信息伦理学研究中若干问题的思考

The further development of information ethics needs to solve some important ethic problems involved with disciplinary construction. These problems include the cause of the formation of information ethics; the research method,attribution and features of information ethics; the connotation and systematic structure of information ethics; the enlightenment we gain from the studies of the guiding principles of information ethics in foreign countries. The scientific analysis and exposition of these problems are helpful to the prosperity and perfection of information ethics and to the construction of social information ethics.

Contributions to a molecular phylogeny and systematics of Anemone and related genera (Ranunculaceae-Anemoninae)

 Plastid atpB/rbcL intergenic spacer sequences were obtained from 21 selected taxa and one hybrid of Anemoninae (Anemone, Pulsatilla, Hepatica) and compared with Ficaria (Ranun- culinae) as an outgroup. From the resulting matrix (1226 bp) a single most parsimonious tree was obtained (Fig. 1 ). The branching of this tree is confirmed by many informative indels and appears largely congruent with past plastid restriction analyses. Several new taxa are added. The monophyly of the Anemoninae and their early split into two major clades is supported: clade I with the chromo- some base number x = 8, clade Ⅱ with the reduced x = 7. Clade Ⅰ is made up of the basal Pulsatilla and the Rivularis + Vitifolia groups. The Multifida group links to the crown groups Coronaria, Blanda and Nemorosa. Clade Ⅱ consists of the basal Dichotoma group, followed by Hepatica, and finally by the N. Hemisphere Narcissiflora and the S. Hemisphere Antucensis groups as sisters. The problems of the Anemoninae ancestry, phylogenetic differentiation, and recent attempts for systemat- ic classification are critically discussed. In view of the still incomplete sampling of DNA data, aconservative and informal approach to classification problems is recommended.
