论党在早期工人运动中解决帮会问题的策略

中国共产党成立以后就着手开展工人运动 ,首先遇到的障碍是帮会。由于在工厂、码头、矿山、货栈等有劳苦工人的地方 ,几乎都有帮会的活动 ,又由于帮会在思想上禁锢着工人群众的觉悟 ,在组织上限制着工人群众的自由 ,阻碍工人运动的发展。为此 ,我党制定了一系列妥善处理帮会的策略 ,排除了帮会对工人运动的干扰 ,有力地推动了中国革命。     

Relationship between R&D expenditures and publication output for U.S. colleges and universities

Two large independent sources of data, NSF's University Science Statistics Program Integrated Data Base and CHI Research's bibliometric data base, are brought together in a comprehensive study of the relationships among research resources, as measured by R&D expenditures, and research output, as measured by the quantity and visibility of scientific journal articles. The study is based on approximately 500 U.S. colleges and universities. For each of 11 fields of science, there is strong indication of a linear relationship between R&D expenditures and number of papers. The evidence also indicates a positive relationship between number of cites received per paper and number of papers published, but only for papers published in the basic research journals of the fields of chemistry, physics, and biology.

实事求是--审计哲学的灵魂

审计属于社会活动的范畴,与其他社会活动一样遵循着同样的社会规律。但是,日常的微观审计往往忽视审计哲学的研究与作用。审计同样需要哲学,审计哲学就是实事求是。实事求是原则不仅是实现三个代表的重要体现,而且是审计监督的内在要求,是审计实践经验的总结和理论概括,是审计的指导思想和方法论。     

Tandem Biocatalysis by CotA-TJ102@UIO-66-NH2 and Novozym 435 for Highly Selective Transformation of HMF into FDCA

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production.

Teachers’ technology adoption and practices: lessons learned from the IWB phenomenon

The twenty-first century has seen unprecedented investment from governments around the world in educational technologies in schools. This paper investigates Australian teachers’ adoption and use of a popular technology that has been extensively supported by governments and school systems: the interactive whiteboard (IWB). The study suggests that a number of the barriers identified in the early days of adoption and use of this technology, such as professional support and access, still remain for many teachers, thereby impeding effective practices. The research also found that primary school teachers were using the technology in diverse ways, in contrast to secondary teachers who were using the IWB mainly for instructionist, presentational purposes. We conclude by considering various ways of reducing the effect of the identified barriers to support implementation of educational technologies in the classroom, especially the next generation of technologies promoted by governments and systems.
