdoor activities in Korea.  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

A long and winding road awaits gifted females in Israel in their quest to actualize their potential in the sciences. The present state of affairs can be pieced together from a series of studies on various aspects related to the development in the sciences of females in general and gifted females in particular. Gender differences observed in the participation of students in challenging science programs and in their consequent achievement can be attributed to cognitive differences, to environmental and cultural emphasis, or to an interaction between cognitive and environmental factors, reflected in different preferences for methods of inquiry and differences in styles of problem solving. Examples of recent efforts in Israel that attempt to deal with observed gender differences and encourage females to fulfil their talents include group counseling programs, such as “Trapped in Blue and Pink” and instructional programs integrating counseling, such as “Na'aleh — Girls toward degrees in engineering” and a crosscultural intervention program for enhancing gifted females' achevement in the sciences via reattribution training.  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

The political changes occurring in eastern and central Europe in 1989 and 1990 and the breakup of the Union of Soviet Socialist Republics in 1991 fragmented a large area in which science and technology policy was more or less centralized and rationalized. Each country in this area, as a result, has had to develop its own science and technology policy in very difficult situations of transition. One of the attempts made to re‐establish some order and unity in science policy in the former socialist countries has been spearheaded by the International Association of Academies of Sciences, founded in Kiev in 1991. It is attempting, on a voluntary basis, to assume some of the functions of the former Soviet Academy of Sciences, and in particular, to re‐create the scientific space existing before 1989‐1991. Among its many projects are efforts in favour of young scientists and closer co‐operation with other international organizations of academies.  相似文献

This paper uses data from the Scottish School Leavers Surveys and the England and Wales Youth Cohort Study to analyse changes over time in gender and social class inequalities in the opportunities of young people to participate in higher education (HE) in Scotland, England and Wales. The results show that in Great Britain, in the period from the end of the 1980s to 2001–2002, HE expansion has benefited more women than men, and in the most recent time points has led to a reduction in social inequalities. However, gender and social class differences persist at degree level and in the choice of subject studied. The results also show that higher proportions of working class students enter HE in Scotland than in England and Wales, but that social inequalities are more marked in Scotland. The larger availability of vocational routes in Scotland, at both sub‐degree and degree level, may explain country differences in HE participation rate of working class students.  相似文献

The aim of this study was to evaluate attitudes towards and achievement in science of Form 3 students studying in single-sex and coeducational schools in Brunei. The results demonstrated significant differences in attitudes towards and achievement in science of male and female students in single-sex schools and students in coeducational schools. These differences were at moderate level. In single-sex schools, the girls achieved moderately better in science than the boys despite their attitudes were only marginally better than the boys. However, there were no gender differences in attitudes towards and achievement in science of students in coeducational schools. The attitudes towards and achievement in science of girls in single-sex schools were moderately better than those of girls in coeducational schools. Whereas the attitudes towards and achievement in science of boys in single-sex schools were only marginally better than the boys in coeducational schools. However, further research to investigate (a) if these differences are repeated at other levels as well as in other subjects, and (b) the extent to which school type contributed towards these differences is recommended.  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

The paper examines the impact of the plethora of innovations associated with the 1988 Education Reform Act (ERA) on the management of whole-school change in the primary school. Based upon qualitative data from a national sample of 50 schools in England and Wales, it documents the growing tensions between collegial and top-down managerial approaches. These are evidenced in the changing nature of working collaboratively in primary schools, in the creation of new management structures, in the me of school development plans and in the growth of quality assurance mechanisms, particularly in relation to preparation for Office for Standards in Education (OFSTED) inspections. There are conflicting interpretations of terms such as ‘collegiality’, ‘collaboration’, ‘teamwork’ and ‘whole-school approaches’ and there have been subtle shifts in their meaning and in their realisation in practice in the pre-and post-ERA context.  相似文献
