Learning from education to communicate science as a good story

Science communicators must learn from science educators in their crusade to counteract the traditional boring and inefficient approaches to convey science. Educators encounter a need for methods of teaching that portray science as 'hard fun' and resources that encourage students' minds to burst into action. Narratives are considered by several authors as highly valuable resources for science education. However, little research has been undertaken to measure the efficiency of narratives in the context of science communication to the general public. Recent work however, suggests that narratives are indeed an alternative and an important means for science communication to convey information in an accurate, attractive, imaginative and memorable way. To present scientific information through stories, novels, comics and plays should be regarded as an important means to transmit information in the repertoire of both science teachers and science communicators.     

Crowding in and crowding out within a contribution good model of research

In standard economic theory, government support of science is expected to confer external benefits and ‘crowd-in’ additional private sector research. However, higher rates of economic growth from this effect are not easily discerned from the long run data, and government and business financed R&D have moved in opposite directions (as a proportion of GDP) since the early 1960s in the US and elsewhere. This paper looks at potential sources of ‘crowding out’ as well as ‘crowding in,’ and compares standard analysis with a ‘contribution good’ model of science. Two different policy issues are identified – the assembly of ‘critical mass’ for the ‘kick starting’ of commercial science, and the expansion of commercial science beyond its ‘private equilibrium’. We analyse the allocation of scarce business as well as scientific skills between sectors. The model produces regions of both crowding in and out. The latter dominates for very high wages in the public sector as the government deprives the private sector of the means to exploit new knowledge.     

研究人员发现肌肉老化原因 有望带来抗肌肉衰老新疗法

人在衰老的过程中,肌肉的力量会越来越小,对于肌肉损伤的修复能力也会不断下降。最近,一国际研究小组发现,一种名为FGF2的蛋白在这一过程中扮演着重要角色,而通过小鼠研究表明,利用常规药物可以阻止这一进程。这一研究发现对于了解肌肉老化的进程十分重要,且使得未来开发可使肌肉"返老还童"的     

加强领导增大力度扎扎实实地做好科技援藏工作

中央第三次西藏工作座谈会确定，山东省重点支援日喀则、白朗、昂仁、聂拉木4个市县。几年来，我们认真贯彻落实党中央、国务院关于援藏工作的指示精神，把支援日喀则地区的发展纳入我省科技工作的总体规划，采取切实措施，加大工作力度，使对口科技支援工作取得了明显成效。据不完全统计，自1995年以来，我省与日喀则地区签定对口支援项目566项，投资总额60437．42万元，已完成和正在实施的项目565项，到位资金52587．42万元。这些项目的组织实施，其中也凝聚了我省广大科技工作者的心血。它们效益的发挥，对日喀则地区经济发展、社会稳定和藏族同胞脱贫致富起到了积极的促进作用。     

论科学技术“内在亦善亦恶”观及其意义

科学技术应用过程中存在善恶问题的观点已得到普遍认可。除此之外,科学技术也具有内在的善和恶,科学技术"内在亦善亦恶"。树立"科学技术内在亦善亦恶观",对于科学技术的研发,使之更好的为人类服务和避免危害人类发展等方面都具有重要意义。     

财政科技投入对经济贡献的动态综合估计

 采用状态空间模型进行变系数估计,同时采用向量自回归模型、脉冲响应函数、方差分解分析财政科技投入与经济的动态交互效应。状态空间模型的研究结果表明,每年财政科技投入对经济贡献的弹性系数处于不稳定的正负波动中,绝对值较小。脉冲响应函数和方差分解的结果表明,科技投入与经济增长之间的互动关系要弱于劳动力与经济增长的关系,科技投入与资本的互动关系要强于科技投入与劳动力的互动关系。状态回归模型、脉冲响应函数、方差分解的结果是可以互相验证和互相补充的。     

The emergence of China as a leading nation in science

China has become the fifth leading nation in terms of its share of the world's scientific publications. The citation rate of papers with a Chinese address for the corresponding author also exhibits exponential growth. More specifically, China has become a major player in critical technologies like nanotechnology. Although it is difficult to delineate nanoscience and nanotechnology, we show that China has recently achieved a position second only to that of the USA. Funding for R&D has been growing exponentially, but since 1997 even more in terms of business expenditure than in terms of government expenditure. It seems that the Chinese government has effectively used the public-sector research potential to boost the knowledge-based economy of the country. Thus, China may be achieving the (“Lisbon”) objectives of the transition to a knowledge-based economy more broadly and rapidly than its western counterparts. Because of the sustained increase in Chinese government funding and the virtually unlimited reservoir of highly skilled human resources, one may expect a continuation of this growth pattern in the near future.     

人文社会科学研究中科学精神发展的历史趋势

科学精神是人文社会科学研究的必然属性,不是自然科学的专利。这可以从人文社会科学发展链条得到证明。在古希腊,自然哲学研究诞生了科学精神,逻辑和理性由此产生。从文艺复兴时代起,人文社会学科研究中的现代科学精神逐渐形成。进入现代,在科学与人文的互动中现代科学精神成为人文社会学科发展中不可或缺的因素。

政府科技投入对我国技术进步的贡献

在现代社会里，技术进步对一个国家的经济增长起着至关重要的作用。本文基于我国1953～2002年度的统计数据，建立相关的数学模型，定量测算了政府科技投入对我国技术进步的贡献率，得出结论：政府科技投入对我国技术进步的贡献率偏低，从改革开放后至2002年的整个时期里，政府科技投入对技术进步的平均贡献率只有8．3％；因此，我国应当努力加大政府科技投入的力度，以促进我国技术进步水平的进一步提高，继而推动我国经济的快速增长。最后，文章提出了几点关于加大我国政府科技投入的建议。
