教师:工作哪儿去了

学校以教学工作为中心!尽管现在社会赋予学校许多职能,教育改革要求学校重新思考在新的历史变革中的定位,但学校教学中心的地位不能变。校长以管理为主!市场经济曾经让个别校长热衷于创收,杂乱的事务也确实使校长烦恼,但精明的校长都知道,管理不能丢,管理出质量、出效益。     

健康永远第一

中华民族近现代历史上,我们永远不会忘却帝国主义炮火中的辱国丧权,但“东亚病夫”的蔑视同样令人刻骨铭心。一个国家,经济、科学技术的落后,政治腐败要挨打,一个民族,教育的落后、全民体质的下降,将不战自败!     

Ethical issues of behavior modification research in schools

Behavior modification research in the classroom was examined by the National Commission for the Protection of Human Subjects because of the increasingly widespread use of behavioral procedures in the schools, the effectiveness of these procedures in changing academic and social behavior, and the consequent concern about potential misuse. In order to foster the responsible use of behavior modification procedures in the schools on a practical as well as a research basis, the following ethical issues being considered by researchers and the involved public are discussed: informed consent, determination of classroom goals, legitimacy of rewards and aversive controls in the classroom, conceptions of behavior modification as manipulative and mechanistic, who can implement the procedures, research design, and accountability. The authors conclude that the issues regarding protection of human subjects in behavior modification research are no different from other treatment-oriented research with children. However, the high degree of parental and teacher involvement in both research and practice requires shared responsibility for the prevention of misuse of behavior modification procedures.     

浅析旨在企业拯救的破产重整制度

新破产法于2007年6月1日正式开始实施,其中第八章规定了一个原来我国没有的广义的破产所包含的程序即破产重整程序。困境企业并不是一定要选择清算退出市场,我们可以依法律对其进行一系列的重整再建工作,病马理论说是"治病救马"而不是"杀马分肉"。本文从破产法立法理念的转变入手,阐述了重整制度的概念和产生的背景,并重点讨论了破产重整制度所产生的理论根据,即营运价值论、利益与共论和社会政策论。     

一种基于.NET和VBA互操作模型的Web报表实现方法

针对在B/S结构下生成Web报表比较复杂的情况,讨论了三种常用的Web报表生成方案:直接利用Win32API编程接口设计报表、采用水晶报表编辑器设计报表和使用第三方控件生成报表。在分析了上述三种方案的优缺点基础上,文章提出了一种比较实用的基于.Net和VBA(Visual Basic for Applications)互操作模型的Web报表设计方法。实际应用效果表明:采用该模型进行Web设计具有易用性强、灵活性高等优点,同时能够节约软件开发成本10%左右。并且验证了该模型的有效性和可靠性。     

技术密集型企业跨国并购对创新绩效的影响——基于中国A股上市公司的经验研究

以中国A股上市公司2013年至2017年中发生跨国并购的技术密集型上市公司为样本,检验跨国并购对其创新绩效的影响,并就不同专利产出类型分别回归检验.结果 显示,技术密集型企业跨国并购对创新绩效有显著促进作用,但是促进作用最大的并不是发明专利.在此基础上,提出技术密集型企业应创造条件通过跨国并购来提高创新绩效,应加强并购...     

ENSO and Southeast Asian biomass burning modulate subtropical trans-Pacific ozone transport

Trans-Pacific transport of enhanced ozone plumes has been mainly attributed to fossil fuel combustion in Asia in spring, but less attention has been paid to vegetation fires in Asia. Here we show that the El Niño-Southern Oscillation (ENSO)-modulated fires in Southeast Asia, rather than Asian fossil fuel plumes, dominate the interannual variability of springtime trans-Pacific transport of ozone across the entire North Pacific Ocean. During El Niño springs, the intensified fires from both the Indochinese Peninsula and Indonesia, together with large-scale circulation anomalies, result in enhanced ozone plumes that stretch over 15 000 km in both the lower-middle and upper troposphere. This enhancement is also observed in the in situ measurements of ozone concentration, with an almost 10% increase at Mauna Loa Observatory, Hawaii, a unique site to monitor the long-distance transport over the North Pacific. This study reports an unexpectedly strong influence of vegetation fires, linked with climate variability, on global tropospheric chemistry and proves once more how complex the interactions in the climate system are.
