AIDS education started very early in Zimbabwe and is now compulsory in all schools. This evaluation documents the development of the primary and secondary school AIDS Action Programme from 1991 to 1998. Six programme aspects were evaluated: programme start-up, planning and management, development of syllabi and materials, teacher training, research, monitoring and evaluation, and co-ordination. The Programme drew on resources from within the existing educational system. Due to broad-based consultation and participation, it was supported by Government and partners. Flexible management ensured implementation of mid-course corrections. It was concluded that school AIDS programmes should stress participatory teaching and learning methods and life-skills training. Curriculum writers and teachers needed training and supervision in participatory techniques. Cluster workshops between district and school levels were needed to strengthen the cascade model of teacher training that had been adopted. Systematic research, monitoring and evaluation were essential, including follow-ups to baseline surveys. The Zimbabwean programme was well-designed, relatively inexpensive and replicable.  相似文献

The extent of carcinogen regulation under existing U.S. environmental statutes is assessed by developing measures of the scope and stringency of regulation. While concern about cancer risk has played an important political role in obtaining support for pollution control programs, it has not provided the predominant rationale for most regulatory actions taken to date. Less than 20% of all standards established to limit concentrations of chemicals in various media address carcinogens. Restrictions on chemical use are more frequently based on concerns about noncancer human health or ecological effects. Of the chemicals in commercial use which have been identified as potential human carcinogens on the basis of rodent bioassays, only a small proportion are regulated. There is an inverse relationship between the scope of regulatory coverage and the stringency of regulatory requirements: the largest percentages of identified carcinogens are affected by the least stringent requirements, such as information disclosure. Standards based on de minimis cancer risk levels have been established for only 10% of identified carcinogens and are restricted to one medium: water. Complete bans on use have affected very few chemicals. The general role that carcinogenicity now plays in the regulatory process is not dramatically different from that of other adverse human health effects: if a substance is identified as a hazard, it may eventually be subject to economically achievable and technically feasible restrictions.  相似文献

This 1998 evaluation assessed the peer education programmes of HIV/AIDS projects run by four non-governmental organisations. A mini-case study approach was used and analysis was based on cross-case itemistic variables. The projects were assessed only in terms of immediate developmental outcomes to target groups rather than on long-term impact. The study concluded the following: (1) The projects had raised community awareness of HIV/AIDS; (2) Basic knowledge of HIV/AIDS was for the most part accurate; (3) There was anecdotal evidence of behavioural changes in terms of partner-reduction as reported by the projects, though the evidence was sometimes conflicting; and (4) There was evidence that certain traditional practices, which contributed to the spread of the virus (e.g. sexual cleansing and scarification), were becoming modified over time. The programmes were also instrumental in protecting human rights and enabling people living with HIV/AIDS to maintain human dignity.  相似文献

深入分析历年硕士研究生入学英语考试英译汉试题的特点,总结四方面特点,提出具有针对性的翻译方法和技巧作为对策:(1)试题中的词汇难以见词明义,需根据上下文选择确定词义或对词义进行引申;(2)句子的理解与翻译对上下文的依赖性很强,需使用还原法对原文中的替代、省略、变换等表达进行还原翻译;(3)句子较长,结构复杂,需采用分译法;(4)很多句子的表意方式和语序体现出英美人的思维习惯和特点,需作语序调整。  相似文献

对于财政收入主要来源于农业经济的农村地区 ,乡镇财政的压力既推动了乡镇政权组织发展本地经济 ,同时也导致了乡镇政权组织加大财政提取力度 ,甚至为此不惜违反国家有关法律和政策 ,从而削弱了基层政权的合法性基础 ,加剧了农村社会矛盾。要改善农业地区的乡镇治理状况 ,必须结合农业主导型乡镇财政的特点改革农村管理体制。  相似文献

归入权问题之研究   总被引:1,自引:0,他引:1  
通过对归入权行使对象、行使主体、行使范围的论述 ,对《证券法》第 42条的修改提出了相关建议 :归入权行使对象应当扩大 ,行使主体不仅应包括董事会、监事会、股东 ,在一定条件下 ,证监会也可以作为行使主体。在计算归入权的收益上可采取最高卖价减最低买价法予以计算。  相似文献

现在美国的经济增长速度开始放缓 ,而欧盟的经济状况在经历两年的调整之后进入一个比较稳定的发展阶段。从理论上来讲欧元的汇率应该有一个坚挺的趋势 ,但事实却相反 ,欧元却一直走弱。本文通过欧盟和美国对欧元态度的对比 ,对这种现象做了一些分析。美国出于自身的利益考虑不希望欧元走强 ;而欧盟各国也都乐于看到欧元疲软 ;与此同时市场投资者也对欧元信心不足。这些态度其实成了解释欧元汇率的走势为什么屡屡出乎预测家的估计 ,一直保持相对弱势的关键原因  相似文献

This article looks at STTEP, an outreach project currently housed at the University of Pretoria, which concentrates on the teaching of western orchestral instruments, plus background areas such as music theory, to disadvantaged children and youth from a variety of townships around Pretoria, South Africa. STTEP’s direction can well be described as ‘right’ – pupils are already surrounded by all kinds of global phenomena, and their formal music studies in western classical music are not making them forget their roots. In fact, the contrary has been found to be the case and some interesting cultural fusions are already seen – always a sign of a living culture.  相似文献

采用半经验的AM1方法研究了共聚物-(PPP)m-(PT)n-中性态和带电态的稳定构型,中性态下界面处的扭转角为25°时构型最稳定,带电态下界面处的扭转角为0°时构型最稳定.在AM1优化的基础上采用ZINDO方法研究共聚物界面处构象的改变对其光吸收性质的影响,计算发现共聚物-(PPP)m-(PT)n-的电子光吸收谱将依赖于界面处扭转角的变化,扭转角从0°到90°变化时,中性态下第一、二、三激发跃迁能随扭转角的增加而增加,而且随分子链长的变短和含苯环比例的增大,此种变化趋势越显著;在掺杂两个电荷的情况下,第一、二、三激发跃迁能随扭转角的增加而减小.  相似文献
