教育观念的更新和变革,是课程改革顺利进行的必要前提和关键所在。要牢固树立“以人为本”的教育理念,以突出素质教育的全体性、全面性、主体性。教学过程要实现从单向信息传递向师生交往互动的变革、从单纯的知识灌输向学生认知建构的变革、从单纯应试向促进学生可持续发展的变革。教师必须形成新的角色意识,做学生学习的指导者、做教学的研究者和终身学习的示范者。同时,新课程改革还要求开展学习方式的革命。 相似文献

两岸入世后,台湾当局的大陆经贸政策与世界贸易组织的要求是有一定距离的,特别是台湾当局为大陆度身设置的“大陆货品特殊防御机制”,似乎是为了利用中国大陆在其《入世议定书》中对世贸组织成员的特别的承诺条款,但从法律角度而言,这是有违台湾在世贸组织《保障措施协议》项下的义务的,极易成为两岸之间有限的经贸互动中争端的导火绳。 相似文献

A survey was conducted in Lilongwe city urban markets in Malawi, to assess the quality of cooking oil used for frying potato chips. Purposive sampling was performed to come up with respondents who were using vegetable oils. A stratified random sampling was used to select the 32 informal food processors who were interviewed using a structured questionnaire. Oil samples were collected from the most commonly used brand of oil. Fifteen respondents were selected and these were divided into three categories of five: those who were not reusing the oil, those who were reusing the oil and those who were preparing potato chips and chicken in the same oil, for chemical analysis. The preliminary results showed that while the majority (59.4%) of the informal food processors discarded the oil after 1 day, 3.1% discarded it after 4 days and another 12.5% after 3 days. A larger proportion of the respondents (40.6%) used the leftover oils at home, 37.5% kept it in oil bottles, 3.1% kept it in plastic papers for reuse the following day. Also, most respondents (57%) indicated dark colour as the sign of oil deterioration, 29% discarded the oil after noticing foam formation while 8.2% and 6.1% said they discarded the oil after noticing a bad smell and food absorbing the oils respectively. A physical observation of the various oils showed that for most of the respondents (34%), the oils were dark brown in colour, in 22%, the oils were slightly dark brown and 16%, the oils were brown. Foam formation was noticed in 13% of the respondents. It was also noted that 91% of the respondents had not been trained or briefed of food quality and safety issues. A chemical analysis of the oils showed high values of free fatty acids (range, 0.84–1.4112 compared with 0.42 in the fresh oil) and peroxide values (range 14.7–16.6 compared with 9.0 in the fresh oil). It may be concluded that the oils being used by the informal food processors in Malawi are of poor quality and so the foods cooked in them may be a health hazard to the consumers and the processors themselves. Although this work in ongoing, it may be recommended at the outset that the health department of the city assemblies should inspect these oils for the good health of the consumers. 相似文献

Managerial Equity Ownership and the Demand for Outside Directors 总被引:1,自引:0,他引:1
This paper examines the linkage between the use of outside directors and managerial ownership. We conjecture there are two linkages: the standard incentive‐alignment demand for monitoring when managers own little stock and an entrenchment‐amelioration demand when managerial stock ownership is high. As a consequence, we predict the association between managerial ownership and board composition will be nonlinear (U‐shaped if the entrenchment effect is sufficiently pronounced). Using UK data, we find that both quadratic and logarithmic models outperform the simple linear relationship assumed in prior research and that the substitution between managerial ownership and board composition is stronger than hitherto supposed. 相似文献
