据阳光农业相互保险公司董事长梁敏先生介绍:“中国农业保险自1982年开始恢复,到高峰期的1992年,农业险保费收入达8,2亿元,但赔付率高达116%, 完全是亏本经营。从1996年起,农业保险规模逐年萎缩,2001年农业保险规模跌到20多年来的最低谷,农险保费收入仅3亿元,占保险业总保费的0.14%,农业保险深度仅为0.02%,是近20年来下滑幅度最大的一年。全国2.3亿农户,户均保费不足2元。”是什么原因造成现在这种局面呢?记者以电子邮件形式采访了梁敏先生。充满曲折的中国农业保险“这主要在于中国农业保险存在六大缺失”,梁敏先生这样在电子邮件里答复,“要想解决这个问题,需要先从其发 相似文献

Construction kits have played a significant part in nurturing the growth and development of the minds and manipulation-based
skills of children (and adults) in formal and non-formal education settings. These kits have origins rooted in the representation
of the built world and now have a diversity of form and function, including technical versions with moving parts. This article
examines some of the historically based ideas that lie behind the role that kits may have in terms of physical modelling.
The article traces the transformation of kits from simple bricks and blocks into more complicated pieces for space-filling
and achieving the transfer of forces and motion. This transformation occurred during the Victorian era when the influence
of the ideas of educationalists and, perhaps rather strangely, exponents of early aviation, played major roles in determining
the diversity of forms of construction kit and modelled possibilities that are now to be seen in classrooms and homes. The
article ends with a review of some of the lessons from the past and present that will need to be considered in relation to
concrete modelling in schools for the future.

In this article the impact of technology education, as a new learning area (subject) in the curriculum, on in-service teacher
education in South Africa is described in order to ascertain the extent of the impact. The research on which this article
is based draws on a variety of experiences and observations in the field at grassroots level (in particular an outreach project
in rural communities). The envisaged impact of technology education on South African schools, communities, teacher educators
and teachers, the range of in-service teacher education that is required, and the impacts in urban and rural areas are discussed.
Finally a number of concluding remarks are made about the extent of the impact of the inclusion of technology education in
the new National Curriculum Statement and whether the situation has changed since the implementation of a pilot technology
education project in 1998.

语言是人类最早的技术发明,由于作为一种传播媒介的文字可以分为象形文字和拼音文字,它们在处理音、形、意三者关系时的不同策略使它们拥有各自的独特品质,使得它们在打破人在口语时代所形成的感官平衡的同时,形成了不同的感官比率,由此内在地定制了两种不同文化的特征. 相似文献

随着城市居民最低生活保障制度的实施和不断完善,城市贫困人群的生活得到了一定程度的改善。但是,在现有体制下,贫困人群的医疗问题日益凸显出来,他们在医疗方面实际上处于一种双重缺失状态,如果不解决好这个问题,有可能会影响到整个社会保障制度的完善和社会的稳定。 相似文献

That survey research is error prone is not a new idea and different varieties of non-sampling error have been investigated
in the literature as well as consideration being given in many statistics textbooks to the issue of sampling error. The paper
here considers research upon corporate environmental reporting. It compares information provided by corporate environmental
reports with information that survey respondents claim their organization’s environmental report contains. This enables the
accuracy of the claims to be assessed. Consideration is given to two different industries the Water industry and the Energy
industry. Errors due to inaccurate reporting by survey respondents are shown to be relatively infrequent and respondents appear
just about as likely to claim they report information that they do not, in fact, report as to fail to indicate that they report
information that is, in fact, actually reported. 相似文献
