树木的拍摄

树木与人类息息相关,不论自觉或不自觉。人们都意识到,这个世界用于呼吸的空气,环境地球的大气,以及培植未来生物的土壤,全都依赖于树木的存在。人们应该利用摄影去表现春．夏、秋、冬四季树木的形态,表达树木的个性,抒发对大自然热爱的情感,通过摄影活动唤起人们保护自然的意识。     

基于技术引进、消化吸收的自主创新困境及消解对策

实现技术、经济的持续发展必须重视技术引进后的消化和吸收再创新.国家对于技术引进应有明确的战略目标,必须形成一套机制,有效地对国内企业实现激励、导向和制约的作用,促进企业技术引进后能够消化吸收进行自主创新.必须坚持制度创新,建立现代企业制度,使企业真正成为技术引进的主体、技术创新的主体.企业在引进技术时必须注重技术引进的先进性及本土化,技术引进后必须加大研发投入量并最终形成拥有自主知识产权的核心专利技术.     

浅谈生态建筑设计重点及重要性

如今生活在都市里的人都渴望回归自然,希望更多地与大自然接触,但住宅建筑仅有绿色还不能说其具有生态性,住宅的生态型是以绿色为基础涵盖生态环保,可持续发展等多种理念。首先就绿色本身而言,要达到国家有关标准,并具有完整的包括设计,施工,物业管理等多个环节的生命周期评价,且要和所有城市的整体环境质量相结合。其次是垃圾处理,污冰处理的就地化,实现生态最统内部有秩序的循环转换。垃圾就地处理及时,避免了在清运中的撒泄现象和因垃圾堆放而造成的污染。     

蚂蚁的"知音"——记美国生物学家爱德华·威尔逊

如果人类消失,地球上将欣欣向荣;如果蚂蚁消失,成千上万的生物将会跟着消失。20世纪初,著名的英国物理学家卢瑟福曾经骄傲地宣称:科学除了物理之外就是集邮。他的话语中显露出对科学中的博物学传统的轻蔑和不屑一顾。进入20世纪之后,各门科学的研究内容都越来越细致,从前那种"集邮"式的博物学者已经少之又少。但是,总有那么一些不合群的人,偏偏就喜欢研究那些别人不屑一顾的东西,当今的美国生物学家爱德华?威尔逊就是其中之一,他对一种小东西情有独钟。

中国拟兰亚科的研究

Apostasioideae, a small subfamily of Orchidaceae, is largely distributed in tropical Asia with its northern limit extending to the Ryukyu Islands and south China. The first Chinese species of this subfamily was reported by E. D. Merrill (1927) based on a specimen collected from Hainan (McClure 9519, AMES), which he regarded as Apostasia wallichii R. Br. As later labelled by E. F. de Vogel, it is in fact identical with A. odorata Bl., a widespread spe- cies also found in southern Guangdong, Guangxi and Yunnan of China.  It was not until re- cently that the true A. wallichii was collected from southwestern Yunnan bordering on Burma, which is initially reported here.  In addition, an interesting new species, A. ramifera S. C. Chen et K. Y. Lang, is described from Hainan.       The only Chinese species of Neuwiedia has long been known as N. veratrifolia Bl. (of. Iconographia Cormophytorum Sinicorum 5: 602, t. 8034. 1976, and Flora Hainanica 4 180, t. 1078. 1977), which, however, was considered by de Vogel (1969) to be not found in China.  In de Vogel's revision, no Chinese taxon but a variety, N. zollingeri Rchb. f. var. singapureana (Baker) de Vogel, is cited with some doubt based on a specimen of Hainan (F. C. How 73122, in young fruit, AMES). N. zollingeri var. singapureana is in fact quite different from N. veratrifolia by having glandular hair, much shorter inflorescence and flattened filaments.  As recently pointed out by de Vogel and G. Barretto (in Journ. Taiwan Museum 37: 78. 1984), the plants found in Hongkong, as well as those in Guangdong and Yunnan, possess glandular hair and short inflorescence. They are identical with the Vietnamese species N. balansae Gagnep., which was reduced by de Vogel to a synonym of N. zollingeri var singapureana. E. F. de Vogel's suggestion seems to be acceptable except the varietal rank.  It is treated here as a se- parate species, N. singapureana (Baker) Rolfe, according to its fruit and hair characters.  Thus we have altogether one species of Neuwiedia and three species of Apostasia in China, including a new species and a newly recorded one.

常山属的初步研究

Dichroa Lour., a small genus of Saxifragaceae, contains about 12 species, ranging from the mainland of S. E. Asia southward to Pacific islands. But most of the species are more restricted in distribution. Of the 12  recognized species,  six  are known from South China and Indochina; three are confined to west and northwest New Guinea; two are endemic to the Phillipines. Only one species is widely distributed in S. E. Asia.  In the present paper, the genus is divided into two sections  and two series based on the number of stamens and the characteristics of the ovary.  One spe- cies is described as new.

Information ethics as information ecology: Connecting Frankl’s thought and fundamental informatics

To overcome “digital reductionism,” a new kind of mechanical view on human beings, fundamental informatics provides some critical viewpoints. It regards information as “meaning” generated in living things which do not exist alone but are parts of ecological system. On the other hand, V. E. Frankl proposed two dimensions of humans: homo sapiens and homo patiens. The latter is the essential aspect of humans whose essence is “compassion,” while the former is the nature like a mechanical machine. As features of living things, unrestricted ability of interpretation as well as inseparable relationships between others underlies both in Frankl’s thought and fundamental informatics. This viewpoint can be applied to the concept of “information literacy.”

Flourishing Ethics

This essay describes a new ethical theory that has begun to coalesce from the works of several scholars in the international computer ethics community. I call the new theory ‚Flourishing Ethics’ because of its Aristotelian roots, though it also includes ideas suggestive of Taoism and Buddhism. In spite of its roots in ancient ethical theories, Flourishing Ethics is informed and grounded by recent scientific insights into the nature of living things, human nature and the fundamental nature of the universe – ideas from today’s information theory, astrophysics and genetics. Flourishing Ethics can be divided conveniently into two parts. The first part, which I call ‚Human-Centered FE,’ is focused exclusively upon human beings – their actions, values and characters. The second part, which I call ‚General FE,’ applies to every physical entity in the universe, including humans. Rather than replacing traditional ‚great ethical theories,’ Flourishing Ethics is likely to deepen and broaden our understanding of them.
